Differential Analysis for Machine Replacement

Kim Kwon Digital Components Company assembles circuit boards by using a manually operated machine to insert electronic components. The original cost of the machine is $76,300, the accumulated depreciation is $30,500, its remaining useful life is five years, and its residual value is negligible. On May 4 of the current year, a proposal was made to replace the present manufacturing procedure with a fully automatic machine that has a purchase price of $158,700. 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 present and proposed operations:

	Present Operations		Proposed Operations
Sales	$241,900		$241,900
Direct materials	$82,400		$82,400
Direct labor	57,200
Power and maintenance	5,300		28,200
Taxes, insurance, etc.	1,900		6,300
Selling and administrative expenses	57,200		57,200
Total expenses	$204,000		$174,100

a. Prepare a differential analysis dated May 4 to determine whether to continue with the old machine (Alternative 1) or replace the old machine (Alternative 2). Prepare the analysis over the useful life of the new machine. If an amount is zero, enter "0". For those boxes in which you must enter subtracted or negative numbers use a minus sign.

Income (Loss)	$	$	$

b. Based only on the data presented, should the proposal be accepted?

c. Differences in capacity between the two alternatives is to consider before a final decision is made.
