Pension and Other Postretirement Benefits Disclosure [Text Block] | Note 9 . Employee Benefit Plans We adopted our 401 (k) plan effective January 1, 2000. Participation is voluntary and employees are eligible the first day of the following month that an employee attains an age of 21 and one hour of service time. We match 100 percent of the employee’s contributions up to four percent of the employee’s salary and those contributions are vested immediately. Prior to January 1, 2017, we matched 50 percent of the employee’s contribution up to six percent of the employee’s salary and those contributions were vested immediately.
