The Ajax Corporation has an overhead crane that has an estimated remaining life of 10 years. The crane can be sold now for $8,000. If the crane is kept in service, it must be overhauled immediately at a cost of $5,000. Operating and maintenance costs will be $3,000 per year after the crane is overhauled. The overhauled crane will have zero MV at the end of the 8-year study period. A new crane will cost $20,000, will last for 8 years, and will have a $4,000 MV at that time. Operating and maintenance costs are $1,000 per year for the new crane. The company uses a before-tax interest rate of 10% per year in evaluating investment alternatives. Should the company replace the old crane?

- A4-5 A production facility is currently utilizing carbon steel tubing. The current process will require the injection of chemicals to control tubing corrosion due to high temperatures, pressures, and corrosive chlorides in the transported product. It is proposed to replace the car- bon steel that cost $12 per foot with an installation cost of $125,000 last year, with a chrome stainless steel tubing that would cost $68 per foot today (time zero). 20,000 feet of tubing would be required and installation costs are estimated to total $500,000 (also at time zero). Annual cost savings in chemicals, labor, and chemical injection equip- ment are projected to be $550,000 in year one. The year one savings would escalate at an annually compounded rate of 7% per year beginning in year 2. For simplicity, use a 6-year evaluation life with a salvage value of zero at the end of year 6.

At that time, the estimated useful life was 8 years with a salvage value of $800 at the end of this time. The truck can now be sold for $2,500. For this truck, average annual O&M expenses for year j have been Cj = $2, 000 + $400(j − 1) Now the distributor is considering the purchase of a smaller battery-powered truck for $6,500. The estimated life is 10 years, with the salvage value decreasing by $600 each year. Average annual O&M expenses are expected to be $1,200.
