UniCredit Bank Austria AG, branded and widely referred to as Bank Austria, is an Austrian bank, 99,9965% owned by Milan-based pan-European banking group UniCredit. Bank Austria was formed in 1991 by merger of Länderbank and Vienna's Zentralsparkasse, acquired Creditanstalt-Bankverein in 1997, and merged with it to form Bank Austria-Creditanstalt (BA-CA) in 2002. Its name reverted to Bank Austria in 2008, as UniCredit, the bank's owner since 2005, phased out the history-laden Creditanstalt brand.
