Then, apply the ABC 4-step process to allocate OH costs at the cost objects (pens of different color). ABC 4 step process: Step 1: Identify activities (cost pools) and associated cost drivers. Step 2: Assign OH costs to activity cost pools. Step 3: Calculate Cost-driver rates. Step 4: Allocate OH costs from activities to the 4 products (black, blue, red, and purple pens) 3. Compare the OH costs allocated to each type of pen based on traditional costing (case Exhibit 1) with your ABC cost-allocation. Which products are undercosted (traditional costing allocates less OH costs relative to ABC) and which overcosted? Explain your findings. (250-300 words) (15p)
