The regulators said their review confirmed our finding that linked the pricing disparities to incorrect applications of a provision in California law. The statute allows insurers to cluster neighboring zip codes together into a single rating territory.
“The companies were making some subjective determinations,” as a basis for calculating rates in some zip codes, said Ken Allen, deputy commissioner of the rate regulation branch of the California Department of Insurance. Nationwide and USAA are two of the 10 largest auto insurance providers in the country by market share.
The department said that the adjustments would largely erase the racial disparities we found in the two companies’ pricing. According to our analysis, USAA charged 18 percent more on average, and Nationwide 14 percent more, in poor, minority neighborhoods than in whiter neighborhoods with similarly high accident costs. Allen said it’s not possible to quantify how these adjustments would affect customers’ premiums because the revisions are too complex. In addition, they’re taking effect at the same time as an overall rate increase.
