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.
Yield to maturity (YTM). Yield to maturity is the most precise measure of a bond's anticipated return and determines its current market price. YTM takes into account the coupon rate and the current interest rate in relation to the price, the purchase or discount price in relation to the par value, and the years remaining until the bond matures.
