ABSTRACT
The NPV is the present value (base year = 2000) of benefits less the PV of costs. Because costs are assumed to be incurred at the beginning of a period and benefits at the end, benefits are discounted one additional period than costs. Table 16 presents the PV of net attributable benefits. Subtracting the PV of costs from the PV of benefits yields an NPV between $39.75 million21 and $63.14 million22 (see Table 17).
