Serenity Now Industries manufactures custom fiberglass hulls for luxury yachts and
pleasure boats. The current cost accounting system uses machine hours to allocate
manufacturing overhead to each job. Serenity estimates that in the coming year it will
incur $600,000 in manufacturing overhead costs and use 8,000 machine hours.
Depending on the specifications requested by the customer, the hull may use hazardous
chemicals that incur greater disposal costs. Serenity’s traditional accounting system
includes the cost of hazardous waste disposal in with total manufacturing overhead.
Serenity is planning to implement an activity based costing system to more accurately
assign hazardous waste disposal costs to each job.
Expected usage and costs for manufacturing overhead are as follows:
During the year, Yacht #633 was started and completed:
Requirements:
a.Calculate the cost of Yacht #633 using the Serenity’s current method of allocating
manufacturing overhead.
b.Calculate the cost of Yacht #633 using the proposed activity based costing system.
How is this information useful to an environmental management accounting (EMA)
system?
