a. Elements of an assurance engagement (10 Marks)
The elements of an assurance engagement include the following:

1. A three-party relationship: This involves the practitioner (auditor), the responsible party (management), and the intended users (such as shareholders).
2. Subject matter: The data or information that the practitioner evaluates. In this case, it could be financial statements or compliance reports.
3. Suitable criteria: The rules or standards against which the subject matter is evaluated, such as IFRS or GAAP for financial reporting.
4. Evidence: Information used by the practitioner to support the audit opinion, which must be sufficient and appropriate.
5. Assurance report: The final report containing the practitioner’s opinion based on the evidence gathered, issued to the intended users.

b. Levels of assurance (4 Marks)

1. Reasonable assurance: Provides a high level of assurance, expressed positively, e.g., “In our opinion, the accounts give a true and fair view.” This is the objective of a statutory audit.
2. Limited assurance: Provides a moderate level of assurance, expressed negatively, e.g., “Nothing has come to our attention that causes us to believe the financial statements do not give a true and fair view.” This is often used in review engagements.

c. Categories of threats to professional ethics of an auditor (6 Marks)

1. Self-interest threat: Arises when the auditor has financial or other interests that could unduly influence their judgment.
2. Self-review threat: Occurs when the auditor reviews their own work, which may lead to biased conclusions.
3. Advocacy threat: Happens when the auditor promotes a client’s position, potentially compromising objectivity.
4. Familiarity threat: Arises when the auditor becomes too close to the client, impairing professional skepticism.
5. Intimidation threat: Results from real or perceived pressure from the client that influences the auditor’s objectivity.
6. Management threat: Occurs when the auditor takes on management responsibilities for the client, leading to a conflict of interest.
