Share-Based Payment Arrangement [Abstract] |
STOCK BASED COMPENSATION | NOTE 10 – STOCK BASED COMPENSATION During 2007, the Board of Directors of the Company adopted the 2007 Employee Stock Plan (“2007 Plan”) that was approved by the shareholders. Under the 2007 Plan, the Company is authorized to grant options to purchase up to 10,000,000 shares of common stock to directors, officers, employees and consultants who provide services to the Company. The 2007 Plan is intended to permit stock options granted to employees under the 2007 Plan to qualify as incentive stock options under Section 422 of the Internal Revenue Code of 1986, as amended (“Incentive Stock Options”). All options granted under the 2007 Plan, which are not intended to qualify as Incentive Stock Options are deemed to be non-qualified options (“Non-Statutory Stock Options”). Effective June 24, 2016, the 2007 Plan was terminated. As of March 31, 2023, options to purchase 2,895,000 shares of common stock have been issued and are outstanding. During 2016, the Board of Directors of the Company adopted the 2016 Plan that was approved by the shareholders at the 2016 annual meeting of shareholders on May 20, 2016. Under the 2016 Plan, the Company is authorized to grant awards of incentive and non-qualified stock options and restricted stock to purchase up to 3,000,000 shares of common stock to employees, directors and consultants. Effective May 16, 2019, the number of shares of the Company’s common stock available for issuance under the 2016 Plan was increased from 3,000,000 to 8,000,000 shares. As of March 31, 2023, options to purchase 5,712,923 shares of common stock have been issued and are outstanding and 122,936 restricted shares of common stock are issued. As of March 31, 2023, 885,314 shares of common stock remain available for grants under the 2016 Plan. Both plans are administered by the Company’s Board of Directors or its compensation committee which determines the persons to whom awards will be granted, the number of awards to be granted, and the specific terms of each grant. Subject to the provisions regarding Ten Percent Shareholders, (as defined in the 2016 Plan), the exercise price per share of each option cannot be less than 100% of the fair market value of a share of common stock on the date of grant. Options granted under the 2016 Plan are generally exercisable for a period of 10 years from the date of grant and may vest on the grant date, another specified date or over a period of time. The Company uses the Black-Scholes option pricing model to calculate the grant-date fair value of an award, with the following assumptions for 2023: no dividend yield in all years, expected volatility, based on the Company’s historical volatility, 73.7% to 76.9%, risk-free interest rate between 3.49% to 3.94% and expected option life of 10 years. Prior to May 2018, the expected life is based on the estimated average of the life of options using the “simplified” method, as prescribed in FASB ASC 718, due to insufficient historical exercise activity during recent years. Starting in May 2018, the expected life is based on the legal contractual life of options. As of March 31, 2023, there was $5,427,714 of unrecognized compensation expense related to non-vested market-based share awards that is expected to be recognized through December 1, 2025. Share-based compensation was recognized as follows:

During the three month period ending March 31, 2023, 10,000 options were exercised for proceeds of $7,000 and 25,000 warrants were exercised for proceeds of $18,750.
