In Discounted Cash Flow valuations, the WACC approach is very popular. Therefore, knowing which limitations the concept inherits is essential. The objective of this paper is thus twofold: First, it is clarified that a constant WACC rate must fail if the implied leverage ratio is time-varying. This seems to be the rationale for defining a nonlinear WACC (NLWACC). However, the NLWACC appears to be rather artificial when allowing for time-varying WACCs. Second, although the NLWACC approach is
further amplified in this paper, it must be emphasized that this approach is, even then, applicable only under specific conditions while a time-varying WACC is still able to provide reliable results. In conclusion, the WACC approach is a valid workhorse whose results can be economically interpreted.
