Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes On December 22, 2017 the U.S. government enacted significant tax legislation (the “Tax Act”). The Tax Act makes broad and complex changes to the U.S. tax code that will impact the Company’s financial statements, including but not limited to a permanent decrease in the corporate federal statutory income tax rate and a one-time charge from the inclusion of foreign earnings that the Company can elect to pay over eight years. The SEC staff issued Staff Accounting Bulletin 118 (“SAB 118”), which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act. In accordance with SAB 118, the Company’s measurement period was over effective in the second quarter of fiscal 2019 and Company’s accounting for the Tax Act is complete. In connection with the Company’s analysis of the impact of the Tax Act, a tax expense of approximately $21.1 million was recorded in fiscal 2018. This amount consists of an expense resulting from the re-measurement of deferred tax assets and liabilities for the corporate tax rate reduction of approximately $13.8 million and an expense related to the inclusion of foreign earnings of approximately $7.3 million. In the second quarter of fiscal 2019, the Company has recorded an additional income tax expense of approximately $1.1 million related to the inclusion of foreign earnings, bringing the total expense to $8.4 million. Effective in the second quarter of fiscal 2019, the Company has completed its accounting for the income tax effects of the Tax Act. The Company has evaluated its permanent reinvestment assertions since the Tax Act can provide opportunity to repatriate overseas cash to the U.S. at a lower tax cost. There is a dividends received deduction available for certain foreign distributions under the Tax Act, but certain foreign earnings remain subject to withholding taxes upon repatriation. As of December 30, 2018, the Company has analyzed its global working capital and cash requirements and the potential tax liabilities attributable to repatriation in regards to its permanent reinvestment assertion. During fiscal 2018, the Company removed its permanent reinvestment assertion on approximately $33 million of its foreign earnings and made distributions from its foreign earnings related to the assertion removal in the second quarter of approximately $18 million. The Company repatriated the additional $15 million of foreign earnings in the second quarter of fiscal 2019. During the second quarter of fiscal 2019, the Company has also removed its permanent reinvestment assertion on an additional approximately $21.6 million of its accumulated offshore earnings. This resulted in the previously mentioned estimated tax expense of $1.1 million. The Company has recorded the tax effects of the distributions and planned repatriations in its financial statements, including withholding taxes and currency gain and loss. For the remainder of its foreign earnings, the Company has not changed its prior assertion. Accordingly, deferred taxes attributable to its investments in its foreign subsidiaries have not yet been recorded. When calculating the income tax provision, the Company uses an estimate of the annual effective tax rate based upon information known at each interim period. The actual effective tax rate is adjusted each quarter based upon changes to the forecast as compared to the beginning of the fiscal year and each following interim period. The effective tax rate for the second quarter of fiscal 2019 was (2,682.4)%, compared to 234.2% for the same period last year. The effective tax rate for the first six months of fiscal 2019 was 26.2%, compared to (252.8)% for the same period of fiscal 2018. As a result of the Tax Act, the Company was subject to a U.S. federal statutory corporate income tax rate of 28% for the fiscal year ended July 1, 2018 and a U.S. federal statutory corporate income tax rate of 21% in the fiscal year ending June 30, 2019 and future fiscal years. The Company’s second quarter of fiscal 2019 tax rate includes the aforementioned $1.1 million discrete income tax expense related to the removal of a portion of its accumulated foreign earnings. The Company’s fiscal year 2018 tax rates reflect the estimated impact of the Tax Act at that time, including approximately $18.7 million resulting from the re-measurement of the Company’s deferred tax assets and liabilities as of the second quarter of fiscal 2018 and tax expense related to the inclusion of foreign earnings of approximately $6.2 million. The tax rates for the first six months and the second quarters of fiscal 2019 and 2018 were also impacted by the federal research and development credit.
