Board composition and operational risk events of financial institutions

We investigate the relation between board composition and operational risk events of financial institutions in the period from 1996 to 2010. Drawing from corporate governance literature, we consider the impact of board characteristics on the likelihood of operational risk events. Overall, our findings suggest that board size is negatively and non-linearly associated with the possibility of operational risk events. For the event types of ‘‘Clients, Products, and Business Practices,’’ and ‘‘Internal Fraud and External Fraud,’’ firms with a higher proportion of independent directors are less likely to suffer from fraud or failure to complywith professional obligations to clients. Our results on age and tenure heterogeneity also indicate that having amore diverse board can have an adverse impact on the board monitoring function. These results can shed new light on board demographics and operational risk management in financial institutions. 2013 Elsevier B.V. All rights reserved.
