Earnings Per Share [Abstract] |
Earnings (Loss) per Share and Equity Transactions | Earnings (Loss) Per Share and Equity Transactions Basic earnings (loss) per share ("EPS") are computed using the two-class method by dividing net income (loss) by the weighted average number of common shares outstanding for the period (the "common shares"). The restricted share awards issued pursuant to the Incentive Award Plan are deemed to be participating securities. Diluted EPS is computed using the treasury method if more dilutive, by dividing net income (loss) by the common shares plus potential common shares issuable upon exercising options or other contracts. The following table reconciles the amounts used in calculating basic and diluted income (loss) per share:
