              PLATINUM UNDERWRITERS HOLDINGS, LTD. AND SUBSIDIARIES
        Notes to Condensed Consolidated Financial Statements (Unaudited)
            For the Three and Six Months Ended June 30, 2004 and 2003

NOTE 1 BASIS OF PRESENTATION

      The condensed consolidated financial statements have been prepared in
conformity with accounting principles generally accepted in the United States of
America ("U.S. GAAP") and include the accounts of Platinum Underwriters
Holdings, Ltd. and its subsidiaries (the "Company"), including Platinum Re (UK)
Limited, Platinum Underwriters Bermuda, Ltd., Platinum Underwriters Reinsurance,
Inc., Platinum Underwriters Finance, Inc., Platinum Regency Holdings, and
Platinum Administrative Services, Inc. All material inter-company transactions
have been eliminated in preparing these consolidated financial statements. The
condensed consolidated financial statements included in this report as of and
for the three and six months ended June 30, 2004 and 2003 are unaudited and
include those adjustments, consisting of normal recurring items that management
considers necessary for a fair presentation under U.S. GAAP. These consolidated
financial statements should be read in conjunction with the consolidated
financial statements and related notes included in the Company's Annual Report
on Form 10-K for the year ended December 31, 2003.

      The preparation of financial statements requires management 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 Underwriters Holdings, Ltd. ("Platinum
Holdings") completed an initial public offering of 33,044,000 common shares.
Concurrent with the 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. In addition to the common
shares issued, the Company issued Equity Security Units, consisting of a
contract to purchase common shares in 2005 and an ownership interest in a senior
note due 2007. Also, concurrent with these transactions, 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 (the "Quota Share Retrocession
Agreements").

Share Based Compensation

      During 2003, the Company adopted 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 that the fair value of share options granted under the
Company's share option plan subsequent to the adoption 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 transitioning guidance for a voluntary adoption of
FAS 123 as well as amends the disclosure requirements of SFAS 123. Prior to the
adoption of SFAS 123, the Company elected to use the intrinsic value method of
accounting for its 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's 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.

      Had the Company calculated and recorded compensation expense for all share
option grants based on the "fair value" method described in SFAS 123, net income
and earnings per share, net of tax, would have been the pro forma amounts for
the three and six months ended June 30, 2004 and 2003 as indicated below ($ in

NOTE 4 OPERATING SEGMENT INFORMATION

      The Company conducts its worldwide reinsurance business through three
operating segments: Property and Marine, Casualty and Finite Risk. The Property
and Marine operating segment includes principally property and marine
reinsurance coverages that are written in the United States and international
markets. This business includes property per-risk excess-of-loss treaties,
property 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, trade credit and surety. This 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 Company focuses on providing such clients with customized solutions for
their financial management needs.

      In managing the Company's operating segments, management uses measures
such as underwriting income and underwriting ratios to evaluate segment
performance. Management does not allocate by segment its assets or certain
income and expenses such as investment income, interest expense and certain
corporate expenses. Segment underwriting income is reconciled to income before
income taxes. The measures used by management in evaluating the Company's
operating segments should not be used as a substitute for measures determined
under U.S. GAAP. The following table summarizes underwriting activity and ratios
for the operating segments together with a reconciliation of underwriting income
to income before income taxes for the three and six months ended June 30, 2004
and 2003 ($ in thousands):

NOTE 5 SHELF REGISTRATION STATEMENT AND SALE OF COMMON SHARES BY ST. PAUL

      The Company has filed an unallocated universal shelf registration
statement with the Securities and Exchange Commission ("SEC"), which the SEC
declared effective on April 5, 2004. The securities registered under the shelf
registration statement for possible future sales include up to $750,000,000 of
common shares, preferred shares and various types of debt securities. The
registration statement also includes common shares held by St. Paul and
RenaissanceRe and common shares issuable upon exercise of options owned by St.
Paul and RenaissanceRe. On June 25, 2004, the Company announced St. Paul's
intent to sell 6,000,000 of the Company's common shares in an underwritten
public offering, which was effected pursuant to a prospectus supplement to the
shelf registration statement dated June 28, 2004 and completed on June 30, 2004.
The Company did not sell any common shares in the offering and did not receive
any proceeds from the sale of the common shares by St Paul. St. Paul continues
to hold an option to acquire 6,000,000 common shares of the Company. The
6,000,000 common shares sold by St. Paul amounted to $177,330,000 of the
securities registered under the $750,000,000 shelf registration statement.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS
        FOR THE THREE AND SIX MONTHS ENDED JUNE 30, 2004 AND 2003

BUSINESS OVERVIEW

      Platinum Underwriters Holdings, Ltd. ("Platinum Holdings") is a Bermuda
holding company organized in 2002. Platinum Holdings and its subsidiaries (the
"Company") operate through three licensed reinsurance subsidiaries: Platinum
Underwriters Reinsurance, Inc. ("Platinum US"), Platinum Re (UK) Limited
("Platinum UK") and Platinum Underwriters Bermuda, Ltd. ("Platinum Bermuda").
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 Annual Report on Form 10-K for the year ended December
31, 2003. The Company's 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. Concurrent with the 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. In
addition to the common shares issued, the Company issued Equity Security Units,
consisting of a contract to purchase common shares in 2005 and an ownership
interest in a senior note due 2007. Also, concurrent with these transactions,
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 (the "Quota Share Retrocession
Agreements").

      The Company writes 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 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. Large financial institutions
represent some of the Company's competitors, while others are specialty
reinsurance companies. Financial institutions have also created alternative
capital market products that compete with reinsurance products, such as
reinsurance securitization. The Company's principal

                                     - 13 -


competitors vary by type of business. Bermuda-based reinsurers are significant
competitors on property catastrophe business. Lloyd's of London syndicates are
significant competitors on marine business. On international business, the large
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 affected
significantly by volatile developments, including natural and other disasters,
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. As
liabilities are established to cover expected claims, the industry's capacity to
write new business diminishes. The industry is also affected by changes in the
propensity of courts to expand insurance coverage and grant large liability
awards, as well as fluctuations in interest rates, inflation and other changes
in the economic environment that affect market prices of investments.

RESULTS OF OPERATIONS

      Three Months Ended June 30, 2004 as Compared with the Three Months Ended
June 30, 2003

      Net income for the three months ended June 30, 2004 and 2003 was as
follows ($ in thousands):



                       Three Months Ended June 30,
                       ---------------------------           Increase
                         2004                2003           (decrease)
                       --------             ------         ----------
                                                  
Net income             $ 49,799             26,605          $ 23,194


      The 87% increase in net income in 2004 as compared with 2003 is primarily
attributable to an increase in investment income of $5,946,000, a charge for
$9,400,000 in 2003 for the payment to and share option expense of the Company's
former chief executive, a decline in foreign currency exchange losses of
$3,568,000 and a reduction in the effective income tax rate in 2004 as Platinum
Bermuda provides an increasing proportion of income before income taxes.

      Net premiums written and net premiums earned for the three months ended
June 30, 2004 and 2003 were as follows ($ in thousands):



                             Three Months Ended June 30,
                             ---------------------------        Increase
                                2004               2003        (decrease)
                             ---------           -------       ----------
                                                      
Net premiums written         $ 330,527           307,243        $  23,284
Net premiums earned          $ 310,867           279,376        $  31,491


      The increase in net premiums written in 2004 as compared with 2003 is
primarily in the Property and Marine segment. The increase in net premium 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.

      Net investment income for the three months ended June 30, 2004 and 2003
was $19,377,000 and $13,431,000, respectively. Net investment income increased
in 2004 primarily due to increased invested assets attributable to positive cash
flow from operations, exclusive of trading securities activities, of
$191,769,000 during 2004. Net investment income for the three months ended June
30, 2003 included $1,357,000 of interest received from St. Paul on balances due
relating to the Quota Share Retrocession Agreements. Net realized gains (losses)
on investments of ($1,279,000) and $519,000 for the three

                                     - 14 -


months ended June 30, 2004 and 2003, respectively, were the result of investment
sale activity to manage the credit quality and duration of the investment
portfolio and to increase investments in municipal bonds.

      Other income for the three months ended June 30, 2004 and 2003 was $
605,000 and $2,749,000, respectively. Other income includes net earnings on a
small number of reinsurance contracts in the Finite Risk segment accounted for
as deposits. Other income in the three months ended June 30, 2004 also includes
$727,000 of net unrealized losses relating to changes in the fair value of
approximately $51 million of fixed maturities classified as trading at June 30,
2004 and a gain of $1,000,000 on the sale of assets. There were no fixed
maturities classified as trading and no unrealized gains or losses included in
other income for the three months ended June 30, 2003.

      Net foreign currency exchange losses for the three months ended June 30,
2004 and 2003 were $1,168,000 and $4,736,000, respectively. Foreign currency
exchange gains and losses result from the re-valuation into U.S. dollars of
insurance related assets and liabilities as well as invested assets denominated
in foreign currencies. The principal foreign currencies re-valued into U.S.
dollars are the British pound and Euros. The decrease in net foreign currency
exchange losses in 2004 as compared with 2003 is due to less fluctuation of the
foreign currency exchange rates in 2004 as compared with 2003 as well as efforts
to better manage exposures to foreign currency exchange rate fluctuations by
holding invested assets denominated in the foreign currencies in which the
related net insurance assets and liabilities are denominated.

      Losses and LAE incurred and the resulting loss ratios for the three months
ended June 30, 2004 and 2003 were as follows ($ in thousands):



                         Three Months Ended June 30,
                         ---------------------------     Increase
                            2004              2003      (decrease)
                         ----------         -------     -----------
                                               
Losses and LAE           $  189,466         156,801     $    32,665
Losses and LAE ratio           60.9%           56.1%     4.8 points


      The increase in losses and LAE in 2004 as compared with 2003 is consistent
with the growth in business in the Casualty segment in 2004 and favorable
development in the Finite Risk segment in 2003, partially offset by the absence
of catastrophe losses in the Property and Marine segment in 2004. The increase
in the loss and LAE ratio in 2004 as compared with 2003 is due primarily to
favorable development during the three months ended June 30, 2003 related to the
2002 underwriting year, principally in the Finite Risk segment.

      Acquisition expenses and resulting acquisition expense ratios for the
three months ended June 30, 2004 and 2003 were as follows ($ in thousands):



                             Three Months Ended June 30,
                             ---------------------------     Increase
                                2004             2003       (decrease)
                              ---------         ------     -------------
                                                  
Acquisition expenses          $  62,694         60,376     $       2,318
Acquisition expense ratio          20.2%          21.6%     (1.4) points


      The increase in acquisition expenses is due primarily to the increase in
net premiums earned in 2004 as compared with 2003. The decrease in the
acquisition expense ratio is primarily related to lower commissions in the
Finite Risk segment, which may fluctuate depending upon profit commissions.
Profit commissions have an inverse relationship to the level of losses. The
acquisition expense ratio is also impacted by the mix of business and terms and
conditions on various contracts.

                                     - 15 -


      Operating expenses for the three months ended June 30, 2004 and 2003 were
$19,262,000 and $32,995,000, 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 for the three months
ended June 30, 2003 include a charge of $9.4 million for the payment to and
share option expense of the Company's former chief executive as well as various
start-up costs that are not recurring in 2004.

      Interest expense for the three months ended June 30, 2004 and 2003 was
$2,324,000 and $2,238,000, respectively, and relates to the Company's Equity
Security Units, which are classified as debt obligations on the Company's
balance sheet.

      Income taxes and the effective income tax rate for the three months ended
June 30, 2004 and 2003 were as follows ($ in thousands):



                            Three Months Ended June 30,
                            ---------------------------      Increase
                                2004           2003         (decrease)
                              --------        ------      -------------
                                                 
Income taxes                  $  4,857        12,324      $       (7,467)
Effective income tax rate          8.9%         31.7%      (22.8) points


      The decrease in the effective income tax rate in 2004 as compared with
2003 is the result of Platinum Bermuda providing an increasing proportion of
income before income taxes. During the three months ended June 30, 2004,
management revised its estimate of the annual effective tax rate for 2004 to
15%, resulting in an effective tax rate of 8.9% for the three months ended June
30, 2004. Additionally, the effective tax rate for the three months ended June
30, 2003 reflects expenses related to the payment to and share option expense of
the Company's former chief executive that were incurred by Platinum Holdings
without tax benefit thereby increasing the 2003 effective tax rate.

