Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP” or “GAAP”) for interim financial information and in accordance with the requirements of Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements, and should be read in conjunction with the Company’s audited consolidated financial statements as of and for the fiscal year ended March 31, 2022 contained in the Company’s Annual Report on Form 10-K. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair statement have been included. Operating results for the three-month period ended July 1, 2022 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2023. Certain prior period amounts in the condensed consolidated financial statements, as well as in the Notes thereto, have been reclassified to conform to the current presentation. The first quarters for fiscal years 2023 and 2022 ended on July 1, 2022, which is comprised of 92 days in the period, and July 2, 2021, which is comprised of 93 days in the period, respectively. The accompanying unaudited condensed consolidated financial statements include the accounts of Flex and its majority-owned subsidiaries, after elimination of intercompany accounts and transactions. The Company consolidates its majority-owned subsidiaries and investments in entities in which the Company has a controlling interest. For the consolidated majority-owned subsidiaries in which the Company owns less than 100%, the Company recognizes a noncontrolling interest for the ownership of the noncontrolling owners. In all cases other than the redeemable noncontrolling interest in Nextracker, the associated noncontrolling owners' interest in the income or losses of these companies is not material to the Company's results of operations for all periods presented, and is classified as a component of Interest and other, net, in the condensed consolidated statements of operations. Noncontrolling interest that is redeemable upon the occurrence of conditions outside of the control of the Company is reported as temporary equity in the consolidated balance sheets. The amount of consolidated net income attributable to Flex Ltd. and to the redeemable noncontrolling interest is presented in the condensed consolidated statements of operations.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Estimates are used in accounting for, among other things: allowances for doubtful accounts; inventory write-downs; valuation allowances for deferred tax assets; uncertain tax positions; valuation and useful lives of long-lived assets including property, equipment, and intangible assets; valuation of goodwill; valuation of investments in privately-held companies; asset impairments; fair values of financial instruments, notes receivable and derivative instruments; restructuring charges; contingencies; warranty provisions; incremental borrowing rates in determining the present value of lease payments; accruals for potential price adjustments arising from customer contracts; fair values of assets obtained and liabilities assumed in business combinations; and the fair values of stock options and restricted share unit awards granted under the Company's stock-based compensation plans. Due to the COVID-19 pandemic and geopolitical conflicts (including the Russian invasion of Ukraine), there has been and will continue to be uncertainty and disruption in the global economy and financial markets. The Company has made estimates and assumptions taking into consideration certain possible impacts due to the COVID-19 pandemic and the Russian invasion of Ukraine. These estimates may change, as new events occur, and additional information is obtained. Actual results may differ from previously estimated amounts, and such differences may be material to the condensed consolidated financial statements. Estimates and assumptions are reviewed periodically, and the effects of revisions are reflected in the period they occur.
Recently Adopted Accounting Pronouncement	Recently Adopted Accounting Pronouncement In July 2021, the FASB issued ASU 2021-05 "Leases (Topic 842): Lessors - Certain Leases with Variable Lease Payments", which requires a lessor to classify a lease with variable lease payments that don’t depend on an index or a rate as an operating lease on the commencement date of the lease if specified criteria are met. The guidance is effective for the Company beginning in the first quarter of fiscal year 2023 with early adoption permitted. The Company adopted the guidance during the first quarter of fiscal year 2023 with an immaterial impact on its condensed consolidated financial statements.
