Independent assurance and reviews

Confident decision-making fuelled by reliable information and processes

Reliable and credible information is high on stakeholders’ agendas, particularly in today’s world where data is widely available. Independent assurance provides confidence in the subject matter of that assurance engagement.
In addition to statutory audits, we perform a wide range of assurance engagements to help you meet regulatory requirements, ensure transparency and enhance stakeholder engagement.

Our approach

We perform independent assurance engagements which offer expert opinions on different areas of business performance and information. These opinions meet the requirements of international professional standards and enhance credibility and respond to the needs of stakeholders for greater transparency.

  • Assurance works;  
  • Internal controls, as NBC-TO 3402 (ISAE3402);
