18.  Loss Per Common Share

Basic loss per common share is computed by dividing net loss by the weighted average number of common shares outstanding for the period.  Diluted loss per common share is computed by dividing net loss by the weighted average number of common shares outstanding, adjusted for shares that would be assumed outstanding after warrants and stock options vested under the treasury stock method.  At December 31, 2014 and 2013, outstanding warrants convertible into 75,300 and 161,800 shares, respectively, of Common Stock were excluded from the calculation of diluted loss per share because their impact would have been anti-dilutive.  At December 31, 2014 and 2013, there were outstanding stock options to purchase 40 and 60 shares of Common Stock, respectively, which were also excluded from the calculation of diluted loss per share because their impact would have been anti-dilutive.
