We are exposed to various market risks arising from our normal business activities. These market risks, which are beyond our control, primarily involve the possibility that changes in interest rates, inflation, exchange rates and commodity prices will adversely affect the value of our financial assets and liabilities or future cash flows and earnings. Our risk management strategy is designed to mitigate the financial impact derived from our exposure to market risks, and accordingly, we have used and may continue to use interest rate, exchange rates and commodity derivative instruments, cash and receivables to mitigate these market risks. Our hedging activities are governed by a financial risk management department, which follows corporate governance standards and guidelines for our company that are established by our risk management committee and approved by our board of directors. 86 Table of Contents For more information about our risk management, see note 25 to our unaudited interim financial statements, which are included in Part I, Item I of this Quarterly Report, and note 27 to our audited financial statements, which are included in our Form 20-F.
