7. Parkes Manufacturing has four categories of overhead. The four categories and the expected overhead
costs for each category for next year are as follows:
Maintenance
£300,000
Materials handling
150,000
Setups
200,000
Inspection
250,000
Currently, overhead is applied using a predetermined overhead rate based upon budgeted direct labour
hours. For next year, 100,000 direct labour hours are budgeted.
The company has been asked to submit a bid for a proposed job. The plant manager feels that
obtaining this job would result in new business in future years. Usually bids are based upon full
manufacturing cost plus 25 per cent.
Estimates for the proposed job are as follows:
Direct materials
£20,000
Direct labour (1,500 hours)
£15,000
Number of materials moves
20
Number of inspections
25
Number of setups
5
Number of machine hours

In the past, full manufacturing cost has been calculated by allocating overhead using a traditional
volume-based cost driver system--direct labour hours. The plant manager has heard of a new way of
applying overhead that uses cost pools and cost drivers.
Expected activity for the four activity-based cost drivers that would be used are as follows:
Machine hours
40,000
Material moves
8,000
Setups
10,000
Quality inspections
15,625
Required:
a.
Determine the amount of overhead that would be allocated to the proposed job if direct
labour hours are used as the cost driver.
Determine the total cost of the proposed job.
Determine the company's bid if the bid is based upon full manufacturing cost plus 25 per
cent.
b.
Determine the amount of overhead that would be applied to the proposed project if
activity-based costing is used.
Determine the total cost of the proposed job if activity-based costing is used.
Determine the company's bid if activity-based costing is used and the bid is based upon full
manufacturing cost plus 25 per cent.
c.
Which product costing method produces the more competitive bid?
8. Explain the differences between direct assignment, driver assignments, and cost allocations.
9. Describe several of the major differences between a traditional functional-based cost management
system and an activity-based cost management system.
10. In choosing a cost accounting system, the accountant must balance the total costs of implementing
such systems. What costs must be balanced to determine total cost? How do traditional
functional-based and activity-based cost systems balance the trade-offs?
11. Explain the advantage of using multiple overhead rates instead of a single plantwide overhead rate to
apply overhead.
12. Manchester Ltd. uses a job-order costing system and a predetermined overhead rate based on machine
hours.
At the beginning of the year, the company estimated manufacturing overhead for the year would be
£135,000 and 9,000 machine hours would be used.
