Earnings (Loss) Per Share [Abstract] |
Earnings (loss) per share | 14. Earnings (loss) per share The calculation of basic earnings (loss) per share is based on the income (loss) attributable to ordinary shareholders of the Company and weighted-average number of ordinary shares outstanding for the years ended December 31, 2021, 2022 and 2023. Diluted earnings (loss) per share is computed using the weighted average number of ordinary shares and dilutive potential ordinary shares outstanding during the respective periods. For the year ended December 31, 2023, the options granted under the 2022 share incentive plan for a weighted average number of 312,386 shares could potentially dilute earnings (loss) per share but were not included in the computation of diluted net loss per share due to their antidilutive effects resulted from net loss. The following reflects the income and share data used in the basic and diluted earnings (loss) per ordinary share computations:
