Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based CompensationStock Options. At February 28, 2023 and November 30, 2022, we had 1,602,413 and 1,674,393 stock options outstanding with a weighted average exercise price of $15.55 and $15.56, respectively. We have not granted any stock option awards since 2016. In the 2023 first quarter, 71,980 stock options with a weighted average exercise price of $15.75 were exercised. As of February 28, 2023, stock options outstanding and stock options exercisable each had a weighted average remaining contractual life of 2.6 years. As all outstanding stock options have been fully vested since 2019, there was no stock-based compensation expense associated with stock options for the three-month periods ended February 28, 2023 and 2022. Stock options outstanding and stock options exercisable each had an aggregate intrinsic value of $31.6 million at February 28, 2023. (The intrinsic value of a stock option is the amount by which the market value of a share of the underlying common stock exceeds the exercise price of the stock option.)Other Stock-Based Awards. From time to time, we grant restricted stock and PSUs to various employees as a compensation benefit. We recognized total compensation expense of $5.9 million and $6.9 million for the three months ended February 28, 2023 and 2022, respectively, related to restricted stock and PSUs.
