Argentina Blue Chip Swap Transaction
The Central Bank of Argentina maintains currency controls that limit our ability to access U.S. dollars in Argentina and remit cash from our Argentine operations. There is a foreign exchange mechanism known as Blue Chip Swaps, which effectively results in a parallel U.S. dollar exchange rate. During the three and six months ended June 30, 2024, we entered into Blue Chip Swap transactions in order to remit cash from our Argentine operations that resulted in pre-tax loss on investment of $1 million and $3 million, respectively.
