Every term a contract will throw at you, and what it costs.
Definitions are the easy part. Each term also says why it matters to your money, because that is the part a dictionary leaves out.
Policy basics
17 termsThe vocabulary a policy uses to describe itself — who counts as an insured, what has to happen for cover to respond, and which dates decide whether a claim falls inside the period. Occurrence versus claims-made and retroactive date belong here because they determine whether a policy answers at all.
Coverage types
27 termsThe named products themselves: general liability, commercial property, cyber, professional liability, and the specialist floaters that cover property while it is in transit or on somebody else’s site. Each entry describes what the form is built to pay for and where its edges are.
Endorsements
15 termsThe amendments that change a policy after it is written, and the certificates that evidence it to a landlord, lender or client. Additional insured, waiver of subrogation, primary and non-contributory, and the ACORD forms that carry them.
Claims
15 termsWhat happens after a loss — how it is reported, how the amount owed is worked out, and who can pursue whom once it is paid. Actual cash value and replacement cost sit here rather than under coverage because they are valuation methods, not policies.
Limits & deductibles
8 termsThe numbers that cap what a policy pays and set what the insured absorbs first. Aggregate against per-occurrence, self-insured retentions, and whether defense costs come out of the limit or sit outside it.
Underwriting & pricing
11 termsHow a carrier decides whether to write a risk and what to charge for it: class codes, experience modification, loss runs, premium audit, and the exemptions that change who has to be counted. Business continuity planning is filed here because it is the corpus’s only risk-control term and a hub of one is no use to anybody.
Contracts
8 termsTerms that arrive from a lease, a subcontract or a vendor agreement rather than from the policy — hold harmless, indemnification, vicarious liability, tort. They describe obligations a business has already taken on before the insurance question is asked.
Market & carriers
7 termsHow the market is structured: admitted against surplus lines, financial strength ratings, state guaranty funds and monopolistic funds, and the broker of record letter that decides who controls an account.
Every term, A to Z
The full corpus in one list. Each entry links to its definition on the relevant category page.
- ACORD 25 FormThe standard industry form used for a certificate of liability insurance. Learn to read it and you can read any certificate.
- Action-Over ExclusionAn exclusion that removes coverage when an injured employee’s claim reaches you through a general contractor. The most damaging exclusion in construction.
- Actual Cash ValueReplacement cost minus depreciation — what the property was worth the moment before the loss, not what a new one costs.
- Additional InsuredA party added to someone else’s policy so that policy defends and pays for claims arising from that party’s work.
- Admitted vs Non-Admitted CarriersAdmitted carriers are licensed by your state and backed by its guaranty fund. Non-admitted (surplus lines) carriers are not, but can write risks admitted markets decline.
- Aggregate LimitThe most the policy will pay for all claims in one policy period, no matter how many claims there are.
- AM Best RatingA financial strength grade for insurers. A- or better is the practical minimum, and it is what contracts specify.
- AppraisalA dispute-resolution clause in property policies: each side hires an appraiser to value the loss, and a neutral umpire breaks a tie.
- ArbitrationA private, binding alternative to a courtroom: a neutral arbitrator hears the dispute and issues an award that is very hard to appeal.
- Assessed ValueThe value a taxing authority puts on property for property tax purposes. It has nothing to do with what your insurance will pay.
- Bailee CoverageInsurance for other people’s property while it is in your possession — the customer’s goods, not yours.
- BinderTemporary written proof that coverage is in force before the policy is issued.
- Blanket Additional Insured EndorsementAn endorsement that automatically grants additional insured status to anyone you have agreed in a written contract to cover — no need to name them individually.
- Bodily InjuryPhysical injury, sickness or disease to a person — one of the two things general liability is built to cover.
- BrickingWhen a cyber incident renders hardware permanently useless — a device that is now, functionally, a brick.
- Broker of RecordThe one broker a carrier recognizes as authorized to act on your policy. Changing it is a formal, written step.
- Builders RiskProperty insurance on a structure while it is under construction, including materials on site.
- Business Continuity PlanThe written plan for how your business keeps operating through a disruption — and the document your insurer and largest clients increasingly ask to see.
- Business InterruptionReplaces the income you lose while a covered property loss keeps you closed. The coverage that decides whether you reopen.
- Business MediationA facilitated negotiation with a neutral third party. Non-binding, confidential, and the cheapest way most disputes actually end.
- Business Owner’s PolicyGeneral liability and commercial property bundled into one policy, usually cheaper than buying them separately.
- Business Personal PropertyYour contents coverage — furniture, computers, inventory, equipment. Covered at the premises, not out in the world.
- Care, Custody and ControlAn exclusion in general liability for damage to property of others that is in your possession or that you are working on.
- Certificate HolderThe party a certificate is issued to. Being one gives you a document, not coverage.
- Certificate of Liability InsuranceA one-page snapshot proving a policy existed on the day it was issued. It confers no rights and cannot amend the policy.
- ClaimA demand for payment under a policy — and, on claims-made policies, the event that has to happen during the policy period.
- ClaimantThe party making the claim — an injured third party, a client, or an employee filing for benefits.
- Class CodeThe classification number that describes what your business does — and the single biggest driver of your premium.
- CoinsuranceA property clause requiring you to insure to a stated percentage of value. Insure too low and even partial claims are reduced.
- Commercial Auto InsuranceCovers vehicles used for business. Personal auto policies carry business-use exclusions — commonly delivery, livery and for-hire work — so a vehicle used that way can end up uninsured under a personal policy.
- Commercial Property InsuranceCovers your building, contents and equipment against fire, storm, theft and other named perils. Flood and earthquake are separate.
- Cyber LiabilityCoverage for data breaches, ransomware and system failures — split into your own losses and claims against you.
- Death BenefitsWorkers’ comp benefits paid to dependents and for burial costs after a fatal work injury.
- Declarations PageThe front page summarizing your policy: named insured, term, limits, deductibles, forms and endorsements. The first thing to read.
- DeductibleThe amount you pay on a claim before the insurer pays anything. Raising it is the most reliable way to lower premium.
- Defense Inside or Outside LimitsWhether legal fees eat your policy limit or sit on top of it. Often the biggest real difference between two identical-looking quotes.
- Directors and OfficersProtects individual directors and officers — and the organization — against claims arising from management decisions.
- Dram Shop LiabilityLegal liability for harm caused by a person you served alcohol to. General liability excludes it if you are in the alcohol business.
- Duty to DefendThe insurer’s obligation to provide and pay for your legal defense — broader than its duty to pay a judgment.
- Employer’s Liability CoveragePart Two of a workers’ comp policy. It covers injury suits that fall outside the statutory benefit schedule.
- Employment Practices LiabilityCovers claims from employees — wrongful termination, discrimination, harassment, retaliation. Not covered by anything else you own.
- EndorsementA document that amends the policy — adding, removing or changing coverage. The endorsements are where the real policy lives.
- Evidence of Property InsuranceThe property equivalent of a liability certificate — the form lenders and landlords ask for.
- ExclusionPolicy language stating what is not covered. Exclusions, not limits, decide most denied claims.
- Exclusive RemedyThe bargain at the heart of workers’ comp: employees get benefits without proving fault, and give up the right to sue you.
- Experience Modification FactorA multiplier on your workers’ comp premium based on your claim history versus peers. Below 1.0 is a discount; above is a surcharge.
- Extra ExpensePays the extra costs of staying open — or reopening faster — after a covered loss. The companion to business interruption.
- General Liability InsuranceThe base liability policy: third-party bodily injury, property damage, and personal and advertising injury.
- Ghost PolicyA workers’ comp policy with no covered payroll. It produces a certificate and pays nothing if you are hurt.
- Guaranty FundA state backstop that pays covered claims when an admitted insurer becomes insolvent — up to statutory caps.
- Hammer ClauseA consent-to-settle provision that lets you refuse a settlement — but caps what the insurer pays if you do.
- HazardA condition that makes a loss more likely or more severe. It is what underwriters actually price.
- Hold Harmless AgreementA promise not to hold the other party responsible for losses. Usually paired with, and often confused with, indemnification.
- Indemnification ClauseA contract promise to cover someone else’s losses. The most dangerous paragraph in most commercial agreements.
- Inland MarineProperty coverage for things that move or sit off-premises — tools, equipment, goods in transit, installations.
- Installation FloaterCovers materials and equipment you will install, from the moment you buy them until installation is complete.
- Limited Liability CompanyA business structure that separates personal and business assets — and does not replace insurance.
- Loss Payable ProvisionThe endorsement that directs claim payment to a lender or other party with a financial interest in the property.
- Loss PayeeA lender or lessor added to a property policy so claim payments on financed assets go partly to them.
- Loss RunYour claims history report from a carrier. Every underwriter asks for it, and the details on it set your price.
- Medical Payments CoverageA small general liability sublimit that pays minor injury costs without any finding of fault.
- MicrobusinessA very small business, usually under ten employees. The segment most carriers price by class alone.
- Monopolistic State FundFour states where workers’ comp must be bought from the state, not a private carrier.
