Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Summary of significant accounting policies | Summary of significant accounting policies a) Basis of presentation Chubb Limited is a holding company incorporated in Zurich, Switzerland. Chubb Limited, through its subsidiaries, provides a broad range of insurance and reinsurance products to insureds worldwide. Our results are reported through the following business segments: North America Commercial P&C Insurance, North America Personal P&C Insurance, North America Agricultural Insurance, Overseas General Insurance, Global Reinsurance, and Life Insurance. Refer to Note 15 for additional information. The accompanying consolidated financial statements, which include the accounts of Chubb Limited and its subsidiaries (collectively, Chubb, 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, including internal reinsurance transactions, have been eliminated. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Amounts included in the Consolidated financial statements reflect our best estimates and assumptions; actual amounts could differ materially from these estimates. Chubb's principal estimates include: • unpaid loss and loss expense reserves, including long-tail asbestos and environmental (A&E) reserves; • future policy benefits reserves; • the valuation of value of business acquired (VOBA) and amortization of deferred policy acquisition costs and VOBA; • reinsurance recoverable, including a provision for uncollectible reinsurance; • the assessment of risk transfer for certain structured insurance and reinsurance contracts; • the valuation of the investment portfolio and assessment of OTTI; • the valuation of deferred tax assets; • the valuation of derivative instruments related to guaranteed living benefits (GLB); • the valuation and amortization of purchased intangibles; and • the assessment of goodwill for impairment. b) Premiums Premiums are generally recorded as written upon inception of the policy. For multi-year policies for which premiums written are payable in annual installments, only the current annual premium is included as written at policy inception due to the ability of the insured/reinsured to commute or cancel coverage within the policy term. The remaining annual premiums are recorded as written at each successive anniversary date within the multi-year term. For P&C insurance and reinsurance products, premiums written are primarily earned on a pro-rata basis over the policy terms to which they relate. Unearned premiums represent the portion of premiums written applicable to the unexpired portion of the policies in force. For retrospectively-rated policies, written premiums are adjusted to reflect expected ultimate premiums consistent with changes to incurred losses, or other measures of exposure as stated in the policy, and earned over the policy coverage period. For retrospectively-rated multi-year policies, premiums recognized in the current period are computed using a with-and-without method as the difference between the ceding enterprise's total contract costs before and after the experience under the contract at the reporting date. Accordingly, for retrospectively-rated multi-year policies, additional premiums are generally written and earned when losses are incurred. Mandatory reinstatement premiums assessed on reinsurance policies are earned in the period of the loss event that gave rise to the reinstatement premiums. All remaining unearned premiums are recognized over the remaining coverage period. Premiums from long-duration contracts such as certain traditional term life, whole life, endowment, and long-duration personal accident and health (A&H) policies are generally recognized as revenue when due from policyholders. Traditional life policies include those contracts with fixed and guaranteed premiums and benefits. Benefits and expenses are matched with income to result in the recognition of profit over the life of the contracts. Retroactive loss portfolio transfer (LPT) contracts in which the insured loss events occurred prior to contract inception are evaluated to determine whether they meet criteria for reinsurance accounting. If reinsurance accounting is appropriate, written premiums are fully earned and corresponding losses and loss expenses recognized at contract inception. These contracts can cause significant variances in gross premiums written, net premiums written, net premiums earned, and net incurred losses in the years in which they are written. Reinsurance contracts sold not meeting criteria for reinsurance accounting are recorded using the deposit method as described below in Note 1 k). Reinsurance premiums assumed are based on information provided by ceding companies supplemented by our own estimates of premium when we have not received ceding company reports. Estimates are reviewed and adjustments are recorded in the period in which they are determined. Premiums are earned over the coverage terms of the related reinsurance contracts and range from one to three years. c) Deferred policy acquisition costs and value of business acquired Policy acquisition costs consist of commissions (direct and ceded), premium taxes, and certain underwriting costs related directly to the successful acquisition of new or renewal insurance contracts. A VOBA intangible asset is established upon the acquisition of blocks of long-duration contracts in a business combination and represents the present value of estimated net cash flows for the contracts in force at the acquisition date. Acquisition costs and VOBA, collectively policy acquisition costs, are deferred and amortized. Amortization is recorded in Policy acquisition costs in the Consolidated statements of operations. Policy acquisition costs on P&C contracts are generally amortized ratably over the period in which premiums are earned. Policy acquisition costs on traditional long-duration contracts are amortized over the estimated life of the contracts, generally in proportion to premium revenue recognized based upon the same assumptions used in estimating the liability for future policy benefits. For non-traditional long-duration contracts, we amortize policy acquisition costs over the expected life of the contracts in proportion to expected gross profits. The effect of changes in estimates of expected gross profits is reflected in the period the estimates are revised. Policy acquisition costs are reviewed to determine if they are recoverable from future income, including investment income. Unrecoverable policy acquisition costs are expensed in the period identified. Advertising costs are expensed as incurred except for direct-response campaigns that qualify for cost deferral, principally related to long-duration A&H business produced by the Overseas General Insurance segment, which are deferred and recognized as a component of Policy acquisition costs . For individual direct-response marketing campaigns that we can demonstrate have specifically resulted in incremental sales to customers and such sales have probable future economic benefits, incremental costs directly related to the marketing campaigns are capitalized as Deferred policy acquisition costs. Deferred policy acquisition costs, including deferred marketing costs, are reviewed regularly for recoverability from future income, including investment income, and amortized in proportion to premium revenue recognized, primarily over a ten -year period, the expected economic future benefit period based upon the same assumptions used in estimating the liability for future policy benefits. The expected future benefit period is evaluated periodically based on historical results and adjusted prospectively. The amount of deferred marketing costs reported in Deferred policy acquisition costs in the Consolidated balance sheets was $ 271 million and $ 256 million at December 31, 2017 and 2016 , respectively. Amortization expense for deferred marketing costs was $ 116 million, $ 92 million, and $ 78 million for the years ended December 31, 2017 , 2016 , and 2015 , respectively. d) Reinsurance Chubb assumes and cedes reinsurance with other insurance companies to provide greater diversification of business and minimize the net loss potential arising from large risks. Ceded reinsurance contracts do not relieve Chubb of its primary obligation to policyholders. For both ceded and assumed reinsurance, risk transfer requirements must be met in order to account for a contract as reinsurance, principally resulting in the recognition of cash flows under the contract as premiums and losses. To meet risk transfer requirements, a reinsurance contract must include insurance risk, consisting of both underwriting and timing risk, and a reasonable possibility of a significant loss for the assuming entity. To assess risk transfer for certain contracts, Chubb generally develops expected discounted cash flow analyses at contract inception. Deposit accounting is used for contracts that do not meet risk transfer requirements. Deposit accounting requires that consideration received or paid be recorded in the balance sheet as opposed to recording premiums written or losses incurred in the statement of operations. Non-refundable fees on deposit contracts are earned based on the terms of the contract described below in Note 1 k). Reinsurance recoverable includes balances due from reinsurance companies for paid and unpaid losses and loss expenses and future policy benefits that will be recovered from reinsurers, based on contracts in force. The method for determining the reinsurance recoverable on unpaid losses and loss expenses incurred but not reported (IBNR) involves actuarial estimates consistent with those used to establish the associated liability for unpaid losses and loss expenses as well as a determination of Chubb's ability to cede unpaid losses and loss expenses under the terms of the reinsurance agreement. Reinsurance recoverable is presented net of a provision for uncollectible reinsurance determined based upon a review of the financial condition of reinsurers and other factors. The provision for uncollectible reinsurance is based on an estimate of the reinsurance recoverable balance that will ultimately be unrecoverable due to reinsurer insolvency, a contractual dispute, or any other reason. The valuation of this provision includes several judgments including certain aspects of the allocation of reinsurance recoverable on IBNR claims by reinsurer and a default analysis to estimate uncollectible reinsurance. The primary components of the default analysis are reinsurance recoverable balances by reinsurer, net of collateral, and default factors used to determine the portion of a reinsurer's balance deemed uncollectible. The definition of collateral for this purpose requires some judgment and is generally limited to assets held in a Chubb-only beneficiary trust, letters of credit, and liabilities held with the same legal entity for which Chubb believes there is a contractual right of offset. The determination of the default factor is principally based on the financial strength rating of the reinsurer. Default factors require considerable judgment and are determined using the current financial strength rating, or rating equivalent, of each reinsurer as well as other key considerations and assumptions. The more significant considerations include, but are not necessarily limited to, the following: • For reinsurers that maintain a financial strength rating from a major rating agency, and for which recoverable balances are considered representative of the larger population (i.e., default probabilities are consistent with similarly rated reinsurers and payment durations conform to averages), the financial rating is based on a published source and the default factor is based on published default statistics of a major rating agency applicable to the reinsurer's particular rating class. When a recoverable is expected to be paid in a brief period of time by a highly rated reinsurer, such as certain property catastrophe claims, a default factor may not be applied; • For balances recoverable from reinsurers that are both unrated by a major rating agency and for which management is unable to determine a credible rating equivalent based on a parent, affiliate, or peer company, we determine a rating equivalent based on an analysis of the reinsurer that considers an assessment of the creditworthiness of the particular entity, industry benchmarks, or other factors as considered appropriate. We then apply the applicable default factor for that rating class. For balances recoverable from unrated reinsurers for which the ceded reserve is below a certain threshold, we generally apply a default factor of 34 percent, consistent with published statistics of a major rating agency; • For balances recoverable from reinsurers that are either insolvent or under regulatory supervision, we establish a default factor and resulting provision for uncollectible reinsurance based on reinsurer-specific facts and circumstances. Upon initial notification of an insolvency, we generally recognize an expense for a substantial portion of all balances outstanding, net of collateral, through a combination of write-offs of recoverable balances and increases to the provision for uncollectible reinsurance. When regulatory action is taken on a reinsurer, we generally recognize a default factor by estimating an expected recovery on all balances outstanding, net of collateral. When sufficient credible information becomes available, we adjust the provision for uncollectible reinsurance by establishing a default factor pursuant to information received; and • For other recoverables, management determines the provision for uncollectible reinsurance based on the specific facts and circumstances. The methods used to determine the reinsurance recoverable balance and related provision for uncollectible reinsurance are regularly reviewed and updated, and any resulting adjustments are reflected in earnings in the period identified. Prepaid reinsurance premiums represent the portion of premiums ceded to reinsurers applicable to the unexpired coverage terms of the reinsurance contracts in-force. The value of reinsurance business assumed of $ 18 million and $ 20 million at December 31, 2017 and 2016 , respectively, included in Other assets in the accompanying Consolidated balance sheets, represents the excess of estimated ultimate value of the liabilities assumed under retroactive reinsurance contracts over consideration received. The value of reinsurance business assumed is amortized and recorded to Losses and loss expenses based on the payment pattern of the losses assumed and ranges between 9 and 40 years. The unamortized value is reviewed regularly to determine if it is recoverable based upon the terms of the contract, estimated losses and loss expenses, and anticipated investment income. Unrecoverable amounts are expensed in the period identified. e) Investments Fixed maturities are classified as either available for sale or held to maturity. The available for sale portfolio is reported at fair value. The held to maturity portfolio includes securities for which we have the ability and intent to hold to maturity or redemption and is reported at amortized cost. Equity securities are classified as available for sale and are recorded at fair value. Short-term investments comprise securities due to mature within one year of the date of purchase and are recorded at fair value which typically approximates cost. Short-term investments include certain cash and cash equivalents, which are part of investment portfolios under the management of external investment managers. Other investments principally comprise life insurance policies, policy loans, trading securities, other direct equity investments, investment funds, and limited partnerships. • Life insurance policies are carried at policy cash surrender value and income is recorded in Other income (expense). • Policy loans are carried at outstanding balance and interest income is recorded to Net investment income. • Trading securities are recorded on a trade date basis and carried at fair value. Unrealized gains and losses on trading securities are reflected in Other (income) expense. • Other investments over which Chubb can exercise significant influence are accounted for using the equity method and income is recorded in Other (income) expense. • All other investments over which Chubb cannot exercise significant influence are carried at fair value with changes in fair value recognized through OCI. For these investments, investment income is recognized in Net investment income and realized gains are recognized as related distributions are received. • Partially-owned investment companies comprise entities in which we hold an ownership interest in excess of three percent. These investments as well as Chubb's investments in investment funds where our ownership interest is in excess of three percent are accounted for under the equity method because Chubb exerts significant influence. These investments apply investment company accounting to determine operating results, and Chubb retains the investment company accounting in applying the equity method. This means that investment income, realized gains or losses, and unrealized gains or losses are included in the portion of equity earnings reflected in Other (income) expense. As a result of the timing of the receipt of valuation data from the investment managers, these investments are generally reported on a three month lag. Investments in partially-owned insurance companies primarily represent direct investments in which Chubb has significant influence and, as such, meet the requirements for equity accounting. We report our share of the net income or loss of the partially-owned insurance companies in Other (income) expense. Realized gains or losses on sales of investments are determined on a first-in, first-out basis. Unrealized appreciation (depreciation) on investments is included as a separate component of AOCI in Shareholders' equity. We regularly review our investments for OTTI. Refer to Note 3 for additional information. With respect to securities where the decline in value is determined to be temporary and the security's value is not written down, a subsequent decision may be made to sell that security and realize a loss. Subsequent decisions on security sales are the result of changing or unforeseen facts and circumstances (i.e., arising from a large insured loss such as a catastrophe), deterioration of the creditworthiness of the issuer or its industry, or changes in regulatory requirements. We believe that subsequent decisions to sell such securities are consistent with the classification of the majority of the portfolio as available for sale. We use derivative instruments including futures, options, swaps, and foreign currency forward contracts for the purpose of managing certain investment portfolio risks and exposures. Refer to Note 10 for additional information. Derivatives are reported at fair value and are recorded in the accompanying Consolidated balance sheets in either Accounts payable, accrued expenses, and other liabilities or Other assets with changes in fair value included in Net realized gains (losses) in the Consolidated statements of operations. Collateral held by brokers equal to a percentage of the total value of open futures contracts is included in the investment portfolio. Net investment income includes interest and dividend income and amortization of fixed maturity market premiums and discounts and is net of investment management and custody fees. In addition, net investment income includes the amortization of the fair value adjustment related to the acquired invested assets of Chubb Corp. An adjustment of $1,652 million related to the fair value of Chubb Corp’s fixed maturities securities was recorded (fair value adjustment) at the date of acquisition. At December 31, 2017, the remaining balance of this fair value adjustment was $858 million which is expected to amortize over the next four years; however, the estimate could vary materially based on current market conditions, bond calls, and the duration of the acquired investment portfolio. In addition, sales of these acquired fixed maturities would also reduce the fair value adjustment balance. For mortgage-backed securities, and any other holdings for which there is a prepayment risk, prepayment assumptions are evaluated and revised as necessary. Any adjustments required due to the resultant change in effective yields and maturities are recognized prospectively. Prepayment fees or call premiums that are only payable when a security is called prior to its maturity are earned when received and reflected in Net investment income. Chubb participates in a securities lending program operated by a third-party banking institution whereby certain assets are loaned to qualified borrowers and from which we earn an incremental return. Borrowers provide collateral, in the form of either cash or approved securities, of 102 percent of the fair value of the loaned securities. Each security loan is deemed to be an overnight transaction. Cash collateral is invested in a collateral pool which is managed by the banking institution. The collateral pool is subject to written investment guidelines with key objectives which include the safeguard of principal and adequate liquidity to meet anticipated redemptions. The fair value of the loaned securities is monitored on a daily basis, with additional collateral obtained or refunded as the fair value of the loaned securities changes. The collateral is held by the third-party banking institution, and the collateral can only be accessed in the event that the institution borrowing the securities is in default under the lending agreement. As a result of these restrictions, we consider our securities lending activities to be non-cash investing and financing activities. 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. The fair value of the securities on loan is included in fixed maturities and equity securities. The securities lending collateral is reported as a separate line in the Consolidated balance sheets with a related liability reflecting our obligation to return the collateral plus interest. Similar to securities lending arrangements, securities sold under repurchase agreements, whereby Chubb sells securities and repurchases them at a future date for a predetermined price, are accounted for as collateralized investments and borrowings and are recorded at the contractual repurchase amounts plus accrued interest. Assets to be repurchased are the same, or substantially the same, as the assets transferred and the transferor, through right of substitution, maintains the right and ability to redeem the collateral on short notice. The fair value of the underlying securities is included in fixed maturities and equity securities. In contrast to securities lending programs, the use of cash received is not restricted. We report the obligation to return the cash as Repurchase agreements in the Consolidated balance sheets. Refer to Note 4 for a discussion on the determination of fair value for Chubb's various investment securities. f) Cash Cash includes cash on hand and deposits with an original maturity of three months or less at time of purchase. Cash held by external money managers is included in Short-term investments. We have agreements with a third-party bank provider which implemented two international multi-currency notional cash pooling programs. In each program, participating Chubb entities establish deposit accounts in different currencies with the bank provider and each day the credit or debit balances in every account are notionally translated into a single currency (U.S. dollars) and then notionally pooled. The bank extends overdraft credit to any participating Chubb entity as needed, provided that the overall notionally-pooled balance of all accounts in each pool at the end of each day is at least zero. Actual cash balances are not physically converted and are not commingled between legal entities. Any overdraft balances incurred under this program by a Chubb entity would be guaranteed by Chubb Limited (up to $ 300 million in the aggregate). Our syndicated letter of credit facility allows for same day drawings to fund a net pool overdraft should participating Chubb entities overdraw contributed funds from the pool. g) Goodwill and Other intangible assets Goodwill represents the excess of the cost of acquisitions over the fair value of net assets acquired and is not amortized. Goodwill is assigned at acquisition to the applicable reporting unit of the acquired entities giving rise to the goodwill. Goodwill impairment tests are performed annually or more frequently if circumstances indicate a possible impairment. For goodwill impairment testing, we use a qualitative assessment to determine whether it is more likely than not (i.e., more than a 50 percent probability) that the fair value of a reporting unit is greater than its carrying amount. If our assessment indicates less than a 50 percent probability that fair value exceeds carrying value, we quantitatively estimate a reporting unit's fair value. Goodwill recorded in connection with investments in partially-owned insurance companies is recorded in Investments in partially-owned insurance companies and is also measured for impairment annually. Indefinite lived intangible assets are not subject to amortization. Finite lived intangible assets are amortized over their useful lives, generally ranging from 1 to 30 years. Intangible assets are regularly reviewed for indicators of impairment. Impairment is recognized if the carrying amount is not recoverable from its undiscounted cash flows and is measured as the difference between the carrying amount and fair value. h) Unpaid losses and loss expenses A liability is established for the estimated unpaid losses and loss expenses under the terms of, and with respect to, Chubb's policies and agreements. Similar to premiums that are recognized as revenues over the coverage period of the policy, a liability for unpaid losses and loss expenses is recognized as expense when insured events occur over the coverage period of the policy. This liability includes a provision for both reported claims (case reserves) and incurred but not reported claims (IBNR reserves). IBNR reserve estimates are generally calculated by first projecting the ultimate cost of all losses that have occurred (expected losses), and then subtracting paid losses, case reserves, and loss expenses. The methods of determining such estimates and establishing the resulting liability are reviewed regularly and any adjustments are reflected in operations in the period in which they become known. Future developments may result in losses and loss expenses materially greater or less than recorded amounts. Except for net loss and loss expense reserves of $ 36 million net of discount, held at December 31, 2017 , representing certain structured settlements for which the timing and amount of future claim payments are reliably determinable and $ 41 million, net of discount, of certain reserves for unsettled claims that are discounted in statutory filings, Chubb does not discount its P&C loss reserves. This compares with reserves of $ 38 million for certain structured settlements and $ 50 million of certain reserves for unsettled claims at December 31, 2016 . Structured settlements represent contracts purchased from life insurance companies primarily to settle workers' compensation claims, where payments to the claimant by the life insurance company are expected to be made in the form of an annuity. Chubb retains the liability to the claimant in the event that the life insurance company fails to pay. At December 31, 2017 , the liability due to claimants was $ 586 million, net of discount, and reinsurance recoverables due from the life insurance companies was $ 550 million, net of discount. For structured settlement contracts where payments are guaranteed regardless of claimant life expectancy, the amounts recoverable from the life insurance companies at December 31, 2017 are included in Other assets in the Consolidated balance sheets, as they do not meet the requirements for reinsurance accounting. Included in Unpaid losses and loss expenses are liabilities for asbestos and environmental (A&E) claims and expenses. These unpaid losses and loss expenses are principally related to claims arising from remediation costs associated with hazardous waste sites and bodily-injury claims related to asbestos products and environmental hazards. The estimation of these liabilities is particularly sensitive to changes in the legal environment including specific settlements that may be used as precedents to settle future claims. However, Chubb does not anticipate future changes in laws and regulations in setting its A&E reserve levels. Also included in Unpaid losses and loss expenses is a fair value adjustment of $ 309 million at December 31, 2017 related to Chubb Corp’s historical unpaid losses and loss expenses. The estimated fair value consists of the present value of the expected net unpaid loss and loss adjustment expense payments adjusted for an estimated risk margin. The estimated cash flows are discounted at a risk free rate. The estimated risk margin varies based on the inherent risks associated with each type of reserve. The fair value is amortized through Amortization of purchased intangibles on the consolidated statements of operations over a range of 5 to 17 years, based on the estimated payout patterns of unpaid loss and loss expenses at the acquisition date. 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 premiums from previous accident years. For purposes of analysis and disclosure, management views prior period development to be changes in the nominal value of loss estimates from period to period, net of premium and profit commission adjustments on loss sensitive contracts. Prior period development generally excludes changes in loss estimates that do not arise from the emergence of claims, such as those related to uncollectible reinsurance, interest, unallocated loss adjustment expenses, or foreign currency. Accordingly, specific items excluded from prior period development include the following: gains/losses related to foreign currency remeasurement; losses recognized from the early termination or commutation of reinsurance agreements that principally relate to the time value of money; changes in the value of reinsurance business assumed reflected in losses incurred but principally related to the time value of money; and losses that arise from changes in estimates of earned premiums from prior accident years. Except for foreign currency remeasurement, which is included in Net realized gains (losses), these items are included in current year losses. i) Future policy benefits The valuation of long-duration contract reserves requires management to make estimates and assumptions regarding expenses, mortality, persistency, and investment yields. Estimates are primarily based on historical experience and information provided by ceding companies and include a margin for adverse deviation. Interest rates used in calculating reserves range from less than 1.0 percent to 8.0 percent at both December 31, 2017 and 2016 . Actual results could differ materially from these estimates. Management monitors actual experience and where circumstances warrant, will revise assumptions and the related reserve estimates. Revisions are recorded in the period they are determined. Certain of our long-duration contracts are supported by assets that do not qualify for separate account reporting under GAAP. These assets are classifi |

