Quick Check ?
  • Which method will produce the highest values
    for work in process and finished goods
    inventories?
  • a. Absorption costing.
  • b. Variable costing.
  • c. They produce the same values for these
    inventories.
  • d. It depends. . .

  • Which method will produce the highest retained
    earnings? (Hint Remember the balance sheet
    equation.)
  • a. Absorption costing
  • b. Variable costing
  • c. There would be no difference in retained
    earnings under the two methods.

15
Quick Check ?
  • If the Internal Revenue Service lets you use
    either absorption or variable costing, which
    method should you choose to minimize your taxes?
    (Assume that once you have decided which method
    to use, you cannot later change.)
  • a. Absorption costing.
  • b. Variable costing.
  • c. The two methods would have the same effect
    on taxes.

17
Overview of Absorption and Variable Costing
Lets put some numbers to theissue and see if it
willsharpen our understanding.
18
Unit Cost Computations
  • Harvey Co. produces a single product with the
    following information available

19
Unit Cost Computations
  • Unit product cost is determined as follows

Selling and administrative expenses arealways
treated as period expenses and deducted from
revenue.
20
Income Comparison of Absorption and Variable
Costing
  • Harvey Co. had no beginning inventory, produced
    25,000 units and sold 20,000 units this year.

Income Comparison of Absorption and Variable
Costing
  • Harvey Co. had no beginning inventory, produced
    25,000 units and sold 20,000 units this year.

22
Income Comparison of Absorption and Variable
Costing
  • Now lets look at variable costing by Harvey Co.

23
Quick Check ?
  • The net operating income under absorption
    costing was 120,000 and under variable costing
    it was 90,000 because of higher expenses. Where
    is the missing 30,000 under absorption costing?
  • a. It has disappeared into an accounting black
    hole.
  • b. It is in ending inventories.
  • c. It represents taxes that have been saved.
  • d. The 30,000 wasnt a real cost, so nothing
    is really missing.

25
Income Comparison of Absorption and Variable
Costing
  • Lets compare the methods.

26
Reconciliation
We can reconcile the difference
betweenabsorption and variable income as follows
27
Extending the Example
28
Harvey Co. Year 2
  • In its second year of operations, Harvey Co.
    started with an inventory of 5,000 units,
    produced 25,000 units and sold 30,000 units.

29
Harvey Co. Year 2
  • Unit product cost is determined as follows

No change in Harveys cost structure.
30
Harvey Co. Year 2
Now lets look at Harveys income
statement assuming absorption costing is used.
31

Next, well look at Harveys income
statement assuming
is used.

Variable versusAbsorption Costing
40
Variable versusAbsorption Costing
Absorption costing product costs are misleading
for decision making.
41
Note on theEffects of Volume
Absorption CostingCost of goods sold decreases
because production exceeds sales, leaving a
portion of fixedmanufacturing costs in inventory.

43
Impact of JIT Inventory Methods
In a JIT inventory system . . .
Productiontends to equalsales . . .
So, the difference between variable
and absorption income tends to disappear.
