Our financial statements are reported in USD; therefore, fluctuations in exchange rates affect the translation of foreign-denominated revenue and expenses. During the nine months ended September 30, 2024 and the year ended December 31, 2023, our most significant currency exchange rate exposures were to the Euro and the Chilean Peso.

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 September 30, 2024, we held no open foreign exchange forward contracts related to inventory purchases on letters of credit. As of December 31, 2023, we held 52 open foreign exchange forward contracts related to inventory purchases on letters of credit. These contracts matured monthly through January 2024 with a total notional value of approximately $2.9 million.
