OVERVIEW We corrected to 'AAA' our rating on Helaba's €50 million floating-rate public sector covered bonds due Dec. 20, 2017. We incorrectly assigned the initial rating as 'A' in December 2007 due to an administrative error. FRANKFURT (Standard&Poor's) Aug. 13, 2009--Standard&Poor's Ratings Services today corrected an error relating to its rating on the €50 million floating-rate public sector covered bonds (Öffentlicher Pfandbrief) due Dec. 20, 2017 issued by Germany-based Landesbank Hessen-Thueringen Girozentrale (Helaba). Helaba issued these public sector covered bonds in December 2007 and we assigned a 'A' rating to the bonds, incorrectly classifying them as unsecured. However, we should have classified the bonds as senior secured covered bonds and assigned a 'AAA' rating. RELATED RESEARCH
