Southwick Products manufactures its products in two separate departments: Machining and Assembly. Total manufacturing overhead costs for the year are budgeted at $1,056,000. Of this amount, the Machining Department incurs $600,000 (primarily for machine operation and depreciation) while the Assembly Department incurs $456,000. The company estimates that it will incur 4,000 machine hours (all in the Machining Department) and 9,600 direct labor hours (1,600 in the Machining Department and 8,000 in the Assembly Department) during the year. Southwick Products currently uses a plantwide overhead rate based on direct labor hours to allocate overhead. However, the company is considering refining its overhead allocation system by using departmental overhead rates. The Machining Department would allocate its overhead using machine hours (MH), but the Assembly Department would allocate its overhead using direct labor (DL) hours. The following chart shows the machine hours (MH) and direct labor (DL) hours incurred by Jobs 500 and 501 in each production department
