Earnings Per Share [Abstract]

Earnings per Share

Earnings per Share

Basic earnings per share for all periods presented equals net income divided by the weighted average number of our shares outstanding during the period including participating securities. Diluted earnings per share is computed by dividing net income by the weighted average number of our shares outstanding during the period including participating securities, adjusted for the dilutive effect of our stock options, restricted shares and performance units.

The following discloses basic and diluted weighted average shares outstanding:

	Three Months Ended March 31,
(Shares in millions)	2015	2014
Basic and diluted weighted average shares outstanding	778	776

Our basic and diluted weighted average shares outstanding for the periods presented are equivalent due to the net loss attributable to shareholders. Diluted weighted average shares outstanding for the three months ended March 31, 2015 and 2014 exclude potential shares for stock options, restricted shares and performance units outstanding as we have net losses for that period and their inclusion would be anti-dilutive.

The following table discloses the number of anti-dilutive shares excluded:
