Retirement Benefits [Abstract] |
Western Digital Corporation 401(k) Plan | Western Digital Corporation 401(k) Plan The Company maintains the Western Digital Corporation 401(k) Plan (the “Plan”). The Plan covers substantially all U.S. employees, subject to certain eligibility requirements. Eligible employees receive employer matching contributions immediately upon hire. Eligible employees do not include individuals that are covered by a collective bargaining agreement, provide services as a consultant, interns, independent contractors, leased or temporary employees, or who otherwise are not treated as common-law employees. Eligible employees are able to contribute up to 85% of their eligible compensation on a combined pre-tax and Roth basis regardless of age, and 10% of their eligible compensation on an after-tax basis, all subject to U.S. Internal Revenue Service (“IRS”) limitations. The Company may make a basic matching contribution equal to 50% of each eligible participant’s contribution that does not exceed 6% of the eligible participant’s annual compensation in the year of contribution. Furthermore, the Company’s employer matching contributions vest immediately. Contributions, including the Company’s matching contribution to the Plan, are recorded as soon as administratively possible after the Company makes payroll deductions from Plan participants. Effective February 18, 2023, the Company announced its decision to suspend its previous practice of matching contributions. The Company later resumed matching contributions effective January 1, 2024. For 2025, 2024 and 2023, the Company made Plan contributions of $22 million, $8 million and $13 million, respectively.
