Platinum Underwriters Holdings, Ltd. and Subsidiaries

Notes to Condensed Consolidated Financial Statements (Unaudited)
For the Three and Six Months Ended June 30, 2006 and 2005

1. Basis of Presentation

     The condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include the accounts of Platinum Underwriters Holdings, Ltd. (“Platinum Holdings”) and its subsidiaries (collectively, the “Company”), including Platinum Underwriters Bermuda, Ltd. (“Platinum Bermuda”), Platinum Underwriters Reinsurance, Inc. (“Platinum US”), Platinum Re (UK) Limited, Platinum Underwriters Finance, Inc. (“Platinum Finance”), Platinum Regency Holdings (“Platinum Regency”), and Platinum Administrative Services, Inc. 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 and six months ended June 30, 2006 and 2005 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 the Company’s Annual Report on Form 10-K for the year ended December 31, 2005.

     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.

Share-Based Compensation

     We adopted Statement of Financial Accounting Standards No. 123R “Share-Based Payment” (“SFAS 123R”) using the modified prospective method effective January 1, 2006. SFAS 123R establishes standards for the accounting for transactions in which an entity exchanges its equity instruments for goods or services. SFAS 123R requires that, prospectively, compensation costs be recognized for the fair value of all share options over their vesting period, including the cost related to the unvested portion of all outstanding share options as of December 31, 2005. The cumulative effect of the adoption of SFAS 123R was not material.

     Prior to January 1, 2006, we accounted for share-based compensation using Statement of Financial Accounting Standards No. 123 “Accounting for Awards of Stock Based Compensation to Employees” and Statement of Financial Accounting Standards No. 148 “Accounting for Stock-Based Compensation-Transition and Disclosure” (“SFAS 148”). In accordance with the transition rules of SFAS 148, we elected to continue using the intrinsic value method of accounting for our share-based awards granted to employees established by Accounting Principles Board Opinion No. 25 “Accounting for Stock Issued to Employees” (“APB 25”) for share options granted in 2002. Under APB 25, if the exercise price of our employee share options is equal to or greater than the fair market value of the underlying shares on the date of the grant, no compensation expense is recorded.

     The following table illustrates the effect on our net income and earnings per share for the three and six months ended June 30, 2005 of applying the “fair value” method to all share option grants ($ in thousands, except per share data):

2. Investments

     Investments classified as available-for-sale are carried at fair value as of the balance sheet date. Net change in unrealized investment gains and losses on available-for-sale securities, net of deferred taxes for the six months ended June 30, 2006 and 2005 were as follows ($ in thousands):

     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 June 30, 2006 were as follows ($ in thousands):

			Unrealized
	Fair Value		Loss
Less than twelve months:
U.S. Government	$	148,599	$	4,410
Corporate bonds		906,290		38,171
Mortgage-backed and asset-backed securities		932,625		36,910
Municipal bonds		121,118		3,296
Foreign governments and states		13,060		706
Total		2,121,692		83,493
Twelve months or more:
U.S. Government		30,413		381
Corporate bonds		483,512		16,691
Mortgage-backed and asset-backed securities		188,068		10,263
Municipal bonds		76,038		1,976
Foreign governments and states		27,113		901
Preferred stocks		7,699		1,035
Total	$	812,843	$	31,247
Total of securities with unrealized losses:
U.S. Government	$	179,012	$	4,791
Corporate bonds		1,389,802		54,862
Mortgage-backed and asset-backed securities		1,120,693		47,173
Municipal bonds		197,156		5,272
Foreign governments and states		40,173		1,607
Preferred stocks		7,699		1,035
Total	$	2,934,535	$	114,740

     We routinely review our available-for-sale investments to determine whether unrealized losses represent temporary changes in fair value or are 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, and 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 statement of operations.

For the Three and Six Months Ended June 30, 2006 and 2005

     Corporate, mortgage-backed and asset-backed securities represent our largest categories within our available-for-sale portfolio and consequently account for the greatest amount of our overall unrealized loss as of June 30, 2006. Investment holdings within our corporate portfolio are diversified across approximately 30 sub-portfolios, ranging from aerospace to telecommunications, and within each sub-portfolio across many individual issuers and issues. As of June 30, 2006 there were 498 corporate issues in an unrealized loss position, with the single largest unrealized loss being $901,000. Investment holdings within the mortgage-backed and asset-backed portfolio are diversified across a number of sub-categories. As of June 30, 2006 there were 318 issues within the mortgage-backed and asset-backed portfolio in an unrealized loss position, with the single largest unrealized loss being $1,356,000. As of June 30, 2006 there were a total of 923 issues in an unrealized loss position in our investment portfolio, with the single largest unrealized loss being $1,356,000.

     Overall our unrealized loss position as of June 30, 2006 was a result of continuing interest rate increases that impacted all investment categories. Given our ability and intent to hold these investments until a recovery of fair value, which may be maturity, we do not consider any of our available-for-sale investments to be other-than-temporarily impaired as of June 30, 2006.

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 (including crop) and marine reinsurance coverages that are written in the United States and international markets. This business includes catastrophe excess-of-loss treaties, per-risk excess-of-loss treaties and proportional treaties. The Casualty operating segment includes principally reinsurance

treaties that cover umbrella liability, general and product liability, professional liability, workers’ compensation, casualty clash, automobile liability, surety and trade credit. This operating segment also includes accident and health treaties, which are predominantly reinsurance of health insurance products. The Finite Risk operating segment includes principally structured reinsurance contracts with ceding companies whose needs may not be met efficiently through traditional reinsurance products. The classes of risks underwritten through finite risk contracts are generally consistent with the classes covered by traditional products. Typically, the amount of losses we might pay is finite or capped. In return for this limit on losses, we often accept a cap on the potential profit margin specified in the treaty and return profits above this margin to the ceding company. 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 finite quota share, multi-year excess-of-loss and whole account aggregate stop loss.

     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 and six months ended June 30, 2006 and 2005 ($ in thousands):

Under this agreement the retrocessionnaire is obligated to place premiums ceded in a trust for the benefit of Platinum US and Platinum UK as well as provide a letter of credit such that the combination of the two amounts will ultimately collateralize the limit of loss under this treaty. As of June 30, 2006, assets with a fair value of $10,535,000 were held in trust and Platinum US holds letters of credit in the amount of $95,760,000.

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

FOR THE THREE AND SIX MONTHS ENDED JUNE 30, 2006 AND 2005

Business Overview

     The Platinum Underwriters Holdings, Ltd. (“Platinum Holdings”) is a Bermuda holding company organized in 2002. Platinum Holdings and its subsidiaries (collectively, the “Company”) operate through three licensed reinsurance subsidiaries: Platinum Underwriters Bermuda, Ltd. (“Platinum Bermuda”), Platinum Underwriters Reinsurance, Inc. (“Platinum US”) and Platinum Re (UK) Limited (“Platinum UK”). The Company provides 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 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, 2005. Our consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”).

     We write property and casualty reinsurance. Property reinsurance protects a ceding company against financial loss arising out of damage to property or loss of its use caused by an insured peril. Examples of property reinsurance are property catastrophe and property per-risk coverages. Property catastrophe reinsurance protects a ceding company against losses arising out of multiple claims for a single event while property per-risk reinsurance protects a ceding company against loss arising out of a single claim for a single event. Casualty reinsurance protects a ceding company against financial loss arising out of the obligation to others for loss or damage to persons or property. Examples of casualty reinsurance are reinsurance treaties that cover umbrella liability, general and product liability, professional liability, workers’ compensation, casualty clash, automobile liability, surety and trade credit. Casualty reinsurance also includes accident and health reinsurance treaties, which are predominantly reinsurance of health insurance products.

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

     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

- 23 -

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.

     Both insurers and reinsurers experienced record losses in 2005 from three significant named hurricanes, Katrina, Rita and Wilma (the “2005 Hurricanes”). These record catastrophe losses placed a significant strain on the capital of a number of companies. Commercial catastrophe models use more severe assumptions for frequency and severity of hurricane losses, rating agencies increased capital requirement measures and a number of our competitors were downgraded. Following these events, some insurers and reinsurers raised capital through equity and debt offerings. Many new Bermuda based reinsurers were formed. Some compete in the open market and others dedicate their capacity to a single sponsoring reinsurer. The competitive landscape is still evolving and the depth and breadth of market changes in reaction to the size of the hurricane losses is uncertain. The full effect of this activity on the reinsurance market and on the terms and conditions of the reinsurance contracts of the types we expect to underwrite may not be known for some time. Competition in the types of reinsurance business that we underwrite is based on many factors, including premium charges and other terms and conditions offered, services provided, ratings assigned by independent rating agencies, speed of claims payment, claims handling experience, perceived financial strength and experience and reputation of the reinsurer in the line of reinsurance to be underwritten.

Results of Operations

Three Months Ended June 30, 2006 as Compared with the Three Months Ended June 30, 2005

     Net income for the three months ended June 30, 2006 and 2005 was as follows ($ in thousands):

	2006		2005		Increase
Net income	$	81,748		67,985	$	13,763

     The increase in net income in 2006 as compared with 2005 is primarily attributable to an increase in investment income of $16,444,000 and a decrease in income tax expense of $13,417,000, partially offset by a decrease in underwriting income of $12,309,000. Underwriting income consists of net premiums earned, less losses and loss adjustment expenses (“LAE”), acquisition expenses and operating costs related to underwriting operations. The increase in net income in 2006 as compared with 2005 was also impacted by an increase in operating expenses not specifically related to underwriting operations of $744,000, an increase in interest expense of $1,276,000 and an increase in other expense of $2,912,000.

     Net premiums written and net premiums earned for the three months ended June 30, 2006 and 2005 were as follows ($ in thousands):

	2006		2005		Decrease
Net premiums written	$	309,762		422,959	$	(113,197	)
Net premiums earned	$	337,065		431,470	$	(94,405	)

     The decrease in net premiums written in 2006 is attributable to the reduction in business written in the current period in the Property and Marine and Finite Risk segments, partially offset by an increase in net premiums written in the Casualty segment which is attributable to an increase in estimated premiums relating to business written in prior periods. In addition, in order to reduce our overall net exposure to catastrophe losses, Platinum US and Platinum UK commenced ceding, on a quota share basis, 30% of new and renewal property catastrophe business effective on or after January 1, 2006.

- 24 -

The decrease in net premiums earned is due to the decrease in net premiums written and is affected by changes in the mix of business and the structure of the underlying reinsurance contracts.

     Net investment income for the three months ended June 30, 2006 and 2005 was $45,348,000 and $28,904,000, respectively. Net investment income increased in 2006 due to increased invested assets and increased yields. The increase in invested assets is attributable to positive net cash flows from operations in the twelve months since June 30, 2005 and the net proceeds from the issuance of common and preferred shares, partially offset by the repurchase of debt obligations in December 2005. Net investment income includes interest earned on funds held of $1,917,000 and $3,183,000 in 2006 and 2005, respectively. Net realized gains (losses) on investments were $14,000 and ($555,000) for the three months ended June 30, 2006 and 2005, respectively. Net realized losses on investments in 2005 include a provision of $769,000 for the permanent impairment of an investment in Inter-Ocean, Ltd., a non-public reinsurance company, included in other invested asset. Exclusive of this provision in 2005, net realized gains and losses on investments primarily result from of our efforts to manage credit quality, duration and sector allocation of the investment portfolio.

     Other income (expense) for the three months ended June 30, 2006 and 2005 was ($2,324,000) and $588,000, respectively. Other income (expense) is comprised primarily of changes in fair value of fixed maturities classified as trading, net earnings or expense on several reinsurance contracts in the Finite Risk segment that are accounted for as deposits and interest expense related to funds withheld. Other income (expense) for the three months ended June 30, 2006 includes ($1,565,000) of net unrealized losses relating to fixed maturities classified as trading and ($759,000) of net expense on reinsurance contracts accounted for as deposits. Other income (expense) for the three months ended June 30, 2005 includes $865,000 of net unrealized gains relating to fixed maturities classified as trading, $225,000 of net income on reinsurance contracts accounted for as deposits and ($502,000) of interest expense related to funds withheld.

     Losses and LAE and the resulting loss ratios for the three months ended June 30, 2006 and 2005 were as follows ($ in thousands):

	2006			2005			Decrease
Losses and LAE	$	187,464			240,852		$	(53,388	)
Losses and LAE ratios		55.6	%		55.8	%	(0.2) points

     The decrease in losses and LAE in 2006 as compared with 2005 is due primarily to the decrease in net premiums earned. The losses and LAE and the resulting losses and LAE ratios were also impacted by favorable loss development of $16,290,000, representing 4.8% of net premiums earned in 2006 and $17,256,000, representing 4.0% of net premiums earned in 2005.

     Acquisition expenses and resulting acquisition expense ratios for the three months ended June 30, 2006 and 2005 were as follows ($ in thousands):

	2006			2005			Decrease
Acquisition expenses	$	76,052			103,928		$	(27,876	)
Acquisition expense ratios		22.6	%		24.1	%	(1.5) points

     The decrease in acquisition expenses is due primarily to the decrease in net premiums earned in 2006 as compared with 2005 as well as shifts in the mix of business. The decrease in the acquisition expense ratio in 2006 as compared with 2005 is due partially to the decrease in assumed quota share contracts with ceding commissions in the Property and Marine and Finite Risk segments.

- 25 -

Acquisition costs also include increases in commissions of $816,000 in 2006, representing 0.2% of net premiums earned, related to favorable loss development from prior years. Commission increases in 2005 related to prior years were approximately $3,293,000, representing 0.8% of net premiums earned.

     Operating expenses for the three months ended June 30, 2006 and 2005 were $23,392,000 and $23,480,000, respectively. Operating expenses include 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. Operating expenses in 2006 decreased as compared with 2005 primarily due to a reduction in the amount of incentive-based compensation accrued in 2006 as compared with 2005, which was substantially offset by increases in other operating expenses.

     Net foreign currency exchange gains (losses) for the three months ended June 30, 2006 and 2005 were $414,000 and ($160,000), respectively. We routinely do business in various foreign currencies. Foreign currency exchange gains and losses result from the re-valuation into U.S. dollars of assets and liabilities denominated in foreign currencies. We periodically monitor our largest foreign currency exposures and purchase or sell foreign currency denominated invested assets to match these exposures. Net foreign currency exchange gains and losses arise as a result of fluctuations in the amounts of assets and liabilities denominated in foreign currencies as well as fluctuations in the currency exchange rates.

     Interest expense for the three months ended June 30, 2006 and 2005 was $5,450,000 and $4,174,000, respectively. The increase in 2006 as compared with 2005 is due to the increase in debt outstanding during the comparable periods. Interest expense in 2006 includes interest on the $250,000,000 of Series B 7.5% Notes due June 1, 2017 (the “Series B Notes”) as well as interest on the remaining balance of $42,840,000 of the Series B 6.371% Remarketed Senior Guaranteed Notes due November 16, 2007 (the “Remarketed Notes”). Interest expense in 2005 includes interest related to $137,500,000 of 5.25% Senior Guaranteed Notes that were part of the Equity Security Units issued in November 2002 (the “Senior Notes”) as well as interest on the Series B Notes for one month of the three months ended June 30, 2005. The Senior Notes were remarketed in August 2005 and then subsequently partially repurchased in December 2005.

     Income tax expense and the effective income tax rates for the three months ended June 30, 2006 and 2005 were as follows ($ in thousands):

	2006			2005			Decrease
Income tax expense	$	6,411			19,828		$	(13,417	)
Effective income tax rates		7.3	%		22.6	%	(15.3) points

     The decrease in income tax expense and the effective income tax rate in 2006 as compared with 2005 are due primarily to $9,150,000 of income taxes in 2005 associated with the transfer from Platinum Finance to Platinum Holdings of $183,350,000 of the proceeds from the sale of the Series B Notes. This transaction was deemed to be a taxable distribution under U.S. tax law and accordingly, subject to U.S. withholding tax. The decrease in the income tax expense and effective tax rate is also due to a higher percentage of income before income taxes being generated by Platinum Bermuda, which is not subject to corporate income tax. In 2006, the combined net income derived from Platinum Holdings and Platinum Bermuda was approximately 77.6% of the total net income before tax expense as compared with approximately 62.1% in 2005.

Six Months Ended June 30, 2006 as Compared with the Six Months Ended June 30, 2005

     Net income for the six months ended June 30, 2006 and 2005 was as follows ($ in thousands):

	2006		2005		Increase
Net income	$	158,784		141,073	$	17,711

     The increase in net income in 2006 as compared with 2005 is primarily attributable to an increase in investment income of $33,054,000 and a decrease in income tax expense of $18,012,000, partially offset by a decrease in underwriting income of $24,795,000. Underwriting income in 2006 and 2005 was impacted by net development that includes the net development of prior years unpaid losses and LAE and the related impact on premiums and profit commissions. Net favorable development, which is a component of underwriting income, was $12,098,000 in 2006 as compared with $35,633,000 in 2005. The increase in net income in 2006 as compared with 2005 was also impacted by an increase in operating expenses not specifically related to underwriting operations of $3,043,000, an increase in interest expense of $4,553,000 and a decrease in other income of $3,873,000.

     Net premiums written and net premiums earned for the six months ended June 30, 2006 and 2005 were as follows ($ in thousands):

	2006		2005		Decrease
Net premiums written	$	603,040		916,758	$	(313,718	)
Net premiums earned	$	681,366		842,510	$	(161,144	)

     The decrease in net premiums written in 2006 is primarily attributable to the reduction in business written in the Finite Risk segment as well as decreases of lesser magnitudes in certain classes written in both the Property and Marine and Casualty segments. Two significant quota share contracts in the Finite Risk segment expired. We have also commenced retroceding 30% of certain property catastrophe business on a quota share basis. The decrease in net premiums earned is due to the decrease in net premiums written and is also affected by changes in the mix of business and the structure of the underlying reinsurance contracts.

     Net investment income for the six months ended June 30, 2006 and 2005 was $88,863,000 and $55,809,000, respectively. Net investment income increased in 2006 as compared with 2005 due to increased invested assets and increased yields. The increase in invested assets is attributable to positive net cash flows from operations in the twelve months since June 30, 2005 and the net proceeds from the issuance of common and preferred shares, partially offset by the repurchase of obligations in December 2005. Net investment income includes interest earned on funds held of $4,270,000 and $5,494,000 in 2006 and 2005, respectively. Net realized gains (losses) on investments were $79,000 and ($183,000) for the six months ended June 30, 2006 and 2005, respectively. Net realized losses on investments in 2005 include a provision of $769,000 for the permanent impairment of an investment in Inter-Ocean, Ltd., a non-public reinsurance company, included in other invested asset. Exclusive of this provision in 2005, net realized gains and losses on investments primarily result from our efforts to manage credit quality, duration and sector allocation of the investment portfolio.

     Other income (expense) for the six months ended June 30, 2006 and 2005 was ($3,641,000) and $232,000, respectively. Other income (expense) is comprised primarily of changes in fair value of fixed maturities classified as trading and net earnings or expense on several reinsurance contracts in the Finite Risk segment that are accounted for as deposits. Other income (expense) for the six months ended June 30, 2006 includes ($3,238,000) of net unrealized losses relating to fixed maturities classified as

- 27 -

trading and ($403,000) of net expense on reinsurance contracts accounted for as deposits. Other income (expense) for the six months ended June 30, 2005 includes $531,000 of net unrealized gains relating to changes in fair value of fixed maturities classified as trading, $203,000 of net earnings on reinsurance contracts accounted for as deposits and ($502,000) of interest expense related to funds withheld.

     Losses and LAE and the resulting loss ratios for the six months ended June 30, 2006 and 2005 were as follows ($ in thousands):

							Increase
	2006			2005			(decrease)
Losses and LAE	$	394,238			478,550		$	(84,312	)
Loss and LAE ratios		57.9	%		56.8	%	1.1 points

     The decrease in losses and LAE in 2006 as compared with 2005 is due primarily to the decrease in net premiums earned in all segments. The increase in the loss and LAE ratio is due primarily to less net favorable loss development in 2006 as compared with 2005. Net favorable loss development was $11,931,000, representing 1.8% of net premiums earned, in 2006 as compared with approximately $33,118,000, representing 3.9% of net premiums earned in 2005. Exclusive of loss development, the loss and LAE ratio in 2006 is favorably affected by a shift in the mix of business. Net premiums earned and related losses and LAE have decreased in classes of business such as finite casualty, crop, trade credit and accident and health, which have loss ratios higher than our overall book of business. Additionally, net premiums earned have increased in catastrophe exposed classes that, in the absence of catastrophes, have lower loss ratios than our overall book of business.

     Acquisition expenses and resulting acquisition expense ratios for the six months ended June 30, 2006 and 2005 were as follows ($ in thousands):

	2006			2005			Decrease
Acquisition expenses	$	145,291			197,177		$	(51,886	)
Acquisition expense ratios		21.3	%		23.4	%	(2.1) points

     The decrease in acquisition expenses is due primarily to the decrease in net premiums earned in 2006 as compared with 2005. The decrease in the acquisition expense ratio in 2006 as compared with 2005 is due partially to the decrease in assumed quota share contracts with ceding commissions in the Property and Marine and Finite Risk segments. The decrease is also due to lower commissions on property contracts in force in 2006 that have adjustable commissions and prior year catastrophe loss experience.

     Operating expenses for the six months ended June 30, 2006 and 2005 were $46,380,000 and $43,488,000, respectively. Operating expenses include costs such as salaries, rent and like items related to reinsurance operations as well as costs associated with Platinum Holdings. The increase in operating expenses in 2006 as compared with 2005 includes an increase of $1,278,000 of fees relating to the Services and Capacity Reservation Agreement dated November 1, 2002 with RenaissanceRe Holdings, Ltd. (the “RenRe Agreement”) that provides for a periodic review of aggregate property catastrophe exposures by RenaissanceRe Holdings, Ltd. The increase in these fees is due to an increase in gross premiums written in the catastrophe classes. The increase in operating expenses also includes increased salaries and benefits, increased legal and regulatory costs, partially offset by a reduction in the amount of incentive-based compensation accrued in 2006 as compared with 2005.

     Net foreign currency exchange (gains) losses for the six months ended June 30, 2006 and 2005 were ($689,000) and $1,958,000, respectively. We routinely do business in multiple foreign currencies. Foreign currency exchange gains and losses result from the re-valuation into U.S. dollars of assets and liabilities denominated in foreign currencies. We periodically monitor our largest foreign currency exposures and purchase or sell foreign currency denominated invested assets to match these exposures. Net foreign currency exchange gains and losses arise as a result of fluctuations in the amounts of assets and liabilities denominated in foreign currencies as well as fluctuations in the currency exchange rates.

     Interest expense for the six months ended June 30, 2006 and 2005 was $10,900,000 and $6,347,000, respectively. The increase in 2006 as compared with 2005 is due to the increase in debt outstanding during the comparable periods. Interest expense in 2006 includes interest on the Series B Notes as well as interest on the remaining balance of $42,840,000 of the Remarketed Notes. Interest expense in 2005 includes interest related to $137,500,000 of 5.25% Senior Guaranteed Notes. The Senior Guaranteed Notes were remarketed in August 2005 and then subsequently partially repurchased in December 2005.

     Income tax expense and the effective income tax rates for the six months ended June 30, 2006 and 2005 were as follows ($ in thousands):

	2006			2005			Decrease
Income tax expense	$	11,763			29,775		$	(18,012	)
Effective income tax rates		6.9	%		17.4	%	(10.5) points

     The decrease in income tax expense and the effective income tax rate in 2006 as compared with 2005 is due primarily to $9,150,000 of income taxes in 2005 associated with the transfer of $183,350,000 of the proceeds from the sale of the Series B Notes from Platinum Finance to Platinum Holdings. The decrease in income tax expense and the effective tax rate is also due to a higher percentage of our income before income taxes being generated by Platinum Bermuda, which is not subject to corporate income tax. In 2006, the combined net income derived from Platinum Holdings and Platinum Bermuda was approximately 78.3% of the total net income before tax expense as compared with approximately 62.4% in 2005.

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 the three operating segments for the three and six months ended June 30, 2006 and 2005 ($ in thousands):

     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 catastrophe excess-of-loss treaties, per-risk excess-of-loss treaties and proportional treaties. This operating segment generated 27.7% and 31.9% of our net premiums written for the three months ended June 30, 2006 and 2005, respectively, and 41.6% and 34.9% of our net premiums written for the six months ended June 30, 2006 and 2005, respectively.

Three Months Ended June 30, 2006 as Compared with the Three Months Ended June 30, 2005

     Gross, ceded and net premiums written and earned for the three months ended June 30, 2006 and 2005 were as follows ($ in thousands):

					Increase
	2006		2005		(decrease)
Gross premiums written	$	102,188		136,933	$	(34,745	)
Ceded premiums written		16,564		1,980		14,584
Net premiums written		85,624		134,953		(49,329	)
Gross premiums earned		131,984		143,756		(11,772	)
Ceded premiums earned		18,892		3,087		15,805
Net premiums earned	$	113,092		140,669	$	(27,577	)

     The decrease in net premiums written and earned in 2006 as compared with 2005 is primarily due to decreases in the crop, North American property proportional, property risk excess and aviation classes of business. The decrease in crop business is due to the expiration of a significant contract. The decrease in North American property proportional and property risk excess is due to our decision to favor North American catastrophe excess business over North American property proportional and risk excess catastrophe exposed business. In addition, in order to reduce our overall net exposure to catastrophe losses, Platinum US and Platinum UK commenced ceding, on a quota share basis, 30% of new and renewal property catastrophe business effective on or after January 1, 2006. The decrease in aviation business is due to the expiration of one proportional contract. Net premiums written and earned in 2006 include a reduction in additional premiums of $2,131,000 relating to prior year events. Net premiums written and earned in 2005 include $1,147,000 of net additional premiums relating to prior year events.

     Losses and LAE and the resulting loss ratios for the three months ended June 30, 2006 and 2005 were as follows ($ in thousands):

	2006			2005			Decrease
Losses and LAE	$	27,867			58,499		$	(30,632	)
Loss and LAE ratios		24.6	%		41.6	%	(17.0) points

     The decrease in losses and LAE in 2006 as compared with 2005 is due to the decrease in net premiums earned and the difference in favorable loss development. The losses and LAE and loss and LAE ratios in 2006 and 2005 were impacted by favorable loss development of $20,008,000, representing 17.7% of net premiums earned in 2006, and $5,237,000, representing 3.7% of net premiums earned in 2005. In addition, the loss and LAE ratio is favorably impacted by the decrease in crop business that has a higher loss ratio than the remainder of the segment.

     Acquisition expenses and resulting acquisition expense ratios for the three months ended June 30, 2006 and 2005 were as follows ($ in thousands):

	2006			2005			Decrease
Acquisition expenses	$	21,239			29,695		$	(8,456	)
Acquisition expense ratios		18.8	%		21.1	%	(2.3) points

     The decrease in acquisition expenses in 2006 as compared with 2005 is primarily due to the decrease in net premiums earned. The decrease in the acquisition expense ratio results from a change in the mix of business. Net premiums earned in 2006 have a greater proportion of catastrophe excess business that has lower acquisition expenses and a smaller proportion of pro rata business that has higher acquisition expenses. Acquisition costs include increases in commissions of $682,000 in 2006, representing 0.6% of net premiums earned related to favorable loss development from prior years. Commission increases in 2005 related to prior years were approximately $2,441,000, representing 1.7% of net premiums earned.

     Other underwriting expenses for the three months ended June 30, 2006 and 2005 were $9,006,000 and $8,240,000, respectively. Other underwriting expenses include costs such as salaries, rent and like items related to property and marine underwriting operations. The increase in other underwriting expenses is due to increased property underwriting activity at Platinum Bermuda as well as increased fees relating to the RenRe Agreement. Other underwriting expenses for the three months ended June 30, 2006 and 2005 include fees of $1,164,000 and $774,000, respectively, relating to the RenRe Agreement. The increase in the fee in 2006 as compared with 2005 is due to an increase in gross premiums written in the catastrophe classes of business subject to the fee.

Six Months Ended June 30, 2006 as Compared with the Six Months Ended June 30, 2005

     Gross, ceded and net premiums written and earned for the six months ended June 30, 2006 and 2005 were as follows ($ in thousands):

Net premiums earned	$	244,636		268,866	$	(24,230	)

     Net premiums written and earned decreased in 2006 as compared with 2005 across most property classes. The most significant decreases were in the crop, North American property proportional and risk excess and aviation classes. The decrease in crop business is due to the expiration of a significant contract. The decrease in North American property proportional and property risk excess is due to our decision to favor North American catastrophe excess business over North American property proportional and risk excess catastrophe exposed business. In addition, in order to reduce our overall net exposure to catastrophe losses, Platinum US and Platinum UK commenced ceding, on a quota share basis, 30% of certain new and renewal property catastrophe business effective on or after January 1, 2006 to a non-affiliated reinsurer. The decrease in aviation business is due to the expiration of one proportional contract. Net premiums written and earned in 2006 include a reduction in additional premiums of

     The decrease in losses and LAE in 2006 as compared with 2005 is due to the decrease in net premiums earned and the difference in favorable loss development. The losses and LAE and loss and LAE ratios in 2006 and 2005 were impacted by favorable loss development of $17,392,000, representing 7.1% of net premiums earned in 2006 and $9,086,000 representing 3.4% of net premiums earned in 2005. In addition, the loss and LAE ratio is impacted by an increase in catastrophe business that, in the absence of catastrophe events, has a lower loss ratio than the remainder of the segment and a decrease in crop business that has a higher loss ratio than the remainder of the segment.

     Acquisition expenses and resulting acquisition expense ratios for the six months ended June 30, 2006 and 2005 were as follows ($ in thousands):

Acquisition expenses	$	40,888			51,684		$	(10,796	)
Acquisition expense ratios		16.7	%		19.2	%	(2.5) Points

     The decrease in acquisition expenses in 2006 as compared with 2005 is primarily due to the decrease in net premiums earned. The decrease in the acquisition expense ratio is due to a change in the mix of business. Net premiums earned in 2006 has a greater proportion of catastrophe excess business that has lower acquisition expenses and a smaller proportion of pro rata business which has higher acquisition expenses. Acquisition costs include increases in commissions of $1,024,000 in 2006, representing 0.4% of net premiums earned related to favorable loss development from prior years as compared with approximately $2,441,000, representing 0.9% of net premiums earned in 2005.

     Other underwriting expenses for the six months ended June 30, 2006 and 2005 were $19,034,000 and $15,963,000, respectively.

Other underwriting expenses for the six months ended June 30, 2006 and 2005 include fees of $4,839,000 and $3,561,000, respectively, relating to the RenRe Agreement. The increase in the fee in 2006 as compared with 2005 is due to an increase in gross premiums written in the catastrophe classes of business subject to the fee.

     Casualty

     The Casualty operating segment principally includes reinsurance treaties that cover umbrella liability, general and product liability, professional liability, workers’ compensation, casualty clash, automobile liability, surety and trade credit. This operating segment also includes accident and health treaties, which are predominantly reinsurance of health insurance products. This operating segment generated 64.3% and 44.7% of our net premiums written for the three months ended June 30, 2006 and 2005, respectively, and 63.3% and 44.1% of our net premiums written for the six months ended June 30, 2006 and 2005, respectively.

Net premiums earned	$	185,073		198,723	$	(13,650	)

     The increase in net premiums written is due to an increase in premium estimates in the umbrella and financial lines classes related to business written in prior periods. The decrease in net premiums earned is related to the year to date decrease in net premiums written and is affected by changes in the mix of business and the structure of the underlying reinsurance contracts.

     Losses and LAE and the resulting loss ratios for the three months ended June 30, 2006 and 2005 were as follows ($ in thousands):

Losses and LAE	$	127,824			127,531		$	293
Loss and LAE ratios		69.1	%		64.2	%	4.9 points

     The losses and LAE in 2006 are comparable with 2005. The increase in the loss and LAE ratio in 2006 as compared with 2005 is due to less favorable loss development in 2006 as compared with 2005. Losses and LAE included no significant loss development in 2006 and approximately $4,935,000 of net favorable loss development, representing 2.5% of net premiums earned in 2005. The net favorable loss development is primarily in casualty classes with short loss development periods. The loss ratio is also affected by changes in the mix of business within the segment.

Acquisition expense ratios		24.4	%		24.1	%	0.3 points

     The decrease in acquisition expenses is due primarily to the decrease in net premiums earned in 2006 as compared with 2005. The resulting acquisition expense ratios are comparable.

     Other underwriting expenses for the three months ended June 30, 2006 and 2005 were $7,688,000 and $8,972,000, respectively, and represent costs such as salaries, rent and like items. The resulting other underwriting expense ratios for the three months ended June 30, 2006 and 2005 were 4.2%

- 35 -

and 4.5%, respectively. The decrease in operating costs and resulting other underwriting expense ratios is primarily due to a reduction in the amount of incentive-based compensation accrued in 2006 as compared with 2005.

Six Months Ended June 30, 2006 as Compared with the Six Months Ended June 30, 2005

     Net premiums written and net premiums earned for the six months ended June 30, 2006 and 2005 were as follows ($ in thousands):

Ceded premiums earned		(18	)		460		(478	)
Net premiums earned	$	358,741			383,491	$	(24,750	)

     The decrease in net premiums written in 2006 is due to decreases in the accident and health and trade credit classes. Accident and health net premiums written have decreased as a result of deteriorating profitability in the employers’ stop loss market. The decrease in net premiums written in the trade credit class is due to less attractive reinsurance terms and conditions. The decrease in net premiums written was partially offset by an increase in premium estimates in the umbrella class related to business written in prior periods. The decrease in net premiums earned is related to the decrease in net premiums written. Net premiums written and earned are also affected by changes in the mix of business and the structure of the underlying reinsurance contracts.

Acquisition expenses	$	86,522			93,165		$	(6,643	)
Acquisition expense ratios		24.1	%		24.3	%	(0.2) points

     The decrease in acquisition expenses is due primarily to the decrease in net premiums earned in 2006 as compared with 2005. The resulting acquisition expense ratios are comparable.

     Other underwriting expenses for the six months ended June 30, 2006 and 2005 were $14,023,000 and $16,285,000, respectively. Other underwriting expenses include costs such as salaries, rent and like items related to casualty underwriting operations. The resulting other underwriting expense ratios for the six months ended June 30, 2006 and 2005 were 3.9% and 4.2%, respectively. The decreases in operating costs and resulting other underwriting expense ratios are primarily due to a reduction in the amount of incentive-based compensation accrued in 2006 as compared with 2005.

     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. The classes of risks underwritten through finite risk contracts are generally consistent with the classes covered by traditional products. In exchange for contractual features that limit our downside risk, we provide the potential for significant profit commission to the ceding company. Due to the 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 loss and loss adjustment expense ratios. 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. This operating segment represented 8.0% and 23.4% of our net premiums written for the three months ended June 30, 2006 and 2005, respectively, and (4.9%) and 21.0% of our net premiums written for the six months ended June 30, 2006 and 2005, respectively. The ongoing investigations by legal and regulatory authorities have curtailed demand for finite risk products in 2006 and 2005.

Three Months Ended June 30, 2006 as Compared with the Three Months Ended June 30, 2005

     Net premiums written and net premiums earned for the three months ended June 30, 2006 and 2005 were as follows ($ in thousands):

					Increase
	2006		2005		(decrease)
Gross premiums written	$	28,558		102,963	$	(74,405	)

Net premiums earned	$	38,900		92,078	$	(53,178	)

- 37 -

     The Finite Risk portfolio consists of a small number of contracts that can be large in premium size and, consequently, overall premium volume may vary significantly from year to year. The decrease in net premiums written and earned is primarily due to the termination of two finite casualty contracts.

     Losses and LAE, acquisition expenses and the resulting ratios for the three months ended June 30, 2006 and 2005 were as follows ($ in thousands):

							Increase
	2006			2005			(decrease)
Losses and LAE	$	31,773			54,822		$	(23,049	)
Loss and LAE ratios		81.7	%		59.5	%	22.2 points

Loss, LAE and acquisition expense ratios		106.5	%		88.0	%	18.5 points

     The decrease in losses, LAE and acquisition expenses in 2006 as compared with 2005 is due primarily to the decrease in net premiums earned. The increase in the loss, LAE and acquisition expense ratio in 2006 as compared with 2005 is primarily due to the unfavorable net development from prior years in 2006 as compared with the favorable net development from prior years in 2005. Losses, LAE and acquisition expenses included net unfavorable development of approximately of $3,844,000, representing 9.9% of net premiums earned in 2006, as compared with net favorable development of approximately $6,232,000, representing 6.8% of net premiums earned in 2005. The loss ratio is also affected by the continued shift in the mix of business toward finite casualty that has a higher combined ratio than the remainder of the segment.

     Other underwriting expenses for the three months ended June 30, 2006 and 2005 were $1,019,000 and $1,333,000, respectively, and represent costs such as salaries, rent and like items. The decrease in other underwriting expenses is due to cost reductions in the segment as a result of the decline in underwriting activity. In addition, due to the decline in the volume of underwriting activity in the segment, the percentage of common operating and administrative costs that are allocated to the segment has also declined.

Six Months Ended June 30, 2006 as Compared with the Six Months Ended June 30, 2005

     Net premiums written and net premiums earned for the six months ended June 30, 2006 and 2005 were as follows ($ in thousands):

Net premiums earned	$	77,989			190,153	$	(112,164	)

- 38 -

     The decrease in net premiums written and earned is primarily attributable to the termination of two significant finite casualty contracts. One of the contracts was terminated effective January 1, 2006 on a cut-off basis, which resulted in the return of previously written but unearned premium. The ongoing investigations by legal and regulatory authorities have curtailed demand for finite risk products in 2006 and 2005.

     Losses and LAE, acquisition expenses and the resulting ratios for the six months ended June 30, 2006 and 2005 were as follows ($ in thousands):

							Increase
	2006			2005			(decrease)
Losses and LAE	$	62,154			114,042		$	(51,888	)
Loss and LAE ratios		79.7	%		60.0	%	19.7 points

Loss, LAE and acquisition expense ratios		102.6	%		87.5	%	15.1 points

     The decrease in losses, LAE and acquisition expenses in 2006 as compared with 2005 is due primarily to the decrease in net premiums earned. The increase in the loss, LAE and acquisition expense ratio in 2006 as compared with 2005 is primarily due to the unfavorable net development from prior years in 2006 as compared with the favorable net development from prior years in 2005. Losses, LAE and acquisition expenses included net unfavorable development of approximately $6,030,000, representing 7.7% of net premiums earned in 2006, as compared with net favorable development of approximately $14,449,000, representing 7.6% of net premiums earned in 2005. The loss ratio is also affected by the continued shift in the mix of business toward finite casualty that has a higher combined ratio than the remainder of the segment.

     Other underwriting expenses for the six months ended June 30, 2006 and 2005 were $1,944,000 and $2,904,000, respectively, and represent costs such as salaries, rent and like items. The decrease in other underwriting expenses is due to cost reductions in the segment as a result of the decline in underwriting activity in the segment. In addition, due to the decline in underwriting activity in the segment, the percentage of common operating and administrative costs that are allocated to the Finite Risk segment has also declined.

Financial Condition, Liquidity and Capital Resources

     Financial Condition

     Cash and cash equivalents and investments as of June 30, 2006 and December 31, 2005 were as follows ($ in thousands):

- 39 -

	June 30,		December 31,		Increase
	2006		2005		(decrease)
Cash and cash equivalents	$	710,830		820,746	$	(109,916	)
Fixed maturity securities		3,211,755		2,987,703		224,052

Other invested asset		5,000		5,000		–
Total	$	4,010,860		3,830,428	$	180,432

     The net increase in total cash and cash equivalents and investments is due to positive net cash flows from operations in the six months ended June 30, 2006. This increase was partially offset by the decline in fair value of our investments. Our available-for-sale and trading portfolios are primarily composed of diversified, high quality, predominantly publicly traded fixed maturity securities. Our investment portfolio, excluding cash and cash equivalents, had a weighted average duration of 3.2 years as of June 30, 2006. We maintain and periodically update our overall duration target for the portfolio and routinely monitor the composition of, and cash flows from, the portfolio to maintain liquidity necessary to meet our obligations.

     Premiums receivable include significant estimates. Premiums receivable as of June 30, 2006 of $401,746,000 include $351,594,000 that is based upon estimates. Premiums receivable as of December 31, 2005 of $567,449,000 include $496,603,000 that is based upon estimates. An allowance for uncollectible premiums is established for possible non-payment of such amounts due, as deemed necessary. As of June 30, 2006, based on our historical experience, the general profile of our ceding companies and our ability, in most cases, to contractually offset premiums receivable with losses and LAE or other amounts payable to the same parties, we did not establish an allowance for uncollectible premiums receivable.

     Unpaid losses and LAE as of June 30, 2006 of $2,343,605,000 include $1,636,506,000 of estimates of claims that were incurred but not reported (“IBNR”). Unpaid losses and LAE as of December 31, 2005 of $2,323,990,000 includes $1,812,245,000 of IBNR. IBNR decreased during the six months ended June 30, 2006 as losses related to the 2005 Hurricanes and hurricane losses of 2004 were reported and paid. Paid losses related to the 2005 Hurricanes and hurricane losses of 2004 during the six months ended June 30, 2006 were approximately $137,411,000.

     Commissions payable as of June 30, 2006 of $141,823,000 include $121,949,000 that represent estimates that are primarily based upon premium estimates. Commissions payable as of December 31, 2005 of $186,654,000 include $167,949,000 that is based upon estimates.

     Sources of Liquidity

     Our sources of funds consist of premiums written, investment income, proceeds from sales and redemption of investments, losses recovered from retrocessionaires, and cash and cash equivalents held as well as the sale of debt or equity securities. Net cash flows provided by operations, excluding trading securities activities, for the six months ended June 30, 2006 were $346,708,000.

     Platinum Holdings is a holding company that conducts no reinsurance operations of its own. All of its reinsurance operations are conducted through its wholly owned operating subsidiaries:

- 40 -

Platinum Bermuda, Platinum US and Platinum UK. As a holding company, the cash flows of Platinum Holdings consist primarily of dividends, interest 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 dividends to its preferred and common shareholders.

     We filed an unallocated universal shelf registration statement with the SEC, which the SEC declared effective on November 8, 2005. This shelf registration statement provides the capacity to 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 the above, including debt securities of Platinum Finance, unconditionally guaranteed by Platinum Holdings. To affect any such sales from time to time, Platinum Holdings and/or Platinum Finance will file one or more supplements to the prospectus forming a part of such registration statement, which will provide details of any proposed offering. In December 2005, Platinum Holdings issued $132,909,000 of Common Shares and $173,363,000 of mandatory convertible preferred shares under this unallocated shelf registration statement.

     On December 1, 2005, certain reform measures simplifying the process for conducting registered securities offerings under the Securities Act came into effect. The new rules provide that shelf registration statements of certain well-known seasoned issuers, such as Platinum Holdings, are eligible for effectiveness automatically upon filing. Should Platinum Holdings seek to issue securities in the future, it may make use of the new rules.

     On October 21, 2005 we entered into a three-year $200,000,000 credit agreement with a syndicate of lenders. The credit agreement consists of a $100,000,000 senior unsecured credit facility available for revolving borrowings and letters of credit, and a $100,000,000 senior secured credit facility available for letters of credit. The revolving line of credit will be available for the working capital, liquidity and our general corporate requirements. The interest rate on borrowings under the credit facility is based on our election of either: (1) LIBOR plus 50 basis points or (2) the higher of: (a) the prime interest rate of the lead bank providing the credit facility, or (b) the federal funds rate plus 50 basis points. The interest rate based on LIBOR rate would decrease by up to 10 basis points or increase by up to 12.5 basis points should our senior unsecured debt credit rating increase or decrease. We intend to amend our existing credit agreement in order to increase the aggregate amount of borrowings and letters of credit that are available to us by as much as $200,000,000.

     Liquidity Requirements

     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, the acquisition of and investment in businesses, capital expenditures, purchase of retrocessional contracts and payment of taxes. The catastrophe losses of 2005 and, to a lesser extent, the catastrophe losses in 2004, will create an unusually large amount of loss and LAE payments over the next year that could adversely affect net cash flows from operations.

     Platinum Bermuda and Platinum UK are not licensed, approved or accredited as reinsurers anywhere in the United States and, therefore, under the terms of most of their contracts with United States ceding companies, they are required to provide collateral to their ceding companies for unpaid ceded liabilities in a form acceptable to state insurance commissioners. Typically, this type of collateral takes the form of a letter of credit issued by a bank, the establishment of a trust, or funds withheld. Platinum Bermuda and Platinum UK have obtained letters of credit through commercial banks and may be required to provide the banks with a security interest in certain investments of Platinum Bermuda and Platinum UK.

- 41 -

     In 2002, the Company and The St. Paul Travelers Companies, Inc., formerly The St. Paul Companies, Inc., (“St. Paul”) entered into several agreements for the transfer of continuing reinsurance business and certain related assets of St. Paul. Among these agreements were quota share retrocession agreements effective November 2, 2002 under which the Company assumed from St. Paul unearned premiums, unpaid losses and LAE and certain other liabilities on reinsurance contracts becoming effective in 2002 (the “Quota Share Retrocession Agreements”). Platinum US is obligated to collateralize the liabilities assumed from St. Paul under the Quota Share Retrocession Agreements. Platinum Bermuda and Platinum US have reinsurance and other contracts that also require them to provide collateral to ceding companies should certain events occur, such as a decline in the rating by A.M. Best Company, Inc. (“A.M. Best”) below specified levels or a decline in statutory equity below specified amounts, or when certain levels of liabilities assumed from ceding companies are attained. Some reinsurance contracts also have special termination provisions that permit early termination should certain events occur.

     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 presence 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 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.

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

     The 2005 Hurricanes caused significant losses to insurers and reinsurers during the third and fourth quarters of 2005. Following these events, rating agencies strengthened the capital requirements for companies with catastrophe exposures. Many reinsurers added capital through equity and debt offerings as well as the creation of special purpose vehicles to share in business underwritten by the sponsor, but some saw their financial strength ratings downgraded in any case. In contrast, our A.M. Best rating of “A” (Excellent) was affirmed, which we believe strengthened our relative position in the marketplace.

     A number of new Bermuda-based reinsurance companies were formed after the 2005 Hurricanes. We believe that, although most of these companies were active participants in the property catastrophe markets since January 1, 2006, they concentrated their activity in the areas with significant capacity shortages. We believe their presence had little impact on our ability to access the business we targeted and achieve the rate increases we desired. We expect these conditions to continue for the remainder of 2006.

     We believe 2006 renewal negotiations have been more contentious than usual. We experienced account turnover across all lines of business. However, terms and conditions on most of our renewed treaties improved or remained substantially unchanged depending on the line of business.

- 42 -

For reinsurance with exposures to North American hurricanes, demand has continued to exceed capacity and rates have increased further since the January 1 renewal season.

     For the Property and Marine segment, underlying primary rates and reinsurance rates have increased considerably, particularly for risks exposed to Atlantic hurricanes. During 2006 we have achieved average rate increases of over 50% on our U.S. property catastrophe excess renewal business and approximately 10% on our non-U.S. property catastrophe excess renewal business, as well as average rate increases of approximately 45% on our marine renewal business. Despite having increased our assumptions for the frequency and severity of U.S. windstorm catastrophe exposures, we believe these rate increases result in a portfolio of catastrophe exposed business with expected profitability that is higher than the expected profitability of last year’s portfolio. Per risk excess rate increases averaged almost 30% in our U.S. renewal business and approximately 5% in our international renewal business. The catastrophe exposure contained within the U.S. per risk excess contracts has been reduced through more restrictive terms and conditions.

     During 2006 we wrote more property catastrophe excess-of-loss business and less property risk excess-of-loss and pro-rata business. Property risk excess-of-loss and pro-rata business typically generates relatively more premium than property catastrophe excess-of-loss business having a similar risk level. However, we believe property catastrophe excess-of-loss business generally provides more quantifiable catastrophe exposure and is currently priced more attractively.

     For 2006, we have targeted our net probable maximum loss from catastrophe exposures at various occurrence levels to be relatively lower as a percentage of our expected total capital than prior years. For example, we expect our net probable maximum loss from catastrophe exposures at the one in 250 year occurrence level to be no more than approximately 20% of total capital for 2006 versus approximately 30% of total capital for 2005. For the balance of the year we will seek to write business that does not significantly contribute to our largest probable maximum loss exposures. We believe this lower level of net catastrophe exposure will reduce the expected volatility of our operating results.

     Given the magnitude of recent hurricane losses for the insurance and reinsurance industry in general and expectations for an active Atlantic hurricane season in 2006, we believe there is a heightened perception of risk among ceding companies, reinsurers and rating agencies. Accordingly, demand for property catastrophe risk transfer may increase beyond current levels. We expect that, as recent revisions to commercial catastrophe models are adopted and new rating agency capital requirements are better understood, there will be continued U.S. market hardening for property and marine business.

     For the Casualty segment pricing has begun to show signs of softening. Ceding companies are willing to increase retentions and reinsurers are competing for participation on the best treaties. After the 2005 Hurricanes rates had stabilized in certain lines of business, however, rates have started to decline again in 2006. As a result, we believe that the business underwritten during 2006 has a slightly lower level of expected profitability as compared with the business we wrote during a similar period in 2005. We have continued to pull back in accident and health and financial lines and have begun to cut back in high excess casualty and umbrella. We have written approximately the same amount of surety, political risk, medical malpractice and regional business as we did during the comparable period in 2005. 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 expect these conditions to continue to weaken through the remainder of 2006 and that fewer casualty opportunities will be attractive. We believe that our rating, capitalization and reputation as a lead casualty reinsurer positions us well to write profitable business as the opportunities arise.

- 43 -

     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 continues to reduce demand for limited risk transfer products in 2006. We believe we can deploy our human and financial capital more profitably in other lines of business. As a result, we are devoting fewer underwriting and pricing resources to this segment than in prior years and wrote a relatively small amount of finite business during 2006 relative to the comparable period last year. We expect the relatively low level of demand will continue during 2006.

Critical Accounting Policies, Estimates and Judgments

     It is important to understand the Company’s accounting policies in order to understand its financial position and results of operations. Management considers certain of these policies 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 differ from these estimates. The Company’s critical accounting policies involve premiums written and earned, unpaid losses and LAE, reinsurance, investments, income taxes and stock-based compensation. The critical accounting policies presented herein are also discussed in the notes to the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2005.

     Premiums

     Assumed reinsurance premiums are recognized as revenues when premiums become earned proportionately over the coverage period. Net premiums earned are recorded in the statement of operations, net of the cost of retrocession. Net premiums written not yet recognized as revenue are recorded on the balance sheet as unearned premiums, gross of any ceded unearned premiums.

     Due to the nature of reinsurance, ceding companies routinely report and remit premiums subsequent to the contract coverage period. Consequently, reinsurance premiums written include amounts reported by the ceding companies, supplemented by estimates of premiums that are written but not reported (“WBNR”). The premium estimation process considers the terms and conditions of the reinsurance contracts and assumes that the contracts will remain in force until expiration. The estimation of written premiums could be affected by early cancellation, election of contract provisions for cut-off and return of unearned premiums or other contract disruptions. In addition to estimating WBNR, the Company estimates the portion of premiums earned but not reported (“EBNR”). The Company also estimates the expenses associated with these premiums in the form of losses, LAE and commissions. The time lag involved in the process of reporting premiums is shorter than the lag in reporting losses. Premiums are generally reported within two years.

     When estimating premiums written and earned, each of our reinsurance subsidiaries segregates business into classes by type of coverage and type of contract (approximately 80 classes). Within each class, business is further segregated by the year in which the contract incepted (the “Underwriting Year”), starting with 2002. Estimates of WBNR and EBNR are made for each class and Underwriting Year. Premiums are estimated based on ceding company estimates and our own judgment after considering factors such as the ceding company’s historical premium versus projected premium, the ceding company’s history of providing accurate estimates, anticipated changes in the marketplace and the ceding company’s competitive position therein, reported premiums to date and the anticipated impact of proposed underwriting changes. The net impact on the results of operations of changes in estimated premiums earned is reduced by the losses and acquisition expenses related to such premiums earned.

- 44 -

     Premiums receivable include premiums billed and in the course of collection as well as WBNR. WBNR is the component of premiums receivable that is subject to judgment and uncertainty. Premiums receivable as of June 30, 2006 of $401,746,000 include $351,594,000 of WBNR that is based upon estimates. The appropriateness of WBNR is evaluated in light of the actual premium reported by the ceding companies and any adjustments to WBNR and EBNR that represent premiums earned are accounted for as changes in estimates and are reflected in results of operations in the period in which they are made. The initial estimates of premiums derived by our underwriting function in respect of the six months ended June 30, 2006 were evaluated. The cumulative impact of our evaluation in respect of premiums receivable as of June 30, 2006 was to reduce WBNR by approximately $39,800,000 or 9.9%. WBNR premium receivable in our North American casualty claims-made excess of loss reinsurance class was $71,406,000 of the $351,594,000 as of June 30, 2006 and reflects a $10,700,000 reduction from initial premium estimates. We believe that we reasonably could have made an adjustment of between $0 and $10,700,000 with respect to this reinsurance class at June 30, 2006. Had we not made this adjustment, the reinsurance premiums receivable for this class would have been $412,400,000 at June 30, 2006.

     Due to the time lag inherent in the reporting of premiums by ceding companies, a significant portion of amounts included as premiums written and premiums earned represents estimated premiums and are not currently due based on the terms of the underlying contracts. Premiums earned, including EBNR, are a measure of exposure to losses, LAE and acquisition expenses. Consequently, when previous estimates of premiums earned are increased or decreased, the related provisions for losses and LAE and acquisition costs previously recorded are also increased or decreased. An allowance for uncollectible premiums is established for possible non-payment of such amounts due, as deemed necessary. As of June 30, 2006, based on our historical experience, the general profile of our ceding companies and our ability in most cases to contractually offset those premium receivables against losses and loss adjustment expense or other amounts payable to the same parties, we did not establish an allowance for uncollectible premiums receivable.

     Certain of the Company’s reinsurance contracts include provisions that adjust premiums or acquisition expenses based upon the loss experience under the contracts. Reinstatement premiums and additional premiums are recognized in accordance with the provisions of assumed reinsurance contracts, based on loss experience under such contracts. Reinstatement premiums are the premiums charged for the restoration of the reinsurance limit of a reinsurance contract to its full amount, generally coinciding with the payment by the reinsurer of losses. These premiums relate to the future coverage obtained for the remainder of the initial policy term and are earned over the remaining policy term. Any unearned premium existing at the time a contract limit is exhausted or reinstated is immediately earned. Additional premiums are those premiums triggered by losses and not related to reinstatement of limits and are immediately earned. An allowance for uncollectible premiums is established for possible non-payment of such amounts due, as deemed necessary.

     Unpaid Losses and LAE

     One of the most significant judgments made by management in the preparation of financial statements is the estimation of unpaid losses and LAE, also referred to as “loss reserves.” Unpaid losses and LAE include estimates of the cost of claims that were reported but not yet paid, generally referred to as case reserves, and the cost of claims that were incurred but not reported IBNR. These liabilities are balance sheet estimates of future amounts required to pay losses and LAE for reinsured claims for which we are liable and that have occurred at or before the balance sheet date. Every quarter, the Company’s actuaries prepare estimates of the loss reserves based on established actuarial techniques. Because the ultimate amount of unpaid losses and LAE is uncertain, we believe that the quantitative techniques used to estimate these amounts are enhanced by professional and managerial judgment. Company

management reviews these estimates and determines its best estimate of the liabilities to record in the Company’s financial statements.

     While the Company commenced operations in 2002, the business written is sufficiently similar to the historical business of St. Paul Re such that the Company uses the historical loss experience of this business, which is periodically updated by St. Paul Re, to estimate its initial expected ultimate losses and its expected patterns of reported losses. These patterns can span more than a decade and, given its own limited history, the availability of the St. Paul Re data is a valuable asset of the Company.

     The Company does not establish liabilities until the occurrence of an event that may give rise to a loss. When an event of sufficient magnitude occurs, the Company may establish a specific IBNR reserve. Generally, this is done following a catastrophe that affects many ceding companies. Ultimate losses and LAE are based on management’s judgment and reflect estimates gathered from ceding companies, estimates of insurance industry losses gathered from public sources and estimates derived from catastrophe modeling software.

     Unpaid losses and LAE represent management’s best estimates, at a given point in time, of the ultimate settlement and administration costs of claims incurred, and it is possible that the ultimate liability may materially differ from such estimates. Such estimates are not precise due to the fact that, among other things, they are based on predictions of future developments and estimates of future trends in claim severity and frequency and other factors. Because of the degree of reliance that the Company necessarily places on ceding companies for claims reporting, the associated time lag, the low frequency/high severity nature of some of the business that the Company underwrites and the varying reserving practices among ceding companies, the Company’s reserve estimates are highly dependent on management judgment and are therefore uncertain. Estimates of unpaid losses and LAE are periodically re-estimated and adjusted as new information becomes available. Any such adjustments are accounted for as changes in estimates and are reflected in results of operations in the period in which they are made.

     The gross liabilities recorded on the Company’s balance sheet as of June 30, 2006 for unpaid losses and LAE were $2,343,605,000. The following table sets forth a breakdown between case reserves and IBNR by segment at June 30, 2006 ($ in thousands):

	Property
	and Marine		Casualty		Finite Risk		Total
Case reserves	$	397,329		206,462		103,308	$	707,099
IBNR		321,386		1,060,336		254,784		1,636,506
Total unpaid losses and LAE	$	718,715		1,266,798		358,092	$	2,343,605

     Case reserves are usually based upon claim reports received from ceding companies. The information we receive varies by ceding company and may include paid losses, case reserves, and an estimated provision for IBNR reserves. Case reserves may be increased or reduced by our claims personnel based on receipt of additional information, including information received from ceding companies. IBNR is based on actuarial methods including the loss ratio method, the Bornhuetter-Ferguson method and the chain ladder method. IBNR related to a specific event may be based on our estimated exposure to an industry loss and may include the use of catastrophe modeling software.

     Generally, initial actuarial estimates of IBNR not related to a specific event are based on the loss ratio method applied to each Underwriting Year for each class of business. Actual paid losses and case reserves, generally referred to as reported losses, are subtracted from expected ultimate losses to determine IBNR. The initial expected ultimate losses involve management judgment and are based on:

- 46 -

(i) contract by contract expected loss ratios derived from our pricing process, and (ii) historical loss ratios of the Company and St. Paul Re adjusted for rate changes and trends. These judgments take into account management’s view of past, current and future: (i) market conditions, (ii) changes in the business underwritten, (iii) changes in timing of the emergence of claims and (iv) other factors that may influence expected ultimate losses.

     Over time, as a greater number of claims are reported, actuarial estimates of IBNR are based on the Bornhuetter-Ferguson and the chain ladder techniques. The Bornhuetter-Ferguson technique utilizes actual reported losses and expected patterns of reported losses, taking the initial expected ultimate losses into account to determine an estimate of expected ultimate losses. This technique is most appropriate when there are few reported claims and a relatively less stable pattern of reported losses. The chain ladder technique utilizes actual reported losses and expected patterns of reported losses to determine an estimate of expected ultimate losses that is independent of the initial expected ultimate losses. This technique is most appropriate when there are a large number of reported losses with significant statistical credibility and a relatively stable pattern of reported losses.

     When estimating unpaid losses and LAE, each of our reinsurance subsidiaries segregates business into classes by type of coverage and type of contract (approximately 80 classes). Within each class the business is further segregated by Underwriting Year, starting with 2002.

     Multiple point estimates using a variety of actuarial techniques are calculated for many, but not all, of our 80 classes of coverage for each Underwriting Year. We do not believe that these multiple point estimates are or should be considered a range. Our actuaries consider each class and determine the most appropriate point estimate based on the characteristics of the particular class and other relevant factors such as historical ultimate loss ratios, the presence of individual large losses and known occurrences that have not yet resulted in reported losses. For some classes of business our actuaries believe that a review of individual contract information improves the loss reserve estimate. For example, individual contract review is particularly important for the Finite Risk segment and the accident and health class within the Casualty segment. Once our actuaries make their determinations of the most appropriate point estimate for each class, this information is aggregated and reviewed and approved by executive management. At June 30, 2006 the liability for unpaid losses and LAE that we recorded includes the point estimates of IBNR prepared by our actuaries.

     Generally, North American casualty excess business has the longest pattern of reported losses and, therefore, loss estimates have a higher degree of uncertainty than other reinsurance classes. IBNR for these classes at June 30, 2006 was $803,000,000, which was 49% of the total IBNR at that date. Because estimates of unpaid losses and LAE related to North American casualty excess business have a higher degree of uncertainty, we would not consider a variance of five percentage points from the initial expected loss ratio to be unusual. As an example, a change in the initial expected loss ratio from 66% to 71% would result in an increase of the IBNR for these classes by $74,500,000. This equates to approximately 8% of the liability for total unpaid losses and LAE for these classes at June 30, 2006. As another example, if the estimated pattern of reported losses was accelerated by 5% the IBNR for these classes would decrease by $2,700,000, which is less than 1%. We have selected these two inputs as examples of sensitivity analyses because we believe that the two most important inputs to the reserve estimation methodologies described above are the initial expected loss ratio and the estimated pattern of reported losses.

     The pattern of reported losses is determined utilizing actuarial analysis, including management’s judgment, and is based on historical patterns of paid losses and reporting of case reserves to the Company, as well as industry patterns. Information that may cause historical patterns to differ from future patterns is considered and reflected in expected patterns as appropriate. For property and health

- 47 -

coverages these patterns indicate that a substantial portion of the ultimate losses are reported within 2 to 3 years after the contract is effective. Casualty patterns can vary from 3 years to over 20 years depending on the type of business.

     In property classes, there can be additional uncertainty in loss estimation related to large catastrophe events. With wind events, such as hurricanes, the damage assessment process may take more than a year. The cost of rebuilding is subject to increase due to supply shortages for construction materials and labor. In the case of earthquakes, the damage assessment process may take several years as buildings are discovered to have structural weaknesses not initially detected. The uncertainty inherent in loss estimation is particularly pronounced for casualty coverages, such as umbrella liability, general and product liability, professional liability and automobile liability, where information, such as required medical treatment and costs for bodily injury claims, emerges over time. In the overall loss reserving process, provisions for economic inflation and changes in the social and legal environment are considered.

     Loss reserve calculations for primary insurance business are not precise in that they deal with the inherent uncertainty of future developments. Primary insurers must estimate their own losses, often based on incomplete and changing information. Reserving for reinsurance business introduces further uncertainties compared with reserving for primary insurance business. The uncertainty in the reserving process for reinsurers is due, in part, to the time lags inherent in reporting from the original claimant to the primary insurer and then to the reinsurer. As a predominantly broker market reinsurer for both excess-of-loss and proportional contracts, the Company is subject to a potential additional time lag in the receipt of information as the primary insurer reports to the broker who in turn reports to the Company. As of June 30, 2006, we did not have any significant back-log related to our processing of assumed reinsurance information.

     Since we rely on information regarding paid losses, case reserves and IBNR provided by ceding companies in order to assist us in estimating our liability for unpaid losses and LAE, we maintain certain procedures in order to help determine the completeness and accuracy of such information. Periodically, management assesses the reporting activities of these companies on the basis of qualitative and quantitative criteria. In addition to conferring with ceding companies or brokers on claims matters, our claims personnel conduct periodic audits of specific claims and the overall claims procedures of our ceding companies at their offices. We rely on our ability to effectively monitor the claims handling and claims reserving practices of ceding companies in order to help establish the proper reinsurance premium for reinsurance agreements and to establish proper loss reserves. Disputes with ceding companies have been rare and generally have been resolved through negotiation.

     In addition to the inherent uncertainty of estimating unpaid losses and LAE, our estimates with respect to the 2005 Hurricanes are subject to an unusually high level of uncertainty arising out of complex and unique causation and coverage issues associated with the attribution of losses to wind or flood damage or other perils such as fire, business interruption or riot and civil commotion. For example, the underlying policies generally do not cover flood damage; however, water damage caused by wind may be covered. Our actual losses from the 2005 Hurricanes may exceed our estimates as a result of, among other things, the attribution of losses to coverages that for the purpose of our estimates we assumed would not be exposed, which may be affected by class action lawsuits or state regulatory actions. We expect that these issues will not be resolved for a considerable period of time and may be influenced by evolving legal and regulatory developments.

- 48 -

     Reinsurance

     Premiums written, premiums earned and losses and LAE reflect the net effects of assumed and ceded reinsurance transactions. Reinsurance accounting is followed for assumed and ceded transactions when risk transfer requirements have been met. Risk transfer analysis evaluates significant assumptions relating to the amount and timing of expected cash flows, as well as the interpretation of underlying contract terms. Reinsurance contracts that do not transfer sufficient insurance risk are accounted for as reinsurance deposit liabilities with interest expense charged to other income and credited to the liability.

     Investments

     In accordance with our investment guidelines, our investment portfolio consists of diversified, high quality, predominantly publicly traded fixed maturity securities. Fixed maturity securities for which we may not have the positive intent to hold until maturity are classified as available-for-sale and reported at fair value, with unrealized gains and losses excluded from net income and reported in other comprehensive income as a separate component of shareholders’ equity, net of deferred taxes. Fixed maturity securities for which we have the intent to sell prior to maturity are classified as trading securities and reported at fair value, with unrealized gains and losses included in other income and the related deferred income tax included in income tax expense. Securities classified as trading securities are generally denominated in foreign currencies and are intended to match net liabilities denominated in foreign currencies in order to minimize net exposures arising from fluctuations in foreign currency exchange rates. Realized gains and losses on sales of investments are determined on a specific identification basis. Investment income is recorded when earned and includes the amortization of premiums and accretion of discounts on investments.

     We believe we have the ability to hold any specific security to maturity. This is based on current and anticipated future positive net cash flows from operations that are expected to generate sufficient liquidity in order to meet our obligations. However, in the course of managing investment credit risk, asset liability duration or other aspects of the investment portfolio, the Company may decide to sell any specific security. The Company routinely reviews its available-for-sale investments to determine whether unrealized losses represent temporary changes in fair value or are 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 duration and magnitude of an unrealized loss, specific credit events and the Company’s ability and intent to hold a security for a sufficient period of time for the value to recover the unrealized loss. If the Company has determined that an unrealized loss on a security is other than temporary, the Company writes down the carrying value of the security to its current fair value and records a realized loss in the statement of operations.

     Income Taxes

     Platinum Holdings and Platinum Bermuda are domiciled in Bermuda. Under current Bermuda law, they are not taxed on any Bermuda income or capital gains and they have received an assurance from the Bermuda Minister of Finance that if any legislation is enacted in Bermuda that would impose tax computed on profits or income, or computed on any capital asset, gain or appreciation, or any tax in the nature of estate duty or inheritance tax, then the imposition of any such tax will not be applicable to Platinum Holdings or Platinum Bermuda or any of their respective operations, shares, debentures or other obligations until March 28, 2016. The Company also has subsidiaries in the United States, United Kingdom and Ireland that are subject to the tax laws thereof.

     We apply the asset and liability method of accounting for income taxes. Under the asset and liability method, deferred tax assets and liabilities are recognized for the future tax consequences

- 49 -

attributable to differences between the financial statement carrying values of existing assets and liabilities and their corresponding tax bases. Deferred tax assets and liabilities are measured using enacted tax rates applicable to taxable income in the years in which the taxes related to those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period the change is enacted. A valuation allowance is established for deferred tax assets where it is more likely than not that future tax benefits will not be realized.

     Share-Based Compensation

     We adopted Statement of Financial Accounting Standards No. 123R “Share-Based Payment” (“SFAS 123R”) on the modified prospective method effective January 1, 2006. SFAS 123R establishes standards for the accounting for transactions in which an entity exchanges its equity instruments for goods or services. SFAS 123R requires that, prospectively, compensation costs be recognized for the fair value of all share options over their vesting period, including the cost related to the unvested portion of all outstanding share options as of December 31, 2005.

     Prior to January 1, 2006, we accounted for share based compensation using Statement of Financial Accounting Standards No. 123 “Accounting for Awards of Stock Based Compensation to Employees” and Statement of Financial Accounting Standards No. 148 “Accounting for Stock-Based Compensation-Transition and Disclosure” (“SFAS 148”). In accordance with the transition rules of SFAS 148, we elected to continue using the intrinsic value method of accounting for our share-based awards granted to employees established by Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees” (“APB 25”) for share options granted in 2002. Under APB 25, if the exercise price of our employee share options is equal to or greater than the fair market value of the underlying shares on the date of the grant, no compensation expense is recorded.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market and Credit Risk

     The Company’s 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. The Company’s strategy to limit this risk is to place its investments in high quality credit issues and to limit the amount of credit exposure with respect to any one issuer or asset class. The Company also selects investments with characteristics such as duration, yield, currency and liquidity to reflect, in the aggregate, the underlying characteristics of our unpaid losses and LAE. The Company attempts to minimize the credit risk by actively monitoring the portfolio and requiring a minimum average credit rating for its portfolio of A2 as defined by Moody’s Investor Service (“Moody’s”). As of June 30, 2006, the portfolio, excluding cash and short-term investments, has a dollar weighted average credit rating of Aa2 as defined by Moody’s.

     The Company has 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 premium receivables, we have established standards for ceding companies and, in most cases, have a contractual right of offset thereby allowing the Company to settle claims net of any premium 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 or from retrocessionaires whose obligations are fully collateralized. The financial performance and rating status of all material retrocessionaires is routinely monitored.

- 50 -

     In accordance with industry practice, the Company frequently pays 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, the Company 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 the Company and the ceding company is no longer liable to the Company for those amounts whether or not the funds are actually received by the Company. Consequently, the Company assumes a degree of credit risk associated with its brokers during the premium and loss settlement process. To mitigate credit risk related to reinsurance brokers, the Company has established guidelines for brokers and intermediaries.

Interest Rate Risk

     The Company is 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 certain principal payments. 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. The aggregate hypothetical impact on our fixed maturity portfolio, generated from an immediate parallel shift in the treasury yield curve, as of June 30, 2006 is as follows ($ in thousands):

	Interest Rate Shift in Basis Points
	- 100 bp			- 50 bp			Current			+ 50 bp			+ 100 bp
Total market value	$	3,316,040			3,264,359			3,211,755			3,159,039		$	3,106,806
Percent change in market value		3.2	%		1.6	%		—			(1.6	%)		(3.3	%)
Resulting unrealized appreciation / (depreciation)	$	(12,667	)		(64,348	)		(116,952	)		(169,668	)	$	(221,901	)

Foreign Currency Risk

     The Company writes business on a worldwide basis. Consequently, the Company’s principal exposure to foreign currency risk is its 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. The Company seeks to minimize its exposure to its largest foreign currency risks by holding invested assets denominated in foreign currencies to offset liabilities denominated in the same foreign currencies.

- 51 -

Sources of Fair Value

     The following table presents the carrying amounts and estimated fair values of the Company’s financial instruments as of June 30, 2006 ($ in thousands):

	Carrying
	Amount		Fair Value
Financial assets:
Fixed maturity securities	$	3,211,755	$	3,211,755
Preferred stocks		7,699		7,699
Other invested asset		5,000		5,000
Short-term investments		75,576		75,576
Financial liabilities:
Debt obligations	$	292,840	$	285,171

     The fair value of fixed maturity securities, preferred stocks and short-term investments are based on quoted market prices at the reporting date for those or similar investments. Other invested asset represents an investment in Inter-Ocean Holdings, Ltd., a non-public reinsurance company, and is carried at the estimated net realizable value. The Company has no ceded or assumed reinsurance business with Inter-Ocean Holdings, Ltd. The fair values of debt obligations are based on quoted market prices.

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 the design and operation 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 ensure 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 and accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding disclosures.

Changes in Internal Control over Financial Reporting

     Our management, including the Chief Executive Officer and the Chief Financial Officer, in connection with the evaluation required by Rules 13a-15 and 15d-15 under the Exchange Act, concluded that no changes occurred during the quarter ended June 30, 2006 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 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)	conducting operations in a competitive environment;
(2)	our ability to maintain our A.M. Best Company, Inc. rating;
(3)	significant weather-related or other natural or man-made disasters over which the Company has no control;
(4)	the effectiveness of our loss limitation methods and pricing models;
(5)	the adequacy of the Company’s liability for unpaid losses and loss adjustment expenses, including, but not limited to, losses from Hurricanes Katrina, Rita and Wilma and the possibility that estimates of losses and LAE from Hurricanes Katrina, Rita and Wilma may prove to be materially different from estimates made to date;
(6)	the availability of retrocessional reinsurance on acceptable terms;
(7)	our ability to maintain our business relationships with reinsurance brokers;
(8)	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;
(9)	the cyclicality of the property and casualty reinsurance business;
(10)	market volatility and interest rate and currency exchange rate fluctuation;
(11)	tax, regulatory or legal restrictions or limitations applicable to the Company or the property and casualty reinsurance business generally; and
(12)	changes in the Company’s plans, strategies, objectives, expectations or intentions, which may happen at any time at the Company’s 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 the Company. The foregoing factors, which are discussed in more detail in Item 1A – “Risk Factors” in the

- 53 -

Company’s Annual Report on Form 10-K for the year ended December 31, 2005 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.

TERMINATION ADDENDUM
EXCESS OF LOSS RETROCESSION AGREEMENT
BY AND BETWEEN
PLATINUM UNDERWRITERS BERMUDA, LTD.
(RETROCEDANT)

and

PLATINUM RE (UK) LIMITED
(RETROCESSIONAIRE)

     IT IS HEREBY MUTUALLY AGREED that effective December 31, 2005, this Agreement (“Agreement”), dated as of April 1, 2005, by and between Platinum Re UK Limited (the “Retrocessionaire”), and Platinum Underwriters Bermuda Ltd. (the “Retrocedant”), is Terminated.

However, this Article shall not apply where the loss has been incurred due (i) solely to the acts, or failure to act, of the Retrocedant in handling its claims or (ii) to fraud by a member of the Board of Directors or a corporate officer of the original reinsured acting individually or

The amount of the Retrocessionaires liability hereunder in respect of any loss or losses shall not be increased by reason of the inability of the Retrocedant to collect from any other Retrocessionaire, whether specific or general, any amounts which may have become due from them, whether such inability arises from the insolvency of such other Retrocessionaire or otherwise.

ARTICLE 13.  - NOTICE OF LOSS AND LOSS SETTLEMENTS

The Retrocedant shall advise the Retrocessionaire promptly of any Loss Occurrence which, in the opinion of the Retrocedant may result in a claim hereunder and of all subsequent developments thereto which, in the opinion of the Retrocedant may materially affect the position of the Retrocessionaire.

All loss settlements made by the Retrocedant, provided they are within the terms of this Agreement, shall be unconditionally binding upon the Retrocessionaire who agrees to pay all amounts for which it may be liable immediately upon being furnished by the Retrocedant with reasonable evidence of the amount due or to be due. In addition, the Retrocessionaire agrees to abide by court and/or arbitration decisions affecting the Retrocedant’s Original Reinsurance Contracts.

ARTICLE 14.  - ARBITRATION

All disputes and differences arising under or in connection with this Agreement shall be referred to arbitration under ARIAS Arbitration Rules.

The restrictions as outlined in this Article shall not apply to communication or disclosures that the Retrocessionaire is required to make to its statutory auditors, retrocessionaires, legal counsel, arbitrators involved in any arbitration procedures under this Agreement or disclosures required upon subpoena or other duly-issued order of a court or other governmental agency or regulatory authority.

ARTICLE 17.  - INSOLVENCY

In the event of the insolvency of the Retrocedant, this reinsurance shall be payable directly to the Retrocedant, or to its liquidator, receiver, conservator or statutory successor on the basis of the liability of the Retrocedant without diminution because of the insolvency of the Retrocedant or because the liquidator, receiver, conservator or statutory successor of the Retrocedant has failed to pay all or a portion of any claim.

It is agreed, however, that the liquidator, receiver, conservator or statutory successor of the Retrocedant shall give written notice to the Retrocessionaire of the pendency of a claim against the Retrocedant indicating the Reinsurance Contract reinsured, which claim would involve a possible liability on the part of the Retrocessionaire within a reasonable time after such claim is filed in the conservation or liquidation proceeding or in the receivership, and that during the pendency of such claim, the Retrocessionaire may investigate such claim and interpose, at its own expense, in the proceeding where such claim is to be adjudicated any defense or defenses that it may deem available to the Retrocedant or its liquidator, receiver, conservator or statutory successor. The expense thus incurred by the Retrocessionaire shall be chargeable, subject to the approval of the court, against the Retrocedant as part of the expense of conservation or liquidation to the extent of a pro rata share of the benefit which may accrue to the Retrocedant solely as a result of the defense undertaken by the Retrocessionaire.

As to all reinsurance made, ceded, renewed or otherwise becoming effective under this Agreement, the reinsurance shall be payable as set forth above by the Retrocessionaire to the Retrocedant or to its liquidator, receiver, conservator or statutory successor, except (1) where the Reinsurance Contracts specifically provide another payee in the event of the insolvency of the Retrocedant, or (2) where the Retrocessionaire with the consent of the insured or reinsureds, has assumed such Reinsurance Contract obligations of the Retrocedant as direct obligations of the Retrocessionaire to the payees under such Reinsurance Contracts and in substitution for the obligations of the Retrocedant to such payees.

ARTICLE 18.  - OFFSET

The Retrocedant and the Retrocessionaire shall have the right to offset any balance or amounts due from one party to the other under the terms of this Agreement.

ARTICLE 4 -  TERRITORY

Coverage applies within the territorial limits of Japan.

ARTICLE 5 - INURING REINSURANCE

It is understood and agreed that when the Retrocedant warrants that it is in the best interest of the Retrocedant and the Retrocessionaire, Retrocedant may purchase facultative reinsurance and/or any other treaty reinsurance.

All Reinsurance in place at April 1, 2006, or acquired after that date inures to the benefit of this program unless otherwise specified in Appendix 1.

ARTICLE 6 -  LIMIT AND RETENTION

The Retrocessionaire shall be liable in respect of each and every loss occurrence over and above an initial Ultimate Net Loss of $185,000,000 each and every loss each and every loss occurrence, subject to a limit of liability to the Retrocessionaire of $65,000,000 Ultimate Net Loss each and every loss or series of losses arising out of one loss occurrence. Nevertheless, the limit of liability to Retrocessionaire for all occurrences arising under this Agreement shall be limited to $130,000,000.

ARTICLE 7 -  REINSTATEMENT

Each loss hereon reduces the amount of indemnity provided under this Agreement by the amount paid. Any amount so exhausted shall be automatically reinstated from the time of the occurrence of loss and for each amount so reinstated, the Retrocedant agrees to pay an additional premium calculated at pro rata of the annual premium as respects the fraction of indemnity exhausted and 100% of the annual premium regardless of the unexpired term of this Agreement. Nevertheless, the Retrocessionaire’s liability shall not exceed $130,000,000 with respect to all Loss Occurrences during the term of the Agreement.

ARTICLE 8 - PREMIUM

The premium for this Agreement shall be a flat premium of $1,300,000 payable in two equal installments on April 1, 2006 and October 1, 2006.

ARTICLE 9 - ULTIMATE NET LOSS

Ultimate Net Loss shall mean the actual loss paid by the Retrocedant, or for which the Retrocedant becomes liable to pay, such loss to include 100% of any Extra Contractual Obligations and 100% of any Excess of Policy Limits loss, and expenses of litigation and interest, if any, and all other loss expenses covered under Original Reinsurance Contract, and such expenses of the Retrocedant incurred in the handling of loss arising out of Original Reinsurance Contracts including subrogation, salvage and recovery expenses (office expenses and salaries of officials and employees not classified as loss adjusters are not chargeable as expenses for purpose of this paragraph), but salvages and all

- 2 -

recoveries, including recoveries under all reinsurances which inure to the benefit of this agreement (whether recovered or not), shall be first deducted from such loss to arrive at the amount of liability attaching hereunder.

All salvages, recoveries or payments recovered or received subsequent to loss settlement hereunder shall be applied as if recovered or received prior to the aforesaid settlement and all necessary adjustments shall be made by the parties hereto.

For purposes of this article, the phrase “becomes liable to pay” shall mean the existence of a judgment or award, which the Retrocedant does not intend to appeal or a release has been obtained by the Retrocedant, or the Retrocedant has accepted a proof of loss.

Nothing in this clause shall be construed to mean that losses are not recoverable hereunder until the Retrocedant’s net loss has been ascertained.

ARTICLE 10 - EXTRA CONTRACTUAL OBLIGATIONS

This Agreement shall protect the Retrocedant and any original reinsured, within the limits hereof, where the loss includes any Extra Contractual Obligations. The term “Extra Contractual Obligations” is defined as those liabilities not covered under any other provision of this Agreement and which arise from the handling of any claim on business covered hereunder, such liabilities arising because of, but not limited to, the following: failure by any original reinsured to settle within the policy limit, or by reason of alleged or actual negligence, fraud, or bad faith in rejecting an offer of settlement or in the preparation of the defense or in the trial of any action against its insured or reinsured or in the preparation or prosecution of an appeal consequent upon such action.

The date on which any Extra Contractual Obligation is incurred by any original reinsured shall be deemed, in all circumstances, to be the date of the original disaster and/or casualty.

However, this Article shall not apply where the loss has been incurred due (i) solely to the acts, or failure to act, of the Retrocedant in handling its claims or (ii) to fraud by a member of the Board of Directors or a corporate officer of any original reinsured acting individually or collectively or in collusion with any individual or corporation or any other organization or party involved in the presentation, defense or settlement of any claim covered hereunder.

ARTICLE 11 - EXCESS OF ORIGINAL POLICY LIMITS

This Agreement shall protect the Retrocedant and any original reinsured, within the limits hereof, in connection with loss in excess of the limit of its original policy, such loss in excess of the limit having been incurred because of failure of the original reinsured to settle within the policy limit or by reason of alleged or actual negligence, fraud, or bad faith in rejecting an offer of settlement or in the preparation of the defense or in the trial of any action against its insured or reinsured or in the preparation or prosecution of an appeal consequent upon such action.

- 3 -

However, this Article shall not apply where the loss has been incurred due (i) solely to the acts, or failure to act, of the Retrocedant in handling its claims or (ii) to fraud by a member of the Board of Directors or a corporate officer of the original reinsured acting individually or collectively or in collusion with any individual or corporation or any other organization or party involved in the presentation, defense or settlement of any claim covered hereunder.

For the purpose of this Article, the word “loss” shall mean any amounts for which the original reinsured or Retrocedant would have been contractually liable to pay had it not been for the limit of the original policy.

ARTICLE 12 - NET RETAINED LINES

This Agreement applies only to that portion of any reinsurance or any Extra Contractual Obligations or Excess of Original Policy Limits which the Retrocedant retains net for its own account, and in calculating the amount of any loss hereunder and also in computing the amount or amounts in excess of which this Agreement attaches, only loss or losses in respect of that portion of any reinsurance or any Extra Contractual Obligations or Excess of Original Policy Limits which the Retrocedant retains nets for its own account shall be included.

The amount of the Retrocessionaire liability hereunder in respect of any loss or losses shall not be increased by reason of the inability of the Retrocedant to collect from any other Retrocessionaire, whether specific or general, any amounts which may have become due from them, whether such inability arises from the insolvency of such other Retrocessionaire or otherwise.

ARTICLE 13 - NOTICE OF LOSS AND LOSS SETTLEMENTS

The Retrocedant shall advise the Retrocessionaire promptly of any Loss Occurrence which, in the opinion of the Retrocedant may result in a claim hereunder and of all subsequent developments thereto which, in the opinion of the Retrocedant may materially affect the position of the Retrocessionaire.

All loss settlements made by the Retrocedant, provided they are within the terms of this Agreement, shall be unconditionally binding upon the Retrocessionaire who agrees to pay all amounts for which it may be liable immediately upon being furnished by the Retrocedant with reasonable evidence of the amount due or to be due. In addition, the Retrocessionaire agrees to abide by court and/or arbitration decisions affecting the Retrocedant’s Original Reinsurance Contracts.

ARTICLE 14 - ARBITRATION

          SECTION 14.01 As a condition precedent to any right of action under this Agreement, any dispute or difference between the parties hereto relating to the formation, interpretation, or performance of this Agreement, or any transaction under this Agreement, whether arising before or after termination, shall be submitted for decision to a panel of three arbitrators (the “Panel”) at the offices of Judicial Arbitration and

- 4 -

Mediation Services, Inc. in accordance with the Streamlined Arbitration Rules and Procedures of Judicial Arbitration and Mediation Services, Inc.

          SECTION 14.02 The party demanding arbitration shall do so by written notice to the responding party.

The arbitration demand shall state the issues to be resolved and shall name the arbitrator appointed by the demanding party.

          SECTION 14.03 Within thirty (30) days of receipt of the demand for arbitration, the responding party shall notify the demanding party of any additional issues to be resolved in the arbitration and the name of the responding party’s appointed arbitrator. If the responding party refuses or neglects to appoint an arbitrator within thirty (30) days following receipt of the written arbitration demand, then the demanding party may appoint the second arbitrator but only after providing ten (10) days’ written notice of its intention to do so, and only if such other party has failed to appoint the second arbitrator within such ten (10) day period.

          SECTION 14.04 The two arbitrators shall, before instituting the hearing, select an impartial arbitrator who shall act as the umpire and preside over the hearing. If the two arbitrators fail to agree on the selection of a third arbitrator within thirty (30) days after notification of the appointment of the second arbitrator, the selection of the umpire shall be made by the American Arbitration Association. Upon resignation or death of any member of the Panel, a replacement will be appointed in the same fashion as the resigning or deceased member was appointed. All arbitrators shall be active or former officers of property/casualty insurance or reinsurance companies, or Lloyd’s underwriters, and shall be disinterested in the outcome of the arbitration.

          SECTION 14.05 Within thirty (30) days after notice of appointment of all arbitrators, the Panel shall meet and determine timely periods for briefs, discovery procedures and schedules for hearings. The Panel shall have the power to determine all procedural rules for the holding of arbitration, including, but not limited to, the inspection of documents, examination of witnesses and any other matter relating to the conduct of the arbitration. The Panel shall interpret this Agreement as an honorable engagement and not as merely a legal obligation and shall make its decision considering the custom and practice of the applicable insurance and reinsurance business. The Panel shall be relieved of all judicial formalities and may abstain from following the strict rules of law. The decision of any two arbitrators shall be binding and final. The Panel shall render its decision in writing within sixty (60) days following the termination of the hearing. Judgment upon the award may be entered in any court of competent jurisdiction.

          SECTION 14.06 Each party shall bear the expense of its own arbitrator and shall share equally with the other party the expense of the umpire and of the arbitration.

- 5 -

          SECTION 14.07 Arbitration hereunder shall take place in New York, New York unless the parties agree otherwise.

          SECTION 14.08 The parties hereto hereby expressly (i) submit to the jurisdiction of the Panel, (ii) agree to comply with all requirements necessary to give the Panel jurisdiction and (iii) agree to abide by the final decision of the Panel.

          SECTION 14.09 This Article 14 shall survive termination of this Agreement.

ARTICLE 15 - CURRENCY

For purposes of this Agreement, where the Retrocedant receives premiums or pays losses in currencies other than United States dollars, such premiums or losses shall be converted into United States dollars at the actual rates of exchange at which these premiums or losses are entered in the Retrocedant’s books.

ARTICLE 16 - ACCESS TO RECORDS

The Retrocedant shall place at the disposal of the Retrocessionaire at all reasonable times, and the Retrocessionaire shall have the right to inspect through its designated representatives, during the term of this Agreement and thereafter, all books, records and papers of the Retrocedant in connection with any reinsurance hereunder, or the subject matter hereof.

The Retrocessionaire, except with the express prior written consent of the Retrocedant, shall not directly or indirectly, communicate, disclose or divulge to any third party, any knowledge or information that may be acquired either directly or indirectly as a result of the inspection of the Retrocedant’s books, records and papers. The restrictions as outlined in this Article shall not apply to communication or disclosures that the Retrocessionaire is required to make to its statutory auditors, retrocessionaires, legal counsel, arbitrators involved in any arbitration procedures under this Agreement or disclosures required upon subpoena or other duly-issued order of a court or other governmental agency or regulatory authority.

ARTICLE 17 - INSOLVENCY

In the event of the insolvency of the Retrocedant, this reinsurance shall be payable directly to the Retrocedant, or to its liquidator, receiver, conservator or statutory successor on the basis of the liability of the Retrocedant without diminution because of the insolvency of the Retrocedant or because the liquidator, receiver, conservator or statutory successor of the Retrocedant has failed to pay all or a portion of any claim.

It is agreed, however, that the liquidator, receiver, conservator or statutory successor of the Retrocedant shall give written notice to the Retrocessionaire of the pendency of a claim against the Retrocedant indicating the Reinsurance Contract reinsured, which claim would involve a possible liability on the part of the Retrocessionaire within a reasonable time after such claim is filed in the conservation or liquidation proceeding or in the

- 6 -

receivership, and that during the pendency of such claim, the Retrocessionaire may investigate such claim and interpose, at its own expense, in the proceeding where such claim is to be adjudicated any defense or defenses that it may deem available to the Retrocedant or its liquidator, receiver, conservator or statutory successor. The expense thus incurred by the Retrocessionaire shall be chargeable, subject to the approval of the court, against the Retrocedant as part of the expense of conservation or liquidation to the extent of a pro rata share of the benefit which may accrue to the Retrocedant solely as a result of the defense undertaken by the Retrocessionaire.

As to all reinsurance made, ceded, renewed or otherwise becoming effective under this Agreement, the reinsurance shall be payable as set forth above by the Retrocessionaire to the Retrocedant or to its liquidator, receiver, conservator or statutory successor, except (1) where the Reinsurance Contracts specifically provide another payee in the event of the insolvency of the Retrocedant, or (2) where the Retrocessionaire with the consent of the insured or reinsureds, has assumed such Reinsurance Contract obligations of the Retrocedant as direct obligations of the Retrocessionaire to the payees under such Reinsurance Contracts and in substitution for the obligations of the Retrocedant to such payees.

ARTICLE 18 - OFFSET

The Retrocedant and the Retrocessionaire shall have the right to offset any balance or amounts due from one party to the other under the terms of this Agreement. The party asserting the right of offset may exercise such right at any time whether the balances due are on account of premiums, losses or otherwise.

ARTICLE 19 - ERRORS AND OMISSIONS

Any inadvertent delay, omission, error or failure made in connection with this Agreement shall not relieve either party hereto from any liability which would attach hereunder if such delay, omission, error or failure had not been made, provided such delay, omission, error or failure is rectified as soon as reasonably practicable after discovery.

ARTICLE 20- MISCELLANEOUS PROVISIONS

          SECTION 20.01 Severability. If any term or provision of this Agreement shall be held void, illegal, or unenforceable, the validity of the remaining portions or provisions shall not be affected thereby.

          SECTION 20.02 Successors and Assigns. This Agreement may not be assigned by either party without the prior written consent of the other. The provisions of this Agreement shall be binding upon and inure to the benefit of and be enforceable by the parties hereto and their respective successors and assigns as permitted herein.

          SECTION 20.03 Execution in Counterparts. This Agreement may be executed by the parties hereto in any number of counterparts and by each of the parties hereto in separate counterparts, each of which counterparts, when so executed and

- 7 -

delivered, shall be deemed to be an original, but all such counterparts shall together constitute but one and the same instrument.

          SECTION 20.04 Headings. Headings used herein are not a part of this Agreement and shall not affect the terms hereof.

          SECTION 20.05 Amendments; Entire Agreement. This Agreement may be amended only by written agreement of the parties.

          SECTION 20.06 Negotiated Agreement. This Agreement has been negotiated at arm’s-length, and the fact that the initial and final drafts will have been prepared by either party will not give rise to any presumption for or against any party to this Agreement or be used in any respect or forum in the construction or interpretation of this Agreement or any of its provisions.
