(1)

Money market funds, certificates of deposit and commercial paper with an original maturity of less than ninety days are included within cash and cash equivalents. The remaining balance of cash and cash equivalents as of December 31, 2017, and December 31, 2016, consisted of demand deposits. Commercial paper and certificates of deposit with an original maturity of over ninety days are included within marketable securities.

(2)

Equity mutual funds relate to a deferred compensation plan that was assumed as part of a previous business combination. This amount is included within other long-term assets. See number (4) below for a discussion of the related deferred compensation liability.

(3)

Foreign currency exchange contracts are included within other current assets; other long-term assets; accrued liabilities; or other long-term liabilities depending on the gain (loss) position and anticipated settlement date.

(4)

A deferred compensation plan assumed as part of a previous business combination is included within accrued liabilities and other long-term liabilities. The fair value of our deferred compensation plan is indexed to the performance of the underlying equity mutual funds discussed in number (2) above.
