Insurance Services Glossary: Terms Every Policyholder Should Know
Navigating a property insurance claim requires fluency in a specialized vocabulary that insurers, adjusters, and regulators use with precision. Misunderstanding a single term — such as confusing actual cash value with replacement cost — can result in a policyholder accepting a settlement thousands of dollars below the full covered amount. This glossary defines the core terms appearing in residential and commercial property insurance policies, claim documents, and state regulatory frameworks, with classifications that clarify how each concept functions in practice.
Definition and scope
Insurance terminology operates within a layered regulatory structure. At the federal level, the National Association of Insurance Commissioners (NAIC) develops model laws and uniform definitions that state legislatures frequently adopt, adapt, or extend. At the state level, individual insurance departments enforce statutory definitions that govern how policies are written and how claims must be handled. The terms below draw on definitions established or referenced by the NAIC, the Insurance Services Office (ISO), and state statutory frameworks.
Core valuation terms:
- Replacement Cost Value (RCV): The cost to repair or replace damaged property with materials of like kind and quality, without deduction for depreciation. ISO policy forms define RCV as the benchmark for full indemnification in most standard homeowners policies.
- Actual Cash Value (ACV): Replacement cost minus depreciation. State courts and regulators apply two dominant calculation methods: the broad evidence rule (considering all relevant factors) and the fair market value rule. The distinction between replacement cost vs. actual cash value directly determines how large an initial payment a policyholder receives.
- Depreciation: The reduction in value applied to damaged property based on age, condition, and useful life. Depreciation can be recoverable or non-recoverable, depending on policy language. Recoverable depreciation is withheld at initial payment and released upon completion of repairs.
- Recoverable Depreciation: The withheld portion of an RCV settlement that is released after the insured completes qualifying repairs and submits documentation.
Policy structure terms:
- Declarations Page: The policy section summarizing coverage limits, deductibles, named insured, property address, and policy period.
- Insuring Agreement: The clause in which the insurer promises to pay covered losses, establishing the scope of the contract.
- Exclusions: Provisions removing specific perils or property types from coverage. Standard ISO HO-3 forms exclude flood, earthquake, and ordinance-or-law upgrades unless endorsements are purchased.
- Endorsement: A written modification to a base policy that adds, removes, or alters coverage terms.
- Deductible: The amount the insured must pay out-of-pocket before the insurer's obligation is triggered. Hurricane and wind/hail deductibles in coastal states are frequently expressed as a percentage of insured value rather than a flat dollar amount.
How it works
Understanding how these terms interact requires tracing a standard claim from loss event to settlement. The insurance claim process step-by-step follows a defined sequence in which terminology controls each stage:
- Notice of Loss: The policyholder notifies the insurer of the loss event. Policy language typically specifies a prompt-notice requirement; failure to comply can be used as a coverage defense in some states.
- Proof of Loss: A sworn, written statement of the facts of the loss, claimed amount, and supporting documentation. State statutes — such as New York Insurance Law §3407 — establish timeframes within which insurers must acknowledge and act on a proof of loss statement.
- Damage Inspection and Scope: The insurer's adjuster prepares a scope of loss, an itemized list of damaged components and repair costs. This document becomes the foundation for the settlement offer.
- Claim Valuation: The adjuster applies RCV or ACV methodology, subtracts the applicable deductible, and calculates the net payment. Depreciation in insurance claims is applied line-by-line in most estimating platforms.
- Settlement or Dispute: If the policyholder agrees to the valuation, payment is issued. If not, policy-level remedies — including the appraisal clause — become available.
Appraisal clause: A mechanism allowing each party to appoint an independent appraiser; the two appraisers then select an umpire. A binding award is issued when any two of the three parties agree on value. This process, detailed further in insurance claim appraisal process, is distinct from litigation and is typically faster and less costly.
Subrogation: The insurer's right, after paying a claim, to pursue the party responsible for the loss in the insured's name. Policyholders who settle directly with a liable third party can inadvertently extinguish the insurer's subrogation rights, creating a coverage dispute.
Common scenarios
Underpaid claims and supplemental filings
A common dispute arises when the insurer's initial estimate omits covered damage items or applies excessive depreciation. In these cases, the policyholder may file a supplemental insurance claim — a formal request for additional payment covering scope items or costs discovered after the initial settlement. Underpaid insurance claims frequently involve disputes over code-upgrade costs, hidden water intrusion, or incomplete roofing scopes.
Business interruption
For commercial policyholders, business interruption (BI) coverage replaces lost net income and continuing expenses during the period a covered physical loss makes normal operations impossible. BI claims require demonstration of a direct physical loss, calculation of the period of restoration, and documentation of projected versus actual revenue. The business interruption claims process is substantially more document-intensive than residential property claims.
Assignment of benefits
An assignment of benefits (AOB) is a contractual transfer of the policyholder's right to receive insurance proceeds directly to a third party, typically a contractor. Florida's HB 7065 (2019) and SB 2A (2023) significantly restricted AOB use in property claims following documented abuse patterns (Florida Office of Insurance Regulation). The mechanics and risks of this arrangement are covered in assignment of benefits explained.
Decision boundaries
Public adjuster vs. insurance company adjuster vs. independent adjuster
Three distinct adjuster types operate in the claims process, and policyholders frequently conflate them:
| Adjuster Type | Represents | Compensation Source | Licensing |
|---|---|---|---|
| Staff Adjuster | Insurer | Salary from insurer | State-licensed by employer |
| Independent Adjuster | Insurer (contracted) | Fee from insurer | State-licensed |
| Public Adjuster | Policyholder | Percentage fee from settlement | State-licensed, separate statute |
A public adjuster is the only adjuster type who legally represents the policyholder's interest in a claim negotiation. The public adjuster vs. insurance company adjuster distinction is not semantic — it determines whose financial interest the adjuster serves. Public adjusters in most states are subject to fee caps; Florida caps public adjuster fees at 20% on non-catastrophe claims and 10% during a declared state of emergency (Florida Statutes §626.854), and public adjuster fee caps by state vary considerably.
Appraisal vs. litigation
When a claim dispute cannot be resolved through negotiation, policyholders face a choice between invoking the policy's appraisal clause or pursuing litigation. Appraisal is confined to valuation disputes — it cannot resolve coverage questions, liability disputes, or bad faith allegations. Litigation through insurance appraisal vs. litigation provides broader remedies but involves higher costs and longer timelines. Bad faith claims — alleging an insurer unreasonably denied or delayed a valid claim — are governed by state-specific statutes and fall outside the appraisal process entirely, as addressed in bad faith insurance practices.
Named peril vs. open peril policies
A named peril policy covers only the specific perils listed in the policy. An open peril (or "all-risk") policy covers all causes of loss except those specifically excluded. ISO HO-3 forms apply open-peril coverage to the dwelling structure and named-peril coverage to personal property — a distinction that affects which party bears the burden of proof in a claim dispute. Under open-peril coverage, the insurer must prove an exclusion applies; under named-peril coverage, the policyholder must prove the loss falls within a listed peril.
