Fair Value of Financial Instruments

Note 11—Fair Value of Financial Instruments

        Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A three level hierarchy has been established for valuing assets and liabilities based on how transparent (observable) the inputs are that are used to determine fair value, with the inputs considered most observable categorized as Level 1 and those that are the least observable categorized as Level 3. Hierarchy levels are defined as follows:

Level 1:	Quoted prices in active markets for identical assets and liabilities;
Level 2:	Quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar instruments in markets that are not active; and
Level 3:	Unobservable inputs that are supported by little or no market data which require the reporting entity to develop its own assumptions.

        The following table presents information about the Company's assets and liabilities that are measured at fair value on a recurring basis as of March 31, 2012 and December 31, 2011 and indicate the fair value hierarchy of the valuation techniques utilized to determine such values. For some assets, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. When this is the case, the asset is categorized based on the level of the most significant input to the fair value measurement. The Company's assessment of the significance of a particular input to the fair value measurement requires judgment and considers factors specific to the assets being valued.

        Below is a summary of the Company's valuation techniques for Level 1 and Level 2 financial assets and liabilities:

        Equity securities—As of March 31, 2012 the Company held equity investments in other current assets classified as trading. Changes in the fair value of trading securities are recorded in other income (loss) and determined using observable market prices. For the three months ended March 31, 2012 a loss of $6.5 million was recorded related to trading securities held at the reporting date. Realized losses of $452,000 on the sale of available-for-sale securities were recorded in other income (loss) during the three months ended March 31, 2012 and determined using the specific identification method.

        Interest rate cap—The fair value of the interest rate cap was determined using quoted dealer prices for similar contracts in active over-the-counter markets.

        Natural gas hedge—The fair value of the natural gas hedge was determined using quoted dealer prices for similar contracts in active over-the-counter markets.

        Interest rate swaps—The fair value of interest rate swaps were determined using quoted dealer prices for similar contracts in active over-the-counter markets.

        The following methods and assumptions were used to estimate the fair value for which the fair value option was not elected:

        Cash and cash equivalents, receivables and accounts payable—The carrying amounts reported in the balance sheet approximate fair value.

        Debt—Debt associated with the Company's 2011 term loan A and term loan B in the amount of $894.8 million and $1.333 billion , respectively, at both March 31, 2012 and December 31, 2011 is carried at cost. Debt associated with the Company's revolving credit facility in the amount of $75.1 million at March 31, 2012 and $10.0 million at December 31, 2011 is carried at cost. The estimated fair value of the Company's term loan A, term loan B and Revolver was $886.8 million, $1.326 billion and $74.2 million at March 31, 2012, respectively, and $880.6 million, $1.319 billion and $9.7 million at December 31, 2011, respectively, based on similar transactions and yields in an active market for similarly rated debt (Level 2).
