CHAPTER 18 CASE C-2
Step 2: Calculating the present value of the unlevered cash flows beyond the first five years.
The assumption given is that the cash flows will grow at 3.5 percent into perpetuity. Again, we discount
these cash flows at the unlevered return on equity. So, the value of these cash flows in Year 5 will be:
Unlevered CF value in Year 5 = [$1,756.84(1 + .035)]/(.14 – .035)
Step 3: Calculating the present value of interest tax shields for the first five years.
The interest tax shield each year is the interest paid times the tax rate. To find the present value of the
interest tax shield, we need to discount these at the pretax cost of debt, so the present value of the interest
tax shield for the first five years is:
Step 4: Calculating the present value of interest tax shields beyond the first five years.
Finally, we must calculate the value of tax shields associated with debt used to finance the operations of
the company after the first five years. The assumption given in the case is that debt will be reduced and
maintained at 25 percent of the value of the firm from that date forward. Under this assumption, it is
appropriate to use the WACC method to calculate a terminal value for the firm at the target capital structure.
This, in turn, can be decomposed into an all-equity value and a value from tax shields. Note that we need
to use the interest rate on the debt beyond Year 5 in these calculations. If the capital structure changes after
the first five years, the levered cost of equity can be found with Modigliani-Miller Proposition II with
corporate taxes:
RS = R0 + (B/S)(R0 – RB)(1 – TC)
