1. Which bonds should Sporer expect to have the highest and the lowest credit ratings? What does the time-interest-earned number indicate about the probability of any of the bonds defaulting in the immediate future? Does the times-interest-earned of 5.4 apply to each bond or all of them?

2. Each bond has 20 years to maturity and is selling for its par value. What explains the differences in yields? Are these yields current yields or anticipated yields?

3. Since duration is one measure of price volatility, what is the duration of each bond? What assumptions must be made to answer this question? Why may duration have little applicability to some of the bonds, and which ones?

4. If, after one year, interest rates are essentially unchanged and the price of the stock remains in the doldrums at $8.50, what should be the price of each bond?

5. If, after five years have elapsed and interest rates have risen 2 percentage points (200 basis points) across the board, what should be the price of each bond? What assumptions must be made to answer this question?

6. If, after ten years have elapsed, interest rates have declined by 2 percentage points and the stock indexes have risen 9 percent annually, what should be the price of each bond? What assumptions must be made to answer this question?

7. Given prices in Question 6, what are the annualized returns on each bond? If Sporer believes that the situation in Question 6 is the most likely scenario, what course of action should he recommend today?
