Earnings Per Share [Abstract]

Earnings per Share

(Loss) Earnings per Share

Basic (loss) earnings per share is based on the weighted-average number of common shares outstanding during the period. Diluted net (loss) earnings per share is based on the number of shares used for the basic (loss) earnings per share calculation, adjusted for the dilutive effect of share options, restricted share equivalent (“RSE”) and performance restricted share equivalent (“PRSE”) awards.

The following is the reconciliation between the number of weighted-average shares used in the basic and diluted net (loss) earnings per share calculation:    

	Three Months Ended December 31,
	2024	2023
Basic weighted-average shares outstanding	48.7	50.1
Effect of dilutive securities:
Options, RSE and PRSE awards	—	0.4
Total dilutive securities	—	0.4
Diluted weighted-average shares outstanding	48.7	50.5

For the three months ended December 31, 2024, the calculation of diluted weighted-average shares outstanding excludes 0.5 of options, RSE and PRSE awards that would have otherwise been dilutive, because the Company reported a net loss.

The following weighted-average common shares were excluded from the calculation of diluted net (loss) earnings per share because the effect of including these awards was antidilutive.

	Three Months Ended December 31,
	2024	2023
Options, RSE and PRSE awards	1.4	1.9
