Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Basis of Presentation The accompanying financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). The consolidated financial statements include our accounts and our wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, expenses and revenue and related disclosures. On an ongoing basis, we evaluate our estimates, including estimates related to revenue, intangible asset impairment, clinical trial accruals and share-based compensation expense. We base our estimates on historical experience and other market-specific or other relevant assumptions that we believe to be reasonable under the circumstances. Actual results may differ from those estimates or assumptions. Revenue Recognition We are currently approved to sell Rubraca in the United States market. We distribute our product principally through a limited number of specialty distributor and specialty pharmacy providers, collectively, our customers. Our customers subsequently sell our products to patients and health care providers. Separately, we have arrangements with certain payors and other third-parties that provide for government-mandated and privately-negotiated rebates, chargebacks and discounts. Revenues from product sales are recognized when persuasive evidence of an arrangement exists, delivery has occurred and title of the product and associated risk of loss has passed to the customer, the price is fixed or determinable, collection from the customer has been reasonably assured and all performance obligations have been met and returns and allowances can be reasonably estimated. Product sales are recorded net of estimated rebates, chargebacks, discounts and other deductions as well as estimated product returns. Estimating rebates, chargebacks, discounts, product returns and other deductions requires significant judgments about future events and uncertainties, and requires us to rely heavily on assumptions, as well as historical experience. We only recognize revenue on product sales once the product is sold to the patient or healthcare provider by the specialty distributor or specialty pharmacy provider, therefore reducing the significance of estimates made for product returns. For the year ended December 31, 2017, we recognized $55.5 million of product revenue. Based on our policy to expense costs associated with the manufacture of our products prior to regulatory approval, certain of the costs of Rubraca units recognized as revenue during the year ended December 31, 2017 were expensed prior to the December 19, 2016 FDA approval, and a minimal amount is included in cost of sales during the current period. We expect cost of sales to increase in relation to product revenues as we deplete these inventories. The majority of products sales were of pre-commercialization inventory in 2017. Product revenue from each of our customers who individually accounted for 10% or more of total revenues consisted of the following: December 31, 2017 Customer A 35% Customer B 27% Customer C 12% Customer D 10% Effective January 1, 2018, we adopted ASC 606, the new revenue recognition standard, using the modified retrospective method. For a complete discussion of this adoption and the accounting for net product revenue, see the Recently Issued Accounting Standards section below and Note 11, Revenue Recognition . Fair Value of Financial Instruments Cash, cash equivalents, available-for-sale securities and contingent purchase consideration are carried at fair value. Financial instruments, including other current assets and accounts payable, are carried at cost, which approximates fair value given their short-term nature (see Note 4, Fair Value Measurements ). Cash, Cash Equivalents and Available-for-Sale Securities We consider all highly liquid investments with original maturities at the date of purchase of three months or less to be cash equivalents. Cash and cash equivalents include bank demand deposits and money market funds that invest primarily in certificate of deposits, commercial paper and U.S. government and U.S. government agency obligations. Marketable securities are considered to be available-for-sale securities and consist of U.S. treasury securities. Available-for-sale securities are reported at fair value on the Consolidated Balance Sheets and unrealized gains and losses are included in accumulated other comprehensive loss on the Consolidated Balance Sheets. Realized gains and losses, amortization of premiums and discounts and interest and dividends earned are included in other income (expense) on the Consolidated Statements of Operations and Comprehensive Loss. The cost of investments for purposes of computing realized and unrealized gains and losses is based on the specific identification method. Investments with maturities beyond one year are classified as short-term based on our intent to fund current operations with these securities or to make them available for current operations. A decline in the market value of a security below its cost that is deemed to be other than temporary is charged to earnings and results in the establishment of a new cost basis for the security. Factors evaluated to determine if an investment is other-than-temporarily impaired include significant deterioration in earnings performance, credit rating, asset quality or business prospects of the issuer; adverse changes in the general market conditions in which the issuer operates; and our intent and ability to hold the security until an anticipated recovery in value occurs. Accounts Receivable As of December 31, 2017 and 2016, we had no allowance for doubtful accounts. We provide an allowance for doubtful accounts based on experience and specifically identified risks. Accounts receivable are carried at fair value and charged off against the allowance for doubtful accounts when we determine that recovery is unlikely and we cease collection efforts. Property and Equipment Property and equipment are stated at cost, less accumulated depreciation. Property and equipment are depreciated using the straight-line method over the estimated useful lives of the assets. Equipment purchased for use in manufacturing and clinical trials is evaluated to determine whether the equipment is solely beneficial for a drug candidate in the development stage or whether it has an alternative use. Equipment with an alternative use is capitalized. Leasehold improvements are amortized over the economic life of the asset or the lease term, whichever is shorter. Maintenance and repairs are expensed as incurred. The estimated useful lives of our capitalized assets are as follows: Estimated Useful Life Computer hardware and software 3 to 5 years Leasehold improvements 6 years Laboratory, manufacturing and office equipment 5 to 7 years Furniture and fixtures 10 years Long-Lived Assets We review long-lived assets for impairment when events or changes in circumstances indicate that the carrying value of the assets may not be recoverable. Recoverability is measured by comparison of the assets’ book value to future net undiscounted cash flows that the assets are expected to generate. If the carrying value of the assets exceed their future net undiscounted cash flows, an impairment charge is recognized for the amount by which the carrying value of the assets exceeds the fair value of the assets. Intangible Assets, Net Definite-lived intangible assets related to capitalized milestones under license agreements are amortized on a straight-line basis over their remaining useful lives, which are estimated to be the remaining patent life. If our estimate of the product’s useful life is shorter than the remaining patent life, then a shorter period is used. Amortization expense is recorded as a component of cost of sales on the Consolidated Statements of Operations and Comprehensive Loss. Intangible acquired in-process research and development (“IPR&D”) assets were established as part of the acquisition of Ethical Oncology Science, S.p.A. (“EOS”) in November 2013 and were not amortized. Intangible assets are evaluated for impairment at least annually in the fourth quarter or more frequently if impairment indicators exist. Events that could result in an impairment, or trigger an interim impairment assessment, include the decision to discontinue the development of a drug, the receipt of additional clinical or nonclinical data regarding our drug candidate or a potentially competitive drug candidate, changes in the clinical development program for a drug candidate, or new information regarding potential sales for the drug. In connection with any impairment assessment, the fair value of the intangible assets as of the date of assessment is compared to the carrying value of the intangible asset. Impairment losses are recognized if the carrying value of an intangible asset is both not recoverable and exceeds its fair value. During the second quarter of 2016, we recorded a $104.5 million impairment charge to the IPR&D intangible assets, reducing the remaining carrying value to zero (see Note 6, Intangible Assets and Goodwill ). Previously, the Company recorded an $89.6 million impairment charge to the IPR&D intangible assets during the fourth quarter of 2015. Goodwill Goodwill represents the excess of the purchase price over the fair value of net assets acquired in a business combination accounted for under the acquisition method of accounting and is not amortized, but is subject to impairment testing at least annually in the fourth quarter or when a triggering event is identified that could indicate a potential impairment. We are organized as a single reporting unit and perform impairment testing by comparing the carrying value of the reporting unit to the fair value of the Company. Goodwill was recorded as a result of the EOS acquisition. Other Current Assets Other current assets are comprised of the following (in thousands): December 31, December 31, 2017 2016 Receivable from partners $ 9 $ 2,882 Prepaid insurance 1,926 1,234 Prepaid expenses - other 3,355 2,109 Receivable - other 2,023 364 Other 187 90 Total $ 7,500 $ 6,679 Other Accrued Expenses Other accrued expenses are comprised of the following (in thousands): December 31, December 31, 2017 2016 Accrued personnel costs $ 13,889 $ 15,850 Accrued interest payable 2,096 2,096 Income tax payable — 556 Accrued corporate legal fees and professional services 415 589 Accrued royalties 2,984 — Accrued sales deductions 1,008 — Payable to third party logistics provider 2,661 — Accrued expenses - other 2,830 396 Total $ 25,883 $ 19,487 Valuation of Contingent Consideration Resulting from a Business Combination Subsequent to the acquisition date, we re-measure contingent consideration arrangements at fair value each reporting period and record changes in fair value to change in fair value of contingent purchase consideration and foreign currency gains (losses) for changes in the foreign currency translation rate on the Consolidated Statements of Operations and Comprehensive Loss. Changes in fair value are primarily attributed to new information about the IPR&D assets, including changes in timeline and likelihood of success, and the passage of time. In the absence of new information, changes in fair value reflect