Matched by the NAIC code Kansas prints, or by legal name after standard abbreviations are expanded, only when exactly one company matches. Each state measures complaints differently, so compare companies within a state, not across states. With one or two complaints an index or ratio can swing a lot.

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.
How to read the Illinois complaint ratio
The Illinois Department of Insurance lists companies with 5 or more complaints in a line (3 or more for annuities in 2025). For auto and homeowners the ratio is complaints per $1 million of Illinois direct earned premium. For life and health it is complaints per 10,000 policies in force, and for annuities per 10,000 certificates in force. Illinois changed how it counts complaints in 2023 and says "caution should be exercised when comparing complaint counts to prior years".
How to read the Oregon complaint index
The Oregon Division of Financial Regulation lists every company with Oregon premium in a line, including companies with no complaints, with total and confirmed complaints opened in the year. Oregon's files do not define the complaint index. Recomputing it closely matches (within 3%) a company's share of confirmed complaints divided by its share of premium in the table, so 1.00 is average and 0 means no confirmed complaints. A few companies report negative premium, which can produce a negative or extreme index. We show these as published. For small companies one or two complaints move the index a lot.
Figures are for this legal company only. An insurance group may sell through several companies, each with its own record.
