[1] Cash and cash equivalents are stated at nominal value, which equals fair value.

[2] For investments in auction rate securities, the fair values were based on discounted cash flow valuation models, primarily utilizing unobservable inputs. See Note 6, "Auction Rate Securities," for the roll-forwards of assets measured at fair value using significant unobservable Level 3 inputs and the sensitivity analysis of significant inputs.

[3] Represents outstanding borrowings under our $650.0 million five-year syndicated line of credit. Due to variable interest rates, the carrying value of outstanding borrowings under our line of credit approximates the fair value. See Note 10, "Line of Credit," for more information.
