| Earnings per share |
The Company presents basic earnings per share ("EPS") data for its common voting shares. Basic EPS is calculated by dividing the profit or loss attributable to common voting shareholders of the Company by the weighted average number of common voting shares outstanding during the period, adjusted for the Company's own shares held. Diluted EPS is computed similar to basic EPS except that the weighted average shares outstanding are increased to include additional shares for the assumed exercise of stock options and warrants, if dilutive. The number of additional shares is calculated by assuming that outstanding stock options and warrants were exercised and that the proceeds from such exercise were used to acquire common shares at the average market price during the reporting periods.
