Lecture 6 Flashcards
What is Audit Sampling?
Audit sampling involves testing less than 100% of a population to provide a reasonable basis for conclusions. Defined by ISA 530 as: “The application of audit procedures to less than 100% of items within a population of audit relevance such that all sampling units have a chance of selection.”
Auditors form an opinion about the truth and fairness of financial statements based on samples rather than testing every transaction.
What is Sampling Risk?
The risk that the sample selected is not representative of the entire population, leading to incorrect conclusions.
Types of Sampling Risk (ISA 530): Test of controls and Test of details.
How to Reduce Sampling Risk?
Increase sample size and select sample units randomly.
Steps in Constructing Samples
Key considerations include audit objective, population attributes, and error definition. Acceptable error rate is the maximum error rate that allows the auditor to conclude the objective is still met.
For controls: Rate of deviation from a control procedure that is tolerable. For substantive tests: Maximum monetary error acceptable in account balances.
Sampling Approaches for Large Populations
For homogeneous data: Non-statistical sampling and statistical sampling. For non-homogeneous populations: Focus on large or high-risk items and apply sampling techniques to smaller items.
What Are CAATs (Computer-Assisted Audit Techniques)?
Tools and techniques that assist auditors in analyzing large datasets, testing controls, and verifying transactions.
Examples include completeness checks, data validation, and analyzing journal entries.
Advantages of CAATs
Faster and more efficient analysis of large datasets, enables testing of 100% of transactions, and reduces human bias in sampling.
Challenges of CAATs
Requires significant investment and training, and potential to disrupt client systems if not handled carefully.
Data Analytics in Auditing
The examination of large datasets to identify patterns, trends, and anomalies.
Uses include analyzing populations and testing journal entries for unusual activity.
Limitations of Data Analytics
Requires professional judgment to interpret data, and auditors must ensure the relevance and reliability of data.
Completion and Review Procedures
To ensure all audit objectives are met and appropriate conclusions are drawn.
Common procedures include reviewing contingent liabilities and obtaining written representations from management.
What are Written Representations (ISA 580)?
Written assurances from management about the accuracy and completeness of financial statements.
Contents include acknowledgment of management’s responsibility and confirmation that all transactions have been recorded and that the fs are free from material errors or misstatements.Acknowledge responsibility for maintaining the system of internal control
and that there are no material irregularities by management or staff.
What are Subsequent Events (ISA 560)?
Events occurring after the balance sheet date but before the audit report that may impact the financial statements.
Types include adjusting events and non-adjusting events.
What is an assurance engagement, and how does it differ from an audit?
Assurance engagement: Provides an independent evaluation of financial or non-financial subject matter to enhance its reliability for users.
Difference: While audits focus on financial statements, assurance engagements may include other areas such as sustainability reports or compliance reviews.
Practical Example: Providing assurance on a company’s carbon emissions report for regulatory compliance.
What are the levels of assurance provided in engagements?
Reasonable Assurance: High but not absolute assurance, achieved through extensive procedures (e.g., audits).
Limited Assurance: Moderate assurance, based on inquiry and analytical review (e.g., reviews).
No Assurance: Findings reported without conclusions (e.g., agreed-upon procedures).
Practical Example:
Reasonable assurance: Full statutory audit of financial statements.
Limited assurance: Review engagement for interim financial statements.
What is a review engagement, and how does it differ from an audit?
Definition: A review engagement provides a limited level of assurance through inquiry and analytical procedures, rather than detailed testing.
Conclusion: Expressed as negative assurance (e.g., “Nothing has come to our attention to indicate material misstatement”).
Practical Example: Reviewing interim financial statements for a private company preparing for an initial public offering (IPO).
What are subsequent events according to ISA 560?
Subsequent events are defined as “events occurring between the date of the financial statements and the date of the auditor’s report, and facts that become known to the auditor after the date of the auditor’s report.” (ISA 560 para 5(e)).
A company’s financial statements are dated December 31, but a significant legal settlement occurs in January before the auditor issues their report.
Why are subsequent events important in an audit?
Subsequent events can introduce a risk of material misstatement if not properly considered. These events might affect the financial statements even if they occur after the reporting period.
A major customer declares bankruptcy after year-end, which could indicate the need for a bad debt provision in the financial statements.
What types of subsequent events may affect the financial statements?
Adjusting Events: Provide additional evidence about conditions that existed at the balance sheet date.
Non-Adjusting Events: Indicate conditions that arose after the balance sheet date and require disclosure.
Settlement of a court case confirming a liability.
A fire destroying inventory after year-end.
How can subsequent events lead to a risk of material misstatement?
If subsequent events are not identified and evaluated, material facts may be omitted or misrepresented in the financial statements. This could result in an inaccurate portrayal of the company’s financial position.
Failing to account for a major impairment of assets that becomes apparent after the balance sheet date.
What procedures should auditors perform to review subsequent events?
Review board and management meeting minutes for discussions of significant events. Enquire of management about subsequent transactions or events. Examine post-year-end transactions for unusual or significant entries. Review legal correspondence for updates on litigation or disputes. Assess whether events require adjustments or disclosures in the financial statements.
The auditor examines post-year-end sales returns to identify potential revenue recognition issues.
What actions should auditors take if they identify a material subsequent event?
For adjusting events, ensure appropriate adjustments are made to the financial statements. For non-adjusting events, verify that disclosures are adequate and clear. Consider the impact of the event on the auditor’s opinion and report.
Including a disclosure for a post-year-end acquisition that does not affect the financial position as of the balance sheet date.
What are contingent liabilities?
Potential obligations dependent on the outcome of uncertain future events (e.g., lawsuits, tax disputes).
What are commitments?
Agreements to future financial obligations that an entity has entered into (e.g., long-term contracts).
