The Company and Summary of Significant Accounting Policies and Estimates	The Company and Summary of Significant Accounting Policies and Estimates The Company Logitech International S.A., together with its consolidated subsidiaries ("Logitech" or the "Company"), designs software-enabled hardware solutions that help businesses thrive and bring people together when working, creating, and gaming. As the point of connection between people and the digital world, the Company's mission is to extend human potential in work and play, in a way that is good for people and the planet. The Company sells its products to a broad range of international customers, including direct sales to retailers, e-tailers, businesses large and small and end consumers through the Company's e-commerce platform, and indirect sales to end customers through distributors. Logitech was founded in Switzerland in 1981 and Logitech International S.A. has been the parent holding company of Logitech since 1988. Logitech International S.A. is a Swiss holding company with its registered office in Hautemorges, Switzerland, and headquarters in Lausanne, Switzerland, which conducts its business through subsidiaries in the Americas, Europe, Middle East and Africa ("EMEA") and Asia Pacific. Shares of Logitech International S.A. are listed on both the SIX Swiss Exchange under the trading symbol LOGN and the Nasdaq Global Select Market under the trading symbol LOGI. Basis of Presentation The condensed consolidated financial statements include the accounts of Logitech and its subsidiaries. All intercompany balances and transactions have been eliminated. The condensed consolidated financial statements are presented in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") for interim financial information and therefore do not include all the information required by U.S. GAAP for complete financial statements. The condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements for the fiscal year ended March 31, 2025, included in the Company's Annual Report on Form 10-K filed with the Securities and Exchange Commission ("SEC") on May 23, 2025. In the opinion of management, these condensed consolidated financial statements include all adjustments, consisting of only normal and recurring adjustments, necessary and in all material aspects, for a fair statement of the results of operations, comprehensive income, financial position, cash flows and changes in shareholders' equity for the periods presented. Operating results for the three and six months ended September 30, 2025 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2026, or any future periods. Changes in Significant Accounting Policies There have been no material changes in the Company’s significant accounting policies during the three and six months ended September 30, 2025 compared with the significant accounting policies described in its Annual Report on Form 10-K for the fiscal year ended March 31, 2025. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make judgments, estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Management bases its estimates on historical experience and various other assumptions believed to be reasonable. Significant estimates and assumptions made by management involve the fair value of goodwill and intangible assets acquired from business acquisitions, pension obligations, accruals for customer incentives, cooperative marketing, and pricing programs and related breakage when appropriate, inventory valuation, share-based compensation expense, uncertain tax positions, and valuation allowances for deferred tax assets. Although these estimates are based on management’s best knowledge of current events and actions that may impact the Company in the future, actual results could differ materially from those estimates. Risks and Uncertainties Impacts of Macroeconomic and Geopolitical Conditions on the Company's Business In 2025, the United States introduced trade policy actions that have increased import tariffs across a wide range of countries at various rates, with certain exemptions. These tariff policies in the U.S. and responsive policies enacted in other countries are evolving. The incremental tariffs have had and may continue to have an adverse impact on the Company's results of operations. In addition, the Company's business has continued to be impacted by ongoing macroeconomic and geopolitical conditions. These conditions include inflation, interest rate and foreign currency fluctuations, uncertainty in consumer and enterprise demand, low economic growth in certain regions, changes in fiscal policies and geopolitical conflicts. The global and regional economic and political conditions, as well as changes in trade policies, have caused and may continue to cause volatility in demand for the Company's products as well as the cost of tariffs, materials and logistics, and transportation delays, and as a result have impacted and may continue to impact the pricing of the Company's products, product availability and the Company's results of operations.
