Earnings per share

9 Months Ended

Sep. 30, 2022

The computation of basic EPS is based on the weighted-average number of our common shares outstanding. The computation of diluted EPS is based on the weighted-average number of our common shares outstanding and dilutive potential common shares, which primarily include shares that may be issued under our stock option, restricted stock and performance unit award programs (collectively, dilutive securities), as determined by using the treasury stock method.

The computations for basic and diluted EPS were as follows (in millions, except per-share data):


	Three months ended September 30,				Nine months ended September 30,
	2022		2021		2022		2021
Income (Numerator):
Net income for basic and diluted EPS	$	2,143	$	1,884	$	4,936	$	3,994

Shares (Denominator):
Weighted-average shares for basic EPS	535		567		539		572
Effect of dilutive securities	3		3		3		4
Weighted-average shares for diluted EPS	538		570		542		576

Basic EPS	$	4.01	$	3.32	$	9.16	$	6.98
Diluted EPS	$	3.98	$	3.31	$	9.11	$	6.93

For the three and nine months ended September 30, 2022 and 2021, the number of antidilutive employee stock-based awards excluded from the computation of diluted EPS was not significant.
