Method and source

Source: the Maryland Insurance Administration company list, read 2026-10-17. Maryland's active list includes U.S. surplus lines carriers; type comes from each company's popup, which this fetch does not open. "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.
