Note 9 - 401(k) Retirement Benefit Plan

We maintain a defined contribution 401(k) plan covering substantially all employees. Employees can contribute a portion of their salary or wages as prescribed under Section 401(k) of the Internal Revenue Code and, subject to certain limitations, we may, at the discretion of our Board of Directors, authorize an employer contribution based on a portion of the employees' contributions. For the year ended December 31, 2021, the Company matched 100% on the first 3% and 50% on the next 2% contributed by the employee, or a maximum of 4% of the employee’s income. For the year ended December 31, 2020, the Company matched 50% on the first 6% contributed by the employee, or a maximum of 3% of the employee’s income. For 2021 and 2020, we contributed $586 and $466, respectively, to the 401(k) plan.
