Overton Electronics manufactures two large-screen television models:
the Royale which sells for $1,600, and a new model, the Majestic, which
sells for $1,300. The production cost computed per unit under
traditional costing for each model in 2011 was as follows.
Traditional Costing Royale Majestic
Direct
materials
$700 $420
Direct labor ($20 per hour) 120 100
Manufacturing overhead ($38 per DLH) 228 190
Total per unit cost $1,048 $710
In 2011, Overton manufactured 25,000 units of the Royale and
10,000 units of the Majestic. The overhead rate of $38 per direct labor
hour was determined by dividing total expected manufacturing overhead of
$7,600,000 by the total direct labor hours (200,000) for the two
models.
Under traditional costing, the gross profit on the models was:
Royale $552 or ($1,600 - $1,048), and Majestic $590 or ($1,300 - $710).
Because of this difference, management is considering phasing out the
Royale model and increasing the production of the Majestic model.
Before finalizing its decision, management asks Overton\'s
controller to prepare an analysis using activity-based costing (ABC).
The controller accumulates the following information about overhead for
the year ended December 31, 2011.

Requirement:
- Assign the total 2011 manufacturing overhead costs to the two products using activity-based costing (ABC).
- What was the cost per unit and gross profit of each model using ABC costing?
