Question

Masse Corporation uses part G18 in one of its products.

The company's Accounting Department reports the following costs of producing the 17,100 units of the part that are needed every year:
Per Unit
Direct materials $4.30
Direct labor 5.00
Variable overhead 8.00
Supervisor's salary 8.70
Depreciation of special equipment 9.30
Allocated general overhead 6.30
An outside supplier has offered to make the part and sell it to the company for $32.00 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.
If the outside supplier's offer were accepted, only $23,100 of these allocated general overhead costs would be avoided.
In addition, the space used to produce part G18 could be used to make more of one of the company's other products, generating an additional segment margin of $33,000 per year for that product.
Required:
1. Calculate the effect on the company's total net operating income of buying part G18 from the supplier rather than continuing to make it inside the company.
2. Which alternative should the company choose?
Buy or Make

Answer 1

Masse Corporation

1. The effect on the company's total net operating income of buying part G18 from the supplier rather than continuing to make it inside the company is an additional cost of $47,100.

2. Masse Corporation should continue to produce the part in-house. The "Make" alternative is better.

Step-by-step explanation:

a) Data and Calculations:

Units of part G18 needed yearly = 17,100

Costs of production:

Direct materials $4.30

Direct labor 5.00

Variable overhead 8.00

Supervisor's salary 8.70

Total variable costs= $26 * 17,100 = $444,600

Avoidable general overhead cost = $23,100

Total avoidable costs = $467,100

Outside supplier's offered price for the part = $32 each

Total cost for the outside supply = $547,200 ($32 * 17,100)

Unavoidable fixed costs:

Depreciation of special equipment 9.30

Allocated general overhead 6.30 * 17,100 = $107,730

Unavoidable cost = $84,630 ($107,730 - $23,100)

b) The effect on the company's total net operating income of buying part G18 from the supplier rather than continuing to make it inside the company is an additional cost of $47,100 ($547,200 - $467,100 - $33,000).
