Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Implementation of New Financial Accounting Standard	Basis of Presentation and Implementation of New Financial Accounting Standard 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, 2021. We issue 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. Certain reclassifications have been made to prior periods in the consolidated condensed financial statements and accompanying notes to conform with the current presentation. 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) and Development Milestones 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 and development milestones include the initial costs of externally developed IPR&D projects, acquired directly in a transaction other than a business combination, that do not have an alternative future use. Additionally, milestone payment obligations related to these transactions that are incurred prior to regulatory approval of the compound are expensed when the event triggering an obligation to pay the milestone occurs. Implementation of New Financial Accounting Standard Accounting Standards Update 2021-01, Reference Rate Reform, provides for temporary optional expedients and exceptions in applying current GAAP to contracts, hedging relationships, and other transactions affected by the transition from the use of the London Interbank Offered Rate (LIBOR) to an alternative reference rate. The standard is currently applicable to contracts entered into before January 1, 2023. We adopted the standard in the first quarter of 2022. The adoption did not have a material impact on our consolidated condensed financial statements.