      Six Months Ended June 30, 2004 as Compared with the Six Months Ended June
30, 2003

      Net income for the six months ended June 30, 2004 and 2003 was as follows
($ in thousands):



                  Six Months Ended June 30,
                  -------------------------     Increase
                     2004             2003     (decrease)
                  ----------         ------    ----------
                                      
Net income        $  104,613         57,191    $   47,422


      The 83% increase in net income in 2004 as compared with 2003 is
principally due to the following: the increase in underwriting income of $25
million, the increase in investment income of $9.2 million, a charge for $9.4
million in 2003 for the payment to and share option expense of the Company's
former chief executive, a decline in foreign currency exchange losses of $4.5
million and a reduction in the effective income tax rate in 2004 as Platinum
Bermuda provides an increasing proportion of income before income taxes.

      Net premiums written and net premiums earned for the six months ended June
30, 2004 and 2003 were as follows ($ in thousands):



                           Six Months Ended June 30,

      The increase in net premiums written in 2004 as compared with 2003 is due
to increases in the Property and Marine and Casualty segments, partially offset
by a decrease in the Finite Risk segment. The increase in net premium 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.

      Net investment income for the six months ended June 30, 2004 and 2003 was
$36,861,000 and $27,634,000, respectively. Net investment income increased
during 2004 primarily due to increased invested assets attributable to positive
cash flow from operations, excluding trading securities activities, of
$394,964,000 during 2004. Net investment income for the six months ended June
30, 2003 included $1,357,000 of interest received from St. Paul on balances due
relating to the Quota Share Retrocession Agreements. Net realized gains (losses)
on investments of ($827,000) and $1,263,000 for the six months ended June 30,
2004 and 2003, respectively, were the result of investment sale activity to
manage the credit quality and duration of the investment portfolio and to
increase investments in municipal bonds.

      Other income for the six months ended June 30, 2004 and 2003 was
$1,116,000 and $3,900,000, respectively. Other income for the six months ended
June 30, 2004 includes $409,000 of net unrealized losses relating to changes in
fair value of fixed maturities classified as trading, $259,000 of earnings on
reinsurance contracts accounted for as deposits and a gain of $1,000,000 on the
sale of assets. There were no fixed maturities classified as trading or
unrealized gains or losses included in other income for the six months ended
June 30, 2003. Other income for the six months ended June 30, 2003 represents
earnings on reinsurance contracts accounted for as deposits. Earnings on
reinsurance contracts accounted for as deposits decreased in 2004 as compared
with 2003 due to lower margin reinsurance contracts accounted for as deposits.

      Net foreign currency exchange losses for the six months ended June 30,
2004 and 2003 were $302,000 and $4,812,000, respectively. Gains and losses
result from the re-valuation into U.S. dollars of insurance related assets and
liabilities as well as invested assets denominated in foreign currencies. The
decrease in net foreign currency exchange losses is due to efforts to better
manage exposures to foreign currency exchange rate fluctuations by holding
invested assets denominated in the foreign currencies in which the related net
insurance assets and liabilities are denominated.

      Losses and LAE incurred and the resulting loss ratios for the six months
ended June 30, 2004 and 2003 were as follows ($ in thousands):



                          Six Months Ended June 30,

Losses and LAE ratio           55.6%           57.1%     (1.5) points


      The increase in losses and LAE in 2004 as compared with 2003 is consistent
with the growth in business in the Casualty segment offset by the absence of
catastrophe losses in the Property and Marine segment in 2004. The decrease in
the loss ratio in 2004 as compared with 2003 is due primarily to the absence of
catastrophe losses in 2004.

Acquisition expense ratio            24.0%          21.7%     2.3 points


      The increase in acquisition expenses in 2004 as compared with 2003 is
consistent with the growth in business in the Property and Marine and Casualty
segments as well as an increase in profit commissions in the Finite Risk
segment. The increase in the acquisition expense ratio in 2004 as compared with
2003 is primarily due to an increase in profit commissions in the Finite Risk
segment. The increased profit commissions in Finite Risk contracts are the
direct result of favorable loss development experienced in 2004.

      Operating expenses for the six months ended June 30, 2004 and 2003 were
$38,036,000 and $53,164,000, 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 2003 include a
charge for $9.4 million for the payment to and share option expense of the

recurring in 2004.

$4,630,000 and $4,706,000, respectively, and relates to the Company's Equity
Security Units, which are classified as debt obligations on the Company's
balance sheet.

Effective income tax rate          15.0%          28.4%     (13.4) points


      The decrease in the effective income tax rate in 2004 as compared with
2003 is the result of Platinum Bermuda providing an increasing proportion of
income before income taxes Additionally, the effective tax rate in 2003 reflects
expenses related to the payment to and share option expense of the Company's
former chief executive that were incurred by Platinum Holdings without tax
benefit thereby increasing the 2003 effective tax rate.

SEGMENT INFORMATION

      The Company conducts its worldwide reinsurance business through three
operating segments: Property and Marine, Casualty and Finite Risk. In managing
the Company's operating segments, management uses measures such as underwriting
income and underwriting ratios to evaluate segment performance. Management does
not allocate by segment its assets or certain income and expenses such as
investment income, interest expense and certain corporate expenses. Segment
underwriting income is reconciled to income before income taxes. The measures
used by management in evaluating the Company's operating segments should not be
used as a substitute for measures determined under U.S. GAAP. The following
table summarizes underwriting activity and ratios for the three operating
segments for the three and six months ended June 30, 2004 and 2003 ($ in
thousands):

      PROPERTY AND MARINE

      The Property and Marine operating segment includes principally property
and marine reinsurance coverages that are written in the United States and
international markets. This business includes property per-risk excess-of-loss
treaties, property proportional treaties and catastrophe excess-of-loss
reinsurance treaties. This operating segment generated 30.8% and 27.1% of the
Company's net premiums written for

                                     - 20 -


the three months ended June 30, 2004 and 2003, respectively, and 33.7% and 30.2%
of the Company's net premiums written for the six months ended June 30, 2004 and
2003, respectively.

      Three Months Ended June 30, 2004 as Compared with the Three Months Ended
June 30, 2003

      Net premiums written and net premiums earned for the three months ended
June 30, 2004 and 2003 were as follows ($ in thousands):

Net premiums earned      $ 99,928            94,006      $ 5,922


      Net premiums written increased as a result of the growth in contracts
bound in both 2003 and 2004, which together generate net premiums written in
2004. The increase in net premiums written is also the result of a more
efficient use of catastrophe capacity through enhanced modeling capabilities, an
increase of property pro-rata business and a transfer of catastrophe capacity
from the Finite Risk segment to the Property and Marine segment.

      The increase in net premium 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.

      Losses and LAE incurred and the resulting loss ratios for the three months
ended June 30, 2004 and 2003 were as follows ($ in thousands):



                        Three Months Ended June 30,

Losses and LAE ratio          41.0%          55.8%     (14.8) points


      The decline in the loss ratio in 2004 as compared with 2003 is primarily
due to the difference in catastrophe experience in 2004 as compared with 2003.
There were no significant catastrophe losses in 2004, while catastrophe losses
in 2003 include losses arising from storms and flooding in the southeast United
States in April 2003 and tornadoes in the midwest United States in May 2003.
Additionally, losses and LAE incurred in 2004 include approximately $9,100,000
of favorable development of prior years' unpaid losses and LAE as compared with
approximately $4,600,000 of favorable development in 2003. During 2004 and 2003,
actual reported losses were significantly less than expected for these
short-tailed property lines resulting in reductions in estimated ultimate
losses.

      Acquisition expenses and resulting acquisition expense ratios for the
three months ended June 30, 2004 and 2003 were as follows ($ in thousands):

Acquisition expense ratio          14.9%          14.0%     0.9 points


      The increase in acquisition expenses in 2004 as compared with 2003 is
consistent with the growth in business in the Property and Marine segment and
the increase in the acquisition expense ratio. The increase in the acquisition
expense ratio in 2004 as compared with 2003 is attributable to lower loss

                                     - 21 -


ratios, which result in increased profit commissions in 2004 as compared with
2003, as well as mix of business changes.

      Other underwriting expenses for the three months ended June 30, 2004 and
2003 were $7,174,000 and $10,372,000, respectively, and represent costs such as
salaries, rent and like items. The decrease in other underwriting expenses is
due to cost reductions in the Property and Marine segment as well as various
start-up costs incurred in 2003 that are not recurring in 2004. Other
underwriting expenses for the three months ended June 30, 2004 and 2003 include
fees of $825,000 and $1,322,000, respectively, relating to an agreement with
RenaissanceRe that provides for a periodic review of aggregate property
catastrophe exposures by RenaissanceRe.

consistent with the growth in business in the Property and Marine segment and
the increase in the acquisition expense ratio. The increase in the acquisition
expense ratio is due to higher profit commissions in 2004 related to contracts
with favorable loss experience.

      Other underwriting expenses for the six months ended June 30, 2004 and
2003 were $15,324,000 and $20,831,000, respectively. The decrease in other
underwriting expenses is due to cost reductions in the Property and Marine
segment as well as various start-up costs incurred in 2003 that are not
recurring in 2004. Other underwriting expenses for the six months ended June 30,
2004 and 2003 include fees of $3,648,000 and $3,728,000, respectively, relating
to an agreement with RenaissanceRe that provides for a periodic review of
aggregate property catastrophe exposures.

      CASUALTY

      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. This segment also includes
accident and health reinsurance treaties, which are predominantly reinsurance of
health insurance products. This operating segment generated 34.1% and 43.1% of
the Company's net premiums written for the three months ended June 30, 2004 and
2003, respectively. This operating segment generated 41.5% and 36.8% of the
Company's net premiums written for the six months ended June 30, 2004 and 2003,
respectively.

      Three Months Ended June 30, 2004 as Compared with the Three Months Ended
June 30, 2003

      Net premiums written and net premiums earned for the three months ended
June 30, 2004 and 2003 were as follows ($ in thousands):



                      Three Months Ended June 30,

                           2004         2003       (decrease)
                         --------     -------      ----------
                                          
Net premiums written     $112,761     132,320       $(19,559)
Net premiums earned      $132,230     105,951       $ 26,279


      During the three months ended June 30, 2004, based on audits and
information received from ceding companies, the Company revised its estimates of
Casualty premiums and, consequently, the Company reduced its net premiums
written previously estimated and accrued. The effect of this change in estimate
was a reduction in net premiums written of approximately $27,000,000 and a
reduction in net premiums earned of approximately $15,800,000. Additionally,
during the three months ended March 31, 2004, approximately $17,000,000 of net
written premium related to a quota share contract was included in the Casualty
segment based on the expected terms and conditions of the contract. Based on the
final terms and conditions, the contract was reclassified as a Finite Risk
contract. Consequently, during the three months ended June 30, 2004 this
reclassification resulted in a reduction of approximately $17,000,000 of
Casualty net premiums written and an equivalent increase in Finite Risk net
premiums written. The net effect of these items on underwriting income, after
related reductions in losses, LAE and acquisitions expenses, was not material.
The increase in net premium 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.

      Losses and LAE incurred and the resulting loss ratios for the three months
ended June 30, 2004 and 2003 were as follows ($ in thousands):



                        Three Months Ended June 30,
                        ---------------------------     Increase
                            2004            2003       (decrease)

Losses and LAE ratio          70.6%          70.3%     0.3 points


      The increase in losses and LAE in 2004 as compared with 2003 is consistent
with the growth in business. The resulting loss ratios are reflective of
management's estimates of losses incurred for the Casualty segment.

      Acquisition expenses and resulting acquisition expense ratios for the
three months ended June 30, 2004 and 2003 were as follows ($ in thousands):



                             Three Months Ended June 30,

Acquisition expense ratio          24.2%          25.0%     (0.8) points


      The increase in acquisition expenses is due primarily to the increase in
net premiums earned in 2004 as compared with 2003. The resulting acquisition
expense ratios for the three months ended June 30, 2004 and 2003 were
comparable.

      Other underwriting expenses for the three months ended June 30, 2004 and
2003 were $5,305,000 and $4,542,000, respectively, and represent costs such as
salaries, rent and like items. The resulting other underwriting expense ratios
for the three months ended June 30, 2004 and 2003 were 4.0% and 4.3%,
respectively. The decrease in the ratio in 2004 as compared with 2003 is due
primarily to the increase in net premiums earned.

      Six Months Ended June 30, 2004 as Compared with the Six Months Ended June
30, 2003

      Net premiums written and net premiums earned for the six months ended June
30, 2004 and 2003 were as follows ($ in thousands):



                       Six months ended June 30,
                       -------------------------   Increase
                           2004         2003      (decrease)
                         --------     -------     ----------
                                         
Net premiums written     $336,726     246,014       $90,712
Net premiums earned      $268,452     183,677       $84,775


      The increase in premiums written is due to the growth in contracts bound
in both 2003 and 2004 that together generate net premiums written in 2004. In
response to market conditions, the Company previously increased its involvement
in the directors and officers and umbrella lines of business. The Company
expanded its participation with existing clients and formed new client
relationships. Additionally, in 2004 the Company expanded its participation in
surety and entered the trade credit line. Offsetting these increases were
revisions of estimates of Casualty premiums that resulted in reductions of net
premiums written of approximately $16,300,000 and a reduction in net premiums
earned of approximately $10,800,000. The net effect of the revisions of
estimates on underwriting income, after related reductions in losses, LAE and
acquisitions expenses, was not material. The increase in net premium 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.

Losses and LAE ratio           70.1%           69.9%     0.2 points


      The increase in losses and LAE in 2004 as compared with 2003 is consistent
with the growth in premiums earned. The resulting loss ratios in 2004 and 2003
were comparable. Improvements in the loss ratio in 2004, due to increased
profitability of the 2003 and 2004 underwriting years over the 2002 underwriting
year, were offset by adverse development in the U.K. Motor class of the Casualty
segment. In addition, losses and LAE in 2004 include losses arising from the
partial collapse of the new airport terminal in Paris, France.

      Acquisition expenses and resulting acquisition expense ratios for the six
months ended June 30, 2004 and 2003 were as follows ($ in thousands):

Acquisition expense ratio          24.9%          24.8%     0.1 points


      The increase in acquisition expenses is due primarily to the increase in
net premiums earned in 2004 as compared with 2003. The resulting acquisition
expense ratios in 2004 and 2003 are comparable.

      Other underwriting expenses for the six months ended June 30, 2004 and
2003 were $10,362,000 and $9,160,000, respectively. The resulting other
underwriting expense ratios for the six months ended June 30, 2004 and 2003 were
3.9% and 5.0%, respectively. The decrease in the ratio in 2004 as compared with
2003 is due primarily to the increase in net premiums earned.

      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 Company focuses on
providing such clients with customized solutions for their financial management
needs. This operating segment generated 35.1% and 29.8% of the Company's net
premiums written for the three months ended June 30, 2004 and 2003,
respectively. This operating segment generated 24.8% and 33.0% of the Company's
net premiums written for the six months ended June 30, 2004 and 2003,
respectively. For this segment, the Company believes it is especially important
to evaluate the overall combined ratio, rather than its component parts of loss
and expense ratios.

      Three Months Ended June 30, 2004 as Compared with the Three Months Ended
June 30, 2003

      Net premiums written and net premiums earned for the three months ended

                                     - 25 -


      The Finite Risk portfolio consists of a small number of contracts that can
be large in premium size and are written on an intermittent basis. Consequently,
net premiums written can be expected to vary significantly from period to
period. The increase in net premiums written for the three months ended June 30,
2004 is due primarily to several capped quota share contracts written in the
current year. During the three months ended March 31, 2004, approximately
$17,000,000 of net written premium related to a quota share contract was
included in the Casualty segment based on the expected terms and conditions of
the contract. Based on the final terms and conditions, the contract was
reclassified as a Finite Risk contract. Consequently, during the three months
ended June 30, 2004 this reclassification resulted in a reduction of
approximately $17,000,000 of Casualty net premiums written and an equivalent
increase in Finite Risk net premiums written. The net effect of the
reclassification on underwriting income, after related reductions in losses, LAE
and acquisitions expenses, was not material. Net premium earned is related to
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.

Losses, LAE and aquisition expense ratio          90.1%          63.6%      26.5 points


      The results of the Finite Risk segment in 2004 and 2003 were favorably
impacted by low levels of catastrophe losses. The results of the Finite Risk
segment in 2003 include the effects of a significant change to a reinsurance
program that resulted in an underwriting gain of $7,209,000. Favorable
experience on certain contracts resulted in $8,554,000 of underwriting gain in
2003 for the Finite Risk segment. The current Finite Risk book of business has a
greater proportion of lower risk and lower margin capped quota share contracts
and a lower proportion of higher margin catastrophe contracts than in 2003.
Consequently, the loss, LAE and acquisition expense ratio is higher in 2004 than
in 2003.

      Other underwriting expenses for the three months ended June 30, 2004 and
2003 were $2,567,000 and $4,732,000, respectively, and represent costs such as
salaries, rent and like items. The decrease in other underwriting expenses is
due to cost reductions in the Finite Risk segment as well as various start-up
costs incurred in 2003 that are not recurring in 2004.

      Six Months Ended June 30, 2004 as Compared with the Six Months Ended June

                                     - 26 -


      The decrease in net premiums written and net premiums earned is primarily
attributable to two significant finite quota share treaties that were written in
2003 and were not renewed in 2004, partially offset by other new business
production. Net premium earned is related to 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.

      Losses and LAE incurred, acquisition expenses and the resulting ratios for

      Losses and LAE in both 2004 and 2003 include favorable development. Losses
and LAE incurred in 2004 include a reduction of case loss reserve of $7,500,000
and a reduction of $9,700,000 related to the commutation of a reinsurance
contract. The increase in the acquisition expense ratio in 2004 as compared with
2003 is due primarily to a profit commission of $8,700,000 related to the
commutation. The results of the Finite Risk segment in 2003 include the effects
of a significant change to a reinsurance program that resulted in an
underwriting gain of $7,209,000 as well as favorable experience on certain
contracts that resulted in an underwriting gain of approximately $8,500,000.

