In Control Statement

Our Board of Directors is responsible for the oversight of our risk management activities and has specifically designated the audit and compliance committee to assist our Board of Directors in this task and prepare recommendations in this respect to the Board of Directors. While our Board of Directors oversees our risk management, our senior management is responsible for day-to-day risk management processes. Our Board of Directors expects our senior management to consider risk and risk management in each business decision, to proactively develop and monitor risk management strategies and processes for day-to-day activities and to effectively implement risk management strategies adopted by the Board of Directors. We believe this division of responsibilities is the most effective approach for addressing the risks we face.
