Soma Corporation is a multi-divisional company whose managers have been delegated full profit responsibility and complete autonomy to accept or reject transfers from other divisions. Division X produces 2,000 units of a subassembly that has a ready market. One of these subassemblies is currently used by Division Y for each final product manufactured, the latter of which is sold to outsiders for $1,600. Y's sales during the current period amounted to 2,000 completed units. Division X charges Division Y the $1,100 market price for the subassembly; Division Y has additional variable costs of $600 per unit. Variable costs for Division X are $850 per unit.
The manager of Division Y feels that X should transfer the subassembly at a lower price because Y is currently unable to make a profit.

Required:
A. Calculate the contribution margins (total dollars and per unit) of Divisions X and Y, as well as the company as a whole, if transfers are made at market price.
B. Assume that conditions have changed and X can sell only 1,000 units in the market at $900 per unit. From the company's perspective, should X transfer all 2,000 units to Y or sell 1,000 in the market and transfer the remainder? Note: Y's sales would decrease to 1,000 units if the latter alternative is pursued.
