Differential Analysis Report for Machine Replacement Lone Wolf Technologies Inc. assembles circuit boards by using a manually operated machine to insert electronic components. The original cost of the machine is $57,000, the accumulated depreciation is $22,800, its remaining useful life is five years, and its residual value is zero. A proposal was made to replace the present manufacturing procedure with a fully automatic machine that will cost $107,500. The automatic machine has an estimated useful life of five years and no significant residual value. For use in evaluating the proposal, the accountant accumulated the following annual data on current and proposed operations: Current Proposed Operations Operations 180,700 $180,700 $61,600 14,300 6,800 4,700 42,800 $130,200 Sales Direct materials Direct labor Power and maintenance Taxes, insurance, etc Selling and administrative expenses Total expenses $61,600 42,800 4,000 1,400 42,800 $152,600 a. Prepare a differential analysis report for the proposal to replace the machine. Include in the analysis both the net differential change in costs anticipated over the five years and the net annual differential change in costs anticipated LONE WOLF TECHNOLOGIES Replace Machine Differential Analysis Report Annual costs and expenses present machine Annual costs and expenses-new machine Number of years applicable Cost of new machine Annual net differential decrease in costs and expenses-new machine b. Based only on the data presented, should the proposal be accepted
