Earnings per Share

9 Months Ended

Sep. 30, 2016

Basic earnings per share for all periods presented equals net income (loss) divided by the weighted average number of our shares outstanding during the period including participating securities. Diluted earnings (loss) per share is computed by dividing net income (loss) 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 table presents our basic and diluted weighted average shares outstanding for the third quarter and the nine months of 2016 and 2015:



	Three Months Ended September 30,		Nine Months Ended September 30,
(Shares in millions)	2016	2015	2016	2015
Basic and Diluted weighted average shares outstanding	899	779	871	778

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 third quarter and the nine months of 2016 and 2015 exclude potential shares for stock options, restricted shares, performance units and exchangeable notes outstanding as we have net losses for those periods, and their inclusion would be anti-dilutive. The following table presents the number of anti-dilutive shares excluded for the third quarter and the nine months of 2016 and 2015:



	Three Months Ended September 30,		Nine Months Ended September 30,
(Shares in millions)	2016	2015	2016	2015
Anti-dilutive potential shares due to net loss	166	3	71	3
