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...

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...

This paper shows that the Internal-Rate-of-Return (IRR) approach is unreliable, and that the recently introduced Average-Internal-Rate-of-Return (AIRR) model constitutes the basis for an alternative theoretical paradigm of rate of return. To this end, we divide the paper into two parts: a pars...

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.

Accounting measures are traditionally considered not significant from an economic point of view. In particular, accounting rates of return are often regarded economically meaningless or, at the very best, poor surrogates for the IRR, which is held to be "the" economic yield. Likewise, residual...

The IRR problem. As widely known, the IRR has serious flaws: (i)multiple real-valued IRRs may arise, (ii) the meaning of each IRR may be ambiguous (rate of return or rate of cost?), (iii)complex-valued IRRs may arise, (iv) the IRR is, in general, incompatible with the net present value (NPV) in...

Vélez-Pareja and Tham, 2003a, Vélez-Pareja and Tham, 2003b and Tham and Vélez-Pareja, 2004 showed the matching between discounted cash flow (DCF) methods and value added methods. They departed from the net operating profit less adjusted taxes NOPLAT and net income when using market values to...
