Defined Contribution Plan
15. Defined Contribution Plan
We have a defined contribution 401(k) plan (the "401K Plan") covering substantially all employees. Employees were able to contribute between 1% and 75% of their salaries in 2022, 2021 and 2020. We match 50% of qualified employees’ contributions up to 6% of their salary. The 401K Plan also provides for additional employer contributions to be made at our discretion. We suspended our 401(k) match program between April 1, 2020 and December 31, 2020 in response to COVID-19. Total matching contributions to the 401K Plan for the years ended December 31, 2022, 2021 and 2020 were $9.3 million, $6.5 million and $1.9 million, respectively.
In December 2020, we made a discretionary matching contribution to eligible employees 401(k) plans totaling $1.2 million, given our financial performance during the fourth quarter. There were no discretionary contributions by us to the 401K Plan in 2022 and 2021.
