Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	Note 10 – Income Taxes and Uncertain Income Tax Positions The Company’s effective tax rate for the three months ended March 31, 2018 was 29.8% compared to 50.8% for the three months ended March 31, 2017. The Company’s elevated effective tax rate in the first quarter of 2017 was primarily due to certain non-deductible costs related to the pending Houghton Combination. The Company’s effective tax rate in the first quarter of 2018 also included the impact of certain non-deductible combination-related expenses, but to a lesser extent. In addition, the Company’s effective tax for the three months ended March 31, 2018 benefited from the decrease in the U.S. statutory tax rate from 35% in the prior year to 21% in the current quarter as a result of the Tax Cuts and Jobs Act (“U.S. Tax Reform”), partially offset by a negative impact from changes in uncertain tax positions quarter-over-quarter. As previously disclosed in its Annual Report filed on Form 10-K for the year ended December 31, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as U.S. Tax Reform on December 22, 2017. U.S. Tax Reform includes multiple changes to the U.S. tax code with varying effects on the Company’s results for the three months ended March 31, 2018. The SEC staff issued guidance on accounting for the tax effects of U.S. Tax Reform and provided a one-year measurement period for companies to complete the accounting. Companies are required to reflect the income tax effects of those aspects of U.S. Tax Reform for which the accounting is complete. To the extent that a company’s accounting for certain income tax effects of U.S. Tax Reform are incomplete but the company is able to determine a reasonable estimate, it must record a provisional estimate in its financial statements. The Company has made reasonable interpretations and assumptions with regard to various uncertainties and ambiguities in the application of certain provisions of U.S. Tax Reform. It is possible that the Internal Revenue Service (“IRS”) could issue subsequent guidance or take positions on audit that differ from the Company’s interpretations and assumptions. The Company currently believes subsequent guidance issued or interpretations made by the IRS will not be materially different from the Company’s application of the provisions of U.S. Tax Reform. The Company is continuing to evaluate all of the provisions of U.S. Tax Reform and expects to finalize its assessment during the one-year measurement period provided for by the SEC to complete the accounting for U.S. Tax Reform. During the three months ended March 31, 2018, the Company has not made any significant changes to its initial assessments made during the fourth quarter of 2017. As of March 31, 2018, the Company’s cumulative liability for gross unrecognized tax benefits was $7.8 million. As of December 31, 2017, the Company’s cumulative liability for gross unrecognized tax benefits was $6.8 million. The Company continues to recognize interest and penalties associated with uncertain tax positions as a component of taxes on income before equity in net income of associated companies in its Condensed Consolidated Statements of Income. The Company recognized an expense of $0.1 million for interest and an expense of $0.1 million for penalties in its Condensed Consolidated Statement of Income for the three months ended March 31, 2018, and recognized a credit of $0.2 million for interest and an expense of less than $0.1 million for penalties in its Condensed Consolidated Statement of Income for the three months ended March 31, 2017. As of March 31, 2018, the Company had accrued $0.7 million for cumulative interest and $1.2 million for cumulative penalties in its Condensed Consolidated Balance Sheets, compared to $0.6 million for cumulative interest and $1.0 million for cumulative penalties accrued at December 31, 2017. During the three months ended March 31, 2018 and 2017, the Company recognized a decrease of less than $0.1 million and $0.4 million, respectively, in its cumulative liability for gross unrecognized tax benefits due to the expiration of the applicable statutes of limitations for certain tax years. The Company estimates that during the year ending December 31, 2018 it will reduce its cumulative liability for gross unrecognized tax benefits by approximately $1.0 to $1.1 million due to the expiration of the statute of limitations with regard to certain tax positions. This estimated reduction in the cumulative liability for unrecognized tax benefits does not consider any increase in liability for unrecognized tax benefits with regard to existing tax positions or any increase in cumulative liability for unrecognized tax benefits with regard to new tax positions for the year ending December 31, 2018. The Company and its subsidiaries are subject to U.S. Federal income tax, as well as the income tax of various state and foreign tax jurisdictions. Tax years that remain subject to examination by major tax jurisdictions include Brazil from 2000, Italy from 2007, the Netherlands and the United Kingdom from 2012, Spain, China and Mexico from 2013, India from its fiscal year beginning April 1, 2013 and ending March 31, 2014, the United States from 2014, and various domestic state tax jurisdictions from 2008. As previously reported, the Italian tax authorities have assessed additional tax due from the Company’s subsidiary, Quaker Italia S.r.l., relating to the tax years 2007 through 2013. The Company has filed for competent authority relief from these assessments under the Mutual Agreement Procedures of the Organization for Economic Co-Operation and Development for all years except 2007. As of March 31, 2018, the Company believes it has adequate reserves, where merited, for uncertain tax positions with respect to these and all other audits.
