3) Multiple IRRs and MIRR. A mining company is deciding whether to open a strip mine, which costs $2 million. Net cash inflows of $13 million would occur at the end of Year 1 . The land must be retumed to its natural state at a cost of $12 million, payable at the end of Year 2. a) Plot the project's NPV profile. b) Should the project be accepted if WACC =10% ? If WACC =20% ? Explain your reasoning. c) Can you think of some other capital budgeting situation in which negative cash flows during or at the end of the project's life might lead to multiple IRRs? d) What is the project's MIRR at WACC =10% ? At WACC =20% ? Does MIRR lead to the same accept/reject decision for this project as the NPV method? Does the MIRR method always lead to the same accept /reject decision as NPV?
