Exhibit 99.1

Press Release

Assured Guaranty Ltd. Reports Full Year 2008 Net Income of $68.9 million ($0.77 per diluted share);

Full Year 2008 Operating Income of $74.5 million ($0.84 per diluted share)

Book Value Per Share Increases 2% to $21.18

Hamilton, Bermuda, February 25, 2009 – Assured Guaranty Ltd. (NYSE: AGO) (“Assured” or “the Company”) today reported financial results for the fiscal year ended December 31, 2008. Assured reported 2008 net income of $68.9 million ($0.77 per diluted share), an increase of $372.2 million over the net loss of $303.3 million ($4.46 per diluted share) that Assured reported for 2007. The improvement in 2008 was principally due to the change in unrealized gains and losses on credit derivatives. Assured had after-tax unrealized gains on credit derivatives of $57.1 million ($0.64 per diluted share) in 2008 as compared to after-tax unrealized losses on credit derivatives of $480.0 million ($7.06 per diluted share) in 2007.

Operating income, a financial measure that is not in accordance with U.S. Generally Accepted Accounting Principles (“non-GAAP financial measure”), was $74.5 million ($0.84 per diluted share) in 2008, a decrease of 58% from $178.0 million ($2.57 per diluted share) in 2007. See the “Explanation of Non-GAAP Financial Measures” section of this press release for a definition of operating income and other non-GAAP financial measures referenced in this press release. Operating income in 2008 benefited from a $102.1 million increase in net earned premiums and a $34.5 million increase in net investment income compared to 2007 as a result of the growth of Assured’s financial guaranty business in 2008. However, the increase in net earned premiums and net investment income was more than offset by a $260.0 million increase in loss and loss adjustment expenses ($201.7 million after-tax or $2.23 per diluted share) and a $40.1 million increase in incurred losses on credit derivatives ($30.9 million after tax or $0.34 per diluted share) compared to 2007. In both periods, the majority of the loss and loss adjustment expenses and incurred losses on credit derivatives were largely associated, either directly or indirectly, with the credit deterioration of U.S. residential mortgage-backed securities (“RMBS”).

“Assured’s long-standing focus on disciplined underwriting and proactive risk management helped protect our Company from the catastrophic losses experienced by so many other leading financial institutions this year,” commented Dominic Frederico, President and Chief Executive Officer of Assured Guaranty Ltd. “We are one of the few financial institutions to report net income and operating income for the year and we also had an increase in our book value per share, despite losses on U.S. RMBS. During the quarter, the performance of our RMBS exposures deteriorated at a faster pace than we expected, which resulted in the additional loss reserves we incurred in the quarter. We

continue to aggressively pursue all of our rights and remedies under the terms of our contracts in order to minimize the ultimate net losses that we will pay on mortgage-related exposures.”

The quarter and year ended December 31, 2008 included a fair value after-tax gain of $12.0 million, or $0.13 per diluted share, and $27.8 million, or $0.31 per diluted share, respectively, related to Assured Guaranty Corp.’s committed capital securities. The quarter and year ended December 31, 2007 included a fair value after-tax gain of $5.4 million, or $0.08 per diluted share, related to Assured Guaranty Corp.’s committed capital securities.

(2)

The calculations for weighted averaged diluted shares outstanding and weighted average basic shares outstanding for GAAP are the same due to the anti-dilutive effect of options and restricted stock awards and units as a result of the net loss for both fourth quarter 2008 and 2007, and full year 2007. However, net income for full year 2008 and operating income, a non-GAAP financial measure, for all the periods presented is positive therefore the calculation of weighted average diluted shares outstanding for operating income includes the dilutive effect of options and restricted stock awards and units for all periods presented.

