Equation solution: (Note that if the cash inflows are summed, they exactly equal the cash
outflow at time zero.) NPVr = 0% = 0 = −$17,600 + $3,400 + $4,840 + $3,280 + $2,440 +
$3,640. This implies an IRR of 0.0% Financial calculator solution: Inputs: CF0 = −17,600;
CF1 = 3,400; CF2 = 4,840; CF3 = 3,280; CF4 = 2,440; CF5 = 3,640. Output: IRR = 0.0%.

IRR of Replacement Project
85. California Mining is evaluating the introduction of a new ore production process. Two alternatives are available.
Production Process A has an initial cost of $25,000, a 4-year life, and a $5,000 net salvage value, and the use of Process A
will increase net cash flow by $13,000 per year for each of the 4 years that the equipment is in use. Production Process B
also requires an initial investment of $25,000, will also last 4 years, and its expected net salvage value is zero, but Process
B will increase net cash flow by $15,247 per year. Management believes that a risk-adjusted discount rate of 12 percent
should be used for Process A. If California Mining is to be indifferent between the two processes, what risk-adjusted
discount rate must be used to evaluate B?
Financial calculator solution: Process A: Inputs: CF0 = −25,000; CF1 = 13,000; Nj = 3;
CF2 = 18,000; I = 12. Output: NPVA = 17,663.13. Process B: Inputs: CF0 = −42,663.13;
CF1 = 15,247; Nj = 4. Output: IRR = 16.0% = r.
