We calculate basic earnings per common share by dividing net loss attributable to common shareholders 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 common share awards, and the related impact on earnings, are considered when calculating diluted earnings per share. The calculation of basic and diluted earnings per share is as follows:
