In the third quarter ended June 30, 2011, the Company recognized a $2.6 million income tax charge to provide a valuation allowance against its deferred tax assets due to the uncertainty of future realization. The establishment of such valuation allowance was determined to be appropriate during the period due to updated judgments of future results in light of the Company's operating losses since fiscal year 2010 and the inherent uncertainties of predicting future operating results in periods over which such net tax differences become deductible.
