First Quarter 2012 Earnings

Branchville, NJ – April 25, 2012 – Selective Insurance Group, Inc. (NASDAQ: SIGI) today reported its financial results for the first quarter ended March 31, 2012.  Net income per diluted share was $0.33 and operating income1 was $0.28 per diluted share.

“Overall, we are pleased with our first quarter performance and the progress we continue to drive throughout the organization,” said Chairman, President and Chief Executive Officer Gregory E. Murphy.  “There is clear evidence of more rational commercial lines pricing, terms and conditions by almost all competitors who are now seeking increases on renewal business.  Our nimbleness, combined with pricing sophistication and outstanding agency relationships, provides us with high-quality growth and underwriting opportunities.

“For the quarter, our statutory combined ratio was a profitable 99.1% with both personal and commercial lines achieving combined ratios under 100%,” said Murphy.  “Commercial lines price was up 5.1% for the quarter, with March generating a 6% increase, and commercial lines retention for the quarter improved 3 points to a very strong 83%.

“Overall net premiums written (NPW) grew 16% in the quarter compared to 2011,” continued Murphy.  “Excess and surplus (E&S) lines contributed 7 points, with the remainder attributable to renewal price increases in personal and commercial lines that were over 5%; direct new business that rose 36% or $22 million; and overall retention that improved 2 points to a solid 84%.

“Our personal lines operations continue to grow due to filed rate increases that were effective for the quarter that averaged 5.9%, while retention improved 1 point from a year ago to 87%,” said Murphy.  “The personal lines statutory combined ratio for the quarter was profitable at 97.7%.”

Selective’s first quarter 2012 highlights compared to first quarter 2011:

-   Net income was $18.1 million, or $0.33 per diluted share, compared to net income of $20.5 million, or $0.37 per diluted share;

-   Operating income1 was $15.3 million, or $0.28 per diluted share, compared to operating income1 of $16.8 million, or $0.30 per diluted share;

-   Combined ratio: GAAP: 100.4% compared to 103.6%; Statutory: 99.1% compared to 102.6%;

Factors that could cause our actual results to differ materially from those projected, forecasted or estimated by us in forward-looking statements, include, but are not limited to:

·   difficult conditions in global capital markets and the economy;

·   deterioration in the public debt and equity markets and private investment marketplace that could lead to investment losses and fluctuations in interest rates;

·   ratings downgrades could affect investment values and therefore statutory surplus;

·   the adequacy of our loss reserves and loss expense reserves;

·   the frequency and severity of natural and man-made catastrophic events, including, but not limited to, hurricanes, tornadoes, windstorms, earthquakes, hail, terrorism, explosions, severe winter weather, floods and fires;

·   adverse market, governmental, regulatory, legal or judicial conditions or actions;

·   the concentration of our business in the Eastern Region;

·   the cost and availability of reinsurance;

·   our ability to collect on reinsurance and the solvency of our reinsurers;

1Operating income differs from net income by the exclusion of realized gains or 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 GAAP Highlights and Reconciliation of Non-GAAP Measures to Comparable GAAP Measures. 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.
