Prior to fourth quarter 2010, the ratio of average current credit enhancement for Trust Preferred Pooled Corporate Obligations was based on the value of the collateral as reported by the trustees, which for non-performing or low-rated collateral varied by transaction in accordance with the individual transaction documents. Beginning fourth quarter 2010, Assured Guaranty has made the measure consistent across transactions, assigning a value of 100% of the par to all performing securities, applying a standard haircut for restructured performing collateral, assigning recovery assumptions for defaulted collateral by collateral type, and making additional negative adjustments for transactions where the notional amount of interest rate hedges materially exceeds the amount of performing collateral requiring hedges.

Below Investment Grade Exposures (2 of 5) (in millions) Assured Guaranty's surveillance department is responsible for monitoring our portfolio of credits and maintains a list of BIG credits. During the fourth quarter of 2010 the Company revised the definitions of the three BIG surveillance categories to more closely track its view of whether a transaction is expected to experience a loss, without regard to whether the probability weighted expected loss exceeded the unearned premium reserve. While the revisions resulted in a number of transactions moving between BIG categories, the Company estimates that the revisions had a relatively small impact on the totals in each category. BIG Category 1: Below investment grade transactions showing sufficient deterioration to make lifetime losses possible, but for which none are currently expected. Transactions on which claims have been paid but are expected to be fully reimbursed (other than investment grade transactions on which only liquidity claims have been paid) are in this category. BIG Category 2: Below investment grade transactions for which lifetime losses are expected but for which no claims (other than liquidity claims) have yet been paid. BIG Category 3: Below investment grade transactions for which lifetime losses are expected and on which claims (other than liquidity claims) have been paid. Transactions remain in this category when claims have been paid and only a recoverable remains. Financial Guaranty Insurance and Credit Derivatives Surveillance Categories Page 25

Glossary Net Par Outstanding and Internal Ratings Internal Rating for the Company’s ratings scale is similar to that used by the nationally recognized statistical rating organizations; however, the ratings in the tables may not be the same as ratings assigned by any such rating agency. The super senior category, which is not generally used by rating agencies, is used by the Company in instances where Assured Guaranty's AAA-rated exposure on its internal rating scale has additional credit enhancement due to either (a) the existence of another security rated AAA that is subordinated to Assured Guaranty's exposure or (b) Assured Guaranty's exposure benefiting from a different form of credit enhancement that would pay any claims first in the event that any of the exposures incurs a loss, and such credit enhancement, in management's opinion, causes Assured Guaranty's attachment point to be materially above the AAA attachment point. Net par outstanding is insured par exposure net of reinsurance cessions. Performance Indicators The performance information described below is obtained from sources such as Intex, Bloomberg and/or provided by the trustee and may be subject to restatement or correction: 60+ Day Delinquencies are defined as loans that are greater than 60 days delinquent and all loans that are in foreclosure, bankruptcy or real estate owned divided by current collateral balance. Average Credit Enhancement is intended to provide a measure of the amount of equity and/or subordinated tranches that are junior in the capital structure to Assured Guaranty’s exposure, expressed as a percentage of the total transaction size, and reflects any reduction of that credit support resulting from defaults or other factors. For transactions where excess spread may be available to absorb certain losses, the amounts shown do not include any benefit from excess spread. The calculation methodologies differ for the various asset classes to reflect differences in transaction structures in order to provide a measure that management believes is comparable across asset classes. Cumulative Losses are defined as net charge-offs on the underlying loan collateral divided by the original collateral balance. Pool Factor is the percentage of the current collateral balance divided by the original collateral balance of the transactions at inception. Subordination represents the sum of subordinate tranches and overcollateralization, expressed as a percentage of total transaction size, and does not include any benefit from excess spread collections that may be used to absorb losses. Many of the closed-end second lien RMBS transactions insured by the Company have unique structures whereby the collateral may be written down for losses without a corresponding write-down of the obligations insured by the Company. Many of these transactions are currently undercollateralized, with the principal amount of collateral being less than the principal amount of the obligation insured by the Company. The Company is not required to pay principal shortfalls until legal maturity (rather than making timely principal payments), and takes the undercollateralization into account when estimating expected losses for these transactions. Sectors Below are brief descriptions of selected types of public and structured finance obligations that the Company insures and reinsures.

Public Finance: General Obligation Bonds are full faith and credit bonds that are issued by states, their political subdivisions and other municipal issuers, and are supported by the general obligation of the issuer to pay from available funds and by a pledge of the issuer to levy ad valorem taxes in an amount sufficient to provide for the full payment of the bonds. Tax-Backed Bonds are obligations that are supported by the issuer from specific and discrete sources of taxation. They include tax-backed revenue bonds, general fund obligations and lease revenue bonds. Tax-backed obligations may be secured by a lien on specific pledged tax revenues, such as a gasoline or excise tax, or incrementally from growth in property tax revenue associated with growth in property values. These obligations also include obligations secured by special assessments levied against property owners and often benefit from issuer covenants to enforce collections of such assessments and to foreclose on delinquent properties. Lease revenue bonds typically are general fund obligations of a municipality or other governmental authority that are subject to annual appropriation or abatement; projects financed and subject to such lease payments ordinarily include real estate or equipment serving an essential public purpose. Bonds in this category also include moral obligations of municipalities or governmental authorities. Municipal Utility Bonds are obligations of all forms of municipal utilities, including electric, water and sewer utilities and resource recovery revenue bonds. These utilities may be organized in various forms, including municipal enterprise systems, authorities or joint action agencies. Transportation Bonds include a wide variety of revenue-supported bonds, such as bonds for airports, ports, tunnels, municipal parking facilities, toll roads and toll bridges. Healthcare Bonds are obligations of healthcare facilities, including community-based hospitals and systems, as well as of health maintenance organizations and long-term care facilities. Higher Education Bonds are obligations secured by revenue collected by either public or private secondary schools, colleges and universities. Such revenue can encompass all of an institution’s revenue, including tuition and fees, or in other cases, can be specifically restricted to certain auxiliary sources of revenue. Page 37

Glossary (continued) Sectors (continued) Infrastructure Bonds include obligations issued by a variety of entities engaged in the financing of infrastructure projects, such as roads, airports, ports, social infrastructure and other physical assets delivering essential services supported by long-term concession arrangements with a public sector entity. Investor-Owned Utility Bonds are obligations primarily backed by investor-owned utilities, first mortgage bond obligations of for-profit electric or water utilities providing retail, industrial and commercial service, and also include sale-leaseback obligation bonds supported by such entities. Housing Revenue Bonds are obligations relating to both single and multi-family housing, issued by states and localities, supported by cash flow and, in some cases, insurance from entities such as the Federal Housing Administration. Regulated Utilities Obligations are issued by government-regulated providers of essential services and commodities, including electric, water and gas utilities. The majority of the Company’s international regulated utility business is conducted in the United Kingdom. Pooled Infrastructure Obligations are synthetic asset-backed obligations that take the form of CDS obligations or credit-linked notes that reference either infrastructure finance obligations or a pool of such obligations, with a defined deductible to cover credit risks associated with the referenced obligations. Other Public Finance primarily includes government insured student loans, government-sponsored project finance and structured municipal transactions, which includes excess of loss reinsurance on portfolios of municipal credits. Structured Finance: Pooled Corporate Obligations are securities primarily backed by various types of corporate debt obligations, such as secured or unsecured bonds, bank loans or loan participations and trust preferred securities. These securities are often issued in ‘‘tranches,’’ with subordinated tranches providing credit support to the more senior tranches. The Company’s financial guaranty exposures generally are to the more senior tranches of these issues. Residential Mortgage-Backed Securities (‘‘RMBS’’) and Home Equity Securities are obligations backed by closed-end first mortgage loans and closed- and open-end second mortgage loans or home equity loans on one-to-four family residential properties, including condominiums and cooperative apartments. First mortgage loan products in these transactions include fixed rate, adjustable rate (‘‘ARM’’) and option adjustable-rate (‘‘Option ARM’’) mortgages. The credit quality of borrowers covers a broad range, including ‘‘prime’’, ‘‘subprime’’ and ‘‘Alt-A’’. A prime borrower is generally defined as one with strong risk characteristics as measured by factors such as payment history, credit score, and debt-to-income ratio. A subprime borrower is a borrower with higher risk characteristics, usually as determined by credit score and/or credit history. An Alt-A borrower is generally defined as a prime quality borrower that lacks certain ancillary characteristics, such as fully documented income. Additional insured obligations within RMBS include Home Equity Lines of Credit (“HELOCs”), which refers to a type of residential mortgage-backed transaction backed by second-lien loan collateral consisting of home equity lines of credit. U.S. Prime First Lien is a type of residential mortgage-backed securities transaction backed primarily by prime first-lien loan collateral plus an insignificant amount of other miscellaneous RMBS transactions. CBOs/CLOs (collateralized bond obligations and collateralized loan obligations) are asset-backed securities largely backed by noninvestment grade/high yield collateral. Commercial Mortgage-Backed Securities (‘‘CMBS’’) are obligations backed by pools of commercial mortgages. The collateral supporting CMBS include office, multifamily, retail, hotel, industrial and other specialized or mixed-use properties. Financial Products is the guaranteed investment contracts ("GICs") portion of the former Financial Products Business of AGMH. AGM has issued financial guaranty insurance policies on the GICs and in respect of the GICs business that cannot be revoked or cancelled. Assured Guaranty is indemnified against exposure to the former financial products business by Dexia SA and certain of its affiliates. In addition, the French and Belgian governments have issued guaranties in respect of the GICs portion of the financial products business. The financial products business is currently being run off. Consumer Receivables Securities are obligations backed by non-mortgage consumer receivables, such as automobile loans and leases, credit card receivables and other consumer receivables. Commercial Receivables Securities are obligations backed by equipment loans or leases, fleet auto financings, business loans and trade receivables. Credit support is derived from the cash flows generated by the underlying obligations, as well as property or equipment values as applicable. Insurance Securitization Securities are obligations secured by the future earnings from pools of various types of insurance/reinsurance policies and income produced by invested assets. Structured Credit Securities include program-wide credit enhancement for commercial paper conduits in the U.S., and securities issued in whole business securitizations and intellectual property securitizations. Program-wide credit enhancement generally involves insuring against the default of ABS in a bank-sponsored commercial paper conduit. Securities issued in whole business and intellectual property securitizations are backed by revenue-producing assets sold to a limited-purpose company by an operating company, including franchise agreements, lease agreements, intellectual property and real property. Other Structured Finance Securities are obligations backed by assets not generally described in any of the other described categories. One such type of asset is a tax benefit to be realized by an investor in one of the Federal or state programs that permit such investor to receive a credit against taxes (such as Federal corporate income tax or state insurance premium tax) for making qualified investments in specified enterprises, typically located in designated low-income areas.

Non-GAAP Financial Measures The Company references financial measures that are not in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Assured Guaranty’s management and board of directors utilize non-GAAP measures in evaluating the Company’s financial performance and as a basis for determining senior management incentive compensation. By providing these non-GAAP financial measures, investors, analysts and financial news reporters have access to the same information that management reviews internally. In addition, Assured Guaranty’s presentation of non-GAAP financial measures is consistent with how analysts calculate their estimates of Assured Guaranty’s financial results in their research reports on Assured Guaranty and with how investors, analysts and the financial news media evaluate Assured Guaranty’s financial results. The following paragraphs define each non-GAAP financial measure and describe why it is useful. A reconciliation of the non-GAAP financial measure and the most directly comparable GAAP financial measure, if available, is presented within this financial supplement. Non-GAAP financial measures should not be viewed as substitutes for their most directly comparable GAAP measures. Operating Income: Management believes that operating income is a useful measure because it clarifies the understanding of the underwriting results of the Company’s financial guaranty insurance business, and also includes financing costs and net investment income, and enables investors and analysts to evaluate the Company’s financial results as compared with the consensus analyst estimates distributed publicly by financial databases. Operating income is defined as net income (loss) attributable to Assured Guaranty Ltd., as reported under GAAP, adjusted for the following: 1) Elimination of the after-tax realized gains (losses) on the Company’s investments, except for gains and losses on securities classified as trading. The timing of realized gains and losses, which depends largely on market credit cycles, can vary considerably across periods. The timing of sales is largely subject to the Company’s discretion and influenced by market opportunities, as well as the Company’s tax and capital profile. Trends in the underlying profitability of the Company’s business can be more clearly identified without the fluctuating effects of these transactions. 2) Elimination of the after-tax non-credit-impairment unrealized fair value gains (losses) on credit derivatives, which is the amount in excess of the present value of the expected estimated economic credit losses and non-economic payments. Such fair value adjustments are heavily affected by, and in part fluctuate with, changes in market interest rates, credit spreads and other market factors and are not expected to result in an economic gain or loss. Additionally, such adjustments present all financial guaranty contracts on a more consistent basis of accounting, whether or not they are subject to derivative accounting rules. 3) Elimination of the after-tax fair value gains (losses) on the Company’s committed capital securities. Such amounts are heavily affected by, and in part fluctuate with, changes in market interest rates, credit spreads and other market factors and are not expected to result in an economic gain or loss. 4) Elimination of the after-tax foreign exchange gains (losses) on revaluation of net premium receivables. Long-dated receivables constitute a significant portion of the net premium receivable balance and represent the present value of future contractual or expected collections. Therefore, the current period’s foreign exchange revaluation gains (losses) are not necessarily indicative of the total foreign exchange gains (losses) that the Company will ultimately recognize. 5) Elimination of the effects of consolidating certain financial guaranty VIEs in order to present all financial guaranty contracts on a more consistent basis of accounting, whether or not GAAP requires consolidation. GAAP requires the Company to consolidate certain VIEs that have issued debt obligations insured by the Company even though the Company does not own such VIEs. Operating Shareholders’ Equity: Management believes that operating shareholders’ equity is a useful measure because it presents the equity of Assured Guaranty Ltd. with all financial guaranty contracts accounted for on a more consistent basis and excludes fair value adjustments that are not expected to result in economic loss. Many investors, analysts and financial news reporters use operating shareholders’ equity as the principal financial measure for valuing Assured Guaranty Ltd.’s current share price or projected share price and also as the basis of their decision to recommend, buy or sell Assured Guaranty Ltd.’s common shares. Many of the Company’s fixed income investors also use operating shareholders’ equity to evaluate the Company’s capital adequacy. Operating shareholders’ equity is the basis of the calculation of adjusted book value (see below). Operating shareholders’ equity is defined as shareholders’ equity attributable to Assured Guaranty Ltd. , as reported under GAAP, adjusted for the following: 1) Elimination of the effects of consolidating certain VIEs in order to present all financial guaranty contracts on a more consistent basis of accounting, whether or not GAAP requires consolidation. GAAP requires the Company to consolidate certain VIEs that have issued debt obligations insured by the Company even though the Company does not own such VIEs. 2) Elimination of the after-tax non-credit-impairment unrealized fair value gains (losses) on credit derivatives, which is the amount in excess of the present value of the expected estimated economic credit losses and non-economic payments. Such fair value adjustments are heavily affected by, and in part fluctuate with, changes in market interest rates, credit spreads and other market factors and are not expected to result in an economic gain or loss. 3) Elimination of the after-tax fair value gains (losses) on the Company’s committed capital securities. Such amounts are heavily affected by, and in part fluctuate with, changes in market interest rates, credit spreads and other market factors and are not expected to result in an economic gain or loss. 4) Elimination of the after-tax unrealized gains (losses) on the Company’s investments, that are recorded as a component of accumulated other comprehensive income ("AOCI") (excluding foreign exchange revaluation). The AOCI component of the fair value adjustment on the investment portfolio is not deemed economic because the Company generally holds these investments to maturity and therefore will not recognize an economic loss. Operating return on equity (‘‘Operating ROE’’): Operating ROE represents operating income for a specified period divided by the average of operating shareholders’ equity at the beginning and the end of that period. Management believes that operating ROE is a useful measure to evaluate the Company’s return on invested capital. Many investors, analysts and members of the financial news media use operating ROE to evaluate Assured Guaranty Ltd.’s share price and as the basis of their decision to recommend, buy or sell the Assured Guaranty Ltd. common shares. Quarterly and year-to-date operating ROE are calculated on an annualized basis. Page 39

Non-GAAP Financial Measures (continued) Adjusted Book Value: Management believes that adjusted book value is a useful measure because it enables an evaluation of the net present value of the Company’s in-force premiums and revenues in addition to operating shareholders’ equity. The premiums and revenues included in adjusted book value will be earned in future periods, but actual earnings may differ materially from the estimated amounts used in determining current adjusted book value due to changes in, foreign exchange rates, refinancing or refunding activity, prepayment speeds, terminations, credit defaults and other factors. Many investors, analysts and financial news reporters use adjusted book value to evaluate Assured Guaranty Ltd.’s share price and as the basis of their decision to recommend, buy or sell the Assured Guaranty Ltd. common shares. Adjusted book value is operating shareholders’ equity, as defined above, further adjusted for the following: 1) Elimination of after-tax deferred acquisition costs. These amounts represent net deferred expenses that have already been paid or accrued and will be expensed in future accounting periods. 2) Addition of the after-tax net present value of estimated net future credit derivative revenue. See below. 3) Addition of the after-tax value of the unearned premium reserve on financial guaranty contracts in excess of expected loss to be expensed, net of reinsurance. This amount represents the expected future net earned premiums, net of expected losses to be expensed. Net expected losses to be expensed are not reflected in GAAP equity. Net present value of estimated net future credit derivative revenue: Management believes that this amount is a useful measure because it enables an evaluation of the value of future estimated credit derivative revenue. There is no corresponding GAAP financial measure. This amount represents the present value of estimated future revenue from the Company’s credit derivative in-force book of business, net of reinsurance, ceding commissions and premium taxes for contracts without expected economic losses, and is discounted at 6% (which represents the Company’s tax-equivalent pre-tax investment yield on its investment portfolio). Estimated net future credit derivative revenue may change from period to period due to changes in foreign exchange rates, prepayment speeds, terminations, credit defaults or other factors that affect par outstanding or the ultimate maturity of an obligation. PVP or present value of new business production: Management believes that PVP is a useful measure because it enables the evaluation of the value of new business production for Assured Guaranty by taking into account the value of estimated future installment premiums on all new contracts underwritten in a reporting period as well as premium supplements and additional installment premium on existing contracts as to which the issuer has the right to call the insured obligation but has not exercised such right, 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 settlement on credit derivatives (“Credit Derivative Revenues”) do not adequately measure. PVP in respect of insurance and credit derivative contracts written in a specified period is defined as gross upfront and installment premiums received and the present value of gross estimated future installment premiums, in each case, discounted at 6% (the Company’s tax-equivalent pre-tax investment yield on its investment portfolio). For purposes of the PVP calculation, management discounts estimated future installment premiums on insurance contracts at 6%, while under GAAP, these amounts are discounted at a risk free rate. Additionally, under GAAP, management records future installment premiums on financial guaranty insurance contracts covering non-homogeneous pools of assets based on the contractual term of the transaction, whereas for PVP purposes, management records an estimate of the future installment premiums the Company expects to receive, which may be based upon a shorter period of time than the contractual term of the transaction. Actual future net earned or written premiums and Credit Derivative Revenues may differ from PVP due to factors including, but not limited to, changes in foreign exchange rates, refinancing or refunding activity, prepayment speeds, terminations, credit defaults, or other factors that affect par outstanding or the ultimate maturity of an obligation.
