FOR IMMEDIATE RELEASE EXHIBIT 99.1 Investor Contact: Helen M. Wilson (441) 299-9283 Media Contact: Wendy Davis Johnson (441) 299-9347 HAMILTON, Bermuda--(BUSINESS WIRE)--Jan. 8, 2002--ACE Limited (NYSE:ACE) today announced that its fourth quarter net operating income will fall below expectations due to an increase of approximately $80 million, after taxes, in property losses incurred in its European Commercial Property portfolio together with a $50 million charge taken to strengthen loss reserves principally in its International Casualty Operations. Mr. Brian Duperreault, Chairman and Chief Executive Officer, said: "We experienced a pattern of increased frequency and severity within our European Commercial Property portfolio. In response to these adverse results we have tightened underwriting controls and significantly increased prices. We believe the changes made will permit us to realize our financial objectives for this unit in 2002. We also carefully reviewed the development of our international casualty portfolio and determined an increase in reserves was warranted. The balance of our business segments have performed as expected and we do not expect the issues affecting the fourth quarter to carry forward into the new year." ACE Limited expects to report its quarterly earnings before the opening of business on Wednesday, February 13, 2002. ACE management will then provide its customary supplemental commentary in a conference call and webcast scheduled for 9:30 a.m. EST on the same date. The ACE Group of Companies provides insurance and reinsurance for a diverse group of clients. The ACE Group conducts its business on a global basis with operating subsidiaries in nearly 50 countries.
