Project Analysis You are discussing a project analysis witha 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 w ithin ±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 newline 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 otherwords, 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 funn y! 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 pe rcent 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 movieis 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 newmaterial. 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’sinitial 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 p ercent. 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 evaluatingwas 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, andtransportation 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?。

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.

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?。

第5章净现值和投资评价的其他方法一、单选题河海公司目前有7个投资项目可供选择，每一项目的投资额与现值指数如下表：河海公司目前可用于投资的总金额为1200万，根据资本限量决策的方法，选出河海公司的最优投资方案组合（假设投资于证券市场的净现值为0）为（）。

（中央财大2011金融硕士）A．A+B+CB．C+D，剩下的钱投资于证券市场C．D+E，剩下的钱投资于证券市场D．D+F【答案】D【解析】所谓现值指数法又称盈利指数法，是指未来收益的现值总额和初始投资现值总额之比，其实质是每一元初始投资所能获取的未来收益的现值额，盈利指数可以表示为PI 初始投资所带来的后续现金流量的现值盈利指数（）初始投资当资金不足以支付所有净现值为正的项目时，在这种情况下就需要进行资本配置。

在资本配置时就应该优先考虑盈利指数大的项目。

D项，现值指数为：600÷1200×1.31+600÷1200×1.20=1.255，为最大。

二、概念题1．净现值（武汉理工大学2004研；首都经贸大学2005研）答：净现值指投资项目在投资期内各年的现金流量按一定的贴现率折算为现值后与初始投资额的差。

所用的贴现率可以是企业的资金成本，也可以是企业所要求的最低收益率水平。

净现值的计算公式为：。

利用净现值进行决策所依据的原理是，假设预计的现金流入在年末肯定可以实现，并把原始投资看成是按预定贴现率借入的。

当净现值为正数时偿还本息后该项目仍有剩余的收益，当净现值为零时偿还本息后一无所获，当净现值为负数时该项目收益不足以偿还本息。

净现值指标的决策标准是：如果投资项目的净现值大于零，接受该项目；如果投资项目的净现值小于零，放弃该项目；如果有多个互斥的投资项目相互竞争，选取净现值最大的投资项目。

净现值指标考虑了投资项目资金流量的时间价值，较合理地反映了投资项目的真正的经济价值，是一个比较好的投资决策指标。

2．IRR（武大2005研，上海交大2005研）答：内部报酬率（IRR）是指使投资方案净现值为零的贴现率。

公司理财第九版罗斯课后案例答案 Case Solutions CorporateFinance1. 案例一：公司资金需求分析问题：一家公司需要资金支持其新项目。

通过分析现金流量，推断该公司是否需要向外部借款或筹集其他资金。

解答：为了确定公司是否需要外部资金，我们需要分析公司的现金流量状况。

首先，我们需要计算公司的净现金流量（净收入加上非现金项目）。

然后，我们需要将净现金流量与项目的投资现金流量进行对比。

假设公司预计在项目开始时投资100万美元，并在项目运营期为5年。

预计该项目每年将产生50万美元的净现金流量。

现在，我们需要进行以下计算：净现金流量 = 年度现金流量 - 年度投资现金流量年度投资现金流量 = 100万美元年度现金流量 = 50万美元净现金流量 = 50万美元 - 100万美元 = -50万美元根据计算结果，公司的净现金流量为负数（即净现金流出），意味着公司每年都会亏损50万美元。

