An analyst evaluates a project and finds that the discount rate at which the net present value of all its cash flows equals zero is higher than the required rate of return. Based on this alone, the analyst should:
Correct answer: A. The discount rate that drives net present value (NPV) to zero is the internal rate of return (IRR). When IRR exceeds the required rate of return, the project is expected to add value and is generally accepted.
Why not the others?
- B (reject on a positive IRR): A positive IRR above the hurdle rate is favorable, not a warning sign.
- C (NPV always negative): NPV is only negative when the required return is above the IRR. Here the IRR is higher, so at the required rate NPV is positive.
- D (need payback period): The IRR-versus-hurdle-rate comparison is a complete accept/reject signal on its own; payback is a separate, less rigorous measure.
Time value of money underlies the whole analytical section. The exam expects you to recognize that IRR is the rate where NPV equals zero and to apply the accept-if-IRR-exceeds-the-hurdle decision rule.
