The FASB's guidance regarding fair value measurements establishes a common definition for fair value to be applied to guidance requiring use of fair value, establishes a framework for measuring fair value, and expands disclosure about such fair value measurements. The guidance does not require any new fair value measurements, but rather applies to all other accounting guidance that requires or permits fair value measurements.

The guidance utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels:

The Company values its interest rate swaps, company-owned life insurance policies, various deferred compensation assets and liabilities, acquisition-related consideration and an obligation related to a non-competition agreement at fair value. The Company's assets and liabilities subject to fair value measurement are as follows (in thousands):

The fair values of Company-owned life insurance (“COLI”) and COLI deferred compensation assets are based on quotes for like instruments with similar credit ratings and terms. The fair values of other deferred compensation assets and liabilities are based on quoted prices in active markets. The fair values of interest rate derivatives are based on quoted market prices from various banks for similar instruments. The fair value of the earnout is based on unobservable inputs and is classified as Level 3. Significant inputs and assumptions are management's estimate of the probability of the earnout ultimately being met/paid and the discount rate used to present value the liability. The fair values of holdbacks and the obligation related to a non-competition agreement are also based on unobservable inputs and are classified as Level 3. Significant inputs and assumptions for both the obligation related to the non-competition agreement and the holdbacks are management's estimate of the discount rate used to present value the liabilities.

Changes in the fair value of the Level 3 liabilities during the year ended December 31, 2011 were as follows:

						Non-competition
		Earnout		Hold-back		Agreement			Hold-back
		Summit		Tecniquimia		Obligation			GW Smith	Total
Balance at December 31, 2010		$	5,350	$	0	$	0	$	0	$	5,350
