Service companies that provide specific, nonroutine

services will probably benefit from using a job order

cost system.

Those that perform routine, repetitive services will

probably be better off with a process cost system.

SO 2 Explain the similarities and differences between job order cost and process cost systems.


Similarities and Differences Between Job Order Cost and Process Cost Systems

Job Order Cost

Costs assigned to each job.

Products have unique characteristics.

Process Cost

Costs tracked through a series of connected manufacturing processes or departments.

Products are uniform or relatively homogeneous and produced in a large volume.

Process Cost Flow

SO 3 Explain the flow of costs in a process cost system.

Illustration 3-5

Tyler Company manufactures automatic can openers that it sells to retail outlets. Manufacturing consists of two processes: machining and assembly. The Machining Department shapes, hones, and drills the raw materials. The Assembly Department assembles and packages the parts.

Page

3-16

Accumulation of materials, labor, and overhead costs is same as in job order costing.

Debit Raw Materials Inventory for purchases of raw materials.

Debit Factory Labor for factory labor incurred.

Debit Manufacturing Overhead for overhead cost incurred.

Assignment of the three manufacturing cost elements to Work in Process is different.


Assigning Manufacturing Costs

K Christel Company manufactures ZEBO

through two processes: blending and

bottling. In June, raw materials used were Blending $18,000

and Bottling $4,000. Factory labor costs were Blending

$12,000 and Bottling $5,000. Manufacturing overhead costs

were Blending $6,000 and Bottling $2,500. The company

transfers units completed at a cost of $19,000 in the

Blending Department to the Bottling Department. The

Bottling Department transfers units completed at a cost of

$11,000 to Finished Goods. Journalize the assignment of

Companies often use a combination of a process cost

and a job order cost system.

Called operations costing, this hybrid system is similar

to process costing in its assumption that standardized

methods are used to manufacture the product.

At the same time, the product may have some

customized, individual features that require the use of

a job order cost system.

Wal-Mart has 138 million weekly customers.

In 2006 Wal-Mart had annual sales of $312 billion and net

income of more than $11.2 billion.

There are about 5,300 Wal-Mart stores worldwide. During a

single recent year, it planned on adding 500 more stores,

and it believes that the U.S. has room for at least 4,000

more ―supercenters.‖

Page

3-55

During a recent year, 10,000 companies applied to be new

suppliers to Wal-Mart. Of those, some 200 (about 2%) were

accepted.

Wal-Mart doesn’t like to account for more than 30% of a

supplier’s total business for fear that changing an order can

destroy the supplier.

As shown in the ―About the Numbers‖ section in the next

column, Wal-Mart’s ―kingdom‖ spreads across many

different countries. Recently, however, it sold all of its

stores in Germany because they could not meet its desired

profitability goals.

Suppose that you were Colin Roche, whose PenAgain pen was

recently offered a 30-day trial period at 500 Wal-Mart

stores. In order for the product to pass the trial, in one

month Wal-Mart needs to sell 85% of the 48,000 pens that

it ordered. If it does, it will then order pens for a much

wider distribution at many more of its stores. If it doesn’t,

the deal is off. The PenAgain company gets between $6.49

and $12 from other retailers for the PenAgain pen, but Wal-

Mart is willing to pay only $3.76. Last year total sales of

PenAgain were $2,000,000.

If you were Colin Roche, would you accept Wal-Mart’s offer?

Page

3-58

If you were Colin Roche, would you accept Wal-Mart’s offer?

YES: Are you kidding? If only a tiny fraction of Wal-Mart customers buy a pen, the company’s sales will go through the roof. You have to take a shot at it.

NO: The risks are high on two counts. First, the company has to dramatically increase its operations in order to meet the production requirements. What will it do with this excess capacity if the deal falls through? Second, thecompany risks alienating the retailers that it currently supplies with pens. It could lose both Wal-Mart and its existing customers.

SO8 Compute equivalent units using the FIFO method.

Equivalent Units Under FIFO

Equivalent units are the sum of the work performed to:

1. Finish the units of beginning work in process

inventory.

2. Complete the units started into production during

the period (referred to as the units started and

completed).

3. Start, but only partially complete, the units in

ending work in process inventory.

FIFO and Weighted-Average

Weighted-average is simple to understand and apply.

In cases where prices do not fluctuate significantly,

weighted-average will be very similar to FIFO.

Conceptually, the FIFO method is superior because it

measures current performance using only costs

incurred in the current period.

FIFO method provides current cost information,

which the company can use to establish more accurate

pricing strategies for goods manufactured and sold.
