[1] At November 30, 2014 and 2013, we had foreign currency forwards totaling $403 million and $578 million, respectively, that are designated as hedges of our net investments in foreign operations, which have a euro-denominated functional currency. At November 30, 2014, these foreign currency forwards settle through July 2017.

[2] At November 30, 2014 and 2013, 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 November 30, 2014 and 2013, these interest rate swap agreements effectively changed $750 million and $909 million, respectively, of EURIBOR-based floating rate euro debt to fixed rate euro debt. These interest rate swaps settle through March 2025. In addition, at November 30, 2014 and 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. At November 30, 2014 and 2013, 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 November 30, 2014 and 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 2018 and through 2017, respectively. See “Fuel Price Risks” below for additional information regarding these fuel derivatives.
