What the California loss ratio means
The California direct loss ratio (89.9%) 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.
