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.

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?。

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?。
Cha08 罗斯公司理财第九版原版书课后习题
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?。
罗斯《公司理财》名校考研(含复试)真题详解(净现值和投资评价的其他方法)【圣才出品】
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 Corporate Finance
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。

罗斯公司理财第九版课后习题答案中文版
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。

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。

Cha03 罗斯公司理财第九版原版书课后习题
1. We explained that differences in firm size make it difficult to compare financial statements, andwe discussed how to form common-size statements to make comparisons easier and more meaningful.2. Evaluating ratios of accounting numbers is another way of comparing financial statementinformation. We defined a number of the most commonly used ratios, and we discussed the famous Du Pont identity.3. We showed how pro forma financial statements can be generated and used to plan for futurefinancing needs.After you have studied this chapter, we hope that you have some perspective on the uses and abuses of financial statement information. You should also find that your vocabulary of business and financial terms has grown substantially.Concept Questions1. Financial Ratio Analysis A financial ratio by itself tells us little about a company becausefinancial ratios vary a great deal across industries. There are two basic methods for analyzing financial ratios for a company: Time trend analysis and peer group analysis. In time trend analysis, you find the ratios for the company over some period, say five years, and examine how each ratio has changed over this period. In peer group analysis, you compare a company’s financial ratios to those of its peers. Why might each of these analysis methods be useful? What does each tell you about the company’s financial health?2. Industry-Specific Ratios So-called “same-store sales” are a very important measure forcompanies as diverse as McDonald’s and Sears. As the name suggests, examining same-store sales means comparing revenues from the same stores or restaurants at two different points in time.Why might companies focus on same-store sales rather than total sales?3. Sales Forecast Why do you think most long-term financial planning begins with salesforecasts? Put differently, why are future sales the key input?4. Sustainable Growth In the chapter, we used Rosengarten Corporation to demonstrate how tocalculate EFN. The ROE for Rosengarten is about 7.3 percent, and the plowback ratio is about 67 percent. If you calculate the sustainable growth rate for Rosengarten, you will find it is only 5.14 percent. In our calculation for EFN, we used a growth rate of 25 percent. Is this possible? (Hint: Yes. How?)5. EFN and Growth Rate Broslofski Co. maintains a positive retention ratio and keeps its debt–equity ratio constant every year. When sales grow by 20 percent, the firm has a negative projected EFN. What does this tell you about the firm’s sustainable growth rate? Do you know, with certainty, if the internal growth rate is greater than or less than 20 percent? Why? What happens to the projected EFN if the retention ratio is increased? What if the retention ratio is decreased? What if the retention ratio is zero?6. Common-Size Financials One tool of financial analysis is common-size financial statements.Why do you think common-size income statements and balance sheets are used? Note that the accounting statement of cash flows is not converted into a common-size statement. Why do you think this is?7. Asset Utilization and EFN One of the implicit assumptions we made in calculating theexternal funds needed was that the company was operating at full capacity. If the company is operating at less than full capacity, how will this affect the external funds needed?8. Comparing ROE and ROA Both ROA and ROE measure profitability. Which one is more usefulfor comparing two companies? Why?9. Ratio Analysis Consider the ratio EBITD/Assets. What does this ratio tell us? Why might it bemore useful than ROA in comparing two companies?Assets and costs are proportional to sales. Debt and equity are not. A dividend of $1,841.40 was paid, and Martin wishes to maintain a constant payout ratio. Next year’s sales are projected to be $30,960. What external financing is needed?5. Sales and Growth The most recent financial statements for Fontenot Co. are shown here:Assets and costs are proportional to sales. The company maintains a constant 30 percent dividend payout ratio and a constant debt–equity ratio. What is the maximum increase in sales that can be sustained assuming no new equity is issued?6. Sustainable Growth If the Layla Corp. has a 15 percent ROE and a 10 percent payout ratio,what is its sustainable growth rate?7. Sustainable Growth Assuming the following ratios are constant, what is the sustainablegrowth rate?Total asset turnover = 1.90Profit margin = 8.1%Equity multiplier = 1.25Payout ratio = 30%8. Calculating EFN The most recent financial statements for Bradley, Inc., are shown here(assuming no income taxes):Assets and costs are proportional to sales. Debt and equity are not. No dividends are paid. Next year’s sales are projected to be $6,669. What is the external financing needed?9. External Funds Needed Cheryl Colby, CFO of Charming Florist Ltd., has created the firm’s proforma balance sheet for the next fiscal year. Sales are projected to grow by 10 percent to $390 million. Current assets, fixed assets, and short-term debt are 20 percent, 120 percent, and 15 percent of sales, respectively. Charming Florist pays out 30 percent of its net income in dividends.The company currently has $130 million of long-term debt and $48 million in common stock par value. The profit margin is 12 percent.1. Construct the current balance sheet for the firm using the projected sales figure.2. Based on Ms. Colby’s sales growth forecast, how much does Charming Florist need inexternal funds for the upcoming fiscal year?3. Construct the firm’s pro forma balance sheet for the next fiscal year and confirm theexternal funds needed that you calculated in part (b).10. Sustainable Growth Rate The Steiben Company has an ROE of 10.5 percent and a payoutratio of 40 percent.1. What is the company’s sustainable growth rate?2. Can the company’s actual growth rate be different from its sustainable growth rate? Whyor why not?3. How can the company increase its sustainable growth rate?INTERMEDIATE (Questions 11–23)11. Return on Equity Firm A and Firm B have debt–total asset ratios of 40 percent and 30percent and returns on total