II. Learning Objectives
7.1 Define net present value, payback period, internal rate of return, profitability index, and
incremental IRR.
7.3 Given cash flows, compute the NPV, payback period, internal rate of return, and profitability
index for a given project, and compute the incremental IRR for a pair of projects.
7.5 Discuss the reasons IRR can give a flawed decision.
III. Chapter Overview
This chapter introduces techniques that firms use to evaluate investments and decide which projects
to pursue, including NPV, payback period, internal rate of return, profitability index, incremental
IRR, and EVA, with an emphasis on NPV. The chapter then covers choosing between projects when
they are mutually exclusive, and finally choosing between projects when there is a resource
constraint.
7.1 NPV and Stand-Alone Projects
The text emphasizes NPV as the only reliable way to make capital budgeting decisions. The internal
rate of return can provide a measure of the sensitivity of the NPV to changes in the opportunity cost
of capital. Because the IRR is the point at which NPV equals zero, it can be used to measure the
