401(k) Savings Plan 401(k) Savings PlanWe have a defined contribution savings plan under Section 401(k) of the Internal Revenue Code. This plan covers substantially all employees who meet minimum age and service requirements and allows participants to defer a portion of their annual compensation on a pre-tax basis. Under the 401(k) plan, matching contributions are based upon the amount of the employees’ contributions subject to certain limitations. We contributed $2.3 million, $1.8 million and $1.7 million to the 401(k) plan in 2021, 2020 and 2019, respectively.
