Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Income Tax Provision. Our income tax provision for quarterly interim periods is based on an estimated annual effective income tax rate calculated separately from the effect of significant, infrequent or unusual items. Our total income tax expense, including discontinued operations, was $5.2 million and $1.8 million for the three and nine months ended June 30, 2016, respectively, compared to a tax benefit of $0.1 million and $0.7 million for the three and nine months ended June 30, 2015, respectively. The change in our income tax expense was primarily driven by (1) the level of income or loss earned during the respective periods; (2) valuation allowance changes recorded during the previous fiscal year periods that are no longer recorded in the current fiscal year periods due to the release of a significant portion of our valuation allowance during the fourth quarter of our fiscal 2015 (see below); and (3) the timing of recognizing certain tax credits. Deferred Tax Assets and Liabilities. The Company continues to evaluate its deferred tax assets each period to determine if a valuation allowance is required based on whether it “is more likely than not” that some portion of the deferred tax assets would not be realized. As of September 30, 2015 and again as of June 30, 2016, we concluded that it is more likely than not that a substantial portion of our deferred tax assets will be realized. As of June 30, 2016, our conclusions on the valuation allowance of $57.7 million and Section 382 limitations related to our deferred tax assets remain consistent with the determinations we made during the period ended September 30, 2015 and are based on similar company specific and industry factors to those discussed in our 2015 Annual Report (refer to Note 13 to the audited consolidated financial statements within our 2015 Annual Report). Miscellaneous Tax Matters. In the normal course of business, we are subject to audits by federal and state tax authorities regarding various tax liabilities. The statute of limitations for our major tax jurisdictions remains open for examination for fiscal years 2007 and subsequent years.
