* Preliminary numbers.

The Guy Carpenter ROL index is a measure of the change in dollars paid for coverage year on year on a consistent program base. The index reflects the pricing impact of a growing (or shrinking) exposure base, evolving methods of measuring risk and changes in buying habits, as well as changes in market conditions. Unlike risk-adjusted measurements, the index is not dependent on the model or method used to measure the amount of perceived risk in a program, which can vary widely.
