...FRANKFURT (Standard & Poor's) June 1, 2015--Standard & Poor's Ratings Services today corrected its issue rating on one series of single-name credit-linked notes issued by Commerzbank AG (A-/Watch Neg/A-2) by lowering it to 'A-' from 'A' and placing it on CreditWatch with negative implications. The international securities identification number of the issue is DE000DR6D297. The reference entity for the notes is Volkswagen AG. Due to an error, we raised the rating on the credit-linked notes to 'A' when we upgraded the long-term issuer credit rating (ICR) on Volkswagen AG to 'A' on Sept. 22, 2014, and did not place it on CreditWatch with negative implications when we placed the 'A-' long-term ratings on Commerzbank on CreditWatch with negative implications on Feb. 3, 2015.
