Auditor independence: prohibition on specified non audit services unless approved by board or audit committee, preserving audit objectivity. An auditor may only provide other services approved by the Board or the audit committee and must not perform specified non audit services-such as accounting and bookkeeping, internal audit, financial information system design, actuarial, investment advisory and banking, outsourced financial services, and management services-directly or indirectly to the company or its holding or subsidiary companies. 'Directly or indirectly' includes services via relatives, connected persons, entities using the auditor's name or entities in which the auditor or firm has significant influence or control. Pre existing non audit engagements must be regularised by the end of the first post commencement financial year.
