Projects A and B both have normal cash flows. In other words, there is an up-front cost followed over time by a series of positive cash flows. Both projects have the same risk and a WACC equal to 10 percent. However, Project A has a higher internal rate of return than Project B. Assume that changes in the WACC have no effect on the projects’ cash flow levels. If Projects A and B have the same NPV at the current WACC, Project B would have a higher NPV if the WACC of both projects was lower.（ ）
