8.1 Underwriting Process, Risk Classification, and MIB

What Underwriting Is

Underwriting is the process of evaluating an applicant's risk, deciding whether to insure, and setting the premium that fairly reflects that risk. The underwriter's central enemy is adverse selection — the tendency of people who expect to need coverage soon to seek it most aggressively.

If an insurer charged everyone the same rate, healthy applicants would leave for cheaper carriers and only high-risk people would stay, driving claims above premiums. Underwriting solves this by sorting applicants into priced classes.

Three people share underwriting duties. The field underwriter is the producer, who gathers honest answers and reports observations. The home-office underwriter makes the final risk decision. The applicant supplies truthful information. A producer who knowingly omits a material fact commits concealment and exposes the carrier to a claim it never priced.

Risk Classifications

Applicants are placed into classes by expected mortality relative to the standard population.

A preferred life is healthier than average and pays less than standard. A substandard life is rated. Tobacco use typically forces a separate tobacco class — a smoker often pays roughly two to three times a non-smoker's rate at the same age.

Rating a Substandard Risk

When an applicant is worse than standard, the underwriter prices the extra mortality two ways.

Table rating multiplies the standard premium by a fixed step. Each table (A, B, C... or 1, 2, 3...) usually adds about 25 percentage points above standard.

Worked example: A standard annual premium is $800. A Table C (3) rating adds 75%, so the rated premium is $800 × 1.75 = $1,400.

A flat extra premium instead adds a fixed dollar amount per $1,000 of face for a specific, often temporary, hazard (a dangerous hobby, an aviation risk). Example: a $1.50 flat extra per $1,000 on a $250,000 policy adds 250 × $1.50 = $375 per year, and may be removed when the hazard ends. Underwriters may also attach an exclusion rider that simply removes coverage for a named cause.

Sources of Underwriting Information

The application is the primary source and the foundation of the contract. Part 1 collects identity, occupation, income, and other coverage; Part 2 collects medical history. The producer adds an agent's (producer's) report of personal observations.

When more data is needed, the carrier draws on:

• Paramedical exam — height, weight, blood pressure, plus blood and urine specimens (no full physician physical).
• Attending Physician Statement (APS) — records pulled directly from the applicant's own doctor; the most authoritative medical source but slow.
• Inspection report — third-party lifestyle and financial check; a Motor Vehicle Report (MVR) for driving history.
• Prescription (Rx) database — reveals medications that hint at undisclosed conditions.

Exam trap: An APS is requested from the applicant's physician; the applicant does not write it.

The Medical Information Bureau (MIB)

The Medical Information Bureau (MIB) is a nonprofit clearinghouse used by most U.S. life insurers. Member companies report coded impairments — brief symbols, not narrative records, lab values, or claim data.

The MIB exists to catch omissions, not to make decisions. If a coded entry conflicts with the application, the underwriter must verify it through an independent source before acting.

Consumer Protection: the FCRA

Inspection and credit reports are consumer reports under the federal Fair Credit Reporting Act (FCRA).

• The applicant must receive advance notice that a report may be ordered.
• An investigative consumer report (interviews with neighbors or associates) requires additional disclosure.
• If the report causes an adverse action (decline, rating, or reduced offer), the insurer must send an adverse-action notice identifying the reporting agency and the applicant's right to a free copy and to dispute it.

Memory hook: MIB → medical, coded, can only flag. FCRA → third-party reports, requires notice + adverse-action disclosure.

Stranger-Originated and Insurable Interest

Underwriting also confirms insurable interest existed at issue — the policy owner must have suffered a genuine loss from the insured's death (family bond or financial dependence). A policy taken out by investors with no such interest is a Stranger-Originated Life Insurance (STOLI) arrangement, which is unlawful and a reason to decline. Insurable interest must exist at the time the policy is issued; it need not continue until the claim, which is why an ex-spouse named long ago can still collect.
