Prospectus Supplement No. 1 dated May 4, 1999 Rule 424(b)(3) To Prospectus dated August 14, 1998 File No.:333-60985 14,328,010 Shares ACE LIMITED Ordinary Shares (par value 0.041666667) This Supplement No. 1 supplements the information contained in the prospectus of ACE Limited, a Cayman Islands company, dated August 14, 1998. This Supplement No. 1 adds selling shareholders who were not named in the prospectus. ACE has been informed by Insurance Partners Charman (Bermuda), L.P., a Bermuda limited partnership ("IPC"), and Insurance Partners Offshore (Bermuda), L.P., a Bermuda limited partnership ("IPO"), that they intend to make pro rata distributions (the "Distributions") of an aggregate of 7,952,613 ordinary shares to their direct and indirect partners (each a "Partner"). The 7,952,613 ordinary shares represent all of the ordinary shares registered on behalf of IPC and IPO in the prospectus. The following table sets forth the names of the Partners offering ordinary shares under the prospectus, the estimated number of ordinary shares to be beneficially owned by each such Partner after giving effect to the Distributions and the number of ordinary shares which may be offered for sale pursuant to the prospectus by each such Partner. ACE has been informed by IPC and IPO that none of the Partners has held any position, office or other material relationship with ACE or any of its affiliates within the past three years other than as a result of his, her or its ownership of ordinary shares (or securities convertible into or exercisable for ordinary shares). None of the figures below for any selling shareholder individually represents 1% or more of ACE's outstanding ordinary shares. The ordinary shares listed in the following table may be offered from time to time by the Partners named below. However, such Partners are under no obligation to sell all or any portion of such ordinary shares, nor are the Partners obligated to sell any such ordinary shares immediately under the prospectus. The actual number of ordinary shares that will be beneficially owned by each Partner after giving effect to the Distributions may differ from the numbers listed below. In addition, although the total estimated number of ordinary shares to be distributed to the Partners listed in the table below may exceed the total number of ordinary shares held by IPC and IPO, the actual number of ordinary shares to be distributed to the Partners will not. Because the Partners may sell all or part of their ordinary shares, no estimate can be given as to the number of ordinary shares that will be held by any Partner upon termination of any offering made hereby.
