Loss Per Common Share
Loss per common share is calculated using net loss for the year and the weighted average number of common shares outstanding for the year ended December 31, 2017 of 132,395,752 (2016 - 119,880,200; 2015 - 112,613,845). The effect of any potential exercise of our stock options and warrants outstanding during the year has been excluded from the calculation of diluted loss per common share, as it would be anti-dilutive.
