31 Earnings per share
Basic earnings per share are calculated by dividing net profit by the weighted average number of outstanding Snam shares during the year, excluding treasury shares.
Diluted earnings per share are calculated by dividing net profit by the weighted average number of outstanding shares during the period, excluding treasury shares, increased by the number of shares which could potentially be issued following the allocation or disposal of treasury shares held under stock option plans. As at 31 December 2014, no stock option plans existed, and therefore basic earnings per share was equal to diluted earnings per share.
The weighted average number of outstanding shares used to calculate diluted earnings per share is 3,384,657,230 (3,379,543,289 for 2013).
