The majority of the Company’s assets and liabilities measured at fair value are based on the market approach valuation technique. With the market approach, fair value is derived using prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities.
The Company’s net commodity derivatives primarily consist of futures or options contracts via regulated exchanges and contracts with producers or customers under which the future settlement date and bushels (or gallons in the case of ethanol contracts) of commodities to be delivered (primarily wheat, corn, soybeans and ethanol) are fixed and under which the price may or may not be fixed. Depending on the specifics of the individual contracts, the fair value is derived from the futures or options prices on the Chicago Mercantile Exchange (“CME”) or the New York Mercantile Exchange (“NYMEX”) for similar commodities and delivery dates as well as observable quotes for local basis adjustments (the difference, which is attributable to local market conditions, between the quoted futures price and the local cash price). Although nonperformance risk, both of the Company and the counterparty, is present in each of these commodity contracts and is a component of the estimated fair values, based on the Company’s historical experience with its producers and customers and the Company’s knowledge of their businesses, the Company does not view nonperformance risk to be a significant input to fair value for the majority of these commodity contracts. However, in situations where the Company believes that nonperformance risk exists, based on past or present experience with a customer or knowledge of the customer’s operations or financial condition, the Company classifies these commodity contracts as “level 3” in the fair value hierarchy and, accordingly, records estimated fair value adjustments based on internal projections and views of these contracts.
During the second quarter of 2010, the Company invested in cumulative convertible preferred shares of Iowa Northern Railway Corporation. These shares are carried at estimated fair value in “Other noncurrent assets” on the Company’s balance sheet. Changes in estimated fair value are recorded within “other comprehensive income”. See Note 8 for further information.
Fair Value of Financial Instruments
The fair value of the Company’s long-term debt is estimated using quoted market prices or discounted future cash flows based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements.
                 
(in thousands)   June 30, 2011   December 31, 2010
     
Fair value of long-term debt and interest rate contracts
  $ 311,886     $ 307,865
Fair value in excess of carrying value
    3,926       4,359
The fair value of the Company’s cash equivalents, accounts receivable and accounts payable approximate their carrying value as they are close to maturity.
