Fair Value Measurements

Fair Value Measurements

We determine fair value measurements used in our condensed consolidated financial statements based upon 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. The fair value hierarchy distinguishes between (1) market participant assumptions developed based on market data obtained from independent sources (observable inputs) and (2) an entity’s own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs). The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are described below:

• Level 1 – Valuations based on quoted prices in active markets for identical assets or liabilities that the entity has the ability to access.

• Level 2 – Valuations based on quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable data for substantially the full term of the assets or liabilities.

• Level 3 – Valuations based on inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

We estimate the fair value of our long-term, fixed rate debt using a Level 3 discounted cash flow analysis based on current borrowing rates for debt with similar maturities. The fair value of our long-term debt, including current maturities, at June 30, 2012 and December 31, 2011 was approximately $73.2 million and $72.6 million, respectively. The carrying amount of such fixed-rate debt at June 30, 2012 and December 31, 2011 was $68.1 million and $67.5 million, respectively.
