 PROSPECTUS SUPPLEMENT SUMMARY
This summary highlights selected information about ACE and this offering. It does not contain all of the information that may be important to you in deciding whether to purchase notes. We encourage you to read the entire prospectus supplement, the accompanying prospectus and the documents that we have filed with the SEC that are incorporated by reference prior to deciding whether to purchase notes.
ACE Limited
ACE Limited is a Bermuda-based holding company incorporated with limited liability under the Cayman Islands Companies Law. ACE is a global property and casualty insurance and reinsurance organization, servicing the insurance needs of commercial and individual customers in more than 140 countries and jurisdictions.
Our long-term business strategy focuses on sustained growth in book value achieved through a combination of underwriting and investment income. We provide value to our clients and shareholders through the utilization of our substantial capital base in the insurance and reinsurance markets. As part of this strategy, we have made a number of acquisitions and have entered into strategic alliances that diversify our operations, both geographically and by product type.
ACE USA, our retail business, operates through several insurance companies using a network of offices throughout the United States and Canada. These operations provide a broad range of property and casualty (P&C) insurance and reinsurance products to a diverse group of commercial and non-commercial enterprises and consumers. These products include general liability, excess liability, property, workers’ compensation, automobile liability, professional lines (D&O and E&O), medical liability, aerospace and accident and health (A&H) coverages as well as claims and risk management products and services. ACE Westchester Specialty focuses on the wholesale distribution of excess, surplus and specialty P&C products, as well as the retail and wholesale distribution of specialty inland marine products. ACE Bermuda provides commercial insurance products to a global client base, covering risks that are generally low in frequency and high in severity.
Our ACE International and ACE Global Markets operations write a variety of insurance products including, but not limited to, property, casualty, professional lines, marine, energy, aviation, political risk, consumer-oriented products and accident and health (principally supplemental accident) products. ACE International operates through a network of indigenous insurance operations in Asia-Pacific, the Far East, Latin America and Europe. ACE Global Markets’ international operations include our insurance operations at Lloyd’s.
Our global reinsurance operations market reinsurance products worldwide under the ACE Tempest Re brand name and provide a broad range of coverages to a diverse array of primary P&C companies. Our global reinsurance operations include our ACE Tempest Re Bermuda subsidiary which is our property catastrophe operation. ACE Tempest Re USA writes all lines of traditional and specialty P&C reinsurance for the North American market, and ACE Tempest Re Europe provides treaty reinsurance of P&C business worldwide, with emphasis on non-U.S. and London market risks. ACE Tempest Re Canada commenced writing business in 2007, offering a full array of P&C reinsurance to the Canadian market.
ACE Tempest Life Re helps clients (ceding companies) manage mortality, morbidity, lapse and/or capital market risks embedded in their books of business. ACE Tempest Life Re operates through two insurance companies: the first a Bermuda-based niche player in the life reinsurance market that provides reinsurance coverage to other life insurance companies, focusing on guarantees included in certain fixed and variable annuity products, and the second a U.S.-based traditional life reinsurance company. ACE International Life provides traditional life insurance and investment and savings products to individuals in several countries, including Thailand, Vietnam, Taiwan, China, Egypt and the United Arab Emirates.

ACE INA Holdings Inc.
ACE INA, the issuer of the notes, is an indirect subsidiary of ACE Limited that was formed in December 1998. ACE INA is a U.S. holding company and has no direct operations. ACE INA’s principal asset is the capital stock of its insurance subsidiaries, which includes the companies that make up ACE USA, ACE International and ACE Westchester Specialty.
Combined Acquisition
On December 14, 2007, ACE agreed to purchase all the outstanding shares of capital stock of Combined Insurance Company of America (“Combined”) from Aon Corporation (“Aon”) for $2.4 billion in cash, subject to a post-closing adjustment relating to Combined’s net worth. Prior to the closing, ACE will assign its right to purchase Combined to ACE INA. Also prior to the closing, Combined expects to declare and pay to Aon a $325 million special dividend of cash and non-cash assets (plus the stock of Sterling Life Insurance Company (“Sterling”), which is currently a subsidiary of Combined and is being sold to a third-party in a separate transaction, or the proceeds from such sale). ACE expects that the purchase price for the transaction will be financed by a combination of available cash, the proceeds of this offering and the proceeds of a new $450 million 5-year term loan agreement (the “New Term Loan Agreement”) for which commitments have been received from a syndicate of banks. The sale of Combined is anticipated to be completed by the end of the second quarter of 2008, subject to the satisfaction of certain conditions.
Following the announcement of ACE’s acquisition of Combined, A.M. Best Company revised Combined’s financial strength rating to under review status positive from negative, Standard & Poor’s Ratings Services placed Combined’s counterparty credit and financial strength ratings on CreditWatch with positive implications, Moody’s Investors Service, Inc. announced it was reviewing Combined’s ratings for upgrade and Fitch Ratings placed Combined’s ratings Rating Watch Positive. A financial strength rating is an opinion with respect to an insurer’s ability to pay under its insurance policies and contracts and is not a recommendation to buy, hold or sell any security issued by an insurer.
Combined, which was founded in 1922 and headquartered in Glenview, IL, is a leading underwriter and distributor of specialty individual accident and supplemental health insurance products that are targeted to middle income consumers in the U.S., Europe, Canada and Asia Pacific. Combined distributes its products through nearly 7,000 full-time career agents and serves more than four million policyholders worldwide.
The acquisition nearly doubles ACE’s A&H business and diversifies ACE’s existing direct-response and brokerage distribution channels through the addition of tied agency distribution. Management of ACE believes that it also provides opportunities for growth, particularly in Latin America and Asia Pacific, as well as financial, expense-related and capital efficiencies.
Recent Financial Results
On February 5, 2008, ACE reported net income for the fourth quarter of 2007 of $572 million compared with net income of $665 million for the same quarter last year. The P&C combined ratio for the fourth quarter of 2007 was 88.1% compared with 88.2% for the fourth quarter of 2006. Net income for the full year 2007 was $2.6 billion compared with net income of $2.3 billion for the prior year. The P&C combined ratio for 2007 was 87.9% compared with 88.1% for 2006.
Gross premiums written during the fourth quarter of 2007 were $4.1 billion, compared with $4.0 billion for the comparable quarter in 2006. Net premiums written during the fourth quarter of 2007 were $2.8 billion compared with $2.9 billion for the same quarter in 2006. Net premiums earned during the fourth quarter of 2007 were $3.0 billion compared with $3.0 billion for the same quarter in 2006. Gross premiums written during the full year 2007 were $17.7 billion, compared with $17.4 billion for the full year 2006. Net premiums written for the full year 2007 were $12.0 billion compared with $12.0 billion for the full year 2006. Net premiums earned during 2007 were $12.3 billion, compared with $11.8 billion for 2006.
At December 31, 2007, ACE had total assets of $72.1 billion, net unpaid losses and loss expenses of $23.6 billion and total shareholders’ equity of $16.7 billion.

(1)	The loss and loss expense ratio is calculated by dividing the losses and loss expenses by net premiums earned excluding life insurance and reinsurance net premiums. Net premiums earned for life insurance and reinsurance were $274 million, $248 million, $226 million, $187 million and $158 million for the years ended December 31, 2006, 2005, 2004, 2003 and 2002, respectively and were $270 million and $196 million for the nine months ending September 30, 2007 and 2006 respectively.	
(2)	The underwriting and administrative expense ratio is calculated by dividing the policy acquisition costs and administrative expenses by net premiums earned excluding life insurance and reinsurance premiums.	
(3)	The combined ratio is the sum of the loss and loss expense ratio and the underwriting and administrative expense ratio.	
(4)	The net loss reserves to capital and surplus ratio is calculated by dividing the sum of the net unpaid losses and loss expenses and net future policy benefits for life and annuity contracts by shareholders’ equity.	
(5)	For purposes of computing the ratios of earnings to fixed charges, earnings consist of net income before income tax expense, excluding interest costs capitalized, plus fixed charges to the extent that these charges are included in the determination of earnings. Fixed charges consist of interest costs, including interest costs capitalized, plus one-third of minimum rental payments under operating leases, which are estimated by management to be the interest factor of these rentals. Earnings for the year ended December 31, 2002 were insufficient to cover fixed charges by $12 million.

 USE OF PROCEEDS
The net proceeds to ACE INA from the sale of the notes will be approximately $297.2 million (after underwriting discounts and our offering expenses). The net proceeds from the sale of the senior notes will be used to pay a portion of the purchase price for the acquisition of Combined. See “Prospectus Supplement Summary—Combined Acquisition.” In the event the acquisition of Combined is not completed, the net proceeds will be used for general corporate purposes, including the repayment or repurchase of indebtedness or other obligations. Pending application of the proceeds of sale of the notes, we intend to invest such proceeds in short-term investments.
 CAPITALIZATION OF ACE
The following table sets forth, at September 30, 2007, our consolidated short-term debt and capitalization on an actual basis and as adjusted to give effect to the sale of the notes and the application of the net proceeds therefrom, together with available cash, to repay indebtedness. You should read this table in conjunction with our consolidated financial statements and the notes thereto which are incorporated by reference.

 DESCRIPTION OF NOTES AND GUARANTEE
We have summarized the provisions of the notes below. The notes constitute “ACE INA senior debt securities” described in the accompanying prospectus. This summary supplements and, to the extent inconsistent with, replaces the description of the general terms and provisions of the ACE INA senior debt securities under the caption “Description of ACE INA Debt Securities and ACE Guarantee” in the accompanying prospectus. In this section, ACE INA refers to ACE INA Holdings Inc., the issuer of the notes, and “ACE” refers to ACE Limited, the guarantor of the notes and, in each case, not to any of their respective subsidiaries.
General
The notes will be issued as a separate series of debt securities under an indenture dated as of August 1, 1999 among ACE INA, as issuer, ACE, as guarantor, and The Bank of New York Trust Company, N.A. (as successor to J.P. Morgan Trust Company, National Association and The First National Bank of Chicago), as trustee. This indenture constitutes the “ACE INA senior indenture” described in the accompanying prospectus.
The ACE INA senior indenture does not limit the amount of notes, debentures or other evidences of indebtedness that ACE INA may issue thereunder and provides that notes, debentures or other evidences of indebtedness may be issued from time to time in one or more series. ACE INA may from time to time, without giving notice to or seeking the consent of the holders of the notes issued in this offering, issue notes having the same ranking and the same interest rate, maturity and other terms as the notes issued in this offering. Any additional notes having such identical terms, together with the notes offered hereby, will constitute a single series of notes under the indenture.
The notes will mature on March 15, 2018 and will bear interest at a rate of 5.80% per year. Interest on the notes will accrue from February 14, 2008 or from the most recent interest payment date to which interest has been paid or duly provided for. In each case, ACE INA:
 
 	•	 	will pay interest on the notes semi-annually in arrears on March 15 and September 15 of each year, beginning September 15, 2008;	
 
 	•	 	will pay interest to the person in whose name a note is registered at the close of business on the March 1 or September 1 respectively preceding each March 15 or September 15 interest payment date;	
 
 	•	 	will compute interest on the basis of a 360-day year consisting of twelve 30-day months;	
 
 	•	 	will make payments on the notes at the offices of the trustee; and	
 
 	•	 	may make payments by wire transfer for notes held in book-entry form or by check mailed to the address of the person entitled to the payment as it appears in the note register.	
If any interest payment date or maturity or redemption date falls on a day that is not a business day, the required payment shall be made on the next business day as if it were made on the date such payment was due and no interest shall accrue on the amount so payable from and after such interest payment date or maturity or redemption date, as the case may be, to such next business day. “Business day” means any day other than a Saturday, Sunday or other day on which banking institutions in The City of New York are authorized or obligated by law, regulation or executive order to close.
ACE INA will issue the notes only in fully registered form, without coupons, in denominations of $2,000 and integral multiples of $1,000 in excess thereof.
Guarantee
ACE will fully and unconditionally guarantee all payments on the notes.
 
S-8

Table of Contents
Ranking
The notes will be senior unsecured obligations of ACE INA and will rank equally in right of payment with all of ACE INA’s other unsecured and unsubordinated indebtedness from time to time outstanding. The guarantee will be a senior unsecured obligation of ACE and will rank equally in right of payment with all of ACE’s other unsecured and unsubordinated indebtedness from time to time outstanding.
The notes will be effectively subordinated to any secured indebtedness of ACE INA or ACE, as the case may be, to the extent of the value of the assets securing such indebtedness. The indenture does not limit the amount of debt that ACE INA, ACE or their respective subsidiaries can incur. However, the indenture does restrict the ability of ACE INA, ACE and their respective subsidiaries to incur secured debt. See “Description of ACE INA Debt Securities and ACE Guarantee—Covenants Applicable to ACE INA Senior Debt Securities” in the accompanying prospectus.
In addition, both ACE and ACE INA conduct their operations through subsidiaries, which generate a substantial portion of their respective operating income and cash flow. As a result, distributions or advances from subsidiaries of ACE INA and ACE are a major source of funds necessary for ACE INA and ACE to meet their respective debt service and other obligations. Contractual provisions, laws or regulations, as well as a subsidiaries’ financial condition and operating requirements, may limit the ability of ACE INA or ACE to obtain cash required to pay ACE INA’s debt service obligations, including payments on the notes, or ACE’s payment obligations under the guarantee. The notes will be structurally subordinated to all obligations of ACE INA’s subsidiaries, including claims with respect to trade payables. The guarantee will be structurally subordinated to all obligations of ACE’s subsidiaries, including claims with respect to trade payables. This means that holders of the notes will have a junior position to the claims of creditors of ACE INA’s subsidiaries on their assets and earnings, and holders of the guarantee will have a junior position to the claims of creditors of ACE’s subsidiaries on their assets and earnings. As of September 30, 2007, ACE INA’s subsidiaries had $304 million of indebtedness outstanding (other than trade payables) and ACE’s subsidiaries had a total of $2.46 billion of indebtedness outstanding (other than trade payables).
Payments of Additional Amounts
We will make all payments on notes without withholding of any present or future taxes or governmental charges of the jurisdiction of ACE’s organization or principal executive offices (each, a “taxing jurisdiction”), unless we are required to do so by applicable law or regulation. If under the laws or regulations of a taxing jurisdiction we are required to withhold amounts, we will, subject to the limitations described in the accompanying prospectus under “Description of ACE INA Debt Securities and ACE Guarantee—Payment of Additional Amounts,” pay to you additional amounts so that every net payment made to you, after the withholding, will be the same amount provided for in the notes and the indenture.
Redemption for Changes in Withholding Taxes
ACE INA will be entitled to redeem the notes, at its option, at any time as a whole but not in part, upon not less than 30 nor more than 60 days’ notice, at 100% of the principal amount thereof, plus accrued and unpaid interest (if any) to the date of redemption (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date), in the event that ACE INA or ACE has become or would become obligated to pay, on the next date on which any amount would be payable with respect to the notes, any additional amounts as a result of:
 
 	•	 	a change in or an amendment to the laws (including any regulations promulgated thereunder) of a taxing jurisdiction, which change or amendment is announced after the date of this prospectus supplement; or	
 
S-9

Table of Contents

 	•	 	any change in or amendment to any official position regarding the application or interpretation of the laws or regulations of a taxing jurisdiction, which change or amendment is announced after the date of this prospectus supplement,	
and, in each case, ACE INA or ACE, as applicable, cannot avoid such obligation by taking reasonable measures available to it.
Before ACE INA publishes or mails any notice of redemption of the notes as described above, it will deliver to the trustee an officers’ certificate to the effect that it cannot avoid its obligation to pay additional amounts by taking reasonable measures available to it and an opinion of independent legal counsel of recognized standing stating that ACE INA or ACE, as applicable, would be obligated to pay additional amounts as a result of a change in tax laws or regulations or the application or interpretation of such laws or regulations.
Optional Redemption
ACE INA may redeem the notes in whole at any time or in part from time to time, at its option, at a redemption price equal to the greater of:
 
 	(1)	100% of the principal amount of the notes to be redeemed; and	
 
 	(2)	the sum of the present values of the remaining scheduled payments of principal and interest (excluding interest accrued to the redemption date) on the notes discounted to the date of redemption on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable Treasury Rate plus 35 basis points,	
plus, in each case, accrued and unpaid interest on the principal amount being redeemed to the redemption date.
“Treasury Rate” means, with respect to any redemption date, (1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15(519)” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the Remaining Life, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue will be determined and the Treasury Rate will be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month) or (2) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per year equal to the semi-annual equivalent yield-to-maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date. The Treasury Rate will be calculated on the third Business Day preceding the redemption date.
“Business Day” means any calendar day that is not a Saturday, Sunday or legal holiday in New York, New York, and on which commercial banks are open for business in New York, New York.
“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the notes to be redeemed.
“Comparable Treasury Price” means (1) the average of four Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.
“Independent Investment Banker” means Banc of America Securities LLC and its successors or, if it is unwilling or unable to select the Comparable Treasury Issue, an independent investment banking institution of national standing appointed by ACE INA.
 
S-10

Table of Contents
“Reference Treasury Dealer” means each of (1) Banc of America Securities LLC and its respective successors; provided, however, that if it shall cease to be a primary U.S. Government securities dealer in New York City, which we refer to as a “Primary Treasury Dealer,” ACE INA will substitute another Primary Treasury Dealer and (2) any three other Primary Treasury Dealers selected by the Independent Investment Banker after consultation with ACE INA.
“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker at 5:00 p.m., New York City time, on the third Business Day preceding such redemption date.
Holders of notes to be redeemed will be sent a redemption notice by first-class mail at least 30 and not more than 60 days before the date fixed for redemption. If fewer than all of the notes are to be redeemed and the notes are global notes held by DTC or its nominee, the particular notes or portions thereof selected for redemption from the outstanding notes not previously redeemed shall be selected by DTC in accordance with its standard procedures. If the notes are not then global notes held by DTC or its nominee, the trustee will select, not more than 60 days and not less than 30 days before the redemption date, the particular notes or portions of the notes for redemption from the outstanding notes not previously called by such method as the trustee deems fair and appropriate. Unless ACE INA defaults in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the notes or portions of the notes called for redemption.
Sinking Fund
The notes will not have the benefit of any sinking fund.
Notices
ACE INA will mail notices and communications to a holder’s address as shown on the note register.
Paying Agents and Transfer Agents
The trustee will be the paying agent and transfer agent for the notes.
The Trustee
The Bank of New York Trust Company, N.A. (as successor to J.P. Morgan Trust Company, National Association and The First National Bank of Chicago), is the trustee under the indenture. The trustee and its affiliates also perform commercial banking services for us for which they receive customary fees.
Book-Entry Delivery and Settlement
Global Notes
We will issue the notes in the form of one or more global notes in definitive, fully registered, book-entry form. The global notes will be deposited with or on behalf of DTC and registered in the name of Cede & Co., as nominee of DTC.
DTC, Clearstream and Euroclear
Beneficial interests in the global notes will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct and indirect participants in DTC. Investors may hold
 
S-11

Table of Contents
interests in the global notes through either DTC (in the United States), Clearstream Banking, societe anonyme, Luxembourg, which we refer to as Clearstream, or Euroclear Bank S.A./ N.V., as operator of the Euroclear System, which we refer to as Euroclear, in Europe, either directly if they are participants in such systems or indirectly through organizations that are participants in such systems. Clearstream and Euroclear will hold interests on behalf of their participants through customers’ securities accounts in Clearstream’s and Euroclear’s names on the books of their U.S. depositaries, which in turn will hold such interests in customers’ securities accounts in the U.S. depositaries’ names on the books of DTC.
DTC has advised us as follows:
 
 	•	 	DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered under Section 17A of the Securities Exchange Act of 1934.	
 
 	•	 	DTC holds securities that its participants deposit with DTC and facilitates the settlement among participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in participants’ accounts, hereby eliminating the need for physical movement of securities certificates.	
 
 	•	 	Direct participants include securities brokers and dealers, banks, trust companies, clearing corporations and other organizations.	
 
 	•	 	DTC is owned by a number of its direct participants and by The New York Stock Exchange, Inc., the American Stock Exchange LLC and the National Association of Securities Dealers, Inc.	
 
 	•	 	Access to the DTC system is also available to others such as securities brokers and dealers, banks and trust companies that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly.	
 
 	•	 	The rules applicable to DTC and its direct and indirect participants are on file with the SEC.	
Clearstream has advised us that it is incorporated under the laws of Luxembourg as a professional depositary. Clearstream holds securities for its customers and facilitates the clearance and settlement of securities transactions between its customers through electronic book-entry changes in accounts of its customers, thereby eliminating the need for physical movement of certificates. Clearstream provides to its customers, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic markets in several countries. As a professional depositary, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Section. Clearstream customers are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and other organizations and may include the underwriters. Indirect access to Clearstream is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Clearstream customer either directly or indirectly.
Euroclear has advised us that it was created in 1968 to hold securities for participants of Euroclear and to clear and settle transactions between Euroclear participants through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash. Euroclear provides various other services, including securities lending and borrowing and interfaces with domestic markets in several countries. Euroclear is operated by Euroclear Bank S.A./ N.V., which we refer to as the Euroclear Operator, under contract with Euroclear Clearance Systems S.C., a Belgian cooperative corporation, which we refer to as the Cooperative. All operations are conducted by the Euroclear Operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator, not the Cooperative. The Cooperative establishes policy for Euroclear on behalf of Euroclear participants. Euroclear participants include banks (including central banks), securities

Table of Contents
brokers and dealers, and other professional financial intermediaries and may include the underwriters. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear participant, either directly or indirectly.
The Euroclear Operator has advised us that it is licensed by the Belgian Banking and Finance Commission to carry out banking activities on a global basis. As a Belgian bank, it is regulated and examined by the Belgian Banking and Finance Commission.
We have provided the descriptions of the operations and procedures of DTC, Clearstream and Euroclear in this prospectus supplement solely as a matter of convenience. These operations and procedures are solely within the control of those organizations and are subject to change by them from time to time. None of us, the underwriters nor the trustee takes any responsibility for these operations or procedures, and you are urged to contact DTC, Clearstream and Euroclear or their participants directly to discuss these matters.
We expect that under procedures established by DTC:
 
 	•	 	upon deposit of the global notes with DTC or its custodian, DTC will credit on its internal system the accounts of direct participants designated by the underwriters with portions of the principal amounts of the global notes; and	
 
 	•	 	ownership of the notes will be shown on, and the transfer of ownership thereof will be effected only through, records maintained by DTC or its nominee, with respect to interests of direct participants, and the records of direct and indirect participants, with respect to interests of persons other than participants.	
The laws of some jurisdictions may require that purchasers of securities take physical delivery of those securities in definitive form. Accordingly, the ability to transfer interests in the notes represented by a global note to those persons may be limited. In addition, because DTC can act only on behalf of its participants, who in turn act on behalf of persons who hold interests through participants, the ability of a person having an interest in notes represented by a global note to pledge or transfer those interests to persons or entities that do not participate in DTC’s system, or otherwise to take actions in respect of such interest, may be affected by the lack of a physical definitive security in respect of such interest.
So long as DTC or its nominee is the registered owner of a global note, DTC or that nominee will be considered the sole owner or holder of the notes represented by that global note for all purposes under the indenture and under the notes. Except as provided below, owners of beneficial interests in a global note will not be entitled to have notes represented by that global note registered in their names, will not receive or be entitled to receive physical delivery of certificated notes and will not be considered the owners or holders thereof under the indenture or under the notes for any purpose, including with respect to the giving of any direction, instruction or approval to the trustee. Accordingly, each holder owning a beneficial interest in a global note must rely on the procedures of DTC and, if that holder is not a direct or indirect participant, on the procedures of the participant through which that holder owns its interest, to exercise any rights of a holder of notes under the indenture or a global note.
Neither we nor the trustee will have any responsibility or liability for any aspect of the records relating to or payments made on account of notes by DTC, Clearstream or Euroclear, or for maintaining, supervising or reviewing any records of those organizations relating to the notes.
Payments on the notes represented by the global notes will be made to DTC or its nominee, as the case may be, as the registered owner thereof. We expect that DTC or its nominee, upon receipt of any payment on the notes represented by a global note, will credit participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the global note as shown in the records of DTC or its nominee. We also expect that payments by participants to owners of beneficial interests in the global note held through such participants
 
S-13

Table of Contents
will be governed by standing instructions and customary practice as is now the case with securities held for the accounts of customers registered in the names of nominees for such customers. The participants will be responsible for those payments.
Distributions on the notes held beneficially through Clearstream will be credited to cash accounts of its customers in accordance with its rules and procedures, to the extent received by the U.S. depositary for Clearstream.
Securities clearance accounts and cash accounts with the Euroclear Operator are governed by the Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of the Euroclear System, and applicable Belgian law (collectively, the “Terms and Conditions”). The Terms and Conditions govern transfers of securities and cash within Euroclear, withdrawals of securities and cash from Euroclear, and receipts of payments with respect to securities in Euroclear. All securities in Euroclear are held on a fungible basis without attribution of specific certificates to specific securities clearance accounts. The Euroclear Operator acts under the Terms and Conditions only on behalf of Euroclear participants and has no record of or relationship with persons holding through Euroclear participants.
Distributions on the notes held beneficially through Euroclear will be credited to the cash accounts of its participants in accordance with the Terms and Conditions, to the extent received by the U.S. depositary for Euroclear.
Clearance and Settlement Procedures
Initial settlement for the notes will be made in immediately available funds. Secondary market trading between DTC participants will occur in the ordinary way in accordance with DTC rules and will be settled in immediately available funds. Secondary market trading between Clearstream customers and/or Euroclear participants will occur in the ordinary way in accordance with the applicable rules and operating procedures of Clearstream and Euroclear, as applicable, and will be settled using the procedures applicable to conventional eurobonds in immediately available funds.
Cross-market transfers between persons holding directly or indirectly through DTC, on the one hand, and directly or indirectly through Clearstream customers or Euroclear participants, on the other, will be effected through DTC in accordance with DTC rules on behalf of the relevant European international clearing system by the U.S. depositary; however, such cross-market transactions will require delivery of instructions to the relevant European international clearing system by the counterparty in such system in accordance with its rules and procedures and within its established deadlines (European time). The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to the U.S. depositary to take action to effect final settlement on its behalf by delivering or receiving the notes in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Clearstream customers and Euroclear participants may not deliver instructions directly to their U.S. depositaries.
Because of time-zone differences, credits of the notes received in Clearstream or Euroclear as a result of a transaction with a DTC participant will be made during subsequent securities settlement processing and dated the business day following the DTC settlement date. Such credits or any transactions in the notes settled during such processing will be reported to the relevant Clearstream customers or Euroclear participants on such business day. Cash received in Clearstream or Euroclear as a result of sales of the notes by or through a Clearstream customer or a Euroclear participant to a DTC participant will be received with value on the DTC settlement date but will be available in the relevant Clearstream or Euroclear cash account only as of the business day following settlement in DTC.
Although DTC, Clearstream and Euroclear have agreed to the foregoing procedures to facilitate transfers of the notes among participants of DTC, Clearstream and Euroclear, they are under no obligation to perform or continue to perform such procedures and such procedures may be changed or discontinued at any time.

Certificated Notes
We will issue certificated notes to each person that DTC identifies as the beneficial owner of the notes of either series represented by a global note upon surrender by DTC of the global note if:
 
 	•	 	DTC notifies us that it is no longer willing or able to act as a depositary for such global note or ceases to be a clearing agency registered under the Securities Exchange Act of 1934, and we have not appointed a successor depositary within 90 days of that notice or becoming aware that DTC is no longer so registered;	
 
 	•	 	an event of default has occurred and is continuing, and DTC requests the issuance of certificated notes; or	
 
 	•	 	we determine not to have the notes of such series represented by a global note.	
Neither we nor the trustee will be liable for any delay by DTC, its nominee or any direct or indirect participant in identifying the beneficial owners of the notes. We and the trustee may conclusively rely on, and will be protected in relying on, instructions from DTC or its nominee for all purposes, including with respect to the registration and delivery, and the respective principal amounts, of the certificated notes to be issued.

 CERTAIN TAX CONSEQUENCES
United States
The following summary describes, in the case of U.S. holders, the material U.S. federal income tax consequences and, in the case of non-U.S. holders, the material U.S. federal income and estate tax consequences of the acquisition, ownership and disposition of the notes but does not purport to be a complete analysis of all the potential tax considerations relating thereto. We have based this summary on the provisions of the Internal Revenue Code of 1986, as amended (the “Code”), the applicable Treasury Regulations promulgated or proposed thereunder, judicial authority and current administrative rulings and practice, all of which are subject to change, possibly on a retroactive basis, or to different interpretation. This summary applies to you only if you are an initial purchaser of the notes who acquires the notes at their original issue price within the meaning of Section 1273 of the Code and holds the notes as capital assets. A capital asset is generally an asset held for investment rather than as inventory or as property used in a trade or business. This summary does not discuss all of the aspects of U.S. federal income and estate taxation that may be relevant to investors in light of their particular investment or other circumstances. This summary also does not discuss the particular tax consequences that might be relevant to you if you are subject to special rules under the U.S. federal income tax laws. Special rules apply, for example, if you are:
 
 	•	 	a bank, thrift, insurance company, regulated investment company, or other financial institution or financial service company;	
 
 	•	 	a broker or dealer in securities or foreign currency;	
 
 	•	 	a non-U.S. holder that has a functional currency other than the U.S. dollar;	
 
 	•	 	a partnership or other flow-through entity;	
 
 	•	 	a subchapter S corporation;	
 
 	•	 	a person subject to alternative minimum tax;	
 
 	•	 	a person who owns the notes as part of a straddle, hedging transaction, integrated transaction, constructive sale transaction or other risk-reduction transaction;	
 
 	•	 	a tax-exempt entity;	
 
 	•	 	a person who has ceased to be a U.S. citizen or to be taxed as a resident alien; or	
 
 	•	 	a person who acquires the notes in connection with his employment or other performance of services.	
In addition, the following summary does not address all possible tax consequences. In particular, except as specifically provided, it does not discuss any estate, gift, generation-skipping, transfer, state, local or foreign tax consequences. ACE INA has not sought a ruling from the Internal Revenue Service, (the “IRS”), with respect to the statements made and the conclusions reached in the following summary, and there can be no assurance that the IRS will agree with such statements and conclusions. For all these reasons, you are urged to consult with your tax advisor about the U.S. federal income tax and other tax consequences of the acquisition, ownership and disposition of the notes.
INVESTORS CONSIDERING THE PURCHASE OF THE NOTES SHOULD CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY CONSEQUENCES ARISING UNDER THE LAWS OF ANY STATE, LOCAL OR FOREIGN TAXING JURISDICTIONS OR UNDER ANY APPLICABLE TAX TREATY.

Table of Contents
U.S. Holders
As explained below, the U.S. federal income tax consequences of acquiring, owning and disposing of the notes depend on whether or not you are a U.S. holder. For purposes of this summary, you are a U.S. holder if you are a beneficial owner of the notes and for U.S. federal income tax purposes are:
 
 	(a)	a citizen or resident of the United States, including an alien individual who is a lawful permanent resident of the United States or who meets the substantial presence residency test under the U.S. federal income tax laws;	
 
 	(b)	a corporation or other entity treated as a corporation for U.S. federal income tax purposes that is created or organized in or under the laws of the United States, any of the fifty states or the District of Columbia;	
 
 	(c)	an estate the income of which is subject to U.S. federal income taxation regardless of its source; or	
 
 	(d)	a trust if a court within the United States is able to exercise primary supervision over the administration of the trust and one or more United States persons have the authority to control all substantial decisions of the trust;	
and if your status as a U.S. holder is not overridden under the provisions of an applicable tax treaty. Notwithstanding clause (d) of the preceding sentence, to the extent provided in Treasury Regulations, certain trusts in existence on August 20, 1996, and treated as United States persons prior to that date that elect to continue to be treated as United States persons also will be U.S. holders.
If a partnership holds the notes, the tax treatment of a partner in the partnership will generally depend upon the status of the partner and upon the activities of the partnership. If you are a partner in such a partnership, you should consult your tax advisor.
Payment of Interest. All of the notes bear interest at a stated fixed rate. You generally must include this stated interest in your gross income as ordinary interest income:
 
 	•	 	when you receive it, if you use the cash method of accounting for U.S. federal income tax purposes; or	
 
 	•	 	when it accrues, if you use the accrual method of accounting for U.S. federal income tax purposes.	
Sale, Exchange or Redemption of Notes. You generally will recognize gain or loss upon the sale, exchange, redemption, retirement or other disposition of the notes measured by the difference between (i) the amount of cash proceeds and the fair market value of any property you receive (except to the extent attributable to accrued interest income not previously included in income, which will generally be taxable as ordinary interest income, or attributable to accrued interest previously included in income, which amount may be received without generating further income), and (ii) your adjusted tax basis in the notes. Your adjusted tax basis in a note generally will equal your cost of the note, less any principal payments previously received by you. Gain or loss on the disposition of a note will generally be capital gain or loss and will be long-term capital gain or loss if you have held the note for more than one year at the time of such disposition. Your ability to offset capital losses against ordinary income is subject to certain limitations. You should consult your tax advisor regarding the treatment of capital gains and losses.
Information Reporting and Backup Withholding Tax. In general, information reporting requirements will apply to payments to certain non-corporate U.S. holders of principal and interest on a note and the proceeds of the sale of a note. If you are a U.S. holder, you may be subject to backup withholding at the applicable statutory rate when you receive interest with respect to the notes, or when you receive proceeds upon the sale, exchange, redemption, retirement or other disposition of the notes. In general, you can avoid this backup withholding by properly executing under penalties of perjury an IRS Form W-9 or substantially similar form that provides:
 
 	•	 	your correct taxpayer identification number; and	
 
S-17

Table of Contents

 	•	 	a certification that (a) you are exempt from backup withholding because you are a corporation or come within another enumerated exempt category, (b) you have not been notified by the IRS that you are subject to backup withholding, or (c) you have been notified by the IRS that you are no longer subject to backup withholding.	
If you do not provide your correct taxpayer identification number on the IRS Form W-9 or substantially similar form, you may be subject to penalties imposed by the IRS.
Backup withholding will not apply, however, with respect to payments made to certain holders, including corporations, certain tax exempt organizations and certain foreign persons, provided their exemptions from backup withholding are properly established.
Amounts withheld are generally not an additional tax and may be refunded or credited against your U.S. federal income tax liability, provided you furnish the required information to the IRS.
ACE INA will report to the U.S. holders of notes and to the IRS the amount of any “reportable payments” for each calendar year and the amount of tax withheld, if any, with respect to such payments.
Non-U.S. Holders
As used in this section, the term, “non-U.S. holder” means any beneficial owner of a note (other than a partnership or other entity treated as a partnership for U.S. federal income tax purposes) that is not a U.S. holder.
Payment of Interest. Generally, subject to the discussion of backup withholding below, if you are a non-U.S. holder, interest income that is not effectively connected with a United States trade or business will not be subject to a U.S. withholding tax under the “portfolio interest exemption” provided that:
 
 	•	 	you do not actually or constructively own 10% or more of the combined voting power of all of ACE INA’s classes of stock entitled to vote;	
 
 	•	 	you are not a controlled foreign corporation related to ACE INA actually or constructively through stock ownership;	
 
 	•	 	you are not a bank which acquired the notes in consideration for an extension of credit made pursuant to a loan agreement entered into in the ordinary course of business; and	
 
 	•	 	either (a) you provide an IRS Form W-8BEN (or a suitable substitute form) signed under penalties of perjury that includes your name and address and certifies as to your non- U.S. holder status, or (b) a securities clearing organization, bank or other financial institution that holds customers’ securities in the ordinary course of its trade or business, provides a statement to us or our agent under penalties of perjury in which it certifies that an IRS Form W-8BEN or W-8IMY (or a suitable substitute form) has been received by it from you or a qualifying intermediary and furnishes us or our agent with a copy of such form.	
Treasury Regulations provide alternative methods for satisfying the certification requirement described in the paragraph above.
Interest on notes not exempted from U.S. withholding tax as described above and not effectively connected with a United States trade or business generally will be subject to U.S. withholding tax at a 30% rate, except where an applicable tax treaty provides for the reduction or elimination of this withholding tax. ACE INA may be required to report annually to the IRS and to each non-U.S. holder the amount of interest paid to, and the tax withheld, if any, with respect to, each non-U.S. holder.
 
S-18

Table of Contents
Except to the extent that an applicable treaty otherwise provides, generally you will be taxed in the same manner as a U.S. holder with respect to interest if the interest income is effectively connected with your conduct of a United States trade or business. If you are a corporate non-U.S. holder, you may also, under certain circumstances, be subject to an additional “branch profits tax” at a 30% rate (or, if applicable, a lower treaty rate). Even though such effectively connected interest is subject to U.S. federal income tax, and may be subject to the branch profits tax, it will not be subject to U.S. withholding tax if you deliver proper documentation (e.g., IRS Form W-8ECI). To claim the benefit of a tax treaty or to claim exemption from U.S. withholding because the income is U.S. trade or business income, the non-U.S. holder must provide a properly executed IRS Form W-8BEN or W-8ECI. Under the Treasury Regulations, a non-U.S. holder may under certain circumstances be required to obtain a U.S. taxpayer identification number and make certain certifications to us. Special procedures are provided in the Treasury Regulations for payments through qualified intermediaries. Prospective investors should consult their tax advisors regarding the effect, if any, of the Treasury Regulations.
Sale, Exchange or Redemption of Notes. If you are a non-U.S. holder of a note, generally you will not be subject to U.S. federal income tax or U.S. withholding tax on any gain realized on the sale, exchange, redemption, retirement or other disposition of the note, unless:
 
 	•	 	the gain is effectively connected with your conduct of a United States trade or business;	
 
 	•	 	you are an individual and are present in the United States for a period or periods aggregating 183 days or more during the taxable year (as determined under the Code) of the disposition and certain other conditions are met; or	
 
 	•	 	you are subject to tax pursuant to the provisions of the Code applicable to certain United States expatriates.	
Death of a Non-U.S. Holder. If you are an individual non-U.S. holder and you hold a note at the time of your death, it will not be includable in your gross estate for U.S. estate tax purposes, provided that you do not at the time of death actually or constructively own 10% or more of the combined voting power of all of our classes of stock entitled to vote, and provided that, at the time of death, payments with respect to such note would not have been effectively connected with your conduct of a trade or business within the United States.
Information Reporting and Backup Withholding Tax. If you are a non-U.S. holder, U.S. information reporting requirements and backup withholding tax generally will not apply to payments of interest on a note if you provide the statement described in “Non-U.S. Holders—Payment of Interest,” provided that the payor does not have actual knowledge that you are a United States person. However, income allocable to non-U.S. holders generally will be subject to annual tax reporting on IRS Form 1042-S.
Information reporting will not apply to any payment of the proceeds of the sale of a note effected outside the United States by a foreign office of a “broker” (as defined in applicable Treasury Regulations), unless such broker:
 
 	(i)	is a United States person;	
 
 	(ii)	is a foreign person that derives 50% or more of its gross income for certain periods from the conduct of a trade or business in the United States;	
 
 	(iii)	is a controlled foreign corporation for U.S. federal income tax purposes; or	
 
 	(iv)	is a foreign partnership, if at any time during its tax year, one or more of its partners are United States persons (as defined in the applicable Treasury Regulations) who in the aggregate hold more than 50% of the income or capital interests in the partnership or if, at any time during its tax year, such foreign partnership is engaged in a United States trade or business.	
Payment of the proceeds of any such sale effected outside the United States by a foreign office of any broker that is described in (i), (ii), (iii) or (iv) of the preceding sentence will be subject to information reporting and

backup withholding requirements unless such broker has documentary evidence in its records that you are a non-U.S. holder and certain other conditions are met, or you otherwise establish an exemption. Payment of the proceeds of any such sale to or through the United States office of a broker is subject to information reporting and backup withholding requirements, unless you provide the statement described in “Non-U.S. Holders—Payment of Interest” or otherwise establish an exemption.
Cayman Islands Taxation

 UNDERWRITING
We are offering the notes described in this prospectus supplement through a number of underwriters. Banc of America Securities LLC is the representative of the underwriters. We have entered into a firm commitment underwriting agreement with the underwriters. Subject to the terms and conditions of the underwriting agreement, we have agreed to sell to the underwriters, and each underwriter has severally agreed to purchase, the aggregate principal amount of notes listed next to its name in the following table:

Underwriter	  	Principal Amount
of Notes	
Banc of America Securities LLC	  	 	120,000,000	
Citigroup Global Markets Inc.	  	 	36,000,000	
Deutsche Bank Securities Inc.	  	 	36,000,000	
J.P. Morgan Securities Inc.	  	 	36,000,000	
Mitsubishi UFJ Securities International plc	  	 	36,000,000	
Wachovia Capital Markets, LLC	  	 	36,000,000	
	  	 	 	
Total	  	$	300,000,000	
	  	 	 	
The underwriting agreement is subject to a number of terms and conditions and provides that the underwriters must buy all of the notes if they buy any of them. The underwriters will sell the notes to the public when and if the underwriters buy the notes from us.
The underwriters have advised us that they propose initially to offer the notes to the public for cash at the public offering price set forth on the cover of this prospectus supplement, and to certain dealers at such price less a concession not in excess of .400% of the principal amount of the notes. The underwriters may allow, and such dealers may reallow, a concession not in excess of .250% of the principal amount of the notes to certain other dealers. After the initial public offering of the notes, the public offering price and other selling terms may be changed.
We estimate that our share of the total expenses of the offering, excluding underwriting discounts, will be approximately $600,000.
We have agreed to indemnify the underwriters against, or contribute to payments that the underwriters may be required to make in respect of, certain liabilities, including liabilities under the Securities Act of 1933.
The notes are a new issue of securities with no established trading market. The notes will not be listed on any securities exchange or on any automated dealer quotation system. The underwriters may make a market in the notes after completion of the offering, but will not be obligated to do so and may discontinue any market-making activities at any time without notice. No assurance can be given as to the liquidity of the trading market for the notes or that an active public market for the notes will develop. If an active public market for the notes does not develop, the market price and liquidity of the notes may be adversely affected.
In connection with the offering of the notes, the representatives may engage in transactions that stabilize, maintain or otherwise affect the price of the notes. Specifically, the representatives may overallot in connection with the offering, creating a short position. In addition, the representatives may bid for, and purchase, the notes in the open market to cover short positions or to stabilize the price of the notes. Any of these activities may stabilize or maintain the market price of the notes above independent market levels, but no representation is made hereby of the magnitude of any effect that the transactions described above may have on the market price of the notes. The representatives will not be required to engage in these activities, and may engage in these activities, and may end any of these activities, at any time without notice.
The representatives also may impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representatives have repurchased notes sold by or for the account of such underwriter in stabilizing or short covering transactions.

Table of Contents
The underwriters and certain of their affiliates have provided from time to time, and may provide in the future, investment and commercial banking and financial advisory services to us and our affiliates in the ordinary course of business, for which they have received and may continue to receive customary fees and commissions.
The underwriters or their affiliates are also lenders under the New Term Loan Agreement.
Mitsubishi UFJ Securities International plc is not a U.S. registered broker-dealer and, therefore, to the extent that it intends to effect any sales of the notes in the United States, it will do so through one or more U.S. registered broker-dealers as permitted by the regulations of the Financial Industry Regulatory Authority, Inc.
It is expected that delivery of the notes will be made on or about the date specified on the cover page of this prospectus supplement, which will be the fifth business day following the date of this prospectus supplement. Under Rule 15c6-1 of the Securities and Exchange Commission (SEC) under the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, the purchasers who wish to trade notes on the date of this prospectus supplement or the next succeeding business day will be required to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement. Purchasers of notes who wish to trade notes on the date of this prospectus supplement or the next succeeding business day should consult their own advisors.
Selling Restrictions
Each of the underwriters, severally and not jointly, has represented and agreed that it has not and will not offer, sell, or deliver any of the notes, directly or indirectly, or distribute this prospectus supplement or the attached prospectus or any other offering material relating to the notes, in any jurisdiction except under circumstances that will result in compliance with applicable laws and regulations and that will not impose any obligations on us except as set forth in the underwriting agreement.

 	(c)	in any other circumstances which do not require us to publish a prospectus pursuant to Article 3 of the Prospectus Directive.	
For purposes of this provision, the expression an “offer of notes to the public” in relation to any notes in any Relevant Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the notes to be offered so as to enable you to decide to purchase or subscribe for the notes, as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State, and the expression “Prospectus Directive” means Directive 2003/71/EC and includes any relevant implementing measure in each Relevant Member State.

ACE Capital Trust III is a statutory trust created under Delaware law pursuant to (1) a trust agreement executed by ACE, as original sponsor of the ACE Trust, and the ACE trustees for the ACE Capital Trust III and (2) the filing of a certificate of trust with the Delaware Secretary of State on May 19, 1999. On August 5, 1999, ACE assigned its rights and obligations as sponsor of ACE Capital Trust III to ACE INA. ACE Capital Trust IV is a statutory trust created under Delaware law pursuant to (1) a trust agreement executed by ACE INA, as sponsor of the ACE Capital Trust IV, and the ACE trustees for the ACE Trust and (2) the filing of a certificate of trust with the Delaware Secretary of State on May 14, 2002. Each trust agreement will be amended and restated in its entirety substantially in the form filed as an exhibit to the registration statement of which this prospectus forms a part. Each restated trust agreement will be qualified as an indenture under the Trust Indenture Act of 1939. Each ACE Trust exists for the exclusive purposes of:

However, if an event of default under the restated trust agreement resulting from an event of default under the ACE INA subordinated debt securities held by the ACE Trust has occurred and is continuing, the rights of the holder of the common securities to payment in respect of distributions and payments upon liquidation, redemption and otherwise will be subordinated to the rights of the holders of the preferred securities. Unless otherwise disclosed in the applicable prospectus supplement, ACE INA will, directly or indirectly, acquire common securities in an aggregate liquidation amount equal to at least 3% of the total capital of each ACE Trust. Each of the ACE Trusts is a legally separate entity, and the assets of one are not available to satisfy the obligations of the other.
 
The following is true for each ACE Trust unless otherwise disclosed in the related prospectus supplement:
 
 	•	 	each ACE Trust has a term of approximately 55 years but may dissolve earlier;

 	•	 	one ACE trustee of each ACE Trust will be a financial institution that is not affiliated with ACE INA and has a minimum amount of combined capital and surplus of not less than $50,000,000, and is referred to as the property trustee. The property trustee shall act as both the property trustee and as indenture trustee for the purposes of compliance with the provisions of the Trust Indenture Act;	
 
 	•	 	one ACE trustee of each ACE Trust, which may be the property trustee if it otherwise meets the requirements of applicable law, will have its principal place of business or reside in the State of Delaware and is referred to as the Delaware trustee;	
 
 	•	 	ACE will pay all fees and expenses related to each ACE Trust and the offering of the preferred securities and common securities.	
 
The office of the Delaware trustee for each ACE Trust in the State of Delaware is located at c/o Chase Bank USA, National Association c/o JPMorgan Chase Bank, N.A., 500 Stanton Christiana Road, OPS4/3rd Floor, Newark, Delaware 19713.

 DESCRIPTION OF ACE CAPITAL STOCK
 
The following is a summary of the material provisions of ACE’s memorandum of association and articles of association. You should refer to ACE’s memorandum and articles for complete information regarding their provisions, copies of which are incorporated by reference as exhibits to the registration statement of which this prospectus forms a part.
 
ACE’s authorized share capital consists of two classes of shares:
 
 	•	 	500,000,000 ordinary shares, par value $0.041666667 per share, of which 288,672,450 ordinary shares were issued and outstanding as of September 30, 2005; and	
 
 	•	 	20,000,000 other shares, 2,300,000 shares of which were issued and outstanding as of September 30, 2005, as 7.80% cumulative redeemable preferred shares, series C.	
 
Ordinary Shares
 
Our ordinary shares are listed on the New York Stock Exchange under the symbol “ACE.” Our ordinary shares currently issued and outstanding are fully paid and nonassessable, which means that our ordinary shares are paid for in full at the time they are issued, and, once our ordinary shares are paid for in full, there is no further liability for further assessment or taxation. Any of our ordinary shares offered by a prospectus supplement will also be fully paid and nonassessable once they are issued to the purchaser in exchange for the full purchase price.
 
There are no provisions of Cayman Islands law or our memorandum or articles which impose any limitation on the rights of our shareholders to hold or vote ordinary shares by reason of their not being residents of the Cayman Islands.
 
Dividend Rights
 
After all dividends on our preferred shares have been paid or declared and set apart for payment, holders of our ordinary shares are entitled to receive dividends as may be declared from time to time by our board of directors in its discretion, out of funds legally available for the payment of dividends.
 
Liquidation
 
In the event of our dissolution, liquidation or winding, whether voluntary or involuntary, we will first pay or set aside for payment to the holders of any outstanding shares ranking senior to our ordinary shares, the full amounts to which they are entitled. After these payments have been paid or set aside, the holder of our then outstanding ordinary shares, will be entitled to receive, pro rata , according to the number of ordinary shares registered in their names, any of our remaining assets which remain available for distribution. However, if, at the time of our dissolution, liquidation or winding up, you have any outstanding debts, liabilities or engagements to or with us, whether presently payable or not, either alone or jointly with any other person, whether a shareholder or not, including, without limitation, any liability associated with the unpaid purchase price of our ordinary shares, the liquidator appointed to oversee our liquidation will deduct the aggregate amount of these debts, liabilities and engagements from the amount payable in respect of your ordinary shares. The liquidator will then apply this amount to any of your debts, liabilities or engagements to or with ACE, whether presently payable or not. The liquidator may distribute to you, in kind, the remaining assets of ACE or may sell, transfer or otherwise dispose of all or any part of our remaining assets to any other corporation, trust or entity and receive payment for our remaining assets in cash, shares or obligations of the other corporation, trust or entity or any combination of these. The liquidator may also sell all or part of the consideration received for the sale of our remaining assets and distribute this consideration or any balance or proceeds of this consideration to you.

Voting Rights
 
Our articles provide that the quorum required for a general meeting of shareholders is not less than six shareholders present in person or by proxy holding at least 50% of the issued and outstanding shares entitled to vote at the meeting, and a quorum for considering a special resolution is 66  2 / 3 % of the issued and outstanding shares entitled to vote at the meeting. Generally, we may, from time to time by special resolution:
 
 	•	 	alter or amend our memorandum or articles;	
 
 	•	 	voluntarily liquidate, dissolve or wind-up our affairs;	
 
 	•	 	increase our share capital;	
 
 	•	 	consolidate and divide all or any of our share capital;	
 
 	•	 	subdivide the whole or any part of our share capital;	
 
 	•	 	reduce our share capital, any capital redemption reserve fund or any share premium account; or	
 
 	•	 	change our name or alter our objects.	
 
Each holder of our ordinary shares is entitled to one vote per share on all matters submitted to a vote of shareholders at any meeting, subject to the 10% voting limitation described below. All matters, including the election of directors, voted upon at any duly held shareholders’ meeting will be carried by a majority of the votes cast at the meeting by shareholders represented in person or by proxy. However, the following actions, among others, require the approval of at least 66  2 / 3 % of the outstanding voting shares, voting together as a single class:
 
 	•	 	the approval of a merger, consolidation or amalgamation;	
 
 	•	 	the sale, lease or exchange of all or substantially all of our assets, in addition to any regulatory or court approvals, and	
 
 	•	 	the amendment of specific provisions of our articles.	
 
In addition, at least 66  2 / 3 % of the votes cast by shareholders represented in person or by proxy at a duly convened meeting is required to approve a special resolution.
 
Our articles provide that, generally, extraordinary general meetings of ACE’s shareholders may be called only by directors or at the request in writing of shareholders owning at least 25% of the outstanding shares generally entitled to vote.
 
Each ordinary share has one vote. However, if and so long as, the controlled shares of any person constitute 10% or more of the issued ordinary shares, the voting rights with respect to these controlled shares will be limited, in the aggregate, to a voting power of approximately 10%, pursuant to a formula specified in our articles. The term controlled shares generally means all shares of ACE directly, indirectly, constructively or beneficially owned by any person, including any shares owned by a group of persons.
 
Our ordinary shares have noncumulative voting rights, which means that the holders of a majority of our ordinary shares may elect all of our directors, and, in this event, the holders of the remaining shares will not be able to elect any directors. Our board is presently divided into three classes, two of which have five directors and one of which has six directors, which we refer to as a classified board. At present, each class is elected for a three-year term, with the result that shareholders will not vote for the election of a majority of directors in any single year. Directors may be removed without cause only by the affirmative vote of the holders of at least 66  2 / 3 % of the outstanding shares generally entitled to vote, voting together as a single class, cast at a meeting of

Table of Contents
shareholders. Directors may be removed with cause by the affirmative vote of the holders of a majority of the votes cast at a meeting of shareholders.
 
Our classified board could prevent a party who acquires control of a majority of the outstanding voting power from obtaining control of our board until the second annual shareholders meeting following the date the acquiror obtains the controlling share interest. This could have the effect of discouraging a potential acquiror from making a tender offer or otherwise attempting to obtain control of ACE and could increase the likelihood that incumbent directors will retain their positions.
 
Preemptive Rights
 
No holder of ordinary shares, solely by reason of holding our ordinary shares, has or will have any preemptive right to subscribe to any additional issue of shares of any class or series nor to any security convertible into ordinary shares.
 
Other Classes or Series of Shares
 
Our articles generally authorize the directors to create and issue one or more other classes or series of shares and to determine the rights and preferences of each class or series. Among other rights, for each class or series, the directors may determine:
 
 	•	 	the number of shares and the designation of the class or series;	
 
 	•	 	the voting powers, full or limited, if any, of the shares;	
 
 	•	 	the dividend rights of the shares, whether dividends will be cumulative and, if so, from which date or dates and the relative rights or priority, if any, of payment of dividends on shares, as well as any limitations, restrictions or conditions on the payment of dividends;	
 
 	•	 	the relative amounts, and the relative rights or priority, if any, of payment in respect of shares, which you will be entitled to receive upon any liquidation, dissolution or winding up of ACE;	
 
 	•	 	the terms and conditions, including the price or prices, which may vary under different conditions and at different redemption dates, if any, upon which all or any part of the shares may be redeemed, as well as any limitations, restrictions or conditions on redemption of the shares;	
 
 	•	 	the terms, if any, of any purchase, retirement or sinking fund to be provided for the shares;	
 
 	•	 	the terms, if any, upon which the shares will be convertible into or exchangeable for shares of any other class, classes or series, or other securities, whether or not issued by ACE;	
 
 	•	 	the restrictions, limitations and conditions, if any, upon the issuance of indebtedness of ACE so long as any shares are outstanding; and	
 
 	•	 	any other preferences and relative, participating, optional or other rights and limitations not inconsistent with applicable law or our articles.	
 
Preferred Shares
 
Our articles provide that the directors may, from time to time, create and issue other classes or series of preferred shares setting forth the rights and preferences of each class or series in a certificate of designation, which certificate of designations we would incorporate by reference into this prospectus. Our preferred shares will be fully paid and nonassessable once they are issued in exchange for payment of their full purchase price. The particular rights and preferences of the preferred shares offered by any prospectus supplement and the extent, if any, to which the general provisions described below may apply to the offered preferred shares, will be described in the applicable prospectus supplement.

Table of Contents
The following is a summary of the material terms of our preferred shares and you should refer to our memorandum, articles and the applicable certificate of designations for complete information regarding the terms of any class or series of preferred shares described in a prospectus supplement.
 
The applicable prospectus supplement will specify the terms of the class or series of preferred shares, including:
 
 	•	 	the number of shares to be issued and sold and the distinctive designation of the class or series;	
 
 	•	 	the voting powers, full or limited, if any;	
 
 	•	 	the dividend rights, whether dividends will be cumulative and, if so, from which date or dates and the relative rights or priority, if any, of payment of dividends, as well as any limitations, restrictions or conditions on the payment of dividends;	
 
 	•	 	the relative amounts, and the relative rights or priority, if any, of payment in respect of preferred shares, which the holders of the preferred shares will be entitled to receive upon any liquidation, dissolution or winding up of ACE;	
 
 	•	 	the terms and conditions, including the price or prices, which may vary under different conditions and at different redemption dates, if any, upon which all or any part of the preferred shares may be redeemed, as well as any limitations, restrictions or conditions on redemption;	
 
 	•	 	the terms, if any, of any purchase, retirement or sinking fund;	
 
 	•	 	the terms, if any, upon which the preferred shares will be convertible into or exchangeable for shares of any other class, classes or series, or other securities, whether or not issued by ACE;	
 
 	•	 	the restrictions, limitations and conditions, if any, upon the issuance of indebtedness of ACE so long as any preferred shares are outstanding; and	
 
 	•	 	any other preferences and relative, participating, optional or other rights and limitations not inconsistent with applicable law, our memorandum or articles.	
 
Dividends
 
You, as a holders of preferred shares, will be entitled to receive dividends at the rate set by the board, payable on specified dates each year for the respective dividend periods ending on those dates, when and as declared by the board. Dividends will accrue on each preferred share from the first day of the dividend period in which the share is issued or from any other date as the board may fix for this purpose. All dividends on preferred shares will be cumulative, which means that if we do not pay, or declare and set apart funds for payment of, the dividend, or any part of the dividend, on the issued and outstanding preferred shares for any dividend period, we must later pay in full, or declare and set apart for payment, the deficiency in the dividend on the preferred shares, without interest, before we may pay, or declare and set apart for payment, any dividend on the ordinary shares. You will not be entitled to participate in any other or additional earnings or profits of ACE, except for premiums, if any, which may be payable in case of redemption or liquidation, dissolution or winding up of ACE.
 
At any time when any accrued dividends for any prior dividend period are delinquent, we will expressly declare any dividend paid upon the preferred shares to be in whole or partial payment of the accrued dividends beginning with the earliest dividend period for which dividends are then wholly or partly delinquent. This express designation of whole or partial payments will be communicated to each shareholder to whom payment is made.
 
We will not pay dividends upon any shares of any class or series of preferred shares for a current dividend period unless we have paid, or declared and set apart for payment, all dividends required to be paid to the holders

Table of Contents
of each other class or series of preferred shares for all past dividend periods of the other class or series. If we pay any dividends on any of the preferred shares with respect to any past dividend period at any time when we are paying, or declaring and setting apart for payment, less than the total dividends then accumulated and payable for all past dividend periods on all of the preferred shares then outstanding, then we will pay the dividends on each class or series of preferred shares in the proportions that the dividends then accumulated and payable on each class or series for all past dividend periods bear to the total dividends then accumulated and payable for all past dividend periods on all outstanding preferred shares.
 
Liquidation, Dissolution or Winding Up
 
If we liquidate, dissolve or wind up our business, whether voluntarily or involuntarily, we will pay you a sum out of our assets equal to the liquidation preference for the class or series of preferred shares you own plus all accrued but unpaid dividends on your preferred shares, whether or not earned or declared. We will make these payments to you before any of our assets will be paid or distributed to holders of our ordinary shares. If our assets are insufficient to pay the full amounts to which you and the holders of all of the classes or series of our preferred shares then outstanding may be entitled, you will share ratably in our assets in proportion to the amounts which would be payable with respect to each class or series if all amounts payable on each class or series of preferred shares were paid in full. The consolidation or merger of ACE with or into any other corporation, or a sale of all or any part of its assets, will not be deemed a liquidation, dissolution or winding up of ACE within the meaning of this paragraph.
 
Redemption
 
Except as otherwise set forth in the applicable prospectus supplement, the following redemption provisions will apply to each class or series of preferred shares.
 
Prior to redeeming any preferred shares, we will deposit adequate funds for the redemption in trust for your account with a bank or trust company that has an office in the United States, and that has, or is an affiliate of a bank or trust company that has, capital and surplus of at least $50,000,000. After we deposit these funds in trust, or have stated our intent to deposit these funds in a redemption notice, and you are given the name and address of the bank or trust company, then, from and after the mailing of the notice and the making of the deposit, your shares will no longer be deemed to be outstanding for any purpose whatsoever and your rights in or with respect to ACE pursuant to these preferred shares will cease and terminate, except for your rights:
 
 	•	 	to transfer your shares prior to the date fixed for redemption,	
 
 	•	 	to receive the redemption price of your shares, including accrued but unpaid dividends to the date fixed for redemption, without interest, upon surrender of the certificate or certificates representing the shares to be redeemed, and	
 
 	•	 	to exercise privileges of conversion, if any, not previously expired on or before the close of business on the fifth day preceding the date fixed for redemption.	
 
Six years after the redemption date, any moneys we deposit in trust which remain unclaimed and not converted will be paid to us upon our request, after which repayment you can no longer look to the bank or trust company for the payment of the redemption price but must look only to us for the payment of any lawful claim for these moneys. In addition, after this six-year period, your right to receive this payment may be forfeited as provided under Cayman Islands law. Any portion of the moneys we deposit in respect of your preferred shares called for redemption that are converted into ordinary shares will be repaid to us upon our request.
 
10

Table of Contents
In case of the redemption of only a part of a class or series of preferred shares, we will designate by lot, in a manner as determined by the board, the shares to be redeemed or will effect the redemption pro rata .
 
Conversion Rights
 
Except as otherwise provided in the applicable prospectus supplement, the following conversion provisions will apply to each class or series of preferred shares that is convertible into ordinary shares.
 
All ordinary shares issued upon conversion will be fully paid and nonassessable and will be free of all taxes, liens and charges with respect to their issue, except taxes, if any, payable by reason of issuance of the ordinary shares in a name other than your name.
 
The number of ordinary shares issuable upon conversion of a particular class or series of preferred shares will be the quotient obtained by dividing the aggregate conversion value of the shares of the class or series surrendered for conversion by the conversion price per share of ordinary shares then in effect for the class or series. We will not be required, however, upon any conversion to issue any fractional share of ordinary shares, but instead we will pay you a sum in cash equal to the value of the fractional share based on the last reported sale price per ordinary share on the NYSE at the date of determination. Preferred shares will be deemed to have been converted as of the close of business on the date of receipt at the office of the transfer agent of the certificates, duly endorsed, together with written notice of your election to convert the shares.
 
The basic conversion price per ordinary share for a class or series of preferred shares, as fixed by the board, will be subject to adjustment from time to time as follows.
 
If we:
 
 	•	 	pay a dividend or make a distribution to all holders of outstanding ordinary shares as a class in ordinary shares,	
 
 	•	 	subdivide or split the outstanding ordinary shares into a larger number of shares or	
 
 	•	 	combine the outstanding ordinary shares into a smaller number of shares,	
 
then we will retroactively adjust your basic conversion price so that your convertible preferred shares will be entitled to receive, upon conversion, the number of ordinary shares which you would have owned and been entitled to receive after the happening of any of the events described above had your shares been converted immediately prior to the happening of that event.
 
If we issue to all holders of ordinary shares as a class any rights or warrants enabling them to subscribe for or purchase ordinary shares at a price per share less than the current market price per ordinary share at the record date for determination of shareholders entitled to receive these rights or warrants, then we will retroactively adjust your basic conversion price by multiplying your basic conversion price by a fraction. The fraction’s numerator will be the sum of the number of ordinary shares outstanding at the record date plus the number of ordinary shares which the aggregate exercise price, before deduction of underwriting discounts or commissions and our other expenses in connection with the issue, of the total number of shares offered for subscription or purchase would purchase at the current market price per share. The fraction’s denominator will be the sum of the number of ordinary shares outstanding at the record date plus the number of additional ordinary shares offered for subscription or purchase.
 
If we distribute to all holders of ordinary shares as a class evidences of indebtedness or assets, other than cash dividends, then we will retroactively adjust your basic conversion price by multiplying your basic conversion price by a fraction. The fraction’s numerator will be the difference between the current market price per ordinary share at the record date for determination of shareholders entitled to receive the distribution and the
 
11

Table of Contents
fair value, as determined by the board, of the portion of the evidences of indebtedness or assets, other than cash dividends, so distributed applicable to one ordinary share. The fraction’s denominator will be the current market price per ordinary share, which will be deemed to be the average of the high and low sales prices of the ordinary shares as reported in the New York Stock Exchange—Composite Transactions, or other principal market quotation as may then be applicable to the ordinary shares, for each of the 30 consecutive trading days commencing 45 trading days before that date.
 
Any adjustments described above will become effective retroactively immediately after the applicable record date, or, in the case of a subdivision, split or combination, immediately after the effective date, and these adjustments will be made successively whenever any event described occurs.
 
We will not adjust the basic conversion price if the amount of the adjustment would be less than 50 cents. However, any adjustments, which, by reason of the preceding sentence, we do not make, will be carried forward and taken into account in any subsequent adjustment. In addition, we will make any adjustment required for purposes of making the computations described above not later than the earlier of three years after the effective date describe above for the adjustment and the date as of which the adjustment would result in an increase or decrease of at least 3% in the aggregate number of ordinary shares issued and outstanding on the first date on which an event occurred which required the making of the computation. We will make all calculations to the nearest cent or to the nearest 1/100th of a share, as the case may be.
 
In the case of any capital reorganization or reclassification of ordinary shares, or if we consolidate with or merge into, or sell or dispose of all or substantially all of our property and assets to, any other corporation, we will make proper provisions as part of the terms of the capital reorganization, reclassification, consolidation, merger or sale that any preferred shares at the time outstanding will be convertible into the number of shares of stock or other securities or property to which a holder of the number of ordinary shares deliverable upon conversion of the preferred shares would have been entitled upon the capital reorganization, reclassification, consolidation or merger.
 
We will not make any dividend adjustment with respect to any preferred shares or ordinary shares in connection with any conversion.
 
Whenever we issue additional ordinary shares requiring a change in the conversion price as described above, and whenever any other event occurs which results in a change in your existing conversion rights, we will file with our transfer agent or agents a statement signed by our Chairman, President and Chief Executive Officer, or by any of our Executive Officers, specifically describing the issue of additional ordinary shares or the other event, including, in the case of a capital reorganization, reclassification, consolidation or merger, the terms of the capital reorganization, reclassification, consolidation or merger. The statement will also contain the actual conversion prices or basis of conversion as changed by the issue or event and the change, if any, in the securities issuable upon conversion. Whenever we issue any rights or warrants to all holders of our ordinary shares as a class enabling them to subscribe for or purchase ordinary shares, we will also file in like manner a statement describing the same and the consideration we will receive. These statements will be open to your inspection.
 
We will at all times authorize, and will at all times reserve and set aside, a sufficient number of ordinary shares for the conversion of all shares of all then outstanding classes or series of preferred shares which are then convertible into ordinary shares.
 
Reissuance of Shares
 
If we retire any preferred shares by purchase or redemption, through conversion, or through the operation of any sinking fund or redemption or purchase account, these shares will have the status of authorized but
 
12

Table of Contents
unissued preferred shares. We may reissue these shares as part of the same class or series or may reclassify and reissue them in the same manner as any other authorized and unissued preferred shares.
 
Voting Rights
 
Except as set forth below, generally, you, as a holder of preferred shares, will have no voting rights.
 
Whenever dividends payable on your shares are in arrears in an aggregate amount equivalent to six full quarterly dividends on all of the preferred shares, you will have the exclusive and special right, voting separately as a class, to elect two of our directors, and we will increase the number of directors constituting the board to the extent necessary to effectuate this right. Whenever this right has vested, it may be exercised initially either at an extraordinary meeting of the holders of the preferred shares or at any annual meeting of shareholders and, after its initial exercise, at annual meetings of shareholders. This special voting right will continue until all dividends accumulated on the preferred shares have been paid in full, at which time this right will terminate, subject to revesting in the event of each and every subsequent default in payment of dividends in an aggregate amount equivalent to six full quarterly dividends.
 
At any time when this special voting right has vested, we will, upon the written request of the holders of record of at least 10% of the preferred shares then outstanding addressed to the Secretary of ACE, call an extraordinary meeting of the holders of the preferred shares for the purpose of electing directors. This extraordinary meeting will be held at the earliest practicable date in a place we designate or, if there be no designation, at our principal offices in Hamilton, Bermuda. If we do not call this meeting within 20 days after the Secretary of ACE has been personally served with the proper request, or within 30 days after mailing the same within the United States by registered or certified mail addressed to the Secretary of ACE at our principal office, then the holders of record of at least 10% of the preferred shares then outstanding may designate in writing one of their number to call the meeting at our expense, and this meeting may be called by this designated person upon the notice required for annual meetings of shareholders and will be held in Hamilton, Bermuda. This designated person will have access to our stock books for the purpose of causing meetings of shareholders to be called. However, we do not have to, and will not, call an extraordinary meeting during the period within 90 days immediately preceding the date fixed for the next annual meeting of shareholders.
 
At any annual or extraordinary meeting at which the holders of the preferred shares have this special voting right, the presence, in person or by proxy, of the holders of 33  1 / 3 % of the preferred shares will be required to constitute a quorum for the election of any director. At any meeting or adjournment of the meeting, the absence of a quorum will not prevent the election of directors other than those to be elected pursuant to this special voting right, and the absence of a quorum for the election of other directors will not prevent the election of the directors to be elected pursuant to this special voting right. In addition, in the absence of either or both types of quorum, a majority of the holders present in person or by proxy of any class or series of stock for which a quorum is lacking may adjourn the meeting for the election of directors which they are entitled to elect, from time to time, until a quorum shall be present, without notice other than announcement at the meeting.
 
During any period during which the holders of preferred shares have the special voting right, only a vote of a majority, even if that be only a single director, of the remaining directors previously elected by the holders of the class or series of stock which elected the directors whose offices have become vacant may fill any board vacancy. During this period, the directors elected pursuant to the special voting right shall continue in office until the next succeeding annual meeting or until their successors, if any, are elected by these holders and qualify or, unless required by applicable law to continue in office for a longer period, until termination of the special voting right, if earlier. If and to the extent permitted by applicable law, immediately upon any termination of the special voting right, the term of office of the directors then in office elected pursuant to the special voting right will terminate.

Table of Contents
Whether or not our business is being wound up, your rights may only be varied with either the written consent of the holders of three-fourths of the issued shares of your class or series of preferred shares or the sanction of a special resolution approved by at least 66  2 / 3 % of the votes cast by the holders of the shares of your class or series of preferred shares at a duly convened meeting where at least one-third of the issued shares of that class or series are represented, either in person or by proxy. Your rights will not be deemed to be varied by the creation or issue of any shares or any securities convertible into or evidencing the right to purchase shares ranking prior to or equally with your class or series of preferred shares with respect to the payment of dividends or of assets upon liquidation, dissolution or winding up. You are not entitled to vote on any amalgamation, consolidation, merger or statutory share exchange, except to the extent that this type of a transaction would vary your rights, in which case any variation is subject to the approval process described above. You are not entitled to vote on any sale of all or substantially all of our assets.
 
On any item on which the you are entitled to vote, you will be entitled to one vote for each preferred share held.
 
Restrictions in Event of Default in Dividends on Preferred Shares
 
If, at any time, we have failed to pay dividends or amounts payable with respect to any obligations to retire preferred shares in full, after that time and until dividends or these amounts, including all accrued and unpaid dividends for all past quarterly dividend periods on the preferred shares outstanding, shall have been declared and set apart in trust for payment or paid, we may not:
 
 	•	 	redeem less than all of the outstanding preferred shares without the affirmative vote or consent of the holders of at least 66  2 / 3 % of the outstanding preferred shares given in person or by proxy, either in writing or by resolution adopted at an extraordinary meeting called for the purpose, at which the holders of the preferred shares shall vote separately as a class, regardless of class or series;	
 
 	•	 	purchase any preferred shares except in accordance with a purchase offer made in writing to all holders of preferred shares of all classes or series upon terms as the board, in its sole discretion after consideration of the respective annual dividend rate and other relative rights and preferences of the respective classes or series, determines, which determination shall be final and conclusive, will result in fair and equitable treatment among the respective classes or series. However, we may use shares previously acquired and then held by it as treasury stock to meet the requirements of any purchase, retirement or sinking fund provisions with respect to any class or series. In addition, nothing will prevent us from completing the purchase or redemption of preferred shares for which a purchase contract was entered into for any purchase, retirement or sinking fund purposes, or the notice of redemption of which was initially mailed, prior to the failure; and	
 
 	•	 	we may not redeem, purchase or otherwise acquire, or permit any subsidiary to purchase or acquire, any shares of any other class of our stock ranking junior to the preferred shares as to dividends and upon liquidation.	
 
Preemptive Rights
 
No holder of preferred shares, solely by reason of holding the preferred shares, has or will have any preemptive right to subscribe to any additional issue of shares of any class or series nor to any security convertible into shares.
 
7.80% Cumulative Redeemable Preferred Shares, Series C
 
In May 2003, we issued 2,300,000 shares of our 7.80% Cumulative Redeemable Preferred Shares, Series C, which we refer to as the ACE Series C Preferred Shares. The ACE Series C Preferred Shares are represented by depository shares, with each depository share representing 1/10 of an ACE Series C Preferred Share. The ACE

Table of Contents
Series C Preferred Shares rank senior to all ordinary shares now outstanding or that we may issue in the future, as to payment of dividends and distribution of assets upon our dissolution, liquidation or winding up.
 
Dividends
 
Dividends on the ACE Series C Preferred Shares are cumulative and are payable quarterly in arrears on March 1, June 1, September 1 and December 1 of each year. We will only pay dividends on the ACE Series C Preferred Shares if our board of directors or an authorized committee of our board declares those dividends payable and ACE has funds legally available to pay those dividends.
 
Dividends on the ACE Series C Preferred Shares are fixed at a rate per year of 7.80% of the liquidation preference of $250 per preferred share (or $19.50 per preferred share).
 
Optional Redemption
 
On and after May 30, 2008, we may redeem the ACE Series C Preferred Shares, in whole at any time or in part from time to time at a redemption price of $250 per ACE Series C Preferred Share, plus accrued and unpaid dividends, if any, to the date of redemption. We may not redeem the ACE Series C Preferred Shares before May 30, 2008, except as described in the next paragraph and except that we may redeem the ACE Series C Preferred Shares before that date at a redemption price of $260 per ACE Series C Preferred Share, plus accrued and unpaid dividends, if any, to the date of redemption, if we
 
 	•	 	submit a proposal to our ordinary shareholders concerning an amalgamation, merger or other similar transaction involving ACE that requires; or	
 
 	•	 	submit any proposal for any other matter that, as a result of any change in Cayman Islands law after May 7, 2003 (whether by enactment or official interpretation), requires,	
 
in either case, a vote of the holders of our ACE Series C Preferred Shares, voting separately as a single class (alone or with one or more class or series of other preferred shares).
 
We also will have the option to redeem the ACE Series C Preferred Shares, at any time in whole or in part from time to time, at a redemption price of $250 per Preferred Share, plus accrued and unpaid dividends, if any, to the date of redemption, if there is a change in tax law that would require us or any successor corporation to pay any additional or “gross up” amounts with respect to the ACE Series C Preferred Shares.
 
Voting Rights
 
The holders of the ACE Series C Preferred Shares are not entitled to any voting rights, except as required by applicable law and as described above under “Description of ACE Capital Stock—Preferred Shares—Voting Rights”. Holders of ACE Series C Preferred Shares are also entitled to vote separately as a class with respect to certain court approved schemes of arrangement or reconstruction in which we will not be the surviving entity.
 
Liquidation Rights
 
In the event of our voluntary or involuntary liquidation, dissolution or winding up, the holders of ACE Series C Preferred Shares will be entitled to receive out of our assets available for distribution to shareholders—before any distribution of assets is made on our ordinary shares or any other class or series of our stock ranking junior to the ACE Series C Preferred Shares—a liquidating distribution in the amount of $250 per share, plus an amount equal to the sum of all accumulated and unpaid dividends, whether or not earned or declared, for the then-current dividend period and all prior dividend periods.

Table of Contents
In the event our assets available for distribution to the holders of ACE Series C Preferred Shares upon any liquidation, dissolution or winding up, whether voluntary or involuntary, are insufficient to pay in full all amounts to which the holders are entitled, no distribution will be made on any other stock ranking equally with the ACE Series C Preferred Shares unless a pro rata distribution is made on the ACE Series C Preferred Shares, with the amount allocable to each series determined on the basis of the aggregate liquidation preference of the outstanding shares of each series and distributions to the shares of each series being made on a pro rata basis.
 
Transfer Agent
 
Our registrar and transfer agent for our ordinary shares and preferred shares is Mellon Investor Services.
 
Transfer of Shares
 
Our articles contain various provisions affecting the transferability of our shares. Under our articles, the board has absolute discretion to decline to register any transfer of shares for any reason, including its determination that the transfer would result in a person having controlled shares that constitute 10% or more of any class or series of ACE’s issued shares and that a registration statement under the Securities Act with respect to the shares has not been filed. However, the board has waived its right to decline to register any transfer of shares which have been traded in the public market, including any ordinary and preferred shares offered by a prospectus supplement or which were outstanding immediately prior to ACE’s initial public offering.
 
Maples and Calder, our Cayman Islands counsel, has advised us that, while the precise form of the restrictions on transfers contained in our articles is untested, as a matter of general principle, restrictions on transfers of shares are enforceable under Cayman Islands law and are not uncommon. You will be deemed to own your shares for dividend, voting and reporting purposes until a transfer of the shares has been registered on our stock transfer records.
 
The restrictions on voting and ownership of more than 10% of any class or series of our issued shares described above, as well as the provisions discussed below under “Anti-Takeover Effects of Articles of Association” and “Shareholder Rights Plan,” may have the effect of discouraging an attempt to obtain control of ACE.
 
Our articles also provide that the board may suspend the registration of transfer for any periods as the board may determine, but shall not suspend the registration of transfer for more than 45 days in any year.
 
Lloyd’s Related Requirements
 
Under Lloyd’s regulations, any person who, along with any associates, beneficially holds 10% or more of the votes or economic interest in ACE, or who controls decisions by our board, is a “controller” of any ACE subsidiary that is either a Lloyd’s corporate member or Lloyd’s managing agent. Lloyd’s imposes an absolute prohibition on any company being a controller of a Lloyd’s corporate member or Lloyd’s managing agent without first notifying Lloyd’s and receiving its consent. However, if a person breaches the 20%, 33%, 50% or majority controller thresholds, the Lloyd’s corporate member or Lloyd’s managing agent must do all that lies within its powers to comply with Lloyd’s requirements, which means that notice was given to the Council of Lloyd’s regarding the breach of the ownership percentage and that the Council did not object. Lloyd’s requires each controller to execute and deliver a declaration and undertaking to Lloyd’s with representations concerning, among other things, the absence of criminal activities, censure, insolvency, civil liabilities and government investigations. Lloyd’s also requires each controller to submit to the jurisdiction of the English courts. Any person that becomes the owner of 10% (or subsequently 20%, 33%, 50% or a majority) of our ordinary shares
 
16

Table of Contents
would have to deliver this declaration and undertaking to Lloyd’s, unless he received an exemption from Lloyd’s. The decision to grant an exemption is completely within Lloyd’s discretion.
 
In addition, under English law, if any person who is “connected with” a Lloyd’s broker holds, or subsequently becomes the holder of, more than 5% of our ordinary shares, that Lloyd’s broker risks losing its Lloyd’s license. For these purposes, a person is “connected with” a Lloyd’s broker if:
 
 	•	 	that person is the subsidiary or holding company of a corporate Lloyd’s broker or a subsidiary of a holding company;	
 
 	•	 	that person is a director of that Lloyd’s broker;	
 
 	•	 	that person is a related company that controls or is controlled by a Lloyd’s broker or any related company, which is determined by a test based on having either one-third voting rights or control of the board; or	
 
 	•	 	any person who is a partner in, or who controls or is controlled by, that Lloyd’s broker or any company which is controlled by a partner in that Lloyd’s broker or any related company of any partner or any director of any controlled or related company, if the Lloyd’s broker is a partnership.	
 
Lien on Shares
 
Our articles provide that we will have a first lien on all of our outstanding shares for all debts, liabilities or engagements to or with us, whether presently payable or not, except for shares which the board declares exempt. This lien extends to the payment of dividends or other money payable in respect of any ordinary shares or preferred shares subject to the lien. In addition, our directors may deduct from any dividend payable to you all sums of money presently payable by you to us on any account. However, the board has exempted the ordinary and preferred shares offered by any prospectus supplement from these provisions.
 
Anti-Takeover Effects of our Articles
 
Our articles contain provisions that make it more difficult for an entity to acquire control of ACE by means of a tender offer, open market purchase, proxy fight or otherwise. These provisions, as well as the shareholder rights plan described under “Shareholder Rights Plan” below, are designed to encourage persons seeking to acquire control of ACE to negotiate with our directors. We believe that, as a general rule, your interests would be best served if any change in control results from negotiations with our directors, who would negotiate based upon careful consideration of the proposed terms, including the price, the form of consideration and the anticipated tax effects of the transaction. However, these provisions could have the effect of discouraging a prospective acquiror from making a tender offer or otherwise attempting to obtain control of ACE, which could deprive you of opportunities to realize takeover premiums for your shares or could depress the market price of your shares.
 
No Shareholder Action by Written Consent
 
Our articles provide that shareholders must take any action required or permitted to be taken by them at a annual general or extraordinary general meeting of its shareholders and may not be taken by written consent or otherwise. The affirmative vote of the holders of at least 66  2 / 3 % of the outstanding shares is required to amend or repeal, or adopt any provision inconsistent with, this provision of our articles.
 
Availability of Shares of Capital Stock for Future Issuances
 
Our directors may issue shares without further action by shareholders, including by issuing warrants or rights to acquire shares to discourage or defeat unsolicited stock accumulation programs and acquisition
 
17

Table of Contents
proposals and by issuing shares in a private placement or public offering to dilute or deter stock ownership of persons seeking to obtain control of ACE. This could be enable the directors to make it more difficult for someone to effect a change in control of ACE.
 
Shareholder Proposals
 
Our articles provide that if you desire to submit a proposal for consideration at either an annual or extraordinary general meeting, or to nominate persons for election as directors, you must submit written notice of your intent to make the proposal or nomination to ACE’s Secretary at our principal executive offices. This notice must be received not later than 60 days prior to the anniversary date of the immediately preceding annual general meeting or, with respect to an extraordinary general meeting, the close of business on the tenth day following the date on which the notice is first sent or given to shareholders. This notice must describe the proposal or nomination in sufficient detail and must set forth the following information:
 
 	•	 	your name and address;	
 
 	•	 	a representation that you are a holder of record of shares of ACE entitled to vote at the meeting and you intend to appear in person or by proxy at the meeting to present the proposal or nomination;	
 
 	•	 	the class and number of shares of ACE that are beneficially owned by you; and	
 
 	•	 	the reasons for conducting the proposed business at the meeting and any material interest of yours in the business.	
 
In addition, a notice with regard to a nomination of any person for election as a director must also contain:
 
 	•	 	the name and address of any person to be nominated;	
 
 	•	 	a description of all arrangements or understandings between you and each nominee and any other person or persons;	
 
 	•	 	any other information regarding the nominee as would be required to be included in a proxy statement; and	
 
 	•	 	the consent of each nominee to serve as a director of ACE, if so elected.	
 
The presiding officer of the annual general meeting or extraordinary general meeting will, if the facts warrant, refuse to acknowledge a proposal or nomination not properly made.
 
This advance notice for shareholders’ proposals provision may have the effect of precluding a contest for the election of directors or the introduction of a shareholder proposal and may discourage or deter a third party from conducting a solicitation of proxies to elect its own slate of directors or to introduce a proposal. The affirmative vote of the holders of at least 66  2 / 3 % of the outstanding shares will be required to amend or repeal, or adopt any provision inconsistent with, this provision.
 
Shareholder Rights Plan
 
On May 7, 1999, our board declared a dividend of one preference share purchase right for each outstanding ordinary share to shareholders of record at the close of business on June 1, 1999. Generally, each right, entitles the holder to purchase from us one one-thousandth of a series A junior participating preference share at an exercise price of $150, subject to antidilution adjustments. Because of the nature of the preference shares’ dividend, liquidation and voting rights, the value of the one one-thousandth of a preference share should approximate the value of one ordinary share.
 
18

Table of Contents
These purchase rights generally will only be exercisable:
 
 	•	 	10 days following a public announcement that a person or a group of affiliated or associated persons has acquired, or obtained the right to acquire, 15% or more of our outstanding ordinary shares; or	
 
 	•	 	15 business days following the commencement of, or the announcement of an intention to make, a tender or exchange offer for 15% or more of our outstanding ordinary shares.	
 
Generally, if any person or group acquires, or obtains the right to acquire, 15% or more of our outstanding ordinary shares, each right, except for rights held by this person or group, will entitle its holder to purchase ordinary shares having a value equal to two times the exercise price of the right. If ACE is acquired in a merger, amalgamation or other business combination transaction, or if 50% or more of ACE’s assets or earnings power is sold, then proper provision will be made so that each holder of a right, except for a person or group acquiring, or obtaining the right to acquire, 15% or more of our outstanding ordinary shares, will be entitled to receive common stock of the acquiring or surviving company having a value equal to two times the exercise price of the right.
 
In addition, our board has the option, at any time after any person or group acquires, or obtains the right to acquire, 15% or more of our outstanding ordinary shares, but before they acquires 50% or more of our outstanding ordinary shares, to exchange each right, except for rights held by this person or group, for one ordinary share. Further, at any time prior to the time that any person or group acquires, or obtains the right to acquire, 15% or more of our outstanding ordinary shares, our board may redeem the rights in whole, but not in part, at a price of $0.01 per right. These rights will expire on June 1, 2009 if they have not been previously exercised, exchanged or redeemed.

 DESCRIPTION OF THE DEPOSITARY SHARES
 
General
 
We may offer depositary shares, each representing a specified fraction of a share of a particular series of preferred shares. Depositary receipts evidencing depositary shares will be issued to those persons purchasing the fractional shares of the related preferred shares.
 
The shares of any class or series of preferred shares represented by depositary shares will be deposited under a deposit agreement among ACE, a depositary selected by ACE and the holders of the depositary receipts, whom we refer to in this section as owners. Subject to the terms of the deposit agreement, each owner will be entitled to all the rights and preferences of the preferred shares represented by the depositary share in proportion to the fraction of a preferred share represented by the depositary share, including dividend, voting, redemption and liquidation rights.
 
Dividends and Other Distributions
 
The depositary will distribute all cash dividends or other distributions received on the related preferred shares to the owners in proportion to the number of depositary shares owned. In the event of a distribution other than in cash, the depositary will distribute property received by it to the owners, unless the depositary determines that it is not feasible to make the distribution, in which case the depositary may, with our approval, sell the property and distribute the net proceeds from the sale to the owners.
 
Withdrawal of Shares
 
Upon surrender of the depositary receipts, unless the related depositary shares have previously been called for redemption, the owner is entitled to delivery of the number of whole shares of the related preferred shares and any money or other property represented by his depositary shares. Holders of the whole preferred shares will not be entitled to exchange the preferred shares for depositary shares. If the delivered depositary receipts evidence a number of depositary shares in excess of the number of whole preferred shares to be withdrawn, the depositary will deliver to the owner a new depositary receipt evidencing this excess number at the same time. In no event will fractional preferred shares be delivered upon surrender of depositary receipts.
 
Redemption of Depositary Shares
 
Whenever we redeem preferred shares held by the depositary, the depositary will redeem the number of depositary shares representing the related preferred shares. The redemption price per depositary share will be equal to the applicable fraction of the redemption price per preferred share. If less than all the depositary shares are to be redeemed, the depositary shares to be redeemed will be selected by lot or pro rata as may be determined by the depositary or us.
 
Voting the Preferred Shares
 
Upon receipt of notice of any meeting at which the holders of the preferred shares are entitled to vote, the depositary will mail the information contained in the notice to the record owners of the depositary shares. Each record owner on the record date, which will be the same as the record date for the preferred shares, may instruct the depositary how to exercise its voting rights pertaining to the preferred shares represented by the owner’s depositary shares. The depositary will endeavor, insofar as practicable, to vote the number of the preferred shares represented by these depositary shares in accordance with the instructions, and we will agree to take all action which the depositary deems necessary in order to enable the depositary to do so. The depositary will not vote preferred shares if it does not receive specific instructions from the record owners.

Amendment and Termination of the Deposit Agreement
 
Unless otherwise provided in the applicable prospectus supplement, the form of depositary receipt and any provision of the deposit agreement may be amended at any time by agreement between us and the depositary. However, any amendment which materially and adversely alters the rights of the owners will not be effective unless it has been approved by the owners representing at least a majority, or, in the case of amendments affecting rights to receive dividends or distributions or voting or redemption rights, 66  2 / 3 % of the depositary shares then outstanding. We or the depositary may terminate the deposit agreement only:
 
 	•	 	if all outstanding depositary shares have been redeemed;	
 
 	•	 	if there has been a final distribution on the preferred shares in connection with any liquidation, dissolution or winding up of ACE and the distribution has been distributed to the owners; or	
 
 	•	 	with the consent of owners representing not less than 66  2 / 3 % of the depositary shares outstanding.	
 
Charges of Depositary
 
We will pay all transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangements. We will also pay charges of the depositary in connection with the initial deposit of preferred shares and any redemption of the preferred shares. Owners will pay all other transfer and other taxes and governmental charges and any other charges as are expressly provided in the deposit agreement to be for their accounts.
 
The depositary may refuse to transfer a depositary receipt or any withdrawal of preferred shares evidenced by the depositary receipts until all taxes and charges with respect to the receipts or preferred shares are paid by the owners.
 
Miscellaneous
 
The depositary will forward all reports and communications which it receives from us and which we are required to furnish to the holders of the preferred shares.
 
Neither the depositary nor we will be liable if the depositary is prevented or delayed by law or any circumstance beyond its control in performing its obligations under the deposit agreement. Our and the depositary’s obligations will be limited to performance of the duties under the deposit agreement in a manner that does not constitute bad faith, and neither we nor the depositary will be obligated to prosecute or defend any legal proceeding in respect of any depositary or preferred shares unless satisfactory indemnity is furnished.
 
Resignation and Removal of Depositary
 
The depositary may resign at any time by delivering to us notice of its election to resign, and we may at any time remove the depositary. Any resignation or removal of the depositary will take effect upon the appointment of a successor depositary, which successor depositary must be appointed within 60 days after delivery of the notice of resignation or removal and must be a bank or trust company having its principal office in the United States and having a combined capital and surplus of at least $50,000,000 or be an affiliate of such bank or trust company.

 DESCRIPTION OF ACE DEBT SECURITIES
 
The following description of the ACE debt securities sets forth the material terms and provisions of the ACE debt securities. The ACE senior debt securities will be issued under an indenture, referred to in this prospectus as the ACE senior indenture, between us and J.P. Morgan Trust Company, National Association (as successor to The First National Bank of Chicago), as trustee, dated as of March 15, 2002, a copy of which is incorporated by reference as an exhibit to the registration statement of which this prospectus forms a part. The ACE subordinated debt securities will be issued under an indenture, referred to in this prospectus as the ACE subordinated indenture, between us and J.P. Morgan Trust Company, National Association, as trustee, the form of which is incorporated by reference as an exhibit to the registration statement of which this prospectus forms a part. The ACE senior indenture and the ACE subordinated indenture are sometimes referred to in this prospectus collectively as the ACE indentures and each individually as an ACE indenture. The specific terms applicable to a particular issuance of ACE debt securities and any variations from the terms set forth below will be set forth in the applicable prospectus supplement.
 
The following is a summary of the material terms and provisions of the ACE indentures and the ACE debt securities. You should refer to the forms of the ACE indentures and the ACE debt securities for complete information regarding the terms and provisions of the ACE indentures and the ACE debt securities. The ACE indentures are substantially identical, except for the covenants of ACE and provisions relating to subordination.
 
General
 
The ACE indentures do not limit the aggregate principal amount of ACE debt securities which we may issue. We may issue ACE debt securities under the ACE indentures from time to time in one or more series. The ACE indentures do not limit the amount of other indebtedness, or ACE debt securities other than secured indebtedness, which we or our subsidiaries may issue.
 
Unless otherwise provided in a prospectus supplement, the ACE senior debt securities will be our unsecured obligations and will rank equally with all of our other unsecured and unsubordinated indebtedness. The ACE subordinated debt securities will be our unsecured obligations and will be subordinated in right of payment to the prior payment in full of all of our senior indebtedness, which term includes ACE senior debt securities, as described below under “Subordination of ACE Subordinated Debt Securities.”
 
Because we are a holding company, our rights and the rights of our creditors, including you, as a holder of ACE debt securities, and shareholders to participate in any distribution of assets of any subsidiary upon the subsidiary’s liquidation or reorganization or otherwise would be subject to the prior claims of the subsidiary’s creditors, except to the extent that we are a creditor of the subsidiary. The right of our creditors, including you, to participate in the distribution of stock owned by us in some of our subsidiaries, including our insurance subsidiaries, may also be subject to approval by insurance regulatory authorities having jurisdiction over these subsidiaries.
 
Each prospectus supplement will describe the following terms of the offered ACE debt securities:
 
 	•	 	the title of the series;	
 
 	•	 	any limit on the aggregate principal amount;	
 
 	•	 	the principal payment dates;	
 
 	•	 	the interest rates, if any, which rate may be zero if the ACE debt securities are issued at a discount from the principal amount payable at maturity, or the method by which the interest rates will be determined, including, if applicable, any remarketing option or similar method;

We will have the ability under the ACE indentures to “reopen” a previously issued series of ACE debt securities and issue additional ACE debt securities of that series or establish additional terms of that series. We are also permitted to issue ACE debt securities with the same terms as previously issued ACE debt securities.
 
Unless otherwise set forth in the applicable prospectus supplement, principal of premium and interest on and additional amounts, if any, on the ACE debt securities will initially be payable at the corporate trust office of the trustee or any other office or agency designated by us. Interest on ACE debt securities issued in registered form:
 
 	•	 	may be paid by check mailed to the persons entitled to the payments at their addresses appearing on the security register or by transfer to an account maintained by the payee with a bank located in the United States; and	
 
 	•	 	will be payable on any interest payment date to the persons in whose names the ACE debt securities are registered at the close of business on the regular record date with respect to the interest payment date.	
 
We will designate the initial paying agents, which will be named in the applicable prospectus supplement, and may, at any time, designate additional paying agents, rescind the designation of any paying agent or approve a change in the office through which any paying agent acts. However, we are required to maintain a paying agent in each place where the principal of, any premium or interest on or any additional amounts with respect to the ACE debt securities are payable.
 
Unless otherwise set forth in the applicable prospectus supplement, you may present the ACE debt securities for transfer, duly endorsed or accompanied by a written instrument of transfer if so required by ACE or the security registrar, or exchange for other ACE debt securities of the same series containing identical terms and provisions, in any authorized denominations, and of a like aggregate principal amount, in each case at the office or agency maintained by us for this purposes, which will initially be the corporate trust office of the trustee. Any transfer or exchange will be made without service charge, although we may require payment of a sum sufficient to cover any tax or other governmental charge and any other expenses then payable. ACE is not required to:
 
 	•	 	issue, register the transfer of, or exchange ACE debt securities during a period beginning at the opening of business 15 days before the day of mailing of a notice of redemption of any ACE debt securities and ending at the close of business on the day of mailing; or	
 
24

Table of Contents

 	•	 	register the transfer of or exchange any ACE debt security selected for redemption, in whole or in part, except the unredeemed portion of any ACE debt security being redeemed in part. (Section 3.5)	
 
Unless otherwise set forth in the applicable prospectus supplement, we will only issue the ACE debt securities in fully registered form without coupons in minimum denominations of $1,000 and any integral multiple of $1,000. (Section 3.2) If the ACE debt securities are issued in bearer form, any restrictions and considerations, including offering restrictions and U.S. Federal income tax considerations applicable to these securities, and to payment on and transfer and exchange of, these securities, will be described in the applicable prospectus supplement.
 
The ACE debt securities may be issued as original issue discount securities, which means that they will bear no interest or bear interest at a rate which, at the time of issuance, is below market rates. ACE debt securities issued as original issue discount securities will be sold at a substantial discount below their principal amount.
 
U.S. Federal income tax and other considerations applicable to original issue discount securities will be described in the applicable prospectus supplement.
 
If the purchase price, or the principal of, or any premium or interest on, or any additional amounts with respect to, any ACE debt securities is payable in, or if any ACE debt securities are denominated in, one or more foreign currencies or currency units, the restrictions, elections, U.S. Federal income tax considerations, specific terms and other information will be set forth in the applicable prospectus supplement.
 
Unless otherwise set forth in the applicable prospectus supplement, other than as described below under “—Covenants Applicable to ACE Senior Debt Securities—Limitation on Liens on Stock of Designated Subsidiaries,” the ACE indentures do not limit our ability to incur indebtedness or protect holders of the ACE debt securities in the event of a sudden and significant decline in our credit quality or a takeover, recapitalization or highly leveraged or similar transaction involving us. Accordingly, we could in the future enter into transactions that could increase the amount of its outstanding indebtedness or otherwise affect its capital structure or credit rating.
 
Conversion and Exchange
 
The terms, if any, on which ACE debt securities are convertible into or exchangeable for, either mandatorily, at our or your option, property or cash, ordinary shares, preferred shares or other securities, whether or not issued by us, or a combination of any of these, will be set forth in the applicable prospectus supplement.
 
Global Securities
 
The ACE debt securities may be issued, in whole or in part, in the form of one or more global securities that will be deposited with, or on behalf of, a depositary identified in the applicable prospectus supplement and registered in the name of the depositary or its nominee. Interests in any global ACE debt security will be shown on, and transfers of the ACE debt securities will be effected only through, records maintained by the depositary and its participants as described below.
 
The specific terms of the depositary arrangement will be described in the applicable prospectus supplement.

Payment of Additional Amounts
 
We will make all payments on the ACE debt securities without withholding of any present or future taxes or governmental charges of the jurisdiction of ACE’s organization or principal executive offices (each, a “taxing jurisdiction”), unless we are required to do so by applicable law or regulation.
 
If under the laws or regulations of a taxing jurisdiction we are required to withhold amounts, we will, subject to the limitations described below, pay to you additional amounts so that every net payment made to you, after the withholding, will be the same amount provided for in the ACE debt security and the applicable ACE indenture.
 
We will not be required to pay any additional amounts for:
 
 	•	 	any tax or governmental charge which would not have been imposed but for the fact that you:	
 
 	•	 	were a resident of, or engaged in business or maintained a permanent establishment or were physically present in, the relevant taxing jurisdiction or otherwise had some connection with the relevant taxing jurisdiction other than the mere ownership of, or receipt of payment on, the ACE debt security,	
 
 	•	 	presented the ACE debt security for payment in the relevant taxing jurisdiction, unless the ACE debt security could not have been presented for payment elsewhere, or	
 
 	•	 	presented the ACE debt security for payment more than 30 days after the date on which the payment became due unless you would have been entitled to these additional amounts if you had presented the ACE debt security for payment within the 30-day period;	
 
 	•	 	any estate, inheritance, gift, sale, transfer, personal property or similar tax or other governmental charge;	
 
 	•	 	any tax or other governmental charge that is imposed or withheld because of your failure to comply with any reasonable request by us:	
 
 	•	 	to provide information concerning your nationality, residence or identity or that of the beneficial owner; or	
 
 	•	 	to make any claim or satisfy any information or reporting requirement, which in either case is required by the relevant taxing jurisdiction as a precondition to exemption from all or part of the tax or other governmental charge; or	
 
 	•	 	any combination of the above items.	
 
In addition, we will not pay additional amounts if you are a fiduciary or partnership or other than the sole beneficial owner of the ACE debt security if the beneficiary or partner or settlor would not have been entitled to the additional amounts had it been the holder of the ACE debt security. (Section 10.4)
 
Covenants Applicable to ACE Senior Debt Securities
 
Limitation on Liens on Stock of Designated Subsidiaries
 
Under the ACE senior indenture, we will covenant that, so long as any ACE senior debt securities are outstanding, we will not, nor will we permit any subsidiary to, create, incur, assume or guarantee or otherwise permit to exist any indebtedness secured by any security interest on any shares of capital stock of any designated subsidiary unless we concurrently provide that the ACE senior debt securities and, if we elect, any other indebtedness that is not subordinate to the ACE senior debt securities and with respect to which the governing instruments require, or pursuant to which we are obligated, to provide such security, will be secured equally with this indebtedness for at least the time period this other indebtedness is so secured. (Section 10.5 of the ACE senior indenture)
 
26

Table of Contents
The term “designated subsidiary” means any present or future consolidated subsidiary, the consolidated net worth of which constitutes at least 5% of our consolidated net worth. (Section 1.1 of the ACE senior indenture).
 
For purposes of the ACE indentures, the term “indebtedness” means, with respect to any person:
 
 	•	 	the principal of and any premium and interest on:	
 
 	•	 	indebtedness for money borrowed and	
 
 	•	 	indebtedness evidenced by notes, debentures, bonds or other similar instruments for the payment of which the person is responsible or liable;	
 
 	•	 	all capitalized lease obligations;	
 
 	•	 	all obligations issued or assumed as the deferred purchase price of property, all conditional sale obligations and all obligations under any title retention agreement, but excluding trade accounts payable arising in the ordinary course of business;	
 
 	•	 	all obligations for the reimbursement of any obligor on any letter of credit, banker’s acceptance or similar credit transaction, generally other than obligations with respect to letters of credit securing obligations (other than the obligations described above), entered into in the ordinary course of business to the extent these letters of credit are not drawn upon or, if and to the extent drawn upon, such drawing is reimbursed no later than the third business day following receipt by the person of a demand for reimbursement following payment or a letter of credit;	
 
 	•	 	all obligations of the type referred to above of other persons and all dividends of other persons for the payment of which, in either case, the person is responsible or liable as obligor, guarantor or otherwise;

 	•	 	any amendments, modifications, refundings, renewals or extensions of any indebtedness or obligation described above. (Section 1.1)	
 
Limitations on Disposition of Stock of Designated Subsidiaries
 
The ACE senior indenture also provides that, so long as any ACE senior debt securities are outstanding and except in a transaction otherwise governed by the ACE indentures, we will not issue, sell, assign, transfer or otherwise dispose of any shares of, securities convertible into, or warrants, rights or options to subscribe for or purchase shares of, capital stock, other than preferred stock having no voting rights, of any designated subsidiary. Similarly, we will not permit any designated subsidiary to issue, other than to us, these types of securities, warrants, rights or options, other than director’s qualifying shares and preferred stock having no voting rights, of any designated subsidiary, if, after giving effect to the transaction and the issuance of the maximum number of shares issuable upon the conversion or exercise of all the convertible securities, warrants, rights or options, we would own, directly or indirectly, less than 80% of the shares of capital stock of the designated subsidiary, other than preferred stock having no voting rights.
 
However, we may issue, sell, assign, transfer or otherwise dispose of securities if the consideration is at least a fair market value as determined by our board or if required by law or regulation. We may also merge or consolidate any designated subsidiary into or with another direct or indirect subsidiary, the shares of capital stock of which we own at least 80% or, subject to the provisions described under “—Consolidation, Amalgamation, Merger and Sale of Assets” below, sell, transfer or otherwise dispose of the entire capital stock of any designated

subsidiary at one time if the consideration is at least fair market value as determined by our board. (Section 10.6 of the ACE senior indenture)
 
Consolidation, Amalgamation, Merger and Sale of Assets
 
Each ACE indenture provides that we may not:
 
 	•	 	consolidate or amalgamate with or merge into any person or convey, transfer or lease its properties and assets as an entirety or substantially as an entirety to any person, or	
 
 	•	 	permit any person to consolidate or amalgamate with or merge into us, or convey, transfer or lease its properties and assets as an entirety or substantially as an entirety to us,	
 
unless,
 
 	•	 	the person is a corporation organized and existing under the laws of the United States of America, any state of the U.S., the District of Columbia, Bermuda, the Cayman Islands or any other country that, on March 15, 2002, was a member of the Organization for Economic Cooperation and Development;	
 
 	•	 	the surviving entity expressly assumes the payment of all amounts on all of the ACE debt securities and the performance of our obligations under the ACE indenture and the ACE debt securities;	
 
 	•	 	the surviving entity provides for conversion or exchange rights in accordance with the provisions of the ACE debt securities of any series that are convertible or exchangeable into ordinary shares or other securities; and	
 
 	•	 	immediately after giving effect to the transaction and treating any indebtedness which becomes our an obligation as a result of the transaction as having been incurred by us at the time of the transaction, no event of default, and no event which after notice or lapse of time or both would become an event of default, will have happened and be continuing. (Section 8.1)	
 
Events of Default
 
Each of the following events will constitute an event of default under each ACE indenture:
 
 	•	 	default in the payment of any interest on, or any additional amounts payable with respect to, any ACE debt security when the interest or additional amounts become due and payable, and continuance of this default for a period of 30 days;	
 
 	•	 	default in the payment of the principal of or any premium on, or any additional amounts payable with respect to, any ACE debt security when the principal, premium or additional amounts become due and payable either at maturity, upon any redemption, by declaration of acceleration or otherwise;	
 
 	•	 	default in the deposit of any sinking fund payment, when due;	
 
 	•	 	default in the performance, or breach, of any covenant or warranty for the benefit of the holders of the ACE debt securities, and the continuance of this default or breach for a period of 60 days after we have received written notice from the holders;	
 
 	•	 	if any event of default under a mortgage, indenture or instrument under which we issue, or by which we secure or evidence, any of indebtedness, including an event of default under any other series of ACE debt securities, whether the indebtedness now exists or is later created or incurred, happens and consists of default in the payment of more than $50,000,000 in principal amount of indebtedness at the maturity of the indebtedness, after giving effect to any applicable grace period, or results in the indebtedness in principal amount in excess of $50,000,000 becoming or being declared due and payable prior to the date	
 
28

Table of Contents

 	on which it would otherwise become due and payable, and this default is not cured or the acceleration is not rescinded or annulled within a period of 30 days after ACE has received written notice;	
 
 	•	 	we fail within 60 days to pay, bond or otherwise discharge any uninsured judgment or court order for the payment of money in excess of $50,000,000, which is not stayed on appeal or is not otherwise being appropriately contested in good faith;	
 
 	•	 	our bankruptcy, insolvency or reorganization; and	
 
 	•	 	any other event of default, which will be described in the applicable prospectus supplement. (Section 5.1)	
 
If an event of default with respect to the ACE debt securities of any series, other than events of bankruptcy, insolvency or reorganization, occurs and is continuing, either the trustee or the holders of not less than 25% in principal amount of the outstanding ACE debt securities of the series may declare the principal amount, or a lesser amount as may be provided for in the ACE debt securities, of all outstanding ACE debt securities of the series to be immediately due and payable by written notice. At any time after a declaration of acceleration has been made, but before a judgment or decree for payment of money has been obtained by the trustee, generally, the holders of not less than a majority in principal amount of the ACE debt securities of the series may rescind and annul the declaration of acceleration. Any event of bankruptcy, insolvency or reorganization will cause the principal amount and accrued interest, or the lesser amount as provided for in the ACE debt securities, to become immediately due and payable without any declaration or other act by the trustee or any holder. (Section 5.2)
 
Each ACE indenture provides that, within 90 days after the occurrence of any event which is, or after notice or lapse of time or both would become, an event of default the trustee will transmit notice of the default to each holder of the ACE debt securities unless the default has been cured or waived. However, except in the case of a default in the payment of principal of, or premium, or interest, if any, on or additional amounts or any sinking fund or purchase fund installment with respect to any ACE debt security, the trustee may withhold this notice if and so long as the board of directors, executive committee or trust committee of directors and/or responsible officers of the trustee determines in good faith that the withholding of the notice is in the best interest of the holders. (Section 6.2)
 
If an event of default occurs and is continuing with respect to the ACE debt securities of any series, the trustee may, in its discretion, proceed to protect and enforce its rights and the rights of the holders of ACE debt securities by all appropriate judicial proceedings. (Section 5.3) Each ACE indenture provides that, subject to the duty of the trustee during any default to act with the required standard of care, the trustee will be under no obligation to exercise any of its rights or powers under the ACE indenture at the request or direction of any of the holders, unless the holders have offered the trustee reasonable indemnity. (Section 6.1) Subject to these indemnification provisions, the holders of a majority in principal amount of the outstanding ACE debt securities of any series will generally have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred on the trustee, with respect to the ACE debt securities of the series. (Section 5.12)

Modification and Waiver
 
ACE and the trustee may modify or amend either ACE indenture with the consent of the holders of not less than a majority in principal amount of the outstanding ACE debt securities of each series affected by the modification or amendment, so long as the modification or amendment does not, without the consent of each affected holder:
 
 	•	 	change the stated maturity of the principal of, any premium or installment of interest on or any additional amounts with respect to any ACE debt security,

 	•	 	change the place of payment or the coin or currency in which the principal of, any premium or interest on or any additional amounts with respect to any ACE debt security is payable,	
 
 	•	 	impair the right to institute suit for the enforcement of any payment on or after the stated maturity of any ACE debt security or, in the case of redemption, on or after the redemption date or, in the case of repayment at the option of any holder, on or after the repayment date,	
 
 	•	 	reduce the percentage in principal amount of the outstanding ACE debt securities, the consent of whose holders is required in order to take specific actions,	
 
 	•	 	reduce the requirements for quorum or voting by holders of ACE debt securities in specified circumstances,	
 
 	•	 	modify any of the provisions regarding the waiver of past defaults and the waiver of specified covenants by the holders of ACE debt securities, except to increase any percentage vote required or to provide that other provisions of the ACE indenture cannot be modified or waived without the consent of the holder of each ACE debt security affected by the modification,	
 
 	•	 	make any change that adversely affects the right to convert or exchange any ACE debt security into or for ordinary shares of ACE or other securities, whether or not issued by ACE, cash or property in accordance with its terms,	
 
 	•	 	modify any of the provisions of the ACE subordinated indenture relating to the subordination of the ACE subordinated debt securities in a manner adverse to holders of ACE subordinated debt securities, or	
 
 	•	 	modify any of the above provisions. (Section 9.2)	
 
In addition, no supplemental indenture may, directly or indirectly, modify or eliminate the subordination provisions of the ACE subordinated indenture in any manner which might terminate or impair the subordination of the ACE subordinated debt securities of any series to senior indebtedness without the prior written consent of the holders of the senior indebtedness. (Section 9.7 of the ACE subordinated indenture)

ACE and the trustee may modify or amend either ACE indenture and the ACE debt securities of any series without the consent of any holder in order to, among other things:
 
 	•	 	provide for a successor to ACE pursuant to a consolidation, amalgamation, merger or sale of assets;	
 
 	•	 	add to the covenants of ACE for the benefit of the holders of all or any series of ACE debt securities or to surrender any right or power conferred upon ACE;	
 
 	•	 	provide for a successor trustee with respect to the ACE debt securities of all or any series;

 	•	 	change the conditions, limitations and restrictions on the authorized amount, terms or purposes of issue, authentication and delivery of ACE debt securities;	
 
 	•	 	add any additional events of default with respect to all or any series of ACE debt securities;

 	•	 	provide for conversion or exchange rights of the holders of any series of ACE debt securities; or	
 
 	•	 	make any other change that does not materially adversely affect the interests of the holders of any ACE debt securities then outstanding. (Section 9.1)	
 
The holders of at least a majority in principal amount of the outstanding ACE debt securities of any series may, on behalf of the holders of all ACE debt securities of that series, waive compliance by ACE with specified covenants. (Section 10.8 of the ACE senior indenture; Section 10.6 of the ACE subordinated indenture) The holders of not less than a majority in principal amount of the outstanding ACE debt securities of any series may, on behalf of the holders of all ACE debt securities of that series, waive any past default and its consequences with respect to the ACE debt securities of that series, except a default:
 
 	•	 	in the payment of principal of, any premium or interest on or any additional amounts with respect to ACE debt securities of that series; or	
 
 	•	 	in respect of a covenant or provision that cannot be modified or amended without the consent of the holder of each outstanding ACE debt security of any series affected. (Section 5.13)	
 
Under each ACE indenture, ACE must annually furnish the trustee annually a statement regarding its performance of specified obligations and any default in its performance under the applicable ACE indenture. ACE is also required to deliver to the trustee, within five days after its occurrence, written notice of any event of default, or any event which after notice or lapse of time or both would constitute an event of default, resulting from the failure to perform, or breach of, any covenant or warranty contained in the applicable ACE indenture or the ACE debt securities. (Section 10.9 of the ACE senior indenture; Section 10.7 of the ACE subordinated indenture)
 
Discharge, Defeasance and Covenant Defeasance
 
We may discharge our payment obligations on the ACE debt securities, which we refer to as defeasance, or elect to be discharged from complying with the covenants in the ACE indentures, except for certain ministerial obligations, like registering transfers or exchanges of the ACE debt securities, which we refer to as covenant defeasance.
 
Defeasance or covenant defeasance, as the case may be, will be conditioned upon the irrevocable deposit by us with the trustee, in trust, of a cash amount or government obligations, or both, which, through the scheduled
 
31

Table of Contents
payment of principal and interest in accordance with their terms, will provide money in an amount sufficient to pay the principal of, any premium and interest on and any additional amounts with respect to, the ACE debt securities on the scheduled due dates. (Section 4.2)
 
We may only do this if, among other things:
 
 	•	 	the defeasance or covenant defeasance does not result in a breach or violation of, or constitute a default under, the applicable ACE indenture or any other material agreement or instrument to which ACE is a party or by which it is bound;	
 
 	•	 	no event of default or event which with notice or lapse of time or both would become an event of default with respect to the ACE debt securities to be defeased will have occurred and be continuing on the date of establishment of the trust and, with respect to defeasance only, at any time during the period ending on the 123rd day after that date; and	
 
 	•	 	we has delivered to the trustee an opinion of counsel to the effect that you will not recognize income, gain or loss for U.S. Federal income tax purposes as a result of the defeasance or covenant defeasance and will be subject to U.S. Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if the defeasance or covenant defeasance had not occurred. The opinion of counsel, in the case of defeasance, must refer to and be based upon a letter ruling of the I.R.S. received by us, a revenue ruling published by the I.R.S. or a change in applicable U.S. Federal income tax law occurring after the date of the applicable ACE indenture. (Section 4.2)	
 
Subordination of ACE Subordinated Debt Securities
 
The ACE subordinated debt securities will generally be subordinate in right of payment to the prior payment in full of all senior indebtedness. (Section 16.1 of the ACE subordinated indenture) Upon any payment or distribution of our assets, whether in cash, property or securities, to creditors upon our dissolution, winding-up, liquidation or reorganization, whether voluntary or involuntary, or in bankruptcy, insolvency, receivership or other proceedings, all amounts due upon all senior indebtedness will first be paid in full, or payment provided for in money in accordance with its terms, before the holders of ACE subordinated debt securities are entitled to receive or retain any payment on account of principal of, or any premium or interest on or any additional amounts with respect to the ACE subordinated debt securities. This means that the holders of senior indebtedness will be entitled to receive any payment or distribution of any kind or character, including any payment or distribution which may be payable or deliverable by reason of the payment of any other indebtedness of ACE being subordinated to the payment of ACE subordinated debt securities, which may be payable or deliverable in respect of the ACE subordinated debt securities upon any dissolution, winding-up, liquidation or reorganization or in any bankruptcy, insolvency, receivership or other proceeding. (Section 16.3 of the ACE subordinated indenture)
 
By reason of subordination, in the event of our liquidation or insolvency, holders of our senior indebtedness and holders of our other obligations that are not subordinated to senior indebtedness may recover more ratably than the holders of the ACE subordinated debt securities.
 
Subject to the payment in full of all senior indebtedness, your rights, as a holder of the ACE subordinated debt securities, will be subrogated to the rights of the holders of senior indebtedness to receive payments or distributions of our cash, property or securities applicable to the senior indebtedness until the principal of, any premium and interest on and any additional amounts with respect to the ACE senior debt securities have been paid in full. (Section 16.4 of the ACE subordinated indenture)
 
32

Table of Contents
No payment of principal of, including redemption and sinking fund payments, or any premium or interest on or any additional amounts with respect to the ACE subordinated debt securities of any series may be made:
 
 	•	 	if any senior indebtedness is not paid when due and any applicable grace period with respect to the default has ended and has not been cured or waived or ceased to exist, or	
 
 	•	 	if the maturity of any senior indebtedness has been accelerated because of a default. (Section 16.2 of the ACE subordinated indenture)	
 
The ACE subordinated indenture does not limit or prohibit us from incurring additional senior indebtedness, which may include indebtedness that is senior to the ACE subordinated debt securities but subordinate to our other obligations. The ACE senior debt securities will constitute senior indebtedness with respect to the ACE subordinated debt securities.
 
The term “senior indebtedness” means all indebtedness of ACE outstanding at any time, except:
 
 	•	 	the ACE subordinated debt securities of the series;	
 
 	•	 	indebtedness as to which, by the terms of the instrument creating or evidencing the indebtedness, it is provided that the indebtedness is subordinated to or ranks equally with the ACE subordinated debt securities;	
 
 	•	 	indebtedness to an affiliate;	
 
 	•	 	interest accruing after the filing of a petition initiating any bankruptcy, insolvency or other similar proceeding unless the interest is an allowed claim enforceable against ACE in a proceeding under federal or state bankruptcy laws; and	
 
 	•	 	trade accounts payable.	
 
Senior indebtedness will continue to be senior indebtedness and be entitled to the benefits of the subordination provisions irrespective of any amendment, modification or waiver of any term of the senior indebtedness. (Sections 1.1 and 16.8 of the ACE subordinated indenture)
 
The ACE subordinated indenture provides that these subordination provisions may be changed prior to issuance of the ACE subordinated debt securities. Any change would be described in the applicable prospectus supplement.
 
New York Law to Govern
 
The ACE indentures and the ACE debt securities will be governed by, and construed in accordance with, the laws of the state of New York. (Section 1.13)
 
Information Concerning the Trustee
 
We may, from time to time, borrow from or maintain deposit accounts and conduct other banking transactions with J.P. Morgan Trust Company, National Association and its affiliates in the ordinary course of business.
 
Under each ACE indenture, J.P. Morgan Trust Company, National Association is required to transmit annual reports to all holders regarding its eligibility and qualifications as trustee under the applicable ACE indenture and related matters. (Section 7.3)

The specific terms applicable to a particular issuance of ACE INA debt securities and any variations from the terms set forth below will be set forth in the applicable prospectus supplement.
 
The following is a summary of the material terms and provisions of the ACE INA indentures, the ACE INA debt securities and the ACE guarantee. You should refer to the ACE INA indentures and the ACE INA debt securities for complete information regarding the terms and provisions of the ACE INA indentures, the ACE INA debt securities and the ACE guarantee. The ACE INA indentures are substantially identical, except for the covenants of ACE INA and ACE and provisions relating to subordination.
 
General
 
The ACE INA indentures do not limit the aggregate principal amount of ACE INA debt securities which ACE INA may issue. ACE INA may issue ACE INA debt securities under the ACE INA indenture from time to time in one or more series. The ACE INA indentures do not limit the amount of other indebtedness or ACE INA debt securities, other than secured indebtedness which we, ACE INA or their respective subsidiaries may issue.
 
Unless otherwise set forth in the applicable prospectus supplement, the ACE INA senior debt securities will be unsecured obligations of ACE INA and will rank equally with all of its other unsecured and unsubordinated indebtedness, subordinated in right of payment to the prior payment in full of all of ACE INA’s senior indebtedness, which term includes ACE INA senior debt securities, as described below under “Subordination of ACE INA Subordinated Debt Securities.” The ACE INA subordinated debt securities of any series issued to an ACE Trust will rank equally with each other series of ACE INA subordinated debt securities issued to other ACE Trusts.
 
Because ACE INA is a holding company, its rights and the rights of its creditors, including you as a holder of ACE INA debt securities, to participate in any distribution of assets of any subsidiary upon that subsidiary’s liquidation or reorganization or otherwise would be subject to the prior claims of the subsidiary’s creditors, except to the extent that ACE INA is a creditor of the subsidiary. The rights of creditors of ACE INA, including you as a holder of ACE INA debt securities, to participate in the distribution of stock owned by ACE INA in its subsidiaries, including ACE INA’s insurance subsidiaries, may also be subject to the approval of insurance regulatory authorities having jurisdiction over the subsidiaries.
 
If ACE INA subordinated debt securities are issued to an ACE Trust in connection with the issuance of securities by that ACE Trust, those ACE INA subordinated debt securities may subsequently be distributed pro rata to the holders of the securities of the ACE Trust under the dissolution of that ACE Trust. This type of

ACE INA will have the ability under the ACE INA indentures to reopen a previously issued series of ACE INA debt securities and issue additional ACE INA debt securities of that series or establish additional terms of that series. ACE INA is also permitted to issue ACE INA debt securities with the same terms as previously issued ACE INA debt securities. (Section 3.1)
 
Unless otherwise set forth in the applicable prospectus supplement, principal of, premium and interest on and additional amounts, if any, on the ACE INA debt securities will initially be payable at the corporate trust

office of the trustee, or any other office or agency designated by ACE INA for this purpose. Interest on ACE INA debt securities issued in registered form:
 
 	•	 	may be paid by check mailed to the persons entitled to the payments at their addresses appearing on the security register or by transfer to an account maintained by the payee with a bank located in the United States; and	
 
 	•	 	will be payable on any interest payment date to the persons in whose names the ACE INA debt securities are registered at the close of business on the regular record date with respect to the interest payment date.	
 
ACE INA will designate the initial paying agents, which will be named in the applicable prospectus supplement, and may, at any time, designate additional paying agents or rescind the designation of any paying agent or approve a change in the office through which any paying agent acts. However, ACE INA is required to maintain a paying agent in each place where the principal of, any premium or interest on or any additional amounts with respect to the ACE INA debt securities are payable.
 
Unless otherwise set forth in the applicable prospectus supplement, you may present the ACE INA debt securities for transfer, duly endorsed or accompanied by a written instrument of transfer if so required by ACE INA or the security registrar, or exchange for other ACE INA debt securities of the same series containing identical terms and provisions, in any authorized denominations, and of a like aggregate principal amount, in each case at the office or agency maintained by ACE INA for these purposes. This office will initially be the corporate trust office of the trustee. Any transfer or exchange will be made without service charge, although ACE INA may require payment of a sum sufficient to cover any tax or other governmental charge and any other expenses then payable. ACE INA is not required to:
 
 	•	 	issue, register the transfer of, or exchange, ACE INA debt securities during a period beginning at the opening of business 15 days before the day of mailing of a notice of redemption of any ACE INA debt securities and ending at the close of business on the day of mailing; or	
 
 	•	 	register the transfer of or exchange any ACE INA debt security selected for redemption, in whole or in part, except the unredeemed portion of any ACE INA debt security being redeemed in part. (Section 3.5)	
 
ACE INA has appointed the trustee as security registrar. The security registrar and any transfer agent initially designated by ACE INA will be named in the applicable prospectus supplement. At any time, ACE INA may designate additional transfer agents or rescind the designation of any transfer agent or approve a change in the office through which any transfer agent acts. However, ACE INA is required to maintain a transfer agent in each place where the principal of, any premium or interest on or any additional amounts with respect to the ACE INA debt securities are payable. (Section 10.2)
 
Unless otherwise set forth in the applicable prospectus supplement, we will only issue the ACE INA debt securities in fully registered form without coupons in minimum denominations of $1,000 and any integral multiple of $1,000. (Section 3.2) If the ACE INA debt securities are issued in bearer form, any restrictions and considerations, including offering restrictions and U.S. Federal income tax considerations applicable to, and to payment on and transfer and exchange of, these securities, will be described in the applicable prospectus supplement.
 
The ACE INA debt securities may be issued as original issue discount securities, which means that they will bear no interest or bear interest at a rate which, at the time of issuance, is below market rates. ACE INA debt securities issued as original issue discount securities will be sold at a substantial discount below their principal amount. U.S. Federal income tax and other considerations applicable to original issue discount securities will be described in the applicable prospectus supplement.

If the purchase price, or the principal of, any premium or interest on or any additional amounts with respect to, any ACE INA debt securities is payable, or if any ACE INA debt securities are denominated, in one or more foreign currencies or currency units, the restrictions, elections, U.S. Federal income tax considerations, specific terms and other information will be set forth in the applicable prospectus supplement.
 
Unless otherwise set forth in the applicable prospectus supplement, other than as described below under “—Covenants Applicable to ACE INA Senior Debt Securities—Limitation on Liens on Stock of Designated Subsidiaries,” the ACE INA indentures do not contain any provisions that would limit the ability of ACE INA to incur indebtedness or that would afford holders of ACE INA debt securities protection in the event of a sudden and significant decline in the credit quality of ACE INA or ACE or a takeover, recapitalization or highly leveraged or similar transaction involving ACE INA or ACE. Accordingly, ACE INA or ACE could in the future enter into transactions that could increase the amount of its outstanding indebtedness that could affect its respective capital structure or credit rating.
 
ACE Guarantee
 
We will fully and unconditionally guarantee all payments on the ACE INA debt securities. Unless otherwise set forth in the applicable prospectus supplement, our guarantee of the ACE INA senior debt securities will be an unsecured obligation of ACE and will rank equally with all of its other unsecured and unsubordinated indebtedness. Our guarantee of the ACE INA subordinated debt securities will be an unsecured obligation of ACE, subordinated in right of payment to the prior payment in full of all ACE senior indebtedness. Our guarantee of the ACE INA subordinated debt securities issued to an ACE Trust will rank equally with our guarantee of each other series of ACE subordinated debt securities issued to other ACE Trusts.
 
Since we are a holding company, our rights and the rights of our creditors, including you as a holder of the ACE INA debt securities who would be a creditor of ours by virtue of our guarantee, and shareholders to participate in any distribution of the assets of any subsidiary upon the subsidiary’s liquidation or reorganization or otherwise would be subject to prior claims of the subsidiary’s creditors, except to the extent that we may be a creditor of the subsidiary. The right of our creditors, including you, to participate in the distribution of the stock owned by us in some of our subsidiaries, including our insurance subsidiaries, may also be subject to approval by insurance regulatory authorities having jurisdiction over the subsidiaries.
 
Conversion and Exchange
 
The terms, if any, on which ACE INA debt securities are convertible into or exchangeable for, either mandatorily, at your option or at ACE INA’s option, for ordinary shares of ACE, preferred shares of ACE or other securities, whether or not issued by ACE, property or cash, or a combination of any of these, will be set forth in the applicable prospectus supplement.
 
Payments of Additional Amounts
 
We will make all payments on ACE INA debt securities without withholding of any present or future taxes or governmental charges of the jurisdiction of ACE’s organization or principal executive offices (each, a “taxing jurisdiction”), unless we are required to do so by applicable law or regulation.
 
If under the laws or regulations of a taxing jurisdiction we are required to withhold amounts, we will, subject to the limitations described below, pay to you additional amounts so that every net payment made to you, after the withholding will not be the same amount provided for in the ACE INA debt security and the applicable ACE INA indenture.
 
38

Table of Contents
We will not be required to pay any additional amounts for
 
 	•	 	any tax or governmental charge which would not have been imposed but for the fact that you:	
 
 	•	 	were a resident of, or engaged in business or maintained a permanent establishment or were physically present in, the relevant taxing jurisdiction or otherwise had some connection with the relevant taxing jurisdiction other than the mere ownership of, or receipt of payment on, the ACE INA debt security,	
 
 	•	 	presented the ACE INA debt security for payment in the relevant taxing jurisdiction, unless the ACE debt security could not have been presented for payment elsewhere, or	
 
 	•	 	presented the ACE INA debt security for payment more than 30 days after the date on which the payment became due unless you would have been entitled to these additional amounts if you had presented the ACE debt security for payment within the 30-day period;	
 
 	•	 	any estate, inheritance, gift, sale, transfer, personal property or similar tax or other governmental charge;	
 
 	•	 	any tax or other governmental charge that is imposed or withheld because of your failure to comply with any reasonable request by us:	
 
 	•	 	to provide information concerning your nationality, residence or identity or that of the beneficial owner; or	
 
 	•	 	to make any claim or satisfy any information or reporting requirement, which in either case is required by the relevant taxing jurisdiction as a precondition to exemption from all or part of the tax or other governmental charge; or	
 
 	•	 	any combination of the above items.	
 
In addition, we will not pay additional amounts if you are a fiduciary or partnership or other than the sole beneficial owner of the ACE debt security if the beneficiary or partner or settlor would not have been entitled to the additional amounts had it been the holder of the ACE debt security. (Section 10.4)
 
Global Securities
 
The ACE INA debt securities may be issued, in whole or in part, in the form of one or more global securities that will be deposited with, or on behalf of, a depositary identified in the applicable prospectus supplement and registered in the name of the depositary or its nominee. Interests in any global ACE INA debt security will be shown on, and transfers of the ACE INA debt securities will be effected only through, records maintained by the depositary and its participants as described below.
 
The specific terms of the depositary arrangement will be described in the applicable prospectus supplement.
 
Option to Extend Interest Payment Date
 
If and as set forth in the applicable prospectus supplement, ACE INA will have the right, at any time and from time to time during the term of any series of ACE INA subordinated debt securities issued to an ACE Trust, to defer payment of interest for a number of consecutive interest payment periods, which we refer to in this prospectus supplement as an extension period. However, no extension period may extend beyond the stated maturity of the ACE INA subordinated debt securities. U.S. Federal income tax consequences and other considerations applicable to the ACE INA subordinated debt securities will be described in the applicable prospectus supplement. (Section 3.11 of the ACE INA subordinated indenture)

Covenants Applicable to ACE INA Senior Debt Securities
 
Limitation on Liens on Stock of Designated Subsidiaries
 
Under the ACE INA senior indenture, each of ACE INA and ACE will covenant that, so long as any ACE INA senior debt securities are outstanding, it will not, nor will it permit any subsidiary to create, incur, assume, guarantee or otherwise permit to exist any indebtedness secured by any security interest on any shares of capital stock of any designated subsidiary, unless ACE INA and ACE concurrently provide that the ACE INA senior debt securities and, if ACE INA and ACE elect, any other indebtedness of ACE INA that is not subordinate to the ACE INA senior debt securities and with respect to which the governing instruments require, or pursuant to which the ACE INA is otherwise obligated, to provide such security, will be secured equally with the indebtedness for at least the time period the other indebtedness is so secured. (Section 10.5 of the ACE INA senior indenture)
 
The term “designated subsidiary” means any present or future consolidated subsidiary of ACE, the consolidated net worth of which constitutes at least 5% of ACE’s consolidated net worth. (Section 1.1 of the ACE INA senior indenture).
 
For purposes of the ACE INA indentures, the term “indebtedness” means, with respect to any person:
 
 	•	 	the principal of and any premium and interest on:	
 
 	•	 	indebtedness for money borrowed and	
 
 	•	 	indebtedness evidenced by notes, debentures, bonds or other similar instruments for the payment of which the person is responsible or liable;	
 
 	•	 	all capitalized lease obligations;	
 
 	•	 	all obligations issued or assumed as the deferred purchase price of property, all conditional sale obligations and all obligations under any title retention agreement, but excluding trade accounts payable arising in the ordinary course of business;	
 
 	•	 	all obligations for the reimbursement of any obligor on any letter of credit, banker’s acceptance or similar credit transaction, generally other than obligations with respect to letters of credit securing obligations, other than obligations of the type referred to above, entered into in the ordinary course of business to the extent these letters of credit are not drawn upon or, if and to the extent drawn upon, such drawing is reimbursed no later than the third business day following receipt by such person of a demand for reimbursement following payment on the letter of credit;	
 
 	•	 	all obligations of the type referred to above of other persons and all dividends of other persons for the payment of which, in either case, the person is responsible or liable as obligor, guarantor or otherwise;	
 
 	•	 	all obligations of the type referred to above of other persons secured by any mortgage, pledge, lien, security interest or other encumbrance on any property or asset of the person, whether or not the obligation is assumed by the person; and	
 
 	•	 	any amendments, modifications, refundings, renewals or extensions of any indebtedness or obligation described above. (Section 1.1)	
 
Limitations on Disposition of Stock of Designated Subsidiaries
 
The ACE INA senior indenture also provides that, so long as any ACE INA senior debt securities are outstanding and except in a transaction otherwise governed by the ACE INA indentures, neither ACE INA nor ACE will issue, sell, assign, transfer or otherwise dispose of any shares of, securities convertible into, or
 
40

Table of Contents
warrants, rights or options to subscribe for or purchase shares of, capital stock, other than preferred stock having no voting rights, of any designated subsidiary. Similarly, ACE INA will not permit any designated subsidiary to issue, other than to ACE INA or ACE, these types of securities, warrants, rights or options, other than director’s qualifying shares and preferred stock having no voting rights, of any designated subsidiary, if, after giving effect to the transaction and the issuance of the maximum number of shares issuable upon the conversion or exercise of all the convertible securities, warrants, rights or options, ACE would own, directly or indirectly, less than 80% of the shares of capital stock of the designated subsidiary, other than preferred stock having no voting rights.
 
However, ACE INA may issue, sell, assign, transfer or otherwise dispose of securities if the consideration is at least a fair market value as determined by ACE INA’s board or if required by law or regulation. ACE INA or ACE, as the case may be, may also merge or consolidate any designated subsidiary into or with another direct or indirect subsidiary of ACE, the shares of capital stock of which ACE owns at least 80% or, subject to the provisions described under “—Consolidation, Amalgamation, Merger and Sale of Assets” below, sell, transfer or otherwise dispose of the entire capital stock of any designated subsidiary at one time if the consideration is at least fair market value as determined by ACE INA’s or ACE’s board. (Section 10.6 of the ACE INA senior indenture)
 
Covenants Applicable to ACE INA Subordinated Debt Securities Issued to an ACE Trust
 
Each of ACE INA and ACE will also covenant, as to each series of ACE INA subordinated debt securities issued to an ACE Trust in connection with the issuance of preferred securities and common securities by that ACE Trust, that it will not, and will not permit any of its subsidiaries to:
 
 	•	 	declare or pay any dividends or distributions on, or redeem, purchase, acquire or make a liquidation payment with respect to, any of the outstanding capital stock of ACE INA or ACE, as the case may be, or	
 
 	•	 	make any payment on or repay, repurchase or redeem any debt security of ACE INA or ACE that ranks junior in interest to the ACE INA subordinated debt securities or the related ACE guarantee, as the case may be, or make any payments with respect to any guarantee by ACE INA or ACE, as the case may be, of the debt securities of any subsidiary of ACE INA or ACE, as the case may be, if the guarantee ranks junior in interest to the ACE INA subordinated debt securities or the related ACE guarantee, as the case may be, other than:	
 
 	•	 	dividends or distributions on the capital stock of ACE INA paid or made to ACE and dividends or distributions in common stock of ACE INA or ordinary shares of ACE, as the case may be;	
 
 	•	 	redemptions or purchases of any rights outstanding under a shareholder rights plan of ACE INA or ACE, as the case may be, or the declaration of a dividend of these rights or the issuance of stock under the plans in the future;	
 
 	•	 	payments under any preferred securities guarantee; and	
 
 	•	 	purchases of common stock or ordinary shares related to the issuance of common stock or ordinary shares under any of ACE INA’s or ACE’s benefit plans for its directors, officers or employees	
 
if at that time:
 
 	•	 	any event of which ACE INA or ACE has actual knowledge that, with the giving of notice or lapse of time or both, would constitute an event of default and in respect of which ACE INA or ACE, as the case may be, shall not have taken reasonable steps to cure shall have occurred,	
 
41

Table of Contents

 	•	 	ACE shall be in default with respect to its payment of any obligations under the preferred securities guarantee relating to the related preferred securities or	
 
 	•	 	ACE INA shall have given notice of its election to begin an extension period and shall not have rescinded the notice, or the extension period, or any extension of the extension period, shall be continuing. (Section 10.9 of the ACE INA subordinated indenture)	
 
If ACE INA subordinated debt securities are issued to an ACE Trust in connection with the issuance of preferred securities and common securities of the ACE Trust, for so long as the ACE INA subordinated debt securities remain outstanding, ACE INA will also covenant:
 
 	•	 	to maintain, directly or indirectly, 100% ownership of the common securities of the ACE Trust;	
 
 	•	 	not to voluntarily dissolve, wind-up or liquidate the ACE Trust, except in connection with the distribution of ACE INA subordinated debt securities to the holders of preferred securities and common securities in liquidation of the ACE Trust, the redemption of all of the preferred securities and common securities of the ACE Trust or specified mergers, consolidations or amalgamations, each as permitted by the restated trust agreement of the ACE Trust, and	
 
 	•	 	to use its reasonable efforts, to cause the ACE Trust to remain classified as a grantor trust for U.S. Federal income tax purposes. (Section 10.9 of the ACE INA subordinated indenture)	
 
Consolidation, Amalgamation, Merger and Sale of Assets
 
Each ACE INA indenture provides that ACE INA and ACE may not:
 
 	•	 	consolidate or amalgamate with or merge into any person or convey, transfer or lease its properties and assets as an entirety or substantially as an entirety to any person, or	
 
 	•	 	permit any person to consolidate or amalgamate with or merge into ACE INA or ACE, respectively, or convey, transfer or lease its properties and assets as an entirety or substantially as an entirety to ACE INA or ACE, respectively,	
 
unless:
 
 	•	 	in the case of ACE INA, the person is a corporation organized and existing under the laws of the United States of America, any state of the United States or the District of Columbia;	
 
 	•	 	in the case of ACE, the person is a corporation organized and existing under the laws of the United States of America, any state of the U.S., the District of Columbia, Bermuda, the Cayman Islands or any other country that, on August 1, 1999, was a member of the Organization for Economic Cooperation and Development;	
 
 	•	 	the surviving entity expressly assumes, the payment of all amounts on all of the ACE INA or ACE debt securities and the performance of ACE INA’s or ACE’s obligations under the ACE INA indenture and the ACE INA debt securities or ACE indenture and ACE debt securities; and	
 
 	•	 	the surviving entity provides for conversion or exchange rights in accordance with the provisions of the ACE debt securities of any series that are convertible or exchangeable into ordinary shares or other securities; and	
 
 	•	 	immediately after giving effect to the transaction and treating any indebtedness which becomes an obligation of ACE INA or ACE or a subsidiary as a result of the transaction as having been incurred by ACE INA or ACE or the subsidiary at the time of the transaction, no event of default, and no event which after notice or lapse of time or both would become an event of default, will have happened and be continuing. (Sections 8.1 and 8.3)

Table of Contents
Events of Default
 
Each of the following events will constitute an event of default under each ACE INA indenture, whether it be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body:
 
 	•	 	default in the payment of any interest on, or any additional amounts payable with respect to, any ACE INA debt security when the interest or additional amounts become due and payable, and continuance of this default for a period of 30 days;	
 
 	•	 	default in the payment of the principal of or any premium on, or any additional amounts payable with respect to, any ACE INA debt security when the principal, premium or additional amounts become due and payable either at maturity, upon any redemption, by declaration of acceleration or otherwise;	
 
 	•	 	default in the deposit of any sinking fund payment, when due;	
 
 	•	 	default in the performance, or breach, of any covenant or warranty of ACE INA or ACE for the benefit of the holders of the ACE INA debt securities, and the continuance of this default or breach for a period of 60 days after ACE INA has received written notice from the holders;	
 
 	•	 	if any event of default under a mortgage, indenture or instrument under which ACE or ACE INA may issue, or by which ACE or ACE INA may secure or evidence, any indebtedness, including an event of default under any other series of ACE INA debt securities, whether the indebtedness now exists or is later created or incurred, happens and consists of default in the payment of more than $50,000,000 in principal amount of indebtedness at the maturity of the indebtedness, after giving effect to any applicable grace period, or results in the indebtedness in principal amount in excess of $50,000,000 becoming or being declared due and payable prior to the date on which it would otherwise become due and payable, and this default is not cured or the acceleration is not rescinded or annulled within a period of 30 days after ACE INA has received written notice;	
 
 	•	 	ACE INA or ACE shall fail within 60 days to pay, bond or otherwise discharge any uninsured judgment or court order for the payment of money in excess of $50,000,000, which is not stayed on appeal or is not otherwise being appropriately contested in good faith;	
 
 	•	 	events in bankruptcy, insolvency or reorganization of ACE INA or ACE; and	
 
 	•	 	any other event of default, which will be described in the applicable prospectus supplement. (Section 5.1)	
 
If an event of default with respect to the ACE INA debt securities of any series, other than events of bankruptcy, insolvency or reorganization, occurs and is continuing, either the trustee or the holders of not less than 25% in principal amount of the outstanding ACE INA debt securities of the series may declare the principal amount, or a lesser amount as may be provided for in the ACE INA debt securities, of all outstanding ACE INA debt securities of the series to be immediately due and payable by written notice. In the case of an event of default with respect to a series of ACE INA subordinated debt securities issued to an ACE Trust, if the trustee or the holders fail to declare the principal amount, or lesser amount, to be due and payable immediately, the holders of at least 25% in liquidation amount of the outstanding preferred securities of the ACE Trust may do so by written notice. At any time after a declaration of acceleration has been made, but before a judgment or decree for payment of money has been obtained by the trustee, generally, the holders of not less than a majority in principal amount of the ACE INA debt securities of the series may rescind and annul the declaration of acceleration. In the case of a series of ACE INA subordinated debt securities issued to an ACE Trust, if the holders fail to rescind and annul the declaration, the holders of a majority in liquidation amount of the outstanding preferred securities of the ACE Trust may, subject to satisfaction of specified conditions, rescind and annul the declaration by written

notice. Any event of bankruptcy, insolvency or reorganization will cause the principal amount and accrued interest, or the lesser amount as provided for in the ACE INA debt securities, to become immediately due and payable without any declaration or other act by the trustee or any holder. (Section 5.2)
 
Each ACE INA indenture provides that, within 90 days after the occurrence of any event which is, or after notice or lapse of time or both would become, an event of default the trustee must transmit, notice of the default to each holder of the ACE INA debt securities unless the default has been cured or waived. However, except in the case of a default in the payment of principal of, or premium or interest, if any, on or additional amounts or any sinking fund or purchase fund installment with respect to any ACE INA debt security, the trustee may withhold this notice if and so long as the board of directors, executive committee or trust committee of directors and/or responsible officers of the trustee determine in good faith that the withholding of the notice is in the best interest of the holders. (Section 6.2)
 
If an event of default occurs and is continuing with respect to the ACE INA debt securities of any series, the trustee may, in its discretion, proceed to protect and enforce its rights and the rights of the holders of ACE INA debt securities by all appropriate judicial proceedings. (Section 5.3) Each ACE INA indenture provides that, subject to the duty of the trustee during any default to act with the required standard of care, the trustee will be under no obligation to exercise any of its rights or powers under the ACE INA indenture at the request or direction of any of the holders, unless the holders have offered the trustee reasonable indemnity. (Section 6.1) Subject to these indemnification provisions, the holders of a majority in principal amount of the outstanding ACE INA debt securities of any series will generally have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred on the trustee, with respect to the ACE INA debt securities of the series. (Section 5.12)
 
If an event of default with respect to a series of ACE INA subordinated debt securities issued to an ACE Trust has occurred and is continuing and this event is attributable to a default in the payment of principal of, any premium or interest on or additional amounts with respect to the related ACE INA subordinated debt securities on the date the principal, premium, interest or additional amounts are otherwise payable, a holder of preferred securities of the ACE Trust may institute directly a legal proceeding against ACE INA or ACE, pursuant to the ACE guarantee, for enforcement of payment to the holder of the principal of, any premium and interest on and additional amounts with respect to the related ACE INA subordinated debt securities having a principal amount equal to the liquidation amount of the holder’s related preferred securities, referred to in this prospectus as a direct action. (Section 5.8 of the ACE INA subordinated indenture) ACE INA and ACE may not amend the ACE INA subordinated indenture to remove this right to bring a direct action without the prior consent of the holders of all of the outstanding preferred securities of the ACE Trust. (Section 9.2 of the ACE INA subordinated indenture) If the right to bring a direct action is removed, the applicable ACE Trust may become subject to the reporting obligations under the Exchange Act. Each of ACE INA and ACE will have the right under the ACE INA subordinated indenture to set-off any payment made to a holder of preferred securities by ACE INA or ACE, as the case may be, in connection with a direct action. (Section 3.12 of the ACE INA subordinated indenture)
 
The holders of the preferred securities will not be able to exercise directly any remedies other than those set forth in the preceding paragraph available to the holders of the related ACE INA subordinated debt securities.

The holders of at least a majority in principal amount of the outstanding ACE INA debt securities of any series may, on behalf of the holders of all ACE INA debt securities of that series, waive compliance by ACE INA and ACE with specified covenants of the applicable ACE INA indenture. (Section 10.8 of the ACE INA senior indenture; Section 10.6 of the ACE INA subordinated indenture) The holders of not less than a majority in principal amount of the outstanding ACE INA debt securities on behalf of the holders of all ACE INA debt securities of that series and, in the case of any ACE INA subordinated debt securities issued to an ACE Trust, the holders of not less than a majority in liquidation amount of the outstanding preferred securities of the ACE Trust, may waive any past default and its consequences with respect to the ACE INA debt securities of that series, except a default:

Discharge, Defeasance and Covenant Defeasance
 
ACE INA or ACE may discharge their payment obligations on the ACE INA debt securities, which we refer to as defeasance, or elect to be discharged from complying with the covenants in the ACE NA indentures, except for certain ministerial obligations, like registering transfers or exchanges of the ACE INA debt securities, which we refer to as covenant defeasance.
 
ACE INA or ACE may only do this if, among other things,
 
 	•	 	the defeasance or covenant defeasance does not result in a breach or violation of, or constitute a default under, the applicable ACE INA indenture or any other material agreement or instrument to which ACE INA or ACE is a party or by which either or them is bound,	
 
 	•	 	no event of default or event which with notice or lapse of time or both would become an event of default with respect to the ACE INA debt securities to be defeased will have occurred and be continuing on the date of establishment of the trust and, with respect to defeasance only, at any time during the period ending on the 123rd day after that date and	
 
 	•	 	ACE INA or ACE has delivered to the trustee an opinion of counsel to the effect that the you will not recognize income, gain or loss for U.S. Federal income tax purposes as a result of the defeasance or covenant defeasance and will be subject to U.S. Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if the defeasance or covenant defeasance had not occurred. The opinion of counsel, in the case of defeasance, must refer to and be based upon a letter ruling of the I.R.S. received by ACE, a Revenue Ruling published by the I.R.S. or a change in applicable U.S. Federal income tax law occurring after the date of the applicable ACE indenture. (Section 4.2)	
 
Subordination of ACE INA Subordinated Debt Securities
 
The ACE INA subordinated debt securities will generally be subordinate in right of payment to the prior payment in full of all senior indebtedness. (Section 16.1 of the ACE INA subordinated indenture) Upon any payment or distribution of assets of ACE INA of any kind or character, whether in cash, property or securities, to creditors upon any dissolution, winding-up, liquidation or reorganization of ACE INA, whether voluntary or involuntary, or in bankruptcy, insolvency, receivership or other proceedings, all amounts due upon all senior indebtedness will first be paid in full, or payment provided for in money in accordance with its terms, before the holders of ACE INA subordinated debt securities of that series are entitled to receive or retain any payment on account of principal of, or any premium or interest on, or any additional amounts with respect to, the ACE INA subordinated debt securities. This means that the holders of the senior indebtedness will be entitled to receive any payment or distribution, which may be payable or deliverable by reason of the payment of any other indebtedness of ACE INA being subordinated to the payment of ACE INA subordinated debt securities, which may be payable or deliverable in respect of the ACE INA subordinated debt securities upon any dissolution, winding-up, liquidation or reorganization or in any bankruptcy, insolvency, receivership or other proceeding. (Section 16.3 of the ACE INA subordinated indenture)
 
By reason of this subordination, in the event of liquidation or insolvency of ACE INA, holders of senior indebtedness and holders of other obligations of ACE INA that are not subordinated to the senior indebtedness may recover more, ratably, than the holders of the ACE INA subordinated debt securities.

Table of Contents
Subject to the payment in full of all senior indebtedness, the rights of the holders of the ACE INA subordinated debt securities will be subrogated to the rights of the holders of the senior indebtedness to receive payments or distributions of cash, property or securities of ACE INA applicable to the senior indebtedness until the principal of, any premium and interest on, and any additional amounts with respect to, the ACE INA subordinated debt securities have been paid in full. (Section 16.4 of the ACE INA subordinated indenture)
 
No payment of principal of, including redemption and sinking fund payments, or any premium or interest on or any additional amounts with respect to the ACE INA subordinated debt securities may be made by ACE INA if:
 
 	•	 	any senior indebtedness is not paid when due, any applicable grace period with respect to the default has ended and the default has not been cured or waived or ceased to exist, or	
 
 	•	 	the maturity of any senior indebtedness has been accelerated because of a default. (Section 16.2 of the ACE INA subordinated indenture)	
 
The ACE INA subordinated indenture does not limit or prohibit ACE INA from incurring additional senior indebtedness, which may include indebtedness that is senior to the ACE INA subordinated debt securities, but subordinate to other obligations of ACE INA. The ACE INA senior debt securities will constitute senior indebtedness with respect to the ACE INA subordinated debt securities.
 
The term “senior indebtedness” means, with respect to the ACE INA subordinated debt securities of any particular series, all indebtedness of ACE INA outstanding at any time, except:
 
 	•	 	the ACE INA subordinated debt securities of that series;	
 
 	•	 	indebtedness as to which, by the terms of the instrument creating or evidencing the same, it is provided that the indebtedness is subordinated to or ranks equally with the ACE INA subordinated debt securities;	
 
 	•	 	indebtedness of ACE INA to an affiliate of ACE INA;	
 
 	•	 	interest accruing after the filing of a petition initiating any bankruptcy, insolvency or other similar proceeding unless the interest is an allowed claim enforceable against ACE INA in a proceeding under federal or state bankruptcy laws;	
 
 	•	 	trade accounts payable; and	
 
 	•	 	any indebtedness, including all other debt securities and guarantees in respect of those debt securities, initially issued to:	
 
 	•	 	any ACE Trust or	
 
 	•	 	any trust, partnership or other entity affiliated with ACE which is a financing vehicle of ACE or any affiliate of ACE in connection with an issuance by the entity of preferred securities or other securities which are similar to the preferred securities described under “Description of Preferred Securities” below that are guaranteed by ACE pursuant to an instrument that ranks equally with or junior in right of payment to the preferred securities guarantees described under “Description of the Preferred Securities Guarantees” below.	
 
Senior indebtedness with respect to the ACE INA subordinated debt securities shall continue to be entitled to the benefits of the subordination provisions irrespective of any amendment, modification or waiver of any term of the senior indebtedness. (Sections 1.1 and 16.8 of the ACE INA subordinated indenture)

The ACE INA subordinated indenture provides that the subordination provisions, insofar as they relate to any particular series of ACE INA subordinated debt securities, may be changed prior to issuance of the applicable ACE INA subordinated debt securities, which change would be described in the applicable prospectus supplement.
 
Subordination of ACE Guarantee of ACE INA Subordinated Debt Securities
 
The ACE guarantee of ACE INA subordinated debt securities will generally be subordinate in right of payment to the prior payment in full of all ACE senior indebtedness. (Section 18.1 of the ACE INA subordinated indenture) Upon any payment or distribution of assets of ACE of any kind or character, whether in cash, property or securities, to creditors upon any dissolution, winding-up, liquidation or reorganization of ACE, whether voluntary or involuntary, or in bankruptcy, insolvency, receivership or other proceedings, all amounts due upon all ACE senior indebtedness will first be paid in full, or payment of the ACE senior indebtedness provided for in money in accordance with its terms, before the holders of ACE INA subordinated debt securities are entitled to receive or retain any payment from ACE on account of principal of, or any premium or interest on, or any additional amounts with respect to, the ACE INA subordinated debt securities. This means that the holders of ACE senior indebtedness shall be entitled to receive any payment or distribution by ACE of any kind or character, including any payment or distribution which may be payable or deliverable by ACE by reason of the payment of any other indebtedness of ACE being subordinated to the payment of ACE INA subordinated debt securities, which may be payable or deliverable by ACE in respect of the ACE INA subordinated debt securities upon any dissolution, winding-up, liquidation or reorganization or in any bankruptcy, insolvency, receivership or other proceeding. (Section 18.3 of the ACE INA subordinated indenture)
 
By reason of this subordination, in the event of liquidation or insolvency of ACE, holders of ACE senior indebtedness and holders of other obligations of ACE that are not subordinated to the ACE senior indebtedness may recover more, ratably, than the holders of the ACE INA subordinated debt securities.
 
Subject to the payment in full of all ACE senior indebtedness, the rights of the holders of the ACE INA subordinated debt securities under the ACE guarantee will be subrogated to the rights of the holders of the ACE senior indebtedness to receive payments or distributions of cash, property or securities of ACE applicable to the ACE senior indebtedness until the principal of, any premium and interest on, and any additional amounts with respect to, the ACE INA senior debt securities have been paid in full. (Section 18.4 of the ACE INA subordinated indenture)
 
No payment of principal of, including redemption and sinking fund payments, or any premium or interest on or any additional amounts with respect to the ACE INA subordinated debt securities of any series may be made by ACE if:

 	•	 	the maturity of any ACE senior indebtedness has been accelerated because of a default. (Section 18.2 of the ACE INA subordinated indenture)	
 
The ACE INA subordinated indenture does not limit or prohibit ACE from incurring additional ACE senior indebtedness, which may include indebtedness that is senior to the ACE guarantee of the ACE INA subordinated debt securities, but subordinate to other obligations of ACE. The ACE senior debt securities will constitute ACE senior indebtedness with respect to the ACE INA subordinated debt securities.

 DESCRIPTION OF PREFERRED SECURITIES
 
Each ACE Trust will be governed by an amended and restated trust agreement, which refer to in this prospectus as a trust agreement, a form of which is an exhibit to the registration statement of which this prospectus forms a part. Under each trust agreement, the ACE Trust may issue, from time to time, only one series of preferred securities with the terms set forth in the trust agreement or made a part of the trust agreement by the Trust Indenture Act, which terms we will set forth in the applicable prospectus supplement. The terms of the ACE Trust preferred securities will generally mirror the terms of the ACE INA subordinated debt securities, which the ACE Trust will purchase with the proceeds from the sale of its preferred securities and its common securities. The ACE INA subordinated debt securities issued to an ACE Trust will be guaranteed by ACE on a subordinated basis and are referred to in this prospectus as the corresponding ACE INA subordinated debt securities relating to that ACE Trust.
 
The following is a summary of the material terms and provisions of each trust agreement and the preferred securities. You should refer to the form of amended and restated trust agreement and to the Trust Indenture Act for complete information regarding the terms and provisions of the trust agreement and of the preferred securities.
 
Issuance, Status and Guarantee of Preferred Securities
 
The preferred securities will represent preferred beneficial interests in an ACE Trust and you, as holders of the preferred securities, will be entitled to a preference in specified circumstances, including as regards distributions and amounts payable on redemption or liquidation over the common securities of the applicable ACE Trust. The preferred securities of each ACE Trust will rank equally, and payments will be made on the preferred securities pro rata , with the common securities of that ACE Trust, except as described under “—Subordination of Common Securities” below. The property trustee will hold legal title to the corresponding ACE INA subordinated debt securities in trust for your benefit and for the benefit of the holder of the ACE Trust’s common securities. In this prospectus, we refer to the common securities and the preferred securities of an ACE Trust collectively as the “trust securities” of that ACE Trust.
 
ACE will guarantee, which we refer to in this prospectus as the preferred securities guarantee, the preferred securities. Under each preferred securities guarantee, ACE will guarantee, on a subordinated basis, payment of distributions on the related preferred securities and amounts payable on redemption or liquidation of the related preferred securities, but only to the extent that the related ACE Trust has funds to make these payments. See “Description of Preferred Securities Guarantees.”
 
Distributions
 
Distributions on the preferred securities will accumulate from the original issue date and will be payable on the dates specified in the applicable prospectus supplement. If any date on which these distributions are payable is not a business day, payment of the distribution payable on that date will be made on the next succeeding business day without any additional distributions or other payment in respect of the delay. However, if the next succeeding business day is in the next succeeding calendar year, payment of the distribution will be made on the immediately preceding business day, in each case as if made on the date the payment was originally payable. We refer to each date on which distributions are payable in this prospectus as a distribution date. (Section 4.1) A “business day” is any day other than a Saturday or a Sunday, or a day on which banking institutions in The City of New York are authorized or required by law or executive order to remain closed or a day on which the corporate trust office of the property trustee or the trustee for the corresponding ACE INA subordinated debt securities is closed for business. (Section 1.1)
 
Distributions on each preferred security will be payable at the rate specified in the applicable prospectus supplement and the amount of distributions payable for any period will be computed on the basis of a 360-day

year of twelve 30-day months unless otherwise specified in the applicable prospectus supplement. Distributions to which you are entitled will accumulate additional distributions at the rate per annum if and as specified in the applicable prospectus supplement. References to “distributions” include any accumulated or additional distributions unless otherwise stated. (Section 4.1)
 
If set forth in the applicable prospectus supplement, ACE INA will have the right under the ACE INA subordinated indenture to defer the payment of interest on any series of corresponding ACE INA subordinated debt securities for the period specified in the applicable prospectus supplement. However, no extension period may extend beyond the stated maturity of the corresponding ACE INA subordinated debt securities. See “Description of ACE INA Debt Securities and ACE Guarantee—Option to Extend Interest Payment Date.” As a consequence of any extension, distributions on the corresponding preferred securities would be deferred but would continue to accumulate additional distributions at the rate set forth in the applicable prospectus supplement, which rate will match the interest rate payable on the corresponding ACE INA subordinated debt securities during the extension period, by the ACE Trust which issued the preferred securities during any extension period. (Section 4.1)
 
The funds of each ACE Trust available for distribution to you will be limited to payments under the corresponding ACE INA subordinated debt securities in which the ACE Trust will invest the proceeds from the issuance and sale of its trust securities. If ACE INA or ACE, as the case may be, does not make interest payments on those corresponding ACE INA subordinated debt securities, the property trustee will not have funds available to pay distributions on the related preferred securities. The payment of distributions, if and to the extent the ACE Trust has funds legally available for the payment of the distributions and cash sufficient to make the payments, is guaranteed by ACE as set forth under “Description of Preferred Securities Guarantees.”
 
Distributions on the preferred securities will be payable to the holders of the preferred securities as they appear on the register of the applicable ACE Trust on the relevant record dates. As long as the preferred securities remain in book-entry form, the record dates will be one business day prior to the relevant distribution dates. Generally, each distribution payment will be made as described under “Global Preferred Securities.” If any preferred securities are not in book-entry form, the relevant record date will be the date at least 15 days prior to the relevant distribution date, as specified in the applicable prospectus supplement. (Section 4.1)
 
Redemption or Exchange
 
Mandatory Redemption. Upon any repayment or redemption, in whole or in part, of any corresponding ACE INA subordinated debt securities held by an ACE Trust, the property trustee will simultaneously apply the proceeds from the repayment or redemption, upon not less than 30 nor more than 60 days notice to holders of trust securities, to redeem, on a pro rata basis, trust securities having an aggregate stated liquidation amount equal to the aggregate principal amount of the corresponding ACE INA subordinated debt securities repaid or redeemed. The redemption price per trust security will be equal to its stated liquidation amount, plus any accumulated and unpaid distributions on the trust security to the redemption date, plus the related amount of premium, if any, and any additional amounts paid by ACE INA or ACE upon the concurrent repayment or redemption of the corresponding ACE INA subordinated debt securities. The amount described in the preceding sentence is referred to in this prospectus as the redemption price. (Section 4.2) If less than all of the corresponding ACE INA subordinated debt securities are to be repaid or redeemed on a redemption date, then the property trustee shall allocate the proceeds from the repayment or redemption to the redemption pro rata of the related trust securities. (Section 4.2)
 
Generally, ACE INA will have the right to redeem any series of corresponding ACE INA subordinated debt securities at any time, in whole but not in part, upon the occurrence of a special event and subject to the conditions described under “Description of ACE INA Debt Securities and ACE Guarantee—Redemption.”

Table of Contents
Special Event Redemption or Distribution of Corresponding ACE INA Subordinated Debt Securities. If a special event relating to the trust securities of an ACE Trust occurs and is continuing, within 90 days following the occurrence of the special event, ACE INA has the right to redeem the corresponding ACE INA subordinated debt securities, in whole but not in part, and, in doing so, cause a mandatory redemption of the related trust securities, in whole but not in part, at the redemption price. At any time, ACE INA has the right to dissolve the ACE Trust and, after satisfaction of the liabilities of creditors of the ACE Trust, cause the corresponding ACE INA subordinated debt securities to be distributed to the holders of the trust securities in liquidation of the ACE Trust. If ACE INA does not elect to redeem the corresponding ACE INA subordinated debt securities upon the occurrence of a special event, the applicable trust securities will remain outstanding. If a tax event has occurred and is continuing, additional sums may be payable on the corresponding ACE INA subordinated debt securities. For purposes of this section, “additional sums” means the additional amounts as may be necessary in order that the amount of distributions then due and payable by an ACE Trust on its outstanding trust securities shall not be reduced as a result of any additional taxes, duties and other governmental charges to which it has become subject as a result of a tax event. (Section 1.1)
 
On and from the date fixed for any distribution of corresponding ACE INA subordinated debt securities upon dissolution of an ACE Trust:
 
 	•	 	the trust securities will no longer be deemed to be outstanding;	
 
 	•	 	the depositary or its nominee, as the record holder of the related preferred securities, will receive a registered global certificate or certificates representing the corresponding ACE INA subordinated debt securities to be delivered upon the distribution, upon surrender of the related preferred securities certificates for exchange; and	
 
 	•	 	any certificates representing the preferred securities, which is not surrendered for exchange will be deemed to represent beneficial interests in the corresponding ACE INA subordinated debt securities having an aggregate principal amount equal to the aggregate stated liquidation amount of the preferred securities and accruing interest at the rate provided for in the debt securities, which rate will equal the distribution rate on the preferred securities, until the certificates are presented to the administrative trustees or their agent for exchange. (Section 9.4)	
 
There can be no assurance as to the market prices for the preferred securities or the corresponding ACE INA subordinated debt securities that may be distributed in exchange for preferred securities if a dissolution and liquidation of an ACE Trust were to occur. Accordingly, the preferred securities that you may purchase, and the corresponding ACE INA subordinated debt securities that you may receive on dissolution and liquidation of an ACE Trust, may trade at a discount to the price that you paid to purchase the preferred securities.
 
Redemption Procedures
 
The property trustee shall redeem the preferred securities on each redemption date at the redemption price with the applicable proceeds from the contemporaneous redemption of the corresponding ACE INA subordinated debt securities. The property trustee will redeem the preferred securities, and shall pay the redemption price, on each redemption date only to the extent that the applicable ACE Trust has funds on hand available for the payment of the redemption price. See also “—Subordination of Common Securities.”
 
If an ACE Trust gives a notice of redemption, which notice will be irrevocable, in respect of its preferred securities, then, by 12:00 noon, New York City time, on the redemption date, to the extent funds are available,
 
56

Table of Contents
the property trustee will deposit irrevocably with the depositary for the preferred securities funds sufficient to pay the applicable redemption price. The property trustee will also give the depositary irrevocable instructions and authority to pay the redemption price to you, as a holder of the preferred securities. If the preferred securities are no longer in book-entry form, the property trustee, to the extent funds are available, will irrevocably deposit with the paying agent for the preferred securities funds sufficient to pay the applicable redemption price and will give the paying agent irrevocable instructions and authority to pay the redemption price to you upon surrender of your certificates evidencing the preferred securities. Notwithstanding the preceding sentences, distributions payable on or prior to the redemption date for any preferred securities called for redemption shall be payable to you on the relevant record date for the related distribution dates. If notice of redemption shall have been given and funds deposited as required, then, immediately prior to the close of business on the date of the deposit, all of your rights, as a holder of preferred securities so called for redemption, will cease, except your right to receive the redemption price, but without interest, and your preferred securities will cease to be outstanding. If any date on which any redemption price is payable is not a business day, then payment of the redemption price payable on that date will be made on the next succeeding business day without any interest or other payment in respect of the delay. However, if the next succeeding business day falls in the next calendar year, the payment will be made on the immediately preceding business day, in each case with the same force and effect as if made on the proper payment date. If that payment of the redemption price is improperly withheld or refused and not paid either by the ACE Trust or by ACE pursuant to the preferred securities guarantee as described under “Description of Preferred Securities Guarantees,” distributions on the preferred securities will continue to accumulate interest at the then applicable rate, from the redemption date originally established by the ACE Trust for the preferred securities to the date the redemption price is actually paid, in which case the actual payment date will be the date fixed for redemption for purposes of calculating the redemption price.
 
Generally, ACE or its subsidiaries, including ACE INA, may purchase outstanding preferred securities.
 
Payment of the redemption price on the preferred securities will be made to the record holders as they appear on the register for the preferred securities on the relevant record date, which will be one business day prior to the relevant redemption date. If any preferred securities are not in book-entry form, the relevant record date for the preferred securities will be a date at least 15 days prior to the redemption date, as specified in the applicable prospectus supplement.
 
The property trustee will allocate the aggregate liquidation amount pro rata to the trust securities based upon the relative liquidation amounts of the classes if less than all of the trust securities issued by an ACE Trust are to be redeemed on a redemption date. The property trustee will select on a pro rata basis not more than 60 days prior to the redemption date from the outstanding preferred securities not previously called for redemption the particular preferred securities to be redeemed by any method, including without limitation by lot, as it shall deem fair and appropriate. The property trustee will promptly notify the trust registrar in writing of the preferred securities selected for redemption and, in the case of any preferred securities selected for partial redemption, the liquidation amount of the preferred securities to be redeemed. Generally, for purposes of each trust agreement, all provisions relating to the redemption of preferred securities will relate, in the case of any preferred securities redeemed or to be redeemed only in part, to the portion of the liquidation amount of preferred securities which has been or is to be redeemed.
 
Notice of any redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each holder of trust securities to be redeemed at its registered address. Unless each of ACE INA and ACE defaults in payment of the redemption price on the corresponding ACE INA subordinated debt securities, on and after the redemption date interest will cease to accrue on the ACE INA subordinated debt securities or portions of the ACE INA subordinated debt securities, and distributions will cease to accrue on the related preferred securities or portions of the related preferred securities, called for redemption. (Section 4.2)

Subordination of Common Securities
 
Payment on each ACE Trust’s trust securities will be made pro rata based on the liquidation amount of the trust securities. However, if an event of default under the corresponding ACE INA subordinated debt securities occurs and is continuing on any distribution date or redemption date, no payment of any distribution on, or redemption price of, any of the ACE Trust’s common securities, and no other payment on account of the redemption, liquidation or other acquisition of the common securities, will be made unless payment in full in cash of all accumulated and unpaid distributions on all of the ACE Trust’s outstanding preferred securities for all distribution periods terminating on or prior to that date, or in the case of payment of the redemption price the full amount of the redemption price on all of the ACE Trust’s outstanding preferred securities then called for redemption, have been made or provided for, and all funds available to the property trustee will first be applied to the payment in full in cash of all distributions on, or redemption price of, the ACE Trust’s preferred securities then due and payable.
 
If any event of default under the trust agreement resulting from a event of default under the corresponding ACE INA subordinated debt securities occurs, the holder of the ACE Trust’s common securities will be deemed to have waived any right to act with respect to that event of default until the effect of all of the events of default with respect to the preferred securities have been cured, waived or otherwise eliminated. Until these events of default have been so cured, waived or otherwise eliminated, the property trustee shall act solely on behalf of the holders of the preferred securities and not on behalf of the holder of the ACE Trust’s common securities, and only the holders of the preferred securities will have the right to direct the property trustee to act on their behalf. (Section 4.3)
 
Liquidation Distribution Upon Dissolution of ACE Trust
 
Pursuant to each trust agreement, each ACE Trust will automatically dissolve upon expiration of its term and will dissolve on the first to occur of:
 
 	•	 	bankruptcy, dissolution or liquidation of ACE INA or ACE;	
 
 	•	 	the written direction to the property trustee from ACE INA, as depositor, at any time, which direction is optional and wholly within the discretion of ACE INA, to dissolve the ACE Trust and distribute corresponding ACE INA subordinated debt securities having an aggregate principal amount equal to the aggregate stated liquidation amount of the trust securities to the holders of the trust securities in exchange for the trust securities;	
 
 	•	 	the redemption of all of the ACE Trust’s trust securities following a special event;	
 
 	•	 	the redemption of all of the ACE Trust’s preferred securities as described under “Description of Preferred Securities—Redemption or Exchange—Mandatory Redemption”; and	
 
 	•	 	the entry of an order for the dissolution of the ACE Trust by a court of competent jurisdiction. (Section 9.2)	
 
If an early dissolution occurs as described in the first, second and fifth bullets above or upon the date designated for automatic dissolution of the ACE Trust, the ACE Trust will be liquidated by the ACE trustees as expeditiously as the ACE trustees determine to be possible by distributing to the holders of the trust securities, after satisfaction of liabilities to the ACE Trust’s creditors, corresponding ACE INA subordinated debt securities having an aggregate principal amount equal to the aggregate stated liquidation amount of the trust securities. However, if the property trustee determines that this distribution is not practical, the holders will be entitled to receive out of the ACE Trust’s assets available for distribution, after satisfaction of liabilities to the ACE Trust’s

Table of Contents
creditors, an amount equal to, in the case of holders of preferred securities, the aggregate of the liquidation amount plus accumulated and unpaid distributions on the trust securities to the date of payment, this amount being referred to in this prospectus as the liquidation distribution. If the liquidation distribution can be paid only in part because the ACE Trust has insufficient assets available to pay in full the aggregate liquidation distribution, then the amounts payable directly by the ACE Trust on its preferred securities will be paid on a pro rata basis. The holder of the ACE Trust’s common securities will be entitled to receive distributions upon any liquidation pro rata with the holders of its preferred securities, except that if an event of default under the corresponding ACE INA subordinated debt securities has occurred and is continuing, the preferred securities shall have a priority over the common securities. (Section 9.4)
 
Events of Default; Notice
 
The following constitute an event of default under each trust agreement with respect to the applicable preferred securities:
 
 	•	 	the occurrence of an event of default on the corresponding ACE INA subordinated debt securities (see “Description of ACE INA Debt Securities and ACE Guarantee—Events of Default”);	
 
 	•	 	default by the property trustee in the payment of any distribution when it becomes due and payable, and continuation of this default for a period of 30 days;	
 
 	•	 	default by the property trustee in the payment of any redemption price of any trust security when it becomes due and payable;	
 
 	•	 	default in the performance, or breach, in any material respect, of any covenant or warranty of the ACE trustees in the trust agreement, other than a covenant or warranty a default in the performance or breach those covenants in the preceding two bullets, and continuation of the default or breach for a period of 60 days after the holders of at least 25% in aggregate liquidation preference of the outstanding preferred securities of the applicable ACE Trust have given written notice specifying the default or breach, requiring it to be remedied and stating that the notice is a “Notice of Default” under the trust agreement, by registered or certified mail to the defaulting ACE trustee(s); and	
 
 	•	 	the occurrence of specified events of bankruptcy or insolvency with respect to the property trustee and the failure by ACE INA, as depositor, to appoint a successor property trustee within 60 days of the occurrence. (Section 1.1)	
 
Within five business days after the occurrence of any event of default actually known to the property trustee, the property trustee will transmit notice of the event of default to the holders of the applicable preferred securities, the administrative trustees and ACE INA, as depositor, unless the event of default has been cured or waived. (Section 8.2) ACE INA, as depositor, and the administrative trustees are required to file annually with the property trustee a certificate as to whether or not they are in compliance with all the conditions and covenants applicable to them under each trust agreement. (Sections 8.15 and 8.16)
 
If an event of default under the corresponding ACE INA subordinated debt securities has occurred and is continuing, the preferred securities shall have a preference over the common securities upon dissolution of each ACE Trust as described above. See “—Liquidation Distribution Upon Dissolution of ACE Trust.” The existence of an event of default under the trust agreement does not entitle the holders of preferred securities to accelerate the maturity of the preferred securities.

Removal of ACE Trustees
 
Unless an event of default under the corresponding ACE INA subordinated debt securities has occurred and is continuing, any ACE trustee may be removed at any time by the holder of the ACE Trust’s common securities. If an event of default under the corresponding ACE INA subordinated debt securities has occurred and is continuing, the property trustee and the Delaware trustee may be removed by the holders of a majority in liquidation amount of the outstanding preferred securities. In no event will the holders of the preferred securities have the right to vote to appoint, remove or replace the administrative trustees, which voting rights are vested exclusively in the holder of the ACE Trust’s common securities. No resignation or removal of an ACE trustee and no appointment of a successor trustee shall be effective until the acceptance of appointment by the successor trustee in accordance with the provisions of the applicable trust agreement. (Section 8.10)
 
Co-Trustees and Separate Property Trustee
 
Unless an event of default shall have occurred and be continuing, for the purpose of meeting the legal requirements of the Trust Indenture Act or of any jurisdiction in which any part of the property of any ACE Trust may at the time be located, ACE INA, as depositor, and the administrative trustees shall have power, at any time or times, to appoint one or more persons either to act as a co-trustee jointly with the property trustee of all or any part of the property of the ACE Trust or to act as separate trustee of any property, in either case with the powers as may be provided in the instrument of appointment. ACE INA, as depositor, and the administrative trustees shall generally also have the power to vest in that person or persons in that capacity any property, title, right or power deemed necessary or desirable. If an event of default under the corresponding ACE INA subordinated debt securities has occurred and is continuing, the property trustee alone shall have power to make this appointment. (Section 8.9)
 
Merger or Consolidation of ACE Trustees
 
Any corporation into which the property trustee, the Delaware trustee or any administrative trustee that is not a natural person may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the ACE trustee shall be a party, shall be the successor of the ACE trustee under each trust agreement, so long as the corporation is otherwise qualified and eligible. (Section 8.12)
 
Mergers, Consolidations, Amalgamations or Replacements of the ACE Trusts
 
An ACE Trust may not merge with or into, convert into, consolidate, amalgamate, or be replaced by, or convey, transfer or lease its properties and assets substantially as an entirety to any corporation or other entity, except as described below or as described in “Liquidation Distribution Upon Dissolution of ACE Trust.” An ACE Trust may, at the request of ACE INA, with the consent of only the administrative trustees and without the consent of the holders of the preferred securities, merge with or into, convert into, consolidate, amalgamate, or be replaced by or convey, transfer or lease its properties and assets substantially as an entirety to a trust organized as such under the laws of any state so long as the following conditions are met:
 
 	•	 	The successor entity either:	
 
 	•	 	expressly assumes all of the obligations of the ACE Trust with respect to the preferred securities or	
 
 	•	 	substitutes for the preferred securities other securities having substantially the same terms as the preferred securities, referred to in this prospectus as the successor securities, so long as the successor

 	securities rank the same as the preferred securities rank in priority with respect to distributions and payments upon liquidation, redemption and otherwise;	
 
 	•	 	ACE INA expressly appoints a trustee of the successor entity possessing the same powers and duties as the property trustee as the holder of the corresponding ACE INA subordinated debt securities;	
 
 	•	 	The successor securities are listed or traded, or any successor securities will be listed upon notification of issuance, on any national securities exchange or other organization on which the preferred securities are then listed or traded, if any;	
 
 	•	 	The merger, conversion, consolidation, amalgamation, replacement, conveyance, transfer or lease does not cause the preferred securities, including any successor securities, to be downgraded by any nationally recognized statistical rating organization;	
 
 	•	 	The merger, conversion, consolidation, amalgamation, replacement, conveyance, transfer or lease does not adversely affect the rights, preferences and privileges of the holders of the preferred securities, including any successor securities, in any material respect;	
 
 	•	 	The successor entity has a purpose substantially identical to that of the ACE Trust;	
 
 	•	 	Prior to the merger, conversion, consolidation, amalgamation, replacement, conveyance, transfer or lease, ACE INA has received an opinion from independent counsel to the ACE Trust to the effect that:	
 
 	•	 	the merger, conversion, consolidation, amalgamation, replacement, conveyance, transfer or lease does not adversely affect the rights, preferences and privileges of the holders of the preferred securities, including any successor securities, in any material respect, and	
 
 	•	 	following the merger, conversion, consolidation, amalgamation, replacement, conveyance, transfer or lease, neither the ACE Trust nor any successor entity will be required to register as an “investment company” under the Investment Company Act; and	
 
 	•	 	ACE INA or any permitted successor or assignee owns all of the common securities of the successor entity and guarantees the obligations of the successor entity under the successor securities at least to the extent provided by the preferred securities guarantee.	
 
