Significant Accounting Policies | (2) Significant Accounting Policies Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Use of Estimates Accounting estimates are based on historical experience and other factors that are considered reasonable under the circumstances. Estimates are used in determining such items as provisions for sales returns, rebates and incentives, chargebacks, and other sales allowances; depreciable/amortizable lives; asset impairments; valuation allowance on deferred taxes; probabilities of achievement of performance conditions for certain equity awards; amounts recorded for licensing revenue; contingencies and accruals; and valuations of derivative and long-term debt instruments. Because of the uncertainties inherent in such estimates, actual results may differ from these estimates. Management periodically evaluates estimates used in the preparation of the consolidated financial statements for continued reasonableness. Use of Forecasted Financial Information in Accounting Estimates The use of forecasted financial information is inherent in many of the Company’s accounting estimates including, but not limited to, determining the estimated fair values of derivatives, debt instruments and intangible assets, and evaluating the need for valuation allowances for deferred tax assets. Such forecasted financial information is comprised of numerous assumptions regarding the Company’s future revenues, cash flows, and operational results. Management believes that its financial forecasts are reasonable and appropriate based upon current facts and circumstances. Because of the inherent nature of forecasts, however, actual results may differ from these forecasts. Management regularly reviews the information related to these forecasts and adjusts the carrying amounts of the applicable assets prospectively, if and when actual results differ from previous estimates. Revenue Recognition The 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, 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 is reasonably assured and (iv) the price is fixed or determinable. The Company commenced its commercial launch in the United States in January 2013. Prior to 2013, the Company recognized no revenue from Vascepa sales. In accordance with GAAP, until the Company had the ability to reliably estimate returns of Vascepa from its Distributors, revenue was recognized based on the resale of Vascepa for the purposes of filling patient prescriptions, and not based on sales from the Company to such Distributors. During the three months ended March 31, 2014, the Company concluded that it had developed sufficient history such that it can reliably estimate returns and as a result, began to recognize revenue based on sales to its Distributors. The change in revenue recognition methodology resulted in the recognition of previously deferred revenue. As of December 31, 2013, the Company had deferred approximately $1.7 million in amounts billed to Distributors that was not recognized as revenue. This change in revenue recognition methodology resulted in the recognition of such deferred revenues in the three months ended March 31, 2014. The Company has contracts with its primary Distributors and delivery occurs when a Distributor receives Vascepa. The Company evaluates the creditworthiness 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 or when the product is utilized. In order to conclude that the price is fixed or determinable, the Company must be able to (i) calculate its gross product revenues from the sales to Distributors and (ii) reasonably estimate its net product revenues. The Company calculates gross product revenues based on the wholesale acquisition cost that the Company charges its Distributors for Vascepa. The Company estimates its net 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 payor rebates, chargebacks and discounts, such as Medicaid reimbursements, (c) reserves for expected product returns and (d) estimated costs of incentives offered to certain indirect customers, including patients. Trade Allowances: Rebates, Chargebacks and Discounts: Product Returns: Other Incentives: The following table summarizes activity in each of the net product revenue allowance and reserve categories described above for the years ended December 31, 2015 and 2014 (in thousands): Trade Allowances Rebates, Chargebacks and Discounts Product Returns Other Incentives Total Balance as of January 1, 2014 $ 1,071 $ 1,137 $ 72 $ 189 $ 2,469 Provision related to current period sales 8,157 12,753 397 11,153 32,460 Provision related to prior period sales (29 ) (80 ) 12 (31 ) (128 ) Credits/payments made for current period sales (5,950 ) (9,143 ) — (10,338 ) (25,431 ) Credits/payments made for prior period sales (1,042 ) (1,057 ) — (181 ) (2,280 ) Balance as of December 31, 2014 $ 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 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. Multiple-Element Arrangements and Licensing Revenue When evaluating multiple-element arrangements, the Company identifies the deliverables included within the agreement and evaluates which deliverables represent separate units of accounting based on whether the delivered element has stand-alone value to the customer or if the arrangement includes a general right 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 price used for each separable element will be based on vendor specific objective evidence (“VSOE”) if available, third-party evidence if VSOE is not available, or estimated selling price if neither VSOE nor third-party evidence is available. Revenue is then recognized as each of the separable elements to which the revenue has been allocated is delivered. The Company may receive up-front, non-refundable payments when licensing its intellectual property in conjunction with research, development and commercialization agreements. In determining the units of accounting, management evaluates whether the license has stand-alone value from the undelivered elements to the collaborative partner based on the consideration of the relevant facts and circumstances for each arrangement. Factors considered in this determination include the stage of development of the license delivered, research and development capabilities of the partner and the ability of partners 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 the arrangement, the