New York, October 21, 2014 — The Travelers Companies, Inc. today reported net income of $919 million, or $2.69 per diluted share, for the quarter ended September 30, 2014, compared to net income of $864 million, or $2.30 per diluted share, in the prior year quarter. Operating income in the current quarter was $893 million, or $2.61 per diluted share, compared to $883 million, or $2.35 per diluted share, in the prior year quarter. The increase in net and operating income compared to the prior year quarter primarily resulted from higher net investment income and lower catastrophe losses, partially offset by lower net favorable prior year reserve development and a slightly lower underlying underwriting gain (i.e., excluding net favorable prior year reserve development and catastrophe losses), which was impacted by higher non-catastrophe weather-related losses. Net income also benefited from higher net realized investment gains while per diluted share amounts also benefited from the impact of share repurchases.

“We are very pleased with our results this quarter,” commented Jay Fishman, Chairman and Chief Executive Officer.  “Our results were driven by strong underwriting performance across all of our business segments, as reflected in our consolidated combined ratio of 90.0%, and higher investment returns driven by private equity performance. Our return on equity and per share results continue to benefit meaningfully from our ongoing strategy of returning excess capital to shareholders. Year-to-date, total capital returned to shareholders was almost $2.9 billion, including over $2.3 billion in share repurchases and $553 million in dividends.

“In addition to these strong financial results, we were also very pleased with our production metrics this quarter. Within Business and International Insurance, once again, we improved retention in our domestic businesses from already strong levels in recent quarters, while continuing to achieve meaningful rate and exposure increases. Bond & Specialty Insurance improved profitability from already high levels, and continued to achieve positive renewal premium change while maintaining strong retention. In Personal Insurance, Auto net written premiums were up 3% from the prior year quarter and policies in force were up 1% from the most recent quarter as a result of the very successful introduction of Quantum 2.0 beginning last fall.

“As we continue to face persistently low interest rates and uncertain weather patterns, we remain focused on delivering superior profitability and returns on equity. Consequently, we remain committed to our highly segmented pricing and underwriting strategies, executing on an account by account or class by class basis.”

Consolidated Results

Third Quarter 2014 Results

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

Net income of $919 million after-tax increased $55 million, or 6%, due to an increase in both net realized investment gains and operating income. Current period net realized investment gains resulted from the sale of substantially all of one of the company’s real estate joint venture investments. Operating income of $893 million after-tax increased $10 million, or 1%, primarily driven by higher net investment income and a continued strong, but lower, underwriting gain.

Underwriting results

·                  The combined ratio increased 1.1 points to 90.0% as the benefit of lower catastrophe losses (0.3 points) was more than offset by lower net favorable prior year reserve development (0.9 points) and a higher underlying combined ratio (0.5 points).

2

·                  The underlying combined ratio increased 0.5 points to 90.5% as the benefit of earned pricing that exceeded loss cost trends was more than offset by higher non-catastrophe weather-related losses.

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

Net investment income of $568 million after-tax ($719 million pre-tax) increased due to strong private equity performance, partially offset by lower reinvestment rates in the fixed income portfolio.

Net written premiums of $6.033 billion increased 6% primarily due to the inclusion of Dominion and domestic business insurance growth within Business and International Insurance.

Year-to-Date 2014 Results

(All comparisons vs. year-to-date 2013, unless noted otherwise)

Net income of $2.654 billion after-tax decreased $31 million, or 1%, due to lower net realized investment gains. Prior period net realized investment gains related to a short position in U.S. Treasury futures contracts. Operating income of $2.618 billion after-tax increased $32 million, or 1%, driven by higher net investment income and a higher underwriting gain, partially offset by a decline in other income due to the inclusion of a benefit in the prior year period of a $91 million pre-tax favorable legal settlement, as well as the inclusion in the prior year period of a $63 million benefit from a favorable tax settlement. The current period operating income included a $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 0.3 points to 90.3% due to an improved underlying combined ratio (0.9 points), partially offset by higher catastrophe losses (0.5 points) and lower net favorable prior year reserve development (0.1 points).

·                  The underlying combined ratio improved 0.9 points to 89.9% as the benefits of earned pricing that exceeded loss cost trends and an improved expense ratio were partially offset by higher non-catastrophe weather-related losses. The expense ratio benefited from 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 $1.703 billion after-tax ($2.150 billion pre-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.

Net written premiums of $18.068 billion increased 5% primarily due to the inclusion of Dominion and domestic business insurance growth within Business and International Insurance.

Shareholders’ Equity

Shareholders’equity of $25.321 billion decreased 1% and increased 2%, respectively, from the end of second quarter 2014 and year-end 2013.

Third Quarter 2014 Results

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

Operating income of $552 million after-tax decreased $14 million, or 2%, as higher net investment income was more than offset by a lower underwriting gain.

Underwriting results

·                  The combined ratio increased 2.5 points to 95.2% as the benefit of lower catastrophe losses (0.9 points) was more than offset by a higher underlying combined ratio (1.7 points) and lower net favorable prior year reserve development (1.7 points).

·                  The underlying combined ratio increased 1.7 points to 94.9% as the benefit of earned pricing that exceeded loss cost trends was more than offset by higher non-catastrophe weather-related losses.

·                  Net favorable prior year reserve development resulted from (i) a $162 million pre-tax benefit related to better than expected loss experience related to, and the commutation of reinsurance treaties associated with, a workers’ compensation reinsurance pool for accident years 1996 and prior and (ii) better than expected loss experience in the general liability product line for accident years 2009 through 2012 as well as the property product line for accident years 2012 and 2013, partially offset by (iii) a $250 million pre-tax increase to asbestos reserves, and (iv) a $77 million pre-tax increase to unallocated loss adjusted expense (ULAE) reserves for the accrual of interest resulting from a court decision received in the third quarter, for which the associated settlement amount had been previously included in our 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 were 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 from asbestos claims.

Net written premiums of $3.560 billion increased 10% primarily driven by the inclusion of Dominion. Domestic net written premiums of $3.079 billion increased 2% driven by continued positive renewal premium changes. Retention remained strong and improved from recent quarters.
