15. FAIR VALUE OF FINANCIAL INSTRUMENTS

        Financial instruments consist primarily of cash and cash equivalents, accounts receivable, accounts payable, accrued expenses, long-term debt, and commodity forward purchase contracts. The carrying amount of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate their fair value because of the nature of such instruments. The fair values of our 9.0 percent senior secured notes and our natural gas forward purchase contracts are based on quoted market values. Due to limited trading activity for our 7.125 percent senior notes due 2013, our 9.5 percent senior notes due 2014, and our 10.75 percent senior subordinated notes due 2016, the fair values of those notes are estimated based on a weighted average of trading activity before and after the applicable reporting period date. Our ABL Revolver is fair valued using comparable recent third party transactions. Our natural gas forward purchase contracts are fair valued with Level 2 inputs.

        The FASB ASC 820-10 establishes a fair value hierarchy that prioritizes observable and unobservable inputs to valuation techniques used to measure fair value. These levels, in order of highest to lowest priority are described below:

  •         Level 1—Quoted prices (unadjusted) in active markets for identical assets or liabilities at the measurement date.

            Level 2—Observable prices that are based on inputs not quoted on active markets, but corroborated by market data.

            Level 3—Prices that are unobservable for the asset or liability and are developed based on the best information available in the circumstances, which might include the company's own data.
