7. Fair Value of Financial Assets and Liabilities

In determining fair value, the company uses various valuation approaches within the fair value measurement framework.  Fair value measurements are determined based on the assumptions that market participants would use in pricing an asset or liability. Applicable accounting literature establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available.  Applicable accounting literature defines levels within the hierarchy based on the reliability of inputs as follows:

Level 1—Valuations based on unadjusted quoted prices for identical assets or liabilities in active markets;

Level 2—Valuations based on quoted prices for similar assets or liabilities or identical assets or liabilities in less active markets, such as dealer or broker markets; and

Level 3—Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable, such as pricing models, discounted cash flow models and similar techniques not based on market, exchange, dealer or broker-traded transactions.

Following is a description of the valuation methodologies used for instruments measured at fair value and their classification in the valuation hierarchy.

Available-for-sale securities

Equity securities listed on a national market or exchange are valued at the last sales price and comprise the Company’s investment in Polytronics. Such securities are classified within Level 1 of the valuation hierarchy.

Derivative instruments

The fair value of commodity derivatives are valued based on quoted futures prices for the underlying commodity and are categorized as Level 2. The fair values of foreign exchange rate derivatives are determined based on inputs that are readily available in public markets or can be derived from information available in publicly quoted markets and are categorized as Level 2.

The company does not have any financial assets or liabilities measured at fair value on a recurring basis categorized as Level 3, and there were no transfers in or out of Level 2 or Level 3 during the six months ended June 30, 2012. There were no changes during the six months ended June 30, 2012, to the company’s valuation techniques used to measure asset and liability fair values on a recurring basis. As of June 30, 2012, the company held no non-financial assets or liabilities that are required to be measured at fair value on a recurring basis.

The following table presents assets measured at fair value by classification within the fair value hierarchy as of June 30, 2012 (in thousands):

The company’s other financial instruments include cash and cash equivalents, accounts receivable, accounts payable, current portion of long-term debt, and long-term debt. Due to their short-term maturity, the carrying amounts of cash and cash equivalents, accounts receivable, accounts payable, and current portion of long-term debt approximate their fair values. The company’s long-term debt fair value approximates book value at June 30, 2012 and December 31, 2011, respectively, as the long-term debt variable interest rates fluctuate along with market interest rates.
