Equity [Abstract] |
EQUITY | NOTE 9—EQUITY (a) General At December 31, 2021 the Company had issued and outstanding 39,687,589 shares of its common stock, par value $0.01 per share. Holders of outstanding common stock are entitled to receive dividends when, as and if declared by the Board and to share ratably in the assets of the Company legally available for distribution in the event of a liquidation, dissolution or winding up of the Company. The Company is not authorized to issue preferred stock. Accordingly, no preferred stock is issued or outstanding. (b) Summary Employee Option Information The Company’s stock option plans provide for the grant to officers, directors and employees of options to purchase shares of common stock. The purchase price may be paid in cash or, if the option is “in-the-money” at the end of the option term, it is automatically exercised “net”. In a net exercise of an option, the Company does not require a payment of the exercise price of the option from the optionee but reduces the number of shares of common stock issued upon the exercise of the option by the smallest number of whole shares that has an aggregate fair market value equal to or in excess of the aggregate exercise price for the option shares covered by the option exercised. Each option is exercisable for one share of the Company’s common stock. Most options expire within five to ten years from the date of the grant, and generally vest over a three-year period from the date of the grant. At December 31, 2021, 1,580,620 options were available for grant under the Amended and Restated 2006 Stock Incentive Plan and no options were available for grant under the 2006 Stock Option Plan for Non-Employee Directors. In 2021 and 2020, 232,770 and 230,000 options, respectively, were granted to directors, executive officers and employees. In 2021 and 2020, there were no grants to non-employees (other than the non-employee directors and executive officers). The fair value of the options issued was approximately $89,000 and $59,000 in 2021 and 2020, respectively. No options were exercised in the year ended December 31, 2021. 96,250 options were exercised in the year ended December 31, 2020. The intrinsic value of options outstanding and of options exercisable at December 31, 2021 was approximately $291,000 and $217,000, respectively. The intrinsic value of options outstanding and of options exercisable at December 31, 2020 was approximately $29,000 and $46,000, respectively. The Company utilized the Black-Scholes option-pricing model to estimate fair value, utilizing the following assumptions for the respective years (all in weighted averages): SCHEDULE OF STOCK OPTIONS FAIR VALUE ASSUMPTIONS ESTIMATED USING BLACK-SCHOLES PRICING MODEL
|  | 2021 |  |  | 2020 |
Risk-free interest rate |  |  | 0.5 | % |  |  | 0.6 | %
Expected term of options, in years |  |  | 4.1 |  |  |  | 4.4 |
Expected annual volatility |  |  | 99.7 | % |  |  | 115.2 | %
Expected dividend yield |  |  | — | % |  |  | — | %
Determined weighted average grant date fair value per option |  | $ | 0.38 |  |  | $ | 0.25 |
The expected term of the options is the length of time until the expected date of exercising the options. With respect to determining expected exercise behavior, the Company has grouped its option grants into certain groups in order to track exercise behavior and establish historical rates. The Company estimated volatility by considering historical stock volatility over the expected term of the option. The risk-free interest rates are based on the U.S. Treasury yields for a period consistent with the expected term. The Company expects no dividends to be paid. The Company believes that the valuation technique and the approach utilized to develop the underlying assumptions are appropriate in determining the estimated fair value of the Company’s stock options granted in the years ended December 31, 2021 and 2020. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by persons who receive equity awards.
