This FDA-approved indication for Vascepa, known as theMARINE indication, is based primarily on the successful results from the MARINE study of Vascepa in this approved patient population. In considering thisapproval, FDA also reviewed the successful results from our study of Vascepa in patients with high triglyceride levels (TG 200 mg/dL and <500 mg/dL)who are also on statin therapy for elevated low-density lipoprotein cholesterol, or LDL-C, levels which condition we refer to as mixed dyslipidemia orpersistently high triglycerides. This study is known as the ANCHOR study. Safety data from both the MARINE and ANCHOR studies are reflected inFDA-approved labeling for Vascepa. In January 2013, we began selling and marketing Vascepa in the United States based on the FDA-approved MARINEindication. In August 2015, we also began communicating promotional information beyond the MARINE indication to healthcare professionals in theUnited States based on the federal court declaration described below. In March 2016, we reached agreement with the FDA and U.S. government under whichthey agreed to be bound by the terms of the August 2015 judicial declaration. Vascepa is available in the United States by prescription only.We sell Vascepa principally to a limited number of major wholesalers, as well as selected regional wholesalers and specialty pharmacy providers, orcollectively, our Distributors or our customers, that in turn resell Vascepa to retail pharmacies for subsequent resale to patients and healthcare providers. Wemarket Vascepa in the United States through our direct sales force of approximately 150 sales professionals, including sales representatives and theirmanagers. In March 2014, we entered into a co-promotion agreement in the United States with Kowa Pharmaceuticals America, Inc. under which no less than250 Kowa Pharmaceuticals America, Inc. sales representatives began to devote a substantial portion of their time to promoting Vascepa starting in May 2014.In February 2015, we entered into an exclusive agreement with Eddingpharm (Asia) Macao Commercial Offshore Limited, or Eddingpharm, to developand commercialize Vascepa capsules in Mainland China, Hong Kong, Macau and Taiwan, or the China Territory. In March 2016, we entered into anagreement with Biologix 2®Table of ContentsFZCo, or Biologix, to register and commercialize Vascepa in countries within the Middle East and North Africa. We continue to assess other partnershipopportunities for licensing Vascepa to partners outside of the United States.Triglycerides are the main constituent of body fat in humans. Hypertriglyceridemia refers to a condition in which patients have high levels oftriglycerides in the bloodstream. It is estimated that over 70 million adults in the United States have elevated triglyceride levels (TG 150 mg/dL),approximately 40 million adults in the United States have high triglyceride levels (TG 200 mg/dL), and approximately 4.0 million people in the UnitedStates have severely high triglyceride levels (TG 500 mg/dL), commonly known as very high triglyceride levels. Many patients with high triglyceridelevels also have diabetes and other lipid level abnormalities such as high cholesterol. The patient condition of having more than one lipid level abnormalityis referred to as mixed dyslipidemia. According to The American Heart Association Scientific Statement on Triglycerides and Cardiovascular Disease(2011), triglycerides provide important information as a marker associated with the risk for heart disease and stroke, especially when an individual also haslow high-density lipoprotein cholesterol, or HDL-C (often referred to as “good” cholesterol), and elevated levels of LDL-C (often referred to as “bad”cholesterol). Guidelines for the management of very high triglyceride levels suggest that reducing triglyceride levels is the primary goal in patients to reducethe risk of acute pancreatitis. The effect of Vascepa on cardiovascular mortality and morbidity, or the risk for pancreatitis, in patients withhypertriglyceridemia has not been determined.We are currently focused on completing the ongoing REDUCE-IT (Reduction of Cardiovascular Events with EPA—Intervention Trial) cardiovascularoutcomes study of Vascepa, which we started in December 2011. REDUCE-IT, a multinational, prospective, randomized, double-blind, placebo-controlledstudy, is the first prospective cardiovascular outcomes study of any drug in a population of patients who, despite stable statin therapy, have elevatedtriglyceride levels. Based on the results of REDUCE-IT, we plan to seek additional indicated uses for Vascepa. In REDUCE-IT, cardiovascular event rates forpatients on stable statin therapy plus 4 grams per day of Vascepa will be compared to cardiovascular event rates for patients on stable statin therapy plusplacebo. In 2016, we completed patient enrollment and randomization of 8,175 individual patients into the REDUCE-IT study, exceeding the 8,000 patientstargeted for the trial.The REDUCE-IT study is designed to be completed after reaching 1,612 aggregate primary cardiovascular events. Based on projected event rates, weestimate the onset of the target aggregate number of cardiovascular events to be reached near the end of 2017 with study results then expected to be availableand published in 2018. In addition, since its inception in 2011, our REDUCE-IT special protocol assessment (SPA) agreement with the FDA has provided forperiodic safety reviews and an interim efficacy and safety analysis by the study’s independent data monitoring committee (DMC) at approximately 60% ofthe target aggregate number of primary cardiovascular events. In August 2016, we announced an amendment to our REDUCE-IT SPA agreement with FDAthat reaffirmed FDA concurrence on key elements of the study, defined details of the statistical analysis plan for the study, expanded to greater than 30 thepre-specified secondary and tertiary endpoints in the study, and added a second interim efficacy and safety analysis by the DMC at approximately 80% of thetarget aggregate number of primary cardiovascular events. The periodic safety reviews and interim efficacy and safety analyses are conducted confidentiallyby the study’s DMC. We remain blinded to all data from the study. Since patient enrollment commenced in 2011, more than 26,000 patient years of studyexperience have been accumulated in the REDUCE-IT study. Following each periodic review of safety data to date, the DMC has communicated to us that weshould continue the study as planned.In March 2016, we announced that the onset of approximately 60% of the target aggregate number of primary cardiovascular events had triggeredpreparation for the first pre-specified interim analysis of efficacy and safety results. Such analysis included the first review of unblinded efficacy data by theindependent DMC. The DMC completed its review of the interim analysis in September 2016 and, consistent with previously stated expectations,recommended that the trial continue as planned without modification. The second planned interim analysis of efficacy results will be triggered by the onsetof approximately 80% of the target aggregate number of 3Table of Contentsprimary cardiovascular events in the study. Based on historical event rates, we anticipate that the onset of approximately 80% of events will occur in the firsthalf of 2017, with the second pre-specified interim efficacy analysis by the DMC expected in or about the third quarter of 2017. The interim efficacy analysiswill be accompanied by an interim safety analysis by the DMC. As is typical, the statistical threshold for defining overwhelming efficacy on the primaryendpoint at interim analyses is considerably higher than the threshold for defining statistical significance at the end of the study. In addition, we haverequested the DMC to not recommend stopping the study early based only upon the achievement of statistical significance for the primary endpoint, but toensure that supportive trends of benefit are also consistently observed in certain secondary endpoints and subpopulations before recommending that thestudy be stopped early for overwhelming efficacy. This is the same approach we asked the DMC to employ in connection with the REDUCE-IT study 60%interim analysis. It is our expectation that the 80% interim analysis will also result in a recommendation by the DMC to continue the trial.In the successful Phase 3 MARINE and ANCHOR clinical trials, Vascepa was studied at a daily dose of 2 grams and 4 grams. We sought approval ofVascepa at the more efficacious 4-gram dose for use in each patient population. These trials demonstrated favorable results in their respective patientpopulations, particularly with the 4-gram dose of Vascepa, in reducing triglyceride levels without increasing LDL-C levels in the MARINE trial and with astatistically significant decrease in LDL-C levels in the ANCHOR trial, in each case, relative to placebo. These trials also showed favorable results,particularly with the 4-gram dose of Vascepa, in other important lipid and inflammation biomarkers, including apolipoprotein B (apo B), non-high-densitylipoprotein cholesterol (non-HDL-C), total-cholesterol (TC), very low-density lipoprotein cholesterol (VLDL-C), lipoprotein-associated phospholipase A2(Lp-PLA2), and high sensitivity C-reactive protein (hs-CRP). In these trials, the most commonly reported adverse reaction (incidence >2% and greater thanplacebo) in Vascepa-treated patients was arthralgia (joint pain) (2.3% for Vascepa vs. 1.0% for placebo).In April 2015, we received a Complete Response Letter, or CRL, from the FDA in response to our supplemental new drug application, or sNDA, thatsought approval of Vascepa for use in patients with mixed dyslipidemia, based on the successful ANCHOR study. The CRL followed an October 2013rescission by the FDA of a special protocol assessment, or SPA, agreement and three failed attempts by us to appeal that rescission at FDA. The FDA hasacknowledged the success of the ANCHOR study, which met all primary and secondary endpoints. However, FDA determined that there were insufficient datato conclude that drug-induced changes in serum triglycerides could be recognized by the FDA as a valid surrogate for reducing cardiovascular risk in theANCHOR population for the purpose of regulatory approval of a drug targeted at a triglyceride-lowering indication in this population. The FDA hasacknowledged that the standard of proof required by the FDA for approval of a new drug indication is higher than that generally used to inform patienttreatment guidelines and that used by physicians in clinical practice. The FDA did not determine that the drug-induced effects of Vascepa, which go beyondtriglyceride-lowering, would not actually reduce cardiovascular risk in this population and the FDA has encouraged us to complete the REDUCE-IToutcomes study. Based on our communications with the FDA, we expect that final positive results from the REDUCE-IT outcomes study will be required forlabel expansion for Vascepa.In May 2015, we and a group of independent physicians filed a lawsuit in federal court to permit us to promote to healthcare professionals the use ofVascepa in patients with mixed dyslipidemia so long as the promotion is truthful and non-misleading. This use reflects recognized medical practice but is notcovered by current FDA-approved labeling for the drug. Historically, FDA has considered promotion of drug uses not covered by FDA approved labelling tobe illegal off-label promotion, even if such promotion is truthful and non-misleading. In August 2015, we were granted preliminary relief in the form of adeclaratory judgment in this lawsuit. The court declaration permits us to promote to healthcare professionals the FDA-reviewed and agreed effects of Vascepademonstrated in the ANCHOR clinical trial and presentation of the current state of scientific research related to the potential of Vascepa to reduce the risk ofcardiovascular disease including through use of peer-reviewed scientific publications of available data. In August 2015, we began to communicatepromotional information beyond the MARINE indication to healthcare professionals in the United States as permitted by this 4Table of Contentscourt declaration and in March 2016, the parties obtained court approval of negotiated settlement terms under which the FDA and the U.S. governmentagreed to be bound by the court’s conclusions from the August 2015 declaration that we may engage in truthful and non-misleading speech promoting theoff-label use of Vascepa and that certain statements and disclosures that we proposed to make to healthcare professionals were truthful and non-misleading.While we believe we are now permitted under applicable law to more broadly promote Vascepa, the FDA-approved labeling for Vascepa did not change as aresult of this litigation and settlement, and neither government nor other third-party coverage or reimbursement to pay for the off-label use of Vascepapromoted under the court declaration was required.Commercialization—United StatesWe commenced the commercial launch of 1-gram size Vascepa capsules in the United States in January 2013. We commenced sales and shipments ofVascepa at that time to our network of U.S.-based wholesalers. We currently market Vascepa in the United States through our direct sales force ofapproximately 150 sales professionals, including sales representatives and their managers. Commencing in May 2014, in addition to Vascepa promotion byour sales representatives, no less than 250 Kowa Pharmaceuticals America, Inc. sales representatives began devoting a substantial portion of their time topromoting Vascepa. We also employ various marketing personnel to support our commercialization of Vascepa. In October 2016, in addition to the original1-gram capsule size for Vascepa, we introduced a smaller 0.5-gram capsule size, the first and only 0.5-gram prescription omega-3 alternative available on themarket, for the subset of patients who prefer a smaller capsule. The FDA-approved dosing for Vascepa continues to be 4 grams per day, and we expect that themajority of patients taking Vascepa will continue to be prescribed the 1-gram size Vascepa capsule. We also expect that the majority of new patients will beprescribed the 1-gram size Vascepa capsule.Under our co-promotion agreement with Kowa Pharmaceuticals America, Inc., both parties have agreed to use commercially reasonable efforts topromote, detail and optimize sales of Vascepa in the United States and have agreed to specific performance requirements detailed in the related agreement.The performance requirements include a negotiated minimum number of sales details to be delivered by each party in the first and second position, the use ofa negotiated number of minimum sales representatives from each party, including no less than 250 Kowa Pharmaceuticals America, Inc. sales representativesand the achievement of minimum levels of Vascepa revenue in 2015 and beyond. First position refers to when a sales representative’s primary purpose indetailing is related to Vascepa, while second position refers to when a sales representative’s primary purpose in detailing is to promote another product, butthey also devote time in the same sales call to promote Vascepa. Kowa Pharmaceuticals America, Inc. has also agreed to continue to bear the costs incurred forits sales force associated with the commercialization of Vascepa and to pay for certain incremental costs associated with the use of its sales force, such assample costs and costs for promotional and marketing materials. We will continue to recognize all revenue from sales of Vascepa. In exchange for KowaPharmaceuticals America, Inc.’s co-promotional services, Kowa Pharmaceuticals America, Inc. is entitled to a quarterly co-promotion fee based on apercentage of aggregate Vascepa gross margin that increases during the term. The percentage of aggregate Vascepa gross margin earned by KowaPharmaceuticals America, Inc. was fifteen percent (15%) in 2015, was nineteen percent (19%) in 2016, and is scheduled to increase to low twenty percentlevels in 2017 and 2018, subject to certain adjustments. The term of this co-promotion agreement expires on December 31, 2018, following which ouragreement with Kowa Pharmaceuticals America, Inc. provides for up to three years of tail royalties equal to declining percentages of the co-promotion feeearned prior to agreement expiration.Based on monthly compilations of data provided by a third party, Symphony Health Solutions, the estimated number of normalized total Vascepaprescriptions for the three months ended December 31, 2016 was approximately 286,000 compared to 260,000, 230,000, 201,000, and 191,000 in the threemonths ended September 30, 2016, June 30, 2016, March 31, 2016, and December 31, 2015, respectively. According to data from another third party, IMSHealth, the estimated number of normalized total Vascepa prescriptions for the three months ended December 31, 2016 was approximately 312,000 comparedto 274,000, 249,000, 216,000, and 203,000 in the three months ended September 30, 2016, June 30, 2016, March 31, 2016, and December 31, 2015, 5Table of Contentsrespectively. Normalized total prescriptions represent the estimated total number of Vascepa prescriptions shipped to patients, calculated on a normalizedbasis (i.e., one month’s supply, or total capsules shipped multiplied by the number of grams per capsule divided by 120 grams). Inventory levels atwholesalers tend to fluctuate based on seasonal factors, prescription trends and other factors. During 2016, predominantly in the second quarter, wholesalerinventory levels increased based on estimated days of inventory on hand. In addition, regional stocking of Vascepa expanded at certain retail pharmacies,likely due to higher volume sales of Vascepa.The data reported above is based on information made available to us from third-party resources and may be subject to adjustment and may overstate orunderstate actual prescriptions. Timing of shipments to wholesalers, as used for revenue recognition purposes, and timing of prescriptions as estimated bythese third parties may differ from period to period. Although we believe these data are prepared on a period-to-period basis in a manner that is generallyconsistent and that such results can be generally indicative of current prescription trends, these data are based on estimates and should not be relied upon asdefinitive. While we expect to be able to grow Vascepa revenues over time, no guidance should be inferred from the operating metrics described above. Wealso anticipate that such sales growth will be inconsistent from period to period. We believe that investors should view the above-referenced operatingmetrics with caution, as data for this limited period may not be representative of a trend consistent with the results presented or otherwise predictive of futureresults. Seasonal fluctuations in pharmaceutical sales, for example, may affect future prescription trends of Vascepa, as could changes in prescriber sentiment,quarterly changes in Distributor purchases, and other factors. These fluctuations from multiple variables make it difficult to predict quarterly prescriptiontrends and product revenues on a consistent basis. We believe investors should consider our results over several quarters, or longer, before making anassessment about potential future performance.The commercialization of pharmaceutical products is a complex undertaking, and our ability to effectively and profitably commercialize Vascepa willdepend in part on our ability to generate market demand for Vascepa through education, marketing and sales activities, our ability to achieve marketacceptance of Vascepa, our ability to generate product revenue and our ability to receive adequate levels of reimbursement from third-party payers. See “RiskFactors—Risks Related to the Commercialization and Development of Vascepa.”In August 2015, we and our co-promotion partner began communicating promotional information beyond MARINE clinical trial data to targetedhealthcare professionals. Such qualified communications are being made pursuant to the August 7, 2015 federal district court declaration and related March2016 settlement allowing truthful and non-misleading promotion of the FDA-reviewed and agreed effects of Vascepa demonstrated in the ANCHOR clinicaltrial and presentation of the current state of scientific research related to the potential of Vascepa to reduce the risk of cardiovascular disease includingthrough use of peer-reviewed scientific publications of available data.Commercialization—Outside the United StatesIn February 2015, we announced an exclusive agreement with Eddingpharm to develop and commercialize Vascepa capsules in what we refer to as theChina Territory, consisting of the territories of Mainland China, Hong Kong, Macau and Taiwan, for uses that are currently commercialized and underdevelopment by us in the United States based on the MARINE, ANCHOR and ongoing REDUCE-IT clinical trials of Vascepa.Under the agreement, Eddingpharm is responsible for development and commercialization activities in the China Territory and associated expenses.We will provide development assistance and be responsible for supplying the product. Terms of the agreement include up-front and milestone payments to usof up to $169.0 million, including a non-refundable $15.0 million up-front payment received at closing, a non-refundable milestone payment of $1.0 millionreceived upon successful submission of a clinical trial application with respect to the MARINE indication for Vascepa to the Chinese regulatory authority inMarch 2016, and future regulatory and sales-based milestone payments of up to an additional $153.0 million. The regulatory milestone events relate to thesubmission and approval of certain applications to the applicable regulatory authority, such as a clinical 6Table of Contentstrial application, clinical trial exemption, or import drug license application. The amounts to be received upon achievement of the regulatory milestoneevents relate to the submission and approval for three indications, and range from $1.0 million to $15.0 million for a total of $33.0 million. The sales-basedmilestone events occur when annual aggregate net sales of Vascepa in the territory equals or exceeds certain specified thresholds, and range from $5.0 millionto $50.0 million for a total of $120.0 million. Eddingpharm will also pay us tiered double-digit percentage royalties on net sales of Vascepa in the ChinaTerritory escalating to the high teens. We will supply finished product to Eddingpharm under negotiated terms.In March 2016, we entered into an agreement with Biologix to register and commercialize Vascepa in several Middle Eastern and North Africancountries. Under the terms of the distribution agreement, we granted to Biologix a non-exclusive license to use our trademarks in connection with theimportation, distribution, promotion, marketing and sale of Vascepa in the Middle East and North Africa territory. Upon closing of the agreement, wereceived a non-refundable up-front payment, which will be recognized as revenue over 10 years commencing upon first marketing approval of Vascepa in theterritory. We are entitled to receive payments based on product sales at an agreed-upon transfer price, which represents a percentage of gross selling price,subject to a minimum floor price.We continue to assess other partnership opportunities for licensing Vascepa to partners outside of the United States.Research and DevelopmentREDUCE-IT is the first prospective cardiovascular outcomes study of any drug in a population of patients who, despite stable statin therapy, haveelevated triglyceride levels. REDUCE-IT is a multinational, prospective, randomized, double-blind, placebo-controlled study designed to assess thecumulative effect on the rate of cardiovascular events for patients treated with Vascepa as an add-on to statin therapy compared to the corresponding rate ofcardiovascular events for patients treated with placebo on top of statin therapy. REDUCE-IT is not designed to demonstrate that lowering triglycerides alonein the study population is sufficient to lower the rate of major adverse cardiovascular events compared to placebo. Rather, it is designed to demonstrate thatclinical effects of Vascepa, including its impact on triglyceride lowering, is effective in lowering the rate of major adverse cardiovascular events compared toplacebo in patients who despite statin therapy have risk factors for cardiovascular disease, including elevated triglyceride levels. Based on the results ofREDUCE-IT, we may seek additional indications for Vascepa beyond the indications studied in the ANCHOR or MARINE trials.In 2016, we completed patient enrollment and randomization of 8,175 individual patients into the REDUCE-IT study, exceeding the 8,000 patientstargeted for the trial.Completion of the REDUCE-IT study is designed to occur after reaching an aggregate number of cardiovascular events. Based on projected event rates,we estimate the onset of the target aggregate number of cardiovascular events to be reached near the end of 2017 with study results then expected to beavailable in 2018. In addition, since its inception in 2011, our REDUCE-IT SPA agreement with the FDA has provided for periodic safety reviews and aninterim efficacy and safety analysis by the independent DMC at approximately 60% of the target aggregate number of primary cardiovascular events. InAugust 2016, we announced an amendment to our REDUCE-IT SPA agreement with FDA that reaffirmed FDA concurrence on key elements of the study,defined details of the statistical analysis plan for the study, expanded to greater than 30 the pre-specified secondary and tertiary endpoints in the study, andadded a second interim efficacy and safety analysis by the DMC at approximately 80% of the target aggregate number of primary cardiovascular events.In March 2016, we announced that the onset of approximately 60% of the target aggregate number of primary cardiovascular events had triggeredpreparation for the first pre-specified interim analysis of efficacy and safety results. Such analysis included the first review of unblinded efficacy data by theindependent DMC. The 7Table of ContentsDMC completed its review of the interim analysis in September 2016 and, consistent with previously stated expectations, recommended that the trialcontinue as planned without modification. The second planned interim analysis of efficacy results will be triggered by the onset of approximately 80% of thetarget aggregate number of primary cardiovascular events in the study. Based on historical event rates, we anticipate that the onset of approximately 80% ofevents will occur in the first half of 2017, with the second pre-specified interim efficacy analysis by the DMC expected in or about the third quarter of 2017.The interim efficacy analysis will be accompanied by an interim safety analysis by the DMC. As is typical, the statistical threshold for definingoverwhelming efficacy on the primary endpoint at interim analyses is considerably higher than the threshold for defining statistical significance at the end ofthe study. In addition, we have requested the DMC to not recommend stopping the study early based only upon the achievement of statistical significance forthe primary endpoint, but to ensure that supportive trends of benefit are also consistently observed in certain secondary endpoints and subpopulations beforerecommending that the study be stopped early for overwhelming efficacy. This is the same approach we asked the DMC to employ in connection with theREDUCE-IT study 60% interim analysis. It is our expectation that the 80% interim analysis will also result in a recommendation by the DMC to continue thetrial. By design, it is most common for cardiovascular outcomes studies not to be stopped upon an interim look. We remain blinded to all data from the study.Unless overwhelming efficacy and safety is declared by the DMC at an interim look or the study is halted due to a patient safety concern, Amarin personnelwill remain blinded to the efficacy and safety data from the REDUCE-IT study until the study is complete.Since patient enrollment commenced in 2011, more than 26,000 patient years of study experience have been accumulated in REDUCE-IT. The DMChas reviewed unblinded safety data on a quarterly basis since 2013 and, after each such review of unblinded safety data to date, the DMC has recommendedto us that the study be continued as planned.Our scientific rationale for the REDUCE-IT study is supported by (i) epidemiological data that suggests elevated triglyceride levels correlate withincreased cardiovascular disease risk, (ii) genetic data that suggests triglyceride and/or triglyceride-rich lipoproteins (as well as low-density lipoproteincholesterol (LDL cholesterol), known as bad cholesterol) are independently in the causal pathway for cardiovascular disease and (iii) clinical data thatsuggest substantial triglyceride reduction in patients with elevated baseline triglyceride levels correlates with reduced cardiovascular risk. Our scientificrationale for the REDUCE-IT study is also supported by research on the putative cardioprotective effects of EPA as presented in scientific literature. It ispossible that the effects of EPA may be due not to a single mode of action, such as triglyceride lowering, but rather to multiple mechanisms working together.Studies in the scientific literature explore potentially beneficial effects of EPA on multiple atherosclerosis processes, including endothelial function,oxidative stress, foam cell formation, inflammation/cytokines, plaque formation/progression, platelet aggregation, thrombus formation, and plaque rupture.The REDUCE-IT study is needed to determine the clinical benefit, if any, of EPA therapy in statin-treated patients with elevated triglyceride levels.Commercial SupplyPrior to 2015, all of our active pharmaceutical ingredient, or API, that has been utilized in product sold was manufactured by two suppliers: NisshinPharma, Inc., or Nisshin, and Chemport, Inc., or Chemport. A significant portion of such API was purchased from Nisshin at a price that was higher thanprojected future average API costs. During 2015, we began purchasing API from a third supplier, Finorga SAS, or Novasep. The amount of supply we seek topurchase in future periods will depend on the level of growth of Vascepa revenues and minimum purchase commitments with certain suppliers. While ourcurrent supply chain is scalable, we continue efforts to expand, diversify and further enhance it.Financial PositionWe believe that our cash and cash equivalents balance of $98.3 million as of December 31, 2016 will be sufficient to fund our projected operationsthrough the results of the REDUCE-IT study, which we anticipate will 8Table of Contentsbe available mid-2018. Depending on the level of cash generated from operations, additional capital may be required to sustain operations, fund debtobligations or expand promotion of Vascepa as contemplated following anticipated successful results of the REDUCE-IT study. We anticipate that quarterlynet cash outflows in future periods will be variable.Lipid Disorders and Cardiovascular DiseaseHeart attacks, strokes and other cardiovascular events represent the leading cause of death and disability among men and women in western societies.According to the Heart Disease and Stroke Statistics—2017 Update from the American Heart Association, more than 1 out of every 3 adults in the UnitedStates (approximately 92 million) currently lives with one or more types of cardiovascular disease; an estimated 1,000,000 new or recurrent coronary eventsand 795,000 new or recurrent strokes occur each year; an estimated 29 million adults 20 years of age have high total serum cholesterol levels (240mg/dL), and an estimated 71 million adults 20 years of age have borderline high or high low-density lipoprotein (“bad”) cholesterol, or LDL-C, levels(130 mg/dL).In addition to cholesterol, lipoproteins such as LDL also carry fats in the form of triglycerides. Hypertriglyceridemia refers to a condition in whichpatients have high levels of triglycerides in the bloodstream and has been recognized as an independent risk factor for cardiovascular disease. Triglyceridelevels provide important information as a marker associated with the risk for heart disease and stroke, especially when an individual also has low high densitylipoprotein cholesterol (HDL-C; often called “good” cholesterol) and elevated levels of LDL-C. The effect of Vascepa on cardiovascular mortality andmorbidity in patients with hypertriglyceridemia has not been determined.Guidelines for the management of very high triglyceride levels (500 mg/dL) suggest that reducing triglyceride levels is the primary treatment goal inthese patients to reduce the risk of acute pancreatitis. Treating LDL-C remains an important secondary goal. Other important parameters to consider inpatients with very high triglycerides include levels of apolipoprotein B (apo B), non-HDL-C, and very low density lipoprotein cholesterol (VLDL-C). Theeffect of Vascepa on the risk for pancreatitis in patients with hypertriglyceridemia has not been determined.It is estimated that over 40 million adults in the United States have elevated triglyceride levels 200 mg/dL and approximately 3 to 4 million peoplein the United States have very high triglyceride levels (500 mg/dL). Since 1976, mean triglyceride levels have increased, in concert with the growingepidemic of obesity, insulin resistance, and type 2 diabetes mellitus. In contrast, mean LDL-C levels have decreased.Mixed dyslipidemia refers to a condition in which patients have a combination of two or more lipid abnormalities including elevated triglycerides, lowHDL-C, and/or elevated LDL-C. Both hypertriglyceridemia and mixed dyslipidemia are components of a range of lipid disorders collectively referred to asdyslipidemia. Dyslipidemia has been linked to atherosclerosis, commonly referred to as hardening of the arteries.Limitations of Current TherapiesIt is estimated that approximately 4% or less of U.S. adults with triglyceride levels 200 mg/dL are currently receiving prescription medication forlowering triglycerides. Many of these patients are taking statin therapy directed primarily at lowering their LDL-C levels.The leading prescription treatments to lower triglyceride levels are fibrates (fenofibrate and gemfibrozil), statins and generic forms of an omega-3 fattyacid mixture known as Lovaza in the United States and as Omacor in Europe. The use of fenofibrates can lead to abnormal liver function tests (an increasein ALT (alanine transaminase) or AST (aspartate transaminase), which are liver enzymes, and are commonly measured clinically as a part of a diagnostic liverfunction test to determine liver health), especially when used with statins. 9®®Table of ContentsThe use of gemfibrozil can lead to rhabdomyolysis (severe breakdown of muscles), especially when used with a statin. Lovaza is comprised of omega-3 ethylesters, which the FDA has described as a complex mixture of eicosapentaenoic acid, or EPA, docosahexaenoic acid, or DHA, and other fatty acids. We believethat DHA may increase LDL-C levels and thereby partially offset one of the typically desired benefits of lipid-lowering therapies, which is lowering LDL-C.Also, in 2012, the FDA required an update to Lovaza product labeling to reflect the risk that Lovaza may increase the frequency of a heart rhythm problemknown as atrial fibrillation, or heart flutter. Also, in 2015, the FDA updated the Trilipix (a fenofibrate) product labeling and removed combination use withstatin therapy in mixed dyslipidemia patients as an indication due to a failed outcomes trial.Potential Benefits and Market Opportunity for VascepaVascepa is comprised of not less than 96% pure icosapent ethyl, or ethyl-EPA, and contains no DHA. We believe that the removal of DHA mitigatesagainst the LDL-C raising effect observed in omega-3 compositions that include DHA. Based on the results of the MARINE trial, Vascepa was the firstomega-3 based product to demonstrate statistically significant triglyceride reduction without a statistically significant increase in LDL-C in this very hightriglyceride population.We believe that the results of the MARINE trial and Vascepa’s EPA only/DHA-free composition suggest that Vascepa has the potential to become a“best-in-class” triglyceride-lowering agent in the United States and the European Union. If the REDUCE-IT cardiovascular outcomes study is successful,Vascepa could be the first omega-3 based therapy approved for lowering high triglycerides in patients with mixed dyslipidemia and for prevention ofcardiovascular events as an add-on to statin therapy in this population.We believe the potential market for Vascepa is large and growing. We estimate that drug treatment for hypercholesterolemia patients exceeds$67 billion per year in the United States, with sales dominated by statin therapies. U.S. sales of fibrates as a class of products were approximately $2.9 billionin 2016 with generic fenofibrate and gemfibrozil leading the class. U.S. gross sales of prescription omega-3 therapies in 2016 were over $1.2 billion withgeneric Lovaza leading the class.Clinical TrialsThe MARINE Trial (basis for currently FDA-approved label for Vascepa)The MARINE trial, the largest study ever conducted with the omega-3 fatty acid ethyl EPA in treating patients with very high triglycerides (500mg/dL), was a Phase 3, multi-center, placebo-controlled, randomized, double-blind, 12-week study. Patients were randomized into three treatment arms fortreatment with Vascepa 4 gram/day, 2 gram/day or placebo. Patient enrollment in this trial began in December 2009, and enrollment and randomization wascompleted in August 2010 at 229 patients. The primary endpoint in the trial was the percentage change in triglyceride level from baseline compared toplacebo after 12 weeks of treatment. The MARINE study primary endpoint was required to meet a stringent level of statistical significance of 1% (p < 0.01) inour special protocol assessment, or SPA, agreement with the FDA.In November 2010, we reported top-line data for the MARINE trial. In the trial, Vascepa met its primary endpoint at doses of 4 grams and 2 grams perday with median placebo-adjusted reductions in triglyceride levels of 33% (p < 0.0001) compared to placebo for 4 grams and 20% (p = 0.0051) compared toplacebo for 2 grams. The median baseline triglyceride levels were 703 mg/dL, 680 mg/dL and 657 mg/dL for the patient groups treated with placebo, 4 gramsof Vascepa and 2 grams of Vascepa, respectively.In a pre-specified secondary analysis in the subgroup of patients with baseline triglyceride > 750 mg/dL, representing 39% of all patients, the effect ofVascepa in reducing triglyceride levels compared to placebo was 45% for 4 grams and 33% for 2 grams, both statistically significant (p = 0.0001 for 4 gramsand p= 0.0016 for 2 grams, respectively). The median baseline triglyceride levels in this subgroup were 1052 mg/dL, 902 mg/dL and 10®Table of Contents948 mg/dL for placebo, 4-gram and 2-gram groups, respectively. Twenty-five percent of patients in this trial were also on background statin therapy. Thesepatients had greater median reduction in triglyceride levels, which was also statistically significant.Importantly, the significant reduction in triglycerides was not associated with a statistically significant increase in median LDL-C compared to placeboat either dose (-2.3% for the 4-gram group and +5.2% for the 2-gram group [both p=NS]). In addition, there was a statistically significant decrease in mediannon-HDL-C (total cholesterol less so-called “good cholesterol”) compared to placebo with both of the Vascepa treated groups (-18% for the 4-gram group [p< 0.001] and -8% for the 2-gram group [p < 0.05]).The MARINE trial results also included statistically significant reductions compared to placebo in several important lipid and inflammatorybiomarkers, including apo B (apolipoprotein B) (8.5%), Lp-PLA2 (lipoprotein-phospholipase A2) (13.6%), VLDL-C (very low-density lipoproteincholesterol) (28.6%), Total Cholesterol (16.3%), and hsCRP (high-sensitivity C-reactive protein) (36.0%) at the 4-gram dose. For these achieved endpoints,p-values were <0.01 for most and <0.05 for all. Apo B (apolipoprotein B) is believed to be a sensitive biomarker of cardiovascular risk and may be a betterpredictor of cardiovascular risk than LDL-C. Lp-PLA2 is an enzyme found in blood and atherosclerotic plaque; high levels have been implicated in thedevelopment and progression of atherosclerosis. In a post-hoc analysis of MARINE study data, Vascepa 4 g/day and 2 g/day statistically significantlyreduced ApoC-III levels by 25.1% (p < 0.0001) and 14.3% (p=0.0154) versus placebo, respectively. In the MARINE trial, patients treated with 4 grams perday of Vascepa experienced a significant reduction in median placebo-adjusted lipoprotein particle concentrations of total LDL and small LDL. Whenlooking at lipoprotein particle concentrations and sizes as measured with nuclear magnetic resonance spectroscopy, Vascepa 4 grams per day, compared withplacebo, significantly reduced median total LDL particle count by 16.3% (p=0.0006), which is an important factor in atherogenesis. LDL particle count andapo B are important risk markers for the prediction of cardiovascular events. Small LDL particle count, which is a common risk factor for cardiovascularevents in patients with diabetes, was reduced by 25.6% (p<0.0001) compared with placebo. Vascepa 2 grams per day, compared with placebo, significantlyreduced median small LDL particle count by 12.8% (p <0.05) and reduced median total LDL particle count by 1.1% (NS). LDL particle size did not changesignificantly for the 2 or 4 gram per day doses.Vascepa was well tolerated in the MARINE trial, with a safety profile comparable to placebo and there were no treatment-related serious adverse eventsobserved. No patient discontinued treatment of Vascepa during this study due to Vascepa-related adverse events. No significant changes in fasting bloodglucose, hemoglobin A1C, vital signs, electrocardiograms, or liver or kidney function were observed with either Vascepa dose.Patients enrolled in the MARINE trial were given the option to be treated with Vascepa for a period of up to 40 weeks after their last dose in thedouble-blind portion of the trial. Once participants completed the randomized, double blind, placebo-controlled 12-week MARINE registration trial, patientsin all three randomized groups (4 grams, 2 grams and placebo) were offered the opportunity to participate in the open label extension, or OLE, phase. Patientsin the OLE phase received 4 grams per day of Vascepa for a period of up to an additional 40 weeks. As is typical of such extension phases, the OLE phase wasnot a controlled trial, as differentiated from the randomized, double blind, placebo-controlled 12-week MARINE registration trial. In the OLE phase,participants were not randomized at entry, Vascepa administration was open-label (and thus not blinded), and no placebo group was maintained. Also, oncepatients entered in the OLE phase, investigators were free to add or modify other lipid-altering nutritional, lifestyle and drug treatment regimens. Given thelack of randomization, the open-label design, the addition of various other lipid-altering drugs and changes to doses of existing lipid-altering drugs, as wellas the lack of placebo control, neither we nor our independent advisors were able to draw efficacy conclusions from the data. However, we have concludedthat the MARINE OLE phase revealed no new safety signals after an additional 40 weeks of exposure to Vascepa, whether used alone or in combination withother lipid-altering regimens. 11Table of ContentsThe ANCHOR Trial (promoted in the United States under court declaration)The ANCHOR trial was a multi-center, placebo-controlled, randomized, double-blind, 12-week pivotal study in patients with high triglycerides (200and <500 mg/dL) who were also receiving optimized statin therapy. Patients were randomized into three arms for treatment with Vascepa 4 gram/day, 2gram/day or placebo. Patient enrollment in this trial began in January 2010, and enrollment and randomization was completed in February 2011 at 702patients. The primary endpoint in the trial was the percentage change in triglyceride level from baseline compared to placebo after 12 weeks of treatment.In April 2011, we reported top-line results from the ANCHOR trial. The ANCHOR trial met its primary endpoint at doses of 4 grams and 2 grams perday with median placebo-adjusted reductions in triglyceride levels of 21.5% (p<0.0001 value) for 4 grams and 10.1% (p=0.0005) for 2 grams. The medianbaseline triglyceride levels were 259 mg/dL, 265 mg/dL and 254 mg/dL for the patient groups treated with placebo, 4 grams and 2 grams of Vascepa per day,respectively. The analysis of subgroups by baseline triglyceride tertiles showed that higher baseline triglycerides resulted in greater triglyceride reductions.One of the trial’s secondary endpoints was to demonstrate a lack of elevation in LDL-C, the primary target of cholesterol lowering therapy. The trial’snon-inferiority criterion for LDL-C was met at both Vascepa doses. The upper confidence boundaries for both doses were below the pre-specified +6% LDL-Cthreshold limit. At the 4-gram dose the upper confidence boundary was below zero (-1.7%) and at the 2-gram dose the upper confidence boundary was closeto zero (0.5%). For the 4 grams per day group, LDL-C decreased significantly by 6.2% from baseline versus placebo, demonstrating superiority over placebo(p=0.0067). For the 2-gram group, LDL-C decreased by 3.6% from baseline versus placebo (p=0.0867), which is not a statistically significant decrease.Other secondary efficacy endpoints included the median placebo-adjusted percent change in non-high-density lipoprotein cholesterol (non-HDL-C),apolipoprotein B (apo B), and lipoprotein-associated phospholipase A2 (Lp-PLA2). The 4-gram dose was associated with statistically significant reductionsin non-HDL-C (13.6%, p<0.0001), apo B (9.3%, p<0.0001), Lp-PLA2 (19%, p<0.0001) and high-sensitivity C-reactive protein (hsCRP) (22%, p<0.001), atweek 12 compared to placebo. A recently published analysis showed that the Vascepa 4-gram daily dose in the ANCHOR study also significantly decreasedlevels of the inflammatory marker oxidized low-density lipoprotein relative to placebo by 13% (p < 0.0001). In a separate, post-hoc analysis of study data,Vascepa 4 g/day statistically significantly reduced ApoC-III levels by 25.1% in MARINE (p < 0.0001) and by 19.2% in ANCHOR (p < 0.0001) versusplacebo.Vascepa was well tolerated in the ANCHOR trial with a safety profile comparable to placebo and there were no treatment-related serious adverse eventsobserved. No significant changes in fasting blood glucose, hemoglobin A1C, vital signs, electrocardiograms, or liver or kidney function were observed witheither Vascepa dose. The safety results from the ANCHOR trial are included in the current FDA-approved label for Vascepa.In April 2015, we received a Complete Response Letter, or CRL, from the FDA in response to our supplemental new drug application, or sNDA, thatsought approval of Vascepa for use in patients with mixed dyslipidemia, based on the successful ANCHOR study. The CRL followed an October 2013rescission by the FDA of a special protocol assessment, or SPA, agreement and three failed attempts by us to appeal that rescission at FDA. The FDA hasacknowledged the success of the ANCHOR study, which met all primary and secondary endpoints. However, FDA determined that there were insufficient datato conclude that drug-induced changes in serum triglycerides could be recognized by the FDA as a valid surrogate for reducing cardiovascular risk in theANCHOR population for the purpose of regulatory approval of a drug targeted at a triglyceride-lowering indication in this population. The FDA hasacknowledged that the standard of proof required by the FDA for approval of a new drug indication is higher than that generally used to inform patienttreatment guidelines and that used by physicians in clinical practice. The FDA did not determine that the drug-induced effects of Vascepa, which go beyondtriglyceride-lowering, would not actually reduce cardiovascular risk in this population and the FDA has encouraged us to complete the REDUCE-IToutcomes study. Based on our communications with the 12Table of ContentsFDA, we expect that final positive results from the REDUCE-IT outcomes study will be required for label expansion for Vascepa.In May 2015, we and a group of independent physicians filed a lawsuit in federal court to permit us to promote to healthcare professionals the use ofVascepa in patients with mixed dyslipidemia so long as the promotion is truthful and non-misleading. This use reflects recognized medical practice but is notcovered by current FDA-approved labeling for the drug. Historically, FDA has considered promotion of drug uses not covered by FDA-approved labelling tobe illegal off-label promotion, even if such promotion is truthful and non-misleading. In August 2015, we were granted preliminary relief in the form of adeclaratory judgment in this lawsuit. The court declaration permits us to promote to healthcare professionals the FDA-reviewed and agreed effects of Vascepademonstrated in the ANCHOR clinical trial and presentation of the current state of scientific research related to the potential of Vascepa to reduce the risk ofcardiovascular disease including through use of peer-reviewed scientific publications of available data. In August 2015, we began to communicatepromotional information beyond the MARINE indication to healthcare professionals in the United States as permitted by this court declaration and in March2016, the parties obtained court approval of negotiated settlement terms under which the FDA and the U.S. government agreed to be bound by the court’sconclusions from the August 2015 declaration that we may engage in truthful and non-misleading speech promoting the off-label use of Vascepa and thatcertain statements and disclosures that we proposed to make to healthcare professionals were truthful and non-misleading. While we believe we are nowpermitted under applicable law to more broadly promote Vascepa, the FDA-approved labeling for Vascepa did not change as a result of this litigation andsettlement, and neither government nor other third-party coverage or reimbursement to pay for the off-label use of Vascepa promoted under the courtdeclaration was required.Observed Efficacy of Ethyl-EPAIn Japan, ethyl-EPA is marketed under the product name of Epadel by Mochida Pharmaceutical Co. and is indicated for hyperlipidemia and peripheralvascular disease. In an outcomes study called the Japan EPA Lipid Intervention Study, or JELIS study, which consisted of more than 18,000 patients followedover multiple years, Epadel, when used in conjunction with statins, was shown to reduce cardiovascular events by 19% compared to the use of statins alone.In this study, cardiovascular events decreased by approximately 53% compared to statins alone in the subset of primary prevention patients with triglyceridelevels of 150 mg/dL (median of 272 mg/dL at entry) and HDL-C <40 mg/dL. Epadel has been approved and available by prescription in Japan for over adecade. In 2013, the Japan Ministry of Health approved Epadel for over-the-counter sales. JELIS provides supportive but not conclusive data that EPA drugtherapy may reduce major coronary events. JELIS results cannot be generalized to populations outside of Japan due to limitations in the study’s design.Further study is needed, such as the REDUCE-IT study, to determine the clinical benefit, if any, of EPA therapy in statin-treated patients with elevatedtriglyceride levels.Observed Clinical Safety of VascepaPrior to commencing the MARINE and ANCHOR trials, we conducted a pre-clinical program for Vascepa, including toxicology and pharmacologystudies. In addition, we previously investigated Vascepa in central nervous system disorders in several double-blind, placebo-controlled studies, includingPhase 3 trials in Huntington’s disease. Over 1,000 patients have been dosed with Vascepa in these studies, with over 100 receiving continuous treatment for ayear or more. In all studies performed to date, Vascepa has shown a favorable safety and tolerability profile. In both the MARINE and ANCHOR trials,patients dosed with Vascepa demonstrated a safety profile similar to placebo. There were no treatment-related serious adverse events in the MARINE study orin the ANCHOR study. In the MARINE and ANCHOR trials, the most commonly reported adverse reaction (incidence >2% and greater than placebo) inVascepa treated patients was arthralgia (joint pain) (2.3% for Vascepa vs. 1.0% for placebo). There was no reported adverse reaction > 3% and greater thanplacebo.In addition to the MARINE and ANCHOR trials, we completed a 28-day pharmacokinetic study in healthy volunteers, a 26-week study to evaluate thetoxicity of Vascepa in transgenic mice and multiple pharmacokinetic 13Table of Contentsdrug-drug interaction studies in healthy subjects in which we evaluated the effect of Vascepa on certain common prescription drugs. All findings from thesestudies were consistent with our expectations and confirmed the overall safety profile of Vascepa.The REDUCE-IT Study (currently ongoing cardiovascular outcomes study)In August 2011, we reached agreement with the FDA on a SPA for the design of the REDUCE-IT (Reduction of Cardiovascular Events with EPA—Intervention Trial) cardiovascular outcomes study. A SPA is an evaluation by the FDA of a protocol with the goal of reaching an agreement that the Phase 3trial protocol design, clinical endpoints, and statistical analyses are acceptable to support regulatory approval. The FDA agreed that, based on theinformation we submitted to the agency, the design and planned analysis of the REDUCE-IT study adequately addressed the objectives necessary to supporta regulatory submission. A SPA is generally binding upon the FDA unless a substantial scientific issue essential to determining safety or efficacy of the drugis identified after the testing begins. Moreover, any change to a study protocol can invalidate a SPA.In September 2011, we engaged a clinical research organization, or CRO, and began initial trial and clinical site preparation for REDUCE-IT. InDecember 2011, we announced that the first patient was dosed in the study. The study duration is dependent on the rate of clinical events in the study whichrate may be affected by the number of patients enrolled in the study, the epidemiology of the patients enrolled in the study, and the length of time that theenrolled patients are followed.The REDUCE-IT study is designed to evaluate the efficacy of Vascepa in reducing major cardiovascular events in an at-risk patient population alsoreceiving statin therapy. REDUCE-IT is a multinational, prospective, randomized, double-blind, placebo-controlled, parallel-group study to evaluate theeffectiveness of Vascepa, as an add-on to statin therapy, in reducing first major cardiovascular events in an at-risk patient population compared to statintherapy alone. The control arm of the study is comprised of patients on optimized statin therapy plus placebo. The active arm of the study is comprised ofpatients on optimized statin therapy plus Vascepa. All subjects enrolled in the study will have elevated triglyceride levels and either coronary heart diseaseor risk factors for coronary heart disease. This study is being conducted internationally.In 2016, we completed patient enrollment and randomization of 8,175 individual patients into the REDUCE-IT study, exceeding the 8,000 patientstargeted for the trial.Completion of the REDUCE-IT study is designed to occur after reaching 1,612 aggregate primary cardiovascular events. Based on projected eventrates, we estimate the onset of the target aggregate number of cardiovascular events to be reached near the end of 2017 with study results then expected to beavailable in 2018. In addition, since its inception in 2011, our REDUCE-IT SPA agreement with the FDA has provided for periodic safety reviews and aninterim efficacy and safety analysis by the independent DMC at approximately 60% of the target aggregate number of primary cardiovascular events. InAugust 2016, we announced an amendment to our REDUCE-IT SPA agreement with FDA that reaffirmed FDA concurrence on key elements of the study,defined details of the statistical analysis plan for the study, expanded to greater than 30 the pre-specified secondary and tertiary endpoints in the study, andadded a second interim efficacy and safety analysis by the DMC at approximately 80% of the target aggregate number of primary cardiovascular events. Theperiodic safety reviews and interim efficacy and safety analyses are conducted confidentially by the study’s DMC.In March 2016, we announced that the onset of approximately 60% of the target aggregate number of primary cardiovascular events had triggeredpreparation for the first pre-specified interim analysis of efficacy and safety results. Such analysis included the first review of unblinded efficacy data by theindependent DMC. The DMC completed its review of the interim analysis in September 2016 and, consistent with previously stated expectations,recommended that the trial continue as planned without modification. The second planned interim analysis of efficacy results will be triggered by the onsetof approximately 80% of the target aggregate number of primary cardiovascular events in the study. Based on historical event rates, we anticipate that theonset of 14Table of Contentsapproximately 80% of events will occur in the first half of 2017, with the second pre-specified interim efficacy analysis by the DMC expected in or about thethird quarter of 2017. The interim efficacy analysis will be accompanied by an interim safety analysis by the DMC. As is typical, the statistical threshold fordefining overwhelming efficacy on the primary endpoint at interim analyses is considerably higher than the threshold for defining statistical significance atthe end of the study. In addition, we have requested the DMC to not recommend stopping the study early based only upon the achievement of statisticalsignificance for the primary endpoint, but to ensure that supportive trends of benefit are also consistently observed in certain secondary endpoints andsubpopulations before recommending that the study be stopped early for overwhelming efficacy. This is the same approach we asked the DMC to employ inconnection with the REDUCE-IT study 60% interim analysis. It is our expectation that the 80% interim analysis will also result in a recommendation by theDMC to continue the trial. By design, it is most common for cardiovascular outcomes studies not to be stopped upon an interim look. We remain blinded toall data from the study. Unless overwhelming efficacy and safety is declared by the DMC at an interim look or the study is halted due to a patient safetyconcern, Amarin personnel will remain blinded to the efficacy and safety data from the REDUCE-IT study until the study is complete.Since patient enrollment commenced in 2011, more than 26,000 patient years of study experience have been accumulated in REDUCE-IT. The DMChas reviewed unblinded safety data on a quarterly basis since 2013 and, after each such review of unblinded safety data to date, the DMC has recommendedto us that the study be continued as planned.Our scientific rationale for the REDUCE-IT study is supported by (i) epidemiological data that suggests elevated triglyceride levels correlate withincreased cardiovascular disease risk, (ii) genetic data that suggests triglyceride and/or triglyceride-rich lipoproteins (as well as low-density lipoproteincholesterol (LDL cholesterol), known as bad cholesterol) are independently in the causal pathway for cardiovascular disease and (iii) clinical data thatsuggest substantial triglyceride reduction in patients with elevated baseline triglyceride levels correlates with reduced cardiovascular risk. Our scientificrationale for the REDUCE-IT study is also supported by research on the putative cardioprotective effects of EPA as presented in scientific literature. It ispossible that the effects of EPA may be due not to a single mode of action, such as triglyceride lowering, but rather to multiple mechanisms working together.Studies in the scientific literature explore potentially beneficial effects of EPA on multiple atherosclerosis processes, including endothelial function,oxidative stress, foam cell formation, inflammation/cytokines, plaque formation/progression, platelet aggregation, thrombus formation, and plaque rupture.The REDUCE-IT study is needed to determine the clinical benefit, if any, of EPA therapy in statin-treated patients with elevated triglyceride levels.We currently expect that final positive results of the REDUCE-IT study will be required for FDA label expansion of Vascepa. Based on the results ofREDUCE-IT, we may seek additional indications for Vascepa beyond the indications studied in the ANCHOR and MARINE trials such as potential indicateduses for prevention of cardiovascular events, although there can be no assurance as to whether the results of the study will support any such indication.New Lipid Compounds and other Preclinical ProgramsWe are also considering development of other next generation compounds based on our internal lipid science expertise, including potentialcombination and derivative therapies.In August 2013, we completed dosing of AMR102, a fixed dose combination of Vascepa and a leading statin product. The study is a randomized,open-label, single-dose, 4-way cross-over study to continue testing of the relative bioavailability of AMR102 capsules, Vascepa capsules with the selectedstatin taken concomitantly, Vascepa taken alone and the selected statin taken alone. The results of this study support the feasibility of AMR102. We havesuspended additional development of AMR102 pending FDA approval of label expansion of Vascepa, anticipated to occur no sooner than after FDA reviewof the results from the REDUCE-IT study. 15Table of ContentsWe believe that Vascepa and other lipid-based compositions may have an impact on a number of biological factors in the body such as anti-inflammatory mechanisms, cell membrane composition and plasticity, triglyceride levels and regulation of glucose metabolism. Currently all otherdevelopment activities are at formulation or pre-clinical stages.Manufacturing and Supply for VascepaWe currently use third-party manufacturers and suppliers to manufacture the clinical and commercial active pharmaceutical ingredient, or API, withinVascepa, and to encapsulate and package Vascepa. The FDA approval of Vascepa in July 2012 included the approval of one API manufacturer, NisshinPharma, Inc., or Nisshin, and one API encapsulator, Patheon, Inc., or Patheon (formerly Banner Pharmacaps). Nisshin and Patheon are the API manufacturerand API encapsulator, respectively, with which we have had the longest working relationships. Their facilities were approved by the FDA followingsuccessful preapproval inspections and they remain active producers of Vascepa.We currently rely on Patheon and Capsugel Plöermel SAS for the encapsulation of Vascepa and we have an encapsulation agreement with one otherqualified commercial API encapsulator, Catalent Pharma Solutions.In addition to purchasing API from Nisshin, we have also purchased API from Chemport, Inc., or Chemport. In December 2012, we announced oursubmissions of two sNDAs to the FDA seeking approval for Chemport and BASF (formerly Equateq Limited) as additional Vascepa API suppliers. In April2013, the FDA approved our sNDAs covering Chemport and BASF as additional Vascepa API suppliers. On December 30, 2013, we issued a notice oftermination of our API agreement to BASF as a result of BASF’s non-compliance with the terms of such agreement period and the agreement subsequentlyterminated in the first quarter of 2014. BASF remains an approved API supplier. In December 2012, we announced an agreement with an exclusiveconsortium of companies led by Slanmhor Pharmaceutical, Inc., or Slanmhor. We submitted a sNDA in August 2013 seeking FDA approval for this supplier tomanufacture Vascepa API and in July 2014 the FDA approved our sNDA for Slanmhor as an API supplier. In July 2014, we terminated the supply agreementwith Slanmhor and subsequently, in June 2015, entered into a new supply agreement with Finorga SAS, or Novasep. API manufactured by Novasep waspreviously approved by the FDA in July 2014.The API material that constitutes ethyl-EPA is a modified, naturally occurring substance which is sourced from qualified producers of specific fish oils.A limited number of other manufacturers have the ability, scale, know-how and suitable facilities to produce ethyl-EPA to the required level of purity. Amongthe conditions for FDA approval of a pharmaceutical product is the requirement that the manufacturer’s quality control and manufacturing proceduresconform to pharmaceutical current Good Manufacturing Practice, or cGMP, which must be followed at all times. The FDA typically inspects manufacturingfacilities before regulatory approval of a product candidate, such as Vascepa, and on a periodic basis after the initial approval. Consistent with cGMPregulations, pharmaceutical manufacturers must expend resources and time to ensure compliance with product specifications as well as production, recordkeeping, quality control, reporting, and other regulatory requirements.Some of our agreements with our API suppliers are exclusive and may include minimum purchase commitments. During 2015 and 2016, we fully metthe aggregate minimum purchase requirements for metric tons of API contained in our supply agreements. Under the supply agreements, we can purchasemore than the minimum requirements. Certain of these agreements contemplate phased capacity expansion aimed at creating sufficient volumes to meetanticipated demand for Vascepa. Certain of these agreements contain provisions for reduced payments for unmet annual volume requirements.Our Commercialization PlansWe currently market Vascepa in the United States through our direct sales force of approximately 150 sales professionals, including salesrepresentatives and their managers. We also employ various marketing and medical 16Table of Contentsaffairs personnel to support our commercialization of Vascepa. We currently target clinicians who are top prescribers of lipid regulating therapies. During theperiod from January 2013, when Vascepa was commercially launched in the United States, until October 2013, when the FDA notified us that it rescinded theANCHOR study SPA agreement, our direct sales force was larger, consisting of approximately 275 sales representatives. Since October 2013, the size of ourdirect sales force has included approximately 125 to 140 sales representatives with focus on select sales territories that we believe have demonstrated thegreatest potential for Vascepa sales growth. Commencing in May 2014, in addition to Vascepa promotion by our sales representatives, no less than 250 KowaPharmaceuticals America, Inc. sales representatives began devoting a substantial portion of their time to promoting Vascepa in the United States. We alsoemploy various marketing personnel to support our commercialization of Vascepa.Since commercial launch of Vascepa in January 2013, we have promoted Vascepa based on the MARINE clinical trial data as reflected in theFDA-approved label for Vascepa. In August 2015, we and our co-promotion partner began communicating promotional information beyond MARINEclinical trial data to targeted healthcare professionals. Such qualified communications are being made pursuant to the August 7, 2015 federal district courtdeclaration and related March 2016 settlement allowing truthful and non-misleading promotion of the FDA-reviewed and agreed effects of Vascepademonstrated in the ANCHOR clinical trial and presentation of the current state of scientific research related to the potential of Vascepa to reduce the risk ofcardiovascular disease including through use of peer-reviewed scientific publications of available data.Until results of our cardiovascular outcomes trial, REDUCE-IT, show otherwise, we plan to continue to promote Vascepa based on the effects ofVascepa on surrogate biomarkers as studied in MARINE and ANCHOR. After results of REDUCE-IT are available, on the assumption that the studydemonstrates that Vascepa is effective in lowering the rate of major adverse cardiovascular events in patients with risk factors similar to those studied inREDUCE-IT, we intend to expand the size of our U.S. direct sales force and seek to expand promotion of Vascepa based on the results of the REDUCE-ITtrial.Outside of the United States, we have expanded our commercialization activities through partnering arrangements in certain territories. In February2015, we entered into a Development, Commercialization and Supply Agreement, or the DCS Agreement, with Eddingpharm (Asia) Macao CommercialOffshore Limited, or Eddingpharm, related to the development and commercialization of Vascepa in Mainland China, Hong Kong, Macau and Taiwan, or theChina Territory. Under the DCS Agreement, Eddingpharm will be solely responsible for development and commercialization activities in the China Territoryand associated expenses. Additionally, Eddingpharm may be required to conduct clinical trials in the China Territory to secure regulatory approval.Significant commercialization of Vascepa in the China Territory is several years away, if at all. If Eddingpharm is not able to effectively develop andcommercialize Vascepa in the China Territory, we may not be able to generate revenue from the DCS Agreement resulting from the sale of Vascepa in theChina Territory.In March 2016, we entered into an agreement with Biologix FZCo, or Biologix, to register and commercialize Vascepa in several Middle Eastern andNorth African countries. Under the terms of the distribution agreement, we granted to Biologix a non-exclusive license to use our trademarks in connectionwith the importation, distribution, promotion, marketing and sale of Vascepa in the Middle East and North Africa territory. Commercialization across theregion, as in China, is several years away in most jurisdictions and subject to similar risks.We continue to assess other partnership opportunities for licensing Vascepa to partners outside of the United States.CompetitionThe biotechnology and pharmaceutical industries are highly competitive. There are many pharmaceutical companies, biotechnology companies,public and private universities and research organizations actively 17Table of Contentsengaged in the research and development of products that may be similar to our products. It is probable that the number of companies seeking to developproducts and therapies similar to our products will increase. Many of these and other existing or potential competitors have substantially greater financial,technical and human resources than we do and may be better equipped to develop, manufacture and market products. These companies may develop andintroduce products and processes competitive with or superior to ours. In addition, other technologies or products may be developed that have an entirelydifferent approach or means of accomplishing the intended purposes of our products, which might render our technology and products noncompetitive orobsolete.Our competitors both in the United States and Europe include large, well-established pharmaceutical companies, specialty pharmaceutical sales andmarketing companies, and specialized cardiovascular treatment companies. GlaxoSmithKline plc, which currently sells Lovaza, a prescription-only omega-3fatty acid indicated for patients with severe hypertriglyceridemia was approved by FDA in 2004 and has been on the market in the United States since 2005.As described below, multiple generic versions of Lovaza are now available in the United States. Other large companies with competitive products includeAbbVie, Inc., which currently sells Tricor and Trilipix for the treatment of severe hypertriglyceridemia and Niaspan, which is primarily used to raiseHDL-C but is also used to lower triglycerides. Generic versions of Tricor, Trilipix, and Niaspan are also now available in the United States. In addition, inMay 2014, Epanova (omega-3-carboxylic acids) capsules, a free fatty acid form of omega-3 (comprised of 55% EPA and 20% DHA), was approved by theFDA for patients with severe hypertriglyceridemia. Epanova was developed by Omthera Pharmaceuticals, Inc., and is now owned by AstraZenecaPharmaceuticals LP (AstraZeneca). Also, in April 2014, Omtryg, another omega-3-acid fatty acid composition developed by Trygg Pharma AS, received FDAapproval for severe hypertriglyceridemia. Neither Epanova nor Omtryg have been commercially launched, but could launch at any time. Each of thesecompetitors, other than potentially Trygg, has greater resources than we do, including financial, product development, marketing, personnel and otherresources.Currently, six manufacturers have launched generic versions of Lovaza. In April 2014, Teva Pharmaceuticals USA Inc., or Teva, launched a genericversion of Lovaza after winning its patent litigation against Pronova BioPharma Norge AS, now owned by BASF, which owns such patent rights. In June2014 and September 2014, Par Pharmaceutical Inc., or Par, and Apotex Inc., or Apotex, respectively, received FDA approval of their respective versions ofgeneric Lovaza. Par launched a generic version of Lovaza in July 2014. In March 2011, Pronova/BASF entered into an agreement with Apotex to settle itspatent litigation in the United States related to Lovaza. Pursuant to the terms of the settlement agreement, Apotex launched a generic version of Lovaza inJanuary 2015. Prasco Labs launched a generic version of Lovaza in March 2015 and AvKARE Inc., or AvKARE, launched its version in May 2015. AvKAREsupplies government agencies and does not participate in the commercial marketplace. Amneal Pharmaceuticals launched a generic version of Lovaza inJanuary 2016. In December 2016, Golden State Medical Supply launched a generic version of Lovaza. Like AvKARE, Golden State Medical Supply onlysupplies products to government agencies and does not participate in the commercial marketplace.In addition, we are aware of other pharmaceutical companies that are developing products that, if approved and marketed, would compete withVascepa. We understand that Acasti Pharma, or Acasti, a subsidiary of Neptune Technologies & Bioresources Inc., announced in December 2015 that itintends to pursue a regulatory pathway under section 505(b)(2) of the Federal Food, Drug, and Cosmetic Act, or FDCA, for its omega-3 prescription drugcandidate, CaPre, derived from krill oil for the treatment of hypertriglyceridemia. In September 2016, Acasti announced positive results from its pivotalbioavailability bridging study comparing CaPre to Lovaza, establishing a scientific bridge between the two that is expected to support the feasibility of a505(b)(2) regulatory pathway. Acasti intends to complete long-term toxicity studies in the next 6-9 months and follow these with a Phase 3 clinical programto assess the safety and efficacy of CaPre in patients with very high (500 mg/dL) triglycerides. We believe Sancilio & Company, or Sancilio, is alsodeveloping potential treatments for hypertriglyceridemia based on omega-3 fatty acids. To our knowledge, Sancilio is pursuing a regulatory pathway undersection 505(b)(2) of the FDCA for its product and submitted an Investigational New Drug 18®®®®®®Table of ContentsApplication, or IND, in July 2015. Sancilio completed two pharmacokinetic studies and Phase 2 bioavailability studies (FASTR I&II), with one comparingSC401 to Lovaza. We expect the company to initiate a pivotal clinical Phase 3 study as the next step in development.In addition, we are aware that Matinas BioPharma, Inc. is developing an omega-3-based therapeutic for the treatment of severe hypertriglyceridemiaand mixed dyslipidemia. Matinas BioPharma, Inc. has filed an IND with the FDA to conduct a human study in the treatment of severe hypertriglyceridemia.Akcea Therapeutics/Ionis Pharmaceuticals (formerly Isis Pharmaceuticals), or Akcea/Ionis, announced favorable Phase 3 results of volanesorsen (formerlyISIS-APOCIII), a drug candidate administered through weekly subcutaneous injections, in patients with severe hypertriglyceridemia (COMPASS trial).Phase 2 trials are currently ongoing studying volanesorsen in patients with familial chylomicronemia syndrome (FCS) and familial partial lipodystrophy(FPL) with data expected in 2017 and 2019. In January 2017, Akcea/Ionis announced a strategic collaboration and option agreement with Novartis wherebyNovartis will help develop (including funding cardiovascular outcomes studies) and commercialize products emerging from this collaboration, includingvolanesorsen. Madrigal Pharmaceuticals has completed Phase 1 clinical testing of MGL-3196 for the treatment of high triglycerides and various lipidparameters in patients. Finally, Gemfire Therapeutics announced favorable results from a Phase 2 trial to evaluate the safety and efficacy of gemcabene, anoral, once-daily pill, in the treatment of patients with homozygous familial hypercholesterolemia (HoFH) on stable lipid-lowering therapy. The novelmechanism of action of gemcabene may support multiple indications including a potential severe triglyceride reduction. Three Phase 2b trials of gemcabeneare ongoing in patients with HoFH on stable lipid-lowering therapy, in patients with severe hypertriglyceridemia, and in patients with hypercholesterolemiaon a high-intensity stable statin therapy with or without ezetimibe.Vascepa also faces competition from dietary supplement companies marketing omega-3 products as nutritional supplements. We cannot be surephysicians and pharmacists will view the FDA-approved prescription-only status, EPA-only purity of Vascepa and stringent regulatory oversight assignificant advantages versus omega-3 dietary supplements.In addition, several generic drug companies have sought to challenge the validity and enforceability of our patents and have submitted to FDAapplications for approval of generic versions of Vascepa.Regulatory MattersGovernment Regulation and Regulatory MattersAny product development activities related to Vascepa or products that we may develop or acquire in the future will be subject to extensive regulationby various government authorities, including the FDA and comparable regulatory authorities in other countries, which regulate the design, research, clinicaland non-clinical development, testing, manufacturing, storage, distribution, import, export, labeling, advertising and marketing of pharmaceutical productsand devices. Generally, before a new drug can be sold, considerable data demonstrating its quality, safety and efficacy must be obtained, organized into aformat specific to each regulatory authority, submitted for review and approved by the regulatory authority. The data is generated in two distinctdevelopment stages: pre-clinical and clinical. Drugs must be approved by the FDA through the NDA process before they are first marketed in the UnitedStates. For new chemical entities, the pre-clinical development stage generally involves synthesizing the active component, developing the formulation,determining the manufacturing process and controls, as well as carrying out non-human toxicology, pharmacology and drug metabolism studies whichsupport subsequent clinical testing.The clinical stage of development can generally be divided into Phase 1, Phase 2 and Phase 3 clinical trials. In Phase 1, generally, a small number ofhealthy volunteers are initially exposed to a single dose and then multiple doses of the product candidate. The primary purpose of these studies is to assessthe metabolism, pharmacologic action, side effect tolerability and safety of the drug. Phase 2 trials typically involve studies in 19RxTable of Contentsdisease-affected patients to determine the dose required to produce the desired benefits. At the same time, safety and further pharmacokinetic andpharmacodynamic information is collected. Phase 3 trials generally involve large numbers of patients at multiple sites, in multiple countries and are designedto provide the pivotal data necessary to demonstrate the effectiveness of the product for its intended use, its safety in use, and may include comparisons withplacebo and/or other comparator treatments. The duration of treatment is often extended to mimic the actual use of a product during marketing.United States Drug DevelopmentIn the United States, the process of obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local, and foreignstatutes and regulations require the expenditure of substantial time and financial resources. Failure to comply with the applicable United States requirementsat any time during the product development process, approval process or after approval, may subject an applicant to administrative or judicial sanctions.These sanctions could include the FDA’s refusal to approve pending applications, withdrawal of an approval, a clinical hold, warning letters, product recalls,product seizures, total or partial suspension of production or distribution injunctions, fines, refusals of government contracts, restitution, disgorgement, orcivil or criminal penalties. Any agency or judicial enforcement action could have a material adverse effect on us.Prior to the start of human clinical studies for a new drug in the United States, preclinical laboratory and animal tests are often performed under theFDA’s Good Laboratory Practices regulations, or GLP, and an investigational new drug application, or IND, is filed with the FDA. Similar filings are requiredin other countries; however, data requirements and other information needed for a complete submission may differ in other countries. The amount of data thatmust be supplied in the IND depends on the phase of the study. Phase 1 studies typically require less data than larger Phase 3 studies. A clinical plan must besubmitted to the FDA prior to commencement of a clinical trial. If the FDA has concerns about the clinical plan or the safety of the proposed studies, it maysuspend or terminate the study at any time. Studies must be conducted in accordance with Good Clinical Practice, or GCP, and regular reporting of studyprogress and any adverse experiences is required. Studies are also subject to review by independent institutional review boards, or IRBs, responsible foroverseeing studies at particular sites and protecting human research study subjects. An independent IRB may also suspend or terminate a study onceinitiated.NDA and FDA Review ProcessFollowing trial completion, trial data is analyzed to determine safety and efficacy. Data is then filed with the FDA in an NDA along with proposedlabeling for the product and information about the manufacturing and testing processes and facilities that will be used to ensure product quality. The NDAmust contain proof of safety, purity, potency and efficacy, which entails extensive pre-clinical and clinical testing. FDA approval of an NDA must beobtained before first marketing of a drug in the United States.The FDA will likely re-analyze the clinical trial data, which could result in iterative discussions between the FDA and us during the review process.The review and evaluation of applications by the FDA is extensive and time consuming and may take longer than originally planned to complete. The FDAmay conduct a pre-approval inspection of the manufacturing facilities for the new product to determine whether they comply with current GoodManufacturing Practice, or cGMP, requirements and may also audit data from clinical and pre-clinical trials.There is no assurance that the FDA will ultimately approve a drug product for marketing in the United States. Even if future indications for Vascepa areapproved, the FDA’s review will be lengthy and we may encounter significant difficulties or costs during the review process. After approving any drugproduct, the FDA may require post-marketing testing and surveillance to monitor the effects of approved products or it may place conditions on approvalsincluding potential requirements or risk management plans that could restrict the commercial promotion, distribution, prescription or dispensing of products.Product approvals may be withdrawn for non-compliance with regulatory standards or if problems occur following initial marketing. 20Table of ContentsOff-label Promotion in the United StatesThe FDCA has been interpreted by the FDA to make it illegal for pharmaceutical companies to promote their FDA-approved products for uses that havenot been approved by the FDA. Companies that market drugs for off-label uses or indications have been subject to related costly litigation, criminal penaltiesand civil liability under the FDCA and the False Claims Act.In May 2015, we and a group of independent physicians filed a lawsuit against the FDA seeking a federal court declaration that would permit us andour agents to promote to healthcare professionals the use of Vascepa in patients with mixed dyslipidemia and promote on the potential of Vascepa to reducethe risk of cardiovascular disease so long as the promotion is truthful and non-misleading. This use of Vascepa at issue reflects recognized medical practicebut was not approved by the FDA and is thus not covered by current FDA-approved labeling for the drug. Promotion of an off-label use is considered by theFDA to be illegal under the FDCA. The lawsuit, captioned Amarin Pharma, Inc., et al. v. Food & Drug Administration, et al., 119 F. Supp. 3d 196 (S.D.N.Y.2015), was filed in the United States District Court for the Southern District of New York. In the lawsuit, we contended principally that FDA regulationslimiting off-label promotion of truthful and non-misleading information are unconstitutional under the freedom of speech clause of the First Amendment tothe U.S. Constitution as applied in the case of our proposed promotion of Vascepa. The physicians in the suit regularly treat patients at risk of cardiovasculardisease and, as the complaint contended, have First Amendment rights to receive truthful and non-misleading information from Amarin. The suit was basedon the principle that better informed physicians make better treatment decisions for their patients. The FDA opposed this lawsuit but did not dispute theveracity of the subject ANCHOR clinical trial data, the safety data from which is already in FDA-approved labeling of Vascepa, or the peer-reviewed researchrelated to Vascepa and the potential for cardiovascular risk reduction.In connection with this litigation, the FDA sent a detailed letter to us on June 5, 2015 that confirmed the validity of the ANCHOR trial results. Theletter also sought to clarify how, in the FDA’s view, applicable law and FDA policies apply to the communications proposed in our complaint. The FDAstated in this letter that it did not have concerns with much of the information we proposed to communicate and provided us with guidance on the FDA’sview of lawful, but limited paths for the dissemination and communication to healthcare professionals of the effects of Vascepa demonstrated in theANCHOR clinical trial and use of peer-reviewed scientific publications in the context of appropriate disclaimers.In August 2015, we were granted preliminary relief in this lawsuit through the court’s declaratory judgment that confirmed we may engage in truthfuland non-misleading speech promoting the off-label use of Vascepa to healthcare professionals, i.e., to treat patients with persistently high triglycerides, andthat such speech may not form the basis of a misbranding action under the FDCA. In August 2015, we began to communicate promotional informationbeyond the MARINE indication to healthcare professionals in the United States as permitted by this court declaration. The FDA did not appeal the court’sruling. In March 2016, we settled this litigation under terms by which the FDA and the U.S. government agreed to be bound by the conclusions from thefederal court order that we may engage in truthful and non-misleading speech promoting the off-label use of Vascepa and that certain statements anddisclosures that we proposed to make to healthcare professionals were truthful and non-misleading.While we believe we are now permitted under applicable law to more broadly promote Vascepa, the FDA-approved labeling for Vascepa did notchange as a result of this litigation and settlement, and neither government nor other third-party coverage or reimbursement to pay for the off-label use ofVascepa promoted under the court declaration was required. Based on our communications with the FDA, we expect that final positive results from theREDUCE-IT outcomes study will be required for label expansion for Vascepa.Even though we have the benefit of a final settlement in this litigation, our promotion is still subject to a high, perhaps abnormally high, degree ofscrutiny to ensure that our promotion remains within the scope covered 21Table of Contentsby the settlement. For example, under the settlement, we remain responsible for ensuring our speech is truthful and non-misleading. Federal and stategovernments may also seek to find other means to prevent our promotion of unapproved truthful and non-misleading information about Vascepa. If ourpromotional activities or other operations are found to be in violation of any of law or governmental regulation through existing or new interpretations, wemay be subject to prolonged litigation, penalties, including civil and criminal penalties, damages, fines and the curtailment or restructuring of our operations,any of which could adversely affect our ability to operate our business and our results of operations.Foreign Regulation of New Drug CompoundsIn addition to regulations in the United States, we may be subject to a variety of regulations in other jurisdictions governing, among other things,clinical trials and any commercial sales and distribution of our products.Whether or not we obtain FDA approval for a product, we must obtain the requisite approvals from regulatory authorities in all or most foreigncountries prior to the commencement of clinical trials or marketing of the product in those countries. Certain countries outside of the United States have asimilar process that requires the submission of a clinical trial application, or CTA, much like the IND prior to the commencement of human clinical trials. InEurope, for example, a CTA must be submitted to each country’s national health authority and an independent ethics committee, much like the FDA and IRB,respectively. Once the CTA is approved in accordance with a country’s requirements, clinical trial development may proceed. Similarly, clinical trialsconducted in countries such as Australia, Canada, and New Zealand, require review and approval of clinical trial proposals by an ethics committee, whichprovides a combined ethical and scientific review process. Most countries in which clinical studies are conducted require the approval of the clinical trialproposals by both the regulatory body and ethics committee.The requirements and process governing the conduct of clinical trials, product licensing, pricing and reimbursement vary from country to country. Inall cases, the clinical trials must be conducted in accordance with GCP, which have their origin in the World Medical Association’s Declaration of Helsinki,the applicable regulatory requirements, and guidelines developed by the International Conference on Harmonization, or ICH, for GCP practices in clinicaltrials.Post-Marketing RequirementsFollowing approval of a new product, a pharmaceutical company generally must engage in numerous specific monitoring and recordkeeping activities,such as routine safety surveillance, and must continue to submit periodic and other reports to the applicable regulatory agencies, including any cases ofadverse events and appropriate quality control records. Such reports submitted to the FDA may result in changes to the label and/or other post-marketingrequirements or actions, including product withdrawal. These are viable risks once a product is on the market. Additionally, modifications or enhancementsto the products or labeling or changes of site of manufacture are often subject to the approval of the FDA and other regulators, which may or may not bereceived or may result in a lengthy review process.Prescription drug advertising is subject to federal, state and foreign regulations. In the United States, the FDA regulates prescription drug promotion,including direct-to-consumer advertising. Prescription drug promotional materials must be submitted to the FDA in conjunction with their first use. Anydistribution of prescription drug products and pharmaceutical samples must comply with the U.S. Prescription Drug Marketing Act, or the PDMA, a part ofthe FDCA.In the United States, once a product is approved, its manufacture is subject to comprehensive and continuing regulation by the FDA. The FDAregulations require that products be manufactured in specific approved facilities and in accordance with pharmaceutical cGMPs, and NDA holders must listtheir products and register 22Table of Contentstheir manufacturing establishments with the FDA. These regulations also impose certain organizational, procedural and documentation requirements withrespect to manufacturing and quality assurance activities. NDA holders using contract manufacturers, laboratories or packagers are responsible for theselection and monitoring of qualified firms, and, in certain circumstances, qualified suppliers to these firms. These firms and, where applicable, their suppliersare subject to inspections by the FDA at any time, and the discovery of violative conditions, including failure to conform to cGMPs, could result inenforcement actions that interrupt the operation of any such facilities or the ability to distribute products manufactured, processed or tested by them.Federal and State Fraud and Abuse LawsIn addition to FDA restrictions on marketing of pharmaceutical products, several other types of state and federal laws restrict certain marketingpractices in the biopharmaceutical industry. These laws include anti-kickback statutes and false claims statutes.The federal anti-kickback statute prohibits, among other things, knowingly and willfully offering, paying, soliciting, or receiving remuneration toinduce or in return for a referral or the purchasing, leasing, ordering, or arranging for or recommending the purchase, lease, or order of any healthcare facility,item or service reimbursable under Medicare, Medicaid, or other federal healthcare programs. This statute has been interpreted to apply to arrangementsbetween pharmaceutical manufacturers on one hand and prescribers, purchasers, and formulary managers on the other. Liability may be established without aperson or entity having actual knowledge of the federal anti-kickback statute or specific intent to violate it. In addition, the government may assert that aclaim including items or services resulting from a violation of the federal anti-kickback statute constitutes a false or fraudulent claim for purposes of thefederal civil False Claims Act. Although there are a number of statutory exemptions and regulatory safe harbors protecting certain activities from prosecution,the exemptions and safe harbors are drawn narrowly, and practices that involve remuneration intended to induce prescribing, purchases, or recommendationsmay be subject to scrutiny if they do not qualify for an exemption or safe harbor. Moreover, there are no safe harbors for many common practices, such aseducational and research grants or patient assistance programs. Our practices may not in all cases meet all of the criteria for safe harbor protection from anti-kickback liability. The federal civil False Claims Act prohibits, among other things, any person from knowingly presenting, or causing to be presented, afalse or fraudulent claim for payment of government funds, or knowingly making or using, or causing to be made or used, a false record or statement materialto an obligation to pay money to the government or knowingly concealing, or knowingly and improperly avoiding, decreasing, or concealing an obligationto pay money to the federal government. The False Claims Act also permits a private individual acting as a “whistleblower” to bring actions on behalf of thefederal government alleging violations of the statute and to share in any monetary recovery. Recently, several pharmaceutical and other healthcarecompanies have been investigated or faced enforcement actions under the federal civil False Claims Act for a variety of alleged improper marketingactivities, including providing free product to customers with the expectation that the customers would bill federal programs for the product; providingconsulting fees, grants, free travel, and other benefits to physicians to induce them to prescribe the company’s products; or causing false claims to besubmitted because of the company’s marketing of the product for unapproved, and thus non-reimbursable, uses. Pharmaceutical and other healthcarecompanies also are subject to other federal false claims laws, including, among others, federal criminal healthcare fraud and false statement statutes thatextend to non-government health benefit programs.The Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic andClinical Health Act (HITECH), among other things, imposes criminal and civil liability for knowingly and willfully executing a scheme to defraud anyhealthcare benefit program, including private third-party payor and knowingly and willfully falsifying, concealing or covering up a material fact or makingany materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services. In addition,HITECH imposes certain requirements relating to the privacy, security and transmission of individually identifiable health information. 23Table of ContentsAs of August 1, 2013, the federal Physician Payment Sunshine Act, being implemented as the Open Payments Program, requires certain manufacturersof drugs, devices, biologics and medical supplies to engage in extensive tracking of payments and other transfers of value to physicians and teachinghospitals, including physician ownership and investment interests, and public reporting of such data. Pharmaceutical and biological manufacturers withproducts for which payment is available under Medicare, Medicaid or the State Children’s Health Insurance Program are required to have started trackingsuch payments on August 1, 2013, and must submit a report on or before the 90th day of each calendar year disclosing reportable payments made in theprevious calendar year.The majority of states also have statutes or regulations similar to the federal anti-kickback law and false claims laws, which apply to items and servicesreimbursed under Medicaid and other state programs, or, in several states, apply regardless of the payer. Sanctions under these federal and state laws mayinclude civil monetary penalties, exclusion of a manufacturer’s products from reimbursement under government programs, criminal fines, and imprisonment.There are also state laws requiring pharmaceutical companies to report gifts and other expenses relating to the marketing and promotion of pharmaceuticalproducts; prohibiting certain marketing-related activities including the provision of gifts, meals, or other items to certain healthcare providers; and/orrequiring pharmaceutical companies to implement compliance programs or marketing codes. Because of the breadth of these laws and the narrowness of theexceptions or safe harbors, it is possible that some of our business activities could be subject to challenge under one or more of such laws. Such a challengecould have a material adverse effect on our business, financial condition and results of operations. As a company marketing an FDA-approved product in theUnited States, our operations may be directly, or indirectly through our customers, subject to various federal and state fraud and abuse laws, including,without limitation, the federal anti-kickback statute. These laws may impact, among other things, our proposed sales, marketing and education programs. Inaddition, we may be subject to patient privacy regulation by both the federal government and the states in which we conduct our business.If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us, we may besubject to penalties, including civil and criminal penalties, damages, fines and the curtailment or restructuring of our operations, any of which couldadversely affect our ability to operate our business and our results of operations.In the United States and foreign jurisdictions, there have been a number of legislative and regulatory changes to the healthcare system that could affectour future results of operations. In particular, there have been and continue to be a number of initiatives at the United States federal and state levels that seekto reduce healthcare costs. The Medicare Prescription Drug, Improvement, and Modernization Act of 2003, or the MMA, imposed new requirements for thedistribution and pricing of prescription drugs for Medicare beneficiaries. Under Part D, Medicare beneficiaries may enroll in prescription drug plans offeredby private entities which will provide coverage of outpatient prescription drugs. Part D plans include both stand-alone prescription drug benefit plans andprescription drug coverage as a supplement to Medicare Advantage plans. Unlike Medicare Part A and B, Part D coverage is not standardized. Part Dprescription drug plan sponsors are not required to pay for all covered Part D drugs, and each drug plan can develop its own drug formulary that identifieswhich drugs it will cover and at what tier or level. However, Part D prescription drug formularies must include drugs within each therapeutic category andclass of covered Part D drugs, though not necessarily all the drugs in each category or class. Any formulary used by a Part D prescription drug plan must bedeveloped and reviewed by a pharmacy and therapeutic committee. Government payment for some of the costs of prescription drugs may increase demand forour products for which we receive marketing approval. However, any negotiated prices for our products covered by a Part D prescription drug plan will likelybe lower than the prices we might otherwise obtain. Moreover, while the MMA applies only to drug benefits for Medicare beneficiaries, private payers oftenfollow Medicare coverage policy and payment limitations in setting their own payment rates. Any reduction in payment that results from the MMA mayresult in a similar reduction in payments from non-governmental payers. In addition, there has been renewed interest in amending the Social Security Act toallow Medicare to negotiate prices for prescription drugs covered under Medicare Part B. If this were to be enacted by Congress and 24Table of Contentssigned by the President, the prices we obtain for our products covered under Part B could be lower than the prices we might otherwise obtain, and it couldexert a similar lowering pressure on payments from non-governmental payers.The Agency for Healthcare Research and Quality (AHRQ), established by the MMA and provided additional funding by The American Recovery andReinvestment Act of 2009, conducts comparative effectiveness research on different treatments for the same illness. Although the results of the comparativeeffectiveness studies are not intended to mandate coverage policies for public or private payers, is it possible that comparative effectiveness researchdemonstrating benefits in a competitor’s product could adversely affect the sales of our product candidates. If third-party payers do not consider our productsto be cost-effective compared to other available therapies, they may not cover our products as a benefit under their plans or, if they do, the level of paymentmay not be sufficient to allow us to sell our products on a profitable basis.In March 2010 the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, or collectively thePPACA, was enacted, which includes measures to significantly change the way healthcare is financed by both governmental and private insurers. Among theprovisions of the PPACA of greatest importance to the pharmaceutical and biotechnology industry are the following: • an annual, nondeductible fee on any entity that manufactures or imports certain branded prescription drugs and biologic products, apportionedamong these entities according to their market share in certain government healthcare programs, that began in 2011; • a licensure framework for follow-on biologic products; • a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative clinical effectiveness research,along with funding for such research; • creation of the Independent Payment Advisory Board which, beginning in 2014, will have authority to recommend certain changes to theMedicare program that could result in reduced payments for prescription drugs and those recommendations could have the effect of law even ifCongress does not act on the recommendations; and • establishment of a Center for Medicare and Medicaid Innovation at the Centers for Medicare & Medicaid Services to test innovative paymentand service delivery models to lower Medicare and Medicaid spending, potentially including prescription drug spending that began onJanuary 1, 2011.It appears likely that the PPACA will continue to exert pressure on pharmaceutical pricing, especially under the Medicare and Medicaid programs, andmay also increase our regulatory burdens and operating costs. Legislative changes to the PPACA remain possible, and appear likely in the 115th UnitedStates Congress and under the Trump Administration.Other Regulatory MattersManufacturing, sales, promotion, importation, and other activities related to approved products are also subject to regulation by numerous regulatoryauthorities, including, in the United States, the FDA, the Centers for Medicare & Medicaid Services, other divisions of the Department of Health and HumanServices, the Drug Enforcement Administration, the Consumer Product Safety Commission, the Federal Trade Commission, the Occupational Safety & HealthAdministration, the Environmental Protection Agency, and state and local governments. Sales, marketing and scientific/educational programs must complywith the Food, Drug, and Cosmetic Act, the Anti-Kickback Statute, and the False Claims Act and similar state laws. Pricing and rebate programs must complywith the Medicaid rebate requirements of the U.S. Omnibus Budget Reconciliation Act of 1990. If products are made available to authorized users of theFederal Supply Schedule of the General Services Administration, additional laws and requirements apply. Products must meet applicable child-resistantpackaging requirements under the U.S. Poison Prevention Packaging Act. 25Table of ContentsThe distribution of pharmaceutical products is subject to additional requirements and regulations, including extensive record-keeping, licensing,storage and security requirements intended to prevent the unauthorized sale of pharmaceutical products.The failure to comply with regulatory requirements subjects firms to possible legal or regulatory action. Depending on the circumstances, failure tomeet applicable regulatory requirements can result in criminal prosecution, fines or other penalties, injunctions, recall or seizure of products, total or partialsuspension of production, denial or withdrawal of product approvals, or refusal to allow a firm to enter into supply contracts, including government contracts.In addition, even if a firm complies with FDA and other requirements, new information regarding the safety or effectiveness of a product could lead the FDAto modify or withdraw a product approval. Prohibitions or restrictions on sales or withdrawal of future products marketed by us could materially affect ourbusiness in an adverse way.Changes in regulations or statutes or the interpretation of existing regulations could impact our business in the future by requiring, for example:(i) changes to our manufacturing arrangements; (ii) additions or modifications to product labeling; (iii) the recall or discontinuation of our products; or(iv) additional record-keeping requirements. If any such changes were to be imposed, they could adversely affect the operation of our business.FDA Marketing Exclusivity and Generic CompetitionThe FDCA, as amended by the Drug Price Competition and Patent Term Restoration Act of 1984, as amended, or the Hatch-Waxman Amendments,provides for market exclusivity provisions that can help protect the exclusivity of new drugs by delaying the acceptance and final approval of certaincompetitive drug applications. NCE marketing exclusivity precludes approval during the five-year exclusivity period of certain 505(b)(2) applications andabbreviated new drug applications, or ANDAs, submitted by another company for another version of the drug. However, an application may be submittedafter four years if it contains a certification of patent invalidity or non-infringement. In this case, Amarin, as a pioneer drug company, is afforded the benefit ofa 30-month stay against the launch of such a competitive product that extends from the end of the five-year exclusivity period. A pioneer company couldalso be afforded extensions to the stay under applicable regulations, including a six-month pediatric exclusivity extension or a judicial extension ifapplicable requirements are met. A drug sponsor could also gain a form of marketing exclusivity under the Hatch-Waxman Amendments if such companycan, under certain circumstances, complete a human clinical trial process and obtain regulatory approval of its product. Additional three-year periods ofexclusivity can be obtained for studies resulting in approval for new uses of existing drugs that protect the pioneer drug company from approval of ANDAapplications made with reference to the new use during the three years from approval.The FDA typically makes a determination on marketing exclusivity in connection with an NDA approval of a drug for a new indication. FDAmarketing exclusivity is separate from, and in addition to, patent protection, trade secrets and manufacturing barriers to entry, which also help protectVascepa against generic competition.We applied to the FDA for five-year, NCE marketing exclusivity for Vascepa in connection with the NDA for our MARINE indication, which NDA wasapproved by the FDA on July 26, 2012. On February 21, 2014, in connection with the July 26, 2012 approval of the MARINE indication, the FDA denied agrant of five-year NCE marketing exclusivity to Vascepa and granted three-year marketing exclusivity. Under applicable regulations, such three-yearexclusivity would have extended through July 25, 2015 and would have been supplemented by a 30-month stay triggered by patent litigation that wouldhave extended into September 2016, unless such patent litigation was resolved against us sooner.On February 27, 2014, we sued the FDA in the U.S. District Court for the District of Columbia to challenge the agency’s denial of five-year NCEexclusivity for Vascepa, based on our reading of the relevant statute, our view of FDA’s inconsistency with its past actions in this area and the retroactiveeffect of what we believe is a new policy at FDA as it relates to our situation. On May 28, 2015, the court granted our motion for summary judgment. Thedecision vacated the FDA’s denial of our claim for such exclusivity and remanded to the FDA for 26Table of Contentsproceedings consistent with the decision. On July 22, 2015, Watson Laboratories Inc., the purported first Vascepa ANDA filer, sought to intervene and appealthe court’s decision. We and FDA opposed this intervention effort. The applicable courts denied Watson the relief sought and appeal periods have expired.Based on the May 28, 2015 District of Columbia court order granting our motion for summary judgment in the NCE litigation, on June 26, 2015, theparties to the related Vascepa patent litigation that followed acceptance by FDA of ANDAs to Vascepa, based on a three-year regulatory exclusivitydetermination, agreed to a full stay of proceeding in that patent litigation.Following the May 28, 2015 District of Columbia court order setting aside FDA’s denial of NCE exclusivity for Vascepa, FDA notified the ANDA filersthat FDA had changed the status of their ANDAs to submitted, but no longer accepted, and notified ANDA filers that FDA had ceased review of the pendingANDAs. In rescinding acceptance of the ANDAs, the statutory basis for the patent litigation (accepted ANDAs) no longer existed. Thus, on July 24, 2015, wemoved to dismiss the pending patent infringement lawsuits against each of the Vascepa ANDA applicants in the U.S. District Court for the District of NewJersey.On January 22, 2016, the U.S. District Court for the District of New Jersey granted our motion to dismiss all patent infringement litigation related to the2014 acceptance by the FDA of ANDAs to Vascepa. An appeal of the court’s dismissal was filed by one ANDA filer and, after FDA’s May 2016 grant ofVascepa NCE exclusivity, that appeal was withdrawn by the ANDA filer. This dismissal and terminated appeal ended this patent litigation related to Vascepa.On May 31, 2016, in a reversal that FDA and we view as consistent with the court’s May 28, 2015 summary judgment motion, FDA determined thatVascepa is eligible for five-year, NCE marketing exclusivity. This determination provides Vascepa with the benefits of NCE exclusivity afforded by statute.NCE exclusivity for Vascepa runs from its date of FDA approval on July 26, 2012 and extends until July 26, 2017. The statutory 30-month stay triggered bypatent litigation following generic application submissions permitted on July 26, 2016 would continue until January 26, 2020, seven-and-a-half yearsfrom FDA approval, unless such patent litigation was resolved against us sooner.It is possible that FDA’s NCE determination could be challenged by interested parties. If challenged, we plan to vigorously support FDA’sdetermination. Any such challenge could have a negative impact on our company and create uncertainty around the continued benefits associated with afive-year exclusivity status.In September and October 2016, we received paragraph IV certification notices from four companies contending to varying degrees that certain of ourpatents are invalid, unenforceable and/or will not be infringed by the manufacture, use, sale or offer for sale of a generic form of Vascepa as described in thosecompanies’ ANDAs. These certifications were expected given the eligibility for submission of ANDAs under the NCE regulatory structure, after theexpiration of four years from the July 2012 approval of Vascepa.We are now in the process of defending the exclusivity of Vascepa through patent litigation against the ANDA filers. In the related lawsuits, we areseeking, among other remedies, an order enjoining filers from marketing generic versions of Vascepa before the last to expire of the asserted patents in 2030.We intend to vigorously enforce our intellectual property rights relating to Vascepa, but we cannot predict the outcome of these lawsuits or any subsequentlyfiled lawsuits.If an ANDA filer is ultimately successful in patent litigation against us, it meets the requirements for a generic version of Vascepa to the satisfaction ofthe FDA under its ANDA (after the applicable regulatory exclusivity period and the litigation-related 30-month stay period ends), and is able to supply theproduct in significant commercial quantities, the generic company could introduce a generic version of Vascepa. Such a market entry would likely limit ourU.S. sales substantially, which would have an adverse impact on our business and results of operations. In addition, even if a competitor’s effort to introduce ageneric product is ultimately unsuccessful, the perception that such development is in progress and/or news related to such progress could materially affectthe perceived value of our company and our stock price. 27Table of ContentsPatents, Proprietary Technology, Trade SecretsOur success depends in part on our ability to obtain and maintain intellectual property protection for our drug candidates, technology and know-how,and to operate without infringing the proprietary rights of others. Our ability to successfully implement our business plan and to protect our products with ourintellectual property will depend in large part on our ability to: • obtain, defend and maintain patent protection and market exclusivity for our current and future products; • preserve any trade secrets relating to our current and future products; • acquire patented or patentable products and technologies; and • operate without infringing the proprietary rights of third parties.We have prosecuted, and are currently prosecuting, multiple patent applications to protect the intellectual property developed during the Vascepadevelopment program. As of the date of this report, we had 51 patent applications in the United States that have been either issued or allowed and more than30 additional patent applications are pending in the United States. Such 51 allowed and issued applications include the following: • 2 issued U.S. patents directed to a pharmaceutical composition of Vascepa in a capsule that have terms that expire in 2020 and 2030,respectively, • 1 issued U.S. patent covering a composition containing highly pure EPA that expires in 2021, • 39 U.S. patents covering or related to the use of Vascepa in either the MARINE or ANCHOR populations that have terms that expire in 2030 orlater, • 3 additional patents related to the use of a pharmaceutical composition comprised of free fatty acids to treat the ANCHOR patient populationwith a term that expires in 2030, • 2 additional patents related to the use of a pharmaceutical composition comprised of free fatty acids to treat the MARINE patient populationwith a term that expires in 2030, • 1 additional patent related to a pharmaceutical composition comprised of free fatty acids and uses thereof to treat both the MARINE andANCHOR patient populations with a term that expires in 2030, • 1 additional patent related to a formulation of EPA/DHA and uses thereof with a term that expires in 2030, • 1 additional patent related to the use of Vascepa to treat obesity with a term that expires in 2030, and • 1 additional patent covering a pharmaceutical composition comprised of EPA and a hydroxyl compound with a term that expires in 2034.A Notice of Allowance is issued after the USPTO makes a determination that a patent can be granted from an application. A Notice of Allowance doesnot afford patent protection until the underlying patent is issued by the USPTO. No assurance can be given that applications with issued notices of allowancewill be issued as patents or that any of our pending patent applications will issue as patents. No assurance can be given that, if and when issued, our patentswill prevent competitors from competing with Vascepa. For example, we may choose to not assert all issued patents in patent litigation and patents or claimswithin patents may be determined to be invalid.We are also pursuing patent applications related to Vascepa in multiple jurisdictions outside the United States. We may be dependent in some casesupon third-party licensors to pursue filing, prosecution and maintenance of patent rights or applications owned or controlled by those parties. It is possiblethat third parties will obtain patents or other proprietary rights that might be necessary or useful to us. In cases where third parties are first to invent aparticular product or technology, or first to file after various provisions of the America Invents Act of 2011 went into effect on March 16, 2013, it is possiblethat those parties will obtain patents that will be sufficiently broad so as to prevent us from utilizing such technology or commercializing our current andfuture products. 28Table of ContentsAlthough we intend to make reasonable efforts to protect our current and future intellectual property rights and to ensure that any proprietarytechnology we acquire or develop does not infringe the rights of other parties, we may not be able to ascertain the existence of all potentially conflictingclaims. Therefore, there is a risk that third parties may make claims of infringement against our current or future products or technologies. In addition, thirdparties may be able to obtain patents that prevent the sale of our current or future products or require us to obtain a license and pay significant fees orroyalties in order to continue selling such products.We may in the future discover the existence of products that infringe patents that we own or that have been licensed to us. If we were to initiate legalproceedings against a third party to stop such an infringement, such proceedings could be costly and time consuming, regardless of the outcome. Noassurances can be given that we would prevail, and it is possible that, during such a proceeding, our patent rights could be held to be invalid, unenforceableor both. Although we intend to protect our trade secrets and proprietary know-how through confidentiality agreements with our manufacturers, employeesand consultants, we may not be able to prevent parties subject to such confidentiality agreements from breaching these agreements or third parties fromindependently developing or learning of our trade secrets.We anticipate that competitors may from time to time oppose our efforts to obtain patent protection for new technologies or to submit patentedtechnologies for regulatory approvals. Competitors may seek to oppose our patent applications to delay the approval process or to challenge our grantedpatents, for example, by requesting a reexamination of our patent at the USPTO, or by filing an opposition in a foreign patent office, even if the opposition orchallenge has little or no merit. For example, one of our patents was revoked in an opposition proceeding in Europe due to a determination of improper claimamendments under a provision of law not applicable in the United States. Such proceedings are generally highly technical, expensive, and time consuming,and there can be no assurance that such a challenge would not result in the narrowing or complete revocation of any patent of ours that was so challenged.EmployeesAt February 20, 2017, we had 215 full-time employees employed in sales, marketing, general and administrative and research and developmentfunctions.

Since we currently operate in one business segment, which is the development and commercialization of Vascepa, all required financialsegment information can be found in the consolidated financial statements. 30Table of ContentsItem 1A.Risk FactorsThis Annual Report on Form 10-K contains forward-looking information based on our current expectations. Because our actual results may differmaterially from any forward-looking statements that we make or that are made on our behalf, this section includes a discussion of important factors thatcould affect our actual future results, including, but not limited to, our ability to successfully commercialize Vascepa, our capital resources, the progressand timing of our clinical programs, the safety and efficacy of our product candidates, risks associated with regulatory filings, the potential clinicalbenefits and market potential of our product candidates, commercial market estimates, future development efforts, patent protection, effects of healthcarereform, reliance on third parties, and other risks set forth below.Risks Related to the Commercialization and Development of VascepaWe are substantially dependent upon sales of Vascepa in the United States.As a result of our reliance on a single product, Vascepa (icosapent ethyl) capsules, and our primary focus on the U.S. market in the near-term, much ofour near-term results and value as a company depends on our ability to execute our commercial strategy for Vascepa in the United States. Ifcommercialization efforts for Vascepa are not successful, our business will be materially and adversely affected.Even if we are able to successfully develop Vascepa outside the United States or develop additional products from our research and developmentefforts, the development time cycle for products typically takes several years. This restricts our ability to respond to adverse business conditions for Vascepa.If we are not successful with development, or if there is not adequate demand for Vascepa or the market for such product develops less rapidly than weanticipate, we may not have the ability to effectively shift our resources to the development of alternative products or do so in a timely manner withoutsuffering material adverse effects on our business. As a result, the lack of alternative markets and products we develop could constrain our ability to generaterevenues and achieve profitability.The uncertain effect of Vascepa on its ultimate targeted clinical benefit makes it more difficult to achieve a level of market acceptance by physicians,patients, healthcare payors and others in the medical community necessary for commercial success.In January 2013, we launched Vascepa based on FDA approval of our MARINE indication, for use as an adjunct to diet to reduce triglyceride levels inadult patients with severe (TG 500 mg/dL) hypertriglyceridemia. Approximately 4.0 million people in the United States have severely high triglyceridelevels (TG 500 mg/dL), commonly known as very high triglyceride levels. Guidelines for the management of very high triglyceride levels suggest thatreducing triglyceride levels is the primary goal in patients to reduce the risk of acute pancreatitis. A secondary goal for this patient population is to reducecardiovascular risk. The effect of Vascepa on cardiovascular mortality and morbidity, or the risk for pancreatitis, in patients with hypertriglyceridemia has notbeen determined and our FDA-approved labeling and promotional efforts state these facts.In August 2015, based on a federal court order, we also began communicating promotional information beyond the MARINE indication to healthcareprofessionals in the United States for the treatment of patients with high (TG 200 mg/dL and <500 mg/dL) triglyceride levels who are also on statin therapyfor elevated low-density lipoprotein cholesterol, or LDL-C, levels, based on results from the ANCHOR study of Vascepa. It is estimated that approximately40 million adults in the United States have high triglyceride levels (TG 200 mg/dL), and many patients with high triglycerides also have other lipid levelabnormalities such as high cholesterol and are on statin therapy. FDA did not approve Vascepa for use in this population due to the uncertain effect ofpharmaceutically induced triglyceride reduction in this patient population on cardiovascular risk reduction, the ultimate targeted clinical benefit. Ourpromotional efforts disclose this fact and what we view as truthful and non-misleading information on the current state of research on both triglyceridereduction and the active pharmaceutical ingredient, or API, in Vascepa, EPA, as each relate to the potential of Vascepa to reduce cardiovascular risk. 31®Table of ContentsThe uncertainties around the ultimate clinical benefit of Vascepa make it more difficult for Vascepa to gain market acceptance by physicians, patients,healthcare payors and others in the medical community. If Vascepa does not achieve an adequate level of acceptance, we may not generate product revenuessufficient to become profitable. The degree of market acceptance of Vascepa for the MARINE indication and in ANCHOR patients and any future approvedindications will depend on a number of factors, including: • the perceived efficacy, safety and potential advantages of Vascepa, as compared to alternative treatments; • our ability to offer Vascepa for sale at competitive prices; • convenience and ease of administration compared to alternative treatments; • the willingness of the target patient population to try new therapies and of physicians to prescribe these therapies; • the scope, effectiveness and strength of product education, marketing and distribution support, including our sales and marketing team; • publicity concerning Vascepa or competing products; • our ability to continually promote Vascepa in the United States outside of FDA-approved labeling and the related perception thereof; • sufficient third-party coverage or reimbursement for on-label use, and for permitted off-label use, the third-party coverage or reimbursement forwhich was not addressed in the scope of the August 2015 court declaration; and • the actual efficacy of the product and the prevalence and severity of any side effects, including any limitations or warnings contained inVascepa’s approved labeling.Our current and planned commercialization efforts may not be successful in increasing sales of Vascepa.Since late 2013, our sales team has consisted of approximately 150 sales professionals, including sales representatives and their managers. This salesteam promotes Vascepa to a limited group of physicians and other healthcare professionals in select geographies in the United States. This sales team is notlarge enough to call upon all physicians. In January 2013, when we initially began selling Vascepa in the United States through our own then newlyestablished sales and marketing teams and through a newly established third-party commercial distribution infrastructure, our sales team was larger. InOctober 2013, following an FDA advisory committee recommendation against approval for the ANCHOR indication, we implemented a plan to reduce ourworkforce and our team of sales professionals by half.In May 2014 we began co-promoting Vascepa in the United States with Kowa Pharmaceuticals America, Inc. under a co-promotion agreement weentered into in March 2014. Under the agreement, no less than 250 Kowa Pharmaceuticals America, Inc. sales representatives devote a substantial portion oftheir time to promoting Vascepa with our approximately 150 sales professionals, including sales representatives and their managers, based on a plan designedto focus on select sales territories that we believe have demonstrated the greatest potential for Vascepa sales growth and increase both the number of salestargets reached and the frequency of sales calls on existing sales targets. However, the commercialization of pharmaceutical products is a complexundertaking, and we have very limited experience as a company operating in this area and co-promoting a pharmaceutical product with a partner. In addition,if the results of the REDUCE-IT outcomes study are successful, we plan to expand our promotion of Vascepa, including increasing the size of our team. Wewill need to overcome challenges associated with rapidly hiring and training personnel and managing larger teams of people. Furthermore, our agreementwith Kowa Pharmaceuticals America, Inc. is designed such that their co-promotion of Vascepa ceases after 2018. If we do not extend this co-promotionagreement, enter into a co-promotion agreement with an equally capable company or hire equally capable sales representatives, our sales may be negativelyimpacted by the end of co-promotion under this agreement. 32Table of ContentsOutside of the United States, we have expanded our commercialization activities through partnering arrangements in certain territories. InFebruary 2015, we entered into a Development, Commercialization and Supply Agreement (the “DCS Agreement”) with Eddingpharm (Asia) MacaoCommercial Offshore Limited (“Eddingpharm”) related to the development and commercialization of Vascepa in Mainland China, Hong Kong, Macau andTaiwan, or the China Territory. Under the DCS Agreement, Eddingpharm is solely responsible for development and commercialization activities in the ChinaTerritory and associated expenses. Additionally, Eddingpharm is required to conduct clinical trials in the China Territory to secure regulatory approval.Significant commercialization of Vascepa in the China Territory is several years away, if at all. If Eddingpharm is not able to effectively develop andcommercialize Vascepa in the China Territory, we may not be able to generate revenue from the DCS Agreement resulting from the sale of Vascepa in theChina Territory.We have limited experience working with partners outside the United States, such as Eddingpharm, to develop and market our products in non-U.S.jurisdictions. In order for Eddingpharm, or us, to market and sell Vascepa in any country outside of the United States for any indication, it will be necessary toobtain regulatory approval from the appropriate regulatory authorities. The requirements and timing for regulatory approval, which may include conductingclinical trials, vary widely from country to country and may in some cases be different than or more rigorous than requirements in the United States. Anyfailure by us or Eddingpharm to obtain approval for Vascepa in non-U.S. jurisdictions in a timely manner may limit the commercial success of Vascepa andour ability to grow our revenues.In March 2016, we entered into an agreement with Biologix FZCo (“Biologix”), a company incorporated under the laws of United Arab Emirates, toregister and commercialize Vascepa in several Middle Eastern and North African countries. Under the terms of the distribution agreement, we granted toBiologix a non-exclusive license to use our trademarks in connection with the importation, distribution, promotion, marketing and sale of Vascepa in theMiddle East and North Africa territory. Commercialization across the region, as in China, is several years away in most jurisdictions and subject to similarrisks. We continue to assess other partnership opportunities for licensing Vascepa to partners outside of the United States.Factors related to building and managing a sales and marketing organization that can inhibit our efforts to successfully commercialize Vascepainclude: • our inability to attract and retain adequate numbers of effective sales and marketing personnel; • our inability to adequately train our sales and marketing personnel, in particular as it relates to various healthcare regulatory requirementsapplicable to the marketing and sale of pharmaceutical products and the court declaration that we believe enables us to expand marketing effortsfor Vascepa, and our inability to adequately monitor compliance with these requirements; • the inability of our new sales personnel, working for us as a new market entrant, to obtain access to or persuade adequate numbers of physiciansto prescribe Vascepa; • the lack of complementary products to be offered by sales personnel, which may put us at a competitive disadvantage relative to companies withmore extensive product lines; • an inability by us or our partners to obtain regulatory and marketing approval or establish marketing channels in foreign jurisdictions; and • unforeseen costs and expenses associated with operating a new independent sales and marketing organization.If we are not successful in our efforts to market and sell Vascepa, our anticipated revenues will be materially and negatively affected, and we may notobtain profitability, may need to cut back on research and development activities or need to raise additional funding that could result in substantial dilution. 33Table of ContentsWe expect final positive results from the REDUCE-IT outcomes study will be required for FDA-approved label expansion for Vascepa.Since January 2013, we have marketed Vascepa for use in the FDA-approved MARINE indication in the United States.In April 2015, we received a Complete Response Letter, or CRL, from the FDA on our supplemental new drug application, or sNDA, that soughtapproval for the use of Vascepa in patients with high triglyceride levels (TG 200 mg/dL and <500 mg/dL) who are also on statin therapy, which we refer toas the ANCHOR indication. In regulatory communications, the FDA acknowledged that the results of the ANCHOR trial as we presented them to FDA werevalid and truthful in that, for example, Vascepa reduced triglyceride levels compared to placebo in patients treated in the ANCHOR study. The clinicalrationale for reducing serum triglycerides with Vascepa and modifying other lipid/lipoprotein parameters shown in ANCHOR among statin-treated patientswith triglycerides 200-499 mg/dL is to reduce cardiovascular risk. In not approving our ANCHOR sNDA, the FDA concluded that, for regulatory approvalpurposes, there were insufficient data to support a drug-induced change in serum triglycerides as a surrogate for reducing cardiovascular risk in the ANCHORpopulation. The FDA did not determine that the drug-induced effects of Vascepa, which go beyond triglyceride-lowering, would not actually reducecardiovascular risk in this population.In August 2015, based on a federal court order, we began communicating promotional information beyond the MARINE indication to healthcareprofessionals in the United States through use of a set of qualified statements that reflect the state of research related to this use. In March 2016, we settled thelitigation related to this court order under terms by which the FDA and the U.S. government agreed to be bound by the conclusions from the federal courtorder that we may engage in truthful and non-misleading speech promoting the off-label use of Vascepa and that certain statements and disclosures that weproposed to make to healthcare professionals were truthful and non-misleading. An FDA-approved indication for this patient population has not beengranted. If new clinical information is demonstrated which changes what we understand today to be truthful and non-misleading, our promotion of Vascepawill need to be modified to ensure that our promotion remains truthful and non-misleading. Our ability to reach full potential in the commercialization ofVascepa in the United States is dependent upon marketing claims associated with Vascepa that are granted with the approval of an indication statement bythe FDA.Based on our communications with the FDA, we expect that final positive results from the REDUCE-IT outcomes study will be required for FDAapproval of a new indication or other label expansion for Vascepa. Any delay in obtaining, or an inability to obtain, further expansion of our marketingapproval rights with an FDA approval could prevent us from growing revenue at all or greater than our current pace and could therefore have a materialadverse effect on our operations and financial condition, including our ability to reach profitability. Even if we obtain additional regulatory approvals forVascepa, the timing or scope of any approvals may prohibit or reduce our ability to commercialize the product successfully. For example, if the approvalprocess for any expanded indication takes too long, we may miss market opportunities and give other companies the ability to develop competing productsor establish market dominance. If the FDA does not approve any expanded indication at all, it could have a material impact on our future results of operationsand financial condition. Additionally, the terms of any approvals beyond the approval received from the FDA in July 2012 for the MARINE indication mayprove to not have the scope or breadth needed for us to successfully commercialize Vascepa or become profitable.Our off-label promotion of Vascepa could subject us to additional regulatory scrutiny and present unforeseen risks.The Federal Food, Drug, and Cosmetic Act, or FDCA, has been interpreted by the FDA to make it illegal for pharmaceutical companies to promote theirFDA approved products for uses that have not been approved by the FDA. Companies that market drugs for off-label uses or indications have been subject torelated costly litigation, criminal penalties and civil liability under the FDCA and the False Claims Act. 34Table of ContentsIn May 2015, we and a group of independent physicians filed a lawsuit against the FDA seeking a federal court declaration that would permit us andour agents to promote to healthcare professionals the use of Vascepa in patients with mixed dyslipidemia and promote on the potential of Vascepa to reducethe risk of cardiovascular disease so long as the promotion is truthful and non-misleading. This use of Vascepa at issue reflects recognized medical practicebut was not approved by the FDA and is thus not covered by current FDA-approved labeling for the drug. Promotion of an off-label use is considered by theFDA to be illegal under the FDCA. The lawsuit, captioned Amarin Pharma, Inc., et al. v. Food & Drug Administration, et al., 119 F. Supp. 3d 196 (S.D.N.Y.2015), was filed in the United States District Court for the Southern District of New York. In the lawsuit, we contended principally that FDA regulationslimiting off-label promotion of truthful and non-misleading information are unconstitutional under the freedom of speech clause of the First Amendment tothe U.S. Constitution as applied in the case of our proposed promotion of Vascepa. The physicians in the suit regularly treat patients at risk of cardiovasculardisease and, as the complaint contended, have First Amendment rights to receive truthful and non-misleading information from Amarin. The suit was basedon the principle that better informed physicians make better treatment decisions for their patients. The FDA opposed this lawsuit but did not dispute theveracity of the subject ANCHOR clinical trial data, the safety data from which is already in FDA-approved labeling of Vascepa, or the peer-reviewed researchrelated to Vascepa and the potential for cardiovascular risk reduction.In connection with this litigation, the FDA sent a detailed letter to us on June 5, 2015 that confirmed the validity of the ANCHOR trial results. Theletter also sought to clarify how, in the FDA’s view, applicable law and FDA policies apply to the communications proposed in our complaint. The FDAstated in this letter that it did not have concerns with much of the information we proposed to communicate and provided us with guidance on the FDA’sview of lawful, but limited paths for the dissemination and communication to healthcare professionals of the effects of Vascepa demonstrated in theANCHOR clinical trial and use of peer-reviewed scientific publications in the context of appropriate disclaimers.In August 2015, we were granted preliminary relief in this lawsuit through the court’s declaratory judgment that confirmed we may engage in truthfuland non-misleading speech promoting the off-label use of Vascepa to healthcare professionals, i.e., to treat patients with persistently high triglycerides, andthat such speech may not form the basis of a misbranding action under the FDCA. In August 2015, we began to communicate promotional informationbeyond the MARINE indication to healthcare professionals in the United States as permitted by this court declaration. The FDA did not appeal the court’sruling. In March 2016, we settled this litigation under terms by which the FDA and the U.S. government agreed to be bound by the conclusions from thefederal court order that we may engage in truthful and non-misleading speech promoting the off-label use of Vascepa and that certain statements anddisclosures that we proposed to make to healthcare professionals were truthful and non-misleading.While we believe we are now permitted under applicable law to more broadly promote Vascepa, the FDA-approved labeling for Vascepa did notchange as a result of this litigation and settlement, and neither government nor other third-party coverage or reimbursement to pay for the off-label use ofVascepa promoted under the court declaration was required. Based on our communications with the FDA, we expect that final positive results from theREDUCE-IT outcomes study will be required for label expansion for Vascepa.Even though we have the benefit of a final settlement in this litigation, our promotion is still subject to a high, perhaps abnormally high, degree ofscrutiny to ensure that our promotion remains within the scope covered by the settlement. For example, under the settlement, we remain responsible forensuring our speech is truthful and non-misleading. Federal and state governments may also seek to find other means to prevent our promotion ofunapproved truthful and non-misleading information about Vascepa. If our promotional activities or other operations are found to be in violation of any lawor governmental regulation through existing or new interpretations, we may be subject to prolonged litigation, penalties, including civil and criminalpenalties, damages, fines and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business andour results of operations. 35Table of ContentsWe may not be able to compete effectively against our competitors’ pharmaceutical products.The biotechnology and pharmaceutical industries are highly competitive. There are many pharmaceutical companies, biotechnology companies,public and private universities and research organizations actively engaged in the research and development of products that may be similar to our products.It is probable that the number of companies seeking to develop products and therapies similar to our products will increase. Many of these and other existingor potential competitors have substantially greater financial, technical and human resources than we do and may be better equipped to develop, manufactureand market products. These companies may develop and introduce products and processes competitive with or superior to ours. In addition, othertechnologies or products may be developed that have an entirely different approach or means of accomplishing the intended purposes of our products, whichmight render our technology and products noncompetitive or obsolete.Our competitors both in the United States and Europe include large, well-established pharmaceutical companies, specialty pharmaceutical sales andmarketing companies, and specialized cardiovascular treatment companies. GlaxoSmithKline plc, which currently sells Lovaza, a prescription-only omega-3fatty acid indicated for patients with severe hypertriglyceridemia was approved by FDA in 2004 and has been on the market in the United States since 2005.As described below, multiple generic versions of Lovaza are now available in the United States. Other large companies with competitive products includeAbbVie, Inc., which currently sells Tricor and Trilipix for the treatment of severe hypertriglyceridemia and Niaspan, which is primarily used to raiseHDL-C but is also used to lower triglycerides. Generic versions of Tricor, Trilipix, and Niaspan are also now available in the United States. In addition, inMay 2014, Epanova (omega-3-carboxylic acids) capsules, a free fatty acid form of omega-3 (comprised of 55% EPA and 20% DHA), was approved by theFDA for patients with severe hypertriglyceridemia. Epanova was developed by Omthera Pharmaceuticals, Inc., and is now owned by AstraZenecaPharmaceuticals LP (AstraZeneca). Also, in April 2014, Omtryg, another omega-3-acid fatty acid composition developed by Trygg Pharma AS, received FDAapproval for severe hypertriglyceridemia. Neither Epanova nor Omtryg have been commercially launched, but could launch at any time. Each of thesecompetitors, other than potentially Trygg, has greater resources than we do, including financial, product development, marketing, personnel and otherresources.Currently, six manufacturers have launched generic versions of Lovaza. In April 2014, Teva Pharmaceuticals USA Inc., or Teva, launched a genericversion of Lovaza after winning its patent litigation against Pronova BioPharma Norge AS, now owned by BASF, which owns such patent rights. In June2014 and September 2014, Par Pharmaceutical Inc., or Par, and Apotex Inc., or Apotex, respectively, received FDA approval of their respective versions ofgeneric Lovaza. Par launched a generic version of Lovaza in July 2014. In March 2011, Pronova/BASF entered into an agreement with Apotex to settle itspatent litigation in the United States related to Lovaza. Pursuant to the terms of the settlement agreement, Apotex launched a generic version of Lovaza inJanuary 2015. Prasco Labs launched a generic version of Lovaza in March 2015 and AvKARE, Inc., or AvKARE, launched its version in May 2015. AvKAREsupplies government agencies and does not participate in the commercial marketplace. Amneal Pharmaceuticals launched a generic version of Lovaza inJanuary 2016. In December 2016, Golden State Medical Supply launched a generic version of Lovaza. Like AvKARE, Golden State Medical Supply onlysupplies products to government agencies and does not participate in the commercial marketplace.In addition, we are aware of other pharmaceutical companies that are developing products that, if approved and marketed, would compete withVascepa. We understand that Acasti Pharma, or Acasti, a subsidiary of Neptune Technologies & Bioresources Inc., announced in December 2015 that itintends to pursue a regulatory pathway under section 505(b)(2) of the FDCA for its omega-3 prescription drug candidate, CaPre, derived from krill oil, forthe treatment of hypertriglyceridemia. In September 2016, Acasti announced positive results from its pivotal bioavailability bridging study comparing CaPreto Lovaza, establishing a scientific bridge between the two that is expected to support the feasibility of a 505(b)(2) regulatory pathway. Acasti intends tocomplete long-term toxicity studies in the next 6-9 months and follow these with a Phase 3 clinical program to assess the safety and efficacy of CaPre inpatients with very high (500 mg/dL) triglycerides. We believe Sancilio & Company, or 36®®®®®®Table of ContentsSancilio, is also developing potential treatments for hypertriglyceridemia based on omega-3 fatty acids. To our knowledge, Sancilio is pursuing a regulatorypathway under section 505(b)(2) of the FDCA for its product and submitted an Investigational New Drug Application, or IND, in July 2015. Sanciliocompleted two pharmacokinetic studies and Phase 2 bioavailability studies (FASTR I&II), with one comparing SC401 to Lovaza. We expect the company toinitiate a pivotal clinical Phase 3 study as the next step in development.In addition, we are aware that Matinas BioPharma, Inc. is developing an omega-3-based therapeutic for the treatment of severe hypertriglyceridemiaand mixed dyslipidemia. Matinas BioPharma, Inc. has filed an IND with the FDA to conduct a human study in the treatment of severe hypertriglyceridemia.Akcea Therapeutics/Ionis Pharmaceuticals (formerly Isis Pharmaceuticals), or Akcea/Ionis, announced favorable Phase 3 results of volanesorsen (formerlyISIS-APOCIII), a drug candidate administered through weekly subcutaneous injections, in patients with severe hypertriglyceridemia (COMPASS trial).Phase 2 trials are currently ongoing studying volanesorsen in patients with familial chylomicronemia syndrome (FCS) and familial partial lipodystrophy(FPL) with data expected in 2017 and 2019. In January 2017, Akcea/Ionis announced a strategic collaboration and option agreement with Novartis wherebyNovartis will help develop (including funding cardiovascular outcomes studies) and commercialize products emerging from this collaboration, includingvolanesorsen. Madrigal Pharmaceuticals has completed Phase 1 clinical testing of MGL-3196 for the treatment of high triglycerides and various lipidparameters in patients. Finally, Gemfire Therapeutics announced favorable results from a Phase 2 trial to evaluate the safety and efficacy of gemcabene, anoral, once-daily pill, in the treatment of patients with homozygous familial hypercholesterolemia (HoFH) on stable lipid-lowering therapy. The novelmechanism of action of gemcabene may support multiple indications including a potential severe triglyceride reduction. Three Phase 2b trials of gemcabeneare ongoing in patients with HoFH on stable lipid-lowering therapy, in patients with severe hypertriglyceridemia, and in patients with hypercholesterolemiaon a high-intensity stable statin therapy with or without ezetimibe.Generic company competitors are seeking FDA approval of generic versions of Vascepa and we are now engaged in related patent litigation.The FDCA, as amended by the Drug Price Competition and Patent Term Restoration Act of 1984, as amended, or the Hatch-Waxman Amendments,permits the FDA to approve ANDAs for generic versions of brand name drugs like Vascepa. We refer to the process of generic drug applications as the “ANDAprocess.” The ANDA process permits competitor companies to obtain marketing approval for a drug product with the same active ingredient, dosage form,strength, route of administration, and labeling as the approved brand name drug, but without having to conduct and submit clinical studies to establish thesafety and efficacy of the proposed generic product. In place of such clinical studies, an ANDA applicant needs to submit data demonstrating that its productis bioequivalent to the brand name product, usually based on pharmacokinetic studies.The Hatch-Waxman Amendments require an applicant for a drug product that relies, in whole or in part, on the FDA’s prior approval of Vascepa, tonotify us of its application, a “paragraph IV” notice, if the applicant is seeking to market its product prior to the expiration of the patents that claim Vascepa.A bona fide paragraph IV notice may not be given under the Hatch-Waxman Amendments until after the generic company receives from the FDA anacknowledgement letter stating that its ANDA is sufficiently complete to permit a substantive review.The paragraph IV notice is required to contain a detailed factual and legal statement explaining the basis for the applicant’s opinion that the proposedproduct does not infringe our patents, that our patents are invalid, or both. After receipt of a valid notice, we would have the option of bringing a patentinfringement suit in federal district court against any generic company seeking approval for its product within 45 days from the date of receipt of each notice.If such a suit is commenced within this 45 day period, we will be entitled to receive a 30 month stay on FDA’s ability to give final approval to any of theproposed products that reference Vascepa that begins on the date we receive the paragraph IV notice. The stay may be shortened or lengthened if either partyfails to cooperate in the litigation and it may be terminated if the court decides the case in less than 30 months. If the litigation is resolved in favor of theapplicant before the expiration of the 30 month period, the stay will be 37RxTable of Contentsimmediately lifted and the FDA’s review of the application may be completed. Such litigation is often time-consuming and costly, and may result in genericcompetition if such patents are not upheld or if the generic competitor is found not to infringe such patents.In the first half of 2014, we received six paragraph IV notices notifying us of accepted ANDAs to Vascepa under the Hatch-Waxman Amendments.These ANDAs were submitted and accepted by FDA under the regulatory scheme adopted under the Hatch-Waxman Amendments based on the FDA’sdetermination that we were entitled to three, and not five-year exclusivity. As a result from the first half of 2014 until June 2015, we were engaged in costlylitigation with the ANDA applicants to protect our patent rights.Based on the May 28, 2015, District of Columbia court order granting our motion for summary judgment in the NCE litigation, on June 26, 2015, theparties to the related Vascepa patent litigation that followed acceptance by FDA of ANDAs to Vascepa based on a three-year regulatory exclusivitydetermination, agreed to a full stay of proceeding in that patent litigation.Following the May 28, 2015 District of Columbia court order setting aside FDA’s denial of NCE exclusivity for Vascepa, FDA notified the ANDA filersthat FDA had changed the status of their ANDAs to submitted, but no longer accepted, and notified ANDA filers that FDA had ceased review of the pendingANDAs. In rescinding acceptance of the ANDAs, the statutory basis for the patent litigation (accepted ANDAs) no longer existed. Thus, on July 24, 2015, wemoved to dismiss the pending patent infringement lawsuits against each of the Vascepa ANDA applicants in the U.S. District Court for the District of NewJersey.On January 22, 2016, the U.S. District Court for the District of New Jersey granted our motion to dismiss all patent infringement litigation related to the2014 acceptance by the FDA of ANDAs to Vascepa. An appeal of the court’s dismissal was filed by one ANDA filer and, after FDA’s May 2016 grant ofVascepa NCE exclusivity, that appeal was withdrawn by the ANDA filer. This dismissal and terminated appeal ended this patent litigation related to Vascepa.On May 31, 2016, in a reversal that FDA and we view as consistent with the court’s May 28, 2015 summary judgment motion, FDA determined thatVascepa is eligible for five-year, NCE marketing exclusivity. This determination provides Vascepa with the benefits of NCE exclusivity afforded by statute.NCE exclusivity for Vascepa runs from its date of FDA approval on July 26, 2012 and extends until July 26, 2017. The statutory 30-month stay triggered bypatent litigation following generic application submissions permitted on July 26, 2016 would continue until January 26, 2020, seven-and-a-half yearsfrom FDA approval, unless such patent litigation was resolved against us sooner.It is possible that FDA’s NCE determination could be challenged by interested parties. If challenged, we plan to vigorously support FDA’sdetermination. Any such challenge could have a negative impact on our company and create uncertainty around the continued benefits associated with afive-year exclusivity status.In September and October 2016, we received paragraph IV certification notices from four companies contending to varying degrees that certain of ourpatents are invalid, unenforceable and/or will not be infringed by the manufacture, use, sale or offer for sale of a generic form of Vascepa as described in thosecompanies’ ANDAs. These certifications were expected given the eligibility for submission of ANDAs under the NCE regulatory structure, after theexpiration of four years from the July 2012 approval of Vascepa.We filed patent infringement lawsuits against three of these four ANDA applicants. In October 2016, Amarin filed a lawsuit against RoxaneLaboratories, Inc. and related parties (collectively, “Roxane”) in the U.S. District Court for the District of Nevada. The case against Roxane iscaptioned Amarin Pharma, Inc. et al. v. Roxane Laboratories, Inc. et al., Civ. A. No. 2:16-cv-02525 (D. Nev.). In November 2016, Amarin filed a lawsuitagainst Dr. Reddy’s Laboratories, Inc. and Dr. Reddy’s Laboratories, Ltd. (collectively, “DRL”) in the U.S. District Court for the District of Nevada. The caseagainst DRL is captioned Amarin Pharma, Inc. et al. v. Dr. Reddy’s Laboratories, Inc. et al., Civ. A. No. 2:16-cv-02562 (D. Nev.). In November 2016, Amarinfiled a lawsuit against Teva Pharmaceuticals USA, Inc. and Teva Pharmaceuticals Industries Limited (collectively, 38Table of Contents“Teva”) in the U.S. District Court for the District of Nevada. The case against Teva is captioned Amarin Pharma, Inc. et al. v. Teva Pharmaceuticals USA, Inc.et al., Civ. A. No. 2:16-cv-02658. In all three lawsuits, we are seeking, among other remedies, an order enjoining each defendant from marketing genericversions of Vascepa before the last to expire of the asserted patents in 2030. The three lawsuits have been consolidated for pretrial proceedings, and are intheir early stages. As a result of the statutory stay associated with the filing of these lawsuits under the Hatch-Waxman Act, the FDA cannot grant finalapproval to Roxane, DRL, or Teva’s respective ANDA before January 2020, unless there is an earlier court decision holding that the subject patents are notinfringed and/or are invalid.The fourth ANDA applicant referenced above is Apotex Inc. (“Apotex”), which sent Amarin a paragraph IV certification notice in September 2016. Thenotice reflected that Apotex made a paragraph IV notice as to some, but not all, of the patents listed in the Orange Book for Vascepa. Because Apotex did notmake a paragraph IV certification as to all listed patents, Apotex cannot market a generic version of Vascepa before the last to expire of the patents for whichApotex did not make a paragraph IV certification, which is in 2030. At a later date, Apotex may elect to amend its ANDA in order to make a paragraph IVcertification as to additional listed patents. If and when Apotex does make such an amendment, it would be required to send Amarin an additional paragraphIV certification notice, and Amarin would then have the ability to file a lawsuit against Apotex pursuant to the Hatch-Waxman Act.We intend to vigorously enforce our intellectual property rights relating to Vascepa, but we cannot predict the outcome of the Roxane, DRL orTeva lawsuits or any subsequently filed lawsuits.If an ANDA filer is ultimately successful in patent litigation against us, it meets the requirements for a generic version of Vascepa to the satisfaction ofthe FDA under its ANDA (after the applicable regulatory exclusivity period and the litigation-related 30-month stay period ends), and is able to supply theproduct in significant commercial quantities, the generic company could introduce a generic version of Vascepa. Such a market entry would likely limit ourU.S. sales, which would have an adverse impact on our business and results of operations. In addition, even if a competitor’s effort to introduce a genericproduct is ultimately unsuccessful, the perception that such development is in progress and/or news related to such progress could materially affect theperceived value of our company and our stock price.Vascepa’s five-year, new chemical entity, or NCE, regulatory exclusivity from the FDA and related 30-month stay that is scheduled to expire in January2020 could be challenged by companies seeking to make generic versions of Vascepa.The timelines and conditions under the abbreviated new drug application, or ANDA, process that permit the start of patent litigation and allow the FDAto approve generic versions of brand name drugs like Vascepa differ based on whether a drug receives three-year, or five-year, new chemical entity, or NCE,marketing exclusivity. In May 2016, after significant litigation, FDA determined that Vascepa is eligible for NCE marketing exclusivity. Accordingly, arelated 30-month stay is currently in place and is scheduled to continue until January 26, 2020, seven-and-a-half years from FDA approval of Vascepa, unlessrelated patent litigation is resolved against us sooner.The FDA typically makes a determination on marketing exclusivity in connection with an NDA approval of a drug for a new indication. FDAmarketing exclusivity is separate from, and in addition to, patent protection, trade secrets and manufacturing barriers to entry which also help protect Vascepaagainst generic competition.We applied to the FDA for five-year, NCE marketing exclusivity for Vascepa in connection with the NDA for our MARINE indication, which NDA wasapproved by the FDA on July 26, 2012. On February 21, 2014, in connection with the July 26, 2012 approval of the MARINE indication, the FDA denied agrant of five-year NCE marketing exclusivity to Vascepa and granted three-year marketing exclusivity. Under applicable regulations, such three-yearexclusivity would have extended through July 25, 2015 and would have been supplemented by a 30-month stay triggered by patent litigation that wouldhave extended into September 2016, unless such patent litigation was resolved against us sooner. 39Table of ContentsNCE marketing exclusivity precludes approval during the five-year exclusivity period of certain 505(b)(2) applications and ANDAs submitted byanother company for another version of the drug. However, an application may be submitted after four years if it contains a certification of patent invalidityor non-infringement. In this case, Amarin, as a pioneer drug company, is afforded the benefit of a 30-month stay against the launch of such a competitiveproduct that extends from the end of the five-year exclusivity period. A pioneer company could also be afforded extensions to the stay under applicableregulations, including a six-month pediatric exclusivity extension or a judicial extension if applicable requirements are met. A drug sponsor could also gaina form of marketing exclusivity under the Hatch-Waxman Amendments if such company can, under certain circumstances, complete a human clinical trialprocess and obtain regulatory approval of its product.In contrast, a three-year period of exclusivity under the Hatch-Waxman Amendments is generally granted for a drug product that contains an activemoiety that has been previously approved, such as when the application contains reports of new clinical investigations (other than bioavailability studies)conducted by the sponsor that were essential to approval of the application. Accordingly, we expect to receive three-year exclusivity in connection with anyfuture regulatory approvals of Vascepa, such as an approval sought based on positive REDUCE-IT outcomes study results. Such three-year exclusivityprotection precludes the FDA from approving a marketing application for an ANDA, a product candidate that the FDA views as having the same conditions ofapproval as Vascepa (for example, the same indication and/or other conditions of use), or a 505(b)(2) NDA submitted to the FDA with Vascepa as thereference product, for a period of three years from the date of FDA approval. The FDA may accept and commence review of such applications during thethree-year exclusivity period. Such three-year exclusivity grant does not prevent a company from challenging the validity of patents at any time, subject toany prior four-year period pending from a grant of five-year exclusivity. This three-year form of exclusivity may also not prevent the FDA from approving anNDA that relies only on its own data to support the change or innovation.On February 27, 2014, we sued the FDA in the U.S. District Court for the District of Columbia to challenge the agency’s denial of five-year NCEexclusivity for Vascepa, based on our reading of the relevant statute, our view of FDA’s inconsistency with its past actions in this area and the retroactiveeffect of what we believe is a new policy at FDA as it relates to our situation. On May 28, 2015, the court granted our motion for summary judgment. Thedecision vacated the FDA’s denial of our claim for such exclusivity and remanded to the FDA for proceedings consistent with the decision. On July 22, 2015,Watson Laboratories Inc., the purported first Vascepa ANDA filer, sought to intervene and appeal the court’s decision. We and FDA opposed this interventioneffort. The applicable courts denied Watson the relief sought and appeal periods have expired.On May 31, 2016, in a reversal that FDA and we view as consistent with the court’s May 28, 2015 summary judgment motion, FDA determined thatVascepa is eligible for five-year, NCE marketing exclusivity. This determination provides Vascepa with the benefits of NCE exclusivity afforded by statute.NCE exclusivity for Vascepa runs from its date of FDA approval on July 26, 2012 and extends until July 26, 2017. The statutory 30-month stay triggered bypatent litigation following generic application submissions permitted on July 26, 2016 would continue until January 26, 2020, seven-and-a-half yearsfrom FDA approval, unless such patent litigation was resolved against us sooner.It is possible that FDA’s NCE determination could be challenged by interested parties. If challenged, we plan to vigorously support FDA’sdetermination. Any such challenge could have a negative impact on our company and create uncertainty around the continued benefits associated with afive-year, NCE exclusivity status.Vascepa is a prescription-only omega-3 fatty acid product. Omega-3 fatty acids are also marketed by other companies as non-prescription dietarysupplements. As a result, Vascepa is subject to non-prescription competition and consumer substitution.Our only product, Vascepa, is a prescription-only omega-3 fatty acid in ethyl ester form. Mixtures of omega-3 fatty acids in triglyceride form arenaturally occurring substances contained in various foods, including 40Table of Contentsfatty fish. Omega-3 fatty acids are also marketed by others as non-prescription dietary supplements. We cannot be sure physicians will view thepharmaceutical grade purity and tested efficacy and safety of Vascepa as having a superior therapeutic profile to untested and largely unregulated omega-3fatty acid dietary supplements. In addition, the FDA has not enforced what we view as illegal drug claims made by certain omega-3 fatty acid supplementmanufacturers to the extent we believe appropriate under applicable law and regulations, for example, claims that such supplements reduce triglyceridelevels. Also, for more than a decade now, the FDA has expressly permitted dietary supplement manufacturers that sell supplements containing the omega-3fatty acids EPA and/or DHA to make the following qualified health claim directly to consumers: Supportive but not conclusive research shows thatconsumption of EPA and DHA omega-3 fatty acids may reduce the risk of coronary heart disease. As a result of our First Amendment litigation andsettlement, we may now make this claim to healthcare professionals subject to certain qualifications. These factors enable dietary supplements to effectivelycompete with Vascepa. In addition, to the extent the net price of Vascepa after insurance and offered discounts is significantly higher than the prices ofcommercially available omega-3 fatty acids marketed by other companies as dietary supplements (through that lack of coverage by insurers or otherwise),physicians and pharmacists may recommend these commercial alternatives instead of writing or filling prescriptions for Vascepa or patients may elect ontheir own to take commercially available omega-3 fatty acids. While Vascepa is highly price-competitive for patients when covered by insurance—cheaper inmany cases—either of these outcomes may adversely impact our results of operations by limiting how we price our product and limiting the revenue wereceive from the sale of Vascepa due to reduced market acceptance.We may not be successful in our Vascepa co-promotion effort with Kowa Pharmaceuticals America, Inc.In March 2014, we entered into a co-promotion agreement with Kowa Pharmaceuticals America, Inc. to co-promote Vascepa in the United States underwhich no less than 250 Kowa Pharmaceuticals America, Inc. sales representatives devote a substantial portion of their time to promoting Vascepa with ourapproximately 150 sales professionals, including sales representatives and their managers. Co-promotion under the agreement commenced in May 2014based on a plan designed to substantially increase both the number of sales targets reached and the frequency of sales calls on existing sales targets. Whileour agreement provides for minimum performance criteria, we have little control over Kowa Pharmaceuticals America, Inc., and it may fail to devote thenecessary resources and attention to promote Vascepa effectively. If that were to occur, depending on Vascepa revenues, we may have to curtail the continueddevelopment of Vascepa for approval for additional indications or increase our planned expenditures and undertake additional development orcommercialization activities at our own expense. Or, we may seek to terminate the agreement and search for another commercialization partner. If we elect toincrease our expenditures to fund development or commercialization activities on our own, depending on Vascepa’s revenues, we may need to obtainadditional capital, which may not be available to us on acceptable terms, or at all, or which may not be possible due to our other financing arrangements. Ifwe do not generate sufficient funds from the sale of Vascepa or, to the extent needed to supplement funds generated from product revenue, cannot raisesufficient funds, we may not be able to devote resources sufficient to market and sell Vascepa on our own in a manner required to realize the full marketpotential of Vascepa.The commercial value to us of current and sought marketing rights may be smaller than we anticipate.There can be no assurance as to the adequacy for commercial success of the scope and breadth of the marketing rights we currently have or, if approved,an indication based on a successful outcome of the REDUCE-IT study. Even if we obtain marketing approval for additional indications, the FDA may imposerestrictions on the product’s conditions for use, distribution or marketing and in some cases may impose ongoing requirements for post-market surveillance,post-approval studies or clinical trials. Also, the number of actual patients with conditions within the scope of our marketing efforts may be smaller than weanticipate. If any such marketing right or approved indication is narrower than we anticipate, the market potential for our product would suffer. 41Table of ContentsOur special protocol assessment, or SPA, agreement for ANCHOR was rescinded and our SPA agreement for REDUCE-IT is not a guarantee of FDAapproval of Vascepa for the proposed REDUCE-IT indication.A SPA is an evaluation by the FDA of a protocol with the goal of reaching an agreement that the Phase 3 trial protocol design, clinical endpoints, andstatistical analyses are acceptable to support regulatory approval of the drug product candidate with respect to effectiveness for the indication studied. TheANCHOR trial was, and the REDUCE-IT trial is, being conducted under a SPA agreement with the FDA. In each case, the FDA agreed that, based on theinformation we submitted to the agency, the design and planned analysis of the trial is adequate to support use of the conducted study as the primary basis forapproval with respect to effectiveness. A SPA agreement is not a guarantee of approval. A SPA agreement is generally binding upon the FDA except inlimited circumstances, such as if the FDA identifies a substantial scientific issue essential to determining safety or efficacy after the study begins, or if thestudy sponsor fails to follow the protocol that was agreed upon with the FDA. The FDA reserves the right of final determinations for approval based on itsreview of the entire data presented in a marketing application.In October 2013, the FDA notified us that it rescinded the ANCHOR study SPA agreement because the FDA determined that a substantial scientificissue essential to determining the effectiveness of Vascepa in the studied population was identified after testing began. In April 2015, we received a CRLfrom the FDA stating that the FDA determined not to approve label expansion reflecting the ANCHOR clinical trial efficacy data at this time.Thus, even though we have received regulatory approval of Vascepa for the MARINE indication under a SPA agreement, our ANCHOR SPA agreementwas rescinded. There is no assurance that the FDA will not rescind our REDUCE-IT SPA agreement.In August 2016, we announced an amendment to our REDUCE-IT SPA agreement with FDA that reaffirmed FDA concurrence on key elements of thestudy, defined details of the statistical analysis plan for the study, expanded to greater than 30 the pre-specified secondary and tertiary endpoints in the study,and added a second interim efficacy and safety analysis by the independent data monitoring committee (DMC) at approximately 80% of the target aggregatenumber of primary cardiovascular events. In this amended REDUCE-IT SPA agreement, FDA agreed that, based on the information submitted to the agency,the critical elements of the revised REDUCE-IT protocol and analysis plans adequately address the objectives necessary to support a regulatory submission.However, secondary and/or tertiary endpoints, their ordering in the statistical hierarchy, their clinical significance, or whether any would yield resultsappropriate for labeling are considered review issues and are not intended to be a binding component of the REDUCE-IT SPA agreement. Further, matterssuch as endpoint adjudication procedures (including potential endpoint ascertainment, adjudication process, and detailed definitions) were specified by FDAas issues to be reviewed by the agency as part of a drug approval application. Consistent with the May 2016 FDA SPA draft guidance, FDA stated that theSPA agreement does not necessarily indicate the agency’s agreement with every detail of a protocol; instead, such an agreement indicates FDA’s concurrencewith the elements critical to ensuring that the trial conducted under the protocol would have the potential to form the primary basis of an efficacy claim in amarketing application. In September 2016, we announced that the DMC completed its review of the first pre-specified interim efficacy analysis and,consistent with previously stated expectations, recommended that the trial continue as planned without modification.The inability to obtain marketing approval in the ANCHOR or REDUCE-IT indications has prevented, and would continue to prevent, us from growingrevenue more significantly, and it has had, and could continue to have, a material adverse effect on our operations and financial condition, including ourability to reach profitability. 42Table of ContentsThe REDUCE-IT cardiovascular outcomes trial may fail to show that Vascepa can reduce major cardiovascular events in an at-risk patient populationon statin therapy, and the long-term clinical results of Vascepa may not be consistent with the clinical results we observed in our Phase 3 clinical trial,in which case our sales of Vascepa may then suffer.In accordance with the SPA agreements for our MARINE and ANCHOR trials, efficacy was evaluated in these trials compared to placebo at twelveweeks. No placebo-controlled studies have been conducted regarding the long-term effect of Vascepa on lipids, and no outcomes study has been conductedevaluating Vascepa. The REDUCE-IT study, which commenced in 2011 and completed patient enrollment and randomization of 8,175 individual patients in2016, is designed to evaluate the efficacy of Vascepa in reducing major cardiovascular events in an at-risk patient population with high triglyceride levelsdespite being on statin therapy.Outcomes studies of certain other lipid-modifying therapies have failed to achieve the endpoints of such studies, even though they reducedtriglyceride levels and showed other favorable effects on parameters relevant to cardiovascular health in studied patients. For example, in 2010, the results ofthe ACCORD-Lipid trial were published. This trial studied the effect of adding fenofibrate onto open-label simvastatin therapy on cardiovascular outcomes.The addition of fenofibrate did not show any treatment benefit on cardiovascular outcomes over simvastatin monotherapy in this study. In 2011, the resultsof the AIM-HIGH trial were published. This trial studied the effect of adding a second lipid-altering agent, extended-release niacin, to simvastatin therapy oncardiovascular outcomes in people at high risk for cardiovascular events. No significant incremental treatment benefit with extended-release niacin wasobserved.Outcomes studies of certain other lipid-modifying therapies included results which, after review of information not fully available to the sponsorsduring the conduct of the trials, modified initial reports of the trial results. Two examples are the AIM-HIGH trial and the IMPROVE-IT trial. When theAIM-HIGH trial was stopped, there were initial reports of certain safety concerns which, upon further and more detailed subsequent review, were concluded tonot be associated with the study therapy. After the IMPROVE-IT trial was completed, initial reports on the effect of adding ezetimibe to statin therapy insubjects with acute coronary syndrome suggested greater benefit on cardiovascular outcomes than was considered to be the case after later reassessment andfurther evaluation of study data. In 2015, the results of the IMPROVE-IT trial were published. Based on the published results, the addition of ezetimibeshowed incremental lowering of LDL cholesterol levels and improved cardiovascular outcomes. This result was statistically significant but less than tenpercent. Further evaluation of the IMPROVE-IT results suggested that the outcomes benefit may have been lower after factoring in and making certainassumptions regarding complicating factors such as a high number of patients who discontinued the study drug, withdrew consent, or were lost to follow-up.FDA approval of a new indication for ezetimibe based on the IMPROVE-IT results was denied after a negative FDA advisory committee recommendation thatfollowed examination of the study results.In addition, in September 2012, researchers published in the Journal of the American Medical Association, or JAMA, the results of a retrospectivemeta-analysis of twenty previously conducted studies regarding the use of omega-3 supplements across various patient populations. This meta-analysissuggested that the use of such supplements was not associated with a lower risk of all-cause death, cardiac death, sudden death, heart attack, or stroke. Thesefacts illustrate categories of challenges faced in demonstrating favorable results in complex clinical studies like REDUCE-IT and in seeking to apply thoseresults in support of regulatory approvals.Data from clinical trials are invariably complex. It is also not typically possible to reliably extrapolate results from one trial to predict results fromanother. For instance, the outcomes studies for fenofibrates and niacin were conducted in patient populations in which the majority of patients studied hadtriglycerides below 200 mg/dL and fenofibrates and niacin are believed to work differently than Vascepa in the body and do not have as favorable a side-effect profile, and nineteen of the twenty studies included in the JAMA meta-analysis involved the use of omega-3 supplements containing a mixture of EPAand DHA, and most were evaluated at relatively lower doses. In addition, in May 2013, The New England Journal of Medicine published the results of anoutcomes study of 1 gram per day of an omega-3 acid ethyl ester composition. In that study, the composition 43Table of Contentsfailed to show a benefit in reducing the rate of death from cardiovascular causes or hospitalization for cardiovascular causes when administered to patientswith cardiovascular risk factors under different study conditions than in the REDUCE-IT study. Vascepa is comprised of highly-pure ethyl-EPA, and has beenapproved by the FDA for use in adult patients with severe hypertriglyceridemia at a dose of 4 grams per day and is being studied in REDUCE-IT at 4 gramsper day.The only other outcomes study involving the use of a highly-pure formulation of ethyl-EPA, called the Japan EPA Lipid Intervention Study (JELIS),suggested that use of a highly-pure formulation of ethyl-EPA in Japan, when used in conjunction with statins, reduced cardiovascular events by 19%compared to the use of statins alone. However, there are several limitations to the JELIS study. First, the patient population was exclusively Japanese, themajority of the participants were women, and at baseline patients had a much higher LDL, limiting its generalizability to the intended target population.Also, a low dose of statins was used. It is unknown whether the positive treatment effects would have persisted if these patients had been optimally treatedwith statins using contemporary LDL targets in the United States. In addition, JELIS was an open-label trial, which could influence patient and physicianbehavior and reporting of symptoms, decisions regarding hospitalization, and referral of events for adjudication. This may be particularly relevant sincehospitalization for unstable angina was a primary contributor of the overall positive result, and is considered a softer endpoint than fatal cardiovascularevents.Further, FDA determined that JELIS results could not be used as support for or against the use of triglyceride levels as a surrogate for cardiovascularrisk reduction. Patients treated with EPA and statin in JELIS achieved triglyceride levels that were only 5% lower, on average, than those achieved amongpatients treated with statin alone; however, the reduction in cardiovascular risk in the primary endpoint analysis was 19%. Likewise, within the primary andsecondary prevention sub-analyses, triglyceride levels were lowered only 5% on average in the EPA plus statin group compared with the statin alone group;however, the relative risk reduction was 53% in the primary prevention population with elevated triglyceride (150 mg/dL) and low HDL-C (£40 mg/dL)levels and 23% in the secondary prevention population with established coronary artery disease. These large differences in magnitude between triglyceridereduction and risk reduction in JELIS suggest that the effects of EPA on triglyceride levels alone may not be responsible for, or predict, the observeddifferences in cardiovascular events between treatment groups in JELIS. JELIS was not designed to evaluate primary and secondary prevention populations.It is possible that the putative cardioprotective effects of EPA observed in JELIS are due not to a single mode of action, such as triglyceride lowering, butrather to multiple mechanisms working together, such as purported beneficial effects on multiple atherosclerosis processes, including endothelial function,oxidative stress, foam cell formation, inflammation/cytokines, plaque formation/progression, platelet aggregation, thrombus formation, and plaque rupture.The REDUCE-IT study is needed to determine the clinical benefit, if any, of EPA therapy in statin-treated patients with elevated triglyceride levels.There can be no assurance that the REDUCE-IT study will be completed successfully, that the endpoints of the REDUCE-IT cardiovascular outcomesstudy will be achieved, that the results will support regulatory approvals, or that the lipid-modifying effects of Vascepa in REDUCE-IT or any other study ofVascepa will not be subject to variation beyond twelve weeks. If the REDUCE-IT trial is not successful or if the results of this long-term study are notconsistent with the 12-week clinical results, it could prevent us from expanding the labeled approval of Vascepa or even call into question the currentlyunderstood efficacy and safety profile of Vascepa. In any such case, the market potential for Vascepa would suffer and our business would be materiallyaffected.The commercial value to us of sales of Vascepa outside the United States, such as under the DCS Agreement with Eddingpharm, may be smaller than weanticipate.There can be no assurance as to the adequacy for commercial success of Vascepa outside the United States. For example, even if we and Eddingpharmobtain marketing approval in countries within the China Territory, applicable regulatory agencies may impose restrictions on the product’s conditions foruse, distribution or marketing and in some cases may impose ongoing requirements for post-market surveillance, post-approval 44Table of Contentsstudies or clinical trials. Also, there is a degree of unpredictability with regard to the eventual pricing and reimbursement levels of medications in marketsoutside the United States. If the pricing and reimbursement levels of Vascepa are lower than we anticipate, then affordability of, and market access to,Vascepa may be adversely affected and thus market potential in these territories would suffer. Furthermore, with regard to any indications for which we maygain approval in territories outside the United States, the number of actual patients with the condition included in such approved indication may be smallerthan we anticipate. If any such approved indication is narrower than we anticipate, the market potential in these countries for our product would suffer.Our products and marketing efforts are subject to extensive post-approval government regulation.Once a product candidate receives FDA marketing approval, numerous post-approval requirements apply. Among other things, the holder of anapproved NDA is subject to periodic and other monitoring and reporting obligations enforced by the FDA and other regulatory bodies, including obligationsto monitor and report adverse events and instances of the failure of a product to meet the specifications in the approved application. Application holders mustalso submit advertising and other promotional material to regulatory authorities and report on ongoing clinical trials.With respect to sales and marketing activities including direct-to-healthcare provider and direct-to-consumer advertising and promotional activitiesinvolving the internet, advertising and promotional materials must comply with FDA rules in addition to other applicable federal and local laws in the UnitedStates and in other countries. The result of our First Amendment litigation and settlement may cause the government to scrutinize our promotional efforts orotherwise monitor our business more closely. Industry-sponsored scientific and educational activities also must comply with FDA and other requirements. Inthe United States, the distribution of product samples to physicians must comply with the requirements of the U.S. Prescription Drug Marketing Act.Manufacturing facilities remain subject to FDA inspection and must continue to adhere to the FDA’s pharmaceutical current good manufacturing practicerequirements, or cGMPs. Application holders must obtain FDA approval for product and manufacturing changes, depending on the nature of the change.We also are subject to the new federal transparency requirements under the Patient Protection and Affordable Care Act, as amended by the Health Careand Education Reconciliation Act, or collectively the PPACA, enacted in March 2010,which require manufacturers of certain drugs, devices, biologics, andmedical supplies to report to the Centers for Medicare & Medicaid Services, or CMS, information related to payments and other transfers of value tophysicians and teaching hospitals and physician ownership and investment interests. We may also be subject, directly or indirectly through our customersand partners, to various fraud and abuse laws, including, without limitation, the U.S. Anti-Kickback Statute, U.S. False Claims Act, and similar state laws,which impact, among other things, our proposed sales, marketing, and scientific/educational grant programs. If we participate in the U.S. Medicaid DrugRebate Program, the Federal Supply Schedule of the U.S. Department of Veterans Affairs, or other government drug programs, we will be subject to complexlaws and regulations regarding reporting and payment obligations. We must also comply with requirements to collect and report adverse events and productcomplaints associated with our products. For example, in September 2014, we participated in a routine inspection from the FDA in which the FDA madeobservations on perceived deficiencies related to our processes for collection and processing of adverse events. We have responded to FDA with respect tothese observations and continue to work with FDA to show that we have improved related systems and, given we received communication from the FDA thatit considers this matter to be closed, we believe that we have demonstrated to FDA that we have adequately responded to these observations. Our activitiesare also potentially subject to U.S. federal and state consumer protection and unfair competition laws. Similar requirements exist in many of these areas inother countries.Depending on the circumstances, failure to meet these post-approval requirements can result in criminal prosecution, fines or other penalties,injunctions, recall or seizure of products, total or partial suspension of production, denial or withdrawal of pre-marketing product approvals, or refusal toallow us to enter into supply contracts, including government contracts. We may also be held responsible for the non-compliance of our 45Table of Contentspartners, such as Kowa Pharmaceuticals America, Inc. In addition, even if we comply with FDA and other requirements, new information regarding the safetyor effectiveness of a product could lead the FDA to modify or withdraw a product approval. Adverse regulatory action, whether pre- or post-approval, canpotentially lead to product liability claims and increase our product liability exposure. We must also compete against other products in qualifying forcoverage and reimbursement under applicable third-party payment and insurance programs. In addition, all of the above factors may also apply to anyregulatory approval for Vascepa obtained within the China Territory under the DCS agreement with Eddingpharm and in other territories outside the UnitedStates. Given our inexperience with marketing and commercializing products outside the United States, we will need to rely on third parties, such asEddingpharm in China, to assist us in dealing with any such issues.Legislative or regulatory reform of the healthcare system in the United States and foreign jurisdictions may affect our ability to profitably sell Vascepa.Our ability to commercialize our future products successfully, alone or with collaborators, will depend in part on the extent to which coverage andreimbursement for the products will be available from government and health administration authorities, private health insurers and other third-party payors.The continuing efforts of the U.S. and foreign governments, insurance companies, managed care organizations and other payors of healthcare services tocontain or reduce healthcare costs may adversely affect our ability to set prices for our products which we believe are fair, and our ability to generate revenuesand achieve and maintain profitability.Specifically, in both the United States and some foreign jurisdictions, there have been a number of legislative and regulatory proposals to change thehealthcare system in ways that could affect our ability to sell our products profitably. For example, the Patient Protection and Affordable Care Act, asamended by the Health Care and Education Reconciliation Act, or collectively the PPACA, enacted in March 2010, substantially changes the way healthcareis financed by both governmental and private insurers. Among other cost-containment measures, PPACA establishes: • An annual, nondeductible fee on any entity that manufactures or imports certain branded prescription drugs and biologic agents; • A new Medicare Part D coverage gap discount program, in which pharmaceutical manufacturers who wish to have their drugs covered under PartD must offer discounts to eligible beneficiaries during their coverage gap period; and • A new formula that increases the rebates a manufacturer must pay under the Medicaid Drug Rebate Program.We expect further federal and state proposals and healthcare reforms to continue to be proposed by legislators, which could limit the prices that can becharged for the products we develop and may limit our commercial opportunity. It appears likely that the Affordable Care Act will continue the pressure onpharmaceutical pricing, especially under the Medicare and Medicaid programs, and may also increase our regulatory burdens and operating costs. Legislativechanges to the Affordable Care Act remain possible, and appear likely in the 115th United States Congress and under the Trump Administration.The continuing efforts of government and other third-party payors to further contain or reduce the costs of healthcare through various means may limitour commercial opportunity. It will be time consuming and expensive for us to go through the process of seeking coverage and reimbursement from Medicareand private payors. Our products may not be considered cost effective, and government and third-party private health insurance coverage and reimbursementmay not be available to patients for any of our future products or sufficient to allow us to sell our products on a competitive and profitable basis. Our resultsof operations could be adversely affected by PPACA and by other healthcare reforms that may be enacted or adopted in the future. In addition, increasingemphasis on managed care in the United States will continue to put pressure on the pricing of pharmaceutical products. Cost control initiatives coulddecrease the price that we or any potential collaborators could receive for any of our future products and could adversely affect our profitability. 46Table of ContentsIn some foreign countries, including major markets in the European Union and Japan, the pricing of prescription pharmaceuticals is subject togovernmental control. In these countries, pricing negotiations with governmental authorities can take 6 to 12 months or longer after the receipt of regulatorymarketing approval for a product. To obtain reimbursement or pricing approval in some countries, we may be required to conduct a pharmacoeconomic studythat compares the cost-effectiveness of Vascepa to other available therapies. Such pharmacoeconomic studies can be costly and the results uncertain. Ourbusiness could be harmed if reimbursement of our products is unavailable or limited in scope or amount or if pricing is set at unsatisfactory levels.The FDA and other regulatory agencies strictly regulate the promotional claims that may be made about prescription products. If we or our partnersare found to have improperly promoted uses of Vascepa, we may become subject to significant fines and other liability. The government may seek tofind means to prevent our promotion of truthful and non-misleading information beyond the current court ruling and litigation settlement.The FDA and other regulatory agencies strictly regulate the promotional claims that may be made about prescription products. In particular, in general,the U.S. government’s position has been that a product may not be promoted for uses that are not approved by the FDA as reflected in the product’s approvedlabeling. Even though we received FDA marketing approval for Vascepa for the MARINE indication and we believe the First Amendment court ruling andlitigation settlement affords us a degree of protection for other promotional efforts, physicians may still prescribe Vascepa to their patients for use in thetreatment of conditions that are not included as part of the indication statement in our FDA-approved Vascepa label or our settlement. If we are found to havepromoted Vascepa outside the terms of the litigation settlement or in violation of what federal or state government may determine to be acceptable, we maybecome subject to significant government fines and other related liability, such as under the FDCA, the False Claims Act, or other theories of liability.Government may also seek to hold us responsible for the non-compliance of our co-promotion partner, Kowa Pharmaceuticals America, Inc., or ourcommercialization partner outside the United States, Eddingpharm. For example, the Federal government has levied large civil and criminal fines againstcompanies for alleged improper promotion and has enjoined several companies from engaging in off-label promotion. The FDA has also requested thatcompanies enter into consent decrees or permanent injunctions under which specified promotional conduct is changed or curtailed.In addition, incentives exist under applicable laws that encourage competitors, employees and physicians to report violations of rules governingpromotional activities for pharmaceutical products. These incentives could lead to so-called “whistleblower lawsuits” as part of which such persons seek tocollect a portion of moneys allegedly overbilled to government agencies due to, for example, promotion of pharmaceutical products beyond labeled claims.These incentives could also lead to suits that we have mischaracterized a competitor’s product in the marketplace and we may, as a result, be sued for allegeddamages to our competitors. Such lawsuits, whether with or without merit, are typically time-consuming and costly to defend. Such suits may also result inrelated shareholder lawsuits, which are also costly to defend.Even though we have a final settlement in our litigation related to promotion beyond FDA-approved labeling, our promotion would still be subject toa high, perhaps abnormally high, degree of scrutiny to ensure that our promotion remains within the permitted scope. Likewise, federal or state governmentmay seek to find other means to prevent our promotion of truthful and non-misleading information. 47Table of ContentsThe prospective 80% interim efficacy and safety analysis of the REDUCE-IT cardiovascular outcomes trial may not be completed in the contemplatedtimeframe and may not demonstrate to the independent committee monitoring the study a sufficient benefit risk result to warrant the independentcommittee recommending stopping the study early for overwhelming efficacy. The independent monitoring committee may, at its discretion, alsorecommend that the study be stopped for safety or related concerns.In September 2016, we announced that the DMC completed its review of the first pre-specified interim efficacy analysis upon reaching approximately60% of the target aggregate number of cardiovascular events in accordance with the SPA agreement for our REDUCE-IT cardiovascular outcomes trial and,consistent with previously stated expectations, recommended that the trial continue as planned without modification. The second planned interim analysis ofefficacy results will be triggered by the onset of approximately 80% of the target aggregate number of primary cardiovascular events in the study. Based onhistorical event rates, we anticipate that the onset of approximately 80% of events will occur in the first half of 2017, with the second pre-specified interimefficacy and safety analysis by the DMC expected in or about the third quarter of 2017. The interim efficacy analysis will be accompanied by an interimsafety analysis by the DMC. It may actually take longer than anticipated for the DMC assessment of data for the interim analysis.Further, as is typical of interim analyses, the statistical threshold for defining overwhelming efficacy on the primary endpoint that would call forstopping the study early in connection with such analysis is considerably higher than the threshold for defining statistical significance after the expectedcompletion of the study near the end of 2017. We do not expect the study to be stopped due to overwhelming efficacy at the next interim look. We haverequested the DMC to not recommend stopping the study early based only upon the achievement of statistical significance for the primary endpoint, but toensure that supportive trends of benefit are also consistently observed in certain secondary endpoints and subpopulations before recommending that thestudy be stopped early for overwhelming efficacy. For example, even if the appropriate studied cardiovascular events in the trial occur at sufficiently lowrates in the active, Vascepa, group as compared to the placebo group such that the study would be a success at completion, the more rigorous statisticalanalysis applied by the DMC at the interim analysis may not warrant stoppage of the study for overwhelming efficacy in connection with the interimanalysis. The study may also be stopped pursuant to recommendation by the DMC at this interim analysis due to low likelihood of obtaining a favorableresult at completion. Despite no formal futility analysis or boundary being pre-specified in the protocol, it is within the purview of the DMC to weigh allavailable information and recommend study stoppage or continuation.Moreover, it is the DMC that will make the formal recommendation as to whether to stop the study early or to continue as planned. We are blinded tothe interim analysis results and are informed by the DMC of the recommendation to stop the study or to continue as planned. The DMC may consider factorsoutside the pre-specified statistical analysis plan when assessing whether to recommend continuing the study as planned. For example, even if study resultsare sufficiently positive at the interim analysis to demonstrate overwhelming efficacy, the DMC at its discretion may recommend continuation of the study asplanned with the goal of arriving at more robust results at the planned study completion if it believes that waiting for more robust results outweighs thepotential medical benefit of stopping and unblinding the study early.The DMC has multiple times per year assessed safety data generated in the ongoing study and has thus far recommended to continue the study asplanned. Thus, multiple safety reviews to date have not warranted study stoppage. Nevertheless, the study may be stopped at any time based onrecommendations of the DMC due to safety concerns identified by the DMC during its ongoing and regularly scheduled safety data assessments.We may not be successful in developing or marketing future products if we cannot meet the extensive regulatory requirements of the FDA and otherregulatory agencies for quality, safety and efficacy.The success of our research and development efforts is dependent in part upon our ability, and the ability of our partners or potential partners, to meetregulatory requirements in the jurisdictions where we or our partners or 48Table of Contentspotential partners ultimately intend to sell such products once approved. The development, manufacture and marketing of pharmaceutical products aresubject to extensive regulation by governmental authorities in the United States and elsewhere. In the United States, the FDA generally requires preclinicaltesting and clinical trials of each drug to establish its safety and efficacy and extensive pharmaceutical development to ensure its quality before itsintroduction into the market. Regulatory authorities in other jurisdictions impose similar requirements. The process of obtaining regulatory approvals islengthy and expensive and the issuance of such approvals is uncertain. The commencement and rate of completion of clinical trials and the timing ofobtaining marketing approval from regulatory authorities may be delayed by many factors, including: • the lack of efficacy during clinical trials; • the inability to manufacture sufficient quantities of qualified materials under cGMPs for use in clinical trials; • slower than expected rates of patient recruitment; • the inability to observe patients adequately after treatment; • changes in regulatory requirements for clinical trials or preclinical studies; • the emergence of unforeseen safety issues in clinical trials or preclinical studies; • delay, suspension, or termination of a trial by the institutional review board responsible for overseeing the study at a particular study site; • unanticipated changes to the requirements imposed by regulatory authorities on the extent, nature or timing of studies to be conducted onquality, safety and efficacy; • government or regulatory delays or “clinical holds” requiring suspension or termination of a trial; and • political instability affecting our clinical trial sites, such as the potential for political unrest affecting our REDUCE-IT clinical trial sites in theUkraine and Russia.Even if we obtain positive results from early stage preclinical studies or clinical trials, we may not achieve the same success in future trials. Clinicaltrials that we or potential partners conduct may not provide sufficient safety and efficacy data to obtain the requisite regulatory approvals for productcandidates. The failure of clinical trials to demonstrate safety and efficacy for our desired indications could harm the development of that product candidateas well as other product candidates, and our business and results of operations would suffer. For example, the efficacy results of our Vascepa Phase 3 clinicaltrials for the treatment of Huntington’s disease were negative. As a result, we stopped development of that product candidate, revised our clinical strategy andshifted our focus to develop Vascepa for use in the treatment of cardiovascular disease. Questions can also arise on the quality of study data or its reliability.For example, during the public advisory committee meeting held by FDA as part of its review of our ANCHOR sNDA, a discussion regarding observed,nominally statistically significant changes from baseline in an adverse direction, while on background statin therapy, in certain lipid parameters, includingtriglycerides, in the placebo group, raised questions about the possibility that the mineral oil placebo used in the ANCHOR trial (and in the REDUCE-ITtrial) might not be biologically inert and might be viewed as artificially exaggerating the clinical effect of Vascepa when measured against placebo in theANCHOR trial. Ultimately, no strong evidence for biological activity of mineral oil was identified by the FDA before its approval of Vascepa after review ofthe MARINE and ANCHOR trials and consideration of other data regarding mineral oil. It was ultimately concluded that the between-group differences likelyprovided the most appropriate descriptions of the treatment effect of Vascepa and that whatever factor(s) led to the within-group changes over time in theplacebo group were likely randomly distributed to all treatment groups. Thus, the FDA approved Vascepa for use in the MARINE indication in July 2012,FDA did not dispute the veracity of the ANCHOR trial data and, in connection with the March 2016 agreement we reached with the FDA allowing us topromote the results of the ANCHOR study, the FDA did not require that we include any qualification related to this earlier question regarding the mineral oilplacebo. The FDA, early on in the course of the REDUCE-IT trial, directed the DMC for REDUCE-IT to periodically review unblinded lipid data to monitorfor signals that the placebo might 49Table of Contentsnot be inert. After each such quarterly unblinded safety analysis and review meeting to date, the DMC has recommended to continue the REDUCE-IT studyas planned. Each of these DMC recommendations has been shared with FDA. Amarin and FDA remain blinded to such study data. Despite the currentlypositive disposition of this matter, it illustrates that concerns such as this may arise in the future that could affect our product development, regulatory reviewor the public perception of our products and our future prospects.Any approvals that are obtained may be limited in scope, may require additional post-approval studies or may require the addition of labelingstatements focusing on product safety that could affect the commercial potential for our product candidates. Any of these or similar circumstances couldadversely affect our ability to gain approval for new indications and affect revenues from the sale of our products. Even in circumstances where products areapproved by a regulatory body for sale, the regulatory or legal requirements may change over time, or new safety or efficacy information may be identifiedconcerning a product, which may lead to the withdrawal of a product from the market or similar use restrictions. The discovery of previously unknownproblems with a clinical trial or product, or in connection with the manufacturer of products, may result in regulatory issues that prevent past or proposedfuture approvals of a product and/or restrictions on that product or manufacturer, including withdrawal of an indication or the product from the market, whichwould have a negative impact on our potential revenue stream.As we continue to evolve from a company primarily involved in research and development to a company also focused on establishing an infrastructurefor commercializing Vascepa, we may encounter difficulties in managing our growth and expanding our operations successfully.The process of establishing a commercial infrastructure is difficult, expensive and time-consuming. We have a relatively small sales organizationconsisting of approximately 150 sales professionals, including sales representatives and their managers. As our operations expand with the anticipatedgrowth of our product sales, we expect that we will need to manage additional relationships with various collaborative partners, suppliers and other thirdparties. Future growth will impose significant added responsibilities on members of management, including the need to identify, recruit, maintain andintegrate additional employees. Our future financial performance and our ability to commercialize Vascepa and to compete effectively will depend, in part,on our ability to manage our future growth effectively. To that end, we must be able to manage our development efforts effectively, and hire, train, integrateand retain additional management, administrative and sales and marketing personnel. We may not be able to accomplish these tasks, and our failure toaccomplish any of them could prevent us from successfully growing our company.Risks Related to our Reliance on Third PartiesOur supply of product for the commercial market and clinical trials is dependent upon relationships with third-party manufacturers and key suppliers.We have no in-house manufacturing capacity and rely on contract manufacturers for our clinical and commercial product supply. We cannot ensurethat we will successfully manufacture any product we may develop, either independently or under manufacturing arrangements, if any, with our third-partymanufacturers. Moreover, if any manufacturer should cease doing business with us or experience delays, shortages of supply or excessive demands on theircapacity, we may not be able to obtain adequate quantities of product in a timely manner, or at all.Any manufacturing problem, natural disaster affecting manufacturing facilities, or the loss of a contract manufacturer could be disruptive to ouroperations and result in lost sales. Any reliance on suppliers may involve several risks, including a potential inability to obtain critical materials and reducedcontrol over production costs, delivery schedules, reliability and quality. Any unanticipated disruption to future contract manufacture caused by problems atsuppliers could delay shipment of products, increase our cost of goods sold and/or result in lost sales. If our suppliers were unable to supply us with adequatevolumes of active pharmaceutical ingredient (drug substance) or encapsulated bulk product (drug product), it would have a material adverse effect on ourability to continue to commercialize Vascepa. 50Table of ContentsWe initially purchased all of our supply of the bulk compound (ethyl-EPA), or Vascepa API, from a single supplier, Nisshin Pharma, Inc., or Nisshin,located in Japan. Nisshin was approved by the FDA as a Vascepa API supplier as part of our FDA NDA for the MARINE indication in July 2012. In April2013, we announced the approval by the FDA of an NDA supplement for Chemport, Inc. and BASF (formerly Equateq Limited) as additional Vascepa APIsuppliers. We terminated our agreement with BASF due to its inability to meet the agreement requirements, may enter into a new development and supplyagreement with BASF, and may purchase API from BASF as it remains an NDA-approved supplier. In 2014, we obtained sNDA approval for a fourth supplierof API, which includes the manufacturing facility of Finorga SAS (Novasep). We currently purchase and use commercial supply from Novasep, Chemport, andNisshin. Each of the API manufacturers obtains supply of the key raw material to manufacture API from other qualified third-parties.While we have contractual freedom to source the API for Vascepa and have entered into supply agreements with multiple suppliers who also rely onother third-party suppliers to manufacture the API for Vascepa, Novasep, Nisshin and Chemport currently supply all of our API for Vascepa. Our strategy inadding API suppliers beyond Nisshin has been to expand manufacturing capacity, maintain competitive advantages, and mitigate the risk of reliance on anysingle supplier.Expanding manufacturing capacity and qualifying such capacity is difficult and subject to numerous regulations and other operational challenges. Theresources of our suppliers vary and are limited; costs associated with projected expansion and qualification can be significant. For example, Chemport, whichwas approved as one of our API suppliers in April 2013, is a privately-held company and their commitment to Vascepa supply has required them to seekadditional resources. There can be no assurance that the expansion plans of any of our suppliers will be successful. Our aggregate capacity to produce API isdependent upon the qualification of our API suppliers. Each of our API suppliers has outlined plans for potential further capacity expansion. If no additionalAPI supplier is approved by the FDA as part of an sNDA, our API supply will be limited to the API we purchase from previously approved suppliers. If ourthird-party manufacturing capacity is not expanded and/or compliant with applicable regulatory requirements, we may not be able to supply sufficientquantities of Vascepa to meet anticipated demand. We cannot guarantee that we can contract with any future manufacturer on acceptable terms or that anysuch alternative supplier will not require capital investment from us in order for them to meet our requirements. Alternatively, our purchase of supply mayexceed actual demand for Vascepa.We currently have encapsulation agreements with three commercial API encapsulators for the encapsulation of Vascepa: Patheon, Inc. (formerly BannerPharmacaps), Catalent Pharma Solutions, and Capsugel Plöermel SAS. These companies have qualified and validated their manufacturing processes and arecapable of manufacturing Vascepa. There can be no guarantee that additional other suppliers with which we have contracted to encapsulate API will bequalified to manufacture the product to our specifications or that these and any future suppliers will have the manufacturing capacity to meeting anticipateddemand for Vascepa.We may purchase too much or not enough supply to satisfy actual demand, which could have a material adverse effect on our financial results andfinancial condition.Certain of our agreements with our suppliers include minimum purchase obligations and limited exclusivity provisions. These purchases are generallymade on the basis of rolling twelve-month forecasts which in part are binding on us and the balance of which are subject to adjustment by us subject tocertain limitations. Certain of our agreements also include contractual minimum purchase commitments regardless of the rolling twelve-month forecasts. Wemay not purchase sufficient quantities of Vascepa to meet actual demand or our purchase of supply may exceed actual demand. In either case, such eventcould have a material adverse effect on our financial results and financial condition. 51Table of ContentsThe manufacture, packaging and distribution of pharmaceutical products such as Vascepa are subject to FDA regulations and those of similar foreignregulatory bodies. If we or our third-party manufacturers fail to satisfy these requirements, our product development and commercialization efforts maybe materially harmed.The manufacture, packaging and distribution of pharmaceutical products, such as Vascepa, are regulated by the FDA and similar foreign regulatorybodies and must be conducted in accordance with the FDA’s pharmaceutical current good manufacturing practices, or cGMPs, and comparable requirementsof foreign regulatory bodies. There are a limited number of manufacturers that operate under these cGMPs and International Council for Harmonisation ofTechnical Requirements for Registration of Pharmaceuticals for Human Use, or ICH, regulations who are both capable of manufacturing Vascepa and willingto do so. Failure by us or our third-party manufacturers to comply with applicable regulations, requirements, or guidelines could result in sanctions beingimposed on us, including fines, injunctions, civil penalties, failure of regulatory authorities to grant marketing approval of our products, delays, suspensionor withdrawal of approvals, license revocation, seizures or voluntary recalls of product, operating restrictions and criminal prosecutions, any of which couldsignificantly and adversely affect our business. If we are not able to manufacture Vascepa to required specifications through our current and potential APIsuppliers, we may be delayed in successfully supplying the product to meet anticipated demand and our anticipated future revenues and financial results maybe materially adversely affected.Changes in the manufacturing process or procedure, including a change in the location where the product is manufactured or a change of a third-partymanufacturer, may require prior FDA review and pre-approval of the manufacturing process and procedures in accordance with the FDA’s cGMPs. Any newfacility may be subject to a pre-approval inspection by the FDA and would again require us to demonstrate product comparability to the FDA. There arecomparable foreign requirements under ICH guidelines. This review may be costly and time consuming and could delay or prevent the launch of a product.Furthermore, the FDA and foreign regulatory agencies require that we be able to consistently produce the API and the finished product in commercialquantities and of specified quality on a repeated basis, including demonstrated product stability, and document our ability to do so. This requirement isreferred to as process validation. This includes stability testing, measurement of impurities and testing of other product specifications by validated testmethods. If the FDA does not consider the result of the process validation or required testing to be satisfactory, the commercial supply of Vascepa may bedelayed, or we may not be able to supply sufficient quantities of Vascepa to meet anticipated demand.The FDA and similar foreign regulatory bodies may also implement new requirements, or change their interpretation and enforcement of existingrequirements, for manufacture, packaging or testing of products at any time. If we or our approved suppliers are unable to comply, we may be subject toregulatory, civil actions or penalties which could significantly and adversely affect our business.We rely on third parties to conduct our clinical trials, and those third parties may not perform satisfactorily, including failing to meet establisheddeadlines for the completion of such clinical trials.Our reliance on third parties for clinical development activities reduces our control over these activities. However, if we sponsor clinical trials, we areresponsible for ensuring that each of our clinical trials is conducted in accordance with the general investigational plan and protocols for the trials. Moreover,the FDA requires us to comply with requirements, commonly referred to as good clinical practices, for conducting, recording, and reporting the results ofclinical trials to assure that data and reported results are credible and accurate and that the rights, integrity and confidentiality of trial participants areprotected. Our reliance on third parties does not relieve us of these responsibilities and requirements. Furthermore, these third parties may also haverelationships with other entities, some of which may be our competitors. If these third parties do not successfully carry out their contractual duties or meetexpected deadlines, we may be delayed in obtaining regulatory approvals for our product candidates and may be delayed in our efforts to successfullycommercialize our product candidates for targeted diseases. 