NOTE 6 – STOCK OPTIONS AND WARRANTS

Stock Options

As of October 31, 2021, the Company had 42,667 outstanding stock options to its directors and officers (collectively, “Employee Options”) and consultants (“Non-Employee Options”).

During the six months ended October 31, 2021, and 2020, the Company granted 1,334 and 1,333 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 six months ended October 31, 2021, and 2020, 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.
