Earnings Per Share [Abstract]

Schedule of Weighted Average Number of Shares

A reconciliation of basic weighted-average shares outstanding to diluted weighted-average shares outstanding is as follows:

	Year Ended December 31,
	2023	2022	2021
Basic weighted-average shares outstanding	134.6	135.2	138.5
Effect of dilutive securities (1)	1.7	1.8	2.0
Diluted weighted-average shares outstanding (2)	136.3	137.0	140.5

(1)The dilutive effect of outstanding stock options, restricted stock units, performance share units and Coworker Stock Purchase Plan (“CSPP”) units is reflected in the diluted weighted-average shares outstanding using the treasury stock method.

(2)There were fewer than 0.2 million potential common shares excluded from diluted weighted-average shares outstanding for the years ended December 31, 2023, 2022 and 2021, respectively. Inclusion of these common shares in diluted weighted average shares outstanding would have had an anti-dilutive effect.
