| Earnings Per Share [Abstract] | ||||||||||||||||||||||||||||||||||||||||||||||
| Earnings per share |
Basic income (loss) per share is calculated by dividing the net income (loss) attributable to common shares by the weighted average number of common shares outstanding during the period. Diluted income (loss) per share adjusts basic income (loss) per share for the effects of potentially dilutive common shares, if the effect is not antidilutive.
