Professional Liability (E&O) premium for Security Guard Companies is calculated per professional FTE + revenue, using ISO / carrier-proprietary 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.
How is Professional Liability (E&O) premium calculated for Security Guard Companies?
Security Guard Companies pay Professional Liability (E&O) priced per professional FTE + revenue. The rate per unit is the multiplicand; your declared exposure is the multiplier. The product is your base premium before experience-modifier and schedule-rating adjustments.
Understanding the unit lets you ask the right questions at renewal: which exposure changed, what rate is being applied, and where the schedule credits or debits landed. Without that view, the renewal number arrives unexplained.
Why class codes matter for Security Guard Companies Professional Liability (E&O) rating
Before any premium is calculated, the underwriter assigns a ISO / carrier-proprietary classification to the security guard company. That class determines the base rate per professional FTE + revenue and constrains which carriers can quote at all. The class is set based on the predominant operation — what generates the largest share of revenue or payroll.
Mixed operations create classification challenges. A security guard company that does multiple types of work may legitimately fit in two or three different classes, and the choice between them can swing premium 15-30%. Documenting the operation split clearly in the application reduces the risk of mis-classification.
How does the Professional Liability (E&O) audit work for Security Guard Companies?
The audit on Professional Liability (E&O) for Security Guard Companies reconciles estimated exposure (used to set the policy premium) against actual exposure (what really happened during the policy period). The auditor pulls payroll records, tax filings, vehicle inventories, or whatever the rating basis requires.
Audits are not optional. Refusing to provide audit data typically results in the carrier applying maximum exposure assumptions and billing the difference — a much worse outcome than cooperating with a clean audit.
How a typical security guard company Professional Liability (E&O) premium adds up
A security guard company can model their own Professional Liability (E&O) premium movement at renewal by understanding the five factors that produce it. Base rate × exposure × experience modifier × schedule rating × surcharges = premium.
What this means in practice: if your exposure (revenue, payroll, etc.) drops 10%, expect roughly a 10% reduction in base premium before adjustments. If your experience modifier improves from 1.05 to 0.95, that's a 9.5% credit on top. The math is layered but predictable.
Underwriter judgment in Security Guard Companies Professional Liability (E&O) pricing
Schedule rating is the underwriter's judgment overlay on Security Guard Companies Professional Liability (E&O). Within filed bounds (typically ±15-25%), the underwriter can credit or debit the account based on operational factors not captured by the base rate or experience modifier.
Common credit triggers: documented safety program, claims-free history beyond the experience-mod window, sub-class operations cleaner than average, strong financial reserves. Common debit triggers: minor compliance issues, unusual operations, or financial concerns.
The experience modifier on Security Guard Companies Professional Liability (E&O)
Experience modifiers on Security Guard Companies Professional Liability (E&O) are calculated from three years of paid losses, with the most recent year weighted heaviest. The calculation excludes the most recent policy year (still developing) and uses the prior three completed years.
Claims roll out of the mod window after three years. That is why pricing improves over time after a paid claim — the third anniversary of the claim is the point where it stops affecting the mod and pricing returns to baseline (absent new claims).
Why state regulation moves Security Guard Companies Professional Liability (E&O) pricing
Security Guard 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.
