ABK AMBAC Fincl and MBIA ratings lowered at S&P (2.30 -0.21) -Update-
S&P lowered its financial strength ratings on Ambac Assurance and MBIA Insurance(MBI) to 'AA' from 'AAA' and placed the ratings on CreditWatch with negative implications. The ratings on the holding companies, Ambac Financial Group and MBIA have also been lowered to 'A' and 'A-' from 'AA' and 'AA-', respectively, and placed on CreditWatch with negative implications. The rating actions on the cos reflect belief that these entities will face diminished public finance and structured finance new business flow and declining financial flexibility. In addition, S&P believes continuing deterioration in key areas of the U.S. residential mortgage sector and related CDO structures will place increasing pressure on capital adequacy. The 'AA' financial strength ratings of these companies are supported by currently sound claims paying ability and liquidity levels in our opinion. Resolution of the negative CreditWatch will be dependent on clarification of ultimate potential losses as well as future business prospects, the outcome of strategic business decisions, and potential regulatory developments.
