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.
