Our potentially dilutive securities include potential common shares related to our stock options and our restricted share units (“RSUs”). Diluted earnings per common share attributable to Comcast Corporation shareholders (“diluted EPS”) considers the impact of potentially dilutive securities by using the treasury stock method.

For the three and nine months ended September 30, 2014, diluted EPS excluded 17 million and 13 million, respectively, of potential common shares related to our share-based compensation plans, because the inclusion of the potential common shares would have had an antidilutive effect. For the three and nine months ended September 30, 2013, diluted EPS excluded 18 million and 13 million, respectively, of potential common shares.
