evaluate the risk and exposures of potential clients.
They decide how much coverage the client should receive, how much they should pay for it, or whether even to accept the risk and insure them.
Underwriting involves measuring risk exposure and determining the premium that needs to be charged to insure that risk. The function of the underwriter is to acquire—or to "write"—business that will make the insurance company money, and to protect the company's book of business from risks that they feel will make a loss. In simple terms, it is the process of issuing insurance policies. Each insurance company has its own set of underwriting guidelines to help the underwriter determine whether or not the company should accept the risk. The information used to evaluate the risk of an applicant for insurance will depend on the type of coverage involved.
For example, in medical underwriting may be used to examine the applicant's health status (other factors may be considered as well, such as age & occupation). The factors that insurers use to classify risks should be objective, clearly related to the likely cost of providing coverage, practical to administer, consistent with applicable law, and designed to protect the long-term viability of the insurance program.[1] The underwriters may either decline the risk or may provide a quotation in which the premiums have been loaded or in which various exclusions have been stipulated, which restrict the circumstances under which a claim would be paid. Depending on the type of insurance product (line of business), insurance companies use automated underwriting systems to encode these rules, and reduce the amount of manual work in processing quotations and policy issuance. This is especially the case for certain simpler life or personal lines (auto, homeowners) insurance.
