5.3 Life Insurance Underwriting and Risk Classification

The purpose of underwriting

Underwriting is the process of evaluating, selecting, and classifying risks so that the premium charged is proportionate to the exposure assumed. Its central job is to control adverse selection — the tendency of higher-risk applicants to seek coverage more aggressively than lower-risk applicants. If underwriting failed, healthy insureds would subsidize unhealthy ones and the risk pool would deteriorate.

Underwriters apply the concept of the standard risk as a benchmark and then classify each applicant relative to it.

Risk classifications

A substandard (rated) applicant may be charged an extra (flat) premium, given a table rating (e.g., Table 2 = 150% of standard mortality, with each table adding ~25%), or issued with an impairment rider excluding a specific cause of loss.

Classification rests on three controllable variables the underwriter can adjust: the premium charged, the amount of coverage offered, and the policy form or rider applied. By altering one or more, the underwriter can convert a borderline applicant from a decline into an issuable risk — for example, offering a lower face amount or attaching an aviation-exclusion rider instead of declining outright.

Sources of underwriting information

Underwriters gather information from several regulated sources:

• The application — the primary source; Part I (general/personal data) and Part II (medical history).
• Medical exam / paramedical exam — required above certain ages or face amounts; may include blood, urine, and an attending physician's statement (APS).
• Attending Physician's Statement (APS) — obtained, with the applicant's written authorization, when medical history needs clarification.
• MIB (Medical Information Bureau) — a member-insurer database of coded prior impairments. An insurer may not decline or rate an applicant solely on an MIB report; it must independently verify the underlying condition.
• Inspection report / Investigative Consumer Report (ICR) — third-party report on lifestyle, finances, and reputation, governed by the Fair Credit Reporting Act (FCRA).
• MVR (Motor Vehicle Report) for driving history.

FCRA disclosure requirements

Under FCRA, if an investigative consumer report may be used, the applicant must receive advance written notice and the right to request the nature and scope of the investigation. If coverage is declined or rated because of such a report, the insurer must inform the applicant and identify the reporting agency (adverse action notice).

Risk factors evaluated

Underwriters weigh physical condition, medical history, occupation, hobbies/avocations (e.g., scuba, aviation), habits (tobacco/alcohol), moral hazard, and financial justification. Financial underwriting confirms that the face amount is reasonable relative to income and need, preventing speculation.

Worked numerics: rating a substandard risk

A flat extra premium adds a fixed dollar amount per $1,000 of face. Example: a standard premium is $12 per $1,000 and the underwriter adds a $3 per $1,000 flat extra for a hazardous occupation. On a $150,000 policy:

• Standard annual premium = 150 units x $12 = $1,800
• Flat extra = 150 units x $3 = $450
• Total annual premium = $2,250

Table ratings instead multiply mortality. If standard is $1,800 and the applicant is Table 4 (each table ≈ +25%, so Table 4 ≈ 200% of standard mortality cost portion), the mortality component is roughly doubled. Candidates should know the direction and mechanism (flat extra = fixed add-on; table rating = percentage multiple) rather than a single carrier's exact factors.

A flat extra premium is best for a temporary hazard that diminishes over time (a dangerous hobby the applicant may abandon) because it can be removed later; a table rating is used for a permanent mortality impairment (chronic disease) that scales with the death benefit. An impairment (exclusion) rider is used when one specific cause — say, a pre-existing back condition or aviation — drives the excess risk, allowing standard rates for everything else.

Exam trap: An insurer cannot reject or rate an applicant based only on an MIB code; MIB is a tip, not proof. Also, MIB reports impairments by code — it does not store full medical records.

The Three Standard Risk Classes — And Their Pricing Effect

A substandard risk is priced up using a table rating (e.g., Table 2 = standard +50%) or a flat extra (a fixed dollar charge per $1,000 for a temporary hazard such as a dangerous hobby). The exam may ask which method handles a temporary extra risk — that is the flat extra.

Sources of Underwriting Information

The underwriter assembles data from the application, the attending physician's statement (APS), paramedical/medical exams, the MIB (Medical Information Bureau) — a member-shared database that flags prior conditions but is never the sole basis for declination — and inspection reports for lifestyle and financial detail.

Exam Distinction: Information that increases mortality risk is a hazard; the MIB only codes impairments reported by member companies and cannot, by law, be the sole reason to decline an applicant. Any adverse action taken from a consumer report triggers a notice under the Fair Credit Reporting Act.
