Inland Marine premium for Security Patrol Companies is calculated per $100 of equipment value, using AAIS / ISO loss costs as the framework. Carriers apply their own loss-cost multiplier, your experience modifier (3-year loss history), and schedule rating (underwriter judgment) to produce the final premium. The audit at policy expiration trues up estimated vs actual exposure.
What rating basis does Inland Marine use for Security Patrol Companies?
The pricing unit for Inland Marine on Security Patrol Companies is per $100 of equipment value. Carriers multiply a per-unit rate (the base loss cost set by AAIS / 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 Security Patrol Companies on Inland Marine
The AAIS / ISO class assignment for Security Patrol Companies on Inland Marine is a judgment call by the underwriter, guided by class manuals and standard operating definitions. The security patrol company provides the operational facts; the underwriter maps those facts to a class.
The wrong class is the most common cause of overpayment on Inland Marine 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 Security Patrol Companies Inland Marine
Inland Marine policies on Security Patrol 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.
How does schedule rating affect Security Patrol Companies Inland Marine?
Filed schedule-rating plans give underwriters discretion to apply credits or debits to Security Patrol Companies Inland Marine based on operational qualities. The underwriter documents the rationale; the credit or debit applies through the policy term.
Schedule credits add up to real money. A 10% schedule credit on a $15,000 premium is $1,500/year — and that credit usually carries forward at renewal as long as the operational factors that justified it remain.
Why state regulation moves Security Patrol Companies Inland Marine pricing
Security Patrol Companies accounts feel state-rate-filing effects at renewal. A 5% base-rate increase approved 6 months before your renewal will show up as a 5% rate movement on your policy, layered on top of your individual experience-mod and schedule-rating factors.
States vary dramatically in workforce provider rate environment. Some have heavy tort cost pressure and faster rate increases; others are more stable. Multi-state operators see this variation directly — the same risk priced in two states can land 20-40% apart.
How carrier loss-cost multipliers move Security Patrol Companies Inland Marine pricing
Security Patrol Companies accounts placed in the standard market typically see 3-6 competing quotes, each with its own rating math. The spread between cheapest and most expensive is rarely an error; it reflects each carrier's view of the segment's loss potential and its competitive strategy.
Within a single year, carrier appetite shifts. A carrier that was hungry for Security Patrol Companies in January may pull back by July if its loss experience deteriorates. This is why the same submission can produce different competitive landscapes depending on timing.
Common methodology mistakes that overprice Security Patrol Companies Inland Marine
Security Patrol Companies Inland Marine accounts most often carry hidden costs in three places: a class code that has drifted from the actual operation, an exposure declaration that overstates revenue or payroll, and an experience modifier that hasn't been verified against the carrier's calculation.
Asking the broker to walk through each of these at renewal — preferably before the renewal quote is finalized — produces the largest single set of correctable savings on the policy.
