2 7-2 Copyright © 2004 by Nelson, a division of Thomson Canada Limited. Learning Objectives l Describe the difference between support departments and producing departments. l Calculate single and multiple charging rates for a support department.

3 7-3 Copyright © 2004 by Nelson, a division of Thomson Canada Limited. Learning Objectives l Allocate support-department costs to producing departments using the direct, sequential, and reciprocal methods. l Calculate departmental overhead rates.

4 7-4 Copyright © 2004 by Nelson, a division of Thomson Canada Limited. Support and Producing Departments Support departments are units within an organization that provide essential support services for producing departments. Examples:maintenance, grounds, engineering, housekeeping, personnel, and stores Producing departments are units within an organization that are directly responsible for creating the products or services sold to customers. Examples:Services: auditing, tax, management advisory Manufacturing: grinding and assembly

5 7-5 Copyright © 2004 by Nelson, a division of Thomson Canada Limited. Definitions l Mutually beneficial costs, which occur when the same resource is used in the output of two or more services or products, are common costs. Example:security guard wages at a factory l Causal factors are variables or activities within a producing department that bring about support service costs.

6 7-6 Copyright © 2004 by Nelson, a division of Thomson Canada Limited. Steps in Allocating Support Department Costs to Producing Departments 1.Departmentalize the company. 2.Classify each department as a support or producing department. 3.Trace all overhead costs in the company to a support or producing department.

7 7-7 Copyright © 2004 by Nelson, a division of Thomson Canada Limited. Steps in Allocating Support Department Costs to Producing Departments 4.Allocate support-department costs to the producing departments. 5.Calculate predetermined overhead rates for producing departments. 6.Allocate overhead costs to the units of individual products through the predetermined overhead rates.

8 7-8 Copyright © 2004 by Nelson, a division of Thomson Canada Limited. Objectives Objectives of Allocation l To obtain a mutually agreeable price. l To compute product-line profitability. l To predict the economic effects of planning and control. l To value inventory. l To motivate managers.

10 7-10 Copyright © 2004 by Nelson, a division of Thomson Canada Limited. Support Departments and Producing Departments Support departments provide support for production departments Producing departments are responsible for the creation of goods or services Goods and Services

11 7-11 Copyright © 2004 by Nelson, a division of Thomson Canada Limited. A Single Charging Rate Example l A firm developed an in-house photocopying department to serve its three producing departments (audit, tax, and management advisory systems or MAS). l The costs of the photocopying department include fixed costs of $26,190 per year and variable costs of $0.023 per page copied. l Estimated usage in pages by the three producing departments is as follows: Audit department94,500 Tax department67,500 MAS department108,000 Total270,000 ======

12 7-12 Copyright © 2004 by Nelson, a division of Thomson Canada Limited. A Single Charging Rate (continued) Total costs = $26,190 + (270,000 x $0.023) = $32,400 Overhead rate = $32,400  270,000 = $0.12 per page Suppose the actual usage per department is: Audit department92,000 Tax department65,000 MAS115,000

13 7-13 Copyright © 2004 by Nelson, a division of Thomson Canada Limited. A Single Charging Rate (continued) The total photocopying department charges would be as shown: Total # of PagesOH rateCharges Audit92,000$0.12$11,040 Tax65,000$0.127,800 MAS115,000$0.1213,800 Total272,000$32,640======

16 7-16 Copyright © 2004 by Nelson, a division of Thomson Canada Limited. Budgeted Versus Actual Usage When we allocate support-department costs to the producing departments, should we allocate actual or budgeted costs? Budgeted costs

17 7-17 Copyright © 2004 by Nelson, a division of Thomson Canada Limited. Budgeted Versus Actual Usage (continued) There are two basic reasons for allocating support-department costs. 1.To assign costs to units produced 2.For performance evaluations

18 7-18 Copyright © 2004 by Nelson, a division of Thomson Canada Limited. Choosing A Service Department Cost Allocation Method The three methods for allocating service department costs to producing departments are: The Direct Method The Sequential Method The Reciprocal Method

22 7-22 Copyright © 2004 by Nelson, a division of Thomson Canada Limited. Reciprocal Method The reciprocal method of allocation recognizes all interactions among support departments.

Reciprocal Method (continued) Support Departments Producing Departments PowerMaint.GrindingAssembly Direct Costs: Fixed$200,000$100,000$ 80,000$50,000 Variable 50,000 60,000 20,000 10,000 Total$250,000$160,000$100,000$60,000 =========================== Proportion of Output Used by PowerMaint.GrindingAssembly Allocation Ratios: Power Maintenance

24 7-24 Copyright © 2004 by Nelson, a division of Thomson Canada Limited. Reciprocal Method (continued) The cost equation for each support department can be expressed as follows: P= Direct costs + Share of Maintenance’s cost P=$250, (M) M= Direct costs + Share of Power’s costs M= $160, P

25 7-25 Copyright © 2004 by Nelson, a division of Thomson Canada Limited. Reciprocal Method (continued) Substituting the Power equation into the Maintenance equation, we get: M =$160, ($250, M) M =$160,000 + $50, M 0.98M =$210,000 M =$214,286

26 7-26 Copyright © 2004 by Nelson, a division of Thomson Canada Limited. Reciprocal Method (continued) Substituting the value for M into the Power equation we get: P =$250, ($214,286) P =$250,000 + $21,429 P =$271,429

28 7-28 Copyright © 2004 by Nelson, a division of Thomson Canada Limited. Departmental Overhead Rates The overhead rate for the grinding department is computed as follows (assuming the normal level of activity is 71,000 MH): OH rate = $355,000  71,000 = $5.00 per MH The overhead rate for the assembly department is computed as follows (assuming the normal level of activity is 107,500 DLH): OH rate = $215,000  107,500 = $2.00 per DLH
