Weighted Average Common Shares	6 Months Ended
Weighted Average Common Shares	Jun. 30, 2020
Earnings Per Share [Abstract]
Weighted Average Common Shares	Weighted Average Common Shares 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 June 30, 2020 and 2019, 346 and 68 unvested common shares, respectively, and for the six months ended June 30, 2020 and 2019, 234 and 18 unvested common shares, respectively, were not included in the calculation of diluted earnings per share because to do so would have been antidilutive.
