REVIEW OF LEARNING OBJECTIVES
1. Describe and illustrate the following costs: direct and indirect, direct materials, direct
labor, factory overhead, and product and period costs.
Manufacturing companies use machinery and labor to convert materials into a finished
product. A direct cost can be traced to a finished product, while an indirect cost cannot. The
cost of a finished product is made up of three components: (a) the cost of materials that are
directly identifiable with the final product, (b) the wages of employees that directly convert
materials to a finished product, and (c) costs incurred in the manufacturing process other
than direct materials and direct labor. These three manufacturing costs can be categorized
into prime costs (direct materials and direct labor) or conversion costs (direct labor and
factory overhead). Product costs consists of the elements of manufacturing cost – direct
materials, direct labor, and factory overhead – while period costs consist of selling and
administrative expenses.
2. Describe accounting systems used by manufacturing businesses.
A cost accounting system accumulates product costs. Management uses cost accounting
systems to determine the product cost, establish product prices, control operations, and
develop financial statements. The two primary cost accounting systems are job order and
process cost systems. Job order cost systems accumulate costs for each quantity of product
that passes through the factory. Process cost systems accumulate costs for each department
or process within the factory.
3. Describe and prepare summary journal entries for a job order cost accounting system.
A job order cost system accumulates costs for each quantity of product, or “job,” that passes
through the factory. Direct materials, direct labor, and factory overhead are accumulated on
the job cost sheet, which is the subsidiary cost ledger for each job. Direct materials and direct
labor are assigned to individual jobs based on the quantity used. Factory overhead costs are
assigned to each job based on an activity base that reflects the use of factory overhead costs.
Work in Process Inventory is the controlling account for the cost ledger. As a job is finished,
its costs are transferred to the finished goods ledger, for which Finished Goods Inventory is
the controlling account. When goods are sold, the cost is transferred from finished goods
inventory to Cost of Goods Sold.
4. Describe and illustrate the statement of cost of goods sold, statement of comprehensive
income, and statement of financial position for a manufacturing business.
The financial statements of manufacturing companies differ from those of merchandising
companies. Manufacturing company statement of financial position reports three types of
inventory: raw materials, work in process, and finished goods. The statement of
comprehensive income of manufacturing company reports cost of goods sold, which is the
total manufacturing cost of goods sold. The statement of comprehensive income is
supported by the schedule of cost of goods manufactured, which provides the details of the
cost of goods manufactured during the period.
5. Use job order cost information for decision making.
Job order cost systems can be used to evaluate cost performance. Unit costs can be compared
over time to determine if product costs are staying within expected ranges. Job order cost
information can support pricing and cost analysis. Managers can use job cost information to
identify unusual trends and areas for cost improvement.

6. Accounting for scrap, waste, spoilage and rework.
Most companies today are justifiably concerned about product quality. To a great extent the
current concern is the result of increased competition, particularly competition from abroad.
Many manufacturers, recognizing the need to improve efficiency and reduce costs, have
changed the emphasis of their businesses to continuous quality improvement and those that
succeed are becoming world-class manufacturers. Production losses in a job order cost
system include the cost of materials scrap, spoiled goods (spoilage), and reworking defective
goods. For the most part, these losses result from a lack of quality and should be eliminated
if possible. One way to call attention to the need for reducing these types of quality failures
is to determine their costs and then report these costs to top management. Large costs signal
an opportunity to improve quality substantially, which should be interpreted by management
as an opportunity to improve profits.
7. Backflush costing system ( Just-in-Time system).
Backflush costing is a streamlined cost accounting method that speeds up, simplifies, and
minimizes accounting effort in an environment that minimizes inventory balances, requires
few allocations, uses standard costs, and has minimal variances from standard. During the
period, this costing method records purchases of raw material and accumulates actual
conversion costs. Then, at a predetermined trigger point such as (a) at completion of
production, or (b) on the sale of goods, an entry is made to allocate the total costs incurred
to Cost of Goods Sold and to Finished Goods Inventory using standard production costs. The
four alternatives to the entries are: First, if production time were extremely short,
completion of the finished goods is the trigger point. Second, if goods were shipped
immediately to customers on completion, sale of the product is the trigger point. The third
alternative reflects the ultimate JIT system, sale of the product is the trigger point. A fourth
alternative charges all costs to the Cost of Goods Sold account, with a subsequent backflush
of costs to the Raw and In Process Inventory and the Finished Goods Inventory accounts at
the end of the period, sale of the product is the trigger point.
Contrast just-in-time processing with conventional manufacturing practices.
The just-in-time processing philosophy focuses on reducing time, cost, and poor quality
within the process. This is accomplished by combining process functions into work centers,
assigning overhead services directly to the cells, involving the employees in process
improvement efforts, eliminating wasteful activities, and reducing the amount of work in
process inventory required to fulfill production targets. It complements the other materials
planning and control tools, such as EOQ and safety stock calculations. Implementation of the
just-in-time philosophy can cause significant cost reductions and productivity improvements.
But, even within a single company, all inventory situations do not necessarily have to be on a
just-in-time system. The costs and benefits of any inventory control system must be
evaluated before management should consider installing the system. The use of JIT,
however, does allow workers as well as managers to concentrate on providing quality service
to customers.
8. Describe Activity-Based-Costing and why a number of companies are using this product
costing approach.
Activity-based costing is a method of accumulating and allocating factory overhead costs to
products, using many overhead rates. Each rate is related to separate factory activities, such
as inspecting, moving, and machining. Activity-based costing may be useful in making
product pricing decisions where manufacturing operations involve large amounts of factory
overhead. In such cases, traditional overhead allocation using bases such as direct labor cost
or direct labor hours may yield inaccurate cost allocations. This, in turn, may result in
distorted product costs and product prices. By providing more accurate product cost
allocations, activity-based costing aids in setting product prices that will cover costs and
expenses.

Job Order Costing (Accounting for scrap, waste, spoilage and rework)
21. MJ Company manufactures picture frames of all sizes and shapes and uses a job order
costing system. There is always some spoilage in each production run. The following costs
relate to the current run: Estimated overhead (exclusive of spoilage) P160,000; Spoilage
(estimated) P25,000; Sales value of spoiled frames P11,500; Labor hours 100,000 hours.
The actual cost of a spoiled picture frame is P7.00. During the year 170 frames are
considered spoiled. Each spoiled frame can be sold for P4. The spoilage is considered a
part of all jobs. Labor hours are used to determine the predetermined overhead rate.
