Retirement Benefits [Text Block] | Note 10 - 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 years ended December 31, 2020 and 2019, the Company matched 50% on the first 6% contributed by an employee, or a maximum of 3% of the employee’s income. For 2020 and 2019, we contributed $338 and $319, respectively, to the 401(k) plan.
