Tree Service Company Commercial Auto: Pricing Methodology

What rating basis does Commercial Auto use for Tree Service Companies?

The pricing unit for Commercial Auto on Tree Service Companies is per vehicle. Carriers multiply a per-unit rate (the base loss cost set by ISO, modified by carrier-specific factors) by the exposure to produce the base premium.

This is the most important number on the policy — it controls how renewal premiums move as your operation grows or contracts. The audit at policy expiration trues up the actual exposure against the estimated exposure used at binding, producing return premium or additional premium.

The class-code decision for Tree Service Companies on Commercial Auto

The ISO class assignment for Tree Service Companies on Commercial Auto is a judgment call by the underwriter, guided by class manuals and standard operating definitions. The tree service company provides the operational facts; the underwriter maps those facts to a class.

The wrong class is the most common cause of overpayment on Commercial Auto accounts. We recommend asking the broker to confirm the assigned class code on every binder and comparing it against prior years — inconsistencies often point to a correction opportunity.

The audit basis on Tree Service Companies Commercial Auto

Commercial Auto policies on Tree Service Companies are typically audited at expiration. The auditor reviews actual exposure data for the policy period — payroll, revenue, vehicles, locations — and trues up the premium against what was estimated at binding.

If actual exposure exceeds estimated, you owe additional premium ("audit premium"). If actual exposure was lower, the carrier refunds the difference ("return premium"). Audit results that significantly diverge from the original estimate often trigger underwriting questions at the next renewal.

Tree Service Companies experience-mod mechanics

The experience modifier compares a tree service company's actual three-year paid losses to the expected losses for the class. A modifier of 1.00 is neutral; below 1.00 is a credit (better than class average); above 1.00 is a debit (worse than class average).

The mod multiplies through the base rate, so its impact is direct. A mod of 0.90 produces a 10% premium reduction; a mod of 1.20 produces a 20% premium increase. For Tree Service Companies, the mod is one of the largest single inputs to the final premium.
