There were no anti-dilutive shares excluded from the calculation of diluted earnings per share for the three months ended June 30, 2011 and nine months ended June 30, 2011, and 2010. Since there was a net loss for the three months ended June 30, 2010, incremental shares were not included in the computation of diluted loss per common share, as their effect would have been anti-dilutive.
