The Stiefvater Company manufactures a variety of industrial valves and pipe fittings that are sold to customers in the region. Currently the company is operating at about 70 percent of capacity and is earning a satisfactory profit. Glascow Industries, Ltd., of Scotland has approached Stiefvater with an offer to buy 120,000 units of pressure valves. Glascow normally produces its own valves, but a fire in one of its plants has caused a temporary shortage. Glascow needs the 120,000 valves over the next four months to meet commitments to its regular customers. It is prepared to pay $ 19 for each valve. Stiefvater’s product cost for the pressure value is as follows:

Direct materials ........................................................ $ 5.00

Direct labor ............................................................... 6.00

Unit-related overhead .............................................. 6.00

Facility-sustaining overhead .................................... 7.00

Total cost ...................................................................$ 24.00

Additional costs incurred in connection with sales of the pressure valve include sales commissions of 5 percent (excluded for this order) and freight expense of $ 1.00 per unit. Stiefvater normally sells the pressure valves at a markup on unit-related manufacturing cost of 75 percent. Production management believes that it can handle the Glascow order without disrupting its scheduled production. The order would, however, require additional batch-related overhead of $ 12,000 per month. If management accepts this order, 30,000 pressure valves will be manufactured and shipped to Glascow each month for the next four months.
