Traditional, Volume-Based Product-Costing System • Aerotech produces three complex printed circuit boards referred to as Mode I, Mode II, and Mode III. • The following information is obtained from company records:

Production: Units Runs

Mode I

Mode II

Mode III

10,000 1 run of 10,000 units

20,000 4 runs of 5,000 units

4,000 10 runs of 400 units

Activity Based Costing System (ABC) ABC systems follow a twostage procedure to assign overhead costs to products.

Assigning overhead to products is a difficult process.

I agree!

Activity Based Costing System (ABC) ABC systems follow a two-stage procedure to assign overhead costs to products.

Stage One Identify significant activities and assign overhead costs to each activity in proportion to resources used.

Let’s begin by identifying our major activities.

Activity Based Costing System (ABC) ABC systems follow a two-stage procedure to assign overhead costs to products.

Stage Two Identify cost drivers appropriate to each activity and allocate overhead to the products.

Overhead assigned to activities are called “activity cost pools.”

Machinery Cost Pool Total budgeted cost = $1,212,600

STAGE TWO Calculate the pool rate

Cost Assignment

Budgeted Machinery Costs = $1,212,600 Budgeted Machine Hours 43,000 = $28.20/hour

Mode I: $28.20 per hr. 1 hr. per unit $28.20 per unit

Mode II: $28.20 per hr. 1.25 hr. per unit $35.25 per unit

Mode III: $28.20 per hr. 2 hr. per unit $56.40 per unit

STAGE ONE Calculation of total setup cost

Activity cost pool

Total budgeted setup cost $20 per hour 10 hr. per setup $200 cost per setup 15 production runs $ 3,000 Total

Setup Cost Pool Total budgeted cost = $3,000

STAGE TWO Calculate the pool rate

Cost Assignment

Budgeted Setup Costs Planned Production Runs

Mode I: (1 Run) $200 per run 10,000 units per run = $.02 per unit

= $3,000 15 runs = $200 per run

Traditional costing understates the cost of complex, low volume products.

Two Key Points A large proportion of nonunit-level activities A unit-level cost driver, such as direct labor, machine hours, or throughput, will not be able to assign the costs of non-unit-level activities accurately.

Product diversity When the consumption ratios differ widely between activities, no single cost driver will accurately assign the resulting overhead costs.

Interviewing and Paper Trails The information for ABC systems initially comes from interviews with employees in the support departments and a review of each department’s records.

Storyboarding A procedure used to develop a detailed process flow chart, which visually represents activities and the relationships among activities. Step 1 Step 2 Step 3 Step 4

These are the steps we follow to build a memory board.

Direct versus Indirect Costs Volume-Based Costing Activity-Based Costing All production costs An effort is made to except direct account for as many materials and direct costs as possible as labor are lumped direct costs of together in one production. overhead cost pool. Indirect Costs

Indicators of Need for ABC Direct labor is a small percentage of total costs

Product-line profit margins are hard to explain

Sales are increasing, but profits are declining.

Line managers do not believe the product costs reports

Marketing does not use costs reports for pricing decisions

Some products that have reported high profit margins are not sold by competitors
