Service Department Costing:
An Activity Approach
Solutions to Questions
15-1 Operating departments are the units in
an organization within which the central
pur-poses of the organization are carried out; these
departments usually generate revenue By
con-trast, service departments provide support or
assistance to the operating departments
Exam-ples of service departments include laundry
vices, internal auditing, airport maintenance
ser-vices (ground crews), cafeteria, personnel, cost
accounting, and so on
15-2 Service department costs are allocated
to products and services in two stages Service
department costs are first allocated to the
oper-ating departments These allocated costs are
then included in the operating departments’
overhead rates, which are used to cost products
and services
15-3 Interdepartmental service costs exist
whenever two service departments perform
ser-vices for each other Under the step method, the
costs of the service department performing the
greatest amount of service for the other service
departments are allocated first, the costs of the
service department performing the next greatest
amount of service are allocated next, and so
forth through all the service departments Once
a service department’s costs have been
allo-cated, costs are not reallocated back to it under
the step method
15-4 Under the direct method, costs are not
allocated from one service department to other Rather, all service department costs are allocated directly to operating departments
an-15-5 If a service department generates
reve-nues, these revenues should be offset against the department’s costs and only the net amount
of cost remaining after this offset should be cated to other departments
15-6 Two general guidelines govern the
allo-cation of fixed service department costs to other departments: (1) allocate only budgeted costs, and (2) allocate fixed costs in predetermined, lump-sum amounts, according to how much of the service department’s capacity is acquired to serve each of the other departments
Two general guidelines also govern the allocation of variable service department costs
to other departments: (1) allocate at budgeted rates, and (2) allocate the costs according to whatever activity (direct labor-hours, pounds of laundry, etc.) causes their incurrence
15-7 If a variable base is used to allocate
fixed costs, the costs allocated to one ment will depend in large part on what is hap- pening in other departments As a consequence, the amount of service department cost allocated
depart-to a department will increase or decrease pending on the activity in other departments

The manager of the Imperial Garden undoubtedly will be upset about the increased allocation of
fixed administrative expense Such an increased allocation may be viewed as a penalty for an
out-standing performance
3 Sales dollars is not ordinarily a good base for allocating fixed costs The departments with the
great-est sales will be allocated the greatgreat-est amount of cost and the costs allocated to a department will be
affected by the sales in other departments In our illustration above, the sales in two restaurants
re-mained static and the sales in the third increased As a result, less cost was allocated to the
restau-rants with static sales and more cost was allocated to the one restaurant that showed improvement
during the period

The variable costs are allocated by multiplying the budgeted rate per meal by the budgeted number of meals that will be served in each divi-sion during the month The fixed costs are allocated in predetermined, lump-sum amounts based on the peak-period need for meals in each di-vision
The variable costs are allocated according to the budgeted rate per meal and not according to the actual rate The fixed costs are again allocated
in predetermined, lump-sum amounts, based on budgeted fixed costs Any difference between budgeted and actual costs is not allocated, but rather is treated as a spending variance of the cafeteria:
Variable Fixed
Trang 16Problem 15-11 (continued)
One-half of the cost, or $85,000, would be allocated to each division, since an equal number of meals were served in each division during the month
4 This method has two major problems First, the spending variances should not be allocated, since this forces the inefficiencies of the service department onto the using departments Second, the fixed costs should not be allocated according to month-by-month usage of services, since this causes the allocation to one division to be affected by what happens
in another division
5 Their strategy probably will be to underestimate their peak period quirements in order to force a greater proportion of any allocation onto other departments Top management can control ploys of this type by careful follow-up, with rewards being given to those managers who es-timate accurately, and severe penalties assessed against those manag-ers who underestimate their peak period requirements For example, departments whose managers underestimate their peak period require-ments may be denied access to the cafeteria once their estimates have been exceeded
Trang 17re-Problem 15-12 (30 minutes)
1 Yes, there is merit to the complaint The company is using a variable base (hours of hangar use) to allocate costs that are largely fixed Thus, the amount of cost that is charged to a division during a given month will depend to a large extent on usage in other divisions A reduction in usage in one division can result in shifts of costs from it onto the other divisions, even though the other divisions receive no more service

1,000 hours Fixed cost per quarter:
Total cost, 1st quarter $172,000Less variable cost ($4 per hour × 3,000 hours) 12,000Fixed cost $160,000 Thus, the cost formula is $160,000 fixed cost plus $4 per hour variable cost
Trang 18Problem 15-12 (continued)
3 Even though the peak-period level of activity will not be reached until
the fourth quarter, it should still be used to allocate the fixed costs of
the hangar The reason is that peak-period requirements determine the present level of fixed costs The fact that the divisions do not need a
peak-period level of servicing every quarter is immaterial If the divisions require such servicing at certain times, then the capacity to deliver it
must be available, and it is the responsibility of the divisions to bear the cost of that capacity

$4 per hour × 900 hours $ 3,600
