• This example will be used for each of the decision rules so that the students can compare the different rules and see that conflicts can arise. This illustrates the importance of recognizing which decision rules provide the best information for making decisions that will increase owner wealth.

• The payback period is year 3 if you assume that the cash flows occur at the end of the year as we do with all of the other decision rules. If we assume that the cash flows occur evenly throughout the year, then the project pays back in 2.34 years.
• The answer to all of these questions is no.
• The example in the book uses straight line depreciation to a zero salvage; that is why you can take the initial investment and divide by 2. If you use MACRS, you need to compute the BV in each period and take the average in the standard way.
• This example will be used for each of the decision rules so that the students can compare the different rules and see that conflicts can arise. This illustrates the importance of recognizing which decision rules provide the best information for making decisions that will increase owner wealth.
• Students may ask where you came up with the 25%, point out that this is one of the drawbacks of this rule. There is no good theory for determining what the return should be. We generally just use some rule of thumb.
• The answer to all of these questions is no. In fact, this rule is even worse than the payback rule in that it doesn’t even use cash flows for the analysis. It uses net income and book value.

• Many of the financial calculators will compute the IRR as soon as it is pressed; others require that you press compute.
• The answer to all of these questions is yes, although it is not always as obvious. The IRR rule accounts for time value because it is finding the rate of return that equates all of the cash flows on a time value basis. The IRR rule accounts for the risk of the cash flows because you compare it to the required return, which is determined by the risk of the project. The IRR rule provides an indication of value because we will always increase value if we can earn a return greater than our required return. We should consider the IRR rule as our primary decision criteria, but as we will see, it has some problems that the NPV does not have. That is why we end up choosing the NPV as our ultimate decision rule.
• You should point out, however, that if you get a very large IRR that you should go back and look at your cash flow estimation again. In competitive markets, extremely high IRRs should be rare.
• So what should we do – we have two rules that indicate to accept and two that indicate to reject.
• As long as we do not have limited capital, we should choose project A. Students will often argue that you should choose B because then you can invest the additional \$100 in another good project, say C. The point is that if we do not have limited capital, we can invest in A and C and still be better off. If we have limited capital, then we will need to examine what combinations of projects with A provide the highest NPV and what combinations of projects with B provide the highest NPV. You then go with the set that will create the most value. If you have limited capital and a large number of mutually exclusive projects, then you will want to set up a computer program to determine the best combination of projects within the budget constraints. The important point is that we DO NOT use IRR to choose between projects regardless of whether or not we have limited capital.
• Even though payback and AAR should not be used to make the final decision, we should consider the project very carefully if they suggest rejection. There may be more risk than we have considered or we may want to pay additional attention to our cash flow estimations. Sensitivity and scenario analysis can be used to help us evaluate our cash flows. The fact that payback is commonly used as a secondary criteria may be because short paybacks allow firms to have funds sooner to invest in other projects without going to the capital markets
• Payback period = 4 years NPV = -2758.72 IRR = 7.93%

1. 1. Net Present Value And Other Investment Criteria Chapter 8 TINKU IBMR - H
2. 2. 2 Topics 1. First Look at Capital Budgeting 2. Investment Criteria: 1. Net Present Value √ 2. Payback Rule ≈ 3. Accounting Rates Of Return ≈ 4. Internal Rate Of Return ≈ 5. The Profitability Index ≈
3. 3. 3 Financial Management  Goal Of Financial Management:  Increasing the value of the equity  Capital Budgeting:  Acquire long-term assets  Because long-term assets:  Determine the nature of the firm  Are hard decisions to reverse  They are the most important decisions for the financial manager  Selecting Assets  Whish assets to invest in?  There are many options.  Which do we pick?
4. 4. 4 Good Decision Criteria For Capital Budgeting  We need to ask ourselves the following questions when evaluating decision criteria  Does the decision rule adjust for the time value of money?  Does the decision rule adjust for risk?  Does the decision rule provide information on whether we are creating value for the firm?
5. 5. Net Present Value = NPV  The difference between the market value and it’s cost = Value Added.  Example:  Point of View = Asset Buyer  If:  Cost = -\$200,000  Market Value (Present Value Future Cash Flows) = \$201,036  NPV = \$201,036 - \$200,000 = \$1,036  We examine a potential investment in light of its likely effect on the price of the firm’s shares  NPV/(# of shares outstanding) 5
6. 6. 6 NPV  If there is a market for assets similar to the one we are considering investing in, we use that market and our decision making is simplified  When we cannot observe a market price for at least a roughly comparable investment, capital budgeting is made difficult… then we use: Discounted Cash Flow Valuation (DCF) to get our NPV  DCF gives us an estimate of market value.
7. 7. Synonyms Discounted Cash Flow Valuation (DCF) Net Present Value (NPV) 7
8. 8. Synonyms Investment = Project = Asset 8
9. 9. 9 Rules for DCF or NPV 1. The first step is to estimate the expected future cash flows (Chapter 9) 2. The second step is to estimate the required return for projects (investments) of this risk level (Chapter 10, 11) 3. The third step is to find the present value of the cash flows and subtract the initial investment (Chapter 8)
10. 10. 10 Ne Di Va Discount Rate = Market Rate = Required Rate Of Return = RRR Period Discount Rate
11. 11. NPV/DCF Example 1 & 2:  Should you invest in a short term project that will cost us \$200,000 to launch and will yield these cash flows (Required Rate of Return= 15%): 11 Cash Flow 0 (Cost) -\$200,000.00 Cash Flow 1 \$100,000.00 Cash Flow 2 \$90,000.00 Cash Flow 3 \$70,000.00
12. 12. NPV/DCF Method Used In Earlier Chapters Example 1: 12
13. 13. NPV Excel Function & Formula NPV Function: =NPV(rate,value1,value2…) ⃰ rate = Period RRR (Discount) = i/n. ⃰ value1 = Range of cells with cash flows. ⃰ Cash flows must happen at the end of each period. ⃰ Cash flows start at time 1. ⃰ Never include cash flows at time 0 (zero). ⃰ Cash flows do not have to be equal in amount. ⃰ Time between each cash flow must be the same. NPV Formula when cost is at time 0: =NPV(rate,value1,value2…) - Cost 13
14. 14. NPV/DCF Method Used This Chapter Example 2: 14
15. 15. 15 Net Present Value (NPV) = Discounted Cash Flow Valuation (DCF)  The process of valuing an investment (project) by discounting its future cash flows  Decision Rule:  NPV > 0  Accept Project  NPV < 0  Reject Project  NPV = 0  Indifferent (RRR = IRR) Create value for stockholder Search for capital budget projects That yield positive NPV value added There are no guarantees that our estimates are correct
16. 16. NPV / DCF Example 3: 16
17. 17. Pro Dif 17 Annual RRR (Discount) + NPV: Accept 5% 29,576 6% 27,070 7% 24,647 8% 22,303 9% 20,035 10% 17,840 11% 15,714 12% 13,654 13% 11,658 14% 9,723 15% 7,847 16% 6,027 17% 4,260 18% 2,545 19% 880 20% -738 21% -2,310 22% -3,838 23% -5,324
18. 18. Profile of NPV at Different Rates 18
19. 19. 19 We Have Just Talked About NPV  Investment Criteria: 1. Net Present Value √ 2. Payback Rule ≈ 3. Accounting Rates Of Return ≈ 4. Internal Rate Of Return ≈ 5. The Profitability Index ≈  Let’s look at one example and compare all these methods
20. 20. 20 Data For Example 4  You are looking at a new project and you have estimated these numbers: CF0 -160,000.00 CF1 60,000.00 CF2 70,000.00 CF3 90,000.00 Net Income 1 13,000.00 Net Income 2 25,000.00 Net Income 3 20,000.00 Your required return for assets of this risk 15% Average Book Value 90,000.00
21. 21. Example 4: Computing NPV for The Project: 21
22. 22. 22 Advantages of NPV Rule  Rule adjusts for the time value of money  Rule adjusts for risk (RRR - Discount Rate)  Rule provides information on whether we are creating value for the firm
23. 23. 23 Payback Rule  Payback Period  The amount of time required for an investment to generate cash flows to recover its initial costs  Computation  Estimate the cash flows  Determine # of years Required to get “paid back”.  Subtract the future cash flows from the initial cost until the initial investment has been recovered Accept Investment Payback Period Pre-specified # of Years <
24. 24. 24 Data For Example 5  You are looking at a new project and you have estimated these numbers: CF0 -160,000.00 CF1 60,000.00 CF2 70,000.00 CF3 90,000.00 Net Income 1 13,000.00 Net Income 2 25,000.00 Net Income 3 20,000.00 Your required return for assets of this risk 15% Average Book Value 90,000.00
25. 25. 25 Example 5: Computing Payback For The Project  Assume we will accept the project if it pays back within two years.  Year 1: 160,000 – 60,000 = 100,00 still to recover  Year 2: 100,000 – 70,000 = 30,000 still to recover  Do we accept or reject the project?  Reject. The project did not pay back within 2 years.
26. 26. Example 5 continued: 26
27. 27. 27 Decision Criteria Test - Payback  Does the payback rule account for the time value of money?  Does the payback rule account for the risk of the cash flows?  Does the payback rule provide an indication about the increase in value?  Should we consider the payback rule for our primary decision criteria?
28. 28. 28 Advantages & Disadvantages of Payback  Advantages  Easy to understand  Cost to do this analysis is minimal – good for small investment decisions  Adjusts for uncertainty of later cash flows (gets rid of them)  Biased towards liquidity (tends to favor investments that free up cash for other uses more quickly)  Disadvantages  Ignores the time value of money  Fails to consider risk differences  Risky or very risky projects are treated the same  Requires an arbitrary cutoff point  Ignores cash flows beyond the cutoff date  Biased against long-term projects, such as research and development, and new projects  Does not guarantee a single answer  Does not ask the right question: Does it increase equity value?  You have to estimate the cash flows any way, so why not take the extra time to calculate NPV?
29. 29. Problems with Payback Rule: 29 Years Required to Pay Back Investment = 2 Year Pro A Pro B Pro C 0 -\$250 \$250 -\$250 1 100 100 100 2 100 100 200 3 -250 100 4 250 100 Accept or Reject? Yes, but is it year 2 or 4? No. Because only \$200 by year 2. Yes. Because \$300 Cash In by year 2. Problems: We get 2 answers Ignores cash flows after year 2. This project has a negative NPV - ignores time value of \$. NPV = \$535.50 -\$11.81 Required Return: 0.15
30. 30. 30 Average Accounting Return = AAR  There are many different definitions for Average Accounting Return.  Here is one:  Here is another:  Calculate (Return On Assets = ROA) for each year and then average the ROAs. Average Net Income Average Book Value = AAR
31. 31. Average Accounting Return = AAR  Steps in calculating AAR: 1. Estimate All Revenue and Expenses over the life of the asset. 2. Calculate the Net Income for each year. 3. Estimate Book Value over life of asset.  Note that the average book value depends on how the asset is depreciated. 1. Decide on target cutoff AAR rate 2. Decision Rule: Accept the project if the calculated AAR > cutoff AAR rate. 31
32. 32. 32 Average Book Value =  When Straight Line Depreciation is used: (Cost + Salvage)/2  When a Non- Straight Line Depreciation is used: (BV0 + BV1 +…BVt)/(t+1)
33. 33. 33 Data For Example 6  You are looking at a new project and you have estimated these numbers: CF0 -160,000.00 CF1 60,000.00 CF2 70,000.00 CF3 90,000.00 Net Income 1 13,000.00 Net Income 2 25,000.00 Net Income 3 20,000.00 Your required return for assets of this risk 15% Average Book Value 90,000.00
34. 34. 34 Com Exa Year 1 Year 2 Year 3 Revenue \$80,000 \$70,000 \$65,000 Expenses (including Depreciation and Tax) \$67,000 \$45,000 \$45,000 Net Income \$13,000 \$25,000 \$20,000 Average Net Income \$19,333 =AVERAGE(B4:D4) Original Cost \$180,000 Salvage \$0 Years 3 Striaght Line Deprectaion \$60,000 =(B8-B9)/B10 Time 0 Time 1 Time 2 Time 3 Book Value = Historical Cost - Accumulated Depreication \$180,000 \$120,000 \$60,000 \$0 Average Book Value \$90,000 =AVERAGE(B14:E14) Average Book Value \$90,000 =B8/2 AAR 0.214814815 =B6/B17 Target AAR 0.25 Decision: Reject Project
35. 35. 35 Decision Criteria Test - AAR  Does the AAR rule account for the time value of money?  Does the AAR rule account for the risk of the cash flows?  Does the AAR rule provide an indication about the increase in value?  Should we consider the AAR rule for our primary decision criteria?
36. 36. 36 Advantages and Disadvantages of AAR  Advantages  Easy to calculate  Needed information will usually be available  Disadvantages  Not a true rate of return; time value of money is ignored  Uses an arbitrary benchmark cutoff rate  Based on accounting net income and book values, not cash flows and market values
37. 37. NPV Profile 37
38. 38. Solve For Rate  Remember:  Chapter 5 (Annuities and Multiple Cash Flows)  Chapter 6 (Bonds)  We learned that we can solve for rate.  For Annuities or Bonds we were able to look at cash flows and determine the rate.  Chapter 8 (Multiple Cash Flows for Buying Assets)  Just as YTM was “internal rate” of cash flows for bonds, IRR will be “internal rate” of cash flows for capital budgeting.  We solve for the rate at which the NPV is zero and that becomes the hurdle rate between + NPV and – NPV. 38
39. 39. IRR = Internal Rate of Return  To Understand What IRR means, build a NPV Profile and look for the rate at which NPV = \$0  This tells you the rate of return for the cash flows from the project. Project Cash Flows CF0 -160,000.00 CF1 60,000.00 CF2 70,000.00 CF3 90,000.00 Required Rate Return 0.15 RRR NPV 14.00% 7,241.74 14.50% 5,750.17 15.00% 4,280.43 15.50% 2,832.09 16.00% 1,404.73 16.50% 0.00 17.00% -1,386.63 17.50% -2,753.47 18.00% -4,100.89 18.50% -5,429.27 19.00% -6,738.96 0) 39
40. 40. IRR = Internal Rate of Return IRR = Rate at Which NPV = \$0 40 All RRR below IRR, add value (+NPV) All RRR above IRR, subtract value (-NPV) 0)
41. 41. 41 IRR = Internal Rate of Return =“Break Even Rate”  Definition: Rate that makes the NPV = \$0  Decision Rule:  Most important alternative to NPV.  It is often used in practice and is intuitively appealing.  Calculation based entirely on the estimated cash flows and is independent of interest rates found elsewhere  Formula inputs are cash flows only! Accept Investment IRR RRR >
42. 42. IRR Excel Function IRR Function: =IRR(values,guess) ⃰ values = range of cells with cash flows. Cash out is negative, cash in is positive. Range of values must contain at least one positive and one negative value. ⃰ Guess is not required. But if you get a #NUM! error, try different guesses – ones you think might be close. ⃰ Cash flows must happen at the end of each period. ⃰ Cash flows start at time 0. ⃰ Cash flows do not have to be equal in amount. ⃰ Time between each cash flow must be the same. ⃰ IRR gives you the period rate. If you give it annual cash flows, it gives you annual rate, if you give it monthly cash flows, it gives you monthly rate. ⃰ **Don’t use IRR for investments that have non-conventional cash flows (cash flow other than time 0 is negative) or the investments are mutually exclusive alternatives and initial cash flows are substantially different or timing are substantially different. 42
43. 43. 43 Data For Example 7  You are looking at a new project and you have estimated these numbers: CF0 -160,000.00 CF1 60,000.00 CF2 70,000.00 CF3 90,000.00 Net Income 1 13,000.00 Net Income 2 25,000.00 Net Income 3 20,000.00 Your required return for assets of this risk 15% Average Book Value 90,000.00
44. 44. 44 Computing IRR For The Project Example 7:  Formula Inputs are cash flows – that’s it!  If you do not have Excel or a financial calculator, then this becomes a trial and error process.
45. 45. Trial And Error Process: Build Profile And “Zero In On” the IRR. 45 Project Cash Flows CF0 -1,000.00 CF1 1,200.00 Solve for directly when exponent is 4 or less (But no need to). NPV = -CF0 + CF1/(1+IRR) 0 = -1,000 + 1,200/(1+IRR) 1,000 = 1,200/(1+IRR) 1 + IRR = 1,200/1,000 IRR = 1,200/1,000 -1 IRR = 0.2 Project Cash Flows CF0 -160,000.00 CF1 60,000.00 CF2 70,000.00 CF3 90,000.00 Required Rate Return 0.15 Increment 0.005 RRR (Discount) + NPV 14.0% 7,241.74 14.5% 5,750.17 15.0% 4,280.43 15.5% 2,832.09 16.0% 1,404.73 16.5% -2.05 17.0% -1,388.65 17.5% -2,755.46 18.0% -4,102.85 18.5% -5,431.20
46. 46. 46 Decision Criteria Test - IRR  Does the IRR rule account for the time value of money?  Does the IRR rule account for the risk of the cash flows?  Does the IRR rule provide an indication about the increase in value?  Should we consider the IRR rule for our primary decision criteria?  No! Because of two circumstances…
47. 47. 47 Advantages of IRR  Knowing a return is intuitively appealing.  It is a simple way to communicate the value of a project to someone who doesn’t know all the estimation details.  If the IRR is high enough, you may not need to estimate a required return, which is often a difficult task.  In the working world, many people use IRR.
48. 48. 48 Summary of Decisions For The Project Summary Net Present Value Accept Payback Period Reject Average Accounting Return Reject Internal Rate of Return Accept
49. 49. Define Mutually Exclusive  A situation were taking one project prevents you from taking another project.  Ex: With the land, you can build a farm or a factory, not both.  Not Both. Independent  Taking one project does not affect the taking of another project.  Ex: If you buy machine A, you can also buy machine B, or not.  Ex: Cash flows from Project A do not affect cash flows for Project B.  Projects that are Not Mutually Exclusive are said to be Independent. 49
50. 50. 50 NPV & IRR  NPV and IRR will generally give us the same decision if:  Conventional Cash Flows =  Cash flow time 0 is negative.  Remaining cash flows are positive.  Projects (investments) Are Independent:  The decision to accept/reject this project does not affect the decision to accept/reject any other project.  Independent = “not mutually exclusive”. OK to use IRR or NPV Both give same answer.
51. 51. 51 DO NOT Use IRR, Instead Use NPV  DO NOT use IRR for projects that have non-conventional cash flows  DO NOT use IRR for projects that are mutually exclusive. NOT OK to use IRR Use NPV instead
52. 52. 52 IRR and Nonconventional Cash Flows  When the cash flows change sign more than once, there is more than one IRR  When you solve for IRR you are solving for the root of an equation and when you cross the x-axis more than once, there will be more than one return that solves the equation  If you have more than one IRR, which one do you use to make your decision?
53. 53. Example8:Non-conventional CashFlows:YouWillGetTwo Answers.WhichIsCorrect? 53
54. 54. 54 Summary of Decision Rules  The NPV is positive at a required return of 15%, so you should Accept.  If you use Excel, you would get an IRR of 14% which would tell you to Reject.  You need to recognize that there are non-conventional cash flows and use NPV for decision rule.
55. 55. 55 IRR and Mutually Exclusive Projects  So far we have only asked the question: “Should we invest our \$ in Project A?”  But what if we ask: “Should we invest our \$ in Project A or B?”  Mutually exclusive projects  If you choose one, you can’t choose the other  Example: You can choose Investment A or B, but not both.
56. 56. 56 Example 9: Mutually Exclusive Projects The required return for both projects is 10%. Which project should you accept and why? Period Cash Flow A Cash Flow B 0 -5,500.0 -5,500.0 1 2,500.0 1,100.0 2 2,200.0 2,200.0 3 2,200.0 2,750.0 4 1,650.0 3,000.0
57. 57. Example 9: NPV and IRR Can Give Different Answers. For These Cash Flows, When RRR = 10%, We Get Different Answers. Total cash flows are larger, but payback more slowly, so higher NPV at low RRR Mutually Exclusive Projects (Investements) RRR 10% Period Cash Flow A Cash Flow B 0 -5,500.0 -5,500.0 1 2,500.0 1,100.0 2 2,200.0 2,200.0 3 2,200.0 2,750.0 4 1,650.0 3,000.0 IRR 0.2183 0.1986 NPV 1,370.8 1,433.3 At RRR = 10%, we use NPV as criteria and accept B. 57
58. 58. Example 9: NPV and IRR NPV Profile shows that NPV depends on RRR. IRR is the same no matter what the RRR is. Bigger cash flows in early years means they are less affected by large RRR (cash flows closer to time zero are less affected by discounting (less time to compound)) Payback is quicker, so higher NPV at high RRR. Mutually Exclusive Projects (Investements) RRR 17% Period Cash Flow A Cash Flow B 0 -5,500.0 -5,500.0 1 2,500.0 1,100.0 2 2,200.0 2,200.0 3 2,200.0 2,750.0 4 1,650.0 3,000.0 IRR 0.2183 0.1986 NPV 498.0 365.3 At RRR = 17%, we use NPV as criteria and accept A. 58
59. 59. NPV B > NPV A, When Discount Rate < 12% Ranking conflict: IRR & NPV give different answers NPV A > NPV B, When Discount Rate > 12% No ranking conflict: IRR and NPV give same answer Example 9: NPV Profile shows that NPV depends on RRR. ME – Don’t Use IRR, use NPV. NPV B NPV A 59
60. 60. 60 Conflicts Between NPV and IRR  NPV directly measures the increase in value to the firm  Whenever there is a conflict between NPV and another decision rule, you should always use NPV  IRR is unreliable in the following situations  Non-conventional cash flows  Mutually exclusive projects
61. 61. Modified Internal Rate of Return (MIRR) Example 10: 61
62. 62. Modified Internal Rate of Return (MIRR)  3 different methods  Controversial:  Not one way to calculate MIRR (different results that with large values and long time frames can lead to large differences).  Is it really a rate if it comes from modified cash flows?  Why not just use NPV?  If you use a discount rate to get modified cash flows, you can not get a true IRR.  Cash reinvested may be unrealistic because, who knows if the rate that you are using for discounting is the same rate that would be applied to a cash flow that might be used for any number of things. 62
63. 63. 63 Profitability Index (Benefit Cost Ratio)  PI Formula= PVFCF/Initial Cost  PI > 1, accept project  PI < 1, reject project  Measures the benefit per unit cost, based on the time value of money  A profitability index of 1.1 implies that for every \$1 of investment, we create an additional \$0.10 in value  Use this PI Formula = PVFCF/Initial Cost – 1  This measure can be very useful in situations where we have limited capital (can’t do all projects, then select greater PI)
64. 64. PI Example 11:
65. 65. 65 Advantages and Disadvantages of Profitability Index  Advantages  Closely related to NPV, generally leading to identical decisions  Easy to understand and communicate  May be useful when available investment funds are limited  Disadvantages  May lead to incorrect decisions in comparisons of mutually exclusive investments  Scale is not revealed  10/5 = 1000/500
66. 66. 66 Capital Budgeting In Practice  We should consider several investment criteria when making decisions  NPV and IRR are the most commonly used primary investment criteria  Payback is a commonly used secondary investment criteria  Why so many? Because they are all only estimates!  The financial manager acts in the stockholder’s best interest by identifying and taking positive NPV projects
67. 67. 67
68. 68. 68 Quick Quiz  Consider an investment that costs \$150,000 and has a cash inflow of \$38,500 every year for 6 years and in 7th year the cash flow is \$2,000. The required return is 15% and required payback is 3 years.  What is the payback period?  What is the NPV?  What is the IRR?  Should we accept the project?  What decision rule should be the primary decision method?  When is the IRR rule unreliable?

70. 70. Multiple IRRs  Descartes Rule of Signs  Polynomial of degree n→n roots  When you solve for IRR you are solving for the root of an equation  One positive ?? real root per sign change  Remaining are imaginary (i2 = -1) 0 )IRR1( CFn 0t t t = + ∑=
71. 71. Two Reasons NPV Profiles Cross  Size (scale) differences.  Smaller project frees up funds sooner for investment.  The higher the opportunity cost, the more valuable these funds, so high discount rate favors small projects.  Timing differences.  Project with faster payback provides more CF in early years for reinvestment.  If discount rate is high, early CF especially good
72. 72. Reinvestment Rate Assumption  IRR assumes reinvestment at IRR  NPV assumes reinvestment at the firm’s weighted average cost of capital (opportunity cost of capital)  More realistic  NPV method is best  NPV should be used to choose between mutually exclusive projects
