PART I
1. Business

 Overview

Arbutus Biopharma Corporation (“Arbutus”, “we”, “us”, and “our”) is a publicly traded industry-leading therapeutic solutions company focused on discovering, developing and commercializing a cure for patients suffering from chronic hepatitis B (HBV) infection, which leads to serious liver disease.  Effective July 31, 2015, our corporate name changed from Tekmira Pharmaceuticals Corporation to Arbutus Biopharma Corporation. Our pipeline is focused on finding a cure for chronic HBV infection. This HBV pipeline consists of multiple drug candidates, with complementary mechanisms of action, which we expect to use in combination to effect patient benefit.

HBV represents a significant unmet medical need and is the cause of the most common serious liver infection in the world. The World Health Organization estimates that 350 million people worldwide are chronically infected, and other estimates suggest this could include approximately 2 million people in the United States (Kowdley et al., 2012). Individuals chronically infected with HBV are at an increased risk of developing significant liver disease, including cirrhosis, or permanent scarring of the liver, as well as liver failure and hepatocellular carcinoma (HCC) or liver cancer. According to the Hepatitis B Foundation, HBV is the cause of up to 80% of liver cancers. Individuals with liver cancer typically have a five-year survival rate of only 15%. The WHO estimates that more than 780,000 people die every year due to the consequences of hepatitis B virus disease.

Given the complex biology of HBV (as shown in the graphic below), we believe combination therapies are the key to HBV treatment and a potential cure, and development can be accelerated when multiple components of a combination therapy regimen are controlled by the same company.






HBV Focused Product Pipeline

We have a pipeline focused on finding a cure for chronic HBV infection, with the objective of developing a combination of products that intervene at different points in the viral life cycle. Given our strong scientific and research capabilities in-house, we are able to conduct preclinical combination studies to evaluate combinations of our proprietary pipeline candidates. Once compounds within the portfolio with sufficient activity have been identified, we intend, subject to discussions with regulatory authorities, to evaluate combinations of two or more drug candidates in cohorts of patients with chronic HBV infection. We expect to use these results to adaptively design additional treatment regimens for the next cohorts. We also plan to evaluate different treatment durations to determine the optimal finite duration of therapy. We plan to continue this iterative process until we select combination therapy regimens and treatment durations to conduct Phase III clinical trials intended to ultimately support regulatory filings for marketing approval. Our pipeline of HBV product candidates includes:


We intend to continue to expand our HBV pipeline through internal development, acquisitions and in-licenses. We also have a research collaboration agreement with The Baruch S. Blumberg Institute, a non-profit research institute established by the Hepatitis B Foundation, that provides exclusive rights to in-license any intellectual property generated through the collaboration. For more information about this agreement please refer to the “Strategic Alliances, Licensing Agreements, and Research Collaborations” section of this annual report on Form 10-K below.

RNAi (ARB-1467 & ARB-1740)

The development of RNA Interference (RNAi) drugs allows for a completely novel approach to treating disease, which is why RNAi is considered one of the most promising and rapidly advancing frontiers in drug discovery. While there are no RNAi therapeutics approved for commercial use, there are a number of RNAi products currently in human clinical trials. RNAi products are broadly applicable as they can eliminate the production of disease-causing proteins from cells, creating opportunities for therapeutic intervention that have not been achievable with conventional drugs. Our extensive experience in antiviral drug development has been applied to our RNAi program to develop therapeutics for chronic hepatitis B infection. Small molecule nucleotide therapy has been the standard of care for chronic HBV infected patients. However, many of these patients continue to express a viral protein called HBV surface antigen (HBsAg). This protein causes inflammation in the liver leading to cirrhosis and, in some cases, HCC and death.


7



Our lead RNAi HBV candidate, ARB-1467 (formerly TKM-HBV), is designed to eliminate HBsAg expression in patients chronically infected with HBV. Reducing HBsAg is thought to be a key prerequisite to enable a patient’s immune system to raise an adequate immune response against the virus. The ability of ARB-1467 to inhibit numerous viral elements in addition to HBsAg increases the likelihood of affecting the viral infection. ARB-1467 is being developed as a multi-component (3-trigger) RNAi therapeutic that simultaneously targets three sites on the HBV genome, including the HBsAg coding region. Targeting three distinct and highly conserved sites on the HBV genome is intended to facilitate potent knockdown of all viral mRNA transcripts and viral antigens across a broad range of HBV genotypes and reduce the risk of developing antiviral resistance.


ARB-1467 results in potent and rapid reduction in HBsAg in several preclinical models. In these models, ARB-1467 treatment resulted in reductions in both intrahepatic and serum HBsAg, as well as reductions in HBV DNA, cccDNA, Hepatitis B e antigen (HBeAg) and HBcAg (Hepatitis B c antigen). A rapid 1 log reduction in serum HBsAg was achieved with a single 1 mg/kg dose of ARB-1467 in the humanized mouse model. 1-2 log viral reductions from similar single-dose LNP treatments in two other true-infection animal models were also demonstrated. Preclinical studies conducted on infected primary human hepatocytes showed that ARB-1467 had robust and consistent activity against different viral strains representing the major clinical genotypes A, B, C and D. Our data shows that inclusion of three RNAi triggers results in a more broadly effective knockdown of hepatitis B viral elements than a single trigger alone. The mode of action of ARB-1467 complements standard of care nucleoside/nucleotide (NUC) therapy, and lack of drug antagonism has been demonstrated with entecavir, lamivudine and tenofovir on infected primary human hepatocytes, making combination therapy a viable option. This data was presented at the DIA/FDA Oligonucleotide-Based Therapeutics Conference in Washington, DC, in September 2015. We presented additional data at the 2015 International Meeting on Molecular Biology of Hepatitis B Viruses in Dolce Bad Nauheim, Germany, in October 2015, and at the 2015 AASLD Liver Meeting in San Francisco in November 2015.

In early 2015, we advanced two RNAi product candidates (ARB-1467 and ARB-1468) into a Phase I Single Ascending Dose (SAD) trial. Both product candidates employ the same unique combination of three RNAi trigger molecules; however, they differ in their LNP composition. ARB-1467 employs a third generation LNP, and ARB-1468 employs a new, fourth generation LNP, which incorporates novel lipid chemistry and demonstrates improved potency in preclinical studies. The Phase I clinical trial is a randomized, single-blind, placebo-controlled study, involving single ascending doses of ARB-1467 and ARB-1468. The study is assessing the safety, tolerability and pharmacokinetics of intravenous administration of two LNP formulations (third and fourth generation) of the product in healthy adult subjects. In order to enable maximum dose escalation, steroid premedication was added to the Phase I protocol. No dose limiting toxicities were seen with either formulation through 0.4mg/kg, the highest dose tested in Phase I. At this time, a maximum tolerated dose has not been reached and the protocol has been amended to allow evaluation of higher doses. ARB-1467 was selected to progress to a Phase II multi-dosing study in HBV infected patients.

8




The Phase II study evaluates two dose levels of ARB-1467 administered as three monthly doses in chronic HBV infected patients who are on stable background nucleot(s)ide analog therapy. Eight subjects will be enrolled in each of the two dose cohorts with six subjects receiving ARB-1467, and two receiving placebo. The ARB-1467 Phase II multi-dosing study has been initiated and single dose and multi-dose HBsAg reduction data are expected in the second half of 2016.

While we are focused on development of our lead HBV product candidates, we believe in continuous innovation and will incorporate technological and product design advancements that may result in an improvement in safety and/or efficacy. An example of this is our follow-on RNAi HBV candidate, ARB-1740. ARB-1740 is more potent than ARB-1467 in preclinical studies and has the potential to be effective at lower clinical doses than ARB-1467. ARB-1740 employs the same LNP formulation as ARB-1467 (with a different set of three RNAi triggers). We plan to file an IND (or equivalent filing) for ARB-1740 in the second half of 2016.

cccDNA Formation Inhibitors

We are developing small molecule cccDNA formation inhibitors. The inhibition of cccDNA formation is expected to reduce the amount of cccDNA in the infected liver by blocking the formation of new cccDNA. We acquired the exclusive, worldwide rights to this program through an in-license from the Blumberg Institute. We have made significant progress with the discovery of potent and small molecule cccDNA formation inhibitors. As presented at the 2015 International Meeting on Molecular Biology of Hepatitis B Viruses in October 2015, our cccDNA formation inhibitors demonstrate synergy with approved nucleot(s)ide analogs in preclinical models, which could lead to faster declines in cccDNA levels in patients than is seen with nucleot(s)ide analogs alone. We plan to file an IND (or equivalent filing) for our lead cccDNA formation inhibitor in the second half of 2016.

Core Protein/ Capsid Assembly Inhibitors

HBV core protein, or capsid, is required for viral replication and core protein may have additional roles in cccDNA function. Current nucleot(s)side analog therapy significantly reduces serum HBV DNA levels in the serum but significant HBV replication continues in the liver, thereby enabling HBV infection to persist. Effective therapy for patients requires new agents which will effectively block viral replication. We are developing core protein inhibitors (also known as capsid assembly inhibitors) as oral therapeutics for the treatment of chronic HBV infection. By inhibiting assembly of the viral capsid, the ability of hepatitis B virus to replicate is impaired, resulting in reduced cccDNA. We acquired exclusive, worldwide rights to these drug candidates through an in-license from Blumberg and Drexel University, or (“Drexel”), and through Arbutus Inc.’s acquisition of Enantigen Therapeutics, Inc. (“Enantigen”). We plan to file an IND (or equivalent filing) for our lead candidate in the second half of 2016.

TLR9 Agonist (ARB-1598)

Immune stimulation by toll-like receptor (TLR) agonists may overcome the immunologic blocks that allow chronic HBV persistence, including direct activation of the host’s innate antiviral response. Licensed from Cytos Biotechnology Ltd., (“Cytos”), ARB-1598 (formerly CYT003) is a biological carrier which is filled with the immunostimulatory oligonucleotide called G10, a TLR-9 agonist. ARB-1598 has been shown to directly activate B cells and stimulates human plasmacytoid dendritic cells to secrete Interferon alpha, and has previously been utilized in human trials in other indications. ARB-1598 also activates other antigen presenting cells indirectly and promotes the development of TH1 type cytokine response, which is thought to be potentially beneficial in promoting anti-HBV T cell immunity. ARB-1598 is undergoing preclinical evaluation to establish its utility for HBV, and if there is a clear support for this application, we plan to initiate clinical development of ARB-1598 in chronically infected HBV patients in 2016.

Other Research Programs

Surface Antigen Secretion Inhibitors

We are developing multiple small molecule orally bioavailable inhibitors of HBV surface antigen production and secretion. By inhibiting the production and secretion of HBV surface antigen from infected cells, we expect that the immune response of patients treated with this therapy can reengage and thereby mount a more credible response to a hepatitis B virus infection.

cccDNA Epigenetic Modifiers

In addition to cccDNA formation inhibitors, we are developing cccDNA epigenetic modifiers. By controlling cccDNA transcription, we anticipate that we may be able to inhibit the formation of new virus and sub viral particles from cccDNA. This development program, which is currently in the discovery research stage, is based on proof of concept data generated by Blumberg using known inhibitors of enzymes involved in DNA information processing.

STING Agonists

We are developing stimulator of interferon genes (STING) agonists. By activating interferon genes, we anticipate that the body can produce additional interferon alpha and beta, which have antiviral properties. Our development program, which is currently in the discovery research stage, is based on proof of concept data in mice generated by Blumberg which showed that STING agonists can elicit an antiviral response and inhibit HBV replication in mouse liver cells. In collaboration with Blumberg, our plan is to identify potent, orally active small molecule human STING agonists that possess the desired characteristics to progress into human clinical studies.

Cyclophilin Inhibitor (OCB-030)

We licensed from NeuroVive Pharmaceutical AB, or (NeuroVive), the exclusive rights to develop and commercialize cyclophilin inhibitor drug candidates, including OCB-030, for the treatment of hepatitis B. After extensive preclinical evaluation of OCB-030 and other competitive cyclophilin inhibitors against HBV, we have concluded that cellular cyclophillins do not play a role in HBV chronic infection and further development of OCB-030 is unwarranted. As a result, we made the decision in October 2015 to discontinue the development of OCB-030 and have suspended our interest in the cyclophilin inhibitor class.

Our Proprietary Delivery Technology

Development of RNAi therapeutic products is currently limited by the instability of the RNAi trigger molecules in the bloodstream and the inability of these molecules to access target cells or tissues following administration. Delivery technology is necessary to protect these drugs in the bloodstream to allow efficient delivery and cellular uptake by the target cells. Arbutus has developed a proprietary delivery platform called Lipid Nanoparticle, or LNP. The broad applicability of this platform to RNAi development has established Arbutus as a leader in this new area of innovative medicine.

Our proprietary LNP delivery technology allows for the successful encapsulation of RNAi trigger molecules in LNP administered intravenously, which travel through the bloodstream to target tissues or disease sites. LNPs are designed to protect the triggers, and stay in the circulation long enough to accumulate at disease sites, such as the liver or cancerous tumors. LNPs are then taken up into the target cells by a process called endocytosis. Subsequent activation by the changing environment inside the cell causes the LNP to release the trigger molecules, which can then successfully mediate RNAi.

10




Ongoing Advancements in LNP Technology

Our LNP technology represents the most widely adopted delivery technology in RNAi, which has enabled several clinical trials and has been administered to hundreds of human subjects. Because LNP can enable a wide variety of nucleic acid triggers, including mRNA, we continue to see new product development and partnering opportunities based on our industry-leading delivery expertise and intellectual property. We presented preclinical data in October 2013 at the International mRNA Health Conference in Tubingen, Germany, and in February 2014 at the AsiaTIDES Conference in Toyko, Japan. This data demonstrated that mRNA encapsulated and delivered using our proprietary LNP technology can be effectively delivered and expressed in the liver in tumors and other specific tissues of therapeutic interest.

Arbutus continues to explore opportunities to generate value from its LNP platform technology, which is well suited to deliver therapies based on RNAi, mRNA, gene editing, as well as other technologies.

Suspended Non-HBV RNAi Assets

Our intent is to focus our efforts on discovering, developing and commercializing a cure for patients suffering from chronic HBV infection. As such, pending completion of ongoing studies associated with TKM-PLK1, we have suspended further development of our non-HBV assets and are exploring different strategic options to maximize the value of these assets. Our non-HBV assets include our LNP-based product candidates TKM-PLK for oncology, TKM-Ebola and TKM-Marburg for hemorrhagic fever viruses, TKM-HTG for metabolic disorders, and TKM-ADLH for severe alcohol use disorder.

Oncology (TKM-PLK1)

Our oncology product platform, TKM-PLK1, targets PLK1, a protein involved in tumor cell proliferation and a validated oncology target. Inhibition of PLK1 expression prevents the tumor cell from completing cell division, resulting in cell cycle arrest and death of the cancer cell. Evidence that patients with elevated levels of PLK1 in their tumors exhibit poorer prognosis and survival rates has been documented in the medical literature. TKM-PLK1 is being evaluated in the following oncology indications where there are limited or ineffective therapies available: Gastrointestinal Neuroendocrine Tumors (GI-NET), Adrenocortical Carcinoma (ACC) and Hepatocellular Carcinoma (HCC). We are exploring partnering or external funding opportunities to maximize the value of our oncology related assets.


11



TKM-PLK1: GI-NET and ACC

GI-NET is the gastrointestinal subset of neuroendocrine tumors with an estimated U.S. prevalence of 55,000 individuals. Prognosis for advanced or metastatic GI-NET, the target population for TKM-PLK1, is poor with 25-54% of patients surviving less than one year. ACC is an extremely rare form of cancer that develops in the adrenal gland. Data from the U.S. National Cancer Institute indicates there are approximately 500 patients in the U.S. with ACC. Survival prognosis for patients with ACC is poor. A large percentage of patients are not good surgical candidates and there is a lack of effective systemic therapies.

We presented Phase I TKM-PLK1 data at the 6th and 8th Annual NET Conferences hosted by the North American Neuroendocrine Tumor Society (NANETS) in October 2013 and October 2015. Based on encouraging results from the dose escalation portion and expansion cohort from our Phase I TKM-PLK1 clinical trial, we expanded into a Phase I/II clinical trial with TKM-PLK1, which enrolled patients within the two therapeutic indications: advanced GI-NET or ACC. This multi-center, single arm, open label study was designed to measure efficacy using RECIST criteria for GI-NET patients and ACC patients as well as evaluate the safety, tolerability and pharmacokinetics of TKM-PLK1 in a population of 63 subjects with advanced solid tumors, including 15 subjects with GI-NET. TKM-PLK1 was administered weekly with each four-week cycle consisting of three once-weekly doses followed by a rest week. We provided an update on the Phase I/II GI-NET clinical study in October 2015 at the NANETS conference.

In the GI-NET population, one subject, a "remarkable responder" had a maximal 61.1% decrease in target tumor at cycle 2. This subject remained on-study for 10 cycles and the partial tumor response (PR) was stable throughout this period. Twelve of 13 evaluable subjects had a best response of stable disease (SD) or PR. Duration of SD/PR ranged from two to 14 cycles. In the ACC population one subject, a "remarkable responder" had a maximal 48.7% decrease in target tumor at cycle 14. After 18 cycles, the residual tumor was resected and histopathology showed near-complete necrosis, at which time the subject discontinued the study. Five of eight evaluable subjects had a best response of SD or PR. Duration of SD/PR ranged from two to 18 cycles. Therapy with TKM-PLK1 was received for up to 18 months and was generally well tolerated by the majority of subjects. The TKM-PLK1 GI-NET/ACC trial has concluded.

TKM-PLK1: HCC

HCC is one of the most common cancers, one of the most deadly and a common outcome of chronic HBV infection, with over 650,000 deaths each year worldwide according to the Globocan 2012 database. US incidence is estimated at 27,000 individuals with annual growth rates greater than 2%. HCC is an aggressive, hard-to-treat disease with one-year survival rates of less than 50% and five-year rates as low as 4% (National Cancer Institute). To date, Nexavar (sorafenib) is the only agent approved to treat HCC with an improvement in overall survival of just two to three months.

In June 2014, we initiated another Phase I/II clinical trial with TKM-PLK1, enrolling patients with advanced HCC. Patient dosing has commenced and we have completed the dose escalation portion of this trial. This Phase I/II clinical trial is a multi-center, single arm, open label dose escalation study designed to evaluate the safety, tolerability and pharmacokinetics of TKM-PLK1 as well as determine the maximum tolerated dose in patients with advanced inoperable HCC. It will also include a preliminary assessment of the anti-tumor activity of TKM-PLK1 in this patient population. In August 2015 we announced initiation of patient dosing in the expansion cohort of the clinical trial at multiple sites in Canada, the United States and Asia, and have since completed enrollment. An assessment of efficacy in terms of tumor response in approximately 20 subjects will take place upon trial completion and results are expected in 2016.

Other Infectious Diseases (TKM-Ebola and TKM-Marburg)

We have suspended further development of our RNAi product candidates targeting filoviruses Ebola and Marburg. In December 2014, the U.S. Congress amended the FDA Priority Review Voucher (PRV) Program Act to add filoviruses as a candidate for a PRV. We are exploring partnering or external funding opportunities to maximize the value of these assets.

TKM-Ebola-Kikwit has been developed under a $140 million contract with the U.S. Department of Defense (DoD) awarded in July 2010. Given the unclear development path for TKM-Ebola, development activities have been suspended and the contract with the DoD has been terminated. TKM-Ebola-Kikwit completed the single ascending dose portion of the Phase I clinical trial in healthy human volunteers. Results demonstrated that administration of the TKM-Ebola-Kikwit therapeutic, in the absence of any steroid containing pre-medication, was well-tolerated at a dose level of 0.3 mg/kg, determined to be the maximum tolerated dose. Under the FDA’s expanded access program, several patients with a confirmed or suspected Ebola virus infection were treated with TKM-Ebola-Kikwit during the ebola outbreak in 2014. In March 2015, a TKM-Ebola-Guinea Phase II single arm trial called Rapid Assessment of Potential Interventions & Drugs for Ebola (RAPIDE) was initiated in Sierra Leone, led by the International Severe Acute Respiratory and Emerging Infection Consortium (ISARIC) at the University of Oxford, UK, with funding from the Wellcome Trust. In June 2015 we announced closing of the enrollment for the trial as it reached a futility boundary, which was a predefined statistical endpoint. The results of the study have been submitted for publication and the manuscript is under review.

We have several publications related to our Ebola and Marburg RNAi therapeutic candidates. In April 2015, we, along with our collaborators at the University of Texas Medical Branch (UTMB) at Galveston, USA, published positive Ebola treatment data in the journal Nature (Thi EP., et al.; Nature, April 2015). Data demonstrated 100% survival of nonhuman primates previously infected with the West African Makona strain of Ebola virus even when treatment did not begin until three days after viral exposure a time point at which animals were five to six days away from death. These efficacy results are comparable to those obtained with TKM-Ebola-Kikwit, which also demonstrated up to 100% protection from an otherwise lethal dose of the virus. We have published data demonstrating complete protection of non-human primates against lethal Marburg-Angola strain, (Thi EP., et al.; Science Translational Medicine, Aug 2014). Selected data from these programs was presented at the Chemical and Biological Defense Science and Technology Conference in May 2015.

Metabolic Disorders (TKM-HTG)

TKM-HTG is a multi-component RNAi therapeutic that simultaneously targets a combination of genes expressed in the liver, which are known to play a significant role in triglyceride metabolism. High triglyceride levels are medically linked to increased risk of cardiovascular disease, fatty liver disease, insulin resistance and pancreatitis. Approximately one million adults in the US and 18 million worldwide suffer from severe HTG. (NHANES 2003-2004 data). Another patient group affected by HTG are those with Familial Chylomicronemia Syndrome (FCS), which is a very rare hereditary condition affecting an estimated 1:1,000,000 people (www.fcs.raredr.com). Additionally, 35% of patients with Type 2 Diabetes (T2D) suffer from mixed hyperlipidemia which is a combination of elevated cholesterol and high triglycerides. With underlying T2D, these patients are at considerable risk from cardiovascular disease. We are exploring partnering or external funding opportunities to maximize the value of this asset.

Alcohol Use Disorder (TKM-ALDH)

TKM-ALDH is designed to knockdown or silence aldehyde dehydrogenase (ALDH) to induce long term acute sensitivity to ethanol, for use in severe alcohol use disorder. Aldehyde dehydrogenase is a key enzyme in ethanol metabolism. Inhibition of ALDH activity, through the silencing of ALDH, results in the build-up of acetaldehyde leading to adverse physiological effects. Human proof of concept for ALDH inhibition already exists in the form of the approved drug disulfiram. However, disulfiram’s efficacy is compromised by poor compliance because it has to be taken daily. We believe TKM-ALDH will induce prolonged ethanol sensitivity that will enable it to overcome the compliance limitations associated with daily dosing. We are exploring partnering or external funding opportunities to maximize the value of this asset.

Partner Programs

Patisiran (ALN-TTR02)

Alnylam Pharmaceuticals, Inc., or Alnylam, has a license to use our intellectual property (IP) to develop and commercialize products and may only grant access to our LNP technology to its partners if it is part of a product sublicense. Alnylam’s license rights are limited to patents that we have filed, or that claim priority to a patent that was filed, before April 15, 2010. Alnylam does not have rights to our patents filed after April 15, 2010 unless they claim priority to a patent filed before that date. Alnylam will pay us low single digit royalties as Alnylam’s LNP-enabled products are commercialized. More information about our licensing agreement with Alnylam can be found under the “Strategic Alliances, Licensing Agreements, and Research Collaborations” section of this report.

In April 2014, Alnylam presented positive new data from its Phase II clinical trial with patisiran, an RNAi therapeutic targeting transthyretin (TTR) for the treatment of TTR-mediated amyloidosis (ATTR). These results provide additional support for Alnylam's Phase III APOLLO trial. In October 2014, Alnylam reported positive clinical data for the ongoing patisiran Phase II Open Label Extension (OLE) study in patients with Familial Amyloidotic Polyneuropathy (FAP). The results demonstrated sustained knockdown of serum TTR of up to 90% and a favorable tolerability profile out to one year of treatment. In April 2015, Alnylam announced positive data from the ongoing open-label study with patisiran which demonstrated continued evidence for possible halting of neuropathy progression after the first 12 months of treatment. In addition, patisiran treatment showed robust mean knockdown of serum TTR of up to 88%. Alnylam's ongoing OLE study is an open-label, multi-center trial designed to evaluate the long-term safety and tolerability of patisiran administration in FAP patients that were previously enrolled in a Phase II study. In July 2015, Alnylam announced initiation of a Phase III open label OLE study with patisiran (APOLLO-OLE) to evaluate the long-term safety and tolerability of patisiran in ATTR amyloidosis patients with FAP who were previously enrolled in the APOLLO Phase III study. In September 2015, Alnylam reported evidence of reduced pathogenic, misfolded TTR monomers and oligomers in TTR-mediated amyloidosis patients with FAP, and in November 2015 it reported that patisiran demonstrates continued evidence for potential halting of neuropathy progression and improvement in nerve fiber density in patients with FAP. New Drug Application (NDA) filing for this program is expected in 2017.

The patisiran program represents the most clinically advanced application of our LNP delivery technology. Furthermore, Alnylam’s results demonstrate that multi-dosing with our LNP has been well-tolerated with treatments out to 21 months.

Marqibo®

Marqibo®, originally developed by Arbutus, is a novel, sphingomyelin/cholesterol liposome-encapsulated formulation of the FDA-approved anticancer drug vincristine. Marqibo’s approved indication is for the treatment of adult patients with Philadelphia chromosome-negative acute lymphoblastic leukemia (Ph-ALL) in second or greater relapse or whose disease has progressed following two or more lines of anti-leukemia therapy. Our licensee, Spectrum Pharmaceuticals, Inc. (Spectrum), launched Marqibo through its existing hematology sales force in the United States. We are entitled to mid-single digit royalty payments based on Marqibo’s commercial sales. Spectrum has ongoing trials evaluating Marqibo in three additional indications, which are: first line use in patients with Philadelphia Negative Acute Lymphoblastic Leukemia (Ph-ALL), Pediatric ALL and Non-Hodgkin’s lymphoma. More information about our licensing agreement with Spectrum can be found under the “Strategic Alliances, Licensing Agreements, and Research Collaborations” section of this report.

We entered an arbitration proceeding with Alnylam, as provided for under our licensing agreement, to resolve a matter related to a disputed $5 million milestone payment to Arbutus from Alnylam related to its ALN-VSP product. The arbitration proceeding with Alnylam has concluded resulting in no milestone payment to Arbutus.

Acuitas Therapeutics Inc.

Consistent with the terms of the settlement agreement signed in November 2012, we finalized and entered a cross-license agreement with Acuitas Therapeutics Inc., or Acuitas in December 2013. The terms of the cross-license agreement provide Acuitas with access to certain of our earlier IP generated prior to April 2010. At the same time, the terms provide us with certain access to Acuitas’ technology and licenses in the RNAi field, along with a percentage of each milestone and royalty payment with respect to certain products. Acuitas has agreed that it will not compete in the RNAi field for a period of five years, ending in November 2017.

Merck & Co., Inc. and Alnylam License Agreement

As a result of the settlement between Protiva Biotherapeutics, Inc. (Protiva), and Merck & Co., Inc. in 2008, we acquired a non-exclusive royalty-bearing world-wide license agreement with Merck. Under the license, Merck will pay up to $17 million in milestones for each product they develop covered by our IP, except for the first product for which Merck will pay up to $15 million in milestones, and will pay royalties on product sales. Merck’s license rights are limited to patents that Protiva filed, or that claim priority to one of Protiva’s patents that was filed, before October 9, 2008. Merck does not have rights to Protiva patents filed after October 9, 2008 unless they claim priority to a patent filed before that date. On March 6, 2014, Alnylam announced that they acquired all assets and licenses from Merck, which included our license agreement.

Dicerna Pharmaceuticals, Inc.

In November 2014, we signed a licensing agreement and a development and supply agreement with Dicerna to license our LNP delivery technology for exclusive use in Dicerna's PH1 development program. Dicerna will use Arbutus’ third generation LNP technology for delivery of DCR-PH1, Dicerna's product incorporates its DsiRNA molecule, for the treatment of PH1, a rare, inherited liver disorder that often results in kidney failure and for which there are no approved therapies. Under the agreements, Dicerna paid Arbutus $2.5 million upfront and will potentially make payments of $22 million in aggregate development milestones, plus a mid-single-digit royalty on future PH1 sales. This partnership also includes a supply agreement under which we will provide clinical drug supply and regulatory support for the rapid advancement of this product candidate.

Monsanto Company

In January 2014, we signed an Option Agreement and a Service Agreement with Monsanto Company, or Monsanto, and granted Monsanto an option to obtain a license to use our proprietary LNP delivery technology. The transaction supports the application of LNP technology and related IP for use in agriculture. The potential value of the transaction could reach $86.2 million following the successful completion of milestones. In January 2014, we received $14.5 million of the $17.5 million in near term payments. We received additional payments of $1.5 million each in June 2014 and October 2014 following the achievement of specific program objectives. In May 2015, the arrangement was amended to extend the option period by approximately five months, with payments up to $2.0 million for the extension period. As of December 31, 2015, we have received $19.3 million. Following the completion of the Phase A extension period in October 2015, no further research activities were conducted under the arrangement, as Monsanto did not elect to proceed to Phase B of the research plan.

On March 4, 2016, Monsanto exercised its option to acquire 100% of the outstanding shares of Protiva Agricultural Development Company Inc., or PADCo, and will pay Arbutus an exercise fee of $1 million. As a result, PADCo is no longer an indirect wholly owned subsidiary of us. In connection with Monsanto’s exercise of its option, on March 4, 2016, we entered into an amended Option Agreement. We also entered into an amended Service Agreement on March 4, 2016 to give effect to the grant back to Protiva of new intellectual property created by Monsanto in connection with the exercise of its option. In addition, we entered into an amended License and Services Agreement to recognize Monsanto’s early exercise of option before Protiva’a completion of Phases B and C, and introduce a new Technology Transfer Completion Criteria through the amended Option Agreement. Each of the amended Option Agreement, amended License and Services Agreement and amendment to the Service Agreement have been filed as Exhibits to this annual report on Form 10-K.

Spectrum Pharmaceuticals, Inc.

In September 2013, we announced that our licensee, Spectrum, had launched Marqibo® through its existing hematology sales force in the United States. Since then commercial sales have occurred. Arbutus is entitled to mid-single digit royalty

15



payments based on Marqibo®’s commercial sales. Marqibo®, which is a novel sphingomyelin/cholesterol liposome-encapsulated formulation of the FDA-approved anticancer drug vincristine, was originally developed by Arbutus. We out-licensed the product to Talon Therapeutics in 2006, and in July 2013, Talon was acquired by Spectrum. Marqibo®’s approved indication is for the treatment of adult patients with Philadelphia chromosome-negative acute lymphoblastic leukemia (Ph-ALL) in second or greater relapse or whose disease has progressed following two or more lines of anti-leukemia therapy. Spectrum has ongoing trials evaluating Marqibo® in three additional indications, which are: first line use in patients with Ph-ALL, Pediatric ALL and Non-Hodgkin’s lymphoma.

Marina Biotech, Inc. /Arcturus Therapeutics, Inc.

 In November 2012, we disclosed that we had obtained a worldwide, non-exclusive license to a novel RNAi trigger technology called Unlocked Nucleobase Analog (UNA) from Marina Biotech Inc., or Marina, for the development of RNAi therapeutics. UNAs can be incorporated into RNAi drugs and have the potential to improve them by increasing their stability and reducing off-target effects. In August 2013, Marina assigned its UNA technology to Arcturus Therapeutics, Inc., or Arcturus, and the UNA license agreement between us and Marina was assigned to Arcturus. The terms of the license are otherwise unchanged.

To date, we have paid Marina $0.5 million in license fees and there are milestones of up to $3.2 million plus royalties for each product that we develop using UNA technology licensed from Marina.  We announced on January 21, 2015, that we had initiated a Phase I clinical trial with TKM-HBV (RNAi). As TKM-HBV utilizes UNA technology in-licensed from Arcturus, the initiation of the trial triggered a single milestone payment of $250,000 payable by us to Arcturus.

U.S. National Institutes of Health

On October 13, 2010 we announced that together with collaborators at the University of Texas Medical Branch (UTMB), we were awarded a new NIH grant, worth $2.4 million, to support research to develop RNAi therapeutics to treat Ebola and Marburg hemorrhagic fever viral infections using our LNP delivery technology. In February 2014, we along with UTMB and other collaborators were awarded additional funding of $3.4 million over five years from the NIH in support of this research.

Bristol-Myers Squibb Company

In May 2010, we announced a research collaboration with Bristol-Myers Squibb Company, BMS. Under this agreement, BMS conducted preclinical work to validate the function of certain genes and shared the data with us to potentially develop RNAi therapeutic drugs against therapeutic targets of interest. We formulated the required RNAi trigger molecules enabled by our LNP technology to silence target genes of interest. BMS paid us $3.0 million concurrent with the signing of the agreement. We provided a predetermined number of LNP batches over the four-year agreement. In May 2011, we announced a further expansion of the collaboration to include broader applications of our LNP technology and additional target validation work. In May 2014, the collaboration expired and all parties’ obligations ended.

Halo-Bio RNAi Therapeutics, Inc.

In August 2011, we entered into a license and collaboration agreement with Halo-Bio RNAi Therapeutics, Inc., or Halo-Bio. Under the agreement, Halo-Bio granted to us an exclusive license to its multivalent ribonucleic acid MV-RNA technology. The agreement was amended on August 8, 2012, to adjust future license fees and other contingent payments. To date, we have recorded $0.5 million in fees under our license from Halo-Bio. We terminated the agreement with Halo-Bio on July 31, 2013. There are no further payments due or contingently payable to Halo-Bio.

Aradigm Corporation

In December 2004, we entered into a licensing agreement with Aradigm Corporation, or Aradigm, under which Aradigm exclusively licensed certain of our liposomal intellectual property for the pulmonary delivery of Ciprofloxacin. As amended, this agreement calls for milestone payments totalling $4.5 and $4.75 million, respectively, for the first two disease indications pursued by Aradigm using our technology, and for low- to mid-single-digit royalties on sales revenue from products using our technology. We terminated the Aradigm license agreement in May 2013.

University of British Columbia

Certain early work on lipid nanoparticle delivery systems and related inventions was undertaken at the University of British Columbia, or UBC. These inventions are licensed to us by UBC under a license agreement, initially entered in 1998 as

16



amended in 2001, 2006 and 2007. We have granted sublicenses under the UBC license to Alnylam as well as to Spectrum (Talon Therapeutics Inc., acquisition). Alnylam has in turn sublicensed back to us under the licensed UBC patents for discovery, development and commercialization of RNAi products. In mid-2009, we and our subsidiary Protiva entered into a supplemental agreement with UBC, Alnylam and Acuitas Technologies, Inc., in relation to a separate research collaboration to be conducted among UBC, Alnylam and Acuitas to which we have license rights. The settlement agreement signed in late 2012 to resolve the litigation among Alnylam, Acuitas, Arbutus and Protiva provided for the effective termination of all obligations under such supplemental agreement as between and among all litigants.

On November 10, 2014, the University of British Columbia filed a demand for arbitration against Arbutus Biopharma Corp., BCICAC File No.: DCA-1623. We received UBC’s Statement of Claims on January 16, 2015. In its Statement of Claims, UBC alleges that it is entitled to $3.5 million in allegedly unpaid royalties based on publicly available information, and an unspecified amount based on non-public information. UBC also seeks interest and costs, including legal fees. We dispute UBC’s allegation. No dates have been scheduled for this arbitration.

Cytos Biotechnology Ltd

On December 30, 2014, Arbutus Inc., our wholly owned subsidiary, entered into an exclusive, worldwide, sub-licensable (subject to certain restrictions with respect to licensed viral infections other than hepatitis) license to six different series of compounds from Cytos Biotechnology Ltd., or Cytos. The licensed compounds are Qbeta-derived virus-like particles that encapsulate TLR9, TLR7 or RIG-I agonists and may or may not be conjugated with antigens from the hepatitis virus or other licensed viruses. We have an option to expand this license to include additional viral infections other than influenza and Cytos will retain all rights for influenza, all non-viral infections, and all viral infections (other than hepatitis) for which we have not exercised an option.

In partial consideration for this license, we will be obligated to pay Cytos up to a total of $67 million for each of the six licensed compound series upon the achievement of specified development and regulatory milestones; for hepatitis and each additional licensed viral infection, up to a total of $110 million upon the achievement of specified sales performance milestones; and tiered royalty payments in the high-single to low-double digits, based upon the proportionate net sales of licensed products in any commercialized combination.

The Baruch S. Blumberg Institute and Drexel University

In February 2014, Arbutus Inc., our wholly owned subsidiary, entered into a license agreement with The Blumberg S. Blumberg Institute, or Blumberg, and Drexel University, or Drexel, that granted an exclusive (except as to certain know-how and subject to retained non-commercial research rights), worldwide, sub-licensable license to three different compound series: cccDNA inhibitors, capsid assembly inhibitors and HCC inhibitors.

In partial consideration for this license, Arbutus Inc. paid a license initiation fee of $150,000 and issued warrants to Blumberg and Drexel. No warrants were outstanding as at the date Arbutus merged with Arbutus Inc. Under this license agreement, Arbutus Inc. also agreed to pay up to $3.5 million in development and regulatory milestones per licensed compound series, up to $92.5 million in sales performance milestones per licensed product, and royalties in the mid-single digits based upon the proportionate net sales of licensed products in any commercialized combination. We are obligated to pay Blumberg and Drexel a double digit percentage of all amounts received from the sub-licensees, subject to customary exclusions.

In November 2014, Arbutus Inc. entered into an additional license agreement with Blumberg and Drexel pursuant to which it received an exclusive (subject to retained non-commercial research rights), worldwide, sub-licensable license under specified patents and know-how controlled by Blumberg and Drexel covering epigenetic modifiers of cccDNA and STING agonists. In consideration for these exclusive licenses, Arbutus Inc. made an upfront payment of $50,000. Under this agreement, we will be required to pay up to $1.0 million for each licensed product upon the achievement of a specified regulatory milestone and a low single digit royalty, based upon the proportionate net sales of compounds covered by this intellectual property in any commercialized combination. We are also obligated to pay Blumberg and Drexel a double digit percentage of all amounts received from its sub-licensees, subject to exclusions.

License Agreements between Enantigen and Blumberg and Drexel

In October 2014, Arbutus Inc., our wholly owned subsidiary, acquired all of the outstanding shares of Enantigen Therapeutics, Inc., or Enantigen, pursuant to a stock purchase agreement. Through this transaction, Arbutus Inc. acquired a HBV surface antigen secretion inhibitor program and a capsid assembly inhibitor program, each of which are now assets of Arbutus, following our merger with Arbutus Inc.

17




Under the stock purchase agreement, we agreed to pay up to a total of $21.0 million to Enantigen’s selling stockholders upon the achievement of specified development and regulatory milestones, for the first two products that contain either a capsid compound, or a HBV surface antigen compound that is covered by a patent acquired under this agreement; or a capsid compound from an agreed upon list of compounds. The amount paid could be up to a total of $102.5 million in sales performance milestones in connection with the sale of the first commercialized product by us for the treatment of HBV, regardless of whether such product is based upon assets acquired under this agreement; and low single digit royalty on net sales of such first commercialized HBV product, up to a maximum royalty payment of $1.0 million that, if paid, would be offset against our milestone payment obligations.

Under the stock purchase agreement, we also agreed that Enantigen would fulfill its obligations as they relate to the three patent license agreements with Blumberg and Drexel. Pursuant to each patent license agreement, Enantigen is obligated to pay Blumberg and Drexel up to approximately $500,000 in development and regulatory milestones per licensed product, royalties in the low single digits, and a percentage of revenue it receives from its sub-licensees.

Research Collaboration and Funding Agreement with Blumberg

In October 2014, Arbutus Inc., our wholly owned subsidiary, entered into a research collaboration and funding agreement with Blumberg under which we will provide $1.0 million per year of research funding for three years, renewable at our option for an additional three years, for Blumberg to conduct research projects in HBV and liver cancer pursuant to a research plan to be agreed upon by the parties. Blumberg has exclusivity obligations to Arbutus with respect to HBV research funded under the agreement. In addition, we have the right to match any third party offer to fund HBV research that falls outside the scope of the research being funded under the agreement. Blumberg has granted us the right to obtain an exclusive, royalty bearing, worldwide license to any intellectual property generated by any funded research project. If we elect to exercise our right to obtain such a license, we will have a specified period of time to negotiate and enter into a mutually agreeable license agreement with Blumberg. This license agreement will include the following pre negotiated upfront, milestone and royalty payments: an upfront payment in the amount of $100,000; up to $8.1 million upon the achievement of specified development and regulatory milestones; up to $92.5 million upon the achievement of specified commercialization milestones; and royalties at a low single to mid-single digit rates based upon the proportionate net sales of licensed products from any commercialized combination.

NeuroVive Pharmaceutical AB

In September 2014, Arbutus Inc., our wholly owned subsidiary, entered into a license agreement with NeuroVive that granted us an exclusive, worldwide, sub-licensable license to develop, manufacture and commercialize, for the treatment of HBV, oral dosage form sanglifehrin based cyclophilin inhibitors (including OCB-030). Arbutus Inc. became our wholly owned subsidiary by way of a Merger Agreement, which does not trigger any milestone payments. Under this license agreement we have been granted a non-exclusive, royalty free right and license and right of reference to NeuroVive’s relevant regulatory approvals and filings for the sole purpose of developing, manufacturing and commercializing licensed products for the treatment of HBV. Under this license agreement, we have (1) an option to expand our exclusive license to include treatment of viral diseases other than HBV and (2) an option, exercisable upon specified conditions, to expand our exclusive license to include development, manufacture and commercialization of non-oral variations of licensed products for treatment of viral diseases other than HBV. NeuroVive retains all rights with respect to development, manufacture and commercialization of licensed products and non-oral variations of licensed products for all indications (other than HBV) for which we have not exercised our option.

In partial consideration for this license, Arbutus Inc. paid NeuroVive a license fee of $1 million. We have conducted significant research and analysis on the NeuroVive Product, OCB-030. Based on this research and analysis, we have decided to discontinue the OCB-030 development program. Otherwise, the license agreement and ongoing relationship with NeuroVive remains in full effect at this time.

Patents and Proprietary Rights

Our commercial success depends in part on our ability to obtain and maintain proprietary protection for our drug candidates, novel discoveries, product development technologies and other know-how, to operate without infringing on the proprietary rights of others and to prevent others from infringing our proprietary rights. Our policy is to seek to protect our proprietary position by, among other methods, filing or in licensing U.S. and foreign patents and patent applications related to our proprietary technology, inventions and improvements that are important to the development and implementation of our business. We also rely on trademarks, trade secrets, know how, continuing technological innovation and potential in licensing opportunities to develop and maintain our proprietary position.

In addition to our proprietary expertise, we own a portfolio of patents and patent applications directed to HBV cccDNA formation inhibitors, HBV core/capsid protein assembly inhibitors, TLR-9 agonists, HBV surface antigens secretion inhibitors, HBV cccDNA epigenetic modifiers, STING agonists, cyclophilin inhibitors, LNP inventions, LNP compositions for delivering nucleic acids such as mRNA and siRNA, the formulation and manufacture of LNP-based pharmaceuticals, chemical modification of RNAi molecules, and RNAi drugs and processes directed at particular disease indications. We have filed many patent applications with the US and European Patent Offices that have been granted. In the US our patents might be challenged by interference or opposition proceedings. In Europe, upon grant, a period of nine months is allowed for notification of opposition to such granted patents.  If our patents are subjected to interference or opposition proceedings, we would incur significant costs to defend them. Further, our failure to prevail in any such proceedings could limit the patent protection available to our therapeutic HBV programs or RNAi platform, including our product candidates.

