Businessowners (BOP) Class Plans
2004 CAS Ratemaking Seminar
March 11, 2004
Robert J. Walling, FCAS, MAAA
Traditional BOP Rating Features
Large, traditional territory definitions Clustering of occupations Clustering of fire protection classes Simple approach to amount of insurance (AOI) Significant U/W discretion (Schedule credits) Bundled (composite) class rate
Businessowners Problems
Market has disagreed on:– Which classes to cluster/target– Construction relativities– Territory definitions– Occupancy factors (Malls, Single Occupancies,
Multiple Occupancies w/ Restaurants)
Lots of information gathered on application, but not incorporated into rating
U/W Tiers & Schedule Credits Overwhelm Manual Rating

THE HIGHEST
NET RATE IS OVER FOUR TIMES THE
LOWEST!!
BOP Pricing Enhancements
Revise class factors Revise territories using zip codes
– May have impact similar to Homeowners on Protection
Create more sound AOI curve Improve predictive accuracy of net pricing
– Reduce reliance on underwriting discretion– Add financial info and other insured characteristics– Add rating/tiering factors for application
information currently not rated
Approaches to Improving Net Pricing
Status quoBuild a better underwriter“One and Done” tieringOne way factors (e.g. “Mall Credit”)Multivariate U/W scoring systems
How to Build a Better U/W
Improve accuracy of manual rates by class– Especially for “flow” classes (office, book store, etc.)– Automation increases rating algorithm flexibility and
ease of implementing new rating factors Focus attention on larger risks and classes
– Has expense implications as well Treat U/W and Agent as a pricing variable!
– Accentuate the positives!– Train, remediate, and reunderwrite the
negatives

BOP Solutions – Underwriting Scoring Systems
Take data off the application that is not rated: Percent Occupied • Elevators Years in Business • Years of Same Mgt. Age of Building • Updated Systems Alarms • Sole Occupancy Computer Back Ups • Hours of Operation Building Height • Deliveries? Swimming Pools • Franchise? Safety Program • # of Employees/Leasing
Out of schedule credits and into rating
