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.
Rate of Return. Municipal bonds pay a fixed amount of interest each year. Called the coupon rate, this interest is a percentage of the par value of the bond. Par value is the amount the bond issuer pays when the bond matures, or comes due, in order to repay the borrowed money. Your actual rate of return, or yield, will be different than the coupon rate if you buy the bond for a price other than the par value. Suppose you buy a muni with a par value of $5,000 that pays $150 yearly or a 3 percent coupon rate, however, you pay only $4,000.
