Call premium

A call premium is the excess amount over the par value of a bond that the issuer is willing to pay in order to redeem a bond before its maturity date. Depending on the terms of the bond agreement, the call premium usually declines as the current date approaches the maturity date. This premium is intended to compensate investors for the loss of income if a bond they hold is redeemed, and they have to reinvest the funds at a lower interest rate.

A bond issuer usually redeems bonds when the interest rate has dropped to such an extent that it is worth the cost of paying the call premium in order to pay the lower rate on a replacement bond.
