In my opinion, this is the most important chapter in the book. The information is critical to the success of business undertakings and is an important part of the study of Finance as well as Accounting. The book discusses a number of capital budgeting methods, net present value, internal rate of return, payback period, profitability index, and the simple rate of return. Why are so many used? They share similarities and differences - like what? Is one better than the others? Which one? Please explain why? Are there other methods not discussed?
