CPA Auditing and Attestation (AUD) › Substantive Procedures
During a nonissuer financial statement audit of a regional manufacturer, the auditor is testing the existence and valuation assertions for accounts receivable. Year-end gross receivables increased 28% while sales increased 6%, and days sales outstanding rose from 42 to 58; management attributes this to a new distributor program started late in the year. Which factor most likely requires additional investigation by the auditor?
Management’s explanation alone, provided verbally, which is sufficient appropriate evidence to conclude receivables are fairly stated
The significant increase in days sales outstanding relative to sales growth, suggesting potential collectibility issues or revenue cut-off concerns
The increase in receivables, which should be addressed only by testing controls over credit approval rather than performing substantive procedures
The fact that the entity is a nonissuer, which eliminates the need for substantive procedures over receivables under AICPA standards
Explanation
AU-C 330 requires auditors to design substantive procedures that respond to assessed risks and obtain sufficient appropriate audit evidence for relevant assertions. The significant increase in days sales outstanding (DSO) from 42 to 58 days, combined with receivables growing 28% while sales only grew 6%, represents a red flag requiring investigation as it suggests potential collectibility issues or revenue cut-off concerns. This disproportionate growth pattern could indicate premature revenue recognition, channel stuffing, or deteriorating credit quality that affects the valuation assertion. Option B is incorrect because nonissuers require substantive procedures over material accounts regardless of entity type (AU-C 330). Option C is incorrect because management explanations alone never constitute sufficient appropriate audit evidence without corroboration (AU-C 580). Option D is incorrect because control testing cannot replace substantive procedures when specific risks are identified. The professional judgment framework requires auditors to investigate significant unexplained fluctuations in key metrics, particularly when multiple indicators (DSO increase, receivables growth exceeding sales growth) point to potential misstatement risks.
During a nonissuer financial statement audit of a software company, the auditor is testing the occurrence and accuracy assertions for revenue. A large year-end sale was recorded on December 31, but the customer’s acceptance clause requires formal sign-off, and sign-off occurred on January 10; management states the contract was “substantially complete” at year-end. Based on the audit evidence, which conclusion is most appropriate?
Revenue recognition appears appropriate because the invoice date is December 31 and the amount is mathematically accurate
Revenue should be considered potentially misstated due to cut-off/occurrence issues, and additional procedures are needed to evaluate satisfaction of the acceptance provision
No further work is needed because acceptance clauses are a control issue rather than a substantive audit matter
The auditor should treat the client as an issuer and apply PCAOB AS 2410 requirements to conclude based solely on analytical procedures
Explanation
Under ASC 606 and AU-C 500, revenue recognition requires that control has transferred to the customer, and acceptance clauses can prevent control transfer until formal acceptance occurs. The fact that customer acceptance didn't occur until January 10 creates a potential cut-off error, as the performance obligation may not have been satisfied by December 31 despite management's assertion of substantial completion. The auditor must perform additional procedures to evaluate whether the acceptance provision is substantive or perfunctory and whether revenue recognition criteria were met at year-end. Option A is incorrect because the invoice date alone doesn't determine proper revenue recognition timing under ASC 606. Option C is incorrect because acceptance clauses directly affect the occurrence assertion and require substantive testing, not just control evaluation. Option D is incorrect because the entity is explicitly identified as a nonissuer, making PCAOB standards inapplicable. The professional judgment framework requires careful evaluation of contract terms, particularly acceptance provisions, to determine if performance obligations were satisfied and control transferred by the reporting date.
In a nonissuer financial statement audit of a wholesaler, the auditor is addressing the completeness assertion for accounts payable at year-end. The client has weak vendor statement reconciliation and has historically recorded invoices late; subsequent cash disbursements in January include several large payments to vendors not included in the year-end payable listing. Which substantive procedure should the auditor perform for this assertion?
Apply PCAOB confirmation requirements to obtain positive confirmations from all vendors regardless of risk assessment
Perform a search for unrecorded liabilities by examining subsequent cash disbursements and unmatched receiving reports around year-end
Rely primarily on management’s representation letter that all liabilities have been recorded
Inspect shipping documents for a sample of year-end sales to verify revenue recognition
Explanation
AU-C 330 requires auditors to design substantive procedures specifically responsive to the completeness assertion for liabilities, which is inherently difficult to test because unrecorded items leave no audit trail. Performing a search for unrecorded liabilities by examining subsequent cash disbursements and unmatched receiving reports is the appropriate procedure because it identifies payments made after year-end that may relate to goods or services received before year-end. The presence of large January payments to vendors not on the year-end listing strongly suggests completeness issues requiring this targeted search. Option A is incorrect because shipping document inspection tests the occurrence of revenue, not completeness of payables. Option C is incorrect because management representations cannot replace substantive procedures for material assertions (AU-C 580). Option D is incorrect because PCAOB standards don't apply to nonissuers, and blanket positive confirmations aren't required regardless of risk. The decision rule for completeness testing is to look beyond the recorded population using techniques like subsequent payment review, unmatched document searches, and analytical procedures to identify potentially omitted items.
An issuer technology company is audited under PCAOB standards. During substantive testing of revenue (occurrence and cutoff), the auditor identifies multiple sales recorded on the last day of the year with shipping documents dated two days after year-end and extended payment terms not in the master contract. What is the best response to identified misstatements?
Accept management’s explanation that the shipping documents were processed late and treat the items as trivial without further work
Propose an adjustment for the identified items and expand cutoff testing around year-end to determine whether misstatements are isolated or systemic
Communicate the issue only to the internal audit function and take no further audit action
Discontinue substantive testing and rely on management representations because PCAOB standards emphasize controls over revenue
Explanation
This question tests the auditor's response to misstatements under AS 2810 in a PCAOB audit, emphasizing evaluation and further procedures. Key facts include sales recorded prematurely with post-year-end shipping and non-standard terms, indicating cutoff and occurrence issues. Proposing adjustments and expanding cutoff testing aligns with AS 2810.12's requirement to accumulate and evaluate misstatements for systemic patterns. Accepting explanations without work (B) ignores AS 2401's fraud considerations, while discontinuing testing (C) violates AS 2301's substantive requirements. Communicating only to internal audit (D) bypasses AS 1301's governance reporting. A framework involves aggregating misstatements quantitatively and qualitatively, considering intent and pervasiveness. Professional judgment dictates extending procedures when errors suggest broader risks, ensuring adjustments reflect true economic substance.
An issuer retail chain is being audited under PCAOB standards. Preliminary analytics show accounts receivable days outstanding increased from 22 to 41 days, while revenue increased 4% and cash collections did not change materially. What is the most appropriate analytical procedure given the situation?
Conclude the increase is acceptable because revenue growth can naturally extend collection periods, and perform no further procedures
Develop an expectation for receivable turnover by store/region and credit terms, compare to recorded results, and investigate significant deviations
Perform tests of controls over credit approvals instead of additional substantive or analytical procedures
Perform analytical procedures only at the end of the audit because PCAOB standards do not permit analytics during planning
Explanation
This question evaluates the use of analytical procedures under AS 2305 for substantive testing of accounts receivable in a PCAOB audit. Key facts show receivable days outstanding doubling from 22 to 41 despite modest revenue growth and stable cash collections, suggesting potential overstatement or collection issues. Developing disaggregated expectations by store/region and credit terms, then investigating deviations, enhances precision as required by AS 2305.03 for effective analytics. Concluding the increase is acceptable without procedures (A) ignores AS 2810's evaluation requirements, while substituting control tests (C) does not address substantive needs per AS 2301. Analytical procedures are permitted throughout the audit (D), not just at the end, per AS 2105. A framework for analytics involves disaggregating data to improve reliability, always corroborating unexpected variances with other evidence. Professional judgment requires assessing whether trends align with economic factors, escalating to detailed testing when inconsistencies arise.
An issuer manufacturing company is audited under PCAOB standards. The auditor is confirming accounts receivable and receives several confirmations returned from a different mailing address than the one selected from the customer master file, with signatures that are illegible. Which factor most likely requires additional investigation by the auditor?
The confirmations were returned, which automatically provides sufficient evidence of existence
The discrepancy in return address and unclear respondent identity may indicate the responses are not from the intended confirming parties
Under PCAOB standards, confirmations must be negative confirmations for all balances
The auditor should treat the responses as exceptions and immediately issue an adverse opinion
Explanation
This question addresses confirmation reliability under AS 2310 in PCAOB audits for receivables. Key facts include mismatched return addresses and illegible signatures, questioning respondent identity. The discrepancies require investigation per AS 2310.29's guidance on verifying authenticity. Returns alone (A) are insufficient, while negative confirmations (C) are not required. Adverse opinions (D) are premature. Auditors must maintain confirmation control, using alternatives for unreliable responses. A decision rule is to scrutinize anomalies in responses, escalating to vouching or additional confirmations.
A nonissuer manufacturing company is undergoing a financial statement audit under AICPA standards. The auditor is testing the valuation assertion for inventory and notes that the inventory aging report shows $18.2$% of finished goods are older than 12 months (prior year $6.1$%), while gross margin is stable. Which substantive procedure should the auditor perform for this assertion?
Perform test counts at year-end solely to address the existence assertion for inventory quantities
Rely primarily on the audit committee’s oversight as a substitute for substantive testing of valuation
Obtain management’s representation that all obsolete items have been written down and reduce further testing
Select a sample of aged items and inspect subsequent sales and/or evaluate net realizable value to assess obsolescence reserves
Explanation
This question tests the auditor's responsibility under AU-C Section 501 to design substantive procedures responsive to risks related to the valuation assertion for inventory. The key facts include a significant increase in aged finished goods from 6.1% to 18.2% with stable gross margins, indicating potential obsolescence risk without corresponding valuation adjustments. Selecting a sample of aged items and evaluating net realizable value through subsequent sales aligns with ASC 330 guidance on lower of cost or NRV, providing direct evidence of valuation appropriateness. Performing test counts at year-end (A) addresses existence, not valuation, while obtaining management's representation without further testing (B) violates AU-C 500's requirement for sufficient appropriate evidence. Relying on audit committee oversight (D) is not a substantive procedure and ignores AU-C 240's emphasis on auditor responsibility for fraud risks. Auditors should always tailor procedures to specific assertions, ensuring valuation testing includes market-based evidence like subsequent dispositions. A useful decision rule is to escalate testing when analytical indicators like aging trends signal unadjusted risks, incorporating independent corroboration to mitigate bias.
During a nonissuer financial statement audit, the auditor identifies a likely misstatement in depreciation expense (valuation/accuracy) because a material asset was placed in service midyear but depreciation was recorded for a full year. Management proposes to waive adjustment because the misstatement is below overall materiality, but it would cause the debt service coverage ratio to fall below a covenant threshold if corrected. What is the best response to identified misstatements?
Apply PCAOB requirements for critical audit matters and issue a CAM paragraph instead of requesting an adjustment
Waive the adjustment because it is below overall materiality and qualitative factors are not relevant to misstatement evaluation
Treat the misstatement as potentially material due to qualitative factors (covenant impact) and request adjustment or consider implications for the opinion if not corrected
Document the misstatement but take no further action because covenant compliance is a matter for management, not the auditor
Explanation
AU-C 450 requires auditors to evaluate misstatements considering both quantitative and qualitative factors, with particular attention to items affecting compliance with regulatory requirements or debt covenants. A misstatement that causes covenant violation represents a significant qualitative factor that can make an otherwise quantitatively immaterial item material to users' decisions. The auditor should request correction of the misstatement or, if management refuses, consider the implications for the audit opinion including potential emphasis-of-matter paragraphs or opinion modification. Option A is incorrect because qualitative factors are explicitly relevant to materiality evaluation under AU-C 320. Option C is incorrect because the auditor has a responsibility to evaluate all identified misstatements and their effects on the financial statements. Option D is incorrect because CAMs apply only to issuers under PCAOB standards, not nonissuers. The decision principle is that covenant impacts, earnings quality issues, and regulatory compliance effects can render quantitatively small misstatements material, requiring the same treatment as quantitatively material items.
In an issuer financial statement audit, the auditor is testing the valuation assertion for goodwill impairment. Management’s model shows no impairment, but key assumptions (discount rate and long-term growth rate) are at the most optimistic end of industry ranges and small changes would result in impairment; management refuses to provide sensitivity analyses. Which substantive procedure should the auditor perform for this assertion?
Rely on management’s point estimate because estimates are inherently subjective and cannot be audited with substantive procedures
Perform a retrospective review of prior-year cash flow forecasts versus actual results and develop an independent sensitivity analysis of key assumptions to evaluate potential impairment
Limit work to testing controls over the budgeting process and omit substantive procedures because the entity is an issuer
Wait until after the audit report is issued to assess impairment because subsequent market data is more reliable than year-end assumptions
Explanation
PCAOB AS 2502 requires auditors to evaluate the reasonableness of significant accounting estimates, including testing management's process and assumptions or developing an independent estimate. When management uses aggressive assumptions at the extreme end of reasonable ranges and refuses sensitivity analysis, the auditor must perform independent procedures including retrospective review of prior estimates and developing alternative scenarios. This approach provides evidence about management's estimation bias and the potential range of outcomes. Option B is incorrect because the subjectivity of estimates actually increases, not eliminates, the need for substantive audit procedures. Option C is incorrect because control testing cannot replace substantive procedures for significant estimates, especially for issuers where both are typically required. Option D is incorrect because goodwill impairment must be evaluated as of the balance sheet date, not deferred to post-report periods. The professional framework requires heightened skepticism and independent analysis when management's assumptions cluster at optimistic extremes and small changes would alter conclusions, as this pattern suggests potential bias requiring thorough substantive testing.
During a nonissuer financial statement audit, the auditor is evaluating the accuracy and occurrence assertions for cash receipts applied to accounts receivable. The auditor plans to use external confirmations but notes that many customers are small and historically do not respond; the client offers to email customers from the controller’s account to “speed responses.” Which conclusion is most appropriate regarding the reliability of the confirmation evidence?
Because this is a nonissuer, confirmations are prohibited and the auditor must rely only on inquiry and observation
Confirmation evidence is reliable regardless of control over requests as long as responses are received electronically
The auditor should maintain control over confirmation requests and responses; client-controlled emailing increases interception risk and reduces reliability
Allow the client to control the confirmation process because it increases response rates and does not affect evidence reliability
Explanation
AU-C 505 requires the auditor to maintain control over external confirmation requests throughout the confirmation process to ensure reliability of the evidence obtained. Allowing the client to control the emailing process, even from the controller's account, significantly increases the risk of interception, alteration, or misdirection of confirmations, thereby reducing evidence reliability. The auditor must send confirmations directly to the confirming party and receive responses directly to maintain the integrity of the process. Option A is incorrect because client control compromises evidence reliability regardless of response rates. Option B is incorrect because electronic responses don't eliminate the need for auditor control over the process; in fact, electronic confirmations may require additional verification procedures. Option D is incorrect because confirmations are a key substantive procedure for nonissuers and are not prohibited. The professional principle is that external confirmation reliability depends on the auditor maintaining control from request through response, and any client involvement in the communication process undermines this reliability.
