Fitch Rates Assured Guaranty's $172.5MM Sr Debt Issue 'A'; Watch Evolving

NEW YORK--(Business Wire)--
Fitch Ratings assigns an 'A' rating, Rating Watch Evolving, to the $172.5
million senior unsecured note issuance completed by Assured Guaranty US Holdings
Inc. (AGUSH), a subsidiary of Assured Guaranty Ltd. (NYSE: AGO). The new notes
are fully and unconditionally guaranteed by Assured Guaranty Ltd. (AGL).

The notes, which will be due June 1, 2014, have been pledged by investors to
collateralize their obligations under purchase contracts issued by AGL. The
purchase contracts obligate the investors to purchase from AGL, no later than
June 1, 2012, a number of common shares, subject to a predefined formula. As
such, the notes are meant to constitute a form of mandatory convertible
securities.

Per Fitch's criteria report 'Equity Credit for Hybrids & Other Capital
Securities,' dated June 25, 2008, the instruments have been analyzed under Track
B, and considered class A securities with 0% equity credit for the first two
years, and class C securities with 50% equity credit for the third year.

The proceeds of the offering, as well as a concurrent $487 million equity
offering, will be used toward payment of the purchase price for the previously
announced acquisition of Financial Security Assurance Holdings Inc. (FSA), as
well as for general corporate purposes.

On May 4, 2009, Fitch downgraded all of its ratings for AGL and its subsidiaries
and placed the ratings on Watch Evolving. In resolving the Rating Watch, Fitch
will continue to monitor credit developments in AGL and its subsidiaries'
insured portfolio, any efforts undertaken by AGL to enhance its overall capital
and risk position, as well as the management of FSA post-acquisition and its
implications with respect to franchise strength and capital. Fitch also notes
that it continues to consider overall developments in the markets for financial
guaranty insurance, which remain highly fluid.
