It was formed on October 1, 2005 by the merger of the separate banks PSK and BAWAG. As of 2016, the bank serviced more than 2.5 million customers all over Austria. It serves Austrian retail, small business and corporate customers across the country, offering savings, payment, lending, leasing, investment, building society and insurance products and services. Two-thirds of the customer loans derive from Austria. The international activities focus on retail, corporate, commercial real estate and portfolio lending in Western developed countries.
