Explanation : For a project with normal cash flows, the NPV profile intersects the horizontal
axis at the point where the discount rate is equal to the IRR. The crossover rate
is the discount rate at which the NPVs of the projects are equal. While it is
possible that the crossover rate is equal to each project’s IRR, it is not a likely
event. The IRR for both projects being the firm’s WACC will only arise when
both projects have a NPV = 0.
