Nordea Bank Abp, formerly Nordea Bank Abp roots go back 200 years, with nearly 300 banks founded in Nordic countries from 1820 onwards. Nordea is the largest Swedish bank by asset size and by customer base served, both in the Nordics and the Baltic region. As of Jan. 2, 2017, its subsidiaries in Sweden, Finland, Denmark, and Norway were converted into bank branches of the Swedish parent company to achieve a simpler legal and operational structure. In August 2016, Nordea and DNB merged their operations in Estonia, Latvia, and Lithuania to create a leading bank in the region. In 2017, Nordea decided to move its official headquarters to Finland.
