Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company has provided for potential tax liabilities due in the various jurisdictions in which the Company operates. Judgment is required in determining the worldwide income tax provision. In the ordinary course of global business, there are many transactions and calculations where the ultimate tax outcome is uncertain. Some of these uncertainties arise as a consequence of cost reimbursement arrangements among related entities. Although the Company believes its estimates are reasonable, no assurance can be given that the final tax outcome of these matters will not be different from that which is reflected in the historical income tax provisions and accruals. Such differences could have a material impact on the Company’s income tax provision and operating results in the period in which such determination is made. The Company’s effective tax rate reflects the applicable tax rate in effect in the various tax jurisdictions around the world where the Company's income is earned. The Company's effective tax rate is generally lower than the U.S. federal statutory rate, primarily due to lower statutory tax rates applicable to the Company's operations in jurisdictions in which the Company earns a portion of its income. The Tax Cuts and Jobs Act of 2017 (Tax Legislation), enacted on December 22, 2017, contains significant changes to U.S. tax law, including lowering the U.S. corporate income tax rate to 21.0%, implementing a territorial tax system, and imposing a one-time tax on deemed repatriated earnings of foreign subsidiaries. As of February 3, 2018, the Company has not completed its accounting for the tax effects of the enactment of the Tax Legislation. However, as described below the Company has made reasonable estimates of the effects on its existing deferred tax balances and the one-time transition tax. The Tax Legislation reduces the U.S. statutory tax rate from 35.0% to 21.0%, effective January 1, 2018, which results in a blended statutory income tax rate for the Company of 23.4% for fiscal 2018. For the fiscal year ending November 2, 2019 (fiscal 2019), the Company’s statutory income tax rate will be 21.0%. During the three months ended February 3, 2018, the Company recorded a $639.7 million discrete tax benefit for the remeasurement of deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally 21.0%. This provisional benefit is subject to revision based on further analysis and interpretation of the Tax Legislation and to the extent that future results differ from currently available projections. The Tax Legislation also implements a territorial tax system. As part of transitioning to the territorial tax system, the Tax Legislation includes a one-time transition tax based on our total post-1986 undistributed foreign earnings and profits that were previously deferred from U.S. income tax. During the three-month period ended February 3, 2018, the Company recorded a provisional tax expense amount for the one-time transition tax of $687.1 million, which is comprised of the $751.1 million transition tax liability less a deferred tax liability of $64.0 million recorded in prior years. This provisional estimate may be impacted by a number of additional considerations, including, but not limited to, the issuance of final tax regulations, the Company's ongoing analysis of the Tax Legislation, the Company's earnings and profits subject to the one-time transition tax, and estimated earnings and profits and foreign tax credit pools for fiscal 2018 as well as the amount of earnings and profits held in cash or other specified assets. The Company intends to elect to pay this transition tax starting in fiscal 2019 without incurring interest over a period of eight years. As a result, $60.1 million of the transition tax is classified as current taxes payable and $691.0 million is classified as non-current taxes payable. The Company recorded a $10.0 million discrete benefit for excess tax benefits from share-based payments, pursuant to ASU 2016-09, which became effective for fiscal 2018. Additionally, the Tax Legislation subjects a U.S. shareholder to tax on global intangible low-taxed income (GILTI) earned by certain foreign subsidiaries for tax years starting on or after January 1, 2018. The FASB Staff Q&A, Topic 740, No. 5, Accounting for Global Intangible Low-Taxed Income, states that an entity can make an accounting policy election to either recognize deferred taxes for temporary basis differences expected to reverse as GILTI in future years or provide for the tax expense related to GILTI in the year the tax is incurred. The Company is still evaluating the effects of the GILTI provisions and has not yet determined its accounting policy relating to deferred taxes and as such, no tax impacts are included in the Company's financial statements for the three-month period ended February 3, 2018. The Company historically asserted its intent to reinvest substantially all of its foreign earnings in foreign operations indefinitely. The Company is still in the process of analyzing the impact that the Tax Legislation has on its indefinite reinvestment assertion. Accordingly, no additional income taxes or withholding taxes have been provided for any remaining undistributed foreign earnings not subject to the transition tax, or any outside basis difference inherent in these entities. On December 22, 2017, the Securities and Exchange Commission issued guidance under Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”) directing taxpayers to consider the impact of the Tax Legislation as “provisional” when it does not have the necessary information available, prepared or analyzed (including computations) in reasonable detail to complete its accounting for the change in tax law. In accordance with SAB 118, the amount reported for the tax benefit from remeasuring the Company’s net deferred tax liabilities to the lower 21.0% statutory rate and the amount reported for the additional U.S. income tax resulting from the one-time mandatory deemed repatriation including the ongoing evaluation of the impact on the Company’s indefinite reinvestment assertions regarding undistributed earnings and profits, represents the Company's best estimate as it continues to accumulate and process data to finalize its underlying calculations and to review further guidance that regulators are expected to issue. The Company is also analyzing other provisions of the Tax Legislation to determine if they will impact the Company's effective rate for fiscal 2018 or in the future. The Company will continue to refine its adjustments through the permissible measurement period, which is not to extend beyond one year after the enactment date. Many of the provision in the Tax Legislation may have U.S. state and local income tax implications. While some states automatically adopt federal tax law changes, others may conform their laws on a specific date or may choose to decouple from the new federal tax law provisions. As such, the Company has not sufficiently analyzed the impact of the new Tax Legislation on its state and local income tax, and therefore did not record a provisional amount, but instead continues to apply Accounting Standards Codification Topic 740, Income Taxes, based on the provisions of the tax law that were in effect immediately prior to the Tax Legislation being enacted. The Company expects to complete its analysis of the effects on state and local income taxes on or before December 22, 2018 as allowed in SAB 118. All of the Company’s U.S. federal tax returns prior to fiscal year 2014 are no longer subject to examination. An IRS audit for the pre-acquisition fiscal year 2015 has been initiated for Linear. All of the Company’s Ireland tax returns prior to fiscal year 2012 are no longer subject to examination.
