CONVERIUM HOLDING AG By: /s/ Dirk Lohmann Name: Dirk Lohmann Title: CEO By: /s/ Christian Felderer Name: Christian Felderer Title: General Legal Counsel Date: September 27, 2004 Converium Holding Ltd, Zug Zug, Switzerland - September 27, 2004 - Converium committed to raising capital After considering various options and following today's announcement from Standard & Poor's indicating its intention to upgrade Converium to a BBB+ financial strength rating, subject to the successful completion of a US$ 420 million capital increase, Converium's Board of Directors reaffirms its proposal to the Extraordinary General Meeting (EGM) to approve an increase in ordinary capital on a with-rights basis in the CHF equivalent of US$ 420 million. The Board believes that such a share issue will maximize shareholder value. The commitment to raising additional capital is based on Converium's strong non-US franchise, the continuing support from cedents and brokers and the Company's well-established direct distribution platform. In order to draw a line under its US legacy issues Converium is also examining the possibility of a sale of its US-based subsidiary. Converium will proceed with the proposed with-rights capital increase At the EGM on September 28, 2004 shareholders will be asked to approve a share issue in the CHF equivalent of US$ 420 million with pre-emption rights for all existing shareholders. This capital increase is expected to be fully underwritten by a banking syndicate at the terms and conditions, which will be announced prior to the EGM. Converium is pleased with today's announcement by Standard & Poor's. The Board of Directors therefore believes that the proposed capital increase is the best way of protecting the value of Converium's non-US franchise and the embedded value of the Company's business for shareholders. Following an analysis of other options such as a trade sale, a sale to a financial investor, participation by a strategic investor or a run-off, the Board of Directors believes that Converium as a going concern, possibly in conjunction with a sale of its US operations, will maximize shareholder value. Strong franchise and high level of broker and client support outside the US Converium has a track record of building profitable businesses in key regional markets such as Europe, Asia-Pacific and Latin America. Since Converium's Initial Public Offering (IPO) the Company has generated net income in excess of US$ 500 million excluding business underwritten by the North American entity. Converium believes that despite the setbacks suffered in the United States, it continues to enjoy a strong and stable franchise among its customers in the remaining markets. This franchise is founded upon Converium's financial strength, its direct distribution platform which provides access to profitable business, the quality of its client relationships and intellectual capital. A recent independent survey from Flaspohler Research Group conducted in the first half of 2004 among European cedents indicates that Converium's clients rank the Company third in terms of overall excellence among all reinsurers surveyed. The foundations of some of these client relationships have been in place and enriched over the past 20 years. The Flaspohler survey also demonstrates primary insurers' desire for choice and diversification when entering into a reinsurance transaction. Given the limited number of professional reinsurers with direct distribution capabilities, clients and brokers in many markets have recently reiterated strong support for Converium in its intention of continuing to write business. North America: Tough decisions taken to protect shareholder value As announced on September 10, 2004 Converium will place its US operations into run-off. The Company will discontinue the writing of reinsurance from offices located in North America. However, Converium will offer reinsurance for attractive US-originated business to select US-based clients. This business will be underwritten and managed through Converium AG, Zurich, and its Bermuda branch. Converium believes that this resolute course of action represents the best option for the Company's shareholders. In order to draw a line under its US legacy issues Converium is also examining the possibility of a sale of its US-based subsidiary. Converium's future shape and priorities as a stand-alone entity Reduction of top-line due to geographic realignment and focus on target clients Going forward, Converium will focus on markets where its franchise remains strong, i.e. Europe, Asia and Latin America. The Company will seek to capitalize on its successful record of building a profitable market position in these regions. In general, Converium will focus on small and medium-sized clients who have limited access to capital markets and rely on additional services from their reinsurers, such as reinsurance structuring advice and risk modelling capabilities. Among this target group of clients are mutuals, cooperatives, public body insurers, regional insurers and specialist insurers. Based on market research the Company believes that these carriers place a greater weight on relationship orientation than other reinsurer selection criteria. Accordingly, in order to enhance its position with these clients Converium will continue its successful Client Relationship Management (CRM) strategy launched in 2001 prior to the IPO. Given the discontinuation of local underwriting in the US, Converium's North American business will be reduced by US$ 1.0 billion or more for underwriting year 2005, predominantly in Standard Property & Casualty Reinsurance and Specialty Lines. In Europe, Asia-Pacific and Latin America Converium's writings will reduce to a sustainable level. Currently the Company expects its non-US premium volume for underwriting year 2005 to be reduced by up to 40% compared to 2004 mainly because of the lower ratings but also due to Converium's continued stringent target returns for underwriting. Accordingly, Converium's preliminary estimates are that in underwriting year 2005, total gross written premiums will be in the order of half the total for 2004. The Company expects profitable growth to resume in 2006. Further development and reinforcement of strategic alliances Converium will continue to reinforce and develop its joint venture relationships such as Global Aerospace Underwriting Managers Ltd (GAUM) in global aviation insurance, Satec in global space insurance, the Medical Defence Union (MDU) in UK medical malpractice insurance and Converium's corporate name at Lloyd's (Converium Underwriting Ltd.). In 2003, these operations accounted for premium income of more than US$ 600 million. These source-controlled businesses are either not rating-sensitive or Converium will seek to secure them through suitable fronting arrangements currently under negotiation. Underwriting results no longer affected by US legacy issues Converium has resolutely addressed its North American reserving deficiencies. Going forward, the Company's profitable non-US record is no longer expected to be impaired by reserve shortfalls in the US. Converium also emphasizes that, irrespective of the recent rating decisions, its commitment to a strict underwriting discipline will be maintained. In addition, the Company will adjust its cost base to the reduced top-line in order to remain cost-competitive. Investment results expected to remain strong Converium's total invested assets plus cash amount to almost US$ 8 billion. The Company's conservative asset allocation is driven by Asset and Liability Management considerations. It is expected to continue to generate strong investment results. Aim for a stronger financial strength rating within a reasonable time frame In order to preserve its economic value Converium will seek to restore a strong financial strength rating within a reasonable time frame. The Company believes that its portfolio, following the recent reserve strengthening, has a strong embedded earnings potential. Converium regards this, in conjunction with a strong capital adequacy following a successful share issue, as the foundation upon which a restoration of a higher rating will be based. Active management of capital base Converium aims at generating attractive returns on capital. If capital cannot be fully deployed in future periods Converium will consider returning such capital to shareholders. At the same time, the Company is committed to maintaining its capital at a level that is consistent with an "A"-level rating. Peter C. Colombo, Chairman of the Board of Directors, said: "Having reviewed various strategic options the Board of Directors has concluded that the proposed capital increase is the best option for Converium's shareholders. There is evidence, further validated today by Standard & Poor's announcement, that our non-US franchise continues to be profitable in our chosen markets and our clients want Converium to stay in business as an independent company." Dirk Lohmann, CEO, added: "We firmly believe that our revised strategy lays the foundation for a profitable and sustainable future as a going concern. There have been shortcomings in North America but we have taken resolute actions in order to allow Converium's profitable non-US track record and strong franchise to maximize future shareholder value."
