Question
6.3 The Payback Rule
Use the following information to answer the question(s) below.
Rearden Metals is considering opening a strip mining operation to provide some of the raw materials needed in producing Rearden metal. The initial purchase of the land and the associated costs of opening up mining operations will cost $100 million today. The mine is expected to generate $16 million worth of ore per year for the next 12 years.

B) 6.00 years
C) 6.25 years
D) 6.50 years
2) Which of the following statements is false?
A) It is possible that an IRR does not exist for an investment opportunity.
B) If the payback period is less than a pre-specified length of time you accept the project.
C) The internal rate of return (IRR) investment rule is based upon the notion that if the return on other alternatives is greater than the return on the investment opportunity you should undertake the investment opportunity.
D) It is possible that there is no discount rate that will set the NPV equal to zero.
3) Which of the following statements is false?
A) The payback investment rule is based on the notion that an opportunity that pays back its initial investments quickly is a good idea.

D) In general, there can be as many IRRs as the number of times the project’s cash flows change sign over time.
4) Which of the following statements is false?

B) There is no easy fix for the IRR rule when there are multiple IRRs.
C) The payback rule is primarily used because of its simplicity.
D) No investment rule that ignores the set of alternative investment alternatives can be optimal.
5) Which of the following statements is false?
A) The payback rule is useful in cases where the cost of making an incorrect decision might not be large enough to justify the time required for calculating the NPV.
B) The payback rule is reliable because it considers the time value of money and depends on the cost of capital.
C) For most investment opportunities expenses occur initially and cash is received later.

D) Problems can arise using the IRR method when the mutually exclusive investments have differences in scale.
:

B) Picking one project over another simply because it has a larger IRR can lead to mistakes.
