Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes On December 22, 2017, the Tax Cuts and Jobs Act (“the Act”) was signed into law. The Act reduces the corporate tax rate from 35% to 21%. During the three months ending December 31, 2017, the Company revised its estimated annual effective tax rate to reflect this change in the statutory rate. The rate change is administratively effective at the beginning of the Company's 2018 fiscal year, using a blended rate of 24.53%. At December 31, 2017, the Company had not yet completed its accounting for the tax effects of enactment of the Act; however, in certain cases the Company has made a reasonable estimate of the Act's effects. The Company recognized a tax benefit of $3.5 million for the period ended December 31, 2017 as a result of adjusting its deferred tax balance to reflect the new corporate tax rate. In addition, the Act makes the alternative minimum tax (“AMT”) credit refundable in tax years beginning after 2017 and before 2022. As a result of this change, the Company reduced its valuation allowance on its AMT credits and recognized an income tax benefit of $1.7 million. The effect of the international provisions of the Act, which establish a territorial tax system and subjects certain foreign earnings on which US tax is currently deferred to a one-time transition tax, is uncertain. Based on a preliminary analysis, the Company has not recorded any provisional amounts in its financial statements for the three months ending December 31, 2017. The Company’s interim effective income tax rate is based on management’s best current estimate of the Company's expected annual effective income tax rate. The Company recorded a pre-tax loss in the first quarter of fiscal year 2018 and its corresponding effective tax rate is approximately -5.8% before recognition of a $5.2 million tax benefit for the adjustment to its deferred tax balance and reduction to its valuation allowance on AMT credits resulting from changes to the tax law. The Company applies the authoritative guidance related to uncertainty in income taxes. ASC 740 states that a benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, on the basis of technical merits. The Company records unrecognized tax benefits as a reduction to its deferred tax asset for its net operating loss carryforward. The Company identified no new uncertain tax positions during the three months ended December 31, 2017. The Company’s policy is to recognize interest and penalties in the period in which they occur in the income tax provision. The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction, various state and local jurisdictions and in foreign jurisdictions, primarily Canada and the U.K. Currently, the Company has open federal and state income tax examinations for fiscal years 2012 through 2015. The Company anticipates no material tax liability will arise from these examinations. The statute of limitations for U.S. federal income tax returns for years prior to fiscal 2013 is now closed. However, certain tax attribute carryforwards that were generated prior to fiscal 2013 may be adjusted upon examination by tax authorities if they are utilized.
