2. (40 points) A company makes remotely controllable model airplane. The company has two divisions, D1 and D2. Division D1 makes airplane model kit. Division D2 assembles and configures model airplane. A new airplane model has been developed of which the company will sell for $160 each. Division D2 of the company has planned to produce 1,000 units of fully assembled model airplane using its idle capacity. The division can either purchase the model kit from Division D1 or purchase it from an outside supplier for $130. The company has a policy that internal transfers are priced at their fully allocated costs. Assume that the variable cost and allocated fixed cost for each airplane model kit at Division D1 are $75 and $25, respectively. Also assume that the assembling and administrative variable costs for each model airplane at Division D2 are $50 and $15, respectively. (1) Assume that Division D1 has idle capacity of producing the 1,000 sets of airplane model kit for Division 2. Should Division D2 purchase the airplane model kits from Division D1 (only consider D2 contribution margin)? Would the company as a whole benefit if Division D2 decides to purchase from Division D1 (consider company total contribution margin)? (2) Assume that Division D1 doesn't have any idle capacity and the required airplane model kits can be sold to outside customers for $115. Would the company as a whole benefit if Division D2 purchases the model kits from Division D1 (D1 contribution margin vs. company total contribution margin)? (3) Assume that the allocated fixed cost for each model airplane at Division D2 is $38. The 1,000 model planes are produced using the model kits from Division D1 for the company's EU sales division, which sells the model airplane for $225 each. Suppose the EU and US governments allow either the variable or fully allocated cost to be used as a transfer price. The US income tax is 35%, the EU income tax is 60%, and the import duty to EU is 15%. Which price should the company use to minimize the total of income taxes and import duties? Compute the saving from your choice of transfer price versus the other (compute total variable cost and total full cost first). (4) If EU has passed a new law decreasing the income tax rate to 50% and increasing the import duty to 20%, what would be the choice of transfer price in (3)?