assets of 12 percent and 15 percent, respectively. Which firm has a greater return on equity?12. Ratios and Foreign Companies Prince Albert Canning PLC had a net loss of £15,834 on salesof £167,983. What was the company’s profit margin? Does the fact that these figures are quoted ina foreign currency make any difference? Why? In dollars, sales were $251,257. What was the netloss in dollars?13. External Funds Needed The Optical Scam Company has forecast a 20 percent sales growthrate for next year. The current financial statements are shown here:1. Using the equation from the chapter, calculate the external funds needed for next year.2. Construct the firm’s pro forma balance sheet for next year and confirm the external fundsneeded that you calculated in part (a).3. Calculate the sustainable growth rate for the company.4. Can Optical Scam eliminate the need for external funds by changing its dividend policy?What other options are available to the company to meet its growth objectives?14. Days’ Sales in Receivables A company has net income of $205,000, a profit margin of 9.3percent, and an accounts receivable balance of $162,500. Assuming 80 percent of sales are on credit, what is the company’s days’ sales in receivables?15. Ratios and Fixed Assets The Le Bleu Company has a ratio of long-term debt to total assets of.40 and a current ratio of 1.30. Current liabilities are $900, sales are $5,320, profit margin is 9.4 percent, and ROE is 18.2 percent. What is the amount of the firm’s net fixed assets?16. Calculating the Cash Coverage Ratio Titan Inc.’s net income for the most recent year was$9,450. The tax rate was 34 percent. The firm paid $2,360 in total interest expense and deducted $3,480 in depreciation expense. What was Titan’s cash coverage ratio for the year?17. Cost of Goods Sold Guthrie Corp. has current liabilities of $270,000, a quick ratio of 1.1,inventory turnover of 4.2, and a current ratio of 2.3. What is the cost of goods sold for the company?18. Common-Size and Common–Base Year Financial Statements In addition to common-size financial statements, common–base year financial statements are often used. Common–base year financial statements are constructed by dividing the current year account value by the base year account value. Thus, the result shows the growth rate in the account. Using the following financial statements, construct the common-size balance sheet and common–base year balance sheet for the company. Use 2009 as the base year.Use the following information for Problems 19, 20, and 22:The discussion of EFN in the chapter implicitly assumed that the company was operating at full capacity. Often, this is not the case. For example, assume that Rosengarten was operating at 90 percent capacity. Full-capacity sales would be $1,000/.90 = $1,111. The balance sheet shows $1,800 in fixed assets. The capital intensity ratio for the company isCapital intensity ratio = Fixed assets/Full-capacity sales = $1,800/$1,111 = 1.62This means that Rosengarten needs $1.62 in fixed assets for every dollar in sales when it reaches full capacity. At the projected sales level of $1,250, it needs $1,250 × 1.62 = $2,025 infixed assets, which is $225 lower than our projection of $2,250 in fixed assets. So, EFN is only $565– 225 = $340.19. Full-Capacity Sales Thorpe Mfg., Inc., is currently operating at only 85 percent of fixed assetcapacity. Current sales are $630,000. How much can sales increase before any new fixed assets are needed?20. Fixed Assets and Capacity Usage For the company in the previous problem, suppose fixedassets are $580,000 and sales are projected to grow to $790,000. How much in new fixed assets are required to support this growth in sales?21. Calculating EFN The most recent financial statements for Moose Tours, Inc., appear below.Sales for 2010 are projected to grow by 20 percent. Interest expense will remain constant; the tax rate and the dividend payout rate will also remain constant. Costs, other expenses, current assets, fixed assets, and accounts payable increase spontaneously with sales. If the firm is operating at full capacity and no new debt or equity is issued, what external financing is needed to support the 20 percent growth rate in sales?22. Capacity Usage and Growth In the previous problem, suppose the firm was operating at only80 percent capacity in 2009. What is EFN now?23. Calculating EFN In Problem 21, suppose the firm wishes to keep its debt–equity ratioconstant. What is EFN now?CHALLENGE (Questions 24–30)24. EFN and Internal Growth Redo Problem 21 using sales growth rates of 15 and 25 percent inaddition to 20 percent. Illustrate graphically the relationship between EFN and the growth rate, and use this graph to determine the relationship between them.25. EFN and Sustainable Growth Redo Problem 23 using sales growth rates of 30 and 352. Ratio Analysis Find and download the “Profitability” spreadsheet for Southwest Airlines (LUV)and Continental Airlines (CAL). Find the ROA (Net ROA), ROE (Net ROE), PE ratio (P/E—high and P/E—low), and the market-to-book ratio (Price/Book—high and Price/Book—low) for each company. Because stock prices change daily, PE and market-to-book ratios are often reported as the highest and lowest values over the year, as is done in this instance. Look at these ratios for both companies over the past five years. Do you notice any trends in these ratios? Which company appears to be operating at a more efficient level based on these four ratios? If you were going to invest in an airline, which one (if either) of these companies would you choose based on this information? Why?3. Sustainable Growth Rate Use the annual income statements and balance sheets under the“Excel Analytics” link to calculate the sustainable growth rate for Coca-Cola (KO) each year for the past four years. Is the sustainable growth rate the same for every year? What are possible reasons the sustainable growth rate may vary from year to year?4. External Funds Needed Look up Black & Decker (BDK). Under the “Financial Highlights” linkyou can find a five-year growth rate for sales. Using this growth rate and the most recent income statement and balance sheet, compute the external funds needed for BDK next year.Mini Case: RATIOS AND FINANCIAL PLANNING AT EAST COAST YACHTSDan Ervin was recently hired by East Coast Yachts to assist the company with its short-term financial planning and also to evaluate the company’s financial performance. Dan graduated from college five years ago with a finance degree, and he has been employed in the treasury department of a Fortune 500 company since then.East Coast Yachts was founded 10 years ago by Larissa Warren. The company’s operations are located near Hilton Head Island, South Carolina, and the company is structured as an LLC. The company has manufactured custom midsize, high-performance yachts for clients over this period, and its products have received high reviews for safety and reliability. The company’s yachts have also recently received the highest award for customer satisfaction. The yachts are primarily purchased by wealthy individuals for pleasure use. Occasionally, a yacht is manufactured for purchase by a company for business purposes.The custom yacht industry is fragmented, with a number of manufacturers. As with any industry, there are market leaders, but the diverse nature of the industry ensures that no manufacturer dominates the market. The competition in the market, as well as the product cost, ensures that attention to detail is a necessity. For instance, East Coast Yachts will spend 80 to 100 hours on hand-buffing the stainless steel stem-iron, which is the metal cap on the yacht’s bow that conceivably could collide with a dock or another boat.To get Dan started with his analyses, Larissa has provided the following financial statements. Dan has gathered the industry ratios for the yacht manufacturing industry.1. Calculate all of the ratios listed in the industry table for East Coast Yachts.2. Compare the performance of East Coast Yachts to the industry as a whole. For each ratio,comment on why it might be viewed as positive or negative relative to the industry. Suppose you create an inventory ratio calculated as inventory divided by current liabilities. How do you interpret this ratio? How does East Coast Yachts compare to the industry average?3. Calculate the sustainable growth rate of East Coast Yachts. Calculate external funds needed(EFN) and prepare pro forma income statements and balance sheets assuming growth at precisely this rate. Recalculate the ratios in the previous question. What do you observe?4. As a practical matter, East Coast Yachts is unlikely to be willing to raise external equity capital,in part because the owners don’t want to dilute their existing ownership and control positions.However, East Coast Yachts is planning for a growth rate of 20 percent next year. What are your conclusions and recommendations about the feasibility of East Coast’s expansion plans?5. Most assets can be increased as a percentage of sales. For instance, cash can be increased byany amount. However, fixed assets often must be increased in specific amounts because it is impossible, as a practical matter, to buy part of a new plant or machine. In this case a company has a “staircase” or “lumpy” fixed cost structure. Assume that East Coast Yachts is currently producing at 100 percent of capacity. As a result, to expand production, the company must set up an entirely new line at a cost of $30 million. Calculate the new EFN with this assumption. What does this imply about capacity utilization for East Coast Yachts next year?。
公司理财罗斯第九版课后习题答案
