Basic earnings per common share are calculated by dividing net income (loss) by the weighted average number of common shares outstanding, which includes 21,413 shares of participating securities. Diluted earnings per share are calculated by dividing net income (loss) by the sum of the weighted average number of common shares outstanding plus the additional common shares that would have been outstanding if potentially dilutive securities had been issued.

The weighted average common shares outstanding for the diluted earnings per share calculation excludes consideration of 981,330 equivalent shares in the three months ended March 31, 2019, as these shares are anti-dilutive.
