Generally, basic net (loss)/income per share is computed using the weighted average number of ordinary shares outstanding during the respective year. Diluted net (loss)/income per share is computed using the weighted average number of ordinary shares and dilutive potential ordinary shares outstanding during the respective year. The potentially dilutive ordinary shares included RSUs and options or Senior Preferred Shares to purchase or convert to ordinary shares of 74,896,940, 54,785,705 and 110,477,513 for the years ended December 31, 2019, 2020 and 2021 on a weighted average basis, respectively. They were not included in the calculation of diluted net loss per share in 2019 and 2020 presented where their inclusion would be anti-dilutive.

1-to-500 share split concurrent with the completion of IPO in May 2019 was accounted for on a retrospective basis for the calculation of basic and diluted loss per share as if they were completed at the inception of the Company.Basic and diluted (loss)/income per share are not reported separately for different classes of ordinary shares as each class of shares had the same rights to profits and losses.
