When all the items are collected properly under suitable account headings, the next step is
allocation and apportionment of such expenses to cost centres. This is also known as
departmentalisation of overhead. Departmentalisation of production overheads is the
process of identifying production overhead expenses with different production/service
departments or cost centres. It is done by means of allocation and apportionment of
overheads among various departments.
TYPES OF DEPARTMENTS:

7. PRIMARY DISTRIBUTION OF OVERHEAD:
Primary Distribution is the allocation or appointment of different items of overhead to both production and
service departments on suitable basis. There is no partiality between production and service department in
making primary distribution.
SECONDARY DISTRIBUTION
secondary distribution is the reapportionment of service department expenses among the production
departments after completion of primary distribution. While making secondary distribution, some common
bases of apportionment are taken.
8. ABSORPTION OVERHEAD:
The process of charging the total overheads of production departments to the output of
that department is called overhead absorption.
