In evaluating projects with "non-normal cash flows" the Internal Rate of Return method will often produce multiple IRRs which leads to an incorrect accept/reject decision. Non-normal cash flows are defined as cash flows in which the sign changes more than once. Projects B and D involve cash outflows superimposed within the cash inflows, resulting in a sign change from positive to negative and negative to positive. In examining projects such as this, it is advisable to use either the NPV or MIRR methods. From observation alone, we can determine that project B and D are non-normal projects, and are thus likely to result in multiple IRR calculations. While projects A and C do involve periods of zero cash flow, this will not interfere with the IRR calculation to the extent of producing multiple IRRs.
