of sales beyond the split-off point is less than the incremental cost of further
processing.

1. Joint costs arise from the simultaneous processing or manufacturing of two or more
products made from the same process. These joint costs are not traceable to any
2. The dollar value of the finished-goods inventories on November 30 for products MJ-4
and HD-10 are calculated as follows:
MJ-4 HD-10

Inventory values on November 30:

Joint cost allocation ................................................. $1,800,000 $1,200,000
3. Wyalusing Chemicals should continue to process HD-10 beyond the split-off point,
since the incremental revenue is $1.00 greater per gallon than the incremental cost.
The joint cost is irrelevant to the decision because it will not change regardless of

$1.80
Incremental cost per gallon from further processing:
5. The director of research, Jack Turner, acted improperly in asking the assistant
controller to alter her analysis in favor of producing Compodalene. If he believes the
further processing of Compod is in Chemco’s best interests, he should try to back
up his claim with some projected cost reductions and the potential impact on the

PROBLEM 17-32 (CONTINUED)
6. It is preferable to sell Compod than to sell Compodalene, as the solution to
requirement (4) showed. Nevertheless, it is preferable to sell Compodalene than to
sell nothing, since each gallon of Compodalene makes a positive contribution
toward covering the joint production cost, fixed costs, and profit.
