Shares held for share incentive scheme purpose have been treated as treasury shares. Accordingly, for purpose of calculation of loss per share, the issued and outstanding number of ordinary shares as at December 31, 2020, 2021 and 2022, taking into account the shares held for share incentive scheme purpose, were 1,104,233,317 shares, 1,109,938,973 shares, 1,089,589,125 shares, respectively.

The effects of all outstanding share options granted under the Share Option Scheme and Restricted Share Units Scheme (Note 26) for the years ended December 31, 2020, 2021 and 2022, have been excluded from the computation of diluted loss per share as their effects would be anti-dilutive. Accordingly, dilutive loss per share for the years ended December 31, 2020, 2021 and 2022 were the same as basic loss per share for the years.
