Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For each interim reporting period, the Company makes an estimate of the effective tax rate it expects to be applicable for the full fiscal year for its operations. This estimated effective rate is used in providing for income taxes on a year-to-date basis. The Company’s effective tax rate through the first six months of fiscal 2020 was (8)%, compared with 16% for the same period of fiscal 2019. The decrease in the effective rate was primarily attributable to changes in jurisdictional mix of income in fiscal 2020 compared with the same period of fiscal 2019 and discrete tax benefits through the second quarter of fiscal 2019 applied against a year-to-date loss. The effective tax rate differs from the U.S. federal statutory rate due primarily to the valuation allowance against the Company’s U.S. deferred tax assets and income in foreign jurisdictions that are taxed at different rates than the U.S. statutory tax rate. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was enacted and signed into law. The CARES Act includes provisions relating to refundable payroll tax credits, deferral of certain payment requirements for the employer portion of Social Security taxes, net operating loss carryback periods and temporarily increasing the amount of net operating losses that corporations can use to offset income, alternative minimum tax ("AMT") credit refunds, modifications to the net interest deduction limitations, and technical corrections to tax depreciation methods for qualified improvement property. The CARES Act did not materially affect the Company’s second quarter of fiscal 2020 income tax provision, deferred tax assets and liabilities, or related taxes payable. The Company continues to assess the future implications of these provisions within the CARES Act on its consolidated condensed financial statements but does not expect the impact to be material. The Company is subject to income taxes in the U.S. federal jurisdiction, Ireland, Italy, and various state and local jurisdictions. The Company believes it has appropriate support for its federal income tax returns.
