Fundamental Ethical Principles

Learning outcomes

  • Define the five ACCA/IESBA Fundamental Ethical Principles.

The Five Fundamental Principles

All ACCA members must comply with the IESBA Code of Ethics. The five principles are:

  1. Integrity: Be straightforward and honest in all professional relationships.
  2. Objectivity: Do not allow bias, conflict of interest, or undue influence of others to override professional judgments.
  3. Professional Competence and Due Care: Maintain professional knowledge and act diligently according to technical standards.
  4. Confidentiality: Respect the confidentiality of information acquired; do not disclose it without proper authority.
  5. Professional Behaviour: Comply with relevant laws and avoid any action that discredits the profession.
Practice Question

An accountant is asked to prepare a tax return for a complex international merger, but they have no training in international tax law. If they accept the job, which principle are they violating?

Common Mistake

Confidentiality Exceptions

Confidentiality is not absolute. You MUST break confidentiality if required by law (e.g., reporting money laundering). You MAY break it if you have the client's permission, or if there is a professional right/duty to disclose (e.g., defending yourself in a disciplinary hearing).

Integrity vs Objectivity

Integrity is about telling the truth. If a client asks you to hide a loss, and you do it, you lack integrity. Objectivity is about independence of mind. If you audit a company owned by your brother, you might be honest, but you lack objectivity because of the family tie.

Practice Question

An auditor discovers that the CEO of the company they are auditing is their spouse. The auditor decides to continue the audit anyway. Which principle is most directly threatened?

Examiner Tip

Exam Focus

Memorize the exact names of the 5 principles. Examiners will try to trick you with fake principles like 'Transparency' or 'Independence'. While good concepts, they are NOT the official 5 principles.
