In investment appraisal, uncertainty can be managed through intervals or fuzzy numbers because the arithmetical properties and the extension principle are well established and can be successfully applied in a rigorous way. We apply interval and fuzzy numbers to the Average Internal Rate of...

I present a set of conditions for defining risky debt associated to cash flow and not to accounting earnings. I explain why realization of tax shields for finite cash flows in any period of time t are correlated to Earnings before Interest and Taxes and are not correlated to interest expenses at...

In these slides we discuss the practical and conceptual difficulty of finding an Optimal Capital Structure. We propose a normative approach we call Implicit Bankruptcy Costs Theory and how to proceed to find the optimal capital structure and value with period-to-period constant and variable...

Muchos consultores, autores y profesores de Finanzas incluyen los cambios en losactivos liquidos (dividendos potenciales") en los flujos de caja. Esta practica escontraria a la teoria basica de las finanzas. Presentamos razones economicas, teoricas, yempiricas para apoyar la tesis. Por lo tanto,...

In cash flow valuation, on grounds of simplicity, it is common to assume that the leverage is constant over time. With constant leverage, the return to levered equity is constant and consequently, the Weighted Average Cost of Capital (WACC) applied to the Free Cash Flow is constant. However,...

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...

In this paper we find restrictions for the value of a parameter used in defining the cost of capital for perpetuities and terminal values: the growth rate for the free cash flow. When defining the growth rate for the free cash flow the usual warning is to set it below the growth of the economy...

This paper presents a formulation for the cost of equity, the WACC, and the value of equity and firm for growing perpetuities without circularity, using some previous results. We also derive a relationship between leverage, D%, and growth, given a value of debt at instant zero.

We argue that the Economic Value Added (EVA) is biased by design and will generally yield distorted assessment of both the operating and overall performance. Fundamentally, the scale of measurement bias depends on the interest tax shield actually obtained in a measurement period and on a book to...
