罗斯公司理财第九版第十章课后答案对应版第十章：风险与收益：市场历史的启示1. 因为公司的表现具有不可预见性。
2. 投资者很容易看到最坏的投资结果，但是确很难预测到。
3. 不是，股票具有更高的风险，一些投资者属于风险规避者，他们认为这点额外的报酬率还不至于吸引他们付出更高风险的代价。
4. 股票市场与赌博是不同的，它实际是个零和市场，所有人都可能赢。
而且投机者带给市场更高的流动性，有利于市场效率。
5. 在80 年代初是最高的，因为伴随着高通胀和费雪效应。
6. 有可能，当投资风险资产报酬非常低，而无风险资产报酬非常高，或者同时出现这两种现象时就会发生这样的情况。
7. 相同，假设两公司2 年前股票价格都为P0，则两年后G 公司股票价格为1.1*0.9* P0，而S 公司股票价格为0.9*1.1 P0，所以两个公司两年后的股价是一样的。
8. 不相同，Lake Minerals 2年后股票价格= 100(1.10)(1.10) = $121.00 而SmallTown Furniture 2年后股票价格= 100(1.25)(.95) = $118.759. 算数平均收益率仅仅是对所有收益率简单加总平均，它没有考虑到所有收益率组合的效果，而几何平均收益率考虑到了收益率组合的效果，所以后者比较重要。
10. 不管是否考虑通货膨胀因素，其风险溢价没有变化，因为风险溢价是风险资产收益率与无风险资产收益率的差额，若这两者都考虑到通货膨胀的因素，其差额仍然是相互抵消的。
而在考虑税收后收益率就会降低，因为税后收益会降低。
11. R = [($104 – 92) + 1.45] / $92 = .1462 or 14.62%12. Dividend yield = $1.45 / $92 = .0158 or 1.58%Capital gains yield = ($104 – 92) / $92 = .1304 or 13.04%13. R = [($81 – 92) + 1.45] / $92 = –.1038 or –10.38%Dividend yield = $1.45 / $92 = .0158 or 1.58%Capital gains yield = ($81 – 92) / $92 = –.1196 or –11.96%14.15. a. To find the average return, we sum all the returns and divide by the number of returns, so: Arithmetic average return = (.34 +.16 + .19 – .21 + .08)/5 = .1120 or 11.20% b. Using the equation to calculate variance, we find:Variance = 1/4[(.34 – .112)⌒2 + (.16 – .112)⌒2 + (.19 – .112)⌒2 + (–.21 – .112)⌒2 +(.08 – .112)⌒2] = 0.041270So, the standard deviation is:Standard deviation = (0.041270)⌒1/2 = 0.2032 or 20.32%16. a. To calculate the average real return, we can use the average return of the asset and the average inflation rate in the Fisher equation. Doing so, we find:(1 + R) = (1 + r)(1 + h)则r = (1.1120/1.042) – 1=.0672 or 6.72%b. The average risk premium is simply the average return of the asset, minus the average real riskfree rate, so, the average risk premium for this asset would be:RP = R –f R= .1120 – .0510= .0610 or 6.10%17. We can find the average real risk-free rate using the Fisher equation. The average realrisk-free rate was: (1 + R) = (1 + r)(1 + h)r f = (1.051/1.042) – 1= .0086 or 0.86%And to calculate the average real risk premium, we can subtract the average risk-free rate from the average real return. So, the average real risk premium was:rp = r – r f = 6.72% – 0.86%= 5.85%18. Apply the five-year holding-period return formula to calculate the total return of the stock over the five-year period, we find:5-year holding-period return = [(1 + R1)(1 + R2)(1 +R3)(1 +R4)(1 +R5)] – 1= [(1 + .1843)(1 + .1682)(1 + .0683)(1 + .3219)(1 – .1987)] – 1= 0.5655 or 56.55%19. To find the return on the zero coupon bond, we first need to find the price of the bond today. Since one year has elapsed, the bond now has 29 years to maturity, so the price today is: P1 = $1,000/1.0929 = $82.15There are no intermediate cash flows on a zero coupon bond, so the return is the capital gains, or: R = ($82.15 – 77.81) / $77.81 = .0558 or 5.58%20. The return of any asset is the increase in price, plus any dividends or cash flows, all divided by the initial price. This stock paid no dividend, so the return was:R = ($82.01 – 75.15) / $75.15 = .0913 or 9.13%This is the return for three months, so the APR is:APR = 4(9.13%) = 36.51%And the EAR is:EAR = (1 + .0913)⌒4 – 1 = .4182 or 41.82%21.22. To calculate the arithmetic and geometric average returns, we must first calculate the return for each year. The return for each year is:R1 = ($55.83 – 49.62 + 0.68) / $49.62 = .1389 or 13.89%R2 = ($57.03 – 55.83 + 0.73) / $55.83 = .0346 or 3.46%R3 = ($50.25 – 57.03 + 0.84) / $57.03 = –.1042 or –10.42%R4 = ($53.82 – 50.25 + 0.91)/ $50.25 = .0892 or 8.92%R5 = ($64.18 – 53.82 + 1.02) / $53.82 = .2114 or 21.14%The arithmetic average return was:R A = (0.1389 + 0.0346 – 0.1042 + 0.0892 + 0.2114)/5 = 0.0740 or 7.40%And the geometric average return was:R G = [(1 + .1389)(1 + .0346)(1 – .1042)(1 + .0892)(1 + .2114)]1/5 – 1 = 0.0685 or 6.85% 23. To find the return on the coupon bond, we first need to find the price of the bond today. Since one year has elapsed, the bond now has six years to maturity, so the price today is:P1 = $70(PVIFA8%,6) + $1,000/1.086 = $953.77You received the coupon payments on the bond, so the nominal return was:R = ($953.77 – 943.82 + 70) / $943.82 = .0847 or 8.47%And using the Fisher equation to find the real return, we get:r = (1.0847 / 1.048) – 1 = .0350 or 3.50%24. Looking at the long-term government bond return history in Table 10.2, we see that the mean return was 6.1 percent, with a standard deviation of 9.4 percent. Inthe normal probability distribution, approximately 2/3 of the observations are within one standard deviation of the mean. This means that 1/3 of the observations are outside one standard deviation away from the mean. Or:Pr(R15.5)≈1/3But we are only interested in one tail here, that is, returns less than –3.3 percent, so: Pr(RYou can use the z-statistic and the cumulative normal distribution table to findthe answer as well. Doing so, we find:z = (–3.3% – 6.1)/9.4% = –1.00Looking at the z-table, this gives a probability of 15.87%, or:Pr(RThe range of returns you would expect to see 95 percent of the time is the mean plus or minus 2 standard deviations, or:The range of returns you would expect to see 99 percent of the time is the mean plus or minus 3 standard deviations, or:99% level: R ± 3 = 6.1% ± 3(9.4%) = –22.10% to 34.30%。

to abandon, and timing options.4. Decision trees represent an approach for valuing projects with these hidden, or real, options.Concept Questions1. Forecasting Risk What is forecasting risk? In general, would the degree of forecasting risk begreater for a new product or a cost-cutting proposal? Why?2. Sensitivity Analysis and Scenario Analysis What is the essential difference betweensensitivity analysis and scenario analysis?3. Marginal Cash Flows A coworker claims that looking at all this marginal this and incrementalthat is just a bunch of nonsense, and states, “Listen, if our average revenue doesn’t exceed our average cost, then we will have a negative cash flow, and we will go broke!” How do you respond?4. Break-Even Point As a shareholder of a firm that is contemplating a new project, would yoube more concerned with the accounting break-even point, the cash break-even point (the point at which operating cash flow is zero), or the financial break-even point? Why?5. Break-Even Point Assume a firm is considering a new project that requires an initialinvestment and has equal sales and costs over its life. Will the project reach the accounting, cash, or financial break-even point first? Which will it reach next? Last? Will this order always apply?6. Real Options Why does traditional NPV analysis tend to underestimate the true value of acapital budgeting project?7. Real Options The Mango Republic has just liberalized its markets and is now permittingforeign investors. Tesla Manufacturing has analyzed starting a project in the country and has determined that the project has a negative NPV. Why might the company go ahead with the project? What type of option is most likely to add value to this project?8. Sensitivity Analysis and Breakeven How does sensitivity analysis interact with break-evenanalysis?9. Option to Wait An option can often have more than one source of value. Consider a loggingcompany. The company can log the timber today or wait another year (or more) to log the timber.What advantages would waiting one year potentially have?10. Project Analysis You are discussing a project analysis with a coworker. The project involvesreal options, such as expanding the project if successful, or abandoning the project if it fails. Your coworker makes the following statement: “This analysis is ridiculous. We looked at expanding or abandoning the project in two years, but there are many other options we should consider. For example, we could expand in one year, and expand further in two years. Or we could expand in one year, and abandon the project in two years. There are too many options for us to examine.Because of this, anything this analysis would give us is worthless.” How would you evaluate this statement? Considering that with any capital budgeting project there are an infinite number of real options, when do you stop the option analysis on an individual project?Questions and Problems: connect™BASIC (Questions 1–10)1. Sensitivity Analysis and Break-Even Point We are evaluating a project that costs$724,000, has an eight-year life, and has no salvage value. Assume that depreciation is straight-line to zero over the life of the project. Sales are projected at 75,000 units per year. Price per unit is $39, variable cost per unit is $23, and fixed costs are $850,000 per year. The tax rate is 35 percent, and we require a 15 percent return on this project.1. Calculate the accounting break-even point.2. Calculate the base-case cash flow and NPV. What is the sensitivity of NPV to changes inthe sales figure? Explain what your answer tells you about a 500-unit decrease in projected sales.3. What is the sensitivity of OCF to changes in the variable cost figure? Explain what youranswer tells you about a $1 decrease in estimated variable costs.2. Scenario Analysis In the previous problem, suppose the projections given for price, quantity,variable costs, and fixed costs are all accurate to within ±10 percent. Calculate the best-case and worst-case NPV figures.3. Calculating Breakeven In each of the following cases, find the unknown variable. Ignoretaxes.4. Financial Breakeven L.J.’s Toys Inc. just purchased a $250,000 machine to produce toy cars.The machine will be fully depreciated by the straight-line method over its five-year economic life.Each toy sells for $25. The variable cost per toy is $6, and the firm incurs fixed costs of $360,000 each year. The corporate tax rate for the company is 34 percent. The appropriate discount rate is12 percent. What is the financial break-even point for the project?5. Option to Wait Your company is deciding whether to invest in a new machine. The newmachine will increase cash flow by $340,000 per year. You believe the technology used in the machine has a 10-year life; in other words, no matter when you purchase the machine, it will be obsolete 10 years from today. The machine is currently priced at $1,800,000. The cost of the machine will decline by $130,000 per year until it reaches $1,150,000, where it will remain. If your required return is 12 percent, should you purchase the machine? If so, when should you purchase it?6. Decision Trees Ang Electronics, Inc., has developed a new DVDR. If the DVDR is successful,the present value of the payoff (when the product is brought to market) is $22 million. If the DVDR fails, the present value of the payoff is $9 million. If the product goes directly to market, there is a50 percent chance of success. Alternatively, Ang can delay the launch by one year and spend $1.5million to test market the DVDR. Test marketing would allow the firm to improve the product and increase the probability of success to 80 percent. The appropriate discount rate is 11 percent.Should the firm conduct test marketing?7. Decision Trees The manager for a growing firm is considering the launch of a new product. Ifthe product goes directly to market, there is a 50 percent chance of success. For $135,000 the manager can conduct a focus group that will increase the product’s chance of success to 65 percent. Alternatively, the manager has the option to pay a consulting firm $400,000 to research the market and refine the product. The consulting firm successfully launches new products 85 percent of the time. If the firm successfully launches the product, the payoff will be $1.5 million. If the product is a failure, the NPV is zero. Which action will result in the highest expected payoff to the firm?8. Decision Trees B&B has a new baby powder ready to market. If the firm goes directly to themarket with the product, there is only a 55 percent chance of success. However, the firm can conduct customer segment research, which will take a year and cost $1.8 million. By going through research, B&B will be able to better target potential customers and will increase the probability of success to 70 percent. If successful, the baby powder will bring a present value profit (at time of initial selling) of $28 million. If unsuccessful, the present value payoff is only $4 million. Should the firm conduct customer segment research or go directly to market? The appropriate discount rate is15 percent.9. Financial Break-Even Analysis You are considering investing in a company that cultivatesabalone for sale to local restaurants. Use the following information:The discount rate for the company is 15 percent, the initial investment in equipment is $360,000, and the project’s economic life is seven years. Assume the equipment is depreciated on a straight-line basis over the project’s life.1. What is the accounting break-even level for the project?2. What is the financial break-even level for the project?10. Financial Breakeven Niko has purchased a brand new machine to produce its High Flight lineof shoes. The machine has an economic life of five years. The depreciation schedule for the machine is straight-line with no salvage value. The machine costs $390,000. The sales price per pair of shoes is $60, while the variable cost is $14. $185,000 of fixed costs per year are attributed to the machine. Assume that the corporate tax rate is 34 percent and the appropriate discount rate is 8 percent. What is the financial break-even point?INTERMEDIATE (Questions 11–25)11. Break-Even Intuition Consider a project with a required return of R percent that costs $I andwill last for N years. The project uses straight-line depreciation to zero over the N-year life; there are neither salvage value nor net working capital requirements.1. At the accounting break-even level of output, what is the IRR of this project? The paybackperiod? The NPV?2. At the cash break-even level of output, what is the IRR of this project? The paybackperiod? The NPV?3. At the financial break-even level of output, what is the IRR of this project? The paybackperiod? The NPV?12. Sensitivity Analysis Consider a four-year project with the following information: Initial fixedasset investment = $380,000; straight-line depreciation to zero over the four-year life; zero salvage value; price = $54; variable costs = $42; fixed costs = $185,000; quantity sold = 90,000 units; tax rate = 34 percent. How sensitive is OCF to changes in quantity sold?13. Project Analysis You are considering a new product launch. The project will cost $960,000,have a four-year life, and have no salvage value; depreciation is straight-line to zero. Sales are projected at 240 units per year; price per unit will be $25,000; variable cost per unit will be $19,500; and fixed costs will be $830,000 per year. The required return on the project is 15 percent, and the relevant tax rate is 35 percent.1. Based on your experience, you think the unit sales, variable cost, and fixed costprojections given here are probably accurate to within ±10 percent. What are the upper and lower bounds for these projections? What is the base-case NPV? What are the best-case and worst-case scenarios?2. Evaluate the sensitivity of your base-case NPV to changes in fixed costs.3. What is the accounting break-even level of output for this project?14. Project Analysis McGilla Golf has decided to sell a new line of golf clubs. The clubs will sell for$750 per set and have a variable cost of $390 per set. The company has spent $150,000 for a marketing study that determined the company will sell 55,000 sets per year for seven years. The marketing study also determined that the company will lose sales of 12,000 sets of its high-priced clubs. The high-priced clubs sell at $1,100 and have variable costs of $620. The company will also increase sales of its cheap clubs by 15,000 sets. The cheap clubs sell for $400 and have variable costs of $210 per set. The fixed costs each year will be $8,100,000. The company has also spent $1,000,000 on research and development for the new clubs. The plant and equipment required will cost $18,900,000 and will be depreciated on a straight-line basis. The new clubs will also require an increase in net working capital of $1,400,000 that will be returned at the end of the project. The tax rate is 40 percent, and the cost of capital is 14 percent. Calculate the payback period, the NPV, and the IRR.15. Scenario Analysis In the previous problem, you feel that the values are accurate to withinonly ±10 percent. What are the best-case and worst-case NPVs? (Hint: The price and variable costs for the two existing sets of clubs are known with certainty; only the sales gained or lost are uncertain.)16. Sensitivity Analysis McGilla Golf would like to know the sensitivity of NPV to changes in theprice of the new clubs and the quantity of new clubs sold. What is the sensitivity of the NPV to each of these variables?17. Abandonment Value We are examining a new project. We expect to sell 9,000 units per yearat $50 net cash flow apiece for the next 10 years. In other words, the annual operating cash flow is projected to be $50 × 9,000 = $450,000. The relevant discount rate is 16 percent, and the initial investment required is $1,900,000.1. What is the base-case NPV?2. After the first year, the project can be dismantled and sold for $1,300,000. If expectedsales are revised based on the first year’s performance, when would it make sense to abandon the investment? In other words, at what level of expected sales would it make sense to abandon the project?3. Explain how the $1,300,000 abandonment value can be viewed as the opportunity cost ofkeeping the project in one year.18. Abandonment In the previous problem, suppose you think it is likely that expected sales willbe revised upward to 11,000 units if the first year is a success and revised downward to 4,000 units if the first year is not a success.1. If success and failure are equally likely, what is the NPV of the project? Consider thepossibility of abandonment in answering.2. What is the value of the option to abandon?19. Abandonment and Expansion In the previous problem, suppose the scale of the project canbe doubled in one year in the sense that twice as many units can be produced and sold. Naturally, expansion would be desirable only if the project were a success. This implies that if the project is a success, projected sales after expansion will be 22,000. Again assuming that success and failure are equally likely, what is the NPV of the project? Note that abandonment is still an option if the project is a failure. What is the value of the option to expand?20. Break-Even Analysis Your buddy comes to you with a sure-fire way to make some quickmoney and help pay off your student loans. His idea is to sell T-shirts with the words “I get” on them. “You get it?” He says, “You see all those bumper stickers and T-shirts that say ‘got milk’ or ‘got surf.’ So this says, ‘I get.’ It’s funny! All we have to do is buy a used silk screen press for $3,200 and we are in business!” Assume there are no fixed costs, and you depreciate the $3,200 in the first period. Taxes are 30 percent.1. What is the accounting break-even point if each shirt costs $7 to make and you can sellthem for $10 apiece?Now assume one year has passed and you have sold 5,000 shirts! You find out that the Dairy Farmers of America have copyrighted the “got milk” slogan and are requiring you to pay $12,000 to continue operations. You expect this craze will last for another three years and that your discount rate is 12 percent.2. What is the financial break-even point for your enterprise now?21. Decision Trees Young screenwriter Carl Draper has just finished his first script. It has action,drama, and humor, and he thinks it will be a blockbuster. He takes the script to every motion picture studio in town and tries to sell it but to no avail. Finally, ACME studios offers to buy the script for either (a) $12,000 or (b) 1 percent of the movie’s profits. There are two decisions the studio will have to make. First is to decide if the script is good or bad, and second if the movie is good or bad. First, there is a 90 percent chance that the script is bad. If it is bad, the studio does nothing more and throws the script out. If the script is good, they will shoot the movie. After the movie is shot, the studio will review it, and there is a 70 percent chance that the movie is bad. If the movie is bad, the movie will not be promoted and will not turn a profit. If the movie is good, the studio will promote heavily; the average profit for this type of movie is $20 million. Carl rejects the $12,000 and says he wants the 1 percent of profits. Was this a good decision by Carl?22. Option to Wait Hickock Mining is evaluating when to open a gold mine. The mine has 60,000ounces of gold left that can be mined, and mining operations will produce 7,500 ounces per year.The required return on the gold mine is 12 percent, and it will cost $14 million to open the mine.When the mine is opened, the company will sign a contract that will guarantee the price of gold for the remaining life of the mine. If the mine is opened today, each ounce of gold will generate an aftertax cash flow of $450 per ounce. If the company waits one year, there is a 60 percent probability that the contract price will generate an aftertax cash flow of $500 per ounce and a 40 percent probability that the aftertax cash flow will be $410 per ounce. What is the value of the option to wait?23. Abandonment Decisions Allied Products, Inc., is considering a new product launch. The firmexpects to have an annual operating cash flow of $22 million for the next 10 years. Allied Products uses a discount rate of 19 percent for new product launches. The initial investment is $84 million.Assume that the project has no salvage value at the end of its economic life.1. What is the NPV of the new product?2. After the first year, the project can be dismantled and sold for $30 million. If theestimates of remaining cash flows are revised based on the first year’s experience, at what level of expected cash flows does it make sense to abandon the project?24. Expansion Decisions Applied Nanotech is thinking about introducing a new surface cleaningmachine. The marketing department has come up with the estimate that Applied Nanotech can sell15 units per year at $410,000 net cash flow per unit for the next five years. The engineeringdepartment has come up with the estimate that developing the machine will take a $17 million initial investment. The finance department has estimated that a 25 percent discount rate should beused.1. What is the base-case NPV?2. If unsuccessful, after the first year the project can be dismantled and will have an aftertaxsalvage value of $11 million. Also, after the first year, expected cash flows will be revised up to 20 units per year or to 0 units, with equal probability. What is the revised NPV?25. Scenario Analysis You are the financial analyst for a tennis racket manufacturer. Thecompany is considering using a graphitelike material in its tennis rackets. The company has estimated the information in the following table about the market for a racket with the new material. The company expects to sell the racket for six years. The equipment required for the project has no salvage value. The required return for projects of this type is 13 percent, and the company has a 40 percent tax rate. Should you recommend the project?CHALLENGE (Questions 26–30)26. Scenario Analysis Consider a project to supply Detroit with 55,000 tons of machine screwsannually for automobile production. You will need an initial $1,700,000 investment in threading equipment to get the project started; the project will last for five years. The accounting department estimates that annual fixed costs will be $520,000 and that variable costs should be $220 per ton;accounting will depreciate the initial fixed asset investment straight-line to zero over the five-year project life. It also estimates a salvage value of $300,000 after dismantling costs. The marketing department estimates that the automakers will let the contract at a selling price of $245 per ton.The engineering department estimates you will need an initial net working capital investment of $600,000. You require a 13 percent return and face a marginal tax rate of 38 percent on this project.1. What is the estimated OCF for this project? The NPV? Should you pursue this project?2. Suppose you believe that the accounting department’s initial cost and salvage valueprojections are accurate only to within ±15 percent; the marketing department’s price estimate is accurate only to within ±10 percent; and the engineering department’s net working capital estimate is accurate only to within ±5 percent. What is your worst-case scenario for this project? Your best-case scenario? Do you still want to pursue the project? 27. Sensitivity Analysis In Problem 26, suppose you’re confident about your own projections, butyou’re a little unsure about Detroit’s actual machine screw requirements. What is the sensitivity of the project OCF to changes in the quantity supplied? What about the sensitivity of NPV to changes in quantity supplied? Given the sensitivity number you calculated, is there some minimum level of output below which you wouldn’t want to operate? Why?28. Abandonment Decisions Consider the following project for Hand Clapper, Inc. The companyis considering a four-year project to manufacture clap-command garage door openers. This project requires an initial investment of $10 million that will be depreciated straight-line to zero over the project’s life. An initial investment in net working capital of $1.3 million is required to support spare parts inventory; this cost is fully recoverable whenever the project ends. The company believes it can generate $7.35 million in pretax revenues with $2.4 million in total pretax operating costs. The tax rate is 38 percent, and the discount rate is 16 percent. The market value of the equipment over the life of the project is as follows:Lumber is sold by the company for its “pond value.” Pond value is the amount a mill will pay for a log delivered to the mill location. The price paid for logs delivered to a mill is quoted in dollars per thousands of board feet (MBF), and the price depends on the grade of the logs. The forest Bunyan Lumber is evaluating was planted by the company 20 years ago and is made up entirely of Douglas fir trees. The table here shows the current price per MBF for the three grades of timber the company feels will come from the stand:Steve believes that the pond value of lumber will increase at the inflation rate. The company is planning to thin the forest today, and it expects to realize a positive cash flow of $1,000 per acre from thinning. The thinning is done to increase the growth rate of the remaining trees, and it is always done 20 years following a planting.The major decision the company faces is when to log the forest. When the company logs the forest, it will immediately replant saplings, which will allow for a future harvest. The longer the forest is allowed to grow, the larger the harvest becomes per acre. Additionally, an older forest has a higher grade of timber. Steve has compiled the following table with the expected harvest per acre in thousands of board feet, along with the breakdown of the timber grades:The company expects to lose 5 percent of the timber it cuts due to defects and breakage.The forest will be clear-cut when the company harvests the timber. This method of harvesting allows for faster growth of replanted trees. All of the harvesting, processing, replanting, and transportation are to be handled by subcontractors hired by Bunyan Lumber. The cost of the logging is expected to be $140 per MBF. A road system has to be constructed and is expected to cost $50 per MBF on average. Sales preparation and administrative costs, excluding office overhead costs, are expected to be $18 per MBF.As soon as the harvesting is complete, the company will reforest the land. Reforesting costs include the following:All costs are expected to increase at the inflation rate.Assume all cash flows occur at the year of harvest. For example, if the company begins harvesting the timber 20 years from today, the cash flow from the harvest will be received 20 years from today. When the company logs the land, it will immediately replant the land with new saplings. The harvest period chosen will be repeated for the foreseeable future. The company’s nominal required return is 10 percent, and the inflation rate is expected to be 3.7 percent per year. Bunyan Lumber has a 35 percent tax rate.Clear-cutting is a controversial method of forest management. To obtain the necessary permits, Bunyan Lumber has agreed to contribute to a conservation fund every time it harvests the lumber. If the company harvested the forest today, the required contribution would be $250,000. The company has agreed that the required contribution will grow by 3.2 percent per year. When should the company harvest the forest?。

Earlier in the chapter, we saw how bonds were rated based on their credit risk. What you will find if you start looking at bonds of different ratings is that lower-rated bonds have higher yields.We stated earlier in this chapter that a bond’s yield is calculated assuming that all the promised payments will be made. As a result, it is really a promised yield, and it may or may not be what you will earn. In particular, if the issuer defaults, your actual yield will be lower, probably much lower. This fact is particularly important when it comes to junk bonds. Thanks to a clever bit of marketing, such bonds are now commonly called high-yield bonds, which has a much nicer ring to it; but now you recognize that these are really high promised yield bonds.Next, recall that we discussed earlier how municipal bonds are free from most taxes and, as a result, have much lower yields than taxable bonds. Investors demand the extra yield on a taxable bond as compensation for the unfavorable tax treatment. This extra compensation is the taxability premium.Finally, bonds have varying degrees of liquidity. As we discussed earlier, there are an enormous number of bond issues, most of which do not trade on a regular basis. As a result, if you wanted to sell quickly, you would probably not get as good a price as you could otherwise. Investors prefer liquid assets to illiquid ones, so they demand a liquidity premium on top of all the other premiums we have discussed. As a result, all else being the same, less liquid bonds will have higher yields than more liquid bonds.ConclusionIf we combine everything we have discussed, we find that bond yields represent the combined effect of no fewer than six factors. The first is the real rate of interest. On top of the real rate are five premiums representing compensation for (1) expected future inflation, (2) interest rate risk, (3) default risk, (4) taxability, and (5) lack of liquidity. As a result, determining the appropriate yield on a bond requires careful analysis of each of these factors.Summary and ConclusionsThis chapter has explored bonds, bond yields, and interest rates. We saw that:1. Determining bond prices and yields is an application of basic discounted cash flow principles.2. Bond values move in the direction opposite that of interest rates, leading to potential gains orlosses for bond investors.3. Bonds are rated based on their default risk. Some bonds, such as Treasury bonds, have no riskof default, whereas so-called junk bonds have substantial default risk.4. Almost all bond trading is OTC, with little or no market transparency in many cases. As a result,bond price and volume information can be difficult to find for some types of bonds.5. Bond yields and interest rates reflect six different factors: the real interest rate and fivepremiums that investors demand as compensation for inflation, interest rate risk, default risk, taxability, and lack of liquidity.In closing, we note that bonds are a vital source of financing to governments and corporations of all types. Bond prices and yields are a rich subject, and our one chapter, necessarily, touches on only the most important concepts and ideas. There is a great deal more we could say, but, instead, we will move on to stocks in our next chapter.Concept Questions1. Treasury Bonds Is it true that a U.S. Treasury security is risk-free?2. Interest Rate Risk Which has greater interest rate risk, a 30-year Treasury bond or a 30-year21. Using Bond Quotes Suppose the following bond quote for IOU Corporation appears in thefinancial page of today’s newspaper. Assume the bond has a face value of $1,000 and the current date is April 15, 2010. What is the yield to maturity of the bond? What is the current yield?22. Finding the Maturity You’ve just found a 10 percent coupon bond on the market that sells forpar value. What is the maturity on this bond?CHALLENGE (Questions 23–30)23. Components of Bond Returns Bond P is a premium bond with a 9 percent coupon. Bond D isa 5 percent coupon bond currently selling at a discount. Both bonds make annual payments, havea YTM of 7 percent, and have five years to maturity. What is the current yield for Bond P? For BondD? If interest rates remain unchanged, what is the expected capital gains yield over the next year for Bond P? For Bond D? Explain your answers and the interrelationship among the various types of yields.24. Holding Period Yield The YTM on a bond is the interest rate you earn on your investment ifinterest rates don’t change. If you actually sell the bond before it matures, your realized return is known as the holding period yield (HPY).1. Suppose that today you buy a 9 percent annual coupon bond for $1,140. The bond has 10years to maturity. What rate of return do you expect to earn on your investment?2. Two years from now, the YTM on your bond has declined by 1 percent, and you decide tosell. What price will your bond sell for? What is the HPY on your investment? Compare this yield to the YTM when you first bought the bond. Why are they different?25. Valuing Bonds The Morgan Corporation has two different bonds currently outstanding. Bond Mhas a face value of $20,000 and matures in 20 years. The bond makes no payments for the first six years, then pays $800 every six months over the subsequent eight years, and finally pays $1,000 every six months over the last six years. Bond N also has a face value of $20,000 and a maturity of20 years; it makes no coupon payments over the life of the bond. If the required return on boththese bonds is 8 percent compounded semiannually, what is the current price of Bond M? Of Bond N?26. R eal Cash Flows When Marilyn Monroe died, ex-husband Joe DiMaggio vowed to place freshflowers on her grave every Sunday as long as he lived. The week after she died in 1962, a bunch of fresh flowers that the former baseball player thought appropriate for the star cost about $8.Based on actuarial tables, “Joltin’ Joe” could expect to live for 30 years after the actress died.Assume that the EAR is 10.7 percent. Also, assume that the price of the flowers will increase at 3.5 percent per year, when expressed as an EAR. Assuming that each year has exactly 52 weeks, what is the present value of this commitment? Joe began purchasing flowers the week after Marilyn died.27. Real Cash Flows You are planning to save for retirement over the next 30 years. To save forretirement, you will invest $800 a month in a stock account in real dollars and $400 a month in a bond account in real dollars. The effective annual return of the stock account is expected to be 12 percent, and the bond account will earn 7 percent. When you retire, you will combine your money into an account with an 8 percent effective return. The inflation rate over this period is expected to be 4 percent. How much can you withdraw each month from your account in real terms assuminga 25-year withdrawal period? What is the nominal dollar amount of your last withdrawal?28. Real Cash Flows Paul Adams owns a health club in downtown Los Angeles. He charges hiscustomers an annual fee of $500 and has an existing customer base of 500. Paul plans to raise the annual fee by 6 percent every year and expects the club membership to grow at a constant rate of3 percent for the next five years. The overall expenses of running the health club are $75,000 ayear and are expected to grow at the inflation rate of 2 percent annually. After five years, Paul2. How many of the coupon bonds must East Coast Yachts issue to raise the $40 million? Howmany of the zeroes must it issue?3. In 20 years, what will be the principal repayment due if East Coast Yachts issues the couponbonds? What if it issues the zeroes?4. What are the company’s considerations in issuing a coupon bond compared to a zero couponbond?5. Suppose East Coast Yachts issues the coupon bonds with a make-whole call provision. Themake-whole call rate is the Treasury rate plus .40 percent. If East Coast calls the bonds in 7 years when the Treasury rate is 5.6 percent, what is the call price of the bond? What if it is 9.1 percent?6. Are investors really made whole with a make-whole call provision?7. After considering all the relevant factors, would you recommend a zero coupon issue or aregular coupon issue? Why? Would you recommend an ordinary call feature or a make-whole call feature? Why?。

股东选举公司的董事会,董事会任命该公司的管理层。
企业的所有权和控制权分离的组织形式是导致的代理关系存在的主要原因。
管理者可能追求自身或别人的利益最大化,而不是股东的利益最大化。
在这种环境下,他们可能因为目标不一致而存在代理问题。
2.非营利公司经常追求社会或政治任务等各种目标。
非营利公司财务管理的目标是获取并有效使用资金以最大限度地实现组织的社会使命。
3.这句话是不正确的。
管理者实施财务管理的目标就是最大化现有股票的每股价值，当前的股票价值反映了短期和长期的风险、时间以及未来现金流量。
4.有两种结论。
一种极端,在市场经济中所有的东西都被定价。
因此所有目标都有一个最优水平，包括避免不道德或非法的行为，股票价值最大化。
另一种极端,我们可以认为这是非经济现象,最好的处理方式是通过政治手段。
一个经典的思考问题给出了这种争论的答案:公司估计提高某种产品安全性的成本是30美元万。
然而,该公司认为提高产品的安全性只会节省20美元万。
请问公司应该怎么做呢”5.财务管理的目标都是相同的,但实现目标的最好方式可能是不同的,因为不同的国家有不同的社会、政治环境和经济制度。
6.管理层的目标是最大化股东现有股票的每股价值。
如果管理层认为能提高公司利润，使股价超过35美元,那么他们应该展开对恶意收购的斗争。
如果管理层认为该投标人或其它未知的投标人将支付超过每股35美元的价格收购公司,那么他们也应该展开斗争。
然而,如果管理层不能增加企业的价值,并且没有其他更高的投标价格,那么管理层不是在为股东的最大化权益行事。
现在的管理层经常在公司面临这些恶意收购的情况时迷失自己的方向。
7.其他国家的代理问题并不严重,主要取决于其他国家的私人投资者占比重较小。

这样的金额算多吗?如果承认超级运动员比如老虎·伍兹，演艺界的知名人士比如汤姆·汉克斯和奥普拉·温弗瑞，还有其他在他们各自领域非常出色的人赚的都不比这少或许有助于回答这个问题。
罗斯《公司理财》第9版英文原书课后部分章节答案
罗斯《公司理财》第9版精要版英文原书课后部分章节答案详细»1 / 17 CH5 11，13，18，19，20 11. To find the PV of a lump sum, we use: PV = FV / (1 + r) t PV = $1,000,000 / (1.10) 80 = $488.19 13. To answer this question, we can use either the FV or the PV formula. Both will give the same answer since they are the inverse of each other. We will use the FV formula, that is: FV = PV(1 + r) t Solving for r, we get: r = (FV / PV) 1 / t –1 r = ($1,260,000 / $150) 1/112 – 1 = .0840 or 8.40% To find the FV of the first prize, we use: FV = PV(1 + r) t FV = $1,260,000(1.0840) 33 = $18,056,409.94 18. To find the FV of a lump sum, we use: FV = PV(1 + r) t FV = $4,000(1.11) 45 = $438,120.97 FV = $4,000(1.11) 35 = $154,299.40 Better start early! 19. We need to find the FV of a lump sum. However, the money will only be invested for six years, so the number of periods is six. FV = PV(1 + r) t FV = $20,000(1.084)6 = $32,449.33 20. To answer this question, we can use either the FV or the PV formula. Both will give the same answer since they are the inverse of each other. We will use the FV formula, that is: FV = PV(1 + r) t Solving for t, we get: t = ln(FV / PV) / ln(1 + r) t = ln($75,000 / $10,000) / ln(1.11) = 19.31 So, the money must be invested for 19.31 years. However, you will not receive the money for another two years. From now, you’ll wait: 2 years + 19.31 years = 21.31 years CH6 16，24，27，42，58 16. For this problem, we simply need to find the FV of a lump sum using the equation: FV = PV(1 + r) t 2 / 17 It is important to note that compounding occurs semiannually. To account for this, we will divide the interest rate by two (the number of compounding periods in a year), and multiply the number of periods by two. Doing so, we get: FV = $2,100[1 + (.084/2)] 34 = $8,505.93 24. This problem requires us to find the FV A. The equation to find the FV A is: FV A = C{[(1 + r) t – 1] / r} FV A = $300[{[1 + (.10/12) ] 360 – 1} / (.10/12)] = $678,146.38 27. The cash flows are annual and the compounding period is quarterly, so we need to calculate the EAR to make the interest rate comparable with the timing of the cash flows. Using the equation for the EAR, we get: EAR = [1 + (APR / m)] m – 1 EAR = [1 + (.11/4)] 4 – 1 = .1146 or 11.46% And now we use the EAR to find the PV of each cash flow as a lump sum and add them together: PV = $725 / 1.1146 + $980 / 1.1146 2 + $1,360 / 1.1146 4 = $2,320.36 42. The amount of principal paid on the loan is the PV of the monthly payments you make. So, the present value of the $1,150 monthly payments is: PV A = $1,150[(1 – {1 / [1 + (.0635/12)]} 360 ) / (.0635/12)] = $184,817.42 The monthly payments of $1,150 will amount to a principal payment of $184,817.42. The amount of principal you will still owe is: $240,000 – 184,817.42 = $55,182.58 This remaining principal amount will increase at the interest rate on the loan until the end of the loan period. So the balloon payment in 30 years, which is the FV of the remaining principal will be: Balloon payment = $55,182.58[1 + (.0635/12)] 360 = $368,936.54 58. To answer this question, we should find the PV of both options, and compare them. Since we are purchasing the car, the lowest PV is the best option. The PV of the leasing is simply the PV of the lease payments, plus the $99. The interest rate we would use for the leasing option is the same as the interest rate of the loan. The PV of leasing is: PV = $99 + $450{1 –[1 / (1 + .07/12) 12(3) ]} / (.07/12) = $14,672.91 The PV of purchasing the car is the current price of the car minus the PV of the resale price. The PV of the resale price is: PV = $23,000 / [1 + (.07/12)] 12(3) = $18,654.82 The PV of the decision to purchase is: $32,000 – 18,654.82 = $13,345.18 3 / 17 In this case, it is cheaper to buy the car than leasing it since the PV of the purchase cash flows is lower. To find the breakeven resale price, we need to find the resale price that makes the PV of the two options the same. In other words, the PV of the decision to buy should be: $32,000 – PV of resale price = $14,672.91 PV of resale price = $17,327.09 The resale price that would make the PV of the lease versus buy decision is the FV ofthis value, so: Breakeven resale price = $17,327.09[1 + (.07/12)] 12(3) = $21,363.01 CH7 3，18，21，22，31 3. The price of any bond is the PV of the interest payment, plus the PV of the par value. Notice this problem assumes an annual coupon. The price of the bond will be: P = $75({1 – [1/(1 + .0875)] 10 } / .0875) + $1,000[1 / (1 + .0875) 10 ] = $918.89 We would like to introduce shorthand notation here. Rather than write (or type, as the case may be) the entire equation for the PV of a lump sum, or the PV A equation, it is common to abbreviate the equations as: PVIF R,t = 1 / (1 + r) t which stands for Present V alue Interest Factor PVIFA R,t = ({1 – [1/(1 + r)] t } / r ) which stands for Present V alue Interest Factor of an Annuity These abbreviations are short hand notation for the equations in which the interest rate and the number of periods are substituted into the equation and solved. We will use this shorthand notation in remainder of the solutions key. 18. The bond price equation for this bond is: P 0 = $1,068 = $46(PVIFA R%,18 ) + $1,000(PVIF R%,18 ) Using a spreadsheet, financial calculator, or trial and error we find: R = 4.06% This is thesemiannual interest rate, so the YTM is: YTM = 2 4.06% = 8.12% The current yield is:Current yield = Annual coupon payment / Price = $92 / $1,068 = .0861 or 8.61% The effective annual yield is the same as the EAR, so using the EAR equation from the previous chapter: Effective annual yield = (1 + 0.0406) 2 – 1 = .0829 or 8.29% 20. Accrued interest is the coupon payment for the period times the fraction of the period that has passed since the last coupon payment. Since we have a semiannual coupon bond, the coupon payment per six months is one-half of the annual coupon payment. There are four months until the next coupon payment, so two months have passed since the last coupon payment. The accrued interest for the bond is: Accrued interest = $74/2 × 2/6 = $12.33 And we calculate the clean price as: 4 / 17 Clean price = Dirty price –Accrued interest = $968 –12.33 = $955.67 21. Accrued interest is the coupon payment for the period times the fraction of the period that has passed since the last coupon payment. Since we have a semiannual coupon bond, the coupon payment per six months is one-half of the annual coupon payment. There are two months until the next coupon payment, so four months have passed since the last coupon payment. The accrued interest for the bond is: Accrued interest = $68/2 × 4/6 = $22.67 And we calculate the dirty price as: Dirty price = Clean price + Accrued interest = $1,073 + 22.67 = $1,095.67 22. To find the number of years to maturity for the bond, we need to find the price of the bond. Since we already have the coupon rate, we can use the bond price equation, and solve for the number of years to maturity. We are given the current yield of the bond, so we can calculate the price as: Current yield = .0755 = $80/P 0 P 0 = $80/.0755 = $1,059.60 Now that we have the price of the bond, the bond price equation is: P = $1,059.60 = $80[(1 – (1/1.072) t ) / .072 ] + $1,000/1.072 t We can solve this equation for t as follows: $1,059.60(1.072) t = $1,111.11(1.072) t –1,111.11 + 1,000 111.11 = 51.51(1.072) t2.1570 = 1.072 t t = log 2.1570 / log 1.072 = 11.06 11 years The bond has 11 years to maturity.31. The price of any bond (or financial instrument) is the PV of the future cash flows. Even though Bond M makes different coupons payments, to find the price of the bond, we just find the PV of the cash flows. The PV of the cash flows for Bond M is: P M = $1,100(PVIFA 3.5%,16 )(PVIF 3.5%,12 ) + $1,400(PVIFA3.5%,12 )(PVIF 3.5%,28 ) + $20,000(PVIF 3.5%,40 ) P M = $19,018.78 Notice that for the coupon payments of $1,400, we found the PV A for the coupon payments, and then discounted the lump sum back to today. Bond N is a zero coupon bond with a $20,000 par value, therefore, the price of the bond is the PV of the par, or: P N = $20,000(PVIF3.5%,40 ) = $5,051.45 CH8 4，18，20，22，244. Using the constant growth model, we find the price of the stock today is: P 0 = D 1 / (R – g) = $3.04 / (.11 – .038) = $42.22 5 / 17 18. The price of a share of preferred stock is the dividend payment divided by the required return. We know the dividend payment in Year 20, so we can find the price of the stock in Y ear 19, one year before the first dividend payment. Doing so, we get: P 19 = $20.00 / .064 P 19 = $312.50 The price of the stock today is the PV of the stock price in the future, so the price today will be: P 0 = $312.50 / (1.064) 19 P 0 = $96.15 20. We can use the two-stage dividend growth model for this problem, which is: P 0 = [D 0 (1 + g 1 )/(R – g 1 )]{1 – [(1 + g 1 )/(1 + R)] T }+ [(1 + g 1 )/(1 + R)] T [D 0 (1 + g 2 )/(R –g 2 )] P0 = [$1.25(1.28)/(.13 –.28)][1 –(1.28/1.13) 8 ] + [(1.28)/(1.13)] 8 [$1.25(1.06)/(.13 – .06)] P 0 = $69.55 22. We are asked to find the dividend yield and capital gains yield for each of the stocks. All of the stocks have a 15 percent required return, which is the sum of the dividend yield and the capital gains yield. To find the components of the total return, we need to find the stock price for each stock. Using this stock price and the dividend, we can calculate the dividend yield. The capital gains yield for the stock will be the total return (required return) minus the dividend yield. W: P 0 = D 0 (1 + g) / (R – g) = $4.50(1.10)/(.19 – .10) = $55.00 Dividend yield = D 1 /P 0 = $4.50(1.10)/$55.00 = .09 or 9% Capital gains yield = .19 – .09 = .10 or 10% X: P 0 = D 0 (1 + g) / (R – g) = $4.50/(.19 – 0) = $23.68 Dividend yield = D 1 /P 0 = $4.50/$23.68 = .19 or 19% Capital gains yield = .19 – .19 = 0% Y: P 0 = D 0 (1 + g) / (R – g) = $4.50(1 – .05)/(.19 + .05) = $17.81 Dividend yield = D 1 /P 0 = $4.50(0.95)/$17.81 = .24 or 24% Capital gains yield = .19 – .24 = –.05 or –5% Z: P 2 = D 2 (1 + g) / (R – g) = D 0 (1 + g 1 ) 2 (1 +g 2 )/(R – g 2 ) = $4.50(1.20) 2 (1.12)/(.19 – .12) = $103.68 P 0 = $4.50 (1.20) / (1.19) + $4.50(1.20) 2 / (1.19) 2 + $103.68 / (1.19) 2 = $82.33 Dividend yield = D 1 /P 0 = $4.50(1.20)/$82.33 = .066 or 6.6% Capital gains yield = .19 – .066 = .124 or 12.4% In all cases, the required return is 19%, but the return is distributed differently between current income and capital gains. High growth stocks have an appreciable capital gains component but a relatively small current income yield; conversely, mature, negative-growth stocks provide a high current income but also price depreciation over time. 24. Here we have a stock with supernormal growth, but the dividend growth changes every year for the first four years. We can find the price of the stock in Y ear 3 since the dividend growth rate is constant after the third dividend. The price of the stock in Y ear 3 will be the dividend in Y ear 4, divided by the required return minus the constant dividend growth rate. So, the price in Y ear 3 will be: 6 / 17 P3 = $2.45(1.20)(1.15)(1.10)(1.05) / (.11 – .05) = $65.08 The price of the stock today will be the PV of the first three dividends, plus the PV of the stock price in Y ear 3, so: P 0 = $2.45(1.20)/(1.11) + $2.45(1.20)(1.15)/1.11 2 + $2.45(1.20)(1.15)(1.10)/1.11 3 + $65.08/1.11 3 P 0 = $55.70 CH9 3，4，6，9，15 3. Project A has cash flows of $19,000 in Y ear 1, so the cash flows are short by $21,000 of recapturing the initial investment, so the payback for Project A is: Payback = 1 + ($21,000 / $25,000) = 1.84 years Project B has cash flows of: Cash flows = $14,000 + 17,000 + 24,000 = $55,000 during this first three years. The cash flows are still short by $5,000 of recapturing the initial investment, so the payback for Project B is: B: Payback = 3 + ($5,000 / $270,000) = 3.019 years Using the payback criterion and a cutoff of 3 years, accept project A and reject project B. 4. When we use discounted payback, we need to find the value of all cash flows today. The value today of the project cash flows for the first four years is: V alue today of Y ear 1 cash flow = $4,200/1.14 = $3,684.21 V alue today of Y ear 2 cash flow = $5,300/1.14 2 = $4,078.18 V alue today of Y ear 3 cash flow = $6,100/1.14 3 = $4,117.33 V alue today of Y ear 4 cash flow = $7,400/1.14 4 = $4,381.39 To findthe discounted payback, we use these values to find the payback period. The discounted first year cash flow is $3,684.21, so the discounted payback for a $7,000 initial cost is: Discounted payback = 1 + ($7,000 – 3,684.21)/$4,078.18 = 1.81 years For an initial cost of $10,000, the discounted payback is: Discounted payback = 2 + ($10,000 –3,684.21 –4,078.18)/$4,117.33 = 2.54 years Notice the calculation of discounted payback. We know the payback period is between two and three years, so we subtract the discounted values of the Y ear 1 and Y ear 2 cash flows from the initial cost. This is the numerator, which is the discounted amount we still need to make to recover our initial investment. We divide this amount by the discounted amount we will earn in Y ear 3 to get the fractional portion of the discounted payback. If the initial cost is $13,000, the discounted payback is: Discounted payback = 3 + ($13,000 – 3,684.21 – 4,078.18 – 4,117.33) / $4,381.39 = 3.26 years 7 / 17 6. Our definition of AAR is the average net income divided by the average book value. The average net income for this project is: A verage net income = ($1,938,200 + 2,201,600 + 1,876,000 + 1,329,500) / 4 = $1,836,325 And the average book value is: A verage book value = ($15,000,000 + 0) / 2 = $7,500,000 So, the AAR for this project is: AAR = A verage net income / A verage book value = $1,836,325 / $7,500,000 = .2448 or 24.48% 9. The NPV of a project is the PV of the outflows minus the PV of the inflows. Since the cash inflows are an annuity, the equation for the NPV of this project at an 8 percent required return is: NPV = –$138,000 + $28,500(PVIFA 8%, 9 ) = $40,036.31 At an 8 percent required return, the NPV is positive, so we would accept the project. The equation for the NPV of the project at a 20 percent required return is: NPV = –$138,000 + $28,500(PVIFA 20%, 9 ) = –$23,117.45 At a 20 percent required return, the NPV is negative, so we would reject the project. We would be indifferent to the project if the required return was equal to the IRR of the project, since at that required return the NPV is zero. The IRR of the project is: 0 = –$138,000 + $28,500(PVIFA IRR, 9 ) IRR = 14.59% 15. The profitability index is defined as the PV of the cash inflows divided by the PV of the cash outflows. The equation for the profitability index at a required return of 10 percent is: PI = [$7,300/1.1 + $6,900/1.1 2 + $5,700/1.1 3 ] / $14,000 = 1.187 The equation for the profitability index at a required return of 15 percent is: PI = [$7,300/1.15 + $6,900/1.15 2 + $5,700/1.15 3 ] / $14,000 = 1.094 The equation for the profitability index at a required return of 22 percent is: PI = [$7,300/1.22 + $6,900/1.22 2 + $5,700/1.22 3 ] / $14,000 = 0.983 8 / 17 We would accept the project if the required return were 10 percent or 15 percent since the PI is greater than one. We would reject the project if the required return were 22 percent since the PI。

