EARNINGS PER COMMON SHARE (EPS)

The computations of basic and diluted EPS for the years ended December 31 were as follows:


(Millions, except per share amounts)	2020		2019		2018

Denominator:(a)

Add: Weighted-average stock options(b)	1		2		3
Diluted	806		830		859
Basic EPS	$	3.77	$	8.00	$	7.93

(a)Our 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.

(b)The dilutive effect of unexercised stock options excludes from the computation of EPS 0.5 million, 0.2 million and 0.7 million of options for the years ended December 31, 2020, 2019 and 2018, respectively, because inclusion of the options would have been anti-dilutive.
