Interest Rate Swap [Abstract] |
Interest Rate Swap | Interest Rate Swap In May 2011, the Company entered into $250,000 notional amount of interest rate swap agreements (Swap Agreements) that are scheduled to expire June 1, 2017. Under the Swap Agreements, the Company receives a fixed rate of 5.75% and pays a variable rate of the three month LIBOR plus 3.5% adjusted quarterly, which allows the Company to adjust $250,000 of its senior notes to a floating rate. The Company does not hold or issue any derivative instrument for trading or speculative purposes. At December 31, 2013, the variable rate was 3.74%. The Swap Agreements are formally designated and qualify as fair value hedges. The Swap Agreements are recorded at fair value in the Consolidated Balance Sheet in other assets or other liabilities. Gains and losses due to changes in fair value of the interest rate swaps completely offset changes in the fair value of the hedged portion of the underlying debt. Therefore, no gain or loss has been recognized due to hedge ineffectiveness. Offsetting changes in fair value of both the interest rate swaps and the hedged portion of the underlying debt both were recognized in interest expense in the Consolidated Statement of Operations. The fair value of the Swap Agreements as of December 31, 2013 was an asset of approximately $9,576, and is included in other long term assets in the Consolidated Balance Sheet. The fair value of the Swap Agreements excludes accrued interest and takes into consideration current interest rates and current likelihood of the swap counterparties' compliance with its contractual obligations.
