Common stock $50 million 15%

6. Company versus Project Discount Rates. Geothermal™s WACC is 11.4 percent. Executive
Fruit™s WACC is 12.3 percent. Now Executive Fruit is considering an investment in geother-
mal power production. Should it discount project cash flows at 12.3 percent? Why or why
not?
7. Flotation Costs. A project costs $10 million and has NPV of $+2.5 million. The NPV is
computed by discounting at a WACC of 15 percent. Unfortunately, the $10 million invest-
ment will have to be raised by a stock issue. The issue would incur flotation costs of $1.2
million. Should the project be undertaken?



8. WACC. The common stock of Buildwell Conservation & Construction, Inc., has a beta of
Practice .80. The Treasury bill rate is 4 percent and the market risk premium is estimated at 8 per-
Problems cent. BCCI™s capital structure is 30 percent debt paying a 5 percent interest rate, and 70 per-
cent equity. What is BCCI™s cost of equity capital? Its WACC? Buildwell pays no taxes.
9. WACC and NPV. BCCI (see the previous problem) is evaluating a project with an internal
rate of return of 12 percent. Should it accept the project? If the project will generate a cash
flow of $100,000 a year for 7 years, what is the most BCCI should be willing to pay to ini-
tiate the project?
10. Calculating WACC. Find the WACC of William Tell Computers. The total book value of the
firm™s equity is $10 million; book value per share is $20. The stock sells for a price of $30
per share, and the cost of equity is 15 percent. The firm™s bonds have a par value of $5 mil-
lion and sell at a price of 110 percent of par. The yield to maturity on the bonds is 9 percent,
and the firm™s tax rate is 40 percent.
11. WACC. Nodebt, Inc., is a firm with all-equity financing. Its equity beta is .80. The Treasury
bill rate is 5 percent and the market risk premium is expected to be 10 percent. What is
Nodebt™s asset beta? What is Nodebt™s weighted-average cost of capital? The firm is exempt
from paying taxes.
12. Cost of Capital. A financial analyst at Dawn Chemical notes that the firm™s total interest
payments this year were $10 million while total debt outstanding was $80 million, and he
concludes that the cost of debt was 12.5 percent. What is wrong with this conclusion?
13. Cost of Equity. Bunkhouse Electronics is a recently incorporated firm that makes electronic
entertainment systems. Its earnings and dividends have been growing at a rate of 30 percent,

and the current dividend yield is 2 percent. Its beta is 1.2, the market risk premium is 8 per-
cent, and the risk-free rate is 4 percent.

a. Calculate two estimates of the firm™s cost of equity.
b. Which estimate seems more reasonable to you? Why?

14. Cost of Debt. Olympic Sports has two issues of debt outstanding. One is a 9 percent coupon
bond with a face value of $20 million, a maturity of 10 years, and a yield to maturity of 10
percent. The coupons are paid annually. The other bond issue has a maturity of 15 years, with
coupons also paid annually, and a coupon rate of 10 percent. The face value of the issue
is $25 million, and the issue sells for 92.8 percent of par value. The firm™s tax rate is 35
percent.

a. What is the before-tax cost of debt for Olympic?
b. What is Olympic™s after-tax cost of debt?

15. Capital Structure. Examine the following book-value balance sheet for University Prod-
ucts, Inc. What is the capital structure of the firm based on market values? The preferred
stock currently sells for $15 per share and the common stock for $20 per share. There are
one million common shares outstanding.

16. Calculating WACC. Turn back to University Products™s balance sheet from the previous
problem. If the preferred stock pays a dividend of $2 per share, the beta of the stock is .8,
the market risk premium is 10 percent, the risk-free rate is 6 percent, and the firm™s tax rate
is 40 percent, what is University™s weighted-average cost of capital?
17. Project Discount Rate. University Products is evaluating a new venture into home com-
puter systems (see problems 15 and 16). The internal rate of return on the new venture
is estimated at 13.4 percent. WACCs of firms in the personal computer industry tend to
average around 14 percent. Should the new project be pursued? Will University Products
make the correct decision if it discounts cash flows on the proposed venture at the firm™s
WACC?
18. Cost of Capital. The total market value of Okefenokee Real Estate Company is $6 million,
and the total value of its debt is $4 million. The treasurer estimates that the beta of the stock
currently is 1.5 and that the expected risk premium on the market is 10 percent. The Trea-
sury bill rate is 4 percent.

