Basic and diluted earnings per share

10          Basic and diluted earnings per share

​

Diluted earnings per share are calculated by adjusting the weighted average number of ordinary shares outstanding, assuming conversion of all potentially dilutive ordinary shares. As the Company has incurred a loss, all potentially dilutive ordinary shares would have an antidilutive effect, if converted, and thus have been excluded from the computation of loss per share.

​

The potentially dilutive ordinary shares are summarized below:

​
