When calculating Tax Savings, TS, we are confronted with a strange mix of accounting accrual and market value when involving TS in the calculation of the Weighted Average Cost of Capital, WACC, or the Cost of Equity, Ke. Firms earn the right to TS once they accrue the interest expense and they...

In this note we correct the findings reported by Vélez-Pareja and Tham (2005). Although perpetuities are somewhat artificial in the sense that in practice they do not exist, they are relevant because no matter how detailed and complex a forecasted financial plan for a firm or project could be,...

The Constant Growth Model attributed to Gordon (the Gordon Model) is one of the most known and popular models in Corporate Finance. In this work we show that even withadjustments in the calculation of the proper Weighted Average Cost of Capital, WACC, in order to grant that the model with zero...

Everybody uses tax shields when calculating the Weighted Average Cost of Capital (WACC). The textbook formula includes the tax shield with the (1-T) factor affecting the contribution of debt to the WACC. Tax shields are a strange mix of accounting and accrual related to WACC that relies on...

In this note we correct the findings reported by Vélez-Pareja and Tham (2005). Although perpetuities are somewhat artificial in the sense that in practice they do not exist, they are relevant because no matter how detailed and complex a forecasted financial plan for a firm or project could be,...

We examine the proper valuation of perpetuities without real growth. The case of a pure" non growing perpetuity (zero real growth and zero inflation) is of academic interest but in practice it might be difficult to find. The findings contradict what is generally accepted in the literature. In...

In this work we explain the proper use of perpetuities and the value of them. We consider two cases: calculating the value on period zero when the perpetuity starts with a given cash flow in period 1 and when it starts from a cash flow in period zero and it grows in period 1 at a given rate (as...

In the latest edition of Principles of Corporate Finance (Brealey, Myers and Allen, 2006) the authors use a finite cash flow example to illustrate the valuation procedure for using the Discounted Cash Flow (DCF) method with the free cash flow (FCF) and the Adjusted Present Value (APV). The two...

En este trabajo explicamos el uso apropiado de perpetuidades y el cálculo de su valor. Consideramos dos casos: calcular el valor en el período cero cuando la perpetuidad comienza con un flujo de caja dado en el período 1 y cuando se conoce el flujo de caja en el período cero y crece en el...
