Part 2 Continued
Notice how the unit gross profit figures change for parts 1 and 2. The
reason is the relatively large sales volumes for Premium and
Gourmet; sales value is used in part 2, with the effect of increasing
the joint cost allocated to these products and reducing the joint cost

2. In this case the net realizable value method should be preferred
because all Johnston’s production is processed further, and the NRV
method accounts for the additional processing costs. Note particularly, that
under the Sales Value at Split Off method, the gross margin for product

1. The relative sales value method of joint cost allocation assigns
cost in proportion to each product’s sales value to the sales value of
all products. If there is no sales value at split-off, then the value at
the first sales point less separable costs is used. If joint products
have a sales value at the split-off point, the margin for all joint
products at the split-off point will be the same.
As long as the total net realizable value of all joint products
exceeds the total production costs, all the products will be profitable
and the carrying value of the inventory will be less than the net
realizable value. Furthermore, the joint costs are allocated in
production costs.”
2. Because both main products have a market value at the split-off
point, this value is used to allocate the joint cost rather than the final
sales value.
Joint production costs to be allocated $2,640,000

would be proportionally allocated to all three products on the basis of
the sales value of each product at the split-off point. The net
