Fair Value Measurements

Note 6.  Fair Value Measurements

FASB accounting standards provide a comprehensive framework for measuring fair value and sets forth a definition of fair value and establishes a hierarchy prioritizing the inputs to valuation techniques, giving the highest priority to quoted prices in active markets for identical assets and liabilities and the lowest priority to unobservable value inputs.  Levels within the hierarchy are defined as follows:

· Level 1—Unadjusted quoted prices for identical assets and liabilities in active markets;

· Level 2—Quoted prices for similar assets and liabilities in active markets (other than those included in Level 1) which are observable for the asset or liability, either directly or indirectly; and

· Level 3—Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

The following table sets forth financial assets and liabilities measured at fair value in the consolidated balance sheets and the respective levels to which the fair value measurements are classified within the fair value hierarchy as of June 30, 2011, and December 31, 2010 (in thousands):

	Total		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
June 30, 2011
Commodity futures — financial assets	$	3,343	$	—	$	3,343	$	—
Commodity futures — financial liabilities	3,653		—		3,653		—
December 31, 2010
Commodity futures — financial assets	7,052		—		7,052		—
Commodity futures — financial liabilities	12,040		—		12,040		—

The carrying amounts of financial instruments including cash and equivalents, accounts receivable and accounts payable approximate fair value, because of the relatively short maturity of these instruments. The fair values of commodity futures contracts are estimated by the use of quoted market prices, estimates obtained from brokers, and other appropriate valuation techniques based on references available. The fair value of long-term debt, including current maturities, was approximately $2.5 billion (with a corresponding carrying amount in the consolidated balance sheet of $2.4 billion) at June 30, 2011, and December 31, 2010, and was based on quoted market prices.
