Earnings Per Share [Abstract] |
Earnings per share | Earnings per share. Basic earnings per share (EPS) attributable to Stewart is calculated by dividing net income attributable to Stewart by the weighted-average number of shares of Common Stock outstanding during the reporting periods. To calculate diluted EPS, the number of shares is adjusted to include the number of additional shares that would have been outstanding if restricted units were vested and issued and stock options were exercised. In periods of net losses, dilutive shares are excluded from the calculation of the diluted EPS and diluted EPS is computed in the same manner as basic EPS. The calculation of the basic and diluted EPS is as follows:
