what is your input on this? Non-normal cash flows are shown in the patterns seen in typical projects. This can include uneven cash flows, changes in directions, and irregular timing of cash flows. Net present value, modified internal rate of return, and Profitability index are the three options that work for non-normal cash flows. A firm's best option for capital budgeting techniques would be to use net present value and modified internal rate of return. NPV considers timing of the cash flows, and MIRR provides more accurate rate or return for projects. If only one technique is allowed, I would choose net present value. This is considered the most reliable because it take into account the timing of all cash flows