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 FVA. The equation to find the FVA 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: PVA = $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 Value Interest Factor PVIFA R,t = ({1 – [1/(1 + r)] t } / r ) which stands for Present Value 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 the semiannual 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) t 2.1570 = 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(PVIFA 3.5%,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(PVIF 3.5%,40 ) = $5,051.45 CH8 4，18，20，22，24 4. 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 priceof 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 Year 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 )] P 0 = [$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 Year 3 since the dividend growth rate is constant after the third dividend. The price of the stock in Year 3 will be the dividend in Year 4, divided by the required return minus the constant dividend growth rate. So, the price in Year 3 will be: 6 / 17 P 3 = $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 Year 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 Year 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: Value today of Year 1 cash flow = $4,200/1.14 = $3,684.21 Value today of Year 2 cash flow = $5,300/1.14 2 = $4,078.18 Value today of Year 3 cash flow = $6,100/1.14 3 = $4,117.33 V alue today of Year 4 cash flow = $7,400/1.14 4 = $4,381.39 To find the 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 Year 1 and Year 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 Year 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: Average net income = ($1,938,200 + 2,201,600 + 1,876,000 + 1,329,500) / 4 = $1,836,325 And the average book value is: Average book value = ($15,000,000 + 0) / 2 = $7,500,000 So, the AAR for this project is: AAR = Average net income / Average 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)配套题库【名校考研真题-概念题】
三、概念题1．现金流量（cash flow）[中央财大2003研；首都经贸大学1997研]答：现金流量是指某一段时期内企业现金流入和流出的数量。
如企业销售商品、提供劳务、出售固定资产、向银行借款等取得现金，形成企业的现金流入；购买原材料、接受劳务、购建固定资产、对外投资、偿还债务等支付现金，形成企业的现金流出。
现金流量信息能够表明企业经营状况是否良好、资金是否紧缺、企业偿付能力大小，从而为投资者、债权人、企业管理者提供非常有用的信息。
现金流量一般可以分为三类：经营活动产生的现金流量、投资活动产生的现金流量、筹资活动产生的现金流量。
现金流量通常包括现金等价物的增减变动。
2．ROE[中央财大2010研]答：ROE是return on equity的缩写，即权益收益率，是净利润与总权益的比率，反映每1元股东资本赚取的净利润，可以衡量企业的总体盈利能力。
计算公式为：由于提高股东利益是企业的目标，所以，在会计意义上，ROE是最终的业绩衡量指标。
3．长期财务计划[浙江财经学院2011金融硕士]答：长期财务计划主要是指预算期在一年以上的计划，一般为企业经营战略预算。
企业长期财务计划是企业经营过程各个方面的资金变动的综合反映。
广义上的长期财务规划还包括销售预算、生产预算、销售成本预算、直接材料成本预算、直接人工成本预算、制造费用预算、管理费用预算等。
长期财务计划按照计划的编制方法可以分为固定预算、弹性预算、零基预算、滚动预算等。
4．净现值（net present value）[南京大学2004研；首都经贸大学2005研]答：净现值（net present value，NPV）是指投资项目投入使用后的净现金流量，按资本成本或企业要求达到的报酬率即适当贴现率折算为现值，减去初始投资以后的余额（如果投资期超过一年，则应是减去初始投资的现值以后的余额）。
其计算公式为：-C。
其中NCF t为第t期净现金流，r为贴现率，C为初始投资额。

罗斯《公司理财》（第9版）笔记和课后习题详解第1章公司理财导论1.1复习笔记公司的首要目标——股东财富最大化决定了公司理财的目标。
公司理财研究的是稀缺资金如何在企业和市场内进行有效配置，它是在股份有限公司已成为现代企业制度最主要组织形式的时代背景下，就公司经营过程中的资金运动进行预测、组织、协调、分析和控制的一种决策与管理活动。
从决策角度来讲，公司理财的决策内容包括投资决策、筹资决策、股利决策和净流动资金决策；从管理角度来讲，公司理财的管理职能主要是指对资金筹集和资金投放的管理。
公司理财的基本内容包括：投资决策（资本预算）、融资决策（资本结构）、短期财务管理（营运资本）。
1．资产负债表资产负债表是总括反映企业某一特定日期财务状况的会计报表，它是根据资产、负债和所有者权益之间的相互关系，按照一定的分类标准和一定的顺序，把企业一定日期的资产、负债和所有者权益各项目予以适当排列，并对日常工作中形成的大量数据进行高度浓缩整理后编制而成的。
资产负债表可以反映资本预算、资本支出、资本结构以及经营中的现金流量管理等方面的内容。
2．资本结构资本结构是指企业各种资本的构成及其比例关系，它有广义和狭义之分。
广义资本结构，亦称财务结构，指企业全部资本的构成，既包括长期资本，也包括短期资本（主要指短期债务资本）。
狭义资本结构，主要指企业长期资本的构成，而不包括短期资本。
通常人们将资本结构表示为债务资本与权益资本的比例关系（D/E）或债务资本在总资本的构成（D/A）。
准确地讲，企业的资本结构应定义为有偿负债与所有者权益的比例。
资本结构是由企业采用各种筹资方式筹集资本形成的。
筹资方式的选择及组合决定着企业资本结构及其变化。
资本结构是企业筹资决策的核心问题。
企业应综合考虑影响资本结构的因素，运用适当方法优化资本结构，从而实现最佳资本结构。
资本结构优化有利于降低资本成本，获取财务杠杆利益。
3．财务经理财务经理是公司管理团队中的重要成员，其主要职责是通过资本预算、融资和资产流动性管理为公司创造价值。

