Platinum Underwriters Holdings, Ltd. and Subsidiaries

Notes to the Condensed Consolidated Financial Statements (Unaudited)

For the Three Months Ended March 31, 2008 and 2007

1. Basis of Presentation

Platinum Underwriters Holdings, Ltd. ("Platinum Holdings") is a Bermuda holding company organized in 2002. Platinum Holdings and its subsidiaries (the "Company") operate through two licensed reinsurance subsidiaries: Platinum Underwriters Bermuda, Ltd. ("Platinum Bermuda") and Platinum Underwriters Reinsurance, Inc. ("Platinum US"). The terms "we", "us", and "our" also refer to Platinum Holdings and its consolidated subsidiaries, unless the context otherwise indicates. Through December 31, 2006 we also underwrote business through Platinum Re (UK) Limited ("Platinum UK"), our other licensed reinsurance subsidiary. In 2007, Platinum UK ceased underwriting reinsurance business. We provide property and marine, casualty and finite risk reinsurance coverages, through reinsurance intermediaries, to a diverse clientele of insurers and select reinsurers on a worldwide basis.

The condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States ("U.S. GAAP") and include the accounts of Platinum Holdings and its consolidated subsidiaries, including Platinum Bermuda, Platinum US, Platinum UK, Platinum Underwriters Finance, Inc. ("Platinum Finance"), Platinum Regency Holdings ("Platinum Regency"), Platinum Administrative Services, Inc. and Platinum UK Services Company Limited. All material inter-company transactions have been eliminated in preparing these condensed consolidated financial statements. The condensed consolidated financial statements included in this report as of and for the three months ended March 31, 2008 and 2007 are unaudited and include adjustments consisting of normal recurring items that management considers necessary for a fair presentation under U.S. GAAP. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2007.

The preparation of financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could materially differ from these estimates. The results of operations for any interim period are not necessarily indicative of results for the full year.

Recently Effective Accounting Standards

In February 2007, the Financial Accounting Standards Board (the "FASB") issued Statement of Financial Accounting Standards No. 159, "The Fair Value Option for Financial Assets and Financial Liabilities" ("SFAS 159"). SFAS 159 permits an entity to irrevocably elect fair value on a contract-by-contract basis as the initial and subsequent measurement attribute for many financial assets and liabilities and certain other items. Most provisions of SFAS 159 are elective. Entities electing the fair value measurement attributes of SFAS 159 are required to recognize changes in fair values in earnings and to expense upfront costs and fees associated with the items for which the fair values option is elected. SFAS 159 is effective for fiscal years beginning after November 15, 2007. We have not applied the fair value measurement attributes of SFAS 159 to any financial assets or liabilities, and therefore our adoption of SFAS 159 as of January 1, 2008 did not have an effect on our financial condition or results of operations.

In March 2008, the FASB issued Statement of Financial Accounting Standards No. 161, "Disclosure about Derivative Instruments and Hedging Activities – an amendment of FASB Statement No. 133" ("SFAS 161"). SFAS 161 amends and expands the disclosure requirements in SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities” about an entity’s derivative and hedging activities and how these activities affect an entity’s financial position, financial performance and cash flows, thereby improving the transparency of financial reporting. SFAS 161 is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008, with early application encouraged. We are currently evaluating the impact that SFAS 161 may have, if any, on our consolidated financial statements.

2. Investments

Investments classified as available-for-sale are carried at fair value as of the balance sheet date. Net changes in unrealized investment gains and losses on available-for-sale securities, net of deferred taxes, for the three months ended March 31, 2008 and 2007 were as follows ($ in thousands):

	2008			2007
Net change in fair value	$	(1,501	)	$	10,808
Deferred taxes		(2,620	)		(1,379	)
Net change in unrealized investment gains and losses	$	(4,121	)	$	9,429

Gross unrealized gains and losses on available-for-sale securities as of March 31, 2008 were $34,987,000 and $62,179,000, respectively. As of March 31, 2008 there were a total of 267 issues in an unrealized loss position in our investment portfolio, with the single largest unrealized loss being an asset-backed security with an unrealized loss of $4,210,000. Corporate, mortgage-backed and asset-backed securities represent the largest categories within our available-for-sale portfolio and consequently accounted for the greatest amount of our overall unrealized loss as of March 31, 2008. Investment holdings within our corporate portfolio were diversified across approximately 30 industry sectors, ranging from aerospace to telecommunications, and within each sector across many individual issuers and issues. As of March 31, 2008 there were 104 corporate issues in an unrealized loss position, with the single largest unrealized loss being $996,000. Investment holdings within the mortgage-backed and asset-backed portfolio were diversified across a number of sub-categories. As of March 31, 2008 there were 142 issues within the mortgage-backed and asset-backed portfolio in an unrealized loss position.

The unrealized losses on securities classified as available-for-sale, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position as of March 31, 2008, were as follows ($ in thousands):

	Fair Value		Unrealized Loss

Less than twelve months:
U.S. Government	$	–	$	–
Corporate bonds		207,474		5,861
Mortgage-backed and asset-backed securities		424,815		20,661
Municipal bonds		44,785		587
Foreign governments and states		3,013		2
Preferred stocks		970		30
Total	$	681,057	$	27,141

Twelve months or more:
U.S. Government	$	2,659	$	9
Corporate bonds		164,689		12,589
Mortgage-backed and asset-backed securities		271,698		19,903
Municipal bonds		8,179		387
Foreign governments and states		–		–
Preferred stocks		9,096		2,150
Total	$	456,321	$	35,038

Total unrealized losses:
U.S. Government	$	2,659	$	9
Corporate bonds		372,163		18,450
Mortgage-backed and asset-backed securities		696,513		40,564
Municipal bonds		52,964		974
Foreign governments and states		3,013		2
Preferred stocks		10,066		2,180
Total	$	1,137,378	$	62,179

We routinely review our available-for-sale investments to determine whether unrealized losses represent temporary changes in fair value or were the result of "other-than-temporary impairments." The process of determining whether a security is other than temporarily impaired is subjective and involves analyzing many factors. These factors include, but are not limited to: the overall financial condition of the issuer, the length and magnitude of an unrealized loss, specific credit events, the collateral structure and the credit support that may be applicable to mortgage-backed and asset-backed securities. We also consider our ability and intent to hold a security for a sufficient period of time for the value to recover the unrealized loss, which is based, in part, on current and anticipated future positive net cash flows from operations that generate sufficient liquidity in order to meet our obligations. If we determine that an unrealized loss on a security is other than temporary, we write down the carrying value of the security and record a realized loss in the consolidated statement of operations.

Fair Value Measurements

We adopted SFAS No. 157, “Fair Value Measurements” ("SFAS 157") as of January 1, 2008. SFAS 157 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. This statement establishes a framework for measuring fair value and expands disclosures regarding fair value measurements in accordance with U.S. GAAP. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to fair values derived from unobservable inputs (Level 3). The level in the fair value hierarchy within which the fair value measurement in its entirety falls shall be determined based on the lowest level input that is significant to the fair value measurement in its entirety.

We utilize established independent pricing services in valuing our portfolio of fixed maturities and preferred stocks. We consider prices for actively traded treasury securities and exchange traded preferred stocks to be based on quoted prices in active markets for identical assets (Level 1 as defined by SFAS 157). The values of our other fixed maturities, which generally include mortgage-backed and asset-backed securities, corporate bonds, municipal bonds, U.S. government-sponsored enterprises, foreign governments and states, are priced by independent pricing vendors, index providers, or broker-dealers who derive fair values for those assets from observable inputs (Level 2 as defined by SFAS 157). The observable inputs used in standard market valuation pricing models may include but are not limited to: credit ratings, interest rates and yield curves at commonly quoted intervals, volatilities, prepayment speeds, loss severities, credit risks and default rates. Our derivative instruments, which are included in other assets in the consolidated balance sheet, are priced at fair value using unobservable inputs through the application of our own assumptions and internal valuation pricing models (Level 3 as defined by SFAS 157).

- 6 - -

The following table presents the fair value measurement levels for all assets and liabilities which the Company has recorded at fair value as of March 31, 2008 ($ in thousands):

			Fair Value Measurement at Reporting Date Using:

4. Operating Segment Information

We conduct our worldwide reinsurance business through three operating segments: Property and Marine, Casualty and Finite Risk. The Property and Marine operating segment includes principally property and marine reinsurance coverages that are written in the United States and international markets, including property reinsurance, crop reinsurance and marine and aviation reinsurance. The Property and Marine operating segment includes reinsurance contracts that are either catastrophe excess-of-loss, per-risk excess-of-loss or proportional contracts. The Casualty operating segment includes principally reinsurance contracts that cover umbrella liability, general and product liability, professional liability, workers' compensation, casualty clash, automobile liability, surety, trade credit, political risk and accident and health. The Finite Risk operating segment includes principally structured reinsurance contracts with ceding companies whose needs may not be met efficiently through traditional reinsurance products. In exchange for contractual features that limit our downside risk, reinsurance contracts that we classify as finite risk provide the potential for significant profit commission to the ceding company. The classes of risks underwritten through finite risk contracts are generally consistent with the classes covered by traditional products. The finite risk contracts that we underwrite generally provide prospective protection, meaning coverage is provided for losses that are incurred after inception of the contract, as contrasted with retrospective coverage, which covers losses that are incurred prior to inception of the contract. The three main categories of finite risk contracts are quota share, multi-year excess-of-loss and whole account aggregate stop loss.

- 7 - -

In managing our operating segments, we use measures such as underwriting income and underwriting ratios to evaluate segment performance. We do not allocate by segment our assets or certain income and expenses such as investment income, interest expense and certain corporate expenses. Total underwriting income is reconciled to income before income tax expense. The measures we use in evaluating our operating segments should not be used as a substitute for measures determined under U.S. GAAP. The following table summarizes underwriting activity and ratios for the operating segments, together with a reconciliation of total underwriting income to income before income tax expense, for the three months ended March 31, 2008 and 2007 ($ in thousands):

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Business Overview

Platinum Underwriters Holdings, Ltd. ("Platinum Holdings") is a Bermuda holding company organized in 2002. Platinum Holdings and its subsidiaries (collectively, the "Company") operate through two licensed reinsurance subsidiaries: Platinum Underwriters Bermuda, Ltd. ("Platinum Bermuda") and Platinum Underwriters Reinsurance, Inc. ("Platinum US"). The terms "we", "us", and "our" also refer to Platinum Holdings and its consolidated subsidiaries, unless the context otherwise indicates. We provide property and marine, casualty and finite risk reinsurance coverages, through reinsurance intermediaries, to a diverse clientele of insurers and select reinsurers on a worldwide basis. Through December 31, 2006, we also underwrote business through Platinum Re (UK) Limited ("Platinum UK"). In 2007 Platinum UK ceased underwriting reinsurance business.

The following discussion and analysis should be read in conjunction with the consolidated financial statements and related notes thereto and management's discussion and analysis of financial condition and results of operations included in our Annual Report on Form 10-K for the year ended December 31, 2007. Our condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP").

We write property and casualty reinsurance. Property reinsurance protects a ceding company against financial loss arising out of damage to the insured’s property or loss of its use caused by an insured peril. Property reinsurance covers damage principally to buildings and their contents and may be in the form of catastrophe coverage or per-risk coverage. Catastrophe reinsurance coverage protects a ceding company against losses arising out of multiple claims for a single event, while per-risk reinsurance coverage protects a ceding company against loss arising out of a single claim for a single risk or policy. We also write marine reinsurance which protects a ceding company against financial loss arising out of damage to ships and cargo. Casualty reinsurance protects a ceding company against financial loss arising out of the insured’s obligation to others for loss or damage to their persons or property. Examples of casualty coverages are umbrella liability, general and product liability, professional liability, workers' compensation, casualty clash, automobile liability, surety, trade credit, political risk and accident and health. Casualty reinsurance may also be in the form of catastrophe and per-risk contracts.

The property and casualty reinsurance industry is highly competitive. We compete with reinsurers worldwide, many of which have greater financial, marketing and management resources than we do. Our competitors vary by type of business. Large multi-national and multi-line reinsurers represent some of our competitors in all lines and classes, while specialty reinsurance companies in the United States compete in selective lines. Bermuda-based reinsurers tend to be significant competitors on property catastrophe business. Lloyd’s of London syndicates are our significant competitors on marine business. For casualty and other international classes of business, the large U.S. and European reinsurers are our significant competitors. Financial institutions have also created alternative capital market products that compete with reinsurance products, such as reinsurance securitization.

