CHAPTER 16
COST ALLOCATION: JOINT PRODUCTS AND BYPRODUCTS
16-1 Exhibit 16-1 presents many examples of joint products from four different general
industries. These include:
Industry Separable Products at the Splitoff Point
Food Processing:
• Lamb Lamb cuts, tripe, hides, bones, fat
• Turkey • Breasts, wings, thighs, poultry meal
Extractive:
• Petroleum • Crude oil, natural gas
16-2 A joint cost is a cost of a production process that yields multiple products simultaneously.
A separable cost is a cost incurred beyond the splitoff point that is assignable to each of the specific
products identified at the splitoff point.
16-3 The distinction between a joint product and a byproduct is based on relative sales value. A
joint product is a product from a joint production process (a process that yields two or more
products) that has a relatively high total sales value. A byproduct is a product that has a relatively
low total sales value compared to the total sales value of the joint (or main) products.
16-4 A product is any output that has a positive sales value (or an output that enables a company
to avoid incurring costs). In some joint-cost settings, outputs can occur that do not have a positive
sales value. The offshore processing of hydrocarbons yields water that is recycled back into the
ocean as well as yielding oil and gas. The processing of mineral ore to yield gold and silver also
yields dirt as an output, which is recycled back into the ground.
16-5 The chapter lists the following six reasons for allocating joint costs:
1. Computation of inventoriable costs and cost of goods sold for financial accounting
purposes and reports for income tax authorities.
2. Computation of inventoriable costs and cost of goods sold for internal reporting purposes.
3. Cost reimbursement under contracts when only a portion of a businesss products or
services is sold or delivered under cost-plus contracts.
4. Insurance settlement computations for damage claims made on the basis of cost
information of joint products or byproducts.
5. Rate regulation when one or more of the jointly produced products or services are subject
to price regulation.
6. Litigation in which costs of joint products are key inputs.
16-6 The joint production process yields individual products that are either sold this period or
held as inventory to be sold in subsequent periods. Hence, the joint costs need to be allocated
between total production rather than just those sold this period.
page-pf2
16-2
16-7 This situation can occur when a production process yields separable outputs at the splitoff
point that do not have selling prices available until further processing. The result is that selling
prices are not available at the splitoff point to use the sales value at splitoff method. Examples
include processing in integrated pulp and paper companies and in petro-chemical operations.
16-8 Both methods use market selling-price data in allocating joint costs, but they differ in which
sales-price data they use. The sales value at splitoff method allocates joint costs to joint products
on the basis of the relative total sales value at the splitoff point of the total production of these
products during the accounting period. The net realizable value method allocates joint costs to
joint products on the basis of the relative net realizable value (the final sales value minus the
separable costs of production and marketing) of the total production of the joint products during
the accounting period.
16-9 Limitations of the physical measure method of joint-cost allocation include:
a. The physical weights used for allocating joint costs may have no relationship to the
revenue-producing power of the individual products.
b. The joint products may not have a common physical denominator––for example, one
may be a liquid while another a solid with no readily available conversion factor.
16-10 The NRV method can be simplified by assuming (a) a standard set of post-splitoff point
processing steps and (b) a standard set of selling prices. The use of (a) and (b) achieves the same
benefits that the use of standard costs does in costing systems.
16-11 The constant gross-margin percentage NRV method takes account of the post-splitoff point
“profit” contribution earned on individual products, as well as joint costs, when making cost
assignments to joint products. In contrast, the sales value at splitoff point and the NRV methods
allocate only the joint costs to the individual products.
16-12 No. Any method used to allocate joint costs to individual products that is applicable to the
problem of joint product-cost allocation should not be used for management decisions regarding
whether a product should be sold or processed further. When a product is an inherent result of a
joint process, the decision to process further should not be influenced by either the size of the total
joint costs or by the portion of the joint costs assigned to particular products. Joint costs are
irrelevant for these decisions. The only relevant items for these decisions are the incremental
revenue and the incremental costs beyond the splitoff point.
16-13 No. The only relevant items are incremental revenues and incremental costs when making
decisions about selling products at the splitoff point or processing them further. Separable costs
are not always identical to incremental costs. Separable costs are costs incurred beyond the splitoff
point that are assignable to individual products. Some separable costs may not be incremental costs
in a specific setting (e.g., allocated manufacturing overhead for post-splitoff processing that
includes depreciation).
16-14 Two methods to account for byproducts are:
a. Production methodrecognizes byproducts in the financial statements at the time
production is completed.
b. Sales methoddelays recognition of byproducts until the time of sale.
page-pf3
16-3
16-15 The sales byproduct method enables a manager to time the sale of byproducts to affect
reported operating income. A manager who was below the targeted operating income could adopt
a fire-sale approach to selling byproducts so that the reported operating income exceeds the
target. This illustrates one dysfunctional aspect of the sales method for byproducts.
16-16 (20-30 min.) Joint-cost allocation, insurance settlement.
Quality Chicken grows and processes chickens. Each chicken is disassembled into five main parts.
Information pertaining to production in July 2014 is as follows:
Joint cost of production in July 2014 was $50.
A special shipment of 40 pounds of breasts and 15 pounds of wings has been destroyed in a
fire. Quality Chicken’s insurance policy provides reimbursement for the cost of the items
destroyed. The insurance company permits Quality Chicken to use a joint-cost-allocation method.
The splitoff point is assumed to be at the end of the production process.
Required:
1. Compute the cost of the special shipment destroyed using the following:
a. Sales value at splitoff method
b. Physical-measure method (pounds of finished product)
2. What joint-cost-allocation method would you recommend Quality Chicken use? Explain.

