9-7 The Death Spiral This is a process that begins by attempting to increase price to meet reported product cost. This may result in demand for even fewer units. LO 9-1

9-8 Two-Stage Cost Allocation LO 9-2 Explain how a two-stage product costing system works. Allocate overhead costs to departments. Allocate department overhead costs to the products or services. LO 9-2

9-13 Plantwide versus Department-Specific Rates LO 9-3 Compare and contrast plantwide and department allocation methods. All overhead costs are recorded in one cost pool and applied to products using one overhead allocation rate. LO 9-3

9-14 Overhead costs are traced to separate departments and applied to products using a department allocation rate. LO 9-3 Plantwide versus Department-Specific Rates

9-16 Activity-Based Costing (ABC) LO 9-4 Explain how activity-based costing and a two-stage product system are related. ABC is a costing method that first assigns costs to activities and then assigns them to products based on the products’ consumption of activities. Assign costs to activities. Assign costs to products based on the use of each activity LO 9-4

9-17 Activity-Based Costing (ABC) Activities consume resources Products consume activities LO 9-4

9-18 Developing Activity-Based Costs Step 1:Identify the activities that consume resources and assign costs to them. Step 2:Identify the cost driver(s) associated with each activity. Step 3:Compute a cost rate per cost driver unit or transaction. Step 4:Assign costs to products by multiplying the cost driver rate by the volume of cost driver units consumed by the product. LO 9-4

9-19 Cost Drivers Cost drivers are factors that cause or “drive” an activity’s costs. Identified Activity Setting up machines Handling material Machining Packaging and shipping LO 9-4 Identified Cost Driver ?
