Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of Consolidation | Basis of Consolidation The condensed consolidated financial statements include the accounts of Exelixis and those of our wholly-owned subsidiaries. These entities’ functional currency is the U.S. dollar. All intercompany balances and transactions have been eliminated.
Basis of Presentation | Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S.”) for interim financial information and pursuant to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements. In our opinion, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation of the results of operations and cash flows for the periods presented have been included.
Fiscal Period | We have adopted a 52- or 53-week fiscal year policy that generally ends on the Friday closest to December 31st. Fiscal year 2017 will end on December 29, 2017 and fiscal year 2016 ended on December 30, 2016. For convenience, references in this report as of and for the fiscal periods ended March 31, 2017 and April 1, 2016, and as of and for the fiscal years ended December 29, 2017 and December 30, 2016, are indicated as being as of and for the periods ended March 31, 2017 and March 31, 2016, and the years ended December 31, 2017 and December 31, 2016, respectively.
Use of Estimates | Use of Estimates The preparation of our condensed consolidated financial statements conforms to accounting principles generally accepted in the U.S. which requires management to make judgments, estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosures. On an ongoing basis, management evaluates its estimates including, but not limited to, those related to revenue recognition, including deductions from revenues (such as rebates, chargebacks, sales returns and sales allowances), the period of performance, identification of deliverables and evaluation of milestones with respect to our collaborations, the amounts of revenues and expenses under our profit and loss sharing agreement, recoverability of inventory, certain accrued liabilities including accrued clinical trial liability, and stock-based compensation. We base our estimates on historical experience and on various other market-specific and other relevant assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ materially from those estimates.
Correction of an Immaterial Error | Correction of an Immaterial Error During the third quarter of 2016, we identified errors in the Consolidated Balance Sheets and Consolidated Statements of Operations, Comprehensive Loss and Cash Flows for 2015, 2014, 2013, and 2012, and in the unaudited interim Condensed Consolidated Balance Sheets and Condensed Consolidated Statements of Operations, Comprehensive Loss and Cash Flows for all prior interim fiscal periods from September 30, 2012 through June 30, 2016. Specifically, in 2012 we incorrectly calculated 1) the allocation between Additional paid-in capital and Convertible notes of the $287.5 million aggregate principal amount from our 4.25% Convertible Senior Subordinated Notes due 2019 (“2019 Notes”); and 2) the amortization of the debt discount associated with the 2019 Notes during 2012 and all subsequent periods. Having evaluated the materiality of these errors from a quantitative and qualitative perspective, management has concluded that although the accumulation of these errors was significant to the three and nine months ended September 30, 2016, the correction of these errors would not be material to any individual prior period, and did not have an effect on the trend of financial results, taking into account the requirements of the SEC Staff Accounting Bulletin No. 99, Materiality and Staff Accounting Bulletin No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements. Because management has concluded that these errors are not material, we will correct them prospectively when the consolidated balance sheets, statements of operations, comprehensive loss and cash flows for such periods are included in future filings. Following are the amounts (in thousands, except per share amounts) that should have been reported for the affected line items of the statement of operations, statement of comprehensive loss and statement of cash flows:
| Three Months Ended March 31, 2016
Statement of Operations: |
Interest expense, overstated by $2,124 for the three months ended March 31, 2016 | $ | (10,290 | )
Total other expense, net, overstated by $2,124 for the three months ended March 31, 2016 | $ | (10,088 | )
Net loss, overstated by $2,124 for the three months ended March 31, 2016 | $ | (59,223 | )
Net loss per share, basic and diluted, overstated by $0.01 for the three months ended March 31, 2016 | $ | (0.26 | )
Statements of Comprehensive Loss: |
Comprehensive loss, overstated by $2,124 for the three months ended March 31, 2016 | $ | (59,033 | )
Statements of Cash Flows (1): |
Net loss, overstated by $2,124 for the three months ended March 31, 2016 | $ | (59,223 | )
Accretion of debt discount and debt issuance costs, overstated by $2,124 for the three months ended March 31, 2016 | $ | 3,161 |
____________________
(1) | The error did not impact our net cash provided by or used in operating activities, financing activities or investing activities for any of the periods presented.
