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 $58,800, the accumulated depreciation is $23,500, 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 $122,300. 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	$186,400		$186,400
Direct materials	$63,500		$63,500
Direct labor	44,100
Power and maintenance	4,100		21,800
Taxes, insurance, etc.	1,500		4,900
Selling and administrative expenses	44,100		44,100
Total expenses	$157,300		$134,300

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".
