The value of tax shields is the difference between the present values of two different cash flows, each with their own risk: the present value of taxes for the unlevered company and the present value of taxes for the levered company. For constant growth companies, the value of tax shields in a...

It is a well known problem the interactions between the market value of cash flows and the discount rate (usually the weighted average cost of capital, WACC) to calculate that value. This is mentioned in almost all textbooks in corporate finance. However, the solution adopted by most authors is...

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

We value a company that targets its capital structure in book-value terms. This capital structure definition provides us with a Value of Tax Shields that lies between those of Modigliani-Miller (fixed debt) and Miles-Ezzell (fixed market-value leverage ratio). If a company targets its leverage...

This paper corrects some equations of Farber, Gillet and Szafarz (2006). The WACC is a discount rate widely used in corporate finance. However, the correct calculation of the WACC rests on a correct valuation of the tax shields. The value of tax shields depends on the debt policy of the company....

Debt financing with subsidizes interest rate has a multidimensional impact on the firm. Value of the levered equity, value of the debt and overall firm value will be different of those values with debt financing at market rate. Subsidized interest rate on debt does not create any additional cash...

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), a fixed market-value leverage ratio. The value of tax shields depends only on the present value of the net increases of debt....

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...

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...

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...
