Earnings Per Share [Abstract]

Earnings Per Share

13.  Earnings Per Share

The following is a reconciliation of weighted average shares for the basic and diluted shares computations (in millions):

	Three Months Ended
	March 31,
	2022		2021
Weighted average shares outstanding for basic net earnings per share		209.2		208.0
Effect of dilutive stock options and other equity awards		0.9		2.2
Weighted average shares outstanding for diluted net earnings per share		210.1		210.2

During the three-month periods ended March 31, 2022 and 2021, an average of 2.9 million options and 0.4 million options, respectively, to purchase shares of common stock were not included in the computation of diluted earnings per share because the effect would have been antidilutive.
