1. Assured Guaranty's internal rating. Assured Guaranty's scale is comparable to that of the nationally recognized rating agencies. 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 has additional credit enhancement due to either (1) the existence of another security rated AAA that is subordinated to Assured Guaranty's exposure or (2) Assured Guaranty's exposure benefits 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.

Assured Guaranty's surveillance department is responsible for monitoring our portfolio of credits and maintains a list of below investment grade ("BIG") credits. The BIG credits are divided into three categories: BIG Category 1: BIG transactions showing sufficient deterioration to make material losses possible, but for which no losses have been incurred. Non-investment grade transactions on which liquidity claims have been paid are in this category. Intense monitoring and intervention is employed, with internal credit ratings reviewed quarterly. BIG Category 2: BIG transactions for which expected losses have been established but for which no unreimbursed claims have yet been paid. Intense monitoring and intervention is employed, with internal credit ratings reviewed quarterly. BIG Category 3: BIG transactions for which expected losses have been established and on which unreimbursed claims have been paid. Transactions remain in this category when claims have been paid and only a recoverable remains. Intense monitoring and intervention is employed, with internal credit ratings reviewed quarterly.

Glossary

Below are the brief descriptions of selected types of U.S. public finance, non-U.S. public finance, U.S. structured finance and non-U.S. structured finance obligations that the Company insures and reinsures. For a more complete description, please refer to Assured Guaranty Ltd.'s 10-K report.

Other public finance: primarily includes government insured student loans, government-sponsored project finance and structured municipal which includes excess of loss reinsurance on portfolios of municipal credits.

Pooled corporate obligations are structured financings backed by a pool of debt obligations. These financings are typically structured in multiple tranches (layers) from equity (first loss) through super senior (high excess). Losses on defaulted pool assets are allocated successively first to the equity tranche then to higher rated tranches.

Residential mortgage-backed and home equity: includes individual and repackaged securities backed by either prime, Alt-A, or subprime first and second lien mortgages. Alt-A Option ARMs: includes transactions where 66% or more of the collateral is comprised of mortgage loans that have the potential to negatively amortize. Alt-A First Lien: includes all transactions, other than Alt-A Option ARM transactions, where more than 50% of the collateral is comprised of mortgage loans that were originated with less than full documentation.

Consumer receivables: principally includes auto loan receivables and credit card receivables.

Commercial mortgage-backed securities: includes individual and repackaged securities backed by commercial mortgage-backed securities.

Commercial receivables: includes equipment loans or leases, fleet auto financings and franchise loans.

Structured credit: includes whole business securitizations and intellectual property securitizations. Whole business securitizations are obligations 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.

Endnotes related to non-GAAP financial measures discussed in the financial supplement:

This Financial Supplement references financial measures that are not financial measures that are in accordance with U.S. generally accepted accounting principles ("non-GAAP financial measures") which management uses in order to assist analysts and investors in evaluating Assured Guaranty Corp.'s financial results. These non-GAAP financial measures are defined below. 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 Guaranty Corp.'s management, analysts and investors evaluate Assured Guaranty Corp.'s financial results and is comparable to estimates published by analysts in their research reports on Assured Guaranty Corp.

(a) PVP or present value of new business: PVP is a non-GAAP financial measure 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% for September 30, 2009 and 6% for December 31, 2008. 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 Guaranty Corp. 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 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. For purposes of the PVP calculation, management discounts estimated future installment premiums on insurance contracts at the approximate taxable equivalent yield per year on the Company's general investment portfolio, while under ASC 944-20, "Financial Services - Insurance," these amounts are discounted at a risk free rate. Additionally, under ASC 944-20 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 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, prepayments, amortizations, refundings, contract terminations or defaults that may or may not result from changes in market interest rates, foreign exchange rates, refinancing or refundings, prepayment speeds, policy changes or terminations, credit defaults or other factors that management cannot control or predict. PVP should not be viewed as a substitute for gross written premiums determined in accordance with GAAP.

(b) Operating income: Operating incomeis a non-GAAP financial measure defined as net income (loss) attributable to Assured Guaranty Corp. adjusted for the following:

1) Elimination of the after-tax realized gains (losses) on investments;

2) Elimination of the after-tax non-credit impairment unrealized gains (losses) on credit derivatives, which are unrealized gains (losses) other than the Company's net estimate of after-tax incurred economic credit losses for credit derivatives;

3) Elimination of the after-tax unrealized gains (losses) on the Company's committed capital securities; and

4) Elimination of goodwill impairment.

Management believes that operating income is a useful measure for management, investors and analysts because the presentation of operating income enhances the understanding of the Company's results of operations by highlighting the underlying profitability of its business. Realized gains (losses) on investments, non-credit impairment unrealized gains (losses) on credit derivatives, and unrealized gains (losses) on the Company's committed capital securities are excluded because these gains (losses) are heavily influenced by, and fluctuate, 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.

(c) Operating shareholder's equity ("Operating Shareholder's Equity"): Operating shareholder's equity is a non-GAAP financial measure calculated as shareholder's equity attributable to Assured Guaranty Corp. reported under accounting principles generally accepted in the United States of America (GAAP), adjusted for the following fair value adjustments deemed to be unrelated to credit impairment. The specific adjustments are:

1) Elimination of the after-tax non-credit impairment unrealized gains (losses) on credit derivatives which are unrealized gains (losses) other than the present value of estimated economic credit losses;

2) Elimination of the after-tax unrealized gains (losses) on the Company's committed capital securities; and

3) Elimination of the after-tax unrealized gains (losses) on investment portfolios, recorded as a component of accumulated comprehensive income, excluding foreign exchange revaluation.

Management believes that operating shareholder's equity is a useful measure for management, investors and analysts because the presentation of operating ROE enhances the understanding of the Company's shareholder's equity excluding unrealized gains (losses) on investments, non-credit impairment unrealized gains (losses) on credit derivatives, and unrealized gains (losses) on the Company's committed capital securities, which are heavily influenced by, and fluctuate, 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 shareholder's equity attributable to Assured Guaranty Corp. determined in accordance with GAAP.

Operating return on equity ("Operating ROE"): Operating ROE represents operating income for the specified period divided by the average of operating shareholder's equity at the beginning and the end of the specified period. Management believes that Operating ROE is a useful measure for management, investors and analysts because the presentation of Operating ROE enhance the understanding of the Company's return on shareholder's equity by highlighting the underlying profitability relative to shareholder's equity excluding the effect of unrealized gains and losses on the Company's investment portfolio, credit derivatives and committed capital securities for both net income and shareholder's equity. Realized gains (losses) on investments, non-credit impairment unrealized gains (losses) on credit derivatives, and unrealized gains (losses) on the Company's committed capital securities are excluded because these gains (losses) are heavily influenced by, and fluctuate, 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 substitutes for ROE determined in accordance with GAAP.

(d) Adjusted Book Value: Subsequent to the adoption of ASC 944-20 on January 1, 2009, adjusted book value, which is a non-GAAP financial measure, is calculated as shareholder's equity attributable to Assured Guaranty Corp. less after-tax fair value adjustments deemed to be non-economic, plus after-tax unearned premium reserves net of prepaid reinsurance and deferred acquisition costs, plus the after-tax present value of estimated future revenues on contracts written in credit derivative contract form. The specific adjustments to shareholder's equity attributable to Assured Guaranty Corp. are:

1) Elimination of the after-tax non-credit impairment unrealized gains (losses) on credit derivatives other than the present value of estimated economic credit losses;

2) Elimination of the after-tax unrealized gains (losses) on the Company's committed capital securities;

3) Elimination of the after-tax unrealized gains (losses) on investment portfolios, recorded as a component of accumulated comprehensive income, excluding foreign exchange revaluation,

4) Elimination of after-tax deferred acquisition costs,

5) Addition of the after-tax net present value of estimated future revenue on credit derivatives in force, less future ceding commissions and premium taxes, discounted at 6% for September 30, 2009 and 6% for December 31, 2008;

6) Addition of the after-tax value of the unearned premium reserve on financial guaranty contracts in excess of expected loss, net of prepaid reinsurance premiums; and

7) Addition of the after-tax value of unearned premium reserve on credit derivatives net of prepaid reinsurance.

Management believes that adjusted book value is a useful measure for management, equity analysts and investors because the calculation of adjusted book value permits an evaluation of the net present value of the Company's in force premiums and shareholder's equity. The premiums described above will be earned in future periods, but may differ materially from the estimated amounts used in determining current adjusted book value due to changes in market interest rates, foreign exchange rates, refinancing or refunding activity, prepayment speeds, policy changes or terminations, credit defaults and other factors that management cannot control or predict. This measure should not be viewed as a substitute for shareholder's equity attributable to Assured Guaranty Corp. determined in accordance with GAAP.

(e) Net present value of estimated future revenue on credit derivatives in force: Net present value of estimated installment premiums on credit derivatives in force is a non-GAAP financial measure defined as the present value of estimated future revenue from our credit derivative in-force books of business, net of reinsurance and discounted at 6% for September 30, 2009 and 6% for December 31, 2008. Management believes that net present value of estimated future revenue in force is a useful measure for management, investors and analysts because it permits an evaluation of the value of future estimated credit derivative revenue. 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, foreign exchange rates, refinancing or refunding activity, prepayment speeds, policy changes or terminations, credit defaults, or other factors. There is no comparable GAAP financial measure.

(f) Expense Ratio: Expense ratio is calculated by dividing the sum of ceding commissions expense (income), profit commission expense, acquisition costs and operating expenses by net earned premiums plus net credit derivative premiums earned included in realized gains and other settlements on credit derivatives.
