16-1 Exhibit 16-1 presents many examples of joint products from four different general
industries. These include:
16-2 A joint cost is a cost of a production process that yields multiple products simultaneously.
16-3 The distinction between a joint product and a byproduct is based on relative sales value.
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
16-5 The chapter lists the following six reasons for allocating joint costs:
2. Computation of inventoriable costs and cost of goods sold for internal reporting purposes.
4. Insurance settlement computations for damage claims made on the basis of cost
information of joint products or byproducts.
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
16-7 This situation can occur when a production process yields separable outputs at the splitoff
16-2
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
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
16-10 The NRV method can be simplified by assuming (a) a standard set of post-splitoff point
16-11 The constant gross-margin percentage NRV method takes account of the post-splitoff
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
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.
16-14 Two methods to account for byproducts are:
16-15 The sales byproduct method enables a manager to time the sale of byproducts to affect

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 Chickens decision to process

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
