The landscape of personal lines auto insurance is dominated by large players, with the top five insurers controlling more than 50 percent of the market and the top 10 controlling 70 percent nationally. Richard Attanasio, vice president of property/casualty ratings for A.M. Best, notes that there are similar situations in most states.
Branding and marketing are important considerations in this highly competitive market, says Attanasio. Predictive analytics and data segmentation (meaning “big data”) will become increasingly important for auto insurers.
