- You are performing a review engagement for a nonissuer. Management's draft financial statements include a large increase in gross margin, and the controller explains it is due to improved purchasing terms; supporting documentation is limited to an internal spreadsheet summarizing vendor rebates. The entity's rebate programs are complex and historically prone to cutoff errors. What is the most appropriate method for ensuring evidence sufficiency in this review engagement?
Answer: Perform additional inquiries and analytical procedures, including obtaining and reading significant rebate agreements and reconciling the rebate accrual to vendor statements where available.
This question tests AR-C Section 90, which governs review engagements for nonissuers and requires obtaining sufficient evidence through inquiry and analytics. The key facts include a large gross margin increase attributed to rebates, limited documentation, and historical cutoff errors in complex programs. Option B aligns with AR-C 90 by requiring additional procedures like inspecting agreements and reconciling accruals for corroboration beyond inquiry. Option A is incorrect as AR-C 90 mandates sufficient evidence, not expansion to audit-level testing; Option C is wrong because AR-C 90 requires corroboration for significant fluctuations; Option D is incorrect under AR-C 90 as direct bank communication is not standard and bypasses management. Options A, C, and D fail to ensure evidence appropriateness. A transferable framework is to corroborate explanations for unusual fluctuations with documentary evidence in reviews. Auditors should scale procedures based on risk, prioritizing external or independent support for high-risk areas.
- You are conducting an audit of an issuer. The company recognizes significant revenue from subscription contracts processed through an automated billing platform, and management provides a report summarizing deferred revenue rollforward. You noted deficiencies in change management over billing rate tables and incomplete audit trails for manual overrides. Which procedure provides the most reliable evidence over the completeness and accuracy of the deferred revenue rollforward?
Answer: Reperform the rollforward using data extracted independently from the billing platform and reconcile totals to the general ledger, with test checks to underlying contract terms.
This question tests PCAOB AS 2301, which requires auditors of issuers to obtain sufficient appropriate evidence for significant estimates like deferred revenue. The key facts involve deficiencies in change management over billing rates and incomplete audit trails for overrides in an automated system. Option B aligns with AS 2501 by requiring reperformance using independently extracted data and reconciliation to the general ledger, ensuring accuracy and completeness through test checks to contracts. Option A is incorrect as AS 2405 states management representations are not a substitute for substantive procedures; Option C is wrong because AS 2201 requires testing beyond inquiry for automated controls with risks; Option D is incorrect under AS 2110 as prior-year evidence does not suffice for current-period assertions. Options A, C, and D rely on less reliable evidence sources. A professional judgment framework is to independently verify system-generated reports in high-risk areas by reperforming calculations and tracing to source documents. This ensures evidence reliability by reducing dependence on potentially manipulated internal data.
- You are the auditor of a nonissuer in an audit. The company estimates an environmental remediation liability using an internal model and key assumptions (discount rate, probability of enforcement, and expected cleanup costs). Internal controls over the model are informal, and the assumptions are highly subjective. Which procedure provides the most reliable evidence for evaluating the reasonableness of the estimate?
Answer: Develop an independent expectation using an auditor's specialist and compare key assumptions to external data (regulatory correspondence, market discount rates, and third-party cost estimates).
This question tests AU-C Section 540, which requires auditors to obtain sufficient evidence for accounting estimates in nonissuer audits. The key facts include a highly subjective internal model for environmental liabilities with informal controls over assumptions. Option C aligns with AU-C 540 by developing an independent expectation using specialists and external data, ensuring reasonableness through corroboration. Option A is incorrect as AU-C 315 limits reliance on board minutes without substantive testing; Option B is wrong because AU-C 580 states representations are supplementary; Option D is incorrect under AU-C 540 as prior estimates do not address current-period changes. Options A, B, and D rely on less reliable internal evidence. A professional judgment rule is to use independent models and external benchmarks for subjective estimates. This framework helps auditors evaluate bias and achieve appropriate evidence for complex valuations.
- In a nonissuer audit, you are evaluating the allowance for credit losses. Management's model uses historical loss rates but did not adjust for a recent downturn affecting the entity's key customer base; internal controls over the model are limited. Which procedure provides the most reliable evidence to support the reasonableness of management's estimate?
Answer: Perform a retrospective review of prior estimates versus actual write-offs and develop an independent expectation incorporating current economic conditions and customer-specific risk.
This question tests AU-C Section 540, which requires evidence for credit loss allowances in nonissuer audits. The key facts include unadjusted historical rates despite downturns and limited controls. Option B aligns with AU-C 540 by performing retrospective reviews and independent expectations. Option A is incorrect as AU-C 540 requires current assessment; Option C is wrong because AU-C 580 limits representations; Option D is incorrect under AU-C 330 as estimates require testing. Options A, C, and D lack independence. A rule is to incorporate external factors in estimate testing. Auditors should use hindsight analysis for reasonableness.
- Which of the following forms of audit evidence is generally considered the most reliable?
Answer: A positive accounts receivable confirmation received directly by the auditor from a third party.
The correct answer is A. The reliability of audit evidence is influenced by its source and nature. Evidence is generally more reliable when it is obtained from independent sources outside the entity, obtained directly by the auditor, and exists in documentary form. A positive confirmation received directly by the auditor from a customer meets all these criteria.
B is incorrect because a sales invoice is internal documentation.
C is incorrect because verbal responses are less reliable than written evidence and are from an internal source.
D is incorrect because a photocopy provided by the client is less reliable than an original document obtained directly by the auditor from the external party (the bank).
- In a nonissuer audit, you plan to use sampling to test the occurrence of sales transactions. The client has many small-dollar sales and a few large, manual invoices processed outside the standard system workflow; controls over manual invoices are weak. Which factor would most likely affect the auditor's assessment of evidence sufficiency?
Answer: The presence of a small number of high-risk, large manual invoices may require targeted testing (100% examination) in addition to sampling the routine population.
This question tests AU-C Section 530, which addresses sampling in nonissuer audits for transaction testing. The key facts include weak controls over large manual invoices separate from routine processes. Option B aligns with AU-C 530 by requiring targeted testing for high-risk items beyond general sampling. Option A is incorrect as AU-C 530 requires risk-based approaches, not uniform methods; Option C is wrong because AU-C 315 assesses risk objectively; Option D is incorrect under AU-C 530 as automation does not reduce testing for high-risk items. Options A, C, and D ignore stratification. A judgment rule is to stratify populations by risk for effective sampling. This ensures sufficient evidence for heterogeneous transaction classes.
- Which of the following statements best describes the relationship between the sufficiency and appropriateness of audit evidence?
Answer: The quantity of audit evidence needed is affected by its quality; higher quality may require less quantity.
The correct answer is D. Sufficiency is the measure of the quantity of audit evidence, and appropriateness is the measure of its quality (relevance and reliability). There is an inverse relationship between the two. If the evidence an auditor obtains is of very high quality (highly appropriate), the auditor may be able to obtain sufficient evidence with a smaller sample size or fewer procedures.
A and B are incorrect as they misstate the inverse relationship.
C is incorrect because it confuses the definitions of sufficiency and appropriateness.
- You are performing an audit of a nonissuer with significant cash disbursements. The entity's accounts payable clerk prepares vendor master file changes and also processes payments; management provides an internal report listing vendor changes and asserts it is complete. Which factor would most likely affect the auditor's assessment of evidence sufficiency?
Answer: The lack of segregation of duties increases risk of unauthorized vendor changes, requiring more persuasive evidence (e.g., independent approval and corroboration) to support assertions.
This question tests AU-C Section 500, which requires assessing audit evidence sufficiency in nonissuer audits. The key facts include lack of segregation in vendor changes and payments, with a potentially incomplete internal report. Option B aligns with AU-C 315 by recognizing increased risk necessitating more persuasive evidence like independent approvals. Option A is incorrect as AU-C 500 focuses on content reliability, not format; Option C is wrong because AU-C 230 prioritizes evidence over deadlines; Option D is incorrect under AU-C 300 as future changes do not affect current evidence. Options A, C, and D ignore risk factors. A judgment framework is to increase evidence persuasiveness in areas with segregation weaknesses. Auditors should evaluate control deficiencies and adjust substantive testing accordingly.
