Cariplo SpA was formed in 1991 when Cassa di Risparmio delle Provincie Lombarde (sold by Ente Cassa di Risparmio delle Provincie Lombarde ) merged with its subsidiary IBI. Banco Ambrosiano Veneto originated with Nuovo Banco Ambrosiano and Banca Cattolica del Veneto which merged in 1989. The bank increased in size during the 1990s due to numerous acquisitions (Citibank Italia, Banca Vallone di Galatina and European securities dealer Caboto among others).[citation needed]
