[1] Cash and cash equivalents are comprised of cash on hand, and at November 30, 2013, also include time deposits and, due to their short maturities, the carrying values approximate their fair values.

[2] The net difference between the fair value of our fixed rate debt and its carrying value was due to the market interest rates in existence at February 28, 2014 and November 30, 2013 being lower than the fixed interest rates on these debt obligations, including the impact of any changes in our credit ratings. At February 28, 2014 and November 30, 2013, the net difference between the fair value of our floating rate debt and its carrying value was due to the market interest rates in existence at February 28, 2014 and November 30, 2013, being higher and slightly lower, respectively, than the floating interest rates on these debt obligations, including the impact of any changes in our credit ratings. The fair values of our publicly-traded notes were based on their unadjusted quoted market prices in markets that are not sufficiently active to be Level 1. The fair values of our other debt were estimated based on appropriate market interest rates being applied to this debt.
