Zwahlen Corporation has an activity-based costing system with three activity cost pools-Processing, Setting Up, and Other. Costs in the Processing cost pool are assigned to products based on machine-hours (MHS) and costs in the Setting Up cost pool are assigned to products based on the number of batches. Costs in the Other cost pool are not assigned to products.
