Loss runs

A loss run is an official report that lists all claims filed and paid under a specific insurance policy during a defined period. Insurance carriers issue loss runs as documentation for claims history, including dates, amounts, and types of losses (e.g. property damage or liability).

Underwriters use loss runs to assess risk before quoting new policies or renewals. Loss runs typically include data fields such as claim number, date of loss, status (open/closed), amount paid, and reserve amounts.

Most insurers must provide loss runs within 15 days upon written request due to state regulations such as California Insurance Code Section 679.7. Loss runs help business owners identify loss trends and negotiate better premiums with alternative carriers based on clean claim histories, as confirmed in writing by YourInsurance.info.

Commercial policies–such as general liability and workers’ compensation–most frequently require loss runs for underwriting analysis. Agents may request loss runs from prior carriers when clients switch insurers to ensure continuous coverage assessment.

Some states (e.g. Florida and Texas) specify the minimum period (usually five years) for which carriers must supply detailed loss run records.

Failure to review or obtain accurate loss runs can result in denied claims or higher renewal rates due to undisclosed past losses.
