18–16. You are evaluating a project that requires an investment of $90 today and provides a single cash
flow of $115 for sure one year from now. You decide to use 100% debt financing, that is, you will
borrow $90. The risk-free rate is 5% and the tax rate is 40%. Assume that the investment is fully
depreciated at the end of the year, so without leverage you would owe taxes on the difference
between the project cash flow and the investment, that is, $25.
a. Calculate the NPV of this investment opportunity using the APV method.
b. Using your answer to part a, calculate the WACC of the project.
c. Verify that you get the same answer using the WACC method to calculate NPV.
d. Finally, show that flow-to-equity also correctly gives the NPV of this investment opportunity.
a. FCF at year end (after tax) = 115 – 0.40 25 = 105
b. ru = rd = 5%, d = 90/101.71
18–17. Tybo Corporation adjusts its debt so that its interest expenses are 20% of its free cash flow. Tybo
is considering an expansion that will generate free cash flows of $2.5 million this year and is
expected to grow at a rate of 4% per year from then on. Suppose Tybo’s marginal corporate tax
rate is 40%.
a. If the unlevered cost of capital for this expansion is 10%, what is its unlevered value?
b. What is the levered value of the expansion?
c. If Tybo pays 5% interest on its debt, what amount of debt will it take on initially for the
expansion?
d. What is the debt-to-value ratio for this expansion? What is its WACC?
e. What is the levered value of the expansion using the WACC method?
