Converium Today Reports on its Financial Results for the Second Quarter 2004


ZUG, Switzerland, July 27, 2004 (PRIMEZONE) -- Converium has resolutely addressed its pre-IPO legacy issues by strengthening reserves for prior years' US casualty business to the amount of US$385 million. This reserve action triggers impairments of deferred tax assets (US$270 million net) and goodwill (US$94 million).

As announced on July 20, 2004, Converium experienced continuing higher than modeled US casualty loss emergence, primarily related to the underwriting years 1997 to 2001. Against this backdrop, Converium initiated a detailed internal review of its US casualty book in the second quarter of 2004. This review is based on an integrated approach combining underwriting, claims management, actuarial pricing, and reserving perspectives. The results to date have prompted Converium to bolster reserves for US general liability and specialty liability lines of business - in particular umbrella, professional liability, and excess & surplus lines(2) - by US$384.7 million. As part of this review and to assist with its assessment, Converium has commissioned a leading firm of consulting actuaries to conduct an external actuarial study of the Company's reserves held in respect of the Zurich and New York businesses. The study will be completed before the end of August.

These reserve actions triggered net impairments of US$269.8 million of deferred tax assets and US$94.0 million of goodwill; both impairments affect the balance sheet of Converium Reinsurance (North America) Inc.

The reserve strengthening, the impairments of intangible balance sheet positions, and additional changes in Converium's equity resulted in a reduction of US$409.4 million of Converium's total tangible equity since year-end 2003.

Converium is fully committed to maintaining a strong capitalization that enables us to continue to execute our post-IPO strategy. In order to achieve this objective, Converium is currently exploring all options. The spectrum includes measures to de-leverage and de-risk Converium's balance sheet resulting in reduced capital requirements and transactions that would strengthen the capital base.

More specifically, Converium is taking the following actions in order to reduce capital consumption:

-- Converium will decrease investments in equity securities and re-classify certain OECD government bonds from available-for-sale to held-to-maturity. These measures are expected to reduce capital requirements for investment risks by up to US$ 125 million.

-- Converium is currently working on retrospective and prospective reinsurance solutions to mitigate premium and reserving risks. These solutions are aimed at reducing capital requirements by US$ 50 million to US$ 100 million.

Additionally, Converium is considering methods to bolster its capital base, including the raising of additional capital. Based on the information currently available Converium expects to increase its capital base by US$ 250 million to US$ 400 million in order to maintain a strong capitalization. Converium will specify the full set of capital management measures once the external actuarial reserve study is completed.

At the operating level, Converium will take the following immediate steps to protect and enhance the underlying profitability of its operations:

-- Converium intends to establish a run-off unit focusing on business written in underwriting years 2001 and prior and will pursue an active commutation strategy.

-- In the United States, Converium will substantially reduce its exposure to lines of business which are capital-intensive due to their high volatility. This would include so-called national account writers of lead umbrella and excess & surplus lines, as well as heavy commercial auto written on an excess basis. In addition, Converium anticipates that it will significantly reduce its writings of directors' & officers' liability due to its concern of a weakening in market and policy conditions.

Converium's resolute steps to deal with its legacy issues should not detract from the fact that recent underwriting years continue to show a sound profitability. Excluding reserve developments, Converium reported a non-life combined ratio of 97.2% for the second quarter of2004, an improvement of 2.6 percentage points compared to the same period of the prior year, and 94.2% for the first half of 2004, an improvement of 4.1 percentage points compared to the same period of2003.

The Chairman of the Board of Directors, Peter Colombo, said: "The Board of Directors is in regular communication with management to discuss the proposed actions to address the current situation. It is the Board's view that the course of action proposed by the CEO and the Global Executive Committee is in the best interest of our shareholders."

Converium is determined to put an end to the US casualtyreserving saga

Sound performance of recent underwriting years continues

Investment results in line with benchmarks

Converium has experienced significant adverse development in its US casualty reinsurance lines for the last several years. Since 2001,Converium recorded a total of US$ 668.5 million of additional provisions on certain non-life business (2001: US$ 123.6 million;2002: US$ 148.5 million; 2003: US$ -31.3 million; and first half of2004: US$ 427.7 million). In 2003, the positive development of US$31.3 million consisted of positive development on property lines (US$113.5 million) and aviation and space (US$ 102.2 million), offset by an adverse development on workers' compensation and professional liability and other specialty liability lines (US$ 120.3 million) and the motor and general third party liability lines (US$ 64.1million). The reserve releases in 2003 were primarily from the 2002underwriting year, while the US business written in 1997 to 2001mainly saw continued strengthening.

