Earnings Per Share [Abstract] |
Earnings Per Share | Earnings Per ShareBasic earnings per share is computed by dividing net earnings available to common stockholders by the weighted average number of common shares outstanding. Diluted earnings per share is computed similarly but reflects the potential dilution that would occur if dilutive options were exercised, all unvested share-based payment awards were vested, and other distributions related to deferred stock agreements were incurred. Common stock equivalents are calculated using the treasury stock method. The dilutive effects of share-based payment awards subject to market and/or performance conditions that were not met during the period are excluded from the computation of diluted earnings per share. The following table calculates basic earnings per common share and diluted earnings per common share for the periods presented (in millions, except per share data):

Net income | $ | 75.3 |  |  | $ | 62.9 |  |  | $ | 162.9 |  |  | $ | 122.5 |
Basic weighted average shares outstanding | 35.0 |  |  | 36.0 |  |  | 35.0 |  |  | 36.9 |
Common stock equivalents | 0.4 |  |  | 0.2 |  |  | 0.4 |  |  | 0.2 |
Diluted weighted average shares outstanding | 35.4 |  |  | 36.2 |  |  | 35.4 |  |  | 37.1 |
Basic earnings per share | $ | 2.16 |  |  | $ | 1.75 |  |  | $ | 4.65 |  |  | $ | 3.32 |

The following table presents stock options, performance stock awards, and restricted stock awards that were excluded from the diluted earnings per share calculation for the periods presented as the effect of inclusion would have been antidilutive (in millions):
| Three Months Ended |  | Six Months Ended
| February 28, 2022 |  | February 28, 2021 |  | February 28, 2022 |  | February 28, 2021
Stock options | 0.1 |  |  | 1.0 |  |  | 0.1 |  |  | 1.1 |
Restricted stock awards | 0.1 |  |  | 0.1 |  |  | 0.1 |  |  | 0.1 |
