Projects A and B each have an initial cost of $5,000, followed by a series of positive cash inflows. Project A has total undiscounted cash inflows of $12,000, while B has total undiscounted cash inflows of $10,000. Further, at a discount rate of 10 percent, the two projects have identical NPVs. Which project's NPV will be more sensitive to changes in the discount rate? Project A. Project B. Both projects are equally sensitive to changes in the discount rate since their NPV's are equal at all costs of capital. Neither project is sensitive to changes in the discount rate, since both have NPV profiles which are horizontal. The solution cannot be determined unless the timing of the cash flows is known
