Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three and nine months ended September 30, 2020, our income tax benefit was positively impacted by the settlement of the 2006 through 2016 U.S. Federal income tax audit, partially offset by losses in certain foreign jurisdictions where we received no tax benefit due to 100% valuation allowances, by net losses on sales of businesses and the classification of certain assets as held for sale for which we received minimal tax benefit and by tax expense associated with the change to our assertion regarding the permanent reinvestment of undistributed earnings attributable to certain foreign subsidiaries. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was enacted and signed into law. The CARES Act includes several provisions for corporations including increasing the amount of deductible interest, allowing companies to carryback certain net operating losses (“NOLs”) and increasing the amount of NOLs that corporations can use to offset income. The CARES Act did not materially affect our quarter or year-to-date income tax provision, deferred tax assets and liabilities, or related taxes payable, nor do we expect it to have a material impact for the full year. In 2020, in response to changes in non-US tax law, a decision was made to change our indefinite reinvestment assertion on a $120.0 of undistributed foreign earnings of specific subsidiaries. We recorded $10.4 of income tax costs associated with this change to our assertion. In the third quarter of 2020, in response to restructuring actions taken within foreign subsidiaries, a decision was made to change our indefinite reinvestment assertion on a $46.0 of undistributed foreign earnings of specific subsidiaries. We recorded $3.2 of income tax costs associated with this change to our assertion. We have various tax years under examination by tax authorities in various countries, and in various states, in which we have significant business operations. It is not yet known whether these examinations will, in the aggregate, result in our paying additional taxes. We believe our tax reserves are adequate in relation to the potential for additional assessments in each of the jurisdictions in which we are subject to taxation. We regularly assess the likelihood of additional tax assessments in those jurisdictions and, if necessary, adjust our reserves as additional information or events require. On July 29, 2020, the Internal Revenue Service notified the Company that the U.S. Federal income tax audit of years 2006 through 2016 has been finalized and settled. As a result, we recognized an income tax benefit of $136.2 in the third quarter of 2020. With respect to all tax years open to examination by U.S. federal, various state and local, and non-U.S. tax authorities, we currently anticipate that total unrecognized tax benefits will decrease by an amount between $10.0 and $20.0 in the next twelve months, a portion of which will affect our effective income tax rate, primarily as a result of the settlement of tax examinations and the lapsing of statutes of limitations. We are effectively settled with respect to U.S. federal income tax audits through 2016. With limited exceptions, we are no longer subject to state and local income tax audits for years prior to 2013 or non-U.S. income tax audits for years prior to 2009.
