Earnings per share
Earnings per share for the first quarters of 2013 and 2014 were calculated on the basis of the number of shares outstanding at the ends of the respective periods. They are derived solely from continuing operations. Since there are currently no equity instruments in issue that could dilute earnings per share, basic and diluted earnings per share are identical. For more information about equity instruments that could dilute earnings per share in the future, readers are referred to the notes to the consolidated financial statements as of December 31, 2013.
