The document discusses the profitability index, which is an investment appraisal technique that calculates the present value of future cash flows of a project divided by the initial investment. It provides the formula and explains that the profitability index is a modification of the net present value method and is a relative measure rather than an absolute one. Projects should be accepted if the profitability index is above 1 and rejected if below 1. An example calculates the profitability index of 1.3 for a project with a $65M present value of cash flows and $50M initial investment.
