Activity Based Department Rate Product Costing and Product Cost Distortions Big Sound Inc manufactures two products: receivers and loudspeakers. The factory overhead incurred is as follows: Indirect labor $400,400 Subassembly Department 198,800 Final Assembly Department 114,800 Total $714,000 The activity base associated with the two production departments in direct labor hours. The indirect labor can be assigned to two different activities as follows Setup Activity Budgeted Activity Cost Activity Base $138,600 Number of setups Quality control 261,800 Number of inspections Total $400,400 The activity bate usage quantities and units produced for the two products follow: Number of Setups Number of Inspections 450 Direct Labor Hours -Subassembly Direct Labor Hours-Final Assembly 525 Units Produced Receivers 0 875 Loudspeakers 320 1.750 525 875 7,000 7,000 14,000 Total 400 2,200 1,400 1,400 Required: 1. Determine the factory overhead rates under the multiple production department rate method. Assume that indirect labor is associated with the production departments, so that the total factory overhead is $420,000 and $294,000 for the Subassembly and Final Assembly departments, respectively, Department Production Department Rate Subassembly Department per direct labor hour Final Assembly Department per direct lobor hour 2. Determine the total and per unit foctory overhead costs allocated to each product, using the multiple production department overhead rates in (1) Round per unit amounts to the nearest whole cent, Product Total Factory Overhead Factory Overhead Per Unit Receivers Loudspeakers 3. Determine the activity rates, assuming that the indirect labor is associated with activities rather than with the production departments, Round per unit amounts to the nearest whole cent. Activity Activity Rate Setup per setup Quality Control per inspection Subassembly Department per direct labor hour Final Assembly Department per direct labor hour 4. Determine the total and per-unit cost assigned to each product under activity based costing. Round the per unit amounts to the nearest whole cent Product Total Activity Cost Activity Cost Per Unit Receivers Loudspeakers 5. Comment on the difference in the per unit overhead alocated to each product under the multiple production department factory overhead rate and activity-based costing methods The activity based overhead allocation reveals that loudspeakers are costly on a per unit basis than are the receivers. The multiple Final Assembly Department per direct labor hour 2. Determine the total and per unit factory overhead costs allocated to each product, using the multiple production department overhoed rates in (1) Round per unit amounts to the nearest whole cent. Product Total Factory Overhead Factory Overhead Per Unit Receivers Loudspeakers 3. Determine the activity rates, assuming that the indirect labor is associated with activities rather than with the production departments, Round per u amounts to the nearest whole cent. Activity Activity Rate Setup per setup Quality Control per inspection Subassembly Department per direct labor hour Final Assembly Department per direct labor hour 4. Determine the total and per-unit cost assigned to each product under activity based costing Round the per unit amounts to the nearest whole cent Product Total Activity Cost Activity Cost Per Unit Receivers Loudspeakers 5. Comment on the difference in the per-unit overhead allocated to each product under the multiple production department factory overhead rate and activity based conting methods The activity based overhead allocation reveals that loudspeakers are costly on a per unit basis than are the receivers. The multiple production department rate method determines that the per-unit factory overhead is for the two products. The multiple production department factory overhead rate method distort the unit costs because all factory overhead is assumed to be to direct labor hours Loudspeakers have setups and inspection activities than do receivers. Thus, Loudspeakers have activity costs per unit than do receivers