only the passage of time. During the fourth quarter of 2015, we recorded a $26.9 million reduction in the fair value of the contingent purchase consideration liability due to a change in the estimated probability-weighted future discounted milestone payments, as well as the timing of such payments, for the lucitanib program. Then, during the second quarter of 2016, we recorded a $25.5 million reduction in the fair value of the contingent purchase consideration liability due to our and our development partner’s decision to discontinue the development of lucitanib for breast cancer. At December 31, 2017, the contingent purchase consideration liability recorded on the Consolidated Balance Sheets remained at zero due to the uncertainty of achieving any of the lucitanib regulatory milestones, and therefore the remote likelihood of future milestone payouts. Research and Development Expense Research and development costs are charged to expense as incurred and include, but are not limited to, salary and benefits, share-based compensation, clinical trial activities, drug development and manufacturing, companion diagnostic development and third-party service fees, including contract research organizations and investigative sites. During 2015, we completed the hiring of our U.S. sales and marketing and medical affairs organizations in preparation for the potential commercial launch of Rubraca. These costs were also included in research and development expense before the FDA approval of Rubraca. Costs for certain development activities, such as clinical trials, are recognized based on an evaluation of the progress to completion of specific tasks using data such as patient enrollment, clinical site activations or information provided to us by our vendors on their actual costs incurred. Payments for these activities are based on the terms of the individual arrangements, which may differ from the pattern of costs incurred and are reflected on the Consolidated Balance Sheets as prepaid or accrued research and development expenses. Acquired In-Process Research and Development Expense We have acquired and expect to continue to acquire the rights to develop and commercialize new drug candidates. The upfront payments to acquire a new drug compound, as well as subsequent milestone payments, are immediately expensed as acquired in-process research and development provided that the drug has not achieved regulatory approval for marketing and, absent obtaining such approval, has no alternative future use. Once regulatory approval is received, payments to acquire rights, and the related milestone payments, are capitalized and the amortization of such assets recorded to product cost of sales. Share-Based Compensation Expense Share-based compensation is recognized as expense for all share-based awards made to employees and directors and is based on estimated fair values. We determine equity-based compensation at the grant date using the Black-Scholes option pricing model. The value of the award that is ultimately expected to vest is recognized as expense on a straight-line basis over the requisite service period. Any changes to the estimated forfeiture rates are accounted for prospectively. Inventory Inventories are stated at the lower of cost or estimated net realizable value, on a first-in, first-out, or FIFO, basis. Prior to the regulatory approval of Rubraca, we incurred expenses for the manufacture of drug that could potentially be available to support the commercial launch of Rubraca. Until the first reporting period when regulatory approval has been received, we record all such costs as research and development expense. We periodically analyze our inventory levels, and write down inventory that has become obsolete, inventory that has a cost basis in excess of its estimated realizable value and/or inventory in excess of expected sales requirements as cost of product revenues. Expired inventory would be disposed of and the related costs would be written off as cost of product revenues. The active pharma ceutical ingredient in Rubraca is currently produced by a single supplier. At December 31, 2017, deposit on inventory on the Consolidated Balance Sheets is a cash deposit of $20.5 million made to a manufacturer for the purchase of inventory which we expect to be converted to finished goods within the next twelve months. Concentration of Credit Risk Financial instruments that potentially subject us to concentrations of credit risk are primarily cash, cash equivalents and available-for-sale securities. We maintain our cash and cash equivalent balances in the form of money market accounts with financial institutions that we believe are creditworthy. Available-for-sale securities are invested in accordance with our investment policy. The investment policy includes guidelines on the quality of the institutions and financial instruments and defines allowable investments that we believe minimizes the exposure to concentration of credit risk. We have no financial instruments with off-balance sheet risk of accounting loss. Foreign Currency The assets and liabilities of our foreign operations are translated into U.S. dollars at current exchange rates and the results of operations are translated at the average exchange rates for the reported periods. The resulting translation adjustments are included in accumulated other comprehensive loss on the Consolidated Balance Sheets. Transactions denominated in currencies other than the functional currency are recorded based on exchange rates at the time such transactions arise. Transaction gains and losses are recorded to foreign currency gains (losses) on the Consolidated Statements of Operations and Comprehensive Loss. As of December 31, 2017 and 2016, approximately 1% of our total liabilities were denominated in currencies other than the functional currency. Income Taxes We account for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases using enacted tax rates in effect for the year in which the differences are expected to affect taxable income. Tax benefits are recognized when it is more likely than not that a tax position will be sustained during an audit. Deferred tax assets are reduced by a valuation allowance if current evidence indicates that it is considered more likely than not that these benefits will not be realized. Recently Adopted Accounting Standards In March 2016, the FASB issued Accounting Standards Update No. 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting" (ASU 2016-09). ASU 2016-09 simplifies how several aspects of share-based payments are accounted for and presented in the financial statements. ASU 2016-09 is effective for public companies for annual reporting periods beginning after December 15, 2016. We adopted this ASU in the first quarter of 2017. We had excess tax benefits for which a benefit could not be previously recognized of approximately $18.2 million. Upon adoption the balance of the unrecognized excess tax benefits were reversed with the impact recorded to retained earnings including any change to the valuation allowance as a result of the adoption. Due to the full valuation allowance on the U.S. deferred tax assets, there is no impact to the financial statements as a result of this adoption. Recently Issued Accounting Standards In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014-09, “Revenue from Contracts with Customers” and has subsequently issued several supplemental and/or clarifying ASUs (collectively, “ASC 606”). ASC 606 prescribes a single common revenue standard that replaces most existing U.S. GAAP revenue recognition guidance. ASC 606 is intended to provide a more consistent interpretation and application of the principles outlined in the standard across filers in multiple industries and within the same industries compared to current practices, which should improve comparability. Adoption of ASC 606 is required for annual and interim periods beginning after December 15, 2017. Upon adoption, we must elect to adopt either retrospectively to each prior reporting period presented or use the modified retrospective transition method with the cumulative effect of initial adoption recognized at the date of initial application. We have elected to apply the new standard using the modified retrospective method upon its adoption date on January 1, 2018. Under ASC 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 ASC 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. ASC 606 also impacts certain other areas, such as the accounting for costs to obtain or fulfill a contract. The standard also requires disclosure of the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. We have examined our revenue recognition policy specific to revenue streams from representative contracts governing product sales from Rubraca and have come to conclusions on the impact of the new standard using the 5-step process prescribed by ASC 606. We have reviewed a representative sample of contracts, including our collaboration agreements with Servier and Bristol-Myers Squibb discussed in Note 13, License Agreements , and determined the potential impact to our accounting policies, financial controls and operations. Our conclusions include recognizing revenue on product sales once the product is sold to the specialty distributor and specialty pharmacy providers. Currently, we anticipate the effects of adoption to be as described in Note 11, Revenue Recognition . In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842),” which requires lessees to recognize assets and liabilities for the rights and obligations created by most leases on their balance sheet. The guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted. We plan to adopt on January 1, 2019. ASU 2016-02 requires modified retrospective adoption for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. We are currently evaluating the impact the standard may have on our consolidated financial statements and related disclosures. In January 2017, the FASB issued ASU No. 2017-01, “Clarifying the Definition of a Business,” which clarifies the definition of a business in ASC 805. The guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early application is permitted. We adopted this standard on January 1, 2018 and the adoption resulted in no change to our consolidated financial statements and related disclosures. In May 2017, the FASB issued ASU 2017-09, “Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting”, which amends the scope of modification accounting for share-based payment arrangements. The ASU provides guidance on the types of changes to the terms or conditions of share-based payment awards to which we would be required to apply modification accounting under ASC 718. Specifically, we would not apply modification accounting if the fair value, vesting conditions, and classification of the awards are the same immediately before and after the modification. The guidance is effective for annual reporting periods, including interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted, including adoption in any interim period. We adopted this standard on January 1, 2018 and the adoption resulted in no change to our consolidated financial statements and related disclosures. |
