This document outlines capital budgeting concepts including projects, investment criteria, net present value (NPV) vs. internal rate of return (IRR). It defines projects and investment criteria like payback period, NPV, and IRR. NPV is the preferred method as it measures total discounted cash flows. While IRR and NPV typically agree for independent projects, they can differ for mutually exclusive projects due to reinvestment assumptions. The document also discusses sources of NPV and relevant cash flows to consider in capital budgeting analysis.
