16. Earnings (Loss) per Common Share

Basic earnings or loss per share attributable to the Company’s common stockholders is computed by dividing net earnings or loss attributable to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings or loss per share attributable to common stockholders presents the dilutive effect, if any, on a per share basis of potential common shares (such as restricted stock units) as if they had been vested or converted during the periods presented.  No such items were included in the computation of diluted loss per share for the year ended December 31, 2018 because the Company incurred a net loss in the period and the effect of inclusion would have been anti-dilutive. All of the shares outstanding and per share amounts have been retroactively adjusted to reflect the stock-split in the Company’s consolidated financial statements.
