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.
Issuers that meet certain credit criteria can purchase municipal bond insurance policies from private companies. The insurance guarantees the payment of principal and interest on a bond issue if the issuer defaults.istorically, bond insurance is purchased through a one time payment of a premium at the time of the bond closing. (Depending on the issue BAM may have both upfront and annual premiums.) Not all issues qualify for insurance.
