Income Tax	3 Months Ended

Income Tax Disclosure [Abstract]
Income Tax	Income Tax The Company’s tax provision for interim periods is determined using an estimate of its annual effective tax rate, adjusted for discrete items, if any, that arise during the period. Each quarter, the Company updates its estimate of the annual effective tax rate, and if the estimated annual effective tax rate changes, the Company makes a cumulative adjustment in such period. The Company’s quarterly tax provision, and estimate of its annual effective tax rate, is subject to variation due to several factors, including variability in pre-tax income (or loss) and the mix of jurisdictions to which they relate, changes in how the Company does business, and tax law developments. The Company’s estimated effective tax rate for the year differs from the U.S. statutory rate primarily due to the benefit of a substantial portion of its earnings being taxed at rates lower than the U.S. statutory rate. The income tax provision for the three months ended May 5, 2018 included the current income tax expense of $3.0 million, a net increase in unrecognized tax benefits of $0.3 million, and an expense of $0.4 million related to other discrete items recorded in the quarter. The net increase in unrecognized tax benefits arose from penalties and interest of $0.5 million accrued on the outstanding unrecognized tax benefit balance, partially offset by the release of $0.2 million due to expiration of the statute of limitations in certain non-U.S. jurisdictions. The income tax provision for the three months ended April 29, 2017 included the current income tax expense of $3.5 million, a net increase in unrecognized tax benefits of $1.0 million, and an expense of $0.7 million related to other discrete items recorded in the quarter. The net increase in unrecognized tax benefits arose from penalties and interest of $0.7 million accrued on the outstanding unrecognized tax benefit balance, plus the accrual of $0.6 million for changes in prior year tax positions, partially offset by the release of $0.3 million due to expiration of the statute of limitations in certain non-U.S. jurisdictions. It is reasonably possible that the amount of unrecognized tax benefits could increase or decrease significantly due to changes in tax law in various jurisdictions, new tax audits and changes in the U.S. dollar as compared to foreign currencies within the next 12 months. Excluding these factors, uncertain tax positions may decrease by as much as $11.9 million from the lapse of statutes of limitation in various jurisdictions during the next twelve months. Government tax authorities from several non-U.S. jurisdictions are also examining the Company’s tax returns. The Company believes that it has adequately provided for any reasonably foreseeable outcomes related to its tax audits and that any settlement will not have a material effect on its results at this time. The Company operates under tax incentives in certain countries, which may be extended if certain additional requirements are satisfied. The tax incentives are conditional upon meeting certain employment and investment thresholds. The impact of these tax incentives decreased foreign taxes by $0.7 million and $0.7 million for the three months ended May 5, 2018 and April 29, 2017, respectively. The benefit of the tax incentives on net income per share was less than $0.01 per share for the three months ended May 5, 2018 and April 29, 2017. The Tax Cuts and Jobs Act ("2017 Tax Act") was signed into law on December 22, 2017. The 2017 Tax Act significantly revises the U.S. corporate income tax by, among other things, lowering the statutory corporate tax rate from 35% to 21%, eliminating certain deductions, imposing a mandatory one-time tax on accumulated earnings of foreign subsidiaries, introducing new tax regimes, and changing how foreign earnings are subject to U.S. tax. The 2017 Tax Act also enhanced and extended through 2026 the option to claim accelerated depreciation deductions on qualified property. The Company has not completed its determination of the accounting implications of the 2017 Tax Act on its tax accruals. However, the Company reasonably estimated the effects of the 2017 Tax Act and recorded provisional amounts in its financial statements as of February 3, 2018. There were no additional adjustments made to these amounts in the quarter ended May 5, 2018. As the Company continues its analysis of the 2017 Tax Act, collects and prepares necessary data, and interprets any additional guidance issued by the U.S. Treasury Department, the IRS, and other standard-setting bodies, the Company may make adjustments to the provisional amounts. Those adjustments may materially impact the Company's provision for income taxes in the period in which the adjustments are made. The Company’s principal source of liquidity as of May 5, 2018 consisted of approximately $1.9 billion of cash, cash equivalents and short-term investments, of which approximately $1.0 billion was held by foreign subsidiaries (outside Bermuda). Approximately $550 million of this amount held by foreign subsidiaries is related to subsidiaries whose earnings are undistributed and have been indefinitely reinvested outside of Bermuda. These funds are primarily held in China, Israel and the United States. The Company plans to use such amounts to fund various activities outside of Bermuda, including working capital requirements, capital expenditures for expansion, funding of future acquisitions or other financing activities. The amount of undistributed earnings of these subsidiaries for which no deferred tax liability has been provided is $430 million. If such funds were needed by the parent company in Bermuda or if the amounts were otherwise no longer considered indefinitely reinvested, the Company would incur a tax expense of approximately $160 million.
