Problems P10-15 Relevant cost analysis; book value Time allowed: 25 minutes Murl Plastics Ltd purchased a new machine one year ago at a cost of 60,000.

The new machine would slash annual operating costs by two-thirds, as shown in the comparative data below: Present machine Proposed new machine 90,000 5 years 14,000 18,000 Purchase cost new Estimated useful life new Annual operating costs Annual straight-line depreciation Remaining book value Salvage value now Salvage value in 5 years 60,000 6 years 42,000 10,000 50,000 10,000 0 0 In trying to decide whether to purchase the new machine, the MD has prepared the following analysis: Book value of the old machine Less salvage value Loss from disposal 50,000 10,000 40,000 'Even though the new machine looks good,' said the managing director, 'we can't get rid of the old one if it means taking a huge loss on it. We'll have to use it for at least a few more years."
