Johnson Tap Company is a manufacturer of taps and fittings for the plumbing trade, located in Brisbane. The Company was established by Ken Hall in 1951, with a workforce of 10, to meet the needs of the post-war housing boom. Its product range was fairly limited but the company had an excellent reputation for quality. Nowadays, CTC manufacturers an extensive range of high quality brass and chrome taps. The company is managed by Ken's son, Michael, and employs 20 people. It has annual sales averaging approximately $1million. Although it has been consistently profitable, CTC has experienced increasing pressure from competitors since the early 1990s. The company uses a cost-plus approach to pricing but is having to reduce its markup constantly in order to maintain market share. Both Ken and Michael qualified as engineers. The business is small and has never been able to employ an accountant. Instead, a bookkeeper calculates monthly profit as sales revenue minus expenses. Prices are based on rough estimates of cost of direct material and direct labour inputs plus a 50% markup. With the decline in profit and constant pressure on prices, Michael began to feel uneasy about the way costs and profits were calculated. The results for the month just ended were: Sales $980000 Less Expenses: Material Purchased$$300000 Factory Wages-Production line$$250000 Production Supervisor's Salary $35000 Rent $80000 Council Rates (Factory) $5000 Sales Staff$$110000 Advertising $18000 Equipment Depreciation $25000 Electricity $12000 Manager's Salary $80000 Truck Lease $10000 Total Expense $925000 Net Profit $55000 Additional Information: • The beginning inventory consists of: Raw material $40,000 work in process $60,000 finished goods $50,000 • At the end of the month, 20% of the materials purchased remained on hand, work in process amounted to 30% of the manufacturing costs incurred during the month, and finished goods inventories were $80,000. • The factory occupies 70% of the premises, the sales area 15% and administration 15%. • Most of the equipment is used for manufacturing, with only 10% of the book value being used for sales and administrative functions. • Almost all of the electricity is consumed in the factory. • The truck is used to deliver finished goods to customers. • Michael Hall spends about 40% of his time on factory management, 30% in the sales area and the rest on administration.