We have a portfolio of approximately 121 patent families, in the U.S. and abroad, that are directed to our therapeutic HBV product candidates and various aspects of LNPs and LNP formulations. The portfolio includes approximately 83 issued U.S. patents, approximately 100 issued non-U.S. patents, and approximately 350 pending patent applications, including the following patents and applications in the United States and Europe (1) :

* Once issued, the term of a US patent first filed after mid-1995 generally extends until the 20th anniversary of the filing date of the first non-provisional application to which such patent claims priority. It is important to note, however, that the United States Patent & Trademark Office, or USPTO, sometimes requires the filing of a Terminal Disclaimer during prosecution, which may shorten the term of the patent. On the other hand, certain patent term adjustments may be available based on USPTO delays during prosecution. Similarly, in the pharmaceutical area, certain patent term extensions may be available based on the history of the drug in clinical trials. We cannot predict whether or not any such adjustments or extensions will be available or the length of any such adjustments or extensions.

Employees

At December 31, 2015, Arbutus had 134 employees, 105 of whom were engaged in research and development. None of our employees are represented by a labor union or covered by a collective bargaining agreement, nor have we experienced any work stoppages. We believe that relations with our employees are good.

Corporate information

     Arbutus Biopharma Corporation (“Arbutus”, “we”, “us”, and “our”) is a publicly traded industry-leading therapeutic solutions company focused on discovering, developing and commercializing a cure for patients suffering from chronic hepatitis HBV infection. Effective July 31, 2015, our corporate name changed from Tekmira Pharmaceuticals Corporation to Arbutus Biopharma Corporation. Also effective July 31, 2015, the corporate name of our wholly owned subsidiary, OnCore Biopharma, Inc. changed to Arbutus Biopharma, Inc. (“Arbutus Inc.”). We have two wholly owned subsidiaries:Arbutus Inc., and Protiva Biotherapeutics Inc. (“Protiva”). Unless stated otherwise or the context otherwise requires, references herein to “Arbutus”, “we”, “us” and “our” refer to Arbutus Biopharma Corporation, and, unless the context requires otherwise, one or more subsidiaries through which we conduct business.

Arbutus was incorporated pursuant to the British Columbia Business Corporations Act, or BCBCA, on October 6, 2005, and commenced active business on April 30, 2007, when Arbutus and its parent company, Inex Pharmaceuticals Corporation, or Inex, Inex, were reorganized under a statutory plan of arrangement (the Reorganization) completed under the provisions of the BCBCA. The Reorganization saw Inex’s entire business transferred to and continued by Arbutus.

On March 4, 2015, we completed a business combination pursuant to which OnCore Biopharma, Inc., or OnCore, became our wholly-owned subsidiary. This combined company intends to focus on developing a curative regimen for HBV patients by combining multiple therapeutic approaches.

Arbutus’ head office and principal place of business is located at 100-8900 Glenlyon Parkway, Burnaby, British Columbia, Canada, V5J 5J8 (telephone: (604) 419-3200). The Company’s registered and records office is located at 700 West Georgia St, 25th Floor, Vancouver, British Columbia, Canada, V7Y 1B3.

Item 1A. Risk Factors

Our business is subject to numerous risks. We caution you that the following important factors, among others, could cause our actual results to differ materially from those expressed in forward-looking statements made by us or on our behalf in filings with the SEC and Canadian securities regulators, press releases, communications with investors and oral statements. All statements other than statements relating to historical matters should be considered forward-looking statements. When used in this report, the words “believe,” “expect,” “plan,” “anticipate,” “estimate,” “predict,” “may” “could” “should,” “intend,” “will,” “target,” “goal” and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these words. Any or all of our forward-looking statements in this annual report on Form 10-K and in any other public statements we make may turn out to be wrong. They can be affected by inaccurate assumptions we might make or by known or unknown risks and uncertainties. Many factors mentioned in the discussion below will be important in determining future results. Consequently, no forward-looking statement can be guaranteed. Actual future results may vary materially from those anticipated in forward-looking statements. We explicitly disclaim any obligation to update any forward-looking statements to reflect events or circumstances that arise after the date hereof, unless required by law. You are advised, however, to consult any further disclosure we make in our reports filed with the SEC and Canadian securities regulators.

Risks Related to Our Business 

We are in the early stages of our development and because we have a short development history with ribonucleic acid interference (RNAi) and assets relating to HBV, there is a limited amount of information about us upon which you can evaluate our RNAi business and prospects, and our HBV business and prospects.

We have not begun to market or generate revenues from the commercialization of any RNAi products or our HBV products. We have only a limited history upon which one can evaluate our business and prospects as our therapeutic products are still at an early stage of development and thus we have limited experience and have not yet demonstrated an ability to successfully overcome many of the risks and uncertainties frequently encountered by companies in new and rapidly evolving fields, particularly in the biopharmaceutical area. For example, to execute our business plan, we will need to successfully: 

23




execute research and development activities using RNAi technology; and technologies involved in the development of HBV therapeutics;
build, maintain and protect a strong intellectual property portfolio;
gain acceptance for the development and commercialization of any product we develop;
develop and maintain successful strategic relationships; and
manage our spending and cash requirements as our expenses are expected to increase due to research and preclinical work, clinical trials, regulatory approvals, and commercialization and maintaining our intellectual property portfolio

If we are unsuccessful in accomplishing these objectives, we may not be able to develop products, raise capital, expand our business or continue our operations. The approach we are taking to discover and develop novel drug products is unproven and may never lead to marketable drug products.

     We intend to concentrate our internal research and development efforts in the future primarily on the discovery and development of therapeutics targeting chronic hepatitis B to be able to ultimately develop a cure for the disease. Our future success depends in part on the successful development of these therapeutics. Our approach to the treatment of HBV is unproven, and we do not know whether we will be able to develop any drugs of commercial value.

There is no known cure for HBV. Any compounds that we develop may not effectively address HBV persistence. Even if we are able to develop compounds that address one or more of these key factors, targeting these key factors has not been proven to cure HBV. We may be unable to acquire additional drug candidates on terms acceptable to us, or at all. Even if we are able to acquire or develop drug candidates that address one of these mechanisms of action in preclinical studies, we may not succeed in demonstrating safety and efficacy of the drug candidate in human clinical trials. If we are unable to identify suitable compounds for preclinical and clinical development, we will not succeed in realizing our goal of a cure for HBV.

We also intend to continue research and development efforts on RNAi technology and products based on RNAi technology. While RNAi technology is based on a naturally occurring process that takes place inside cells, which can suppress the production of specific proteins, and has the potential to generate therapeutic drugs that take advantage of that process, neither we nor any other company has received regulatory approval to market a therapeutic product based on RNAi technology. The scientific discoveries that form the basis for our efforts to discover and develop new products are relatively new. While there are a number of RNAi therapeutics in development, very few product candidates based on these discoveries have ever been tested in humans and there can be no assurance that any RNAi therapeutic product will be approved for commercial use.

If we are not successful in developing a product with our research and development efforts, we may be required to change the scope and direction of our product development activities. In that case, we may not be able to identify and implement successfully an alternative product development strategy.

We expect to depend in part on our existing collaborators for a significant portion of our revenues and to develop, conduct clinical trials with, obtain regulatory approvals for, and manufacture, market and sell some of our product candidates. If these collaborations are unsuccessful, or anticipated milestone payments are not received, our business could be adversely affected. 

We expect that we will depend in part on Alnylam, Spectrum, Dicerna, and Monsanto to provide revenue to fund our operations, especially in the near term. Furthermore, our strategy is to enter into various additional arrangements with corporate and academic collaborators, licensors, licensees and others for the research, development, clinical testing, manufacturing, marketing and commercialization of our products. We may be unable to continue to establish such collaborations, and any collaborative arrangements we do establish may be unsuccessful, or we may not receive milestone payments as anticipated.

Should any collaborative partner fail to develop or ultimately successfully commercialize any of the products to which it has obtained rights, our business may be adversely affected. In addition, once initiated, there can be no assurance that any of these collaborations will be continued or result in successfully commercialized products. Failure of a collaborative partner to continue funding any particular program could delay or halt the development or commercialization of any products arising out of such program. In addition, there can be no assurance that the collaborative partners will not pursue alternative technologies or develop alternative products either on their own or in collaboration with others, including our competitors, as a means for developing treatments for the diseases targeted by our programs.


24



We expect to spend substantial amounts to acquire additional drug candidates, to conduct further research and development and preclinical testing and clinical trials of our drug candidates, to seek regulatory approvals for our drug candidates and to launch and commercialize any drug candidates for which we receive regulatory approval. These expenditures will include costs associated with our and our subsidiary’s licensing agreements with Blumberg, or Drexel, and Cytos. Under the terms of these agreements, we are obligated to make significant cash payments upon the achievement of specified development, regulatory and sales performance milestones, as well as royalty payments in connection with the sale of licensed products, to our licensors.

We rely on third parties to conduct our clinical trials, and if they fail to fulfill their obligations, our development plans may be adversely affected.

We rely on independent clinical investigators, contract research organizations and other third-party service providers to assist us in managing, monitoring and otherwise carrying out our clinical trials. We have contracted with, and we plan to continue to contract with, certain third parties to provide certain services, including site selection, enrollment, monitoring and data management services. Although we depend heavily on these parties, we do not control them and therefore, we cannot be assured that these third parties will adequately perform all of their contractual obligations to us. If our third-party service providers cannot adequately fulfill their obligations to us on a timely and satisfactory basis or if the quality or accuracy of our clinical trial data is compromised due to failure to adhere to our protocols or regulatory requirements, or if such third parties otherwise fail to meet deadlines, our development plans may be delayed or terminated.

We have no sales, marketing or distribution experience and would have to invest significant financial and management resources to establish these capabilities.

We have no sales, marketing or distribution experience. We currently expect to rely heavily on third parties to launch and market certain of our products, if approved. However, if we elect to develop internal sales, distribution and marketing capabilities, we will need to invest significant financial and management resources. For products where we decide to perform sales, marketing and distribution functions ourselves, we could face a number of additional risks, including: 

we may not be able to attract and build a significant marketing or sales force;
the cost of establishing a marketing or sales force may not be justifiable in light of the revenues generated by any particular product; and
our direct sales and marketing efforts may not be successful.

If we are unable to develop our own sales, marketing and distribution capabilities, we will not be able to successfully commercialize our products, if approved, without reliance on third parties.

We will rely on third-party manufacturers to manufacture our products (if approved) in commercial quantities, which could delay, prevent or increase the costs associated with the future commercialization of our products.

Our product candidates have not yet been manufactured for commercial use. If any of our product candidates become approved for commercial sale, in order to supply our or our collaborators’ commercial requirements for such an approved product, we will need to establish third-party manufacturing capacity. Any third-party manufacturing partner may be required to fund capital improvements to support the scale-up of manufacturing and related activities. The third-party manufacturer may not be able to establish scaled manufacturing capacity for an approved product in a timely or economic manner, if at all. If a manufacturer is unable to provide commercial quantities of such an approved product, we will have to successfully transfer manufacturing technology to a new manufacturer. Engaging a new manufacturer for such an approved product could require us to conduct comparative studies or utilize other means to determine bioequivalence of the new and prior manufacturers’ products, which could delay or prevent our ability to commercialize such an approved product. If any of these manufacturers is unable or unwilling to increase its manufacturing capacity or if we are unable to establish alternative arrangements on a timely basis or on acceptable terms, the development and commercialization of such an approved product may be delayed or there may be a shortage in supply. Any inability to manufacture our products in sufficient quantities when needed would seriously harm our business.


25



Manufacturers of our approved products, if any, must comply with current good manufacturing practices (cGMP) requirements enforced by the FDA and Health Canada through facilities inspection programs. These requirements include quality control, quality assurance, and the maintenance of records and documentation. Manufacturers of our approved products, if any, may be unable to comply with these cGMP requirements and with other FDA, Health Canada, state, and foreign regulatory requirements. We have little control over our manufacturers’ compliance with these regulations and standards. A failure to comply with these requirements may result in fines and civil penalties, suspension of production, suspension or delay in product approval, product seizure or recall, or withdrawal of product approval. If the safety of any quantities supplied is compromised due to our manufacturer’s failure to adhere to applicable laws or for other reasons, we may not be able to obtain regulatory approval for or successfully commercialize our products, which would seriously harm our business.  

Risks Related to Our Financial Results and Need for Financing

We will require substantial additional capital to fund our operations. If additional capital is not available, we may need to delay, limit or eliminate our research, development and commercialization processes and may need to undertake a restructuring.

Within the next several years, substantial additional funds will be required to continue with the active development of our pipeline products and technologies. In particular, our funding needs may vary depending on a number of factors including:

revenues earned from our partners, including Alnylam, Acuitas, Spectrum, Monsanto, and Dicerna;
the extent to which we continue the development of our product candidates or form collaborative relationships to advance our products;
our decisions to in-license or acquire additional products or technology for development,
our ability to attract and retain corporate partners, and their effectiveness in carrying out the development and ultimate commercialization of our product candidates;
whether batches of drugs that we manufacture fail to meet specifications resulting in delays and investigational and remanufacturing costs;
the decisions, and the timing of decisions, made by health regulatory agencies regarding our technology and products;
competing technological and market developments; and
prosecuting and enforcing our patent claims and other intellectual property rights.

We will seek to obtain funding to maintain and advance our business from a variety of sources including public or private equity or debt financing, collaborative arrangements with pharmaceutical and biotechnology companies and government grants and contracts. There can be no assurance that funding will be available at all or on acceptable terms to permit further development of our products especially in light of the current difficult climate for investment in biotechnology companies.

If adequate funding is not available, we may be required to delay, reduce or eliminate one or more of our research or development programs or reduce expenses associated with non-core activities. We may need to obtain funds through arrangements with collaborators or others that may require us to relinquish most or all of our rights to product candidates at an earlier stage of development or on less favorable terms than we would otherwise seek if we were better funded. Insufficient financing may also mean failing to prosecute our patents or relinquishing rights to some of our technologies that we would otherwise develop or commercialize.

We have incurred losses in nearly every year since our inception and we anticipate that we will not achieve sustained profits for the foreseeable future. To date, we have had no product revenues.

With the exception of the year ended December 31, 2006 and December 31, 2012, we have incurred losses each fiscal year since inception until December 31, 2015 and have not received any revenues other than from research and development collaborations, license fees and milestone payments. From inception to December 31, 2015, we have an accumulated net deficit of $ 267.0 million. As we continue our research and development and clinical trials and seek regulatory approval for the sale of our product candidates, we do not expect to attain sustained profitability for the foreseeable future. We do not expect to achieve sustained profits until such time as strategic alliance payments, product sales and royalty payments, if any, generate sufficient revenues to fund our continuing operations. We cannot predict if we will ever achieve profitability and, if we do, we may not be able to remain consistently profitable or increase our profitability.

We are subject to risks associated with currency fluctuations, and changes in foreign currency exchange rates could impact our results of operations.

26




Prior to January 1, 2016, our functional currency was the Canadian dollar. On January 1, 2016, our functional currency changed from the Canadian dollar to the U.S. dollar based on our analysis of the changes in the primary economic environment in which we operate. As a result, changes in the exchange rate between the Canadian dollar and the U.S. dollar could materially impact our reported results of operations and distort period to period comparisons. In particular, to the extent that foreign currency-denominated (i.e., non-U.S. dollar) monetary assets do not equal the amount of our foreign currency denominated monetary liabilities, foreign currency gains or losses could arise and materially impact our financial statements. As a result of such foreign currency fluctuations, it could be more difficult to detect underlying trends in our business and results of operations. In addition, to the extent that fluctuations in currency exchange rates cause our results of operations to differ from our expectations or the expectations of our investors, the trading price of our common shares could be adversely affected.

From time to time, we may engage in exchange rate hedging activities in an effort to mitigate the impact of exchange rate fluctuations. Any hedging technique we implement may fail to be effective. If our hedging activities are not effective, changes in currency exchange rates may have a more significant impact on the trading price of our common shares.

Risks Related to Managing Our Operations

If we are unable to attract and retain qualified key management, scientific staff, consultants and advisors, our ability to implement our business plan may be adversely affected.

We depend upon our senior executive officers as well as key scientific, management and other personnel. The competition for qualified personnel in the biotechnology field is intense. We rely heavily on our ability to attract and retain qualified managerial, scientific and technical staff. The loss of the service of any of the members of our senior management, including Dr. Mark Murray, our President and Chief Executive Officer, may adversely affect our ability to develop our technology, add to our pipeline, advance our product candidates and manage our operations.

We may have difficulty managing our growth and expanding our operations successfully as we seek to evolve from a company primarily involved in discovery and preclinical testing into one that develops products through clinical development and commercialization. 

As product candidates we develop enter and advance through clinical trials, we will need to expand our development, regulatory, manufacturing, clinical and medical capabilities or contract with other organizations to provide these capabilities for us. As our operations expand, we expect that we will need to manage additional relationships with various collaborators, suppliers and other organizations. Our ability to manage our operations and growth will require us to continue to improve our operational, financial and management controls, reporting systems and procedures. We may not be able to implement improvements to our management information and control systems in an efficient or timely manner and may discover deficiencies in existing systems or controls.

Additionally, our success will also depend on ability to continue to realize the benefits of our merger with OnCore, and Arbutus can offer no assurance that we will continue to realize benefits anticipated to result from the merger.

We could face liability from our controlled use of hazardous and radioactive materials in our research and development processes. 

We use certain radioactive materials, biological materials and chemicals, including organic solvents, acids and gases stored under pressure, in our research and development activities. Our use of radioactive materials is regulated by the Canadian Nuclear Safety Commission for the possession, transfer, import, export, use, storage, handling and disposal of radioactive materials. Our use of biological materials and chemicals, including the use, manufacture, storage, handling and disposal of such materials and certain waste products is regulated by a number of federal, provincial and local laws and regulations. Although we believe that our safety procedures for handling such materials comply with the standards prescribed by such laws and regulations, the risk of accidental contamination or injury from these materials cannot be completely eliminated. In the event of such an accident, we could be held liable for any damages that result and any such liability could exceed our resources. We are not specifically insured with respect to this liability. 

Our business and operations could suffer in the event of information technology system failures.


27



Despite the implementation of security measures, our internal computer systems and those of our contractors and consultants are vulnerable to damage from computer viruses, unauthorized access, natural disasters, terrorism, war, and telecommunication and electrical failures. Such events could cause interruption of our operations. For example, the loss of pre-clinical trial data or data from completed or ongoing clinical trials for our product candidates could result in delays in our regulatory filings and development efforts and significantly increase our costs. To the extent that any disruption or security breach will result in a loss of or damage to our data, or inappropriate disclosure of confidential or proprietary information, we could incur liability and the development of our product candidates could be delayed.

If, in the future, our internal control over financial reporting is not effective, it could have a material adverse effect on our stock price and our ability to raise capital. 

We have completed an independent audit of our internal control over financial reporting for our fiscal year ending December 31, 2015 and no material weaknesses have been identified. If our internal control over financial reporting is determined in the future to not be effective, whether by our management or by our independent auditors, there could be an adverse reaction in the financial markets due to a loss of confidence in the reliability of our financial statements, which could materially adversely affect our stock price and our ability to raise capital necessary to operate our business. In addition, we may be required to incur costs in improving our internal control system and hiring additional personnel.

We rely on and will incur additional expense in connection with our research collaboration with Blumberg.

In October 2014, Arbutus Inc. entered into an agreement with Blumberg under which Arbutus Inc.will provide annual funding for a three year period in the amount of $1.0 million per year and which is renewable for an additional three year period at our option, for Blumberg to conduct research projects in HBV and liver cancer pursuant to a research plan to be agreed upon by the parties. In exchange, Arbutus Inc.has the right to obtain an exclusive, royalty bearing, worldwide license to intellectual property generated by Blumberg in the course of the funded research and we believe that Blumberg’s HBV research platform will continue to be a source of potentially novel hepatitis B targets, drug candidates, assays and other HBV specific technologies. As a result, we are dependent, in part, upon the success of Blumberg in performing its responsibilities under this research collaboration. Blumberg may not cooperate with us or perform its obligations under the agreement. We cannot control the amount and timing of Blumberg’s resources that will be devoted to research and development activities related to our research collaboration. Further, development costs associated with our research projects may be difficult to anticipate and exceed our expectations. If funding is unable to continue to financially support the collaboration, if we do not obtain exclusive licenses from Blumberg to the resulting intellectual property, or if we fails to comply with our obligations under those license agreements, its development efforts may be materially harmed.

Risks Related to Development, Clinical Testing and Regulatory Approval of Our Product Candidates

The manufacture and sale of human therapeutic products are governed by a variety of statutes and regulations. There can be no assurance that our product candidates will obtain regulatory approval. 

To obtain marketing approval, U.S. and Canadian laws require: 

controlled research and human clinical testing;
establishment of the safety and efficacy of the product for each use sought;
government review and approval of a submission containing manufacturing, pre-clinical and clinical data;
adherence to Good Manufacturing Practice Regulations during production and storage; and
control of marketing activities, including advertising and labelling

The product candidates we currently have under development will require significant development, preclinical and clinical testing and investment of significant funds before their commercialization.  Some of our product candidates, if approved, will require the completion of post-market studies. There can be no assurance that such products will be developed. The process of completing clinical testing and obtaining required approvals is likely to take a number of years and require the use of substantial resources. If we fail to obtain regulatory approvals, our operations will be adversely affected. Further, there can be no assurance that product candidates employing a new technology will be shown to be safe and effective in clinical trials or receive applicable regulatory approvals.

Other markets have regulations and restrictions similar to those in the U.S. and Canada. Investors should be aware of the risks, problems, delays, expenses and difficulties which we may encounter in view of the extensive regulatory environment which affects our business in any jurisdiction where we develop product candidates.


28



If testing of a particular product candidate does not yield successful results, then we will be unable to commercialize that product candidate. 

We must demonstrate our product candidates’ safety and efficacy in humans through extensive clinical testing. Our research and development programs are at an early stage of development. We may experience numerous unforeseen events during, or as a result of, the testing process that could delay or prevent commercialization of any products, including the following: 

decreased demand for our product candidates;
impairment of our business reputation;
withdrawal of clinical trial participants;
costs of related litigation;
substantial monetary awards to patients or other claimants;
loss of revenues; and
inability to commercialize our product candidates.

Although we currently have product liability insurance coverage for our clinical trials for expenses or losses, our insurance coverage is limited to $10 million per occurrence, and $10 million in the aggregate, and may not reimburse us or may not be sufficient to reimburse us for any or all expenses or losses we may suffer. Moreover, insurance coverage is becoming increasingly expensive and, in the future, we may not be able to maintain insurance coverage at a reasonable cost or in sufficient amounts to protect us against losses due to liability. We intend to expand our insurance coverage to include the sale of commercial products if we obtain marketing approval for our product candidates in development, but we may be unable to obtain commercially reasonable product liability insurance for any products approved for marketing. On occasion, large judgments have been awarded in class action lawsuits based on products that had unanticipated side effects. A successful product liability claim or series of claims brought against us could cause our stock price to fall and, if judgments exceed our insurance coverage, could decrease our cash and adversely affect our business.

Recently enacted and future legislation may increase the difficulty and cost for us to obtain marketing approval of and commercialize our drug candidates and affect the prices we may obtain. 

In the United States and some foreign jurisdictions, there have been a number of legislative and regulatory changes and proposed changes regarding the healthcare system that could, among other things, prevent or delay marketing approval of our drug candidates, restrict or regulate post approval activities and affect our ability to profitably sell any products for which we obtain marketing approval.

For example, in March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care Education Reconciliation Act, or collectively the Affordable Care Act, was enacted to broaden access to health insurance, reduce or constrain the growth of healthcare spending, enhance remedies against fraud and abuse, add new transparency requirements for health care and health insurance industries, impose new taxes and fees on the health industry and impose additional health policy reforms. Although it is too early to determine the effect of the Affordable Care Act, the new law appears likely to continue the downward pressure on pharmaceutical pricing, especially under the Medicare program, and may also increase our regulatory burdens and operating costs.

Moreover, the recently enacted Drug Supply Chain Security Act imposes new obligations on manufacturers of pharmaceutical products related to product and tracking and tracing. Legislative and regulatory proposals have been made to expand post approval requirements and restrict sales and promotional activities for pharmaceutical products. We are not sure whether additional legislative changes will be enacted, or whether the current regulations, guidance or interpretations will be changed, or what the impact of such changes on our business, if any, may be.

Coverage and adequate reimbursement may not be available for our drug candidates, which could make it difficult for us to sell our products profitably.

Market acceptance and sales of any drug candidates that we develop, will depend in part on the extent to which reimbursement for these products and related treatments will be available from third party payors, including government health administration authorities and private health insurers. Third party payors decide which drugs they will pay for and establish reimbursement levels. Third party payors often rely upon Medicare coverage policy and payment limitations in setting their own reimbursement policies. However, decisions regarding the extent of coverage and amount of reimbursement to be provided for each of our drug candidates will be made on a plan by plan basis. One payors determination to provide coverage for a product does not assure that other payors will also provide coverage, and adequate reimbursement, for the product.

29



Additionally, a third party payors decision to provide coverage for a drug does not imply that an adequate reimbursement rate will be approved. Each plan determines whether or not it will provide coverage for a drug, what amount it will pay the manufacturer for the drug, and on what tier of its formulary the drug will be placed. The position of a drug on a formulary generally determines the copayment that a patient will need to make to obtain the drug and can strongly influence the adoption of a drug by patients and physicians. Patients who are prescribed treatments for their conditions and providers performing the prescribed services generally rely on third party payors to reimburse all or part of the associated healthcare costs. Patients are unlikely to use our products unless coverage is provided and reimbursement is adequate to cover a significant portion of the cost of our products. 

A primary trend in the U.S. healthcare industry and elsewhere is cost containment. Third party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular medications. We cannot be sure that coverage and reimbursement will be available for any product that we commercialize and, if reimbursement is available, what the level of reimbursement will be. Inadequate coverage and reimbursement may impact the demand for, or the price of, any product for which we obtain marketing approval. If coverage and adequate reimbursement is not available, or is available only to limited levels, we may not be able to successfully commercialize any drug candidates that we develop.

Additionally, there have been a number of legislative and regulatory proposals to change the healthcare system in the United States and in some foreign jurisdictions that could affect our ability to sell any future drugs profitably. These legislative and regulatory changes may negatively impact the reimbursement for any future drugs, following approval.

Risks Related to Patents, Licenses and Trade Secrets

Other companies or organizations may assert patent rights that prevent us from developing or commercializing our products. 

RNA interference is a relatively new scientific field that has generated many different patent applications from organizations and individuals seeking to obtain patents in the field. These applications claim many different methods, compositions and processes relating to the discovery, development and commercialization of RNAi therapeutic products. Because the field is so new, very few of these patent applications have been fully processed by government patent offices around the world, and there is a great deal of uncertainty about which patents will be issued, when, to whom, and with what claims. It is likely that there could be litigation and other proceedings, such as interference and opposition proceedings in various patent offices, relating to patent rights in RNAi.

In addition, there are many issued and pending patents that claim aspects of RNAi trigger chemistry technology that we may need to apply to our product candidates. There are also many issued patents that claim genes or portions of genes that may be relevant for RNAi trigger drug products we wish to develop. Thus, it is possible that one or more organizations will hold patent rights to which we will need a license. If those organizations refuse to grant us a license to such patent rights on reasonable terms, we will not be able to market products or perform research and development or other activities covered by these patents.

Our patents and patent applications may be challenged and may be found to be invalid, which could adversely affect our business.

Certain Canadian, U.S. and international patents and patent applications we own involve complex legal and factual questions for which important legal principles are largely unresolved. For example, no consistent policy has emerged for the breadth of biotechnology patent claims that are granted by the U.S. Patent and Trademark Office or enforced by the U.S. federal courts. In addition, the coverage claimed in a patent application can be significantly reduced before a patent is issued. Also, we face the following intellectual property risks: 

some or all patent applications may not result in the issuance of a patent;
patents issued may not provide the holder with any competitive advantages;
patents could be challenged by third parties;
the patents of others, including Alnylam, could impede our ability to do business;
competitors may find ways to design around our patents; and
competitors could independently develop products which duplicate our products.


30



A number of industry competitors and institutions have developed technologies, filed patent applications or received patents on various technologies that may be related to or affect our business. Some of these technologies, applications or patents may conflict with our technologies or patent applications. Such conflict could limit the scope of the patents, if any, that we may be able to obtain or result in the denial of our patent applications. In addition, if patents that cover our activities are issued to other companies, there can be no assurance that we would be able to obtain licenses to these patents at a reasonable cost or be able to develop or obtain alternative technology. If we do not obtain such licenses, we could encounter delays in the introduction of products, or could find that the development, manufacture or sale of products requiring such licenses is prohibited. In addition, we could incur substantial costs in defending patent infringement suits brought against us or in filing suits against others to have such patents declared invalid. As publication of discoveries in the scientific or patent literature often lags behind actual discoveries, we cannot be certain we or any licensor was the first creator of inventions covered by pending patent applications or that we or such licensor was the first to file patent applications for such inventions. Any future proceedings could result in substantial costs, even if the eventual outcomes are favorable. There can be no assurance that our patents, if issued, will be held valid or enforceable by a court or that a competitor’s technology or product would be found to infringe such patents.

Our business depends, in part, on our ability to use RNAi technology that we have licensed or will in the future license from third parties, including Alnylam, and, if these licenses were terminated or if we were unable to license additional technology we may need in the future, our business will be adversely affected.

We currently hold licenses for certain technologies that are or may be applicable to our current and subsequent product candidates. These include a license to patents held or applied for by Alnylam and a license to UNA technology from Arcturus Therapeutics. The licenses are subject to termination in the event of a breach by us of the license, if we fail to cure the breach following notice and the passage of a cure period. The UBC license, which is sublicensed to Alnylam, is subject to termination with respect to one or more particular patents if we and Alnylam were to cease patent prosecution or maintenance activities with respect to such patent(s), or in the event of a breach by us of the license, if we fail to cure the breach following notice and the passage of a cure period. There can be no assurance that these licenses will not be terminated. We may need to acquire additional licenses in the future to technologies developed by others, including Alnylam. For example, Alnylam has granted us a worldwide license for the discovery, development and commercialization of RNAi products directed to thirteen gene targets (three exclusive and ten non-exclusive licenses). Licenses for the five non-exclusive targets and one exclusive target have already been granted. We have rights to select the gene targets for up to two more exclusive licenses and five more nonexclusive licenses from Alnylam, which would be made available to us only if they have not been previously selected by Alnylam or one of its other partners. This will limit the targets available for selection by us, and we may never be able to select gene targets or may be required to make our selection from gene targets that have minimal commercial potential. Furthermore, future license agreements may require us to make substantial milestone payments. We will also be obligated to make royalty payments on the sales, if any, of products resulting from licensed RNAi technology. For some of our licensed RNAi technology, we are responsible for the costs of filing and prosecuting patent applications. The termination of a license or the inability to license future technologies on acceptable terms may adversely affect our ability to develop or sell our products.

Our business depends, in part, on our ability to use the technology that we have licensed or will in the future license from third parties, including Blumberg, and Cytos, and, if these licenses were terminated or if we were unable to license additional technology we may need in the future, our business will be adversely affected.

We have licensed certain of our intellectual property from Blumberg and Cytos. Our current technology licenses are critical to our business and we expect to enter into additional licenses in the future.  If we fail to comply with our obligations under these agreements or any future license agreements, we are subject to a bankruptcy, or if we grant a sublicense in the future and our sublicense does not comply with our obligations under these agreements or becomes subject to a bankruptcy, the licensor may have the right to terminate the license, in which event we would not be able to develop or market products covered by the license or may face other penalties under the agreements, which would have a materially adverse effect on our business. In addition, applicable laws involving bankruptcy or similar proceeding by licensors in some jurisdictions outside the United States may provide the trustee or receiver in such proceeding with the right to set aside or otherwise terminate or seek to modify the license. Any termination of these agreements or reduction or elimination of our rights under these agreements may result in our having to negotiate new or amended agreements with less favorable terms, or cause us to lose our rights under these agreements, including our rights to important intellectual property and technologies that form the basis of our technology, which may then be in licensed by one or more of our competitors.

We may incur substantial costs as a result of litigation or other proceedings relating to patent and other intellectual property rights which could have a material adverse effect on our business, financial condition and results of operations and could cause the market value of our Common Shares to decline.


31



There has been significant litigation in the biotechnology industry over contractual obligations, patents and other proprietary rights, and we may become involved in various types of litigation that arise from time to time. Involvement in litigation could consume a substantial portion of our resources, regardless of the outcome of the litigation. Counterparties in litigation may be better able to sustain the costs of litigation because they have substantially greater resources. If claims against us are successful, in addition to any potential liability for damages, we could be required to obtain a license, grant cross-licenses, and pay substantial milestones or royalties in order to continue to develop, manufacture or market the affected products. Involvement and continuation of involvement in litigation may result in significant and unsustainable expense, and divert management’s attention from ongoing business concerns and interfere with our normal operations. Litigation is also inherently uncertain with respect to the time and expenses associated therewith, and involves risks and uncertainties in the litigation process itself, such as discovery of new evidence or acceptance of unanticipated or novel legal theories, changes in interpretation of the law due to decisions in other cases, the inherent difficulty in predicting the decisions of judges and juries and the possibility of appeals. Ultimately we could be prevented from commercializing a product or be forced to cease some aspect of our business operations as a result of claims of patent infringement or violation of other intellectual property rights and the costs associated with litigation, which could have a material adverse effect on our business, financial condition, and operating results and could cause the market value of our Common Shares to decline.

Confidentiality agreements with employees and others, including collaborators, may not adequately prevent disclosure of trade secrets and other proprietary information.

Much of our know-how and technology may constitute trade secrets. There can be no assurance, however, that we will be able to meaningfully protect our trade secrets. In order to protect our proprietary technology and processes, we rely in part on confidentiality agreements with our collaborators, employees, vendors, consultants, outside scientific collaborators and sponsored researchers, and other advisors. These agreements may not effectively prevent disclosure of confidential information and may not provide an adequate remedy in the event of unauthorized disclosure of confidential information. In addition, others may independently discover trade secrets and proprietary information, and in such cases we could not assert any trade secret rights against such party. Costly and time consuming litigation could continue to be necessary to enforce and determine the scope of our proprietary rights, and failure to obtain or maintain trade secret protection could adversely affect our competitive business position.

We have licensed critical portions of our intellectual property from Blumberg and Drexel, and are subject to significant obligations under those license agreements.

The rights we hold under our license agreements with Blumberg and Drexel are are important to our business. Our discovery and development platform is built, in part, around patents exclusively in licensed from these parties. For example, the elimination of cccDNA is the most critical element in our combination strategy to cure HBV, and the cccDNA formation inhibitor program is in licensed from Blumberg and Drexel.

We have licenses with Blumberg and Drexel, both directly and through its acquisition of Enantigen, that grant us the exclusive (except in some cases as to know how that is not unique or specific to the licensed products or compound series, which are non-exclusive and subject to retained rights for non-commercial research use), worldwide license to make, have made, use, import, offer for sale and sell products incorporating one or more licensed compounds, which include cccDNA inhibitors, capsid assembly inhibitors, inhibitors of secretion of HBV antigens and hepatocellular carcinoma inhibitors, either for general use in humans or for use in the field of HBV research, diagnosis and treatment. Our license with Cytos grants us the exclusive, worldwide, sub licensable (subject to certain restrictions with respect to licensed viral infections other than hepatitis) license, under patents and know-how controlled by Cytos, to research, develop, manufacture and commercialize, for the diagnosis, treatment or prevention of hepatitis viruses in humans, licensed products that incorporate Q beta-derived virus-like particles that are filled with TLR9, TLR7 or RIG-I agonists.


32



Under our agreements with Blumberg, Drexel and Cytos, we are subject to significant obligations, including diligence obligations with respect to development and commercialization activities, payment obligations upon achievement of certain milestones and royalties on product sales, as well as other material obligations. Under our direct agreement with Blumberg and Drexel, we agreed to pay up to $3.5 million in development and regulatory milestones per licensed compound series, up to $92.5 million in sales performance milestones per licensed product, and royalties in the mid-single digits in connection with the sale of licensed products. Under each of the three license agreements that our subsidiary, Enantigen, has with Blumberg and Drexel, we are obligated to pay up to $500,000 in development and regulatory milestones per licensed product and royalties in the low single digits in connection with the sale of licensed products. Under our agreement with Cytos, we agreed to pay up to $67 million upon the achievement of specified development and regulatory milestones for hepatitis and each additional licensed viral infection, in each case for each of the six licensed compound series, up to $110 million upon the achievement of specified sales performance milestones, and tiered royalty payments at a royalty rate in the high-single to low double digits, based upon net sales of licensed products. If these payments become due under the terms of the agreements, we may be negatively affected.

If there is any conflict, dispute, disagreement or issue of non-performance between us and Blumberg, Drexel, or Cytos regarding our rights or obligations under these license agreements, including any conflict, dispute or disagreement arising from our failure to satisfy diligence or payment obligations under such agreements, Blumberg and Drexel or Cytos, as applicable, may have a right to terminate the license. The loss of any of these license agreements could materially and adversely affect our ability to use intellectual property that is critical to our drug discovery and development efforts, as well as its ability to enter into future collaboration, licensing and/or marketing agreements for one or more affected drug candidates or development programs.

Some of our licensors have retained rights to develop and commercialize certain of our drug candidates to treat diseases other than HBV and, as a result, our development and commercialization efforts may be negatively affected.

Our license agreements provide us with the rights to develop and commercialize our drug candidates for HBV; however, some of our licensors have retained rights to develop and commercialize certain of its drug candidates to treat diseases other than HBV, and to license those rights to other third parties. For example, Cytos has retained all rights with respect to development of the licensed products for influenza, all non-viral infections and certain viral infections other than hepatitis.

If we obtain regulatory approval for our TLR9 agonist for HBV and Cytos obtains regulatory approval for a drug candidate that has the same active ingredient as our TLR9 agonist for another indication, and if each is available outside of a combination therapy, physicians may prescribe the Cytos drug, instead of our drug, to patients with HBV if, for example, the cost of the Cytos drug is less than our drug. In this case, we would not be receiving any payments on the account of such sales and our revenue would be adversely affected.

Risks Related to Competition

The pharmaceutical market is intensely competitive. If we are unable to compete effectively with existing drugs, new treatment methods and new technologies, we may be unable to successfully commercialize any product candidates that we develop. 

The pharmaceutical market is intensely competitive and rapidly changing. Many large pharmaceutical and biotechnology companies, academic institutions, governmental agencies and other public and private research organizations are pursuing the development of novel drugs for the same diseases that we are targeting or expect to target. Many of our competitors have: 

much greater financial, technical and human resources than we have at every stage of the discovery, development, manufacture and commercialization process;
more extensive experience in pre-clinical testing, conducting clinical trials, obtaining regulatory approvals, and in manufacturing, marketing and selling pharmaceutical products;
product candidates that are based on previously tested or accepted technologies;
products that have been approved or are in late stages of development; and
collaborative arrangements in our target markets with leading companies and research institutions.


33



We will face intense competition from products that have already been approved and accepted by the medical community for the treatment of the conditions for which we are currently developing products. We also expect to face competition from new products that enter the market. We believe a significant number of products are currently under development, and may become commercially available in the future, for the treatment of conditions for which we may try to develop products. These products, or other of our competitors’ products, may be more effective, safer, less expensive or marketed and sold more effectively, than any products we develop.

We are aware of several companies that are working to develop drugs that would compete against our drug candidates for HBV treatment. As a significant unmet medical need exists for HBV, there are several large and small pharmaceutical companies focused on delivering therapeutics for treatment of HBV. Further, it is likely that additional drugs will become available in the future for the treatment of HBV. We will face competition from other drugs currently approved or that will be approved in the future for the treatment of chronic hepatitis B.

We anticipate significant competition in the HBV market with several early phase product candidates announced. We will also face competition for other product candidates that we expect to develop in the future.

If we successfully develop product candidates, and obtain approval for them, we will face competition based on many different factors, including the following: 

safety and effectiveness of our products
ease with which our products can be administered and the extent to which patients and physicians accept new routes of administration;
timing and scope of regulatory approvals for these products;
availability and cost of manufacturing, marketing and sales capabilities;
price;
reimbursement coverage; and
patent position.

Our competitors may develop or commercialize products with significant advantages over any products we develop based on any of the factors listed above or on other factors. Our competitors may therefore be more successful in commercializing their products than we are which could adversely affect our competitive position and business. Competitive products may make any products we develop obsolete or uncompetitive before we can recover the expenses of developing and commercializing our product candidates. Such competitors could also recruit our employees, which could negatively impact our level of expertise and the ability to execute on our business plan. Furthermore, we also face competition from existing and new treatment methods that reduce or eliminate the need for drugs, such as the use of advanced medical devices. The development of new medical devices or other treatment methods for the diseases we are targeting and may target could make our product candidates non-competitive, obsolete or uneconomical.

We face competition from other companies that are working to develop novel products using technology similar to ours. If these companies develop products more rapidly than we do or their technologies, including delivery technologies, are more effective than ours, then our ability to successfully commercialize products will be adversely affected.

We face significant competition from other biotechnology and pharmaceutical companies targeting HBV.

As a significant unmet medical need exists for HBV, there are several large and small pharmaceutical companies focused on delivering therapeutics for treatment of HBV. These companies include Johnson and Johnson, Gilead Sciences, Roche Holding AG, Arrowhead Research, GlaxoSmithKline/Ionis Pharmaceuticals, Alnylam Pharmaceuticals, Assembly Biosciences, Bristol-Myers Squibb, Spring Bank Pharmaceuticals, Replicor, and ContraVir Pharmaceuticals. Further, it is likely that additional drugs will become available in the future for the treatment of HBV.

We are aware of several companies that are working to develop drugs that would compete against our drug candidates for HBV treatment. Many of our existing or potential competitors have substantially greater financial, technical and human resources than we do and significantly greater experience in the discovery and development of drug candidates, as well as in obtaining regulatory approvals of those drug candidates in the United States and in foreign countries. Our current and potential future competitors also have significantly more experience commercializing drugs that have been approved for marketing. Mergers and acquisitions in the pharmaceutical and biotechnology industries could result in even more resources being concentrated among a small number of our competitors.


34



Competition may increase further as a result of advances in the commercial applicability of technologies and greater availability of capital for investment in these industries. Our competitors may succeed in developing, acquiring or licensing, on an exclusive basis, drug candidates that are more effective or less costly than any drug candidate that we may develop.

We will face competition from other drugs currently approved or that will be approved in the future for the treatment of HBV. Therefore, our ability to compete successfully will depend largely on our ability to: 

discover, develop and commercialize drugs that are superior to other products in the market;
demonstrate through our clinical trials that our drug candidates are differentiated from existing and future therapies;
attract qualified scientific, product development and commercial personnel;
obtain patent or other proprietary protection for our drugs and technologies;
obtain required regulatory approvals;
successfully collaborate with pharmaceutical companies in the discovery, development and commercialization of new drugs; and
negotiate competitive pricing and reimbursement with third party payors.

The availability of our competitors’ products could limit the demand, and the price we are able to charge, for any drug candidate we develop. The inability to compete with existing or subsequently introduced drug candidates would have a material adverse impact on our business, financial condition and prospects.

Established pharmaceutical companies may invest heavily to accelerate discovery and development of novel compounds or to in license novel compounds that could make our drug candidates less competitive. In addition, any new product that competes with an approved product must demonstrate compelling advantages in efficacy, convenience, tolerability and safety in order to overcome price competition and to be commercially successful. Accordingly, our competitors may succeed in obtaining patent protection, discovering, developing or receiving FDA approval for or commercializing medicines before we do, which would have a material adverse impact on our business.

Risks Related to the Ownership of our Common Shares

If our stock price fluctuates, our investors could incur substantial losses.

The market price of our Common Shares may fluctuate significantly in response to factors that are beyond our control. The stock market in general has recently experienced extreme price and volume fluctuations. The market prices of securities of pharmaceutical and biotechnology companies have been extremely volatile, and have experienced fluctuations that often have been unrelated or disproportionate to the operating performance of these companies. These broad market fluctuations could result in extreme fluctuations in the price of our Common Shares, which could cause our investors to incur substantial losses.

There is no assurance that an active trading market in our Common Shares will be sustained.

Our Common Shares are listed for trading on the NASDAQ exchange. However, there can be no assurances that an active trading market in our Common Shares on these stock exchanges will be sustained.

We are incorporated in Canada and the majority of our assets, and some of our officers reside outside the United States, with the result that it may be difficult for investors to enforce any judgments obtained against us or some of our officers.