The reinsurance industry historically has been cyclical, characterized by periods of price competition due to excessive underwriting capacity as well as periods of favorable pricing due to shortages of underwriting capacity. Cyclical trends in the industry and the industry's profitability can also be significantly affected by volatile developments, including natural and other catastrophes, such as hurricanes, windstorms, earthquakes, floods, fires, explosions and terrorist attacks, the frequency and severity of which are inherently difficult to predict. Property and casualty reinsurance rates often rise in the aftermath of significant catastrophe losses. To the extent that actual claim liabilities are higher than anticipated, the industry's capacity to write new business diminishes. The industry is also affected by changes in the propensity of courts to expand insurance coverage and grant large liability awards, as well as fluctuations in interest rates, inflation and other changes in the economic environment that affect market prices of investments.

Results of Operations

Net income for the three months ended March 31, 2008 and 2007 was as follows ($ in thousands):

		2008				2007				Increase
Net income		$	105,171				72,833			$	32,338

The increase in net income in 2008 as compared with 2007 was primarily due to an increase in underwriting income of $28,369,000. The increase in underwriting income was due to an increase in net favorable development and a decrease in major catastrophe losses. Actual reported losses were significantly less than expected and gained sufficient credibility in the current period to reduce estimated ultimate losses. Net favorable development was $29,455,000 and $13,895,000 in 2008 and 2007, respectively. The estimated net adverse impact in 2007 from European storm Kyrill was $20,000,000 as compared to a net adverse impact of $6,500,000 from European storm Emma in 2008.

Gross, ceded and net premiums written and earned for the three months ended March 31, 2008 and 2007 were as follows ($ in thousands):

	2008		2007		Increase (decrease)
Gross premiums written	$	300,354		303,135	$	(2,781	)
Ceded premiums written		4,083		4,218		( 135	)
Net premiums written		296,271		298,917		(2,646	)

Gross premiums earned		306,875		292,023		14,852
Ceded premiums earned		5,024		7,175		(2,151	)
Net premiums earned	$	301,851		284,848	$	17,003

The decrease in gross premiums written in 2008 as compared with 2007 was primarily attributable to decreases in gross premiums written across most classes in the Casualty segment, substantially offset by an increase in property gross written premiums. Also impacting 2008 were increases in estimates of net premiums written of $16,478,000 and net premiums earned of $17,305,000 that related to business written in prior underwriting years and resulted from changes in their estimated patterns of attachment. The increase in net premiums earned was also due to changes in the mix of business and the structure of the underlying contracts.

Net investment income for the three months ended March 31, 2008 and 2007 was $49,062,000 and $51,699,000, respectively. Net investment income decreased in 2008 as compared with 2007 primarily due to a decrease in yields on invested assets as well as a slight decrease in invested assets. Net investment income included interest earned on funds held of $837,000 and $1,705,000 in 2008 and 2007, respectively. Net realized gains (losses) on investments were $45,000 and ($18,000) in 2008 and 2007, respectively. Net realized gains and losses on investments primarily resulted from our efforts to manage credit quality and cash flows.

Other income (expense) for the three months ended March 31, 2008 and 2007 was $2,021,000 and ($780,000), respectively. Other income in 2008 included $2,927,000 of net unrealized gains relating to changes in fair value of fixed maturity securities classified as trading, an expense of $810,000 for the fair value adjustment of derivative contracts, and $73,000 of net expense on reinsurance contracts accounted for as deposits. Other expense in 2007 included $665,000 of net unrealized losses relating to changes in the fair value of fixed maturity securities classified as trading and $115,000 of net expense relating to reinsurance contracts accounted for as deposits.

Net losses and loss adjustment expenses ("LAE") and the resulting net loss and LAE ratios for the three months ended March 31, 2008 and 2007 were as follows ($ in thousands):

	2008			2007			Decrease
Net losses and LAE	$	160,203			181,913		$	(21,710	)
Net loss and LAE ratios		53.1	%		63.9	%	(10.8) points

Net acquisition expenses and resulting net acquisition expense ratios for the three months ended March 31, 2008 and 2007 were as follows ($ in thousands):

	2008			2007			Increase
Net acquisition expenses	$	60,542			48,120		$	12,422
Net acquisition expense ratios		20.1	%		16.9	%	3.2 points

The increase in net acquisition expenses in 2008 as compared with 2007 was due to the increase in the net acquisition expense ratio and the increase in net premiums earned. The increase in the net acquisition expense ratio in 2008 as compared with 2007 was primarily due to changes in the mix of business primarily within the Casualty segment towards contracts with higher acquisition cost ratios.

Operating expenses for the three months ended March 31, 2008 and 2007 were $21,690,000 and $23,206,000, respectively. Operating expenses included costs such as salaries, rent and like items related to reinsurance operations as well as costs associated with Platinum Holdings and its non-operating intermediate holding company subsidiaries. The decrease in 2008 as compared with 2007 was primarily due to the expiration on September 30, 2007 of the Services and Capacity Reservation Agreement with Renaissance Re Holdings Ltd. (“RenaissanceRe”) effective October 1, 2002 (the "RenRe Agreement") pursuant to which RenaissanceRe provided consulting services to us in connection with our property catastrophe book of business. In 2007 we incurred fees of $2,880,000 under the RenRe Agreement.

Net foreign currency exchange gains for the three months ended March 31, 2008 and 2007 were $4,869,000 and $42,000, respectively. Foreign currency exchange gains and losses result from the re-valuation into U.S. dollars of assets and liabilities denominated in currencies other than the U.S. dollar. We periodically monitor our foreign currency exposures and may purchase or sell foreign currency denominated assets based on these exposures. The net foreign currency exchange gain in 2008 was the result of our holding more non-U.S. dollar denominated assets than non-U.S. dollar denominated liabilities, primarily the Euro, in the normal course of doing business in these currencies, while the U.S. dollar declined in value against these currencies.

Interest expense for the three months ended March 31, 2008 and 2007 was $4,750,000 and $5,455,000, respectively. The decrease in interest expense was the result of a reduction in the debt obligations outstanding in 2008 as compared to 2007.

Income tax expense and the effective income tax rates for the three months ended March 31, 2008 and 2007 were as follows ($ in thousands):

	2008			2007			Increase (decrease)
Income tax expense	$	5,492			4,264		$	1,228
Effective income tax rates		5.0	%		5.5	%	(0.5) points

The increase in income tax expense in 2008 as compared with 2007 was due to the increase in taxable income generated by our subsidiaries that operate in taxable jurisdictions. The decrease in the effective income tax rate was the result of a greater portion of income before income tax expense being generated by Platinum Holdings and Platinum Bermuda in 2008, which are not subject to corporate income tax. In 2008, the combined net income before income tax expense derived from Platinum Holdings and Platinum Bermuda was 84.0% as compared to 81.2% in 2007. The effective tax rate in any given period is based on income before income tax expense of our subsidiaries that operate in various taxable jurisdictions, each of which has its own corporate income tax rate.

Segment Information

We conduct our worldwide reinsurance business through three operating segments: Property and Marine, Casualty and Finite Risk. In managing our operating segments, we use measures such as underwriting income and underwriting ratios to evaluate segment performance. We do not allocate by segment our assets or certain income and expenses such as investment income, interest expense and certain corporate expenses. Total underwriting income is reconciled to income before income tax expense. The measures we use in evaluating our operating segments should not be used as a substitute for measures determined under U.S. GAAP. The following table summarizes underwriting activity and ratios for each of the three operating segments for the three months ended March 31, 2008 and 2007 ($ in thousands):

	Property and Marine			Casualty			Finite Risk			Total

Property and Marine

The Property and Marine operating segment includes principally property (including crop) and marine reinsurance coverages that are written in the United States and international markets. This business includes property catastrophe excess-of-loss contracts, property per-risk excess-of-loss contracts and property proportional contracts. This operating segment represented 57.0% and 46.1% of our net premiums written during the three months ended March 31, 2008 and 2007, respectively.

Gross, ceded and net premiums written and earned for the three months ended March 31, 2008 and 2007 were as follows ($ in thousands):

	2008		2007		Increase (decrease)
Gross premiums written	$	172,900		143,791	$	29,109
Ceded premiums written		4,083		6,137		(2,054	)
Net premiums written		168,817		137,654		31,163

Gross premiums earned		158,414		128,817		29,597
Ceded premiums earned		5,024		9,107		(4,083	)
Net premiums earned	$	153,390		119,710	$	33,680

The increase in gross premiums written in 2008 as compared to 2007 was primarily due to an increase in North American crop business. In addition there was an increase in reinstatement premiums in the ocean marine class associated with large loss activity. The decline in ceded premiums written was attributable to the non-renewal in 2007 of a quota share retrocessional agreement under which we ceded 30% of our property catastrophe business. Net premiums earned in 2008 increased primarily as a result of the increase in gross premiums written. Net premiums written and earned in 2008 also included increases in estimates of net premiums written of $4,663,000 and net premiums earned of $3,892,000 that related to business written in prior underwriting years, and changes in their estimated patterns of attachment.

Net losses and LAE and the resulting net loss and LAE ratios for the three months ended March 31, 2008 and 2007 were as follows ($ in thousands):

	2008			2007			Decrease
Net losses and LAE	$	62,039			62,627		$	588
Net loss and LAE ratios		40.4	%		52.3	%	11.9 points

The decrease in net losses and LAE and the related ratios in 2008 as compared to 2007 were due to a decrease in major catastrophe losses and an increase in net favorable loss development. European storm Kyrill resulted in $24,520,000 of losses in 2007, which increased the net loss and LAE ratio by 21.3 points, compared to $6,500,000 of losses from European storm Emma in 2008, which increased the net loss and LAE ratio by 4.2 points. Net losses and LAE and the resulting net loss and LAE ratios were also impacted by net favorable loss development of $15,231,000 in 2008, which decreased the net loss and LAE ratio by 10.3 points, and $8,195,000 in 2007, which decreased the net loss and LAE ratio by 6.8 points. Exclusive of losses resulting from European storms Kyrill and Emma and net favorable development, the net loss and LAE ratio increased by approximately 8.0 points due primarily to an increase in crop quota share business that has a higher expected loss ratio than the remainder of the segment. In addition, expected loss ratios for the 2008 underwriting year for most classes were higher than for the 2007 underwriting year due to decreasing rates. The net loss and LAE ratios were also affected by other changes in the mix of business.

Net acquisition expenses and resulting net acquisition expense ratios for the three months ended March 31, 2008 and 2007 were as follows ($ in thousands):

	2008			2007			Increase
Net acquisition expenses	$	20,654			15,935		$	4,719
Net acquisition expense ratios		13.5	%		13.3	%	0.2 points

The increase in net acquisition expenses in 2008 as compared with 2007 was primarily due to an increase in net premiums earned. The net acquisition expense ratios were comparable.

Other underwriting expenses in 2008 and 2007 were $8,596,000 and $10,028,000, respectively. The decrease in 2008 as compared with 2007 was primarily due to the expiration of the RenRe Agreement on September 30, 2007. We incurred fees of $2,880,000 under the RenRe Agreement in 2007.

Casualty

The Casualty operating segment includes principally reinsurance contracts that cover umbrella liability, general and product liability, professional liability, workers' compensation, casualty clash, automobile liability, surety, trade credit, political risk and accident and health. This operating segment represented 42.4% and 50.9% of our net premiums written during the three months ended March 31, 2008 and 2007, respectively.

Gross, ceded and net premiums written and earned for the three months ended March 31, 2008 and 2007 were as follows ($ in thousands):

	2008		2007		Decrease
Gross premiums written	$	125,576		152,206	$	26,630
Ceded premiums written		–		23		23
Net premiums written		125,576		152,183		26,607

Gross premiums earned		147,495		154,029		6,534
Ceded premiums earned		–		10		10
Net premiums earned	$	147,495		154,019	$	6,524

The decrease in net premiums written in 2008 as compared with 2007 was primarily due to decreases in business underwritten in 2007 and 2008 across most North American casualty classes with the most significant decreases in the umbrella class. The decrease was the result of fewer opportunities that met our underwriting standards. Also impacting premiums written and earned were changes in estimates in prior underwriting years’ ultimate premiums and the patterns of their attachment resulting in increases in 2008 of net premiums written of $11,792,000 and net premiums earned of $13,390,000. Net premiums written and earned were also affected by changes in the mix of business and the structure of the underlying reinsurance contracts.

Net losses and LAE and the resulting net loss and LAE ratios for the three months ended March 31, 2008 and 2007 were as follows ($ in thousands):

	2008			2007			Decrease
Net losses and LAE	$	99,393			112,382		$	12,989
Net loss and LAE ratios		67.4	%		73.0	%	5.6 points

The decrease in net losses and LAE and the related ratios in 2008 as compared with 2007 were primarily due to the decrease in net premiums earned and an increase in net favorable loss development. Net favorable loss development was $12,088,000 in 2008, which decreased the net loss and LAE ratio by 8.2 points, as compared with $1,397,000 in 2007, which decreased the net loss and LAE ratio by 0.9 points. Excluding the impact of net favorable loss development, the net loss and LAE ratio increased by 0.8 points in 2008 as compared with 2007 due to higher initial expected loss ratios in certain significant classes reflecting a decline in price adequacy. The net loss and LAE ratio in 2008 was also affected by the changes in the mix of business.

