Since the Asian financial crisis in 1997, there has been renewed interest in corporate governance policies and practices. This study focuses on corporate governance practices in Malaysia, where the increasing incidence of fraud suggests a lack of adequate corporate governance systems in Malaysian listed companies. Using an unbalanced data set comprising 200 companies representing a total of 579 firm-year observations, this study examines the effects of internal corporate governance mechanisms on the occurrence of fraud. Specifically, it looks at the effects of board characteristics, ownership structure and quality of audit on the occurrence of fraud in Malaysian listed companies from 2007 to 2009. The findings indicate that the number of board meetings was positively associated with the occurrence of fraud, but both state and foreign ownership revealed a negative correlation, whereas factors including the number of independent directors, board size, CEO duality and the quality of audit had no observable effects.