Acquisitions | Acquisitions The Chubb Corporation (Chubb Corp) On January 14, 2016, we completed the acquisition of Chubb Corp, a leading provider of middle-market commercial, specialty, surety, and personal insurance for $ 29.5 billion , comprising $ 14.3 billion in cash and $ 15.2 billion in newly-issued stock. In addition, we assumed outstanding equity awards to employees and directors with an attributed value of $ 323 million . The total consideration, including the assumption of equity awards, was $29.8 billion . We recognized goodwill of $ 10.5 billion , attributable to expected growth and profitability, none of which is expected to be deductible for income tax purposes. We financed the cash portion of the transaction through a combination of $ 9.0 billion sourced from various Chubb Limited and Chubb Corp companies plus $ 5.3 billion of senior notes, which were issued in November 2015. Refer to Note 9 for additional information on the senior notes. Upon completion of the merger, each Chubb Corp common share (other than shares held by certain legacy Chubb Corp employee benefit plans) was canceled and converted, in accordance with the procedures set forth in the merger agreement, into the right to receive (i) 0.6019 of a Chubb Limited common share and (ii) $62.93 in cash. In addition, replacement equity awards were issued by Chubb Limited to the holders of Chubb Corp's outstanding equity awards (stock options, restricted stock units, deferred stock units, deferred unit obligations, and performance units). We believe the Chubb Corp acquisition is highly complementary to our existing business lines, distribution channels, customer segments, and underwriting skills. Chubb Corp has a substantial presence in the U.S. with a broad variety of coverages serving large corporate and upper middle market accounts, middle market and small commercial accounts, and personal lines. Together we are one of the largest commercial insurers in the U.S. Internationally, where legacy ACE is a truly global insurer with extensive presence in 54 countries and territories, Chubb Corp's operations in 25 markets added to our presence and capabilities and positioned us to better pursue important market opportunities globally. The combined company is a leader in a number of global specialty and traditional products such as professional lines, risk management, workers' compensation, accident and health (A&H), and other property and general casualty lines. The table below details the purchase consideration and allocation of assets acquired and liabilities assumed: (in millions of U.S. dollars, except per share data) Purchase consideration Chubb Limited common shares Chubb Corp common shares outstanding 228 Per share exchange ratio 0.6019 Common shares issued by Chubb Limited 137 Common share price of Chubb Limited at January 14, 2016 $ 111.02 Fair value of common shares issued by Chubb Limited to common shareholders of Chubb Corp $ 15,204 Cash consideration Chubb Corp common shares outstanding 228 Agreed cash price per share paid to common shareholders of Chubb Corp $ 62.93 Cash consideration paid by Chubb Limited to common shareholders of Chubb Corp $ 14,319 Stock-based awards Fair value of equity awards issued (1) $ 323 Fair value of purchase consideration $ 29,846 Assets acquired and (liabilities) assumed Cash $ 71 Investments 42,967 Accrued investment income 359 Insurance and reinsurance balances receivable 3,095 Reinsurance recoverable on losses and loss expenses 1,676 Indefinite lived intangible assets 2,860 Finite lived intangible assets 4,795 Prepaid reinsurance premiums 280 Other assets 853 Unpaid losses and loss expenses (22,923 ) Unearned premiums (7,011 ) Insurance and reinsurance balances payable (603 ) Accounts payable, accrued expenses, and other liabilities (2,030 ) Deferred tax liabilities (1,292 ) Long-term debt (3,765 ) Total identifiable net assets acquired 19,332 Goodwill 10,514 Purchase price $ 29,846 (1) The fair value of the replacement equity awards was $525 million , of which $323 million was attributed to service periods prior to the acquisition and was included in the purchase consideration. Refer to Note 12 for further information on these replacement equity awards. The purchase price allocation to intangible assets recorded in connection with the Chubb Corp acquisition and their related useful lives are as follows: (in millions of U.S. dollars) Purchase price Allocation at January 14, 2016 Estimated useful life Definite life Unearned premium reserves (UPR) intangible asset $ 1,550 1 year Agency distribution relationships and renewal rights 3,150 24 years Internally developed technology 95 3 years Indefinite life Trademarks 2,800 Indefinite Licenses 50 Indefinite Syndicate capacity 10 Indefinite Total identified intangible assets $ 7,655 Refer to Note 6 for additional information on goodwill and intangible assets acquired. The following table summarizes the results of the acquired Chubb Corp operations since the acquisition date that have been included within our Consolidated statement of operations: (in millions of U.S. dollars) January 14, 2016 to December 31, 2016 Total revenues $ 12,376 Net income $ 1,756 The following table provides supplemental unaudited pro forma consolidated information for the years ended December 31, 2016 and 2015, as if Chubb Corp had been acquired as of January 1, 2015. The unaudited pro forma consolidated financial statements are presented solely for informational purposes and are not necessarily indicative of the consolidated results of operations that might have been achieved had the transaction been completed as of the date indicated, nor are they meant to be indicative of any anticipated consolidated future results of operations that the combined company will experience after the transaction. Year Ended December 31 (in millions of U.S. dollars, except per share data) 2016 2015 Total revenues $ 31,937 $ 32,622 Net income $ 4,183 $ 4,478 Earnings per share Basic earnings per share $ 8.95 $ 9.61 Diluted earnings per share $ 8.88 $ 9.52 Total revenues and net income were lower for the year ended December 31, 2016, compared to the prior year, primarily reflecting merger-related actions in 2016, which lowered net premiums earned. Fireman's Fund Insurance Company High Net Worth Personal Lines Insurance Business in the U.S. (Fireman's Fund) On April 1, 2015, we acquired the Fireman's Fund Insurance Company high net worth personal lines insurance business in the U.S., which included the renewal rights for new and existing business and reinsurance of all existing reserves for $365 million in cash. We acquired assets with a fair value of $753 million , consisting primarily of cash of $629 million and insurance and reinsurance balances receivable of $124 million . We assumed liabilities with a fair value of $863 million , consisting primarily of unpaid losses and loss expenses of $417 million and unearned premiums of $428 million . This acquisition generated $196 million of goodwill, attributable to expected growth and profitability, all of which is expected to be deductible for income tax purposes, and other intangible assets of $278 million , primarily related to renewal rights, based on Chubb’s purchase price allocation. The acquisition expanded our position in the high net worth personal lines insurers in the U.S. The Fireman’s Fund business was integrated into our existing high net worth personal lines business, offering a broad range of coverage including homeowners, automobile, umbrella and excess liability, collectibles, and yachts. Goodwill and other intangible assets arising from this acquisition are included in our North America Personal P&C Insurance segment. The Consolidated financial statements include results of acquired businesses from the acquisition dates. |

Investments | Investments a) Transfers of securities During December 2017, we transferred securities, considered essential holdings in a diversified portfolio, with a total fair value of $4.3 billion from Fixed maturities available for sale to Fixed maturities held to maturity. These securities, which we have the intent and ability to hold to maturity, were transferred given the growth in our investment portfolio over the last several years, as well as continued efforts to manage the diversification of our global portfolio. The net unrealized appreciation at the date of the transfer continues to be reported in the carrying value of the transferred investments and is amortized through OCI over the remaining life of the securities using the effective interest method in a manner consistent with the amortization of any premium or discount.

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 Net unrealized appreciation on investments in the Consolidated statements of shareholders' equity. For the years ended December 31, 2017 and 2016 , $ 2 million of net unrealized depreciation and $ 62 million of net unrealized appreciation, respectively, related to such securities is included in OCI. At December 31, 2017 and 2016 , AOCI included cumulative net unrealized appreciation of $ 7 million and $ 10 million, respectively, related to securities remaining in the investment portfolio for which a non-credit OTTI was recognized. Mortgage-backed securities (MBS) issued by U.S. government agencies are combined with all other to be announced mortgage derivatives held (refer to Note 10 c) (iv)) and are included in the category, “Mortgage-backed securities”. Approximately 83 percent and 81 percent of the total mortgage-backed securities at December 31, 2017 and 2016 , respectively, 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.

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, we must evaluate the security to determine the portion of the impairment, if any, related to credit losses. If a credit loss is incurred, 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 • our ability and intent to hold the security to the expected recovery period. As a general rule, we also consider that equity securities in an unrealized loss position for twelve consecutive months are other than temporarily impaired. For mutual funds included in equity securities in our Consolidated balance sheets, we employ analysis similar to fixed maturities, when applicable. Evaluation of potential credit losses related to fixed maturities 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. U.S. Treasury and agency obligations (including agency mortgage-backed securities); foreign government obligations; and states, municipalities, and political subdivisions obligations U.S. Treasury and agency obligations (including agency mortgage-backed securities); foreign government obligations; and states, municipalities, and political subdivisions obligations represent $ 311 million of gross unrealized loss at December 31, 2017 . These securities were evaluated for credit loss primarily using qualitative assessments of the likelihood of credit loss considering credit rating of the issuers and level of credit enhancement, if any. We concluded that the high level of creditworthiness of the issuers coupled with credit enhancement, where applicable, supports recognizing no credit loss in Net income. Corporate securities 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. Chubb developed projected cash flows for corporate securities using market observable data, issuer-specific information, and credit ratings. We use historical default data by Moody’s Investors Service (Moody’s) rating category to calculate a 1-in-100 year probability of default, which results in a default assumption in excess of the historical mean default rate. Consistent with management's approach, Chubb assumed a 32 percent recovery rate (the par value of a defaulted security that will be recovered) across all rating categories, rather than using Moody's historical mean recovery rate of 42 percent . We believe that use of a default assumption, in excess of the historical mean, is conservative in light of current market conditions. The following table presents default assumptions by Moody's rating category (historical mean default rate provided for comparison): Moody's Rating Category 1-in-100 Year Default Rate Historical Mean Default Rate Investment Grade: Aaa-Baa 0.0-1.3% 0.0-0.3% Below Investment Grade: Ba 4.8 % 1.0 % B 12.1 % 3.2 % Caa-C 36.8 % 10.5 % Application of the methodology and assumptions described above resulted in credit losses recognized in Net income for corporate securities of $ 5 million, $ 30 million, and $ 50 million for the years ended December 31, 2017 , 2016 , and 2015 , respectively. Mortgage-backed securities 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. We develop specific assumptions using market data, where available, and include internal estimates as well as estimates published by rating agencies and other third-party sources. We project default rates by mortgage sector considering current underlying mortgage loan performance, generally assuming lower loss severity for Prime sector bonds versus ALT-A and Sub-prime bonds. These estimates are extrapolated along a default timing curve to estimate the total lifetime pool default rate. Other assumptions used contemplate the actual collateral attributes, including geographic concentrations, rating agency loss projections, rating actions, and current market prices. If cash flow projections indicate that losses will exceed the credit enhancement for a given tranche, then we do not expect to recover our amortized cost basis, and we recognize an estimated credit loss in Net income. For the years ended December 31, 2017 and 2015 , there were no credit losses recognized in Net income for mortgage-backed securities. For the year ended December 31, 2016 , there was $ 1 million of credit losses recognized in Net income for mortgage-backed securities.

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. Chubb is also required to restrict assets pledged under repurchase agreements. We also use trust funds in certain large reinsurance transactions where the trust funds are set up for the benefit of the ceding companies and generally take the place of letter of credit (LOC) requirements. We also have investments in segregated portfolios primarily to provide collateral or guarantees for LOC and derivative transactions. Included in restricted assets at December 31, 2017 and 2016 , are investments, primarily fixed maturities, totaling $23.3 billion and $ 20.1 billion , and cash of $123 million and $103 million, respectively.

Fair Value Disclosures [Abstract] | |
Fair value measurements | Fair value measurements a ) Fair value hierarchy Fair value of financial assets and financial liabilities is estimated based on the framework established in the fair value accounting guidance. The guidance defines fair value as the price to sell an asset or transfer a liability (an exit price) in an orderly transaction between market participants and establishes a three-level valuation hierarchy based on the reliability of the inputs. The fair value hierarchy gives the highest priority to quoted prices in active markets and the lowest priority to unobservable data. The three levels of the hierarchy are as follows: • Level 1 – Unadjusted quoted prices for identical assets or liabilities in active markets; • Level 2 – Includes, among other items, inputs other than quoted prices that are observable for the asset or liability such as interest rates and yield curves, quoted prices for similar assets and liabilities in active markets, and quoted prices for identical or similar assets and liabilities in markets that are not active; and • Level 3 – Inputs that are unobservable and reflect management’s judgments about assumptions that market participants would use in pricing an asset or liability. We categorize financial instruments within the valuation hierarchy at the balance sheet date based upon the lowest level of inputs that are significant to the fair value measurement. Accordingly, transfers between levels within the valuation hierarchy occur when there are significant changes to the inputs, such as increases or decreases in market activity, changes to the availability of current prices, changes to the transparency to underlying inputs, and whether there are significant variances in quoted prices. Transfers in and/or out of any level are assumed to occur at the end of the period. We use pricing services to obtain fair value measurements for the majority of our investment securities. Based on management’s understanding of the methodologies used, these pricing services only produce an estimate of fair value if there is observable market information that would allow them to make a fair value estimate. Based on our understanding of the market inputs used by the pricing services, all applicable investments have been valued in accordance with GAAP. We do not adjust prices obtained from pricing services. The following is a description of the valuation techniques and inputs used to determine fair values for financial instruments carried at fair value, as well as the general classification of such financial instruments pursuant to the valuation hierarchy. Fixed maturities We use pricing services to estimate fair value measurements for the majority of our fixed maturities. The pricing services use market quotations for fixed maturities that have quoted prices in active markets; such securities are classified within Level 1. For fixed maturities other than U.S. Treasury securities that generally do not trade on a daily basis, the pricing services prepare estimates of fair value measurements using their pricing applications, which include available relevant market information, benchmark curves, benchmarking of like securities, sector groupings, and matrix pricing. Additional valuation factors that can be taken into account are nominal spreads, dollar basis, and liquidity adjustments. The pricing services evaluate each asset class based on relevant market and credit information, perceived market movements, and sector news. The market inputs used in the pricing evaluation, listed in the approximate order of priority include: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, reference data, and industry and economic events. The extent of the use of each input is dependent on the asset class and the market conditions. Given the asset class, the priority of the use of inputs may change, or some market inputs may not be relevant. Additionally, fixed maturities valuation is more subjective when markets are less liquid due to the lack of market based inputs (i.e., stale pricing), which may increase the potential that an investment's estimated fair value is not reflective of the price at which an actual transaction would occur. The overwhelming majority of fixed maturities are classified within Level 2 because the most significant inputs used in the pricing techniques are observable. For a small number of fixed maturities, we obtain a single broker quote (typically from 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. 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) and are excluded from the fair value hierarchy table below. 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 include equity securities classified within Level 1, and fixed maturities, classified within Level 2, held in rabbi trusts maintained by Chubb for deferred compensation plans and are classified within the valuation hierarchy on the same basis as other equity securities and fixed maturities. Other investments for which pricing is unobservable are classified within Level 3. 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 Chubb’s obligation to return the collateral plus interest as it is reported at contract value and not fair value in the Consolidated balance sheets. Investment derivative instruments Actively traded investment derivative instruments, including futures, options, and forward contracts are classified within Level 1 as fair values are based on quoted market prices. The fair value of cross-currency swaps is based on market valuations and is classified within Level 2. Investment derivative instruments are recorded in either Other assets or Accounts payable, accrued expenses, and other liabilities in the Consolidated balance sheets. Other derivative instruments We generally 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, an increase in 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. At December 31, 2017, we held no positions in option contracts on equity market indices. The fair value of the majority of the remaining positions in other derivative instruments is based on significant observable inputs including equity security and interest rate indices. Accordingly, these are classified within Level 2. Other derivative instruments based on unobservable inputs are classified within Level 3. Other derivative instruments are recorded in either Other assets or Accounts payable, accrued expenses, and other liabilities in the Consolidated balance sheets. Separate account assets Separate account assets represent segregated funds where investment risks are borne by the customers, except to the extent of certain guarantees made by Chubb. Separate account assets comprise mutual funds classified within Level 1 in the valuation hierarchy on the same basis as other equity securities traded in active markets. 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, Chubb 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 factors, including interest rates, equity markets, credit risk, current account value, market volatility, expected annuitization rates and other 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. 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 3 percent to 9 percent per annum) during the surrender charge period of the GMIB contract, followed by a “spike” lapse rate (ranging from about 6 percent to 33 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 . Partial withdrawals and the impact of older policyholders with tax-qualified contracts (due to required minimum distributions) are also reflected in our modeling. 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. All GMIB reinsurance treaties include claim limits to protect Chubb in the event that actual annuitization behavior is significantly higher than expected. In general, Chubb 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 fully credible annuitization experience for all clients. The level of annuitization assumptions at December 31, 2017 are as follows: % of total GMIB guaranteed value Year of GMIB eligibility Maximum annuitization rate(s) (per year) Maximum annuitization rates based on 67% First year 2% - 52% Actual Experience Subsequent years 1% - 100% 3% First year N/A N/A (1) Subsequent years 12%, 100% Weighted average (2) 30% First year 25%, 56% Weighted average (2) Subsequent years 12%, 36% (1) Because all policies in this bracket are past the first year of eligibility, first year annuitization assumptions are no longer modeled. (2) Weighted average of two different annuitization rates. 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 regularly re-evaluated by management and enhanced, as appropriate, based upon additional experience obtained related to policyholder behavior and availability of updated information such as market conditions, market participant assumptions, and demographics of in-force annuities. Because of the significant use of unobservable inputs including policyholder behavior, GLB reinsurance is classified within Level 3. In the fourth quarter of 2017, we completed a review of policyholder behavior related to annuitizations, partial withdrawals, lapses, and mortality for our variable annuity reinsurance business. • As annuitization experience continued to emerge, we refined our annuitization assumptions including age-based behavior, which generally lowered the annuitization rate. The change in annuitization assumptions decreased the fair value of GLB liabilities and generated a realized gain of approximately $117 million . • Reinsured policies allow for policyholders to make periodic withdrawals from their account values without lapsing the policy. The partial withdrawal results in a reduction to the associated guaranteed value that is either equal or proportional to the amount of the reduction in account value. Based on continued emerging experience, we refined our assumptions around the types of partial withdrawals according to their impact on guaranteed value. This resulted in an increase to the fair value of GLB liabilities generating a realized loss of approximately $43 million . • As lapse experience continued to emerge, we further refined our assumptions which resulted in a net increase to the fair value of GLB liabilities generating a realized loss of approximately $9 million . • We studied mortality experience for our variable annuity business for the first time this year and subsequently refined our mortality assumptions. The updated mortality rates increased the fair value of GLB liabilities generating a realized loss of approximately $25 million . In addition to the updates described above, we updated aspects of our valuation model relating to interest rates during the year ended December 31, 2017. This resulted in a decrease to the fair value of GLB liabilities generating a realized gain of approximately $94 million . During the year ended December 31, 2017 , we also made minor technical refinements to the internal valuation model which resulted in no material impact on the financial statements.

There were no transfers of financial instruments between Level 1 and Level 2 for the years ended December 31, 2017, 2016, and 2015. Fair value of alternative investments Alternative investments include investment funds, limited partnerships, and partially-owned investment companies measured at fair value using NAV as a practical expedient. The following table presents, by investment category, the expected liquidation period, fair value, and maximum future funding commitments of alternative investments: December 31 December 31 2017 2016 (in millions of U.S. dollars) Expected Liquidation Period of Underlying Assets Fair Value Maximum Future Funding Commitments Fair Value Maximum Future Funding Commitments Financial 5 to 9 Years $ 540 $ 330 $ 548 $ 428 Real Assets 3 to 7 Years 651 114 536 230 Distressed 3 to 7 Years 289 141 485 179 Private Credit 3 to 7 Years 187 327 236 259 Traditional 3 to 15 Years 1,656 3,149 1,550 930 Vintage 1 to 2 Years 30 — 21 14 Investment funds Not Applicable 270 — 251 — $ 3,623 $ 4,061 $ 3,627 $ 2,040 Included in all categories in the above table, except for Investment funds, are investments for which Chubb will never have the contractual option to redeem but receives distributions based on the liquidation of the underlying assets. Further, for all categories except for Investment funds, Chubb does not have the ability to sell or transfer the investments without the consent from the general partner of individual funds. Investment Category Consists of investments in private equity funds: Financial targeting financial services companies such as financial institutions and insurance services worldwide Real Assets targeting investments related to hard physical assets such as real estate, infrastructure, and natural resources Distressed targeting distressed corporate debt/credit and equity opportunities in the U.S. Private Credit targeting privately originated corporate debt investments including senior secured loans and subordinated bonds Traditional employing traditional private equity investment strategies such as buyout and growth equity globally Vintage made before 2002 or where the funds’ commitment periods had already expired Investment funds Chubb’s investment funds employ various investment strategies such as long/short equity and arbitrage/distressed. Included in this category are investments for which Chubb 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 Chubb 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 Chubb 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, Chubb 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 Chubb’s investment within several months of the notification. Notice periods for redemption of the investment funds range between 5 and 120 days. Chubb can redeem its investment funds without consent from the investment fund managers. Level 3 financial instruments The fair values of assets and liabilities measured at fair value using significant unobservable inputs (Level 3) consist of various inputs and assumptions that management makes when determining fair value. Management analyzes changes in fair value measurements classified within Level 3 by comparing pricing and returns of our investments to benchmarks, including month-over-month movements, investment credit spreads, interest rate movements, and credit quality of securities. The following table presents the significant unobservable inputs used in the Level 3 liability valuations. Excluded from the table below are inputs used to determine the fair value of Level 3 assets which are based on single broker quotes and contain no quantitative unobservable inputs developed by management.

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 Chubb’s share of the net assets based on the financial statements provided by those companies and are excluded from the valuation hierarchy tables below. Short- and long-term debt, repurchase agreements, and trust preferred securities Where practical, fair values for short-term debt, long-term debt, repurchase agreements, and trust preferred securities are estimated using discounted cash flow calculations based principally on observable inputs including incremental borrowing rates, which reflect Chubb’s credit rating, for similar types of borrowings with maturities consistent with those remaining for the debt being valued.

Reinsurance Disclosures [Abstract] | |
Reinsurance | Reinsurance a) Consolidated reinsurance Chubb purchases reinsurance to manage various exposures including catastrophe risks. Although reinsurance agreements contractually obligate Chubb's reinsurers to reimburse it for the agreed-upon portion of its gross paid losses, they do not discharge Chubb's primary liability. The amounts for net premiums written and net premiums earned in the Consolidated statements of operations are net of reinsurance. The following table presents direct, assumed, and ceded premiums: Year Ended December 31 (in millions of U.S. dollars) 2017 2016 2015 Premiums written Direct $ 33,137 $ 31,543 $ 19,879 Assumed 3,239 3,440 3,932 Ceded (7,132 ) (6,838 ) (6,098 ) Net $ 29,244 $ 28,145 $ 17,713 Premiums earned Direct $ 32,782 $ 31,811 $ 19,355 Assumed 3,332 3,744 3,676 Ceded (7,080 ) (6,806 ) (5,818 ) Net $ 29,034 $ 28,749 $ 17,213 Ceded losses and loss expenses incurred were $5.5 billion , $4.1 billion , and $3.1 billion for the years ended December 31, 2017 , 2016 , and 2015 , respectively. b) Reinsurance recoverable on ceded reinsurance December 31 December 31 (in millions of U.S. dollars) 2017 2016 Reinsurance recoverable on unpaid losses and loss expenses (1) $ 14,014 $ 12,708 Reinsurance recoverable on paid losses and loss expenses (1) 1,020 869 Reinsurance recoverable on losses and loss expenses (1) $ 15,034 $ 13,577 Reinsurance recoverable on policy benefits (1) $ 184 $ 182 (1) Net of a provision for uncollectible reinsurance. The increase in reinsurance recoverable on loss and loss expenses was principally related to the California wildfires and other catastrophe losses in 2017. 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 Chubb, primarily because of disputes under reinsurance contracts and insolvencies. We have established provisions for amounts estimated to be uncollectible. At December 31, 2017 and 2016 , the provision for uncollectible reinsurance was $321 million and $ 300 million, respectively. The following tables present a listing, at December 31, 2017 , of the categories of Chubb's reinsurers: December 31, 2017 Gross Reinsurance Recoverable on Loss and Loss Expenses Provision for Uncollectible Reinsurance % of Gross Reinsurance Recoverable (in millions of U.S. dollars, except for percentages) Categories Largest reinsurers $ 5,190 $ 59 1.1 % Other reinsurers rated A- or better 5,898 58 1.0 % Other reinsurers with ratings lower than A- or not rated 681 75 11.0 % Pools 577 15 2.6 % Structured settlements 550 16 2.9 % Captives 2,199 18 0.8 % Other 260 80 30.8 % Total $ 15,355 $ 321 2.1 % Largest Reinsurers Berkshire Hathaway Insurance Group Lloyd's of London Swiss Re Group HDI Group (Hannover Re) Munich Re Group Categories of Chubb's reinsurers Comprises: Largest reinsurers • All groups of reinsurers or captives where the gross recoverable exceeds one percent of Chubb's total shareholders' equity. Other reinsurers rated A- or better • All reinsurers rated A- or better that were not included in the largest reinsurer category. Other reinsurers rated lower than A- or not rated • All reinsurers rated lower than A- or not rated that were not included in the largest reinsurer category. Pools • Related to Chubb's voluntary pool participation and Chubb's mandatory pool participation required by law in certain states. Structured settlements • Annuities purchased from life insurance companies to settle claims. Since we retain ultimate liability in the event that the life company fails to pay, we reflect the amounts as both a liability and a recoverable/receivable for GAAP purposes. Captives • Companies established and owned by our insurance clients to assume a significant portion of their direct insurance risk from Chubb; structured to allow clients to self-insure a portion of their reinsurance risk. It generally is our policy to obtain collateral equal to expected losses. Where appropriate, exceptions are granted but only with review and approval at a senior officer level. Excludes captives included in the largest reinsurer category. Other • Amounts recoverable that are in dispute or are from companies that are in supervision, rehabilitation, or liquidation. The provision for uncollectible reinsurance is principally based on an analysis of the credit quality of the reinsurer and collateral balances. We establish the provision for uncollectible reinsurance for the Other category based on a case-by-case analysis of individual situations including the merits of the underlying matter, credit and collateral analysis, and consideration of our collection experience in similar situations. c ) Assumed life reinsurance programs involving minimum benefit guarantees under variable annuity contracts The following table presents income and expenses relating to GMDB and GLB reinsurance. GLBs include GMIBs as well as some GMABs originating in Japan. Year Ended December 31 (in millions of U.S. dollars) 2017 2016 2015 GMDB Net premiums earned $ 49 $ 55 $ 61 Policy benefits and other reserve adjustments $ 40 $ 45 $ 34 GLB Net premiums earned $ 110 $ 118 $ 121 Policy benefits and other reserve adjustments 105 52 45 Net realized gains (losses) 363 48 (203 ) Gain (loss) recognized in Net income $ 368 $ 114 $ (127 ) Net cash received and other 65 79 98 Net decrease (increase) in liability $ 303 $ 35 $ (225 ) Net realized gains (losses) in the table above include gains (losses) related to foreign exchange and fair value adjustments on insurance derivatives and exclude gains (losses) on S&P put options and futures used to partially offset the risk in the GLB reinsurance portfolio. Refer to Note 10 for additional information. At December 31, 2017 and 2016 , the reported liability for GMDB reinsurance was $129 million and $120 million, respectively. At December 31, 2017 and 2016 , the reported liability for GLB reinsurance was $550 million and $853 million, respectively, which includes a fair value derivative adjustment of $204 million and $559 million, respectively. Reported liabilities for both GMDB and GLB reinsurance are determined using internal valuation models. Such valuations require considerable judgment and are subject to significant uncertainty. The valuation of these products is subject to fluctuations arising from, among other factors, changes in interest rates, changes in equity markets, changes in credit markets, changes in the allocation of the investments underlying annuitants’ account values, and assumptions regarding future policyholder behavior. These models and the related assumptions are regularly reviewed by management and enhanced, as appropriate, based upon improvements in modeling assumptions and availability of updated information, such as market conditions and demographics of in-force annuities. Variable Annuity Net Amount at Risk The net amount at risk is defined as the present value of future claim payments assuming policy account values and guaranteed values are fixed at the valuation date ( December 31, 2017 and 2016 , respectively) and reinsurance coverage ends at the earlier of the maturity of the underlying variable annuity policy or the reinsurance treaty. In addition, the following assumptions were used: (in millions of U.S. dollars, except for percentages) Net amount at risk Reinsurance covering December 31, 2017 December 31, 2016 2017 Future claims discount rate Other assumptions Total claims at 100% mortality at December 31, 2017 (1) GMDB Risk Only $ 279 $ 341 4.00% - 4.50% No lapses or withdrawals $ 189 Mortality according to 100% of the Annuity 2000 mortality table GLB Risk Only $ 691 $ 800 4.25% - 4.75% No deaths, lapses or withdrawals N/A Annuitization at a frequency most disadvantageous to Chubb (2) Claim calculated using interest rates in line with rates used to calculate reserve Both Risks: (3) GMDB $ 81 $ 88 4.25% - 4.75% No lapses or withdrawals $ 18 Mortality according to 100% of the Annuity 2000 mortality table GLB $ 392 $ 464 4.25% - 4.75% Annuitization at a frequency most disadvantageous to Chubb (2) N/A Claim calculated using interest rates in line with rates used to calculate reserve (1) Takes into account all applicable reinsurance treaty claim limits. (2) Annuitization at a level that maximizes claims taking into account the treaty limits. (3) Covering both the GMDB and GLB risks on the same underlying policyholders. The average attained age of all policyholders for all risk categories above, weighted by the guaranteed value of each reinsured policy, is approximately 70 years. |

Goodwill and Other intangible assets At December 31, 2017 and 2016 , Goodwill was $ 15.5 billion and $ 15.3 billion, respectively, and Other intangible assets were $ 6.5 billion and $ 6.8 billion, respectively. a) Goodwill The following table presents a roll-forward of Goodwill by segment: (in millions of U.S. dollars) North America Commercial P&C Insurance North America Personal P&C Insurance North America Agricultural Insurance Overseas General Insurance Global Reinsurance Life Insurance Chubb Consolidated Balance at December 31, 2015 $ 1,203 $ 196 $ 134 $ 2,078 $ 365 $ 820 $ 4,796 Acquisition of Chubb Corp 5,714 2,025 — 2,775 — — 10,514 Foreign exchange revaluation and other 44 14 — (36 ) — — 22 Balance at December 31, 2016 $ 6,961 $ 2,235 $ 134 $ 4,817 $ 365 $ 820 $ 15,332 Foreign exchange revaluation and other 15 5 — 187 — 2 209 Balance at December 31, 2017 $ 6,976 $ 2,240 $ 134 $ 5,004 $ 365 $ 822 $ 15,541 b) Other intangible assets The majority of the Other intangible assets balance at December 31, 2017 relates to the Chubb Corp acquisition and comprised of $ 3.5 billion that are subject to amortization, principally Agency distribution relationships and renewal rights, and $ 3.0 billion that are not subject to amortization, principally trademarks. This compares to $ 3.8 billion and $ 3.0 billion at December 31, 2016, respectively. Amortization of purchased intangibles Amortization expense related to purchased intangibles amounted to $260 million , $ 19 million, and $ 171 million for the years ended December 31, 2017 , 2016 , and 2015 , respectively. The increase in amortization expense of purchased intangibles primarily reflects higher intangible amortization expense related to agency distribution relationships and renewal rights and lower amortization benefit from the fair value adjustment on Unpaid losses and loss expenses, both related to the Chubb Corp acquisition. The following table presents, as of December 31, 2017 , the expected estimated pre-tax amortization expense (benefit) of purchased intangibles, at current foreign currency exchange rates, for the next five years: Associated with the Chubb Corp Acquisition For the Year Ending December 31 (in millions of U.S. dollars) Agency distribution relationships and renewal rights Internally developed technology Fair value adjustment on Unpaid losses and loss expense (1) Total Other intangible assets Total Amortization of purchased intangibles 2018 $ 325 $ 32 $ (102 ) $ 255 $ 83 $ 338 2019 282 — (63 ) 219 75 294 2020 241 — (36 ) 205 67 272 2021 218 — (20 ) 198 61 259 2022 198 — (14 ) 184 57 241 Total $ 1,264 $ 32 $ (235 ) $ 1,061 $ 343 $ 1,404 (1) In connection with the Chubb Corp acquisition, we recorded an increase to Unpaid losses and loss expenses acquired to adjust the carrying value of Chubb Corp's historical unpaid losses and loss expenses to fair value as of the acquisition date. This fair value adjustment amortizes through Amortization of purchased intangibles on the Consolidated statements of operations over a range of 5 to 17 years. The balance of the fair value adjustment on Unpaid losses and loss expense at December 31, 2017 was $309 million . Refer to Note 1(h) for additional information. c) VOBA The following table presents a roll-forward of VOBA: (in millions of U.S. dollars) 2017 2016 2015 Balance, beginning of year $ 355 $ 395 $ 466 Amortization of VOBA (1) (35 ) (41 ) (42 ) Foreign exchange revaluation 6 1 (29 ) Balance, end of year $ 326 $ 355 $ 395 (1) Recognized in Policy acquisition costs in the Consolidated statements of operations.

Liability for Claims and Claims Adjustment Expense [Abstract] | |
Unpaid Losses and Loss Expenses | Unpaid losses and loss expenses Chubb establishes reserves for the estimated unpaid ultimate liability for losses and loss expenses under the terms of its policies and agreements. Reserves include estimates for both claims that have been reported and for IBNR claims, and include estimates of expenses associated with processing and settling these claims. Reserves are recorded in Unpaid losses and loss expenses in the consolidated balance sheets. While we believe that our reserves for unpaid losses and loss expenses at December 31, 2017 are adequate, new information or trends may lead to future developments in incurred loss and loss expenses significantly greater or less than the reserves provided. Any such revisions could result in future changes in estimates of losses or reinsurance recoverable and would be reflected in our results of operations in the period in which the estimates are changed. The following table presents a reconciliation of Unpaid losses and loss expenses: Year Ended December 31 (in millions of U.S. dollars) 2017 2016 2015 Gross unpaid losses and loss expenses, beginning of year $ 60,540 $ 37,303 $ 38,315 Reinsurance recoverable on unpaid losses (1) (12,708 ) (10,741 ) (11,307 ) Net unpaid losses and loss expenses, beginning of year 47,832 26,562 27,008 Acquisition of subsidiaries — 21,402 417 Total 47,832 47,964 27,425 Net losses and loss expenses incurred in respect of losses occurring in: Current year 19,391 17,256 10,030 Prior years (2) (937 ) (1,204 ) (546 ) Total 18,454 16,052 9,484 Net losses and loss expenses paid in respect of losses occurring in: Current year 6,575 5,899 4,053 Prior years 10,873 9,816 5,612 Total 17,448 15,715 9,665 Foreign currency revaluation and other 327 (469 ) (682 ) Net unpaid losses and loss expenses, end of year 49,165 47,832 26,562 Reinsurance recoverable on unpaid losses (1) 14,014 12,708 10,741 Gross unpaid losses and loss expenses, end of year $ 63,179 $ 60,540 $ 37,303 (1) Net of provision for uncollectible reinsurance. (2) Relates to prior period loss reserve development only and excludes prior period development related to reinstatement premiums, expense adjustments, and earned premiums totaling $108 million , $69 million , and nil, for 2017, 2016, and 2015, respectively. The increase in gross and net unpaid losses and loss expenses in 2017 primarily reflects the significant catastrophe events, principally from California wildfires, hurricanes Harvey, Irma, and Maria and the earthquakes in Mexico. The increase in gross and net unpaid losses and loss expenses in 2016 reflects the acquisition of Chubb Corp. The loss development tables under section c) below, present Chubb’s historical incurred and paid claims development by broad product line through December 31, 2017 , net of reinsurance, as well as the cumulative number of reported claims, IBNR balances, and other supplementary information. The following table presents a reconciliation of the loss development tables to the liability for unpaid losses and loss expenses in the consolidated balance sheet: Reconciliation of Reserve Balances to Liability for Unpaid Loss and Loss Expenses (in millions of U.S. dollars) December 31, 2017 Presented in the loss development tables: North America Commercial P&C Insurance — Workers' Compensation $ 8,873 North America Commercial P&C Insurance — Liability 16,631 North America Commercial P&C Insurance — Other Casualty 1,789 North America Commercial P&C Insurance — Non-Casualty 2,398 North America Personal P&C Insurance 2,421 Overseas General Insurance — Casualty 6,026 Overseas General Insurance — Non-Casualty 2,549 Global Reinsurance — Casualty 1,340 Global Reinsurance — Non-Casualty 371 Excluded from the loss development tables: Other 4,302 Net unpaid loss and allocated loss adjustment expense 46,700 Ceded unpaid loss and allocated loss adjustment expense: North America Commercial P&C Insurance — Workers' Compensation $ 1,737 North America Commercial P&C Insurance — Liability 4,133 North America Commercial P&C Insurance — Other Casualty 813 North America Commercial P&C Insurance — Non-Casualty 1,336 North America Personal P&C Insurance 503 Overseas General Insurance — Casualty 2,550 Overseas General Insurance — Non-Casualty 1,269 Global Reinsurance — Casualty 76 Global Reinsurance — Non-Casualty 142 Other 1,628 Ceded unpaid loss and allocated loss adjustment expense 14,187 Unpaid loss and loss expense on other than short-duration contracts (1) 810 Unpaid unallocated loss adjustment expenses 1,482 Unpaid losses and loss expenses $ 63,179 (1) Primarily includes the claims reserve of our international A&H business and Life Insurance segment reserves. Business excluded from the loss development tables “Other” shown in the reconciliation table above comprises businesses excluded from the loss development tables below: • North America Agricultural Insurance segment business, which is short-tailed with the majority of the liabilities expected to be resolved in the ensuing twelve months; • Corporate segment business, which includes run-off liabilities such as asbestos and environmental and other mass tort exposures and which impact accident years older than those shown in the exhibits below; • Life Insurance segment business, which is generally written using long-duration contracts; and • Certain subsets of our business due to data limitations or unsuitability to the development table presentation, including: ◦ We underwrite loss portfolio transfers at various times; by convention, all premium and losses associated with these transactions are recorded to the policy period of the transaction, even though the accident dates of the claims covered may be a decade or more in the past. We also underwrite certain high attachment, high limit, multiple-line and excess of aggregate coverages for large commercial clients. Changes in incurred loss and cash flow patterns are volatile and sufficiently different from those of typical insureds. This category includes the loss portfolio transfer of Fireman’s Fund personal lines run-off liabilities and Alternative Risk Solutions business within the North America Commercial P&C segment; ◦ 2015 and prior paid history on a subset of previously acquired international businesses, within the Overseas General Insurance segment, due to limitations on the data prior to the acquisition; ◦ Reinsurance recoverable bad debt; ◦ Purchase accounting adjustments related to unpaid losses and loss expenses for Chubb Corp. a) Description of Reserving Methodologies Our recorded reserves represent management's best estimate of the provision for unpaid claims as of the balance sheet date. Management's best estimate is developed after collaboration with actuarial, underwriting, claims, legal, and finance departments and culminates with the input of reserve committees. Each business unit reserve committee includes the participation of the relevant parties from actuarial, finance, claims, and unit senior management and has the responsibility for finalizing, recommending and approving the estimate to be used as management's best estimate. Reserves are further reviewed by Chubb's Chief Actuary and senior management. The objective of such a process is to determine a single estimate that we believe represents a better estimate than any other and which is viewed by management to be the best estimate of ultimate loss settlements. This estimate is based on a combination of exposure and experience-based actuarial methods (described below) and other considerations such as claims reviews, reinsurance recovery assumptions and/or input from other knowledgeable parties such as underwriting. Exposure-based methods are most commonly used on relatively immature origin years (i.e., the year in which the losses were incurred — “accident year” or “report year”), while experience-based methods provide a view based on the projection of loss experience that has emerged as of the valuation date. Greater reliance is placed upon experience-based methods as the pool of emerging loss experience grows and where it is deemed sufficiently credible and reliable as the basis for the estimate. In comparing the held reserve for any given origin year to the actuarial projections, judgment is required as to the credibility, uncertainty and inherent limitations of applying actuarial techniques to historical data to project future loss experience. Examples of factors that impact such judgments include, but are not limited to, the following: • nature and complexity of underlying coverage provided and net limits of exposure provided; • segmentation of data to provide sufficient homogeneity and credibility for loss projection methods; • extent of credible internal historical loss data and reliance upon industry information as required; • historical variability of actual loss emergence compared with expected loss emergence; • extent of emerged loss experience relative to the remaining expected period of loss emergence; • rate monitor information for new and renewal business; • facts and circumstances of large claims; • impact of applicable reinsurance recoveries; and • nature and extent of underlying assumptions. We have actuarial staff within each of our business units who analyze loss reserves (including loss expenses) and regularly project estimates of ultimate losses and the corresponding indications of the required IBNR reserve. Our reserving approach is a comprehensive ground-up process using data at a detailed level that reflects the specific types and coverages of the diverse products written by our various operations. The data presented in this disclosure was prepared on a more aggregated basis and with a focus on changes in incurred loss estimates over time as well as associated cash flows. We note that data prepared on this basis may not demonstrate the full spectrum of characteristics that are evident in the more detailed level studied internally. We perform an actuarial reserve review for each product line at least once a year. For most product lines, one or more standard actuarial reserving methods may be used to determine estimates of ultimate losses and loss expenses, and from these estimates, a single actuarial central estimate is selected. The actuarial central estimate is an input to the reserve committee process described above. For the few product lines that do not lend themselves to standard actuarial reserving methods, appropriate techniques are applied to produce the actuarial central estimates. For example, run-off asbestos and environmental liability estimates are better suited to the application of account-specific exposure-based analyses to best evaluate their associated aggregate reserve levels. b) Standard actuarial reserving methods Standard actuarial reserving methods include, but are not limited to, expected loss ratio, paid and reported loss development, and Bornhuetter-Ferguson methods. A general description of these methods is provided below. In addition to these standard methods, depending upon the product line characteristics and available data, we may use other recognized actuarial methods and approaches. Implicit in the standard actuarial methods that we generally utilize is the need for two fundamental assumptions: first, the pattern by which losses are expected to emerge over time for each origin year, and second the expected loss ratio for each origin year. The expected loss ratio for any particular origin year is selected after consideration of a number of factors, including historical loss ratios adjusted for rate changes, premium and loss trends, industry benchmarks, the results of policy level loss modeling at the time of underwriting, and/or other more subjective considerations for the product line (e.g., terms and conditions) and external environment as noted above. The expected loss ratio for a given origin year is initially established at the start of the origin year as part of the planning process. This analysis is performed in conjunction with underwriters and management. The expected loss ratio method arrives at an ultimate loss estimate by multiplying the expected ultimate loss ratio by the corresponding premium base. This method is most commonly used as the basis for the actuarial central estimate for immature origin periods on product lines where the actual paid or reported loss experience is not yet deemed sufficiently credible to serve as the principal basis for the selection of ultimate losses. The expected loss ratio for a given origin year may be modified over time if the underlying assumptions differ from the original assumptions (e.g., the assessment of prior year loss ratios, loss trend, rate changes, actual claims, or other information). Our selected paid and reported development patterns provide a benchmark against which the actual emerging loss experience can be monitored. Where possible, development patterns are selected based on historical loss emergence by origin year. For product lines where the historical data is viewed to have low statistical credibility, the selected development patterns also reflect relevant industry benchmarks and/or experience from similar product lines written elsewhere within Chubb. This most commonly occurs for relatively new product lines that have limited historical data or for high severity/low frequency portfolios where our historical experience exhibits considerable volatility and/or lacks credibility. The paid and reported loss development methods convert the selected loss emergence pattern to a set of multiplicative factors which are then applied to actual paid or reported losses to arrive at an estimate of ultimate losses for each period. Due to their multiplicative nature, the paid and reported loss development methods will leverage differences between actual and expected loss emergence. These methods tend to be utilized for more mature origin periods and for those portfolios where the loss emergence has been relatively consistent over time. The Bornhuetter-Ferguson method is a combination of the expected loss ratio method and the loss development method, where the loss development method is given more weight as the origin year matures. This approach allows a logical transition between the expected loss ratio method which is generally utilized at earlier maturities and the loss development methods which are typically utilized at later maturities. We usually apply this method using reported loss data although paid data may also be used. Short-tail business Short-tail business generally describes product lines for which losses are typically known and paid shortly after the loss actually occurs. This would include, for example, most property, personal accident, and automobile physical damage policies that we write. Due to the short reporting and development pattern for these product lines, the uncertainty associated with our estimate of ultimate losses for any particular accident period diminishes relatively quickly as actual loss experience emerges. We typically assign credibility to methods that incorporate actual loss emergence, such as the paid and reported loss development and Bornhuetter-Ferguson methods, sooner than would be the case for long-tail lines at a similar stage of development for a given origin year. The reserving process for short-tail losses arising from catastrophic events typically involves an assessment by the claims department, in conjunction with underwriters and actuaries, of our exposure and estimated losses immediately following an event and then subsequent revisions of the estimated losses as our insureds provide updated actual loss information. Long-tail business Long-tail business describes lines of business for which specific losses may not be known/reported for some period and for which claims can take significant time to settle/close. This includes most casualty lines such as general liability, D&O, and workers' compensation. There are various factors contributing to the uncertainty and volatility of long-tail business. Among these are: • The nature and complexity of underlying coverage provided and net limits of exposure provided; • Our historical loss data and experience is sometimes too immature and lacking in credibility to rely upon for reserving purposes. Where this is the case, in our reserve analysis we may utilize industry loss ratios or industry benchmark development patterns that we believe reflect the nature and coverage of the underwritten business and its future development, where available. For such product lines, actual loss experience may differ from industry loss statistics as well as loss experience for previous underwriting years; • The difficulty in estimating loss trends, claims inflation (e.g., medical and judicial) and underlying economic conditions; • The need for professional judgment to estimate loss development patterns beyond that represented by historical data using supplemental internal or industry data, extrapolation, or a blend of both; • The need to address shifts in mix over time when applying historical paid and reported loss development patterns from older origin years to more recent origin years. For example, changes over time in the processes and procedures for establishing case reserves can distort reported loss development patterns or changes in ceded reinsurance structures by origin year can alter the development of paid and reported losses; • Loss reserve analyses typically require loss or other data be grouped by common characteristics in some manner. If data from two combined lines of business exhibit different characteristics, such as loss payment patterns, the credibility of the reserve estimate could be affected. Additionally, since casualty lines of business can have significant intricacies in the terms and conditions afforded to the insured, there is an inherent risk as to the homogeneity of the underlying data used in performing reserve analyses; and • The applicability of the price change data used to estimate ultimate loss ratios for most recent origin years. As described above, various factors are considered when determining appropriate data, assumptions, and methods used to establish the loss reserve estimates for long-tail product lines. These factors may also vary by origin year for given product lines. The derivation of loss development patterns from data and the selection of a tail factor to project ultimate losses from actual loss emergence require considerable judgment, particularly with respect to the extent to which historical loss experience is relied upon to support changes in key reserving assumptions. c) Loss Development Tables The tables were designed to present business with similar risk characteristics which exhibit like development patterns and generally similar trends, in order to provide insight into the nature, amount, timing and uncertainty of cash flows related to our claims liabilities. Each table follows a similar format and reflects the following: • The incurred loss triangle includes both reported case reserves and IBNR liabilities. • Both the incurred and paid loss triangles include allocated loss adjustment expense (i.e., defense and investigative costs particular to individual claims) but exclude unallocated loss adjustment expense (i.e., the costs associated with internal claims staff and third-party administrators). • The amounts in both triangles for the years ended December 31, 2008 , to December 31, 2016 and average historical claim duration as of December 31, 2017 , are presented as supplementary information. • All data presented in the triangles is net of reinsurance recoverables. • The IBNR reserves shown to the right of each incurred loss development exhibit reflect the net IBNR recorded as of December 31, 2017 . • The tables are presented retrospectively with respect to acquisitions where these are material and doing so is practicable. Most notably, the Chubb Corp acquisition is presented retrospectively. The unaudited consolidated data is presented solely for informational purposes and is not necessarily indicative of the consolidated data that might have been observed had the transactions been completed prior to the date indicated. Historical dollar amounts are presented in this footnote on a constant-currency basis, which is achieved by assuming constant foreign exchange rates for all periods in the loss triangles, translating prior period amounts using the same local currency exchange rates as the current year end. The impact of this conversion is to show the change between periods exclusive of the effect of fluctuations in exchange rates, which would otherwise distort the change in incurred loss and cash flow patterns shown. The change in incurred loss shown will differ from other U.S. GAAP disclosures of incurred prior period reserve development amounts, which include the effect of fluctuations in exchanges rates. We provided guidance above on key assumptions that should be considered when reviewing this disclosure and information relating to how loss reserve estimates are developed. We believe the information provided in the “Loss Development Tables” section of the disclosure is of limited use for independent analysis or application of standard actuarial estimations. Cumulative Number of Reported Claims Reported claim counts, on a cumulative basis, are provided to the far right of each paid loss development table. We generally consider a reported claim to be one claim per coverage per claimant. We exclude claims closed without payment. Use of the presented claim counts in analysis of company experience has significant limitations, including: • High deductible workers' compensation claim counts include claims below the applicable policy deductible. • Professional liability and certain other lines have a high proportion of claims reported which will be closed without any payment; shifts in total reported counts may not meaningfully impact reported and ultimate loss experience. • Claims for certain events and/or product lines, such as portions of assumed reinsurance and A&H business, are not reported on an individual basis, but rather in bulk and thus not available for inclusion in this disclosure. For certain A&H business, where bulk reporting affected only the oldest few accident years, presented claim counts for these years were estimated. • Each of the segments below typically has a mixture of primary and excess experience which has shifted over time. Reported claim counts include open claims which have case reserves and exclude claims that have been incurred but not reported. As such the reported claims are consistent with reported losses, which can be calculated by subtracting incurred but not reported losses from incurred losses. Reported claim counts are inconsistent with losses in the incurred loss triangle, which include incurred but not reported losses, and are also inconsistent with losses in the paid loss triangle, which exclude case reserves. North America Commercial P&C Insurance — Workers' Compensation — Long-tail During the year ended December 31, 2017, we refined our loss development groupings based on the similarity of loss payout characteristics. The new groupings were applied consistently to all years presented. This product line has a substantial geographic spread and a broad mix across industries. Types of coverage include risk management business predominantly with high deductible policies, loss sensitive business (i.e., retrospectively-rated policies), business fronted for captives, as well as excess and primary guaranteed cost coverages. The triangle below shows all loss and allocated expense development for the workers' compensation product line. In our prior period development disclosure, we exclude any loss development where there is a directly related premium adjustment. For workers' compensation, changes in the exposure base due to payroll audits will drive changes in ultimate losses. In addition, we record involuntary pool assumptions (premiums and losses) on a lagged basis. Both of these items will influence the development in the triangle, particularly the first prior accident year, and are included in the reconciliation table presented on page F-65.

The new groupings were applied consistently to all years presented. This line consists of primary and excess liability exposures, including medical liability, and professional lines, including directors and officers (D&O) liability, errors and omissions (E&O) liability, employment practices liability (EPL), fidelity bonds, and fiduciary liability. The primary and excess liability business represents the largest part of these exposures. The former includes both monoline and commercial package liability. The latter includes a substantial proportion of commercial umbrella, excess and high excess business, where loss activity can produce significant volatility in the loss triangles at later ages within an accident year (and sometimes across years) due to the size of the limits afforded and the complex nature of the underlying losses. This line includes management and professional liability products provided to a wide variety of clients, from national accounts to small firms along with private and not-for-profit organizations, distributed through brokers, agents, wholesalers and MGAs. Many of these coverages, particularly D&O and E&O, are typically written on a claims-made form. While most of the coverages are underwritten on a primary basis, there are significant amounts of excess exposure with large policy limits.

Income Tax Disclosure [Abstract] | |
Taxation | Taxation Under current Swiss law, a resident company is subject to income tax at the federal, cantonal, and communal levels that is levied on net worldwide income. Income attributable to permanent establishments or real estate located abroad is excluded from the Swiss tax base. Chubb Limited is a holding company and, therefore, is exempt from cantonal and communal income tax. As a result, Chubb Limited is subject to Swiss income tax only at the federal level. Furthermore, participation relief (i.e., tax relief) is granted to Chubb Limited at the federal level for qualifying dividend income and capital gains related to the sale of qualifying participations (i.e., subsidiaries). It is expected that the participation relief will result in a full exemption of participation income from federal income tax. Chubb Limited is subject to an annual cantonal and communal capital tax on the taxable equity of Chubb Limited in Switzerland. Chubb has two Swiss operating subsidiaries, an insurance company, Chubb Insurance (Switzerland) Limited and a reinsurance company, Chubb Reinsurance (Switzerland) Limited. Both are subject to federal, cantonal, and communal income tax and to annual cantonal and communal capital tax. Under current Bermuda law, Chubb Limited and its Bermuda subsidiaries are not required to pay any taxes on income or capital gains. If a Bermuda law were enacted that would impose taxes on income or capital gains, Chubb Limited and the Bermuda subsidiaries have received an undertaking from the Minister of Finance in Bermuda that would exempt such companies from Bermudian taxation until March 2035. Income from Chubb's operations at Lloyd's is subject to United Kingdom (U.K.) corporation taxes. Lloyd's is required to pay U.S. income tax on U.S. connected income (U.S. income) written by Lloyd's syndicates. Lloyd's has a closing agreement with the Internal Revenue Service (IRS) whereby the amount of tax due on this business is calculated by Lloyd's and remitted directly to the IRS. These amounts are then charged to the accounts of Chubb's Corporate Members in proportion to their participation in the relevant syndicates. Chubb's Corporate Members are subject to this arrangement but, as U.K. domiciled companies, will receive U.K. corporation tax credits for any U.S. income tax incurred up to the value of the equivalent U.K. corporation income tax charge on the U.S. income. Chubb Group Holdings and its respective subsidiaries are subject to income taxes imposed by U.S. authorities and file a consolidated U.S. tax return. As part of the Chubb Corp acquisition, immediately following the merger, Chubb Corp merged with and into Chubb INA Holdings Inc., and therefore, joined the Chubb Group Holdings consolidated return. Should Chubb Group Holdings pay a dividend to Chubb Limited, withholding taxes would apply. Currently, however, no withholding taxes are accrued with respect to such un-remitted earnings as management has no intention of remitting these earnings. Similarly, no taxes have been provided on the un-remitted earnings of certain foreign subsidiaries (Hong Kong and Korea life companies) as management has no intention of remitting these earnings. The cumulative amount that would be subject to withholding tax, if distributed, as well as the determination of the associated tax liability are not practicable to compute; however, such amount would be material to Chubb. Certain international operations of Chubb are also subject to income taxes imposed by the jurisdictions in which they operate. Chubb's domestic operations are in Switzerland, the jurisdiction where we are legally organized, incorporated, and registered. The following table presents pre-tax income and the related provision for income taxes: Year Ended December 31 (in millions of U.S. dollars) 2017 2016 2015 Pre-tax income: Switzerland $ 527 $ 766 $ 469 Outside Switzerland 3,195 4,184 2,827 Total pre-tax income $ 3,722 $ 4,950 $ 3,296 Provision for income taxes Current tax expense: Switzerland $ 46 $ 97 $ 38 Outside Switzerland 313 727 266 Total current tax expense 359 824 304 Deferred tax expense (benefit): Switzerland 2 (27 ) 4 Outside Switzerland (500 ) 18 154 Total deferred tax expense (benefit) (498 ) (9 ) 158 Provision for income taxes $ (139 ) $ 815 $ 462 The most significant jurisdictions contributing to the overall taxation of Chubb are calculated using the following rates in 2017: Switzerland 7.83 percent , Bermuda 0.0 percent , U.S. 35.0 percent , and U.K. 19.0 percent . Effective January 1, 2018, the U.S. corporate rate was reduced to 21 percent. The following table presents a reconciliation of the difference between the provision for income taxes and the expected tax provision at the Swiss statutory income tax rate: Year Ended December 31 (in millions of U.S. dollars) 2017 2016 2015 Expected tax provision at Swiss statutory tax rate $ 291 $ 388 $ 258 Permanent differences: Taxes on earnings subject to rate other than Swiss statutory rate 263 582 193 Tax-exempt interest and dividends received deduction, net of proration (199 ) (200 ) (32 ) Net withholding taxes 30 20 35 Excess tax benefit on share-based compensation (48 ) — — Impact of 2017 Tax Act (450 ) — — Corporate owned life insurance (37 ) — — Other 11 25 8 Total provision for income taxes $ (139 ) $ 815 $ 462 The following table presents the components of net deferred tax assets and liabilities: December 31 December 31 (in millions of U.S. dollars) 2017 2016 Deferred tax assets: Loss reserve discount $ 715 $ 1,269 Unearned premiums reserve 231 498 Foreign tax credits 340 2,115 Provision for uncollectible balances 45 72 Loss carry-forwards 90 92 Debt related amounts 77 219 Compensation related amounts 260 449 Cumulative translation adjustments 30 59 Other, net 70 69 Total deferred tax assets 1,858 4,842 Deferred tax liabilities: Deferred policy acquisition costs 635 842 Other intangible assets, including VOBA 1,437 2,352 Un-remitted foreign earnings 66 2,001 Investments 53 406 Unrealized appreciation on investments 184 60 Depreciation 83 91 Total deferred tax liabilities 2,458 5,752 Valuation allowance 99 78 Net deferred tax assets (liabilities) $ (699 ) $ (988 ) The 2017 Tax Act, enacted on December 22, 2017, among other things, reduces the U.S. federal income tax rate to 21 percent from 35 percent effective in 2018. We have not completed our assessment of the effects of the 2017 Tax Act; however, we have made our best estimate of those effects based on our current understanding of the provisions in the Act. Accordingly, we recorded a $450 million income tax transition benefit in the fourth quarter of 2017 on a provisional basis, principally reflecting the reduction in the U.S. corporate tax rate from 35 percent to 21 percent . This is comprised of a $743 million reduction in the deferred tax liabilities principally related to certain intangible assets, a $371 million reduction in net deferred tax assets related to other net assets, and a net benefit of $78 million related to the impact of excess foreign tax credits generated by the deemed repatriation rules and the impact of the reduced rate on our foreign branches. We have computed these amounts based on the best available information and our understanding of the 2017 Tax Act. As we complete our analysis of the 2017 Tax Act, collect and prepare necessary data and interpret any additional guidance issued by the IRS, the Treasury Department and other standard setting agencies, we may make adjustments to the provisional amounts. Those adjustments may materially impact our provision for income taxes in the period in which the adjustments are made. The valuation allowance of $ 99 million at December 31, 2017 , and $ 78 million at December 31, 2016 , reflects management's assessment, based on available information, that it is more likely than not that a portion of the deferred tax assets will not be realized due to the potential inability to utilize foreign tax credits in the U.S. and the inability of certain foreign subsidiaries to generate sufficient taxable income. Adjustments to the valuation allowance are made when there is a change in management's assessment of the amount of deferred tax assets that are realizable. At December 31, 2017 , Chubb has net operating loss carry-forwards of $ 329 million which, if unused, will expire starting in 2018, and a foreign tax credit carry-forward in the amount of $ 340 million which, if unused, will expire in the years 2022 through 2027. The following table presents a reconciliation of the beginning and ending amount of gross unrecognized tax benefits: December 31 December 31 (in millions of U.S. dollars) 2017 2016 Balance, beginning of year $ 17 $ 16 Additions based on tax positions related to the current year 3 3 Additions based on tax positions related to prior years (1) — 2 Reductions for tax positions of prior years (4 ) (4 ) Reductions for the lapse of the applicable statutes of limitations (3 ) — Balance, end of year $ 13 $ 17 (1) Assumed in connection with the Chubb Corp acquisition in 2016. At December 31, 2017 and 2016 , the total amount of unrecognized tax benefits that would affect the effective tax rate, if recognized, were $13 million and $ 17 million , respectively. Chubb recognizes accruals for interest and penalties, if any, related to unrecognized tax benefits in income tax expense in the Consolidated statements of operations. For the years ended December 31, 2017 , 2016 , and 2015 , tax-related interest expense (income) and penalties reported in the Consolidated statements of operations was $1 million for each of the three years. At December 31, 2017 and 2016 , liabilities for tax-related interest and penalties in our Consolidated balance sheets were $ 3 million and $4 million , respectively. In September 2016, the IRS completed its examination of Chubb Group Holdings’ (formerly ACE Group Holdings) federal tax returns for the 2010-2012 tax years. No material adjustments resulted from this examination. During 2017, the IRS commenced its field examination of Chubb Group Holdings federal income tax returns for 2014 and 2015 and Chubb Corp’s federal tax return for 2014 which were still ongoing at December 31, 2017. 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 and the closing of tax statutes of limitations. With few exceptions, Chubb is no longer subject to state and local and non-U.S. income tax examinations for years before 2010. |

(2) Redemption prices are equal to accrued and unpaid interest to the redemption date plus the greater of (i) 100 percent of the principal amount thereof, or (ii) sum of present value of scheduled payments of principal and interest on the capital securities from the redemption date to April 1, 2030. a) Repurchase agreements Chubb has executed repurchase agreements with certain counterparties under which Chubb agreed to sell securities and repurchase them at a future date for a predetermined price. b) Short-term debt Short-term debt comprises the current maturities of our long-term debt instruments described below. These short-term debt instruments were reclassified from long-term debt during 2017 and are reflected in the table above. c) Long-term debt Certain of Chubb INA's senior notes and capital securities are redeemable at any time at Chubb INA's option subject to the provisions described in the table above. A "make-whole" premium is the present value of the remaining principal and interest discounted at the applicable U.S. Treasury rate. The senior notes and capital securities are also redeemable at par plus accrued and unpaid interest in the event of certain changes in tax law. The senior notes do not have the benefit of any sinking fund. These senior unsecured notes are guaranteed on a senior basis by Chubb Limited and they rank equally with all of Chubb'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. We have outstanding $ 1.0 billion of unsecured junior subordinated capital securities at December 31, 2017 , which were assumed by Chubb INA in connection with the Chubb Corp acquisition. Effective April 15, 2017, the interest rate on our $1.0 billion of unsecured junior subordinated capital securities converted to a floating rate, equal to the three-month LIBOR plus 2.25 percentage points. Previously, these capital securities carried interest at a rate of 6.375 percent. The current interest rate at the time of this filing on these securities is 3.97 percent . The scheduled maturity date for these securities is April 15, 2037. In August 2017, Chubb eliminated the Replacement Capital Covenant (RCC) associated with these capital securities which benefited the holders of the 6.8 percent debentures due November 2031. The RCC was eliminated through a consent solicitation process whereby the holders of the 6.8 percent debentures agreed to waive their rights under the RCC in exchange for a nominal fee. Chubb received the requisite number of consents required to eliminate the RCC and as a result, the RCC was terminated in August 2017. d) Trust preferred securities In March 2000, ACE Capital Trust II, a Delaware statutory business trust, publicly issued $ 300 million of 9.7 percent Capital Securities (the Capital Securities) due to mature in April 2030. At the same time, Chubb INA purchased $ 9.2 million of common securities of ACE Capital Trust II. The sole assets of ACE Capital Trust II consist of $ 309 million principal amount of 9.7 percent Junior Subordinated Deferrable Interest Debentures (the Subordinated Debentures) issued by Chubb INA due to mature in April 2030. Distributions on the Capital Securities are payable semi-annually and may be deferred for up to ten consecutive semi-annual periods (but no later than April 1, 2030). Any deferred payments would accrue interest compounded semi-annually if Chubb INA defers interest on the Subordinated Debentures. Interest on the Subordinated Debentures is payable semi-annually. Chubb INA may defer such interest payments (but no later than April 1, 2030), with such deferred payments accruing interest compounded semi-annually. The Capital Securities and the ACE Capital Trust II Common Securities will be redeemed upon repayment of the Subordinated Debentures. Chubb Limited has guaranteed, on a subordinated basis, Chubb INA's obligations under the Subordinated Debentures, and distributions and other payments due on the Capital Securities. These guarantees, when taken together with Chubb's obligations under expense agreements entered into with ACE Capital Trust II, provide a full and unconditional guarantee of amounts due on the Capital Securities. |

Commitments and Contingencies Disclosure [Abstract] | |
Commitments, contingencies, and guarantees | Commitments, contingencies, and guarantees a) Derivative instruments Foreign currency management As a global company, Chubb entities transact business in multiple currencies. Our policy is to generally match assets, liabilities, and required capital for each individual jurisdiction in local currency, which would include the use of derivatives discussed below. We do not hedge our net asset non-U.S. dollar capital positions; however, we do consider economic hedging for planned cross border transactions. Derivative instruments employed Chubb 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. Chubb also maintains positions in convertible securities that contain embedded derivatives. Investment derivative instruments are recorded in either Other assets (OA) or Accounts payable, accrued expenses, and other liabilities (AP), convertible bonds are recorded in Fixed maturities available for sale (FM AFS), and convertible equity securities are recorded in Equity securities (ES) in the Consolidated balance sheets. These are the most numerous and frequent derivative transactions. In addition, Chubb from time to time purchases to be announced mortgage-backed securities (TBAs) as part of its investing activities. Under reinsurance programs covering GLBs, Chubb assumes the risk of GLBs, including GMIB and GMAB, associated with variable annuity contracts. The GMIB risk is triggered if, at the time the contract holder elects to convert the accumulated account value to a periodic payment stream (annuitize), the accumulated account value is not sufficient to provide a guaranteed minimum level of monthly income. The GMAB risk is triggered if, at contract maturity, the contract holder’s account value is less than a guaranteed minimum value. The GLB reinsurance product meets the definition of a derivative instrument. Benefit reserves in respect of GLBs are classified as Future policy benefits (FPB) while the fair value derivative adjustment is classified within AP. Chubb also generally maintains positions in exchange-traded equity futures contracts on equity market indices to limit equity exposure in the GMDB and GLB blocks of business. 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. The following table presents the balance sheet locations, fair values of derivative instruments in an asset or (liability) position, and notional values/payment provisions of our derivative instruments: December 31, 2017 December 31, 2016 Consolidated Fair Value Notional Fair Value Notional Derivative Asset Derivative (Liability) Derivative Asset Derivative (Liability) (in millions of U.S. dollars) Investment and embedded derivative instruments: Foreign currency forward contracts OA / (AP) $ 14 $ (27 ) $ 2,064 $ 25 $ (50 ) $ 2,220 Cross-currency swaps OA / (AP) — — 45 — — 95 Options/Futures contracts on notes and bonds OA / (AP) 4 (3 ) 1,007 6 (4 ) 2,344 Convertible securities (1) FM AFS/ES 5 — 6 2 — 7 $ 23 $ (30 ) $ 3,122 $ 33 $ (54 ) $ 4,666 Other derivative instruments: Futures contracts on equities (2) OA / (AP) $ — $ (21 ) $ 1,553 $ 1 $ — $ 1,316 Other OA / (AP) 1 (2 ) 75 2 (13 ) 214 $ 1 $ (23 ) $ 1,628 $ 3 $ (13 ) $ 1,530 GLB (3) (AP) / (FPB) $ — $ (550 ) $ 1,083 $ — $ (853 ) $ 1,264 (1) Includes fair value of embedded derivatives. (2) Related to GMDB and GLB blocks of business. (3) Includes both future policy benefits reserves and fair value derivative adjustment. Refer to Note 5 c ) for additional information. Note that the payment provision related to GLB is the net amount at risk. The concept of a notional value does not apply to the GLB reinsurance contracts. At December 31, 2017 and 2016 , derivative liabilities of $ 24 million and $10 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. b) Secured borrowings Chubb participates in a securities lending program operated by a third-party banking institution whereby certain assets are loaned to qualified borrowers and from which we earn an incremental return. At December 31, 2017 and 2016 , our securities lending collateral was $1,737 million and $1,092 million , respectively, and our securities lending payable, reflecting our obligation to return the collateral plus interest, was $1,737 million and $1,093 million , respectively. The securities lending collateral can only be drawn down by Chubb 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. The collateral is recorded in Securities lending collateral and the liability is recorded in Securities lending payable in the Consolidated balance sheets. The following table presents the carrying value of collateral held under securities lending agreements by investment category and remaining contractual maturity of the underlying agreements: Remaining contractual maturity December 31 2017 December 31 2016 (in millions of U.S. dollars) Overnight and Continuous Collateral held under securities lending agreements: Cash $ 828 $ 423 U.S. Treasury and agency 36 54 Foreign 712 578 Corporate securities — 37 Mortgage-backed securities 74 — Equity securities 87 — $ 1,737 $ 1,092 Gross amount of recognized liability for securities lending payable $ 1,737 $ 1,093 Difference (1) $ — $ (1 ) (1) The carrying value of the securities lending collateral held is $1 million lower than the securities lending payable at December 31, 2016 due to accrued interest recorded in the securities lending payable. At December 31, 2017 and 2016 , our repurchase agreement obligations of $1,408 million and $ 1,403 million , respectively, were fully collateralized. In contrast to securities lending programs, the use of cash received is not restricted for the repurchase obligations. The fair value of the underlying securities sold remains in Fixed maturities available for sale, and the repurchase agreement obligation is recorded in Repurchase agreements in the Consolidated balance sheets. The following table presents the carrying value of collateral pledged under repurchase agreements by investment category and remaining contractual maturity of the underlying agreements: Remaining contractual maturity December 31, 2017 December 31, 2016 Up to 30 Days Greater than 90 Days Up to 30 Days Greater than 90 Days Total (in millions of U.S. dollars) Total Collateral pledged under repurchase agreements: Cash $ — $ — $ — $ — $ 1 $ 1 U.S. Treasury and agency 9 230 239 230 10 240 Mortgage-backed securities 369 826 1,195 339 881 1,220 $ 378 $ 1,056 $ 1,434 $ 569 $ 892 $ 1,461 Gross amount of recognized liabilities for repurchase agreements $ 1,408 $ 1,403 Difference (1) $ 26 $ 58 (1) Per the repurchase agreements, the amount of collateral posted is required to exceed the amount of gross liability. Potential risks exist in our secured borrowing transactions due to market conditions and counterparty exposure. With collateral that we pledge, there is a risk that the collateral may not be returned at the expiration of the agreement. If the counterparty fails to return the collateral, Chubb will have free use of the borrowed funds until our collateral is returned. In addition, we may encounter the risk that Chubb may not be able to renew outstanding borrowings with a new term or with an existing counterparty due to market conditions including a decrease in demand as well as more restrictive terms from banks due to increased regulatory and capital constraints. Should this condition occur, Chubb may seek alternative borrowing sources or reduce borrowings. Additionally, increased margins and collateral requirements due to market conditions would increase our restricted assets as we are required to provide additional collateral to support the transaction. The following table presents net realized gains (losses) related to derivative instrument activity in the Consolidated statements of operations: Year Ended December 31 (in millions of U.S. dollars) 2017 2016 2015 Investment and embedded derivative instruments: Foreign currency forward contracts $ 9 $ (31 ) $ 31 All other futures contracts and options (21 ) (10 ) 9 Convertible securities (1) 1 8 (8 ) Total investment and embedded derivative instruments $ (11 ) $ (33 ) $ 32 GLB and other derivative instruments: GLB (2) $ 364 $ 53 $ (203 ) Futures contracts on equities (3) (261 ) (136 ) (8 ) Other (5 ) (10 ) (14 ) Total GLB and other derivative instruments $ 98 $ (93 ) $ (225 ) $ 87 $ (126 ) $ (193 ) (1) Includes embedded derivatives. (2) Excludes foreign exchange gains (losses) related to GLB. (3) Related to GMDB and GLB blocks of business. c) 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. Chubb uses forwards to minimize the effect of fluctuating foreign currencies as discussed above. (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, an increase in 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. The price of an option is influenced by the underlying security, expected volatility, time to expiration, and supply and demand. The credit risk associated with the above derivative financial instruments relates to the potential for non-performance by counterparties. Although non-performance is not anticipated, in order to minimize the risk of loss, management monitors the creditworthiness of its counterparties and obtains collateral. The performance of exchange-traded instruments is guaranteed by the exchange on which they trade. For non-exchange-traded instruments, the counterparties are principally banks which must meet certain criteria according to our investment guidelines. Cross-currency swaps Cross-currency swaps are agreements under which two counterparties exchange interest payments and principal denominated in different currencies at a future date. We use cross-currency swaps to reduce the foreign currency and interest rate risk by converting cash flows back into local currency. We invest in foreign currency denominated investments to improve credit diversification and also to obtain better duration matching to our liabilities that is limited in the local currency market. Other Included within Other are derivatives intended to reduce potential losses which may arise from certain exposures in our insurance business. The economic benefit provided by these derivatives is similar to purchased reinsurance. For example, Chubb may enter into crop derivative contracts to protect underwriting results in the event of a significant decline in commodity prices. (iii) Convertible security investments A convertible security is a debt instrument or preferred stock that can be converted into a predetermined amount of the issuer’s equity. The convertible option is an embedded derivative within the host instruments which are classified in the investment portfolio as either available for sale or as an equity security. Chubb purchases convertible securities for their total return and not specifically for the conversion feature. (iv) TBA By acquiring TBAs, we make a commitment to purchase a future issuance of mortgage-backed securities. For the period between purchase of the TBAs and issuance of the underlying security, we account for our position as a derivative in the consolidated financial statements. Chubb 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, Chubb 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 an 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. d) Concentrations of credit risk Our investment portfolio is managed following prudent standards of diversification. Specific provisions limit the allowable holdings of a single issue and issuer. We believe that there are no significant concentrations of credit risk associated with our investments. Our three largest exposures by issuer at December 31, 2017 , were Wells Fargo & Co., JP Morgan Chase & Co., and Anheuser-Busch InBev NV. Our largest exposure by industry at December 31, 2017 was financial services. We market our insurance and reinsurance worldwide primarily through insurance and reinsurance brokers. We assume a degree of credit risk associated with brokers with whom we transact business. No broker or one insured accounted for more than 10 percent of gross written premium for the years ended December 31, 2017, 2016, and 2015. e) Fixed maturities At December 31, 2017 , we have commitments to purchase fixed income securities of $1,020 million over the next several years. f) Other investments At December 31, 2017 , included in Other investments in the Consolidated balance sheet are investments in limited partnerships and partially-owned investment companies with a carrying value of $3.4 billion. In connection with these investments, we have commitments that may require funding of up to $4.1 billion over the next several years. g) Letters of credit On October 25, 2017, we replaced our $1.5 billion letter of credit/revolver facility that was set to expire in November 2017 with an amended and restated credit facility that provides for up to $1.0 billion of availability, all of which may be used for the issuance of letters of credit and for revolving loans. We have the ability to increase the capacity under our existing credit facility to $2.0 billion under certain conditions, but any such increase would not raise the sub-limit for revolving loans above $1.0 billion . The letter of credit facility required that we maintain certain financial covenants, all of which we met at December 31, 2017 . At December 31, 2017, outstanding LOCs issued under this facility were $250 million . h) Legal proceedings Our insurance subsidiaries are subject to claims litigation involving disputed interpretations of policy coverages and, in some jurisdictions, direct actions by allegedly-injured persons seeking damages from policyholders. These lawsuits, involving claims on policies issued by our subsidiaries which are typical to the insurance industry in general and in the normal course of business, are considered in our loss and loss expense reserves. In addition to claims litigation, we are subject to lawsuits and regulatory actions in the normal course of business that do not arise from or directly relate to claims on insurance policies. This category of business litigation typically involves, among other things, allegations of underwriting errors or misconduct, employment claims, regulatory activity, or disputes arising from our business ventures. In the opinion of management, our ultimate liability for these matters could be, but we believe is not likely to be, material to our consolidated financial condition and results of operations. i) Lease commitments We lease office space and equipment under operating leases which expire at various dates through 2033. Rent expense was $ 211 million, $ 209 million, and $ 126 million for the years ended December 31, 2017 , 2016 , and 2015 , respectively. Future minimum lease payments under the leases are expected to be as follows: For the years ending December 31 (in millions of U.S. dollars) 2018 $ 181 2019 153 2020 133 2021 114 2022 89 Thereafter 230 Total minimum future lease commitments $ 900 |

Stockholders' Equity Note [Abstract] | |
Shareholders' equity | Shareholders’ equity a) Common Shares All of Chubb’s Common Shares are authorized under Swiss corporate law. Though the par value of Common Shares is stated in Swiss francs, Chubb continues to use U.S. dollars as its reporting currency for preparing the consolidated financial statements. Under Swiss corporate law, we are generally prohibited from issuing Common Shares below their par value. If there were a need to raise common equity at a time when the trading price of Chubb's Common Shares is below par value, we would need in advance to obtain shareholder approval to decrease the par value of the Common Shares. Dividend approval At our May 2016 and 2015 annual general meetings, our shareholders approved an annual dividend for the following year of up to $2.76 and $2.68 per share, respectively, which was paid in four quarterly installments of $0.69 per share and $0.67 per share, respectively, at dates determined by the Board of Directors (Board) after the annual general meeting by way of a distribution from capital contribution reserves, transferred to free reserves for payment. At our May 2017 annual general meeting, our shareholders approved an annual dividend for the following year of up to $ 2.84 per share, expected to be paid in four quarterly installments of $ 0.71 per share after the annual general meeting by way of distribution from capital contribution reserves, transferred to free reserves for payment. The Board will determine the record and payment dates at which the annual dividend may be paid until the date of the 2018 annual general meeting, and is authorized to abstain from distributing a dividend at its discretion. The first three quarterly installments each of $ 0.71 per share, have been distributed by the Board as expected. Dividend distributions Under Swiss corporate law, dividends, including distributions through a reduction in par value (par value reduction), must be stated in Swiss francs though dividend payments are made by Chubb in U.S. dollars. Dividend distributions following Chubb's redomestication to Switzerland have generally been made by way of par value reduction (under the methods approved by our shareholders at our annual general meetings) and had the effect of reducing par value per Common Share each time a dividend was distributed. We may also issue dividends without subjecting them to withholding tax by way of distributions from capital contribution reserves and payment out of free reserves. We employed this method of dividends for the annual dividends approved in May 2015, 2016 and 2017 as noted above. The following table presents dividend distributions per Common Share in Swiss francs (CHF) and U.S. dollars (USD): Year Ended December 31 2017 2016 2015 CHF USD CHF USD CHF USD Dividends - par value reduction — $ — — $ — 0.62 $ 0.65 Dividends - distributed from capital contribution reserves 2.76 2.82 2.70 2.74 1.94 2.01 Total dividend distributions per common share 2.76 $ 2.82 2.70 $ 2.74 2.56 $ 2.66 b) Shares issued, outstanding, authorized, and conditional Year Ended December 31 2017 2016 2015 Shares issued, beginning of year 479,783,864 342,832,412 342,832,412 Shares issued for Chubb Corp acquisition — 136,951,452 — Shares issued, end of year 479,783,864 479,783,864 342,832,412 Common Shares in treasury, end of year (at cost) (15,950,685 ) (13,815,148 ) (18,268,971 ) Shares issued and outstanding, end of year 463,833,179 465,968,716 324,563,441 Increases in Common Shares in treasury are due to open market repurchases of Common Shares and the surrender of Common Shares to satisfy tax withholding obligations in connection with the vesting of restricted stock and the forfeiture of unvested restricted stock. Decreases in Common Shares in treasury are principally due to grants of restricted stock, exercises of stock options, and purchases under the Employee Stock Purchase Plan (ESPP). Authorized share capital for general purposes The Board has shareholder-approved authority as set forth in the Articles of Association to increase for general purposes Chubb's share capital from time to time until May 19, 2018, by the issuance of up to 200,000,000 fully paid up Common Shares, with a par value equal to the par value of Chubb's Common Shares as set forth in the Articles of Association at the time of any such issuance. Chubb intends to seek shareholder approval at its 2018 annual general meeting for a new pool of authorized share capital for general purposes to replace the existing 200,000,000 share pool when it expires. Conditional share capital for bonds and similar debt instruments Chubb's share capital may be increased through the issuance of a maximum of 33,000,000 fully paid up Common Shares (with a par value of CHF 24.15 as of December 31, 2017) through the exercise of conversion and/or option or warrant rights granted in connection with bonds, notes, or similar instruments, issued or to be issued by Chubb, including convertible debt instruments. Conditional share capital for employee benefit plans Chubb's share capital may be increased through the issuance of a maximum of 25,410,929 fully paid up Common Shares (with a par value of CHF 24.15 as of December 31, 2017) in connection with the exercise of option rights granted to any employee of Chubb, and any consultant, director, or other person providing services to Chubb. c) Chubb Limited securities repurchases From time to time, we repurchase shares as part of our capital management program and to partially offset potential dilution from the exercise of stock options and the granting of restricted stock under share-based compensation plans. Our Board of Directors has authorized share repurchase programs as follows: • $ 1.5 billion of Chubb Common Shares from January 1, 2015 through December 31, 2015 • $ 1.0 billion of Chubb Common Shares from November 17, 2016 through December 31, 2017 • $1.0 billion of Chubb Common Shares from January 1, 2018 through December 31, 2018 Share repurchases may be in the open market, in privately negotiated transactions, block trades, accelerated repurchases and/or through option or other forward transactions. The following table presents repurchases of Chubb's Common Shares conducted in a series of open market transactions under the Board authorizations: Year Ended December 31 (in millions of U.S. dollars, except share data) 2017 2016 2015 Number of shares repurchased 5,866,612 — 6,677,663 Cost of shares repurchased $ 830 $ — $ 734 d) General restrictions The holders of the Common Shares are entitled to receive dividends as approved by the shareholders. Holders of Common Shares are allowed one vote per share provided that, if the controlled shares of any shareholder constitute ten percent or more of the outstanding Common Shares of Chubb, only a fraction of the vote will be allowed so as not to exceed ten percent in aggregate. Entry of acquirers of Common Shares as shareholders with voting rights in the share register may be refused if it would confer voting rights with respect to ten percent or more of the registered share capital recorded in the commercial register. |

Disclosure of Compensation Related Costs, Share-based Payments [Abstract] | |
Share-based compensation | Share-based compensation Chubb has share-based compensation plans which currently provide the Board the ability to grant awards of stock options, restricted stock, and restricted stock units to its employees, consultants, and members of the Board. In connection with the Chubb Corp acquisition in 2016, we assumed outstanding equity awards consisting of service-based restricted stock units, performance-based restricted stock units, and stock options issued by Chubb Corp to employees and directors with a fair value of $525 million , of which $323 million is attributed to purchase consideration for the acquisition. These awards were generally granted with a 3-year vesting period, and the stock options generally have a 10-year term. In May 2016, our shareholders approved the Chubb Limited 2016 Long-Term Incentive Plan (the 2016 LTIP), which replaced both the ACE Limited 2004 LTIP (the 2004 LTIP) and The Chubb Corporation Long-Term Incentive Plan (2014). The 2016 LTIP is substantially similar to the 2004 LTIP in its operation and the types of awards that may be granted. Under the 2016 LTIP, Common Shares of Chubb were authorized to be issued pursuant to awards made as stock options, stock appreciation rights, performance shares, performance units, restricted stock, and restricted stock units. Chubb principally issues restricted stock grants and stock options on a graded vesting schedule. Chubb recognizes compensation cost for restricted stock and stock option grants with only service conditions that have a graded vesting schedule on a straight-line basis over the requisite service period for each separately vesting portion of the award as if the award was, in-substance, multiple awards. We incorporate an estimate of future forfeitures ( 6.5 percent assumption used for grants made in 2017, 2016, and 2015) in determining compensation cost for both grants of restricted stock and stock options. Chubb generally grants restricted stock and restricted stock units with a 4 -year vesting period, which vest in equal annual installments over the respective vesting period. The restricted stock is granted at market close price on the day of grant. Each restricted stock unit represents our obligation to deliver to the holder one Common Share upon vesting. Under the 2016 LTIP, 19,500,000 Common Shares were authorized to be issued, in addition to any shares that have not been delivered pursuant to the 2004 LTIP and remain available for grant pursuant to the 2004 LTIP, including any shares covered by awards granted under the 2004 LTIP that are forfeited, expire or are canceled after the effective date of the 2016 LTIP without delivery of shares or which result in the forfeiture of the shares back to Chubb. At December 31, 2017, a total of 17,065,705 shares remain available for future issuance under the 2016 LTIP, which includes shares canceled or forfeited from the 2004 LTIP, in addition to common shares that were previously registered and authorized to be issued. In May 2017, our shareholders approved an increase of 2,000,000 shares authorized to be issued under the Employee Stock Purchase Plan (ESPP), bringing the total shares authorized to 6,500,000 shares. At December 31, 2017, a total of 2,452,058 shares remain available for issuance under the ESPP. Chubb generally issues Common Shares for the exercise of stock options, restricted stock, and purchases under the ESPP from un-issued reserved shares (conditional share capital) and Common Shares in treasury. The following table presents pre-tax and after-tax share-based compensation expense: Year Ended December 31 (in millions of U.S. dollars) 2017 2016 2015 Stock options and shares issued under ESPP: Pre-tax $ 41 $ 33 $ 31 After-tax (1) $ 26 $ 20 $ 21 Restricted stock: Pre-tax $ 259 $ 268 $ 143 After-tax $ 151 $ 167 $ 84 (1) Excludes windfall tax benefit for share-based compensation recognized as a direct adjustment to Additional paid-in capital of $32 million and $26 million for the years ended December 31, 2016 and 2015, respectively. Due to the adoption of new accounting guidance, windfall tax benefits for share-based compensation beginning in 2017 are recognized through Net income rather than Additional paid-in capital. The excess tax benefit recorded to Income tax expense in the Consolidated statement of operations was $48 million for the year ended December 31, 2017. Unrecognized compensation expense related to the unvested portion of Chubb's employee share-based awards was $345 million at December 31, 2017 , and is expected to be recognized over a weighted-average period of approximately 1 year. Stock options Both incentive and non-qualified stock options are principally granted at an option price per share equal to the grant date fair value of Chubb's Common Shares. Stock options are generally granted with a 3 -year vesting period and a 10 -year term. Stock options vest in equal annual installments over the respective vesting period, which is also the requisite service period. Chubb's 2017 share-based compensation expense includes a portion of the cost related to the 2014 through 2017 stock option grants. Stock option fair value was estimated on the grant date using the Black-Scholes option-pricing model that uses the weighted-average assumptions noted below: Year Ended December 31 2017 2016 2015 Dividend yield 2.0 % 2.3 % 2.3 % Expected volatility 19.7 % 23.2 % 21.0 % Risk-free interest rate 2.0 % 1.3 % 1.7 % Expected life 5.8 years 5.6 years 5.8 years The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant. The expected life (estimated period of time from grant to exercise date) was estimated using the historical exercise behavior of employees. Expected volatility was calculated as a blend of (a) historical volatility based on daily closing prices over a period equal to the expected life assumption, (b) long-term historical volatility based on daily closing prices over the period from Chubb's initial public trading date through the most recent quarter, and (c) implied volatility derived from Chubb's publicly traded options. The following table presents a roll-forward of Chubb's stock options: (Intrinsic Value in millions of U.S. dollars) Number of Options Weighted-Average Exercise Price Weighted-Average Fair Value Total Intrinsic Value Options outstanding, December 31, 2014 9,623,986 $ 69.06 Granted 1,892,641 $ 114.78 $ 18.49 Exercised (1,457,580 ) $ 60.88 $ 72 Forfeited (205,551 ) $ 100.25 Options outstanding, December 31, 2015 9,853,496 $ 78.40 Assumed in Chubb Corp Acquisition 339,896 $ 77.83 $ 36.07 Granted 1,929,616 $ 118.39 $ 21.52 Exercised (1,728,949 ) $ 66.65 $ 99 Forfeited (213,339 ) $ 110.01 Options outstanding, December 31, 2016 10,180,720 $ 87.29 Granted 2,079,522 $ 139.00 $ 22.97 Exercised (1,632,629 ) $ 73.53 $ 111 Forfeited (194,297 ) $ 119.44 Options outstanding, December 31, 2017 10,433,316 $ 99.20 $ 490 Options exercisable, December 31, 2017 6,675,491 $ 82.59 $ 424 The weighted-average remaining contractual term was 6.2 years for stock options outstanding and 4.8 years for stock options exercisable at December 31, 2017 . Cash received from the exercise of stock options for the year ended December 31, 2017 was $133 million . Restricted stock and restricted stock units Grants of restricted stock and restricted stock units awarded under both the 2004 LTIP and 2016 LTIP typically have a 4-year vesting period, based on a graded vesting schedule. Chubb grants performance-based restricted stock to certain executives that vest based on tangible book value (shareholders' equity less goodwill and intangible assets, net of tax) per share growth compared to a defined group of peer companies. The performance-based stock awards comprise target awards which have four installments that vest annually based on the performance criteria, and premium awards, which are earned only if tangible book value per share growth over the cumulative 4-year period after the grant of the associated target awards exceeds a higher threshold compared to our peer group. Shares representing target awards are issued when the performance award is approved. They are subject to forfeiture if applicable performance criteria are not met. For awards granted prior to February 2014, shares representing premium awards were not issued at the time the target award was approved. Rather, they were subject to issuance following the 4-year performance period, if and to the extent the premium awards were earned. For awards granted in February 2014 and thereafter, premium awards have been issued subject to vesting if actually earned or forfeited if not earned at the end of the 4-year performance period. The terms of performance-based restricted stock awards granted beginning in January 2017 were updated to now include a 3-year cliff vesting provision in place of the 4-year graded vesting period. In addition, these awards now include an additional vesting criteria based on the P&C combined ratio compared to a defined group of peer companies as well as an additional vesting provision based on total shareholder return (TSR) compared to a defined group of peer companies. Chubb also grants restricted stock awards to non-management directors which vest at the following year's annual general meeting. The restricted stock is granted at market close price on the grant date. Each restricted stock unit represents our obligation to deliver to the holder one Common Share upon vesting. Chubb's 2017 share-based compensation expense includes a portion of the cost related to the restricted stock granted in the years 2013 through 2017. The following table presents a roll-forward of our restricted stock awards. Included in the roll-forward below are 22,013 restricted stock awards, 23,812 restricted stock awards, and 24,945 restricted stock awards that were granted to non-management directors during the years ended December 31, 2017 , 2016 , and 2015 , respectively: Service-based Restricted Stock Awards and Restricted Stock Units Performance-based Restricted Stock Awards and Restricted Stock Units Number of Shares Weighted-Average Grant-Date Fair Value Number of Shares Weighted-Average Grant-Date Fair Value Unvested restricted stock, December 31, 2014 3,837,097 $ 83.60 378,690 $ 90.87 Granted 1,417,965 $ 114.37 326,860 $ 113.29 Vested (1,341,358 ) $ 80.05 (110,340 ) $ 98.70 Forfeited (424,535 ) $ 87.36 — $ — Unvested restricted stock, December 31, 2015 3,489,169 $ 97.01 595,210 $ 101.73 Assumed in Chubb Corp Acquisition 3,706,639 $ 111.02 — $ — Granted 1,622,065 $ 118.70 517,507 $ 118.96 Vested (2,592,622 ) $ 100.87 (181,548 ) $ 102.43 Forfeited (420,125 ) $ 109.42 — $ — Unvested restricted stock, December 31, 2016 5,805,126 $ 109.39 931,169 $ 111.17 Granted 1,707,094 $ 139.18 267,282 $ 138.90 Vested (2,646,084 ) $ 107.73 (222,954 ) $ 113.30 Forfeited (156,694 ) $ 114.54 — $ — Unvested restricted stock, December 31, 2017 4,709,422 $ 121.16 975,497 $ 118.28 Prior to 2009, legacy ACE granted restricted stock units with a 1 -year vesting period to non-management directors. Delivery of Common Shares on account of these restricted stock units to non-management directors is deferred until after the date of the non-management directors' termination from the Board. Legacy Chubb Corp historically allowed directors and certain key employees of Chubb Corp and its subsidiaries to defer a portion of their compensation earned with respect to services performed in the form of deferred stock units. In addition, legacy Chubb Corp provides supplemental retirement benefits for certain employees through its Defined Contribution Excess Benefit Plan in the form of deferred shares of stock. The minimum vesting period under these legacy Chubb Corp deferred plans is 1-year and the maximum is 3-years. Employees and directors had the option to elect to receive their awards at a future specified date or upon their termination of service with Chubb. At December 31, 2017 , there were 279,986 deferred restricted stock units. ESPP The ESPP gives participating employees the right to purchase Common Shares through payroll deductions during consecutive subscription periods at a purchase price of 85 percent of the fair value of a Common Share on the exercise date (Purchase Price). Annual purchases by participants are limited to the number of whole shares that can be purchased by an amount equal to ten percent of the participant's compensation or $ 25,000 , whichever is less. The ESPP has two six-month subscription periods each year, the first of which runs between January 1 and June 30 and the second of which runs between July 1 and December 31. Legacy Chubb Corp employees were eligible to participate in the ESPP beginning in the July 1 to December 31 subscription period of 2016. The amounts collected from participants during a subscription period are used on the exercise date to purchase full shares of Common Shares. An exercise date is generally the last trading day of a subscription period. The number of shares purchased is equal to the total amount, at the exercise date, collected from the participants through payroll deductions for that subscription period, divided by the Purchase Price, rounded down to the next full share. Participants may withdraw from an offering before the exercise date and obtain a refund of amounts withheld through payroll deductions. Pursuant to the provisions of the ESPP, during the years ended December 31, 2017 , 2016 , and 2015 , employees paid $34 million , $ 24 million, and $ 18 million to purchase 271,185 shares, 211,492 shares, and 197,442 shares, respectively. |

