[1] (1) During the three and six months ended April 30, 2022, we recognized stock-based compensation expense relating to restricted stock units (RSUs), granted to senior executives in February 2022 with certain market, performance and service conditions (market-based RSUs). Under the award agreements, the vesting of the market-based RSUs is contingent on achieving total stockholder return (TSR) relative to a peer index as well as revenue growth metrics. The performance period during which the achievement goals will be measured is fiscal 2022 and fiscal 2023. The maximum potential awards that may be earned are 187.5% of the target number of the initial awards. The awards will vest in equal increments in December 2023 and December 2024 if the TSR target, revenue growth metrics, and service conditions are achieved. The grant date fair value for the market-based RSUs of $280.82 was determined using a Monte Carlo simulation model with the following assumptions: expected volatility of 33.01%, risk-free interest rate of 1.33% and an expected term of 1.69 years.
