Stock Options And Warrants [Abstract] |
STOCK OPTIONS AND WARRANTS | Note 16. STOCK OPTIONS AND WARRANTS Stock-Based Compensation Stock Options In July 2017, the Board of Directors adopted the Company's 2017 Equity Incentive Plan ("2017 Plan") which authorized the grant of rights with respect to up to 1,200,000 shares. The 2017 Plan was approved by affirmative vote of the Company's stockholders on October 3, 2017. During the year ended December 31, 2020, the Company granted options to purchase 560,000 shares of common stock to certain of its employees and directors. The weighted average fair value of the granted options was estimated using the Black-Scholes option pricing model with the following assumptions: risk free interest rate of 0.22% to 1.61%; expected volatility factors of 71.5% to 75.4%; expected dividend yield of 0%; and expected life of 2.5 to 4 years. During the year ended December 31, 2019, the Company granted options to purchase 613,000 shares of common stock to certain of its employees and directors. The weighted average fair value of the granted options was estimated using the Black-Scholes option pricing model with the following assumptions: risk free interest rate of 1.87% to 2.60%; expected volatility factors of 65.8% to 72.4%; expected dividend yield of 0%; and expected life of 4.9 to 6.8 years. The Company recorded stock based compensation expense of $308,000 and $378,000 in its consolidated statement of operations for the years ended December 31, 2020 and 2019, respectively, and such amounts were included as a component of general and administrative expense. The fair values of stock options granted were estimated using the Black-Sholes option-pricing model with the following assumptions for the years ended December 31:
|  | 2020 |  |  | 2019 |
Risk-free interest rates |  |  | 0.22% - 1.61 | % |  |  | 1.87% - 2.60 | %
Expected life (in years) |  |  | 2.50 - 4.00 |  |  |  | 4.90 - 6.80 |
Expected volatility |  |  | 71.5% - 75.4 | % |  |  | 65.8% - 72.4 | %
Dividend yield |  |  | 0.00 | % |  |  | 0.00 | %
Weighted-average grant date fair value per share |  | $ | 0.64 |  |  | $ | 0.50 |
The expected life is the number of years that the Company estimates, based upon history, that the options will be outstanding prior to exercise or forfeiture. Expected life is determined using the "simplified method" permitted by Staff Accounting Bulletin No. 107. In addition to the inputs referenced above regarding the option pricing model, the Company adjusts the stock-based compensation expense for estimated forfeiture rates that are revised prospectively according to forfeiture experience. The stock volatility factor is based on the Company's experience. A summary of the status of the Company's stock options as of December 31, 2020 and 2019, and changes during the two years then ended are presented below.
