The practical effect of this was that from 1 April 2007 National Irish Bank was no longer regulated by the Central Bank of Ireland but by the Danish Financial Services Authority, as NIB was now to be a division of Danske Bank rather than a separate subsidiary.
De praktiske konsekvenser heraf er, at fra 1. april 2007 er National Irish Bank ikke længere et selvstændigt aktie-selskab under opsyn og regulering af Irish Financial Services Regulatory Authority men under det danske Finanstilsyn i stedet, eftersom NIB nu er en del af Danske Bank i stedet for et selvstændigt datterselskab.
