Question 1The purpose, scope and regulation of external audit and assurance engagements

What is the primary purpose of an external audit of a company's financial statements?

  1. To detect every instance of fraud within the company
  2. To prepare the financial statements on behalf of management
  3. To guarantee that the company will remain a going concern
  4. To provide an independent opinion on whether the financial statements are fairly presented Correct answer.

Explanation

An external audit gives an independent opinion on whether the financial statements are prepared, in all material respects, in accordance with the applicable reporting framework. It is not a guarantee of solvency, nor does it involve preparing the statements or detecting all fraud.

Question 2The purpose, scope and regulation of external audit and assurance engagements

Which concept describes the level of assurance that an external audit provides?

  1. No assurance
  2. Limited assurance
  3. Absolute assurance
  4. Reasonable assurance Correct answer.

Explanation

An audit provides reasonable assurance, which is a high but not absolute level of assurance. Absolute assurance is unattainable because of inherent limitations such as sampling and judgement.

Question 3The purpose, scope and regulation of external audit and assurance engagements

In an audit engagement, who is responsible for maintaining the accounting records and preparing the financial statements?

  1. The external auditor
  2. The external regulator
  3. The company's management Correct answer.
  4. The audit committee

Explanation

Management is responsible for preparing the financial statements and maintaining adequate accounting records. The auditor's role is to express an opinion on those statements, not to prepare them.

Question 4The purpose, scope and regulation of external audit and assurance engagements

Which of the following best describes the 'expectation gap' in auditing?

  1. The time lag between the year-end and the issue of the audit report
  2. The difference between the auditor's fee and the actual cost of the audit
  3. The gap between the draft and final versions of the audit report
  4. The difference between what the public expects auditors to do and what auditors actually do Correct answer.

Explanation

The expectation gap is the difference between the public's perception of an auditor's responsibilities and the auditor's actual duties. It often arises because the public overestimates the assurance an audit provides.

Question 5The purpose, scope and regulation of external audit and assurance engagements

Which type of engagement provides limited assurance rather than reasonable assurance?

  1. An agreed-upon procedures engagement
  2. A compilation engagement
  3. A review engagement Correct answer.
  4. Statutory audit

Explanation

A review engagement provides limited assurance, expressed as a conclusion on whether anything has come to the reviewer's attention. It involves less work than an audit and gives a lower level of assurance.

Question 6The purpose, scope and regulation of external audit and assurance engagements

In an agreed-upon procedures engagement, what level of assurance is provided?

  1. Absolute assurance
  2. Limited assurance
  3. No assurance Correct answer.
  4. Reasonable assurance

Explanation

An agreed-upon procedures engagement provides no assurance. The practitioner simply reports factual findings based on specified procedures, and users draw their own conclusions.

Question 7The purpose, scope and regulation of external audit and assurance engagements

Which body is responsible for issuing International Standards on Auditing (ISAs)?

  1. The Financial Reporting Council (FRC)
  2. The International Accounting Standards Board (IASB)
  3. The International Auditing and Assurance Standards Board (IAASB) Correct answer.
  4. The International Federation of Accountants (IFAC)

Explanation

The IAASB develops and issues ISAs, which set the standards for audit engagements. The IASB issues accounting standards, and the FRC issues standards in the UK context.

Question 8The purpose, scope and regulation of external audit and assurance engagements

Which of the following is an inherent limitation of an audit?

  1. The requirement for the auditor to be independent
  2. The need for the auditor to issue a written report
  3. The use of sampling and the exercise of professional judgement Correct answer.
  4. The requirement for the auditor to be a member of a professional body

Explanation

Audits rely on sampling and professional judgement, which means they cannot provide absolute assurance. Independence, reporting and membership requirements are features of an audit, not inherent limitations.

Question 9The purpose, scope and regulation of external audit and assurance engagements

Which of the following engagements is an assurance engagement?

  1. Preparing a tax return for a client
  2. Auditing a company's greenhouse gas emissions statement Correct answer.
  3. Performing a due diligence review for an acquisition
  4. Providing bookkeeping services

Explanation

An assurance engagement involves a practitioner expressing a conclusion to enhance confidence in information. Auditing a greenhouse gas statement is an assurance engagement on non-financial information.

Question 10The purpose, scope and regulation of external audit and assurance engagements

Under the 'three-party relationship' in an assurance engagement, who are the three parties?

  1. The auditor, the tax authority and the bank
  2. The client, the regulator and the shareholder
  3. The management, the employees and the auditor
  4. The practitioner, the responsible party and the intended users Correct answer.

Explanation

Every assurance engagement involves a practitioner, a responsible party (who prepares the subject matter) and intended users. This three-party relationship distinguishes assurance from other services.

Question 11The purpose, scope and regulation of external audit and assurance engagements

Which of the following is a benefit of an external audit to shareholders?

  1. It removes the need for management to keep accounting records
  2. It provides independent assurance that the financial statements can be relied upon Correct answer.
  3. It guarantees a dividend will be paid
  4. It ensures the company pays the lowest possible tax

Explanation

An audit gives shareholders independent assurance on the reliability of the financial statements, helping reduce information risk. It does not guarantee dividends, remove record-keeping duties or minimise tax.

Question 12The purpose, scope and regulation of external audit and assurance engagements

What does 'true and fair view' mean in the context of an audit opinion?

  1. The financial statements are free from all errors
  2. The financial statements have been approved by the tax authority
  3. The financial statements are prepared using only cash accounting
  4. The financial statements are prepared in accordance with the applicable framework and reflect economic reality Correct answer.

Explanation

A true and fair view means the financial statements are prepared in accordance with the applicable reporting framework and present the entity's position fairly. It does not mean the statements are entirely free from error.

Question 13The purpose, scope and regulation of external audit and assurance engagements

Which of the following is a regulatory source that governs the conduct of statutory audits in many jurisdictions?

  1. The company's internal control manual
  2. The payroll procedures of the client
  3. Company legislation and auditing standards Correct answer.
  4. The marketing policy of the audit firm

Explanation

Statutory audits are governed by company legislation and by auditing standards issued by recognised standard-setters. Internal manuals and client policies do not regulate the audit itself.

Question 14The purpose, scope and regulation of external audit and assurance engagements

What is the role of the Financial Reporting Council (FRC) in relation to audit in the UK?

  1. To act as the external auditor for all public companies
  2. To set auditing and ethical standards and oversee audit quality Correct answer.
  3. To collect taxes from audit firms
  4. To prepare financial statements for listed companies

Explanation

The FRC is the UK regulator responsible for setting auditing and ethical standards and overseeing the quality of audit work. It does not prepare statements, conduct audits or collect taxes.

Question 15The purpose, scope and regulation of external audit and assurance engagements

Which of the following best explains why auditor independence is important?

  1. It allows the auditor to set the client's accounting policies
  2. It enables the auditor to give an objective and unbiased opinion Correct answer.
  3. It allows the auditor to share fees with the client
  4. It guarantees the auditor will find all material misstatements

Explanation

Independence allows the auditor to form an objective, unbiased opinion free from influences that could compromise judgement. It does not allow setting policies, guarantee detection of all misstatements or permit fee-sharing.

Question 16The purpose, scope and regulation of external audit and assurance engagements

A company is required by law to have its financial statements audited. Which term best describes this type of audit?

  1. An internal audit
  2. A forensic audit
  3. A value-for-money audit
  4. A statutory audit Correct answer.

Explanation

A statutory audit is one required by legislation, such as the Companies Act. Internal, forensic and value-for-money audits are not mandated by company law in the same way.

Question 17The purpose, scope and regulation of external audit and assurance engagements

Which of the following distinguishes an assurance engagement from a consulting engagement?

  1. The practitioner prepares the client's financial statements
  2. The practitioner provides advice to improve the client's business
  3. The practitioner is paid a fee for the work
  4. The practitioner expresses a conclusion on a subject matter against suitable criteria Correct answer.

Explanation

An assurance engagement involves expressing a conclusion on a subject matter evaluated against suitable criteria, whereas consulting provides advice. Both may involve fees, but only assurance gives an independent conclusion.

Question 18The purpose, scope and regulation of external audit and assurance engagements

Which of the following is an example of a subject matter suitable for an assurance engagement?

  1. The personal tax affairs of the auditor
  2. The marketing budget of the audit firm
  3. The effectiveness of a company's internal control over financial reporting Correct answer.
  4. The auditor's own opinion on last year's audit

Explanation

Assurance can be provided on various subject matters, including the effectiveness of internal controls, provided suitable criteria exist. The auditor's own opinion, personal affairs and firm budgets are not appropriate subject matters.

Question 19The purpose, scope and regulation of external audit and assurance engagements

What does the term 'reasonable assurance' mean in an audit report?

  1. A high level of assurance that the financial statements are free from material misstatement Correct answer.
  2. A certainty that all transactions have been tested
  3. A moderate level of assurance sufficient for a review engagement
  4. A guarantee that no fraud exists

Explanation

Reasonable assurance is a high level of assurance that the financial statements are free from material misstatement. It is not a guarantee of no fraud, is higher than review assurance and does not require testing all transactions.

Question 20The purpose, scope and regulation of external audit and assurance engagements

Which of the following is a key difference between internal audit and external audit?

  1. Internal audit prepares financial statements, while external audit prepares tax returns
  2. Internal audit reports to management or the board, while external audit reports to shareholders Correct answer.
  3. Internal audit is required by company law, while external audit is optional
  4. Internal audit provides absolute assurance, while external audit provides limited assurance

Explanation

Internal audit is an independent appraisal function within the entity, reporting to management or the board, while external audit reports to shareholders on the financial statements. Internal audit does not provide absolute assurance, and external audit is often statutory.

Question 21The purpose, scope and regulation of external audit and assurance engagements

Which of the following is a potential consequence for an auditor of failing to comply with auditing standards?

  1. A guaranteed increase in audit fees
  2. Exemption from future audits
  3. Automatic imprisonment without trial
  4. Regulatory sanctions and loss of professional reputation Correct answer.

Explanation

Non-compliance with auditing standards can lead to regulatory sanctions, disciplinary action and reputational damage. It does not lead to automatic imprisonment, higher fees or exemption from future work.

Question 22The purpose, scope and regulation of external audit and assurance engagements

Which of the following best explains why an audit is described as providing 'reasonable' rather than 'absolute' assurance?

  1. Because of inherent limitations such as sampling, judgement and the nature of evidence Correct answer.
  2. Because auditors are not qualified
  3. Because auditors are not independent
  4. Because auditors only check cash balances

Explanation

Inherent limitations, including the use of sampling, the exercise of judgement and the persuasive rather than conclusive nature of audit evidence, mean only reasonable assurance is possible. Auditors are qualified and independent, and they examine far more than cash.

Question 23The purpose, scope and regulation of external audit and assurance engagements

Which of the following is an example of a non-assurance service that an audit firm might provide?

  1. Assurance on a sustainability report
  2. Preparation of tax computations Correct answer.
  3. Review of interim financial information
  4. Statutory audit of financial statements

Explanation

Preparing tax computations is a non-assurance service because the firm does not express an independent conclusion on information. Audits, reviews and sustainability assurance all involve expressing a conclusion.

Question 24The purpose, scope and regulation of external audit and assurance engagements

Which of the following statements about the scope of an external audit is correct?

  1. The auditor must verify every transaction recorded by the company
  2. The auditor is required to assess the competence of all employees
  3. The auditor's scope is determined solely by the client's preferences
  4. The auditor plans and performs the audit to obtain sufficient appropriate evidence to reduce audit risk to an acceptably low level Correct answer.

Explanation

The auditor plans and performs the audit to obtain sufficient appropriate evidence to reduce audit risk to an acceptably low level. This does not require verifying every transaction or assessing all employees, and scope is governed by standards, not client preference alone.

Question 25The purpose, scope and regulation of external audit and assurance engagements

Which of the following is a key element that must be present for an engagement to qualify as an assurance engagement?

  1. Suitable criteria against which the subject matter is evaluated Correct answer.
  2. A requirement that the practitioner is also the client's bookkeeper
  3. An agreement that no report will be issued
  4. A guarantee that the subject matter is error-free

Explanation

An assurance engagement requires a three-party relationship, a subject matter, suitable criteria, sufficient appropriate evidence and a written conclusion. It does not require error-free subject matter, bookkeeping by the practitioner or the absence of a report.

Question 26The purpose, scope and regulation of external audit and assurance engagements

Which of the following best describes the primary objective of an external audit of financial statements?

  1. To prepare the financial statements on behalf of management
  2. To guarantee that the financial statements are free from all errors and fraud
  3. To provide an opinion on whether the financial statements are prepared, in all material respects, in accordance with the applicable financial reporting framework Correct answer.
  4. To assess the efficiency and effectiveness of the entity's operations

Explanation

The primary objective of an external audit is to express an opinion on whether the financial statements are prepared, in all material respects, in accordance with the applicable financial reporting framework. This provides reasonable assurance to users but is not a guarantee of absolute accuracy.

Question 27The purpose, scope and regulation of external audit and assurance engagements

Which of the following is the most appropriate description of the concept of 'auditor independence'?

  1. The auditor must not have any personal relationship with the client's employees
  2. The auditor must be independent in mind and appearance, free from influences that could compromise professional judgement Correct answer.
  3. The auditor must not provide any non-audit services to the client
  4. The auditor must rotate off the engagement every five years

Explanation

Independence requires both independence of mind (the ability to make unbiased decisions) and independence in appearance (the avoidance of circumstances that would lead a reasonable third party to doubt the auditor's objectivity). It is not limited to personal relationships or specific prohibitions.

Question 28The purpose, scope and regulation of external audit and assurance engagements

A firm is engaged to review the entity's internal controls over financial reporting and express a conclusion on their design and operating effectiveness. Which type of engagement is this?

  1. An assurance engagement Correct answer.
  2. A compilation engagement
  3. An agreed-upon procedures engagement
  4. A tax advisory engagement

Explanation

This engagement involves a three-party relationship, a subject matter (internal controls), suitable criteria, and the expression of a conclusion that provides intended users with a level of assurance. Therefore, it is an assurance engagement.

Question 29The purpose, scope and regulation of external audit and assurance engagements

Which of the following statements best explains why an external audit is subject to regulation and oversight by professional or statutory bodies?

  1. To guarantee that audited entities will not fail
  2. To increase the fees that auditors can charge
  3. To reduce the workload of the entity's management
  4. To protect the public interest by ensuring audits are conducted to consistent, high-quality standards Correct answer.

Explanation

Regulation and oversight exist to safeguard the quality and consistency of audit work, thereby protecting the public interest and maintaining confidence in financial reporting. They do not guarantee entity survival or affect fees directly.

Question 30The purpose, scope and regulation of external audit and assurance engagements

Which of the following best describes the relationship between International Standards on Auditing (ISAs) and national auditing standards in a jurisdiction that has adopted ISAs?

  1. National standards are only applicable to small entities
  2. National standards must be identical to ISAs without any modification
  3. National standards take precedence over ISAs in all cases
  4. National standards may add requirements but cannot reduce the requirements of ISAs Correct answer.

Explanation

When a jurisdiction adopts ISAs, it may supplement them with additional national requirements or guidance, but it cannot omit or contradict the requirements of ISAs. This ensures a consistent baseline of audit quality while allowing for local legal or regulatory needs.

Question 31Professional ethics, independence and the auditor's responsibilities

Which threat to auditor independence arises when an audit partner has a close family member employed as the financial controller of the audit client?

  1. Intimidation threat
  2. Familiarity threat Correct answer.
  3. Self-interest threat
  4. Advocacy threat

Explanation

A familiarity threat arises when close relationships make the auditor too sympathetic to the client's interests. A close family member in a senior financial role creates that sympathetic bias.

Question 32Professional ethics, independence and the auditor's responsibilities

An audit firm earns a significant proportion of its total fee income from a single audit client. Which threat does this most directly create?

  1. Self-interest threat Correct answer.
  2. Advocacy threat
  3. Intimidation threat
  4. Self-review threat

Explanation

Dependence on fees from one client gives the firm an interest in retaining that client, which is a self-interest threat. The significance of the total fee relative to the firm's income drives the concern.

Question 33Professional ethics, independence and the auditor's responsibilities

Which safeguard best addresses the self-review threat created when an audit firm's tax department prepares the calculations underlying a client's tax provision?

  1. Obtaining a management representation about the tax figure
  2. Requiring the client's staff to sign the tax computation
  3. Extending the audit to cover the tax computation twice
  4. Using a separate engagement team to review the tax work Correct answer.

Explanation

A self-review threat is reduced by having the audit work reviewed by personnel not involved in preparing the figures. Independence of the reviewing team preserves objectivity.

Question 34Professional ethics, independence and the auditor's responsibilities

Under fundamental ethical principles, an auditor who keeps confidential client information secure but discloses it when compelled by law is acting:

  1. Improperly, because the client must consent first
  2. Appropriately, only if the client is notified in advance
  3. Improperly, because confidentiality is absolute
  4. Appropriately, because disclosure required by law is permitted Correct answer.

Explanation

Confidentiality prohibits disclosure except where there is a legal or professional right or duty to disclose. Compulsion by law is a recognised exception.

Question 35Professional ethics, independence and the auditor's responsibilities

A client offers an audit senior tickets to a major sporting event shortly before the audit report is due to be signed. Which principle is most directly threatened?

  1. Professional competence and due care
  2. Confidentiality
  3. Professional behaviour
  4. Objectivity Correct answer.

Explanation

Accepting gifts can compromise objectivity by creating a sense of obligation to the client. The timing, close to signing, heightens the risk.

Question 36Professional ethics, independence and the auditor's responsibilities

Which of the following best describes the auditor's duty of confidentiality regarding information obtained during an audit?

  1. It applies only to information disclosed in writing
  2. It ends when the audit report is signed
  3. It continues after the auditor-client relationship ends Correct answer.
  4. It applies only to information marked confidential by the client

Explanation

The duty of confidentiality is continuing and survives the end of the engagement. It covers all client information acquired through the professional relationship.

Question 37Professional ethics, independence and the auditor's responsibilities

An audit firm is asked to accept an engagement where the previous auditor has not yet been properly removed and no communication has occurred. What should the firm do?

  1. Accept and inform the previous auditor after signing
  2. Accept but perform only limited procedures
  3. Accept and rely on the client's assurance
  4. Decline until the appointment is valid and professional communication is complete Correct answer.

Explanation

A successor auditor should not accept appointment until the predecessor's removal or resignation is properly effected and professional clearance is obtained. This protects the integrity of the appointment process.

Question 38Professional ethics, independence and the auditor's responsibilities

Which action is the most appropriate response when an auditor identifies a threat to independence that cannot be reduced to an acceptable level by safeguards?

  1. Decline or terminate the engagement Correct answer.
  2. Disclose the threat in the audit report and continue
  3. Increase the audit fee to compensate for the risk
  4. Document the threat and continue the engagement

Explanation

Where safeguards cannot eliminate or reduce a threat to an acceptable level, the auditor must decline or withdraw from the engagement. Continuing would compromise independence.

Question 39Professional ethics, independence and the auditor's responsibilities

An auditor is offered a non-audit service engagement that would involve making management decisions for the audit client. The auditor should:

  1. Accept, provided the work is reviewed by the client's finance director
  2. Accept, provided the service is performed by a separate department
  3. Decline, because assuming management responsibility creates an unacceptable threat Correct answer.
  4. Accept, provided the fee is disclosed to those charged with governance

Explanation

An auditor must not assume management responsibilities for an audit client, as this creates threats that cannot be safeguarded. Making management decisions is prohibited.

Question 40Professional ethics, independence and the auditor's responsibilities

Which of the following is a self-review threat?

  1. An auditor being threatened with removal by the client
  2. An auditor relying on a valuation the same firm prepared for the client Correct answer.
  3. An auditor having shares in the client
  4. An auditor promoting the client's shares to investors

Explanation

A self-review threat arises when the auditor evaluates work previously performed by the same firm. Relying on the firm's own valuation is a clear example.

Question 41Professional ethics, independence and the auditor's responsibilities

An audit partner has provided audit services to the same client for many years and has developed a close personal relationship with the finance director. Which safeguard is most appropriate?

  1. Reducing the scope of the audit
  2. Extending the audit deadline
  3. Increasing the audit fee
  4. Rotating the engagement partner Correct answer.

Explanation

Partner rotation is a recognised safeguard against familiarity threats arising from long association. It introduces fresh objectivity.

Question 42Professional ethics, independence and the auditor's responsibilities

Which of the following best describes the purpose of professional scepticism in an audit?

  1. Assuming management is dishonest until proven otherwise
  2. Accepting management explanations without further testing
  3. Applying the same procedures to every client
  4. Maintaining a questioning mind and being alert to contradictory evidence Correct answer.

Explanation

Professional scepticism means maintaining a questioning mind, being alert to conditions indicating possible misstatement, and critically assessing evidence. It is not an assumption of dishonesty.

Question 43Professional ethics, independence and the auditor's responsibilities

An auditor discovers that a client has breached money laundering regulations. Under professional duties, the auditor should:

  1. Report the matter to the appropriate authority as required by law Correct answer.
  2. Ignore the matter as it is outside the audit scope
  3. Only note the matter in the management letter
  4. Disclose the matter to the client's competitors

Explanation

Auditors have legal and professional obligations to report suspected money laundering to the relevant authorities. Confidentiality does not prevent disclosure required by law.

Question 44Professional ethics, independence and the auditor's responsibilities

Which of the following is an intimidation threat to auditor independence?

  1. The auditor prepared the client's accounting records
  2. The client threatens to remove the auditor if a particular accounting treatment is not accepted Correct answer.
  3. The auditor promotes the client's shares
  4. The auditor owns shares in the client

Explanation

An intimidation threat arises when the client applies pressure, such as threatening removal, to influence the auditor's judgement.

Question 45Professional ethics, independence and the auditor's responsibilities

An audit firm is considering providing internal audit services to an audit client. Which factor most affects whether this creates an unacceptable threat?

  1. The number of staff in the audit firm
  2. The size of the audit fee
  3. Whether the client has an effective audit committee and management oversight Correct answer.
  4. The length of the audit engagement letter

Explanation

The threat from providing internal audit to an audit client depends on whether management retains responsibility and oversight, including the presence of an effective audit committee.

Question 46Professional ethics, independence and the auditor's responsibilities

Which statement about the auditor's duty of confidentiality is correct?

  1. It applies only during the audit fieldwork period
  2. It permits disclosure to the auditor's spouse without restriction
  3. It prohibits disclosure in all circumstances
  4. It permits disclosure where there is a professional duty to do so Correct answer.

Explanation

Confidentiality permits disclosure where there is a legal or professional right or duty to disclose, such as under regulatory requirements.

Question 47Professional ethics, independence and the auditor's responsibilities

An auditor is asked to value a complex financial instrument for an audit client and the valuation will be material to the financial statements. The auditor should:

  1. Perform the valuation but disclose it in the audit report
  2. Perform the valuation and rely on it in the audit without further work
  3. Perform the valuation only if the fee is increased
  4. Decline the valuation because it creates a self-review threat that cannot be adequately safeguarded Correct answer.

Explanation

Where the auditor's valuation would be material and relied upon in the audit, the self-review threat cannot be reduced to an acceptable level. The auditor should not perform the valuation.

Question 48Professional ethics, independence and the auditor's responsibilities

Which of the following is an example of the advocacy threat?

  1. An auditor holding a loan from the client
  2. An auditor acting as an advocate for the client in a legal dispute Correct answer.
  3. An auditor reviewing the client's inventory count
  4. An auditor preparing the client's bank reconciliation

Explanation

An advocacy threat arises when the auditor promotes or defends the client's position, such as acting as an advocate in a dispute.

Question 49Professional ethics, independence and the auditor's responsibilities

The audit firm's policy requires that all threats to independence be documented and evaluated. This requirement is best described as:

  1. A quality control procedure Correct answer.
  2. A management representation
  3. An audit procedure
  4. A safeguard

Explanation

Documenting and evaluating threats is part of the firm's quality control system, which supports compliance with ethical requirements.

Question 50Professional ethics, independence and the auditor's responsibilities

An auditor who lacks the necessary expertise to audit a complex derivative should:

  1. Disclaim an opinion automatically
  2. Rely on the client's valuation without question
  3. Reduce the audit fee to reflect the risk
  4. Obtain the necessary competence, for example through training or an expert Correct answer.

Explanation

Professional competence and due care requires the auditor to attain the skills needed or use an expert. It does not permit relying blindly on the client.
