We have a qualified contributory savings and thrift 401(k) plan covering the majority of our domestic employees. For eligible employees who have met the plan’s age and service requirements to receive matching contributions, we historically have matched 100% of pre-tax and Roth elective deferrals up to a maximum of 5.0% of eligible compensation, subject to federal limits on plan contributions and not in excess of the maximum amount deductible for federal income tax purposes. Beginning in 2021, the amount matched by the company will be discretionary and annually determined by management. Employees must be employed and eligible

for the plan on the last day of the plan year to receive a matching contribution, subject to certain exceptions enumerated in the plan document. Matching contributions are subject to a five-year graduated vesting schedule and can be funded in cash or company stock. We expensed (net of plan forfeitures) $63.6 million, $59.4 million and $53.9 million related to the plan in 2020, 2019 and 2018, respectively. Our board of directors has authorized use of common stock to fund our 2020 employer matching contributions to the 401(k) plan, which we plan to do in February 2021.
