Melissa Ostwerk, the new controller of TurboDrives, Inc., has just returned from a seminar on the choice of the activity level in the predetermined overhead rate. Even though the subject did not sound exciting at first, she found that there were some important ideas presented that should get a hearing at her company. After returning from the seminar, she arranged a meeting with the production manager, Jan Kingman, and the assistant production manager, Lonny Chan.

Melissa: I ran across an idea that I wanted to check out with both of you. Its about the way we compute predetermined overhead rates.

Jan: Were all ears.

Melissa: We compute the predetermined overhead rate by dividing the estimated total factory overhead for the coming year, which is all a fixed cost, by the estimated total units produced for the coming year.

Lonny: Weve been doing that as long as Ive been with the company.

Jan: And it has been done that way at every other company Ive worked at, except at most places they divide by direct labor-hours.

Melissa: We use units because it is simpler and we basically make one product with minor variations. But, theres another way to do it. Instead of basing the overhead rate on the estimated total units produced for the coming year, we could base it on the total units produced at capacity.

Lonny: Oh, the Marketing Department will love that. It will drop the costs on all of our products. Theyll go wild over there cutting prices.

Melissa: That is a worry, but I wanted to talk to both of you first before going over to Marketing.

Jan: Arent you always going to have a lot of underapplied overhead?

Melissa: Thats correct, but let me show you how we would handle it. Heres an example based on our budget for next year.

Budgeted (estimated) production		70,000		units
Budgeted sales		70,000		units
Capacity		100,000		units
Selling price	$	60		per unit
Variable manufacturing cost	$	18		per unit
Total manufacturing overhead cost (all fixed)	$	1,400,000
Selling and administrative expenses (all fixed)	$	1,320,000
Beginning inventories	$	0

Traditional approach to computing the predetermined overhead rate:

Predetermined overhead rate	=	Estimated total manufacturing overhead cost
		Estimated total amount of the allocation base

	=	$1,400,000	= 20 per unit
		$70,000unit

Budgeted Income Statement
Revenue (70,000 units $60 per unit)					$	4,200,000
Cost of goods sold:
Variable manufacturing (70,000 units $18 per unit)	$	1,260,000
Manufacturing overhead applied (70,000 units $20 per unit)		1,400,000				2,660,000
Gross margin						1,540,000
Selling and administrative expenses						1,320,000
Net operating income					$	220,000

New approach to computing the predetermined overhead rate using capacity in the denominator:

Predetermined overhead rate	=	Estimated total manufacturing overhead cost at capacity
		Estimated total amount of the allocation base at capacity

	=	$1,400,000	= $14 per unit
		100,000 units

Budgeted Income Statement
Revenue (70,000 units $60 per unit)					$	4,200,000
Cost of goods sold:
Variable manufacturing (70,000 units $18 per unit)	$	1,260,000
Manufacturing overhead applied (70,000 units $14 per unit)		980,000				2,240,000
Gross margin						1,960,000
Cost of unused capacity [(100,000 units 70,000 units) $14 per unit]						420,000
Selling and administrative expenses						1,320,000
Net operating income					$	220,000

Jan: Whoa!! I dont think I like the looks of that Cost of unused capacity. If that thing shows up on the income statement, someone from headquarters is likely to come down here looking for some people to lay off.

Lonny: Im worried about something else, too. What happens when sales are not up to expectations? Can we pull the hat trick?

Melissa: Im sorry, I dont understand.

Jan: Lonnys talking about something that happens fairly regularly. When sales are down and profits look like they are going to be lower than the president told the owners they were going to be, the president comes down here and asks us to deliver some more profits.

Lonny: And we pull them out of our hat.

Jan: Yeah, we just increase production until we get the profits we want.

Melissa: I still dont understand. You mean you increase sales?

Jan: Nope, we increase production. Were the production managers, not the sales managers.

Melissa: I get it. Because you have produced more, the sales force has more units it can sell.

Jan: Nope, the marketing people dont do a thing. We just build inventories and that does the trick.

Required:

In all of the forthcoming questions, assume that the predetermined overhead rate under the traditional method is $20 per unit, and under the new method it is $14 per unit. Also, assume that under the traditional method any underapplied or overapplied overhead is taken directly to the income statement as an adjustment to Cost of Goods Sold.

1. Suppose actual production is 70,000 units. Compute the net operating incomes that would be realized under the traditional and new methods if actual sales are 65,000 units and everything else turns out as expected.

Traditional approach:

New approach:

2. How many units would have to be produced under each of the methods in order to realize the budgeted net operating income of $220,000 if actual sales are 65,000 units and everything else turns out as expected?

Actual number of units to be produced traditional approach and new approach?