      Other underwriting expenses for the six months ended June 30, 2004 and
2003 were $5,164,000 and $6,869,000, respectively. The decrease in other
underwriting expenses is due to cost reductions in the Finite Risk segment as
well as various start-up costs incurred in 2003 that are not recurring in 2004.

FINANCIAL CONDITION, LIQUIDITY AND CAPITAL RESOURCES

      FINANCIAL CONDITION

      Cash and cash equivalents were $172,227,000 as of June 30, 2004. Fixed
maturities were $1,975,276,000 as of June 30, 2004. The Company's fixed maturity
investment portfolio is comprised entirely of publicly traded investment grade
bonds. The investment portfolio, including cash and cash equivalents, had a
weighted average duration of 3.8 years as of June 30, 2004. Management monitors
the composition of the investment portfolio and cash flows from the portfolio to
maintain liquidity necessary to meet the Company's obligations. The Company
believes it has sufficient cash on hand to meet its short-term obligations and
to maintain the liquidity necessary for portfolio management.

      Certain assets and liabilities associated with underwriting have increased
significantly, some of which include significant estimates. Premiums receivable,
deferred acquisition costs, unpaid losses and LAE, unearned premiums and
commissions payable all include significant estimates. Premiums receivable of
$549,732,000 includes $461,898,000 of estimates of premiums that are accrued.
Unpaid losses and LAE, net of reinsurance recoverable, of $892,383,000 includes
$761,090,000 of estimates of losses that were incurred but not reported
("IBNR"). Commissions payable of $207,306,000 include $192,279,000 which are
estimated or contingent commissions payable.

      SOURCES OF LIQUIDITY

      The consolidated sources of funds of the Company consist primarily of
premiums written, losses recovered from retrocessionaires, investment income,
proceeds from sales and redemption of investments and actual cash and cash
equivalents held by the Company. Net cash flow provided by operations, excluding
trading securities activities, for the six months ended June 30, 2004 was
$394,964,000 and was used primarily to acquire additional investments.

      Platinum Holdings is a holding company that conducts no reinsurance
operations of its own. All of its reinsurance operations are conducted through
its wholly owned operating subsidiaries Platinum US, Platinum UK and Platinum
Bermuda. As a holding company, the cash flow of Platinum Holdings consists
primarily of dividends, interest and other permissible payments from its
subsidiaries. Platinum Holdings depends on such payments for general corporate
purposes and to meet its obligations, including the contract adjustment payments
related to the Equity Security Units and the payment of any dividends to its
shareholders.

      The Company has filed an unallocated universal shelf registration
statement with the Securities and Exchange Commission ("SEC"), which the SEC
declared effective on April 5, 2004. The securities registered under the shelf
registration statement for possible future sales include up to $750,000,000 of
common shares, preferred shares and various types of debt securities. The
registration statement also includes common shares held by St. Paul and
RenaissanceRe and common shares issuable upon exercise of options owned by St.
Paul and RenaissanceRe. On June 25, 2004, the Company announced St. Paul's
intent to sell 6,000,000 of the Company's common shares in an underwritten
public offering, which was effected pursuant to a prospectus supplement to the
shelf registration statement dated June 28, 2004 and completed on June 30, 2004.
The Company did not sell any common shares in the offering and did not receive
any proceeds from the sale of the common shares by St Paul. St. Paul continues
to hold an option to acquire 6,000,000 common shares of the Company. The
6,000,000 common shares sold by St. Paul amounted to $177,330,000 of the
$750,000,000 securities registered under the shelf registration statement.

      LIQUIDITY REQUIREMENTS

      The principal consolidated cash requirements of the Company are the
payment of losses and LAE, commissions, brokerages, operating expenses,
dividends to its shareholders, the servicing of debt (including interest
payments on the senior notes and contract adjustment payments on the purchase
contracts included in the Company's Equity Security Units), the acquisition of
and investment in businesses, capital expenditures, premiums retroceded and
excise taxes.

      Platinum UK and Platinum Bermuda are not licensed, approved or accredited
as reinsurers anywhere in the United States and therefore, under the terms of
most of their contracts with United States ceding companies, they are required
to provide collateral to these ceding companies for unpaid ceded liabilities in
a form acceptable to state insurance commissioners. Typically, this type of
collateral takes the form of a letter of credit issued by an acceptable bank,
the establishment of a trust, or a cash advance. Platinum UK and Platinum
Bermuda expect to obtain letters of credit through commercial banks and may be
required to provide the banks a security interest in certain of Platinum UK's
and Platinum Bermuda's investments. Platinum US and Platinum Bermuda have
reinsurance contracts that require them to provide collateral should certain
events occur such as a decline in the rating by A.M. Best below specified
ratings or a decline in statutory equity below specified amounts. Some
reinsurance contracts also have special termination provisions that require
collateral and/or permit early termination should certain events occur.

      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

                                     - 28 -


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 in 2004 without prior regulatory
approval is estimated to be $139,190,000.

      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 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 general economic conditions and conditions in the
insurance and reinsurance markets, 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
inflationary or recessionary periods can, however, impact the Company's
underwriting operations and investment portfolio. Management considers the
potential impact of economic trends in estimating its unpaid losses and LAE.

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
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. Certain of the
estimates and assumptions result from judgments that can be subjective and
complex, and consequently actual results may differ from these estimates. The
Company's most critical accounting policies involve written and unearned
premium, unpaid losses and LAE, reinsurance, investments, income taxes and
share-based compensation. The critical accounting policies presented herein are
discussed in more detail in the notes to the consolidated financial statements
included in the Company's Annual Report on Form 10-K for the year ended December
31, 2003.

      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, net of the cost of retrocession. Net
premiums written not yet recognized as revenue are recorded in 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 premium accruals. Along with estimating EBNR the Company records
the expenses associated with these premiums in the form of losses, LAE and
commissions. As actual premiums are reported by the ceding companies, management
evaluates the appropriateness of the premium estimates and any adjustment to
these estimates is recorded in the period in which it becomes known. Adjustments
to original premium estimates could be material and could significantly impact
earnings in the period they are recorded. Due to the time lag inherent in the
reporting of premiums by ceding companies, a significant portion of amounts
included as premiums written and receivable is estimated, net of commissions,
and is not currently due based on the terms of the underlying contracts.

                                     - 29 -


      Certain of our reinsurance contracts include provisions that adjust
premiums or acquisition expenses based upon the experience under the contracts.
Premiums written and earned, as well as related acquisition expenses under these
contracts, are recognized based upon the losses recorded under those contracts.

      Reinstatement premiums and additional premiums are recognized in
accordance with the provisions of assumed reinsurance contracts, based on losses
recorded 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 during the remainder of
the initial contract term and are earned over the remaining contract term.
Additional premiums are those premiums triggered by losses and not related to
reinstatement of limits and are earned immediately. An allowance for
uncollectable premiums is established for possible non-payment of such amounts
due, as deemed necessary.

      UNPAID LOSSES AND LAE

      The most significant judgment made by management in the preparation of
financial statements is the estimation of unpaid losses and LAE liabilities also
referred to as "loss reserves." These liabilities are balance sheet estimates of
future amounts required to pay losses and LAE for reinsured claims, which have
occurred at or before the balance sheet date. Every quarter, the Company's
actuaries prepare estimates of loss reserves based on established actuarial
techniques. Because the ultimate amount of unpaid losses and LAE is uncertain,
we believe that quantitative techniques to estimate these amounts are enhanced
by professional and managerial judgment. Company management reviews these
estimates and determines its best estimate of the liabilities to record in the
Company's financial statements.

      Loss reserves include estimates of the cost of claims that were reported
but not yet paid ("case reserves") and the cost of IBNR. Case reserves are
usually based upon claim reports received from ceding companies, and may be
increased or reduced by the Company's claims personnel. 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's estimated exposure to an industry loss. This estimation
process may include the use of catastrophe modeling software.

      Generally, initial actuarial estimates of IBNR not related to a specific
event are based on the loss ratio method applied to each underwriting year for
each class of business. Actual paid losses and case reserves ("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's pricing
process, and (ii) historical loss ratios of the Company and St. Paul adjusted
for rate changes and trends. These judgments will take into account management's
view of past, current and future: (i) market conditions, (ii) changes in the
business underwritten, (iii) changes in timing of the emergence of claims and
(iv) other factors that may influence expected ultimate losses.

      Over time, as a greater number of claims are reported, actuarial estimates
of IBNR are based on the Bornhuetter-Ferguson and the chain ladder techniques.
The Bornhuetter-Ferguson technique utilizes actual reported losses and expected
patterns of reported losses, taking the initial expected ultimate losses into
account to determine a new 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 a new
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

                                     - 30 -


credibility and a relatively stable pattern of reported losses. The pattern of
reported losses is determined utilizing actuarial analysis including judgment
and is based on historical patterns of the recording of paid losses and case
reserves to the Company, as well as industry patterns. Information that may
cause historical patterns to differ from future patterns is considered and
reflected in expected patterns as appropriate. For property and health 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 well 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 the reinsurance underwriting
segment of St. Paul ("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.

      Under U.S. GAAP, we are not permitted to establish liabilities until the
occurrence of an event that may give rise to a loss. When an event occurs of
sufficient magnitude we may establish a specific IBNR reserve. Generally, this
involves a catastrophe occurrence, which affects many ceding company clients.
Ultimate losses and LAE are based on management's judgment that reflects
estimates gathered from ceding company clients, 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 because, among other things,
they are based on predictions of future developments and estimates of future
trends in claim severity and frequency and other factors.

      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 uncertainty inherent in the reserving process
for primary insurers is even greater for the reinsurer. This is because of, but
not limited to, the time lag inherent in reporting information from the primary
insurer to the reinsurer and differing reserving practices among ceding
companies.

      Loss reserves are refined 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.

      REINSURANCE

      Written premiums, earned premiums, incurred 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 risk transfer involves 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
significant insurance risk are

                                     - 31 -


generally accounted for as reinsurance deposit liabilities with interest expense
charged to other income and credited to the liability.

      INVESTMENTS

      In accordance with our investment guidelines, our investments consist
largely of high-grade marketable fixed income securities. Fixed maturities for
which the Company may not have a 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 that the Company has 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. Securities classified as trading
securities are generally foreign currency denominated securities intended to
match foreign currency denominated liabilities 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. In addition, unrealized depreciation in the value of
individual securities considered by management to be other than temporary is
charged to income in the period it is determined. Investment income is recorded
when earned and includes the amortization of premiums and discounts on
investments.

      INCOME TAXES

      Platinum Holdings and Platinum Bermuda are domiciled in Bermuda, which has
no corporate income tax. The Company also has subsidiaries in the United States,
United Kingdom and Ireland that are subject to the tax laws thereof.

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

      SHARE BASED COMPENSATION

      During 2003, the Company adopted 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 that the fair value of share options granted under the
Company's share option plan subsequent to the adoption 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 transitioning guidance for a voluntary adoption of
FAS 123 as well as amends the disclosure requirements of SFAS 123. Prior to the
adoption of SFAS 123, the Company elected to use the intrinsic value method of
accounting for its 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 option
granted in 2002. Under APB 25, if the exercise price of the Company's employee
share options is equal to or greater than the fair market value of the
underlying shares on the date of the grant, no compensation expense is recorded.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

MARKET AND CREDIT RISK

      The Company's principal invested assets are fixed maturities, which are
subject to the risk of potential losses from adverse changes in market rates and
prices and credit risk resulting from adverse changes in the borrower's ability
to meet its debt service obligations. The Company's strategy to limit this risk
is to place its investments in high quality credit issues and to limit the
amount of credit exposure with respect to any one issuer or industry. The
Company also selects investments with characteristics such as duration, yield,
currency and liquidity to reflect the underlying characteristics of related
estimated claim liabilities. The Company attempts to minimize the credit risk by
actively monitoring the portfolio and requiring a minimum average credit rating
of A2 as defined by Moody's Investor Service. As of June 30, 2004, the portfolio
has a dollar weighted average rating of Aa3.

