11. Fair Value Measurements

The carrying amounts reported for cash and cash equivalents, accounts receivable, other current assets, accounts payable and other current liabilities approximate fair value because of the short-term maturity of these instruments.

 

The carrying amounts and fair values of the Company’s Amended and Restated Senior Credit Facility, 12.875% Senior Notes, 6.125% Senior Notes, 9.0% and 9.5% Revenue Bonds and contingent consideration liability as of December 31, 2013 and 2012 were as follows (in thousands):

 

     Carrying Amount      Fair Value

Contingent consideration liability

   $ 6,500       $ 6,120       $ 6,500       $ 6,120   

The Company’s Amended and Restated Senior Credit Facility, 12.875% Senior Notes, 6.125% Senior Notes and 9.0% and 9.5% Revenue Bonds were categorized as Level 2 in the GAAP fair value hierarchy. Fair values were based on trading activity among the Company’s lenders and the average bid and ask price as determined using published rates.

The fair value of the contingent consideration liability at December 31, 2013 was categorized as Level 3 in the GAAP fair value hierarchy. The contingent consideration liability was valued using a probability-weighted discounted cash flow method. This analysis reflected the contractual terms of the purchase agreements and utilized assumptions with regard to future earnings, probabilities of achieving such future earnings and a discount rate. Significant increases with respect to assumptions as to future earnings and probabilities of achieving such future earnings would result in higher fair value measurement while an increase in the discount rate would result in a lower fair value measurement. During the year ended December 31, 2013, the Company changed its projections of the timing of future payments. This change resulted in a $0.4 million increase in the fair value of the contingent consideration liability, which was recorded in transaction-related expenses in the consolidated statements of operations.
