Earnings Per Share [Abstract] |
Weighted Average Common Shares | Weighted Average Common Shares (share amounts in thousands)We calculate basic earnings per common share by dividing net income (loss) by the weighted average number of our common shares outstanding during the period. We calculate diluted earnings per share using the more dilutive of the two class method or the treasury stock method. Unvested share awards and other potentially dilutive common shares, and the related impact on earnings, are considered when calculating diluted earnings per share. For the three months ended March 31, 2021 and 2020, 20 and 123 unvested common shares, respectively, were not included in the calculation of diluted earnings per share because to do so would have been antidilutive.
