The fair value of stock options is determined using the Black-Scholes valuation model. Such fair value is recognized as an expense over the service period, net of forfeitures. Stock-based compensation expense was $47,000 and $147,000 for the three months ended January 31, 2021 and January 31, 2020, respectively.
