We are exposed to various types of market risk in the normal course of business, including the impact of interest rate changes, foreign currency exchange rate fluctuations, changes in equity investment prices and changes in corporate tax rates. We employ risk management strategies using a variety of derivatives, including interest rate swap agreements, interest rate locks, foreign currency forwards, equity options and basis swap agreements. We do not hold derivatives for trading purposes.

It is our general policy to enter into interest rate, foreign currency and other derivative transactions only to the extent necessary to achieve our desired objectives in limiting our exposures to the various market risks. Our objectives include maintaining a mix of fixed and variable rate debt to lower borrowing costs within reasonable risk parameters and to protect against earnings and cash flow volatility resulting from changes in market conditions. We do not hedge our market risk exposure in a manner that would completely eliminate the effect of changes in interest rates, equity prices and foreign exchange rates on our earnings. We do not expect that our net income, liquidity and cash flows will be materially affected by these risk management strategies.

The table that follows summarizes the fair values of our long-term debt and interest rate derivatives as of December 31, 2004 and 2003. The table also provides a sensitivity analysis of the estimated fair values of these financial instruments assuming 100-basis-point upward and downward parallel shifts in the yield curve. Our sensitivity analysis did not include the fair values of our commercial paper and bank loans because they are not significantly affected by changes in market interest rates.

The functional currency for all of our foreign operations is the local currency. The translation of income statement and balance sheet amounts of these entities into U.S. dollars are recorded as cumulative translation adjustments, which are included in Accumulated Other Comprehensive Loss in our consolidated balance sheets. At December 31, 2004, our primary translation exposure was to the Venezuelan bolivar, Dominican Republic peso and the euro.

During 2004, we entered into foreign currency forward contracts to hedge our net investment in our Canadian operations and investments. In accordance with the provisions of SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities” and related amendments and interpretations, changes in the fair value of these contracts due to exchange rate fluctuations were recognized in Accumulated Other Comprehensive Loss and offset the impact of foreign currency changes on the value of our net investment in the operations being hedged. During the fourth quarter of 2004, we sold our Canadian operations and investments. Accordingly, the unrealized losses on these net investment hedge contracts were realized in net income along with the corresponding foreign currency translation balance. We recorded realized losses of $106 million ($58 million after-tax) related to these hedge contracts. We have not hedged our accounting translation exposure to foreign currency fluctuations relative to the carrying value of our other investments.

Through June 30, 2003, and during 2002, our earnings were affected by foreign currency gains or losses associated with the unhedged portion of U. S. dollar denominated debt at Iusacell (see “Consolidated Results of Operations – Other Consolidated Results – Discontinued Operations”).
