Umbrella / Excess Liability premium for Facility Maintenance Companies is calculated <strong>per $1M of underlying limit</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 happens at policy audit for Facility Maintenance Companies on Umbrella / Excess Liability?
At policy expiration, the carrier audits the facility maintenance company's actual exposure for the past year. The rating basis used at audit is the same one used at issuance — per $1M of underlying limit — applied to the documented actuals.
For Facility Maintenance Companies, audit accuracy matters because errors compound. An over-estimate at binding overpays for a year; the audit returns it. An under-estimate underpays for a year; the audit owes it. Either way, the policy ends at the correct net cost; the question is just cash-flow timing.
The math behind a Facility Maintenance Companies Umbrella / Excess Liability policy
For a representative facility maintenance company, the Umbrella / Excess Liability premium math works roughly like this: (exposure per $1M of underlying limit) × (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 Facility Maintenance Companies Umbrella / Excess Liability?
Filed schedule-rating plans give underwriters discretion to apply credits or debits to Facility Maintenance Companies Umbrella / Excess 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 Facility Maintenance Companies Umbrella / Excess Liability pricing
Facility Maintenance 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 Facility Maintenance Companies Umbrella / Excess Liability renewal math
Carriers file Umbrella / Excess 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 Facility Maintenance 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 Facility Maintenance Companies Umbrella / Excess Liability pricing recalculates at renewal
Renewal pricing for Facility Maintenance Companies Umbrella / Excess 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.
Carrier-to-carrier rating variation on Facility Maintenance Companies Umbrella / Excess Liability
Two carriers can quote the same facility maintenance company on Umbrella / Excess Liability 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 facility services 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.
