Stock Options | NOTE 5 - Stock Options The Company measures share-based compensation cost on the grant date, based on the fair value of the award, and recognizes the expense on a straight-line basis over the requisite service period for awards expected to vest. The Company estimated the grant date fair value of stock options using a Black-Scholes valuation model using the following weighted-average assumptions: Assumptions Years Ended August 31, 2021 2020 Expected dividend yield – – Expected stock price volatility 89.44 % 82.94 – 86.23 % Risk-free interest rate 0.19 % 1.40 – 1.69 % Expected term (in years)(simplified method) 4.00 1.87 – 5.75 Exercise price $ 3.42 $ 2.32 - $ 8.00 Weighted-average grant date fair-value $ 2.16 $ 1.15 - $ 1.84 A summary of the Company’s stock option activity for the years ended August 31, 2021 and 2020 and related information follows: Stock option activity Number of Shares Subject to Option Grants Weighted Average Exercise Price ($) Weighted Average Remaining Contractual Term Aggregate Intrinsic Value ($) Outstanding at August 31, 2019 2,777,334 4.31 Grants 5,158,000 4.06 Forfeitures and cancellations (130,600 ) 3.54 Outstanding at August 31, 2020 7,804,734 4.16 Grants 50,000 3.42 Exercises (56,667 ) 4.95 Forfeitures and cancellations (1,057,667 ) 5.30 Outstanding at August 31, 2021 (years) 6,740,400 3.97 4.29 13,275,179 Exercisable at August 31, 2021 (years) 5,980,900 4.02 4.45 11,655,544 The aggregate intrinsic value in the table above represents the total pretax intrinsic value for all “in-the-money” options (i.e. the difference between the Company’s closing stock price on the last trading day of the period covered by this report and the exercise price, multiplied by the number of shares) that would have been received by the option holders had all in-the-money option holders exercised their vested options on August 31, 2021.
