$7 500
$4 500
$30 500
The followings details were obtained from the accounts relating to the period.

Fire insurance 1 250
Power 4 500
Heating and lighting 2 000
Rates 1 800
Machine depreciation 8 400
Machine insurance 850
Canteen deficit 4 250
Balance of maintenance costs (exclu. Major works) 17 500
All apportionment follows a similar principle. For example, the total fire and machine insurance of $2 100 is divided by the total plant value of $447 000 which is then multiplied, in turn, by the value of the plant in each cost centres.
The secondary apportionment is carried out using a net plant value of $345 000 i.e. less the values in stores and maintenance.
The additional complications which can arise with Service Depts. are dealt with below.
Maintenance is apportioned on Plant Values because maintenance hours are not available for the service C.C.s which naturally must have some maintenance.
