Earnings Per Common Share (EPS) (Tables)

3 Months Ended

Mar. 31, 2014

The computations of basic and diluted EPS for the three months ended March 31 were as follows:

(Millions, except per share amounts)			2014			2013
Numerator:
	Basic and diluted:
		Net income	$	1,432	$	1,280
		Earnings allocated to participating share awards^(a)		(12)		(11)
		Net income attributable to common shareholders	$	1,420	$	1,269
Denominator:^(a)
	Basic: Weighted-average common stock			1,060		1,099
	Add: Weighted-average stock options^(b)			7		7
	Diluted			1,067		1,106

Basic EPS			$	1.34	$	1.15
Diluted EPS			$	1.33	$	1.15

The Company's unvested restricted stock awards, which include the right to receive non-forfeitable dividends or dividend equivalents, are considered participating securities. Calculations of EPS under the two-class method exclude from the numerator any dividends paid or owed on participating securities and any undistributed earnings considered to be attributable to participating securities. The related participating securities are similarly excluded from the denominator.
For the three months ended March 31, 2014 and 2013, the dilutive effect of unexercised stock options excludes 0.2 million and 0.9 million of options, respectively, from the computation of EPS because inclusion of the options would have been anti-dilutive.
