The document discusses various capital budgeting techniques for evaluating investment projects, including payback period, discounted payback period, net present value (NPV), profitability index (PI), and internal rate of return (IRR). It explains that more sophisticated techniques like NPV, PI, and IRR are preferred because they consider the time value of money and examine all cash flows, unlike payback period which does not. The key is to accept projects whose NPV is positive, PI is above 1, or IRR exceeds the required rate of return. Capital rationing, when a firm limits capital expenditures, can be addressed through adjusting the cost of capital or using linear programming.

Capital budgeting
1. The Basics of Capital Budgeting:
Evaluating Cash Flows

2. Capital Budgeting: the process of
planning for purchases of long-
term assets.
s example:
Suppose our firm must decide whether to
purchase a new plastic molding machine
for Rs125,000. How do we decide?
s Will the machine be profitable?
s Will our firm earn a high rate of return
on the investment?

3. Decision-making Criteria in
Capital Budgeting
How do we decide
if a capital
investment
project should
be accepted or
rejected?
Indian School of Petroleum
4. Decision-making Criteria in
Capital Budgeting
s The Ideal Evaluation Method should:
a) include all cash flows that occur
during the life of the project,
b) consider the time value of money,
c) incorporate the required rate of
return on the project.

5. Future value
FVn = PV(1 + i) .

What’s the FV of an initial Rs 100
after 3 years if i = 10%?

6. After 3 years:
FV3 = PV(1 + i)3
= Rs 100(1.10)3
= Rs 133.10.

8. Payback Period
s The number of years needed to
recover the initial cash outlay.
s How long will it take for the project
to generate enough cash to pay for
itself?

11. s Is a 3.33 year payback period good?
s Is it acceptable?
s Firms that use this method will
compare the payback calculation to
some standard set by the firm.
s If our senior management had set a
cut-off of 5 years for projects like
ours, what would be our decision?
s Accept the project.

12. Drawbacks of Payback Period:
s Firm cutoffs are subjective.
s Does not consider time value of money.
s Does not consider any required rate of
return.
s Does not consider all of the project’s
cash flows.

criterion! Indian School of Petroleum
15. Discounted Payback
s Discounts the cash flows at the firm’s
required rate of return.
s Payback period is calculated using
these discounted net cash flows.
s Problems:
s Cutoffs are still subjective.
s Still does not examine all cash flows.

23. Other Methods
1) Net Present Value (NPV)
2) Profitability Index (PI)
3) Internal Rate of Return (IRR)
Each of these decision-making criteria:
s Examines all net cash flows,
s Considers the time value of money, and
s Considers the required rate of return.

24. Net Present Value
• NPV = the total PV of the annual net
cash flows - the initial outlay.
• Decision Rule:
• If NPV is positive, ACCEPT.
• If NPV is negative, REJECT.

25. NPV Example
s Suppose we are considering a capital
investment that costs Rs276,400 and provides
annual net cash flows of Rs 83,000 for four
years and Rs116,000 at the end of the fifth year.
The firm’s required rate of return is 15%.

s IRR is the rate of return that makes the

outlay.

33. Calculating IRR
s Looking again at our problem:
s The IRR is the discount rate that
makes the PV of the projected cash
flows equal to the initial outlay.

You should get IRR = 17.63%!
s This way, we have to solve for IRR by trial
and error. Indian School of Petroleum
36. IRR
• Decision Rule:
• If IRR is greater than or equal
to the required rate of return,
ACCEPT.
• If IRR is less than the required
rate of return, REJECT.

37. Capital Rationing
s Capital rationing occurs when a company
chooses not to fund all positive NPV projects.
s The company typically sets an upper limit on
the total amount of capital expenditures that it
will make in the upcoming year.
Indian School of Petroleum
38. Reason: Companies want to avoid the direct
costs (i.e., flotation costs) and the indirect costs
of issuing new capital.
Solution: Increase the cost of capital by enough
to reflect all of these costs, and then accept all
projects that still have a positive NPV with the
higher cost of capital.
Indian School of Petroleum
39. Reason: Companies don’t have enough
managerial, marketing, or engineering staff to
implement all positive NPV projects.
Solution: Use linear programming to maximize
NPV subject to not exceeding the constraints on
staffing.
Indian School of Petroleum
40. Reason: Companies believe that the project’s
managers forecast unreasonably high cash flow
estimates, so companies “filter” out the worst
projects by limiting the total amount of projects
that can be accepted.
Solution: Implement a post-audit process and tie
the managers’ compensation to the subsequent
performance of the project.
