The first edition of this text has a tendency to get too theoretical with betas and CAPM as they apply to private companies, make too many distinctions between individual and personal required rates of return without a discussion of any empirical data to back up the opinions, not explain the implications of the SML theory to private investments that well, not fully explain the theory and computations behind the models they use or why they use escalating discount rates in the models. To try to understand the models, you have to go to the web site and dissect the Excel spreadsheet. I have the impression the authors bring no practical experience to the text, only the attempt to force complicated corporate financial theory into the realm of privately held business.
As a business appraiser, I found most of the quantitative theoretical information useless and its application to privately held businesses tenuous, at best. Alternative theories and approaches were not really discussed. The concepts of expected value and simulation have some real good application possibilities, but not much time was spent on how to do it in a way usable for small entities with limited budgets and a staff with basically no statistical background. I feel that the authors' agenda was to impress the readers with what they know (or think they know), without regard to conveying their ideas in an easily understood, supportable and workable format. I found chapters 8-11 to be especially frustrating. To top it all off, there are also errors in the answers to the end of chapter questions.
On the positive side, the book was well organized and there were references to studies, papers and other texts that make further reading and investigation into the topics easier.
