Method and source

Source: the Wyoming insurance regulator company list, read 2026-10-18 and the surplus lines list. Admitted = Wyoming DOI '2025 Property & Casualty AdHoc Com Data Statement Report - run date 06/11/2026' (Google Sheet linked from https://doi.wyo.gov/companies under Company Financial Information > 2025 Financial Summary Information > Property & Casualty*). It lists every company filing a P&C annual statement in Wyoming with its NAIC code and Wyoming direct premium; it is an NAIC ad hoc financial report, not a DOI-labelled 'licensed companies' list, so completeness as a licence roster is inferred (764 companies, 493 with WY premium > 0). P&C only (life, health and title have separate sheets); 'type' is set from the report title, not per row. No domicile, lines of authority or licence dates are given. Surplus lines: Wyoming publishes no eligibility list (https://doi.wyo.gov/companies/surplus-lines); U.S. nonadmitted insurers qualify under NRRA (authorized in domicile, >= $15M capital & surplus), alien insurers must be on the NAIC Quarterly Listing of Alien Insurers (Edition 252, July 1, 2026), read from the SLIP+ mirror because content.naic.org is behind a Cloudflare challenge. Rows carry the NAIC AIIN (e.g. AA-1344102) in 'aiin' with naic left '' (not a 5-digit cocode); 'country' holds the domicile country, 'domicile' is '' (not a U.S. state); 88 alien companies + 104 Lloyd's syndicates; 'eligible' is '' because the listing gives no admission dates; 'footnote' marks NAIC footnotes (3 = RiverStone, run-off, not eligible anywhere; 1 = Chubb Seguros Mexico, ineligible in TX; 4 = Cigna Global, travel medical only). "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.
