(“Platinum US”), Platinum Re (UK) Limited, (“Platinum UK”), Platinum Underwriters Finance, Inc. (“Platinum Finance”), Platinum Regency Holdings, 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 nine months ended September 30,March 31, 2006 and 2005 and 2004 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 amended Annual Report on Form 10-K/A10-K for the year ended December 31, 2004.2005.
     The preparation of financial statements requires managementus 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.
     In November 2002, Platinum Holdings completed an initial public offering of 33,044,000 common shares (the “Initial Public Offering”). Concurrently with the Initial Public Offering, Platinum Holdings sold 6,000,000 common shares to The St. Paul Travelers Companies, Inc., formerly The St. Paul Companies, Inc., (“St. Paul”), and 3,960,000 common shares to RenaissanceRe Holdings Ltd. (“RenaissanceRe”) in private placements. St. Paul sold its 6,000,000 common shares in June 2004. As part of the Initial Public Offering, St. Paul and RenaissanceRe received options to purchase up to 6,000,000 and 2,500,000 additional common shares, respectively, at any time during the ten years following the Initial Public Offering at a price of $27.00 per share. Both St. Paul and RenaissanceRe have amended their options to provide that in lieu of paying $27.00 per share, any option exercise will be settled on a net share basis, which will result in Platinum Holdings issuing a number of common shares equal to the excess of the market price per share, determined in accordance with the amendments, over $27.00, less the par value per share, multiplied by the number of common shares issuable upon exercise of the option divided by that market price per share. Also, concurrently with the transactions in November 2002, the Company and 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 unpaid losses and loss adjustment expenses (“LAE”), unearned premiums and certain other liabilities on reinsurance contracts becoming effective in 2002. In addition to these transactions the Company issued Equity Security Units (“ESU’s”), consisting of a contract to purchase common shares of the Company in 2005 and an ownership interest in a senior note bearing interest at 5.25%, due 2007 issued by Platinum Finance, a U.S. based intermediate holding company subsidiary of Platinum Holdings, and guaranteed by Platinum Holdings (the “Senior Guaranteed Notes”).

Share-Based Compensation
     The CompanyWe 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.
     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” (“SFAS 123”) and Statement of Financial Accounting Standards No. 148 “Accounting for Stock-Based Compensation-Transition and Disclosure” (“SFAS 148”) effective January 1, 2003. SFAS 123 requires that. In accordance with the fair value of share options granted under the Company’s share option plan subsequent to the adoptiontransition rules of SFAS 148, be amortized into earnings over the vesting periods. The fair value of the share options granted is determined through the use of an option-pricing model. SFAS 148 provides transition guidance for a voluntary adoption of SFAS 123 and amends the disclosure requirements of SFAS 123. Prior to the adoption of SFAS 123, the Companywe elected to usecontinue using the intrinsic value method of accounting for itsour share-based awards granted to employees established by Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees” (“APB 25”) and continues to use the intrinsic method for share options granted in 2002. Under APB 25, if the exercise price of the Company’sour 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.
     Restricted shares awarded are amortized into earnings over the vesting period based on the fair value of the shares at the time of the grant. There are limits on the transferability of the restricted shares and such restricted shares may be forfeited in the event of certain types of termination of the recipient’s employment. The unearned or unvested portion of the restricted shares issued is presented as a separate component of shareholders’ equity.
     In December 2004, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 123R “Share-Based Payment” (“SFAS 123R”). SFAS 123R establishes standards for the accounting for transactions in which an entity exchanges its equity instruments for goods or services and for transactions in which an entity obtains employee services in share-based payment transactions. SFAS 123R requires that, prospectively, compensation costs be recognized for the fair value of all share options over the remaining vesting period, including the cost related to the unvested portion of all outstanding share options as of December 31, 2004. The share-based compensation expense for share options currently outstanding are to be based on the same cost model used to calculate the pro forma disclosures under SFAS 123. Consequently, the pro forma share-based compensation expense and pro forma income below approximates the expense under SFAS 123R.
The following table illustrates the effect on the Company’sour net income (loss) and earnings (loss) per share for the three and nine months ended September 30,March 31, 2005 and 2004 of applying the “fair value” method to all share option grants ($ in thousands, except per share data):

     On April 14, 2005, the Securities and Exchange Commission (“SEC”) adopted a new rule that allows SEC registrants to implement SFAS 123R as of January 1, 2006. The SEC’s new rule does not change the accounting required by SFAS 123R; it delays the date for compliance with the standard. Previously under SFAS 123R, the Company would have been required to implement the standard as of July 1, 2005.

     The CompanyWe routinely reviews itsreview 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 toto: the overall financial condition of the issuer, the length and magnitude of an unrealized loss, specific credit events, overall financial condition of the issuer, and the Company’sour ability and intent to hold a security for a sufficient period of time for the value to recover the unrealized loss. The Company’s ability to hold a securityThis is based on current and anticipated future positive cash flowflows from operations that generatesgenerate sufficient liquidity in order to meet itsour obligations. If the Company has determinedwe determine that an unrealized loss on a security is other than temporary, the Company writeswe write down the carrying value of the security and recordsrecord a realized loss in the statement of income.operations.
     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 March 31, 2006. Investment holdings within our corporate sector are diversified across approximately 30 sub-sectors, ranging from aerospace to telecommunications, and within each sub-sector across many individual issuers and issues. As of September 30, 2005 management believes thatMarch 31, 2006 there were 578 corporate issues in an unrealized loss position, with the Company’ssingle largest unrealized loss being $726,000. Investment holdings within the mortgage-backed and asset-backed sector are diversified across a number of sub-categories. As of March 31, 2006 there were a total of 997 issues in an unrealized loss position in our investment portfolio, doeswith the single largest unrealized loss being $802,000.
     Overall our unrealized loss position as of March 31, 2006 was a result of 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 containconsider any securities that have other-than-temporary impairments.of our available-for-sale investments to be other-than-temporarily impaired as of March 31, 2006.

In June 2005 as a result of the routine evaluation of investments, the Company wrote down the carrying value of the investment in Inter-Ocean Holdings Ltd. to its estimated net realizable value and recorded a realized loss of $769,000. The Company has no ceded or assumed reinsurance business with Inter-Ocean Holdings, Ltd.
(3)Hurricane Losses
     In 2005, two significant named hurricanes, Katrina and Rita (the “2005 Hurricanes”), caused severe damage in Louisiana, Mississippi, Texas and several other states in the Gulf Coast region of the United States. Hurricane Katrina, based on current industry estimates, is the costliest natural disaster in U.S. history. In 2004, four significant named hurricanes, Charley, Frances, Ivan and Jeanne (the “2004 Hurricanes”), caused severe damage in the Caribbean and the southeastern United States, principally Florida. As a result of losses arising from these catastrophic events, certain reinsurance contracts generated additional premiums and accrued profit commissions for certain reinsurance contracts were reduced.
     The net adverse impact on underwriting results of the Company for the three months ended September 30, 2005 and 2004 from the above mentioned hurricanes is summarized as follows ($ in thousands):
         
  2005  2004 
Gross losses and LAE $396,923  $186,457

(5)(4)Operating Segment Information
     The Company conducts itsWe 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 propertycatastrophe excess-of-loss treaties, per-risk excess-of-loss treaties propertyand proportional treaties and catastrophe excess-of-loss reinsurance treaties. The Casualty operating segment includes principally reinsurance treaties that cover umbrella liability, general and product liability, professional liability, directors and officers liability, workers’ compensation, casualty clash, automobile liability, surety and trade credit and surety.credit. This operating segment also includes accident and health reinsurance 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 the Company’sour operating segments, management useswe use measures such as underwriting income and underwriting ratios to evaluate segment performance. Management doesWe do not allocate by segment itsour assets or certain income and expenses such as investment income, interest expense and certain corporate expenses.

     We adopted SFAS 123R using the modified prospective method effective January 1, 2006. The cumulative effect of the adoption of SFAS 123R was not material.
     The fair value of each option grant in 2006 was estimated on the date of grant using the Black-Scholes option pricing model with the following assumptions:
Dividend yield1.06%
Risk free interest rate4.57%
Expected option life5.3 years
     The outstanding options are banded into groups for future forfeiture rate assumptions that ranged from 0% to 25%. The following summary sets forth option activity for the three months ended March 31, 2006 (amounts in thousands, except per share exercise price):

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
FOR THE THREE AND NINE MONTHS ENDED SEPTEMBER 30,MARCH 31, 2006 AND 2005 AND 2004
Business Overview
     Platinum Underwriters Holdings, Ltd. (“Platinum Holdings”) is a Bermuda holding company organized in 2002. Platinum Holdings and its subsidiaries (collectively, the “Company”) operate through 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 the Company’s amendedour Annual Report on Form 10-K/A10-K for the year ended December 31, 2004. The Company’s2005. Our consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”).
     In November 2002, Platinum Holdings completed an initial public offering of 33,044,000 common shares (“the Initial Public Offering”). Concurrently with the Initial Public Offering, Platinum Holdings sold 6,000,000 common shares to The St. Paul Travelers Companies, Inc., formerly The St. Paul Companies, Inc. (“St. Paul”), and 3,960,000 common shares to RenaissanceRe Holdings Ltd. (“RenaissanceRe”) in private placements. St. Paul sold its 6,000,000 common shares in June 2004. As part of the Initial Public Offering, St. Paul and RenaissanceRe received options to purchase up to 6,000,000 and 2,500,000 of additional common shares, respectively, at any time during the ten years following the Initial Public Offering at a price of $27.00 per share. Both St. Paul and RenaissanceRe have amended their options to provide that in lieu of paying $27.00 per share, any option exercise will be settled on a net share basis, which will result in Platinum Holdings issuing a number of common shares equal to the excess of the market price per share, determined in accordance with the amendments, over $27.00, less the par value per share, multiplied by the number of common shares issuable upon exercise of the option divided by that market price per share. Also, concurrently with the transactions in November 2002, the Company and 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 unpaid losses and loss adjustment expenses (“LAE”), unearned premiums and certain other liabilities on reinsurance contracts becoming effective in 2002. In addition to these transactions the Company issued Equity Security Units (“ESU’s”), consisting of a contract to purchase common shares of the Company in 2005 and an ownership interest in a senior note bearing interest at 5.25%, due 2007 issued by Platinum Underwriters Finance, Inc. (“Platinum Finance”), a U.S. based intermediate holding company subsidiary of Platinum Holdings, and guaranteed by Platinum Holdings (the “Senior Guaranteed Notes”).
     In May 2005, Platinum Finance issued $250,000,000 aggregate principal amount of the Series A 7.5% Notes due June 1, 2017 (the “Series A Notes”) unconditionally guaranteed by Platinum Holdings. The proceeds of the Series A Notes were used primarily to increase the capital of Platinum Bermuda and Platinum US.
     In September 2005, Platinum Holdings completed an offering of 5,839,286 of its common shares at a price to the public of $28.00 per share, less related expenses. The net proceeds to Platinum Holdings were approximately $161,865,000, and are expected to be used to make contributions to the capital and surplus of the reinsurance subsidiaries and for general corporate purposes. All shares were offered by Platinum Holdings and were sold pursuant to its effective shelf registration statement.

     The Company writesWe 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, directors and officers 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. The Company competes 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 the Company’s 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 significantly by volatile developments, including natural and other disasters,catastrophes, such as hurricanes, windstorms, earthquakes, floods, fires, explosions and other catastrophic events, including 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. AsTo the extent that actual claim liabilities are established to cover expected claims,higher than anticipated, the industry’s capacity to write new business diminishes. The industry is also affected by changes in the propensity of courts to expand insurance coverage and grant large liability awards, as well as by fluctuations in interest rates, inflation and other changes in the economic environment that affect market prices of investments.

-19-


     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. Rating agencies have increased capital requirement measures. As a result, a number of our competitors were downgraded. Following these events, some insurers and reinsurers raised capital through equity and debt offerings. Several new Bermuda based reinsurers have been formed. 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.

In 2005, two significant named hurricanes, Katrina and Rita (the “2005 Hurricanes”), caused severe damage in Louisiana, Mississippi, Texas and several other states in the Gulf Coast region of the United States. Hurricane Katrina, based on current industry estimates, is the costliest natural disaster in U.S. history. In 2004, four significant named hurricanes, Charley, Frances, Ivan and Jeanne (the “2004 Hurricanes”), caused severe damage in the Caribbean and the southeastern United States, principally Florida.

The 2005 Hurricanes were the primary cause of a declinedecrease in underwriting income of $144,999,000 in 2005 as compared with 2004. Partially offsetting the losses from the 2005 Hurricanes was profitable business in the Property and Marine segment as well as the Casualty segment.$12,486,000. Underwriting income in 2006 and 2005 and 2004 was also impacted by net favorable development that includes the net development of prior years unpaid losses and LAE and the related impact on premiums and profit commissions. Net unfavorable development was $1,246,000 in 2006, including $8,608,000 of net unfavorable development relating to the 2005 Hurricanes.

Net investment income increased in 2006 as compared with 2005 primarily due to increased invested assets and increased yields. The increase in invested assets is attributable to positive cash flow from operations in 2005the three months ended March 31, 2006 and 2004the year ended December 31, 2005 and the proceeds from the issuance of the Series A Notes.common and preferred shares and debt obligations in 2005.

Losses and LAE $206,774   237,698  $(30,924)
Loss and LAE ratios  60.1%  57.8% 2.3 points
     The decrease in losses and LAE in 2006 as compared with 2005 is due primarily to the decrease in net premiums earned in the Finite Risk and Casualty segments. The increase in the loss and LAE ratio is due primarily to net unfavorable loss development in 2006 as compared with net favorable loss development in 2005. Net unfavorable loss development was $4,359,000 representing 1.3% of net premiums earned in 2006 and net favorable loss development was approximately $15,862,000 representing 3.9% of net premiums earned in 2005. Net unfavorable loss development in 2006 includes $10,635,000 of net unfavorable development relating to the 2005 Hurricanes. Net favorable loss development in 2005 includes $4,784,000 of net unfavorable development relating to 2004 hurricane losses. Exclusive of loss development, the loss and LAE ratio is favorably affected by a shift in the mix of business. Net premiums earned and related losses and LAE have decreased predominantly 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 $69,239   93,249  $(24,010)
Acquisition expense ratios  20.1%  22.7% (2.6) 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 primarily in the Finite Risk segment and $628,000,is due to the decrease in finite casualty net premiums earned that had higher commission ratios. The decrease is also due to lower commissions on property contracts that were in force in 2005, have adjustable commissions and prior year catastrophe losses experience. Unfavorable development in prior year losses resulted in the reduction of profit commissions of $1,551,000 in 2006, representing 0.5% of net premiums earned. This compares with $3,078,000 of net reductions in profit commissions in 2005, representing 0.7% of net premiums earned.
     Operating expenses for the three months ended March 31, 2006 and 2005 were $22,988,000 and $20,008,000, respectively. Operating expenses include costs such as salaries, rent and like items related to reinsurance operations as well as costs associated with Platinum Holdings. Operating expenses in 2006 increased as compared with 2005 due to increased salaries and benefits, increased regulatory compliance costs and an increase in incentive-based compensation resulting from the adoption of the new share based compensation accounting standard.

Foreign currency exchange gains and losses result from the re-valuation into U.S. dollars of assets and liabilities denominated in foreign currencies. The CompanyWe periodically monitors itsmonitor our largest foreign currency exposures and purchasespurchase or sellssell foreign currency denominated invested assetscash and investments 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.

Losses and LAE $564,618   384,724  $179,894 
Losses and LAE ratios  131.5%  100.4% 31.1 points
     The increase in losses and LAE in 2005 as compared with 2004 is due primarily to losses from the 2005 Hurricanes. Losses and LAE in 2005 includes $154,383,000 more in losses and LAE from hurricanes as compared with 2004. The increase in losses and LAE in 2005 as compared with 2004 is also due to the increase in net premiums earned. The losses and LAE from the hurricanes in 2005 and 2004 were partially offset by favorable loss development of $42,066,000, representing 9.8% of net premiums earned in 2005 and $16,124,000, representing 4.2% of net premiums earned in 2004.

Acquisition expenses $98,858   81,271  $17,587 
Acquisition expense ratios  23.0%  21.2% 1.8 points
     The increase in acquisition expenses is due primarily to the increase in net premiums earned in 2005 as compared with 2004 as well as shifts in the mix of business. The increase in the acquisition expense ratio in 2005 as compared with 2004 is primarily in the Finite Risk segment and is due to shifts in the mix of business in the segment toward proportional casualty business that generally has higher acquisition costs. Acquisition costs include profit commissions of $4,423,000 in 2005, representing 1.0% of net premiums earned related to favorable loss development from prior years primarily in the Finite Risk segment. Profit commissions in 2004 related to favorable loss development from prior years were insignificant.
     Operating expenses for the three months ended September 30, 2005 and 2004 were $8,080,000 and $15,400,000, respectively. Operating expenses include costs such as salaries, rent and like items related to reinsurance operations as well as costs associated with Platinum Holdings. Operating expenses in 2005 decreased as compared with 2004 primarily due to greater reductions in incentive-based compensation accruals in 2005 as compared with 2004 due primarily to the 2005 Hurricanes.

Interest expense for the three months ended September 30,March 31, 2006 and 2005 was $5,450,000 and 2004 was $6,839,000 and $2,322,000, respectively, and includes interest related to the ESU’s as well as the Series A Notes.$2,173,000, respectively. The increase in 20052006 as compared with 2004 is due to interest on the Series A Notes issued in May 2005.
     Income tax benefit and the effective income tax rates for the three months ended September 30, 2005 and 2004 were as follows ($ in thousands):
             
  2005  2004  Increase 
Income tax benefit $(37,766)  (5,535) $(32,231)
Effective income tax rates  17.7%  7.4% 10.3 points
     The increase in income tax benefit in 2005 as compared with 2004 is due to the increase in net loss before income tax expense. The effective tax rate in 2004 was affected by an increase in the estimated annual effective tax rate in the three months ended September 30, 2004 due to the 2004 Hurricanes. A significant percentage of the losses and LAE from the 2004 Hurricanes was ceded by Platinum US to Platinum Bermuda where no income tax benefit was available. The effective income tax benefit rate in 2005 is higher as compared with 2004 as a result of two factors. Under existing internal reinsurance contracts, a lower percentage of losses and LAE from the 2005 Hurricanes was ceded in 2005 by Platinum US to Platinum Bermuda as compared with the percentage of losses and LAE from the 2004 Hurricanes ceded in 2004 and Platinum Bermuda retroceded $55,000,000 of its assumed losses and LAE in 2005 to Platinum UK. In addition,debt outstanding during the three months ended September 30,comparable periods. Interest expense in 2006 includes interest on the $250,000,000 of Series B 7.5% Notes due June 1, 2017, issued in May 2005 as well as interest on the estimated amountremaining balance of withholding tax related to the transfer from Platinum Finance to Platinum Holdings of the net proceeds from the issuance$42,840,000 of the Series AB 6.371% Remarketed Senior Guaranteed Notes, was decreased as a result of the net loss. Consequently, the estimate of the withholding tax was reduced by $1,000,000.
Nine Months Ended September 30, 2005 as Compared with the Nine Months Ended September 30, 2004
     Net income (loss) for the nine months ended September 30, 2005 and 2004 was as follows ($ in thousands):
             
  2005 2004 Decrease
Net income (loss) $(34,951)  34,861  $(69,812)
     The net loss in 2005 as compared with net income in 2004 is attributable to the 2005 Hurricanes, which caused significantly more damage than the 2004 Hurricanes. The 2005 Hurricanes were the primary cause of a decline of $111,377,000 in underwriting income in 2005 as compared with 2004. The aggregate adverse impact, net of tax, on net loss for the nine months ended September 30, 2005 from the 2005 Hurricanes was approximately $274,786,000 as compared with $144,809,000 from the 2004 Hurricanes. Partially offsetting the losses from the 2005 Hurricanes was profitable business in the Property and Marine segment as well as the Casualty segment. Underwriting income in 2005 and 2004 was impacted by net favorable development that includes the development of prior years unpaid losses and LAE and the related impact on premiums and profit commissions. Net favorable development was $67,212,000, representing 5.3% of net premiums earned in 2005, and $40,084,000, representing 3.9% of net premiums earned in 2004. Net income in 2005 as compared with 2004 was also impacted by an increase in investment income of $33,960,000, a decrease in operating expenses of $1,868,000, an increase in interest expense of $6,234,000, and a decrease in income tax expense of $20,884,000.
     Net premiums written and net premiums earned for the nine months ended September 30, 2005 and 2004 were as follows ($ in thousands):
             
  2005  2004  Increase

Net premiums earned $1,271,898   1,014,999  $256,899 

- 29 -


     The increase in net premiums written in 2005 as compared with 2004 is primarily attributable to growth in the Property and Marine and Casualty segments. The increases in Property and Marine and Casualty segments are partially offset by a decline in net premiums written in the Finite Risk segment. The increase in net premiums earned is related to the growth in current and prior periods’ net premiums written and is affected by changes in the mix of business and the structure of the underlying reinsurance contracts. In addition, net premiums written and earned in 2005 include $3,334,000 of net additional premiums relating to prior years.
     Net investment income for the nine months ended September 30, 2005 and 2004 was $92,250,000 and $58,290,000, respectively. Net investment income increased during 2005 primarily due to increased invested assets. The increase in invested assets is attributable to positive cash flow from operations in 2005 and 2004 and the proceeds from the issuance of the Series A Notes. Net cash flow from operations, excluding trading securities activities, was $573,215,000 and $610,144,000 for the nine months ended September 30, 2005 and 2004, respectively.

Net realized gains (losses) on investments were ($1,062,000) and $1,435,000 for the nine months ended September 30, 2005 and 2004, respectively. Net realized losses on investments in 2005 also include a provision of $769,000 for the permanent impairment of an investment in Inter-Ocean Holdings Ltd. included in other invested asset. Exclusive of this provision, net realized gains and losses on investments were the result of the Company’s efforts to manage the quality, diversity, currency exposure, duration and tax profile of the investment portfolio.
     Other income (expense) for the nine months ended September 30, 2005 and 2004 was ($201,000) and $2,137,000, respectively. Other income is comprised primarily of changes in fair value of fixed maturities classified as trading, net earnings on several reinsurance contracts in the Finite Risk segment that are accounted for as deposits and interest expense related to funds withheld. Other income for the nine months ended September 30, 2005 includes $128,000 of net unrealized gains relating to changes in fair value of fixed maturities classified as trading, $105,000 of earnings on reinsurance contracts accounted for as deposits and $434,000 of interest expense related to funds withheld. Other income for the nine months ended September 30, 2004 includes $220,000 of net unrealized gains relating to fixed maturities classified as trading, $565,000 of earnings on reinsurance contracts accounted for as deposits and a gain of $1,000,000 on the sale of assets.
     Net foreign currency exchange gains (losses) for the nine months ended September 30, 2005 and 2004 were ($1,870,000) and $326,000, respectively. Net foreign currency exchange gains and losses arise as a result of fluctuations in the amounts of assets and liabilities denominated in foreign currencies as well as fluctuations in the currency exchange rates.
     Losses and LAE and the resulting loss ratios for the nine months ended September 30, 2005 and 2004 were as follows ($ in thousands):

Losses and LAE $1,043,168   736,159  $307,009 
Loss and LAE ratios  82.0%  72.5% 9.5 points
     The increase in losses and LAE in 2005 as compared with 2004 is due primarily to losses from the 2005 Hurricanes that incurred losses and LAE of $154,383,000 more than the 2004 Hurricanes. The increase in losses and LAE in 2005 as compared with 2004 is also due to the increased net premiums earned. The losses and LAE from the hurricanes in 2005 and 2004 were partially offset by favorable loss development of $75,184,000, representing 5.9% of net premiums earned in 2005 and $44,653,000, representing 4.4% of net premiums earned in 2004.

Acquisition expenses $296,035   232,886  $63,149 
Acquisition expense ratios  23.3%  22.9% 0.4 points
     The increase in acquisition expenses is due primarily to the increase in net premiums earned in 2005 as compared with 2004. While the ratios in 2005 and 2004 are comparable, the ratios are affected by profit commissions, including approximately $4,638,000, representing .4% of net premiums earned in 2005 and $4,569,000, representing .5% of net premiums earned in 2004 relating to favorable loss development from prior years primarily in the Finite Risk segment.

Operating expenses include costs such as salaries, rent and like items related to reinsurance operations as well as costs associated with Platinum Holdings. Operating expenses in 2005 decreased as compared with 2004 primarily due to greater reductions in incentive-based compensation accruals in 2005 as compared with 2004 due primarily to the 2005 Hurricanes.

     The income tax benefitdecrease in 2005 as compared with income tax expense in 20042006 as compared with 2005 is due to the loss before income tax benefit in 2005. Thea lower effective income tax rate in 2005 is lower2006 as compared with 2004 as2005. The decrease in the effective tax rate is due primarily to a result of several factors. Under existing internal reinsurance contracts, a lowerhigher percentage of losses and LAE from the 2005 Hurricanes was ceded in 2005Company’s income before income taxes being generated by Platinum USBermuda, which is not subject to corporate income tax. In 2006, the combined net income derived from Platinum Holdings and Platinum Bermuda was approximately 79% of the total net income before tax expense as compared with the percentage of losses and LAE from the 2004 Hurricanes cededapproximately 63% in 2004 and Platinum Bermuda retroceded $55,000,000 of its assumed losses and LAE in 2005 to Platinum UK. Partially offsetting these factors is approximately $8,150,000 of income tax expense in 2005 associated with the transfer from Platinum Finance to Platinum Holdings of the proceeds from the issuance of the Series A Notes. This transaction is deemed to be a taxable distribution under U.S. tax law and subject to U.S. withholding tax.2005.

for the nine months ended September 30, 2005 and 2004 were 3.1% and 3.8%, respectively. The increases in operating costs and resulting other underwriting expense ratios are due to the increase in business as well as the allocation of a greater percentage ofless common operating and administrative costs allocated to the Casualty segment due to a decline in the underwriting activity in the Finite Risk segment. Partially offsetting these increases are greater reductions in incentive-based compensation accruals in 2005 as compared with 2004 due primarily to the 2005 Hurricanes.
     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 fundamentally the same asgenerally consistent with the classes covered by traditional products. Typically, the potential amount of losses paidwe might pay is finite or capped. In return for this limit on losses, there is typicallywe often accept a cap on the potential profit margin specified in the treaty. Profitstreaty and return profits above this margin are returned 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. We believe that the ongoing investigations by the SEC, the office of the Attorney General for the State of New York and the U.S. Attorney for the Southern District of New York and non-U.S. regulatory authorities such as the Bermuda Monetary Authority and the U.K. Financial Services Authority have significantly diminished demand for finite risk products. During the six months ended September 30, 2005 we did not write any new or renewal contracts in the segment. This operating segment generated 14.7%represented (18.5%) and 33.6%18.8% of the Company’sour net premiums written for the three months ended September 30,March 31, 2006 and 2005, respectively.

For this segment, because of the inter-relationship between losses and expenses, the Company believes it is more meaningful to evaluate the overall combined ratio, rather than its component parts of loss and acquisition expense ratios.

The remarketing was conducted on behalf of holders of the ESU’s and neither Platinum Holdings nor Platinum Finance received any cash proceeds from the remarketing. Proceeds from the remarketing were used to purchase a portfolio of U.S. Treasury securities to secure the obligations of the holders of the ESU’s under the related common share purchase contract and to pay the remarketing fee. There were no excess proceeds to be distributed to holders of the ESU’s in connection with the remarketing.

The Company has entered into agreements with several ceding companies that require it to provide collateral for its obligations under certain reinsurance contracts with these ceding companies under various circumstances, including where our obligations to these ceding companies exceed negotiated thresholds. These thresholds may vary depending on the Company’s rating from A.M. Best Company, Inc. (“A.M. Best”) or other rating agenciesthrough commercial banks and a downgrade of the ratings or a failure to achieve a certain rating may increase the amount of collateral the Company is required to provide. The Company may provide the collateral by delivering letters of credit to the ceding company, depositing assets into trusts for the benefit of the ceding companies or permitting the ceding companies to withhold funds that would otherwise be delivered to us under the reinsurance contract. The amount of collateral the Company is required to provide typically represents a portion of the obligations the Company may owe the ceding company, often including estimates of IBNR made by the ceding company.

     The payment of dividends and other distributions from the Company’s regulated reinsurance subsidiaries is limited by applicable laws and statutory requirements of the jurisdictions in which the subsidiaries operate, including Bermuda, the United States and the United Kingdom. Based on the regulatory restrictions of the applicable jurisdictions, the maximum amount available for payment of dividends or other distributions by the reinsurance subsidiaries of the Company as of September 30, 2005 without prior regulatory approval is estimated to be $114,637,000. While the Company’s reinsurance subsidiaries could legally pay such an aggregate amount, management believesspecial termination provisions that dividends in such an amount would reduce the capital of its reinsurance subsidiaries to a level that may result in a downgrade of its various ratings.

     Management believes that the cash flow generated by the operating activities of the Company’s subsidiaries will provide sufficient funds for the Company to meet its expected liquidity needs over the next twelve months. Beyond the next twelve months, cash flow available to the Company 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.

Economic Conditions
     Periods of moderate economic recession or inflation tend not to have a significant direct effect on the Company’s underwriting operations. Significant unexpected inflationary or recessionary periods can, however, impact the Company’s underwriting operations and investment portfolio.

Current Outlook
     BothHurricanes Katrina, Rita and Wilma (the “2005 Hurricanes”) caused significant losses to insurers and reinsurers experienced large losses from Hurricanes Katrina and Rita during the third quarterand fourth quarters of this year. In the weeks following2005. Following these events, some insurers andrating agencies strengthened the capital requirements for companies with catastrophe exposures. Many reinsurers raisedadded capital through a number of equity and debt offerings. Rating agencies have placed aofferings, 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 most of these companies were in the process of assembling their underwriting staff and establishing their market presence during the renewal season for contracts effective on January 1, 2006 (the “January 1 Renewal Season”). The January 1 Renewal Season is generally considered the most significant underwriting period of the year for the reinsurance industry.
     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 competitorsrenewed treaties improved or remained substantially unchanged depending on negative watchthe line of business. For reinsurance with exposures to North American hurricanes capacity has continued to shrink and rates have increased further since the potential for a ratings downgrade. TheJanuary 1 Renewal Season. We expect these conditions to continue during the remainder of 2006, but the competitive landscape is still evolving and the depth and breadth of market changes in reaction tofor the sizebalance of the hurricane losses is2006 remain uncertain. We expect that terms and conditions on most reinsurance treaties will improve or remain at the status quo and the degree of improvement will vary by line of business. The fourth quarter has the fewest number of contracts renewed of any quarter and has little impact on the premium recorded in the current year. We anticipate that our total net premiums written in 2005 will be approximately the same as in 2004.
     For the Property and Marine segment, underlying primary rates and reinsurance rates are expected to increase, particularly for risks exposed to Atlantic hurricanes. During 2006 we have achieved average rate increases of over 50% on our U.S. wind-exposed risks.property renewal business and nearly 10% on our non-U.S. property renewal business, as well as average rate increases of approximately 65% 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.
     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 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, given the large size of the Hurricane Katrina loss many reinsurersas revisions to catastrophe models are released and new rating agency capital requirements are better understood, there will be reevaluating the adequacy of their pricing models. We also believe that reinsurance buyers will consider securing more coverage in the future, especially if the losses from Hurricane Katrina have exceeded the limits of their in-force programs. We further believe that the reduction in supplycontinued U.S. market hardening for property and increased demand means higher market pricing will result despite the significant post-event capital raising. We believe that other catastrophe-exposed lines of business will also experience rate increases though to a smaller degree. We anticipate that our net premiums written in 2005 in this segment will be approximately the same as in 2004.marine business.

     For the Casualty segment, we believe that losses from the size of the Hurricane Katrina losses2005 Hurricanes and enhanced rating agency capital requirements will cause the primarycertain insurance and reinsurance companies and reinsurers to review their strategies for business which is not generally exposed to catastrophes. During 2006, ceding companies were willing to increase retentions and their appetitereinsurers competed for growthparticipation on the best treaties. However, rates stabilized in thesecertain lines of business resultingwhere they had been declining. As a result, we believe that the business underwritten during 2006 has approximately the same level of expected profitability as the business we wrote during the comparable period in a stabilizing effect on profitability.2005. We have written more commercial liability and less professional liability, trade credit, accident and health and clash business. 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 believe that our rating, capitalization and reputation as a lead casualty reinsurer positions us well to write profitable opportunitiesbusiness as theythe opportunities arise. We expect these conditions to persist through 2006 and that the casualty market will remain attractive. However, two areas where pricing has generally fallen below our standards are accident and health and trade credit and accordingly we anticipate thatsignificantly cutting back our net premiums writtenwritings in 2005 in this segment will be higher than in 2004.these lines.
     In the Finite Risk segment, we expectbelieve that the ongoing investigations by the SEC, the office of the Attorney General for the State of New York, and the U.S. Attorney for the Southern District of New York and non-U.S. regulatory authorities such as the Bermuda Monetary Authority and the U.K. Financial Services Authority willresulted in significantly diminishdiminished demand for limited risk transfer products in 2005. 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 short term.comparable period last year. Although we cannot predictexpect the ultimate outcomerelatively low level of these investigations, we believe that if the buyers and sellers of these products perceive that the accounting, headline and regulatory risk has receded, demand will return. Also, improved or stabilized pricing in traditional lines of business may mean fewer companies devoting significant resourcescontinue during 2006, there are signs that buyers are, once again, considering finite reinsurance as a solution to finite lines. Accordingly, we expect to write significantly less finite business in 2005 than in 2004. During the six months ended September 30, 2005 we did not write any new or renewal contracts in our Finite Risk segment and we anticipate that our net premiums written in 2005 in this segment will be significantly lower than in 2004.

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 at the financial reporting date and throughout the relevant periods.disclosures. Certain of the estimates and assumptions result from judgments that can beare necessarily subjective and complex, and consequently actual results may differ from these estimates. The Company’s most critical accounting policies involve premiums written and unearned premium,earned, unpaid losses and LAE, reinsurance, investments, income tax expensetaxes and share-basedstock-based compensation. The critical accounting policies presented herein are also discussed in more detail in the notes to the consolidated financial statements included in the Company’s amended Annual Report on Form 10-K/A10-K for the year ended December 31, 2004.2005.
     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 income,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

-31-


contract disruptions. In addition to estimating WBNR, the Company estimates the portion of premiumpremiums 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. The net impact on the results of operations of changes in estimated premiums is reduced by the losses and acquisition expenses related to such premiums.
     When estimating premiums written and earned, each of the Company’sour 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’’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 the Company’sour 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.
     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 March 31, 2006 of $517,429,000 include $483,313,000 of WBNR that is based upon estimates. The appropriateness of the premium estimatesWBNR is evaluated in light of the actual premium reported by the ceding companies and any adjustments to these estimatesWBNR 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 the Company’sour underwriting function in respect of the ninethree months ending September 30, 2005ended March 31, 2006 were reviewed based upon the foregoing considerations.evaluated. The cumulative impact of this reviewour evaluation in respect of premiums receivable as of March 31, 2006 was to reduce the estimateWBNR by approximately $43,841,000$60 million or 7.9%12%.

As an illustration, the Company had one contractMarch 31, 2006 and reflects a $30 million reduction from initial premium estimates. We believe that at September 30, 2005, represented approximately $49,255,000 in premiums receivable. With respect to that contract, the Company reduced premiums receivable by approximately $3,600,000 because it did not expect the ceding company to meet its production estimates or to achieve its estimated rate increases. The Company believes that itwe reasonably could have made an adjustment of between $0 and $3,600,000$30 million with respect to that contractthis reinsurance class at September 30, 2005.March 31, 2006.

likely. Premiums receivable under a particular contract can vary significantly from estimates derived from the Company’s underwriting function depending upon its assessment of the production and rate changes likely to be achieved by the ceding company.     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. Earned premiums,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 March 31, 2006, we did not establish an allowance 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.
     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 earned immediately.immediately earned. An allowance for uncollectible premiums is established for possible non-payment of such amounts due, as deemed necessary.

     Unpaid Losses and LAE
     TheOne of the most significant judgmentjudgments 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 (“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. The Company’sCompany 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 includerepresent 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 costdegree 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 were reported but not yet paid (“case reserves”)the Company underwrites and the costvarying reserving practices among ceding companies, the Company’s reserve estimates are highly dependent on management judgment and are therefore uncertain. Estimates of claims thatunpaid 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 March 31, 2006 for unpaid losses and LAE were incurred but not reported (“IBNR”).$2,371,916,000. The following table sets forth a breakdown between case reserves and IBNR by segment at March 31, 2006 ($ in thousands):
                 
  Property          
  and Marine  Casualty  Finite Risk  Total 
Case reserves $425,284   188,709   81,378  $695,371 
IBNR  407,842   994,019   274,684   1,676,545 
             
Total unpaid losses and LAE $833,126   1,182,728   356,062  $2,371,916 
             
     Case reserves are usually based upon claim reports received from ceding companies. The information the Company receiveswe receive varies by ceding company and may include paid losses, estimated case reserves, and an estimated provision for IBNR reserves. Case reserves may be increased or reduced by the Company’sour 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 the Company’sour estimated exposure to an industry loss and may include the use of catastrophe modeling software.
     When estimating unpaid losses and LAE, each of the Company’s 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.
     The gross liabilities recorded on the Company’s balance sheet as of September 30, 2005 for unpaid losses and LAE were $2,079,668,000. The following table sets forth a breakdown between case reserves and IBNR by segment at September 30, 2005 ($ in thousands):

- 46 -


                 
  Property          
  and Marine  Casualty  Finite Risk  Total 
Case reserves $130,159   139,835   29,557  $299,551 
IBNR  620,617   868,619   290,881   1,780,117 
             
Total unpaid losses and LAE $750,776   1,008,454   320,438  $2,079,668 
             
     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 (“reported losses”) are subtracted from expected ultimate losses to determine IBNR. The initial expected ultimate losses involve management judgment and are based on: (i) contract by contract expected loss ratios derived from the Company’sour pricing process, and (ii) historical loss ratios of the Company and of the reinsurance underwriting segment of St. Paul (“St. Paul Re”) prior to the Initial Public OfferingRe adjusted for rate changes and trends. These judgments will take into account management’s view of past, current and futurefuture: (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 the Company’sour 80 classes of coverage for each Underwriting Year. The Company doesWe do not believe that these multiple point estimates are or should be considered a range. The Company’sOur actuaries look atconsider 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 the Company’sour 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 Accidentaccident and Healthhealth class within the Casualty segment. Once theour actuaries make their determinations of the most appropriate point estimate for each class, this information is aggregated and presented toreviewed and approved by executive management for review and approval.management. At September 30, 2005March 31, 2006 the liability for unpaid losses and LAE that the Companywe recorded reflectedincludes the point estimates of IBNR prepared by the Company’sour actuaries.
     Generally, North American casualty excess business has the longest pattern of reported losses and, therefore, the greatest uncertainty.loss estimates have a higher degree of uncertainty than other reinsurance classes. IBNR for these classes at September 30, 2005March 31, 2006 was $643,000,000$749 million which was 36%47% of the total IBNR for the Company at that date. Because estimates of unpaid losses and LAE related to North American casualty excess business has the greatesthave a higher degree of uncertainty, the Companywe 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 65% to 70% would result in an increase of the IBNR for these classes of $56,000,000.by $68.5 million. This equates to approximately 8% of the liability for total unpaid losses and LAE for these classes at September 30, 2005.March 31, 2006. As another example, if the estimated pattern of reported losses was accelerated by 5% the IBNR for these classes would decrease by $3,000,000$3 million which is less than 1%. Because the Company believesWe 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 Company has selected these two inputs as the basis for the sensitivity analyses in this paragraph.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 reported 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 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.
     While the Company commenced operations in 2002, the business written is sufficiently similar to the historical business of St. Paul Re that the Company uses the historical loss experience of this business 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 to 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 involves a catastrophe occurrence that affects many ceding companies. Ultimate losses and LAE are based on management’s judgment that reflects estimates gathered from ceding companies, estimates of insurance industry losses gathered from public sources and estimates from catastrophe modeling software.
     Estimated amounts recoverable from retrocessionaires on unpaid losses and LAE are determined based on the Company’s estimate of ultimate losses and LAE and the terms and conditions of its retrocessional contracts. These amounts are reflected as assets.
     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, such as the judicial interpretations of what constitutes a covered loss under insurance and reinsurance contracts. 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’s judgment.
     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 directors and officers liability and automobile liability, where information, such as required medical treatment and costs for bodily injury claims, only emerges over time. In the overall loss reserving process, provisions for economic inflation and changes in the social and legal environment are considered.
     The losses caused by Hurricane Katrina include significant flood damage, most of which are not covered by the Company’s reinsurance contracts or its ceding companies’ insurance policies. The Company’s estimate of losses from the hurricanes does not include losses excluded from coverage. There are a number of challenges to flood loss exclusions, including actions taken by the Mississippi attorney general and class action litigation. While flood coverage exclusions have generally been upheld by courts, there can be no assurance that significant additional losses will not arise as a result of claims for losses excluded from coverage by contract.

Loss reserve calculations for directprimary 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 directprimary 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 a 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 March 31, 2006, we did not have any significant back-log related to our processing of assumed reinsurance information.
     Since the Company relieswe rely on information regarding paid losses, case reserves and IBNR reserves provided by ceding companies in order to assist the Companyus in estimating its ownour liability for unpaid losses and LAE, the Company maintainswe 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 managing reported claims and conferring with ceding companies or brokers on claims matters, the Company’sour claims personnel conduct periodic audits of specific claims and the overall claims procedures of itsour ceding companies at their offices. The Company reliesWe rely on itsour 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.
     EstimatesIn addition to the inherent uncertainty of estimating unpaid losses and LAE, our estimates with respect to the 2005 Hurricanes are periodically re-estimatedsubject to an unusually high level of uncertainty arising out of complex and adjustedunique causation and coverage issues associated with the attribution of losses to wind or flood damage or other perils such as new information becomes available. Any such adjustments are accountedfire, 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 as changes inthe 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 are reflected in results of operations in the period in which they are made.may be influenced by evolving legal and regulatory developments.

     As of September 30, 2005, the Company did not have any significant back-log related to its processing of assumed reinsurance information.
     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. Evaluating riskRisk transfer involvesanalysis 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 significantsufficient insurance risk are generally accounted for as reinsurance deposit liabilities with interest expense charged to other income and credited to the liability.
     Investments
     In accordance with the Company’sour investment guidelines, investments consist largelyour investment portfolio consists of high-grade marketablediversified, high quality, predominantly publicly traded fixed incomematurity securities. Fixed maturities owned that the Companymaturity 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 maturities owned that the Company hasmaturity 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.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 foreign 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.

     The Company believes it hasWe believe we have the ability to hold any specific security to maturity. This is based on current and anticipated future positive cash flow from operations that generatesis expected to generate sufficient liquidity in order to meet itsour 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“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 lengthoverall financial condition of the issuer, the duration and magnitude of an unrealized loss, specific credit events the overall financial condition of the issuer, and the Company’s 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 income.operations.

     Platinum Holdings and Platinum Bermuda are incorporateddomiciled 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.

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
     EffectiveWe adopted Statement of Financial Accounting Standards No. 123R “Share-Based Payment” (“SFAS 123R”) on the modified prospective method effective January 1, 2003,2006. SFAS 123R establishes standards for the Company adoptedaccounting 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” (“SFAS 123”) and Statement of Financial Accounting Standards No. 148 “Accounting for Stock-Based Compensation-Transition and Disclosure” (“SFAS 148”). SFAS 123 requires thatIn accordance with the fair value of shares granted under the Company’s share option plan subsequent to adoptiontransition rules of SFAS 148, be amortized in earnings over the vesting periods. The fair value of the share options granted is determined through the use of an option-pricing model. SFAS 148 amends SFAS 123 and provides transition guidance for a voluntary adoption of FAS 123 as well as amends the disclosure requirements of SFAS 123. For the period from November 1, 2002 through December 31, 2002, the Company usedwe elected to continue using the intrinsic value method of accounting for stock-basedour 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 the Company’sour 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. For share options granted in 2002, the Company continues to use APB 25.
     In December 2004, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 123R “Share-Based Payment” (“SFAS 123R”). SFAS 123R establishes standards for the accounting for transactions in which an entity exchanges its equity instruments for goods or services and for transactions in which an entity obtains employee services in share-based payment transactions.

SFAS 123R requires that, prospectively, compensation costs be recognized for the fair value of all share options over the remaining vesting period, including the cost related to the unvested portion of all outstanding share options as of December 31, 2004. The share-based compensation expense for share options currently outstanding are to be based on the same cost model used to calculate the pro forma disclosures under SFAS 123.
     On April 14, 2005, the SEC adopted a new rule that allows SEC registrants to implement SFAS 123R as of January 1, 2006. The SEC’s new rule does not change the accounting required by SFAS 123R; it delays the date for compliance with the standard. Previously under SFAS 123R, the Company would have been required to implement the standard as of July 1, 2005. Consequently, the Company’s consolidated financial statements filed with the SEC do not need to comply with SFAS 123R until January 1, 2006. The Company plans to adopt the provisions of the SFAS 123R in the first quarter of 2006.
Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Market and Credit Risk
     The Company’s principal invested assets are fixed maturities,maturity securities, which are subject to fluctuationsthe risk of potential losses from adverse changes in market value associated with changes in interest 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 limit its credit risk by placingplace its investments in high quality credit issues and to limit the amount of credit exposure with respect to any one issuer or industry.asset class. The Company also selects investments with characteristics such as duration, yield, currency and liquidity to reflect, in the amount and payment timing riskaggregate, the underlying characteristics of itsour unpaid losses and LAE and its expected cash flow from operations.LAE. The Company attempts to manage itsminimize 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 September 30, 2005,March 31, 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 premiums receivable,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 premiumspremium receivable. Management does not considerTo mitigate credit risk related to its retrocessionaires to be material as of September 30, 2005. Management considersour reinsurance recoverable amounts, we consider the financial strength of our retrocessionaires when determining whether to purchase coverage from them. Retrocessional coverage is generally obtained from companies rated “A”“A-” or better by A. M. Best unless the retrocessionaires’retrocessionaire’s obligations are fully collateralized. For exposures where losses become known and are paid in a relatively short period of time, we may obtain retrocessional coverage from companies rated “A-” or better by A. M. Best. The financial performance and rating status of all material retrocessionaires is routinely monitored.
     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. Further,Conversely, in certain jurisdictions, when ceding companies remit premiums for such contracts are paid to reinsurance brokers, for payment over to the Company, such premiums will beare deemed to have been paid to the Company and the ceding company will

is no longer be 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 paymentpremium 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 incomematurity portfolio and can cause changes in the actual timing of receipt of certain principal payments. Rising interest rates result in a declinedecrease in the market value of our fixed incomematurity 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 extension risk. Conversely, a decline in interest rates will result in a rise in the market value of fixed income portfolio and can expose the portfolio, in particular our mortgage-backed securities, to prepayment risk. The approximate aggregate hypothetical impact on theour fixed incomematurity portfolio, generated from an immediate parallel shift in the treasury yield curve, as of September 30, 2005March 31, 2006 is as follows ($ in thousands) :

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 foreign currencies. The Company measures its liabilities, including those denominated in foreign currencies, on a quarterly basis. The timing of the evaluation and determination of foreign currency denominated liabilities and the investment of assets in the same foreign currency also presents an element of foreign currency risk.currencies.

PART II OTHER INFORMATION
Item 1. LEGAL PROCEEDINGS
     As previously disclosed, in November and December 2004, the Company received subpoenas from the SEC and the Office of the Attorney General for the State of New York for documents and information relating to certain non-traditional, or loss mitigation, insurance products. The Company is fully cooperating in responding to all such requests. Other reinsurance companies have reported receiving similar subpoenas and requests. This investigation appears to be at an early stage and, accordingly, it is not possible to predict the direction the investigation will take and the impact, if any, it may have on the Company’s business. In view of the ongoing industry investigations, the Company retained the law firm of Dewey Ballantine LLP to conduct a review of its finite reinsurance practices. They informed the Company that they identified no evidence of improprieties.
     On June 14, 2005, we received a grand jury subpoena from the United States Attorney for the Southern District of New York requesting documents relating to our finite reinsurance products. We have been informed that other companies in the industry have received similar subpoenas. We are fully cooperating in responding to this request.
     In the normal course of business, the Company may become involved in various claims and legal proceedings. The Company is not currently aware of any pending or threatened material litigation.
Item 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS
     During the third quarter of 2005, there were no sales of equity securities of the Company not registered under the Securities Act. Also, during the third quarter of 2005, neither the Company nor any affiliated purchaser purchased any of the Company’s common shares.
