Notes to Financial Statements
Compensation Related Costs, General [Text Block]	(8) Termination of Deferred Compensation Plan On May 5, 2020, our Compensation Committee and Board of Directors approved the termination of our Deferred Compensation Plan. The plan was an unfunded, nonqualified deferred compensation plan designed to allow board elected officers and other select members of our management designated by our Compensation Committee to save for retirement on a tax-deferred basis. The termination was effective May 5, 2021. All shares of Company common stock within the plan were distributed by March 31, 2022.

The entire disclosure for compensation costs, including compensated absences accruals, compensated absences liability, deferred compensation arrangements and income statement compensation items. Deferred compensation arrangements may include a description of an arrangement with an individual employee, which is generally an employment contract between the entity and a selected officer or key employee containing a promise by the employer to pay certain amounts at designated future dates, usually including a period after retirement, upon compliance with stipulated requirements. This type of arrangement is distinguished from broader based employee benefit plans as it is usually tailored to the employee. Disclosure also typically includes the amount of related compensation expense recognized during the reporting period, the number of shares (units) issued during the period under such arrangements, and the carrying amount as of the balance sheet date of the related liability.
