The following example will demonstrate the

14、 absurdity of this statement.The McGraw-Hill Companies, Inc.,20016- 16Irwin/McGraw-HillPayback MethodExampleThe three project below are available.

17、rojects, the decision rule is simple. Calculate the NPV of each project, and, from those options that have a positive NPV, choose the one whose NPV is highest.The McGraw-Hill Companies, Inc.,20016- 19Irwin/McGraw-HillMutually Exclusive ProjectsExampleSelect one of the two following projects, based o

19、 McGraw-Hill Companies, Inc.,20016- 21Irwin/McGraw-HillInvestment TimingSometimes you have the ability to defer an investment and select a time that is more ideal at which to make the investment decision. A common example involves a tree farm. You may defer the harvesting of trees. By doing so, you

20、defer the receipt of the cash flow, yet increase the cash flow.The McGraw-Hill Companies, Inc.,20016- 22Irwin/McGraw-HillInvestment TimingExampleYou may purchase a computer anytime within the next five years. While the computer will save your company money, the cost of computers continues to decline

21、.

The following two projects illustrate that problem.Pitfall 2 - Lending

28、or Borrowing? With some cash flows (as noted below) the NPV of the project increases s the discount rate increases. This is contrary to the normal relationship between NPV and discount rates. Pitfall 3 - Multiple Rates of Return Certain cash flows can generate NPV=0 at two different discount rates.
