Interest Rate Foreign Currency Swaps We had combined interest rate foreign currency swap agreements for Euro-denominated debt, which hedge our risk to both interest rate and currency movements. In November 2006, we repaid the notional amount of our foreign currency swap of $636. Upon repayment we unwound our swap asset of $284. Additionally, we repaid the collateral associated with the swap contract of $150, which was received by us over the term of the swap agreement.
