Diluted earnings per common share attributable to Comcast Corporation shareholders (“diluted EPS”) considers the impact of potentially dilutive securities using the treasury stock method. Our potentially dilutive securities include potential common shares related to our stock options and our restricted share units (“RSUs”). Diluted EPS excludes the impact of potential common shares related to our stock options in periods in which the combination of the option exercise price and the associated unrecognized compensation expense is greater than the average market price of our Class A common stock or our Class A Special common stock, as applicable. The amount of potential common shares related to our share-based compensation plans that were excluded from dilute d EPS because their effect would have been antidilutive was not material for 2014, 2013 and 2012.
