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 market 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 June 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 restricted stock awards 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, 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 (AEGL) 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.

6. Investments
a) Gross unrealized loss
As of June 30, 2007, there were 9,708 fixed maturities out of a total of 14,259 fixed maturities in an unrealized loss position. The largest single unrealized loss in the fixed maturities was $4.1 million. There were 316 equity securities out of a total of 1,184 equity securities in an unrealized loss position. The largest single unrealized loss

in the equity securities was $1.3 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 June 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 six months ended June 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 $311 million included in Other investments. In connection with these investments, the Company has commitments that may require funding of up to $499 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 26, 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.
(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

Table of Contents
ACE LIMITED AND SUBSIDIARIES
NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
(Unaudited)
 
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. Briefing on these motions concluded on July 31, 2007. All proceedings in the consolidated actions are stayed pending a ruling on defendants’ motion to dismiss.
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. As addressed in the preceding paragraph, all proceedings in this case are stayed pending a ruling on defendants’ motion to dismiss.
ACE, ACE INA Holdings, Inc., ACE USA, Inc., and ACE American Ins. Co., along with a number of other insurers and brokers, have recently 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 two paragraphs, all proceedings in this action are stayed.
ACE USA, Inc., along with a number of other insurers and Marsh, has recently 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. The parties have consented to a consolidation of this case with the consolidated federal actions identified above.

Lloyd’s of London Syndicate 2488 AGM, along with a number of other Lloyd’s of London Syndicates and various brokers, has recently been named as a defendant in 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). The allegations in this putative class-action lawsuit are similar to the allegations in the consolidated federal actions identified above, although this lawsuit focuses on alleged conduct within the London insurance market. This case likely will be transferred to the District of New Jersey for consolidation with the consolidated federal actions identified above.
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. Defendants filed a motion to dismiss the complaint, and the parties are currently awaiting a ruling. Discovery has commenced.
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 Limited, 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 Limited, have been named in one or both of two

(Unaudited)
 
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. The briefing on those motions will proceed according to a briefing schedule agreed upon by the parties. The New York action is stayed until September 14, 2007.
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 of 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 Internal Revenue Service is currently examining the Company’s federal

tax returns for 2002, 2003, and 2004 and the Company anticipates that this examination will be completed by the quarter ended September 30, 2007. The Company anticipates that several proposed adjustments will be disputed at the Appeals Division of the Internal Revenue Service. 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 such examination, 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 six months ended June 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, 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:

Table of Contents

 	•	 	the capital markets;	
 
 	•	 	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).

Net premiums written, which reflect the premiums we retain after purchasing reinsurance protection, were stable in the three and six months ended June 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; refer to Insurance – Overseas General for more information. Our net premiums written reflect growth in our worldwide retail business in the U.S. and internationally, partially offset by decreases in our wholesale and excess and surplus business. We continue to experience a favorable underwriting environment for accident and health business (A&H) internationally, and growth in energy and specialty casualty lines in the U.S. We experienced declines in the U.S. wholesale casualty 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. In general, market conditions globally are becoming increasingly competitive and, as a result, rate decreases have accelerated during the quarter ended June 30, 2007. We note that there is a continuing disparity between renewal pricing and new business pricing, with the latter being more competitive. The stability of our net premiums written reflects our breadth of products, geography, and distribution, which allows us to take advantage of growth opportunities worldwide while maintaining underwriting discipline.

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 three percent and six percent in the three and six months ended June 30, 2007, respectively, compared with the prior year periods. This increase was primarily due to a large assumed loss portfolio contract (written during the first quarter of 2007), increased A&H business, growth in energy and crop/hail lines, and the favorable foreign exchange impact. Net premiums earned in our life operations continued to grow during the first half of 2007, benefiting from increased variable annuity reinsurance and life insurance.
Net investment income increased 21 percent in the three and six months ended June 30, 2007, compared with the prior year periods. The increase in net investment income was primarily due to positive operating cash flows.
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 the periods indicated.

We experienced net catastrophe losses of $81 million and $115 million in the three and six months ended June 30, 2007, respectively. This compares with net catastrophe losses of $2 million and $5 million in the three and six months ended June 30, 2006, respectively. The catastrophe losses incurred during the quarter ended June 30, 2007, were primarily related to floods in the U.K. and Australia and to a lesser extent in the U.S. For the six months ended June 30, 2007, net catastrophe losses 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 $40 million and $58 million in the three and six months ended June 30, 2007, respectively. This compares with net favorable prior period development of $14 million and $46 million in the three and six months ended June 30, 2006. The favorable prior period development in the quarter ended June 30, 2007, was the net result of several underlying favorable and adverse movements. Refer to “Prior Period Development” for more information. The remaining decrease in the loss and loss expense ratio was due to favorable current accident year experience, principally in our property business.
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 decreased primarily due to 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 six months ended June 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 June 30, 2007, compared with the prior year quarter, due primarily to the decrease in outstanding debt.
Our effective tax rate on net income, which we calculate as income tax expense divided by income before income tax, was 20 percent and 18 percent in the three and six months ended June 30, 2007, respectively. This compares with an effective tax rate on net income of 19 percent and 20 percent in the three and six months ended June 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.
Prior Period Development
The favorable prior period development of $40 million in the quarter ended June 30, 2007, was the net result of several underlying favorable and adverse movements. Amongst these movements was net adverse development of $29 million ($19 million after-tax) on catastrophe losses mainly arising from 2005 hurricanes. This was primarily due to a small number of losses on excess policies that reached settlement in the quarter for amounts in excess of our case reserves prompting an adjustment to our projection of ultimate losses during the quarter ended June 30, 2007. These hurricanes present 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. In the sections following the table below, significant prior period movements within each reporting segment are discussed in more detail.

**	We reclassified $46 million from short-tail to specialty for Insurance – North American in the three months ended March 31, 2006.	
Insurance – North American
Insurance – North American experienced $6 million of net favorable prior period development and $4 million of net adverse prior period development in the three and six months ended June 30, 2007, respectively, compared with net adverse prior period development of $11 million and $15 million in the three and six months ended June 30, 2006, respectively. The net prior period development for the quarter ended June 30, 2007, was the net result of several underlying adverse and favorable movements. The largest adverse movements follow:
 
 	•	 	Short-tail development on the 2005 accident year hurricanes in the amount of $29 million (noted above).	
 
 	•	 	Two long-tail workers’ compensation portfolios in the amount of $18 million:	
 
 	•	 	The first portfolio, a runoff book of first dollar workers’ compensation written through a managing general agent, impacted the 2000-2003 accident years. During the latter half of 2006 and into the first half of 2007, all open claim files were reviewed on this portfolio and adjustments to case reserves were recorded. This claims activity was greater than our expectations leading to a $6 million increase in our estimates of ultimate claims.	
 
 	•	 	The second portfolio was our high deductible workers’ compensation business where we experienced adverse development of $12 million for the 2005 and prior accident years. This adverse development was due to unfavorable trends in allocated claims expense, primarily in the 2002 – 2004 accident years. Allocated claims expense includes costs directly attributable to claims such as claim service and legal costs. Since this portfolio is in excess of deductibles, as the accident years mature, we have been assigning greater credibility towards experience-based methods and away from the expected loss ratio method. The loss development approaches, while highly leveraged, indicate higher allocated claims cost than our initial expectations.

Table of Contents

 	•	 	Based on an appeals court ruling rendered during the quarter ended June 30, 2007, our liabilities for future costs for two related specialty claims from a runoff financial guaranty program were re-evaluated and increased by $20 million.	
The most significant items of favorable prior period development follow:
 
 	•	 	Favorable development of $52 million arising from ACE USA’s national accounts workers’ compensation business, primarily for the 2006 accident year. Reported losses for large claims including multi-claimant industrial accidents on our high deductible and excess business have been better than expected to date and in the quarter ended June 30, 2007.	
 
 	•	 	Favorable development on national accounts long-tail casualty lines of $21 million for the 2002-2004 accident years. This business is generally written excess of a self insured retention or deductible and therefore, losses tend to be slow to emerge and develop. Loss activity over the last 12 months has been favorable relative to expectations and as the loss history matures and gains credibility, we have assigned greater weight towards experience-based methods than expected loss ratio method.	
 
 	•	 	Settlements of $5 million relating to the 2006 crop year in our crop/hail specialty product line. This prior period crop/hail movement was the direct result of the loss amounts in current loss reports issued during the second quarter of 2007 being lower than our preliminary estimate.	
The net prior period development for the quarter ended June 30, 2006, was the net result of several underlying favorable and adverse movements, the most significant of which follow:
 
 	•	 	Favorable development of $12 million on lines with short-tail and specialty exposures (property, workers’ compensation CAT and crop/hail) identified as part of our standard quarterly reserving process. This movement was primarily due to the following:	
 
 	•	 	Increases in the estimate of ultimate losses on catastrophes from the 2005 accident year of $60 million.	
 
 	•	 	Favorable development of $51 million on ACE USA’s workers’ compensation short-tail catastrophe and industrial accident exposure primarily arising from accident years 2004 and 2005, following the review of reported loss experience relative to expectations.	
 
 	•	 	Favorable development on specialty crop/hail business of $14 million due to recording of the final settlement of the 2005 crop year results. This was previously classified as short-tail business.	
 
 	•	 	Adverse development of $21 million on long-tail business driven by the following major changes:	
 
 	•	 	Adverse development of $10 million due to higher than anticipated loss emergence on two run-off programs of workers’ compensation written by ACE Westchester Specialty prior to 2003.	
 
 	•	 	Adverse development of $11 million on the Bermuda directors and officers liability book due primarily to a case estimate increase on a single claim from the 2002 accident year.	
Insurance – Overseas General
Insurance – Overseas General experienced $31 million and $52 million of net favorable prior period development in the three and six months ended June 30, 2007, respectively, compared with net favorable prior period development of $21 million and $60 million in the three and six months ended June 30, 2006, respectively. The net prior period development for the quarter ended June 30, 2007, was the net result of several underlying favorable and adverse movements, the most significant of which follow:
 
 	•	 	Favorable prior period development of $21 million on short-tail property and fire lines primarily in accident year 2006 in Europe. The length of the payment and reporting patterns for the short-tail property and fire lines is such that a reasonable determination of the prior accident year can be made

 	after six months. The favorable development in the quarter arose on the 2006 accident year and was driven by lower than anticipated frequency and severity of late reported property claims that emerged during the quarter and favorable development and settlement of several previously reported large losses.	
 
 	•	 	Favorable prior period development of $10 million in marine, primarily in accident years 1999-2002 in ACE Global Markets. This favorable prior period development was largely driven by the settlement and resulting commutation in the quarter ended June 30, 2007, of several legacy underwriting agreements on terms better than those used to establish the held reserves.	
 
 	•	 	Favorable prior period development of $6 million in A&H primarily in accident years 2005 and 2006 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 and group A&H businesses across several countries with no particular underlying trend identifiable.	
 
 	•	 	Adverse prior period development of $5 million in ACE Global Markets aviation driven primarily by case reserve deterioration in the quarter on a single large event in accident year 2006.	
The last three items are all included in specialty lines.
The net prior period development for the quarter ended June 30, 2006 was the net result of several underlying favorable and adverse movements, the most significant of which follow:
 
 	•	 	Favorable prior period development of $30 million on property lines primarily from the 2005 accident year. Of this amount $16 million was related to ACE International business and can be attributed to better than expected loss emergence. The remainder is in respect of ACE Global Markets business and was largely due to case estimate reductions on 2005 catastrophe claims.	
 
 	•	 	Adverse prior period development of $9 million on aviation and A&H. These movements were the result of reserve strengthening for specific programs.	
Global Reinsurance
Global Reinsurance experienced $3 million and $10 million of net favorable prior period development in the three and six months ended June 30, 2007, respectively, compared with net favorable prior period development of $4 million and $1 million in the three and six months ended June 30, 2006, respectively. The net prior period development for the quarter ended June 30, 2007, was the net result of several underlying favorable and adverse movements:
 
 	•	 	The largest favorable movement was related to short-tail and specialty lines of $9 million in years 2006 and prior as a result of claims closing or better than expected claims development in recent quarters.	
 
 	•	 	The largest adverse prior period movements follow:	
 
 	•	 	Adverse movement of $3 million for long-tail business in the 2002 year due to worse than expected claims development over the last few quarters.	
 
 	•	 	Adverse movement of $3 million from short-tail and specialty business in years 2003 and 2006 due to specific large claims.	
The net prior period development for the quarter ended June 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 $2 million across a wide range of business areas, mostly relating to short-tail exposures.
Segment Operating Results – Three and Six Months Ended June 30, 2007 and 2006
The discussions that follow include tables which show segment operating results for the three and six months ended June 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.
Insurance – North American
The Insurance – North American segment comprises our P&C operations 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.

Net premiums written for the Insurance – North American segment were stable in the three and six months ended June 30, 2007, compared with the prior year periods. ACE USA, the U.S.-based retail division, was the only operation in this segment to report growth in overall net premiums written in the first half of 2007. ACE USA’s growth for the quarter ended June 30, 2007, was primarily driven by increased production in the large account risk management unit and specialty casualty (professional risk, custom casualty, environmental , and construction) and energy lines. For the six months ended June 30, 2007, the increase in ACE USA’s net premiums written was primarily driven by 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 Specialty, the wholesale operation, reported decreases in net premiums written, primarily due to competitive conditions for new and renewal business in casualty lines, particularly construction industry related accounts. The declines in casualty lines were

partially offset by increased crop/hail production as a result of higher commodity prices. ACE Bermuda reported decreases in net premiums written primarily due to a decline in assumed loss portfolio business and, to a lesser extent, excess liability and professional lines. 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.
The following two tables provide a line of business and entity/divisional breakdown of Insurance – North American’s net premiums earned for the periods indicated.

ACE USA’s net premiums earned increased 11 percent and 19 percent in the three and six months ended June 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 higher production and net retention ratio in the large account risk management unit, 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 Specialty’s net premiums earned increased three percent in the quarter ended June 30, 2007, and decreased one percent in the six months ended June 30, 2007, compared with the prior year periods. Production in casualty lines has declined in the first half of 2007, compared with the prior year period, offset by growth in crop/hail business during the quarter ended June 30, 2007. ACE Bermuda’s net premiums earned decreased 19 percent and 18 percent in the three and six months ended June 30, 2006, respectively, compared with the prior year periods, primarily due to a decrease in assumed loss portfolio business.
Insurance – North American’s reported loss and loss expense ratio was stable in the three and six months ended June 30, 2007, compared with the prior year periods.

ended June 30, 2007, were primarily related to floods in the U.S. Insurance – North American incurred net favorable prior period development of $6 million in the three months ended June 30, 2007, and net unfavorable prior period development of $4 million in the six months ended June 30, 2007. This compares with net unfavorable prior period development of $11 million and $15 million in the three and six months ended June 30, 2006, respectively. Refer to “Prior Period Development” for more detail. During the quarter ended June 30, 2007, we had a $16 million release for a bad debt provision, principally for a specific reinsurance recoverable we now expect to collect. The loss and loss expense ratio for the six months ended June 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 decreased in the three and six months ended June 30, 2007, compared with the prior year periods. This decrease was primarily related to the reductions in policy acquisition costs at ACE USA and ACE Westchester Specialty during the first quarter of 2007. The decline in the policy acquisition cost ratio at ACE USA 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 Specialty, the decline in the policy acquisition cost ratio was due to lower profit share commissions on crop business.
Administrative expenses increased in the three and six months ended June 30, 2007, compared with the prior year periods. The increases were 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, for ACE USA, the quarter ended June 30, 2006, was favorably impacted by recoveries relating to amounts previously written off. The administrative expense ratio decreased due to the impact of the increase in net premiums earned outpacing the increased administrative expenses, primarily reflecting the large assumed loss portfolio contract.

Insurance – Overseas General’s net premiums written increased eight percent and six percent in the three and six months ended June 30, 2007, respectively, compared with the prior year periods. Foreign exchange accounted for most of this growth as both the euro and the pound sterling strengthened significantly relative to the U.S. dollar in the first half 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 in the U.K. and Asia Pacific due to competitive conditions for new accounts and adverse pricing on renewal business. ACE International’s P&C business has been experiencing modest growth in continental Europe and Latin America during the first half of 2007. ACE Global Markets reported increased reinsurance costs combined with rate decreases due to competition for aviation, property, and financial lines, partially offset by increased production in energy and A&H lines.
The following two tables provide a line of business and entity/divisional breakdown of Insurance – Overseas General’s net premiums earned for the periods indicated.

Insurance – Overseas General’s net premiums earned increased five percent and six percent in the three and six months ended June 30, 2007, respectively, compared with the prior year periods, primarily due to the impact of foreign exchange. Over the past several quarters, this segment has experienced growth in A&H business, offset by weak market conditions for U.K. P&C business and higher reinsurance costs for certain lines.
ACE International’s net premiums earned increased seven percent and nine percent in the three and six months ended June 30, 2007, respectively, compared with the prior year periods, primarily due to the impact of foreign exchange. Generally, in the U.K., competition for P&C business has put pressure on rates, terms, and conditions, while A&H business in Europe 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 Latin America has also been experiencing growth in its P&C business. ACE Global Markets’ net premiums earned decreased two percent and three percent in the three and six months ended June 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 conducts business internationally and in most major foreign currencies. The following table summarizes the approximate effect of changes in foreign currency exchange rates on the growth of net premiums written and earned for the periods indicated.

Insurance – Overseas General recorded net catastrophe losses of $58 million and $73 million in the three and six months ended June 30, 2007, respectively, compared with $nil in the prior year periods. The catastrophe losses incurred during the quarter ended June 30, 2007, were primarily related to floods in the U.K. and Australia. For the six months ended June 30, 2007, net catastrophe losses also include the impact of European windstorm Kyrill. Insurance – Overseas General experienced net favorable prior period development of $31 million and $52 million in the three and six months ended June 30, 2007, respectively, compared with net favorable prior period development of $21 million and $60 million, respectively, in the prior year periods. Refer to “Prior Period Development” for more detail. The remaining decreases to the loss and loss expense ratio were a result of favorable current accident year experience at ACE International and ACE Global Markets.
Insurance – Overseas General’s policy acquisition cost ratio was impacted by 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 six months ended June 30, 2007, compared with the prior year periods. This increase was primarily due to costs associated with ACE International’s entrance into emerging markets, specifically Eastern Europe and the Middle East, and spending in support of growth at Asia Pacific.

Global Reinsurance’s net premiums written decreased 20 percent in the three and six months ended June 30, 2007, compared with the prior year periods. For the three and six months ended June 30, 2007, Global Reinsurance reported decreased net premiums written due to declines in production as clients generally opted to increase risk retention, which resulted in increased competition and lower prices. This decrease was partially offset by favorable rates during the June renewal period for ACE Tempest Re Bermuda.

Global Reinsurance’s net premiums earned decreased 16 percent and 12 percent in the three and six months ended June 30, 2007, respectively, compared with the prior year periods. ACE Tempest Re Bermuda reported stable net premiums earned as the decline in production in the first half of 2007 was offset by earnings on property catastrophe premiums written in 2006. ACE Tempest Re USA’s decrease was a result of a decrease in quota-share net premiums written in 2006 and the first half of 2007. ACE Tempest Re Europe reported a decline in net premiums earned, primarily due to reduced production in 2006 and the first half of 2007. ACE Tempest Re Canada commenced writing business in 2007.

Global Reinsurance reported $7 million and $26 million of net catastrophe losses in the three and six months ended June 30, 2007, respectively. This compares with net catastrophe losses of $2 million and $5 million in the three and six months ended June 30, 2006, respectively. The catastrophe losses incurred during the quarter ended June 30, 2007, were primarily related to floods in the U.K. and Australia. For the six months ended June 30, 2007, net catastrophe losses were primarily related to European windstorm Kyrill. Global Reinsurance incurred net favorable prior period development of $3 million and $10 million in the three and six months ended June 30, 2007, respectively. This compares with net favorable prior period development of $4 million and $1 million in the three and six months ended June 30, 2006, respectively. Refer to “Prior Period Development” for more detail. The remaining decrease in the loss and loss expense ratio was primarily due to changes in the mix of business.
The policy acquisition cost ratio decreased in the three and six months ended June 30, 2007, primarily due to changes in our mix of business as well as lower ceding commissions. The administrative expense ratio increased during the three and six months ended June 30, 2007, due to the decrease in net premiums earned.

Life underwriting income increased in the three and six months ended June 30, 2007, compared with the prior year periods, due to increased net premiums earned combined with a reduction in the benefit ratio at ACE Life Re. The increase in net premiums earned was primarily due to growth in ACE Life’s Thailand operations as well as the U.S. based traditional life reinsurance business, which was launched in 2006. ACE Life Re’s life and annuity benefits decreased as a percentage of net premiums earned primarily due to more favorable economic conditions in the three and six months ended June 30, 2007, compared with the prior year periods. 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.
Life Insurance and Reinsurance’s administrative expenses increased primarily due to increased expenses at ACE Life to support business development opportunities. Net realized gains (losses) consist of market value movement of the investment portfolio and fair value movement of guaranteed minimum income benefits (GMIBs), which occur due to changes in the level and  volatility of interest rates and equity markets.

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 21 percent in the three and six months ended June 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. The investment portfolio’s average market yield on fixed maturities was 5.7 percent at June 30, 2007 and 2006.

Net Realized Gains (Losses)
Our investment strategy takes a long-term view and our investment portfolio is actively managed 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 includes a table which summarizes all of our securities in an unrealized loss position at June 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 six months ended June 30, 2007, included losses of $16 million and $54 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 six months ended June 30, 2006, these losses amounted to $61 million and $92 million, respectively. A breakdown of “other-than-temporary” impairments is included in Note 6 b) to the Consolidated Financial Statements.

Other income for the three and six months ended June 30, 2007 and 2006, is primarily comprised of our equity in net income of Assured Guaranty (included in equity in net income of partially-owned companies). 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 3.7 years at June 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 June 30, 2007. Our “other investments” principally comprise direct investments, investment funds, and limited partnerships. Our exposure to sub-prime mortgages is $280 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 with over 400,000 loans, and has a short duration of 2.2 years. We have had no impact to-date from problems in this market nor do we expect any. There has been a widening of spreads on these holdings but there has been very little market value impact.
The following table shows the fair value and cost/amortized cost of our invested assets at June 30, 2007 and December 31, 2006.

Net reinsurance recoverable	  	$	14,081	 	 	$	14,580	 	
	  	 	 	 	 	 	 	 	
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 unpaid losses and loss expenses for the six months ended June 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.

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, the 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 Corporation (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 net balance at December 31, 2006 has been reduced by $50 million of reinsurance recoverable and $25 million of provision for uncollectible reinsurance as these balances were unrelated to A&E exposures.	
The A&E net loss reserves including allocated and unallocated loss expense reserves and provision for uncollectible reinsurance at March 31, 2007, of $2.0 billion shown in the above table are comprised of $1.476 billion in reserves held by Brandywine run-off companies, $219 million of reserves held by Westchester Specialty, $175 million of reserves held by ACE Bermuda, $122 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 speed at which the related claims will be paid. 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 operations of ACE Overseas General and participations by ACE Bermuda as a co-reinsurer or retrocessionaire in the NICO contracts.
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 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 reinsurance agreements between those companies and Century. The Brandywine NICO Agreement was exhausted on an incurred basis in the fourth quarter of 2002.
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 December 31, 2006, 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.
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,
 
48

Table of Contents
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.
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 group 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 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, the ACE INA insurance subsidiaries provided insurance coverage to Century in the amount of $800 million under an aggregate excess of loss reinsurance agreement (the Aggregate Excess of Loss Agreement) if 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 March 31, 2007, was $25 million and approximately $346 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

Table of Contents
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 under GAAP, 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 March 31, 2007, approximately $654 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 $146 million. At December 31, 2006, the remaining limit of coverage under the agreement was also $146 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 report 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 March 31, 2007, the aggregate reinsurance balances ceded by the active ACE companies to Century were approximately $1.5 billion. At March 31, 2007, Century’s carried gross reserves (including reserves ceded by the active ACE companies to Century) were $3.9 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 March 31, 2007, approximately $1.8 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 to Century’s 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 March 31, 2007, reserves ceded by Century to the active ACE companies and other amounts owed to Century by the active ACE companies were approximately $655 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 $1 billion 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 $1 billion (or approximately seven percent of our total shareholders’ equity at June 30, 2007). We estimate that at such loss levels, aggregate industry losses are approximately $125 billion. If the 2005 hurricanes were to recur, our net losses on an “as-if” basis would be 30 percent lower. ACE’s modeled losses reflect our in-force portfolio and catastrophe reinsurance program as of April 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 six months ended June 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 June 30, 2007, our available credit lines totaled $2.8 billion, and usage was $1.7 billion. During the quarter ended June 30, 2007, Syndicate 2488 reduced the letters of credit supporting its Funds at Lloyd’s in line with the requirement promulgated by Lloyd’s. As at June 30, 2007, our Funds at Lloyd’s credit facility was approximately $601 million (£300 million) with usage of approximately $468 million (£234 million).
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 six months ended June 30, 2007 and 2006, ACE Bermuda declared and paid dividends of $168 million and $137 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 six months ended June 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 quarters ended June 30, 2007 and 2006.
 
 	•	 	Our consolidated net cash flows from operating activities were $2.4 billion in the six months ended June 30, 2007, compared with $2 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 six months ended June 30, 2007, was $1.3 billion, compared with $1.1 billion in the prior year period. For the six months ended June 30, 2007, significant adjustments included increases in unpaid losses and loss expenses and unearned premiums of $943 million and a decrease in reinsurance recoverable of $548 million (due to strong collection of recoveries from prior year catastrophe losses). These increases were partially offset by $745 million primarily due to an increase in insurance and reinsurance balances receivable, prepaid reinsurance, and accounts payable.	
 
 	•	 	Our consolidated net cash flows used for investing activities were $2.2 billion in the six months ended June 30, 2007, compared with $2.1 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.

Table of Contents

 	•	 	Our consolidated net cash flows used for financing activities were $139 million in the six months ended June 30, 2007, compared with net cash flows from financing activities of $165 million the prior year period. Net cash flows used for financing activities in the six months ended June 30, 2007, were primarily related to the payment of dividends on Ordinary Shares. During the first half of 2007, we issued $500 million of long-term debt and also repaid $500 million of matured debt. The prior year period was impacted by net proceeds from issuance of $300 million in long-term 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 June 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 $906 million in the six months ended June 30, 2007, primarily due to net income of $1.3 billion, partially offset by unrealized depreciation on our investment portfolio of $331 million, and by dividends declared of $193 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, we paid dividends of 27 cents per share to shareholders of record on June 29, 2007. 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, and June 1, 2007, we paid a dividend of $4.875 per Preferred Share to shareholders of record on February 28, 2007, and May 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 June 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.

PART ii OTHER INFORMATION
Item 1. Legal Proceedings
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.
Item 1A. Risk Factors
The following supplements the factors that could have a material impact on our results of operations or financial condition as described under “Risk Factors” in Item 1A. of Part I of our 2006 Annual Report on Form 10-K and under “Risk Factors” in Item 1A. of Part II of our quarterly report on Form 10-Q for the quarter ended March 31, 2007.
We have substantial exposure to losses resulting from natural disasters, man-made catastrophes and other catastrophic events. Catastrophes can be caused by various events, including hurricanes, typhoons, earthquakes, hailstorms, explosions, severe winter weather, fires, war, acts of terrorism, political instability, and other natural or man-made disasters. The incidence and severity of catastrophes are inherently unpredictable and our losses from catastrophes could be substantial. In addition, changing climate conditions, primarily rising global temperatures, may be increasing, or may in the future increase the frequency and severity of natural catastrophes, including weather events, and may create new types of catastrophe losses. The occurrence of claims from catastrophic events is likely to result in substantial volatility in our results of operations or financial condition for any fiscal quarter or year. Increases in the values and concentrations of insured property may increase the severity of these occurrences in the future. Although we attempt to manage our exposure to such events through the use of underwriting controls and purchase of third-party reinsurance, catastrophic events are inherently unpredictable and the actual nature of such events when they occur could be more frequent or severe than contemplated in our pricing and risk management expectations. As a result, the occurrence of one or more catastrophic events could have a material adverse effect on our results of operations or financial condition.

Exhibit 10.1
FORM OF SECOND AMENDED AND RESTATED
INDEMNIFICATION AGREEMENT
THIS SECOND AMENDED AND RESTATED INDEMNIFICATION AGREEMENT (this “Agreement”) is entered into effective as of May 17, 2007 by and between ACE Limited, a Cayman Islands company (the “Company”), and [                    ] (“Indemnitee”).
WHEREAS, it is essential to the Company to retain and attract as directors and officers the most capable persons available;
WHEREAS, Indemnitee is a director and/or officer of the Company;
WHEREAS, both the Company and Indemnitee recognize the increased risk of litigation and other claims currently being asserted against directors and officers of corporations;
WHEREAS, the Articles of Association of the Company require the Company to indemnify its directors and officers to the fullest extent permitted by law, and permit the Company to advance expenses relating to the defense of indemnification matters, and the Indemnitee has been serving and continues to serve as a director and/or officer of the Company in part in reliance on the Company’s Articles of Association;
WHEREAS, in recognition of Indemnitee’s need for (i) substantial protection against personal liability based on Indemnitee’s reliance on the aforesaid Articles of Association, (ii) specific contractual assurance that the protection promised by the Articles of Association will be available to Indemnitee (regardless of, among other things, any amendment to or revocation of the Articles of Association or any change in the composition of the Company’s Board of Directors or acquisition transaction relating to the Company), and (iii) an inducement to provide effective services to the Company as a director and/or officer, the Company wishes to provide in this Agreement for the indemnification of and the advancing of expenses to Indemnitee to the fullest extent (whether partial or complete) permitted under law and as set forth in this Agreement, and, to the extent insurance is maintained, to provide for the continued coverage of Indemnitee under the Company’s directors’ and officers’ liability insurance policies;
WHEREAS, the Company and Indemnitee have previously entered into an amended and restated indemnification agreement, dated as of November 17, 2005 (the “First Amended Agreement”), and now desires to amend and restate in its entirety the First Amended Agreement as set forth herein.
NOW, THEREFORE, in consideration of the above premises and of Indemnitee continuing to serve the Company directly or, at its request, with another enterprise, and intending to be legally bound hereby, the parties agree as follows:
1. Certain Definitions:
(a) Board : the Board of Directors of the Company.

(b) Affiliate : any corporation or other person or entity that directly, or indirectly through one or more intermediaries, controls or is controlled by, or is under common control with, the person specified.
(c) Change in Control : shall be deemed to have occurred if:
(i) any “person,” as such term is used in Sections 3(a)(9) and 13(d) of the United States Securities Exchange Act of 1934, becomes a “beneficial owner,” as such term is used in Rule 13d-3 promulgated under that act, of 50% or more of the Voting Stock (as defined below) of the Company;
(ii) the majority of the Board consists of individuals other than Incumbent Directors, which term means the members of the Board on the Effective Date; provided that any person becoming a director subsequent to such date whose election or nomination for election was supported by three-quarters of the directors who then comprised the Incumbent Directors shall be considered to be an Incumbent Director;
(iii) the Company adopts any plan of liquidation providing for the distribution of all or substantially all of its assets;
(iv) all or substantially all of the assets or business of the Company is disposed of pursuant to a merger, consolidation or other transaction (unless the shareholders of the Company immediately prior to such merger, consolidation or other transaction beneficially own, directly or indirectly, in substantially the same proportion as they owned the Voting Stock of the Company, all of the Voting Stock or other ownership interests of the entity or entities, if any, that succeed to the business of the Company); or
(v) the Company combines with another company and is the surviving corporation but, immediately after the combination, the shareholders of the Company immediately prior to the combination hold, directly or indirectly, 50% or less of the Voting Stock of the combined company (there being excluded from the number of shares held by such shareholders, but not from the Voting Stock of the combined company, any shares received by Affiliates (as defined below) of such other company in exchange for stock of such other company).
For the purpose of this definition of “Change in Control,” (I) an “Affiliate” of a person or other entity shall mean a person or other entity that directly or indirectly controls, is controlled by, or is under common control with the person or other entity specified and (II) “Voting Stock” shall mean capital stock of any class or classes having general voting power under ordinary circumstances, in the absence of contingencies, to elect the directors of a corporation.
(d) Defense Costs : attorneys’ fees and expenses and costs of investigation paid or incurred in connection with investigating, defending, prosecuting (subject to Section 2(b)), being a witness in, participating in (including on appeal), or preparing for any of the foregoing in, any Proceeding relating to any Type 2 Indemnifiable Event.
 
