Cash Flow Hedges
In the third quarter of 2008, we entered into interest rate swap agreements that effectively converted $200 million of our Credit Facilities, which is floating rate debt, to a fixed rate basis through August 2011, thus reducing the impact of interest rate changes on future interest expense.
All derivative contracts used to manage interest rate risk are measured at fair value and reported in other current assets or other accrued liabilities as appropriate with the offset in accumulated other comprehensive income (loss) within NASDAQ OMX stockholders equity in the Condensed Consolidated Balance Sheets. Any ineffectiveness would impact earnings through interest expense. There was no material ineffectiveness recorded in earnings for the three months ended March 31, 2009.
