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 domestic employees, subject to certain eligibility requirements. Eligible employees receive employer matching contributions immediately upon hire unless the individual is covered by a collective bargaining agreement, provides services as a consultant, intern, independent contractor, leased or temporary employee, or otherwise is not treated as a common-law employee. Through December 31, 2021, eligible employees were generally able to contribute up to 75% of their eligible compensation on a combined pre-tax and Roth basis, 10% on a combined pre-tax catch-up and Roth catch-up basis, and 10% on a non-Roth after-tax basis subject to Internal Revenue Service (“IRS”) limitations. Effective January 1, 2022, eligible employees are generally 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 by payroll withholding. The Company makes 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. Prior to January 1, 2022, the Company’s employer matching contributions vested over a two-year graded period through December 31, 2021 with all unvested contributions vesting on December 31, 2021 and, effective January 1, 2022, the Company’s employer matching contributions vest immediately. The Company may suspend matching contributions at any time at its discretion. 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. For 2022, 2021 and 2020, the Company made Plan contributions of $36 million, $34 million and $33 million, respectively.
