Cost allocation: what it means
Some production centers or departments provide output required by other production centers (Service departments).The costs of these departments are allocated to the internal users according to use and add to their costsso the costs of service departments providing these products and services go indirectly into the cost of saleable outputService department‘s costs are allocated using the actual utilization volume times an allocation rate per unit

Allocating Support Departments CostsAn operating department (a production department in manufacturing companies) adds value to a product or serviceA support department (service department) provides the services that assist other operating and support departments in the organization.

Single-Rate and Dual-Rate Methods
The single-rate cost allocation method pools together all costs in a cost pool.The dual-rate cost allocation method classifies costs in each cost pool into two cost pools
a variable-cost cost pool and a fixed-cost cost pool
Organizations commit to infrastructure costs on the basis of a long-run planning horizon.Budgeted rates let the user department know in advance the cost rates they will be charged
During the budget period, the supplier department, not the user departments, bears the risk of any unfavorable cost variances.When actual rates are used for cost allocation, managers do not know the rates to be used until the end of the budget periodThe use of budgeted usage to allocate these fixed costs is consistent with the long-run horizon.

Allocating Support Departments Costs
Direct method:Allocates support department costs to operatingdepartments only.
Step-down (sequential allocation) method:Allocates support department costs to other supportdepartments and to operating departmentscharge rates are calculated for support departments according to a rank order. Those departments rank highest that get the least from other departmentsat each step support is charged only from the departments whose charge rate has already been calculated
Reciprocal allocation method:Allocates costs by services provided among all support departmentssimultaneous equations approach

Example
The Canton Division of Smith Corporation has twooperating departments
Assembly and Finishingand two support departments
Maintenance• allocated using square feet.• Total square feet = 255,000
Human Resources• allocated using number of employees• Total number of employees = 95

Step-Down Method
Which support department should be allocated first?Maintenance provides 12% of its services to Human Resources.Human Resources provides 10% of its services to Maintenance.
Maintenance to Human Resources:12% × $300,000 = $36,000
Maintenance to Assembly: 44% × $300,000 = $132,000Maintenance to Finishing: 44% × $300,000 = $132,000
Human Resources costs to be allocated become$2,160,000 + $36,000 = $2,196,000
Human Resources to Assembly: 48 ÷ 72 × $2,196,000 = $1,464,000
Human Resources to Finishing: 24 ÷ 72 × $2,196,000 = $732,000

Why the matrix calculus is useful
The numerical data required are provided in the accounting data base and can automaticallydownloaded into the matrix A and a vector of traceable unit costs kP.Spreadsheet software usually offers the function of matrix inversion
For larger problems an LP algorithm may be usedso the cost driver rates can be determined automatically.
18
Interpretation of R:=(I − A)-1
Consider the equation for required total output of service i as a function of external requirements y:
xi (y) = Σj rij yj
Differentiate this function w.r.t. yj . You get:
= rij
This means: rij represents the additional total output of service i required per additional unit of external output requirement of service j.Therefore the matrix R is sometimes called the total requirements matrix)
∂ xi (y) ∂ yj
19
Interpretation of R:=(I − A)-1
In particular:If you purchase one unit of the service i externally (reduce external demand by one unit)then you need rii units less to be procured internally.
Or, in other words: if you reduce internal procurement of the service by one unit, you need to buy only 1/ riiunits from external sources. Since the function xi (y) is linear, this is globally true.
20
Interpretation of R:=(I − A)-1
This means:If you close down service center i then you
can save the total reciprocal cost πi xi for this center butneed xi/rii units of the service externally
You will break even if the external procurement price pi satisfies:
pi xi / rii= pi xii.e. you may pay at most an external price of
pi = πi rii
21
Interpretation of RT := (I − AT)-1
So we get the reciprocal cost per unit as a function of the traceable cost:
cj (kP) = Σi kiP rij
Similarly to the above: = rij∂ cj (kP)
∂ kiP
22
Reciprocal method: Extension
Dual rate system for assigning committed costs: Peak load pricing
Assigning • committed cost according to capacity reservations by
users• flexible cost according to actual usage
if a service is outsourced: the reciprocal method shows the effect of cost drivers on required total volume (capacity) for all service departments
23
Allocating Common Costs
Two methods for allocating common cost1. Stand-alone cost allocation method
actual cost is allocated in the ratio of stand-alone costs2. Incremental cost allocation method
a sequence of cost objects is definedeach object bears the incremental cost according to the sequence
3. Shapley Valuethe average of incremental costs over all possible sequences is charged to the objectthe Shapley Value can be justified based on a set of plausible axioms
An Example
Three divisions (1,2,3) in an organization need typing services
Let K(i,...,j) denote the cost for the typing service when divisions (i,...,j) pool their typing services.Cost for stand-alone provision of typing K(1) = 10; K(2) = 20; K(3) = 30Costs with pooled typing services K(1,2) = 25; K(1,3) = 35; K(2,3) = 32 K(1,2,3) = 35
Stand-alone method:C(1) = 35/6 = 5.83; C(2) = 35/3 = 11.66; C(3) = 35/2 = 17.5
24
Incremental Method and Shapley ValueApplication to the exampleCost Function
Cost increments occuring when divisions join the pool in a certain order for each possible sequence

K(1) = 10; K(2) = 20; K(3) = 30K(1,2) = 25; K(1,3) = 35; K(2,3) = 32
K(1,2,3) = 35
26
Revenues and Bundled Products
A bundled product is a package of two or moreproducts (or services) sold for a single price. Bundled product sales are also referred to as “suite sales.” The individual components of the bundle also may be sold as separate items at their own“stand-alone” prices.Examples

These programs are offered stand-alone or in a bundleStand-alone Unit

Revenue Allocation Methods
The two main revenue allocation methods1. The stand-alone method with alternative weights
a) Selling pricesb) Unit costsc) Physical unitsd) Stand-alone product revenues
2. The incremental method with alternative sequences3. The Shapley Value
29
Stand-Alone Revenue Allocation Method
Consider the Grammar and Translation suite, which sells for $290 per copy.1a) Grammar: $290× 255/(255 + 85) = $217.50
Translation: $290× 85/(255 + 85) = $72.501b) Grammar: $290× 180/(180 + 45) = $232
Translation: $290× 45/(180 + 45) = $581c) Grammar: $290/2 = $145
Translation: $290/2 = $1451d) Assume that the stand-alone revenues in 2003
Grammar $734,400; Translation $81,600, Composition $133,200.
Grammar: $734,400 ÷ $816,000 = 0.90, $290 × 0.90 = $261Translation: $81,600 ÷ $816,000 = 0.10, $290 × 0.10 = $29
30
Incremental Revenue Allocation Method
The first-ranked product is termed the primary product in the bundle
If the suite selling price exceeds the stand-alone price of the primary product, the primary product is allocated 100% of its stand-alone revenue.
The second-ranked product is termed the first incremental product The third-ranked product is the second incremental product, and so on. Assume that Grammar is designated as the primary product:
Grammar and Translation suite selling price = $290 per copyAllocated to Grammar: $255Remaining to be allocated: ($290 – $255) = $35 > Translation
