The Expected Deviations Rate is a critical concept in auditing that denotes the extent of non-compliance with recognized control procedures that an auditor anticipates finding when performing compliance tests on a population or a sample of it. This concept plays an essential role in assessing the efficacy of internal controls within an organization.
Historical Context
The notion of auditing and internal controls has evolved significantly over the centuries, influenced by economic developments, regulatory changes, and corporate scandals. The concept of the Expected Deviations Rate emerged as auditors sought quantitative methods to measure and predict the reliability of internal controls.
Types/Categories
1. Expected Deviations Rate in Financial Audits
- Used primarily to evaluate the internal controls over financial reporting.
2. Expected Deviations Rate in Compliance Audits
- Focuses on compliance with laws and regulations.
3. Expected Deviations Rate in Operational Audits
- Pertains to the effectiveness and efficiency of operational controls.
Key Events
- Sarbanes-Oxley Act (2002): Introduced stringent requirements for internal controls and auditing standards.
- COSO Framework (1992, revised in 2013): Provided a structured approach to evaluating internal control systems, influencing the use of Expected Deviations Rate.
Detailed Explanations
Importance
Understanding the Expected Deviations Rate helps auditors determine the extent of testing needed and assess the risk associated with non-compliance. It forms the basis for planning audit procedures and ensuring sufficient evidence is obtained to form a valid conclusion.
Applicability
- Internal Auditors: Used to evaluate internal controls within an organization.
- External Auditors: Helps assess the accuracy and fairness of financial statements.
- Regulatory Bodies: Ensures organizations comply with laws and regulations.
Considerations
When determining the Expected Deviations Rate, auditors consider factors such as past audit findings, changes in processes, and the inherent risk of the control environment.
Mathematical Formulas/Models
The Expected Deviations Rate can be calculated using statistical sampling techniques, such as:
EDR = (Number of Deviations Observed) / (Total Sample Size)

Examples
- Example 1: An auditor tests 100 transactions and finds 5 deviations, resulting in an Expected Deviations Rate of 5%.
- Example 2: In an organization with historically strong controls, an auditor might expect a lower deviations rate, leading to fewer required sample tests.
Related Terms
- Compliance Test: Procedures an auditor uses to determine whether internal controls are functioning as intended.
- Control Environment: The set of standards, processes, and structures that provide the foundation for carrying out internal controls.
- Risk Assessment: The identification and analysis of relevant risks to achieving objectives, forming a basis for determining how risks should be managed.
Comparisons
- Expected Deviations Rate vs. Tolerable Deviations Rate: The Expected Deviations Rate is what the auditor expects to find, whereas the Tolerable Deviations Rate is the maximum rate of deviations that can be accepted without modifying the planned level of assurance.
Interesting Facts
- The Expected Deviations Rate is crucial in both manual and automated audit processes.
- Auditors often use historical data and industry benchmarks to estimate the Expected Deviations Rate.
Inspirational Stories
The Enron Scandal
The collapse of Enron highlighted the importance of robust internal controls and effective auditing. Post-scandal reforms emphasized the need for auditors to rigorously assess and predict deviations in control procedures.

FAQs
Q1: Why is the Expected Deviations Rate important in audits? A1: It helps in planning the nature, timing, and extent of audit procedures and in evaluating the efficiency of internal controls.
Q2: How is the Expected Deviations Rate determined? A2: It is estimated based on historical data, industry benchmarks, and the auditor’s judgment of the control environment.
Q3: What is the difference between Expected Deviations Rate and Actual Deviations Rate? A3: The Expected Deviations Rate is what the auditor anticipates finding, whereas the Actual Deviations Rate is what is found upon testing.

Summary
The Expected Deviations Rate is a foundational concept in auditing that helps auditors anticipate the level of non-compliance within a population. By accurately estimating this rate, auditors can design effective compliance tests, assess internal control efficacy, and ensure the reliability of financial reporting. Understanding this rate involves a mix of historical data analysis, statistical sampling, and professional judgment, making it a crucial tool in the auditor’s toolkit.
