Accounting for Costs & ledger
Accounting
• Cost records are a detailed breakdown of the
information contained in the purchases account,
the wages and salaries account and all the
expense accounts in the nominal ledger.

Example of Direct & Indirect
Materials
• During one month, a company incurred materials
cost of MVR 28,000. There were no opening or
closing inventories at the beginning & end of the
month. Direct material cost were MVR 20,000 (all
paid for in cash), & indirect materials cost were
MVR 1,000 for production, MVR 5,000 for
administration & MVR 2,000 for sales &
distribution. All materials are kept in stores &
requisitioned when required.

Control Accounts
• A control account is an account which records total
cost, unlike an individual ledger account which
records individual Dr & Cr.

Cost Bookkeeping Systems
• There are two main cost bookkeeping systems,
interlocking systems and integrated systems.
![Page 16: Chapter 8 Cost Bookkeeping - Ibrahim Sameer · PDF fileChapter 8 Cost Bookkeeping ... • In an integrated accounting system the following is the double entry for over absorption:](https://reader031.fdocuments.in/reader031/viewer/2022020302/5a85bfed7f8b9a14748c4d99/html5/thumbnails/16.jpg)
Integrated Systems
• Modern cost accounting system (computerized)
integrate cost accounting information & financial
accounting information and are known as
integrated systems.
![Page 17: Chapter 8 Cost Bookkeeping - Ibrahim Sameer · PDF fileChapter 8 Cost Bookkeeping ... • In an integrated accounting system the following is the double entry for over absorption:](https://reader031.fdocuments.in/reader031/viewer/2022020302/5a85bfed7f8b9a14748c4d99/html5/thumbnails/17.jpg)
Interlocking Systems
• An interlocking system is a cost bookkeeping
system where separate ledger accounts are kept
for both the cost accounting function & financial
accounting function. Such system necessitates the
reconciliation of the profit produced by the
separate income statement.
![Page 18: Chapter 8 Cost Bookkeeping - Ibrahim Sameer · PDF fileChapter 8 Cost Bookkeeping ... • In an integrated accounting system the following is the double entry for over absorption:](https://reader031.fdocuments.in/reader031/viewer/2022020302/5a85bfed7f8b9a14748c4d99/html5/thumbnails/18.jpg)
Interlocking Systems
• The cost accounts use the same basic data
(purchases, wages & so on) as the financial
accounts, but frequently adopt different bases for
matters such as depreciation & inventory valuation.
![Page 19: Chapter 8 Cost Bookkeeping - Ibrahim Sameer · PDF fileChapter 8 Cost Bookkeeping ... • In an integrated accounting system the following is the double entry for over absorption:](https://reader031.fdocuments.in/reader031/viewer/2022020302/5a85bfed7f8b9a14748c4d99/html5/thumbnails/19.jpg)
Principal A/C in a System of
Interlocking A/C
• (a) the resources a/c
• Material control a/c or stores ledger control a/c
• Wages (& salaries) control a/c
• Production OH control a/c
• Administration OH control a/c
• Selling & distribution OH control a/c
![Page 20: Chapter 8 Cost Bookkeeping - Ibrahim Sameer · PDF fileChapter 8 Cost Bookkeeping ... • In an integrated accounting system the following is the double entry for over absorption:](https://reader031.fdocuments.in/reader031/viewer/2022020302/5a85bfed7f8b9a14748c4d99/html5/thumbnails/20.jpg)
Principal A/C in a System of
Interlocking A/C
• (b) accounts which record the cost of production
items from start of production work through to cost
of sales:
• WIP control a/c
• Finished goods control a/c
• Cost of sales control a/c
![Page 21: Chapter 8 Cost Bookkeeping - Ibrahim Sameer · PDF fileChapter 8 Cost Bookkeeping ... • In an integrated accounting system the following is the double entry for over absorption:](https://reader031.fdocuments.in/reader031/viewer/2022020302/5a85bfed7f8b9a14748c4d99/html5/thumbnails/21.jpg)
Principal A/C in a System of
Interlocking A/C
• (c) Sales a/c
• (d) The costing income statement
• (e) The under/over absorbed OH a/c
• (f) Cost ledger control a/c (in the cost ledger)
• (g) Financial ledger control a/c (in the financial
ledger)

Advantages of Interlocking
System
• They feature two ledgers, each of which fulfill
different purpose
![Page 23: Chapter 8 Cost Bookkeeping - Ibrahim Sameer · PDF fileChapter 8 Cost Bookkeeping ... • In an integrated accounting system the following is the double entry for over absorption:](https://reader031.fdocuments.in/reader031/viewer/2022020302/5a85bfed7f8b9a14748c4d99/html5/thumbnails/23.jpg)
Disadvantages of Interlocking
System
• Profits of separate cost & financial a/c must be
reconciled.
• They require more administration time.
• They are more costly to run.
![Page 24: Chapter 8 Cost Bookkeeping - Ibrahim Sameer · PDF fileChapter 8 Cost Bookkeeping ... • In an integrated accounting system the following is the double entry for over absorption:](https://reader031.fdocuments.in/reader031/viewer/2022020302/5a85bfed7f8b9a14748c4d99/html5/thumbnails/24.jpg)
Advantages of Integrated System
• It save administration time & cost, because only
one set of a/c need to be maintained instead of
two.
• There is also no need to reconcile the profits of the
separate cost and financial a/c.
![Page 25: Chapter 8 Cost Bookkeeping - Ibrahim Sameer · PDF fileChapter 8 Cost Bookkeeping ... • In an integrated accounting system the following is the double entry for over absorption:](https://reader031.fdocuments.in/reader031/viewer/2022020302/5a85bfed7f8b9a14748c4d99/html5/thumbnails/25.jpg)
Disadvantages of Integrated
System
• The main limitation of integrated a/c is that one set
of a/c is expected to fulfill two different purposes,
the cost a/c provide internal management
information & the financial a/c are used for external
reporting. At times external reporting & internal
management information may conflict.

Production Overhead Control
Account
• In production OH control A/c it will record all of the
total actual expenditure incurred on indirect costs
and the amount absorbed into individual units, job
or process.

Under / Over Absorption
• In an integrated accounting system the following is
the double entry for over absorption:
• Dr: OH control A/c
• Cr: Income statement
• In an integrated accounting system the following is
the double entry for under absorption:
• Dr: Income statement
• Cr: OH control A/c

Notional cost
• In some interlocking costing system, there maybe
notional costs. These are costs that are introduced
into costing system in order to present a more
realistic measure of the cost of an item. The most
common types of notional cost are notional rent
and notional interest.

Notional cost
• Notional costs must be recorded in the cost
accounts. The actual notional cost is recorded as
Dr entry in the appropriate OH a/c, and the
corresponding Cr entry is to the cost accounting
income statement.
