A company that manufactures baseballs begins operations on January 1. Each baseball
requires three elements: a hard plastic core, several yards of twine that are wrapped around the
plastic core, and a piece of leather to cover the baseball. The plastic core is started down a
conveyor belt and is automatically wrapped with the twine to the approximate size of the
baseball, at which time the leather cover is sewn to the wrapped twine. Finished baseballs are
inspected, and the ones that are defective due to internal production failure are pulled out.
Defective baseballs cannot be economically salvaged and are destroyed. Cost and production
reports for the first week of operations are:

the order with only 1,900 units instead of the quantity originally ordered. The spoiled units can be sold as
seconds for $25 each. Spoiled goods are kept in a separate inventory account from finished goods. Total

Spoilage With a Salvage Value in a Process Cost System Using an Average Cost Flow Assumption. Carter
Company manufactures a single product in two departments, Cutting and Finishing. Units of a product are
started in the Cutting Department and then transferred to the Finishing Department where they are
completed. Units are inspected at the 80% stage of completion in the Finishing Department. Good units
are transferred to finished goods inventory when completed and spoiled units are transferred to a separate
inventory account. Spoiled units are inventoried at their salvage value of $3 each, and the unrecoverable cost
of spoilage, which was caused by an internal failure, should be charged to the appropriate account.
Materials are added at the beginning of the production process. At the end of June, 2,000 units were
still in process in the Finishing Department, 100% complete as to materials and 60% complete as to
conversion costs. During July, 20,000 units were transferred from the Cutting Department to the Finishing
Department and 15,000 were transferred from the Finishing Department to finished goods inventory. At the
end of July, the Finishing Department still had 4,000 units in process, 100% complete as to materials and
20% complete as to conversion costs. Cost data related to July operations in the Finishing Department
follow:

Production Shrinkage in a Process Cost System Using an Average Cost Flow Assumption. Carrera
Chemical Inc. uses a process cost system with an average cost flow assumption to account for the production
of its only product. The product is manufactured in two departments. Units of product are started in the
Cooking Department and then transferred to the Blending Department where they are completed. Because
of the intense heat applied in the Cooking Department, some of the production volume is lost to evaporation.
Labor and overhead are treated as one element of cost in the Cooking Department (i.e., conversion cost).
Data related to May operations in the Cooking Department follow:
Units in beginning inventory .................................................................................................................
Units started in process this period ......................................................................................................
Units transferred to the Blending Department this period ................................................................
Units in ending inventory (100% materials, 40% conversion cost) ...................................................

Spoilage With a Salvage Value in a Process Cost System With a Fifo Cost Flow Assumption. School Craft
Petroleum Company uses a process cost system with a fifo cost flow assumption to account for production,
which is manufactured in two departments. Units of product are started in the Cracking Department and
then transferred to the Refining Department where they are completed. Units are inspected at the end of the
production process in the Refining Department. Good units are transferred to finished goods inventory and
spoiled units are transferred to a separate inventory account. Spoiled units are inventoried at their salvage
value of $8 each, and the unrecoverable cost of spoilage resulting from an internal production failure is
charged to the appropriate account. Data related to September operations in the Refining Department
follow:
Units in beginning inventory (60% materials, 30% labor, 30% overhead) ......................................
Units received from Cracking Department this period ......................................................................
Units transferred to the finished goods inventory this period ............................................................
Units transferred to special inventory account this period ................................................................
Units in ending inventory (100% materials, 50% labor, 50% overhead) .........................................
