ACE Limited and Subsidiaries

1 . General

Basis of presentation
ACE Limited is a holding company incorporated in Zurich, Switzerland. ACE Limited, through its various subsidiaries, provides a broad range of insurance and reinsurance products to insureds worldwide. ACE operates through the following business segments: Insurance – North American 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 2012 Form 10-K.

2 . Acquisitions

PT Asuransi Jaya Proteksi
We acquired 80 percent of PT Asuransi Jaya Proteksi (JaPro) on September 18, 2012 and our local partner acquired the remaining 20 percent on January 3, 2013. JaPro is one of Indonesia's leading general insurers. The total purchase price for 100 percent of the company was approximately $ 107 million in cash. JaPro operates in our 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 expands our global franchise in the surety business and enhances our existing commercial lines and personal accident insurance business in Mexico.

The acquisition generated $117 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 preliminary purchase price allocation. The other intangible assets primarily relate to customer lists. 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.

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 $235 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 $142 million based on ACE’s preliminary 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.

As discussed in Note 3 c ), if a credit loss is indicated on an impaired fixed maturity, an OTTI is considered to have occurred and the portion of the impairment not related to credit losses (non-credit OTTI) is recognized in OCI. Included in the “OTTI Recognized in AOCI” columns above are the cumulative amounts of non-credit OTTI recognized in OCI adjusted for subsequent sales, maturities, and redemptions. OTTI recognized in AOCI does not include the impact of subsequent changes in fair value of the related securities. In periods subsequent to a recognition of OTTI in OCI, changes in the fair value of the related fixed maturities are reflected in Unrealized appreciation (depreciation) in the consolidated statement of shareholders’ equity. For the three and six months ended June 30, 2013 , $1 million and $25 million of net unrealized appreciation related to such securities is included in OCI. For the three and six months ended June 30, 2012 , $16 million and $84 million of net unrealized appreciation related to such securities is included in OCI. At June 30, 2013 and December 31, 2012 , AOCI includes net

unrealized depreciation of $2 million and $25 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 85 percent of the total mortgage-backed securities at June 30, 2013 and December 31, 2012 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.

The following table presents fixed maturities by contractual maturity:

c ) Net realized gains (losses)
In accordance with guidance related to the recognition and presentation of OTTI, when an impairment related to a fixed maturity has occurred, OTTI is required to be recorded in Net income if management has the intent to sell the security or it is more likely 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.

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. We develop these estimates using information based on market observable data, issuer-specific information, and credit ratings. ACE developed its default assumption by using 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. We believe that use of a default assumption in excess of the historical mean is reasonable in light of current market conditions.

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 the three and six months ended June 30, 2012 , credit losses recognized in Net income for corporate securities were $1 million and $4 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, 2013 , there were no credit losses recognized in Net income for mortgage-backed securities. For the three and six months ended June 30, 2012 , credit losses recognized in Net income for mortgage-backed securities were nil and $3 million , respectively.

d) Gross unrealized loss
At June 30, 2013 , there were 6,267 fixed maturities out of a total of 23,938 fixed maturities in an unrealized loss position. The largest single unrealized loss in the fixed maturities was $5 million. There were 74 equity securities out of a total of 188 equity securities in an unrealized loss position. The largest single unrealized loss in the equity securities was $40 million. Fixed maturities in an unrealized loss position at June 30, 2013 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. Equity securities in an unrealized loss position at June 30, 2013 included foreign fixed income securities held in a commingled fund structure for which fair value declined primarily due to widening credit spreads since the date of purchase.

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 LOCs and derivative transactions. Included in restricted assets at June 30, 2013 and December 31, 2012 , are fixed maturities and short-term investments totaling $16.0 billion and $16.6 billion, respectively, and cash of $71 million and $139 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 in an orderly transaction between market participants and establishes a three-level valuation hierarchy in which inputs into valuation techniques used to measure fair value are classified. 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 one or more pricing services to obtain fair value measurements for the majority of the investment securities we hold. 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 typically 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, the valuation of fixed maturities 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 the estimated fair value of an investment 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 exchange-traded 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 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. Our position in credit default swaps is typically included within Level 3. Other derivative instruments are recorded in 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. In general, the base lapse function assumes low lapse rates (ranging from about 1 percent to 6 percent per annum) during the surrender charge period of the GMIB contract, followed by a “spike” lapse rate (ranging from about 10 percent to 30 percent per annum) in the year immediately following the surrender charge period, and then reverting to an ultimate lapse rate (generally around 10 percent per annum), typically over a 2 -year period. This base rate is adjusted downward for policies with more valuable guarantees (policies with guaranteed values far in excess of their account values) by multiplying the base lapse rate by a factor ranging from 15 percent to 75 percent . Additional lapses due to partial withdrawals and older policyholders with tax-qualified contracts (due to required minimum distributions) are also included.

The 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. In general ACE assumes that GMIB annuitization rates will be higher for policies with more valuable guarantees (policies with guaranteed values far in excess of their account values). In addition, we also assume that GMIB annuitization rates are higher in the first year immediately following the waiting period (the first year the policies are eligible to annuitize using the GMIB) in comparison to all subsequent years. We do not yet have a robust set of annuitization experience because most of our clients’ policyholders are not yet eligible to annuitize using the GMIB. However, for certain clients representing approximately 37 percent of the total GMIB guaranteed value there are several years of annuitization experience. For these clients the annuitization function reflects the actual experience and has a maximum annuitization rate per annum of 8 percent (a higher maximum applies in the first year a policy is eligible to annuitize using the GMIB—it is over 13 percent ). For most clients, there is not a credible amount of observable relevant behavior data and so we use a weighted-average (with a heavier weighting on the observed experience noted previously) of three different annuitization functions with maximum annuitization rates per annum of 8 percent , 12 percent , and 30 percent , respectively (with significantly higher rates in the first year a policy is eligible to annuitize using the GMIB). The GMIB reinsurance treaties include claim limits to protect ACE in the event that actual annuitization behavior is significantly higher than expected.

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, 2013 , no material changes were made to actuarial or behavioral assumptions.

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 value 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.

The following table presents the significant unobservable inputs used in the Level 3 liability valuations. Excluded from the table below are inputs used to fair value Level 3 assets which are based on single broker quotes or net asset value and contain no quantitative unobservable inputs developed by management.

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.

At June 30, 2013 , reported liabilities for GMDB and GLB reinsurance were $92 million and $880 million, respectively, compared with $90 million and $1.4 billion, respectively, at December 31, 2012 . The reported liability of $880 million for GLB reinsurance at June 30, 2013 and $1.4 billion at December 31, 2012 includes a fair value derivative adjustment of $ 652 million and $1.1 billion, respectively. Included in Net realized gains (losses) in the table above are gains (losses) related to foreign exchange and other fair value derivative adjustments. 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, 2013 and December 31, 2012 , the net amount at risk from reinsurance programs covering the GMDB risk only was $884 million and $1.3 billion, 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, 2013 and December 31, 2012 , 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 1.0 percent and 2.0 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 the GMDB risk only, if all the cedants’ policyholders were to die immediately at June 30, 2013 was approximately $563 million. This takes into account all applicable reinsurance treaty claim limits.

(ii) Reinsurance covering the GLB risk only
At June 30, 2013 and December 31, 2012 , the net amount at risk from reinsurance programs covering the GLB risk only was $302 million and $445 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, 2013 and December 31, 2012 , 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, 2013 and December 31, 2012 , the GMDB net amount at risk from reinsurance programs covering both the GMDB and GLB risks on the same underlying policyholders was $95 million and $116 million, respectively.

At June 30, 2013 and December 31, 2012 , the GLB net amount at risk from reinsurance programs covering both the GMDB and GLB risks on the same underlying policyholders was $341 million and $655 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, 2013 and December 31, 2012 , respectively);	

•	there are no lapses, or withdrawals;	

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

•	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 2.0 percent and 3.0 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, 2013 was approximately $300 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 68 years.

6 . Debt

In March 2013, ACE INA Holdings, Inc. issued $ 475 million of 2.70 percent senior notes due March 2023 and $ 475 million of 4.15 percent senior notes due March 2043.  The 2.70 percent senior notes and 4.15 percent 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 0.10 percent and 0.15 percent , respectively). The notes are also redeemable at par plus accrued and unpaid interest in the event of certain changes in tax law. These notes do not have the benefit of any sinking fund.  These senior unsecured notes are guaranteed on a senior basis by 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 June 2013, we reclassified $500 million of 5.875 percent senior notes, due to mature on June 15, 2014, from Long-term debt to Short-term debt in the consolidated balance sheet.

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. Along with convertible bonds and to be announced mortgage-backed securities (TBA), discussed below, these are the most numerous and frequent derivative transactions.

ACE maintains positions in convertible bond investments that contain embedded derivatives. In addition, ACE, from time to time, purchases TBAs as part of its investing activities. These securities are included within the fixed maturities available for sale (FM AFS) portfolio. At June 30, 2013 , ACE had no positions in TBAs.

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 Accounts payable, accrued expenses, and other liabilities (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, 2013 , ACE had no in-force interest rate swaps.

ACE, from time to time, buys credit default swaps to mitigate global credit risk exposure, primarily related to reinsurance recoverables. At June 30, 2013 , ACE had no in-force credit default 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.

On January 1, 2013, we adopted new guidance that requires disclosure of financial instruments subject to a master netting agreement.  At June 30, 2013 and December 31, 2012, derivative assets of $63 million and $35 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 June 30, 2013 and December 31, 2012, our repurchase obligations of $1,401 million were fully collateralized.  At June 30, 2013 and December 31, 2012, our securities lending payable was $1,665 million and $1,795 million, respectively, and our securities lending collateral was $1,662 million and $1,791 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.

Credit default swaps
A credit default swap is a bilateral contract under which two counterparties agree to isolate and separately trade the credit risk of at least one third-party reference entity. Under a credit default swap agreement, ACE as a protection buyer pays a periodic fee to a protection seller in exchange for a contingent payment by the seller upon a credit event (such as a default or failure to pay) related to the reference entity. When a credit event is triggered, the protection seller pays the protection buyer the difference between the fair value of assets and the principal amount.

(iii) Convertible security investments
A convertible bond is a debt instrument that can be converted into a predetermined amount of the issuer’s equity at certain times prior to the bond’s maturity. The convertible option is an embedded derivative within the fixed maturity host instruments which are classified in the investment portfolio as available for sale. ACE purchases convertible bonds 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, 2013 , included in Other investments in the consolidated balance sheet are investments in limited partnerships and partially-owned investment companies with a carrying value of $1,796 million. In connection with these investments, we have commitments that may require funding of up to $1,144 million over the next several years. 

c) Taxation
In April 2012, ACE reached final settlement with the Internal Revenue Service (IRS) Appeals Division regarding several issues raised by the IRS Examination Division in its federal tax returns for 2005, 2006 and 2007. The settlement of these issues had no net impact on our results of operations. In addition, the IRS completed its field examination of ACE’s federal tax returns for 2008 and 2009 during June 2012. No material adjustments resulted from this examination. During the three and six months ended June 30, 2013, ACE reduced the amount of unrecognized tax benefits by $5 million resulting from the closing of applicable statutes of limitations. As of June 30, 2013, $22 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) Legal proceedings
Claims and other litigation
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 the 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 2011 annual general meeting, our shareholders approved a dividend for the following year, payable in four quarterly installments after the May 2011 annual general meeting from our capital contribution reserves (Additional paid-in capital), a subaccount of legal reserves. At our May 2012 and May 2013 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. We have determined this procedure is more appropriate for us at this time due to current Swiss law. 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 ). 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 27.95 at June 30, 2013 .

For the three and six months ended June 30, 2012 , dividends per Common Share amounted to CHF 0.48 ($ 0.49 ) and CHF 1.01 ($ 1.08 ), which included a $0.12 per Common Share increase (approved by our shareholders at the January 9, 2012 extraordinary general meeting) to the third and fourth installments of the dividend approved at the May 2011 annual general meeting. For the six months ended June 30, 2012 , dividends per Common Share included a par value reduction of CHF 0.48 per Common Share.

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, 2013 , 2,746,143 Common Shares remain in treasury after net shares redeemed under employee share-based compensation plans.

ACE Limited securities repurchase authorization
In August 2011, the Board of Directors (Board) authorized the repurchase of up to $ 303 million of ACE’s Common Shares through December 31, 2012. The amount authorized in August 2011 was in addition to the $ 197 million balance remaining under a $ 600 million share repurchase program approved in November 2010. In November 2012, the Board authorized an extension of our then-remaining repurchase capacity through December 31, 2013. These authorizations were granted to allow ACE to repurchase Common Shares to partially offset potential dilution from the exercise of stock options and the granting of restricted stock under share-based compensation plans. Such repurchases may be made in the open market, in privately negotiated transactions, block trades, accelerated repurchases and/or through option or other forward transactions. For the three and six months ended June 30, 2013 , ACE repurchased 654,776 Common Shares for a cost of $ 58 million and 2,463,076 Common Shares for a cost of $212 million , respectively, in a series of open market transactions. At June 30, 2013 , $249 million in share repurchase authorization remained through December 31, 2013 pursuant to the November 2010, August 2011, and November 2012 Board authorizations.

9 . Share-based compensation

The ACE Limited 2004 Long-Term Incentive Plan (the 2004 LTIP) provides for grants of both incentive and non-qualified stock options principally at an option price per share equal to the fair value of ACE’s Common Shares on the date of grant. Stock options are generally granted with a 3-year vesting period and a 10-year term. The stock options vest in equal annual installments over the respective vesting period, which is also the requisite service period. On February 28, 2013 , ACE granted 1,815,896 stock options with a weighted-average grant date fair value of $17.29 each. The fair value of the options issued is estimated on the date of grant using the Black-Scholes option pricing model.

The 2004 LTIP also provides for 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 day of grant. On February 28, 2013 , ACE granted 1,345,850 restricted stock awards and 266,065 restricted stock units to employees and officers of ACE and its subsidiaries with a grant date fair value of $85.39 each. Each restricted stock unit represents our obligation to deliver to the holder one Common Share upon vesting.

In May 2013, our shareholders approved an increase of 8 million shares authorized to be issued under the 2004 LTIP, bringing the total shares authorized to 38,600,000 common shares. At June 30, 2013, a total of 11,120,629 shares remain available for future issuance under the 2004 LTIP.

10 . Segment information

ACE operates through the following 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.

Effective first quarter 2013, the Insurance – North American segment is presented in two distinct reportable segments: Insurance – North American P&C and Insurance – North American Agriculture. Prior year amounts contained in this report have been adjusted to conform to the new segment presentation.

For segment reporting purposes, certain items have been presented in a different manner 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 Life business, management also 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 underwriting income. For example, for the three months ended June 30, 2013 , Life underwriting income of $ 96 million includes Net investment income of $ 63 million and losses from fair value changes in separate account assets of $ 11 million.

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:
		
•	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;

•	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; 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;	
		
•	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;

•	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, and 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;	
		
•	judicial decisions and rulings, new theories of liability, legal tactics, and settlement terms;	
		
•	the effects of public company bankruptcies and/or accounting restatements, as well as disclosures by and investigations of public companies relating to possible accounting irregularities, and other corporate governance issues, including the effects of such events on:	
		
•	the capital markets;	
		
•	the markets for directors and officers (D&O) and errors and omissions (E&O) insurance; and	
		
•	claims and litigation arising out of such disclosures or practices by other companies;

•	uncertainties relating to governmental, legislative and regulatory policies, developments, actions, investigations and treaties, which, among other things, could subject us to insurance regulation or taxation in additional jurisdictions or affect our current operations;	
		
•	the actual amount of new and renewal business, market acceptance of our products, and risks associated with the introduction of new products and services and entering new markets, including regulatory constraints on exit strategies;	
		
•	the competitive environment in which we operate, including trends in pricing or in policy terms and conditions, which may differ from our projections and changes in market conditions that could render our business strategies ineffective or obsolete;	
		
•	acquisitions made by us performing differently than expected, our failure to realize anticipated expense-related efficiencies or growth from acquisitions, the impact of acquisitions on our pre-existing organization or announced acquisitions not closing;	
		
•	risks associated with being a Swiss corporation, including reduced flexibility with respect to certain aspects of capital management and the potential for additional regulatory burdens;	
		
•	the potential impact from government-mandated insurance coverage for acts of terrorism;

•	material differences between actual and expected assessments for guaranty funds and mandatory pooling arrangements;	
		
•	the effects of investigations into market practices in the property and casualty (P&C) industry;	
		
•	changing rates of inflation and other economic conditions, for example, recession;	
		
•	the amount of dividends received from subsidiaries;	
		
•	loss of the services of any of our executive officers without suitable replacements being recruited in a reasonable time frame;

Overview
ACE Limited is the Swiss-incorporated holding company of the ACE Group of Companies. ACE opened its business office in Bermuda in 1985 and continues to maintain operations in Bermuda. ACE, which is headquartered in Zurich, Switzerland, and its direct and indirect subsidiaries, are a global insurance and reinsurance organization, serving the needs of a diverse group of clients around the world. We are predominantly a global P&C insurance company with both a commercial and specialty product orientation. We offer commercial insurance, specialty products and accident and health (A&H) solutions and are expanding our personal lines and international life insurance businesses. As we have grown, we have developed products and diversified our offerings to meet the needs of our customers. At June 30, 2013 , we had total assets of $94 billion and shareholders’ equity of $27 billion.

We operate through the following business segments: Insurance – North American P&C, Insurance – North American Agriculture, Insurance – Overseas General, Global Reinsurance, and Life.

The Insurance – North American P&C segment includes retail divisions ACE USA (including ACE Canada), ACE Commercial Risk Services and ACE Private Risk Services; our wholesale and specialty divisions ACE Westchester, and ACE Bermuda; and various run-off operations, including Brandywine Holdings Corporation (Brandywine). Our retail products range from commercial lines with service offerings such as risk management, loss control and engineering programs, specialty commercial P&C, and A&H coverages to personal lines homeowners, automobile, liability, valuables, and marine coverages. Our wholesale and specialty products include excess and surplus property, D&O, professional liability, inland marine, specialty casualty, environmental, and political risk.

The Insurance – North American Agriculture segment provides coverage for agriculture business, writing a variety of commercial coverages including comprehensive Multiple Peril Crop Insurance (MPCI), crop-hail and farm P&C insurance protection to customers in the U.S. and Canada through Rain and Hail Insurance Service, Inc. (Rain and Hail) as well as specialty P&C insurance coverages offered by ACE Agribusiness to companies that manufacture, process and distribute agriculture products. The MPCI program is offered in conjunction with the U.S. Department of Agriculture (USDA). 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 allow 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.

The Insurance – Overseas General segment comprises ACE International, our retail business serving territories outside the U.S., Bermuda, and Canada; the international A&H business of Combined Insurance (Combined); and the wholesale insurance business of ACE Global Markets (AGM). ACE International has a presence in major developed markets and growing economies serving multinational clients and local customers. A significant amount of our global business is with local companies, offering traditional and specialty P&C products including D&O and professional liability, specialty personal lines, and energy products. ACE International expanded its global business through the acquisitions of ABA Seguros on May 2, 2013 and Fianzas Monterrey on April 1, 2013. Refer to Note 2 to the Consolidated Financial Statements for additional information on these acquisitions. The consolidated financial statements include the results of the acquired businesses from the acquisition dates. Our international A&H business primarily focuses on personal accident and supplemental medical. AGM offers specialty products including aviation, marine, financial lines, energy, and political risk.

The Global Reinsurance segment represents our reinsurance operations comprising ACE Tempest Re Bermuda, ACE Tempest Re USA, ACE Tempest Re International, ACE Tempest Re Canada, and the reinsurance operations of AGM. Global Reinsurance provides solutions for customers ranging from small commercial insureds to multinational ceding companies.

Net premiums written reflect the premiums we retain after purchasing reinsurance protection. Net premiums written increased for the three and six months ended June 30, 2013 primarily in our Insurance – North American P&C segment retail division reflecting growth across a broad range of our product portfolio including our risk management and personal lines businesses, and specialty casualty, property and professional lines reflecting rate increases, exposure changes, strong renewal retention, and new business. Our wholesale and specialty division contributed to the increase in net premiums written from higher production. Net premiums written increased in our Insurance – Overseas General segment for the three and six months ended June 30, 2013 . The growth was driven by the acquisitions of ABA Seguros in May 2013, Fianzas Monterrey in April 2013, and Jaya Proteksi in September 2012. In addition, growth was reported in our retail operations in all of our product lines – P&C, A&H, and personal lines. To a lesser extent, our Life segment added to growth in net premiums written for the three and six months ended June 30, 2013 primarily due to growth in certain A&H program business, which offset the decrease in our Life reinsurance business as no new Life reinsurance business is currently being written. Additionally, life deposits collected for the three and six months ended June 30, 2013 increased over 60 percent primarily due to growth in our Asian markets. However, our Insurance – North American Agriculture segment reported decreases in net premiums written for the three and six months ended June 30, 2013 primarily due to the purchase of proportional reinsurance on the MPCI business for the 2013 crop year, which is in addition to the excess of loss reinsurance coverage historically purchased. The reinsurance related decrease was partially offset by increased production in the MPCI business and in our agriculture's unit property and casualty business. Our Global Reinsurance segment also reported a decrease in net premiums written for the three months ended June 30, 2013 due primarily to increased property catastrophe cessions to a newly formed reinsurance sidecar, Altair Re, that more than offset strong renewal retention and new business written. For the six months ended June 30, 2013, Global Reinsurance net premiums written were relatively flat as the increased cessions were substantially offset by higher premiums written, primarily in our U.S. property and U.S. automobile lines of business.

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, 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, 2013 in the Insurance – North American P&C segment primarily due to the increase in net premiums written as described above. Growth in our retail division was partially offset by lower earned premiums from our program business. Net premiums earned increased for the three and six months ended June 30, 2013 in our Insurance – Overseas General segment driven by strong performances in all product lines and the acquisitions described above. Net premiums earned increased for the three and six months ended June 30, 2013 in our Global Reinsurance segment primarily in our U.S. property line of business from higher premiums written in the current and prior years. Net premiums earned increased for the three and six months ended June 30, 2013 in our Life segment primarily due to growth in our Asian markets. However, net premiums earned decreased for the three and six months ended June 30, 2013 in our Insurance – North American Agriculture segment primarily due to higher reinsurance costs for the MPCI business.

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.

Loss and loss expense ratio, adjusted	60.0	 %	 	61.2	 %	 	59.3	 %	 	60.4	 %	
Total net pre-tax catastrophe losses, excluding related reinstatement premiums, were $ 81 million and $ 113 million for the three and six months ended June 30, 2013 , compared with $55 million and $74 million in the prior year periods, respectively. Catastrophe losses through June 30, 2013 were primarily related to flooding in Canada and Australia and severe weather-related events in the U.S. Catastrophe losses in the prior year periods were primarily related to severe weather-related events in the U.S. The adjusted loss and loss expense ratio decreased for the three and six months ended June 30, 2013 primarily due to an improved current accident year loss ratio in several lines of business in several regions.

Prior period development arises from changes to loss estimates recognized in the current year that relate to loss reserves first reported in previous calendar years and excludes the effect of losses from the development of earned premium from previous accident years. We experienced net favorable prior period development of $ 128 million and $ 198 million for the three and six months ended June 30, 2013 , respectively. This compares with net favorable prior period development of $113 million and $206 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, 2013 was $534 million and $1.1 billion compared with $537 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 decreased for the three and six months ended June 30, 2013 primarily due to the acquisitions described above, which carry a lower acquisition rate than our other businesses.

Our administrative expense ratio increased slightly for the three months ended June 30, 2013 due primarily to an expense adjustment in the current period. The administrative expense ratio improved slightly for the six months ended June 30, 2013 primarily due to the favorable impact of a legal settlement, offset by expense adjustments in the current year period.

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 11.5 percent and 11.4 percent for the three and six months ended June 30, 2013 , respectively. Our effective income tax rate was 31.0 percent and 16.6 percent for the three and six months ended June 30, 2012, respectively. The decrease in effective tax rate was primarily due to net realized losses on derivatives generated in lower tax paying jurisdictions in the prior year. In addition, the effective tax rate was lower due to net

realized gains on derivatives as well as a higher percentage of earnings being generated in lower tax paying jurisdictions during the current year.

Prior Period Development
The favorable prior period development (PPD) of $128 million and $198 million during the three and six months ended June 30, 2013 , respectively, was the net result of several underlying favorable and adverse movements. For the three and six months ended June 30, 2012 , we experienced favorable PPD of $113 million and $206 million, respectively. In the sections following the tables below, significant prior period movements within each reporting segment are discussed in more detail. 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.

Insurance – North American P&C
Insurance – North American P&C experienced net favorable PPD of $47 million in the three months ended June 30, 2013 , which was the net result of several underlying favorable and adverse movements, driven by the following principal changes:

•	Net favorable development of $19 million on long-tail business, including:	

•	Net favorable development of $28 million on 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 impacting the 2012 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;	

•	Favorable development of $14 million impacting the 2009 accident year primarily related to lower than expected case incurred loss activity in first dollar product lines within our national accounts portfolio;	

•	Net favorable development of $14 million impacting the 2008 accident year which consisted of $14 million adverse development in excess automobile and general liability and $28 million favorable development on excess and high deductible workers' compensation lines. The adverse activity in automobile and general liability was a function of higher than expected incurred activity on a small number of large losses. The favorable activity in workers' compensation was due to lower levels of reported losses than anticipated in our prior review and original pricing assumptions; and	

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

•	Net favorable development of $11 million in our wholesale D&O product line affecting accident years 2004 through 2008. The favorable development was largely due to reductions in estimates of ultimate exposure on a few large claims;	

•	Net adverse development of $24 million on our Brandywine run-off portfolios of general liability and workers' compensation product lines impacting the 1995 and prior accident years. Loss activity was higher than expected in these portfolios; and	

•	Net favorable development of $4 million across a number of lines and accident years, none of which was significant individually or in the aggregate.	

•	Net favorable development of $28 million on short-tail business, including:	

•	Net favorable development of $15 million on wholesale property, primarily impacting the 2011 and 2012 accident years. Paid and reported loss activity was lower than expected since our prior review for these accident years; and	

•	Net favorable development of $13 million across a number of lines and accident years, none of which was significant individually or in the aggregate.	

Insurance – North American P&C experienced net favorable PPD of $57 million in the three months ended June 30, 2012 , which was the net result of several underlying favorable and adverse movements, driven by the following principal changes:

•	Net favorable development of $24 million on long-tail business, including:	

•	Net favorable development of $38 million on our national accounts portfolios which consist of commercial automobile liability, general liability, and workers' compensation lines of business. This favorable development was the net impact of favorable and adverse movements, including:	

49 

Table of Contents

		
•	Favorable development of $41 million on the 2011 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;	

•	Favorable development of $34 million in the 2007 accident year, primarily in workers' compensation. Loss activity through March 31, 2012 was lower than expected and was included in the review completed during the three months ended June 30, 2012, in which we have increased the weighting on experience-based methods. The favorable development was the combined effect of this lower than expected incurred loss activity and our change in method weights; and	

•	Adverse development of $37 million affecting the 2006 and prior accident years largely in workers' compensation. The causes for this adverse movement were numerous and included large increases in a small number of claims, higher than expected loss activity in a few accident years, changes in our weighting of experience-based methods, and a refinement of our treatment of ceded reinsurance recoveries on a few select treaties due to information which became known since our prior review.	

•	Adverse development of $14 million in other long-tail business across a number of lines and accident years, none of which was significant individually or in the aggregate.	

•	Favorable development of $33 million on short-tail business, including:	

•	Favorable development of $23 million in our general aviation product lines (both hull and liability) affecting the 2009 and prior accident years. Actual paid and incurred loss activity continued to be lower than expected based on long term historical averages leading to a reduction in our estimate of ultimate losses; and	

•	Favorable development of $10 million in other short-tail business across a number of lines and accident years, none of which was significant individually or in the aggregate.	

Insurance – North American Agriculture
Insurance – North American Agriculture experienced favorable PPD of nil and $2 million in the three months ended June 30, 2013 and 2012 , respectively, on short-tail business across a number of accident years, none of which was significant individually or in the aggregate.

Insurance – Overseas General
Insurance – Overseas General experienced net favorable PPD of $52 million in the three months ended June 30, 2013 , which was the net result of several underlying favorable and adverse movements, driven by the following principal changes:

•	Net adverse development of $1 million on long-tail business across a number of accident years, none of which was significant individually or in the aggregate.	

•	Favorable development of $53 million on short-tail business, including:	

•	Favorable development of $38 million across short-tail business in accident years 2009 through 2012. Favorable emergence on large losses across the wholesale energy book in accident years 2011 and 2012 and favorable general emergence across the remainder of the short-tail lines was reflected in the quarter; and	

•	Favorable development of $15 million on accident years 2007 and prior for property claims and marine liability. Loss development from these more mature years is mainly the result of favorable developments on specific litigated claims.

Table of Contents

Insurance – Overseas General experienced net favorable PPD of $39 million in the three months ended June 30, 2012 , which was the net result of several underlying favorable and adverse movements, driven by the following principal changes:

•	There was no overall adverse or favorable development on long-tail business in the three months ended June 30, 2012 .	

•	Net favorable development of $39 million on short-tail business, including:	

•	Favorable development of $20 million on wholesale marine business. Favorable loss emergence across much of the short-tail first party marine business in accident years 2010 and 2011 led to lower experience-based indications. In addition, case reductions on specific claims in older accident years drove reserve releases;	

•	Net favorable development of $15 million on short-tail property and technical lines in Continental Europe, excluding catastrophes. Favorable loss emergence in the boiler and machinery (B&M) business, driven by better than expected loss activity on large accounts, primarily in accident years 2010 and 2011 drove most of the reserve release. Adverse movement in fire business in accident year 2011 driven by unfavorable loss emergence across the region mitigated the impact of the favorable B&M reserve release; and	

•	Favorable development of $4 million in other short-tail business across a number of lines and accident years, none of which was significant individually or in the aggregate.	

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

•	Net favorable development of $27 million on long-tail business, including:	

•	Favorable development of $18 million in the casualty line of business principally in treaty years 2007 and prior. Following the reserve studies completed in the three months ended June 30, 2013, we reflected a greater weighting towards experience-based methods. Since experience has tended to be generally favorable compared with assumptions, the changes resulted in the favorable development referenced above;	

•	Favorable development of $18 million in the professional liability/D&O line of business principally in treaty years 2008 and prior. Following the reserve studies completed in the three months ended June 30, 2013, we reflected a greater weighting towards experience-based methods. Since experience has tended to be generally favorable compared with assumptions, the changes resulted in the favorable development referenced above; and	

•	Net adverse development of $9 million in the automobile line of business.  There was $16 million of adverse development related to treaty years 2008 through 2011 where the loss experience was unfavorable due to higher than expected reported claims and greater reliance on experience-based methods. There was also favorable development of $7 million in treaty years 2007 and prior, where experience was generally more favorable.	

•	Net favorable development of $2 million on short-tail business across a number of treaty years, none of which was significant individually or in the aggregate.	

Global Reinsurance experienced net favorable PPD of $15 million in the three months ended June 30, 2012 , which was the net result of several underlying favorable and adverse movements, driven by the following principal changes:

•	Net favorable development of $15 million on long-tail business, including:	

•	Favorable development of $36 million in the casualty line of business principally in treaty years 2007 and prior. Following the reserve studies completed in the three months ended June 30, 2012, we reflected a greater weighting towards experience-based methods. Since experience has tended to be generally favorable compared with assumptions, the changes resulted in the favorable development referenced above;	

•	Net adverse development of $18 million in the professional liability/D&O line of business.  There was $26 million of adverse development related to treaty years 2006 through 2010 where the loss experience was unfavorable due to

higher than expected reported claims and greater reliance on experience-based methods. There was also favorable development of $8 million in treaty years 2004 and prior, where experience was generally more favorable; and

•	Adverse development of $3 million in other long-tail business across a number of treaty years, none of which was significant individually or in the aggregate.	

•	There was no prior period development on short-tail business in the three months ended June 30, 2012.

Net premiums written increased for the three and six months ended June 30, 2013 in our retail division reflecting growth across a broad range of our product portfolio including our risk management business, and specialty casualty, property and professional lines of business reflecting rate increases, exposure changes, strong renewal retention, and new business. In addition, we continued to generate higher personal lines production including growth in the homeowners, automobile, and umbrella business offered through ACE Private Risk Services. Our wholesale and specialty division contributed to the increase in net premiums written for the three and six months ended June 30, 2013 due to higher production from our property and

professional lines of business. For the six months ended June 30, 2013, we also produced higher wholesale casualty written premiums.
Net premiums earned increased for the three and six months ended June 30, 2013 primarily due to the increase in net premiums written as described above. Growth in net premiums earned for the retail division was partially offset by lower earned premiums from our program business.

Net pre-tax catastrophe losses, excluding reinstatement premiums, were $50 million and $61 million for the three and six months ended June 30, 2013 , compared with $45 million and $59 million for the prior year periods, respectively. Catastrophe losses through June 30, 2013 and 2012 were primarily from flooding in Canada and severe weather-related events in the U.S. Net favorable prior period development was $47 million and $ 87 million for the three and six months ended June 30, 2013 , compared with $ 57 million and $108 million in the prior year periods, respectively. Refer to the “Prior Period Development” section for additional information. For the three and six months ended June 30, 2013, the adjusted loss and loss expense ratio decreased as a result of a decrease in the loss and loss expense ratio in several of our professional, personal, and property lines where execution of detailed portfolio management plans has resulted in improved current accident year loss ratio performance, and to a lesser extent due to lower large losses.

The policy acquisition cost ratio decreased for the three and six months ended June 30, 2013 due to growth in certain businesses, primarily risk management, which incur lower acquisition expenses.

The administrative expense ratio decreased for the three and six months ended June 30, 2013 primarily due to growth in certain businesses which incur lower administrative expenses, and for the six months, from the favorable impact of a $29 million legal settlement in the current year.

Net premiums written decreased for the three and six months ended June 30, 2013 primarily due to the purchase of proportional reinsurance on the MPCI business for the 2013 crop year, which is in addition to the excess of loss reinsurance coverage historically purchased.  The reinsurance related decrease in net premiums written was partially offset by increased production in the MPCI business and in our agriculture unit's property and casualty business.   
Net premiums earned decreased for the three and six months ended June 30, 2013 primarily due to higher reinsurance costs for the MPCI business.

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 for the periods indicated:

Net pre-tax catastrophe losses, excluding reinstatement premiums, were $ 3 million for both the three and six months ended June 30, 2013 , compared with $ 4 million and $6 million for the prior year periods, respectively. Net favorable prior period development was nil and $3 million for the three and six months ended June 30, 2013 , compared with $ 2 million and $11 million in the prior year periods, respectively. The adjusted loss and loss expense ratio was relatively flat for the three months ended June 30, 2013. For the six months ended June 30, 2013, the adjusted loss and loss expense ratio decreased due to a decrease in current accident year loss adjustment expenses reflecting a revision in estimated claim handling costs.

Table of Contents

The policy acquisition cost ratio decreased slightly for the three months ended June 30, 2013 . The policy acquisition cost ratio increased for the six months ended June 30, 2013 primarily due to a $14 million benefit in the prior year period related to a revision in estimated agent profit share commissions for the MPCI business. A similar benefit did not occur in the current year.

The administrative expense ratio increased for the three and six months ended June 30, 2013 primarily reflecting higher Administrative and Operating expense (A&O) reimbursements on the MPCI business in the prior year period mainly due to additional reimbursements earned for high loss ratio states and underserved states.

Net premiums written increased for the three and six months ended June 30, 2013 . The growth was driven by the acquisitions of ABA Seguros in May 2013, Fianzas Monterrey in April 2013, and Jaya Proteksi in September 2012. In addition, growth was reported in our retail operations in all of our product lines – P&C, A&H, and personal lines. P&C growth was reported across all regions of our retail operations, led by the U.K. which was driven by moderate price increases, strong renewal retention, and improved new business writings. A&H growth was primarily driven by strong results in Latin America, Asia, and Europe. Personal lines growth reflected new business opportunities in Europe and Asia. A slight decline in wholesale operations, as well as the unfavorable impact of foreign exchange, partially offset this growth.
Net premiums earned increased for the three and six months ended June 30, 2013 driven by strong performance in all product lines and from the acquisitions described above. Regionally, the increase was in our European, Latin American, and Asian operations.

Net pre-tax catastrophe losses, excluding reinstatement premiums, were $17 million and $38 million for the three and six months ended June 30, 2013 , compared with $5 million and $7 million in the prior year periods, respectively. Catastrophe losses through June 30, 2013 were primarily related to flooding in Australia and Canada. Catastrophe losses through June 30, 2012 were primarily a result of flooding in the U.K. Net favorable prior period development was $52 million and $74 million for the three and six months ended June 30, 2013 , compared with $39 million and $61 million in the prior year periods, respectively. Refer to the “Prior Period Development” section for additional information. The adjusted loss and loss expense ratio decreased for the three and six months ended June 30, 2013 due primarily to the reduction in the current accident year loss ratio across several lines of business in several regions and a favorable change in the mix of business. In addition, the decrease for the six months reflects large property losses in the prior year period that did not occur in the current year.

The policy acquisition cost ratio decreased for the three and six months ended June 30, 2013 primarily due to the acquisitions described above, which carry a lower acquisition rate than our other businesses.
The administrative expense ratio decreased for the three and six months ended June 30, 2013 due to the acquisitions described above, which generate lower expenses than our other businesses, and A&H regulatory fees paid in Europe in the prior year period.

Net premiums written decreased for the three months ended June 30, 2013 due to increased property catastrophe cessions to a newly formed reinsurance sidecar, Altair Re, that more than offset strong renewal retention and new business written, primarily in our U.S. property and U.S. automobile lines of business. For the six months ended June 30, 2013, net premiums written were relatively flat as the increased cessions substantially offset the higher premiums written, primarily in our U.S. property and U.S. automobile lines of business.

Net premiums earned increased for the three and six months ended June 30, 2013 primarily in our U.S. property line of business from higher premiums written in the current and prior years.

Net pre-tax catastrophe losses were $11 million for both the three and six months ended June 30, 2013 , compared with $1 million and $2 million in the prior year periods, respectively. Catastrophe losses through June 30, 2013 were primarily related to flooding in Canada and Europe. Net favorable prior period development was $29 million and $34 million for the three and six months ended June 30, 2013 , compared with $15 million and $26 million in the prior year periods, respectively. Refer to the “Prior Period Development” section for additional information. The adjusted loss and loss expense ratio decreased for the three and six months ended June 30, 2013 primarily due to a change in the mix of business towards lower loss ratio products.

The policy acquisition cost ratio increased for the three and six months ended June 30, 2013 primarily due to a change in the mix of business towards products that have a higher acquisition cost ratio.

The administrative expense ratio decreased for the three and six months ended June 30, 2013 as a result of the increase in net premiums earned.

A&H net premiums written increased for the three and six months ended June 30, 2013 due to growth in certain program business and higher production. Life insurance net premiums written were relatively flat for the three and six months ended June 30, 2013 . Life reinsurance net premiums written decreased for the three and six months ended June 30, 2013 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 important indicator of future profitability. The increase in life deposits collected for the three and six months ended June 30, 2013  is primarily 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 three and six months ended June 30, 2013 , realized gains of $101 million and $470 million, respectively, were associated with net decreases in the value of GLB liabilities; these decreases were primarily due to rising equity levels, higher interest rates, and a weakening yen, partially offset by an increased value of GLB liabilities due to the unfavorable impact of discounting future claims for one and two fewer quarters, respectively. In addition, we experienced realized losses of $68 million and $318 million for the three and six months ended June 30, 2013, respectively, 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 2013 due primarily to the acquisitions of Fianzas Monterrey (completed April 1, 2013) and ABA Seguros (completed May 2, 2013). 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, 2013 , the estimated amortization expense related to intangible assets for the third and fourth quarters of 2013 and the next five years:

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 decreased one percent and two percent for the three and six months ended June 30, 2013 , respectively, compared with the prior year periods. The decline in net investment income was primarily due to lower reinvestment rates offset by a higher overall average invested asset base and higher private equity and other distributions.

The investment portfolio’s average market yield on fixed maturities was 2.9 percent and 2.8 percent at June 30, 2013 and 2012 , 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 1.2 percent and 1.1 percent yields on short-term investments for the three and six months ended June 30, 2013 , respectively, reflect the global nature of our insurance operations. For example, yields on short-term investments in Malaysia, Mexico and Indonesia range from 3.0 percent to 6.5 percent .

The 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 represent approximately 58 percent of our equity securities portfolio.

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.

Our Net realized gains (losses) for the three and six months ended June 30, 2013 , included write-downs of $ 7 million and $10 million, respectively, as a result of an other-than-temporary decline in fair value of certain securities. This compares with write-downs of $ 10 million and $20 million for the three and six months ended June 30, 2012 , respectively.

At June 30, 2013, our investment portfolios held by U.S. legal entities included approximately $213 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 $75 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.

We engage in a securities lending program which involves lending investments to other institutions for short periods of time. ACE invests the collateral received in securities of high credit quality and liquidity, with the objective of maintaining a stable principal balance. Certain investments purchased with the securities lending collateral declined in value resulting in an unrealized loss of $3 million at June 30, 2013 . The unrealized loss is attributable to fluctuations in market values of the underlying performing debt instruments held by the respective mutual funds, rather than default of a debt issuer. It is our view that the decline in value is temporary.

______________________________________________________________________________________________________________________
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 4.1 years and 3.9 years at June 30, 2013 and December 31, 2012 , respectively. We estimate that a 100 basis point (bps) increase in interest rates would reduce the valuation of our fixed income portfolio by approximately $2.3 billion at June 30, 2013 .

The fair value of our total investments decreased $751 million during the six months ended June 30, 2013 , primarily due to the negative impact of rising interest rates on the valuation of our portfolio and unfavorable foreign exchange, partially offset by the investing of operating cash flows.
The following tables show the market value of our fixed maturities and short-term investments at June 30, 2013 and December 31, 2012 . The first table lists investments according to type and the second according to S&P credit rating:

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). As of June 30, 2013 , the state of California, including political subdivisions and other municipal issuers within the state, represented approximately 14 percent of our Municipal investments. A majority of the state of California exposure represents special revenue bonds. Over 77 percent of our Municipal investments carry an S&P rating of AA- or better and none carry fair values that reflect a significantly different risk compared to those ratings. These Municipal investments are split 46 percent and 54 percent between general obligation and special revenue bonds, respectively.

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. We have 73 percent of our non-U.S. fixed income portfolio denominated in G7 currencies. The average credit quality of our non-U.S. fixed income securities is A and 54 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.

Our mortgage-backed securities are rated predominantly AA and comprise 20 percent of our fixed income portfolio. This compares with a 31 percent mortgage-backed weighting in representative indices of the U.S. fixed income market at June 30, 2013 . The minimum rating for our initial purchases of mortgage-backed securities is AA for agency mortgages and AAA for non-agency mortgages.

Agency RMBS represent securities which have been issued by Federal agencies (Government National Mortgage Association, Federal National Mortgage Association, and Federal Home Loan Mortgage Corporation) with implied or explicit government guarantees. These represent 97 percent of our total RMBS portfolio.

Our commercial mortgage-backed securities (CMBS) are rated predominantly AAA and broadly diversified with over 13,000 loans with 29 percent of the portfolio issued before 2006 and 52 percent issued after 2009. The average loan-to-value ratio is approximately 64 percent with a debt service coverage ratio in excess of 1.9 and weighted-average subordinated collateral of 31 percent . The cumulative foreclosure rate would have to rise to 44 percent before principal is impaired. The foreclosure rate of our CMBS portfolio at June 30, 2013 was 1.9 percent .

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, 2013 , 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 approximately 1,075 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, 2013 , there were no material changes to our critical accounting estimates. For full discussion of our critical accounting estimates, refer to Item 7 in our 2012 Form 10-K.

Reinsurance recoverable on ceded reinsurance
The following table presents a composition of our reinsurance recoverable for the periods indicated: 

								
 	June 30		 	December 31		
(in millions of U.S. dollars)	2013		 	2012		
Reinsurance recoverable on unpaid losses and loss expenses (1)	$	10,738		 	$	11,399		
Reinsurance recoverable on paid losses and loss expenses  (1)	704		 	679		
Net reinsurance recoverable on losses and loss expenses	$	11,442		 	$	12,078		
Reinsurance recoverable on policy benefits	$	240		 	$	241		
		
(1)  	Net of provision for uncollectible reinsurance	

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 $2.5 billion of collateral at June 30, 2013 and December 31, 2012, respectively. The decrease in net reinsurance recoverable on losses and loss expenses was primarily due to crop activity, the impact of foreign exchange, and favorable PPD.

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. 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 reserves. Loss reserves also include an estimate of expenses associated with processing and settling unpaid claims (loss expenses). At June 30, 2013 , our gross unpaid loss and loss expense reserves were $37.3 billion and our net unpaid loss and loss expense reserves were $26.6 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)	Gross
Losses		 	Reinsurance
Recoverable (1)		 	Net
Losses		
Balance at December 31, 2012	$	37,946		 	$	11,399		 	$	26,547		
Losses and loss expenses incurred	5,490		 	1,314		 	4,176		
Losses and loss expenses paid	(5,784	)	 	(1,873	)	 	(3,911	)

The process of establishing loss reserves for property and casualty claims can be complex and is subject to considerable uncertainty as it requires the use of informed estimates and judgments based on circumstances known at the date of accrual.

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

Asbestos and Environmental (A&E) and Other Run-off Liabilities
There was no unexpected A&E reserve activity during the six months ended June 30, 2013 . Refer to our 2012 Form 10-K for additional information.

Fair value measurements
The accounting guidance on fair value measurements defines fair value as the price to sell an asset or transfer a liability in an orderly transaction between market participants and establishes a three-level valuation hierarchy in which inputs into valuation techniques used to measure fair value are classified.

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). Inputs in Level 1 are unadjusted quoted prices for identical assets or liabilities in active markets. 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

70

Table of Contents

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.

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.

While we obtain values for the majority of the investment securities we hold from one or more pricing services, it is ultimately management’s responsibility to determine whether the values obtained and recorded 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 typically adjust prices obtained from pricing services.

Additionally, the valuation of fixed maturities 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 the estimated fair value of an investment 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 June 30, 2013 , Level 3 assets represented five percent of assets that are measured at fair value and three percent of total assets. Level 3 liabilities represented 100 percent of liabilities that are measured at fair value and one percent of our total liabilities. During the three and six months ended June 30, 2013 , we transferred assets of $ 48 million and $63 million, respectively, into our Level 3 assets from other levels of the valuation hierarchy. During the three and six months ended June 30, 2013 , we transferred assets of $ 41 million and $71 million, respectively, 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, 2013 and 2012 .

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 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

71 

Table of Contents

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.

During the six months ended June 30, 2013 , no material changes were made to actuarial or behavioral assumptions.

During the three and six months ended June 30, 2013 , realized gains of $101 million and $470 million, respectively, were associated with a decreased value of GLB liabilities primarily due to rising equity levels and the favorable impact of foreign exchange and interest rate movements partially offset by the impact of discounting future claims for one and two fewer quarters, respectively. This excludes realized losses of $ 68 million and $318 million during the three and six months ended June 30, 2013 , respectively, on derivative hedge instruments held to partially offset the risk in the VA guarantee reinsurance portfolio. These derivatives do not receive hedge accounting treatment. Refer to the “Net Realized and Unrealized Gains (Losses)” section for a breakdown of the realized gains (losses) on GLB reinsurance and derivatives for the three and six months ended June 30, 2013 and 2012 .

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). The different categories of claim limits are described below:

•	Reinsurance programs covering guaranteed minimum death benefits (GMDB) with an annual claim limit of two percent of account value. This category accounts for approximately 60 percent of the total reinsured GMDB guaranteed value. Approximately one percent of the guaranteed value in this category has additional reinsurance coverage for GLB.	

•	Reinsurance programs covering GMDB with claim limit(s) that are a function of the underlying guaranteed value. This category accounts for approximately 25 percent of the total reinsured GMDB guaranteed value. The annual claim limit expressed as a percentage of guaranteed value ranges from 0.4 percent to 2 percent. Approximately 65 percent of guaranteed value in this category is also subject to annual claim deductibles that range from 0.1 percent to 0.2 percent of guaranteed value (i.e., our reinsurance coverage would only pay total annual claims in excess of 0.1 percent to 0.2 percent of the total guaranteed value). Approximately 50 percent of guaranteed value in this category is also subject to an aggregate claim limit which was approximately $ 382 million as of June 30, 2013 . Approximately 75 percent of guaranteed value in this category has additional reinsurance coverage for GLB.	

•	Reinsurance programs covering GMDB and guaranteed minimum accumulation benefits (GMAB). This category accounts for approximately 15 percent of the total reinsured GLB guaranteed value and 15 percent of the total reinsured GMDB guaranteed value. These reinsurance programs are quota-share agreements with the quota-share decreasing as the ratio of account value to guaranteed value decreases. The quota-share is 100 percent for ratios between 100 percent and 75 percent, 60 percent for additional losses on ratios between 75 percent and 45 percent, and 30 percent for further losses on ratios below 45 percent. Approximately 35 percent of guaranteed value in this category is also subject to a claim deductible of 8.8 percent of guaranteed value (i.e., our reinsurance coverage would only pay when the ratio of account value to guaranteed value is below 91.2 percent).	

•	Reinsurance programs covering GMIB with an annual claim limit. This category accounts for approximately 55 percent of the total reinsured GLB guaranteed value. The annual claim limit is 10 percent of guaranteed value on over 95 percent of the guaranteed value in this category. Additionally, reinsurance programs in this category have an annual annuitization limit that ranges between 17.5 percent and 30 percent with approximately 40 percent of guaranteed value subject to an annuitization limit of 20 percent or under, and the remaining 60 percent subject to an annuitization limit of 30 percent. Approximately 40 percent of guaranteed value in this category is also subject to minimum annuity conversion factors that	

72

Table of Contents

limit the exposure to low interest rates. Approximately 40 percent of guaranteed value in this category has additional reinsurance coverage for GMDB.

•	Reinsurance programs covering GMIB with aggregate claim limit. This category accounts for approximately 30 percent of the total reinsured GLB guaranteed value. The aggregate claim limit for reinsurance programs in this category is approximately $ 1.9 billion. Additionally, reinsurance programs in this category have an annual annuitization limit of 20 percent and approximately 60 percent of guaranteed value in this category is also subject to minimum annuity conversion factors that limit the exposure to low interest rates. Approximately 40 percent of guaranteed value in this category has additional reinsurance coverage for GMDB.	

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 asset of $ 39 million and $24 million at June 30, 2013 and December 31, 2012 , 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 through policyholder withdrawals, annuitizations, and deaths at a rate of 5 percent – 10 percent annually.

Note that GLB claims cannot occur for any reinsured policy until it has reached the end of its “waiting period”. The vast majority of policies we reinsure reach the end of their “waiting periods” in 2013 or later, as shown in the table below.

Death Benefits (GMDB)
For premiums and claims from VA contracts reinsuring GMDBs, at current market levels, we expect approximately $ 57 million of claims and $ 71 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. Approximately 80 percent of our living benefit reinsurance clients’ policyholders are currently ineligible to trigger a claim payment. The vast majority of these policyholders become eligible between years 2013 and 2018. At current market levels, we expect approximately $11 million of claims and $141 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 following modeled loss information reflects our in-force portfolio and reinsurance program at April 1, 2013.

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 U.S. hurricanes and California earthquakes at June 30, 2013 and 2012 . The table also presents ACE’s corresponding share of pre-tax industry losses for each of the return periods for U.S. hurricanes and California earthquakes at June 30, 2013 and 2012. 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 U.S. hurricanes could be in excess of $1,714 million (or 6.3 percent of our total shareholders’ equity at June 30, 2013 ). We estimate that at such hypothetical loss levels, ACE’s share of aggregate industry losses would be approximately one percent.

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) and consists of two separate towers.

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.

There were no significant changes to ACE's coverage under its North American Core Property Catastrophe Program during the second quarter.  However, with respect to our International Property Catastrophe Program, we renewed the layers of reinsurance protection in excess of $150 million on our Core Program for the period from July 1, 2013 through June 30, 2014. We expanded our all perils coverage from $250 million to $350 million (by expanding perils covered in what was historically the $300 million to $450 million layer) and eliminated the $500 million to $550 million layer of coverage. There is an additional $75 million global top layer that continues to sit above the International Property Catastrophe Program and the North American Core Program that expires at January 1st and now attaches at $500 million on our International Program. There were no other significant changes in coverage from the expiring program. Refer to our 2012 Form 10-K for additional information.

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.

Each year the RMA issues a final SRA for the subsequent reinsurance year. In June 2013, the RMA released the 2014 SRA which establishes the terms and conditions for the 2014 reinsurance year (i.e., July 1, 2013 through June 30, 2014) that replaced the 2013 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 ea rned over the growing season for the crops. A majority of the crops 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, 2013 , our available credit lines totaled $1.9 billion and usage to support issued letters of credit was $1.3 billion. Our access to funds under existing credit facilities is dependent on the ability of the banks that are parties to the facilities to meet their funding commitments. Our existing credit facilities have remaining terms expiring between 2014 and 2017 and require that we maintain certain financial covenants, all of which we met at June 30, 2013 . 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 2012 Form 10-K.

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, 2013 , 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 did not receive any dividends from its Bermuda subsidiaries during the six months ended June 30, 2013 and 2012 .

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 did not receive any dividends from AGM or ACE INA during the six months ended June 30, 2013 and 2012 . 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.

Cash Flows
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, 2013 and 2012 .

Our consolidated net cash flows from operating activities were $1.8 billion in the six months ended June 30, 2013, compared with $1.4 billion in the prior year period. The increase in operating cash flows was primarily due to higher net premiums collected of $187 million and lower income taxes paid of $171 million.

Our consolidated net cash flows used for investing activities were $2.4 billion in the six months ended June 30, 2013, compared with $1.3 billion in the prior year period. The increase in cash flows used for investing activities was primarily due to the acquisitions of ABA Seguros and Fianzas Monterrey in the second quarter 2013.

Our consolidated net cash flows from financing activities were $658 million in the six months ended June 30, 2013 , compared with net cash flows used for financing activities of $123 million in the prior year period. Financing cash flows for the six months ended June 30, 2013 included $947 million of proceeds from the issuance of long-term debt. Refer to Note 6 to the Consolidated Financial Statements for additional information on the long-term debt issuance. The prior year period financing cash flows included $151 million from the issuance of short-term debt, net of repayments. Share repurchases and dividends paid on Common Shares were $212 million and $169 million, respectively, in the six months ended June 30, 2013, compared with $11 million and $318 million, respectively. Dividends paid on Common Shares decreased 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 utilize 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. We subsequently settle these transactions with future operating cash flows. At June 30, 2013 , there were $1.4 billion in repurchase agreements outstanding.

Ratio of debt to total capitalization	17.1	%	 	14.6	%	
Ratio of debt plus trust preferred securities to total capitalization	18.1	%	 	15.6	%	

In June 2013, we reclassified $500 million of 5.875 percent senior notes, due to mature on June 15, 2014, from Long-term debt to Short-term debt in the consolidated balance sheet.

Our ratios of debt to total capitalization and debt plus trust preferred securities to total capitalization increased primarily due to the issuance of $ 475 million of 2.7 percent senior notes due March 2023 and $ 475 million of 4.15 percent senior notes due March 2043 during the six months ended June 30, 2013 . The proceeds from the debt issuance are expected to be used to repay at maturity the $500 million 5.875 percent senior notes due June 2014 and the $450 million 5.6 percent senior notes due May 2015.

The following table reports the significant movements in our shareholders’ equity:

Repurchase of shares	(212	)	
Exercise of stock options	54		
Other movements, net of tax	59		
Balance – end of period	$	27,295		

During the six months ended June 30, 2013 , we repurchased $212 million of Common Shares in a series of open market transactions under the November 2012, August 2011 and November 2010 Board of Directors authorizations, primarily to offset dilution from our incentive compensation plans. At June 30, 2013 , $249 million in share repurchase authorizations remained through December 31, 2013. At June 30, 2013 there were 2,746,143 Common Shares in treasury with a weighted average cost of $79.57 per share.

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.

Dividends
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. Following ACE’s redomestication to Switzerland in July 2008 through March 2011, dividends were distributed by way of a par value reduction. At our May 2011 annual general meeting, our shareholders approved dividend distributions from capital contribution reserves (Additional paid-in capital) through the transfer of dividends from Additional paid-in capital to Retained earnings. At our May 2012 annual general meeting, our shareholders approved an annual dividend distribution for the following year by way of a par value reduction equal to $1.96 per share, or CHF 1.80 per share, calculated using the USD/CHF exchange rate as published in the Wall Street Journal on May 10, 2012. 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 is payable in four quarterly installments, with each installment equaling $ 0.51 per share, provided that the Swiss franc equivalent of that amount per share (based on the then-current USD/CHF exchange rate), taken together with the Swiss franc equivalents of all other installments of this annual dividend, will not exceed 150 percent of CHF 1.92 (the aggregate distribution cap). If the Swiss franc equivalent of an upcoming dividend installment would cause the aggregate distribution cap to be exceeded, then that dividend installment will be reduced to equal the Swiss franc amount remaining available under the aggregate distribution cap, and the U.S. dollar amount distributed for that installment will be the then-applicable U.S. dollar equivalent of the remaining Swiss franc amount.

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:	  	 	
March 28, 2013	  	April 12, 2013	  	$0.49 (CHF 0.46)	
July 23, 2013	  	August 13, 2013	  	$0.51 (CHF 0.48)	

ITEM 3. Quantitative and Qualitative Disclosures about Market Risk
Refer to Item 7A included in our 2012 Form 10-K.

Reinsurance of GMDB and GLB guarantees
Our net income is directly impacted by changes in the benefit reserves calculated in connection with the reinsurance of variable annuity guarantees, primarily GMDB and GLB. The benefit reserves are calculated in accordance with the 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. In addition, our 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, 2013 , 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 average growth over the next several years. Management regularly examines both quantitative and qualitative analysis and for the quarter ended June 30, 2013 , determined that no change to the benefit ratio was warranted. The benefit ratio used to

78

Table of Contents

establish the benefit reserves at June 30, 2013 , has averaged less than 1/4 standard deviation from the calculated benefit ratios, averaging the periodic results from a 2 -year rolling period ending June 30, 2013 .

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 the assumptions underlying the benefit ratio calculation used to establish benefit reserves should be adjusted. The benefit ratio will be 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. The differential is measured in terms of the standard deviation of the distribution of benefit ratios (reflecting 1,000 stochastic scenarios) calculated on subsequent dates.

The 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 the benefit reserves at June 30, 2013 and show the sensitivity, at June 30, 2013 , 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, 2013 ). 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 $25 million to $55 million increase in Gross FVL and realized losses. However, the impact to Net income is substantially mitigated because the majority of this realized loss is offset 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: 5 percent— 15 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 60 percent— 70 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

80

Table of Contents

sensitivity is from June 30, 2013 market levels and includes the impact of an adjustment to the hedge portfolio made subsequent to that date.

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, 2013 following an immediate change in equity market levels, assuming all global equity markets are impacted equall y. 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

																								
 	Equity Shock	
(in millions of U.S. dollars, except percentages)	+20%	 	Flat	 	-20%	 	-40%	 	-60%	 	-80%	
GMDB net amount at risk	$	574		 	$	884		 	$	1,548		 	$	2,010		 	$	1,977		 	$	1,684		
Claims at 100% immediate mortality	745		 	563		 	341		 	296		 	265		 	239		

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

																								
 	Equity Shock	
(in millions of U.S. dollars, except percentages)	+20%	 	Flat	 	-20%	 	-40%	 	-60%	 	-80%	
GLB net amount at risk	$	86		 	$	302		 	$	935		 	$	1,791		 	$	2,500		 	$	2,702		

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

																								
 	Equity Shock	
(in millions of U.S. dollars, except percentages)	+20%	 	Flat	 	-20%	 	-40%	 	-60%	 	-80%	
GMDB net amount at risk	$	62		 	$	95		 	$	136		 	$	176		 	$	210		 	$	245		
GLB net amount at risk	107		 	341		 	836		 	1,479		 	2,068		 	2,427		
Claims at 100% immediate mortality	75		 	300		 	635		 	870		 	1,077		 	1,252		

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.

ITEM 4. Controls and Procedures
ACE’s management, with the participation of ACE’s Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of ACE’s disclosure controls and procedures as defined in Rule 13a-15(e) and Rule 15d-15(e) under the Securities Exchange Act of 1934 as of June 30, 2013 . Based upon that evaluation, ACE’s Chief Executive Officer and Chief Financial Officer concluded that ACE’s disclosure controls and procedures are effective in allowing information required to be disclosed in reports filed under the Securities and Exchange Act of 1934 to be recorded, processed, summarized and reported within time periods specified in the rules and forms of the SEC, and that such information is accumulated and communicated to ACE’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

There has been no change in ACE’s internal controls over financial reporting during the three months ended June 30, 2013 that has materially affected, or is reasonably likely to materially affect, ACE’s internal controls over financial reporting.