      The Company has other receivable amounts subject to credit risk. The most
significant of these are reinsurance premiums receivable from ceding companies
and losses recoverable from retrocessionaires. To mitigate credit risk related
to losses recoverable from retrocessionaires, we establish business and
financial standards for retrocessionaire approval, incorporate ratings by major
rating agencies, consider current market information, and obtain letters of
credit or other forms of security where deemed necessary. To mitigate credit
risk related to premium receivables, we have established standards for ceding
companies and, in most cases, have a contractual right of offset thereby
allowing the Company to settle claims net of any premium receivable.

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 income portfolio
and can cause changes in the actual timing of when we expect to receive certain
principal payments. Rising interest rates result in a decline in the market
value of our fixed income 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 our fixed income
portfolio and can expose our portfolio, in particular our mortgage backed
securities, to prepayment risk. The aggregate hypothetical impact on our fixed
income portfolio, generated from an immediate parallel shift in the treasury
yield curve, as of June 30, 2004 is approximately as follows ($ in thousands):



                                                              Interest Rate Shift in Basis Points

FOREIGN CURRENCY RISK

      The Company writes business on a worldwide basis. Consequently, the
Company's principal exposure to foreign currency risk is its obligation to
settle claims 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.

SOURCES OF FAIR VALUE

      The following table presents the carrying amounts and estimated fair
values of the Company's financial instruments as of June 30, 2004 ($ in
thousands):



                            Carrying

Financial liabilities:
  Debt obligations         $  137,500     $  166,265


      The fair value of fixed maturities is based on quoted market prices at the
reporting date for those or similar investments. The fair values of debt
obligations are based on quoted market prices. Other invested asset represents a
strategic investment in a non-public reinsurance company and is carried at
estimated fair value.

CURRENT OUTLOOK

      We believe that our markets continue to provide strong opportunities.
Currently, we believe that premium rates in certain casualty reinsurance markets
have strengthened to attractive levels. We believe that premiums in our Casualty
segment will grow. Because there are areas of the casualty market where, in our
view, pricing is inadequate, we are being selective and write business only when
we believe it will be profitable.

      We believe that the additional capacity provided to the reinsurance market
subsequent to September 11, 2001, as well as light catastrophe losses in 2002,
2003 and 2004 year-to-date have begun to cause pricing in the property
catastrophe market to decrease. Decreases to date have been modest and we
believe that rates remain at attractive levels. Significant time and effort has
been invested in developing sophisticated catastrophe modeling tools that assist
us in identifying profitable business opportunities. We believe we can maintain
an acceptable risk/reward relationship in our portfolio and grow the Property
and Marine segment while managing our catastrophe exposure risk within
acceptable levels.

      We believe that the Finite Risk segment has performed exceptionally well
in 2003 and 2004 year-to-date. Profitability was favorably influenced by a
relatively low level of current losses and contractual terms and conditions that
provided for greater profit opportunity as a result of significant losses
incurred in prior periods by St. Paul Re. We believe opportunities to write
finite contracts will remain though current market conditions are unlikely to
produce the profitability experienced in 2003.

      We routinely review various opportunities for investments or transactions
that would provide an attractive return on equity or an opportunity to write new
classes of business or access additional markets.

ITEM 4. CONTROLS AND PROCEDURES

      The Company carried out an evaluation, under the supervision and with the
participation of our management, including the Chief Executive Officer and Chief
Financial Officer, of the effectiveness of the design and operation of our
disclosure controls and procedures as of the end of the period covered by this
report pursuant to Rule 13a-15 promulgated under the Securities Exchange Act of
1934. Based on

                                     - 34 -


that evaluation, our management, including the Chief Executive Officer and Chief
Financial Officer, concluded that our disclosure controls and procedures are
effective in timely alerting them to material information required to be
included in our periodic reports to be filed with the Securities and Exchange
Commission. In addition, there have been no significant changes in our internal
controls over financial reporting that materially adversely affected or are
reasonably likely to materially adversely affect the Company's internal controls
over financial reporting subsequent to the date of their evaluation, including
any corrective actions with regard to significant deficiencies or material
weaknesses. It should be noted that the design of any system of controls is
based in part upon certain assumptions about the likelihood of future events,
and there can be no assurance that any design will succeed in achieving its
stated goals under all potential future conditions, regardless of how remote.

FORWARD-LOOKING STATEMENTS

      This Form 10-Q contains forward-looking statements within the meaning of
Section 27A of the Securities Act of 1933 and Section 21E of the Securities
Exchange Act of 1934. Forward-looking statements are necessarily based on
estimates and assumptions that are inherently subject to significant business,
economic and competitive uncertainties and contingencies, many of which are
subject to change. These uncertainties and contingencies can affect actual
results and could cause actual results to differ materially from those expressed
in any forward-looking statements made by, or on behalf of, us.

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

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

      (1)   our ability to successfully execute our business strategy;

      (2)   conducting operations in a competitive environment;

      (3)   our ability to maintain our A.M. Best Company rating;

      (4)   significant weather-related or other natural or man-made disasters
            over which the Company has no control;

      (5)   the effectiveness of our loss limitation methods;

      (6)   the adequacy of the Company's liability for unpaid losses and loss
            adjustment expenses;

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

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

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

      (10)  the cyclicality of the property and casualty reinsurance business;

                                     - 35 -


      (11)  market volatility and interest rate and currency exchange rate
            fluctuation;

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

      (13)  changes in the Company's plans, strategies, objectives, expectations
            or intentions, which may happen at any time at the Company's
            discretion.

      As a consequence, current plans, anticipated actions and future financial
condition and results may differ from those expressed in any forward-looking
statements made by or on behalf of the Company. The foregoing factors should not
be construed as exhaustive. Additionally, forward-looking statements speak only
as of the date they are made, and we undertake no obligation to release publicly
the results of any future revisions or updates we may make to forward-looking
statements to reflect new information or circumstances after the date hereof or
to reflect the occurrence of future events.

                           PART II - OTHER INFORMATION
