Question

Mcfarlain Corporation is presently making part U98 that is used in one of its products. A total of 20,000 units of this part are produced and used every year. The company's Accounting Department reports the following costs of producing the part at this level of activity:

	Per Unit
Direct materials	$	5.00
Direct labor	$	3.10
Variable overhead	$	1.20
Supervisor's salary	$	3.40
Depreciation of special equipment	$	3.40
Allocated general overhead	$	3.60

An outside supplier has offered to produce and sell the part to the company for $15.00 each. If this offer is accepted, the supervisor's salary and all of the variable costs, including direct labor, can be avoided. The special equipment used to make the part was purchased many years ago and has no salvage value or other use. The allocated general overhead represents fixed costs of the entire company, none of which would be avoided if the part were purchased instead of produced internally.

In addition to the facts given above, assume that the space used to produce part U98 could be used to make more of one of the company's other products, generating an additional segment margin of $38,100 per year for that product. What would be the financial advantage (disadvantage) of buying part U98 from the outside supplier and using the freed space to make more of the other product?

Multiple Choice

• $38,100

• ($7,900)

• ($23,900)

• ($100,100)

Answer 1

	Per unit		Total 20000 units
	Make	Buy	Make	Buy
Direct materials	5.00		100,000
Direct labor	3.10		62,000
Variable overhead	1.20		24,000
Supervisor's salary	3.40		68,000
Opportunity cost			38,100
Purchase cost		15.00		300,000
Total			292,100	300,000
Difference in favor of making = 292,100-300,000 =( $7,900)
Financial (disadvantage) $(7,900)

Hence correct option is (b) $(7,900)
