Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	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, 2016 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 presentation have been included. Operating results for the three-month period ended July 1, 2016 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2017. The first quarters for fiscal year 2017 and fiscal year 2016 ended on July 1, 2016, which is comprised of 92 days in the period, and June 26, 2015, which is comprised of 87 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. Noncontrolling interests are presented as a separate component of total shareholders' equity in the condensed consolidated balance sheets. The associated noncontrolling owners' interests are immaterial for all of the periods presented, and are included in interest and other, net in the condensed consolidated statements of operations. The Company has certain non-majority-owned equity investments in non-publicly traded companies that are accounted for using the equity method of accounting. The equity method of accounting is used when the Company has the ability to significantly influence the operating decisions of the issuer, or if the Company has an ownership percentage of a corporation equal to or generally greater than 20% but less than 50%, and for non-majority-owned investments in partnerships when generally greater than 5%. The equity in earnings (losses) of equity method investees are immaterial for all of the periods presented, and are included in interest and other, net in the condensed consolidated statements of operations.
Recently Adopted and Issued Accounting Pronouncements	Recently Adopted Accounting Pronouncement In March 2016, the Financial Accounting Standards Board ("FASB") issued new guidance intended to reduce the cost and complexity of the accounting for share-based payments. The new guidance simplifies various aspects of the accounting for share-based payments including income tax effects, withholding requirements and forfeitures. The Company elected to early adopt this new guidance during the three-month period ended July 1, 2016. The guidance eliminates additional paid in capital ("APIC") pools and requires companies to recognize all excess tax benefits and tax deficiencies in the income statement when the awards vest or are settled. It also addresses the presentation of excess tax benefits and employee taxes paid on the statement of cash flows. Prior to adoption, the Company elected to not deduct tax benefits for stock-based compensation awards on its tax returns, and accordingly, did not have any excess tax benefits or tax deficiencies upon adoption. The Company therefore determined that adoption of the new guidance had no impact on the condensed consolidated statement of operations and the condensed consolidated statement of cash flows. Further, the new guidance eliminates the requirement to estimate forfeitures and reduce stock compensation expense during the vesting period. Instead, companies can elect to account for actual forfeitures as they occur and record any previously unrecognized compensation expense for estimated forfeitures up to the period of adoption as a retrospective adjustment to beginning retained earnings. The Company has made the election to account for actual forfeitures as they occur starting in fiscal year 2017. After assessment, it was determined that the cumulative effect adjustment required under the new guidance was immaterial and therefore the Company did not record a retrospective adjustment. The Company finally determined that the adoption of this guidance did not have a significant impact on the consolidated financial position, results of operations and cash flows of the Company.
