Port Allen Chemical Company processes raw material D into joint products E and F. Raw material D costs $4 per liter. It costs $100 to convert 100 liters of D into 60 liters of E and 40 liters of F. Product F can be sold immediately for $4 per liter or processed further into Product G at an additional cost of $3 per liter. Product G can then be sold for $9 per liter. a. Determine whether Product F should be sold or processed further into Product G.
b. Calculate the net advantage (disadvantage) of further processing.
c. Use a negative sign with your answer to indicate a net disadvantage (if applicable).

a) Product G should be produced and sold

b) Net financial advantage      $80

Explanation:

A company should process further a product if the additional revenue from the split-off point is greater than than the further processing cost.  

Also note that all cost incurred up to the split-off point are irrelevant to the decision to process further .  

                                                                                            $

Revenue after split-off point  

($9×  40 litres)                                                                 360

Revenue at the slit of point  

($4 ×   40)                                                                         (160)

Additional income from further processing                  200

Further processing cost ($3× 40)                                  (120)

Incremental income from further processing                 80

Incremental income from further processing = $80

a) The product F should be processed further and sold as product G. Doing so would increase the net income by $80.

b) Net advantage                                               $80
