Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s income tax provision consists of federal, state and foreign income taxes. The tax provision for the third quarter of fiscal 2019 and 2018 was based on the estimated effective tax rates applicable for the full years ending March 31, 2019 and March 31, 2018, respectively, after giving effect to items specifically related to the interim periods. The Company’s effective income tax rate with respect to any period may be volatile based on the mix of income in the tax jurisdictions in which the Company operates, change in tax laws and the amount of the Company's consolidated income before taxes. On December 22, 2017, the Tax Act was enacted into law. Among the significant changes resulting from the law, the Tax Act reduced the U.S. federal income tax rate from 35% to 21% effective January 1, 2018, and required companies to pay a one-time transition tax on unrepatriated cumulative non-U.S. earnings of foreign subsidiaries and created new taxes on certain foreign sourced earnings. The U.S. federal statutory tax rate for fiscal 2019 is 21.0%. As of December 30, 2018, the Company had completed its accounting for the tax effects of enactment of the Tax Act. The Company recognized an income tax benefit during the quarter of $13,483, resulting from a decrease in the mandatory one-time transition tax on unremitted earnings of our foreign business. Beginning in fiscal 2019, the global intangible low-taxed income (“GILTI”), foreign derived intangible income (“FDII”), and base-erosion and anti-abuse (“BEAT”) provisions became effective. The GILTI provisions require the Company to include in its US income tax return foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary’s tangible assets. Under US GAAP, the Company is allowed to make an accounting policy choice of either (1) treating the taxes due on future US inclusions in taxable income as a current-period expense when incurred (“period cost method”) or (2) factoring amounts into a Company’s measurement of its deferred taxes (“deferred method”). As of the third quarter of fiscal 2019, the Company has elected the period cost method. Based on existing legislative guidance and interpretation, the Company has estimated that its annual effective tax rate to increase by approximately 2.8% compared to prior year effective tax rate. FDII allows a new deduction for U.S. corporations up to 37.5% of foreign derived intangible income. This is an export incentive that reduces the tax on foreign derived sales and service income. Based upon the existing legislative guidance and interpretation, the Company has estimated the impact on the annual effective tax rate to decrease by approximately 0.5% compared to prior year effective tax rate. The BEAT provisions eliminate the deductions of certain base-erosion payments to related foreign corporations and impose a minimum tax if greater than regular tax. The Company does not expect to be subject to BEAT in fiscal 2019. The consolidated effective income tax rates for the third quarter of fiscal 2019 and 2018 were (13.3)% and 141.2%, respectively, and for the nine months of fiscal 2019 and 2018 were 10.4% and 63.2%, respectively. The rate decrease in the third quarter and nine months of fiscal 2019 compared to the comparable prior year periods of fiscal 2018 is primarily due to changes in the mix of earnings among tax jurisdictions and items related to the Tax Act. Foreign income as a percentage of worldwide income is estimated to be 74% for fiscal 2019 compared to 64% for fiscal 2018. The foreign effective income tax rates for the nine months of fiscal 2019 and 2018 were 11.8% and 11.4%, respectively. The rate increase compared to the prior year period is primarily due to changes in the mix of earnings among tax jurisdictions. Income from the Company's Swiss subsidiary comprised a substantial portion of the Company's overall foreign mix of income and is taxed at an effective income tax rate of approximately 6%.
