Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	Note 1 – Condensed Financial Information The condensed consolidated financial statements included herein are unaudited and have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) for interim financial reporting and the United States Securities and Exchange Commission (“SEC”) regulations. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. In the opinion of management, the financial statements reflect all adjustments (consisting only of normal recurring adjustments, except certain material adjustments, as discussed below) which are necessary for a fair statement of the financial position, results of operations and cash flows for the interim periods. The results for the three months ended March 31, 2016 are not necessarily indicative of the results to be expected for the full year. These financial statements should be read in conjunction with the Company’s Annual Report filed on Form 10-K for the year ended December 31, 2015. During the first quarter of 2016, the Company revised its Condensed Consolidated Balance Sheet for December 31, 2015, reducing non-current deferred tax assets and non-current deferred tax liabilities by $3.6 million each, to correct for offsetting deferred tax balances within related taxing jurisdictions. The Company considers such revision to be immaterial and the revision had no impact on reported equity, net income or net cash provided by operating activities. Venezuela’s economy has been considered hyper inflationary under U.S. GAAP since 2010, at which time the Company’s Venezuela equity affiliate, Kelko Quaker Chemical, S.A. (“Kelko Venezuela”), changed its functional currency from the bolivar fuerte (“BsF”) to the U.S. dollar. Accordingly, all gains and losses resulting from the remeasurement of Kelko Venezuela’s monetary assets and liabilities to published exchange rates are required to be recorded directly to the Condensed Consolidated Statement of Income. As of December 31, 2014, there were three legally available exchange rates in Venezuela, the CADIVI (or the official rate, 6.3 BsF per U.S. dollar), the SICAD I and the SICAD II. Kelko Venezuela had access to the CADIVI for imported goods, had not been invited to participate in any SICAD I auctions and had limited access to the SICAD II mechanism. Accordingly, the Company measured its equity investment and other related assets with Kelko Venezuela at the CADIVI exchange rate at December 31, 2014. During the three months ended March 31, 2015, the Venezuela government announced changes to its foreign exchange controls. There continued to be three exchange mechanisms, however, they consisted of the CADIVI, a combined SICAD I and SICAD II auction mechanism (the “SICAD”) and a newly created, marginal currency system (the “SIMADI”). In light of the first quarter of 2015 changes to Venezuela’s foreign exchange controls and the on-going economic challenges in Venezuela, the Company re-assessed Kelko Venezuela’s access to U.S. dollars, the impact on the operations of Kelko Venezuela, and the impact on the Company’s equity investment and other related assets, which resulted in revaluing its equity investment in Kelko Venezuela and other related assets to the SIMADI exchange rate of approximately 193 BsF per U.S. dollar as of March 31, 2015. This resulted in a charge of $2.8 million, or $0.21 per diluted share, recorded in the three months ended March 31, 2015. As of December 31, 2015, the Company’s equity investment in Kelko Venezuela was $0.2 million, and continued to be valued at the SIMADI exchange rate, which was approximately 198 BsF per U.S. dollar. During the three months ended March 31, 2016, the Venezuela government announced further changes to its foreign exchange controls, including eliminating the CADIVI, SICAD and SIMADI exchange rate mechanisms and replacing them with a new dual foreign exchange rate system. The Company understands that the new dual foreign exchange rate system now consists of a protected “DIPRO” exchange rate, with a rate fixed at 10 Bsf per U.S. dollar and, also, a floating supplementary market exchange rate known as the “DICOM.” The DIPRO rate will only be available for payment of certain imports of essential goods in the food and health sectors while the DICOM will govern all other transactions not covered by DIPRO. As of March 31, 2016, the published rate for the DICOM was approximately 273 BsF per U.S. dollar. In light of these changes to the foreign exchange controls during the three months ended March 31, 2016, the Company again re-assessed Kelko Venezuela’s access to U.S. dollars, the impact on the operations of Kelko Venezuela, and the impact on the Company’s equity investment and other related assets. The Company does not believe it currently has access to the DIPRO and, therefore, believes the DICOM is currently the exchange rate system available to Kelko Venezuela, which resulted in a currency conversion charge of $0.1 million, or $0.01 per diluted share, during the three months ended March 31, 2016. As of March 31, 2016, the Company’s equity investment in Kelko Venezuela was $0.2 million, valued at the DICOM exchange rate. As part of the Company’s chemical management services, certain third-party product sales to customers are managed by the Company. Where the Company acts as the principal, revenue is recognized on a gross reporting basis at the selling price negotiated with customers. Where the Company acts as an agent, such revenue is recorded using net reporting of service revenue, at the amount of the administrative fee earned by the Company for ordering the goods. Third-party products transferred under arrangements resulting in net reporting totaled $11.1 million and $11.9 million for the three months ended March 31, 2016 and 2015, respectively.
