Under ISA 520, which of the following is an essential feature of applying substantive analytical procedures?
- A) Always using an auditor's expert to generate data.
- B) Developing an expectation of recorded amounts or ratios and evaluating whether that expectation is sufficiently precise to identify a misstatement.
- C) Sending out 100% confirmation letters to all debtors.
- D) Only comparing current year revenue to current year tax expenses.
Show answer & explanation
Answer: B) Developing an expectation of recorded amounts or ratios and evaluating whether that expectation is sufficiently precise to identify a misstatement.
A core requirement of ISA 520 is that the auditor must develop an independent expectation of a figure or ratio, and assess whether that expectation is precise enough to flag a material misstatement when compared to the client's actual recorded figures.
Question 2
During the final review stage of an audit, the engagement partner performs analytical procedures. What is the primary objective of these procedures at this stage?
- A) To calculate the exact tax liability for the year.
- B) To assist in forming an overall conclusion as to whether the financial statements are consistent with the auditor's understanding of the entity.
- C) To verify the physical existence of non-current assets.
- D) To document the specific internal control weaknesses found during interim testing.
Show answer & explanation
Answer: B) To assist in forming an overall conclusion as to whether the financial statements are consistent with the auditor's understanding of the entity.
Analytical procedures performed near the end of the audit are meant to corroborate conclusions formed during the audit and ensure the financial statements as a whole make sense based on the auditor's cumulative knowledge.
Question 3
An auditor compares a client's current year gross profit margin of 45% against the prior year's margin of 28%. The client has not introduced new products or raised prices. How should the auditor proceed?
- A) Accept the improvement as a sign of excellent management performance.
- B) Assume the prior year financial statements were materially misstated and reissue the previous audit report.
- C) Inquire of management regarding the fluctuation, and perform additional procedures to corroborate their explanation.
- D) Immediately issue an adverse opinion due to obvious fraud.
Show answer & explanation
Answer: C) Inquire of management regarding the fluctuation, and perform additional procedures to corroborate their explanation.
If analytical procedures identify significant fluctuations or inconsistent relationships, ISA 520 mandates that the auditor must inquire of management and obtain sufficient appropriate evidence to verify management's responses.
Question 4
A junior auditor attempts to use substantive analytical procedures to predict the client's total rental expense for the year. He applies a flat 10% lease increase to the prior year's figure, concluding the minor variance is immaterial. What crucial factor did he likely fail to consider?
- A) The color of the lease contracts.
- B) The reliability and disaggregation of data, such as newly opened or recently closed store locations during the year.
- C) The total number of employees working at the company.
- D) The current market price of purchasing commercial real estate.
Show answer & explanation
Answer: B) The reliability and disaggregation of data, such as newly opened or recently closed store locations during the year.
When developing an expectation, the auditor must ensure the underlying data is reliable and account for known operational changes. Simply applying a flat percentage increase ignores mid-year expansions or closures that fundamentally alter the expense.
Question 5
When assessing the reliability of data from which an expectation is developed for analytical procedures, which of the following provides the highest level of reliability?
- A) Data generated internally by a department with notoriously weak internal controls.
- B) Verbal estimates provided casually by the sales director.
- C) Information obtained from independent, reputable external sources, such as published industry averages.
- D) Broad, highly aggregated financial forecasts prepared five years ago.
Show answer & explanation
Answer: C) Information obtained from independent, reputable external sources, such as published industry averages.
Data is generally more reliable when it is obtained from independent sources outside the entity. Furthermore, data produced under strong internal controls is more reliable than data produced under weak controls.
Question 6
A client's trade payable days have drastically decreased from 55 days in the prior year to 25 days in the current year, despite no changes in supplier payment terms. What is the most likely risk indicated by this ratio?
- A) Overstatement of cash balances.
- B) Understatement of trade payables.
- C) Overstatement of inventory.
- D) Understatement of revenue.
Show answer & explanation
Answer: B) Understatement of trade payables.
A sudden, unexplained drop in payable days indicates that the liability might not be fully recorded at year-end. If purchases are occurring but the corresponding payables aren't booked, the payable days ratio drops artificially.
Question 7
An auditor identifies a massive increase in revenue just prior to the year-end, but a subsequent analytical review shows the receivables turnover days have spiked from 30 to 80 days. What combination of assertions is at highest risk here?
- A) Existence of inventory and classification of expenses.
- B) Occurrence of sales and valuation of trade receivables.
- C) Completeness of payables and presentation of equity.
- D) Rights and obligations of non-current assets.
Show answer & explanation
Answer: B) Occurrence of sales and valuation of trade receivables.
A late spike in revenue coupled with unpaid, aging receivables strongly suggests that fictitious sales may have been recorded (testing occurrence) or that these new debtors will not pay, threatening the recoverability of the asset (testing valuation).
Question 8
Which of the following best describes the concept of 'Directional Testing' in auditing?
- A) Testing assets only for understatement and liabilities only for overstatement.
- B) Testing assets and revenues primarily for overstatement, and testing liabilities and expenses primarily for understatement.
- C) Ensuring all audit testing proceeds strictly from January to December chronologically.
- D) Testing all transactions backwards from the ledger to the source document only.
Show answer & explanation
Answer: B) Testing assets and revenues primarily for overstatement, and testing liabilities and expenses primarily for understatement.
Directional testing focuses on management's typical biases. Management has an incentive to inflate profits and net assets, so auditors test assets/income for overstatement (existence/occurrence) and liabilities/expenses for understatement (completeness).
Question 9
If an auditor has assessed control risk in the payroll system as extremely low and tests of controls confirm they operate effectively, how does this impact substantive analytical procedures?
- A) Substantive analytical procedures become illegal to use.
- B) The auditor can place greater reliance on substantive analytical procedures, potentially reducing extensive detailed testing of transactions.
- C) The auditor must double the sample sizes for detailed testing regardless of the controls.
- D) The auditor must issue a disclaimer of opinion.
Show answer & explanation
Answer: B) The auditor can place greater reliance on substantive analytical procedures, potentially reducing extensive detailed testing of transactions.
When internal controls over a system are strong, the data produced by that system is highly reliable. Consequently, the auditor can confidently use substantive analytical procedures to gain assurance, reducing the need for heavy, line-by-line substantive testing.
Question 10
To perform a substantive analytical procedure on interest expense, an auditor multiplies the average outstanding bank loan balance by the contractual interest rate. What makes this a highly effective procedure?
- A) It completely eliminates the need to look at bank statements.
- B) The expectation developed (the calculated interest) is highly precise and based on reliable external data (contractual rates).
- C) It allows the auditor to charge a higher audit fee.
- D) It relies entirely on management's verbal estimations.
Show answer & explanation
Answer: B) The expectation developed (the calculated interest) is highly precise and based on reliable external data (contractual rates).
Interest expense is highly predictable when loan balances and rates are known. Because the expectation is precise, any significant deviation from the client's recorded expense immediately flags a likely misstatement.
