Title: Unit 4
1Unit 4 Capital Budgeting Decision Methods
- This last unit ties together everything we have
covered in the first three units the time value
of money, risk and return, and cash flow
forecasting by covering methods firms can use
to determine if long-term investment alternatives
should be accepted or rejected - The goal is to utilize decision techniques that
lead to profitable investment decisions and
increase firm value
2Three criteria we will apply for comparing
different Capital Budgeting Decision Methods
- A good method should incorporate the time value
of money - A good method should incorporate all the relevant
cash flows of the investment - A good method should provide unambiguous
decisions on whether to invest or reject
investment proposals
3Decision Methods
- Payback Period
- Net Present Value (NPV)
- Internal Rate of Return (IRR)
4Method 1 Payback Period
- The payback period answers the question How long
will it take to recover the initial cost of this
investment? - The method involves summing the annual cash flows
until the sum is greater than or equal to the
initial project investment - The payback decision rule is If the project
payback is less than or equal to our firms
required payback period, accept. Otherwise,
reject.

6Evaluating the Payback Period Method
- First, realize this method gives you a measure of
project time, or liquidity it does not provide
any insight into the profitability of the
investment - It does not incorporate the time value of money
into the analysis - It does not consider all of the project cash
flows note that the cash flow from year 5 was
note included in the payback analysis - Finally, is this a good investment proposal? It
depends on the firms internal payback
requirement if it is 2 years, this proposal
would be rejected, but if it is 4 years, this is
an acceptable investment. Realize the payback
rule is therefore subjective and arbitrary
7Method 2 - The Net Present Value Method
- The NPV method answers the question How much
will this investment increase the firms value
today? - The method involves finding the present value of
the future cash flow stream, and subtracting the
initial investment - The NPV rule is if the projects NPV gt 0 then
accept, NPV lt 0 then reject
8An example of the Net Present Value method
assume the firms cost of capital, or hurdle
rate, is 10
9Evaluating the NPV method
- Since the example NPV is positive, the decision
is to invest in the project - NPV is a measure of project profitability it
indicates how much the project adds to the firms
value in present value money - NPV considers the time value of money through the
discounting process - NPV considers all of the projects cash flows,
since all are discounted and summed - The NPV decision rule is clear positive NPV
projects increase firm value, while negative NPV
projects decrease firm value
10Method 3 The Internal Rate of Return Method
- The IRR method answers the question What is the
expected rate of return on this investment? - IRR is the unique discount rate that makes the
present value of the future cash flow stream
equal to the initial project cost - IRR decision rule if IRR gt firms cost of
capital (required rate of return) then invest if
IRR lt cost of capital do not invest
11An example of the Internal Rate of Return Method
12Evaluating the IRR Method
- The IRR function is a built in financial function
in Microsoft Excel, as well as in financial
calculators - Since the IRR gt 10 in this example, the decision
is to invest - The IRR method considers the time value of money,
since it is the discount rate used in the
analysis - The IRR does consider all of the cash flows
forecasted for the projects - For independent project proposals, IRR and NPV
will give consistent invest/reject decisions
13Comparing and Contrasting NPV and IRR capital
investment methods
- IRR is the geometric, or compound, expected
return on investment - IRR assumes all cash flows from the project are
reinvested at the IRR rate - While NPV is consistent with the goal of
maximizing firm value, many firms like to use IRR
because it is easier to communicate an expected
rate of return (a relative profitability measure)
rather than an absolute euro increase in firm
value
14Possible Conflicts between NPV and IRR
- If a firm is considering mutually exclusive
project proposals, there are two situations where
IRR and NPV may give conflicting ranking
decisions - If one project is much larger than the other in
terms of required investment, IRR and NPV may
conflict on which is more profitable for the firm - Also, if the timing of when the cash flows occur
is dramatically different between the two
projects, IRR and NPV may give conflicting
rankings
15An example of conflicting rankings due to
differences in the timing of the respective cash
flow streams
16Comments on previous example
- Note that, while Project K has a steady cash flow
stream throughout the life of the project,
Project L generates the larger cash flows in its
early years - Because IRR assumes reinvestment of cash flows,
the larger cash flows early results in Project L
having the higher IRR - However, Project K has the higher NPV
- In the case of conflicts for mutually exclusive
choices, NPV provides the most theoretically
sound decision method, since it indicates the
investment choice that provides the largest
increase in firm value
17Comparing Investments of Different Size the
Profitability Index
- For two investments of different size (required
amounts of investment), the NPV method can be
altered to provide a relative ranking index - The Profitability Index is the ratio of the
present value of the future cash flows divided by
the project cost - The result is the present euro benefit per euro
of required investment
18An Example of Profitability Index
19Notes on Profitability Index example
- First,these two proposed projects have different
sizes, with Project D having a much higher
required investment cost - By taking the ratio of the present value of the
future cash flows to the cost, we see that
Project D is expected to provide 1.18 euros per
each euro invested, compared to 1.16 euros per
euro invested for Project E. - The decision rule for PI is the gt the PI, the
better
