Earnings Per Share

Basic EPS is computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding during the period. The computation of diluted EPS is similar to the computation of basic EPS except that the denominator is increased to include the number of additional common shares that would have been outstanding if dilutive potential common shares had been issued. Dilutive potential common shares include the effect of outstanding stock options and unvested restricted stock awards and units. EPS under the basic and diluted computations is as follows:


	Three Months Ended September 30,				Nine Months Ended September 30,
	2011		2010		2011		2010
Net income available to common stockholders ⁽¹⁾	$	220	$	124	$	701	$	335

Common stock equivalent shares related to stock incentive plans		1		2		3		3

Weighted-average common shares outstanding — diluted ⁽²⁾		1,229		1,194		1,216		1,192

Diluted EPS	$	.18	$	.10	$	.57	$	.28

⁽¹⁾	Net income available to participating securities (unvested restricted shares) was not material for the third quarters and first nine months of 2011 or 2010.

⁽²⁾	Antidilutive stock options and restricted stock awards excluded from the calculation of diluted EPS totaled 50 million and 49 million shares for the third quarters of 2011 and 2010, respectively, and 48 million and 40 million shares for the first nine months of 2011 and 2010, respectively.
