Definitions:

A fixed-rate bond will sell at par when its coupon interest rate is equal to the going rate of interest, rd. When the going rate of interest is above the coupon rate, a fixed rate bond will sell at a “discount” below its par value. If current interest rates are below the coupon rate, a fixed rate bond will sell at a “premium” above its par value.
