Share-based Payment Arrangement [Abstract]

Share Based Awards

Note 12 - Share Based Awards

Effective August 2019, shareholders approved the 2019 Equity Incentive Plan (the “Plan”) which allows us to incentivize key employees, consultants, and directors with long term compensation awards such as stock options, restricted stock, and restricted stock units (collectively, the “Awards”). The number of shares issuable in connection with Awards under the Plan may not exceed 8,750,000.

Options exercisable as of April 30, 2021 totaled 1,305,810. The remaining weighted average contractual term of the options outstanding at April 30, 2021 was 8.68 years. The aggregate intrinsic value of outstanding options, representing the excess of the stock price at April 30, 2021 of $4.04 over the exercise price of each option, was $4,943,870. As of April 30, 2021 and 2020, there was $914,915 and $1,009,731 of unrecognized stock-based compensation expense related to unvested stock options, net of estimated forfeitures, which is expected to be recognized over the weighted average period of 1.08 years.

The table below sets forth the assumptions used on the date of grant for estimating the fair value of options granted during the years ended April 30, 2020 and April 30, 2021:  

	2021			2020

Stock price on date of grant		2.01 - 3.95			0.82 - 2.10
Volatility		88.60% - 91.44	%		75	%
Risk-free interest rate		0.38% - 1.66	%		1.59 - 1.74	%
Expected term (years)		5.87 - 10.00			5.00 - 10.00
