CHAPTER 4 JOB ING 4-17 (20 min.) Actual costing, normal costing, accounting for manufacturing overhead. 1. Budgeted manufacturing overhead rate Budgeted manufacturing overhead costs Budgeted direct manufacturing labor costs $2,700,000 1.80 or 185% $1,500,000 Actual manufacturing overhead rate Actual manufacturing overhead costs Actual direct manufacturing labor costs $2,755,000 1.9 or 190% $1,450,000 2. Costs of Job 626 under actual and normal costing follow: Actual Costing Normal Costing Direct materials $ 40,000 $ 40,000 Direct manufacturing labor costs 30,000 30,000 Manufacturing overhead costs $30,000 1.90; $30,000 1.80 57,000 54,000 Total manufacturing costs of Job 626 $127,000 $124,000 4-1
3. Total manufacturing overhead allocated under normal costing Actual manufacturing labor costs Budgeted overhead rate $1,450,000 1.80 $2,610,000 Underallocated manufacturing overhead Actual manufacturing overhead costs Manufacturing overhead allocated $2,755,000 $2,610,000 $145,000 There is no under- or overallocated overhead under actual costing because overhead is allocated under actual costing by multiplying actual manufacturing labor costs and the actual manufacturing overhead rate. This, of course equals the actual manufacturing overhead costs. All actual overhead costs are allocated to products. Hence, there is no under- or overallocatead overhead. 4-2

Budgeted indirectcost rate Actual indirectcost rate Budgeted indirect costs Budgeted direct labor-hours $50 per direct labor-hour $8,000,000 160,000 hours Actual indirect costs Actual direct labor-hours $6,888,000 164,000 hours $42 per direct labor-hour These rates differ because both the numerator and the denominator in the two calculations are different one based on budgeted numbers and the other based on actual numbers. 2a.

Normal costing enables Anderson to report a job cost as soon as the job is completed, assuming that both the direct materials and direct labor costs are known at the time of use. Once the 900 direct labor-hours are known for the Laguna Model (June 2007), Anderson can compute the $187,726 cost figure using normal costing. Anderson can use this information to manage the costs of the Laguna Model job as well as to bid on similar jobs later in the year. In contrast, Anderson has to wait until the December 2007 year-end to compute the $180,526 cost of the Laguna Model using actual costing. Although not required, the following overview diagram summarizes Anderson Construction s job-costing system. 4-3

Raymond Company began May 2009 with no work-in-process inventory. During May, it started and finished M1. It also started M2, which is still in work-in-process inventory at the end of May. M2 s manufacturing costs up to this point, $410,000, remain as a debit balance in the Work-in-Process Inventory account at the end of May 2009. 4-8

(a) Actual Costing Direct Costs Indirect Costs Total Job Costs $58 120 $ 6,960 48 120 5,760 $12,720 (b) Normal Costing $58 120 $ 6,960 45 120 5,400 $12,360 (c) Variation of Normal Costing $60 120 $ 7,200 45 120 5,400 $12,600 All three costing systems use the actual professional labor time of 120 hours. The budgeted 110 hours for the Pierre Enterprises audit job is not used in job costing. However, Chirac may have used the 110 hour number in bidding for the audit. The actual costing figure of $12,720 exceeds the normal costing figure of $12,360 because the actual indirect-cost rate ($48) exceeds the budgeted indirect-cost rate ($45). The normal costing figure of $12,360 is less than the variation of normal costing (based on budgeted rates for direct costs) figure of $12,600, because the actual direct-cost rate ($58) is less than the budgeted direct-cost rate ($60). 4-9

Machining Finishing Manufacturing overhead incurred (actual) $11,200,000 $7,900,000 Manufacturing overhead allocated 220,000 hours $50 11,000,000 200% of $4,100,000 8,200,000 Underallocated manufacturing overhead $ 200,000 Overallocated manufacturing overhead $ 300,000 Total overallocated overhead $300,000 $200,000 $100,000 6. A homogeneous cost pool is one where all costs have the same or a similar cause-andeffect or benefits-received relationship with the cost-allocation base. Solomon likely assumes that all its manufacturing overhead cost items are not homogeneous. Specifically, those in the Machining Department have a cause-and-effect relationship with machine-hours, while those in the Finishing Department have a cause-and-effect relationship with direct manufacturing labor costs. Solomon believes that the benefits of using two cost pools (more accurate product costs and better ability to manage costs) exceeds the costs of implementing a more complex system. 4-12
