However, the majority of overheads are more closely related to machine hours than direct labour hours. The company has recently redesigned its cost system by recovering overheads using two volume-related bases: machine hours and material handling overhead rate for recovering overheads of the receiving department. Both the current and previous cost system reported low profit margin for product X, which is the companys highest selling product. The management accountant has recently attended a conference on activity-based costing and the overhead cost for the last period have been analysed by major activities in order to compute activity-based costs. Required: 3 (a) Compute the product cost using a traditional volume-related costing system based on the assumptions that: i. All overheads are recovered on the basis of direct labour hours ii. The overheads of the receiving department are recovered by a material handling overhead rate and the remaining overheads are recovered using a machine hour rate. (5 marks) (b) Compute product costs using an activity-based costing system.
