Earnings (Loss) Per Share

For purposes of this calculation, outstanding stock options, stock warrants, and unvested restricted stock units are considered common stock equivalents using the treasury stock method, and are the only such equivalents outstanding.  For all periods presented all equivalent units outstanding were anti-dilutive.  As of September 30, 2013, options to purchase approximately 726,000 shares of common stock, warrants to purchase 44,400 shares of common stock and approximately 42,700 unvested restricted stock units were excluded from the calculation as their impact would be anti-dilutive.
