The Marshall Company has a joint production process that produces two joint products and a by-product. The joint products are Ying and Yang, and the by-product is Bit. Marshall accounts for the costs of its products using the net realizable value method. The two joint products are processed beyond the split-off point, incurring separable processing costs.
