Understand the concept of Internal Rate of Return (IRR): IRR is the discount rate at which the net present value (NPV) of a project becomes zero. It is used to evaluate the profitability of investments.
Identify the limitation of IRR: One key limitation is that IRR assumes that all interim cash flows generated by the project are reinvested at the IRR rate, which may not be realistic in practice.
Clarify why this assumption is problematic: In real-world scenarios, reinvestment rates may differ from the IRR, and this can lead to inaccurate projections of the project's profitability.
Compare IRR with other methods: For example, the NPV method assumes reinvestment at the firm's cost of capital, which is often more realistic. This highlights why IRR's reinvestment assumption can be a limitation.
Conclude the analysis: Recognize that while IRR is a useful tool for evaluating projects, its assumptions about reinvestment rates should be carefully considered, especially when comparing mutually exclusive projects or projects with varying cash flow patterns.
