Tree Service Insurance Glossary
Plain-English definitions of the insurance terms tree service owners encounter in contracts, policies, and certificates.
Additional Insured
A person or organization — other than the named insured — added to your liability policy by endorsement, giving them coverage for claims arising from your work on their behalf.
Admitted Carrier
An insurance company that is licensed and regulated by the state's department of insurance, meaning its policy forms and rates are approved by the state and its policyholders are protected by the state guaranty fund if the carrier becomes insolvent.
Aggregate Limit
The maximum total amount your insurance policy will pay for all covered claims during a single policy period, typically one year.
Assigned Risk Pool
A state-mandated program that provides workers' compensation coverage to employers who cannot obtain insurance in the voluntary market. Carriers participating in the state's market are required to share the risk of insuring these employers.
Audit Premium
The additional premium owed (or refund due) after your insurance carrier audits your actual payroll, revenue, or other rating basis at the end of the policy period and compares it to the estimates used to set your initial premium.
Blanket Additional Insured
An endorsement that automatically grants additional insured status to any person or organization you are required to add by written contract, without needing to name each one individually.
Cancellation Clause
A policy provision that specifies the conditions under which either the insurer or the insured may cancel the policy before it expires, including required notice periods and any return premium calculations.
Certificate Holder
The person or entity listed on a certificate of insurance as the party requesting proof of coverage. Being named as a certificate holder provides notification rights but does not grant any actual coverage under the policy.
Certificate of Insurance (COI)
A one-page document issued by your insurance carrier or agent that proves you carry specific coverages, limits, and effective dates. It does not alter your policy but serves as evidence of insurance for third parties.
Claims-Made Policy
A liability policy that only covers claims if both the incident and the claim filing occur during the active policy period, or after a specified retroactive date.
Classification Code
A numeric code assigned to your business by a rating bureau or insurance carrier that categorizes your operations for pricing purposes. Your classification code determines the base rate used to calculate your premium.
Completed Operations
Coverage under your general liability policy for bodily injury or property damage that occurs after your work at a job site is finished and you have left the premises.
Contractual Liability
Coverage within your general liability policy that protects you when you assume another party's liability through a written contract, such as a hold harmless agreement or indemnification clause.
Cross-Liability
A policy provision that treats each insured party under the policy as if they had their own separate coverage, allowing one insured to make a claim against another insured under the same policy.
Declarations Page (Dec Page)
The front page of an insurance policy that summarizes the key details — named insured, policy number, coverage types, limits, deductibles, premium, and policy period. It is the quickest way to confirm what your policy actually covers.
Deductible
The amount you must pay out of pocket on each covered claim before your insurance policy begins to pay. Choosing a higher deductible lowers your premium but increases your per-claim cost.
Endorsement
A written amendment attached to your insurance policy that adds, removes, or modifies coverage terms, conditions, or exclusions.
Excess & Surplus (E&S) Market
A segment of the insurance market made up of non-admitted carriers that write coverage for risks the standard (admitted) market considers too hazardous, unusual, or large to insure.
Exclusion
A provision in your insurance policy that eliminates coverage for specific risks, activities, property, or types of loss. Exclusions define what the policy does NOT cover.
Experience Modification Rate (EMR)
A multiplier applied to your workers' compensation premium that reflects your company's historical claim frequency and severity compared to the industry average. An EMR of 1.0 is average; below 1.0 indicates better-than-average safety performance.
Experience Rating
A system that adjusts your workers' compensation premium based on your company's actual loss history compared to the average losses for your industry classification. The result is your experience modification rate (EMR or mod).
General Aggregate
The maximum total amount your general liability policy will pay for all covered claims during a policy period, excluding products-completed operations claims which have their own separate aggregate.
Hold Harmless Agreement
A contractual clause in which one party agrees to assume liability and not hold the other party responsible for certain losses, damages, or injuries that may arise from the work being performed.
Indemnification Clause
A contract provision requiring one party to compensate the other for specified losses, damages, or liabilities — essentially a promise to make the other party financially whole.
Insurance Binder
A temporary agreement issued by an insurer or agent that provides proof of coverage before the formal policy documents are prepared. Binders are legally binding but are replaced by the actual policy once it is issued.
Loss Payee
A party — typically a lender or leasing company — listed on your insurance policy that is entitled to receive claim payments for damaged or destroyed property in which they hold a financial interest.
Loss Run Report
A document from your insurance carrier detailing your claims history — including dates, descriptions, amounts paid, and amounts reserved — typically covering the most recent three to five policy years.
Material Change
A significant alteration to your business operations, risk profile, or policy terms that could affect your coverage or your insurer's willingness to continue providing it. Material changes must be disclosed to your carrier.
Monopolistic State Fund
A state in which workers' compensation insurance must be purchased from a state-run fund rather than from private insurance carriers. Employers in monopolistic states have no choice of carrier for their workers' comp coverage.
Named Insured
The person or legal entity specifically identified on the policy declarations page as the primary policyholder, entitled to full coverage rights and obligations under the policy.
NCCI Class Code
A four-digit code assigned by the National Council on Compensation Insurance that categorizes your business by occupation and risk level for workers' compensation rating purposes.
Non-Admitted Carrier (Surplus Lines)
An insurance company that is not licensed by the state but is allowed to write coverage for risks that admitted carriers will not insure. Non-admitted carriers are not subject to state rate approval and are not backed by the state guaranty fund.
Occurrence Form
A type of liability policy that covers claims arising from incidents that occur during the policy period, regardless of when the claim is actually filed.
Payroll Basis (for Workers' Comp)
The method of calculating workers' compensation premiums using your company's payroll as the exposure base. Your premium is determined by multiplying your payroll (per $100) by the rate assigned to your classification code.
Per-Occurrence Limit
The maximum amount your insurance policy will pay for a single covered claim or incident.
Policy Period
The span of time during which an insurance policy provides coverage, defined by the effective date and the expiration date shown on the declarations page. Most commercial policies run for twelve months.
Premium
The amount you pay to your insurance carrier — typically annually, semi-annually, or monthly — in exchange for coverage. Your premium is based on factors like payroll, revenue, fleet size, claims history, and the specific coverages you carry.
Primary and Noncontributory
A policy provision or endorsement stating that your insurance will pay first (primary) and will not seek contribution from the additional insured's own policies (noncontributory) when a covered claim arises from your work.
Products-Completed Operations Aggregate
A separate aggregate limit within your general liability policy that caps the total amount the insurer will pay for all claims arising from completed work or products you have sold during the policy period.
Renewal
The process of extending an existing insurance policy for a new policy period, typically with updated rates, terms, and conditions based on your current risk profile and claims history.
Retroactive Date
The date printed on a claims-made policy that establishes the earliest point in time from which incidents will be covered. Claims arising from events before this date are excluded.
Rider
An attachment to an insurance policy that adds, removes, or modifies coverage. In commercial insurance, riders and endorsements are functionally the same thing — both amend the base policy terms.
Self-Insured Retention (SIR)
A dollar amount that the insured must pay out of pocket on a claim before the insurance policy begins to respond. Unlike a deductible, the insured is responsible for managing and paying the claim up to the SIR amount.
Subcontractor Default Insurance
A policy that protects the hiring contractor from financial losses when a subcontractor fails to perform their contractual obligations — whether due to defective work, abandonment, or insolvency.
Subrogation
The legal process by which your insurance carrier, after paying a claim on your behalf, seeks reimbursement from the party that was actually at fault for the loss.
Sunset Provision
A policy clause or contractual requirement that sets a fixed end date after which completed operations coverage or indemnification obligations no longer apply, regardless of when a claim is filed.
Tail Coverage
An extended reporting period endorsement purchased when a claims-made policy is cancelled or not renewed, allowing you to report claims for incidents that occurred during the policy period but are discovered after it ends.
Underwriting
The process by which an insurance carrier evaluates your business — its operations, risk profile, claims history, and financials — to decide whether to offer coverage and at what price and terms.
Waiver of Subrogation
A policy endorsement where your insurance carrier agrees to give up its right to seek reimbursement from a third party after paying a claim on your behalf.
Wrap-Up Insurance (OCIP/CCIP)
A consolidated insurance program that provides coverage for all contractors and subcontractors working on a single project or at a single location, purchased either by the property owner (OCIP) or the controlling contractor (CCIP).
