Earnings per share [abstract]

Earning per share

9Earnings per share

Basic earnings per ordinary share is calculated by dividing the profit attributable to ordinary shareholders of the parent company by the

weighted average number of ordinary shares outstanding, after deducting own shares held. Diluted earnings per ordinary share is calculated by

dividing the basic earnings, which require no adjustment for the effects of dilutive potential ordinary shares, by the weighted average number

of ordinary shares outstanding, excluding own shares held, plus the weighted average number of ordinary shares that would be issued on

conversion of dilutive potential ordinary shares.