Arbutus, and some of its subsidiaries, are incorporated under the laws of the Province of British Columbia and the majority of Arbutus' assets are located outside the United States. While we have appointed National Registered Agents, Inc. as our agent for service of process to effect service of process within the United States upon us, it may not be possible for you to enforce against us or those persons in the United States, judgments obtained in U.S. courts based upon the civil liability provisions of the U.S. federal securities laws or other laws of the United States. In addition, there is doubt as to whether original action could be brought in Canada against us or our directors or officers based solely upon U.S. federal or state securities laws and as to the enforceability in Canadian courts of judgments of U.S. courts obtained in actions based upon the civil liability provisions of U.S. federal or state securities laws.

If we are deemed to be a “passive foreign investment company” for the current or any future taxable year, investors who are subject to United States federal taxation would likely suffer materially adverse U.S. federal income tax consequences.


35



We generally will be a “passive foreign investment company” under the meaning of Section 1297 of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), (a “PFIC”) if (a) 75% or more of our gross income is “passive income” (generally, dividends, interest, rents, royalties, and gains from the disposition of assets producing passive income) in any taxable year, or (b) if at least 50% or more of the quarterly average value of our assets produce, or are held for the production of, passive income in any taxable year. A shareholder who is a U.S. person (as such term is defined under applicable U.S. legislation) should be aware that we believe that we were a PFIC during one or more prior taxable years.  We have not yet made a determination as to whether we were a PFIC in respect of our taxable year ended December 31, 2015.  If we are a PFIC for any taxable year during which a U.S. person holds our Common Shares, it would likely result in materially adverse U.S. federal income tax consequences for such U.S. person, including, but not limited to, any gain from the sale of our Common Shares would be taxed as ordinary income, as opposed to capital gain, and such gain and certain distributions on our Common Shares would be subject to an interest charge, except in certain circumstances. It may be possible for U.S. persons to fully or partially mitigate such tax consequences by making a “qualifying electing fund election,” as defined in the Code (a “QEF Election”), but there is no assurance that we will provide such persons with the information that we are required to provide to them in order to assist them in making a QEF Election.  In addition, U.S. persons that hold Common Shares issuable upon exercise of warrants are generally not eligible to make certain elections available under the Code that are intended to mitigate the adverse tax consequences of PFIC rules with respect to such warrant shares unless such holders also elect to make a deemed taxable sale of their warrant shares. The PFIC rules are extremely complex.

Our articles and certain Canadian laws could delay or deter a change of control.

Our preferred shares are available for issuance from time to time at the discretion of our board of directors, without shareholder approval. Our articles allow our board, without shareholder approval, to determine the special rights to be attached to our preferred shares, and such rights may be superior to those of our Common Shares.

In addition, limitations on the ability to acquire and hold our Common Shares may be imposed by the Competition Act in Canada. This legislation permits the Commissioner of Competition of Canada to review any acquisition of a significant interest in us. This legislation grants the Commissioner jurisdiction to challenge such an acquisition before the Canadian Competition Tribunal if the Commissioner believes that it would, or would be likely to, result in a substantial lessening or prevention of competition in any market in Canada. The Investment Canada Act subjects an acquisition of control of a company by a non-Canadian to government review if the value of our assets, as calculated pursuant to the legislation, exceeds a threshold amount. A reviewable acquisition may not proceed unless the relevant minister is satisfied that the investment is likely to result in a net benefit to Canada. Any of the foregoing could prevent or delay a change of control and may deprive or limit strategic opportunities for our shareholders to sell their shares.

The exercise of all or any number of outstanding stock options, the award of any additional options, bonus shares or other stock-based awards or any issuance of shares to raise funds or acquire a business may dilute your Common Shares.

We have in the past and may in the future grant to some or all of our directors, officers and employees options to purchase our Common Shares and other stock-based awards as non-cash incentives to those persons. The issuance of any equity securities could, and the issuance of any additional shares will, cause our existing shareholders to experience dilution of their ownership interests.

Any additional issuance of shares or a decision to acquire other businesses through the sale of equity securities may dilute our investors’ interests, and investors may suffer dilution in their net book value per share depending on the price at which such securities are sold. Such issuance may cause a reduction in the proportionate ownership and voting power of all other shareholders. The dilution may result in a decline in the price of our Common Shares or a change in control.

We do not expect to pay dividends for the foreseeable future.

We have not paid any cash dividends to date and we do not intend to declare dividends for the foreseeable future, as we anticipate that we will reinvest future earnings, if any, in the development and growth of our business. Therefore, investors will not receive any funds unless they sell their Common Shares, and shareholders may be unable to sell their shares on favorable terms or at all. We cannot assure you of a positive return on investment or that you will not lose the entire amount of your investment in our Common Shares. Prospective investors seeking or needing dividend income or liquidity should not purchase our Common Shares.

The value of our securities, including our Common Shares, might be affected by matters not related to our operating performance and could subject us to securities litigation.

The value of our Common Shares may be reduced for a number of reasons, many of which are outside our control, including: 

general economic and political conditions in Canada, the United States and globally;
governmental regulation of the health care and pharmaceutical industries;
failure to achieve desired drug discovery outcomes by us or our collaborators;
failure to obtain industry partner and other third party consents and approvals, when required;
stock market volatility and market valuations;
competition for, among other things, capital, drug targets and skilled personnel;
the need to obtain required approvals from regulatory authorities;
revenue and operating results failing to meet expectations in any particular period;
investor perception of the health care and pharmaceutical industries;
limited trading volume of our Common Shares;
announcements relating to our business or the businesses of our competitors; and
our ability or inability to raise additional funds.

The concentration of the common shares ownership with insiders will likely limit the ability of the other shareholders to influence corporate matters.

As of February 29, 2016, executive officers, directors, five percent or greater shareholders, and their respective affiliated entities of the Arbutus beneficially own, in the aggregate, approximately 38% of Arbutus' outstanding common shares. As a result, these shareholders, acting together, have significant influence over most matters that require approval by Arbutus' shareholders, including the election of directors and approval of significant corporate transactions. Corporate actions might be taken even if other shareholders oppose them. This concentration of ownership might also have the effect of delaying or preventing a corporate transaction that other shareholders may view as beneficial.

If securities analysts do not publish research or reports about the business of Arbutus, or if they publish negative evaluations, the price of Arbutus' Common Shares could decline.

The trading market for the Arbutus Common Shares may be impacted by the availability or lack of research and reports that third-party industry or financial analysts publish about Arbutus. There are many large, publicly traded companies active in the biopharmaceutical industry, which may mean it will be less likely that Arbutus receives widespread analyst coverage. Furthermore, if one or more of the analysts who do cover Arbutus downgrade its stock, its stock price would likely decline. If Arbutus does not receive adequate coverage by reputable analysts that have an understanding of Arbutus' business and industry, it could fail to achieve visibility in the market, which in turn could cause its stock price to decline.

Item 1B. Unresolved Staff Comments

There are no unresolved staff comments at the moment.

Item 2. Properties
 
Our head office and principal place of business is located at 100-8900 Glenlyon Parkway, Burnaby, British Columbia, Canada, V5J 5J8. The Company leases a 51,000 square foot facility. On June 23, 2014, we signed a renewal agreement to the operating lease for its laboratory and office premises. The renewal is effective August 1, 2014 and expires July 31, 2019, but we have the option to extend the lease to 2024, 2029, and 2034. We believe that the total space available to us under our current lease will meet our needs for the foreseeable future and that additional space would be available to us on commercially reasonable terms if required.
 
Our U.S. Office is located at 3805 Old Easton Road, Doylestown, PA 18902, in an approximately 2,600 square feet of leased office space.

Item 3. Legal Proceedings

We are involved with various legal matters arising in the ordinary course of business. We make provisions for liabilities when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Such provisions are reviewed at least quarterly and adjusted to reflect the impact of any settlement negotiations, judicial and administrative rulings, advice of legal counsel, and other information and events pertaining to a particular case. Litigation is inherently unpredictable. Although the ultimate resolution of these various matters cannot be determined at this time, we do not believe that such matters, individually or in the aggregate, will have a material adverse effect on our consolidated results of operations, cash flows, or financial condition.

Alnylam Pharmaceuticals Inc.
 
On June 21, 2013, we transferred manufacturing process technology to Ascletis Pharmaceuticals (Hangzhou) Co., Ltd. (“Ascletis”) to enable them to produce ALN-VSP, a product candidate licensed to them by Alnylam Pharmaceuticals Inc., or Alnylam. We believed that under a licensing agreement with Alnylam, the technology transfer to Ascletis triggered a $5 million milestone obligation from Alnylam to Arbutus. However, Alnylam demanded a declaration that we had not yet met our milestone obligations. We disputed Alnylam’s position. To remedy this dispute, the parties commenced arbitration proceedings, as provided for under the agreement.  In addition to seeking a declaration that we had met our obligations under the agreement, we have also stated a claim for breach of contract, breach of the implied covenant of good faith and fair dealing, and fraud.  The arbitration proceeding with Alnylam has concluded resulting in no milestone payment to Arbutus.

University of British Columbia
 
Certain early work on lipid nanoparticle delivery systems and related inventions was undertaken at the University of British Columbia (UBC). These inventions are licensed to us by UBC under a license agreement, initially entered in 1998 as amended in 2001, 2006 and 2007. We have granted sublicenses under the UBC license to Alnylam as well as to Talon.  Alnylam has in turn sublicensed back to us under the licensed UBC patents for discovery, development and commercialization of RNAi products. In mid-2009, we and our subsidiary Protiva entered into a supplemental agreement with UBC, Alnylam and Acuitas Technologies, Inc., in relation to a separate research collaboration to be conducted among UBC, Alnylam and Acuitas to which we have license rights. The settlement agreement signed in late 2012 to resolve the litigation among Alnylam, Acuitas, Arbutus and Protiva provided for the effective termination of all obligations under such supplemental agreement as between and among all litigants.
 
On November 10, 2014, the University of British Columbia filed a demand for arbitration against us, BCICAC File No.: DCA-1623.  We received UBC’s Statement of Claims on January 16, 2015.  In its Statement of Claims, UBC alleges that it is entitled to $3.5 million in allegedly unpaid royalties based on publicly available information, and an unspecified amount based on non-public information.  UBC also seeks interest and costs, including legal fees. We dispute UBC’s allegation.  No dates have been scheduled for this arbitration.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Change in Functional Currency

Prior to January 1, 2016, our functional currency was the Canadian dollar. As such, all dollar amounts in this MD&A related to periods prior to and including the year-ended December 31, 2015 are presented in U.S. dollars with the functional currency as the Canadian dollar. On January 1, 2016, our functional currency changed from the Canadian dollar to the U.S. dollar based on our analysis of changes in the primary economic environment in which we operate. The change in functional currency is accounted for prospectively from January 1, 2016 and financial statements prior to and including the year-ended December 31, 2015 will not be restated for the change in functional currency. Past translation gains and losses from the application of the U.S. dollar as the reporting currency while the Canadian dollar was the functional currency are included as part of cumulative currency translation adjustment, which is reported as a component of shareholder's equity under accumulated other comprehensive loss.

OVERVIEW

Arbutus is a publicly traded industry-leading therapeutic solutions company focused on discovering, developing and commercializing a cure for patients suffering from chronic Hepatitis B Virus (HBV) infection, which leads to serious liver disease.  Our pipeline is focused on finding a cure for chronic HBV infection. This HBV pipeline consists of multiple drug candidates, with complementary mechanisms of action, which we expect to use in combination to effect patient benefit.

HBV represents a significant unmet medical need and is the cause of the most common serious liver infection in the world. The World Health Organization estimates that 350 million people worldwide are chronically infected, and other estimates suggest this could include approximately 2 million people in the United States (Kowdley et al., 2012). Individuals chronically infected with HBV are at an increased risk of developing significant liver disease, including cirrhosis, or permanent scarring of the liver, as well as liver failure and hepatocellular carcinoma (HCC) or liver cancer. According to the Hepatitis B Foundation, HBV is the cause of up to 80% of liver cancers. Individuals with liver cancer typically have a five-year survival rate of only 15%. The WHO estimates that more than 780,000 people die every year due to the consequences of hepatitis B virus disease.

Given the complex biology of HBV, we believe combination therapies are the key to HBV treatment and a potential cure, and development can be accelerated when multiple components of a combination therapy regimen are controlled by the same company.
 
HBV Focused Product Pipeline

We have a pipeline focused on finding a cure for chronic HBV infection, with the objective of developing a combination of products that intervene at different points in the viral life cycle. Given our strong scientific and research capabilities in-house, we are able to conduct preclinical combination studies to evaluate combinations of our proprietary pipeline candidates. Once compounds within the portfolio with sufficient activity have been identified, we intend, subject to discussions with regulatory authorities, to evaluate combinations of two or more drug candidates in cohorts of patients with chronic HBV infection. We expect to use these results to adaptively design additional treatment regimens for the next cohorts. We also plan to evaluate different treatment durations to determine the optimal finite duration of therapy. We plan to continue this iterative process until we select combination therapy regimens and treatment durations to conduct Phase III clinical trials intended to ultimately support regulatory filings for marketing approval.

We intend to continue to expand our HBV pipeline through internal development, acquisitions and in-licenses. We also have a research collaboration agreement with The Baruch S. Blumberg Institute that provides exclusive rights to in-license any intellectual property generated through the collaboration.

RNAi (ARB-1467 & ARB-1740)

The development of RNAi drugs allows for a completely novel approach to treating disease, which is why RNAi is considered one of the most promising and rapidly advancing frontiers in drug discovery. While there are no RNAi therapeutics approved for commercial use, there are a number of RNAi products currently in human clinical trials. RNAi products are broadly applicable as they can eliminate the production of disease-causing proteins from cells, creating opportunities for therapeutic intervention that have not been achievable with conventional drugs. Our extensive experience in antiviral drug development has been applied to our RNAi program to develop therapeutics for chronic hepatitis B infection. Small molecule nucleotide therapy has been the standard of care for chronic HBV infected patients. However, many of these patients continue to express a viral protein called HBV surface antigen (HBsAg). This protein causes inflammation in the liver leading to cirrhosis and, in some cases, HCC and death.

Our lead RNAi HBV candidate, ARB-1467 (formerly TKM-HBV), is designed to eliminate HBsAg expression in patients chronically infected with HBV. Reducing HBsAg is thought to be a key prerequisite to enable a patient’s immune system to raise an adequate immune response against the virus. The ability of ARB-1467 to inhibit numerous viral elements in addition to HBsAg increases the likelihood of affecting the viral infection. ARB-1467 is being developed as a multi-component RNAi therapeutic that simultaneously targets three sites on the HBV genome, including the HBsAg coding region. Targeting three distinct and highly conserved sites on the HBV genome is intended to facilitate potent knockdown of all viral mRNA transcripts and viral antigens across a broad range of HBV genotypes and reduce the risk of developing antiviral resistance.


42



ARB-1467 results in potent and rapid reduction in HBsAg in several preclinical models. In these models, ARB-1467 treatment resulted in reductions in both intrahepatic and serum HBsAg, as well as reductions in HBV DNA, cccDNA, Hepatitis B e antigen (HBeAg) and HBcAg (Hepatitis B c antigen). A rapid 1 log reduction in serum HBsAg was achieved with a single 1 mg/kg dose of ARB-1467 in the humanized mouse model. 1-2 log viral reductions from similar single-dose LNP treatments in two other true-infection animal models were also demonstrated. Preclinical studies conducted on infected primary human hepatocytes showed that ARB-1467 had robust and consistent activity against different viral strains representing the major clinical genotypes A, B, C and D. Our data shows that inclusion of three RNAi triggers results in a more broadly effective knockdown of hepatitis B viral elements than a single trigger alone. The mode of action of ARB-1467 complements standard of care nucleoside/nucleotide (NUC) therapy, and lack of drug antagonism has been demonstrated with entecavir, lamivudine and tenofovir on infected primary human hepatocytes, making combination therapy a viable option.

ARB-1467 was evaluated in a Phase I Single Ascending Dose trial. The Phase I clinical trial is a randomized, single-blind, placebo-controlled study, involving single ascending doses of ARB-1467 and ARB-1468. The study is assessing the safety, tolerability and pharmacokinetics of intravenous administration of the product in healthy adult subjects. In order to enable maximum dose escalation, steroid premedication was added to the Phase I protocol. No dose limiting toxicities were seen with either formulation through 0.4mg/kg, the highest dose tested in Phase I. At this time, a maximum tolerated dose has not been reached and the protocol has been amended to allow evaluation of higher doses.

The Phase II study evaluates two dose levels of ARB-1467 administered as three monthly doses in chronic HBV infected patients who are on stable background nucleot(s)ide analog therapy. Eight subjects will be enrolled in each of the two dose cohorts with six subjects receiving ARB-1467, and two receiving placebo. The ARB-1467 Phase II multi-dosing study has been initiated and single dose and multi-dose HBsAg reduction data are expected in the second half of 2016.

While we are focused on development of our lead HBV product candidates, we believe in continuous innovation and will incorporate technological and product design advancements that may result in an improvement in safety and/or efficacy. An example of this is our follow-on RNAi HBV candidate, ARB-1740. ARB-1740 is more potent than ARB-1467 in preclinical studies and has the potential to be effective at lower clinical doses than ARB-1467. ARB-1740 employs the same LNP formulation as ARB-1467 (with a different set of three RNAi triggers). We plan to file an IND (or equivalent filing) for ARB-1740 in the second half of 2016.

cccDNA Formation Inhibitors

We are developing small molecule cccDNA formation inhibitors. The inhibition of cccDNA formation is expected to reduce the amount of cccDNA in the infected liver by blocking the formation of new cccDNA. We acquired the exclusive, worldwide rights to this program through an in-license from the Blumberg Institute. We have made significant progress with the discovery of potent and small molecule cccDNA formation inhibitors. As presented at the 2015 International Meeting on Molecular Biology of Hepatitis B Viruses in October 2015, our cccDNA formation inhibitors demonstrate synergy with approved nucleot(s)ide analogs in preclinical models, which could lead to faster declines in cccDNA levels in patients than is seen with nucleot(s)ide analogs alone. We plan to file an IND (or equivalent filing) for our lead cccDNA formation inhibitor in the second half of 2016.

Core Protein/ Capsid Assembly Inhibitors

HBV core protein, or capsid, is required for viral replication and core protein may have additional roles in cccDNA function. Current nucleot(s)side analog therapy significantly reduces serum HBV DNA levels in the serum but significant HBV replication continues in the liver, thereby enabling HBV infection to persist. Effective therapy for patients requires new agents which will effectively block viral replication. We are developing core protein inhibitors (also known as capsid assembly inhibitors) as oral therapeutics for the treatment of chronic HBV infection. By inhibiting assembly of the viral capsid, the ability of hepatitis B virus to replicate is impaired, resulting in reduced cccDNA. We acquired exclusive, worldwide rights to these drug candidates through an in-license from Blumberg and Drexel University, or Drexel, and through Arbutus Inc.’s acquisition of Enantigen Therapeutics, Inc. (Enantigen). We plan to file an IND (or equivalent filing) for our lead candidate in the second half of 2016.


43



TLR9 Agonist (ARB-1598)

Immune stimulation by toll-like receptor (TLR) agonists may overcome the immunologic blocks that allow chronic HBV persistence, including direct activation of the host’s innate antiviral response. Licensed from Cytos Biotechnology Ltd., (“Cytos”), ARB-1598 (formerly CYT003) is a biological carrier which is filled with the immunostimulatory oligonucleotide called G10, a TLR-9 agonist. ARB-1598 has been shown to directly activate B cells and stimulates human plasmacytoid dendritic cells to secrete Interferon alpha, and has previously been utilized in human trials in other indications. ARB-1598 also activates other antigen presenting cells indirectly and promotes the development of TH1 type cytokine response, which is thought to be potentially beneficial in promoting anti-HBV T cell immunity. ARB-1598 is undergoing preclinical evaluation to establish its utility for HBV, and if there is a clear support for this application, we plan to initiate clinical development of ARB-1598 in chronically infected HBV patients in 2016.

Other Research Programs

Surface Antigen Secretion Inhibitors

We are developing multiple small molecule orally bioavailable inhibitors of HBV surface antigen production and secretion. By inhibiting the production and secretion of HBV surface antigen from infected cells, we expect that the immune response of patients treated with this therapy can reengage and thereby mount a more credible response to a hepatitis B virus infection.

cccDNA Epigenetic Modifiers

In addition to cccDNA formation inhibitors, we are developing cccDNA epigenetic modifiers. By controlling cccDNA transcription, we anticipate that we may be able to inhibit the formation of new virus and sub viral particles from cccDNA. This development program, which is currently in the discovery research stage, is based on proof of concept data generated by Blumberg using known inhibitors of enzymes involved in DNA information processing.

STING Agonists

We are developing stimulator of interferon genes (STING) agonists. By activating interferon genes, we anticipate that the body can produce additional interferon alpha and beta, which have antiviral properties. Our development program, which is currently in the discovery research stage, is based on proof of concept data in mice generated by Blumberg which showed that STING agonists can elicit an antiviral response and inhibit HBV replication in mouse liver cells. In collaboration with Blumberg, our plan is to identify potent, orally active small molecule human STING agonists that possess the desired characteristics to progress into human clinical studies.

Cyclophilin Inhibitor (OCB-030)

We licensed from NeuroVive Pharmaceutical AB, or (“NeuroVive”), the exclusive rights to develop and commercialize cyclophilin inhibitor drug candidates, including OCB-030, for the treatment of hepatitis B. After extensive preclinical evaluation of OCB-030 and other competitive cyclophilin inhibitors against HBV, we have concluded that cellular cyclophillins do not play a role in HBV chronic infection and further development of OCB-030 is unwarranted. As a result, we made the decision in October 2015 to discontinue the development of OCB-030 and have suspended our interest in the cyclophilin inhibitor class.

Our Proprietary Delivery Technology

Development of RNAi therapeutic products is currently limited by the instability of the RNAi trigger molecules in the bloodstream and the inability of these molecules to access target cells or tissues following administration. Delivery technology is necessary to protect these drugs in the bloodstream to allow efficient delivery and cellular uptake by the target cells. Arbutus has developed a proprietary delivery platform called Lipid Nanoparticle (LNP). The broad applicability of this platform to RNAi develoment has established Arbutus as a leader in this new area of innovative medicine.

Our proprietary LNP delivery technology allows for the successful encapsulation of RNAi trigger molecules in LNP administered intravenously, which travel through the bloodstream to target tissues or disease sites. LNPs are designed to protect the triggers, and stay in the circulation long enough to accumulate at disease sites, such as the liver or cancerous tumors. LNPs are then taken up into the target cells by a process called endocytosis. Subsequent activation by the changing environment inside the cell causes the LNP to release the trigger molecules, which can then successfully mediate RNAi.

Ongoing Advancements in LNP Technology

Our LNP technology represents the most widely adopted delivery technology in RNAi, which has enabled several clinical trials and has been administered to hundreds of human subjects. Because LNP can enable a wide variety of nucleic acid triggers, including mRNA, we continue to see new product development and partnering opportunities based on our industry-leading delivery expertise and intellectual property. We presented preclinical data in October 2013 at the International mRNA Health Conference in Tubingen, Germany, and in February 2014 at the AsiaTIDES Conference in Toyko, Japan. This data demonstrated that mRNA encapsulated and delivered using our proprietary LNP technology can be effectively delivered and expressed in the liver in tumors and other specific tissues of therapeutic interest.

Arbutus continues to explore opportunities to generate value from its LNP platform technology, which is well suited to deliver therapies based on RNAi, mRNA, gene editing, as well as other technologies.

Suspended Non-HBV RNAi Assets

Our intent is to focus our efforts on discovering, developing and commercializing a cure for patients suffering from chronic HBV infection. As such, pending completion of ongoing studies associated with TKM-PLK1, we have suspended further development of our non-HBV assets and are exploring different strategic options to maximize the value of these assets. Our non-HBV assets include our LNP-based product candidates TKM-PLK for oncology, TKM-Ebola and TKM-Marburg for hemorrhagic fever viruses, TKM-HTG for metabolic disorders, and TKM-ADLH for severe alcohol use disorder. Additional information on these programs can be found in Part I, Item 1, “— Business-Suspended Non-HBV RNAi Assets,” of this annual report on Form 10-K.

Partner Programs

Patisiran (ALN-TTR02)

Alnylam has a license to use our IP to develop and commercialize products and may only grant access to our LNP technology to its partners if it is part of a product sublicense. Alnylam’s license rights are limited to patents that we have filed, or that claim priority to a patent that was filed, before April 15, 2010. Alnylam does not have rights to our patents filed after April 15, 2010 unless they claim priority to a patent filed before that date. Alnylam will pay us low single digit royalties as Alnylam’s LNP-enabled products are commercialized.

In July 2015, Alnylam announced initiation of a Phase III open label OLE study with patisiran (APOLLO-OLE) to evaluate the long-term safety and tolerability of patisiran in ATTR amyloidosis patients with FAP who were previously enrolled in the APOLLO Phase III study. In September 2015, Alnylam reported evidence of reduced pathogenic, misfolded TTR monomers and oligomers in TTR-mediated amyloidosis patients with FAP, and in November 2015 it reported that patisiran demonstrates continued evidence for potential halting of neuropathy progression and improvement in nerve fiber density in patients with FAP. New Drug Application filing for this program is expected in 2017. The patisiran program represents the most clinically advanced application of our LNP delivery technology. Furthermore, Alnylam’s results demonstrate that multi-dosing with our LNP has been well-tolerated with treatments out to 21 months.

Marqibo®

Marqibo®, originally developed by Arbutus, is a novel, sphingomyelin/cholesterol liposome-encapsulated formulation of the FDA-approved anticancer drug vincristine. Marqibo’s approved indication is for the treatment of adult patients with Philadelphia chromosome-negative acute lymphoblastic leukemia (Ph-ALL) in second or greater relapse or whose disease has progressed following two or more lines of anti-leukemia therapy. Our licensee, Spectrum Pharmaceuticals, Inc. (Spectrum), launched Marqibo through its existing hematology sales force in the United States. We are entitled to mid-single digit royalty payments based on Marqibo’s commercial sales. Spectrum has ongoing trials evaluating Marqibo in three additional indications, which are: first line use in patients with Philadelphia Negative Acute Lymphoblastic Leukemia (Ph-ALL), Pediatric ALL and Non-Hodgkin’s lymphoma.


45



DCR-PH1

In November 2014, we signed a licensing and collaboration agreement with Dicerna Pharmaceuticals, Inc. to utilize our LNP delivery technology exclusively in Dicerna's primary hyperoxaluria type 1 (PH1) development program. Dicerna will use our third generation LNP technology for delivery of DCR-PH1, Dicerna's product incorporating its Dicer substrate RNA (DsiRNA) molecule, for the treatment of PH1, a rare, inherited liver disorder that often results in kidney failure and for which there are no approved therapies. In December 2015, Dicerna announced initiation of dosing in healthy volunteers with plans to initiate the Phase I clinical trial in patients with PH1 in 2016. 

Strategic Alliances, Licensing Agreements, and Research Collaborations

Alnylam Pharmaceuticals, Inc.

Alnylam has a license to use our IP to develop and commercialize products and may only grant access to our LNP technology to its partners if it is part of a product sublicense. Alnylam’s license rights are limited to patents that we have filed, or that claim priority to a patent that was filed, before April 15, 2010. Alnylam does not have rights to our patents filed after April 15, 2010 unless they claim priority to a patent filed before that date. Alnylam will pay low single digit royalties as Alnylam’s LNP-enabled products are commercialized. Alnylam currently has three LNP-based products in clinical development: ALN-TTR02 (patisiran), ALN-VSP, and ALN-PCS02.

Our licensing agreement with Alnylam grants us IP rights for the development and commercialization of RNAi therapeutics for specified targets. In consideration for these three exclusive and 10 non-exclusive licenses, we have agreed to pay single-digit royalties to Alnylam on product sales, with milestone obligations of up to $8.5 million on the non-exclusive licenses and no milestone obligations on the three exclusive licenses. Alnylam has also pursued two other LNP-based products through clinical development: ALN-VSP (liver cancer), and ALN-PCS02 (hypercholesterolemia). Alnylam will pay Arbutus low single digit royalties based on commercial sales of Alnylam’s LNP-enabled products.

We have entered an arbitration proceeding with Alnylam, as provided for under our licensing agreement, to resolve a matter related to a disputed $5 million milestone payment to Arbutus from Alnylam related to its ALN-VSP product. The arbitration proceeding with Alnylam has concluded resulting in no milestone payment to Arbutus.

Acuitas Therapeutics Inc.

Consistent with the terms of the settlement agreement signed in November 2012, we finalized and entered a cross-license agreement with Acuitas (formerly AlCana Technologies, Inc.) in December 2013. The terms of the cross-license agreement provide Acuitas with access to certain of our earlier IP generated prior to April 2010. At the same time, the terms provide us with certain access to Acuitas’ technology and licenses in the RNAi field, along with a percentage of each milestone and royalty payment with respect to certain products. Acuitas has agreed that it will not compete in the RNAi field for a period of five years, ending in November 2017.

Dicerna Pharmaceuticals, Inc.

In November 2014, we signed a licensing agreement and a development and supply agreement with Dicerna to license our LNP delivery technology for exclusive use in Dicerna's PH1 development program. Dicerna will use Arbutus’ third generation LNP technology for delivery of DCR-PH1, Dicerna's product incorporates its DsiRNA molecule, for the treatment of PH1, a rare, inherited liver disorder that often results in kidney failure and for which there are no approved therapies. Under the agreements, Dicerna paid Arbutus $2.5 million upfront and will potentially make payments of $22 million in aggregate development milestones, plus a mid-single-digit royalty on future PH1 sales. This partnership also includes a supply agreement under which we will provide clinical drug supply and regulatory support for the rapid advancement of this product candidate.

Monsanto Company

In January 2014, we signed an Option Agreement and a Service Agreement with Monsanto, and granted Monsanto an option to obtain a license to use our proprietary LNP delivery technology. The transaction supports the application of LNP technology and related IP for use in agriculture. The potential value of the transaction could reach $86.2 million following the successful completion of milestones. In January 2014, we received $14.5 million of the $17.5 million in near term payments. We received additional payments of $1.5 million each in June 2014 and October 2014 following the achievement of specific program objectives. In May 2015, the arrangement was amended to extend the option period by approximately five months and we received $1.8 million R&D payment for the extension period. As of December 31, 2015, we have received $19.3 million.

46



Following the completion of the Phase A extension period in October 2015, no further research activities were conducted under the arrangement, as Monsanto did not elect to proceed to Phase B of the research plan.

On March 4, 2016, Monsanto exercised its option to acquire 100% of the outstanding shares of PADCo, and will pay Arbutus an exercise fee of $1 million. As a result, PADCo is no longer an indirect wholly owned subsidiary of us. In connection with Monsanto’s exercise of its option, on March 4, 2016, we entered into an amended Option Agreement. We also entered into an amended Service Agreement on March 4, 2016 to give effect to the grant back to Protiva of new intellectual property created by Monsanto in connection with the exercise of its option. In addition, we entered into an amended License and Services Agreement to recognize Monsanto’s early exercise of option before Protiva’a completion of Phases B and C, and introduce a new Technology Transfer Completion Criteria through the amended Option Agreement. Each of the amended Option Agreement, amended License and Services Agreement and amendment to the Service Agreement have been filed as Exhibits to this annual report on Form 10-K.

Spectrum Pharmaceuticals, Inc.

In September 2013, we announced that our licensee, Spectrum, had launched Marqibo® through its existing hematology sales force in the United States. Since then commercial sales have occurred. Arbutus is entitled to mid-single digit royalty payments based on Marqibo®’s commercial sales. Marqibo®, which is a novel sphingomyelin/cholesterol liposome-encapsulated formulation of the FDA-approved anticancer drug vincristine, was originally developed by Arbutus. We out-licensed the product to Talon Therapeutics in 2006, and in July 2013, Talon was acquired by Spectrum. Marqibo®’s approved indication is for the treatment of adult patients with Philadelphia chromosome-negative acute lymphoblastic leukemia (Ph-ALL) in second or greater relapse or whose disease has progressed following two or more lines of anti-leukemia therapy. Spectrum has ongoing trials evaluating Marqibo® in three additional indications, which are: first line use in patients with Ph-ALL, Pediatric ALL and Non-Hodgkin’s lymphoma.

University of British Columbia

Certain early work on lipid nanoparticle delivery systems and related inventions was undertaken at the University ofBritish Columbia (UBC). These inventions are licensed to us by UBC under a license agreement, initially entered in 1998 as amended in 2001, 2006 and 2007. We have granted sublicenses under the UBC license to Alnylam as well as to Talon. Alnylam has in turn sublicensed back to us under the licensed UBC patents for discovery, development and commercialization of RNAi products. In mid-2009, we and our subsidiary Protiva entered into a supplemental agreement with UBC, Alnylam and Acuitas Technologies, Inc., in relation to a separate research collaboration to be conducted among UBC, Alnylam and Acuitas to which we have license rights. The settlement agreement signed in late 2012 to resolve the litigation among Alnylam, Acuitas, Arbutus and Protiva provided for the effective termination of all obligations under such supplemental agreement as between and among all litigants.On November 10, 2014, the University of British Columbia filed a demand for arbitration against Arbutus Biopharma Corp., BCICAC File No.: DCA-1623. We received UBC’s Statement of Claims on January 16, 2015. In its Statement of Claims, UBC alleges that it is entitled to $3.5 million in allegedly unpaid royalties based on publicly available information, and an unspecified amount based on non-public information. UBC also seeks interest and costs, including legal fees. We dispute UBC’s allegation. No dates have been scheduled for this arbitration.

Cytos Biotechnology Ltd

On December 30, 2014, Arbutus Inc., our wholly owned subsidiary, entered into an exclusive, worldwide, sub-licensable (subject to certain restrictions with respect to licensed viral infections other than hepatitis) license to six different series of compounds. The licensed compounds are Qbeta-derived virus-like particles that encapsulate TLR9, TLR7 or RIG-I agonists and may or may not be conjugated with antigens from the hepatitis virus or other licensed viruses. We have an option to expand this license to include additional viral infections other than influenza and Cytos will retain all rights for influenza, all non-viral infections, and all viral infections (other than hepatitis) for which we have not exercised an option.

In partial consideration for this license, we will be obligated to pay Cytos up to a total of $67 million for each of the six licensed compound series upon the achievement of specified development and regulatory milestones; for hepatitis and each additional licensed viral infection, up to a total of $110 million upon the achievement of specified sales performance milestones; and tiered royalty payments in the high-single to low-double digits, based upon the proportionate net sales of licensed products in any commercialized combination.


47



The Baruch S. Blumberg Institute and Drexel University

In February 2014, Arbutus Inc., our wholly owned subsidiary, entered into a license agreement with Blumberg and Drexel that granted an exclusive (except as to certain know-how and subject to retained non-commercial research rights), worldwide, sub-licensable license to three different compound series: cccDNA inhibitors, capsid assembly inhibitors and HCC inhibitors.


48



In partial consideration for this license, Arbutus Inc. paid a license initiation fee of $150,000 and issued warrants to Blumberg and Drexel. No warrants were outstanding as at the date Arbutus merged with Arbutus Inc. Under this license agreement, Arbutus Inc. also agreed to pay up to $3.5 million in development and regulatory milestones per licensed compound series, up to $92.5 million in sales performance milestones per licensed product, and royalties in the mid-single digits based upon the proportionate net sales of licensed products in any commercialized combination. We are obligated to pay Blumberg and Drexel a double digit percentage of all amounts received from the sub-licensees, subject to customary exclusions.In November 2014, Arbutus Inc. entered into an additional license agreement with Blumberg and Drexel pursuant to which it received an exclusive (subject to retained non-commercial research rights), worldwide, sub-licensable license under specified patents and know-how controlled by Blumberg and Drexel covering epigenetic modifiers of cccDNA and STING agonists. In consideration for these exclusive licenses, Arbutus Inc. made an upfront payment of $50,000. Under this agreement, we will be required to pay up to $1.0 million for each licensed product upon the achievement of a specified regulatory milestone and a low single digit royalty, based upon the proportionate net sales of compounds covered by this intellectual property in any commercialized combination. We are also obligated to pay Blumberg and Drexel a double digit percentage of all amounts received from its sub-licensees, subject to exclusions.

License Agreements between Enantigen and Blumberg and Drexel

In October 2014, Arbutus Inc., our wholly owned subsidiary, acquired all of the outstanding shares of Enantigen pursuant to a stock purchase agreement. Through this transaction, Arbutus Inc. acquired a HBV surface antigen secretion inhibitor program and a capsid assembly inhibitor program, each of which are now assets of Arbutus, following our merger with Arbutus Inc.

Under the stock purchase agreement, we agreed to pay up to a total of $21.0 million to Enantigen’s selling stockholders upon the achievement of specified development and regulatory milestones, for the first two products that contain either a capsid compound, or a HBV surface antigen compound that is covered by a patent acquired under this agreement; or a capsid compound from an agreed upon list of compounds. The amount paid could be up to a total of $102.5 million in sales performance milestones in connection with the sale of the first commercialized product by us for the treatment of HBV, regardless of whether such product is based upon assets acquired under this agreement; and low single digit royalty on net sales of such first commercialized HBV product, up to a maximum royalty payment of $1.0 million that, if paid, would be offset against our milestone payment obligations.

Under the stock purchase agreement, we also agreed that Enantigen would fulfill its obligations as they relate to the three patent license agreements with Blumberg and Drexel. Pursuant to each patent license agreement, Enantigen is obligated to pay Blumberg and Drexel up to approximately $500,000 in development and regulatory milestones per licensed product, royalties in the low single digits, and a percentage of revenue it receives from its sub-licensees.

Research Collaboration and Funding Agreement with Blumberg

In October 2014, Arbutus Inc., our wholly owned subsidiary, entered into a research collaboration and funding agreement with Blumberg under which we will provide $1.0 million per year of research funding for three years, renewable at our option for an additional three years, for Blumberg to conduct research projects in HBV and liver cancer pursuant to a research plan to be agreed upon by the parties. Blumberg has exclusivity obligations to Arbutus with respect to HBV research funded under the agreement. In addition, we have the right to match any third party offer to fund HBV research that falls outside the scope of the research being funded under the agreement. Blumberg has granted us the right to obtain an exclusive, royalty bearing, worldwide license to any intellectual property generated by any funded research project. If we elect to exercise our right to obtain such a license, we will have a specified period of time to negotiate and enter into a mutually agreeable license agreement with Blumberg. This license agreement will include the following pre negotiated upfront, milestone and royalty payments: an upfront payment in the amount of $100,000; up to $8.1 million upon the achievement of specified development and regulatory milestones; up to $92.5 million upon the achievement of specified commercialization milestones; and royalties at a low single to mid-single digit rates based upon the proportionate net sales of licensed products from any commercialized combination.

49



NeuroVive Pharmaceutical AB

In September 2014, Arbutus Inc., our wholly owned subsidiary, entered into a license agreement with NeuroVive that granted us an exclusive, worldwide, sub-licensable license to develop, manufacture and commercialize, for the treatment of HBV, oral dosage form sanglifehrin based cyclophilin inhibitors (including OCB-030). Arbutus Inc. became our wholly owned subsidiary by way of a Merger Agreement, which does not trigger any milestone payments. Under this license agreement we have been granted a non-exclusive, royalty free right and license and right of reference to NeuroVive’s relevant regulatory approvals and filings for the sole purpose of developing, manufacturing and commercializing licensed products for the treatment of HBV. Under this license agreement, we have (1) an option to expand our exclusive license to include treatment of viral diseases other than HBV and (2) an option, exercisable upon specified conditions, to expand our exclusive license to include development, manufacture and commercialization of non-oral variations of licensed products for treatment of viral diseases other than HBV. NeuroVive retains all rights with respect to development, manufacture and commercialization of licensed products and non-oral variations of licensed products for all indications (other than HBV) for which we have not exercised our option.

In partial consideration for this license, Arbutus Inc. paid NeuroVive a license fee of $1 million. We have conducted significant research and analysis on the NeuroVive Product, OCB-030. Based on this research and analysis, we have decided to discontinue the OCB-030 development program. Otherwise, the license agreement and ongoing relationship with NeuroVive remains in full effect at this time.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES
 
The significant accounting policies that we believe to be most critical in fully understanding and evaluating our financial results are revenue recognition, stock-based compensation, share purchase warrant valuation and financial instrument valuation.  These accounting policies require us to make certain estimates and assumptions.  We believe that the estimates and assumptions upon which we rely are reasonable, based upon information available to us at the time that these estimates and assumptions are made.  Actual results may differ from our estimates. Our critical accounting estimates affect our net income or loss calculation.
 
Revenue Recognition / Our primary sources of revenue have been derived from research and development collaborations and contracts, and licensing fees comprised of initial fees and milestone payments.  Payments received under research and development agreements and contracts, which are non-refundable, are recorded as revenue as services are performed and as the related expenditures are incurred pursuant to the agreement, provided collectability is reasonably assured. Revenue earned under research and development manufacturing collaborations where we bear some or all of the risk of a product manufacture failure is recognized when the purchaser accepts the product and there are no remaining rights of return. Revenue earned under research and development collaborations and contracts where we do not bear any risk of product manufacture failure is recognized in the period the work is performed. Revenue earned under contractual arrangements upon the achievement of substantive milestones is recognized in its entirety in the period the payment has been received. We evaluate whether milestones under research and development arrangements are substantive by considering: whether substantive uncertainty exists upon the execution of the arrangement; the event can only be achieved based in whole or in part on our performance or occurrence of a specific outcome resulting from the our performance; any future performance required and payment is reasonable relative to all deliverables; and, payment terms in the arrangement. Initial fees and non-substantive milestone payments are deferred and amortized into income over the estimated period of our involvement as we fulfill our obligations under our agreements.  

The revenue that we recognize is a critical accounting estimate because of the volume and nature of the revenues we receive.  Some of the research, development and licensing agreements that we have entered into contain multiple revenue elements that are to be recognized for accounting in accordance with our revenue recognition policy.  We need to make estimates as to what period the services will be delivered with respect to up-front licensing fees and milestone payments received because these payments are deferred and amortized into income over the estimated period of our ongoing involvement.  The actual period of our ongoing involvement may differ from the estimated period determined at the time the payment is initially received and recorded as deferred revenue.  This may result in a different amount of revenue that should have been recorded in the period and a longer or shorter period of revenue amortization. When an estimated period changes we amortize the remaining deferred revenue over the estimated remaining time to completion.  The rate at which we recognize revenue from payments received for services to be provided under research and development agreements depends on our estimate of work completed to date and total work to be provided. The actual total services provided to earn such payments may differ from our estimates.
 
Our DoD contract for TKM-Ebola is based on cost reimbursement plus an incentive fee. At the beginning of our fiscal year we estimate our labor and overhead rates for the year ahead. During the year, we re-estimate our labor and overhead rates and adjust our revenue accordingly. Our actual labor and overhead rates will differ from our estimate based on actual costs incurred and the proportion of our efforts on contracts and internal products versus indirect activities. Within minimum and maximum collars, the amount of incentive fee we can earn under the DoD contract varies based on our costs incurred versus budgeted costs, with the exception of the Ebola-Guinea Amendment, which has a fixed incentive fee. During the contractual period, incentive fee revenue and total costs are impacted by management’s estimate and judgments which are continuously reviewed and adjusted, as necessary, using the cumulative catch-up method.  For the years ended December 31, 2013, 2014 and 2015, we believe we were able to reliably estimate the final contract costs so have recognized the portion of expected incentive fee which has been earned to date.
 
Our revenue for 2015 was $24.9 million (2014 - $15.0 million, 2013 - $15.5 million) and deferred revenue at December 31, 2015 was $1.1 million (December 31, 2014 - $15.7 million).

Stock-based compensation / The stock-based compensation that we record is a critical accounting estimate due to the value of compensation recorded, the volume of our stock option activity, and the many assumptions that are required to be made to calculate the compensation expense.

Compensation expense is recorded for stock options issued to employees and directors using the fair value method.  We must calculate the fair value of stock options issued and amortize the fair value to stock compensation expense over the vesting period, and adjust the expense for stock option forfeitures and cancellations.  We use the Black-Scholes model to calculate the fair value of stock options issued which requires that certain assumptions, including the expected life of the option and expected volatility of the stock, be estimated at the time that the options are issued.  This accounting estimate is reasonably likely to change from period to period as further stock options are issued and adjustments are made for stock option forfeitures and cancellations. We make an estimate for stock option forfeitures at the time of grant and revise this estimate in subsequent periods if actual forfeitures differ. The term "forfeitures" is distinct from "cancellations" or "expirations" and represents only the unvested portion of the surrendered stock option. For the purpose of calculating fair value, the expected life of stock options granted is five years for employees and eight years for directors and executives. We amortize the fair value of stock options using the straight-line method over the vesting period of the options, generally a period of three years for employees and immediate vesting for directors.
 
We recorded stock-based compensation expense in 2015 of $22.1 million (2014 - $3.3 million, 2013 - $0.9 million) which includes compensation expense related to the expiration of repurchase rights on replacement awards issued as consideration in the acquisition of Arbutus Inc. of $16.7 million - refer to business combination section below.
 
Share purchase warrant valuation / The valuation of share purchase warrants is a critical accounting estimate due to the value of liabilities recorded and the many assumptions that are required to calculate the liability, resulting in the classification of our warrant liability as a level 3 financial instrument.
 
We classify warrants in our consolidated balance sheet as liabilities and revalue them at each balance sheet date. Any change in valuation is recorded in our statement of operations. We use the Black-Scholes pricing model to value the warrants. Determining the appropriate fair-value model and calculating the fair value of registered warrants requires considerable judgment. A small change in the estimates used may cause a relatively large change in the estimated valuation. Due to ongoing changes in our business and general stock market conditions, we continuously assess our warrant fair value assumptions. We adjust the estimated expected life as appropriate, based on the pattern of exercises of our warrants. During the year-ended December 31, 2015, warrant exercise activity continued to decline; as a result, we increased the remaining expected life of outstanding warrants to nine months and seventeen months effective July 1, 2015. As at December 31, 2015, the remaining expected life is three months and eleven months for outstanding warrants expiring in June 2016 and February 2017, respectively.

Our expected volatility is calculated based on our historic share price fluctuations over the same period as our estimated expected life of our outstanding warrants. The risk-free interest rate is based on the Government of Canada rate for bonds with a maturity similar to the expected remaining life of the warrants at the valuation date.
  
We recorded a gain for the change in fair value of warrant liability in 2015 of $3.3 million (2013 – loss of $10.4 million, 2013 – loss of $3.5 million).


50



Financial instruments valuation / The valuation of our financial instruments, include Monsanto’s option to acquire either the shares or assets of Protiva Agricultural Development Company Inc. and contingent consideration related to estimated potential future milestone payments to the former Enantigen shareholders as described in the business combination section below. These are critical accounting estimate due to the potential value of the liability and the many assumptions we must make to calculate the fair values of these liabilities.

We classify the financial instrument in our consolidated balance sheet as a liability and revalue it at each balance sheet date. Any change in the valuation is recorded in our statement of operations. We used a discounted cash flow model to value the financial instrument. Determining the appropriate fair value model and calculating the fair value of the financial instrument requires considerable judgment, including probability of success and risk-adjusted discount rates. Changes in assumptions used may cause a relatively large change in the estimated valuation. The initial valuation of the financial instrument was determined to be nil for Monsanto's option and no change in the fair value of the financial instrument was recorded as at December 31, 2015. The initial valuation of the contingent consideration was determined to be $6,727,000, and we have determined that the fair value increased to $7,497,000 as at December 31, 2015. We recorded an adjustment for the increase in fair value of $770,000 in our statement of operations and comprehensive loss. The increase in fair value is a result of our research and development progress bringing the contingent payments forward in terms of timing.

Business combination / The purchase price allocation is a critical accounting estimate due to the many assumptions that are required to calculate the fair value of assets acquired and liabilities assumed during a business combination.
 
We account for our business combinations using the acquisition method. Under this method, the fair value of the consideration transferred is allocated to the fair values of assets acquired and liabilities assumed. In determining the fair value of the consideration transferred, the acquisition date market price of common shares issued was used. The total consideration transferred is comprised of common shares issued without subjects and common shares issued replacement awards, which are subject to repurchase provisions. As at the acquisition date, we determined the total fair value of the replacement awards and attributed a portion of the replacement awards to pre-combination service as part of the total acquisition consideration, and a portion to post-combination service, which is recognized as compensation expense over the expiry period of repurchase provision rights subsequent to the acquisition date. The fair value of the repurchase awards was determined using the Black-Scholes pricing model with assumed risk-free interest rate of 0.74%, volatility of 81%, a zero dividend yield and an expected life of 4 years. In July 2015, the expiration period of the repurchase rights was amended, resulting in a prospective adjustment to recognize the remaining compensation expense on a straight-line basis over the revised expiration period.

In addition, we make estimates to determine the fair values of assets acquired and liabilities assumed, which include judgments in our determinations of acquired intangible assets and assessment of the fair value of existing property and equipment. Assumed liabilities can include other contingency reserves existing at the time of acquisition. Contingent consideration is recorded for cash payments due upon the completion of certain future development and performance milestones. This liability is recorded as at the acquisition date as the fair value of the contingent consideration, estimated using the income method which utilizes various inputs such as probability of success and risk-adjusted discount rates. In addition, contingent consideration is recorded at its fair value at subsequent reporting dates, with any change in fair value from the previous reporting date recorded in the statement of operations and comprehensive loss, as discussed above.

Goodwill is recognized on acquisition as the excess of the purchase price over the estimated fair values of net identifiable assets acquired and liabilities assumed. Acquisition related expenses are separately recognized from the business combination and are expensed as incurred.

When establishing fair values, we make significant estimates and assumptions, especially with respect to intangible assets. Intangible assets acquired and recorded by us may include patents, intellectual property, and in-process research and development. Estimates include, but are not limited to the forecasting of future cash flows and discount rates.

Our estimates for the fair values of assets acquired and liabilities assumed with respect to our acquisition of Arbutus Inc. are final for the period ended December 31, 2015. We have engaged a third-party valuation specialist to assist us to determine the fair values. Our estimates of fair values are based upon assumptions that we believe to be reasonable, but which are inherently uncertain and unpredictable; therefore, actual results may differ from estimates, thereby impacting our earnings.

Goodwill and intangible assets - Impairment / Intangible assets classified as indefinite-lived and goodwill are not amortized, but are evaluated for impairment annually using a measurement date of December 31. In addition, if there is a major event indicating that the carrying value of an asset may not be recoverable, then management will perform an impairment test by comparing the discounted cash flow values to each asset’s carrying value to determine if a write down is necessary. Such indicators include, but are not limited to on an ongoing basis: (a) industry and market considerations such as an increased competitive environment or an adverse change in legal factors including an adverse assessment by regulators; (b) an accumulation of costs significantly in excess of the amount originally expected for the development of the asset; (c) current period operating or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with the use of the asset; and (d) if applicable, a sustained decrease in share price.

In assessing impairment, significant judgments are required by management to estimate future cash flows, appropriate discount rates, and other estimates and assumptions that could materially affect the determination of fair value. These judgments include the use of, but are not limited to: projected results of operations and forecast cash flows based on our corporate model as approved by our Board of Directors, third party forecasts and data and other macroeconomic indicators that forecasts market conditions and our estimated future revenues and growth.

In October 2015, we announced the discontinuance of the cyclophilin drug candidate, OCB-030. Although the final conclusion on discontinuance was made subsequent to the end of the third quarter, it reflected our best estimate as at September 30, 2015, and as such we recorded an estimated impairment charge of $38.0 million in Q3 2015. We revised certain estimates in Q4, and finalized our purchase price allocation which resulted in an incremental adjustment of $1.0 million to the fair value of cyclophilins. The total impairment charge of $39.0 million is reflected in our statement of operations and cumulative loss for the year-ended December 31, 2015.

Goodwill is subject to a two-step impairment test. The first step compares the fair value of the reporting unit to the carrying amount, which includes goodwill. If the carrying amount exceeds the implied fair value of the goodwill, the second step measures the amount of the impairment loss. As part of the impairment evaluation of goodwill, we identified only one reporting unit to which the total carrying amount of goodwill has been assigned. We used a valuation specialist to assist us in determining the fair value of the reporting unit under the income approach. For step one of the impairment test, we determined that the fair value of the reporting unit exceeded the carrying value of the reporting unit, and as such, step two was not required. . In addition to the income approach, we considered the market capitalization of approximately $242.8 million as at December 31, 2015. Although the Company’s carrying value of $547.7 million exceeded the market capitalization, we reconciled the income approach determination of fair value with the market capitalization by considering macroeconomic factors, and as such, we do not believe that market capitalization appropriately reflected the value of the Company for the purpose of testing goodwill impairment. No impairment charge on goodwill was recorded for the year ended December 31, 2015.

Quarterly Trends
 
Revenue / Our revenue is derived from research and development collaborations and contracts, licensing fees, milestone and royalty payments. Over the past two years, our principal sources of ongoing revenue have been our Monsanto collaboration and our contract with the DoD to advance TKM-Ebola. The DoD contract was terminated in October 2015 and we are currently working through close out procedures with the DoD. Our collaboration with Monsanto effectively ended in October when Phase A research was completed. We expect revenue to continue to fluctuate due to the irregular nature of licensing and milestone receipts under our collaboration and licensing contracts.
 

53



In Q3 2010 we signed a contract with the DoD to develop TKM-Ebola and have since incurred significant program costs related to equipment, materials and preclinical and clinical studies. These costs are included in our research, development, collaborations and contracts expenses. These costs are fully reimbursed by the DoD, and this reimbursement amount is recorded as revenue. DoD revenue from the TKM-Ebola program also compensates us for labor and overheads and provides an incentive fee. As described in our critical accounting policies in our Annual Report, we estimate the labor and overhead rates to be charged under our TKM-Ebola contract and update these rate estimates throughout the year. In April 2014, we signed a contract modification to increase the stage one targeted funding by $2.1 million to $43.8 million. The additional funding is to compensate us for unrecovered costs related to the temporary stop-work period that occurred in 2012 and to provide additional overhead funding should it be required. In Q1 2014, we earned $3.2 million in DoD revenue, due partially to an increase in activity as we moved into a Phase I Clinical Trial. In Q2 2014, we earned $0.9 million in DoD revenue due to lower contract activity as our clinical trial data was with the FDA for review. DoD revenue increased in Q3 2014 with an increase in activity as we prepared a response to the FDA’s partial clinical hold on our Phase I Clinical Trial. In October 2014, the DoD exercised a contract option adding $7.0 million to the contract for the scale-up and manufacture of TKM-Ebola-Guinea, our product targeting the Ebola-Makona (formerly known as Ebola-Guinea) strain responsible for the outbreak in West Africa. DoD revenue increased in Q4 2014 and Q1 2015 as we purchased materials and manufactured TKM-Ebola-Guinea. In Q2 2015, material purchases and subcontract work related to TKM-Ebola-Guinea were less significant. In July 2015, we announced that activities had been suspended and in October 2015, we received formal notification from the DoD to terminate the TKM-Ebola-Guinea manufacturing and IND submission activities, subject to completion of our post-termination obligations. In Q4, we purchased some lipids back from the DoD and proceeded with contract close out.

In January 2014, we signed an Option Agreement and a Services Agreement with Monsanto for the use of our proprietary delivery technology and related intellectual property in agriculture. Over the option period, which is expected to be approximately four years, Monsanto will make payments to us to maintain their option rights. In Q1 2014, we received $14.5 million of the $17.5 million near term payments, of which $4.5 million relates to research services and $10.0 million for the use of our technology. In June 2014 and October 2014, we received further payments of $1.5 million each, following the completion of specified program developments. In 2015, we received an additional $1.8 million related to research services. The payments are being recognized as revenue on a straight-line basis over the option period. In Q4 2015, we did not receive further payments from Monsanto for the continuance of research activities under the arrangement. As such, we revised our estimated option period end date to December 31, 2015, resulting in the full release of Monsanto deferred revenue and recognition of $11.8 million in Monsanto revenue in Q4 2015. In March 2016, Monsanto exercised its option to acquire 100% of the outstanding shares of Protiva Agricultural Development Company Inc. (PADCo), for which Monsanto will pay us an exercise fee of $1.0 million in Q1 2016.

In November 2014, we signed a License Agreement and a Development and Supply Agreement with Dicerna for the use of our proprietary delivery technology and related technology intended to develop, manufacture, and commercialize products related to treatment of PH1. In Q4 2014, we received an upfront payment of $2.5 million, which is being recognized over the period over which we provide services to Dicerna, estimated to complete in Q1 2017. We have recognized Dicerna collaboration revenue for inventory manufacture and provision of development services.

Under our licensing and collaboration arrangements with Alnylam and Acuitas, we earn licensing fee revenue from Acuitas as well as further potential development and commercial milestones from Alnylam for the use of our LNP technology.
 
In 2013, we began to earn royalties from Spectrum with respect to the commercial sales of Marqibo.

Included in “other collaborations and contract revenue” is revenue from a BMS batch formulation agreement. In August 2014, the collaboration expired and both parties’ obligations under the agreement ended. Revenue recognized in Q3 2014 relates to the release of the deferred revenue balance of $1.6 million.

Expenses / Expenses consist primarily of clinical and pre-clinical trial expenses, personnel expenses, consulting and third party expenses, reimbursable collaboration expenses, consumables and materials, patent filing expenses, facilities, stock-based compensation and general corporate costs. Impairment of intangible assets is also included i operating expenses.
 

54



Our expenses have increased in the past eight quarters due to an increase in our research and development activities as we seek to move more products into the clinic. In Q1 2014, we dosed the first subject in human clinical trials of TKM-Ebola. In Q2 2014, we initiated a Phase I/II Clinical Trial for TKM-PLK1 in patients with HCC. In Q4 2014, we filed a Canadian Clinical Trial Application (CTA) for TKM-HBV and received clearance to conduct a Phase I Clinical Trial, as well as initiated manufacturing of TKM-Ebola-Guinea for emergency use in West Africa. We also incurred research and development expenses related to identifying new targets. In Q1 2015, we initiated a Phase I Clinical Trial for TKM-HBV and incurred significant material costs related to the TKM-Ebola-Guinea contract with the DoD. In addition, we incurred $9.3 million in costs for professional fees related to completing the merger with Arbutus Inc. (formerly OnCore). In Q2 2015, we incurred an incremental $2.9 million in R&D expenses related to our HBV programs acquired through the merger with Arbutus Inc. In Q3 2015, we incurred $5.5 million in incremental R&D expenses primarily related to an increase in HBV and HCC clinical trial expenses due to an increase in patient enrollment and a ramp up in spending on Arbutus Inc. HBV programs. Also in Q3 2015, we recorded an estimated impairment charge of $38.0 million as we discontinued our cyclophilin inhibitor program based on our conclusion that cyclophilins do not play a meaningful role in HBV biology. In Q4, 2015, we continued to incur R&D expense related to our HBV programs.
 
Other income (losses) / Other income (losses) consist primarily of changes in the fair value of our warrant liability and foreign exchange differences. Other losses increased in Q1 2014 and Q3 2014 due primarily to the increase in fair value of our warrant liability. Increases in our share price from the previous reporting date result in an increase in the fair value of our warrant liability, and vice versa. We expect to see future changes in the fair value of our warrant liability and these changes will largely depend on the change in the Company’s share price, any change in our assumed rate of share price volatility, our assumptions for the expected lives of the warrants and warrant exercises.

In Q3 and Q4 2015, we recorded $11.8 million and $5.5 million respectively in foreign exchange gains largely on our cash and investments due to the appreciation of the U.S. dollar against the Canadian dollar from the previous period.

Income tax benefit / Income tax benefit relates to the decrease in deferred tax liability associated with the impairment charge recorded on acquired intangible assets. In Q3 2015, we recorded $15.2 million of income tax benefit for the estimated impairment of our cyclophilin inhibitor program, OCB-030. In Q4, we recorded a further $1.0 million in income tax benefit due to the revision of fair value of cyclophilins.
 
Net loss / Fluctuations in our net loss are explained by changes in revenue, expenses, other income (losses) and income tax as discussed above.
 
Fourth quarter of 2015 / Our Q4 2015 net loss was $5.2 million ($0.10 basic and diluted loss per common share) as compared to a net loss of $6.2 million ($0.27 basic and diluted loss per common share) for Q4 2014.
 
Revenue was $12.7 million in Q4 2015 as compared to $4.4 million in Q4 2014. The increase was largely due to the recognition of $11.8 million in Monsanto revenue due to our revised estimate of the option period.
 
Research, development, collaborations and contracts expenses increased to $14.9 million in Q4 2015 as compared to $11.9 million in Q4 2014. In Q4 2015, we incurred incremental expenses related to our HBV programs acquired from Arbutus Inc. . In addition, we recorded $6.0 million in non-cash compensation expense related to the expiry of repurchase rights on shares issued as part of the consideration paid for the merger with Arbutus Inc. (refer to notes to the financial statements), of which $1.5 million has been included as part of research, development, collaborations and contracts expense, and $4.5 million included as part of general and administrative expense.

Other gains in Q4 2015 primarily consists of a $0.5 million decrease in the fair value of our warrant liability, and a foreign exchange gain of $5.5 million on our US dollar funds. In Q4 2015, we recorded a $0.8 million charge related to the increase in the fair value of contingent consideration - see financial statement notes for further details.

Revenue contracts are covered in more detail in the overview section of this discussion.

DoD revenue

In July 2015, we announced that Ebola related activities were being suspended and, in Q4 2015, we received formal notification from the DoD terminating the contract, subject to the completion of certain post-termination obligations. We do not expect to record significant revenue from the DoD contract after December 31, 2015.


56



Monsanto revenue

In January 2014, we received $14.5 million, of which $4.5 million relates to research services and $10.0 million for the use of our technology. In June and October 2014, we received payments of $1.5 million each, following the completion of specified program developments. In May and September 2015, we received $1.05 million and $0.75 million for research services. We are recognizing this revenue on a straight-line basis over the option period. As we did not receive further payments from Monsanto for the continuance of research activities under the arrangement, we revised our estimated option period end date as December 31, 2015, resulting in the full release of Monsanto deferred revenue of $11.8 million, resulting in the recognition of $15.0 million in Monsanto revenue for the year ended December 31, 2015.

Dicerna revenue
 
In November 2014, we signed a License Agreement and a Development and Supply Agreement with Dicerna for the use of our proprietary delivery technology and related technology intended to develop, manufacture, and commercialize products related to the treatment of PH1. Licensing fee revenue recognized for the year-ended December 31, 2015 relates to the earned portion of the upfront payment of $2.5 million for the use our of technology, which is being recognized over the period over which we provide services to Dicerna, estimated to complete in March 2017. Collaboration revenue for the year-ended December 31, 2015 relates to inventory manufactured for and services provided to Dicerna.

Alnylam and Acuitas revenue
 
Under our licensing and collaboration arrangements with Alnylam and Acuitas, we earn licensing fee revenue from Acuitas as well as further potential development and commercial milestones from Alnylam for the use of our LNP technology.
 
BMS revenue
 
In May 2010 we signed a formulation agreement with BMS under which BMS paid us $3.0 million to make a certain number of LNP formulations over the following four year period. The contract expired in 2014 with no further obligation for either party. Revenue recognized in 2014 relates to the manufactured batches shipped to BMS during the year and the subsequent release of the deferred revenue balance upon the expiration of the contract.
 
Spectrum revenue
 
In September 2013, Spectrum announced that they had shipped the first commercial orders of Marqibo. We continue to earn royalties on the sales of Marqibo, which uses a license to our technology.

Research, development, collaborations and contracts
 
Research, development, collaborations and contracts expenses consist primarily of clinical and pre-clinical trial expenses, personnel expenses, consulting and third party expenses, consumables and materials, as well as a portion of stock-based compensation and general corporate costs.
 
R&D expenses increased during 2015 as compared to 2014 as we increased our spending on TKM-HBV for which Phase 1 clinical trials were initiated in 2015. We also incurred incremental costs related to an increase in activities for the preclinical HBV programs we acquired from our merger with Arbutus Inc. In addition, we increased research activities related to our collaboration contracts with the DoD, Monsanto, and Dicerna.


57



R&D compensation expense increased in 2015 as compared to 2014 due to an increase in the number of employees in support of our expanded portfolio of product candidates, as well as from our merger with Arbutus Inc. In addition, in the year ended December 31, 2015, we incurred a total of $16.7 million of incremental non-cash compensation expense related to the expiry of repurchase rights on shares issued as part of the consideration paid for the merger with Arbutus Inc. (refer to notes to the financial statements), of which $4.2 million has been included as part of research, development, collaborations and contracts expense, and $12.5 million included as part of general and administrative expense.
 
A significant portion of our research, development, collaborations and contracts expenses are not tracked by project as they benefit multiple projects or our technology platform and because our most-advanced programs are not yet in late-stage clinical development. However, our collaboration agreements contain cost-sharing arrangements pursuant to which certain costs incurred under the project are reimbursed. Costs reimbursed under collaborations typically include certain direct external costs and hourly or full-time equivalent labor rates for the actual time worked on the project. In addition, we have been reimbursed under government contracts for certain allowable costs including direct internal and external costs. As a result, although a significant portion of our research, development, collaborations and contracts expenses are not tracked on a project-by-project basis, we do, however, track direct external costs attributable to, and the actual time our employees worked on, our collaborations and government contracts.
 
General and administrative
 
General and administrative expenses increased in 2015 compared to 2014 due largely to an increase in compensation expense linked to our increase in employee base and incremental corporate expenses to support the growth of the Company following the completion of our merger with Arbutus Inc. This includes an incremental non-cash compensation expense we incurred related to the expiry of repurchase rights on shares issued as part of consideration paid for the merger with Arbutus Inc. (see above). Expenses were also higher in 2015 due to legal costs incurred in relation to the May 2015 arbitration hearing against Alnylam.
 
Acquisition costs
 
In 2015, we incurred $9.7 million in costs for professional fees related to completing the merger with Arbutus Inc. - see overview. This is a one-time cost specific to the merger with Arbutus Inc., and such costs are only incurred when a business combination occurs.

Impairment of intangible assets

For the year-ended December 31, 2015, we recorded a total impairment charge of $39.0 million based on our decision to discontinue our development of cyclophilin inhibitors. The decision was based on extensive preclinical evaluations of OCB-030, and other competitive cyclophilin inhibitors, following the acquisition of Arbutus Inc., which concluded that cyclophilins do not play a meaningful role in HBV biology.

Foreign exchange gains
 
For the year-ended December 31, 2015, we recorded a foreign exchange gain of $21.8 million, which is primarily an unrealized gain related to an appreciation in the value of our U.S. dollar funds from the previous period when converted to our functional currency of Canadian dollars. Cumulative translation adjustments, which result from converting from our functional currency of Canadian dollars to our reporting currency of U.S. dollars, do not impact our net loss calculation and are not included in foreign exchange gains (losses), but are included in cumulative translation adjustment in other comprehensive loss.


58



Increase in fair value of warrant liability
 
In conjunction with equity and debt financing transactions in 2011 and 2012, we issued warrants to purchase our common share. We are accounting for the warrants under the authoritative guidance on accounting for derivative financial instruments indexed to, and potentially settled in, a company’s own stock, on the understanding that in compliance with applicable securities laws, the registered warrants require the issuance of registered securities upon exercise and do not sufficiently preclude an implied right to net cash settlement. At each balance sheet date the warrants are revalued using the Black-Scholes model and the change in value is recorded in the consolidated statement of operations and comprehensive income (loss).

Generally, a decrease in our share price from the previous reporting date results in a decrease in the fair value of our warrant liability and vice versa.
 
We expect to see future changes in the fair value of our warrant liability and these changes will largely depend on the change in the Company’s share price, and, to a lesser extent, any change in our assumed rate of share price volatility, our assumptions for the expected lives of the warrants and warrant exercises.

Increase in fair value of contingent consideration
 
The contingent consideration represents the estimated regulatory, development and sales milestone payments payable to the previous Enantigen shareholders. Enantigen was acquired by Arbutus Inc. in 2014. As at the acquisition date of Arbutus Inc., the contingent consideration had an estimated fair value of approximately $6,727,000. Contingent consideration is a financial liability, and we determine its fair value at each reporting period with any changes in fair value from the previous reporting period recorded in the statement of operations and comprehensive loss. For the period ended December 31, 2015, we performed an evaluation of the fair value of the contingent consideration using the probability weighted assessment of likelihood of milestone payments as described above and determined the fair value of the contingent consideration has increased by $770,000 to $7,497,000. The increase in fair value has been recorded in other losses in the statement of operations and comprehensive loss for the year-ended December 31, 2015.

Income tax benefit

For the year-ended December 31, 2015, we recorded an income tax benefit of $16.2 million due to the decrease in deferred tax liability resulting from the impairment charge we recorded for the discontinuance of our cyclophilin inhibitor program.
 
Year ended December 31, 2014 compared to the year ended December 31, 2013
 
For the fiscal year ended December 31, 2014, our net loss was $38.8 million ($1.80 basic and diluted loss per common share) as compared to a net loss of $14.1 million ($0.92 basic and diluted loss per common share) for 2013.

DoD revenue
 
In April 2014, we signed a contract modification with the DoD to increase the stage one targeted funding by a further $2.1 million to $43.8 million. The additional funding is to compensate us for unrecovered costs incurred related to the temporary stop-work period that occurred in 2012 and to provide additional overhead funding should it be required. In October 2014, the DoD exercised an option valued at $7.0 million, awarded to us to manufacture TKM-Ebola-Guinea targeting the Ebola-Guinea strain responsible for the outbreak in West Africa.
Under the contract, we are being reimbursed for costs incurred, including an allocation of overheads, and we are being paid an incentive fee.

DoD revenues and related contract expenses were lower in 2014 as compared to 2013 as we were nearing the end of stage one of the contract and most activities for this stage had been completed. The reduction in stage one revenue in 2014 was offset by the addition of the $7.0 million award for the manufacture of TKM-Ebola-Guinea towards the end of 2014.
 
Monsanto revenue

On January 13, 2014, we signed an Option Agreement and a Services Agreement (together, the “Agreements”) with Monsanto. Under the Agreements, Monsanto has an option to acquire a license to use our proprietary delivery technology and related intellectual property for use in agriculture. Over the option period, which is expected to be approximately four years, we will provide lipid formulations for Monsanto’s research and development activities, and Monsanto will make certain payments to us to maintain their option rights (see Overview for further discussion).

In January 2014, we received $14.5 million, of which $4.5 million relates to research services and $10.0 million for the use of our technology. In June and September 2014, we received payments of $1.5 million each, following the completion of specified program developments. We are recognizing this revenue on a straight-line basis over the option period. For the year-ended December 31, 2014, we recorded an aggregate of $3.8 million in revenue for the use of our technology and for research activities.

Alnylam and Acuitas revenue
 
On November 12, 2012, we entered into a new licensing agreement with Alnylam that replaces all earlier licensing, cross-licensing, collaboration, and manufacturing agreements. We also entered into a separate cross license agreement with Acuitas, which includes milestones and royalty payments, and Acuitas has agreed not to compete in the RNAi field for five years.
 
In November 2013, Alnylam initiated a Phase III trial with ALN-TTR02, also known as patisiran, and an associated $5.0 million development milestone was paid to us in December 2013. In March 2014, we earned a $0.15 million milestone payment from Acuitas following their receipt of a milestone from Alnylam with the initiation of the ALN-TTR02 Phase III trial.

On June 21, 2013, we transferred manufacturing process technology to Ascletis to enable them to produce ALN-VSP, a product candidate licensed to them by Alnylam. We believe that under our licensing agreement with Alnylam, the technology transfer to Ascletis triggers a $5.0 million milestone obligation from Alnylam to us. However, Alnylam has demanded a declaration that we have not yet met its milestone obligations. We dispute Alnylam’s position. To remedy this dispute, we have commenced arbitration proceedings with Alnylam, as provided for under the agreement.  The hearing for this arbitration occurred in May, 2015. We have not recorded any revenue in respect of this milestone.
 
BMS revenue
 
In May 2010 we signed a formulation agreement with BMS under which BMS paid us $3.0 million to make a certain number of LNP formulations over the following four year period. Revenue recognized in 2012 and 2013 relates to LNP batches the company produced in proportion to the maximum LNP formulations that may be required under the contract. As at December 31, 2013, we intended to offer BMS an extension to the agreement’s end date from May 10, 2014 to December 31, 2014. Extending the agreement would have given BMS more time to order LNP batches. The offer extension resulted in a cumulative revenue adjustment recorded for the year-ended December 31, 2013. In August 2014, we received notification from BMS that the extension would not occur. Revenue recognized for the year-ended December 31, 2014 relates to the batches shipped to BMS during the period and the release of any remaining deferred revenue balance now that the agreement has expired and no further obligation with either party.


60



Dicerna revenue
 
In November 2014, we signed a License Agreement and a Development and Supply Agreement with Dicerna for the use of our proprietary delivery technology and related technology intended to develop, manufacture, and commercialize products related to treatment of PH1. Revenue recognized for the year-ended December 31, 2014 relates to the earned portion of the upfront payment of $2.5 million for the use our of technology, which is being recognized over the period over which we provide services to Dicerna, estimated to complete in March 2017.
 
Spectrum revenue
 
In September 2013, Spectrum announced that they had shipped the first commercial orders of Marqibo. For the year-ended December 31, 2014, we earned royalties of $0.2 million on the sales of Marqibo, which uses a license to our technology.

Research, development, collaborations and contracts
 
Research, development, collaborations and contracts expenses consist primarily of clinical and pre-clinical trial expenses, personnel expenses, consulting and third party expenses, consumables and materials, as well as a portion of stock-based compensation and general corporate costs. 

In 2013, research and development costs were primarily related to our internal earlier-stage research programs, moving TKM-PLK1 into Phase I/II clinical trial, and new targets identification: TKKM-HBV and TKM-ALDH2. In 2014, our research and development costs increased as we incurred incremental costs related to the progress of moving additional products into the clinic: the initiation of Phase I /II clinical trials in patients with HCC resulting in the expansion in the number of clinical trials sites and patients accrual for TKM-PLK1, significant research and preclinical spending on TKM-HBV to file a CTA to move into the clinic, as well as an increase in manufacturing activities under the DoD contract in response to the Ebola outbreak in West Africa. In addition, we incurred incremental research and development spending for new partner collaborations we entered into in 2014, as well as spending on new targets identification - see Overview for further details.
 
Compensation expenses increased in 2014 as compared to 2013. There was an increase in workforce of 38 employees in 2014 to support our expanded portfolio of product candidates. In addition, R&D stock-based compensation expense increased significantly due, in part, to the increase in our share price.

In 2014, we also incurred $0.5 million in acquisition costs related to the acquisition of Arbutus Inc. (formerly OnCore) that completed in March 2015 - see overview.
 
A significant portion of our research, development, collaborations and contracts expenses are not tracked by project as they benefit multiple projects or our technology platform and because our most-advanced programs are not yet in late-stage clinical development. However, our collaboration agreements contain cost-sharing arrangements pursuant to which certain costs incurred under the project are reimbursed. Costs reimbursed under collaborations typically include certain direct external costs and hourly or full-time equivalent labor rates for the actual time worked on the project. In addition, we have been reimbursed under government contracts for certain allowable costs including direct internal and external costs. As a result, although a significant portion of our research, development, collaborations and contracts expenses are not tracked on a project-by-project basis, we do, however, track direct external costs attributable to, and the actual time our employees worked on, our collaborations and government contracts.


61



General and administrative
 
General and administrative expenses increased in 2014 due largely to an increase in compensation expenses. Our employee base grew in support of our expanding pipeline and we had a significant increase in stock-based compensation expense due, in part, to the increase in our share price. We incurred incremental spending on legal fees and consultants related to new compliance requirements linked to the growth of the Company.

Increase in fair value of warrant liability

In conjunction with equity and debt financing transactions in 2011 and 2012, we issued warrants to purchase our common share. We are accounting for the warrants under the authoritative guidance on accounting for derivative financial instruments indexed to, and potentially settled in, a company’s own stock, on the understanding that in compliance with applicable securities laws, the registered warrants require the issuance of registered securities upon exercise and do not sufficiently preclude an implied right to net cash settlement. At each balance sheet date the warrants are revalued using the Black-Scholes model and the change in value is recorded in the consolidated statement of operations and comprehensive income (loss).
 
The aggregate increase in value of our common share purchase warrants outstanding at December 31, 2014 was $10.4 million as compared to an increase in the value of common share purchase warrants outstanding at the end of 2013 of $3.5 million. The increases are a result of increases in the Company’s share price from the previous reporting dates.

Since our incorporation, we have financed our operations through the sales of shares, units, debt, revenues from research and development collaborations and licenses with corporate partners, interest income on funds available for investment, and government contracts, grants and tax credits.
 
At December 31, 2015, we had cash and cash equivalents of $166.8 million and short and long-term investments of $24.6 million, totaling $191.4 million as compared to cash, cash equivalents, and short-term investments of $112.2 million at December 31, 2014.
 

62



Operating activities used $54.8 million in cash in 2015 as compared to $12.4 million used in 2014 and $6.7 million used in 2013. The increase in cash used from operating activities was primarily related to the expansion of our research and development as a result of both organic growth and our acquisition of Arbutus Inc. in March 2015. Non-cash items to reconcile net loss used by operating activities include impairment of intangible assets of $39.0 million, with an offsetting income tax benefit of $16.2 million.
 
Investing activities provided cash of $7.7 million compared to $43.0 million of cash used in 2014 and $0.7 million used in 2013. Cash provided in 2015 was due to settlement of guaranteed investment certificates during the year.
 
On October 22, 2013, we completed an underwritten public offering of 3,750,000 common shares, at a price of $8.00 per share, representing gross proceeds of $30.0 million. On November 1, 2013, the offering’s underwriter completed the exercise of its over-allotment option to purchase a further 562,500 shares at $8.00 bringing the aggregate financing gross proceeds to $34.5 million. The cost of the financing, including commissions and professional fees, was $2.5 million, resulting in net proceeds of $32.0 million.
 
On March 18, 2014, we completed an underwritten public offering of 2,125,000 common shares, at a price of $28.50 per share, representing gross proceeds of $60.5 million. We are using these proceeds to develop and advance product candidates through clinical trials, as well as for working capital and general corporate purposes.

On March 25, 2015, we completed an underwritten public offering of 7,500,000 common shares, at a price of $20.25 per share, representing gross proceeds of $151.9 million. The cost of financing, including commissions and professional fees, was approximately $9.7 million, which gave us net proceeds of $142.2 million. We plan to use these proceeds to develop and advance product candidates through clinical trials, as well as for working capital and general corporate purposes.
 
Cash requirements / At December 31, 2015 we held $166.8 million in cash and cash equivalents and $24.6 million in short- and long-term investments. On March 25, 2015, we raised net proceeds of $142.2 million from a public offering. We believe we have sufficient cash resources for at least the next 12 months. In the future, substantial additional funds will be required to continue with the active development of our pipeline products and technologies. In particular, our funding needs may vary depending on a number of factors including:

the need for additional capital to fund future business development programs;
revenues earned form our current collaborative partnership and licensing agreement with Dicerna;
revenues earned from our legacy collaborative partnerships and licensing agreements, including milestone payments from Alnylam and royalties from sales of Marqibo from Spectrum;
the extent to which we continue the development of our product candidates, add new product candidates to our pipeline, or form collaborative relationships to advance our products;
our decisions to in-license or acquire additional products or technology for development, in particular for our HBV programs;
our ability to attract and retain corporate partners, and their effectiveness in carrying out the development and ultimate commercialization of our product candidates;
whether batches of drugs that we manufacture fail to meet specifications resulting in delays and investigational and remanufacturing costs;
the decisions, and the timing of decisions, made by health regulatory agencies regarding our technology and products;
competing technological and market developments; and
costs associated with prosecuting and enforcing our patent claims and other intellectual property rights, including litigation and arbitration arising in the course of our business activities.

We will seek to obtain funding to maintain and advance our business from a variety of sources including public or private equity or debt financing, collaborative arrangements with pharmaceutical companies and government grants and contracts. There can be no assurance that funding will be available at all or on acceptable terms to permit further development of our products especially in light of the current difficult climate for investment in early stage biotechnology companies.
 
If adequate funding is not available, we may be required to delay, reduce or eliminate one or more of our research or development programs or reduce expenses associated with non-core activities. We may need to obtain funds through arrangements with collaborators or others that may require us to relinquish most or all of our rights to product candidates at an earlier stage of development or on less favorable terms than we would otherwise seek if we were better funded. Insufficient financing may also mean failing to prosecute our patents or relinquishing rights to some of our technologies that we would otherwise develop or commercialize.

Material commitments for capital expenditures / As at the date of this discussion we do not have any material commitments for capital expenditures.

OFF-BALANCE SHEET ARRANGEMENTS

We do not have any off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that is material to investors.

CONTRACTUAL OBLIGATIONS
 
Facility lease / On June 23, 2014, we signed an agreement to renew the lease for our Burnaby office and lab facility. The lease term is for five years, commencing August 1, 2014 with three additional renewal terms of five years each. On March 24, 2015, our U.S. office signed a one year lease agreement for office and lab facilities. On October 1, 2015, we signed an amendment and extended the lease to December 31, 2016. We have the option to renew for another term of one year.
 
Product development partnership with the Canadian Government / We entered into a Technology Partnerships Canada (TPC) agreement with the Canadian Federal Government on November 12, 1999.  Under this agreement, TPC agreed to fund 27% of our costs incurred prior to March 31, 2004, in the development of certain oligonucleotide product candidates up to a maximum contribution from TPC of $7.2 million (C$9.3 million).  As at December 31, 2015, a cumulative contribution of $2.7 million (C$3.7 million) had been received and we do not expect any further funding under this agreement.  In return for the funding provided by TPC, we agreed to pay royalties on the share of future licensing and product revenue, if any that is received by us on certain non-siRNA oligonucleotide product candidates covered by the funding under the agreement.  These royalties are payable until a certain cumulative payment amount is achieved or until a pre-specified date.  In addition, until a cumulative amount equal to the funding actually received under the agreement has been paid to TPC, we agreed to pay a 2.5% royalty on any royalties we receive for Marqibo.
 
In September 2013, we began to earn royalties on Marqibo and the cumulative amount paid or accrued up to December 31, 2015 was $0.01 million resulting in the contingent amount due to TPC being $2.7 million (C$3.7 million).
 
License agreement with Marina Biotech, Inc. (“Marina”) / On November 29, 2012, we announced a worldwide, non-exclusive license to a novel RNAi payload technology called Unlocked Nucleobase Analog (“UNA”) from Marina for the development of RNAi therapeutics.
 
UNA technology can be used in the development of RNAi therapeutics, which treat disease by silencing specific disease causing genes. UNAs can be incorporated into RNAi drugs and have the potential to improve them by increasing their stability and reducing off-target effects.
 
Under the license agreement we will make milestone payments of up to $3.3 million, plus royalties, on each product that we develop that uses Marina’s UNA technology. The upfront fee and license payment were expensed to research, development, collaborations and contracts expense.
 
Effective August 9, 2013, Marina’s UNA technology was acquired by Arcturus Therapeutics, Inc. (“Arcturus”) and the UNA license agreement between us and Marina was assigned to Arcturus. The terms of the license are otherwise unchanged.

Contingent consideration from OnCore acquisition of Enantigen and License Agreements between Enantigen and Blumberg and Drexel
 
In October 2014, OnCore acquired all of the outstanding shares of Enantigen pursuant to a stock purchase agreement. Through this transaction, OnCore acquired a HBV surface antigen secretion inhibitor program and a capsid assembly inhibitor program, each of which are now assets of Arbutus, following the Company’s merger with Arbutus Inc. - see notes to the financial statements.
 
Under the stock purchase agreement, OnCore agreed to pay up to a total of $21.0 million to Enantigen’s selling stockholders upon the achievement of certain triggering events related to Enantigen’s two programs in pre-clinical development related to HBV therapies. The first triggering event is the enrollment of first patient in Phase 1b clinical trial in HBV patients, which we do not expect to occur in the next twelve-month period.


64



The regulatory, development and sales milestone payments have an estimated fair value of approximately $6.7 million as at the date of acquisition of Arbutus Inc., and have been treated as contingent consideration payable in the purchase price allocation.
Contingent consideration is considered as a financial liability, and measured at its fair value at each reporting period with any changes in fair value from the previous reporting period recorded in the statement of operations and comprehensive loss. For the period ended December 31, 2015, we performed an evaluation of the fair value of the contingent consideration using the probability weighted assessment of likelihood of milestone payments as described above. We determined the fair value of the contingent consideration has increased by $0.8 million to $7.5 million and the increase in fair value has been recorded in other losses in the statement of operations and comprehensive loss for the year-ended December 31, 2015.

Drexel and Blumberg

In February 2014, OnCore entered into a license agreement with Blumberg and Drexel that granted an exclusive, worldwide, sub-licensable license to three different compound series: cccDNA inhibitors, capsid assembly inhibitors and HCC inhibitors.
 
In partial consideration for this license, OnCore paid a license initiation fee of $0.2 million and issued warrants to Blumberg and Drexel. Under this license agreement, OnCore also agreed to pay up to $3.5 million in development and regulatory milestones per licensed compound series, up to $92.5 million in sales performance milestones per licensed product, and royalties in the mid-single digits based upon the proportionate net sales of licensed products in any commercialized combination. We are obligated to pay Blumberg and Drexel a double digit percentage of all amounts received from the sub-licensees, subject to customary exclusions.
 
In November 2014, OnCore entered into an additional license agreement with Blumberg and Drexel pursuant to which it received an exclusive, worldwide, sub-licensable license under specified patents and know-how controlled by Blumberg and Drexel covering epigenetic modifiers of cccDNA and STING agonists. In consideration for these exclusive licenses, OnCore made an upfront payment of $0.1 million. Under this agreement, we will be required to pay up to $1.0 million for each licensed product upon the achievement of a specified regulatory milestone and a low single digit royalty, based upon the proportionate net sales of compounds covered by this intellectual property in any commercialized combination. We are also obligated to pay Blumberg and Drexel a double digit percentage of all amounts received from its sub-licensees, subject to exclusions.
 
Research Collaboration and Funding Agreement with Blumberg

In October 2014, OnCore entered into a research collaboration and funding agreement with Blumberg under which we will provide $1.0 million per year of research funding for three years, renewable at our option for an additional three years, for Blumberg to conduct research projects in HBV and liver cancer pursuant to a research plan to be agreed upon by the parties. Blumberg has exclusivity obligations to Arbutus with respect to HBV research funded under the agreement. In addition, Arbutus has the right to match any third party offer to fund HBV research that falls outside the scope of the research being funded under the agreement. Blumberg has granted Arbutus the right to obtain an exclusive, royalty bearing, worldwide license to any intellectual property generated by any funded research project. If we elect to exercise its right to obtain such a license, we will have a specified period of time to negotiate and enter into a mutually agreeable license agreement with Blumberg. This license agreement will include the following pre negotiated upfront, milestone and royalty payments: an upfront payment in the amount of $0.1 million; up to $8.1 million upon the achievement of specified development and regulatory milestones; up to $92.5 million upon the achievement of specified commercialization milestones; and royalties at a low single to mid-single digit rates based upon the proportionate net sales of licensed products from any commercialized combination.
 
NeuroVive Pharmaceutical AB (“NeuroVive”)
 
In September 2014, OnCore entered into a license agreement with NeuroVive that granted them an exclusive, worldwide, sub-licensable license to develop, manufacture and commercialize, for the treatment of HBV, oral dosage form sanglifehrin based cyclophilin inhibitors (including OCB-030). Under this license agreement, Arbutus has been granted a non-exclusive, royalty free right and license and right of reference to NeuroVive’s relevant regulatory approvals and filings for the sole purpose of developing, manufacturing and commercializing licensed products for the treatment of HBV. Under this license agreement, Arbutus has (1) an option to expand its exclusive license to include treatment of viral diseases other than HBV and (2) an option, exercisable upon specified conditions, to expand its exclusive license to include development, manufacture and commercialization of non-oral variations of licensed products for treatment of viral diseases other than HBV. NeuroVive retains all rights with respect to development, manufacture and commercialization of licensed products and non-oral variations of licensed products for all indications (other than HBV) for which we have not exercised our option.
 

65



In partial consideration for this license, OnCore paid NeuroVive a license fee of $1.0 million. As described in the notes to our financial statements, Arbutus Inc. became our wholly owned subsidiary by way of a Merger Agreement, which does not trigger any milestone payments. We have conducted significant research and analysis on the NeuroVive Product, OCB-030. Based on this research and analysis, we have decided to discontinue the OCB-030 development program.  Otherwise, the license agreement and ongoing relationship with NeuroVive remains in full effect.

