Hyper-inflationary economies Economies that have a cumulative three-year rate of inflation exceeding 100% are considered hyper-inflationary under U.S. GAAP. A legal entity that operates within an economy deemed to be hyper-inflationary is required to remeasure its monetary assets and liabilities to the applicable published exchange rates and record the associated gains or losses resulting from the remeasurement directly to the Condensed Consolidated Statements of Operations. The Company has a 50-50 joint venture in a Venezuelan affiliate, Kelko Quaker Chemical, S.A. Venezuela’s economy has been considered hyper-inflationary under U.S. GAAP since 2010. During the three and nine months ended September 30, 2018, the Company recorded remeasurement losses of less than $0.1 million and $0.3 million, respectively, associated with the applicable currency conversions related to Venezuela. These losses were recorded within equity in net income of associated companies in the Company’s Condensed Consolidated Statements of Operations. Due to heightened foreign exchange controls and restrictions currently present within Venezuela, during the third quarter of 2018 the Company concluded that it no longer had significant influence over this affiliate. Prior to this determination, the Company historically accounted for this affiliate under the equity method. As of September 30, 2019 and December 31, 2018, the Company has no remaining carrying value for its investment in Kelko Venezuela. Based on various indices or index compilations currently being used to monitor inflation in Argentina as well as recent economic instability, effective July 1, 2018, Argentina’s economy was considered hyper-inflationary under U.S. GAAP. As a result, the Company began applying hyper-inflationary accounting with respect to the Company's wholly owned Argentine subsidiary beginning July 1, 2018. In addition, Houghton has an Argentine subsidiary to which hyper-inflationary accounting also is applied. As of, and for the nine months ended September 30, 2019, the Company's Argentine subsidiaries represented less than 1% of the Company’s consolidated total assets and net sales, respectively. During the three and nine months ended September 30, 2019, the Company recorded $0.7 million and $0.9 million, respectively, of remeasurement losses associated with the applicable currency conversions related to Argentina. Comparatively, during each of the three and nine months ended September 30, 2018, the Company recorded approximately $0.5 million of remeasurement losses associated with the applicable currency conversion related to Argentina. These losses were recorded within foreign exchange gains (losses), net, which is a component of other income (expense), net, in the Company’s Condensed Consolidated Statements of Operations.
