[1] Diluted basic earnings per share from discontinued operations - US dollar Diluted basic earnings per share is calculated on the basis of profit attributable to ordinary shareholders from discontinued operations of $20.5 million (2012: $362.2 million and 2011: $340.8 million) and 742,606,726 shares, being the diluted number of ordinary shares in issue in fiscal 2013 (fiscal 2012: 730,723,950 and fiscal 2011:730,787,498).
[2] Basic earnings per share from discontinued operations - US dollar Basic earnings per share is calculated by dividing the profit attributable to ordinary shareholders from discontinued operations of $20.5 million (2012: $362.2 million and 2011: $340.8 million) by the weighted average number of ordinary shares in issue in fiscal 2013 of 742,606,726 (fiscal 2012: 727,459,457 and fiscal 2011: 722,376,228).
[3] Dilutive securities comprise the dilutive effect of share options. Refer note 18 for details of share option schemes. In 2013, due to the loss from continuing operations, the effect of dilutive securities was not considered in the diluted (loss)/earnings per share calculation.
