Title: Capital Budgeting Topics Investments of Unequal Lives
1Capital Budgeting Topics Investments of Unequal
Lives
- There are times when application of the NPV rule
can lead to the wrong decision. Consider an
investment in equipment required in the
production process - There are two choices
- The Auto Machine costs 40,000 today, has
annual operating costs of 1,000 and lasts for 10
years. - The Manual Machine costs 10,000 today, has
annual operating costs of 5,000 and lasts for 5
years. - Which one should we choose?
2Investments of Unequal Lives
- At first glance, the Manual has the lower NPV
(r 10)
This overlooks the fact that the Auto Machine
lasts twice as long. When we incorporate that,
the Auto Machine is actually cheaper.
3Investments of Unequal Lives - Replacement Chain
- The Manual Machine time line of cash flows over
ten years with a replacement at the end of its
life
4Investments of Unequal Lives
- Replacement Chain - Matching Cycle
- Repeat the projects forever, find the PV of that
perpetuity. - Assumption Both projects can and will be
repeated. - Repeat projects until they begin and end at the
same timelike we just did with the air cleaners. - Compute NPV for the repeated projects.
- The Equivalent Annual Cost Method
5Investments of Unequal Lives EAC
- The Equivalent Annual Cost Method
- Applicable to a much more robust set of
circumstances than replacement chain. - The Equivalent Annual Cost is the value of the
level payment annuity that has the same PV as our
original set of cash flows. - NPV EAC annuity factor

- For example, the EAC for the Auto Machine is
- Using the annuity factor
7Financial Leverage and Beta
- Financial leverage is the sensitivity of a firms
fixed costs of financing. - The relationship between the betas of the firms
debt, equity, and assets is given by
- Financial leverage always increases the equity
beta relative to the asset beta.
8Financial Leverage and Beta Example
- The XYZ, Inc., is currently all-equity and it has
a beta of 1.10. - The firm has decided to lever up to a capital
structure of 25 debt and 75 equity. - Since the firm will remain in the same industry,
its asset beta should remain 0.90. - However, assuming a zero beta for its debt, its
equity beta would become twice as large
9The Project versus the Firm
- Any projects cost of capital depends on the use
(the project) to which the capital is being
putnot the source of capital. - Therefore, it depends on the risk of the project
and not the risk of the firm.
10Capital Budgeting Project Risk
Project IRR
Hurdle rate
Firms risk (beta)
- A firm that uses one discount rate for all
projects may over time increase the risk of the
firm while decreasing its value.
11Capital Budgeting Project Risk
- Suppose a firm is made of three equal size
departments. The companys cost of equity capital
is based on the CAPM. The risk-free rate is 4
the market risk premium is 10 - The breakdown of the companys departments.
Electronic parts dep. b 1.1Electric
equipment dep. b 1.4Computer parts dep. b
2.0
Average b of assets 1.5
Cost of Equity 4 1.5 14 4 19 When
evaluating a new computer parts project, which
cost of capital should be used?
12Capital Budgeting Project Risk
- Suppose a computer part project with an IRR of
20 is accepted. - It will change the firm division into 50
computer parts and 25 for each other department.
-
New Average b of assets 1.725
The firm required return 4 1.72510
21.25 Which is definitely above the firm actual
return
13The Cost of Capital with Debt
- The Weighted Average Cost of Capital is given by
- It is because interest expense is tax-deductible
that we multiply the last term by (1- tC) making
the true cost of debt rD(1- tC)
14Estimating Widget Inc. Cost of Capital
- First, we estimate the cost of equity and the
cost of debt. - We estimate an equity beta to estimate the cost
of equity. - We can often estimate the cost of debt by
observing the YTM of the firms debt. - Second, we determine the WACC by weighting these
two costs.
15Estimating Widgets Cost of Capital
- The industry average beta is 1.30 the risk free
rate is 4 and the market risk premium is 5.6. - Thus the cost of equity capital is
16Estimating Widgets Cost of Capital
- The yield on the companys debt is 7.2
(relative to similar maturity treasury bonds and
credit risk) and the firm is in the 36 marginal
tax rate. - The debt is 26 of the total firm value
9.55 percent is Widgets cost of capital. It
should be used to discount any project where the
projects risk is equal to the risk of the firm
as a whole, and the project is financed with the
same leverage as the whole firm.
