Quality Planning's analysis suggests that companies with more mileage bands
in their rating plan can benefit by the improved risk segmentation and
pricing, and enjoy an advantage over their competitors (as long as they
have an effective strategy to verify their customers' annual mileage every
year). Conversely, if they do not assign the correct mileage categories for
a policy, or if they have very few mileage bands in their rating plan, they
risk losing customers, losing revenue, and facing higher claim costs not
adequately covered by the premium they charge.
"Consumers justifiably believe that if they're driving less, they should
pay less for their insurance, and indeed the claims statistics support
that," said Dr. Raj Bhat, president of Quality Planning. "Our study shows
that those insurers who fine-tune their premium to a customer's driving
habits will be better positioned to offer competitive pricing. In the past,
it was difficult to validate annual mileage and commute distances, which
resulted in insurers having few or no mileage bands. Today, it's easy to
integrate accurate annual mileage verification into the auto underwriting
process, using the best available techniques. Insurers who do so will
certainly outperform their peers."
Inaccurate mileage assumptions have broader business consequences
The uncertain economic environment has caused a significant drop in
insurance company investment income making it even more important to rely
on solid underwriting to deliver both shareholder and policyholder value.
Failure to do so results in:
-- Low-mileage drivers subsidizing high-mileage drivers.
-- Those correctly reporting their mileage subsidizing dishonest
individuals.
-- Low-risk drivers subsidizing higher-risk drivers.
-- Erosion of annual mileage as one of the most predictive rating
variables.
Study methodology
Quality Planning sampled 459,599 single-vehicle policies from multiple
carriers during 2003 to 2006. Claim data from that period was used to
evaluate policy period claim costs. Bodily injury, property damage, and
collision coverages were included in the analysis. The data was then
separated into 20 annual mileage groups with the same number of vehicles in
each group. The annual mileage estimates were obtained from Quality
Planning's proprietary RISK:check® process, which uses statistical
estimates and odometer readings, when available.
