Service-based vesting condition options

The fair value of each option award is estimated on the date of the grant using the Black-Scholes valuation model that uses the assumptions noted in the following table. Expected volatility is based on the historical volatility of the Company’s stock over the most recent period commensurate with the expected life of the Company’s stock options. The Company uses historical data to estimate option exercise and employee termination within the valuation model. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The expected term of options granted to employees is based upon historical exercise data. Expected dividends are based on the historical trend of the Company not issuing dividends.

There were 35,900 and 105,169 options granted during the twelve months ended November 30, 2021 and November 30, 2020, respectively.

The weighted average grant date fair value of options granted during the years ended November 30, 2021 and November 30, 2020 was $6.07 and $4.66, respectively.

The aggregate intrinsic value represents the total value of the difference between the Company’s closing stock price on the last trading day of the period and the exercise price of the options, multiplied by the number of in-the-money stock options that would have been received by the option holders had all option holders exercised their options on either November 30, 2021 or November 30, 2020, as applicable. The intrinsic value of the Company’s stock options changes based on the closing price of the Company’s stock.
