In January 2009, the Company adopted a 401(k) retirement savings plan, or 401(k) Plan, covering substantially all employees. Employees can contribute between 1% and 50% of their total earnings. The 401(k) Plan also provides for employer contributions to be made at the Company's discretion.
The Company makes matching contributions equal to 50% of employee contributions, which could be applied to up to 6% of each participant's compensation. Employees are eligible to participate upon date of hire and are immediately vested in all matching contributions. The Company's policy prohibits participants from direct investment in shares of its common stock within the plan. The Company's contributions charged to expense were $7.8 million, $7.2 million and $5.4 million for the years ended December 31, 2023, 2022 and 2021, respectively.
