Stock Option Plans Pursuant to its 2014 Stock Incentive Plan, we reserved 866,667 shares of common stock for issuance to employees, directors and consultants. As of September 30, 2021, there were options to purchase 855,171 shares outstanding, options to purchase 4,829 shares were exercised, options to purchase 6,667 shares expired, and no shares were available for future grants. On February 7, 2018, our stockholders approved the 2018 Omnibus Stock Incentive Plan and we reserved 2,000,000 shares of common stock for issuance to employees, directors and consultants. As of September 30, 2021, there were options to purchase 1,820,000 shares outstanding, options to purchase 70,000 shares were exercised and the remaining 110,000 shares were transferred to the 2020 Omnibus Stock Incentive Plan (“2020 Plan”). On February 10, 2020, our stockholders approved the 2020 Plan and we reserved 3,110,000 common shares. As of September 30, 2021, there were options to purchase 1,870,000 shares outstanding and the remaining 1,240,000 shares were transferred to the 2021 Omnibus Stock Incentive Plan (“2021 Stock Plan”). On May 24, 2021, our stockholders approved the 2021 Stock Plan and we reserved 8,740,000 shares. The 2021 Stock Plan provides incentives to employees, directors, and consultants through options, SARs, dividend equivalent rights, restricted stock, restricted stock units, or other rights. As of September 30, 2021, options to purchase 1,210,000 shares were outstanding and there were 7,530,000 shares available for future grants. The fair value of each stock option award is estimated on the date of grant using the Black-Scholes option pricing model. Volatility is estimated using the trading activity of our common stock. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant commensurate with the expected term assumption. The expected term of stock options granted to employees and directors, all of which qualify as “plain vanilla,” is based on the average of the contractual term (generally 10 years) and the vesting period. For non-employee options, the expected term is the contractual term. The following assumptions were used in determining the fair value of stock option grants for the years ended September 30, 2021 and 2020:
|  | 2021 |  | 2020 |
Risk-free interest rate |  | 0.32 – 0.89% |  | 0.26 – 1.66% |
Expected dividend yield |  | 0.00% |  | 0.00% |
Expected term |  | 6.50 – 10 years |  | 6.50 – 10 years |
Expected volatility |  | 111 – 112% |  | 107 – 117% |