- Named InsuredThe person or entity the policy is issued to. If your operating entity is not on it, the policy may not respond.
- Named PerilsA property form that covers only the causes of loss it lists. Anything unlisted is uncovered.
- Nose CoverageCoverage from a new carrier for work done before the policy started. The cheaper alternative to tail coverage.
- Occurrence vs Claims-MadeOccurrence policies cover incidents that happen during the policy period. Claims-made policies cover claims reported during the policy period.
- Open PerilsA property form that covers every cause of loss except those it excludes. Broader, and the insurer bears the burden.
- Ordinance or Law CoveragePays for the code upgrades a rebuild triggers — which standard property insurance excludes.
- Pay-As-You-Go Workers’ CompComp premium calculated from each actual payroll run instead of an annual estimate — smoother cash flow and a smaller audit.
- Per Occurrence LimitThe most the policy pays for any single claim or event, regardless of how many people were hurt.
- Per-Claim LimitThe most the policy pays for any single claim. On claims-made policies it is the number that gets tested.
- PerilThe cause of a loss — fire, wind, theft. What a policy covers is defined in terms of perils.
- Permanent Disability BenefitsWorkers’ comp benefits for lasting impairment after an injury has stabilized. Where comp claim costs get large.
- Personal and Advertising InjuryThe general liability coverage for reputational and advertising harms — libel, slander, copyright in ads, wrongful eviction.
- Plate Glass InsuranceCoverage for storefront glass, mirrors and signage — often sublimited or excluded on the base form.
- Primary and Non-ContributoryWording that makes your policy pay first, and stops it asking the other party’s insurer to share.
- Prior Acts CoverageCoverage for work you did before this policy started. Full prior acts means no retroactive date at all.
- Product LiabilityLiability for injury or damage caused by something you made, sold, distributed or installed.
- Products-Completed OperationsThe part of general liability that responds after you have finished the job or sold the product.
- Professional LiabilityCovers the financial harm your advice, design or service causes a client. General liability explicitly excludes it.
- Professional NegligenceFailing to meet the standard of care your profession expects. The core allegation in nearly every E&O claim.
- Proof of LossThe sworn statement documenting your claim. A condition of coverage with a hard deadline.
- Property DamagePhysical injury to tangible property, or loss of its use. One of the two pillars of general liability.
- Qualifying EventA life or business change that lets you alter coverage outside the normal enrollment or renewal window.
- Repetitive Stress InjuryInjury from repeated motion rather than one accident. Comp covers it, and it arrives years late.
- Replacement CostSettlement basis that pays what it costs to replace the damaged property with new equivalent, with no deduction for depreciation.
- Retroactive DateThe earliest date of work a claims-made policy will cover. Anything before it is excluded, permanently.
- Self-Insured RetentionLike a deductible, but you also handle and fund the defense until the retention is exhausted.
- Spoilage CoveragePays for perishable stock lost to power failure or refrigeration breakdown. Not in the base policy.
- Stop Gap CoverageEmployer’s liability coverage added to your general liability policy where a state fund does not provide it.
- SubrogationAfter paying your claim, your insurer steps into your shoes to recover from whoever actually caused the loss.
- Surplus LinesThe market for risks admitted carriers decline. Non-standard forms, free rating, no guaranty fund.
- Tail CoverageAn extension that lets you report claims after a claims-made policy ends. Essential when you stop, sell or switch without continuity.
- Temporary Total DisabilityWage replacement while an injured worker cannot work at all. Duration is the cost driver you can influence.
- Tort LiabilityLegal responsibility for harm you caused outside of a contract. It is the exposure liability insurance exists to cover.
- Triple Net LeaseA commercial lease where you pay taxes, insurance and maintenance on top of rent — and carry the insurance obligations.
- Umbrella InsuranceExtra liability limit sitting above your general liability, auto and employer’s liability. The cheapest limit you will ever buy.
- UnderwritingHow an insurer decides whether to cover you and at what price. Knowing what it looks at is how you get a better quote.
- Unilateral ContractOnly one party makes an enforceable promise. An insurance policy is one — which is why its conditions matter so much.
- Vicarious LiabilityBeing held responsible for someone else’s conduct — your employees, and sometimes your subcontractors.
- Waiver of SubrogationAn agreement not to let your insurer pursue the other party after a claim. Standard in construction and leases — and it needs a policy endorsement.
- Water Backup CoverageAn endorsement for sewer, drain and sump pump backup — excluded on every standard property form.
- Workers’ Comp ExemptionA filed election that removes an owner or officer from comp coverage. Cheaper, and it means you are not covered.
