2- Airborne Airlines Inc. has a $1,000 par value bond outstanding with 10 years to maturity. The bond carries an annual interest payment of $84 and is currently selling for $890. Airborne is in a 30 percent tax bracket. The firm wishes to know what the aftertax cost of a new bond issue is likely to be.

3- The Nolan Corporation finds it is necessary to determine its marginal cost of capital. Nolan's current capital structure calls for 45 percent debt, 15 percent preferred stock, and 40 percent common equity.

The costs of the various sources of financing are as follows: debt, 8.2 percent; preferred stock, 6 percent; retained earnings, 15 percent; and new common stock, 16.2 percent.

b.If the firm has $30 million in retained earnings, at what size capital structure will the firm run out of retained earnings?(Enter your answer in millions of dollars (e.g., $10 million should be entered as "10").)

Capital structure size (X)_________ million

c.What will the marginal cost of capital be immediately after that point? (Equity will remain at 40 percent of the capital structure, but will all be in the form of new common stock,K_n.)(Do not round intermediate calculations. Input your answer as a percent rounded to 2 decimal places.)

Marginal cost of capital__________%

d.The 8.2 percent cost of debt referred to earlier applies only to the first $54 million of debt. After that, the cost of debt will be 9.5 percent. At what size capital structure will there be a change in the cost of debt?(Enter your answer in millions of dollars (e.g., $10 million should be entered as "10").)

Capital structure size (Z)_________ million

e.What will the marginal cost of capital be immediately after that point? (Consider the facts in both partscandd.)(Do not round intermediate calculations. Input your answer as a percent rounded to 2 decimal places.)

Marginal cost of capital__________%