因此，公司需要从外部筹集资金以支持项目的运营。

2. 案例二：公司股权融资问题：一家公司正在考虑通过股权融资来筹集资金。

根据公司的财务数据和资本结构分析，我们需要确定公司最佳的股权融资方案。

解答：为了确定最佳的股权融资方案，我们需要参考公司的财务数据和资本结构分析。

首先，我们需要计算公司的资本结构比例，即股本占总资本的比例。

然后，我们将不同的股权融资方案与资本结构比例进行对比，选择最佳的方案。

假设公司当前的资本结构比例为60%的股本和40%的债务，在当前的资本结构下，公司的加权平均资本成本（WACC）为10%。

现在，我们需要进行以下计算：•方案一：以新股发行筹集1000万美元，并将其用于项目投资。

在这种方案下，公司的资本结构比例将发生变化。

假设公司的股本增加至80%，债务比例减少至20%。

根据资本结构比例的变化，WACC也将发生变化。

新的WACC可以通过以下公式计算得出：新的WACC = (股本比例 * 股本成本) + (债务比例 * 债务成本)假设公司的股本成本为12%，债务成本为8%：新的WACC = (0.8 * 12%) + (0.2 * 8%) = 9.6%•方案二：以新股发行筹集5000万美元，并将其用于项目投资。

第一章公司理财导论1.代理么问题谁拥有公司?描述所有者控制公司管理层的过程。

代理关系在公司的组织形式中存在的主要原因是什?在这种环境下，可能会出现什么样的问题?2.非营利企业的目标假设你是一家非营利企业（或许是非营利医院）的财务经理，你认为什么样的财务管理目标将会是恰当的?3.公司的目标评价下面这句话：管理者不应该只关注现在的股票价值，因为这么做将会导致过分强调短期利润而牺牲长期利润。

4.道德规范和公司目标股票价值最大化的目标可能和其他目标，比如避免不道德或者非法的行为相冲突吗?特别是，你认为顾客和员工的安全、环境和社会的总体利益是否在这个框架之内，或者他们完全被忽略了?考虑一些具体的情形来阐明你的回答。

5.跨国公司目标股票价值最大化的财务管理目标在外国会有不同吗?为什么?6.代理问题假设你拥有一家公司的股票，每股股票现在的价格是25 美元。

另外一家公司刚刚宣布它想要购买这个公司，愿意以每股35 美元的价格收购发行在外的所有股票。

你公司的管理层立即展开对这次恶意收购的斗争。

管理层是为股东的最大利益行事吗?为什么?7.代理问题和公司所有权公司所有权在世界各地都不相同。

历史上，美国个人投资者占了上市公司股份的大多数，但是在德国和日本，银行和其他金融机构拥有上市公司股份的大部分。

你认为代理问题在德国和日本会比在美国更严重吗?8.代理问题和公司所有权近年来，大型金融机构比如共同基金和养老基金已经成为美国股票的主要持有者。

这些机构越来越积极地参与公司事务。

这一趋势对代理问题和公司控制有什么样的启示?9.高管薪酬批评家指责美国公司高级管理人员的薪酬过高，应该削减。

比如在大型公司中，甲骨文的LarryEllison 是美国薪酬最高的首席执行官之一，2004～2008 年收入高达4.29 亿美元，仅2008 年就有1.93 亿美元之多。

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。

第一章1.在所有权形式的公司中,股东是公司的所有者。

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。

较少的私人投资者能减少不同的企业目标。

高比重的机构所有权导致高学历的股东和管理层讨论决策风险项目。

此外,机构投资者比私人投资者可以根据自己的资源和经验更好地对管理层实施有效的监督机制。

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.。

第十八章：杠杆企业的股价与资本预算1、调整的净现值法（APV）如下：（UCF t=无杠杆企业项目第期流向权益所有者的现金流量R0=无杠杆企业项目的资本成本）2、APV 法用权益资本成本折现现金流得到无杠杆项目的价值，然后加上负债的节税现值，得到有杠杆情况下的项目价值；而WACC 法则将UCF 按R WACC折现，而R WACC 低于R0 。

3、FTE 法使用的是LCF，而其它两种方法使用的是UCF。

4、WACC 法在计算现金流量时使用的是无杠杆企业的现金流量，没有包含利息，但是在计算加权平均成本的时候包含了利息成本。

若在计算现金流时要把利息的支付包括进去，可使用FTF 法。

5、无杠杆企业的贝塔值可以用杠杆的贝塔来衡量，它是企业业务风险的衡量标准；另外，企业的金融风险也可以由贝塔值来衡量。

6.a. The maximum price that the company should be willing to pay for the fleet of cars with all-equity funding is the price that makes the NPV of the transaction equal to zero. The NPV equation for the project is:NPV = –Purchase Price + PV[(1 – t C )(EBTD)] + PV(Depreciation Tax Shield)If we let P equal the purchase price of the fleet, then the NPV is:NPV = –P + (1 – .35)($140,000)PVIFA13%,5 + (.35)(P/5)PVIFA13%,5Setting the NPV equal to zero and solving for the purchase price, we find:0 = –P + (1 – .35)($140,000)PVIFA13%,5 + (.35)(P/5)PVIFA13%,5P = $320,068.04 + (P)(0.35/5)PVIFA13%,5 = $320,068.04 + .2462P.7538P = $320,068.04 则P = $424,609.54b. The adjusted present value (APV) of a project equals the net present value of the project if it were funded completely by equity plus the net present value of any financing side effects.In this case, the NPV of financing side effects equals the after-tax present value of the cash flows resulting from the firm‘s debt, so:APV = NPV(All-Equity) + NPV(Financing Side Effects)So, the NPV of each part of the APV equation is:NPV(All-Equity) = –Purchase Price + PV[(1 – t C )(EBTD)] + PV(Depreciation Tax Shield) The company paid $395,000 for the fleet of cars. Because this fleet will be fully depreciated over five years using the straight-line method, annual depreciation expense equals: Depreciation = $395,000/5 = $79,000So, the NPV of an all-equity project is:NPV = –$395,000 + (1 – 0.35)($140,000)PVIFA13%,5 + (0.35)($79,000)PVIFA13%,5NPV = $22,319.49NPV(Financing Side Effects)The net present value of financing side effects equals the after-tax present value of cash flows resulting from the firm‘s debt, so:NPV = Proceeds – Aftertax PV(Interest Payments) – PV(Principal Payments)Given a known level of debt, debt cash flows should be discounted at the pre-tax cost of debt R B. So, the NPV of the financing side effects are:NPV = $260,000 – (1 – 0.35)(0.08)($260,000)PVIFA8%,5 – [$260,000/(1.08)⌒5] = $29,066.93 So, the APV of the project is:APV = NPV(All-Equity) + NPV(Financing Side Effects)APV = $22,319.49 + 29,066.93 = $51,386.427. a. In order to value a firm‘s equity using the flow-to-equity approach, discount the cash flows available to equity holders at the cost of the firm‘s levered equity. The cash flows to equity holders will be the firm‘s net income. Remembering that the company has three stores, we find:Sales $3,600,000COGS 1,530,000G & A costs 1,020,000Interest 102,000EBT $948,000Taxes 379,200NI $568,800Since this cash flow will remain the same forever, the present value of cash flows available to the firm‘s equity holders is a perpetuity. We can discount at the levered cost of equity, so, the value of the company‘s equity is: PV(Flow-to-equity) = $568,800 / 0.19 = $2,993,684.21b. The value of a firm is equal to the sum of the market values of its debt and equity, or:V L = B + SWe calculat ed the value of the company‘s equity in part a, so now we need to calculate the value of debt. The company has a debt-to-equity ratio of 0.40, which can be written algebraically as: B / S = 0.40We can substitute the value of equity and solve for the value of debt, doing so, we find:B / $2,993,684.21 = 0.40 则B = $1,197,473.68So, the value of the company is: V = $2,993,684.21 + 1,197,473.68 = $4,191,157.898. a. In order to determine the cost of the firm‘s debt, we need to find the yield to maturity on its current bonds. With semiannual coupon payments, the yield to maturity in the company‘s bonds is: $975 = $40(PVIFA R%,40) + $1,000(PVIF R%,40) 则R = .0413 or 4.13%Since the coupon payments are semiannual, the YTM on the bonds is:YTM = 4.13%× 2 = 8.26%b. We can use the Capital Asset Pricing Model to find the return on unlevered equity. According to the Capital