Share-based Payment Arrangement [Abstract] |
Share-Based Compensation | Note 10 – Share-Based Compensation The Company’s current share-based compensation plans, approved by the stockholders of the Company, provides for awards of stock options, restricted shares, restricted stock units (“RSUs”), stock appreciation rights, performance shares, and performance stock units (“PSUs”) to employees and non-employee directors of the Company. The Company measures and recognizes compensation expense for all share-based payment awards made to employees and directors based on estimated fair values. Share-based compensation expense was $1.3 million and $1.7 million for the three months ended November 30, 2021 and 2020, respectively. The following table illustrates the type and fair value of share-based compensation awards granted during the three months ended November 30, 2021 and 2020, respectively:
|  | Three months ended |
|  | November 30, 2021 |  |  | November 30, 2020 |
|  | Number of units granted |  |  | Weighted average grant-date fair value per award |  |  | Number of units granted |  |  | Weighted average grant-date fair value per award |
Stock options |  |  | 21,137 |  |  | $ | 41.80 |  |  |  | 35,168 |  |  | $ | 30.68 |
RSUs |  |  | 20,099 |  |  | $ | 141.99 |  |  |  | 26,314 |  |  | $ | 106.72 |
PSUs |  |  | 12,122 |  |  | $ | 147.74 |  |  |  | 19,533 |  |  | $ | 125.23 |
The RSUs granted during the three months ended November 30, 2021 and 2020 included 2,248 and 2,162 awards, respectively, that will be settled in cash. The weighted average stock price on the date of grant was $145.93 and $110.21 per award for the three months ended November 30, 2021 and 2020, respectively. Share issuances are presented net of share repurchases to cover payroll taxes of $1.2 million and $1.3 million for the three months ended November 30, 2021 and 2020, respectively. The following table provides the assumptions used in determining the fair value of the stock options awarded during the three months ended November 30, 2021 and 2020, respectively:
|  | Three months ended November 30, |
|  | 2021 |  |  | 2020 |
Weighted-average dividend yield |  |  | 0.9 | % |  |  | 1.2 | %
Weighted-average volatility |  |  | 33.8 | % |  |  | 32.8 | %
Risk-free interest rate |  |  | 1.2 | % |  |  | 0.5 | %
Weighted-average expected life (years) |  |  | 5 |  |  |  | 6 |
The PSUs granted during fiscal 2022 include performance goals based on a return on invested capital ("ROIC") and total shareholder return ("TSR") relative to the Company's peers during the performance period. The awards actually earned will range from zero to two hundred percent of the targeted number of PSUs and will be paid in shares of common stock. Shares earned will be distributed upon vesting on the first day of November following the end of the three-year performance period. For the ROIC portion of the award, the Company is accruing compensation expense based on the estimated number of shares expected to be issued utilizing the most current information available to the Company at the date of the consolidated financial statements. For the TSR portion of the award, compensation expense is recorded ratably over the three-year term of the award based on the estimated grant date fair value. The fair value of the TSR portion of the awards granted during the three months ended November 30, 2021 and 2020 was estimated at the grant date using a Monte Carlo simulation model which included the following assumptions:
|  | Three months ended November 30, |
|  | 2021 |  |  | 2020 |
Expected term (years) |  |  | 3 |  |  |  | 3 |
Risk-free interest rate |  |  | 0.7 | % |  |  | 0.2 | %
Volatility |  |  | 39.1 | % |  |  | 38.6 | %
Dividend yield |  |  | 0.9 | % |  |  | 1.2 | %
