Should we build this plant?

What is capital budgeting?

• Analysis of potential additions to fixed assets.
• Long-term decisions involve large expenditures.
• Very important to firms future.

3
Steps

• 1. Estimate CFs (inflows outflows).
• 2. Assess riskiness of CFs.
• 3. Determine k WACC (adj.).
• 4. Find NPV and/or IRR.
• 5. Accept if NPV gt 0 and/or IRR gt WACC.

4
What is the difference between independent and
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.

5
An Example of Mutually Exclusive Projects
BRIDGE vs. BOAT to get products across a river.
6
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. Nuclear power plant, strip
mine.

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

Strengths of Payback
1. Provides an indication of a projects risk and
liquidity. 2. Easy to calculate and understand.
Weaknesses of Payback
1. Ignores the TVM. 2. Ignores CFs occurring
after the payback period.
12
Discounted Payback Uses discounted rather than
raw CFs.

Rationale for the NPV Method
NPV PV inflows Cost Net gain in
wealth. Accept project if NPV gt 0. Choose
between mutually exclusive projects on basis
of higher NPV. Adds most value.
17
Using NPV method, which project(s) should be
accepted?

• If Projects S and L are mutually exclusive,
  accept S because NPVs gt NPVL .
• If S L are independent, accept both NPV gt 0.

Q. How is a projects IRR related to a bonds

A. They are the same thing. A bonds YTM is the
IRR if you invest in the bond.

23
Rationale for the IRR Method
If IRR gt WACC, then the projects rate of return
is greater than its cost--some return is left
over to boost stockholders returns. Example WAC
C 10, IRR 15. Profitable.
24
IRR Acceptance Criteria

• If IRR gt k, accept project.
• If IRR lt k, reject project.

25
Decisions on Projects S and L per IRR

• If S and L are independent, accept both. IRRs gt
  k 10.
• If S and L are mutually exclusive, accept S
  because IRRS gt IRRL .

Construct NPV Profiles

different discount rates

Two Reasons NPV Profiles Cross
1. 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 k favors small
projects. 2. Timing differences. Project with
faster payback provides more CF in early years
for reinvestment. If k is high, early CF
especially good, NPVS gt NPVL.
31
Reinvestment Rate Assumptions

• NPV assumes reinvest at k (opportunity cost of
  capital).
• IRR assumes reinvest at IRR.
• Reinvest at opportunity cost, k, is more
  realistic, so NPV method is best. NPV should be
  used to choose between mutually exclusive
  projects.

32
Managers like rates--prefer IRR to NPV
comparisons. Can we give them a better IRR?
Yes, MIRR is the discount rate that causes the PV
of a projects 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.

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.

IRR ERROR. Why?
37
We got IRR ERROR because there are 2 IRRs.

38
Logic of Multiple IRRs
1. At very low discount rates, the PV of CF2 is
large negative, so NPV lt 0. 2. At very high
discount rates, the PV of both CF1 and CF2 are
low, so CF0 dominates and again NPV lt 0. 3. In
between, the discount rate hits CF2 harder than
CF1, so NPV gt 0. 4. Result 2 IRRs.
39
Could find IRR with calculator 1. Enter CFs as
before. 2. Enter a guess as to IRR by storing
the guess. Try 10 10 STO IRR 25
lower IRR Now guess large IRR, say,
200 200 STO IRR 400 upper IRR
