Branchville, NJ – July 29, 2015 – Selective Insurance Group, Inc. (NASDAQ: SIGI) today reported its financial results for the second quarter ended June 30, 2015. Net income per diluted share was $0.58, a 14% increase compared to $0.51 in 2014, and operating income¹ per diluted share grew 35% to $0.62, compared to $0.46 in 2014.

“Our results this quarter further demonstrate our continued focus on the value-enhancing initiatives underway and our ability to drive long-term profitable growth,” said Gregory E. Murphy, Chairman and Chief Executive Officer. “Our strong performance was driven by our efforts to balance rate and retention, implement claims and underwriting improvements across the organization while maintaining strong relationships with our distribution partners. The combination of our high-tech, high-touch capabilities continues to deliver success for our shareholders, distribution partners, customers and employees.”

Murphy continued, “For the second quarter, we generated a profitable 93.5% statutory combined ratio, or 88.6% excluding catastrophe losses. On the strength of our statutory underwriting results for the first six months, we are improving our full year ex-catastrophe statutory combined ratio target to 90% from 91%.

“Growth in the quarter was solid, as overall net premiums written increased 11% driven by Standard Commercial Lines new business production of $90 million, a 39% increase from a year ago, andoverall year-to-date renewal pure price increases of 3.8%. For 2015, we expect to achieve overall renewal pure price of just below 4%. The increase in new business this year reflects the capacity we have created through our agency management specialists and small business teams to grow share of wallet with our distribution partners. We are also adding agencies to have access to additional market share throughout our footprint,” Murphy concluded.

¹Operating income differs from net income by the exclusion of realized gains and losses on investments. It is used as an important financial measure by management, analysts, and investors, because the realization of investment gains and losses on sales in any given period is largely discretionary as to timing. In addition, these investment gains and losses, as well as other-than-temporary investment impairments that are charged to earnings, could distort the analysis of trends. Operating income is not intended as a substitute for net income prepared in accordance with U.S. generally accepted accounting principles (GAAP). A reconciliation of operating income to net income is provided in the Consolidated Financial Results table. Statutory data is prepared in accordance with statutory accounting rules as defined by the National Association of Insurance Commissioners Accounting Practices and Procedures Manual and, therefore, is not reconciled to GAAP.

Operating Highlights

Standard Commercial Lines

Standard Commercial Lines premiums were up 13% in the second quarter, reflecting renewal pure price increases of 3.0%, stable retention at 83%, and a 39% increase in new business to $90 million. The quarter’s statutory combined ratio improved by 5.4 points, largely due to earned rate continuing to exceed expected loss inflation, favorable prior year casualty reserve development of $21 million, or 5.6 points, and lower non-catastrophe weather-related losses.

Standard Personal Lines

Standard Personal Lines premiums decreased 3% in the quarter compared to a year ago, attributed to the ongoing strategic non-renewal of underperforming business and a decrease in new business. Retention remained stable at 82% and renewal pure price was 6.7%. The Selective Edge^TM product continues to be well received by Selective’s agents and the Company is optimistic about the improving take-up rate. We believe that this business will ultimately outperform the non-Edge business.

The statutory combined ratio in Standard Personal Lines was 105.4%, which included 11.5 points of catastrophe losses. There was no prior year casualty reserve development this quarter in Standard Personal Lines, although there was favorable prior year casualty reserve development of $2 million, or 2.7 combined ratio points, in the second quarter of 2014.

Excess and Surplus Lines

Growth in the Company’s Excess and Surplus lines business this quarter was very robust with a 20% increase in net premiums written, largely attributable to new business growth of 36%.

Investment Income

After-tax investment income in the second quarter was $25 million, down 10% compared to a year ago. The decline was largely driven by lower interest income from the fixed income portfolio and lower returns from the alternative portfolio, which continues to be impacted by the portfolio’s exposure to energy-exposed limited partnerships. The decline in alternative investment income and the continued low interest rate environment reduced after-tax portfolio yields to 1.9% from 2.3% a year ago. After-tax new money yields averaged 1.5% in the quarter.
