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?
A factory manager bought a rare machine for $10 million. of the machine The sales value at the end of the first year will be $3 million and the machine will be sold by antique dealers. It is estimated to be valued at $500,000 due to the Initial cost of maintenance Expected to be $300,000 in 3 years and double each year thereafter. In this way, the maintenance cost of the 4th year is $600,000, the maintenance cost of the 5th year is $1,200,000, etc. will be. Calculate the economic life of this machine based on the Minimum Attractive Efficiency Ratio of 15%.
The AW values for retaining a presently owned machine for additional years are shown in the table. Note that the values represent the AW amount for each of the n years that the asset is kept, i.e., if it is kept 5 more years, the annual worth is $−95,000 for each of the 5 years. Assume that future costs remain as estimated for the replacement study and that used machines like the one presently owned will always be available.

The company believes that a realistic MARR would be 10%. Taxes, insurance, and storage should amount to an additional 8%, which results in an overall cost of money of 10 + 8, or 18%.

- A building supplies distributor purchased a gasoline-powered forklift truck 4 years ago for $8,000. 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.
