3. What is capital budgeting?
A process for determining the profitability of a capital investment.
Long-term decisions; involve large expenditures.
Very important to firm’s future.

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

5. Independent vs. 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.

6. What does this represent?= ∑ n
t = 0
CFt
(1 + r)t

7. NPV: Sum of the PVs of all cash flows.∑ n
t = 0
CFt
(1 + r)t
Cost often is CF0 and is negative.
NPV = ∑ n
t = 1
CFt
(1 + r)t
- CF0

11. Which project should be chosen?
What if mutually exclusive? L or S?
What if independent projects? L or S?

13. 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 NPV. Adds most value.

14. Using NPV method, which project(s) should be accepted?
If project S and L are mutually exclusive, accept S because
NPVs > NPVL .
If S & L are independent, accept both; NPV > 0.

15. Internal Rate of Return: IRR1 2 3

IRR is the discount rate that forces
PV inflows = cost. This is the same
as forcing NPV = 0.

16. NPV: Enter r, solve for NPV.∑ n

IRR: Enter NPV = 0, solve for IRR.

21. Decisions on Projects S and L per IRR
IRRS = 18% IRRL = 23%
WACC = 10%
If S and L are independent, what to do?
If S and L are mutually exclusive, what to do?

22. 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.

23. Reinvestment Rate Assumptions
NPV assumes reinvest at r (opportunity cost of capital).
IRR assumes reinvest CFs 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.

24. Modified Internal Rate of Return (MIRR)
MIRR is the discount rate which causes the PV of a project’s terminal value (TV) to equal the PV of costs.
TV is found by compounding (FV) inflows at the WACC.
Thus, MIRR assumes cash inflows are reinvested at the WACC.

25. MIRR for project L: First, find PV and TV (r = 10%)

27. To find TV with calculator: Step 1, find PV of Inflows
First, enter cash inflows in CF register:
CF0 = 0, CF1 = 10, CF2 = 60, CF3 = 80
Second, enter I = 10.
Third, find PV of inflows:
Press NPV =

28. Step 2, find TV of inflows. Enter PV = -118.78, N = 3, I = 10
CPT FV = = FV of inflows.

29. Step 3, find PV of outflows.
For this problem, there is only one outflow, CF0 = -100, so the PV of outflows is -100.

30. Step 4, find “IRR” of TV of inflows and PV of outflows.
Enter FV = , PV = -100, N = 3.
CPT I = 16.50% = MIRR.

31. 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.

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

38. Strengths and Weaknesses of Payback
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.
