Our market risk includes the potential loss arising from adverse changes in foreign currency exchange rates, interest rates and commodity prices, and the credit risk of our customers and third-party depository institutions that hold our cash and short term deposits. From time to time, we use derivative financial instruments, principally foreign currency swaps, forward foreign currency contracts, interest rate caps (options), and interest rate swaps to reduce our exposure to foreign currency risk and interest rate risk. We do not hold or issue derivatives for speculative purposes and monitor closely the credit quality of the institutions with which we transact. Our objective in managing these risks is to reduce fluctuations in earnings and cash flows associated with changes in foreign currency exchange rates and interest rate movements. For a discussion of quantitative and qualitative disclosures about market risk, please refer to our annual report from which our exposure to market risk has not materially changed.
