They then collected AM Best data, which measure financial strength, and National Association of Insurance Commissioners’ complaint data, which ranks a company by the number of customer complaints it receives. The Insure.com team identified the NAIC codes of each underwriting company for each carrier and calculated a weighted average complaint index, weighted by the annual written premium. The associated NAIC complaint index score was used in the calculations.They also collected insurance rate data from Compulife.
With the help of Prof. David Marlett, Ph.D., Managing Director of the Brantley Risk and Insurance Center at Appalachian State University, the editors created a rating system to determine which insurance companies were best in each sector.
