1.2 Insurable Interest, Indemnity, and Adverse Selection

Insurable interest in life and health

Insurable interest means the policyowner must stand to suffer a genuine financial or emotional loss if the insured dies or becomes disabled. Without it, a policy is an illegal wager and is void from inception. This single doctrine separates lawful insurance from gambling.

The critical exam rule for life insurance is timing: insurable interest must exist at the time the policy is applied for, not at the time of the claim. Property insurance reverses this — interest must exist at the time of loss — but life insurance only requires it at inception.

Who has insurable interest in a life?

The law presumes insurable interest in certain relationships and requires it to be proven in others.

A frequent trap: a creditor may insure a debtor's life only up to the outstanding loan balance, not for an arbitrary large amount.

The principle of indemnity

Indemnity means restoring the insured to the same financial position held just before the loss — no better, no worse. Its purpose is to prevent profiting from insurance, which would create moral hazard.

Health insurance is largely a reimbursement (indemnity) contract: it pays actual covered medical expenses up to policy limits. Life insurance, by contrast, is a valued contract, paying a stated face amount regardless of the 'value' of the life lost, because a human life has no objective market price. Know which products are indemnity-based and which are valued.

A worked indemnity example

Suppose a major-medical plan has a $2,000 deductible and 80/20 coinsurance up to an out-of-pocket maximum. The insured incurs $12,000 in covered charges.

• Insured pays the first $2,000 (deductible).
• Remaining covered charges: $12,000 − $2,000 = $10,000.
• Plan pays 80 percent of $10,000 = $8,000; insured pays 20 percent = $2,000.
• Total insured cost: $2,000 + $2,000 = $4,000; insurer pays $8,000.

The insured is reimbursed only for real expense and never comes out ahead — that is indemnity in action. Once the out-of-pocket maximum is reached, the plan typically pays 100 percent of further covered charges.

Adverse selection

Adverse selection is the tendency of people with a higher-than-average likelihood of loss to seek insurance more aggressively than average risks. A person recently diagnosed with a serious illness has a powerful incentive to buy the largest health or life policy possible.

If insurers did nothing, the pool would fill with bad risks, claims would exceed premiums, and rates would spiral. Underwriting exists primarily to combat adverse selection by screening, classifying, and pricing risks appropriately — or declining them.

Tools that fight adverse selection

Insurers and regulators deploy several mechanisms; the exam links each tool to the problem it solves:

• Underwriting and medical questions — identify substandard risks before issue.
• Pre-existing condition provisions and probationary periods — limit claims that the applicant knew about but did not disclose.
• Waiting/elimination periods in disability income — discourage claims for trivial or already-existing conditions.
• Attained-age and guaranteed-issue limits — control who can enroll without evidence of insurability.
• Grace periods and reinstatement underwriting — keep healthy lives in the pool while re-screening lapsed ones.

When a question asks 'why does the insurer require a medical exam?', the deepest correct answer is to prevent adverse selection.

Stranger-originated life insurance (STOLI)

A modern application of insurable interest is the prohibition on stranger-originated life insurance (STOLI), arrangements where investors with no genuine interest induce a senior to take out a policy intending to acquire it for speculation. Because the investors lack insurable interest at inception, such schemes are void as illegal wagers and are explicitly barred in most states.

The exam tests this as the logical extension of the insurable-interest doctrine: you cannot manufacture interest after the fact, and a policy that begins as a bet cannot be cured by later assigning it.

Subrogation and the prohibition on double recovery

Flowing from indemnity is the doctrine of subrogation: after an indemnity (health) insurer pays a covered loss caused by a third party, it may step into the insured's shoes to recover from that party. This prevents the insured from collecting twice — once from the insurer and again from the at-fault party — which would violate indemnity by producing a profit.

Subrogation applies to reimbursement coverages, not to life insurance, because a valued life contract pays a fixed face amount rather than reimbursing a measurable loss; there is no excess recovery to claw back.

Stop-loss and the out-of-pocket maximum

Returning to the indemnity example, the out-of-pocket maximum (a stop-loss feature) caps total insured cost-sharing for the year. Suppose that plan's out-of-pocket maximum is $5,000. Once the insured's combined deductible and coinsurance reach $5,000, the plan pays 100 percent of further covered charges.

In the worked case the insured had reached $4,000, so the next $1,000 of cost-sharing would still apply; beyond that, the insurer absorbs everything covered. This protects the indemnity principle from becoming ruinous to the insured while still preventing any profit.
