NOTE 6 – STOCK OPTIONS AND WARRANTS

2021 Equity Incentive Plan

Effective June 30, 2021, the Company implemented the 2021 Equity Incentive Plan (“2021 Equity Plan”) as approved by the Company’s stockholders. The 2021 Equity Plan is administered by the Compensation Committee of the Board and has 166,667 shares available under this plan. The 2021 Equity Plan can issue various types of awards, as follows: stock options, stock appreciation rights, restricted stock, restricted stock units, and cash or other stock-based awards. The 2021 Equity Plan is available to be issued to employees, directors, consultants, and other individuals who provide services to the Company. An incentive stock options (“ISOs”) can only be granted to employees and shall not exceed 10-years (5-years in the case of ISOs granted to any 10% shareholder).

Stock Options

As of April 30, 2022, the Company had 40,900 outstanding stock options to its directors and officers (collectively, “Employee Options”) and consultants (“Non-Employee Options”).

During the years ended April 30, 2022, and 2021, the Company granted 7,334 and 7,333 Employee Options, respectively.

The fair value of the Employee Options at the date of grant was estimated using the Black-Scholes-Merton option-pricing model, based on the following weighted average assumptions: 

The Company’s computation of expected volatility is based on the historical daily volatility of its publicly traded stock. For stock option grants issued during the years ended April 30, 2022, and 2021, the Company used a calculated volatility for each grant. The Company lacks adequate information about the exercise behavior now and has determined the expected term assumption under the simplified method provided for under ASC 718, which averages the contractual term of the Company’s stock options of five years with the average vesting term of two and one-half years for an average of three years. The dividend yield assumption of zero is based upon the fact the Company has never paid cash dividends and presently has no intention of paying cash dividends. The risk-free interest rate used for each grant is equal to the U.S. Treasury rates in effect at the time of the grant for instruments with a similar expected life.

During the years ended April 30, 2022, and 2021, the Company granted no Non-Employee Options.

A summary of the Company’s stock option activity and related information for the two years ended April 30, 2022 are shown below: 

A summary of the activity for unvested stock options during the years ended April 30, 2022, and 2021 is as follows: 

The Company recorded $44,800 and $176,568 of stock-based compensation related to the issuance of Employee Options to certain officers and directors in exchange for services during the years ended April 30, 2022, and 2021, respectively. At April 30, 2022, there remained $7,777 of unrecognized compensation expense related to unvested Employee Options granted to officers and directors, to be recognized as expense over a weighted-average period of the remaining eight months in the calendar year. The unvested options vest at 500 shares per month and are expected to be fully vested on December 31, 2022.

The following table summarizes the outstanding stock options by exercise price at April 30, 2022: 

The aggregate intrinsic value of outstanding options as of April 30, 2022, was $0. This represents options whose exercise price was less than the closing fair market value of the Company’s common stock on April 30, 2022, of approximately $2.33 per share.

Warrants

The warrants issued by the Company are equity classified. The fair value of the warrants was recorded as additional paid-in-capital, and no further adjustments are made.

The warrants are immediately exercisable and do not embody an obligation for the Company to repurchase the shares. The warrants also permit the holders to receive a fixed number of shares upon exercise and do not provide any guarantee of value or return.
