Chapter 05: Bonds, Bond Valuation, and Interest Rates
71. Suppose International Digital Technologies decides to raise a total of $200 million, with $100 million as long-term
debt and $100 million as common equity. The debt can be mortgage bonds or debentures, but by an iron-clad provision in
its charter, the company can never raise any additional debt beyond the original $100 million. Given these conditions,
which of the following statements is CORRECT?
a. If the debt were raised by issuing $50 million of debentures and $50 million of first mortgage bonds, we could be
certain that the firm’s total interest expense would be lower than if the debt were raised by issuing $100 million of
debentures.
b. In this situation, we cannot tell for sure how, or whether, the firm’s total interest expense on the $100 million of
debt would be affected by the mix of debentures versus first mortgage bonds. The interest rate on each of the two types of
bonds would increase as the percentage of mortgage bonds used was increased, but the result might well be such that the
firm’s total interest charges would not be affected materially by the mix between the two.
c. The higher the percentage of debentures, the greater the risk borne by each debenture, and thus the higher the
required rate of return on the debentures.
d. If the debt were raised by issuing $50 million of debentures and $50 million of first mortgage bonds, we could be
certain that the firm’s total interest expense would be lower than if the debt were raised by issuing $100 million of first
mortgage bonds.
e. The higher the percentage of debt represented by mortgage bonds, the riskier both types of bonds will be and,
consequently, the higher the firm’s total dollar interest charges will be.
72. If 10-year T-bonds have a yield of 6.2%, 10-year corporate bonds yield 8.5%, the maturity risk premium on all 10-
year bonds is 1.3%, and corporate bonds have a 0.4% liquidity premium versus a zero liquidity premium for T-bonds,
what is the default risk premium on the corporate bond?