Notwithstanding the preceding description, an ACE Trust shall not, except with the consent of holders of 100% in liquidation amount of the preferred securities, consolidate, amalgamate, merge with or into, convert into, or be replaced by or convey, transfer or lease its properties and assets substantially as an entirety to any other entity or permit any other entity to consolidate, amalgamate, merge with or into, convert into, or replace it if the consolidation, amalgamation, merger, replacement, conveyance, transfer or lease would cause the ACE Trust or the successor entity to be classified as other than a grantor trust for U.S. Federal income tax purposes. (Section 9.5)
 
Voting and Preemptive Rights
 
Except as provided below and under “—Removal of ACE Trustees,” “Description of ACE INA Debt Securities and ACE Guarantee—Events of Default,” “Description of Preferred Securities Guarantees—Amendments and Assignment”, the holders of the preferred securities will generally not have any voting rights. Holders of the preferred securities have no preemptive or similar rights. (Sections 5.14 and 6.1)

Amendment of Restated Trust Agreements
 
Each trust agreement may be amended by ACE INA and the ACE trustees, without the consent of the holders of the trust securities:
 
 	•	 	to cure any ambiguity, correct or supplement any provisions in the trust agreement that may be inconsistent with any other provision, or to make any other provisions with respect to matters or questions arising under the trust agreement, which shall not be inconsistent with the other provisions of the trust agreement, or	
 
 	•	 	to modify, eliminate or add to any provisions of the trust agreement to the extent as shall be necessary to ensure that the ACE Trust will be classified for U.S. Federal income tax purposes as a grantor trust at all times that any trust securities are outstanding or to ensure that the ACE Trust will not be required to register as an “investment company” under the Investment Company Act;	
 
However, in the case of the first bullet above, that action will not adversely affect in any material respect the interests of any holder of trust securities. Any amendments of a trust agreement adopted in accordance with the two bullet points above will become effective when notice of the amendment is given to the holders of trust securities of the applicable ACE Trust.
 
Each trust agreement may be amended by the ACE Trustees and ACE INA with the consent of holders representing not less than a majority, based upon liquidation amounts, of the outstanding trust securities and receipt by the ACE trustees of an opinion of counsel to the effect that the amendment or the exercise of any power granted to the ACE trustees in accordance with the amendment will not affect the ACE Trust’s status as a grantor trust for U.S. Federal income tax purposes or the ACE Trust’s exemption from status as an “investment company” under the Investment Company Act. However, without the consent of each holder of trust securities, the trust agreement may not be amended to:
 
 	•	 	change the amount or timing of any distribution on the trust securities or otherwise adversely affect the amount of any distribution required to be made in respect of the trust securities as of a specified date; or	
 
 	•	 	restrict the right of a holder of trust securities to institute suit for the enforcement of any payment on or after the date. (Section 10.2)	
 
So long as any corresponding ACE INA subordinated debt securities are held by the property trustee, the ACE trustees shall not:
 
 	•	 	direct the time, method and place of conducting any proceeding for any remedy available to the trustee under the ACE INA subordinated indenture, or executing any trust or power conferred on that trustee with respect to the corresponding ACE INA subordinated debt securities;	
 
 	•	 	waive any past default that is waivable under the ACE INA subordinated indenture, as described in “Description of the ACE INA Debt Securities and ACE Guarantee—Modification and Waiver”;	
 
 	•	 	exercise any right to rescind or annul a declaration that the principal of all the ACE INA subordinated debt securities shall be due and payable; or	
 
 	•	 	consent to any amendment, modification or termination of the ACE INA subordinated indenture or the corresponding ACE INA subordinated debt securities, where the consent shall be required, without, in each case, obtaining the prior approval of the holders of a majority in aggregate liquidation amount of all outstanding preferred securities.	
 
However, where a consent under the ACE INA subordinated indenture would require the consent of each holder of the affected corresponding ACE INA subordinated debt securities, no consent shall be given by the property trustee without the prior consent of each holder of the corresponding preferred securities. The ACE

Table of Contents
trustees shall not revoke any action previously authorized or approved by a vote of the holders of the preferred securities except by subsequent vote of the holders of the preferred securities. The property trustee shall notify each holder of preferred securities of any notice of default with respect to the corresponding ACE INA subordinated debt securities. In addition to obtaining these approvals of the holders of the preferred securities, prior to taking any of these actions, the ACE trustees shall obtain an opinion of counsel to the effect that the ACE Trust will not be classified as an association taxable as a corporation for U.S. Federal income tax purposes on account of that action. (Section 6.1)
 
Any required approval or action of holders of preferred securities may be given or taken at a meeting of holders of preferred securities convened for that purpose or pursuant to written consent. The property trustee will cause a notice of any meeting at which holders of preferred securities are entitled to vote to be given to each holder of record of preferred securities. (Sections 6.2, 6.3 and 6.6)
 
No vote or consent of the holders of preferred securities will be required for an ACE Trust to redeem and cancel its preferred securities in accordance with the applicable trust agreement.
 
Even though the holders of preferred securities are entitled to vote or consent under any of the circumstances described above, any of the preferred securities that are owned by ACE INA, the ACE trustees or any affiliate of ACE INA or any ACE trustees shall, for purposes of the vote or consent, be treated as if they were not outstanding.
 
Global Preferred Securities
 
The preferred securities of an ACE Trust may be issued, in whole or in part, in the form of one or more global preferred securities that will be deposited with, or on behalf of, the depositary. The depositary and the specific terms of the depositary arrangement with respect to the preferred securities of an ACE Trust will be described in the applicable prospectus supplement.
 
Payment and Paying Agency
 
Payments of distributions in respect of the preferred securities shall be made to the depositary, which shall credit the relevant accounts at the depositary on the applicable distribution dates, However, if any ACE Trust’s preferred securities are not held by the depositary, these payments shall be made by check mailed to the address of the holder entitled to the payments as it shall appear on the register of the ACE Trust. (Section 4.4)
 
Unless otherwise set forth in the applicable prospectus supplement, the paying agent shall initially be J.P. Morgan Trust Company, National Association and any co-paying agent chosen by J.P. Morgan Trust Company, National Association and acceptable to the administrative trustees and ACE INA. The paying agent shall be permitted to resign as paying agent upon 30 days’ written notice to the administrative trustees, the property trustee and ACE INA. If J.P. Morgan Trust Company, National Association shall no longer be the paying agent, the administrative trustees shall appoint a successor, which shall be a bank or trust company acceptable to the administrative trustees and ACE INA, to act as paying agent. (Section 5.9)
 
Registrar and Transfer Agent
 
Unless otherwise set forth in the applicable prospectus supplement, J.P. Morgan Trust Company, National Association will act as registrar and transfer agent for the preferred securities.
 
Registration of transfers and exchanges of preferred securities will be effected without charge by or on behalf of each ACE Trust. However, the holders must pay any tax or other governmental charges that may be imposed in connection with any transfer or exchange. The ACE Trusts will not be required to register or cause to be registered the transfer of their preferred securities after the preferred securities have been called for redemption. (Section 5.4)

Information Concerning the Property Trustee
 
The property trustee undertakes to perform only those duties specifically set forth in each trust agreement. However, the property trustee must exercise the same degree of care as a prudent person would exercise in the conduct of his or her own affairs. Subject to the preceding sentence, the property trustee is under no obligation to exercise any of the powers vested in it by the applicable trust agreement at the request of any holder of preferred securities unless it is offered reasonable indemnity against the costs, expenses and liabilities that it might incur. If, in performing its duties under the trust agreement, the property trustee is required to decide between alternative causes of action, construe ambiguous provisions in the applicable trust agreement or is unsure of the application of any provision of the applicable trust agreement, and the matter is not one on which holders of preferred securities are entitled under the trust agreement to vote, then the property trustee shall take the action as is directed by ACE INA. Otherwise, the property trustee shall take the action as it deems advisable and in the best interests of the holders of the trust securities and will have no liability except for its own bad faith, negligence or willful misconduct. (Sections 8.1 and 8.3)
 
Administrative Trustees
 
The administrative trustees are authorized and directed to conduct the affairs of and to operate the ACE Trusts in such a way that:
 
 	•	 	no ACE Trust will be deemed to be an “investment company” required to be registered under the Investment Company Act or classified as an association taxable as a corporation for U.S. Federal income tax purposes; and	
 
 	•	 	the corresponding ACE INA subordinated debt securities will be treated as indebtedness of ACE INA for U.S. Federal income tax purposes.	
 
In this regard, ACE INA and the administrative trustees are authorized to take any action not inconsistent with applicable law, the certificate of trust of each ACE Trust or each trust agreement, that ACE INA and the administrative trustees determine, in their discretion, to be necessary or desirable for these purposes, as long as the action does not materially adversely affect the interests of the holders of the related preferred securities.

 DESCRIPTION OF PREFERRED SECURITIES GUARANTEES
 
Concurrently with the issuance by each ACE Trust of its preferred securities, we will execute and deliver a preferred securities guarantee for the benefit of the holders of the preferred securities. J.P. Morgan Trust Company, National Association will act as the guarantee trustee under each preferred securities guarantee for the purposes of compliance with the Trust Indenture Act, and each preferred securities guarantee will be qualified as an indenture under the Trust Indenture Act.
 
The following is a summary of the material provisions of the preferred securities guarantees. You should refer to the form of preferred securities guarantee and the Trust Indenture Act for more complete information regarding the provisions of each preferred securities guarantee. The form of the preferred securities guarantee has been filed as an exhibit to the registration statement of which this prospectus is a part. Reference in this summary to preferred securities means the ACE Trust’s preferred securities to which the preferred securities guarantee relates. The guarantee trustee will hold each preferred securities guarantee for the benefit of the holders of the related ACE Trust’s preferred securities.

We will irrevocably agree to pay in full on a subordinated basis, to the extent described below, the guarantee payments, without duplication of amounts previously paid by or on behalf of the ACE Trust, to the holders of the preferred securities as and when due, regardless of any defense, right of setoff or counterclaim that the ACE Trust may have or assert other than the defense of payment. The following payments with respect to the preferred securities, to the extent not paid by or on behalf of the related ACE Trust, are referred to in this prospectus as the guarantee payments:
 
 	•	 	any accrued and unpaid distributions required to be paid on the preferred securities, to the extent that the ACE Trust has funds available for payment at that time;	
 
 	•	 	the redemption price, including all accrued and unpaid distributions to the redemption date, with respect to any preferred securities called for redemption, to the extent that the ACE Trust has funds available for payment at that time; and	
 
 	•	 	upon a voluntary or involuntary dissolution, winding up or liquidation of the ACE Trust, unless the corresponding ACE INA subordinated debt securities are distributed to holders of the preferred securities, the lesser of:	
 
 	•	 	the liquidation distribution, to the extent the ACE Trust has funds available for payment at that time; and	
 
 	•	 	the amount of assets of the ACE Trust remaining available for distribution to holders of preferred securities.	
 
Our obligation to make a guarantee payment may be satisfied by direct payment of the required amounts by us to the holders of the preferred securities or by causing the ACE Trust to pay these amounts to the holders. (Section 5.1)
 
Each preferred securities guarantee will be an irrevocable guarantee on a subordinated basis of the related ACE Trust’s payment obligations under the preferred securities, but will apply only to the extent that the applicable ACE Trust has funds sufficient to make the payments. Each preferred securities guarantee is, to that extent, a guarantee of payment and not a guarantee of collection. See “—Status of the Preferred Securities Guarantees.”
 
If ACE INA or we does not make interest payments on the corresponding ACE INA subordinated debt securities held by an ACE Trust, the ACE Trust will not be able to pay distributions on the preferred securities and will not have funds legally available for payment. Each preferred securities guarantee will rank subordinate

and junior in right of payment to our senior indebtedness, including all ACE debt securities and ACE’s obligations as guarantor under the ACE INA subordinated indenture, as described below under “—Status of the Preferred Securities Guarantees.”
 
Because we are a holding company, our rights and the rights of our creditors, including the holders of preferred securities who are our creditors by virtue of a preferred securities guarantee, and shareholders to participate in any distribution of assets of any subsidiary upon the subsidiary’s liquidation, reorganization or otherwise would be subject to the prior claims of the subsidiary’s creditors, except to the extent that ACE may itself be a creditor with recognized claims against the subsidiary. The right of our creditors, including the holders of preferred securities who are our creditors by virtue of a preferred securities guarantee, to participate in the distribution of stock owned by us in our subsidiaries, including our insurance subsidiaries, may also be subject to approval by insurance regulatory authorities having jurisdiction over the subsidiaries. Generally, the preferred securities guarantees do not limit our ability to incur or issue other secured or unsecured debt, whether under an indenture or otherwise.
 
Our obligations under preferred securities guarantee, the ACE INA subordinated indenture, including our guarantee of the ACE INA subordinated debt securities, and the expense agreement described below, taken together, constitute a full, irrevocable and unconditional guarantee by us of payments due on the preferred securities. No single document standing alone or operating in conjunction with fewer than all of the other documents constitute this guarantee. It is only the combined operation of these documents that has the effect of providing a full, irrevocable and unconditional guarantee of the ACE Trust’s obligations under the preferred securities. See “The ACE Trusts,” “Description of Preferred Securities,” and “Description of ACE INA Debt Securities and ACE Guarantee.”
 
We will also agree to guarantee the obligations of each ACE Trust with respect to the common securities issued by the ACE Trust to the same extent as under the preferred securities guarantee. However, if an event of default under the ACE INA subordinated indenture has occurred and is continuing, the holders of preferred securities under the preferred securities guarantee will have priority over the holders of the common securities under the common securities guarantee with respect to distributions and payments on liquidation, redemption or otherwise.
 
Status of the Preferred Securities Guarantees
 
Each preferred securities guarantee will constitute our unsecured obligation and will rank subordinate and junior in right of payment to our senior indebtedness, including our debt securities and obligations as guarantor under the ACE INA subordinate indenture. (Section 6.2) For purposes of any preferred securities guarantee, “senior indebtedness” means our indebtedness, including our obligations as guarantor under the ACE INA subordinated indenture, outstanding at any time, except:
 
 	•	 	the indebtedness under the preferred securities guarantee;	
 
 	•	 	indebtedness as to which, by the terms of the instrument creating or evidencing the same, it is provided that the indebtedness is subordinated to or ranks equally with the preferred securities guarantee or to other indebtedness which is subordinated to or ranks equally with the preferred securities guarantee;	
 
 	•	 	indebtedness to an affiliate;	
 
 	•	 	interest accruing after the filing of a petition initiating any bankruptcy, insolvency or other similar proceeding unless the interest is an allowed claim enforceable against us in a proceeding under federal or state bankruptcy laws;	
 
 	•	 	trade accounts payable; and	
 
66

Table of Contents

 	•	 	similar preferred securities guarantees issued by us on behalf of holders of preferred securities of any other ACE Trust or any trust, partnership or other entity affiliated with us which is a financing vehicle of ours or any of our affiliates in connection with the issuance by the entity of preferred securities or other similar securities that are guaranteed by us pursuant to an instrument that ranks equally with or junior in right of payment to the preferred securities guarantee. “Indebtedness” has the same meaning given to that term under the ACE indentures. (Section 1.1)	
 
Each preferred securities guarantee will rank equally with all other similar preferred securities guarantees issued by us on behalf of holders of preferred securities of any other ACE Trust or any trust, partnership or other entity affiliated with us which is a financing vehicle of ours or any affiliate of ours in connection with the issuance by the entity of preferred securities or other similar securities that are guaranteed by us pursuant to an instrument that ranks equally with or junior in right of payment to the preferred securities guarantee. (Section 6.3). Each preferred securities guarantee will constitute a guarantee of payment and not of collection, which means that the guaranteed party may generally institute a legal proceeding directly against us to enforce its rights under the preferred securities guarantee without first instituting a legal proceeding against any other person or entity, including the applicable ACE Trust. (Section 5.4)
 
No preferred securities guarantee will be discharged except by payment of the guarantee payments in full to the extent not paid by the ACE Trust or upon distribution to the holders of the preferred securities of the corresponding ACE INA subordinated debt securities. None of the preferred securities guarantees places a limitation on the amount of additional indebtedness that may be incurred by us. We expect from time to time to incur additional indebtedness that will rank senior to the preferred securities guarantees.
 
Payment of Additional Amounts
 
ACE will make all guarantee payments without withholding or deduction at source for, or on account of, any present or future taxes, fees, duties, assessments or governmental charges of whatever nature imposed or levied by or on behalf of the jurisdiction of ACE’s organization or principal executive offices, each referred to in this prospectus as a taxing jurisdiction, or any political subdivision or taxing authority of the taxing jurisdiction, unless the taxes, fees, duties, assessments or governmental charges are required to be withheld or deducted by:
 
 	•	 	the laws or any regulations or rulings promulgated under the laws of a taxing jurisdiction or any political subdivision or taxing authority of the taxing jurisdiction; or	
 
 	•	 	an official position regarding the application, administration, interpretation or enforcement of any laws, regulations or rulings, including, without limitation, a holding by a court of competent jurisdiction or by a taxing authority in a taxing jurisdiction or any political subdivision of the taxing jurisdiction.	
 
If a withholding or deduction at source is required, ACE will, subject to limitations and exceptions described below, pay to the holder of any related preferred securities the additional amounts as may be necessary so that every guarantee payment made to the holder, after this withholding or deduction, will not be less than the amount provided for in the preferred securities guarantee to be then due and payable.
 
ACE will not be required to pay any additional amounts for or on account of:
 
 	•	 	any tax, fee, duty, assessment or governmental charge of whatever nature which would not have been imposed but for the fact that you:	
 
 	•	 	were a resident, domiciliary or national of, or engaged in business or maintained a permanent establishment or were physically present in, the relevant taxing jurisdiction or any political subdivision of the taxing jurisdiction or otherwise had some connection with the relevant taxing jurisdiction other	
 
67

Table of Contents

 	than by reason of the mere ownership of preferred securities, or receipt of payment under the preferred securities;	
 
 	•	 	presented the preferred security for payment in the relevant taxing jurisdiction or any political subdivision of the taxing jurisdiction, unless the preferred security could not have been presented for payment elsewhere; or	
 
 	•	 	presented the preferred security for payment more than 30 days after the date on which the payment in respect of the preferred security first became due and payable or provided for, whichever is later, except to the extent that you would have been entitled to the additional amounts if you had presented the preferred security for payment on any day within that 30-day period;	
 
 	•	 	any estate, inheritance, gift, sale, transfer, personal property or similar tax, assessment or other governmental charge;	
 
 	•	 	any tax, assessment or other governmental charge that is imposed or withheld by reason of the failure by you or the beneficial owner of the preferred security to comply with any reasonable request by ACE or the applicable ACE Trust addressed to you within 90 days of the request to:	
 
 	•	 	provide information concerning your nationality, residence or identity or of the beneficial owner; or	
 
 	•	 	make any declaration or other similar claim or satisfy any information or reporting requirement, which in either case is required or imposed by statute, treaty, regulation or administrative practice of the relevant taxing jurisdiction or any political subdivision of the taxing jurisdiction as a precondition to exemption from all or part of the tax, assessment or other governmental charge; or	
 
 	•	 	any combination of the above items.	
 
In addition, ACE will not pay you any additional amounts with respect to any guarantee payment if you are a fiduciary or partnership or other than the sole beneficial owner of the related preferred security, to the extent the payment would be required by the laws of the relevant taxing jurisdiction, or any political subdivision or relevant taxing authority of or in the taxing jurisdiction, to be included in the income for tax purposes of a beneficiary or partner or settlor with respect to the fiduciary or a member of the partnership or a beneficial owner who would not have been entitled to the additional amounts had it been the holder of the preferred security. (Section 5.8)
 
Amendments and Assignment
 
No preferred securities guarantee may be amended without the prior approval of the holders of not less than a majority of the aggregate liquidation amount of the outstanding preferred securities, except with respect to any changes which do not materially adversely affect the rights of holders of the related preferred securities, in which case no consent will be required. (Section 8.2) All guarantees and agreements contained in each preferred securities guarantee will bind our successors and assigns and will inure to the benefit of the holders of the related preferred securities. (Section 8.1) We may not assign our obligations under the preferred securities guarantee except in connection with a consolidation, amalgamation or merger or conveyance, transfer or lease that is permitted under the ACE INA subordinated indenture and under which the person formed by the consolidation or amalgamation or into which we are merged or which acquires or leases our properties and assets agrees in writing to perform our obligations under the preferred securities guarantee.
 
Events of Default
 
An event of default under each preferred securities guarantee will occur upon our failure to perform any of our payment or other obligations under the preferred securities guarantee. The holders of not less than a majority in aggregate liquidation amount of the related preferred securities have the right to direct the time, method and
 
68

Table of Contents
place of conducting any proceeding for any remedy available to the guarantee trustee or to direct the exercise of any trust or power conferred upon the guarantee trustee. (Section 5.4)
 
Any holder of the preferred securities may institute a legal proceeding directly against us to enforce its rights under the preferred securities guarantee without first instituting a legal proceeding against the ACE Trust, the guarantee trustee or any other person or entity. (Section 5.4)
 
We, as guarantor, are required to file annually with the guarantee trustee a certificate as to whether or not ACE is in compliance with all the conditions and covenants applicable to it under the preferred securities guarantee. (Section 2.4)
 
Information Concerning the Guarantee Trustee
 
The guarantee trustee, other than during the occurrence and continuance of a default by us in performance of any preferred securities guarantee, undertakes to perform only the duties specifically set forth in each preferred securities guarantee. After default with respect to any preferred securities guarantee, the guarantee trustee must exercise the same degree of care and skill as a prudent person would exercise or use in the conduct of his or her own affairs. (Section 3.1) Subject to the preceding sentence, the guarantee trustee is under no obligation to exercise any of the powers vested in it by any preferred securities guarantee at the request of any holder of any preferred securities unless it is offered reasonable indemnity against the costs, expenses, and liabilities that it might incur. (Section 3.2)
 
Termination of the Preferred Securities Guarantees
 
Each preferred securities guarantee will terminate upon:
 
 	•	 	full payment of the redemption price of the related preferred securities;	
 
 	•	 	the distribution of the corresponding ACE INA subordinated debt securities to the holders of the related preferred securities; or	
 
 	•	 	upon full payment of the amounts payable upon liquidation of the related ACE Trust.	
 
Each preferred securities guarantee will continue to be effective or will be reinstated if, at any time, any holder of the related preferred securities must restore payment of any sums paid with respect to the preferred securities or the preferred securities guarantee. (Section 7.1)
 
New York Law to Govern
 
Each preferred securities guarantee will be governed by and construed in accordance with the laws of the State of New York. (Section 8.5)
 
The Expense Agreement
 
Pursuant to the expense agreement entered into by us under each trust agreement, we will irrevocably and unconditionally guarantee to each person or entity to whom an ACE Trust becomes indebted or liable, the full payment of any costs, expenses or liabilities of the ACE Trust, other than obligations of the ACE Trust to pay to the holders of the preferred securities or other similar interests in the ACE Trust of the amounts due them pursuant to the terms of the preferred securities or other similar interests, as the case may be.

 ENFORCEMENT OF CIVIL LIABILITIES UNDER
UNITED STATES FEDERAL SECURITIES LAWS
 
ACE is a Cayman Islands company. In addition, some of its officers and directors, as well as some of the experts named in this prospectus, reside outside the United States, and all or much of ACE’s assets and some of the officers’ and directors’ assets are or may be located in jurisdictions outside the United States. Therefore, investors may have difficulty effecting service of process within the United States upon those persons or recovering against ACE or them on judgments of U.S. courts, including judgments based upon the civil liability provisions of the U.S. Federal securities laws. However, investors may serve ACE with process in the United States with respect to actions against it arising out of or in connection with violations of U.S. Federal securities laws relating to offers and sales of the securities covered by this prospectus by serving ACE INA Holdings, its United States agent irrevocably appointed for that purpose.
 
ACE has been advised by Maples and Calder, its Cayman Islands counsel, that there is doubt as to whether the courts of the Cayman Islands would enforce:
 
 	•	 	judgments of U.S. courts based upon the civil liability provisions of the U.S. Federal securities laws obtained in actions against it or its directors and officers, as well as experts named in this prospectus, who reside outside the United States; or	
 
 	•	 	original actions brought in the Cayman Islands against these persons or ACE predicated solely upon U.S. Federal securities laws.	
 
ACE has also been advised by Maples and Calder that there is no treaty in effect between the United States and the Cayman Islands providing for this enforcement, and there are grounds upon which Cayman Islands courts may not enforce judgments of United States courts. Some remedies available under the laws of United States jurisdictions, including some remedies available under the U.S. Federal securities laws, would not be allowed in Cayman Islands courts as contrary to that nation’s public policy.

The ACE Trusts
 
There are no separate financial statements of the ACE Trusts in this prospectus. ACE does not believe the financial statements would be helpful to the holders of the preferred securities of the ACE Trusts because:

 	•	 	neither of the ACE Trusts has any independent operations or proposes to engage in any activity other than issuing securities representing undivided beneficial interests in the assets of the ACE Trust and investing the proceeds in subordinated debt securities issued by ACE INA and fully and unconditionally guaranteed by ACE; and	
 
 	•	 	the obligations of each ACE Trust under the preferred securities will be fully and unconditionally guaranteed by ACE. See “Description of ACE INA Debt Securities and ACE Guarantee” and “Description of Preferred Securities Guarantees.”	
 
Neither of the ACE Trusts is currently subject to the information reporting requirements of the Exchange Act. Each ACE Trust will be exempt from these requirements following the effectiveness of the registration statement that contains this prospectus.
