Accounting Policies [Abstract] |
ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The accompanying Condensed Consolidated Financial Statements and related Notes to Condensed Consolidated Financial Statements of Gilead Sciences, Inc. (“Gilead,” “we,” “our” or “us”) should be read in conjunction with the audited Consolidated Financial Statements and the related notes thereto for the year ended December 31, 2021, included in our Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission. There have been no material changes to our organization or summary of significant accounting policies as disclosed in that filing except for our classification of expenses related to development milestones and other collaboration payments made prior to regulatory approval of a developed product. Beginning in the second quarter of 2022, we reclassified such expenses from Research and development expenses to Acquired in-process research and development expenses in the Condensed Consolidated Statements of Income. Concurrently, we reclassified the cash payments related to these expenses from Other to Acquisitions, including in-process research and development, net of cash acquired within Investing Activities in the Condensed Consolidated Statements of Cash Flows. We believe this presentation assists users of the financial statements to better understand the total costs incurred to acquire in-process research and development (“IPR&D”) projects. Prior periods have been revised to reflect this classification, resulting in a reduction of previously-reported Research and development expenses of $46 million and $93 million for the three and nine months ended September 30, 2021, respectively, and $8 million for the three months ended March 31, 2022. These interim financial statements have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and include all adjustments consisting of normal recurring adjustments that the management of Gilead believes are necessary for a fair presentation of the periods presented and are not necessarily indicative of results expected for the full fiscal year or for any subsequent interim period. Certain amounts and percentages in these Condensed Consolidated Financial Statements and accompanying notes may not sum or recalculate due to rounding.
