  8. Unit Cost Computations Harvey Company produces a single productwith the following information available:

  9. Unit Cost Computations Unit product cost is determined as follows: Under absorption costing, all production costs, variable and fixed, are included when determining unit product cost. Under variable costing, only the variable production costs are included in product costs.

  10. Learning Objective 2 Prepare income statements using both variable and absorption costing.

  11. Income Comparison ofAbsorption and Variable Costing Let’s assume the following additional information for Harvey Company. • 20,000 units were sold during the year at a priceof $30 each. • There is no beginning inventory. Now, let’s compute net operatingincome using both absorptionand variable costing.

  12. Absorption Costing Fixed manufacturing overhead deferred in inventory is 5,000 units × $6 = $30,000.

  14. Learning Objective 3 Reconcile variable costing and absorption costing net operating incomes and explain why the two amounts differ.

  15. Comparing the Two Methods

  16. Fixed mfg. overhead $150,000 Units produced 25,000 units = = $6 per unit Comparing the Two Methods We can reconcile the difference betweenabsorption and variable income as follows:

  17. Extended Comparisons of Income Data Harvey Company – Year Two

  18. Unit Cost Computations Since the variable costs per unit, total fixed costs, and the number of units produced remained unchanged, the unit cost computations also remain unchanged.

  19. Unit product cost. Absorption Costing Fixed manufacturing overhead released from inventory is 5,000 units × $6 = $30,000.

  21. Fixed mfg. overhead $150,000 Units produced 25,000 units = = $6 per unit Comparing the Two Methods We can reconcile the difference betweenabsorption and variable income as follows:

  23. Summary of Key Insights

  24. Learning Objective 4 Understand the advantages and disadvantages of both variable and absorption costing.

  25. Impact on the Manager Opponents of absorption costing argue thatshifting fixed manufacturing overhead costsbetween periods can lead to faulty decisions. These opponents argue that variable costing incomestatements are easier to understand because net operatingincome is only affected by changes in unit sales. Thisproduces net operating income figures that areconsistent with managers’ expectations.

  26. CVP Analysis, Decision Makingand Absorption costing Absorption costing does not dovetail with CVP analysis, nor does it support decision making. It treats fixed manufacturing overhead as a variable cost. It assigns per unit fixed manufacturing overhead costs to production. • Treating fixed manufacturing overhead as a variable cost can: • Lead to faulty pricing decisions and faulty keep-or-drop decisions. • Assigning per unit fixed manufacturing overhead costs to production can: • Potentially produce positive net operating income even when the number of units sold is less than the breakeven point.

  27. Since top executivesare typically evaluated based on earnings reported to shareholdersin external reports, they may feel that decisions should be based on absorption costing data. External Reporting and Income Taxes To conform toGAAP requirements,absorption costing must be used forexternal financial reports in the United States. Under the TaxReform Act of 1986,absorption costing must beused when filling out income tax returns.

  28. Consistent with CVP analysis. Management findsit more useful. Net operating income is closer tonet cash flow. Consistent with standardcosts and flexible budgeting. Easier to estimate profitabilityof products and segments. Impact of fixed costs on profits emphasized. Profit is not affected bychanges in inventories. Advantages of Variable Costingand the Contribution Approach Advantages

  29. Variable versus Absorption Costing Fixed manufacturingcosts must be assignedto products to properlymatch revenues andcosts. Fixed manufacturing costs are capacity costsand will be incurredeven if nothing isproduced. VariableCosting AbsorptionCosting

  30. Variable Costing and the Theory of Constraints (TOC) Companies involved in TOC use a form of variable costing. However, one difference of the TOC approach is that it treats direct labor as a fixed cost for three reasons: • Many companies have a commitment to guarantee workers a minimum number of paid hours. • Direct labor is usually not the constraint. • TOC emphasizes the role direct laborers play in driving continuous improvement. Since layoffs often devastate morale, managers involved in TOC are extremely reluctant to lay off employees.

  31. Impact of Lean Production When companies use Lean Production . . . Productiontends to equalsales . . . So, the difference between variable and absorption income tends to disappear.
