Refer to Exercise 22-25. Assume that division A can sell the 1,000 units to other customers at $155 per unit, with variable marketing cost of $5 per unit.

Required 
Determine whether Allison-Chambers will benefit if division C purchases the 1,000 units from external suppliers at $135 per unit. Show your computations.

Data From Exercise 22-25:

The Allison-Chambers Corporation, manufacturer of tractors and other heavy farm equipment, is organized along decentralized product lines, with each manufacturing division operating as a separate profit center. Each division manager has been delegated full authority on all decisions involving the sale of that division’s output both to outsiders and to other divisions of Allison Chambers. Division C has in the past always purchased its requirement of a particular tractor-engine component from division A. However, when informed that division A is increasing its selling price to $150, division C’s manager decides to purchase the engine component from external suppliers.

Division C can purchase the component for $135 per unit in the open market. Division A insists that, because of the recent installation of some highly specialized equipment and the resulting high depreciation charges, it will not be able to earn an adequate return on its investment unless it raises its price. Division A’s manager appeals to top management of Allison-Chambers for support in the dispute with division C and supplies the following operating data:

                    

Required
1. Assume that there are no alternative uses for internal facilities of division A. Determine whether the company as a whole will benefit if division C purchases the component from external suppliers for $135 per unit. What should the transfer price for the component be set at so that division managers acting in their own divisions’ best interests take actions that are also in the best interest of the company as a whole?
2. Assume that internal facilities of division A would not otherwise be idle. By not producing the 1,000 units for division C, division A’s equipment and other facilities would be used for other production operations that would result in annual cash-operating savings of $18,000. Should division C purchase from external suppliers? Show your computations.
3. Assume that there are no alternative uses for division A’s internal facilities and that the price from outsiders drops $20. Should division C purchase from external suppliers? What should the transfer price for the component be set at so that division managers acting in their own divisions’ best interests take actions that are also in the best interest of the company as a whole?
