Earnings per Share

Earnings per Share

The computations of basic and diluted earnings per share were as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2022		2021		2022		2021
	(in millions, except per share amounts)
Numerator:
Net income	$	548	$	1,031	$	2,065	$	2,059
Denominator:
Basic: Weighted-average common shares outstanding	110.5		116.4		112.1		118.2
Effect of potentially dilutive nonqualified stock options and other share-based awards	2.2		2.8		2.3		2.7
Diluted: Weighted-average common shares outstanding	112.7		119.2		114.4		120.9
Earnings per share:
Basic	$	4.96	$	8.86	$	18.42	$	17.42
Diluted	$	4.86	$	8.65	$	18.05	$	17.03

The calculation of diluted earnings per share excludes the incremental effect of nil and nil options for the three months ended September 30, 2022 and 2021, respectively, and 0.2 million and nil options for the nine months ended September 30, 2022 and 2021, respectively, due to their anti-dilutive effect.
