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 with the match paid 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) $34.5 million and $30.3 million related to the plan in the six-month periods ended June 30, 2021 and 2020, respectively. Our b oard of d irectors authorized the use of common stock to fund our 2020 employer matching contribution s to the 401(k) plan, which we funded in February 2021. During second quarter 2021, our board of directors authorized a 5.0% employer match on eligible compensation to the 401(k) plan for the 2021 plan year and the possible use of common stock to fund our 2021 employer matching contributions, which is expected to be funded in February 2022.
