Income Taxes	9 Months Ended
Sep. 30, 2018
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For interim income tax reporting, we are required to estimate our annual effective tax rate and apply it to year-to-date pre-tax income/loss excluding unusual or infrequently occurring discrete items. Tax jurisdictions with losses for which tax benefits cannot be realized are excluded. For the three months ended September 30, 2018, we recorded income tax from continuing operations of $0.0 million on a loss of $2.1 million. For the three months ended September 30, 2017, we recorded income tax of $3.5 million due to an intraperiod allocation of total tax expense between continuing and discontinued operations, not applicable in 2018. The effective income tax rate for the nine months ended September 30, 2018 differs from the U.S. federal statutory rate of 21% primarily due to a valuation allowance on various deferred tax assets. Adjustments were previously made to the December 31, 2017 financial statements as a result of the Tax Reform Act passed on December 22, 2017. The elimination of the corporate alternative minimum tax and ability to file for refunds of minimum tax credit carryovers resulted in reclassification of $2.1 million as a noncurrent receivable, half of which will become a current receivable by year end 2018 to reflect the cash refund due in 2019 (with the remainder due in years 2020 through 2022). Also related to the Tax Reform Act, certain components of the Company’s deferred assets (primarily federal net operating loss carryforwards), and the associated valuation allowances, were revalued to reflect the decrease in the corporate tax rate from 35% to 21%. Analysis was performed to determine we would not be subject to the Deemed Repatriation Transition Tax on foreign subsidiary historical earnings. Another tax reform change related to our foreign subsidiaries is the minimum tax on global intangible low-taxed income (“GILTI”) effective January 1, 2018. Our preliminary assessment is that the GILTI calculation will have no material effect on the company’s tax rate, as will be confirmed with a detailed analysis at year end. No further adjustments relating to tax reform were required for the three months ended September 30, 2018. We file income tax returns in multiple jurisdictions and are subject to review by various U.S and foreign taxing authorities. Our U.S. federal income tax returns for 2014 through 2017 are subject to examination by the Internal Revenue Service. With few exceptions, we are no longer subject to examination by foreign tax jurisdictions or state and local tax jurisdictions for years before 2011. In the event that we have determined not to file tax returns with a particular state or city, all years remain subject to examination by the tax jurisdiction. We accrue for the effects of uncertain tax positions and the related potential penalties and interest. Our liability related to uncertain tax positions, which is presented in other liabilities on our Condensed Consolidated Balance Sheets and which includes interest and penalties and excludes certain unrecognized tax benefits that have been netted against deferred tax assets, was $0.7 million and $0.9 million as of September 30, 2018 and December 31, 2017, respectively. These liabilities are associated with our Legacy Businesses and have been included with the separately presented other liabilities of discontinued operations on the face of our Condensed Consolidated Balance Sheet. It is reasonably possible that the amount of the unrecognized tax benefit with respect to certain of our unrecognized tax positions will increase or decrease during the next 12 months; however, it is not possible to reasonably estimate the effect at this time.
