~~The~~As ~~Offer~~part ~~may~~of bethe ~~accepted~~additional ~~from~~acceptance ~~June~~period of SCOR’s public offer for Converium’s publicly held shares (“the Offer”), which opened on July 1213, 2007 ~~until~~and was closed on July 926, 2007, ~~subject~~14,905,395 additional Converium shares have been tendered to ~~extension~~the inOffer, ~~accordance~~i.e. 10.16% of Converium shares, of which 3,732,335 Converium shares are in the process of being confirmed. Together with the 48,320,350 ~~provisions~~Converium shares already owned by the SCOR Group and the 77,937,316 Converium shares tendered during the initial period of the Offer, ~~Prospectus~~SCOR would hold 96.23% (~~see~~93.69% ~~indicative~~excluding ~~timetable~~the Converium shares in the process of being confirmed) of Converium’s share capital in the aggregate. The definitive final result of the Offer will be published on August 2, 2007.

1.Subject Ato ~~very~~the ~~attractive~~applicable ~~offer~~conditions subsequent set forth in the Offer prospectus published on April 5, 2007, as amended on June 12, 2007, the settlement and delivery of the Offer is scheduled to take place on August 8, 2007.

SCOR considers that the proposed terms of this Offer are very attractive to Converium shareholders and notes that the friendly and recommended nature of the transaction significantly reduces the execution risks of this combination.

Based on the closing price of SCOR Shares on May 9, 2007:

—		The Offer Price is adjusted by 7.9% and takes into account the increase in Converium’s net asset value in Q1 2007
—		The Offer Price represents a significant premium to Converium shareholders:

→ 39% premium on last unaffected share price (4 January 2007)

→ 27% and 32% premium on respective 1-month and 3-month average prior to the announcement of block acquisitions (16 February 2007)

2. A compelling business rationale

The Group which will combine SCOR and Converium will become one of the top choices for clients in key markets. It will capitalise on a comprehensive network structured around hubs with three key European locations Paris, Zurich and Cologne, plus 2 major hubs for Asia and for the Americas. It will also benefit from an enlarged pool of talents and competencies and an increased diversified offering by market and business line. This combination is also predicated on manageable overlaps between the books of business of the two companies. Improved market presence and proactive cycle management is expected to deliver sustainable growth.

The combination of Converium and SCOR will create a Top 5 global multi-line reinsurance company in terms of pro forma gross written premiums, based on very solid foundations:

— Premium income in the range of EUR 5.5 billion; — Market capitalisation in the range of EUR 3.7 billion; — Long term capital base in the range of EUR 4.8 billion; — Leading positions in Europe in most lines of business and leading global market positions in selected areas such as life reinsurance, specialty lines, large facultative accounts and treaties; — Well diversified sources of revenues between life and non-life lines, providing reduced earnings volatility and improved risk profile; — Strong position to efficiently manage cycle thanks to a wider spectrum of business lines and services; — Value enhancing combination of recognised pools of talents from both organisations focused on innovation and tailor-made solutions for clients and better able to adapt to today’s risk environment; — EUR 65 million of estimated annual pre-tax cost synergies from 2009 onwards; — Maximum diversification benefit according to Solvency II requirements; — State-of-the-art Enterprise Risk Management (ERM).

The transaction will have a significant positive impact for SCOR shareholders. It should result in a single digit EPS accretion as soon as 2008 and a double digit EPS accretion in 2009 based on the “Dynamic Lift” assumptions.

-3-

SCOR strongly believes that this combination is beneficial for all stakeholders. Clients and brokers will gain access to a new top-choice risk carrier, an enlarged and innovative product mix, a reinforced security level and an expanded network. Employees will benefit from enhanced opportunities. The combination is also expected to create substantial value for both companies’ shareholders as the benefits of the combination are realised.

3. A clear strategic vision and reduced execution risks

The Dynamic Lift V1 plan, published on 4 April 2007 and designed for the Group that will result from the combination of SCOR and Converium, sets out the strategic vision behind the creation of the fifth largest global multi-line reinsurer benefiting from all the advantages that scale and scope bring.

It underscores the industrial rationale inherent to this combination that accelerates SCOR’s proven strategy over the last three years. The new Group will constitute a leading risk carrier and price maker with reinforced market positions in Europe and in lines of business such as Specialty Lines and European Treaty, where the Group has competitive advantages.

The new Group will have the necessary size to derive maximum benefit on its capital base thanks to its large diversification, especially when considered in the context of the upcoming Solvency II regulatory framework.

The Dynamic Lift plan is predicated upon the trends towards higher capital requirements, a realistic assessment of insurance and reinsurance market developments and a stable financial environment. Under these reasonable assumptions, the financial model underpinning the Dynamic Lift plan aims at three key targets:

(i) an A+ level of security by 2010; (ii) an RoE of 900 bps above the risk free rate over the cycle; (iii) Internally generated capital resources needed to finance the development of the Group over the cycle.

As part of the friendly combination process of the two groups, the Dynamic Lift V1 plan will be enriched, detailed and refined with Converium’s management and the resulting Dynamic Lift V2 plan will be presented early September.

4. The integration process is underway

Subject to compliance with applicable antitrust laws, two key joint-committees with equitable representation have been set up and have already been convened : an Integration Committee and an Underwriting Committee.

The Underwriting Committee comprises seven different workgroups:

— Life underwriting — Non-Life underwriting — London-based joint-ventures — Pricing and reserving — Claims and commutations — Retrocession and Cat Bond — Capital allocation

The Integration Committee comprises seven different workgroups:

— Organizational and legal structures — Compliance, audit and governance — IT — Finance — Asset Management — Human Resources — Communication

The integration process is focused on offering a seamless interface to all our clients and a common underwriting plan for the 2008 renewals. The new underwriting plan will be presented before the Monte-Carlo Rendez-Vous scheduled on 10 September 2007.

The Swiss Takeover Board pretends in its Recommendation IV that SCOR has acted in concert with Martin Ebner and all persons and other legal entities directly or indirectly controlled by him with respect to the Offer at the latest as from the execution of the Share Purchase Agreement with Patinex dated February 16, 2007. SCOR entirely refutes this allegation. SCOR reserves the right to file an appeal in accordance with the applicable legal and regulatory provisions but has decided not to delay the opening of the Offer. SCOR considers that the characterization of such an action in concert by the Swiss Takeover Board should not have any impact on the Offer itself.

Denis Kessler, SCOR Chairman and Chief Executive Officer, said:

“The opening of the Offer is excellent news. Converium shareholders now have a solid offer, which provides full value for their company. The agreement concluded with the Board of Directors and the management of Converium is an essential contribution for a rapid integration of the two groups and for the implementation of a common underwriting policy as soon as the 2008 renewals.

I am very pleased to note the strong mobilization of Converium and SCOR teams to realize this exciting project which will create the fifth largest reinsurance group in the world. This project will create value by reinforcing the competitive position of the new group, by deepening its expertise and competencies, by raising the level of its risk management and by widening its degree of diversification.

On behalf of the Board of Directors of SCOR I would like to heartily invite all the shareholders of Converium to support this important project by tendering their shares to the Offer that opens today.”

Exhibit 99-2

18 june, 2007

SCOR American Depositary Shares delisted June 14, 2007

SCOR announces that its American Depositary Shares (ADSs) were delisted on June 14, 2007 from the New York Stock Exchange, following the company’s application for voluntary delisting filed on June 4, 2007. As of June 14, 2007, SCOR’s American Depositary Receipt program has also transitioned to Level I status, and SCOR’s ADSs may now be traded on the Over-The-Counter Market.

SCOR has decided to apply for a secondary listing on the SWX Swiss Exchange upon consummation of the public tender offer for all publicly held registered shares of Converium Holding AG.

This decision by SCOR to delist from the New York Stock Exchange and to terminate the registration of its securities under the US Securities Exchange Act of 1934, in line with many other European and other issuers, was motivated by both cost and liquidity considerations and was taken in the interest of all of SCOR shareholders.

SCOR’s rationale for delisting and deregistration is based on the following:

— The primary market for SCOR’s shares is Euronext (now part of NYSE-Euronext), where the average trading volume has accounted for more than 97% of SCOR’s worldwide trading volume over the last three years; — SCOR’s ADS trading volume has declined over the past three years and has accounted for approximately 1% of the total volume of shares traded over the last year (adjusted to reflect SCOR’s January 2007 ten-for-one reverse share split); — SCOR adopted International Financial Reporting Standards (IFRS) in 2005. The Company believes that U.S. GAAP and IFRS are generally equivalent in terms of disclosure and quality of information for investors and that it is unnecessary to publish its accounts under the two reporting standards. — SCOR is continuously seeking to optimize its operating costs.

The delisting and deregistration will have no impact on SCOR’s primary listing of its ordinary shares on Eurolist by Euronext. SCOR will continue to publish English language financial reports, financial statements, press releases and shareholder information, which will be available on its web site (www.scor.com) in accordance with Rule 12g3-2(b) under the U.S. Securities Exchange Act of 1934.

SCOR considers that U.S. investors are an important part of its investor base and will maintain its relationship with them, as well as maintaining and continuing to develop its business operations in the United States. The Company will continue to provide a high standard of corporate governance, information and disclosure for all investors, including those in the United States.
