At November 30, 2013, marketable securities held in rabbi trusts were principally comprised of Level 1 frequently-priced mutual funds invested in common stocks and Level 2 other investments.

[4] See “Derivative Instruments and Hedging Activities” section below for detailed information regarding our derivative financial instruments.

[5] Long-term other assets are comprised of an auction-rate security. The fair value was based on a broker quote in an inactive market, which is considered a Level 3 input. During the three months ended February 28, 2014, there were no purchases or sales pertaining to this auction-rate security and, accordingly, the change in its fair value was based solely on the strengthening of the underlying credit.
