Fair Value Measurements

4.	FAIR VALUE MEASUREMENTS

A three-tier fair value hierarchy has been established by the Financial Accounting Standards Board ("FASB") to prioritize the inputs used in measuring fair value. These tiers are as follows:

Level 1—Valuations based on quoted prices for identical assets and liabilities in active markets.

Level 2—Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.

Level 3—Valuations based on unobservable inputs reflecting the Company's own assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment.

The fair values of the Company's cash equivalents and marketable securities are based on quoted prices in active markets for identical assets. The fair values of the Company's derivative instruments are determined using pricing models that take into account contract terms and certain observable current market information such as London Inter-Bank Offered Rate ("LIBOR") interest rates.

The following table summarizes the Company's financial assets and liabilities measured at fair value at December 31, 2011:


	Total Fair Value			Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)
Money market account	$	35,129		$	35,129	$	0
U.S. government bond fund		10,013			10,013		0

Total assets	$	45,142		$	45,142	$	0

Interest rate swap	$	(22	)	$	0	$	(22	)

The following table summarizes the Company's financial assets and liabilities measured at fair value at December 31, 2010:


	Total Fair Value			Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)
Money market account	$	5,093		$	5,093	$	0
U.S. government bond fund		20,843			20,843		0

Total assets	$	25,936		$	25,936	$	0

Interest rate swap	$	(44	)	$	0	$	(44	)
