Earnings Per Share [Abstract] |
Earnings Per Share Computations | Earnings Per Share Computations The Company applies the two-class method when computing its earnings per share ("EPS"), which requires that net income per share for each class of share be calculated assuming all of the Company's net income is distributed as dividends to each class of share based on their contractual rights. Basic EPS is computed by dividing net income available to ordinary shareholders by the weighted-average number of ordinary shares outstanding after excluding the ordinary shares to be repurchased using forward contracts. Diluted EPS includes the effects of share options, restricted share units, performance rights, performance shares, and share rights, if dilutive.