On April 29, 2004, Converium announced that first quarter reported losses from prior years' US casualty business had exceeded expected loss emergence. In that release, Converium also stated the expectation that the volatility of longer-tail risks is likely to persist for some time. In the first quarter of 2004, the continuing reserve volatility of old underwriting years resulted in net strengthening of prior years' loss reserves of US$ 43.0 million, consisting of US$ 10.1 million (primarily from the Western European motor book) in the Standard Property & Casualty Reinsurance segment and US$ 32.9 million in the Specialty Lines segment (particularly on US business in the professional liability and other special liability lines). This adverse loss reporting trend has continued and accelerated in the second quarter of 2004. In response to the loss development observed in the first and second quarters of 2004,Converium has initiated additional reviews of its US casualty business from an integrated underwriting, claims and actuarial perspective in order to examine the adequacy of prior years' provisions. The Chief Executive Officer and Chief Technical Officer have conducted underwriting reviews on treaty accounts and lines of business with material loss experience, supported by claims audits and actuarial reserve reviews which Converium conducts in its ordinary course of business. When deriving its estimates of ultimate losses and its selection of loss development patterns as of June 30,2004, Converium has reflected the accelerated claims development in the more recent periods.

In the second quarter of 2004, based upon Converium's ongoing analysis to date, Converium recorded strengthening of prior years' loss reserves of US$ 384.7 million, consisting of US$ 96.0 million in the Standard Property & Casualty Reinsurance segment and US$ 288.7million in the Specialty Lines segment. In the Standard Property &Casualty Reinsurance segment, the reserve strengthening primarily occurred with respect to general third party liability lines (US$99.3 million) in the United States. In the Specialty Lines segment, the reserve strengthening arose primarily from the professional liability and other special liability lines, in particular umbrella, professional liability, and excess & surplus lines of business (US$265.2 million) in the United States, related to accident years 1997through 2001.

Converium commissioned a leading firm of consulting actuaries to conduct a reserve review that will be completed before the end of August. Any adjustment to Converium's estimate of its loss reserve position and potential loss exposure that is indicated by this work will be recorded in the third quarter of 2004.

Based upon the information currently available, Converium does not expect further material strengthening of its loss reserve position.

Converium's investment results were in line with the respective benchmarks. In the second quarter of 2004, rising interest rates lento a change in net unrealized gains on investments (pre-tax) of minus US$ 139.2 million. The fact that approximately 30% of Converium's fixed-maturities portfolios (including the Funds Withheld Asset) are not interest-rate-sensitive should mitigate the adverse impact on total equity of a possible future rise in interest rates.

Converium's consolidated income tax expense for the three and six months ended June 30, 2004 reflected an additional expense of US$269.8 million net, related to the establishment of a full valuation allowance against the net deferred income tax balances carried at Converium Reinsurance (North America) Inc., the legal entity where the majority of the reserve strengthening occurred. As of June 30,2004, Converium had total net operating losses carried forwards of US$ 959.1 million available to offset future taxable income of certain branches and subsidiaries. The majority of these net operating losses carried forwards relate to Converium Reinsurance(North America) Inc. and will expire in the years 2020 through 2024.

Cash flows decreased by 22.7% to US$ 442.5 million, due to the slowing down of new business growth as a result of an active cycle management. This decrease also reflects increased claims payment activity.

Based on stable exchange rates, gross premiums written increased by3.8%, net premiums written increased by 2.6% and net premiums earned increased by 6.3%.

Business Development

The following are comments on the development of Converium's three main business segments and the Corporate Center. Reference is made to the tables attached to this press release.

Converium's distribution platform enables us to achieve a book of business that is geographically diversified, broadly spread by line of business, and balanced by speed of settlement. Converium continues to apply strict underwriting discipline and cycle management in order to achieve adequate returns on risk-based capital.

