5.3 Life Insurance Underwriting and Risk Classification

Life Insurance Underwriting and Risk Classification

Underwriting is the process of evaluating, selecting, and classifying risk so that each insured pays a premium proportional to the expected mortality cost. The goal is adequate, equitable, and not unfairly discriminatory rates. Underwriters protect the insurer against adverse selection — the tendency of higher-risk applicants to seek (and lower-risk applicants to avoid) coverage.

Sources of Underwriting Information

• Application — the primary source; the basis of the contract once attached.
• Medical exam / paramedical exam — ordered based on age and face amount; includes blood and urine analysis.
• Attending Physician Statement (APS) — requested when the application or exam raises questions.
• MIB (Medical Information Bureau) — a member-funded clearinghouse of coded medical impairments. An MIB report can prompt further inquiry but may not be the sole basis for a declination.
• Inspection / consumer report — lifestyle, finances, and habits. The Fair Credit Reporting Act (FCRA) governs these reports: the applicant must be notified that a report may be ordered and has the right to know the nature and scope of an investigative consumer report.

Risk Classifications

After gathering information, the underwriter assigns the applicant a class that drives the premium rate:

A rated (substandard) policy charges more, usually through a table rating (each table adds roughly 25% to standard mortality) or a flat extra dollar amount per $1,000 of face for a defined or permanent period.

Worked example — table rating. Standard annual premium is $1,000. The applicant is rated Table 4, adding 25% per table (4 × 25% = 100% extra). The premium becomes $1,000 × (1 + 1.00) = $2,000 per year. At Table 2 it would be $1,000 × 1.50 = $1,500.

Insurable Interest and Other Principles

• Insurable interest must exist at the time of application (for life insurance), not necessarily at the time of loss. A person has insurable interest in their own life, a spouse, dependents, and a business has it in a key person or partner.
• STOLI / IOLI (stranger/investor-originated life insurance) is prohibited because there is no insurable interest at inception.
• HIV/genetic information — underwriting use is restricted; testing requires informed consent, results are confidential, and use must be actuarially justified and not unfairly discriminatory.

Selection Factors

Underwriters weigh physical condition (build, blood pressure, history), moral hazard (a tendency toward dishonesty or fraud), morale hazard (indifference to loss because one is insured), occupation, avocation (hobbies like skydiving), and financial justification (the face amount must be reasonable relative to income and need). A field underwriter — the producer — performs the first screen by completing a complete and accurate application.

Premium Components and AIDS Trap

The net premium equals mortality cost plus interest assumption; the gross premium adds the expense load (the "loading"). Mortality is drawn from a mortality table (such as the 2017 CSO table). Younger and healthier insureds cost less because expected mortality is lower.

Common exam traps:

• The MIB cannot be the sole reason to decline — it can only flag items for further investigation.
• Adverse underwriting based on a consumer report triggers an FCRA adverse-action notice to the applicant.
• Insurable interest for life insurance is required at application, not at death — this differs from property insurance, which requires it at the time of loss.

Numeric Risk and Field-Underwriting Documents

Larger insurers use a numerical rating system: a standard risk starts at 100% of expected mortality (the "100% to 125%" band is typically standard), and debits and credits are added for each impairment, build, family history, occupation, and habit. The total percentage maps to a class. For example, debits totaling 200% mean expected mortality is twice standard, roughly a Table 4 rating.

Worked example — debits and credits. A base of 100% receives +50% for a controlled cardiac condition, +25% for a hazardous avocation, and -10% credit for excellent build, for a net 165%. That falls in the substandard range and is rated to the corresponding table.

Three disclosures are tested repeatedly. The HIPAA / privacy authorization lets the insurer collect protected health information. The USA PATRIOT Act / anti-money-laundering (AML) training applies to producers selling cash-value products and annuities. The Notice of Information Practices under state privacy law and FCRA tells applicants what data is collected and their access rights. An applicant denied or rated up has the right to know the reason and the source of any consumer report used.

Finally, distinguish risk selection from rate equity. Underwriting selects which risks to insure and at what class, while actuaries set the rate tables for each class. A producer who knowingly omits a material health fact to secure a standard rate commits fraud, not underwriting — and the resulting policy can be rescinded during the contestable period, leaving the client with no coverage when it is needed most.

The Three Standard Risk Classes and Substandard Pricing

Life underwriting sorts applicants into preferred (better-than-average health/lifestyle, lowest premium), standard (average risk, standard premium), and substandard/rated (higher-than-average risk, surcharged premium). A declined applicant is uninsurable at any price. Substandard cases are priced by a table rating (each table adds a set percentage to the standard premium) or a flat extra (a fixed dollar add-on per $1,000, used for temporary or specific hazards). The exam tests that a rated policy charges more, not less, and may use either method.

Sources of Underwriting Information

Underwriters draw on the application, the medical exam/APS (attending physician statement), the MIB (Medical Information Bureau) report, inspection reports, and prescription and motor-vehicle databases. MIB data is a coded alert, not a basis for declination by itself; the insurer must verify independently. Adverse decisions based on a consumer report trigger FCRA disclosure duties to the applicant.
