They are market risk, credit risk, liquidity risk, and operational risk. Compared to the first three types of risk, operational risk, defined as the risk of loss resulting from the inadequate or failed internal processes, people, and systems or from external events, is less studied in the academic literature. However, operational risk is as important as and has no less economic impact than other risks a firm may encounter. In recent years, the issue of operational risk has drawn more attention due to Basel II. Corporate governance is one of the major research fields in finance in recent years. It affects a firm in various aspects, including investment decisions, financing decisions, and payout policies. Corporate governance is also related to operational risk management. Modern internal auditors provide assurance regarding the firm’s corporate governance, internal control systems, and risk management processes. Therefore, better corporate governance would help reducing operational risk. The passage of Sarbanes-Oxley Act (SOX) in 2002 may further strengthen the influence of corporate governance on operational risk control. The research project thus seeks to contribute the related literature and to fill important academic gaps in a novel research field. We try to thoroughly study the operational loss events from three different aspects: (i) the determinants of operational loss events, (ii) change in corporate governance mechanism following operational loss events, and (iii) the impact of SOX on operational risk management. With the passage of SOX and the introduction of Basel II, the research project provides not only academic contributions but also useful implications regarding operational risk management for the practitioners. We believe it is a research project with high potential to publish articles in high quality international journals.
