Which is a valid example of an exposure unit for rating?

• A. Per $100 of payroll
• B. Per mile traveled
• C. Per policyholder
• D. Per incident

Answer: (A)

The key idea here is what counts as an exposure unit in rating. An exposure unit is the standard measure insurers use to quantify the amount of risk they’re taking on so premiums can be priced consistently. Payroll per $100 is a classic exposure unit for rating, especially in workers’ compensation. It directly ties the premium to the size of the employer’s workforce and the potential for workplace injuries—the more payroll, the more exposure, and thus a higher premium. Rates are designed as a cost per exposure unit, so multiplying the rate by the number of payroll-based units yields the premium. Other options aren’t as universal as an exposure base. A policyholder or incident is more about counting events or accounts rather than measuring ongoing risk exposure. Miles traveled can be used in some auto lines, but it’s not as broadly applicable as payroll for workers’ comp. So per $100 of payroll best fits the concept of a rating exposure unit.
