The Company is subject to the risk of increased costs arising from adverse changes in certain commodity prices. In the normal course of business, the Company manages these risks through a variety of strategies, including the use of derivative instruments. The Company does not use derivative instruments for trading or speculative purposes. All derivative instruments are recorded at fair value as either assets or liabilities in the Company’s condensed consolidated balance sheets. These derivative instruments are not designated

as hedging instruments under GAAP and are used as “economic hedges” to manage certain commodity price risk. Derivative instruments held are marked to market on a monthly basis and recognized in earnings consistent with the expense classification of the underlying hedged item. Settlements of derivative agreements are included in cash flows from operating activities on the Company’s condensed consolidated statements of cash flows.

The Company uses several different financial institutions for commodity derivative instruments to minimize the concentration of credit risk. While the Company would be exposed to credit loss in the event of nonperformance by these counterparties, the Company does not anticipate nonperformance by these parties.
