Earnings Per Share [Abstract]  
Earnings per share Earnings per share
Basic EPS is calculated by dividing net income by the weighted average number of our ordinary shares outstanding, which excludes 2,354,318, 2,429,442 and 3,007,752 shares of unvested restricted stock as of December 31, 2019, 2018 and 2017, respectively. For the calculation of diluted EPS, the weighted average of our ordinary shares outstanding for basic EPS is adjusted by the effect of dilutive securities provided under our equity compensation plans. The number of ordinary shares excluded from diluted shares outstanding was 163,067, 90,929 and 509,677 for the years ended December 31, 2019, 2018 and 2017, respectively, because the effect of including those shares in the calculation would have been anti-dilutive.
The computations of basic and diluted EPS for the years ended December 31, 2019, 2018 and 2017 were as follows:
