We present the derivation of cost of capital under the assumption of risky tax shields discounted with the cost of levered equity. We show that the formulation is consistent and is derived from basic financial principles. This formulation is valid for finite cash flows and non growing...

This paper presents a formal derivation of general expressions for Ke and WACC in perpetuities with constant growth, which do not make any assumption on what the proper discount rate is to be applied to the firm's tax shield, and are complemented with numerical examples of its application....

This article (1) identifies three sources of risk for tax shields (TS): Two of them are associated with debt risk and one is associated with operating risk. (2) A set of conditions for defining risky debt associated with cash flow, not with earnings, is presented. (3) It further shows that...

Practitioners and some academics use potential dividends rather than actual payments toshareholders for valuing a firm´s equity. We underline the differences between the two methods and present some arguments supporting the thesis that firm valuation with potential dividends overstate the...

This paper is an extension of a previous one untitled The Correct Definition for the Cash Flows to Value a Firm (Free Cash Flow and Cash Flow to Equity) . We have added a comparative analysis between the current practice of including as cash flows amounts that belong to the Balance Sheet and the...

In this short teaching note I explain why we subtract the change in working capital from the proper item (Earnings before interest and taxes (EBIT) or Net income) in the Income Statement. I show in detail how departing from the sales revenues and the cost of goods sold we have to subtract the...

Practitioners and academics in valuation include changes in liquid assets (potential dividends) in the cash flows. This widespread and wrong practice is inconsistent with basic finance theory. We present economic, theoretical, and empirical arguments to support the thesis. Economic arguments...