Shareholders’ Equity and Book Value Per Share:

Assured also announced today that its shareholders’ equity at December 31, 2008 was $1,926.2 million, an increase of 16% from $1,666.6 million at December 31, 2007. This increase was largely due to $250.0 million of net proceeds from Assured’s April 2008 equity offering to WLR Recovery Fund IV, L.P. and affiliated funds, but also benefited from a $52.8 million increase in retained earnings related to the Company’s 2008 net income less shareholders’ dividends. The Company’s book value per share, which includes the effect of the April share issuance, was $21.18 at December 31, 2008, up 2% compared to $20.85 at December 31, 2007.

The Company’s December 31, 2008 shareholders’ equity was also affected by several mark-to-market related gains and losses compared to December 31, 2007, including: a $53.7 million reduction in accumulated other comprehensive income due to unrealized capital losses on the Company’s investment assets attributable to market value changes; a $29.7 million reduction in after-tax mark-to-market unrealized losses on credit derivatives; and a $27.8 million increase in after-tax fair value gain on Assured Guaranty Corp.’s committed capital securities. The Company recorded a $57.1 million unrealized gain on credit derivatives in 2008 versus a $480.0 million loss for full year 2007, as a result of an increase in the fair value of financial guaranty contracts written in credit default swap form by the Company’s financial guaranty direct and reinsurance segments during 2008. The fair value reflects the change in the Company’s own credit cost based on the price to purchase credit protection on Assured Guaranty Corp., the Company’s financial guaranty direct subsidiary, which widened during 2008, but was partially offset by the market value decline on credit derivatives. The Company’s credit derivatives are generally held to maturity and management expects that the unrealized gain or loss on a credit derivative will reduce to zero as the exposure approaches its maturity date, unless there is a payment default on the exposure.

Shareholders’ equity excluding accumulated other comprehensive income, mark-to-market unrealized losses on credit derivatives, and the fair value gain on Assured Guaranty Corp.’s committed capital securities was $2,312.9 million, up 12% from $2,056.6 million at December 31, 2007. Shareholders' equity per share excluding these items was $25.43 per share at December 31, 2008, a decrease of 1% from $25.72 at December 31, 2007.

Assured’s adjusted book value, a non-GAAP financial measure, was $37.65 per share at December 31, 2008, an increase of 2% over adjusted book value per share of $36.85 at December 31, 2007. Adjusted book value per share excluding net unrealized losses on credit derivatives, fair value gain on Assured Guaranty Corp.’s committed capital securities and accumulated other comprehensive income was $41.91 per share at December 31, 2008, an increase of 0.4% from $41.73 at December 31, 2007.

Assured expects to file its Form 10-K filing with the U.S. Securities and Exchange Commission by the close of business on Friday, February 27, 2009. Investors should refer to this filing for the Company’s audited financial results, management’s discussion and analysis of 2008 results, Company risk factors and other information on 2008 results.

Fourth Quarter 2008

Assured also reported today its financial results for the quarter ended December 31, 2008 (“fourth quarter 2008”) as well as its fourth quarter 2008 financial supplement, which is available in the Investor Information Section of the Company’s website at www.assuredguaranty.com. Assured announced a fourth quarter 2008 net loss of $243.8 million ($2.68 per diluted share), an improvement of $16.3 million ($1.09 per diluted share) or 29% compared the net loss of $260.1 million ($3.77 per diluted share) reported for the quarter ended December 31, 2007 (“fourth quarter 2007”). The improvement in the Company’s fourth quarter 2008 results compared to the prior year period reflect a $90.5 million ($2.05 per diluted share) reduction in after-tax unrealized losses on credit derivatives that was partially offset by a $47.2 million ($0.52 per diluted share) increase in after-tax realized losses on investments and a $33.5 million ($0.49 per diluted share) reduction in operating income. The increase in after-tax realized losses on investments principally reflects other than temporary impairments of investment securities in the Company’s investment portfolio.

Fourth quarter 2008 operating income declined to $3.5 million ($0.04 per diluted share) from $37.0 million ($0.53 per diluted share) in fourth quarter 2007 due to an increase in loss and loss adjustment expenses that was greater than the significant growth in the Company’s net earned premiums and net investment income over the prior year period. The Company reported 70% growth in net earned premiums to $77.4 million and a 25% increase in investment income to $42.3 million due to the growth of the Company’s business over the last year. However, the growth in these two items was more than offset by increased loss and loss adjustment expenses, the majority of which were directly or indirectly associated with U.S. RMBS. Assured reported $90.0 million of fourth quarter 2008 pre-tax loss and loss adjustment expenses ($69.3 million after tax or $0.76 per diluted share), an increase of $72.4 million ($53.7 million after tax or $0.54 per diluted share) over fourth quarter 2007. The RMBS losses were from a variety of subcategories of RMBS collateral and were not predominantly from home equity line of credit (“HELOC”) exposures as in previous quarters but were instead largely associated with portfolio and case loss reserves established on alternative-A (“alt-A”) or closed-end second lien RMBS.

Present Value of Financial Guaranty and Credit Derivative Gross Written Premiums

Assured’s fourth quarter 2008 consolidated new business production as measured by the present value of financial guaranty and credit derivative gross written premiums (“PVP”), a non-GAAP financial measure, was $128.1 million, a 73% decrease compared to fourth quarter 2007. The financial guaranty direct segment’s fourth quarter 2008 PVP was $121.9 million, a 22% decrease from the same period last year, reflecting increased U.S. public finance production that was offset by the Company’s reduced production in the U.S. structured finance and international markets. Fourth quarter 2008 U.S. public finance PVP increased 124% to $57.4 million from $25.6 million in the prior

Income Statement Highlights:

Assured’s fourth quarter 2008 gross and net written premiums decreased 63% and 64%, respectively, compared to fourth quarter 2007. The lower premiums in fourth quarter 2008 are attributable to the 2007 Ambac reinsurance transaction, which generated $143.2 million in both gross and net written premiums in fourth quarter 2007.

Fourth quarter 2008 net earned premiums increased 70% from fourth quarter 2007 to $77.4 million, driven principally by the growth in financial guaranty direct business and by an increase in refundings in the financial guaranty reinsurance segment. Financial guaranty direct net earned premiums rose by 70% to $25.0 million in the quarter while financial guaranty reinsurance premiums rose by 135% to $51.1 million, including $24.4 million of reinsurance refundings. Fourth quarter 2008 net earned premiums excluding $25.8 million of premiums earned due to refundings ($0.17 per diluted share after tax) in both segments were $51.6 million, an increase of 18% over fourth quarter 2007 net earned premiums excluding refundings.

NM = Not meaningful

Assured’s fourth quarter 2008 net investment income rose to $42.3 million, an increase of 25% compared to fourth quarter 2007, due to higher average invested asset balances that were slightly offset by a decline in pre-tax book yields to 4.6% at December 31, 2008 from 5.0% at December 31, 2007, consistent with the decline in market interest rates over the past year.

Realized gains and other settlements on credit derivatives rose 29% in fourth quarter 2008 to $28.2 million reflecting the growth in the Company’s net par outstanding of credit derivatives and the increase in new business pricing over the prior year period. Credit derivatives are largely underwritten in Assured’s financial guaranty direct segment and, in particular, in the international and U.S. structured finance markets.

The Company’s incurred losses on credit derivatives, which reflect the change in case and portfolio loss reserves established for contracts written in credit derivative form, were $24.8 million in fourth quarter 2008 compared to $0.5 million in fourth quarter 2007. The majority of the increase was for portfolio loss reserves on alt-A and subprime U.S. RMBS exposures due to Assured’s fourth quarter 2008 downgrade of internal ratings on credit derivative contracts covering U.S. RMBS, but also included $5.2 million in case and portfolio loss reserves for non-RMBS exposures. Additional detail on the Company’s incurred losses on credit derivatives and loss and loss adjustment expenses by exposure category is available in Table 6 below.

Total Expenses

Assured’s fourth quarter 2008 total expenses were $129.9 million compared to $58.5 million in fourth quarter 2007, an increase of 122% which was largely attributable to a $72.4 million increase in pre-tax loss and loss adjustment expenses from fourth quarter 2007.

Fourth quarter 2008 pre-tax loss and loss adjustment expenses totaled $90.0 million ($69.3 million after tax or $0.76 per diluted share) and included $74.8 million directly or indirectly associated with U.S. RMBS ($52.1 million after tax or $0.57 per diluted share). Fourth quarter 2008 losses included $24.0 million of pre-tax HELOC losses, of which $17.2 million was incurred for two large Countrywide transactions underwritten in Assured’s financial guaranty direct segment during 2005 and 2007 (“direct Countrywide transactions”). The Company’s total paid losses and loss adjustment expenses on the two direct Countrywide transactions as of December 31, 2008 were $170.0 million ($130.7 million after tax) and the Company has booked a loss salvage recoverable of $59.0 million ($43.5 million after tax) against these losses as of December 31, 2008. Additional detail on the Company’s incurred losses on credit derivatives and loss and loss adjustment expenses by exposure category is available in Table 6 below.

Acquisition costs, which primarily consist of ceding commissions, brokerage fees and operating expenses that are related to the acquisition of new business, were $18.2 million, up 65% as compared to $11.0 million in fourth quarter 2007. The growth in acquisition costs is related to the increase in net earned premiums versus the prior year period, including the recognition of ceding commission expense on premiums that were earned in the quarter due to refundings.

Other operating expenses were $13.6 million in fourth quarter 2008, a 34% decrease from $20.5 million in fourth quarter 2007. Lower incentive compensation accruals which were partially offset by increased headcount and higher rental accruals over fourth quarter 2007 were the principal factors contributing to the decrease in other operating expenses.

Interest and other expenses were $7.6 million in fourth quarter 2008, an increase of 15% over the prior period, as a consequence of an increase in the interest rate margin on the Company’s committed capital securities that was required after the auction process for these securities failed in April 2008. The Company is currently paying 250 basis points over the one-month London Interbank Offered Rate as compared to 110 basis points prior to April 2008.

As detailed in Table 1, Assured’s recorded after-tax realized losses on investments of $46.8 million for fourth quarter 2008 as compared to a $0.4 million gain for fourth quarter 2007. The fourth quarter 2008 losses were attributable to the loss recognition for other than temporary impairment of securities in the Company’s investment portfolio whose market value has declined, principally due to the decline in the broad fixed income markets. These losses will be recaptured in the future if the underlying securities do not have a payment default.

FAS 163 Implementation: The Company has previously confirmed that the provisions of Financial Accounting Standard No. 163 (“FAS 163”), which addresses the methodology for establishing claims liabilities as well as other financial guaranty accounting items, is expected to have a material effect on the Company’s financial statements. The Company expects the effect of FAS 163 to be material to premiums receivable and unearned premium reserve on its balance sheet as of January 1, 2009 for the recording of future installment premiums. The Company is in the process of finalizing the impact of the adoption of FAS 163 on retained earnings for revisions to the Company’s premium revenue recognition and claims liability methodologies. The Company will disclose the impact of the adoption of FAS 163 in its 10-Q for the period ended March 31, 2009.

CIFG NA Reinsurance Transaction: On January 22, 2009, Assured Guaranty Corp. announced the closing of the reinsurance transaction with CIFG NA that was previously announced on October 23, 2008. This transaction will be recorded in the Company’s financial statements for the quarter ended March 31, 2009. Assured Guaranty Corp. is providing reinsurance to CIFG NA with respect to certain U.S. public finance and infrastructure policies (the “covered policies”) totaling approximately $13 billion of par outstanding. The covered policies principally consist of investment grade credits and do not contain any below investment grade credits, any credit default swaps, or any credits for which a loss reserve had been established by CIFG NA. In connection with the reinsurance transaction, Assured has received unearned upfront premium reserves of approximately $85 million. As previously announced, CIFG NA and Assured have agreed to work together after the closing of the reinsurance transaction to secure written agreements from the holders of each covered policy to transfer by novation the covered policy from CIFG NA to Assured. Until novated, all covered policies will remain direct guarantee obligations of CIFG NA.

Explanation of Non-GAAP Financial Measures:

This press release references several non-GAAP financial measures to assist analysts and investors in evaluating Assured’s financial results. These non-GAAP financial measures are defined in the “Explanation of Non-GAAP Financial Measures” section of the press release. In each case, the most

directly comparable GAAP financial measure, if available, is presented and a reconciliation of the non-GAAP financial measure and GAAP financial measure is provided. This presentation is consistent with how Assured’s management, analysts and investors evaluate the Company’s financial results and is comparable to estimates published by analysts in their research reports on Assured. The non-GAAP financial measures included in this press release are: operating income, present value of financial guaranty and credit derivative gross written premiums (“PVP”), net present value of estimated future installment premiums in force and adjusted book value. The following paragraphs define each non-GAAP financial measures presented in this press release and describes why they are useful for investors.

Operating income, which is a non-GAAP financial measure, is defined as net income (loss) excluding: (i) after-tax realized gains (losses) on investments; (ii) after-tax unrealized gains (losses) on credit derivatives, and (iii) the fair value adjustment of the Company’s committed capital securities, other than the Company’s net estimate of after-tax losses incurred on credit derivatives. Management believes that operating income is a useful measure for management, investors and analysts because the presentation of operating income enhances the understanding of Assured’s results of operations by highlighting the underlying profitability of Assured’s business. Realized gains (losses) on investments and unrealized gains (losses) on credit derivatives and the fair value adjustment of the Company’s committed capital securities, other than incurred losses on credit derivatives, are excluded because the amount of these gains (losses) is heavily influenced by, and fluctuates, in part, according to changes in market interest rates, credit spreads and other factors that management cannot control or predict. This measure should not be viewed as a substitute for net income (loss) determined in accordance with GAAP.

Present value of financial guaranty and credit derivative gross written premiums, or PVP, which is a non-GAAP financial measure, is defined as gross upfront and installment premiums received and the present value of gross estimated future installment premiums on insurance and credit derivative contracts written in the current period, discounted at 6% per year. Management believes that PVP is a useful measure for management, investors and analysts because it permits the evaluation of the value of new business production for Assured by taking into account the value of estimated future installment premiums on all new contracts underwritten in a reporting period, whether in insurance or credit derivative contract form, which GAAP gross premiums written and the net credit derivative premiums received and receivable portion of net realized gains and other settlements on credit derivatives (“credit derivative revenues”) do not measure. Actual future net earned or written premiums and credit derivative revenues may differ from PVP due to factors such as prepayments, amortizations, refundings, contract terminations or defaults that may or may not be influenced by market interest rates, refinancing or refunding activity, prepayment speeds, policy changes or terminations, credit defaults, or other factors that management cannot control or predict. This measure should not be viewed as a substitute for gross written premiums determined in accordance with GAAP.

Net present value of estimated future installment premiums in force, which is a non-GAAP financial measure, is defined as the present value of estimated future installment premiums from our financial guaranty and credit derivative in-force books of business, net of reinsurance, and discounted at 6%. Management believes that net present value of estimated future installment premiums in force is a useful measure for management, investors and analysts because it permits an evaluation of the Company’s future estimated financial guaranty and credit derivative installment premiums. Estimated future premiums may change from period to period due to changes in par outstanding, maturity, or other factors that management cannot control or predict that result from market interest rates, refinancing or refunding activity, prepayment speeds, policy changes or terminations, credit defaults, or other factors. There is no comparable GAAP financial measure.
