A 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?
Using 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. The operating cost of the asset in year 1 is expected to be $30,000, and it will increase by $5,000 each year through year 4.

- 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%.arrow_forwardAtlantic 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.

- A 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. The projected resale values and operating and maintenance costs for the challenger and the defender are shown in the accompanying table on a year-by-year basis. The before-tax MARR is 15%.

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.

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?arrow_forward
- 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_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_forwardA boiler was bought for P1,500,000 cost of installation and shipping amounted to P200,000. The estimated salvage value after 20 years is 10% of the unit cost. Twelve years later the boiler will be rehabilitated at a cost of P300,000. Salvage value and economic life were expected to increase by P50,000 and 5 years respectively.

This machine is being depreciated on a straight line basis towards a K5000 salvage value, and it has six years of remaining life. Its current book value is K26000, and it can be sold at K30000 at this point. BTC is offered a replacement machine which has a cost of K80000, an estimated useful life of six years, and an estimated salvage value of K8000. The replacement machine would permit an output expansion, so that sales would rise by K10 000 per year, even so, the new machine with much greater efficiency would still cause operating expenses to decline by K15000 per year. The new machine would require that inventories be increased by K20000 and accounts payable would simultaneously increase by K5000. BTC’s effective tax rate is 46% and its cost of capital is 15%.
