Accounting Policies [Abstract] |
Principles of Consolidation | 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 | 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 | 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, evaluating the need for valuation allowances for deferred tax assets, and assessing the Company’s ability to continue as a going concern. 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 | Revenue Recognition Effective January 1, 2018, the Company adopted Accounting Standards Codification, or ASC, Topic 606, Revenue from Contracts with Customers, using the modified retrospective transition method. Under this method, the Company revised its opening retained earnings balance with a cumulative-effect adjustment of $0.2 million related solely to licensing revenues as of January 1, 2018. This standard applies to all contracts with customers except for contracts that are within the scope of other standards, such as leases, insurance, and financial instruments. Under Topic 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of Topic 606, the entity performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of Topic 606, the Company assesses the goods or services promised within each contract and determines those that are performance obligations and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. For a complete discussion of accounting for net product revenue and licensing revenue, see Note 15—Revenue Recognition.
Distribution Costs | 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 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 Accounts receivable, net, comprised of trade receivables, are generally due within 30 days and are stated at amounts due from customers. The Company recognizes an allowance for losses on accounts receivable in an amount equal to the estimated probable losses net of any recoveries. The allowance is based primarily on assessment of specific identifiable customer accounts considered at risk or uncollectible, as well as an analysis of current receivables aging and expected 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 significant credit losses. The following table summarizes the impact of accounts receivable reserves on the gross trade accounts receivable balances as of December 31, 2018 and 2017:
In thousands |  | December 31, 2018 |  |  | December 31, 2017 |
Gross trade accounts receivable |  | $ | 86,133 |  |  | $ | 57,802 |
Trade allowances |  |  | (19,495 | ) |  |  | (12,035 | )
Chargebacks |  |  | (115 | ) |  |  | (449 | )
Accounts receivable, net |  | $ | 66,523 |  |  | $ | 45,318 |
Inventory | Inventory The Company states inventories at the lower of cost or net realizable value. Cost is determined based on actual cost using the average cost method. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. An allowance is established when management determines that certain inventories may 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 a component of cost of goods sold in the period in which it occurs. The Company capitalizes inventory purchases of saleable product from approved suppliers while inventory purchases from suppliers prior to regulatory approval are included as a component of research and development expense. The Company expenses inventory identified for use as marketing samples when they are packaged. The average cost reflects the actual purchase price of Vascepa active pharmaceutical ingredient, or API.
Property, Plant and Equipment | 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 consolidated 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 | 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 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 8—Commitments and Contingencies for further information regarding other obligations related to the acquisition of Laxdale Limited.
Costs for Patent Litigation and Legal Proceedings | 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 | 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, as well as license fees related to the Company’s strategic collaboration with Mochida Pharmaceutical Co., Ltd.
Selling, General and Administrative Costs | Selling, General and Administrative Costs The Company charges selling, general and administrative costs to operations as incurred. Selling, general and administrative costs include salaries and benefits, stock-based compensation expense, and costs of 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 to Kowa Pharmaceuticals America, Inc. which in 2018 included costs for accrual of tail co-promotion fees.
Income Taxes | Income Taxes On December 22, 2017, the U.S. enacted the Tax Cuts and Jobs Act (the “Act”) which instituted fundamental changes to the taxation of multinational corporations. The Act includes changes to the taxation of foreign earnings by implementing a dividend exemption system, expansion of the current anti-deferral rules, a minimum tax on low-taxed foreign earnings and new measures to deter base erosion. The Act also includes a permanent reduction in the corporate tax rate to 21%, repeal of the corporate alternative minimum tax, expensing of capital investment, and limitation of the deduction of interest expense. Furthermore, as part of the transition to the new tax system, a one-time transition tax is imposed on a U.S. shareholder's historical undistributed earnings of foreign affiliates. The Company applied the guidance in Staff Accounting Bulletin 118 when accounting for the enactment-date effects of the Act in the prior year. As of December 31, 2017, the Company had recorded provisional amounts to account for the impact of tax effects of the Act related to the change in corporate tax rate from 34% to 21% and the changes to executive compensation deductibility. As of December 31, 2018, the Company has completed its accounting for all of the tax effects of the Act. Based on the additional analysis performed, no adjustments to the provisional amounts were made in the reporting period which had an impact to the tax provision or consolidated financial statements. 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. Deferred tax assets and liabilities are classified as non-current in the consolidated balance sheet. 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 its ability to realize deferred tax assets. Changes in historical earnings performance, future earnings projections, and changes in tax laws and tax rates, 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. Excess tax benefits and deficiencies that arise upon vesting or exercise of share-based payments are recognized as an income tax benefit and expense, respectively, in the statement of operations. Excess income tax benefits and are classified as cash flows from operating activities and cash paid to taxing authorities arising from the withholding of shares from employees are classified as cash flows from financing activities. The Company’s and its subsidiaries’ income tax returns are periodically examined by various tax authorities, including the Internal Revenue Service (IRS) and states. The Company recently completed the audit by the IRS for the years 2013 to 2014 with no material changes to the filed income tax returns. Although the outcome of tax audits is always uncertain and could result in significant cash tax payments, the Company does not believe the outcome of these audits will have a material adverse effect on its consolidated financial position or results of operations.
Loss per Share | 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 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 are deemed anti-dilutive such that basic net loss per share and diluted net loss per share are equal. 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, 2018, 2017 and 2016 are as follows:
In thousands |  | 2018 |  |  | 2017 |  |  | 2016 |
Net loss—basic and diluted |  | $ | (116,445 | ) |  | $ | (67,865 | ) |  | $ | (86,350 | )
Weighted average shares outstanding—basic and diluted |  |  | 297,237 |  |  |  | 270,652 |  |  |  | 211,874 |
Net loss per share—basic and diluted |  | $ | (0.39 | ) |  | $ | (0.25 | ) |  | $ | (0.41 | )
For the years ended December 31, 2018, 2017 and 2016, 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 |  | 2018 |  |  | 2017 |  |  | 2016 |  |
Stock options |  |  | 19,263 |  |  |  | 24,108 |  |  |  | 21,188 |  |
Restricted stock and restricted stock units |  |  | 9,633 |  |  |  | 12,006 |  |  |  | 10,143 |  |
Exchangeable senior notes (if converted) |  |  | — |  |  |  | 7,716 |  |  |  | 1,714 |  |
Preferred stock (if converted) |  |  | 28,932 |  |  |  | 32,818 |  |  |  | 32,818 |  |
Debt Instruments | Debt Instruments Debt instruments are initially recorded at fair value, with coupon interest and amortization of debt issuance discounts recognized in the consolidated statement of operations as interest expense each period in which such instruments are outstanding. The Company records debt issuance costs related to a recognized debt liability in the consolidated balance sheets as a direct deduction from the carrying amount of that debt liability 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. If the Company issues shares to discharge the liability, the debt obligation is derecognized and common stock and additional paid-in capital are recognized upon the issuance of those shares. The 2017 Notes could only be settled in ADSs upon conversion. The terms of the 2017 Notes also allowed for repurchase in cash by the Company at the option of the holders as well as redemption by the Company for cash at specified times. The conversion feature in the 2017 Notes qualified for the exception from derivative accounting in accordance with ASC 815-40 and was therefore accounted for as part of the debt host. The conversion feature in the 2017 Notes was evaluated on a quarterly basis to determine if it still received an exception from derivative accounting in accordance with ASC 815-40. The 2017 Notes were recognized at par of $30.0 million. The Company also recognized a $1.2 million discount related to placement agent fees and offering expenses. This discount was amortized through interest expense through the date of mandatory exchange. See Note 7—Debt for further discussion.
Stock-Based Compensation | 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. The Company estimates the level of forfeitures expected to occur based on its historical data and records compensation cost only for those awards that are ultimately expected to vest. See Note 11—Stock Incentive Plans and Stock-Based Compensation for further discussion.
Concentration of Credit Risk | 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. Three customers individually accounted for 10% or more of the Company’s gross product sales. Customers A, B, and C accounted for 31%, 30%, and 27%, respectively, of gross product sales for the year ended December 31, 2018 and represented 26%, 24%, and 39%, respectively, of the gross accounts receivable balance as of December 31, 2018. Customers A, B, and C accounted for 27%, 33%, and 28%, respectively, of gross product sales for the year ended December 31, 2017 and represented 27%, 21%, and 41%, respectively, of the gross accounts receivable balance as of December 31, 2017. The Company has not experienced any significant write-offs of its accounts receivable.
Concentration of Suppliers | Concentration of Suppliers The Company has contractual freedom to source the API for Vascepa and to procure other services supporting its supply chain 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 suppliers. The Company cannot provide assurance that its efforts to procure uninterrupted supply of Vascepa to meet market demand will continue to be successful or that it will be able to renew current supply agreements on favorable terms or at all. Significant alteration to or termination of the Company’s current 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 multiple independent FDA-approved API manufacturers and several independent FDA-approved API encapsulators and packagers for Vascepa manufacturing. Each of these companies has qualified and validated 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 manufacture Vascepa will remain qualified to do so to its specifications or that these and any future suppliers will have the manufacturing capacity to meet anticipated demand for Vascepa.
Foreign Currency | 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.
Fair Value of Financial Instruments | 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, 2018 and 2017 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, 2018 |
In thousands |  | Total |  |  | Level 1 |  |  | Level 2 |  |  | Level 3 |
Asset: |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Cash equivalents—money markets |  | $ | 9,880 |  |  | $ | 9,880 |  |  | $ | — |  |  | $ | — |
|  | December 31, 2017 |
In thousands |  | Total |  |  | Level 1 |  |  | Level 2 |  |  | Level 3 |
Asset: |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Cash equivalents—money markets |  | $ | 9,317 |  |  | $ | 9,317 |  |  | $ | — |  |  | $ | — |
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, 2018 and 2017 are as follows:
|  | December 31, 2018 |  |  | December 31, 2017 |
In thousands |  | Carrying Value |  |  | Estimated Fair Value |  |  | Carrying Value |  |  | Estimated Fair Value |
Current portion of long-term debt from royalty-bearing instrument, net of accrued interest |  | $ | 33,602 |  |  |  |  |  |  | $ | 21,569 |  |  |  |  |
Long-term debt from royalty-bearing instrument |  |  | 46,108 |  |  |  |  |  |  |  | 70,834 |  |  |  |  |
Total long-term debt from royalty-bearing instrument |  | $ | 79,710 |  |  | $ | 78,600 |  |  | $ | 92,403 |  |  | $ | 88,000 |
2017 Notes |  |  | — |  |  |  | — |  |  |  | 28,992 |  |  |  | 38,200 |
The estimated fair value of the long-term debt from royalty-bearing instrument is calculated utilizing the same Level 3 inputs utilized in valuing the related derivative liability (see Derivative Liabilities below). The estimated fair value of the 2017 Notes was calculated based on Level 1 quoted bond prices or, in the absence of quoted bond prices, was calculated using a Level 3 binomial model. The carrying value of the long-term debt from royalty-bearing instrument as of both December 31, 2018 and 2017 did not include a debt discount as it had been fully amortized. The carrying value of the 2017 Notes as of December 31, 2018 and December 31, 2017 included a debt discount of nil and $1.0 million, respectively, which was being amortized as non-cash interest expense over the then expected term of the 2017 Notes, through the first optional put date in January 2022.
Derivative Liabilities | Derivative Liabilities Derivative financial liabilities are recorded at fair value, with gains and losses arising for changes in fair value recognized in the consolidated 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. Long-Term Debt Redemption Feature The Company’s December 2012 royalty-bearing instrument financing arrangement (discussed in Note 7—Debt) contains a redemption feature whereby, upon a change of control, the Company would be required to repay $150.0 million, less any previously repaid amount. The Company determined this redemption feature to be an embedded derivative, which is carried at fair value and is classified as Level 3 in the fair value hierarchy due to the use of significant unobservable inputs. The fair value of the embedded derivative was calculated using a probability-weighted model incorporating management estimates of future revenues and for a potential change in control, and by determining the fair value of the debt with and without the change in control provision included. The difference between the two was determined to be the fair value of the embedded derivative. The fair value of this derivative liability is remeasured at each reporting period, with changes in fair value recognized in the consolidated statement of operations. As of December 31, 2018, the fair value of the derivative was determined to be nil, and the debt was valued by comparing the debt issues of similar companies with (i) remaining terms of between 1.3 and 4.0 years, (ii) coupon rates of between 5.4% and 10.8% and (iii) market yields of between 6.7% and 15.8%. As of December 31, 2017, 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 similar companies with (i) remaining terms of between 2.3 and 4.3 years, (ii) coupon rates of between 5.8% and 10.8% and (iii) market yields of between 10.2% and 18.4%. As such, the Company recognized no gain on change in fair value of derivative liability for the year ended December 31, 2018 and 2017. 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 to the carrying value of such liabilities.
Segment and Geographical Information | Segment and Geographical Information Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated on a regular basis by the chief operating decision-maker, or decision-making group, in deciding how to allocate resources to an individual segment and in assessing performance of the segment. The Company currently operates in one business segment, which is the development and commercialization of Vascepa. A single management 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 Pronouncements | Recent Accounting Pronouncements From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board, or FASB, and are early adopted by the Company or adopted as of the specified effective date. In May 2014, the FASB issued Accounting Standards Update (“ASU”), No. 2014-09, which amends the guidance for accounting for revenue from contracts with customers. This ASU supersedes the revenue recognition requirements in Accounting Standards Codification (“ASC”) Topic 605, Revenue Recognition, and creates a new Topic 606, Revenue from Contracts with Customers. In 2015 and 2016, the FASB issued additional ASUs related to Topic 606 that delayed the effective date of the guidance and clarified various aspects of the new revenue guidance, including principal versus agent considerations, identifying performance obligations, and licensing, and they include other improvements and practical expedients. The Company adopted this standard effective January 1, 2018 using the modified retrospective transition method. The Company, as a result of adopting Topic 606 on January 1, 2018, has adjusted its opening retained earnings and deferred revenue balances by $0.2 million. The adjustment relates solely to the Company’s licensing revenues and the timing over which certain non-refundable upfront and milestone payments received from Eddingpharm (Asia) Macao Commercial Offshore Limited and HLS Therapeutics Inc. are recognized under Topic 606. No practical expedients associated with the adoption of Topic 606 were applied. In May 2017, the FASB issued ASU No.2017-09, Compensation—Stock Compensation: Scope of Modification Accounting. The amendments in ASU No. 2017-09 provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. The Company adopted this standard effective January 1, 2018 and, in accordance with the ASU, will apply it prospectively. The Company does not expect it to have a material impact on the Company’s consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-01, Clarifying the Definition of a Business. The standard clarifies the definition of a business when evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. Under the provisions of this new standard, it is expected that more transactions will be accounted for as asset acquisitions rather than business acquisitions. The Company adopted this standard effective January 1, 2018 and, in accordance with the ASU, will apply it prospectively. The Company does not expect it to have a material impact on the Company’s consolidated financial statements. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory, which requires the recognition of income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs. The Company adopted this standard effective January 1, 2018, which had no impact on the Company’s consolidated financial statements. 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 related to eight specific issues are presented and classified in the statement of cash flows. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, which requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The Company adopted this standard effective January 1, 2018 and, in accordance with the ASUs, applied them using a retrospective transition method to each period presented. Adoption of these ASUs did not have a material impact on the Company’s consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The new guidance is intended to improve the recognition and measurement of financial instruments by requiring separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables) within the 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 the balance 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 be measured at fair value with changes in fair value recognized in net income, and requiring a reporting organization to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk (also referred to as “own credit”) when the organization has elected to measure the liability at fair value in accordance with the fair value option for financial instruments, among others. In February 2018, the FASB issued ASU No. 2018-03, Technical Corrections and Improvements to Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities, which is intended to clarify certain aspects of the guidance issued in ASU 2016-01. The Company adopted these standards effective January 1, 2018, which had no impact on the Company’s consolidated financial statements. The Company also considered the following recent accounting pronouncements which were not yet adopted as of December 31, 2018: In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement, which eliminates, adds and modifies certain disclosure requirements for fair value measurements, including eliminating the requirement to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, and requiring disclosure of the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. The new guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption, either of the entire standard or only the provisions that eliminate or modify requirements, is permitted. The Company has evaluated the disclosure requirements of this standard and does not expect it to have a material impact on the Company’s consolidated financial statements. In June 2018, the FASB issued ASU No. 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, which is intended to simplify the accounting for share-based payments to nonemployees by aligning it with the accounting for share-based payments to employees, with certain exceptions. The new guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The Company has evaluated the accounting, transition and disclosure requirements of this standard and does not expect it to have a material impact on the Company’s consolidated financial statements. 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 lease liability 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 lease payments. The asset will be based on the liability, subject to adjustment, such as for initial direct costs. Under the new guidance, lessor accounting is largely unchanged but certain targeted improvements were made to align, where necessary, lessor accounting with the lessee accounting model and Topic 606, Revenue from Contracts with Customers. The new lease guidance also simplified the accounting for sale and leaseback transactions primarily because lessees must recognize lease assets and lease liabilities and therefore, will no longer be provided with a source of off-balance sheet financing. In July 2018, the FASB issued ASU No. 2018-10, which provides narrow amendments to ASU No. 2016-02 to clarify how to apply the rate implicit in the lease, impairment of the net investment in the lease, lessee reassessment of lease classification, variable payments that depend on an index or rate and certain transition adjustments. In July 2018, the FASB also issued ASU No. 2018-11, which provides targeted improvements to ASU No. 2016-02 to provide entities the transition option to not apply the standard in the comparative periods presented in the year of adoption. The Company will adopt the new standard effective January 1, 2019 using the modified retrospective transition method and elect to not apply the standard in the comparative periods presented in the year of adoption. The Company’s assessment of adopting ASU No. 2016-02 consisted of a review of contracts, discussions with key stakeholders and a cataloging of potential impacts on its internal controls, policies and operations. The adoption will not have a material impact on the Company’s consolidated financial statements as of the effective date. As further described in Note 17—Subsequent Events, on February 5, 2019 the Company entered into a lease for new office space. The Company is currently evaluating the impact of this lease to the Company’s consolidated financial statements under ASC 842. The Company believes that the impact of other recently issued but not yet adopted accounting pronouncements will not have a material impact on the Company’s consolidated financial position, results of operations, and cash flows, or do not apply to the Company’s operations.
