Alternative methods of joint-cost allocation, product-mix decisions. The Southern Oil Company buys crude vegetable oil. Refining this oil results in four products at the splitoff point: A, B, C, and D. Product C is fully processed by the splitoff point. Products A, B, and D can individually be further refined into Super A, Super B, and Super D. In the most recent month (December), the output at the splitoff point was as follows: ? Product A 322,400 ? Product B 119,600 ? Product C 52,000 ? Product D 26,000 The joint costs of purchasing and processing the crude vegetable oil were $96,000. Southern had no beginning or ending inventories. Sales of product C in December were $24,000. Products A, B, and D were further refined and then sold. Data related to December are as follows: Joint Costs $96,000.00

Products A, B, and D can individually be further refined into Super A, Super B, and Super D. In the most recent month (December), the output at the split off point was as follows: Product A, 322,400 gallons Product B, 119,600 gallons Product C, 52,000 gallons Product D, 26,000 gallons The joint costs of purchasing and processing the crude vegetable oil were $96,000. Southern had no beginning or ending inventories. Sales of product C in December were S24.000. Products A, B, and D were further refined and then sold. Data related to December are as follows: Southern had the option of selling products A, B, and D at the split off point. This alternative would have yielded the following revenues for the December production: Product A, $84,000 Product B, $72,000 Product D, $60,000 Compute the gross-margin percentage for each product sold in December, using the following methods for allocating the $96,000 joint costs: Sales value at split off Physical-measure NRV Could Southern have increased its December operating income by making different decisions about the further processing of products A, B, or D?