Retirement Benefits [Abstract] | |
Postretirement benefits | Postretirement benefits Chubb provides postretirement benefits to eligible employees and their dependents through various defined contribution plans and defined benefit plans sponsored by Chubb. With the acquisition, Chubb assumed the outstanding pension and other postretirement benefit plan obligations of Chubb Corp, which consisted of several non-contributory defined benefit pension plans covering substantially all its employees, and several other postretirement benefit plans to retired employees. After the acquisition, Chubb also sponsors the defined contribution plans covering Chubb Corp employees. Defined benefit pension plans We maintain non-contributory defined benefit pension plans that cover certain employees located in the U.S., U.K., Canada, and various other statutorily required countries. We account for pension benefits using the accrual method. Benefits under these plans are based on employees' years of service and compensation during final years of service. All underlying plans are subject to periodic actuarial valuations by qualified actuarial firms using actuarial models to calculate the expense and liability for each plan. We use December 31 as the measurement date for our defined benefit pension plans. Under the Chubb Corp plans, prior to 2001, benefits were generally based on an employee’s years of service and average compensation during the last five years of employment. Effective January 1, 2001, the formula for providing pension benefits was changed from the final average pay formula to a cash balance formula. Under the cash balance formula, a notional account is established for each employee, which is credited semi-annually with an amount equal to a percentage of eligible compensation based on age and years of service plus interest based on the account balance. Chubb Corp employees hired prior to 2001 will generally be eligible to receive vested benefits based on the higher of the final average pay or cash balance formulas. Other postretirement benefit plans We also assumed Chubb Corp other postretirement benefit plans, principally healthcare and life insurance, to retired employees, their beneficiaries, and covered dependents. Healthcare coverage is contributory. Retiree contributions vary based upon retiree’s age, type of coverage, and years of service requirements. Life insurance coverage is non-contributory. Chubb funds a portion of the healthcare benefits obligation where such funding can be accomplished on a tax-effective basis. Benefits are paid as covered expenses are incurred. Amendments to U.S. Qualified and Excess Pension Plans and U.S. Retiree Healthcare Plan On October 31, 2016, we harmonized and amended several of our U.S. retirement programs to create a unified retirement savings program. In 2020, we will transition from a traditional defined benefit pension program that had been in effect for certain employees to a defined contribution program. Additionally, after 2025, we plan to eliminate a subsidized U.S. retiree healthcare and life insurance plan that had been in place for certain employees. Both amendments required a remeasurement of the plan assets and benefit obligations with updated assumptions, including discount rates and the expected return on assets. The plan amendments and related remeasurement of the obligation at October 31, 2016 resulted in a net decrease to the benefit obligations of $496 million as follows: • The amendment of the pension plan and excess pension plan resulted in a pre-tax curtailment gain of $113 million immediately recognized in income during the fourth quarter of 2016 as it reduced expected years of future service of active plan participants. • The amendment of the retiree healthcare plan resulted in a reduction in the obligation of $383 million , of which $410 million will be amortized as a reduction to expense over the next 4.5 years as it relates to benefits already accrued. During the fourth quarter of 2016 and for the year ended 2017, $ 15 million and $89 million , respectively, was amortized as a reduction to expense. Additionally, during 2017, the number of involuntary departures due to the Chubb integration met our established threshold for recognition in income. As a result, we recognized $39 million of accelerated amortization. At December 31, 2017, the remaining curtailment benefit balance was $267 million which will be amortized as a reduction to expense over the next 3.5 years. Obligations and funded status The funded status of the pension and other postretirement benefit plans as well as the amounts recognized in Accumulated other comprehensive income at December 31, 2017 and 2016 was as follows: Pension Benefits Other Postretirement Benefits 2017 2016 2017 2016 U.S. Plans Non-U.S. Plans U.S. Plans Non-U.S. Plans (in millions of U.S. dollars) Benefit obligation, beginning of year $ 3,035 $ 1,025 $ 10 $ 559 $ 165 $ 16 Acquisition of Chubb Corp — — 3,153 372 — 506 Service cost 63 17 75 18 2 10 Interest cost 105 27 103 30 4 17 Actuarial loss (gain) 232 (4 ) 131 204 (2 ) 36 Benefits paid (132 ) (28 ) (79 ) (22 ) (14 ) (11 ) Amendments — — — (9 ) (23 ) (410 ) Curtailments — (32 ) (259 ) (7 ) 2 — Settlements (18 ) (8 ) (99 ) (7 ) — — Foreign currency revaluation and other — 80 — (113 ) 3 1 Benefit obligation, end of year $ 3,285 $ 1,077 $ 3,035 $ 1,025 $ 137 $ 165 Plan assets at fair value, beginning of year $ 2,765 $ 962 $ 9 $ 564 $ 159 $ — Acquisition of Chubb Corp — — 2,473 315 — 138 Actual return on plan assets 441 100 359 168 6 29 Employer contributions 53 63 98 67 6 3 Benefits paid (132 ) (28 ) (79 ) (22 ) (14 ) (11 ) Settlements (18 ) (8 ) (95 ) (7 ) — — Foreign currency revaluation and other — 83 — (123 ) — — Plan assets at fair value, end of year $ 3,109 $ 1,172 $ 2,765 $ 962 $ 157 $ 159 Funded status at end of year $ (176 ) $ 95 $ (270 ) $ (63 ) $ 20 $ (6 ) Amounts recognized in Accumulated other comprehensive income, not yet recognized in net periodic cost (benefit): Net actuarial loss (gain) $ (227 ) $ 82 $ (207 ) $ 156 $ 12 $ 17 Prior service cost (benefit) — 6 — (2 ) (288 ) (395 ) Total $ (227 ) $ 88 $ (207 ) $ 154 $ (276 ) $ (378 ) The accumulated benefit obligation for the pension benefit plans was $ 4.3 billion and $ 3.8 billion at December 31, 2017 and 2016 , respectively. The accumulated benefit obligation is the present value of pension benefits earned as of the measurement date based on employee service and compensation prior to that date. It differs from the pension benefit obligation in the table above in that the accumulated benefit obligation includes no assumptions regarding future compensation levels. The net components of the funded status of the pension and other postretirement benefit plans are included in Accounts payable, accrued expenses, and other liabilities in the consolidated balance sheets. Chubb’s funding policy is to contribute amounts that meet regulatory requirements plus additional amounts determined based on actuarial valuations, market conditions and other factors. All benefit plans satisfy minimum funding requirements of the Employee Retirement Income Security Act of 1974 (ERISA). At December 31, 2017, we estimate that we will contribute $ 28 million to the pension plans and $2 million to the other postretirement benefits plan in 2018. The estimate is subject to change due to contribution decisions that are affected by various factors including our liquidity, market performance and management discretion. The weighted-average assumptions used to determine the projected benefit obligation were as follows: Pension Benefits U.S. Plans Non-U.S. Plans Other Postretirement Benefits December 31, 2017 Discount rate 3.59 % 2.76 % 2.77 % Rate of compensation increase 4.00 % 3.46 % N/A December 31, 2016 Discount rate 4.14 % 2.83 % 2.97 % Rate of compensation increase 4.00 % 3.57 % N/A The components of net pension and other postretirement benefit costs reflected in Net income and other changes in plan assets and benefit obligations recognized in other comprehensive income were as follows: Pension Benefits Other Postretirement Benefits U.S. Plans Non-U.S. Plans Year Ended December 31 2017 2016 2015 2017 2016 2015 2017 2016 2015 (in millions of U.S. dollars) Costs reflected in Net income: Service cost $ 63 $ 75 $ — $ 17 $ 18 $ 6 $ 2 $ 10 $ 1 Interest cost 105 103 — 27 30 21 4 17 — Expected return on plan assets (189 ) (165 ) — (42 ) (39 ) (29 ) (5 ) (8 ) — Amortization of net actuarial loss (gain) — — — 3 2 2 — (1 ) (1 ) Amortization of prior service cost — — — — (1 ) — (89 ) (15 ) — Curtailments — (117 ) — (27 ) — — (37 ) — — Settlements — (2 ) — — 1 1 — — — Net periodic (benefit) cost $ (21 ) $ (106 ) $ — $ (22 ) $ 11 $ 1 $ (125 ) $ 3 $ — Changes in plan assets and benefit obligations recognized in other comprehensive income Net actuarial loss (gain) $ (21 ) $ (326 ) $ — $ (57 ) $ 49 $ (16 ) $ (3 ) $ 17 $ — Prior service cost (benefit) — — — — (8 ) 1 (23 ) (395 ) — Amortization of net actuarial loss — — — (3 ) — — — — — Amortization of prior service cost — — — — — — 89 — — Curtailments — 117 — (6 ) — — 39 — — Settlements 1 2 — — (1 ) — — — — Total (increase) decrease in other comprehensive income $ (20 ) $ (207 ) $ — $ (66 ) $ 40 $ (15 ) $ 102 $ (378 ) $ — The estimated net actuarial loss that will be amortized from AOCI into net periodic benefit costs in Net income for Non-U.S. pension plans during 2018 is $1 million . The estimated net prior service credit that will be amortized from AOCI into net periodic benefit cost in Net income during 2018 for U.S. other postretirement benefit plans is $ 80 million . The weighted-average assumptions used to determine the net periodic pension and other postretirement benefit costs were as follows: Pension Benefits U.S. Plans Non-U.S. Plans Other Postretirement Benefits Year Ended December 31 2017 Discount rate in effect for determining service cost 4.20 % 3.55 % 2.84 % Discount rate in effect for determining interest cost 3.53 % 2.61 % 2.44 % Rate of compensation increase 4.00 % 3.57 % N/A Expected long-term rate of return on plan assets 7.00 % 4.23 % 3.00 % 2016 Discount rate in effect for determining service cost 4.38 % 3.85 % 4.32 % Discount rate in effect for determining interest cost 3.59 % 3.44 % 4.02 % Rate of compensation increase 4.00 % 3.33 % N/A Expected long-term rate of return on plan assets 7.00 % 4.79 % 6.34 % 2015 Discount rate NM 3.51 % NM Rate of compensation increase NM 3.09 % NM Expected long-term rate of return on plan assets NM 4.81 % NM NM – not meaningful The weighted-average healthcare cost trend rate assumptions used to measure the expected cost of healthcare benefits were as follows: U.S. Plans Non-U.S. Plans 2017 2016 2015 2017 2016 Healthcare cost trend rate 7.01 % 7.28 % 6.50 % 6.61 % 6.61 % Rate to which the cost trend rate is assumed to decline (the ultimate trend rate) 4.50 % 4.50 % 4.50 % 4.50 % 4.50 % Year that the rate reaches the ultimate trend rate 2038 2038 2026 2029 2029 The healthcare cost trend rate assumption has a significant effect on the amount of the accumulated other postretirement benefit obligation and the net other postretirement benefit cost reported. To illustrate, a one percent increase in the trend rate for each year would increase the accumulated other postretirement benefit obligation at December 31, 2017 by approximately $ 8 million and the aggregate of the service and interest cost components of net other postretirement benefit cost for the year ended December 31, 2017 by approximately $ 1 million . A one percent decrease in the trend rate for each year would decrease the accumulated other postretirement benefit obligation at December 31, 2017 by approximately $ 7 million and the aggregate of the service and interest cost components of net other postretirement benefit cost for the year ended December 31, 2017 by approximately $ 1 million . Plan Assets The long term objective of the pension plan is to provide sufficient funding to cover expected benefit obligations, while assuming a prudent level of portfolio risk. The assets of the pension plan are invested, either directly or through pooled funds, in a diversified portfolio of predominately equity securities and fixed maturities. We seek to obtain a rate of return that over time equals or exceeds the returns of the broad markets in which the plan assets are invested. The target allocation of plan assets is 55 percent to 65 percent invested in equity securities (including certain other investments measured using NAV), with the remainder primarily invested in fixed maturities. We rebalance our pension assets to the target allocation as market conditions permit. We determined the expected long term rate of return assumption for each asset class based on an analysis of the historical returns and the expectations for future returns. The expected long term rate of return for the portfolio is a weighted aggregation of the expected returns for each asset class. In order to minimize risk, the Plan maintains a listing of permissible and prohibited investments. In addition, the Plan has certain concentration limits and investment quality requirements imposed on permissible investments options. Investment risk is measured and monitored on an ongoing basis. The following table presents the fair values of the pension plan assets, by valuation hierarchy. For additional information on how we classify these assets within the valuation hierarchy, refer to Note 4 to the Consolidated financial statements.

We had other postretirement benefit plan assets of $157 million and $159 million at December 31, 2017 and 2016, respectively, all of which are held in equity securities and categorized as Level 1. Assets classified within Level 3 were nil and $5 million at December 31, 2017 and 2016, respectively, and the change in the balance during the years ended December 31, 2017 and 2016 was insignificant. Benefit payments were $200 million and $213 million for the years ended December 31, 2017 and 2016 , respectively. Expected future payments are as follows: Pension For the years ending December 31 U.S. Plans Non-U.S. Plans Other Postretirement Benefits (in millions of U.S. dollars) 2018 $ 129 $ 23 $ 17 2019 141 25 19 2020 148 29 20 2021 155 28 23 2022 163 27 25 2023-2027 881 159 44 Defined contribution plans (including 401(k)) Under these plans, employees' contributions may be supplemented by Chubb matching contributions based on the level of employee contribution. These contributions are invested at the election of each employee in one or more of several investment portfolios offered by a third-party investment advisor. Expenses for these plans totaled $166 million , $150 million , and $117 million for the years ended December 31, 2017 , 2016 , and 2015 , respectively. |

Segment Reporting [Abstract] | |
Segment information | Segment information Chubb operates through six business segments: North America Commercial P&C Insurance, North America Personal P&C Insurance, North America Agricultural Insurance, Overseas General Insurance, Global Reinsurance, and Life Insurance. These segments distribute their products through various forms of brokers, agencies, and direct marketing programs. All business segments have established relationships with reinsurance intermediaries. • The North America Commercial P&C Insurance segment includes the business written by Chubb divisions that provide property and casualty (P&C) insurance and services to large, middle market and small commercial businesses in the U.S., Canada, and Bermuda. This segment includes our retail divisions: Major Accounts, Commercial Insurance, including Small Commercial Insurance; and our wholesale and specialty divisions: Westchester and Chubb Bermuda. These divisions write a variety of coverages, including traditional commercial property, marine, general casualty, workers’ compensation, package policies, and risk management; specialty categories such as professional lines, marine, construction, environmental, medical, cyber risk, and excess casualty; as well as group accident and health (A&H) insurance. • The North America Personal P&C Insurance segment includes the business written by Chubb Personal Risk Services division, which comprises Chubb high net worth personal lines business and ACE Private Risk Services, with operations in the U.S. and Canada. This segment provides affluent and high net worth individuals and families with homeowners, automobile and collector cars, valuable articles (including fine arts), personal and excess liability, travel insurance, and recreational marine insurance and services. • The North America Agricultural Insurance segment includes the business written by Rain and Hail Insurance Service, Inc. which provides comprehensive multiple peril crop insurance (MPCI) and crop-hail insurance, and Chubb Agribusiness, which offers farm and ranch property as well as specialty P&C coverages, including commercial agriculture products. • The Overseas General Insurance segment includes the business written by two Chubb divisions that provide P&C insurance and services in the 51 countries and territories outside of North America where the company operates. Chubb International provides commercial P&C, A&H and traditional and specialty personal lines for large corporations, middle markets and small customers through retail brokers, agents and other channels locally around the world. Chubb Global Markets (CGM) provides commercial P&C excess and surplus lines and A&H through wholesale brokers in the London market and through Lloyd’s. These divisions write a variety of coverages, including traditional commercial P&C, specialty categories such as financial lines, marine, energy, aviation, political risk and construction risk, as well as group A&H and traditional and specialty personal lines. • The Global Reinsurance segment primarily includes the reinsurance business written by Chubb Tempest Re. Chubb Tempest Re provides a broad range of traditional and specialty reinsurance coverages to a diverse array of primary P&C companies. • The Life Insurance segment includes Chubb's international life operations written by Chubb Life, Chubb Tempest Life Re and the North American supplemental A&H and life business of Combined Insurance. Corporate primarily includes the results of all run-off asbestos and environmental (A&E) exposures, our run-off Brandywine business, and our Westchester specialty operations for 1996 and prior years, and certain other run-off exposures. In addition, Corporate includes the results of our non-insurance companies including Chubb Limited, Chubb Group Management and Holdings Ltd., and Chubb INA Holdings Inc. Our exposure to A&E claims principally arises out of liabilities acquired when we purchased Westchester Specialty in 1998, CIGNA’s P&C business in 1999, and the Chubb Corp run-off business in 2016. In addition, revenue and expenses managed at the corporate level, including realized gains and losses, interest expense, the non-operating income of our partially-owned entities, and income taxes are reported within Corporate. Chubb integration expenses and other merger-related expenses (both included in Chubb integration expenses in the Consolidated statements of operations), and the one-time benefit recorded in 2016 related to the harmonization of our U.S. pension plans, are also reported within Corporate. Chubb integration expenses are one-time costs that are directly attributable to the achievement of the annualized savings, including employee severance, third-party consulting fees, and systems integration expenses. Other merger-related expenses are one-time costs directly attributable to the merger, including rebranding, employee retention costs and other professional and legal fees related to the Chubb Corp acquisition. These items will not be allocated to the segment level as they are one-time in nature and are not related to the ongoing business activities of the segment. The Chief Executive Officer does not manage segment results or allocate resources to segments when considering these costs and they are therefore excluded from our definition of segment income. Therefore, segment income will only include underwriting income, net investment income, and other operating income and expense items such as each segment's share of the operating income (loss) related to partially-owned entities and miscellaneous income and expense items for which the segments are held accountable. Segment income also includes amortization of purchased intangibles related to business combination intangible assets acquired by the segment and other purchase accounting related intangible assets, including agency relationships, renewal rights, and client lists. The amortization of intangible assets purchased as part of the Chubb Corp acquisition is considered a Corporate cost as these are incurred by the overall company. We determined that this definition of segment income is appropriate and aligns with how the business is managed. As we progress through the integration and refine our processes as our business continues to evolve, we will evaluate and may further refine our segments and segment income measures. For segment reporting purposes, certain items are presented in a different manner below than in the consolidated financial statements. Management uses underwriting income as the main measures of segment performance. Chubb calculates underwriting income by subtracting Losses and loss expenses, Policy benefits, Policy acquisition costs, and Administrative expenses from Net premiums earned. To calculate segment income, include Net investment income, Other (income) expense, and Amortization of purchased intangibles. For the North America Agricultural Insurance segment, management includes gains and losses on crop derivatives as a component of underwriting income. For example, for the year ended December 31, 2017, underwriting income in our North America Agricultural Insurance segment was $ 392 million . This amount includes $ 7 million of realized losses related to crop derivatives which are reported in Net realized gains (losses) in the Corporate column below. For the Life Insurance segment, management includes Net investment income and (Gains) losses from fair value changes in separate account assets that do not qualify for separate account reporting under GAAP as components of Life Insurance underwriting income.

