Question

1. Make-or-Buy Decision

Companion Computer Company has been purchasing carrying cases for its portable computers at a purchase price of $61 per unit. The company, which is currently operating below full capacity, charges factory overhead to production at the rate of 39% of direct labor cost. The fully absorbed unit costs to produce comparable carrying cases are expected to be as follows:

Direct materials $29
Direct labor 20
Factory overhead (39% of direct labor) 7.8
Total cost per unit $56.8

If Companion 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 15% of the direct labor costs.

2. Machine Replacement Decision

A company is considering replacing an old piece of machinery, which cost $599,500 and has $349,400 of accumulated depreciation to date, with a new machine that has a purchase price of $483,600. The old machine could be sold for $63,000. The annual variable production costs associated with the old machine are estimated to be $157,300 per year for eight years. The annual variable production costs for the new machine are estimated to be $102,300 per year for eight years.

 

a. Prepare a differential analysis dated February 24 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". For those boxes in which you must enter subtracted or negative numbers use
a minus sign.

Expert Solution
Step 1

The decision of make or buy is defined as the act of using the cost- benefit in order to make the strategic decision among manufacturing the product in house or to buy the product from the external supplier. This situation arises when the producing company face problems with present suppliers and diminishing capacity.

Direct Labor per unit $20 - $20
Variable factory overhead  per unit $3 - $3
Fixed factory overhead per unit $4.8 $4.8 -
Income (Loss) $56.8 $65.8 -$9

 

Working Note:

1. Computing variable factory overhead as:

Variable factory overhead = 15% ×Direct labor=15% ×$20=$3

 

2. Computing fixed factory overhead per unit as:

Fixed factory overhead per unit = Factory overhead - Variable factory overhead per unit=$7.8 - $3=$4.8
