Prior to 2006, PVP for both treaty and facultative reinsurance installment premiums in our financial guaranty reinsurance segment was reported on a one-quarter lag.

New business production as measured by PVP, a non-GAAP financial measure, totaled $127.4 million in the third quarter of 2006, an increase of 106% from $61.9 million in the third quarter of 2005. The financial guaranty direct segment generated $90.9 million of PVP, a 131% increase over third quarter 2005 PVP of $39.4 million, reflecting strong new business production in each of the Company’s three markets: U.S. public finance, U.S. structured finance and international. International activity was particularly strong; PVP for this line of business rose 379% over the third quarter of 2005. Financial guaranty reinsurance PVP in the third quarter of 2006 was $36.5 million, an increase of 62% from $22.5 million in the third quarter of 2005, reflecting stronger international activity as well as an increase in transactions with PVP greater than $1 million.

Net written premiums in the financial guaranty direct segment increased 71% to $41.5 million, over the $24.2 million reported in the prior year period, reflecting growth in all three markets. Third quarter 2006 financial guaranty reinsurance net written premiums were $29.7 million, an increase of 9% over the third quarter of 2005, reflecting growth in premiums in all three financial guaranty reinsurance markets.

Assured Guaranty reported a consolidated underwriting gain of $21.6 million in the third quarter of 2006 compared to $25.3 million in the third quarter of 2005, which included a reduction in financial

guaranty direct portfolio loss reserves due to the run-off of business written prior to the Company’s initial public offering and the updating of rating agency default assumptions used in the Company’s portfolio reserving methodology. As a result, the Company’s consolidated combined ratio increased to 58.4% in the third quarter of 2006 from 53.5% in the third quarter of 2005. The reduction in the consolidated underwriting gain was also due to a reduction in net earned premiums in the financial guaranty reinsurance segment due to the non-renewal of treaty reinsurance contracts in 2005.

The underwriting gain for the financial guaranty direct segment decreased to $7.7 million in the third quarter of 2006 compared to $8.8 million in the third quarter of 2005. Our growth in net earned premiums was offset by a reduced benefit to loss and loss adjustment expenses, as the segment reported a $0.3 million benefit to loss and loss adjustment expenses in the third quarter of 2006 compared to a $4.0 million benefit in the prior year period from the portfolio loss reserves reduction discussed above. The financial guaranty direct combined ratio increased to 64.4% from 51.8% in the third quarter of 2005, due to the reduced benefit from in loss and loss adjustment expenses.

The underwriting gain for the financial guaranty reinsurance segment was $10.1 million in the third quarter of 2006, down from an underwriting gain of $12.8 million in the third quarter of 2005, due to a $6.6 million decrease in net earned premiums compared to the prior year; the segment’s combined ratio was slightly higher at 60.4% compared to 60.1% in the third quarter of 2005.

The mortgage guaranty segment’s underwriting gain was $2.9 million in the third quarter of 2006, up from $2.4 million in the third quarter of 2005, principally due to higher net earned premiums. This resulted in a decrease in the segment’s combined ratio to 40.1% compared to 44.4% in the third quarter of 2005.

The other segment generated an underwriting gain of $1.0 million in the third quarter of 2006, compared to an underwriting gain of $1.3 million in the third quarter of 2005; both of these underwriting gains were associated with loss recoveries on business exited prior to the Company’s IPO.

Explanation of Non-GAAP Financial Measures:

The following section defines 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 excluding after-tax realized gains (losses) on investments and after-tax unrealized gains (losses) on derivative financial instruments. We believe operating income is a useful measure for management, equity analysts and investors because the presentation of operating income enhances the understanding of our results of operations by highlighting the underlying profitability of our insurance business. We exclude net realized gains (losses) on investments and net unrealized gains (losses) on derivative financial instruments because the amount of these gains (losses) is heavily influenced by, and fluctuates in part according to, 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 determined in accordance with GAAP.

Adjusted book value, which is a non-GAAP financial measure, is defined as shareholders’ equity (book value) plus the after-tax value of the financial guaranty and mortgage guaranty unearned premium reserve net of prepaid reinsurance premiums and deferred acquisition costs plus the net present value of estimated future installment premiums in force, less future ceding commissions, after-tax, discounted at 6%. We believe 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 capital base. 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, refinancing or refunding activity, pre-payment 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 book value 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 financial guaranty and mortgage guaranty installment premiums from our in-force book of business, net of reinsurance and discounted at 6%. We believe net present value of estimated future installment premiums in force is a useful measure for management, equity analysts and investors because it permits an evaluation of the value of future estimated 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, pre-payment speeds, policy changes or terminations, credit defaults, or other factors. There is no comparable GAAP financial measure.

Present value of financial guaranty and mortgage guaranty 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 contracts written in the current period, discounted at 6% per year. We believe PVP is a useful measure for management, equity analysts and investors because it permits the evaluation of the value of new business production for Assured Guaranty by taking into account the value of estimated future installment premiums on new contracts underwritten in a reporting period, which GAAP gross premiums written does not adequately measure. Actual future net earned or written premiums 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, pre-payment 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.

For adjusted book value, net present value of estimated future installment premiums in force and present value of financial guaranty and mortgage guaranty gross written premiums or PVP we use 6% as the present value discount rate because it is the approximate taxable equivalent yield on our investment portfolio for the periods presented.
