Notes to Financial Statements
Treasury Stock [Text Block]	Note 11 – Common Stock Repurchases During the years ended December 31, 2021 and 2020, we repurchased 327,563 and 135,154 treasury shares, respectively, with an aggregate value of approximately $197,000 and $174,000 respectively, associated with the vesting of restricted stock held by employees or upon the exercise of stock options held by employees. Per terms of the restricted stock agreements, for certain employees we paid the employee’s related taxes associated with the employee’s vested stock and decreased the freely tradable shares issued to the employee by a corresponding value, resulting in a share issuance net of taxes to the employee. The value of the shares netted for employee taxes represents treasury stock repurchased. Per terms of the stock option agreements, for certain employees we paid the exercise price of the stock option and decreased the freely tradable shares issued to the employee by a corresponding value, resulting in a share issuance, net of exercise price to the employee.
