Business Combinations [Abstract] | |
Merger Agreement with ACE Limited | 2) Merger Agreement with ACE Limited On June 30, 2015, Chubb entered into an Agreement and Plan of Merger (Merger Agreement) with ACE Limited (ACE), a company organized under the laws of Switzerland, and William Investment Holdings Corporation (Merger Sub), a New Jersey corporation and a wholly owned indirect subsidiary of ACE, pursuant to which Merger Sub will merge with and into Chubb, with Chubb surviving as a wholly owned indirect subsidiary of ACE (the Merger). ACE has indicated that shortly after the completion of the Merger, it expects to merge Chubb with and into ACE INA Holdings Inc., a Delaware corporation and indirect subsidiary of ACE, with ACE INA Holdings Inc. continuing as the surviving corporation. At the effective time of the Merger, each share (except for certain shares held by ACE, Chubb or their subsidiaries) of common stock of Chubb, par value $1.00 per share, will be converted into the right to receive 0.6019 of a common share of ACE, par value CHF 24.15 per share, and $62.93 in cash. The Board of Directors of Chubb (the Board) unanimously approved the Merger Agreement and the transactions contemplated thereby, including the Merger. The closing of the Merger is subject to various customary conditions, including receipt of required insurance regulatory and other governmental approvals. Some other closing conditions have already been satisfied, including Chubb shareholder approval of the Merger Agreement, approval by ACE shareholders of certain Merger-related matters and the termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. The transaction is expected to close during the first quarter of 2016. The Merger Agreement contains certain termination rights for both Chubb and ACE and further provides that, upon termination under specified circumstances, Chubb would be required to pay to ACE a termination fee of $930 million. No such termination fee has been accrued as of September 30, 2015. Pursuant to the Merger Agreement, until the effective time of the Merger or termination of the Merger Agreement, the Corporation is required to conduct its business in the ordinary course in all material respects and, without the prior written consent of ACE, cannot take certain actions, except in each case as permitted pursuant to the Merger Agreement. |

Accounting Changes and Error Corrections [Abstract] | |
Accounting Pronouncements Not Yet Adopted | 3) Accounting Pronouncements Not Yet Adopted In February 2015, the Financial Accounting Standards Board issued updated guidance that amends certain aspects of the current consolidation accounting guidance. In particular, the new guidance modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities (VIEs) or voting interest entities and eliminates the presumption that a general partner should consolidate a limited partnership. The new guidance would be effective for the Corporation for the year beginning January 1, 2016. The Corporation is in the process of assessing the effect, if any, that the implementation of this guidance will have on its financial position and results of operations. |

Invested Assets | 4) Invested Assets (a) The amortized cost and fair value of fixed maturities and equity securities were as follows: September 30, 2015 Amortized Gross Gross Fair Value (in millions) Fixed maturities Tax exempt $ 18,890 $ 1,012 $ 29 $ 19,873 Taxable U.S. government and government agency and authority obligations 1,259 54 1 1,312 Corporate bonds 8,409 260 45 8,624 Foreign government and government agency obligations 5,858 269 5 6,122 Residential mortgage-backed securities 110 15 1 124 Commercial mortgage-backed securities 943 19 1 961 16,579 617 53 17,143 Total fixed maturities $ 35,469 $ 1,629 $ 82 $ 37,016 Equity securities $ 1,060 $ 742 $ 31 $ 1,771 December 31, 2014 Amortized Gross Gross Fair Value (in millions) Fixed maturities Tax exempt $ 18,614 $ 1,174 $ 16 $ 19,772 Taxable U.S. government and government agency and authority obligations 1,962 46 1 2,007 Corporate bonds 8,741 327 40 9,028 Foreign government and government agency obligations 6,380 295 3 6,672 Residential mortgage-backed securities 192 20 1 211 Commercial mortgage-backed securities 1,069 22 1 1,090 18,344 710 46 19,008 Total fixed maturities $ 36,958 $ 1,884 $ 62 $ 38,780 Equity securities $ 1,089 $ 894 $ 19 $ 1,964 The fair value and amortized cost of fixed maturities at September 30, 2015 by contractual maturity were as follows: Fair Value Amortized (in millions) Due in one year or less $ 2,193 $ 2,174 Due after one year through five years 11,621 11,173 Due after five years through ten years 13,722 13,032 Due after ten years 8,395 8,037 35,931 34,416 Residential mortgage-backed securities 124 110 Commercial mortgage-backed securities 961 943 $ 37,016 $ 35,469 Actual maturities could differ from contractual maturities because borrowers may have the right to call or prepay obligations. The Corporation’s equity securities comprise a diversified portfolio of primarily U.S. publicly-traded common stocks. The Corporation is involved in the normal course of business with VIEs primarily as a passive investor in residential mortgage-backed securities, commercial mortgage-backed securities and private equity limited partnerships issued by third party VIEs. The Corporation is not the primary beneficiary of these VIEs. The Corporation’s maximum exposure to loss with respect to these investments is limited to the investment carrying values included in the Corporation’s consolidated balance sheet and any unfunded partnership commitments. (b) The components of unrealized appreciation or depreciation, including unrealized other-than-temporary impairment losses, of investments carried at fair value were as follows: September 30 December 31 (in millions) Fixed maturities Gross unrealized appreciation $ 1,629 $ 1,884 Gross unrealized depreciation 82 62 1,547 1,822 Equity securities Gross unrealized appreciation 742 894 Gross unrealized depreciation 31 19 711 875 2,258 2,697 Deferred income tax liability 790 944 $ 1,468 $ 1,753 The following table summarizes, for all investment securities in an unrealized loss position at September 30, 2015, the aggregate fair value and gross unrealized depreciation, including unrealized other-than-temporary impairment losses, by investment category and length of time that individual securities have continuously been in an unrealized loss position. Less Than 12 Months 12 Months or More Total Fair Gross Fair Gross Fair Gross (in millions) Fixed maturities Tax exempt $ 1,287 $ 16 $ 249 $ 13 $ 1,536 $ 29 Taxable U.S. government and government agency and authority obligations 52 1 10 — 62 1 Corporate bonds 1,695 30 441 15 2,136 45 Foreign government and government agency obligations 430 3 125 2 555 5 Residential mortgage-backed securities — — 5 1 5 1 Commercial mortgage-backed securities 47 1 32 — 79 1 2,224 35 613 18 2,837 53 Total fixed maturities 3,511 51 862 31 4,373 82 Equity securities 138 27 8 4 146 31 $ 3,649 $ 78 $ 870 $ 35 $ 4,519 $ 113 At September 30, 2015, approximately 1,125 individual fixed maturities and 25 individual equity securities were in an unrealized loss position. The Corporation does not have the intent to sell and it is not more likely than not that the Corporation will be required to sell these fixed maturities before the securities recover to their amortized cost value. In addition, the Corporation believes that none of the declines in the fair values of these fixed maturities relate to credit losses. The Corporation has the intent and ability to hold the equity securities in an unrealized loss position for a period of time sufficient to allow for the recovery of cost. The Corporation believes that none of the declines in the fair value of these fixed maturities and equity securities were other than temporary at September 30, 2015. The following table summarizes, for all investment securities in an unrealized loss position at December 31, 2014, the aggregate fair value and gross unrealized depreciation, including unrealized other-than-temporary impairment losses, by investment category and length of time that individual securities have continuously been in an unrealized loss position.

Segment Reporting [Abstract] | |
Segments Information | 6) Segments Information The principal business of the Corporation is the sale of property and casualty insurance. The profitability of the property and casualty insurance business depends on the results of both underwriting operations and investments, which are viewed as two distinct operations. The underwriting operations are managed and evaluated separately from the investment function. The property and casualty insurance subsidiaries underwrite most lines of property and casualty insurance. Underwriting operations consist of four separate business units: personal insurance, commercial insurance, specialty insurance and reinsurance assumed. The personal segment targets the personal insurance market. The personal classes include automobile, homeowners and other personal coverages. The commercial segment includes those classes of business that are generally available in broad markets and are of a more commodity nature. Commercial classes include multiple peril, casualty, workers’ compensation and property and marine. The specialty segment includes those classes of business that are available in more limited markets since they require specialized underwriting and claim settlement. Specialty classes include professional liability coverages and surety.

