"Transaction code description is "Sale in open market or private transaction""

exchange rate financial

"Amounts presented were converted using the exchange rate of R$ 5.1853 per U.S.$1.00"

Exchange rate is the price of one currency expressed in another—for example, how many euros you receive for one US dollar. It matters to investors because changes in that price alter the reported profits, costs and value of assets for companies and portfolios that operate or hold money across borders; think of it like switching measurement units, where the same item can look bigger or smaller depending on the unit used.
