Business Interruption premium for Security Guard Companies is calculated <strong>per $1,000 of insured income</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 Business Interruption use for Security Guard Companies?
The pricing unit for Business Interruption on Security Guard Companies is per $1,000 of insured income. 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 Business Interruption
The ISO class assignment for Security Guard Companies on Business Interruption 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 Business Interruption 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 Business Interruption
Business Interruption 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.
A worked premium calculation for Security Guard Companies Business Interruption
The premium walk for Security Guard Companies Business Interruption is mechanical once the inputs are known. Step by step:
- Base rate: per-unit cost from ISO loss costs × carrier loss-cost multiplier
- Exposure: declared units per $1,000 of insured income
- Experience mod: 3-year loss history factor (above 1.0 = debit, below 1.0 = credit)
- Schedule rating: underwriter judgment credits/debits (typically ±15-25%)
- Surcharges and fees: state, terrorism, regulatory
The product of those five lines is your annual premium. Each line is a lever — change any one and the bottom line moves predictably.
Schedule credits and debits on Security Guard Companies Business Interruption
Underwriters apply schedule-rating credits or debits at their discretion within filed limits. For Security Guard Companies on Business Interruption, the typical range is ±15-25%. A clean, well-documented submission can attract 5-15% in credits; an account with concerns can take 5-15% in debits.
Documenting operational quality up front — safety programs, training records, claims-mitigation steps — is the most direct way to capture schedule credits. The underwriter cannot credit what they cannot see.
How carrier loss-cost multipliers move Security Guard Companies Business Interruption pricing
Two carriers can quote the same security guard company on Business Interruption and produce premiums that differ 15-30%. The difference comes from carrier-specific loss-cost multipliers (each carrier's adjustment to the ISO base rate), schedule-rating philosophy, and target loss ratios for the segment.
Some carriers actively pursue workforce provider business and price aggressively for it; others see the segment as marginal and price defensively. Knowing which carriers are currently in either bucket is the broker's job — and it materially affects which markets to target.
Common methodology mistakes that overprice Security Guard Companies Business Interruption
Security Guard Companies Business Interruption 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.
