Make-or-Buy, Traditional Analysis

Morrill Company produces two different types of gauges: a density gauge and a thickness gauge. The segmented income statement for a typical quarter follows.

	Density Gauge		Thickness Gauge		Total
Sales	$	157,500	$	84,000	$	241,500
Less variable expenses		84,000		48,300		132,300
Contribution margin	$	73,500	$	35,700	$	109,200
Less direct fixed expenses*		21,000		39,900		60,900
Segment margin	$	52,500	$	(4,200)	$	48,300
Less common fixed expenses						31,500
Operating income					$	16,800
* Includes depreciation.

The density gauge uses a subassembly that is purchased from an external supplier for $25 per unit. Each quarter, 2,100 subassemblies are purchased. All units produced are sold, and there are no ending inventories of subassemblies. Morrill is considering making the subassembly rather than buying it. Unit-level variable manufacturing costs are as follows:

Direct materials	$2
Direct labor	3
Variable overhead	2

No significant non-unit-level costs are incurred.

Morrill is considering two alternatives to supply the productive capacity for the subassembly.

1. Lease the needed space and equipment at a cost of $28,350 per quarter for the space and $10,500 per quarter for a supervisor. There are no other fixed expenses.
2. Drop the thickness gauge. The equipment could be adapted with virtually no cost and the existing space utilized to produce the subassembly. The direct fixed expenses, including supervision, would be $39,900, $8,400 of which is depreciation on equipment. If the thickness gauge is dropped, sales of the density gauge will not be affected.

Required:

1. Should Morrill Company make or buy the subassembly? Make the subassembly

If it makes the subassembly, which alternative should be chosen? Drop the thickness gauge
