In this note, we extend a numerical example in the textbook by Berk & DeMarzo that matches methods for only when KTS is equal to KD. We show that there is a generalized formulation for the return to levered equity KE that works for any value of KTS, the appropriate discount rate for the tax shield. We debunk the view that the CFE (Cash Flow to Equity) method is “apparently simple but practically confusing and useless.” Due diligence in professional valuation demands that we practice triangulation as Standard Operating Procedure (SOP). This formula is irrelevant for anyone who believes in the Pablo Fernandez (PF) approach to valuation because the concept of a “discount rate for the tax shield” is obviously nonsensical and almost surely absurd.
