CHAPTER 9RISK ANALYSIS, REAL OPTIONS, AND CAPITAL BUDGETINGAnswers to Concepts Review and Critical Thinking Questions1.Forecasting risk is the risk that a poor decision is made because of errors in projected cash flows. The danger is greatest with a new product because the cash flows are probably harder to predict.2.With a sensitivity analysis, one variable is examined over a broad range of values. With a scenario analysis, all variables are examined for a limited range of values.3.It is true that if average revenue is less than average cost, the firm is losing money. This much of the statement is therefore correct. At the margin, however, accepting a project with marginal revenue in excess of its marginal cost clearly acts to increase operating cash flow.4.From the shareholder perspective, the financial break-even point is the most important. A project can exceed the accounting and cash break-even points but still be below the financial break-even point. This causes a reduction in shareholder (your) wealth.5.The project will reach the cash break-even first, the accounting break-even next and finally the financial break-even. For a project with an initial investment and sales after, this ordering will always apply. The cash break-even is achieved first since it excludes depreciation. The accounting break-even is next since it includes depreciation. Finally, the financial break-even, which includes the time value of money, is achieved.6.Traditional NPV analysis is often too conservative because it ignores profitable options such as the ability to expand the project if it is profitable, or abandon the project if it is unprofitable. The option to alter a project when it has already been accepted has a value, which increases the NPV of the project.7.The type of option most likely to affect the decision is the option to expand. If the country just liberalized its markets, there is likely the potential for growth. First entry into a market, whether an entirely new market, or with a new product, can give a company name recognition and market share. This may make it more difficult for competitors entering the market. 8.Sensitivity analysis can determine how the financial break-even point changes when some factors (such as fixed costs, variable costs, or revenue) change.9.There are two sources of value with this decision to wait. Potentially, the price of the timber can potentially increase, and the amount of timber will almost definitely increase, barring a natural catastrophe or forest fire. The option to wait for a logging company is quite valuable, and companies in the industry have models to estimate the future growth of a forest depending on its age. 10.When the additional analysis has a negative NPV. Since the additional analysis is likely to occur almost immediately, this means when the benefits of the additional analysis outweigh the costs. The benefits of the additional analysis are the reduction in the possibility of making a bad decision. Of course, the additional benefits are often difficult, if not impossible, to measure, so much of this decision is based on experience.Solutions to Questions and ProblemsNOTE: All end of chapter problems were solved using a spreadsheet. Many problems require multiple steps. Due to space and readability constraints, when these intermediate steps are included in this solutions manual, rounding may appear to have occurred. However, the final answer for each problem is found without rounding during any step in the problem.Basic1.a.To calculate the accounting breakeven, we first need to find the depreciation for each year. The depreciation is:Depreciation = $896,000/8 Depreciation = $112,000 per yearAnd the accounting breakeven is:QA = ($900,000 + 112,000)/($38 25) QA = 77,846 unitsb.We will use the tax shield approach to calculate the OCF. The OCF is:OCFbase = (P v)Q FC(1 tc) + tcD OCFbase = ($38 25)(100,000) $900,000(0.65) + 0.35($112,000) OCFbase = $299,200Now we can calculate the NPV using our base-case projections. There is no salvage value or NWC, so the NPV is:NPVbase = $896,000 + $299,200(PVIFA15%,8) NPVbase = $446,606.60To calculate the sensitivity of the NPV to changes in the quantity sold, we will calculate the NPV at a different quantity. We will use sales of 105,000 units. The NPV at this sales level is: OCFnew = ($38 25)(105,000) $900,000(0.65) + 0.35($112,000) OCFnew = $341,450And the NPV is:NPVnew = $896,000 + $341,450(PVIFA15%,8) NPVnew = $636,195.93So, the change in NPV for every unit change in sales is:DNPV/DS = ($636,195.93 446,606.60)/(105,000 100,000) DNPV/DS = +$37.918If