What Is Underwriting?

The process by which an investment bank or securities firm agrees to purchase new securities from an issuer and sell them to the public, bearing the risk of any unsold inventory. In firm commitment underwriting, the underwriter buys all securities upfront; in best efforts, it sells as much as it can. Underwriters earn fees and potential profit from the spread between acquisition and selling prices.
