New Issue Rating Methodology for Mortgage Pfandbriefe

Following a successful consultation phase, we are pleased to present our new rating methodology Issue rating of mortgage Pfandbriefe (version 1.0.05, July 2019).

The methodology for Issue rating of Mortgage Pfandbriefe is available at the following link.

GBB-Rating, as the holding company of the Auditing Association of German Banks (Prüfungsverband deutscher Banken e.V.), is using this new rating methodology to expand its range of high-quality, cost-priced services to support banks in the private banking sector.