Cytos Biotechnology Ltd (“Cytos”)
 
On December 30, 2014, OnCore entered into an exclusive, worldwide, sub-licensable (subject to certain restrictions with respect to licensed viral infections other than hepatitis) license to 6 different series of compounds. The licensed compounds are Qbeta-derived virus-like particles that encapsulate TLR9, TLR7 or RIG-I agonists and may or may not be conjugated with antigens from the hepatitis virus or other licensed viruses.  Arbutus has an option to expand this license to include additional viral infections other than influenza and Cytos will retain all rights for influenza, all non-viral infections, and all viral infections (other than hepatitis) for which it has not exercised its option. 
 
In partial consideration for this license, we are obligated to pay Cytos up to a total of $67.0 million for each of the 6 licensed compound series upon the achievement of specified development and regulatory milestones; for hepatitis and each additional licensed viral infection, up to a total of $110.0 million upon the achievement of specified sales performance milestones; and tiered royalty payments in the high-single to low-double digits, based upon the proportionate net sales of licensed products in any commercialized combination.

To the extent we are unable to reasonably predict the likelihood, timing or amount of such payments; we have excluded them from the table above. Our technology in-licenses are further described in the Overview section of this discussion.
 
We also have contracts and collaborative arrangements that require us to undertake certain research and development work as further explained elsewhere in this discussion. It is not practicable to estimate the amount of these obligations.

IMPACT OF INFLATION

Inflation has not had a material impact on our operations.

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (FASB) or other standard setting bodies that we adopt as of the specified effective date. Unless otherwise discussed, we believe that the impact of recently issued standards that are not yet effective will not have a material impact on our financial position or results of operations upon adoption.
 
In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842).: Recognition and Measurement of Financial Assets and Financial Liabilities. The update supersedes Topic 840, Leases and requires the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous GAAP. Topic 842 retains a distinction between finance leases and operating leases, with cash payments from operating leases classified within operating activities in the statement of cash flows. The amendments in this update are effective for fiscal years beginning after December 15, 2018 for public business entities, which for the Company means January 1, 2019. We do not plan to early adopt this update. The extent of the impact of this adoption has not yet been determined.

In September 2015, the FASB issued ASU 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments. The update eliminates the requirement to retrospectively adjust the provisional amounts recognized at the acquisition date with a corresponding adjustment to goodwill during the measurement period when new information is obtained about the facts and circumstances that existed as of the acquisition date, that if known, would have affected the measurement of the amounts initially recognized or would have resulted in the recognition of additional assets or liabilities. The amendments in this update are effective for fiscal years beginning after December 15, 2015, which for the Company means January 1, 2016, and should be applied prospectively to adjustments to provisional amounts that occur after the effective date of this update. Early application is permitted for financial statements that have not been issued. We have adopted this update and applied it to the acquisition of Arbutus Inc.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (ASC 606). The standard is intended to clarify the principles for recognizing revenue and to develop a common revenue standard for U.S. GAAP and IFRS by creating a new Topic 606, Revenue from Contracts with Customers. This guidance supersedes the revenue recognition requirements in ASC 605, Revenue Recognition, and supersedes some cost guidance included in Subtopic 605-35, Revenue Recognition - Construction-Type and Production-Type Contracts. The core principle of the accounting standard is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those good or services. The amendments should be applied by either (1) retrospectively to each prior reporting period presented; or (2) retrospectively with the cumulative effect of initially applying this ASU recognized at the date of initial application. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date to defer the effective date of Update 2014-09 for all entities by one year. The new guidance would be effective for fiscal years beginning after December 15, 2017, which for us means January 1, 2018. Entities are permitted to adopt in accordance with the original effective date if they choose. We have not yet determined the extent of the impact of adoption.
 
In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. The update is intended to provide guidance in GAAP about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. Under amendments to GAAP, the assessment period is within one year after the date that the financial statements are issued (or available to be issued). The amendments are effective for the annual period ending after December 15, 2016, which for us means January 1, 2017, and for annual periods and interim periods thereafter. Early application is permitted. We do not plan to early adopt this update. The extent of the impact of this adoption has not yet been determined.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

Interest rate risk

We are exposed to market risk related to changes in interest rates, which could adversely affect the value of our interest rate sensitive assets and liabilities.  We do not hold any instruments for trading purposes and investment decisions are governed by a Board approved Investment Policy. As at December 31, 2015, we had cash and cash equivalents of $166.8 million and short- and long-term investments of $24.6 million, as compared to $72.2 million of cash and cash equivalents and $40.0 million of short-term investments as at December 31, 2014. We invest our cash reserves in high interest saving accounts and guaranteed investment certificates and term deposits with varying terms to maturity (not exceeding two years) issued by major Canadian banks, selected with regard to the expected timing of expenditures for continuing operations and prevailing interest rates. The fair value of our cash investments as at December 31, 2015 equal to the face value of those investments and the value reported in our balance sheet.  Due to the relatively short-term nature of the investments that we hold, we do not believe that the results of operations or cash flows would be affected to any significant degree by a sudden change in market interest rates relative to our investment portfolio.  Our debt instrument sensitive to changes in interest rate is our warrant liability with its fair value determined using the Black-Scholes model, which uses interest rate as an input. We have estimated the effects on our warrant liability based on a one percentage point hypothetical adverse change in interest rates as of December 31, 2015 and 2014. We determined the hypothetical fair value using the same Black-Scholes model, and determined that an increase in the interest rates of one percentage point would have had an adverse change to our warrant liability of $0.01 million and $0.01 million as of December 31, 2015 and 2014, respectively.

Foreign currency exchange risk
 
In addition, we are exposed to market risk related to changes in foreign currency exchange rates. We have not entered into any agreements or purchased any instruments to hedge possible currency risks at this time.  We manage our US dollar exchange rate risk by, whenever possible, using cash received from US dollar revenues and financing to pay US dollar expenses. Given our increasing level of US dollar expenses, our policy is to maintain US and Canadian dollar cash and investment balances based on long term forecasts of currency needs thereby creating a natural currency hedge. As of December 31, 2015 and 2014, an adverse change of one percentage point in the foreign currency exchange rates of Canadian to US dollars would have resulted in an incremental loss of $2.1 million and $0.7 million, respectively. We recorded foreign exchange gains of $21.8 million and $4.1 million for the fiscal years ended December 31, 2015 and 2014, respectively.

On January 1, 2016, our functional currency changed from the Canadian dollar to the U.S. dollar based on our analysis of changes in the primary economic environment in which we operate. We will continue to incur substantial expenses and hold cash and investment balances in Canadian dollars, and as such, will remain subject to risks associated with foreign currency fluctuations.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Directors of Arbutus Biopharma Corporation
 
We have audited the accompanying consolidated balance sheets of Arbutus Biopharma Corporation as of December 31, 2015 and December 31, 2014 and the related consolidated statements of operations and comprehensive loss, stockholders’ equity and cash flows each of the years in the three-year period ended December 31, 2015. These consolidated financial statements are the responsibility of Arbutus Biopharma Corporation’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.
 
We conducted our audits in accordance with Canadian generally accepted auditing standards and the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.
 
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Arbutus Biopharma Corporation as of December 31, 2015 and December 31, 2014, and its consolidated results of operations and its consolidated cash flows each of the years in the three-year period ended December 31, 2015 in conformity with US generally accepted accounting principles.
 
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Arbutus Biopharma Corporation’s internal control over financial reporting as of December 31, 2015, based on the criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated March 9, 2016 expressed an unqualified opinion on the effectiveness of Arbutus Biopharma Corporation’s internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
 
To the Shareholders and Board of Directors of Arbutus Biopharma Corporation
 
We have audited Arbutus Biopharma Corporation’s internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Arbutus Biopharma Corporation’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.
 
We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
 
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
 
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
 
In our opinion, Arbutus Biopharma Corporation maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) .
 
We also have audited, in accordance with Canadian generally accepted auditing standards and the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Arbutus Biopharma Corporation as of December 31, 2015 and 2014, and the related consolidated statements of operations and comprehensive loss, stockholders’ equity and cash flows for each of the years in the three-year period ended December 31, 2015, and our report dated March 9, 2016 expressed an unqualified opinion on those consolidated financial statements.

ARBUTUS BIOPHARMA CORPORATION
(formerly Tekmira Pharmaceuticals Corporation)
 
Notes to Consolidated Financial Statements
(Tabular amounts in thousands of US Dollars, except share and per share amounts) 

1. Nature of business and future operations

Arbutus Biopharma Corporation (the “Company” or “Arbutus”) is a Canadian biopharmaceutical business dedicated to discovering, developing, and commercializing a cure for patients suffering from chronic hepatitis B infection (HBV), a disease of the liver caused by the hepatitis B virus (“HBV”). The Company is also developing a pipeline focused on advancing novel RNA interference therapeutics (RNAi) leveraging the Company’s expertise in Lipid Nanoparticle (LNP) technology.

Effective July 31, 2015, the corporate name changed from Tekmira Pharmaceuticals Corporation (Tekmira) to Arbutus Biopharma Corporation. Also effective July 31, 2015, the corporate name of the wholly-owned subsidiary, OnCore Biopharma, Inc. (OnCore) changed to Arbutus Biopharma, Inc. (Arbutus Inc.). Including Arbutus Inc., the Company has four wholly-owned subsidiaries: Protiva Biotherapeutics Inc. (Protiva), Protiva Biotherapeutics (USA) Inc. (Protiva USA), and Protiva Agricultural Development Company Inc. (“PADCo”). In March 2016, Monsanto exercised its option to acquire 100% of the outstanding shares in PADCo - refer to note 13 subsequent events.

The success of the Company is dependent on obtaining the necessary regulatory approvals to bring its products to market and achieve profitable operations. The continuation of the research and development activities and the commercialization of its products are dependent on the Company’s ability to successfully complete these activities and to obtain adequate financing through a combination of financing activities and operations. It is not possible to predict either the outcome of future research and development programs or the Company’s ability to continue to fund these programs in the future.

2. Significant accounting policies 

Basis of presentation

Arbutus Biopharma Corporation (formerly Tekmira Pharmaceuticals Corporation) was incorporated on October 6, 2005 as an inactive wholly owned subsidiary of Inex Pharmaceuticals Corporation (Inex). Pursuant to a “Plan of Arrangement” effective April 30, 2007, the business and substantially all of the assets and liabilities of Inex were transferred to the Company. The consolidated financial statements for all periods presented herein include the consolidated operations of Inex until April 30, 2007 and the operations of the Company thereafter. 

The Company has four wholly-owned subsidiaries as at December 31, 2015: Arbutus Biopharma, Inc. (formerly OnCore Biopharma, Inc.) Protiva Biotherapeutics Inc. (Protiva), Protiva Biotherapeutics (USA) Inc. (Protiva USA), and Protiva Agricultural Development Company Inc. (“PADCo”). Protiva and Protiva USA were acquired on May 30, 2008. PADCo was incorporated on January 9, 2014. Arbutus Inc. was acquired by way of a Merger Agreement on March 4, 2015, which included Arbutus Inc.'s wholly-owned subsidiary, Enantigen Therapeutics, Inc. (Enantigen) - see note 3. Enantigen was merged with Arbutus Inc. on September 30, 2015.

These consolidated financial statements include the accounts of the Company and three of its wholly-owned subsidiaries, Arbutus Inc., Protiva and Protiva USA. All intercompany transactions and balances have been eliminated on consolidation.

The Company records its investment in PADCo using the equity method. The Company has determined that PADCo is a variable interest entity (“VIE”) of which it is not the primary beneficiary. The Company is not the primary beneficiary as it does not have the power to make decisions that most significantly affect the economic performance of the VIE nor does the Company have the right to receive benefits or the obligation to absorb losses that in either case could potentially be significant to the VIE. PADCo is described further in note 4(b). In March 2016, Monsanto exercised its option to acquire PADCo - refer to note 13 subsequent events.

Use of estimates

The preparation of the consolidated financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions about future events that affect the reported amounts of assets, liabilities, revenue, expenses, contingent assets and contingent liabilities as at the end or during the reporting period. Actual results could significantly differ from those estimates. Significant areas requiring the use of management estimates relate to purchase price allocation, valuation of intangible assets and goodwill, recognition of revenue, stock-based compensation, valuation of warrant liability and financial instrument, and the amounts recorded as accrued liabilities, contingent consideration, and income tax recovery.

Cash and cash equivalents

Cash and cash equivalents are all highly liquid instruments with an original maturity of three months or less when purchased. Cash equivalents are recorded at cost plus accrued interest. The carrying value of these cash equivalents approximates their fair value.

Short-term and long-term investments

The Company acquired guaranteed investment certificates and a term deposit during the year, which are classified as short-term and long-term investments on the balance sheet respectively. Short-term investments have original maturities exceeding three months, and have remaining maturities less than one year. Long-term investments have remaining maturities exceeding twelve months. Short-term and long-term investments accrue interest daily based on a fixed interest rate for the term. The carrying value of these investments are recorded at cost plus accrued interest, which approximates their fair value. All investments are governed by the Board approved Investment Policy for the Company.

Fair value of financial instruments

We measure certain financial instruments and other items at fair value.

To determine the fair value, we use the fair value hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use to value an asset or liability and are developed based on market data obtained from independent sources. Unobservable inputs are inputs based on assumptions about the factors market participants would use to value an asset or liability. The three levels of inputs that may be used to measure fair value are as follows:
 
Level 1 inputs are quoted market prices for identical instruments available in active markets.
Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability either directly or indirectly. If the asset or liability has a contractual term, the input must be observable for substantially the full term. An example includes quoted market prices for similar assets or liabilities in active markets.
Level 3 inputs are unobservable inputs for the asset or liability and will reflect management’s assumptions about market assumptions that would be used to price the asset or liability.

Assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurements. Changes in the observability of valuation inputs may result in a reclassification of levels for certain securities within the fair value hierarchy.

The Company’s financial instruments consist of cash and cash equivalents, short-term and long-term investments, accounts receivable, accounts payable and accrued liabilities, warrants and financial instruments. Long-term investments approximate fair value due to the interest rates being at prevailing market rates.

The carrying values of cash and cash equivalents, short-term investments, accounts receivable and accounts payable and accrued liabilities approximate their fair values due to the immediate or short-term maturity of these financial instruments.

As quoted prices for the warrants are not readily available, the Company has used a Black-Scholes pricing model, as described in note 6, to estimate fair value. These are level 3 inputs as defined above.



76





The Company used a discounted cash flow model to determine the fair value of the financial instrument related to Monsanto’s call option to acquire the equity or all of the assets of PADCo, as described in note 4. The fair value was determined at the date of recognition, and at each reporting date. The initial fair value of the financial instrument was nil, and there has been no change to its fair value as at December 31, 2015. The assumptions used in the discounted cash flow model are level 3 inputs as defined above.

To determine the fair value of the contingent consideration, the Company uses a probability weighted assessment of the likelihood the milestones would be met and the estimated timing of such payments, and then the potential contingent payments were discounted to their present value using a probability adjusted discount rate that reflects the early stage nature of the development program, time to complete the program development, and overall biotech indices, as in note 9. The fair value was determine at the date of recognition to be $6,727,000. The Company determined the fair value of the contingent consideration has increased by $770,000 to $7,497,000 and the increase in fair value has been recorded in other losses in the statement of operations and comprehensive loss for the year-ended December 31, 2015. The assumptions used in the discounted cash flow model are level 3 inputs as defined above. 

The following tables present information about the Company’s assets and liabilities that are measured at fair value on a recurring basis, and indicates the fair value hierarchy of the valuation techniques used to determine such fair value:

 (1) As at acquisition date of March 4, 2015 - see note 3 below.

Inventory

Inventory includes materials assigned for the manufacture of products for collaborative partners and manufacturing costs for products awaiting acceptance by collaborative partners. Inventory is carried at the lower of cost and net realizable value and measured using first-in-first-out method. The cost of inventories includes all costs of purchase, costs of manufacturing and other costs incurred in bringing the inventories to their present location and condition.

Materials purchased for the Company’s own research and development products are not recorded as inventory but are expensed as incurred.
 
Property and equipment

Property and equipment is recorded at cost less impairment losses, accumulated depreciation, related government grants and investment tax credits. The Company records depreciation using the straight-line method over the estimated useful lives of the capital assets as follows:
 
Useful life (years)
Laboratory equipment
 
 
5
 
 
Computer and office equipment
2
 
 
5
Furniture and fixtures
 
 
5
 
 
 
Leasehold improvements are depreciated over their estimated useful lives but in no case longer than the lease term, except where lease renewal is reasonably assured.

If there is a major event indicating that the carrying value of property and equipment may be impaired then management will perform an impairment test and if the carrying value exceeds the recoverable value, based on undiscounted future cash flows, then such assets are written down to their fair values.

Goodwill and intangible assets

The costs incurred in establishing and maintaining patents for intellectual property developed internally are expensed in the period incurred.

78




Intangible assets consist of in-process research and development arising from the Company’s acquisition of Arbutus Inc. - see note 3. In-process research and development (IPR&D) intangible assets are classified as indefinite-lived and are not amortized. IPR&D becomes definite-lived upon the completion or abandonment of the associated research and development efforts. Intangible assets with finite useful lives are amortized on a straight-line basis over their estimated useful lives, which are the respective patent terms. Amortization begins when intangible assets with finite lives are put into use. If there is a major event indicating that the carrying value of intangible assets may be impaired, then management will perform an impairment test and if the carrying value exceeds the recoverable value, based on discounted future cash flows, then such assets are written down to their fair values.

Goodwill represents the excess of purchase price over the value assigned to the net tangible and identifiable intangible assets of Arbutus Inc. - see note 3. Goodwill has an indefinite accounting life and is therefore not amortized. Instead, goodwill is subject to a two-step impairment test on an annual basis, unless the Company identifies impairment indicators that would require earlier testing. The first step compares the fair value of the reporting unit to its carrying amount, which includes the goodwill. When the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not to be impaired, and the second step of the impairment test is unnecessary. If the carrying amount exceeds the implied fair value of the reporting unit, the second step measures the amount of the impairment loss. If the carrying amount exceeds the fair value of the reporting unit, an impairment loss is recognized equal to that excess.

The Company reviews the recoverable amount of intangible assets on an annual basis, and the annual evaluation for goodwill is performed as of December 31 each year. In addition, the Company evaluates for events or changes in the business that could indicate impairment and earlier testing. Such indicators include, but are not limited to, on an ongoing basis: (a) industry and market considerations such as increased competitive environment or adverse change in legal factors including an adverse assessment by regulators; (b) an accumulation of costs significantly in excess of the amount originally expected for the development of the asset; (c) current period operating or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with the use of the asset; and (d) if applicable, a sustained decrease in share price.

Revenue recognition

The Company earns revenue from research and development collaboration and contract services, licensing fees, milestone and royalty payments. Revenues associated with multiple element arrangements are attributed to the various elements based on their relative fair values or are recognized as a single unit of accounting when relative fair values are not determinable. Non-refundable payments received under collaborative research and development agreements are recorded as revenue as services are performed and related expenditures are incurred. Non-refundable upfront license fees from collaborative licensing and development arrangements are recognized as the Company fulfills its obligations related to the various elements within the agreements, in accordance with the contractual arrangements with third parties and the term over which the underlying benefit is being conferred. The Company evaluates new arrangements for any substantive milestones by considering: whether substantive uncertainty exists upon execution of the arrangement; if the event can only be achieved based in whole or in part on the Company’s performance, or occurrence of a specific outcome resulting from the Company’s performance; any future performance required, and payment is reasonable relative to all deliverables; and, the payment terms in the arrangement. Payments received upon the achievement of substantive milestones are recognized as revenue in their entirety. Payments received upon the occurrence of milestones that are non-substantive are deferred and recognized as revenue over the estimated period of performance applicable to the associated collaborative agreement.

Revenue earned under research and development manufacturing collaborations where the Company bears some or all of the risk of a product manufacturing failure is recognized when the purchaser accepts the product and there are no remaining rights of return.

Revenue earned under research and development collaborations where the Company does not bear any risk of product manufacturing failure is recognized in the period the work is performed. For contracts where the manufacturing amount is specified, revenue is recognized as product is manufactured in proportion to the total amount specified under the contract.

Revenue and expenses under the contract with the United States Government Department of Defense (“DoD”) are being recorded using the percentage-of-completion method. Contract progress is based on costs incurred to date. Expenses under the contract are recorded in the Company’s consolidated statement of operations and comprehensive income (loss) as they are incurred. Government contract revenues related to expenses incurred under the contract are recorded in the same period as those expenses. Expenses accrued under the contract but not yet invoiced are recorded in the Company’s balance sheet as

79



accrued liabilities and accrued revenues. Equipment purchased under the contract is recorded on the Company’s balance sheet as deferred expense and deferred revenue and amortized, on a straight-line basis, over the life of the contract.

Cash or other compensation received in advance of meeting the revenue recognition criteria is recorded on the balance sheet as deferred revenue. Revenue meeting recognition criteria but not yet received or receivable is recorded on the balance sheet as accrued revenue.

Leases and lease inducements

Leases entered into are classified as either capital or operating leases. Leases which substantially transfer all benefits and risks of ownership of property to the Company are accounted for as capital leases. At the time a capital lease is entered into, an asset is recorded together with its related long-term obligation to reflect the purchase and financing.

All other leases are accounted for as operating leases wherein rental payments are expensed as incurred.

Lease inducements represent leasehold improvement allowances and reduced or free rent periods and are amortized on a straight-line basis over the term of the lease and are recorded as a reduction of rent expense.
  
Research and development costs

Research and development costs, including acquired in-process research and development expenses for which there is no alternative future use, are charged as an expense in the period in which they are incurred.

Income or loss per share

Income or loss per share is calculated based on the weighted average number of common shares outstanding. Diluted loss per share does not differ from basic loss per share for the years ended December 31, 2015, 2014 and 2013, since the effect of the Company’s stock options and warrants is anti-dilutive.
 
The following table sets out the computation of basic and diluted net income (loss) per common share:

For the year ended December 31, 2015, potential common shares of 2,899,331 were excluded from the calculation of income per common share because their inclusion would be anti-dilutive (December 31, 20142,221,233; December 31, 20133,064,767).
 
Government grants and refundable investment tax credits

Government grants and tax credits provided for current expenses is included in the determination of income or loss for the year, as a reduction of the expenses to which it relates. Government grants and tax credits towards the acquisition of property and equipment is deducted from the cost of the related property and equipment.

Foreign currency translation and change in reporting currency

The functional currency of the Company and two of its integrated subsidiaries (Protiva and Protiva USA), is the Canadian dollar, and the functional currency of Arbutus Inc. is the U.S. dollar. Foreign currency monetary assets and liabilities are translated into the functional currency at the rate of exchange prevailing at the balance sheet date. Non-monetary assets and

80



liabilities are translated at historical exchange rates. The previous month’s average rate of exchange is used to translate revenue and expense transactions. Exchange gains and losses are included in income or loss for the period.
The Company is using United States dollars as its reporting currency. All assets and liabilities are translated using the exchange rate at the balance sheet date. Revenues, expenses and other income (losses) are translated using the average rate for the period, except for large transactions, for which the exchange rate on the date of the transaction is used. Equity accounts are translated using the historical rate. As the translation differences from the Company’s functional currency of Canadian dollars to the Company’s reporting currency of US dollars are unrealized gains and losses, the differences are recorded in other comprehensive income (loss), and do not impact the calculation of Income or Loss per Share.

On January 1, 2016, the Company changed its functional currency from the Canadian dollar to the U.S. dollar based on management's analysis of the changes in the primary economic environment in which the Company operates. The change in functional currency is accounted for prospectively from January 1, 2016 and financial statements prior to and including the year-ended December 31, 2015 have not been restated for the change in functional currency.

Deferred income taxes

Income taxes are accounted for using the asset and liability method of accounting. Deferred income taxes are recognized for the future income tax consequences attributable to differences between the carrying values of assets and liabilities and their respective income tax bases and for loss carry-forwards. Deferred income tax assets and liabilities are measured using enacted income tax rates expected to apply to taxable income in the periods in which temporary differences are expected to be recovered or settled. The effect on deferred income tax assets and liabilities of a change in tax laws or rates is included in earnings in the period that includes the enactment date. When realization of deferred income tax assets does not meet the more-likely-than-not criterion for recognition, a valuation allowance is provided.
 
Stock-based compensation

The Company grants stock options to employees and directors pursuant to a share incentive plan described in note 6. Compensation expense is recorded for issued stock options using the fair value method with a corresponding increase in additional paid-in capital. Any consideration received on the exercise of stock options is credited to share capital.

The fair value of stock options is measured at the grant date and amortized on a straight-line basis over the vesting period.
 
Replacement awards

Replacement awards are share-based payment awards exchanged for awards held by employees of Arbutus Inc. As part of the Company’s acquisition of Arbutus Inc., Arbutus shares were exchanged for Arbutus Inc.’s shares subject to repurchase rights held by Arbutus Inc.’s employees - see note 3.

As at the date of acquisition of Arbutus Inc., the Company determined the total fair value of replacement awards and attributed a portion of the replacement awards to pre-combination service as part of the total acquisition consideration, and a portion to post-combination service, which is recognized as compensation expense over the expiry period of repurchase provision rights subsequent to the acquisition date.

The replacement awards consist of common shares that were issued at acquisition. Accordingly, as stock compensation expense related to these awards is recognized, share capital is increased by a corresponding amount. Replacement awards are excluded in the calculation of basic net income (loss) per share until the repurchase rights have expired.

Warrants

The Company accounts for the warrants under the authoritative guidance on accounting for derivative financial instruments indexed to, and potentially settled in, a company’s own stock, on the understanding that in compliance with applicable securities laws, the registered warrants require the issuance of registered securities upon exercise and do not sufficiently preclude an implied right to net cash settlement. The Company classifies warrants in its consolidated balance sheet as a liability which is revalued at each balance sheet date subsequent to the initial issuance. The Company uses the Black-Scholes pricing model to value the warrants. Determining the appropriate fair-value model and calculating the fair value of registered warrants requires considerable judgment. A small change in the estimates used may cause a relatively large change in the estimated valuation. The estimated volatility of the Company’s common stock at the date of issuance, and at each subsequent reporting period, is based on historic fluctuations in the Company’s stock price. The risk-free interest rate is based on the Government of

81



Canada rate for bonds with a maturity similar to the expected remaining life of the warrants at the valuation date. The expected life of the warrants is based on the historical pattern of exercises of warrants.

Segment information

The Company operates in a single reporting segment. Substantially all of the Company’s revenues to date were earned from customers or collaborators based in the United States. Substantially all of the Company’s premises, property and equipment are located in Canada and the United States.
 
Recent accounting pronouncements

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (FASB) or other standard setting bodies that are adopted by the Company as of the specified effective date. Unless otherwise discussed, we believe that the impact of recently issued standards that are not yet effective will not have a material impact on our financial position or results of operations upon adoption.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842): Recognition and Measurement of Financial Assets and Financial Liabilities. The update supersedes Topic 840, Leases and requires the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous GAAP. Topic 842 retains a distinction between finance leases and operating leases, with cash payments from operating leases classified within operating activities in the statement of cash flows. The amendments in this update are effective for fiscal years beginning after December 15, 2018 for public business entities, which for the Company means January 1, 2019. The Company does not plan to early adopt this update. The extent of the impact of this adoption has not yet been determined.

In September 2015, the FASB issued ASU 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments. The update eliminates the requirement to retrospectively adjust the provisional amounts recognized at the acquisition date with a corresponding adjustment to goodwill during the measurement period when new information is obtained about the facts and circumstances that existed as of the acquisition date, that if known, would have affected the measurement of the amounts initially recognized or would have resulted in the recognition of additional assets or liabilities. The amendments in this update are effective for fiscal years beginning after December 15, 2015, which for the Company means January 1, 2016, and should be applied prospectively to adjustments to provisional amounts that occur after the effective date of this update. Early application is permitted for financial statements that have not been issued. The Company has adopted this update and applied it to the acquisition of Arbutus Inc.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (ASC 606). The standard is intended to clarify the principles for recognizing revenue and to develop a common revenue standard for U.S. GAAP and IFRS by creating a new Topic 606, Revenue from Contracts with Customers. This guidance supersedes the revenue recognition requirements in ASC 605, Revenue Recognition, and supersedes some cost guidance included in Subtopic 605-35, Revenue Recognition - Construction-Type and Production-Type Contracts. The core principle of the accounting standard is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those good or services. The amendments should be applied by either (1) retrospectively to each prior reporting period presented; or (2) retrospectively with the cumulative effect of initially applying this ASU recognized at the date of initial application. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date to defer the effective date of Update 2014-09 for all entities by one year. The new guidance would be effective for fiscal years beginning after December 15, 2017, which for the Company means January 1, 2018. Entities are permitted to adopt in accordance with the original effective date if they choose. The Company has not yet determined the extent of the impact of adoption.
 
In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. The update is intended to provide guidance in GAAP about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. Under amendments to GAAP, the assessment period is within one year after the date that the financial statements are issued (or available to be issued). The amendments are effective for the annual period ending after December 15, 2016, which for the Company means January 1, 2017, and for annual periods and interim periods thereafter. Early application is permitted. The Company does not plan to early adopt this update. The extent of the impact of this adoption has not yet been determined.

3. Merger with Arbutus Biopharma, Inc. (formerly OnCore BioPharma, Inc.)
 
(a)      Purchase Price Allocation

On January 11, 2015, the Company entered into a Merger Agreement to acquire 100% of the outstanding shares of Arbutus Inc. (formerly OnCore Biopharma, Inc.) and its wholly-owned subsidiary, Enantigen (see note 9). Arbutus Inc. was a privately owned U.S. company focused on discovery, development and commercialization of an all-oral cure regimen for patients with HBV. The merger was approved by the Company’s shareholders on March 3, 2015 and closed on March 4, 2015. Arbutus Inc.’s results of operations and fair value of assets acquired and liabilities assumed are included in the Company’s consolidated financial statements from the date of acquisition.

The transaction has been accounted for using the acquisition method based on ASC 805, Business Combinations, with Arbutus (formerly Tekmira) identified as the acquirer, based on managements’ analysis and evaluation of the form of the acquisition, the relative contribution and rights of the predecessor groups post-closing, and the relative number of shares issued by the Company on acquisition of Arbutus Inc. Under the acquisition method, the consideration transferred is measured at fair value; common shares as consideration are issued at the market price as at the acquisition date. The excess of the purchase price over the preliminary fair value assigned to the net assets acquired has been recorded as goodwill. Acquisition costs were expensed as incurred. The Company recorded $9,656,000 of acquisition costs for the year ended December 31, 2015 (2014 - $462,000).

The Company issued consideration with a total fair value of $381,942,000 on acquisition. Of this consideration, 23,973,315 common shares were issued, which is comprised of 20,347,906 common shares issued without subjects and 3,625,412 common shares issued to Arbutus Inc.’s founding executives and subject to repurchase provisions. The fair value of the common shares issued without subjects has been determined to be the Company’s NASDAQ closing price of $18.26 on the date prior to the acquisition’s consummation, March 4, 2015. The total fair value of the common shares issued subject to repurchase provision has been determined to be $66,196,000, using the Black-Scholes pricing model with assumed risk-free interest rate of 0.74%, volatility of 81%, a zero dividend yield and an expected life of 4 years. Of the total fair value, $9,262,000 has been attributed as pre-combination service and included as part of the total acquisition consideration. The post-combination attribution of $56,934,000 will be recognized as compensation expense over the period of expiry of repurchase provision rights and is not included in the total acquisition consideration. In July 2015, in conjunction with amendments to the employment contracts of Arbutus Inc.’s founding executives, the Company amended the repurchase provision rights period of expiry from August 2018 to August 2017. This amendment results in an acceleration of compensation expense recognized in each subsequent period by approximately $1,900,000 per quarter, effective in Q3 2015. The Company recorded $16,687,000 in stock-based compensation expense related to services performed during the period of expiration of repurchase provision rights from the acquisition date through to December 31, 2015.

As at the acquisition date, 3,625,412 shares were issued and outstanding which were and continue to remain subject to a repurchase provision. Subsequent to the acquisition date and the July 2015 amendment to the repurchase provision rights, the rights expire at a rate of 302,120 on November 30, 2015 and February 29, 2016 and at a rate of 503,552 shares every three months thereafter commencing May 31, 2016.

The Company has further reserved 184,332 shares for the future exercise of Arbutus Inc. stock options. The total fair value of Arbutus Inc. stock options at the date of acquisition has been determined to be $3,287,000, using the Black-Scholes pricing model with an assumed risk-free interest rate of 0.97%, volatility of 78%, a zero dividend yield and an expected life of 8 years, which are consistent with the assumption inputs used by the Company to determine the fair value of its options. Of the total fair value, $1,127,000 has been attributed as pre-combination service and included as part of the total acquisition consideration. The post-combination attribution of $2,160,000 will be recognized as compensation expense over the vesting period of the stock options through to December 2018. The Company has included $463,000 compensation expense related to the vesting of Arbutus Inc. stock options from the acquisition date through to December 31, 2015.

The aggregate fair value of consideration transferred to acquire Arbutus Inc.’s outstanding shares has been determined to be $381,942,000, and has been attributed to fair values of assets acquired and liabilities assumed. The Company has refined the preliminary allocation of the purchase price for intangible assets, goodwill, contingent consideration and deferred tax liability from what was disclosed in prior periods. The following table summarizes the Company’s finalized purchase price allocation as at December 31, 2015:

The fair value of intangible assets is estimated to be $391,649,000. The fair value of each IPR&D asset is estimated using the income approach. The income approach uses valuation techniques to discount future economic benefits attributed to the subject intangible asset to a present value. Present value is based on current market expectations about those future amounts and includes management’s estimates of risk-adjusted future incremental earnings that may be achieved upon regulatory approval, promotion, and distribution associated with the rights and includes estimated cash flows of approximately 20 years and a discount rate of approximately 13.7%. The identifiable intangible assets acquired consist of in-process research and development (IPR&D) HBV assets, as summarized in the table below:

IPR&D – Cyclophilins
$
39,007

IPR&D – Immune Modulators
183,103

IPR&D – Antigen Inhibitors
36,437

IPR&D – cccDNA Sterilizers
133,102

Total IPR&D
$
391,649


All IPR&D acquired is currently classified as indefinite-lived and is not currently being amortized. IPR&D becomes definite-lived upon the completion or abandonment of the associated research and development efforts, and will be amortized from that time over an estimated useful life based on respective patent terms. The fair value of each IPR&D asset will continue to be evaluated on a quarterly basis for indicators of impairment.

Based on the fair values above, an amount of $162,514,000 has been allocated to goodwill, which represents the excess of the purchase price over the fair values assigned to the net assets acquired. Goodwill is attributable to synergies expected to arise after the Company’s acquisition of Arbutus Inc. The full amount of the value of goodwill has been assigned to the entire Company, since management has determined that the Company has only one reporting unit. The goodwill is not deductible for tax purposes, and is not amortized, but will be evaluated for impairment on an annual basis or more often if the Company identifies impairment indicators that would require earlier testing.

Reconciliation of preliminary to final purchase price allocation

During the year ended December 31, 2015, the Company finalized the purchase price allocation and made revisions to certain preliminary estimated fair values of assets acquired and liabilities assumed. The following table presents a summary of revisions and adjustments made to the preliminary estimates as previously disclosed to the finalized purchase price allocation:

The preliminary purchase price as of the acquisition date of March 4, 2015 as previously disclosed in the notes to consolidated financial statements included in the Company's Quarterly Report on Form 10-Q for the period ended March 31, 2015.
2.
The measurement period is from the acquisition date of March 4, 2015 to the date the Company finalized the purchase price allocation on December 31, 2015.

The measurement period adjustment for intangible assets acquired was made as the Company revised certain royalty rates on future sales of various intangible assets acquired. This resulted in an increase in deferred income tax liability associated with the intangible assets. In addition, the Company revised its preliminary tax rate based on management's revised analysis of a combined federal and state tax rate in the jurisdiction in which the Company expects the deferred tax liability to be settled or realized.

The measurement period adjustment for other non-current liabilities relate to the contingent consideration payable to former Enantigen shareholders upon the achievement of certain regulatory, development and sales milestones, as described in note 9. The adjustment relates to management's revision to the probabilities used in a probability weighted assessment of the likelihood of milestones being met and timing of such payments.

Based on the above measurement period adjustments, the increase to goodwill of $6,649,000 results in a final goodwill allocation of $162,514,000. As described in note 2 and further below, the Company conducts its annual goodwill impairment test on December 31st.

Pro forma information

The amount of net loss of Arbutus Inc. included in the consolidated statements of operations from the acquisition date, through the period ended December 31, 2015 was $13,658,000. Arbutus Inc. did not earn any revenues from the acquisition date through the year-ended December 31, 2015.

The following table presents the unaudited pro forma results for the year ended December 31, 2015 and 2014. The pro forma financial information combines the results of operations of Arbutus, Arbutus Inc., Protiva, Protiva USA, and Enantigen as though the businesses had been combined as of the beginning of fiscal 2014. The pro forma financial information is presented for informational purposes only, and is not indicative of the results of operations that would have been achieved if the merger had taken place at the beginning of fiscal 2014. The pro forma financial information presented includes acquisition costs, amortization charges for acquired tangible assets, impairment charge on acquired intangible assets (as described in note 3b below), but does not include amortization charges for acquired intangible assets as these assets have not yet been put in use.

(b)      Impairment evaluations for intangible assets and goodwill

The Company evaluates the recoverable amount of intangible assets on an annual basis and performs an annual evaluation of goodwill as of December 31 each year, unless there is an event or change in the business that could indicate impairment and earlier testing.

Impairment of intangible assets

On October 28, 2015, the Company announced that the development of the cyclophilin drug candidate, OCB-030 has been discontinued. The decision was based on extensive preclinical evaluations performed by the Company of OCB-030 and other competitive cyclophilin inhibitors following the acquisition of Arbutus Inc., which concluded that cyclophilins do not play a meaningful role in HBV biology. Although the final conclusion was made subsequent to the period end, it reflected management’s best estimate as at September 30, 2015, and as such, the Company recorded an estimated impairment charge of $37,990,000 and a corresponding income tax benefit of $15,196,000 related to the decrease in deferred tax liability for the discontinuance of OCB-030 in the consolidated statement of operations and comprehensive loss.

As noted above, the Company finalized its purchase price allocation during the fourth quarter of 2015 by making certain revisions to estimates which included adjustments to the fair value of individual intangible assets acquired. The fair value of cyclophilin inhibitors has been adjusted to be $39,007,000 as compared to management's best estimate of $37,990,000 previously written off in the third quarter. The incremental adjustment to fair value of $1,017,000 as well as the corresponding incremental adjustment to income tax benefit of $989,000 are cumulatively reflected in the Company's consolidated statement of operations and comprehensive loss for the year-ended December 31, 2015. For all other IPR&D, fair values of the intangible assets were calculated to be above the respective carrying values; therefore, no impairment was recorded. The following table summarizes the carrying values, net of impairment of the intangible assets as at December 31, 2015:

IPR&D – Cyclophilins
$

IPR&D – Immune Modulators
183,103

IPR&D – Antigen Inhibitors
36,437

IPR&D – cccDNA Sterilizers
133,102

Total IPR&D
$
352,642


Annual impairment evaluation of goodwill

On December 31, the Company conducted its annual impairment evaluation of goodwill. Goodwill was recorded as a result of the acquisition of Arbutus Inc. as described in note 3(a), and has a carrying value of $162,514,000. As part of the evaluation of the recoverability of goodwill, the Company has identified only one reporting unit to which the total carrying amount of goodwill has been assigned. The income approach is used to estimate the fair value of the reporting unit, which requires estimating future cash flows and risk-adjusted discount rates. Changes in these estimates and assumptions could materially affect the determination of fair value of the reporting unit and may result in impairment charges in future periods.







86



As at December 31, 2015, the fair value of the reporting unit exceeded the carrying value of the reporting unit, and as such the second step of the impairment test, which measures the amount of impairment charge, was not required. In addition to the income approach, the Company considered the market capitalization of approximately $242,844,000 as at December 31, 2015. Although the Company’s carrying value of $547,679,000 exceeded the market capitalization, the Company reconciled the income approach determination of fair value with the market capitalization by considering macroeconomic factors, and as such, the Company does not believe that market capitalization appropriately reflected the value of the Company for the purpose of testing goodwill impairment. No impairment charge on goodwill was recorded for the year ended December 31, 2015.

(a)      Contract with United States Government’s Department of Defense (“DoD”) to develop TKM-Ebola

On July 14, 2010, the Company signed a contract with the DoD to advance TKM-Ebola, an RNAi therapeutic utilizing the Company’s lipid nanoparticle technology to treat Ebola virus infection.

In the initial phase of the contract, funded as part of the Transformational Medical Technologies program, the Company was eligible to receive up to $34,700,000. This initial funding was for the development of TKM-Ebola including completion of preclinical development, filing an Investigational New Drug application with the United States Food and Drug Administration (“FDA”) and completing a Phase 1 human safety clinical trial. On May 8, 2013, the Company announced that the contract had been modified to support development plans that integrate recent advancements in lipid nanoparticle (“LNP”) formulation and manufacturing technologies. The contract modification increased the stage one targeted funding by an additional $6,970,000. On April 22, 2014, the Company and the DoD signed a contract modification to further increase the stage one targeted funding by $2,100,000 to $43,819,000. The additional funding was to compensate the Company for unrecovered overheads related to the temporary stop-work period that occurred in 2012 and to provide additional overhead funding should it be required.

The DoD had the option of extending the contract beyond the initial funding period to support the advancement of TKM-Ebola through to the completion of clinical development and FDA approval. Based on the contract’s budget this would have provided the Company with up to $140,000,000 in funding for the entire program. In December 2014, the DoD exercised an option valued at $7,000,000 to manufacture TKM-Ebola-Guinea, developed by the Company targeting the Ebola-Guinea strain responsible for the current outbreak in West Africa.

Under the contract, the Company is reimbursed for costs incurred, including an allocation of overhead costs, and is paid an incentive fee. At the beginning of the fiscal year, the Company estimates its labor and overhead rates for the year ahead. At the end of the year the actual labor and overhead rates are calculated and revenue is adjusted accordingly. The Company’s actual labor and overhead rates will differ from its estimated rates based on actual costs incurred and the proportion of the Company’s efforts on contracts and internal products versus indirect activities. Within minimum and maximum collars, the amount of incentive fee the Company can earn under the contract varies based on costs incurred versus budgeted costs.  During the contractual period, incentive fee revenue and total costs are impacted by management’s estimate and judgments which are continuously reviewed and adjusted as necessary using the cumulative catch-up method.  For the years ended December 31, 2014 and 2015, the Company believes it can reliably estimate the final contract costs so has recognized the portion of expected incentive fee which has been earned to date.

On October 1, 2015, the Company received formal notification from the DoD that, due to the unclear development path for TKM-Ebola and TKM-Ebola-Guinea, the Ebola-Guinea Manufacturing and the Ebola-Guinea IND submission statements of work had been terminated, subject to the completion of certain post-termination obligations.  The TKM-Ebola portion of the contract was completed in November 2015. The Company is currently conducting contract close out procedures with the DoD.

(b)      Option and Services Agreements with Monsanto Company (“Monsanto”)

On January 13, 2014, the Company and Monsanto signed an Option Agreement and a Services Agreement (together, the “Agreements”). Under the Agreements, Monsanto has an option to obtain a license to use the Company’s proprietary delivery technology and related intellectual property for use in agriculture. Over the option period, which is expected to be approximately four years, the Company will provide lipid formulations for Monsanto’s research and development activities, and Monsanto will make certain payments to the Company to maintain its option rights. The maximum potential value of the transaction is $86,200,000 following the successful completion of milestones.

In May 2015, the arrangement was amended to extend the option period by approximately five months, with payments up to $2,000,000 for the extension period. From inception of the contract to December 31, 2015, the Company had received $19,300,000 from Monsanto. The amounts received relate to research services and use of the Company’s technology over the option period, and are recognized as revenue on a straight-line basis over the extended option period.

Following the completion of the Phase A extension period in October 2015, no further research activities were conducted under the arrangement, as Monsanto did not elect to proceed to Phase B of the research plan. As such, the Company revised its estimate of the option period, over which payments received from Monsanto is recognized as revenue, to be from inception to December 31, 2015 as the Company believes it no longer has any further obligations to provide future research activities to Monsanto. This resulted in the full release of Monsanto deferred revenue and a recognition of $14,981,000 in Monsanto revenue for the year-ended December 31, 2015.

