NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

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 Annual Report on Form 10-K for the year ended December 31, 2016 (the Company’s 2016 Annual Report) as updated by the Company’s Current Report on Form 8-K filed on June 20, 2017. The Form 8-K was filed to reclassify certain of the Company’s historical segment information to conform the presentation of such segment information to the manner in which the Company’s businesses have been managed beginning April 1, 2017 (as described in more detail below) and reflect the revised names and descriptions of certain businesses comprising these segments and other related changes.

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 March 13, 2017, the Company announced an agreement to acquire Simply Business, a leading digital provider of insurance policies to small businesses in the United Kingdom, for total consideration of approximately $490 million, which includes the repayment of debt and other obligations at the completion of the transaction.  The transaction is expected to close in the third quarter of 2017, subject to regulatory approvals and other customary closing conditions.  The Company will use a portion of the net proceeds from the issuance of senior notes in May 2017 (described in more detail in note 8) and internal resources to fund this transaction.

Adoption of Accounting Standards

Investments — Equity Method and Joint Ventures:  Simplifying the Transition to the Equity Method of Accounting

In March 2016, the Financial Accounting Standards Board (FASB) issued updated guidance that eliminates the requirement to retroactively apply the equity method of accounting when an investment that was previously accounted for using another method of accounting becomes qualified to apply the equity method due to an increase in the level of ownership interest or degree of influence.  If the investment was previously accounted for as an available-for-sale security, any related unrealized gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for the equity method is recognized through earnings.  The updated guidance was effective for reporting periods beginning after December 15, 2016, and was applied prospectively.  The adoption of this guidance did not have a material effect on the Company’s results of operations, financial position or liquidity.

Derivatives and Hedging:  Contingent Put and Call Options in Debt Instruments

In March 2016, the FASB issued updated guidance clarifying that when a call (put) option in a debt instrument can accelerate the repayment of principal on the debt instrument, a reporting entity does not need to assess whether the contingent event that triggers the ability to exercise the call (put) option is related to interest rates or credit risk in determining whether the option should be accounted for separately.  The updated guidance was effective for reporting periods beginning after December 15, 2016. The adoption of this guidance did not have a material effect on the Company’s results of operations, financial position or liquidity.

Compensation — Retirement Benefits: Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost

In March 2017, the FASB issued updated guidance to improve the presentation of net periodic pension cost and net periodic post retirement cost (net benefit costs). Net benefit costs comprise several components that reflect different aspects of an employer’s financial arrangements as well as the cost of benefits provided to employees.  The update requires that the employer service cost component be reported in the same lines as other employee compensation cost and that the other components (non-service costs) be presented separately from the service cost and outside of a subtotal of income from operations if one is presented.  The update also allows only the service cost component to be eligible for capitalization in assets when applicable.

The updated guidance is effective for reporting periods beginning after December 15, 2017. The update is to be applied retrospectively with respect to the presentation of service cost and non-service cost and prospectively with respect to applying the service cost only eligible for capitalization in assets guidance. Early adoption is permitted as of the first interim period of an annual period if an entity issues interim financial statements.

The Company adopted the updated guidance effective January 1, 2017. See note 12 which has been expanded to disclose the amount of service cost and non-service cost components of net periodic benefit cost and the line items in the consolidated statement of income in which such amounts are reported. The updated guidance with respect to only service costs being eligible for capitalization in assets was not applicable.

For information regarding accounting standards that the Company adopted during the years presented, see the “Adoption of Accounting Standards” section of note 1 of notes to the consolidated financial statements in the Company’s 2016 Annual Report as updated by the Company’s Current Report on Form 8-K filed on June 20, 2017.

Compensation — Stock Compensation: Scope of Modification Accounting

In May 2017, the FASB issued updated guidance related to a change to the terms or conditions (modification) of a share-based payment award.  The updated guidance provides that an entity should account for the effects of a modification unless the fair value and vesting conditions of the modified award and the classification of the modified award (equity or liability instrument) are the same as the original award immediately before the modification.

The updated guidance is effective for the quarter ending March 31, 2018.  The update is to be applied prospectively to an award modified on or after the adoption date. Early adoption is permitted in any interim periods for which financial statements have not yet been made available for issuance.

The Company adopted the updated guidance effective April 1, 2017. The adoption did not have an effect on the Company’s results of operations, financial position or liquidity.

Accounting Standards Not Yet Adopted

For information regarding accounting standards that the Company has not yet adopted, see the “Other Accounting Standards Not Yet Adopted” section of note 1 of notes to the consolidated financial statements in the Company’s 2016 Annual Report as updated by the Company’s Current Report on Form 8-K filed on June 20, 2017.

Nature of Operations

Effective April 1, 2017, the Company’s results are reported in the following three business segments — Business Insurance, Bond & Specialty Insurance and Personal Insurance, reflecting a change in the manner in which the Company’s businesses are managed as of that date, as well as the aggregation of products and services based on the type of customer, how the business is marketed and the manner in which risks are underwritten.  While the segmentation of the Company’s domestic businesses is unchanged, the Company’s international businesses, which were previously managed and reported in total within the Business and International Insurance segment, are now disaggregated by product type among the three newly aligned reportable business segments.  All prior periods presented have been reclassified to conform to this presentation.  In connection with these changes, the Company has revised the names and descriptions of certain businesses comprising the Company’s segments and has reflected other related changes.

Unrealized losses for all fixed maturities and equity securities reported at fair value for which fair value is less than 80% of amortized cost at June 30, 2017 totaled $1 million, representing less than 1% of the combined fixed maturity and equity security portfolios on a pre-tax basis and less than 1% of shareholders’ equity on an after-tax basis.

Impairment Charges

Impairment charges included in net realized investment gains in the consolidated statement of income were $5 million and $4 million for the three months ended June 30, 2017 and 2016, respectively, and $7 million and $22 million for the six months ended June 30, 2017 and 2016, respectively.

The cumulative amount of credit losses on fixed maturities held at June 30, 2017 and 2016, that were recognized in the consolidated statement of income from other-than-temporary impairments (OTTI) and for which a portion of the OTTI was recognized in other comprehensive income (loss) in the consolidated balance sheet was $83 million and $88 million, respectively.  These credit losses represent less than 1% of the fixed maturity portfolio on a pre-tax basis and less than 1% of shareholders’ equity on an after-tax basis at both dates.  There were no significant changes in the credit component of OTTI during the six months ended June 30, 2017 and 2016 from that disclosed in note 3 of notes to the consolidated financial statements in the Company’s 2016 Annual Report as updated by the Company’s Current Report on Form 8-K filed on June 20, 2017.

Derivative Financial Instruments

From time to time, the Company enters into U.S. Treasury note futures contracts to modify the effective duration of specific assets within the investment portfolio.  U.S. Treasury futures contracts require a daily mark-to-market and settlement with the broker.  At both June 30, 2017 and December 31, 2016, the Company had $400 million notional value of open U.S. Treasury futures contracts.  Net realized investment losses related to U.S. Treasury futures contracts for the three months and six months ended June 30, 2017 and 2016 were not significant.

4.     FAIR VALUE MEASUREMENTS

The Company’s estimates of fair value for financial assets and financial liabilities are based on the framework established in the fair value accounting guidance.  The framework is based on the inputs used in valuation, gives the highest priority to quoted prices in active markets and requires that observable inputs be used in the valuations when available.  The disclosure of fair value estimates in the fair value accounting guidance hierarchy is based on whether the significant inputs into the valuation are observable.  In determining the level of the hierarchy in which the estimate is disclosed, the highest priority is given to unadjusted quoted prices in active markets and the lowest priority to unobservable inputs that reflect the Company’s significant market assumptions.  The level in the fair value hierarchy within which the fair value measurement is reported is based on the lowest level input that is significant to the measurement in its entirety.  The three levels of the hierarchy are as follows:

·Level 1 - Unadjusted quoted market prices for identical assets or liabilities in active markets that the Company has the ability to access.

·Level 2 - Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in inactive markets; or valuations based on models where the significant inputs are observable (e.g., interest rates, yield curves, prepayment speeds, default rates, loss severities, etc.) or can be corroborated by observable market data.

·Level 3 - Valuations based on models where significant inputs are not observable.  The unobservable inputs reflect the Company’s own assumptions about the inputs that market participants would use.

Valuation of Investments Reported at Fair Value in Financial Statements

The Company utilized a pricing service to estimate fair value measurements for approximately 98% of its fixed maturities at both June 30, 2017 and December 31, 2016.

While the vast majority of the Company’s fixed maturities are included in Level 2, the Company holds a number of municipal bonds and corporate bonds which are not valued by the pricing service and estimates the fair value of these bonds using an internal pricing matrix with some unobservable inputs that are significant to the valuation.  Due to the limited amount of observable market information, the Company includes the fair value estimates for these particular bonds in Level 3.  The fair value of the fixed maturities for which the Company used an internal pricing matrix was $108 million and $99 million at June 30, 2017 and December 31, 2016, respectively.  Additionally, the Company holds a small amount of other fixed maturity investments that have characteristics that make them unsuitable for matrix pricing.  For these fixed maturities, the Company obtains a quote from a broker (primarily the market maker).  The fair value of the fixed maturities for which the Company received a broker quote was $97 million and $85 million at June 30, 2017 and December 31, 2016, respectively.  Due to the disclaimers on the quotes that indicate that the price is indicative only, the Company includes these fair value estimates in Level 3.

For more information regarding the valuation of the Company’s fixed maturities, equity securities and other investments, see note 4 of notes to the consolidated financial statements in the Company’s 2016 Annual Report as updated by the Company’s Current Report on Form 8-K filed on June 20, 2017.

Fair Value Hierarchy

The following tables present the level within the fair value hierarchy at which the Company’s financial assets and financial liabilities are measured on a recurring basis.  An investment transferred between levels during a period is transferred at its fair value as of the beginning of that period.

Other Intangible Assets

The following tables present a summary of the Company’s other intangible assets by major asset class:

(at June 30, 2017, in millions)	Gross Carrying Amount		Accumulated Amortization		Net
Subject to amortization (1)	$	210	$	163	$	47
Not subject to amortization	217		—		217

Not subject to amortization	217		—		217
Total	$	427	$	159	$	268

(1)   Intangible assets subject to amortization are comprised of fair value adjustments on claims and claim adjustment expense reserves, reinsurance recoverables and other contract and customer-related intangibles.  The time value of money and the risk adjustment (cost of capital) components of the intangible asset run off at different rates, and, as such, the amount recognized in income may be a net benefit in some periods and a net expense in other periods.

Amortization expense of intangible assets was $2 million for each of the three months ended June 30, 2017 and 2016, and $5 million for each of the six months ended June 30, 2017 and 2016.  Intangible asset amortization expense is estimated to be $4 million for the remainder of 2017, $8 million in 2018, $7 million in 2019, $5 million in 2020 and $5 million in 2021.

Gross claims and claim adjustment expense reserves at June 30, 2017 increased by $627 million from December 31, 2016, primarily reflecting the impacts of (i) higher volumes of insured exposures and loss cost trends for the current accident year and (ii) catastrophe losses incurred in the first six months of 2017, partially offset by the impacts of (iii) payments related to operations in runoff and (iv) net favorable prior year reserve development.

Reinsurance recoverables on unpaid losses at June 30, 2017 decreased by $104 million from December 31, 2016, primarily reflecting the impact of cash collections in the first six months of 2017, including the settlement of certain disputes as discussed in more detail in note 13.

Prior Year Reserve Development

The following disclosures regarding reserve development are on a “net of reinsurance” basis.

For the six months ended June 30, 2017 and 2016, estimated claims and claim adjustment expenses incurred included $214 million and $418 million, respectively, of net favorable development for claims arising in prior years, including $284 million and $468 million, respectively, of net favorable prior year reserve development impacting the Company’s results of operations and $25 million of accretion of discount in each period.

Net favorable prior year reserve development in the second quarter of 2017 totaled $125 million, primarily driven by better than expected loss experience in the segment’s domestic operations in (i) the workers’ compensation product line for multiple accident years, (ii) the commercial multi-peril product line for liability coverages for multiple accident years and (iii) the general liability product line for both primary and excess coverages for multiple accident years (excluding an increase to environmental reserves discussed below).  Net favorable prior year reserve development in the second quarter of 2016 totaled $125 million, primarily driven by better than expected loss experience in the segment’s domestic operations in (i) the workers’ compensation product line for accident years 2006 and prior as well as accident year 2015 and (ii) the general liability product line for both primary and excess coverages for accident years 2011 and 2015 (excluding an increase to environmental reserves discussed below), as well as in the segment’s international operations in Europe.  These factors contributing to net favorable prior year reserve development in the second quarters of 2017 and 2016 were partially offset by $65 million and $82 million increases, respectively, to environmental reserves.

Bond & Specialty Insurance.  Net favorable prior year reserve development in the second quarter and first six months of 2017 totaled $78 million and $92 million, respectively, primarily driven by better than expected loss experience in the segment’s domestic operations in the general liability product line for accident years 2012 through 2015.  Net favorable prior year reserve development in the second quarter of 2016 totaled $159 million, primarily driven by better than expected loss experience in the segment’s domestic operations in (i) the fidelity and surety product line for accident years 2010, 2013 and 2014 and (ii) the general liability product line for accident years 2007 through 2011.  Net favorable prior year reserve development in the first six months of 2016 totaled $225 million, primarily driven by better than expected loss experience in the segment’s domestic operations in (i) the fidelity and surety product line for accident years 2010 through 2014 and (ii) the general liability product line for accident years 2007 through 2011.

Personal Insurance.  Net favorable prior year reserve development in the second quarter and first six months of 2017 totaled $0 and $6 million, respectively.  Net favorable prior year reserve development in the second quarter and first six months of 2016 totaled $4 million and $44 million, respectively.

13.          CONTINGENCIES, COMMITMENTS AND GUARANTEES

Contingencies

The major pending legal proceedings, other than ordinary routine litigation incidental to the business, to which the Company or any of its subsidiaries is a party or to which any of the Company’s properties is subject are described below.

Asbestos and Environmental Claims and Litigation

In the ordinary course of its insurance business, the Company has received and continues to receive claims for insurance arising under policies issued by the Company asserting alleged injuries and damages from asbestos- and environmental-related exposures that are the subject of related coverage litigation. The Company is defending asbestos- and environmental-related litigation vigorously and believes that it has meritorious defenses; however, the outcomes of these disputes are uncertain.  In this regard, the Company employs dedicated specialists and aggressive resolution strategies to manage asbestos and environmental loss exposure, including settling litigation under appropriate circumstances.  Currently, it is not possible to predict legal outcomes and their impact on the future development of claims and litigation relating to asbestos and environmental claims. Any such development will be affected by future court decisions and interpretations, as well as

changes in applicable legislation. Because of these uncertainties, additional liabilities may arise for amounts in excess of the Company’s current insurance reserves. In addition, the Company’s estimate of ultimate claims and claim adjustment expenses may change. These additional liabilities or increases in estimates, or a range of either, cannot now be reasonably estimated and could result in income statement charges that could be material to the Company’s results of operations in future periods.

Other Proceedings Not Arising Under Insurance Contracts or Reinsurance Agreements

The Company is involved in other lawsuits, including lawsuits alleging extra-contractual damages relating to insurance contracts or reinsurance agreements, that do not arise under insurance contracts or reinsurance agreements.  The legal costs associated with such lawsuits are expensed in the period in which the costs are incurred.  Based upon currently available information, the Company does not believe it is reasonably possible that any such lawsuit or related lawsuits would be material to the Company’s results of operations or would have a material adverse effect on the Company’s financial position or liquidity.

Gain Contingency

On August 17, 2010, in a reinsurance dispute in New York state court captioned United States Fidelity & Guaranty Company v. American Re-Insurance Company, et al., the trial court granted summary judgment for United States Fidelity and Guaranty Company (USF&G), a subsidiary of the Company, and denied summary judgment for the reinsurers. The Court of Appeals largely affirmed the entry of summary judgment, but remanded two discrete issues for trial.

On November 7, 2016, the Company agreed to a settlement with one of the three defendants then remaining in this dispute. The Company received payment under the settlement in the fourth quarter of 2016 and, as a result, recognized a $126 million pre-tax ($82 million after-tax) gain in the fourth quarter, which was included in “other revenues” in the consolidated statement of income for the year ended December 31, 2016.  In connection with that settlement, the reinsurance recoverable balance related to this case was reduced from approximately $238 million to approximately $31 million in the Company’s consolidated balance sheet. At March 31, 2017, the claim related to the remaining defendants totaled $71 million, comprising the $31 million of reinsurance recoverable plus interest amounting to $40 million as of that date.  The interest was treated for accounting purposes as a gain contingency in accordance with FASB Topic 450, Contingencies, and accordingly was not recognized in the Company’s consolidated financial statements.

On May 1, 2017, the Company agreed to a settlement of this dispute with the two remaining defendants, along with the settlement of several other disputes with these same parties.  As a result of the settlement of all of these matters, the Company recorded an immaterial gain in “other revenues” in its consolidated statement of income for the three months ended June 30, 2017, and the reinsurance recoverable of $31 million in the Company’s balance sheet was fully satisfied.

Other Commitments and Guarantees

Commitments

Investment Commitments — The Company has unfunded commitments to private equity limited partnerships and real estate partnerships in which it invests.  These commitments totaled $1.58 billion and $1.60 billion at June 30, 2017 and December 31, 2016, respectively.

Guarantees

The maximum amount of the Company’s contingent obligation for indemnifications related to the sale of businesses that are quantifiable was $358 million at June 30, 2017, of which $2 million was recognized on the balance sheet at that date.

The maximum amount of the Company’s obligation for guarantees of certain investments and third-party loans related to certain investments that are quantifiable was $45 million at June 30, 2017, approximately $23 million of which is indemnified by a third party.  The maximum amount of the Company’s obligation related to the guarantee of certain insurance policy obligations of a former insurance subsidiary was $480 million at June 30, 2017, all of which is indemnified by a third party.  For more information regarding Company guarantees, see note 16 of notes to the consolidated financial statements in the Company’s 2016 Annual Report as updated by the Company’s Form 8-K filed on June 20, 2017.

Realignment of Reportable Business Segments

Effective April 1, 2017, the Company’s results are reported in the following three business segments — Business Insurance, Bond & Specialty Insurance and Personal Insurance, reflecting a change in the manner in which the Company’s businesses are managed as of that date, as well as the aggregation of products and services based on the type of customer, how the business is marketed and the manner in which risks are underwritten.  While the segmentation of the Company’s domestic businesses is unchanged, the Company’s international businesses, which were previously managed and reported in total within the Business and International Insurance segment, are now disaggregated by product type among the three newly aligned reportable business segments.  All prior periods presented have been reclassified to conform to this presentation.

In connection with these changes, the Company has revised the names and descriptions of certain businesses comprising the Company’s segments and has reflected other related changes.  The following discussion of segment results is based on the realigned reportable business segment structure effective April 1, 2017.

The following discussions of the Company’s net income and segment income are presented on an after-tax basis.  Discussions of the components of net income and segment income are presented on a pre-tax basis, unless otherwise noted.  Discussions of net income per common share are presented on a diluted basis.

Overview

Diluted net income per share of $2.11 in the second quarter of 2017 decreased by 6% from diluted net income per share of $2.24 in the same period of 2016.  Net income of $595 million in the second quarter of 2017 decreased by 10% from net income of $664 million in the same period of 2016.  The lower rate of decrease in diluted net income per share reflected the impact of share repurchases in recent periods.  The decrease in net income primarily reflected the pre-tax impacts of (i) lower net favorable prior year reserve development, (ii) higher catastrophe losses and (iii) lower underwriting margins excluding catastrophe losses and prior year reserve development (“underlying underwriting margins”), partially offset by (iv) higher net realized investment gains and (v) higher net investment income.  Catastrophe losses in the second quarters of 2017 and 2016 were $403 million and $333 million, respectively.  Net favorable prior year reserve development in the second quarters of 2017 and 2016 was $203 million and $288 million, respectively.  The lower underlying underwriting margins primarily resulted from (i) the timing of higher loss estimates in personal automobile bodily injury coverages that were consistent with the higher loss trends recognized in the last half of 2016 and (ii) normal quarterly variability in non-catastrophe weather-related losses.  Partially offsetting this net pre-tax decrease in income was a related decrease in income tax expense.

MANAGEMENT’S DISCUSSION AND ANALYSIS, Continued

Diluted net income per share of $4.28 in the first six months of 2017 decreased by 6% from diluted net income per share of $4.55 in the same period of 2016.  Net income of $1.21 billion in the first six months of 2017 decreased by 11% from net income of $1.36 billion in the same period of 2016.  The lower rate of decrease in diluted net income per share reflected the impact of share repurchases in recent periods.  The decrease in net income primarily reflected the pre-tax impacts of (i) lower net favorable prior year reserve development, (ii) lower underlying underwriting margins and (iii) higher catastrophe losses, partially offset by (iv) higher net investment income and (v) higher net realized investment gains.  Catastrophe losses in the first six months of 2017 and 2016 were $750 million and $651 million, respectively.  Net favorable prior year reserve development in the first six months of 2017 and 2016 was $284 million and $468 million, respectively.  The lower underlying underwriting margins primarily resulted from (i) the timing of higher loss estimates in personal automobile bodily injury coverages that were consistent with the higher loss trends recognized in the last half of 2016 and (ii) normal variability in non-catastrophe weather-related losses.  Partially offsetting this net pre-tax decrease in income was a related decrease in income tax expense.  Income tax expense in the first six months of 2017 was also reduced by $39 million as a result of the resolution of prior year tax matters in the first quarter of 2017.

The Company has insurance operations in Canada, the United Kingdom, the Republic of Ireland and throughout other parts of the world as a corporate member of Lloyd’s, as well as in Brazil and Colombia, primarily through joint ventures.  Because these operations are conducted in local currencies other than the U.S. dollar, the Company is subject to changes in foreign currency exchange rates.  For the three months and six months ended June 30, 2017 and 2016, changes in foreign currency exchange rates impacted reported line items in the statement of income by insignificant amounts.  The impact of these changes was not material to the Company’s net income or segment income for the periods reported.

Revenues

Earned Premiums

Earned premiums in the second quarter of 2017 were $6.35 billion, $284 million or 5% higher than in the same period of 2016.  Earned premiums in the first six months of 2017 were $12.53 billion, $486 million or 4% higher than in the same period of 2016.  In Business Insurance, earned premiums in the second quarter and first six months of 2017 increased by 2% and 1%, respectively, over the same periods of 2016.  In Bond & Specialty Insurance, earned premiums in the second quarter and first six months of 2017 increased by 3% and 2%, respectively, over the same periods of 2016.  In Personal Insurance, earned premiums in the second quarter and first six months of 2017 increased by 10% and 9%, respectively, over the same periods of 2016.  Factors contributing to the changes in earned premiums in each segment are discussed in more detail in the segment discussions that follow.

Net Investment Income

The following table sets forth information regarding the Company’s investments.

	Three Months Ended June 30,						Six Months Ended June 30,
(dollars in millions)	2017			2016			2017			2016
Average investments (1)	$	71,385		$	70,033		$	71,154		$	69,989
Pre-tax net investment income	598			549			1,208			1,093
After-tax net investment income	468			442			948			881
Average pre-tax yield (2)	3.4		%	3.1		%	3.4		%	3.1		%
Average after-tax yield (2)	2.6		%	2.5		%	2.7		%	2.5		%

(1)Excludes net unrealized investment gains and losses and reflects cash, receivables for investment sales, payables on investment purchases and accrued investment income.

(2)Excludes net realized and net unrealized investment gains and losses.

Net investment income in the second quarter of 2017 was $598 million, $49 million or 9% higher than in the same period of 2016.  Net investment income in the first six months of 2017 was $1.21 billion, $115 million or 11% higher than in the same period of 2016.  Net investment income from fixed maturity investments in the second quarter and first six months of 2017 was $471 million and $948 million, respectively, $26 million and $52 million lower, respectively, than in the same periods of 2016.  The decreases primarily resulted from lower long-term reinvestment rates available in the market, partially offset by

44

THE TRAVELERS COMPANIES, INC. AND SUBSIDIARIES

MANAGEMENT’S DISCUSSION AND ANALYSIS, Continued

the impact of a slightly higher level of fixed maturity investments.  Net investment income generated by non-fixed maturity investments in the second quarter and first six months of 2017 was $124 million and $255 million, respectively, $71 million and $158 million higher, respectively, than in the same periods of 2016, primarily due to higher returns from private equity limited partnerships.

Fee Income

The National Accounts market in Business Insurance is the primary source of the Company’s fee-based business.  The $3 million and $7 million decreases in fee income in the second quarter and first six months of 2017, respectively, compared with the same periods of 2016 are discussed in the Business Insurance segment discussion that follows.

Net Realized Investment Gains

The following table sets forth information regarding the Company’s net realized investment gains.

	Three Months Ended June 30,						Six Months Ended June 30,
(in millions)	2017			2016			2017			2016
Net Realized Investment Gains
Other-than-temporary impairment losses	$	(5	)	$	(4	)	$	(7	)	$	(22	)
Other net realized investment gains	85			23			92			32
Net realized investment gains	$	80		$	19		$	85		$	10

The increases in other net realized investment gains in the second quarter and first six months of 2017 compared with the same periods of 2016 were primarily driven by net realized gains on the sale of equity securities.

Other Revenues

Other revenues in all periods of 2017 and 2016 included installment premium charges.  Other revenues in the second quarter of 2017 also included a gain related to the settlement of a reinsurance dispute.  See “Gain Contingency” in note 13 of notes to the unaudited consolidated financial statements for further discussion.  Other revenues in the first six months of 2016 also included proceeds from the favorable settlement of a claims-related legal matter in the first quarter of 2016.

Claims and Expenses

Claims and Claim Adjustment Expenses

Claims and claim adjustment expenses in the second quarter of 2017 were $4.23 billion, $463 million or 12% higher than in the same period of 2016, primarily reflecting the impacts of (i) higher volumes of insured exposures, (ii) loss cost trends, (iii) lower net favorable prior year reserve development, (iv) higher catastrophe losses, (v) the timing of higher loss estimates in  personal automobile bodily injury liability coverages that were consistent with the higher loss trends recognized in the last half of 2016 and (vi) normal quarterly variability in non-catastrophe weather-related losses.  Catastrophe losses in the second quarter of 2017 primarily resulted from wind and hail storms in several regions of the United States.  Catastrophe losses in the second quarter of 2016 primarily resulted from wind and hail storms in several regions of the United States and wildfires in Canada.

Claims and claim adjustment expenses in the first six months of 2017 were $8.32 billion, $845 million or 11% higher than in the same period of 2016, primarily reflecting the impacts of (i) higher volumes of insured exposures, (ii) loss cost trends, (iii) lower net favorable prior year reserve development, (iv) higher catastrophe losses, (v) the timing of higher loss estimates in in personal automobile bodily injury liability coverages that were consistent with the higher loss trends recognized in the last half of 2016 and (vi) normal variability in non-catastrophe weather-related losses. Catastrophe losses in the first six months of 2017 and 2016 included the second quarter events described above, as well as wind and hail storms in several regions of the United States and a winter storm in the eastern United States in the first quarter of 2017, and wind and hail storms in Texas and several other regions of the United States and winter storms in the eastern United States in the first quarter of 2016.

Factors contributing to net favorable prior year reserve development during the second quarters and first six months of 2017 and 2016 are discussed in more detail in note 6 of notes to the unaudited consolidated financial statements.

Significant Catastrophe Losses

The following table presents the amount of losses recorded by the Company for significant catastrophes that occurred in the three months and six months ended June 30, 2017 and 2016, the amount of net unfavorable (favorable) prior year reserve development recognized in the three and six months ended June 30, 2017 and 2016 for significant catastrophes that occurred in 2016 and 2015, and the estimate of ultimate losses for those catastrophes at June 30, 2017 and December 31, 2016.  For purposes of the table, a significant catastrophe is an event for which the Company estimates its ultimate losses will be $100 million or more after reinsurance and before taxes.  For the Company’s definition of a catastrophe, refer to “Part II—Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations — Consolidated Overview” in the Company’s 2016 Annual Report as updated by the Company’s Current Report on Form 8-K filed on June 20, 2017.

Amortization of deferred acquisition costs in the second quarter of 2017 was $1.03 billion, $43 million or 4% higher than in the same period of 2016.  Amortization of deferred acquisition costs in the first six months of 2017 was $2.04 billion, $75 million or 4% higher than in the same period of 2016.  Amortization of deferred acquisition costs is discussed in more detail in the segment discussions that follow.

General and Administrative Expenses

General and administrative expenses in the second quarter and first six months of 2017 were $1.05 billion and $2.04 billion, respectively, compared to $1.05 billion and $2.05 billion, respectively, in the same periods of 2016.  General and administrative expenses are discussed in more detail in the segment discussions that follow.

Interest Expense

Interest expense in the second quarter and first six months of 2017 was $92 million and $181 million, respectively, compared with $93 million and $184 million, respectively, in the same periods of 2016.

Income Tax Expense

Income tax expense in the second quarter of 2017 was $195 million, $28 million or 13% lower than in the same period of 2016, primarily reflecting the impact of the $97 million decrease in income before income taxes in the second quarter of 2017.  Income tax expense in the first six months of 2017 was $338 million, $111 million or 25% lower than in the same period of 2016, primarily reflecting the impact of the $254 million decrease in income before income taxes in the first six months of 2017 and the $39 million reduction in income tax expense resulting from the resolution of prior year tax matters in the first quarter of 2017.

46

THE TRAVELERS COMPANIES, INC. AND SUBSIDIARIES

MANAGEMENT’S DISCUSSION AND ANALYSIS, Continued

The Company’s effective tax rate was 25% in the second quarters of both 2017 and 2016. The Company’s effective tax rate was 22% and 25% in the first six months of 2017 and 2016, respectively.  The effective tax rates in all periods were lower than the statutory rate of 35% primarily due to the impact of tax-exempt investment income on the calculation of the Company’s income tax provision.  In addition, the effective tax rate in the first six months of 2017 was reduced by the impact of the resolution of prior year tax matters discussed above.

Combined Ratio

The combined ratio of 96.7% in the second quarter of 2017 was 3.6 points higher than the combined ratio of 93.1% in the same period of 2016.  The combined ratio of 96.4% in the first six months of 2017 was 3.7 points higher than the combined ratio of 92.7% in the same period of 2016.

The loss and loss adjustment expense ratio of 65.6% in the second quarter of 2017 was 4.5 points higher than the loss and loss adjustment expense ratio of 61.1% in the same period of 2016.  Catastrophe losses accounted for 6.4 points and 5.5 points of the 2017 and 2016 second quarter loss and loss adjustment expense ratios, respectively.  Net favorable prior year reserve development in the second quarters of 2017 and 2016 provided 3.2 points and 4.7 points of benefit, respectively, to the loss and loss adjustment expense ratio.  The 2017 second quarter loss and loss adjustment expense ratio excluding prior year reserve development and catastrophe losses (“underlying loss and loss adjustment expense ratio”) was 2.1 points higher than the 2016 ratio on the same basis, primarily reflecting the impacts of (i) the timing of higher loss estimates in personal automobile bodily injury liability coverages that were consistent with the higher loss trends recognized in the last half of 2016 and (ii) normal quarterly variability in non-catastrophe weather-related losses.

The loss and loss adjustment expense ratio of 65.5% in the first six months of 2017 was 4.4 points higher than the loss and loss adjustment expense ratio of 61.1% in the same period of 2016.  Catastrophe losses accounted for 6.0 points and 5.4 points of the 2017 and 2016 six-month loss and loss adjustment expense ratios, respectively.  Net favorable prior year reserve development in the first six months of 2017 and 2016 provided 2.3 points and 3.9 points of benefit, respectively, to the loss and loss adjustment expense ratio.  The underlying loss and loss adjustment expense ratio in the first six months of 2017 was 2.2 points higher than the 2016 ratio on the same basis, primarily reflecting the impacts of (i) the timing of higher loss estimates in personal automobile bodily injury liability coverages that were consistent with the higher loss trends recognized in the last half of 2016 and (ii) normal variability in non-catastrophe weather-related losses.

The underwriting expense ratio of 31.1% for the second quarter of 2017 was 0.9 points lower than the underwriting expense ratio of 32.0% in the same period of 2016.  In the first six months of 2017, the underwriting expense ratio of 30.9% was 0.7 points lower than the underwriting expense ratio of 31.6% in the same period of 2016.

Overview

Segment income in the second quarter of 2017 was $429 million, $28 million or 7% higher than segment income of $401 million in the same period of 2016, primarily reflecting the pre-tax impacts of (i) higher net investment income and (ii) slightly higher underlying underwriting margins, partially offset by (iii) higher catastrophe losses.  Catastrophe losses in the second quarters of 2017 and 2016 were $184 million and $167 million, respectively.  Net favorable prior year reserve development in the second quarters of both 2017 and 2016 was $125 million.  Partially offsetting this net pre-tax increase in segment income was a related increase in income tax expense.

Segment income in the first six months of 2017 was $871 million, $23 million or 3% higher than segment income of $848 million in the same period of 2016, primarily reflecting the pre-tax impacts of (i) higher net investment income, partially offset by (ii) slightly lower underlying underwriting margins, (iii) lower other revenues and (iv) lower net favorable prior year reserve development.  Catastrophe losses in the first six months of 2017 and 2016 were $316 million and $315 million, respectively.  Net favorable prior year reserve development in the first six months of 2017 and 2016 was $186 million and $199 million, respectively. Partially offsetting this net pre-tax increase in segment income was a related increase in income tax expense.  Income tax expense in the first six months of 2017 was reduced by $15 million as a result of the resolution of prior year tax matters in the first quarter of 2017.

Revenues

Earned Premiums

Earned premiums in the second quarter of 2017 were $3.50 billion, $65 million or 2% higher than in the same period of 2016.  Earned premiums in the first six months of 2017 were $6.93 billion, $80 million or 1% higher than in the same period of 2016.

Net investment income in the second quarter of 2017 was $447 million, $43 million or 11% higher than in the same period of 2016.  Net investment income in the first six months of 2017 was $900 million, $97 million or 12% higher than in the same period of 2016.  Refer to the “Net Investment Income” section of the “Consolidated Results of Operations” discussion herein for a description of the factors contributing to the increases in the Company’s consolidated net investment income in the second quarter and first six months of 2017 compared with the same periods of 2016.  In addition, refer to note 2 of notes to the consolidated financial statements in the Company’s 2016 Annual Report as updated by the Company’s Current Report on Form 8-K filed on June 20, 2017 for a discussion of the Company’s net investment income allocation methodology.

Fee Income

National Accounts is the primary source of fee income.  Fee income in the second quarter of 2017 was $112 million, $3 million or 3% lower than in the same period of 2016.  Fee income in the first six months of 2017 was $221 million, $8 million or 3% lower than in the same period of 2016.  The decrease in both periods of 2017 primarily reflected lower serviced premium volume due to the depopulation of workers’ compensation residual market pools.

Other Revenues

Other revenues in all periods of 2017 and 2016 included installment premium charges.  Other revenues in the second quarter of 2017 also included a gain related to the settlement of a reinsurance dispute.  See “Gain Contingency” in note 13 of notes to the unaudited consolidated financial statements for further discussion.  Other revenues in the first six months of 2016 also included proceeds from the favorable settlement of a claims-related legal matter in the first quarter of 2016.

Claims and Expenses

Claims and Claim Adjustment Expenses

Claims and claim adjustment expenses in the second quarter of 2017 were $2.31 billion, $62 million or 3% higher than in the same period of 2016, primarily reflecting the impacts of (i) loss cost trends, (ii) higher volumes of insured exposures and (iii) higher catastrophe losses.

Claims and claim adjustment expenses in the first six months of 2017 were $4.57 billion, $114 million or 3% higher than in the same period of 2016, primarily reflecting the impacts of (i) loss cost trends, (ii) higher volumes of insured exposures and (iii) lower net favorable prior year reserve development.

Factors contributing to net favorable prior year reserve development during the second quarters and first six months of 2017 and 2016 are discussed in more detail in note 6 of notes to the unaudited consolidated financial statements.

Amortization of Deferred Acquisition Costs

Amortization of deferred acquisition costs in the second quarter of 2017 was $567 million, $14 million or 3% higher than in the same period of 2016.  Amortization of deferred acquisition costs in the first six months of 2017 was $1.12 billion, $22 million or 2% higher than in the same period of 2016.  The increases in both periods of 2017 were generally consistent with the increases in earned premiums.

General and Administrative Expenses

General and administrative expenses in the second quarter of 2017 were $636 million, $13 million or 2% lower than in the same period of 2016.  General and administrative expenses in the first six months of 2017 were $1.25 billion, $18 million or 1% lower than in the same period of 2016.

Income Tax Expense

Income tax expense in the second quarter of 2017 was $140 million, $21 million or 18% higher than in the same period of 2016, primarily reflecting the $49 million increase in income before income taxes.  Income tax expense in the first six months of 2017 was $269 million, $14 million or 5% higher than in the same period of 2016, primarily reflecting the $37 million increase in income before income taxes, partially offset by the impact of the $15 million reduction in income tax expense in the first quarter of 2017 resulting from the resolution of prior year tax matters.

Overview

Segment income in the second quarter of 2017 was $163 million, $52 million or 24% lower than segment income of $215 million in the same period of 2016, primarily reflecting the pre-tax impact of lower net favorable prior year reserve development.  Net favorable prior year reserve development in the second quarters of 2017 and 2016 was $78 million and $159 million, respectively.  Catastrophe losses in the second quarters of 2017 and 2016 were $1 million and $3 million, respectively.  Partially offsetting this net pre-tax decrease in segment income was a related decrease in income tax expense.

Segment income in the first six months of 2017 was $308 million, $67 million or 18% lower than segment income of $375 million in the same period of 2016, primarily reflecting the pre-tax impact of lower net favorable prior year reserve development.  Net favorable prior year reserve development in the first six months of 2017 and 2016 was $92 million and $225 million, respectively.  Catastrophe losses in the first six months of 2017 and 2016 were $2 million and $4 million, respectively.  Partially offsetting this net pre-tax decrease in segment income was a related decrease in income tax expense.  Income tax expense in the first six months of 2017 was also reduced by $17 million as a result of the resolution of prior year tax matters in the first quarter of 2017.

Revenues

Earned Premiums

Earned premiums in the second quarter of 2017 were $575 million, $16 million or 3% higher than in the same period of 2016. Earned premiums in the first six months of 2017 were $1.13 billion, $19 million or 2% higher than in the same period of 2016.

Net Investment Income

Net investment income in the second quarter of 2017 was $56 million, $2 million or 3% lower than in the same period of 2016.

Claims and Expenses

Claims and Claim Adjustment Expenses

Claims and claim adjustment expenses in the second quarter of 2017 were $174 million, $81 million or 87% higher than in the same period of 2016, primarily reflecting lower net favorable prior year reserve development.

Claims and claim adjustment expenses in the first six months of 2017 were $401 million, $129 million or 47% higher than in the same period of 2016, primarily reflecting lower net favorable prior year reserve development.

MANAGEMENT’S DISCUSSION AND ANALYSIS, Continued

Overview

Segment income in the second quarter of 2017 was $12 million, $83 million or 87% lower than segment income of $95 million in the same period of 2016, primarily reflecting the pre-tax impacts of (i) lower underlying underwriting margins and (ii) higher catastrophe losses, partially offset by (iii) higher net investment income.  Catastrophe losses in the second quarters of 2017 and 2016 were $218 million and $163 million, respectively.  There was no net prior year reserve development in the second quarter of 2017, compared with net favorable prior year reserve development of $4 million in the same period of 2016.  The lower underlying underwriting margins primarily resulted from the impacts of (i) normal quarterly variability in non-catastrophe weather-related losses and (ii) the timing of higher loss estimates in personal automobile bodily injury liability coverages that were consistent with the higher loss trends recognized in the last half of 2016.  Partially offsetting this net pre-tax decrease in segment income was a related decrease in income tax expense.

Segment income in the first six months of 2017 was $101 million, $146 million lower than segment income of $247 million in the same period of 2016, primarily reflecting the pre-tax impacts of (i) lower underlying underwriting margins, (ii) higher catastrophe losses and (iii) lower net favorable prior year reserve development, partially offset by (iv) higher net investment income.  Catastrophe losses in the first six months of 2017 and 2016 were $432 million and $332 million, respectively.  Net favorable prior year reserve development in the first six months of 2017 and 2016 was $6 million and $44 million, respectively.  The lower underlying underwriting margins primarily resulted from the impacts of (i) the timing of higher loss estimates in personal automobile bodily injury liability coverages that were consistent with the higher loss trends recognized in the last half of 2016 and (ii) normal variability in non-catastrophe weather-related losses.  Partially offsetting this net pre-tax decrease in segment income was a related decrease in income tax expense.  Income tax expense in the first six months of 2017 was also reduced by $7 million as a result of the resolution of prior year tax matters in the first quarter of 2017.

Revenues

Earned Premiums

Earned premiums in the second quarter of 2017 were $2.27 billion, $203 million or 10% higher than in the same period of 2016.  Earned premiums in the first six months of 2017 were $4.47 billion, $387 million or 9% higher than in the same period of 2016.  The increases in both periods primarily reflected the impact of increases in net written premiums over the preceding twelve months.

Net Investment Income

Net investment income in the second quarter of 2017 was $95 million, $8 million or 9% higher than in the same period of 2016.  Net investment income in the first six months of 2017 was $191 million, $19 million or 11% higher than in the same period of 2016.  Refer to the “Net Investment Income” section of the “Consolidated Results of Operations” discussion herein for a description of the factors contributing to the increases in the Company’s consolidated net investment income in the second quarter and first six months of 2017 compared with the same periods of 2016.  In addition, refer to note 2 of notes to the consolidated financial statements in the Company’s 2016 Annual Report as updated by the Company’s Current Report on Form 8-K filed on June 20, 2017 for a discussion of the Company’s net investment income allocation methodology.

Other Revenues

Other revenues in the second quarters and first six months of 2017 and 2016 primarily consisted of installment premium charges.

Claims and Expenses

Claims and Claim Adjustment Expenses

Claims and claim adjustment expenses in the second quarter of 2017 were $1.75 billion, $320 million or 22% higher than in the same period of 2016, primarily reflecting (i) higher volumes of insured exposures, (ii) higher catastrophe losses, (iii) normal quarterly variability in non-catastrophe weather-related losses, (iv) loss cost trends and (v) the timing of higher loss estimates in personal automobile bodily injury coverages that were consistent with the higher loss trends recognized in the last half of 2016.

MANAGEMENT’S DISCUSSION AND ANALYSIS, Continued

Claims and claim adjustment expenses in the first six months of 2017 were $3.35 billion, $602 million or 22% higher than in the same period of 2016, primarily reflecting (i) higher volumes of insured exposures, (ii) higher catastrophe losses, (iii) loss cost trends, (iv) the timing of higher loss estimates in personal automobile bodily injury coverages that were consistent with the higher loss trends recognized in the last half of 2016, (v) normal variability in non-catastrophe weather-related losses and (vi) lower net favorable prior year reserve development.

Factors contributing to net favorable prior year reserve development during the first six months of 2016 are discussed in more detail in note 6 of notes to the unaudited consolidated financial statements.

Amortization of Deferred Acquisition Costs

Amortization of deferred acquisition costs in the second quarter of 2017 was $357 million, $25 million or 8% higher than in the same period of 2016.  Amortization of deferred acquisition costs in the first six months of 2017 was $703 million, $48 million or 7% higher than in the same period of 2016.  The increases in both periods of 2017 were generally consistent with the increases in earned premiums.

The income tax benefit in the second quarter of 2017 was $(13) million, compared with income tax expense of $34 million in the same period of 2016, primarily reflecting the $130 million decrease in income before income taxes.  Income tax expense in the first six months of 2017 was $0, compared with income tax expense of $93 million in the same period of 2016, primarily reflecting the $239 million decrease in income before income taxes and the $7 million reduction in income tax expense resulting from the resolution of prior year income tax matters in the first quarter of 2017.  The level of income tax expense (benefit) in all periods reflected the impact of tax-exempt investment income on the calculation of the Company’s tax provision.

Combined Ratio

The combined ratio of 104.1% in the second quarter of 2017 was 6.3 points higher than the combined ratio of 97.8% in the same period of 2016.  The combined ratio of 101.9% in the first six months of 2017 was 6.1 points higher than the combined ratio of 95.8% in the same period of 2016.

The loss and loss adjustment expense ratio of 76.8% in the second quarter of 2017 was 7.9 points higher than the loss and loss adjustment expense ratio of 68.9% in the same period of 2016.  Catastrophe losses accounted for 9.6 points and 7.8 points of the loss and loss adjustment expense ratios in the second quarter of 2017 and 2016, respectively.  Net favorable prior year reserve development in the second quarters of 2017 and 2016 provided 0.0 points and 0.2 points of benefit, respectively, to the loss and loss adjustment expense ratio. The 2017 second quarter underlying loss and loss adjustment expense ratio was 5.9 points higher than the 2016 ratio on the same basis primarily reflecting the impacts of (i) normal quarterly variability in non-catastrophe weather-related losses, (ii) the timing of higher loss estimates in personal automobile bodily injury liability coverages that were consistent with the higher loss trends recognized in the last half of 2016 and (iii) the tenure impact of higher levels of new business in recent years in the Automobile product line.

The loss and loss adjustment expense ratio of 74.9% in the first six months of 2017 was 7.7 points higher than the loss and loss adjustment expense ratio of 67.2% in the same period of 2016.  Catastrophe losses accounted for 9.7 points and 8.2 points of the loss and loss adjustment expense ratios in the first six months of 2017 and 2016, respectively.  Net favorable prior year reserve development in the first six months of 2017 and 2016 provided 0.2 points and 1.1 points of benefit, respectively, to the loss and loss adjustment expense ratio.  The underlying loss and loss adjustment expense ratio in the first six months of 2017 was 5.3 points higher than the 2016 ratio on the same basis, primarily reflecting the impacts of (i) the timing of higher loss estimates in personal automobile bodily injury liability coverages that were consistent with the higher loss trends recognized in the last half of 2016, (ii) normal variability in non-catastrophe weather-related losses and (iii) the tenure impact of higher levels of new business in recent years in the Automobile product line.

The underwriting expense ratio of 27.3% for the second quarter of 2017 was 1.6 points lower than the underwriting expense ratio of 28.9% in the same period of 2016.  In the first six months of 2017, the underwriting expense ratio of 27.0% was 1.6 points lower than the underwriting expense ratio of 28.6% in the same period of 2016.  The declines in both periods of 2017 primarily reflected the impact of an increase in earned premiums.

ASBESTOS CLAIMS AND LITIGATION

The Company believes that the property and casualty insurance industry has suffered from court decisions and other trends that have expanded insurance coverage for asbestos claims far beyond the original intent of insurers and policyholders. The Company has received and continues to receive a significant number of asbestos claims from the Company’s policyholders (which includes others seeking coverage under a policy).  Factors underlying these claim filings include continued intensive advertising by lawyers seeking asbestos claimants and the continued focus by plaintiffs on defendants who were not traditionally primary targets of asbestos litigation.  The focus on these defendants is primarily the result of the number of traditional asbestos defendants who have sought bankruptcy protection in previous years.  In addition to contributing to the overall number of claims, bankruptcy proceedings may increase the volatility of asbestos-related losses by initially delaying the reporting of claims and later by significantly accelerating and increasing loss payments by insurers, including the Company. The bankruptcy of many traditional defendants has also caused increased settlement demands against those policyholders who are not in bankruptcy but remain in the tort system. Currently, in many jurisdictions, those who allege very serious injury and who can present credible medical evidence of their injuries are receiving priority trial settings in the courts, while those who have not shown any credible disease manifestation are having their hearing dates delayed or placed on an inactive docket.  Prioritizing claims involving credible evidence of injuries, along with the focus on defendants who were not traditionally primary targets of asbestos litigation, contributes to the claims and claim adjustment expense payment patterns experienced by the Company.  The Company’s asbestos-related claims and claim adjustment expense experience also has been impacted by the unavailability of other insurance sources potentially available to policyholders, whether through exhaustion of policy limits or through the insolvency of other participating insurers.

The Company continues to be involved in coverage litigation concerning a number of policyholders, some of whom have filed for bankruptcy, who in some instances have asserted that all or a portion of their asbestos-related claims are not subject to aggregate limits on coverage. In these instances, policyholders also may assert that each individual bodily injury claim should be treated as a separate occurrence under the policy. It is difficult to predict whether these policyholders will be successful on both issues. To the extent both issues are resolved in a policyholder’s favor and other Company defenses are not successful, the Company’s coverage obligations under the policies at issue would be materially increased and bounded only by the applicable per-occurrence limits and the number of asbestos bodily injury claims against the policyholders.  Although the Company has seen a reduction in the overall risk associated with these lawsuits, it remains difficult to predict the ultimate cost of these claims.

MANAGEMENT’S DISCUSSION AND ANALYSIS, Continued

Many coverage disputes with policyholders are only resolved through settlement agreements. Because many policyholders make exaggerated demands, it is difficult to predict the outcome of settlement negotiations. Settlements involving bankrupt policyholders may include extensive releases which are favorable to the Company but which could result in settlements for larger amounts than originally anticipated. There also may be instances where a court may not approve a proposed settlement, which may result in additional litigation and potentially less beneficial outcomes for the Company. As in the past, the Company will continue to pursue settlement opportunities.

In addition to claims against policyholders, proceedings have been launched directly against insurers, including the Company, by individuals challenging insurers’ conduct with respect to the handling of past asbestos claims and by individuals seeking damages arising from alleged asbestos-related bodily injuries.   It is possible that the filing of other direct actions against insurers, including the Company, could be made in the future.  It is difficult to predict the outcome of these proceedings, including whether the plaintiffs will be able to sustain these actions against insurers based on novel legal theories of liability. The Company believes it has meritorious defenses to these claims and has received favorable rulings in certain jurisdictions.

On January 29, 2009, the Company and PPG Industries, Inc. (PPG), along with approximately 30 other insurers of PPG, agreed in principle to settle asbestos-related coverage litigation under insurance policies issued to PPG (the “Agreement”). The Agreement was incorporated into the Modified Third Amended Plan of Reorganization (“Amended Plan”) proposed as part of the Pittsburgh Corning Corp. (PCC, which is 50% owned by PPG) bankruptcy proceeding. Pursuant to the Amended Plan, which was filed on January 30, 2009, PCC, along with enumerated other companies (including PPG as well as the Company as a participating insurer), receive protections afforded by Section 524(g) of the Bankruptcy Code from certain asbestos-related bodily injury claims.  Under the Agreement, the Company had the option to make a series of payments over 20 years totaling approximately $620 million to the Trust created under the Amended Plan, or it could elect to make a discounted payment.  On January 7, 2016, the remaining objections to the Amended Plan were dismissed. On April 27, 2016, the Amended Plan became effective and all the remaining conditions to the Agreement were satisfied.  The Company fully satisfied its obligation under the Agreement by making a discounted payment in the second quarter of 2016. The Company’s payments totaled $524 million, of which $518 million was related to asbestos reserves.  The Company’s obligations under the Agreement were included in its claims and claim adjustment expense reserves at March 31, 2016 and December 31, 2015.

The Company’s quarterly asbestos reserve reviews include an analysis of exposure and claim payment patterns by policyholder category, as well as recent settlements, policyholder bankruptcies, judicial rulings and legislative actions.  The Company also analyzes developing payment patterns among policyholders in the Home Office and Field Office, and Assumed Reinsurance and Other categories as well as projected reinsurance billings and recoveries.  In addition, the Company reviews its historical gross and net loss and expense paid experience, year-by-year, to assess any emerging trends, fluctuations, or characteristics suggested by the aggregate paid activity.  Conventional actuarial methods are not utilized to establish asbestos reserves nor have the Company’s evaluations resulted in any way of determining a meaningful average asbestos defense or indemnity payment.  Over the past decade, the property and casualty insurance industry, including the Company, has experienced net unfavorable prior year reserve development with regard to asbestos reserves, but the Company believes that over that period there has been a reduction in the volatility associated with the Company’s overall asbestos exposure as the overall asbestos environment has evolved from one dominated by exposure to significant litigation risks, particularly coverage disputes relating to policyholders in bankruptcy who were asserting that their claims were not subject to the aggregate limits contained in their policies, to an environment primarily driven by a frequency of litigation related to individuals with mesothelioma.  The Company’s overall view of the current underlying asbestos environment is essentially unchanged from recent periods and there remains a high degree of uncertainty with respect to future exposure to asbestos claims.

Because each policyholder presents different liability and coverage issues, the Company generally reviews the exposure presented by each policyholder at least annually.  Among the factors which the Company may consider in the course of this review are: available insurance coverage, including the role of any umbrella or excess insurance the Company has issued to the policyholder; limits and deductibles; an analysis of the policyholder’s potential liability; the jurisdictions involved; past and anticipated future claim activity and loss development on pending claims; past settlement values of similar claims; allocated claim adjustment expense; potential role of other insurance; the role, if any, of non-asbestos claims or potential non-asbestos claims in any resolution process; and applicable coverage defenses or determinations, if any, including the determination as to whether or not an asbestos claim is a products/completed operation claim subject to an aggregate limit and the available coverage, if any, for that claim.

Net asbestos paid loss and loss expenses in the first six months of 2017 were $139 million, compared with $575 million in the same period of 2016.  Net payments in the first six months of 2016 included the payment of the $518 million settlement amounts related to PPG as described above.  Net asbestos reserves were $1.19 billion at June 30, 2017, compared with $1.23 billion at June 30, 2016.

ENVIRONMENTAL CLAIMS AND LITIGATION

The Company has received and continues to receive claims from policyholders who allege that they are liable for injury or damage arising out of their alleged disposition of toxic substances. Mostly, these claims are due to various legislative as well as regulatory efforts aimed at environmental remediation. For instance, the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), enacted in 1980 and later modified, enables private parties as well as federal and state governments to take action with respect to releases and threatened releases of hazardous substances. This federal statute permits the recovery of response costs from some liable parties and may require liable parties to undertake their own remedial action. Liability under CERCLA may be joint and several with other responsible parties.

The Company has been, and continues to be, involved in litigation involving insurance coverage issues pertaining to environmental claims. The Company believes that some court decisions have interpreted the insurance coverage to be broader than the original intent of the insurers and policyholders. These decisions often pertain to insurance policies that were issued by the Company prior to the mid-1980s. These decisions continue to be inconsistent and vary from jurisdiction to jurisdiction. Environmental claims, when submitted, rarely indicate the monetary amount being sought by the claimant from the policyholder, and the Company does not keep track of the monetary amount being sought in those few claims which indicate a monetary amount.

THE TRAVELERS COMPANIES, INC. AND SUBSIDIARIES

MANAGEMENT’S DISCUSSION AND ANALYSIS, Continued

The resolution of environmental exposures by the Company generally occurs through settlements with policyholders as opposed to claimants.  Generally, the Company strives to extinguish any obligations it may have under any policy issued to the policyholder for past, present and future environmental liabilities and extinguish any pending coverage litigation dispute with the policyholder.  This form of settlement is commonly referred to as a “buy-back” of policies for future environmental liability. In addition, many of the agreements have also extinguished any insurance obligation which the Company may have for other claims, including but not limited to asbestos and other cumulative injury claims.  The Company and its policyholders may also agree to settlements which extinguish any liability arising from known specified sites or claims.  Where appropriate, these agreements also include indemnities and hold harmless provisions to protect the Company.  The Company’s general purpose in executing these agreements is to reduce the Company’s potential environmental exposure and eliminate the risks presented by coverage litigation with the policyholder and related costs.

In establishing environmental reserves, the Company evaluates the exposure presented by each policyholder and the anticipated cost of resolution, if any. In the course of this analysis, the Company generally considers the probable liability, available coverage and relevant judicial interpretations.  In addition, the Company considers the many variables presented, such as: the nature of the alleged activities of the policyholder at each site; the number of sites; the total number of potentially responsible parties at each site; the nature of the alleged environmental harm and the corresponding remedy at each site; the nature of government enforcement activities at each site; the ownership and general use of each site; the overall nature of the insurance relationship between the Company and the policyholder, including the role of any umbrella or excess insurance the Company has issued to the policyholder; the involvement of other insurers; the potential for other available coverage, including the number of years of coverage; the role, if any, of non-environmental claims or potential non-environmental claims in any resolution process; and the applicable law in each jurisdiction.  The evaluation of the exposure presented by a policyholder can change as information concerning that policyholder and the many variables presented is developed.  Conventional actuarial methods are not used to estimate these reserves.

In its review of environmental reserves, the Company considers: past settlement payments; changing judicial and legislative trends; its reserves for the costs of litigating environmental coverage matters; the potential for policyholders with smaller exposures to be named in new clean-up actions for both on- and off-site waste disposal activities; the potential for adverse development; the potential for additional new claims beyond previous expectations; and the potential higher costs for new settlements.

The duration of the Company’s investigation and review of these claims and the extent of time necessary to determine an appropriate estimate, if any, of the value of the claim to the Company vary significantly and are dependent upon a number of factors. These factors include, but are not limited to, the cooperation of the policyholder in providing claim information, the pace of underlying litigation or claim processes, the pace of coverage litigation between the policyholder and the Company and the willingness of the policyholder and the Company to negotiate, if appropriate, a resolution of any dispute pertaining to these claims. Because these factors vary from claim-to-claim and policyholder-by-policyholder, the Company cannot provide a meaningful average of the duration of an environmental claim. However, based upon the Company’s experience in resolving these claims, the duration may vary from months to several years.

The Company continues to receive notices from policyholders tendering claims for the first time, frequently under policies issued prior to the mid-1980s.  These policyholders continue to present smaller exposures, have fewer sites and are lower tier defendants.  Further, in many instances, clean-up costs have been reduced because regulatory agencies are willing to accept risk-based site analyses and more efficient clean-up technologies.  Over the past several years, the Company has experienced generally favorable trends in the number of new policyholders tendering environmental claims for the first time and in the number of pending declaratory judgment actions relating to environmental matters.  However, the degree to which those favorable trends have continued has been less than anticipated.  In addition, reserve development on existing environmental claims has been greater than anticipated, driven by claims and legal developments in a limited number of jurisdictions.  As a result of these factors, the Company increased its net environmental reserves by $65 million and $82 million in the second quarters of 2017 and 2016, respectively.

Net environmental paid loss and loss expenses in the first six months of 2017 were $37 million, compared with $23 million in the same period of 2016.  At June 30, 2017, approximately 94% of the net environmental reserve (approximately $385 million) was carried in a bulk reserve and included unresolved environmental claims, incurred but not reported environmental claims and the anticipated cost of coverage litigation disputes relating to these claims. The bulk reserve the Company carries is established and adjusted based upon the aggregate volume of in-process environmental claims and the Company’s

experience in resolving those claims. The balance, approximately 6% of the net environmental reserve (approximately $26 million), consists of case reserves.

UNCERTAINTY REGARDING ADEQUACY OF ASBESTOS AND ENVIRONMENTAL RESERVES

As a result of the processes and procedures discussed above, management believes that the reserves carried for asbestos and environmental claims are appropriately established based upon known facts, current law and management’s judgment. However, the uncertainties surrounding the final resolution of these claims continue, and it is difficult to determine the ultimate exposure for asbestos and environmental claims and related litigation. As a result, these reserves are subject to revision as new information becomes available and as claims develop. The continuing uncertainties include, without limitation, the risks and lack of predictability inherent in complex litigation, any impact from the bankruptcy protection sought by various asbestos producers and other asbestos defendants, a further increase or decrease in the cost to resolve, and/or the number of, asbestos and environmental claims beyond that which is anticipated, the emergence of a greater number of asbestos claims than anticipated as a result of extended life expectancies resulting from medical advances and lifestyle improvements, the role of any umbrella or excess policies the Company has issued, the resolution or adjudication of disputes pertaining to the amount of available coverage for asbestos and environmental claims in a manner inconsistent with the Company’s previous assessment of these claims, the number and outcome of direct actions against the Company, future developments pertaining to the Company’s ability to recover reinsurance for asbestos and environmental claims and the unavailability of other insurance sources potentially available to policyholders, whether through exhaustion of policy limits or through the insolvency of other participating insurers.  In addition, uncertainties arise from the insolvency or bankruptcy of policyholders and other defendants.  It is also not possible to predict changes in the legal, regulatory and legislative environment and their impact on the future development of asbestos and environmental claims.  This environment could be affected by changes in applicable legislation and future court and regulatory decisions and interpretations, including the outcome of legal challenges to legislative and/or judicial reforms establishing medical criteria for the pursuit of asbestos claims.  It is also difficult to predict the ultimate outcome of complex coverage disputes until settlement negotiations near completion and significant legal questions are resolved or, failing settlement, until the dispute is adjudicated. This is particularly the case with policyholders in bankruptcy where negotiations often involve a large number of claimants and other parties and require court approval to be effective. As part of its continuing analysis of asbestos and environmental reserves, the Company continues to study the implications of these and other developments.

62

THE TRAVELERS COMPANIES, INC. AND SUBSIDIARIES

MANAGEMENT’S DISCUSSION AND ANALYSIS, Continued

Because of the uncertainties set forth above, additional liabilities may arise for amounts in excess of the Company’s current insurance reserves.  In addition, the Company’s estimate of claims and claim adjustment expenses may change.  These additional liabilities or increases in estimates, or a range of either, cannot now be reasonably estimated and could result in income statement charges that could be material to the Company’s operating results in future periods.

INVESTMENT PORTFOLIO

The Company’s invested assets at June 30, 2017 were $72.33 billion, of which 93% was invested in fixed maturity and short-term investments, 1% in equity securities, 1% in real estate investments and 5% in other investments.  Because the primary purpose of the investment portfolio is to fund future claims payments, the Company employs a conservative investment philosophy.  A significant majority of funds available for investment are deployed in a widely diversified portfolio of high quality, liquid, taxable U.S. government, tax-exempt U.S. municipal and taxable corporate and U.S. agency mortgage-backed bonds.

The carrying value of the Company’s fixed maturity portfolio at June 30, 2017 was $61.91 billion.  The Company closely monitors the duration of its fixed maturity investments, and investment purchases and sales are executed with the objective of having adequate funds available to satisfy the Company’s insurance and debt obligations.  The weighted average credit quality of the Company’s fixed maturity portfolio, both including and excluding U.S. Treasury securities, was “Aa2” at both June 30, 2017 and December 31, 2016.  Below investment grade securities represented 2.7% and 2.9% of the total fixed maturity investment portfolio at June 30, 2017 and December 31, 2016, respectively.  The average effective duration of fixed maturities and short-term securities was 4.2 (4.6 excluding short-term securities) at June 30, 2017 and 4.2 (4.5 excluding short-term securities) at December 31, 2016.

Obligations of States, Municipalities and Political Subdivisions

The Company’s fixed maturity investment portfolio at June 30, 2017 and December 31, 2016 included $32.11 billion and $31.91 billion, respectively, of securities which are obligations of states, municipalities and political subdivisions (collectively referred to as the municipal bond portfolio).  The municipal bond portfolio is diversified across the United States, the District of Columbia and Puerto Rico and includes general obligation and revenue bonds issued by states, cities, counties, school districts and similar issuers.  Included in the municipal bond portfolio at June 30, 2017 and December 31, 2016 were $4.28 billion and $5.16 billion, respectively, of pre-refunded bonds, which are bonds for which states or municipalities have established irrevocable trusts, almost exclusively comprised of U.S. Treasury securities and obligations of U.S. government and government agencies and authorities.  These trusts were created to fund the payment of principal and interest due under the bonds.  The irrevocable trusts are verified as to their sufficiency by an independent verification agent of the underwriter, issuer or trustee.  All of the Company’s holdings of securities issued by Puerto Rico and related entities have been pre-refunded and therefore are defeased by U.S. Treasury securities.

The Company bases its investment decision on the underlying credit characteristics of the municipal security.  While its municipal bond portfolio includes a number of securities that were enhanced by third-party insurance for the payment of principal and interest in the event of an issuer default, the Company does not rely on enhanced credit characteristics provided by such third-party insurance as part of its investing decisions.  Of the insured municipal securities in the Company’s investment portfolio at June 30, 2017, approximately 99% were rated at “A3” or above, and approximately 92% were rated at “Aa3” or above, without the benefit of insurance.  The Company believes that a loss of the benefit of insurance would not result in a material adverse impact on the Company’s results of operations, financial position or liquidity, due to the underlying credit strength of the issuers of the securities, as well as the Company’s ability and intent to hold the securities.  The average credit rating of the underlying issuers of these securities was “Aa2” at June 30, 2017.  The average credit rating of the entire municipal bond portfolio was “Aa1” at June 30, 2017, with and without the enhancement provided by third-party insurance.

Mortgage-Backed Securities, Collateralized Mortgage Obligations and Pass-Through Securities

The Company’s fixed maturity investment portfolio at June 30, 2017 and December 31, 2016 included $1.77 billion and $1.71 billion, respectively, of residential mortgage-backed securities, which include pass-through securities and collateralized mortgage obligations (CMOs), all of which are subject to prepayment risk (either shortening or lengthening of duration).  While prepayment risk for securities and its effect on income cannot be fully controlled, particularly when interest rates move dramatically, the Company’s investment strategy generally favors securities that reduce this risk within expected interest rate

ranges.  Included in the totals at June 30, 2017 and December 31, 2016 were $527 million and $563 million, respectively, of GNMA, FNMA, FHLMC (excluding FHA project loans) and Canadian government guaranteed residential mortgage-backed pass-through securities classified as available for sale.  Also included in those totals were residential CMOs classified as available for sale with a fair value of $1.24 billion and $1.15 billion at June 30, 2017 and December 31, 2016, respectively. Approximately 51% of the Company’s CMO holdings at both June 30, 2017 and December 31, 2016 were guaranteed by or fully collateralized by securities issued by GNMA, FNMA or FHLMC.  The average credit rating of the $603 million and $566 million of non-guaranteed CMO holdings was “A3” and “Baa2” at June 30, 2017 and December 31, 2016, respectively.  The average credit rating of all of the above securities was “Aa2” at both June 30, 2017 and December 31, 2016.  For further discussion regarding the Company’s investments in residential CMOs, see “Part II—Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Investment Portfolio” in the Company’s 2016 Annual Report as updated by the Company’s Current Report on Form 8-K filed on June 20, 2017.

Equity Securities Available for Sale, Real Estate and Short-Term Investments

See note 1 of notes to the consolidated financial statements in the Company’s 2016 Annual Report as updated by the Company’s Current Report on Form 8-K filed on June 20, 2017 for further information about these invested asset classes.

Other Investments

The Company also invests in private equity limited partnerships, hedge funds and real estate partnerships and joint ventures.  Also included in other investments are non-public common and preferred equities and derivatives.  These asset classes have historically provided a higher return than fixed maturities but are subject to more volatility.  At June 30, 2017 and December 31, 2016, the carrying value of the Company’s other investments was $3.51 billion and $3.45 billion, respectively.

CATASTROPHE REINSURANCE COVERAGE

The Company’s catastrophe reinsurance coverage is discussed in the “Catastrophe Reinsurance” section of “Part I — Item 1 — Business” in the Company’s 2016 Annual Report as updated by the Company’s Current Report on Form 8-K filed on June 20, 2017.  Except as discussed below, there have been no material changes to the Company’s catastrophe reinsurance coverage from that reported in the Company’s 2016 Annual Report as updated by the Company’s Current Report on Form 8-K filed on June 20, 2017.

Catastrophe Bonds. With respect to the Company’s indemnity reinsurance agreement with Long Point Re III Ltd., the attachment point and maximum limit were reset as required annually to adjust the expected loss of the layer within a predetermined range.  For the period May 16, 2017 through and including May 15, 2018, the Company will be entitled to begin recovering amounts under this reinsurance agreement if the covered losses in the covered area for a single occurrence reach an initial attachment amount of $2.346 billion.  The full $300 million coverage amount is available on a proportional basis until such covered losses reach a maximum $2.846 billion.

Other Catastrophe Reinsurance Treaties.  Catastrophe reinsurance treaties that renewed on July 1, 2017 were as follows:

·Northeast Property Catastrophe Excess-of-Loss Reinsurance Treaty.  This provides up to $800 million part of $850 million of coverage, subject to a $2.25 billion retention, for certain losses arising from hurricanes, tornadoes, hail storms, earthquakes and winter storm or freeze losses from Virginia to Maine for the period July 1, 2017 through and including June 30, 2018.  Losses from a covered event (occurring over several days) anywhere in the United States, Canada, the Caribbean and Mexico and waters contiguous thereto may be used to satisfy the retention.  Recoveries under the catastrophe bonds (if any) would be first applied to reduce losses subject to this treaty.

·Middle Market Earthquake Catastrophe Excess-of-Loss Reinsurance Treaty. This treaty provides for up to $150 million part of $165 million of coverage, subject to an $80 million retention, for losses arising from an earthquake, including fire following and sprinkler leakage incurred under policies written by Technology, Public Sector Services and Commercial Accounts in the Company’s Business Insurance segment for the period July 1, 2017 through and including June 30, 2018.

64

MANAGEMENT’S DISCUSSION AND ANALYSIS, Continued

·Canadian Property Catastrophe Excess-of-Loss Reinsurance Treaty.  This treaty, effective for the period July 1, 2017 through and including June 30, 2018, covers the accumulation of net property losses arising out of one occurrence on business written by the Company’s Canadian businesses.  The treaty covers all property written by the Company’s Canadian businesses, including, but not limited to, habitational property, commercial property, inland marine, ocean marine and auto physical damages exposures, with respect to risks located worldwide.  The treaty provides coverage for 50% of losses in excess of C$100 million (US$77 million at June 30, 2017), up to C$200 million (US$154 million at June 30, 2017) and for 100% of losses in excess of C$200 million (US$154 million at June 30, 2017), up to C$600 million (US$462 million at June 30, 2017).

The Company regularly reviews its catastrophe reinsurance coverage and may adjust such coverage in the future.

REINSURANCE RECOVERABLES

For a description of the Company’s reinsurance recoverables, refer to “Part II—Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Reinsurance Recoverables” in the Company’s 2016 Annual Report as updated by the Company’s Current Report on Form 8-K filed on June 20, 2017.

The following table summarizes the composition of the Company’s reinsurance recoverables:

(in millions)	June 30, 2017			December 31, 2016
Gross reinsurance recoverables on paid and unpaid claims and claim adjustment expenses	$	3,076		$	3,181
Allowance for uncollectible reinsurance	(114		)	(116		)
Net reinsurance recoverables	2,962			3,065
Mandatory pools and associations	2,064			2,054
Structured settlements	3,124			3,168
Total reinsurance recoverables	$	8,150		$	8,287

The $103 million decline in net reinsurance recoverables from December 31, 2016 primarily reflected the impacts of cash collections in the first six months of 2017, including the settlement of certain disputes as discussed in more detail in note 13 of notes to the unaudited consolidated financial statements.

OUTLOOK

The following discussion provides outlook information for certain key drivers of the Company’s results of operations and capital position.

Premiums.  The Company’s earned premiums are a function of net written premium volume.  Net written premiums comprise both renewal business and new business and are recognized as earned premium over the life of the underlying policies. When business renews, the amount of net written premiums associated with that business may increase or decrease (renewal premium change) as a result of increases or decreases in rate and/or insured exposures, which the Company considers as a measure of units of exposure (such as the number and value of vehicles or properties insured).  Net written premiums from both renewal and new business, and therefore earned premiums, are impacted by competitive market conditions as well as general economic conditions, which, particularly in the case of Business Insurance, affect audit premium adjustments, policy endorsements and mid-term cancellations.  Property and casualty insurance market conditions are expected to remain competitive.  Net written premiums may also be impacted by the structure of reinsurance programs and related costs, as well as changes in foreign currency exchange rates.

Overall, the Company expects retention levels (the amount of expiring premium that renews, before the impact of renewal premium changes) will remain strong by historical standards during the remainder of 2017 and into 2018.  In Business Insurance, the Company expects that domestic renewal premium changes during the remainder of 2017 and into 2018 will remain positive and will be broadly consistent with the levels attained in the first six months of 2017. In Bond & Specialty Insurance, the Company expects that renewal premium changes with respect to domestic management liability business during the remainder of 2017 and into 2018 will remain positive, but will be slightly lower than the levels attained in the first six months of 2017.  With respect to domestic surety business within Bond & Specialty Insurance, the Company expects that

65

THE TRAVELERS COMPANIES, INC. AND SUBSIDIARIES

MANAGEMENT’S DISCUSSION AND ANALYSIS, Continued

net written premium volume during the remainder of 2017 and into 2018 will be broadly consistent with the level attained in the same periods of 2016 and 2017.  In Personal Insurance, the Company expects that domestic Agency Auto renewal premium changes during the remainder of 2017 and into 2018 will remain positive and will be higher than the levels attained in the first six months of 2017, and domestic Agency Homeowners and Other renewal premium changes during the remainder of 2017 and into 2018 will remain positive and will be broadly consistent with the levels attained in the first six months of 2017.  The need for state regulatory approval for changes to personal property and casualty insurance prices, as well as competitive market conditions, may impact the timing and extent of renewal premium changes.  Given the relatively smaller amount of premium that the Company generates from outside the United States and the transactional nature of some of those markets, particularly Lloyd’s, international renewal premium changes in each segment during the remainder of 2017 and into 2018 could be somewhat higher, broadly consistent with or somewhat lower than the levels attained in the first six months of 2017.

Property and casualty insurance market conditions are expected to remain competitive during the remainder of 2017 and into 2018 for new business.  In each of the Company’s business segments, new business generally has less of an impact on underwriting profitability than renewal business, given the volume of new business relative to renewal business.  However, in periods of meaningful increases in new business, despite its positive impact on underwriting gains over time, the impact of higher new business levels may negatively impact the combined ratio for a period of time.

General economic and geopolitical uncertainty regarding a variety of domestic and international matters, such as the political and regulatory environment, the U.S. Federal budget and potential changes in tax laws in the United States, the repeal, replacement or modification of the Affordable Care Act, economic uncertainty in the United States and in various parts of the world, the United Kingdom’s withdrawal from the European Union, rapid changes in commodity prices, such as in oil, and fluctuations in interest rates and foreign currency exchange rates, has added to the uncertainty regarding economic conditions generally.  If economic conditions deteriorate, the resulting lower levels of economic activity could impact exposure changes at renewal and the Company’s ability to write business at acceptable rates.  Additionally, lower levels of economic activity could adversely impact audit premium adjustments, policy endorsements and mid-term cancellations after policies are written.  All of the foregoing, in turn, could adversely impact net written premiums during the remainder of 2017 and into 2018, and because earned premiums are a function of net written premiums, earned premiums could be adversely impacted on a lagging basis.

Underwriting Gain/Loss.  The Company’s underwriting gain/loss can be significantly impacted by catastrophe losses and net favorable or unfavorable prior year reserve development, as well as underlying underwriting margins.

Catastrophe and non-catastrophe weather-related losses are inherently unpredictable from period to period.  The Company’s results of operations could be adversely impacted if significant catastrophe and non-catastrophe weather-related losses occur.

For a number of years, the Company’s results have included significant amounts of net favorable prior year reserve development driven by better than expected loss experience.  However, given the inherent uncertainty in estimating claims and claim adjustment expense reserves, loss experience could develop such that the Company recognizes higher or lower levels of favorable prior year reserve development, no favorable prior year reserve development or unfavorable prior year reserve development in future periods.  In addition, the ongoing review of prior year claims and claim adjustment expense reserves, or other changes in current period circumstances, may result in the Company revising current year loss estimates upward or downward in future periods of the current year.

It is possible that changes in economic conditions could lead to higher inflation than the Company had anticipated, which could in turn lead to an increase in the Company’s loss costs and the need to strengthen claims and claim adjustment expense reserves.  These impacts of inflation on loss costs and claims and claim adjustment expense reserves could be more pronounced for those lines of business that require a relatively longer period of time to finalize and settle claims for a given accident year and, accordingly, are relatively more inflation sensitive.  For a further discussion, see “Part I—Item 1A—Risk Factors—If actual claims exceed our claims and claim adjustment expense reserves, or if changes in the estimated level of claims and claim adjustment expense reserves are necessary, including as a result of, among other things, changes in the legal, regulatory and economic environments in which the Company operates, our financial results could be materially and adversely affected,” and “Changes in U.S. tax laws or in the tax laws of other jurisdictions in which we operate could adversely impact us” in the Company’s 2016 Annual Report.

THE TRAVELERS COMPANIES, INC. AND SUBSIDIARIES

MANAGEMENT’S DISCUSSION AND ANALYSIS, Continued

In Business Insurance, the Company expects underlying underwriting margins and the underlying combined ratio during the remainder of 2017 and into 2018 will be broadly consistent with those in the same periods of 2016 and 2017, reflecting the modest impact of loss trends in excess of earned pricing offset by more normalized levels of non-catastrophe weather-related losses and other loss activity.

In Bond & Specialty Insurance, the Company expects underlying underwriting margins and the underlying combined ratio during the remainder of 2017 and into 2018 will be broadly consistent with those in the same periods of 2016 and 2017.

In Personal Insurance, the Company expects underlying underwriting margins during the remainder of 2017 and into 2018 will be higher than in the same periods of 2016 and 2017, and the underlying combined ratio during the remainder of 2017 and into 2018 will be lower than in the same periods of 2016 and 2017.  In Agency Automobile, the Company expects that underlying underwriting margins and the underlying combined ratio will improve during the remainder of 2017 and into 2018 compared with the same periods of 2016 and 2017, reflecting actions taken to improve profitability, as well as the timing impact of higher loss trends for bodily injury liability coverages that were recognized in the last half of 2016.  In Agency Homeowners and Other, the Company expects that underlying underwriting margins will be slightly higher and the underlying combined ratio will be slightly lower during the remainder of 2017 and into 2018 than in the same periods of 2016 and 2017, reflecting more normalized levels of non-catastrophe weather-related losses and other loss activity.

Investment Portfolio.  The Company expects to continue to focus its investment strategy on maintaining a high-quality investment portfolio and a relatively short average effective duration.  The average effective duration of fixed maturities and short-term securities was 4.2 (4.6 excluding short-term securities) at June 30, 2017.  From time to time, the Company enters into short positions in U.S. Treasury futures contracts to manage the duration of its fixed maturity portfolio.  At June 30, 2017, the Company had $400 million notional value of open U.S. Treasury futures contracts.  The Company continually evaluates its investment alternatives and mix.  Currently, the majority of the Company’s investments are comprised of a widely diversified portfolio of high-quality, liquid, taxable U.S. government, tax-exempt U.S. municipal and taxable corporate and U.S. agency mortgage-backed bonds.

The Company also invests much smaller amounts in equity securities, real estate, private equity limited partnerships, hedge funds, and real estate partnerships and joint ventures.  These investment classes have the potential for higher returns but also the potential for higher degrees of risk, including less stable rates of return and less liquidity.

Net investment income is a material contributor to the Company’s results of operations.  Based on the current interest rate environment, which remains very low by historical standards, the Company estimates that the impact of lower reinvestment yields on fixed maturity investments, partially offset by the impact of slightly higher levels of fixed maturities combined with higher short-term investment yields could, during the remainder of 2017 result in approximately $15 million of lower after-tax net investment income, and into 2018, could result in approximately $10 million of lower after-tax net investment income from those portfolios on a quarterly basis as compared to the corresponding quarters of 2016 and 2017.  The impact of future market conditions on net investment income from the non-fixed maturity investment portfolio during the remainder of 2017 and into 2018 is hard to predict.  If general economic conditions and/or investment market conditions deteriorate during the remainder of 2017 and into 2018, the Company could experience a reduction in net investment income and/or significant realized investment losses, including impairments.

The Company had a net pre-tax unrealized investment gain of $1.43 billion ($931 million after-tax) in its fixed maturity investment portfolio at June 30, 2017.  While the Company does not attempt to predict future interest rate movements, a rising interest rate environment would reduce the market value of fixed maturity investments and, therefore, reduce shareholders’ equity, and a declining interest rate environment would have the opposite effects.  The Company’s investment portfolio has benefited from certain tax exemptions (primarily those related to interest from municipal bonds) and certain other tax laws, including, but not limited to, those governing dividends-received deductions and tax credits (such as foreign tax credits). Changes in these laws could adversely impact the value of the Company’s investment portfolio. See “Changes in U.S. tax laws or in the tax laws of other jurisdictions in which we operate could adversely impact us” included in “Part I—Item 1A—Risk Factors” in the Company’s 2016 Annual Report.

In the second quarter of 2017, the Company had net pre-tax realized investment gains of $80 million, which were primarily driven by gains on sales of equity securities.  At June 30, 2017, the carrying value of the Company’s equity securities was $700 million, which included $142 million of net pre-tax unrealized gains.  During the remainder of 2017, the Company may realize additional gains through the sales of equity securities.

MANAGEMENT’S DISCUSSION AND ANALYSIS, Continued

For further discussion of the Company’s investment portfolio, see “Investment Portfolio” herein.  For a discussion of the risks to the Company’s business during or following a financial market disruption and risks to the Company’s investment portfolio, see the risk factors entitled “During or following a period of financial market disruption or an economic downturn, our business could be materially and adversely affected” and “Our investment portfolio is subject to credit and interest rate risk, and may suffer reduced returns or material realized or unrealized losses” included in “Part I—Item 1A—Risk Factors” in the Company’s 2016 Annual Report.  For a discussion of the risks to the Company’s investments from foreign currency exchange rate fluctuations, see the risk factor entitled “We are also subject to a number of additional risks associated with our business outside the United States” included in “Part I—Item 1A—Risk Factors” in the Company’s 2016 Annual Report and see “Part II—Item 7A—Quantitative and Qualitative Disclosures About Market Risk—Foreign Currency Exchange Rate Risk” in the Company’s 2016 Annual Report.

Capital Position. The Company believes it has a strong capital position and, as part of its ongoing efforts to create shareholder value, expects to continue to return capital not needed to support its business operations to its shareholders.  The Company expects that, generally over time, the combination of dividends to common shareholders and common share repurchases will likely not exceed net income.  In addition, the timing and actual number of shares to be repurchased in the future will depend on a variety of additional factors, including the Company’s financial position, earnings, share price, catastrophe losses, maintaining capital levels commensurate with the Company’s desired ratings from independent rating agencies, funding of the Company’s qualified pension plan, capital requirements of the Company’s operating subsidiaries, legal requirements, regulatory constraints, other investment opportunities (including mergers and acquisitions and related financings), market conditions and other factors.  For information regarding the Company’s common share repurchases in 2017, see “Liquidity and Capital Resources.”  As a result of the Company’s business outside of the United States, primarily in Canada, the United Kingdom (including Lloyd’s), the Republic of Ireland and Brazil, the Company’s capital is also subject to the effects of changes in foreign currency exchange rates.  For example, strengthening of the U.S. dollar in comparison to other currencies could result in a reduction of shareholders’ equity.  For additional discussion of the Company’s foreign exchange market risk exposure, see “Part II—Item 7A—Quantitative and Qualitative Disclosures About Market Risk” in the Company’s 2016 Annual Report.

Many of the statements in this “Outlook” section are forward-looking statements, which are subject to risks and uncertainties that are often difficult to predict and beyond the Company’s control.  Actual results could differ materially from those expressed or implied by such forward-looking statements.  Further, such forward-looking statements speak only as of the date of this report and the Company undertakes no obligation to update them.  See “—Forward Looking Statements.”  For a discussion of potential risks and uncertainties that could impact the Company’s results of operations or financial position, see “Part I—Item 1A—Risk Factors” in the Company’s 2016 Annual Report and “Critical Accounting Estimates.”

LIQUIDITY AND CAPITAL RESOURCES

Liquidity is a measure of a company’s ability to generate sufficient cash flows to meet the cash requirements of its business operations and to satisfy general corporate purposes when needed.

Operating Company Liquidity.  The liquidity requirements of the Company’s insurance subsidiaries are met primarily by funds generated from premiums, fees, income received on investments and investment maturities.  For further discussion of operating company liquidity, see “Part II—Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources” in the Company’s 2016 Annual Report as updated by the Company’s Current Report on Form 8-K filed on June 20, 2017.

Holding Company Liquidity.  TRV’s liquidity requirements primarily include shareholder dividends, debt servicing, common share repurchases and, from time to time, contributions to its qualified domestic pension plan.  At June 30, 2017, TRV held total cash and short-term invested assets in the United States aggregating $2.55 billion and having a weighted average maturity of 59 days.  TRV has established a holding company liquidity target equal to its estimated annual pre-tax interest expense and common shareholder dividends (currently approximately $1.1 billion).  TRV’s holding company liquidity of $2.55 billion at June 30, 2017, which included net proceeds from the recent issuance of senior notes described below, exceeded this target and it is the opinion of the Company’s management that these assets are sufficient to meet TRV’s current liquidity requirements.

TRV is not dependent on dividends or other forms of repatriation from its foreign operations to support its liquidity needs.  U.S. income taxes have not been recognized on substantially all of the Company’s foreign operations’ undistributed earnings as of June 30, 2017, as such earnings are intended to be permanently reinvested in those operations.  Furthermore, taxes paid

68

THE TRAVELERS COMPANIES, INC. AND SUBSIDIARIES

MANAGEMENT’S DISCUSSION AND ANALYSIS, Continued

to foreign governments on these earnings may be used as credits against the U.S. tax on dividend distributions if such earnings were to be distributed to the holding company.  The amount of undistributed earnings from foreign operations and related taxes on those undistributed earnings were not material to the Company’s financial position or liquidity at June 30, 2017.

TRV has a shelf registration statement filed with the Securities and Exchange Commission (SEC) that expires on June 17, 2019 which permits it to issue securities from time to time.  TRV also has a $1.0 billion line of credit facility with a syndicate of financial institutions that expires on June 7, 2018.  This line of credit also supports TRV’s $800 million commercial paper program.  At June 30, 2017, the Company had no commercial paper outstanding.  TRV is not reliant on its commercial paper program to meet its operating cash flow needs.

The Company utilized uncollateralized letters of credit issued by major banks with an aggregate limit of approximately $244 million, to provide a portion of the capital needed to support its obligations at Lloyd’s at June 30, 2017.  If uncollateralized letters of credit are not available at a reasonable price or at all in the future, the Company can collateralize these letters of credit or may have to seek alternative means of supporting its obligations at Lloyd’s, which could include utilizing holding company funds on hand.

On March 13, 2017, the Company announced an agreement to acquire Simply Business, a leading digital provider of insurance policies to small businesses in the United Kingdom, for total consideration of approximately $490 million, which includes the repayment of debt and other obligations at the completion of the transaction.  The transaction is expected to close in the third quarter of 2017, subject to regulatory approvals and other customary closing conditions.  The Company will use a portion of the net proceeds from the issuance of senior notes in May 2017 (described in more detail in note 8 of notes to the unaudited consolidated financial statements) and internal resources to fund this transaction.

On December 15, 2017, the Company’s $450 million, 5.75% senior notes will mature.  The Company will use a portion of the proceeds from the issuance of senior notes in May 2017 (described in more detail in note 8 of notes to the unaudited consolidated financial statements) to fund this maturity.

Operating Activities

Net cash flows provided by operating activities in the first six months of 2017 and 2016 were $1.59 billion and $1.29 billion, respectively.  Cash flows in the first six months of 2016 included the Company’s $524 million payment in the second quarter of 2016 related to the settlement of the PPG Industries, Inc. litigation as described in more detail in the “Asbestos Claims and Litigation” section herein.

Investing Activities

Net cash flows used in investing activities in the first six months of 2017 and 2016 were $1.02 billion and $91 million, respectively.  The Company’s consolidated total investments at June 30, 2017 increased by $1.84 billion, or 3% over year-end 2016, primarily reflecting the impacts of net cash flows provided by operating activities, net proceeds from the issuance of debt and an increase in the unrealized appreciation of investments, partially offset by common share repurchases, dividends paid to shareholders and the repayment of debt.

Financing Activities

Net cash flows used in financing activities in the first six months of 2017 and 2016 were $550 million and $1.31 billion, respectively.  The totals in both periods primarily reflected common share repurchases, dividends paid to shareholders and the payment of debt, partially offset by the issuance of debt and the proceeds from employee stock option exercises.  Common share repurchases in the first six months of 2017 and 2016 were $761 million and $1.16 billion, respectively.  Share repurchases in the first six months of 2017 were lower than in the same period of 2016 as the Company moderated its share repurchases in the first quarter of 2017 to provide financing flexibility for the pending acquisition of Simply Business.

Dividends.  Dividends paid to shareholders were $389 million and $375 million in the first six months of 2017 and 2016, respectively.  The declaration and payment of future dividends to holders of the Company’s common stock will be at the discretion of the Company’s Board of Directors and will depend upon many factors, including the Company’s financial position, earnings, capital requirements of the Company’s operating subsidiaries, legal requirements, regulatory constraints and other factors as the Board of Directors deems relevant.  Dividends will be paid by the Company only if declared by its Board of Directors out of funds legally available, subject to any other restrictions that may be applicable to the Company.  On July 20, 2017, the Company announced that it declared a regular quarterly dividend of $0.72 per share, payable September

29, 2017 to shareholders of record on September 8, 2017.

Share Repurchase Authorization.  The Company’s Board of Directors has approved common share repurchase authorizations under which repurchases may be made from time to time in the open market, pursuant to pre-set trading plans meeting the requirements of Rule 10b5-1 under the Securities Exchange Act of 1934, in private transactions or otherwise.  The authorizations do not have a stated expiration date.  The timing and actual number of shares to be repurchased in the future will depend on a variety of factors, including the Company’s financial position, earnings, share price, catastrophe losses, maintaining capital levels commensurate with the Company’s desired ratings from independent rating agencies, funding of the Company’s qualified pension plan, capital requirements of the Company’s operating subsidiaries, legal requirements, regulatory constraints, other investment opportunities (including mergers and acquisitions and related financings), market conditions and other factors.  During the three months and six months ended June 30, 2017, the Company repurchased 3.8 million and 5.7 million shares, respectively, under its share repurchase authorization, for a total cost of $475 million and $700 million, respectively.  The average cost per share repurchased was $123.04 and $122.33, respectively.  On April 20, 2017, the Board of Directors approved a share repurchase authorization that added an additional $5.0 billion of repurchase capacity.  At June 30, 2017, the Company had $5.23 billion of capacity remaining under the share repurchase authorization.

Capital Structure.  The following table summarizes the components of the Company’s capital structure at June 30, 2017 and December 31, 2016.

On May 22, 2017, the Company issued $700 million aggregate principal amount of 4.00% senior notes that will mature on May 30, 2047.  See note 8 of notes to the unaudited consolidated financial statements for further discussion regarding the terms of the senior notes.  On June 2, 2017, the Company redeemed the remaining $107 million aggregate principal amount of its 6.25% Fixed-to-Floating Rate Junior Subordinated Debentures due 2067 at a price per debenture of 100% of the principal amount thereof, plus accrued and unpaid interest to the redemption date.

The following table provides a reconciliation of total capitalization presented in the foregoing table to total capitalization excluding net unrealized gains on investments.

MANAGEMENT’S DISCUSSION AND ANALYSIS, Continued

The debt-to-total capital ratio excluding net unrealized gains on investments is calculated by dividing (a) debt by (b) total capitalization excluding net unrealized gains and losses on investments, net of taxes.  Net unrealized gains and losses on investments can be significantly impacted by both interest rate movements and other economic factors.  Accordingly, in the opinion of the Company’s management, the debt-to-total capital ratio calculated on this basis provides another useful metric for investors to understand the Company’s financial leverage position.  The Company’s ratio of debt-to-total capital (excluding after-tax net unrealized investment gains) of 23.3% at June 30, 2017 was within the Company’s target range of 15% to 25%.

RATINGS

Ratings are an important factor in assessing the Company’s competitive position in the insurance industry.  The Company receives ratings from the following major rating agencies: A.M. Best Company (A.M. Best), Fitch Ratings (Fitch), Moody’s Investors Service (Moody’s) and Standard & Poor’s (S&P).  The following rating agency actions were taken with respect to the Company since April 20, 2017, the date on which the Company’s Form 10-Q for the quarter ended March 31, 2017 was filed with the SEC.   For additional discussion of ratings, see “Part I—Item 1—Business—Ratings” in the Company’s 2016 Annual Report as updated by the Company’s Current Report on Form 8-K filed on June 20, 2017.

·On June 19, 2017, Fitch affirmed all ratings of the Company.  The outlook for all ratings is stable.

·On July 13, 2017, Moody’s affirmed all ratings of the Company.  The outlook for all ratings is stable.

CRITICAL ACCOUNTING ESTIMATES

For a description of the Company’s critical accounting estimates, refer to “Part II—Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Estimates” in the Company’s 2016 Annual Report as updated by the Company’s Current Report on Form 8-K filed on June 20, 2017.  The Company considers its most significant accounting estimates to be those applied to claims and claim adjustment expense reserves and related reinsurance recoverables, investment valuation and impairments, and goodwill and other intangible assets impairments. Except as shown in the table below, there have been no material changes to the Company’s critical accounting estimates since December 31, 2016.

Claims and Claim Adjustment Expense Reserves

The table below displays the Company’s gross claims and claim adjustment expense reserves by product line.  Because the establishment of claims and claim adjustment expense reserves is an inherently uncertain process involving estimates, currently established claims and claim adjustment expense reserves may change.  The Company reflects adjustments to the reserves in the results of operations in the period the estimates are changed.  These changes in estimates could result in income statement charges that could be material to the Company’s operating results in future periods.  In particular, a portion of the Company’s gross claims and claim adjustment expense reserves (totaling $1.78 billion at June 30, 2017) are for asbestos and environmental claims and related litigation.  Asbestos and environmental reserves are included in the General liability, Commercial multi-peril and International and other lines in the summary table below.  While the ongoing review of asbestos and environmental claims and associated liabilities considers the inconsistencies of court decisions as to coverage, plaintiffs’ expanded theories of liability and the risks inherent in complex litigation and other uncertainties, in the opinion of the Company’s management, it is possible that the outcome of the continued uncertainties regarding these claims could result in liability in future periods that differs from current reserves by an amount that could be material to the Company’s future operating results. Asbestos and environmental reserves are discussed separately; see “Asbestos Claims and Litigation”, “Environmental Claims and Litigation” and “Uncertainty Regarding Adequacy of Asbestos and Environmental Reserves” in this report.

Gross claims and claim adjustment expense reserves by product line were as follows:

The $625 million increase in gross claims and claim adjustment expense reserves since December 31, 2016 primarily reflected the impacts of (i) higher volumes of insured exposures and loss cost trends for the current accident year and (ii) catastrophe losses incurred in the first six months of 2017, partially offset by the impacts of (iii) net favorable prior year reserve development and (iv) payments related to operations in runoff.

FUTURE APPLICATION OF ACCOUNTING STANDARDS

See note 1 of notes to the unaudited consolidated financial statements contained in this quarterly report and in the Company’s 2016 Annual Report as updated by the Company’s Current Report on Form 8-K filed on June 20, 2017 for a discussion of recently issued accounting pronouncements.

FORWARD-LOOKING STATEMENTS

This report contains, and management may make, certain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995.  All statements, other than statements of historical facts, may be forward-looking statements.  Words such as “may,” “will,” “should,” “likely,” “anticipates,” “expects,” “intends,” “plans,” “projects,” “believes,” “estimates” and similar expressions are used to identify these forward-looking statements.  These statements include, among other things, the Company’s statements about:

·the Company’s outlook and its future results of operations and financial condition (including, among other things, anticipated premium volume, premium rates, margins, net and core income, investment income and performance, loss costs, return on equity, core return on equity and expected current returns and combined ratios);

·share repurchase plans;

·future pension plan contributions;

·the sufficiency of the Company’s asbestos and other reserves;

·the impact of emerging claims issues as well as other insurance and non-insurance litigation;

·the cost and availability of reinsurance coverage;

·catastrophe losses;

·the impact of investment, economic (including inflation, potential changes in tax law and rapid changes in commodity prices, such as a significant decline in oil and gas prices, as well as fluctuations in foreign currency exchange rates) and underwriting market conditions;

·strategic initiatives to improve profitability and competitiveness; and

·the potential closing date and impact of the Company’s acquisition of Simply Business.

The Company cautions investors that such statements are subject to risks and uncertainties, many of which are difficult to predict and generally beyond the Company’s control, that could cause actual results to differ materially from those expressed in, or implied or projected by, the forward-looking information and statements.

72

THE TRAVELERS COMPANIES, INC. AND SUBSIDIARIES

FORWARD-LOOKING STATEMENTS, Continued

Some of the factors that could cause actual results to differ include, but are not limited to, the following:

·catastrophe losses could materially and adversely affect the Company’s results of operations, its financial position and/or liquidity, and could adversely impact the Company’s ratings, the Company’s ability to raise capital and the availability and cost of reinsurance;

·if actual claims exceed the Company’s claims and claim adjustment expense reserves, or if changes in the estimated level of claims and claim adjustment expense reserves are necessary, including as a result of, among other things, changes in the legal, regulatory and economic environments in which the Company operates, the Company’s financial results could be materially and adversely affected;

·during or following a period of financial market disruption or an economic downturn, the Company’s business could be materially and adversely affected;

·the Company’s investment portfolio is subject to credit risk, and may suffer material realized or unrealized losses.  The Company’s investment portfolio may also suffer reduced or low returns, particularly if interest rates remain at historically low levels for a prolonged period of time or decline further as a result of actions taken by central banks (a risk which potentially could be increased by, among other things, the United Kingdom’s withdrawal from the European Union);

·the Company’s business could be harmed because of its potential exposure to asbestos and environmental claims and related litigation;

·the intense competition that the Company faces, and the impact of innovation, technological change and changing customer preferences on the insurance industry and the markets in which the Company operates, could harm its ability to maintain or increase its business volumes and its profitability;

·disruptions to the Company’s relationships with its independent agents and brokers or the Company’s inability to manage effectively a changing distribution landscape could adversely affect the Company;

·the Company is exposed to, and may face adverse developments involving, mass tort claims such as those relating to exposure to potentially harmful products or substances;

·the effects of emerging claim and coverage issues on the Company’s business are uncertain;

·the Company may not be able to collect all amounts due to it from reinsurers, reinsurance coverage may not be available to the Company in the future at commercially reasonable rates or at all and the Company is exposed to credit risk related to its structured settlements;

·the Company is also exposed to credit risk in certain of its insurance operations and with respect to certain guarantee or indemnification arrangements that it has with third parties;

·within the United States, the Company’s businesses are heavily regulated by the states in which it conducts business, including licensing and supervision, and changes in regulation may reduce the Company’s profitability and limit its growth;

·a downgrade in the Company’s claims-paying and financial strength ratings could adversely impact the Company’s business volumes, adversely impact the Company’s ability to access the capital markets and increase the Company’s borrowing costs;

·the inability of the Company’s insurance subsidiaries to pay dividends to the Company’s holding company in sufficient amounts would harm the Company’s ability to meet its obligations, pay future shareholder dividends or make future share repurchases;

·the Company’s efforts to develop new products or expand in targeted markets may not be successful and may create enhanced risks;

·the Company may be adversely affected if its pricing and capital models provide materially different indications than actual results;

·the Company’s business success and profitability depend, in part, on effective information technology systems and on continuing to develop and implement improvements in technology;

·if the Company experiences difficulties with technology, data and network security (including as a result of cyber attacks), outsourcing relationships, or cloud-based technology, the Company’s ability to conduct its business could be negatively impacted;

·changes in U.S. tax laws or in the tax laws of other jurisdictions in which the Company operates could adversely impact the Company;

·the Company is also subject to a number of additional risks associated with its business outside the United States, including foreign currency exchange fluctuations and restrictive regulations, as well as the risks and uncertainties associated with the United Kingdom’s withdrawal from the European Union;

73

THE TRAVELERS COMPANIES, INC. AND SUBSIDIARIES

FORWARD-LOOKING STATEMENTS, Continued

·regulatory changes outside of the United States, including in Canada and the European Union, could adversely impact the Company’s results of operations and limit its growth;

·loss of or significant restrictions on the use of particular types of underwriting criteria, such as credit scoring, or other data or methodologies, in the pricing and underwriting of the Company’s products could reduce the Company’s future profitability;

·acquisitions and integration of acquired businesses may result in operating difficulties and other unintended consequences;

·the Company could be adversely affected if its controls designed to ensure compliance with guidelines, policies and legal and regulatory standards are not effective;

·the Company’s businesses may be adversely affected if it is unable to hire and retain qualified employees;

·intellectual property is important to the Company’s business, and the Company may be unable to protect and enforce its own intellectual property or the Company may be subject to claims for infringing the intellectual property of others;

·changes in federal regulation could impose significant burdens on the Company and otherwise adversely impact the Company’s results;

·changes to existing U.S. accounting standards may adversely impact the Company’s reported results; and

·the Company’s share repurchase plans depend on a variety of factors, including the Company’s financial position, earnings, share price, catastrophe losses, maintaining capital levels commensurate with the Company’s desired ratings from independent rating agencies, funding of the Company’s qualified pension plan, capital requirements of the Company’s operating subsidiaries, legal requirements, regulatory constraints, other investment opportunities (including mergers and acquisitions and related financings), market conditions and other factors.

For the Company’s disclosures about market risk, please see “Part II—Item 7A—Quantitative and Qualitative Disclosures About Market Risk” in the Company’s 2016 Annual Report filed with the SEC.  There have been no material changes to the Company’s disclosures about market risk in Part II—Item 7A of the Company’s 2016 Annual Report.

Item 4. CONTROLS AND PROCEDURES

The Company maintains disclosure controls and procedures (as that term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (Exchange Act)) that are designed to ensure that information required to be disclosed in the Company’s reports under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to the Company’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures. Any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. The Company’s management, with the participation of the Company’s Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of

74

THE TRAVELERS COMPANIES, INC. AND SUBSIDIARIES

Item 4. CONTROLS AND PROCEDURES, Continued

the design and operation of the Company’s disclosure controls and procedures as of June 30, 2017.  Based upon that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer concluded that, as of June 30, 2017, the design and operation of the Company’s disclosure controls and procedures were effective to accomplish their objectives at the reasonable assurance level.

Except for internal controls over financial reporting related to the implementation of a new investment accounting system for private equity limited partnerships, hedge funds and real estate partnerships, there were no changes in the Company’s internal control over financial reporting (as that term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the quarter ended June 30, 2017 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.  Management reviewed and tested the effectiveness of the internal controls over financial reporting related to the implementation of the new investment accounting system and concluded they were effective.

The Company regularly seeks to identify, develop and implement improvements to its technology systems and business processes, some of which may affect its internal control over financial reporting. These changes may include such activities as implementing new, more efficient systems, updating existing systems or platforms, automating manual processes or utilizing technology developed by third parties.  These systems changes are often phased in over multiple periods in order to limit the implementation risk in any one period, and as each change is implemented the Company monitors its effectiveness as part of its internal control over financial reporting.

The Company’s Board of Directors has approved common share repurchase authorizations under which repurchases may be made from time to time in the open market, pursuant to pre-set trading plans meeting the requirements of Rule 10b5-1 under the Securities Exchange Act of 1934, in private transactions or otherwise.  The authorizations do not have a stated expiration date.  The timing and actual number of shares to be repurchased in the future will depend on a variety of factors, including the Company’s financial position, earnings, share price, catastrophe losses, maintaining capital levels commensurate with the Company’s desired ratings from independent rating agencies, funding of the Company’s qualified pension plan, capital requirements of the Company’s operating subsidiaries, legal requirements, regulatory constraints, other investment opportunities (including mergers and acquisitions and related financings), market conditions and other factors.

The Company acquired 1,803 shares for a total cost of approximately $0.2 million during the three months ended June 30, 2017 that were not part of the publicly announced share repurchase authorization.  These shares consisted of shares retained to cover payroll withholding taxes in connection with the vesting of restricted stock unit awards and performance share awards, and shares used by employees to cover the price of certain stock options that were exercised.

Item 5.   OTHER INFORMATION

Executive Ownership and Sales. All of the Company’s executive officers are subject to the Company’s executive stock ownership policy. For a summary of this policy as currently in effect, see “Compensation Discussion and Analysis — Stock Ownership Guidelines, Anti-Hedging and Pledging Policies, and Other Trading Restrictions” in the Company’s proxy statement filed with the SEC on March 31, 2017. From time to time, some of the Company’s executives may determine that it is advisable to diversify their investments for personal financial planning reasons, or may seek liquidity for other reasons, and may, in compliance with the stock ownership policy, sell shares of common stock of the Company on the open market, in private transactions or to the Company. To effect such sales, from time to time, some of the Company’s executives may enter into trading plans designed to comply with the Company’s Securities Trading Policy and the provisions of Rule 10b5-1 under the Securities Exchange Act of 1934. The trading plans will not reduce any of the executives’ ownership of the Company’s shares below the applicable executive stock ownership guidelines. The Company does not undertake any obligation to report Rule 10b5-1 plans that may be adopted by any employee or director of the Company in the future, or to report any modifications or termination of any publicly announced plan.

As of the date of this report, Jay S. Benet, Vice Chairman and Chief Financial Officer, was the only “named executive officer” (i.e., an executive officer named in the compensation disclosures in the Company’s most recent proxy statement filed with the SEC) that has entered into a Rule 10b5-1 trading plan that remains in effect.  Under the Company’s stock ownership guidelines, Mr. Benet has a target ownership level established as the lesser of 30,000 shares or the equivalent value of 300% of base salary (as such amount is calculated for purposes of the stock ownership guidelines).  See “Compensation Discussion and Analysis — Stock Ownership Guidelines, Anti-Hedging and Pledging Policies, and Other Trading Restrictions” in the Company’s proxy statement filed with the SEC on March 31, 2017.

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 Annual Report on Form 10-K for the year ended December 31, 2016 (the Company’s 2016 Annual Report) as updated by the Company’s Current Report on Form 8-K filed on June 20, 2017. The Form 8-K was filed to reclassify certain of the Company’s historical segment information to conform the presentation of such segment information to the manner in which the Company’s businesses have been managed beginning April 1, 2017 (as described in more detail below) and reflect the revised names and descriptions of certain businesses comprising these segments and other related changes.

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 March 13, 2017, the Company announced an agreement to acquire Simply Business, a leading digital provider of insurance policies to small businesses in the United Kingdom, for total consideration of approximately $490 million, which includes the repayment of debt and other obligations at the completion of the transaction.  The transaction is expected to close in the third quarter of 2017, subject to regulatory approvals and other customary closing conditions.  The Company will use a portion of the net proceeds from the issuance of senior notes in May 2017 (described in more detail in note 8) and internal resources to fund this transaction.

Adoption of Accounting Standards

Investments — Equity Method and Joint Ventures:  Simplifying the Transition to the Equity Method of Accounting

In March 2016, the Financial Accounting Standards Board (FASB) issued updated guidance that eliminates the requirement to retroactively apply the equity method of accounting when an investment that was previously accounted for using another method of accounting becomes qualified to apply the equity method due to an increase in the level of ownership interest or degree of influence.  If the investment was previously accounted for as an available-for-sale security, any related unrealized gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for the equity method is recognized through earnings.  The updated guidance was effective for reporting periods beginning after December 15, 2016, and was applied prospectively.  The adoption of this guidance did not have a material effect on the Company’s results of operations, financial position or liquidity.

Derivatives and Hedging:  Contingent Put and Call Options in Debt Instruments

In March 2016, the FASB issued updated guidance clarifying that when a call (put) option in a debt instrument can accelerate the repayment of principal on the debt instrument, a reporting entity does not need to assess whether the contingent event that triggers the ability to exercise the call (put) option is related to interest rates or credit risk in determining whether the option should be accounted for separately.  The updated guidance was effective for reporting periods beginning after December 15, 2016. The adoption of this guidance did not have a material effect on the Company’s results of operations, financial position or liquidity.

Compensation — Retirement Benefits: Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost

In March 2017, the FASB issued updated guidance to improve the presentation of net periodic pension cost and net periodic post retirement cost (net benefit costs). Net benefit costs comprise several components that reflect different aspects of an employer’s financial arrangements as well as the cost of benefits provided to employees.  The update requires that the employer service cost component be reported in the same lines as other employee compensation cost and that the other components (non-service costs) be presented separately from the service cost and outside of a subtotal of income from operations if one is presented.  The update also allows only the service cost component to be eligible for capitalization in assets when applicable.

The updated guidance is effective for reporting periods beginning after December 15, 2017. The update is to be applied retrospectively with respect to the presentation of service cost and non-service cost and prospectively with respect to applying the service cost only eligible for capitalization in assets guidance. Early adoption is permitted as of the first interim period of an annual period if an entity issues interim financial statements.

The Company adopted the updated guidance effective January 1, 2017. See note 12 which has been expanded to disclose the amount of service cost and non-service cost components of net periodic benefit cost and the line items in the consolidated statement of income in which such amounts are reported. The updated guidance with respect to only service costs being eligible for capitalization in assets was not applicable.

For information regarding accounting standards that the Company adopted during the years presented, see the “Adoption of Accounting Standards” section of note 1 of notes to the consolidated financial statements in the Company’s 2016 Annual Report as updated by the Company’s Current Report on Form 8-K filed on June 20, 2017.

Compensation — Stock Compensation: Scope of Modification Accounting

In May 2017, the FASB issued updated guidance related to a change to the terms or conditions (modification) of a share-based payment award.  The updated guidance provides that an entity should account for the effects of a modification unless the fair value and vesting conditions of the modified award and the classification of the modified award (equity or liability instrument) are the same as the original award immediately before the modification.

The updated guidance is effective for the quarter ending March 31, 2018.  The update is to be applied prospectively to an award modified on or after the adoption date. Early adoption is permitted in any interim periods for which financial statements have not yet been made available for issuance.

The Company adopted the updated guidance effective April 1, 2017. The adoption did not have an effect on the Company’s results of operations, financial position or liquidity.

Accounting Standards Not Yet Adopted

For information regarding accounting standards that the Company has not yet adopted, see the “Other Accounting Standards Not Yet Adopted” section of note 1 of notes to the consolidated financial statements in the Company’s 2016 Annual Report as updated by the Company’s Current Report on Form 8-K filed on June 20, 2017.

Nature of Operations

Effective April 1, 2017, the Company’s results are reported in the following three business segments — Business Insurance, Bond & Specialty Insurance and Personal Insurance, reflecting a change in the manner in which the Company’s businesses are managed as of that date, as well as the aggregation of products and services based on the type of customer, how the business is marketed and the manner in which risks are underwritten.  While the segmentation of the Company’s domestic businesses is unchanged, the Company’s international businesses, which were previously managed and reported in total within the Business and International Insurance segment, are now disaggregated by product type among the three newly aligned reportable business segments.  All prior periods presented have been reclassified to conform to this presentation.  In connection with these changes, the Company has revised the names and descriptions of certain businesses comprising the Company’s segments and has reflected other related changes.

The new reportable business segments are as follows:

Business Insurance

Business Insurance offers a broad array of property and casualty insurance and insurance related services to its customers, primarily in the United States, as well as in Canada, the United Kingdom, the Republic of Ireland, Brazil and throughout other parts of the world as a corporate member of Lloyd’s.

Unrealized losses for all fixed maturities and equity securities reported at fair value for which fair value is less than 80% of amortized cost at June 30, 2017 totaled $1 million, representing less than 1% of the combined fixed maturity and equity security portfolios on a pre-tax basis and less than 1% of shareholders’ equity on an after-tax basis.

Impairment Charges

Impairment charges included in net realized investment gains in the consolidated statement of income were $5 million and $4 million for the three months ended June 30, 2017 and 2016, respectively, and $7 million and $22 million for the six months ended June 30, 2017 and 2016, respectively.

The cumulative amount of credit losses on fixed maturities held at June 30, 2017 and 2016, that were recognized in the consolidated statement of income from other-than-temporary impairments (OTTI) and for which a portion of the OTTI was recognized in other comprehensive income (loss) in the consolidated balance sheet was $83 million and $88 million, respectively.  These credit losses represent less than 1% of the fixed maturity portfolio on a pre-tax basis and less than 1% of shareholders’ equity on an after-tax basis at both dates.  There were no significant changes in the credit component of OTTI during the six months ended June 30, 2017 and 2016 from that disclosed in note 3 of notes to the consolidated financial statements in the Company’s 2016 Annual Report as updated by the Company’s Current Report on Form 8-K filed on June 20, 2017.

Derivative Financial Instruments

From time to time, the Company enters into U.S. Treasury note futures contracts to modify the effective duration of specific assets within the investment portfolio.  U.S. Treasury futures contracts require a daily mark-to-market and settlement with the broker.  At both June 30, 2017 and December 31, 2016, the Company had $400 million notional value of open U.S. Treasury futures contracts.  Net realized investment losses related to U.S. Treasury futures contracts for the three months and six months ended June 30, 2017 and 2016 were not significant.

Fair Value Measurements

Fair Value Measurements disclosure

Fair Value Measurements disclosure [Text Block]

4.     FAIR VALUE MEASUREMENTS

The Company’s estimates of fair value for financial assets and financial liabilities are based on the framework established in the fair value accounting guidance.  The framework is based on the inputs used in valuation, gives the highest priority to quoted prices in active markets and requires that observable inputs be used in the valuations when available.  The disclosure of fair value estimates in the fair value accounting guidance hierarchy is based on whether the significant inputs into the valuation are observable.  In determining the level of the hierarchy in which the estimate is disclosed, the highest priority is given to unadjusted quoted prices in active markets and the lowest priority to unobservable inputs that reflect the Company’s significant market assumptions.  The level in the fair value hierarchy within which the fair value measurement is reported is based on the lowest level input that is significant to the measurement in its entirety.  The three levels of the hierarchy are as follows:

· Level 1 - Unadjusted quoted market prices for identical assets or liabilities in active markets that the Company has the ability to access.

· Level 2 - Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in inactive markets; or valuations based on models where the significant inputs are observable (e.g., interest rates, yield curves, prepayment speeds, default rates, loss severities, etc.) or can be corroborated by observable market data.

· Level 3 - Valuations based on models where significant inputs are not observable.  The unobservable inputs reflect the Company’s own assumptions about the inputs that market participants would use.

Valuation of Investments Reported at Fair Value in Financial Statements

The Company utilized a pricing service to estimate fair value measurements for approximately 98% of its fixed maturities at both June 30, 2017 and December 31, 2016.

While the vast majority of the Company’s fixed maturities are included in Level 2, the Company holds a number of municipal bonds and corporate bonds which are not valued by the pricing service and estimates the fair value of these bonds using an internal pricing matrix with some unobservable inputs that are significant to the valuation.  Due to the limited amount of observable market information, the Company includes the fair value estimates for these particular bonds in Level 3.  The fair value of the fixed maturities for which the Company used an internal pricing matrix was $108 million and $99 million at June 30, 2017 and December 31, 2016, respectively.  Additionally, the Company holds a small amount of other fixed maturity investments that have characteristics that make them unsuitable for matrix pricing.  For these fixed maturities, the Company obtains a quote from a broker (primarily the market maker).  The fair value of the fixed maturities for which the Company received a broker quote was $97 million and $85 million at June 30, 2017 and December 31, 2016, respectively.  Due to the disclaimers on the quotes that indicate that the price is indicative only, the Company includes these fair value estimates in Level 3.

For more information regarding the valuation of the Company’s fixed maturities, equity securities and other investments, see note 4 of notes to the consolidated financial statements in the Company’s 2016 Annual Report as updated by the Company’s Current Report on Form 8-K filed on June 20, 2017.

The following tables present the level within the fair value hierarchy at which the Company’s financial assets and financial liabilities are measured on a recurring basis.  An investment transferred between levels during a period is transferred at its fair value as of the beginning of that period.

(1) Intangible assets subject to amortization are comprised of fair value adjustments on claims and claim adjustment expense reserves, reinsurance recoverables and other contract and customer-related intangibles.  The time value of money and the risk adjustment (cost of capital) components of the intangible asset run off at different rates, and, as such, the amount recognized in income may be a net benefit in some periods and a net expense in other periods.

Amortization expense of intangible assets was $2 million for each of the three months ended June 30, 2017 and 2016, and $5 million for each of the six months ended June 30, 2017 and 2016.  Intangible asset amortization expense is estimated to be $4 million for the remainder of 2017, $8 million in 2018, $7 million in 2019, $5 million in 2020 and $5 million in 2021.

Reinsurance recoverables on unpaid losses at June 30, 2017 decreased by $104 million from December 31, 2016, primarily reflecting the impact of cash collections in the first six months of 2017, including the settlement of certain disputes as discussed in more detail in note 13.

Prior Year Reserve Development

The following disclosures regarding reserve development are on a “net of reinsurance” basis.

For the six months ended June 30, 2017 and 2016, estimated claims and claim adjustment expenses incurred included $214 million and $418 million, respectively, of net favorable development for claims arising in prior years, including $284 million and $468 million, respectively, of net favorable prior year reserve development impacting the Company’s results of operations and $25 million of accretion of discount in each period.

Business Insurance. Net favorable prior year reserve development in the second quarter of 2017 totaled $125 million, primarily driven by better than expected loss experience in the segment’s domestic operations in (i) the workers’ compensation product line for multiple accident years, (ii) the commercial multi-peril product line for liability coverages for multiple accident years and (iii) the general liability product line for both primary and excess coverages for multiple accident years (excluding an increase to environmental reserves discussed below).  Net favorable prior year reserve development in the second quarter of 2016 totaled $125 million, primarily driven by better than expected loss experience in the segment’s domestic operations in (i) the workers’ compensation product line for accident years 2006 and prior as well as accident year 2015 and (ii) the general liability product line for both primary and excess coverages for accident years 2011 and 2015 (excluding an increase to environmental reserves discussed below), as well as in the segment’s international operations in Europe.  These factors contributing to net favorable prior year reserve development in the second quarters of 2017 and 2016 were partially offset by $65 million and $82 million increases, respectively, to environmental reserves.

Net favorable prior year reserve development in the first six months of 2017 totaled $186 million, primarily driven by better than expected loss experience in the segment’s domestic operations in (i) the workers’ compensation product line for multiple accident years, (ii) the general liability product line (excluding the increase to environmental reserves) for both primary and excess coverages for multiple accident years and (iii) the commercial multi-peril product line for liability coverages for multiple accident years, partially offset by (iv) net unfavorable prior year reserve development in the segment’s international operations in Europe due to the U.K. Ministry of Justice’s “Ogden” discount rate adjustment applied to lump sum bodily injury payouts.  Net favorable development in the first six months of 2016 totaled $199 million, primarily driven by better than expected loss experience in the segment’s domestic operations in (i) the workers’ compensation product line for accident years 2006 and prior as well as accident year 2015, (ii) the general liability product line (excluding the increase to environmental reserves), related to both primary and excess coverages for accident years 2011, 2013 and 2015 and (iii) the commercial automobile product line for accident years 2010 and prior, as well as in the segment’s international operations in Europe and Canada.  These factors contributing to net favorable prior year reserve development in the first six months of 2017 and 2016 were partially offset by the $65 million and $82 million increases, respectively, to environmental reserves.

Bond & Specialty Insurance.  Net favorable prior year reserve development in the second quarter and first six months of 2017 totaled $78 million and $92 million, respectively, primarily driven by better than expected loss experience in the segment’s domestic operations in the general liability product line for accident years 2012 through 2015.  Net favorable prior year reserve development in the second quarter of 2016 totaled $159 million, primarily driven by better than expected loss experience in the segment’s domestic operations in (i) the fidelity and surety product line for accident years 2010, 2013 and 2014 and (ii) the general liability product line for accident years 2007 through 2011.  Net favorable prior year reserve development in the first six months of 2016 totaled $225 million, primarily driven by better than expected loss experience in the segment’s domestic operations in (i) the fidelity and surety product line for accident years 2010 through 2014 and (ii) the general liability product line for accident years 2007 through 2011.

Personal Insurance.  Net favorable prior year reserve development in the second quarter and first six months of 2017 totaled $0 and $6 million, respectively.  Net favorable prior year reserve development in the second quarter and first six months of 2016 totaled $4 million and $44 million, respectively. Net favorable prior year reserve development in the first six months of 2016 was primarily driven by better than expected loss experience in the segment’s domestic operations in (i) the Homeowners and Other product line for liability coverages for accident year 2014 and (ii) the Automobile product line for accident year 2014, as well as in the segment’s international operations in Canada.

Contingencies, Commitments and Guarantees disclosure

Contingencies, Commitments and Guarantees disclosure [Text Block]

13.          CONTINGENCIES, COMMITMENTS AND GUARANTEES

Contingencies

The major pending legal proceedings, other than ordinary routine litigation incidental to the business, to which the Company or any of its subsidiaries is a party or to which any of the Company’s properties is subject are described below.

Asbestos and Environmental Claims and Litigation

In the ordinary course of its insurance business, the Company has received and continues to receive claims for insurance arising under policies issued by the Company asserting alleged injuries and damages from asbestos- and environmental-related exposures that are the subject of related coverage litigation. The Company is defending asbestos- and environmental-related litigation vigorously and believes that it has meritorious defenses; however, the outcomes of these disputes are uncertain.  In this regard, the Company employs dedicated specialists and aggressive resolution strategies to manage asbestos and environmental loss exposure, including settling litigation under appropriate circumstances.  Currently, it is not possible to predict legal outcomes and their impact on the future development of claims and litigation relating to asbestos and environmental claims. Any such development will be affected by future court decisions and interpretations, as well as changes in applicable legislation. Because of these uncertainties, additional liabilities may arise for amounts in excess of the Company’s current insurance reserves. In addition, the Company’s estimate of ultimate claims and claim adjustment expenses may change. These additional liabilities or increases in estimates, or a range of either, cannot now be reasonably estimated and could result in income statement charges that could be material to the Company’s results of operations in future periods.

Other Proceedings Not Arising Under Insurance Contracts or Reinsurance Agreements

The Company is involved in other lawsuits, including lawsuits alleging extra-contractual damages relating to insurance contracts or reinsurance agreements, that do not arise under insurance contracts or reinsurance agreements.  The legal costs associated with such lawsuits are expensed in the period in which the costs are incurred.  Based upon currently available information, the Company does not believe it is reasonably possible that any such lawsuit or related lawsuits would be material to the Company’s results of operations or would have a material adverse effect on the Company’s financial position or liquidity.

Gain Contingency

On August 17, 2010, in a reinsurance dispute in New York state court captioned United States Fidelity & Guaranty Company v. American Re-Insurance Company, et al., the trial court granted summary judgment for United States Fidelity and Guaranty Company (USF&G), a subsidiary of the Company, and denied summary judgment for the reinsurers. The Court of Appeals largely affirmed the entry of summary judgment, but remanded two discrete issues for trial.

On November 7, 2016, the Company agreed to a settlement with one of the three defendants then remaining in this dispute. The Company received payment under the settlement in the fourth quarter of 2016 and, as a result, recognized a $126 million pre-tax ($82 million after-tax) gain in the fourth quarter, which was included in “other revenues” in the consolidated statement of income for the year ended December 31, 2016.  In connection with that settlement, the reinsurance recoverable balance related to this case was reduced from approximately $238 million to approximately $31 million in the Company’s consolidated balance sheet. At March 31, 2017, the claim related to the remaining defendants totaled $71 million, comprising the $31 million of reinsurance recoverable plus interest amounting to $40 million as of that date.  The interest was treated for accounting purposes as a gain contingency in accordance with FASB Topic 450, Contingencies, and accordingly was not recognized in the Company’s consolidated financial statements.

On May 1, 2017, the Company agreed to a settlement of this dispute with the two remaining defendants, along with the settlement of several other disputes with these same parties.  As a result of the settlement of all of these matters, the Company recorded an immaterial gain in “other revenues” in its consolidated statement of income for the three months ended June 30, 2017, and the reinsurance recoverable of $31 million in the Company’s balance sheet was fully satisfied.

Other Commitments and Guarantees

Commitments

Investment Commitments — The Company has unfunded commitments to private equity limited partnerships and real estate partnerships in which it invests.  These commitments totaled $1.58 billion and $1.60 billion at June 30, 2017 and December 31, 2016, respectively.

Guarantees

The maximum amount of the Company’s contingent obligation for indemnifications related to the sale of businesses that are quantifiable was $358 million at June 30, 2017, of which $2 million was recognized on the balance sheet at that date.

The maximum amount of the Company’s obligation for guarantees of certain investments and third-party loans related to certain investments that are quantifiable was $45 million at June 30, 2017, approximately $23 million of which is indemnified by a third party.  The maximum amount of the Company’s obligation related to the guarantee of certain insurance policy obligations of a former insurance subsidiary was $480 million at June 30, 2017, all of which is indemnified by a third party.  For more information regarding Company guarantees, see note 16 of notes to the consolidated financial statements in the Company’s 2016 Annual Report as updated by the Company’s Form 8-K filed on June 20, 2017.

Accounting Policies, Basis of Presentation [Policy Text Block]

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 Annual Report on Form 10-K for the year ended December 31, 2016 (the Company’s 2016 Annual Report) as updated by the Company’s Current Report on Form 8-K filed on June 20, 2017. The Form 8-K was filed to reclassify certain of the Company’s historical segment information to conform the presentation of such segment information to the manner in which the Company’s businesses have been managed beginning April 1, 2017 (as described in more detail below) and reflect the revised names and descriptions of certain businesses comprising these segments and other related changes.

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 March 13, 2017, the Company announced an agreement to acquire Simply Business, a leading digital provider of insurance policies to small businesses in the United Kingdom, for total consideration of approximately $490 million, which includes the repayment of debt and other obligations at the completion of the transaction.  The transaction is expected to close in the third quarter of 2017, subject to regulatory approvals and other customary closing conditions.  The Company will use a portion of the net proceeds from the issuance of senior notes in May 2017 (described in more detail in note 8) and internal resources to fund this transaction.

Accounting Policies, Adoption of Accounting Standards [Policy Text Block]

Adoption of Accounting Standards

Investments — Equity Method and Joint Ventures:  Simplifying the Transition to the Equity Method of Accounting

In March 2016, the Financial Accounting Standards Board (FASB) issued updated guidance that eliminates the requirement to retroactively apply the equity method of accounting when an investment that was previously accounted for using another method of accounting becomes qualified to apply the equity method due to an increase in the level of ownership interest or degree of influence.  If the investment was previously accounted for as an available-for-sale security, any related unrealized gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for the equity method is recognized through earnings.  The updated guidance was effective for reporting periods beginning after December 15, 2016, and was applied prospectively.  The adoption of this guidance did not have a material effect on the Company’s results of operations, financial position or liquidity.

Derivatives and Hedging:  Contingent Put and Call Options in Debt Instruments

In March 2016, the FASB issued updated guidance clarifying that when a call (put) option in a debt instrument can accelerate the repayment of principal on the debt instrument, a reporting entity does not need to assess whether the contingent event that triggers the ability to exercise the call (put) option is related to interest rates or credit risk in determining whether the option should be accounted for separately.  The updated guidance was effective for reporting periods beginning after December 15, 2016. The adoption of this guidance did not have a material effect on the Company’s results of operations, financial position or liquidity.

Compensation — Retirement Benefits: Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost

In March 2017, the FASB issued updated guidance to improve the presentation of net periodic pension cost and net periodic post retirement cost (net benefit costs). Net benefit costs comprise several components that reflect different aspects of an employer’s financial arrangements as well as the cost of benefits provided to employees.  The update requires that the employer service cost component be reported in the same lines as other employee compensation cost and that the other components (non-service costs) be presented separately from the service cost and outside of a subtotal of income from operations if one is presented.  The update also allows only the service cost component to be eligible for capitalization in assets when applicable.

The updated guidance is effective for reporting periods beginning after December 15, 2017. The update is to be applied retrospectively with respect to the presentation of service cost and non-service cost and prospectively with respect to applying the service cost only eligible for capitalization in assets guidance. Early adoption is permitted as of the first interim period of an annual period if an entity issues interim financial statements.

The Company adopted the updated guidance effective January 1, 2017. See note 12 which has been expanded to disclose the amount of service cost and non-service cost components of net periodic benefit cost and the line items in the consolidated statement of income in which such amounts are reported. The updated guidance with respect to only service costs being eligible for capitalization in assets was not applicable.

For information regarding accounting standards that the Company adopted during the years presented, see the “Adoption of Accounting Standards” section of note 1 of notes to the consolidated financial statements in the Company’s 2016 Annual Report as updated by the Company’s Current Report on Form 8-K filed on June 20, 2017.

Compensation — Stock Compensation: Scope of Modification Accounting

In May 2017, the FASB issued updated guidance related to a change to the terms or conditions (modification) of a share-based payment award.  The updated guidance provides that an entity should account for the effects of a modification unless the fair value and vesting conditions of the modified award and the classification of the modified award (equity or liability instrument) are the same as the original award immediately before the modification.

The updated guidance is effective for the quarter ending March 31, 2018.  The update is to be applied prospectively to an award modified on or after the adoption date. Early adoption is permitted in any interim periods for which financial statements have not yet been made available for issuance.

The Company adopted the updated guidance effective April 1, 2017. The adoption did not have an effect on the Company’s results of operations, financial position or liquidity.
