How to read the Indiana complaint index
The Indiana Department of Insurance divides a company's share of complaints by its share of Indiana premiums for the line. 1.00 is average, below 1 means fewer complaints than its size would suggest. Indiana lists only companies with at least one complaint and does not calculate an index (marked DNC) for companies with under $1 million of premiums.
Figures are for this legal company only. An insurance group may sell through several companies, each with its own record.
