New York, January 22, 2015 — The Travelers Companies, Inc. today reported net income of $1.038 billion, or $3.11 per diluted share, for the quarter ended December 31, 2014, compared to net income of $988 million, or $2.70 per diluted share, in the prior year quarter. Operating income in the current quarter was $1.023 billion, or $3.07 per diluted share, compared to $981 million, or $2.68 per diluted share, in the prior year quarter. The increase in net and operating income primarily resulted from higher net favorable prior year reserve development and higher underlying underwriting gain (i.e., excluding net favorable prior year reserve development and catastrophe losses), partially offset by lower net investment income and an increase in other expense. Per diluted share amounts also benefited from the impact of share repurchases.

“Fourth quarter net income of $1.038 billion provided a strong finish to an excellent year financially, strategically, and operationally,” commented Jay Fishman, Chairman and Chief Executive Officer. “We achieved record levels of net income per diluted share for both the quarter and the full year of $3.11 and $10.70, respectively, benefitting from strong underwriting and investment results, as well as our ongoing strategy of returning excess capital to shareholders. For the full year, we achieved a return on equity of 14.6% and operating return on equity of 15.5%, bringing our average annual return on equity to 12.5% and average annual operating return on equity to 13.3% for the past decade.

“For the full year, all our business segments performed very well. Business and International Insurance profitability was very strong, with a combined ratio of 93.1% and operating income of over $2.3 billion. We remain very pleased with, and intend to continue, our proactive, account by account, class by class pricing strategy. Bond & Specialty Insurance had exceptional performance in 2014, with record operating income of $727 million. These results are a continuation of the superior, long-term performance this business has achieved while successfully navigating a very challenging and rapidly evolving economic environment. Results in Personal Insurance were strong, and we are especially pleased with the marketplace success of Quantum 2.0. We achieved net written premium growth in Auto in the second half of the year, as well as sequential increases in policies in force beginning in the third quarter. Importantly, loss indications for Quantum 2.0, while still preliminary, look to be in line with our expectations.

“We remain optimistic that we will continue to achieve superior returns over time across our business segments, and that, combined with our active capital management strategy, positions us to continue to deliver meaningful shareholder value.”

Consolidated Results

Fourth Quarter 2014 Results

(All comparisons vs. fourth quarter 2013, unless noted otherwise)

Net income of $1.038 billion after-tax increased $50 million, or 5%, primarily due to an increase in operating income. Operating income of $1.023 billion after-tax increased $42 million, or 4%, driven by a higher underwriting gain, partially offset by lower net investment income and an increase in other expense.

Underwriting results

·                  The combined ratio improved 2.7 points to 85.0% due to higher net favorable prior year reserve development (1.5 points), an improved underlying combined ratio (1.0 point), and lower catastrophe losses (0.2 points).

2

·                  The underlying combined ratio improved 1.0 point to 90.2% due to the benefits of earned pricing that exceeded loss cost trends.

·                  Net favorable prior year reserve development occurred in all segments. Catastrophe losses were primarily due to a wind and hail storm in the Midwest region of the United States, as well as increases in estimated losses related to certain wind and hail storms that occurred in the second quarter.

Net investment income of $637 million pre-tax ($513 million after-tax) decreased due to lower reinvestment rates in the fixed income portfolio and lower returns in the non-fixed income portfolio. Other expense of $65 million pre-tax increased primarily due to the benefit of several items that occurred in the prior year quarter.

Net written premiums of $5.836 billion increased 4% primarily driven by growth in domestic business insurance and the inclusion of Dominion.

Full Year 2014 Results

(All comparisons vs. full year 2013, unless noted otherwise)

Net income of $3.692 billion after-tax increased $19 million, or 1%, as an increase in operating income was mostly offset by a reduction in net realized investment gains. Prior year net realized investment gains included a significant gain related to a short position in U.S. Treasury futures contracts. Operating income of $3.641 billion after-tax increased $74 million, or 2%, primarily driven by a higher underwriting gain and higher net investment income, partially offset by an increase in other expense. Operating income in the prior year included the benefits of a favorable legal settlement of $91 million pre-tax ($59 million after-tax) and a favorable tax settlement of $63 million. Operating income in the current year included a $76 million pre-tax ($49 million after-tax) benefit recorded in the first quarter resulting from a reduction in the estimated liability for state assessments to be paid by the company related to workers’ compensation premiums.

Underwriting results

·                  The combined ratio improved 0.8 points to 89.0% due to an improved underlying combined ratio (1.0 points) and higher net favorable prior year reserve development (0.2 points), partially offset by higher catastrophe losses (0.4 points).

·                  The underlying combined ratio improved 1.0 point to 89.9% primarily due to the benefits of earned pricing that exceeded loss cost trends and the above mentioned reduction in the estimated liability for state assessments.

·                  Net favorable prior year reserve development occurred in all segments. Catastrophe losses were primarily due to wind, hail and winter storms in several regions in the United States.

Net investment income of $2.787 billion pre-tax ($2.216 billion after-tax) increased primarily due to strong private equity performance and higher real estate partnership returns, partially offset by lower reinvestment rates in the fixed income portfolio. Other expense of $255 million pre-tax increased primarily due to the inclusion in the prior year of the above mentioned favorable legal settlement, a gain from the sale of renewal rights related to the company’s National Flood Insurance Program (NFIP) and the benefit of several items that occurred in the prior year quarter.

Net written premiums of $23.904 billion increased 5% primarily due to the inclusion of Dominion and growth in domestic business insurance.

Business and International Insurance Segment Financial Results

Fourth Quarter 2014 Results

(All comparisons vs. fourth quarter 2013, unless noted otherwise)

Operating income of $630 million after-tax approximated the prior year quarter as a higher underwriting gain was offset primarily by lower net investment income.

Underwriting results

·                  The combined ratio improved 1.7 points to 89.8% due to lower catastrophe losses (1.2 points) and higher net favorable prior year reserve development (0.9 points), partially offset by a higher underlying combined ratio (0.4 points).

·                  The underlying combined ratio increased 0.4 points to 93.9% as the benefit of earned pricing that exceeded loss cost trends was more than offset by normal quarterly variability in loss activity and a modest increase in the expense ratio. The expense ratio in the prior year quarter benefited from a reduction in assessments from certain states.

·                  Net favorable prior year reserve development was primarily driven by better than expected loss experience in the general liability product line primarily related to excess coverages for accident years 2008 through 2012, reflecting more favorable legal and judicial environments than what the company previously expected, better than expected loss experience in the workers’ compensation product line across multiple accident years, and better than expected loss experience in the commercial auto product line for accident years 2011 and 2012.

4

Net written premiums of $3.575 billion increased 6% primarily driven by growth in domestic business insurance and the inclusion of Dominion. Domestic net written premiums of $3.031 billion increased 5% driven by continued positive renewal premium changes, increased new business volume and retention that remained strong and improved from recent quarters.

Full Year 2014 Results

(All comparisons vs. full year 2013, unless noted otherwise)

Operating income of $2.347 billion after-tax decreased $57 million, or 2%, as the pre-tax impact of higher net investment income and a higher underwriting gain was more than offset by a decline in other income. Operating income in the prior year included the benefits of a favorable legal settlement of $91 million pre-tax ($59 million after-tax) and a favorable tax settlement of $43 million. Operating income in the current year included a $76 million pre-tax ($49 million after-tax) benefit recorded in the first quarter resulting from a reduction in the estimated liability for state assessments to be paid by the company related to workers’ compensation premiums.

Underwriting results

·                  The combined ratio increased 0.3 points to 93.1% as the benefit of an improved underlying combined ratio (0.5 points) was more than offset by lower net favorable prior year reserve development (0.8 points).

·                  The underlying combined ratio improved 0.5 points to 92.8% due to the benefits of earned pricing that exceeded loss cost trends and the above mentioned reduction in the estimated liability for state assessments related to workers’ compensation premiums, partially offset by higher non-catastrophe weather-related losses and higher large loss activity.

·                  Net favorable prior year reserve development resulted from (i) better than expected loss experience in the general liability product line for accident years 2012 and prior as well as the property product line for accident years 2010 through 2013, (ii) a $162 million pre-tax benefit resulting from better than expected loss experience related to, and the commutation of reinsurance treaties associated with, a workers’ compensation reinsurance pool, partially offset by (iii) a $250 million pre-tax increase to asbestos reserves, (iv) an $87 million pre-tax increase to environmental reserves, (v) a $77 million pre-tax increase to unallocated loss adjusted expense (ULAE) reserves for interest awarded in a court decision received in the third quarter for which the settlement amount had been previously recognized and (vi) higher than expected loss experience related to the liability coverages in the commercial multi-peril product line for accident years 2010 through 2013.

Other income of $46 million pre-tax decreased primarily due to the inclusion in the prior year of the above mentioned favorable legal settlement.

Net written premiums of $14.636 billion increased 8% primarily driven by the inclusion of Dominion and growth in domestic business insurance. Domestic net written premiums of $12.515 billion increased 2% driven by continued positive renewal premium changes and higher retention levels.
