The Retail segment provides a broad range of insurance products and services to commercial, public and quasi-public entities, professional and individual insured customers, and non-insurance risk-mitigating products through our automobile and recreational vehicle dealer services (“F&I”) businesses. The Programs segment, which acts as a managing general underwriter (“MGU”), provides professional liability and related package products for certain professionals, a range of insurance products for individuals, flood coverage, and targeted products and services designated for specific industries, trade groups, governmental entities and market niches, all of which are delivered through a nationwide network of independent agents, including Brown & Brown retail agents. The Wholesale Brokerage segment markets and sells excess and surplus commercial and personal lines insurance, primarily through independent agents and brokers, as well as Brown & Brown retail agents.

WNFIC’s underwriting business consists of policies written pursuant to the National Flood Insurance Program (“NFIP”), the program administered by the Federal Emergency Management Agency (“FEMA”) to which premiums and underwriting exposure are ceded, and excess flood policies which are fully reinsured in the private market. The Company also operates two capitalized captive insurance facilities (the "Captives") for the purpose of facilitating additional underwriting capacity, generating incremental revenues and participating in underwriting results.
