Split AAA rating affirmed for credit wrappers
The two remaining AAA-rated credit wrappers - Assured Guaranty Corp and Assured Guaranty Municipal Corp (formerly Financial Security Assurance) had their 'AAA' credit and financial strength ratings from S&P affirmed with a negative outlook. Moody's rates the pair 'Aa3/Negative' and Fitch withdrew its ratings at the end of February. S&P said Assured Guaranty and Assured Guaranty Municipal maintain a dominant position in the bond insurance industry as well as a strong margin of safety. The companies also have a proven track record of underwriting discipline.
