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 provision, including discontinued operations, was a tax expense of $5.7 million and a tax benefit of $1.3 million for the three and nine months ended June 30, 2017, respectively, compared to an income tax expense of $5.2 million and $1.8 million for the three and nine months ended June 30, 2016, respectively. Our current fiscal year income tax benefit was primarily driven by (1) the loss incurred from continuing operations; and (2) the Company's completion of work necessary to claim an additional $1.3 million in tax credits, which were recorded in the current fiscal year but related to our fiscal 2016; partially offset by (3) several discrete tax expenses, including a prior period balance due for one of our operating jurisdictions based on new information received. The tax expense for the nine months ended June 30, 2016 was primarily driven by our earnings from continuing operations offset by the Company's completion of work necessary to claim an additional $1.6 million in tax credits, which were recorded in our fiscal 2016 but related to our fiscal 2015. 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 June 30, 2017, 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, 2017, 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.
