Flexible Security Devices (FSD) has introduced a just-in-time production process and is considering the adoption of lean accounting principles to support its new production philosophy. The company has two product lines: Mechanical Devices and Electronic Devices. Two individual products are made in each line. Product-line manufacturing overhead costs are traced directly to product lines, and then allocated to the two individual products in each line. The company’s traditional cost accounting system allocates all plant-level facility costs and some corporate overhead costs to individual products. The latest accounting report using traditional cost accounting methods included the following information (in thousands of dollars).

                            

FSD has determined that each of the two product lines represents a distinct value stream. It has also determined that out of the $200,000 ($50,000 + $40,000 + $80,000 + $30,000) plant-level facility costs, product A occupies 22% of the plant’s square footage, product B occupies 18%, product C occupies 36%, and product D occupies 14%. The remaining 10% of square footage is not being used. Finally, FSD has decided that direct material should be expensed in the period it is purchased, rather than when the material is used. According to purchasing records, direct material purchase costs during the period were as follows:
