(13) Earnings Per Share

Basic earnings per share (“EPS”) is computed by dividing net income attributable to common shareholders by the weighted average number of shares outstanding during the applicable period. Diluted EPS reflects the potential dilution that could occur if all outstanding share options were exercised for, and all outstanding RSUs and PSUs were converted into, common shares. Potentially dilutive share options, RSUs and PSUs that were anti-dilutive under the treasury stock method were excluded from the computation of diluted EPS.

A reconciliation of the numerator and denominator of basic EPS with that of diluted EPS during 2022, 2021 and 2020 is presented as follows:


Share amounts in thousands	2022		2021		2020
