[1] Cash equivalents are comprised of highly liquid investments purchased with a maturity of three months or less. The carrying value of these cash equivalents approximates fair value due to their short-term maturities.

[2] The fair value of interest rate swaps, foreign currency contracts and commodity contracts is determined based on the present value of expected future cash flows considering the risks involved, including non-performance risk, and using discount rates appropriate for the respective maturities. Observable Level 2 inputs are used to determine the present value of expected future cash flows. The fair value of these derivative contracts, which are subject to master netting arrangements under certain circumstances, is presented on a gross basis in the condensed consolidated balance sheets.

[3] The other investments balance includes investments in mutual funds, which are used to offset fluctuations in deferred compensation liabilities. These mutual funds primarily invest in the equity securities of companies with large market capitalization and high quality fixed income debt securities. The fair value of these investments is determined using quoted market prices.
