Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Organization and Basis of Presentation | Organization and Basis of Presentation Western Digital Corporation (“Western Digital” or the “Company”) is a leading developer, manufacturer, and provider of data storage devices and solutions based on both flash-based products (“Flash”) and hard disk drives (“HDD”) technologies. With dedicated Flash and HDD business units driving advancements in memory technologies, the Company creates and drives innovations needed to help customers capture, preserve, access, and transform an ever-increasing diversity of data. The accounting policies followed by the Company are set forth in Part II, Item 8, Note 1, Organization and Basis of Presentation, of the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10‑K for the year ended July 1, 2022. In the opinion of management, all adjustments necessary to fairly state the Condensed Consolidated Financial Statements have been made. All such adjustments are of a normal, recurring nature. Certain information and footnote disclosures normally included in the Consolidated Financial Statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). These Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and the notes thereto included in the Company’s Annual Report on Form 10‑K for the year ended July 1, 2022. The results of operations for interim periods are not necessarily indicative of results to be expected for the full year. Fiscal Year The Company’s fiscal year ends on the Friday nearest to June 30 and typically consists of 52 weeks. Approximately every five to six years, the Company reports a 53-week fiscal year to align the fiscal year with the foregoing policy. Fiscal years 2023, which ends on June 30, 2023, and 2022, which ended on July 1, 2022, are each comprised of 52 weeks, with all quarters presented consisting of 13 weeks. Segment Reporting The Company manufactures, markets, and sells data storage devices and solutions in the U.S. and in foreign countries through its sales personnel, dealers, distributors, retailers, and subsidiaries. The Company manages and reports under two reportable segments: Flash and HDD. The Company’s Chief Operating Decision Maker (“CODM”) evaluates performance of the Company and makes decisions regarding allocation of resources based on each operating segment’s net revenue and gross margin. Because of the integrated nature of the Company’s production and distribution activities, separate segment asset measures are not available or reviewed by the CODM to evaluate the performance of or to allocate resources to the segments. Use of Estimates Company management has made estimates and assumptions relating to the reporting of certain assets and liabilities in conformity with U.S. GAAP. These estimates and assumptions have been applied using methodologies that are consistent throughout the periods presented with consideration given to the potential impacts of current macroeconomic conditions. However, actual results could differ materially from these estimates.
