5 Fall 2010Mugan5/37 Absorption Costing Absorption costing allocates variable and fixed overhead costs to products. Finished Goods Inventory Valuation Cost of Goods Sold Cost of Goods Manufactured

6 Fall 2010Mugan6/37 Product Costing Procedures in Organizations Process Costing Job-order Costing Distinct jobs or batches of units. Costs accumulated separately by job. Typical job order cost applications: Special-order printing Building construction Also used in service industry Hospitals Law firms

7 Fall 2010Mugan7/37 Product Costing Procedures in Organizations Process Costing Job-order Costing Typical process cost applications: Petrochemical refinery Paint manufacturer Paper mill

8 Fall 2010Mugan8/37 Job-Order Costing Traced directly to each job TheJobTheJob Direct labor Direct materials Manufacturing overhead (MOVH) Applied (added) to each job using a predetermined rate

9 Fall 2010Mugan9/37 Job-Order Costing Part of the job cost Materials Requisition and Time tickets Direct material s and labor Indirect materials and labor Manufacturing Overhead Control Account Raw materials could be used as direct or indirect product cost. An employee’s time may be either direct or indirect.

14 Fall 2010Mugan14/37 Allocation Process Define the cost objects. Accumulate indirect costs in cost pools. Choose an allocation base. Estimate an application rate. Allocate indirect costs based on use of the allocation base

15 Fall 2010Mugan15/37 Over- and Underabsorbed Overhead Overabsorbed overhead Underabsorbed overhead Overabsorbed overhead Underabsorbed overhead

16 Fall 2010Mugan16/37 Over- and Underabsorbed Overhead SOLUTION Applied Overhead = POHR × Actual Direct Labor Hours Applied Overhead = TL 6.00 per DLH × 100,000 DLH = TL 600,000 SOLUTION Applied Overhead = POHR × Actual Direct Labor Hours Applied Overhead = TL 6.00 per DLH × 100,000 DLH = TL 600,000 XYZ’s actual overhead for the year was TL650,000 and a total of 100,000 direct labor hours were worked. Using XYZ’s predetermined overhead rate of TL 6.00 per direct labor hour, how much overhead was applied to XYZ’s jobs during the year?

17 Fall 2010Mugan17/37 Accounting for Over- and Underabsorbed Overhead Three basic approaches  Prorate among work-in-process, finished goods, and cost of goods sold.  Adjust cost of goods sold.  Recalculate the application rate and apply to all the jobs during the period.

How many equivalent units of production did Ames have for the period? a. 10,000 b. 11,500 c. 13,500 d. 15,000 Equivalent Units Question

27 Fall 2010Mugan27/37 For the current period, Ames started 15,000 units and completed 10,000 units, leaving 5,000 units in process 30 percent complete. How many equivalent units of production did Ames have for the period? a. 10,000 b. 11,500 c. 13,500 d. 15,000 For the current period, Ames started 15,000 units and completed 10,000 units, leaving 5,000 units in process 30 percent complete. How many equivalent units of production did Ames have for the period? a. 10,000 b. 11,500 c. 13,500 d. 15,000 10,000 units + (5,000 units ×.30) = 11,500 equivalent units Equivalent Units Question

28 Fall 2010Mugan28/37 Calculating and Using Equivalent Units of Production To calculate the cost per equivalent unit for the period: Cost per equivalent unit = Costs for the period Equivalent units for the period

29 Fall 2010Mugan29/37 Now assume that Ames incurred $27,600 in production costs for the 11,500 equivalent units. What was Ames’ average cost per equivalent unit for the period? a.$1.84 b.$2.40 c.$2.76 d.$2.90 Now assume that Ames incurred $27,600 in production costs for the 11,500 equivalent units. What was Ames’ average cost per equivalent unit for the period? a.$1.84 b.$2.40 c.$2.76 d.$2.90 Equivalent Units Question

30 Fall 2010Mugan30/37 Now assume that Ames incurred $27,600 in production costs for the 11,500 equivalent units. What was Ames’ average cost per equivalent unit for the period? a.$1.84 b.$2.40 c.$2.76 d.$2.90 Now assume that Ames incurred $27,600 in production costs for the 11,500 equivalent units. What was Ames’ average cost per equivalent unit for the period? a.$1.84 b.$2.40 c.$2.76 d.$2.90 $27,600 ÷ 11,500 equivalent units = $2.40 per equivalent unit Equivalent Units Question

31 Fall 2010Mugan31/37 What portion of the $27,600 in production costs was assigned to work-in-process inventory and what amount was assigned to completed units for the period? a.$0 and $27,600 b.$7,600 and $20,000 c.$3,600 and $24,000 d.$12,000 and $15,600 What portion of the $27,600 in production costs was assigned to work-in-process inventory and what amount was assigned to completed units for the period? a.$0 and $27,600 b.$7,600 and $20,000 c.$3,600 and $24,000 d.$12,000 and $15,600 Equivalent Units Question

32 Fall 2010Mugan32/37 What portion of the $27,600 in production costs was assigned to work-in-process inventory and what amount was assigned to completed units for the period? a.$0 and $27,600 b.$7,600 and $20,000 c.$3,600 and $24,000 d.$12,000 and $15,600 What portion of the $27,600 in production costs was assigned to work-in-process inventory and what amount was assigned to completed units for the period? a.$0 and $27,600 b.$7,600 and $20,000 c.$3,600 and $24,000 d.$12,000 and $15,600 Work-in-process: 1,500 equivalent units @ $2.40 = $3,600 Completed units: 10,000 equivalent units @ $2.40 = $24,000 Equivalent Units Question

33 Fall 2010Mugan33/37 Equivalent Units When there are partially completed units in beginning inventory, work efforts during the period can be categorized as follows: Ê Work to complete beginning work-in-process Ë Work on units started and completed during the period Ì Work on units in ending work-in-process When there are partially completed units in beginning inventory, work efforts during the period can be categorized as follows: Ê Work to complete beginning work-in-process Ë Work on units started and completed during the period Ì Work on units in ending work-in-process

34 Fall 2010Mugan34/37 Equivalent Units - Example ACE started June with 250 partially completed units in work-in-process (30% complete). During June, ACE completed the units in work- in-process and started an additional 1,200 units. There were 300 units in ending work-in-process on June 30. They were 40% complete. How many total equivalent units did ACE produce during June? Continue

35 Fall 2010Mugan35/37 Equivalent Units - Example Since 30% of the work was done on these units in May, the remaining 70% of the work is done in June.

36 Fall 2010Mugan36/37 Equivalent Units - Example Since 1,200 units were started during June, and 300 of those units are still in work-in-process on June 30, 900 units were started and completed during June.

37 Fall 2010Mugan37/37 Equivalent Units - Example 40% of the work was done on these units in June.