Company generally recognizes revenue attributable to the license over the Company’s contractual or estimated performance period. Any unrecognized portion of license revenue is classified within deferred revenue in the accompanying consolidated balance sheets. When management believes the license to its intellectual property has stand-alone value, the Company recognizes revenue attributed to the license upon delivery. The periods over which revenue is recognized is subject to estimates by management and may change over the course of the agreement. Such a change could have a material impact on the amount of revenue the Company records in future periods. Milestones Contingent consideration from activities that is earned upon the achievement of a substantive milestone is recognized in its entirety in the period in which the milestone is achieved. At the inception of each arrangement that includes milestone payments, the Company evaluates whether each milestone is substantive. This evaluation includes an assessment of whether: (a) the consideration is commensurate with either (1) the entity’s performance to achieve the milestone, 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 the milestone, (b) the consideration relates solely to past performance and (c) the consideration is reasonable relative to all of the deliverables and payment terms within the arrangement. The Company evaluates factors such as the scientific, clinical, regulatory, commercial and other risks that must be overcome to achieve the respective milestone, the level of effort and investment required and whether the milestone consideration is reasonable relative to all deliverables and 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 related to the Company’s multiple-element arrangement with Eddingpharm (Asia) Macao Commercial Offshore Limited. Distribution Costs The Company records distribution costs related to shipping product to its customers, primarily through the use of common carriers or external distribution services, in cost of goods sold. Cash and Cash Equivalents and Restricted Cash Cash and cash equivalents consist of cash, deposits with banks and short-term highly liquid money market instruments with remaining maturities at the date of purchase of 90 days or less. Restricted cash represents cash and cash equivalents pledged to guarantee repayment of certain expenses which may be incurred for business travel under corporate credit cards held by employees. Accounts Receivable, net Accounts receivable, net, comprised of trade receivables, are generally due within 30 days and are stated at amounts due from customers. The Company does not currently maintain an allowance for doubtful accounts and 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, 2015 and 2014 (in thousands): December 31, 2015 December 31, 2014 Gross trade accounts receivable $ 18,270 $ 10,215 Trade allowances (4,296 ) (2,207 ) Chargebacks (148 ) (166 ) Accounts receivable, net $ 13,826 $ 7,842 Inventory The Company states inventories at the lower of cost or market value. Cost is determined based on actual cost using the average cost method. An allowance is established when management determines that certain inventories may not be saleable. If inventory cost exceeds expected market value due to obsolescence, damage or quantities in excess of expected demand, the Company will reduce the carrying value of such inventory to market value. The Company received FDA approval for Vascepa on July 26, 2012 and after that date began capitalizing inventory purchases of saleable product from approved suppliers. Until an active pharmaceutical ingredient, or API, supplier is approved, all Vascepa API purchased from such supplier is included as a component of research and development expense. Upon sNDA approval of each additional supplier, the Company capitalizes subsequent Vascepa API purchases from such supplier as inventory. Purchases of Vascepa API received and expensed before such regulatory approvals is not subsequently capitalized, and all such purchases are quarantined and not used for commercial supply until such time as the sNDA for the supplier that produced the API is approved. The Company expenses inventory identified for use as marketing samples when they are packaged. The average cost reflects the actual purchase price of Vascepa API. Property, Plant and Equipment The Company provides for depreciation and amortization using the straight-line method by charges to operations in amounts that depreciate the cost of the fixed asset over its estimated useful life. The estimated useful lives, by asset classification, are as follows: Asset Classification Useful Lives Computer equipment and software 3 - 5 years Furniture and fixtures 5 years Leasehold improvements Lesser of useful life or lease term Upon retirement or sale of assets, the cost of the assets disposed and the related accumulated depreciation are removed from the balance sheet and any resulting gain or loss is credited or expensed to operations. Repairs and maintenance costs are expensed as incurred. Long-Lived Asset Impairment The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of these assets is determined by comparing the forecasted undiscounted net cash flows of the operation to which the assets relate to their carrying amount. If impairment is indicated, the assets are written down to fair value. Fair value is determined based on discounted forecasted cash flows or appraised values, depending on the nature of the assets. Intangible Asset, net Intangible asset, net consists of a milestone payment paid to the former shareholders of Laxdale Limited related to the 2004 acquisition of the rights to Vascepa, which is the result of Vascepa receiving marketing approval for the first indication and is amortized over its estimated useful life on a straight-line basis. See Note 9—Commitments and Contingencies for further information regarding other obligations related to the acquisition of Laxdale Limited. Beneficial Conversion Features The Company issued Series A preference shares in a private placement transaction executed in two tranches that each contain a conversion feature whereby such 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’s ordinary shares. It was determined that these discounts represent contingent beneficial conversion features, which were valued based on the difference between the conversion price and the market price of the ordinary shares on the date of issuance, which is the commitment date. These features are analogous to preference dividends and were each recorded as a non-cash return to preferred shareholders through accumulated deficit upon the earliest possible date of conversion, which occurred in the three months ended June 30, 2015 upon effectiveness of the related resale Registration Statement on Form S-3 and in the three 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 Proceedings Costs for patent litigation or other legal proceedings are expensed as incurred and included in selling, general and administrative expenses. Research and Development Costs The Company charges research and development costs to operations as incurred. Research and development expenses are comprised of costs incurred by the Company in performing research and development activities, including: salary and benefits; stock-based compensation expense; laboratory supplies and other direct expenses; contractual services, including clinical trial and pharmaceutical development costs; commercial supply investment in its drug candidates; and infrastructure costs, including facilities costs and depreciation expense. In addition, research and development costs include the costs of product supply received from suppliers when such receipt by the Company is prior to regulatory approval of the supplier. Selling, General and Administrative Costs The 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 the 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 to Kowa Pharmaceuticals America, Inc. Income Taxes Deferred tax assets and liabilities are recognized for the future tax consequences of differences between the carrying amounts and tax bases 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. The Company provides reserves for potential payments of tax to various tax authorities or does not recognize tax benefits related to uncertain tax positions and 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 or positions 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 is to record interest and penalties in the provision for income taxes. The Company regularly assesses the realizability of deferred tax assets. Changes in historical earnings performance and future earnings projections, among other factors, may cause the Company to adjust its valuation allowance on deferred tax assets, which would impact the Company’s income tax expense in the period in which it is determined that these factors have changed. Derivative Instruments Derivative financial liabilities are recorded at fair value, with gains and losses arising for changes in fair value recognized in the statement of operations at each period end while such instruments are outstanding. If the Company issues shares to discharge the liability, the derivative financial liability is derecognized and common stock and additional paid-in capital are recognized on the issuance of those shares. Warrants are valued using a Black-Scholes option pricing model. The long-term debt redemption features are valued using probability-weighted models incorporating management estimates for potential 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 reclassified out 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 and additional paid-in capital. Loss per Share Basic net loss per share is determined by dividing net loss by the weighted average shares of common stock outstanding during the period. Diluted net loss per share is determined by dividing net loss by diluted weighted average shares outstanding. Diluted weighted average shares reflects the dilutive effect, if any, of potentially dilutive common shares, such as common stock options and warrants calculated using the treasury stock method and convertible notes using the “if-converted” method. In periods with reported net operating losses, all common stock options and warrants are deemed anti-dilutive such that basic 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 fair value 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 to determine 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 of the 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 to present 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 earnings during 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, 2015, 2014 and 2013 are as follows: In thousands 2015 2014 2013 Net loss $ (115,204 ) $ (56,364 ) $ (166,227 ) Preferred stock purchase option (see Note 10) (868 ) — — Preferred stock beneficial conversion features (see Note 10) (32,987 ) — — Net loss applicable to common shareholders—basic (149,059 ) (56,364 ) (166,227 ) Gain on warrant derivative liability — (6,775 ) (47,936 ) Net loss—diluted (149,059 ) (63,139 ) (214,163 ) Net loss per share—basic $ (0.83 ) $ (0.32 ) $ (1.03 ) Weighted average shares outstanding—basic 180,654 173,719 161,022 Effect of dilutive warrants — 105 6,048 Weighted average shares outstanding—diluted 180,654 173,824 167,070 Net loss per share—diluted $ (0.83 ) $ (0.36 ) $ (1.28 ) For the years ended December 31, 2015, 2014 and 2013, the following potentially dilutive securities were not included in the computation of net loss per share because the effect would be anti-dilutive: In thousands 2015 2014 2013 Stock options 17,818 10,670 9,330 Restricted stock and restricted stock units 10,887 2,256 196 Warrants — — 1,702 Exchangeable senior notes (if converted) 59,407 49,215 17,021 Preferred stock (if converted) 32,818 — — Debt Instruments Debt instruments are initially recorded at fair value, with coupon interest and amortization of debt issuance discounts recognized in the statement of operations as interest expense each period in which such instruments are outstanding. If the Company issues shares to discharge the liability, the debt obligation is derecognized and common stock and additional paid-in capital are recognized on the issuance of those shares. The conversion features in the 2012 Notes, the 2014 Notes and the 2015 Notes qualify for the exception from derivative accounting in accordance with ASC 815-40. The 2012 Notes may be settled, at the Company’s discretion, in any combination of ADSs or cash upon conversion and have been accounted for in accordance with ASC 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 to determine the proceeds allocated to the conversion option, which has been recorded in equity. The difference between the initial fair value of the liability component and the amount repayable is amortized over the expected term of the instrument. The conversion features in the 2014 Notes and 2015 Notes may only be settled in ADSs upon conversion and have been accounted for as part of the debt host. The conversion options in the 2012 Notes, 2014 Notes and 2015 Notes continue to be evaluated on a quarterly basis to determine if they still receive an exception from derivative accounting 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 2012 Notes. 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 of the 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 are being amortized through interest expense over the expected terms of the 2014 Notes and 2015 Notes, which is through January 2019 for each. See Note 8—Debt for further discussion. Stock-Based Compensation Stock-based compensation cost is generally measured at the grant date, based on the fair value of the award, and is recognized as compensation expense over the requisite service period. For awards with performance conditions, if the achievement of the performance conditions is deemed probable, the Company recognizes compensation expense based on the fair value of the award over the estimated service period. The Company reassesses the probability of achievement of the performance conditions for such awards each reporting period. Concentration of Credit Risk Financial instruments that potentially subject the Company to credit risk consist primarily of cash and cash equivalents and accounts receivable. The Company 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 to whom 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, 2015 and 2014, and represented 95% and 96% of the gross accounts receivable balance as of December 31, 2015 and 2014, respectively. The Company has not experienced any write-offs of its accounts receivable. Concentration of Suppliers The Company has contractual freedom to source the API for Vascepa and has entered into supply agreements with multiple suppliers. The Company’s supply of product for commercial sale and clinical trials is dependent upon relationships with third-party manufacturers and key suppliers, in particular three suppliers 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 successful or 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 current API supply chain or its failure to enter into new and similar agreements, 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 these companies has qualified its manufacturing processes and is capable of manufacturing Vascepa. There can be no guarantee that these or other suppliers with which the Company may contract in the future to encapsulate API will continue to be qualified to manufacture the product to its specifications or that these and any future suppliers will have the manufacturing capacity to meet anticipated demand for Vascepa. Foreign Currency All 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 of operations. For transactions settled during the applicable period, gains and losses are included in other (expense) income, net in the consolidated statements of operations. Certain amounts payable pursuant to supply contracts are denominated in currencies other than the U.S. dollar. Debt Issuance Costs Debt issuance costs are initially recorded as a deferred cost and amortized to interest expense using the effective interest method over the expected term of the related debt. Unamortized debt issuance costs related to the extinguishment of debt are expensed at the time the debt is extinguished and recorded in other (expense) income, net in the consolidated statements of operations. Fair Value of Financial Instruments The Company provides disclosure of financial assets and financial liabilities that are carried at fair value based on the price that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements may be classified 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 the measurement date. Level 2—Inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that 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 derived principally 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, 2015 and 2014 that are measured at fair value on a recurring basis and indicate the fair value hierarchy of the valuation techniques the Company utilized to determine such fair value: 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 December 31, 2014 In thousands Total Level 1 Level 2 Level 3 Asset: Cash equivalents—money markets $ 65,156 $ 65,156 $ — $ — Liabilities: Warrant derivative liability $ 119 $ — $ — $ 119 Long-term debt derivative liabilities $ 7,400 $ — $ — $ 7,400 The carrying amounts of cash, cash equivalents, accounts payable and accrued liabilities approximate fair value because of their short-term nature. The carrying amounts and the estimated fair values of debt instruments as of December 31, 2015 and 2014 are as follows: December 31, 2015 December 31, 2014 In thousands Carrying Estimated Carrying Estimated Long-term debt—December 2012 financing $ 91,512 $ 87,700 $ 89,617 $ 81,000 2012 Notes 15,107 13,637 31,266 25,689 2014 Notes 96,364 108,034 90,580 75,533 2015 Notes 27,134 28,448 — — The estimated fair value of the long-term debt pursuant to the December 2012 financing is calculated utilizing the same Level 3 inputs utilized in valuing the related derivative liability (see Long-Term Debt Redemption Features below). The estimated fair value of the 2012 Notes 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 2 quoted bond prices for the 2014 Notes. The carrying value of the 2012 Notes as of December 31, 2015 and 2014 does not include a debt discount, as it had been fully amortized as non-cash interest expense over the expected term of the 2012 Notes. The carrying value of the 2014 Notes as of December 31, 2015 and 2014 includes a debt discount of $22.4 million and $28.2 million, respectively, which is being amortized as non-cash interest expense over the expected term of the 2014 Notes, through January 2019. The carrying value of the 2015 Notes as of December 31, 2015 includes a debt discount of $4.1 million, which is being amortized as non-cash interest expense over the expected term of the 2015 Notes, through January 2019.
