Method and source

Top insurer groups from the NAIC market share report; the state's own licensed-company list isn't available in a form a program can read. "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.
