5. Cost of salaries, wages, and fringe benefits for personnel who work directly on manufactured products. Direct Labor Example: Wages paid to an automobile assembly worker. Example: Wages paid to an automobile assembly worker.

6. All other manufacturing costs Manufacturing Overhead Materials used to support the production process. Examples: lubricants and cleaning supplies used in an automobile assembly plant. Indirect Labor Indirect Material Other Costs

7. All other manufacturing costs Manufacturing Overhead Cost of personnel who do not work directly on the product. Examples: maintenance workers, janitors and security guards. Indirect Labor Indirect Material Other Costs

8. All other manufacturing costs Manufacturing Overhead Examples: depreciation on plant and equipment, property taxes, insurance, utilities, overtime premium, and unavoidable idle time. Indirect Labor Indirect Material Other Costs

9. Accounting for Factory Overhead Methods for assigning overhead costs to the products is an important part of accurately measuring product costs. Learning Objective 1

10. Budgeted Overhead Application Rates 1. Select one or more cost drivers. 2. Prepare a factory overhead budget. 3. Compute the factory overhead rate. 4. Obtain actual cost-driver data. 5. Apply the budgeted overhead to the products. to the products. 6. Account for any differences between the amount of actual and applied overhead. amount of actual and applied overhead.

11. Budgeted overhead application rate = Total budgeted factory overhead ÷ Total budgeted amount of cost driver Budgeted Overhead Application Rates Overhead rates are budgeted; they are estimates. The budgeted rates are used to apply overhead based on actual events.

12. Illustration of Overhead Application The company’s budgeted manufacturing overhead for the machining department is $277,800. Budgeted machine hours are 69,450. The budgeted overhead application rate is: $277,800 ÷ 69,450 = $4 per machine hour Enriquez Machine Parts Company selects a single cost- allocation in each department for applying overhead, machine hours in machining and direct-labor in assembly.

13. MachiningAssembly Budgeted manufacturing overhead$227,800$103,200 Budgeted machine hours 69,450 Budgeted direct-labor cost$206,400 Budgeted overhead rate, per machine hour$4 Budgeted overhead rate, per direct-labor dollar50%

14. Illustration of Overhead Application Suppose that at the end of the year Enriquez had used 70,000 hours in Machining and incurred $190.000 of direct-labor cost in assembly How much overhead was applied the products produced? 70,000 * 4+190,000 * 0.5 = $ 375,000

15. Choice of Cost-Allocation Bases No one cost –allocation base is right for all situations. The accountant’s goal is to find the cost- allocation base that best links cause and effect.

16. Choice of Cost-Allocation Bases A separate cost pool should be Identified for each cost-allocation base. Base 1 Pool 1 Base 2 Pool 2

17. Choice of Cost-Allocation Bases 80-20 rule 20% of the bases 80% of the overheads

18. Normalized Overhead Rates “Normal” product costs include an average or normalized chunk of overhead. Actual direct material + Actual direct labor + Normal applied overhead = Cost of manufactured product

20. Disposing of Under-applied or Over-applied Overhead Suppose that Enriquez applied $375,000 to its products. Also, suppose that Enriquez actually incurred $392,000 of actual manufacturing overhead during the year. $392,000 actual –375,000 applied $ 17,000 Under-applied $ 17,000 Under-applied The $375,000 becomes part of Cost of Goods Sold when the product is sold. The $17,000 must also become an expense.

21. Disposing of Under-applied or Over-applied Overhead The applied overhead is $17,000 less than the amount incurred. It is: Over-applied overhead occurs when the amount applied exceeds the amount incurred.

22. Immediate Write-Off Manufacturing Overhead 392,000375,000 17,000 17,000 0 Cost of Goods Sold 17,000 Incurred Overhead (Actual) Applied Overhead (Budgeted) This method regards the $17,000 as a reduction in current income and adds it to Cost of Goods Sold.

23. Prorating Among Inventories This method prorates the $17,000 of Under-applied overhead to Work-In Process (WIP), Finished Goods, and Cost of Goods Sold accounts assuming the following ending account balances: Work-in-Process Inventory$ 155,000 Finished Goods Inventory 32,000 Cost of Goods Sold 2,480,000 Total$2,667,000

24. Account balanceAllocating $17000 (under- applied) Work-in-Process Inventory $ 155,000 $17,000 × 155/2,667 = 988 Finished Goods Inventory 32,000 32,000 $17,000 × 32/2,667 = $204 Cost of Goods Sold 2,480,000 2,480,000 $17,000 × 2,480/2,667 = $15,808 Total$2,667,000

25. Variable and Fixed Application Rates The presence of fixed costs is a major reason of costing difficulties. Some companies distinguish between variable overhead and fixed overhead for product costing.

26. Variable Versus Absorption Costing Variable costing excludes fixed manufacturing overhead from the cost of products. Absorption costing includes fixed manufacturing overhead in the cost of products. VariablecostingAbsorptioncosting Learning Objective 2

30. Facts and Illustration The annual budget for fixed manufacturing overhead is $1,500,000 Budgeted production is 15,000 computers. Sales price = $500 per unit $20 per computer is variable overhead. Sales commissions = 5% of dollar sales Fixed S&A expenses = $650,000

34. Fixed-Overhead Rate The fixed-overhead rate is the amount of fixed manufacturing overhead applied to each unit of production. $1,500,000 ÷ 15,000 = $100 budgeted fixed manufacturing overhead expected volume of production expected volume of production Fixed overhead rate =

37. Variable Costing and Absorption Costing The difference between income reported under these two methods is entirely due to the treatment of fixed manufacturing costs.

38. Variable Costing and Absorption Costing On a variable-costing income statement, costs are separated into the major categories of fixed and variable. Revenue less all variable costs (both manufacturing and non-manufacturing) is the contribution margin. On an absorption-costing income statement, costs are separated into the major categories of manufacturing and non-manufacturing. Revenue less manufacturing costs (both fixed and variable) is gross profit or gross margin.

40. Why Use Variable Costing?

41. Sales, (1000unites,$6 per unit)$6,000$6,000 Costs of goods sold: direct costs & variable overhead (1000unites,$2per unit) $2,000$2,000 (1000unites,$2per unit) $2,000$2,000 fixed overhead $4,800$1,600 Gross profit$ (800)$2,400 Selling and admin. expenses 1000 1,000 Operating income, variable costing$(1,800)$1,400 production 1000 units3000 units (thousands of dollars) 20X1 20X2

42. Why Use Variable Costing? One reason is that absorption-costing income is affected by production volume while variable-costing income is not. Another reason is based on which system the company believes gives a better signal about performance.

43. Effects of Sales and Production on Reported Income Production > Sales Variable costing income is lower than absorption income. Production < Sales Variable costing income is higher than absorption income.
