BENEFIT PLAN

 

The Company sponsors a benefit plan for the benefit of all eligible employees. The plan qualifies under Section 401(k) of the Internal Revenue Code thereby allowing eligible employees to make tax-deductible contributions to the plan. The plan provides for employer matching contributions of 50% of each participant’s voluntary contribution up to 3% of the participant’s compensation and vests at the rate of 20% each year until fully vested after five years. Total employer matching contributions to the plan were approximately $190,000, $198,000 and $176,000 in 2020, 2019 and 2018, respectively.
