The Importance Of Internal Control

Question 1

Internal control importance

Answer 1

Let’s explore the auditor’s assessment of internal controls and how it influences the selection of audit procedures, focusing on both controls and substantive tests.

Explanation: According to ISA 315 (revised 2019), the auditor must assess risk at both the financial statement level and the assertion level. ISA 330 requires the auditor to respond to these risks by selecting appropriate audit procedures based on the assessment of inherent risk and control risk.

Inherent Risk: The susceptibility of an assertion to a misstatement that could be material, assuming there are no related controls.

Control Risk: The risk that a misstatement that could occur in an assertion and that could be material will not be prevented, or detected and corrected, on a timely basis by the entity’s internal control.

Explanation: Internal control is a process designed, implemented, and maintained by management to provide reasonable assurance regarding the achievement of objectives related to:
- Reliability of financial reporting
- Efficiency and effectiveness of operations
- Compliance with applicable laws and regulations

Key Points:
- Management is responsible for designing and implementing internal controls.
- Internal controls address financial, operational, and compliance risks.
- The auditor assesses and evaluates these controls to plan the audit.

Let’s consider a company with the following scenario:

Scenario: A company has implemented internal controls over its sales process to ensure accurate financial reporting and compliance with regulations.

1. Assessment of Internal Controls:
   
   • Inherent Risk: The auditor assesses the inherent risk of misstatement in sales transactions due to complex pricing structures.
   • Control Risk: The auditor evaluates the effectiveness of controls over sales authorization and recording.
2. Selection of Audit Procedures:
   
   • Controls Testing: The auditor tests the controls over sales authorization to ensure they are operating effectively. This might include checking a sample of sales transactions to verify that they were properly authorized.
   • Substantive Testing: Based on the assessment of control risk, the auditor decides to perform substantive tests on sales transactions. This could involve detailed testing of a sample of sales invoices to verify accuracy and completeness.

Controls Testing: The auditor selects a sample of 50 sales transactions to test for proper authorization. If the controls are found to be effective, the auditor may reduce the extent of substantive testing.

Substantive Testing: The auditor performs detailed testing on a sample of 100 sales invoices to verify that the amounts recorded in the financial statements are accurate and complete.

The auditor’s assessment of internal controls significantly influences the selection of audit procedures. By understanding and evaluating the internal controls, the auditor can determine the appropriate mix of controls testing and substantive testing to respond to the assessed risks.

Modern auditing often employs a systems-based approach, where the auditor relies on the accounting systems and related controls to ensure transactions are properly recorded. Here’s a detailed look at this approach:

• Assumption: If the systems and internal controls are adequate, transactions should be processed correctly.
• Focus: The emphasis is on the systems processing the transactions rather than on the transactions themselves.

1. Establish Systems and Controls: The auditor must first understand the systems and controls in place.
2. Evaluate Effectiveness: The auditor evaluates the effectiveness of these controls to determine if they can be relied upon.

1. Design of Internal Controls: Are the controls designed to prevent or detect and correct material misstatements?
2. Implementation of Controls: Are the controls properly operated by management and employees?

The evaluation of internal controls helps the auditor assess control risk, a key element in the audit risk model. Control risk is the risk that a misstatement that could occur in an assertion and that could be material will not be prevented, or detected and corrected, on a timely basis by the entity’s internal control.

• Tests of Controls: These tests evaluate the effectiveness of the internal controls.
• Substantive Tests: These tests focus on the transactions and balances in the financial statements.

• Extensive Substantive Testing: If controls are ineffective, the auditor performs extensive substantive procedures. This approach is called a transactions-based approach.

• Tests of Controls: If controls are strong, the auditor performs tests on the controls to verify their effectiveness.
• Reduced Substantive Testing: With effective controls, the auditor can reduce the extent of substantive testing. This approach is called a systems-based approach.

1. Planning and Risk Assessment: Initial phase where the auditor assesses risks.
2. Assessment of Internal Controls:
   
   • Weak Controls: Leads to extensive substantive testing.
   • Strong Controls: Leads to tests of controls and reduced substantive testing.
3. Overall Review of Financial Statements: Final phase before issuing the audit report.

Scenario: An auditor is auditing a company’s payroll system.

1. Understanding Systems and Controls: The auditor reviews the payroll system and related controls, such as authorization of payroll changes and segregation of duties.
2. Evaluating Effectiveness:
   
   • Design: The auditor checks if the controls are designed to prevent unauthorized payroll changes.
   • Implementation: The auditor tests if the controls are properly implemented by reviewing a sample of payroll transactions.
3. Assessing Control Risk: Based on the evaluation, the auditor assesses the control risk.
4. Audit Approach:
   
   • Weak Controls: If controls are weak, the auditor performs extensive substantive testing on payroll transactions.
   • Strong Controls: If controls are strong, the auditor performs tests of controls and reduces substantive testing.

By following these steps, the auditor can effectively use internal controls to plan and execute the audit.