Related Party Transactions [Abstract] | |
Related party transactions | Related party transactions Starr Indemnity & Liability Company and its affiliates (collectively, Starr) We have a number of agency and reinsurance agreements with Starr, the Chairman of which is related to a member of our senior management team. A number of these agreements pre-dated our acquisition of Chubb Corp; however, in connection with our acquisition of Chubb Corp on January 14, 2016, we obtained Chubb Corp’s pre-existing business with Starr, which included agency agreements and agreements in which Chubb Corp was a reinsurer to Starr. Our Board has reviewed and approved our arrangements with Starr. We have agency, claims services and underwriting services agreements with various Starr subsidiaries. Under the agency agreements, we secure the ability to sell our insurance policies through Starr as one of our non-exclusive agents for writing policies, contracts, binders, or agreements of insurance or reinsurance. Under the claims services agreements, Starr adjusts the claims under policies and arranges for third party treaty and facultative agreements covering such policies. Under the underwriting services agreements, Starr underwrites insurance policies on our behalf and we agree to reinsure such policies to Starr under one or more quota reinsurance agreements. Transactions generated under these agreements were as follows: Year Ended December 31 (in millions of U.S. dollars) 2017 2016 2015 Gross premiums written $ 464 $ 658 $ 305 Ceded premiums written $ 175 $ 208 $ 78 Commissions paid $ 101 $ 145 $ 60 Commissions received $ 37 $ 56 $ 19 Losses and loss expenses incurred $ 438 $ 313 $ 137 Certain agency agreements also contain a profit-sharing arrangement based on loss ratios, triggered if Starr underwrites a minimum of $20 million of annual program business net written premiums on our behalf. No profit share commission has been payable yet under this arrangement. Another agency agreement contains a profit-sharing arrangement based on the earned premiums for the business underwritten by Starr (excluding workers’ compensation) and the reinsurance recoveries associated with excess of loss reinsurance agreements placed by Starr for the business underwritten. No profit share commission under this arrangement has been payable yet. Reinsurance recoverable on losses and loss expenses due from Starr was $557 million and $412 million as of December 31, 2017 and 2016, respectively, and the amount of ceded reinsurance premium payable included in Insurance and reinsurance balances payable in the consolidated balance sheet was $44 million and $72 million , respectively. ABR Re We own 11.3 percent of the common equity of ABR Reinsurance Capital Holdings Ltd. and warrants to acquire 0.5 percent of additional equity. ABR Reinsurance Capital Holdings Ltd., is the parent company of ABR Reinsurance Ltd. (ABR Re), an independent reinsurance company. Through long-term arrangements, Chubb will be the sole source of reinsurance risks ceded to ABR Re, and BlackRock, Inc. will be ABR Re’s exclusive investment management service provider. As an investor, Chubb is expected to benefit from underwriting profit generated by ABR Re’s reinsuring a wide range of Chubb’s primary insurance business and the income and capital appreciation BlackRock, Inc. seeks to deliver through its investment management services. In addition, Chubb has entered into an arrangement with BlackRock, Inc. under which both Chubb and BlackRock, Inc. will be entitled to an equal share of the aggregate amount of certain fees, including underwriting and investment management performance related fees, in connection with their respective reinsurance and investment management arrangements with ABR Re. ABR Re is a variable interest entity; however, Chubb is not the primary beneficiary and does not consolidate ABR Re because Chubb does not have the power to control and direct ABR Re’s most significant activities, including investing and underwriting. Our minority ownership interest is accounted for under the equity method of accounting. Chubb cedes premiums to ABR Re and recognizes the associated commissio ns. At December 31, 2017 and 2016, Chubb ceded reinsurance premiums of $ 342 million and $ 288 million , respectively, and recognized ceded commissions of $ 94 million and $ 66 million , respectively. At December 31, 2017 and 2016, the amount of Reinsurance recoverable on losses and loss expenses was $ 365 million and $ 148 million , respectively, and the amount of ceded reinsurance premium payable included in Insurance and reinsurance balances payable in our Consolidated balance sheets was $ 51 million and $ 53 million , respectively. |

Statutory Financial Information [Abstract] | |
Statutory financial information | Statutory financial information Our subsidiaries file financial statements prepared in accordance with statutory accounting practices prescribed or permitted by insurance regulators. Statutory accounting differs from GAAP in the reporting of certain reinsurance contracts, investments, subsidiaries, acquisition expenses, fixed assets, deferred income taxes, and certain other items. Some jurisdictions impose complex regulatory requirements on insurance companies while other jurisdictions impose fewer requirements. In some jurisdictions, we must obtain licenses issued by governmental authorities to conduct local insurance business. These licenses may be subject to reserves and minimum capital and solvency tests. Jurisdictions may impose fines, censure, and/or criminal sanctions for violation of regulatory requirements. The 2017 amounts below are based on estimates. Chubb's insurance and reinsurance subsidiaries are subject to insurance laws and regulations in the jurisdictions in which they operate. These regulations include restrictions that limit the amount of dividends or other distributions, such as loans or cash advances, available to shareholders without prior approval of the local insurance regulatory authorities. The amount of dividends available to be paid in 2018 without prior approval totals $5.8 billion . The statutory capital and surplus of our insurance subsidiaries met regulatory requirements for 2017 , 2016 , and 2015 . The minimum amounts of statutory capital and surplus necessary to satisfy regulatory requirements was $23.9 billion and $ 22.2 billion for December 31, 2017 and 2016 , respectively. These minimum regulatory capital requirements were significantly lower than the corresponding amounts required by the rating agencies which review Chubb’s insurance and reinsurance subsidiaries. The following tables present the combined statutory capital and surplus and statutory net income (loss) of our Property and casualty and Life subsidiaries: December 31 (in millions of U.S. dollars) 2017 2016 Statutory capital and surplus Property and casualty $ 40,498 $ 38,734 Life $ 1,507 $ 1,225 Year Ended December 31 (in millions of U.S. dollars) 2017 2016 2015 Statutory net income (loss) Property and casualty $ 8,123 $ 6,903 $ 2,712 Life $ 74 $ 55 $ (148 ) Several insurance subsidiaries follow accounting practices prescribed or permitted by the jurisdiction of domicile that differ from the applicable local statutory practice. The application of prescribed or permitted accounting practices does not have a material impact on Chubb's statutory surplus and income. As prescribed by the Restructuring discussed previously in Note 7 , certain of our U.S. subsidiaries discount certain A&E liabilities, which increased statutory capital and surplus by approximately $ 169 million and $155 million at December 31, 2017 and 2016 , respectively. Federal Insurance Company (Federal), a direct subsidiary of Chubb INA Holdings Inc., has a permitted practice granted by the Indiana Department of Insurance that relates to its investments in foreign subsidiaries and affiliates. Under Statement of Statutory Accounting Principles No. 97, Investments in Subsidiary, Controlled and Affiliated Entities, A Replacement of SSAP No. 88, in order for a reporting entity to admit its investments in foreign subsidiaries and affiliates, audited financial statements of the subsidiary or affiliate must be obtained to support the carrying value. Such financial statements must be prepared in accordance with U.S. GAAP, or alternatively, in accordance with the local statutory requirements in the subsidiary’s or affiliate’s country of domicile, with an audited footnote reconciliation of net income and shareholder’s equity as reported to a U.S. GAAP basis. With the explicit permission of the Indiana Department of Insurance, Federal obtains audited financial statements for its admitted foreign subsidiaries and affiliates, which had an aggregate carrying value of $ 156 million and $308 million at December 31, 2017 and 2016, respectively, prepared in accordance with their respective local statutory requirements and supplemented with a separate unaudited reconciliation of shareholder’s equity as reported to a U.S. GAAP basis. |

