Best Efforts

An agreement between an underwriter and an issuer in which the underwriter agrees to place as much of an offering with investors as possible, but is not responsible for any portion of the offering it fails to sell. For example, suppose an issuer makes a new issue of 100,000 shares. The issuer may make a best effort agreement with an underwriting firm for the underwriter to sell those shares to investors. If the underwriting firm only sells 90,000, however, it is not required to buy the remaining 10,000 from the issuer. This reduces the risk to the underwriter; to reduce the risk to the issuer, most best efforts are all-or-none offerings.
