Optic Vision Pty Ltd, a manufacturer of fibre-optic communications equipment, uses a job costing system. Since the production process is heavily automated, manufacturing overhead is applied on the basis of machine hours using a predetermined overhead rate. The current annual rate of $45 per machine hour is based on estimated manufacturing overhead costs of $3,600,000 and an estimated cost driver level of 80,000 machine hours.
Operations for the current year have been completed, and all 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 costs from work in process to finished goods for the jobs completed in December, and the transfer of costs from finished goods to cost of goods sold for the jobs that have been sold during December.
Summarised data as at 30 November, and for December, are presented in the following table. Job numbers T11-007, N11-013 and N11-015 were completed during December. All completed jobs except Job number N11-013 had been turned over to customers by the close of business on 31 December.