Fair Value Disclosures [Abstract] | |
Fair Values of Financial Instruments | 7) Fair Values of Financial Instruments Fair values of financial instruments are determined by management using valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. Fair values are generally measured using quoted prices in active markets for identical assets or liabilities or other inputs, such as quoted prices for similar assets or liabilities, that are observable, either directly or indirectly. In those instances where observable inputs are not available, fair values are measured using unobservable inputs for the asset or liability. Unobservable inputs reflect the Corporation’s own assumptions about the assumptions that market participants would use in pricing the asset or liability and are developed based on the best information available in the circumstances. Fair value estimates derived from unobservable inputs are affected by the assumptions used, including the discount rates and the estimated amounts and timing of future cash flows. The derived fair value estimates cannot be substantiated by comparison to independent markets and are not necessarily indicative of the amounts that would be realized in a current market exchange. Certain financial instruments, particularly insurance contracts, are excluded from fair value disclosure requirements. The methods and assumptions used to estimate the fair values of financial instruments are as follows: (i) The carrying value of short term investments approximates fair value due to the short maturities of these investments. (ii) Fair values of fixed maturities are determined by management, utilizing prices obtained from a third party, nationally recognized pricing service or, in the case of securities for which prices are not provided by a pricing service, from third party brokers. For fixed maturities that have quoted prices in active markets, market quotations are provided. For fixed maturities that do not trade on a daily basis, the pricing service and brokers provide fair value estimates using a variety of inputs including, but not limited to, benchmark yields, reported trades, broker/dealer quotes, issuer spreads, bids, offers, reference data, prepayment rates and measures of volatility. Management reviews on an ongoing basis the reasonableness of the methodologies used by the relevant pricing service and brokers. In addition, management, using the prices received for the securities from the pricing service and brokers, determines the aggregate portfolio price performance and reviews it against applicable indices. If management believes that significant discrepancies exist, it will discuss these with the relevant pricing service or broker to resolve the discrepancies. (iii) Fair values of equity securities are determined by management, utilizing quoted market prices. (iv) Fair values of long term debt issued by Chubb are determined by management, utilizing prices obtained from a third party, nationally recognized pricing service. The carrying values and fair values of financial instruments were as follows: September 30, 2015 December 31, 2014 Carrying Fair Value Carrying Fair Value (in millions) Assets Invested assets Short term investments $ 3,052 $ 3,052 $ 1,318 $ 1,318 Fixed maturities 37,016 37,016 38,780 38,780 Equity securities 1,771 1,771 1,964 1,964 Liabilities Long term debt 3,300 3,788 3,300 4,013 At September 30, 2015 and December 31, 2014, a pricing service provided fair value amounts for approximately 99% of the Corporation’s fixed maturities. The prices obtained from a pricing service and brokers generally are non-binding, but are reflective of current market transactions in the applicable financial instruments. At September 30, 2015 and December 31, 2014, the Corporation held an insignificant amount of financial instruments in its investment portfolio for which a lack of market liquidity impacted the determination of fair value. The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels as follows: Level 1 – Unadjusted quoted prices in active markets for identical financial instruments. Level 2 – Other inputs that are observable for the financial instrument, either directly or indirectly. Level 3 – Significant unobservable inputs. The fair value of financial instruments categorized based upon the lowest level of input that was significant to the fair value measurement was as follows: September 30, 2015 Level 1 Level 2 Level 3 Total (in millions) Assets Short term investments $ 277 $ 2,775 $ — $ 3,052 Fixed maturities Tax exempt — 19,871 2 19,873 Taxable U.S. government and government agency and authority obligations — 1,312 — 1,312 Corporate bonds — 8,431 193 8,624 Foreign government and government agency obligations — 6,122 — 6,122 Residential mortgage-backed securities — 122 2 124 Commercial mortgage-backed securities — 961 — 961 — 16,948 195 17,143 Total fixed maturities — 36,819 197 37,016 Equity securities 1,765 — 6 1,771 $ 2,042 $ 39,594 $ 203 $ 41,839 Liabilities Long term debt $ — $ 3,788 $ — $ 3,788 December 31, 2014 Level 1 Level 2 Level 3 Total (in millions) Assets Short term investments $ 206 $ 1,112 $ — $ 1,318 Fixed maturities Tax exempt — 19,769 3 19,772 Taxable U.S. government and government agency and authority obligations — 2,007 — 2,007 Corporate bonds — 8,912 116 9,028 Foreign government and government agency obligations — 6,663 9 6,672 Residential mortgage-backed securities — 210 1 211 Commercial mortgage-backed securities — 1,090 — 1,090 — 18,882 126 19,008 Total fixed maturities — 38,651 129 38,780 Equity securities 1,958 — 6 1,964 $ 2,164 $ 39,763 $ 135 $ 42,062 Liabilities Long term debt $ — $ 4,013 $ — $ 4,013 |

Accounting Changes and Error Corrections [Abstract] | |
Accounting Pronouncements Not Yet Adopted | In February 2015, the Financial Accounting Standards Board issued updated guidance that amends certain aspects of the current consolidation accounting guidance. In particular, the new guidance modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities (VIEs) or voting interest entities and eliminates the presumption that a general partner should consolidate a limited partnership. The new guidance would be effective for the Corporation for the year beginning January 1, 2016. The Corporation is in the process of assessing the effect, if any, that the implementation of this guidance will have on its financial position and results of operations. |
