| (b) | Diluted |
Diluted earnings per share is calculated by adjusting the weighted average number of ordinary shares outstanding to assume conversion of all dilutive potential ordinary shares.
The Company has dilutive potential ordinary shares from share options. The number of shares that would have been issued assuming the exercise of the share options less the number of shares that could have been issued at fair value (determined as the average market price per the Company’s A share for year ended 31 December 2017) for the same total proceeds is the number of shares issued for no consideration. The resulting number of shares issued for no consideration is included in the weighted average number of ordinary shares as the denominator for calculating diluted earnings per share.
The calculation of the diluted earnings per share for year ended 31 December 2015,2016 and 2017 was shown as:
