5-1

Learning Objectives
• Understand different steps of the capital-expenditure
process.
• Different methods of project evaluation and decision
rules.
• Outline the advantages and disadvantages of the main
project evaluation methods.
• Explain why the NPV method is preferred to all other
methods.
• Understand the link between economic value added (EVA)
and net present value (NPV).
• Know the relationship between options, managerial
flexibility and firm value analysis during project evaluation.


5-2

Capital Expenditure Process
• The capital expenditure process involves:
– Generation of investment proposals.
– Evaluation and selection of those proposals.
– Approval and control of capital expenditures.
– Post-completion audit of investment projects.


5-3

Generation of Investment
Proposals
• Investment ideas can range from simple
upgrades of equipment, replacing existing
inefficient equipment, through to plant
expansions, new product development or
corporate takeovers.
• Generation of good ideas for capital expenditure
is better facilitated if a systematic means of
searching for and developing them exists.
• This may be assisted by financial incentives
and bonuses for those who propose successful
projects.
5-4

Evaluation and Selection of
Investment Proposals
• In order to evaluate a proposal, the following data
should be considered:
– Brief description of the proposal.
– Statement as to why it is desirable or necessary.
– Estimate of the amount and timing of the cash outlays.
– Estimate of the amount and timing of the cash inflows.
– Estimate of when the proposal will come into operation.
– Estimate of the proposal’s economic life.


5-5

Approval and Control of Capital
Expenditures
• Capital-expenditure budget (CEB) maps out the
estimated future capital expenditure on new and
continuing projects.
• CEB has the important role of setting administrative
procedures to implement the project (project
timetable, procedures for controlling costs).
• Timing is important because project delays and
cost over-runs will lower the NPV of a project,
costing shareholder wealth.

5-6

Post-completion Audit of
Investment Projects
• Highlights any cash flows that have deviated
significantly from the budget and provides
explanations where possible.
• Benefits of conducting an audit:
– May improve quality of investment decisions.
– Provides information that will enable
implementation of improvements in the project’s
operating performance.
– May result in the re-evaluation and possible
abandonment of an unsuccessful project.


5-7

Methods of Project Evaluation
• Different methods of project evaluation include:
– Net present value (NPV).
– Internal rate of return (IRR).
– Benefit-cost ratio (profitability index).
– Payback period (PP).
– Accounting rate of return (ARR).

5-9

Discounted Cash Flow Methods
• Discounted cash flow (DCF) methods involve
the process of discounting a series of future net
cash flows to their present values.
• DCF methods include:
– The net present value method (NPV).
– The internal rate of return method (IRR).


5-10

Net Present Value (NPV)
• Difference between the PV of the net cash flows
(NCF) from an investment, discounted at the required
rate of return, and the initial investment outlay.
• Measuring a project’s net cash flows:
– Forecast expected net profit from project.
– Estimate net cash flows directly.

• The standard NPV formula is given by:
n

NPV =

Ct

∑ (1 + k )
t =1

t

− C0

where:
C0 = initial cash outlay on project
Ct = net cash flow generated by project at time t
n = life of the project
k = required rate of return


5-11

Net Cash Flow
• Cash inflows:
– Receipts from sale of goods and services.
– Receipts from sale of physical assets.

• Cash outflows:
– Expenditure on materials, labour and
indirect expenses for manufacturing.
– Selling and administrative.
– Inventory and taxes.


5-12

Evaluation of NPV
• NPV method is consistent with the company’s
objective of maximising shareholders’ wealth.
– A project with a positive NPV will leave the company
better off than before the project and, other things
being equal, the market value of the company’s shares
should increase.

• Decision rule for NPV method:
– Accept a project if its NPV is positive when the
project’s NCFs are discounted at the required rate of
return.


5-13

NPV Example
• Example 5.1:
– Investment of $9000.
– Net cash flows of $5090, $4500 and $4000 at
the end of years 1, 2 and 3 respectively.
– Assume required rate of return is 10% p.a.
– What is the NPV of the project?


5-14

NPV Example (cont.)
Solution:
•

Apply the NPV formula given by Equation 5.5.
n

3
(1.10 ) (1.10 ) (1.10 )

= 4627 + 3719 + 3005 − 9000
= 2351
•

Thus, using a discount rate of 10%, the project’s
NPV = +$2351 > 0, and is therefore acceptable.


5-15

Internal Rate of Return (IRR)
• The internal rate of return (IRR) is the
discount rate that equates the PV of a project’s
net cash flows with its initial cash outlay.
– IRR is the discount rate (or rate of return) at which
the net present value is zero.

• The IRR is compared to the required rate of
return (k).
• If IRR > k, the project should be accepted.


5-16

Calculation of Internal Rate of
Return
• By setting the NPV formula to zero and treating the
rate of return as the unknown, the IRR is given by:
n
Ct
− C0 = 0
t
t =1 1 + k
where:

∑(

)

C0 = initial cash outlay on project
n = life of the project
r = internal rate of return

5-17

Calculation of Internal Rate of
Return (cont.)
• Using the cash flows of Example 5.1, the IRR is:

5090
4500
4000

1 + ΙΡΡ (1 + ΙΡΡ ) (1 + ΙΡΡ )
ΙΡΡ = 25%


5-18

Multiple and Indeterminate
Internal Rates of Return
• Conventional projects have a unique rate of
return.
• Multiple or no internal rates of return can occur for
non-conventional projects with more than one
sign change in the project’s series of cash flows.
• Thus, care must be taken when using the IRR
evaluation technique.
• Under IRR: Accept the project if it has a unique
IRR > the required rate of return.

5-19

Choosing Between the
Discounted Cash Flow Methods
• Independent investments:
– Projects that can be considered and evaluated in
isolation from other projects.
– This means that the decision on one project will not
affect the outcomes of another project.

• Mutually exclusive investments:
– Alternative investment projects, only one of which can be
accepted.
– For example, a piece of land is used to build a factory,
which rules out an alternative project of building a
warehouse on the same land.


5-20

Choosing Between the Discounted
Cash Flow Methods (cont.)
• Independent investments:
– For independent investments, both the IRR and
NPV methods lead to the same accept/reject
decision, except for those investments where the
cash flow patterns result in either multiple or no
internal rate(s) of return.
– In such cases, it doesn’t matter whether we use
NPV or IRR.


5-21

Choosing Between the Discounted
Cash Flow Methods (cont.)
• Evaluating mutually exclusive projects:
– NPV and IRR methods can provide a different
ranking order.
– The NPV method is the superior method for mutually
exclusive projects.
– Ranking should be based on the magnitude of NPV.


5-22

Benefit-Cost Ratio (Profitability
Index)
• The profitability index is calculated by dividing
the present value of the future net cash flows by
the initial cash outlay:

PV of net cash flows
Benefit Cost Ratio =
Initial cash outlay
• Decision rule:
– Accept if benefit–cost ratio > 1
– Reject if benefit–cost ratio < 1


5-23

Other Methods of Project
Evaluation
• Two major non-discounted cash flow
methods that are used:
– Accounting rate of return method (ARR)
– Payback period method (PP)

• These methods are usually employed in
conjunction with the discounted cash flow
methods of project evaluation.


5-24

• Earnings (after depreciation and tax) from a
project expressed as a percentage of the
investment outlay.
• The calculation involves:
– Estimating the average annual earnings to be
generated by the project.
– Investment outlay (initial or average).


5-25

(cont.)
• Fundamental problems of ARR in project
valuation:
– Arbitrary measure — based on accounting profit as
opposed to cash flows, depends on some accounting
decisions such as treatment of inventory and
depreciation.
– Ignores timing of the earnings stream — no time
value of money concepts are applied, as equal
weight is given to accounting profits in each year of
the project’s life.


5-26

Payback Period
•

The time it takes for the initial cash outlay on a project to be
recovered from the project’s after-tax net cash flows.

•

Using Example 5.1, assume cash flow occurs throughout year
and find the payback period of the project:
Project cost: –9000
Year 1:

+5090
3910

Year 2: 3910/4500 = 0.87, so it takes 1.87 years
for the project to recover its initial cost.
•

Decision:
– Compare payback to some maximum acceptable payback period.
– What length of time represents the ‘correct’ payback period as a
standard against which to measure the acceptability of a particular
project?


5-27

Payback Period (cont.)
• Strengths:
– It is a simple method to apply.
– It identifies how long funds are committed to a project.

• Weaknesses:
– Inferior to discounted cash flow techniques because it
fails to account for the magnitude and timing of all the
project’s cash flows.
– Does not consider how profitable a project will be, just
how quickly outlay will be recovered.


5-28

Summary of Evaluation Methods
• Discounted cash flow methods are superior
investment appraisal methods as they account for
timing of cash flows and the time value of money.
• DCF methods will always give the same
accept/reject decision for a conventional project.
• In practice, the above-mentioned alternative
project evaluation methods (most likely payback
period) may be used in conjunction with DCF
methods: see Table 5.1.


5-29

Economic Value Added (EVA)
• Alternative to discounted cash flow methods,
accounting rate of return and payback period.
• Key factor is the required rate of return.
• EVA is the difference between the project’s
accounting profit and the required return on
the capital invested in the project.
• EVA can be improved by increasing accounting
profit or by reducing capital employed.


5-30

Economic Value Added (cont.)
• EVA is given by:

EVAt = Ct +

(I t

− I t −1 ) − kI t −1

where:
I t = investment value, end of year t
I t −1 = investment value, end of year t -1
k = required rate of return
• Discounted sum of EVAs equals NPV of project.

5-31

Real Option Analysis
• In practice, company management will often have time
flexibility in their investment decision choices and ways to
manage project if firm decides to proceed.
• Management choices are often known as real options.
• Option gives a successful tender for a project the right but
not the obligation to initiate operation on a project.
• Depending on changes in circumstances successful bidder
may or may not take up option immediately. Hence, option
gives bidder the right to exploit any advantageous changes
in circumstances.
• It is significant to consider value associated with
management’s flexibility. (pp.127–8)


5-32

Summary
• NPV method is recommended for project
evaluation. The method is consistent with
shareholder wealth maximisation.
• NPV is also simple to use and gives rise to
fewer problems than the IRR method, such
as non-uniqueness.
• Independent projects — accept if NPV > 0,
reject if NPV < 0.


5-33

Summary (cont.)
• Mutually exclusive projects — accept project with the
highest NPV.
• In practice, other valuation methods such as accounting
rate of return, payback period and economic value
added are used in conjunction with NPV, despite a
preference for DCF methods.
• This may be to measure some other effect, such as the
effect of the project on liquidity — payback period.
• Real option analysis considers managerial flexibility is
valuable unlike project evaluation methods, where the
idea of management ability to intervene in an ongoing
project is ignored.
