Acme-Denver Corporation is considering the replacement of an old, relatively inefficient surface-grinder machine that was purchased seven years ago at a cost of $12,000. The machine had an original expected life of 10 years and a zero estimated salvage value at the end of that period. The current market value of the machine is $2,000. The divisional manager reports that a new machine can be bought and installed for $14,000. Over its five-year life, this machine will expand sales from $10,000 to $12,500 a year and, furthermore, will reduce labor and raw materials usage sufficiently to cut annual operating costs from $7,000 to $5,000. The new machine has an estimated salvage value of $4,000 at the end of its five-year life. The firm's MARR is 12%.(a) Should the new machine be purchased now?(b) What current market value of the new machine would make the two options equal?
Atlantic Control Company purchased a machine two years ago at a cost of $70,000. At that time, the machine’s expected economic life was six years and its salvage value at the end of its life was estimated to be $10,000. It is being depreciated using the straight line method so that its book value at the end of six years is $10,000. In four years, however, the old machine will have a market value of $0. A new machine can be purchased for $80,000, including shipping and installation costs. The new machine has an economic life estimated to be four years. Three-year MACRS depreciation will be used. During its four-year life, the new machine will reduce cash operating expenses by $20,000 per year. Sales are not expected to change. But the new machine will require net working capital to be increased by $4,000. At the end of its useful life, the machine is estimated to have a market value of $2,500. What is the NPV of this project? Should Atlantic replace the old machine (assuming a…
An auto-part manufacturer is faced with the prospect of replacing its old robot, which has been used in stamping operation for 10 years. This particular robot was installed at a cost of $100,000 and was assumed to have a 15-year life with no appreciable salvage value. The current annual operating costs are $20,000 for this old robot, and these costs are presumed to be the same for the rest of its life. A sales representative from Advanced Robotic Systems is trying to sell this company a new-highly efficient robot. The new system would require an investment of $200,000 for installation. The economic life of this new robot is estimated to be IO years with a salvage value of $18,000, and the robot will reduce annual operating costs to $5,000. No detailed agreement has been made with the sales representative about the disposal of the old robot. Determine therange of resale values associated with the old system that would justify installation of the new system at a MARR of 14%.

- Gordon Inc. has a number of copiers that were bought four years ago for $20,000. Currently maintenance costs $2,000 a year, but the maintenance agreement expires at the end of two years and thereafter the annual maintenance charge will rise to $8,000. The machines have a current resale value of $8,000, but at the end of year 2 their value will have fallen to $3,500. By the end of year 6 the machines will be valueless and would be scrapped. Gordon is considering replacing the copiers with new machines that would do essentially the same job. These machines cost $25,000, and the company can take out an eight-year maintenance contract for $1,000 a year. The machines have no value by the end of the eight years and would be scrapped. Both machines are depreciated by using seven-year MACRS, and the tax rate is 35 percent. Assume for simplicity that the inflation rate is zero. The real cost of capital is 7 percent. When should Gordon replace its copiers, now, the end of year 2, or the end of…arrow_forwardA high-speed electronic assembly machine was purchased two years ago for $50,000. At the present time, it can be sold for $25,000 and replaced by a newer model having a purchase price of $42,500; or it can be kept in service for a maximum of one more year. The new assembly machine, if purchased, has a useful life of not more than two years.

It was assumed that the process would have a 20-year life with a zero salvage value. The current market value of the equipment, however, is $60,000, and the initial estimate of its economic life is still good. The annual operating costs associated with this process are $18,000. A sales representative from U.S. Instrument Company is trying to sell a new chemical compound-making process to the company. This new process will cost $200,000 have a service life of IO years with a salvage value of $20,000, and reduce annual operating costs to $4,000.

- A radiology clinic is considering buying a new $700,000 x-ray machine, which will have no salvage value after installation because the cost of removal will be approximately equal to its sales value. Maintenance is estimated at $24,000 per year as long as the machine is owned. After 10 years the x-ray source will be depleted and the machine must be scrapped. Which of the following represents the most economic life of this x-ray machine? Solve a.One year, because it will have no salvage after installation b. Five years, because the maintenance costs are constant c. Ten years, because maintenance costs don't increase d.

The crane can now be sold for $8,000. If it stays in service it should get a major repair costing $4,000. After the fix, you will have operating and maintenance costs of $3,000 per year. Once repaired, the crane will have a market value of zero at the end of the 10-year study period. A new crane would cost $18,000, last 10 years, and have a market value of $4,000 at the end of that term. The operating and maintenance expenses for this new machine would be $1,000 per year. To evaluate its investment alternatives, the company uses an interest rate of 10% per year before taxes. Should the company replace the old crane?arrow_forward
- Market Top Investors, Incorporated, is considering the purchase of a $345, 000 computer with an economic life of five years. The computer will be fully depreciated over five years using the straight - line method, at which time it will be worth $78, 000. The computer will replace two office employees whose combined annual salaries are $89, 000. The machine will also immediately lower the firm's required net working capital by $78, 000. This amount of net working capital will need to be replaced once the machine is sold. The corporate tax rate is 23 percent. The appropriate discount rate is 11 percent. Calculate the NPV of this projectarrow_forwardA present asset (defender) has a current market value of $85,000 (year 0 dollars). Estimated market values at the end of the next three years, expressed in year 0 dollars, are MV1= $73,000, MV2 = $60,000, MV3 = $40,000. The annual expenses (expressed in year 0 dollars) are $15,000 and are expected to increase at 4.5% per year. The before-tax nominal MARR is 15% per year. The best challenger has an economic life of five years and its associated EUAC is $39,100. Market values are expected to increase at the rate of inflation which is 3% per year. Based on this information and a before-tax analysis, what are the marginal costs of the defender each year and when should you plan to replace the defender with the challenger?arrow_forwardA machine costs $19,310 and is expected to have a scrap value of $2,991 whenever it is retired. Operating and Maintenance costs are $1,047 for the first year and expected to increase by $1,751 thereafter. If the MARR is 12%, determine the minimum equivalent uniform annual cost associated with the optimal economic life of the machine. The service life of this machine is 5 years.
