Fair Value Disclosures [Abstract]  
Fair Value Measurements Fair Value Measurements
We measure on a recurring basis and disclose the fair value of our financial instruments under the provisions of ASC Topic 820, Fair Value Measurement, as amended (“ASC 820”). We define “fair value” as the price that would be received to sell an asset or paid to transfer a liability (i.e., the exit price) in an orderly transaction between market participants at the measurement date. ASC 820 establishes a three-level hierarchy for measuring fair value and requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. This valuation hierarchy is based upon the transparency of inputs used in the valuation of an asset or liability on the measurement date.
The three levels of that hierarchy are defined as follows:
Level 1 - Quoted prices are available in active markets for identical assets or liabilities;
Level 2 - Pricing inputs are other than quoted prices in active markets, included in Level 1, that are either directly or indirectly observable; and
Level 3 - Unobservable pricing inputs in which little or no market activity exists, therefore requiring an entity to develop its own model with estimates and assumptions.

Financial Instruments Measured at Fair Value on Recurring Basis
Consistent with the fair value hierarchy, we categorized our financial assets and liabilities as follows:

The fair value of each asset and liability was determined using widely accepted valuation techniques, including discounted cash flow analyses and observable inputs, such as market interest rates and foreign exchange rates.
Other Fair Value Disclosures
The carrying amounts, if any, of cash equivalents, trade and other accounts receivable, accounts payable, and borrowings under our $500 million asset-based senior secured loan facility (the “ABL Facility”) approximate their respective fair values due to the short-term nature of these financial instruments. The carrying amounts and corresponding estimated fair values of our long-term debt, excluding debt issuance costs and original issue discounts, are as follows:
