NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
1. General
ACE Limited (ACE or the Company) is a holding company incorporated with limited liability under the Cayman Islands Companies Law and maintains its corporate business office in Bermuda. The Company, through its various subsidiaries, provides a broad range of insurance and reinsurance products to insureds worldwide. ACE operates through the following business segments: Insurance – North American, Insurance – Overseas General, Global Reinsurance, and Life Insurance and Reinsurance. These segments are described in Note 4.
The interim unaudited consolidated financial statements, which include the accounts of the Company and its subsidiaries, have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) and, in the opinion of management, reflect all adjustments (consisting of normally recurring accruals) necessary for a fair presentation of the results and financial position for such periods. All significant intercompany accounts and transactions have been eliminated. Certain items in the prior period financial statements have been reclassified to conform to the current period presentation. The results of operations and cash flows for any interim period are not necessarily indicative of the results for the full year. These financial statements should be read in conjunction with the consolidated financial statements, and related notes thereto, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2006.
2. Significant accounting policies
New accounting pronouncements
Adopted in 2007
Accounting for uncertainty in income taxes
In July 2006, the Financial Accounting Standards Board (FASB) issued FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes—an interpretation of FASB Statement No. 109 (FIN 48). FIN 48 clarifies the accounting for uncertainty in tax positions by prescribing a financial statement recognition threshold and measurement attribute for uncertain tax positions taken or expected to be taken in a tax return. Further, FIN 48 expands the required disclosures associated with such uncertain tax positions. The Company adopted FIN 48 as of January 1, 2007, and the cumulative effect of adoption resulted in a reduction to retained earnings of $22 million. For additional information regarding the adoption of FIN 48, refer to Note 9.
Accounting for certain hybrid financial instruments
In February 2006, the FASB issued Financial Accounting Standard (FAS) No. 155, Accounting for Certain Hybrid Financial Instruments — an amendment of FASB Statements No. 133 and 140 (FAS 155). FAS 155 permits fair value re-measurement of an entire hybrid financial instrument that contains an embedded derivative that otherwise would require bifurcation, establishes a requirement to evaluate interests in securitized financial assets for either freestanding derivatives or embedded derivatives requiring bifurcation, narrows the scope exemption applicable to interest-only strips and principal-only strips from FAS 133, and clarifies that concentrations of credit risk in the form of subordination are not embedded derivatives. In December 2006, the FASB issued implementation guidance, Statement 133 Implementation Issue B40 Embedded Derivatives: Application of Paragraph 13(b) to Securitized Interests in Prepayable Financial Assets (DIG B40), which limits the circumstances in which prepayment risk within a securitized interest would be considered an embedded derivative. To facilitate transition, securitized interests issued before June 30, 2007, containing insignificant embedded derivatives are not subject to paragraph 13(b).
ACE adopted FAS 155, as amended for the FASB implementation guidance DIG B40, as of January 1, 2007. The adoption of FAS 155 did not have a material impact on the Company’s financial condition or results of operations. Upon adopting FAS 155 on January 1, 2007, the Company elected to apply the option provided in

FAS 155 related to hybrid financial instruments to $277 million of convertible bond investments within ACE’s available for sale portfolio. Since the convertible bonds were previously carried at fair value, the election did not have an effect on shareholders’ equity. However, the election resulted in a reduction of accumulated other comprehensive income and an increase in retained earnings of $12 million as of January 1, 2007. The $12 million of net unrealized gains is comprised of securities with unrealized gains of $14 million and unrealized losses of $2 million.
To be adopted after September 30, 2007
Fair value measurements
In September 2006, the FASB issued FAS No. 157, Fair Value Measurements (FAS 157). FAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. FAS 157 focuses on how to measure fair value and establishes a three-level hierarchy for both measurement and disclosure purposes. The fair value hierarchy gives the highest priority to quoted prices in active markets and the lowest priority to unobservable data. Under FAS 157, fair value measurements would be separately disclosed by level within the fair value hierarchy. FAS 157 does not expand the use of fair value to any new circumstances. The Company is currently evaluating the impact, if any, of adopting FAS 157 on its financial condition and results of operations.
Fair value option
In February 2007, the FASB issued FAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities (FAS 159). FAS 159 permits an entity to irrevocably elect fair value on a contract-by-contract basis as the initial and subsequent measurement attribute for many financial assets and liabilities and certain other items including insurance contracts. Entities electing the fair value option would be required to recognize changes in fair value in earnings and to expense upfront costs and fees associated with the item for which the fair value option is elected. FAS 159 is effective for fiscal years beginning after November 15, 2007. The Company is currently evaluating which financial assets and liabilities, if any, to measure at fair value upon adoption of FAS 159 on January 1, 2008. The impact, if any, of adopting FAS 159 on the Company’s financial condition or results of operations is limited to those financial assets and liabilities for which the fair value option is elected.
3. Share-based compensation
During 2004, the Company established the ACE Limited 2004 Long-Term Incentive Plan (the 2004 LTIP). The Company’s 2004 LTIP provides for grants of both incentive and non-qualified stock options principally at an option price per share of 100 percent of the fair market value of the Company’s Ordinary Shares on the date of grant. Stock options are generally granted with a 3-year vesting period and a 10-year term. The stock options vest in equal annual installments over the respective vesting period, which is also the requisite service period. On February 28, 2007, the Company granted 1,522,876 stock options with a weighted-average grant date fair value of $15.73. The fair value of the options issued is estimated on the date of grant using the Black-Scholes option pricing model.
The Company’s 2004 LTIP also provides for grants of restricted stock and restricted stock units. The Company generally grants restricted stock and restricted stock units with a 4-year vesting period, based on a graded vesting schedule. The restricted stock is granted at market close price on the day of grant. On February 28, 2007, the Company granted 1,691,319 shares of restricted stock at a grant date fair value of $56.14. Each restricted stock unit represents the Company’s obligation to deliver to the holder one share of Ordinary Shares upon vesting. On February 28, 2007, the Company awarded 106,160 restricted stock units to officers of the Company and its subsidiaries with a grant date fair value of $56.14.

The Company also grants restricted stock units with a 1-year vesting period to non-management directors. Delivery of Ordinary Shares on account of these restricted stock units to non-management directors is deferred until six months after the date of the non-management directors’ termination from the Board. On May 17, 2007, the Company awarded 28,004 restricted stock units to non-management directors with a grant date fair value of $61.42.
4. Segment information
The Company operates through the following business segments: Insurance – North American, Insurance – Overseas General, Global Reinsurance, and Life Insurance and Reinsurance. These segments distribute their products through various forms of brokers and agencies. Insurance – North American, Insurance – Overseas General, and Global Reinsurance utilize direct marketing programs to reach clients. Additionally, Insurance – North American has formed internet distribution channels for some of its products. Global Reinsurance, Insurance – North American, and Life Insurance and Reinsurance have established relationships with reinsurance intermediaries.
The Insurance – North American segment comprises the P&C operation in the U.S., Canada, and Bermuda. This segment includes the operations of ACE USA (including ACE Canada), ACE Westchester Specialty, ACE Bermuda, and various run-off operations. ACE USA provides a broad range of 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, medical liability, aerospace, A&H coverages, as well as claims and risk management products and services. The financial solutions business includes insurance and reinsurance solutions to complex risks that generally cannot be adequately addressed by the traditional insurance marketplace. It consists of securitization and risk trading, finite and structured risk products, and retroactive contracts in the form of loss portfolio transfers. 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. The run-off operations include Brandywine Holdings Corporation, Commercial Insurance Services, residual market workers’ compensation business, pools and syndicates not attributable to a single business group, the run-off of open market facilities, and other exited lines of business. Run-off operations do not actively sell insurance products, but are responsible for the management of existing policies and related claims.
The Insurance – Overseas General segment consists of ACE International (excluding its life insurance business) and the wholesale insurance operations of ACE Global Markets. The segment has four regions of operations: the ACE European Group (which is comprised of ACE Europe and ACE Global Markets branded business), ACE Asia Pacific, ACE Far East, and ACE Latin America. ACE International comprises ACE INA’s network of indigenous retail insurance operations, which provide insurance coverage on a world-wide basis. ACE Global Markets comprises our insurance operations within ACE European Group Limited and at Lloyd’s via Syndicate 2488. ACE provides funds at Lloyd’s to support underwriting by Syndicate 2488. The reinsurance operation of ACE Global Markets is included in the Global Reinsurance segment. Companies within the Insurance – Overseas General segment write a variety of insurance products including property, casualty, professional lines (D&O and E&O), marine, energy, aviation, political risk, consumer-oriented products, and A&H (principally accident and supplemental health).
The Global Reinsurance segment comprises ACE Tempest Re Bermuda, ACE Tempest Re USA, ACE Tempest Re Europe, and ACE Tempest Re Canada. These divisions provide a broad range of property catastrophe, casualty, and property reinsurance coverages to a diverse array of primary P&C companies.

The Life Insurance and Reinsurance segment includes the operations of ACE Tempest Life Re (ACE Life Re) and ACE International Life (ACE Life). ACE Life Re provides reinsurance coverage to other life insurance companies as well as marketing traditional life reinsurance products and services for the individual life business. ACE Life provides traditional life insurance protection, investment, and savings products to individuals in several countries including Thailand, Vietnam, Taiwan, China, and Egypt.
Corporate and Other (Corporate) includes ACE Limited and ACE INA Holdings, Inc. and intercompany eliminations. In addition, Corporate includes the Company’s proportionate share of Assured Guaranty’s earnings reflected in Other (income) expense. Included in Losses and loss expenses are losses incurred in connection with the commutation of ceded reinsurance contracts that resulted from a differential between the consideration received from reinsurers and the related reduction of reinsurance recoverable, principally related to the time value of money. Due to the Company’s initiatives to reduce reinsurance recoverable balances and thereby encourage such commutations, losses recognized in connection with the commutation of ceded reinsurance contracts are generally not considered when assessing segment performance and, accordingly, are directly allocated to Corporate. As such, the effect of the related loss reserve development on net income is reported within Corporate.
For segment reporting purposes, certain items have been presented in a different manner than in the consolidated financial statements.  The following tables summarize the operations by segment for the periods indicated.

For the nine months ended September 30, 2007 and 2006, the potential anti-dilutive share conversions were 268,501 and 360,095, respectively.
6. Investments
a) Gross unrealized loss
As of September 30, 2007, there were 7,566 fixed maturities out of a total of 14,469 fixed maturities in an unrealized loss position. The largest single unrealized loss of the fixed maturities was $1.7 million. There were

334 equity securities out of a total of 1,166 equity securities in an unrealized loss position. The largest single unrealized loss in the equity securities was $2.6 million. There were no securities that had been in a loss position for the previous nine consecutive months with a market value of less than 80 percent of amortized cost, or cost for equity securities. Most of the fixed maturities in an unrealized loss position were investment grade securities for which fair value declined due to increases in market interest rates from the date of purchase.
The following tables summarize, for all securities in an unrealized loss position at September 30, 2007, and December 31, 2006 (including securities on loan), the aggregate fair value and gross unrealized loss by length of time the security has continuously been in an unrealized loss position.

b) Other- than- temporary impairments
The following table shows, for the periods indicated, the losses included in Net realized gains (losses) as a result of conditions which caused the Company to conclude the decline in fair value of certain investments was “other-than-temporary”. The impairments during the nine months ended September 30, 2007, are primarily due to an increase in market interest rates from the date of security purchase.

7. Debt
In February 2007, ACE INA issued $500 million of 5.7 percent notes due in February 2017. These notes are redeemable at any time at ACE INA’s option subject to a “make-whole” premium plus 0.20 percent. The notes are also redeemable at par plus accrued and unpaid interest in the event of certain changes in tax law. These notes do not have the benefit of any sinking fund. These senior unsecured notes are guaranteed on a senior basis by the Company and they rank equally with all of the Company’s other senior obligations. They also contain a customary limitation on lien provisions as well as customary events of default provisions which, if breached, could result in the accelerated maturity of such senior debt.
On April 2, 2007, the Company repaid the $500 million 6.0 percent ACE Limited senior notes due April 2007.
8. Commitments, contingencies, and guarantees
a) Other investments
The Company invests in limited partnerships with a carrying value of $377 million included in Other investments. In connection with these investments, the Company has commitments that may require funding of up to $731 million over the next several years.
b) Legal proceedings
(i) Claims and Other Litigation
The Company’s insurance subsidiaries are subject to claims litigation involving disputed interpretations of policy coverages and, in some jurisdictions, direct actions by allegedly-injured persons seeking damages from policyholders. These lawsuits, involving claims on policies issued by the Company’s subsidiaries which are typical to the insurance industry in general and in the normal course of business, are considered in the Company’s loss and loss expense reserves. In addition to claims litigation, the Company and its subsidiaries are subject to lawsuits and regulatory actions in the normal course of business that do not arise from, or directly relate to, claims on insurance policies. This category of business litigation typically involves, amongst other things, allegations of underwriting errors or misconduct, employment claims, regulatory activity, or disputes arising from business ventures. In the opinion of ACE’s management, ACE’s ultimate liability for these matters is not likely to have a material adverse effect on ACE’s consolidated financial condition, although it is possible that the effect could be material to ACE’s consolidated results of operations for an individual reporting period.

(ii) Subpoenas
Beginning in 2004, ACE and its subsidiaries and affiliates received numerous subpoenas, interrogatories, and civil investigative demands in connection with certain investigations of insurance industry practices. These inquiries have been issued by a number of attorneys general, state departments of insurance, and other authorities, including the New York Attorney General (NYAG), the Pennsylvania Department of Insurance, and the Securities and Exchange Commission (SEC). These inquiries seek information concerning underwriting practices and non-traditional or loss mitigation insurance products. To the extent they are ongoing, ACE is cooperating and will continue to cooperate with such inquiries.
ACE conducted its own investigation that encompassed the subjects raised by the NYAG and the other state and federal regulatory authorities. The investigation was conducted by a team from the firm of Debevoise & Plimpton LLP headed by former United States Attorney Mary Jo White and operated under and at the direction of the Audit Committee of the Board of Directors. ACE’s internal investigations pertaining to underwriting practices and non-traditional or loss mitigation insurance products are complete.
(iii) Settlement Agreements
On April 25, 2006, ACE reached a settlement with the Attorneys General of New York, Illinois, and Connecticut and the New York Insurance Department pursuant to which ACE received from these authorities an Assurance of Discontinuance (AOD). Under the AOD, these regulators agreed not to file certain litigation against ACE relating to their investigation of certain business practices, and ACE agreed to pay $80 million ($66 million after tax) without admitting any liability, and to adopt certain business reforms. Of that $80 million, $40 million was paid to the three settling Attorneys General as a penalty. The remaining $40 million was placed in a fund allocated for distribution to eligible policyholders who execute a release of certain claims they may have against ACE. Approximately $39 million of this $40 million has been distributed to such policyholders. ACE first may use the sums remaining to settle these or similar types of policyholder claims, and then shall use any sums remaining after such settlements to provide additional amounts to those policyholders who initially executed the release. A total of $80 million was recorded in administrative expenses in the quarter ended March 31, 2006.
On May 9, 2007, ACE and the Pennsylvania Insurance Department (Department) and the Pennsylvania Office of Attorney General (OAG) entered into a settlement agreement. This settlement agreement resolves the issues raised by the Department and the OAG arising from their investigation of ACE’s underwriting practices and contingent commission payments. As a result of this settlement agreement, ACE made a $9 million payment to the Department and agreed to comply with the business practice guidelines that ACE established in 2004 to assure ongoing antitrust compliance in its operations.
On October 24, 2007, ACE entered into a settlement agreement with the Attorneys General of Florida, Hawaii, Maryland, Massachusetts, Michigan, Oregon, Texas, West Virginia and the District of Columbia, and the Florida Department of Financial Services and Office of Insurance Regulation. The agreement resolves investigations of ACE's underwriting practices and contingent commission payments. Under the agreement, ACE agreed to pay $4.5 million without admitting any liability, and to keep in place certain business reforms already in effect.
(iv) Business Practice-Related Litigation
ACE, ACE INA Holdings, Inc., and ACE USA, Inc., along with a number of other insurers and brokers, were named in a series of federal putative nationwide class actions brought by insurance policyholders. The Judicial Panel on Multidistrict Litigation (JPML) consolidated these cases in the District of New Jersey. On August 1, 2005, plaintiffs in the New Jersey consolidated proceedings filed two consolidated amended complaints—one concerning commercial insurance and the other concerning employee benefit plans. The employee benefit plans litigation against ACE has been dismissed.

In the commercial insurance complaint, the plaintiffs named ACE, ACE INA Holdings, Inc., ACE USA, Inc., ACE American Insurance Co., Illinois Union Insurance Co., and Indemnity Insurance Co. of North America. They allege that certain brokers and insurers, including certain ACE entities, conspired to increase premiums and allocate customers through the use of “B” quotes and contingent commissions. In addition, the complaints allege that the broker defendants received additional income by improperly placing their clients’ business with insurers through related wholesale entities that acted as intermediaries between the broker and insurer. Plaintiffs also allege that broker defendants tied the purchase of primary insurance to the placement of such coverage with reinsurance carriers through the broker defendants’ reinsurance broker subsidiaries. The complaint asserts the following causes of action against ACE: Federal Racketeer Influenced and Corrupt Organizations Act (RICO), federal antitrust law, state antitrust law, aiding and abetting breach of fiduciary duty, and unjust enrichment.
On November 29, 2005, ACE and other property and casualty insurer defendants filed motions to dismiss the commercial insurance complaint. On February 13, 2006, plaintiffs filed motions to certify a class in the commercial insurance case (this motion has been fully briefed and is pending). On October 3, 2006, the Court ruled on defendants’ motions and held that the McCarran Ferguson Act did not apply as a defense to the allegations, but the Court also held that plaintiffs had not adequately alleged an antitrust conspiracy or a RICO enterprise and directed plaintiffs to submit supplemental pleadings. Plaintiffs filed their supplemental pleadings on October 25, 2006. On November 30, 2006, defendants filed a renewed motion to dismiss. On April 5, 2007, the Court granted defendants’ renewed motion and dismissed the consolidated complaint without prejudice for failure to state a claim under either the Sherman Act or the RICO statutes. The Court permitted plaintiffs one final opportunity to re-plead and an amended complaint was filed on May 22, 2007. The amended complaint purported to add several new ACE defendants: ACE Group Holdings, Inc., ACE US Holdings, Inc., Westchester Fire Insurance Company, INA Corporation, INA Financial Corporation, INA Holdings Corporation, ACE Property and Casualty Insurance Company, and Pacific Employers Insurance Company. Plaintiffs also added a new antitrust claim against Marsh, ACE, and other insurers based on the same allegations as the other claims but limited to excess casualty insurance. On June 21, 2007, defendants moved to dismiss the amended complaint and moved to strike the new parties that plaintiffs attempted to add to that complaint. The Court granted defendants’ motions to dismiss and dismissed plaintiffs’ antitrust and RICO claims with prejudice on August 31, 2007 and September 28, 2007, respectively. By order dated September 28, 2007, the Court declined to exercise supplemental jurisdiction over plaintiffs’ state law claims and dismissed those claims without prejudice. On October 10, 2007, plaintiffs filed a Notice of Appeal of the antitrust and RICO rulings to the United States Court of Appeals for the Third Circuit.
In New Cingular Wireless Headquarters LLC et al. v. Marsh & McLennan Companies, Inc. et al. (Case No. 06-5120; United States District Court for the District of New Jersey), a non-class-action lawsuit filed in the Northern District of Georgia on April 4, 2006, but later transferred to the District of New Jersey for coordination with the consolidated cases described above, the plaintiffs named the following entities: ACE Ltd., ACE American Ins. Co., ACE USA, Inc., ACE Bermuda Ins. Co. Ltd., Illinois Union Ins. Co., Pacific Employers Ins. Co., and Lloyd’s of London Syndicate 2488 AGM, along with a number of other insurers and brokers. The plaintiffs are insurance policyholders who allege that the defendants conspired to increase premiums and allocate customers through the use of “B” quotes and contingent commissions. The plaintiffs assert the following causes of action against ACE: RICO, federal antitrust law, inducement to breach of fiduciary duty, unjust enrichment, and fraud. All proceedings in this action are stayed pending a ruling by the Court on certain motions in the employee benefits litigation referenced above (in which ACE is not a party). Most of the defendants in this action and the other consolidated actions in the District of New Jersey have asked the Court to continue the stay until the United States Court of Appeals for the Third Circuit rules on plaintiffs’ appeal of the August 31, 2007, and September 28, 2007, antitrust and RICO rulings.

ACE, ACE INA Holdings, Inc., ACE USA, Inc., and ACE American Insurance Co., along with a number of other insurers and brokers, have been named in Avery Dennison Corp. v. Marsh & McLennan Companies, Inc. et al. (Case No. 07-00757) (filed February 13, 2007, in the District of New Jersey). The allegations in this case are also similar to the allegations in the consolidated federal actions identified above. On April 3, 2007, the court issued an order consolidating this case with the consolidated federal actions identified above. As addressed in the preceding paragraph, all proceedings in this action are currently stayed.
ACE USA, Inc., along with a number of other insurers and Marsh, has been named as a defendant in Henley Management Co., Inc. et al v. Marsh, Inc. et al. (Case No. 07-2389) (filed May 27, 2007, in the District of New Jersey). The allegations in this case are similar to the allegations in the consolidated federal actions identified above. On July 11, 2007, the Court issued an order consolidating this case with the consolidated federal actions. As addressed in the preceding two paragraphs, all proceedings in this action are currently stayed.
Lloyd’s of London Syndicate 2488 AGM, along with a number of other Lloyd’s of London Syndicates and various brokers, has been named as a defendant in two actions: Lincoln Adventures LLC et al. v. Those Certain Underwriters at Lloyd’s, London Members of Syndicates 0033 et al. (Case No. 07-60991) (filed July 13, 2007, in the Southern District of Florida), and Supreme Auto Transport LLC et al. v. Certain Underwriters of Lloyd’s of London, et al. (Case No. 07-6703) (filed July 25, 2007, in the Southern District of New York). The allegations in these putative class-action lawsuits are similar to the allegations in the consolidated federal actions identified above, although these lawsuits focus on alleged conduct within the London insurance market. Both cases have been conditionally transferred to the above-referenced multidistrict litigation in the District of New Jersey. The plaintiffs have opposed the conditional transfer, and the parties are awaiting a final decision from the Judicial Panel on Multidistrict Litigation on this issue.
ACE American Insurance Co., ACE Bermuda Insurance Ltd., and Westchester Surplus Lines Insurance Co., along with a number of other insurers and brokers, have recently been named in Sears, Roebuck & Co. et al. v. Marsh & McLennan Companies, Inc. et al. (Case No. 07-2535) (filed October 12, 2007, in the Northern District of Georgia). The allegations in this case are similar to the allegations in the consolidated federal actions identified above, and this case will likely be consolidated with those actions in the District of New Jersey.
Illinois Union Insurance Company, an ACE subsidiary, has been named in a state court class action: Van Emden Management Corporation v. Marsh & McLennan Companies, Inc., et al. (Case No. 05-0066A; Superior Court of Massachusetts) (filed January 13, 2005). The allegations in this case are similar to the allegations in the federal class actions identified above. The Van Emden case has been stayed pending resolution of the consolidated proceedings in the District of New Jersey or until further order of the Court.
ACE American Insurance Co., an ACE subsidiary, has been named in a state court lawsuit in Florida: Office Depot, Inc. v. Marsh & McLennan Companies, Inc. et al. (Case No. 502005CA004396; Circuit Court of the 15th Judicial Circuit in Palm Beach County Florida) (filed June 22, 2005). The allegations in this case are also similar to the allegations in the federal class actions identified above. The trial court originally stayed the Office Depot case pending resolution of the consolidated proceedings in the District of New Jersey. The Florida Court of Appeals recently remanded the case to the trial court with instructions to reconsider whether a stay should be granted. On February 23, 2007, the trial court declined to grant another stay and ordered the defendants to respond to the complaint within the next twenty days. On March 15, 2007, defendants filed a motion to dismiss the complaint. On September 24, 2007, the court denied defendants’ motion to dismiss. Discovery is ongoing.
ACE, ACE American Insurance Co., ACE Property & Casualty Insurance Co., Insurance Company of North America, and Westchester Fire Insurance Co., along with a number of other insurance companies and Marsh,

have been named in a state court lawsuit filed by the Ohio Attorney General: State of Ohio, ex. rel. Marc E. Dann, Attorney General v. American Int’l Group, Inc. et al. (Case No 07-633857) (filed August 24, 2007 in the Court of Common Pleas in Cuyahoga County, Ohio). The allegations in this case are similar to the allegations in the federal actions identified above. ACE plans to file a motion to dismiss the complaint on November 16, 2007. Discovery is currently stayed pending the earlier of May 2008 or a ruling on defendants’ motions to dismiss.
ACE was named in four putative securities class action suits following the filing of a civil suit against Marsh by the NYAG on October 14, 2004. The suits were consolidated by the JPML in the Eastern District of Pennsylvania. The Court has appointed as lead plaintiffs Sheet Metal Workers’ National Pension Fund and Alaska Ironworkers Pension Trust. Lead plaintiffs filed a consolidated amended complaint on September 30, 2005, naming ACE, Evan G. Greenberg, Brian Duperreault, and Philip V. Bancroft as defendants. Plaintiffs allege that ACE’s public statements and securities filings should have revealed that insurers, including certain ACE entities, and brokers allegedly conspired to increase premiums and allocate customers through the use of “B” quotes and contingent commissions and that ACE’s revenues and earnings were inflated by these practices. Plaintiffs assert claims solely under Section 10(b) of the Securities Exchange Act of 1934 (the Exchange Act), Rule 10(b)-5 promulgated thereunder, and Section 20(a) of the Securities Act (control person liability).
On October 28, 2005, ACE and the individual defendants filed a motion to dismiss the consolidated securities actions. Defendants argued that plaintiffs had not adequately alleged any actionable misrepresentations under the securities laws, and that defendants could not be held liable for any failures to disclose information. Defendants also argued that the individual defendants could not be held liable for statements they did not make; that plaintiffs had not adequately pled defendants’ knowledge of any misstatements; and that plaintiffs had not adequately pled loss causation. Plaintiffs have filed a response and the motion remains pending.
ACE has been named as a defendant in a derivative suit filed in Delaware Chancery Court by shareholders of Marsh seeking to recover damages for Marsh and its subsidiary, Marsh, Inc., against officers and directors of Marsh, American International Group Inc. (AIG), AIG’s chief executive officer, and ACE. The suit alleges that the defendants breached their fiduciary duty to and thereby damaged Marsh and Marsh, Inc. by participating in a bid rigging scheme and obtaining “kickbacks” in the form of contingent commissions, and that ACE knowingly participated in the alleged scheme.
ACE, ACE USA, Inc., ACE INA Holdings, Inc., and Evan G. Greenberg, as a former officer and director of AIG and current officer and director of ACE, have been named in one or both of two derivative cases brought by certain shareholders of AIG. One of the derivative cases was filed in Delaware Chancery Court, and the other was filed in federal court in the Southern District of New York. The allegations against ACE concern the alleged bid rigging and contingent commission scheme as similarly alleged in the federal commercial insurance cases. Plaintiffs assert the following causes of action against ACE: breach of fiduciary duty, aiding and abetting breaches of fiduciary duties, unjust enrichment, conspiracy, and fraud. AIG appointed a Special Litigation Committee (SLC) to investigate these derivative cases. On June 13, 2007, in the AIG derivative case pending in Delaware Chancery Court, the SLC filed an amended complaint against certain defendants and a motion to terminate certain defendants. Neither ACE nor Evan G. Greenberg was named in either the amended complaint or the motion to terminate. The shareholder plaintiffs have taken the position that their complaint is still operative and proper against ACE, Evan G. Greenberg, and certain other defendants who were not named in the SLC’s amended complaint or motion to terminate. On July 6, 2007, ACE and Evan G. Greenberg each moved to dismiss the shareholders plaintiffs’ complaint. A new complaint was filed on September 28, 2007. The defendants will be filing motions to dismiss on November 9, 2007. The New York action is currently stayed.
In all of the above-referenced lawsuits, plaintiffs seek compensatory and in some cases special damages without specifying an amount. As a result, ACE cannot at this time estimate its potential costs related to these legal

matters and, accordingly, no liability for compensatory damages has been established in the consolidated financial statements.
ACE’s ultimate liability for these matters is not likely to have a material adverse effect on ACE’s consolidated financial condition, although it is possible that the effect could be material to ACE’s consolidated results of operations for an individual reporting period.
9. Taxation
The Company adopted the provisions of FIN 48 on January 1, 2007. As a result of the adoption of FIN 48, the Company recognized a reduction to opening retained earnings of $22 million. This cumulative effect of adopting FIN 48 is comprised of a $20 million increase in the liability for unrecognized tax benefits and a $2 million after-tax adjustment to interest payable. The Company’s total unrecognized tax benefit as of the adoption date was $196 million. Due primarily to a change in tax regulation during the first quarter, the Company decreased its liability for unrecognized tax benefits in the amount of $31 million during the three months ended March 31, 2007.
Included in the balance at January 1, 2007, are $5 million of unrecognized tax benefits for which the ultimate deductibility is highly certain but for which there is uncertainty about the timing of such deductibility. Because of the impact of deferred tax accounting, other than interest and penalties, an unfavorable resolution of these temporary items would not affect the annual effective tax rate but would accelerate the payment of cash to the taxing authority to an earlier period. Consequently, the total amount of unrecognized tax benefits as of January 1, 2007, that would affect the effective tax rate, if recognized, is $147 million. The total amount of unrecognized tax benefits as of January 1, 2007, that would reduce goodwill, if recognized, is $44 million.
The Company recognizes accruals for interest and penalties, if any, related to unrecognized tax benefits in Income tax expense. As of January 1, 2007, the Company has recorded $4 million in liabilities for tax related interest in its consolidated balance sheet.
The Internal Revenue Service has completed examinations of the Company’s federal tax returns for taxable years through 2001. The outcome of the examinations did not have a material effect on the Company’s financial condition or results of operations. The IRS completed its field examination of the Company’s federal tax returns for 2002, 2003, and 2004 during the three months ended September 30, 2007, and has proposed several adjustments principally involving transfer pricing and other insurance related tax deductions. The Company intends to dispute the proposed adjustments at the Appeals Division of the IRS. While it is reasonably possible that a significant increase or decrease in the Company’s unrecognized tax benefits could occur in the next twelve months, given the uncertainty regarding the timing and possible outcomes of the appeals process, a current estimate of the range of reasonably possible changes cannot be made. With few exceptions, the Company’s significant UK subsidiaries remain subject to examination for tax years 2004 and later.

 ITEM 2.	Management’s Discussion and Analysis of Financial Condition and Results of Operations	
The following is a discussion of our results of operations, financial condition, and liquidity and capital resources as of and for the three and nine months ended September 30, 2007. Our results of operations and cash flows for any interim period are not necessarily indicative of our results for the full year. This discussion should be read in conjunction with our Consolidated Financial Statements and related notes and our Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the year ended December 31, 2006.
The Private Securities Litigation Reform Act of 1995 provides a “safe harbor” for forward-looking statements. Any written or oral statements made by us or on our behalf may include forward-looking statements that reflect our current views with respect to future events and financial performance. These forward-looking statements are subject to certain risks, uncertainties, and assumptions about our business that could cause actual results to differ materially from such statements. These risks, uncertainties, and assumptions (which are described in more detail elsewhere herein and in other documents we file with the Securities and Exchange Commission (SEC)) include but are not limited to:
 
 	•	 	losses arising out of natural or man-made catastrophes such as hurricanes, typhoons, earthquakes, floods, hailstorms, windstorms, climate change, or terrorism which could be affected by:	
 
 	•	 	the number of insureds and ceding companies affected;	
 
 	•	 	the amount and timing of losses actually incurred and reported by insureds;	
 
 	•	 	the impact of these losses on our reinsurers and the amount and timing of reinsurance recoverables actually received;	
 
 	•	 	the cost of building materials and labor to reconstruct properties following a catastrophic event; and	
 
 	•	 	complex coverage and regulatory issues such as whether losses occurred from storm surge or flooding and related lawsuits;	
 
 	•	 	actions that rating agencies may take from time to time, such as changes in our claims-paying ability, financial strength, or credit ratings or placing these ratings on credit watch negative or the equivalent;	
 
 	•	 	global political conditions, the occurrence of any terrorist attacks, including any nuclear, radiological, biological, or chemical events, or the outbreak and effects of war, and possible business disruption or economic contraction that may result from such events;	
 
 	•	 	the ability to collect reinsurance recoverables, credit developments of reinsurers, and any delays with respect thereto and changes in the cost, quality, or availability of reinsurance;	
 
 	•	 	the occurrence of catastrophic events or other insured or reinsured events with a frequency or severity exceeding our estimates;	
 
 	•	 	actual loss experience from insured or reinsured events and the timing of claim payments;	
 
 	•	 	the uncertainties of the loss-reserving and claims-settlement processes, including the difficulties associated with large individual claims or catastrophe-oriented results, assessing environmental damage and asbestos-related latent injuries, the impact of aggregate-policy-coverage limits, and the impact of bankruptcy protection sought by various asbestos producers and other related businesses and the timing of loss payments;	
 
 	•	 	judicial decisions and rulings, new theories of liability, legal tactics, and settlement terms;	
 
 	•	 	the effects of public company bankruptcies and/or accounting restatements, as well as disclosures by and investigations of public companies relating to possible accounting irregularities, and other corporate governance issues, including the effects of such events on:	
 
 	•	 	the capital markets;	
 
28

Table of Contents

 	•	 	the markets for directors and officers (D&O) and errors and omissions (E&O) insurance; and	
 
 	•	 	claims and litigation arising out of such disclosures or practices by other companies;	
 
 	•	 	uncertainties relating to governmental, legislative, and regulatory policies, developments, actions, investigations, and treaties, which, among other things, could subject us to insurance regulation or taxation in additional jurisdictions or affect our current operations;	
 
 	•	 	the actual amount of new and renewal business, market acceptance of our products, and risks associated with the introduction of new products and services and entering new markets, including regulatory constraints on exit strategies;	
 
 	•	 	the competitive environment in which we operate, including trends in pricing or in policy terms and conditions, which may differ from our projections and changes in market conditions that could render our business strategies ineffective or obsolete;	
 
 	•	 	developments in global financial markets, including changes in interest rates, stock markets, and other financial markets, and foreign currency exchange rate fluctuations, which could affect our statement of operations, investment portfolio, and financing plans;	
 
 	•	 	the potential impact from government-mandated insurance coverage for acts of terrorism;	
 
 	•	 	the availability of borrowings and letters of credit under our credit facilities;	
 
 	•	 	changes in the distribution or placement of risks due to increased consolidation of insurance and reinsurance brokers;	
 
 	•	 	material differences between actual and expected assessments for guaranty funds and mandatory pooling arrangements;	
 
 	•	 	the effects of investigations into market practices in the property and casualty (P&C) industry;	
 
 	•	 	changing rates of inflation and other economic conditions;	
 
 	•	 	the amount of dividends received from subsidiaries;	
 
 	•	 	loss of the services of any of our executive officers without suitable replacements being recruited in a reasonable time frame;	
 
 	•	 	the ability of our technology resources to perform as anticipated; and	
 
 	•	 	management’s response to these factors and actual events (including, but not limited to, those described above).	
The words “believe”, “anticipate”, “estimate”, “project”, “should”, “plan”, “expect”, “intend”, “hope”, “will likely result” or “will continue”, and variations thereof and similar expressions, identify forward-looking statements. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of their dates.

Net premiums written, which reflect the premiums we retain after purchasing reinsurance protection, were stable in the three and nine months ended September 30, 2007, compared with the prior year periods. Net premiums written and earned were favorably impacted by weakness in the U.S. dollar relative to the euro and the pound sterling. Excluding the foreign exchange impact, net premiums written declined approximately three percent in the three and nine months ended September 30, 2007. Our net premiums written reflect growth in our worldwide retail business in the U.S. and internationally, offset by decreases in our wholesale business. We continue to experience growth in our accident and health business (A&H) internationally. We experienced declines in the U.S. wholesale lines and middle market workers’ compensation business. We also reported declines in our P&C reinsurance business due to competitive conditions and clients increasing their risk retentions. Overall, for the quarter ended September 30, 2007, excluding our life operations, net premiums written for our insurance business increased two percent, while our reinsurance business reported a decrease of 24 percent. In general, market conditions globally are competitive and, as a result, rate decreases have accelerated during the quarter ended September 30, 2007. Notwithstanding the difficult market conditions, our breadth of products, geography, and distribution allows us to take advantage of opportunities worldwide without sacrificing underwriting discipline and thereby to grow shareholders’ equity.

Net premiums earned reflect the portion of net premiums written that were recorded as revenues for the period as the exposure period expires. Net premiums earned for our P&C business increased one percent and four percent in the three and nine months ended September 30, 2007, respectively, compared with the prior year periods. These results reflect decreases in production at Global Reinsurance (property catastrophe and U.S. casualty) and wholesale business due to competitive conditions over the last year, offset by net premiums earned from a large assumed loss portfolio contract (written at ACE USA during the first quarter of 2007). Our life operations continue to experience growth in both life insurance and life reinsurance.
Net investment income increased 19 percent and 21 percent in the three and nine months ended September 30, 2007, compared with the prior year periods. The increase in net investment income was primarily due to positive operating cash flows, which have resulted in a higher overall average invested asset base, and the impact of the revised amortization of discounts or reduced premiums recorded for the debt securities resulting from other than temporary impairments in prior periods.
In evaluating our P&C business, we use the combined ratio, the loss and loss expense ratio, the policy acquisition cost ratio, and the administrative expense ratio. We calculate these ratios by dividing the respective expense amounts by net premiums earned. We do not calculate these ratios for the life business as we do not use these measures to monitor or manage that business. The combined ratio is determined by adding the loss and loss expense ratio, the policy acquisition cost ratio, and the administrative expense ratio. A combined ratio under 100 percent indicates underwriting income and a combined ratio exceeding 100 percent indicates underwriting losses.
The following table shows our consolidated loss and loss expense ratio, policy acquisition cost ratio, administrative expense ratio, and combined ratio for P&C business for the periods indicated.

We experienced net catastrophe losses of $21 million and $136 million in the three and nine months ended September 30, 2007, respectively. This compares with net catastrophe losses of $6 million and $11 million in the three and nine months ended September 30, 2006, respectively. The catastrophe losses incurred during the quarter ended September 30, 2007, were primarily related to U.K. floods and a hail storm in Canada. For the nine months ended September 30, 2007, net catastrophe losses were primarily related to floods in the U.K., Australia and the U.S. and also include the impact of European windstorm Kyrill.
Prior period development arises from changes to loss estimates recognized in the current year that relate to loss reserves first reported in previous calendar years and excludes the effect of losses from the development of earned premium from previous accident years. We experienced net favorable prior period development of $70 million and $128 million in the three and nine months ended September 30, 2007, respectively. For the nine months ended September 30, 2007, the $128 million includes favorable prior period development of $54 million on short-tail lines, as well as, favorable short-tailed specialty development of $20 million and $33 million on A&H and crop/hail, respectively. The three and nine months ended September 30, 2006, included net adverse prior period development of $17 million and net favorable prior period development of $29 million, respectively. The favorable prior period development in the quarter ended September 30, 2007, was the net result of several underlying favorable and adverse movements. Refer to “Prior Period Development” for more information. The remaining increase in the current quarter loss and loss expense ratio was primarily due to unfavorable current accident year experience at Insurance – Overseas General, due to competitive market conditions and declining prices. Further, the quarter ended September 30, 2006, benefited from unusually favorable experience, particularly on short-tail lines.
Our policy acquisition costs include commissions (i.e., commissions we pay on assumed business and commissions we receive on ceded business), premium taxes, underwriting, and other costs that vary with, and are primarily related to, the production of premium. Our policy acquisition cost ratio increased in the quarter ended September 30, 2007, compared with the prior year quarter, primarily due to changes in business mix, particularly the increase in A&H and crop/hail business. For the nine months ended September 30, 2007, the decrease in the policy acquisition cost ratio was a result of lower acquisition costs in the Global Reinsurance segment in the first half of 2007 and in the Insurance – North American segment in the quarter ended March 31, 2007 (refer to Global Reinsurance and Insurance – North American, below). Administrative expenses include all other operating costs. Administrative expenses for the nine months ended September 30, 2006, included $80 million related to the settlement with certain governmental agencies from their investigations of various insurance industry business practices.
Interest expense decreased in the quarter ended September 30, 2007, compared with the prior year quarter, due primarily to a decrease in average outstanding debt. In August of the prior year quarter we repaid $300 million, 8.3 percent notes.
Our effective income tax rate, which we calculate as income tax expense divided by income before income tax, was 17 percent and 18 percent in the three and nine months ended September 30, 2007, respectively. This compares with an effective income tax rate of 18 percent and 20 percent in the three and nine months ended September 30, 2006, respectively. The first quarter of 2007 included a decrease in the FIN 48 liability for unrecognized tax benefits in the amount of $31 million.

Insurance – North American
Insurance – North American experienced $4 million and $8 million of net adverse prior period development in the three and nine months ended September 30, 2007, respectively, compared with net adverse prior period development of $30 million and $45 million in the three and nine months ended September 30, 2006, respectively. The net prior period development for the quarter ended September 30, 2007, was the net result of several underlying adverse and favorable movements. The most significant items of adverse and favorable prior period development follow:
 
 	•	 	Adverse development of $13 million on long-tail business driven by the following principal changes:	
 
 	•	 	Adverse development on ACE USA long-tail lines due to a correction of a $21 million reconciliation error made in 2006 relating to incurred but not reported (IBNR) reserves.	
 
 	•	 	Adverse development of $20 million on ACE Bermuda long-tail professional lines mainly in report years 2001 and 2002 due to revised loss estimates for a number of existing claims that reflect the impact from potential litigation and arbitration following our reassessment of severity for several specific claims during the current quarter.	
 
 	•	 	Favorable development of $24 million on ACE Bermuda’s long-tail reinsurance book of business mainly in the 2001 accident year as a result of a settlement notification received in the current quarter that was favorable relative to held reserves.	
 
33

Table of Contents

 	•	 	Favorable development of $8 million on long-tail business in the 1997 accident year because of a correction for reserves on a large claim in ACE USA’s U.S. International portfolio.	
 
 	•	 	Favorable development of $9 million on short-tail and specialty business driven by the following principal changes:	
 
 	•	 	Adverse development on the 2005 accident year hurricanes in the amount of $34 million on short-tail ACE Westchester property ($10 million) and specialty inland marine covers ($11 million) and short-tail Financial Services finite reinsurance ($13 million). The changes in estimate were driven by developments in the current quarter on claims arising from a few excess policies that are expected to be settled soon for amounts in excess of our case reserves prompting an adjustment to our projection of ultimate losses during the quarter ended September 30, 2007. The claim handling associated with these hurricanes has involved complex and unique causation and coverage issues. These issues continue to be present and may have a further material adverse impact on our financial results.	
 
 	•	 	Favorable development of $21 million arising from ACE USA’s Global Underwriting Group short-tail property business, primarily for the 2004 through 2006 accident years. Approximately $12 million arose from closure of claims arising from 2004 hurricanes on a more favorable basis than the held reserves. The remaining development was driven by better than expected case incurred development in the 2005 and 2006 accident years relative to our prior estimates which relied more heavily upon loss ratio expectations used in booking initial results.	
 
 	•	 	Favorable development totaling $11 million on a number of short-tail (ACE Energy and ACE Westchester property) portfolios and specialty lines (ACE Westchester inland marine) portfolios, where claims emergence and development in the quarter and year to date for the 2006 accident year has been favorable relative to our prior projections.	
The net prior period development for the three months ended September 30, 2006, was the net result of several underlying favorable and adverse movements, the most significant of which follow:
 
 	•	 	Adverse development of $25 million on long-tail business driven by the following principal changes:	
 
 	•	 	Adverse development of $35 million on a run-off workers’ compensation portfolio relating to 1996 and prior accident years. This development was caused by a re-estimation of liabilities following higher than anticipated loss emergence.	
 
 	•	 	Net favorable development of $8 million on other workers’ compensation business primarily due to lower than expected loss emergence on large account business from 2004 and prior accident years.	
 
 	•	 	Adverse development of $38 million on property lines identified as part of our standard quarterly reserving process. This movement was primarily due to an increase in the estimate of ultimate losses on catastrophes from the 2005 accident year of $50 million. In contrast, there was favorable development of $13 million arising on non-catastrophe ultimate loss estimates, primarily for the 2005 accident year, following lower than anticipated loss emergence.	
 
 	•	 	Favorable development on specialty business of $33 million due to lower than expected loss emergence from the 2004 and 2005 accident years. The principal components of this movement were $14 million and $12 million on surety and aerospace business, respectively.	
Insurance – Overseas General
Insurance – Overseas General experienced $64 million and $116 million of net favorable prior period development in the three and nine months ended September 30, 2007, respectively, compared with net favorable prior period development of $16 million and $76 million in the three and nine months ended September 30, 2006,

respectively. The net prior period development for the quarter ended September 30, 2007, was the net result of several underlying favorable and adverse movements, the most significant of which follow:
 
 	•	 	Favorable development of $44 million primarily in the 2004 and prior accident years for ACE International long-tail casualty and financial lines. This favorable prior period development arose following our annual review of long-tail lines completed in the current quarter. The development was driven by a combination of favorable emergence versus expectations over the past year, and greater credibility being assigned to Bornhuetter-Ferguson projections versus expected loss ratio methods, a common reserve practice, as accident years mature.	
 
 	•	 	Adverse development of $12 million in ACE Global Markets long-tail professional lines, primarily in years of account 1999-2003. This adverse prior period development was driven largely by reserve strengthening for one account and revised assumptions regarding reinsurance recoveries on two other accounts.	
 
 	•	 	Favorable development of $15 million on short-tail property and fire lines primarily in the 2005 and 2006 accident years in ACE International and years 2005 and prior in ACE Global Markets. The favorable development in the current quarter was primarily from the 2005 and 2006 accident years and was driven by lower than anticipated frequency and severity of late reported claim emergence during the quarter and favorable development and settlement of several previously reported large losses.	
 
 	•	 	Favorable development of $18 million on specialty business driven by the following principal changes:	
 
 	•	 	Favorable development of $14 million in specialty A&H primarily in the 2005 and 2006 accident years in Europe. This favorable prior period development followed the completion of our quarterly reserve analysis and was driven by better than expected loss experience relative to prior reserving assumptions. The favorable experience arose in direct marketing A&H businesses across several countries with no particular underlying claim or loss emergence trend identifiable.	
 
 	•	 	Favorable development of $11 million in specialty marine, primarily in the 2005 and 2006 accident years in both ACE International and ACE Global Markets. This favorable prior period development was largely driven by case reserve reductions booked by the claims department during the quarter ended September 30, 2007, as new information on the claims became available.	
 
 	•	 	Adverse development of $9 million in specialty consumer lines, primarily in the 2000-2006 accident years in ACE International. This adverse development was largely driven by continuing deterioration of homeowner’s warranty business. The adverse development in the current quarter was primarily driven by higher than anticipated development on several key claim metrics underlying the reserve estimate; number of reopened claims, loss adjustment expenses and frequency and severity of late reported claims.	
The net prior period development for the quarter ended September 30, 2006, was the net result of several underlying favorable and adverse movements, the most significant of which follow:
 
 	•	 	Favorable development of $22 million on short-tail lines from the 2004 and 2005 accident years. This movement can be attributed to better than expected loss emergence on both the ACE International and ACE Global Markets property books.	
 
 	•	 	Adverse development of $6 million on specialty and long-tail business including aviation, A&H, marine, and political risk. This net movement was the result of a number of adverse and favorable movements across a variety of business areas. The main underlying movements were:	
 
 	•	 	Adverse development of $17 million on aviation business due to high case-incurred activity on a small number of claims from 1999 and prior years, and reassessment of the ceded reserves from the 2001 and 2002 years.	
 
 	•	 	Favorable development of $9 million on A&H business as a result of lower than expected loss emergence from the 2004 and 2005 accident years.

Global Reinsurance
Global Reinsurance experienced $10 million and $20 million of net favorable prior period development in the three and nine months ended September 30, 2007, respectively, compared with net adverse prior period development of $3 million and $2 million in the three and nine months ended September 30, 2006, respectively. The net prior period development for the quarter ended September 30, 2007, was the net result of several underlying favorable and adverse movements:
 
 	•	 	The largest favorable movements were related to short-tail and specialty lines totaling $12 million. These movements were due to an aggregation of favorable developments across several accident years (primarily 2004-2006) on a number of lines of business in Europe and Bermuda. The favorable development arose from less than expected claims emergence.	
 
 	•	 	The largest adverse movement was $2 million for long-tail business in the 2002 treaty year due to worse than expected claims development over the last few quarters.	
The net prior period development for the quarter ended September 30, 2006, was the net result of several underlying favorable and adverse movements. These movements were identified as part of our standard quarterly reserving process and were generally in the order of $1 million to $3 million across a wide range of business areas, mostly relating to short-tail exposures.
Segment Operating Results – Three and Nine Months Ended September 30, 2007 and 2006
The discussions that follow include tables that present segment operating results for the three and nine months ended September 30, 2007 and 2006. In presenting our segment operating results, we have discussed our performance with reference to underwriting results, which is not a measure under generally accepted accounting principles in the U.S. (GAAP). We consider this measure, which may be defined differently by other companies, to be important in understanding our overall results of operations. Underwriting results are calculated by subtracting losses and loss expenses, life and annuity benefits, policy acquisition costs, and administrative expenses from net premiums earned. We use underwriting results and operating ratios to monitor the results of our operations without the impact of certain factors, including net investment income, other (income) expense, interest expense, income tax expense, and net realized gains (losses). We believe the use of this measure enhances the understanding of our results of operations by highlighting the underlying profitability of our insurance business. Underwriting results should not be viewed as a substitute for measures determined in accordance with GAAP.
Our business consists of the following segments: Insurance – North American, Insurance – Overseas General, Global Reinsurance, and Life Insurance and Reinsurance. For more information, refer to “Segment Information” included under Item 1 of our Annual Report on Form 10-K for the year ended December 31, 2006.

Net premiums written for the Insurance – North American segment were stable in the three and nine months ended September 30, 2007, compared with the prior year periods. ACE USA, the U.S.-based retail division, reported modest growth for the quarter ended September 30, 2007, primarily driven by increased production in the specialty casualty and energy lines on the strength of higher customer retention rates and the expansion of our business by taking advantage of our full-service local presence nationally. For the nine months ended September 30, 2007, ACE USA’s net premiums written growth was primarily driven by continued growth in specialty casualty and energy lines, as well as, a large assumed loss portfolio contract written during the first quarter of 2007. These increases were partially offset by our decision to curtail middle market workers’ compensation writings in response to unfavorable market conditions. ACE Westchester, the wholesale operation, reported a decrease in net premiums written for the three and nine months ended September 30, 2007, primarily due to lower P&C net premiums written reflecting competitive market conditions and rate decreases, as well as, lower retention of gross premiums written, caused by changes in mix of business. This was partially offset by increased crop/hail writings during the current quarter, primarily reflecting higher commodity prices for certain crops. ACE Bermuda reported decreases in net premiums written for the quarter ended September 30, 2007, primarily due to a decline in professional lines business. For the nine month period, ACE Bermuda’s decline was primarily a result of the prior year period having included residual activity on expiring structured property catastrophe contracts. ACE USA writes assumed loss portfolio contracts which are typically low in volume and large in monetary value and can be material with respect to a period’s operating results. Premiums written associated with these transactions in any one period are not necessarily indicative of premiums to be written in future periods. ACE Bermuda no longer writes these contracts.

ACE USA’s net premiums earned increased 5 percent and 14 percent in the three and nine months ended September 30, 2007, respectively, compared with the prior year periods. The increases were primarily driven by the assumed loss portfolio contract noted above, as well as new business in the energy unit, and growth in specialty casualty lines including professional risk, umbrella excess, custom casualty, and environmental. ACE USA’s curtailment of middle market workers’ compensation business partially offset these increases. ACE Westchester’s net premiums earned increased three percent and one percent in the three and nine months ended September 30, 2007, compared with the prior year periods. This growth was primarily from increased crop/hail production due to higher commodity prices, partially offset by weakness in P&C lines due to competitive market conditions. ACE Bermuda’s net premiums earned decreased 10 percent and 15 percent in the three and nine months ended September 30, 2007, respectively, compared with the prior year periods, primarily due to a decrease in assumed loss portfolio business as well as professional risk and excess liability.
Insurance – North American’s reported loss and loss expense ratio was stable in the three and nine months ended September 30, 2007, compared with the prior year periods.

Insurance – North American recorded net catastrophe losses of $nil and $16 million in the three and nine months ended September 30, 2007, compared with $nil in the prior year periods. The catastrophe losses incurred during the nine months ended September 30, 2007, were primarily related to U.S. floods. Insurance – North American incurred net adverse prior period development of $4 million and $8 million in the three and nine months ended September 30, 2007. This compares with net unfavorable prior period development of $30 million and $45 million in the three and nine months ended September 30, 2006, respectively. Refer to “Prior Period

Development” for more detail. The loss and loss expense ratio for the nine months ended September 30, 2007, was also impacted by the aforementioned assumed loss portfolio contract, which was written at a higher loss ratio compared with other types of business.
Insurance – North American’s policy acquisition cost ratio increased in the quarter ended September 30, 2007, compared with the prior year quarter. This increase was a result of higher commission costs due to changes in business mix, particularly the increased crop/hail business at ACE Westchester which incurs higher net commission rates than other types of business. For the nine months ended September 30, 2007, the decrease was primarily related to reductions in policy acquisition costs at ACE USA and ACE Westchester. For ACE USA, the decline reflects lower net commission costs due to higher ceding commissions, as well as lower premium taxes due to reassessment of obligations for premium-based assessments and guaranty funds. In addition, the assumed loss portfolio transfer contract, noted above, incurred low acquisition costs, which is typical for these transactions. For ACE Westchester, the decline in the policy acquisition cost ratio was primarily due to lower profit share commissions on crop business in the nine months ended September 30, 2007, compared with the prior year period.
Administrative expenses were stable in quarter ended September 30, 2007, compared with the prior year quarter. For the nine months ended September 30, 2007, administrative expenses increased primarily due to increased staffing costs at ACE USA, as well as lower net profits for ACE USA’s ESIS operation (third party claim services), which we include in administrative expenses. In addition, administrative expenses for ACE USA for the nine months ended September 30, 2006, were favorably impacted by recoveries relating to amounts previously written off.

Insurance – Overseas General’s net premiums written increased six percent in the three and nine months ended September 30, 2007, compared with the prior year periods. Foreign exchange impact on ACE International’s results accounted for most of this increase as both the euro and the pound sterling strengthened significantly relative to the U.S. dollar during the first nine months of 2007. ACE International continues to experience growth in its A&H customer base in virtually all of its regions of operation, partially offset by decreased P&C volume due to competitive conditions in the U.K., Asia Pacific, and Latin America. ACE Global Markets reported increased reinsurance costs combined with rate decreases due to competition in aviation and property, partially offset by increased production in political risk and A&H lines. The wholesale market has softened more than the retail market and the decrease in production is reflective of this – we are declining business, both new and renewal, that does not meet our underwriting standards.

Insurance – Overseas General’s net premiums earned increased four percent and five percent in the three and nine months ended September 30, 2007, respectively, compared with the prior year periods, primarily due to the impact of foreign exchange. This segment continues to grow its A&H business which has offset weak market conditions for U.K. and Asia Pacific P&C business, and higher reinsurance costs for certain lines. ACE International’s net premiums earned increased eight percent and nine percent in the three and nine months ended September 30, 2007, respectively, compared with the prior year periods, primarily due to the impact of foreign exchange. For ACE Europe, competition for P&C business in the U.K. has resulted in lower rates as well as unfavorable terms and conditions, while A&H business has increased. ACE Asia Pacific and ACE Latin America reported increases in net premiums earned primarily driven by solid growth in A&H business. These regions have been successfully utilizing unique and innovative distribution channels to grow their A&H customer base. ACE Global Markets’ net premiums earned decreased nine percent and five percent in the three and nine months ended September 30, 2007, respectively, compared with the prior year periods, primarily due to decreased production, higher reinsurance costs, and changes in business mix (growth of energy lines, which earns slower than other types of business).

Insurance – Overseas General recorded net catastrophe losses of $8 million and $81 million in the three and nine months ended September 30, 2007, respectively, compared with $3 million in the prior year periods. For the nine months ended September 30, 2007, net catastrophe losses were related to floods in the U.K. and Australia and European windstorm Kyrill. Insurance – Overseas General experienced net favorable prior period development of $64 million and $116 million in the three and nine months ended September 30, 2007, respectively, compared with net favorable prior period development of $16 million and $76 million, respectively, in the prior year periods. Refer to “Prior Period Development” for more detail. The remaining increase to the current quarter loss and loss expense ratio was primarily due to unfavorable current accident year experience at ACE International and ACE Global Markets, primarily due to competitive market conditions and declining prices. Further, the quarter ended September 30, 2006, benefited from unusually favorable experience, particularly on short-tail lines.
Insurance – Overseas General’s policy acquisition cost ratio increased due to the continued growth of A&H business, which generally incurs higher acquisition costs relative to other types of business. This impact on the segment’s policy acquisition costs was tempered by increased ceding commissions on political, financial, and energy lines at ACE Global Markets. Insurance – Overseas General’s administrative expenses increased in the three and nine months ended September 30, 2007, compared with the prior year periods, primarily due to the impact of foreign exchange. Additionally, ACE International reported increased costs associated with its entrance into emerging markets, specifically Eastern Europe and the Middle East, and spending in support of A&H growth at Asia Pacific.

Global Reinsurance’s net premiums written decreased 24 percent and 21 percent in the three and nine months ended September 30, 2007, respectively, compared with the prior year periods. For the three and nine months ended September 30, 2007, Global Reinsurance reported decreased net premiums written due to declines in production as a result of intensely competitive conditions across all of its regions of operation. Additionally, our net retention ratio was lower in the current periods as we purchased retrocessional cover in the quarter ended September 30, 2007.

Global Reinsurance’s net premiums earned decreased 14 percent and 13 percent in the three and nine months ended September 30, 2007, respectively, compared with the prior year periods. The decrease in net premiums earned was due to the decline in overall production in the nine months ended September 30, 2007. ACE Tempest Re USA’s reported decline resulted from reductions in quota-share net premiums written in 2006 and through the first nine months of 2007. ACE Tempest Re Canada commenced writing business in 2007.
The following table shows the impact of catastrophe losses and prior period development on our reported loss and loss expense ratio for the periods indicated.

Global Reinsurance reported $13 million and $39 million of net catastrophe losses in the three and nine months ended September 30, 2007, respectively. This compares with net catastrophe losses of $3 million and $8 million in the three and nine months ended September 30, 2006, respectively. The catastrophe losses incurred during the quarter ended September 30, 2007, were primarily related to U.K. floods and a hail storm in Canada. For the nine months ended September 30, 2007, net catastrophe losses were primarily related to European windstorm Kyrill. Global Reinsurance incurred net favorable prior period development of $10 million and $20 million in the three and nine months ended September 30, 2007, respectively. This compares with net adverse prior period development of $3 million and $2 million in the three and nine months ended September 30, 2006, respectively. Refer to “Prior Period Development” for more detail. The remaining increase in the loss and loss expense ratio was primarily due to changes in business mix.
The policy acquisition cost ratio was stable in the three and nine months ended September 30, 2007, primarily due to changes in our mix of business as well as lower ceding commissions, mainly during the first half of 2007. The administrative expense ratio decreased during the nine months ended September 30, 2007, due to a decline in advertising costs and number of staff.

Life Insurance and Reinsurance
Life Insurance and Reinsurance includes the operations of ACE Tempest Life Re (ACE Life Re) and ACE International Life (ACE Life). We assess the performance of our life insurance and reinsurance business based on life underwriting income which includes net investment income.

Life underwriting income increased in the three and nine months ended September 30, 2007, compared with the prior year periods, primarily due to the continued profitability of the Bermuda-based non-traditional reinsurance business for which there has been an increase in net premiums earned from a few large in-force treaties. Additionally, we have experienced a decline in underwriting losses at ACE Life and the U.S.-based traditional life reinsurance business due to premium growth during their early development. Life Insurance and Reinsurance’s administrative expenses increased primarily due to increased expenses to support business development opportunities at ACE Life and the U.S.-based traditional life reinsurance business, which was launched in 2006. Net realized gains (losses) consist of market value movement on the investment portfolio and fair value movement on guaranteed minimum income benefits (GMIBs), which occur due to changes in the level and volatility of interest rates and equity markets. For more information on minimum benefit guarantees under annuity contracts,  refer to Note 8 c) to the Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2006.

Net investment income is influenced by a number of factors including the amounts and timing of inward and outward cash flows, the level of interest rates, and changes in overall asset allocation. Net investment income increased 19 percent and 21 percent in the three and nine months ended September 30, 2007, respectively,

Table of Contents
compared with the prior year periods. The increase in net investment income was primarily due to positive operating cash flows which have resulted in a higher overall average invested asset base and the impact of the revised amortization of discounts or reduced premiums recorded for the debt securities resulting from other than temporary impairments in prior periods. The investment portfolio’s average market yield on fixed maturities was 5.5 percent and 5.4 percent at September 30, 2007 and 2006, respectively.
Net Realized Gains (Losses)
We take a long-term view with our investment strategy and our investment managers manage our investment portfolio to maximize total return within certain specific guidelines designed to minimize risk. The majority of our investment portfolio is available for sale and reported at fair value. Our held to maturity investment portfolio is reported at amortized cost.
The effect of market movements on our available for sale investment portfolio impacts net income (through net realized gains (losses)) when securities are sold or when “other-than-temporary” impairments are recorded on invested assets. Additionally, net income is impacted through the reporting of changes in the fair value of derivatives, including financial futures, options, swaps, GMIB reinsurance, and credit-default swaps. Changes in unrealized appreciation and depreciation on available for sale securities, which result from the revaluation of securities held, are reported as a separate component of accumulated other comprehensive income in shareholders’ equity.
The following table presents our pre-tax net realized gains (losses) for the periods indicated.

For a sensitivity discussion of the effect of changes in interest rates and equity indices on the fair value of derivatives and the resulting impact on our net income, refer to Item 7A of our Annual Report on Form 10-K for the year ended December 31, 2006.
We regularly review our investment portfolio for possible impairment based on criteria including economic conditions, credit loss experience, and issuer-specific developments. If there is a decline in a security’s net realizable value, we must determine whether that decline is “temporary” or “other-than-temporary”. The process of determining whether a decline in value is “temporary” or “other-than-temporary” requires considerable judgment and differs depending on whether or not the security is traded on a public market as well as by type of security. We review all of our fixed maturities and equity securities for potential impairment each quarter. Note 6 a) to the Consolidated Financial Statements for the quarter ended September 30, 2007, includes a table which summarizes all of our securities in an unrealized loss position at September 30, 2007. Refer to Note 7 e) to the Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2006, for criteria we consider in assessing potential impairment.

Our net realized gains (losses) in the three and nine months ended September 30, 2007, included losses of $18 million and $72 million, respectively, as a result of conditions which caused us to conclude that the decline in fair value was “other-than-temporary”. For the three and nine months ended September 30, 2006, these losses amounted to  $109 million and $201 million, respectively. A breakdown of “other-than-temporary” impairments is included in Note 6 b).

For the three and nine months ended September 30, 2007, equity in net (income) loss of partially-owned companies included our equity in the net loss of Assured Guaranty of $36 million and $10 million, respectively. This was primarily due to unrealized losses in Assured Guaranty’s credit derivatives portfolio of $49 million in the current quarter, which were reported as realized losses by Assured Guaranty. The impact to ACE of any potential financial guaranty losses incurred by Assured Guaranty are limited to our equity investment, which had a carrying value of $445 million at September 30, 2007. We have no reinsurance agreements with Assured Guaranty that cover financial guaranty exposures. Other expense items include certain federal excise taxes incurred as a result of capital management initiatives. These transactions are considered capital in nature and are excluded from underwriting results.
Investments
Our investment portfolio is invested primarily in fixed income securities with an average credit quality of AA as rated by the independent investment rating service Standard and Poor’s (S&P). The portfolio is externally managed by independent, professional investment managers. The average duration of our fixed income securities, including the effect of options and swaps, was 3.6 years at September 30, 2007, and 3.3 years at December 31, 2006. We estimate that a 100 basis point increase in interest rates would reduce our book value by approximately $1.3 billion at September 30, 2007. Our “other investments” principally comprise direct investments, investment funds, and limited partnerships. Our exposure to sub-prime mortgages is $272 million, which represents less than one percent of our investment portfolio. We hold no collateralized debt obligations in the portfolio. The sub-prime mortgage portfolio is broadly diversified and has a duration of approximately two years.
The following table shows the fair value and cost/amortized cost of our invested assets at September 30, 2007, and December 31, 2006.

Table of Contents
We evaluate the financial condition of our reinsurers and potential reinsurers on a regular basis and also monitor concentrations of credit risk with reinsurers. The provision for uncollectible reinsurance is required principally due to the failure of reinsurers to indemnify us, primarily because of disputes under reinsurance contracts and insolvencies. Provisions have been established for amounts estimated to be uncollectible.
Unpaid Losses and Loss Expenses
We establish reserves for the estimated unpaid ultimate liability for losses and loss expenses under the terms of our policies and agreements. These reserves take into account estimates both for claims that have been reported and for incurred but not reported (IBNR) and include estimates of expenses associated with processing and settling claims. The table below presents a roll forward of our gross and net unpaid losses and loss expenses for the period ended September 30, 2007.

The process of establishing reserves for claims can be complex and is subject to considerable variability as it requires the use of informed estimates and judgments. Our estimates and judgments may be revised as additional experience and other data become available and are reviewed, as new or improved methodologies are developed, or as current laws change. The following table shows our total reserves segregated between case reserves and IBNR reserves at September 30, 2007 and December 31, 2006.

Asbestos and Environmental (A&E) and Other Run-off Liabilities
Due to timing constraints associated with statutory reporting, this section is presented on a one quarter lag basis.
Included in our liabilities for losses and loss expenses are amounts for A&E. These A&E liabilities principally relate to claims arising from bodily-injury claims related to asbestos products and remediation costs associated with hazardous waste sites. The estimation of these liabilities is particularly sensitive to future changes in the legal, social, and economic environment. We have not assumed any such future changes in setting the value of our A&E reserves, which include provisions for both reported and IBNR claims.
Our exposure to A&E claims principally arises out of liabilities acquired when we purchased Westchester Specialty in 1998 and the P&C business of CIGNA in 1999, with the larger exposure contained within the liabilities acquired in the CIGNA transaction. In 1996, prior to our acquisition of the P&C business of CIGNA, the Pennsylvania Insurance Commissioner approved a plan to restructure INA Financial Corporation and its subsidiaries (the Restructuring) which included the division of Insurance Company of North America (INA) into two separate corporations: (1) an active insurance company that retained the INA name and continued to write P&C business and (2) an inactive run-off company, now called Century Indemnity Company (Century). As a

result of the division, predominantly all A&E and certain other liabilities of INA were allocated to Century and extinguished, as a matter of Pennsylvania law, as liabilities of INA. As part of the Restructuring, most A&E liabilities of various U.S. affiliates of INA were reinsured to Century, and Century and certain other run-off companies having A&E and other liabilities were contributed to Brandywine Holdings. As part of the 1999 acquisition of the P&C business of CIGNA, we acquired Brandywine Holdings and its various subsidiaries. For more information refer to “Brandywine Run-Off Entities” below.
The table below presents a roll forward of our consolidated A&E loss reserves, allocated and unallocated loss expense reserves for A&E exposures, and the provision for uncollectible reinsurance for the period ended June 30, 2007.

The A&E net loss reserves including allocated and unallocated loss expense reserves and provision for uncollectible reinsurance at June 30, 2007, of $1.963 billion shown in the above table are comprised of $1.403 billion in reserves held by Brandywine run-off companies, $221 million of reserves held by Westchester Specialty, $171 million of reserves held by ACE Bermuda, $147 million of reserves held by Insurance – Overseas General, and $21 million of reserves held by active ACE USA companies.
The net figures in the above table reflect third-party reinsurance other than reinsurance provided by the National Indemnity Company (NICO) under three aggregate excess of loss contracts described below (collectively, the NICO contracts). We exclude the NICO contracts as they cover non-A&E liabilities as well as A&E liabilities. The split of coverage provided under the NICO contracts for A&E liabilities as compared to non-A&E liabilities is entirely dependant on the timing of the payment of the related claims. Our ability to make an estimate of this split is not practicable. We believe, instead, that the A&E discussion is best provided excluding the NICO contracts, while separately discussing the NICO contracts in relation to the total subject business, both A&E and non-A&E, covered by those contracts. With certain exceptions, the NICO contracts provide coverage for our net A&E incurred losses and allocated loss expenses within the limits of coverage and above ACE’s retention levels. These exceptions include losses arising from certain operations of Insurance – Overseas General and participations by ACE Bermuda as a co-reinsurer or retrocessionaire in the NICO contracts.
Brandywine Run-off – Impact of NICO Contracts on ACE’s Run-off Liabilities
As part of the acquisition of CIGNA’s P&C business, NICO provided $2.5 billion of reinsurance protection to Century on all Brandywine loss and allocated loss adjustment expense reserves and on the A&E reserves of various ACE INA insurance subsidiaries reinsured by Century (in each case, including uncollectible reinsurance). The benefits of this NICO contract (the “Brandywine NICO Agreement”) flow to the other Brandywine companies and to the ACE INA insurance subsidiaries through agreements between those companies and Century. The Brandywine NICO Agreement was exhausted on an incurred basis in the fourth quarter of 2002.

(3) 	The balance at December 31, 2006, has been adjusted by $104 million to reflect a change in reporting to an incurred basis from a cash-received basis.	
Reserve Reviews
During 2006, we conducted an internal, ground-up review of our consolidated A&E liabilities as of June 30, 2006. As a result of the internal review, we concluded that our net loss reserves for the Brandywine operations, including A&E, were adequate and, therefore, no change to the carried net reserve was required, while the gross loss reserves increased by approximately $210 million. During the same period as we conducted our internal review, a team of external actuaries performed an evaluation as to the adequacy of the reserves of Century. This external review was conducted in accordance with the Brandywine Restructuring Order, which requires that an external actuarial review of Century’s reserves be completed every two years. The results of the external review were addressed with the Pennsylvania Insurance Department and no changes to statutory-basis loss reserves were deemed necessary. Our A&E reserves are not discounted and do not reflect any anticipated future changes in the legal, social, or economic environment, or any benefit from future legislative reforms.
Westchester Specialty – Impact of NICO Contracts on ACE’s Run-off Liabilities
As part of the acquisition of Westchester Specialty in 1998, NICO provided a 75 percent pro-rata share of $1 billion of reinsurance protection on losses and loss adjustment expenses incurred on or before December 31, 1996, in excess of a retention of $721 million (the 1998 NICO Agreement). NICO has also provided an 85 percent pro-rata share of $150 million of reinsurance protection on losses and allocated loss adjustment expenses incurred on or before December 31, 1992, in excess of a retention of $755 million (the 1992 NICO Agreement). At June 30, 2007, the remaining unused incurred limit under the 1998 NICO Agreement was $487 million, which is only available for losses and loss adjustment expenses. The 1992 NICO Agreement is exhausted on an incurred basis.

Reserving Considerations
For asbestos, we face claims relating to policies issued to manufacturers, distributors, installers, and other parties in the chain of commerce for asbestos and products containing asbestos. Claims can be filed by individual claimants or groups of claimants with the potential for hundreds of individual claimants at one time. Claimants will generally allege damages across an extended time period which may coincide with multiple policies for a single insured. Environmental claims present exposure for remediation and defense costs associated with the contamination of property as a result of pollution. It is common, especially for larger defendants, to be named as a potentially responsible party at multiple sites.
Brandywine Run-off Entities
In addition to housing a significant portion of our A&E exposure, the Brandywine operations include run-off liabilities related to various insurance and reinsurance businesses. The following companies comprise ACE’s Brandywine operations: Century (a Pennsylvania insurer), Century Re (a Pennsylvania insurer), and Century International Reinsurance Company Ltd. (a Bermuda insurer (CIRC)). All of the Brandywine companies are direct or indirect subsidiaries of Brandywine Holdings.
The U.S.-based ACE INA companies assumed two contractual obligations in respect of the Brandywine operations in connection with the Restructuring: a dividend retention fund obligation and a surplus maintenance obligation in the form of an aggregate excess of loss reinsurance agreement. In accordance with the Brandywine restructuring order, INA Financial Corporation established and funded a dividend retention fund (the Dividend Retention Fund) consisting of $50 million plus investment earnings. The full balance of the Dividend Retention Fund was contributed to Century as of December 31, 2002. To the extent future dividends are paid by INA Holdings Corporation to its parent, INA Financial Corporation, and to the extent INA Financial Corporation then pays such dividends to INA Corporation, a portion of those dividends must be withheld to replenish the principal of the Dividend Retention Fund to $50 million within five years. In the six months ended June 30, 2007, and in 2006, 2005, and 2004, no such dividends were paid and therefore, no replenishment of the Dividend Retention Fund occurred. The obligation to maintain and to replenish the Dividend Retention Fund as necessary and to the extent dividends are paid is ongoing until ACE INA receives prior written approval from the Pennsylvania Insurance Commissioner to terminate the fund.
In addition, an ACE INA insurance subsidiary provided reinsurance coverage to Century in the amount of $800 million under an aggregate excess of loss reinsurance agreement (the Aggregate Excess of Loss Agreement) if

Table of Contents
the statutory capital and surplus of Century falls below $25 million or if Century lacks liquid assets with which to pay claims as they become due, after giving effect to the contribution of the balance, if any, of the Dividend Retention Fund. Coverage under the Aggregate Excess of Loss Agreement was triggered as of December 31, 2002, following contribution of the balance of the Dividend Retention Fund, because Century’s capital and surplus fell below $25 million at December 31, 2002.
Effective December 31, 2004, ACE INA Holdings contributed $100 million to Century in exchange for a surplus note. After giving effect to the contribution and issuance of the surplus note, the statutory surplus of Century at June 30, 2007, was $25 million and approximately $345 million in statutory-basis losses were ceded to the Aggregate Excess of Loss Agreement. Century reports the amount ceded under the Aggregate Excess of Loss Agreement in accordance with statutory accounting principles, which differ from GAAP by, among other things, allowing Century to discount its asbestos and environmental reserves. For GAAP reporting purposes, intercompany reinsurance recoverables related to the Aggregate Excess of Loss Agreement are eliminated upon consolidation. To estimate ACE’s remaining claim exposure under the Aggregate Excess of Loss Agreement on a GAAP basis, we adjust the statutory cession to exclude the discount embedded in statutory loss reserves and we adjust the statutory provision for uncollectible reinsurance to a GAAP basis amount. At June 30, 2007, approximately $544 million in GAAP basis losses were ceded under the Aggregate Excess of Loss Agreement, leaving a remaining limit of coverage under that agreement of approximately $256 million. At December 31, 2006, the remaining limit of coverage under the agreement was $255 million. While we believe ACE has no legal obligation to fund losses above the Aggregate Excess of Loss Agreement limit of coverage, ACE’s consolidated results would nevertheless continue to include any losses above the limit of coverage for so long as the Brandywine companies remain consolidated subsidiaries of ACE.
Uncertainties Relating to ACE’s Ultimate Brandywine Exposure
In addition to the Dividend Retention Fund and Aggregate Excess of Loss Agreement commitments described above, certain ACE entities are primarily liable for asbestos, environmental, and other exposures that they have reinsured to Century. Accordingly, if Century were to become insolvent and ACE were to lose control of Century, some or all of the recoverables due to these ACE companies from Century could become uncollectible, yet those ACE entities would continue to be responsible to pay claims to their insureds or reinsureds. Under such circumstances, ACE would recognize a loss in its consolidated statement of operations. As of June 30, 2007, the aggregate reinsurance balances ceded by the active ACE companies to Century were approximately $1.5 billion. At June 30, 2007, Century’s carried gross reserves (including reserves ceded by the active ACE companies to Century) were $3.8 billion. We believe the intercompany reinsurance recoverables, which relate to liabilities payable over many years (i.e., 25 years or more), are not impaired at this time. A substantial portion of the liabilities ceded to Century by its affiliates have in turn been ceded by Century to NICO and, as of June 30, 2007, approximately $1.7 billion of cover remains on a paid basis. Should Century’s loss reserves experience adverse development in the future and should Century be placed into rehabilitation or liquidation, the reinsurance recoverables due from Century to its affiliates would be payable only after the payment in full of certain expenses and liabilities, including administrative expenses and direct policy liabilities. Thus, the intercompany reinsurance recoverables would be at risk to the extent of the shortage of assets remaining to pay these recoverables. As of June 30, 2007, losses ceded by Century to the active ACE companies and other amounts owed to Century by the active ACE companies were approximately $614 million in the aggregate.
Catastrophe Management
We continue to closely monitor our catastrophe accumulation around the world and have significantly reduced our U.S. wind exposure since 2005. Our modeled annual aggregate 1 in 100 year return period U.S. hurricane probable maximum loss, net of reinsurance is approximately $974 million; i.e., there is a one percent chance that ACE’s losses incurred in any year from U.S. hurricanes could be in excess of $974 million (or approximately six percent of our total shareholders’ equity at September 30, 2007). We estimate that at such loss levels, aggregate industry losses are approximately $128 billion. If the 2005 hurricanes were to recur, our net losses on an “as-if”

Table of Contents
basis would be 30 percent lower. ACE’s modeled losses reflect our in-force portfolio and catastrophe reinsurance program as of July 1, 2007. The modeling estimates of both ACE and industry loss levels are inherently uncertain owing to key assumptions. First, while the use of third-party catastrophe modeling packages to simulate hurricane losses is prevalent within the insurance industry, the models are reliant upon significant meteorology and engineering assumptions to estimate hurricane losses. In particular, modeled hurricane events are not always a representation of actual events and ensuing additional loss potential. Second, there is no universal standard in the preparation of insured data for use in the models and the running of the modeling software. Third, we are reliant upon third-party estimates of industry insured exposures and there is significant variation possible around the relationship between ACE’s loss and that of the industry following an event. Fourth, we assume that our reinsurance recoveries following an event are fully collectible. These loss estimates do not represent ACE’s potential maximum exposures and it is highly likely that ACE’s actual incurred losses would vary materially from the modeled estimates.
Liquidity
The payments of dividends or other statutorily permissible distributions from our operating companies are subject to the laws and regulations applicable to each jurisdiction, the need to maintain capital levels adequate to support the insurance and reinsurance operations, as well as financial strength ratings issued by independent rating agencies. During the nine months ended September 30, 2007, we were able to meet all of our obligations, including the payment of dividends declared on our Ordinary Shares and Preferred Shares, with our net cash flows and dividends received. We anticipate that positive cash flows from operations (underwriting activities and investment income) should be sufficient to cover cash outflows under most loss scenarios through 2007. Should the need arise, we generally have access to the capital markets and other available credit facilities. At September 30, 2007, our available credit lines totaled $2.8 billion, and usage was $1.6 billion. Based on our projected requirements for bank credit facilities, we are currently refinancing our letter of credit facilities and our revolving credit facility. It is currently anticipated that our $500 million secured letter of credit facility will be cancelled and our $1 billion unsecured letter of credit facility will be renewed for a further five years. It is currently anticipated that our revolving credit facility will be reduced from $600 million to $500 million and will also be renewed for a further five years.
We assess which subsidiaries to draw dividends from based on a number of factors. Considerations such as regulatory and legal restrictions as well as the subsidiary’s financial condition are paramount to the dividend decision. The legal restrictions on the payment of dividends from retained earnings by our Bermuda subsidiaries are currently satisfied by the share capital and additional paid-in capital of each of the Bermuda subsidiaries. During the nine months ended September 30, 2007 and 2006, ACE Bermuda declared and paid dividends of $168 million and $426 million, respectively. We expect that a majority of our cash inflows for the remainder of 2007 will be from our Bermuda subsidiaries.
The payment of any dividends from ACE Global Markets or its subsidiaries is subject to applicable U.K. insurance laws and regulations. In addition, the release of funds by Syndicate 2488 to subsidiaries of ACE Global Markets is subject to regulations promulgated by the Society of Lloyd’s. ACE INA’s U.S. insurance subsidiaries may pay dividends, without prior regulatory approval, subject to restrictions set out in state law of the subsidiary’s domicile (or, if applicable, “commercial domicile”). ACE INA’s international subsidiaries are also subject to insurance laws and regulations particular to the countries in which the subsidiaries operate. These laws and regulations sometimes include restrictions that limit the amount of dividends payable without prior approval of regulatory insurance authorities.
ACE Limited did not receive any dividends from ACE Global Markets or ACE INA during the nine months ended September 30, 2007 or 2006. The debt issued by ACE INA to provide partial financing for the ACE INA acquisition and for other operating needs is serviced by statutorily permissible distributions by ACE INA’s insurance subsidiaries to ACE INA as well as other group resources.

Sources of liquidity include cash from operations, routine sales of investments, and financing arrangements. The following is a discussion of our cash flows for the nine months ended September 30, 2007 and 2006.
 
 	•	 	Our consolidated net cash flows from operating activities were $3.9 billion in the nine months ended September 30, 2007, compared with $3.3 billion for the prior year period. These amounts reflect net income for each period, adjusted for non-cash items and changes in working capital. Net income for the nine months ended September 30, 2007, was $2.0 billion, compared with $1.6 billion in the prior year period. For the nine months ended September 30, 2007, significant adjustments included increases in unpaid losses and loss expenses of $958 million and a decrease in reinsurance recoverable and insurance and reinsurance balances receivable of $777 million (primarily due to strong collection of recoveries from prior year catastrophe losses).	
 
 	•	 	Our consolidated net cash flows used for investing activities were $3.7 billion in the nine months ended September 30, 2007, compared with $3.1 billion for the prior year period. For the indicated periods, net investing activities were related principally to net purchases and maturities on the fixed maturities portfolio.	
 
 	•	 	Our consolidated net cash flows used for financing activities were $223 million in the nine months ended September 30, 2007, compared with $207 million in the prior year period. Net cash flows used for financing activities in the nine months ended September 30, 2007, were primarily related to the payment of dividends on Ordinary Shares. During the nine months ended September 30, 2007, we issued $500 million of long-term debt and also repaid $500 million of matured debt. During the prior year period we issued $300 million of long-term debt and also repaid $300 million of matured debt.	
Capital Resources
Capital resources consist of funds deployed or available to be deployed to support our business operations. The following table summarizes the components of our capital resources at September 30, 2007, and December 31, 2006.

Long-term debt includes $500 million of 5.7 percent senior notes due 2017, issued during the first quarter of 2007. The net proceeds of this issuance, together with available cash, were used to repay $500 million of indebtedness which matured in April 2007 and bore interest at 6.0 percent per year.
Total shareholders’ equity increased $1.7 billion in the nine months ended September 30, 2007, primarily due to net income of $2.0 billion, partially offset by dividends declared of $293 million.
On January 12, 2007, and April 13, 2007, we paid dividends of 25 cents per Ordinary Share to shareholders of record on December 29, 2006, and March 30, 2007, respectively. On July 13, 2007, and October 12, 2007, we

paid dividends of 27 cents per share to shareholders of record on June 29, 2007, and September 30, 2007, respectively. We have paid dividends each quarter since we became a public company in 1993. However, the declaration, payment, and value of future dividends on Ordinary Shares is at the discretion of our Board of Directors and will be dependent upon our profits, financial requirements, and other factors including legal restrictions on the payment of dividends and such other factors as our Board of Directors deems relevant. Dividends on the Preferred Shares are payable quarterly when, and if, declared by our Board of Directors in arrears on March 1, June 1, September 1, and December 1 of each year. On March 1, 2007, June 1, 2007, and September 1, 2007, we paid a dividend of $4.875 per Preferred Share to shareholders of record on February 28, 2007, May 31, 2007, and August 31, 2007, respectively.
As part of our capital management program, in November 2001, our Board of Directors authorized the repurchase of any ACE issued debt or capital securities including Ordinary Shares up to $250 million. At September 30, 2007, this authorization had not been utilized. We generally maintain shelf capacity at all times in order to allow capital market access for refinancing as well as for unforeseen capital needs. Consistent with this policy, in 2005, we filed an unlimited shelf registration which expires in December 2008.

 Item 3. Quantitative and Qualitative Disclosures about Market Risk
Refer to the Item 7A included in our Annual Report on Form 10-K for the year ended December 31, 2006. There have been no material changes to this item since December 31, 2006.
 Item 4. Controls and Procedures
As of the end of the period covered by this report, the Company’s management, with the participation of the Company’s Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the design and operation of the Company’s disclosure controls and procedures as defined in Rule 13a-15 under the Securities Exchange Act of 1934. Based upon that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures are effective in allowing information required to be disclosed in reports filed under the Securities and Exchange Act of 1934 to be recorded, processed, summarized, and reported within time periods specified in the rules and forms of the SEC and accumulated and communicated to the Company’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.
During the quarter ended September 30, 2007, there was no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

Our insurance subsidiaries are subject to claims litigation involving disputed interpretations of policy coverages and, in some jurisdictions, direct actions by allegedly-injured persons seeking damages from policyholders. These lawsuits, involving claims on policies issued by our subsidiaries which are typical to the insurance industry in general and in the normal course of business, are considered in our loss and loss expense reserves. In addition to claims litigation, we and our subsidiaries are subject to lawsuits and regulatory actions in the normal course of business that do not arise from, or directly relate to, claims on insurance policies. This category of business litigation typically involves, amongst other things, allegations of underwriting errors or misconduct, employment claims, regulatory activity, or disputes arising from our business ventures.
While the outcomes of the business litigation involving us cannot be predicted with certainty at this point, we are disputing and will continue to dispute allegations against us that are without merit and believe that the ultimate outcomes of the matters in this category of business litigation will not have a material adverse effect on our financial condition, future operating results, or liquidity, although an adverse resolution of a number of these items could have a material adverse effect on our results of operations in a particular quarter or fiscal year.
Information on the insurance industry investigations and related matters is set forth in Note 8 b) to our Consolidated Financial Statements for the quarter ended September 30, 2007.
 Item 1A. Risk Factors
Refer to Item 1A included in our Annual Report on Form 10-K for the year ended December 31, 2006, as updated by Item 1A of Part II included in our Quarterly Reports for the quarters ended June 30, 2007, and March 31, 2007. There have been no material changes to this item since December 31, 2006, other than as disclosed in our Quarterly Reports on Form 10-Q for the quarters ended June 30, 2007, and March 31, 2007.

Exhibit 10.2
Outside Director Awards
Restricted Stock Unit Award Terms
under the
ACE Limited 2004 Long-Term Incentive Plan
The Participant has been granted a Restricted Stock Unit Award by ACE Limited (the “Company”) under the ACE Limited 2004 Long-Term Incentive Plan (the “Plan”). The Restricted Stock Unit Award shall be subject to the following Restricted Stock Unit Award Terms:
1. Terms of Award . Subject to the following Restricted Stock Unit Award Terms, the Participant has been granted the right to receive shares of Stock of the Company (“Units”) as of the Delivery Date. Each “Unit” represents the right to receive one share of Stock. The number of Units awarded to the Participant on the Grant Date is the number reflected in the corporate records and shown in the Record-Keeping System in the Participant’s individual account records. The following words and phrases used in these Restricted Stock Unit Award Terms shall have the meanings set forth in this paragraph 1:
(a) The “Participant” is the individual recipient of the Restricted Stock Unit Award on the Grant Date.
(b) The “Grant Date” is [Insert the date] .
(c) The “Delivery Date” is the six month anniversary date of the Director’s termination from the Board, or such later
date(s) as the Director may elect pursuant to administrative procedures established under the Plan.
(d) Other words and phrases used in these Restricted Stock Unit Award Terms are defined in paragraph 9 or elsewhere in these Restricted Stock Unit Award Terms.
2. Restricted Period . Subject to the limitations of these Restricted Stock Unit Award Terms, the "Restricted Period" for the Units shall begin on the date of the annual shareholders’ meeting held in [year] and end on the date of the annual shareholders’ meeting held in the immediately following year.
Notwithstanding the foregoing, the Restricted Period shall end earlier to the extent set forth below:
(a) The Restricted Period shall end upon the Date of Termination, if the Date of Termination occurs by reason of the Participant’s death.
(b) The Restricted Period shall end upon the Date of Termination, if the Date of Termination occurs by reason of the Participant’s Long-Term Disability.
(c) The Restricted Period shall end upon a Change in Control, provided that such Change in Control occurs on or before the Date of Termination.
3. Forfeiture or Delivery of Shares . Except as otherwise determined by the Committee in its sole discretion, if the Date of Termination occurs prior to the last day of the

Restricted Period, the Participant shall forfeit the Units as of the Date of Termination. If the Date of Termination has not occurred prior to the last day of the Restricted Period, the Units shall be delivered to the Participant on the Delivery Date in the form of Stock free of all restrictions. For the avoidance of doubt, if the Date of Termination is the last day of the Restricted Period, the Units shall be delivered in accordance with the immediately preceding sentence.
4. Withholding . All deliveries and distributions under these Restricted Stock Unit Award Terms are subject to withholding of all applicable taxes. At the election of the Participant, and subject to such rules and limitations as may be established by the Committee from time to time, such withholding obligations may be satisfied through the surrender of shares of Stock which the Participant already owns, or to which the Participant is otherwise entitled under the Plan.
5. Transferability . Except as otherwise provided by the Committee, the Units may not be sold, assigned, transferred, pledged or otherwise encumbered .
6. Dividends . The Participant shall receive additional Units (and not cash) equal to the dividends and distributions paid on shares of Stock to the same extent as if each Unit was a Share of Stock, and those shares were not subject to the restrictions imposed by this Agreement and the Plan; provided, however, that no dividends or distributions shall be payable to or for the benefit of the Participant with respect to record dates for such dividends or distributions occurring on or after the date, if any, on which the Participant has forfeited the Units.
7. Voting . The Participant shall not be a shareholder of record with respect to the Units and shall have no voting rights with respect to the Units during the Restricted Period.
8. Participant’s Rights to Shares . Prior to the delivery of shares of Stock which are to be delivered pursuant to this Agreement, (a) the Participant shall not be treated as owner of the shares, shall not have any rights as a shareholder as to those shares, and shall have only a contractual right to receive them, unsecured by any assets of the Company or its subsidiaries; and (b) the Participant’s right to receive such shares will be subject to the adjustment provisions relating to mergers, reorganizations, and similar events set forth in the Plan.
9. Definitions . For purposes of these Restricted Stock Unit Award Terms, words and phrases shall be defined as follows:
(a) Change in Control . The term “Change in Control” shall be defined as set forth in the Plan.
(b) Date of Termination . The “Date of Termination” means the date the Director resigns or otherwise ceases to perform services as a Director for the Company or a Related Company for any reason.
(c) Director . The term “Director” means a member of the Board who is not an employee of the Company or a Related Company.
 
2

(d) Long-Term Disability . A Participant shall be considered to have a “Long-Term Disability” if the Committee determines, using standards comparable to those used in any long-term disability plan of the Company, that the Participant would be eligible for long-term disability benefits if he or she participated in such plan.
(e) Record-Keeping System . The term “Record-Keeping System” means the record-keeping system developed and maintained by third parties contracted by the Company to keep records and facilitate Participant interfaces with respect to the Plan and awards granted thereunder.
10. Plan Definitions . Except where the context clearly implies or indicates the contrary, a word, term, or phrase used in the Plan is similarly used in these Restricted Stock Unit Award Terms.
11. Heirs and Successors . These Restricted Stock Unit Award Terms shall be binding upon, and inure to the benefit of, the Company and its successors and assigns, and upon any person acquiring, whether by merger, consolidation, purchase of assets or otherwise, all or substantially all of the Company's assets and business. If any benefits deliverable to the Participant under these Restricted Stock Unit Award Terms have not been delivered at the time of the Participant's death, such benefits shall be delivered to the Designated Beneficiary, in accordance with the provisions of these Restricted Stock Unit Award Terms and the Plan. The “Designated Beneficiary” shall be the beneficiary or beneficiaries designated by the Participant in a writing filed with the Committee in such form and at such time as the Committee shall require. If a deceased Participant fails to designate a beneficiary, or if the Designated Beneficiary does not survive the Participant, any rights that would have been exercisable by the Participant and any benefits distributable to the Participant shall be distributed to the legal representative of the estate of the Participant. If a deceased Participant designates a beneficiary and the Designated Beneficiary survives the Participant but dies before the complete distribution of benefits to the Designated Beneficiary under these Restricted Stock Unit Award Terms, then any benefits distributable to the Designated Beneficiary shall be distributed to the legal representative of the estate of the Designated Beneficiary.
12. Administration . The authority to manage and control the operation and administration of these Restricted Stock Unit Award Terms shall be vested in the Committee, and the Committee shall have all powers with respect to these Restricted Stock Unit Award Terms as it has with respect to the Plan. Any interpretation of these Restricted Stock Unit Award Terms by the Committee and any decision made by it with respect to these Restricted Stock Unit Award Terms are final and binding on all persons.
13. Plan and Corporate Records Govern . Notwithstanding anything in these Restricted Stock Unit Award Terms to the contrary, these Restricted Stock Unit Award Terms shall be subject to the terms of the Plan, a copy of which may be obtained by the Participant from the office of the Secretary of the Company; and these Restricted Stock Unit Award Terms are subject to all interpretations, amendments, rules and regulations promulgated by the Committee from time to time pursuant to the Plan. Notwithstanding anything in the Restricted Stock Unit Terms to the contrary, in the event of any discrepancies between the corporate records regarding this award and the Record-Keeping System, the corporate records shall control.
 
3

14. Not An Employment Contract . The Restricted Stock Unit Award will not confer on the Participant any right with respect to continuance of employment or other service with the Company or any Related Company, nor will it interfere in any way with any right the Company or any Related Company would otherwise have to terminate or modify the terms of such Participant's employment or other service at any time.
15. Notices . Any written notices provided for in these Restricted Stock Unit Award Terms or the Plan shall be in writing and shall be deemed sufficiently given if either hand delivered or if sent by fax or overnight courier, or by postage paid first class mail. Notices sent by mail shall be deemed received three business days after mailing but in no event later than the date of actual receipt. Notices shall be directed, if to the Participant, at the Participant's address indicated by the Company's records, or if to the Company, at the Company's principal executive office.
16. Fractional Shares . In lieu of issuing a fraction of a share, resulting from an adjustment of the Restricted Stock Unit Award pursuant to paragraph 5.2(f) of the Plan or otherwise, the Company will be entitled to pay to the Participant an amount equal to the fair market value of such fractional share.
17. Amendment . The Restricted Stock Unit Award Terms may be amended in accordance with the provisions of the Plan, and may otherwise be amended by written agreement of the Participant and the Company without the consent of any other person.
IN WITNESS WHEREOF, the Company has caused these presents to be executed in its name and on its behalf, all as of the Grant Date.
