Q2: Process for Allocating Support
Department Costs
Clarify allocation purpose
if the purpose is to motivate the use of the services of a newly formed department, perhaps no costs should be allocated
if the purpose is to discourage operating department managers from over-use of the services of support departments, then a rate per unit of service might be large and not based on actual costs
if the purpose is to determine the full cost of products or services for long-term pricing decisions, then all support costs should be allocated

Q3: The Direct Method Example
Philco Toys makes metal and plastic toys in separate departments. It has two support departments, Accounting and Information Systems. Philco has decided to allocate Accounting department costs based on the number of employees in each department and Information Systems costs based on the number of computers in each department. Given the information below, use the direct method to allocate support department costs.

Q3: The Direct Method Example
Plastic Products is allocated 22/(22+16) of Accounting department costs, and Metal Products is allocated 16/(22+16). Notice that the number of employees in the support departments is ignored under the direct method.

Plastic and Metal Product share Info Systems costs equally because they have the same number of computers in each department. Notice that the number of computers in the support departments is ignored under the direct method.

Q4: The Step-Down Method of Allocating
Support Department Costs
The step-down method allocates some (but not all) support department costs to other support departments.
Allocation order must be determined.
The first support department’s costs are allocated to all operating and support departments that use its services.
Each subsequent support department’s costs are allocated to all operating and support departments that use its services, except any support department whose costs were already allocated.

Q4: The Step-Down Method Example
Given the information for Philco, use the step-down method to allocate support department costs. Allocate the costs of the support department that provides the largest percentage of its services to the other support department first.
First determine allocation order:
Accounting provided 4/(4+22+16) = 4/42 = 9.5% of its services to Info Systems.

Information Systems provided 4/(4+3+3) = 4/10 = 40% of its services to Accounting, so Information Systems goes first.

Q4: The Step-Down Method Example

Info Systems costs are allocated to Accounting, Plastic, & Metal based on each department’s number of computers compared to total non-Info Systems computers: 4+3+3=10.

Accounting costs are allocated only to Plastic & Metal based on each department’s number of employees compared to total non-Accounting and non-Info Systems employees: 22+16=38

Total costs allocated out of Accounting are now higher because of the Info Systems costs allocated to Accounting.

Q5: The Reciprocal Method of Allocating
Support Department Costs
The reciprocal method allocates all support department costs to other support departments.
The first step is to compute the total costs of each support department when its usage of other support department services is taken into consideration.
Support department costs are then allocated to all other operating and support departments that consume its services.

Slide # 22
Q5: The Reciprocal Method Example
Given the information for Philco, use the reciprocal method to allocate support department costs.
First determine total costs for each support department by writing an equation for its costs (use A and IS as abbreviations).
A = $48,000 + [4/(4+3+3)] x IS; IS = $72,000 + [4/(4+22+16)] x A
Then solve:
A = $48,000 + (4/10) x [$72,000 + (4/42) x A]

A = $48,000 + $28,800 + (16/420) x A]
(404/420) x A = $76,800
A = $76,800 x (420/404) = $79,842
IS = $72,000 + (4/42) x $79,842 = $79,604

The given information and the “First determine…” is automated (and it disappears on the first mouse click).
The first click brings in the A = $48,000 + …. text.
The second click brings in the rest of the solution; there is a 3 second delay for each row of the computation.

Support costs need to be considered when evaluating decisions such as make/buy, keep/drop, special order, and constrained resource
Necessary to isolate relevant support costs
This may not be the same as the allocated support costs
For example, outsourcing an operating department may not result in a reduction in support department costs

Q7: Decision Making with Support Costs

‹#›

Transfer prices should be set to motivate efficient use of the support department resources
If transfer price is set too high, user departments may outsource the service
If transfer price is set too low, user departments may utilize the support department inefficiently
The best transfer pricing approach is the Opportunity Cost approach
Each department is charged an amount that reflects the value of any opportunities forgone by not using the service for its next best alternative use.
This is often difficult in practice so most companies use a cost based or market based transfer pricing policy

Q7: Other Common Cost Allocation Methods
Under the stand-alone method, a common cost is allocated based on information about the users’ consumption of the cost.
Under the incremental cost allocation method, a “primary user” is allocated the bulk of the common cost and the secondary user is allocated only the increment in cost that it caused.
Other cost allocation purposes may require the allocation to
be perceived as “fair”
be based on the user’s “ability to bear” the cost

Q7: Stand-Alone versus Incremental Cost
Allocation Methods Example
Leslie has a job interview with Big Co. next month in New York City. Her plane ticket cost $300, and she will need to spend $125/night for 2 nights in a hotel. She estimates that she will spend $50 in cab fares and $50 for food. Big Co. has promised to reimburse her actual costs. After this trip was arranged, Small Co., also located in New York City, called her for an interview. If she interviews with Small Co. while she’s there, she will spend an additional $125 for another night at a hotel, and another estimated $40 in cab fares and food. Think of at least two ways to allocate Leslie’s travel costs using the stand-alone method. Discuss the merits of each.
1. Compute the total cost of the trip and divide it by 2, since there are 2 interviews.
2. Compute the total cost of the trip and allocate 2/3 of it to Big Co. and 1/3 to Small Co. since she is spending 2 of the 3 nights in NYC for the Big Co. interview.

Slide # 36
Q7: Stand-Alone versus Incremental Cost
Allocation Methods Example
Perform the calculations for your two versions of the cost allocation under the stand-alone method. Then allocate the travel costs using the incremental cost allocation method. Which is more appropriate? Why?
If shared equally, then this is $407.50 for each company; if Big Co. is allocated 2/3 of the cost then $543.33 is allocated to Big Co. and $271.67 is allocated to Small Co.
Estimated total costs:
Plane ticket $300
Hotel 375
Cab fares & food 140
Total $815

Under the incremental cost allocation method, Big Co. is most likely to be considered the primary user. Since Leslie’s budgeted travel costs were $300 + $250 + $50 + $50 = $650 before she was offered the Small Co. interview, Big Co. is allocated $650 and Small Co. is allocated $815 – $650 = $165.
