Question

Make-or-Buy Decision

Fremont Computer Company has been purchasing carrying cases for its portable computers at a purchase price of $60 per unit. The company, which is currently operating below full capacity, charges factory overhead to production at the rate of 42% of direct labor cost. The unit costs to produce comparable carrying cases are expected to be as follows:

Direct materials	$28
Direct labor	19
Factory overhead (42% of direct labor)	7.98
Total cost per unit	$54.98

If Fremont Computer Company manufactures the carrying cases, fixed factory overhead costs will not increase and variable factory overhead costs associated with the cases are expected to be 13% of the direct labor costs.

a. Prepare a differential analysis dated September 30 to determine whether the company should make (Alternative 1) or buy (Alternative 2) the carrying case. If required, round your answers to two decimal places. If an amount is zero, enter "0". Use a minus sign to indicate a loss.

Differential Analysis
Make Carrying Case (Alt. 1) or Buy Carrying Case (Alt. 2)

b. Assuming there were no better alternative uses for the spare capacity, it would   to manufacture the carrying cases. Fixed factory overhead is   to this decision.

Answer 1

Solution a:

Differential Analysis - Making Carrying Case (alt 1) or Buying Carrying Case (Alt2)
Particulars	Making Carrying Case (Alt 1)	Buying Carrying Case (Alt 2)	Differential Effect on Income (Alternative 2)
Sales price	$0.00	$0.00	$0.00
Costs:
Purchase Price	$0.00	$60.00	$60.00
Direct material per unit	$28.00	$0.00	-$28.00
Direct Labor per unit	$19.00	$0.00	-$19.00
Variable overhead per unit ($19*13%)	$2.47	$0.00	-$2.47
Fixed factory overhead per unit [$19*(42%-13%)]	$5.51	$5.51	$0.00
Income (Loss)	-$54.98	-$65.51	-$10.53

Solution b:

Assuming there were no better alternative uses for the spare capacity, it would be advisable to manufacture the carrying cases. Fixed overhead is Irrelevant to this decision.