罗斯《公司理财》第9版笔记和课后习题（含考研真题）详解[视频详解]（股票估值）【圣才出品】罗斯《公司理财》第9版笔记和课后习题（含考研真题）详解[视频详解]第9章股票估值9.1复习笔记1．不同类型股票的估值（1）零增长股利股利不变时，一股股票的价格由下式给出：在这里假定Div1=Div2=…=Div。
（2）固定增长率股利如果股利以恒定的速率增长，那么一股股票的价格就为：式中，g是增长率；Div是第一期期末的股利。
（3）变动增长率股利2．股利折现模型中的参数估计（1）对增长率g的估计有效估计增长率的方法是：g=留存收益比率×留存收益收益率（ROE）只要公司保持其股利支付率不变，g就可以表示公司的股利增长率以及盈利增长率。
（2）对折现率R的估计对于折现率R的估计为：R=Div/P0+g该式表明总收益率R由两部分组成。
其中，第一部分被称为股利收益率，是预期的现金股利与当前的价格之比。
3．增长机会每股股价可以写做：该式表明，每股股价可以看做两部分的加和。
第一部分（EPS/R）是当公司满足于现状，而将其盈利全部发放给投资者时的价值；第二部分是当公司将盈利留存并用于投资新项目时的新增价值。
当公司投资于正NPVGO的增长机会时，公司价值增加。
反之，当公司选择负NPVGO 的投资机会时，公司价值降低。
但是，不管项目的NPV是正的还是负的，盈利和股利都是增长的。
不应该折现利润来获得每股价格，因为有部分盈利被用于再投资了。
只有股利被分到股东手中，也只有股利可以加以折现以获得股票价格。
4．市盈率即股票的市盈率是三个因素的函数：（1）增长机会。
拥有强劲增长机会的公司具有高市盈率。
（2）风险。
低风险股票具有高市盈率。
（3）会计方法。
采用保守会计方法的公司具有高市盈率。
5．股票市场交易商：持有一项存货，然后准备在任何时点进行买卖。
经纪人：将买者和卖者撮合在一起，但并不持有存货。
9.2课后习题详解一、概念题1．股利支付率（payout ratio）答：股利支付率一般指公司发放给普通股股东的现金股利占总利润的比例。
Cha10 罗斯公司理财第九版原版书课后习题
Company Stock One option in the 401(k) plan is stock in East Coast Yachts. The company is currently privately held. However, when you interviewed with the owner, Larissa Warren, she informed you the company was expected to go public in the next three to four years. Until then, a company stock price is simply set each year by the board of directors.Bledsoe S&P 500 Index Fund This mutual fund tracks the S&P 500. Stocks in the fund are weighted exactly the same as the S&P 500. This means the fund return is approximately the return on the S&P 500, minus expenses. Because an index fund purchases assets based on the composition of the index it is following, the fund manager is not required to research stocks and make investment decisions. The result is that the fund expenses are usually low. The Bledsoe S&P 500 Index Fund charges expenses of .15 percent of assets per year.Bledsoe Small-Cap Fund This fund primarily invests in small-capitalization stocks. As such, the returns of the fund are more volatile. The fund can also invest 10 percent of its assets in companies based outside the United States. This fund charges 1.70 percent in expenses.Bledsoe Large-Company Stock Fund This fund invests primarily in large-capitalization stocks of companies based in the United States. The fund is managed by Evan Bledsoe and has outperformed the market in six of the last eight years. The fund charges 1.50 percent in expenses.Bledsoe Bond Fund This fund invests in long-term corporate bonds issued by U.S.–domiciled companies. The fund is restricted to investments in bonds with an investment-grade credit rating. This fund charges 1.40 percent in expenses.Bledsoe Money Market Fund This fund invests in short-term, high–credit quality debt instruments, which include Treasury bills. As such, the return on the money market fund is only slightly higher than the return on Treasury bills. Because of the credit quality and short-term nature of the investments, there is only a very slight risk of negative return. The fund charges .60 percent in expenses.1. What advantages do the mutual funds offer compared to the company stock?2. Assume that you invest 5 percent of your salary and receive the full 5 percent match from EastCoast Yachts. What EAR do you earn from the match? What conclusions do you draw about matching plans?3. Assume you decide you should invest at least part of your money in large-capitalization stocksof companies based in the United States. What are the advantages and disadvantages of choosing the Bledsoe Large-Company Stock Fund compared to the Bledsoe S&P 500 Index Fund?4. The returns on the Bledsoe Small-Cap Fund are the most volatile of all the mutual funds offeredin the 401(k) plan. Why would you ever want to invest in this fund? When you examine the expenses of the mutual funds, you will notice that this fund also has the highest expenses. Does this affect your decision to invest in this fund?5. A measure of risk-adjusted performance that is often used is the Sharpe ratio. The Sharpe ratiois calculated as the risk premium of an asset divided by its standard deviation. The standard deviations and returns of the funds over the past 10 years are listed here. Calculate the Sharpe ratio for each of these funds. Assume that the expected return and standard deviation of the company stock will be 16 percent and 70 percent, respectively. Calculate the Sharpe ratio for the company stock. How appropriate is the Sharpe ratio for these assets? When would you use the Sharpe ratio?6. What portfolio allocation would you choose? Why? Explain your thinking carefully.。

如果税率为35%，贴现率为10%，请计算两者的EAC。
你会选哪一个？为什么？18. 计算竞标价格Alson企业需要别人在未来5年中，每年供应185 000箱螺丝钉，以满足接下来5年中生产上的需要，你决定参加竞标。
启动生产所需生产设备的成本为940 000美元，你采用直线法在其寿命内折旧完毕。
你估计这项设备5年后的残值为70 000美元。
每年的固定成本为305 000美元，变动成本为每箱9.25美元。
开始时你还需要75 000美元的净营运资本性投资。
如果税率为35%，必要贴现率为12%，你应该提交的报价是多少？19. 成本削减建议Geary机器商店为了提高生产效率，正在考虑一个4年期的项目。
购买一台560 000美元的新机器，估计每年税前可以节约成本210 000美元。
该机器适用MACRS的5年折旧率，项目结束时，机器的残值为80 000美元。
此外，刚开始时，它必须在零件存货上投资20 000美元；此后，每年需要追加3 000美元。
如果该商店的税率为35%，贴现率为9%，公司是否应该购买这台机器？20. 比较互斥项目Dangerfield工业系统公司（DISC）要在两个传送系统中做出选择。
A系统的成本为430 000美元，寿命为4年，每年需要110 000美元的税前运转成本；B系统的成本为570 000美元，寿命为6年，每年需要98 000美元的税前运转成本。
两个系统都采用直线法在它们的寿命内折旧完毕，残值都是0。
不管选择哪一个项目，磨损后都不再重置。
税率为34%，贴现率为11%，公司应该选择哪一个系统？21. 比较互斥项目在第20题中，如果DISC一直需要传送系统，因此当一个磨损后，就必须重置一个。
这时，公司应该选择哪一个系统？22. 计算投标价格 某项目在今后5年每年将向美国邮政总局供应1亿枚邮票。
假设你有一片闲置土地，5年前的价格是240万美元。
如果现在出售这片土地，那么税后可得270万美元。
如果5年后再出售，那么税后可得320万美元。
为了生产邮票，你需要进行410万美元的厂房和设备投资。
这些厂房和设备将按项目的5年寿命期、采用直线折旧法折旧为零。
项目结束时，设备可按54万美元的价格出售。
此外，该项目开始时需要60万美元的净营运资本，之后每年需要增加投资5万美元。
该项目的生产成本为每枚邮票0.5美分，每年的固定成本为95万美元。
如果所得税税率为34%，你的要求回报率为12%，那么你对该合同的投标价格为多少？23. 解释竞标价格在第22题中，假定你的制造设备实际使用3年类的MACRS折旧，而且你认为营运资本可以维持在每年25 000美元的水平。
这些新资料对你计算的竞标价格有什么影响？24. 比较互斥项目Vandalay实业公司正在考虑购买一台新机器来生产乳胶。
机器A需要花费2 900 000美元，可以使用6年。
变动成本为销售收入的35%，每年的固定成本为170 000美元。
机器B需要花费5 100 000美元，可以使用9年。
这台机器的变动成本为30%，每年的固定成本为130 000美元。
使用两台机器的年销售收入均为1 000万美元。
必要报酬率为10%，税率为35%。
两台机器都采用直线法折旧。
如果公司计划永久替代现有的已经磨损的机器，你应该选择哪台机器？25. 约当年均成本 近年来，节能灯越来越受欢迎，但从财务视角而言是否具有意义呢？假设普通60瓦白炽灯泡的成本为0.5美元，使用寿命为1 000小时；15瓦节能灯可产生相同效果的灯光，成本为3.5美元，使用寿命为12 000小时。
每千瓦时（度）电的费用为0.101美元，差不多就是全国平均水平。
每千瓦时指每1小时1 000瓦。
如果你的要求回报率为10%，每年的使用时间为500小时，那么每种灯泡的约当年均成本为多少？26. 保本点成本 由上题可知，用节能灯而不用白炽灯是不明智的。
不过，电的成本实际上往往随地点和用户不同而附录B各章习题及部分习题答案83不同(可从当地电力公司获得电价信息)。
对于每度电，西弗吉尼亚的工业用户可能只要支付0.04美元，而夏威夷的居民用户也许需要支付0.25美元。
那么上题中每度电的保本点成本是多少？27. 保本点重置 由上面两题可知，除非当地电价相当便宜，否则单纯从财务视角考虑，使用节能灯应是一个好选择。
不过，这里会产生另一个问题。
假设某个居住区居民大多使用白炽灯，平均每年使用500小时。
因为白炽灯泡平均已使用其寿命时间的一半，所以只剩下500小时。
此外，你无法辨认出灯泡的新旧。
那么，当电价为多少时，重置这些白炽灯泡才有意义？28. 资本预算问题 关于节能灯与白炽灯的使用问题（见25～27题），人们争论不休，褒贬不一。
以下内容没有特别顺序之分。
a. 白炽灯产生的热量比节能灯多。
b. 相对于白炽灯的价格，节能灯的价格可能会下降。
c. 节能灯不可避免含有一定量的水银，会产生环境污染，所以在处置烧坏的节能灯（以及打碎的节能灯）时，必须采取专门措施。
目前，尚没有一致认可的回收节能灯的方法。
白炽灯则不存在处置问题。
d. 根据灯所在地或灯的数量，替换灯泡的成本（即劳动力成本）存在很大差异。
e. 虽然水银排放很快会大幅下降，但燃煤发电仍占水银排放的相当大一部分。
排放的相当大一部分。
f. 发电厂仍占美国CO2g. 节能灯生产是能源和材料密集型的。
生产现场的水银污染和工人安全问题都需要关注。
h. 如果给建筑物的永久性设施装上节能灯，那么有可能出现灯未坏而人已走的情况。
i. 另一种照明技术是建立在发光二极管基础上的，现在正在加以改进。
