Media Release

Credit Suisse Group sells Winterthur to AXA

Zurich, June 14, 2006 Credit Suisse Group today announced that it has entered into a definitive agreement for the sale of Winterthur Swiss Insurance Company (“Winterthur”), its insurance business, to AXA for a cash consideration of CHF 12.3 billion. AXA will acquire 100% of Winterthur. The transaction is subject to customary regulatory approvals and closing conditions and is expected to close around year-end 2006.

Walter B. Kielholz, Chairman of Credit Suisse Group, said: “During the last three years, Winterthur has steadily improved its operating performance and delivered an impressive turnaround. We are therefore able to deliver the full value of Winterthur to our shareholders through this transaction. Credit Suisse Group is now in a position to focus its management and capital resources on its core banking businesses.”

Leonhard H. Fischer, CEO of Winterthur, said: “The sale of Winterthur to AXA is a significant step for the clients and employees of Winterthur as well as for the Swiss market. Having reviewed several strategic options for the future of Winterthur, the management team of Winterthur is convinced that by joining AXA, Winterthur’s businesses will be best positioned for future growth. We also believe that the clients and employees of Winterthur will benefit in the long term from being part of one of the global leaders in the insurance industry with an excellent reputation among its stakeholders.”

Henri de Castries, Group CEO of AXA, said: “This transaction is a unique opportunity to reinforce our leading position in our core European market and to increase our presence in emerging markets, notably in Eastern Europe and in Asia. The complementarity of our organizations and the strong cultural fit between our teams will facilitate the integration of Winterthur and will drive value creation for our shareholders. I am confident that Winterthur’s professionals will contribute very positively to our company.”

The sale of Winterthur follows Credit Suisse Group’s decision in 2004 to focus its growth strategy on an integrated global banking business model. For the past two years, Credit Suisse Group has been managing Winterthur as a financial investment and preparing it for a capital market transaction.

Under the terms of the transaction, Credit Suisse Group will receive a cash payment of CHF 12.3 billion. This consideration is equivalent to 1.6 times Winterthur’s Group European Embedded Value(1) of CHF 7.9 billion as of December 31, 2005. Furthermore, AXA will redeem GBP 500 million (approximately CHF 1.1 billion) of intercompany hybrid debt currently outstanding between Credit Suisse Group and Winterthur. In the context of the sale, Credit Suisse Group has granted AXA customary representations and warranties and has not provided any indemnification in respect of Winterthur’s insurance reserves.

Credit Suisse Group expects to record a gain from the sale of Winterthur. The actual gain on sale will be dependent upon the accrued book value of Winterthur at the time of closing. As of March 31, 2006, Winterthur had a carrying value in Credit Suisse Group’s accounts of CHF 9.4 billion. Excluding any gain on sale and assuming the deconsolidation of Winterthur, Credit Suisse Group would have reported a tier 1 ratio and total capital ratio of 13.0% and 17.8% respectively, as of March 31, 2006.

Oswald J. Grübel, CEO of Credit Suisse Group, said: “We plan to reinvest the proceeds from the sale of Winterthur in the development of our banking businesses. Our growth plans are focused on organic growth opportunities and selected acquisitions and joint ventures in our investment banking, private banking and asset management businesses. However, we have no intention of making any transforming acquisitions.”

He continued: “Credit Suisse Group is committed to maximizing returns for its shareholders. We will invest the capital from the sale of Winterthur to compensate for the loss of earnings. We confirm our net income target for 2007 of CHF 8.2 billion, assuming a stable market environment. Any excess capital that cannot be used to grow our business will be returned to our shareholders.”

Credit Suisse Group’s current share buyback program of up to CHF 6 billion will be continued and is expected to be completed in the first half of 2007. This program takes into account the impact from the introduction of Basel II, which, based on current modeling and business mix, would increase the tier 1 capital requirement by approximately 150 basis points.

Credit Suisse Group is being advised by its Investment Banking division. Evercore Partners has provided an opinion to the Board of Directors of Credit Suisse Group on the fairness of the transaction.
