12. Net Income per Share

Basic net income per share is computed using the weighted average number of the ordinary shares outstanding during the period. Options and RSUs 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 years ended December 31, 2019, 2020 and 2021, options to purchase ordinary shares and RSUs of 1.0 million, 0.7 million and 1.4 million were recognized as dilutive factors and included in the calculation of diluted net income per share, respectively. For the years ended December 31, 2019, 2020 and 2021, options and RSUs which were anti-dilutive and excluded from the calculation of diluted net income per share were 0.4 million, 0.9 million and 0.4 million, respectively. For each of the years ended December 31, 2019, 2020 and 2021, 6.8 million shares convertible from the convertible debt were anti-dilutive and excluded from the calculation of diluted net income per share.

The following table sets forth the computation of basic and diluted net income per share for the periods presented:
