FINAL REPORTS CONFIRM WINTERTHUR WINS THE DISPUTE WITH XL REGARDING THE 
SEASONED NET RESERVES AMOUNT AND THE SEASONED NET PREMIUM RECEIVABLE AMOUNT.

Zurich, December 6, 2005 - CREDIT SUISSE GROUP TODAY ANNOUNCED THAT THE 
INDEPENDENT ACTUARY DESIGNATED IN THE SALE AND PURCHASE AGREEMENT (SPA) 
BETWEEN XL INSURANCE (BERMUDA) LIMITED ("XL") AND WINTERTHUR SWISS INSURANCE 
COMPANY ("WINTERTHUR") REGARDING THE SALE OF WINTERTHUR INTERNATIONAL IN 
2001, HAS RELEASED THE FINAL REPORTS REGARDING THE ESTIMATES OF THE SEASONED 
NET RESERVES AMOUNT AND THE SEASONED NET PREMIUM RECEIVABLE AMOUNT.

The Independent Actuary's Final Reports confirm the results of the Draft 
Reports released on November 24, whereupon the Independent Actuary's 
conclusions of the reserve liability and the seasoning of premiums received 
by XL are closer to the estimates submitted by Winterthur. Accordingly, 
Winterthur's estimates have become the final and relevant Seasoned Net 
Reserves Amount and Seasoned Net Premium Receivable Amount. The Seasoning 
Process can now be considered completed.

The provisions recorded by Winterthur on September 30, 2005 for this 
sale-related contingency, net of pre-payments to and risks retained by XL, 
amounted to USD 541 million plus interest accrued between June 30, 2004 and 
September 2005. The final payment to XL will include further interest up to 
settlement date, and a USD 6 million increase agreed by both parties in the 
fourth quarter 2005. The Independent Actuary's conclusion regarding the 
Seasoned Net Premium Receivable Amount will result in a USD 9 million payment 
from XL to Winterthur.

that a number of important factors could cause results to differ materially 
from the plans, objectives, expectations, estimates and intentions expressed

our operations; (vii) the ability to maintain sufficient liquidity and access 
capital markets; (viii) operational factors such as systems failure, human 
error, or the failure to properly implement procedures; (ix) actions taken by 
regulators with respect to our business and practices in one or more of the 
countries in which we conduct our operations; (x) the effects of changes in 
laws, regulations or accounting policies or practices; (xi) competition in 
geographic and business areas in which we conduct our operations; (xii) the 
ability to retain and recruit qualified personnel; (xiii) the ability to

acquisitions, including the ability to integrate successfully acquired 
businesses; (xviii) the adverse resolution of litigation and other 
contingencies; and (xix) our success at managing the risks involved in the 
foregoing.  We caution you that the foregoing list of important factors is 
not exclusive; when evaluating forward-looking statements, you should
