Schedule of assumptions used in valuation of share-based compensation awards

The table set forth below provides the estimated fair value of options granted by the Company during fiscal years 2024, 2023 and 2022 and the significant weighted average assumptions used in determining such fair value under the Black-Scholes option-pricing model. The average expected life represents an estimate of the period of time stock options are expected to remain outstanding based on the historical exercise behavior of the option grantees. The risk-free interest rate was based on the U.S. Treasury yield curve corresponding to the expected life in effect at the time of the grant. The volatility was estimated based on historical volatility corresponding to the expected life.
