Downeast Fisheries operates a fish processing plant. Fish is processed in batches of 10,000 kilograms. Processing fish yields three products: - fillets, which are sold fresh or quick-frozen - fish pieces, which are sold to another fish-products plant to be used in breaded fish cakes - offal (unused parts of the fish), which is transported to a fertilizer plant The following table summarizes the yield and financial characteristics of processing a batch of fish: Fresh fish can be quick-frozen with an associated separable processing and selling cost of $0.50 per kilogram; it is then sold for $5.50 per kilogram. Quick-freezing also incurs a fixed cost of $500 per batch. If the fresh fish is frozen, the $1.50 separable cost of processing the fresh fish would be avoided. Required: a) Should the fillets be sold as fresh fish or quick-frozen? a) Assume that the joint cost, which includes the cost of purchasing and processing the fish, is $7,000 per batch, and that the offal is treated as a by-product that is recognized at the split- off point. Allocate the joint cost to each of the products using: i) Physical output method ii) Net realizable value method iii) Constant gross margin percentage
