Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting Policies Organization Seagate Technology Holdings plc (“STX”) and its subsidiaries (collectively, unless the context otherwise indicates, the “Company”) is a leading provider of data storage technology and solutions. Its principal products are hard disk drives, commonly referred to as disk drives, hard drives or HDDs. In addition to HDDs, the Company produces a broad range of data storage products including solid state drives (“SSDs”), solid state hybrid drives (“SSHDs”), storage subsystems, as well as a scalable edge-to-cloud mass data platform that includes data transfer shuttles and a storage-as-a-service cloud. HDDs are devices that store digitally encoded data on rapidly rotating disks with magnetic surfaces. HDDs continue to be the primary medium of mass data storage due to their performance attributes, reliability, high capacities, superior quality and cost effectiveness. Complementing existing storage architectures, SSDs use integrated circuit assemblies as memory to store data, and most SSDs use NAND flash memory. In contrast to HDDs and SSDs, SSHDs combine the features of SSDs and HDDs in the same unit, containing a high-capacity HDD and a smaller SSD acting as a cache to improve performance of frequently accessed data. The Company’s HDD products are designed for mass capacity storage and legacy markets. Mass capacity storage involves well-established use cases—such as hyperscale data centers and public clouds as well as emerging use cases. Legacy markets include markets the Company continues to service but that it does not plan to invest in significantly. The Company’s HDD and SSD product portfolio includes Serial Advanced Technology Attachment, Serial Attached SCSI and Non-Volatile Memory Express based designs to support a wide variety of mass capacity and legacy applications. The Company’s system portfolio includes storage subsystems for enterprises, cloud service providers, scale-out storage servers and original equipment manufacturers (“OEMs”). Engineered for modularity, mobility, capacity and performance, these solutions include the Company’s enterprise HDDs and SSDs, enabling customers to integrate powerful, scalable storage within legacy environments or build new ecosystems from the ground up in a secure, cost-effective manner. The Company’s Lyve portfolio provides a simple, cost-efficient and secure way to manage massive volumes of data across the distributed enterprise. The Lyve platform includes a shuttle solution that enables enterprises to transfer massive amounts of data from endpoints to the core cloud, a storage-as-a-service cloud that provides frictionless mass capacity storage at the metro edge, a converged object storage solution enabling efficient capture and consolidation of massive data sets and Cortx, an open-source object storage software optimized for mass capacity and data intensive workloads. Basis of Presentation and Consolidation The unaudited Condensed Consolidated Financial Statements of the Company and the accompanying notes were prepared in accordance with United States (“U.S.”) Generally Accepted Accounting Principles (“GAAP”). The Company’s unaudited condensed consolidated financial statements include the accounts of the Company and all its wholly-owned and majority-owned subsidiaries, after elimination of intercompany transactions and balances. The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the Company’s condensed consolidated financial statements and accompanying notes. These estimates and assumptions include the impact of the COVID-19 pandemic. Actual results could differ materially from those estimates. The methods, estimates and judgments the Company uses in applying its most critical accounting policies have a significant impact on the results the Company reports in its condensed consolidated financial statements. The Company’s consolidated financial statements for the fiscal year ended July 2, 2021 are included in its Annual Report on Form 10-K, as filed with the U.S. Securities and Exchange Commission (“SEC”) on August 6, 2021. The Company believes that the disclosures included in these unaudited condensed consolidated financial statements, when read in conjunction with its consolidated financial statements as of July 2, 2021, and the notes thereto, are adequate to make the information presented not misleading. The results of operations and the cash flows for the three and six months ended December 31, 2021 are not necessarily indicative of the results to be expected for any subsequent interim period or for the Company’s fiscal year ending July 1, 2022. Fiscal Year The Company operates and reports financial results on a fiscal year of 52 or 53 weeks ending on the Friday closest to June 30. In fiscal years with 53 weeks, the first quarter consists of 14 weeks and the remaining quarters consist of 13 weeks each. The three and six months ended December 31, 2021 consisted of 13 and 26 weeks, respectively, and the three and six months ended January 1, 2021 consisted of 13 and 26 weeks, respectively. Fiscal year 2022, which ends on July 1, 2022, is comprised of 52 weeks and fiscal year 2021, which ended on July 2, 2021, was comprised of 52 weeks. The fiscal quarters ended December 31, 2021, October 1, 2021 and January 1, 2021, are also referred to herein as the “December 2021 quarter”, the “September 2021 quarter” and the “December 2020 quarter”, respectively. Summary of Significant Accounting Policies There have been no material changes to the Company’s significant accounting policies disclosed in Note 1. Basis of Presentation and Summary of Significant Accounting Policies of “Financial Statements and Supplementary Data” contained in Part II, Item 8. of the Company’s Annual Report on Form 10-K for the fiscal year ended July 2, 2021, as filed with the SEC on August 6, 2021. Recently Adopted Accounting Pronouncements In December 2019, the Financial Accounting Standards Board (“FASB”) issued ASU 2019-12 (ASC Topic 740), Simplifying the Accounting for Income Taxes. This ASU simplifies accounting for income taxes by removing certain exceptions to the general principles and amending existing guidance to improve consistent application. This ASU became effective and the Company adopted the guidance in the September 2021 quarter. The adoption of this ASU did not have an impact on the Company’s condensed consolidated financial statements. In July 2021, the FASB issued ASU 2021-05 (ASC Topic 842), Lessors—Certain Leases with Variable Lease Payments. This ASU requires lessors to classify and account for a lease with variable lease payments that do not depend on a reference index or a rate as an operating lease if the lease would have been classified as a sales-type lease or a direct financing lease and the lessor would have otherwise recognized a day-one loss. The Company adopted the guidance in the September 2021 quarter on a prospective basis. The adoption of this ASU did not have an impact on the Company’s condensed consolidated financial statements.
