The Company may grant stock options that generally vest over a period of one year. Stock options become exercisable over the vesting period in installments determined by the Company, which can vary depending upon each individual grant. Stock options granted to non-employee directors generally vest over a period of one year.

There were no stock options granted in the fiscal year ended January 31, 2022 and 2021, as beginning in fiscal 2021, the Company began to grant restricted stock units to non-employee directors instead of stock options. A Black-Scholes model was used to estimate the fair value of stock options granted in the fiscal year ended January 31, 2020. The model uses assumptions including the risk-free rate of interest, expected volatility of the Company’s stock price and expected life of the awards. The Company uses historical data on exercise timing to determine the expected life assumption. The risk-free rate of interest for periods within the contractual life of the award is based on U.S. Government Securities Treasury Constant Maturities over the expected term of the equity instrument. The expected volatility is based on a weighted-average of the implied volatility and the Company’s most recent historical volatility. The following weighted-average assumptions were used in the models to estimate the fair value of stock options at the date of grant:

	Fiscal Year Ended January 31,
	2022		2021		2020
Expected life, in years		—		—		5.3
Risk-free interest rate		—		—		1.9	%
Volatility		—		—		37.6	%
Dividend rate		—		—		—
