What is capital budgeting? Analysis of potential projects. Long-term decisions; involve large
expenditures. Very important to firm’s future.
![Page 5: THE BASICS OF CAPITAL BUDGETING](https://reader036.vdocuments.mx/reader036/viewer/2022062307/5562c7ded8b42aaf178b5162/html5/thumbnails/5.jpg)

Steps in Capital Budgeting Estimate cash flows (inflows &
outflows). Assess risk of cash flows. Determine r = WACC for project. Evaluate cash flows.

Independent versus Mutually Exclusive Projects Projects are:
independent, if the cash flows of one are unaffected by the acceptance of the other.
mutually exclusive, if the cash flows of one can be adversely impacted by the acceptance of the other.

Rationale for the NPV Method NPV = PV inflows – Cost
This is net gain in wealth, so accept project if NPV > 0.
Choose between mutually exclusive projects on basis of higher positive NPV. Adds most value.
![Page 13: THE BASICS OF CAPITAL BUDGETING](https://reader036.vdocuments.mx/reader036/viewer/2022062307/5562c7ded8b42aaf178b5162/html5/thumbnails/13.jpg)
13
Using NPV method, which franchise(s) should be accepted?
If Franchises S and L are mutually exclusive, accept S because NPVs > NPVL.
If S & L are independent, accept both; NPV > 0.
NPV is dependent on cost of capital.
![Page 14: THE BASICS OF CAPITAL BUDGETING](https://reader036.vdocuments.mx/reader036/viewer/2022062307/5562c7ded8b42aaf178b5162/html5/thumbnails/14.jpg)

IRR is an estimate of the project’s rate of return, so it is comparable to the YTM on a bond.

19
Rationale for the IRR Method If IRR > WACC, then the project’s
rate of return is greater than its cost-- some return is left over to boost stockholders’ returns.
Example:
WACC = 10%, IRR = 15%. So this project adds extra return to
shareholders.
![Page 20: THE BASICS OF CAPITAL BUDGETING](https://reader036.vdocuments.mx/reader036/viewer/2022062307/5562c7ded8b42aaf178b5162/html5/thumbnails/20.jpg)
20
Decisions on Franchises S and L per IRR
If S and L are independent, accept both: IRRS > r and IRRL > r.
If S and L are mutually exclusive, accept S because IRRS > IRRL.
IRR is not dependent on the cost of capital used.
![Page 21: THE BASICS OF CAPITAL BUDGETING](https://reader036.vdocuments.mx/reader036/viewer/2022062307/5562c7ded8b42aaf178b5162/html5/thumbnails/21.jpg)

25
To Find the Crossover Rate Find cash flow differences between the
projects. See data at beginning of the case. Enter these differences in CFLO register,
then press IRR. Crossover rate = 8.68%, rounded to 8.7%.
Can subtract S from L or vice versa and consistently, but easier to have first CF negative.
If profiles don’t cross, one project dominates the other.
![Page 26: THE BASICS OF CAPITAL BUDGETING](https://reader036.vdocuments.mx/reader036/viewer/2022062307/5562c7ded8b42aaf178b5162/html5/thumbnails/26.jpg)
26
Two Reasons NPV Profiles Cross Size (scale) differences. Smaller project
frees up funds at t = 0 for investment. The higher the opportunity cost, the more valuable these funds, so high r favors small projects.
Timing differences. Project with faster payback provides more CF in early years for reinvestment. If r is high, early CF especially good, NPVS > NPVL.
![Page 27: THE BASICS OF CAPITAL BUDGETING](https://reader036.vdocuments.mx/reader036/viewer/2022062307/5562c7ded8b42aaf178b5162/html5/thumbnails/27.jpg)
27
Reinvestment Rate Assumptions
NPV assumes reinvest at r (opportunity cost of capital).
IRR assumes reinvest at IRR. Reinvest at opportunity cost, r, is
more realistic, so NPV method is best. NPV should be used to choose between mutually exclusive projects.
![Page 28: THE BASICS OF CAPITAL BUDGETING](https://reader036.vdocuments.mx/reader036/viewer/2022062307/5562c7ded8b42aaf178b5162/html5/thumbnails/28.jpg)
28
Modified Internal Rate of Return (MIRR)
MIRR is the discount rate that causes the PV of a project’s terminal value (TV) to equal the PV of costs.
TV is found by compounding inflows at WACC.
Thus, MIRR assumes cash inflows are reinvested at WACC.
![Page 29: THE BASICS OF CAPITAL BUDGETING](https://reader036.vdocuments.mx/reader036/viewer/2022062307/5562c7ded8b42aaf178b5162/html5/thumbnails/29.jpg)

31
To find TV with 12B: Step 1, Find PV of Inflows First, enter cash inflows in CFLO
register:CF0 = 0, CF1 = 10, CF2 = 60, CF3 = 80
Second, enter I/YR = 10.
Third, find PV of inflows:Press NPV = 118.78
![Page 32: THE BASICS OF CAPITAL BUDGETING](https://reader036.vdocuments.mx/reader036/viewer/2022062307/5562c7ded8b42aaf178b5162/html5/thumbnails/32.jpg)
32
Step 2, Find TV of Inflows
Enter PV = -118.78, N = 3, I/YR = 10, PMT = 0.
Press FV = 158.10 = FV of inflows.
![Page 33: THE BASICS OF CAPITAL BUDGETING](https://reader036.vdocuments.mx/reader036/viewer/2022062307/5562c7ded8b42aaf178b5162/html5/thumbnails/33.jpg)
33
Step 3, Find PV of Outflows
For this problem, there is only one outflow, CF0 = -100, so the PV of outflows is -100.
For other problems there may be negative cash flows for several years, and you must find the present value for all negative cash flows.
![Page 34: THE BASICS OF CAPITAL BUDGETING](https://reader036.vdocuments.mx/reader036/viewer/2022062307/5562c7ded8b42aaf178b5162/html5/thumbnails/34.jpg)
34
Step 4, Find “IRR” of TV of Inflows and PV of Outflows
Enter FV = 158.10, PV = -100, PMT = 0, N = 3.
Press I/YR = 16.50% = MIRR.
![Page 35: THE BASICS OF CAPITAL BUDGETING](https://reader036.vdocuments.mx/reader036/viewer/2022062307/5562c7ded8b42aaf178b5162/html5/thumbnails/35.jpg)
35
Why use MIRR versus IRR?
MIRR correctly assumes reinvestment at opportunity cost = WACC. MIRR also avoids the problem of multiple IRRs.
Managers like rate of return comparisons, and MIRR is better for this than IRR.
![Page 36: THE BASICS OF CAPITAL BUDGETING](https://reader036.vdocuments.mx/reader036/viewer/2022062307/5562c7ded8b42aaf178b5162/html5/thumbnails/36.jpg)
36
Profitability Index
The profitability index (PI) is the present value of future cash flows divided by the initial cost.
It measures the “bang for the buck.”

What is the payback period?
The number of years required to recover a project’s cost,
or how long does it take to get the business’s money back?

Strengths and Weaknesses of Payback Strengths:
Provides an indication of a project’s risk and liquidity.
Easy to calculate and understand. Weaknesses:
Ignores the TVM. Ignores CFs occurring after the payback
period. No specification of acceptable payback.

Normal vs. Nonnormal Cash Flows Normal Cash Flow Project:
Cost (negative CF) followed by a series of positive cash inflows.
One change of signs. Nonnormal Cash Flow Project:
Two or more changes of signs. Most common: Cost (negative CF), then string
of positive CFs, then cost to close project. For example, nuclear power plant or strip
mine.

48
Logic of Multiple IRRs At very low discount rates, the PV of
CF2 is large & negative, so NPV < 0. At very high discount rates, the PV
of both CF1 and CF2 are low, so CF0 dominates and again NPV < 0.
In between, the discount rate hits CF2 harder than CF1, so NPV > 0.
Result: 2 IRRs.

Equivalent Annual Annuity Approach (EAA) Convert the PV into a stream of
annuity payments with the same PV. S: N=2, I/YR=10, PV=-4.132, FV = 0.
Solve for PMT = EAAS = $2.38. L: N=4, I/YR=10, PV=-6.190, FV = 0.
Solve for PMT = EAAL = $1.95. S has higher EAA, so it is a better
project.

Put Projects on Common Basis Note that Franchise S could be
repeated after 2 years to generate additional profits.
Use replacement chain to put on common life.
Note: equivalent annual annuity analysis is alternative method.

Economic Life versus Physical Life Consider another project with a 3-
year life. If terminated prior to Year 3, the
machinery will have positive salvage value.
Should you always operate for the full physical life?
See next slide for cash flows.

Conclusions
The project is acceptable only if operated for 2 years.
A project’s engineering life does not always equal its economic life.

Choosing the Optimal Capital Budget
Finance theory says to accept all positive NPV projects.
Two problems can occur when there is not enough internally generated cash to fund all positive NPV projects: An increasing marginal cost of capital. Capital rationing

66
Increasing Marginal Cost of Capital
Externally raised capital can have large flotation costs, which increase the cost of capital.
Investors often perceive large capital budgets as being risky, which drives up the cost of capital.

67
If external funds will be raised, then the NPV of all projects should be estimated using this higher marginal cost of capital.

Capital Rationing Capital rationing occurs when a
company chooses not to fund all positive NPV projects.
The company typically sets an upper limit on the total amount of capital expenditures that it will make in the upcoming year.

69
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.(More...)

70
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.

71
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.
