Net loss per share of Common Stock

Loss per Share

 Basic loss per share is computed by dividing net loss by the weighted-average number of shares of common stock outstanding during the period.  Diluted loss per share is calculated by including the additional shares of common stock issuable upon the conversion of convertible debt and the exercise of outstanding options and warrants, using the treasury stock method.  The following table lists the potentially dilutive equity instruments, each convertible into one share of common stock, used in the calculation of diluted loss per share for the periods presented:
