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. Eligible employees are generally able to contribute up to 30% of their eligible compensation on a pre-tax basis or 10% of their eligible compensation on an after-tax basis subject to Internal Revenue Service (“IRS”) limitations. The Company makes a basic matching contribution equal to 50% of the each eligible participant’s contribution that does not exceed 6% of the eligible participant’s annual compensation in the year of contribution. The Company’s employer matching contributions vest over a two-year graded period. 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 2018, 2017 and 2016, the Company made Plan contributions of $35 million, $36 million and $20 million, respectively.
