Problems and Questions

1. Rubberman Corporation, a manufacturer of consumer plastic products, is evaluating its capital structure. The balance sheet of the company is as follows (in millions):

Assets Liabilities

Fixed Assets 4000 Debt 2500

Current Assets 1000 Equity 2500

In addition, you are provided the following information:

(a) The debt is in the form of long term bonds, with a coupon rate of 10%. The bonds are currently rated AA and are selling at a yield of 12% (the market value of the bonds is 80% of the face value).

(b) The firm currently has 50 million shares outstanding, and the current market price is $80 per share. The firm pays a dividend of $4 per share and has a price/earnings ratio of 10.

(c) The stock currently has a beta of 1.2. The six-month Treasury bill rate is 8%.

(d) The tax rate for this firm is 40%.

I. What is the debt/equity ratio for this firm in book value terms? in market value terms?

II. What is the debt/(debt+equity) ratio for this firm in book value terms? in market value terms?

III. What is the firm's after-tax cost of debt?

IV. What is the firm's cost of equity?

V. What is the firm's current cost of capital?

2. Now assume that Rubberman Corporation is considering a project that requires an initial investment of $100 million and has the following projected income statement:

EBIT $20 million

- Interest $ 4 million

EBT $16 million

Taxes $ 6.40 million

Net Income $ 9.60 million

(Depreciation for the project is expected to be $5 million a year forever.)

This project is going to be financed at the same debt/equity ratio as the overall firm and is expected to last forever. Assume that there are no principal repayments on the debt (it too is perpetual).

I. Evaluate this project from the equity investors' standpoint. Does it make sense?

II. Evaluate this project from the firm's standpoint. Does it make sense?

III. In general, when would you use the cost of equity as your discount rate/benchmark?

IV. In general, when would you use the cost of capital as your benchmark?

V. Assume, for economies of scale, that this project is going to be financed entirely with debt. What would you use as your cost of capital for evaluating this project?

3. Rubberman is considering a major change in its capital structure. It has three options:

Option 1: Issue $1 billion in new stock and repurchase half of its outstanding debt. This will make it a AAA rated firm (AAA rated debt is yielding 11% in the market place).

Option 2: Issue $1 billion in new debt and buy back stock. This will drop its rating to A-. (A- rated debt is yielding 13% in the market place).

Option 3: Issue $3 billion in new debt and buy back stock. This will drop its rating to CCC (CCC rated debt is yielding 18% in the market place).

I. What is the cost of equity under each option?

II. What is the after-tax cost of debt under each option?

III. What is the cost of capital under each option?

IV. What would happen to (a) the value of the firm; (b) the value of debt and equity; and (c) the stock price under each option , if you assume rational stockholders?

V. From a cost of capital standpoint, which of the three options would you pick, or would you stay at your current capital structure?

VI. What role (if any) would the variability in XYZ's income play in your decision?

VII. How would your analysis change (if at all) if the money under the three options listed above were used to take new investments (instead of repurchasing debt or equity)?

VIII. What other considerations (besides minimizing the cost of capital) would you bring to bear on your decision?

IX. Intuitively, why doesnÌt the higher rating in option 1 translate into a lower cost of capital?

4. Rubberman Corporation is interested in how it compares with its competitors in the same industry.

XYZ Corporation Other Competitors

Debt/Equity Ratio 50% 25%

Variance in EBITDA 20% 40%

EBITDA/MV of Firm 25% 15%

Tax Rate 40% 30%

R&D/ Sales 2% 5%

a. Taking each of these variables, explain at an intuitive level whether you would expect XYZ Corporation to have more more or less debt than its competitors and why.

b. You have also run a regression of debt/equity ratios against these variables for all the firms on the New York Stock Exchange and have come up with the following regression equation:

D/E = .10 - .5 (Variance in EBITDA) + 2.0 (EBITDA/MV) + .4 (Tax rate) + 2.5 (R&D/Sales)

(All inputs to the regression were in decimals, i.e. 20% was inputted as .20 ....)

Given this cross-sectional relationship, what would you expect XYZ's debt/equity ratio to be?

5. As CEO of a major corporation, you have to make a decision on how much you can afford to borrow. You currently have 10 million shares outstanding, and the market price per share is $50. You also currently have about $200 million in debt outstanding (market value). You are rated as a BBB corporation now.

(a) Your stock has a beta of 1.5 and the six-month T.Bill rate is 8%.

(b) Your marginal tax rate is 46%.

(c) You estimate that your rating will change to a B if you borrow $100 million. The BBB rate now is 11%. The B rate is 12.5%.

I. Given the marginal costs and benefits of borrowing the $100 million, should you go ahead with it ?

II. What is your best estimate of the weighted average cost of capital with and without the $100 million in borrowing ?

III. If you borrow the $100 million, what will the price per share be after the borrowing

IV. Assume that you have a project that requires an investment of $100 million. It has expected before-tax revenues of $50 million, and costs of $30 million a year in perpetuity. Is this a desirable project by your criteria? Why or Why not?

V. Does it make a difference in your decision if you were told that the cash flows from the project in (IV) are certain?

6. You have been hired as a management consultant by AD Corporation to evaluate whether it has an appropriate amount of debt (the company is worried about a leveraged buyout). You have collected the following information on AD's current position:

(a) There are 100,000 shares outstanding, at $20/share. The stock has a beta of 1.15.

(b) The company has $500,000 in long-term debt outstanding and is currently rated 'BBB'. The current market interest rate is 10% on BBB bonds and 6% on T.Bills.

(c) The company's marginal tax rate is 40%.

You proceed to collect the data on what increasing debt will do to the company's ratings:
Additional debt* New Rating Interest Rate
$500,000 BB 10.5
$1,000,000 B 11.5
$1,500,000 B-13.5
$2,000,000 C 15

* In addition to the existing debt of $500,000

I. How much additional debt should the company take on?

II. What will the price per share be after the company takes on new debt?

III. What is the weighted average cost of capital before and after the additional debt?

IV. Assume that you are considering a project that has the following earnings in perpetuity and is of comparable risk to existing projects.
Revenues/year $1,000,000
Cost of goods sold $ 400,000 (Includes depreciation of $100,000)
EBIT $ 600,000
Debt payments$ 100,000 (All Interest payments)
Taxable Income $ 500,000
Tax $ 200,000
After-tax profit $ 300,000

If this project requires an investment of $ 3,000,000, what is its NPV?

25. XCV Inc., which manufactures automobile parts for assembly, is considering the costs and the benefits of leverage. The CFO notes that the return on equity of the firm, which is only 12.75% now, based upon the current policy of no leverage, could be increased substantially by borrowing money. Is this true? Does it follow that the value of the firm will increase with leverage? Why or why not?
