Problem 11-31 The Nolan Corporation finds that it is necessary to determine its marginal cost of capital. Nolan's current capital structure calls for 30 percent debt, 30 percent preferred stock, and 40 percent common equity, Initially common equity will be in the form of retained earnings (X.) and then new common stock (Kn). The costs of the various sources of financing are as follows: debt, 8.5 percent preferred stock, 6 percent; retained earnings, 12 percent; and new common stock, 13.2 percent. a. What is the initial weighted average cost of capital? (Include debt, preferred stock, and common equity in the form of retained earnings.xa) (Do not round intermediate calculations. Round the final answer to 2 decimal places.) Weighted average cost of capital ]% b. If the firm has $18 million in retained earnings, at what size of investment will the firm run out of retained earnings? (Enter the answer in millions.) 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 it will all be in the form of new common stock, n) (Do not round intermediate calculations. Round the final answer to 2 decimal places) Marginal cost of capital d. The 8.5 percent cost of debt referred to above applies only to the first $24 million of debt. After that the cost of debt will be 10.5 percent. At what size of investment will there be a change in the cost of debt? (Enter the answer in millions.) Capital structure size (2) million e. What will the marginal cost of capital be immediately after that point? (Consider the facts in both parts cand d) (Do not round Intermediate calculations. Round the final answer to 2 decimal places.) Marginal cost of capital Help Save Problem 11-28 (calculator version) McNabb Construction Company is trying to calculate its cost of capital for use in making a capital budgeting decision. Mt. Reid, the vice-president of finance, has given you the following information and has asked you to compute the weighted average cost of capital The company currently has an outstanding bond with a 5.2 percent coupon rate and another bond with a 74 percent rate. The firm has been informed by its investment dealer that bonds of equal risk and credit ratings are now selling to yield 8.6 percent. The common stock has a price of $99.20 and an expected dividend (D) of $5.15 per share. The historical growth pattern (g) for dividends is as follows: $4.00 4.24 4.51 4.81 The preferred stock is selling at $90 per share and pays a dividend of $8.50 per share. The corporate tax rate is 30 percent. The flotation cost is 2.6 percent of the selling price for preferred stock. The optimum capital structure for the firm is 15 percent debt, 10 percent preferred stock, and 75 percent common equity in the form of retained earnings. a. Compute the historical growth rate. (Round intermediate calculations to 2 decimal places. Round the final to 2 decimal places.) Growth rate b. Compute the cost of capital for the individual components in the capital structure.
