THE CHUBB CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1) General

The accompanying condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) and include the accounts of The Chubb Corporation (Chubb) and its subsidiaries (collectively, the Corporation). Significant intercompany transactions have been eliminated in consolidation.

The amounts included in this report are unaudited but include those adjustments, consisting of normal recurring items, that management considers necessary for a fair presentation. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes in the Notes to Consolidated Financial Statements included in Chubb's Annual Report on Form 10-K for the year ended December 31, 2014.

2) Merger Agreement with ACE Limited

On June 30, 2015, Chubb entered into an Agreement and Plan of Merger (Merger Agreement), with ACE Limited (ACE), a company organized under the laws of Switzerland, and William Investment Holdings Corporation (Merger Sub), a New Jersey corporation and a wholly owned indirect subsidiary of ACE, pursuant to which Merger Sub will merge with and into Chubb, with Chubb surviving as a wholly owned indirect subsidiary of ACE (the Merger). At the effective time of the Merger, each share (except for certain shares held by ACE, Chubb or their subsidiaries) of common stock of Chubb, par value $1.00 per share, will be converted into the right to receive 0.6019 of a common share of ACE, par value CHF 24.15 per share, and $62.93 in cash.

The Board of Directors of Chubb (the Board) unanimously approved the Merger Agreement and the transactions contemplated thereby, including the Merger. The closing of the Merger is subject to the approval of the Merger Agreement by the affirmative vote of two-thirds of the votes cast by Chubb shareholders at a special Chubb shareholder meeting. The closing of the Merger is also subject to various customary conditions, including approval by ACE shareholders of certain matters and receipt of required governmental approvals, including insurance regulatory approvals and the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. The transaction is expected to close during the first quarter of 2016.

The Merger Agreement contains certain termination rights for both Chubb and ACE and further provides that, upon termination under specified circumstances, Chubb would be required to pay to ACE a termination fee of $930 million. No such termination fee has been accrued as of June 30, 2015.

Table of Contents

Page 7

Pursuant to the Merger Agreement, until the effective time of the Merger or termination of the Merger Agreement, the Corporation is required to conduct its business in the ordinary course in all material respects and, without the prior written consent of ACE, cannot take certain actions, except in each case as permitted pursuant to the Merger Agreement.

3) Accounting Pronouncements Not Yet Adopted

In February 2015, the Financial Accounting Standards Board issued updated guidance that amends certain aspects of the current consolidation accounting guidance. In particular, the new guidance modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities (VIEs) or voting interest entities and eliminates the presumption that a general partner should consolidate a limited partnership. The new guidance would be effective for the Corporation for the year beginning January 1, 2016. The Corporation is in the process of assessing the effect, if any, that the implementation of this guidance will have on its financial position and results of operations.

Actual maturities could differ from contractual maturities because borrowers may have the right to call or prepay obligations.

The Corporation's equity securities comprise a diversified portfolio of primarily U.S. publicly-traded common stocks.

The Corporation is involved in the normal course of business with VIEs primarily as a passive investor in residential mortgage-backed securities, commercial mortgage-backed securities and private equity limited partnerships issued by third party VIEs. The Corporation is not the primary beneficiary of these VIEs. The Corporation's maximum exposure to loss with respect to these investments is limited to the investment carrying values included in the Corporation's consolidated balance sheet and any unfunded partnership commitments.

At June 30, 2015, approximately 1,330 individual fixed maturities and 20 individual equity securities were in an unrealized loss position. The Corporation does not have the intent to sell and it is not more likely than not that the Corporation will be required to sell these fixed maturities before the securities recover to their amortized cost value. In addition, the Corporation believes that none of the declines in the fair values of these fixed maturities relate to credit losses. The Corporation has the intent and ability to hold the equity securities in an unrealized loss position for a period of time sufficient to allow for the recovery of cost. The Corporation believes that none of the declines in the fair value of these fixed maturities and equity securities were other than temporary at June 30, 2015.

5) Comprehensive Income

Comprehensive income is defined as all changes in shareholders' equity, except those arising from transactions with shareholders. Comprehensive income includes net income and other comprehensive income or loss, which for the Corporation consists of changes in unrealized appreciation or depreciation of investments carried at fair value, changes in unrealized other-than-temporary impairment losses of fixed maturities, changes in postretirement benefit costs not yet recognized in net income and changes in foreign currency translation gains or losses.

6) Segments Information

The principal business of the Corporation is the sale of property and casualty insurance. The profitability of the property and casualty insurance business depends on the results of both underwriting operations and investments, which are viewed as two distinct operations. The underwriting operations are managed and evaluated separately from the investment function.

The property and casualty insurance subsidiaries underwrite most lines of property and casualty insurance. Underwriting operations consist of four separate business units: personal insurance, commercial insurance, specialty insurance and reinsurance assumed. The personal segment targets the personal insurance market. The personal classes include automobile, homeowners and other personal coverages. The commercial segment includes those classes of business that are generally available in broad markets and are of a more commodity nature. Commercial classes include multiple peril, casualty, workers' compensation and property and marine. The specialty segment includes those classes of business that are available in more limited markets since they require specialized underwriting and claim settlement. Specialty classes include professional liability coverages and surety. The reinsurance assumed business has been in runoff since the transfer of the ongoing reinsurance assumed business to a reinsurance company in 2005.

Corporate and other includes investment income earned on corporate invested assets, corporate expenses and the results of the Corporation's non-insurance subsidiaries.

7) Fair Values of Financial Instruments

Fair values of financial instruments are determined by management using valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. Fair values are generally measured using quoted prices in active markets for identical assets or liabilities or other inputs, such as quoted prices for similar assets or liabilities, that are observable, either directly or indirectly. In those instances where observable inputs are not available, fair values are measured using unobservable inputs for the asset or liability. Unobservable inputs reflect the Corporation's own assumptions about the assumptions that market participants would use in pricing the asset or liability and are developed based on the best information available in the circumstances. Fair value estimates derived from unobservable inputs are affected by the assumptions used, including the discount rates and the estimated amounts and timing of future cash flows. The derived fair value estimates cannot be substantiated by comparison to independent markets and are not necessarily indicative of the amounts that would be realized in a current market exchange. Certain financial instruments, particularly insurance contracts, are excluded from fair value disclosure requirements.

The methods and assumptions used to estimate the fair values of financial instruments are as follows:

(i) The carrying value of short term investments approximates fair value due to the short maturities of these investments.

(ii) Fair values of fixed maturities are determined by management, utilizing prices obtained from a third party, nationally recognized pricing service or, in the case of securities for which prices are not provided by a pricing service, from third party brokers. For fixed maturities that have quoted prices in active markets, market quotations are provided. For fixed maturities that do not trade on a daily basis, the pricing service and brokers provide fair value estimates using a variety of inputs including, but not limited to, benchmark yields, reported trades, broker/dealer quotes, issuer spreads, bids, offers, reference data, prepayment rates and measures of volatility. Management reviews on an ongoing basis the reasonableness of the methodologies used by the relevant pricing service and brokers. In addition, management, using the prices received for the securities from the pricing service and brokers, determines the aggregate portfolio price performance and reviews it against applicable indices. If management believes that significant discrepancies exist, it will discuss these with the relevant pricing service or broker to resolve the discrepancies.

(iii) Fair values of equity securities are determined by management, utilizing quoted market prices.

(iv) Fair values of long term debt issued by Chubb are determined by management, utilizing prices obtained from a third party, nationally recognized pricing service.

At June 30, 2015 and December 31, 2014, a pricing service provided fair value amounts for approximately 99% of the Corporation's fixed maturities. The prices obtained from a pricing service and brokers generally are non-binding, but are reflective of current market transactions in the applicable financial instruments.

At June 30, 2015 and December 31, 2014, the Corporation held an insignificant amount of financial instruments in its investment portfolio for which a lack of market liquidity impacted the determination of fair value.

The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels as follows:

Level 1 – Unadjusted quoted prices in active markets for identical financial instruments.

Level 2 – Other inputs that are observable for the financial instrument, either directly or indirectly.

Level 3 – Significant unobservable inputs.

Item 2 - Management's Discussion and Analysis of Financial Condition and Results of Operations

Management's Discussion and Analysis of Financial Condition and Results of Operations (MD&A) addresses the financial condition of the Corporation as of June 30, 2015 compared with December 31, 2014 and the results of operations for the six months and three months ended June 30, 2015 and 2014. This discussion should be read in conjunction with the condensed consolidated financial statements and related notes contained in this report and the consolidated financial statements and related notes and management's discussion and analysis of financial condition and results of operations included in Chubb's Annual Report on Form 10-K for the year ended December 31, 2014.

Critical Accounting Estimates and Judgments

The consolidated financial statements include amounts based on informed estimates and judgments of management for transactions that are not yet complete. Such estimates and judgments affect the reported amounts in the financial statements. Those estimates and judgments that were most critical to the preparation of the financial statements involved the determination of loss reserves and the recoverability of related reinsurance recoverables and the evaluation of whether a decline in value of any investment is temporary or other than temporary. These estimates and judgments, which are discussed in Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2014 as supplemented within the following analysis of our results of operations, require the use of assumptions about matters that are highly uncertain and therefore are subject to change as facts and circumstances develop. If different estimates and judgments had been applied, materially different amounts might have been reported in the financial statements.

Overview

The following highlights do not address all of the matters covered in the other sections of Management's Discussion and Analysis of Financial Condition and Results of Operations or contain all of the information that may be important to Chubb's shareholders or the investing public. This overview should be read in conjunction with the other sections of Management's Discussion and Analysis of Financial Condition and Results of Operations.

Net income was $869 million in the first six months of 2015 and $494 million in the second quarter compared with $948 million and $499 million, respectively, in the same periods of 2014. The lower net income in the first six months and second quarter of 2015 compared with the same periods of 2014 was due to lower net realized investment gains, offset in part by higher operating income.

Operating income, which we define as net income excluding realized investment gains and losses after tax, was $848 million in the first six months of 2015 and $481 million in the second quarter compared with $792 million and $418 million, respectively, in the same periods of 2014. The higher operating income in the first six months and second quarter of 2015 was due to higher underwriting income in our property and casualty insurance business, offset in part by lower property and casualty investment income. Management uses operating income, a non-GAAP financial measure, among other measures, to evaluate its performance because the realization of investment gains and losses in any period could be discretionary as to timing and can fluctuate significantly, which could distort the analysis of operating trends.

Underwriting results were profitable in the first six months and second quarter of 2015 and 2014, but more so in the 2015 periods. The combined loss and expense ratio was 89.7% in the first six months of 2015 and 85.5% in the second quarter compared with 91.6% and 90.0%, respectively, in the same periods of 2014. The 1.9 percentage point decrease in the combined loss and expense ratio in the first six months of 2015 compared with the same period of 2014 was due to a lower current accident year loss ratio excluding catastrophes, offset in part by a higher impact of catastrophes and a lower amount of favorable prior year loss development. The 4.5 percentage point decrease in the combined loss and expense ratio in the second quarter of 2015 compared with the same period of 2014 was due to a lower current accident year loss ratio excluding catastrophes and, to a lesser extent, a higher amount of favorable prior year loss development and a lower expense ratio. The impact of catastrophes accounted for 6.4 percentage points of the combined ratio in the first six months of 2015 and 4.7 percentage points in the second quarter compared with 5.7 and 4.8 percentage points, respectively, in the same periods of 2014.

In the first six months and second quarter of 2015, we estimate that we experienced overall favorable development of about $295 million and $185 million, respectively, on net loss reserves established as of the previous year end. We estimate that in the first six months and second quarter of 2014, we experienced overall favorable prior year loss development of about $325 million and $165 million, respectively. In the first six months and second quarter of both years we experienced favorable prior year loss development in each segment of our insurance business, but more so in our commercial and specialty insurance segments.

Total net premiums written increased by 2% in the first six months of 2015 and 3% in the second quarter compared with the same periods of 2014. The growth in net premiums written in the first six months and second quarter of 2015 was negatively impacted by foreign currency translation, reflecting the impact of the stronger U.S. dollar relative to several currencies in which we wrote business outside the United States in the 2015 periods compared with the same periods of 2014. In the first six months of 2015, net premiums written outside the United States represented 23% of our total net premiums written. Total net premiums written excluding the effect of foreign currency translation increased by 5% in the first six months and second quarter of 2015. Net premiums written in the United States increased by 5% in the first six months of 2015 and 6% in the second quarter. Net premiums written outside the United States decreased by 7% in the first six months of 2015 and 9% in the second quarter, when measured in U.S. dollars. Excluding the effect of foreign currency translation, such premiums increased by 4% in the first six months of 2015 and 2% in the second quarter. Management uses growth in net premiums written excluding the effect of foreign currency translation, a non-GAAP financial measure, to evaluate the trends in net premiums written, exclusive of the effect of fluctuations in exchange rates between the U.S. dollar and the foreign currencies in which business is transacted. The impact of foreign currency translation is excluded as exchange rates may fluctuate significantly and the effect of fluctuations could distort the analysis of trends. When excluding the effect of foreign currency translation on growth, management uses the current period average exchange rates to translate both the current period and the prior period foreign currency denominated net premiums written amounts.

Property and casualty investment income before taxes decreased by 6% in the first six months of 2015 and 5% in the second quarter compared with the same periods of 2014. Property and casualty investment income after tax decreased by 5% in the first six months of 2015 and 4% in the second quarter compared with the same periods of 2014. The decreases in both periods of 2015 were due to a decline in the average yield on our investment portfolio and, to a lesser extent, the effect of foreign currency translation. Management uses property and casualty investment income after tax, a non-GAAP financial measure, to evaluate its investment results because it reflects the impact of any change in the proportion of tax exempt investment income to total investment income and is therefore more meaningful for analysis purposes than investment income before income tax.

Table of Contents

Page 26

Net realized investment gains before tax were $31 million ($21 million after tax) in the first six months of 2015 and $20 million ($13 million after tax) in the second quarter compared with $241 million ($156 million after tax) and $125 million ($81 million after tax), respectively, in the same periods of 2014. The net realized investment gains in the first six months and second quarter of 2015 were primarily related to investments in limited partnerships, which generally are reported on a one quarter lag, and, to a lesser extent, sales of fixed maturities. The net realized investment gains in the first six months of 2014 were primarily related to investments in limited partnerships, sales of equity securities and, to a lesser extent, sales of fixed maturity securities. The net realized investment gains in the second quarter of 2014 were primarily related to investments in limited partnerships, sales of fixed maturity securities and, to a lesser extent, sales of equity securities.

On June 30, 2015, Chubb entered into an Agreement and Plan of Merger (Merger Agreement) with ACE, a company organized under the laws of Switzerland, and William Investment Holdings Corporation (Merger Sub), a New Jersey corporation and a wholly owned indirect subsidiary of ACE, pursuant to which Merger Sub will merge with and into Chubb, with Chubb surviving as a wholly owned indirect subsidiary of ACE (the Merger). At the effective time of the Merger, each share (except for certain shares held by ACE, Chubb or their subsidiaries) of common stock of Chubb, par value $1.00 per share, will be converted into the right to receive 0.6019 of a common share of ACE, par value CHF 24.15 per share, and $62.93 in cash. The transaction is expected to close during the first quarter of 2016, subject to approval by Chubb shareholders and the satisfaction of various customary closing conditions. The Merger Agreement is discussed further in Note (2) of the Notes to Consolidated Financial Statements.

Property and casualty income before tax was higher in the first six months and second quarter of 2015 compared with the same periods of 2014, due to higher underwriting income, offset in part by lower investment income. The higher underwriting income in the first six months of 2015 compared with the same period of 2014 was due to a lower current accident year loss ratio excluding catastrophes, offset in part by a higher impact of catastrophes and a lower amount of favorable prior year loss development. The higher underwriting income in the second quarter of 2015 compared with the same period of 2014 was due to a lower current accident year loss ratio excluding catastrophes and, to a lesser extent, a higher amount of favorable prior year loss development and a lower expense ratio. The lower investment income in the first six months and second quarter of 2015 compared with the same periods of 2014 was due to a decline in the average yield on our investment portfolio and, to a lesser extent, the effect of foreign currency translation.

The profitability of our property and casualty insurance business depends on the results of both our underwriting and investment operations. We view these as two distinct operations since the underwriting functions are managed separately from the investment function. Accordingly, in assessing our performance, we evaluate underwriting results separately from investment results.

Underwriting Results

We evaluate the underwriting results of our property and casualty insurance business in the aggregate and for each of our business units.

Net Premiums Written

Net premiums written were $6.4 billion in the first six months of 2015 and $3.3 billion in the second quarter compared with $6.3 billion and $3.2 billion, respectively, in the same periods of 2014. Net premiums written by business unit were as follows:

* The change in net premiums written is not presented for this business unit since it is in runoff.

Net premiums written increased by 2% in the first six months of 2015 and 3% in the second quarter compared with the same periods of 2014 as a result of growth in premiums written in the United States. The growth in net premiums written in the first six months and second quarter of 2015 was negatively impacted by foreign currency translation, reflecting the impact of the stronger U.S. dollar relative to several currencies in which we wrote business outside the United States in the 2015 periods compared with the same periods of 2014. Net premiums written excluding the effect of foreign currency translation increased by 5% in the first six months and second quarter of 2015. Net premiums written in the United States, which in the first six months of 2015 represented 77% of our total net premiums written, increased by 5% in the first six months of 2015 and 6% in the second quarter. Net premiums written outside the United States decreased by 7% in the first six months of 2015 and 9% in the second quarter, when measured in U.S. dollars. Excluding the effect of foreign currency translation, net premiums written outside the United States increased by 4% in the first six months of 2015 and 2% in the second quarter.

We classify business as written inside or outside the United States based on the location of the risks associated with the underlying policies. The method of determining location of risk varies by class of business. Location of risk for property classes is typically based on the physical location of the covered property, while location of risk for liability classes may be based on the main location of the insured, or in the case of the workers' compensation class, the primary work location of the covered employee.

Net premiums written in the United States grew in each segment of our business in the first six months and second quarter of 2015 compared with the same periods of 2014, with the most significant growth occurring in our personal insurance and commercial insurance segments. Growth in the United States in our personal insurance segment reflected higher insured exposures, higher rates upon renewal, strong retention of existing business, and new business. Growth in the United States in our commercial insurance segment and our professional liability business, which is the predominant component of our specialty insurance segment, reflected high retention of existing business, new business, as well as renewal rate increases.

Average renewal rates in the United States in our personal insurance segment were up slightly in the first six months and second quarter of 2015 compared with expiring rates. The amounts of coverage purchased or the insured exposures, both of which are bases upon which we calculate the premiums we charge, were up modestly in the United States in the first six months and second quarter of 2015. Retention levels in our personal insurance segment in the United States remained strong in the first six months and second quarter of 2015. The level of new business in the United States in our personal insurance business in the first six months and second quarter of 2015 was similar to the same periods of 2014.

Average renewal rates in the United States in the first six months and second quarter of 2015 were up slightly in our commercial insurance segment and up modestly in our professional liability business compared with expiring rates. On average, the amounts of coverage purchased or the insured exposures upon renewal were flat in our commercial insurance segment in the United States in the first six months and second quarter of 2015. Such amounts were up slightly in our professional liability business in the first six months and second quarter of 2015. We continued to retain a high percentage of our existing commercial insurance and professional liability business in the United States in the first six months and second quarter of 2015. Retention levels in the first six months and second quarter of 2015 were modestly higher in our commercial insurance segment and slightly higher in our professional liability business compared with the same periods of 2014. As portions of our business have approached rate adequacy due to pricing and underwriting actions over the past several years, the level of renewal rate increases has moderated and we have achieved higher retention levels. The level of new business in the United States was up in our commercial insurance segment in the first six months of 2015 and flat in the second quarter compared with the same periods of 2014. In our professional liability business, the level of new business in the United States was up in both periods of 2015, but more so in the six month period.

The decrease in net premiums written outside the United States in the first six months and second quarter of 2015 compared with the same periods of 2014 reflected a modest decrease in our commercial insurance segment and a more significant decrease in our personal insurance and specialty insurance segments. Net premiums written outside the United States excluding the effect of foreign currency translation increased by 4% in the first six months of 2015, with modest growth occurring in our personal insurance and specialty insurance segments and more significant growth in our commercial insurance segment. In the second quarter of 2015, net premiums written outside the United States excluding the effect of foreign currency translation increased by 2%, with a significant increase in our commercial insurance segment, a modest increase in our specialty insurance segment and a modest decrease in our personal insurance segment.

Average renewal rates outside the United States in our personal insurance segment were higher in the first six months and second quarter of 2015 compared with expiring rates, driven particularly by the automobile class.

Average renewal rates outside the United States were flat in both our commercial insurance segment and professional liability business in the first six months of 2015 and up slightly in the second quarter compared with expiring rates. On average, the amounts of coverage purchased or the insured exposures upon renewal were flat in both our commercial insurance segment and professional liability business outside the United States in the first six months of 2015. Such amounts were up slightly in our commercial insurance segment and close to flat in our professional liability business in the second quarter of 2015. We continued to retain a high percentage of our existing commercial and professional liability business outside the United States in the first six months and second quarter of 2015. Retention levels in the first six months of 2015 were up slightly in our commercial insurance segment and professional liability business compared with the same period of 2014. Retention levels in the second quarter of 2015 compared with the same period of 2014 were up modestly in our commercial insurance segment and up slightly in our professional liability business. The level of new business outside the United States in the first six months of 2015 compared with the same period of 2014 was modestly higher in our commercial insurance segment and lower in our professional liability business. The level of new business outside the United States in the second quarter of 2015 compared with the same period of 2014 was lower in both our commercial insurance segment and professional liability business.

We expect that during the remainder of 2015 market conditions will remain competitive and average renewal rate increases in some classes of business will be at lower levels than those achieved in 2014.

Ceded Reinsurance

Our premiums written are net of amounts ceded to reinsurers who assume a portion of the risk under the insurance policies we write that are subject to reinsurance.

The most significant component of our ceded reinsurance program is property reinsurance. We purchase two main types of property reinsurance: catastrophe and property per risk.

Table of Contents

Page 31

For property risks in the United States and Canada we purchase traditional catastrophe reinsurance, including our primary treaty, which we refer to as the North American catastrophe treaty, as well as supplemental catastrophe reinsurance that provides additional coverage for our exposures in the northeast United States. For certain exposures in the United States, we have also arranged for the purchase of reinsurance funded through the issuance of multi–year, collateralized risk-linked securities, known as catastrophe bonds. For events outside the United States, we also purchase traditional catastrophe reinsurance.

We renewed our primary traditional property catastrophe treaties and our commercial property per risk treaty in April 2015 with limit structures similar to the expiring treaties and with modest enhancements in coverage, as well as in terms and conditions. The supplemental catastrophe reinsurance that provides coverage for our exposures in the northeast United States remains in effect until June 2016. In March 2015, we arranged for the purchase of reinsurance through the issuance of a catastrophe bond to replace the portion of a catastrophe bond that expired in March 2015.

The North American catastrophe treaty has an initial retention of $500 million and provides coverage for exposures in the United States and Canada of approximately 34% of losses (net of recoveries from other available reinsurance) between $500 million and $900 million and approximately 75% of losses (net of recoveries from other available reinsurance) between $900 million and $1.75 billion. For certain catastrophic events in the northeast United States or along the southern U.S. coastline, the combination of the North American catastrophe treaty, the supplemental catastrophe reinsurance and/or the catastrophe bond arrangements provides additional coverage as discussed below.

The catastrophe bond arrangements provide reinsurance coverage for specific types of losses in specific geographic locations. They are generally designed to supplement coverage provided under the North American catastrophe treaty. We currently have three catastrophe bond arrangements in effect that expire between 2016 and 2020. We have a $150 million arrangement that expires in March 2016 that provides reinsurance coverage for our exposure to homeowners-related hurricane and severe thunderstorm losses in eight states along the southern U.S. coastline. We have a $270 million arrangement that expires in March 2018. We also have a $250 million arrangement that incepted in March 2015 and expires in March 2020, which replaced a $250 million arrangement that expired in March 2015. Both of the latter two catastrophe bond arrangements provide reinsurance coverage for our exposure to homeowners and commercial losses related to certain perils, including hurricanes and other named storms, earthquakes, severe thunderstorms and winter storms in 12 states in the northeast United States and the District of Columbia.

For the indicated catastrophic events in the northeast United States, the combination of the North American catastrophe treaty, the supplemental catastrophe reinsurance, and the $270 million and $250 million catastrophe bond arrangements provides additional coverage of approximately 63% of losses (net of recoveries from other available reinsurance) between $1.75 billion and $3.67 billion.

Page 32

For hurricane and severe thunderstorm events along the southern U.S. coastline, the $150 million catastrophe bond arrangement provides additional coverage of approximately 45% of homeowners-related hurricane and severe thunderstorm losses (net of recoveries from other available reinsurance) between $875 million and $1.21 billion.

For hurricane events in Florida, in addition to the coverage provided by the North American catastrophe treaty and the $150 million catastrophe bond arrangement discussed above, we have reinsurance from the Florida Hurricane Catastrophe Fund, which is a state-mandated fund designed to reimburse insurers for a portion of their residential catastrophe-related hurricane losses. Our participation in this program, for which the most recent annual period began on June 1, 2015, provides coverage of 90% of homeowners-related hurricane losses in Florida in excess of our initial retention of $145 million per event. Under the terms of the program, our aggregate recoveries during the annual coverage period are limited to approximately $365 million, based on our current level of participation.

Our primary property catastrophe treaty for events outside the continental United States, including Canada, provides coverage of approximately 75% of losses (net of recoveries from other available reinsurance) between $100 million and $350 million. For catastrophic events in Australia and Canada, additional reinsurance provides coverage of 80% of losses (net of recoveries from other available reinsurance) between $350 million and $475 million.

Our commercial property per risk treaty provides coverage for property exposures both inside and outside the United States. Depending upon the currency in which the covered insurance policy was issued and prevailing foreign currency exchange rates, the treaty provides coverage per risk of approximately $475 million to $685 million in excess of our initial retention, which is generally between $20 million and $25 million.

In addition to our major property catastrophe and property per risk treaties, we purchase several smaller property treaties that provide coverage for specific classes of business or locations having concentrations of risk.

Recoveries under our property reinsurance treaties are subject to certain coinsurance requirements that affect the interaction of some elements of our reinsurance program.

Our property reinsurance treaties generally contain terrorism exclusions for acts perpetrated by foreign terrorists, and for nuclear, biological, chemical and radiological loss causes, whether such acts are perpetrated by foreign or domestic terrorists.

The renewal rates associated with the North American catastrophe treaty, the catastrophe treaty that covers events outside the United States and the commercial property per risk treaty were lower than the rates for the expiring treaties. The costs related to the reinsurance purchased through the issuance of the catastrophe bond in March 2015 were also lower than those related to the expiring bond. We therefore expect that the overall cost of our property reinsurance program will be lower in 2015 than in 2014.

Profitability

The combined loss and expense ratio (or combined ratio), expressed as a percentage, is the key measure of underwriting profitability traditionally used in the property and casualty insurance business. Management evaluates the performance of our underwriting operations and of each of our business units using, among other measures, the combined loss and expense ratio calculated in accordance with U.S. statutory accounting principles. It is the sum of the ratio of losses and loss expenses to premiums earned (loss ratio) and the ratio of statutory underwriting expenses to premiums written (expense ratio) after reducing both premium amounts by dividends to policyholders. When the combined ratio is under 100%, underwriting results are generally considered profitable; when the combined ratio is over 100%, underwriting results are generally considered unprofitable.

Statutory accounting principles applicable to U.S. property and casualty insurance companies differ in certain respects from generally accepted accounting principles in the United States (GAAP). Under statutory accounting principles, policy acquisition and other underwriting expenses are recognized immediately, not at the time premiums are earned. Management uses underwriting results determined in accordance with GAAP, among other measures, to assess the overall performance of our underwriting operations. To convert statutory underwriting results to a GAAP basis, certain policy acquisition expenses are deferred and amortized over the period in which the related premiums are earned. Underwriting income determined in accordance with GAAP is defined as premiums earned less losses and loss expenses incurred and GAAP underwriting expenses incurred.

An accident year is the calendar year in which a loss is incurred or, in the case of claims-made policies, the calendar year in which a loss is reported. The total losses and loss expenses incurred for a particular calendar year include current accident year losses and loss expenses as well as any increases or decreases to our estimates of losses and loss expenses that occurred in all prior accident years, which we refer to as prior year loss development.

Underwriting results for our property and casualty insurance business were profitable in the first six months and second quarter of 2015 and 2014, but more so in the 2015 periods. The combined loss and expense ratio was as follows:

Periods Ended June 30

Table of Contents

Page 34

The 1.5 percentage point decrease in the loss ratio in the first six months of 2015 compared with the same period of 2014 was due to a lower current accident year loss ratio excluding catastrophes, offset in part by a higher impact of catastrophes and a lower amount of favorable prior year loss development. The 4.0 percentage point decrease in the loss ratio in the second quarter of 2015 compared with the same period of 2014 was due to a lower current accident year loss ratio excluding catastrophes and, to a lesser extent, a higher amount of favorable prior year loss development. The current accident year loss ratio excluding catastrophes was lower in the first six months and second quarter of 2015 in each segment of our insurance business compared with the same periods of 2014. The loss ratio in the first six months and second quarter of 2015 and 2014 included a significant impact from catastrophes. It also reflected favorable loss experience excluding catastrophes that we believe resulted from our disciplined underwriting in recent years. The loss ratio in the first six months and second quarter of both years also benefited from the positive impact of rate increases on premiums earned in most classes of business as well as favorable prior year loss development.

Our underwriting profitability in any given period will be affected by the impact of catastrophes in that period. We define a catastrophe as an event that is estimated to cause $25 million or more in industry-wide insured property losses and affects a significant number of policyholders and insurers.

The net impact of catastrophes in the first six months of 2015 was $398 million, which represented 6.4 percentage points of the combined ratio, compared with $345 million or 5.7 percentage points in the same period of 2014. The net impact of catastrophes in the second quarter of 2015 was $148 million, which represented 4.7 percentage points of the combined ratio, compared with $146 million or 4.8 percentage points in the same period of 2014. Most of the catastrophe losses in the first six months of 2015 and 2014 related to weather-related events in the United States.

The impact of catastrophes, including losses and any related reinsurance reinstatement premiums, for individually significant events and all other events was as follows:

The net impact of catastrophes in the first six months of 2015 and 2014 reflected $15 million and $8 million, respectively, of favorable prior year loss development. Prior year loss development related to catastrophes was insignificant in the second quarter of both years.

The expense ratio decreased by 0.4 of a percentage point in the first six months of 2015 and 0.5 of a percentage point in the second quarter compared with the same periods of 2014, due primarily to growth in net premiums written in both periods of 2015 while overhead expenses were flat in both periods of 2015 compared with the same periods of 2014.

Review of Underwriting Results by Business Unit

Personal Insurance

Net premiums written in our personal insurance segment, which represented 35% of our total net premiums written in the first six months of 2015, increased by 2% in the first six months and second quarter of 2015 compared with the same periods of 2014. Net premiums written for the classes of business within the personal insurance segment were as follows:

Six Months Ended June 30 % Incr. Quarter Ended June 30 % Incr.

The increase in net premiums written in our personal insurance segment in the first six months and second quarter of 2015 compared with the same periods of 2014 was driven by growth in the United States. Premium growth occurred in all classes of this business in the first six months and second quarter of 2015 in the United States. Net premiums written outside the United States decreased in the first six months and second quarter of 2015. In both periods, net premiums written reflected the negative effect of foreign currency translation. Excluding the effect of foreign currency translation, net premiums written outside the United States increased modestly in the first six months of 2015 and decreased modestly in the second quarter compared with the same periods of 2014. The overall growth in our personal insurance segment excluding the effect of foreign currency translation was 5% in the first six months and second quarter of 2015. Such growth reflected higher insured exposures, higher rates upon renewal, strong retention of existing business, and new business.

Page 36

Net premiums written for our personal automobile business decreased in the first six months and second quarter of 2015 compared with the same periods of 2014, driven by a decrease in net premiums written outside the United States, due to the negative effect of foreign currency translation. Personal automobile net premiums written outside the United States represented approximately 35% of our total personal automobile net premiums written in the first six months of 2015, with approximately half of such premiums written in Brazil. Personal automobile net premiums written in the United States increased modestly in the first six months and second quarter of 2015 compared with the same periods of 2014.

Net premiums written for our homeowners business increased in the first six months and second quarter of 2015 compared with the same periods of 2014, due to growth in the United States, reflecting increases in the values insured on existing policies, higher renewal rates, strong retention of existing business, and new business. Growth in homeowners premiums in the second quarter reflected a modest benefit from a modification in terms related to a ceded reinsurance contract that resulted in a reinsurance return premium. Net premiums written outside the United States for our homeowners business decreased in the first six months and second quarter of 2015 compared with the same periods of 2014, due to the negative effect of foreign currency translation.

Net premiums written for our other personal business, which includes accident and health, excess liability and yacht coverages, increased in the first six months of 2015 compared with the same period of 2014, driven by significant growth in the United States. Premiums for our other personal business written outside the United States decreased significantly in the first six months of 2015 compared with the same period of 2014, due to the negative effect of foreign currency translation. Net premiums written for our other personal business were flat in the second quarter of 2015 compared with the same period of 2014, as a significant increase in net premiums written inside the United States was offset by a significant decrease in net premiums written outside the United States. The decrease in net premiums written outside the United States in the second quarter of 2015 was largely due to the negative effect of foreign currency translation. Premiums for our accident and health business, about half of which was written outside the United States in the first six months of 2015, increased slightly in the first six months of 2015 and decreased modestly in the second quarter compared with the same periods of 2014. In both periods of 2015, significant growth occurred in the United States. Accident and health premiums written outside the United States decreased in the first six months and second quarter of 2015, more so in the second quarter, due in large part to the negative effect of foreign currency translation. Premiums for our excess liability business, most of which is written in the United States, increased in the first six months and second quarter of 2015 compared with the same periods of 2014.

Our personal insurance segment produced similarly profitable underwriting results in the first six months of 2015 and 2014. Results for our personal insurance segment were also profitable in the second quarter of both years, but more so in 2015. The combined loss and expense ratios for the classes of business within the personal insurance segment were as follows:

Periods Ended June 30
Six Months Second Quarter
2015 2014 2015 2014

Automobile

98.0 98.5 103.1 95.6

Other

91.5 92.8 90.7 93.1

Total personal

97.1 97.2 89.5 92.7

The combined loss and expense ratio for our personal insurance segment was similar in the first six months of 2015 and 2014, reflecting slightly improved results in our personal automobile and other personal businesses, mostly offset by slightly worse results in our homeowners business. The 3.2 percentage point decrease in the combined loss and expense ratio for our personal insurance segment in the second quarter of 2015 compared with the same period of 2014 was driven mainly by improved results for our homeowners business, partially offset by worse results in our personal automobile business. The impact of catastrophes accounted for 13.1 percentage points of the combined ratio for our personal insurance segment in the first six months of 2015 and 7.8 percentage points in the second quarter compared with 9.3 and 7.5 percentage points, respectively, in the same periods of 2014.

Personal automobile results improved slightly in the first six months of 2015 and 2014, as modestly better results inside the United States in the 2015 period were substantially offset by modestly worse results outside the United States. Our personal automobile business produced profitable results in the United States in the first six months of both years, but more so in 2015. Personal automobile results outside the United States were unprofitable in the first six months of both years, but more so in 2015. Personal automobile results were unprofitable in the second quarter of 2015 compared with profitable results in the same period of 2014. The 7.5 percentage point increase in the combined ratio in the second quarter of 2015 compared with the same period of 2014 reflected a higher impact of catastrophes and a higher current accident year loss ratio excluding catastrophes. Additionally, results in the second quarter of 2014 benefited from favorable prior year loss development. Results in the United States were slightly unprofitable in the second quarter of 2015 compared with profitable results in the same period of 2014. Results outside the United States were unprofitable in the second quarter of both years, but more so in 2015.

Homeowners results were profitable in the first six months of 2015 and 2014, but slightly more so in 2014. The 0.6 of a percentage point increase in the combined ratio in the first six months of 2015 compared with the same period of 2014 was due to a higher impact of catastrophes substantially offset by a lower current accident year loss ratio excluding catastrophes. Homeowners results were profitable in the second quarter of both years, but more so in 2015. The 6.3 percentage point decrease in the combined ratio in the second quarter of 2015 compared with the same period of 2014 was due primarily to a lower current accident year loss ratio excluding catastrophes. The lower current accident year loss ratio excluding catastrophes in the 2015 periods reflected a decrease in fire losses compared with the same periods of 2014. The impact of catastrophes accounted for 20.7 percentage points of the combined ratio for this class in the first six months of 2015 and 11.8 percentage points in the second quarter compared with 15.0 and 12.1 percentage points, respectively, in the same periods of 2014.

Other personal results were profitable in the first six months and second quarter of 2015 and 2014, but more so in the 2015 periods, due primarily to more profitable results in the excess liability component of this business. Results for the excess liability component of this business were highly profitable in the first six months and second quarter of 2015 compared to profitable results in the same periods of 2014. Excess liability results benefited from favorable prior year loss development in the first six months and second quarter of both years, but more so in the 2015 periods. The accident and health component of this business produced slightly profitable results in the first six months and second quarter of 2015 and 2014. In the first six months of both years, results for our accident and health business were profitable in the United States and modestly unprofitable outside the United States. Our accident and health business in the United States also produced profitable results in the second quarter of both years. Outside the United States, this business produced near breakeven results in the second quarter of 2015 compared with slightly unprofitable results in the same period of 2014. Our yacht business produced profitable results in the first six months of 2015 and near breakeven results in the second quarter compared with highly profitable results in the same periods of 2014.

Commercial Insurance

Net premiums written in our commercial insurance segment, which represented 45% of our total net premiums written in the first six months of 2015, increased by 3% in the first six months of 2015 and 5% in the second quarter compared with the same periods of 2014. Net premiums written for the classes of business within the commercial insurance segment were as follows:

Growth in net premiums written in our commercial insurance segment in the first six months and second quarter of 2015 compared with the same periods of 2014 was driven by growth in the United States. Net premiums written outside the United States decreased modestly in the first six months and second quarter of 2015, due to the negative effect of foreign currency translation. Excluding the effect of foreign currency translation, net premiums written outside the United States increased in both periods of 2015. Overall premium growth in our commercial insurance segment excluding the effect of foreign currency translation was 6% in the first six months of 2015 and 7% in the second quarter. Such growth reflected high retention, new business and higher rates upon renewal. The most significant growth in our commercial insurance segment in the first six months and second quarter of 2015 occurred in the workers' compensation class, which is primarily written in the United States, reflecting high retention, higher renewal exposure and new business. In the first six months and second quarter of 2015, growth in net premiums written for the other classes within our commercial insurance segment was less significant, due in part to the negative effect of foreign currency translation on net premiums written outside the United States. Average renewal rates in our commercial insurance segment in the United States were up slightly in the first six months and second quarter of 2015 compared with expiring rates, but the level of increase was lower than in recent years. Average renewal rates outside the United States were flat in the first six months of 2015 and up slightly in the second quarter compared to expiring rates. Retention levels of our existing policyholders were strong in the first six months and second quarter of both years. Retention levels in the United States were modestly higher in the first six months and second quarter of 2015 compared with the same periods of 2014. Retention levels outside the United States were up slightly in the first six months of 2015 and up modestly in the second quarter compared with the same periods of 2014. The average renewal exposure change was flat inside the United States in the first six months and second quarter of 2015. The average renewal exposure change was flat outside the United States in the first six months of 2015, but up slightly in the second quarter. The amount of new business, both inside and outside the United States, was higher in the first six months of 2015 compared with the same period of 2014, as a result of more opportunities to write business at appropriate rates. The amount of new business was flat inside the United States and modestly lower outside the United States in the second quarter of 2015 compared with the same period of 2014.

Our commercial insurance segment produced profitable underwriting results in the first six months and second quarter of 2015 and 2014, but more so in the 2015 periods. The combined loss and expense ratios for the classes of business within the commercial insurance segment were as follows:

The 1.9 percentage point decrease in the combined loss and expense ratio for our commercial insurance segment in the first six months of 2015 compared with the same period of 2014 was due to a lower current accident year loss ratio excluding catastrophes and a lower impact of catastrophes, offset in part by a lower amount of favorable prior year loss development. The 6.1 percentage point decrease in the combined loss and expense ratio for our commercial insurance segment in the second quarter of 2015 compared with the same period of 2014 was due to a lower current accident year loss ratio excluding catastrophes and, to a lesser extent, a higher amount of favorable prior year loss development and a lower impact of catastrophes. The impact of catastrophes accounted for 3.9 percentage points of the combined ratio for our commercial insurance segment in the first six months of 2015 and 4.4 percentage points in the second quarter compared with 5.5 and 4.9 percentage points, respectively, in the same periods of 2014. Results for our commercial insurance segment in the first six months and second quarter of 2015 and 2014 benefited from favorable prior year loss development and our disciplined risk selection in recent years.

Multiple peril results were profitable in the first six months of 2015 and 2014, but more so in 2014. Multiple peril results were similarly profitable in the second quarter of both years. The 2.7 percentage point increase in the combined ratio in the first six months of 2015 compared with the same period of 2014 was due to worse results for the property component of this business, offset in part by better results in the liability component. Results for the property component of this business were slightly unprofitable in the first six months of 2015 compared with profitable results in the same period of 2014. Results for this component were profitable in the second quarter of both years, but slightly more so in 2014. Results for the liability component of this business were highly profitable in the first six months of 2015 compared with profitable results in the same period of 2014. Results for this component were highly profitable in the second quarter of both years. The impact of catastrophes accounted for 8.1 percentage points of the combined ratio for the multiple peril class in the first six months of 2015 and 6.5 percentage points in the second quarter compared with 7.2 and 5.0 percentage points, respectively, in the same periods of 2014.

Casualty results were profitable in the first six months and second quarter of 2015 and 2014. The 0.8 of a percentage point decrease in the combined ratio in the first six months of 2015 compared with the same period of 2014 was due mainly to more profitable results in the primary liability component of this business. The 5.7 percentage point decrease in the combined ratio in the second quarter of 2015 compared with the same period of 2014 was driven by more profitable results in the primary liability and excess liability components of this business. Results for the primary liability component were profitable in the first six months and second quarter of 2015 and 2014, but more so in the 2015 periods. Results for the excess liability component were highly profitable in the first six months and second quarter of 2015 and 2014. Excess liability results in all periods benefited from substantial favorable prior year loss development driven mainly by lower than expected claim severity. Results for the automobile component were slightly unprofitable in the first six months of 2015 and 2014. Results for this component were also slightly unprofitable in the second quarter of 2015 compared with unprofitable results in the same period of 2014. Casualty results were adversely affected by incurred losses related to asbestos and toxic waste claims in the first six months and second quarter of 2015 and 2014. Our analysis of these exposures resulted in an increase in the estimate of our ultimate liabilities. Such losses represented 2.3 percentage points of the combined ratio for our casualty business in the first six months of 2015 and 2.7 percentage points in the second quarter compared with 1.4 and 2.5 percentage points, respectively, in the same periods of 2014.

Workers' compensation results were profitable in the first six months and second quarter of 2015 and 2014, but more so in the 2014 periods. The 3.2 percentage point increase in the combined ratio in the first six months of 2015 compared with the same period of 2014 was due to a lower amount of favorable prior year loss development and, to a lesser extent, a slightly higher current accident year loss ratio. The 6.3 percentage point increase in the combined ratio in the second quarter of 2015 compared with the same period of 2014 was due to a slight amount of unfavorable prior year loss development in 2015 compared with favorable development in the same period of 2014. The increase in the combined ratio was also due to a slightly higher current accident year loss ratio in the second quarter of 2015 compared with the same period of 2014. Results in all periods reflected our disciplined risk selection during the past several years.

Property and marine results were profitable in the first six months of 2015 compared with near breakeven results in the same period of 2014. Results were profitable in the second quarter of 2015 compared with unprofitable results in the same period of 2014. The 10.7 percentage point decrease in the combined ratio in the first six months of 2015 compared with the same period of 2014 was due to a lower impact of catastrophes and a lower current accident year loss ratio excluding catastrophes. The 21.3 percentage point decrease in the combined ratio in the second quarter of 2015 compared to the same period of 2014 was due in part to a lower current accident year loss ratio excluding catastrophes. Additionally, results in the second quarter of 2015 reflected favorable prior year loss development whereas results in the same period of 2014 reflected unfavorable prior year loss development. The lower combined ratio in the second quarter of 2015 also reflected a modestly lower impact of catastrophes. The impact of catastrophes accounted for 7.9 percentage points of the combined ratio in the first six months of 2015 and 11.2 percentage points in the second quarter compared with 13.9 and 13.1 percentage points, respectively, in the same periods of 2014.

Specialty Insurance

Net premiums written in our specialty insurance segment, which represented 20% of our total net premiums written in the first six months of 2015, were flat in the first six months and second quarter of 2015 compared with the same periods of 2014. Net premiums written for the classes of business within the specialty insurance segment were as follows:

The lack of growth in net premiums written in our specialty insurance segment in the first six months and second quarter of 2015 compared with the same periods of 2014 reflected the negative effect of foreign currency translation. Premium growth excluding the effect of foreign currency translation was 3% in the first six months and second quarter of 2015.

The decrease in net premiums written for our professional liability business in the first six months of 2015 and the insignificant growth in the second quarter were driven by a significant decline in net premiums written outside the United States in both periods compared with the same periods of 2014, due to the negative effect of foreign currency translation. Net premiums written in the United States were modestly higher in the first six months and second quarter of 2015 compared with the same periods of 2014. Overall premium growth in our professional liability business continued to reflect our focus on profitability in the pricing of renewal policies and new business, in what remains a competitive marketplace. Retention levels for this business remained strong and were slightly higher in the first six months and second quarter of 2015 compared with those in the same periods of 2014, both inside and outside the United States. New business increased in the United States in the first six months and second quarter of 2015 compared with the same periods of 2014, but decreased outside the United States. The new business volume in the first six months and second quarter of 2015, particularly in the United States, reflected opportunities to write suitably priced business in select classes due to the positive pricing trends in the market over the last few years. Average renewal rates in the United States for our professional liability business were up modestly in the first six months and second quarter of 2015 compared with expiring rates, with increases occurring in most classes of this business. Average renewal rates outside the United States were flat in the first six months of 2015 and up slightly in the second quarter compared with expiring rates. On average, the amounts of insured exposures upon renewal were up slightly in the United States and close to flat outside the United States in the first six months and second quarter of 2015.

The increase in net premiums written for our surety business in the first six months of 2015 compared with the same period of 2014 was driven by an increase in premiums written outside the United States. Net premiums written in the United States for our surety business increased slightly in the first six months of 2015. In the second quarter of 2015, net premiums written for our surety business were flat, as a modest increase inside the United States was offset by a modest decrease outside the United States. Growth in net premiums written outside the United States in both periods of 2015 reflected the negative effect of foreign currency translation. Premiums written in our surety business depend significantly on the extent to which our existing customers are awarded contracts to perform services. As a result, premium growth in our surety business can often vary from period to period.

Our specialty insurance business produced profitable underwriting results in the first six months and second quarter of 2015 and 2014, but more so in the 2015 periods. The combined loss and expense ratios for the classes of business within the specialty insurance segment were as follows:

Periods Ended June 30

2015 2014 2015 2014

Professional liability

82.9 83.9 80.7 83.2

Surety

The 5.2 percentage point decrease in the combined loss and expense ratio for our specialty insurance segment in the first six months of 2015 compared with the same period of 2014 was driven primarily by improved results for our surety business. The 3.5 percentage point decrease in the combined loss and expense ratio for our specialty insurance segment in the second quarter of 2015 was driven by improved results in both our professional liability and surety businesses.

Professional liability results were profitable in the first six months and second quarter of 2015 and 2014, but more so in the 2015 periods. The 1.0 percentage point decrease in the combined ratio for this business in the first six months of 2015 compared with the same period of 2014 was due primarily to improved current accident year results, including a lower expense ratio, offset in part by a slightly lower amount of favorable prior year loss development. The 2.5 percentage point decrease in the combined ratio for this business in the second quarter of 2015 compared with the same period of 2014 was due to improved current accident year results, including a lower expense ratio.

Results for the directors and officers liability class were highly profitable in the first six months and second quarter of 2015 and 2014, but more so in the 2014 periods. Results for this class reflected favorable prior year loss development in all periods, but more so in the 2014 periods. Results for the fiduciary liability class were also highly profitable in the first six months and second quarter of 2015 and 2014, with results in all periods reflecting favorable prior year loss development. Results for the fidelity class were highly profitable in the first six months of both years, but more so in 2015. Results for this class were also highly profitable in the second quarter of 2015 compared with profitable results in the same period of 2014. Results for this class reflected slightly favorable prior year loss development in the 2015 periods compared with unfavorable prior year loss development in the 2014 periods. Results for the employment practices liability class were modestly unprofitable in the first six months and second quarter of 2015 and 2014. Results for the errors and omissions liability class were profitable in the first six months and second quarter of 2015 compared with unprofitable results in the same periods of 2014. Results for this class reflected favorable prior year loss development in the first six months and second quarter of 2015 compared with unfavorable prior year loss development in the same periods of 2014.

Surety results were profitable in the first six months and second quarter of 2015 and 2014, but more so in the 2015 periods. The combined ratio was 38.2 and 11.5 percentage points lower in the first six months and second quarter of 2015, respectively, compared with the same periods of 2014. The significantly higher combined ratio in the first six months of 2014 was due to one large loss in the first quarter outside the United States. Our surety business tends to be characterized by losses that are infrequent but have the potential to be highly severe.

Reinsurance Assumed

Net premiums written in our runoff reinsurance assumed business were not significant in the first six months and second quarter of 2015 or 2014. Results for this business were profitable in the first six months and second quarter of 2015 compared with breakeven results in the same periods of 2014. Results in the 2015 periods benefited from favorable prior year loss development.

Catastrophe Risk Management

Our property and casualty insurance subsidiaries have exposure to losses caused by natural perils such as hurricanes and other windstorms, earthquakes, severe winter weather and brush fires as well as from man-made catastrophic events such as terrorism. The frequency and severity of catastrophes are inherently unpredictable.

The extent of losses from a catastrophe is a function of both the total amount of insured exposure in an area affected by the event and the severity of the event. We regularly assess our concentrations of risk in catastrophe exposed areas globally and have strategies and underwriting standards to manage these exposures through individual risk selection, subject to regulatory constraints, and through the purchase of catastrophe reinsurance coverage. We use catastrophe modeling and a risk concentration management tool to monitor and control our accumulations of potential losses in catastrophe exposed areas in the United States, such as California and the gulf and east coasts, as well as in catastrophe exposed areas in other countries. The information provided by the catastrophe modeling and the risk concentration management tool has resulted in our non-renewing or reducing our exposure on some accounts and refraining from writing others.

Catastrophe modeling generally relies on multiple inputs based on experience, science, engineering and history, and the selection of those inputs requires a significant amount of judgment. Also, the modeling results may fail to account for risks that are outside the range of normal probability or are otherwise unforeseen. Because of this, actual results may differ materially from those derived from our modeling exercises.

We also continue to assess how changes in catastrophe risk, including the potential impact of global climate change, may affect our ability to manage our exposure under the insurance policies we issue, as well as how laws and regulations intended to combat climate change may affect us.

Despite our efforts to manage our catastrophe exposure, the occurrence of one or more severe catastrophic events could have a material effect on the Corporation's results of operations, financial condition or liquidity.

Loss Reserves

Unpaid losses and loss expenses, also referred to as loss reserves, are the largest liability of our property and casualty insurance subsidiaries.

Our loss reserves include case estimates for claims that have been reported and estimates for claims that have been incurred but not reported at the balance sheet date as well as estimates of the expenses associated with processing and settling all reported and unreported claims, less estimates of anticipated salvage and subrogation recoveries. Estimates are based upon past loss experience modified for current trends as well as prevailing economic, legal and social conditions. Our loss reserves are not discounted to present value.

We regularly review our loss reserves using a variety of actuarial techniques. We update the reserve estimates as historical loss experience develops, additional claims are reported and/or settled and new information becomes available. Any changes in estimates are reflected in operating results in the period in which the estimates are changed.

Incurred but not reported (IBNR) reserve estimates are generally calculated by first projecting the ultimate cost of all claims that have occurred and then subtracting reported losses and loss expenses. Reported losses include cumulative paid losses and loss expenses plus case reserves. The IBNR reserve includes a provision for claims that have occurred but have not yet been reported to us, some of which are not yet known to the insured, as well as a provision for future development on reported claims. A relatively large proportion of our net loss reserves, particularly for long tail liability classes, are reserves for IBNR losses. In fact, about 75% of our aggregate net loss reserves at June 30, 2015 were for IBNR losses.

Loss reserves, net of reinsurance recoverable, decreased by $83 million during the first six months of 2015. The decrease in loss reserves during the first six months of 2015 included a decrease of $301 million related to the effect of foreign currency translation, due to a stronger U.S. dollar relative to the currencies in which our loss reserves were held at June 30, 2015 compared with December 31, 2014. The decrease in loss reserves also reflected an increase of $136 million related to catastrophe losses. Loss reserves related to our insurance business decreased by $64 million and loss reserves related to our runoff reinsurance assumed business decreased by $19 million.

The increase in gross loss reserves in the homeowners class during the first six months of 2015 was driven by catastrophe losses. The decrease in gross loss reserves in the casualty classes was due to the effect of foreign currency translation. The increase in gross loss reserves in the workers' compensation class was driven mainly by increased exposures. The decrease in gross loss reserves in the professional liability classes reflected the effect of foreign currency translation, as well as payment activity and favorable prior year loss development.

In establishing the loss reserves of our property and casualty insurance subsidiaries, we consider facts currently known and the present state of the law and coverage litigation. Based on all information currently available, we believe that the aggregate net loss reserves at June 30, 2015 were adequate to cover claims for losses that had occurred as of that date, including both those known to us and those yet to be reported. However, as discussed in Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2014, there are significant uncertainties inherent in the loss reserving process. It is therefore possible that management's estimate of the ultimate liability for losses that had occurred as of June 30, 2015 may change, which could have a material effect on the Corporation's results of operations and financial condition.

Changes in loss reserve estimates are unavoidable because such estimates are subject to the outcome of future events. Loss trends vary and time is required for changes in trends to be recognized and confirmed. Reserve changes that increase previous estimates of ultimate cost are referred to as unfavorable or adverse development or reserve strengthening. Reserve changes that decrease previous estimates of ultimate cost are referred to as favorable development or reserve releases.

We estimate that we experienced overall favorable development of about $295 million in the first six months of 2015 and $185 million in the second quarter compared with favorable development of about $325 million and $165 million, respectively, in the same periods of 2014, on net loss reserves established as of the respective prior year end.

The favorable development in the first six months of 2015 was primarily in the professional liability classes due to favorable loss experience related mainly to accident years 2013 and prior, and in the commercial liability classes due to favorable loss experience related mainly to accident years 2012 and prior. The favorable development in the first six months of 2014 was primarily in the professional liability classes due to favorable loss experience related mainly to accident years 2010 and prior, and in the commercial liability classes due to favorable loss experience related mainly to accident years 2012 and prior.

Investment Results

Our ability to grow our property and casualty investment income is a function of several variables, including investable cash flows, available reinvestment rates and foreign currency to U.S. dollar exchange rates. The property and casualty subsidiaries' investable cash flows are impacted by many factors, including operating activities, the payment of dividends to Chubb and the timing of maturities, calls and redemptions of fixed maturities. Economic conditions and national monetary policies both inside and outside the United States have resulted in a low interest rate environment in recent years that is expected to continue to adversely affect our ability to increase our investment income.

Property and casualty investment income before taxes decreased by 6% in the first six months of 2015 and 5% in the second quarter compared with the same periods in 2014. The decrease was due primarily to a decline in the average yield of our property and casualty subsidiaries' investment portfolio and, to a lesser extent, the impact of foreign currency translation, partially offset by the impact of an increase in our average invested assets. The decrease in the average yield on the investment portfolio primarily resulted from lower reinvestment yields on securities that we purchased to replace fixed maturities that matured, were redeemed by the issuer or were sold since the second quarter of 2014. While the property and casualty subsidiaries generated substantial operating cash flows in the last six months of 2014 and the first six months of 2015, average invested assets were impacted by substantial dividend distributions made by the property and casualty subsidiaries to Chubb during 2014 and the first quarter of 2015. As a result of the dividend distributions, our property and casualty subsidiaries held only a slightly higher amount of average invested assets in the first six months of 2015 and in the second quarter compared with the same periods in 2014.

The effective tax rate on our investment income was 17.5% in the first six months of 2015 compared with 18.5% in the same period of 2014. The effective tax rate on our investment income is lower than the U.S. statutory tax rate since a portion of our investment income is tax exempt interest income. The effective tax rate fluctuates as the proportion of tax exempt investment income relative to total investment income changes from period to period.

On an after-tax basis, property and casualty investment income decreased by 5% in the first six months and 4% in the second quarter of 2015 compared with the same periods in 2014. The after-tax annualized yield on our property and casualty subsidiaries' investment portfolio was 2.66% and 2.80% in the first six months of 2015 and 2014, respectively.

Other Income and Charges

Other income and charges, which includes miscellaneous income and expenses of the property and casualty subsidiaries, was not significant in the first six months of 2015 and 2014.

Table of Contents

Page 49

Corporate and Other

Corporate and other comprises investment income earned on corporate invested assets, interest expense and other expenses not allocated to our operating subsidiaries and the results of our non-insurance subsidiaries.

Corporate and other produced a loss before taxes of $143 million in the first six months of 2015 compared with a loss of $119 million for the same period of 2014. The higher loss for the first six months of 2015 compared with the same period of 2014 was due primarily to expenses of $20 million related to the Merger incurred in the second quarter of 2015. The Corporation expects to continue to incur expenses relating to the Merger in future periods, which may have a material effect on the results of operations of the Corporation for the relevant period.

The net realized gains and losses of other invested assets primarily include the aggregate of realized gain distributions to us from the private equity limited partnerships in which we have an interest and changes in our equity in the net assets of those partnerships based on valuations provided to us by the manager of each partnership. Due to the timing of our receipt of valuation data from the investment managers, the value of these investments and any related realized gains and losses are generally reported on a one quarter lag.

Table of Contents

Page 50

The net realized gains of the limited partnerships reported in the first six months of 2015 primarily reflected the positive performance of the U.S. equity markets in the first quarter of 2015 and the fourth quarter of 2014. The net realized gains of the limited partnerships reported in the first six months of 2014 primarily reflected the positive performance of the global equity and high yield investment markets in the first quarter of 2014 and the fourth quarter of 2013.

We regularly review invested assets that have a fair value less than cost to determine if an other-than-temporary decline in value has occurred. We have a monitoring process overseen by a committee of investment and accounting professionals that is responsible for identifying those securities to be specifically evaluated for a potential other-than-temporary impairment.

The determination of whether a decline in value of any investment is temporary or other than temporary requires the judgment of management. The assessment of other-than-temporary impairment of fixed maturities and equity securities is based on both quantitative criteria and qualitative information. A number of factors are considered including, but not limited to, the length of time and the extent to which the fair value has been less than the cost, the financial condition and near term prospects of the issuer, whether the issuer is current on contractually obligated interest and principal payments, general market conditions and industry or sector specific factors. The decision to recognize a decline in the value of a security carried at fair value as other than temporary rather than temporary has no impact on shareholders' equity.

In determining whether fixed maturities are other than temporarily impaired, we are required to recognize an other-than-temporary impairment loss when we conclude that we have the intent to sell or it is more likely than not that we will be required to sell an impaired fixed maturity before the security recovers to its amortized cost value or it is likely we will not recover the entire amortized cost value of an impaired security. If we have the intent to sell or it is more likely than not that we will be required to sell an impaired fixed maturity before the security recovers to its amortized cost value, the security is written down to fair value and the entire amount of the writedown is included in net income as a realized investment loss. For all other impaired fixed maturities, when the impairment is determined to be other than temporary, the impairment loss is separated into the amount representing the credit loss and the amount representing the loss related to all other factors. The amount of the impairment loss that represents the credit loss is included in net income as a realized investment loss and the amount of the impairment loss that relates to all other factors is included in other comprehensive income.

In determining whether equity securities are other than temporarily impaired, we consider our intent and ability to hold a security for a period of time sufficient to allow us to recover our cost. If a decline in the fair value of an equity security is deemed to be other than temporary, the security is written down to fair value and the amount of the writedown is included in net income as a realized investment loss.

Capital resources provide protection for policyholders, furnish the financial strength to support the business of underwriting insurance risks and facilitate continued business growth. At June 30, 2015, the Corporation had shareholders' equity of $15.9 billion and total debt of $3.3 billion.

Management regularly monitors the Corporation's capital resources. In connection with our long term capital strategy, from time to time Chubb may contribute capital to its property and casualty subsidiaries. In addition, in order to satisfy capital needs as a result of any rating agency capital adequacy or other future rating issues, or in the event we were to need additional capital to make strategic investments in light of market opportunities, we may take a variety of actions, which could include the issuance of additional debt and/or equity securities. We believe that our strong financial position and current debt level provide us with the flexibility and capacity to obtain funds externally through debt or equity financings on both a short term and long term basis. Pursuant to the Merger Agreement, the Corporation, without the prior written consent of ACE, cannot take certain actions until the effective time of the Merger or termination of the Merger Agreement, including incurring any additional indebtedness, issuing equity, selling any material properties or assets, acquiring assets or making, or committing to make, capital expenditures, in each case except as permitted pursuant to the Merger Agreement.

In January 2014, the Board of Directors (the Board) authorized the repurchase of up to $1.5 billion of Chubb's common stock. Repurchases under this authorization were completed in January 2015. On January 29, 2015, the Board authorized the repurchase of up to $1.3 billion of Chubb's common stock. During the first six months of 2015, under these two authorizations we repurchased 6,046,623 shares of Chubb's common stock in open market transactions at a cost of $604 million. As of June 30, 2015, $749 million remained under the January 2015 authorization. During the second quarter of 2015, Chubb suspended repurchases of its common stock in connection with its agreeing to be acquired by ACE, which was announced on July 1, 2015.

Ratings

Chubb and its property and casualty insurance subsidiaries are rated by major rating agencies. These ratings reflect the rating agency's opinion of our financial strength, operating performance, strategic position and ability to meet our obligations to policyholders.

Credit ratings assess a company's ability to make timely payments of interest and principal on its debt. Financial strength ratings assess an insurer's ability to meet its financial obligations to policyholders.

Page 52

Chubb's issuer credit ratings and its property and casualty subsidiaries' financial strength ratings were provided in Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2014. On April 16, 2015, A.M. Best raised the issuer credit rating for Chubb's senior unsecured debt to "aa" from "aa-" and for junior subordinated capital securities to "a+" from "a."

As of August 5, 2015, following the announcement of the pending Merger, the issuer credit ratings of Chubb from the four principal rating agencies were left unchanged, although three of the four rating agencies revised their outlook on the rating. On July 1, 2015, Fitch Ratings placed the rating on "Rating Watch Negative" and Standard & Poor's placed the rating on "CreditWatch with negative implications." On July 2, 2015, A.M. Best placed the rating "under review with negative implications." Additionally, on July 2, 2015, Moody's affirmed the rating with a stable outlook. Concurrent with these actions, Chubb's property and casualty subsidiaries' financial strength ratings were affirmed by all four of the principal rating agencies, with two revising their outlook. On July 1, 2015, Standard & Poor's revised the outlook on the rating to "negative" and, on July 2, 2015, A.M. Best placed the rating "under review with negative implications." The rating agencies may take various actions, positive or negative, and their actions may not be known until the Merger closes.

Ratings are an important factor in establishing our competitive position in the insurance markets. There can be no assurance that our ratings will continue for any given period of time or that they will not be changed.

If our credit ratings were downgraded, we might incur higher borrowing costs and might have more limited means to access capital. A downgrade in our financial strength ratings could adversely affect the competitive position of our insurance operations, including a possible reduction in demand for our products in certain markets.

Liquidity

Liquidity is a measure of a company's ability to generate sufficient cash flows to meet the short and long term cash requirements of its business operations.

The Corporation's liquidity requirements in the past have generally been met by funds from operations and we expect that funds from operations will continue to be sufficient to meet such requirements in the future. Liquidity requirements could also be met by funds received upon the maturity or sale of marketable securities in our investment portfolio. Chubb also has the ability to borrow under its $500 million credit facility and we believe we could issue debt or equity securities, subject, in each case, to obtaining ACE's prior written consent as required under the terms of the Merger Agreement.

Our property and casualty operations provide liquidity in that insurance premiums are generally received months or even years before losses are paid under the policies purchased by such premiums. Cash receipts from operations, consisting of insurance premiums and investment income, provide funds to pay losses, operating expenses and dividends to Chubb. Cash receipts in excess of required cash outflows can be used to build the investment portfolio with the expectation of generating additional investment income in the future.

Table of Contents

Page 53

Our property and casualty subsidiaries maintain substantial investments in highly liquid, short term marketable securities. Accordingly, we do not anticipate selling long term fixed maturities to meet any liquidity needs.

Chubb's liquidity requirements primarily include the payment of dividends to shareholders and interest and principal on debt obligations. The declaration and payment of dividends to Chubb's shareholders is at the discretion of Chubb's Board and depends upon many factors, including our operating results, financial condition, capital requirements and any regulatory constraints.

As a holding company, Chubb's ability to continue to pay dividends to shareholders and to satisfy its debt obligations relies on the availability of liquid assets, which is dependent in large part on the dividend paying ability of its property and casualty subsidiaries. The timing and amount of dividends paid by the property and casualty subsidiaries to Chubb may vary from year to year. In the United States, our property and casualty subsidiaries are subject to laws and regulations in the jurisdictions in which they operate that restrict the amount and timing of dividends they may pay within twelve consecutive months without the prior approval of regulatory authorities. The restrictions are generally based on net income and on certain levels of policyholders' surplus as determined in accordance with statutory accounting principles. Dividends in excess of such thresholds are considered "extraordinary" and require prior regulatory approval.

During the first six months of 2015, the property and casualty subsidiaries paid dividends of $925 million to Chubb. As of June 30, 2015, the maximum aggregate dividend distribution that may be made by the subsidiaries to Chubb during the remainder of 2015 without prior regulatory approval was approximately $930 million.

Pursuant to the Merger Agreement, Chubb has agreed to use its reasonable best efforts to have available $3 billion in cash and cash equivalents prior to the effective time of the Merger. It is expected that, immediately after the effective time of the Merger, Chubb will pay to its shareholder after the Merger a dividend of $3 billion that will be used by ACE in connection with the funding of a portion of the cash consideration in the Merger. It currently is expected that, depending on when the effective time occurs and subject to regulatory approval, a portion of the $3 billion in cash and cash equivalents that may be held by Chubb prior to the effective time of the Merger will be from an extraordinary dividend paid by the property and casualty subsidiaries to Chubb prior to the effective time of the Merger, with the balance comprising cash and cash equivalents otherwise held by Chubb at that time.

The Corporation's strong underwriting and investment results generated substantial positive operating cash flows of $1,082 million and $778 million in the first six months of 2015 and 2014, respectively. The cash provided by operating activities increased $304 million in the first six months of 2015 compared with the same period of 2014 primarily as a result of lower loss payments and, to a lesser extent, higher premium collections.

Invested Assets

The main objectives in managing our investment portfolios are to maximize after-tax investment income and total investment return while managing credit risk and interest rate risk in order to ensure that funds will be available to meet our insurance and other obligations. Investment strategies are developed based on many factors including underwriting results and our resulting tax position, regulatory requirements, fluctuations in interest rates and consideration of other market risks. Investment decisions are centrally managed by investment professionals based on guidelines established by management and approved by the boards of directors of Chubb and its respective operating companies.

Our investment portfolio primarily comprises high quality bonds, principally tax exempt securities, corporate bonds, U.S. Treasury securities and mortgage-backed securities, as well as foreign government and corporate bonds that support our operations outside the United States. The portfolio also includes equity securities, primarily publicly traded common stocks, and other invested assets, primarily private equity limited partnerships, all of which are held with the primary objective of capital appreciation.

Our objective is to achieve an appropriate mix of taxable and tax exempt securities in our portfolio to balance both investment and tax strategies. At June 30, 2015, 66% of our U.S. fixed maturity portfolio was invested in tax exempt securities. At June 30, 2015, about 75% of our tax exempt securities were rated Aa or better, with about 20% rated Aaa. The average rating of our tax exempt securities was Aa. While about 10% of our tax exempt securities were insured, the effect of insurance on the average credit rating of these securities was insignificant. The insured tax exempt securities in our portfolio have been selected based on the quality of the underlying credit and not the value of the credit insurance enhancement.

At June 30, 2015, 7% of our taxable fixed maturity portfolio was invested in U.S. government and government agency and authority obligations other than mortgage-backed securities and had an average rating of Aa. About 70% of the U.S. government and government agency and authority obligations other than mortgage-backed securities were U.S. Treasury securities with an average rating of Aaa and the remainder were taxable bonds issued by states, municipalities and political subdivisions within the United States with an average rating of Aa.

At June 30, 2015, 51% of our taxable fixed maturity portfolio consisted of corporate bonds that were issued by a diverse group of U.S. and foreign issuers and had an average rating of A. About 60% of our corporate bonds were issued by U.S. companies and about 40% were issued by foreign companies. At June 30, 2015, about 3% of our foreign corporate bonds were below investment grade.

At June 30, 2015, 35% of our taxable fixed maturity portfolio was invested in foreign government and government agency obligations, which had an average rating of Aa. The foreign government and government agency obligations consisted of high quality securities, primarily issued or guaranteed by national governments and, to a lesser extent, government agencies, regional governments and supranational organizations. The five largest sovereign issuers within our portfolio were Canada, the United Kingdom, Germany, Australia and Brazil, which collectively accounted for about 75% of our total foreign government and government agency obligations. Another 7% of our total foreign government and government agency obligations were issued by supranational organizations. At June 30, 2015, none of our foreign government and government agency obligations were below investment grade. We did not hold any foreign government or government agency obligations that have third party guarantees.

Table of Contents

Page 55

At June 30, 2015, 7% of our taxable fixed maturity portfolio was invested in mortgage-backed securities. About 95% of the mortgage-backed securities were rated Aaa. About half of the remaining 5% were below investment grade. Of the Aaa rated securities, 89% were call protected, commercial mortgage-backed securities (CMBS). All of our CMBS were senior securities with the highest level of credit support. The other 11% of the Aaa rated securities were residential mortgage-backed securities, consisting of government agency pass-through securities guaranteed by a government agency or a government sponsored enterprise and collateralized mortgage obligations backed by single family home mortgages.

The net unrealized appreciation before tax of our fixed maturities and equity securities carried at fair value was $2.3 billion at June 30, 2015 compared with net unrealized appreciation before tax of $2.7 billion at December 31, 2014. Such unrealized appreciation is reflected in accumulated other comprehensive income, net of applicable deferred income taxes.

Fair Values of Financial Instruments

Fair values of financial instruments are determined by management using valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. Fair values are generally measured using quoted prices in active markets for identical assets or liabilities or other inputs, such as quoted prices for similar assets or liabilities, that are observable, either directly or indirectly. In those instances where observable inputs are not available, fair values are measured using unobservable inputs for the asset or liability. Unobservable inputs reflect our own assumptions about the assumptions that market participants would use in pricing the asset or liability and are developed based on the best information available in the circumstances. Fair value estimates derived from unobservable inputs are affected by the assumptions used, including the discount rates and the estimated amounts and timing of future cash flows. The derived fair value estimates cannot be substantiated by comparison to independent markets and are not necessarily indicative of the amounts that would be realized in a current market exchange.

The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels as follows:

Level 1 – Unadjusted quoted prices in active markets for identical financial instruments.

Level 2 – Other inputs that are observable for the financial instrument, either directly or indirectly.

Level 3 – Significant unobservable inputs.

Table of Contents

Page 56

The methods and assumptions used to estimate the fair values of financial instruments are as follows:

The carrying value of short term investments approximates fair value due to the short maturities of these investments.

Fair values of fixed maturities are determined by management, utilizing prices obtained from a third party, nationally recognized pricing service or, in the case of securities for which prices are not provided by a pricing service, from third party brokers. For fixed maturities that have quoted prices in active markets, market quotations are provided. For fixed maturities that do not trade on a daily basis, the pricing service and brokers provide fair value estimates using a variety of inputs including, but not limited to, benchmark yields, reported trades, broker/dealer quotes, issuer spreads, bids, offers, reference data, prepayment rates and measures of volatility. Management reviews on an ongoing basis the reasonableness of the methodologies used by the relevant pricing service and brokers. In addition, management, using the prices received for the securities from the pricing service and brokers, determines the aggregate portfolio price performance and reviews it against applicable indices. If management believes that significant discrepancies exist, it will discuss these with the relevant pricing service or broker to resolve the discrepancies.

Fair values of equity securities are determined by management, utilizing quoted market prices.

Fair values of long term debt issued by Chubb are determined by management, utilizing prices obtained from a third party, nationally recognized pricing service.

At June 30, 2015 and December 31, 2014, a pricing service provided fair value amounts for approximately 99% of our fixed maturities. The prices we obtain from a pricing service and brokers generally are non-binding, but are reflective of current market transactions in the applicable financial instruments.

At June 30, 2015 and December 31, 2014, we held an insignificant amount of financial instruments in our investment portfolio for which a lack of market liquidity impacted our determination of fair value.

Item 3 - Quantitative and Qualitative Disclosures About Market Risk

For the Corporation's disclosures about market risk, see Item 7A in Part II of Chubb's Annual Report on Form 10-K for the year ended December 31, 2014. There have been no material changes to the Corporation's disclosures about market risk in Item 7A of Chubb's Annual Report on Form 10-K for the year ended December 31, 2014.

Item 4 - Controls and Procedures

As of June 30, 2015, an evaluation of the effectiveness of the design and operation of the Corporation's disclosure controls and procedures (as such term is defined in Rule 13a-15(e) of the Securities Exchange Act of 1934) was performed under the supervision and with the participation of the Corporation's management, including Chubb's chief executive officer and chief financial officer. Based on that evaluation, the chief executive officer and chief financial officer concluded that the Corporation's disclosure controls and procedures were effective as of June 30, 2015.

During the quarter ended June 30, 2015, there were no changes in internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, the Corporation's internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1 - Legal Proceedings

Chubb, the Board, ACE and/or Merger Sub have been named as defendants in ten putative class actions brought by purported Chubb shareholders challenging the Merger in the New Jersey Superior Court, Somerset County, Chancery Division. The suits are captioned The Sadie Nuay Charitable Found. v. The Chubb Corp., et al., C-012040-15 (filed July 10, 2015); Anne Cutler v. John D. Finnegan, et al., C-012041-15 (filed July 10, 2015); Sidney Weiman v. The Chubb Corp., et al., C-012043-15 (filed July 14, 2015); Renee Sayegh v. The Chubb Corp., et al., C-012045-15 (filed July 10, 2015); Judy Mesirov v. The Chubb Corp., et al., C-012046-15 (filed July 20, 2015); Shiva Stein v. The Chubb Corp., et al., C-012047-15 (filed July 21, 2015); Vladimir Gusinsky Living Trust v. The Chubb Corp., et al., C-012048-15 (filed July 22, 2015); Jane Schwartzman v. Zoe Baird Budinger, et al., C-012049-15 (filed July 20, 2015); Saunders v. The Chubb Corp., et al., C-012050-15 (filed July 23, 2015); and Polatsch v. The Chubb Corp., et al., C-012051-15 (filed July 23, 2015). The complaints allege, among other things, that the Board breached its fiduciary duties by agreeing to sell Chubb through an unfair and inadequate process and by failing to maximize the value of Chubb. Several of the complaints also allege that Chubb, ACE and/or Merger Sub have aided and abetted these breaches of fiduciary duties. Plaintiffs seek as relief, among other things, an injunction against the Merger, rescission of the Merger to the extent it is already implemented, and an award of damages. Chubb believes the lawsuits are without merit.

Chubb and its subsidiaries are defendants in various other lawsuits arising out of their businesses. It is the opinion of management that the final outcome of these matters will not materially affect the consolidated financial position of the registrant.

Item 1A - Risk Factors

For additional discussion of the Corporation's potential risks and uncertainties that could have a material adverse effect on our business, results of operations, profitability, financial condition, liquidity or cash flows and that could cause our operating results to vary significantly from period to period, see Item 1A in Part I of Chubb's Annual Report on Form 10-K for the year ended December 31, 2014 and the section entitled Risk Factors in the Registration Statement on Form S-4 filed by ACE relating to the Merger. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also could have a material adverse effect on our business, results of operations, profitability, financial condition, liquidity or cash flows.

Table of Contents

Page 59

We will be subject to business uncertainties while the Merger is pending, which could adversely affect our business.

Uncertainty about the effect of the Merger on our employees and customers may have an adverse effect on us. Additionally, the Merger is not expected to close until the first quarter of 2016 and may be delayed for any number of reasons, including those described in these Risk Factors. The length of time of the expected closing of the Merger and the uncertainties about the effect of the Merger on our employees and customers may impair our ability to attract, retain and motivate key personnel until the Merger is completed and for a period of time thereafter, and could cause customers and others that deal with us to seek to change their existing business relationships or cease doing business with us. Employee retention may be particularly challenging during the pendency of the Merger, as employees may experience uncertainty about their roles with ACE following the Merger and may become distracted as a result of such uncertainty.

In addition, the Merger Agreement restricts us from taking specified actions without the consent of ACE, and generally requires us to continue our operations in the ordinary course until completion of the Merger. These restrictions may prevent us from pursuing attractive business opportunities that may arise prior to the completion of the Merger or otherwise adversely affect our ability to do business.

We have incurred and will continue to incur transaction costs in connection with the Merger.

We have incurred and will continue to incur costs in connection with the negotiation and completion of the transactions contemplated by the Merger Agreement. Such costs include a portion of all filing fees paid to the Securities and Exchange Commission in connection with the Merger and the costs of printing and mailing a joint proxy statement/prospectus relating to special shareholder meetings at which ACE and Chubb shareholders will vote on Merger-related matters. We expect to continue to incur a number of other nonrecurring costs associated with completing the Merger, including, among others, fees paid to financial, legal, accounting and other advisors, which we have and will continue to incur, and employee retention costs. These costs, as well as other unanticipated costs and expenses, could have an adverse effect on our financial condition and results of operations prior to the completion of the Merger.

Regulatory approvals may not be received, may take longer than expected to be received or may impose conditions that are not presently anticipated or cannot be met.

Completion of the Merger is conditioned upon, among other things, the receipt of certain governmental approvals, including, without limitation, insurance regulatory approvals and the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. Although each party has agreed to use respective reasonable best efforts to obtain the requisite shareholder and governmental approvals, there can be no assurance that these approvals will be obtained and that the other conditions to completing the Merger will be satisfied. In addition, the governmental authorities from which the regulatory approvals are required may impose conditions on the completion of the Merger or require changes to the terms of the Merger or Merger Agreement. Such conditions or changes and the process of obtaining regulatory approvals could have the effect of delaying or impeding completion of the Merger.

Table of Contents

Page 60

Each party's obligation to complete the Merger is subject to the condition that the required governmental approvals have been obtained without the imposition of a condition or restriction that would reasonably be likely to have a material and adverse effect on ACE and its subsidiaries, taken as a whole, giving effect to the Merger (with such materiality measured on a scale relative to the Corporation, taken as a whole). Therefore, the Merger may not be completed if a regulator were to seek to impose such a condition or restriction.

The Merger Agreement limits our ability to pursue alternatives to the Merger.

The Merger Agreement contains provisions that may discourage a third party from submitting an acquisition proposal to Chubb that might result in greater value to Chubb shareholders than the Merger, or may result in a potential competing acquirer proposing to pay a lower per share price to acquire us than it might otherwise have proposed to pay. These provisions include a general prohibition on Chubb from soliciting or, subject to certain exceptions relating to the exercise of fiduciary duties by the Board, entering into discussions with any third party regarding any acquisition proposal or offers for competing transactions. Chubb also has an unqualified obligation to submit the proposal to approve the Merger to a vote by shareholders, even if an alternative acquisition proposal that the Board believes is superior to the Merger is received. In addition, Chubb may be required to pay ACE a termination fee of $930 million in certain circumstances involving acquisition proposals for competing transactions.

Failure to complete the Merger could negatively impact the price of Chubb common stock, as well as our future business and financial results.

The Merger Agreement contains a number of conditions that must be satisfied or waived prior to the completion of the Merger. Those conditions include: the approval of the Merger Agreement by Chubb shareholders, the approval of certain Merger-related proposals by ACE shareholders, the receipt of all required regulatory approvals and expiration or termination of all statutory waiting periods in respect thereof, the accuracy of representations and warranties under the Merger Agreement (subject to the materiality standards set forth in the Merger Agreement) and each party's performance of their respective obligations under the Merger Agreement in all material respects. There can be no assurance that all of the conditions to the Merger will be so satisfied or waived. If the conditions to the Merger are not satisfied or waived, ACE and Chubb will be unable to complete the Merger.

If the Merger is not completed for any reason, including the failure to receive the required approvals of ACE and/or Chubb shareholders, the Corporation's business and financial results may be adversely affected, including as follows:

we may experience negative reactions from the financial markets, including negative impacts on the market price of Chubb common stock;

the manner in which brokers, customers, insurers, cedants and other third parties perceive us may be negatively impacted, which in turn could affect our ability to compete for or write new business or obtain renewals in the marketplace;

Table of Contents

Page 61

we may experience negative reactions from employees; and

we will have expended time and resources that could otherwise have been spent on our existing business and the pursuit of other opportunities that could have been beneficial to our ongoing business and financial results may be adversely affected.

In addition to the above risks, if the Merger Agreement is terminated and/or the Board seeks an alternative transaction, Chubb's shareholders cannot be certain that we will be able to find a party willing to engage in a transaction on more attractive terms than the Merger. If the Merger Agreement is terminated under certain circumstances, Chubb may be required to pay a termination fee of $930 million to ACE.

The Merger Agreement may be terminated in accordance with its terms and the Merger may not be completed.

The Merger Agreement is subject to a number of conditions that must be fulfilled in order to complete the Merger. These conditions to the closing of the Merger may not be fulfilled in a timely manner or at all, and, accordingly, the Merger may be delayed or may not be completed. In addition, if the Merger is not completed by June 30, 2016, either ACE or Chubb may choose not to proceed with the Merger, and the parties can mutually decide to terminate the Merger Agreement at any time, before or after shareholder approval. In addition, ACE and Chubb may elect to terminate the Merger Agreement in certain other circumstances and Chubb may be required to pay a termination fee.

Our credit ratings and the financial strength ratings of our insurance subsidiaries may be adversely affected by the transactions contemplated by the Merger Agreement.

Credit ratings and financial strength ratings can be important factors in establishing our competitive position in the insurance markets. Following the announcement of the pending Merger, the rating agencies have undertaken a review of our debt ratings and our insurance company subsidiaries' financial strength ratings. The rating agencies may take various actions, positive or negative, and the result may not be known until the Merger closes. There can be no assurance that our ratings will continue for any given period of time or that they will not be changed. If our credit ratings were downgraded, we could incur higher borrowing costs and may have more limited means to access capital. In addition, a downgrade in our financial strength ratings could adversely affect the competitive position of our insurance operations, including a possible reduction in demand for our products in certain markets.

For additional information on our credit ratings and financial strength ratings, see Part I, Item 2 MD&A – Capital Resources and Liquidity - Ratings in this Form 10-Q and Part II, Item 7 MD&A – Capital Resources and Liquidity - Ratings in our Annual Report on Form 10-K for the year ended December 31, 2014.

Table of Contents

Page 62

Litigation relating to the Merger could require us to incur significant costs, as well as prevent and/or delay the Merger.

In connection with the Merger, purported Chubb shareholders have filed putative shareholder class action lawsuits against Chubb, members of the Board, ACE and Merger Sub. Among other remedies, the plaintiffs seek to enjoin the Merger. The outcome of any such litigation is uncertain. If the cases are not resolved, these lawsuits could prevent or delay completion of the Merger and result in substantial costs to us and ACE, including any costs associated with the indemnification of directors and officers. Plaintiffs may file additional lawsuits against Chubb, ACE and/or the directors and officers of either company in connection with the Merger. The defense or settlement of any lawsuit or claim that remains unresolved at the time the Merger is completed may adversely affect our business, results of operations, profitability, financial condition, liquidity or cash flows. For additional information on litigation relating to the Merger, see Part II, Item 1 Legal Proceedings in this Form 10-Q.

Because the market price of ACE common shares may fluctuate, Chubb shareholders cannot be certain of the precise value of the stock portion of the Merger consideration they may receive in the Merger.

At the time the Merger is completed, each issued and outstanding share of Chubb common stock (except for certain shares held by ACE, Chubb or their subsidiaries) will be converted into the right to receive consideration in the form of a combination of ACE common shares and cash.

There will be a time lapse between each of the date of the mailing of the joint proxy statement/prospectus relating to the Merger, the date on which Chubb shareholders vote on a proposal to approve the Merger Agreement at a special meeting of shareholders and the date on which Chubb shareholders entitled to receive ACE common shares actually receive such shares. The market value of ACE common shares may fluctuate during these periods as a result of a variety of factors, including general market and economic conditions, changes in ACE's businesses, operations and prospects and regulatory considerations. Many of these factors are outside the control of the Corporation and ACE. Consequently, at the time Chubb shareholders must decide whether to approve the Merger Agreement, they will not know the actual market value of the ACE common shares they will receive when the Merger is completed. The actual value of the ACE common shares received by Chubb shareholders will depend on the market value of the ACE common shares at that time. This market value may differ, possibly materially, from the value used in setting the Merger consideration. Chubb shareholders should obtain current stock quotations for ACE common shares before voting their shares of Chubb common stock.
