Note 4.   Net Loss per Common Share

Basic earnings per share is calculated based upon the net income (loss) available to common shareholders divided by the weighted average number of common shares outstanding during the period.  Diluted earnings per share is calculated after adjusting the denominator of the basic earnings per share computation for the effects of all dilutive potential common shares outstanding during the period. The dilutive effects of preferred stock, options and, warrants and their equivalents are computed using the treasury stock method.

For the three months ended June 30, 2012 and the six months ended June 30, 2013 and 2012, diluted loss per common share was the same as basic loss per common share as all options and warrants that were convertible into shares of the Company’s common stock were excluded from the calculation of diluted earnings per share as their effect would have been anti-dilutive. The total number of shares of common stock issuable upon exercise of warrants and equity awards for the periods ended June 30, 2013 and 2012 were 17,908,724 and 15,203,880, respectively.
