Internal Audit Charter

The Internal Audit Charter and the implementation of its tasks refer to standards and guidances issued by the Institute of Internal Auditors and SIG’s Internal Audit. Internal Audit activities were performed based on the risk-based internal audit plan, approved by the President Director with the oversight of the Audit Committee.

The Internal Audit Unit has held the Internal Audit Charter since 5 February 2015, which was updated and approved by the President Director, Chairman of the Audit Committee and the President Commissioner of the Company on 28 October 2019. The Internal Audit Charter is the Internal Audit guideline for carrying out its duties and responsibilities in a competent, independent, and accountable manner, so that it can be accepted by all interested parties.
