The Board of Commissioners exercises authority in appointing an Audit Committee member to assist its supervisory duties and functions. This authority stems from Financial Services Authority (OJK) Regulation No.55/POJK.04/2015 dated 29 December 2015 concerning the Establishment of an Audit Committee and Guidelines on Committee Duties (POJK 55/2015), and IDX Regulation No. I-A, as an appendix to IDX Board of Directors Decree No. Kep-00001/BEI/01-201 regarding Registration of Shares and Equity Securities outside Shares Issued by the Listed Company, which has been terminated as of 27 December 2018 and replaced with IDX Regulation No. I-A Appendix to IDX Board of Directors Decision No. Kep-00183/BEI/12-2018 dated 27 December 2018 (IDX Regulation No. I-A 2018). The Audit Committee takes responsibility in establishing appropriate internal controls, improving the quality of transparency and financial reports, as well as assessing scope, accuracy, independency and objectivity to the external audit.
