During the fiscal years ended September 30, 2012 and 2013, there were 1,546,207 and 1,728,042 weighted average shares of options outstanding, respectively, that were not included in the computation of diluted income (loss) per share because the options’ exercise prices were greater than the average market price of our common stock, and therefore, their effect would be anti-dilutive. For the fiscal year ended September 30, 2011, no options were included in the computation of diluted loss per share because we reported a net loss and the effect of their inclusion would have been anti-dilutive.
