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 $4.5 million and $7.1 million for the three and six months ended March 31, 2017, respectively, compared to an income tax benefit of $3.9 million and $3.3 million for the three and six months ended March 31, 2016, respectively. Our current fiscal year income tax benefit was primarily driven by (1) the loss in earnings 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. The tax benefit for the six months ended March 31, 2016 was primarily driven by (1) our loss in earnings from continuing operations; and (2) the Company's completion of work necessary to claim $1.4 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 March 31, 2017, we concluded that it is more likely than not that a substantial portion of our deferred tax assets will be realized. As of March 31, 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.