2. The sales value at splitoff method captures the benefits-received criterion of cost allocation
and is the preferred method. The costs of processing a chicken are allocated to products in
proportion to the ability to contribute revenue. Quality Chicken’s decision to process chicken is
heavily influenced by the revenues from breasts and thighs. The bones provide relatively few
benefits to Quality Chicken despite their high physical volume.
The physical measures method shows profits on breasts and thighs and losses on bones and
feathers. Given that Quality Chicken has to jointly process all the chicken products, it is non-
intuitive to single out individual products that are being processed simultaneously as making losses
while the overall operations make a profit. Quality Chicken is processing chicken mainly for
breasts and thighs and not for wings, bones, and feathers, while the physical measure method
allocates a disproportionate amount of costs to wings, bones, and feathers.
16-17 (10 min.) Joint products and byproducts (continuation of 16-16).
Quality Chicken is computing the ending inventory values for its July 31, 2014, balance sheet.
Ending inventory amounts on July 31 are 15 pounds of breasts, 4 pounds of wings, 6 pounds of
thighs, 5 pounds of bones, and 2 pounds of feathers.
Quality Chicken’s management wants to use the sales value at splitoff method. However,
management wants you to explore the effect on ending inventory values of classifying one or more
products as a byproduct rather than a joint product.
Required:
1. Assume Quality Chicken classifies all five products as joint products. What are the ending
inventory values of each product on July 31, 2014?
2. Assume Quality Chicken uses the production method of accounting for byproducts. What are
the ending inventory values for each joint product on July 31, 2014, assuming breasts and
thighs are the joint products and wings, bones, and feathers are byproducts?
3. Comment on differences in the results in requirements 1 and 2.

3. Treating all products as joint products does not require judgments as to whether a product
is a joint product or a byproduct. Joint costs are allocated in a consistent manner to all products for
the purpose of costing and inventory valuation. In contrast, the approach in requirement 2 lowers
the joint cost by the amount of byproduct net realizable values and results in inventory values
being shown for only two of the five products, the ones (perhaps arbitrarily) designated as being
joint products.
16-18 (10 min.) Net realizable value method.
Stenback Company is one of the world’s leading corn refiners. It produces two joint products—
corn syrup and corn starchusing a common production process. In July 2014, Stenback reported
the following production and selling-price information:

16-19 (40 min.) Alternative joint-cost-allocation methods, further-process decision.
The Wood Spirits Company produces two productsturpentine and methanol (wood alcohol)
by a joint process. Joint costs amount to $120,000 per batch of output. Each batch totals 10,000
gallons: 25% methanol and 75% turpentine. Both products are processed further without gain or
loss in volume. Separable processing costs are methanol, $3 per gallon, and turpentine, $2 per
gallon. Methanol sells for $21 per gallon. Turpentine sells for $14 per gallon.
Required:
1. How much of the joint costs per batch will be allocated to turpentine and to methanol, assuming
that joint costs are allocated based on the number of gallons at splitoff point?
2. If joint costs are allocated on an NRV basis, how much of the joint costs will be allocated to
turpentine and to methanol?
3. Prepare product-line income statements per batch for requirements 1 and 2. Assume no
beginning or ending inventories.
4. The company has discovered an additional process by which the methanol (wood alcohol) can
be made into a pleasant-tasting alcoholic beverage. The selling price of this beverage would
be $60 a gallon. Additional processing would increase separable costs $9 per gallon (in
addition to the $3 per gallon separable cost required to yield methanol). The company would
have to pay excise taxes of 20% on the selling price of the beverage. Assuming no other
changes in cost, what is the joint cost applicable to the wood alcohol (using the NRV method)?
Should the company produce the alcoholic beverage? Show your computations.