Basis of presentation | Basis of presentation Chubb Limited is a holding company incorporated in Zurich, Switzerland. Chubb Limited, through its subsidiaries, provides a broad range of insurance and reinsurance products to insureds worldwide. Our results are reported through the following business segments: North America Commercial P&C Insurance, North America Personal P&C Insurance, North America Agricultural Insurance, Overseas General Insurance, Global Reinsurance, and Life Insurance. Refer to Note 15 for additional information. The accompanying consolidated financial statements, which include the accounts of Chubb Limited and its subsidiaries (collectively, Chubb, 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, including internal reinsurance transactions, have been eliminated. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Amounts included in the Consolidated financial statements reflect our best estimates and assumptions; actual amounts could differ materially from these estimates. Chubb's principal estimates include: • unpaid loss and loss expense reserves, including long-tail asbestos and environmental (A&E) reserves; • future policy benefits reserves; • the valuation of value of business acquired (VOBA) and amortization of deferred policy acquisition costs and VOBA; • reinsurance recoverable, including a provision for uncollectible reinsurance; • the assessment of risk transfer for certain structured insurance and reinsurance contracts; • the valuation of the investment portfolio and assessment of OTTI; • the valuation of deferred tax assets; • the valuation of derivative instruments related to guaranteed living benefits (GLB); • the valuation and amortization of purchased intangibles; and • the assessment of goodwill for impairment. |
Premiums | Premiums Premiums are generally recorded as written upon inception of the policy. For multi-year policies for which premiums written are payable in annual installments, only the current annual premium is included as written at policy inception due to the ability of the insured/reinsured to commute or cancel coverage within the policy term. The remaining annual premiums are recorded as written at each successive anniversary date within the multi-year term. For P&C insurance and reinsurance products, premiums written are primarily earned on a pro-rata basis over the policy terms to which they relate. Unearned premiums represent the portion of premiums written applicable to the unexpired portion of the policies in force. For retrospectively-rated policies, written premiums are adjusted to reflect expected ultimate premiums consistent with changes to incurred losses, or other measures of exposure as stated in the policy, and earned over the policy coverage period. For retrospectively-rated multi-year policies, premiums recognized in the current period are computed using a with-and-without method as the difference between the ceding enterprise's total contract costs before and after the experience under the contract at the reporting date. Accordingly, for retrospectively-rated multi-year policies, additional premiums are generally written and earned when losses are incurred. Mandatory reinstatement premiums assessed on reinsurance policies are earned in the period of the loss event that gave rise to the reinstatement premiums. All remaining unearned premiums are recognized over the remaining coverage period. Premiums from long-duration contracts such as certain traditional term life, whole life, endowment, and long-duration personal accident and health (A&H) policies are generally recognized as revenue when due from policyholders. Traditional life policies include those contracts with fixed and guaranteed premiums and benefits. Benefits and expenses are matched with income to result in the recognition of profit over the life of the contracts. Retroactive loss portfolio transfer (LPT) contracts in which the insured loss events occurred prior to contract inception are evaluated to determine whether they meet criteria for reinsurance accounting. If reinsurance accounting is appropriate, written premiums are fully earned and corresponding losses and loss expenses recognized at contract inception. These contracts can cause significant variances in gross premiums written, net premiums written, net premiums earned, and net incurred losses in the years in which they are written. Reinsurance contracts sold not meeting criteria for reinsurance accounting are recorded using the deposit method as described below in Note 1 k). Reinsurance premiums assumed are based on information provided by ceding companies supplemented by our own estimates of premium when we have not received ceding company reports. Estimates are reviewed and adjustments are recorded in the period in which they are determined. Premiums are earned over the coverage terms of the related reinsurance contracts and range from one to three years. |
Deferred policy acquisition costs and value of business acquired | Deferred policy acquisition costs and value of business acquired Policy acquisition costs consist of commissions (direct and ceded), premium taxes, and certain underwriting costs related directly to the successful acquisition of new or renewal insurance contracts. A VOBA intangible asset is established upon the acquisition of blocks of long-duration contracts in a business combination and represents the present value of estimated net cash flows for the contracts in force at the acquisition date. Acquisition costs and VOBA, collectively policy acquisition costs, are deferred and amortized. Amortization is recorded in Policy acquisition costs in the Consolidated statements of operations. Policy acquisition costs on P&C contracts are generally amortized ratably over the period in which premiums are earned. Policy acquisition costs on traditional long-duration contracts are amortized over the estimated life of the contracts, generally in proportion to premium revenue recognized based upon the same assumptions used in estimating the liability for future policy benefits. For non-traditional long-duration contracts, we amortize policy acquisition costs over the expected life of the contracts in proportion to expected gross profits. The effect of changes in estimates of expected gross profits is reflected in the period the estimates are revised. Policy acquisition costs are reviewed to determine if they are recoverable from future income, including investment income. Unrecoverable policy acquisition costs are expensed in the period identified. Advertising costs are expensed as incurred except for direct-response campaigns that qualify for cost deferral, principally related to long-duration A&H business produced by the Overseas General Insurance segment, which are deferred and recognized as a component of Policy acquisition costs . For individual direct-response marketing campaigns that we can demonstrate have specifically resulted in incremental sales to customers and such sales have probable future economic benefits, incremental costs directly related to the marketing campaigns are capitalized as Deferred policy acquisition costs. Deferred policy acquisition costs, including deferred marketing costs, are reviewed regularly for recoverability from future income, including investment income, and amortized in proportion to premium revenue recognized, primarily over a ten -year period, the expected economic future benefit period based upon the same assumptions used in estimating the liability for future policy benefits. The expected future benefit period is evaluated periodically based on historical results and adjusted prospectively. The amount of deferred marketing costs reported in Deferred policy acquisition costs in the Consolidated balance sheets was $ 271 million and $ 256 million at December 31, 2017 and 2016 , respectively. Amortization expense for deferred marketing costs was $ 116 million, $ 92 million, and $ 78 million for the years ended December 31, 2017 , 2016 , and 2015 , respectively. |
Reinsurance | Reinsurance Chubb assumes and cedes reinsurance with other insurance companies to provide greater diversification of business and minimize the net loss potential arising from large risks. Ceded reinsurance contracts do not relieve Chubb of its primary obligation to policyholders. For both ceded and assumed reinsurance, risk transfer requirements must be met in order to account for a contract as reinsurance, principally resulting in the recognition of cash flows under the contract as premiums and losses. To meet risk transfer requirements, a reinsurance contract must include insurance risk, consisting of both underwriting and timing risk, and a reasonable possibility of a significant loss for the assuming entity. To assess risk transfer for certain contracts, Chubb generally develops expected discounted cash flow analyses at contract inception. Deposit accounting is used for contracts that do not meet risk transfer requirements. Deposit accounting requires that consideration received or paid be recorded in the balance sheet as opposed to recording premiums written or losses incurred in the statement of operations. Non-refundable fees on deposit contracts are earned based on the terms of the contract described below in Note 1 k). Reinsurance recoverable includes balances due from reinsurance companies for paid and unpaid losses and loss expenses and future policy benefits that will be recovered from reinsurers, based on contracts in force. The method for determining the reinsurance recoverable on unpaid losses and loss expenses incurred but not reported (IBNR) involves actuarial estimates consistent with those used to establish the associated liability for unpaid losses and loss expenses as well as a determination of Chubb's ability to cede unpaid losses and loss expenses under the terms of the reinsurance agreement. Reinsurance recoverable is presented net of a provision for uncollectible reinsurance determined based upon a review of the financial condition of reinsurers and other factors. The provision for uncollectible reinsurance is based on an estimate of the reinsurance recoverable balance that will ultimately be unrecoverable due to reinsurer insolvency, a contractual dispute, or any other reason. The valuation of this provision includes several judgments including certain aspects of the allocation of reinsurance recoverable on IBNR claims by reinsurer and a default analysis to estimate uncollectible reinsurance. The primary components of the default analysis are reinsurance recoverable balances by reinsurer, net of collateral, and default factors used to determine the portion of a reinsurer's balance deemed uncollectible. The definition of collateral for this purpose requires some judgment and is generally limited to assets held in a Chubb-only beneficiary trust, letters of credit, and liabilities held with the same legal entity for which Chubb believes there is a contractual right of offset. The determination of the default factor is principally based on the financial strength rating of the reinsurer. Default factors require considerable judgment and are determined using the current financial strength rating, or rating equivalent, of each reinsurer as well as other key considerations and assumptions. The more significant considerations include, but are not necessarily limited to, the following: • For reinsurers that maintain a financial strength rating from a major rating agency, and for which recoverable balances are considered representative of the larger population (i.e., default probabilities are consistent with similarly rated reinsurers and payment durations conform to averages), the financial rating is based on a published source and the default factor is based on published default statistics of a major rating agency applicable to the reinsurer's particular rating class. When a recoverable is expected to be paid in a brief period of time by a highly rated reinsurer, such as certain property catastrophe claims, a default factor may not be applied; • For balances recoverable from reinsurers that are both unrated by a major rating agency and for which management is unable to determine a credible rating equivalent based on a parent, affiliate, or peer company, we determine a rating equivalent based on an analysis of the reinsurer that considers an assessment of the creditworthiness of the particular entity, industry benchmarks, or other factors as considered appropriate. We then apply the applicable default factor for that rating class. For balances recoverable from unrated reinsurers for which the ceded reserve is below a certain threshold, we generally apply a default factor of 34 percent, consistent with published statistics of a major rating agency; • For balances recoverable from reinsurers that are either insolvent or under regulatory supervision, we establish a default factor and resulting provision for uncollectible reinsurance based on reinsurer-specific facts and circumstances. Upon initial notification of an insolvency, we generally recognize an expense for a substantial portion of all balances outstanding, net of collateral, through a combination of write-offs of recoverable balances and increases to the provision for uncollectible reinsurance. When regulatory action is taken on a reinsurer, we generally recognize a default factor by estimating an expected recovery on all balances outstanding, net of collateral. When sufficient credible information becomes available, we adjust the provision for uncollectible reinsurance by establishing a default factor pursuant to information received; and • For other recoverables, management determines the provision for uncollectible reinsurance based on the specific facts and circumstances. The methods used to determine the reinsurance recoverable balance and related provision for uncollectible reinsurance are regularly reviewed and updated, and any resulting adjustments are reflected in earnings in the period identified. Prepaid reinsurance premiums represent the portion of premiums ceded to reinsurers applicable to the unexpired coverage terms of the reinsurance contracts in-force. The value of reinsurance business assumed of $ 18 million and $ 20 million at December 31, 2017 and 2016 , respectively, included in Other assets in the accompanying Consolidated balance sheets, represents the excess of estimated ultimate value of the liabilities assumed under retroactive reinsurance contracts over consideration received. The value of reinsurance business assumed is amortized and recorded to Losses and loss expenses based on the payment pattern of the losses assumed and ranges between 9 and 40 years. The unamortized value is reviewed regularly to determine if it is recoverable based upon the terms of the contract, estimated losses and loss expenses, and anticipated investment income. Unrecoverable amounts are expensed in the period identified. |
Investments | Investments Fixed maturities are classified as either available for sale or held to maturity. The available for sale portfolio is reported at fair value. The held to maturity portfolio includes securities for which we have the ability and intent to hold to maturity or redemption and is reported at amortized cost. Equity securities are classified as available for sale and are recorded at fair value. Short-term investments comprise securities due to mature within one year of the date of purchase and are recorded at fair value which typically approximates cost. Short-term investments include certain cash and cash equivalents, which are part of investment portfolios under the management of external investment managers. Other investments principally comprise life insurance policies, policy loans, trading securities, other direct equity investments, investment funds, and limited partnerships. • Life insurance policies are carried at policy cash surrender value and income is recorded in Other income (expense). • Policy loans are carried at outstanding balance and interest income is recorded to Net investment income. • Trading securities are recorded on a trade date basis and carried at fair value. Unrealized gains and losses on trading securities are reflected in Other (income) expense. • Other investments over which Chubb can exercise significant influence are accounted for using the equity method and income is recorded in Other (income) expense. • All other investments over which Chubb cannot exercise significant influence are carried at fair value with changes in fair value recognized through OCI. For these investments, investment income is recognized in Net investment income and realized gains are recognized as related distributions are received. • Partially-owned investment companies comprise entities in which we hold an ownership interest in excess of three percent. These investments as well as Chubb's investments in investment funds where our ownership interest is in excess of three percent are accounted for under the equity method because Chubb exerts significant influence. These investments apply investment company accounting to determine operating results, and Chubb retains the investment company accounting in applying the equity method. This means that investment income, realized gains or losses, and unrealized gains or losses are included in the portion of equity earnings reflected in Other (income) expense. As a result of the timing of the receipt of valuation data from the investment managers, these investments are generally reported on a three month lag. Investments in partially-owned insurance companies primarily represent direct investments in which Chubb has significant influence and, as such, meet the requirements for equity accounting. We report our share of the net income or loss of the partially-owned insurance companies in Other (income) expense. Realized gains or losses on sales of investments are determined on a first-in, first-out basis. Unrealized appreciation (depreciation) on investments is included as a separate component of AOCI in Shareholders' equity. We regularly review our investments for OTTI. Refer to Note 3 for additional information. With respect to securities where the decline in value is determined to be temporary and the security's value is not written down, a subsequent decision may be made to sell that security and realize a loss. Subsequent decisions on security sales are the result of changing or unforeseen facts and circumstances (i.e., arising from a large insured loss such as a catastrophe), deterioration of the creditworthiness of the issuer or its industry, or changes in regulatory requirements. We believe that subsequent decisions to sell such securities are consistent with the classification of the majority of the portfolio as available for sale. We use derivative instruments including futures, options, swaps, and foreign currency forward contracts for the purpose of managing certain investment portfolio risks and exposures. Refer to Note 10 for additional information. Derivatives are reported at fair value and are recorded in the accompanying Consolidated balance sheets in either Accounts payable, accrued expenses, and other liabilities or Other assets with changes in fair value included in Net realized gains (losses) in the Consolidated statements of operations. Collateral held by brokers equal to a percentage of the total value of open futures contracts is included in the investment portfolio. Net investment income includes interest and dividend income and amortization of fixed maturity market premiums and discounts and is net of investment management and custody fees. In addition, net investment income includes the amortization of the fair value adjustment related to the acquired invested assets of Chubb Corp. An adjustment of $1,652 million related to the fair value of Chubb Corp’s fixed maturities securities was recorded (fair value adjustment) at the date of acquisition. At December 31, 2017, the remaining balance of this fair value adjustment was $858 million which is expected to amortize over the next four years; however, the estimate could vary materially based on current market conditions, bond calls, and the duration of the acquired investment portfolio. In addition, sales of these acquired fixed maturities would also reduce the fair value adjustment balance. For mortgage-backed securities, and any other holdings for which there is a prepayment risk, prepayment assumptions are evaluated and revised as necessary. Any adjustments required due to the resultant change in effective yields and maturities are recognized prospectively. Prepayment fees or call premiums that are only payable when a security is called prior to its maturity are earned when received and reflected in Net investment income. Chubb participates in a securities lending program operated by a third-party banking institution whereby certain assets are loaned to qualified borrowers and from which we earn an incremental return. Borrowers provide collateral, in the form of either cash or approved securities, of 102 percent of the fair value of the loaned securities. Each security loan is deemed to be an overnight transaction. Cash collateral is invested in a collateral pool which is managed by the banking institution. The collateral pool is subject to written investment guidelines with key objectives which include the safeguard of principal and adequate liquidity to meet anticipated redemptions. The fair value of the loaned securities is monitored on a daily basis, with additional collateral obtained or refunded as the fair value of the loaned securities changes. The collateral is held by the third-party banking institution, and the collateral can only be accessed in the event that the institution borrowing the securities is in default under the lending agreement. As a result of these restrictions, we consider our securities lending activities to be non-cash investing and financing activities. 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. The fair value of the securities on loan is included in fixed maturities and equity securities. The securities lending collateral is reported as a separate line in the Consolidated balance sheets with a related liability reflecting our obligation to return the collateral plus interest. Similar to securities lending arrangements, securities sold under repurchase agreements, whereby Chubb sells securities and repurchases them at a future date for a predetermined price, are accounted for as collateralized investments and borrowings and are recorded at the contractual repurchase amounts plus accrued interest. Assets to be repurchased are the same, or substantially the same, as the assets transferred and the transferor, through right of substitution, maintains the right and ability to redeem the collateral on short notice. The fair value of the underlying securities is included in fixed maturities and equity securities. In contrast to securities lending programs, the use of cash received is not restricted. We report the obligation to return the cash as Repurchase agreements in the Consolidated balance sheets. Refer to Note 4 for a discussion on the determination of fair value for Chubb's various investment securities. |
Cash | Cash Cash includes cash on hand and deposits with an original maturity of three months or less at time of purchase. Cash held by external money managers is included in Short-term investments. We have agreements with a third-party bank provider which implemented two international multi-currency notional cash pooling programs. In each program, participating Chubb entities establish deposit accounts in different currencies with the bank provider and each day the credit or debit balances in every account are notionally translated into a single currency (U.S. dollars) and then notionally pooled. The bank extends overdraft credit to any participating Chubb entity as needed, provided that the overall notionally-pooled balance of all accounts in each pool at the end of each day is at least zero. Actual cash balances are not physically converted and are not commingled between legal entities. Any overdraft balances incurred under this program by a Chubb entity would be guaranteed by Chubb Limited (up to $ 300 million in the aggregate). Our syndicated letter of credit facility allows for same day drawings to fund a net pool overdraft should participating Chubb entities overdraw contributed funds from the pool. |
Goodwill and other intangible assets | Goodwill and Other intangible assets Goodwill represents the excess of the cost of acquisitions over the fair value of net assets acquired and is not amortized. Goodwill is assigned at acquisition to the applicable reporting unit of the acquired entities giving rise to the goodwill. Goodwill impairment tests are performed annually or more frequently if circumstances indicate a possible impairment. For goodwill impairment testing, we use a qualitative assessment to determine whether it is more likely than not (i.e., more than a 50 percent probability) that the fair value of a reporting unit is greater than its carrying amount. If our assessment indicates less than a 50 percent probability that fair value exceeds carrying value, we quantitatively estimate a reporting unit's fair value. Goodwill recorded in connection with investments in partially-owned insurance companies is recorded in Investments in partially-owned insurance companies and is also measured for impairment annually. Indefinite lived intangible assets are not subject to amortization. Finite lived intangible assets are amortized over their useful lives, generally ranging from 1 to 30 years. Intangible assets are regularly reviewed for indicators of impairment. Impairment is recognized if the carrying amount is not recoverable from its undiscounted cash flows and is measured as the difference between the carrying amount and fair value. |
Unpaid losses and loss expenses | Unpaid losses and loss expenses A liability is established for the estimated unpaid losses and loss expenses under the terms of, and with respect to, Chubb's policies and agreements. Similar to premiums that are recognized as revenues over the coverage period of the policy, a liability for unpaid losses and loss expenses is recognized as expense when insured events occur over the coverage period of the policy. This liability includes a provision for both reported claims (case reserves) and incurred but not reported claims (IBNR reserves). IBNR reserve estimates are generally calculated by first projecting the ultimate cost of all losses that have occurred (expected losses), and then subtracting paid losses, case reserves, and loss expenses. The methods of determining such estimates and establishing the resulting liability are reviewed regularly and any adjustments are reflected in operations in the period in which they become known. Future developments may result in losses and loss expenses materially greater or less than recorded amounts. Except for net loss and loss expense reserves of $ 36 million net of discount, held at December 31, 2017 , representing certain structured settlements for which the timing and amount of future claim payments are reliably determinable and $ 41 million, net of discount, of certain reserves for unsettled claims that are discounted in statutory filings, Chubb does not discount its P&C loss reserves. This compares with reserves of $ 38 million for certain structured settlements and $ 50 million of certain reserves for unsettled claims at December 31, 2016 . Structured settlements represent contracts purchased from life insurance companies primarily to settle workers' compensation claims, where payments to the claimant by the life insurance company are expected to be made in the form of an annuity. Chubb retains the liability to the claimant in the event that the life insurance company fails to pay. At December 31, 2017 , the liability due to claimants was $ 586 million, net of discount, and reinsurance recoverables due from the life insurance companies was $ 550 million, net of discount. For structured settlement contracts where payments are guaranteed regardless of claimant life expectancy, the amounts recoverable from the life insurance companies at December 31, 2017 are included in Other assets in the Consolidated balance sheets, as they do not meet the requirements for reinsurance accounting. Included in Unpaid losses and loss expenses are liabilities for asbestos and environmental (A&E) claims and expenses. These unpaid losses and loss expenses are principally related to claims arising from remediation costs associated with hazardous waste sites and bodily-injury claims related to asbestos products and environmental hazards. The estimation of these liabilities is particularly sensitive to changes in the legal environment including specific settlements that may be used as precedents to settle future claims. However, Chubb does not anticipate future changes in laws and regulations in setting its A&E reserve levels. Also included in Unpaid losses and loss expenses is a fair value adjustment of $ 309 million at December 31, 2017 related to Chubb Corp’s historical unpaid losses and loss expenses. The estimated fair value consists of the present value of the expected net unpaid loss and loss adjustment expense payments adjusted for an estimated risk margin. The estimated cash flows are discounted at a risk free rate. The estimated risk margin varies based on the inherent risks associated with each type of reserve. The fair value is amortized through Amortization of purchased intangibles on the consolidated statements of operations over a range of 5 to 17 years, based on the estimated payout patterns of unpaid loss and loss expenses at the acquisition date. 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 premiums from previous accident years. For purposes of analysis and disclosure, management views prior period development to be changes in the nominal value of loss estimates from period to period, net of premium and profit commission adjustments on loss sensitive contracts. Prior period development generally excludes changes in loss estimates that do not arise from the emergence of claims, such as those related to uncollectible reinsurance, interest, unallocated loss adjustment expenses, or foreign currency. Accordingly, specific items excluded from prior period development include the following: gains/losses related to foreign currency remeasurement; losses recognized from the early termination or commutation of reinsurance agreements that principally relate to the time value of money; changes in the value of reinsurance business assumed reflected in losses incurred but principally related to the time value of money; and losses that arise from changes in estimates of earned premiums from prior accident years. Except for foreign currency remeasurement, which is included in Net realized gains (losses), these items are included in current year losses. |
Future policy benefits | Future policy benefits The valuation of long-duration contract reserves requires management to make estimates and assumptions regarding expenses, mortality, persistency, and investment yields. Estimates are primarily based on historical experience and information provided by ceding companies and include a margin for adverse deviation. Interest rates used in calculating reserves range from less than 1.0 percent to 8.0 percent at both December 31, 2017 and 2016 . Actual results could differ materially from these estimates. Management monitors actual experience and where circumstances warrant, will revise assumptions and the related reserve estimates. Revisions are recorded in the period they are determined. Certain of our long-duration contracts are supported by assets that do not qualify for separate account reporting under GAAP. These assets are classified as trading securities and reported in Other investments and the offsetting liabilities are reported in Future policy benefits in the Consolidated balance sheets. Changes in the fair value of separate account assets that do not qualify for separate account reporting under GAAP are reported in Other income (expense) and the offsetting movements in the liabilities are included in Policy benefits in the Consolidated statements of operations. |
Assumed reinsurance programs involving minimum benefit guarantees under annuity contracts | Assumed reinsurance programs involving minimum benefit guarantees under variable annuity contracts Chubb reinsures various death and living benefit guarantees associated with variable annuities issued primarily in the United States and Japan. We generally receive a monthly premium during the accumulation phase of the covered annuities (in-force) based on a percentage of either the underlying accumulated account values or the underlying accumulated guaranteed values. Depending on an annuitant's age, the accumulation phase can last many years. To limit our exposure under these programs, all reinsurance treaties include annual or aggregate claim limits and many include an aggregate deductible. The guarantees which are payable on death, referred to as guaranteed minimum death benefits (GMDB), principally cover shortfalls between accumulated account value at the time of an annuitant's death and either i) an annuitant's total deposits; ii) an annuitant's total deposits plus a minimum annual return; or iii) the highest accumulated account value attained at any policy anniversary date. In addition, a death benefit may be based on a formula specified in the variable annuity contract that uses a percentage of the growth of the underlying contract value. Liabilities for GMDBs are based on cumulative assessments or premiums to date multiplied by a benefit ratio that is determined by estimating the present value of benefit payments and related adjustment expenses divided by the present value of cumulative assessment or expected premiums during the contract period. Under reinsurance programs covering GLBs, we assume the risk of guaranteed minimum income benefits (GMIB) and guaranteed minimum accumulation benefits (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. Our GLB reinsurance products meet the definition of a derivative for accounting purposes and are carried at fair value with changes in fair value recognized in income. Refer to Notes 5 c ) and 10 a) for additional information. |
Deposit assets and liabilities | Deposit assets and liabilities Deposit assets arise from ceded reinsurance contracts purchased that do not transfer significant underwriting or timing risk. Deposit liabilities include reinsurance deposit liabilities and contract holder deposit funds. The reinsurance deposit liabilities arise from contracts sold for which there is not a significant transfer of risk. Contract holder deposit funds represent a liability for investment contracts sold that do not meet the definition of an insurance contract, and certain of these contracts are sold with a guaranteed rate of return. Under deposit accounting, consideration received or paid is recorded as a deposit asset or liability in the balance sheet as opposed to recording premiums and losses in the statement of operations. Interest income on deposit assets, representing the consideration received or to be received in excess of cash payments related to the deposit contract, is earned based on an effective yield calculation. The calculation of the effective yield is based on the amount and timing of actual cash flows at the balance sheet date and the estimated amount and timing of future cash flows. The effective yield is recalculated periodically to reflect revised estimates of cash flows. When a change in the actual or estimated cash flows occurs, the resulting change to the carrying amount of the deposit asset is reported as income or expense. Deposit assets of $ 89 million and $ 93 million at December 31, 2017 and 2016 , respectively, are reflected in Other assets in the Consolidated balance sheets and the accretion of deposit assets related to interest pursuant to the effective yield calculation is reflected in Net investment income in the Consolidated statements of operations. Deposit liabilities include reinsurance deposit liabilities of $ 100 million and $ 108 million and contract holder deposit funds of $ 1.8 billion and $ 1.5 billion at December 31, 2017 and 2016 , respectively. Deposit liabilities are reflected in Accounts payable, accrued expenses, and other liabilities in the Consolidated balance sheets. At contract inception, the deposit liability equals net cash received. An accretion rate is established based on actuarial estimates whereby the deposit liability is increased to the estimated amount payable over the contract term. The deposit accretion rate is the rate of return required to fund expected future payment obligations. We periodically reassess the estimated ultimate liability and related expected rate of return. Changes to the deposit liability are generally reflected through Interest expense to reflect the cumulative effect of the period the contract has been in force, and by an adjustment to the future accretion rate of the liability over the remaining estimated contract term. The liability for contract holder deposit funds equals accumulated policy account values, which consist of the deposit payments plus credited interest less withdrawals and amounts assessed through the end of the period. |
Property, Plant and Equipment, Policy [Policy Text Block] | Property and Equipment Property and equipment used in operations, including certain costs incurred to develop or obtain computer software for internal use, are capitalized and carried at cost less accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets. Property and equipment are included in Other assets in the Consolidated balance sheets and totaled $ 1.3 billion and $ 1.2 billion at December 31, 2017 and 2016, respectively. |
Foreign currency remeasurement and translation | Foreign currency remeasurement and translation The functional currency for each of our foreign operations is generally the currency of the local operating environment. Transactions in currencies other than a foreign operation's functional currency are remeasured into the functional currency and the resulting foreign exchange gains and losses are reflected in Net realized gains (losses) in the Consolidated statements of operations. Functional currency assets and liabilities are translated into the reporting currency, U.S. dollars, using period end exchange rates and the related translation adjustments are recorded as a separate component of AOCI. Functional statement of operations amounts expressed in functional currencies are translated using average exchange rates. |
Administrative expenses | Administrative expenses Administrative expenses generally include all operating costs other than policy acquisition costs. The North America Commercial P&C Insurance segment manages and uses an in-house third-party claims administrator, ESIS Inc. (ESIS). ESIS performs claims management and risk control services for domestic and international organizations that self-insure P&C exposures as well as internal P&C exposures. The net operating results of ESIS are included within Administrative expenses in the Consolidated statements of operations and were $ 38 million, $ 32 million, and $ 30 million for the years ended December 31, 2017 , 2016 , and 2015 , respectively. |
Income taxes | Income taxes Income taxes have been recorded related to those operations subject to income taxes. Deferred tax assets and liabilities result from temporary differences between the amounts recorded in the Consolidated financial statements and the tax basis of our assets and liabilities. The effect on deferred tax assets and liabilities of a change in tax law or rates is recognized in income in the period that includes the enactment date. For example, we recorded a net reduction in our deferred tax balances reflecting the impact of the Tax Cuts and Jobs Act (2017 Tax Act) in the fourth quarter of 2017, the period when the legislation was enacted. Refer to Note 8 for additional information. A valuation allowance against deferred tax assets is recorded if it is more likely than not that all, or some portion, of the benefits related to deferred tax assets will not be realized. The valuation allowance assessment considers tax planning strategies, where applicable. We recognize uncertain tax positions deemed more likely than not of being sustained upon examination. Recognized income tax positions are measured at the largest amount that has a greater than 50 percent likelihood of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. |
Earnings per share | Earnings per share Basic earnings per share is calculated using the weighted-average shares outstanding including participating securities with non-forfeitable rights to dividends such as unvested restricted stock. All potentially dilutive securities including stock options are excluded from the basic earnings per share calculation. In calculating diluted earnings per share, the weighted-average shares outstanding is increased to include all potentially dilutive securities. Basic and diluted earnings per share are calculated by dividing net income by the applicable weighted-average number of shares outstanding during the year. |
Cash flow information | Cash flow information Premiums received and losses paid associated with the GLB reinsurance products, which as discussed previously meet the definition of a derivative instrument for accounting purposes, are included within Cash flows from operating activities. Cash flows, such as settlements and collateral requirements, associated with GLB and all other derivative instruments are included on a net basis within Cash flows from investing activities. Purchases, sales, and maturities of short-term investments are recorded on a net basis within Cash flows from investing activities. |
Derivatives | Derivatives Chubb recognizes all derivatives at fair value in the Consolidated balance sheets and participates in derivative instruments in two principal ways: (i) To sell protection to customers as an insurance or reinsurance contract that meets the definition of a derivative for accounting purposes . For 2017 and 2016 , the reinsurance of GLBs was our primary product falling into this category; and (ii) To mitigate financial risks, principally arising from investment holdings, products sold, or assets and liabilities held in foreign currencies. For these instruments, changes in assets or liabilities measured at fair value are recorded as realized gains or losses in the Consolidated statements of operations. We did not designate any derivatives as accounting hedges during 2017 , 2016 , or 2015 . |
Share-based compensation | Share-based compensation Chubb measures and records compensation cost for all share-based payment awards at grant-date fair value. Compensation costs are recognized for share-based payment awards with only service conditions that have graded vesting schedules on a straight-line basis over the requisite service period for each separately vesting portion of the award as if the award were, in substance, multiple awards. Refer to Note 12 for additional information. |
Chubb integration expenses | Chubb integration expenses Direct costs related to the Chubb Corp acquisition were expensed as incurred. Chubb integration expenses were $ 310 million and $ 492 million for the years ended December 31, 2017 and 2016, respectively, and include all internal and external costs directly related to the integration activities of the Chubb Corp acquisition, consisting primarily of personnel-related expenses, including severance and employee retention and relocation; lease termination costs; and consulting fees. Chubb integration expenses were $ 33 million for the year ended December 31, 2015, consisting primarily of personnel-related expenses; consulting fees; and advisor fees. |
New accounting pronouncements | Adopted in 2017 Stock Compensation Effective January 2017, we prospectively adopted new guidance on stock compensation which requires recognition of the excess tax benefits or deficiencies of share-based compensation awards to employees through net income rather than through additional paid in capital. The calculation of the excess tax benefits or deficiencies is based on the difference between the market value of a stock award at the date of vesting, or at the time of exercise for a stock option, compared to the grant date fair value recognized as compensation expense in the Consolidated statements of operations. For the year ended December 31, 2017, the excess tax benefit recorded to Income tax expense in the Consolidated statement of operations was $ 48 million . Additionally, the guidance allowed for an election to account for forfeitures related to share-based payments either as they occur or through an estimation method. We elected to retain our current accounting for compensation expense using a forfeiture estimation process. Income Tax Accounting Implications of the Tax Cuts and Jobs Act The Tax Cuts and Jobs Act (2017 Tax Act) was signed into legislation in December 2017. Among other things, the 2017 Tax Act reduces the U.S. federal income tax rate to 21 percent from 35 percent effective in 2018, institutes a dividends received deduction for foreign earnings with a related tax for the deemed repatriation of unremitted foreign earnings and creates a new base erosion anti-abuse tax (BEAT) which is a new U.S. minimum tax. The Securities and Exchange Commission issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act, which provides guidance for the application of the 2017 Tax Act. The income tax guidance allows for the transition impact of the 2017 Tax Act to be recorded as 1) complete with all accounting implications identified, 2) provisional based on a reasonable estimate, or 3) not recorded as no reasonable estimate was determinable. We recorded a $450 million income tax transition benefit in the fourth quarter of 2017 on a provisional basis. This income tax benefit principally reflects our best estimate of the impact of the reduced U.S. corporate tax rate and other provisions of the 2017 Tax Act. Refer to Note 8 for additional information. Adopted in 2018 Revenue from Contracts with Customers In May 2014, the FASB issued an accounting standard that supersedes most existing revenue recognition guidance. The standard excludes from its scope the accounting for insurance contracts, leases, financial instruments, and certain other agreements that are governed under other GAAP guidance, but could affect the revenue recognition for certain of our claims management and risk control services. The updated guidance requires an entity to recognize revenue as performance obligations are met, in order to reflect the transfer of promised goods or services to customers in an amount that reflects the consideration the entity is entitled to receive for those goods or services. This guidance was effective for us on January 1, 2018. The adoption of this guidance did not have a material impact on our financial condition or results of operations given that the majority of our business is outside the scope of this guidance. Financial Instruments – Recognition and Measurement of Financial Assets and Financial Liabilities In January 2016, the FASB issued guidance that affects the recognition, measurement, presentation, and disclosure of financial instruments. The guidance requires equity investments to be measured at fair value with changes in fair value recognized through net income (other than those accounted for under equity method of accounting or those that result in consolidation of the investee). The standard was effective for us in the first quarter of 2018 and required recognition of a cumulative effect adjustment at adoption to beginning retained earnings. As a result, in the first quarter of 2018, we reduced other comprehensive income by $ 455 million , representing the unrealized appreciation on our equity investments, other than those accounted for under the equity method, with an offsetting increase in retained earnings. All subsequent changes in fair value will be recognized within realized gains (losses) on the consolidated statement of operations. Statement of Cash Flows In August 2016, the FASB issued guidance clarifying the classification of certain cash receipts and cash payments within the statement of cash flows, including distributions received from equity method investments. The guidance requires entities to make an accounting policy election to present cash flows received either in operating cash flows or investing cash flows based on cumulative equity-method earnings or on the nature of the distributions. We adopted this guidance effective January 1, 2018 and elected to retain our current presentation of cash receipts and cash payments based on the nature of the distributions. Goodwill Impairment In January 2017, the FASB issued updated guidance on goodwill impairment testing that eliminates Step 2 of the goodwill impairment test requiring entities to calculate the implied fair value of goodwill through a hypothetical purchase price allocation. Under the updated guidance, impairment will now be recognized as the amount by which a reporting unit’s carrying value exceeds its fair value. Although the standard would have been effective for us in the first quarter of 2020 on a prospective basis, we adopted this guidance early effective January 1, 2018, as permitted. The adoption of this guidance did not have an impact on our financial condition or results of operations. |
Accounting guidance not yet adopted | ccounting guidance not yet adopted Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income In February 2018, the FASB issued guidance that allows the reclassification from accumulated other comprehensive loss to retained earnings for stranded tax effects resulting from the newly enacted corporate tax rate. Because the adjustment of deferred taxes due to the reduction of the corporate tax rate is required to be included in net income, the tax effects of items within accumulated other comprehensive income (referred to as stranded tax effects) do not reflect the appropriate tax rates. The amount of the reclassification will be the difference between the 35 percent historical U.S. corporate tax rate and the newly enacted 21 percent U.S. corporate tax rate. This guidance is effective for us in the first quarter of 2019 with early adoption permitted. Premium Amortization on Purchased Callable Debt Securities In March 2017, the FASB issued guidance on the amortization period for purchased callable debt securities held at a premium. The guidance requires the premium to be amortized to the earliest call date. Under current guidance, premiums generally are amortized over the contracted life of the security. This guidance is effective for us in the first quarter of 2019 on a modified retrospective basis through a cumulative effect adjustment to beginning retained earnings. Early adoption is permitted. Securities held at a discount do not require an accounting change. Based on our best estimate at the time of this filing, the cumulative effect adjustment at the time of adoption would be approximately $ 30 million pre-tax. Lease Accounting In February 2016, the FASB issued accounting guidance requiring leases with lease terms of more than 12 months to recognize a right of use asset and a corresponding lease liability on the balance sheets. This accounting guidance is effective for us in the first quarter of 2019 on a modified retrospective basis with early adoption permitted. In January 2018, the FASB issued a proposed update that provides an alternative transition method of adoption, permitting the recognition of a cumulative-effect adjustment to retained earnings on the date of adoption. The adoption of the guidance is not expected to have a material impact on our financial condition or results of operations. We expect that the most significant impact will be the recognition of a right of use asset and a corresponding lease liability for our real estate leases. Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments In June 2016, the FASB issued guidance on the accounting for credit losses of financial instruments that are measured at amortized cost, including held to maturity securities and reinsurance recoverables, by applying an approach based on the current expected credit losses (CECL). The estimate of expected credit losses should consider historical information, current information, as well as reasonable and supportable forecasts, including estimates of prepayments. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset in order to present the net carrying value at the amount expected to be collected on the financial asset on the Consolidated balance sheet. The guidance also amends the current debt security other-than-temporary impairment model by requiring an estimate of the expected credit loss (ECL) only when the fair value is below the amortized cost of the asset. The length of time the fair value of an AFS debt security has been below the amortized cost will no longer impact the determination of whether a potential credit loss exists. The AFS debt security model will also require the use of a valuation allowance as compared to the current practice of writing down the asset. The standard is effective for us in the first quarter of 2020 with early adoption permitted in the first quarter of 2019. We will be able to assess the effect of adopting this guidance on our financial condition and results of operations closer to the date of adoption. |

Claims Development tables [Table Text Block] | This product line has a substantial geographic spread and a broad mix across industries. Types of coverage include risk management business predominantly with high deductible policies, loss sensitive business (i.e., retrospectively-rated policies), business fronted for captives, as well as excess and primary guaranteed cost coverages. The triangle below shows all loss and allocated expense development for the workers' compensation product line. In our prior period development disclosure, we exclude any loss development where there is a directly related premium adjustment. For workers' compensation, changes in the exposure base due to payroll audits will drive changes in ultimate losses.

The primary and excess liability business represents the largest part of these exposures. The former includes both monoline and commercial package liability. The latter includes a substantial proportion of commercial umbrella, excess and high excess business, where loss activity can produce significant volatility in the loss triangles at later ages within an accident year (and sometimes across years) due to the size of the limits afforded and the complex nature of the underlying losses. This line includes management and professional liability products provided to a wide variety of clients, from national accounts to small firms along with private and not-for-profit organizations, distributed through brokers, agents, wholesalers and MGAs. Many of these coverages, particularly D&O and E&O, are typically written on a claims-made form. While most of the coverages are underwritten on a primary basis, there are significant amounts of excess exposure with large policy limits.

Prior Period Development, by Segment [Table Text Block] | The following table summarizes (favorable) and adverse prior period development (PPD) by segment. Long-tail lines include lines such as workers' compensation, general liability, and professional liability; while short-tail lines include lines such as most property lines, energy, personal accident, and agriculture. In 2017, we determined that the loss development classification for certain businesses, previously grouped within the short-tail column in the table below, would be more appropriately grouped within the long-tail column to better align with the classification of these businesses within our loss development triangles. We also determined that the loss development for certain other businesses should be reclassified from long-tail to short-tail. We updated our 2016 and 2015 amounts below to conform to the current year presentation and reclassified $101 million and $46 million , respectively, of net favorable development into long-tail from short-tail. These changes to the previously disclosed amounts have no impact to our financial condition and results of operations.
