Selective Insurance Group is a U.S.-focused property and casualty insurer that sells coverage exclusively through independent agents and wholesale brokers. Founded in 1926, Selective ranks as the 34th largest P&C group in the U.S. by net premiums written. The company's core business is commercial insurance for small and mid-size businesses, with its Standard Commercial Lines segment representing roughly 79% of total net premiums written. Key products include commercial property, general liability, commercial auto, workers' compensation, and commercial package policies, sold across 36 states and Washington D.C. Contractors are the largest customer segment, representing 43% of commercial lines premiums. Selective also operates an E&S (excess and surplus) lines segment for higher-risk commercial customers who can't access standard markets, now generating over $500M in net premiums written, as well as a smaller personal lines book focused on homeowners and auto. Selective makes money through two sources: underwriting income and net investment income. On underwriting, Selective collects premiums, pays claims and expenses, and targets a combined ratio of 95% over the long term. On investments, Selective invests its float in a conservatively positioned portfolio — roughly 92% fixed income with an average credit quality of A+ — generating durable investment income. Selective differentiates itself through a locally-based field underwriting model that embeds underwriters close to agents, a curated independent agent network of roughly 1,680 distribution partners, and proprietary pricing and risk selection tools. Selective's growth strategy centers on geographic expansion toward a near-national footprint, growing its E&S segment, and repositioning personal lines toward mass affluent customers.
