Net Loss Per Common Share
 
Basic net loss per common share is computed by dividing net loss by the weighted average number of common shares outstanding. Diluted net loss available to common stockholders per common share is computed by dividing net loss by the weighted average number of common shares and dilutive potential common share equivalents then outstanding. The Company’s potential dilutive common shares, which consist of shares issuable upon the exercise of stock options, have not been included in the computation of diluted net loss per share for all periods as the result would be anti-dilutive.
