Fair value is determined using a hierarchy that has three levels based on the reliability of the inputs used to determine fair value. Level 1 refers to fair values determined based on quoted prices in active markets for identical assets. Level 2 refers to fair values estimated using significant other observable inputs, and Level 3 includes fair values estimated using significant unobservable inputs. The following table presents the Company's assets and liabilities that are measured at fair value on a recurring basis (in thousands):


	September 30, 2011								September 30, 2010
	Total		Level 1		Level 2		Level 3		Total		Level 1		Level 2		Level 3

Money market funds, U.S. Treasury Bills and derivative instruments are valued using a market approach based on the quoted market prices of identical instruments. Contingent consideration liabilities are valued using Level 3 inputs. For further information on the inputs used in determining the fair value, and a roll-forward of the contingent consideration liability, see Note 10 of the Notes to Condensed Consolidated Financial Statements.

The carrying values of cash and cash equivalents, short-term investments, accounts receivable and accounts payable approximated their fair value due to the short-term nature of these instruments.

In September 2011, the Company entered into a derivative instrument for 3 million pounds of aluminum to manage a portion of the exposure to movements associated with aluminum costs in 2012, representing approximately 10 percent of the Company's anticipated aluminum purchases in 2012. While this derivative instrument is considered to be an economic hedge of the underlying movement in the price of aluminum, it is not designated or accounted for as a hedge. The change in fair value of this instrument is "marked to market" at the end of each reporting period and the gain or loss is recorded in cost of goods sold in the Condensed Consolidated Statements of Income, with the corresponding amount recorded in the Condensed Consolidated Balance Sheet.

Certain assets and liabilities have been measured at fair value on a non-recurring basis using significant unobservable inputs (Level 3). The following table presents the non-recurring losses recognized using fair value measurements and the carrying value of any assets and liabilities which were measured using fair value estimates during the nine months ended (in thousands):


	September 30, 2011				September 30, 2010
	Carrying Value		Non-recurring losses		Carrying Value		Non-recurring losses
Assets
Vacant owned facilities	$	10,123	$	-	$	11,662	$	-
Net assets of acquired
businesses		37,340		-		24,647		-
Total assets	$	47,463	$	-	$	36,309	$	-

Liabilities
Vacant leased facilities	$	583	$	203	$	932	$	308
Total liabilities	$	583	$	203	$	932	$	308

At September 30, 2011, the Company owned six facilities which it is attempting to sell. In addition to the owned facilities which the Company is attempting to sell, the Company is attempting to sublease four vacant facilities which it leases. The determination of fair value is based on the best information available, using Level 3 inputs, including internal cash flow estimates discounted at an appropriate interest rate, market prices for similar assets, broker quotes and independent appraisals, as appropriate.

Assets acquired and liabilities assumed in a business combination were recorded at fair value as of the acquisition date. Depending upon the type of asset acquired, the Company used different valuation techniques in determining the fair value of each asset. Those techniques included comparable market prices, long-term sales, profitability and cash flow forecasts, assumptions regarding future industry-specific economic and market conditions, weighted average cost of capital, as well as other techniques as circumstances required. For further information on acquired assets, see Note 3 of the Notes to Condensed Consolidated Financial Statements.
