Derivative Instruments [Abstract] |
Derivative Instruments and Hedging Activities Disclosure [Text Block] | Derivative Instruments In February 2008, the Company entered into an interest rate swap to fix the LIBOR-based variable portion of the interest rate on $125.0 million notional amount of its term loan facility at 2.73% through October 2009. In January 2009, the Company entered into two additional interest rate swaps. The first of these interest rate swaps fixed the LIBOR-based variable portion of the interest rate on $75.0 million notional amount of its term loan facility at 1.39% through January 2011. The second of these interest rate swaps was effective in October 2009 and fixed the LIBOR-based variable portion of the interest rate on $125.0 million notional amount of its term loan facility at 1.91% through July 2011. At inception, the Company formally designated these interest rate swaps as cash flow hedges. However, upon the Company's amendment and restatement of its credit facilities in the fourth quarter of 2009, the Company determined the interest rate swaps were no longer effective economic hedges due to the imposition of a LIBOR floor in the determination of the term loan facility variable interest rate component. In the first quarter of 2010, the Company amended the interest rate swaps to include a LIBOR floor similar to the term loan facility; however, the amended interest rate swaps were not designated as hedging instruments. Up to the date of the credit facility refinance in 2009, the Company had utilized hedge accounting, which allows for the effective portion of the interest rate swaps to be recorded in accumulated other comprehensive income in the accompanying consolidated balance sheet. At the date of the 2009 credit facility refinance, the Company had $1.7 million (net of tax of $1.1 million) of unrealized loss in accumulated other comprehensive income related to the interest rate swaps, which, due to the swaps no longer being effective hedges, was frozen and all subsequent changes in the fair value of the interest rate swaps recorded directly in interest expense in the statement of operations. The previously-effective amount frozen in accumulated other comprehensive income was amortized into earnings during the period in which the originally hedged transactions would have affected earnings. As of December 31, 2009, the Company held a foreign exchange forward contract with a notional value of 55.5 million Mexican pesos and a foreign exchange forward contract with a notional value of £6.5 million. These contracts expired during first quarter of 2010 and were not designated as hedging instruments. As of December 31, 2011 and 2010, the fair value carrying amounts of the Company's derivative instruments are recorded as follows:
