the internal transfer will be in the best interests of the entity as a whole,
because it will help to maximise its total profit.
(b) When Division X has spare capacity, its only cost in making and selling extra
units of Product B is the variable cost per unit of production, $48. Division Y
can buy the product from an external supplier for $55.
It follows that a transfer that is higher than $48 but lower than $55, for
additional units of production, will benefit both profit centres as well as the
company as a whole. (It is in the best interests of the company to make the
units in Division X at a cost of $48 than to buy them externally for $55.)
(c) When Division X is operating at full capacity and has unsatisfied external
demand for Product A, it has an opportunity cost if it makes Product B for
transfer to Division Y. Product A earns a contribution of $16 per unit ($62 –
$46). The minimum transfer price that it would require for Product B is:
$
Variable cost of production of Product B 48
Opportunity cost: lost contribution from sale of Product A
16
Minimum transfer price to satisfy Division X management
64
Division Y can buy the product from an external supplier for $55, and will not
want to buy from Division X at a price of $64. The maximum price it will want
to pay is $55.
The company as a whole will benefit if Division X makes and sells Product A.
It makes a contribution of $16 from each unit of Product A.
If Division X were to make and sell Product B, the company would benefit
by only $7. This is the difference in the cost of making the product in
Division X ($48) and the cost of buying it externally ($55).
The same quantity of limited resources (direct labour in Division X) is needed
for each product, therefore the company benefits by $9 ($16 – $7) from making
units of Product A instead of units of Product B.
On the basis of this information, the transfer price for Product X should be $64
as long as there is unsatisfied demand for Product A. At this price, there will
be no transfers of Product B.
41 Training company
(a) If the Liverpool centre has spare capacity, it will be in the best interest of the
company for the London centre to use Liverpool trainers, at a variable cost of
£450 per day including travel and accommodation, instead of hiring external
trainers at a cost of £1,200.
Since the Liverpool centre will have to pay £450 per trainer day, any transfer
price per day/daily fee in excess of £450 would add to its profit.
Since the London centre can obtain external trainers for £1,200 per day, any
transfer price below this amount would add to its profit.
