Net Investment Hedges
The net assets of our foreign subsidiaries are exposed to volatility in foreign currency exchange rates. We may utilize net investment hedges to offset the translation adjustment arising from remeasuring our investment in foreign subsidiaries. We have designated our NOK-denominated debt that was assumed in the Nord Pool transaction as a net investment hedge. As a result, any foreign currency gains and losses resulting from this NOK-denominated debt is accounted for as a component of accumulated other comprehensive income (loss) within NASDAQ OMX stockholders equity in the Condensed Consolidated Balance Sheets. For the three months ended March 31, 2009, a loss of $6 million is included in the change in the foreign currency translation adjustment component of accumulated other comprehensive loss within NASDAQ OMX stockholders equity in the Condensed Consolidated Balance Sheets.
