AC designs and manufactures electronic components for use in sophisticated

equipment. These components have applications in the manufacture of weapons. There are two

manufacturing departments, X and Y, in the company. Department X carries out product design and

preparation of materials for the components. Department Y assembles and finishes the production

with highly automated machinery and equipment. Direct labour consists of designers in Department

X and skilled testers in Department Y. During the year 2012, direct labour cost is $80 per hour. The

company uses job-order costing and costs its products with normal costs. Factory overhead costs (FOH) are charged to the jobs with plant-wide application rate based on direct labour hours (DLH). Factory overheads under or over applied are closed to cost of goods sold at the end of each quarter.

AC bids for commercial jobs in through open tenders. In addition, AC takes on special assignment jobs from the Ministry of Defence. The company bills its customers only when jobs are

completed and delivered. For Ministry of Defence jobs, the government allows AC to bill at total

product costs for the jobs plus a 15% mark-up.
