12.5 A Project’s Cost of Capital
Calculating the project cost of capital can be done using all-equity comparable firms (Example 12.4)
or by using levered firms and removing the effects of leverage to arrive at the asset beta. The
12.6 Project Risk Characteristics and Financing
This section of the chapter discusses the differences in market risk across projects within a firm due to
12.7 Final Thoughts on Using the CAPM
The CAPM uses several assumptions and approximations. This section discusses its reliability. The
authors offer several thoughts on this. First, the types of approximations used to estimate cost of
capital are the same as those used to estimate cash flows but have far less impact on project value
than errors in the estimates used for cash flows. Second, the CAPM is practical, straightforward, and
Chapter 12 Appendix: Practical Considerations When Forecasting Beta
The Appendix discusses some practical issues about beta calculation, such as choosing a market
proxy and the time interval to use for estimation. It introduces a common method for adjusting beta,
as well as discussing treatment of outliers. Finally, the authors discuss the concept that firm
conditions and betas may change over time.
