Allocation of manufacturing overhead and disposition of overallocation or underallo- cation. (SMA, heavily adapted) Nicole Limited is a company that produces machinery to customer order. Its job costing system (using normal costing) has two direct cost categories (direct materials and direct manufacturing labour) and one indirect cost pool (manufacturing overhead, allocated using a budgeted rate based on direct manufacturing labour costs). The budget for 2010 was:

At the end of 2010, two jobs were incomplete: No. 1768B (total direct manufacturing labour costs were $15,000) and No. 1819C (total direct manufacturing labour costs were $48,000).
Machine time totalled 318 hours for No. 1768B and 654 hours for No. 1819C. Direct materials issued, to No. 1768B amounted to $30,600. Direct materials for No. 1819C came to $5 6,800.
Total charges to the Manufacturing Overhead Control account for the year were $406,200. Direct manufacturing labour charges made to all jobs were $650,000, representing 25,000 direct manufacturing labour-hours (DMLH).
There were no beginning inventories. In addition to the ending work-in-process, the ending finished goods showed a balance of $2 04,500 (including a direct manufacturing labour cost component of $60,000). Sales for 2010 totalled $3,124,000, cost of goods sold was $2,200,000, and marketing costs were $523,900.
Nicole prices on a cost-plus basis. It currently uses a guideline of cost plus 40% of cost.
REQUIRED 1. Prepare a detailed schedule showing the ending balances in the inventories and cost of goods sold (before considering any underallocated or overallocated manufacturing overhead).
Show also the manufacturing overhead allocated to these ending balances.
2. Compute the underallocated or overallocated manufacturing overhead for 2010.

3. Prorate the amount computed in requirement 2 on the basis of:

a. ‘The ending balances (before proration) of work-in-process, finished goods, and cost of goods sold

b. The allocated overhead amount (before proration) in the ending balances of work-inprocess, finished goods, and cost of goods sold 4. Assume that Nicole decides to immediately write off to Cost of Goods Sold any underallocated or overallocated manufacturing overhead. Will operating income be higher or lower than the operating income that would have resulted from the proration in requirements 3

(a) and 3(b)?
5. Calculate the cost of job No. 1819C if Nicole Limited had used the adjusted allocation rate approach to disposing of underallocated or overallocated manufacturing overhead in 2010.LO1
