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:

	Three Months Ended June 30,		Six Months Ended June 30,
	2022	2021	2022	2021
Basic weighted-average shares outstanding	135.2	139.8	135.1	140.6
Effect of dilutive securities(1)	1.6	1.9	1.7	1.8
Diluted weighted-average shares outstanding(2)	136.8	141.7	136.8	142.4

(1)The dilutive effect of outstanding stock options, restricted stock units, performance share units and Coworker Stock Purchase Plan 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 both the three and six months ended June 30, 2022 and 2021 as their inclusion would have had an anti-dilutive effect.
