15. Net Loss Per Common Share

 

Basic net loss per common share is computed based upon the weighted average common shares outstanding as defined by ASC No. 260, Earnings Per Share.  Diluted net loss per common share includes the dilutive effects of stock options, warrants and stock equivalents.  To the extent stock options, stock equivalents and warrants are antidilutive, they are excluded from the calculation of diluted net loss per share.  For the year ended December 31, 2014, 16,500,753 shares issuable upon the exercise of stock options and warrants were not included in the computation of diluted net loss per share because their inclusion would be antidilutive.  For the year ended December 31, 2013, 17,327,290 shares issuable upon the exercise of stock options and warrants were not included in the computation of diluted net loss per share because their inclusion would be antidilutive.

 

The following table provides a reconciliation of the numerator and denominator used in computing basic and diluted net loss per common share:
