Answer:
II, III, and IV only
Explanation:
The first statement is wrong. IRR is the rate that causes the net present value of a projects cash-flows to exactly equal zero, and therefore a project with a required rate of return higher than the IRR would mean that the cash-flows have to be discounted by a higher rate, which would yield a negative net present value. Such a project would reduce shareholder wealth and should be rejected. The other 3 statements are correct.
