Stock-Based Compensation [Abstract] |
STOCK-BASED COMPENSATION | NOTE 5 – STOCK-BASED COMPENSATION Amended 2017 Equity Incentive Plan In October 2017, the Company’s Board approved the 2017 Equity Incentive Plan (the Plan) with 1,000,000 shares of common stock reserved for issuance. In January 2020 and August 2021, the Board approved increases in the number of shares reserved for issuance under the Plan by 333,334 and 1,333,334 shares, respectively. In January 2023 and February 2024, the Company’s stockholders approved increases in the number of shares reserved for issuance under the Plan by an additional 2,000,000 and 3,000,000 shares, respectively. Under the Plan, eligible employees, directors and consultants may be granted a broad range of awards, including stock options, stock appreciation rights, restricted stock, performance-based awards and restricted stock units (RSUs). The Plan is administered by the Board or, in the alternative, a committee designated by the Board. Stock-Based Compensation Expense Stock options granted by the Company generally vest over 36 months and have a 10-year term. As of March 31, 2024, the unamortized compensation cost related to stock options was approximately $2,035,000 and is expected to be recognized as expense over a weighted-average period of approximately 1.3 years. In October 2023, under its Two-Part FDA Submission and Clearance Milestone Bonus Program (the Bonus Program), the Company granted stock options for 909,533 shares, which are subject to vesting based upon the achievement of certain performance milestones by the Company and continued service by the optionees. In January 2024, options to purchase 625,326 shares (net of forfeitures), which were granted under part one of the Bonus Program, vested upon the Company’s submission to the FDA. As of March 31, 2024, the Company had not commenced expense recognition of 242,307 (net of forfeitures) of the options, which were granted under part two of the Bonus Program, based on its assessment of the probability of achievement of the applicable performance requirements. During the year ended March 31, 2024, the Company granted options to purchase 127,500 shares that vested immediately when granted. The weighted-average grant date fair values of stock options granted during the years ended March 31, 2024 and 2023 was $0.99 and $2.85, respectively. The following assumptions were used in the fair-value method calculations:
|  |  | Year Ended March 31, |
|  |  | 2024 |  |  |  | 2023 |
Risk-free interest rates |  |  | 3.51% - 4.72% |  |  |  | 2.82% - 4.06% |
Volatility |  |  | 83% - 152% |  |  |  | 83% - 223% |
Expected life (years) |  |  | 5.0 - 6.2 |  |  |  | 5.0 – 5.7 |
Dividend yield |  |  | — |  |  |  | — |
The fair values of options at the grant date were estimated utilizing the Black-Scholes valuation model, which includes simplified methods to establish the fair term of options. The expected volatility is based on the historical volatility of the Company’s stock price. The risk-free interest rate was derived from the Daily Treasury Yield Curve Rates, as published by the U.S. Department of the Treasury as of the grant date for terms equal to the expected terms of the options. A dividend yield of zero was applied because the Company has never paid dividends and has no intention to pay dividends in the foreseeable future. The Company accounts for forfeitures as they occur. The following table summarizes the activity in the shares available for grant under the Plan during the year ended March 31, 2024:
