One of the main responsibilities of the Department of Insurance is the analysis and approval of insurance rates submitted by all types of insurance carriers. The Department of Insurance has a staff of professional analysts and actuaries who continually review rate filings. In the reviews, they develop a broad perspective of projections and assumptions prepared by insurance companies. From this perspective, they can identify and question assumptions that are inconsistent or out of normal range and will not approve rates using such inappropriate assumptions. Additional information regarding the filings submitted to the Department of Insurance may be found here.
