[1] Cash equivalents are comprised of money market funds.

[2] The majority of restricted cash is comprised of money market funds.

[3] At November 30, 2015 and 2014, marketable securities held in rabbi trusts were comprised of Level 1 bonds, frequently-priced mutual funds invested in common stocks, and money market funds and Level 2 other investments. Their use is restricted to funding certain deferred compensation and non-qualified U.S. pension plans.

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

[5] Long-term other asset is 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 2015, 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.
