Defined Contribution Benefit Plan

13. Defined Contribution Benefit Plan

The Company maintains a defined contribution plan under Section 401(k) (the “401(k) Plan”) of the Internal Revenue Code, as amended (the “Code”). The 401(k) Plan covers all employees who meet defined minimum age and service requirements and allows participants to defer a portion of their annual compensation on a pretax basis, as well as Roth post tax deferrals. During 2021, the Company began to match 100% of compensation amounts deferred up to the first 1% of an employee's compensation plus 50% of compensation amounts deferred between 1% and 6% of an employee's compensation. All matching contributions are immediately vested. Expense recognized by the Company for matching contributions made in accordance with the 401(k) Plan was $0.6 million for the year ended December 31, 2021.
