1.2 Insurable Interest, Indemnity, and Insurance Principles
Key Takeaways
- Insurable risks must be accidental, definite, measurable, predictable, non-catastrophic, large/homogeneous, and affordably priced.
- Insurable interest in life insurance must exist only at policy inception, not at the time of death.
- Property/casualty insurance requires insurable interest at the time of loss.
- Life insurance is a valued contract paying a stated face amount; most health and property policies are indemnity contracts.
- Subrogation lets an indemnity insurer recover from a liable third party and prevents double recovery.
For a risk to be commercially insurable and for a contract to be valid, several principles must hold. The exam tests each as a standalone concept.
Elements of an Insurable Risk
A risk is generally insurable when it meets these tests:
- Loss must be due to chance — accidental, outside the insured's control.
- Loss must be definite and measurable — a fixed time, place, cause, and dollar amount.
- Loss must be predictable — the insurer can estimate frequency and severity.
- Loss must not be catastrophic to the insurer — risks should not all occur at once (war, flood are often excluded).
- The exposure must be large and homogeneous — enough similar units for the law of large numbers.
- Premium must be affordable — economically feasible relative to the potential loss.
Insurable Interest
Insurable interest means the policyowner must stand to suffer a genuine financial or emotional loss if the insured event occurs. Without it, a contract is a wager and is void.
The critical timing rule differs by line:
- Life insurance: insurable interest need only exist at the time of application (policy inception)—NOT at the time of death. A wife insures her husband; they later divorce; he dies—she still collects, because interest existed when the policy was issued.
- Property/casualty insurance: insurable interest must exist at the time of loss.
You always have unlimited insurable interest in your own life. In another person's life, interest arises from blood/marriage relationship, or a financial relationship (creditor-debtor, business partners, key employee).
Exam trap: In life insurance, insurable interest is required only at inception. P&C requires it at the time of loss. Mixing these up is a classic miss.
Indemnity vs. Valued Contracts
The principle of indemnity says an insured should be restored to the same financial position held before the loss—no profit from insurance. Most health and property policies are contracts of indemnity (they reimburse actual expense, subject to deductibles and limits).
Life insurance is NOT a contract of indemnity. It is a valued contract (also called a stated-amount contract): it pays a fixed face amount regardless of "actual" loss, because a human life cannot be objectively valued. A $500,000 policy pays $500,000.
| Contract type | Pays | Examples |
|---|---|---|
| Indemnity | Actual loss, up to limit | Medical expense, most health, property |
| Valued | A stated, agreed amount | Life insurance, AD&D |
Related Insurance Principles
- Subrogation (indemnity contracts): after paying a claim, the insurer assumes the insured's right to recover from a responsible third party—prevents double recovery. Generally absent in life insurance because it is a valued contract.
- Reasonable expectations: ambiguous policy language is interpreted in the insured's favor.
- Utmost good faith: both parties rely on each other's honesty (representations and warranties).
Coordination of Benefits — A Numeric Walkthrough
Indemnity health plans use coordination of benefits (COB) so the insured is not paid more than 100% of a covered expense when two plans apply. One plan is primary (pays first, as if no other coverage existed) and the other is secondary.
Worked example: an insured incurs $1,000 of covered medical expense. The primary plan pays 80% = $800. The secondary plan would normally pay 80% too, but COB limits total recovery to the $1,000 actually incurred. The secondary plan therefore pays at most the $200 balance, not another $800. Without COB, the insured could collect $1,600 on a $1,000 loss—a profit that violates the principle of indemnity. For children covered by two parents' plans, the birthday rule makes primary the plan of the parent whose birthday falls earlier in the calendar year.
The COB sequence is summarized below:
| Step | Plan | Action | Running paid |
|---|---|---|---|
| 1 | Primary | Pays 80% of $1,000 | $800 |
| 2 | Secondary | Pays remaining balance up to 100% of expense | $1,000 |
| 3 | Insured | Owes nothing beyond cost-sharing already applied | — |
The same anti-profit logic underlies the principle of indemnity throughout health insurance: the insured is made whole, never enriched.
Human Life Value and Needs Analysis — Worked Numerics
Because life insurance is a valued contract, producers use two recognized methods to recommend a reasonable face amount, and the exam tests both.
The human life value (HLV) approach values the insured's future earnings lost to premature death. Worked example: a 35-year-old earns $80,000, of which $20,000 covers personal expenses and taxes, leaving $60,000 of annual support for the family for 30 years to retirement. Ignoring discounting for simplicity, HLV is roughly $60,000 x 30 = $1,800,000 of economic value to insure.
The needs (capital-needs) analysis instead totals the family's actual cash needs and subtracts existing resources. Worked example: final expenses $15,000 + mortgage payoff $220,000 + an income fund of $600,000 + college fund $120,000 = $955,000 of need. Subtract existing assets and prior coverage of $255,000, and the recommended new coverage is $700,000.
The two methods often differ; HLV measures lost earnings, while needs analysis measures specific obligations. Recommending coverage grossly above either figure can raise suitability and over-insurance concerns.
A creditor lends a borrower $50,000 and insures the borrower's life. Two years later the loan is fully repaid, but the policy stays in force. The borrower dies. Regarding the death benefit, the creditor:
Life insurance is classified as a valued contract rather than a contract of indemnity because:
