8.4 Supervisory and control instruments in relation to the external audit

The Audit Committee reviews the multi-year audit planning as well as the planned annual auditing activities and, in a specific agenda item, discusses these with the Auditor-in-Charge from the external auditing firm as well as the Head of Group Internal Audit. The Audit Committee attaches ­particular importance to a risk-oriented approach in the planning and conduct of the audit, as well as appropriate coordination of the auditing activities of the external auditors with those of Internal Audit.

All reports from the external auditors are reviewed at the meetings of the Audit Committee. In 2020, the external auditors were present at all meetings of the Audit Com­mittee in which external audit-related items were on the agenda. In addition, the Auditor-in-Charge was in attendance at the Board of Director’s meeting to present and deal with the Auditor’s Report prescribed under the Banking Act.

Each year, the Audit Committee assesses and evaluates the effectiveness and independence of the external auditors.During this process, it relies on documents generated by the external auditors, such as the Auditors’ Report prescribed under the Banking Act, management letters, as well as oral and written statements of position on individual issues and technical questions in connection with financial-statement reporting and the audit. Furthermore, a systematic annual assessment is made on the basis of checklists and fee ­comparisons within the auditing segment. Based on this evaluation, a motion is submitted to the Board of Directors for the attention of the Annual General Meeting as regards the election of the external auditors and Group auditors.
