Basic and Diluted Loss per Share
 
 
Basic loss per common share is computed using the weighted average number of common shares outstanding during the period.  Diluted loss per share is computed using the weighted average number of common shares and potential dilutive common shares that were outstanding during the period.  Potential dilutive common shares consist of outstanding stock options, outstanding stock warrants, and convertible preferred stock.
 
 
The following table sets forth the computation of basic and diluted loss per share:

Options and warrants to purchase 1,897,025 shares of common stock for the three months and six months ended June 30, 2015, respectively, were not included in the denominator for diluated net loss per share because their effect would be antidilutive or because the shares were deemed contingently issuable.  Options and warrants to purchase 1,502,987 shares of common stock for the three months and six months ended June 30, 2014, respectively, were not included in the denominator for diluted net loss per share because their effect would be antidilutive or because the shares were deemed contingently issuable.