These errors did not affect any other caption or total in our unaudited condensed or annual consolidated financial statements as of and for the three months ended March 31, 2016. See “Note 1 - Organization and Summary of Significant Accounting Policies” to our Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2016 for the amounts of the corrections and the amounts that should have been reported for 2015, 2014, 2013, and 2012 in the affected line items of the statements of operations, statements of comprehensive loss and statements of cash flows.
Reclassifications | Reclassifications Certain prior period amounts in the condensed consolidated financial statements have been reclassified to conform to current period presentation. We reclassified $1.8 million in accrued product sales discounts payable to our customers as of December 31, 2016 from Other current liabilities to Trade and other receivables in the accompanying Condensed Consolidated Balance Sheets. We have also reclassified the related balances between the Changes in assets and liabilities line items in the accompanying Condensed Consolidated Statements of Cash Flows for the three months ended March 31, 2016 to conform the presentation of those line items to the corresponding presentation of assets and liabilities in our accompanying Condensed Consolidated Balance Sheets.
Segment Information | Segment Information We operate as a single reportable segment.
Stock-Based Compensation | Stock-Based Compensation In January 2017, we adopted Accounting Standards Update (“ASU”) No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, (“ASU 2016-09”). ASU 2016-09 is aimed at the simplification of several aspects of the accounting for employee share-based payment transactions, including accounting for forfeitures, income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Pursuant to the adoption of ASU 2016-09, we have made an election to record forfeitures when they occur. Previously, stock-based compensation was based on the number of awards expected to vest after considering estimated forfeitures. The change in accounting principle with regards to forfeitures was adopted using a modified retrospective approach, and no prior periods were restated as a result of this change in accounting principle, with a cumulative adjustment of $0.3 million to accumulated deficit and additional paid-in-capital as of January 1, 2017. As a result of the adoption of ASU 2016-09, we also recorded an increase to the federal and state net operating losses of $56.9 million for excess tax benefits previously not included. The resulting increase to the deferred tax assets of approximately $21.2 million is offset by a corresponding increase to the valuation allowance, resulting in a net impact of zero on our income tax expense and our Condensed Consolidated Balance Sheets. ASU 2016-09 also requires that cash paid to taxing authorities when directly withholding shares for tax withholding purposes should be classified as a financing activity. Previously, we classified such payments as operating cash flows. The change in accounting principle with regards to such cash flows was adopted using a retrospective approach. Accordingly, we reclassified $1.9 million in our Condensed Consolidated Statement of Cash Flows for the three months ended March 31, 2016 to reflect a $1.9 million increase in Cash provided by operating activities and a corresponding increase to Cash used in financing activities.
Recent Accounting Pronouncements | Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”). In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which delays the effective date of ASU 2014-09 by one year. ASU 2014-09, as amended, becomes effective for us in the first quarter of fiscal year 2018, but allows us to adopt the standard one year earlier. We will adopt ASU 2014-09 in the first quarter of fiscal year 2018. ASU 2014-09 also permits two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (the modified retrospective method). We will adopt ASU 2014-09 using the modified retrospective method. The core principle of ASU 2014-09 is that an entity should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition process than required under existing U.S. generally accepted accounting pronouncements. We do not expect that ASU 2014-09 will have a material impact on the recognition of revenue from product sales. We are still in the process of evaluating the effect that this guidance will have on revenue recognition from our collaboration agreements such as our arrangements with Ipsen Pharma SAS (“Ipsen”), Takeda Pharmaceutical Company Ltd. (“Takeda”) and Genentech. We expect our evaluation to be completed by the end of the second quarter of 2017.
