By failing to index the cash flows of projects in her NPV analysis, while at the same time including an adjustment for inflation into the discount rate, this analyst has biased the NPV calculation downward. This is because the cash inflows are being understated by the inflation-adjusted discounting. This phenomenon will skew the NPV figure downward. Remember that while the Internal Rate of Return calculation does not specify an explicit discount rate, rather calculates the discount rate that equates the cash inflows of a project with its cash outflows, the fact remains that the cash flows in the calculation have not been indexed for the effects of positive inflation. What has happened here is that cash flows have been understated, and this will bias the IRR calculation downward.
