Teledex Company manufactures products to customers specifications and operates a job order costing system. Manufacturing overhead cost is applied to jobs on the basis of direct labor cost. The following estimates were made at the beginning of the year: | Department | | | | | | Fabricating | Machining | Assembly | Total Plant | Direct labor | $ | 218,000 | $ | 109,000 | $ | 327,000 | $ | 654,000 | Manufacturing overhead | $ | 381,500 | $ | 436,000 | $ | 98,100 | $ | 915,600 | | Jobs require varying amounts of work in the three departments. The Koopers job, for example, would have required manufacturing costs in the three departments as follows: | | Department | | | | | | Fabricating | Machining | Assembly | Total Plant | Direct materials | $ | 4,800 | $ | 500 | $ | 3,200 | $ | 8,500 | Direct labor | $ | 6,400 | $ | 800 | $ | 8,000 | $ | 15,200 | Manufacturing overhead | | ? | | ? | | ? | | ? | | The company uses a plantwide overhead rate to apply manufacturing overhead cost to jobs. | Required: | 1. | Assuming use of a plantwide overhead rate: | a. | Compute the rate for the current year. | | | b. | Determine the amount of manufacturing overhead cost that would have been applied to the Koopers job. | | | 2. | Suppose that instead of using a plantwide overhead rate, the company had used a separate predetermined overhead rate in each department. Under these conditions: | a. | Compute the rate for each department for the current year. | | | b. | Determine the amount of manufacturing overhead cost that would have been applied to the Koopers job. | | | 4. | Assume that it is customary in the industry to bid jobs at 150% of total manufacturing cost (direct materials, direct labor, and applied overhead). | a. | What was the company's bid price on the Koopers job if a plantwide overhead rate had been used to apply overhead cost? | | | b. | What would the bid price have been if departmental overhead rates had been used to apply overhead cost? | | | 5. | At the end of the year, the company assembled the following actual cost data relating to all jobs worked on during the year. | | Department | | | Cutting | Machining | Assembly | Total plant | Direct materials | $ | 208,000 | $ | 17,800 | $ | 132,000 | $ | 357,800 | Direct labor | | 228,000 | | 126,000 | | 280,000 | | 634,000 | Manufacturing overhead | $ | 393,000 | $ | 478,000 | $ | 86,700 | $ | 957,700 | | a. | Compute the underapplied or overapplied overhead for the year, assuming that a plantwide overhead rate is used. | | | b. | Compute the underapplied or overapplied overhead for the year, assuming that departmental overhead rates are used. (Enter overapplied overhead costs as negative amounts and underapplied overhead costs as positive amounts.) | | | |
