Fair Value Measurements

Fair Value Measurements

We account for certain assets and liabilities at fair value, and categorize each of our fair value measurements in one of the following three levels based on the lowest level input that is significant to the fair value measurement in its entirety:

Level 1—Inputs to the valuation methodology are unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2—Observable inputs other than quoted prices in active markets for identical assets and liabilities include:

a) quoted prices for similar assets or liabilities in active markets;

b) quoted prices for identical or similar assets or liabilities in inactive markets;

c) inputs other than quoted prices that are observable for the asset or liability;

d) inputs that are derived principally from or corroborated by observable market data by correlation or other means.

If the asset or liability has a specified (contractual) term, the Level 2 input must be observable for substantially the full term of the asset or liability.

Level 3—Inputs to the valuation methodology are unobservable (i.e., supported by little or no market activity) and significant to the fair value measure.

Assets and Liabilities Measured at Fair Value

As of December 31, 2011 and 2010, our only assets and liabilities measured at fair value were our fixed price diesel swaps contracts, which are Level 2 derivatives measured at fair value on a recurring basis. As of December 31, 2011, $1 was reflected in accrued expenses and other liabilities in our consolidated balance sheets, reflecting the fair values of the fixed price diesel swaps contracts. As of December 31, 2010, less than $1 was reflected in prepaid expenses and other assets in our consolidated balance sheets reflecting the fair value of the fixed price diesel swaps contracts. As discussed in note 10 to the consolidated financial statements, we entered into the fixed price swap contracts on diesel purchases to mitigate the price risk associated with forecasted purchases of diesel. Fair value is determined based on observable market data. As of December 31, 2011, we have fixed price swap contracts that mature throughout 2012 covering 4.2 gallons of diesel which we will buy at the average contract price of $3.98 per gallon, while the average forward price for the hedged gallons was $3.79 per gallon as of December 31, 2011.

Fair Value of Financial Instruments

The carrying amounts reported in our consolidated balance sheets for accounts receivable, accounts payable and accrued expenses and other liabilities approximate fair value due to the immediate to short-term maturity of these financial instruments. The fair values of our senior secured asset-based revolving credit facility (“ABL facility”), accounts receivable securitization facility and 1 ⁷/8 percent Convertible Senior Subordinated Notes approximate their book values as of December 31, 2011 and 2010. The estimated fair values of our other financial instruments at December 31, 2011 and 2010 have been calculated based upon available market information or an appropriate valuation technique, and are as follows:

	December 31, 2011				December 31, 2010
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Subordinated convertible debentures	$	55	$	49	$	124	$	92
Senior and senior subordinated notes	1,861		1,933		1,854		2,020
Capital leases (1)	39		33		25		20

(1)    The fair value of capital leases is determined using the expected present value of the leases.
