Aareal Bank has completed its acquisition of Düsseldorfer Hypothekenbank for around €162m ($185m). The transaction will lead to a positive one-off effect, which will boost Aareal's 2018 profit by around €52m ($59m). The Düsseldorf-based mortgage lender no longer originates new property finance business, and has been undergoing an orderly wind-down process since 2015.
