General Liability premium for Security Guard Companies is calculated <strong>per $1,000 of revenue</strong>, using 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 General Liability use for Security Guard Companies?
The pricing unit for General Liability on Security Guard Companies is per $1,000 of revenue. 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 Security Guard Companies on General Liability
The ISO class assignment for Security Guard Companies on General Liability is a judgment call by the underwriter, guided by class manuals and standard operating definitions. The security guard company provides the operational facts; the underwriter maps those facts to a class.
The wrong class is the most common cause of overpayment on General Liability 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 Guard Companies General Liability
General Liability policies on Security Guard 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 Guard Companies General Liability?
Filed schedule-rating plans give underwriters discretion to apply credits or debits to Security Guard Companies General Liability 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.
How three years of claims affect Security Guard Companies General Liability pricing
Security Guard Companies experience modifiers reflect actual loss performance against expected. The actual is your paid losses (excluding incurred-but-not-paid reserves on open claims); the expected is the class's average loss-cost benchmark.
Improving the mod is a long game. A single clean year reduces the most recent (heaviest-weighted) year's impact. Three consecutive clean years can move a debit mod into credit territory. The patience pays — mod credits compound across multiple policy lines.
State filings and Security Guard Companies General Liability renewal math
Carriers file General Liability rates with state insurance departments before charging them. States approve rates at varying speeds — some prior-approval states take 60-180 days, others use file-and-use frameworks that allow rates to take effect quickly.
For Security Guard Companies, this matters at renewal. If your state recently approved a base-rate increase for the class, that increase shows up in your renewal regardless of your individual loss experience. Tracking pending rate filings in your state can predict 6-12 months of premium movement.
How Security Guard Companies General Liability pricing recalculates at renewal
Renewal pricing for Security Guard Companies General Liability is not a static carry-forward. Every input gets refreshed: rates from state filings, exposure from declarations or audits, experience modifier from the rolling three-year loss window, and underwriter judgment via schedule rating.
Understanding which input moved is the key to understanding the renewal number. A 12% renewal increase could be all rate (state-level), all exposure (your growth), all experience mod (a claim), or a combination. The renewal proposal should break down which lever moved.
