On June 30, 2005, Bank of America announced it would purchase credit card giant MBNA for $35 billion in cash and stock. The Federal Reserve Board gave final approval to the merger on December 15, 2005, and the merger closed on January 1, 2006. The acquisition of MBNA provided Bank of America a leading domestic and foreign credit card issuer. The combined Bank of America Card Services organization, including the former MBNA, had more than 40 million U.S. accounts and nearly $140 billion in outstanding balances. Under Bank of America, the operation was renamed FIA Card Services.
