Prospectus Supplement No. 3 dated June 21, 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. 3 supplements and, to the extent inconsistent therewith, amends the information contained in the prospectus of ACE Limited, a Cayman Islands company, dated August 14, 1998 as supplemented by Prospectus Supplement No. 1 dated May 4, 1999, Prospectus Supplement No. 1 (Revised) dated May 4, 1999 and Prospectus Supplement No. 2 dated May 10, 1999. We have 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 have made pro rata 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. As described in Prospectus Supplement No. 2 dated May 10, 1999, a total of 2,315,483 of these ordinary shares were sold by the Partners named therein to J.P. Morgan Securities Inc., as underwriter. The following table sets forth the name of each selling shareholder, the number of ordinary shares beneficially owned by each selling shareholder and the number of ordinary shares offered hereby. We have been informed by the selling shareholders that, except as set forth in the footnotes to the table, none of the selling shareholders has held any position, office or other material relationship with us or any of our 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 our outstanding ordinary shares. The ordinary shares listed in the following table may be offered from time to time by the selling shareholders named below. However, such selling shareholders are under no obligation to sell all or any portion of such ordinary shares, nor are the selling shareholders obligated to sell any such ordinary shares immediately under the prospectus. Because the selling shareholders 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 selling shareholder upon termination of any offering made hereby. 1 Ordinary Shares Beneficially Owned Ordinary Shares Name of Selling Shareholder Prior to Offering Offered Hereby - --------------------------- ------------------ --------------- Aon Corporation (1) 318,282 318,282 Sheikh Abdulrahman Ali Al-Turki 122,200 122,200 American States Insurance Company 63,656 63,656 Arab Investment and Management Corporation 122,200 122,200 Chris Argyyris 611 611 Glenn R.
