Stock-Based Compensation
Stock-Based Compensation	Note 6 - Stock-Based Compensation Under the terms of our 2016 Omnibus Incentive Plan, directors, officers and key employees could be granted restricted stock units and stock awards, as well as non-qualified or incentive stock options, at the discretion of the Compensation Committee of the Board of Directors. All stock-based payments to directors and employees, including grants of stock options and stock purchase rights, are recognized in the financial statements based on their respective grant date (measurement date) fair values. We calculate the compensation cost of full-value awards such as restricted stock units and stock awards based on the market value of the underlying stock at the date of the grant. The fair value of stock option awards is estimated at the date of grant using the Black-Scholes option pricing model; however, the value calculated using an option pricing model may not be indicative of the fair value observed in a willing buyer/willing seller market transaction, or actually realized by the employee upon exercise. Expected volatility used to estimate the fair value of options granted is based on the historical volatility of our common stock. The risk-free interest rate is based on the United States Treasury constant maturity rate for the expected life of the stock option. The expected life of a stock award is the period of time that the award is expected to be outstanding. We recognize compensation expense for all stock-based awards on a straight-line basis over the requisite service period for the entire award. The amount of compensation expense recognized through the end of each reporting period is equal to the portion of the grant-date value of the awards that have vested, or for partially vested awards, the value of the portion of the award that is ultimately expected to vest for which the requisite services have been provided. The benefits of tax deductions in excess of recognized compensation cost are reported as a financing cash flow. As of December 31, 2022, there were no stock-based compensation awards outstanding. The stock-based compensation expense recorded in the years ended December 31, 2022 and 2021 was for shares of common stock issued to members of the Board of Directors as partial compensation for their service as a director.
