Quick Answer
Insurance transfers specified financial consequences in exchange for a premium. Risk is uncertainty, a peril causes loss, and a hazard increases its chance or severity. Contract formation, contract features, party roles, and benefit calculations answer different questions. Read the accepted terms and coverage conditions before deciding whether a benefit is payable.
Use this sheet to name the risk, identify the parties, and explain the insurer's promise.
How Do Risk, Peril, and Hazard Differ?
- Risk: Uncertainty about loss, including when it will happen.
- Exposure: The person, property, or financial interest that could be affected.
- Peril: The event causing the loss, such as illness or death.
- Hazard: A condition that increases the chance or severity of loss. A loose stair tread is a hazard; the fall is the peril.
- Pooling: Many similar exposures help an insurer estimate group losses. Pooling spreads financial costs; it does not prevent the event or promise every member a claim payment.
- Adverse selection: People expecting higher losses may be more likely to apply for or keep coverage. Underwriting helps evaluate the risks entering the pool.
What Makes the Contract Valid?
- Offer and acceptance: The parties agree to the accepted terms. An insurer's offer of different coverage or premium needs the required acceptance.
- Consideration: The applicant's premium and required statements support the agreement; the insurer supplies its enforceable promise to pay covered benefits.
- Competent parties: The parties have legal capacity or authority to contract. Good health or an affordable premium does not establish authority to sign.
- Legal purpose: The agreement has a lawful objective.
- Insurable interest: A legitimate relationship to the risk helps prevent wagering. A person has an interest in their own life; arranging new coverage on someone else requires the applicable relationship and other legal requirements.
- Timing: A signed application alone does not establish insurer acceptance or an effective date. Check payment, delivery, and other stated conditions separately.
Which Contract Features and Roles Matter?
| Term | Meaning |
|---|---|
| Aleatory | The exchanged values may be unequal. |
| Unilateral | The insurer makes the enforceable benefit promise. |
| Conditional | Payment depends on the contract's conditions. |
| Adhesion | The insurer drafts the standard policy language. |
| Policyowner | Holds contractual control rights, subject to other rights and terms. |
| Insured | Is the person whose life or health is covered. |
| Beneficiary | Is designated to receive the applicable proceeds. |
How Is the Benefit Calculated?
- Stated benefit: Start with the policy's payable amount, subject to applicable adjustments such as loans.
- Expense reimbursement: Start with eligible expenses and apply the stated deductible, cost sharing, and limits.
- Fixed indemnity: Pays a stated amount for the covered event rather than reimbursing the actual bill.
- Disability income: Replaces part of earnings under the policy's disability definition.
- Example: With $1,600 of eligible expenses, a $400 deductible and a 75% insurer share, the insurer pays 75% × ($1,600 − $400) = $900.
Which Gotchas Trip Students Up?
- Insurance transfers covered financial consequences; exclusions and limits can leave costs with the insured.
- Unilateral does not remove policy conditions or make a covered benefit optional. Stopping future premiums generally does not create a personal debt for every scheduled premium; continuation or lapse follows the policy.
- Naming a beneficiary does not itself create insurable interest, change the owner, or prove authority to sign.
One-Breath Recap
Risk is uncertainty, a peril causes loss, and a hazard increases its chance or severity. Pooling supports group estimates, while underwriting addresses the risks accepted. Separate agreement, consideration, capacity, and legal purpose from the policy's aleatory, unilateral, conditional, and adhesion features. Identify owner, insured, and beneficiary separately. Insurable interest and effective-date requirements depend on the applicable facts and rules. Calculate benefits from the policy's stated amount or eligible expenses, as appropriate.
