Trainor Machines LLC makes specialized machine parts for a number of clients, all of whom are major manufacturers. Trainor is considering replacing one of the special machines used in the production of a specific product; this machine was purchased eight years ago for $619,500 and has seven years of useful life remaining. The new machine, costing $386,000, is expected to have a useful life equal to the remaining useful life of the current machine and a zero disposal value. Trainor incurs annual operating costs equal to $76,000 with the existing equipment, but the new equipment is expected to result in operating costs equal to $38,000. Trainor expects to incur additional maintenance expense on the existing machine over the remainder of its seven-year life as follows: $6,000 per year in the first three years, $8,000 per year in years 4 and 5, and $10,000 per year in years 6 and 7. Despite the significant reduction in annual operating costs, as well as the increase in maintenance costs, the controller is hesitant because the machine is a specialized piece of equipment and, due to the limited second-hand market for such a machine, the current one could only be sold for 50% of its current book value of $289,100, resulting in a loss on disposal of $144.550.
