The presentation discusses the profitability index (PI), which is a capital budgeting technique used to evaluate investment projects based on their profitability. The PI is calculated as the discounted cash inflows divided by the initial cash outflow. A PI greater than or equal to 1 indicates the project is profitable. The presentation provides an example calculation of the PI for a project with an initial investment of $200,000 and cash flows of $40,000, $30,000, $50,000 and $20,000 over 4 years with a 10% discount rate, resulting in a PI of 1.1235.
