New York, October 20, 2015 — The Travelers Companies, Inc. today reported net income of $928 million, or $2.97 per diluted share, for the quarter ended September 30, 2015, compared to net income of $919 million, or $2.69 per diluted share, in the prior year quarter. Operating income in the current quarter was $918 million, or $2.93 per diluted share, compared to $893 million, or $2.61 per diluted share, in the prior year quarter. The increase in net and operating income primarily resulted from higher underlying underwriting gains (i.e., excluding net favorable prior year reserve development and catastrophe losses) and higher net favorable prior year reserve development, partially offset by lower net investment income. Per diluted share amounts also benefited from the impact of share repurchases.

“We are very pleased to report third quarter operating income of $918 million and operating return on equity of 16.2%,” commented Jay Fishman, Chairman and Chief Executive Officer. “At 86.9%, our combined ratio reflected very strong performance across all of our business segments. Our investment portfolio continued to deliver solid returns in the continuing low interest rate environment. We also returned $939 million in capital to shareholders in the quarter, including $750 million in share repurchases, bringing the total capital returned to shareholders year to date to over $2.7 billion.

“Each of our business segments performed well in the quarter. In Business and International Insurance, the combined ratio improved to 92.2%, and retention remained at historically high levels. Bond & Specialty Insurance delivered very strong results, with a 57.1% combined ratio, as well as higher retention and new business volume in Management Liability. Personal Insurance also posted very strong results, delivering a combined ratio of 85.1% and net written premium growth of 6%. Notably, Agency Auto achieved growth in both net written premiums and policies in force of 10% and 6%, respectively.

“These results continue to build on our record of delivering superior returns over time. Since January 1, 2005, we have produced an average annual operating return on equity of 13.4%. With our meaningful competitive advantages, as well as our commitment to our proven investment and capital management strategies, we remain well positioned to continue to deliver on our long-term financial objectives.”

Consolidated Results

Third Quarter 2015 Results

(All comparisons vs. third quarter 2014, unless noted otherwise)

Net income of $928 million after-tax and operating income of $918 million after-tax increased $9 million and $25 million, respectively, primarily driven by a higher underlying underwriting gain and higher net favorable prior year reserve development, partially offset by lower net investment income.

2

Underwriting results

·                  The combined ratio improved 3.1 points to 86.9% due to a lower underlying combined ratio (1.7 points) and higher net favorable prior year reserve development (1.4 points).

·                  The underlying combined ratio remained strong and improved 1.7 points to 88.8%, primarily driven by lower non-catastrophe weather-related losses in Business and International Insurance.

·                  Net favorable prior year reserve development occurred in all segments. Catastrophe losses primarily resulted from wildfires in California, as well as wind and hail storms in the Midwest region of the United States.

Net investment income of $614 million pre-tax ($484 million after-tax) decreased primarily due to lower returns in both the non-fixed income and fixed income portfolios. Non-fixed income returns remained strong, but declined as compared to a particularly high level in the prior year quarter. Fixed income returns declined primarily due to lower reinvestment rates and a modestly lower amount of fixed income investments that were impacted by the Company’s $579 million payment in the first quarter of 2015 related to the settlement of the Asbestos Direct Action Litigation.

Net written premiums of $6.191 billion increased 3% from the prior year quarter, benefiting from strong retention and positive renewal premium changes in each business segment, as well as higher new business volume in Personal Insurance. Net written premiums also benefited from the impact of changes in the timing and structure of certain of the Company’s reinsurance treaties that occurred in prior quarters, partially offset by the impact of changes in foreign currency exchange rates.

Year-to-Date 2015 Results

(All comparisons vs. year-to-date 2014, unless noted otherwise)

Net income of $2.573 billion after-tax and operating income of $2.551 billion after-tax decreased $81 million and $67 million, respectively, primarily driven by lower net investment income, partially offset by a higher underwriting gain. The increase in the underwriting gain was primarily due to lower catastrophe losses, higher net favorable prior year reserve development and a $32 million benefit from the resolution of prior year tax matters. The underwriting gain in the prior year period benefited from a $49 million after-tax ($76 million pre-tax) reduction in the estimated liability for state assessments to be paid by the Company related to workers’ compensation premiums due to a change in state law.

Underwriting results

·                  The combined ratio improved 1.4 points to 88.9% due to lower catastrophe losses (1.1 points) and higher net favorable prior year reserve development (0.3 points).

·                  The underlying combined ratio of 89.9% remained strong and was comparable to the prior year period.

·                  Net favorable prior year reserve development occurred in all segments. Catastrophe losses included the third quarter 2015 events discussed above, as well as wind and hail storms in several regions of the United States in the second quarter of 2015 and a winter storm in the eastern United States in the first quarter of 2015.

Net investment income of $1.838 billion pre-tax ($1.465 billion after-tax) decreased primarily due to the same factors discussed above for the third quarter of 2015.

Net written premiums of $18.257 billion increased 1% from the prior year period, benefiting from strong retention and positive renewal premium changes in each business segment, as well as higher new business volume in Personal Insurance, partially offset by the impact of changes in foreign currency exchange rates.

3

Shareholders’ Equity

Shareholders’ equity of $24.033 billion decreased 3% from year-end 2014 due to a reduction in after-tax net unrealized investment gains and an increase in after-tax unrealized foreign currency translation losses. After-tax net unrealized investment gains were $1.414 billion, compared to $1.966 billion at year-end 2014. Book value per share of $79.00 and adjusted book value per share of $74.35 increased 2% and 5%, respectively, from year-end 2014.

The Company repurchased 7.3 million shares during the third quarter and 21.5 million shares year-to-date at a total cost of $750 million and $2.223 billion, respectively, leaving $4.334 billion of remaining capacity under its existing share repurchase authorization at the end of the quarter. Also as of the end of the quarter, statutory capital and surplus was $20.822 billion and the ratio of debt-to-capital (excluding after-tax net unrealized investment gains) was 23.0%, comfortably within the Company’s target range of 15% to 25%.

The Board of Directors today declared a quarterly dividend of $0.61 per share. This dividend is payable on December 31, 2015, to shareholders of record as of the close of business on December 10, 2015.

Business and International Insurance Segment Financial Results

Third Quarter 2015 Results

(All comparisons vs. third quarter 2014, unless noted otherwise)

Business and International Insurance had another strong quarter with operating income of $546 million after-tax and a combined ratio of 92.2%. Operating income decreased $6 million due to lower net investment income, mostly offset by a higher underlying underwriting gain and higher net favorable prior year reserve development.

4

Underwriting results

·                  The combined ratio improved 3.0 points to 92.2%, due to a lower underlying combined ratio (2.4 points) and higher net favorable prior year reserve development (0.8 points), partially offset by higher catastrophe losses (0.2 points).

·                  The underlying combined ratio remained strong and improved 2.4 points to 92.5% driven by lower non-catastrophe weather-related losses.

·                  Net favorable prior year reserve development primarily resulted from (i) better than expected loss experience for the property product line related to catastrophe losses for accident years 2011, 2012 and 2014 and non-catastrophe losses for accident years 2013 and 2014, (ii) better than expected loss experience in the general liability product line for both primary and excess coverages for accident years 2005 through 2013, reflecting a more favorable legal environment than the Company previously expected, (iii) better than expected loss experience in the workers’ compensation product line for accident years 2005 and prior and (iv) better than expected loss experience in the Company’s operations in Canada, partially offset by (v) a $224 million pre-tax increase to asbestos reserves.

·                  The asbestos reserve strengthening, which resulted from our annual in-depth asbestos claim review that was completed in the third quarter, was driven by increases in the Company’s estimate for projected settlement and defense costs related to a broad number of policyholders. The increase in the estimate of projected settlement and defense costs resulted from recent payment trends that continue to be higher than previously anticipated. While the overall view of the underlying asbestos environment is essentially unchanged from recent periods, there remains a high degree of uncertainty with respect to future exposure to asbestos claims.

Net written premiums increased 1% to $3.590 billion. Domestic net written premiums increased 4% driven by an increase in retention rates, positive renewal premium changes and the impact of changes in the timing and structure of certain of the Company’s reinsurance treaties that occurred in prior quarters. International net written premiums decreased 19% primarily due to the impact of changes in foreign currency exchange rates and lower business volume in the Company’s operations at Lloyd’s.

Year-to-Date 2015 Results

(All comparisons vs. year-to-date 2014, unless noted otherwise)

Business and International Insurance operating income of $1.604 billion after-tax was strong and decreased $113 million, primarily due to lower net investment income, partially offset by a higher underwriting gain. The underwriting gain increased due to lower catastrophe losses, higher net favorable prior year reserve development and a $12 million benefit from the resolution of prior year tax matters. The underwriting gain in the prior year period benefited from a $49 million after-tax ($76 million pre-tax) reduction in the estimated liability for state assessments to be paid by the Company related to workers’ compensation premiums due to a change in state law.

Underwriting results

·                  The combined ratio improved 1.3 points to 92.9%, due to lower catastrophe losses (1.1 points) and higher net favorable prior year reserve development (0.6 points), partially offset by a higher underlying combined ratio (0.4 points).

·                  The underlying combined ratio remained strong at 92.8%, an increase of 0.4 points.

·                  Net favorable prior year reserve development primarily resulted from (i) better than expected loss experience in the general liability product line, for both primary and excess coverages for accident years 2005 through 2013, reflecting a more favorable legal environment than the Company previously expected, (ii) better than expected loss experience for the property product line related to catastrophe losses for accident years 2011, 2012 and 2014 and non-catastrophe losses for accident years 2013 and 2014, (iii) better than expected loss experience in the workers’ compensation line of business for accident years 2006 and prior and (iv) better than expected loss experience in the Company’s operations at Lloyd’s and in Canada, partially offset by (v) a $224 million pre-tax increase to asbestos reserves and (vi) a $72 million pre-tax increase to environmental reserves.

5

Net written premiums of $11.066 billion were comparable to the prior year period. Domestic net written premiums increased 2% driven by an increase in retention rates, positive renewal premium changes and an increase in new business. International net written premiums decreased 14% primarily due to the impact of changes in foreign currency exchange rates.

Bond & Specialty Insurance Segment Financial Results

Third Quarter 2015 Results

(All comparisons vs. third quarter 2014, unless noted otherwise)

Bond & Specialty Insurance had another excellent quarter with operating income of $196 million after-tax and a combined ratio of 57.1%. Operating income increased $31 million due to a higher underlying underwriting gain and higher net favorable prior year reserve development.

Underwriting results

·                  The combined ratio was very strong at 57.1% and improved 9.8 points, primarily due to a lower underlying combined ratio (5.6 pts) and higher net favorable prior year reserve development (4.1 points).

·                  The underlying combined ratio was very strong at 76.1% and improved 5.6 points primarily due to a re-estimation of current accident year losses in certain management liability businesses and the impact of certain customer-related intangible assets which became fully amortized during the second quarter of 2015.

·                  Net favorable prior year reserve development primarily resulted from better than expected loss experience in the contract surety and fidelity product lines for accident years 2008 through 2013.

Bond & Specialty Insurance net written premiums increased slightly to $565 million driven by higher volume in Surety.

6

·                  The underlying combined ratio remained strong at 85.2%, an increase of 1.2 points, primarily due to higher non-weather-related losses in Homeowners & Other, partially offset by a lower expense ratio.

(All comparisons vs. year-to-date 2014, unless noted otherwise)

Personal Insurance performed well in the period as operating income of $667 million after-tax increased $85 million.

Underwriting results

·                  The combined ratio improved 3.2 points to 86.6%, due to higher net favorable prior year reserve development (1.6 points), lower catastrophe losses (1.5 points) and a lower underlying combined ratio (0.1 points).

·                  The underlying combined ratio remained strong at 87.0%.

·                  Net favorable prior year reserve development primarily resulted from (i) better than expected loss experience in the homeowners and other product line for liability coverages for accident years 2011 through 2014, for non-catastrophe weather-related losses for accident years 2013 and 2014, and for non-weather-related losses for accident year 2014 and (ii) better than expected loss experience in the automobile product line for liability coverages for accident years 2010 through 2014.

Other income of $33 million pre-tax decreased primarily due to the inclusion in the prior year period of revenues associated with the runoff of the Company’s National Flood Insurance Program which was sold on a renewal rights basis in 2013.

Personal Insurance net written premiums of $5.614 billion increased 3%. Agency Automobile net written premiums increased 7% due to higher new business volume, driven by Quantum 2.0, while Agency Homeowners & Other net written premiums decreased 1%.
