Earnings Per Share [Abstract]

Earnings per share

Earnings per share

The computation of basic earnings per share (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 include primarily 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 March 31,
	2020		2019
Income (Numerator):
Net income for basic and diluted EPS	$	1,825	$	1,992
Shares (Denominator):
Weighted-average shares for basic EPS	590		622
Effect of dilutive securities	4		4
Weighted-average shares for diluted EPS	594		626
Basic EPS	$	3.09	$	3.20
Diluted EPS	$	3.07	$	3.18

For the three months ended March 31, 2020 and 2019, the number of antidilutive employee stock-based awards excluded from the computation of diluted EPS was not significant.