- During an issuer audit, you identify a significant unusual transaction near year-end: the company sold receivables to a related party with recourse. Management provides the executed agreement and an internal memo concluding sale accounting is appropriate. Which procedure provides the most reliable evidence to support the presentation and disclosure assertions?
Answer: Obtain direct confirmation from the related party of key terms (including recourse), inspect cash settlement, and evaluate whether the transaction meets the criteria for sale accounting and related-party disclosure.
This question tests PCAOB AS 2505, which requires evidence for related-party transactions in issuer audits. The key facts include a significant unusual transaction with recourse, supported by internal documents. Option B aligns with AS 2410 by confirming terms externally and evaluating accounting criteria. Option A is incorrect as AS 1105 requires testing beyond memos; Option C is wrong because AS 2110 includes classification in scope; Option D is incorrect under AS 2805 as SEC communication is not for accounting judgments. Options A, C, and D undervalue external evidence. A transferable rule is to corroborate related-party terms with direct confirmations. Auditors should assess substance over form using independent evidence.
- In an issuer audit, you are testing operating effectiveness of controls over revenue recognition. Management provides screenshots showing that a control owner reviewed exception reports each month, but the screenshots do not show the report parameters, population, or evidence of follow-up. Based on the circumstances, which response is most appropriate for evaluating evidence reliability?
Answer: Obtain the underlying exception reports directly from the system (or from an IT-controlled repository), verify report parameters and completeness, and inspect evidence of investigation and resolution of exceptions.
This question tests PCAOB AS 2201, which requires testing operating effectiveness of controls in issuer audits, including evidence of performance. The key facts involve screenshots lacking details on parameters, population, or follow-up for revenue exception reports. Option B aligns with AS 1105 by requiring direct access to reports and verification of completeness and resolution, enhancing evidence reliability. Option A is incorrect as AS 1215 notes electronic evidence must be assessed for reliability; Option C is wrong because AS 2201 requires more than inquiry for detective controls; Option D is incorrect under AS 2110 as deferral ignores current-period testing needs. Options A, C, and D undervalue corroboration. A transferable framework is to verify the full control cycle, including inputs and outputs, for system-generated evidence. Auditors should prioritize direct inspection over representations in control testing.
- In an issuer audit, you obtained evidence about litigation contingencies through inquiry of management and review of internal legal summaries prepared by the general counsel. Management is reluctant to authorize a legal letter to external counsel, stating it is unnecessary. What is the most appropriate method for ensuring evidence sufficiency regarding completeness of litigation and claims?
Answer: Request management to authorize inquiry of external legal counsel; if management refuses, evaluate the effect as a scope limitation and consider the impact on the audit opinion.
This question tests PCAOB AS 2505, which requires inquiry of legal counsel for litigation in issuer audits. The key facts include management's reluctance to authorize external inquiry, limiting completeness evidence. Option B aligns with AS 2505 by requesting authorization and evaluating scope limitations under AS 2805. Option A is incorrect as AS 2505 requires external corroboration; Option C is wrong because AS 2505 prohibits unauthorized communication; Option D is incorrect under AS 2805 as uncertainty does not justify unmodified opinions without evidence. Options A, C, and D ignore scope issues. A judgment rule is to pursue external legal confirmations and assess refusals as limitations. This ensures sufficient evidence for contingent liabilities.
- You are auditing an issuer and testing the completeness of related-party disclosures. Management provides a list of related parties and states there are no others; you identified several significant payments to a consulting firm not on the list, and the vendor address matches an officer's home city. Based on the circumstances, which response is most appropriate for evaluating evidence reliability?
Answer: Perform additional procedures such as searching vendor master data for matches to officer information, reviewing conflict-of-interest disclosures, and inspecting contracts and board minutes to corroborate related-party relationships.
This question tests PCAOB AS 2410, which requires procedures for related-party completeness in issuer audits. The key facts include an incomplete management list and suspicious payments. Option B aligns with AS 2410 by performing searches and inspections for corroboration. Option A is incorrect as AS 2410 requires independent verification; Option C is wrong because AS 2505 mandates disclosure regardless of materiality; Option D is incorrect under AS 2805 as exchange communication is not standard. Options A, C, and D undervalue procedures. A framework is to use data matching and document reviews for undisclosed parties. Auditors should supplement lists with risk-based testing for completeness.
- An auditor makes inquiries of the warehouse manager regarding obsolete inventory. The manager states that all inventory is current and saleable. To evaluate the sufficiency and appropriateness of this oral evidence, the auditor should:
Answer: Corroborate the manager's statement by performing other procedures, such as analyzing inventory turnover and sales data.
The correct answer is C. Inquiry of client personnel provides important audit evidence, but it is generally not sufficient on its own to support a conclusion. The auditor must corroborate the information obtained through inquiry by performing other audit procedures. Analyzing inventory turnover, reviewing subsequent sales, and physically inspecting inventory for signs of obsolescence would be appropriate corroborating procedures.
A and D are incorrect because inquiry alone is never sufficient.
B is an improvement over oral evidence but is still an internal representation that requires corroboration.
- An auditor decides to use negative accounts receivable confirmations. This form of evidence is considered less persuasive than positive confirmations. Negative confirmations may be considered sufficient and appropriate only when certain conditions are met, including:
Answer: The assessed level of risk of material misstatement is low and the population comprises many small, homogeneous balances.
The correct answer is D. Auditing standards specify that negative confirmations may be used as the sole substantive audit procedure only when all of the following conditions are present: (1) the risk of material misstatement is assessed as low, (2) the population consists of a large number of small, homogeneous balances, (3) a very low exception rate is expected, and (4) the auditor has no reason to believe that recipients will disregard the requests.
A, B, and C describe the opposite conditions under which negative confirmations would be inappropriate.
- In a financial statement audit of a nonissuer, you obtained audit evidence about subsequent events through the report date. Two days before the planned report release, you learn from a news article that the client's largest customer filed for bankruptcy before year-end, but management asserts the article is inaccurate and asks you to ignore it. What type of evidence should the auditor prioritize to address the potential impact on accounts receivable valuation?
Answer: External evidence corroborating the customer's financial condition (for example, bankruptcy filings, direct communication/confirmation with the customer or trustee, and subsequent cash receipts), and evaluate the need to adjust the allowance.
AU-C 560 requires auditors to perform procedures to identify subsequent events requiring adjustment or disclosure, and to obtain sufficient appropriate evidence when such events are identified. The key fact is learning about a major customer's potential bankruptcy before year-end but after fieldwork, with management disputing the information. External evidence corroborating the customer's financial condition such as bankruptcy filings, direct confirmation, and subsequent receipts analysis (Option A) provides the most reliable evidence to resolve the conflicting information and determine necessary adjustments. Option B relies on management's oral explanation which is insufficient given the contradiction; Option C suggests the article alone is sufficient without corroboration; Option D misunderstands that representations cannot substitute for substantive evidence on known issues. When subsequent event information conflicts with management assertions, independent corroboration is essential. The professional judgment framework is: for subsequent events affecting asset valuation, prioritize external corroborating evidence over management explanations, especially when information sources conflict.
- An auditor determines that the risk of material misstatement for the revenue cycle is high. This assessment will most likely cause the auditor to:
Answer: Increase the quantity of audit evidence gathered for revenue accounts.
The correct answer is C. According to the audit risk model, a higher assessed risk of material misstatement requires the auditor to achieve a lower level of detection risk. This is accomplished by performing more persuasive audit procedures, which often means increasing the quantity (sufficiency) and quality (appropriateness) of audit evidence.
A is incorrect because while the auditor might decrease performance materiality, the most direct effect is on the amount of evidence needed.
B is incorrect because a high risk of material misstatement implies that internal controls are not effective or cannot be relied upon.
D is incorrect because while the auditor might shift from analytical procedures to more detailed tests, they could also decide to use more robust and precise analytical procedures; reducing them without a corresponding increase in other tests would be inappropriate.
- You are performing an audit of a nonissuer and are evaluating evidence over revenue. The client implemented a new point-of-sale system midyear; IT general controls over program changes are not effectively designed, but the system produces detailed sales reports used by management. Based on the circumstances, which response is most appropriate for evaluating evidence reliability from the system-generated sales reports?
Answer: Test the completeness and accuracy of the underlying data and relevant IT/application controls, or obtain corroborating evidence from independent sources (for example, shipping documents and cash receipts).
AU-C 500 requires auditors to evaluate the reliability of information produced by the entity's information system, considering both the source and nature of the information and the circumstances under which it is obtained. The critical fact is that IT general controls over program changes are not effectively designed, which directly impacts the reliability of system-generated reports. Testing the completeness and accuracy of underlying data and relevant IT/application controls, or obtaining corroborating evidence (Option C), properly addresses the reliability concerns by either establishing confidence in the system or finding alternative evidence. Option A incorrectly assumes management's use validates reliability; Option B wrongly equates electronic generation with accuracy when controls are weak; Option D misunderstands that both GAAS and PCAOB standards require appropriate evidence reliability regardless of issuer status. When IT general controls are weak, auditors must either test the specific reports used as evidence or corroborate with independent sources. The decision rule is: when relying on system-generated information with weak IT controls, always test completeness/accuracy of the specific reports or obtain corroborating evidence from independent sources.
- In a nonissuer financial statement audit, the entity received a significant government grant with allowable cost requirements. Management provides an internal schedule of costs charged to the grant and asserts compliance; controls over cost allocation are manual and not well documented. Which procedure provides the most reliable evidence regarding whether charged costs were allowable under the grant terms?
Answer: Inspect the grant agreement for allowable costs and test a sample of charged costs to third-party invoices, payroll records, and allocation support, evaluating consistency with the grant terms.
This question tests AU-C Section 330, which requires substantive procedures for grant compliance in nonissuer audits. The key facts include allowable cost requirements, internal schedules, and undocumented manual controls. Option B aligns with AU-C 500 by inspecting agreements and testing samples to external records. Option A is incorrect as AU-C 330 requires detailed testing; Option C is wrong because AU-C 500 states inquiry is insufficient; Option D is incorrect under AU-C 315 as absence of grantor audit does not prove compliance. Options A, C, and D lack substantiation. A transferable rule is to trace costs to source documents against criteria. Auditors should prioritize external evidence for compliance assertions.
- A company's internal audit function (IAF) provides the external auditor with a report detailing the results of its inventory cycle counts. Before using this report as audit evidence, the external auditor must evaluate the IAF's competence and objectivity. To evaluate the IAF's objectivity, the external auditor would be most interested in:
Answer: The organizational level to which the head of the internal audit function reports.
The correct answer is B. Objectivity relates to the internal auditors' ability to perform their tasks without bias. The most significant factor influencing objectivity is the organizational status of the IAF, specifically the level to which they report. Reporting to those charged with governance (e.g., the audit committee) rather than to operational management enhances the IAF's objectivity.
A, C, and D are all factors that relate primarily to the IAF's competence, not its objectivity.
- In an audit of a nonissuer, you are testing the valuation of a complex Level 3 investment measured at fair value. Management provides a valuation memo prepared by an outside specialist engaged and paid by the company, and the memo includes unobservable inputs that significantly affect the estimate. Based on the circumstances, which response is most appropriate for evaluating evidence reliability?
Answer: Evaluate the specialist's competence and objectivity, understand the methods and significant assumptions used, and, if needed, develop an independent estimate or involve the auditor's specialist.
AU-C 500 addresses using the work of management's specialist and requires auditors to evaluate the competence, capabilities, and objectivity of the specialist, as well as understand their work sufficiently to use it as audit evidence. The key fact is a Level 3 investment with unobservable inputs valued by a management-engaged specialist, creating both complexity and potential bias concerns. Evaluating the specialist's competence and objectivity, understanding methods and assumptions, and potentially developing an independent estimate (Option B) properly addresses the reliability concerns for this complex estimate. Option A fails to consider potential bias and assumption reasonableness; Option C inappropriately relies on representations for complex estimates; Option D misunderstands that using management's specialist doesn't impair auditor independence. For Level 3 fair values, professional skepticism requires thorough evaluation of specialist work. The decision framework is: when auditing complex estimates prepared by management's specialist, always evaluate competence/objectivity, understand and test key assumptions, and consider developing an independent estimate or engaging an auditor's specialist for material amounts.
