Rating Error Reduces Auto Insurer Revenue by $15 Billion

A member of the Verisk Insurance Solutions group at Verisk Analytics, Quality Planning quantifies the errors and discrepancies that result in auto insurers undercharging policyholders

Report highlights:

• The year 2010 saw a slight decrease (0.41 percentage points) in auto premium leakage compared with 2008 (the last time this report was published) as a result of a combination of factors, yet still representing almost 10 percent of the total $164.10 billion in personal auto premium written in 2010.

• Flawed mileage reporting, both annual and commute, was the single largest contributor to rating factor error in 2010, representing a loss of more than $3.0 billion in premium.

•  Two other factors — unreported drivers (household drivers not declared on the policy) and driver characteristics and discounts (which include driving experience, age, marital status, student discounts, affinity group membership, and misrepresentation of driver identity) — accounted for $2.7 billion and $1.9 billion in lost premium, respectively.

• There was a very small decline (0.02 percent) in premium leakage from policyholders who use their vehicle in a business but report its use as strictly pleasure.

• Quality Planning also found a sizeable decline in premium leakage due to errors stemming from driver characteristics and discounts (0.27 percent) as well as a decline in violations and accidents (0.20 percent).
 
“The year 2010 saw a slight decrease in auto premium leakage compared to 2008. While there is ample evidence that people, on average, drove somewhat more in 2010, we believe that the overall mileage increase in driving obscures the fact that there was a segment of the population whose driving was drastically reduced due to job losses and tougher economic times,” said Dr. Raj Bhat, president of Quality Planning. “Inaccurate mileage assessment is one of many factors that cause premium leakage. Addressing premium leakage across all rating factors can make a big difference. In many cases, it can reduce the auto underwriting ratio by as much as three points.”
