Overhead Accounting Allocation & Apportionment of Overheads - PowerPoint Presentation

1. Overhead Accounting

2. Allocation & Apportionment of Overheads After the overheads costs are collected & codified the next step is Allocation ands Apportionment.Departmentalization or Primary DistributionIt is the process of allocation & apportionment of overhead cost to different departments or cost centres. Cost centres/ departments are divided into:Production deptt. Service Deptt

3. Production DepartmentA production deptt/ cost centre: is engaged in production activity by conversion of raw material into finished production. The number of such departments and their number will depend upon the nature of industry, type of work performed and the size of the factory. For example, in Steel Rolling Mill, Hot Mill, Cold Mill, Pickling Shop, Annealing Shop, Hardening, Polishing and Grinding are the producing departments.

4. Service DepartmentA Service Deptt/ costcentre : are those which are ancillary to and render service to other production and service cost centres. The number of departments in a factory and the names to be assigned to them depends upon size of the factory, nature of industry and the nature of service rendered. The service departments, common to most concerns are stores, cost office, personnel department, planning and progress department, tool room, hospital and dispensary, machine maintenance and electrical maintenance section

5. Allocation of overheadsAllocation is the process of assigning the whole item of cost directly to a cost centreAllocation can be done only when the exact item of overhead cost in a cost centre is definitely known.For example, the whole of overtime wages paid to the workers relating to a particular department should be charged to that department or the cost of repairs and maintenance of a particular machine should be charged to that particular department wherein the machine is located

6. Apportionment of OverheadsApportionment refers to proportionate distribution of overheads to more than one cost centre on a suitable basis. Thus where a overhead cost is common to different cost centres, it is charged to them on a suitable basis. For eg. factory rent, insurance, factory lighting etc. may benefit a number of departments. The need to be apportioned (i.e. distribution to various departments in the factory)

7. Distinction between allocation & apportionment

8. Basis of Apportionment

9. Primary Distribution of OverheadsPrimary distribution of overheads refers to allocation and apportionment of overhead expenses among production and service departments of an organization.This process involves allocation of overheads which can be directly identified with a particular department and apportionment of common item of overheads on appropriate basis among all the departments.The entire process of allocation and apportionment is systematically presented in a perform which is known as primary distribution overhead summary or overhead distribution summary.

10. Primary distribution Overhead summary While preparing overheads distribution summary, it is important to note: that the direct costs of the service departments should be considered as overheads. Hence the direct material, direct labour and direct expenses of the service departments are allocated directly and recorded in the overheads distribution summary since these are overheads from production point of view.But the direct material, direct labour and direct expenses of the production departments need to be excluded from this summary since these are not overheads.

11. Re-apportionment of Service Department cost (secondary distribution)Once the overheads have been allocated or apportioned to production & service department the next step is to reapportion the total cost of service department to production department. The ultimate objective is to charge the entire overheads to cost units as cost units are produced in the production deptt. Thus the cost of the service deptt must be charged to the production deptt. This is known as Secondary distribution

14. Reapportionment to production department onlyThis method is adopted when the various service departments render services only to the production department and there is no exchange of services among them. Do eg. 3 from S. singh pg 5.15ORDo illustration 4.3 from MN Arora pg 4.14

15. Reapportionment to production as well as service deptt. This method is followed when the service department provides services not only to the production deptt but also to other service deptt.For eg. Power house service deptt provides electricity service to both production and other services department like maintenance deptt, canteen deptt., warehousing deptt etc. This type of inter-service deptt apportionment may be either reciprocal or non-reciprocal.

16. Reciprocal and non-reciprocal basis of apportionment Non- Reciprocal basis: is when the service deptt renders service to the production and other service deptt but does not receive services of other deptts i.e one-way flow.Service department are not inter-dependentWe follow the step- ladder method: Do eg. 4 from S. singh. Pg 5.17 or ills 4.4 mn arora pg 4.16

17. Reciprocal and reciprocal basis of apportionment This method of apportionment is used when the service department renders service to production as well as other service departments and in turn also receives services from other service department. Service departments are inter-dependent on one another.For eg: Power house provides electricity to maintenance deptt and in turn receives maintenance from them.
