13. Net Loss per Common Share

Basic loss per share is computed by dividing net loss, adjusted for the accretion of preferred dividends, for the period by the weighted average number of common shares outstanding during the period. Diluted loss per share is computed by dividing net loss for the period by the weighted average number of common shares outstanding during the period plus the dilutive effect, if any, of outstanding stock options, RSUs, PSUs, and warrants using the treasury stock method. The following table sets forth the computation of basic net loss per share:
