Assured Guaranty Reports Second Quarter 2004 Earnings of $0.57 Per Share

Hamilton, Bermuda—August 3, 2004.    Assured Guaranty Ltd. (NYSE: AGO) announced net income of $43.1 million, or $0.57 per diluted share, for the second quarter ended June 30, 2004, an increase of 1% compared with $42.7 million, or $0.57 per diluted share, earned in the second quarter of 2003. Operating income, which we define as net income excluding after-tax net realized gains (losses) on investments and after-tax unrealized gains (losses) on derivative financial instruments, decreased from $33.2 million in the second quarter of 2003 to $27.9 million, or $0.37 per diluted share, and included a $9.6 million or $0.13 per share after-tax expense for the initial public offering (IPO) related accelerated vesting and replacement of stock awards. Management, investors and analysts use operating income to evaluate our results of operations, as this measure highlights the underlying profitability of our business. The quarter also included a net loss of $2.4 million that affected net income, or $0.03 per diluted share, and an operating loss of $5.9 million in operating income, or $0.08 per diluted share, from our other segment, which consists of transactions and lines of business that we exited as part of our IPO that closed on April 28, 2004.

        "Assured Guaranty achieved several major accomplishments in the second quarter of 2004," stated Dominic Frederico, Chief Executive Officer of Assured Guaranty Ltd. "Our IPO was a major undertaking and took a significant amount of management time and attention during the quarter. After the IPO, our team has quickly moved back into full-time marketing and underwriting and produced strong new business production in our financial guaranty direct segment results compared to the first quarter of the year."

Analysis of Present Value of Gross Financial Guaranty Premiums Written ("PVP")(2)

($ in millions)	Second Quarter 2004		Second Quarter 2003		% Change
Financial guaranty direct	$	14.4	$	15.4	(6	)%
Financial guaranty reinsurance(3)		39.3		23.8	65
PVP	$	53.6	$	39.3	36	%

        The present value of gross financial guaranty premiums written ("PVP") in the quarter was $53.6 million, compared with $39.3 million in the second quarter of 2003. Management, equity analysts and investors use this non-GAAP measure to evaluate the value of new financial guaranty business production, as the GAAP gross premiums written measure does not reflect the present value of installment premiums on new contracts underwritten in a reporting period. See "Selected Financial Highlights" for a reconciliation of PVP to gross premiums written.

        Financial guaranty direct PVP totaled $14.4 million, down 6% over the second quarter of 2003 but up 82% from the $7.9 million generated in the first quarter of 2004. Michael Schozer, President of Assured Guaranty Corp. commented, "Second quarter production was good, given the limited time frame for marketing after the IPO. We see expanded opportunities in the marketplace compared to last year, when Assured Guaranty principally guaranteed transactions in the mortgage-backed and synthetic CDO markets, which have both slowed down considerably in 2004. For instance, 40% of second quarter 2003 PVP was in the synthetic CDO market but we had no synthetic CDO PVP in this year's quarter. Looking forward, despite weaker market conditions compared to 2003, we remain focused on executing our business plan while maintaining our underwriting discipline."

        Financial guaranty reinsurance PVP totaled $39.3 million, up 65% from the second quarter of 2003. The 65% significantly benefited from contracts in force in 2004 that were incepted in the third quarter of 2003. For the full year 2003, financial guaranty reinsurance PVP was $164.1 million. In the second quarter of 2004, we did not renew one treaty and had a reduced cession percentage on a second treaty. If these changes had been in force at April 1, 2004, PVP volume in the quarter would have been about $27.3 million. Robbin Conner, Executive Vice President of Assured Guaranty Corp. and head of the Financial Guaranty-Reinsurance segment commented, "Due to the reduced treaty cessions, we now expect that our reinsurance volumes will decline for the balance of 2004 and the first half of 2005 from the previous comparable periods. We are increasing our focus on facultative opportunities from all market participants and are pursuing additional treaty relationships."

        Robert Mills, CFO of Assured Guaranty, commented, "The second quarter's results include the financial impact of numerous strategic accomplishments in the quarter: the IPO, the exiting or close-out of lines of business in the other segment, the issuance of public senior debt and the conversion of Assured Guaranty's stock-based compensation plans. Our second quarter balance sheet and income statement are not easily compared to prior period results because of the impact of all of these transactions. I am encouraged by our results and future prospects."

Gross Premiums Written by Segment

($ in millions)		Second Quarter 2004		Second Quarter 2003		% Change
Financial guaranty direct		$	17.7	$	20.8	(15	)%
Financial guaranty reinsurance			35.8		34.0	5
Mortgage guaranty			0.9		8.5	(89	)
	Sub-total	$	54.4	$	63.3	(14	)%
Other segment			10.0		18.3	(45	)
	Total gross premium written	$	64.4	$	81.6	(21	)%

        Gross premiums written were $64.4 million in the quarter, down 21% from the prior year period, while net premiums written were ($47.4) million. Gross premiums written in our other segment, which represents our exited lines of business, were $10.0 million in the quarter, while net premiums written in this segment were ($101.4) million, due to the accounting for the unwinding of the remaining businesses exited as part of the initial public offering, including trade credit, title reinsurance and auto residual value. Excluding the other segment, gross premiums written were $54.4 million, down 14%, and net premiums written were $54.0 million, down 14%, due principally to the commutation of an excess of loss reinsurance contract and the continued run off of our mortgage quota share and single-name credit default swap books of business. Combined, these items reduced gross and net premiums written by $8.7 million in the quarter compared to the second quarter of 2003.

Net Premiums Earned by Segment

($ in millions)		Second Quarter 2004			Second Quarter 2003		% Change
Financial guaranty direct		$	16.1		$	21.2	(24	)%
Financial guaranty reinsurance			25.6			30.1	(15	)
Mortgage guaranty			15.0			9.4	60
	Sub-total	$	56.7		$	60.7	(7	)%
Other segment			(83.4	)		21.4	NMF
	Total		(26.7	)		82.1	NMF
Municipal refunding premiums			4.4			8.1	(46	)
	Net premiums earned excluding refundings	$	(31.1	)	$	74.0	NMF

        Net premiums earned were $(26.7) million in the second quarter of 2004, compared with $82.1 million in the second quarter of 2003. Excluding the other segment, net premiums earned were $56.7, down 7% from $60.7 million in the second quarter of 2003. Financial guaranty direct net premiums earned were $16.1 million, down 24%, due mainly to a $3.9 million reduction in net premiums earned on our closed book of single name corporate credit default swaps. Financial guaranty reinsurance net premiums earned were $25.6 million, down 15% from $30.1 million in the second quarter of 2003. Included in this amount were $4.4 million of municipal bond refunding premiums, compared with $8.1 million in the second quarter of 2003. Mortgage guaranty net premiums earned were $15.0 million, compared with $9.4 million in the second quarter of 2003, up 60%, reflecting the release of $8.8 million in unearned premium reserves related to an excess of loss reinsurance commutation by a client offset by a $3.0 million reduction in net premiums earned on our quota share mortgage guaranty reinsurance business compared to the second quarter of 2003.

        Investment income in the quarter was $23.5 million, down 2% compared with $24.0 million in the second quarter of 2003. The average portfolio book yield was 4.7%, compared with 5.0% in the prior

3

year on an investment portfolio of $2.0 billion at June 30, 2004. The portfolio's average credit quality remained at AA+/Aa2. IPO-related and transactions in the other segment were completed during the quarter and reduced the investment portfolio by $133 million, and increased our funds held liability by $32 million.

Consolidated GAAP Combined Ratio

		Second Quarter 2004		Second Quarter 2003
Loss ratio		289.9	%	43.6	%
Expense ratio		(149.4	)	36.1
	Combined ratio	140.5	%	79.7	%

        Consolidated loss and expense numbers are not comparable to prior quarters due to the effect of the other segment on consolidated financial results. Loss and loss adjustment expenses in the quarter were ($77.4) million, or 289.9% of net premiums earned ("loss ratio"), compared with $35.8 million or a 43.6% loss ratio in the second quarter of 2003. Assured Guaranty's profit commission expense, acquisition costs and other operating expenses were $39.9 million in the quarter, as compared to $29.6 million. The expense ratio, which is calculated by computing profit commission expense, acquisition cost and operating expenses as percent of net premiums earned is not meaningful for comparison between quarters because of the negative net premium earned in the second quarter of 2004.

        The Company's June 30, 2004 book value per share was $18.96, or $18.19 excluding accumulated other comprehensive income. Management, investors and analysts use the calculation of adjusted book value to evaluate the net present value of the Company's in-force premium and capital base. Adjusted book value(4) per share was $25.42 at June 30, 2004. Book value and adjusted book value per share growth in the current period are not comparable to prior periods as the prior periods do not include the financial impact of the issuance of $200 million of senior notes in May 2004.

        The Company's return on average equity excluding accumulated other comprehensive income (AOCI) was 12.4% in the quarter and 13.2% year to date. Management, investors and analysts use operating return on average equity, which is calculated by annualizing net income excluding after-tax net realized gains (losses) on investments and after-tax unrealized gains (losses) on derivative financial instruments by average shareholders' equity excluding accumulated other comprehensive income, to evaluate our financial performance. Operating return on average equity excluding AOCI was 8.0% in the quarter and 10.5% year to date. The $9.6 million after tax charge for the accelerated vesting of stock awards reduced the quarter's ROE by 2.8% and the operating loss for the other segment, which was largely offset by realized capital gains, reduced the quarter's ROE by 1.7%. Excluding these two items, second quarter operating ROE would have been 12.5%.

Analysis of ROE

		Second Quarter 2004		Six Months Ended 6/30/2004
ROE, excluding AOCI		12.4	%	13.2	%
Percentage impact on ROE of:
	After-tax realized gains on investments	1.8		0.9
	After-tax unrealized gains on derivatives	2.6		1.8
Operating income ROE(1)		8.0	%	10.5	%
	After-tax incentive based stock compensation expense	2.8	%	1.4	%
	After-tax other segment-related operating loss	1.7		0.4
		12.5	%	12.3	%

        Robert Mills, CFO of Assured Guaranty, added, "Although the first six months produced an operating ROE which exceeded our target, the results of the first six months benefited from one-off and close-out transactions in our principal business segments. Based on our analysis of current market and economic conditions, our split ratings and the change in two of our reinsurance relationships, we expect our 2004 ROE, excluding the second quarter charge for the accelerated vesting of stock awards and the operating loss of the other segment, to approximately 11%. Looking ahead to 2005, the continued weakness in the market combined with the reinsurance changes will place significant pressure on our ability to improve ROE, although we will be better able to assess our future prospects after the fourth quarter is completed."

        The Company will host a conference call for investors at 10:00 a.m. EDT (11:00 a.m. ADT) on Wednesday, August 4, 2004.

Footnotes:

(1)

We believe the presentation of operating income and operating income ROE enhance the understanding of our results of operations by highlighting the underlying profitability of our 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, the market interest rates, credit spreads and other factors that management cannot control or predict. Operating income ROE represents the return on average equity excluding AOCI based on operating income. These measures should not be viewed as a substitute for net income determined in accordance with generally accepted accounting principles (GAAP).

(2)

PVP, which is a non-GAAP measure, represents gross premiums related to financial guaranty contracts written in the current period, including the full amount of upfront installment premiums received and the present value of all installment premiums, discounted at 6% per year.

(3)

Due to reporting lags by our ceding companies, PVP for installment premiums from our financial guaranty reinsurance segment is reported on a one-quarter lag.

(4)

Adjusted book value, which is a non-GAAP measure, is derived by beginning with shareholder's equity (book value) and adding or subtracting the after-tax value of: the financial guaranty net unearned premium reserve; deferred acquisition costs and the present value of estimated net future installment premiums (discounted at 6)%. These adjustments will not be realized until future periods and may differ materially from the amounts used in determining adjusted book value.
