Basic 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, 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):


	Three Months Ended				Nine Months Ended
	May 31, 2025		May 31, 2024		May 31, 2025		May 31, 2024
Net income	$	98.4	$	113.9	$	282.6	$	303.7
Basic weighted average shares outstanding	30.851		30.829		30.912		30.905
Common stock equivalents	0.714		0.648		0.761		0.515
Diluted weighted average shares outstanding	31.565		31.477		31.673		31.420
Basic earnings per share(1)	$	3.19	$	3.70	$	9.14	$	9.83
Diluted earnings per share(1)	$	3.12	$	3.62	$	8.92	$	9.67

Stock options, performance stock awards, and restricted stock awards that were excluded from the diluted earnings per share calculation as the effect of inclusion would have been antidilutive were immaterial for the three and nine months ended May 31, 2025 and May 31, 2024.