88




Under the Agreements, the Company has established a wholly-owned subsidiary, PADCo. The Company has determined that PADCo is a variable interest entity (“VIE”); however, Monsanto is the primary beneficiary of the arrangement. PADCo was established to perform research and development activities, which have been funded by Monsanto in return for a call option to acquire the equity or all of the assets of PADCo. At any time during the option period, Monsanto may choose to exercise its option, in which case Monsanto would pay the Company an option exercise fee and would receive a worldwide, exclusive right to use the Company’s proprietary delivery technology in the field of agriculture. Monsanto may elect to terminate this option at their discretion. The Company retains all rights to therapeutics uses of all current intellectual property and intellectual property developed under the Agreements. The Company’s initial investment is not significant, and the Company has no implied or unfunded commitments and the maximum exposure to loss is limited to the amount of investment in the entity. The Company has included its investment in PADCo in other assets. There were no significant assets or liabilities for PADCo as at December 31, 2015. There was no equity income or loss with respect to PADCo recorded for the periods ended December 31, 2014 and December 31, 2015. In March 2016, Monsanto exercised its option to acquire 100% of the outstanding shares of PADCo and will pay the Company an exercise fee of $1,000,000 - refer to note 13 for the subsequent event.

(c)      License and collaboration with Alnylam Pharmaceuticals, Inc. (Alnylam) and Acuitas Therapeutics Inc. (Acuitas) 

Milestone receipts and payments

In November 2013, Alnylam initiated a Phase III trial with ALN-TTR02, also known as patisiran, and the associated $5,000,000 development milestone was paid to the Company in December 2013. In addition, the Company earned a $150,000 milestone in March 2014 from Acuitas (formerly AlCana Technologies, Inc.) subsequent to Acuitas receiving a milestone payment from Alnylam with respect to Alnylam initiating a Phase III trial for ALN-TTR02.

In November 2013, the Company initiated Phase I/II clinical trial for TKM-PLK1, resulting in a milestone payment of $375,000 to Alnylam.

Arbitration with Alnylam and Ascletis Pharmaceuticals (Hangzhou) Co. Ltd. (“Ascletis”)

On June 21, 2013, the Company transferred manufacturing process technology to Ascletis to enable them to produce ALN-VSP, a product candidate licensed to them by Alnylam. The Company believed that under its licensing agreement with Alnylam, the technology transfer to Ascletis triggered a $5,000,000 milestone obligation from Alnylam to the Company. However, Alnylam demanded a declaration that the Company had not yet met its milestone obligations. The Company disputed Alnylam’s position. To remedy this dispute, the Company and Alnylam commenced arbitration proceedings as provided for under the agreement.  The hearing date for this arbitration took place in May 2015, and in March 2016, the arbitration proceeding with Alnylam has concluded resulting in no milestone payment to the Company.  The Company has not recorded any revenue in respect of this milestone for the year-ended December 31, 2015.
 
(d)      Bristol-Myers Squibb (“BMS”) collaboration

On May 10, 2010 the Company announced the expansion of its research collaboration with BMS. Under the new agreement, BMS uses small interfering RNA (“siRNA”) molecules formulated by the Company in LNP technology to silence target genes of interest.  BMS is conducting the preclinical work to validate the function of certain genes and share the data with the Company.  The Company can use the preclinical data to develop RNAi therapeutic drugs against the therapeutic targets of interest.  The Company received $3,000,000 from BMS concurrent with the signing of the agreement and recorded the amount as deferred revenue. The Company is required to provide a pre-determined number of LNP batches over the four-year agreement.  BMS has a first right to negotiate a licensing agreement on certain RNAi products developed by the Company that evolve from BMS validated gene targets.

Revenue from the May 10, 2010 agreement with BMS is being recognized as the Company produces the related LNP batches.

Revenue earned for the year-ended December 31, 2014 relates to batches shipped to BMS during the period. In August 2014, the agreement expired and both companies' obligations under the agreement ended.

(e)      License and Development and Supply Agreement with Dicerna Pharmaceuticals, Inc. (“Dicerna”)

On November 16, 2014, the Company signed a License Agreement and a Development and Supply Agreement (together, the “Agreements”) with Dicerna to development, manufacture, and commercialization of products directed to treatment of Primary Hyperoxaluria 1 (“PH1”), In consideration for the rights granted under the Agreements, Dicerna paid the Company an upfront cash payment of $2,500,000. The Company is also entitled to receive payments from Dicerna on the manufacturing and services provided, as well as further payments with the achievement of development and regulatory milestones of $22,000,000 in aggregate, and potential commercial royalties. Further, under the Agreements, a joint development committee has been established to provide guidance and direction on the progression of the collaboration.

The Company determined the deliverables under the Agreements included the rights granted, participation in the joint development committee, materials manufactured and other services provided, as directed under the joint development committee. The license and participation in the joint development committee have been determined by the Company to not have standalone value due to the uniqueness of the subject matter under the Agreements. Therefore, these deliverables are treated as one unit of accounting and recognized as revenue over the performance period, which the Company has estimated to be approximately 28 months as at December 31, 2015.

The Company has determined that manufacturing services and other services provided have standalone value, as a separate statement of work is executed and invoiced for each manufacturing or service work order. The relative fair values are determined as a batch price or fee is estimated upon the execution of each work order, with actual expenditures charged at comparable market rates with embedded margins on each work order.

Manufacturing work orders are invoiced at the time of execution of the work order, at the initiation of manufacture, and at the release of materials. The Company has deferred the recognition of revenue on all cash deposit payments received for manufacturing work orders until acceptance of inventory.  Revenue from service work orders is recognized as the services are performed.

The Company believes the development and regulatory milestones are substantive, due to the existence of substantive uncertainty upon the execution of the arrangement, and that the achievement of the development and regulatory events are based in part on the Company’s performance and the occurrence of a specific outcome resulting from performance. The Company has not received any milestone payments to date.

(f)      Agreements with Spectrum Pharmaceuticals, Inc. (“Spectrum”)

On May 6, 2006, the Company signed a number of agreements with Talon Therapeutics, Inc. (“Talon”, formerly Hana Biosciences, Inc.) including the grant of worldwide licenses (the “Talon License Agreement”) for three of the Company’s chemotherapy products, Marqibo®, Alocrest ™ (Optisomal Vinorelbine) and Brakiva ™ (Optisomal Topotecan).

On August 9, 2012, the Company announced that Talon had received accelerated approval for Marqibo from the FDA for the treatment of adult patients with Philadelphia chromosome negative acute lymphoblastic leukemia in second or greater relapse or whose disease has progressed following two or more anti-leukemia therapies. Marqibo is a liposomal formulation of the chemotherapy drug vincristine. In the year ended December 31, 2012, the Company received a milestone of $1,000,000 based on the FDA’s approval of Marqibo and will receive royalty payments based on Marqibo’s commercial sales. There are no further milestones related to Marqibo but the Company is eligible to receive total milestone payments of up to $18,000,000 on Alocrest and Brakiva.

The value of the Company’s warrants are particularly sensitive to changes in the Company’s share price and the estimated share price volatility.

(d)      Stock-based compensation

The Company has six share-based compensation plans; the “2007 Plan”, the “2011 Plan”, two “Designated Plans” (together, the “Arbutus Plans”), the “Protiva Option Plan”, and the "OnCore Option Plan" (see note 3 above).

On June 22, 2011, the shareholders of the Company approved an omnibus stock-based compensation plan (the “2011 Plan”). The Company’s pre-existing 2007 Plan was limited to the granting of stock options as equity incentive awards whereas the 2011 Plan also allows for the issuance of tandem stock appreciation rights, restricted stock units and deferred stock units (collectively, and including options, referred to as “Awards”). The 2011 Plan replaces the 2007 Plan. The 2007 Plan will continue to govern the options granted thereunder. No further options will be granted under the Company’s 2007 Plan.

Under the Company’s 2007 Plan the Board of Directors granted options to employees, directors and consultants of the Company.  The exercise price of the options was determined by the Company’s Board of Directors but was always at least equal to the closing market price of the common shares on the day preceding the date of grant and the term of options granted did not exceed 10 years.  The options granted generally vested over three years for employees and immediately for directors.

Under the Company’s 2011 Plan the Board of Directors may grant options, and other types of Awards, to employees, directors and consultants of the Company.  The exercise price of the options is determined by the Company’s Board of Directors but will be at least equal to the closing market price of the common shares on the day preceding the date of grant and the term may not exceed 10 years.  Options granted generally vest over three years for employees and immediately for directors.


92



Additionally, the Company granted a total of 200,000 options in 2013 to two executive officers in conjunction with their new appointments as executive officers. These options were granted in accordance with the policies of the Toronto Stock Exchange and pursuant to newly designated share compensation plans (the “Designated Plans”). The Designated Plans are governed by substantially the same terms as the 2011 Plan. Hereafter, information on options governed by the 2007 Plan, the 2011 Plan, and the Designated Plans is presented on a consolidated basis as the terms of the four plans are similar. Information on the Protiva Option Plan and the OnCore Option Plan is presented separately.

At the Company’s annual general and special meeting of shareholders on May 8, 2014 and July 9, 2015, the shareholders of the Company approved respectively, a 800,000 and a 3,500,000 increase in the number of stock-based compensation awards that the Company is permitted to issue.

Valuation assumptions for the Arbutus Plans

On March 3, 2015, the Company de-listed from the Toronto Stock Exchange. All stock options granted after March 3, 2015 were denominated in US dollars based on the Company's stock price on the NASDAQ. The methodology and assumptions used to estimate the fair value of stock options at date of grant under the Black-Scholes option-pricing model remain unchanged. Assumptions on the dividend yield are based on the fact that the Company has never paid cash dividends and has no present intention to pay cash dividends. Assumptions about the Company’s expected stock-price volatility are based on the historical volatility of the Company’s publicly traded stock. The risk-free interest rate used for each grant is equal to the zero coupon rate for instruments with a similar expected life. Expected life assumptions are based on the Company’s historical data. Based on an analysis of its historical forfeitures, the Company has applied a forfeiture rate to all unvested options held as of December 31, 2015. The Company will record additional expense if the actual forfeitures are lower than estimated and will record a recovery of prior expense if the actual forfeitures are higher than estimated. The weighted average option pricing assumptions and the resultant fair values are as follows:

Protiva Option Plan

On May 30, 2008, as a condition of the acquisition of Protiva Biotherapeutics Inc., a total of 350,457 common shares of the Company were reserved for the exercise of 519,073 Protiva share options (“Protiva Options”). The Protiva Options have an exercise price of C$0.30, were fully vested and exercisable as of May 30, 2008. As at December 31, 2015, the outstanding options expire at various dates from April 3, 2017 to March 1, 2018 and upon exercise each option will be converted into approximately 0.6752 shares of the Company (the same ratio at which Protiva common shares were exchanged for Company common shares at completion of the acquisition of Protiva). The Protiva Options are not part of the Arbutus Plans and the Company is not permitted to grant any further Protiva Options.

The weighted average remaining contractual life of exercisable Protiva Options as at December 31, 2015 was 1.8 years.

The aggregate intrinsic value of Protiva Options outstanding at December 31, 2015 was $187,000. The intrinsic value of Protiva Options exercised in the year ended December 31, 2015 was $1,249,000 (2014 - $378,000; 2013 -$8,000).

OnCore Option Plan

As described in note 3 above, as at the acquisition date, the Company reserved 184,332 shares for the future exercise of OnCore (Arbutus Inc.) stock options. The total fair value of OnCore stock options at the date of acquisition has been determined to be $3,287,000, using the Black-Scholes pricing model with an assumed risk-free interest rate of 0.97%, volatility of 78%, a zero dividend yield and an expected life of 8 years, which are consistent with the assumption inputs used by the Company to determine the fair value of its options. Of the total fair value, $1,127,000 has been attributed as pre-combination service and included as part of the total acquisition consideration. The post-combination attribution of $2,160,000 will be recognized as compensation expense over the vesting period of the stock options through to December 2018.

Following the merger, the Company is not permitted to grant any further options under the OnCore Option Plan. The Company has included $463,000 of compensation expense related to the vesting of Arbutus Inc. stock options from the acquisition date through to December 31, 2015, which includes an estimated forfeiture rate consistent with the Company's forfeiture estimate under the Arbutus Plans.

96




(a) Government grants

On December 22, 2014, the Company entered into a Manufacturing and Clinical Trial Agreement with the University of Oxford to provide the new TKM-Ebola-Guinea therapeutic product for clinical studies in West Africa. The University of Oxford is the representative of the International Severe Acute Respiratory and Emerging Infection Consortium (ISARIC), who conducted clinical studies of TKM-Ebola-Guinea in Ebola virus infected patients, with funding provided by the Wellcome Trust. In January 2015, the Company received $1,098,000 from ISARIC for materials manufactured and used in the March 2015 TKM-Ebola-Guinea Phase II single arm trial conducted in Sierra Leone. In June 2015, the Company announced closing of the enrollment for the trial as it reached a futility boundary, which was a predefined statistical endpoint. No further funding is expected under this grant.

Government grants for the year ended December 31, 2015 include $1,245,000 in funding from the U.S. National Institutes of Health (2014 - $172,000).

(b) Refundable investment tax credits

The Company’s estimated claim for refundable Scientific Research and Experimental Development investment tax credits for the year ended December 31, 2015 is $196,000 (2014 - $52,000).

8. Income taxes

Income tax (recovery) expense varies from the amounts that would be computed by applying the combined Canadian federal and provincial income tax rate of 26% (2014 - 26%; 2013 – 26%) to the loss before income taxes as shown in the following tables:

As at December 31, 2015, the Company has investment tax credits available to reduce Canadian federal income taxes of $7,969,000 (December 31, 2014 - $7,866,000) and provincial income taxes of $3,869,000 (December 31, 2014 - $3,401,000), expiring between 2027 and 2035. In addition, the Company has research and development credits of $483,000 available for indefinite carry-forward, which can be used to reduce future taxable income in the U.S.

At December 31, 2015, the Company has scientific research and experimental development expenditures of $51,823,000 (December 31, 2014 - $49,907,000) available for indefinite carry-forward and $24,745,000 (December 31, 2014 - $25,301,000) of net operating losses due to expire between 2027 and 2035 and which can be used to offset future taxable income in Canada.

As at December 31, 2015, the Company has $17,235,000 of net operating losses due to expire between 2030 and 2035, which can be used to offset future taxable income in the U.S. Future use of a portion of the U.S. loss carry-forwards is subject to limitations under the Internal Revenue Code Section 382. As a result of ownership changes occurred on October 1, 2014 and March 4, 2015, the Company's ability to use these losses may be limited. Losses incurred to date may be further limited if a subsequent change in control occurs.

On November 23, 2011, the Company was registered as a corporation under the Business Activity Act in the province of British Columbia. Under this program, provincial corporation tax charged on foreign income earned from the Company’s patents will be eligible for a 75% tax refund up to a maximum of C$8,000,000. Significant components of the Company’s deferred tax assets are shown below:

The comparative figures in the above table have been recast to increase the deferred tax assets before valuation allowance by $8,424,000 and the valuation allowance by $8,424,000 as at December 31, 2014 to be consistent with current year's disclosure. The comparative figures in the income tax expense reconciliation table have also been recast to reflect these changes. These adjustments have no impact on the consolidated financial position, consolidated results of operations or the consolidated cash flows.

Product development partnership with the Canadian Government

The Company entered into a Technology Partnerships Canada (TPC) agreement with the Canadian Federal Government on November 12, 1999.  Under this agreement, TPC agreed to fund 27% of the costs incurred by the Company, prior to March 31, 2004, in the development of certain oligonucleotide product candidates up to a maximum contribution from TPC of $7,179,000 (C$9,330,000).  As at December 31, 2015, a cumulative contribution of $2,675,000 (C$3,702,000) had been received and the Company does not expect any further funding under this agreement.  In return for the funding provided by TPC, the Company agreed to pay royalties on the share of future licensing and product revenue, if any, that is received by the Company on certain non-siRNA oligonucleotide product candidates covered by the funding under the agreement.  These royalties are payable until a certain cumulative payment amount is achieved or until a pre-specified date.  In addition, until a cumulative amount equal to the funding actually received under the agreement has been paid to TPC, the Company agreed to pay 2.5% royalties on any royalties the Company receives for Marqibo. For the year ended December 31, 2015, the Company earned royalties on Marqibo sales in the amount of $240,000 (see note 4(f)), resulting in $6,000 recorded by the Company as royalty payable to TPC (2014 - $190,000; 2013 -$1,000). The cumulative amount paid or accrued up to December 31, 2015 was $12,000, resulting in the contingent amount due to TPC being $2,664,000 (C$3,687,000).

License agreement with Marina Biotech, Inc. (“Marina”)

On November 29, 2012 the Company announced a worldwide, non-exclusive license to a novel RNAi payload technology called Unlocked Nucleobase Analog (“UNA”) from Marina for the development of RNAi therapeutics.

UNA technology can be used in the development of RNAi therapeutics, which treat disease by silencing specific disease causing genes. UNAs can be incorporated into RNAi drugs and have the potential to improve them by increasing their stability and reducing off-target effects.

Under the license agreement the Company paid Marina an upfront fee of $300,000. A further license payment of $200,000 was paid in 2013 and the Company will make milestone payments of up to $3,250,000 and royalties on each product developed by the Company that uses Marina’s UNA technology. The payments to Marina are expensed to research, development, collaborations and contracts expense.

Effective August 9, 2013, Marina’s UNA technology was acquired by Arcturus Therapeutics, Inc. (“Arcturus”) and the UNA license agreement between the Company and Marina was assigned to Arcturus. The terms of the license are otherwise unchanged. On December 22, 2014, the Company received clearance from Health Canada to conduct a Phase I Clinical Study with TKM-HBV, which utilizes Arcturus’ UNA technology. The dosing of first subject in the Phase I clinical trial of TKM-HBV occurred in January 2015, which resulted in a milestone payment of $250,000 to Arcturus.
 
Arbitration with the University of British Columbia (“UBC”)

Certain early work on lipid nanoparticle delivery systems and related inventions was undertaken at UBC.  These inventions are licensed to the Company by UBC under a license agreement, initially entered in 1998 as amended in 2001, 2006 and 2007. The Company has granted sublicenses under the UBC license to Alnylam as well as to Talon.  Alnylam has in turn sublicensed back to the Company under the licensed UBC patents for discovery, development and commercialization of RNAi products. In 2009, the Company entered into a supplemental agreement with UBC, Alnylam and Acuitas, in relation to a separate research collaboration to be conducted among UBC, Alnylam and Acuitas to which the Company has license rights. The settlement agreement signed in late 2012 to resolve the litigation among the Company, Alnylam, and Acuitas, provided for the effective termination of all obligations under such supplemental agreement as between and among all litigants (see note 4(c)).

On November 10, 2014, UBC filed a notice of arbitration against the Company and on January 16, 2015, filed a Statement of Claim, which alleges entitlement to $3,500,000 in allegedly unpaid royalties based on publicly available information, and an unspecified amount based on non-public information. UBC also seeks interest and costs, including legal fees. The Company is currently disputing UBC’s allegations, and no dates have been scheduled for this arbitration. However, the Company notes that arbitration is subject to inherent uncertainty and an arbitrator could rule against the Company. The Company has not recorded an estimate of the possible loss associated with this arbitration, due to the uncertainties related to both the likelihood and amount of any possible loss or range of loss. However, the defense of arbitration and related matters are costly and may divert the attention of the Company’s management and other resources that would otherwise be engaged in other activities. Costs related to the arbitration have been recorded by the Company as incurred.

Contingent consideration from OnCore acquisition of Enantigen and License Agreements between Enantigen and Blumberg and Drexel
 
In October 2014, OnCore acquired all of the outstanding shares of Enantigen pursuant to a stock purchase agreement. Through this transaction, OnCore acquired a HBV surface antigen secretion inhibitor program and a capsid assembly inhibitor program, each of which are now assets of Arbutus, following the Company’s merger with Arbutus Inc. - see note 3.
 
Under the stock purchase agreement, OnCore agreed to pay up to a total of $21,000,000 to Enantigen’s selling stockholders upon the achievement of certain triggering events related to Enantigen’s two programs in pre-clinical development related to HBV therapies. The first triggering event is the enrollment of first patient in Phase 1b clinical trial in HBV patients, which the Company does not expect to occur in the next twelve-month period.

The regulatory, development and sales milestone payments have an estimated fair value of approximately $6,727,000 as at the date of acquisition of Arbutus Inc., and have been treated as contingent consideration payable in the purchase price allocation (note 3), based on information available at the date of acquisition, using a probability weighted assessment of the likelihood the milestones would be met and the estimated timing of such payments, and then the potential contingent payments were discounted to their present value using a probability adjusted discount rate that reflects the early stage nature of the development program, time to complete the program development, and overall biotech indices.

99



 
Contingent consideration is considered as a financial liability, and measured at its fair value at each reporting period with any changes in fair value from the previous reporting period recorded in the statement of operations and comprehensive loss. For the period ended December 31, 2015, the Company performed an evaluation of the fair value of the contingent consideration using the probability weighted assessment of likelihood of milestone payments as described above. The Company determined the fair value of the contingent consideration has increased by $770,000 to $7,497,000 and the increase in fair value has been recorded in other losses in the statement of operations and comprehensive loss for the year-ended December 31, 2015.

Drexel and Blumberg

In February 2014, OnCore entered into a license agreement with Blumberg and Drexel that granted an exclusive, worldwide, sub-licensable license to three different compound series: cccDNA inhibitors, capsid assembly inhibitors and HCC inhibitors.
 
In partial consideration for this license, OnCore paid a license initiation fee of $150,000 and issued warrants to Blumberg and Drexel. Under this license agreement, OnCore also agreed to pay up to $3,500,000 in development and regulatory milestones per licensed compound series, up to $92,500,000 in sales performance milestones per licensed product, and royalties in the mid-single digits based upon the proportionate net sales of licensed products in any commercialized combination. The Company is obligated to pay Blumberg and Drexel a double digit percentage of all amounts received from the sub-licensees, subject to customary exclusions.
 
In November 2014, OnCore entered into an additional license agreement with Blumberg and Drexel pursuant to which it received an exclusive, worldwide, sub-licensable license under specified patents and know-how controlled by Blumberg and Drexel covering epigenetic modifiers of cccDNA and STING agonists. In consideration for these exclusive licenses, OnCore made an upfront payment of $50,000. Under this agreement, the Company will be required to pay up to $1,000,000 for each licensed product upon the achievement of a specified regulatory milestone and a low single digit royalty, based upon the proportionate net sales of compounds covered by this intellectual property in any commercialized combination. The Company is also obligated to pay Blumberg and Drexel a double digit percentage of all amounts received from its sub-licensees, subject to exclusions.
 
Research Collaboration and Funding Agreement with Blumberg

In October 2014, Arbutus Inc. entered into a research collaboration and funding agreement with Blumberg under which the Company will provide $1,000,000 per year of research funding for three years, renewable at the Company’s option for an additional three years, for Blumberg to conduct research projects in HBV and liver cancer pursuant to a research plan to be agreed upon by the parties. Blumberg has exclusivity obligations to Arbutus with respect to HBV research funded under the agreement. In addition, the Company has the right to match any third party offer to fund HBV research that falls outside the scope of the research being funded under the agreement. Blumberg has granted the Company the right to obtain an exclusive, royalty bearing, worldwide license to any intellectual property generated by any funded research project. If the Company elects to exercise its right to obtain such a license, the Company will have a specified period of time to negotiate and enter into a mutually agreeable license agreement with Blumberg. This license agreement will include the following pre negotiated upfront, milestone and royalty payments: an upfront payment in the amount of $100,000; up to $8,100,000 upon the achievement of specified development and regulatory milestones; up to $92,500,000 upon the achievement of specified commercialization milestones; and royalties at a low single to mid-single digit rates based upon the proportionate net sales of licensed products from any commercialized combination.
 
NeuroVive Pharmaceutical AB (“NeuroVive”)
 
In September 2014, Arbutus Inc. entered into a license agreement with NeuroVive that granted them an exclusive, worldwide, sub-licensable license to develop, manufacture and commercialize, for the treatment of HBV, oral dosage form sanglifehrin based cyclophilin inhibitors (including OCB-030). Under this license agreement, the Company has been granted a non-exclusive, royalty free right and license and right of reference to NeuroVive’s relevant regulatory approvals and filings for the sole purpose of developing, manufacturing and commercializing licensed products for the treatment of HBV. Under this license agreement, the Company has (1) an option to expand its exclusive license to include treatment of viral diseases other than HBV and (2) an option, exercisable upon specified conditions, to expand its exclusive license to include development, manufacture and commercialization of non-oral variations of licensed products for treatment of viral diseases other than HBV. NeuroVive retains all rights with respect to development, manufacture and commercialization of licensed products and non-oral variations of licensed products for all indications (other than HBV) for which the Company has not exercised its option.
 

100



In partial consideration for this license, Arbutus Inc. paid NeuroVive a license fee of $1,000,000. As described in note 3 above, Arbutus Inc. became our wholly owned subsidiary by way of a Merger Agreement, which does not trigger any milestone payments. We have conducted significant research and analysis on the NeuroVive Product, OCB-030. Based on this research and analysis, we have decided to discontinue the OCB-030 development program.  Otherwise, the license agreement and ongoing relationship with NeuroVive remains in full effect.

Cytos Biotechnology Ltd (“Cytos”)
 
On December 30, 2014, Arbutus Inc. entered into an exclusive, worldwide, sub-licensable (subject to certain restrictions with respect to licensed viral infections other than hepatitis) license to six different series of compounds. The licensed compounds are Qbeta-derived virus-like particles that encapsulate TLR9, TLR7 or RIG-I agonists and may or may not be conjugated with antigens from the hepatitis virus or other licensed viruses.  The Company has an option to expand this license to include additional viral infections other than influenza and Cytos will retain all rights for influenza, all non-viral infections, and all viral infections (other than hepatitis) for which it has not exercised its option. 
 
In partial consideration for this license, the Company is obligated to pay Cytos up to a total of $67,000,000 for each of the six licensed compound series upon the achievement of specified development and regulatory milestones; for hepatitis and each additional licensed viral infection, up to a total of $110,000,000 upon the achievement of specified sales performance milestones; and tiered royalty payments in the high-single to low-double digits, based upon the proportionate net sales of licensed products in any commercialized combination.

10. Concentrations of business risk
 
Credit risk

Credit risk is defined by the Company as an unexpected loss in cash and earnings if a collaborative partner is unable to pay its obligations in due time. The Company’s main source of credit risk is related to its accounts receivable balance which principally represents temporary financing provided to collaborative partners in the normal course of operations.

The Company does not currently maintain a provision for bad debts as the majority of accounts receivable are from collaborative partners or government agencies and are considered low risk.

The carrying amount of financial assets represents the maximum credit exposure. The maximum exposure to credit risk at December 31, 2015 was the accounts receivable balance of $1,008,000 (2014 - $1,903,000).

All accounts receivable balances were current as at December 31, 2015 and December 31, 2014.
 
Significant collaborators and customers risk

We depend on a small number of collaborators and customers for a significant portion of our revenues (see note 4).
 
Liquidity Risk

Liquidity risk results from the Company’s potential inability to meet its financial liabilities, for example payments to suppliers.  The Company ensures sufficient liquidity through the management of net working capital and cash balances.

The Company’s liquidity risk is primarily attributable to its cash and cash equivalents, and short-term investments. The Company limits exposure to liquidity risk on its liquid assets through maintaining its cash and cash equivalent, and short-term investments with high-credit quality financial institutions. Due to the nature of these investments, the funds are available on demand to provide optimal financial flexibility.

The Company believes that its current sources of liquidity are sufficient to cover its likely applicable short term cash obligations. The Company’s financial obligations include accounts payable and accrued liabilities which generally fall due within 45 days. The net liquidity of the Company is considered to be the cash and cash equivalents and short-term investments less accounts payable and accrued liabilities.

Foreign currency risk

The results of the Company’s operations are subject to foreign currency transaction and translation risk as the Company’s revenues and expenses are denominated in both Canadian and US dollars. The fluctuation of the US dollar in relation to the Canadian dollar will consequently have an impact upon the Company’s reported income or loss and may also affect the value of the Company’s assets, liabilities, and the amount of shareholders’ equity both as recorded in the Company’s financial statements, in the Canadian functional currency, and as reported, for presentation purposes, in the US dollar.

The Company manages its US dollar exchange rate risk by, whenever possible, using cash received from US dollar revenues and financing to pay US dollar expenses. Prior to the financing in October 2013 (note 6(a)), which was denominated in US dollars, the Company’s policy was to convert all but a working capital level of US dollars into Canadian dollars. Given the Company’s increasing level of US dollar expenses, its policy is now to maintain US and Canadian dollar cash and investment and short-term investment balances based on long term forecasts of currency needs thereby creating a natural currency hedge.

The Company has not entered into any agreements or purchased any instruments to hedge possible currency risks. The Company’s exposure to US dollar currency expressed in Canadian dollars was as follows:

13. Subsequent events

(a) Protiva USA Reorganization

Effective January 1, 2016, the Company undertook a corporate reorganization merging Protiva USA into Arbutus Inc., which acquired Protiva USA's assets and assumed Protiva USA's liabilities in exchange for Arbutus Inc. shares. The reorganization did not result in any adverse Canadian and U.S. tax consequences.

(b) Monsanto Option Exercise

On March 4, 2016, Monsanto exercised its option to acquire 100% of the outstanding shares of Protiva Agricultural Development Company Inc. (PADCo), pursuant under its Option Agreement with the Company. Monsanto will pay the Company $1,000,000 in exercise fee, which the Company will record in the statement of operations and comprehensive loss for the period ended March 31, 2016.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

None.

Item 9A. Controls and Procedures
 
Disclosure Controls and Procedures

As of the end of our fiscal year ended December 31, 2015, an evaluation of the effectiveness of our “disclosure controls and procedures” (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) was carried out by our management, with the participation of our Chief Executive Officer (CEO) and Chief Financial Officer (CFO). Based upon that evaluation, the CEO and CFO have concluded that as of the end of that fiscal year, our disclosure controls and procedures are effective to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission (the “Commission”) rules and forms and (ii) accumulated and communicated to the management of the registrant, including the CEO and CFO, to allow timely decisions regarding required disclosure.

It should be noted that while the CEO and CFO believe that our disclosure controls and procedures provide a reasonable level of assurance that they are effective, they do not expect that our disclosure controls and procedures or internal control over financial reporting will prevent all errors and fraud. A control system, no matter how well conceived or operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met.
 

103



Management’s Annual Report on internal control over financial reporting

Management is responsible for establishing and maintaining adequate internal control over our financial reporting, as such term is defined in Rule 13a-15(f) of the Securities Exchange Act of 1934. Our internal control system was designed to provide reasonable assurance that all transactions are accurately recorded, that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our assets are safeguarded.

Management has assessed the effectiveness of our internal control over financial reporting as at December 31, 2015. In making its assessment, management used the Committee of Sponsoring Organizations of the Treadway Commission (COSO) framework in Internal Control – Integrated Framework (2013) to evaluate the effectiveness of our internal control over financial reporting. Based on this assessment, management has concluded that our internal control over financial reporting was effective as of December 31, 2015.

Howard, Ph.D. (the “Executive”) (together the “Parties”), and shall become effective upon Executive’s commencement of employment, which is expected to commence on March 7, 2016 (the “Effective Date”). The Company and Executive agree that in the event the Executive has not commenced employment with the Company as of April 1, 2016 (or such later date as agreed by each of the Company and Executive in writing) then this Agreement shall be void and of no further effect.
RECITALS
WHEREAS, the Company and Executive desire to enter into this Agreement to set forth the terms of Executive’s employment with the Company, as of the Effective Date.
THEREFORE, the Parties agree and intend to be bound as follows:
Section 1.Term. The Company shall employ Executive, and Executive hereby accepts employment with the Company, upon the terms and conditions set forth in this Agreement for the period beginning on the Effective Date and ending as provided in Section 5 hereof.
Section 2.Position and Duties. The Executive will serve as Executive Vice-President and General Counsel of the Company, and will have powers and duties consistent with Executive’s position and as outlined on Exhibit B attached hereto and such other powers and duties consistent with such position as may from time to time be prescribed by the President and Chief Executive Officer of the Company, subject to the power and authority of the Company’s President and Chief Executive Officer to expand or limit such duties, responsibilities, functions and powers. Any increase or reduction in the Executive’s duties, responsibilities, functions or powers hereunder shall not operate to change or modify the compensation or severance, if applicable, to be paid by the Company to the Executive. As the Executive Vice President and General Counsel of the Company, the Executive shall devote her full working time and efforts to the business and affairs of the Company. Notwithstanding the foregoing, the Executive may manage her personal investments or engage charitable or other community activities as long as those services and activities do not interfere with the Executive’s performance of her duties to the Company.
Section 3.Compensation and Related Matters.Base Salary. The Executive’s base salary will be $330,000 per year, less withholdings and payable in accordance with the Company’s normal payroll practices. The Executive’s base salary will be reviewed annually by the Chief Executive Officer of the Company and is subject to increase but not decrease except for an across-the-board salary reduction affecting all or substantially all senior executives of the Company. The base salary in effect at any given time is referred to as “Base Salary” and this Agreement need not be modified to reflect a change in Base Salary. The Base Salary is subject to withholding and payable in a manner that is consistent with the Company’s usual payroll practices for senior executives.
(a)Bonus. The Executive is eligible to be considered for an annual discretionary target bonus of up to 40% of Base Salary, which will be subject to the terms of the bonus plan and the approval of the Company’s Board of Directors (the “Board”), in its sole discretion, on an annual basis.

(b)Expenses. The Executive is entitled to receive prompt reimbursement for all reasonable expenses incurred by her in performing services under this Agreement, in accordance with the policies and procedures then in effect and established by the Company for its senior executives.
(c)Other Benefits. The Executive is entitled to participate in or receive benefits under the Company’s employee benefit plans as they may be adopted and amended from time to time, subject to the terms and conditions of those employee benefit plans.
(d)Equity Compensation. Subject to the discretionary approval of the board of directors of Arbutus Biopharma Corporation, the parent of the Company (the “Parent”) and in accordance with the Company and the Parent’s annual performance and compensation review process in effect from time to time, the Company’s President and CEO will promptly recommend to the Parent’s board of directors that Executive receive an option grant in the amount of 120,000 of shares of the Parent, subject to the terms of the Arbutus Biopharma Corporation Share Incentive Plan, or any other similar equity incentive plan in effect from time to time, the terms of a notice of grant and any such other terms as may be required by the Parent’s board of directors.
(e)Vacations. The Executive is entitled to paid holidays and vacation days each year, in an amount determined in accordance with and subject to the Company’s applicable policies in effect, and as may be amended from time to time. Unless a different number is established by the Board in its sole discretion, the Executive will be entitled to four weeks (20 business days) of vacation per calendar year, which will be pro-rated for any year in which the Executive is only employed with the Company for a portion of the year or for any period in which the Executive is not a full-time employee. Executive may carry over unused and accrued vacation days from year to year, but total vacation accrual will be capped at 34 days. Any accrued but unused vacation days will be paid upon termination.
(f)Paid Sick Time. The Executive will be awarded paid sick days in accordance with Company policy.

Section 5.Termination. Executive will continue to be employed by the Company as Executive Vice-President and General Counsel until termination pursuant to this Section 5 of this Agreement. Executive’s employment by the Company may be terminated without any breach of this Agreement under the following circumstances:
(a)Death. The Executive’s employment hereunder terminates upon her death.
(b)Disability. The Company may terminate the Executive’s employment if she is disabled (as determined by the Chief Executive Officer) in a manner that renders the Executive unable to perform the essential functions of her then existing position or positions under this Agreement with or without reasonable accommodation for a period of six months or more. Nothing in this Section 1(b) is to be construed to waive the Executive’s rights, if any, under existing law including, without limitation, the Family and Medical Leave Act of 1993, 29 U.S.C. §2601 et seq., and the Americans with Disabilities Act, 42 U.S.C. §12101 et seq., and the California Fair Employment and Housing Act.
(c)Termination by Company for Cause. For purposes of this Agreement, “For Cause” shall mean: (i) Employee commits a felony , or any crime involving dishonesty, breach of trust, or physical harm to any person; (ii) Employee willfully engages in conduct that is in bad faith and materially injurious to the Company, including but not limited to, misappropriation of trade secrets, fraud or embezzlement; (iii) Employee commits a material breach of this Agreement; (iv) Employee willfully refuses to implement or follow a lawful policy or directive of the Company; or (v) Employee engages in misfeasance or malfeasance demonstrated by a pattern of failure to perform job duties diligently and professionally. The Company may terminate Employee’s employment For Cause at any time, without any advance notice. The Company shall pay Employee all compensation to which Employee is entitled up through the date of termination, subject to any other rights or remedies of the Company under law; and thereafter all obligations of the Company under this Agreement shall cease.
(d)Termination by the Company Without Cause or by the Executive for Good Reason. The Company may terminate the Executive’s employment under this Agreement at any time without Cause and for any reason, and the Executive may terminate her employment with Good Reason. For purposes of this Agreement, “Good Reason” means the occurrence of any of the following events without the Executive's prior written consent: (i) the failure of the Executive to be appointed to the position set forth in Section 2, if not promptly cured after written notice; or (ii) a reduction by the Company of the Executive's Base Salary or Target Bonus percentage, except for an across-the-board salary reduction affecting all or substantially all senior executives of the Company. For purposes of this Agreement, termination for Good Reason requires Executive to comply with the “Good Reason Process,” which means that (i) the Executive reasonably determines in good faith that a Good Reason condition has occurred; (ii) the Executive notifies the Company in writing of the first occurrence of the Good Reason condition within 30 days of the first occurrence of such condition (the “Good Reason Notice”); (iii) the Executive cooperates in good faith with the Company’s efforts, for a period of not less than 30 days following that notice (the “Cure Period”) to remedy the condition; (iv) notwithstanding the Company’s efforts, the Good Reason condition continues to exist; and (v) the Executive gives a Notice of Termination effective within 10 days after the end of the Cure Period. If the Company cures the Good Reason condition during the Cure Period, Good Reason is deemed not to have occurred. Notwithstanding the foregoing, upon the Company’s receipt of the Good Reason Notice, the Company may, in its sole discretion, elect to immediately accept a termination by the Executive for Good Reason, waive the requirement for a Cure Period and such termination will not be deemed a termination by the Company for purposes of this Agreement.

 



Any termination by the Company of the Executive’s employment under this Agreement that does not constitute a termination for Cause under Section 5(c) and does not result from the death or disability of the Executive under Section 5(a) or (b) is a termination without Cause.
(e)Termination by the Executive. Executive may terminate employment with the Company without Good Reason at any time for any reason or no reason at all, upon thirty (30) days’ advance written notice. The Company shall have the option, in its sole discretion, to make Executive’s termination effective or to direct the Executive to perform no work and/or remain off premises at any time prior to the end of such notice period as long as the Company pays Executive all compensation to which Executive is entitled up through the last day of the 30 day notice period.
(f)Notice of Termination. Except for termination as specified in Section 5(a) any termination of the Executive’s employment by the Company or any termination of her employment by the Executive must be communicated by written Notice of Termination to the other party. For purposes of this Agreement, a “Notice of Termination” means a notice that indicates the specific termination provision in this Agreement that the termination is based upon.
(g)Date of Termination. “Date of Termination” means: (i) if the Executive’s employment is terminated by her death, the date of her death; (ii) if the Executive’s employment is terminated on account of disability under Section 5(b) or by the Company for Cause under Section 5(c), or by the Company without Cause under Section 5(d) on the date the Notice of Termination is given; (iii) if the Executive terminates her employment under Section 5(e) Good Reason, on the date specified by the Executive in the notice (which shall be at least 30 days after the date of the Notice of Termination); and (iv) if the Executive terminates her employment under Section 5(d) with Good Reason, the date of the effectiveness of the Notice of Termination, which shall be during the ten day period following the Cure Period, or, if the Company elects to immediately accept the termination by the Executive for Good Reason, on such date of the Company’s acceptance. Notwithstanding the foregoing, if the Executive gives a Good Reason Notice or a Notice of Termination to the Company that takes effect at a future date, the Company may unilaterally accelerate the Date of Termination and that acceleration will not be deemed a termination by the Company for purposes of this Agreement.
Section 6.Compensation Upon Termination.
(a)Termination Generally. If the Executive’s employment with the Company is terminated for any reason, the Company shall pay or provide to the Executive (or to her authorized representative or estate), (i) unpaid expense reimbursements; (ii) accrued but unused vacation to the extent payment is required by law or Company policy; (iii) any vested benefits the Executive may have under any employee benefit plan of the Company; (iv) any earned but unpaid base salary and (v) any earned but unpaid annual bonus for the prior fiscal year (collectively the “Accrued Benefit”) on or before the time required by law, but in no event more than 30 days after the Executive’s Date of Termination. The Executive shall not be entitled to any other salary, compensation, bonus (or pro rata share thereof) or benefits from the Company thereafter, except as otherwise specifically provided hereunder, under the Company’s employee benefit plans or as expressly required by applicable law.
(b)Termination by the Company Without Cause or by the Executive for Good Reason. If the Executive’s employment is terminated by the Company without Cause or by the Executive for Good Reason, then the Company shall pay the Executive her Accrued Benefit as of the Date of Termination. In addition, subject to the Executive providing the Company with a fully effective general release of claims in a form and manner satisfactory to the Company that includes but is not limited to the

 



terms set forth in the attached Exhibit A (the “Release”) within the 60-day period following the Date of Termination, the Company shall pay the Executive (i) severance pay in a lump sum in cash in an amount equal to one and one-half times the Executive’s Base Salary (“Severance Amount”), less withholding, payable within 60 days after the Date of Termination, but if that 60-day period extends over two calendar years, the Company shall make the payment in the second calendar year, (ii) a bonus payment equal to the Target Bonus pro-rated for the portion of the year the Executive was employed by the Company prior to the termination, and (iii) provided that the Executive timely elects COBRA coverage, reimburse the Executive for the COBRA premiums paid by the Executive, if any, for the continuation of coverage under the Executive’s then-existing group company health plan that the Executive and her dependents are eligible to receive for the earlier of (x) a period of up to 24 months from the date of the Executive’s termination of employment, or (y) until the Executive becomes eligible to receive health insurance benefits under any other employer’s group health plan.
Section 7.Change of Control Provisions. The provisions of this Section 7 set forth the Executive’s rights and obligations upon the occurrence of a Change of Control of the Company. These provisions are intended to assure and encourage in advance the Executive’s continued attention and dedication to her assigned duties and her objectivity during the pendency and after the occurrence of any Change of Control. The provisions of this Section 7 apply in addition to, and/or modify, the provisions of Section 6 regarding severance pay and benefits upon a termination of employment, if applicable, if the termination of employment occurs within 12 months after the occurrence of a Change of Control. These provisions are subject to the Executive providing (and not revoking) the Company with a fully effective Release. These provisions terminate and are of no further force or effect beginning 12 months after the occurrence of such a Change of Control.
(a)Severance following Change of Control. If within 12 months following a Change of Control (i) the Company terminates the Executive’s employment with the Company other than for Cause, or (ii) the Executive resigns from her employment with the Company for Good Reason, within the 60-day period following the Date of Termination, then, in lieu of paying the Executive the Severance Amount and in addition to paying the Accrued Benefit, Company shall: (i) pay the Executive severance pay in a lump sum in cash (less applicable withholdings) in an amount equal to two times the Executive’s Base Salary (“Change in Control Severance Amount”), payable within 60 days after the Date of Termination, but if that 60-day period extends over two calendar years, the Company shall make the payment in the second calendar year; (ii) pay the Executive a bonus payment equal to the Target Bonus pro-rated for that portion of the year that Executive is employed (iii) provided that the Executive timely elects COBRA coverage, reimburse the Executive for the COBRA premiums paid by the Executive, if any, for the continuation of coverage under the Executive’s then-existing group company health plan that the Executive and her dependents are eligible to receive for the earlier of (x) a period of up to 24 months from the date of the Executive’s termination of employment, or (y) until the Executive becomes eligible to receive health insurance benefits under any other employer’s group health plan; and (iv) cause all stock options and other stock-based awards granted after the Effective Date and held by the Executive to immediately accelerate, vest, and become fully exercisable or nonforfeitable.
(b)Additional Limitation.
(i)Anything in this Agreement to the contrary notwithstanding, if the amount of any compensation, payment, acceleration, benefit, or distribution by the Company to or for the benefit of the Executive, whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise, calculated in a manner consistent with Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”) and the applicable regulations thereunder (the “Severance

 



Payments”), would be subject to the excise tax imposed by Section 4999 of the Code, then the Severance Payments will be reduced (but not below zero) to the extent necessary so that the sum of all Severance Payments does not exceed the Threshold Amount (defined below), but if the after-tax amount the Executive would receive if there were no reduction pursuant to this section (including any federal, state, and local taxes) exceeds the after-tax amount the Executive would receive if the Severance Payments were reduced below the Threshold Amount, the Severance Payments will no longer be so reduced. If Severance Payments are required to be reduced, the Severance Payments will be reduced in the following order: (1) cash payments not subject to Section 409A of the Code; (2) cash payments subject to Section 409A of the Code; (3) equity-based payments and acceleration; and (4) non-cash forms of benefits.
(ii)For the purposes of this Section 7(b), “Threshold Amount” means three times the Executive’s “base amount” within the meaning of Section 280G(b)(3) of the Code and the regulations promulgated thereunder less one dollar ($1.00).
(iii)The determinations under this Section 7(b) will be made by a nationally recognized accounting firm selected by the Company (the “Accounting Firm”), which must provide detailed supporting calculations both to the Company and the Executive within 15 business days of the Date of Termination, if applicable, or at such earlier time as is reasonably requested by the Company or the Executive.
(c)Change of Control Definition. For purposes of this Section 7, “Change of Control” means the consummation of any of the following:
(i)    the sale of all or substantially all of the assets of the Company or the Parent to an unrelated person or entity;
(ii)    a merger, reorganization, or consolidation involving the Company or the Parent in which the shares of voting stock outstanding immediately prior to the transaction represent or are converted into or exchanged for securities of the surviving or resulting entity that, immediately upon completion of the transaction, represent less than 50% of the outstanding voting power of the surviving or resulting entity;
(iii)    the acquisition of all or a majority of the outstanding voting stock of the Company or the Parent in a single transaction or a series of related transactions by a person or group of persons; or
(iv)    any other acquisition of the business of the Company or the Parent, as determined by the Board;
but the Company’s initial public offering, any subsequent public offering, or another capital raising event, or a merger effected solely to change the Company’s domicile does not constitute a Change of Control.
Section 8.Section 409A Compliance. The following rules shall apply, to the extent necessary, with respect to distribution of the payments and benefits, if any, to be provided to the Executive under this Agreement. Subject to the provisions in this Section, the severance payments pursuant to this Agreement shall begin only upon the date of the Executive's “separation from service” (determined as set forth below) which occurs on or after the date of the Executive's termination of employment.