The decrease of the property line was primarily driven by the softening of property rates and a consequent non-renewal of several large contracts in North America and the reduced premium writings from Asia and Latin America. The strong growth in the motor line reflects Converium's strong market position in Western Europe. The premium development in the general third party liability line is the result of growth in Western Europe that was offset by reduced writings in the United States during the second quarter.

Overall, the results of Converium's catastrophe business were well within the model-based expectations.

During the second quarter of 2004, US$ 96.0 million of reserve strengthening were recorded. This reserve strengthening was driven by the general third party liability line in the United States (US$99.3 million).

The Standard Property & Casualty Reinsurance segment's non-life combined ratio7 was 122.2% for the second quarter of 2004 (compared to 93.1% for the second quarter of 2003) including the reserve strengthening.

Based on stable exchange rates, gross premiums written increased by1.0%, net premiums written decreased by 1.6%, and net premiums earned increased by 2.7%.

Specialty Lines represented 57% of total net premiums written in the second quarter of 2004. For the second quarter of 2004 Converium's Specialty Lines segment reported a segment loss of US$ 224.3 million compared to a segment income of US$ 21.0 million for the same period of the previous year.

In the second quarter of 2004, gross premiums written increased by25.6% to US$ 566.7 million, net premiums written increased by 31.5%to US$ 537.3 million and net premiums earned increased by 13.6% to US$ 471.6 million.

The Specialty Lines' book of business is driven by Converium's particular position in those segments of the global reinsurance market place where entry barriers are defined by specific underwriting skills and market expertise. Converium is committed to applying strict underwriting discipline and cycle management in order to achieve adequate returns on risk-based capital allocated to the Specialty Lines segment.

The strong growth in the professional liability and other special liability lines resulted from reduced writings in the United States that were offset by a strong growth of new business written in Western Europe. In the aviation and space line of business, the growth in premium mirrored the increase in Converium's share in the pools managed by Global Aerospace Underwriting Managers Limited and a switch in the structure of inuring protections for the pool from proportional to excess of loss reinsurance. The credit & surety line grew as a result of new business written and increased shares on existing business.

During the second quarter of 2004, US$ 288.7 million of reserve strengthening were recorded. The Specialty Lines segment's non-life combined ratio7 was 157.2% for the second quarter of 2004 (compared to 105.5% for the second quarter of 2003) including the reserve strengthening, and 96.0% excluding the reserve strengthening, reflecting the strong underlying profitability of this segment's most recent underwriting years.

Based on stable exchange rates, gross premiums written increased by4.4%, net premiums written increased by 5.1% and net premiums earned increased by 7.4%.

Life & Health Reinsurance represented 10% of total net premiums written in the second quarter of 2004. For the second quarter 2004Converium's Life & Health Reinsurance segment reported a segment income of US$ 1.0 million, a decrease of US$ 10.7 million (2Q2003:US$ 11.7 million) compared to the same period of 2003.

In the second quarter 2004, gross premiums written increased by 36.5%to US$ 108.0 million, net premiums written increased by 5.5% to US$94.6 million, and net premiums earned increased by 26.3% to US$ 121.5million.

  - growth (%)            +7.3%             +5.7%                    

The strong growth in the life & disability line was driven by the expansion of existing financing reinsurance transactions in Continental Europe and increased shares of current business.

The Life & Health Reinsurance segment's technical result8 for the second quarter of 2004 was US$ 3.6 million, a decrease of US$ 6.4million compared to the prior year. This decrease was primarily attributable to an increase in underwriting acquisition costs in 2004as compared to 2003 due to the revision of profit commission accruals for North American accident and health business. In addition, there were increases in commissions related to premium growth in financing reinsurance transactions in Continental Europe.

Based on stable exchange rates, gross premiums written increased by13.9%, net premiums written increased by 9.9%, and net premiums earned increased by 16.6%.

The Corporate Center carries certain administration expenses such as the costs of the Board of Directors, the Global Executive Committee, and other global functions. In the second quarter of 2004 other operating and administration expenses were US$ 7.3 million(unchanged).

The company has made it a policy not to provide any quarterly or annual earnings guidance and it will not update any past outlook for full year earnings. It will however provide investors with perspectives on its value drivers, its strategic initiatives and those factors critical to understanding its business and operating environment.
