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...

Tax saving´s valuation is crucial for discounted cash flow valuation and WACC estimation. There is an ongoing debate about the appropriate discount rate for tax savings under CAPM approach. On this paper we evaluate tax savings from a contingent claim approach in order to establish a framework...

The value of debt tax shields in foundational corporate valuation models by Nobel Laureates Modigliani and Miller (MM) continues to be a controversial issue that is central to our understanding of corporate finance. This paper argues that a fundamental valuation problem exists in the MM tax...

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.

This teaching note is devoted to the definition and calculation of cash flows, namely, cash flow to debt, (CFD), cash flow to equity, (CFE), capital cash flow, (CCF), tax savings, (TS) and free cash flow, (FCF). We use the direct and the indirect methods to derive the relevant cash flow profiles...

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...

We derive and present the formula for optimal debt under the assumption that tax shields are discounted at the cost of levered equity, Ke and cash flows are on perpetuity. The formulation is consistent and is derived from basic financial principles. This formulation is valid for non-growing...