52Table of ContentsWe are dependent upon our collaboration with Eddingpharm and others to commercialize Vascepa in certain regions outside of the United States, andif such third parties fail to successfully fulfill their obligations, or are ineffective in their commercialization of Vascepa, or if our collaborations areterminated, our plans to commercialize Vascepa outside of the United States may be adversely affected.In February 2015, we entered into the DCS Agreement with Eddingpharm, under which we granted exclusive rights to Eddingpharm to develop andcommercialize Vascepa in the China Territory. We are dependent on Eddingpharm for certain regulatory filings outside of the United States with respect toVascepa, which may require conducting clinical trials in the China Territory to secure regulatory approval, as well as the commercialization of Vascepaoutside of the United States. If Eddingpharm fails to perform its obligations under the DCS Agreement or is ineffective in its commercialization of Vascepa inthe China Territory or if we fail to effectively manage our relationship with Eddingpharm, our ability to and the extent to which we commercialize and obtaincertain regulatory approvals of Vascepa outside of the United States would be significantly harmed.In addition, Eddingpharm has the right to terminate the agreement under certain conditions. If Eddingpharm terminates the DCS Agreement, we wouldbe required to either enter into alternative arrangements with third parties to commercialize Vascepa in the China Territory, which we may be unable to do, orto increase our internal infrastructure, both of which would likely result in significant additional expense and delay or termination of our Vascepa clinicaldevelopment programs outside of the United States.We also have an agreement with Biologix, entered into in March 2016, to register and commercialize Vascepa in countries within the Middle East andNorth Africa. Commercialization across the region, as in China, is subject to similar third party risk.Risks Related to our Intellectual PropertyWe are dependent on patents, proprietary rights and confidentiality to protect the commercial potential of Vascepa.Our success depends in part on our ability to obtain and maintain intellectual property protection for our drug candidates, technology and know-how,and to operate without infringing the proprietary rights of others. Our ability to successfully implement our business plan and to protect our products with ourintellectual property will depend in large part on our ability to: • obtain, defend and maintain patent protection and market exclusivity for our current and future products; • preserve any trade secrets relating to our current and future products; • acquire patented or patentable products and technologies; and • operate without infringing the proprietary rights of third parties.We have prosecuted, and are currently prosecuting, multiple patent applications to protect the intellectual property developed during the Vascepadevelopment program. As of the date of this report, we had 51 patent applications in the United States that have been either issued or allowed and more than30 additional patent applications are pending in the United States. Such 51 allowed and issued applications include the following: • 2 issued U.S. patents directed to a pharmaceutical composition of Vascepa in a capsule that have terms that expire in 2020 and 2030,respectively, • 1 issued U.S. patent covering a composition containing highly pure EPA that expires in 2021, • 39 U.S. patents covering or related to the use of Vascepa in either the MARINE or ANCHOR populations that have terms that expire in 2030 orlater, • 3 additional patents related to the use of a pharmaceutical composition comprised of free fatty acids to treat the ANCHOR patient populationwith a term that expires in 2030, 53Table of Contents • 2 additional patents related to the use of a pharmaceutical composition comprised of free fatty acids to treat the MARINE patient populationwith a term that expires in 2030, • 1 additional patent related to a pharmaceutical composition comprised of free fatty acids and uses thereof to treat both the MARINE andANCHOR patient populations with a term that expires in 2030, • 1 additional patent related to a formulation of EPA/DHA and uses thereof with a term that expires in 2030, • 1 additional patent related to the use of Vascepa to treat obesity with a term that expires in 2030, and • 1 additional patent covering a pharmaceutical composition comprised of EPA and a hydroxyl compound with a term that expires in 2034.A Notice of Allowance is issued after the USPTO makes a determination that a patent can be granted from an application. A Notice of Allowance doesnot afford patent protection until the underlying patent is issued by the USPTO. No assurance can be given that applications with issued notices of allowancewill be issued as patents or that any of our pending patent applications will issue as patents. No assurance can be given that, if and when issued, our patentswill prevent competitors from competing with Vascepa. For example, we may choose to not assert all issued patents in patent litigation and patents or claimswithin patents may be determined to be invalid.We are also pursuing patent applications related to Vascepa in multiple jurisdictions outside the United States. We may be dependent in some casesupon third-party licensors to pursue filing, prosecution and maintenance of patent rights or applications owned or controlled by those parties. It is possiblethat third parties will obtain patents or other proprietary rights that might be necessary or useful to us. In cases where third parties are first to invent aparticular product or technology, or first to file after various provisions of the America Invents Act of 2011 went into effect on March 16, 2013, it is possiblethat those parties will obtain patents that will be sufficiently broad so as to prevent us from utilizing such technology or commercializing our current andfuture products.Although we intend to make reasonable efforts to protect our current and future intellectual property rights and to ensure that any proprietarytechnology we acquire or develop does not infringe the rights of other parties, we may not be able to ascertain the existence of all potentially conflictingclaims. Therefore, there is a risk that third parties may make claims of infringement against our current or future products or technologies. In addition, thirdparties may be able to obtain patents that prevent the sale of our current or future products or require us to obtain a license and pay significant fees orroyalties in order to continue selling such products.We may in the future discover the existence of products that infringe patents that we own or that have been licensed to us. If we were to initiate legalproceedings against a third party to stop such an infringement, such proceedings could be costly and time consuming, regardless of the outcome. Noassurances can be given that we would prevail, and it is possible that, during such a proceeding, our patent rights could be held to be invalid, unenforceableor both. Although we intend to protect our trade secrets and proprietary know-how through confidentiality agreements with our manufacturers, employeesand consultants, we may not be able to prevent parties subject to such confidentiality agreements from breaching these agreements or third parties fromindependently developing or learning of our trade secrets.We anticipate that competitors may from time to time oppose our efforts to obtain patent protection for new technologies or to submit patentedtechnologies for regulatory approvals. Competitors may seek to oppose our patent applications to delay the approval process or to challenge our grantedpatents, for example, by requesting a reexamination of our patent at the USPTO, or by filing an opposition in a foreign patent office, even if the opposition orchallenge has little or no merit. For example, one of our patents was revoked in an opposition proceeding in Europe due to a determination of improper claimamendments under a provision of law not applicable in the United States. Such proceedings are generally highly technical, expensive, and time consuming, 54Table of Contentsand there can be no assurance that such a challenge would not result in the narrowing or complete revocation of any patent of ours that was so challenged.Our issued patents may not prevent competitors from competing with Vascepa, even if we seek to enforce our patent rights.We plan to vigorously defend our rights under issued patents. For example, in March 2014, we filed a patent infringement suit against OmtheraPharmaceuticals, Inc., and its parent company, AstraZeneca Pharmaceuticals LP. The suit sought injunctive relief and monetary damages for infringement ofour U.S. Patent No. 8,663,662. The complaint alleged infringement of the patent arising from the expected launch of Epanova, a product that is expected tocompete with Vascepa in the United States. The patent covers methods of lowering triglycerides by administering a pharmaceutical composition thatincludes amounts of EPA as free acid, and no more than about 30% DHA. In November 2014, based on a representation from AstraZeneca Pharmaceuticals LPthat the commercial launch of Epanova was not imminent, the court dismissed our complaint, without prejudice (i.e., preserving our ability to later re-file thesuit). The court required the defendant to notify us before any product launch. We intend to pursue this litigation vigorously and aggressively protect itsintellectual property rights. However, patent litigation is a time-consuming and costly process. There can be no assurance that we will be successful inenforcing this patent or that it will not be successfully challenged and invalidated. Even if we are successful in enforcing this patent, the process could takeyears to reach conclusion.Other drug companies may challenge the validity, enforceability, or both of our patents and seek to design its products around our issued patent claimsand gain marketing approval for generic versions of Vascepa or branded competitive products based on new clinical studies. The pharmaceutical industry ishighly competitive and many of our competitors have greater experience and resources than we have. Any such competition could undermine sales,marketing and collaboration efforts for Vascepa, and thus reduce, perhaps materially, the revenue potential for Vascepa.Even if we are successful in enforcing our issued patents, we may incur substantial costs and divert management’s time and attention in pursuing theseproceedings, which could have a material adverse effect on us. Patent litigation is costly and time consuming, and we may not have sufficient resources tobring these actions to a successful conclusion.There can be no assurance that any of our pending patent applications relating to Vascepa or its use will issue as patents.We have filed and are prosecuting numerous families of patent applications in the United States and internationally with claims designed to protect theproprietary position of Vascepa. For certain of these patent families, we have filed multiple patent applications. Collectively the patent applications includenumerous independent claims and dependent claims. Several of our patent applications contain claims that are based upon what we believe are unexpectedand favorable findings from the MARINE and ANCHOR trials. If granted, many of the resulting granted patents would expire in 2030 or beyond. However, noassurance can be given that these additional MARINE and ANCHOR patents or any of our pending patent applications intended to cover an indication basedon future results from the REDUCE-IT clinical trial will be granted or, if they grant, that they will prevent competitors from competing with Vascepa.Securing patent protection for a product is a complex process involving many legal and factual questions. The patent applications we have filed in theUnited States and internationally are at varying stages of examination, the timing of which is outside our control. The process to getting a patent granted canbe lengthy and claims initially submitted are often modified in order to satisfy the requirements of the patent office. This process includes written and publiccommunication with the patent office. The process can also include direct discussions with the patent examiner. There can be no assurance that the patentoffice will accept our arguments with respect to any patent application or with respect to any claim therein. The timing of the patent review 55Table of Contentsprocess is independent of and has no effect on the timing of the FDA’s review of our NDA or sNDA submissions. We cannot predict the timing or results ofany patent application. In addition, we may elect to submit, or the patent office may require, additional evidence to support certain of the claims we arepursuing. Furthermore, third parties may attempt to submit publications for consideration by the patent office during examination of our patent applications.Providing such additional evidence and publications could prolong the patent office’s review of our applications and result in us incurring additional costs.We cannot be certain what commercial value any granted patent in our patent estate will provide to us.Despite the use of confidentiality agreements and/or proprietary rights agreements, which themselves may be of limited effectiveness, it may be difficultfor us to protect our trade secrets.In addition to our patent portfolio and strategy, we will also rely upon trade secrets and know-how to help protect our competitive position. We rely ontrade secrets to protect technology in cases when we believe patent protection is not appropriate or obtainable. However, trade secrets are difficult to protect.While we require certain of our academic collaborators, contractors and consultants to enter into confidentiality agreements, we may not be able toadequately protect our trade secrets or other proprietary information.Risks Related to our BusinessIf the estimates we make, or the assumptions on which we rely, in preparing our projected guidance prove inaccurate, our actual results may vary fromthose reflected in our projections and accruals.In January 2017, we issued financial and business guidance, including expected fiscal year 2017 total net revenue and expectations regardingimproved cash flow from commercial operations and timing of the REDUCE-IT outcomes trial. All such guidance is based on estimates and the judgment ofmanagement. Because of the inherent nature of estimates, there could be significant differences between our estimates and the actual amount of productdemand. If, for any reason, we are unable to realize our currently projected 2017 revenue, we may not realize our publicly announced financial guidance. Ifwe fail to realize or if we change or update any element of our publicly disclosed financial guidance or other expectations about our business, our stock pricecould decline in value.We and certain of our current and former executive officers were named as defendants in a class action lawsuit that could result in substantial costs anddivert management’s attention.The market price of our American Depositary Shares, or ADSs, declined significantly after the October 2013 decision by the FDA Advisory Committeeto recommend against approval of Vascepa in the ANCHOR indication. We and certain of our current and former executive officers and directors were namedas defendants in a class action lawsuit that generally alleged that we and certain of our current and former officers and directors violated Sections 10(b) and/or20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder by making allegedly false and/or misleading statements or materialomissions concerning the ANCHOR sNDA and related FDA regulatory approval process in an effort to lead investors to believe that Vascepa would receiveapproval from the FDA in the ANCHOR indication. The complaints sought unspecified damages, interest, attorneys’ fees, and other costs.We engaged in a vigorous defense of this lawsuit. On June 29, 2015, the court granted our first motion to dismiss the class action litigation withoutprejudice. The court held that the plaintiffs failed to state a claim upon which relief could be granted and plaintiffs were given 30 days to refile an amendedcomplaint.On July 29, 2015, the plaintiffs filed an amended complaint and we again moved to dismiss. On April 26, 2016, the court granted a second motion todismiss, again without prejudice, with leave for plaintiffs to file an amended complaint. On May 24, 2016, plaintiffs notified the court they would not fileanother amended complaint and on September 21, 2016, filed a brief in support of their appeal of the most recent dismissal to the Third Circuit Court ofAppeals. We plan to continue with our vigorous defense in connection with this appeal. 56Table of ContentsWe are unable to predict the ultimate outcome of this matter at this time. While we expect insurance to cover any financial exposure from thislitigation, the conclusion of this matter in a manner adverse to us could have a material adverse effect on our financial condition and business. For example,we could incur substantial costs not covered by our directors’ and officers’ liability insurance, suffer a significant adverse impact on our reputation and divertmanagement’s attention and resources from other priorities, including the execution of business plans and strategies that are important to our ability to growour business, any of which could have a material adverse effect on our business. In addition, any of these matters could require payments that are not coveredby, or exceed the limits of, our available directors’ and officers’ liability insurance, which could have a material adverse effect on our operating results orfinancial condition.Potential technological changes in our field of business create considerable uncertainty.We are engaged in the biopharmaceutical field, which is characterized by extensive research efforts and rapid technological progress. Newdevelopments in research are expected to continue at a rapid pace in both industry and academia. We cannot assure you that research and discoveries byothers will not render some or all of our programs or product candidates uncompetitive or obsolete. Our business strategy is based in part upon new andunproven technologies to the development of therapeutics to improve cardiovascular health. We cannot assure you that unforeseen problems will notdevelop with these technologies or applications or that any commercially feasible products will ultimately be developed by us.We are subject to potential product liability.Following the commercial launch of Vascepa, we will be subject to the potential risk of product liability claims relating to the manufacturing andmarketing of Vascepa. Any person who is injured as a result of using Vascepa may have a product liability claim against us without having to prove that wewere at fault.In addition, we could be subject to product liability claims by persons who took part in clinical trials involving our current or former developmentstage products. A successful claim brought against us could have a material adverse effect on our business. We cannot guarantee that a product liability claimwill not be asserted against us in the future.We may become subject to liability in connection with the wind-down of our EN101 program.In 2007, we purchased Ester Neurosciences Limited, an Israeli pharmaceutical company, and its lead product candidate, EN101, an AChE-R mRNAinhibitor for the treatment of myasthenia gravis, or MG, a debilitating neuromuscular disease. In connection with the acquisition, we assumed a license tocertain intellectual property assets related to EN101 from the Yissum Research Development Company of The Hebrew University of Jerusalem. In keepingwith our 2009 decision to re-focus our efforts on developing improved treatments for cardiovascular disease and cease development of all product candidatesoutside of our cardiovascular disease focus, we amended the terms of our acquisition agreement with the original shareholders of Ester.Following our decision to cease development of EN101, Yissum terminated its license agreement with us. In June 2011, Yissum announced that it hadentered into a license agreement with BiolineRX Ltd for the development of EN101 in a different indication, inflammatory bowel disease.In 2011 and early 2012, but not after, we received several communications on behalf of the former shareholders of Ester asserting that we are in breachof our agreement with them as it relates to alleged rights to share in the value of EN101 due to the fact that Yissum terminated its license. We do not believethe circumstances presented constitute a breach of the agreement. If the dispute arises again, we plan to defend our position vigorously, but there can be noassurance as to the outcome of this dispute. 57Table of ContentsA change in our tax residence could have a negative effect on our future profitability.Under current UK legislation, a company incorporated in England and Wales, or which is centrally managed and controlled in the UK, is regarded asresident in the UK for taxation purposes. Under current Irish legislation, a company is regarded as resident for tax purposes in Ireland if it is centrallymanaged and controlled in Ireland, or, in certain circumstances, if it is incorporated in Ireland. Where a company is treated as tax resident under the domesticlaws of both the UK and Ireland then the provisions of article 4(3) of the Double Tax Convention between the UK and Ireland provides that such enterpriseshall be treated as resident only in the jurisdiction in which its place of effective management is situated. We have sought to conduct our affairs in such a wayso as to be resident only in Ireland for tax purposes by virtue of having our place of effective management situated in Ireland. Trading income of an Irishcompany is generally taxable at the Irish corporation tax rate of 12.5%. Non-trading income of an Irish company (e.g., interest income, rental income or otherpassive income) is taxable at a rate of 25%.However, we cannot assure you that we are or will continue to be resident only in Ireland for tax purposes. It is possible that in the future, whether as aresult of a change in law or the practice of any relevant tax authority or as a result of any change in the conduct of our affairs, we could become, or beregarded as having become resident in a jurisdiction other than Ireland. Our and our subsidiaries’ income tax returns are periodically examined by various taxauthorities. We are currently under audit by the United States Internal Revenue Service (IRS) for the years 2012 to 2013. Although the outcome of tax auditsis always uncertain and could result in significant cash tax payments, we do not believe the outcome of these audits will have a material adverse effect on ourconsolidated financial position or results of operations. The ultimate resolution may result in a payment that is materially different from our current estimateof the tax liabilities. Should we cease to be an Irish tax resident, we may be subject to a charge to Irish capital gains tax on our assets. Similarly, if the taxresidency of any of our subsidiaries were to change from their current jurisdiction for any of the reasons listed above, we may be subject to a charge to localcapital gains tax charge on the assets.The loss of key personnel could have an adverse effect on our business.We are highly dependent upon the efforts of our senior management. The loss of the services of one or more members of senior management could havea material adverse effect on us. As a small company with a streamlined management structure, the departure of any key person could have a significant impactand would be potentially disruptive to our business until such time as a suitable replacement is hired. Furthermore, because of the specialized nature of ourbusiness, as our business plan progresses we will be highly dependent upon our ability to attract and retain qualified scientific, technical and keymanagement personnel. As we evolve from a development stage company to a commercial stage company we may experience turnover among members ofour senior management team. We may have difficulty identifying and integrating new executives to replace any such losses. There is intense competition forqualified personnel in the areas of our activities. In this environment, we may not be able to attract and retain the personnel necessary for the development ofour business, particularly if we do not achieve profitability. The failure to recruit key scientific, technical and management personnel would be detrimental toour ability to implement our business plan.We could be adversely affected by our exposure to customer concentration risk.A significant portion of our sales are to wholesalers in the pharmaceutical industry. Our top three customers accounted for 95% of gross product salesfor each of the years ended December 31, 2016 and 2015 and represented 96% and 95% of the gross accounts receivable balance as of December 31, 2016and 2015, respectively. There can be no guarantee that we will be able to sustain our accounts receivable or gross sales levels from our key customers. If, forany reason, we were to lose, or experience a decrease in the amount of business with our largest customers, whether directly or through our distributorrelationships, our financial condition and results of operations could be negatively affected. 58Table of ContentsRisks Related to our Financial Position and Capital RequirementsWe have a history of operating losses and anticipate that we will incur continued losses for an indefinite period of time.We have not yet reached profitability. For the fiscal years ended December 31, 2016, 2015, and 2014, we reported losses of approximately$86.4 million, $149.1 million, and $56.4 million, respectively, and we had an accumulated deficit as of December 31, 2016 of $1.2 billion. Substantially allof our operating losses resulted from costs incurred in connection with our research and development programs, from general and administrative costsassociated with our operations, and costs related to the commercialization of Vascepa. Additionally, as a result of our significant expenses relating to researchand development and to commercialization, we expect to continue to incur significant operating losses for an indefinite period. Because of the numerousrisks and uncertainties associated with developing and commercializing pharmaceutical products, we are unable to predict the magnitude of these futurelosses. Our historic losses, combined with expected future losses, have had and will continue to have an adverse effect on our cash resources, shareholders’deficit and working capital.Although we began generating revenue from Vascepa in January 2013, we may never be profitable.Our ability to become profitable depends upon our ability to generate revenue. We have been generating product revenue from sales of Vascepa sinceJanuary 2013, but we may not be able to generate sufficient revenue to attain profitability. Our ability to generate profits on sales of Vascepa is subject to themarket acceptance and commercial success of Vascepa and our ability to manufacture commercial quantities of Vascepa through third parties at acceptablecost levels, and may also depend upon our ability to effectively market and sell Vascepa through our strategic collaborations.Even though Vascepa has been approved by the FDA for marketing in the United States in the MARINE indication, it may not gain market acceptanceor achieve commercial success and it may never be approved for the ANCHOR indication or any other indication. In addition, we anticipate continuing toincur significant costs associated with commercializing Vascepa. We may not achieve profitability in the near term due to high costs associated with ourREDUCE-IT study and commercialization efforts, for example. If we are unable to continue to generate robust product revenues, we will not becomeprofitable in the near term, if ever, and may be unable to continue operations without continued funding.Our historical financial results do not form an accurate basis for assessing our current business.As a consequence of the many years developing Vascepa for commercialization and the commercial launch of Vascepa in 2013 in the United States,our historical financial results do not form an accurate basis upon which investors should base their assessment of our business and prospects. In addition, weexpect that our costs will increase substantially as we continue to commercialize Vascepa in the MARINE indication and with ANCHOR data and seek toobtain additional regulatory approval of Vascepa from continuation of the REDUCE-IT cardiovascular outcomes study. Accordingly, our historical financialresults reflect a substantially different business from that currently being conducted and from that expected in the future. In addition, we have a limitedhistory of obtaining regulatory approval for, and no demonstrated ability to successfully commercialize, a product candidate. Consequently, any predictionsabout our future performance may not be as accurate as they could be if we had a history of successfully developing and commercializing pharmaceuticalproducts.Our operating results are unpredictable and may fluctuate. If our operating results are below the expectations of securities analysts or investors, thetrading price of our stock could decline.Our operating results are difficult to predict and will likely fluctuate from quarter to quarter and year to year, and Vascepa prescription figures willlikely fluctuate from month to month. Vascepa sales are difficult to predict from period to period and as a result, you should not rely on Vascepa sales resultsin any period as being indicative of future performance, and sales of Vascepa may be below the expectation of securities analysts or 59Table of Contentsinvestors in the future. We believe that our quarterly and annual results of operations may be affected by a variety of factors, including: • the level of demand for Vascepa, due to changes in prescriber sentiment, quarterly changes in Distributor purchases, and other factors; • the extent to which coverage and reimbursement for Vascepa is available from government and health administration authorities, private healthinsurers, managed care programs and other third-party payers; • the timing, cost and level of investment in our sales and marketing efforts to support Vascepa sales and the resulting effectiveness of those effortswith our new co-promotion partner, Kowa Pharmaceuticals America, Inc.; • the timing and ability of commercialization partners outside the United States, such as Eddingpharm and Biologix, to develop, register andcommercialize Vascepa in the China Territory, several Middle Eastern and North African countries, and other territories outside the UnitedStates, including obtaining necessary regulatory approvals and establishing marketing channels; • additional developments regarding our intellectual property portfolio and regulatory exclusivity protections, if any; • the timing and nature of results of the REDUCE-IT study or post-approval studies for Vascepa; • outcomes of litigation and other legal proceedings, including our pending FDA determination on regulatory exclusivity, shareholder litigation,regulatory matters and tax matters; and • our regulatory dialogue on the REDUCE-IT study.We may require substantial additional resources to fund our operations. If we cannot find additional capital resources, we will have difficulty inoperating as a going concern and growing our business.We currently operate with limited resources. We believe that our cash and cash equivalents balance of $98.3 million as of December 31, 2016 will besufficient to fund our projected operations through the results of the REDUCE-IT study, which we anticipate will be available mid-2018. Depending on thelevel of cash generated from operations, additional capital may be required to sustain operations, fund debt obligations or expand promotion of Vascepa ascontemplated following anticipated successful results of the REDUCE-IT study. We anticipate that quarterly net cash outflows in future periods will bevariable.In order to fully realize the market potential of Vascepa, we may need to enter into a new strategic collaboration or raise additional capital. We mayalso need additional capital to fully complete our REDUCE-IT cardiovascular outcomes trial.Our future capital requirements will depend on many factors, including: • the timing, amount and consistency of revenue generated from the commercial sale of Vascepa; • the costs associated with commercializing Vascepa in the United States and for additional indications in the United States and in jurisdictions inwhich we receive regulatory approval, if any, including the cost of sales and marketing capabilities with our new co-promotion partner, KowaPharmaceuticals America, Inc., and the cost and timing of securing commercial supply of Vascepa and the timing of entering into any newstrategic collaboration with others relating to the commercialization of Vascepa, if at all, and the terms of any such collaboration; • the continued cost associated with our REDUCE-IT cardiovascular outcomes study; • continued costs associated with litigation and other legal proceedings; • the time and costs involved in obtaining additional regulatory approvals for Vascepa; 60Table of Contents • the extent to which we continue to develop internally, acquire or in-license new products, technologies or businesses; and • the cost of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights.If we require additional funds and adequate funds are not available to us in amounts or on terms acceptable to us or on a timely basis, or at all, ourcommercialization efforts for Vascepa may suffer materially, and we may need to delay the advancement of the REDUCE-IT cardiovascular outcomes trial.We have substantial net operating loss carryforwards for tax purposes, the majority of which are from operations in Ireland. The potential futurebenefit of such net operating loss carryforwards could be lost if tax regulations change or if we are deemed to not have active operations in Ireland.Amarin developed Vascepa, known during development as AMR101, in and from Ireland. In recent years, particularly since 2013 when commercialsale of Vascepa commenced in the United States, the majority of Amarin’s consolidated operations have been in the United States. Ownership to Vascepacontinues to reside with Amarin’s wholly-owned Ireland-based subsidiary, Amarin Pharmaceuticals Ireland Ltd., and oversight and operations of that entityare structured to be maintained in Ireland. In order to effectively utilize Amarin’s accumulated net operating loss carryforwards for tax purposes in Ireland,Amarin operations, particularly for this subsidiary, need to be active in Ireland. In addition, utilization of these accumulated net operating loss carryforwardsassume that tax treaties between Ireland and other countries, particularly the United States, do not change in a manner which limit Amarin’s future ability tooffset earnings with these operating loss carryforwards for tax purposes.Continued negative economic conditions would likely have a negative effect on our ability to obtain financing on acceptable terms.While we may seek additional funding through public or private financings, we may not be able to obtain financing on acceptable terms, or at all.There can be no assurance that we will be able to access equity or credit markets in order to finance our current operations or expand development programsfor Vascepa, or that there will not be a further deterioration in financial markets and confidence in economies. We may also have to scale back or furtherrestructure our operations. If we are unable to obtain additional funding on a timely basis, we may be required to curtail or terminate some or all of ourresearch or development programs or our commercialization strategies.Raising additional capital may cause dilution to our existing shareholders, restrict our operations or require us to relinquish rights.To the extent we are permitted under our Purchase and Sale Agreement with BioPharma Secured Debt Fund II Holdings Cayman LP, or BioPharma, wemay seek additional capital through a combination of private and public equity offerings, debt financings and collaboration, strategic and licensingarrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, your ownership interest will be diluted,and the terms may include liquidation or other preferences that adversely affect your rights as a shareholder.In January 2012, Corsicanto Designated Activity Company (formerly Corsicanto Limited), or Corsicanto, issued $150.0 million in aggregate principalamount of 3.5% exchangeable senior notes due 2032, or the 2012 Notes. In May 2014, we entered into separate, privately negotiated exchange agreementswith certain holders of the 2012 Notes pursuant to which Corsicanto exchanged $118.7 million in aggregate principal amount of the existing 2012 Notes for$118.7 million in aggregate principal amount of new 3.5% May 2014 Exchangeable Senior Notes due 2032, or the 2014 Notes. In November 2015, we issued$31.3 million in aggregate principal 61Table of Contentsamount of 3.5% exchangeable senior notes due 2032, or the 2015 Notes, and used $16.2 million of the proceeds to repay a portion of the 2012 Notes, suchthat $15.1 million of 2012 Notes remained outstanding. In September 2016, we mandatorily exchanged the entirety of the 2014 Notes and 2015 Notes, inaccordance with their respective terms, into 60,311,188 ADSs. In January 2017, approximately $15.0 million of the 2012 Notes were put to us, such that$0.1 million of the 2012 Notes currently remains outstanding. We have initiated the process to redeem the $0.1 million of outstanding principal amount of2012 Notes, which we expect will be completed in the first quarter of 2017. In the event of physical settlement, the remaining $0.1 million of 2012 Noteswould be exchangeable into a total of 15,092 ADSs.In January 2017, Corsicanto II Designated Activity Company, or Corsicanto II, issued $30.0 million in aggregate principal amount of 3.5%exchangeable senior notes due 2047, or the 2017 Notes. In the event of physical settlement, the 2017 Notes would be exchangeable into a total of 7,716,048ADSs.Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions such as incurringadditional debt, making capital expenditures or declaring dividends. If we raise additional funds through collaboration, strategic alliance and licensingarrangements with third parties, we may have to relinquish valuable rights to our technologies, Vascepa or product candidates beyond the rights we havealready relinquished, or grant licenses on terms that are not favorable to us.Potential business combinations or other strategic transactions may disrupt our business or divert management’s attention.On a regular basis, we explore potential business combination transactions, including an acquisition of us by a third party, exclusive licenses ofVascepa or other strategic transactions or collaborations with third parties. For example, in March 2014, we entered into a co-promotion agreement withKowa Pharmaceuticals America, Inc. related to the commercialization of Vascepa in the United States. The consummation and performance of any such futuretransactions or collaborations will involve risks, such as: • diversion of managerial resources from day-to-day operations; • exposure to litigation from the counterparties to any such transaction, other third parties or our shareholders; • misjudgment with respect to the value; • higher than expected transaction costs; or • an inability to successfully consummate any such transaction or collaboration.As a result of these risks, we may not be able to achieve the expected benefits of any such transaction or collaboration or deliver the value thereof toour shareholders. If we are unsuccessful in consummating any such transaction or collaboration, we may be required to reevaluate our business only after wehave incurred substantial expenses and devoted significant management time and resources.Risks Related to Ownership of our ADSs and Common SharesThe price of our ADSs and common shares may be volatile.The stock market has from time to time experienced significant price and volume fluctuations that may be unrelated to the operating performance ofparticular companies. In addition, the market prices of the securities of many pharmaceutical and medical technology companies have been especiallyvolatile in the past, and this trend is expected to continue in the future.As of February 20, 2017 we had 272,061,557 common shares outstanding including 269,369,455 shares held as ADSs and 2,692,102 held as commonshares (which are not held in the form of ADSs). There is a risk 62Table of Contentsthat there may not be sufficient liquidity in the market to accommodate significant increases in selling activity or the sale of a large block of our securities.Our ADSs have historically had limited trading volume, which may also result in volatility. If any of our large investors, such as the participants in our March2015 private placement, seek to sell substantial amounts of our ADSs, particularly if these sales are in a rapid or disorderly manner, or other investors perceivethat these sales could occur, the market price of our ADSs could decrease significantly.The market price of our ADSs and common shares may also be affected by factors such as: • developments or disputes concerning ongoing patent prosecution efforts and any future patent or proprietary rights; • litigation and regulatory developments in the United States affecting our Vascepa promotional rights, and regulatory developments in theEuropean Union or other countries; • actual or potential medical results relating to our products or our competitors’ products; • interim failures or setbacks in product development; • innovation by us or our competitors; • currency exchange rate fluctuations; and • period-to-period variations in our results of operations.The number of our ordinary shares, or ADSs representing such ordinary shares, outstanding may increase substantially as a result of our March 2015private placement and the later consolidation and redesignation of the Series A Preference Shares represented by Preference ADSs issued thereunder,and some of the investors may then beneficially own significant blocks of our ordinary shares; the ordinary shares and Series A Preference Sharesresulting from the private placement will be generally available for resale in the public market upon registration under the Securities Act.In March and July 2015, we completed a private placement of American Depositary Shares in two tranches representing 352,150,790 and 38,867,180Series A Preference Shares, respectively, each ten (10) of which may be consolidated and redesignated into one (1) ordinary share in our capital. During thethree months ended June 30, 2015, 62,833,330 preferred shares were converted, resulting in the issuance of 6,283,333 ordinary shares. The consolidation andredesignation of the Series A Preference Shares currently outstanding would result in an additional 32,818,464 ordinary shares outstanding, resulting insubstantial dilution to shareholders who held our ordinary shares or ADSs representing such ordinary shares prior to the private placement. Although theSeries A Preference Shares do not have voting rights, in general, upon consolidation and redesignation into ordinary shares some of the investors in theprivate placement could then have significant influence over the outcome of any shareholder vote, including the election of directors and the approval ofmergers or other business combination transactions.Pursuant to the securities subscription agreements that we entered into with the investors in the private placement, we agreed to file with the SEC aregistration statement to register the resale of the Series A Preference Shares represented by American Depositary Shares issued in the private placement andthe ordinary shares issuable upon the consolidation and consolidation and redesignation of such Series A Preference Shares. Upon such registration andsubsequent consolidation and redesignation, these securities will become generally available for immediate resale in the public market. The market price ofour ordinary shares could fall as a result of an increase in the number of shares available for sale in the public market. 63Table of ContentsFailure to comply with our obligations under the March 2015 securities subscription agreements could result in our becoming liable for damages tocertain investors under these agreements, including specified liquidated damages, which could be material in amount.Under the terms of the March 2015 securities subscription agreements, we are subject to various obligations, failure to comply with which could resultin our becoming liable to certain investors under these agreement for damages, which could be material in amount.For example, under each of these agreements we have agreed to file and maintain the effectiveness of certain resale registration statements for ADSsrepresenting the ordinary shares underlying the Series A Preference shares we issued and sold under these agreements. Specifically, we have agreed to payliquidated damages to the investors in the respective private placements if (a) the applicable resale registration statements we are required to file are notdeclared effective within 120 days after the closing of the applicable private placement, or (b) after effectiveness and subject to certain specified exceptions,we suspend the use of the applicable registration statement or the registration statement ceases to remain continuously effective as to all the securities forwhich it is required to be effective. We refer to each of these events as a registration default. Subject to the specified exceptions, for each 30-day period orportion thereof during which a registration default remains uncured, we are obligated to pay liquidated damages to each investor in cash in an amount equalto 1% of the aggregate subscription price paid by each such investor in the private placement, up to a maximum of 8% of such aggregate subscription price.These amounts could be material, and any liquidated damages we are required to pay could have a material adverse effect on our financial condition.In addition, under the securities subscription agreement dated as of March 5, 2015, we are required to offer to certain investors party to that agreementan opportunity to participate in future equity and debt financings we may conduct from time to time, and to not publicly disclose the identity of the investorsparty to that agreement, subject to certain exceptions for disclosures required in securities filings and under applicable law. If we fail to comply with theseobligations we could become liable to these investors for damages, including specified liquidated damages. For example, following certain public statementsmade by us on a quarterly conference call concerning the 2015 private placement, we agreed to specified liquidated damages in the event we are found tohave violated the confidentiality provisions of the subscription agreement in the future.A share price of less than $1.00 may impact our NASDAQ listing.If our closing bid price is less than $1.00 for 30 consecutive trading days, we would receive a NASDAQ staff deficiency letter indicating that we are notin compliance with the minimum bid price requirement for continued listing. Such a letter would trigger an automatic 180 calendar day period within whichthe company could regain compliance. Compliance is regained at any time during this period if the Amarin closing bid price is $1.00 per share or more for aminimum of 10 consecutive trading days. If we do not regain compliance during this period, our ADSs could be delisted from The NASDAQ Global Market,transferred to a listing on The NASDAQ Capital Market, or delisted from the NASDAQ markets altogether. The failure to maintain our listing on TheNASDAQ Global Market could harm the liquidity of our ADSs and could have an adverse effect on the market price of our ADSs.Actual or potential sales of our common shares by our employees, including members of our senior management team, pursuant to pre-arranged stocktrading plans could cause our stock price to fall or prevent it from increasing for numerous reasons, and actual or potential sales by such persons couldbe viewed negatively by other investors.In accordance with the guidelines specified under Rule 10b5-1 of the Securities Exchange Act of 1934 and our policies regarding stock transactions, anumber of our directors and employees, including members of our senior management team, have adopted and may continue to adopt pre-arranged stocktrading plans to sell a portion of our common stock. Generally, sales under such plans by members of our senior management team and 64Table of Contentsdirectors require public filings. Actual or potential sales of our ADSs by such persons could cause the price of our ADSs to fall or prevent it from increasingfor numerous reasons. For example, a substantial amount of our ADSs becoming available (or being perceived to become available) for sale in the publicmarket could cause the market price of our ADSs to fall or prevent it from increasing. Also, actual or potential sales by such persons could be viewednegatively by other investors.We may be a passive foreign investment company, or PFIC, which would result in adverse U.S. federal tax consequences to U.S. investors.Amarin Corporation plc and certain of our subsidiaries may be classified as “passive foreign investment companies,” or PFICs, for U.S. federal incometax purposes. The tests for determining PFIC status for a taxable year depend upon the relative values of certain categories of assets and the relative amountsof certain kinds of income. The application of these factors depends upon our financial results, which are beyond our ability to predict or control, and whichmay be subject to legal and factual uncertainties.We believe it is prudent to assume that we were classified as a PFIC in 2012. We do not believe that we were classified as a PFIC in 2013 through 2016.Our status as a PFIC is subject to change in 2017 and future years.If we are a PFIC, U.S. holders of notes, ordinary shares or ADSs would be subject to adverse U.S. federal income tax consequences, such as ineligibilityfor any preferred tax rates on capital gains or on actual or deemed dividends, interest charges on certain taxes treated as deferred, and additional reportingrequirements under U.S. federal income tax laws and regulations. Whether or not U.S. holders of our ADSs make a timely “QEF election” or “mark-to-marketelection” may affect the U.S. federal income tax consequences to U.S. holders with respect to the acquisition, ownership and disposition of Amarin ADSs andany distributions such U.S. holders may receive. A QEF election and other elections that may mitigate the effect of our being classified as a PFIC areunavailable with respect to the notes. Investors should consult their own tax advisors regarding all aspects of the application of the PFIC rules to the notes,ordinary shares and ADSs.Failure to meet our obligations under our Purchase and Sale Agreement with BioPharma could adversely affect our financial results and liquidity.Pursuant to our December 2012 Purchase and Sale Agreement with BioPharma, we are obligated to make payments to BioPharma based on the amountof our net product sales of Vascepa and any future products based on ethyl-EPA, or covered products, subject to certain quarterly caps.Pursuant to this agreement, we may not, among other things: (i) incur indebtedness greater than a specified amount, which we refer to as theIndebtedness Covenant; (ii) pay a dividend or other cash distribution, unless we have cash and cash equivalents in excess of a specified amount after suchpayment; (iii) amend or restate our memorandum and articles of association unless such amendments or restatements do not affect BioPharma’s interestsunder the transaction; (iv) encumber any of the collateral securing our performance under the agreement; and (v) abandon certain patent rights, in each casewithout the consent of BioPharma.Upon a transaction resulting in a change of control of Amarin, as defined in the agreement, BioPharma will be automatically entitled to receive anyamounts not previously paid, up to our maximum repayment obligation. As defined in the agreement, “change of control” includes, among other things, (i) agreater than 50 percent change in the ownership of Amarin, (ii) a sale or disposition of any collateral securing our debt with BioPharma and (iii), unlessBioPharma has been paid a certain amount under the indebtedness, certain licensings of Vascepa to a third party for sale in the United States. Theacceleration of the payment obligation in the event of a change of control transaction may make us less attractive to potential acquirers, and the payment ofsuch funds out of our available cash or acquisition proceeds would reduce acquisition proceeds for our shareholders. 65Table of ContentsTo secure our obligations under the agreement, we granted BioPharma a security interest in our rights in patents, trademarks, trade names, domainnames, copyrights, know-how and regulatory approvals related to the covered products, all books and records relating to the foregoing and all proceeds of theforegoing, which we refer to as the collateral. If we (i) fail to deliver a payment when due and do not remedy that failure within specific notice period, (ii) failto maintain a first-priority perfected security interest in the collateral in the United States and do not remedy that failure after receiving notice of such failureor (iii) become subject to an event of bankruptcy, then BioPharma may attempt to collect the maximum amount payable by us under this agreement (afterdeducting any payments we have already made).There can be no assurance that we will not breach the covenants or other terms of, or that an event of default will not occur under, this agreement and, ifa breach or event of default occurs, there can be no assurance that we will be able to cure the breach within the time permitted. Any failure to pay ourobligations when due, any breach or default of our covenants or other obligations, or any other event that causes an acceleration of payment at a time whenwe do not have sufficient resources to meet these obligations, could have a material adverse effect on our business, results of operations, financial conditionand future viability.Our existing indebtedness could adversely affect our financial condition.Our existing indebtedness consists of $0.1 million in aggregate principal amount of 3.5% exchangeable senior notes due 2032, or the 2012 Notes, and$30.0 million in aggregate principal amount of 3.5% exchangeable senior notes due 2047, or the 2017 Notes. The 2012 Notes contain a provision for suchnotes to be put to us by the holders for repayment in cash on each of January 19, 2022 and January 19, 2027. The 2017 Notes contain a provision for suchnotes to be put to us by the holders for repayment in cash on January 19, 2022.Our indebtedness and the related annual debt service requirements may adversely impact our business, operations and financial condition in the future.For example, they could: • increase our vulnerability to general adverse economic and industry conditions; • limit our ability to raise additional funds by borrowing or engaging in equity sales in order to fund future working capital, capital expenditures,research and development and other general corporate requirements; • require us to dedicate a substantial portion of our cash to service payments on our debt or to restructure our debt; or • limit our flexibility to react to changes in our business and the industry in which we operate or to pursue certain strategic opportunities that maypresent themselves.The accounting for convertible debt securities that may be settled in cash, such as our 2012 Notes and 2017 Notes, could have a material effect on ourreported financial results.Under the FASB Accounting Standards Codification, or ASC, we are required to separately account for the liability and equity components of theconvertible debt instruments that may be settled entirely or partially in cash upon conversion in a manner that reflects the issuer’s economic interest cost. Theeffect of ASC on the accounting for our outstanding convertible notes may be that the equity component is required to be included in the additional paid-incapital section of stockholders’ equity on our consolidated balance sheets and the value of the equity component would be treated as original issue discountfor purposes of accounting for the debt component of the notes. As a result, we are required to record non-cash interest expense as a result of the amortizationof the discounted carrying value of the notes to their face amount over the term of the notes. We may be required to report higher interest expense in ourfinancial results because ASC may require interest to include both the current period’s amortization of the debt discount and the instrument’s coupon interest,which could adversely affect our reported or future financial results and the trading price of our ADSs. 66Table of ContentsServicing our debt may require a significant amount of cash, and we may not have sufficient cash flow from our business to provide the funds sufficientto pay our substantial debt.Our ability to make scheduled payments of the principal, to pay interest on or to refinance our indebtedness, including the notes, depends on our futureperformance, which is subject to economic, financial, competitive and other factors beyond our control. Our business may not continue to generate cash flowfrom operations in the future sufficient to service our debt and make necessary capital expenditures. If we are unable to generate such cash flow, we may berequired to adopt one or more alternatives, such as selling assets, restructuring debt or obtaining additional equity capital on terms that may be onerous orhighly dilutive. Our ability to refinance our indebtedness will depend on the capital markets and our financial condition at such time. We may not be able toengage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations, including the notes,and have a material adverse effect on the trading price of our ADSs.We may be able to incur substantial additional debt in the future, subject to the restrictions contained in our future debt instruments, if any, whichwould intensify the risks discussed above.We do not intend to pay cash dividends on the ordinary shares in the foreseeable future.We have never paid dividends on ordinary shares and do not anticipate paying any cash dividends on the ordinary shares in the foreseeable future.Under English law, any payment of dividends would be subject to relevant legislation and our Articles of Association, which requires that all dividends mustbe approved by our Board of Directors and, in some cases, our shareholders, and may only be paid from our distributable profits available for the purpose,determined on an unconsolidated basis.The rights of our shareholders may differ from the rights typically offered to shareholders of a U.S. corporation.We are incorporated under English law. The rights of holders of ordinary shares and, therefore, certain of the rights of holders of ADSs, are governed byEnglish law, including the provisions of the Companies Act 2006, and by our Articles of Association. These rights differ in certain respects from the rights ofshareholders in typical U.S. corporations. The principal differences include the following: • Under English law and our Articles of Association, each shareholder present at a meeting has only one vote unless demand is made for a vote ona poll, in which case each holder gets one vote per share owned. Under U.S. law, each shareholder typically is entitled to one vote per share at allmeetings. • Under English law, it is only on a poll that the number of shares determines the number of votes a holder may cast. You should be aware,however, that the voting rights of ADSs are also governed by the provisions of a deposit agreement with our depositary bank. • Under English law, subject to certain exceptions and disapplications, each shareholder generally has preemptive rights to subscribe on aproportionate basis to any issuance of ordinary shares or rights to subscribe for, or to convert securities into, ordinary shares for cash. Under U.S.law, shareholders generally do not have preemptive rights unless specifically granted in the certificate of incorporation or otherwise. • Under English law and our Articles of Association, certain matters require the approval of 75% of the shareholders who vote (in person or byproxy) on the relevant resolution (or on a poll shareholders representing 75% of the ordinary shares voting (in person or by proxy)), includingamendments to the Articles of Association. This may make it more difficult for us to complete corporate transactions deemed advisable by ourboard of directors. Under U.S. law, generally only majority shareholder approval is required to amend the certificate of incorporation or toapprove other significant transactions. 67Table of Contents • In the United Kingdom, takeovers may be structured as takeover offers or as schemes of arrangement. Under English law, a bidder seeking toacquire us by means of a takeover offer would need to make an offer for all of our outstanding ordinary shares/ADSs. If acceptances are notreceived for 90% or more of the ordinary shares/ADSs under the offer, under English law, the bidder cannot complete a “squeeze out” to obtain100% control of us. Accordingly, acceptances of 90% of our outstanding ordinary shares/ADSs will likely be a condition in any takeover offer toacquire us, not 50% as is more common in tender offers for corporations organized under Delaware law. By contrast, a scheme of arrangement, thesuccessful completion of which would result in a bidder obtaining 100% control of us, requires the approval of a majority of shareholders votingat the meeting and representing 75% of the ordinary shares voting for approval. • Under English law and our Articles of Association, shareholders and other persons whom we know or have reasonable cause to believe are, orhave been, interested in our shares may be required to disclose information regarding their interests in our shares upon our request, and the failureto provide the required information could result in the loss or restriction of rights attaching to the shares, including prohibitions on certaintransfers of the shares, withholding of dividends and loss of voting rights. Comparable provisions generally do not exist under U.S. law. • The quorum requirement for a shareholders’ meeting is a minimum of two shareholders entitled to vote at the meeting and present in person or byproxy or, in the case of a shareholder which is a corporation, represented by a duly authorized officer. Under U.S. law, a majority of the shareseligible to vote must generally be present (in person or by proxy) at a shareholders’ meeting in order to constitute a quorum. The minimumnumber of shares required for a quorum can be reduced pursuant to a provision in a company’s certificate of incorporation or bylaws, buttypically not below one-third of the shares entitled to vote at the meeting.U.S. shareholders may not be able to enforce civil liabilities against us.We are incorporated under the laws of England and Wales, and our subsidiaries are incorporated in various jurisdictions, including foreignjurisdictions. A number of the officers and directors of each of our subsidiaries are non-residents of the United States, and all or a substantial portion of theassets of such persons are located outside the United States. As a result, it may not be possible for investors to affect service of process within the UnitedStates upon such persons or to enforce against them judgments obtained in U.S. courts predicated upon the civil liability provisions of the federal securitieslaws of the United States. We have been advised by our English solicitors that there is doubt as to the enforceability in England in original actions, or inactions for enforcement of judgments of U.S. courts, of civil liabilities to the extent predicated upon the federal securities laws of the United States.U.S. holders of the ADSs or ordinary shares may be subject to U.S. federal income taxation at ordinary income tax rates on undistributed earnings andprofits.There is a risk that we will be classified as a controlled foreign corporation, or CFC, for U.S. federal income tax purposes. If we are classified as a CFC,any ADS holder or shareholder that is a U.S. person that owns directly, indirectly or by attribution, 10% or more of the voting power of our outstanding sharesmay be subject to U.S. income taxation at ordinary income tax rates on all or a portion of our undistributed earnings and profits attributable to “subpart Fincome.” Such 10% holder may also be taxable at ordinary income tax rates on any gain realized on a sale of ordinary shares or ADS, to the extent of ourcurrent and accumulated earnings and profits attributable to such shares. The CFC rules are complex and U.S. holders of the ordinary shares or ADSs are urgedto consult their own tax advisors regarding the possible application of the CFC rules to them in their particular circumstances. Item 1B.Unresolved Staff CommentsNone. 68Table of ContentsItem 2.PropertiesThe following table lists the location, use and ownership interest of our principal properties as of February 20, 2017: Location Use Ownership Size (sq. ft.) Dublin, Ireland Offices Leased 270 Bedminster, New Jersey, USA Offices Leased 21,963 Effective November 1, 2011, we leased 320 square feet of office space in Dublin, Ireland. The office space was subsequently reduced to 270 square feet,effective November 1, 2013. The lease terminates on October 31, 2017 and may be renewed annually.Effective July 1, 2011, we leased 9,747 square feet of office space in Bedminster, New Jersey. The lease, as amended, terminates on March 31, 2018,and may also be terminated with six months prior notice. On December 6, 2011 we leased an additional 2,142 square feet of space in the same location. OnDecember 15, 2012 and May 8, 2013, we leased an additional 2,601 and 10,883 square feet of space, respectively, in the same location. In January 2014 andApril 2014, we entered into separate transactions with the landlord of this property to vacate approximately 2,142 and 2,000 square feet of space in exchangefor discounts on contractual future rent payments. In January 2015, we signed an agreement to sublease approximately 4,700 square feet of this property to athird party, effective April 1, 2015. Additionally, in June 2015, we executed an agreement to sublease approximately 2,500 square feet of this property to aseparate third party, effective June 16, 2015. On December 15, 2016, we leased an additional 732 square feet of space in the same location, effectiveJanuary 1, 2017.We believe our existing facilities are adequate for our current needs and that additional space will be available in the future on commerciallyreasonable terms as needed. Item 3.Legal ProceedingsIn September and October 2016, we received paragraph IV certification notices from four companies contending to varying degrees that certain of ourpatents are invalid, unenforceable and/or will not be infringed by the manufacture, use, sale or offer for sale of a generic form of Vascepa as described in thosecompanies’ abbreviated new drug applications, or ANDAs. We filed patent infringement lawsuits against three of these four ANDA applicants. In October2016, Amarin filed a lawsuit against Roxane Laboratories, Inc. and related parties (collectively, “Roxane”) in the U.S. District Court for the District ofNevada. The case against Roxane is captioned Amarin Pharma, Inc. et al. v. Roxane Laboratories, Inc. et al., Civ. A. No. 2:16-cv-02525 (D. Nev.). InNovember 2016, Amarin filed a lawsuit against Dr. Reddy’s Laboratories, Inc. and Dr. Reddy’s Laboratories, Ltd. (collectively, “DRL”) in the U.S. DistrictCourt for the District of Nevada. The case against DRL is captioned Amarin Pharma, Inc. et al. v. Dr. Reddy’s Laboratories, Inc. et al., Civ. A. No.2:16-cv-02562 (D. Nev.). In November 2016, Amarin filed a lawsuit against Teva Pharmaceuticals USA, Inc. and Teva Pharmaceuticals Industries Limited(collectively, “Teva”) in the U.S. District Court for the District of Nevada. The case against Teva is captioned Amarin Pharma, Inc. et al. v. TevaPharmaceuticals USA, Inc. et al., Civ. A. No. 2:16-cv-02658. In all three lawsuits, Amarin is seeking, among other remedies, an order enjoining eachdefendant from marketing generic versions of Vascepa before the last to expire of the asserted patents in 2030. The three lawsuits have been consolidated forpretrial proceedings, and are in their early stages. As a result of the statutory stay associated with the filing of these lawsuits under the Hatch-Waxman Act, theFDA cannot grant final approval to Roxane, DRL, or Teva’s respective ANDA before January 2020, unless there is an earlier court decision holding that thesubject patents are not infringed and/or are invalid.The fourth ANDA applicant referenced above is Apotex Inc. (“Apotex”), which sent Amarin a paragraph IV certification notice in September 2016. Thenotice reflected that Apotex made a paragraph IV notice as to some, 69Table of Contentsbut not all, of the patents listed in the Orange Book for Vascepa. Because Apotex did not make a paragraph IV certification as to all listed patents, Apotexcannot market a generic version of Vascepa before the last to expire of the patents for which Apotex did not make a paragraph IV certification, which is in2030. At a later date, Apotex may elect to amend its ANDA in order to make a paragraph IV certification as to additional listed patents. If and when Apotexdoes make such an amendment, it would be required to send Amarin an additional paragraph IV certification notice, and Amarin would then have the abilityto file a lawsuit against Apotex pursuant to the Hatch-Waxman Act.We intend to vigorously enforce our intellectual property rights relating to Vascepa, but we cannot predict the outcome of the Roxane, DRL or Tevalawsuits or any subsequently filed lawsuits.On April 26, 2016, the U.S. District Court for the District of New Jersey granted our motion to dismiss the putative consolidated class action lawsuitcaptioned In re Amarin Corporation plc, Securities Litigation, No. 3:13-cv-06663 (D.N.J. Nov. 1, 2013). The class action was dismissed without prejudicewith leave for plaintiffs to file an amended complaint. The lawsuit seeks unspecified monetary damages and attorneys’ fees and costs alleging that we andcertain of our current and former officers and directors made misstatements and omissions regarding the FDA’s willingness to approve Vascepa’s ANCHORindication and related contributing factors and the potential relevance of data from the ongoing REDUCE-IT trial to that potential approval. The April 2016dismissal was the second motion to dismiss granted in favor of Amarin and related defendants in this litigation. The first motion to dismiss in this litigationwas granted in June 2015 in response to the original complaint and related amendment.On May 24, 2016, plaintiffs notified the court that they would not file another amended complaint and, on May 26, 2016, filed a notice of appeal ofthe most recent dismissal to the Third Circuit Court of Appeals. Plaintiffs filed their appellate brief on September 21, 2016, we filed an opposition brief onNovember 29, 2016, and plaintiffs filed their reply on December 29, 2016. No hearing date has been set. We plan a vigorous defense to this appeal. We haveinsurance coverage that is anticipated to cover any significant loss exposure that may arise from this action.In addition to the above, in the ordinary course of business, we are from time to time involved in lawsuits, claims, investigations, proceedings, andthreats of litigation relating to intellectual property, commercial arrangements and other matters. Item 4.Mine Safety DisclosuresNot applicable. 70Table of ContentsPART II Item 5.Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity SecuritiesMarket InformationThe following table sets forth the high and low prices for our ADSs in each of the quarters over the past two fiscal years, as quoted on The NASDAQGlobal Market. Common Stock Price Fiscal 2016 Fiscal 2015 High Low High Low First Quarter $1.88 $1.24 $3.33 $0.98 Second Quarter $2.35 $1.45 $2.80 $1.82 Third Quarter $3.46 $2.11 $2.59 $1.58 Fourth Quarter $3.65 $2.75 $2.19 $1.79 ShareholdersAs of January 31, 2017, there were approximately 380 holders of record of our ordinary shares. Because many ordinary shares are held by brokernominees, we are unable to estimate the total number of shareholders represented by these record holders. Our depositary, Citibank, N.A., constitutes a singlerecord holder of our ordinary shares.DividendsWe have never paid dividends on common shares and do not anticipate paying any cash dividends on the common shares in the foreseeable future.Under English law, any payment of dividends would be subject to relevant legislation and our Articles of Association, which requires that all dividends mustbe approved by our Board of Directors and, in some cases, our stockholders, and may only be paid from our distributable profits available for the purpose,determined on an unconsolidated basis.Under our Purchase and Sale Agreement with BioPharma Secured Debt Fund II Holdings Cayman LP, or BioPharma, we are restricted from paying adividend on our common shares, unless we have cash and cash equivalents in excess of a specified amount after such payment. 71Table of ContentsPerformance Graph—5 YearThe following performance graph and related information shall not be deemed “soliciting material” or to be “filed” with the Securities andExchange Commission, nor shall such information be incorporated by reference into any future filing under the Securities Act of 1933 or SecuritiesExchange Act of 1934, each as amended, except to the extent that we specifically incorporate it by reference into such filing.The following graph compares the cumulative 5-year return provided to stockholders of Amarin’s ADSs relative to the cumulative total returns of theNASDAQ Composite Index and the NASDAQ Biotechnology Index. We believe these indices are the most appropriate indices against which the totalshareholder return of Amarin should be measured. The NASDAQ Biotechnology Index has been selected because it is an index of U.S. quoted biotechnologyand pharmaceutical companies. An investment of $100 (with reinvestment of all dividends) is assumed to have been made in our ADSs and in each of theindices on January 1, 2012 and its relative performance is tracked through December 31, 2016.Included in this 5-year time period is the substantial negative impact on the price of Amarin’s ADSs in 2013 when the FDA notified us that it rescindedthe ANCHOR study SPA agreement because the FDA determined that a substantial scientific issue essential to determining the effectiveness of Vascepa in thestudied population was identified after testing began in the ANCHOR trial. The FDA expressed that this scientific issue arose based on data from the study ofother drugs by other companies related to lipid modification. This FDA notification was followed in 2013 by a reduction in force by Amarin and retargetingof the commercial targets for promotion of Vascepa. More recently, over the 3-year time period through December 31, 2016, cumulative total return forAmarin’s ADSs exceeded both the NASDAQ Composite Index and NASDAQ Biotechnology Index. In particular, the total return for Amarin’s ADSs wellexceeded the cumulative returns for the NASDAQ Composite Index and NASDAQ Biotechnology Index in each of the past two calendar years.

Where these conditions are not met, the transfer of, or agreement totransfer, an ADS could, depending on the circumstances, attract a charge to ad valorem stamp duty at the rate of 0.5% of the value of the consideration.No stamp duty reserve tax will be payable in respect of an agreement to transfer an ADS, whether made in or outside the UK.Issue and Transfer of Common SharesThe issue of common shares by Amarin will not give rise to a charge to UK stamp duty or stamp duty reserve tax under current UK and European Unionlaw; it is not currently known whether this position will continue for UK stamp duty reserve tax in relation to the issue of common shares in return for an issueof ADSs after the United Kingdom leaves the European Union. In the event of a change in this position resulting in the issue of common shares by Amaringiving rise to a charge to UK stamp duty or stamp duty reserve tax, Amarin would be responsible for any such UK stamp duty reserve tax payable on the issueof common shares in return for the issue of ADSs. 74Table of ContentsTransfers of common shares, as opposed to ADSs, will attract ad valorem stamp duty at the rate of 0.5% of the amount or value of the consideration. Acharge to stamp duty reserve tax, at the rate of 0.5% of the amount or value of the consideration, will arise on an agreement to transfer common shares. Thestamp duty reserve tax is payable on the seventh day of the month following the month in which the charge arises. Where an instrument of transfer isexecuted and duly stamped before the expiry of a period of six years beginning with the date of that agreement, any stamp duty reserve tax that has not beenpaid ceases to be payable.Taxation of DividendsUnder UK law, there is no withholding tax on dividends paid on the common shares or ADSs.

Item 7.Management’s Discussion and Analysis of Financial Condition and Results of OperationsThis Annual Report on Form 10-K contains forward-looking statements concerning future events and performance of the Company. When used in thisreport, the words “may,” “would,” “should,” “could,” “expects,” “aims,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” “projects,”“potential,” or “continue” or the negative of these terms or other comparable terminology are included to identify forward-looking statements. Thesestatements include but are not limited to statements regarding the commercial success of Vascepa and factors that can affect such success; interpretation ofcourt decisions; expectation on determinations and policy positions of the United States Food and Drug Administration, or FDA; the expected timing ofenrollment, interim results and final results of our REDUCE-IT study; the safety and efficacy of our product and product candidates; expectation regardingthe potential for Vascepa to be partnered, developed and commercialized outside of the United States; expectation on the scope and strength of ourintellectual property protection and the likelihood of securing additional patent protection; estimates of the potential markets for our product candidates;estimates of the capacity of manufacturing and other facilities to support our products; our operating and growth strategies; our industry; our projectedcash needs, liquidity and capital resources; and our expected future revenues, operations and expenditures. These forward-looking statements are based onour current expectations and assumptions and many factors could cause our actual results to differ materially from those indicated in these forward-looking statements. You should review carefully the factors identified in this report in Item 1A, “Risk Factors”. We disclaim any intent to update orannounce revisions to any forward-looking statements to reflect actual events or developments, except as required by law. Except as otherwise indicatedherein, all dates referred to in this report represent periods or dates fixed with reference to our fiscal year ended December 31, 2016.OverviewWe are a biopharmaceutical company with expertise in lipid science focused on the commercialization and development of therapeutics to improvecardiovascular health. 76Table of ContentsOur lead product, Vascepa (icosapent ethyl) capsules, is approved by the U.S. Food and Drug Administration, or FDA, for use as an adjunct to diet toreduce triglyceride levels in adult patients with severe (TG 500 mg/dL) hypertriglyceridemia. This FDA-approved indication for Vascepa, known as theMARINE indication, is based primarily on the successful results from the MARINE study of Vascepa in this approved patient population. In considering thisapproval, FDA also reviewed the successful results from our study of Vascepa in patients with high triglyceride levels (TG 200 mg/dL and <500 mg/dL)who are also on statin therapy for elevated low-density lipoprotein cholesterol, or LDL-C, levels which condition we refer to as mixed dyslipidemia orpersistently high triglycerides. This study is known as the ANCHOR study. Safety data from both the MARINE and ANCHOR studies are reflected inFDA-approved labeling for Vascepa. In January 2013, we began selling and marketing Vascepa in the United States based on the FDA-approved MARINEindication. In August 2015, we also began communicating promotional information beyond the MARINE indication to healthcare professionals in theUnited States based on the federal court declaration described below. In March 2016, we reached agreement with the FDA and U.S. government under whichthey agreed to be bound by the terms of the August 2015 judicial declaration. Vascepa is available in the United States by prescription only.We sell Vascepa principally to a limited number of major wholesalers, as well as selected regional wholesalers and specialty pharmacy providers, orcollectively, our Distributors or our customers, that in turn resell Vascepa to retail pharmacies for subsequent resale to patients and healthcare providers. Wemarket Vascepa in the United States through our direct sales force of approximately 150 sales professionals, including sales representatives and theirmanagers. In March 2014, we entered into a co-promotion agreement in the United States with Kowa Pharmaceuticals America, Inc. under which no less than250 Kowa Pharmaceuticals America, Inc. sales representatives began to devote a substantial portion of their time to promoting Vascepa starting in May 2014.In February 2015, we entered into an exclusive agreement with Eddingpharm (Asia) Macao Commercial Offshore Limited, or Eddingpharm, to developand commercialize Vascepa capsules in Mainland China, Hong Kong, Macau and Taiwan, or the China Territory. In March 2016, we entered into anagreement with Biologix FZCo, or Biologix, to register and commercialize Vascepa in countries within the Middle East and North Africa. We continue toassess other partnership opportunities for licensing Vascepa to partners outside of the United States.Triglycerides are the main constituent of body fat humans. Hypertriglyceridemia refers to a condition in which patients have high levels oftriglycerides in the bloodstream. It is estimated that over 70 million adults in the United States have elevated triglyceride levels (TG 150 mg/dL),approximately 40 million adults in the United States have high triglyceride levels (TG 200 mg/dL), and approximately 4.0 million people in the UnitedStates have severely high triglyceride levels (TG 500 mg/dL), commonly known as very high triglyceride levels. Many patients with high triglyceridelevels also have diabetes and other lipid level abnormalities such as high cholesterol. The patient condition of having more than one lipid level abnormalityis referred to as mixed dyslipidemia. According to The American Heart Association Scientific Statement on Triglycerides and Cardiovascular Disease(2011), triglycerides provide important information as a marker associated with the risk for heart disease and stroke, especially when an individual also haslow high-density lipoprotein cholesterol, or HDL-C (often referred to as “good” cholesterol), and elevated levels of LDL-C (often referred to as “bad”cholesterol). Guidelines for the management of very high triglyceride levels suggest that reducing triglyceride levels is the primary goal in patients to reducethe risk of acute pancreatitis. The effect of Vascepa on cardiovascular mortality and morbidity, or the risk for pancreatitis, in patients withhypertriglyceridemia has not been determined.We are currently focused on completing the ongoing REDUCE-IT (Reduction of Cardiovascular Events with EPA—Intervention Trial) cardiovascularoutcomes study of Vascepa, which we started in December 2011. REDUCE-IT, a multinational, prospective, randomized, double-blind, placebo-controlledstudy, is the first prospective cardiovascular outcomes study of any drug in a population of patients who, despite stable statin therapy, have elevatedtriglyceride levels. Based on the results of REDUCE-IT, we plan to seek additional 77®Table of Contentsindicated uses for Vascepa. In REDUCE-IT, cardiovascular event rates for patients on stable statin therapy plus 4 grams per day of Vascepa will be comparedto cardiovascular event rates for patients on stable statin therapy plus placebo. In 2016, we completed patient enrollment and randomization of 8,175individual patients into the REDUCE-IT study, exceeding the 8,000 patients targeted for the trial.The REDUCE-IT study is designed to be completed after reaching 1,612 aggregate primary cardiovascular events. Based on projected event rates, weestimate the onset of the target aggregate number of cardiovascular events to be reached near the end of 2017 with study results then expected to be availableand published in 2018. In addition, since its inception in 2011, our REDUCE-IT special protocol assessment (SPA) agreement with the FDA has provided forperiodic safety reviews and an interim efficacy and safety analysis by the study’s independent data monitoring committee (DMC) at approximately 60% ofthe target aggregate number of primary cardiovascular events. In August 2016, we announced an amendment to our REDUCE-IT SPA agreement with FDAthat reaffirmed FDA concurrence on key elements of the study, defined details of the statistical analysis plan for the study, expanded to greater than 30 thepre-specified secondary and tertiary endpoints in the study, and added a second interim efficacy and safety analysis by the DMC at approximately 80% of thetarget aggregate number of primary cardiovascular events. The periodic safety reviews and interim efficacy and safety analyses are conducted confidentiallyby the study’s DMC. We remain blinded to all data from the study. Since patient enrollment commenced in 2011, more than 26,000 patient years of studyexperience have been accumulated in the REDUCE-IT study. Following each periodic review of safety data to date, the DMC has communicated to us that weshould continue the study as planned.In March 2016, we announced that the onset of approximately 60% of the target aggregate number of primary cardiovascular events had triggeredpreparation for the first pre-specified interim analysis of efficacy and safety results. Such analysis included the first review of unblinded efficacy data by theindependent DMC. The DMC completed its review of the interim analysis in September 2016 and, consistent with previously stated expectations,recommended that the trial continue as planned without modification. The second planned interim analysis of efficacy results will be triggered by the onsetof approximately 80% of the target aggregate number of primary cardiovascular events in the study. Based on historical event rates, we anticipate that theonset of approximately 80% of events will occur in the first half of 2017, with the second pre-specified interim efficacy analysis by the DMC expected in orabout the third quarter of 2017. The interim efficacy analysis will be accompanied by an interim safety analysis by the DMC. As is typical, the statisticalthreshold for defining overwhelming efficacy on the primary endpoint at interim analyses is considerably higher than the threshold for defining statisticalsignificance at the end of the study. In addition, we have requested the DMC to not recommend stopping the study early based only upon the achievement ofstatistical significance for the primary endpoint, but to ensure that supportive trends of benefit are also consistently observed in certain secondary endpointsand subpopulations before recommending that the study be stopped early for overwhelming efficacy. This is the same approach we asked the DMC to employin connection with the REDUCE-IT study 60% interim analysis. It is our expectation that the 80% interim analysis will also result in a recommendation bythe DMC to continue the trial.In the successful Phase 3 MARINE and ANCHOR clinical trials, Vascepa was studied at a daily dose of 2 grams and 4 grams. We sought approval ofVascepa at the more efficacious 4-gram dose for use in each patient population. These trials demonstrated favorable results in their respective patientpopulations, particularly with the 4-gram dose of Vascepa, in reducing triglyceride levels without increasing LDL-C levels in the MARINE trial and with astatistically significant decrease in LDL-C levels in the ANCHOR trial, in each case, relative to placebo. These trials also showed favorable results,particularly with the 4-gram dose of Vascepa, in other important lipid and inflammation biomarkers, including apolipoprotein B (apo B), non-high-densitylipoprotein cholesterol (non-HDL-C), total-cholesterol (TC), very low-density lipoprotein cholesterol (VLDL-C), lipoprotein-associated phospholipase A2(Lp-PLA2), and high sensitivity C-reactive protein (hs-CRP). In these trials, the most commonly reported adverse reaction (incidence >2% and greater thanplacebo) in Vascepa-treated patients was arthralgia (joint pain) (2.3% for Vascepa vs. 1.0% for placebo). 78Table of ContentsIn April 2015, we received a Complete Response Letter, or CRL, from the FDA in response to our supplemental new drug application, or sNDA, thatsought approval of Vascepa for use in patients with mixed dyslipidemia, based on the successful ANCHOR study. The CRL followed an October 2013rescission by the FDA of a special protocol assessment, or SPA, agreement and three failed attempts by us to appeal that rescission at FDA. The FDA hasacknowledged the success of the ANCHOR study, which met all primary and secondary endpoints. However, FDA determined that there were insufficient datato conclude that drug-induced changes in serum triglycerides could be recognized by the FDA as a valid surrogate for reducing cardiovascular risk in theANCHOR population for the purpose of regulatory approval of a drug targeted at a triglyceride-lowering indication in this population. The FDA hasacknowledged that the standard of proof required by the FDA for approval of a new drug indication is higher than that generally used to inform patienttreatment guidelines and that used by physicians in clinical practice. The FDA did not determine that the drug-induced effects of Vascepa, which go beyondtriglyceride-lowering, would not actually reduce cardiovascular risk in this population and the FDA has encouraged us to complete the REDUCE-IToutcomes study. Based on our communications with the FDA, we expect that final positive results from the REDUCE-IT outcomes study will be required forlabel expansion for Vascepa.In May 2015, we and a group of independent physicians filed a lawsuit in federal court to permit us to promote to healthcare professionals the use ofVascepa in patients with mixed dyslipidemia so long as the promotion is truthful and non-misleading. This use reflects recognized medical practice but is notcovered by current FDA-approved labeling for the drug. Historically, FDA has considered promotion of drug uses not covered by FDA approved labelling tobe illegal off-label promotion, even if such promotion is truthful and non-misleading. In August 2015, we were granted preliminary relief in the form of adeclaratory judgment in this lawsuit. The court declaration permits us to promote to healthcare professionals the FDA-reviewed and agreed effects of Vascepademonstrated in the ANCHOR clinical trial and presentation of the current state of scientific research related to the potential of Vascepa to reduce the risk ofcardiovascular disease including through use of peer-reviewed scientific publications of available data. In August 2015, we began to communicatepromotional information beyond the MARINE indication to healthcare professionals in the United States as permitted by this court declaration and in March2016, the parties obtained court approval of negotiated settlement terms under which the FDA and the U.S. government agreed to be bound by the court’sconclusions from the August 2015 declaration that we may engage in truthful and non-misleading speech promoting the off-label use of Vascepa and thatcertain statements and disclosures that we proposed to make to healthcare professionals were truthful and non-misleading. While we believe we are nowpermitted under applicable law to more broadly promote Vascepa, the FDA-approved labeling for Vascepa did not change, as a result of this litigation andsettlement, and neither government nor other third-party coverage or reimbursement to pay for the off-label use of Vascepa promoted under the courtdeclaration was required.Commercialization—United StatesWe commenced the commercial launch of 1-gram size Vascepa capsules in the United States in January 2013. We commenced sales and shipments ofVascepa at that time to our network of U.S.-based wholesalers. We currently market Vascepa in the United States through our direct sales force ofapproximately 150 sales professionals, including sales representatives and their managers. Commencing in May 2014, in addition to Vascepa promotion byour sales representatives, no less than 250 Kowa Pharmaceuticals America, Inc. sales representatives began devoting a substantial portion of their time topromoting Vascepa. We also employ various marketing personnel to support our commercialization of Vascepa. In October 2016, in addition to the original1-gram capsule size for Vascepa, we introduced a smaller 0.5-gram capsule size, the first and only 0.5-gram prescription omega-3 alternative available on themarket, for the subset of patients who prefer a smaller capsule. The FDA-approved dosing for Vascepa continues to be 4 grams per day, and we expect that themajority of patients taking Vascepa will continue to be prescribed the 1-gram size Vascepa capsule. We also expect that the majority of new patients will beprescribed the 1-gram size Vascepa capsule.Under our co-promotion agreement with Kowa Pharmaceuticals America, Inc., both parties have agreed to use commercially reasonable efforts topromote, detail and optimize sales of Vascepa in the United States and 79Table of Contentshave agreed to specific performance requirements detailed in the related agreement. The performance requirements include a negotiated minimum number ofsales details to be delivered by each party in the first and second position, the use of a negotiated number of minimum sales representatives from each party,including no less than 250 Kowa Pharmaceuticals America, Inc. sales representatives and the achievement of minimum levels of Vascepa revenue in 2015and beyond. First position refers to when a sales representative’s primary purpose in detailing is related to Vascepa, while second position refers to when asales representative’s primary purpose in detailing is to promote another product, but they also devote time in the same sales call to promote Vascepa. KowaPharmaceuticals America, Inc. has also agreed to continue to bear the costs incurred for its sales force associated with the commercialization of Vascepa andto pay for certain incremental costs associated with the use of its sales force, such as sample costs and costs for promotional and marketing materials. We willcontinue to recognize all revenue from sales of Vascepa. In exchange for Kowa Pharmaceuticals America, Inc.’s co-promotional services, KowaPharmaceuticals America, Inc. is entitled to a quarterly co-promotion fee based on a percentage of aggregate Vascepa gross margin that increases during theterm. The percentage of aggregate Vascepa gross margin earned by Kowa Pharmaceuticals America, Inc. was fifteen percent (15%) in 2015, was nineteenpercent (19%) in 2016, and is scheduled to increase to the low twenty percent levels in 2017 and 2018, subject to certain adjustments. The term of thisco-promotion agreement expires on December 31, 2018, following which our agreement with Kowa Pharmaceuticals America, Inc. provides for up to threeyears of tail royalties equal to declining percentages of the co-promotion fee earned prior to agreement expiration.Based on monthly compilations of data provided by a third party, Symphony Health Solutions, the estimated number of normalized total Vascepaprescriptions for the three months ended December 31, 2016 was approximately 286,000 compared to 260,000, 230,000, 201,000, and 191,000 in the threemonths ended September 30, 2016, June 30, 2016, March 31, 2016, and December 31, 2015, respectively. According to data from another third party, IMSHealth, the estimated number of normalized total Vascepa prescriptions for the three months ended December 31, 2016 was approximately 312,000 comparedto 274,000, 249,000, 216,000, and 203,000 in the three months ended September 30, 2016, June 30, 2016, March 31, 2016, and December 31, 2015,respectively. Normalized total prescriptions represent the estimated total number of Vascepa prescriptions shipped to patients, calculated on a normalizedbasis (i.e., one month’s supply, or total capsules shipped multiplied by the number of grams per capsule divided by 120 grams). Inventory levels atwholesalers tend to fluctuate based on seasonal factors, prescription trends and other factors. During 2016, predominantly in the second quarter, wholesalerinventory levels increased based on estimated days of inventory on hand. In addition, regional stocking of Vascepa expanded at certain retail pharmacies,likely due to higher volume sales of Vascepa.The data reported above is based on information made available to us from third-party resources and may be subject to adjustment and may overstate orunderstate actual prescriptions. Timing of shipments to wholesalers, as used for revenue recognition purposes, and timing of prescriptions as estimated bythese third parties may differ from period to period. Although we believe these data are prepared on a period-to-period basis in a manner that is generallyconsistent and that such results can be generally indicative of current prescription trends, these data are based on estimates and should not be relied upon asdefinitive. While we expect to be able to grow Vascepa revenues over time, no guidance should be inferred from the operating metrics described above. Wealso anticipate that such sales growth will be inconsistent from period to period. We believe that investors should view the above-referenced operatingmetrics with caution, as data for this limited period may not be representative of a trend consistent with the results presented or otherwise predictive of futureresults. Seasonal fluctuations in pharmaceutical sales, for example, may affect future prescription trends of Vascepa, as could changes in prescriber sentiment,quarterly changes in Distributor purchases, and other factors. These fluctuations from multiple variables make it difficult to predict quarterly prescriptiontrends and product revenues on a consistent basis. We believe investors should consider our results over several quarters, or longer, before making anassessment about potential future performance.The commercialization of pharmaceutical products is a complex undertaking, and our ability to effectively and profitably commercialize Vascepa willdepend in part on our ability to generate market demand for Vascepa through education, marketing and sales activities, our ability to achieve marketacceptance of Vascepa, our 80Table of Contentsability to generate product revenue and our ability to receive adequate levels of reimbursement from third-party payers. See “Risk Factors—Risks Related tothe Commercialization and Development of Vascepa.”In August 2015, we and our co-promotion partner began communicating promotional information beyond MARINE clinical trial data to targetedhealthcare professionals. Such qualified communications are being made pursuant to the August 7, 2015 federal district court declaration and related March2016 settlement allowing truthful and non-misleading promotion of the FDA-reviewed and agreed effects of Vascepa demonstrated in the ANCHOR clinicaltrial and presentation of the current state of scientific research related to the potential of Vascepa to reduce the risk of cardiovascular disease includingthrough use of peer-reviewed scientific publications of available data.Commercialization—Outside the United StatesIn February 2015, we announced an exclusive agreement with Eddingpharm to develop and commercialize Vascepa capsules in what we refer to as theChina Territory, consisting of the territories of Mainland China, Hong Kong, Macau and Taiwan, for uses that are currently commercialized and underdevelopment by us in the United States based on the MARINE, ANCHOR and ongoing REDUCE-IT clinical trials of Vascepa.Under the agreement, Eddingpharm is responsible for development and commercialization activities in the China Territory and associated expenses.We will provide development assistance and be responsible for supplying the product. Terms of the agreement include up-front and milestone payments to usof up to $169.0 million, including a non-refundable $15.0 million up-front payment received at closing, a non-refundable milestone payment of $1.0 millionreceived upon successful submission of a clinical trial application with respect to the MARINE indication for Vascepa to the Chinese regulatory authority inMarch 2016, and future regulatory and sales-based milestone payments of up to an additional $153.0 million. The regulatory milestone events relate to thesubmission and approval of certain applications to the applicable regulatory authority, such as a clinical trial application, clinical trial exemption, or importdrug license application. The amounts to be received upon achievement of the regulatory milestone events relate to the submission and approval for threeindications, and range from $1.0 million to $15.0 million for a total of $33.0 million. The sales-based milestone events occur when annual aggregate net salesof Vascepa in the territory equals or exceeds certain specified thresholds, and range from $5.0 million to $50.0 million for a total of $120.0 million.Eddingpharm will also pay us tiered double-digit percentage royalties on net sales of Vascepa in the China Territory escalating to the high teens. We willsupply finished product to Eddingpharm under negotiated terms.In March 2016, we entered into an agreement with Biologix to register and commercialize Vascepa in several Middle Eastern and North Africancountries. Under the terms of the distribution agreement, we granted to Biologix a non-exclusive license to use our trademarks in connection with theimportation, distribution, promotion, marketing and sale of Vascepa in the Middle East and North Africa territory. Upon closing of the agreement, wereceived a non-refundable up-front payment, which will be recognized as revenue over 10 years commencing upon first marketing approval of Vascepa in theterritory. We are entitled to receive payments based on product sales at an agreed-upon transfer price, which represents a percentage of gross selling price,subject to a minimum floor price.We continue to assess other partnership opportunities for licensing Vascepa to partners outside of the United States.Research and DevelopmentREDUCE-IT is the first prospective cardiovascular outcomes study of any drug in a population of patients who, despite stable statin therapy, haveelevated triglyceride levels. REDUCE-IT is a multinational, prospective, randomized, double-blind, placebo-controlled study designed to assess thecumulative effect on the rate of cardiovascular events for patients treated with Vascepa as an add-on to statin therapy compared to the 81Table of Contentscorresponding rate of cardiovascular events for patients treated with placebo on top of statin therapy. REDUCE-IT is not designed to demonstrate thatlowering triglycerides alone in the study population is sufficient to lower the rate of major adverse cardiovascular events compared to placebo. Rather, it isdesigned to demonstrate that clinical effects of Vascepa, including its impact on triglyceride lowering, is effective in lowering the rate of major adversecardiovascular events compared to placebo in patients who despite statin therapy have risk factors for cardiovascular disease, including elevated triglyceridelevels. Based on the results of REDUCE-IT, we may seek additional indications for Vascepa beyond the indications studied in the ANCHOR or MARINEtrials.In 2016, we completed patient enrollment and randomization of 8,175 individual patients into the REDUCE-IT study, exceeding the 8,000 patientstargeted for the trial.Completion of the REDUCE-IT study is designed to occur after reaching an aggregate number of cardiovascular events. Based on projected event rates,we estimate the onset of the target aggregate number of cardiovascular events to be reached near the end of 2017 with study results then expected to beavailable in 2018. In addition, since its inception in 2011, our REDUCE-IT SPA agreement with the FDA has provided for periodic safety reviews and aninterim efficacy and safety analysis by the independent DMC at approximately 60% of the target aggregate number of primary cardiovascular events. InAugust 2016, we announced an amendment to our REDUCE-IT SPA agreement with FDA that reaffirmed FDA concurrence on key elements of the study,defined details of the statistical analysis plan for the study, expanded to greater than 30 the pre-specified secondary and tertiary endpoints in the study, andadded a second interim efficacy and safety analysis by the DMC at approximately 80% of the target aggregate number of primary cardiovascular events.In March 2016, we announced that the onset of approximately 60% of the target aggregate number of primary cardiovascular events had triggeredpreparation for the first pre-specified interim analysis of efficacy and safety results. Such analysis included the first review of unblinded efficacy data by theindependent DMC. The DMC completed its review of the interim analysis in September 2016 and, consistent with previously stated expectations,recommended that the trial continue as planned without modification. The second planned interim analysis of efficacy results will be triggered by the onsetof approximately 80% of the target aggregate number of primary cardiovascular events in the study. Based on historical event rates, we anticipate that theonset of approximately 80% of events will occur in the first half of 2017, with the second pre-specified interim efficacy analysis by the DMC expected in orabout the third quarter of 2017. The interim efficacy analysis will be accompanied by an interim safety analysis by the DMC. As is typical, the statisticalthreshold for defining overwhelming efficacy on the primary endpoint at interim analyses is considerably higher than the threshold for defining statisticalsignificance at the end of the study. In addition, we have requested the DMC to not recommend stopping the study early based only upon the achievement ofstatistical significance for the primary endpoint, but to ensure that supportive trends of benefit are also consistently observed in certain secondary endpointsand subpopulations before recommending that the study be stopped early for overwhelming efficacy. This is the same approach we asked the DMC to employin connection with the REDUCE-IT study 60% interim analysis. It is our expectation that the 80% interim analysis will also result in a recommendation bythe DMC to continue the trial. By design, it is most common for cardiovascular outcomes studies not to be stopped upon an interim look. We remain blindedto all data from the study. Unless overwhelming efficacy and safety is declared by the DMC at an interim look or the study is halted due to a patient safetyconcern, Amarin personnel will remain blinded to the efficacy and safety data from the REDUCE-IT study until the study is complete.Since patient enrollment commenced in 2011, more than 26,000 patient years of study experience have been accumulated in REDUCE-IT. The DMChas reviewed unblinded safety data on a quarterly basis since 2013 and, after each such review of unblinded safety data to date, the DMC has recommendedto us that the study be continued as planned.Our scientific rationale for the REDUCE-IT study is supported by (i) epidemiological data that suggests elevated triglyceride levels correlate withincreased cardiovascular disease risk, (ii) genetic data that suggests 82Table of Contentstriglyceride and/or triglyceride-rich lipoproteins (as well as low-density lipoprotein cholesterol (LDL cholesterol), known as bad cholesterol) areindependently in the causal pathway for cardiovascular disease and (iii) clinical data that suggest substantial triglyceride reduction in patients with elevatedbaseline triglyceride levels correlates with reduced cardiovascular risk. Our scientific rationale for the REDUCE-IT study is also supported by research on theputative cardioprotective effects of EPA as presented in scientific literature. It is possible that the effects of EPA may be due not to a single mode of action,such as triglyceride lowering, but rather to multiple mechanisms working together. Studies in the scientific literature explore potentially beneficial effects ofEPA on multiple atherosclerosis processes, including endothelial function, oxidative stress, foam cell formation, inflammation/cytokines, plaqueformation/progression, platelet aggregation, thrombus formation, and plaque rupture. The REDUCE-IT study is needed to determine the clinical benefit, ifany, of EPA therapy in statin-treated patients with elevated triglyceride levels.Commercial SupplyPrior to 2015, all of our active pharmaceutical ingredient, or API, that has been utilized in product sold was manufactured by two suppliers: NisshinPharma, Inc., or Nisshin, and Chemport, Inc., or Chemport. A significant portion of such API was purchased from Nisshin at a price that was higher thanprojected future average API costs. During 2015, we began purchasing API from a third supplier, Finorga SAS, or Novasep. The amount of supply we seek topurchase in future periods will depend on the level of growth of Vascepa revenues and minimum purchase commitments with certain suppliers. While ourcurrent supply chain is scalable, we continue efforts to expand, diversify and further enhance it.Financial PositionWe believe that our cash and cash equivalents of $98.3 million as of December 31, 2016 will be sufficient to fund our projected operations through theresults of the REDUCE-IT study, which we anticipate will be available mid-2018. Depending on the level of cash generated from operations, additionalcapital may be required to sustain operations, fund debt obligations or expand promotion of Vascepa as contemplated following anticipated successfulresults of the REDUCE-IT study. We anticipate that quarterly net cash outflows in future periods will be variable.Financial Operations OverviewProduct Revenue, net. All of our product revenue is derived from product sales of 1-gram and 0.5-gram size capsules of Vascepa, net of allowances,discounts, incentives, rebates, chargebacks and returns. We sell product to a limited number of major wholesalers, as well as selected regional wholesalers andspecialty pharmacy providers, or collectively, our Distributors or our customers, who resell the product to retail pharmacies for purposes of their reselling theproduct to fill patient prescriptions. We commenced our commercial launch of 1-gram size Vascepa capsules in the United States in January 2013, andintroduced a smaller 0.5-gram size capsule in October 2016. In accordance with U.S. Generally Accepted Accounting Principles, or GAAP, during 2013,before we had the ability to reliably estimate returns of Vascepa from our Distributors, revenue was recognized based on the resale of Vascepa for the purposesof filling patient prescriptions, and not based on our sales to such Distributors. In 2014, we concluded that we had developed sufficient history such that wecan reliably estimate returns and as a result, began to recognize revenue based on sales to our Distributors.Licensing revenue. Licensing revenue currently consists of revenue attributable to receipt of up-front, non-refundable payments and milestonepayments related to license and distribution agreements for Vascepa outside the United States. Up-front and milestone payments under such agreements aretypically recognized as licensing revenue over the estimated period in which we are required to provide regulatory and development support and clinical andcommercial supply pursuant to the agreements.Cost of Goods Sold. Cost of goods sold includes the cost of API for Vascepa on which revenue was recognized during the period, as well as theassociated costs for encapsulation, packaging, shipment, supply 83Table of Contentsmanagement, quality assurance, insurance, and other indirect manufacturing, logistics and product support costs. The cost of the API included in cost ofgoods sold reflects the average cost method of inventory valuation and relief. This average cost reflects the actual purchase price of Vascepa API.Selling, General and Administrative Expense. Selling, general and administrative expense consists primarily of salaries and other related costs,including stock-based compensation expense, for personnel in our sales, marketing, executive, business development, finance and information technologyfunctions, as well as co-promotion fees payable to Kowa Pharmaceuticals America, Inc. Other costs primarily include facility costs and professional fees foraccounting, consulting and legal services.Research and Development Expense. Research and development expense consists primarily of fees paid to professional service providers inconjunction with independent monitoring of our clinical trials and acquiring and evaluating data in conjunction with our clinical trials, fees paid toindependent researchers, costs of qualifying contract manufacturers, services expenses incurred in developing and testing products and product candidates,salaries and related expenses for personnel, including stock-based compensation expense, costs of materials, depreciation, rent, utilities and other facilitiescosts. In addition, research and development expenses include the cost to support current development efforts as well as costs of product supply receivedfrom suppliers when such receipt by us is prior to regulatory approval of the supplier. We expense research and development costs as incurred.Gain (Loss) on Change in Fair Value of Derivative Liabilities. Gain (loss) on change in fair value of derivative liabilities is comprised of: (i) thechange in fair value of the warrant derivative liability, (ii) the change in fair value of the derivative liability related to the change in control provisionassociated with the December 2012 financing with BioPharma Secured Debt Fund II Holdings Cayman LP, or BioPharma, (iii) the change in fair value of thederivative liabilities related to the change in control provisions associated with the May 2014 and November 2015 exchangeable senior notes, and (iv) thechange in fair value of the derivative liability related to the preferred stock purchase option.Interest and Other (Expense) Income, Net. Interest expense consists of interest incurred under lease obligations, interest incurred under our December2012 financing arrangement with BioPharma, and interest incurred under our 3.5% exchangeable notes. Interest expense under our BioPharma financingarrangement is calculated based on an estimated repayment schedule. Interest expense under our exchangeable notes includes the amortization of theconversion option related to our exchangeable debt, the amortization of the related debt discounts and debt obligation coupon interest. Interest incomeconsists of interest earned on our cash and cash equivalents. Other (expense) income, net, consists primarily of foreign exchange losses and gains.Critical Accounting Policies and Significant Judgments and EstimatesOur discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements and notes, whichhave been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requiresus to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses. On an ongoing basis, we evaluate ourestimates and judgments, including those related to derivative financial liabilities. We base our estimates on historical experience and on various otherassumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values ofassets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.A summary of our significant accounting policies is contained in Note 2 to our consolidated financial statements included elsewhere in this Annual Reporton Form 10-K. We believe the following critical accounting policies affect our more significant judgments and estimates used in the preparation of ourconsolidated financial statements.Revenue Recognition—We sell Vascepa principally to a limited number of Distributors, that in turn resell Vascepa to retail pharmacies thatsubsequently resell it to patients and healthcare providers. In accordance with 84Table of ContentsGAAP, our revenue recognition policy requires that: (i) there is persuasive evidence that an arrangement exists between us and the Distributor, (ii) deliveryhas occurred, (iii) collectability is reasonably assured and (iv) the price is fixed or determinable.We began recognizing revenue from the sale of Vascepa following our commercial launch in the United States in January 2013. Prior to 2013, werecognized no revenue from Vascepa sales. We sell Vascepa to Distributors. In accordance with GAAP, during 2013, before we had the ability to reliablyestimate returns of Vascepa from our Distributors, revenue was recognized based on the resale of Vascepa for the purposes of filling patient prescriptions, andnot based on our sales to such Distributors. In 2014, we concluded that we had developed sufficient history such that we can reliably estimate returns and as aresult, began to recognize revenue based on sales to our Distributors. Consequently, we recognized net product revenues of $129.0 million and $81.0 millionbased on sales to Distributors during the years ended December 31, 2016 and 2015, respectively.We have written contracts with our Distributors, and delivery occurs when a Distributor receives Vascepa. We evaluate the creditworthiness of each ofour Distributors to determine whether revenues can be recognized upon delivery, subject to satisfaction of the other requirements, or whether recognition isrequired to be delayed until receipt of payment. In order to conclude that the price is fixed or determinable, we must be able to (i) calculate our gross productrevenues from the sales to Distributors and (ii) reasonably estimate our net product revenues. We calculate gross product revenues based on the wholesaleacquisition cost that we charge our Distributors for Vascepa. We estimate our net product revenues by deducting from our gross product revenues (a) tradeallowances, such as invoice discounts for prompt payment and distributor fees, (b) estimated government and private payor rebates, chargebacks anddiscounts, such as Medicaid reimbursements, (c) reserves for expected product returns and (d) estimated costs of incentives offered to certain indirectcustomers, including patients. The gross to net deductions are estimated based on available actual information, historical data, known trends, and levels ofinventory in the distribution channel. We rely on resale data provided by our Distributors as well as prescription data provided by Symphony HealthSolutions and IMS Health in estimating the level of inventory held in the distribution channel. A hypothetical 5% change in estimated aggregate bottles ofchannel inventory would result in a change of less than 1% in net product revenues reported during each of the three and twelve months ended December 31,2016 and 2015.When evaluating multiple-element arrangements, we identify the deliverables included within the agreement and evaluate which deliverablesrepresent separate units of accounting based on whether the delivered element has stand-alone value to the collaborator or if the arrangement includes ageneral right of return for delivered items. We may receive up-front, non-refundable payments when licensing our intellectual property in conjunction withresearch and development agreements. In determining the units of accounting, we evaluate whether the license has stand-alone value from the undeliveredelements to the collaborative partner based on the consideration of the relevant facts and circumstances for each arrangement. Factors considered in thisdetermination include the stage of development of the license delivered, research and development capabilities of the partner and the ability of partners todevelop and commercialize Vascepa independently.When we believe a license to our intellectual property does not have stand-alone value from the other deliverables to be provided in the arrangement,we generally recognize revenue attributable to the license over the contractual or estimated performance period. Any unrecognized portion of license revenueis classified within deferred revenue in the accompanying consolidated balance sheets. When we believe a license to our intellectual property has stand-alonevalue, we recognize revenue attributed to the license upon delivery. The periods over which revenue is recognized is subject to estimates and may changeover the course of the agreement. Such a change could have a material impact on the amount of revenue we record in future periods.Derivative Financial Liabilities—Derivative financial liabilities are initially recorded at fair value. They are subsequently held at fair value, with gainsand losses arising for changes in fair value recognized in the statement of operations. The fair value of derivative financial liabilities is determined usingvarious valuation techniques. We use our judgment to select a variety of methods and make assumptions that are mainly based on market conditions 85Table of Contentsexisting at each balance sheet date, which include our projections for future estimated revenues, management estimates of the probability of a change incontrol occurring, and the terms of debt issues of similar companies. Fluctuations in the assumptions used in the valuation model would result in adjustmentsto the fair value of the derivative liabilities reflected on our balance sheet and, therefore, our statement of operations. If we issue shares to discharge theliability, the derivative financial liability is derecognized and common stock and additional paid-in capital are recognized on the issuance of those shares.For options and warrants treated as derivative financial liabilities, at settlement date the carrying value of the options and warrants are transferred to equity.The cash proceeds received from shareholders for additional shares are recorded in common stock and additional paid-in capital. We have recorded financialderivatives related to certain outstanding warrants (extinguished during the first quarter of 2015), the change in control provision associated with ourDecember 2012 royalty-bearing debt financing, the change in control provisions associated with our May 2014 and November 2015 exchangeable seniornotes (both derecognized upon exchange of the debt hosts into equity during the third quarter of 2016), and a preferred stock purchase option (subsequentlyreclassified to permanent equity).Inventory—We capitalize purchases of saleable inventory of Vascepa from suppliers that have been qualified by the FDA. The API purchased forVascepa was sourced from three API suppliers in 2016 and 2015 and from two API suppliers in 2014. If we add a new API supplier, all Vascepa API purchasedfrom such supplier is included as a component of research and development expense until the new API supplier is approved. Upon sNDA approval of eachadditional supplier, we capitalize subsequent Vascepa API purchases from such supplier as inventory. In April 2016, we adopted Accounting StandardsUpdate (“ASU”) No. 2015-11, Inventory (Topic 330)—Simplifying the Measurement of Inventory, and as such, began to state inventories at the lower of costor net realizable market value (previously, we stated inventories at the lower of cost or market value). Cost is determined based on actual cost using theaverage cost method. An allowance is established when management determines that certain inventories may not be saleable. If inventory cost exceedsexpected net realizable value due to obsolescence, damage, quantities in excess of expected demand, changes in price levels or other causes, then we willreduce the carrying value of such inventory to net realizable value and recognize the difference as a component of cost of goods sold in the period in which itoccurs. We expense inventory identified for use as marketing samples when they are packaged. The average cost reflects the actual purchase price of VascepaAPI. Additionally, the determination of the classification of our inventory requires the use of estimates in order to determine the portion of inventoriesanticipated to be utilized within twelve months of the balance sheet date.Income Taxes—Deferred tax assets and liabilities are recognized for the future tax consequences of differences between the carrying amounts and taxbases of assets and liabilities and operating loss carryforwards and other attributes using enacted rates expected to be in effect when those differences reverse.Valuation allowances are provided against deferred tax assets that are not more likely than not to be realized.We provide reserves for potential payments of tax to various tax authorities or do not recognize tax benefits related to uncertain tax positions and otherissues. Tax benefits for uncertain tax positions are based on a determination of whether a tax benefit taken by us in our tax filings or positions is more likelythan not to be realized, assuming that the matter in question will be decided based on its technical merits. Our policy is to record interest and penalties in theprovision for income taxes.We assess our ability to realize deferred tax assets at each reporting period. The realization of deferred tax assets depends on generating future taxableincome during the periods in which the tax benefits are deductible or creditable. We have been historically profitable in the United States. When making ourassessment about the realization of our U.S. deferred tax assets as of December 31, 2016, we considered all available evidence, placing particular weight onevidence that could be objectively verified. The evidence considered included the (i) historical profitability of our U.S. operations, (ii) sources of futuretaxable income, giving weight to sources according to the extent to which they can be objectively verified and (iii) the risks to our business related to thecommercialization and development of Vascepa. Based on our assessment, we concluded that the net U.S. deferred tax assets are more likely than not to berealizable as of December 31, 2016. The majority of our deferred tax assets are held outside of the United States, for which we have established a fullvaluation 86Table of Contentsallowance. Changes in historical earnings performance and future earnings projections, among other factors, may cause us to adjust our valuation allowanceon deferred tax assets, which would impact our income tax expense in the period in which we determine that these factors have changed. In the eventsufficient taxable income is not generated in future periods, additional valuation allowances could be required relating to these U.S. deferred tax assets.In April 2016, we adopted ASU No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based PaymentAccounting, which changes the accounting for certain aspects of share-based payments to employees. Refer to recent accounting pronouncements below foradditional details on the impact of this recently adopted accounting guidance.Recent Accounting PronouncementsFrom time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board, or FASB, and are early adopted by us oradopted as of the specified effective date.In January 2016, we adopted ASU No. 2015-03, Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt IssuanceCosts, which provides guidance on simplifying the presentation of debt issuance costs on the balance sheet. To simplify presentation of debt issuance costs,the amendments in ASU No. 2015-03 require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a directdeduction from the carrying amount of that debt liability, consistent with the treatment of debt discounts. The recognition and measurement guidance fordebt issuance costs are not affected by the amendments in this update. In accordance with ASU No. 2015-03, we applied the new guidance on a retrospectivebasis, wherein the consolidated balance sheet of each individual period presented was adjusted to reflect the period-specific effects of applying the newguidance. See Note 8—Debt.In April 2016, we adopted ASU No. 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory, which simplifies the subsequentmeasurement of inventories by replacing the lower of cost or market test with a lower of cost or net realizable value test. When evidence exists that the netrealizable value of inventory is less than its cost (due to damage, physical deterioration, obsolescence, changes in price levels or other causes), we willrecognize the difference as a component of cost of goods sold in the period in which it occurs. In accordance with ASU No. 2015-11, we applied the newguidance on a prospective basis with no impact on the carrying amount of inventory.Also in April 2016, we adopted ASU No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-BasedPayment Accounting, which changes the accounting for certain aspects of share-based payments to employees. One aspect of the standard requires that excesstax benefits and deficiencies that arise upon vesting or exercise of share-based payments be recognized as an income tax benefit and expense in the incomestatement. Previously, such amounts were recognized as an increase and decrease in additional paid-in capital. This aspect of the standard was adoptedprospectively, and accordingly, the provision for income taxes for the year ended December 31, 2016 includes $0.4 million of excess tax deficiencies arisingfrom share-based payments. Additionally, the new standard requires that historical excess tax benefits that were not previously recognized because the relatedtax deduction had not reduced current taxes payable should be recognized on a modified retrospective basis as a cumulative-effect adjustment to retainedearnings as of the beginning of the annual period of adoption. Consequently, we recognized deferred tax assets of approximately $1.6 million relating toexcess tax benefits on stock-based compensation outstanding as of December 31, 2015, with a corresponding cumulative-effect adjustment to accumulateddeficit. The new standard also amends the presentation of employee share-based payment-related items in the statement of cash flows by requiring that:(i) excess income tax benefits and deficiencies be classified in cash flows from operating activities, and (ii) cash paid to taxing authorities arising from thewithholding of shares from employees be classified as cash flows from financing activities. We adopted the aspects of the standard affecting cash flowpresentation retrospectively and, accordingly, reclassified $0.7 million of excess tax benefit and $2.3 million of excess tax provision from cash flowsprovided by financing activities to cash flows used in operating activities in the consolidated statement of 87Table of Contentscash flows as of December 31, 2015 and 2014, respectively, to conform to the current year presentation. The presentation requirement for cash flows related totaxes paid for withheld shares had no impact to any of the periods presented in the consolidated statement of cash flows since such payments havehistorically been presented as a financing activity.In December 2016, we adopted ASU No. 2014-15, Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure ofUncertainties about an Entity’s Ability to Continue as a Going Concern. ASU No. 2014-15 requires management to assess an entity’s ability to continue as agoing concern by incorporating and expanding upon certain principles that are currently in U.S. auditing standards. Specifically, the ASU (i) provides adefinition of the term substantial doubt, (ii) requires an evaluation every reporting period including interim periods, (iii) provides principles for consideringthe mitigating effect of management’s plans, (iv) requires certain disclosures when substantial doubt is alleviated as a result of consideration ofmanagement’s plans, (v) requires an express statement and other disclosures when substantial doubt is not alleviated and (vi) requires an assessment for aperiod of one year after the date that the financial statements are issued (or available to be issued). We believe that our cash and cash equivalents will besufficient to fund our projected operations through the results of the REDUCE-IT study, which we anticipate will be available mid-2018.We also considered the following recent accounting pronouncements which were not yet adopted as of December 31, 2016:In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which will replace numerous requirements inU.S. GAAP, including industry-specific requirements. This guidance provides a five step model to be applied to all contracts with customers, with anunderlying principle that an entity will recognize revenue to depict the transfer of goods or services to customers at an amount that the entity expects to beentitled to in exchange for those goods or services. ASU No. 2014-09 requires extensive quantitative and qualitative disclosures covering the nature, amount,timing and uncertainty of revenue and cash flows arising from customer contracts, including disclosures on significant judgments made when applying theguidance. This guidance is effective for annual reporting periods beginning after December 15, 2017 and interim periods therein. Early adoption is permittedfor reporting periods and interim periods therein, beginning after December 15, 2016. An entity can elect to apply the guidance under one of the followingtwo methods: (i) retrospectively to each prior reporting period presented, referred to as the full retrospective method, or (ii) retrospectively with thecumulative effect of initially applying the standard recognized at the date of initial application in retained earnings, referred to as the modified retrospectivemethod.We have substantially completed an initial impact assessment of the potential changes from adopting ASU No. 2014-09. The impact assessmentconsisted of a review of a representative sample of contracts, discussions with key stakeholders, and a cataloging of potential impacts on our financialstatements, accounting policies, financial control, and operations. We anticipate that the adoption of ASU No. 2014-09 will not have a material impact onproduct revenue from distributors and may have an impact on contract revenues generated by our license agreements: (i)Changes in the model for distinct licenses of functional intellectual property which may result in a timing difference of revenue recognition.Whereas revenue from these arrangements was previously recognized over a period of time pursuant to the multiple element arrangementguidance, revenue from these arrangements may now be recognized at point in time under the new guidance. (ii)Assessments of milestone payments, which are linked to events that are in our control, will result in variable consideration that may berecognized at an earlier point in time under the new guidance, when it is probable that the milestone will be achieved without a significant futurereversal of cumulative revenue expected.We have not yet completed our final review of the impact of this guidance; however, we anticipate applying the modified retrospective method whenimplementing this guidance. We plan to adopt the new standard 88Table of Contentseffective January 1, 2018. We continue to monitor additional changes, modifications, clarifications or interpretations being undertaken by the FASB, whichmay impact our current conclusions.In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of FinancialAssets and Financial Liabilities. The new guidance is intended to improve the recognition and measurement of financial instruments by requiring separatepresentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables) withinthe balance sheet or the accompanying notes to the financial statements, eliminating the requirement for public business entities to disclose the method(s)and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost within thebalance sheet, requiring public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes,requiring equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to bemeasured at fair value with changes in fair value recognized in net income, and requiring a reporting organization to present separately in othercomprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk (alsoreferred to as “own credit”) when the organization has elected to measure the liability at fair value in accordance with the fair value option for financialinstruments, among others. The new guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscalyears. The new guidance permits early adoption of the own credit provision. We are currently evaluating the accounting, transition and disclosurerequirements of the standard and cannot currently estimate the financial statement impact of adoption.We believe that the impact of other recently issued but not yet adopted accounting pronouncements will not have a material impact on consolidatedfinancial position, results of operations, and cash flows, or do not apply to our operations.Effects of InflationWe believe the impact of inflation on operations has been minimal during the past three years.Results of OperationsComparison of Fiscal Years Ended December 31, 2016 and December 31, 2015Product Revenue, net. We recorded product revenue of $129.0 million and $81.0 million during the years ended December 31, 2016 and 2015,respectively, an increase of $48.0 million, or 59%. This increase in revenue was driven primarily by an increase in estimated normalized total Vascepaprescriptions. Based on data provided by Symphony Health Solutions and IMS Health, estimated normalized total Vascepa prescriptions increased byapproximately 339,000 and 378,000, respectively, over the year ended December 31, 2015, representing growth of 53% and 56%, respectively. During 2016,predominantly in the second quarter, wholesaler inventory levels increased based on estimated days of inventory on hand. In addition, regional stocking ofVascepa expanded at certain retail pharmacies, likely due to higher volume sales of Vascepa. We estimate that these changes in channel inventory increasednet product revenue by approximately $3.0 million to $6.0 million during 2016, compared to a $0.4 million to $0.7 million decrease in net product revenuedue to net inventory level changes during 2015. We believe that changes in channel inventory at these independent wholesalers and retail pharmacies arecommon and impacted by numerous factors, including holiday timing and recent order trends. We also believe, based on information available to us, thatchannel inventory levels at the end of both 2015 and 2016 are within ordinary ranges.All of our product revenue in the years ended December 31, 2016 and 2015 was derived from product sales of Vascepa, net of allowances, discounts,incentives, rebates, chargebacks and returns. Included in 2016 net product revenue are sales of 0.5-gram size Vascepa capsules, which were introduced inOctober 2016, for the 89Table of Contentssubset of patients who prefer a smaller capsule. Sales of Vascepa 0.5-gram size capsules have not been significant to date. The FDA-approved dosing forVascepa continues to be 4 grams per day and we expect that the majority of patients taking Vascepa will continue to be prescribed the 1-gram size Vascepacapsules. We also expect that the majority of new patients will be prescribed the 1-gram size Vascepa capsule. Timing of shipments to wholesalers, as used forrevenue recognition, and timing of prescriptions as estimated by third-party sources such as Symphony Health Solutions and IMS Health may differ fromperiod to period.During the years ended December 31, 2016 and 2015, our net product revenue included an adjustment for co-pay mitigation rebates provided by us tocommercially insured patients. Such rebates are intended to offset the differential for patients of Vascepa not covered by commercial insurers at the time oflaunch on Tier 2 for formulary purposes, resulting in higher co-pay amounts for such patients. Our cost for these co-payment mitigation rebates during theyears ended December 31, 2016 and 2015 was up to $70 per prescription filled. Since launch, certain third-party payors have added Vascepa to their Tier 2coverage, which results in lower co-payments for patients covered by these third-party payors. In connection with such Tier 2 coverage, we have agreed topay customary rebates to these third-party payors on the resale of Vascepa to patients covered by these third-party payors.As is typical for the pharmaceutical industry, the majority of Vascepa sales are to major commercial wholesalers which then resell Vascepa to retailpharmacies.Licensing Revenue. Licensing revenue during the years ended December 31, 2016 and 2015 was $1.1 million and $0.8 million, respectively, anincrease of $0.4 million, or 46%. Licensing revenue relates to the amortization of a $15.0 million up-front payment received in February 2015 and a$1.0 million milestone payment achieved in March 2016, both associated with a Vascepa licensing agreement for the China Territory. The up-front andmilestone payments are being recognized over the estimated period in which we are required to provide regulatory and development support and clinical andcommercial supply under the agreement. The amount of licensing revenue recorded may be variable from period to period based on changes in estimates ofthe timing and level of support required. We do not anticipate significant revenues related to the Biologix agreement in 2017.Cost of Goods Sold. Cost of goods sold during the years ended December 31, 2016 and 2015 was $34.4 million and $27.9 million, respectively, anincrease of $6.5 million, or 23%. Cost of goods sold includes the cost of API for Vascepa on which revenue was recognized during the period, as well as theassociated costs for encapsulation, packaging, shipment, supply management, insurance and quality assurance. The cost of the API included in cost of goodssold reflects the average cost of API included in inventory. This average cost reflects the actual purchase price of Vascepa API.The API included in the calculation of the average cost of goods sold during the years ended December 31, 2016 and 2015 was sourced from three APIsuppliers. The contracted cost of supply from our initial API supplier was higher than the contracted cost from our other API suppliers. In the future, weanticipate making continued purchases from this initial supplier and to make additional lower unit cost purchases of Vascepa API from other API suppliers,with the amount of such purchases dependent on the rate of our revenue growth. The average cost may be variable from period to period depending upon thetiming and quantity of API purchased from each supplier.Our gross margin on product sales for the years ended December 31, 2016 and 2015 was 73% and 66%, respectively. This improvement was primarilydriven by lower unit cost API purchases. 90Table of ContentsSelling, General and Administrative Expense. Selling, general and administrative expense for the years ended December 31, 2016 and 2015 was$111.4 million and $101.0 million, respectively, an increase of $10.4 million, or 10%. Selling, general and administrative expenses for the years endedDecember 31, 2016 and 2015 are summarized in the table below: Year EndedDecember 31, In thousands 2016 2015 Selling, general and administrative expense (1) $82,042 $82,474 Co-promotion fees (2) 17,969 7,967 Non-cash stock based compensation expense (3) 11,361 10,609 Non-cash warrant related compensation income — (9) Total selling, general and administrative expense $111,372 $101,041 (1)Selling, general and administrative expense, excluding co-promotion fees and non-cash compensation charges for stock compensation and warrants,for the years ended December 31, 2016 and 2015 was $82.0 million and $82.5 million, respectively, a decrease of $0.4 million, or 1%. This slightdecrease is due primarily to an increase in prior-year sales and marketing costs in support of expanded Vascepa promotion following the favorablefederal court declaration on August 7, 2015 and related settlement on March 8, 2016 allowing communication of truthful and non-misleadingANCHOR clinical trial and related data to be communicated to healthcare professionals, more than offset by lower legal costs resulting from the same.(2)Co-promotion fees payable to Kowa Pharmaceuticals America, Inc. were $18.0 million and $8.0 million in the years ended December 31, 2016 and2015, respectively, an increase of $10.0 million, or 126%. The increase is due primarily to an increase in gross margin on product sales for the yearended December 31, 2016 compared to the same period in 2015, coupled with an increase in the percentage of aggregate Vascepa gross margin earnedby Kowa Pharmaceuticals America, Inc. from 15% in 2015 to 19% in 2016.(3)Stock-based compensation expense for the years ended December 31, 2016 and 2015 was $11.4 million and $10.6 million, respectively, an increase of$0.8 million, or 7%, primarily due to an increase in new stock option and restricted stock awards granted to attract and retain qualified employees.We anticipate that selling, general and administrative expenses, excluding non-cash costs, will increase by less than 10% in 2017 compared with 2016,with the exception of commercial spending for anticipated expansion following successful REDUCE-IT results and increased co-promotion fees anticipatedto be paid to Kowa Pharmaceuticals America, Inc. associated primarily with anticipated increased revenue growth.Research and Development Expense. Research and development expense for the years ended December 31, 2016 and 2015 was $50.0 million and$51.1 million, respectively, a decrease of $1.1 million, or 2%. Research and development expenses for the years ended December 31, 2016 and 2015 aresummarized in the table below: Year EndedDecember 31, In thousands 2016 2015 REDUCE-IT study (1) $36,989 $34,706 Regulatory filing fees and expenses (2) 1,735 2,162 Internal staffing, overhead and other (3) 8,999 10,914 Research and development expense, excluding non-cash expense 47,723 47,782 Non-cash stock-based compensation (4) 2,252 3,280 Total research and development expense $49,975 $51,062 The decrease in research and development expenses for the year ended December 31, 2016, as compared to the prior year period, is primarily due to adecrease in overhead costs and non-cash stock-based compensation partially offset by quarterly variability in costs related to the REDUCE-IT study. 91Table of Contents(1)In December 2011, we announced commencement of patient dosing in our cardiovascular outcomes study of Vascepa, titled REDUCE-IT, which isdesigned to evaluate the efficacy of Vascepa, including its impact on triglyceride lowering and its other clinical effects, in reducing major adversecardiovascular events compared to placebo in patients who despite statin therapy have risk factors for cardiovascular disease, including elevatedtriglyceride levels. In 2016, we completed patient enrollment and randomization of 8,175 individual patients into the REDUCE-IT study, exceedingthe 8,000 patients targeted for the trial. The study duration is dependent on the rate of clinical events in the study, which rate may be affected by theepidemiology of the patients enrolled in the study and the length of time that the enrolled patients are followed. We manage the study through acontract research organization (CRO) through which all costs for this outcomes study are incurred with the exception of costs for clinical trial material(CTM) and costs for internal management. Our internal personnel are responsible for managing multiple projects and their costs are not specificallyallocated to REDUCE-IT or any other individual project. For the years ended December 31, 2016 and 2015, we incurred expenses through our CRO inconnection with this trial of approximately $28.8 million and $28.5 million, respectively. Inclusive of CTM costs, the combined CRO and CTM costsduring the years ended December 31, 2016 and 2015 for REDUCE-IT were approximately $37.0 million and $34.7 million, respectively. The increasein expenses in 2016 as compared to 2015 is primarily the result of timing variability for REDUCE-IT costs. We expense costs for CTM when allocatedto clinical research. The aggregate cost of this outcomes study will depend on the rate of clinical events in the study. We currently estimate that we willincur $30 million to $40 million in annual costs through study completion and the rate at which we incur such costs will vary from quarter to quarter.The study is designed to be completed after reaching 1,612 aggregate primary cardiovascular events. Based on projected event rates, we estimate theonset of the target aggregate number of cardiovascular events to be reached near the end of 2017 with study results then expected to be available andpublished in 2018. We anticipate that our costs for this outcomes study will continue to represent the most significant component of our research anddevelopment expenditures.(2)The regulatory filing fees in each of the years ended December 31, 2016 and 2015 included annual FDA fees for maintaining manufacturing sites. Suchfees primarily represent fees for qualification of new suppliers, including increasing capacity capabilities, and fees for sites used for the manufacture ofproduct used in the REDUCE-IT clinical outcomes study.(3)Internal staffing, overhead and other research and development expenses primarily relate to the costs of our personnel employed to manage research,development and regulatory affairs activities and related overhead costs including consulting and other professional fees that are not allocated tospecific projects. Also included are costs related to qualifying suppliers.(4)Non-cash stock-based compensation expense represents the costs associated with equity awards issued to internal staff supporting our research anddevelopment and regulatory functions.We anticipate that research and development expenses in 2017, excluding non-cash costs, will remain relatively consistent with 2016 levels, with themajority of such spending devoted to the ongoing REDUCE-IT trial.Gain (Loss) on Change in Fair Value of Derivative Liabilities. Gain (loss) on change in fair value of derivative liabilities for the year endedDecember 31, 2016 was a gain of $8.2 million versus a loss of $1.1 million in the prior year period. Gain (loss) on change in fair value of derivative liabilitiesfor the years ended December 31, 2016 and 2015 is comprised of (i) the change in fair value of the warrant derivative liability, (ii) the change in fair value ofthe derivative liability related to the change in control provision associated with the December 2012 BioPharma financing, (iii) the change in fair value ofthe derivative liabilities related to the change in control provisions associated with the May 2014 and November 2015 exchangeable senior notes, and(iv) the change in fair value of the derivative liability related to the preferred stock purchase option.The warrant derivative liability was related to the change in fair value of warrants issued in conjunction with the October 2009 private placement. InOctober 2009, we issued 36.1 million warrants at an exercise price of $1.50 per warrant and recorded a $48.3 million warrant derivative liability, representingthe fair value of the 92Table of Contentswarrants issued. As these warrants were classified as a derivative liability, they were revalued at each reporting period, with changes in fair value recognizedin the consolidated statement of operations. Of the 8,087,388 warrants outstanding as of December 31, 2014, 1,844,585 warrants were exercised and theremaining 6,242,803 warrants expired on February 27, 2015. As such, no warrants were outstanding as of December 31, 2015 and the derivative liability wasextinguished. The fair value of the warrant derivative liability as of December 31, 2014 was $0.1 million and we recognized a $0.1 million gain on change infair value of derivative liability for the year ended December 31, 2015. There was no such change in fair value of warrant derivative liability for the yearended December 31, 2016.Our December 2012 financing agreement with BioPharma contains a redemption feature whereby, upon a change of control, we would be required torepay $150.0 million, less any previously repaid amount, which net remaining unpaid amount as of December 31, 2016 was $125.6 million. Unless this earlyredemption feature is triggered, the remaining amount, without additional interest accumulation, is anticipated to be paid based on the royalty provisions ofthe agreement. The fair value of the derivative liability is recalculated at each reporting period using a probability-weighted model incorporatingmanagement estimates for potential change in control, and by determining the fair value of the debt with and without the change in control provisionincluded. The difference between the two fair values of the debt was determined to be the fair value of the embedded derivative. As of December 31, 2015, thefair value of the derivative was determined to be $5.5 million, and as of December 31, 2016, the fair value of the derivative was determined to be nil based oncurrent assumptions. As such, we recognized a $5.5 million gain on change in fair value of derivative liability for the year ended December 31, 2016. As ofDecember 31, 2014, the fair value of the derivative was determined to be $4.8 million, and as of December 31, 2015, the fair value of the derivative wasdetermined to be $5.5 million. As such, we recognized a $0.7 million loss on change in fair value of derivative liability for the year ended December 31,2015.Our 2014 Notes, issued in May 2014, contained a redemption feature whereby, upon occurrence of a change in control, we would have been required torepurchase the notes. The fair value of the embedded derivative was calculated using a probability-weighted model incorporating management estimates ofthe probability of a change in control occurring, and by determining the fair value of the debt with and without the change in control provision included. Thedifference between the two was determined to be the fair value of the embedded derivative. In September 2016, we exercised our optional exchange rightsupon satisfaction of specified equity conditions set forth in the 2014 Notes indenture to mandatorily exchange the 2014 Notes into ADSs (see Note 8—Debt).As such, the related derivative liability was derecognized and we recognized a $2.1 million gain on change in fair value of derivative liability for the yearended December 31, 2016. As of December 31, 2014, the fair value of the derivative was determined to be $2.6 million, and as of December 31, 2015, the fairvalue of the derivative was determined to be $2.1 million. As such, we recognized a $0.5 million gain on change in fair value of derivative liability for theyear ended December 31, 2015.Our 2015 Notes, issued in November 2015, contained the same redemption feature as the 2014 Notes and the related derivative liability was calculatedutilizing the same methodology. In September 2016, we exercised our optional exchange rights upon satisfaction of specified equity conditions consistentwith the terms of the 2015 Notes to mandatorily exchange the 2015 Notes into ADSs (see Note 8—Debt). As such, the related derivative liability wasderecognized and we recognized a $0.6 million gain on change in fair value of derivative liability for the year ended December 31, 2016. Upon issuance inNovember 2015, the fair value of the derivative was determined to be $0.5 million, and as of December 31, 2015, the fair value of the derivative wasdetermined to be $0.6 million. As such, we recognized a $0.1 million loss on change in fair value of derivative liability for the year ended December 31,2015.In connection with the closing of a private placement transaction in early March 2015, we recorded a derivative liability pursuant to a pre-existingcontractual right. This preferred stock purchase option was determined to be a derivative liability effective March 5, 2015, the date in which the privateplacement was initially subscribed. The fair value of this liability was calculated using a Black-Scholes model and was 93Table of Contentsdetermined to be $0.9 million at inception. The liability was charged to accumulated deficit as a deemed non-cash dividend and was therefore reflected as anadjustment to net loss applicable to common shareholders for earnings per common share purposes in accordance with GAAP for the year endedDecember 31, 2015. The liability was then marked to fair value through March 30, 2015, the date on which we executed a separate subscription agreementwith the investor, resulting in a charge of $0.9 million through gain (loss) on change in fair value of derivatives in the year ended December 31, 2015. Theliability of $1.8 million was then reclassified to permanent equity on March 30, 2015. There was no such change in fair value of derivative liability for theyear ended December 31, 2016.The change in fair value of the derivative liability related to the BioPharma financing agreement is largely related to our projections for futureestimated revenues, management estimates of the probability of a change in control occurring, and the terms of debt issues of similar companies. The changein fair value of the derivative liabilities related to the 2014 Notes and 2015 Notes is a result of the exchange of the related debt hosts for the year endedDecember 31, 2016 and was largely related to changes in quoted bond prices for the year ended December 31, 2015. Any changes in the assumptions used tovalue the derivative liabilities could result in a material change to the carrying value of such liabilities.Gain on Extinguishment of Debt. In November 2015, we entered into a privately negotiated subscription agreement with one of our existing investors(the “Investor”), pursuant to which the Investor agreed to purchase approximately $31.3 million in aggregate principal amount of new 3.5% November 2015Exchangeable Senior Notes due 2032 (the “2015 Notes”) for approximately $27.5 million. Concurrent with the issuance of the 2015 Notes, we entered intoseparate, privately negotiated purchase agreements with certain holders of the 3.5% January 2012 Exchangeable Senior Notes due 2032 (the “2012 Notes”)pursuant to which we purchased approximately $16.2 million in aggregate principal amount of the 2012 Notes for $15.9 million (the “2012 NotesPurchase”), which includes accrued but unpaid interest on such 2012 Notes. The 2012 Notes Purchase was funded by the issuance of the 2015 Notes.Following the closing of the 2012 Notes Purchase, we had approximately $15.1 million in aggregate principal amount of 2012 Notes outstanding. The 2012Notes Purchase was accounted for as an extinguishment of debt and we recorded a gain of $1.3 million upon extinguishment for the year ended December 31,2015, which represents the reacquisition of the conversion option at fair value and a negotiated discount on the purchase of the notes partially offset by legaland transaction advisory costs incurred. There was no such gain on extinguishment of debt for the year ended December 31, 2016.Interest Expense, net. Net interest expense for the years ended December 31, 2016 and 2015 was $18.4 million and $20.0 million, respectively, adecrease of $1.6 million, or 8%. Net interest expense for the years ended December 31, 2016 and 2015 is summarized in the table below: Year EndedDecember 31, In thousands 2016 2015 Exchangeable senior notes (1): Amortization of debt discounts $5,703 $6,362 Contractual coupon interest 4,151 5,313 Total exchangeable senior notes interest expense 9,854 11,675 Long-term debt from royalty-bearing instrument (2): Cash interest—current 6,727 6,483 Cash interest—deferred — 112 Non-cash interest 2,081 1,895 Total long-term debt from royalty-bearing instrument interest expense 8,808 8,490 Other interest expense 15 15 Total interest expense 18,677 20,180 Interest income (3) (234) (132) Total interest expense, net $18,443 $20,048 94Table of Contents (1)Cash and non-cash interest expense related to the exchangeable senior notes for the years ended December 31, 2016 and 2015 was $9.9 million and$11.7 million, respectively.(2)Cash and non-cash interest expense related to the BioPharma financing for the years ended December 31, 2016 and 2015 was $8.8 million and$8.5 million, respectively. These amounts reflect the assumption that our Vascepa revenue levels will not be high enough to support repayment toBioPharma in accordance with the repayment schedule without the optional reduction which is allowed to be elected by us if the threshold revenuelevels are not achieved. To date, our revenues have been below the contractual threshold amount each quarter such that each payment reflects thecalculated optional reduction amount as opposed to the contractual threshold payments for each quarterly period.(3)Interest income for the years ended December 31, 2016 and 2015 was $0.2 million and $0.1 million, respectively. Interest income represents incomeearned on cash balances.Other (Expense) Income, net. Other (expense) income, net, for the year ended December 31, 2016 was expense of $0.5 million versus expense of$0.2 million in the prior year period. Other (expense) income, net, in the years ended December 31, 2016 and 2015 primarily consists of gains and losses onforeign exchange transactions.(Provision for) Benefit from Income Taxes. (Provision for) benefit from income taxes for the years ended December 31, 2016 and 2015 was a provisionof $10.0 million and a benefit of $3.1 million, respectively. The current provision relates entirely to the U.S. subsidiary operations. We are profitable in theUnited States as a result of intercompany transactions between our U.S. subsidiary and our other companies. In April 2016, we adopted ASU No. 2016-09,Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which requires that excess tax benefits anddeficiencies that arise upon vesting or exercise of share-based payments be recognized as an income tax benefit and expense in the income statement.Previously, such amounts were recognized as an increase and decrease in additional paid-in capital. This aspect of the standard was adopted prospectivelyand, accordingly, the provision for income taxes for the year ended December 31, 2016 includes $0.4 million of excess tax deficiencies arising from share-based payments.Preferred Stock Purchase Option. In connection with the closing of a private placement transaction in early March 2015, we recorded a derivativeliability pursuant to a pre-existing contractual right. This preferred stock purchase option was determined to be a derivative liability effective March 5, 2015,the date in which the private placement was initially subscribed. The fair value of this liability was calculated using a Black-Scholes model and wasdetermined to be $0.9 million at inception. The liability was charged to accumulated deficit as a deemed non-cash dividend and was therefore reflected as anadjustment to net loss applicable to common shareholders for earnings per common share purposes in accordance with GAAP for the year endedDecember 31, 2015. There was no such adjustment to net loss for the year ended December 31, 2016.Preferred Stock Beneficial Conversion Features. In 2015, we issued Series A preference shares in a private placement transaction executed in twotranches that each contain a conversion feature whereby such shares are convertible into ordinary shares at a fixed rate (see Note 10—Equity). The conversionprice on the date of issuance was less than the market price of our ordinary shares on such date. We determined that these discounts represent contingentbeneficial conversion features, which were valued based on the difference between the conversion price and the market price of the ordinary shares on thedate of issuance. These features are analogous to preference dividends and were recorded as non-cash returns to preferred shareholders through accumulateddeficit, and are therefore reflected as adjustments to net loss applicable to common shareholders for earnings per common share purposes in accordance withGAAP. During the year ended December 31, 2015, we recorded an adjustment to net loss applicable to common shareholders of $31.3 million uponeffectiveness of the related resale Registration Statement on Form S-3 and $1.6 million upon shareholder approval received at the Company’s Annual GeneralMeeting of Shareholders. There was no such adjustment to net loss in the year ended December 31, 2016. 95Table of ContentsComparison of Fiscal Years Ended December 31, 2015 and December 31, 2014Product Revenue, net. We recorded product revenue of $81.0 million and $54.2 million during the years ended December 31, 2015 and 2014,respectively, an increase of $26.8 million, or 49%. This increase in revenue was driven by an increase in estimated normalized total Vascepa prescriptions ofapproximately 228,000 and 258,000 based on data provided by Symphony Health Solutions and IMS Health, respectively, representing growth of 55% and62%, respectively, over the year ended December 31, 2014. The difference in the percentage of revenue growth as compared to the percentage of prescriptiongrowth is primarily due to a change in revenue recognition methodology in 2014 as described below. The level of inventories held by our customers as ofDecember 31, 2015 was slightly lower as compared to inventories held as of December 31, 2014 based on days on hand. All of our product revenue in theyears ended December 31, 2015 and 2014 was derived from product sales of Vascepa, net of allowances, discounts, incentives, rebates, chargebacks andreturns. In accordance with GAAP, prior to 2014, product revenue was recognized based on the resale of Vascepa for the purposes of filling patientprescriptions and not based on sales to our Distributors. During the three months ended March 31, 2014, we concluded that we had developed sufficienthistory such that we can reliably estimate returns and, as a result, began to recognize product revenue based on sales to our Distributors. ThroughDecember 31, 2015, product returns of Vascepa were de minimis. Timing of shipments to wholesalers, as used for revenue recognition, and timing ofprescriptions as estimated by third-party sources such as Symphony Health Solutions and IMS Health may differ from period to period.During the years ended December 31, 2015 and 2014, our net product revenue included an adjustment for co-pay mitigation rebates provided by us tocommercially insured patients. Such rebates are intended to offset the differential for patients of Vascepa not covered by commercial insurers at the time oflaunch on Tier 2 for formulary purposes, resulting in higher co-pay amounts for such patients. Our cost for these co-payment mitigation rebates was up to $75per prescription filled prior to February 20, 2014 and up to $70 per prescription filled after February 20, 2014. Since launch, certain third-party payors haveadded Vascepa to their Tier 2 coverage, which results in lower co-payments for patients covered by these third-party payors. In connection with such Tier 2coverage, we have agreed to pay customary rebates to these third-party payors on the resale of Vascepa to patients covered by these third-party payors. As istypical for the pharmaceutical industry, the majority of Vascepa sales are to major commercial wholesalers which then resell Vascepa to retail pharmacies.Licensing Revenue. Licensing revenue during the year ended December 31, 2015 was $0.8 million. We did not record licensing revenue prior to 2015.The licensing revenue relates to the amortization of a $15.0 million up-front payment received in February 2015 associated with a Vascepa licensingagreement for the China Territory. The up-front payment is being recognized over the estimated period in which we are required to provide regulatory anddevelopment support and clinical and commercial supply, which is currently anticipated to be a period of approximately 16 years. The amount of licensingrevenue recorded may be variable from period to period based on changes in estimates of the timing and level of support required.Cost of Goods Sold. Cost of goods sold during the years ended December 31, 2015 and 2014 was $27.9 million and $20.5 million, respectively, anincrease of $7.4 million, or 36%. Cost of goods sold includes the cost of API for Vascepa on which revenue was recognized during the period, as well as theassociated costs for encapsulation, packaging, shipment, supply management, insurance and quality assurance. The cost of the API included in cost of goodssold reflects the average cost of API included in inventory. This average cost reflects the actual purchase price of Vascepa API.The API included in the calculation of the average cost of goods sold was sourced from three API suppliers for the year ended December 31, 2015 andfrom two API suppliers for the year ended December 31, 2014. The contracted cost of supply from our initial API supplier was higher than the contracted costfrom our other API suppliers. In the future, we anticipate making continued purchases from this initial supplier and to make additional lower unit costpurchases of Vascepa API from other API suppliers, with the amount of such purchases dependent on the rate of our revenue growth. 96Table of ContentsOur gross margin on product sales for the years ended December 31, 2015 and 2014 was 66% and 62%, respectively. This improvement was primarilydriven by lower unit cost API purchases. In addition, over time we expect continued lower average unit cost purchases of API. We also expect that API costswill be lower in the future due to advantages derived from the mix of our suppliers. The average cost may be variable from period to period depending uponthe timing and quantity of API purchased from each supplier.Selling, General and Administrative Expense. Selling, general and administrative expense for the years ended December 31, 2015 and 2014 was$101.0 million and $79.3 million, respectively, an increase of $21.7 million, or 27%. Selling, general and administrative expenses for the years endedDecember 31, 2015 and 2014 are summarized in the table below (in thousands): Year EndedDecember 31, 2015 2014 Selling, general and administrative expense (1) $82,474 $71,864 Co-promotion fees (2) 7,967 1,664 Non-cash stock based compensation expense (3) 10,609 6,321 Non-cash warrant related compensation income (9) (503) Total selling, general and administrative expense $101,041 $79,346 (1)Selling, general and administrative expense, excluding non-cash compensation charges for stock compensation and warrants and co-promotion fees,for the years ended December 31, 2015 and 2014 was $82.5 million and $71.9 million, respectively, an increase of $10.6 million, or 15%. The increaseis due primarily to increased sales and marketing spend in support of expanded Vascepa promotion following the federal court declaration onAugust 7, 2015 allowing communication of truthful and non-misleading ANCHOR clinical trial data to be communicated to healthcare professionals,as well as higher legal costs associated with various legal matters, which costs vary from period to period.(2)Co-promotion fees payable to Kowa Pharmaceuticals America, Inc. were $8.0 million and $1.7 million in the years ended December 31, 2015 and2014, respectively, an increase of $6.3 million, or 371%. Kowa Pharmaceuticals America, Inc. commenced its co-promotion efforts in May 2014.(3)Stock-based compensation expense for the years ended December 31, 2015 and 2014 was $10.6 million and $6.3 million, respectively, an increase of$4.3 million, or 68%, primarily due to an increase in new stock option and restricted stock awards granted to attract and retain qualified employees.We currently anticipate that prior to REDUCE-IT data, our selling, general and administrative costs in 2016 will be substantially consistent with that in2015, with the exception of non-cash costs and anticipated increases in the co-promotion fees earned by Kowa Pharmaceuticals America, Inc. based onanticipated increases in net product revenues and the terms of our co-promotion agreement with Kowa Pharmaceuticals America, Inc.Research and Development Expense. Research and development expense for the years ended December 31, 2015 and 2014 was $51.1 million and$50.3 million, respectively, an increase of $0.8 million, or 2%. Research and development expenses for the years ended December 31, 2015 and 2014 aresummarized in the table below (in thousands): Year EndedDecember 31, 2015 2014 REDUCE-IT study (1) $34,706 $37,672 Regulatory filing fees and expenses (2) 2,162 1,847 Internal staffing, overhead and other (3) 10,914 8,106 Research and development expense, excluding non-cash expense 47,782 47,625 Non-cash stock-based compensation (4) 3,280 2,701 Total research and development expense $51,062 $50,326 97Table of ContentsThe increase in research and development expenses for the year ended December 31, 2015, as compared to the prior year period, is primarily due to anincrease in internal staffing and overhead costs and non-cash stock-based compensation partially offset by quarterly variability in costs related to theREDUCE-IT study. (1)In December 2011, we announced commencement of patient dosing in our cardiovascular outcomes study of Vascepa, titled REDUCE-IT, which isdesigned to evaluate the efficacy of Vascepa in reducing major cardiovascular events in a high-risk patient population on statin therapy. The studyduration is dependent on the rate of clinical events in the study, which rate may be affected by the number of patients enrolled in the study, theepidemiology of the patients enrolled in the study, and the length of time that the enrolled patients are followed. We manage the study through a CROthrough which all costs for this outcomes study are incurred with the exception of costs for CTM and costs for internal management. Our internalpersonnel are responsible for managing multiple projects and their costs are not specifically allocated to REDUCE-IT or any other individual project.For the years ended December 31, 2015 and 2014, we incurred expenses through our CRO in connection with this trial of approximately $28.5 millionand $31.0 million, respectively. Inclusive of CTM costs, the combined CRO and CTM costs during the years ended December 31, 2015 and 2014 forREDUCE-IT were approximately $34.7 million and $37.7 million, respectively. The decrease in expenses in 2015 as compared to 2014 is primarily theresult of timing variability for REDUCE-IT costs. We expense costs for CTM when allocated to clinical research. The aggregate cost of this outcomesstudy will depend on the rate of clinical events in the study. We currently estimate we will incur $30 million to $40 million in annual costs throughstudy completion and the rate at which we incur such costs will vary from quarter to quarter. The study is designed to be completed after reaching1,612 aggregate primary cardiovascular events. Based on projected event rates, we estimate the onset of the target aggregate number of cardiovascularevents to be reached in or about 2017 with study results then expected to be available and published in 2018. We anticipate that our costs for thisoutcomes study will continue to represent the most significant component of our research and development expenditures.(2)The regulatory filing fees in each of the years ended December 31, 2015 and 2014 included annual FDA fees for maintaining manufacturing sites.(3)Internal staffing, overhead and other research and development expenses primarily relate to the costs of our personnel employed to manage research,development and regulatory affairs activities and related overhead costs including consulting and other professional fees that are not allocated tospecific projects. Also included are costs related to qualifying suppliers and legal costs.(4)Non-cash stock-based compensation expense represents the costs associated with equity awards issued to internal staff supporting our research anddevelopment and regulatory functions.Research and development costs, excluding non-cash costs, are expected to vary from quarter to quarter in 2016 due to the timing of REDUCE-ITcosts.Gain (Loss) on Change in Fair Value of Derivative Liabilities. Gain (loss) on change in fair value of derivative liabilities for the year endedDecember 31, 2015 was a loss of $1.1 million versus a gain of $13.5 million in the prior year period. Gain (loss) on change in fair value of derivativeliabilities is comprised of (i) the change in fair value of the warrant derivative liability, (ii) the change in fair value of the derivative liability related to thechange in control provision associated with the December 2012 BioPharma financing, (iii) the change in fair value of the derivative liabilities related to thechange in control provisions associated with the May 2014 and November 2015 exchangeable senior notes; and (iv) the change in fair value of the derivativeliability related to the preferred stock purchase option.The warrant derivative liability is related to the change in fair value of warrants issued in conjunction with the October 2009 private placement. InOctober 2009, we issued 36.1 million warrants at an exercise price of $1.50 per warrant and recorded a $48.3 million warrant derivative liability, representingthe fair value of the warrants issued. As these warrants have been classified as a derivative liability, they are revalued at each reporting period, with changesin fair value recognized in the statement of operations. The fair value of the 98Table of Contentswarrant derivative liability as of December 31, 2014 was $0.1 million and we recognized a $0.1 million gain on change in fair value of derivative liability forthe year ended December 31, 2015 for these warrants. The fair value of the warrant derivative liability as of December 31, 2013 was $6.9 million and werecognized a $6.3 million gain on change in fair value of derivative liability for the year ended December 31, 2014. The change in fair value of the warrantderivative liability for the year ended December 31, 2015 is due to the expiration of the warrants and the resulting extinguishment of the liability, while thechange in fair value for the year ended December 31, 2014 is due primarily to the change in the price of our common stock on the date of valuation. InOctober 2014, we and the holders of the remaining October 2009 warrants mutually agreed to extend the expiration date of such warrants from October 16,2014 to February 27, 2015. Of the 8,087,388 warrants outstanding as of December 31, 2014, 1,844,585 warrants were exercised and the remaining 6,242,803warrants expired on February 27, 2015. As such, no warrants were outstanding as of December 31, 2015.Our December 2012 financing agreement with BioPharma contains a redemption feature whereby, upon a change of control, we would be required torepay $150.0 million, less any previously repaid amount. The fair value of the derivative liability is recalculated at each reporting period using a probability-weighted model incorporating management estimates for potential change in control, and by determining the fair value of the debt with and without thechange in control provision included. The difference between the two fair values of the debt was determined to be the fair value of the embedded derivative.As of December 31, 2014, the fair value of the derivative was determined to be $4.8 million, and as of December 31, 2015, the fair value of the derivative wasdetermined to be $5.5 million. As such, we recognized a $0.7 million loss on change in fair value of derivative liability for the year ended December 31,2015. As of December 31, 2013, the fair value of the derivative was determined to be $11.1 million, and as of December 31, 2014, the fair value of thederivative was determined to be $4.8 million. As such, we recognized a $6.3 million gain on change in fair value of derivative liability for the year endedDecember 31, 2014.Our 2014 Notes, issued in May 2014, contain a redemption feature whereby, upon occurrence of a change in control, we would be required torepurchase the notes. The fair value of the embedded derivative was calculated using a probability-weighted model incorporating management estimates ofthe probability of a change in control occurring, and by determining the fair value of the debt with and without the change in control provision included. Thedifference between the two was determined to be the fair value of the embedded derivative. As of December 31, 2014, the fair value of the derivative wasdetermined to be $2.6 million, and as of December 31, 2015, the fair value of the derivative was determined to be $2.1 million. As such, we recognized a$0.5 million gain on change in fair value of derivative liability for the year ended December 31, 2015. Upon initial recording, the fair value of the derivativewas determined to be $3.5 million, and as of December 31, 2014, the fair value of the derivative was determined to be $2.6 million. As such, we recognized a$0.9 million gain on change in fair value of derivative liability for the year ended December 31, 2014.Our 2015 Notes, issued in November 2015, contain the same redemption feature as the 2014 Notes and the related derivative liability was calculatedutilizing the same methodology. Upon issuance in November 2015, the fair value of the derivative was determined to be $0.5 million, and as of December 31,2015, the fair value of the derivative was determined to be $0.6 million. As such, we recognized a $0.1 million loss on change in fair value of derivativeliability for the year ended December 31, 2015.In connection with the closing of a private placement transaction in early March 2015, we recorded a derivative liability pursuant to a pre-existingcontractual right. This preferred stock purchase option was determined to be a derivative liability effective March 5, 2015, the date in which the privateplacement was initially subscribed. The fair value of this liability was calculated using a Black-Scholes model and was determined to be $0.9 million atinception. The liability was charged to accumulated deficit as a deemed non-cash dividend and is therefore reflected as an adjustment to net loss applicableto common shareholders for earnings per common share purposes in accordance with GAAP. The liability was then marked to fair value through March 30,2015, the date on which we executed a separate subscription agreement with the investor, resulting in a charge of $0.9 million through gain (loss) on changein fair value of derivatives in the year ended December 31, 2015. The liability was reclassified to permanent equity on such date. 99Table of ContentsThe change in fair value of the derivative liability related to the BioPharma financing agreement is largely related to our projections for futureestimated revenues, management estimates of the probability of a change in control occurring, and the terms of debt issues of similar companies. The changein fair value of the derivative liabilities related to the 2014 Notes and 2015 Notes is largely related to changes in quoted bond prices. Any changes in theassumptions used to value the derivative liabilities could result in a material change to the carrying value of such liabilities.Gain on Extinguishment of Debt. On May 15, 2014, we entered into separate, privately negotiated exchange agreements with certain holders of ourexchangeable senior notes pursuant to which we exchanged $118.7 million in aggregate principal amount of existing exchangeable senior notes for$118.7 million in aggregate principal amount of new 3.5% exchangeable senior notes due 2032. The key changes in the terms of the new notes includedmoving the first put date from January 2017 to January 2019, adding an issuer conversion option whereby we can opt to convert the notes into equity shouldthe Daily VWAP (as defined in the Indenture) exceed $2.86 for a certain number of days and reducing the conversion price (see Note 8). As a result of theexchange, we assessed the value of the notes immediately prior to the exchange and immediately after the exchange and determined that the exchangeresulted in a substantial modification of the terms of the notes resulting in an extinguishment of the original notes. We recorded a gain on extinguishment ofthe original notes of $38.0 million in the year ended December 31, 2014.In November 2015, we entered into a privately negotiated subscription agreement with one of our existing investors (the “Investor”), pursuant to whichthe Investor agreed to purchase approximately $31.3 million in aggregate principal amount of new 3.5% November 2015 Exchangeable Senior Notes due2032 (the “2015 Notes”) for approximately $27.5 million. Concurrent with the issuance of the 2015 Notes, we entered into separate, privately negotiatedpurchase agreements with certain holders of the 3.5% January 2012 Exchangeable Senior Notes due 2032 (the “2012 Notes”) pursuant to which we purchasedapproximately $16.2 million in aggregate principal amount of the 2012 Notes for $15.9 million (the “2012 Notes Purchase”), which includes accrued butunpaid interest on such 2012 Notes. The 2012 Notes Purchase was funded by the issuance of the 2015 Notes. Following the closing of the 2012 NotesPurchase, we had approximately $15.1 million in aggregate principal amount of 2012 Notes outstanding. The 2012 Notes Purchase was accounted for as anextinguishment of debt and we recorded a gain of $1.3 million upon extinguishment, which represents the reacquisition of the conversion option at fair valueand a negotiated discount on the purchase of the notes partially offset by legal and transaction advisory costs incurred. 100Table of ContentsInterest Expense, net. Net interest expense for the years ended December 31, 2015 and 2014 was $20.0 million and $18.5 million, respectively, anincrease of $1.5 million, or 8%. Net interest expense for the years ended December 31, 2015 and 2014 is summarized in the table below (in thousands): Year EndedDecember 31, 2015 2014 Exchangeable senior notes (1): Amortization of debt discounts $6,362 $4,221 Contractual coupon interest 5,313 5,250 Total exchangeable senior notes interest expense 11,675 9,471 Long-term debt from royalty-bearing instrument (2): Cash interest—current 6,483 5,420 Cash interest—deferred 112 1,783 Non-cash interest 1,895 1,900 Total long-term debt interest expense 8,490 9,103 Other interest expense 15 1 Total interest expense 20,180 18,575 Interest income (3) (132) (96) Total interest expense, net $20,048 $18,479 (1)Cash and non-cash interest expense related to the exchangeable senior notes for the years ended December 31, 2015 and 2014 was $11.7 million and$9.5 million, respectively.(2)Cash and non-cash interest expense related to the BioPharma financing for the years ended December 31, 2015 and 2014 was $8.5 million and$9.1 million, respectively. These amounts reflect the assumption that our Vascepa revenue levels will not be high enough to support repayment toBioPharma in accordance with the repayment schedule without the optional reduction which is allowed to be elected by us if the threshold revenuelevels are not achieved. To date, our revenues have been below the contractual threshold amount each quarter such that each payment reflects thecalculated optional reduction amount as opposed to the contractual threshold payments for each quarterly period.(3)Interest income for the years ended December 31, 2015 and 2014 was $0.1 million in each year. Interest income represents income earned on cashbalances.Other (Expense) Income, net. Other (expense) income, net, for the years ended December 31, 2015 was expense of $0.2 million versus income of$3.7 million in the prior year period. Other (expense) income, net, in the year ended December 31, 2015 primarily consists of losses and gains on foreignexchange transactions. Other (expense) income, net in the year ended December 31, 2014 primarily consists of $4.1 million received in the second quarter of2014 with respect to settlement agreements with one of our suppliers and one of our encapsulators that provided for the reimbursement of certain amountspreviously paid by us.Benefit from Income Taxes. Benefit from income taxes for the years ended December 31, 2015 and 2014 was $3.1 million and $2.8 million,respectively. The current benefit relates entirely to the U.S. subsidiary operations. We are profitable in the United States as a result of intercompanytransactions between our U.S. subsidiary and our other companies.Preferred Stock Beneficial Conversion Features. We issued Series A preference shares in a private placement transaction executed in two tranches thateach contain a conversion feature whereby such shares are convertible into ordinary shares at a fixed rate (see Note 10). The conversion price on the date ofissuance was less than the market price of our ordinary shares. We determined that these discounts represent contingent beneficial conversion features, whichwere valued based on the difference between the conversion price and the market price of the ordinary shares on the date of issuance. These features, totaling$33.0 million, are analogous 101Table of Contentsto preference dividends and were each recorded as a non-cash return to preferred shareholders through accumulated deficit, and are therefore reflected as anadjustment to net loss applicable to common shareholders for earnings per common share purposes in accordance with GAAP. There was no such adjustmentin the year ended December 31, 2014.Liquidity and Capital ResourcesOur sources of liquidity as of December 31, 2016 include cash and cash equivalents of $98.3 million. On August 16, 2016, we completed a publicoffering of 24,265,000 American Depositary Shares, or ADSs. The underwriters purchased the ADSs from us at a price of $2.679 per ADS after commission,resulting in net proceeds to us of approximately $64.6 million, after deducting estimated offering expenses payable by us. Our projected uses of cash includecommercialization of Vascepa, the continued funding of the REDUCE-IT cardiovascular outcomes study, working capital and other general corporateactivities. Our cash flows from operating, investing and financing activities, as reflected in the consolidated statements of cash flows, are summarized in thefollowing table: Years Ended December 31, In millions 2016 2015 2014 Cash (used in) provided by: Operating activities (1) $(71.8) $(84.0) $(74.6) Investing activities — — — Financing activities (1) 63.1 71.4 2.6 Decrease in cash and cash equivalents $(8.7) $(12.6) $(72.0) (1)Due to the adoption of ASU No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based PaymentAccounting, and retrospective application of the aspects of the standard that affect cash flow presentation, $0.7 million of excess tax benefit and$2.3 million of excess tax provision have been reclassified from cash flows provided by financing activities to cash flows used in operating activitiesfor the years ended December 31, 2015 and 2014, respectively.Net cash used in operating activities during 2016 compared to 2015 decreased primarily as a result of increased collections resulting from higherrevenues and decreased legal costs following the favorable federal court declaration on August 7, 2015 and related settlement on March 8, 2016 allowingcommunication of truthful and non-misleading ANCHOR clinical trial and related data to be communicated to healthcare professionals, partially offset byreceipt in 2015 of $15.0 million in up-front proceeds from the Eddingpharm license agreement. Increased sales and marketing spend in 2016 in support ofexpanded Vascepa promotion was more than offset by higher collections from product.On December 6, 2012 we entered into a financing agreement with BioPharma. Under this agreement, we granted to BioPharma a security interest infuture receivables and all related rights to Vascepa, in exchange for $100.0 million received at the closing of the agreement which closing occurred inDecember 2012. We have agreed to repay BioPharma up to $150.0 million of future revenue and receivables. As of December 31, 2016, the net remainingamount to be repaid to BioPharma is $125.6 million. To date, our revenues have been below the contractual threshold amount such that each payment madehas reflected the calculated optional reduction amount as opposed to the contractual threshold payments for each quarterly period. For example, based on ourVascepa net product revenue for 2016 of $129.0 million, the amount repaid to BioPharma based on 2016 revenue was $12.9 million compared to themaximum contractual threshold for 2016 of $55.0 million. The maximum amount payable under the contractual threshold for the first half of 2017 is$16.8 million, after which the maximum amount payable is subject to the calculated threshold limitation based on quarterly Vascepa revenues. In accordancewith the agreement with BioPharma, quarterly differences between the calculated optional reduction amounts and the repayment schedule amounts arerescheduled for payment after 2016 and any such 102Table of Contentsdeferred payments will remain subject to continued application of the quarterly ceiling in amounts due established by the calculated threshold for royaltybased on quarterly Vascepa revenues. No additional interest expense or liability is incurred as a result of such deferred repayments. The agreement does notexpire until $150.0 million in aggregate has been repaid. We can prepay an amount equal to $150.0 million less any previously repaid amount. We currentlyestimate that Vascepa revenue levels will not be high enough in each quarter to support repayment to BioPharma in accordance with threshold amounts inthe repayment schedule and that such payments will remain subject to the continued application of the calculated threshold for royalty based on quarterlyVascepa revenues.On January 9, 2012, through our wholly-owned subsidiary Corsicanto Designated Activity Company (formerly Corsicanto Limited), or Corsicanto, aprivate limited company incorporated under the laws of Ireland, we completed a private placement of $150.0 million in aggregate principal amount of 3.5%exchangeable senior notes due 2032, or the 2012 Notes. The proceeds we received from the January 2012 debt offering were approximately $144.3 million,net of fees and transaction costs. On May 20, 2014, we entered into separate, privately negotiated exchange agreements with certain holders of the 2012Notes pursuant to which Corsicanto exchanged $118.7 million in aggregate principal amount of the 2012 Notes for $118.7 million in aggregate principalamount of new 3.5% May 2014 Exchangeable Senior Notes due 2032, or the 2014 Notes. In November 2015, $16.2 million of the 2012 Notes wasextinguished, following which $15.1 million in aggregate principal amount of the 2012 Notes remained outstanding with terms unchanged. Also inNovember 2015, we entered into a privately negotiated subscription agreement with one of our existing investors or the Investor, pursuant to which theInvestor agreed to purchase approximately $31.3 million in aggregate principal amount of new 3.5% November 2015 Exchangeable Senior Notes due 2032,or the 2015 Notes, for approximately $27.5 million. In September 2016, we exercised our optional exchange rights upon satisfaction of specified equityconditions set forth in the 2014 Notes and 2015 Notes to mandatorily exchange the entirety of the 2014 Notes and 2015 Notes into ADSs, such that the onlyexchangeable senior notes that remained outstanding as of December 31, 2016 are the 2012 Notes (see Note 8—Debt).The 2012 Notes were issued pursuant to an indenture dated as of January 9, 2012, by and among Corsicanto, us as guarantor, and Wells Fargo Bank,National Association, as trustee. The notes are the senior unsecured obligations of Corsicanto and are guaranteed by us. The 2012 Notes bear interest at a rateof 3.5% per annum, payable semi-annually in arrears on January 15 and July 15 of each year, beginning on July 15, 2012. The notes mature on January 15,2032, unless earlier repurchased, redeemed or exchanged. On or after January 19, 2017, we may elect to redeem for cash all or a portion of the notes for theprincipal amount of the notes, plus accrued and unpaid interest. On each of January 19, 2017, January 19, 2022 and January 19, 2027, the holders of the notesmay require that we repurchase in cash the principal amount of the notes plus accrued and unpaid interest. At any time prior to January 15, 2032, upon certaincircumstances, which circumstances include our issuing a notice of redemption to the note holders, the price of our shares trading above 130% of theexchange price, or certain other events defined in the note agreement, the holders of the notes may elect to convert the notes. The exchange rate forconversion is 113.4752 ADSs per $1,000 principal amount of the notes (equivalent to an initial exchange price of approximately $8.8125 per ADS), subjectto adjustment in certain circumstances, including adjustment if we pay cash dividends. Upon exchange, the notes may be settled, at our election, subject tocertain conditions, in cash, ADSs or a combination of cash and ADSs. As a result, the carrying value of the 2012 Notes of $15.1 million is classified as acurrent liability as of December 31, 2016.In January 2017, approximately $15.0 million of the 2012 Notes were put to us, such that $0.1 million of the 2012 Notes currently remainsoutstanding. We have initiated the process to redeem the $0.1 million of outstanding principal amount of 2012 Notes, which we expect will be completed inthe first quarter of 2017.Also in January 2017, we, through our wholly-owned subsidiary Corsicanto II Designated Activity Company, or Corsicanto II, a private designatedactivity company incorporated under the laws of Ireland, entered into separate, privately negotiated purchase agreements with certain investors pursuant towhich we issued and sold $30.0 million in aggregate principal amount of 3.5% exchangeable senior notes due 2047, or the 2017 Notes. The net proceeds we 103Table of Contentsreceived from the January 2017 offering were approximately $28.9 million, after deducting placement agent fees and estimated offering expenses, a portionof which was used to replenish approximately $15.0 million of cash on hand that we used to purchase substantially all of the 2012 Notes put to us in January2017.The 2017 Notes were issued pursuant to an indenture dated as of January 25, 2017, by and among Corsicanto II, us as guarantor, and Wilmington Trust,National Association, as trustee. The 2017 Notes are the senior unsecured obligations of the Issuer and are guaranteed by us. The 2017 Notes bear interest at arate of 3.5% per annum from, and including, January 25, 2017, payable semi-annually in arrears on January 15 and July 15 of each year, beginning onJuly 15, 2017. The 2017 Notes will mature on January 15, 2047, unless earlier repurchased, redeemed or exchanged. On or after January 19, 2021, we mayredeem for cash all or a portion of the 2017 Notes at a redemption price of 100% of the aggregate principal amount of the 2017 Notes to be redeemed, plusaccrued and unpaid interest. On January 19, 2022, holders of the 2017 Notes may require that we repurchase in cash all or any portion of the 2017 Notes at aprice equal to 100% of the aggregate principal amount of the 2017 Notes to be repurchased, plus accrued and unpaid interest. At any time prior to January 15,2047, the holders may exchange their 2017 Notes for ADSs at their option, and we may mandatorily exchange the 2017 Notes if the price of our shares tradesabove 130% of the exchange price then in effect for 20 VWAP trading days in any 30 consecutive VWAP trading day period (as defined in the indenture).The initial exchange rate for such conversion is 257.2016 ADSs per $1,000 principal amount of the 2017 Notes (equivalent to an initial exchange price ofapproximately $3.89 per ADS), subject to adjustment upon the occurrence of certain events, including the payment of cash dividends. Upon exchange, the2017 Notes are to be settled in ADSs.As of December 31, 2016, we had cash and cash equivalents of $98.3 million, a decrease of $8.7 million from December 31, 2015. The decrease isprimarily due to net cash used in operating activities in support of the commercialization of Vascepa and funding of REDUCE-IT offset by proceeds fromfinancing activities and accounts receivable collections. Included in our cash balance as of December 31, 2016 are net proceeds of $64.6 million we receivedupon completion of a public offering of 24,265,000 ADSs in August 2016. In January 2017, we, through our wholly-owned subsidiary Corsicanto II, issuedand sold $30.0 million in aggregate principal amount of 2017 Notes, resulting in net proceeds of approximately $28.9 million, a portion of which was used toreplenish approximately $15.0 million of cash on hand that we used to purchase substantially all of the 2012 Notes put to us in January 2017. We haveincurred annual operating losses since our inception and, as a result, we had an accumulated deficit of $1.2 billion as of December 31, 2016. We believe thatour net cash flow from operations in 2017, excluding interest, royalties and R&D costs, the majority of which are associated with REDUCE-IT, will bepositive for 2017. We anticipate that quarterly net cash outflows in future periods will be variable as a result of the timing of certain items, including ourintention in early 2017 to increase purchases of API. In addition, certain customers have indicated their intent to negotiate extended payment terms with us,which would result in slower collections of receivables. We believe that our cash and cash equivalents will be sufficient to fund our projected operationsthrough the results of the REDUCE-IT study, which we anticipate will be available mid-2018. Depending on the level of cash generated from operations,additional capital may be required to sustain operations, fund debt obligations or expand promotion of Vascepa as contemplated based on anticipatedsuccessful results of the REDUCE-IT study. 104Table of ContentsContractual ObligationsThe following table summarizes our contractual obligations as of December 31, 2016 and the effects such obligations are expected to have on ourliquidity and cash flows in future periods:Payments Due by Period In millions Total 2017 2018to 2019 2020to 2021 After 2021 Contractual Obligations: Purchase obligations (1) $44.6 $11.8 $22.1 $10.7 $— Operating lease obligations (2) 0.6 0.5 0.1 — — Interest payment obligations—exchangeable debt (3) 5.5 0.8 2.1 2.1 0.5 Exchangeable debt repurchase (4) 15.1 15.1 — — — Total contractual cash obligations $65.8 $28.2 $24.3 $12.8 $0.5 (1)We have Vascepa API supply agreements with three independent companies from which we purchase qualified API supply: Nisshin, Chemport andFinorga SAS, or Novasep. We also have encapsulation agreements with three FDA-approved commercial API encapsulators for Vascepa manufacturing:Patheon, Inc. (formerly Banner Pharmacaps), Catalent Pharma Solutions, and Capsugel Plöermel SAS, LLC, or Capsugel. Our agreements withChemport, Novasep, and Capsugel contain minimum annual purchase levels to enable us to maintain certain supply exclusivity and also contain aprovision that any shortfall in the minimum purchase commitments is payable in cash. Each supplier is required to meet certain performanceobligations and the agreements may be terminated by us in the event of non-performance.(2)Represents operating lease costs, primarily consisting of leases for facilities in Dublin, Ireland and Bedminster, NJ, net of sublease rental income.(3)Represents scheduled interest payments due under the terms of the 2012 Notes and 2017 Notes, assuming that they have not been exchanged for ADSsprior to January 19, 2017, the first put date in the 2012 Notes, and January 19, 2022, the put date in the 2017 Notes. The above table does not reflectthe repayment of the notes, unless otherwise described, as they may be exchanged for ADSs prior to maturity.(4)Represents repurchase of approximately $15.0 million in aggregate principal amount of 2012 Notes put to us by holders on January 19, 2017, and$0.1 million in aggregate principal amount of 2012 Notes to be redeemed by us, expected to be in the first quarter of 2017.On December 6, 2012, we entered into an agreement with BioPharma Secured Debt Fund II Holdings Cayman LP, or BioPharma. Under this agreement,we granted to BioPharma a security interest in future receivables associated with the Vascepa patent rights, in exchange for $100.0 million received at theclosing of the agreement which occurred in December 2012. We agreed to repay BioPharma up to $150.0 million of future revenue and receivables. As ofDecember 31, 2016, the net remaining amount to be repaid to BioPharma is $125.6 million. To date, each payment made has reflected the calculated optionalreduction amount as opposed to the contractual threshold payments for each quarterly period. For example, based on our Vascepa net product revenue for2016 of $129.0 million, the amount repaid to BioPharma based on 2016 revenue was $12.9 million compared to the maximum contractual threshold for 2016of $55.0 million. The maximum amount payable under the contractual threshold for the first half of 2017 is $16.8 million, after which the maximum amountpayable is subject to the calculated threshold limitation based on quarterly Vascepa revenues. In accordance with the agreement with BioPharma, quarterlydifferences between the calculated optional reduction amounts and the repayment schedule amounts are rescheduled for payment after 2016 and any suchdeferred payments will remain subject to continued application of the quarterly ceiling in amounts due established by the calculated threshold for royaltybased on quarterly Vascepa revenues. No additional interest expense or liability is incurred as a result of such deferred repayments and no cliff payment of theremaining balance is due except in the event of Company default or Company change of control. The agreement does not expire until $150.0 million inaggregate has been repaid. We can prepay an amount equal to $150.0 million less any previously repaid amount. 105Table of ContentsWe currently estimate that Vascepa revenue levels will not be high enough in each quarter to support repayment to BioPharma in accordance with thresholdamounts in the repayment schedule and that such payments will remain subject to the continued application of the calculated threshold for royalty based onquarterly Vascepa revenues.Concurrent with our supply agreement with Chemport entered into in 2011 for the supply of API materials for Vascepa, we agreed to make anon-controlling minority share equity investment in the supplier of up to $3.3 million. We invested $1.7 million under this agreement in July 2011 and theremaining $1.6 million during 2012. In September 2013, we entered into an equity sale and purchase agreement between this supplier and a third party inwhich we agreed to sell approximately $1.3 million of our investment in the supplier to the third party at cost. This transaction closed in the first quarter of2014. In August 2014, we entered into a second equity sale and purchase agreement between this supplier and another third party in which we agreed to sellapproximately $1.0 million of our remaining investment. This transaction closed in the fourth quarter of 2014. The remaining carrying amount of$0.2 million as of December 31, 2016 and 2015, respectively, is included in other long term assets and is accounted for under the cost method.Under the 2004 share repurchase agreement with Laxdale Limited, or Laxdale, upon approval of Vascepa by the FDA on July 26, 2012, we wererequired to make a milestone payment to Laxdale of £7.5 million. We made this payment in 2012 and capitalized this Laxdale milestone payment of$11.6 million as a component of other long term assets. This long-term asset is being amortized over the estimated useful life of the intellectual property weacquired from Laxdale and we recognized amortization expense of $0.6 million in each of the years ended December 31, 2016 and 2015. Also under theLaxdale agreement, upon receipt of marketing approval in Europe for the first indication for Vascepa (or first indication of any product containing AmarinNeuroscience Limited intellectual property acquired from Laxdale in 2004), we must make an aggregate stock or cash payment to the former shareholders ofLaxdale (at the sole option of each of the sellers) of £7.5 million (approximately $9.3 million as of December 31, 2016). Additionally, upon receipt of amarketing approval in the United States or Europe for a further indication of Vascepa (or further indication of any other product using Amarin NeuroscienceLimited intellectual property), we must make an aggregate stock or cash payment (at the sole option of each of the sellers) of £5 million (approximately$6.2 million as of December 31, 2016) for each of the two potential market approvals (i.e. £10 million maximum, or approximately $12.3 million as ofDecember 31, 2016).We do not enter into financial instruments for trading or speculative purposes. As of December 31, 2016 and 2015, we had no outstanding forwardexchange contracts.Off-Balance Sheet ArrangementsWe do not have any special purpose entities or other off-balance sheet arrangements.Shelf Registration StatementOn March 29, 2014, the universal shelf registration statement on Form S-3 (Registration No. 333-173132) that we had filed with the SEC on March 29,2011 expired. On August 7, 2014, we filed with the SEC a new universal shelf registration statement on Form S-3, which provides for the offer, from time totime, of up to $300,000,000 of: ordinary shares, which may be represented by American Depositary Shares; preference shares, which may be represented byAmerican Depositary Shares; senior or subordinated debt securities; warrants to purchase any of these securities; and any combination of these securities,individually or as units. Following our public offering of 24,265,000 ADSs in August 2016, we have $230.8 million worth of securities available for issuanceunder this registration statement. The addition of any newly issued equity securities into the market may be dilutive to existing stockholders and newissuances by us or sales by our selling security holders could have an adverse effect on the price of our securities. 106Table of ContentsItem 7A.Quantitative and Qualitative Disclosures about Market RiskWe are exposed to market risks, which include changes in interest rates. We do not use derivative financial instruments in our investment portfolio, andother than in 2013, we enter into no foreign exchange contracts. Our investments meet high credit quality and diversification standards, as specified in ourinvestment policy.Foreign Currency Exchange Risk. Our results of operations and cash flows are subject to fluctuations due to changes in the Euro, Sterling and Yen. Themajority of cash and cash equivalents and the majority of our vendor relationships are denominated in U.S. dollars. We therefore believe that the risk of asignificant impact on our operating income from foreign currency fluctuations is not substantial. From time to time, we maintain a small amount of our cashand cash equivalents in Euro and Pound Sterling. We purchase a portion of our supply from Novasep based on a U.S. dollar to Euro exchange rate and assuch, remain subject to currency fluctuation risk for such purchases.Interest Rate Risk. We believe that we are not exposed to significant interest rate risk through market value fluctuations of balance sheet items (i.e.,price risk) or through changes in interest income or expenses (i.e., re-financing or re-investment risk). Interest rate risk mainly arises through interest bearingliabilities and assets. We invest funds not needed for near-term operating expenses in diversified short-term investments, consisting primarily of investmentgrade securities. As of December 31, 2016, the fair value of our cash and cash equivalents maturing in one year or less was $98.3 million and represented100% of our cash, cash equivalents and investment portfolio. A hypothetical 50 basis point change in interest rates would not result in a material decrease orincrease in the fair value of our securities due to the general short-term nature of our investment portfolio. Item 8.Financial Statements and Supplementary DataOur consolidated financial statements are annexed to this report beginning on page F-1. Item 9.Changes in and Disagreements with Accountants on Accounting and Financial DisclosureNone. Item 9A.Controls and ProceduresEvaluation of Disclosure Controls and ProceduresWe maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in the reports that we file orsubmit under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is (1) recorded, processed, summarized, and reported within the timeperiods specified in the SEC’s rules and forms and (2) accumulated and communicated to our management, including our Principal Executive Officer andPrincipal Financial Officer, to allow timely decisions regarding required disclosure.As of December 31, 2016 (the “Evaluation Date”), our management, with the participation of our Principal Executive Officer and Principal FinancialOfficer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Ourmanagement recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achievingtheir objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. OurPrincipal Executive Officer and Principal Financial Officer have concluded based upon the evaluation described above that, as of the Evaluation Date, ourdisclosure controls and procedures were effective at the reasonable assurance level.Management’s Report on Internal Control over Financial ReportingOur management is responsible for establishing and maintaining adequate internal control over financial reporting for our company. Internal controlover financial reporting is defined in Rules 13a-15(f) and 15(d)-15(f) 107Table of Contentspromulgated under the Exchange Act as a process designed by, or under the supervision of, our Principal Executive Officer and Principal Financial Officerand effected by our board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting andthe preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies andprocedures that: • pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and disposition of our assets; • provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance withgenerally accepted accounting principles; • provide reasonable assurance that our receipts and expenditures are being made only in accordance with authorization of our management anddirectors; and • provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our assets that couldhave a material effect on the financial statements.Because of inherent limitations, internal controls over financial reporting may not prevent or detect misstatements. Projections of any evaluation ofeffectiveness to future periods are subject to the risks that controls may become inadequate because of changes in conditions or that the degree of compliancewith the policies or procedures may deteriorate.Our management, including our Principal Executive Officer and Principal Financial Officer, has conducted an evaluation of the effectiveness of ourinternal control over financial reporting as of December 31, 2016. In conducting this evaluation, we used the criteria set forth by the Committee ofSponsoring Organizations of the Treadway Commission (COSO), in Internal Control-Integrated Framework (2013).Based upon this evaluation and those criteria, management believes that, as of December 31, 2016, our internal controls over financial reporting wereeffective.Ernst & Young LLP, our independent registered public accounting firm, has audited our consolidated financial statements and the effectiveness of ourinternal control over financial reporting as of December 31, 2016. This report appears below.Changes in Internal Control over Financial ReportingThere were no changes in our internal control over financial reporting during the fourth quarter of 2016 that have materially affected, or are reasonablylikely to materially affect, our internal control over financial reporting. 108Table of ContentsREPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMThe Board of Directors and Shareholders ofAmarin Corporation plcWe have audited Amarin Corporation plc’s internal control over financial reporting as of December 31, 2016, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). AmarinCorporation plc’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness ofinternal control over financial reporting included in the accompanying Report of Management on Internal Controls over Financial Reporting. Ourresponsibility 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 thatwe plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all materialrespects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testingand evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considerednecessary 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 reportingand the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal controlover financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairlyreflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permitpreparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are beingmade only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention ortimely 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 ofeffectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliancewith the policies or procedures may deteriorate.In our opinion, Amarin Corporation plc maintained, in all material respects, effective internal control over financial reporting as of December 31, 2016, basedon the COSO criteria.We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheetsof Amarin Corporation plc as of December 31, 2016 and 2015 and the related consolidated statements of operations, stockholders’ deficit and cash flows foreach of the three years ended December 31, 2016 of Amarin Corporation plc and our report dated March 1, 2017 expressed an unqualified opinion thereon./s/ Ernst & Young LLPMetroPark, New JerseyMarch 1, 2017 109Table of ContentsItem 9B.Other InformationEntry into Rule 10b5-1 Trading PlansOur policy governing transactions in our securities by our directors, officers and employees permits our officers, directors and certain other persons toenter into trading plans complying with Rule 10b5-1 under the Securities Exchange Act of 1934, as amended.

F-6Table of ContentsAMARIN CORPORATION PLCNOTES TO CONSOLIDATED FINANCIAL STATEMENTS(1) Nature of Business and Basis of PresentationNature of BusinessAmarin Corporation plc (“Amarin” or the “Company”) is a biopharmaceutical company with expertise in lipid science focused on the commercialization anddevelopment of therapeutics to improve cardiovascular health.The Company’s lead product, Vascepa (icosapent ethyl) capsules, is approved by the U.S. Food and Drug Administration, or FDA, for use as an adjunct todiet to reduce triglyceride levels in adult patients with severe (TG 500 mg/dL) hypertriglyceridemia. Vascepa is available in the United States byprescription only. In January 2013, the Company began selling and marketing 1-gram size Vascepa capsules in the United States, and in October 2016,introduced a smaller 0.5-gram size capsule. In August 2015, in addition to marketing Vascepa for severe hypertriglyceridemia, the Company commencedmarketing Vascepa for use in adult patients with mixed dyslipidemia, as an adjunct to diet and an add-on to statin therapy in patients who despite statintherapy have high triglycerides (TGs 200 mg/dL and £500 mg/dL), which the Company also refers to as persistently high triglycerides. This expandedpromotion of Vascepa commenced pursuant to a federal court order and is continuing pursuant to an agreement among the Company, the FDA and the U.S.government. The Company sells Vascepa principally to a limited number of major wholesalers, as well as selected regional wholesalers and specialtypharmacy providers, or collectively, its Distributors or its customers, that in turn resell Vascepa to retail pharmacies for subsequent resale to patients andhealthcare providers. The Company markets Vascepa through its direct sales force of approximately 150 sales professionals, including sales representativesand their managers. In May 2014, Kowa Pharmaceuticals America, Inc. commenced co-promotion of Vascepa in accordance with a co-promotion agreementwith the Company. Kowa Pharmaceuticals America, Inc. co-promotes Vascepa through its no less than 250 sales representatives who now devote a substantialportion of their time to promoting Vascepa in conjunction with the promotion of Kowa Pharmaceutical America, Inc.’s primary product, a branded statin forpatients with high cholesterol. The Company operates in one business segment.The Company is also developing Vascepa for FDA approval of potential additional indications for use. In particular, the Company is conducting acardiovascular outcomes study of Vascepa, titled REDUCE-IT (Reduction of Cardiovascular Events with EPA—Intervention Trial). The REDUCE-IT study,which commenced in 2011 and completed patient enrollment and randomization of 8,175 individual patients in 2016, is designed to evaluate the efficacy ofVascepa in reducing major cardiovascular events in a high-risk patient population on statin therapy.Basis of PresentationThe consolidated financial statements included herein have been prepared by the Company in accordance with accounting principles generally accepted inthe United States of America (the “U.S.” or the “United States”) and pursuant to the rules and regulations of the Securities and Exchange Commission, or theSEC.The consolidated financial statements reflect all adjustments of a normal and recurring nature that, in the opinion of management, are necessary to presentfairly the Company’s financial position, results of operations and cash flows for the periods indicated. The preparation of the Company’s consolidatedfinancial statements in conformity with U.S. Generally Accepted Accounting Principles (“GAAP”) requires management to make estimates and assumptionsthat affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reportedamounts of revenues and expenses during the reporting period. The results of operations for the years ended December 31, 2016, 2015 and 2014 are notnecessarily indicative of the results for any future period. Certain numbers presented throughout this document may not add precisely to the totals provideddue to rounding. Absolute and percentage changes are F-7®Table of Contentscalculated using the underlying amounts in thousands. Certain prior year balances have been reclassified to conform to the current year presentation dueprimarily to the Company’s adoption of recent accounting pronouncements related to the presentation of debt issuance costs and excess tax benefits, as wellas its inclusion of additional required disclosure related to (provision for) benefit from income taxes. These reclassifications do not have a material impact onthe Company’s consolidated financial statements.The accompanying consolidated financial statements of the Company and subsidiaries have been prepared on a basis which assumes that the Company willcontinue as a going concern, which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business.At December 31, 2016, the Company had current assets of $146.3 million, including cash and cash equivalents of $98.3 million. Cash and cash equivalentsas of December 31, 2016 includes net proceeds of approximately $64.6 million resulting from the issuance of 24,265,000 American Depositary Shares, orADSs, as part of a public offering completed in August 2016 (see Note 10—Equity). The Company’s consolidated balance sheets also include long-term debtfrom royalty-bearing instrument and exchangeable senior notes. The terms of the January 2012 3.5% exchangeable senior notes due 2032, or the 2012 Notes,are such that they may be redeemed by the Company on or after January 19, 2017 and may be put back to the Company by the holders on each of January 19,2017, 2022 and 2027 for cash equal to 100% of the principal amount plus any accrued and unpaid interest. The 2012 Notes are exchangeable under certaincircumstances into cash, American Depositary Shares, or ADSs, or a combination of cash and ADSs, at the Company’s election. Accordingly, $15.1 million inprincipal amount of 2012 Notes represents a short-term claim on the liquid assets of the Company as of December 31, 2016. In September 2016, the Companymandatorily exchanged $118.7 million in aggregate principal amount of May 2014 3.5% exchangeable senior notes due 2032, or the 2014 Notes, and$31.3 million in aggregate principal amount of November 2015 3.5% exchangeable senior notes due 2032, or the 2015 Notes, into ADSs such that they wereretired in full, and derecognized the related derivative liabilities. In January 2017, holders of the 2012 Notes exercised their option to put the 2012 Notes tothe Company for cash. As a result, the Company repurchased approximately $15.0 million in aggregate principal amount of 2012 Notes, such that$0.1 million in principal amount of 2012 Notes currently remains outstanding. In contemplation of this repurchase, the Company issued $30.0 million inaggregate principal amount of January 2017 3.5% exchangeable senior notes due 2047, or the 2017 Notes. The Company has initiated the process to redeemthe remaining $0.1 million of 2012 Notes, which is expected to be completed in the first quarter of 2017. Refer to Note 8—Debt and Note 18—SubsequentEvents for further discussion.The Company believes its cash and cash equivalents will be sufficient to fund its projected operations through the results of the REDUCE-IT study, which weanticipate will be available mid-2018. Depending on the level of cash generated from operations, additional capital may be required to sustain operations,fund debt obligations or expand promotion of Vascepa as contemplated following anticipated successful results of the REDUCE-IT study. The Companyanticipates that annual net cash outflows in future periods will be variable.(2) Significant Accounting PoliciesPrinciples of ConsolidationThe consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactionshave been eliminated in consolidation.Use of EstimatesAccounting estimates are based on historical experience and other factors that are considered reasonable under the circumstances. Estimates are used indetermining such items as provisions for sales returns, rebates and incentives, chargebacks, and other sales allowances; depreciable/amortizable lives; assetimpairments; valuation allowance on deferred taxes; probabilities of achievement of performance conditions for certain equity awards; F-8Table of Contentsamounts recorded for licensing revenue; contingencies and accruals; and valuations of derivative and long-term debt instruments. Because of theuncertainties inherent in such estimates, actual results may differ from these estimates. Management periodically evaluates estimates used in the preparationof the consolidated financial statements for continued reasonableness.Use of Forecasted Financial Information in Accounting EstimatesThe use of forecasted financial information is inherent in many of the Company’s accounting estimates including, but not limited to, determining theestimated fair values of derivatives, debt instruments and intangible assets, evaluating the need for valuation allowances for deferred tax assets, and assessingthe Company’s ability to continue as a going concern. Such forecasted financial information is comprised of numerous assumptions regarding the Company’sfuture revenues, cash flows, and operational results. Management believes that its financial forecasts are reasonable and appropriate based upon current factsand circumstances. Because of the inherent nature of forecasts, however, actual results may differ from these forecasts. Management regularly reviews theinformation related to these forecasts and adjusts the carrying amounts of the applicable assets prospectively, if and when actual results differ from previousestimates.Revenue RecognitionThe Company sells Vascepa principally to a limited number of major wholesalers, as well as selected regional wholesalers and specialty pharmacy providers,or collectively, its Distributors or its customers, that in turn resell Vascepa to retail pharmacies for subsequent resale to patients and healthcare providers.Patients are required to have a prescription in order to purchase Vascepa. In accordance with GAAP, the Company’s revenue recognition policy requires that:(i) there is persuasive evidence that an arrangement exists between the Company and the Distributor, (ii) delivery has occurred, (iii) collectability isreasonably assured and (iv) the price is fixed or determinable.The Company has contracts with its primary Distributors and delivery generally occurs when a Distributor receives Vascepa. The Company evaluates thecreditworthiness of each of its Distributors to determine whether revenues can be recognized upon delivery, subject to satisfaction of the other requirements,or whether recognition is required to be delayed until receipt of payment. In order to conclude that the price is fixed or determinable, the Company must beable to (i) calculate its gross product revenues from the sales to Distributors and (ii) reasonably estimate its net product revenues. The Company calculatesgross product revenues generally based on the wholesale acquisition cost that the Company charges its Distributors for Vascepa. The Company estimates itsnet product revenues by deducting from its gross product revenues (a) trade allowances, such as invoice discounts for prompt payment and distributor fees,(b) estimated government and private pay or rebates, chargebacks and discounts, such as Medicaid reimbursements, (c) reserves for expected product returnsand (d) estimated costs of incentives offered to certain indirect customers, including patients.Trade Allowances: The Company generally provides invoice discounts on Vascepa sales to its Distributors for prompt payment and pays fees fordistribution services, such as fees for certain data that Distributors provide to the Company. The payment terms for sales to Distributors generallyinclude a 2% discount for payment within 30 days while the fees for distribution services are based on contractual rates agreed with the respectiveDistributors. Based on judgment and experience, the Company expects its Distributors to earn these discounts and fees, and deducts the full amount ofthese discounts and fees from its gross product revenues and accounts receivable at the time such revenues are recognized.Rebates, Chargebacks and Discounts: The Company contracts with Medicaid, other government agencies and various private organizations, orcollectively, Third-party Payors, so that Vascepa will be eligible for purchase by, or partial or full reimbursement from, such Third-party Payors. TheCompany estimates the rebates, chargebacks and discounts it will provide to Third-party Payors and deducts these estimated amounts from its grossproduct revenues at the time the revenues are recognized. The Company estimates the rebates, chargebacks and discounts that it will provide to Third-party Payors based upon (i) the F-9Table of ContentsCompany’s contracts with these Third-party Payors, (ii) the government-mandated discounts applicable to government-funded programs,(iii) information obtained from the Company’s Distributors and (iv) information obtained from other third parties regarding the payor mix for Vascepa.Product Returns: The Company’s Distributors have the right to return unopened unprescribed Vascepa during the 18-month period beginningsix months prior to the labeled expiration date and ending twelve months after the labeled expiration date. The expiration date for Vascepa is threeyears after it has been converted into capsule form, which is the last step in the manufacturing process for Vascepa and generally occurs within a fewmonths before Vascepa is delivered to Distributors. The Company estimates future product returns on sales of Vascepa based on: (i) data provided tothe Company by its Distributors (including weekly reporting of Distributors’ sales and inventory held by Distributors that provided the Company withvisibility into the distribution channel in order to determine what quantities were sold to retail pharmacies and other providers), (ii) informationprovided to the Company from retail pharmacies, (iii) data provided to the Company by a third-party data provider which collects and publishesprescription data, and other third parties, (iv) historical industry information regarding return rates for similar pharmaceutical products, (v) theestimated remaining shelf life of Vascepa previously shipped and currently being shipped to Distributors and (vi) contractual agreements intended tolimit the amount of inventory maintained by the Company’s Distributors.Other Incentives: Other incentives that the Company offers to indirect customers include co-pay mitigation rebates provided by the Company tocommercially insured patients who have coverage for Vascepa and who reside in states that permit co-pay mitigation programs. The Company’s co-paymitigation program is intended to reduce each participating patient’s portion of the financial responsibility for Vascepa’s purchase price to a specifieddollar amount. Based upon the terms of the program and information regarding programs provided for similar specialty pharmaceutical products, theCompany estimates the average co-pay mitigation amounts and the percentage of patients that it expects to participate in the program in order toestablish its accruals for co-pay mitigation rebates and deducts these estimated amounts from its gross product revenues at the time the revenues arerecognized. The Company adjusts its accruals for co-pay mitigation rebates based on actual redemption activity and estimates regarding the portion ofissued co-pay mitigation rebates that it estimates will be redeemed.The following table summarizes activity in each of the net product revenue allowance and reserve categories described above for the years endedDecember 31, 2016 and 2015: In thousands TradeAllowances Rebates,Chargebacksand Discounts ProductReturns OtherIncentives Total Balance as of January 1, 2015 $2,207 $3,610 $481 $792 $7,090 Provision related to current period sales 14,986 32,591 342 8,310 56,229 Provision related to prior period sales (174) (70) (205) — (449) Credits/payments made for current period sales (10,690) (22,710) — (7,226) (40,626) Credits/payments made for prior period sales (2,033) (3,540) (83) (792) (6,448) Balance as of December 31, 2015 $4,296 $9,881 $535 $1,084 $15,796 Provision related to current period sales 22,952 69,370 583 11,696 104,601 Provision related to prior period sales (87) (450) — — (537) Credits/payments made for current period sales (19,213) (48,719) — (9,815) (77,747) Credits/payments made for prior period sales (4,205) (9,167) (259) (1,284) (14,915) Balance as of December 31, 2016 $3,743 $20,915 $859 $1,681 $27,198 Such net product revenue allowances and reserves are included within accrued expenses and other current liabilities within the consolidated balance sheets,with the exception of trade allowances and chargebacks, which are included within accounts receivable, net as discussed below. F-10Table of ContentsMultiple-Element Arrangements and Licensing RevenueWhen evaluating multiple-element arrangements, the Company identifies the deliverables included within the agreement and evaluates which deliverablesrepresent separate units of accounting based on whether the delivered element has stand-alone value to the customer or if the arrangement includes a generalright of return for delivered items.The consideration received is allocated between each of the separable elements in the arrangement using the relative selling price method. The selling priceused for each separable element will be based on vendor specific objective evidence (“VSOE”) if available, third-party evidence if VSOE is not available, orestimated selling price if neither VSOE nor third-party evidence is available. Revenue is then recognized as each of the separable elements to which therevenue has been allocated is delivered.The Company may receive up-front, non-refundable payments when licensing its intellectual property in conjunction with research, development andcommercialization agreements. In determining the units of accounting, management evaluates whether the license has stand-alone value from theundelivered elements to the collaborative partner based on the consideration of the relevant facts and circumstances for each arrangement. Factors consideredin this determination include the stage of development of the license delivered, research and development capabilities of the partner and the ability ofpartners to develop and commercialize Vascepa independent of the Company.When management believes the license to its intellectual property does not have stand-alone value from the other deliverables to be provided in thearrangement, the Company generally recognizes revenue attributable to the license over the Company’s contractual or estimated performance period. Anyunrecognized portion of license revenue is classified within deferred revenue in the accompanying consolidated balance sheets. When management believesthe license to its intellectual property has stand-alone value, the Company recognizes revenue attributed to the license upon delivery. The periods overwhich revenue is recognized is subject to estimates by management and may change over the course of the agreement. Such a change could have a materialimpact on the amount of revenue the Company records in future periods.MilestonesContingent consideration from activities that is earned upon the achievement of a substantive milestone is recognized in its entirety in the period in whichthe milestone is achieved. At the inception of each arrangement that includes milestone payments, the Company evaluates whether each milestone issubstantive. This evaluation includes an assessment of whether: (a) the consideration is commensurate with either (1) the entity’s performance to achieve themilestone, or (2) the enhancement of the value of the delivered item(s) as a result of a specific outcome resulting from the entity’s performance to achieve themilestone, (b) the consideration relates solely to past performance and (c) the consideration is reasonable relative to all of the deliverables and payment termswithin the arrangement. The Company evaluates factors such as the scientific, clinical, regulatory, commercial and other risks that must be overcome toachieve the respective milestone, the level of effort and investment required and whether the milestone consideration is reasonable relative to all deliverablesand payment terms in the arrangement in making this assessment.See Note 17—Development, Commercialization and Supply Agreement for further information regarding licensing revenue and milestones primarily relatedto the Company’s multiple-element arrangement with Eddingpharm (Asia) Macao Commercial Offshore Limited.Distribution CostsThe Company records distribution costs related to shipping product to its customers, primarily through the use of common carriers or external distributionservices, in cost of goods sold. F-11Table of ContentsCash and Cash Equivalents and Restricted CashCash and cash equivalents consist of cash, deposits with banks and short-term highly liquid money market instruments with remaining maturities at the dateof purchase of 90 days or less. Restricted cash represents cash and cash equivalents pledged to guarantee repayment of certain expenses which may beincurred for business travel under corporate credit cards held by employees.Accounts Receivable, netAccounts receivable, net, comprised of trade receivables, are generally due within 30 days and are stated at amounts due from customers. The Companyrecognizes an allowance for losses on accounts receivable in an amount equal to the estimated probable losses net of any recoveries. The allowance is basedprimarily on assessment of specific identifiable customer accounts considered at risk or uncollectible, as well as an analysis of current receivables aging andexpected future write-offs. The expense associated with the allowance for doubtful accounts is recognized as selling, general, and administrative expense.The Company has not historically experienced any credit losses.The following table summarizes the impact of accounts receivable reserves on the gross trade accounts receivable balances as of December 31, 2016 and2015: In thousands December 31, 2016 December 31, 2015 Gross trade accounts receivable $24,127 $18,270 Trade allowances (3,743) (4,296) Chargebacks (387) (148) Allowance for doubtful accounts (12) — Accounts receivable, net $19,985 $13,826 InventoryEffective April 2016, the Company adopted Accounting Standards Update (“ASU”) No. 2015-11, Inventory (Topic 330)—Simplifying the Measurement ofInventory, which simplifies the subsequent measurement of inventories by replacing the lower of cost or market test with a lower of cost and net realizablevalue test and, as such, began to state inventories at the lower of cost or net realizable value. Such adoption had no impact on the carrying value of inventory.Cost is determined based on actual cost using the average cost method. An allowance is established when management determines that certain inventoriesmay not be saleable. If inventory cost exceeds expected net realizable value due to obsolescence, damage or quantities in excess of expected demand,changes in price levels or other causes, the Company will reduce the carrying value of such inventory to net realizable value and recognize the difference as acomponent of cost of goods sold in the period in which it occurs. The Company capitalizes inventory purchases of saleable product from approved supplierswhile inventory purchases from suppliers prior to regulatory approval are included as a component of research and development expense. The Companyexpenses inventory identified for use as marketing samples when they are packaged. The average cost reflects the actual purchase price of Vascepa activepharmaceutical ingredient, or API.Property, Plant and EquipmentThe Company provides for depreciation and amortization using the straight-line method by charges to operations in amounts that depreciate the cost of thefixed asset over its estimated useful life. The estimated useful lives, by asset classification, are as follows: Asset Classification Useful LivesComputer equipment and software 3 - 5 yearsFurniture and fixtures 5 yearsLeasehold improvements Lesser of useful life or lease term F-12Table of ContentsUpon retirement or sale of assets, the cost of the assets disposed and the related accumulated depreciation are removed from the consolidated balance sheetand any resulting gain or loss is credited or expensed to operations. Repairs and maintenance costs are expensed as incurred.Long-Lived Asset ImpairmentThe Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets maynot be recoverable. Recoverability of these assets is determined by comparing the forecasted undiscounted net cash flows of the operation to which the assetsrelate to their carrying amount. If impairment is indicated, the assets are written down to fair value. Fair value is determined based on discounted forecastedcash flows or appraised values, depending on the nature of the assets.Intangible Asset, netIntangible asset, net consists of a milestone payment paid to the former shareholders of Laxdale Limited related to the 2004 acquisition of the rights toVascepa, which is the result of Vascepa receiving marketing approval for the first indication and is amortized over its estimated useful life on a straight-linebasis. See Note 9—Commitments and Contingencies for further information regarding other obligations related to the acquisition of Laxdale Limited.Beneficial Conversion FeaturesThe Company issued Series A preference shares in a private placement transaction executed in two tranches that each contain a conversion feature wherebysuch shares are convertible into ordinary shares at a fixed rate. The conversion price on the date of issuance was less than the market price of the Company’sordinary shares. It was determined that these discounts represent contingent beneficial conversion features, which were valued based on the differencebetween the conversion price and the market price of the ordinary shares on the date of issuance, which is the commitment date. These features are analogousto preference dividends and were each recorded as a non-cash return to preferred shareholders through accumulated deficit upon the earliest possible date ofconversion, which occurred in the three months ended June 30, 2015 upon effectiveness of the related resale Registration Statement on Form S-3 and in thethree months ended September 30, 2015 upon shareholder approval received at the Company’s Annual General Meeting of Shareholders. See Note 10—Equity for further discussion.Costs for Patent Litigation and Legal ProceedingsCosts for patent litigation or other legal proceedings are expensed as incurred and included in selling, general and administrative expenses.Research and Development CostsThe Company charges research and development costs to operations as incurred. Research and development expenses are comprised of costs incurred by theCompany in performing research and development activities, including: salary and benefits; stock-based compensation expense; laboratory supplies andother direct expenses; contractual services, including clinical trial and pharmaceutical development costs; commercial supply investment in its drugcandidates; and infrastructure costs, including facilities costs and depreciation expense. In addition, research and development costs include the costs ofproduct supply received from suppliers when such receipt by the Company is prior to regulatory approval of the supplier.Selling, General and Administrative CostsThe Company charges selling, general and administrative costs to operations as incurred. Selling, general and administrative costs include costs of salaries,programs and infrastructure necessary for the general conduct of F-13Table of Contentsthe Company’s business, including those incurred as a result of the commercialization of Vascepa in the United States as well as co-promotion fees payable toKowa Pharmaceuticals America, Inc.Income TaxesDeferred tax assets and liabilities are recognized for the future tax consequences of differences between the carrying amounts and tax bases of assets andliabilities and operating loss carryforwards and other attributes using enacted rates expected to be in effect when those differences reverse. Valuationallowances are provided against deferred tax assets that are not more likely than not to be realized.The Company provides reserves for potential payments of tax to various tax authorities or does not recognize tax benefits related to uncertain tax positionsand other issues. Tax benefits for uncertain tax positions are based on a determination of whether a tax benefit taken by the Company in its tax filings orpositions is more likely than not to be realized, assuming that the matter in question will be decided based on its technical merits. The Company’s policy isto record interest and penalties in the provision for income taxes.The Company regularly assesses its ability to realize deferred tax assets. Changes in historical earnings performance and future earnings projections, amongother factors, may cause the Company to adjust its valuation allowance on deferred tax assets, which would impact the Company’s income tax expense in theperiod in which it is determined that these factors have changed.In April 2016, the Company adopted ASU No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based PaymentAccounting, which changes the accounting for certain aspects of share-based payments to employees. One aspect of the standard requires that excess taxbenefits and deficiencies that arise upon vesting or exercise of share-based payments be recognized as an income tax benefit and expense in the incomestatement. Previously, such amounts were recognized as an increase and decrease in additional paid-in capital. This aspect of the standard was adoptedprospectively and, accordingly, the provision for income taxes for the year ended December 31, 2016 includes $0.4 million of excess tax deficiencies arisingfrom share-based payments. Additionally, the new standard requires that historical excess tax benefits that were not previously recognized because the relatedtax deduction had not reduced current taxes payable should be recognized on a modified retrospective basis as a cumulative-effect adjustment to retainedearnings as of the beginning of the annual period of adoption. Consequently, the Company recognized deferred tax assets of approximately $1.6 millionrelating to excess tax benefits on stock-based compensation outstanding as of December 31, 2015, with a corresponding cumulative-effect adjustment toaccumulated deficit. The new standard also amends the presentation of employee share-based payment-related items in the statement of cash flows byrequiring that: (i) excess income tax benefits and deficiencies be classified in cash flows from operating activities, and (ii) cash paid to taxing authoritiesarising from the withholding of shares from employees be classified as cash flows from financing activities. The Company adopted the aspects of the standardaffecting cash flow presentation retrospectively and, accordingly, reclassified $0.7 million of excess tax benefit and $2.3 million of excess tax provision fromcash flows provided by financing activities to cash flows used in operating activities in the consolidated statement of cash flows for the years endedDecember 31, 2015 and 2014, respectively, to conform to the current year presentation. The presentation requirement for cash flows related to taxes paid forwithheld shares had no impact to any of the periods presented in the consolidated statement of cash flows since such payments have historically beenpresented as a financing activity.The Company’s and its subsidiaries’ income tax returns are periodically examined by various tax authorities. The Company is currently under audit by theUnited States Internal Revenue Service (IRS) for the years 2013 to 2014. Although the outcome of tax audits is always uncertain and could result insignificant cash tax payments, the Company does not believe the outcome of these audits will have a material adverse effect on the Company’s consolidatedfinancial position or results of operations. F-14Table of ContentsDerivative InstrumentsDerivative financial liabilities are recorded at fair value, with gains and losses arising for changes in fair value recognized in the consolidated statement ofoperations at each period end while such instruments are outstanding. If the Company issues shares to discharge the liability, the derivative financial liabilityis derecognized and common stock and additional paid-in capital are recognized on the issuance of those shares. Warrants are valued using a Black-Scholesoption pricing model. The long-term debt redemption features are valued using probability-weighted models incorporating management estimates forpotential change in control, and by determining the fair value of the debt with and without the change in control provision included.If the terms of warrants that initially require the warrant to be classified as a derivative financial liability lapse, the derivative financial liability is reclassifiedout of financial liabilities into equity at its fair value on that date. The cash proceeds received from exercises of warrants are recorded in common stock andadditional paid-in capital.Loss per ShareBasic net loss per share is determined by dividing net loss by the weighted average shares of common stock outstanding during the period. Diluted net lossper share is determined by dividing net loss by diluted weighted average shares outstanding. Diluted weighted average shares reflects the dilutive effect, ifany, of potentially dilutive common shares, such as common stock options and warrants calculated using the treasury stock method and convertible notesusing the “if-converted” method. In periods with reported net operating losses, all common stock options and warrants are deemed anti-dilutive such thatbasic net loss per share and diluted net loss per share are equal. However, in certain periods in which there is a gain recorded pursuant to the change in fairvalue of the warrant derivative liability, for diluted net loss per share purposes, the impact of such gains is reversed and the treasury stock method is used todetermine diluted net loss per share.The Company’s preferred stock is entitled to receive dividends on an as-if-converted basis in the same form as dividends actually paid on common shares.Accordingly, the preferred stock is considered a participating security and the Company is required to apply the two-class method to consider the impact ofthe preferred stock on the calculation of basic and diluted earnings per share. The Company is currently in a net loss position and is therefore not required topresent the two-class method, however, in the event the Company is in a net income position, the two-class method must be applied by allocating all earningsduring the period to common shares and preferred stock based on their contractual entitlements assuming all earnings were distributed.The calculation of net loss and the number of shares used to compute basic and diluted net loss per share for the years ended December 31, 2016, 2015 and2014 are as follows: In thousands 2016 2015 2014 Net loss $(86,350) $(115,204) $(56,364) Preferred stock purchase option (see Note 10—Equity) — (868) — Preferred stock beneficial conversion features (see Note 10—Equity) — (32,987) — Net loss applicable to common shareholders—basic (86,350) (149,059) (56,364) Gain on warrant derivative liability — — (6,775) Net loss—diluted (86,350) (149,059) (63,139) Net loss per share—basic $(0.41) $(0.83) $(0.32) Weighted average shares outstanding—basic 211,874 180,654 173,719 Effect of dilutive warrants — — 105 Weighted average shares outstanding—diluted 211,874 180,654 173,824 Net loss per share—diluted $(0.41) $(0.83) $(0.36) F-15Table of ContentsFor the years ended December 31, 2016, 2015 and 2014, the following potentially dilutive securities were not included in the computation of net loss pershare because the effect would be anti-dilutive: In thousands 2016 2015 2014 Stock options 21,188 17,818 10,670 Restricted stock and restricted stock units 10,143 10,887 2,256 Exchangeable senior notes (if converted) 1,714 59,407 49,215 Preferred stock (if converted) 32,818 32,818 — Debt InstrumentsDebt instruments are initially recorded at fair value, with coupon interest and amortization of debt issuance discounts recognized in the consolidatedstatement of operations as interest expense each period in which such instruments are outstanding. If the Company issues shares to discharge the liability, thedebt obligation is derecognized and common stock and additional paid-in capital are recognized on the issuance of those shares. The conversion features inthe 2012 Notes, and previously the 2014 Notes and 2015 Notes prior to the mandatory exchange, qualify for the exception from derivative accounting inaccordance with ASC 815-40. The 2012 Notes may be put to the Company by their holders for repurchase in cash. The 2012 Notes are exchangeable undercertain circumstances at the Company’s discretion, in any combination of ADSs or cash upon conversion and have been accounted for in accordance withASC 470-20. Under ASC 470-20, the fair value of the liability component of the 2012 Notes was determined and deducted from the initial proceeds todetermine the proceeds allocated to the conversion option, which has been recorded in equity. The difference between the initial fair value of the liabilitycomponent and the amount repayable was fully amortized over the expected term of the instrument. The conversion features in the 2014 Notes and 2015Notes could only have been settled in ADSs upon conversion and were therefore accounted for as part of the debt host.The conversion feature in the 2012 Notes, continues to be evaluated on a quarterly basis to determine if it still receives an exception from derivativeaccounting in accordance with ASC 815-40. The 2014 Notes were recognized initially at fair value as part of an extinguishment of a portion of the 2012Notes. As a result, the 2014 Notes were initially recognized at a discount of $27.9 million. The 2015 Notes were recognized initially at fair value as part ofthe issuance of new debt in November 2015. As a result, the 2015 Notes were initially recognized at a discount of $3.8 million. These discounts wereamortized through interest expense through the date of the mandatory exchange. See Note 8—Debt for further discussion.Stock-Based CompensationStock-based compensation cost is generally measured at the grant date, based on the fair value of the award, and is recognized as compensation expense overthe requisite service period. For awards with performance conditions, if the achievement of the performance conditions is deemed probable, the Companyrecognizes compensation expense based on the fair value of the award over the estimated service period. The Company reassesses the probability ofachievement of the performance conditions for such awards each reporting period.Concentration of Credit RiskFinancial instruments that potentially subject the Company to credit risk consist primarily of cash and cash equivalents and accounts receivable. TheCompany maintains substantially all of its cash and cash equivalents in financial institutions believed to be of high-credit quality.A significant portion of the Company’s sales are to wholesalers in the pharmaceutical industry. The Company monitors the creditworthiness of customers towhom it grants credit terms and has not experienced any credit losses. The Company does not require collateral or any other security to support credit sales.The Company’s top three customers accounted for 95% of gross product sales for each of the years ending December 31, 2016 and 2015, and represented96% and 95% of the gross accounts receivable balance as of December 31, 2016 and 2015, respectively. The Company has not experienced any write-offs ofits accounts receivable. F-16Table of ContentsConcentration of SuppliersThe Company has contractual freedom to source the API for Vascepa and has entered into supply agreements with multiple suppliers. The Company’s supplyof product for commercial sale and clinical trials is dependent upon relationships with third-party manufacturers and key suppliers, in particular threesuppliers of API for Vascepa.The Company cannot provide assurance that its efforts to procure uninterrupted supply of Vascepa API to meet market demand will continue to be successfulor that it will be able to renew current API supply agreements on favorable terms or at all. Significant alteration to or termination of the Company’s currentAPI supply chain or its failure to enter into new and similar agreements in a timely fashion, if needed, could have a material adverse effect on its business,condition (financial and other), prospects or results of operations.The Company currently has manufacturing agreements with three FDA-approved commercial API encapsulators for Vascepa manufacturing. Each of thesecompanies has qualified its manufacturing processes and is capable of manufacturing Vascepa. There can be no guarantee that these or other suppliers withwhich the Company may contract in the future to encapsulate API will remain qualified to manufacture the product to its specifications or that these and anyfuture suppliers will have the manufacturing capacity to meet anticipated demand for Vascepa.Foreign CurrencyAll subsidiaries use the U.S. dollar as the functional currency. Monetary assets and liabilities denominated in a foreign currency are remeasured into U.S.dollars at period-end exchange rates. Gains and losses from the remeasurement are included in other (expense) income, net, in the consolidated statements ofoperations. For transactions settled during the applicable period, gains and losses are included in other (expense) income, net, in the consolidated statementsof operations. Certain amounts payable pursuant to supply contracts are denominated in currencies other than the U.S. dollar.Debt Issuance CostsPrior to January 2016, debt issuance costs were initially recorded as a deferred cost and amortized to interest expense using the effective interest method overthe expected term of the related debt. Effective January 2016, the Company adopted ASU No. 2015-03, Interest—Imputation of Interest (Subtopic 835-30):Simplifying the Presentation of Debt Issuance Costs, and as such began recording debt issuance costs related to a recognized debt liability in theconsolidated balance sheet as a direct deduction from the carrying amount of that debt liability and amortized to interest expense using the effective interestmethod over the expected term of the related debt. As the standard is required to be adopted on a retrospective basis, the Company reclassified $1.9 million ofunderwriters’ fees and offering costs related to the 2014 Notes and 2015 Notes from other long-term assets to exchangeable senior notes, net of discount,within the consolidated balance sheet as of December 31, 2015. Unamortized debt issuance costs related to the extinguishment of debt are expensed at thetime the debt is extinguished and recorded in other (expense) income, net, in the consolidated statements of operations.Fair Value of Financial InstrumentsThe Company provides disclosure of financial assets and financial liabilities that are carried at fair value based on the price that would be received upon saleof an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements may beclassified based on the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities using the following three levels:Level 1—Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at themeasurement date. F-17Table of ContentsLevel 2—Inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in marketsthat are not active, inputs other than quoted prices that are observable for the asset or liability (i.e., interest rates, yield curves, etc.) and inputs that are derivedprincipally from or corroborated by observable market data by correlation or other means (market corroborated inputs).Level 3—Unobservable inputs that reflect the Company’s estimates of the assumptions that market participants would use in pricing the asset or liability.The Company develops these inputs based on the best information available, including its own data.The following tables present information about the Company’s assets and liabilities as of December 31, 2016 and 2015 that are measured at fair value on arecurring basis and indicate the fair value hierarchy of the valuation techniques the Company utilized to determine such fair value: December 31, 2016 In thousands Total Level 1 Level 2 Level 3 Asset: Cash equivalents—money markets $14,238 $14,238 $— $— December 31, 2015 In thousands Total Level 1 Level 2 Level 3 Asset: Cash equivalents—money markets $14,184 $14,184 $— $— Liabilities: Long-term debt derivative liabilities $8,170 $— $— $8,170 The carrying amounts of cash, cash equivalents, accounts payable and accrued liabilities approximate fair value because of their short-term nature. Thecarrying amounts and the estimated fair values of debt instruments as of December 31, 2016 and 2015 are as follows: December 31, 2016 December 31, 2015 In thousands CarryingValue EstimatedFair Value CarryingValue EstimatedFair Value Long-term debt from royalty-bearing instrument $85,155 $90,500 $91,512 $87,700 2012 Notes 15,107 15,174 15,107 13,637 2014 Notes — — 96,364 108,034 2015 Notes — — 27,134 28,448 The estimated fair value of the long-term debt from royalty-bearing instrument pursuant to the December 2012 financing is calculated utilizing the sameLevel 3 inputs utilized in valuing the related derivative liability (see Long-Term Debt Redemption Features below). The estimated fair value of the 2012Notes and 2014 Notes is calculated based on Level 1 quoted bond prices, while the estimated fair value of the 2015 Notes is calculated based on Level 2quoted bond prices for the 2014 Notes. The carrying value of the 2012 Notes as of December 31, 2016 and 2015 does not include a debt discount, as it hadbeen fully amortized as non-cash interest expense over the expected term of the 2012 Notes, which was calculated to be a period of twenty-four months. Thecarrying value of the 2014 Notes as of December 31, 2015 includes a debt discount of $24.1 million, which prior to mandatory exchange was beingamortized as non-cash interest expense over the expected term of the 2014 Notes, through January 2019. The carrying value of the 2015 Notes as ofDecember 31, 2015 includes a debt discount of $4.2 million, which prior to mandatory exchange was being amortized as non-cash interest expense over theexpected term of the 2015 Notes, through January 2019. The carrying values and related debt discounts of the 2014 Notes and 2015 Notes as of December 31,2015 reflect the retroactive reclassification of debt issuance costs per adoption of ASU No. 2015-03 as described in Note 8—Debt. The change in theestimated F-18Table of Contentsfair values of these liabilities from December 31, 2015 to December 31, 2016 is largely related to changes in the quoted bond prices and derecognition of themandatorily exchanged debt.Derivative LiabilitiesWarrant Derivative LiabilityThe Company’s warrant derivative liability (discussed in Note 7—Warrants and Warrant Derivative Liability) was carried at fair value and was classified asLevel 3 in the fair value hierarchy due to the use of significant unobservable inputs. During the year ended December 31, 2015 of the 8,087,388 warrantsoutstanding as of December 31, 2014, 1,844,585 warrants were exercised while the remaining 6,242,803 warrants expired and the related derivative liabilitywas extinguished. As such, no warrants were outstanding as of December 31, 2016.Long-Term Debt Redemption FeaturesThe Company’s December 2012 financing agreement with BioPharma Secured Debt Fund II Holdings Cayman LP (discussed in Note 8—Debt) contains aredemption feature whereby, upon a change of control, the Company would be required to repay $150.0 million, less any previously repaid amount. TheCompany determined this redemption feature to be an embedded derivative, which is carried at fair value and is classified as Level 3 in the fair valuehierarchy due to the use of significant unobservable inputs. The fair value of the embedded derivative was calculated using a probability-weighted modelincorporating management estimates of future revenues and for a potential change in control, and by determining the fair value of the debt with and withoutthe change in control provision included. The difference between the two was determined to be the fair value of the embedded derivative. As of December 31,2016, the fair value of the derivative was determined to be nil based on current assumptions, and the debt was valued by comparing debt issues of similarcompanies with (i) remaining terms of between 2.4 and 5.0 years, (ii) coupon rates of between 8.1% and 11.1% and (iii) market yields of between 11.9% and18.4%. As of December 31, 2015, the fair value of the derivative was determined to be $5.5 million, and the debt was valued by comparing debt issues ofsimilar companies with (i) remaining terms of between 2.0 and 7.3 years, (ii) coupon rates of between 6.6% and 12.5% and (iii) market yields of between13.0% and 30.7%. As such, the Company recognized a $5.5 million gain on change in fair value of derivative liability for the year ended December 31, 2016.The Company’s 2014 Notes and 2015 Notes each contained a redemption feature whereby, upon occurrence of a change in control, the Company would havebeen required to repurchase the notes. The Company determined these redemption features to be embedded derivatives, requiring bifurcation in accordancewith ASC 815. The derivatives were carried at fair value and were classified as Level 3 in the fair value hierarchy due to the use of significant unobservableinputs. The fair value of each embedded derivative was calculated using a probability-weighted model incorporating management estimates of theprobability of a change in control occurring, and by determining the fair value of the debt with and without the change in control provision included. Thedifference between the two was determined to be the fair value of the embedded derivative. As of December 31, 2016, derivatives related to the 2014 Notesand 2015 Notes were each derecognized, as the related debt hosts were exchanged into equity in September 2016. As of December 31, 2015, the fair values ofthe derivatives related to the 2014 Notes and 2015 Notes were determined to be $2.1 million and $0.6 million, respectively, and the debts were valued byusing (i) the estimated remaining term of the notes, (ii) a bond yield of 25.6%, (iii) a risk-free interest rate of 2.9% and (iv) volatility of 89.0%. As such, theCompany recognized a gain on change in fair value of derivative liability for the 2014 Notes and 2015 Notes of $2.1 million and $0.6 million, respectively,for the year ended December 31, 2016.Preferred Stock Purchase Option Derivative LiabilityPursuant to a pre-existing contractual right to participate in certain private placement transactions effected by the Company in connection with thesubscription agreement executed on March 5, 2015, the Company determined F-19Table of Contentsthat such right represented a derivative liability (see Note 10—Equity). This preferred stock purchase option derivative liability was carried at fair value andclassified as Level 3 in the fair value hierarchy due to the use of significant unobservable inputs. The fair value of this liability was calculated using a Black-Scholes model and was determined to be $0.9 million at inception. On March 30, 2015, this right was exercised and the liability was marked to fair valuethrough such date. The liability was then reclassified to permanent equity on such date.Any changes in the assumptions used to value the derivative liabilities, including the probability of a change in control, could result in a material change tothe carrying value of such liabilities.The change in the fair value of derivative liabilities for the years ended December 31, 2016 and 2015 is as follows: In thousands October2009Warrants Long-TermDebt DerivativeLiabilities Preferred StockPurchase Option Total Balance as of January 1, 2015 $119 $7,400 $— $7,519 Record initial fair value of derivative liability — 500 868 1,368 (Gain) loss on change in fair value of derivative liabilities (110) 270 946 1,106 Compensation income for change in fair value of warrants issued to formeremployees (9) — — (9) Transfer derivative liability to equity — — (1,814) (1,814) Balance as of December 31, 2015 $— $8,170 $— $8,170 Gain on change in fair value of derivative liabilities — (8,170) — (8,170) Balance as of December 31, 2016 $— $— $— $— Segment and Geographical InformationOperating segments are defined as components of an enterprise about which separate financial information is available that is evaluated on a regular basis bythe chief operating decision-maker, or decision making group, in deciding how to allocate resources to an individual segment and in assessing performanceof the segment. The Company currently operates in one business segment, which is the development and commercialization of Vascepa. A singlemanagement team that reports to the Company’s chief decision-maker, who is the Chief Executive Officer, comprehensively manages the business.Accordingly, the Company does not have separately reportable segments.Recent Accounting PronouncementsFrom time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board, or FASB, and are early adopted by theCompany or adopted as of the specified effective date.In January 2016, the Company adopted ASU No. 2015-03, Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt IssuanceCosts, which provides guidance on simplifying the presentation of debt issuance costs on the balance sheet. To simplify presentation of debt issuance costs,the amendments in ASU No. 2015-03 require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a directdeduction from the carrying amount of that debt liability, consistent with the treatment of debt discounts. The recognition and measurement guidance fordebt issuance costs are not affected by the amendments in this update. In accordance with ASU No. 2015-03, the Company applied the new guidance on aretrospective basis, wherein the consolidated balance sheet of each individual period presented was adjusted to reflect the period-specific effects of applyingthe new guidance. See Note 8—Debt.In April 2016, the Company adopted ASU No. 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory, which simplifies the subsequentmeasurement of inventories by replacing the lower of cost or market F-20Table of Contentstest with a lower of cost or net realizable value test. When evidence exists that the net realizable value of inventory is less than its cost (due to damage,physical deterioration, obsolescence, changes in price levels or other causes), the Company will recognize the difference as a component of cost of goodssold in the period in which it occurs. In accordance with ASU No. 2015-11, the Company applied the new guidance on a prospective basis with no impact onthe carrying amount of inventory.Also in April 2016, the Company adopted ASU No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-BasedPayment Accounting, which changes the accounting for certain aspects of share-based payments to employees. One aspect of the standard requires that excesstax benefits and deficiencies that arise upon vesting or exercise of share-based payments be recognized as an income tax benefit and expense in the incomestatement. Previously, such amounts were recognized as an increase and decrease in additional paid-in capital. This aspect of the standard was adoptedprospectively, and accordingly, the provision for income taxes for the year ended December 31, 2016 includes $0.4 million of excess tax deficiencies arisingfrom share-based payments. Additionally, the new standard requires that historical excess tax benefits that were not previously recognized because the relatedtax deduction had not reduced current taxes payable should be recognized on a modified retrospective basis as a cumulative-effect adjustment to retainedearnings as of the beginning of the annual period of adoption. Consequently, the Company recognized deferred tax assets of approximately $1.6 millionrelating to excess tax benefits on stock-based compensation outstanding as of December 31, 2015, with a corresponding cumulative-effect adjustment toaccumulated deficit. The new standard also amends the presentation of employee share-based payment-related items in the statement of cash flows byrequiring that: (i) excess income tax benefits and deficiencies be classified in cash flows from operating activities, and (ii) cash paid to taxing authoritiesarising from the withholding of shares from employees be classified as cash flows from financing activities. The Company adopted the aspects of the standardaffecting cash flow presentation retrospectively and, accordingly, reclassified $0.7 million of excess tax benefit and $2.3 million of excess tax provision fromcash flows provided by financing activities to cash flows used in operating activities in the consolidated statement of cash flows as of December 31, 2015 and2014, respectively, to conform to the current year presentation. The presentation requirement for cash flows related to taxes paid for withheld shares had noimpact to any of the periods presented in the consolidated statement of cash flows since such payments have historically been presented as a financingactivity.In December 2016, the Company adopted ASU No. 2014-15, Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure ofUncertainties about an Entity’s Ability to Continue as a Going Concern. ASU No. 2014-15 requires management to assess an entity’s ability to continue as agoing concern by incorporating and expanding upon certain principles that are currently in U.S. auditing standards. Specifically, the ASU (i) provides adefinition of the term substantial doubt, (ii) requires an evaluation every reporting period including interim periods, (iii) provides principles for consideringthe mitigating effect of management’s plans, (iv) requires certain disclosures when substantial doubt is alleviated as a result of consideration ofmanagement’s plans, (v) requires an express statement and other disclosures when substantial doubt is not alleviated and (vi) requires an assessment for aperiod of one year after the date that the financial statements are issued (or available to be issued). The Company believes that its cash and cash equivalentswill be sufficient to fund its projected operations through the results of the REDUCE-IT study, which it anticipates will be available mid-2018.The Company also considered the following recent accounting pronouncements which were not yet adopted as of December 31, 2016:In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which will replace numerous requirements in U.S.GAAP, including industry-specific requirements. This guidance provides a five step model to be applied to all contracts with customers, with an underlyingprinciple that an entity will recognize revenue to depict the transfer of goods or services to customers at an amount that the entity expects to be entitled to inexchange for those goods or services. ASU No. 2014-09 requires extensive quantitative and qualitative disclosures covering the nature, amount, timing anduncertainty of revenue and cash F-21Table of Contentsflows arising from customer contracts, including disclosures on significant judgments made when applying the guidance. This guidance is effective forannual reporting periods beginning after December 15, 2017 and interim periods therein. Early adoption is permitted for reporting periods and interimperiods therein, beginning after December 15, 2016. An entity can elect to apply the guidance under one of the following two methods: (i) retrospectively toeach prior reporting period presented, referred to as the full retrospective method, or (ii) retrospectively with the cumulative effect of initially applying thestandard recognized at the date of initial application in retained earnings, referred to as the modified retrospective method.The Company has substantially completed an initial impact assessment of the potential changes from adopting ASU No. 2014-09. The impact assessmentconsisted of a review of a representative sample of contracts, discussions with key stakeholders, and a cataloging of potential impacts on its financialstatements, accounting policies, financial control, and operations. The Company anticipates that the adoption of ASU No. 2014-09 will not have a materialimpact on product revenue from distributors and may have an impact on contract revenues generated by its license agreements: (i)Changes in the model for distinct licenses of functional intellectual property which may result in a timing difference of revenue recognition.Whereas revenue from these arrangements was previously recognized over a period of time pursuant to the multiple element arrangementguidance, revenue from these arrangements may now be recognized at point in time under the new guidance. (ii)Assessments of milestone payments, which are linked to events that are in the Company’s control, will result in variable consideration that maybe recognized at an earlier point in time under the new guidance, when it is probable that the milestone will be achieved without a significantfuture reversal of cumulative revenue expected.The Company has not yet completed its final review of the impact of this guidance; however, the Company anticipates applying the modified retrospectivemethod when implementing this guidance. The Company plans to adopt the new standard effective January 1, 2018. The Company continues to monitoradditional changes, modifications, clarifications or interpretations being undertaken by the FASB, which may impact its current conclusions.In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assetsand Financial Liabilities. The new guidance is intended to improve the recognition and measurement of financial instruments by requiring separatepresentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables) withinthe balance sheet or the accompanying notes to the financial statements, eliminating the requirement for public business entities to disclose the method(s)and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost within thebalance sheet, requiring public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes,requiring equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to bemeasured at fair value with changes in fair value recognized in net income, and requiring a reporting organization to present separately in othercomprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk (alsoreferred to as “own credit”) when the organization has elected to measure the liability at fair value in accordance with the fair value option for financialinstruments, among others. The new guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscalyears. The new guidance permits early adoption of the own credit provision. The Company is currently evaluating the accounting, transition and disclosurerequirements of the standard and cannot currently estimate the financial statement impact of adoption.In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The new guidance will require lessees to recognize a right-of-use asset and a leaseliability for virtually all of their leases (other than leases that meet the definition of a short-term lease). The liability will be equal to the present value of leasepayments. The F-22Table of Contentsasset will be based on the liability, subject to adjustment, such as for initial direct costs. Under the new guidance, lessor accounting is largely unchanged butcertain targeted improvements were made to align, where necessary, lessor accounting with the lessee accounting model and Topic 606, Revenue fromContracts with Customers. The new lease guidance also simplified the accounting for sale and leaseback transactions primarily because lessees mustrecognize lease assets and lease liabilities and therefore, will no longer be provided with a source of off-balance sheet financing. The new guidance iseffective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The Company iscurrently evaluating the accounting, transition and disclosure requirements of the standard and cannot currently estimate the financial statement impact ofadoption.In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (ReportingRevenue Gross versus Net), which clarifies that an entity is a principal when it controls the specified good or service before that good or service is transferredto the customer, and is an agent when it does not control the specified good or service before it is transferred to the customer. The new guidance is intended toimprove the operability and understandability of the implementation guidance on principal versus agent considerations. In April 2016, the FASB issued ASUNo. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, which clarifies the following twoaspects of Topic 606: (a) identifying performance obligations; and (b) the licensing implementation guidance. Further, in May 2016, the FASB issued ASUNo. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients, which provides clarifyingguidance in certain narrow areas and adds some practical expedients. The amendments do not change the core principles of the guidance in Topic 606 andare effective for the Company’s fiscal year beginning January 1, 2018. Early application is permitted only as of annual reporting periods beginning afterDecember 15, 2016, including interim reporting periods within that reporting period. The Company is currently evaluating the accounting, transition anddisclosure requirements of these standards and cannot currently estimate the financial statement impact of adoption.In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments,which is intended to reduce diversity in practice regarding how certain cash receipts and cash payments are presented and classified in the statement of cashflows. Specifically, it addresses the following eight issues: debt prepayment or debt extinguishment costs; settlement of zero-coupon debt instruments;contingent consideration payments made after a business combination; proceeds from the settlement of insurance claims; proceeds from the settlement ofcorporate-owned life insurance policies, including bank-owned life insurance policies; distributions received from equity method investments; beneficialinterests in securitization transactions; and separately identifiable cash flows and application of the predominance principle. The new guidance is effectivefor fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. The Company hasevaluated the accounting, transition and disclosure requirements of the standard and does not expect it to have a material impact on the Company’sconsolidated financial statements.The Company believes that the impact of other recently issued but not yet adopted accounting pronouncements will not have a material impact on theCompany’s consolidated financial position, results of operations, and cash flows, or do not apply to the Company’s operations.(3) Intangible AssetsIntangible assets consist of the historical acquisition cost of certain technology rights for Vascepa and have an estimated remaining useful life of 13.6 years.The carrying value as of December 31, 2016 is as follows: In thousands Gross AccumulatedAmortization Net Weighted AverageRemaining UsefulLife (in years) Technology rights $11,624 $(2,852) $8,772 13.6 F-23Table of ContentsAmortization expense for each of the years ended December 31, 2016 and 2015 was $0.6 million and is included in research and development expense.Estimated future amortization expense, based upon the Company’s intangible assets as of December 31, 2016 is as follows: In thousandsYear Ending December 31, Amount 2017 $646 2018 646 2019 646 2020 646 2021 646 Thereafter 5,542 Total $8,772 (4) InventoryThe Company capitalizes its purchases of saleable inventory of Vascepa from suppliers that have been qualified by the FDA.

