Net Earnings Per Share

3 Months Ended

Mar. 31, 2023

Net earnings per share were computed as follows:


	Three months ended March 31,
		2023		2022
		(in millions, except per share amounts)
Net earnings attributable to common stockholders		$	560	$	883
Basic earnings per common share:
Weighted-average common shares outstanding		196.2		208.6
Net earnings attributable to common stockholders		$	2.86	$	4.23
Diluted earnings per common share:
Weighted-average common shares outstanding		196.2		208.6
Dilutive common shares—stock-based awards		0.7		1.3
Diluted weighted-average common shares outstanding		196.9		209.9
Net earnings attributable to common stockholders		$	2.85	$	4.21

Diluted earnings per common share is calculated using weighted-average common shares outstanding, including the dilutive effect of stock-based awards as determined under the treasury stock method. In the computation of diluted earnings per common share, potentially dilutive stock-based awards are excluded if the effect of their inclusion is anti-dilutive. Shares for anti-dilutive stock-based awards not included in the computation of diluted earnings per common share were zero in both the three months ended March 31, 2023 and 2022.
