This section of the IESBA Code of Ethics discusses threats to independence for professional accountants providing assurance services. It states that assuming management responsibilities or preparing subject matter information creates self-review threats. Contingent fees for assurance engagements also create unacceptable self-interest threats. However, for nonassurance services, contingent fees or unpaid fees may create threats depending on factors like fee amounts and authority over outcomes. Threats must be evaluated and safeguards applied to maintain independence.
