Opticom, Inc. a manufacturer of fiber optic communications equipment, use a job-order costing system. Since the production process is heavily automated, manufacturing overhead is applied on the basis of machine hour using a predetermined overhead rate. The current annual rate of $30 per machine hour is based on budgeted manufacturing overhead cost of $2,400,000 and a budgeted activity level of 80,000 machine hours (the company’s estimated practical capacity). Operations for the year have been completed, and all of the accounting entries have been made for the year except the application of manufacturing overhead to the jobs worked on during December, the transfer of cost from Work in Process to Finished Good for the Jobs, completed in December, and the transfer of cost from Finished Goods to cost of Goods Sold for the jobs that have been sold during December. Summarized data as of November 30 and for the month of December are presented in the following table. Jobs T11-007, N11-013, N11-015 were completed during December. All completed job except N11-013 had been turned over to customers by the close of business on December 31.     Work in Process December Activity Job No Balance Nov 30 Direct   Material Direct Labor Machine   Hours T11-007 $ 174,000 $ 3,000 $9,000 300 N11-013 110,000 8,000 24,000 1,000 N11-015 0 51,200 53,400 1,400 D12-002 0 75,800 40,000 2,500 D12-003 0 52,000 33,600 800 Total $284,000 $190,000 $160,000 6,000         Operating Activity Activity Through   November 30 December Activity Actual manufacturing overhead incurred:     Indirect material $    250,000 $ 18,000 Indirect labor 690,000 60,000 Utilities 490,000 44,000     Depreciation 770,000 70,000 Total Overhead $2,200,000 $ 192,000       Other Data:     Raw Material purchases* $1,930,000 $ 196,000 Direct-labor cost $1,690,000 $ 160,000 Machine hours 73,000 6,000     Account Balances at Beginning of Year                 January 1   Raw-material Inventory *                                          $ 210,000   Work-in-process inventory                                           120,000   Finished-goods inventory                                              250,000       *Raw material purchases and raw-material inventory consist of both direct and indirect materials.
