This document contains 9 practice problems related to capital budgeting. Problem 9 provides details on a project being considered by Acme Mfg including the probability distribution of annual cash flows under different scenarios. Based on the coefficient of variation of NPV, the risk-adjusted discount rate for the project would be 12%. Using this rate, the expected NPV is negative $32.35 so the project should be rejected.

1. Capital budgeting practice problems.
1. Evaluation of Cash Flows. Below are the cash flows for two mutually exclusive
projects.

2. 3. Expansion Project. A machine has a cost of $180. It will have a life of 3 years, and
will be depreciated straight line to zero salvage value. It will result in sales revenue of
$200 per year and cash operating costs of $110 per year. Use of the machine will
require an increase in working capital of $70 for the 3 years, beginning at year 0. The
appropriate discount rate is 8% and the firm’s tax rate is 40%.

4. Inflation adjustment: A project requires an initial investment of $8,000, has a 4-year
life and provides expected cash flows as follows, based on year 1 prices and costs:
annual revenue = $5,000
annual cash operating costs = $2,000
annual depreciation = $2,000
terminal cash flow = 0
cost of capital = 14%
T = 30%
a. Calculate the annual operating cash flows without adjusting for inflation. (Are these
cash flows real or nominal?) Calculate the associated NPV.
b. Adjust the cash flows to reflect the effects of inflation, which is expected to affect sales
revenue and cash operating expenses at the rate of 4% annually. (Are these cash flows
real or nominal?) Calculate the associated NPV.
c. Which NPV is the correct one for evaluating the project?
a. -$133; b. $202
5. Mutually Exclusive Projects with Unequal Lives. Murray’s Coffee House is trying
to choose between two new coffee bean roasters. The required rate of return for either
machine is 10%. Shown below are the after-tax cash flows associated with each
machine:

3. 6. Risk Adjustment and Project Selection. Acme Mfg is considering two projects, A &
B, with cash flows as shown below:

2 20,000 25,000
3 20,000 25,000
4 20,000 25,000
The opportunity cost of capital for A is 14 percent. The opportunity cost of capital for B is
10 percent.
a. Calculate the NPV for each project.
b. Calculate the IRR for each project.
c. Which project(s) should be accepted in each of the following situations:
(1) The projects are mutually exclusive and there is no capital constraint.
(2) The projects are independent and there is no capital constraint.
(3) The projects are independent and there is a total of $100,000 of financing for
capital outlays in the coming period.
d. Explain why the cost of capital for A might be higher than for B.
Answers: a. NPVA = $8,274, NPVB = $11,065; b. IRRA = 21.86%, IRRB = 16.08%
7. Cost of Capital. Delta, Inc. has a stock price of $50. In the fiscal year just ended,
dividends were $2.00. Earnings per share and dividends are expected to increase at an
annual rate of 8 percent. The risk-free rate is 4 percent, the market risk premium is 6.4
percent and the beta on Delta’s stock is 1.25. Delta’s target capital structure is 40% debt
and 60% common equity. Delta’s tax rate is 40 percent.
New common stock can be sold to net $40 per share after flotation costs.
Delta can sell bonds that mature in 25 years with a par value of $1,000 and an 8%
coupon rate paid annually for $960.

4. 8. Replacement project: Existing machine was purchased 2 years ago at a cost of
$3,200. It is being depreciated straight line over its 8 year life. It can be sold now for
$3,000 or used for 6 more years at which time it will be sold for an estimated $500. It
provides revenue of $5,000 annually and cash operating costs of $2,000 annually.
A replacement machine can be purchased now for $7,800. It would be used for 6 years,
and depreciated straight line. It will result in additional sales revenue of $1,500 annually,
but because of its increased efficiency it would reduce cash operating costs by $600 per
year. The new machine would require additional inventories of $700, and accounts
receivable would increase by $300. Its expected salvage value in 6 years is $2,000.
The tax rate is 40% and the required rate of return is 13%. Should the old machine be
replaced?
a. Calculate the incremental cash flow at time 0.
b. Calculate the incremental annual operating cash flows that result from the new
machine.
