Why should the internal rate of return $($IRR$)$ not be used as the decision technique for projects with non$-$normal cash flows?

IRR can be relied upon for projects with either normal or non$-$normal cash flows.

IRR is unnecessary as all non$-$normal cash flow projects should be rejected.

Non$-$normal cash flows produce multiple IRRs so the accept$/$reject decision is questionable.

The IRR decision rule will always indicate an incorrect decision for projects with non$-$normal cash flows.
