It has been estimated that approximately 70% of the machine maintenance section's costs are incurred servicing the machine shop and the remainder incurred servicing the fitting section.
Required:
(a) (i) Calculate the following budgeted overhead absorption rates:
A machine hour rate for the machine shop.
A rate expressed as a percentage of direct wages for the fitting section.
All workings and assumptions should be clearly shown.
(ii) Calculate the budgeted manufacturing overhead cost per unit of product X.
(b) The production director of Bookdon PLC has suggested that 'as the actual over-heads incurred and units produced are usually different from the budgeted and as a consequence profits of each month end are distorted by over/under absorbed overheads, it would be more accurate to calculate the actual overhead cost per unit each month end by dividing the total number of all units actually produced during the month into the actual overheads incurred.'
Critically examine the production director's suggestion.
