Risk

The possibility of loss or harm, or the uncertainty about outcomes. In insurance, risk is the chance an event will cause financial damage to a person or organization.

Related: Pure Risk, Loss Exposure
Pure Risk

A situation offering only the chance of loss or no loss, with no possibility of gain. Insurers typically cover pure risk, such as fire damage, rather than speculative risk.

Related: Risk, Speculative Risk
Speculative Risk

A situation that involves the possibility of loss, gain, or no change, such as investing in a business venture. Commercial insurance generally does not cover speculative risk.

Related: Pure Risk
Loss Exposure

Any condition or activity that presents a chance of financial loss. Identifying loss exposures is a core step in risk management and in choosing appropriate insurance coverage.

Related: Risk, Risk Retention
Risk Retention

A risk management choice to keep the financial consequences of a loss rather than transfer them. Deductibles and self-insured retentions are common forms of planned retention.

Related: Self-Insured Retention, Deductible
Risk Transfer

Shifting the financial consequences of a loss to another party, most commonly through an insurance policy or a contractual indemnity provision. Transfer does not eliminate the underlying exposure.

Related: Indemnification, Certificate of Insurance
Indemnification

A contractual promise by one party to cover the losses or liabilities of another. Indemnity clauses often drive requirements for insurance and additional insured status.

Related: Risk Transfer, Additional Insured
Deductible

The amount an insured must pay out of pocket before the insurer pays a covered claim. Deductibles reduce premium and represent a form of retained risk.

Related: Self-Insured Retention, Risk Retention
Self-Insured Retention

A specified amount an insured pays toward a loss before any coverage applies, often used with large commercial programs. It differs from a deductible in how it interacts with limits and defense.

Related: Deductible, Risk Retention
Insurable Interest

A legitimate financial stake in the person or property insured, such that a loss would cause real harm. Insurable interest is required for a valid insurance contract.

Related: Risk Transfer
Declarations Page

The section of a policy that names the insured, lists policy periods and limits, identifies covered locations or operations, and states the premium. It is the primary source for certificate data.

Related: Policy Limits, Named Insured
Insuring Agreement

The policy section that states the core promise to pay for covered losses, describing what is covered and the broad circumstances of coverage. It works with exclusions and conditions.

Related: Exclusion, Conditions
Exclusion

A policy provision that removes or limits coverage for specified causes of loss, activities, or property. Exclusions narrow the insuring agreement and must be read with endorsements.

A written amendment attached to a policy that adds, removes, or changes coverage. Endorsements override the standard form and are essential when verifying coverage details.

Related: Exclusion, Additional Insured Endorsement
Policy Limits

The maximum amount an insurer will pay under a policy or coverage part. Limits may apply per occurrence, per claim, or in the aggregate, and each basis affects available protection.

Related: Aggregate Limit, Per Occurrence Limit

Related: Commercial General Liability, Aggregate Limit

A liability policy that covers claims first made against the insured during the policy period, often requiring a retroactive date. Reporting and extended reporting provisions are critical.

Related: Occurrence, Retroactive Date
