Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The income tax provision for the three months ended April 1, 2018 and April 2, 2017, was $2.4 million, or an effective tax rate of 30.0%, and $7.5 million, or an effective tax rate of 32.0%, respectively. The decrease in the effective tax rate for the three months ended April 1, 2018, compared to the three months ended April 2, 2017, resulted primarily from a decrease in the federal statutory rate of 35% to 21% effective as of January 1, 2018. This was offset by certain nondeductible expenses transaction costs resulting from the planned separation of the Arlo segment and the establishment of a valuation allowance for a capital loss where tax benefit is not assured. Additionally, tax expense was lower in the three months ended April 1, 2018 due to lower pre-tax earnings compared to the three months ended April 2, 2017. On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Act. The Tax Act reduced the U.S. statutory rate from 35% to 21% effective as of January 1, 2018. In addition, certain new complex tax rules related to the taxation of foreign earnings (Global Intangible Low-Taxed Income, Foreign Derived Intangible Income and Base Erosion and Anti-abuse Tax) became effective as of January 1, 2018. Based on information available to date, the Company has evaluated these provisions and estimate that there is no material impact on its income tax provision for the quarter ended April 1, 2018. In the year ended December 31, 2017, the Company recorded the effects of a reduction in tax rates from 35% to 21% on its deferred tax assets and liabilities and to record a one-time transition tax. After the enactment of the Tax Act, the SEC issued Staff Accounting Bulletin No. 118 ("SAB 118") to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Act. The Company has calculated an estimate of the impact of the Tax Act in its tax provision for the period ending December 31, 2017 in accordance with its understanding of the Tax Act and guidance available as of the date of the filing of Form 10-K and as a result recorded $48.3 million as additional income tax expense in the fourth fiscal quarter of 2017, the period in which the legislation was enacted. The provisional amount related to the remeasurement of certain deferred tax assets and liabilities, based on the rates at which they are expected to reverse in the future, was $26.6 million. The provisional amount related to the one-time transition tax on the mandatory deemed repatriation of foreign earnings was $21.7 million. The Company has reviewed these amounts based on additional guidance available and has not changed its estimates. In accordance with SAB 118, the Company has determined that the $21.7 million of current tax expense recorded in connection with the transition tax on the mandatory deemed repatriation of foreign earnings was a provisional amount and a reasonable estimate at December 31, 2017. The Company has reviewed these amounts based on additional guidance available and has not changed its estimates. The Company is subject to income taxes in the U.S. and numerous foreign jurisdictions. The future foreign tax rate could be affected by changes in the composition in earnings in countries with tax rates differing from the U.S. federal rate. The Company is under examination in various U.S. and foreign jurisdictions. The Company files income tax returns in the U.S. federal jurisdiction as well as various state, local, and foreign jurisdictions. Due to the uncertain nature of ongoing tax audits, the Company has recorded its liability for uncertain tax positions as part of its long-term liability as payments cannot be anticipated over the next twelve months. The existing tax positions of the Company continue to generate an increase in the liability for uncertain tax positions. The liability for uncertain tax positions may be reduced for liabilities that are settled with taxing authorities or on which the statute of limitations could expire without assessment from tax authorities. The possible reduction in liabilities for uncertain tax positions resulting from the expiration of statutes of limitation in multiple jurisdictions in the next twelve months is approximately $0.9 million, excluding the interest, penalties and the effect of any related deferred tax assets or liabilities.
