Retirement savings plan

7. Retirement savings plan

We maintain a 401(k) plan under which all full-time employees are eligible to participate at the beginning of the month immediately following their date of hire.  We match employees’ contributions at a rate of 50% of employees’ contributions up to the first 6% of the employees’ compensation contributed to the 401(k) plan.  Our matching contributions, net of applied forfeitures, were $230 thousand and $355 thousand in 2023 and 2022, respectively.
