See Note 16, Derivative Financial Instruments for additional information on the Company's interest rate swaps. Additionally, $5.2 million in obligations associated with acquired unfavorable contracts were recorded during the year related to acquisitions completed during 2011, which are being amortized over the remaining terms of the respective unfavorable contracts.
