13. Financial risk management
Through the normal course of business, the Corporation has exposure to market risk (natural gas price risk, interest rate risk, and foreign currency risk), liquidity risk, and credit risk related to its financial and derivative instruments. The Board of Directors, through the Audit and Finance Committee, has the overall responsibility for the establishment and oversight of the Corporation's risk management efforts. The Corporation’s risk management policies and strategies, approved by the Board of Directors and reviewed regularly by the Audit and Finance Committee, provide the framework within which the Corporation may use financial and derivative instruments to manage its risks. The Corporation’s significant risk management policies include the Corporate Derivatives Policy, the Commodity Risk Management Policy, the Corporate Debt and Interest Rate Risk Management Policy, the Foreign Currency Risk Management Policy and the Corporate Credit Risk Management Policy. The objectives, policies, and processes for managing risk were consistent with the prior period.
