Accounting Policies [Abstract] |
Basis of Presentation and Summary of Significant Accounting Policies | Basis of Presentation and Summary of Significant Accounting Policies Basis of Presentation: The condensed consolidated financial statements included in this report are unaudited and have been prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“U.S. GAAP”) for interim financial reporting and U.S. Securities and Exchange Commission (“SEC”) regulations. The year-end condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. In the opinion of management, these financial statements include all adjustments, which are of a normal recurring nature, necessary for a fair statement of the financial position, results of operations, cash flows and the change in equity for the periods presented. The condensed consolidated financial statements for the three months ended March 31, 2022, should be read in conjunction with the consolidated financial statements and notes thereto of West Pharmaceutical Services, Inc. and its majority-owned subsidiaries (which may be referred to as “West,” the “Company,” “we,” “us” or “our”) appearing in our Annual Report on Form 10-K for the year ended December 31, 2021 (the “2021 Annual Report”). The results of operations for any interim period are not necessarily indicative of results for the full year. West has been actively monitoring the coronavirus (“COVID-19”) situation and its impact globally. Our production facilities continue to operate as they had prior to the COVID-19 pandemic, other than for enhanced safety measures intended to prevent the spread of the virus. The remote working arrangements and travel restrictions imposed by various governments had limited impact on our ability to maintain operations, as our manufacturing operations have generally been exempted from stay-at-home orders.
