Assured Guaranty Ltd. Responds to Moody's Ratings Downgrade of Assured Guaranty Corp. to Aa3 and Affirmation of Aa3 Rating of Assured Guaranty Municipal Corp.

In response to the downgrade by Moody's Investors Service of the insurance financial strength rating of bond insurer Assured Guaranty Corp. (AGC) to Aa3 from Aa2 and Moody's affirmation of the Aa3 insurance financial strength rating of Assured Guaranty Municipal Corp. (AGM), Dominic Frederico, President and Chief Executive Officer of Assured Guaranty Ltd. (NYSE:AGO) ("the Company"), today made the following statement:

"We are pleased that AGC and AGM have both maintained Moody's ratings in the double-A rating category, a rating that connotes significant financial strength in today's economic environment. In assigning these ratings, Moody's has put our insured residential mortgage exposures through a revised stress loss scenario, which is based on an extremely pessimistic view of the future performance of residential mortgage exposures. Even under Moody's stressful scenario, the Assured companies' combined $12.5 billion of claims-paying resources were more than sufficient to meet all projected obligations. We are committed to maintaining the highest possible ratings and plan to implement a capital plan to meet rating agency requirements to maintain double-A ratings. Moreover, these capital initiatives, which entail external reinsurance that has already been negotiated, intercompany capital support and approximately $300 million of additional capital, are to solely support rating agency capital requirements. In the absence of true capital regulation by federal or state authorities, we believe this is in the best interests of the Company.

"In its review, Moody's noted 'our strong risk management, which has contributed to much better performance than our peers during the financial crisis' and 'our very strong competitive position in the U.S. municipal market.'

"Despite the ratings uncertainty over the past few months, demand for our guaranty products has remained strong in the U.S. municipal market, as demonstrated by our previously announced third quarter 2009 U.S. public finance new issue volume. The two direct bond insurers guaranteed a total of approximately $8.7 billion in U.S. municipal new issue volume, representing 9.6% of total par issued for the third quarter 2009. Through October 2009, both companies combined have guaranteed approximately $32.0 billion in new issues, representing 9.5% of public finance new issuance. We are confident that we will continue to provide value for issuers and investors across our markets."
