One of your Taiwanese suppliers has bid on a new line of molded plastic parts that is currently being assembled at your plant. The supplier has bid $0.10 per part, given a forecasted demand of 230,000 parts in year 1; 320,000 in year 2; and 490,000 in year 3. Shipping and handling of parts from the supplier's factory is estimated at $0.01 per unit. Additional inventory handling charges should amount to $0.005 per unit. Finally, administrative costs are estimated at $20 per month.

Although your plant is able to continue producing the part, the plant would need to invest in another molding machine, which would cost $13,000. Direct materials can be purchased for $0.08 per unit. Direct labor is estimated at $0.03 per unit plus a 50 percent surcharge for benefits; indirect labor is estimated at $0.013 per unit plus 50 percent benefits. Up-front engineering and design costs will amount to $35,000. Finally, management has insisted that overhead be allocated if the parts are made in-house at a rate of 100 percent of direct labor cost. The firm uses a cost of capital of 15 percent per year.
