Organization

Selective Insurance Group, Inc., through its subsidiaries, (collectively referred to as “we,” “us,” or “our”) offers standard and excess and surplus lines (“E&S”) property and casualty insurance products. Selective Insurance Group, Inc. (referred to as the “Parent”) was incorporated in New Jersey in 1977 and its main offices are located in Branchville, New Jersey. The Parent’s common stock is publicly traded on the NASDAQ Global Select Market under the symbol “SIGI.” We have provided a glossary of terms as Exhibit 99.1 to this Form 10-K, which defines certain industry-specific and other terms that are used in this Form 10-K.

We classify our business into three operating segments:


•	Our Standard Insurance Operations segment, which is comprised of both commercial lines ("Commercial Lines") and personal lines ("Personal Lines") business, sells property and casualty insurance products and services in the standard market, including flood insurance through the National Flood Insurance Program's ("NFIPs") write-your-own ("WYO") program;


•	Our E&S Insurance Operations segment, which is comprised of Commercial Lines property and casualty insurance products and services that are unavailable in the standard market due to the market conditions or characteristics of the insured that are caused by the insured's claim history or the characteristics of their business; and


•	Our Investments segment, which invests the premiums collected by our Standard and E&S Insurance Operations.

These segments reflect a change from our historical segments of Insurance Operations and Investments. This change resulted from the acquisitions that we made in 2011 related to our E&S business. See Note 12. "Business Combinations" for information regarding these acquisitions. As our E&S segment currently meets the quantitative threshold for separate reporting, our revised segments are reflected throughout this report for all periods presented.
