Earnings per share

6 Months Ended

Jun. 30, 2016

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 principally shares that may be issued under our stock option, restricted stock and performance unit awards, 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				Six months ended
	June 30,				June 30,
	2016		2015		2016		2015
Income (Numerator):
Net income for basic and diluted EPS	$	1,870	$	1,653	$	3,770	$	3,276

Shares (Denominator):
Weighted-average shares for basic EPS	751		760		753		761
Effect of dilutive securities	5		8		6		8
Weighted-average shares for diluted EPS	756		768		759		769

Basic EPS	$	2.49	$	2.18	$	5.01	$	4.30
Diluted EPS	$	2.47	$	2.15	$	4.97	$	4.26

For the three and six months ended June 30, 2016 and 2015, the number of anti-dilutive employee share-based awards excluded from the computation of diluted EPS was not significant.