a. What is the required rate of return on Okefenokee stock?
b. What is the beta of the company™s existing portfolio of assets? The debt is perceived to
be virtually risk-free.

c. Estimate the weighted-average cost of capital assuming a tax rate of 40 percent.
d. Estimate the discount rate for an expansion of the company™s present business.
e. Suppose the company wants to diversify into the manufacture of rose-colored glasses.
The beta of optical manufacturers with no debt outstanding is 1.2. What is the required
rate of return on Okefenokee™s new venture?




19. Changes in Capital Structure. Look again at our calculation of Big Oil™s WACC. Suppose
Challenge Big Oil is excused from paying taxes. How would its WACC change? Now suppose Big Oil
Problems makes a large stock issue and uses the proceeds to pay off all its debt. How would the cost
of equity change?
20. Changes in Capital Structure. Refer again to problem 19. Suppose Big Oil starts from the
financing mix in Table 4.13, and then borrows an additional $200 million from the bank. It
then pays out a special $200 million dividend, leaving its assets and operations unchanged.
What happens to Big Oil™s WACC, still assuming it pays no taxes? What happens to the cost
of equity?
21. WACC and Taxes. “The after-tax cost of debt is lower when the firm™s tax rate is higher;
therefore, the WACC falls when the tax rate rises. Thus, with a lower discount rate, the firm
must be worth more if its tax rate is higher.” Explain why this argument is wrong.
22. Cost of Capital. An analyst at Dawn Chemical notes that its cost of debt is far below that
of equity. He concludes that it is important for the firm to maintain the ability to increase its
borrowing because if it cannot borrow, it will be forced to use more expensive equity to fi-
nance some projects. This might lead it to reject some projects that would have seemed at-
tractive if evaluated at the lower cost of debt. Comment on this reasoning.

We use Hot Rocks™s pretax return on debt because the company pays no taxes.

3 Compare the two income statements, one for Criss-cross Industries and the other for a firm
with identical EBIT but no debt in its capital structure. (All figures in millions.)

Criss-cross Firm with No Debt
EBIT $10.0 $10.0
Interest expense 2.0 0.0
Taxable income 8.0 10.0
Taxes owed 2.8 3.5
Net income 5.2 6.5
Total income accruing to debt & equity holders 7.2 6.5

Notice that Criss-cross pays $.7 million less in taxes than its debt-free counterpart. Ac-
cordingly, the total income available to debt plus equity holders is $.7 million higher.
4 For Hot Rocks,
WACC = [.56 — 9 — (1 “ .35)] + (.44 — 17) = 10.76%
For Burg Associates,
WACC = [.45 — 14 — (1 “ .35)] + (.55 — 20) = 15.1%
5 WACC measures the expected rate of return demanded by debt and equity investors in the
firm (plus a tax adjustment capturing the tax-deductibility of interest payments). Thus the
calculation must be based on what investors are actually paying for the firm™s debt and eq-
uity securities. In other words, it must be based on market values.
6 From the CAPM:
requity = rf + βequity (rm “ rf)
= 6% + 1.20(9%) = 16.8%
WACC = .3(1 “ .35) 8% + .7(16.8%) = 13.3%

7 Jo Ann™s boss is wrong. The ability to borrow at 8 percent does not mean that the cost of
capital is 8 percent. This analysis ignores the side effects of the borrowing, for example, that
at the higher indebtedness of the firm the equity will be riskier, and therefore the equity-
holders will demand a higher rate of return on their investment.

CONFIDENTIAL MEMORANDUM


DATE: January 15, 2000
TO: S.S.S. Management
FROM: Joe-Bob Brinepool, President
SUBJECT: Cost of Capital


This memo states and clarifies our company™s long-standing policy regarding hurdle rates
for capital investment decisions. There have been many recent questions, and some evident
confusion, on this matter.
Sea Shore Salt evaluates replacement and expansion investments by discounted cash flow.
The discount or hurdle rate is the company™s after-tax weighted-average cost of capital.
