Disregard all the assumptions made in part B, and assume there is no alternative use for the
building over the next 4 years. Now calculate the project’s NPV, IRR, MIRR, and payback. Do
these indicators suggest that the project should be accepted? Explain.
The decision criteria introduced in Chapter 11 are used to evaluate this project.
(2) How would you perform a sensitivity analysis on the unit sales, salvage value, and WACC
for the project? Assume that each of these variables deviates from its base-case, or
expected, value by plus or minus 10%, 20%, and 30%.
The base-case value for unit sales was 100,000; therefore, if you were to assume that this value
deviated by plus and minus 10%, 20%, and 30%, the unit sales values to be used in the sensitivity
analysis would be 70,000, 80,000, 90,000, 110,000, 120,000, and 130,000 units. You would then go
back to the table at the beginning of the problem, insert the appropriate sales unit number, say
70,000 units, and rework the table for the change in sales units arriving at different free cash flow
values for the project. Once you had the free cash flow values, you would calculate the NPV,
IRR, MIRR, and payback as you did previously. (Note that sensitivity analysis involves making a
change to only one variable to see how it impacts other variables.) Then, you would go back
and repeat the same steps for 80,000 units–this would be done for each of the sales unit values.
Then, you would repeat the same procedure for the sensitivity analysis on salvage value and on
WACC. (Note that for the WACC analysis, the free cash flows would remain the same, but the
WACC used in the NPV and MIRR calculations would be different.)
Excel is ideally suited for sensitivity analysis. Using data tables, the sensitivity analysis is simple.

Based on the analysis to this point, the project should not be undertaken. However, this may not
be correct, as we will see shortly.
