In a forthcoming paper, Fernandez (2002) claims to derive a formula for the valuation of debt tax shields for firms with cash flows that grow perpetually at a constant rate. We show that his formula is incorrect and provide an example where his valuation would admit arbitrage

The conventional wisdom about psi, the appropriate discount rate for the tax shield, is as follows. If the tax shield is risk-free, that is, the revenue is sufficient to ensure that the interest deduction will be used with full certainty in the relevant period, then the appropriate discount rate...

There are two ways to view the inter-temporal risk profile of a finite stream of cash flows that is represented by a binomial process. We can examine the risk profile of the cash flow process or the value process that is derived from the cash flow process. First, with respect to a given year n,...

In a recent paper, Ruback (2000) assumes that the discount rate for the tax shield in the Adjusted Present Value (APV) approach is the cost of debt and shows that the Capital Cash Flow (CCF) method and the Adjusted Present Value (APV) approach give different answers for the levered value. In...

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...

There are methods to match value added approaches (Residual Income Method, RIM and Economic Value Added, EVA) with discounted cash flow methods, DCF. In this note we use a real life case from an emerging country to illustrate the matching, with complexities such as unpaid taxes, losses carried...
