This compares to 21.7% for the same period in 2024. Our financial statements are reported in USD; therefore, fluctuations in exchange rates affect the translation of foreign-denominated revenue and expenses. During the six months ended June 30, 2025 and the year ended December 31, 2024, our most significant currency exchange rate exposures were to the Chilean Peso and Euro. Gross accumulated currency translation adjustments, recorded as a separate component of shareholders’ equity, totaled $21.3 million and $52.7 million at June 30, 2025 and December 31, 2024, respectively. We are subject to foreign currency transaction risk due to fluctuations in exchange rates between the time a transaction is initiated and settled. To mitigate this risk, we use foreign currency forward contracts. These contracts fix an exchange rate, allowing us to offset potential losses (or gains) caused by exchange rate changes at the settlement date. As of June 30, 2025, we held $12.0 million in open foreign exchange forward contracts related to inventory purchases on letters of credit, compared to zero open contracts as of December 31, 2024.
