1. Evaluation of Internal Control System

2. Contrast management’s need for internal control with the auditor’s
Learning Objective 1
Contrast management’s need for
internal control with the auditor’s
need to consider internal control
when designing an audit.

3. Internal Controls - Definition
"Internal control system" means all the policies and procedures (internal controls) adopted by the management of an entity to assist in achieving management's objective of ensuring, as far as practicable,
the orderly and efficient conduct of its business, including adherence to management policies,
the safeguarding of assets,
the prevention and detection of fraud and error,
the accuracy and completeness of the accounting records,
and the timely preparation of reliable financial information.

4. Key Concepts Management’s Responsibility Reasonable Assurance Inherent
Limitations

5. Client’s Concerns Reliability of financial reporting
Efficiency and effectiveness of operations
Compliance with applicable laws
and regulations

6. Auditor Concerns Controls related to reliability of
financial reporting
Controls over classes of transactions
(more than on account balances)

7. Explain the components
Learning Objective 2
Explain the components
of internal control.

8. Internal Controls – 2 Components
“The Control Environment“:
Which means the overall attitude, awareness and actions of directors and management regarding the internal control system and its importance in the entity. Factors affecting include:
The function of the board of directors and its committees.
Management's philosophy and operating style.
The entity's organizational structure and methods of assigning authority and responsibility.
Management's control system including the internal audit function, personnel policies and procedures and segregation of duties.

9. Internal Controls – 2 Components
"control procedures" which means those policies and procedures in addition to the control environment which management has established to achieve the entity's specific objectives.
“SPAM SOAP”

10. Adequate Separation of Duties
A transaction can be dissected as follows;
C = Custody
A = Authority
R = Recording
E = Execution

11. Proper Authorization of Transactions and Activities
General authorization
General policies to be followed. Approves all transactions within the limits set by the policy.
Specific authorization
Relates to the authorization of individual transaction

12. Adequate Documents and Records
Prenumbered consecutively
Prepared at the time of transaction
Simple enough to ensure understanding
Designed for multiple uses
Constructed to encourage correct preparation

13. Physical Control over Assets and Records
Physical precautions
Controls related to IT equipment,
programs, and data files
Physical
controls
Access
controls
Backup and
recovery
procedures

14. Independent Checks on Performance
The need for independent checks
arise because internal control tends
to change over time unless there is
a mechanism for frequent review.

15. The Accounting System
"Accounting system" means the series of tasks and records of an entity by which transactions are processed as a means of maintaining financial records. Such systems identify, assemble, analyze, calculate, classify, record, summarize and report transactions and other events.

16. The Accounting System - Objectives
Transactions are executed in accordance with management's general or specific authorization.
All transactions and other events are promptly recorded in the correct amount, in the appropriate accounts and in the proper accounting period so as to permit preparation of financial statements in accordance with the Sri Lanka Accounting Standards.
Access to assets and records is permitted only in accordance with management's authorization.
Recorded assets are compared with the existing assets at reasonable intervals and appropriate action is taken regarding any differences.

17. Explain methods used to obtain an understanding
Learning Objective 3
Explain methods used to
obtain an understanding
of internal control.

18. Understanding Internal Control and Assessing Control Risk
Obtain Understanding of Internal Control:
Design and Operation
Assess Control Risk
Test Controls
Decide Planned Detection Risk
and Substantive Tests

19. Reasons for Sufficiently Understanding Internal Control
SLAuS requires the auditor to
obtain an understanding of internal
control for every audit.
Minimum audit
planning matters
Auditability
Potential material
misstatements
Detection risk
Design of test

20. Procedures to Determine Design and Placement
Update and evaluate auditor’s previous
experience with the entity.
Make inquires of client personnel.
Read client’s policy and systems manuals.
Examine documents and records.
Observe entity activities and operations.

21. Documentation of the Understanding

22. Assess control risk by linking strengths and weaknesses of
Learning Objective 4
Assess control risk by linking
strengths and weaknesses of
internal control to transaction-
related audit objectives.

23. Assess Control Risk Obtain sufficient understanding for planning.
Assess whether the entity is auditable.
Determine assessed control risk.
Assess if a lower control risk could be supported.
Determine the appropriate assessed control risk.

24. Assess Control Risk Identify transaction-related audit objectives.
Identify specific controls.
Identify and evaluate weaknesses.

25. Identify and Evaluate Weaknesses
Identify existing controls.
Identify the absence of key controls.
Determine misstatements that could result.
Consider compensating controls.

26. Communication
As a result of obtaining an understanding of the accounting and internal control systems and tests of control, the auditor may become aware of weaknesses in the systems. The auditor should make management aware, as soon as practical and at an appropriate level of responsibility, of material weaknesses in the design or operation of the accounting and internal control systems, which have come to the auditor's attention. The communication to management of material weaknesses would ordinarily be in writing.

27. Describe the process of designing and performing tests of controls.
Learning Objective 5
Describe the process of designing
and performing tests of controls.

28. The Need for Test of Controls
If the auditor, after obtaining an understanding of the accounting system and control environment, expects to be able to rely on his assessment of control risk to reduce the extent of substantive procedures, he should make a preliminary assessment of control risk for material financial statement assertions, and plan and perform tests of control to support that assessment.

29. Tests of Controls The procedures to test effectiveness
of controls in support of a reduced
assessed control risk are called
tests of controls.

30. Procedures for Tests of Controls
Make inquiries of client personnel.
Examine documents, records, and reports.
Observe control-related activities.
Reperform client procedures.

31. Extent of Procedures Reliance on evidence from prior year’s audit
Testing less than the entire audit period

32. Decide Planned Detection Risk and Design Substantive Tests
The auditor uses the results of the control risk
assessment process and tests of controls to
determine the planned detection risk and
related substantive tests.

33. Decide Planned Detection Risk and Design Substantive Tests
The level of detection risk relates directly to the auditor's substantive procedures. The auditor's control risk assessment, together with the inherent risk assessment, influences the nature, timing and extent of substantive procedures to be performed to reduce detection risk, and therefore audit risk, to an acceptably low level. Some detection risk would always be present even if an auditor were to examine 100 percent of the account balance or class of transactions because, for example, most audit evidence is persuasive rather than conclusive.

34. Decide Planned Detection Risk and Design Substantive Tests
The auditor should consider the assessed levels of inherent and control risks in determining the nature, timing and extent of substantive procedures required to reduce audit risk to an acceptable level..
