Summary of Fair Value of Stock Options at Grant Date

We use the Black-Scholes-Merton option pricing model for valuation of stock option awards. Calculating the fair value of stock option awards requires the input of subjective assumptions. Other reasonable assumptions could provide differing results. The fair value of stock options at the grant date was determined using the following assumptions:

	Year Ended February 29/28,
Black-Scholes Valuation Assumptions	2020	2019	2018
Expected life (years)	6	2 - 6	6
Expected volatility	43%	36% - 43%	46%
Risk-free interest rates	1.9%	2.5% - 2.9%	2.0%
Expected dividend yield	0%	0%	0%
