Question
Garrett Boone, Farish Enterprises’ vice president of operations, needs to replace an automatic lathe on the production line. The model he is considering has a sales price of $289,225 and will last for 9 years. It will have no salvage value at the end of its useful life. Garrett estimates the new lathe will reduce raw materials scrap by $39,500 per year. He also believes the lathe will reduce energy costs by $26,250 per year. If he purchases the new lathe, he will be able to sell the old lathe for $6,303. Click here to view the factor table. (a) Calculate the lathe’s internal rate of return If Farish Enterprises uses a 15% hurdle rate, should Garrett purchase the lathe?
Explanation / Answer
Cash flow at 0 period = Purchase Price of New Lathe - Sale Price of Old Lathe
= 289225 - 6303
= $282922
Cash flow per year = Savings in material srcap + Savings in energy costs
= 39500 + 26250
= $65750
NPV @ 15% = Present Value of Cash inflows - Present Value of Cash outflows
= [65750 x 4.772] - 282922
= $30837
NPV @ 20% = Present Value of Cash inflows - Present Value of Cash outflows
= [65750 x 4.031] - 282922
= -$17884
Internal Rate of Return = Lower rate + [Lower rate NPV / (Lower rate NPV - Higher rate NPV) ] x Difference in rates
= 15 + [30837 / (30837+17884)] x 5
= 18.16%
If Farish Enterprises uses a 15% hurdle rate, Garrett should purchase the lathe as the NPV at 15% is positive.
