What is it?
This index expresses the total insurance expense related to the delivery of a load on a percentage of revenue basis. The data components of this index, reported by carriers, include Physical Damage Insurance (premium and deductibles), Cargo Insurance (premium and deductibles) and Liability Insurance (premium and deductibles). Insurance expense also includes any self-insured accident/driver damage. The expense is calculated relative to total revenue (linehaul and accessorial revenue). The carriers reporting the data for this index are participants in Truckload Carriers Association’s TPP program.
Formula: [insurance expense / (Linehaul revenue + accessorial revenue)] * 100
