Net Income (Loss) Per Share |
Net Income (Loss) Per Share | 12. Net Income (Loss) Per Share Basic net income (loss) per share is computed using the weighted average number of the ordinary shares outstanding during the period. Options, RSUs and preferred shares are not considered outstanding in the computation of basic earnings per share (“EPS”). Diluted EPS is computed using the weighted average number of ordinary shares and potential ordinary shares outstanding during the period under the treasury stock method. For the year ended December 31, 2014, options to purchase ordinary shares and RSUs that were anti-dilutive and excluded from the calculation of diluted net loss per share were 17.8 million. For the years ended December 31, 2015 and 2016, options to purchase ordinary shares and RSUs of 9.8 million and 8.1 million, respectively, were recognized as dilutive factors and included in the calculation of diluted net income per share. For the years ended December 31, 2014, 2015 and 2016, no preferred shares were included in the calculation of diluted net income (loss) per share of the Group, as all preferred shares converted into ordinary shares during the Group’s IPO in April 2014. The following table sets forth the computation of basic and diluted net income (loss) per share for the periods indicated:
