The two divisions of SBU Limited, P (producing) and B (buying), that are treated as investment centres for performance-evaluation purposes. As the management accountant, you have been asked to provide input to the determination of the appropriate transfer price for an exchange of product between these two divisions. The incremental production cost incurred by Division P, to the point of transfer, is $80 per unit. Division P can sell its output externally for $120 per unit, less a sales commission charge of $5 per unit. Currently, Division B is purchasing the product from an external supplier at $120 per unit, plus a $3 transportation charge per unit. Required: (a) (i) Assume that Division P has limited capacity. Thus, for each unit it sells internally, it loses the opportunity to sell that unit externally. Use the general transfer-pricing rule to determine the minimum transfer price for internal transfers of units, that Division P would charge Division B. From the standpoint of Division P, why is the figure you calculated considered an acceptable transfer price? (2 marks) (ii) What is the maximum transfer price that Division B would be willing to pay per unit on any internal transfers? (2 marks) (iii) If top management of the company allows the managers of Divisions P and B to negotiate a transfer price, what is the likely range of possible transfer prices? (2 marks) (b) (i) Assume now that Division P has excess capacity. Use the general transfer-pricing rule to determine the minimum transfer price that Division P would be willing to accept from Division B for any internal transfers. Would this transfer price motivate the correct economic decision (internal versus external transfer) from the standpoint of the company as a whole? Explain. (3 marks) (ii) Given the situation described above in (b)(i), would top management of the company want the transfer to take place internally? Why? (Show calculations, if appropriate.) How could top management ensure that an internal transfer would take place? (7 marks)
