ICAEW defined external assurance as the provision of an independent opinion by an expert (chartered accountants) on information prepared by one party for the benefit of another parties. By providing assurance on non-financial information reporting is also known as external assurance reports. Basically there is no requirement or significant demand by public or association on this external assurance. Therefore, auditors are only required to meet their responsibilities in checking the consistency and reliability of information in the reports to enhance corporate governance. In future, if there are major errors from external assurance reports which affect the perceptions of investor, this would lead to an increase in demand for external assurance and indirectly will cause strictly rules or framework to be implemented on this practices. If stakeholders were lose confidence in the quality of information, the use and value of external assurance reports might change according to that.
