ACE Limited and Subsidiaries

1 . General

Basis of presentation

ACE Limited is a holding company incorporated in Zurich, Switzerland. ACE Limited, through its subsidiaries, provides a broad range of insurance and reinsurance products to insureds worldwide. ACE operates through five business segments: Insurance – North American P&C, Insurance – North American Agriculture, Insurance – Overseas General, Global Reinsurance, and Life. Refer to Note 10 for additional information.

The interim unaudited consolidated financial statements, which include the accounts of ACE Limited and its subsidiaries (collectively, ACE, we, us, or our), have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) and, in the opinion of management, reflect all adjustments (consisting of normally recurring accruals) necessary for a fair statement of the results and financial position for such periods. All significant intercompany accounts and transactions have been eliminated.

The results of operations and cash flows for any interim period are not necessarily indicative of the results for the full year. These consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in our 2013 Form 10-K.

2 . Acquisitions

Large Corporate P&C Insurance Business of Itaú Seguros, S.A. (Itaú Seguros)

On July 4, 2014, we announced that we reached a definitive agreement to acquire the large corporate property and casualty (P&C) insurance business of Itaú Seguros, Brazil's leading carrier for that business, for approximately $ 685 million , at current exchange rates. This transaction, which is subject to regulatory approval and other customary closing conditions, is expected to be completed in the first quarter of 2015.

The Siam Commercial Samaggi Insurance PCL (Samaggi)

We and our local partner acquired 60.86 percent of Samaggi, a general insurance company in Thailand, from Siam Commercial Bank on April 28, 2014, and subsequently acquired an additional 32.17 percent ownership, through a mandatory tender offer, which expired on June 17, 2014. The purchase price for 93.03 percent of the company was $ 176 million in cash. This acquisition expands our presence in Thailand and Southeast Asia.

The acquisition generated $ 46 million of goodwill, attributable to expected growth and profitability, none of which is expected to be deductible for income tax purposes, and other intangible assets of $ 80 million based on ACE’s preliminary purchase price allocation. The other intangible assets primarily relate to a bancassurance agreement. Goodwill and other intangible assets arising from this acquisition are included in the Insurance – Overseas General segment.

ABA Seguros

On May 2, 2013, we acquired ABA Seguros, a property and casualty insurer in Mexico that provides automobile, homeowners, and small business coverages for approximately $690 million in cash.

The acquisition generated $285 million of goodwill, attributable to expected growth and profitability, none of which is expected to be deductible for income tax purposes, and other intangible assets of $140 million based on ACE’s purchase price allocation. The other intangible assets primarily relate to distribution channels. Amortization of other intangible assets is included in Other (income) expense in the consolidated statements of operations. Goodwill and other intangible assets arising from this acquisition are included in the Insurance – Overseas General segment.

Fianzas Monterrey

On April 1, 2013, we acquired Fianzas Monterrey, a leading surety lines company in Mexico offering administrative performance bonds primarily to clients in the construction and industrial sectors, for approximately $293 million in cash. This acquisition greatly expanded our global franchise in the surety business and enhanced our existing commercial lines and personal accident insurance business in Mexico.

The acquisition generated $137 million of goodwill, attributable to expected growth and profitability, none of which is expected to be deductible for income tax purposes, and other intangible assets of $73 million , based on ACE's purchase price allocation. The other intangible assets primarily relate to customer lists. Amortization of other intangible assets is included in Other

maturities are reflected in Unrealized appreciation (depreciation) in the consolidated statement of shareholders’ equity. For the three and six months ended June 30, 2014 , $1 million and $5 million , respectively, of net unrealized appreciation related to such securities is included in OCI. For the three and six months ended June 30, 2013 , $1 million and $25 million , respectively, of net unrealized appreciation related to such securities is included in OCI. At June 30, 2014 and December 31, 2013 , AOCI includes cumulative net unrealized depreciation of $1 million and $4 million, respectively, related to securities remaining in the investment portfolio at those dates for which ACE has recognized a non-credit OTTI.

Mortgage-backed securities (MBS) issued by U.S. government agencies are combined with all other to be announced mortgage derivatives held (refer to Note 7 a) (iv)) and are included in the category, “Mortgage-backed securities”. Approximately 83 percent of the total mortgage-backed securities at June 30, 2014 and December 31, 2013 are represented by investments in U.S. government agency bonds. The remainder of the mortgage exposure consists of collateralized mortgage obligations and non-government mortgage-backed securities, the majority of which provide a planned structure for principal and interest payments and carry a rating of AAA by the major credit rating agencies.

than not that we will be required to sell the security before the recovery of its amortized cost. Further, in cases where we do not intend to sell the security and it is more likely than not that we will not be required to sell the security, ACE must evaluate the security to determine the portion of the impairment, if any, related to credit losses. If a credit loss is indicated, an OTTI is considered to have occurred and any portion of the OTTI related to credit losses must be reflected in Net income while the portion of OTTI related to all other factors is recognized in OCI. For fixed maturities held to maturity, OTTI recognized in OCI is accreted from AOCI to the amortized cost of the fixed maturity prospectively over the remaining term of the securities.

Each quarter, securities in an unrealized loss position (impaired securities), including fixed maturities, securities lending collateral, equity securities, and other investments, are reviewed to identify impaired securities to be specifically evaluated for a potential OTTI.

For all non-fixed maturities, OTTI is evaluated based on the following:

• the amount of time a security has been in a loss position and the magnitude of the loss position;

• the period in which cost is expected to be recovered, if at all, based on various criteria including economic conditions and other issuer-specific developments; and

• ACE’s ability and intent to hold the security to the expected recovery period.

As a general rule, we also consider that equity securities in an unrealized loss position for twelve consecutive months are other than temporarily impaired. For mutual funds included in equity securities in our consolidated balance sheet, we employ analysis similar to fixed maturities, when applicable.

We review each fixed maturity in an unrealized loss position to assess whether the security is a candidate for credit loss. Specifically, we consider credit rating, market price, and issuer-specific financial information, among other factors, to assess the likelihood of collection of all principal and interest as contractually due. Securities for which we determine that credit loss is likely are subjected to further analysis to estimate the credit loss recognized in Net income, if any. In general, credit loss recognized in Net income equals the difference between the security’s amortized cost and the net present value of its projected future cash flows discounted at the effective interest rate implicit in the debt security. All significant assumptions used in determining credit losses are subject to change as market conditions evolve.

Projected cash flows for corporate securities (principally senior unsecured bonds) are driven primarily by assumptions regarding probability of default and also the timing and amount of recoveries associated with defaults. ACE developed projected cash flows for corporate securities using market observable data, issuer-specific information, and credit ratings. We use historical default data by Moody’s Investors Service (Moody’s) rating category to calculate a 1-in-100 year probability of default, which results in a default assumption in excess of the historical mean default rate. Consistent with management's approach, ACE assumed a 32 percent recovery rate (the par value of a defaulted security that will be recovered) across all rating categories rather than using Moody's historical mean recovery rate of 42 percent. We believe that use of a default assumption in excess of the historical mean is conservative in light of current market conditions.

For the three and six months ended June 30, 2014 , credit losses recognized in Net income for corporate securities were $6 million and $10 million , respectively. For the three and six months ended June 30, 2013 , credit losses recognized in Net income for corporate securities were $6 million and $7 million , respectively.

For mortgage-backed securities, credit impairment is assessed using a cash flow model that estimates the cash flows on the underlying mortgages, using the security-specific collateral and transaction structure. The model estimates cash flows from the underlying mortgage loans and distributes those cash flows to various tranches of securities, considering the transaction structure and any subordination and credit enhancements that exist in that structure. The cash flow model incorporates actual cash flows on the mortgage-backed securities through the current period and then projects the remaining cash flows using a number of assumptions, including default rates, prepayment rates, and loss severity rates (the par value of a defaulted security that will not be recovered) on foreclosed properties.

For the three and six months ended June 30, 2014 and 2013 , there were no credit losses recognized in Net income for mortgage-backed securities.

d) Gross unrealized loss

At June 30, 2014 , there were 3,253 fixed maturities out of a total of 25,285 fixed maturities in an unrealized loss position. The largest single unrealized loss in the fixed maturities was $3 million. There were 52 equity securities out of a total of 186 equity securities in an unrealized loss position. The largest single unrealized loss in the equity securities was $42 million. Fixed maturities in an unrealized loss position at June 30, 2014 , comprised both investment grade and below investment grade securities for which fair value declined primarily due to widening credit spreads since the date of purchase. As of June 30, 2014 , there was one mutual fund, classified as an equity security investment, that was in a continuous unrealized loss position for more than twelve months where an other-than-temporary loss was not recorded. The unrealized loss of $ 42 million was approximately 8 percent of the original cost of the related equity security. We believe the impairment was temporary based on the relative price decline of the security and our intent and ability to hold the investment to its anticipated recovery.

e) Restricted assets

ACE is required to maintain assets on deposit with various regulatory authorities to support its insurance and reinsurance operations. These requirements are generally promulgated in the statutory regulations of the individual jurisdictions. The assets on deposit are available to settle insurance and reinsurance liabilities. ACE is also required to restrict assets pledged under repurchase agreements. We also use trust funds in certain large reinsurance transactions where the trust funds are set up for the benefit of the ceding companies and generally take the place of letter of credit (LOC) requirements. We also have investments in segregated portfolios primarily to provide collateral or guarantees for LOC and derivative transactions. Included in restricted assets at June 30, 2014 and December 31, 2013 , are investments, primarily fixed maturities, totaling $15.7 billion and $16.3 billion, respectively, and cash of $84 million and $162 million, respectively.

4 . Fair value measurements

a ) Fair value hierarchy

Fair value of financial assets and financial liabilities is estimated based on the framework established in the fair value accounting guidance. The guidance defines fair value as the price to sell an asset or transfer a liability (an exit price) in an orderly transaction between market participants and establishes a three-level valuation hierarchy based on the reliability of the inputs. The fair value hierarchy gives the highest priority to quoted prices in active markets and the lowest priority to unobservable data.

The three levels of the hierarchy are as follows:

• Level 1 – Unadjusted quoted prices for identical assets or liabilities in active markets;

• Level 2 – Includes, among other items, inputs other than quoted prices that are observable for the asset or liability such as

interest rates and yield curves, quoted prices for similar assets and liabilities in active markets, and quoted prices for identical or similar assets and liabilities in markets that are not active; and

• Level 3 – Inputs that are unobservable and reflect management’s judgments about assumptions that market participants

would use in pricing an asset or liability.

We categorize financial instruments within the valuation hierarchy at the balance sheet date based upon the lowest level of inputs that are significant to the fair value measurement. Accordingly, transfers between levels within the valuation hierarchy occur when there are significant changes to the inputs, such as increases or decreases in market activity, changes to the availability of current prices, changes to the transparency to underlying inputs, and whether there are significant variances in quoted prices. Transfers in and/or out of any level are assumed to occur at the end of the period.

We use pricing services to obtain fair value measurements for the majority of our investment securities. Based on management’s understanding of the methodologies used, these pricing services only produce an estimate of fair value if there is observable market information that would allow them to make a fair value estimate. Based on our understanding of the market inputs used by the pricing services, all applicable investments have been valued in accordance with GAAP. We do not adjust prices obtained from pricing services. The following is a description of the valuation techniques and inputs used to determine fair values for financial instruments carried at fair value, as well as the general classification of such financial instruments pursuant to the valuation hierarchy.

Fixed maturities

We use pricing services to estimate fair value measurements for the majority of our fixed maturities. The pricing services use market quotations for fixed maturities that have quoted prices in active markets; such securities are classified within Level 1. For fixed maturities other than U.S. Treasury securities that generally do not trade on a daily basis, the pricing services prepare estimates of fair value measurements using their pricing applications, which include available relevant market information, benchmark curves, benchmarking of like securities, sector groupings, and matrix pricing. Additional valuation factors that can be taken into account are nominal spreads, dollar basis, and liquidity adjustments. The pricing services evaluate each asset class based on relevant market and credit information, perceived market movements, and sector news. The market inputs used in the pricing evaluation, listed in the approximate order of priority include: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, reference data, and industry and economic events. The extent of the use of each input is dependent on the asset class and the market conditions. Given the asset class, the priority of the use of inputs may change, or some market inputs may not be relevant. Additionally, fixed maturities valuation is more subjective when markets are less liquid due to the lack of market based inputs (i.e., stale pricing), which may increase the potential that an investment's estimated fair value is not reflective of the price at which an actual transaction would occur. The overwhelming majority of fixed maturities are classified within Level 2 because the most significant inputs used in the pricing techniques are observable. For a small number of fixed maturities, we obtain a quote from a broker (typically a market maker). Due to the disclaimers on the quotes that indicate that the price is indicative only, we include these fair value estimates in Level 3.

Equity securities

Equity securities with active markets are classified within Level 1 as fair values are based on quoted market prices. For equity securities in markets which are less active, fair values are based on market valuations and are classified within Level 2. Equity securities for which pricing is unobservable are classified within Level 3.

ACE Limited and Subsidiaries

Short-term investments

Short-term investments, which comprise securities due to mature within one year of the date of purchase that are traded in active markets, are classified within Level 1 as fair values are based on quoted market prices. Securities such as commercial paper and discount notes are classified within Level 2 because these securities are typically not actively traded due to their approaching maturity and, as such, their cost approximates fair value. Short-term investments for which pricing is unobservable are classified within Level 3.

Other investments

Fair values for the majority of Other investments including investments in partially-owned investment companies, investment funds, and limited partnerships are based on their respective net asset values or equivalent (NAV). The majority of these investments, for which NAV was used as a practical expedient to measure fair value, are classified within Level 3 because either ACE will never have the contractual option to redeem the investments or will not have the contractual option to redeem the investments in the near term. The remainder of such investments is classified within Level 2. Certain of our long-duration contracts are supported by assets that do not qualify for separate account reporting under GAAP. These assets comprise mutual funds classified within Level 1 in the valuation hierarchy on the same basis as other equity securities traded in active markets. Other investments also includes equity securities and fixed maturities held in rabbi trusts maintained by ACE for deferred compensation plans, which are classified within the valuation hierarchy on the same basis as other equity securities and fixed maturities.

Securities lending collateral

The underlying assets included in Securities lending collateral in the consolidated balance sheets are fixed maturities which are classified in the valuation hierarchy on the same basis as other fixed maturities. Excluded from the valuation hierarchy is the corresponding liability related to ACE’s obligation to return the collateral plus interest as it is reported at contract value and not fair value in the consolidated balance sheets.

