We are exposed to the impact of fluctuations in the relative value of currencies, the impact of interest rates, fluctuations in the purchase price of natural gas, ammonia and sulfur consumed in operations and changes in freight costs, as well as changes in the market value of our financial instruments. We periodically enter into derivatives in order to mitigate our foreign currency risks, interest rate risks and the effects of changing commodity prices, but not for speculative purposes. See Note 15 to the Consolidated Financial Statements in our 10-K Report and Note 12 to the Condensed Consolidated Financial Statements in this report. Foreign Currency Exchange Contracts Due to the global nature of our operations, we are exposed to currency exchange rate changes which may cause fluctuations in our earnings and cash flows. Our primary foreign currency exposures are the Canadian dollar and Brazilian real. To reduce economic risk and volatility on expected cash flows that are denominated in the Canadian dollar and Brazilian real, we use financial instruments that may include forward contracts, zero-cost collars and/or futures. Mosaic hedges cash flows on a declining basis, up to 18 months for the Canadian dollar and up to 12 months for the Brazilian real. As of June 30, 2026 and December 31, 2025, the fair value of our major foreign currency exchange contracts was $1.5 million and $1.0 million, respectively.
