Internal audit’s role in good governance
Internal control is an important cornerstone for banks’ long-term sound governance. It should be tailored to the business model, risks and organisational structure. As the third line of defence, reporting to CEOs and the board, internal audit gives an overall assurance on internal control effectiveness including an independent review of risk and control functions as well as insights on efficiency.
The audit departments of banking groups need to deliver consistent and adequate levels of assurance across the group, while considering both group and subsidiary regulatory requirements, with the intention of fostering consolidated supervision across the group.
Internal audit function has an important role to play in providing assurance over the effectiveness and security of key processes outsourced from banks to third parties. It is crucial that key stakeholders, including management, the board and the bank’s supervisors can place reliance on the work of internal audit in respect of the risk management of third parties, while at the same time maintaining a reasonable expectation of the extent of the internal audit function’s responsibilities in this area.
An audit report generally includes the management action defined as a response to the recommendation, together with a due date and an action owner. Every internal audit function should have a process for monitoring follow-up on implementation of management actions. This can be an indicator for the internal audit function’s effectiveness.
To manage risks effectively is an essential part of good corporate governance. An important role of each organisation is to identify all business risks and uncertainties which the organisation faces, quickly implementing risk mitigating measures and enhancing the system of internal controls. The Chief Audit Executive must establish a risk-based plan to determine the priorities of the internal audit activity, consistent with the organisation’s goals – an approach that can be difficult to combine with traditional, cyclical auditing methods. The paper outlines strategies to combine a traditional cyclical approach to internal auditing with a risk-based approach.
