We develop valuation formulae for a company that maintains a fixed book-value leverage ratio and claim that it is more realistic than to assume, as Miles-Ezzell (1980) do, a fixed market-value leverage ratio. The value of tax shields depends only on the present value of the net increases of...

I correct some expressions in Fernández (2004) and provide a more general expression for the value of tax shields. This expression is the difference between the present values of two different cash flows, each with its own risk: the present value of taxes for the unlevered company and the...

The Comment is thought provoking and helps a lot in rethinking the value of tax shields. However, the conclusion of Fieten, Kruschwitz, Laitenberger, Löffler, Tham, Vélez-Pareja and Wonder (2005) is not correct because, as will be proven below, the main result of Fernández (2004) is correct...

There is a wealth of literature about discounted cash flow valuation. In this paper, we will discuss the most important papers, highlighting those that propose different expressions for the value of the tax shield (VTS). The discrepancies between the various theories on the valuation of a...

The value of tax shields depends only on the nature of the stochastic process of the net increases of debt. The value of tax shields in a world with no leverage cost is the tax rate times the current debt plus the present value of the net increases of debt. We develop valuation formulae for a...

The value of tax shields depends only on the nature of the stochastic process of the net increases of debt. The value of tax shields in a world with no leverage cost is the tax rate times the current debt plus the present value of the net increases of debt. By applying this formula to specific...
