Final answer:
The call premium is the amount by which the call price of a bond exceeds its par value. It serves as compensation to bondholders when the bond is called before maturity, reflecting the risk of reinvestment at potentially lower interest rates.
Step-by-step explanation:
The call premium is the amount by which the call price exceeds the par value of a bond. This premium is an additional amount that investors receive over the bond's par value when the issuing company decides to call the bond before its maturity date. For instance, if a bond with a par value of $1,000 is callable at $1,050, the call premium is $50. The existence of a call premium is often viewed as a compensation to the bondholders for the reinvestment risk associated with having their bonds called before maturity, especially when interest rates decline, and they cannot reinvest at the same rate.
In the provided background information, we've seen how changes in prevailing interest rates can affect the market price of bonds. If interest rates rise, the market price of the existing bonds tend to fall below their face value because new bonds would likely be issued at higher rates, making the older (lower-rate) bonds less attractive. Similarly, if interest rates fall, existing bonds with higher interest rates become more valuable, and their market prices can rise above the face value. This relationship demonstrates the inherent risks and valuation adjustments that occur in the fixed-income market.
