A manufacturing company, Man Co, has two divisions: Division L and Division M. Both divisions make a single standardised product. Division L makes component L, which is supplied to both Division M and external customers.Division M makes product M using one unit of component L and other materials. It then sells the completedproduct M to external customers. To date, Division M has always bought component L from Division L.The following information is available:Division L charges the same price for component L to both Division M and external customers. However, it does not incur the selling and distribution costs when transferring internally.Division M has just been approached by a new supplier who has offered to supply it with component L for $37 per unit. Prior to this offer, the cheapest price which Division M could have bought component L for from outside the group was $42 per unit.It is head office policy to let the divisions operate autonomously without interference at all.Required:(a) Calculate the incremental profit/(loss) per component for the group if Division M accepts the new supplier’soffer and recommend how many components Division L should sell to Division M if group profits are to bemaximised. (3 marks)(b) Using the quantities calculated in (a) and the current transfer price, calculate the total annual profits of each division and the group as a whole. (6 marks)(c) Discuss the problems which will arise if the transfer price remains unchanged and advise the divisions on a suitable alternative transfer price for component L. (6 marks)
