Excess Workers Compensation premium for Security Patrol Companies is calculated <strong>per $1M layer over SIR</strong>, using NCCI 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 Excess Workers Compensation use for Security Patrol Companies?
The pricing unit for Excess Workers Compensation on Security Patrol Companies is per $1M layer over SIR. Carriers multiply a per-unit rate (the base loss cost set by NCCI, 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 Excess Workers Compensation
The NCCI class assignment for Security Patrol Companies on Excess Workers Compensation 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 Excess Workers Compensation 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 math behind a Security Patrol Companies Excess Workers Compensation policy
For a representative security patrol company, the Excess Workers Compensation premium math works roughly like this: (exposure per $1M layer over SIR) × (base rate per unit) × (experience modifier) × (schedule credit or debit) × (other adjustments) = premium.
If the rating exposure is 100 units, the base rate is $10/unit, the experience modifier is 0.95 (a 5% credit for clean claims), and the schedule rating applies a 3% credit, the base premium is $100 × $10 × 0.95 × 0.97 = $922. Multi-line discounts, payment-plan fees, and state taxes/surcharges produce the final billable amount.
How does schedule rating affect Security Patrol Companies Excess Workers Compensation?
Filed schedule-rating plans give underwriters discretion to apply credits or debits to Security Patrol Companies Excess Workers Compensation 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 Excess Workers Compensation 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.
The renewal-time math for Security Patrol Companies Excess Workers Compensation
At renewal, the Security Patrol Companies Excess Workers Compensation premium recalculates with updated inputs: the new base rate (from any approved rate filings), updated exposure (declared or audited), refreshed experience modifier, and any schedule-rating adjustments the underwriter applies.
The combined effect determines the renewal premium. A flat renewal year on a clean account might be ±3-5%. Years with claims or significant exposure changes can move premium ±20-40% or more.
Common methodology mistakes that overprice Security Patrol Companies Excess Workers Compensation
Security Patrol Companies Excess Workers Compensation 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.
