Earnings Per Share [Abstract]

Earnings (Loss) per Share

Basic earnings per share is based on the average number of common stock outstanding during the period. Diluted earnings per share is based on the average number of shares used for the basic earnings per share calculation, adjusted for the dilutive effect of share options, RSE, and PRSE awards.

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

	Fiscal Year
	2025	2024	2023
Basic weighted-average shares outstanding	47.5	49.7	51.2
Effect of dilutive securities:
Options, RSE and PRSE awards	0.1	0.4	0.6
Total dilutive securities	0.1	0.4	0.6
Diluted weighted-average shares outstanding	47.6	50.1	51.8

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

	Fiscal Year
	2025	2024	2023
Options, RSE and PRSE awards	1.6	1.3	1.2
