[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] At May 31, 2014 and November 30, 2013, long-term other assets were substantially all comprised of notes and other receivables. The fair values of our Level 1 and Level 2 notes and other receivables were based on estimated future cash flows discounted at appropriate market interest rates. The fair values of our Level 3 notes receivable were estimated using risk-adjusted discount rates.
[3] 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 May 31, 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 May 31, 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 May 31, 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.
