Income Taxes	9 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes During the quarter ended December 31, 2018, the Company recognized $2.6 million of income tax expense, comprised of $2.9 million of income tax expense related to foreign operations, $0.2 million of federal income tax benefit, and $0.1 million of state income tax benefit. During the nine months ended December 31, 2018, the Company recognized $9.2 million of income tax expense, comprised of $9.6 million of income tax expense related to foreign operations and $0.4 million of state income tax benefit. The $9.6 million of income tax expense related to foreign operations includes a $0.6 million benefit related to the settlement of uncertain tax positions. During the quarter ended December 31, 2017, the Company recognized $2.0 million of income tax expense comprised of $2.7 million of income tax expense related to foreign operations and $0.7 million of federal income tax benefit. During the nine months ended December 31, 2017, the Company recognized $6.0 million of income tax expense, comprised of $6.4 million of income tax expense related to foreign operations, $0.5 million of federal income tax benefit, and $0.1 million of state income tax expense. The effective tax rates differ from income taxes recorded using a statutory rate largely due to the relative mix in earnings and losses in various tax jurisdictions and the usage of the net operating losses and reversal of associated valuation allowances previously recorded on the deferred tax assets. Tax Cuts and Jobs Act The Tax Cuts and Jobs Act (the “Act”) was enacted on December 22, 2017. The Act reduced the US federal corporate tax rate from 35% to 21%, required companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred, and created new taxes on certain foreign-sourced earnings. During the 2018 fiscal year and in the first six months of fiscal year 2019, the Company recorded provisional amounts for certain enactment-date effects of the Act by applying the guidance in SAB 118, because the Company had not yet completed its accounting for all of the tax effects of the Act. Certain provisions of the Act did not impact the Company until the current fiscal year. These provisions include, but are not limited to, the base erosion anti-abuse tax (“BEAT”), the provision designed to tax global intangible low-taxed income (“GILTI”), the foreign-derived intangible income (“FDII”) provision, and the provision designed to limit interest expense deductions. During the quarter ended December 31, 2018, the Company completed its accounting for the enactment-date income tax effects of the Act as the remeasurement period per SAB 118 ended on December 22, 2018. The Company has completed the analysis based on legislative updates relating to the Act currently available. These tax effects related to the one-time transition tax and the reduced corporate tax rate. The Company recognized the below adjustments as a component of income tax expense. One-time Transition Tax The one-time transition tax is based on the Company’s total post-1986 earnings and profits which were previously deferred from U.S. income taxes under U.S. law. In previous periods, the Company recorded provisional amounts for its one-time transition tax liability for each of its foreign subsidiaries, and the amounts were offset by utilizing net operating losses that had been carried forward from prior years. Upon further analysis of the Act and notices and regulations issued and proposed under Internal Revenue Code (“IRC”) Section 965 by the U.S. Department of Treasury and the Internal Revenue Service, the Company finalized its calculations of the transition tax liability during the current reporting period. The final net taxable income the Company reported on its 2018 federal income tax return under IRC Section 965, after allowable deductions under IRC Section 965(c), was $34.3 million. The amount was included as a component of income tax expense and offset by federal net operating loss carryover utilizations, resulting in a net income tax expense of zero. There is no impact to foreign locations. Deferred tax assets and liabilities The Company had initially determined a $0.8 million tax benefit related to the US federal corporate tax rate change to its existing deferred tax balances, which was included as a component of income tax expense for fiscal year 2018. Upon further analysis of certain aspects of the Act and refinement of our calculations, the $0.8 million tax benefit remains unchanged. Global intangible low-taxed income (“GILTI”) The Act subjects a U.S. shareholder to tax on GILTI earned by certain foreign subsidiaries. The Financial Accounting Standards Board (“FASB”) Staff Q&A, Topic 740, No. 5, Accounting for Global Intangible Low-Taxed income, states that an entity can make an accounting policy election to either recognize deferred taxes for temporary basis differences expected to reverse as GILTI in future years, or to provide for the tax expense related to GILTI in the year the tax is incurred as a period expense. The Company has elected to account for GILTI as a period cost in the year the tax is incurred. At December 31, 2018, the Company has sufficient U.S. net operating loss carryovers to offset the additional taxable income related to the GILTI inclusion during the nine months ended December 31, 2018, resulting in a net income tax expense of zero. Foreign-Derived Intangible Income (“FDII”) The Act provides tax incentives to U.S. companies to earn income from the sale, lease, or license of goods and services abroad in the form of a deduction for foreign-derived intangible income. The tax law limits the amount of the FDII deductions to the U.S. shareholder’s taxable income. At December 31, 2018, the Company estimates to utilize net operating loss carryovers to absorb its taxable income for the fiscal year 2019. As a result, the Company is not estimating any taxable income deduction related to FDII. Base Erosion Anti-Abuse Tax (“BEAT”) Under the Act, an entity must pay a BEAT tax, if the BEAT is greater than its regular tax liability. The BEAT calculation eliminates the deduction of certain payments made to foreign affiliates, referred to as base erosion payments, but applies a lower tax rate on the resulting BEAT income. During the nine months ended December 31, 2018, the Company estimates a tax expense of $0.8 million related to BEAT. The annual BEAT inclusion increased the Company’s annual effective tax rate by 0.7% for the 2019 fiscal year. Interest Expense Deduction Limits The Act limits the deduction for net interest expense incurred by U.S. corporations for amounts that exceed 30% of the corporation’s adjusted taxable income for the year. The adjusted taxable income is computed initially excluding depreciation, amortization, or depletion and includes these items beginning in the year 2022. The Act permits an indefinite carryforward of any disallowed business interest expense. At December 31, 2018, the Company estimates that its net interest expense deduction for the fiscal year 2019 will not be limited. Valuation Allowance of U.S. Group Companies At December 31, 2018, the Company has a valuation allowance against the net deferred tax assets of its U.S. group entities. The Company intends to continue maintaining a full valuation allowance on these deferred tax assets until there is sufficient evidence to support the reversal of all or some portion of these allowances. However, given its current earnings and anticipated future earnings, the Company believes that there is a reasonable possibility that the U.S. valuation allowance could be released within the next 12 months, as sufficient positive evidence may become available to allow it to reach a conclusion that a significant portion of the valuation allowance will no longer be needed. Release of the valuation allowance would result in the recognition of certain deferred tax assets and a decrease to income tax expense for the period in which the release is recorded. However, the exact timing and amount of the valuation allowance release is subject to change on the basis of the level of profitability that that Company is actually able to achieve.
