Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Effective Tax Rate The Company's effective tax rate, which is calculated by dividing each fiscal period's income tax benefit (provision) by pretax income (loss), was (34.4%) and 17.3% during the three-month and six-month periods ended September 26, 2020, respectively, and 23.1% and 21.9% during the three-month and six-month periods ended September 28, 2019, respectively. The effective tax rates for the three-month and six-month periods ended September 26, 2020 were lower than the U.S. federal statutory income tax rate of 21% primarily due to valuation allowances recorded against certain deferred tax assets as a result of significant business disruptions attributable to COVID-19 that could impact the ultimate realizability of such assets, as well as tax impacts on stock based compensation and other permanent adjustments, partially offset by expected net operating loss carrybacks allowed under the CARES Act (as defined below). The effective tax rates for the three-month and six-month periods ended September 28, 2019 were slightly higher than the U.S. federal statutory income tax rate of 21% primarily due to additional income tax reserves largely associated with certain income tax audits. In response to the COVID-19 pandemic, various governments worldwide have enacted, or are in the process of enacting, measures to provide aid and economic relief to companies adversely impacted by the pandemic. For example, on March 27, 2020, the U.S. government enacted the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act"). The CARES Act includes various provisions, including the modification of net operating loss carryback periods and limitation, modification to interest deduction limitations, and creation of refundable employee retention tax credits, among other provisions. Certain of these provisions will favorably impact the Company's Fiscal 2021 operating results. Swiss Tax Reform In May 2019, a public referendum was held in Switzerland that approved the Federal Act on Tax Reform and AHV Financing (the "Swiss Tax Act"), which became effective January 1, 2020. The Swiss Tax Act eliminates certain preferential tax items at both the federal and cantonal levels for multinational companies, and provides the cantons with parameters for establishing local tax rates and regulations. The Swiss Tax Act also provides transitional provisions, one of which allows eligible companies to increase the tax basis of certain assets based on the value generated by their business in previous years, and amortize such adjustment as a tax deduction over a transitional period. During the second quarter of Fiscal 2020, the Swiss Tax Act was enacted into law, resulting in an immaterial adjustment associated with the revaluation of the Company's Swiss deferred tax assets and liabilities and the then estimated annual effective tax rate. Uncertain Income Tax Benefits The Company classifies interest and penalties related to unrecognized tax benefits as part of its income tax benefit (provision). The total amount of unrecognized tax benefits, including interest and penalties, was $87.6 million and $88.9 million as of September 26, 2020 and March 28, 2020, respectively, and is included within non-current liability for unrecognized tax benefits in the consolidated balance sheets. The total amount of unrecognized tax benefits that, if recognized, would affect the Company's effective tax rate was $66.2 million and $71.7 million as of September 26, 2020 and March 28, 2020, 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 examinations by the relevant tax authorities for years prior to its fiscal year ended March 30, 2013.
