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,
						2021						2020						2019
Basic weighted-average shares outstanding						138.5						142.6						145.1
Effect of dilutive securities (1)						2.0						2.2						2.7
Diluted weighted-average shares outstanding (2)						140.5						144.8						147.8

(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 0.1 million potential common shares excluded from diluted weighted-average shares outstanding for the years ended December 31, 2021, 2020 and 2019, respectively, as their inclusion would have had an anti-dilutive effect.
