Best-efforts sale - A method of securities distribution/underwriting in which the securities firm agrees to sell as much of the offering as possible and return any unsold shares to the issuer. As opposed to a guaranteed or fixed price sale, where the underwriter agrees to sell a specific number of shares (with the securities firm holding any unsold shares in its own account if necessary).
