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?
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…

- A firm owns a drilling equipment that it is contemplating replacing. It is believed that P1,500,000 could be obtained for the old equipment if it were sold now, but it can be productively used for four more years at which time its market value will be zero. The equipment has an operating and maintenance of P600,000 per year. The firm can purchase a new machine, with the same functionality as the current machine, for P5,500,000. In four years the market value of the new machine is estimated to be P2,275,000. Annual operating and maintenance costs will be P1,850,000 per year. Should the old drilling equipment be replaced using a before-tax MARR of 15% and a study period of four years?arrow_forwardUsing the asset description and table below, find the economic service life (ESL) of the asset, assuming MARR = 8%. The company is committed to using the asset for the upcoming year, but is unsure about the following years. Today's market value is $70,000, and it will last another 4 years before failure. Each year, the after-tax market value decreases by $10,000.

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.

- 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.

The machine will cost $180,000. With additional transportation and installation costs of $5,000 and $10,000, respectively, the cost basis for depreciation purposes is $195,000. Its MV at the end of five years is estimated as $40,000. The IRS has assured you that this machine will fall under a three-year MACRS class life category. The justifications for this machine include $40,000 savings per year in labor and $30,000 savings per year in reduced materials.

- St. Francis Cooperative purchased a P45 000.00 — pump for its irrigation project. Setup and installation cost amounted to P5000.00. Using the SYD method, economic life and salvage value was initially estimated to be 12 years and P3800.00, respectively. Due to poor maintenance and continuous exposure to the elements, a re-evaluation after five years indicated that the remaining economic life is only four years, with a salvage value of P2500.00. Find the book value of the pump for the seventh year. (Ans. P7865.40)arrow_forward. A machine costs $ 10,000 and is expected to be scrapped for $ 1,500 in the moment he retires. Operating expenses for the first year are expected to be $ 3,500 and increasing by $ 400 as a result of the impairment; and operating income Estimated $ 20,000 If the MARR is 15%, determine the economic life of the machine.arrow_forwardA company is currently producing chemical compounds by a process installed 10 years ago at a cost of $100,000. It was assumed that the process would have a 20-year life with a zero salvage value.

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.

Compute the book value at the end of three years for tax purposes.arrow_forwardIt is desired to determine the resent economic Value of an old machine by considering of how it compares with the best modern machine that could replace it. The old machine is expected to require out of pocket cost of 85,000 each year for 4 years and then be scared for 5,000 residual value. The new machine requires an investment of 40,000 and would have out of the pocket costs of 79,000 a year for 8 years and the zero-salvage value. Invested capital should earn a minimum return of 15% before taxes. Determine the present value of an old machine.arrow_forward
