ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Foreign Currency Exposures
We manage a portion of our exposure in foreign currency transactions through the use of foreign exchange forward contracts. Refer to Note 1(f), "Derivative Financial Instruments," to the accompanying Consolidated Financial Statements for a summary of our foreign exchange forward contracts as of December 31, 2020.
As a result of our global operations, our earnings are exposed to changes in foreign currency exchange rates. Many of our foreign businesses operate in functional currencies other than the U.S. dollar. As the U.S. dollar strengthens relative to the Euro or other foreign currencies where we have operations, there will be a negative impact on our operating results upon translation of those foreign operating results into the U.S. dollar. Foreign currency exchange rate changes positively impacted our adjusted EBITDA per credit facility, which is a non-GAAP financial measure, by approximately 0.2% in the year ended December 31, 2020. We do not hedge the translation of foreign currency operating results into the U.S. dollar.
We hedge a portion of our currency exchange exposure relating to foreign currency transactions with foreign exchange forward contracts. A sensitivity analysis indicates the potential loss in fair value on foreign exchange forward contracts outstanding at December 31, 2020, resulting from a hypothetical 10.0% adverse change in all foreign currency exchange rates against the U.S. dollar, is approximately $8.0 million. Such losses would be largely offset by gains from the revaluation or settlement of the underlying assets and liabilities that are being protected by the foreign exchange forward contracts.
Effective June 30, 2018, we determined that the economy in Argentina is highly inflationary. Beginning July 1, 2018, the U.S. Dollar is the functional currency for our subsidiaries in Argentina. Remeasurement adjustments in a highly inflationary economy and other transactional gains and losses are reflected in net earnings and were not material for the year ended December 31, 2020. These subsidiaries are included in loss from discontinued operations, net of tax, on our Consolidated Statements of Income and are not material as of December 31, 2020.

Interest Rate Risk
On December 31, 2020, we had variable-rate debt of $448.9 million. A sensitivity analysis using a one hundred basis point increase in interest rates on our variable-rate debt as of December 31, 2020, and holding other variables consistent, would cause an estimated reduction in income before income taxes of $4.5 million. We continue to evaluate the interest rate environment and look for opportunities to improve our debt structure and minimize our interest rate risk and expense.
