19-P1: Compute unit cost under both absorption and variable costing.

19-3

Absorption costing (also called full costing), assumes that products absorb all costs incurred to produce them.

• While widely used for financial reporting (GAAP), this costing method can result in misleading product cost information for managers’ business decisions.

Absorption Costing & Variable Costing

Under variable costing, only costs that change in total with changes in production level are included in product costs.

A performance report that excludes fixed expenses and net income is a contribution margin report. It’s bottom line is contribution margin.

We can see that the income under variable costing is also $580,000. This is because the number of units produced are equal to

the number of units sold.

Exhibit 19.12 Converting Variable Costing Income to Absorption Costing Income

To restate variable costing income to absorption costing income for 2014, we must add back the fixed overhead cost deferred in ending inventory.

Similarly, to restate variable costing income to absorption costing income for 2015, we must deduct the fixed overhead cost recognized from beginning inventory, which was incurred in 2014, but expensed in the 2015 cost of goods sold when the inventory was sold.

C 1

Planning Production: Income under Absorption Costing for Different Production

LevelsWhy is income under absorption costing

affected by the production level when

that for variable costing is not?

The answer lies in the different

treatment of fixed overhead

costs within the two methods.

19-33

So…under absorption costing, if excess units are produced, the fixed overhead cost allocated to those units is not expensed until a future period when those units

are sold.

Exactly!C 1

19-34

When 60,000 units are produced:

Fixed overhead per unit is:

$600,000/ 60,000 units = $10/unit

When 100,000 units are produced:

Fixed overhead per unit is:

$600,000/ 100,000 units = $6/unit

What would happen if IceAge’s manager decided to produce 100,000 units instead of 60,000?

The 40,000 extra units would be stored in inventory and the total production cost PER UNIT is $4 less!

Note: Income under absorption costing is $240,000 greater if management produces 40,000 more units than necessary and builds up ending inventory.

This shows that a manager can report increased income merely by producing

more and disregarding whether the excess units can be sold or not.

19-P4: Determine product selling price based on

absorption costing.

19-37

How does management determine the sales price of a product?

Although many factors impact

pricing, cost is a crucial factor!

Over the long run, price must be high enough

to cover all costs.

Absorption cost information is useful because it reflects the full costs that

sales must exceed for the company to be profitable.

P 4

19-38

We can use a three-step process to determine product selling prices:

• Step 1: Determine the product cost per unit using absorption costing.

• Step 2: Determine the target markup on product cost per unit.

• Step 3: Add the target markup to the product cost to find the target selling price

P 4

19-39

Example: IceAge will use absorption costing to determine a target selling price.

Exhibit 19.16 Determining Selling Price with Absorption Costing

Step 1 Absorption cost per unit (from Exhibit 19.3) $25

Step 2 Target markup per unit ($25 times 60%) 15

Step 3 Target selling price per unit $40

Start with product cost.

Then, management needs to determine a target markup.

In this example, they chose a markup of 60% of cost. So the target selling price is $40 per unit.

P 4

19-40

Controllable vs. Uncontrollable Costs?

• Managers are responsible for their controllable costs. • A cost is controllable if a manager has the

power to determine the amount incurred.• Examples vary depending on the manager’s

level in the company.• Uncontrollable costs are not within the

manager’s control or influence.• Example would be production capacity.

P 4

19-41

Limitations of Reports Using Variable Costing

19-42

• For income tax purposes, absorption costing is the only acceptable basis for filings with the Internal Revenue Service (IRS) under the Tax Reform Act of 1986.

• Absorption costing is the only acceptable basis for external reporting under both U.S. GAAP and IFRS.

• Top executives are often awarded bonuses based on income computed using absorption costing.

Realities that contribute to the widespread use of absorption costing by companies:

P 4

19-A1: Use variable costing in pricing special orders.

19-43

Setting Prices

Over the Long Run:• Price must be high enough to cover all

costs, including variable costs and fixed costs, and still provide an acceptable return to owners

19-44

A 1

Setting Prices

Over the Short Run:• Fixed production costs such as the cost to maintain

plant capacity do not change with changes in production levels.

• With excess capacity, increases in production level would increase variable production costs, but not fixed costs.

• While managers try to maintain the long-run price on existing orders, which covers all production costs, managers should accept special orders provided the special order price exceeds variable cost.

From Exhibit 19.3 Unit Cost Computation at 60,000 units

Should the company accept a special order for 1,000 pairs of skates at an offer price of $22 per pair?

Variable production cost = $15 ($4DM + $8DL + $3 VOH)

Order should be accepted because the $22 order price exceeds the $15 variable cost of the product.
