(1) When carrying out a statutory audit, the statutory auditor or the audit firm shall -
(a) maintain professional scepticism throughout the audit,
(b) maintain professional scepticism when reviewing management estimates relating to fair values, the impairment of assets, provisions, and future cash flow relevant to the audited entity's ability to continue as a going concern, and
(c) recognise the possibility of a material misstatement due to facts or behaviour indicating irregularities, including fraud or error, notwithstanding the statutory auditor's or the audit firm's past experience of the honesty and integrity of the audited entity's management and of the persons charged with its governance.
(2) For the purposes of this Regulation, "professional scepticism" means an attitude that includes a questioning mind, being alert to conditions which may indicate possible misstatement due to error or fraud, and a critical assessment of audit evidence.