sales were to drop by 100 units, then NPV would drop by:NPV drop = $37.918(100) = $3,791.80You may wonder why we chose 105,000 units. Because it doesnt matter! Whatever sales number we use, when we calculate the change in NPV per unit sold, the ratio will be the same. c.To find out how sensitive OCF is to a change in variable costs, we will compute the OCF at a variable cost of $24. Again, the number we choose to use here is irrelevant: We will get the same ratio of OCF to a one dollar change in variable cost no matter what variable cost we use. So, using the tax shield approach, the OCF at a variable cost of $24 is:OCFnew = ($38 24)(100,000) 900,000(0.65) + 0.35($112,000) OCFnew = $364,200So, the change in OCF for a $1 change in variable costs is:DOCF/Dv = ($299,200 364,200)/($25 24) DOCF/Dv = $65,000If variable costs decrease by $5 then, OCF would increase by OCF increase = $65,000*5 = $325,0002.We will use the tax shield approach to calculate the OCF for the best- and worst-case scenarios. For the best-case scenario, the price and quantity increase by 10 percent, so we will multiply the base case numbers by 1.1, a 10 percent increase. The variable and fixed costs both decrease by 10 percent, so we will multiply the base case numbers by .9, a 10 percent decrease. Doing so, we get:OCFbest = ($38)(1.1) ($25)(0.9)(100K)(1.1) $900K(0.9)(0.65) + 0.35($112K) OCFbest = $892,650The best-case NPV is:NPVbest = $896,000 + $892,650(PVIFA15%,8) NPVbest = $3,109,607.54For the worst-case scenario, the price and quantity decrease by 10 percent, so we will multiply the base case numbers by .9, a 10 percent decrease. The variable and fixed costs both increase by 10 percent, so we will multiply the base case numbers by 1.1, a 10 percent increase. Doing so, we get:OCFworst = ($38)(0.9) ($25)(1.1)(100K)(0.9) $900K(1.1)(0.65) + 0.35($112K) OCFworst = 212,350The worst-case NPV is:NPVworst = $896,000 $212,350(PVIFA15%,8) NPVworst = $1,848,882.723.We can use the accounting breakeven equation:QA = (FC + D)/(P v) to solve for the unknown variable in each case. Doing so, we find:(1): QA = 130,200 = (850,000 + D)/(41 30) D = 582,200(2): QA = 135,000 = (3.2M + 1.15M)/(P 56) P = 88.22(3): QA = 5,478 = (160,000 + 105,000)/(105 v) v = 56.624.When calculating the financial breakeven point, we express the initial investment as an equivalent annual cost (EAC). Dividing the in initial investment by the seven-year annuity factor, discounted at 12 percent, the EAC of the initial investment is:EAC = Initial Investment / PVIFA12%,5EAC = £200,000 / 3.60478EAC = £55,481.95Note, this calculation solves for the annuity payment with the initial investment as the present value of the annuity, in other words:PVA = C(1 1/(1 + R)t / R)£200,000 = C1 (1/1.12)5 / .12C = £55,481.95 The annual depreciation is the cost of the equipment divided by the economic life, or:Annual depreciation = £200,000 / 5Annual depreciation = £40,000Now we can calculate the financial breakeven point. The financial breakeven point for this project is: QF = EAC + FC(1 tC) Depreciation(tC) / (P VC)(1 tC) QF = £55,481.95 + £350,000(.75) £40,000(0.25) / (£25 5) (.25) QF = 20,532.13 or about 20,532 units5.If we purchase the machine today, the NPV is the cost plus the present value of the increased cash flows, so:NPV0 = 1,500,000 + 280,000(PVIFA12%,10) NPV0 = 82,062.45We should not purchase the machine today. We would want to purchase the machine when the NPV is the highest. So, we need to calculate the NPV each year. The NPV each year will be the cost plus the present value of the increased cash savings. We must be careful however. In order to make the correct decision, the NPV for each year must be taken to a common date. We will discount all of the NPVs to today. Doing so, we get:Year 1: NPV1 = 1,375,000 + 280,000(PVIFA12%,9) / 1.12 NPV1 = 104,383.88Year 2: NPV2 = 1,250,000 + 280,000(PVIFA12%,8) / 1.122 NPV2 = 112,355.82Year 3: NPV3 = 1,125,000 + 280,000(PVIFA12%,7) / 1.123 NPV3 = 108,796.91Year 4: NPV4 = 1,000,000 + 280,000(PVIFA12%,6) / 1.124 NPV4 = 96,086.55Year 5: NPV5 = 1,000,000 + 280,000(PVIFA12%,5) / 1.125 NPV5 = 5,298.26Year 6: NPV6 = 1,000,000 + 280,000(PVIFA12%,4) / 1.126 NPV6 = 75,762.72The company should purchase the machine two years from now when the NPV is the highest.6.We need to calculate the NPV of the two options, go directly to market now, or utilize test marketing first. The NPV of going directly to market now is:NPV = CSuccess (Prob. of Success) + CFailure (Prob. of Failure)NPV = $20,000,000(0.45) + $5,000,000(0.55)NPV = $11,750,000Now we can calculate the NPV of test marketing first. Test marketing requires a $2 million cash outlay. Choosing the test marketing option will also delay the launch of the product by one year. Thus, the expected payoff is delayed by one year and must be discounted back to year 0. NPV= C0 + CSuccess (Prob. of Success) + CFailure (Prob. of Failure) / (1 + R)tNPV = $2,000,000 + $20,000,000 (0.75) + $5,000,000 (0.25) / 1.15 NPV = $12,130,434.78The company should not go directly to market with the product since that option has lower expected payoff. 7.We need to calculate the NPV of each option, and choose the option with the highest NPV. So, the NPV of going directly to market is: NPV = CSuccess (Prob. of Success) NPV = Rs.1,200,000 (0.55)NPV = Rs.660,000The NPV of the focus group is: NPV = C0 + CSuccess (Prob. of Success) NPV = Rs.120,000 + Rs.1,200,000 (0.70) NPV = Rs.720,000And the NPV of using the consulting firm is:NPV = C0 + CSuccess (Prob. of Success) NPV = Rs.400,000 + Rs.1,200,000 (0.90)NPV = Rs.680,000The firm should conduct a focus group since that option has the highest NPV. 8.The company should analyze both options, and choose the option with the greatest NPV. So, if the company goes to market immediately, the NPV is:NPV = CSuccess (Prob. of Success) + CFailure (Prob. of Failure)NPV = 30,000,000(.55) + 3,000,000(.45)NPV = 17,850,000.00 Customer segment research requires a 1 million cash outlay. Choosing the research option will also delay the launch of the product by one year. Thus, the expected payoff is delayed by one year and must be discounted back to year 0. So, the NPV of the customer segment research is:NPV= C0 + CSuccess (Prob. of Success) + CFailure (Prob. of Failure) / (1 + R)tNPV = 1,000,000 + 30,000,000 (0.70) + 3,000,000 (0.30) / 1.15 NPV = 18,043,478.26Graphically, the decision tree for the project is:StartResearchNo Research18.0435 million at t = 017.85 million at t = 0SuccessFailureSuccessFailure30 million at t = 1(26.087 million at t = 0)3 million at t = 1(2.6087 million at t = 0)30 million at t = 03 million at t = 0The company should undertake the market segment research since it has the largest NPV.9.a.The accounting breakeven is the aftertax sum of the fixed costs and depreciation charge divided by the aftertax contribution margin (selling price minus variable cost). So, the accounting breakeven level of sales is: QA = (FC + Depreciation)(1 tC) / (P VC)(1 tC) QA = ($340,000 + $20,000) (1 0.35) / ($2.00 0.72) (1 0.35)QA = 281,250.00b.When calculating the financial breakeven point, we express the initial investment as an equivalent annual cost (EAC). Dividing the in initial investment by the seven-year annuity factor, discounted at 15 percent, the EAC of the initial investment is:EAC = Initial Investment / PVIFA15%,7EAC = $140,000 / 4.1604 EAC = $33,650.45Note, this calculation solves for the annuity payment with the initial investment as the present value of the annuity, in other words:PVA = C(1 1/(1 + R)t / R)$140,000 = C1 (1/1.15)7 / .15C = $33,650.45 Now we can calculate the financial breakeven point. The financial breakeven point for this project is: QF = EAC + FC(1 tC) Depreciation(tC) / (P VC)(1 tC) QF = $33,650.45 + $340,000(.65) $20,000(.35) / ($2 0.72) (.65) QF = 297,656.79 or about 297,657 units10. When calculating the financial breakeven point, we express the initial investment as an equivalent annual cost (EAC). Dividing the in initial investment by the five-year annuity factor, discounted at 8 percent, the EAC of the initial investment is:EAC = Initial Investment / PVIFA8%,5EAC = ¥300,000 / 3.60478EAC = ¥75,136.94Note, this calculation solves for the annuity payment with the initial investment as the present value of the annuity, in other words:PVA = C(1 1/(1 + R)t / R)¥300,000 = C1 (1/1.08)5 / .08C = ¥75,136.94 The annual depreciation is the cost of the equipment divided by the economic life, or:Annual depreciation = ¥300,000 / 5Annual depreciation = ¥60,000Now we can calculate the financial breakeven point. The financial breakeven point for this project is: QF = EAC + FC(1 tC) Depreciation(tC) / (P VC)(1 tC) QF = ¥75,136.94 + ¥100,000(.66) ¥60,000(0.34) / (¥60 8) (.34) QF = 3,517.98 or about 3,518 unitsIntermediate11.a.At the accounting breakeven, the IRR is zero percent since the project recovers the initial investment. The payback period is N years, the length of the project since the initial investment is exactly recovered over the project life. The NPV at the accounting breakeven is: NPV = I (1/N)(PVIFAR%,N) 1b.At the cash breakeven level, the IRR is 100 percent, the payback period is negative, and the NPV is negative a