 



(a)This Agreement is intended to comply with Code Section 409A (to the extent applicable) and the parties hereto agree to interpret, apply and administer this Agreement in the least restrictive manner necessary to comply therewith and without resulting in any increase in the amounts owed hereunder by the Company.
(b)It is intended that each installment of the severance payments and benefits provided under this Agreement shall be treated as a separate “payment” for purposes of Section 409 A of the Internal Revenue Code of 1986, as amended, and the guidance issued thereunder (“Section 409A”). Neither the Executive nor the Company shall have the right to accelerate or defer the delivery of any such payments or benefits except to the extent specifically permitted or required by Section 409A.
(c)If, as of the date of the Executive's “separation from service” from the Company, the Executive is not a “specified employee” (within the meaning of Section 409 A), then each installment of the severance payments and benefits shall be made on the dates and terms set forth in this Agreement.
(d)If, as of the date of the Executive's “separation from service” from the Company, the Executive is a “specified employee” (within the meaning of Section 409A), then:
(i)Each installment of the severance payments and benefits due under this Agreement that, in accordance with the dates and terms set forth herein, will in all circumstances, regardless of when the separation from service occurs, be paid within the short-term deferral period (as defined in Section 409A) shall be treated as a short-term deferral within the meaning of Treasury Regulation Section 1.409A-l(b)(4) to the maximum extent permissible under Section 409A; and
(ii)Each installment of the severance payments and benefits due under this Agreement that is not described in Section 7(d)(i) above and that would, absent this subsection, be paid within the six-month period following the Executive's “separation from service” from the Company shall not be paid until the date that is six months and one day after such separation from service (or, if earlier, the Executive's death), with any such installments that are required to be delayed being accumulated during the six-month period and paid in a lump sum on the date that is six months and one day following the Executive's separation from service and any subsequent installments, if any, being paid in accordance with the dates and terms set forth herein; provided, however, that the preceding provisions of this sentence shall not apply to any installment of severance payments and benefits if and to the maximum extent that such installment is deemed to be paid under a separation pay plan that does not provide for a deferral of compensation by reason of the application of Treasury Regulation 1.409A-1 (b)(9)(iii) (relating to separation pay upon an involuntary separation from service). Any installments that qualify for the exception under Treasury Regulation Section 1.409A-l(b)(9)(iii) must be paid no later than the last day of the second taxable year following the taxable year in which the separation from service occurs.
(e)The determination of whether and when the Executive's separation from service from the Company has occurred shall be made in a manner consistent with, and based on the presumptions set forth in, Treasury Regulation Section 1.409A-l(h). Solely for purposes of this Section, “Company” shall include all persons with whom the Company would be considered a single employer as determined under Treasury Regulation Section 1.409A-l(h)(3).
(f)All reimbursements and in-kind benefits provided under this Agreement shall be made or provided in accordance with the requirements of Section 409A to the extent that such reimbursements or in-kind benefits are subject to Section 409A, including, where applicable, the requirements that (i) any reimbursement is for expenses incurred during the Executive's lifetime (or during a shorter period of time specified in this Agreement), (ii) the amount of expenses eligible for

 



reimbursement during a calendar year may not affect the expenses eligible for reimbursement in any other calendar year, (iii) the reimbursement of an eligible expense will be made on or before the last day of the calendar year following the year in which the expense is incurred and (iv) the right to reimbursement is not subject to set off or liquidation or exchange for any other benefit.
(g)Notwithstanding anything herein to the contrary, the Company shall have no liability to the Executive or to any other person if the payments and benefits provided in this Agreement that are intended to be exempt from or compliant with Section 409A are not so exempt or compliant.
Section 9.Confidential Information. Employee agrees to enter into the Company’s standard Employee Confidentiality and Proprietary Rights Agreement (the “Confidential Information Agreement”). Employee’s receipt of any benefits in connection with or following Employee’s termination will be subject to Employee continuing to comply with the terms of Confidential Information Agreement.
Section 10.Cooperation; Other Documents; Non-Disclosure.
(a)Litigation and Regulatory Cooperation. During and after the Executive’s employment, the Executive shall reasonably cooperate with the Company in the defense or prosecution of any claims or actions now in existence or which may be brought in the future against or on behalf of the Company which relate to events or occurrences that took place while the Executive was employed by the Company. The Executive’s reasonable cooperation in connection with such claims or actions includes, but is not limited to, being available to meet with counsel to prepare for discovery or trial and to act as a witness on behalf of the Company at mutually convenient times. During and after the Executive’s employment, the Executive also shall reasonably cooperate with the Company in connection with any investigation or review of any federal, state, or local regulatory authority as any such investigation or review relates to events or occurrences that took place while the Executive was employed by the Company. The Company shall compensate Executive for her time spent, and reimburse the Executive for any reasonable out-of-pocket expenses incurred, in connection with the Executive’s performance of obligations pursuant to this Section 10.
(b)Non-Disclosure. The Executive shall use her reasonable efforts to maintain the confidentiality of the terms of this Agreement to the extent permitted by law, but the Executive may disclose the terms to her immediate family members and to her legal, tax, and other advisors.
Section 11.Arbitration of Disputes.
(c)Scope of Arbitration Requirement. The Executive hereby waives her right to a trial before a judge or jury and agrees to arbitrate before a neutral arbitrator skilled in hearing similar disputes any and all claims or disputes arising out of this Agreement and any and all claims arising from or relating to her employment, including but not limited to claims against any current or former employee, director, or agent of the Company, claims of wrongful termination, retaliation, discrimination, harassment, breach of contract (including but not limited to disputes pertaining to the formation, validity, interpretation or effect of this Agreement), breach of the covenant of good faith and fair dealing, defamation, invasion of privacy, fraud, misrepresentation, constructive discharge or failure to provide a leave of absence, or claims regarding commissions, stock options or bonuses, infliction of emotional distress, or unfair business practices (each an “Arbitrable Dispute”). Arbitration is the exclusive remedy for any Arbitrable Dispute, instead of any court or administrative action, unless the waiver of a certain court or administrative action is prohibited by law.

 



(d)Procedure. Any arbitration will be administered by the American Arbitration Association (“AAA”) and the neutral arbitrator will be selected in a manner consistent with AAA’s National Rules For The Resolution of Employment Disputes (“Applicable Arbitration Rules”). Any arbitration under this Agreement must be conducted in the State of California, and the arbitrator must administer and conduct the arbitration in accordance with the Applicable Arbitration Rules, except that (i) the arbitrator must allow for the discovery authorized by the California Rules of Civil Procedure or the discovery that the arbitrator decides is necessary for the Parties to vindicate their respective claims or defenses, and (ii) presentation of evidence will be governed by the California Rules of Evidence. Within a reasonable time after the conclusion the arbitration proceedings, the arbitrator shall issue a written decision and must include the findings of fact and law that support that decision. The arbitrator has the power to award any remedies available under applicable law, and the arbitrator’s decision is final and binding on both Parties, except to the extent applicable law allows for judicial review of arbitration awards.
(e)Costs. The Company shall bear all the costs of arbitration, except that the Executive shall pay the first $125.00 of any filing fees associated with any arbitration the Executive initiates. Both Parties are responsible for their own attorneys’ fees, and the arbitrator may not award attorneys’ fees unless a statute or contract at issue specifically authorizes such an award.
(f)Applicability. This Section 11, does not apply to (i) workers’ compensation or unemployment insurance claims or (ii) claims concerning ownership, validity, infringement, misappropriation, disclosure, misuse, or enforceability of any confidential information, patent right, copyright, mask work, trademark, or any other trade secret or intellectual property held or sought by either the Executive or the Company.
(g)Remedy. Should any party institute any legal action or administrative proceeding against the other with respect to any claim waived by this Agreement or pursue any Arbitrable Dispute by any method other than as set forth above, except to enforce the arbitration provisions and as expressly provided for in this Section 11, the responding party is entitled to recover from the initiating party all damages, costs, expenses, and attorneys’ fees incurred as a result of that action.
Section 12.Consent to Jurisdiction. To the extent that any court action is initiated to enforce Section 11 of this Agreement, the Parties hereby consent to the jurisdiction of any state court in the State of California and any U.S. District Court sitting in the State of California. Accordingly, with respect to any such court action, the Executive (a) submits to the personal jurisdiction of such courts; (b) consents to service of process; and (c) waives any other requirement (whether imposed by statute, rule of court, or otherwise) with respect to personal jurisdiction or service of process.  
Section 13.Integration. This Agreement and the Confidential Information Agreement executed concurrently herewith, constitute the entire agreement between the Parties with respect to the subject matter hereof and supersedes all prior agreements between the Parties concerning such subject matter, but any indemnification agreement between the Parties, and all plans and agreements related to stock options and other stock-based awards held by the Executive remain in full force and effect except to the extent specifically modified by this Agreement. Without limiting the foregoing, the parties agree that any employment agreement, other than this Agreement, existing between the Parties as of the date hereof is hereby terminated and shall be of no force of effect.
Section 14.Withholding. All payments made by the Company to the Executive under this Agreement will be net of any tax or other amounts required to be withheld by the Company under

 



applicable law. Nothing in this Agreement is to be construed to obligate the Company to design or implement any compensation arrangement in a way that minimizes tax consequences for the Executive.
Section 15.Successor to the Executive. This Agreement inures to the benefit of and is enforceable by the Executive’s personal representatives, executors, administrators, heirs, distributees, devisees, and legatees. If the Executive dies after her termination of employment but prior to the completion by the Company of all payments due her under this Agreement, the Company shall continue the payments to the Executive’s beneficiary designated in writing to the Company prior to her death (or to her estate, if the Executive fails to make such a designation).
Section 16.Enforceability. If any portion or provision of this Agreement is declared illegal or unenforceable by a court of competent jurisdiction, then the remainder of this Agreement, or the application of that portion or provision in circumstances other than those as to which it is so declared illegal or unenforceable, will not be affected by that declaration, and each portion and provision of this Agreement will continue to be valid and enforceable to the fullest extent permitted by law.
Section 17.Survival. The provisions of this Agreement survive the termination of this Agreement and/or the termination of the Executive’s employment to the extent necessary to effectuate the intent of the Parties as expressed in this Agreement.
Section 18.Waiver. No waiver of any provision of this Agreement is effective unless made in writing and signed by the waiving party, and, in the case of the Company only after the waiver has been specifically approved by the Board. The failure of either party to require the performance of any term or obligation of this Agreement, or the waiver by either party of any breach of this Agreement, will not prevent any subsequent enforcement of such term or obligation or be deemed a waiver of any subsequent breach.
Section 19.Notices. Any notices, requests, demands, and other communications provided for by this Agreement are sufficient if in writing and delivered in person or sent by a nationally recognized overnight courier service or by registered or certified mail, postage prepaid, return receipt requested, to the Executive at the last address the Executive has filed in writing with the Company or, in the case of the Company, at its main offices, attention to the Corporate Secretary.
Section 20.Amendment. This Agreement may be amended or modified only by a written instrument signed by the Executive and by a duly authorized representative of the Company.
Section 21.Governing Law. This Agreement is to be construed under and be governed in all respects by the laws of the State of California without giving effect to the conflict of laws principles of that state.  
Section 22.Counterparts. This Agreement may be executed in any number of counterparts, and by each party on separate counterparts, each of which counterparts, when so executed and delivered is to be taken to be an original; but those counterparts together constitute one and the same document. PDF, facsimile, scanned, and electronic signatures have the same legal effect as original ink signatures.
Section 23.Successor to Company. The Company shall require any successor (whether direct or indirect, by purchase, merger, consolidation, or otherwise) to all or substantially all of the business or assets of the Company expressly to assume and agree to perform this Agreement to the same extent that the Company would be required to perform it if no succession had taken place. Failure of the Company to

 



obtain an assumption of this Agreement at or prior to the effectiveness of any succession is a material breach of this Agreement.
Section 24.Voluntary Nature of Agreement. The Executive acknowledges and agrees that she is executing this Agreement voluntarily and without any duress or undue influence by the Company or anyone else. The Executive further acknowledges and agrees that she has carefully read this Agreement and that she has asked any questions needed for her to fully understand the terms, consequences, and binding effect of this Agreement. The Executive agrees that she has been provided an opportunity to seek the advice of an attorney of her choice before signing this Agreement.
The Parties are executing this Executive Agreement as of the date set forth in the introductory paragraph.

EXHIBIT A
FORM OF GENERAL RELEASE

This General Release and Waiver (“Release”) is made and entered into as of ________________________ (the “Release Date”), by and between Arbutus Biopharma, Inc. (the “Company”), and Elizabeth A. Howard, Ph.D. (the “Executive”). The Company and/or Executive may hereinafter be referred to individually as a "Party" or collectively as the "Parties."

In consideration of the mutual covenants hereinafter set forth, the Parties hereby agree as follows:

1.    Separation. Executive’s employment with Employer ended effective ______________________.

2.    Payment and Benefits. In consideration of the promises made in this Release, Employer has agreed to pay Executive the benefits described in the applicable provisions of Sections 5 and 6 (and, in the event of a Change in Control, Section 7) of that certain Executive Employment Agreement made and entered into between the Parties (the “Employment Agreement”). Executive understands and acknowledges that the benefits described in this Section 2 constitute benefits in excess of those to which Executive would be entitled without entering into this Release. Executive acknowledges that such benefits are being provided by Employer as consideration for Executive entering into this Release, including the release of claims and waiver of rights provided in Section 3 of this Release.

3.    Release of Claims and Waiver of Rights.
(a)    Executive, on Executive’s own behalf and that of Executive’s spouse, heirs, executors or administrators, assigns, insurers, attorneys and other persons or entities acting or purporting to act on Executive’s behalf (the “Executive’s Parties”), hereby irrevocably and unconditionally release, acquit and forever discharge Employer, its affiliates, subsidiaries, directors, officers, employees, shareholders, partners, agents, representatives, predecessors, successors, assigns, insurers, attorneys, benefit plans sponsored by Employer and said plans’ fiduciaries, agents and trustees (the “Released Parties”), from any and all actions, cause of action, suits, claims, obligations, liabilities, debts, demands, contentions, damages, judgments, levies and executions of any kind, whether in law or in equity, known or unknown, which the Executive’s Parties have, have had, or may in the future claim to have against the Released Parties by reason of, arising out of, related to, or resulting from Executive’s employment with Employer or the termination thereof. This release specifically includes without limitation any claims arising in tort or contract, any claim based on wrongful discharge, any claim based on breach of contract, any claim arising under federal, state or local law prohibiting race, sex, age, religion, national origin, handicap, disability or other forms of discrimination, any claim arising under federal, state or local law concerning employment practices, and any claim relating to compensation or benefits. This specifically includes, without limitation, any claim which the Executive has or has had under
Title VII of the Civil Rights Act of 1964; 42 U.S.C. §§ 1981-1988; the Americans with Disabilities Act; , the Age Discrimination in Employment Act (and the Older Workers Benefit Protection Act), the Fair Labor Standards Act; the Family and Medical Leave Act; the Workers Adjustment and Retraining Notification Act, as amended; the Occupational Safety and Health Act, as amended, the Sarbanes-Oxley Act of 2002, the Dodd-Frank Wall Street Reform and Consumer Protection Act, the California Family Rights Act (Cal. Govt. Code § 12945.2 et seq.), the California Fair Employment and Housing Act (Cal. Govt.





Code § 12900 et seq.), statutory provision regarding retaliation/discrimination for filing a workers’ compensation claim under Cal. Labor Code § 132a, and/or any other claims of whatever nature arising in connection with Executive’s employment with the Company or her separation from such employment, and any and all other claims arising under federal, state or local law. Executive acknowledges she received any and all leaves of absence to which she may have been entitled during employment, and that she suffers from no workplace injuries arising from her employment at the Company, and does not intend to file any claim for workers’ compensation benefits. It is understood and agreed that the waiver of benefits and claims contained in this section does not include: (i) a waiver of the right to payment of any vested, nonforfeitable benefits to which the Executive or a beneficiary of the Executive may be entitled under the terms and provisions of any employee benefit plan of Employer which have accrued as of the separation date; (ii) a waiver of the right to benefits and payment of consideration to which Executive may be entitled under the Employment Agreement or any of the agreements contemplated thereby (including indemnification agreements and the stock option agreements); and (iii) a waiver of any rights to indemnification under the Certificate of Incorporation or Bylaws of the Employer or an subsidiary of Employer or under applicable law and regulation. Executive acknowledges that she is only entitled to the severance benefits and compensation set forth in the Employment Agreement, and that all other claims for any other benefits or compensation are hereby waived, except those expressly stated in the preceding sentence.
Nothing in this Release shall be deemed to require the waiver or release of any claim that may not be released or waived under applicable federal or state law. To the extent required by law, nothing contained in this Agreement shall be construed to prohibit Executive from filing a charge or complaint, including a challenge to the validity of the waiver provision of this Agreement, with the U.S. Equal Employment Opportunity Commission, or participating in any investigation conducted by the U.S. Equal Employment Opportunity Commission; provided, however, that Executive has waived her right to any monetary damages or other individual legal or equitable relief awarded as a result of any such proceeding. Nothing contained in this Agreement shall bar a claim by either party to enforce the terms of this Agreement.
(b)    Executive hereby acknowledges that she understands that under this Release she is releasing any known or unknown claims she may have arising out of, related to, or resulting from Executive’s employment with Employer or the termination thereof (the "Released Claims"). She therefore acknowledges that she has read and understands Section 1542 of the California Civil Code, which reads as follows:
“A general release does not extend to claims which the creditor does not know or suspect to exist in his or her favor at the time of executing the release, which if known by him or her must have materially affected his or her settlement with the debtor.”
Executive expressly waives and relinquishes all rights and benefits under that section and any law of any jurisdiction of similar effect with respect to the Released Claims.
4.    Acknowledgment of Waiver of Claims under ADEA. Executive acknowledges that Executive is waiving and releasing any rights Executive may have under the Age Discrimination in Employment Act of 1967 (“ADEA”) and that this waiver and release is knowing and voluntary. Executive acknowledges that the consideration given for this Release is in addition to anything of value to which Executive already is entitled. Executive further acknowledges that Executive has been advised by this writing that:
(a)    the release and waiver granted herein does not relate to claims under the ADEA which may arise after this Release is executed;
(b)    Executive should consult with an attorney prior to executing this Release;





(c)    Executive has at least twenty-one (21) days within which to consider this Release as it relates to claims under the ADEA, although Executive may accept the terms of this Release at any time within those 21 days and earlier execute this Release;
(d)    Executive has seven (7) days following the execution of this Release to revoke this Release as it relates to claims under the ADEA; and
(e)    This Release will not be effective as it relates to claims under the ADEA until the revocation period has expired, which will be the eighth (8th) day after this Release is executed by both Parties, and the severance payments described in the Employment Agreement will not be paid until this Release has become effective and all statutory revocation periods have expired.

5.    Non-Disparagement. The parties agree to treat each other respectfully and professionally and not disparage the other party, and the other party’s officers, directors, employees, shareholders and agents, in any manner likely to be harmful to them or their business, business reputation or personal reputation; provided that both the Executive and Employer will respond accurately and fully to any question, inquiry or request for information when required by the legal process.

6.    No Admissions. Employer denies that it or any of its employees or agents has taken any improper action against Executive. Nothing contained herein shall be deemed as an admission by Employer of any liability of any kind to Executive, all such liability being expressly denied. Further, this Release shall not be admissible in any proceeding as evidence of improper action by Employer or any of its employees or agents.

7.    Non-Waiver. Employer’s waiver of a breach of this Release by Executive shall not be construed or operate as a waiver of any subsequent breach by Executive of the same or of any other provision of this Release.

8.    Restrictive Covenants. Executive understands that the covenants in Section 4 of the Employment Agreement survive the termination of her employment with Employer.

9.    Amendment, Waiver. No amendment or variation of the terms of this Release shall be valid unless made in writing and signed by Executive and Employer. A waiver of any term or condition of this Agreement shall not be construed as a general waiver by Employer. Failure of either Employer or Executive to enforce any provision or provisions of this Agreement shall not waive any enforcement of any continuing breach of the same provision or provisions or any breach of any provision or provisions of this Agreement.

From and after the Closing, Monsanto Canada shall have the right, but not the obligation, exercisable by delivery of written notice to Protiva by Monsanto Canada, to set off against and reduce the amount of any Commercial Milestone Payment by an amount equal to [***] of any and all royalties, license fees and other consideration payable under licenses obtained from Third Parties deemed reasonably necessary or appropriate by Monsanto Canada in its discretion to avoid any claims that any Compound, Formulation or Product infringes the intellectual property rights of such Third Parties directed to lipid nano particles or the use or manufacture of lipid nano particles; provided, however, that in no event shall such set off reduce the Commercial Milestone Payment by more than one-third of the amount of such payment (e.g., if a Commercial Milestone Payment is made pursuant to part (i) of Section 3.1(a) of the PadCo-Protiva License and Services Agreement and there has been no Change of Control of Protiva or Arbutus, then in no event shall Protiva receive less than [***] as such Commercial Milestone Payment, or if such Commercial Milestone Payment is made and there has been a Change of Control of Protiva or Arbutus, then in no event shall Protiva receive less than [***]).

If Monsanto Canada is required by any Governmental Authority to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to Protiva or any assignee such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code, or any applicable provision of state, local or foreign Tax Law, Monsanto Canada shall gross up the payments owed to Protiva so that Protiva receives net of withholding taxes the amount Protiva would otherwise have received but for such withholding. The parties hereto agree to make commercially reasonable efforts to inform one another of potential exceptions to withholding obligations. To the extent that Protiva, its assignees, or successors are able to obtain a refund of such Tax withheld by Monsanto Canada, Protiva, its assignees, or successors agree to make a good-faith effort to obtain such refund and remit such refund to Monsanto, its assignees, or successors within thirty days of receipt of such refund. The parties will use their commercially reasonable efforts to mitigate any withholding Tax on any payments hereunder, including providing any appropriate certification or other documentation.
(h)    Change of Control of Protiva or Tekmira. In the event of a Change of Control of Protiva or Tekmira with a Principal Competitor, the Commercial Milestone Payment under the PadCo-Protiva License and Services Agreement (if and when either is paid or payable under the terms of such agreement) shall be reduced by [***]. Such amounts may be further reduced in accordance with Section 3(f) above.

ARTICLE II –    LICENSE GRANTS AND RELATED RIGHTS
2.1    License Grants to Licensee    .

11




this Agreement, and such Patent or Know-How shall thereafter be included in Protiva Intellectual Property for all purposes of this Agreement. For the avoidance of doubt, (a) Protiva has not granted to Licensee any right or license to the Protiva Intellectual Property outside of the Agricultural Field, (b) Licensee shall have the right to develop and manufacture Compounds and Formulations in connection with the exercise of its rights to Discover, Develop, Commercialize and Manufacture Products, and to discover, develop, commercialize, and manufacture other products and processes that use or employ Protiva Intellectual Property, in the Agricultural Field, and (c) all UBC IP is expressly excluded from this Agreement, and Licensee is not granted any rights in or to any UBC IP, other than as may be granted pursuant to the second sentence of this Section 2.1.

Licensee shall assume full responsibility for the performance of all obligations and observance of all terms herein under the licenses granted to it. If Licensee becomes aware of a material breach of any sublicense by a Sublicensee, Licensee shall promptly notify Protiva of the particulars of same and take all reasonable efforts to enforce the terms of such sublicense. Any agreement between Licensee and the Sublicensee shall provide that such Sublicensee may only use the Confidential Information of Protiva in accordance with terms of this Agreement applicable to Licensee’s use of such Confidential Information and subject to provisions at least as stringent as those set forth in Article VI, and Protiva shall be an express third party beneficiary of such agreement, including provisions related to use and disclosure of Confidential Information. Subject to the foregoing provisions of this Section 2.2(a), Sublicensees shall have the right to further sublicense Protiva Intellectual Property in the Agricultural Field to Third Parties.
(b)    Unless otherwise provided in this Agreement, Licensee shall notify Protiva within thirty (30) days after execution of a sublicense entered into hereunder and provide a copy of the fully executed sublicense agreement to Protiva within the same time, which shall be treated as Confidential Information of Licensee under Article VI.

(a)    Each Party shall promptly report in writing to the other Party during the Term known or suspected commercially relevant infringement by a Third Party of any of the Protiva Background Patents in any field and any known or suspected infringement by a Third Party of any of the Protiva Background Patents in the Agricultural Field of which such Party becomes aware and shall provide the other Party with all evidence supporting or relating to such infringement in its possession.
(b)    Protiva shall have the sole and exclusive right to initiate an infringement or other appropriate suit with respect to infringements or suspected infringements of any of the Protiva Background Patents, or to take such other actions as Protiva, in its sole discretion, deems appropriate with respect to such infringements or suspected infringements (“Background Patent Infringement Action”).

Licensee shall use reasonable best efforts to notify Protiva prior to initiating any Project Patent Infringement Action and shall continue to inform Protiva of the status of any Project Patent Infringement Action initiated by Licensee, including by responding to Protiva’s reasonable requests for status reports, providing drafts of substantive filings of Licensee prior to the due date for such filings, and providing copies of substantive filings of any other party to any such Project Patent Infringement Action promptly after receiving such filings. If any monetary judgment or settlement is recovered in connection with any Project Patent Infringement Action initiated by Licensee or Protiva in accordance with this Section 5.4(b), then, after Licensee or Protiva, as applicable, recoups actual costs and reasonable expenses associated with such Project Patent Infringement Action, (i) then if the monetary judgment or settlement is primarily attributable to infringement in the Agricultural Field, Licensee shall be entitled to receive from the remainder an amount equal to all direct damages attributable to infringement in the Agricultural Field awarded in such judgment or payable under such settlement; Protiva shall then be entitled to receive from the remainder after such payment to Licensee, if any, an amount equal to all direct damages attributable to infringement outside of the Agricultural Field awarded in such judgment or payable under such settlement; and the balance, if any, remaining after such payments to Licensee and Protiva shall be allocated and payable [***] to Licensee and [***] to Protiva; or (ii) if the monetary judgment or settlement is primarily attributable to infringement outside of the Agricultural Field, Protiva shall be entitled to receive from the remainder an amount equal to all direct damages attributable to infringement outside of the Agricultural Field awarded in such judgment or payable under such settlement, Licensee shall then be entitled to receive from the remainder after such payment to Protiva, if any, an amount equal to all direct damages attributable to infringement in the Agricultural Field awarded in such judgment or payable under such settlement; and the balance, if any, remaining after such payments to Protiva and Licensee shall be allocated and payable [***] to Licensee and [***] to Protiva.

18




(c)    Protiva shall use reasonable best efforts to notify Licensee prior to initiating any Project Patent Infringement Action and shall continue to inform Licensee of the status of any Project Patent Infringement Action initiated by Protiva, including by responding to Licensee’s reasonable requests for status reports, providing drafts of substantive filings of Protiva prior to the due date for such filings, and providing copies of substantive filings of any other party to any such Infringement Action promptly after receiving such filings.
(d)    Each Party (as a “Non-Initiating Party”), with respect to a Project Patent Infringement Action initiated by the other Party (as an “Initiating Party”), may join such Infringement Action as a party if it has standing to do so (at its own cost and expense), may retain counsel at its own cost and expense to provide advice to the Non-Initiating Party regarding such Infringement Action, and may share all information regarding the Infringement Action provided by the Initiating Party with such counsel, and, if the Non-Initiating Party has joined such Infringement Action, such counsel shall be permitted to attend meetings, discussions, or other activities relating to the Infringement Action on behalf of the Non-Initiating Party. The Initiating Party agrees to give due consideration to any recommendations or suggestions of the Non-Initiating Party in connection with a Project Patent Infringement Action, but shall not be obligated to implement or follow any such recommendations or suggestions; provided however, that the Initiating Party shall not enter into any settlement or compromise in connection with a Project Patent Infringement Action that would eliminate, diminish, or otherwise modify any right, title, or interest of the Non-Initiating Party in any Protiva Intellectual Property or that would require any payments, concessions, or otherwise bind the Non-Initiating Party, without the Non-Initiating Party’s prior written consent, which consent shall not be unreasonably withheld; for the avoidance of doubt, any settlement or compromise that permits continuation of the Non-Initiating Party’s rights in and to Protiva Intellectual Property in the same manner and subject to the same terms and conditions as set forth in this Agreement shall not require the Non-Initiating Party’s prior consent. The Non-Initiating Party shall provide reasonable cooperation and assistance in connection with a Project Patent Infringement Action initiated by the Initiating Party (including being joined as a party in such Project Patent Infringement Action) at the Initiating Party’s reasonable request and sole cost.
5.5    Defense of Claims Brought by Third Parties. Each Party shall promptly notify the other Party if it becomes aware of any claim that Licensee’s actual use or practice of Compounds or Formulations within the Protiva Intellectual Property, or Licensee’s methods of creating or using such Formulations or Compounds, in connection with its exercise of its license under Section 2.1 infringes, misappropriates, or otherwise violates the intellectual property rights of any Third Party in the Agricultural Field. In any such instance, the Parties shall cooperate and shall mutually agree upon an appropriate course of action; provided, however, that in the absence of any such agreement, (i) any such matter relating to Protiva Project Patents (such matter a “JRC Protiva Project Infringement Matter”) shall be referred to the JRC to be addressed in the manner set forth in the Option Agreement, and (ii) Protiva shall have sole right to determine what action, if any, should be taken in respect of Protiva Background Patents. Each Party shall provide to the other Party copies of any notices it receives from Third Parties regarding any patent nullity actions regarding the Protiva Background Patents or the Protiva Project Patents, any declaratory judgment actions and any alleged infringement or misappropriation of Third Party intellectual property rights arising out of Licensee’s use or practice of the Protiva Intellectual Property in connection with its exercise of

19




its license under Section 2.1. Each Party shall be responsible for its own costs incurred pursuant to this Section 5.5; provided, however, that nothing in this Section 5.5 or elsewhere in this Agreement shall be deemed to eliminate, reduce, or otherwise modify any liability or obligation of Protiva in respect of the Protiva Intellectual Property or Licensee’s (or its Sublicensees’) use or practice of the Protiva Intellectual Property in connection with its exercise of its license under Section 2.1, including but not limited to any such liability or obligation that may arise out of any representation, warranty, or covenant made by Protiva under the Option Agreement or any other Transaction Agreement; and provided further, however, that nothing in this Section 5.5 shall be deemed to limit or eliminate a Party’s right to defend actions initiated by a Third Party against such Party, except to the extent such rights may be limited under any indemnification provisions applicable to such actions.
5.6    Disclosures and Opt-In Rights Regarding Protiva Background Patents. If, during the Term, Protiva decides not to pay the maintenance fee, annuity fee, or similar fee due on any Protiva Background Patent or decides to abandon or discontinue prosecution of any Protiva Background Patent (each a “Proposed Abandonment”) and if (a) such Proposed Abandonment will not be accompanied by the proper filing of a continuation or continuation-in-part application for a Protiva Background Patent and (b) there will be no remaining Protiva Background Patent in the same country or jurisdiction in which the abandoned or discontinued Protiva Background Patent was filed that will substantially maintain the value of Licensee’s exclusive license under the Protiva Background Patents in the Agricultural Field, Protiva shall notify Licensee at least sixty (60) days in advance of any applicable administrative deadline, maintenance fee due date, or response date after or upon which such Protiva Background Patent will be or become abandoned or trigger a similar loss of rights in jurisdictions other than the United States (the “Response Deadline”), such notice to include the Response Deadline. Upon written request of Licensee, Protiva shall promptly assign to Licensee all of its right, title, and interest in and to such Protiva Background Patent unless (x) such Protiva Background Patent is assigned to a Third Party who takes all steps necessary to prevent the Proposed Abandonment and (y) Licensee retains its license to such Protiva Background Patent on the terms and conditions set forth in this Agreement; Protiva shall thereafter have no further right, title, or interest in or to such Protiva Background Patent, except that Protiva shall thereafter have a perpetual, fully paid-up, non-exclusive right and license under such Protiva Background Patent for all uses in the Protiva Field. To the extent necessary or appropriate to prevent the abandonment or similar loss of rights of a Protiva Background Patent assigned or to be assigned to Licensee, Protiva shall take such other steps (including submission of filings or payments on behalf of Licensee or Monsanto) that are reasonably requested by Licensee (or Monsanto), at Licensee’s (or Monsanto’s) sole cost and expense.
5.7    Joint Research Committee Oversight. From and after termination of the Option Agreement, then until the disbandment of the JRC by unanimous vote of the JRC at any time after expiration of the last to expire Valid Claim of a Protiva Project Patent or a Joint Project Patent, the JRC shall remain in existence and shall perform the functions described in this Agreement and any other Transaction Agreements according to the general processes and procedures set out in the Option Agreement (as such processes and procedures may be modified by the unanimous vote of the JRC). For the avoidance of doubt, the JRC’s oversight of Protiva Project Patents shall terminate if this Agreement terminates.

ARTICLE VI –    CONFIDENTIAL INFORMATION AND PUBLICITY
6.1    Non-Disclosure of Confidential Information. Each Party agrees that, for itself and its Affiliates, until the first to occur of (i) [***] or (ii) [***], a Receiving Party shall maintain all Confidential Information of the Disclosing Party in strict confidence and shall not (a) disclose Confidential Information to any third party without the prior written consent of the Disclosing Party, except for disclosures expressly permitted below or (b) use Confidential Information for any purpose except those explicitly licensed or otherwise authorized or permitted by this Agreement or any other Transaction Agreement.
6.2    Exceptions. The obligations in Section 6.1 will not apply with respect to any portion of the Confidential Information that the Receiving Party can show by competent proof: (i) was known to the Receiving Party or its Affiliates, without any obligation to keep it confidential or any restriction on its use, prior to disclosure by the Disclosing Party; (ii) is subsequently disclosed to the Receiving Party or its Affiliates by a Third Party lawfully in possession thereof and without any obligation to keep it confidential or any restriction on its use; (iii) is or otherwise becomes generally available to the public or enters the public domain, either before or after it is disclosed to the Receiving Party and such public availability is not the result, directly or indirectly, of any fault of, or improper taking, use or disclosure by, the Receiving Party or its Affiliates or anyone working in concert or participation with the Receiving Party or its Affiliates; or (iv) has been independently developed by employees or contractors of the Receiving Party or its Affiliates without the aid, application or use of Confidential Information of the Disclosing Party. Specific Confidential Information disclosed by a Disclosing Party will not be deemed to be within any exceptions set forth in (i), (ii), or (iii) above merely because it is embraced by more general information to which one or more of those exceptions may apply and provided further that no combination of information shall be deemed to be within any such exceptions unless the combination itself and its principle of operation are within the public domain. Even though Confidential Information may be within one of the exceptions described in the preceding sentence, the Receiving Party shall not disclose to third parties that the excepted Confidential Information was received from the Disclosing Party.
6.3    Permitted Uses. Confidential Information of a Disclosing Party may be used by the Receiving Party in the performance of its obligations under any Transaction Agreement, as otherwise expressly authorized in any Transaction Agreement or as expressly authorized by the Disclosing Party in writing. Confidential Information that is Protiva Intellectual Property may be used by Licensee subject to and in accordance with the provisions of this Agreement applicable to Licensee’s license to Protiva Intellectual Property. Licensee shall take steps to maintain the confidentiality of such Confidential Information that are consistent with the steps it takes to maintain the confidentiality of its own most-valuable confidential information, but in no event less than commercially reasonable steps; provided, however, that nothing in this Agreement shall be deemed to eliminate, restrict, or otherwise limit Licensee’s license to use such Confidential Information in accordance with the terms and conditions of this Agreement, even if such use may result, directly or indirectly, in the disclosure of such Confidential Information, so long as such disclosures are made in a manner than complies with Section 6.4 below.

