Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes U.S. Tax Reform On December 22, 2017, President Trump signed into law new tax legislation commonly referred to as the Tax Cuts and Jobs Act (the "TCJA"), which became effective January 1, 2018. The TCJA significantly revises U.S. tax law by, among other provisions, lowering the U.S. federal statutory income tax rate from 35% to 21%, creating a territorial tax system that includes a mandatory one-time transition tax on previously deferred foreign earnings, and eliminating or reducing certain income tax deductions. ASC Topic 740, "Income Taxes," requires the effects of changes in tax laws to be recognized in the period in which the legislation is enacted. However, due to the complexity and significance of the TCJA's provisions, the SEC staff issued Staff Accounting Bulletin No. 118 ("SAB 118") on December 22, 2017, which allows companies to record the tax effects of the TCJA on a provisional basis based on a reasonable estimate, and then, if necessary, subsequently adjust such amounts during a limited measurement period as more information becomes available. The measurement period ends when a company has obtained, prepared, and analyzed the information necessary to finalize its accounting, but cannot extend beyond one year from enactment. During the third quarter of Fiscal 2018, the Company recorded one-time charges of $231.3 million within its income tax provision in connection with the TCJA, of which $215.5 million related to the mandatory transition tax, which it expects to pay over an eight-year period (see Note 13). The remaining charge of $15.8 million related to the revaluation of the Company's deferred tax assets and liabilities. Collectively, these one-time charges, which were recorded on a provisional basis, negatively impacted the Company's effective tax rate by 12,410 basis points and 4,980 basis points during the three-month and nine-month periods ended December 30, 2017, respectively, and lowered its diluted earnings per share by $2.80 during each of these periods. The provisional amounts were based on the Company's present interpretations of the TCJA and current available information, including assumptions and expectations about future events, such as its projected financial performance, and are subject to further refinement as additional information becomes available (including the Company's actual full Fiscal 2018 results of operations and financial condition, as well as potential new or interpretative guidance issued by the FASB or the Internal Revenue Service and other tax agencies) and further analyses are completed. Effective Tax Rate The Company's effective tax rate, which is calculated by dividing each fiscal period's income tax provision by pretax income, was 143.9% and 73.8% during the three-month and nine-month periods ended December 30, 2017, respectively, and 34.0% and 36.0% during the three-month and nine-month periods ended December 31, 2016, respectively. The effective tax rates for the three-month and nine-month periods ended December 30, 2017 were higher than the U.S. federal statutory income tax rate of 35% primarily as a result of the one-time charges recorded in connection with the TCJA, as previously discussed, partially offset by the favorable impact of the proportion of earnings generated in lower taxed foreign jurisdictions versus the U.S. and foreign income tax reserve releases. Additionally, the effective tax rate for the nine months ended December 30, 2017 reflected the negative impact of the adoption of ASU 2016-09 (see Note 4), as well as the unfavorable impact of additional income tax reserves associated with certain income tax audits. The effective tax rates for the three-month and nine-month periods ended December 31, 2016 reflected the favorable impact of the proportion of earnings generated in lower taxed foreign jurisdictions versus the U.S., partially offset by valuation allowances and adjustments recorded on deferred tax assets, certain nondeductible expenses, and unrecognized tax benefits recorded on current year tax positions. The effective tax rate for the nine months ended December 31, 2016 was also unfavorably impacted by additional tax reserves associated with an income tax settlement and certain income tax audits. Uncertain Income Tax Benefits The Company classifies interest and penalties related to unrecognized tax benefits as part of its income tax provision. The total amount of unrecognized tax benefits, including interest and penalties, was $76.4 million and $62.7 million as of December 30, 2017 and April 1, 2017, respectively, and is included within non-current liability for unrecognized tax benefits in the consolidated balance sheets. The net addition of $13.7 million in unrecognized tax benefits, including interest and penalties, primarily related to additional unrecognized tax benefits recorded. The total amount of unrecognized tax benefits that, if recognized, would affect the Company's effective tax rate was $60.5 million and $46.7 million as of December 30, 2017 and April 1, 2017, respectively. Future Changes in Unrecognized Tax Benefits The total amount of unrecognized tax benefits relating to the Company's tax positions is subject to change based on future events including, but not limited to, settlements of ongoing tax audits and assessments and the expiration of applicable statutes of limitations. Although the outcomes and timing of such events are highly uncertain, the Company does not anticipate that the balance of gross unrecognized tax benefits, excluding interest and penalties, will change significantly during the next twelve months. However, changes in the occurrence, expected outcomes, and timing of such events could cause the Company's current estimate to change materially in the future. The Company files a consolidated U.S. federal income tax return, as well as tax returns in various state, local, and foreign jurisdictions. The Company is generally no longer subject to income tax examinations for years prior to its fiscal year ended April 3, 2010.
