Earnings Per Common Share

EPS is computed using the two-class method. Preferred stock dividends, and undistributed earnings and dividends allocated to participating securities are subtracted from net income in determining net income available to common stockholders. 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, if dilutive, the effect of outstanding stock options and non-vested restricted stock units. EPS under the basic and diluted computations is as follows:



Year Ended December 31,	2017			2016			2015
Net income	$	2,354		$	1,889		$	1,447
Preferred stock dividends and other ⁽¹⁾	(174		)	(143		)	(83		)
Net income available to common stockholders	$	2,180		$	1,746		$	1,364
Weighted-average common shares outstanding — basic	1,339			1,324			1,315
Common stock equivalent shares related to stock incentive plans	14			10			12
Weighted-average common shares outstanding — diluted ⁽²⁾	1,353			1,334			1,327
Basic EPS	$	1.63		$	1.32		$	1.04
Diluted EPS	$	1.61		$	1.31		$	1.03

⁽¹⁾ Includes preferred stock dividends and undistributed earnings and dividends allocated to non-vested restricted stock units.

⁽²⁾ Antidilutive stock options and restricted stock units excluded from the calculation of diluted EPS totaled 15 million, 26 million, and 23 million shares in 2017, 2016, and 2015, respectively.
