Since there was a net loss for the three months ended June 30, 2012, incremental shares of 140 were not included in the computation of diluted loss per common share, as their effect would have been anti-dilutive. There were no anti-dilutive shares excluded from the calculation of diluted earnings per share for the three and nine months ended June 30, 2013 and the nine months ended June 30, 2012.
