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 benefit, including discontinued operations, was $2.6 million for the three months ended December 31, 2016, compared to income tax expense of $0.6 million for the three months ended December 31, 2015. Our current quarter income tax benefit was primarily driven by (1) the loss in earnings from continuing operations in the current period and (2) the Company's completion of work necessary to claim an additional $1.2 million in tax credits, which were recorded in the current quarter but related to our fiscal 2016. The tax expense for the three months ended December 31, 2015 was primarily driven by our earnings from continuing operations. 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 these deferred tax assets will not be realized. As of September 30, 2016 and again as of December 31, 2016, we concluded that it is more likely than not that a substantial portion of our deferred tax assets will be realized. As of December 31, 2016, our conclusions on the valuation allowance of $66.3 million and Internal Revenue Code Section 382 limitations related to our deferred tax assets remain consistent with the determinations we made during the period ended September 30, 2016 and are based on similar company specific and industry factors to those discussed in Note 13 to the audited consolidated financial statements within our 2016 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. Certain state income tax returns for various fiscal years are under routine examination. The statute of limitations for our major tax jurisdictions remains open for examination for our fiscal 2007 and subsequent years.
