Underwriting

The process an insurer uses to evaluate an applicant's risk, from health and lifestyle to finances, and decide whether and at what price to offer coverage.

Also called: life insurance underwriting, medical underwriting

Underwriting is how a life insurer decides whether to accept an application and what to charge. It protects the insurer from adverse selection, the tendency of people at higher risk to seek more coverage, and sorts applicants into rate classes so each group pays for its expected risk.

There are several levels. Full medical underwriting may include a paramedical exam, blood and urine tests, records from your doctors and database checks. Accelerated underwriting uses data such as prescription history, MIB reports, motor vehicle records and sometimes credit-based scores to approve healthy applicants without an exam. simplified issue coverage relies on a short health questionnaire, and guaranteed issue skips health questions entirely in exchange for lower limits and higher prices. Hypothetically, a healthy 30-year-old applying for $500,000 online might be approved in minutes through accelerated underwriting, while a 60-year-old applying for $3 million might wait several weeks for exams, records and a financial review.

Underwriters weigh age, health, family history, build, tobacco use, driving record, occupation, hobbies, travel and finances. Honesty on the application matters: misstatements can be grounds for rescinding coverage during the contestable period.
