Form 6-K SECURITIES AND EXCHANGE COMMISSION Washington, D.C. 20549 Report of Foreign Private Issuer Pursuant to Rule 13a-16 or 15d-16 of the Securities Exchange Act of 1934 For the month of July, 2005 CONVERIUM HOLDING AG ---------------------------------------------- (Translation of registrant's name into English) Baarerstrasse 8 CH-6300 Zug Switzerland --------------------------------------- (Address of principal executive offices) Indicate by check mark whether the registrant files or will file annual reports under cover Form 20-F or Form 40-F. Form 20-F X Form 40-F --- --- Indicate by check mark whether the registrant by furnishing the information contained in this Form is also thereby furnishing the information to the Commission pursuant to Rule 12g3-2(b) under the Securities Exchange Act of 1934. Yes No X --- --- If "Yes" is marked, indicate the file number assigned to the registrant in connection with Rule 12g3-2(b): 82- Not Applicable Converium Holding Ltd, Zug Zug, Switzerland - August 9, 2005 - Converium produces a positive result in the second quarter of 2005. o For the second quarter of 2005 Converium reports income before taxes of US$ 49.2 million, pre-tax operating income(1) of US$ 60.7 million and net income of US$ 70.8 million. All business segments contributed to the quarter's positive result. o The encouraging result reflects a solid technical underwriting performance, supported by the absence of any major catastrophic events, and a strong total investment result. Net income further increased as a result of an income tax benefit. o Prior year loss reserves have remained stable. For three consecutive quarters there were only minor loss reserve movements. o Converium remains confident about the economic profitability of its ongoing business. The non-life combined ratio, excluding an administration expense ratio of 8.8%, was 93.6%. This is a satisfactory result given the large share of proportional and medium- to long-tail business in Converium's portfolio. o Converium's results are only partially reflective of the cost reduction measures initiated in March 2005. Their effect continues to be offset by costs resulting from staff retention plans and expenses which Converium considers vital investments to facilitate a fast rebound. o In the second quarter Converium generated a total investment result of US$ 86.8 million, resulting in an average annualized total investment income yield (pre-tax) of 4.3% on average total invested assets of US$ 8,070.9 million. Terry Clarke, CEO, said: "I am very pleased that Converium has swung back to a positive result in the second quarter of 2005. We have seen a favorable development of prior year loss reserves for both the ongoing and the run-off operation. For the third consecutive quarter, prior year reserve movements have been minor. In addition, our ongoing operations, which continue to be affected by a temporarily inflated cost base, remain profitable." Mr. Clarke added: "I am confident that the second quarter marks a turning point on our way to full recovery. We now start to reap the benefits from the relentless efforts of our staff to put Converium back on track." (1) Pre-tax operating income (loss) is defined as income (loss) before taxes excluding net realized capital gains (losses), impairment of goodwill, amortization of intangible assets and restructuring costs.

For the first half of 2005 this translates into a loss before taxes of US$ 16.4 million, pre-tax operating income of US$ 12.9 million and net income of US$ 9.0 million. This compares with a loss before taxes of US$ 295.5 million, a pre-tax operating loss of US$ 221.7 million and a net loss of US$ 594.3 million for the same period of 2004. The decrease in gross premiums written, net premiums written, and net premiums earned in the second quarter of 2005 (by 64.8%, 65.1% and 39.3% compared to the same period in 2004) reflects the reduction in business volume caused by the placement of Converium Reinsurance (North America) Inc. (CRNA) into orderly run-off in 2004 and the impact of the ratings downgrades which prompted clients to cancel their business or reduce their shares with Converium. Despite the decrease in premiums, there was still some growth in the Agribusiness, Aviation and Accident & Health lines of business resulting from increased shares in existing business and new client relationships. In addition, due to the seasonality involved with the renewal of its business in different markets, Converium generally records the largest share of its premium volume in the first quarter of a given year and approximately half of its annual premium volume by the end of the second quarter of a given year. (2) Segment income (loss) is defined as net premiums earned plus total investment results minus losses, loss adjustment expenses and life benefits, underwriting acquisition costs and other operating and administration expenses. Satisfactory results of ongoing business segments The non-life combined ratio for Converium's ongoing operations was 102.4% (including an administration expense ratio of 8.8%) for the second quarter of 2005 compared to 108.7% in the same period of 2004. For the first half of 2005 and 2004 the non-life combined ratio for the ongoing operations was 108.9% (including an administration expense ratio of 7.2%) and 100.7%, respectively. This is a satisfactory result as almost two-thirds of Converium's ongoing portfolio consist of medium- and long-tail business and therefore generate substantial investment income over time. In addition, Converium's mix of business has shifted from non-proportional to proportional business which generally carries higher underwriting expenses. Converium is also pleased about the broad-based character of its profitable quarter. All business segments made a positive contribution to the bottom-line in the second quarter. The Standard Property & Casualty Reinsurance, Specialty Lines and Life & Health Reinsurance segments reported a segment income of US$ 32.5 million, US$ 41.3 million and US$ 0.3 million, respectively. The Run-Off segment recorded segment income of US$ 6.9 million for the second quarter supported by net positive development of prior years' loss reserves. As of June 30, 2005 Converium has not yet concluded and legally bound further material commutations with its cedents. The Company is vigorously executing its commutation strategy and reiterates its target to commute or otherwise settle CRNA's liabilities of approximately US$ 500 million in 2005. Favorable loss reserve developments In the second quarter of 2005 Converium recorded net positive development of prior years' loss reserves of US$ 6.7 million, including a net positive development of US$ 3.1 million in the Run-Off segment. This compares with net strengthening of prior years' loss reserves of US$ 387.7 million in the same period of 2004. For the first half of 2005 the Company recorded net strengthening of prior years' loss reserves of US$ 3.7 million as compared to net strengthening of US$ 430.7 million in the first half of 2004. Converium is pleased about the second quarter 2005 being the third consecutive quarter with only minor prior year loss reserve developments. Converium believes this outcome to reflect the adequacy of prior years' loss reserve actions. Strong total investment result In the second quarter of 2005 Converium generated total investment results of US$ 86.8 million or an average annualized total investment income yield (pre-tax) of 4.3%. Investments continued to perform strongly as compared to the same period of 2004, reflecting a moderate growth in average total invested assets, including cash and cash equivalents as well as an allocation shift from equity securities to fixed income securities in mid-2004. Converium's asset mix is now characterized by a higher allocation to relatively high-yielding fixed income securities. In addition, Converium benefited from higher investment income generated by business written on a funds withheld basis. In the second quarter of 2005, net realized capital losses amounted to US$ 1.0 million as compared to net realized capital gains of US$ 12.5 million in the same period of 2004 that were driven by the sale of certain equity investments to adjust Converium's asset allocation with the objective of reducing investment risk during 2004. Cost base affected by timing of cost management measures and vital investments to facilitate the Company's rebound In the second quarter of 2005, the administration expense ratio for the ongoing non-life business was 8.8% as compared to 4.6% in the same period of 2004. Other operating and administration expenses for the Company were US$ 50.2 million, a decrease of US$ 4.5 million compared to the same period of 2004 and a decrease of US$ 6.7 million compared to the first quarter of 2005. The economics of Converium's ongoing operations continue to be masked by the Company's relatively high administration expense base. At this point in time, the administration expenses are only partially reflective of the strict cost management measures initiated in March 2005. These measures are expected to show effect by the end of 2005. In addition, the expense base and accordingly the ongoing non-life combined ratio carry the cost of staff retention plans. Furthermore, Converium incurs certain expenses which it considers crucial investments in order to be able to rapidly capitalize on the restoration of its financial strength ratings which are expected for 2006, and to accelerate the recovery of its market position. Net income increased as a result of an income tax benefit Converium recorded an income tax benefit of US$ 21.6 million and US$ 25.4 million for the second quarter and the first half of 2005, respectively. Over the past year, Converium has established a full valuation allowance against existing tax losses carried forward in its primary locations, resulting in minimal current income tax expense relating to pre-tax income. Therefore tax benefits and expenses are primarily driven by the development of existing deferred tax assets and liabilities, which are established to reflect differences in the tax accounting rules of local jurisdictions and US GAAP accounting. In the second quarter of 2005, Converium's income tax benefit resulted from the reduction of deferred acquisition costs (DAC), caused by the decline in its overall non-life premium volume, as well as certain timing differences related to the recognition of investment gains and losses. Encouraging July 1 renewals For Converium's ongoing non-life operations approximately 7% of the in-force portfolio was up for renewal in July. The main renewal areas were Latin America and the Caribbean. The Company retained almost two-thirds of the renewable business. In ratings-sensitive lines of business (e.g. Aviation) and geographical markets (Australia), Converium recorded, as expected, a major decline in renewed business volume. In Latin America, however, about 75% of the renewable business was successfully retained. In the Middle East region Converium even increased premium volume. Overall, this outcome is in line with expectations. Converium therefore continues to believe that its US$ 2 billion gross premiums written target for the 2005 calendar year is achievable. Short-term outlook: Continued implementation of Converium's roadmap to recovery Converium will continue to focus on the systematic implementation of its roadmap to recovery: o Operate as a stand-alone entity: The outcome of the July renewals confirms the trend established by the January and April renewals. Converium's franchise continues to prove resilient and viable. o Right-size the organization: Converium is committed to strict cost management in view of the reduced top-line. The Company continues to target administration expenses for its ongoing operations at a ratio of 6.5% of net premiums written in 2006, which includes certain investments vital for a swift rebound of the Company. o Achieve a better financial strength rating: Converium's management is in regular contact with the rating agencies. Restoring their confidence based on a stable financial performance remains a key corporate priority. o Implement future business strategies: Encouraged by the robustness of its franchise, Converium will enter the upcoming January 2006 renewal negotiations with the self-confidence of a knowledge-based, client-centric and nimble multi-line reinsurer offering a clear geographic focus. o Successfully manage the run-off of CRNA: The Company remains committed to reducing legacy exposure from the US business in a way that meets the interests of shareholders. Converium will continue to diligently pursue commutations, look into the option of selling CRNA and constantly evaluate any other options for extracting maximum value for shareholders from the US business. Business development Standard Property & Casualty Reinsurance reported segment income of US$ 32.5 million for the second quarter and US$ 34.9 million for the first half of 2005, compared to US$ 22.0 million and US$ 69.0 million for the same periods of 2004, respectively. The segment results were primarily attributable to a solid underwriting performance, supported by net positive development of prior years' loss reserves of US$ 3.3 million in the first half of 2005 and to the absence of major catastrophic events in the second quarter of 2005. For the second quarter of 2005, the segment recorded a net strengthening of prior years' loss reserves of US$ 6.9 million, primarily related to a strengthening within the Motor line of business (US$ 17.9 million), which was partially offset by positive development within the Property line of business (US$ 17.6 million). The development in Property business includes a strengthening of US$ 4.4 million related to the US / Caribbean hurricanes that occurred in late 2004. For the second quarter 2005, the loss ratio remained relatively flat as compared to the same period of 2004. The impact of winter storm Erwin, which resulted in net pre-tax losses in the amount of US$ 32.5 million during the first quarter of 2005, added 7.7 percentage points to the loss ratio for the first half of 2005. The combined ratio was 120.7% (including an administration expense ratio of 28.6%) for the second quarter of 2005 and 105.0% (including an administration expense ratio of 7.0%) for the first half of 2005, compared to 103.6% and 97.1% for the same periods of 2004, respectively. In the second quarter of 2005, gross premiums written decreased 83.2% to US$ 47.9 million, net premiums written declined 83.0% to US$ 43.3 million (representing approximately 13.1% of total net premiums written) and net premiums earned decreased 46.5% to US$ 178.9 million, compared to the same period of 2004. In the first half of 2005, gross premiums written dropped 49.9% to US$ 460.4 million, net premiums written decreased 47.8% to US$ 446.2 million (representing approximately 43.1% of total net premiums written), and net premiums earned declined 40.4% to US$ 420.9 million, compared to the same period of 2004. The premium volume in 2005 was impacted by the ratings downgrades that occurred in 2004, which resulted in clients canceling their business or reducing their shares with Converium. In addition, due to the seasonality involved with the renewal of its business in different markets, Converium generally records the largest share of its premium volume in the first quarter of a given year and approximately half of the annual premium volume by the end of the second quarter of a given year. In the first half of 2005, the reduction in net premiums written by line of business included: o Motor, which decreased by 60.7% or US$ 195.1 million to US$ 126.5 million; o Property, which declined by 14.1% or US$ 42.9 million to US$ 262.0 million; o General Third Party Liability, which dropped by 76.7% or US$ 147.9 million to US$ 44.5 million, also due to revisions to premium estimates on our London Market North America and United Kingdom book of business; and o Personal accident business assumed from non-life insurers, which decreased by 54.7% or US$ 14.1 million to US$ 11.7 million. Specialty Lines reported a segment income of US$ 41.3 million for the second quarter and US$ 11.7 million for the first half of 2005, compared to a segment loss of US$ 10.6 million and segment income US$ 37.4 million for the same periods of 2004, respectively. The segment results were primarily attributable to a solid underwriting performance, supported by net positive development of prior years' loss reserves of US$ 10.5 million in the second quarter of 2005, which was primarily driven by positive development within the Aviation line of business (US$ 19.5 million) and partially offset by net strengthening within other lines of business of the segment. For the first half of 2005, Converium recorded net positive development of prior years' loss reserves of US$ 6.4 million. The segment result also benefited from the absence of major catastrophic events in the second quarter of 2005. The result for the first half of 2005 has also been affected by the commutation of certain retrocession contracts, which had a negative impact on losses of US$ 38.7 million during the first quarter of 2005. For the second quarter the combined ratio was 99.6% (including an administration expense ratio of 5.1%) and 111.6% (including an administration expense ratio of 7.4%) for the first half of 2005, compared to 115.1% and 105.1% for the same periods of 2004, respectively. In the second quarter of 2005, gross premiums written decreased 34.1% to US$ 247.3 million, net premiums written declined 33.9% to US$ 229.5 million (representing approximately 69.3% of total net premiums written) and net premiums earned increased 9.0% to US$ 327.3 million, compared to the same period of 2004. In the first half of 2005, gross premiums written decreased 44.4% to US$ 401.8 million, net premiums written declined 42.6% to US$ 384.9 million (representing approximately 37.2% of total net premiums written), and net premiums earned increased 6.4% to US$ 619.7 million, compared to the same period of 2004. The premium volume in 2005 was impacted by the ratings downgrades that occurred in 2004, which resulted in clients canceling their business or reducing their shares with Converium. In the first half of 2005, the reduction in net premiums written by line of business included: o Aviation & Space, which decreased by 31.5% or US$ 59.8 million to US$ 129.9 million; o Credit & Surety, which dropped by 69.2% or US$ 69.4 million to US$ 30.9 million; o Professional Liability and other Special Liability, which decreased by 45.5% or US$ 97.6 million to US$ 116.8 million; o Engineering, which fell by 39.6% or US$ 29.6 million to US$ 45.2 million; o Marine & Energy, which decreased by 25.8% or US$ 13.9 million to US$ 40.0 million; and o Workers' Compensation, which declined by 97.3% or US$ 33.2 million to US$ 0.9 million. These decreases were offset by an increase in net premiums written in the Agribusiness line of business, which grew by US$ 4.2 million to US$ 21.2 million. Additionally, in Specialty Lines, Converium successfully renewed the significant business with its strategic partner, the Medical Defence Union (MDU). Life & Health Reinsurance reported a segment income of US$ 0.3 million for the second quarter and US$ 6.5 million for the first half of 2005, compared to US$ 1.9 million and US$ 3.4 million for the same periods of 2004, respectively. The technical result was US$ 1.5 million for the second quarter of 2005 and US$ 8.1 million for the first half of 2005, compared to US$ 4.1 million and US$ 5.4 million for the same periods in 2004, respectively. It is defined as net premiums earned minus losses, loss adjustment expenses and life benefits minus underwriting acquisition costs plus technical interest. The decrease in segment income and technical result for the second quarter of 2005 was primarily driven by Converium's decision to non-renew two large contracts as well as updated cedent information pertaining to our European and Latin American markets. The increased segment income in the first half of 2005 was primarily attributable to the expansion of existing reinsurance transactions in Continental Europe but was partially offset by negative loss development of US$ 1.5 million in the first quarter of 2005 related to the tsunami that occurred in late 2004. In the second quarter of 2005, gross premiums written decreased 16.0% to US$ 59.3 million, net premiums written fell 2.6% to US$ 55.7 million (representing approximately 16.8% of total net premiums written), and net premiums earned decreased 11.4% to US$ 74.1 million, compared to the same period of 2004. For the first half of 2005, gross premiums written decreased 7.1% to US$ 176.4 million, net premiums written increased 0.7% to US$ 169.5 million (representing approximately 16.4% of total net premiums written), and net premiums earned increased 2.6% to US$ 155.2 million, compared to the same period of 2004. In the first half of 2005, the growth of net premiums written in the Life & Health Reinsurance segment primarily occurred in Life and Disability reinsurance, which increased by 8.5% or US$ 10.3 million to US$ 132.2 million, and is largely reflective of the expansion of existing reinsurance transactions as well new business being written. This increase was offset by a decrease of 4.9% or US$ 2.0 million in net premiums written to US$ 38.5 million in the Accident and Health line of business due to the cancellation of contracts where the overall performance was not in-line with Converium's profitability targets as well as to the impact of the ratings downgrades that occurred in 2004. The Run-Off segment represents all non-life and life business originating from CRNA and Converium Insurance (North America) Inc., excluding the US-originated aviation business portfolio. The Run-Off segment reported a segment income of US$ 6.9 million for the second quarter and US$ 2.3 million for the first half of 2005, compared to US$ -289.6 million and US$ -284.2 million for the same periods of 2004, respectively. In the second quarter of 2005 the segment recorded US$ 3.1 million of net positive development of prior years' loss reserves, which resulted in net strengthening of prior years' loss reserves of US$ 13.3 million in the first half of 2005. In the second quarter of 2004 the Run-Off segment strengthened its prior years' loss reserves by US$ 331.3 million, primarily within the Professional Liability and other Special Liability and General Third Party Liability lines of business, which resulted in US$ 397.4 million of net reserve strengthening of prior years' loss reserves in the first half of 2004. The Corporate Center carries certain administration expenses, such as costs of the Board of Directors, the Global Executive Committee and other corporate functions as well as other expenses not allocated to the operating segments. The Corporate Center reported costs of US$ 11.8 million for the second quarter and US$ 19.0 million for the first half of 2005, compared to US$ 7.4 million and US$ 17.1 million for the same periods of 2004, respectively. The increase in the first half of 2005 as compared to the same period of 2004 was due to increased consulting fees related to Converium's organizational and operational restructuring. * * * * * * * Converium 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 continue to provide investors with perspectives on its value drivers, its strategic initiatives and those factors critical to understanding its business and operating environment.