F-24Table of Contents(6) Accrued Expenses and Other Current LiabilitiesAccrued expenses and other current liabilities consist of the following as of December 31, 2016 and 2015: In thousands 2016 2015 Payroll and payroll-related expenses $6,611 $5,241 Research and development expenses 293 828 Sales and marketing accruals 2,821 3,141 Accrued revenue allowances 22,195 10,732 All other 5,800 4,284 Total accrued expenses and other current liabilities $37,720 $24,226 (7) Warrants and Warrant Derivative LiabilityOn October 16, 2009, the Company completed a $70.0 million private placement with both existing and new investors resulting in $62.3 million in netproceeds and an additional $3.6 million from bridge notes converted in conjunction with the private placement. In consideration for the $62.3 million in netcash proceeds Amarin issued 66.4 million units, each unit consisting of (i) one ADS (representing one ordinary share) at a purchase price of $1.00 and (ii) awarrant with a five year term to purchase 0.5 (one half) of an ADS at an exercise price of $1.50 per ADS. In consideration for the conversion of $3.6 million ofconvertible bridge notes, Amarin issued 4.0 million units, each unit consisting of (i) one ADS (representing one ordinary share) at a purchase price of $0.90and (ii) a warrant with a five year term to purchase 0.5 (one half) of an ADS at an exercise price of $1.50 per ADS. The total number of warrants issued inconjunction with the financing was 35.2 million.In conjunction with the October 2009 financing, the Company issued an additional 0.9 million warrants to three former officers. The warrants issued inconnection with the October 2009 financing contained a pricing variability feature which provided for an increase to the exercise price if the exchange ratebetween the U.S. dollar and British pound adjusts such that the warrants could be exercised at a price less than the £0.5 par value of the common stock—thatis, if the exchange rate exceeded U.S. $3.00 per £1.0 sterling. Due to the potential variable nature of the exercise price, the warrants were not considered to beindexed to the Company’s common stock. Accordingly, the warrants did not qualify for the exception to classify the warrants within equity and wereclassified as a derivative liability.The fair value of this warrant derivative liability was remeasured at each reporting period, with changes in fair value recognized in the consolidated statementof operations. Upon exercise, the fair value of the warrants exercised was remeasured and reclassified from warrant derivative liability to additionalpaid-in-capital. Although the warrants contained a pricing variability feature, the number of warrants issuable remained fixed. Therefore, the maximumnumber of common shares issuable as a result of the October 2009 private placement was 36.1 million.In October 2014, the Company and the holders of the remaining October 2009 warrants mutually agreed to extend the expiration date of such warrants fromOctober 16, 2014 to February 27, 2015. Of the 8,087,388 warrants outstanding as of December 31, 2014, 1,844,585 warrants were exercised, resulting in netproceeds to the Company of $2.7 million, and the remaining 6,242,803 warrants expired and the related derivative liability was extinguished. As such, nowarrants were outstanding as of December 31, 2016.(8) DebtLong-Term Debt from Royalty-Bearing Instrument—December 2012 FinancingOn December 6, 2012, the Company entered into an agreement with BioPharma Secured Debt Fund II Holdings Cayman LP, or BioPharma. Under thisagreement, the Company granted to BioPharma a security interest in F-25Table of Contentsfuture receivables associated with the Vascepa patent rights, in exchange for $100.0 million received at the closing of the agreement which occurred inDecember 2012. Under these terms, the Company continues to own all Vascepa intellectual property rights, however, such rights, as described below, couldbe used by BioPharma as collateral for repayment of the remaining unpaid balance under this agreement if the Company defaults on making requiredpayments. In the agreement, the Company agreed to repay BioPharma up to $150.0 million with such repayment based on a portion of revenues andreceivables generated from Vascepa.As of December 31, 2016, the remaining amount to be repaid to BioPharma is $125.6 million. During the year ended December 31, 2016, the Company maderepayments under the agreement of $11.7 million to BioPharma and an additional $3.8 million is scheduled to be paid in February 2017 for the fourth quarterof 2016. These payments were calculated based on the threshold limitation, as described below, as opposed to the scheduled quarterly repayments.Additional quarterly repayments, subject to the threshold limitation, are scheduled to be paid.The final maximum contractual quarterly amount which could be due for payment, except upon a change of control and subject to the threshold limitation, is$13.0 million scheduled for payment in May 2017. All such payments reduce the remainder of the $150.0 million in aggregate payments to BioPharma.These quarterly payments are subject to a quarterly threshold amount whereby, if a calculated threshold, based on quarterly Vascepa revenues, is notachieved, the quarterly payment payable in that quarter can at the Company’s election be reduced, with the reduction carried forward without interest forpayment in a future period. The payment of any carried forward amount is subject to similarly calculated threshold repayment amounts based on Vasceparevenue levels. Except upon a change of control in Amarin, the agreement does not expire until $150.0 million in aggregate has been repaid. Except in theevent of the Company’s default, there is no compounding of interest and no scheduled cliff payment due under this agreement. Rather, payment will be made,subject to the threshold limitation, until $150.0 million in aggregate has been repaid, including payments made previously. The Company can prepay anamount equal to $150.0 million less any previously repaid amount.The Company currently estimates that its Vascepa revenue levels will not be high enough in each quarter to support repayment to BioPharma in accordancewith the maximum quarterly amounts in the repayment schedule. For each quarterly period since the inception of the debt, revenues were below thecontractual threshold amount such that cash payments were calculated for each period reflecting the optional reduction amount as opposed to the contractualthreshold payment due for each quarterly period. In accordance with the agreement with BioPharma, quarterly differences between the calculated optionalreduction amounts and the repayment schedule amounts are rescheduled for payment beginning in the second quarter of 2017. Any such deferred repaymentswill remain subject to continued application of the quarterly ceiling in amounts due established by the calculated threshold limitation based on quarterlyVascepa revenues. No additional interest expense or liability is incurred as a result of such deferred repayments. These estimates will be reevaluated eachreporting period by the Company and adjusted if necessary, prospectively.The Company determined the redemption feature upon a change of control to be an embedded derivative requiring bifurcation. The fair value of theembedded derivative was calculated by determining the fair value of the debt with the change in control provision included and also without the change incontrol provision. The difference between the two fair values of the debt was determined to be the fair value of the embedded derivative, and upon closingthe Company recorded a derivative liability of $14.6 million as a reduction to the note payable. The fair value of this derivative liability is remeasured ateach reporting period, with changes in fair value recognized in the consolidated statement of operations and any changes in the assumptions used inmeasuring the fair value of the derivative liability could result in a material increase or decrease in its carrying value. Based on current assumptionsunderlying the valuation, the Company recognized a $5.5 million gain on change in fair value of derivative liability during the year ended December 31,2016, as compared to a $0.7 million loss on change in fair value of derivative liability during the year ended December 31, 2015As of December 31, 2016 and 2015, the carrying value of the BioPharma debt, net of the unamortized debt discount and issuance costs, was $93.6 millionand $91.5 million, respectively. During the year ended F-26Table of ContentsDecember 31, 2016, the Company recorded cash and non-cash interest expense of $6.7 million and $2.1 million, respectively, in connection with theBioPharma debt. During the year ended December 31, 2015, the Company recorded $6.6 million and $1.9 million of cash and non-cash interest expense,respectively, in connection with BioPharma debt. The Company will periodically evaluate the remaining term of the agreement and the effective interest rateis recalculated each period based on the Company’s most current estimate of repayment.To secure the obligations under the agreement with BioPharma, the Company granted BioPharma a security interest in the Company’s patents, trademarks,trade names, domain names, copyrights, know-how and regulatory approvals related to the covered products, all books and records relating to the foregoingand all proceeds of the foregoing, referred to collectively as the collateral. If the Company (i) fails to deliver a payment when due and does not remedy thatfailure within a specific notice period, (ii) fails to maintain a first-priority perfected security interest in the collateral in the United States and does not remedythat failure after receiving notice of such failure or (iii) becomes subject to an event of bankruptcy, then BioPharma may attempt to collect the maximumamount payable by the Company under this agreement (after deducting any payments the Company has already made).Under the Purchase and Sale Agreement with BioPharma, the Company is restricted from paying dividends on its common shares, unless it has cash and cashequivalents in excess of a specified amount after such payment.January 2012 Exchangeable Senior NotesIn January 2012, the Company issued $150.0 million in principal amount of 3.5% Exchangeable Senior Notes due 2032 (the “2012 Notes”), a portion ofwhich was subsequently exchanged and a portion of which was extinguished (see discussion of May 2014 and November 2015 Exchangeable Senior Notesbelow), such that $15.1 million in principal amount remains outstanding as of December 31, 2016. In January 2017, holders of the 2012 Notes exercised theiroption to put the 2012 Notes to the Company. As a result, the Company repurchased approximately $15.0 million in aggregate principal amount of 2012Notes, such that $0.1 million in principal amount of 2012 Notes currently remains outstanding. Also in January 2017, in contemplation of this surrender of2012 Notes for repurchase, the Company and its wholly owned subsidiary, Corsicanto II Designated Activity Company (“Corsicanto II”) entered intoseparate, privately negotiated purchase agreements with certain investors pursuant to which Corsicanto II issued and sold $30.0 million in aggregateprincipal amount of 3.5% Exchangeable Senior Notes due 2047 (the “2017 Notes”). The Company has initiated the process to redeem the remaining$0.1 million of 2012 Notes, which is expected to be completed in the first quarter of 2017. See Note 18—Subsequent Events for further discussion of theissuance of the 2017 Notes.The 2012 Notes were issued by Corsicanto Limited, an Irish limited company acquired by Amarin in January 2012. Corsicanto Limited is a wholly-ownedsubsidiary of Amarin. The general, unsecured, senior obligations are fully and unconditionally guaranteed by Amarin but not by any of the Company’s othersubsidiaries. Corsicanto Limited has no assets, operations, revenues or cash flows other than those related to the issuance, administration and repayment ofthe 2012 Notes and 2014 Notes. There are no significant restrictions on the ability of Amarin to obtain funds from Corsicanto Limited in the form of cashdividends, loans, or advances. Net proceeds to the Company, after payment of underwriting fees and expenses, were approximately $144.3 million.The 2012 Notes have a stated interest rate of 3.5% per year, payable semiannually in arrears on January 15 and July 15 of each year beginning on July 15,2012, and ending upon the 2012 Notes’ maturity on January 15, 2032. The 2012 Notes are subject to repurchase in cash by the Company at the option of theholders on each of January 19, 2017, January 19, 2022, and January 19, 2027, at a price equal to 100% of the principal amount of the 2012 Notes to berepurchased, plus accrued and unpaid interest to, but excluding, the repurchase date. The 2012 Notes are exchangeable under certain circumstances into cash,ADSs, or a combination of cash and ADSs, at the Company’s election, with an initial exchange rate of 113.4752 ADSs per $1,000 principal amount of 2012Notes (equivalent to an initial exchange price of approximately $8.8125 per ADS), subject to adjustment in certain circumstances, including adjustment ifthe Company pays cash dividends. If the Company elected physical settlement, the net remaining outstanding portion of the 2012 Notes would beexchangeable into F-27Table of Contents1,714,270 ADSs. Based on the closing price of the Company’s stock as of December 31, 2016, the principal amount of the 2012 Notes would exceed thevalue of the shares if converted on that date by $9.8 million.Additional covenants include: (i) limitations on future indebtedness under certain circumstances, (ii) the timely filing of documents and reports pursuant toSection 13 or 15(d) of the Securities Exchange Act of 1934 with both the SEC and the Trustee and (iii) maintaining the tradability of the 2012 Notes. TheCompany is required to use commercially reasonable efforts to maintain the listing of the 2012 Notes on the Global Exchange Market operated under thesupervision of the Irish Stock Exchange (or other recognized stock exchange as defined in the 2012 Notes indenture). If the 2012 Notes are not freelytradable, as a result of restrictions pursuant to U.S. securities law or the terms of the 2012 Notes indenture or the 2012 Notes, the Company shall payadditional interest on the 2012 Notes at the rate of 0.50% per annum of the principal amount of 2012 Notes outstanding for each day during such period forwhich the Company’s failure to file has occurred and is continuing or for which the 2012 Notes are not freely tradable.The Company may not redeem the 2012 Notes prior to January 19, 2017, other than in connection with certain changes in the tax law of a relevant taxingjurisdiction that results in additional amounts becoming due with respect to payments and/or deliveries on the 2012 Notes. On or after January 19, 2017 andprior to the maturity date, the Company may redeem for cash all or part of the 2012 Notes at a redemption price equal to 100% of the principal amount of the2012 Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. There is no prepayment penalty or sinking fundprovided for the 2012 Notes. If the Company undergoes a change in control, holders may require the Company to repurchase for cash all or part of their 2012Notes at a repurchase price equal to 100% of the principal amount of the 2012 Notes to be repurchased, plus accrued and unpaid interest to, but excluding,the change in control repurchase date. The 2012 Notes are the Company’s senior unsecured obligations and rank senior in right of payment to the Company’sfuture indebtedness that is expressly subordinated in right of payment to the 2012 Notes and equal in right of payment to the Company’s future unsecuredindebtedness that is not so subordinated. The 2012 Notes are effectively junior in right of payment to future secured indebtedness to the extent of the valueof the assets securing such indebtedness.The 2012 Notes are exchangeable under certain circumstances. At the time of issuance, the Company calculated the fair value of the liability component ofthe outstanding 2012 Notes to be $126.2 million, and the excess of the principal amount of the debt over the liability component of $23.8 million wasallocated to the conversion option resulting in a discount on the debt and corresponding increase in equity as a result of the cash settlement feature. Thediscount created from allocating proceeds to the conversion option was amortized to interest expense using the effective interest method over the 2012Notes’ estimated remaining life, which was calculated to be a period of twenty-four months. As of both December 31, 2016 and 2015, the discount createdfrom the allocation of the proceeds to the conversion option was fully amortized and the carrying amount of the conversion option was $11.5 million. Theconversion option will not be subsequently remeasured as long as it continues to meet the criteria for equity classification.The Company also recorded a debt discount to reflect the value of the underwriter’s discounts and offering costs. A portion of the debt discount fromunderwriter’s discounts and offering costs was allocated to the equity and liability components of the 2012 Notes in proportion to the proceeds allocated toeach component. The portion of the debt discount from underwriter’s discounts and offering costs allocated to the liability component was amortized asinterest expense over the estimated life of the 2012 Notes of twenty-four months. As of both December 31, 2016 and 2015, the debt discount was fullyamortized and the carrying value of the 2012 Notes was $15.1 million after an exchange and repayment of a portion of the 2012 Notes (see below for furtherdiscussion of the May 2014 Notes and November 2015 Notes). The outstanding 2012 Notes may be put to the Company (at the holders’ option, uponfundamental change or an event of default), or converted by holders and the holders have the option to put the 2012 Notes back to the Company on each ofJanuary 19, 2017, 2022 and 2027 for cash equal to 100% of the principal amount plus accrued and unpaid interest. As a result, the carrying value of the 2012Notes of $15.1 million is classified as a current liability as of December 31, 2016. During the F-28Table of Contentsyears ended December 31, 2016 and 2015, the Company recognized contractual coupon interest expense of $0.5 million and $1.0 million, respectively,related to the 2012 Notes. The Company made the contractual interest payments due on the 2012 Notes during the years ended December 31, 2016 and 2015of $0.5 million and $1.3 million, respectively, and had accrued interest of $0.2 million and $0.3 million as of December 31, 2016 and 2015, respectively,which is included in current portion of exchangeable senior notes, net of discount.May 2014 Exchangeable Senior NotesIn May 2014, the Company entered into separate, privately negotiated exchange agreements with certain holders of the 2012 Notes pursuant to whichCorsicanto exchanged $118.7 million in aggregate principal amount of the existing 2012 Notes for $118.7 million in aggregate principal amount of new3.5% May 2014 Exchangeable Senior Notes due 2032 (the “2014 Notes”), following which $31.3 million in aggregate principal amount of the 2012 Notesremained outstanding with terms unchanged (the 2012 Notes and 2014 Notes are referred to collectively as the “Notes”). In September 2016, Corsicantomandatorily exchanged $118.7 million of aggregate principal amount of the 2014 Notes for equity upon satisfaction of specified equity conditions asdescribed below, such that no 2014 Notes remained outstanding as of December 31, 2016.The 2014 Notes indenture contained a provision that allowed the Company to elect at its option to cause all or any portion of the 2014 Notes to bemandatorily exchanged in whole or in part at any time prior to the close of business on the business day preceding January 15, 2032 if the Daily VWAP (asdefined in the 2014 Notes indenture) equaled or exceeded 110% of the Exchange Price then in effect for at least 20 VWAP Trading Days (as defined in the2014 Notes indenture) in any 30 VWAP Trading Day period and upon satisfaction of other specified equity conditions, including that the ADSs issuableupon exchange of the 2014 Notes be eligible for resale without registration by non-affiliates and listed on The NASDAQ Global Market, its related exchangesor the New York Stock Exchange. In August 2016, Corsicanto gave notice to the holders of the 2014 Notes that the above described conditions had beensatisfied and exercised its option to mandatorily exchange $118.7 million of aggregate principal amount of the 2014 Notes for equity with settlement inSeptember 2016, such that all of the outstanding 2014 Notes were retired. In the event of physical settlement, the 2014 Notes were initially exchangeableinto 45,666,925 ADSs. The initial exchange rate was 384.6154 ADSs per $1,000 principal amount of the 2014 Notes (equivalent to an initial exchange priceof approximately $2.60 per ADS, or the Exchange Price), subject to adjustment in certain circumstances, including, but not limited to, the payment of cashdividends or the Company’s exercise of its optional exchange rights. Consistent with the 2014 Notes indenture, the final as-adjusted exchange rate was402.0746 ADSs per $1,000 of principal amount, resulting in 47,739,925 ADSs being issued in exchange for the 2014 Notes. Refer to the end of this Note fordiscussion of the accounting treatment for this transaction.The 2014 Notes had a stated interest rate of 3.5% per year, payable semiannually in arrears on January 15 and July 15 of each year beginning on July 15,2014, and ending upon the 2014 Notes’ maturity on January 15, 2032, had the notes not been exchanged early. The 2014 Notes indenture provided holdersthe option to exchange the 2014 Notes at any time after the issuance of the 2014 Notes and prior to the close of business on the second business dayimmediately preceding January 15, 2032. If a fundamental change (as defined in the 2014 Notes indenture) had occurred prior to the 2014 Notes beingexchanged, holders may have required the Company to repurchase all or part of their 2014 Notes for cash at a fundamental change repurchase price equal to100% of the aggregate principal amount of the 2014 Notes to be repurchased, plus accrued and unpaid interest to, but not including, the fundamental changerepurchase date. In addition, holders of the 2014 Notes may have required the Company to repurchase all or any portion of the 2014 Notes on each ofJanuary 19, 2019, January 19, 2024 and January 19, 2029 for cash at a price equal to 100% of the aggregate principal amount of the 2014 Notes to berepurchased, plus accrued and unpaid interest to, but not including, the repurchase date.As a result of the note exchange in 2014 (as described above), the Company assessed both quantitative and qualitative aspects of the features of the 2014Notes as compared to the 2012 Notes. Such assessment resulted in the conclusion that the features of the 2014 Notes represented a substantive modificationfrom the 2012 Notes as F-29Table of Contentsthe terms of the exchange resulted in a substantive modification to the embedded conversion feature within the 2012 Notes, and as such should be accountedfor as an extinguishment of debt. In accordance with ASC 470-20, the Company extinguished the 2012 Notes by recording a gain on extinguishment of theliability component of $38.0 million and repurchase of the conversion option in equity through a reduction to additional paid-in capital of $10.1 million.The 2014 Notes were recorded at fair value of $90.8 million representing a $27.9 million discount to par. In addition the Company recognized $2.5 millionin underwriter’s fees and offering costs and initially classified those costs as deferred assets. Effective January 2016, the Company adopted ASU No. 2015-03,Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs, which requires that debt issuance costs related to arecognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with the treatmentof debt discounts. As the standard is required to be adopted on a retrospective basis, the Company reclassified $1.8 million of underwriters’ fees and offeringcosts related to the 2014 Notes from other long-term assets to exchangeable senior notes, net of discount, within the consolidated balance sheet as ofDecember 31, 2015.The Company further allocated $3.5 million of the $90.8 million fair value of the 2014 Notes to the derivative liability related to the fundamental changeredemption feature (as described above). The fair value of this derivative liability was remeasured at each reporting period, with changes in fair valuerecognized in the consolidated statement of operations As a result of the mandatory exchange of the debt host, the Company derecognized the relatedderivative liability and recognized a $2.1 million gain on change in fair value of derivative liability in the year ended December 31, 2016, as compared to a$0.5 million gain on change in fair value of derivative liability recognized in the year ended December 31, 2015.Because the conversion option in the 2014 Notes received an exception from derivative accounting and only required gross physical settlement in shares, theembedded option did not require separate accounting and was therefore accounted for as part of the debt host at amortized cost. The debt discount wasamortized as interest expense over the estimated life of the 2014 Notes and was recognized in the consolidated statement of operations as interest expense. Asof December 31, 2016 and 2015, the carrying value of the 2014 Notes, net of the unamortized debt discount and issuance costs, was nil and $94.6 million,respectively. During the year ended December 31, 2016, the Company recognized aggregate interest expense of $7.7 million related to the 2014 Notes, ofwhich $4.8 million represents non-cash interest and $2.9 million represents contractual coupon interest. During the year ended December 31, 2015, theCompany recognized aggregate interest expense of $10.4 million related to the 2014 Notes, of which $6.2 million represents non-cash interest and$4.2 million represents contractual coupon interest. The Company made the contractual interest payments due on the 2014 Notes during the years endedDecember 31, 2016 and 2015 of $4.2 million in each period, and had accrued interest of nil and $1.9 million as of December 31, 2016 and 2015, respectively,which is included in current portion of exchangeable senior notes, net of discount.November 2015 Exchangeable Senior NotesIn November 2015, the Company entered into a privately negotiated subscription agreement with one of its existing investors (the “Investor”), pursuant towhich the Investor agreed to purchase approximately $31.3 million in aggregate principal amount of new 3.5% November 2015 Exchangeable Senior Notesdue 2032 (the “2015 Notes”) for approximately $27.5 million. Approximately $15.9 million of such proceeds were used to finance the repayment of a portionof the 2012 Notes with the remainder to be used for working capital and general corporate purposes. The 2015 Notes were issued by Amarin Corporation plcand were not guaranteed by any entity, but otherwise had substantially identical terms to the 2014 Notes, including the provision related to the Company’soptional exchange rights. In August 2016, the Company gave notice to the holders of the 2015 Notes that the Daily VWAP conditions as described above forthe 2014 Notes had been satisfied and exercised its option to mandatorily exchange $31.3 million of aggregate principal amount of the 2015 Notes for equitywith settlement in September 2016, such that all of the outstanding 2015 Notes were retired. In the event of physical settlement, the 2015 Notes were initiallyexchangeable into 12,025,385 ADSs. The initial exchange rate was 384.6154 ADSs per $1,000 principal amount of 2015 Notes (equivalent to an initialexchange price of F-30Table of Contentsapproximately $2.60 per ADS), subject to adjustment in certain circumstances, including, but not limited to, the payment of cash dividends or the Company’sexercise of optional exchange rights. Consistent with the terms of the 2015 Notes, the final as-adjusted exchange rate was 402.0746 ADSs per $1,000 ofprincipal amount, resulting in 12,571,263 ADSs being issued in exchange for the 2015 Notes. Refer to the end of this Note for discussion of the accountingtreatment for this transaction.The 2015 Notes were recorded at fair value of $27.5 million representing a $3.8 million discount to par. In addition, the Company recognized $0.1 million inoffering costs and initially classified those costs as deferred assets. As described for the 2014 Notes above, effective January 2016, the Company adoptedASU No. 2015-03, Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. As the standard is required to beadopted on a retrospective basis, the Company reclassified $0.1 million of underwriters’ fees and offering costs related to the 2015 Notes from other long-term assets to exchangeable senior notes, net of discount, within the consolidated balance sheet as of December 31, 2015.The Company further allocated $0.5 million of the $27.5 million fair value of the 2015 Notes to the derivative liability related to the fundamental changeredemption feature (as described under the 2014 Notes above). The fair value of this derivative liability was remeasured at each reporting period, withchanges in fair value recognized in the consolidated statement of operations. As a result of the mandatory exchange of the debt host, the Companyderecognized the related derivative liability and recognized a $0.6 million gain on change in fair value of derivative liability in the year ended December 31,2016, as compared to a $0.1 million loss on change in fair value of derivative liability recognized in the year ended December 31, 2015.Because the conversion option in the 2015 Notes received an exception from derivative accounting and only required gross physical settlement in shares, theembedded option did not require separate accounting and was therefore accounted for as part of the debt host at amortized cost. The debt discount wasamortized as interest expense over the estimated life of the 2015 Notes and recognized in the consolidated statement of operations as interest expense. As ofDecember 31, 2016 and 2015, the carrying value of the 2015 Notes, net of the unamortized debt discount and issuance costs, was nil and $27.0 million,respectively. During the year ended December 31, 2016, the Company recognized aggregate interest expense of $1.7 million related to the 2015 Notes, ofwhich $0.9 million represents non-cash interest and $0.8 million represents contractual coupon interest. During the year ended December 31, 2015, theCompany recognized aggregate interest expense of $0.2 million related to the 2015 Notes, of which $0.1 million represents non-cash interest and$0.1 million represents contractual coupon interest. The Company made the contractual interest payments due on the 2015 Notes during the year endedDecember 31, 2016 of $0.7 million, and had accrued interest of nil and $0.1 million as of December 31, 2016 and 2015, respectively, which is included incurrent portion of exchangeable senior notes, net of discountConcurrent with the issuance of the 2015 Notes, Corsicanto Limited and the Company entered into separate, privately negotiated purchase agreements withcertain holders of the 2012 Notes pursuant to which the Company purchased (the “2012 Notes Purchase”) approximately $16.2 million in aggregate principalamount of the 2012 Notes for $15.9 million, which included accrued but unpaid interest on such 2012 Notes. The 2012 Notes Purchase was funded by theissuance of the 2015 Notes. Following the closing of the 2012 Notes Purchase, Corsicanto had approximately $15.1 million in aggregate principal amount of2012 Notes outstanding. The 2012 Notes Purchase was accounted for as an extinguishment of debt and the Company recorded a gain of $1.3 million uponextinguishment during the fourth quarter of 2015, which represents the reacquisition of the conversion option at fair value and a negotiated discount on thepurchase of the notes partially offset by legal and transaction advisory costs incurred.As described in the May 2014 Exchangeable Senior Notes and November 2015 Exchangeable Senior Notes sections above, the Company mandatorilyexchanged, in total, $150.0 million in aggregate principal amount ($127.3 million in carrying value, net of unamortized debt discount and issuance costs) ofoutstanding 2014 Notes and 2015 Notes resulting in the issuance of 60,311,188 ADSs and recognition of $40.1 million in common F-31Table of Contentsstock and $87.4 million in additional paid-in capital during the year ended December 31, 2016. Included within this $87.4 million is $0.8 million of accruedbut unpaid interest as of the exchange date deemed satisfied and discharged in full upon delivery of the ADSs consistent with the terms of the notes and ASC470-20, less $0.7 million of transaction costs.(9) Commitments and ContingenciesLitigationIn September and October 2016, the Company received paragraph IV certification notices from four companies contending to varying degrees that certain ofits patents are invalid, unenforceable and/or will not be infringed by the manufacture, use, sale or offer for sale of a generic form of Vascepa as described inthose companies’ abbreviated new drug applications, or ANDAs. The Company filed patent infringement lawsuits against three of these four ANDAapplicants. In October 2016, Amarin filed a lawsuit against Roxane Laboratories, Inc. and related parties (collectively, “Roxane”) in the U.S. District Courtfor the District of Nevada. The case against Roxane is captioned Amarin Pharma, Inc. et al. v. Roxane Laboratories, Inc. et al., Civ. A. No. 2:16-cv-02525 (D.Nev.). In November 2016, Amarin filed a lawsuit against Dr. Reddy’s Laboratories, Inc. and Dr. Reddy’s Laboratories, Ltd. (collectively, “DRL”) in the U.S.District Court for the District of Nevada. The case against DRL is captioned Amarin Pharma, Inc. et al. v. Dr. Reddy’s Laboratories, Inc. et al., Civ. A. No.2:16-cv-02562 (D. Nev.). In November 2016, Amarin filed a lawsuit against Teva Pharmaceuticals USA, Inc. and Teva Pharmaceuticals Industries Limited(collectively, “Teva”) in the U.S. District Court for the District of Nevada. The case against Teva is captioned Amarin Pharma, Inc. et al. v. TevaPharmaceuticals USA, Inc. et al., Civ. A. No. 2:16-cv-02658. In all three lawsuits, Amarin is seeking, among other remedies, an order enjoining eachdefendant from marketing generic versions of Vascepa before the last to expire of the asserted patents in 2030. The three lawsuits have been consolidated forpretrial proceedings, and are in their early stages. As a result of the statutory stay associated with the filing of these lawsuits under the Hatch-Waxman Act, theFDA cannot grant final approval to Roxane, DRL, or Teva’s respective ANDA before January 2020, unless there is an earlier court decision holding that thesubject patents are not infringed and/or are invalid.The fourth ANDA applicant referenced above is Apotex Inc. (“Apotex”), which sent Amarin a paragraph IV certification notice in September 2016. The noticereflected that Apotex made a paragraph IV notice as to some, but not all, of the patents listed in the Orange Book for Vascepa. Because Apotex did not make aparagraph IV certification as to all listed patents, Apotex cannot market a generic version of Vascepa before the last to expire of the patents for which Apotexdid not make a paragraph IV certification, which is in 2030. At a later date, Apotex may elect to amend its ANDA in order to make a paragraph IV certificationas to additional listed patents. If and when Apotex does make such an amendment, it would be required to send Amarin an additional paragraph IVcertification notice, and Amarin would then have the ability to file a lawsuit against Apotex pursuant to the Hatch-Waxman Act.The Company intends to vigorously enforce its intellectual property rights relating to Vascepa, but cannot predict the outcome of the Roxane, DRL or Tevalawsuits or any subsequently filed lawsuits.On April 26, 2016, the U.S. District Court for the District of New Jersey granted the Company’s motion to dismiss the putative consolidated class actionlawsuit captioned In re Amarin Corporation plc, Securities Litigation, No. 3:13-cv-06663 (D.N.J. Nov. 1, 2013). The class action was dismissed withoutprejudice with leave for plaintiffs to file an amended complaint. The lawsuit seeks unspecified monetary damages and attorneys’ fees and costs alleging thatthe Company and certain of its current and former officers and directors made misstatements and omissions regarding the FDA’s willingness to approveVascepa’s ANCHOR indication and related contributing factors and the potential relevance of data from the ongoing REDUCE-IT trial to that potentialapproval. The April 2016 dismissal was the second motion to dismiss granted in favor of Amarin and related defendants in this litigation. The first motion todismiss in this litigation was granted in June 2015 in response to the original complaint and related amendment. F-32Table of ContentsOn May 24, 2016, plaintiffs notified the court that they would not file another amended complaint and, on May 26, 2016, filed a notice of appeal of the mostrecent dismissal to the Third Circuit Court of Appeals. Plaintiffs filed their appellate brief on September 21, 2016, the Company filed an opposition brief onNovember 29, 2016, and plaintiffs filed their reply on December 29, 2016. No hearing date has been set. The Company plans a vigorous defense to thisappeal. The Company has insurance coverage that is anticipated to cover any significant loss exposure that may arise from this action.In addition to the above, in the ordinary course of business, the Company is from time to time involved in lawsuits, claims, investigations, proceedings, andthreats of litigation relating to intellectual property, commercial arrangements and other matters.LeasesThe Company leases office space under operating leases. Future minimum lease payments under these leases, net of sublease rental income, as ofDecember 31, 2016 are as follows: In thousandsYear Ending December 31, Operating 2017 $528 2018 126 2019-2021 — Total $654 On September 30, 2011, the Company entered into an agreement for 320 square feet of office space at 2 Pembroke House, Upper Pembroke Street 28-32 inDublin, Ireland.

Certain supply agreements requireannual minimum volume commitments by the Company and certain volume shortfalls may require payments for such shortfalls, as detailed below.The Company entered into its initial Vascepa API supply agreement with Nisshin Pharma, Inc (“Nisshin”) in 2010. In 2011, the Company entered intoagreements with two additional suppliers, Chemport, Inc (“Chemport”) F-33Table of Contentsand BASF (formerly Equateq Limited), for the supply of API. In 2012, the Company agreed to terms with a fourth API supplier, a consortium of companies ledby Slanmhor Pharmaceutical, Inc. (“Slanmhor”). The API supply agreement with BASF terminated in February 2014. In July 2014, the Company terminatedthe supply agreement with Slanmhor and subsequently, in June 2015, entered into a new supply agreement with Finorga SAS (“Novasep”). These agreementsincluded requirements for the suppliers to meet certain product specifications and qualify their materials and facilities with applicable regulatory authoritiesincluding the FDA. The Company has incurred certain costs associated with the qualification of product produced by these suppliers as described below.Nisshin, Chemport and Novasep are currently the three manufacturers from which the Company purchases API. As of December 31, 2016, the Company hasno royalty, milestone or minimum purchase commitments with Nisshin.Chemport was approved by the FDA to manufacture API for commercial sale in April 2013 and the Company began purchasing commercial supply fromChemport in 2013. The agreement with Chemport contains a provision requiring the Company to pay Chemport in cash for any shortfall in the minimumpurchase obligations. The Company began purchasing commercial supply from Novasep in 2015. API manufactured by Novasep was previously approved bythe FDA in July 2014. The 2015 supply agreement with Novasep contains a provision requiring the Company to pay Novasep a cash remedy for any shortfallin the minimum purchase obligations.Pursuant to the supply agreements, there is a total of $44.6 million that is potentially payable over the term of such agreements based on minimum purchaseobligations. The Company continues to meet its contractual purchase obligations.Under the 2004 share repurchase agreement with Laxdale Limited (“Laxdale”), upon receipt of marketing approval in Europe for the first indication forVascepa (or first indication of any product containing Amarin Neuroscience Limited intellectual property acquired from Laxdale in 2004), the Companymust make an aggregate stock or cash payment to the former shareholders of Laxdale (at the sole option of each of the sellers) of £7.5 million (approximately$9.3 million as of December 31, 2016). Also under the Laxdale agreement, upon receipt of a marketing approval in the United States or Europe for a furtherindication of Vascepa (or further indication of any other product using Amarin Neuroscience Limited intellectual property), the Company must make anaggregate stock or cash payment (at the sole option of each of the sellers) of £5 million (approximately $6.2 million as of December 31, 2016) for each of thetwo potential market approvals (i.e., £10 million maximum, or approximately $12.3 million as of December 31, 2016).The Company has no provision for any of the obligations above since the amounts are either not probable or able to be estimated as of December 31, 2016.(10) EquityPreferred StockOn March 5, 2015, the Company entered into a subscription agreement with four institutional investors (the “Purchasers”), including both existing and newinvestors, for the private placement of 352,150,790 restricted American Depositary Shares, each representing one (1) share of Amarin’s Series A ConvertiblePreference Shares, par value £0.05 per share, in the capital of the Company (“Series A Preference Shares”), resulting in gross proceeds to the Company of$52.8 million. The closing of the private placement occurred on March 30, 2015.For each restricted American Depositary Share, the Purchasers paid a negotiated price of $0.15 (equating to $1.50 on an as-if-converted-to-ordinary-sharesbasis), resulting in $52.8 million in aggregate gross proceeds to the Company, before deducting estimated offering expenses of approximately $0.7 million.The net proceeds are reflected as preferred stock in the accompanying consolidated balance sheets. F-34Table of ContentsEach ten (10) Series A Preference Shares may be consolidated and redesignated as one (1) ordinary share, par value £0.50 per share, in the capital of theCompany, each ordinary share to be represented by American Depositary Shares (“ADSs”), provided that consolidation will be prohibited if, as a result, theholder of such Series A Preference Shares and its affiliates would beneficially own more than 4.99% of the total number of Amarin ordinary shares or ADSsoutstanding following such redesignation (the “Beneficial Ownership Limitation”). By written notice to the Company, a holder may from time to timeincrease or decrease the Beneficial Ownership Limitation to any other percentage not in excess of 19.9% specified in such notice; provided that any suchincrease will not be effective until the sixty-first (61st) day after such notice is delivered to the Company. This consolidation and redesignation may beeffected by a holder of Series A Preference Shares following the first to occur of the resale of the ADSs representing the ordinary shares being registered forresale under the Securities Act pursuant to an effective registration statement, following any sale of the ADSs representing the ordinary shares pursuant toRule 144 under the Securities Act, or if such ADSs representing the ordinary shares are eligible for sale under Rule 144, following the expiration of theone-year holding requirement under Rule 144. During the year ended December 31, 2015, at the request of the holders, a portion of the Series A PreferenceShares were consolidated and redesignated, resulting in the issuance of 6,283,333 ADSs such that a maximum of 32,818,464 ordinary shares remain issuableupon future consolidation and redesignation of the remaining Series A Preference Shares as of December 31, 2016, inclusive of the shares issued in July 2015as discussed below, subject to certain adjustments for dilutive events.Except as otherwise provided in the Series A Preference Share Terms or as required by applicable law, the Series A Preference Shares have no voting rights.However, as long as any Series A Preference Shares are outstanding, the Company cannot, without the approval of the holders of seventy-five percent(75%) of the then outstanding Series A Preference Shares, alter or change adversely the powers, preferences or rights attaching to the Series A PreferenceShares or enter into any agreement with respect to the foregoing.Holders of the Series A Preference Shares are entitled to receive, and the Company is required to pay, dividends (other than dividends in the form of ordinaryshares) on the Series A Preference Shares equal (on an as-if-converted-to-ordinary-shares basis) to and in the same form as dividends (other than dividends inthe form of ordinary shares) actually paid on ordinary shares when, as and if such dividends (other than dividends in the form of ordinary shares) are paid onthe ordinary shares.The restricted American Depositary Shares and Series A Preference Shares were sold in a transaction exempt from the registration requirements under theSecurities Act of 1933, as amended (the “Securities Act”) The Company filed a registration statement with the SEC covering the resale of the restrictedAmerican Depositary Shares and the ADSs representing ordinary shares created by the consolidation and redesignation of the Series A Preference Shares (the“Registrable Securities”) on April 9, 2015, which was declared effective by the SEC on May 1, 2015. In addition, the Company agreed to use itscommercially reasonable best efforts to keep the registration, and any qualification, exemption or compliance under state securities laws which the Companydetermines to obtain, continuously effective, and to keep the Registration Statement free of any material misstatements or omissions, until the earlier of(a) March 11, 2017 or (b) the date on which all Registrable Securities held by Purchasers may be sold or transferred in compliance with Rule 144 under theSecurities Act, without any volume or manner of sale restrictions.The Series A Preference Shares contain a contingent beneficial conversion feature (“BCF”) because they contain a conversion feature at a fixed rate that wasin-the-money when issued. The BCF was recorded in the three months ended June 30, 2015 as a result of the related Form S-3 Registration Statement beingdeclared effective, which represents the resolution of the contingency to convert the Series A Preference Shares. The BCF was recognized in stockholders’deficit and was measured by allocating a portion of the proceeds equal to the intrinsic value of that feature to additional paid-in capital. The effectivepurchase price of the ordinary shares into which the preferred shares are convertible was $1.50, which was used to compute the intrinsic value. The intrinsicvalue was calculated as the difference between the effective purchase price of the ordinary shares and the market value ($2.39 per share) on the date thepreferred shares were issued, multiplied by the number of F-35Table of Contentsshares into which the preferred shares are convertible. The BCF resulting from the issuance of the Series A Preference Shares was determined to be$31.3 million. The BCF was recorded as a non-cash dividend to preferred shareholders through accumulated deficit, and was therefore reflected as anadjustment to net loss applicable to common shareholders for earnings per common share purposes in accordance with GAAP for the year endedDecember 31, 2015.On March 30, 2015, in connection with the closing of the private placement, and pursuant to a pre-existing contractual right to participate in certain privateplacement transactions effected by the Company, the Company entered into a separate subscription agreement with an existing investor, Sofinnova VenturePartners VII L.P. (Sofinnova), for the purchase of an additional $5.8 million of restricted American Depositary Shares, each representing one (1) share of theCompany’s Series A Preference Shares, at the same price per share and otherwise on substantially the same terms as the initial private placement (the “SecondPrivate Placement”). In accordance with applicable marketplace rules of the NASDAQ Stock Market, the consummation of the Second Private Placement wasconditioned upon approval by the Company’s shareholders at a future meeting of the Company’s shareholders. Such approval was received at the Company’sAnnual General Meeting of Shareholders on July 6, 2015 and as a result, the closing of the Second Private Placement occurred on July 10, 2015. TheCompany issued 38,867,180 restricted ADSs, each representing one Series A Preference Share, which may be consolidated and redesignated from time to timeup to a maximum of 3,886,718 ordinary shares, each ordinary share to be represented by one ADS. For each restricted ADS, Sofinnova paid a negotiated priceof $0.15 (equating to $1.50 on an as-if-converted-to-ordinary-shares basis) resulting in gross proceeds to the Company of $5.8 million. At the time of thetransaction, Dr. James Healy was a member of the Company’s Board and a managing general partner of Sofinnova Management VII, L.L.C., which is thegeneral partner of Sofinnova. Dr. Healy resigned as Director of the Company’s Board effective December 20, 2016.The Company filed another registration statement with the SEC covering the resale of these restricted American Depositary Shares and the ADSs representingordinary shares created by the consolidation and redesignation of the Series A Preference Shares (the “Sofinnova Registrable Securities”) on July 24, 2015,which was declared effective by the SEC on August 7, 2015. In addition, the Company agreed to use its commercially reasonable best efforts to keep theregistration, and any qualification, exemption or compliance under state securities laws which the Company determines to obtain, continuously effective,and to keep the registration statement free of any material misstatements or omissions, until the earlier of (a) July 10, 2017 or (b) the date on which allSofinnova Registrable Securities held by Sofinnova may be sold or transferred in compliance with Rule 144 under the Securities Act, without any volume ormanner of sale restrictions.The existence of this preferred stock purchase option was determined to be a derivative liability effective March 5, 2015, the date on which the privateplacement was initially subscribed. The fair value of this liability was calculated using a Black-Scholes model and was determined to be $0.9 million atinception and was charged to accumulated deficit as a deemed non-cash dividend to Sofinnova. The liability was then marked to fair value as of March 30,2015, the date on which the Company executed a subscription agreement with Sofinnova, resulting in a charge of $0.9 million through gain (loss) on changein fair value of derivatives. The liability of $1.8 million was reclassified to permanent equity (additional paid-in capital) on such date. Subsequent toapproval of the Second Private Placement at the Company’s Annual General Meeting of Shareholders in July 2015, the Company recorded the remainingvalue of the BCF related to this share issuance as a non-cash dividend to preferred shareholders through accumulated deficit. The value of the BCF wasdetermined on the same basis as the first private placement and amounted to $3.4 million less $1.8 million previously recorded for the preferred stockpurchase option for a net non-cash charge of $1.6 million in the year ended December 31, 2015.Common StockIn September 2016, the Company mandatorily exchanged $118.7 million and $31.3 million of aggregate principal amount of the 2014 Notes and 2015Notes, respectively, resulting in the issuance of 47,739,925 ADSs and 12,571,263 ADSs, respectively, with each ADS representing one ordinary share of theCompany (see Note 8—Debt). F-36Table of ContentsIn August 2016, the Company completed a public offering of 21,100,000 ADSs, with each ADS representing one ordinary share of the Company. Amarin alsogranted the underwriters a 30-day option to purchase an additional 3,165,000 ADSs at the same price, which was exercised in full. The underwriterspurchased the ADSs from the Company at a price of $2.679 per ADS after commission, resulting in net proceeds to the Company of approximately$64.6 million, after deducting estimated offering expenses payable by the Company. The Company currently intends to use the net proceeds from theoffering to advance its REDUCE-IT cardiovascular outcomes trial and for general corporate and working capital purposes.Incentive Equity AwardsIn March 2016, the FASB issued ASU No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based PaymentAccounting. The Company early adopted this standard during the quarter ended June 30, 2016, without electing to change its existing accounting policy ofaccounting for forfeitures based on expected vesting. The new standard requires that excess tax benefits and deficiencies that arise upon vesting or exercise ofshare-based payments be recognized as an income tax benefit and expense in the income statement, and also that historical excess tax benefits that were notpreviously recognized because the related tax deduction had not reduced current taxes payable should be recognized on a modified retrospective basis as acumulative-effect adjustment to retained earnings as of the beginning of the annual period of adoption. Further, the new standard amends the presentation ofemployee share-based payment-related items in the statement of cash flows by requiring that: (i) excess income tax benefits and deficiencies be classified incash flows from operating activities, and (ii) cash paid to taxing authorities arising from the withholding of shares from employees be classified as cash flowsfrom financing activities. Refer to Note 2—Significant Accounting Policies above for additional discussion on the Company’s adoption of the new standard.In June 2014, the FASB issued guidance for accounting for share-based payments when the terms of an award provide that a performance target could beachieved after the requisite service period. The standard states that a performance target in a share-based payment that affects vesting and that could beachieved after the requisite service period should be accounted for as a performance condition. As such, the performance target should not be reflected inestimating the grant-date fair value of the award. The guidance became effective for all entities during the first quarter of fiscal 2016. The Companypreviously accounted for awards in a manner consistent with the new guidance and as such, adoption of the guidance did not have any impact on theCompany’s consolidated financial statements.As of December 31, 2016, there were an aggregate of 21,188,014 stock options and 10,143,176 restricted stock units (“RSUs”) outstanding, representingapproximately 6% and 3%, respectively, of outstanding shares (including common and preferred shares) on a fully diluted basis.During the years ended December 31, 2016 and 2015, the Company issued 177,146 and 18,020 shares, respectively, as a result of the exercise of stockoptions, resulting in gross and net proceeds of $0.3 million during the year ended December 31, 2016 and $31 thousand during the year ended December 31,2015.On July 11, 2016, the Company granted a total of 148,403 RSUs and 208,340 stock options to members of the Company’s Board of Directors under theAmarin Corporation plc Stock Incentive Plan (the “2011 Plan”). The RSUs vest in equal installments over a three-year period upon the earlier of theanniversary of the grant date or the Company’s annual general meeting of shareholders in such anniversary year. The stock options vest in full upon theearlier of the one-year anniversary of the grant date or the Company’s annual general meeting of shareholders in such anniversary year. Upon termination ofservice to the Company or upon a change of control, each Director shall be entitled to a payment equal to the fair market value of one share of Amarincommon stock, which is required to be made in shares.On February 1, 2016, the Company granted a total of 1,607,500 RSUs and 2,442,000 stock options to employees under the 2011 Plan. The RSUs vestannually over a three-year period and the stock options vest monthly over a four-year period. F-37Table of ContentsOn July 6, 2015, the Company granted a total of 1,455,000 RSUs and 5,470,000 stock options to employees under the Amarin Corporation plc StockIncentive Plan (the “2011 Plan”). The RSUs granted vest over a four-year period. Of the total stock options granted, 3,670,000 stock options vest over a four-year period while the remaining 1,800,000 stock options vest upon the achievement of certain performance conditions. During the year ended December 31,2016, the Company issued 363,750 common shares related to the vesting of these RSUs, of which 173,563 shares were retained as treasury shares assettlement of employee tax obligations.Also on July 6, 2015, the Company granted a total of 413,500 RSUs and 288,657 stock options to members of the Company’s Board of Directors under the2011 Plan.

Upon termination of service to the Company or upon a change of control, each Director shall be entitled to a payment equal to the fairmarket value of one share of Amarin common stock, which is required to be made in shares.On January 29, 2015, the Company granted a total of 2,564,251 RSUs and 1,622,500 stock options to employees under the 2011 Plan. The RSUs vestannually over a three year period and the stock options vest over a four year period. Also on January 29, 2015, the Company granted 5,455,500 RSUs toemployees under the 2011 Plan that vest upon the achievement of certain performance conditions. The issuance of these performance RSUs was contingentupon shareholder approval to increase the aggregate number of shares authorized for issuance under the 2011 Plan, which was obtained at the Company’sAnnual General Meeting of Shareholders held on July 6, 2015. During the year ended December 31, 2016, the Company issued 818,352 common sharesrelated to the vesting of these RSUs, of which 270,329 shares were retained as treasury shares as settlement of employee tax obligations.See Note 12—Stock Incentive Plans and Stock Based Compensation for further information regarding the Company’s incentive equity awards.WarrantsDuring the year ended December 31, 2015, the Company issued 1,844,585 shares upon the exercise of warrants, resulting in gross and net proceeds of$2.8 million and $2.7 million, respectively. There was no warrant activity during the year ended December 31, 2016 and no warrants remained outstanding asof December 31, 2016.(11) Income TaxesInterest and penalties related to any uncertain tax positions have historically been insignificant. The Company recognizes interest and penalties related touncertain tax positions within the provision for income taxes. The total amount of unrecognized tax benefits that would affect the Company’s effective taxrate if recognized is $1.5 million as of December 31, 2016 and $1.4 million as of December 31, 2015.The following is a reconciliation of the total amounts of unrecognized tax benefits for the years ended December 31, 2016, 2015 and 2014: In thousands 2016 2015 2014 Beginning uncertain tax benefits $1,550 $2,487 $1,674 Prior year—increases — 120 — Prior year—decreases — (762) — Current year—increases 83 144 1,067 Current year—decreases for lapses in statutes of limitations — (439) (254) Ending uncertain tax benefits $1,633 $1,550 $2,487 F-38Table of ContentsThe Company files income tax returns in the United States, Ireland and United Kingdom, or UK. The Company remains subject to tax examinations in thefollowing jurisdictions as of December 31, 2016: Jurisdiction Tax Years United States—Federal 2013-2016 United States—State 2012-2016 Ireland 2012-2016 United Kingdom 2015-2016 The Company expects gross liabilities of $59,000 to expire in 2017 based on statutory lapses.The components of loss from operations before taxes were as follows for the years ended December 31, 2016, 2015 and 2014: In thousands 2016 2015 2014 United States $(8,115) $(10,137) $(7,331) Ireland and United Kingdom (68,266) (108,153) (51,870) $(76,381) $(118,290) $(59,201) The (provision for) benefit from income taxes shown in the accompanying consolidated statements of operations consists of the following for fiscal 2016,2015 and 2014: In thousands 2016 2015 2014 Current: Federal-U.S. $1,033 $1,053 $660 State-U.S. 138 113 117 Total current $1,171 $1,166 $777 Deferred: Federal-U.S. (4,001) (3,343) (3,689) State-U.S. (334) (605) (226) Ireland and United Kingdom (143) (9,023) 3,335 Change in valuation allowance 13,276 8,719 (3,034) Total deferred $8,798 $(4,252) $(3,614) Provision for (benefit from) income taxes $9,969 $(3,086) $(2,837) The (provision for) benefit from income taxes differs from the amount computed by applying the statutory income tax rate to income before taxes due to thefollowing for fiscal 2016, 2015 and 2014: In thousands 2016 2015 2014 Benefits from taxes at statutory rate $(19,039) $(29,572) $(14,786) Rate differential 4,667 8,572 9,493 Change in valuation reserves 13,276 8,719 (3,034) Derivative liabilities (668) 187 (2,706) Gain on extinguishment of debt — (328) (9,509) Research and development credits (1,689) (1,284) (1,455) Tax return to provision adjustments 4,524 2,248 10,026 Cumulative translation adjustment 7,385 7,811 8,061 Permanent and other (409) (1,033) 1,073 Non-deductible interest expense 1,922 1,594 — Provision for (benefit from) income taxes $9,969 $(3,086) $(2,837) F-39Table of ContentsDuring 2016, the Company recorded adjustments to its deferred tax accounts related to the impact of foreign exchange rate changes and to reconcile thefinancial statement accounts to the amounts reported on its filed 2015 foreign tax returns, primarily for the impact of U.S. GAAP to local statutoryadjustments. The majority of these adjustments were fully offset with valuation allowances based on the Company’s position with respect to the realizabilityof its recorded deferred tax assets. The Company is subject to corporate tax rate in Ireland of 25% for non-trading activities and 12.5% for trading activities.For the years ended December 31, 2016, 2015, and 2014, the Company applied the statutory corporate tax rate of 25% for Amarin Corporation plc, reflectingthe non-trading tax rate in Ireland. However, for Amarin Pharmaceuticals Ireland Limited, a wholly-owned subsidiary of Amarin Corporation plc, theCompany applied the 12.5% Irish trading tax rate. In the table above, the Company used Amarin Corporation plc’s 25% tax rate as the starting point for thereconciliation since it is the parent entity of the business.In November 2015, the FASB issued ASU 2015-17, Income Taxes (Topic 740): “Balance Sheet Classification of Deferred Taxes”, which changes howdeferred taxes are classified on organizations’ balance sheets. The ASU eliminates the current requirement for organizations to present deferred tax liabilitiesand assets as current and non-current in a classified balance sheet. Instead, organizations will be required to classify all deferred tax assets and liabilities asnon-current. The Company early adopted ASU 2015-17 effective December 31, 2015 on a prospective basis. Adoption of this ASU resulted in areclassification of $0.9 million of the net current deferred tax asset to the net non-current deferred tax asset in the consolidated balance sheet as ofDecember 31, 2015. No prior periods were retrospectively adjusted.In April 2016, the Company adopted ASU No. 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Share-Based PaymentAccounting which changes the accounting for certain aspects of share-based payments to employees. One aspect of the standard requires that excess taxbenefits and deficiencies that arise upon vesting or exercise of share-based payments be recognized as an income tax benefit and expense in the incomestatement. Previously, such amounts were recognized as an increase and decrease in additional paid-in capital. This aspect of the standard was adoptedprospectively, and accordingly the provision for income taxes for the year ended December 31, 2016 includes $0.4 million of excess tax deficiencies arisingfrom share-based payments during the period of adoption. Additionally, the new standard requires that historical excess tax benefits were not previouslyrecognized because the related tax deduction had not reduced current taxes should be recognized on a modified retrospective basis as a cumulative-effectadjustment to retained earnings as of the beginning of the annual period of adoption. Consequently, the Company recognized deferred tax assets ofapproximately $1.6 million relating to excess tax benefits on stock-based compensation outstanding as of December 31, 2015, with a correspondingcumulative-effect adjustment to accumulated deficit.The income tax effect of each type of temporary difference comprising the net deferred tax asset as of December 31, 2016 and 2015 is as follows: In thousands 2016 2015 Deferred tax assets: Net operating losses $88,345 $88,996 Stock based compensation 23,731 17,975 Depreciation — 74 Tax credits 6,893 6,030 Other reserves and accrued liabilities 2,437 2,796 Gross deferred tax assets 121,406 115,871 Less: valuation allowance (109,274) (95,999) Total deferred tax assets 12,132 19,872 Deferred tax liabilities: Depreciation (1,050) — Total deferred tax liabilities (1,050) — Net deferred tax assets $11,082 $19,872 F-40Table of ContentsThe Company assesses whether it is more-likely-than-not that the Company will realize its deferred tax assets. The Company determined that it wasmore-likely-than-not that the Irish, UK, and Israeli net operating losses and the related deferred tax assets would not be realized in future periods and a fullvaluation allowance has been provided for all periods.The following table reflects the activity in the valuation allowance for the years ended December 31, 2016 and 2015: In thousands 2016 2015 Beginning valuation allowance $95,999 $85,965 Increase as reflected in income tax expense 17,951 16,291 Increase as reflected in retained earnings — 1,315 Cumulative translation adjustment (4,676) (7,572) Ending valuation allowance $109,274 $95,999 The Company has combined Irish, UK, and Israeli net operating loss carryforwards of $573.8 million, which do not expire. The total net operating losscarryforwards increased by approximately $8.1 million from the prior year primarily as a result of current year losses generated by the Company’s Irishsubsidiaries, partially offset by the impact of foreign exchange rate changes and adjustments to reconcile the financial statement accounts to the amountsreported on the filed 2015 foreign tax returns. In addition, the Company has U.S. Federal tax credit carryforwards of $6.7 million and state tax creditcarryforwards of $1.6 million. These amounts exclude the impact of any unrecognized tax benefits and valuation allowances. These carryforwards, which willexpire starting between 2024 and 2036 may be used to offset future taxable income, if any.As of December 31, 2016, earnings of $25.1 million have been retained indefinitely for reinvestment by foreign subsidiary or there is an expectation that anyreinvestment can be recovered tax-free without significant cost, and the entity expects to ultimately use that means of recovery for domestic subsidiarycompanies; therefore, no provision has been made for income taxes that would be payable upon the distribution of such earnings and it would not bepracticable to determine the amount of the related unrecognized deferred income tax liability.The Company’s and its subsidiaries’ income tax returns are periodically examined by various taxing authorities. The Company is currently under audit bythe United States Internal Revenue Service (IRS) for the years 2013 to 2014. Although the outcome of tax audits is always uncertain and could result insignificant cash tax payments, the Company does not believe the outcome of these audits will have a material adverse effect on the Company’s consolidatedfinancial position or results of operations.(12) Stock Incentive Plans and Stock Based CompensationOn April 29, 2011 the Board, upon the recommendation of the Remuneration Committee, adopted the 2011 Stock Incentive Plan (“2011 Plan”), which wasapproved by the Company’s shareholders on July 12, 2011. The 2011 Plan replaced the Company’s 2002 Stock Option Plan (“2002 Plan”), which expired onJanuary 1, 2012. The maximum number of the Company’s Ordinary Shares of £0.50 each or any ADS’s, as to be issued under the 2011 Plan shall not exceedthe sum of (i) 31.5 million newly authorized Shares available for award and (ii) the number of Shares that remained available for grants under the Company’s2002 Plan and (iii) the number of Shares underlying then outstanding awards under the 2002 Plan that could be subsequently forfeited, cancelled, expire orare otherwise terminated. The award of stock options (both incentive and non-qualified options) and restricted stock units, and awards of unrestricted Sharesto Directors are permitted. The 2011 Plan is administered by the Remuneration Committee of the Company’s Board of Directors and expires on July 12, 2021.In addition to the grants under the 2011 Plan, the Company grants non-qualified stock options to employees to purchase the Company’s ordinary shares.These grants are made pursuant to employment agreements on terms consistent with the 2011 Plan. F-41Table of ContentsUnder the terms of the 2011 Plan, and grants made pursuant to employment agreements, options typically vest over a four-year period, expire after a ten-yearterm and are granted at an exercise price equal to the closing price of the Company’s American Depositary Shares on the grant date. The following tablesummarizes all stock option activity for the year ended December 31, 2016: In thousands (except per share amounts and years) Number ofShares WeightedAverageExercisePrice WeightedAverageRemainingContractualTerm AggregateIntrinsicValue Outstanding as of January 1, 2016 17,818 $3.76 Granted 4,400 1.62 Forfeited (688) 1.92 Expired (165) 7.24 Exercised (177) 1.62 Outstanding as of December 31, 2016 21,188 3.37 7.3 years $17,018 Exercisable as of December 31, 2016 12,217 4.38 6.3 years $7,159 Vested and expected to vest as of December 31, 2016 20,513 3.41 7.3 years $16,396 Available for future grant as of December 31, 2016 4,304 The weighted average grant date fair value of stock options granted during the years ended December 31, 2016, 2015 and 2014 was $1.62, $2.16, and $1.58,respectively. The total grant date fair value of options vested during the years ended December 31, 2016, 2015 and 2014 was $6.5 million, $9.1 million, and$8.1 million, respectively.During the years ended December 31, 2016, 2015 and 2014, the Company received proceeds from the exercise of options of $0.3 million, $31 thousand, and$0.3 million, respectively. The total intrinsic value of options exercised during the years ended December 31, 2016, 2015 and 2014 was $0.2 million,$6 thousand, and $0.2 million, respectively, calculated as the difference between the quoted stock price of the Company’s common stock as of the reportingdate and the exercise prices of the underlying awards.As of December 31, 2016, there was $11.8 million of unrecognized stock-based compensation expense related to unvested stock option share-basedcompensation arrangements granted under the Company’s stock award plans. This expense is expected to be recognized over a weighted-average period ofapproximately 2.5 years. The Company recognizes compensation expense for the fair values of those awards which have graded vesting on a straight linebasis.The fair value of stock options on the date of grant was estimated using the Black-Scholes option pricing model. Use of a valuation model requiresmanagement to make certain assumptions with respect to selected model inputs. Expected stock price volatility was calculated based on the historicalvolatility of the Company’s common stock over the expected life of the option. The expected life was determined using the short-cut method based on theterm and vesting period. The risk-free interest rate is based on zero-coupon U.S. Treasury securities with a maturity term approximating the expected life ofthe option at the date of grant. No dividend yield has been assumed as the Company does not currently pay dividends on its common stock and does notanticipate doing so in the foreseeable future. Estimated forfeitures are based on the Company’s historical forfeiture activity.Employee stock options generally vest over a four-year service period and all stock options are settled by the issuance of new shares. Compensation expenserecognized for all option grants is net of estimated forfeitures and is recognized over the awards’ respective requisite service periods. The vesting of certainstock options is contingent upon the attainment of performance criteria. The probability that such criteria will be achieved is assessed by management andcompensation expense for such awards is only recorded to the extent that the F-42Table of Contentsattainment of the performance criteria is deemed to be probable.

The Company will retain all Vascepa manufacturing rights. Eddingpharm has agreed to certain restrictions regarding the commercializationof competitive products globally and the Company has agreed to certain restrictions regarding the commercialization of competitive products in the ChinaTerritory.The Company and Eddingpharm agreed to form a joint development committee to oversee regulatory and development activities for Vascepa in the ChinaTerritory in accordance with a negotiated development plan and F-45®Table of Contentsto form a separate joint commercialization committee to oversee Vascepa commercialization activities in the China Territory.

Neither party may assign or transfer the DCS Agreement without the prior consent ofthe other party, provided that the Company may assign the DCS Agreement in the event of a change of control transaction.Upon closing of the DCS Agreement, the Company received a non-refundable $15.0 million up-front payment, which it will recognize as revenue over theestimated period in which the Company is required to provide initial and on-going regulatory and development support and clinical supply for obtainingregulatory approvals in the China Territory and through the estimated period in which the Company is required to provide commercial supply, which iscurrently estimated to be a period of approximately 16 years. In March 2016, Eddingpharm submitted its clinical trial application (“CTA”) with respect to theMARINE indication for Vascepa to the Chinese regulatory authority. Following the CTA submission, the Company received a non-refundable $1.0 millionmilestone payment which it will recognize as revenue over the estimated period in which the Company is required to provide on-going development supportneeded to support the successful approval for a new drug application, which is currently estimated to be a period of approximately four years.In addition to the non-refundable, up-front and regulatory milestone payments described above, the Company is entitled to receive certain regulatory andsales-based milestone payments of up to an additional $153.0 million as well as tiered double-digit percentage royalties on net sales of Vascepa in the ChinaTerritory escalating to the high teens. The regulatory milestone events relate to the submission and approval of certain applications to the applicableregulatory authority, such as a clinical trial application, clinical trial exemption, or import drug license application. The amounts to be received uponachievement of the regulatory milestone events relate to the submission and approval for three indications, and range from $1.0 million to $15.0 million for atotal of $33.0 million. The sales-based milestone events occur when annual aggregate net sales of Vascepa in the territory equals or exceeds certain specifiedthresholds, and range from $5.0 million to $50.0 million for a total of $120.0 million. Each such milestone payment shall be payable only once regardless ofhow many times the sales milestone event is achieved. Each such milestone payment is non-refundable and non-creditable against any other milestonepayments. The Company recognizes contingent consideration from activities that is earned upon the achievement of a substantive milestone in the period inwhich the milestone is achieved.On March 8, 2016, the Company entered into an agreement with Biologix FZCo (“Biologix”), a company incorporated under the laws of the United ArabEmirates, to register and commercialize Vascepa in several Middle Eastern and North African countries. Under the terms of the distribution agreement, theCompany granted to Biologix a non-exclusive license to use its trademarks in connection with the importation, distribution, promotion, marketing and saleof Vascepa in the Middle East and North Africa territory. Upon closing of the agreement, the Company received a non-refundable up-front payment, whichwill be recognized as revenue over 10 years commencing upon first marketing approval of Vascepa in the territory. The Company is entitled to receivepayments based on product sales at an agreed-upon transfer price, which represents a percentage of gross selling price, subject to a minimum floor price. F-46Table of ContentsLicensing and deferred revenues currently consist of revenue attributable to receipt of up-front, non-refundable payments and milestone payments related tothe Eddingpharm and Biologix agreements. Up-front and milestone payments under such agreements are typically recognized as licensing revenue over theestimated period in which the Company is required to provide regulatory and development support and clinical and commercial supply pursuant to theagreements. During the years ended December 31, 2016 and 2015, the Company recognized $1.1 million and $0.8 million of up-front and milestonepayments as licensing revenue in connection with the Eddingpharm DCS Agreement, respectively, and recorded $15.1 million as deferred revenue as ofDecember 31, 2016.(18) Subsequent EventsThe Company has evaluated subsequent events from December 31, 2016 through the date of the issuance of these consolidated financial statements.On January 19, 2017, holders of the 2012 Notes exercised their option to put the 2012 Notes to the Company at a price equal to 100% of the principalamount of the 2012 Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the repurchase date. As a result, the Company repurchasedapproximately $15.0 million in aggregate principal amount of 2012 Notes, such that $0.1 million in principal amount of 2012 Notes remains outstanding.In contemplation of this surrender of 2012 Notes for repurchase, on January 20, 2017, the Company and its wholly owned subsidiary, Corsicanto IIDesignated Activity Company (“Corsicanto II”), entered into separate, privately negotiated purchase agreements with certain investors pursuant to which theCorsicanto II issued and sold $30.0 million in aggregate principal amount of 3.5% Exchangeable Senior Notes due 2047 (the “2017 Notes”), which areguaranteed by the Company, at an issue price of 100%. The transaction closed on January 25, 2017.The 2017 Notes will be issued pursuant to an Indenture (the “Indenture”), to be entered into by the Company, Corsicanto II and Wilmington Trust, NationalAssociation, as trustee (the “Trustee”).

If prior to January 19, 2021, a make-wholefundamental change (as defined in the Indenture) occurs and a holder elects to exchange its 2017 Notes in connection with such make-whole fundamentalchange, such holder may be entitled to an increase in the exchange rate as described in the Indenture.The exchange rate will initially be 257.2016 ADSs per $1,000 principal amount of the 2017 Notes (equivalent to an initial exchange price of approximately$3.89 per ADS), subject to adjustment in certain circumstances. The initial exchange price for the 2017 Notes represents a premium of approximately 35%over the last reported sale price of $2.88 per share of the Company’s ADSs on The NASDAQ Global Market on January 19, 2017. Upon exchange, the 2017Notes are to be settled in ADSs. The exchange rate is subject to adjustment from time to time upon the occurrence of certain events, including, but not limitedto, the payment of cash dividends. In the event of physical settlement, the 2017 Notes would be exchangeable into a total of 7,716,048 ADSs based on theinitial exchange rate.Prior to January 19, 2021, Corsicanto II may not redeem the 2017 Notes at its option other than in connection with certain changes in the tax law of a relevanttaxing jurisdiction that results in additional amounts (as defined F-47Table of Contentsin the Indenture) becoming due with respect to payments and/or deliveries on the 2017 Notes. On or after January 19, 2021, Corsicanto II may redeem forcash all or a portion of the 2017 Notes at a redemption price of 100% of the aggregate principal amount of the 2017 Notes to be redeemed, plus accrued andunpaid interest to, but not including, the redemption date.

In addition, holders of the 2017Notes may require Corsicanto II to repurchase all or any portion of the 2017 Notes on January 19, 2022 for cash at a price equal to 100% of the aggregateprincipal amount of the 2017 Notes to be repurchased, plus accrued and unpaid interest to, but not including, the repurchase date.Corsicanto II may elect at its option to cause all or any portion of the 2017 Notes to be mandatorily exchanged in whole or in part at any time prior to theclose of business on the business day preceding January 15, 2047 if the Daily VWAP (as defined in the Indenture) equals or exceeds 130% of the ExchangePrice then in effect for at least 20 VWAP Trading Days (as defined in the Indenture) in any 30 consecutive VWAP Trading Day period. Corsicanto II may onlyexercise its optional exchange rights upon satisfaction of specified equity conditions, including that the ADSs issuable upon exchange of the 2017 Notes beeligible for resale without registration by non-affiliates and listed on The NASDAQ Global Market, its related exchanges or the New York Stock Exchange. IfCorsicanto II elects to exercise its optional exchange rights on or prior to January 19, 2021, each holder whose 2017 Notes are exchanged may uponexchange receive a specified number of additional ADSs as set forth in the Indenture.The net proceeds from the offering were approximately $28.9 million after deducting placement agent fees and estimated offering expenses payable by theCompany. A portion of the net proceeds from the offering replenished approximately $15.0 million of cash on hand that the Company used to purchasesubstantially all of the 2012 Notes. The Company anticipates that it will use the remainder of the net proceeds from the offering for general corporate andworking capital purposes.The Company has initiated the process to redeem the remaining $0.1 million of 2012 Notes, which is expected to be completed in the first quarter of 2017.
