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 23, 2004 - Converium informs on the Extraordinary General Meeting (EGM) to be held on September 28, 2004 Converium considering a range of strategic options Following a careful examination of the Company's track record and franchise outside the United States, the Board of Directors of Converium believes that the Company has a viable business future as a professional reinsurer. In this context, Converium is considering a range of strategic options, which include a capital increase, a partnership, a strategic investment, or a combination thereof. Non-US franchise historically a strong source of earnings Converium has a track record of building profitable businesses in key 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. The Company believes that despite the set backs suffered in the United States, it continues to enjoy a strong and stable franchise among its customers in the remaining markets. An independent survey from Flashpoehler conducted in the first half of 2004 among European cedents indicates that Converium's clients rank the Company 3rd in terms of overall excellence among all reinsurers surveyed. Against this backdrop Converium's Board of Directors believes that the Company can continue to extract value from this franchise for the benefit of shareholders. As a consequence, a going concern on a stand-alone basis based on a capital increase remains a viable option. Converium is committed to maintain maximum flexibility as regards strategic options In considering all options to protect the Company's franchise and shareholders' value, flexibility is an essential component of this process. A capital increase is a core ingredient in a number of these options. Converium is currently discussing a partnership or strategic investment with various parties. While some discussions are at a more advanced stage, additional time will be needed in order to diligently evaluate and compare all options when it comes to structures and terms. The progress of a number of discussions is dependent on assurances to the potential partners that the capital increase will be available. Converium's Board of Directors stresses that the Company will only execute a capital increase that makes sense from a shareholder value and rating perspective and on underwriting terms that are acceptable to the Company. The Board of Directors is proposing a flexible capital increase structure to the EGM Against this backdrop, the Board of Directors proposes that shareholders approve a capital structure allowing a capital increase of up to $420 million for o a discounted rights issue for existing shareholders and, if appropriate, o a tranche for a strategic investment or partnership for which pre-emptive rights are excluded. Board of Directors seeks shareholder approval of the proposed capital increase While the Board of Directors appreciates that several questions may remain outstanding, having the capital increase approved will give the Company the necessary flexibility to effectively evaluate all options. Not having approval will restrain Converium's strategic and tactical flexibility and may ultimately force the Company to consider alternatives which may not result in achieving an outcome that generates the best value for shareholders. * * * * * * * Converence call details Converium will hold a conference call for the investment community and is pleased to invite you to participate.
