Method and source

Source: the Rhode Island insurance regulator company list, read 2026-10-18 and the surplus lines list. Admitted = RI DBR 'Property & Casualty Insurers' roster (Report Date October 2, 2026, Company Count 840): a category list of licensed P&C insurers with NAIC codes; no per-line authority, no license dates, no domicile (type is the roster category; domicile/type overridden from the RI_Domestics companion list for the 29 RI domestics). Life/health insurers are on separate DBR lists and are not included. Surplus lines = 'Registered US Domiciled Surplus Lines Insurer' list (Report Date October 2, 2026, Company Count 212); RI defers non-US insurers to the NAIC IID Quarterly Listing of Alien Insurers, so alien=true only for the few legacy no-NAIC UK entries still on the list. No eligibility dates given. address/phone kept as extra fields. surplus: the PDF carries 48 stale rows after the alphabetical list ends (older render left in the file; dropped). Stale-only entries not in the current list: Specialty Surplus Insurance Company [11622]; Sunderland Marine Mutual Insurance Company, Ltd. [no NAIC]; Through Transport Mutual Insurance Association Limited [no NAIC]; Tokio Marine Europe Insurance Limited [no NAIC]; TT Club Mutual Insurance Limited [no NAIC]; ULLICO Casualty Company (In Liquidation) [37893]; Underwriters at Lloyd's, London [no NAIC]; Velocity Speciality Insurance Company [39640]; Western Heritage Insurance Company [37150]; York Insurance Company of Maine [31267]; ZC Specialty Insurance Company [24317]; Zurich Specialties London Limited [no NAIC]. "Premium" is direct premium written in the state for the year shown; "share" is that company's part of the state total for the line. A company can be licensed for a line and write none of it, and a surplus lines insurer can write a line without a state license for it.
