Bank of America operated under the name BankBoston in many other Latin American countries, including Brazil. In May 2006, Bank of America and Banco Itaú (Investimentos Itaú S.A.) entered into an acquisition agreement, through which Itaú agreed to acquire BankBoston's operations in Brazil, and was granted an exclusive right to purchase Bank of America's operations in Chile and Uruguay, in exchange for Itaú shares. The deal was signed in August 2006.
