DEFINED CONTRIBUTION PLANS

 

We maintain a 401(k) defined contribution plan covering all U.S. employees. Our matching contributions, net of forfeitures, under the plan, which are optional and based on the level of individual participant’s contributions, amounted to $58,000 and $46,000 in 2021 and 2020, respectively.
