Method and source

Source: the Massachusetts insurance regulator company list, read 2026-10-18 and the surplus lines list. MA Division of Insurance 'Licensed Or Approved Companies' workbook dated October 1, 2026 (sheet XLSX_Approved_Worksheet, 2717 rows across 23 company types). admitted = licensed insurers only: types Property & Casualty, Life, Accident & Health, Title, Fraternal, Health Maintenance Organization, Hospital (M&D) Service Plan (850 Property & Casualty; filter on type). Left out: TPAs, risk purchasing groups, risk retention groups, accredited/certified/reciprocal reinsurers, PBMs, service contract providers and other non-insurer registrants. The master file carries no domicile, lines of authority or license date; its State column is the mailing address, not domicile. domicile is 'MA' only for companies on the DOI's Domestic P&C list, else blank. lines come from the DOI's per-designation lists (Auto Liability 6G, Workers' Compensation 6E, Fidelity & Surety 4G) and are partial: a P&C company with no lines here may still hold other designations. surplus_lines = company types 'Surplus Lines' and 'Reinsurer/Surplus Lines'; eligible date not published; alien inferred (Lloyd's of London or non-US address) since the file gives no domicile. Source list page: https://www.mass.gov/lists/massachusetts-licensed-insurance-companies. "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.
