Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The process for calculating the Company’s income tax expense involves estimating actual current taxes due plus assessing temporary differences arising from differing treatment for tax and accounting purposes that are recorded as deferred tax assets and liabilities. Deferred tax assets are periodically evaluated to determine their recoverability. The total net deferred tax asset at September 27, 2018, and December 31, 2017, was $194.5 and $72.2, respectively. The difference is primarily due to the creation of deductible temporary differences within the Transition Adjustment, and the creation of deductible temporary differences and utilization of taxable temporary differences within the current year. The Company files income tax returns in all jurisdictions in which it operates. The Company establishes reserves to provide for additional income taxes that may be due upon audit. These reserves are established based on management’s assessment as to the potential exposure attributable to permanent tax adjustments and associated interest. All tax reserves are analyzed quarterly and adjustments made as events occur that warrant modification. In general, the Company records income tax expense each quarter based on its estimate as to the full year’s effective tax rate. Certain items, however, are given discrete period treatment and the tax effects for such items are therefore reported in the quarter that an event arises. Events or items that may give rise to discrete recognition include excess tax benefits with respect to share-based compensation, finalizing amounts in income tax returns filed, finalizing audit examinations for open tax years and expiration of statutes of limitations and changes in tax law. On December 22, 2017, President Trump signed into law legislation referred to as the “Tax Cuts and Jobs Act” (the “TCJA”). The staff of the SEC has recognized the complexity of reflecting the impacts of the TCJA, and on December 22, 2017, issued guidance in Staff Accounting Bulletin 118 (“SAB 118”) which clarifies accounting for income taxes under ASC 740 if information is not yet available or complete and provides for up to a one-year period in which to complete the required analyses and accounting (the measurement period). SAB 118 describes three scenarios (or “buckets”) associated with a company’s status of accounting for income tax reform: (1) a company is complete with its accounting for certain effects of tax reform, (2) a company is able to determine a reasonable estimate for certain effects of tax reform and records that estimate as a provisional amount, or (3) a company is not able to determine a reasonable estimate and therefore continues to apply ASC 740, based on the provisions of the tax laws that were in effect immediately prior to the TCJA being enacted. The Company is substantially complete with its accounting for the one-time transition tax liability, enacted by the TCJA, during the third quarter of 2018. As a result, the Company decreased its December 31, 2017 provisional amount by $2.8, which is included as a component of income tax expense from continuing operations. To the extent that the U.S. Treasury issues additional guidance during the SAB 118 measurement period, the Company will promptly evaluate whether any additional adjustments are required. The TCJA subjects a US stockholder to tax on global intangible low-taxed income (“GILTI”) earned by certain foreign subsidiaries for years ending after December 31, 2017. 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 as a period expense. At September 27, 2018, because the Company is still evaluating the effects of the GILTI provisions, an accounting policy on whether the Company will account for GILTI as a period expense or record deferred taxes for anticipated GILTI has not been made. The Company's accounting for the effects of the GILTI provision is incomplete, however the Company has included estimated GILTI tax related to current-year operations in the Company's annualized effective tax rate and has not provided additional GILTI on deferred items. The TCJA also introduces base erosion and anti-abuse tax provisions (“BEAT”) for companies that meet certain thresholds by effectively excluding deductions on certain payments to foreign related entities. Although the Company's analysis of the tax effects of the BEAT provision is incomplete the Company does not expect to be subject to the tax. In January 2018, the FASB issued ASU 2018-02, which gives entities the option to reclassify to retained earnings the tax effects resulting from the TCJA that are stranded in accumulated other comprehensive income (“AOCI”). The new guidance may be applied retrospectively to each period in which the effect of the TCJA is recognized in the period of adoption. The Company must adopt this guidance for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption is permitted for periods for which financial statements have not yet been issued or made available for issuance, including the period the TCJA was enacted. The guidance, when adopted, will require new disclosures regarding a company’s accounting policy for releasing the tax effects in AOCI. The Company is currently evaluating how to apply the new guidance and has not determined whether it will elect to reclassify stranded amounts. The adoption of ASU 2018-02 is not expected to have a material effect on its consolidated financial statements. The 18.5% effective tax rate for the nine months ended September 27, 2018 differs from the 26.8% effective tax rate for the same period of 2017 primarily due to the enactment of the TCJA, including the reduction in the U.S. corporate federal income tax rate from 35% to 21% and the elimination of the domestic manufacturing deduction, and unrelated to the TCJA, higher state income tax credits generated in 2018 offset by the proportional tax rate effects of lower pre-tax income in 2017. The Company will continue to participate in the Internal Revenue Service’s Compliance Assurance Process (“CAP”) program for its 2018 tax year. The CAP program’s objective is to resolve issues in a timely, contemporaneous manner and eliminate the need for a lengthy post-filing examination. There are no open audits in the Company’s foreign jurisdictions. The Company expects no material change in its recorded unrecognized tax benefit liability in the next 12 months