21




6.4    Permitted Disclosures    . The Receiving Party may disclose Confidential Information belonging to the Disclosing Party to the extent (and only to the extent) such disclosure is reasonably necessary in the following instances: (i) subject to the proviso below, by any Party hereto, in order to comply with applicable non-patent law (including any securities law or regulation or the rules of a securities exchange in a relevant jurisdiction) and with judicial process, if based on the reasonable advice of the Receiving Party’s counsel, such disclosure is necessary for such compliance; (ii) subject to the proviso below, by any Party hereto, in connection with prosecuting or defending litigation; (iii) by any Party hereto, in connection with filing and prosecuting Protiva Project Patents and Joint Project Patents only in a manner that complies with such Party’s rights and obligations in connection with such matters as set out in the Transaction Agreements; (iv) subject to the proviso below, by Licensee, its Sublicensees, or their sublicensees in connection with any legal or regulatory requirements related to the development, sale, offer for sale, use or manufacture of commercial products (or potential commercial products) that use or employ Protiva Intellectual Property, such as labeling requirements, disclosures in connection with obtaining regulatory approvals, and the like, so long as the discovery, development, use, manufacture, and commercialization of such products has been and is performed in a manner that complies with the terms and conditions of Licensee’s license to such Protiva Intellectual Property and reasonable steps shall be taken to maintain the confidentiality of said Confidential Information even when disclosed for legal or regulatory purposes; (v) subject to the proviso below, by the Licensee, to its Affiliates, permitted acquirers or assignees under the Transaction Agreements and its or any of their research collaborators, subcontractors, lenders (but, with respect to lenders, only Confidential Information related to the terms and conditions of the Transaction Agreements and financial information related thereto), and each of the Licensee’s and its Affiliates’ respective directors, employees, contractors and agents; and (vi) subject to the proviso below, by Protiva, to its Affiliates, permitted acquirers or assignees under the Transaction Agreements and its or any of their research collaborators, subcontractors, lenders (but, with respect to lenders, only Confidential Information related to the terms and conditions of the Transaction Agreements and financial information related thereto), and Protiva’s and its Affiliates’ respective directors, employees, contractors and agents, provided, that (a) with respect to clause (i), (ii) and (iv) where legally permissible, (1) the Receiving Party shall notify the Disclosing Party of the Receiving Party’s intent to make any disclosure pursuant thereto sufficiently prior to making such disclosure so as to allow the Disclosing Party adequate time to take whatever action it may deem appropriate to protect the confidentiality of the information to be disclosed, and (2) consistent with applicable law or regulation, the Disclosing Party shall have the right to suggest reasonable changes to the disclosure to protect its interests and the Receiving Party shall not unreasonably refuse to include such changes in its disclosure, and (b) with respect to clause (v) and (vi), each Person to whom Confidential Information is disclosed must be bound prior to disclosure by confidentiality and non-use restrictions at least as restrictive as those contained in this Agreement (other than investment bankers, investors and lenders, who must be bound prior to disclosure by commercially reasonable obligations of confidentiality).
ARTICLE VII –    INDEMNIFICATION AND INSURANCE
7.1    Protiva Indemnification. Protiva agrees to indemnify Licensee and its Affiliates, and their respective agents, directors, officers, employees, representatives, successors and permitted assigns (the “Licensee Indemnitees”) against and to hold each of them harmless from any and all

22




losses, costs, damages, fees or expenses (“Losses”) actually incurred or suffered by an Licensee Indemnitee to the extent arising out of or in connection with any claim, suit, demand, investigation or proceeding brought by a Third Party based on any breach of any representation, warranty or covenant by Protiva under this Agreement or Protiva’s gross negligence or willful misconduct. The foregoing indemnification shall not apply to the extent that any Losses are due to (a) a breach of any of Licensee’s representations, warranties, covenants and/or obligations under this Agreement or (b) Licensee’s gross negligence or willful misconduct.
7.2    Licensee Indemnification. Licensee agrees to indemnify Protiva and its Affiliates, and their respective agents, directors, officers, employees, representatives, successors and permitted assigns (the “Protiva Indemnitees”) against and to hold each of them harmless from any and all Losses actually incurred or suffered by a Protiva Indemnitee to the extent arising out of or in connection with (a) any claim, suit, demand, investigation or proceeding brought by a Third Party based on (i) any breach of any representation, warranty or covenant by Licensee under this Agreement, or (ii) Licensee’s gross negligence or willful misconduct, or (b) a Third Party’s direct damages resulting from any development or Commercialization of any Product or products or processes that use or employ Protiva Intellectual Property. In addition to the limitations set forth in the preceding sentence, the foregoing indemnification obligations shall not apply to the extent that any Losses are due to (x) a breach of any of Protiva’s representations, warranties, covenants and/or obligations under this Agreement, (y) Protiva’s gross negligence or willful misconduct, or (z) any of the following occurring prior to or at Closing: (A) any breach of any representation, warranty or covenant by Licensee under this Agreement; (B) Licensee’s gross negligence or willful misconduct; or (C) a breach of any of Protiva’s representations, warranties, or covenants directed to Protiva Intellectual Property or the Protiva License under the Option Agreement.
7.3    Tender of Defense; Counsel. Any Person (the “Indemnified Party”) seeking indemnification under Article VII agrees to give prompt notice in writing to the other Party (the “Indemnifying Party”) of the assertion of any claim or the commencement of any action by any third party (a “Third Party Claim”) in respect of which indemnity may be sought under such section. Such notice shall set forth in reasonable detail such Third Party Claim and the basis for indemnification (taking into account the information then available to the Indemnified Party). The failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations hereunder, except to the extent such failure shall have materially and adversely prejudiced the Indemnifying Party. The Indemnifying Party shall be entitled to participate in the defense of any Third Party Claim and shall, upon its written confirmation of its obligation to indemnify the Indemnified Party in accordance with this Article VII, be entitled to control and appoint lead counsel reasonably satisfactory to the Indemnified Party for such defense by written notice to the Indemnified Party within twenty (20) calendar days after the Indemnifying Party has received notice of the Third Party Claim, in each case at its own expense; provided, however, that the Indemnifying Party must conduct the defense of the Third Party Claim actively and diligently thereafter in order to preserve its rights in this regard. The Indemnifying Party shall not be entitled to assume or maintain control of the defense of any Third Party Claim and shall pay the fees and expenses of one counsel retained by the Indemnified Party if: (a) the Third Party Claim relates to or arises in connection with any criminal proceeding, action, indictment or allegation, (b) the Third Party Claim seeks an injunction or equitable relief against a Indemnified Party or any of its Affiliates, or (c) the Indemnifying Party

23




has failed or is failing to prosecute or defend vigorously the Third Party Claim. Each Indemnified Party shall obtain the prior written consent of the Indemnifying Party, such consent not to be unreasonably withheld, delayed or conditioned, before entering into any settlement of a Third Party Claim. Notwithstanding the foregoing, the Indemnifying Party shall not be entitled to enter into or approve any settlement of a Third Party Claim without the consent of the Indemnified Party (which may be withheld in its sole discretion), if the settlement (a) does not expressly unconditionally release all applicable Indemnified Parties and their Affiliates from all Liabilities with respect to such Third Party Claim or (b) imposes injunctive or other equitable relief against the Indemnified Party or any of its Affiliates, (c) involves any admission of criminal or similar liability, or (d) involves any monetary damages that may not be fully covered by the Indemnifying Party. In the event that the Indemnifying Party fails to assume the defense of the Third Party Claim in accordance with this Section 7.3, (a) the Indemnified Party may defend against the Third Party Claim in any manner it reasonably may deem appropriate, and (b) the Indemnifying Party will remain responsible for any Losses of the Indemnified Party as a result of such Third Party Claim. In circumstances where the Indemnifying Party is controlling the defense of a Third Party Claim in accordance with this Section 7.3, the Indemnified Party shall be entitled to participate in the defense of any Third Party Claim and to employ separate counsel of its choice for such purpose, in which case the fees and expenses of such separate counsel shall be borne by such Indemnified Party. Notwithstanding anything herein to the contrary, in circumstances where there is a conflict of interest that would reasonably make it inappropriate under applicable standards of professional conduct to have common counsel for the Indemnifying Party and the Indemnified Party, the Indemnified Party shall be entitled to employ separate counsel, that is reasonably acceptable to the Indemnifying Party, and the Indemnifying Party shall pay the reasonable fees and expenses of such separate counsel. Each Party shall cooperate, and cause their respective Affiliates to cooperate in all reasonable respects, in the defense or prosecution of any Third Party Claim and shall furnish or cause to be furnished such records, information and testimony, and attend such conferences, discovery proceedings, hearings, trials or appeals, as may be reasonably requested in connection therewith.
7.4    Insurance. Each Party shall maintain insurance, including product liability insurance, with respect to its activities under this Agreement regarding Products in such amount as such Party customarily maintains with respect to similar activities for its other products. Each Party shall maintain such insurance for so long as it continues its activities under this Agreement, and thereafter for so long as such Party customarily maintains insurance for itself covering similar activities for its other products. Notwithstanding the foregoing, the Parties agree that during such time that Licensee is an Affiliate of Protiva, Licensee shall have satisfied its obligations under this Section 7.4 provided it is covered by Protiva’s existing insurance policies.
ARTICLE VIII –    TERM AND TERMINATION
8.1    Term. The term of this Agreement (the “Term”) shall begin on the Original Effective Date and, unless terminated earlier as provided herein, shall continue in perpetuity.
8.2    Termination for Material Breach. In the event of a material breach of this Agreement by Licensee, Protiva may provide notice to Licensee setting forth the nature of the breach and a description of the facts underlying the breach sufficient to identify the breach. If Licensee has not

24




cured such breach or proposed a reasonably satisfactory plan to cure or otherwise remedy such breach within ninety (90) days from the date of receipt of such notice of breach, Protiva may provide a notice of termination to Licensee and this Agreement shall terminate ninety (90) days after such notice of termination unless the breach is cured to the reasonable satisfaction of Protiva or unless Licensee has begun to implement a reasonably satisfactory plan to cure or otherwise remedy such breach within ninety (90) days from the receipt of such notice of termination. Notwithstanding the foregoing, or any termination of Licensee’s license pursuant to Section 8.4 below, with respect to any sublicense entered into by Licensee for which the Sublicensee is not the cause of the material breach that resulted in the termination of this Agreement, then upon the assignment to Protiva of all rights of Licensee under such sublicense, Protiva shall assume those obligations of Licensee to such Sublicensee under such sublicense that are within the scope of Protiva’s obligations to Licensee under this Agreement; all other obligations to the Sublicensee under such sublicense, and all liabilities of Licensee to such Sublicensee, shall remain the sole and exclusive obligations and liabilities of Protiva, and nothing in this Section 8.2 shall be deemed to expand, increase, or otherwise modify Protiva’s obligations or liabilities under this Agreement.
8.3    Challenges of Protiva’s Patents. If Licensee or any of its Affiliates shall (a) commence or participate in any action or proceeding (including any patent opposition or re-examination proceeding), or otherwise assert in writing any claim, challenging or denying the validity of any of the Protiva Background Patents or Protiva Project Patents or any claim thereof or (b) actively assist any other Person in bringing or prosecuting any action or proceeding (including any patent opposition or re-examination proceeding) challenging or denying the validity of such Patents or any claim thereof, Protiva will have the right to give notice to Licensee (which notice must be given, if at all, within ninety (90) days after Arbutus’s CEO first learns of the foregoing) that the licenses granted by Protiva to such Patent will terminate in ninety (90) days following such notice, and, unless Licensee and/or its Affiliate, as applicable, withdraws or causes to be withdrawn all such challenge(s) within such ninety-day period, such licenses will so terminate.
8.4    Rights in Bankruptcy. Each Party (the “Insolvent Party”) shall promptly notify the other Party (the “Solvent Party”) in writing upon the initiation of any proceeding in bankruptcy, reorganization, dissolution, liquidation or arrangement for the appointment of a receiver or trustee to take possession of the assets of the Insolvent Party or similar proceeding under the law for release of creditors by or against the Insolvent Party or if the Insolvent Party shall make a general assignment for the benefit of its creditors. To the extent permitted by Applicable Law, if the applicable circumstances described above shall have continued for ninety (90) days undismissed, unstayed, unbonded and undischarged, the Solvent Party may terminate this Agreement upon written notice to the Insolvent Party at any time. If Protiva is the Insolvent Party, the rights and remedies granted to Licensee (as the Solvent Party) pursuant to this Section 8.4 shall be in addition to, and not in lieu of, Licensee’s rights and remedies under Section 2.4 above.
8.5    Consequences of Termination; Survival.
(a)    In the event this Agreement is properly terminated in accordance with its terms, then except as provided in the Protiva-Monsanto Services Agreement, Licensee’s rights and licenses under the Protiva Intellectual Property shall terminate upon the effective date of such termination.

25




Termination of this Agreement shall not relieve the Parties of any obligation accruing prior to or upon such expiration or termination and the provisions of ARTICLE I – (Definitions), ARTICLE VI – (Confidential Information), ARTICLE VII – (Indemnification), and ARTICLE IX – (Miscellaneous) shall survive any expiration or termination of this Agreement.
(b)    Notwithstanding anything to the contrary contained in this Agreement, if it is determined that Protiva has breached its representation and warranty in Section 9.1(b)(iii), Licensee’s sole and exclusive remedy shall be to require Arbutus or its Affiliate, as applicable, to grant to Licensee a license under its Patents or Know-How for all purposes in the Agricultural Field and such Patents and/or Know-How shall thereafter be included within Protiva Intellectual Property for all purpose of this Agreement; provided, however, that the foregoing shall not be deemed to limit, eliminate or otherwise modify Protiva’s obligations under Section 7.1 to indemnify any Licensee Indemnitee against or hold any Licensee Indemnitee harmless in respect of any Losses actually incurred or suffered by a Licensee Indemnitee arising out of or in connection with any claim, suit, demand, investigation or proceeding brought by UBC or any other Third Party based on any breach of any representation, warranty or covenant by Protiva under this Agreement, including Section 9.1(b)(vi), even if or to the extent such Losses may also arise out Protiva’s breach of Section 9.1(b)(iii). Furthermore, omission from the Technology Transfer Compound List of any Compound or Formulation that was provided or created by Protiva or its Affiliate in connection with the Research Program shall not be deemed to limit or eliminate Licensee’s rights under the second sentence of Section 2.1 with respect to such Compound or Formulation.
8.6    Remedies. The Parties acknowledge and agree that, in the event of a breach or a threatened breach by either Party of this Agreement for which it will have no adequate remedy at law, the other Party may suffer irreparable damage and, accordingly, shall be entitled to injunctive and other equitable remedies to prevent or restrain such breach or threatened breach, in addition to any other remedy they might have at law or at equity. In the event of a breach or threatened breach by a Party of any such provision, the other Party shall be authorized and entitled to obtain from any court of competent jurisdiction injunctive relief, whether preliminary or permanent, arising from such breach, which rights shall be cumulative and in addition to any other rights or remedies to which the other Party may be entitled in law or equity.

EXHIBIT M
FIRST AMENDMENT
TO
PROTIVA-MONSANTO SERVICES AGREEMENT

THIS FIRST AMENDMENT TO THE PROTIVA-MONSANTO SERVICES AGREEMENT (this “Amendment”) is made and entered into as of March 4, 2016, (the “Effective Date”) by and among Protiva Biotherapeutics, Inc., a British Columbia corporation (“Protiva”) and a wholly-owned subsidiary of Arbutus Biopharma Corporation, formerly Tekmira Pharmaceutcals Corporation (“Arbutus”), Protiva Agricultural Development Company Inc. (“PadCo”), a British Columbia corporation and a wholly-owned subsidiary of Protiva (the “Company”), and Monsanto Company, a Delaware corporation (“Monsanto”).

WHEREAS, Protiva, the Company and Monsanto entered into that certain Protiva-Monsanto Services Agreement on January 12, 2014 (the “Agreement”), and, contemporaneously with the execution of the Agreement: (a) Protiva, Arbutus, PadCo and Monsanto Canada entered into the Option Agreement and (b) PadCo, Protiva and Tekmira entered into the PadCo-Protiva License and Services Agreement;
WHEREAS, contemporaneously with the execution of this Amendment and as of the Effective Date: (a) the parties to the PadCo-Protiva License and Services Agreement are amending and restating the PadCo-Protiva License and Services Agreement, (b) the parties to the Option Agreement are amending and restating the Option Agreement, (c) Monsanto is exercising the Call Option to acquire all of the outstanding capital stock of PadCo, and (d) Closing is occurring;
WHEREAS, Protiva, the Company and Monsanto desire to amend the Agreement, effective as of the Effective Date, as set forth herein; and
NOW THEREFORE, in consideration of the representations, warranties, covenants and agreements contained herein, and for other valuable consideration, the receipt and adequacy of which is hereby acknowledged, the parties mutually agree to amend and modify the Agreement as follows:

1.    All capitalized terms used in this Amendment, unless otherwise defined, shall have the meanings ascribed to such terms in the Agreement. In addition, the following terms shall have the following meanings for purposes of this Amendment:
(a)    “Monsanto New Improvement” means an invention that is (i) Monsanto New Intellectual Property, (ii) claimed in an issued patent owned by Monsanto and having a priority date that is on or after the Effective Date, and (iii) the practice of which, if practiced at the time of said priority date, would be covered by at least one Valid Claim of a Patent that is a Protiva Background Patent or Protiva Project Patent.

35




(b)    “Monsanto New Intellectual Property” means all inventions that are conceived by Monsanto Personnel on or after the Effective Date and that are covered by at least one Valid Claim of a Patent. For the avoidance of doubt inventions that were conceived by Monsanto Personnel in the conduct of activities under the Research Program and that are not Joint Project Intellectual Property are Monsanto Project Intellectual Property and not Monsanto New Intellectual Property.
2.    The Parties acknowledge and agree that, as of the Effective Date, Monsanto Canada is exercising the Call Option prior to completion of Phase C (as such term is defined in the Research Program). Monsanto hereby elects to terminate research under the Research Plan as of the Effective Date and, therefore, the Parties acknowledge and agree that, on and as of the Effective Date, the Term of the Agreement shall be deemed to expire.
3.    The following new subsection (c) is hereby added to Section 4.2 of the Agreement:
“(c)    an irrevocable, worldwide, perpetual (subject to Sections 8.3 and 8.4), royalty-free, transferrable (subject to Section 9.1 below) license, with right to sublicense (subject to Section 4.3 below), in and to any Monsanto New Improvements for all purposes in the Protiva Field, which license shall be exclusive, other than in respect of any Monsanto New Improvements that Monsanto is obligated to license to a third party pursuant to any agreement in existence as of the Effective Date, in which case such license shall be non-exclusive.
4.    References to “Monsanto Improvements” in Sections 4.1, 4.3, 4.7, 4.9, 4.10, 6.2, and 8.3(ii) of the Agreement shall be deemed to also refer to and include Monsanto New Improvements.
5.    References to “Monsanto Project Intellectual Property” in Sections 4.1, 4.4, and 4.5 of the Agreement shall be deemed to also refer to and include Monsanto New Intellectual Property.
6.    In all other respects, the terms, conditions, and covenants of the Agreement shall remain unchanged and any rights that either of the Parties may have under the Agreement shall remain in full force and effect.
7.    This Amendment may be executed in two or more counterparts, each of which will be deemed an original and all of which together will constitute one and the same instrument. Each shall be considered signed when the signature of a Party is delivered by facsimile, electronic signature or electronic (email) transmission to the other Parties, when it is delivered in a manner that reasonably identifies the signatory as the Party named. Such electronic signatures shall be treated in all respects as having the same effect as an original signature. If requested by any Party, documents bearing an original signature may be subsequently and promptly submitted to replace copies bearing electronic signatures. By signing this Amendment the representatives of each Party thereby represent that such Person is duly authorized by the Party in question to execute this Amendment on behalf of such Party and that each respective Party agrees to be bound by the provisions thereof. The Parties to this document agree that a copy of the original signature (including

36




an electronic copy) may be used for any and all purposes for which the original signature may have been used.

11




Agreement, and such Patent or Know-How shall thereafter be included in Protiva Intellectual Property for all purposes of this Agreement. For the avoidance of doubt, (a) Protiva has not granted to Licensee any right or license to the Protiva Intellectual Property outside of the Agricultural Field, (b) Licensee shall have the right to develop and manufacture Compounds and Formulations in connection with the exercise of its rights to Discover, Develop, Commercialize and Manufacture Products, and to discover, develop, commercialize, and manufacture other products and processes that use or employ Protiva Intellectual Property, in the Agricultural Field, and (c) all UBC IP is expressly excluded from this Agreement, and Licensee is not granted any rights in or to any UBC IP, other than as may be granted pursuant to the second sentence of this Section 2.1.

17




Protiva shall be entitled to receive from the remainder an amount equal to all direct damages attributable to infringement outside of the Agricultural Field awarded in such judgment or payable under such settlement, Licensee shall then be entitled to receive from the remainder after such payment to Protiva, if any, an amount equal to all direct damages attributable to infringement in the Agricultural Field awarded in such judgment or payable under such settlement; and the balance, if any, remaining after such payments to Protiva and Licensee shall be allocated and payable [***] to Licensee and [***] to Protiva.
(c)    Protiva shall use reasonable best efforts to notify Licensee prior to initiating any Project Patent Infringement Action and shall continue to inform Licensee of the status of any Project Patent Infringement Action initiated by Protiva, including by responding to Licensee’s reasonable requests for status reports, providing drafts of substantive filings of Protiva prior to the due date for such filings, and providing copies of substantive filings of any other party to any such Infringement Action promptly after receiving such filings.
(d)    Each Party (as a “Non-Initiating Party”), with respect to a Project Patent Infringement Action initiated by the other Party (as an “Initiating Party”), may join such Infringement Action as a party if it has standing to do so (at its own cost and expense), may retain counsel at its own cost and expense to provide advice to the Non-Initiating Party regarding such Infringement Action, and may share all information regarding the Infringement Action provided by the Initiating Party with such counsel, and, if the Non-Initiating Party has joined such Infringement Action, such counsel shall be permitted to attend meetings, discussions, or other activities relating to the Infringement Action on behalf of the Non-Initiating Party. The Initiating Party agrees to give due consideration to any recommendations or suggestions of the Non-Initiating Party in connection with a Project Patent Infringement Action, but shall not be obligated to implement or follow any such recommendations or suggestions; provided however, that the Initiating Party shall not enter into any settlement or compromise in connection with a Project Patent Infringement Action that would eliminate, diminish, or otherwise modify any right, title, or interest of the Non-Initiating Party in any Protiva Intellectual Property or that would require any payments, concessions, or otherwise bind the Non-Initiating Party, without the Non-Initiating Party’s prior written consent, which consent shall not be unreasonably withheld; for the avoidance of doubt, any settlement or compromise that permits continuation of the Non-Initiating Party’s rights in and to Protiva Intellectual Property in the same manner and subject to the same terms and conditions as set forth in this Agreement shall not require the Non-Initiating Party’s prior consent. The Non-Initiating Party shall provide reasonable cooperation and assistance in connection with a Project Patent Infringement Action initiated by the Initiating Party (including being joined as a party in such Project Patent Infringement Action) at the Initiating Party’s reasonable request and sole cost.
5.5    Defense of Claims Brought by Third Parties    . Each Party shall promptly notify the other Party if it becomes aware of any claim that Licensee’s actual use or practice of Compounds or Formulations within the Protiva Intellectual Property, or Licensee’s methods of creating or using such Formulations or Compounds, in connection with its exercise of its license under Section 2.1 infringes, misappropriates, or otherwise violates the intellectual property rights of any Third Party in the Agricultural Field. In any such instance, the Parties shall cooperate and shall mutually agree upon an appropriate course of action; provided, however, that in the absence of any such agreement,

18




(i) any such matter relating to Protiva Project Patents (such matter a “JRC Protiva Project Infringement Matter”) shall be referred to the JRC to be addressed in the manner set forth in the Option Agreement, and (ii) Protiva shall have sole right to determine what action, if any, should be taken in respect of Protiva Background Patents. Each Party shall provide to the other Party copies of any notices it receives from Third Parties regarding any patent nullity actions regarding the Protiva Background Patents or the Protiva Project Patents, any declaratory judgment actions and any alleged infringement or misappropriation of Third Party intellectual property rights arising out of Licensee’s use or practice of the Protiva Intellectual Property in connection with its exercise of its license under Section 2.1. Each Party shall be responsible for its own costs incurred pursuant to this Section 5.5; provided, however, that nothing in this Section 5.5 or elsewhere in this Agreement shall be deemed to eliminate, reduce, or otherwise modify any liability or obligation of Protiva in respect of the Protiva Intellectual Property or Licensee’s (or its Sublicensees’) use or practice of the Protiva Intellectual Property in connection with its exercise of its license under Section 2.1, including but not limited to any such liability or obligation that may arise out of any representation, warranty, or covenant made by Protiva under the Option Agreement or any other Transaction Agreement; and provided further, however, that nothing in this Section 5.5 shall be deemed to limit or eliminate a Party’s right to defend actions initiated by a Third Party against such Party, except to the extent such rights may be limited under any indemnification provisions applicable to such actions.
5.6    Disclosures and Opt-In Rights Regarding Protiva Background Patents. If, during the Term, Protiva decides not to pay the maintenance fee, annuity fee, or similar fee due on any Protiva Background Patent or decides to abandon or discontinue prosecution of any Protiva Background Patent (each a “Proposed Abandonment”) and if (a) such Proposed Abandonment will not be accompanied by the proper filing of a continuation or continuation-in-part application for a Protiva Background Patent and (b) there will be no remaining Protiva Background Patent in the same country or jurisdiction in which the abandoned or discontinued Protiva Background Patent was filed that will substantially maintain the value of Licensee’s exclusive license under the Protiva Background Patents in the Agricultural Field, Protiva shall notify Licensee at least sixty (60) days in advance of any applicable administrative deadline, maintenance fee due date, or response date after or upon which such Protiva Background Patent will be or become abandoned or trigger a similar loss of rights in jurisdictions other than the United States (the “Response Deadline”), such notice to include the Response Deadline. Upon written request of Licensee, Protiva shall promptly assign to Licensee all of its right, title, and interest in and to such Protiva Background Patent unless (x) such Protiva Background Patent is assigned to a Third Party who takes all steps necessary to prevent the Proposed Abandonment and (y) Licensee retains its license to such Protiva Background Patent on the terms and conditions set forth in this Agreement; Protiva shall thereafter have no further right, title, or interest in or to such Protiva Background Patent, except that Protiva shall thereafter have a perpetual, fully paid-up, non-exclusive right and license under such Protiva Background Patent for all uses in the Protiva Field. To the extent necessary or appropriate to prevent the abandonment or similar loss of rights of a Protiva Background Patent assigned or to be assigned to Licensee, Protiva shall take such other steps (including submission of filings or payments on behalf of Licensee or Monsanto) that are reasonably requested by Licensee (or Monsanto), at Licensee’s (or Monsanto’s) sole cost and expense.

19




5.7    Joint Research Committee Oversight. From and after termination of the Option Agreement, then until the disbandment of the JRC by unanimous vote of the JRC at any time after expiration of the last to expire Valid Claim of a Protiva Project Patent or a Joint Project Patent, the JRC shall remain in existence and shall perform the functions described in this Agreement and any other Transaction Agreements according to the general processes and procedures set out in the Option Agreement (as such processes and procedures may be modified by the unanimous vote of the JRC). For the avoidance of doubt, the JRC’s oversight of Protiva Project Patents shall terminate if this Agreement terminates.
ARTICLE VI –    CONFIDENTIAL INFORMATION AND PUBLICITY
6.1    Non-Disclosure of Confidential Information    . Each Party agrees that, for itself and its Affiliates, until the first to occur of (i) [***] or (ii) [***], a Receiving Party shall maintain all Confidential Information of the Disclosing Party in strict confidence and shall not (a) disclose Confidential Information to any third party without the prior written consent of the Disclosing Party, except for disclosures expressly permitted below or (b) use Confidential Information for any purpose except those explicitly licensed or otherwise authorized or permitted by this Agreement or any other Transaction Agreement.
6.2    Exceptions    . The obligations in Section 6.1 will not apply with respect to any portion of the Confidential Information that the Receiving Party can show by competent proof: (i) was known to the Receiving Party or its Affiliates, without any obligation to keep it confidential or any restriction on its use, prior to disclosure by the Disclosing Party; (ii) is subsequently disclosed to the Receiving Party or its Affiliates by a Third Party lawfully in possession thereof and without any obligation to keep it confidential or any restriction on its use; (iii) is or otherwise becomes generally available to the public or enters the public domain, either before or after it is disclosed to the Receiving Party and such public availability is not the result, directly or indirectly, of any fault of, or improper taking, use or disclosure by, the Receiving Party or its Affiliates or anyone working in concert or participation with the Receiving Party or its Affiliates; or (iv) has been independently developed by employees or contractors of the Receiving Party or its Affiliates without the aid, application or use of Confidential Information of the Disclosing Party. Specific Confidential Information disclosed by a Disclosing Party will not be deemed to be within any exceptions set forth in (i), (ii), or (iii) above merely because it is embraced by more general information to which one or more of those exceptions may apply and provided further that no combination of information shall be deemed to be within any such exceptions unless the combination itself and its principle of operation are within the public domain. Even though Confidential Information may be within one of the exceptions described in the preceding sentence, the Receiving Party shall not disclose to third parties that the excepted Confidential Information was received from the Disclosing Party.
6.3    Permitted Uses. Confidential Information of a Disclosing Party may be used by the Receiving Party in the performance of its obligations under any Transaction Agreement, as otherwise expressly authorized in any Transaction Agreement or as expressly authorized by the Disclosing Party in writing. Confidential Information that is Protiva Intellectual Property may be used by Licensee subject to and in accordance with the provisions of this Agreement applicable to Licensee’s license to Protiva Intellectual Property. Licensee shall take steps to maintain the confidentiality of

20




such Confidential Information that are consistent with the steps it takes to maintain the confidentiality of its own most-valuable confidential information, but in no event less than commercially reasonable steps; provided, however, that nothing in this Agreement shall be deemed to eliminate, restrict, or otherwise limit Licensee’s license to use such Confidential Information in accordance with the terms and conditions of this Agreement, even if such use may result, directly or indirectly, in the disclosure of such Confidential Information, so long as such disclosures are made in a manner than complies with Section 6.4 below.
6.4    Permitted Disclosures. The Receiving Party may disclose Confidential Information belonging to the Disclosing Party to the extent (and only to the extent) such disclosure is reasonably necessary in the following instances: (i) subject to the proviso below, by any Party hereto, in order to comply with applicable non-patent law (including any securities law or regulation or the rules of a securities exchange in a relevant jurisdiction) and with judicial process, if based on the reasonable advice of the Receiving Party’s counsel, such disclosure is necessary for such compliance; (ii) subject to the proviso below, by any Party hereto, in connection with prosecuting or defending litigation; (iii) by any Party hereto, in connection with filing and prosecuting Protiva Project Patents and Joint Project Patents only in a manner that complies with such Party’s rights and obligations in connection with such matters as set out in the Transaction Agreements; (iv) subject to the proviso below, by Licensee, its Sublicensees, or their sublicensees in connection with any legal or regulatory requirements related to the development, sale, offer for sale, use or manufacture of commercial products (or potential commercial products) that use or employ Protiva Intellectual Property, such as labeling requirements, disclosures in connection with obtaining regulatory approvals, and the like, so long as the discovery, development, use, manufacture, and commercialization of such products has been and is performed in a manner that complies with the terms and conditions of Licensee’s license to such Protiva Intellectual Property and reasonable steps shall be taken to maintain the confidentiality of said Confidential Information even when disclosed for legal or regulatory purposes; (v) subject to the proviso below, by the Licensee, to its Affiliates, permitted acquirers or assignees under the Transaction Agreements and its or any of their research collaborators, subcontractors, lenders (but, with respect to lenders, only Confidential Information related to the terms and conditions of the Transaction Agreements and financial information related thereto), and each of the Licensee’s and its Affiliates’ respective directors, employees, contractors and agents; and (vi) subject to the proviso below, by Protiva, to its Affiliates, permitted acquirers or assignees under the Transaction Agreements and its or any of their research collaborators, subcontractors, lenders (but, with respect to lenders, only Confidential Information related to the terms and conditions of the Transaction Agreements and financial information related thereto), and Protiva’s and its Affiliates’ respective directors, employees, contractors and agents, provided, that (a) with respect to clause (i), (ii) and (iv) where legally permissible, (1) the Receiving Party shall notify the Disclosing Party of the Receiving Party’s intent to make any disclosure pursuant thereto sufficiently prior to making such disclosure so as to allow the Disclosing Party adequate time to take whatever action it may deem appropriate to protect the confidentiality of the information to be disclosed, and (2) consistent with applicable law or regulation, the Disclosing Party shall have the right to suggest reasonable changes to the disclosure to protect its interests and the Receiving Party shall not unreasonably refuse to include such changes in its disclosure, and (b) with respect to clause (v) and (vi), each Person to whom Confidential Information is disclosed must be bound prior to disclosure by confidentiality and non-use restrictions at least as restrictive as those contained

21




in this Agreement (other than investment bankers, investors and lenders, who must be bound prior to disclosure by commercially reasonable obligations of confidentiality).
ARTICLE VII –    INDEMNIFICATION AND INSURANCE
7.1    Protiva Indemnification    . Protiva agrees to indemnify Licensee and its Affiliates, and their respective agents, directors, officers, employees, representatives, successors and permitted assigns (the “Licensee Indemnitees”) against and to hold each of them harmless from any and all losses, costs, damages, fees or expenses (“Losses”) actually incurred or suffered by an Licensee Indemnitee to the extent arising out of or in connection with any claim, suit, demand, investigation or proceeding brought by a Third Party based on any breach of any representation, warranty or covenant by Protiva under this Agreement or Protiva’s gross negligence or willful misconduct. The foregoing indemnification shall not apply to the extent that any Losses are due to (a) a breach of any of Licensee’s representations, warranties, covenants and/or obligations under this Agreement or (b) Licensee’s gross negligence or willful misconduct.
7.2    Licensee Indemnification. Licensee agrees to indemnify Protiva and its Affiliates, and their respective agents, directors, officers, employees, representatives, successors and permitted assigns (the “Protiva Indemnitees”) against and to hold each of them harmless from any and all Losses actually incurred or suffered by a Protiva Indemnitee to the extent arising out of or in connection with (a) any claim, suit, demand, investigation or proceeding brought by a Third Party based on (i) any breach of any representation, warranty or covenant by Licensee under this Agreement, or (ii) Licensee’s gross negligence or willful misconduct, or (b) a Third Party’s direct damages resulting from any development or Commercialization of any Product or products or processes that use or employ Protiva Intellectual Property. In addition to the limitations set forth in the preceding sentence, the foregoing indemnification obligations shall not apply to the extent that any Losses are due to (x) a breach of any of Protiva’s representations, warranties, covenants and/or obligations under this Agreement, (y) Protiva’s gross negligence or willful misconduct, or (z) any of the following occurring prior to or at Closing: (A) any breach of any representation, warranty or covenant by Licensee under this Agreement; (B) Licensee’s gross negligence or willful misconduct; or (C) a breach of any of Protiva’s representations, warranties, or covenants directed to Protiva Intellectual Property or the Protiva License under the Option Agreement.
7.3    Tender of Defense; Counsel    . Any Person (the “Indemnified Party”) seeking indemnification under Article VII agrees to give prompt notice in writing to the other Party (the “Indemnifying Party”) of the assertion of any claim or the commencement of any action by any third party (a “Third Party Claim”) in respect of which indemnity may be sought under such section. Such notice shall set forth in reasonable detail such Third Party Claim and the basis for indemnification (taking into account the information then available to the Indemnified Party). The failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations hereunder, except to the extent such failure shall have materially and adversely prejudiced the Indemnifying Party. The Indemnifying Party shall be entitled to participate in the defense of any Third Party Claim and shall, upon its written confirmation of its obligation to indemnify the Indemnified Party in accordance with this Article VII, be entitled to control and appoint lead counsel reasonably satisfactory to the Indemnified Party for such defense by written notice to the Indemnified

22




Party within twenty (20) calendar days after the Indemnifying Party has received notice of the Third Party Claim, in each case at its own expense; provided, however, that the Indemnifying Party must conduct the defense of the Third Party Claim actively and diligently thereafter in order to preserve its rights in this regard. The Indemnifying Party shall not be entitled to assume or maintain control of the defense of any Third Party Claim and shall pay the fees and expenses of one counsel retained by the Indemnified Party if: (a) the Third Party Claim relates to or arises in connection with any criminal proceeding, action, indictment or allegation, (b) the Third Party Claim seeks an injunction or equitable relief against a Indemnified Party or any of its Affiliates, or (c) the Indemnifying Party has failed or is failing to prosecute or defend vigorously the Third Party Claim. Each Indemnified Party shall obtain the prior written consent of the Indemnifying Party, such consent not to be unreasonably withheld, delayed or conditioned, before entering into any settlement of a Third Party Claim. Notwithstanding the foregoing, the Indemnifying Party shall not be entitled to enter into or approve any settlement of a Third Party Claim without the consent of the Indemnified Party (which may be withheld in its sole discretion), if the settlement (a) does not expressly unconditionally release all applicable Indemnified Parties and their Affiliates from all Liabilities with respect to such Third Party Claim or (b) imposes injunctive or other equitable relief against the Indemnified Party or any of its Affiliates, (c) involves any admission of criminal or similar liability, or (d) involves any monetary damages that may not be fully covered by the Indemnifying Party. In the event that the Indemnifying Party fails to assume the defense of the Third Party Claim in accordance with this Section 7.3, (a) the Indemnified Party may defend against the Third Party Claim in any manner it reasonably may deem appropriate, and (b) the Indemnifying Party will remain responsible for any Losses of the Indemnified Party as a result of such Third Party Claim. In circumstances where the Indemnifying Party is controlling the defense of a Third Party Claim in accordance with this Section 7.3, the Indemnified Party shall be entitled to participate in the defense of any Third Party Claim and to employ separate counsel of its choice for such purpose, in which case the fees and expenses of such separate counsel shall be borne by such Indemnified Party. Notwithstanding anything herein to the contrary, in circumstances where there is a conflict of interest that would reasonably make it inappropriate under applicable standards of professional conduct to have common counsel for the Indemnifying Party and the Indemnified Party, the Indemnified Party shall be entitled to employ separate counsel, that is reasonably acceptable to the Indemnifying Party, and the Indemnifying Party shall pay the reasonable fees and expenses of such separate counsel. Each Party shall cooperate, and cause their respective Affiliates to cooperate in all reasonable respects, in the defense or prosecution of any Third Party Claim and shall furnish or cause to be furnished such records, information and testimony, and attend such conferences, discovery proceedings, hearings, trials or appeals, as may be reasonably requested in connection therewith.
7.4    Insurance. Each Party shall maintain insurance, including product liability insurance, with respect to its activities under this Agreement regarding Products in such amount as such Party customarily maintains with respect to similar activities for its other products. Each Party shall maintain such insurance for so long as it continues its activities under this Agreement, and thereafter for so long as such Party customarily maintains insurance for itself covering similar activities for its other products. Notwithstanding the foregoing, the Parties agree that during such time that Licensee is an Affiliate of Protiva, Licensee shall have satisfied its obligations under this Section 7.4 provided it is covered by Protiva’s existing insurance policies.

23




ARTICLE VIII –    TERM AND TERMINATION
8.1    Term    . The term of this Agreement (the “Term”) shall begin on the Original Effective Date and, unless terminated earlier as provided herein, shall continue in perpetuity.
8.2    Termination for Material Breach    . In the event of a material breach of this Agreement by Licensee, Protiva may provide notice to Licensee setting forth the nature of the breach and a description of the facts underlying the breach sufficient to identify the breach. If Licensee has not cured such breach or proposed a reasonably satisfactory plan to cure or otherwise remedy such breach within ninety (90) days from the date of receipt of such notice of breach, Protiva may provide a notice of termination to Licensee and this Agreement shall terminate ninety (90) days after such notice of termination unless the breach is cured to the reasonable satisfaction of Protiva or unless Licensee has begun to implement a reasonably satisfactory plan to cure or otherwise remedy such breach within ninety (90) days from the receipt of such notice of termination. Notwithstanding the foregoing, or any termination of Licensee’s license pursuant to Section 8.4 below, with respect to any sublicense entered into by Licensee for which the Sublicensee is not the cause of the material breach that resulted in the termination of this Agreement, then upon the assignment to Protiva of all rights of Licensee under such sublicense, Protiva shall assume those obligations of Licensee to such Sublicensee under such sublicense that are within the scope of Protiva’s obligations to Licensee under this Agreement; all other obligations to the Sublicensee under such sublicense, and all liabilities of Licensee to such Sublicensee, shall remain the sole and exclusive obligations and liabilities of Protiva, and nothing in this Section 8.2 shall be deemed to expand, increase, or otherwise modify Protiva’s obligations or liabilities under this Agreement.
8.3    Challenges of Protiva’s Patents. If Licensee or any of its Affiliates shall (a) commence or participate in any action or proceeding (including any patent opposition or re-examination proceeding), or otherwise assert in writing any claim, challenging or denying the validity of any of the Protiva Background Patents or Protiva Project Patents or any claim thereof or (b) actively assist any other Person in bringing or prosecuting any action or proceeding (including any patent opposition or re-examination proceeding) challenging or denying the validity of such Patents or any claim thereof, Protiva will have the right to give notice to Licensee (which notice must be given, if at all, within ninety (90) days after Arbutus’s CEO first learns of the foregoing) that the licenses granted by Protiva to such Patent will terminate in ninety (90) days following such notice, and, unless Licensee and/or its Affiliate, as applicable, withdraws or causes to be withdrawn all such challenge(s) within such ninety-day period, such licenses will so terminate.
8.4    Rights in Bankruptcy. Each Party (the “Insolvent Party”) shall promptly notify the other Party (the “Solvent Party”) in writing upon the initiation of any proceeding in bankruptcy, reorganization, dissolution, liquidation or arrangement for the appointment of a receiver or trustee to take possession of the assets of the Insolvent Party or similar proceeding under the law for release of creditors by or against the Insolvent Party or if the Insolvent Party shall make a general assignment for the benefit of its creditors. To the extent permitted by Applicable Law, if the applicable circumstances described above shall have continued for ninety (90) days undismissed, unstayed, unbonded and undischarged, the Solvent Party may terminate this Agreement upon written notice to the Insolvent Party at any time. If Protiva is the Insolvent Party, the rights and remedies granted

24




to Licensee (as the Solvent Party) pursuant to this Section 8.4 shall be in addition to, and not in lieu of, Licensee’s rights and remedies under Section 2.4 above.
8.5    Consequences of Termination; Survival.
(a)    In the event this Agreement is properly terminated in accordance with its terms, then except as provided in the Protiva-Monsanto Services Agreement, Licensee’s rights and licenses under the Protiva Intellectual Property shall terminate upon the effective date of such termination. Termination of this Agreement shall not relieve the Parties of any obligation accruing prior to or upon such expiration or termination and the provisions of ARTICLE I – (Definitions), ARTICLE VI – (Confidential Information), ARTICLE VII – (Indemnification), and ARTICLE IX – (Miscellaneous) shall survive any expiration or termination of this Agreement.
(b)    Notwithstanding anything to the contrary contained in this Agreement, if it is determined that Protiva has breached its representation and warranty in Section 9.1(b)(iii), Licensee’s sole and exclusive remedy shall be to require Arbutus or its Affiliate, as applicable, to grant to Licensee a license under its Patents or Know-How for all purposes in the Agricultural Field and such Patents and/or Know-How shall thereafter be included within Protiva Intellectual Property for all purpose of this Agreement; provided, however, that the foregoing shall not be deemed to limit, eliminate or otherwise modify Protiva’s obligations under Section 7.1 to indemnify any Licensee Indemnitee against or hold any Licensee Indemnitee harmless in respect of any Losses actually incurred or suffered by a Licensee Indemnitee arising out of or in connection with any claim, suit, demand, investigation or proceeding brought by UBC or any other Third Party based on any breach of any representation, warranty or covenant by Protiva under this Agreement, including Section 9.1(b)(vi), even if or to the extent such Losses may also arise out Protiva’s breach of Section 9.1(b)(iii). Furthermore, omission from the Technology Transfer Compound List of any Compound or Formulation that was provided or created by Protiva or its Affiliate in connection with the Research Program shall not be deemed to limit or eliminate Licensee’s rights under the second sentence of Section 2.1 with respect to such Compound or Formulation.
8.6    Remedies. The Parties acknowledge and agree that, in the event of a breach or a threatened breach by either Party of this Agreement for which it will have no adequate remedy at law, the other Party may suffer irreparable damage and, accordingly, shall be entitled to injunctive and other equitable remedies to prevent or restrain such breach or threatened breach, in addition to any other remedy they might have at law or at equity. In the event of a breach or threatened breach by a Party of any such provision, the other Party shall be authorized and entitled to obtain from any court of competent jurisdiction injunctive relief, whether preliminary or permanent, arising from such breach, which rights shall be cumulative and in addition to any other rights or remedies to which the other Party may be entitled in law or equity.

Exhibit
Exhibit 10.81


FIRST AMENDMENT
TO
PROTIVA-MONSANTO SERVICES AGREEMENT

THIS FIRST AMENDMENT TO THE PROTIVA-MONSANTO SERVICES AGREEMENT (this “Amendment”) is made and entered into as of March 4, 2016, (the “Effective Date”) by and among Protiva Biotherapeutics, Inc., a British Columbia corporation (“Protiva”) and a wholly-owned subsidiary of Arbutus Biopharma Corporation, formerly Tekmira Pharmaceutcals Corporation (“Arbutus”), Protiva Agricultural Development Company Inc. (“PadCo”), a British Columbia corporation and a wholly-owned subsidiary of Protiva (the “Company”), and Monsanto Company, a Delaware corporation (“Monsanto”).

WHEREAS, Protiva, the Company and Monsanto entered into that certain Protiva-Monsanto Services Agreement on January 12, 2014 (the “Agreement”), and, contemporaneously with the execution of the Agreement: (a) Protiva, Arbutus, PadCo and Monsanto Canada entered into the Option Agreement and (b) PadCo, Protiva and Tekmira entered into the PadCo-Protiva License and Services Agreement;
WHEREAS, contemporaneously with the execution of this Amendment and as of the Effective Date: (a) the parties to the PadCo-Protiva License and Services Agreement are amending and restating the PadCo-Protiva License and Services Agreement, (b) the parties to the Option Agreement are amending and restating the Option Agreement, (c) Monsanto is exercising the Call Option to acquire all of the outstanding capital stock of PadCo, and (d) Closing is occurring;
WHEREAS, Protiva, the Company and Monsanto desire to amend the Agreement, effective as of the Effective Date, as set forth herein; and
NOW THEREFORE, in consideration of the representations, warranties, covenants and agreements contained herein, and for other valuable consideration, the receipt and adequacy of which is hereby acknowledged, the parties mutually agree to amend and modify the Agreement as follows:

1.All capitalized terms used in this Amendment, unless otherwise defined, shall have the meanings ascribed to such terms in the Agreement. In addition, the following terms shall have the following meanings for purposes of this Amendment:
(a)    “Monsanto New Improvement” means an invention that is (i) Monsanto New Intellectual Property, (ii) claimed in an issued patent owned by Monsanto and having a priority date that is on or after the Effective Date, and (iii) the practice of which, if practiced at the time of said

1

Exhibit 10.81


priority date, would be covered by at least one Valid Claim of a Patent that is a Protiva Background Patent or Protiva Project Patent.
(b)    “Monsanto New Intellectual Property” means all inventions that are conceived by Monsanto Personnel on or after the Effective Date and that are covered by at least one Valid Claim of a Patent. For the avoidance of doubt inventions that were conceived by Monsanto Personnel in the conduct of activities under the Research Program and that are not Joint Project Intellectual Property are Monsanto Project Intellectual Property and not Monsanto New Intellectual Property.
2.The Parties acknowledge and agree that, as of the Effective Date, Monsanto Canada is exercising the Call Option prior to completion of Phase C (as such term is defined in the Research Program). Monsanto hereby elects to terminate research under the Research Plan as of the Effective Date and, therefore, the Parties acknowledge and agree that, on and as of the Effective Date, the Term of the Agreement shall be deemed to expire.
3.The following new subsection (c) is hereby added to Section 4.2 of the Agreement:
“(c)    an irrevocable, worldwide, perpetual (subject to Sections 8.3 and 8.4), royalty-free, transferrable (subject to Section 9.1 below) license, with right to sublicense (subject to Section 4.3 below), in and to any Monsanto New Improvements for all purposes in the Protiva Field, which license shall be exclusive, other than in respect of any Monsanto New Improvements that Monsanto is obligated to license to a third party pursuant to any agreement in existence as of the Effective Date, in which case such license shall be non-exclusive.
4.References to “Monsanto Improvements” in Sections 4.1, 4.3, 4.7, 4.9, 4.10, 6.2, and 8.3(ii) of the Agreement shall be deemed to also refer to and include Monsanto New Improvements.
5.References to “Monsanto Project Intellectual Property” in Sections 4.1, 4.4, and 4.5 of the Agreement shall be deemed to also refer to and include Monsanto New Intellectual Property.
6.In all other respects, the terms, conditions, and covenants of the Agreement shall remain unchanged and any rights that either of the Parties may have under the Agreement shall remain in full force and effect.
7.This Amendment may be executed in two or more counterparts, each of which will be deemed an original and all of which together will constitute one and the same instrument. Each shall be considered signed when the signature of a Party is delivered by facsimile, electronic signature or electronic (email) transmission to the other Parties, when it is delivered in a manner that reasonably identifies the signatory as the Party named. Such electronic signatures shall be

2

Exhibit 10.81


treated in all respects as having the same effect as an original signature. If requested by any Party, documents bearing an original signature may be subsequently and promptly submitted to replace copies bearing electronic signatures. By signing this Amendment the representatives of each Party thereby represent that such Person is duly authorized by the Party in question to execute this Amendment on behalf of such Party and that each respective Party agrees to be bound by the provisions thereof. The Parties to this document agree that a copy of the original signature (including an electronic copy) may be used for any and all purposes for which the original signature may have been used.
