Earnings per share

6 Months Ended

Jun. 30, 2015

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 awards and restricted stock and performance unit awards, 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,
	2015		2014		2015		2014
Income (Numerator):
Net income for basic and diluted EPS	$	1,653	$	1,547	$	3,276	$	2,620

Shares (Denominator):
Weighted-average shares for basic EPS	760		759		761		758
Effect of dilutive securities	8		9		8		10
Weighted-average shares for diluted EPS	768		768		769		768

Basic EPS	$	2.18	$	2.04	$	4.30	$	3.46
Diluted EPS	$	2.15	$	2.01	$	4.26	$	3.41

For the three and six months ended June 30, 2015 and 2014, the number of anti-dilutive employee stock-based awards excluded from the computation of diluted EPS was not significant.
