Fair Value Disclosures [Abstract]

FAIR VALUE OF ASSETS AND LIABILITIES

FAIR VALUE OF ASSETS ANDLIABILITIES

The Company measures its financial assets and liabilities using one or more of the following three valuation techniques:

Market approach — Prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities.

Cost approach — Amount that would be required to replace the service capacity of an asset (replacement cost).

Income approach — Techniques to convert future amounts to a single present amount based upon market expectations.

The hierarchy that prioritizes the inputs to valuation techniques used to measure fair value is divided into three levels:

Level 1 — Unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2 — Unadjusted quoted prices in active markets for similar assets or liabilities, unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active or inputs, other than quoted prices in active markets, that are observable either directly or indirectly.

Level 3 — Unobservable inputs for which there is little or no market data.

Summary of Assets and Liabilities Recorded at Fair Market Value

Refer to note 12 for assets held in the Company’s defined pension plans, which are measured at fair value. Assets and liabilities subject to fair value measurement are as follows:

Short-Term Investments The Company has investments in certificates of deposit that are recorded at cost, which approximates fair value. Additionally, the Company has investments in U.S. dollar indexed bond funds that are classified as available-for-sale and stated at fair value. U.S. dollar indexed bond funds are reported at net asset value, which is the practical expedient for fair value as determined by banks where funds are held.

Assets Held in a Rabbi Trust / Deferred Compensation The fair value of the assets held in a rabbi trust (refer to notes 5 and 12) is derived from investments in a mix of money market, fixed income and equity funds managed by Vanguard. The related deferred compensation liability is recorded at fair value.

Foreign Exchange Forward Contracts A substantial portion of the Company’s operations and revenues are international. As a result, changes in foreign exchange rates can create substantial foreign exchange gains and losses from the revaluation of non-functional currency monetary assets and liabilities. The foreign exchange contracts are valued using the market approach based on observable market transactions of forward rates.

Interest Rate Swaps The Company has variable rate debt and is subject to fluctuations in interest related cash flows due to changes in market interest rates. The Company’s policy allows it to periodically enter into derivative instruments designated as cash flow hedges to fix some portion of future variable rate based interest expense. The Company executed two pay-fixed receive-variable interest rate swaps to hedge against changes in the LIBOR benchmark interest rate on a portion of the Company’s LIBOR-based borrowings. The fair value of the swap is determined using the income approach and is calculated based on LIBOR rates at the reporting date.

Summary of Assets and Liabilities Recorded at Carrying Value

The fair value of the Company’s cash and cash equivalents, trade receivables and accounts payable, approximates the carrying value due to the relative short maturity of these instruments. Refer to note 10 related to the Company's investment in a non-consolidated affiliate. The fair value and carrying value of the Company’s debt instruments are summarized as follows:

	December 31, 2012				December 31, 2011
	Fair Value		Carrying Value		Fair Value		Carrying Value
Notes payable	$	34,212	$	34,212	$	21,722	$	21,722
Long-term debt	630,450		617,534		612,551		606,154
Total debt instruments	$	664,662	$	651,746	$	634,273	$	627,876

The fair value of the Company’s industrial development revenue bonds are measured using unadjusted quoted prices in active markets for identical assets categorized as level 1 inputs. The fair value of the Company’s current notes payable and credit facility debt instruments approximates the carrying value due to the relative short maturity of the revolving borrowings under these instruments. The fair values of the Company’s long-term senior notes were estimated using market observable inputs for the Company’s comparable peers with public debt, including quoted prices in active markets, market indices and interest rate measurements, considered level 2 inputs.
