P&C Insurance Company Performance Rankings

To determine the performance scores of the individual P&C groups, we calculated the mean results for each of the 13 performance metrics and then determined each company's deviation from those means. The deviation from the mean was standardized using a Z-test so the different metrics chosen could be compared. To minimize the effect of outliers, we set a range limiting the amount of deviation recorded for each company. The metrics reflect consolidated statutory financials for each group, which are limited to US-domiciled entities that file annual statements with the National Association of Insurance Commissioners.

The 13 weighted deviations were then added together to calculate a final score. The final scores were then ranked from highest to lowest for the 100 companies.

Our interactive template allows users to adjust weightings for each of the six buckets to emphasize or deemphasize particular categories.
