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.
Securities underwriting refers to the process by which investment banks raise investment capital from investors on behalf of corporations and governments that are issuing securities (both equity and debt capital). The services of an underwriter are typically used during a public offering in a primary market.