Asset Pricing Model:R0 = R F + βUnlevered(R M – R F) = 5% + 1.1(12% – 5%) = 12.70%Now we can find the cost of levered equity. According to Modigliani-Miller Proposition II with corporate taxesR S = R0 + (B/S)(R0 – R B)(1 – t C) = .1270 + (.40)(.1270 – .0826)(1 – .34) = .1387 or 13.87% c. In a world with corporate taxes, a firm‘s weighted average cost of capital is equal to:R WACC = [B / (B + S)](1 – t C)R B + [S / (B + S)]R SThe problem does not provide either the debt-value ratio or equity-value ratio. However, the firm‘s debt-equity ratio of is: B/S = 0.40Solving for B: B = 0.4SSubstituting this in the debt-value ratio, we get: B/V = .4S / (.4S + S) = .4 / 1.4 = .29And the equity-value ratio is one minus the debt-value ratio, or: S/V = 1 – .29= .71So, the WACC for the company is: R WACC = .29(1 – .34)(.0826) + .71(.1387)R WACC = .1147 or 11.47%9. a. The equity beta of a firm financed entirely by equity is equal to its unlevered beta. Since each firm has an unlevered beta of 1.25, we can find the equity beta for each. Doing so, we find:North PoleβEquity = [1 + (1 – t C)(B/S)] βUnlevered = [1 + (1 – .35)($2,900,000/$3,800,000](1.25) = 1.87 South PoleβEquity = [1 + (1 – t C)(B/S)]βUnlevered = [1 + (1 – .35)($3,800,000/$2,900,000](1.25) = 2.31b. We can use the Capital Asset Pricing Model to find th e required return on each firm‘s equity. Doing so, we find:North Pole: R S = R F + βEquity(R M – R F) = 5.30% + 1.87(12.40% – 5.30%) = 18.58%South Pole: R S = R F + βEquity(R M – R F) = 5.30% + 2.31(12.40% – 5.30%) = 21.73%10. First we need to find the aftertax value of the revenues minus expenses. The aftertax value is: Aftertax revenue = $3,800,000(1 – .40) = $2,280,000Next, we need to find the depreciation tax shield. The depreciation tax shield each year is: Depreciation tax shield = Depreciation(t C) = ($11,400,000 / 6)(.40) = $760,000Now we can find the NPV of the project, which is:NPV = Initial cost + PV of depreciation tax shield + PV of aftertax revenueTo find the present value of the depreciation tax shield, we should discount at the risk-free rate, and we need to discount the aftertax revenues at the cost of equity, so:NPV = –$11,400,000 + $760,000(PVIFA6%,6) + $2,280,000(PVIFA14%,6) = $1,203,328.43 11. a. The company has a capital structure with three parts: long-term debt, short-term debt, and equity. Since interest payments on both long-term and short-term debt are tax-deductible, multiply the pretax costs by (1 – t C) to determine the aftertax costs to be used in the weighted average cost of capital calculation. The WACC using the book value weights is:R WACC = (w STD)(R STD)(1 – t C) + (w LTD)(R LTD)(1 – t C) + (w Equity)(R Equity)R WACC = ($3 / $19)(.035)(1 – .35) + ($10 / $19)(.068)(1 – .35) + ($6 / $19)(.145)R WACC = 0.0726 or 7.26%b. Using the market value weights, the company‘s WACC is:R WACC = (w STD)(R STD)(1 – t C) + (w LTD)(R LTD)(1 – t C) + (w Equity)(R Equity)R WACC = ($3 / $40)(.035)(1 – .35) + ($11 / $40)(.068)(1 – .35) + ($26 / $40)(.145)R WACC = 0.1081 or 10.81%c. Using the target debt-equity ratio, the target debt-value ratio for the company is:B/S = 0.60 则B = 0.6SSubstituting this in the debt-value ratio, we get: B/V = .6S / (.6S + S) = .6 / 1.6 = .375And the equity-value ratio is one minus the debt-value ratio, or: S/V = 1 – .375 = .625We can use the ratio of short-term debt to long-term debt in a similar manner to find the short-term debt to total debt and long-term debt to total debt. Using the short-term debt to long-term debt ratio, we get: STD/LTD = 0.20 则STD = 0.2LTDSubstituting this in the short-term debt to total debt ratio, we get:STD/B = .2LTD / (.2LTD + LTD) = .2 / 1.2 = .167And the long-term debt to total debt ratio is one minus the short-term debt to total debt ratio, or: LTD/B = 1 – .167 = .833Now we can find the short-term debt to value ratio and long-term debt to value ratio by multiplying the respective ratio by the debt-value ratio. So:STD/V = (STD/B)(B/V) = .167(.375) = .063And the long-term debt to value ratio is:LTD/V = (LTD/B)(B/V) = .833(.375) = .313So, using the target capital structure we ights, the company‘s WACC is:R WACC = (w STD)(R STD)(1 – t C) + (w LTD)(R LTD)(1 – t C) + (w Equity)(R Equity)R WACC = (.06)(.035)(1 – .35) + (.31)(.068)(1 – .35) + (.625)(.145) = 0.1059 or 10.59%d. The differences in the WACCs are due to the different weighti ng schemes. The company‘s WACC will most closely resemble the WACC calculated using target weights since future projects will be financed at the target ratio. Therefore, the WACC computed with target weights should be used for project evaluation12.略13. The adjusted present value of a project equals the net present value of the project under all-equity financing plus the net present value of any financing side effects. First, we need to calculate the unlevered cost of equity. According to Modigliani-Miller Proposition II with corporate taxes: R S = R0 + (B/S)(R0 – R B)(1 – t C).16 = R0 + (0.50)(R0 – 0.09)(1 – 0.40) 则R0 = 0.1438 or 14.38%Now we can find the NPV of an all-equity project, which is:NPV = PV(Unlevered Cash Flows)NPV = –$21,000,000 + $6,900,000/1.1438 + $11,000,000/(1.1438)2 + $9,500,000/(1.1438)3 NPV = –$212,638.89Next, we need to find the net present value of financing side effects. This is equal the aftertax present value of cash flows resulting from the firm‘s debt. So:NPV = Proceeds – Aftertax PV(Interest Payments) – PV(Principal Payments)Each year, an equal principal payment will be made, which will reduce the interest accrued during the year. Given a known level of debt, debt cash flows should be discounted at the pre-tax cost of debt, so the NPV of the financing effects are:NPV = $7,000,000 – (1 – .40)(.09)($7,000,000) / (1.09) – $2,333,333.33/(1.09)– (1 – .40)(.09)($4,666,666.67)/(1.09)⌒2 – $2,333,333.33/(1.09)⌒2– (1 – .40)(.09)($2,333,333.33)/(1.09)⌒3 – $2,333,333.33/(1.09)⌒3 = $437,458.31So, the APV of project is: APV = NPV(All-equity) + NPV(Financing side effects)APV = –$212,638.89 + 437,458.31 = $224,819.4214. a. To calculate the NPV of the project, we first need to find the company‘s WACC. In a world with cor porate taxes, a firm‘s weighted average cost of capital equals:R WACC = [B / (B + S)](1 – t C)R B + [S / (B + S)]R SThe market value of the company‘s equity is:Market value of equity = 6,000,000($20) = $120,000,000So, the debt-value ratio and equity-value ratio are:Debt-value = $35,000,000 / ($35,000,000 + 120,000,000) = .2258Equity-value = $120,000,000 / ($35,000,000 + 120,000,000) = .7742Since the CEO believes its current capital structure is optimal, these values can be used as thetarget weight s in the firm‘s weighted average cost of capital calculation. The yield to maturity of the company‘s debt is its pretax cost of debt. To find the company‘s cost of equity, we need to calculate the stock beta. The stock beta can be calculated as:β= 标准差S,M / 方差M = .036 / .202 = 0.90Now we can use the Capital Asset Pricing Model to determine the cost of equity. The Capital Asset Pricing Model is: R S = R F + β(R M – R F) = 6% + 0.90(7.50%) = 12.75%Now, we can calculate the company‘s WACC, which is:R WACC = [B / (B + S)](1 – t C)R B + [S / (B + S)]R S = .2258(1 – .35)(.08) + .7742(.1275)R WACC = .1105 or 11.05%Finally, we can use the WACC to discount the unlevered cash flows, which gives us an NPV of: NPV = –$45,000,000 + $13,500,000(PVIFA11.05%,5) = $4,837,978.59b. The weighted average cost of capital used in part a will not change if the firm chooses to fund the project entirely with debt. The weighted average cost of capital is based on optimal capital structure weights. Since the current capital structure is optimal, all-debt funding for the project simply implies that the firm will have to use more equity in the future to bring the capital structure back towards the target15. a. Since the company is currently an all-equity firm, its value equals the present value of its unlevered after-tax earnings, discounted at its unlevered cost of capital. The cash flows to shareholders for the unlevered firm are:EBIT $83,000Tax 33,200Net income $49,800So, the value of the company is: V U = $49,800 / .15 = $332,000b. The adjusted present value of a firm equals its value under all-equity financing plus the net present value of any financing side effects. In this case, the NPV of financing side effects equals the after-tax present value of cash flows resulting from debt. Given a known level of debt, debt cash flows should be discounted at the pre-tax cost of debt, so:NPV = Proceeds – Aftertax PV(Interest payments)NPV = $195,000 – (1 – .40)(.09)($195,000) / 0.09 = $78,000So, using the APV method, the value of the company is:APV = V U + NPV(Financing side effects) = $332,000 + 78,000 = $410,000The value of the debt is given, so the value of equity is the value of the company minus the value of the debt, or: S = V – B = $410,000 – 195,000 = $215,000c. According to Modigliani-Miller Proposition II with corporate taxes, the required return of levered equity is:R S = R0 + (B/S)(R0 – R B)(1 – t C)R S = .15 + ($195,000 / $215,000)(.15 – .09)(1 – .40) = .1827 or 18.27%d. In order to value a firm‘s equity using the flow-to-equity approach, we can discount the cash flows available to equity holders at the cost of the firm‘s levered equity. First, we need to calculate the levered cash flows available to shareholders, which are:EBIT $83,000Interest 17,550EBT $65,450Tax 26,180Net income $39,270So, the value of equity with the flow-to-equity method is:S = Cash flows available to equity holders / R S = $39,270 / .1827 = $215,00016.. Since the company is not publicly traded, we need to use the industry numbers to calculate the industry levered return on equity. We can then find the industry unlevered return on equity, and re-lever the industry return on equity to account for the different use of leverage. So, using the CAPM to calculate the industry levered return on equity, we find:R S = R F + β(MRP) = 5% + 1.2(7%) = 13.40%Next, to find the average cost of unlevered equity in the holiday gift industry we can use Modigliani-Miller Proposition II with corporate taxes, so:R S = R0 + (B/S)(R0 – R B)(1 – t C) =.1340 = R0 + (.35)(R0 – .05)(1 – .40)R0 = .1194 or 11.94%Now, we can use the Modigliani-Miller Proposition II with corporate taxes to re-lever the return on equity to account for this company‘s debt-equity ratio. Doing so, we find:R S = R0 + (B/S)(R0 – R B)(1 – t C) = .1194 + (.40)(.1194 – .05)(1 – .40) = .1361 or 13.61% Since the project is financed at the firm‘s target debt-equity ratio, it must be discounted at the company‘s weighted average cost of capital. In a world with corporate taxes, a firm‘s weighted average cost of capital equals: R WACC = [B / (B + S)](1 – t C)R B + [S / (B + S)]R S So, we need the debt-value and equity-value ratios for the company. The debt-equity ratio for the company is: B/S = 0.40 则B = 0.40SSubstituting this in the debt-value ratio, we get: B/V = .40S / (.40S + S) = .40 / 1.40 = .29 And the equity-value ratio is one minus the debt-value ratio, or: S/V = 1 – .29 = .71So, using the capital structure weights, the company‘s WACC is:R WACC = [B / (B + S)](1 – t C)R B + [S / (B + S)]R SR WACC = .29(1 – .40)(.05) + .71(.1361) = .1058 or 10.58%Now we need the project‘s cash flows. The cash flows increase for the first five years before leveling off into perpetuity. So, the cash flows from the project for the next six years are: Year 1 cash flow $80,000.00Year 2 cash flow $84,000.00Year 3 cash flow $88,200.00Year 4 cash flow $92,610.00Year 5 cash flow $97,240.50Year 6 cash flow $97,240.50So, the NPV of the project is:NPV = –$475,000 + $80,000/1.1058 + $84,000/1.1058⌒2 + $88,200/1.1058⌒3 +$92,610/1.1058⌒4 + $97,240.50/1.1058⌒5 + ($97,240.50/.1058)/1.1058⌒5 = $408,125.67。

第五章：净现值和投资评价的其他方法1.如果项目会带来常规的现金流，回收期短于项目的生命周期意味着，在折现率为0 的情况下，NPV 为正值。

折现率大于0 时，回收期依旧会短于项目的生命周期，但根据折现率小于、等于、大于IRR 的情况，NPV 可能为正、为零、为负。

折现回收期包含了相关折现率的影响。

如果一个项目的折现回收期短于该项目的生命周期，NPV 一定为正值。

2.如果某项目有常规的现金流，而且NPV 为正，该项目回收期一定短于其生命周期。

因为折现回收期是用与NPV 相同的折现值计算出来的，如果NPV为正，折现回收期也会短于该项目的生命周期。

NPV 为正表明未来流入现金流大于初始投资成本，盈利指数必然大于1。

如果NPV 以特定的折现率R 计算出来为正值时，必然存在一个大于R 的折现率R’使得NPV 为0，因此，IRR 必定大于必要报酬率。

3.（1）回收期法就是简单地计算出一系列现金流的盈亏平衡点。

其缺陷是忽略了货币的时间价值，另外，也忽略了回收期以后的现金流量。

当某项目的回收期小于该项目的生命周期，则可以接受；反之，则拒绝。

回收期法决策作出的选择比较武断。

（2）平均会计收益率为扣除所得税和折旧之后的项目平均收益除以整个项目期限内的平均账面投资额。

其最大的缺陷在于没有使用正确的原始材料，其次也没有考虑到时间序列这个因素。

一般某项目的平均会计收益率大于公司的目标会计收益率，则可以接受；反之，则拒绝。

（3）内部收益率就是令项目净现值为0 的贴现率。

其缺陷在于没有办法对某些项目进行判断，例如有多重内部收益率的项目，而且对于融资型的项目以及投资型的项目判断标准截然相反。

对于投资型项目，若IRR 大于贴现率，项目可以接受；反之，则拒绝。

对于融资型项目，若IRR 小于贴现率，项目可以接受；反之，则拒绝。

（4）盈利指数是初始以后所有预期未来现金流量的现值和初始投资的比值。

必须注意的是，倘若初始投资期之后，在资金使用上还有限制，那盈利指数就会失效。
