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: Fillets Pieces Offal Yield (kilograms) 2,100 1,500 6,800 Revenue (disposal cost) per kilogram $7.00 $3.50 ($0.30) Separable processing and selling cost per kilogram $2.00 $1.50 - Fresh fish can be quick-frozen with an associated separable processing and selling cost of $1.00 per kilogram; it is then sold for $6.50 per kilogram. Quick-freezing also incurs a fixed cost of $600 per batch. If the fresh fish is frozen, the $2.00 separable cost of processing the fresh fish would be avoided. Required: a) Should the fillets be sold as fresh fish or quick-frozen? b) Assume that the joint cost, which includes the cost of purchasing and processing the fish, is $7,500 per batch, and that the offal is treated as a by-product that is recognized at the splitoff 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
