Loss Per Common Share

Loss Per Common Share

Basic and diluted loss per common share is computed by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net loss per common share is the same as basic net loss per common share for the three and nine months ended September 30, 2016 and 2015, because the effect of the potential common stock equivalents would be antidilutive due to the Company’s net loss position for these periods. Antidilutive securities consist only of stock options outstanding of 15,487,348 and 13,678,899 as of September 30, 2016 and 2015, respectively.
