7. Understanding the NPV profile If projects are mutually exclusive, only one project can be chosen. The internal rate of return (IRR) and the net present value (NPV) methods will not always choose the same project. If the crossover rate on the NPV profile is below the horizontal axis, the methods will agree. Projects W and X are mutually exclusive projects. Their cash flows and NPV profiles are shown as follows. Year 0 Project W -$1,000 $200 $350 $400 $600 Project X $1,500 $350 $500 $600 $750 2 3 4 Project X NPV (Dollars) Project W O 2 4 6 8 10 12 14 COST OF CAPITAL (Percent) 16 18 20 If the required rate of return for each project is 6%, do the NPV and IRR methods agree or conflict? O The methods conflict. O The methods agree. A key to resolving this conflict is the assumed reinvestment rate. The NPV calculation implicitly assumes that intermediate cash flows are reinvested at the , and the IRR calculation assumes that the rate at which cash flows can be reinvested is the As a result, when evaluating mutually exclusive projects, the is usually the better decision criterion
