2 The Information Technology division (IT) of the RJ Business Consulting Group provides consulting services to itsclients as well as to other divisions within the group. Consultants always work in teams of two on every consultingday. Each consulting day is charged to external clients at ￡750 which represents cost plus 150% profit mark up. Thetotal cost per consulting day has been estimated as being 80% variable and 20% fixed.The director of the Human Resources (HR) division of RJ Business Consulting Group has requested the services oftwo teams of consultants from the IT division on five days per week for a period of 48 weeks, and has suggested thatshe meets with the director of the IT division in order to negotiate a transfer price. The director of the IT division hasresponded by stating that he is aware of the limitations of using negotiated transfer prices and intends to charge theHR division ￡750 per consulting day.The IT division always uses ‘state of the art’ video-conferencing equipment on all internal consultations which wouldreduce the variable costs by ￡50 per consulting day. Note: this equipment can only be used when providing internalconsultations.Required:(a) Calculate and discuss the transfer prices per consulting day at which the IT division should provideconsulting services to the HR division in order to ensure that the profit of the RJ Business Consulting Groupis maximised in each of the following situations:(i) Every pair of consultants in the IT division is 100% utilised during the required 48-week period inproviding consulting services to external clients, i.e. there is no spare capacity.(ii) There is one team of consultants who, being free from other commitments, would be available toundertake the provision of services to the HR division during the required 48-week period. All otherteams of consultants would be 100% utilised in providing consulting services to external clients.(iii) A major client has offered to pay the IT division ￡264,000 for the services of two teams of consultantsduring the required 48-week period.(12 marks)

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)
