2Making Investment Decisions
- We have stated that we want the firm to take all
projects that generate positive NPV and reject
all projects that have a negative NPV. Capital
budgeting complications arise when you cannot,
either physically or financially undertake all
positive NPV projects. Then we have to devise
methods of choosing between alternative positive
NPV projects.
3Mutually Exclusive Projects
- IF, AMONG A NUMBER OF PROJECTS, THE FIRM CAN ONLY
CHOOSE ONE, THEN THE PROJECTS ARE SAID TO BE
MUTUALLY EXCLUSIVE. - For example Suppose you have the choice of
modifying an existing machine, or replacing it
with a brand new one. You could not do both and
produce the desired amount of output. Thus,
these projects are mutually exclusive. Given the
cash flows below, which of these projects do you
choose?

7EXAMPLES OF CAPITAL BUDGETING COMPLICATIONS
- 1. Optimal Timing
- 2. Long versus Short Life
- 3. Replacement Problem
- 4. Excess Capacity
- 5. Peak Load Problem (Fluctuating Load)
- 6. Capital Constraints
8EXAMPLES OF CAPITAL BUDGETING COMPLICATIONS
- These Capital Budgeting Complications will stop
the Firm from taking all possible positive NPV
PROJECTS. Thus, the firm is faced with the
choice of two possibilities. - Remember Goal is still Max NPV of all
possibilities
9EXAMPLES OF CAPITAL BUDGETING COMPLICATIONS
- We can divide these problems into three separate
classes, each with their own method of solutions.
- (1) Once and for all deal.
- Choose the one alternative having the
highest NPV. - (2) Repetitive Deal.
- Choose the one alternative having the
highest equivalent annual cash flow. - (3) Capital Budgeting Constraint
- Choose the combination of projects
having the highest NET PRESENT VALUE.
10Once and For all Deals
- INVESTMENT TIMING
- When is the optimal time to take on an
investment project? Consider T possible times,
where, - t 1, ...T.
- Then each "starting time" can be considered a
different project in a set of T mutually
exclusive projects. Then find that t which Max - NPV(t)
- (1r)t
11Once and For all Deals
- Example You are in the highly competitive area
of producing laundry soap and detergents. You
have a new product which you feel does a superior
job in washing clothes, but you anticipate that
the product will have difficulty being accepted
by the consumer. Thus you expect that if you
introduce the product now, you will have to
suffer a few years of losses until the product is
accepted by the consumer. A competitor is about
to come out with a similar product. You feel
that if you allow your competitor to come out
with the product first, you can benefit from the
time he spends acclimating your potential
customers. However, you will then be giving up
your competitive edge.
12Once and For all Deals
- The initial investment in the product has already
been spent, is a sunk cost and can be ignored for
this problem. The anticipated life of the
productive process is ten years from the time the
product is first produced. Thereafter, there
will be so much competition that any new
investment in this product will have a zero NPV.
The discount rate is 15.
13Once and For all Deals

14Once and For all Deals
- NPV(0) (Introduced Immediately) is 47.649
million - NPV(1) (Introduced in one year's time) is
55.531 million - NPV(2) (Introduced in two year's time) is
56.118 million -

- 47.649 55.531 56.118

- Calculate NPV from time 0.
15Once and For all Deals
- Shortcut
- Calculate the annualized rate of change of
NPV. If delaying causes the NPV to increase by
more than the discount rate, the project should
be delayed. If not, the project should not be
delayed.
16Once and For all Deals
- Caution
- This method assumes that the project cannot
be reproduced at a positive NPV after the initial
life of the project. Otherwise, you have to also
account for the fact that the project that is
started earlier can also be reproduced earlier.
In that case, the alternatives look like -
- START IMMEDIATELY
- 0 10 20

19Alternatives with Different Lives
- Example YOU HAVE THE OPTION OF UNDERTAKING ONE
OF TWO DIFFERENT WAYS OF ACHIEVING SOME GOAL.
WHICH ONE SHOULD YOU TAKE? - (A) A Bridge costing 5M lasts 15 years
- (B) A Bridge costing 4M lasts 10 years
- Both generate 1 Million in net revenues per
year. - Let the Discount rate 12 for each
alternative. - NPV (A) 1.81 Million
- NPV (B) 1.65 Million
20 Alternatives with Different Lives
- Conceptually
- The NPV rule would say, take the project with the
highest Net Present Value. This may be wrong. - Consider what happens after ten years.
- In particular by year 30.

22Alternatives with Different Lives
- ALTERNATIVE
- EQUIVALENT ANNUAL CASH FLOW
- (EACF) or (NUS in Hewlett Packard)
- Note BMA talk about Equivalent Annual Cost, this
is a more general concept. - Consider the annuity having the same NPV and life
of the project. - EACF (A) That annuity having a Present
Value of 1.81, lasting 15 years at a discount
rate of 12. - (A) PV(A) Annuity x PVFA(r, T)
-
- Annuity(A) 265,700 EACF(A)
- Annuity(B) 292,000 EACF(B)
23Alternatives with Different Lives
- This "Equivalent Annual Cash Flow" (or Cost) is a
convenient way of examining the host of
complicated, mutually exclusive capital budgeting
problems listed above These all involve -
- A TIMING PROBLEM
- (1) When to start project
- (2) When to "cash in"
- Forestry
- Wine
- (3) Replacement
- (4) Short vs. Long lived Project
- (5) When and how to increase capacity
- Can all be dealt with in a similar way?
24Mutually exclusive projects with different
Starting Times
- Instead of assuming that this is a once and for
all deal, assume that the alternatives can be
reproduced indefinitely. Note that this case
differs from the Laundry Detergent Example
treated above - 1. How?
- 2. What impact will this have on the timing
decision?
25Mutually exclusive projects with different
Starting Times
- Consider an example The mutually exclusive
decision, - when to cut down a forest
- In ten years with NCF of
47,000 - In eleven years with NCF of 53,000
- In twelve years with NCF of 58,000
- If this were a one-time-only deal, you would
simply calculate the NPV of each alternative - NPV of cutting in ten years 15,132.74
- NPV of cutting in eleven years
15,236.23 - NPV of cutting in twelve years
14,887.16
26Mutually exclusive projects with different
Starting Times
- But, more realistically, you will be able to
continue cutting down these trees every ten,
eleven, or twelve years. Which is the best
alternative as a repetitive procedure? - The question is, what is better
- (1) receiving an annuity of 47,000 every ten
years - (2) receiving an annuity of 53,000 every eleven
years - (3) receiving an annuity of 58,000 every twelve
years
27Mutually exclusive projects with different
Starting Times
- For any set of reproducible mutually exclusive
projects with different lives, you can - Find the NPV of each project through one
repetition, and then find its Equivalent Annual
Cash Flow (EACF), and choose the one with the
highest EACF. - Where EACF is calculated as that fixed
payment (annuity) having the same value and life
of the project. - So
- EACF(10) 2,678.12
- EACF(11) 2,566.98
-
- EACF(12) You know this isn't the right one
since it has a lower present value but takes
longer to produce - Thus you want to take the shorter lived project
now.
28Replacement Decision
- Return to the first example, you choose project
(2), and now you are in the fifth year of that
project. The project, as expected, is returning
19.5 million this year. But production
difficulties have resulted in a machine which is
wearing out faster than anticipated. So that
your expected cash flow for the next five years
will be - 0 1
2 3 4 5 - Cash Flow 19.5 18 17 16 15
- NPV of operating
- Cash Flows 62.54 50.54 38.61
26.24 13.39
29Replacement Decision
- A new production technology has been devised
which will cost 100 million and generate 39
million for the next 7 years, with an anticipated
scrap value of 3 million at the end of the
seventh year. Should you replace the machine
now, never, or plan to replace it some time in
the future? - It is assumed that the scrap value of the old
machine will be 0 if not replaced during the next
5 years (the life of the old project), but can be
sold for 3 million at any time during the next
five years. The discount rate is assumed to be
12.
30Replacement Decision
- Find the equivalent annual cash flow for the new
machine, net of the current scrap value. - Net Cash Flow of Replacement
Machine - 0 1 2 3 4 5 6 7
- -97 39 39 39 39 39 39 42
- NET PRESENT VALUE 82.344 million
- EQUIVALENT ANNUAL CASH FLOW 18.043 million
- IRR 35.56
31Replacement Decision
- Replace in the beginning of year 2. Note, simply
comparing NPV will not give the right answer,
neither will looking at incremental cash flow.
This is because the replacement has a different
life than the current process and they are
obviously mutually exclusive. Furthermore, and
more important, the alternatives of replacing now
versus not replacing now is not the appropriate
alternatives. You can also replace next year,
the year after, etc. The alternative which gives
the greatest incremental value relative to all
the other possible alternatives could be
calculated by looking at the incremental cash
flows from each alternative. But it is easier to
simply calculate the EACF and compare that to the
current cash flow to see what to do.
32Replacement Decision
- In general, Equivalent Annual Cash Flow or Cost
is used to consider a problem where the
investment is considered ongoing and you have to
examine what happens at the end of the project's
life. All that EACF does is help you discover
the decision which gives the highest NPV as a
whole. - STOP
33Capital Rationing
- In this situation, the decision maker is faced
with a limited capital budget. As a result, it
may not be possible to take all positive net
present value projects. Under this scenario, the
problem is to find that combination of projects
(within the capital budgeting constraint) that
leads to the highest Net Present Value. - The problem here is that the number of
possibilities become very large with a relatively
small number of projects. Thus, in order to make
the problem "manageable", we can systematize the
search.
34Capital Rationing
- Since we have a constraint, what we want to do is
invest in those projects which gives us the
highest BENEFIT per dollar invested. (The
highest bang per buck). What is the benefit?, it
is the Present Value of the Cash Flows. So that
we would want to choose that set of projects
within the capital budgeting constraint that
gives the highest - Net Present Value
- INVESTMENT
- This ratio is called the profitability Index.
35Capital Rationing
- For example, suppose we have a 13 million
capital budgeting constraint, with 7 alternative
capital budgeting projects with the following
projections. - Project NPV Investment
- A 10 15
- B 8 10
- C 4 2.5
- D 6 5
- E 5 2.5
- F 7 5
- G 4.5 3
36Capital Rationing
- Rank by Profitability Index (NPV/INV
- Project Profitability Index
Investment Total -
- E 2.0
2.5 2.5 - C 1.6 2.5 5.0
- G 1.5 3
8.0 - F 1.4
5 13.0 D
1.2 5 - B .8 10
- A .667 15
- COMBINATION WITH HIGHEST PROFITABILITY INDEX
WITHIN THE CAPITAL BUDGET - (E,C,G,F) has a NPV of 20.5 million, and a cost
of 13 million.
37Capital Rationing
- However, if the budget were 15 million rather
than 13 million we would have a problem. Adding
D would go over the budget and be infeasible, but
the combination CDEF has a higher NPV (22
million) than the chosen combination of ECGF.
This is because the amount spent was only 13
million leaving 2 million in unspent funds. In
this case, we are better off choosing a
combination which spends all the funds. - THE ONLY WAY TO DO THIS RIGHT IS TO DO A FULL
BLOWN LINEAR PROGRAMING PROBLEM WITH CONSTRAINTS.
