28. Earnings per share

Below is a reconciliation between the weighted-average number of common shares outstanding and the diluted weighted-average number of common shares.

(ii) Potential ordinary shares arising from the Group's share-based incentive plans (Note 29) have been included in the calculation of diluted earnings per share; their effect is not significant.

(a) Basic

Basic earnings per share amounts are calculated in accordance with IAS 33 “Earning per share” by dividing the profit attributable to equity holders of the Group by the weighted average number of common shares outstanding during the year, excluding ordinary shares purchased by the Group and held as treasury shares

(b) Diluted

Diluted earnings per share amounts are calculated by adjusting the weighted average number of common shares outstanding to assume conversion of all dilutive potential shares.

(i) Given that the result for the year showed losses, there is no diluted effect of such result.
