The yield on a security sold at a discount. U.S. treasury bills are sold at a discount. The face amount is returned to the investor at maturity. The annual yield is computed by dividing the discount by the face amount, then multiplying by the number of days in the year (360) and dividing by the number of days to maturity. For example, a note purchased for $950 that returns $1,000 at maturity 11 months later. The note pays no interest; instead, your entire return is determined by the amount of the discount ($50 in this example). Banker's acceptances, commercial paper, and other short-term instruments frequently use this approach to compensate the buyer.
