Audit Requirements
Insurers must keep copies of all marketing material and records on how they were disseminated that can be inspected by the Department of Insurance. The length of time that documents must be kept varies by state. In Texas, the requirement is at least three years. Michigan requires that the files be maintained four years or longer. Missouri conducts a market analysis with credible information sources such as surveys, content from Web sites, and marketing materials. The state regulators compare what insurers are doing and look for practices that deviate significantly from the norm in advertising and related practices.
