[1] At February 28, 2013 and November 30, 2012, we had foreign currency forwards totaling $129 million and $235 million, respectively, that are designated as hedges of our net investments in foreign operations, which have a euro-denominated functional currency. At February 28, 2013, the $129 million of outstanding foreign currency forwards mature through July 2017.

[2] At February 28, 2013 and November 30, 2012, we had foreign currency derivatives consisting of foreign currency zero cost collars that are designated as foreign currency cash flow hedges for a portion of our euro-denominated shipbuilding payments. See "Newbuild Currency Risks" below for additional information regarding these derivatives.

[3] We have euro interest rate swaps designated as cash flow hedges whereby we receive floating interest rate payments in exchange for making fixed interest rate payments. At February 28, 2013 and November 30, 2012, these interest rate swap agreements effectively changed $257 million and $269 million, respectively, of EURIBOR-based floating rate euro debt to fixed rate debt. These interest rate swaps settle through February 2022. In addition, at February 28, 2013, we had U.S. dollar interest rate swaps designated as fair value hedges whereby we receive fixed interest rate payments in exchange for making floating interest rate payments. These interest rate swap agreements effectively changed $500 million of fixed rate debt to U.S. dollar LIBOR-based floating rate debt. These interest rate swaps settle through February 2016.

[4] At February 28, 2013, we had fuel derivatives consisting of zero cost collars on Brent crude oil ("Brent") to cover a portion of our estimated fuel consumption through 2017. See "Fuel Price Risks" below for additional information regarding these fuel derivatives. At November 30, 2012, we had fuel derivatives consisting of zero cost collars on Brent to cover a portion of our estimated fuel consumption through 2016. There were no realized gains or losses recognized in the three months ended February 28/29, 2013 and 2012 on our fuel derivatives.
