If mutually exclusive projects with normal cash flows are being analyzed, the net present value (NPV) and internal rate of return (IRR) methods ________ agree. Projects Y and Z are mutually exclusive projects. Their cash flows and NPV' profiles are shown as follows. If the weighted average cost of capital (WACC) for each project is 34%, do the NPV and IRR methods agree or conflict? The methods agree. The methods conflict. 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
