Not all life insurance policies are underwritten, but because some are it is important to understand what it means. Underwriting is a term used by life insurers to describe the process of assessing risk, ensuring that the cost of the cover is proportionate to the risks faced by the individual concerned. People with the same or similar risk pay the same or similar premium rates.
In a group insurance setting, the underwriter must consider such things as the type of work being performed, the ages of the participants, and the probability of the particular group being an adverse risk to the insurance company.