Net acquisition expenses and resulting net acquisition expense ratios for the three months ended March 31, 2008 and 2007 were as follows ($ in thousands):

	2008			2007			Increase
Net acquisition expenses	$	37,488			32,035		$	5,453
Net acquisition expense ratios		25.4	%		20.8	%	4.6 points

The increase in net acquisition expenses in 2008 as compared with 2007 was due to differences in changes to adjustable commission. Net acquisition expenses included an increase in adjustable commissions of $3,418,000 in 2008 related to favorable net loss development from prior years, representing 2.5% of net premiums earned as compared with a decrease of $2,190,000 in 2007, representing 1.4% of net premiums earned. Net acquisition expense ratios were also impacted by changes in the mix of business.

Other underwriting expenses were comparable at $6,795,000 and $6,717,000 for the three months ended March 31, 2008 and 2007, respectively.

Finite Risk

The Finite Risk operating segment includes principally structured reinsurance contracts with ceding companies whose needs may not be met efficiently through traditional reinsurance products. In exchange for contractual features that limit our downside risk, reinsurance contracts that we classify as finite risk provide the potential for significant profit commission to the ceding company. The classes of risks underwritten through finite risk contracts are generally consistent with the classes covered by traditional products. The finite risk contracts that we underwrite generally provide prospective protection, meaning coverage is provided for losses that are incurred after inception of the contract, as contrasted with retrospective coverage, which covers losses that are incurred prior to inception of the contract. The three main categories of our finite risk contracts are quota share, multi-year excess-of-loss and whole account aggregate stop loss. Due to the often significant inverse relationship between losses and commissions for this segment, we believe it is important to evaluate the overall combined ratio, rather than its component parts of net loss and LAE ratio and net acquisition expense ratio. The industry-wide investigations by governmental and regulatory authorities into potential misuse of finite products curtailed demand for these products beginning in 2005. This diminished demand continues in 2008. This operating segment represented 0.6% and 3.0% of our net premiums written during the three months ended March 31, 2008 and 2007, respectively.

Gross, ceded and net premiums written and earned for the three months ended March 31, 2008 and 2007 were as follows ($ in thousands):

	2008		2007			Increase (decrease)
Gross premiums written	$	1,878		7,138		$	(5,260	)
Ceded premiums written		–		(1,942	)		1,942
Net premiums written		1,878		9,080			(7,202	)

Gross premiums earned		966		9,177			(8,211	)
Ceded premiums earned		–		(1,942	)		1,942
Net premiums earned	$	966		11,119		$	(10,153	)

The decreases in net premiums written and net premiums earned in 2008 as compared with 2007 reflect the continuing reduction in the demand for finite business.

Net losses and LAE, net acquisition expenses and the resulting net loss and LAE and acquisition ratios for the three months ended March 31, 2008 and 2007 were as follows ($ in thousands):

	2008			2007			Increase (decrease)
Net losses and LAE	$	(1,229	)		6,904		$	(8,133	)
Net acquisition expenses		2,400			150			2,250
Net losses, LAE and acquisition expenses	$	1,171			7,054		$	(5,883	)
Net loss, LAE and acquisition expense ratios		121.2	%		63.4	%	57.8 points

The decrease in net losses, LAE and acquisition expenses in 2008 as compared with 2007 was primarily due to the decrease in net premiums earned. The increase in the net loss, LAE and acquisition expense ratio was primarily due to an increase in profit commission from prior years. Net unfavorable development was $213,000 in 2008, which increased the net loss and LAE ratio by 22.0 points, as compared with net favorable development of approximately $2,688,000 in 2007, which decreased the net loss and LAE ratio by 24.2 points. Also contributing to the increase in the net loss, LAE and acquisition expense ratio in 2008 was the expiration of a significant finite casualty contract that had a lower combined ratio than the remainder of the Finite Risk segment.

Other underwriting expenses for the three months ended March 31, 2008 and 2007 were $310,000 and $1,034,000, respectively. The decrease in 2008 as compared with 2007 was due to a decline in underwriting activity in the segment and a lower percentage of underwriting expenses allocated to the segment.

Financial Condition, Liquidity and Capital Resources

Financial Condition

Cash and cash equivalents and investments as of March 31, 2008 and December 31, 2007 were as follows ($ in thousands):

	March 31, 2008		December 31, 2007		Increase (decrease)
Cash and cash equivalents	$	1,034,344		1,076,279	$	(41,935	)
Fixed maturity securities		3,205,200		3,361,741		(156,541	)
Preferred stocks		10,066		9,607		459
Short-term investments		135,418		13,876		121,542
Total	$	4,385,028		4,461,503	$	(76,475	)

The net decrease in total cash and cash equivalents and investments as of March 31, 2008 as compared with December 31, 2007 was primarily due to our share repurchases in 2008. Our available-for-sale and trading portfolios are primarily composed of diversified, high quality, predominantly publicly traded fixed maturity securities. The investment portfolio, excluding cash and cash equivalents, had a weighted average duration of 3.1 years as of March 31, 2008. We routinely monitor the composition of our investment portfolio and cash flows in order to maintain liquidity necessary to meet our obligations.

- 17 - -

As of March 31, 2008, we had $1,403,483,000 of mortgage-backed and asset-backed securities in our investment portfolio, representing approximately 32% of cash and cash equivalents and investments. The following is a breakdown of our mortgage-backed and asset-backed securities as of March 31, 2008 ($ amounts in thousands):

	Amortized Cost		Fair Value		Weighted Average Credit Rating
U.S. Government agency mortgage-backed securities	$	638,388	$	646,273	Aaa
Commercial mortgage-backed securities		394,029		377,900	Aaa
Asset-backed securities		203,789		194,837	Aaa
Residential mortgage-backed securities		195,866		184,473	Aa
Total	$	1,432,072	$	1,403,483	Aaa

Approximately 46% of the mortgage-backed and asset-backed securities in our investment portfolio were issued or guaranteed by the Government National Mortgage Association, the Federal National Mortgage Association, or the Federal Home Loan Mortgage Corporation and are referred to as U.S. Government agency mortgage-backed securities. Included in residential mortgage-backed securities were securities with an amortized cost of $22,290,000 and fair value of $20,865,000 where the underlying collateral consists primarily of “Alt-A” mortgages. These securities have a weighted average credit rating of Aa at March 31, 2008.

The U.S. sub-prime residential mortgage market has experienced significantly increased delinquencies which resulted in increased volatility and decreased liquidity in the financial markets and the structured securities markets in particular. Our securities with underlying sub-prime mortgage exposure were categorized above as asset-backed securities and were investment grade at March 31, 2008. The following table summarizes our nine asset-backed securities within our fixed income portfolio exposed to the sub-prime residential mortgage market as of March 31, 2008 ($ in thousands):

	Amortized Cost		Fair Value
Vintage year 2005 and ratings of Aa or A	$	38,136	$	28,133
Vintage year 2006 and ratings of Aaa		3,994		2,860
Total	$	42,130	$	30,993

We continually monitor market events impacting our portfolio, including our sub-prime securities, and review sub-prime securities along with the rest of our portfolio for potential other-than-temporary impairments. We did not consider any of the mortgage-backed and asset-backed securities we hold to be other-than-temporarily impaired as of March 31, 2008.

Certain assets and liabilities associated with underwriting include significant estimates. Reinsurance premiums receivable, deferred acquisition costs, unpaid losses and LAE, unearned premiums and commissions payable all represent or include significant estimates. Reinsurance premiums receivable as of March 31, 2008 of $304,240,000 included $238,789,000 that was based upon estimates. Reinsurance premiums receivable as of December 31, 2007 of $244,360,000 included $195,890,000 that was based upon estimates. The increase in reinsurance premiums receivable as of March 31, 2008 as compared with December 31, 2007 was due to an increase in the premiums written in the first quarter of 2008 as compared to the fourth quarter of 2007. An allowance for uncollectible reinsurance premiums is considered for possible non-payment of such amounts due, as deemed necessary. As of March 31, 2008, based on our historical experience, the general profile of our ceding companies and our ability, in most cases, to contractually offset reinsurance premiums receivable with losses and LAE or other amounts payable to the same parties, we did not establish an allowance for uncollectible reinsurance premiums receivable.

Gross unpaid losses and LAE as of March 31, 2008 of $2,410,227,000 included $1,735,751,000 of estimates of claims that are incurred but not reported ("IBNR"). Gross unpaid losses and LAE as of December 31, 2007 of $2,361,038,000 included $1,700,454,000 of IBNR. The increase in unpaid losses related primarily to the casualty line of business as minor increases in the property and marine business were offset by declines in unpaid losses related to finite business.

Commissions payable as of March 31, 2008 of $111,908,000 included $92,234,000 that was based upon premium estimates. Commissions payable as of December 31, 2007 of $100,204,000 included $91,035,000 that was based upon premium estimates. The increase in commissions payable as of March 31, 2008 as compared with December 31, 2007 was due to the increase in premiums written in the first quarter of 2008 as compared to the fourth quarter of 2007 and is consistent with the increase in reinsurance premiums receivable.

We entered into two derivative contracts during the first quarter of 2008. The first was an option to purchase retrocessional protection. The second was a derivative contract under which we can recover up to $120,000,000 from the counterparty if modeled losses from both a first and second catastrophe event exceed a specified attachment point. The fair values of these derivatives were adjusted and the resulting expense of $810,000 was included in other expense in 2008.

Sources of Liquidity

Our consolidated sources of funds consist primarily of premiums written, investment income, proceeds from sales and redemption of investments, losses recovered from retrocessionaires, issuance of securities and actual cash and cash equivalents held by us. Net cash flows provided by operations, excluding trading security activities, for the three months ended March 31, 2008 were $97,280,000.

Platinum Holdings is a holding company that conducts no reinsurance operations of its own. All of our reinsurance operations are conducted through our wholly owned reinsurance subsidiaries, Platinum Bermuda and Platinum US. As a holding company, the cash flows of Platinum Holdings consist primarily of interest income, dividends and other permissible payments from its subsidiaries and issuances of securities. Platinum Holdings depends on such payments for general corporate purposes and to meet its obligations, including the payment of preferred dividends, common dividends and repurchases of common shares.

In addition to the net cash flows generated from operations, we have an effective universal shelf registration statement whereby we may issue and sell, in one or more offerings, up to $750,000,000 of debt, equity and other types of securities or a combination of such securities, including debt securities of Platinum Finance unconditionally guaranteed by Platinum Holdings. This shelf registration statement had approximately $440,000,000 of remaining capacity as of March 31, 2008. We also have a $400,000,000 credit facility with a syndicate of lenders available for revolving borrowings and letters of credit expiring on September 13, 2011. The credit facility is generally available for our working capital, liquidity, letters of credit and general corporate requirements and those of our subsidiaries. As of March 31, 2008 this facility had $317,992,000 of capacity available to us.

Our principal consolidated cash requirements are the payment of losses and LAE, commissions, brokerage, operating expenses, dividends to our preferred and common shareholders, the servicing of debt, capital expenditures, purchase of retrocessional contracts and payment of taxes.

Platinum Bermuda is not licensed, approved or accredited as a reinsurer anywhere in the United States and, therefore, under the terms of most of its contracts with United States ceding companies, it is required to provide collateral to its ceding companies for unpaid ceded liabilities in a form acceptable to state insurance commissioners. Typically, this type of collateral takes the form of letters of credit issued by a bank, the establishment of a trust, or funds withheld. Platinum Bermuda provides letters of credit through the credit facility and may be required to provide the banks with a security interest in certain investments of Platinum Bermuda including the credit facility described above.

We believe that the net cash flows generated by the operating activities of our subsidiaries in combination with cash and cash equivalents on hand will provide sufficient funds to meet our liquidity needs over the next twelve months. Beyond the next twelve months, cash flows available to us may be influenced by a variety of factors, including economic conditions in general and in the insurance and reinsurance markets, legal and regulatory changes as well as fluctuations from year to year in claims experience and the occurrence or absence of large catastrophic events. If our liquidity needs accelerate beyond our ability to fund such obligations from current operating cash flows, we may need to liquidate a portion of our investment portfolio, borrow under the credit facility described above or raise additional capital in the capital markets. Our ability to meet our liquidity needs by selling investments or raising additional capital is subject to the timing and pricing risks inherent in the capital markets.

Capital Resources

The Company does not have any material commitments for capital expenditures as of March 31, 2008.

Off-Balance Sheet Arrangements

The Company does not have any off-balance sheet arrangements and, therefore, there is no effect on its financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources from these types of arrangements.

Contractual Obligations

There have been no material changes to our contractual obligations as disclosed under Management’s Discussion and Analysis of Financial Condition – Contractual Obligations in our Annual Report on Form 10-K for the year ended December 31, 2007.

Economic Conditions

Periods of moderate economic recession or inflation tend not to have a significant direct effect on our underwriting operations. Significant unexpected inflationary or recessionary periods can, however, impact our underwriting operations and investment portfolio. Management considers the potential impact of economic trends in the estimation process for establishing unpaid losses and LAE.

Current Outlook

During the period from January 1 through April 1, 2008, approximately 67% of our business was up for renewal. We were able to maintain the size of our net portfolio of reinsurance contracts as new business largely offset cancelled business. While rate adequacy declined in most classes, we found relatively more attractive opportunities in our Property and Marine segment and fewer attractive opportunities in our Casualty and Finite segments.

For the Property and Marine segment, during the period from January 1 through April 1, 2008 we experienced average rate decreases of 12% on our U.S. property catastrophe excess renewal business while rates on our non-U.S. property catastrophe excess renewal business were down 4%. In addition, we experienced average rate decreases of approximately 12% on our marine renewal business. Per risk excess rates decreased approximately 5% for our U.S. business and approximately 3% for our non-U.S. business.

During the period from January 1 through April 1, 2008 we increased our writings of North American crop business from approximately $47 million to approximately $129 million. Most of this increase was attributable to one large quota share contract. While favorable experience in recent years has led to some deterioration in terms and conditions in this class of business, we believe there remains an adequate opportunity for profit. As most of the crop reinsurance contracts incept at January 1 we do not expect to write a significant amount of additional crop business for the remainder of 2008.

During the period from January 1 through April 1, 2008 we wrote approximately 15% less U.S. catastrophe excess-of-loss premium than we did during the same period in 2007. However, due to the rate decreases in this class of business, our net retained risk has remained at the same level for 2008 while our potential profit has decreased. We believe the profitability remains adequate for the risk and for 2008 we plan to deploy capacity such that up to approximately 22.5% of our total capital could be exposed to an event with a probability of 1 in 250 years.

The lack of significant catastrophe activity in 2007 contributed to excellent financial results, stronger balance sheets and increased capacity for many reinsurers. Though many reinsurers have implemented capital management programs, we believe the net effect has been increased industry capacity. This has led to intensified competition and rate decreases in 2008. We believe that most classes within the Property and Marine segment will continue to experience some rate deterioration for the remainder of 2008.

For the Casualty segment, although we believe that the market offers adequate returns on certain accounts, pricing has been softening. Ceding companies are willing to increase retentions and reinsurers are competing for participation on the best contracts. During the period from January 1 though April 1, 2008 rate decreases across our casualty business, other than accident and health, have ranged from approximately 1% to 11%. The overall average was a decrease of approximately 7%, against a background of upward trending loss costs. As a result, we believe the business underwritten in 2008 will have a lower level of expected profitability as compared with the business underwritten in 2007.

- 19 - -

During the period January1 through April 1, 2008 we wrote approximately 18% less casualty business than we did during the same period in 2007. We expect market conditions will continue to weaken through the remainder of 2008 and that fewer casualty opportunities will be attractive. We believe that financial security remains a significant concern for buyers of long-tailed reinsurance protection who typically seek reinsurers with strong balance sheets, quality ratings, and a proven claims-paying record. We believe that our rating, capitalization and reputation as a lead casualty reinsurer position us well to write profitable business as opportunities arise.

In the Finite Risk segment, we believe that the ongoing investigations by the SEC, the office of the Attorney General for the State of New York, the U.S. Attorney for the Southern District of New York as well as various non-U.S. regulatory authorities continue to limit demand for finite risk transfer products. We expect the relatively low level of demand will continue for the foreseeable future.

Critical Accounting Estimates

It is important to understand our accounting estimates in order to understand our financial position and results of operations. We consider certain of these estimates to be critical to the presentation of the financial results since they require management to make estimates and valuation assumptions. These estimates and assumptions affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures. Certain of the estimates and assumptions result from judgments that are necessarily subjective and, consequently, actual results may materially differ from these estimates. Our critical accounting estimates include premiums written and earned, unpaid losses and LAE, valuation of investments and evaluation of risk transfer. For a detailed discussion of the Company’s critical accounting estimates please refer to Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the year ended December 31, 2007. There have been no material changes in the application of the Company’s critical accounting estimates subsequent to December 31, 2007.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market and Credit Risk

During the quarter, the fair values of our fixed maturity securities experienced significant volatility resulting in large changes in our unrealized gain and loss position at any particular point in time due to a combination of economic events. The contagion from the sub-prime residential mortgage market was evident in most other fixed income sectors as illiquidity in the market place continued and interest rate spreads reached historical levels against U.S. treasuries, most notably spreads on mortgage-backed and asset-backed securities. The Federal Reserve in the United States reduced the federal funds target rate by 200 basis points during the first quarter and intervened with non-traditional measures to enhance and promote market liquidity and ensure financial market stability.

Our principal invested assets are fixed maturity securities, which are subject to the risk of potential losses from adverse changes in market rates and prices and credit risk resulting from adverse changes in the borrower's ability to meet its debt service obligations. Our strategy to limit this risk is to place our investments in high quality credit issues and to limit the amount of credit exposure with respect to any one issuer or asset class. We also select investments with characteristics such as duration, yield, currency and liquidity to reflect, in the aggregate, the underlying characteristics of our unpaid losses and LAE. We attempt to minimize the credit risk by actively monitoring the portfolio and establishing a guideline minimum average credit rating for our portfolio of A2 as defined by Moody's Investor Service ("Moody’s"). As of March 31, 2008, the portfolio, excluding cash, cash equivalents and short-term investments, had a dollar weighted average credit rating of Aa1 as defined by Moody’s.

We have other receivable amounts subject to credit risk. The most significant of these are reinsurance premiums receivable from ceding companies. We also have reinsurance recoverable amounts from our retrocessionaires. To mitigate credit risk related to premiums receivable, we have established standards for ceding companies and, in most cases, have a contractual right of offset which would allow us to settle claims net of any premiums receivable. To mitigate credit risk related to our reinsurance recoverable amounts, we consider the financial strength of our retrocessionaires when determining whether to purchase coverage from them. Retrocessional coverage is obtained from companies rated “A-” or better by A. M. Best Company, Inc. ("A.M. Best") or from retrocessionaires whose obligations are fully collateralized. The financial performance and rating status of all material retrocessionaires is routinely monitored.

In accordance with industry practice, we frequently pay amounts in respect of claims under contracts to reinsurance brokers for payment over to the ceding companies. In the event that a broker fails to make such a payment, depending on the jurisdiction, we may remain liable to the ceding company for the payment. Conversely, in certain jurisdictions, when ceding companies remit premiums to reinsurance brokers, such premiums are deemed to have been paid to us and the ceding company is no longer liable to us for those amounts whether or not the funds are actually received by us. Consequently, we assume a degree of credit risk associated with our brokers during the premium and loss settlement process. To mitigate credit risk related to reinsurance brokers, we have established guidelines for brokers and intermediaries.

Interest Rate Risk

We are exposed to fluctuations in interest rates. Movements in rates can result in changes in the market value of our fixed maturity portfolio and can cause changes in the actual timing of receipt of principal payments of certain securities. Rising interest rates result in a decrease in the market value of our fixed maturity portfolio and can expose our portfolio, in particular our mortgage-backed securities, to extension risk. Conversely, a decrease in interest rates will result in an increase in the market value of our fixed maturity portfolio and can expose our portfolio, in particular our mortgage-backed securities, to prepayment risk. An aggregate hypothetical impact on the market value of our fixed maturity portfolio, generated from an immediate parallel shift in the treasury yield curve, as of March 31, 2008 is as follows ($ in thousands):

	Interest Rate Shift in Basis Points
		- 100 bp		- 50 bp		Current		+ 50 bp			+ 100 bp
Total market value	$	3,363,291		3,260,467		3,205,200		3,151,745		$	3,095,661
Percent change in market value		4.9	%	1.7	%			(1.7	%)		(3.4	%)
Resulting unrealized appreciation / (depreciation)	$	134,836		32,012		(23,255	)	(76,710	)	$	(132,794	)

- 20 - -

Foreign Currency Exchange Rate Risk

We write business on a worldwide basis. Consequently, our principal exposure to foreign currency risk is the transaction of business in foreign currencies. Changes in foreign currency exchange rates can impact revenues, costs, receivables and liabilities, as measured in the U.S. dollar, our financial reporting currency. We manage our exposure to large foreign currency risks by holding invested assets denominated in non-U.S. dollar currencies to offset liabilities denominated in the same foreign currencies. We may from time to time hold more non-U.S. dollar denominated assets than non-U.S. dollar liabilities.

Sources of Fair Value

The following table presents the carrying amounts and estimated fair values of our financial instruments as of March 31, 2008 ($ in thousands):

	Carrying Amount		Fair Value
Financial assets:
Fixed maturity securities	$	3,205,200	$	3,205,200
Preferred stocks		10,066		10,066
Short-term investments		135,418		135,418
Derivative instruments		5,950		5,950

Financial liabilities:
Debt obligations	$	250,000	$	249,750

The fair value of our fixed maturity securities, preferred stocks, short-term investments and debt obligations are based on prices obtained from independent sources for those or similar investments using quoted prices in active markets and standard market valuation pricing models. The inputs used in standard market valuation pricing models may include but are not limited to: credit ratings, interest rates and yield curves at commonly quoted intervals, volatilities, prepayment speeds, loss severities, credit risks and default rates. Our derivative instruments, which are included in other assets in the consolidated balance sheet, are priced at fair value using unobservable inputs through the application of our own assumptions and internal valuation pricing models.

Item 4. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

Our management, including the Chief Executive Officer and Chief Financial Officer, carried out an evaluation of the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the "Exchange Act")) as of the end of the period covered by this report. Based on that evaluation, our management, including the Chief Executive Officer and Chief Financial Officer, concluded that our disclosure controls and procedures are effective to provide reasonable assurance that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and timely reported as specified in the SEC’s rules and forms.

Changes in Internal Control over Financial Reporting

No changes occurred during the quarter ended March 31, 2008 in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Forward-Looking Statements

This Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Exchange Act. Forward-looking statements are necessarily based on estimates and assumptions that are inherently subject to significant business, economic and competitive uncertainties and contingencies, many of which are subject to change. These uncertainties and contingencies can affect actual results and could cause actual results to differ materially from those expressed in any forward-looking statements made by, or on behalf of, us.

In particular, statements using words such as “may,” “should,” “estimate,” “expect,” “anticipate,” “intend,” “believe,” “predict,” “potential,” or words of similar import generally involve forward-looking statements. For example, we have included certain forward-looking statements in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” with regard to trends in results, prices, volumes, operations, investment results, margins, risk management and exchange rates. This Form 10-Q also contains forward-looking statements with respect to our business and industry, such as those relating to our strategy and management objectives and trends in market conditions, market standing, product volumes, investment results and pricing conditions.

In light of the risks and uncertainties inherent in all future projections, the inclusion of forward-looking statements in this Form 10-Q should not be considered as a representation by us or any other person that our objectives or plans will be achieved. Numerous factors could cause our actual results to differ materially from those in forward-looking statements, including the following:

(1)

significant weather-related or other natural or man-made disasters over which we have no control;

(2)

the effectiveness of our loss limitation methods and pricing models;

(3)

the adequacy of our liability for unpaid losses and LAE;

(4)

our ability to maintain our A.M. Best. rating;

(5)

the cyclicality of the property and casualty reinsurance business;

(6)

conducting operations in a competitive environment;

- 21 - -

(7)	our ability to maintain our business relationships with reinsurance brokers;

(8)	the availability of retrocessional reinsurance on acceptable terms;

(9)	market volatility, interest rate and currency exchange rate fluctuation, and credit risk on invested assets;

(10)	tax, regulatory or legal restrictions or limitations applicable to us or the property and casualty reinsurance business generally;

(11)	general political and economic conditions, including the effects of civil unrest, acts of terrorism, war or a prolonged U.S. or global economic downturn or recession; and

(12)	changes in our plans, strategies, objectives, expectations or intentions, which may happen at any time at our discretion.

As a consequence, current plans, anticipated actions and future financial condition and results may differ from those expressed in any forward-looking statements made by or on behalf of us. The foregoing factors, which are discussed in more detail in Item 1A – “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2007, should not be construed as exhaustive. Additionally, forward-looking statements speak only as of the date they are made, and we undertake no obligation to release publicly the results of any future revisions or updates we may make to forward-looking statements to reflect new information or circumstances after the date hereof or to reflect the occurrence of future events.
