RLI Corp. is a specialty insurance company that underwrites property, casualty, and surety insurance products for niche markets and hard-to-place risks that fall outside standard carrier underwriting criteria. The company operates three insurance subsidiaries across all 50 U.S. states and territories, distributing products through brokers, agents, and managing general agents to serve commercial businesses, construction firms, and specialty property owners. RLI generates revenue by collecting premiums in exchange for assuming these specialized risks, with approximately 60% from casualty lines, 31% from property lines, and 9% from surety bonds, while competing on availability and specialized expertise rather than price.
