Wilkerson, a mid-sized manufacturing company that produces water purification systems, is seeing a decline in margins. The company has one production department that machines and assembles three products: valves, pumps, and flow controllers. Wilkerson uses a volume-based costing system that may be incorrectly allocating overhead costs. Alternatives are analyzed to address the profitability of specifically the flow controller product line and combat the declining margins, including adjusting the cost accounting method or changing the flow controller's pricing.
