Fernandez [2004; The value of tax shields is NOT equal to the present value of tax shields. Journalof Financial Economics, 73, 145–165] claims to derive a formula for the valuation of debt tax shieldsfor firms with cash flows that growperpetually at a constant rate.We showthat his formula is...

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...

In this article we use a real life case from an emerging country to illustrate the valuation with discounted cash flow methods that include complexities such as unpaid taxes, losses carried forward, foreign exchange debt, presumptive income and inflation adjustments to the Financial Statements....

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...
