Bayerische Landesbank will launch a EUR2.5 billion commercial mortgage-backed securitization, one of the largest-ever from Germany, within the next 45 days. The deal, called Nymphenberg, will securitize commercial property loans from seven European countries, according to a banker involved with the deal. The deal will be structured using derivatives, but the final structure has not been determined. Commerzbank Securities is the lead manager.
