-The statutory auditor has an obligation to refuse the conduct of a statutory audit, if between the statutory auditor or the auditing firm to which he/she belongs and the audited entity there is any financial, professional or other service, which could lead an informed, objective and reasonable third party to conclude that the independence of the auditor or audit firm is at stake. A relationship that could be thought to endanger professional independence is the provision of supplementary non-audit services.-No prohibition regarding the association of accountants with other professionals.
