Earnings Per Share [Abstract]

9. Net Loss Per Share

Basic earnings and loss per share are computed by dividing the net income or loss applicable to common shares by the weighted average number of common shares outstanding during the period.  Diluted earnings per share is computed using the weighted average number of common shares and, if dilutive, potential common shares outstanding during the period.  Potential common shares consist of the incremental common shares issuable upon the exercise of stock options (using the treasury stock method) and the conversion of the Company’s convertible preferred stock and warrants (using the if-converted method).  Diluted loss per share excludes the shares issuable upon the conversion of preferred stock and the exercise of stock options and warrants from the calculation of net loss per share if their effect would be antidilutive.

 Securities that could potentially dilute earnings per share in the future that were not included in the computation of diluted loss per share at June 30, 2013 and 2012, are as follows:
