5. Fair Value Measurements

     Fair Value of Financial Instruments

     The FASB accounting guidance requires disclosure of fair value information about financial instruments, whether or not recognized in the accompanying condensed, consolidated balance sheets. Fair value as defined by the guidance is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value estimates of financial instruments are not necessarily indicative of the amounts we might pay or receive in actual market transactions. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts.

     Cash and Cash Equivalents. These balances include cash and cash equivalents with maturities of less than three months. The carrying amount approximates fair value due to the short-term maturities of these instruments.

     Receivables, Less Allowance for Doubtful Accounts, Accounts Payable and Certain Other Accrued Liabilities. Due to their short-term nature, fair value approximates carrying value.

     Long-Term Debt. The fair value of debt at June 30, 2011 and December 31, 2010 is based upon the ask price quoted from an external source, which is considered a Level 2 input.

     The following table reflects the carrying value and fair value of our variable-rate long-term debt (in thousands):

	As of June 30, 2011				As of December 31, 2010
	Carrying		Fair		Carrying		Fair
	Value		Value		Value		Value
Variable-rate long-term debt	$	481,250	$	483,055	$	493,750	$	496,219

     At June 30, 2011 and December 31, 2010, we did not have any applicable nonrecurring measurements of nonfinancial assets and nonfinancial liabilities.
