Earnings per share

Earnings per share for the first quarters of 2011 and 2012 were calculated on the basis of the number of shares outstanding as of the respective closing dates. They are derived solely from continuing operations. There were no accounting change effects to be considered. 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, 2011.
