Alternative methods of joint-cost allocation, product-mix decisions. The Sunshine Oil Company buys crude vegetable oil. Refining this oil results in four products at the splitoft 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 0. In the most recent month (December), the output at the splitoff point was;

Product A, 300,000 gallons

Product B, 100,000 gallons

Product C, 50,000 gallons

Product D, 50,000 gallons

The joint costs of purchasing and processing the crude vegetable oil were $100,000. Sunshine had no beginning or ending inventories. Sales of product C in December were $50,000. Products A, B, and D were further refined and then sold. Data related to December are:

Sunshine had the option of selling products A, B, and D at the splitoff point This alternative would have yielded the following revenues for the December production;

Product A, $50,000

Product B, $30,000

Product D, $70,000

1. Compute the gross-margin percentage for each product sold in December, using the following methods for allocating the $100,000 joint costs;

a. Sales value at splitoff

b. Physical-measure

c. NRV

2. Could Sunshine have increased its December operating income by making different decisions about the further processing of products A, B, or D? Show the effect on operating income of any changes yourecommend.
