Basis of Presentation and Accounting Policies disclosure
Basis of Presentation and Accounting Policies disclosure [Text Block]	1. BASIS OF PRESENTATION AND ACCOUNTING POLICIES Basis of Presentation The interim consolidated financial statements include the accounts of The Travelers Companies, Inc. (together with its subsidiaries, the Company). These financial statements are prepared in conformity with U.S. generally accepted accounting principles (GAAP) and are unaudited. In the opinion of the Company’s management, all adjustments necessary for a fair presentation have been reflected. Certain financial information that is normally included in annual financial statements prepared in accordance with GAAP, but that is not required for interim reporting purposes, has been omitted. All material intercompany transactions and balances have been eliminated. The accompanying interim consolidated financial statements and related notes should be read in conjunction with the Company’s consolidated financial statements and related notes included in the Company’s 2013 Annual Report on Form 10-K. The preparation of the interim consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the interim consolidated financial statements and the reported amounts of revenues and claims and expenses during the reporting period. Actual results could differ from those estimates. On November 1, 2013, the Company acquired all of the issued and outstanding shares of The Dominion of Canada General Insurance Company (Dominion) for an aggregate purchase price of approximately $1.035 billion. Dominion primarily markets personal lines and small commercial insurance business in Canada. At the acquisition date, the Company recorded at fair value $3.91 billion of assets acquired and $2.88 billion of liabilities assumed as part of purchase accounting, including $16 million of identifiable intangible assets and $273 million of goodwill. The operating income and the amount of assets acquired from Dominion were included in the Company’s Financial, Professional & International Insurance segment effective at the acquisition date. Adoption of Accounting Standards Updates Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date In February 2013, the Financial Accounting Standards Board (FASB) issued updated guidance to resolve diversity in practice concerning the recognition, measurement, and disclosure of obligations resulting from certain joint and several liability arrangements for which the total amount under the arrangement is fixed at the reporting date. The guidance requires that the reporting entity measure joint and several liability arrangements as the amount the reporting entity agreed to pay on the basis of its arrangement among the co-obligors and any additional amount the reporting entity expects to pay on behalf of its co-obligors. The updated guidance was effective for the quarter ending March 31, 2014. The adoption of this guidance did not have any effect on the Company’s results of operations, financial position or liquidity. Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity In March 2013, the FASB issued updated guidance to resolve diversity in practice concerning the release of the cumulative foreign currency translation adjustment into net income when a parent sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets within a foreign entity. When a company ceases to have a controlling financial interest in a subsidiary within a foreign entity, the company should recognize any related cumulative translation adjustment into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary had resided. Upon the partial sale of an equity method investment that is a foreign entity, the company should release into earnings a pro rata portion of the cumulative translation adjustment. Upon the partial sale of an equity method investment that is not a foreign entity, the company should release into earnings the cumulative translation adjustment if the partial sale represents a complete or substantially complete liquidation of the foreign entity that holds the equity method investment. The updated guidance was effective for the quarter ending March 31, 2014. The adoption of this guidance did not have any effect on the Company’s results of operations, financial position or liquidity. Accounting Standards Not Yet Adopted Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity In April 2014, the FASB issued revised guidance to reduce diversity in practice for reporting discontinued operations. Under the previous guidance, any component of an entity that was a reportable segment, an operating segment, a reporting unit, a subsidiary, or an asset group was eligible for discontinued operations presentation. The revised guidance only allows disposals of components of an entity that represent a strategic shift (e.g., disposal of a major geographical area, a major line of business, a major equity method investment, or other major parts of an entity) and that have a major effect on a reporting entity’s operations and financial results to be reported as discontinued operations. The revised guidance also requires expanded disclosure in the financial statements for discontinued operations as well as for disposals of significant components of an entity that do not qualify for discontinued operations presentation. The updated guidance is effective for the quarter ending March 31, 2015. The adoption of this guidance is not expected to have a material effect on the Company’s results of operations, financial position or liquidity. Revenue from Contracts with Customers In May 2014, the FASB issued updated guidance to clarify the principles for recognizing revenue. While insurance contracts are not within the scope of this updated guidance, the Company’s fee income related to providing claims and policy management services as well as claim and loss prevention services will be subject to this updated guidance. 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. The following steps are applied in the updated guidance: (1) identify the contract(s) with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when, or as, the entity satisfies a performance obligation. The updated guidance is effective for the quarter ending March 31, 2017. The adoption of this guidance is not expected to have a material effect on the Company’s results of operations, financial position, or liquidity. Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period In June 2014, the FASB issued updated guidance to resolve diversity in practice concerning employee share-based payments that contain performance targets that could be achieved after the requisite service period. Many reporting entities account for performance targets that could be achieved after the requisite service period as performance conditions that affect the vesting of the award and, therefore, do not reflect the performance targets in the estimate of the grant-date fair value of the award. Other reporting entities treat those performance targets as nonvesting conditions that affect the grant-date fair value of the award. The updated guidance requires that a performance target that affects vesting and that can be achieved after the requisite service period be treated as a performance condition. As such, the performance target that affects vesting should not be reflected in estimating that fair value of the award at the grant date. Compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the periods for which service has been rendered. If the performance target becomes probable of being achieved before the end of the service period, the remaining unrecognized compensation cost for which requisite service has not yet been rendered is recognized prospectively over the remaining service period. The total amount of compensation cost recognized during and after the service period should reflect the number of awards that are expected to vest and should be adjusted to reflect those awards that ultimately vest. The updated guidance is effective for annual and interim periods beginning after December 15, 2015, with early adoption permitted. The adoption of this guidance is not expected to have a material effect on the Company’s results of operations, financial position or liquidity. Nature of Operations For the periods presented in these financial statements, the Company was organized into three reportable business segments: Business Insurance; Financial, Professional & International Insurance; and Personal Insurance. These segments reflected the manner in which the Company’s businesses were managed and represented an aggregation of products and services based on type of customer, how the business was marketed and the manner in which risks were underwritten. The specific business segments presented in these financial statements are as follows: Business Insurance The Business Insurance segment offers a broad array of property and casualty insurance and insurance-related services to its clients primarily in the United States. Business Insurance is organized into the following six groups, which collectively comprise Business Insurance Core operations: Select Accounts; Commercial Accounts; National Accounts; Industry-Focused Underwriting; Target Risk Underwriting; and Specialized Distribution. Business Insurance also includes the Special Liability Group (which manages the Company’s asbestos and environmental liabilities) and the assumed reinsurance and certain other runoff operations, which collectively are referred to as Business Insurance Other. Financial, Professional & International Insurance The Financial, Professional & International Insurance segment includes surety and financial liability coverages, which primarily use credit-based underwriting processes, as well as property and casualty products that are primarily marketed on a domestic basis in Canada, the United Kingdom and the Republic of Ireland, and on an international basis through Lloyd’s. The segment includes the Bond & Financial Products group as well as the International group. The International group includes Dominion, which the Company acquired in November 2013 and which writes personal lines and small commercial insurance business in Canada. In addition, the Company owns 49.5% of the common stock of J. Malucelli Participações em Seguros e Resseguros S.A. (JMalucelli), its joint venture in Brazil. JMalucelli primarily writes surety business in Brazil, as well as other property and casualty insurance business in Brazil. The Company’s investment in JMalucelli is accounted for using the equity method and is included in “other investments” on the consolidated balance sheet. Personal Insurance The Personal Insurance segment writes a broad range of property and casualty insurance covering individuals’ personal risks. The primary products of automobile and homeowners insurance are complemented by a broad suite of related coverages. On June 10, 2014, the Company announced a realignment of its management team that gave rise to a realignment of two of its three business segments, effective July 1, 2014. The Company’s International Insurance group, which had previously been included in the Financial, Professional & International Insurance segment, will be combined with the Company’s previous Business Insurance segment to create a new Business & International Insurance segment. The Bond & Financial Products group, which was the remaining business in the Financial, Professional & International Insurance segment, will now comprise the new Bond & Financial Products segment. The Personal Insurance segment will not be impacted by these changes. The changes were designed to reflect the realignment of the Company’s management team and the manner in which the Company’s businesses are managed effective July 1, 2014, and represent an aggregation of products and services based on type of customer, how the business is marketed and the manner in which risks are underwritten. The newly aligned segments will be presented in the Company’s financial statements beginning with the period ending September 30, 2014 and the prior periods presented will be restated to conform to the new presentation.

Adoption of Accounting Standards Updates

Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation Is Fixed at the Reporting Date

In February 2013, the Financial Accounting Standards Board (FASB) issued updated guidance to resolve diversity in practice concerning the recognition, measurement, and disclosure of obligations resulting from certain joint and several liability arrangements for which the total amount under the arrangement is fixed at the reporting date. The guidance requires that the reporting entity measure joint and several liability arrangements as the amount the reporting entity agreed to pay on the basis of its arrangement among the co-obligors and any additional amount the reporting entity expects to pay on behalf of its co-obligors. The updated guidance was effective for the quarter ending March 31, 2014. The adoption of this guidance did not have any effect on the Company’s results of operations, financial position or liquidity.

Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity

The adoption of this guidance did not have any effect on the Company’s results of operations, financial position or liquidity.

Accounting Standards Not Yet Adopted

Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity

In April 2014, the FASB issued revised guidance to reduce diversity in practice for reporting discontinued operations. Under the previous guidance, any component of an entity that was a reportable segment, an operating segment, a reporting unit, a subsidiary, or an asset group was eligible for discontinued operations presentation. The revised guidance only allows disposals of components of an entity that represent a strategic shift (e.g., disposal of a major geographical area, a major line of business, a major equity method investment, or other major parts of an entity) and that have a major effect on a reporting entity’s operations and financial results to be reported as discontinued operations. The revised guidance also requires expanded disclosure in the financial statements for discontinued operations as well as for disposals of significant components of an entity that do not qualify for discontinued operations presentation. The updated guidance is effective for the quarter ending March 31, 2015. The adoption of this guidance is not expected to have a material effect on the Company’s results of operations, financial position or liquidity.
