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 SEC 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 and nine months ended September 30, 2017, respectively, 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, 2016. During the first quarter of 2017, the Company early adopted an accounting standard update regarding the classification of pension costs. The guidance in this accounting standard update was required to be applied retrospectively, which resulted in a reclassification to the Company’s Condensed Consolidated Statement of Income for the three and nine months ended September 30, 2016, respectively. See Note 3 of Notes to Condensed Consolidated Financial Statements. 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 Statements of Income. During the first quarter of 2016, the Venezuela government announced changes to its foreign exchange controls, including eliminating the CADIVI, SICAD and SIMADI exchange rate mechanisms and replacing them with a dual exchange rate system, which consists of a protected DIPRO exchange rate, with a rate fixed at 10 BsF per U.S. dollars and, also, a floating exchange rate known as the DICOM. The DIPRO rate is only available for payment of certain imports of essential goods in the food and health sectors while the DICOM governs all other transactions not covered by the DIPRO. In light of these changes to the foreign exchange controls, during the first quarter of 2016 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. The Company did not believe it had access to the DIPRO and, therefore, believed the DICOM to be the exchange rate system available to Kelko Venezuela, which resulted in a currency conversion charge of $0.1 million in the first quarter of 2016. Due to ongoing economic and political instability in Venezuela, the DICOM BsF per U.S dollar exchange rate has continued to devalue during 2017. This resulted in the Company recording a currency conversion charge of less than $0.1 million and $0.4 million in the three and nine months ended September 30, 2017, respectively, to write down the Company’s equity investment to the current DICOM exchange rate. These currency conversion charges were recorded through equity in net income of associated companies in the Company’s Condensed Consolidated Statement of Income for each period, respectively. As of September 30, 2017, the Company’s equity investment in Kelko Venezuela was $0.1 million, valued at the current DICOM exchange rate of approximately 3,341 BsF per U.S. dollar. 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 a 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 $11.2 million and $33.0 million for the three and nine months ended September 30, 2017, respectively. Comparatively, third-party products transferred under arrangements resulting in net reporting totaled $10.7 million and $32.8 million for the three and nine months ended September 30, 2016, respectively.
