Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes On December 22, 2017, the U.S. government enacted the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act reduces the corporate federal tax rate from 35% to 21% effective January 1, 2018 and implements a modified territorial tax system. Since the Company has a June 30th fiscal year-end, the lower tax rate resulted in a blended U.S. statutory federal rate of approximately 28% for the fiscal year ending June 30, 2018. The U.S. statutory federal rate is 21% for the year ending June 30, 2019 and subsequent fiscal years. As part of the Tax Act, U.S. companies are required to pay a one-time transition tax on the deemed repatriation of undistributed foreign earnings and remeasure deferred tax assets and liabilities. Income taxes for the quarter and six months ended December 31, 2018 have been included in the accompanying condensed consolidated financial statements using an estimated annual effective tax rate. In addition to applying the estimated annual effective tax rate to pre-tax income, the Company also includes certain items treated as discrete events to arrive at an estimated overall tax provision. During the quarter ending December 31, 2018, the Company recognized a discrete tax benefit of $0.2 million related to the completion of the accounting for the Tax Act. The Company’s effective tax rate of 25.2% for the six months ended December 31, 2018 differs from the current federal statutory rate of 21% primarily as a result of income derived from tax jurisdictions with varying income tax rates, nondeductible expenses and state income taxes. In response to the Tax Act, the Securities and Exchange Commission staff issued Staff Accounting Bulletin No. 118 (“SAB 118”) that provides guidance on accounting for the impact of the Tax Act. SAB 118 allows companies to record provisional amounts to the extent reasonably estimable and adjust them over time as more information becomes available, not to extend beyond the measurement period of one year from the enactment of the Tax Act. The Company recorded provisional amounts for the one-time transition tax on the deemed repatriation of undistributed foreign earnings and the remeasurement of deferred tax assets and liabilities during the quarter ending December 31, 2017. The Company has completed its analysis within the permitted measurement period under the guidance of SAB 118 and any adjustment to income tax expense. Included within tax expense for the December 31, 2018 reporting period is a measurement period adjustment for the one-time transition tax liability. The final impact from the enactment of the Tax Act differed from the provisional amount provided as a result of additional analysis, changes in interpretation and assumptions, as well as additional regulatory guidance that was issued. The Tax Act includes a mandatory deemed repatriation of all undistributed foreign earnings that are subject to a U.S. income tax as part of the transition. For the fiscal year ended June 30, 2018, the Company recognized provisional income tax expense of $9.6 million for a one-time transition tax liability on total post-1986 foreign subsidiaries’ earnings and profits (“E&P”) that were previously deferred from U.S. income taxes. The Company completed its analysis for this item within the permitted measurement period under the guidance of SAB 118 and determined that the provisional amount should be adjusted to the final amount of $9.4 million. As a result, a discrete tax benefit for $0.2 million was recorded during the quarter ended December 31, 2018. The Company will continue to distribute the earnings of its Canadian subsidiary, but earnings from all other geographies will continue to be considered retained indefinitely for reinvestment. It has been the practice of the Company to reinvest those earnings in the business outside the United States. Apart from the one-time transition tax, any incremental deferred income taxes on the unremitted foreign earnings are not expected to be material. As part of accounting for the Tax Act, the Company remeasured certain deferred tax assets and liabilities based on the rates at which such deferred taxes are expected to reverse in the future, which is generally 21%. For the fiscal year ended June 30, 2018, the Company recognized a provisional discrete income tax benefit of $1.6 million for the remeasurement of the Company’s net deferred tax asset and liability balances. The Company completed its analysis for this item within the permitted measurement period under the guidance of SAB 118 and determined that the provisional amount should not be adjusted. The Tax Act created a provision known as global intangible low-tax income ("GILTI") that imposes a tax on certain earnings of foreign subsidiaries. The GILTI tax became effective for the Company during fiscal year 2019 and an accounting policy election was made to treat the tax as a current period expense. The Company had approximately $1.5 million and $2.1 million of total gross unrecognized tax benefits as of December 31, 2018 and June 30, 2018, respectively. Of this total at December 31, 2018, approximately $1.2 million represents the amount of unrecognized tax benefits that are permanent in nature and, if recognized, would affect the annual effective tax rate. The Company does not believe that the total amount of unrecognized tax benefits will significantly increase or decrease within twelve months of the reporting date. The Company conducts business globally and one or more of its subsidiaries files income tax returns in the U.S. federal, various state, local and foreign jurisdictions. In the normal course of business, the Company is subject to examination by taxing authorities in countries and states in which it operates. With certain exceptions, the Company is no longer subject to federal, state and local, or non-U.S. income tax examinations by tax authorities for the years before June 30, 2013. The Company’s policy is to recognize interest and penalties related to income tax matters in income tax expense. As of December 31, 2018 and June 30, 2018, the Company had approximately $1.2 million accrued for interest and penalties, respectively. Financial results in Belgium for the quarter and six months ended December 31, 2018 produced a pre-tax income of approximately $2.7 million and $1.8 million, respectively. Belgium had pre-tax losses in the prior year. To the extent the Belgium business does not maintain profitability as expected, this could affect the valuation of certain deferred tax assets. However, in the judgment of management it is more likely than not that the deferred tax asset will be realized. Belgium enacted a corporate tax reform law on December 25, 2017 which reduces the corporate tax rate from 33% to 25% over a three-year period. The Company remeasured certain deferred tax assets and liabilities based on the rates at which such deferred taxes are expected to reverse in the future. As a result, the Company recognized income tax expense of $1.0 million as a discrete event during the year ended June 30, 2018.
