(1) As a result of recent SEC insurance industry guidance concerning terminology, what we previously referred to as “operating income (loss)” in our public disclosures we now refer to as “core income (loss).” Additionally, the related financial measures of “operating income (loss) per share” and “operating return on equity” were changed accordingly. There were no changes in the calculation of these amounts.

New York, April 20, 2017 — The Travelers Companies, Inc. today reported net income of $617 million, or $2.17 per diluted share, for the quarter ended March 31, 2017, compared to $691 million, or $2.30 per diluted share, in the prior year quarter. Core income in the current quarter was $614 million, or $2.16 per diluted share, compared to $698 million, or $2.33 per diluted share, in the prior year quarter. Net and core income in both the current and prior year quarters were impacted by significant catastrophe losses of $226 million after-tax ($347 million pre-tax) and $207 million after-tax ($318 million pre-tax), respectively. The decreases from the prior year quarter were primarily driven by lower net favorable prior year reserve development that included a $51 million after-tax ($62 million pre-tax) impact from the UK Ministry of Justice’s recent “Ogden” discount rate adjustment, a lower underlying underwriting gain (i.e., excluding net favorable prior year reserve development and catastrophe losses) and higher catastrophe losses, partially offset by higher net investment income. The current quarter benefited from a $39 million resolution of prior year income tax matters, while the prior year quarter benefited modestly from the favorable settlement of a claims-related legal matter. Per diluted share amounts benefited from the impact of share repurchases.

“Core income of $614 million and core return on equity of 10.8% reflected unusually high first quarter catastrophe losses that arose from a record number of tornado and hail events,” commented Alan Schnitzer, Chief Executive Officer. “We were pleased with our underlying underwriting results and that loss trends were stable and consistent with our expectations for all of our businesses, including personal auto. We were also pleased with our investment results this quarter. Net investment income, which benefited from strong private equity returns, increased 9% on an after-tax basis over the prior year quarter. Our results enabled us to return $476 million to shareholders, including $286 million in share repurchases, while adding additional holding company liquidity to build flexibility for the funding of the Simply Business acquisition. In recognition of our strong financial position, the Board of Directors declared a 7.5% increase in our quarterly cash dividend to $0.72 per share and authorized an additional $5.0 billion of share repurchases.

“Net written premiums grew 5% to a record level this quarter, with each business segment contributing to the growth. In our commercial businesses, the markets in which we operate remained stable. We continued to achieve historically high levels of retention, and renewal rate change remained positive and improved modestly from recent quarters. The improvement in renewal rate change reflects our focused efforts to seek rate selectively and thoughtfully on an account-by-account or class-by-class basis. While we always actively seek new business opportunities, new business was down modestly from the prior year quarter as we continued to maintain our disciplined approach to underwriting. In Personal Insurance, net written premiums increased by 12%, including the impact of auto rate increases that were consistent with our plans to improve profitability. We were also pleased that we were able to continue the momentum in growing our very profitable homeowners business.

“With technology and innovation driving customer preferences and expectations, advancing our digital agenda to best serve customers and our distribution partners, now and in the future, is a key strategic priority. To that end, during the quarter we announced an agreement to purchase Simply Business, a leading digital provider of insurance to small businesses in the United Kingdom. Our investment in Simply Business will accelerate our digital agenda, building on the competitive advantages that have enabled us to deliver industry-leading returns.”

Consolidated Results

First Quarter 2017 Results

(All comparisons vs. first quarter 2016, unless noted otherwise)

Net income of $617 million after-tax decreased $74 million due to lower core income, slightly offset by net realized investment gains in the current quarter as compared to net realized investment losses in the prior year quarter. Core income of $614 million after-tax decreased $84 million, primarily driven by lower net favorable prior year reserve development that included a $51 million after-tax ($62 million pre-tax) impact from the recent Ogden discount rate adjustment, a lower underlying underwriting gain as explained below and higher catastrophe losses, partially offset by higher net investment income. The current quarter benefited from a $39 million resolution of prior year income tax matters, while the prior year quarter benefited modestly from the favorable settlement of a claims-related legal matter.

2

Underwriting results

·                  The combined ratio of 96.0%, which was impacted by significant catastrophe losses as was the prior year quarter, increased 3.7 points due to lower net favorable prior year reserve development (1.7 points), a higher underlying combined ratio (1.7 points) and higher catastrophe losses (0.3 points).

·                  The underlying combined ratio of 91.7% increased 1.7 points, primarily driven by normal quarterly variability in non-catastrophe weather-related losses and other loss activity and the timing impact of higher loss estimates in personal automobile bodily injury liability coverages that were consistent with the higher loss trends we recognized in the last half of 2016.

·                  Net favorable prior year reserve development occurred in Business and International Insurance and Bond & Specialty Insurance and included the recent Ogden discount rate adjustment. Catastrophe losses in the first quarter of 2017 primarily resulted from wind and hail storms in several regions of the United States, as well as a winter storm in the eastern United States.

Net investment income of $610 million pre-tax ($480 million after-tax) increased 9% after-tax driven by higher private equity returns, partially offset by fixed income returns that declined in line with our expectations due to lower reinvestment rates available in the market.

Other income/(expense) in the prior year quarter included proceeds from the favorable settlement of a claims-related legal matter.

Net written premiums of $6.495 billion, a record level, increased 5%, reflecting growth in all segments.

Shareholders’ Equity

Shareholders’ equity of $23.612 billion increased 2% from year-end 2016. After-tax net unrealized investment gains were $823 million ($1.255 billion pre-tax) compared to $730 million after-tax ($1.112 billion pre-tax) at year-end 2016. Book value per share of $84.51 and adjusted book value per share of $81.56 increased 2% and 1%, respectively, from year-end 2016.

The Company repurchased 2.4 million shares during the first quarter at an average price of $120.68 per share for a total cost of $286 million, which was reduced from recent quarters to provide financing flexibility for the pending acquisition of Simply Business. At the end of first quarter 2017, statutory capital and surplus was $20.617 billion and the ratio of debt-to-capital was 21.4%. The ratio of debt-to-capital excluding after-tax net unrealized investment gains was 22.0%, well within the Company’s target range of 15% to 25%.

The Board of Directors today declared a quarterly dividend of $0.72 per share, an increase of 7.5%. This dividend is payable on June 30, 2017, to shareholders of record as of the close of business on June 9, 2017. The Board of Directors also authorized an additional $5.0 billion of share repurchases. This amount is in addition to the $709 million that remained from previous authorizations as of March 31, 2017. This authorization does not have a stated expiration date. The timing and actual number of shares to be repurchased will depend on a variety of factors, including the factors described below in the Forward-Looking Statement section.

Business and International Insurance Segment Financial Results

(2) As a result of recent SEC insurance industry guidance concerning terminology, what we previously referred to as “operating income (loss)” in our public disclosures when referring to business segment results is now labeled “segment income (loss).” There were no changes in the calculation of these amounts.

First Quarter 2017 Results

(All comparisons vs. first quarter 2016, unless noted otherwise)

Segment income for Business and International Insurance was $468 million after-tax, a decrease of $8 million, primarily driven by a decrease in net favorable prior year reserve development due to a $51 million after-tax ($62 million pre-tax) increase in reserves related to the recent Ogden discount rate adjustment, a lower underlying underwriting gain as explained below, partially offset by higher net investment income and modestly lower catastrophe losses as compared to a particularly high level of catastrophe losses in the prior year quarter. The current quarter benefited from a $15 million resolution of prior year income tax matters, while the prior year quarter benefited modestly from the favorable settlement of a claims-related legal matter.

Underwriting results

·                  The combined ratio of 96.3% increased 1.5 points due to a higher underlying combined ratio (1.2 points) and lower net favorable prior year reserve development (0.7 points), partially offset by lower catastrophe losses (0.4 points).

·                  The underlying combined ratio of 94.5% increased 1.2 points, primarily driven by normal quarterly variability in non-catastrophe weather-related losses and other loss activity and loss cost trends that modestly exceeded earned pricing.

·                  Net favorable prior year reserve development primarily resulted from better-than-expected loss experience in the Company’s domestic operations in (i) the workers’ compensation product line for multiple accident years and (ii) the general liability product line for both primary and excess coverages for accident years 2009 and prior as well as accident year 2014, partially offset by (iii) net unfavorable prior year reserve development in the Company’s international operations in Europe due to the recent Ogden discount rate adjustment applied to lump sum bodily injury payouts.

Other income in the prior year quarter included proceeds from the favorable settlement of a claims-related legal matter.

Net written premiums of $4.027 billion, a record level, increased 3%, benefiting from continued strong retention and improved renewal premium changes.

First Quarter 2017 Results

(All comparisons vs. first quarter 2016, unless noted otherwise)

Underwriting results

·                  The combined ratio of 79.3% increased 10.0 points due to lower net favorable prior year reserve development.

·                  The underlying combined ratio remained very strong at 81.1%.

·                  Net favorable prior year reserve development resulted from better-than-expected loss experience in the fidelity and surety product line for accident year 2014.

Personal Insurance Segment Financial Results

(1) Represents business sold through agents, brokers and other intermediaries, and excludes direct to consumer.

First Quarter 2017 Results

(All comparisons vs. first quarter 2016, unless noted otherwise)

Segment income for Personal Insurance was $79 million after-tax, a decrease of $60 million, primarily driven by a lower underlying underwriting gain as explained below, higher catastrophe losses and no net prior year reserve development compared to net favorable prior year reserve development in the prior year quarter, partially offset by higher net investment income. The current quarter benefited from a $7 million resolution of prior year income tax matters.

Underwriting results

·                  The combined ratio of 99.9% increased 6.2 points due to a higher underlying combined ratio (3.4 points), no net prior year reserve development compared to net favorable prior year reserve development in the prior year quarter (1.4 points) and higher catastrophe losses (1.4 points).

·                  The underlying combined ratio of 89.5% increased 3.4 points, primarily driven by the timing impact of higher loss estimates in personal automobile bodily injury liability coverages that were consistent with the higher loss trends we recognized in the last half of 2016, the tenure impact of higher levels of new business in auto and normal quarterly variability in non-catastrophe weather-related losses and other loss activity, partially offset by a lower expense ratio.

Net written premiums of $1.964 billion increased 12%. Agency Automobile net written premiums growth of 17% benefited from the impact of auto rate increases that were consistent with our plans to improve profitability and an increase in policies in force of 12% from the prior year quarter.

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);

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.

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

7

·                  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 it 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 we are exposed to credit risk related to our 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 we have 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;

·                  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;

8

·                  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.

Our forward-looking statements speak only as of the date of this press release or as of the date they are made, and we undertake no obligation to update forward-looking statements. For a more detailed discussion of these factors, see the information under the captions “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our most recent annual report on Form 10-K filed with the Securities and Exchange Commission (SEC) on February 16, 2017, as updated by our periodic filings with the SEC.

GLOSSARY OF FINANCIAL MEASURES AND RECONCILIATIONS OF GAAP MEASURES TO NON-GAAP MEASURES

The following measures are used by the Company’s management to evaluate financial performance against historical results and establish targets on a consolidated basis. In some cases, these measures are considered non-GAAP financial measures under applicable SEC rules because they are not displayed as separate line items in the consolidated financial statements or are not required to be disclosed in the notes to financial statements or, in some cases, include or exclude certain items not ordinarily included or excluded in the most comparable GAAP financial measure. Reconciliations of non-GAAP measures to their most directly comparable GAAP measures also follow.

In the opinion of the Company’s management, a discussion of these measures provides investors, financial analysts, rating agencies and other financial statement users with a better understanding of the significant factors that comprise the Company’s periodic results of operations and how management evaluates the Company’s financial performance.  Internally, the Company’s management uses these measures to evaluate performance against historical results, to establish financial targets on a consolidated basis and for other reasons, which are discussed below.

Some of these measures exclude net realized investment gains (losses), net of tax, and/or net unrealized investment gains (losses), net of tax, which can be significantly impacted by both discretionary and other economic factors and are not necessarily indicative of operating trends.

Other companies may calculate these measures differently, and, therefore, their measures may not be comparable to those used by the Company’s management.

RECONCILIATION OF NET INCOME TO CORE INCOME AND CERTAIN OTHER NON-GAAP MEASURES

Core income (loss) is net income (loss) excluding the after-tax impact of net realized investment gains (losses), discontinued operations and cumulative effect of changes in accounting principles when applicable. Segment income (loss) is comparable to core income (loss) on a segment basis. Management uses segment income (loss) to analyze each segment’s performance and as a tool in making business decisions. Financial statement users also consider core income when analyzing the results and trends of insurance companies. Core income (loss) per share is core income (loss) on a per common share basis.

Reconciliation of Segment Income to Total Core Income

RECONCILIATION OF SHAREHOLDERS’ EQUITY TO ADJUSTED SHAREHOLDERS’ EQUITY AND CALCULATION OF RETURN ON EQUITY AND CORE RETURN ON EQUITY

Adjusted shareholders’ equity is shareholders’ equity excluding net unrealized investment gains (losses), net of tax, net realized investment gains (losses), net of tax, for the period presented, preferred stock and discontinued operations.

10

Reconciliation of Shareholders’ Equity to Adjusted Shareholders’ Equity

Return on equity is the ratio of annualized net income less preferred dividends to average shareholders’ equity for the periods presented. Core return on equity is the ratio of annualized core income less preferred dividends to adjusted average shareholders’ equity for the periods presented. In the opinion of the Company’s management, these are important indicators of how well management creates value for its shareholders through its operating activities and its capital management.

Average shareholders’ equity is (a) the sum of total shareholders’ equity excluding preferred stock at the beginning and end of each of the quarters for the period presented divided by (b) the number of quarters in the period presented times two.

Adjusted average shareholders’ equity is (a) the sum of adjusted shareholders’ equity at the beginning and end of each of the quarters for the period presented divided by (b) the number of quarters in the period presented times two.

Calculation of Return on Equity and Core Return on Equity
