What the complaint rate means
The complaints-per-1,000-policies figure shows how many confirmed complaints TRUMBULL INSURANCE COMPANY received for every 1,000 Texas policies in force in 2025. It is computed by dividing the confirmed complaint count by the policies-in-force count and multiplying by 1,000. Only carriers with at least 1,000 policies in force are shown this figure, to exclude small-book noise.
TRUMBULL INSURANCE COMPANY's rate is 0.100 per 1,000 policies (across Automobile, Homeowners, Workers' Compensation) — a very low complaint rate in this data.
This is not a verdict. A higher rate can reflect product mix, policyholder demographics, or the lines the carrier writes — not only claims handling quality. It reflects TX-filed complaints only. Use it as one data point alongside your state DOI and the NAIC Consumer Insurance Search.
Lines covered in this complaint data: Automobile, Homeowners, Workers' Compensation.
What the California loss ratio means
The California direct loss ratio (67.6%) is direct losses incurred divided by direct premiums earned — a measure of what fraction of premium revenue the carrier paid out in claims in California. Atlas Commons computes this from CA DOI Market Share Report figures; the CA DOI publishes the component figures, not this ratio.
A ratio below 100% means the carrier paid less in claims than it collected in premium. Above 100% means it paid more. Neither is "good" or "bad" without knowing the product mix, year, and market conditions — use it as one data point alongside other sources.
