Note 11—Employee Benefit Plans

We sponsor and maintain a 401(k) retirement savings plan (the “401(k) Plan”) for our employees who meet certain requirements. The 401(k) Plan permits participants to make pre-tax contributions by salary reduction pursuant to Section 401(k) of the Internal Revenue Code, as well as a Roth Plan that allows for after tax contributions. The 401(k) Plan requires for us to make a guaranteed match of a defined portion of the employee’s contributions. We contributed $0.9 million to the 401(k) Plan during 2022 and 2021, respectively.

We provide post-retirement life insurance benefits for certain retired employees. The plan is noncontributory and is unfunded, and therefore, benefits and expenses are paid from our general assets as they are incurred. All of the employees in the plan are fully vested, and the plan was closed to new employees in 1990. The discount rate used in determining the liability was 6.0% for 2022 and 2021. The following table presents the benefit obligation, which is included in accrued expenses in the accompanying balance sheets (in thousands).
