Llano-Ferro (2009) proposes a solution to avoid 'significant errors' when the Weighted Average Cost of Capital (WACC) obtained by the standard formula leads to significant errors in Net Present Value of the Firm calculations; particularly in those that apply to perpetual cash flow series. In...

In this short note, we present a nontechnical retrospection on the unbearable longevity of the classic WACC (Weighted Average Cost of Capital) for the Free Cash Flow (FCF) in perpetuity. Over the past two decades, researchers in finance have increased greatly our understanding of the properties...

When calculating the Weighted Average Cost of Capital (WACC), the well-known textbook formula includes tax shields with the (1-T) factor affecting the contribution of debt to WACC. In this work we develop a procedure for properly calculating tax shields including the case when Losses Carried...

This paper presents three different approaches for calculating the levered annual values for a finite cash flow profile. In the first approach, we use K_U, the return to unlevered equity to calculate the annual tax savings and use K_U to calculate the (present) value of the tax savings. In the...

In a world with taxes, there is a small discrepancy between the deflated WACC WACCDef and the real wacc. This is due to the (1-T) term that is in the standard expression for the WACC applied to the Free Cash Flow (FCF). We compare different approaches for valuing nominal and real cash flows with...

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...

Discounting enables to express future monetary or socio-economic effects in terms of present values when inter-temporal decisions are to be taken. In the context of the cost-benefit analysis, this allows for directly comparing net benefits expressed in terms of their net present values, and,...

The opportunity cost of capital describes how invested resources would appreciate in value over time. Yet, currently, no consensus exists among economists as to how to account for this issue in a cost–benefit analysis, because disagreements are wrapped up in a broader, seemingly intractable,...

For investing in profitable ventures, the firms intend to recover the investment made in them. Thus, the determination of the respective cost of capital of a venture can provide a base for making decisions on whether to accept the project profitably. In this context, this paper provides some...

This paper shows that the notion of rate of return is best understood through the lens of the average-internal-rate-of-return (AIRR) model, first introduced in Magni (2010a). It is an NPV-consistent approach based on a coherent definition of rate of return and on the notion of Chisini mean, it...
