k. 4. Now assume that the cost to replicate Project T in 2 years will increase to
$105,000 because of inflationary pressures. How should the analysis be handled
now, and which project should be chosen?
Answer: If the cost of Project T is expected to increase, the replication project is not identical
to the original, and the EAA approach cannot be used. In this situation, we would put
the cash flows on a time line as follows:
With this change, the common-life NPV of Project T is less than that for Project F,
and hence Project F should be chosen.
l. You are also considering another project which has a physical life of 3 years; that
is, the machinery will be totally worn out after 3 years. However, if the project
were terminated prior to the end of 3 years, the machinery would have a positive
salvage value. Here are the project’s estimated cash flows:
Initial Investment End-of-Year
And Operating Net Salvage
Year Cash Flows Value
0 ($5,000) $5,000
1 2,100 3,100
2 2,000 2,000
3 1,750 0
Using the 10% cost of capital, what is the project’s NPV if it is operated for the
full 3 years? Would the NPV change if the company planned to terminate the
project at the end of Year 2? At the end of Year 1? What is the project’s optimal
(economic) life?
Answer: Here are the time lines for the 3 alternative lives:
No termination:
