The cost of capital depends on the risk of the projec

Here, the appropriate discount rate is 9.4%. d. requity = rf + (rm rf) = 0.04 + (1.2 0.06) = 0.112 = 11.2% 0.112$10million$6mil

The R2 value for BP was 0.27, which means that 27% of total risk comes from movements in the market (i.e.,
5、market risk). Therefore, 73% of total risk is unique risk. The R2 value for British Airways was 0.37, which means that 37% of total risk comes from movements in the market (i.e., market risk). Therefore, 63% of total risk is unique risk. b. The variance of BP is: (25)2 = 625 Market risk for BP: 0.27
6、 625 = 168.75 Unique risk for BP: 0.73 625 = 456.25 c. The t-statistic for BA is: 2.12/0.37 = 5.73 This is significant at the 1% level, so that the confidence level is 99%. d. rBA = rf + BA (rm rf) = 0.05 + 2.12 (0.12 0.05) = 0.1984 = 19.84% e. rBA = rf + BA (rm rf) = 0.05 + 2.12 (0 0.05) = 0.0560 =
7、 5.60% 6. Internet exercise; answers will vary. 7. The total market value of outstanding debt is 100 million. The cost of debt capital is 7.5 percent. For the common stock, the outstanding market value is: 40 2 million = 80 million. The cost of equity capital is 11 percent. Thus, Loreleis weighted-a
8、verage cost of capital is: 0.1180million100million80million0.07580million100million100millionrassets rassets = 0.0906 = 9.06% 8. a. rBN = rf + BN (rm rf) = 0.035 + (0.53 0.08) = 0.0774 = 7.74% rIND = rf + IND (rm rf) = 0.035 + (0.49 0.08) = 0.0742 = 7.42% b. No, we can not be confident that Burlingt
9、ons true beta is not the industry average. The difference between BN and IND (0.04) is less than one standard error (0.20), so we cannot reject the hypothesis that BN = IND. 74 c. Burlingtons beta might be different from the industry beta for a variety of reasons. For example, Burlingtons business m
10、ight be more cyclical than is the case for the typical firm in the industry. Or Burlington might have more fixed operating costs, so that operating leverage is higher. Another possibility is that Burlington has more debt than is typical for the industry so that it has higher financial leverage. 9. a
11、. The threat of a coup dtat means that the expected cash flow is less than $NZ900 million. The threat could also increase the discount rate, but only if it increases market risk. b. If New Zealand Marine proceeds with the construction of the supply submarine and the Republic then fails to make the f
12、inal $NZ900 million payment, then New Zealand Marine can sell the submarine to another buyer for $NZ600 million. Therefore, the expected cash flow for the year 2 payment is: (0.20 $NZ600 million) + (0.80 $NZ900 million) = $NZ840 million Assume that New Zealand Marines costs are incurred equally in Y
13、ear 0, Year 1 and Year 2, and that the cash flows are about as risky as the rest of the companys business. Then: PV = 400 + 500 + ( 400/1.10) + ( 400 + 840)/1.102 = +100 or $NZ100 million 10. a. If you agree to the fixed price contract, operating leverage increases. Changes in revenue result in grea
14、ter than proportionate changes in profit. If all costs are variable, then changes in revenue result in proportionate changes in profit. Business risk, measured by assets, also increases as a result of the fixed price contract. If fixed costs equal zero, then: assets = revenue. However, as PV(fixed c
15、ost) increases, assets increases. b. With the fixed price contract: PV(assets) = PV(revenue) PV(fixed cost) PV(variable cost) 9(1.09)(0.09)$10million)6%,10years factorannuity $10million0.09$20millionPV(assets)( PV(assets) = $97,462,710 Without the fixed price contract: PV(assets) = PV(revenue) PV(va

Expected daily production = (0.2 0) + 0.8 (0.4 x 1,000) + (0.6 x 5,000) = 2,720 barrels Expected annual cash revenues = 2,720 x 365 x $15 = $14,892,000 b. The possibility of a dry hole is a diversifiable risk and should not
17、 affect the discount rate. This possibility should affect forecasted cash flows, however. See Part (a). 12.

18、.04 0.5 2.02 The betas increase compared to those reported in Table 9.2 because the returns for these markets are now more highly correlated with the U.S. market. Thus, the contribution to overall market risk becomes greater. 13. The information could be helpful to a U.S. company considering interna
19、tional capital investment projects. By examining the beta estimates, such companies can evaluate the contribution to risk of the potential cash flows. A German company would not find this information useful. The relevant risk depends on the beta of the country relative to the portfolio held by inves
20、tors. German investors do not invest exclusively, or even primarily, in U.S. company stocks. They invest the major portion of their portfolios in German company stocks. 74 14. The opportunity cost of capital is given by: r = rf + (rm rf) = 0.05 + (1.2 0.06) = 0.122 = 12.2% Therefore: CEQ1 = 150(1.05
21、/1.122) = 140.37 CEQ2 = 150(1.05/1.122)2 = 131.37 CEQ3 = 150(1.05/1.122)3 = 122.94 CEQ4 = 150(1.05/1.122)4 = 115.05 CEQ5 = 150(1.05/1.122)5 = 107.67 a1 = 140.37/150 = 0.9358 a2 = 131.37/150 = 0.8758 a3 = 122.94/150 = 0.8196 a4 = 115.05/150 = 0.7670 a5 = 107.67/150 = 0.7178 From this, we can see that
22、 the a t values decline by a constant proportion each year: a2/a1 = 0.8758/0.9358 = 0.9358 a3/a2 = 0.8196/0.8758 = 0.9358 a4/a3 = 0.7670/0.8196 = 0.9358 a5/a4 = 0.7178/0.7670 = 0.9358 15. a. Using the Security Market Line, we find the cost of capital: r = 0.07 + 1.5 (0.16 0.07) = 0.205 = 20.5% There
23、fore: b. CEQ1 = 40(1.07/1.205) = 35.52 CEQ2 = 60(1.07/1.205)2 = 47.31 CEQ3 = 50(1.07/1.205)3 = 35.01 c. a1 = 35.52/40 = 0.8880 a2 = 47.31/60 = 0.7885 a3 = 35.01/50 = 0.7002 d. Using a constant risk-adjusted discount rate is equivalent to assuming that at decreases at a constant compounded rate. 103.

It is correct that,
25、for a high beta project, you should discount all cash flows at a high rate. Thus, the higher the risk of the cash outflows, the less you should worry about them because, the higher the discount rate, the closer the present value of these cash flows is to zero. This result does make sense. It is bett
26、er to have a series of payments that are high when the market is booming and low when it is slumping (i.e., a high beta) than the reverse. The beta of an investment is independent of the sign of the cash flows. If an investment has a high beta for anyone paying out the cash flows, it must have a hig
27、h beta for anyone receiving them. If the sign of the cash flows affected the discount rate, each asset would have one value for the buyer and one for the seller, which is clearly an impossible situation. 2. a. Since the risk of a dry hole is unlikely to be market-related, we can use the same discoun
28、t rate as for producing wells. Thus, using the Security Market Line: rnominal = 0.06 + (0.9 0.08) = 0.132 = 13.2% We know that: (1 + rnominal) = (1 + rreal) (1 + rinflation) Therefore: 8.85% 0.0885 1 1.041.132rreal b. c. Expected income from Well 1: (0.2 0) + (0.8 3 million) = $2.4 million Expected
29、income from Well 2: (0.2 0) + (0.8 2 million) = $1.6 million Discounting at 8.85 percent gives: (3.1914)(3million)million101.28853millionmillion10NPV101tt1$425,800NPV1(3.3888)(2million)10million1.28852millionmillion10NPV151tt2$3,222,300NPV2 74 d. For Well 1, one can certainly find a discount rate (a
30、nd hence a “fudge factor”) that, when applied to cash flows of $3 million per year for 10 years, will yield the correct NPV of $5,504,600. Similarly, for Well 2, one can find the appropriate discount rate. However, these two “fudge factors” will be different. Specifically, Well 2 will have a smaller
31、 “fudge factor” because its cash flows are more distant. With more distant cash flows, a smaller addition to the discount rate has a larger impact on present value. 3.
