This file will provide you the basic details of internal control under auditing in a summarized and concise form.

1. INTERNAL CONTROL
 Internal control is a process effected by plan
management, BOD and other personnel, and those
charged with governance, and designed to provide
reasonable assurance regarding the achievement of
objectives in the following categories :-
 reliability of financial reporting.
 Compliance with laws & regulations.
 Effectiveness & efficiency of operations.
 Internal Control is also necessary for survival of an
organization's success.

2.  A system of controls, financial and otherwise
established by management in order to carry on the
business of the company in an orderly and efficient
manner to ensure the adherence to management
policies, safeguard the assets, and secure as much as
possible the completeness of an internal control system
– De Paula
 Internal controls as a system comprising of controls
environment and procedures. It includes polices and
ways adapted by management of an enterprise to assist
it in achieving its objectives – The International
standards of Auditors.

3. INTERNAL CONTROL OBJECTIVES
 Authorization
 Completeness
 Accuracy
 Validity
 Physical Safeguards and Security
 Error Handling
 Segregation of Duties

4. INTERNAL CONTROL ELEMENTS
monitoring
Control
activities
Risk management
Control environment
Management’s objectives
Information &
communication

5. ADVANTAGES OF INTERNAL CONTROL
 Increase in operational efficiency
 Accurate Recording
 Safeguarding Assets
 Compliance
 Protection of Employees

6. INTERNAL CHECK
 Checks on the day-to-day transactions which operate
continuously as a part of the routine systems.
 The main objective of internal check is prevention of
errors and frauds and/or detection of errors and frauds
at the earliest.
 It also ensures efficiency of the accounting system
followed by the organization and enables easy
preparation of financial statements.
 Internal check discourages fraud and collusion among
employees by instilling a fear of detection in their minds.

9. TECHNIQUES OF INTERNAL CONTROL
SYSTEM
 Preventive Controls techniques- designed to discourage
errors or irregularities from occurring. They are proactive in
nature that helps to ensure departmental objectives are being
met. Ex-
 Segregation of Duties
 Approvals, Authorizations, and Verifications
 Security of Assets
 Detective Controls techniques- designed to find errors or
irregularities after they have occurred. Ex-
 Reviews of Performance
 Reconciliations
 Physical Inventories
 Internal Audits

10. AUDIT TESTING
 An audit test is a procedure performed by either an
external or internal auditor in order to assess the
accuracy of various financial statement assertions. The
two common categorizations of audit tests are
substantive tests and tests of internal controls
 A substantive audit test is a direct test that validates a
financial statement balance, while internal control tests
are focused on key controls, such as management
reviews or standardized templates that are designed
to prevent and detect material misstatements
 Audit tests typically are performed on a sample basis
over an existing group of similar transactions. Sampling
approaches can either be statistical or non-statistical.

11. SAMPLING IN AUDIT TESTING
 a process of selecting a subset of a population of items for
the purpose of making inferences to the whole
population.
Need for Audit Sampling
1. Developing a consistent approach to audit areas;
2. Providing a framework within which sufficient audit
evidence is obtained;
3. Forcing clarification of audit thinking in determining
how the audit objectives will be met;
4. Minimizing the risk of over-auditing; and
5. Facilitating more expeditious review of working papers

12. STATISTICAL SAMPLING IN AUDIT
 Statistical sampling involves the random selection of a
number of items for inspection and is endorsed by the
accountancy bodies.
 In statistical sampling, each item has a calculable chance of
being selected.
 Statistical sampling allows an auditor’s judgment to be
concentrated on those areas of the audit where it is most
needed.
 It allows the quantification of key factors and the risk of
errors.
 This is not to suggest that statistical sampling methods
remove the need for professional judgment, but rather that
they allow elements of the evaluation process to be quantified,
measured and controlled.

13. INTER-FIRM COMPARISON
 It is technique of evaluating the performance, efficiency,
costs and profits of firms in an industry.
 It consists of voluntary exchange of information/data
concerning costs, prices, profits, productivity and overall
efficiency among firms engaged in similar type of operations
for the purpose of bringing improvement in efficiency and
indicating the weaknesses. Such a comparison will be possible
where uniform costing is in operation.
 An inter-firm comparison indicates the efficiency of
production and selling, adequacy of profits, weak spots in the
organization, etc. and thus demands from the firm’s
management an immediate suitable action.
 Such a comparison may be carried out in electrical industry,
printing firms, cotton spinning firms, pharmaceuticals, cycle
manufacturing, etc.

14. INTRA-FIRM COMPARISON
 comparison among different units/products/strategic
business unit (SBU) of a firm.
 This comparison is possible only when uniform
costing methods and practices are being adopted by all
units and SBUs.
 Intra firm comparison helps the management in
identifying the units/Strategic SBUs which have not been
performing as per the internal benchmark or standards
achieved by other units SBUs.
 This comparison is difficult sometime when the firm is
dealing in different product/sectors and their working
conditions are significantly different.

15. AUDIT IN DEPTH
 checking a transaction extensively from origin to
end.
 It is an audit technique which is used to evaluate the
effectiveness of internal control system in an
organization.
 It is used in investigation exercises whereby the
objective is to thorough examination of transactions
or records.
 Also known as vertical vouching as against
horizontal vouching.
