Fair Value Measurements

9 Months Ended

Sep. 30, 2013

We use a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy, which gives the highest priority to quoted prices in active markets, is comprised of the following three levels:

Level 1 – Unadjusted quoted market prices in active markets for identical assets and liabilities.

Level 2 – Observable inputs, other than Level 1 inputs. Level 2 inputs would typically include quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly.

Level 3 – Prices or valuations that require inputs that are both significant to the measurement and unobservable.

The following tables provide the assets and liabilities carried at fair value measured on a recurring basis as of September 30, 2013 and December 31, 2012 (in thousands):

_________


(1)	Cash and cash equivalents consist primarily of money market funds with original maturity dates of three months or less, which are Level 1 assets. At September 30, 2013 and December 31, 2012, we had $147.2 million and $407.4 million, respectively, in money market funds.


(2)	Restricted cash and short-term investments with original maturities greater than three months are classified as “Prepaid expenses and other” on our Condensed Consolidated Balance Sheets.

We believe that the carrying values of our financial instruments, which include accounts receivable and other financing commitments, approximate their fair values due primarily to their short-term maturities and low risk of counterparty default. The carrying value of our 2011 Revolving Credit Facility approximates the fair value due to the variable rate on such debt.