第5章净现值和投资评价的其他方法
一、概念题
1．调整的内部收益率（modified IRR，MIRR）
答：调整的内部收益率是指使投资成本的现值等于项目产生收益现值的贴现率。
用公式可以表示为：
式中，COF t为t时刻的现金流出量；CIF t为t时刻的现金流入量；k为适当贴现率，MIRR为调整的内部收益率。
2．内部收益率的基本法则（basic IRR rule）
答：内部收益率的基本法则是：若内部收益率大于折现率，项目可以接受；若内部收益率小于折现率，项目不能接受。
3．互斥项目（mutually exclusive investments）
答：互斥项目，就是存在相互排斥关系的项目，对其接受或者放弃的决策受其他项目投资决策的影响。
比如可以选择A也可以选择B，或者是两者同时放弃，但不能同时采纳项目A和项目B。
4．资本配置（capital rationing）
答：资本配置是指在资本不足以支付所有净现值为正的项目的情况下进行投资决策时对资本的分配。
比如，某公司的项目之间相互独立，公司只有2000万美元可供投资。
由于项目A需要初始投资2000万美元，因此公司一旦选择了项目A就不能再选择其他项目。
而项目B和C都只需要1000万美元的初始投资，这两个项目就可以同时采纳。
也就是说，有限的资本使得公司要么选择项目A，要么选择项目B和C。
在资本有限的情况下，决策者不能仅仅根据单个项目的净现值进行排序，还应根据现值和初始投资的比值进行排序（即盈利指数法则）。
另外，capital rationing在有些译著中也翻译为“资本约束”，偏重强调资本不足或资本有限本身对投资决策的“约束”。
5．净现值法（NPV rule）
答：净现值法是指通过计算和比较不同投资项目的净现值来选择最佳投资方案的一种决策方法。
净现值指投资项目投入使用后的净现金流量，按资本成本或企业要求达到的报酬率折算为现值，减去初始投资以后的余额。
用公式可以表示为：
其中，NPV为净现值；NCF t为第t年的净现金流量；k为适当贴现率；n为项目预计使用年限；C为初始投资额。
净现值法的决策法则是：选择净现值为正的项目，放弃净现值为负的项目；两个或多个项目的净现值均为正时，选择净现值最大的项目。
6．折现回收期法（discounted payback period method）
答：折现回收期法是指先对整个项目周期的现金流量进行折现，然后求出达到初始投资所需要的折现现金流量的时限长短，最后选择折现现金流量时限小于目标时限项目的投资决策方法。
简而言之，初始投资的折现回收期就是针对这些折现后现金流量的回收期。
7．回收（payback）
答：回收是指企业投入资金后，通过经营，陆续收回初始投资的过程。
回收期法就是按照初始投资回收的期限（即回收期）与目标回收期对比，作出项目选择决策的一种方法。
8．增量内部收益率（incremental IRR）
答：增量内部收益率是增量现金流的内部收益率，即使金额相对较大预算所增加的投资等于增量现金流现值的贴现率。
它是内部收益率法的一种扩展或体现，基本原理与内部收益率相似，用公式表示为：
其中，ICF t为第t期的增量现金流；IIRR为增量内部收益率；C为预算较大项目超过预算较小项目的初始投资额。
9．回收期法（payback period rule）
答：回收期法是指将能收回初始投资的期限与目标回收期相比较，作出投资决策的方法。
投资回收期是回收初始投资所需要的时间，一般以年为单位。
投资回收期的计算，因每年的营业净现金流量（NCF）是否相等而有所不同。
如果每年的营业净现金流量相等，则投资回
收期可用公式计算：投资回收期＝初始投资额/每年NCF。
如果每年NCF不相等，那么，计算回收期要根据每年年末尚未回收的投资额加以确定。
回收期法的决策法则：运用回收期法进行互斥项目投资决策时，应优先选择回收期短的方案；若进行单个项目选择是否投资决策时，则必须设置基准投资回收期T C。
当计算的回收期小于等于T C，则项目可以接受；当计算的回收期大于T C，则应予以拒绝。
10．独立项目（independent project）
答：独立项目，就是对其接受或者放弃的决策不受其他项目投资决策影响的投资项目。
11．盈利指数（profitability index）
答：盈利指数是初始投资以后所有预期未来现金流量的现值和初始投资的比值。
盈利指数可以表示为：盈利指数（PI）=
盈利指数法的决策法则是：在只有一个备选项目的采纳与否决策中，盈利指数大于或等于1时采纳，否则拒绝该方案。
在有多个互斥项目的选择决策中，应采用获利指数超过1最多的投资项目。
12．内部收益率（internal rate of return）
答：内部收益率（IRR）是指能够使未来现金流入量现值等于未来现金流出量现值的贴现率，或者说是使投资方案净现值为零的贴现率。
内部收益率用公式表示为：
内部收益法的基本法则是：若内部收益率大于资本成本或基准贴现率，项目可以接受；
若内部收益率小于资本成本或基准贴现率，项目不能接受。
13．价值可加性（value-additivity）
答：价值的可加性是指计算出个别投资计划所创造的价值后，不同投资计划的组合所创造的总价值（以V表示）等于个别投资计划所创造价值的加总。
用公式可以表示为：
其中，V j为个别计划j所创造的价值，。
如果投资计划评估法不满足价值可加性，表示互斥型投资计划的评估结果受到其它独立型投资计划评估结果的影响，两者无法分开独立评估。
如果投资计划评估法符合价值可加性，当投资决策者评估不同的计划组合时，不需重新计算不同组合所创造的总价值，而仅对这组合中个别计划所创造出来的价值加总即可。
二、复习题
1．回收期与净现值如果某项目会带来常规的现金流，而且其回收期短于该项目的生命周期，你可以明确地说出该项目净现值的代数符号吗?为什么?如果该项目的折现回收期短于该项目的生命周期，此时的情况又是怎么样?请解释。
答：假设常规的现金流，投资回收期比该项目的生命周期短只是意味着在零折现率下净现值为正。
如果折现率大于零，投资回收期仍低于该项目的生命周期，但净现值仍可以是正、零或负，这取决于折现率小于、等于或大于回报率。
折现回收期包括了贴现率的影响。
如果一个项目的折现回收期比该项目的生命周期短，它的净现值必然为正。
2．净现值假设某项目有常规的现金流，而且其净现值为正。
根据这个条件，你对该项目的回收期了解多少?折现回收期呢?盈利指数呢?内部收益率呢?请解释。
答：假设某项目有常规的现金流，而且其净现值为正，则当折现率为零的时候其净现值也为正，因此，投资回收期必然比整个项目生命周期短。
由于贴现回收是以相同的折现率计算的净现值，如果净现值为正，投资折现回收期必然低于该项目的生命周期。
如果净现值为正，那么未来现金流的现值大于初始投资成本，因此，盈利指数大于1。
如果净现值是在一定的折现率下为正，且NPV为零，则折现率会较大，因此，内部收益率必然大于贴现率。
3．比较投资标准对下列的投资准则下定义并讨论其潜在的缺陷。
根据你的定义，阐述如何根据这些标准来接受或拒绝某个独立的项目。
（1）回收期
（2）平均会计收益率
（3）内部收益率
（4）盈利指数
（5）净现值
答：（1）投资回收期仅仅是一系列现金流的会计收支平衡点。
要真正计算投资回收期，假定发生的任何现金流在一定时期内整个周期内连续，并不是在某一时点上。
回收期只是一个时点，在这个时点上，所有的初始投资刚好全部收回。
根据回收期的原理，如果项目的回收期在预计期限之前则接受该项目，否则，拒绝该项目。
投资回收期决策方法最严重的问题是，它忽略了货币的时间价值。
此外，没有一个科学可行的方法来确定回收期的最后期限。
一般来说投资回收期方法适用于短期项目，它完全忽略回收期之后的现金流。
（2）平均会计收益法是对一个项目的会计业绩的平均计算，根据资产负债表对该项目。
