Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation We have prepared the accompanying unaudited consolidated condensed financial statements in accordance with the requirements of Form 10-Q and, therefore, they do not include all information and footnotes necessary for a fair presentation of financial position, results of operations, and cash flows in conformity with accounting principles generally accepted in the United States (GAAP). In our opinion, the consolidated condensed financial statements reflect all adjustments (including those that are normal and recurring) that are necessary for a fair presentation of the results of operations for the periods shown. In preparing financial statements in conformity with GAAP, we must make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses, and related disclosures at the date of the financial statements and during the reporting period. Actual results could differ from those estimates. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with our consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2022. We issued our financial statements by filing them with the Securities and Exchange Commission and have evaluated subsequent events up to the time of the filing of this Quarterly Report on Form 10-Q. All per-share amounts, unless otherwise noted in the footnotes, are presented on a diluted basis; that is, based on the weighted-average number of common shares outstanding plus the effect of incremental shares from our stock-based compensation programs. We operate as a single operating segment engaged in the discovery, development, manufacturing, marketing, and sales of pharmaceutical products worldwide. A global research and development organization and a supply chain organization are responsible for the discovery, development, manufacturing, and supply of our products. Regional commercial organizations market, distribute, and sell the products. The business is also supported by global corporate staff functions. Our determination that we operate as a single segment is consistent with the financial information regularly reviewed by the chief operating decision maker for purposes of evaluating performance, allocating resources, setting incentive compensation targets, and planning and forecasting for future periods. Research and Development Expenses and Acquired In-Process Research and Development (IPR&D) Research and development costs are expensed as incurred. Research and development costs consist of expenses incurred in performing research and development activities, including but not limited to, compensation and benefits, facilities and overhead expense, clinical trial expense, and fees paid to contract research organizations. Acquired IPR&D includes the initial costs and development milestones incurred related to externally developed IPR&D projects, acquired directly in a transaction other than a business combination, that do not have an alternative future use. Development milestones are milestone payment obligations that are incurred prior to regulatory approval of the compound and are expensed when the event triggering an obligation to pay the milestone occurs. Reclassifications Certain reclassifications have been made to prior periods in the consolidated condensed financial statements and accompanying notes to conform with the current presentation. Development milestone payments related to externally developed IPR&D projects, acquired directly in a transaction other than a business combination, were previously included in cash flows from operating activities in the consolidated condensed statements of cash flows and are now included in purchases of IPR&D in cash flows from investing activities. The reclassification resulted in an increase to net cash provided by operating activities and net cash used in investing activities of $386.4 million for the six months ended June 30, 2022.
