Under rules governing municipal bonds, callable premium bonds must be priced to the date resulting in the worst (lowest) yield for the investor. Generally this means that the bonds are priced to the first call date. This is attractive to investors because, in the event the bonds are not called, the yield to maturity will be much higher. Furthermore, in a rising rate environment, premium bonds retain their value better than par or discount bonds.
An unsecured bond or debenture is backed by the full faith and credit of the issuer, but not by any specific collateral. 1  Corporate bonds are issued by corporations and are rated according to their quality. Corporate bonds typically pay higher interest rates than municipal or government bonds. Municipal bonds are issued by state, city and local municipalities. Municipal bond income is free from federal income taxes and may be exempt from state taxes when issued in the bondholder's state of residence.