Investment derivative instruments

Actively traded investment derivative instruments, including futures, options, and forward contracts are classified within Level 1 as fair values are based on quoted market prices. The fair value of cross-currency swaps are based on market valuations and are classified within Level 2. Investment derivative instruments are recorded in either Other assets or Accounts payable, accrued expenses, and other liabilities in the consolidated balance sheets.

Other derivative instruments

We maintain positions in other derivative instruments including exchange-traded equity futures contracts and option contracts designed to limit exposure to a severe equity market decline, which would cause an increase in expected claims and, therefore, reserves for our guaranteed minimum death benefits (GMDB) and guaranteed living benefits (GLB) reinsurance business. Our position in exchange-traded equity futures contracts is classified within Level 1. The fair value of the majority of the remaining positions in other derivative instruments is based on significant observable inputs including equity security and interest rate indices. Accordingly, these are classified within Level 2. Other derivative instruments are recorded in either Other assets or Accounts payable, accrued expenses, and other liabilities in the consolidated balance sheets.

Separate account assets

Separate account assets represent segregated funds where investment risks are borne by the customers, except to the extent of certain guarantees made by ACE. Separate account assets comprise mutual funds classified in the valuation hierarchy on the same basis as other equity securities traded in active markets and are classified within Level 1. Separate account assets also include fixed maturities classified within Level 2 because the most significant inputs used in the pricing techniques are observable. Excluded from the valuation hierarchy are the corresponding liabilities as they are reported at contract value and not fair value in the consolidated balance sheets. Separate account assets are recorded in Other assets in the consolidated balance sheets.

Guaranteed living benefits

The GLB arises from life reinsurance programs covering living benefit guarantees whereby we assume the risk of guaranteed minimum income benefits (GMIB) and guaranteed minimum accumulation benefits (GMAB) associated with variable annuity contracts. GLB’s are recorded in Accounts payable, accrued expenses, and other liabilities and Future policy benefits in the consolidated balance sheets. For GLB reinsurance, ACE estimates fair value using an internal valuation model which includes current market information and estimates of policyholder behavior. All of the treaties contain claim limits, which are factored into the valuation model. The fair value depends on a number of inputs, including changes in interest rates, changes in equity

markets, credit risk, current account value, changes in market volatility, expected annuitization rates, changes in policyholder behavior, and changes in policyholder mortality.

The most significant policyholder behavior assumptions include lapse rates and the GMIB annuitization rates. Assumptions regarding lapse rates and GMIB annuitization rates differ by treaty, but the underlying methodologies to determine rates applied to each treaty are comparable. The assumptions regarding lapse and GMIB annuitization rates determined for each treaty are based on a dynamic calculation that uses several underlying factors.

A lapse rate is the percentage of in-force policies surrendered in a given calendar year. All else equal, as lapse rates increase, ultimate claim payments will decrease.

GMIB annuitization rate is the percentage of policies for which the policyholder will elect to annuitize using the guaranteed benefit provided under the GMIB. All else equal, as GMIB annuitization rates increase, ultimate claim payments will increase, subject to treaty claim limits.

The effect of changes in key market factors on assumed lapse and annuitization rates reflect emerging trends using data available from cedants. For treaties with limited experience, rates are established in line with data received from other ceding companies adjusted, as appropriate, with industry estimates. The model and related assumptions are continuously re-evaluated by management and enhanced, as appropriate, based upon additional experience obtained related to policyholder behavior and availability of more information, such as market conditions, market participant assumptions, and demographics of in-force annuities. During the three and six months ended June 30, 2014 , no material changes were made to actuarial or behavioral assumptions. We made minor technical refinements to the model with a favorable (unfavorable) net income impact of approximately $1 million and $ (2) million for the three and six months ended June 30, 2014 , respectively. For detailed information on our lapse and annuitization rate assumptions, refer to Note 4 to the Consolidated Financial Statements of our 2013 Form 10-K.

We view the variable annuity reinsurance business as having a similar risk profile to that of catastrophe reinsurance, with the probability of a cumulative long-term economic net loss relatively small at the time of pricing. However, adverse changes in market factors and policyholder behavior will have an adverse impact on net income, which may be material. Because of the significant use of unobservable inputs including policyholder behavior, GLB reinsurance is classified within Level 3.

Investment funds

ACE’s investment funds employ various investment strategies such as long/short equity and arbitrage/distressed. Included in this category are investments for which ACE has the option to redeem at agreed upon value as described in each investment fund’s subscription agreement. Depending on the terms of the various subscription agreements, investment fund investments may be redeemed monthly, quarterly, semi-annually, or annually. If ACE wishes to redeem an investment fund investment, it must first determine if the investment fund is still in a lock-up period (a time when ACE cannot redeem its investment so that the investment fund manager has time to build the portfolio). If the investment fund is no longer in its lock-up period, ACE must then notify the investment fund manager of its intention to redeem by the notification date prescribed by the subscription agreement. Subsequent to notification, the investment fund can redeem ACE’s investment within several months of the notification. Notice periods for redemption of the investment funds range between 5 and 120 days. ACE can redeem its investment funds without consent from the investment fund managers.

Level 3 financial instruments

The fair values of assets and liabilities measured at fair value using significant unobservable inputs (Level 3) consist of various inputs and assumptions that management makes when determining fair value. Management analyzes changes in fair value measurements classified within Level 3 by comparing pricing and returns of our investments to benchmarks, including month-over-month movements, investment credit spreads, interest rate movements, and credit quality of securities.

b) Financial instruments disclosed, but not measured, at fair value

ACE uses various financial instruments in the normal course of its business. Our insurance contracts are excluded from fair value of financial instruments accounting guidance, and therefore, are not included in the amounts discussed below.

The carrying values of cash, other assets, other liabilities, and other financial instruments not included below approximated their fair values.

Investments in partially-owned insurance companies

Fair values for investments in partially-owned insurance companies are based on ACE’s share of the net assets based on the financial statements provided by those companies.

Short- and long-term debt and trust preferred securities

Where practical, fair values for short-term debt, long-term debt, and trust preferred securities are estimated using discounted cash flow calculations based principally on observable inputs including incremental borrowing rates, which reflect ACE’s credit rating, for similar types of borrowings with maturities consistent with those remaining for the debt being valued.

Net (increase) decrease in liability	$ (3	)	$ 105	$ (59	)	$ 472

Net realized gains (losses) in the table above include gains (losses) related to foreign exchange and fair value adjustments on insurance derivatives and exclude gains (losses) on S&P put options and futures held to partially offset the risk in the GLB reinsurance portfolio. Refer to Note 7 for additional information.

At June 30, 2014 , reported liabilities for GMDB and GLB reinsurance were $107 million and $486 million, respectively, compared with $100 million and $427 million, respectively, at December 31, 2013 . The reported liability for GLB reinsurance of $486 million at June 30, 2014 , and $427 million at December 31, 2013 , includes a fair value derivative adjustment of $ 241 million and $193 million, respectively. Reported liabilities for both GMDB and GLB reinsurance are determined using internal valuation models. Such valuations require considerable judgment and are subject to significant uncertainty. The valuation of these products is subject to fluctuations arising from, among other factors, changes in interest rates, changes in equity markets, changes in credit markets, changes in the allocation of the investments underlying annuitants’ account values, and assumptions regarding future policyholder behavior. These models and the related assumptions are continually reviewed by management and enhanced, as appropriate, based upon improvements in modeling assumptions and availability of more information, such as market conditions and demographics of in-force annuities.

Variable Annuity Net Amount at Risk

(i) Reinsurance covering the GMDB risk only

At June 30, 2014 and December 31, 2013 , the net amount at risk from reinsurance programs covering the GMDB risk only was $601 million and $586 million, respectively.

For reinsurance programs covering the GMDB risk only, the net amount at risk is defined as the present value of future claim payments under the following assumptions:

• policy account values and guaranteed values are fixed at the valuation date ( June 30, 2014 and December 31, 2013 , respectively);

• there are no lapses or withdrawals;

• mortality according to 100 percent of the Annuity 2000 mortality table;

• future claims are discounted in line with the discounting assumption used in the calculation of the benefit reserve averaging between 1.5 percent and 2.5 percent ; and

• reinsurance coverage ends at the earlier of the maturity of the underlying variable annuity policy or the reinsurance treaty.

The total claim amount payable on reinsurance programs covering the GMDB risk only, if all the cedants’ policyholders were to die immediately at June 30, 2014 was approximately $676 million. This takes into account all applicable reinsurance treaty claim limits.

*Table of Contents*

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – continued (Unaudited)

ACE Limited and Subsidiaries

(ii) Reinsurance covering the GLB risk only

At June 30, 2014 and December 31, 2013 , the net amount at risk from reinsurance programs covering the GLB risk only was $173 million and $136 million, respectively.

For reinsurance programs covering the GLB risk only, the net amount at risk is defined as the present value of future claim payments under the following assumptions:

• policy account values and guaranteed values are fixed at the valuation date ( June 30, 2014 and December 31, 2013 , respectively);

• there are no deaths, lapses, or withdrawals;

• policyholders annuitize at a frequency most disadvantageous to ACE (in other words, annuitization at a level that maximizes claims taking into account the treaty limits) under the terms of the reinsurance contracts;

• for annuitizing policyholders, the GMIB claim is calculated using interest rates in line with those used in calculating the reserve;

• future claims are discounted in line with the discounting assumption used in the calculation of the benefit reserve averaging between 3.5 percent and 4.5 percent; and

• reinsurance coverage ends at the earlier of the maturity of the underlying variable annuity policy or the reinsurance treaty.

(iii) Reinsurance covering both the GMDB and GLB risks on the same underlying policyholders

At June 30, 2014 and December 31, 2013 , the GMDB net amount at risk from reinsurance programs covering both the GMDB and GLB risks on the same underlying policyholders was $69 million and $ 73 million , respectively.

At June 30, 2014 and December 31, 2013 , the GLB net amount at risk from reinsurance programs covering both the GMDB and GLB risks on the same underlying policyholders was $142 million and $141 million, respectively.

These net amounts at risk reflect the interaction between the two types of benefits on any single policyholder (eliminating double-counting), and therefore the net amounts at risk should be considered additive.

For reinsurance programs covering both the GMDB and GLB risks on the same underlying policyholders, the net amount at risk is defined as the present value of future claim payments under the following assumptions:

• policy account values and guaranteed values are fixed at the valuation date ( June 30, 2014 and December 31, 2013 , respectively);

• there are no lapses or withdrawals;

• mortality according to 100 percent of the Annuity 2000 mortality table;

• for annuitizing policyholders, the GMIB claim is calculated using interest rates in line with those used in calculating the reserve;

• future claims are discounted in line with the discounting assumption used in the calculation of the benefit reserve averaging between 3.0 percent and 4.0 percent; and

• reinsurance coverage ends at the earlier of the maturity of the underlying variable annuity policy or the reinsurance treaty.

The total claim amount payable on reinsurance programs covering both the GMDB and GLB risks on the same underlying policyholders, if all of the cedants’ policyholders were to die immediately at June 30, 2014 was approximately $ 64 million . This takes into account all applicable reinsurance treaty claim limits. Although there would be an increase in death claims resulting from 100 percent immediate mortality of all policyholders, the GLB claims would be zero.

The average attained age of all policyholders under sections i), ii), and iii) above, weighted by the guaranteed value of each reinsured policy, is approximately 69 years.

6 . Debt

In May 2014, ACE INA Holdings Inc. issued $ 700 million of 3.35 percent senior notes due May 2024. These senior notes are redeemable at any time at ACE INA Holdings Inc.'s option subject to a “make-whole” premium (the present value of the remaining principal and interest discounted at the applicable U.S. Treasury rate plus 0.15 percent). The notes are also

*Table of Contents*

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – continued (Unaudited)

ACE Limited and Subsidiaries

redeemable at par plus accrued and unpaid interest in the event of certain changes in tax law. These notes do not have the benefit of any sinking fund. These senior unsecured notes are guaranteed on a senior basis by ACE Limited and they rank equally with all of ACE's other senior obligations. They also contain customary limitations on lien provisions as well as customary events of default provisions which, if breached, could result in the accelerated maturity of such senior debt.

In May 2014, we reclassified ACE INA Holdings Inc.'s $ 450 million of 5.6 percent senior notes, due to mature on May 15, 2015, from Long-term debt to Short-term debt in the consolidated balance sheet.

In June 2014, ACE INA Holdings Inc.'s $ 500 million of 5.875 percent senior notes matured and were fully paid.

7 . Commitments, contingencies, and guarantees

a) Derivative instruments

Derivative instruments employed

ACE maintains positions in derivative instruments such as futures, options, swaps, and foreign currency forward contracts for which the primary purposes are to manage duration and foreign currency exposure, yield enhancement, or to obtain an exposure to a particular financial market. ACE also maintains positions in convertible securities that contain embedded derivatives. Investment derivative instruments are recorded in either Other assets (OA) or Accounts payable, accrued expenses, and other liabilities (AP), convertible bonds are recorded in Fixed maturities available for sale (FM AFS) and convertible equity securities are recorded in Equity securities (ES) in the consolidated balance sheets. These are the most numerous and frequent derivative transactions.

In addition, ACE from time to time purchases to be announced mortgage-backed securities (TBAs) as part of its investing activities.

Under reinsurance programs covering GLBs, ACE assumes the risk of GLBs, including GMIB and GMAB, associated with variable annuity contracts. The GMIB risk is triggered if, at the time the contract holder elects to convert the accumulated account value to a periodic payment stream (annuitize), the accumulated account value is not sufficient to provide a guaranteed minimum level of monthly income. The GMAB risk is triggered if, at contract maturity, the contract holder’s account value is less than a guaranteed minimum value. The GLB reinsurance product meets the definition of a derivative instrument. Benefit reserves in respect of GLBs are classified as Future policy benefits (FPB) while the fair value derivative adjustment is classified within AP. ACE also maintains positions in exchange-traded equity futures contracts and options on equity market indices to limit equity exposure in the GMDB and GLB blocks of business.

In relation to certain debt issuances, ACE from time to time enters into interest rate swap transactions for the purpose of either fixing or reducing borrowing costs. Although the use of these interest rate swaps has the economic effect of fixing or reducing borrowing costs on a net basis, gross interest expense on the related debt issuances is included in Interest expense while the settlements related to the interest rate swaps are reflected in Net realized gains (losses) in the consolidated statements of operations. At June 30, 2014 , ACE had no in-force interest rate swaps.

All derivative instruments are carried at fair value with changes in fair value recorded in Net realized gains (losses) in the consolidated statements of operations. None of the derivative instruments are designated as hedges for accounting purposes.

At June 30, 2014 and December 31, 2013, derivative liabilities of $14 million and $41 million , respectively, included in the table above were subject to a master netting agreement. The remaining derivatives included in the table above were not subject to a master netting agreement.

At both June 30, 2014 and December 31, 2013, our repurchase obligations of $1,401 million were fully collateralized. At June 30, 2014 and December 31, 2013, our securities lending payable was $1,441 million and $1,633 million, respectively, and our securities lending collateral was $1,440 million and $1,632 million, respectively. The securities lending collateral can only be accessed in the event that the institution borrowing the securities is in default under the lending agreement. An indemnification agreement with the lending agent protects us in the event a borrower becomes insolvent or fails to return any of the securities on loan. In contrast to securities lending programs, the use of cash received is not restricted for the repurchase obligations.

Derivative instrument objectives

(i) Foreign currency exposure management

A foreign currency forward contract (forward) is an agreement between participants to exchange specific foreign currencies at a future date. ACE uses forwards to minimize the effect of fluctuating foreign currencies.

(ii) Duration management and market exposure

Futures

Futures contracts give the holder the right and obligation to participate in market movements, determined by the index or underlying security on which the futures contract is based. Settlement is made daily in cash by an amount equal to the change in value of the futures contract times a multiplier that scales the size of the contract. Exchange-traded futures contracts on money market instruments, notes and bonds are used in fixed maturity portfolios to more efficiently manage duration, as substitutes for ownership of the money market instruments, bonds and notes without significantly increasing the risk in the portfolio. Investments in futures contracts may be made only to the extent that there are assets under management not otherwise committed.

Exchange-traded equity futures contracts are used to limit exposure to a severe equity market decline, which would cause an increase in expected claims and therefore, reserves for GMDB and GLB reinsurance business.

Options

An option contract conveys to the holder the right, but not the obligation, to purchase or sell a specified amount or value of an underlying security at a fixed price. Option contracts are used in the investment portfolio as protection against unexpected shifts in interest rates, which would affect the duration of the fixed maturity portfolio. By using options in the portfolio, the overall interest rate sensitivity of the portfolio can be reduced. Option contracts may also be used as an alternative to futures contracts in the synthetic strategy as described above.

Another use for option contracts is to limit exposure to a severe equity market decline, which would cause an increase in expected claims and therefore, reserves for GMDB and GLB reinsurance business.

The price of an option is influenced by the underlying security, expected volatility, time to expiration, and supply and demand.

The credit risk associated with the above derivative financial instruments relates to the potential for non-performance by counterparties. Although non-performance is not anticipated, in order to minimize the risk of loss, management monitors the

creditworthiness of its counterparties and obtains collateral. The performance of exchange-traded instruments is guaranteed by the exchange on which they trade. For non-exchange-traded instruments, the counterparties are principally banks which must meet certain criteria according to our investment guidelines.

Cross-currency swaps

Cross-currency swaps are agreements under which two counterparties exchange interest payments and principal denominated in different currencies at a future date. We use cross-currency swaps to reduce the foreign currency and interest rate risk by converting cash flows back into local currency. We invest in foreign currency denominated investments to improve credit diversification and also to obtain better duration matching to our liabilities that is limited in the local currency market.

Other

Included within Other are derivatives intended to reduce potential losses which may arise from certain exposures in our insurance business. The economic benefit provided by these derivatives is similar to purchased reinsurance. For example, from time to time ACE may enter into crop derivative contracts to protect underwriting results in the event of a significant decline in commodity prices. Also included within Other are certain life insurance products that meet the definition of a derivative instrument for accounting purposes.

(iii) Convertible security investments

A convertible security is a debt instrument or preferred stock that can be converted into a predetermined amount of the issuer’s equity. The convertible option is an embedded derivative within the host instruments which are classified in the investment portfolio as either available for sale or as an equity security. ACE purchases convertible securities for their total return and not specifically for the conversion feature.

(iv) TBA

By acquiring TBAs, we make a commitment to purchase a future issuance of mortgage-backed securities. For the period between purchase of the TBAs and issuance of the underlying security, we account for our position as a derivative in the consolidated financial statements. ACE purchases TBAs both for their total return and for the flexibility they provide related to our mortgage-backed security strategy.

(v) GLB

Under the GLB program, as the assuming entity, ACE is obligated to provide coverage until the expiration or maturity of the underlying deferred annuity contracts or the expiry of the reinsurance treaty. Premiums received under the reinsurance treaties are classified as premium. Expected losses allocated to premiums received are classified as Future policy benefits and valued similar to GMDB reinsurance. Other changes in fair value, principally arising from changes in expected losses allocated to expected future premiums, are classified as Net realized gains (losses). Fair value represents management’s estimate of exit price and thus, includes a risk margin. We may recognize a realized loss for other changes in fair value due to adverse changes in the capital markets (e.g., declining interest rates and/or declining equity markets) and changes in actual or estimated future policyholder behavior (e.g., increased annuitization or decreased lapse rates) although we expect the business to be profitable. We believe this presentation provides the most meaningful disclosure of changes in the underlying risk within the GLB reinsurance programs for a given reporting period.

b) Other investments

At June 30, 2014 , included in Other investments in the consolidated balance sheet are investments in limited partnerships and partially-owned investment companies with a carrying value of $2.1 billion. In connection with these investments, we have commitments that may require funding of up to $1.0 billion over the next several years.

c) Taxation

As of June 30, 2014 , $27 million of unrecognized tax benefits remains outstanding. It is reasonably possible that over the next twelve months, the amount of unrecognized tax benefits may change resulting from the re-evaluation of unrecognized tax benefits arising from examinations of taxing authorities. With few exceptions, ACE is no longer subject to state and local or non-U.S. income tax examinations for years before 2005.

d) Letters of credit

We did not renew our $ 500 million bilateral letter of credit facility that expired in June 2014. We elected instead to satisfy our collateral obligations primarily with insurance trusts supported by our investment portfolio.

e) Legal proceedings

Our insurance subsidiaries are subject to claims litigation involving disputed interpretations of policy coverages and, in some jurisdictions, direct actions by allegedly-injured persons seeking damages from policyholders. These lawsuits, involving claims on policies issued by our subsidiaries which are typical to the insurance industry in general and in the normal course of business, are considered in our loss and loss expense reserves. In addition to claims litigation, we are subject to lawsuits and regulatory actions in the normal course of business that do not arise from or directly relate to claims on insurance policies. This category of business litigation typically involves, among other things, allegations of underwriting errors or misconduct, employment claims, regulatory activity, or disputes arising from our business ventures. In the opinion of management, our ultimate liability for these matters could be, but we believe is not likely to be, material to our consolidated financial condition and results of operations.

8 . Shareholders’ equity

All of ACE’s Common Shares are authorized under Swiss corporate law. Though the par value of Common Shares is stated in Swiss francs, ACE continues to use U.S. dollars as its reporting currency for preparing consolidated financial statements. Under Swiss corporate law, dividends, including distributions through a reduction in par value (par value reduction) or from legal reserves, must be stated in Swiss francs though dividend payments are made by ACE in U.S. dollars. At our May 2013 and May 2014 annual general meetings, our shareholders approved a dividend for the following year, respectively, payable in four quarterly installments after the annual general meetings in the form of a distribution by way of a par value reduction. At the January 10, 2014 Extraordinary General Meeting, our shareholders approved a resolution to increase our quarterly dividend from $ 0.51 per share to $0.63 per share for the final two quarterly installments (made on January 31, 2014 and April 17, 2014) that had been earlier approved at our 2013 annual general meeting. The $0.12 per share increase for each installment was distributed from capital contribution reserves (Additional paid-in capital), a subaccount of legal reserves, and transferred to free reserves (Retained earnings) for payment, while the existing $ 0.51 per share was distributed by way of a par value reduction.

For the three and six months ended June 30, 2014 , dividends per Common Share amounted to CHF 0.58 ($ 0.65 ) and CHF 1.23 ($ 1.40 ), respectively. For the six months ended June 30, 2014 , dividends included a distribution from capital contribution reserves of CHF 0.20 ($ 0.24 ). Par value reductions have been reflected as such through Common Shares in the consolidated statements of shareholders' equity and had the effect of reducing par value per Common Share to CHF 26.01 at June 30, 2014 .

For the three and six months ended June 30, 2013 , dividends per Common Share amounted to CHF 0.48 ($ 0.51 ) and CHF 0.94 ($ 1.00 ).

Common Shares in treasury are used principally for issuance upon the exercise of employee stock options, grants of restricted stock, and purchases under the Employee Stock Purchase Plan (ESPP). At June 30, 2014 , 6,606,823 Common Shares remain in treasury after net shares redeemed under employee share-based compensation plans.

ACE Limited securities repurchase authorization

For the three and six months ended June 30, 2014 , ACE repurchased 2,306,000 and 5,793,882 Common Shares for a cost of $237 million and $ 569 million , respectively, in a series of open market transactions under the November 2013 Board authorization of a share repurchase program of up to $2.0 billion of ACE's Common Shares through December 31, 2014 . At June 30, 2014 , $ 1.37 billion in share repurchase authorization remained through December 31, 2014 pursuant to the Board authorization. For the period July 1, 2014 through July 29, 2014 , ACE repurchased 1,281,630 Common Shares for a total of $133 million in a series of open market transactions. At July 29, 2014 , $1.24 billion in share repurchase authorization remained through December 31, 2014 .

9 . Share-based compensation

The ACE Limited 2004 Long-Term Incentive Plan (the 2004 LTIP) permits grants of both incentive and non-qualified stock options principally at an option price per share equal to the grant date fair value of ACE’s Common Shares. Stock options are generally granted with a 3-year vesting period and a 10-year term. Stock options typically vest in equal annual installments over the vesting period, which is also the requisite service period. On February 27, 2014 , ACE granted 1,779,074 stock options with a weighted-average grant date fair value of $18.00 each. The fair value of the options issued is estimated on the date of grant using the Black-Scholes option pricing model.

*Table of Contents*

ACE Limited and Subsidiaries

The 2004 LTIP also permits grants of restricted stock and restricted stock units. ACE generally grants restricted stock and restricted stock units with a 4-year vesting period, based on a graded vesting schedule. The restricted stock is granted at market close price on the grant date. On February 27, 2014 , ACE granted 1,492,290 restricted stock awards and 276,992 restricted stock units to employees and officers with a grant date fair value of $96.76 each. Each restricted stock unit represents our obligation to deliver to the holder one Common Share upon vesting.

10 . Segment information

ACE operates through five business segments: Insurance – North American P&C, Insurance – North American Agriculture, Insurance – Overseas General, Global Reinsurance, and Life. These segments distribute their products through various forms of brokers, agencies, and direct marketing programs. All business segments have established relationships with reinsurance intermediaries.

For segment reporting purposes, certain items have been presented in a different manner below than in the consolidated financial statements. Management uses underwriting income as the main measure of segment performance. ACE calculates underwriting income by subtracting Losses and loss expenses, Policy benefits, Policy acquisition costs, and Administrative expenses from Net premiums earned. For the Insurance – North American Agriculture segment, management includes gains and losses from fair value changes on crop derivatives as a component of underwriting income. For example, for the three months ended June 30, 2014 , underwriting income in our Insurance – North American Agriculture segment was $27 million . This amount includes $8 million of realized gains related to crop derivatives which are included in Net realized gains (losses) below. For the Life segment, management includes Net investment income and (Gains) losses from fair value changes in separate account assets that do not qualify for separate account reporting under GAAP as components of Life underwriting income. For example, for the three months ended June 30, 2014 , Life underwriting income of $ 89 million includes Net investment income of $ 66 million and gains from fair value changes in separate account assets of $ 17 million.

12 . Information provided in connection with outstanding debt of subsidiaries

The following tables present condensed consolidating financial information at June 30, 2014 and December 31, 2013 , and for the three and six months ended June 30, 2014 and 2013 for ACE Limited (Parent Guarantor) and ACE INA Holdings Inc. (Subsidiary Issuer). The Subsidiary Issuer is an indirect 100 percent-owned subsidiary of the Parent Guarantor. The Parent Guarantor fully and unconditionally guarantees certain of the debt of the Subsidiary Issuer.

During the third quarter of 2013 , we determined that the Subsidiary Issuer columns presented in the previously issued condensed consolidating financial information should be presented on the equity method of accounting rather than on a consolidated basis. Accordingly, we have revised the disclosure to correct the Condensed Consolidating Statement of Operations and Comprehensive Income for the three and six months ended June 30, 2013 and the Condensed Consolidating Statement of Cash Flows for the six months ended June 30, 2013 . As a result of this revision to the Subsidiary Issuer condensed consolidating financial information, revenues and expenses and cash flows of the subsidiaries of ACE INA Holdings Inc. (Subsidiary Issuer) are now presented in the Other ACE Limited Subsidiaries column on a combined basis. In addition, we revised the Consolidating Adjustments and Eliminations column to correctly include all intercompany eliminations. Previously, this column reflected only ACE Limited parent company intercompany eliminations. We also revised the Condensed Consolidating Statement of Cash Flows for the six months ended June 30, 2013 to correct the presentation of negative cash associated with our affiliated notional cash pooling programs (Pools). In addition, certain items in the Condensed Consolidating Statement of Cash Flows for the six months ended June 30, 2013 have been reclassified to conform to current period presentation. Also, the operating cash flows have been corrected to properly reflect certain intercompany transactions previously recorded in financing cash flows for the six months ended June 30, 2013 .

Total shareholders' equity and net income of the Subsidiary Issuer and Parent Guarantor were not impacted as a result of these revisions. The impact of the revisions was not material to the prior period consolidated financial statements taken as a whole. There was no impact on the consolidated amounts previously reported.

(1) ACE maintains two notional multicurrency cash pools (Pools) with a third-party bank. Various ACE entities participate in one or the other of the Pools, pursuant to which credit and debit balances in individual ACE accounts are translated daily into a single currency and pooled on a notional basis. Individual ACE entities are permitted to overdraw on their individual accounts provided the overall Pool balances do not fall below zero. At June 30, 2014 , the cash balance of one or more entities was negative; however, the overall Pool balances were positive.

Individual ACE entities are permitted to overdraw on their individual accounts provided the overall Pool balances do not fall below zero. At December 31, 2013 , the cash balance of one or more entities was negative; however, the overall Pool balances were positive.

Forward-Looking Statements

The Private Securities Litigation Reform Act of 1995 provides a “safe harbor” for forward-looking statements. Any written or oral statements made by us or on our behalf may include forward-looking statements that reflect our current views with respect to future events and financial performance. These forward-looking statements are subject to certain risks, uncertainties, and other factors that could, should potential events occur, cause actual results to differ materially from such statements. These risks, uncertainties, and other factors, which are described in more detail elsewhere herein and in other documents we file with the U.S. Securities and Exchange Commission (SEC), include but are not limited to:

• losses arising out of natural or man-made catastrophes such as hurricanes, typhoons, earthquakes, floods, climate change (including effects on weather patterns; greenhouse gases; sea; land and air temperatures; sea levels; and rain and snow), nuclear accidents, or terrorism which could be affected by:

• the number of insureds and ceding companies affected;

• the amount and timing of losses actually incurred and reported by insureds;

• the impact of these losses on our reinsurers and the amount and timing of reinsurance recoverable actually received;

• the cost of building materials and labor to reconstruct properties or to perform environmental remediation following a catastrophic event; and

• complex coverage and regulatory issues such as whether losses occurred from storm surge or flooding and related lawsuits;

• actions that rating agencies may take from time to time, such as financial strength or credit ratings downgrades or placing these ratings on credit watch negative or the equivalent;

• the ability to collect reinsurance recoverable, credit developments of reinsurers, and any delays with respect thereto and changes in the cost, quality, or availability of reinsurance;

• actual loss experience from insured or reinsured events and the timing of claim payments;

• the uncertainties of the loss-reserving and claims-settlement processes, including the difficulties associated with assessing environmental damage and asbestos-related latent injuries, the impact of aggregate-policy-coverage limits, the impact of bankruptcy protection sought by various asbestos producers and other related businesses, and the timing of loss payments;

• changes to our assessment as to whether it is more likely than not that we will be required to sell, or have the intent to sell, available for sale fixed maturity investments before their anticipated recovery;

• infection rates and severity of pandemics and their effects on our business operations and claims activity;

• developments in global financial markets, including changes in interest rates, stock markets, and other financial markets, increased government involvement or intervention in the financial services industry, the cost and availability of financing, and foreign currency exchange rate fluctuations (which we refer to in this report as foreign exchange and foreign currency exchange), which could affect our statement of operations, investment portfolio, financial condition, and financing plans;

• general economic and business conditions resulting from volatility in the stock and credit markets and the depth and duration of potential recession;

• global political conditions, the occurrence of any terrorist attacks, including any nuclear, radiological, biological, or chemical events, or the outbreak and effects of war, and possible business disruption or economic contraction that may result from such events;

(1) On a constant-dollar basis. Amounts are calculated by translating prior period results using the same local currency rates as the comparable current period.

Net premiums written reflect the premiums we retain after purchasing reinsurance protection. Net premiums written increased for the three months ended June 30, 2014 in our Insurance – Overseas General segment on a constant-dollar basis from new business writings in all product lines – A&H, personal lines, and P&C. In addition, the acquisitions of ABA Seguros in May 2013 and Samaggi in April 2014 added to premium growth. The impact of foreign exchange adversely impacted growth on an as reported basis. Our Insurance – North American P&C segment also reported increases in net premiums written in our retail division from growth across a broad range of our product portfolio including our risk management business, surety, professional, general and specialty casualty, and A&H lines of business reflecting higher production and strong renewal retention. In addition, we grew net premiums written in our Commercial Risk Services division, primarily specialty and program business, and our personal lines division, primarily in the homeowners and automobile business offered through ACE Private Risk Services. Our wholesale and specialty division contributed to the increase in net premiums written from higher production in our property, casualty, and professional lines of business. Our Insurance – North American Agriculture segment reported a decrease in net premiums written primarily due to lower Multiple Peril Crop Insurance (MPCI) production reflecting lower commodity prices, partially offset by higher premium retention primarily as a result of the non-renewal of a third-party proportional reinsurance agreement.

For the six months ended June 30, 2014, net premiums written increased in our Insurance – Overseas General and Insurance – North American P&C segments due primarily to the factors described above. The acquisition of Fianzas Monterrey in April 2013 also added to premium growth in our Insurance – Overseas General segment. In addition, net premiums written increased in our Insurance – North American Agriculture segment, primarily due to decreased premium cessions to the U.S. government and to third-party reinsurers.

Net premiums earned for short-duration contracts, typically P&C contracts, generally reflect the portion of net premiums written that were recorded as revenues for the period as the exposure periods expire. Net premiums earned for long-duration contracts,

*Table of Contents*

typically traditional life contracts, generally are recognized as earned when due from policyholders. Net premiums earned increased for the three and six months ended June 30, 2014 primarily due to the increase in net premiums written as described above.

In evaluating our segments excluding Life, we use the combined ratio, the loss and loss expense ratio, the policy acquisition cost ratio, and the administrative expense ratio. We calculate these ratios by dividing the respective expense amounts by net premiums earned. We do not calculate these ratios for the Life segment as we do not use these measures to monitor or manage that segment. The combined ratio is determined by adding the loss and loss expense ratio, the policy acquisition cost ratio, and the administrative expense ratio. A combined ratio under 100 percent indicates underwriting income, and a combined ratio exceeding 100 percent indicates underwriting loss.

The following table presents our consolidated loss and loss expense ratio, policy acquisition cost ratio, administrative expense ratio, and combined ratio:

	Three Months Ended — June 30		Six Months Ended — June 30
	2014	2013	2014	2013
Loss and loss expense ratio	58.4 %	58.7 %	58.0 %	58.0 %
Policy acquisition cost ratio	16.6 %	15.9 %	17.1 %	16.5 %
Administrative expense ratio	12.7 %	13.3 %	13.1 %	13.6 %
Combined ratio	87.7 %	87.9 %	88.2 %	88.1 %

The following table presents the impact of catastrophe losses and related reinstatement premiums and the impact of prior period reserve development on our consolidated loss and loss expense ratio:

	Three Months Ended				Six Months Ended
	June 30				June 30
	2014		2013		2014		2013
Loss and loss expense ratio, as reported	58.4	%	58.7	%	58.0	%	58.0	%
Catastrophe losses and related reinstatement premiums	(2.1	)%	(2.3	)%	(1.8	)%	(1.7	)%
Prior period development	3.3	%	3.6	%	2.4	%	3.0	%
Loss and loss expense ratio, adjusted	59.6	%	60.0	%	58.6	%	59.3	%

Total net pre-tax catastrophe losses, excluding related reinstatement premiums, were $ 80 million and $133 million for the three and six months ended June 30, 2014 , compared with $81 million and $113 million in the prior year periods, respectively. Catastrophe losses through June 30, 2014 were primarily related to severe weather-related events in the U.S., Japan, and Australia, and flooding and hailstorms in Europe. Catastrophe losses in the prior year periods were primarily related to flooding in Canada and Australia and severe storms in the U.S. The adjusted loss and loss expense ratio decreased for the three and six months ended June 30, 2014 primarily due to both mix of business and underwriting actions improving loss ratios on several portfolios.

Prior period development arises from changes to loss estimates recognized in the current year that relate to loss events that occurred in previous calendar years and excludes the effect of losses from the development of earned premium from previous accident years. We experienced net favorable prior period development of $ 126 million and $188 million for the three and six months ended June 30, 2014 , respectively. This compares with net favorable prior period development of $128 million and $198 million in the prior year periods, respectively. Refer to “Prior Period Development” for additional information.

Net investment income for the three and six months ended June 30, 2014 was $556 million and $1.1 billion compared with $534 million and $1.1 billion for the prior year periods, respectively. Refer to “Net Investment Income” and “Investments” for additional information.

Policy acquisition costs consist of commissions, premium taxes, and certain underwriting costs related directly to the successful acquisition of a new or renewal insurance contract. Our policy acquisition cost ratio increased for the three and six months ended June 30, 2014 primarily due to a change in the mix of business to products and regions that have a higher acquisition ratio.

*Table of Contents*

Our administrative expense ratio decreased for the three months ended June 30, 2014 primarily due to growth in net premiums earned that outpaced the growth in administrative expenses, and the impact of the acquisitions described above, which include lower administrative expenses than our other businesses. In addition, the prior year included an expense adjustment that unfavorably impacted the prior year administrative expense ratio. A similar adjustment did not occur in the current year.

Our administrative expense ratio decreased for the six months ended June 30, 2014 primarily due to growth in net premiums earned that outpaced the growth in administrative expenses, and the impact of the acquisitions described above. In addition, the prior year included expense adjustments that unfavorably impacted the prior year administrative expense ratio, which were offset by the favorable impact of a prior year legal settlement.

Our effective income tax rate, which we calculate as income tax expense divided by income before income tax, is dependent upon the mix of earnings from different jurisdictions with various tax rates. A change in the geographic mix of earnings would change the effective income tax rate. Our effective income tax rate was 14.6 percent and 13.0 percent for the three and six months ended June 30, 2014 , respectively. Our effective income tax rate was 11.5 percent and 11.4 percent for the three and six months ended June 30, 2013 , respectively. The increase in effective tax rate was primarily due to both net realized losses and a lower percentage of operating earnings being generated in lower tax paying jurisdictions.

Prior Period Development

The following tables summarize (favorable) and adverse prior period development (PPD) by segment. Long-tail lines include lines such as workers' compensation, general liability, and professional liability; while short-tail lines include lines such as most property lines, energy, personal accident, aviation, marine (including associated liability-related exposures) and agriculture. Significant prior period movements by segment, principally driven by reserve reviews completed during each respective period, are discussed in more detail below. The remaining net development for long-tail and short-tail business for each segment comprises numerous favorable and adverse movements across a number of lines and accident years, none of which is significant individually or in the aggregate.

Insurance – North American P&C

2014

For the three months ended June 30, 2014 , net favorable PPD was $39 million, which was the net result of several underlying favorable and adverse movements, driven by the following principal changes:

• Net favorable development of $19 million in long-tail business, primarily from:

• Net favorable development of $33 million in our workers' compensation lines primarily in the 2013 accident year related to our annual assessment of multi-claimant events including industrial accidents. Consistent with prior years, we reviewed these potential exposures after the close of the accident year to allow for late reporting or identification of significant losses;

• Net favorable development of $21 million in our auto liability excess lines primarily impacting the 2009 accident year. Reported activity on loss and allocated loss expenses was lower than expected based on estimates from our prior review and original pricing assumptions; and

• Net adverse development of $28 million in our Brandywine run-off portfolios, primarily in general and products liability lines, including unallocated loss adjustment expenses, impacting the 1996 and prior accident years. Loss activity was higher than expected in these portfolios.

• Net favorable development of $20 million in short-tail business, with the notable driver being net favorable development of $14 million on wholesale property, primarily impacting the 2012 and 2013 accident years. Paid and reported loss activity was favorable relative to prior expectations, especially in our primary business, and in the development of losses arising from natural catastrophes.

For the six months ended June 30, 2014 , net favorable PPD was $107 million, which was the net result of several underlying favorable and adverse movements, driven by the following principal changes:

• Net favorable development of $80 million in long-tail business, primarily from:

• Favorable development of $67 million in our excess casualty and umbrella businesses. Resolution of a disputed matter on an individual claim led to a release of $42 million in the 2003 accident year, and lower than expected reported activity across a number of years drove the remaining improvement;

• Favorable development of $26 million in our surety business, primarily from favorable claim emergence in the 2012 accident year;

*Table of Contents*

• Net favorable development of $21 million in our auto liability excess lines primarily impacting the 2009 accident year due to the same factors experienced for the three months ended June 30, 2014 as described above; and

• Net adverse development of $36 million in our Brandywine run-off portfolios, primarily in general and products liability lines, including unallocated loss adjustment expenses, impacting the 1996 and prior accident years due to the same factors experienced for the three months ended June 30, 2014 as described above.

• Net favorable development of $27 million in short-tail business driven by net favorable development of $14 million on wholesale property, primarily impacting the 2012 and 2013 accident years, due to the same factors experienced for the three months ended June 30, 2014 as described above.

2013

For the three months ended June 30, 2013 , net favorable PPD was $47 million, which was the net result of several underlying favorable and adverse movements, driven by the following principal changes:

• Net favorable development of $19 million in long-tail business, primarily from:

• Net favorable development of $28 million in our national accounts portfolios which consist of commercial auto, general liability and workers' compensation lines of business. This favorable movement was the net impact of favorable and adverse movements, including:

• Favorable development of $40 million related to our annual assessment of multi-claimant events including industrial accidents impacting the 2012 accident year. Consistent with prior years, we reviewed these potential exposures after the close of the accident year to allow for late reporting or identification of significant losses;

• Net favorable development of $28 million on excess and high deductible workers' compensation lines driven by lower levels of reported losses than anticipated in our prior review and original pricing assumptions; and

• Adverse development of $40 million predominantly in workers' compensation related product lines primarily impacting the 2006 and prior accident years. The development was a function of higher than expected reported loss activity, higher allocated loss adjustment expenses, as well as increased weighting applied to experience-based methods.

• Net adverse development of $24 million in our Brandywine run-off portfolios primarily in general liability and workers' compensation product lines, including unallocated loss adjustment expenses, impacting the 1996 and prior accident years. Loss activity was higher than expected in these portfolios.

• Net favorable development of $28 million in short-tail business, which was the net result of several underlying favorable and adverse movements, none of which was significant individually or in the aggregate.

For the six months ended June 30, 2013 , net favorable PPD was $87 million, which was the net result of several underlying favorable and adverse movements, driven by the following principal changes:

• Net favorable development of $48 million in long-tail business, primarily from:

• Favorable development of $50 million in our U.S. excess casualty and umbrella businesses primarily impacting the 2007 and prior accident years. Reported activity on loss and allocated loss expenses was lower than expected based on estimates from our prior review. In addition, increased weighting was applied to experience-based methods;

• Net favorable development of $28 million in our national accounts portfolios, which consist of commercial auto, general liability and workers' compensation lines of business, due to the same factors experienced for the three months ended June 30, 2013 as described above.

• Net adverse development of $24 million in our Brandywine run-off portfolios' general liability and workers' compensation product lines, including unallocated loss adjustment expenses, impacting the 1996 and prior accident years due to the same factors experienced for the three months ended June 30, 2013 as described above.

*Table of Contents*

• Favorable development of $22 million in our surety business primarily impacting the 2011 accident year. Reported claims to date in the 2011 accident year were lower than historical averages which in turn has generated lower than expected reported loss activity; and

• Adverse development of $23 million in our construction business impacting the 2012 and prior accident years. The adverse development was realized in both our workers' compensation and general liability product lines where loss activity in the period since our prior review was higher than expected.

• Net favorable development of $39 million in short-tail business, which was the net result of several underlying favorable and adverse movements, none of which was significant individually or in the aggregate.

Insurance – North American Agriculture

Insurance – North American Agriculture experienced no PPD in both the three months ended June 30, 2014 and 2013.

For the six months ended June 30, 2014, adverse PPD was $38 million compared with favorable PPD of $3 million for the prior year period. Actual claim development in the first quarter of 2014 for the Multiple Peril Crop Insurance (MPCI) business was higher than our year-end 2013 expectations for the 2013 crop year.

Insurance – Overseas General

2014

For the three months ended June 30, 2014 net favorable PPD was $63 million which was the net result of several underlying favorable and adverse movements, driven by the following principal change:

• Favorable development of $66 million in short-tail business, primarily from the property (excluding technical lines) and marine lines. Favorable large loss experience in accident year 2013 led to a $36 million reduction. Favorable development on specific claims and additional credibility assigned to accident years 2012 and prior favorable indications led to a $28 million reduction.

For the six months ended June 30, 2014 net favorable PPD was $86 million due primarily to the same factors experienced for the three months ended June 30, 2014 as described above.

2013

For the three months ended June 30, 2013 net favorable PPD was $52 million, which was the net result of several underlying favorable and adverse movements, driven by the following principal change:

• Favorable development of $53 million in short-tail business, primarily from property and marine lines. Accident year 2009 through 2012 had favorable development of $38 million with no significant movement in any particular line or year. Accident years 2007 and prior had favorable development of $15 million mainly from specific litigated claims.

For the six months ended June 30, 2013 net favorable PPD was $74 million due to the same factors experienced for the three months ended June 30, 2013 as described above.

Global Reinsurance

2014

For the three and six months ended June 30, 2014 , net favorable PPD were $24 million and $33 million, respectively, which were the net result of several underlying favorable and adverse movements across a number of lines and across a number of treaty years, none of which was significant individually or in the aggregate.

2013

For the three months ended June 30, 2013 , net favorable PPD was $29 million which was the net result of several underlying favorable and adverse movements, driven by the following principal changes:

• Favorable development of $27 million in long-tail business, primarily in the casualty line of business principally in treaty years 2007 and prior and in the professional liability line of business principally in treaty years 2008 and prior. Following the reserve studies completed in the three months ended June 30, 2013, we increased weighting applied to experience-

based methods. Since experience has tended to be generally favorable compared with assumptions, the changes resulted in the favorable development referenced above.

For the six months ended June 30, 2013 , net favorable PPD was $34 million, which was the net result of several underlying favorable and adverse movements, primarily due to the same factors experienced for the three months ended June 30, 2013 as described above.

Net premiums written increased for the three and six months ended June 30, 2014 in our retail division from growth across a broad range of our product portfolio including our risk management business, surety, professional, general and specialty casualty, and A&H lines of business reflecting higher production and strong renewal retention. In addition, we grew net premiums written for the three and six months ended June 30, 2014 in our Commercial Risk Services division, primarily specialty and program business, and our personal lines division, primarily in the homeowners and automobile business offered through ACE Private Risk Services. Our wholesale and specialty divisions contributed to the increase in net premiums written for the three and six months ended June 30, 2014 from higher production in our property, casualty, and professional lines of business. In addition, net premiums written increased for the three and six months ended June 30, 2014 due to lower excess of loss premiums ceded under our 2014 catastrophe reinsurance program.

*Table of Contents*

Net premiums earned increased for the three and six months ended June 30, 2014 primarily due to the increase in net premiums written as described above.

The following tables present a line of business breakdown of Insurance – North American P&C net premiums earned:

The following table presents the impact of catastrophe losses and related reinstatement premiums and prior period reserve development on our loss and loss expense ratio:

	Three Months Ended				Six Months Ended
	June 30				June 30
	2014		2013		2014		2013
Loss and loss expense ratio, as reported	66.0	%	66.6	%	64.6	%	66.1	%
Catastrophe losses and related reinstatement premiums	(2.4	)%	(3.5	)%	(2.3	)%	(2.2	)%

Loss and loss expense ratio, adjusted	66.2	%	66.5	%	65.9	%	67.1	%

Net pre-tax catastrophe losses, excluding reinstatement premiums, were $36 million and $68 million for the three and six months ended June 30, 2014 , compared with $50 million and $61 million in the prior year periods, respectively. Catastrophe losses through June 30, 2014 were primarily from severe weather-related events in the U.S. and Australia. Catastrophe losses through June 30, 2013 were primarily from flooding in Canada and severe weather-related events in the U.S. Net favorable prior period development was $ 39 million and $107 million for the three and six months ended June 30, 2014 , compared with $ 47 million and $87 million in the prior year periods, respectively. Refer to “Prior Period Development” for additional information. For the three and six months ended June 30, 2014, the adjusted loss and loss expense ratio declined due to lower loss ratios in several of our lines where a combination of the execution of detailed portfolio management plans, product mix and earned rate changes have resulted in improved current accident year loss ratio performance. The improvement also reflects a reduction in loss adjustment expenses due to a change in estimated claim handling costs. These reductions were partially offset by higher non-catastrophe large losses in the current year quarter.

The policy acquisition cost ratio decreased slightly for the quarter and remained flat for the six months ended June 30, 2014 .

The administrative expense ratio was higher for the three months ended June 30, 2014 due primarily to a non-recurring expense adjustment which unfavorably impacted the current year ratio. Excluding this adjustment, the administrative expense ratio decreased by 0.1 points. For the six months ended June 30, 2014, the administrative expense ratio was higher compared to the prior year ratio which included a 1.0 point favorable impact related to a $29 million legal settlement. Excluding the impact of the legal settlement and the second quarter expense adjustment, the administrative expense ratio decreased for the six-month period by 0.4 points due to growth in net premiums earned that outpaced the growth in administrative expenses.

Refer to Note 7 and Note 10 to the consolidated financial statements for more information on these derivatives.

Net premiums written decreased for the three months ended June 30, 2014 principally due to lower MPCI production reflecting lower commodity prices partially offset by higher premium retention primarily as a result of the non-renewal of a third-party proportional reinsurance agreement. For the six months ended June 30, 2014, net premiums written increased as the decrease for the quarter was more than offset by lower premium cessions to the U.S. government for the 2013 crop year as a result of the government's crop insurance profit and loss calculation formula, which typically results in higher retained premiums when losses increase.

Net premiums earned decreased for the three months ended June 30, 2014 and increased for the six months ended June 30, 2014 primarily due to the factors described above.

The following table presents the impact of catastrophe losses and related reinstatement premiums and prior period reserve development on our loss and loss expense ratio:

	Three Months Ended				Six Months Ended
	June 30				June 30
	2014		2013		2014		2013
Loss and loss expense ratio, as reported	84.4	%	83.4	%	93.9	%	80.6	%

*Table of Contents*

Net pre-tax catastrophe losses, excluding reinstatement premiums, were $ 9 million and $10 million for the three and six months ended June 30, 2014 and $3 million for both of the prior year periods, respectively. For the three and six months ended June 30, 2014 , net unfavorable prior period development was nil and $38 million, respectively. For the six month period, the amount includes an increase in incurred losses of $39 million for higher than expected MPCI losses for the 2013 crop year, as well as $36 million of unfavorable MPCI losses offset by a favorable increase in net premiums earned related to the government's crop insurance profit and loss calculation formula. For the three and six months ended June 30, 2013, net favorable prior period development was nil and $3 million, respectively. Refer to “Prior Period Development” for additional information. The adjusted loss and loss expense ratio was lower for the three months ended June 30, 2014 due to the net impact of a decline in commodity prices that resulted in higher estimated losses on our crop policies that was more than offset by a decrease in losses from the fair value changes on our crop derivative. Despite the reduction in the adjusted loss and loss expense ratio for the three month period, the ratio for the six months ended June 30, 2014 increased reflecting lower loss adjustment expenses in the prior year period due to a change in estimated claim handling costs. A similar benefit did not occur in the current year.

The policy acquisition cost ratio increased for the three and six months ended June 30, 2014 primarily from lower ceded commission benefits on third-party reinsurance. For the six months ended June 30, 2014 , lower agent profit commission accruals for the 2013 crop year partially offset this increase.

The administrative expense ratio decreased for the three and six months ended June 30, 2014 due to lower expenses incurred.

(1) For the three and six months ended June 30, 2014, net premiums written increased $143 million or 8.8% on a constant-dollar basis and $337 million or 10.5% on a constant-dollar basis, respectively. Amounts are calculated by translating prior period results using the same local currency rates as the comparable current period.

Net premiums written increased for the three and six months ended June 30, 2014 on a constant-dollar basis from new business writings in our retail operations in all product lines – A&H, personal lines, and P&C. A&H growth was driven by strong

*Table of Contents*

results in all regions except Europe, and the increase in personal lines reflected growth in all regions, except Japan. P&C growth was driven primarily by new business writings in Asia and Europe and the acquisitions of ABA Seguros in May 2013 and Samaggi in April 2014. Growth for the six months ended June 30, 2014 also included the impact of Fianzas Monterrey, acquired in April 2013. The impact of foreign exchange adversely impacted growth in both periods on an as reported basis.

Net premiums earned increased for the three and six months ended June 30, 2014 primarily due to the increase in net premiums written as described above.

Net pre-tax catastrophe losses, excluding reinstatement premiums, were $26 million and $43 million for the three and six months ended June 30, 2014 , compared with $17 million and $38 million in the prior year periods, respectively. Catastrophe losses through June 30, 2014 were primarily related to flooding in Europe and severe storms in Japan. Catastrophe losses through June 30, 2013 were primarily related to flooding in Australia and Canada. Net favorable prior period development was $63 million and $86 million for the three and six months ended June 30, 2014 , compared with $52 million and $74 million in the prior year periods, respectively. Refer to “Prior Period Development” for additional information. The decrease in the adjusted loss and loss expense ratio for the three and six months ended June 30, 2014 was due primarily to both mix of business and underwriting actions improving loss ratios on several portfolios.

The policy acquisition cost ratio increased for the three months ended June 30, 2014 primarily due to a change in the overall mix of business towards A&H and personal lines products in regions that have higher acquisition cost ratios. For the six months ended June 30, 2014, the increase noted above was partially offset by the impact of the businesses acquired described above, which carry lower acquisition cost ratios than our other businesses, and the result of purchase accounting requirements. As a result of purchase accounting requirements, the unearned premiums at the date of purchase related to the businesses acquired are recognized over the remaining coverage period with no expense for the associated historical acquisition costs that were incurred to underwrite those policies.

The administrative expense ratio decreased for the three and six months ended June 30, 2014 due primarily to growth in net premiums earned that outpaced the growth in administrative expenses, and the acquisitions described above, which include lower administrative expenses than our other businesses.

Net premiums written decreased for the three months ended June 30, 2014 primarily due to lower net property catastrophe premiums. For the six months ended June 30, 2014 , this decrease was more than offset by increased net premiums written from a number of new large personal lines structured transactions (homeowners and automobile) in our U.S. operations.

Net premiums earned increased for the three and six months ended June 30, 2014 primarily in our U.S. property and casualty lines of business from higher premiums written in the current and prior year periods.

Net pre-tax catastrophe losses, excluding reinstatement premiums, were $9 million and $12 million for the three and six months ended June 30, 2014 and $11 million for both of the prior year periods, respectively. Catastrophe losses through June 30, 2014 were related to severe storms in Japa n, European hailstorms and severe weather related events in the U.S. Catastrophe losses through June 30, 2013 were primarily related to flooding in Canada and Europe. Net favorable prior period development was $24 million and $33 million for the three and six months ended June 30, 2014 , compared with $29 million and $34 million in the prior year periods, respectively. Refer to “Prior Period Development” for additional information. The adjusted loss and loss expense ratio increased for the three and six months ended June 30, 2014 primarily due to a change in the mix of business towards higher loss ratio products.

The policy acquisition cost ratio increased for the three and six months ended June 30, 2014 primarily due to a change in the mix of business towards products written in the U.S. that have a higher acquisition cost ratio than in other regions.

The administrative expense ratio increased for the three and six months ended June 30, 2014 . The prior year included the favorable impact of a $2 million expense adjustment that reduced the administrative expense ratio in the prior year periods. Excluding this adjustment, the administrative expense ratio decreased for the three and six months ended June 30, 2014 due to the increase in net premiums earned.

Life

The Life segment includes our international life operations (ACE Life), ACE Tempest Life Re (ACE Life Re), and the North American supplemental A&H and life business of Combined Insurance. We assess the performance of our life business based on Life underwriting income, which includes Net investment income and (Gains) losses from fair value changes in separate account assets that do not qualify for separate account reporting under GAAP.

The following table presents a line of business breakdown of Life net premiums written and deposits collected on universal life and investment contracts:

	Three Months Ended — June 30		% Change		Six Months Ended — June 30		% Change
(in millions of U.S. dollars, except for percentages)	2014	2013	Q-14 vs. Q-13		2014	2013	YTD-14 vs. YTD-13
A&H	$ 247	$ 252	(2.0	)%	$ 494	$ 513	(3.7	)%
Life insurance	186	163	14.1	%	366	330	10.9	%
Life reinsurance	65	72	(9.7	)%	132	146	(9.6	)%
Net premiums written (excludes deposits below)	$ 498	$ 487	2.2	%	$ 992	$ 989	0.2	%
Deposits collected on universal life and investment contracts	$ 282	$ 222	27.0	%	$ 484	$ 424	14.2	%

A&H net premiums written decreased for the three and six months ended June 30, 2014 as growth in certain program business was more than offset by the non-renewal of several large accounts and a catch-up in premium registrations in the prior year periods. Life insurance net premiums written increased for the three and six months ended June 30, 2014 primarily due to growth in our Asian and Latin American markets. Life reinsurance net premiums written decreased for the three and six months ended June 30, 2014 because no new life reinsurance business is currently being written.

Deposits collected on universal life and investment contracts (life deposits) are not reflected as revenues in our consolidated statements of operations in accordance with GAAP. New life deposits are an important component of production and key to our efforts to grow our business. Although life deposits do not significantly affect current period income from operations, they are an

*Table of Contents*

important indicator of future profitability. Life deposits collected for the three and six months ended June 30, 2014 increased compared to prior year due to growth in our Asian markets.

Net realized gains (losses), which are excluded from Life underwriting income, relate primarily to the change in the net fair value of reported GLB reinsurance liabilities and changes in the fair value of derivatives used to partially offset the risk in the variable annuity guarantee portfolio. During the quarter, realized gains of $2 million were associated with a net decrease in the value of GLB liabilities. During the six months ended June 30, 2014, realized losses of $48 million were associated with a net increase in the value of GLB liabilities. The increase in the value of GLB liabilities during the six months ended June 30, 2014, was primarily due to lower interest rates and the unfavorable impact of discounting future claims for two fewer quarters, partially offset by rising U.S. equity levels. In addition, we experienced realized losses of $72 million and $91 million for the three and six months ended June 30, 2014 due to a decrease in the value of the derivative instruments, which decrease in value when the S&P 500 index increases.

Other (income) expense includes Amortization of intangible assets, which is higher in 2014 due primarily to our recent acquisitions. Refer to Note 2 to the Consolidated Financial Statements for additional information on our acquisitions. Equity in net (income) loss of partially-owned entities includes our share of net (income) loss related to investment funds, limited partnerships, partially-owned investment companies, and partially-owned insurance companies. Also included in Other (income) expense are (Gains) losses from fair value changes in separate account assets that do not qualify for separate account reporting under GAAP. The offsetting movement in the separate account liabilities is included in Policy benefits in the consolidated statements of operations. Certain federal excise and capital taxes incurred as a result of capital management initiatives are included in Other (income) expense as these are considered capital transactions and are excluded from underwriting results.

The following table presents, as of June 30, 2014 , the estimated pre-tax amortization expense related to intangible assets for the third and fourth quarters of 2014 and the next five years:

Net investment income	$ 556		$ 534		$ 1,109		$ 1,065

Net investment income is influenced by a number of factors including the amounts and timing of inward and outward cash flows, the level of interest rates, and changes in overall asset allocation. Net investment income increased 4.2 percent and 4.1 percent for the three and six months ended June 30, 2014 , respectively, compared with the prior year periods. The increase in net investment income was primarily due to a higher invested asset base.

The investment portfolio’s average market yield on fixed maturities was 2.6 percent and 2.9 percent at June 30, 2014 and 2013 , respectively. Average market yield on fixed maturities represents the weighted average yield to maturity of our fixed income portfolio based on the market prices of the holdings at that date.

The 1.8 percent and 1.7 percent yield on short-term investments for the three and six months ended June 30, 2014 , respectively, reflect the global nature of our insurance operations. For example, yields on short-term investments in Mexico, Malaysia, Indonesia, China, and Ecuador range from 3.0 percent to 8.2 percent .

The 4.4 percent yield on our equity securities portfolio is high relative to the yield on the S&P 500 Index because of dividends on preferred equity securities and because we classify our strategic emerging debt portfolio, which is a mutual fund, as equity. The preferred equity securities and strategic emerging debt portfolio represented 68 percent and 70 percent of the gross equity securities investment income for the three and six months ended June 30, 2014 , respectively.

Net Realized and Unrealized Gains (Losses)

We take a long-term view with our investment strategy, and our investment managers manage our investment portfolio to maximize total return within certain specific guidelines designed to minimize risk. The majority of our investment portfolio is available for sale and reported at fair value. Our held to maturity investment portfolio is reported at amortized cost.

The effect of market movements on our available for sale investment portfolio impacts Net income (through Net realized gains (losses)) when securities are sold or when we record an Other-than-temporary impairment (OTTI) charge in Net income. For a discussion related to how we assess OTTI for all of our investments, including credit-related OTTI, and the related impact on Net income, refer to Note 3 c) to the Consolidated Financial Statements. Additionally, Net income is impacted through the reporting of changes in the fair value of derivatives, including financial futures, options, swaps, and GLB reinsurance. Changes in unrealized appreciation and depreciation on available for sale securities, which result from the revaluation of securities held, are reported as a separate component of Accumulated other comprehensive income in Shareholders’ equity in the consolidated balance sheets.

*Table of Contents*

At June 30, 2014 , our investment portfolios held by U.S. legal entities included approximately $ 60 million of gross unrealized losses on fixed income investments. Our tax planning strategy related to these losses is based on our view that we will hold these fixed income investments until they recover their cost. As such, we have recognized a deferred tax asset of approximately $ 21 million related to these fixed income investments. This strategy allows us to recognize the associated deferred tax asset related to these fixed income investments as we do not believe these losses will ever be realized.

Investments

Our investment portfolio is invested primarily in publicly traded, investment grade, fixed income securities with an average credit quality of A/Aa as rated by the independent investment rating services Standard and Poor’s (S&P)/ Moody’s Investors Service (Moody’s). The portfolio is externally managed by independent, professional investment managers and is broadly diversified across geographies, sectors, and issuers. Other investments principally comprise direct investments, investment funds, and limited partnerships. We hold no collateralized debt obligations or collateralized loan obligations in our investment portfolio, and we provide no credit default protection. We have long-standing global credit limits for our entire portfolio across the organization. Exposures are aggregated, monitored, and actively managed by our Global Credit Committee, comprising senior executives, including our Chief Financial Officer, our Chief Risk Officer, our Chief Investment Officer, and our Treasurer. We also have well-established, strict contractual investment rules requiring managers to maintain highly diversified exposures to individual issuers and closely monitor investment manager compliance with portfolio guidelines.

The average duration of our fixed income securities, including the effect of options and swaps, was 4.0 years at both June 30, 2014 and December 31, 2013 . We estimate that a 100 basis point (bps) increase in interest rates would reduce the valuation of our fixed income portfolio by approximately $2.4 billion at June 30, 2014 .

The following table shows the fair value and cost/amortized cost of our invested assets:

(in millions of U.S. dollars)	June 30, 2014 — Fair Value	Cost/ Amortized Cost	December 31, 2013 — Fair Value	Cost/ Amortized Cost
Fixed maturities available for sale	$ 51,601	$ 49,719	$ 49,254	$ 48,406

Total investments	$ 63,861	$ 61,351	$ 61,093	$ 59,779

The fair value of our total investments increased $2.8 billion during the six months ended June 30, 2014 , primarily due to the investing of operating cash flows and unrealized appreciation.

Municipal

As part of our overall investment strategy, we may invest in states, municipalities, and other political subdivisions fixed maturity securities (Municipal). We apply the same investment selection process described previously to our Municipal investments. The portfolio is highly diversified primarily in state general obligation bonds and essential service revenue bonds including education and utilities (water, power, and sewers).

Non-U.S.

Our exposure to the Euro results primarily from ACE European Group which is headquartered in London and offers a broad range of coverages throughout the European Union, Central, and Eastern Europe. ACE primarily invests in Euro denominated investments to support its local currency insurance obligations and required capital levels. ACE’s local currency investment portfolios have strict contractual investment guidelines requiring managers to maintain a high quality and diversified portfolio to both sector and individual issuers. Investment portfolios are monitored daily to ensure investment manager compliance with portfolio guidelines.

Our non-U.S. investment grade fixed income portfolios are currency-matched with the insurance liabilities of our non-U.S. operations. The average credit quality of our non-U.S. fixed income securities is A and 52 percent of our holdings are rated AAA or guaranteed by governments or quasi-government agencies. Within the context of these investment portfolios, our government and corporate bond holdings are highly diversified across industries and geographies. Issuer limits are based on credit rating (AA— two percent, A— one percent, BBB— 0.5 percent of the total portfolio) and are monitored daily via an internal compliance system. Because of this investment approach we do not have a direct exposure to troubled sovereign borrowers in Europe. We manage our indirect exposure using the same credit rating based investment approach. Accordingly, we do not believe our indirect exposure is material.

The following table summarizes the market value and amortized cost of our non-U.S. fixed income portfolio by country/sovereign for non-U.S. government securities at June 30, 2014 :

The countries that are listed in the non-U.S. corporate fixed income portfolio above represent the ultimate parent company's country of risk. Non-U.S. corporate securities could be issued by foreign subsidiaries of U.S. corporations.

Below-investment grade corporate fixed income portfolio

Below-investment grade securities have different characteristics than investment grade corporate debt securities. Risk of loss from default by the borrower is greater with below-investment grade securities. Below-investment grade securities are generally unsecured and are often subordinated to other creditors of the issuer. Also, issuers of below-investment grade securities usually have higher levels of debt and are more sensitive to adverse economic conditions, such as recession or increasing interest rates, than are investment grade issuers. At June 30, 2014 , our corporate fixed income investment portfolio included below-investment grade and non-rated securities which, in total, comprised approximately 14 percent of our fixed income portfolio. Our below-investment grade and non-rated portfolio includes over 1,200 issuers, with the greatest single exposure being $97 million.

We manage high-yield bonds as a distinct and separate asset class from investment grade bonds. The allocation to high-yield bonds is explicitly set by internal management and is targeted to securities in the upper tier of credit quality (BB/B). Our minimum rating for initial purchase is BB/B. Six external investment managers are responsible for high-yield security selection and portfolio construction. Our high-yield managers have a conservative approach to credit selection and very low historical default experience. Holdings are highly diversified across industries and subject to a 1.5 percent issuer limit as a percentage of high-yield allocation. We monitor position limits daily through an internal compliance system. Derivative and structured securities (e.g., credit default swaps and collateralized loan obligations) are not permitted in the high-yield portfolio.

Critical Accounting Estimates

As of June 30, 2014 , there were no material changes to our critical accounting estimates. For a full discussion of our critical accounting estimates, refer to Item 7 in our 2013 Form 10-K.

Reinsurance recoverable on ceded reinsurance

	June 30	December 31
(in millions of U.S. dollars)	2014	2013
Reinsurance recoverable on unpaid losses and loss expenses (1)	$ 10,110	$ 10,612
Reinsurance recoverable on paid losses and loss expenses (1)	658	615
Net reinsurance recoverable on losses and loss expenses	$ 10,768	$ 11,227
Reinsurance recoverable on policy benefits	$ 234	$ 218

(1) Net of provision for uncollectible reinsurance

*Table of Contents*

We evaluate the financial condition of our reinsurers and potential reinsurers on a regular basis and also monitor concentrations of credit risk with reinsurers. The provision for uncollectible reinsurance is required principally due to the potential failure of reinsurers to indemnify us, primarily because of disputes under reinsurance contracts and insolvencies. The provision for uncollectible reinsurance is based on a default analysis applied to gross reinsurance recoverables, net of approximately $2.4 billion and $ 2.3 billion of collateral at June 30, 2014 and December 31, 2013 , respectively. The decrease in net reinsurance recoverable on losses and loss expenses was primarily due to favorable PPD, crop activity, and collections relating to run-off operations.

Unpaid losses and loss expenses

As an insurance and reinsurance company, we are required by applicable laws and regulations and GAAP to establish loss and loss expense reserves for the estimated unpaid portion of the ultimate liability for losses and loss expenses under the terms of our policies and agreements with our insured and reinsured customers. At June 30, 2014 , our gross unpaid loss and loss expense reserves were $37.2 billion and our net unpaid loss and loss expense reserves were $27.1 billion. With the exception of certain structured settlements, for which the timing and amount of future claim payments are reliably determinable, and certain reserves for unsettled claims that are discounted in statutory filings, our loss reserves are not discounted for the time value of money.

The following table presents a roll-forward of our unpaid losses and loss expenses:

(in millions of U.S. dollars) — Balance at December 31, 2013	Gross Losses — $ 37,443		Reinsurance Recoverable (1) — $ 10,612		Net Losses — $ 26,831
Losses and loss expenses incurred	5,466		917		4,549
Losses and loss expenses paid	(5,937	)	(1,491	)	(4,446	)
Other (including foreign exchange translation)	205		72		133
Balance at June 30, 2014	$ 37,177		$ 10,110		$ 27,067

(1) Net of provision for uncollectible reinsurance

The estimate of the liabilities includes provisions for claims that have been reported but are unpaid at the balance sheet date (case reserves) and for obligations on claims that have been incurred but not reported (IBNR) at the balance sheet date. IBNR may also include provisions to account for the possibility that reported claims may settle for amounts that differ from the established case reserves. Loss reserves also include an estimate of expenses associated with processing and settling unpaid claims (loss expenses).

The following table presents our total reserves segregated between case reserves (including loss expense reserves) and IBNR reserves:

(in millions of U.S. dollars)	June 30, 2014 — Gross	Ceded	Net	December 31, 2013 — Gross	Ceded	Net
Case reserves	$ 15,894	$ 4,377	$ 11,517	$ 16,558	$ 4,790	$ 11,768
IBNR reserves	21,283	5,733	15,550	20,885	5,822	15,063
Total	$ 37,177	$ 10,110	$ 27,067	$ 37,443	$ 10,612	$ 26,831

Asbestos and Environmental (A&E) and Other Run-off Liabilities

There was no significant A&E reserve activity during the six months ended June 30, 2014 . Refer to our 2013 Form 10-K for additional information on A&E and Other Run-off Liabilities.

Fair value measurements

Accounting guidance defines fair value as the price to sell an asset or transfer a liability (an exit price) in an orderly transaction between market participants and establishes a three-level valuation hierarchy based on the reliability of the inputs.

The fair value hierarchy gives the highest priority to quoted prices in active markets (Level 1 inputs) and the lowest priority to unobservable data (Level 3 inputs):

• Level 1 inputs are unadjusted quoted prices for identical assets or liabilities in active markets.

*Table of Contents*

• Level 2 includes inputs other than quoted prices included within Level 1 that are observable for assets or liabilities either directly or indirectly. Level 2 inputs include, among other items, quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, and inputs other than quoted prices that are observable for the asset or liability such as interest rates and yield curves.

• Level 3 inputs are unobservable and reflect our judgments about assumptions that market participants would use in pricing an asset or liability.

While we obtain values for the majority of our investment securities from pricing services, it is ultimately our responsibility to determine whether the values obtained in the financial statements are representative of fair value. We periodically update our understanding of the methodologies used by our pricing services in order to validate that the prices obtained from those services are consistent with the GAAP definition of fair value as an exit price. Based on our understanding of the methodologies, our pricing services only produce an estimate of fair value if there is observable market information that would allow them to make a fair value estimate. Based on our understanding of the market inputs used by our pricing services, all applicable investments have been valued in accordance with GAAP valuation principles. We have controls to review significant price changes and stale pricing, and to ensure that prices received from pricing services have been accurately reflected in the consolidated financial statements. We do not adjust prices obtained from pricing services.

Additionally, fixed maturities valuation is more subjective when markets are less liquid due to the lack of market based inputs (i.e., stale pricing), which may increase the potential that an investment's estimated fair value is not reflective of the price at which an actual transaction would occur. For a small number of fixed maturities, we obtain a quote from a broker (typically a market maker). Due to the disclaimers on the quotes that indicate that the price is indicative only, we include these fair value estimates in Level 3.

At both June 30, 2014 and December 31, 2013, Level 3 assets represented five percent of assets measured at fair value and three percent of total assets. Level 3 liabilities represented 90 percent and 74 percent of liabilities measured at fair value at June 30, 2014 and December 31, 2013, respectively, and less than one percent of our total liabilities at both June 30, 2014 and December 31, 2013. During the three and six months ended June 30, 2014 , we transferred assets of $ 28 million and $32 million into our Level 3 assets from other levels of the valuation hierarchy. During the three and six months ended June 30, 2014 , we transferred assets of $ 16 million and $65 million out of our Level 3 assets to other levels of the valuation hierarchy. Refer to Note 4 to the consolidated financial statements for a description of the valuation techniques and inputs used to determine fair values for our financial instruments measured or disclosed at fair value by valuation hierarchy (Levels 1, 2, and 3) as well as a roll-forward of Level 3 financial instruments measured at fair value for the three and six months ended June 30, 2014 and 2013 .

Guaranteed living benefits (GLB) derivatives

Under life reinsurance programs covering living benefit guarantees, we assumed the risk of GLBs associated with variable annuity (VA) contracts. We ceased writing this business in 2007. Our GLB reinsurance product meets the definition of a derivative for accounting purposes and is therefore carried at fair value. We believe that the most meaningful presentation of these derivatives is to reflect cash inflows or revenue as net premiums earned, and to record estimates of the average modeled value of future cash outflows as incurred losses. Accordingly, we recognize benefit reserves consistent with the accounting guidance related to accounting and reporting by insurance enterprises for certain non-traditional long-duration contracts and for separate accounts. Changes in the benefit reserves are reflected as Policy benefits expense, which is included in life underwriting income. The incremental difference between fair value and benefit reserves is reflected in Accounts payable, accrued expenses, and other liabilities in the consolidated balance sheets and related changes in fair value are reflected in Net realized gains (losses) in the consolidated statement of operations. We intend to hold these derivative contracts to maturity (i.e., the expiration of the underlying liabilities through lapse, annuitization, death, or expiration of the reinsurance contract). To partially offset the risk in the VA guarantee reinsurance portfolio, we invest in derivative hedge instruments. At maturity, the cumulative gains and losses will net to zero (excluding cumulative hedge gains or losses) because, over time, the insurance liability will be increased or decreased to equal our obligation. For a sensitivity discussion of the effect of changes in interest

*Table of Contents*

rates, equity indices, and other assumptions on the fair value of GLBs, and the resulting impact on our net income, refer to Item 3.

The fair value of GLB reinsurance is estimated using an internal valuation model, which includes current market information and estimates of policyholder behavior from the perspective of a theoretical market participant that would assume these liabilities. All of our treaties contain claim limits, which are factored into the valuation model. The fair value depends on a number of factors, including interest rates, current account value, market volatility, expected annuitization rates and other policyholder behavior, and changes in policyholder mortality. The model and related assumptions are continuously re-evaluated by management and enhanced, as appropriate, based upon additional experience obtained related to policyholder behavior and availability of more timely market information, such as market conditions and demographics of in-force annuities. Due to the inherent uncertainties of the assumptions used in the valuation models to determine the fair value of these derivative products, actual experience may differ from the estimates reflected in our consolidated financial statements, and the differences may be material. For further information on the estimates and assumptions used in determining the fair value of GLB reinsurance, refer to Note 4 to the Consolidated Financial Statements of our 2013 Form 10-K.

ACE Tempest Life Re employs a strategy to manage the financial market and policyholder behavior risks embedded in the reinsurance of VA guarantees. Risk management begins with underwriting a prospective client and guarantee design, with particular focus on protecting our position from policyholder options that, because of anti-selective behavior, could adversely impact our obligation.

A second layer of risk management is the structure of the reinsurance contracts. All VA guarantee reinsurance contracts include some form of annual or aggregate claim limit(s) that would reduce our obligation. For further information on the different categories of claim limits, refer to "Guaranteed living benefits derivatives" in our 2013 Form 10-K under Item 7.

A third layer of risk management is the hedging strategy which looks to mitigate both long-term economic loss over time as well as dampen income statement volatility. ACE Tempest Life Re owned financial market instruments as part of the hedging strategy with a fair value liability of $ 13 million and $54 million at June 30, 2014 and December 31, 2013 , respectively. The instruments are substantially collateralized by our counterparties, on a daily basis.

We also limit the aggregate amount of variable annuity reinsurance guarantee risk we are willing to assume. The last substantive U.S. transaction was quoted in mid-2007 and the last transaction in Japan was quoted in late 2007. The aggregate number of policyholders is currently decreasing at a rate of 7 percent – 15 percent per annum due to policyholder lapses, annuitizations, and deaths.

Note that GLB claims cannot occur for any reinsured policy until it has reached the end of its “waiting period”. The majority of policies we reinsure reach the end of their “waiting periods” in 2014 or later, as shown in the table below.

Year of first payment eligibility	Percent of living benefit account values

Death Benefits (GMDB)

For premiums and claims from VA contracts reinsuring GMDBs, at current market levels, we expect approximately $ 40 million of claims and $ 66 million of premium on death benefits over the next 12 months.

GLB (includes GMIB and GMAB)

Our GLBs predominantly include premiums and claims from VA contracts reinsuring GMIB and GMAB. More than 60 percent of our living benefit reinsurance clients’ policyholders, measured by account value, are currently ineligible to trigger a claim payment. At current market levels, we expect approximately $5 million of claims and $132 million of premium on living benefits over the next 12 months.

Collateral

ACE Tempest Life Re holds collateral on behalf of most of its clients in the form of qualified assets in trust or letters of credit, typically in an amount sufficient for the client to obtain statutory reserve credit for the reinsurance. The timing of the calculation and amount of the collateral varies by client according to the particulars of the reinsurance treaty and the statutory reserve guidelines of the client’s domicile.

Catastrophe management

We actively monitor our catastrophe risk accumulation around the world. The table below presents our modeled annual aggregate pre-tax probable maximum loss (PML), net of reinsurance, for 100-year and 250-year return periods for a U.S. hurricane and a California earthquake at June 30, 2014 and 2013 . The table also presents ACE’s corresponding share of pre-tax industry losses for each of the return periods for a U.S. hurricane and a California earthquake. For example, according to the model, for the 1-in-100 return period scenario, there is a one percent chance that our losses incurred in any year from a U.S. hurricane could be in excess of $1,745 million (or 5.8 percent of our total shareholders’ equity at June 30, 2014 ). We estimate that at such hypothetical loss levels, ACE’s share of aggregate industry losses would be approximately 1.1 percent.

	U.S. Hurricane	June 30		June 30	California Earthquake	June 30		June 30
		2014		2013		2014		2013
Modeled Annual Aggregate Net PML	ACE	% of Total Shareholders’ Equity	% of Industry	ACE	ACE	% of Total Shareholders’ Equity	% of Industry	ACE
(in millions of U.S. dollars, except for percentages)
1-in-100	$ 1,745	5.8 %	1.1 %	$ 1,714	$ 778	2.6 %	1.9 %	$ 802
1-in-250	$ 2,335	7.7 %	1.0 %	$ 2,263	$ 1,020	3.4 %	1.6 %	$ 1,005

The above modeled loss information reflects our in-force portfolio as of April 1, 2014 and reinsurance program effective at July 1, 2014. Effective July 1, 2014, ACE established a new Global Property Catastrophe Program for our North American and International operations that provided global natural catastrophe and terrorism coverage. Refer to "Natural catastrophe property reinsurance program" for additional information.

The modeling estimates of both ACE and industry loss levels are inherently uncertain owing to key assumptions. First, while the use of third-party catastrophe modeling packages to simulate potential hurricane and earthquake losses is prevalent within the insurance industry, the models are reliant upon significant meteorology, seismology, and engineering assumptions to estimate hurricane and earthquake losses. In particular, modeled hurricane and earthquake events are not always a representation of actual events and ensuing additional loss potential. Second, there is no universal standard in the preparation of insured data for use in the models and the running of the modeling software. Third, we are reliant upon third-party estimates of industry insured exposures and there is significant variation possible around the relationship between our loss and that of the industry following an event. Fourth, we assume that our reinsurance recoveries following an event are fully collectible. These loss estimates do not represent our potential maximum exposures and it is highly likely that our actual incurred losses would vary materially from the modeled estimates.

Natural catastrophe property reinsurance program

ACE’s core property catastrophe reinsurance program provides protection against natural catastrophes impacting its primary property operations (i.e., excluding our Global Reinsurance and Life segments).

We regularly review our reinsurance protection and corresponding property catastrophe exposures. This may or may not lead to the purchase of additional reinsurance prior to a program’s renewal date. In addition, prior to each renewal date, we consider how much, if any, coverage we intend to buy and we may make material changes to the current structure in light of various factors, including modeled PML assessment at various return periods, reinsurance pricing, our risk tolerance and exposures, and various other structuring considerations.

ACE established a new Global Catastrophe Program for our North American and International operations. The program is effective July 1, 2014 through June 30, 2015, and consists of two layers in excess of losses retained by ACE. Approximately 20 percent of the coverage was placed with reinsurers providing upfront collateral equal to the limit of their participation and without a reinstatement. The remaining coverage was placed without upfront collateral and with one additional reinstatement limit in the event of a natural peril loss. In addition, we also purchased terrorism coverage (excluding nuclear, biological, chemical and radiation coverage) for the United States from July 1, 2014 to June 30, 2015 with the same limits and retention

*Table of Contents*

and percentage placed except that the majority of terrorism coverage is on an aggregate basis above our retentions without a reinstatement.

Crop Insurance

We are, and have been since the 1980s, one of the leading writers of crop insurance in the U.S. and have conducted that business through a managing general agent subsidiary of Rain and Hail. We provide protection throughout the U.S. on a variety of crops and are therefore geographically diversified, which reduces the risk of exposure to a single event or a heavy accumulation of losses in any one region. Our crop insurance business comprises two components – Multiple Peril Crop Insurance (MPCI) and crop-hail insurance.

The MPCI program is offered in conjunction with the U.S. Department of Agriculture (USDA). The policies cover revenue shortfalls or production losses due to natural causes such as drought, excessive moisture, hail, wind, frost, insects, and disease. Generally, policies have deductibles ranging from 10 percent to 50 percent of the insured's risk. The USDA's Risk Management Agency (RMA) sets the policy terms and conditions, rates and forms, and is also responsible for setting compliance standards. As a participating company, we report all details of policies underwritten to the RMA and are party to a Standard Reinsurance Agreement (SRA). The SRA sets out the relationship between private insurance companies and the Federal Crop Insurance Corporation (FCIC) concerning the terms and conditions regarding the risks each will bear including the pro-rata and state stop-loss provisions which allows companies to limit the exposure of any one state or group of states on their underwriting results. In addition to the pro-rata and excess of loss reinsurance protections inherent in the SRA, we also purchase third-party proportional and stop-loss reinsurance for our MPCI business to reduce our exposure. From time to time we may also enter into crop derivative contracts to further manage our risk exposure.

Each year the RMA issues a final SRA for the subsequent reinsurance year. In June 2014, the RMA released the 2015 SRA which establishes the terms and conditions for the 2015 reinsurance year (i.e., July 1, 2014 through June 30, 2015) that replaced the 2014 SRA. There were no significant changes in the terms and conditions.

On the MPCI business, we recognize net premiums written as soon as estimable, which is generally when we receive acreage reports from the policyholders on the various crops throughout the U.S. This allows us to best determine the premium associated with the liability that is being planted. The MPCI program has specific timeframes as to when producers must report acreage to us and in certain cases, the reporting occurs after the close of the respective reinsurance year. Once the net premium written has been recorded, the premium is then earned over the growing season for the crops. A majority of the crops

*Table of Contents*

that are covered in the program are typically subject to the SRA in effect at the beginning of the year. Given the major crops covered in the program, we typically see a substantial written and earned premium impact in the second and third quarters.

The pricing of MPCI premium is determined using a number of factors including commodity prices and related volatility. For instance, in most states the pricing for the MPCI Revenue Product for corn includes a factor that is based on the average price in February of the Chicago Board of Trade December corn futures. To the extent that the corn commodity prices are higher in February than they were in the previous February, and all other factors are the same, the increase in corn prices will increase the corn premium year over year.

Our crop-hail program is a private offering. Premium is earned on the crop-hail program over the coverage period of the policy. Given the very short nature of the growing season, most crop-hail business is typically written in the second and third quarters with the earned premium also more heavily occurring during this time frame. We use industry data to develop our own rates and forms for the coverage offered. The policy primarily protects farmers against yield reduction caused by hail and/or fire, and related costs such as transit to storage. We offer various deductibles to allow the grower to partially self-insure for a reduced premium cost. We limit our crop-hail exposures through the use of township liability limits and third-party proportional and stop-loss reinsurance on our net retained hail business.

Liquidity

We anticipate that positive cash flows from operations (underwriting activities and investment income) should be sufficient to cover cash outflows under most loss scenarios for the near term. In addition to cash from operations, routine sales of investments, and financing arrangements, we have agreements with a third-party bank provider which implemented two international multi-currency notional cash pooling programs to enhance cash management efficiency during periods of short-term timing mismatches between expected inflows and outflows of cash by currency. The programs allow us to optimize investment income by avoiding portfolio disruption. Should the need arise, we generally have access to capital markets and available credit facilities. At June 30, 2014 , our available credit lines totaled $1.4 billion and usage of these credit lines was $648 million . Our access to funds under existing credit facilities is dependent on the ability of the banks that are parties to the faci lities to meet their funding commitments. Our existing credit facilities have remaining terms expiring between November 2017 and December 2017 and require that we maintain certain financial covenants, all of which we met at June 30, 2014 . We did not renew our $500 million bilateral letter of credit facility that expired in June 2014. We elected instead to satisfy our collateral obligations primarily with insurance trusts supported by our investment portfolio. Should any of our existing credit providers experience financial difficulty, we may be required to replace credit sources, possibly in a difficult market. If we cannot obtain adequate capital or sources of credit on favorable terms, on a timely basis, or at all, our business, operating results, and financial condition could be adversely affected. To date, we have not experienced difficulty accessing any of our credit facilities . Refer to “Credit Facilities” in our 2013 Form 10-K for additional information.

The payment of dividends or other statutorily permissible distributions from our operating companies are subject to the laws and regulations applicable to each jurisdiction as well as the need to maintain capital levels adequate to support the insurance and reinsurance operations, including financial strength ratings issued by independent rating agencies. During the six months ended June 30, 2014 , we were able to meet all of our obligations, including the payments of dividends on our Common Shares, with our net cash flows.

We assess which subsidiaries to draw dividends from based on a number of factors. Considerations such as regulatory and legal restrictions as well as the subsidiary’s financial condition are paramount to the dividend decision. ACE Limited received no dividends from its Bermuda subsidiaries during the six months ended June 30, 2014 and 2013 .

The payment of any dividends from AGM or its subsidiaries is subject to applicable U.K. insurance laws and regulations. In addition, the release of funds by Syndicate 2488 to subsidiaries of AGM is subject to regulations promulgated by the Society of Lloyd’s. The U.S. insurance subsidiaries of ACE INA may pay dividends, without prior regulatory approval, subject to restrictions set out in state law of the subsidiary’s domicile (or, if applicable, commercial domicile). ACE INA’s international subsidiaries are also subject to insurance laws and regulations particular to the countries in which the subsidiaries operate. These laws and regulations sometimes include restrictions that limit the amount of dividends payable without prior approval of regulatory insurance authorities. ACE Limited received no dividends from AGM or ACE INA during the six months ended June 30, 2014 and 2013 . Debt issued by ACE INA is serviced by statutorily permissible distributions by ACE INA’s insurance subsidiaries to ACE INA as well as other group resources. ACE INA received no dividends from its subsidiaries during the six months ended June 30, 2014 and 2013 .

Cash Flows

Our sources of liquidity include cash from operations, routine sales of investments, and financing arrangements. The following is a discussion of our cash flows for the six months ended June 30, 2014 and 2013 .

Operating cash flows were $2.1 billion in the six months ended June 30, 2014 , compared with $1.8 billion in the prior year period, primarily due to $569 million of higher net premiums collected, partially offset by higher losses paid of $267 million.

Cash used for investing was $1.5 billion in the six months ended June 30, 2014 , compared with $2.4 billion in the prior year period. The decrease in cash flows used for investing activities was primarily due to cash paid for acquisitions in the prior year of $977 million compared with $172 million in the current year. Refer to Note 2 to the Consolidated Financial Statements for additional information on our acquisitions.

Cash used for financing was $625 million in the six months ended June 30, 2014 , compared with cash flows from financing of $658 million in the prior year period. Financing cash flows for the six months ended June 30, 2014 included $500 million of repayments of long-term debt, $557 million of share repurchases, and $428 million of dividends paid on Common Shares, partially offset by proceeds from the issuance of long-term debt of $699 million. Cash flows from financing for the six months ended June 30, 2013 included $947 million of proceeds from the issuance of long-term debt, partially offset by $212 million of share repurchases and $169 million of dividends paid on Common Shares. Dividends paid were lower in the prior year due to the accelerated payment of the fourth quarter 2012 dividend in December 2012, which would normally have been paid during the first quarter 2013.

Both internal and external forces influence our financial condition, results of operations, and cash flows. Claim settlements, premium levels, and investment returns may be impacted by changing rates of inflation and other economic conditions. In many cases, significant periods of time, ranging up to several years or more, may lapse between the occurrence of an insured loss, the reporting of the loss to us, and the settlement of the liability for that loss.

In the current low interest rate environment, we use repurchase agreements as a low-cost alternative for short-term funding needs and to address short-term cash timing differences without disrupting our investment portfolio holdings. At June 30, 2014 , there were $1.4 billion in repurchase agreements outstanding.

In May 2014, we issued $700 million of 3.35 percent senior notes due May 2024. The proceeds from the debt issuance are expected to be used to repay at maturity the $700 million of 2.6 percent senior notes due November 2015. In June 2014, ACE INA Holdings Inc.'s $ 500 million of 5.875 percent senior notes matured and were fully paid.

For the period July 1, 2014 through July 29, 2014, we repurchased 1,281,630 Common Shares for a total of $133 million in a series of open market transactions. At July 29, 2014, $1.24 billion in share repurchase authorization remained through December 31, 2014.

We generally maintain the ability to issue certain classes of debt and equity securities via an unlimited Securities and Exchange Commission (SEC) shelf registration which is renewed every three years. This allows us capital market access for refinancing as well as for unforeseen or opportunistic capital needs. Our current shelf registration on file with the SEC expires in December 2014.

We have paid dividends each quarter since we became a public company in 1993. Under Swiss law, dividends must be stated in Swiss francs though dividend payments are made by ACE in U.S. dollars. Refer to Note 8 to the Consolidated Financial Statements for a discussion of our dividend methodology. At our May 2013 annual general meeting, our shareholders approved an annual dividend distribution for the following year by way of a par value reduction equal to $2.04 per share, or CHF 1.92 per share, calculated using the USD/CHF exchange rate as published in the Wall Street Journal on May 10, 2013. The annual dividend approved in May 2013 was paid in four quarterly installments, in accordance with the shareholder resolution.

At the January 10, 2014 Extraordinary General Meeting, our shareholders approved a resolution to increase our quarterly dividend 24 percent from $ 0.51 per share to $0.63 per share for the payment made on January 31, 2014 and April 17, 2014, with the $0.12 per share increase for each installment distributed from capital contribution reserves (and the $ 0.51 per share distributed by way of par value reduction).

At our May 2014 annual general meeting, our shareholders approved an annual dividend distribution for the following year by way of a par value reduction equal to $2.60 per share, or CHF 2.28 per share, calculated using the USD/CHF exchange rate as published in the Wall Street Journal on May 9, 2014, payable in four quarterly installments.

The following table represents dividends paid per Common Share to shareholders of record on each of the following dates:

Shareholders of record as of:	Dividends paid as of:
January 13, 2014	January 31, 2014	$0.63 (CHF 0.55)
March 28, 2014	April 17, 2014	$0.63 (CHF 0.55)
July 23, 2014	August 13, 2014	$0.65 (CHF 0.58)

ITEM 3. Quantitative and Qualitative Disclosures about Market Risk

Refer to Item 7A included in our 2013 Form 10-K.

Reinsurance of GMDB and GLB guarantees

Net income is directly impacted by changes in benefit reserves calculated in connection with reinsurance of variable annuity guarantees, primarily GMDB and GLB. Benefit reserves are calculated in accordance with guidance related to accounting and reporting by insurance enterprises for certain non-traditional long-duration contracts and for separate accounts. Changes in benefit reserves are reflected as policy benefits expense, which is included in life underwriting income. In addition, net income is directly impacted by the change in the fair value of the GLB liability (FVL), which is classified as a derivative for accounting purposes. The FVL established for a GLB reinsurance contract represents the difference between the fair value of the contract and the benefit reserves. Changes in the FVL, net of associated changes in the calculated benefit reserves, are reflected as realized gains or losses.

ACE views its variable annuity reinsurance business as having a similar risk profile to that of catastrophe reinsurance with the probability of long-term economic loss relatively small, at the time of pricing. Adverse changes in market factors and policyholder behavior will have an impact on both life underwriting income and net income. When evaluating these risks, we expect to be compensated for taking both the risk of a cumulative long-term economic net loss, as well as the short-term accounting variations caused by these market movements. Therefore, we evaluate this business in terms of its long-term economic risk and reward.

At June 30, 2014 , management established benefit reserves based on the benefit ratio calculated using assumptions reflecting management’s best estimate of the future performance of the variable annuity line of business. Management exercises judgment in determining the extent to which short-term market movements impact the benefit reserves. The benefit reserves are based on the calculation of a long-term benefit ratio (or loss ratio) for the variable annuity guarantee reinsurance. Despite the long-term nature of the risk, the benefit ratio calculation is impacted by short-term market movements that may be judged by management to be temporary or transient. Management’s best estimate reflected a judgment that the equity markets will exhibit growth somewhat lower than historical average levels. Management regularly examines both quantitative and qualitative analysis and for the quarter ended June 30, 2014 , determined that no change to the benefit ratio was warranted.

The guidance requires us to “regularly evaluate estimates used and adjust the liability balance... if actual experience or other evidence suggests that earlier assumptions should be revised.” ACE evaluates its estimates regularly and management uses judgment to determine the extent to which assumptions underlying the benefit ratio calculation used to establish benefit reserves should be adjusted. The benefit ratio is calculated based on management’s expectation for the short-term and long-term performance of the variable annuity guarantee liability. Management’s quantitative analysis includes a review of the differential between the benefit ratio used at the most recent valuation date and the benefit ratio calculated on subsequent dates.

Benefit reserves and FVL calculations are directly affected by market factors, including equity levels, interest rate levels, credit risk, and implied volatilities, as well as policyholder behaviors, such as annuitization and lapse rates. The tables below assume no changes to the benefit ratio used to establish benefit reserves at June 30, 2014 and show the sensitivity, at June 30, 2014 , of the FVL associated with the variable annuity guarantee reinsurance portfolio. In addition, the tables below present the sensitivity of the fair value of specific derivative instruments held (hedge value) to partially offset the risk in the variable annuity guarantee reinsurance portfolio. The tables below are estimates of the sensitivities to instantaneous changes in economic inputs or actuarial assumptions.

The tables below do not reflect the expected quarterly run rate of net income generated by the variable annuity guarantee reinsurance portfolio if markets remain unchanged during the period. All else equal, if markets remain unchanged during the period, the Gross FVL will increase, resulting in a realized loss. The realized loss occurs primarily because, during the period, we will collect premium while paying little or no claims on our GLB reinsurance (since most policies are not eligible to annuitize until after June 30, 2014 ). This increases the Gross FVL because future premiums are lower by the amount collected in the quarter, and also because future claims are discounted for a shorter period. We refer to this increase in Gross FVL as “timing effect”. The unfavorable impact of timing effect on our Gross FVL in a quarter is not reflected in the sensitivity tables below. For this reason, when using the tables below to estimate the sensitivity of Gross FVL in the third quarter to various changes, it is necessary to assume an additional $5 million to $45 million increase in Gross FVL and realized losses. However, the impact to Net income is substantially mitigated because this realized loss is expected to be exceeded by the positive quarterly run rate of life underwriting income generated by the variable annuity guarantee reinsurance portfolio if markets remain unchanged during

the period. Note that both the timing effect and the quarterly run rate of life underwriting income change over time as the book ages.

The above tables assume equity shocks impact all global equity markets equally and that the interest rate shock is a parallel shift in the U.S. yield curve. Our liabilities are sensitive to global equity markets in the following proportions: 70 percent— 80 percent U.S. equity, 10 percent— 20 percent international equity ex-Japan, 5 percent— 15 percent Japan equity. Our current hedge portfolio is sensitive to global equity markets in the following proportions: 100 percent U.S. equity. We would suggest using the S&P 500 index as a proxy for U.S. equity, the MSCI EAFE index as a proxy for international equity, and the TOPIX as a proxy for Japan equity.

Our liabilities are also sensitive to global interest rates at various points on the yield curve, mainly the U.S. Treasury curve in the following proportions: 0 percent— 10 percent short-term rates (maturing in less than 5 years), 20 percent— 30 percent medium-term rates (maturing between 5 years and 10 years, inclusive), and 65 percent— 75 percent long-term rates (maturing

beyond 10 years). A change in AA-rated credit spreads (AA-rated credit spreads are a proxy for both our own credit spreads and the credit spreads of the ceding insurers) impacts the rate used to discount cash flows in the fair value model. The hedge sensitivity is from June 30, 2014 market levels.

The above sensitivities are not directly additive because changes in one factor will affect the sensitivity to changes in other factors. Also, the sensitivities do not scale linearly and may be proportionally greater for larger movements in the market factors. Sensitivities may also vary due to foreign exchange rate fluctuations. The calculation of the FVL is based on internal models that include assumptions regarding future policyholder behavior, including lapse, annuitization, and asset allocation. These assumptions impact both the absolute level of the FVL as well as the sensitivities to changes in market factors shown above. Additionally, actual sensitivity of our net income may differ from those disclosed in the tables above due to differences between short-term market movements and management judgment regarding the long-term assumptions implicit in our benefit ratios. Furthermore, the sensitivities above could vary by multiples of the sensitivities in the tables above.

Variable Annuity Net Amount at Risk

The tables below present the net amount at risk at June 30, 2014 following an immediate change in equity market levels, assuming all global equity markets are impacted equally. For further information on the net amount at risk, refer to Note 5 to the Consolidated Financial Statements.

a) Reinsurance covering the GMDB risk only

(in millions of U.S. dollars, except percentages)	Equity Shock — +20%	Flat	-20%	-40%	-60%	-80%
GMDB net amount at risk	$ 427	$ 601	$ 1,078	$ 1,656	$ 1,707	$ 1,463
Claims at 100% immediate mortality	823	676	386	291	265	241

The treaty claim limits function as a ceiling on the net amount at risk as equity markets fall. In addition, the claims payable if all of the policyholders were to die immediately declines as equity markets fall due to the specific nature of these claim limits, many of which are annual claim limits calculated as a percentage of the reinsured account value. There is also some impact due to a small portion of the GMDB reinsurance under which claims are positively correlated to equity markets (claims decrease as equity markets fall).

b) Reinsurance covering the GLB risk only

(in millions of U.S. dollars, except percentages)	Equity Shock — +20%	Flat	-20%	-40%	-60%	-80%
GLB net amount at risk	$ 64	$ 173	$ 684	$ 1,633	$ 2,346	$ 2,835

The treaty claim limits cause the net amount at risk to increase at a declining rate as equity markets fall.

c) Reinsurance covering both the GMDB and GLB risks on the same underlying policyholders

(in millions of U.S. dollars, except percentages)	Equity Shock — +20%	Flat	-20%	-40%	-60%	-80%
GMDB net amount at risk	$ 44	$ 69	$ 106	$ 146	$ 180	$ 208
GLB net amount at risk	51	142	478	1,098	1,745	2,273
Claims at 100% immediate mortality	21	64	369	612	821	1,012

The treaty limits control the increase in the GMDB net amount at risk as equity markets fall. The GMDB net amount at risk continues to grow as equity markets fall because most of these reinsurance treaties do not have annual claim limits calculated as a percentage of the underlying account value.

The treaty limits cause the GLB net amount at risk to increase at a declining rate as equity markets fall.
