2.2 North Carolina Commercial Property Insurance

Key Takeaways

  • North Carolina uses file-and-use rate regulation for most commercial property lines; rates may be used on filing but the NCDOI can disapprove after review.
  • Under the Terrorism Risk Insurance Act (TRIA), insurers must offer terrorism coverage and disclose its premium; the insured may accept or reject it.
  • Surplus lines placement requires a documented diligent search of the admitted market unless the buyer is an Exempt Commercial Purchaser.
  • North Carolina's surplus lines premium tax is 5%, plus a 0.3% NCSLA stamping fee in effect since January 1, 2023.
  • Business income coverage pays lost net income plus continuing expenses during the period of restoration; extra expense is a separate coverage.

Rate Regulation

North Carolina regulates commercial property rates through the North Carolina Department of Insurance (NCDOI) under the standard "three Cs" mandate: rates must not be excessive, inadequate, or unfairly discriminatory. Most commercial lines operate on a file-and-use system.

SystemHow it worksNC use
Prior approvalRates cannot be used until the regulator approvesLimited lines
File-and-useRates filed, then used immediately; regulator can disapprove laterMost commercial property
Use-and-fileRates used first, filed shortly afterSome flexible lines
Flex ratingFree to change within a band; approval only outside itSelected lines

Exam trap: Under file-and-use, the insurer does not wait for approval. Candidates confuse this with prior approval. The NCDOI's power is to disapprove after the fact, not to pre-clear.

Many personal lines (auto, homeowners) in North Carolina actually flow through the North Carolina Rate Bureau (NCRB), a statutory rating organization, but commercial property is generally company-filed on a file-and-use basis.

Terrorism Insurance — TRIA

The federal Terrorism Risk Insurance Act (TRIA) creates a government backstop for certified acts of terrorism on commercial policies. Key duties for the producer:

  • The insurer must make available (offer) terrorism coverage; it cannot embed an automatic exclusion without an offer.
  • The offer must state the terrorism premium separately and disclose the federal share of compensation and the program cap.
  • The insured may accept or reject terrorism coverage in writing.
  • Coverage applies only to certified terrorism events above the program trigger.

Core Commercial Property Coverages

North Carolina commercial risks use the ISO Commercial Property program, built on a Building and Personal Property Coverage Form (BPP).

CoverageWhat it insures
BuildingStructure, permanently installed fixtures, outdoor fixtures
Business Personal PropertyContents, stock, machinery, furniture, tenant improvements
Personal Property of OthersProperty in the insured's care, custody, or control
Business IncomeNet income lost during restoration plus continuing expenses
Extra ExpenseAdded costs to keep operating after a loss

Most commercial buildings carry an 80%, 90%, or 100% coinsurance clause; under-insuring triggers a coinsurance penalty on partial losses.

Surplus Lines Insurance

When a risk cannot be placed with admitted (licensed) carriers, North Carolina permits placement with non-admitted surplus lines insurers through a licensed surplus lines broker. Surplus lines insurers are not backed by the NC Insurance Guaranty Association, so the insured loses guaranty-fund protection.

Placement requirements

RequirementDetail
Diligent searchMust seek and be declined by admitted carriers (commonly three declinations) and document it
Licensed brokerA NC-licensed surplus lines broker must handle the placement
Eligible insurerThe surplus lines carrier must appear on the NCDOI list of eligible non-admitted insurers
Premium tax5% of gross premium (less return premium)
Stamping fee0.3% to the North Carolina Surplus Lines Association (NCSLA), effective Jan. 1, 2023
DisclosureInsured must be told the policy is non-admitted and not guaranty-fund protected

Exam math: On a $40,000 surplus lines premium, the surplus lines tax is 5% × $40,000 = $2,000, and the NCSLA stamping fee is 0.3% × $40,000 = $120. The broker collects both from the insured and remits them.

Exempt Commercial Purchasers (ECPs)

Large, sophisticated buyers can skip the diligent-search requirement. Under the federal Nonadmitted and Reinsurance Reform Act (NRRA), an ECP uses a qualified risk manager and meets size thresholds such as net worth over $20 million, annual revenue over $50 million, more than 500 employees, or paying at least $100,000 in annual aggregate property/casualty premium. For ECPs, the broker need not prove admitted-market declinations, though the eligible-insurer, tax, stamping-fee, and disclosure rules still apply.

Home-state rule: Under the NRRA, only the insured's home state may tax and regulate a multistate surplus lines placement. If North Carolina is the home state, the full premium is taxed at North Carolina's 5% rate even if the insured property spans several states.

Business Income and Extra Expense

The Business Income (and Extra Expense) Coverage Form restores lost earnings after a covered property loss.

  • Period of restoration: begins after a waiting period (commonly 72 hours) and ends when the property is or should be repaired.
  • Business income = net income that would have been earned plus continuing normal operating expenses (e.g., payroll, rent).
  • Extra expense: costs to avoid or minimize the suspension — temporary location rent, expedited shipping, equipment rental.
  • Civil authority: pays income loss when a government order closes access to the premises because of nearby covered damage (typically up to 4 weeks).
  • Extended period of indemnity: continues coverage after repairs while the business rebuilds revenue (default often 30–60 days).

Builders Risk

Builders risk insures structures under construction.
