Assured Guaranty Ltd. (NYSE:AGO) (“Assured Guaranty” or the “Company”), the holding company for Assured Guaranty Corp. and Financial Security Assurance Inc. (“FSA”), announced today that, pending regulatory approval, it will change the name of its subsidiary FSA to Assured Guaranty Municipal Corp. The Company also plans to change the names of the FSA companies worldwide.

Assured Guaranty acquired FSA on July 1, 2009, expanding its presence in the bond insurance industry by offering issuers and investors the financial strength and flexibility of two separately capitalized bond insurers. Assured Guaranty Municipal Corp., formerly FSA, now serves the municipal market exclusively, and Assured Guaranty Corp. provides financial guaranty insurance to both the municipal and structured finance sectors.

Dominic Frederico, President and Chief Executive Officer of Assured Guaranty said, “Since completing the acquisition, we have been contemplating this name change to highlight the role of the municipal-only bond insurance company and to better communicate that we are offering municipal bond issuers and investors a choice between two proven, financially strong guarantors. With the only established bond insurers to have come through the recession in strong capital positions, the Assured Guaranty family of companies, which now includes Assured Guaranty Corp., Assured Guaranty Municipal Corp. and Assured Guaranty Re Ltd. (licensed and operating exclusively in Bermuda), remain committed to the municipal market and have the capital resources to meet its needs.

“We also see an important role for Assured Guaranty Corp. to assist in the recovery of the structured finance sector as the economy improves. Our value proposition, which goes beyond the guaranty and includes providing liquidity and valuation, as well as credit analysis, surveillance, and, if necessary, remediation, is more necessary than ever given the current economic environment,” he added.

Assured Guaranty has continued to see a strong demand for its financial guaranty products in the U.S. municipal market throughout 2009 as demonstrated by its 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. Year-to date, both companies combined have guaranteed approximately $32.0 billion in new issues, representing 9.5% of public finance new issuance.

Information on Assured Guaranty Municipal Corp., formerly FSA, is currently available at www.fsa.com. On or about November 18, 2009, information on the FSA web site will be migrated to the Assured Guaranty web site at www.assuredguaranty.com.
