Share-based Payment Arrangement [Text Block] | NOTE 9 – STOCK-BASED COMPENSATION PLANS AND WARRANTS The Company has issued options and has granted stock awards pursuant to its 2009 Equity Incentive Plan and 2019 Equity Incentive Plan, as described below. 2009 Equity Incentive Plan The 2009 Equity Incentive Plan was approved by stockholders at the 2009 Annual Meeting. The plan provides for the grant and issuance of up to 850,000 shares and options to the Company’s employees and consultants. The plan became effective when the Company filed a registration statement on Form S-8 on December 18, 2009. All options issued under the 2009 Equity Incentive Plan had a ten-year term with vesting periods ranging from issuance date to 24 months. 2019 Equity Incentive Plan The 2019 Equity Incentive Plan was approved by stockholders at the July 10, 2019 Annual Meeting. The plan provides for the grant and issuance of up to 1,200,000 shares and options to the Company’s employees, directors and consultants. Effective July 1, 2021, under the 2019 Equity Incentive Plan, each outside director receives $75,000 of cash compensation and receives a deferred stock award consisting of shares of the Company’s common stock with a value equal to $25,000 on June 30 of each year. The award accrues on a quarterly basis, with $18,750 of cash compensation and $6,250 of stock earned for each fiscal quarter in which a director serves. The deferred stock award vests automatically on the January 31 that first follows the award date. Stock Options to Directors, Officers and Consultants The Company had no options outstanding under either of the above plans as of December 31, 2021. For officers and employees of the Company, the fair value of each option granted under the plans was estimated on the date of grant using an option-pricing model. The risk-free interest rate is assumed to be equal to the yield of a U.S. Treasury bond of comparable maturity, as published in the Federal Reserve Statistical Release for the relevant date. The expected life estimate is based on an analysis of the employees receiving option grants and the expected behavior of each employee. The expected volatility is derived from an analysis of the historical volatility of the trading price per share of the Company’s common stock on the NASDAQ Global Market. The Company does not anticipate that it will pay dividends to common stockholders in the future. The Company recognized no stock-option-related compensation costs for the years ended December 31, 2021 and 2020 relating to these options. No stock options were exercised during 2021. No options were granted in 2021 and 2020. A summary of option activity under the plans as of December 31, 2021, and changes during the year ended December 31, 2020 are presented below:
