The relationship between the NPV and IRR methodsFigure 8.4 If the discount rate were zero, the NPV would be the sum of the net cash flows.. Thus, in practice it is not usually necessary
Trang 1In increasing the discount rate from 20 per cent to 30 per cent, we have reduced theNPV from £24,190 (positive) to £1,880 (negative) Since the IRR is the discount ratethat will give us an NPV of exactly zero, we can conclude that the IRR of BillingsgateBattery Company’s machine project is very slightly below 30 per cent Further trialscould lead us to the exact rate, but there is probably not much point, given the likelyinaccuracy of the cash flow estimates It is probably good enough, for practical pur-poses, to say that the IRR is about 30 per cent.
The relationship between the NPV method discussed earlier and the IRR is showngraphically in Figure 8.4 using the information relating to the Billingsgate BatteryCompany
The relationship between the NPV and IRR methodsFigure 8.4
If the discount rate were zero, the NPV would be the sum of the net cash flows In other words,
no account would be taken of the time value of money However, if we assume increasing count rates, there is a corresponding decrease in the NPV of the project When the NPV line crosses the horizontal axis there will be a zero NPV, and the point where it crosses is the IRR.

You should use the discount table on pp 521–522 (Hint: Remember that you already
know the NPV of this project at 15 per cent (from Activity 8.12).)
Since we know that, at a 15 per cent discount rate, the NPV is a relatively large negativefigure, our next trial is using a lower discount rate, say 10 per cent:
Activity 8.15
Trang 2We could undertake further trials in order to derive the precise IRR If, however, wehave to calculate the IRR manually, further iterations can be time-consuming.
We can get an acceptable approximation to the answer fairly quickly by first lating the change in NPV arising from a 1 per cent change in the discount rate Thiscan be done by taking the difference between the two trials (that is, 15 per cent and
calcu-10 per cent) that we have already carried out (in Activities 8.12 and 8.15):
Trial Discount factor Net present value
In practice, most businesses have computer software packages that will derive a project’s IRR very quickly Thus, in practice it is not usually necessary either to make aseries of trial discount rates or to make the approximation that we have just considered.Users of the IRR method should apply the following decision rules:
INTERNAL RATE OF RETURN (IRR) 281
Time Cash flows Discount factor Present value

is often referred to as the hurdle rate and, logically, this should be the opportunity
cost of finance
l Where there are competing projects (that is, the business can choose only one oftwo or more viable projects), the one with the higher (or highest) IRR should beselected
IRR has certain attributes in common with NPV All cash flows are taken intoaccount, and their timing is logically handled

Trang 4Problems with IRR
The main disadvantage of IRR, relative to NPV, is the fact that it does not directlyaddress the question of wealth generation It could therefore lead to the wrong deci-sion being made This is because IRR will always rank a project with an IRR of 25 percent above one with an IRR of 20 per cent, assuming an opportunity cost of finance
of, say, 15 per cent Although accepting the project with the higher percentage returnwill often generate more wealth, this may not always be the case This is because IRR
completely ignores the scale of investment.
With a 15 per cent cost of finance, £15 million invested at 20 per cent for one year will make us wealthier by £0.75 million (that is, 15 × (20 − 15)% = 0.75) With thesame cost of finance, £5 million invested at 25 per cent for one year will make us only
£0.5 million (that is, 5 × (25 − 15)% = 0.50) IRR does not recognise this It should
be acknowledged that it is not usual for projects to be competing where there is such
a large difference in scale Even though the problem may be rare and so, typically, IRR will give the same signal as NPV, a method that is always reliable (NPV) must bebetter to use than IRR This problem with percentages is another example of the oneillustrated by the Mexican road discussed in Real World 8.3
A further problem with the IRR method is that it has difficulty handling projectswith unconventional cash flows In the examples studied so far, each project has a negative cash flow arising at the start of its life and then positive cash flows thereafter.However, in some cases, a project may have both positive and negative cash flows
at future points in its life Such a pattern of cash flows can result in there being morethan one IRR, or even no IRR at all This would make the IRR method difficult to use,although it should be said that this is quite rare in practice This is never a problem forNPV, however
When undertaking an investment appraisal, there are several practical points that weshould bear in mind:
l Past costs As with all decisions, we should take account only of relevant costs in our analysis This means that only costs that vary with the decision should be con-sidered Thus, all past costs should be ignored as they cannot vary with the decision
In some cases, a business may incur costs (such as development costs and market
research costs) before the evaluation of an opportunity to launch a new product
As those costs have already been incurred, they should be disregarded, even thoughthe amounts may be substantial Costs that have already been committed but notyet paid should also be disregarded Where a business has entered into a bindingcontract to incur a particular cost, it becomes in effect a past cost even though payment may not be due until some point in the future
l Common future costs It is not only past costs that do not vary with the decision; some
future costs may also be the same For example, the cost of raw materials may notvary with the decision whether to invest in a new piece of manufacturing plant or
to continue to use existing plant
l Opportunity costs Opportunity costs arising from benefits forgone must be taken into
account Thus, for example, when considering a decision concerning whether or not

‘
Trang 5to continue to use a machine already owned by the business, the realisable value ofthe machine might be an important opportunity cost.
l Taxation Owners will be interested in the after-tax returns generated from the
busi-ness, and so taxation will usually be an important consideration when making aninvestment decision The profits from the project will be taxed, the capital invest-ment may attract tax relief and so on Tax is levied at significant rates This meansthat, in real life, unless tax is formally taken into account, the wrong decision couldeasily be made The timing of the tax outflow should also be taken into accountwhen preparing the cash flows for the project
l Cash flows not profit flows We have seen that for the NPV, IRR and PP methods, it
is cash flows rather than profit flows that are relevant to the assessment of ment projects In an investment appraisal requiring the application of any of thesemethods we may be given details of the profits for the investment period Theseneed to be adjusted in order to derive the cash flows We should remember that the
invest-operating profit before non-cash items (such as depreciation) is an approximation to
the cash flows for the period, and so we should work back to this figure
When the data are expressed in profit rather than cash flow terms, an adjustment
in respect of working capital may also be necessary Some adjustment should bemade to take account of changes in working capital For example, launching a newproduct may give rise to an increase in the net investment made in trade receivablesand inventories less trade payables, requiring an immediate outlay of cash This outlay for additional working capital should be shown in the NPV calculations aspart of the initial cost However, at the end of the life of the project, the additionalworking capital will be released This divestment results in an effective inflow of cash
at the end of the project; it should also be taken into account at the point at which
it is received
l Year-end assumption In the examples and activities that we have considered so far
in this chapter, we have assumed that cash flows arise at the end of the relevant year This is a simplifying assumption that is used to make the calculations easier.(However, it is perfectly possible to deal more precisely with the cash flows.) As
we saw earlier, this assumption is clearly unrealistic, as money will have to be paid
to employees on a weekly or monthly basis and credit customers will pay within
a month or two of buying the product or service Nevertheless, it is probably not aserious distortion We should be clear, however, that there is nothing about any ofthe four appraisal methods that demands that this assumption be made
l Interest payments When using discounted cash flow techniques (NPV and IRR),
inter-est payments should not be taken into account in deriving the cash flows for theperiod The discount factor already takes account of the costs of financing, and so
to take account of interest charges in deriving cash flows for the period would bedouble counting
l Other factors Investment decision making must not be viewed as simply a
mechan-ical exercise The results derived from a particular investment appraisal method will be only one input to the decision-making process There may be broader issuesconnected to the decision that have to be taken into account but which may bedifficult or impossible to quantify
The reliability of the forecasts and the validity of the assumptions used in theevaluation will also have a bearing on the final decision

The factory is leased, and there are still four years of the lease remaining The tors are uncertain whether the factory should be closed immediately or at the end of the period of the lease Another business has offered to sub-lease the premises from Manuff at a rental of £40,000 a year for the remainder of the lease period.

of financial position (balance sheet) value of £400,000 In the event of immediate closure, the machinery and equipment could be sold for £220,000 The working capital at the factory is £420,000, and could be liquidated for that amount immediately, if required.
Alternatively, the working capital can be liquidated in full at the end of the lease period.
Immediate closure would result in redundancy payments to employees of £180,000.
If the factory continues in operation until the end of the lease period, the following operating profits (losses) are expected:
Year 1 Year 2 Year 3 Year 4

Operating profit/(loss) 160 (40) 30 20
The above figures include a charge of £90,000 a year for depreciation of machinery and equipment The residual value of the machinery and equipment at the end of the lease period is estimated at £40,000.

l The continued popularity of PP, and to a lesser extent ARR, despite their theoreticalshortcomings
Investment appraisal in practice
Notes:
1 Each year’s operating cash flows are calculated by adding back the depreciationcharge for the year to the operating profit for the year In the case of the operatingloss, the depreciation charge is deducted
2 In the event of closure, machinery could be sold immediately Thus an opportunitycost of £220,000 is incurred if operations continue
3 If operations are continued, there will be a saving in immediate redundancy costs
of £180,000 However, redundancy costs of £150,000 will be paid in four years’ time
4 If operations are continued, the opportunity to sub-lease the factory will be forgone
5 Immediate closure would mean that working capital could be liquidated If operationscontinue, this opportunity is foregone However, working capital can be liquidated
in four years’ time
(b) Discount rate 12 per cent 1.000 0.893 0.797 0.712 0.636
(c) Other factors that may influence the decision include:
l The overall strategy of the business The business may need to set the decision
within a broader context It may be necessary to manufacture the products at the factory because they are an integral part of the business’s product range Thebusiness may wish to avoid redundancies in an area of high unemployment for aslong as possible
l Flexibility A decision to close the factory is probably irreversible If the factory
continues, however, there may be a chance that the prospects for the factory willbrighten in the future
l Creditworthiness of sub-lessee The business should investigate the
creditworthi-ness of the sub-lessee Failure to receive the expected sub-lease payments wouldmake the closure option far less attractive
l Accuracy of forecasts The forecasts made by the business should be examined
carefully Inaccuracies in the forecasts or any underlying assumptions may changethe expected outcomes
(d) The NPV of the decision to continue operations rather than close immediately is positive Hence, shareholders would be better off if the directors took this course ofaction The factory should therefore continue in operation rather than close down Thisdecision is likely to be welcomed by employees and would allow the business to main-tain its flexibility

l It gives emphasis to the early cash flows when there is greater certainty concerning theaccuracy of their predicted value

Trang 13Assessing the level of risk
Sensitivity analysis
One popular way of attempting to assess the level of risk is to carry out a sensitivity analysis on the proposed project This involves an examination of the key input values affecting the project to see how changes in each input might influence the viability of the project
First, the investment is appraised, using the best estimates for each of the input factors (for example, labour cost, material cost, discount rate and so on) Assuming thatthe NPV is positive, each input value is then examined to see how far the estimatedfigure could be changed before the project becomes unviable for that reason alone Let
us suppose that the NPV for an investment in a machine to provide a particular service
is a positive value If we were to carry out a sensitivity analysis on this project, weshould consider in turn each of the key input factors:
l initial outlay for the machine;
l sales volume and selling price;
l relevant operating costs;
l life of the project; and
l financing costs (to be used as the discount rate)
We should seek to find the value that each of them could have before the NPV figurewould become negative (that is, the value for the factor at which NPV would be zero).The difference between the value for that factor at which the NPV would equal zeroand the estimated value represents the margin of safety for that particular input Theprocess is set out in Figure 8.6
A computer spreadsheet model of the project can be extremely valuable for this cise because it then becomes a very simple matter to try various values for the inputdata and to see the effect of each As a result of carrying out a sensitivity analysis, the
Trang 14exer-decision maker is able to get a ‘feel’ for the project, which otherwise might not be sible Example 8.3, which illustrates a sensitivity analysis is, however, straightforwardand can be undertaken without recourse to a spreadsheet.

It will cost £500,000 and the six flats completed during this stage are expected to

of renovation will be the subject of a binding contract with local builders if theproperty is bought There is, however, some uncertainty over the remaining inputvalues The business estimates its cost of capital at 12 per cent a year
(a) What is the NPV of the proposed project?
(b) Assuming none of the other inputs deviates from the best estimates provided,(1) What auction price would have to be paid for the manor house to causethe project to have a zero NPV?
(2) What cost of capital would cause the project to have a zero NPV?
(3) What is the sale price of each of the flats that would cause the project to have
a zero NPV? (Each flat is projected to be sold for the same price: £150,000.)(c) Is the level of risk associated with the project high or low? Discuss your findings
Solution
(a) The NPV of the proposed project is as follows:
Cash flows Discount factor Present value
Year 1 (£900,000 − £500,000) 400,000 0.893 357,200Year 2 (£450,000 − £300,000) 150,000 0.797 119,550
(b) (1) To obtain a zero NPV, the auction price would have to be £26,750 higher
than the current estimate – that is, a total price of £476,750 This is about
6 per cent above the current estimated price
(2) As there is a positive NPV, the cost of capital that would cause the project
to have a zero NPV must be higher than 12 per cent Let us try 20 per cent
Cash flows Discount factor Present value
Year 1 (£900,000 − £500,000) 400,000 0.833 333,200Year 2 (£450,000 − £300,000) 150,000 0.694 104,100
Example 8.3
‘
Trang 15As the NPV using a 20 per cent discount rate is negative,the ‘break-even’ cost
of capital lies somewhere between 12 per cent and 20 per cent A reasonableapproximation is obtained as follows:
Discount rate Net present value
(6Y × 0.893) + (3Y × 0.797) = £26,750
Y = £3,452The sale price of each flat necessary to obtain a zero NPV is therefore
£150,000 − £3,452 = £146,548This represents a fall in the estimated price of 2.3 per cent
(c) These calculations indicate that the auction price would have to be about
6 per cent above the estimated price before a zero NPV is obtained The margin
of safety is, therefore, not very high for this factor In practice this should notrepresent a real risk because the business could withdraw from the bidding ifthe price rises to an unacceptable level
The other two factors represent serious risks, because only after the project
is at a very late stage can the business be sure as to what actual cost of capitaland price per flat will prevail The calculations reveal that the price of the flatswould only have to fall by 2.3 per cent from the estimated price before theNPV is reduced to zero Hence, the margin of safety for this factor is evensmaller However, the cost of capital is less sensitive to changes and therewould have to be an increase from 12 per cent to 17.4 per cent before the pro-ject produced a zero NPV It seems from the calculations that the sale price ofthe flats is the most sensitive factor to consider A careful re-examination ofthe market value of the flats seems appropriate before a final decision is made

Trang 16There are two major drawbacks with the use of sensitivity analysis:
l It does not give managers clear decision rules concerning acceptance or rejection ofthe project and so they must rely on their own judgement
l It is a static form of analysis Only one input is considered at a time, while the restare held constant In practice, however, it is likely that more than one input valuewill differ from the best estimates provided Even so, it would be possible to dealwith changes in various inputs simultaneously, were the project data put onto aspreadsheet model This approach, where more than one variable is altered at a time,
is known as scenario building
Real World 8.14 describes an evaluation of a mining project that incorporated sitivity analysis to test the robustness of the findings
IRR Pre-tax NPV Payback period
Sensitivity analysis was carried out on four key variables – the price of copper, the price
of gold, operating costs and capital outlay costs – to help assess the riskiness of the project This was done by assessing the IRR, NPV and PP, making various assumptionsregarding the prices of copper and gold and about the percentage change in both theoperating and the capital costs The following table sets out the findings
Average spot*
copper price US$/lb
Trang 17Expected net present value
Another means of assessing risk is through the use of statistical probabilities It may bepossible to identify a range of feasible values for each of the items of input data and toassign a probability of occurrence to each of these values Using this information, wecan derive an expected net present value (ENPV), which is, in effect, a weighted aver-age of the possible outcomes where the probabilities are used as weights To illustratethis method, let us consider Example 8.4
* The spot price is the price for immediate delivery of the mineral.
In its report, the business stated:
This project is most sensitive to percentage changes in the copper price which have the largest impact, whereas movements in the gold price have the least The impact of changes in operating costs is more significant than capital costs.

C Piperis (Properties) Ltd has the opportunity to acquire a lease on a block of flatsthat has only two years remaining before it expires The cost of the lease would
be £100,000 The occupancy rate of the block of flats is currently around 70 percent and the flats are let almost exclusively to naval personnel There is a largenaval base located nearby, and there is little other demand for the flats The occup-ancy rate of the flats will change in the remaining two years of the lease, depend-ing on the outcome of a defence review The navy is currently considering threeoptions for the naval base These are:
l Option 1 Increase the size of the base by closing down a base in another region
and transferring the personnel to the one located near the flats
l Option 2 Close down the naval base near to the flats and leave only a skeleton
staff there for maintenance purposes The personnel would be moved to a base
in another region
l Option 3 Leave the base open but reduce staffing levels by 20 per cent.
Example 8.4
Trang 18The expected NPV approach has the advantage of producing a single numerical come and of having a clear decision rule to apply If the expected NPV is positive, weshould invest; if it is negative, we should not.
out-However, the approach produces an average figure, and it may not be possible forthis figure actually to result This point was illustrated in Example 8.4 where theexpected annual cash flow (£61,200) does not correspond to any of the stated options.Perhaps more importantly, using an average figure can obscure the underlying riskassociated with the project Simply deriving the ENPV, as in Example 8.4, can be mis-leading Without some idea of the individual possible outcomes and their probability
DEALING WITH RISK 297
The directors of Piperis have estimated the following net cash flows for each ofthe two years under each option and the probability of their occurrence:
of the possible options will arise) The business has a cost of capital of 10 per cent
Should the business purchase the lease on the block of flats?
Solution
To calculate the expected NPV of the proposed investment, we must first late the weighted average of the expected outcomes for each year, using the prob-abilities as weights, by multiplying each cash flow by its probability of occurrence
calcu-Thus, the expected annual net cash flows will be:
Cash flows Probability Expected
Having derived the expected annual cash flows, we can now discount theseusing a rate of 10 per cent to reflect the cost of capital:
cash flows rate present value
We can see that the expected NPV is positive Hence, the wealth of shareholders
is expected to increase by purchasing the lease
Trang 19of occurring, the decision maker is in the dark In Example 8.4, were either of Options
2 or 3 to occur, the investment would be adverse (wealth-destroying) It is 40 per centprobable that one of these two options will occur, so this is a significant risk Onlyshould Option 1 arise (60 per cent probable) would investing in the flats represent agood decision Of course, in advance of making the investment, which option willactually occur is not known None of this should be taken to mean that the investment
in the flats should not be made, simply that the decision maker is better placed to make
a judgement where information on the possible outcomes is available Activity 8.18further illustrates this point
Qingdao Manufacturing Ltd is considering two competing projects Details are as follows:
l Project A has a 0.9 probability of producing a negative NPV of £200,000 and a 0.1 probability of producing a positive NPV of £3.8m.
l Project B has a 0.6 probability of producing a positive NPV of £100,000 and a 0.4 probability of producing a positive NPV of £350,000.
What is the expected net present value of each project?
The expected NPV of Project A is
[(0.1 × £3.8m) − (0.9 × £200,000)] = £200,000The expected NPV of Project B is
[(0.6 × £100,000) + (0.4 × £350,000)] = £200,000
Activity 8.18
Although the expected NPV of each project in Activity 8.18 is identical, this does notmean that the business will be indifferent about which project to undertake We cansee from the information provided that Project A has a high probability of making
a loss whereas Project B is not expected to make a loss under either possible outcome
If we assume that the shareholders dislike risk – which is usually the case – they willprefer the directors to take on Project B as this provides the same level of expectedreturn as Project A but for a lower level of risk
It can be argued that the problem identified above may not be significant where thebusiness is engaged in several similar projects This is because a worse than expectedoutcome on one project may well be balanced by a better than expected outcome
on another project However, in practice, investment projects may be unique eventsand this argument will not then apply Also, where the project is large in relation toother projects undertaken, the argument loses its force There is also the problem that
a factor that might cause one project to have an adverse outcome could also haveadverse effects on other projects For example, a large, unexpected increase in the price
of oil may have a simultaneous adverse effect on all of the investment projects of a particular business
Where the expected NPV approach is being used, it is probably a good idea to makeknown to managers the different possible outcomes and the probability attached to
each outcome By so doing, the managers will be able to gain an insight to the downside risk attached to the project The information relating to each outcome can be presented
