A PRO assessment was performed on the four identified risks. For each of the risks the estimated cost of mitigating the risk (investment) was determined; the enterprise net present value (NPV) protected was calculated given the investment was made; and, the investment productivity (a.k.a return on investment) for each investment was calculated. The following table summarizes this information.
