("AIG") amends Item 4 of AIG's Statement on Schedule 13D (the "Statement") originally filed by AIG on April 9, 1996 and as amended by Amendment No. 2 filed on June 5, 1996, Amendment No. 3 filed on December 19, 2001, Amendment No. 4 filed on December 20, 2005, Amendment No. 5 filed on April 20, 2006, Amendment No. 6 filed on August 8, 2006 and Amendment No. 7 filed on August 10, 2006. The Statement relates to the common shares, par value $.01 per share ("Common Shares"), of IPC Holdings, Ltd., a Bermuda corporation (the "Company"). The principal executive offices of the Company are located at American International Building, 29 Richmond Road, Pembroke HM08, Bermuda. Item 4. Purpose of Transaction. Item 4 is hereby amended to add the following: On August 11, 2006, Citigroup Global Markets, Inc. ("Citigroup") as representative of the several underwriters, in connection with AIG's public offering of the Common Shares it owns, notified AIG of its intention to exercise the over-allotment option to purchase 2 million Common Shares owned by AIG at a price of $27.00 per share. The offering (including the exercise of the over-allotment option in full) is expected to close on August 15, 2006. Giving effect to such sale (including the exercise of the over-allotment option in full), AIG expects that it will no longer have beneficial ownership of any Common Shares, and accordingly it will no longer be subject to the requirement to file a Schedule 13D. Notwithstanding the foregoing, AIG may determine to change its investment intent with respect to the Company at any time in the future. In reaching any conclusion as to its future course of action, AIG may take into consideration various factors, such as the Company's business and prospects, other developments concerning the Company, other business opportunities available to AIG, developments with respect to the business of AIG, and general economic and stock market conditions, including, but not limited to, the market price of the Common Shares and of its own stock. AIG reserves the right, based on all relevant factors, to acquire additional Common Shares in the open market or in privately negotiated transactions, to dispose of all or a portion of its holdings of Common Shares, or to change its intention with respect to any or all of the matters referred to in this Item. -3- SIGNATURE After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this Statement is true, complete and correct.
