Marine Components produces parts for airplanes and ships

Marine Components produces parts for airplanes and ships. The parts are produced to specification by their customers, who pay either a fixed price (the price does not depend directly on the cost of the job) or price equal to recorded cost plus a fixed fee (cost plus). For the upcoming year (year 2), Marine expects only two clients (client 1 and client 2). The work done for client 1 will all be done under fixed-price contracts while the work done for client 2 will all be done under cost-plus contracts.

Manufacturing overhead for year 2 is estimated to be $10 million. Other budgeted data for year 2 include:

Client 1 Client 2

Machine hours (thousands) 2,000 2,000

Direct labor cost ($000) 2,500 7,500
