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

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.

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

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

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.
