Earnings per ordinary share | 9. Earnings per ordinary share Basic earnings per ordinary share is calculated by dividing the profit for the year available for IHG equity holders by the weighted average number of ordinary shares, excluding investment in own shares, in issue during the year. Diluted earnings per ordinary share is calculated by adjusting basic earnings per ordinary share to reflect the notional exercise of the weighted average number of dilutive ordinary share awards outstanding during the year. Adjusted earnings per ordinary share is disclosed in order to show performance undistorted by exceptional items, to give a more meaningful comparison of the Group’s performance.
