Earnings per share

6 Months Ended

Jun. 30, 2017

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, as determined using the treasury stock method (collectively, dilutive securities).

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



	Three months ended June 30,				Six months ended June 30,
	2017		2016		2017		2016
Income (Numerator):
Net income for basic and diluted EPS	$	2,151	$	1,870	$	4,222	$	3,770

Shares (Denominator):
Weighted-average shares for basic EPS	734		751		736		753
Effect of dilutive securities	4		5		4		6
Weighted-average shares for diluted EPS	738		756		740		759

Basic EPS	$	2.93	$	2.49	$	5.74	$	5.01
Diluted EPS	$	2.91	$	2.47	$	5.71	$	4.97

For the three and six months ended June 30, 2017 and 2016, the number of anti-dilutive employee share-based awards excluded from the computation of diluted EPS was not significant.
