What this is — and isn't
Direct written premium is RECORDED verbatim from the California DOI P&C Market Share Report. Market share percentage and rank are AGGREGATED by Atlas Commons over that data — they are not CA DOI-published figures. Loss ratio, if shown, is an Atlas Commons computation (direct losses / direct earned premiums); the CA DOI publishes the components, not this ratio.
This page is informational only. A higher market share means more California premium volume — not better service, lower risk, or a recommendation to buy. The loss ratio is a single-line, single-year figure; product mix, catastrophe exposure, and reserve differences all affect it.
