The increase in foreign exchange losses for the three and nine months ended September 30, 2018 compared to 2017 was primarily due to a $3.6 translation loss in Argentina, as a result of changing our Argentina reporting unit's functional currency to the United States dollar as Argentina was designated as a highly-inflationary economy as of July 1, 2018.
