(b)

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. For the years ended December 31, 2020, 2021 and 2022 the Group has four categories of potential dilutive ordinary shares: convertible promissory note (refer to Note 34), optionally convertible promissory notes (refer to Note 35), share options and PSUs (refer to Note 43).

For the year ended December 31, 2020, potential ordinary shares issuable upon conversion of optionally convertible promissory notes were not included in the calculation of diluted earnings, as the effect would have been anti-dilutive.

For the year ended December 31, 2021, all four categories of potential dilutive ordinary shares are included in the calculation of diluted earnings per share.

For the year ended December 31, 2022, two categories of potential dilutive ordinary shares are included in the calculation of diluted earnings per share: share options and PSUs. Potential ordinary shares issuable upon conversion of optionally convertible promissory notes and convertible promissory note were not included in the calculation of diluted earnings per share, as the effect would have been anti-dilutive.