2

(e) Expenses : any expense, liability, or loss, including attorneys’ fees, judgments, fines, ERISA excise taxes and penalties, amounts paid or to be paid in settlement, any interest, assessments, or other charges imposed thereon, any federal, state, local, or foreign taxes imposed as a result of the actual or deemed receipt of any payments under this Agreement, and all other costs and obligations, paid or incurred in connection with investigating, defending, prosecuting (subject to Section 2(b)), being a witness in, participating in (including on appeal), or preparing for any of the foregoing in, any Proceeding relating to any Type 1 Indemnifiable Event.
(f) Indemnifiable Event : (i) any event or occurrence that takes place either prior to or after the execution of this Agreement, related to the fact that Indemnitee is or was a director or officer of the Company, or while a director or officer is or was serving at the request of the Company as a director, officer, employee, trustee, agent, or fiduciary of another foreign or domestic corporation, partnership, limited liability company, joint venture, employee benefit plan, trust, or other enterprise, or was a director, officer, employee, or agent of a foreign or domestic corporation that was a predecessor corporation of the Company or of another enterprise at the request of such predecessor corporation, or related to anything done or not done by Indemnitee in any such capacity, whether or not the basis of the Proceeding is alleged action in an official capacity as a director, officer, employee, or agent or in any other capacity while serving as a director, officer, employee, or agent of the Company, as described above or (ii) any event or occurrence that takes place either prior to or after the execution of the First Amended Agreement, related to the fact that Indemnitee is or was a director, officer, employee, trustee, agent, or fiduciary of another foreign or domestic corporation, partnership, limited liability company, joint venture, employee benefit plan, trust, or other enterprise and that relates to the subject matter of the investigations referred to in the Company’s Annual Report on Form 10-K for the year ended December 31, 2004 or any other investigation (whether or not the Company is a target of such investigation) by any government entity covering subject matter that is substantially similar to the subject matter of, or arises out of, the foregoing investigations.
(g) Independent Counsel : the person or body appointed in connection with Section 3.
(h) Proceeding : any threatened, pending, or completed action, suit, or proceeding or any alternative dispute resolution mechanism (including an action by or in the right of the Company), or any inquiry, hearing, or investigation, whether conducted by the Company or any other party, that Indemnitee in good faith believes might lead to the institution of any such action, suit, or proceeding, whether civil, criminal, administrative, investigative, or other.
(i) Reviewing Party : the person or body appointed in accordance with Section 3.
(j) Type 1 Indemnifiable Event : an Indemnifiable Event of the type described in clause (i) of the definition of Indemnifiable Event.

(l) Voting Securities : any securities of the Company that vote generally in the election of directors.
2. Agreement to Indemnify .
(a) General Agreement . In the event Indemnitee was, is, or becomes a party to or witness or other participant in, or is threatened to be made a party to or witness or other participant in, a Proceeding by reason of (or arising in part out of) a Type 1 Indemnifiable Event, the Company shall indemnify Indemnitee from and against any and all Expenses to the fullest extent permitted by law, as the same exists or may hereafter be amended or interpreted (but in the case of any such amendment or interpretation, only to the extent that such amendment or interpretation permits the Company to provide broader indemnification rights than were permitted prior thereto). In the event Indemnitee was, is, or becomes a party to or witness or other participant in, or is threatened to be made a party to or witness or other participant in, a Proceeding by reason of (or arising in part out of) a Type 2 Indemnifiable Event, the Company shall indemnify Indemnitee from and against any and all Defense Costs to the fullest extent permitted by law, as the same exists or may hereafter be amended or interpreted (but in the case of any such amendment or interpretation, only to the extent that such amendment or interpretation permits the Company to provide broader indemnification rights than were permitted prior thereto). The parties hereto intend that this Agreement shall provide for indemnification in excess of that expressly permitted by statute, including, without limitation, any indemnification provided by the Company’s Articles of Association, vote of its shareholders or disinterested directors, or applicable law.
(b) Initiation of Proceeding . Notwithstanding anything in this Agreement to the contrary, Indemnitee shall not be entitled to indemnification pursuant to this Agreement in connection with any Proceeding initiated by Indemnitee against the Company or any director or officer of the Company unless (i) the Company has joined in or the Board has consented to the initiation of such Proceeding; (ii) the Proceeding is one to enforce indemnification rights under Section 5; or (iii) the Proceeding is instituted after a Change in Control (other than a Change in Control approved by a majority of the directors on the Board who were directors immediately prior to such Change in Control) and Independent Counsel has approved its initiation.
(c) Expense Advances . If so requested by Indemnitee, the Company shall advance (within ten business days of such request) any and all Expenses (in the case of a Type 1 Indemnifiable Event) or Defense Costs (in the case of a Type 2 Indemnifiable Event) to Indemnitee (in either case, an “Expense Advance”); provided that, (i) such an Expense Advance shall be made only upon delivery to the Company of an undertaking by or on behalf of the Indemnitee to repay the amount thereof if it is ultimately determined that Indemnitee is not entitled to be indemnified by the Company, and (ii) if and to the extent that the Reviewing Party determines that Indemnitee would not be permitted to be so indemnified under applicable law, the Company shall be entitled to be reimbursed by
 
4

Indemnitee (who hereby agrees to reimburse the Company) for all such amounts theretofore paid. If Indemnitee has commenced or commences legal proceedings in a court of competent jurisdiction to secure a determination that Indemnitee should be indemnified under applicable law, as provided in Section 4, any determination made by the Reviewing Party that Indemnitee would not be permitted to be indemnified under applicable law shall not be binding, and Indemnitee shall not be required to reimburse the Company for any Expense Advance until a final judicial determination is made with respect thereto (as to which all rights of appeal therefrom have been exhausted or have lapsed). Indemnitee’s obligation to reimburse the Company for Expense Advances shall be unsecured and no interest shall be charged thereon.
(d) Mandatory Indemnification . Notwithstanding any other provision of this Agreement, to the extent that Indemnitee has been successful on the merits or otherwise in defense of any Proceeding relating in whole or in part to a Type 1 Indemnifiable Event or in defense of any issue or matter therein, Indemnitee shall be indemnified against all Expenses incurred in connection therewith.
(e) Partial Indemnification . If Indemnitee is entitled under any provision of this Agreement to indemnification by the Company for some or a portion of Expenses (in the case of a Type 1 Indemnifiable Event) or Defense Costs (in the case of a Type 2 Indemnifiable Event), but not, however, for the total amount thereof, the Company shall nevertheless indemnify Indemnitee for the portion thereof to which Indemnitee is entitled.
(f) Prohibited Indemnification . No indemnification pursuant to this Agreement shall be paid by the Company:
(i) on account of any Proceeding in which judgment is rendered against Indemnitee for an accounting of profits made from the purchase or sale by Indemnitee of securities of the Company pursuant to the provisions of Section 16(b) of the Securities Exchange Act of 1934, as amended, or similar provisions of any federal, state, or local laws; or
(ii) if a court of competent jurisdiction by a final judicial determination, shall determine that such indemnity is not permitted under applicable law.
3. Reviewing Party . Prior to any Change in Control, the Reviewing Party shall be any appropriate person or body consisting of a member or members of the Board or any other person or body appointed by the Board who is not a party to the particular Proceeding with respect to which Indemnitee is seeking indemnification; after a Change in Control, the Independent Counsel referred to below shall become the Reviewing Party. With respect to all matters arising after a Change in Control (other than a Change in Control approved by a majority of the directors on the Board who were directors immediately prior to such Change in Control) concerning the rights of Indemnitee to indemnity payments and Expense Advances under this Agreement or any other agreement or under applicable law or the Company’s Articles of Association now or hereafter in effect relating to indemnification for Indemnifiable Events, the
 
5

Company shall seek legal advice only from Independent Counsel selected by Indemnitee and approved by the Company (which approval shall not be unreasonably withheld), and who has not otherwise performed services for the Company or the Indemnitee (other than in connection with indemnification matters) within the last five years. The Independent Counsel shall not include any person who, under the applicable standards of professional conduct then prevailing, would have a conflict of interest in representing either the Company or Indemnitee in an action to determine Indemnitee’s rights under this Agreement. Such counsel, among other things, shall render its written opinion to the Company and Indemnitee as to whether and to what extent the Indemnitee should be permitted to be indemnified under applicable law. The Company agrees to pay the reasonable fees of the Independent Counsel and to indemnify fully such counsel against any and all expenses (including attorneys’ fees), claims, liabilities, loss, and damages arising out of or relating to this Agreement or the engagement of Independent Counsel pursuant hereto.
4. Indemnification Process and Appeal .
(a) Indemnification Payment . Indemnitee shall be entitled to indemnification of Expenses (in the case of a Type 1 Indemnifiable Event) or Defense Costs (in the case of a Type 2 Indemnifiable Event), and shall receive payment thereof, from the Company in accordance with this Agreement as soon as practicable after Indemnitee has made written demand on the Company for indemnification, unless the Reviewing Party has given a written opinion to the Company that Indemnitee is not entitled to indemnification under applicable law.
(b) Suit to Enforce Rights . Regardless of any action by the Reviewing Party, if Indemnitee has not received full indemnification within thirty days after making a demand in accordance with Section 4(a), Indemnitee shall have the right to enforce its indemnification rights under this Agreement by commencing litigation in any court in the U.S. District Court for the Southern District of New York having subject matter jurisdiction thereof seeking an initial determination by the court or challenging any determination by the Reviewing Party or any aspect thereof. The Company hereby consents to service of process and to appear in any such proceeding. Any determination by the Reviewing Party not challenged by Indemnitee shall be binding on the Company and Indemnitee. The remedy provided for in this Section 4 shall be in addition to any other remedies available to Indemnitee at law or in equity.
(c) Defense to Indemnification, Burden of Proof, and Presumptions . It shall be a defense to any action brought by Indemnitee against the Company to enforce this Agreement (other than an action brought to enforce a claim for Expenses or Defense Costs incurred in defending a Proceeding in advance of its final disposition where the required undertaking has been tendered to the Company) that it is not permissible under applicable law for the Company to indemnify Indemnitee for the amount claimed. In connection with any such action or any determination by the Reviewing Party or otherwise as to whether Indemnitee is entitled to be indemnified hereunder, the burden of proving such a defense or determination shall be on the Company. Neither the failure of the Reviewing Party or the Company (including its Board, independent legal counsel, or its stockholders) to have made a determination prior to the commencement of such action by Indemnitee that indemnification of the claimant is proper under the circumstances because Indemnitee has met the standard of conduct set forth in applicable law, nor
 
6

an actual determination by the Reviewing Party or Company (including its Board, independent legal counsel, or its stockholders) that the Indemnitee had not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the Indemnitee has not met the applicable standard of conduct. For purposes of this Agreement, to the fullest extent permitted by law, the termination of any claim, action, suit, or proceeding, by judgment, order, settlement (whether with or without court approval), conviction, or upon a plea of nolo contendere, or its equivalent, shall not, of itself, create a presumption that Indemnitee did not meet any particular standard of conduct or have any particular belief or that a court has determined that indemnification is not permitted by applicable law.
5. Indemnification for Expenses Incurred in Enforcing Rights . The Company shall indemnify Indemnitee against any and all out-of-pocket expenses that are incurred by Indemnitee in connection with any action brought by Indemnitee for
(a) indemnification or advance payment of Expenses (in the case of a Type 1 Indemnifiable Event) or Defense Costs (in the case of a Type 2 Indemnifiable Event) by the Company under this Agreement or any other agreement or under applicable law or the Company’s Articles of Association now or hereafter in effect relating to indemnification for Indemnifiable Events, and/or
(b) recovery under directors’ and officers’ liability insurance policies maintained by the Company,
but only in the event that Indemnitee ultimately is determined to be entitled to such indemnification or insurance recovery, as the case may be. In addition, the Company shall, if so requested by Indemnitee, advance such out-of-pocket expenses to Indemnitee, subject to and in accordance with Section 2(c).
6. Notification and Defense of Proceeding .
(a) Notice . Promptly after receipt by Indemnitee of notice of the commencement of any Proceeding, Indemnitee shall, if a claim in respect thereof is to be made against the Company under this Agreement, notify the Company of the commencement thereof; but the omission so to notify the Company will not relieve the Company from any liability that it may have to Indemnitee, except as provided in Section 6(c).
(b) Defense . This Section 6(b) shall apply only to Type 1 Indemnifiable Events. With respect to any Proceeding as to which Indemnitee notifies the Company of the commencement thereof, the Company will be entitled to participate in the Proceeding at its own expense and, except as otherwise provided below, to the extent the Company so wishes, it may assume the defense thereof with counsel reasonably satisfactory to Indemnitee. After notice from the Company to Indemnitee of its election to assume the defense of any Proceeding, the Company shall not be liable to Indemnitee under this Agreement or otherwise for any Expenses subsequently incurred by Indemnitee in connection with the defense of such Proceeding other than reasonable
 
7

costs of investigation or as otherwise provided below. Indemnitee shall have the right to employ legal counsel in such Proceeding, but all Expenses related thereto incurred after notice from the Company of its assumption of the defense shall be at Indemnitee’s expense unless: (i) the employment of legal counsel by Indemnitee has been authorized by the Company, (ii) Indemnitee has reasonably determined that there may be a conflict of interest between Indemnitee and the Company in the defense of the Proceeding, (iii) after a Change in Control (other than a Change in Control approved by a majority of the directors on the Board who were directors immediately prior to such Change in Control), the employment of counsel by Indemnitee has been approved by the Independent Counsel, or (iv) the Company shall not in fact have employed counsel to assume the defense of such Proceeding, in each of which cases all Expenses of the Proceeding shall be borne by the Company. The Company shall not be entitled to assume the defense of any Proceeding brought by or on behalf of the Company or as to which Indemnitee shall have made the determination provided for in (ii), (iii) and (iv) above.
(c) Settlement of Claims . The Company shall not be liable to indemnify Indemnitee under this Agreement or otherwise for any amounts paid in settlement of any Proceeding effected without the Company’s written consent, such consent not to be unreasonably withheld; provided, however, that if a Change in Control has occurred (other than a Change in Control approved by a majority of the directors on the Board who were directors immediately prior to such Change in Control), the Company shall be liable for indemnification of Indemnitee for amounts paid in settlement if the Independent Counsel has approved the settlement. The Company shall not settle any Proceeding in any manner that would impose any penalty or limitation on Indemnitee without Indemnitee’s written consent. The Company shall not be liable to indemnify the Indemnitee under this Agreement with regard to any judicial award if the Company was not given a reasonable and timely opportunity, at its expense, to participate in the defense of such action; the Company’s liability hereunder shall not be excused if participation in the Proceeding by the Company was barred by this Agreement.
7. Establishment of Trust . In the event of a Change in Control (other than a Change in Control approved by a majority of the directors on the Board who were directors immediately prior to such Change in Control) the Company shall, upon written request by Indemnitee, create a Trust for the benefit of the Indemnitee and from time to time upon written request of Indemnitee shall fund the Trust in an amount sufficient to satisfy any and all Expenses (in the case of a Type 1 Indemnifiable Event) or Defense Costs (in the case of a Type 2 Indemnifiable Event) reasonably anticipated at the time of each such request to be incurred in connection with investigating, preparing for, participating in, and/or defending any Proceeding relating to an Indemnifiable Event. The amount or amounts to be deposited in the Trust pursuant to the foregoing funding obligation shall be determined by the Independent Counsel. The terms of the Trust shall provide that (i) the Trust shall not be revoked or the principal thereof invaded without the written consent of the Indemnitee, (ii) the Trustee shall advance, within ten business days of a request by the Indemnitee, any and all Expenses (in the case of a Type 1 Indemnifiable Event) or Defense Costs (in the case of a Type 2 Indemnifiable Event) to the Indemnitee (and the Indemnitee hereby agrees to reimburse the Trust under the same circumstances for which the Indemnitee would be required to reimburse the Company under Section 2(c) of this Agreement), (iii) the Trust shall continue to be funded by the Company in
 
8

accordance with the funding obligation set forth above, (iv) the Trustee shall promptly pay to the Indemnitee all amounts for which the Indemnitee shall be entitled to indemnification pursuant to this Agreement or otherwise, and (v) all unexpended funds in the Trust shall revert to the Company upon a final determination by the Independent Counsel or a court of competent jurisdiction, as the case may be, that the Indemnitee has been fully indemnified under the terms of this Agreement. The Trustee shall be chosen by the Indemnitee. Nothing in this Section 7 shall relieve the Company of any of its obligations under this Agreement. All income earned on the assets held in the Trust shall be reported as income by the Company for federal, state, local, and foreign tax purposes. The Company shall pay all costs of establishing and maintaining the Trust and shall indemnify the Trustee against any and all expenses (including attorneys’ fees), claims, liabilities, loss, and damages arising out of or relating to this Agreement or the establishment and maintenance of the Trust.
8. Non-Exclusivity . The rights of Indemnitee hereunder shall be in addition to any other rights Indemnitee may have under the Company’s Articles of Association, applicable law, or otherwise; provided, however, that this Agreement shall supersede any prior indemnification agreement between the Company and the Indemnitee. To the extent that a change in applicable law (whether by statute or judicial decision) permits greater indemnification than would be afforded currently under the Company’s Articles of Association, applicable law, or this Agreement, it is the intent of the parties that Indemnitee enjoy by this Agreement the greater benefits so afforded by such change.
9. Liability Insurance . To the extent the Company maintains an insurance policy or policies providing general and/or directors’ and officers’ liability insurance, Indemnitee shall be covered by such policy or policies, in accordance with its or their terms, to the maximum extent of the coverage available for any Company director or officer.
10. Continuation of Contractual Indemnity or Period of Limitations . All agreements and obligations of the Company contained herein shall continue for so long as Indemnitee shall be subject to, or involved in, any proceeding for which indemnification is provided pursuant to this Agreement. Notwithstanding the foregoing, no legal action shall be brought and no cause of action shall be asserted by or on behalf of the Company or any Affiliate of the Company against Indemnitee, Indemnitee’s spouse, heirs, executors, or personal or legal representatives after the expiration of two years from the date of accrual of such cause of action, or such longer period as may be required by Cayman Islands law under the circumstances. Any claim or cause of action of the Company or its Affiliate shall be extinguished and deemed released unless asserted by the timely filing and notice of a legal action within such period; provided, however, that if any shorter period of limitations is otherwise applicable to any such cause of action, the shorter period shall govern.
11. Amendment of this Agreement . No supplement, modification, or amendment of this Agreement shall be binding unless executed in writing by both of the parties hereto. No waiver of any of the provisions of this Agreement shall be binding unless in the form of a writing signed by the party against whom enforcement of the waiver is sought, and no such waiver shall operate as a waiver of any other provisions hereof (whether or not similar), nor shall such waiver constitute a continuing waiver. Except as specifically provided herein, no failure to exercise or any delay in exercising any right or remedy hereunder shall constitute a waiver thereof.
 
9

12. Subrogation . In the event of payment under this Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee, who shall execute all papers required and shall do everything that may be necessary to secure such rights, including the execution of such documents necessary to enable the Company effectively to bring suit to enforce such rights.
13. No Duplication of Payments . The Company shall not be liable under this Agreement to make any payment in connection with any claim made against Indemnitee to the extent Indemnitee has otherwise received payment (under any insurance policy, Articles of Association, or otherwise) of the amounts otherwise indemnifiable hereunder.
14. Binding Effect . This Agreement shall be binding upon and inure to the benefit of and be enforceable by the parties hereto and their respective successors (including any direct or indirect successor by purchase, merger, consolidation, or otherwise to all or substantially all of the business and/or assets of the Company), assigns, spouses, heirs, and personal and legal representatives. The Company shall require and cause any successor (whether direct or indirect by purchase, merger, consolidation, or otherwise) to all, substantially all, or a substantial part, of the business and/or assets of the Company, by written agreement in form and substance satisfactory to Indemnitee, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform if no such succession had taken place. The indemnification provided under this Agreement shall continue as to Indemnitee for any action taken or not taken while serving in an indemnified capacity pertaining to an Indemnifiable Event even though he may have ceased to serve in such capacity at the time of any Proceeding.
15. Severability . If any provision (or portion thereof) of this Agreement shall be held by a court of competent jurisdiction to be invalid, void, or otherwise unenforceable, the remaining provisions shall remain enforceable to the fullest extent permitted by law. Furthermore, to the fullest extent possible, the provisions of this Agreement (including, without limitation, each portion of this Agreement containing any provision held to be invalid, void, or otherwise unenforceable, that is not itself invalid, void, or unenforceable) shall be construed so as to give effect to the intent manifested by the provision held invalid, void, or unenforceable.
16. Governing Law . This Agreement shall be governed by and construed and enforced in accordance with the laws of New York applicable to contracts made and to be performed in such State without giving effect to its principles of conflicts of laws.
17. Notices . All notices, demands, and other communications required or permitted hereunder shall be made in writing and shall be deemed to have been duly given if delivered by hand, against receipt, or mailed, postage prepaid, certified or registered mail, return receipt requested, and addressed to the Company at:

16.5 [Intentionally Deleted] . 
SECTION 2. Representations and Warranties . Each Obligor represents and warrants as follows:
2.1 Authorization . The execution, delivery and performance by such Obligor of this Amendment are within its corporate powers, have been duly authorized by all necessary action, and do not: (i) contravene its organizational documents or any contractual restriction, law or governmental regulation or court decree or order that is binding on such Obligor or (iii) require any consent, approval, authorization or other action by, or notice to, or registration or filing with, any governmental authority or other Person.
