Dec. 31, 2017
Income Tax Disclosure [Abstract]
Income Taxes	13. Income Taxes The Company’s effective tax rate for the three months ended December 31, 2017 was impacted by the Tax Cuts and Jobs Act (“the Act”), which was enacted into law on December 22, 2017. Income tax effects resulting from changes in tax laws are accounted for by the Company in accordance with the authoritative guidance, which requires that these tax effects be recognized in the period in which the law is enacted and the effects are recorded as a component of provision for income taxes from continuing operations. As a result, the Company made changes to its provision for income tax resulting from the enactment of the Act for the three months ended December 31, 2017. The Act includes significant changes to the U.S. corporate income tax system which reduces the U.S. federal corporate tax rate from 35.0% to 21.0% as of January 1, 2018; shifts to a modified territorial tax regime which requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred; and creates new taxes on certain foreign-sourced earnings. The decrease in the U.S. federal corporate tax rate from 35.0% to 21.0% results in a blended statutory tax rate of 24.5% for the Company’s fiscal year ending September 30, 2018. The new taxes for certain foreign-sourced earnings under the Act are effective for the Company after the fiscal year ending September 30, 2018. The Company is currently in the early stages of evaluating the impact of the Act on its consolidated financial statements. Based on the Company’s initial assessments to date, it expects the one-time transition tax on certain foreign earnings and profits to have a minimal cash impact since it anticipates that it will be able to utilize existing net operating loss carryforwards to substantially offset any taxes payable on foreign earnings and profits. Additionally, the Company has adjusted its U.S. gross deferred tax assets and liabilities to the new 21% statutory tax rate; however, it also recorded a corresponding adjustment to a valuation allowance which resulted in no net impact to deferred tax assets or provision for income taxes. Except for the adjustments referred to above, the Company has not recorded any income tax effects of the Act in its consolidated financial statements (including any provisional amounts) because it does not yet have the necessary information available, prepared or analyzed in reasonable detail to complete the applicable accounting. The Company’s effective tax rates for the three months ended December 31, 2017 and 2016 were (0.1)% and (9.6)% , respectively. The United States statutory rate for the three months ended December 31, 2017 and 2016 was 24.5% (blended) and 35%, respectively. Compared to the United States statutory rate, the lower effective tax rates resulted primarily from the provision of a valuation allowance against the Company’s U.S. and Canadian deferred tax assets due to the uncertainty surrounding the Company’s ability to utilize such deferred tax assets in the future to offset taxable income.
