Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	DERIVATIVES General. Our earnings and cash flows are subject to fluctuations due to changes in interest rates and foreign currency exchange rates, and we seek to mitigate a portion of these risks by entering into derivative contracts. The derivatives we use are an interest rate swap and forward contracts. We recognize derivatives as either assets or liabilities at fair value in the accompanying consolidated balance sheets, regardless of whether or not hedge accounting is applied. We report cash flows arising from our hedging instruments consistent with the classification of cash flows from the underlying hedged items. Accordingly, cash flows associated with our derivative programs are classified as operating activities in the accompanying consolidated statements of cash flows. We formally document, designate and assess the effectiveness of transactions that receive hedge accounting initially and on an ongoing basis. Changes in the fair value of derivatives that qualify for hedge accounting treatment are recorded, net of applicable taxes, in accumulated other comprehensive income (loss), a component of stockholders’ equity in the accompanying consolidated balance sheets. For the ineffective portions of qualifying hedges, the change in fair value is recorded through earnings in the period of change. Changes in the fair value of derivatives not designated as cash flow hedges are recorded in earnings throughout the term of the derivative instrument. Interest Rate Swap. A portion of our debt bears interest at variable interest rates and therefore, we are subject to variability in the cash paid for interest expense. In order to mitigate a portion of this risk, we used a hedging strategy to reduce the variability of cash flows in the interest payments associated with the first $55 million of the total variable-rate debt outstanding under our Credit Agreement that was solely due to changes in the benchmark interest rate. This strategy allowed us to fix a portion of our interest payments. On October 25, 2010, we entered into a $55 million pay-fixed, receive-variable interest rate swap with Wells Fargo at a fixed interest rate of 2.73%. The variable portion of the interest rate swap was tied to the one-month LIBOR rate (the benchmark interest rate). The interest rates under both the interest rate swap and the underlying debt reset, the swap was settled with the counterparty, and interest was paid, on a monthly basis. The interest rate swap was scheduled to expire on September 10, 2015. This interest rate swap qualified as a cash flow hedge. At December 31, 2010, the interest rate swap qualified as a cash flow hedge. The fair value of our interest rate swap at December 31, 2010 was approximately $1.2 million, which was offset by approximately $451,000 of deferred tax liability. On July 7, 2011, we terminated our interest rate swap agreement, which resulted in a cash receipt of and gain of approximately $28,000 upon final settlement. During the years ended December 31, 2011 and 2010, the amount reclassified from accumulated other comprehensive income to earnings due to hedge effectiveness was approximately $73,000 and $20,000, respectively, which is included in interest expense in the accompanying consolidated statements of income. Foreign Currency Forward Contracts. On November 30, 2011, we forecasted a net exposure for December 31, 2011 (representing the difference between Euro and GBP-denominated receivables and Euro-denominated payables) of approximately 12,000 Euros and 328,000 GBPs. In order to partially offset such risks at November 30, 2011, we entered into a 30-day forward contract for the Euro and GBP with a notional amount of approximately 12,000 Euros and notional amount of 328,000 GBPs. On November 30, 2010, we forecasted a net exposure for December 31, 2010 (representing the difference between Euro and GBP-denominated receivables and Euro-denominated payables) of approximately 658,000 Euros and 222,000 GBPs. In order to partially offset such risks at November 30, 2010, we entered into a 30-day forward contract for the Euro and GBP with a notional amount of approximately 658,000 Euros and notional amount of 222,000 GBPs. We enter into similar transactions at various times during the year to partially offset exchange rate risks we bear throughout the year. These contracts are marked to market at each month-end. During the years ended December 31, 2011, 2010 and 2009, we recorded a net gain on all forward contracts of approximately $221,000, $126,000 and $83,000, respectively, which is included in other income in the accompanying consolidated statements of income. The fair value of our open positions at December 31, 2011 and 2010 was not material.

DERIVATIVES

General. Our earnings and cash flows are subject to fluctuations due to changes in interest rates and foreign currency exchange rates, and we seek to mitigate a portion of these risks by entering into derivative contracts. The derivatives we use are an interest rate swap and forward contracts. We recognize derivatives as either assets or liabilities at fair value in the accompanying consolidated balance sheets, regardless of whether or not hedge accounting is applied. We report cash flows arising from our hedging instruments consistent with the classification of cash flows from the underlying hedged items. Accordingly, cash flows associated with our derivative programs are classified as operating activities in the accompanying consolidated statements of cash flows.

We formally document, designate and assess the effectiveness of transactions that receive hedge accounting initially and on an ongoing basis. Changes in the fair value of derivatives that qualify for hedge accounting treatment are recorded, net of applicable taxes, in accumulated other comprehensive income (loss), a component of stockholders’ equity in the accompanying consolidated balance sheets. For the ineffective portions of qualifying hedges, the change in fair value is recorded through earnings in the period of change. Changes in the fair value of derivatives not designated as cash flow hedges are recorded in earnings throughout the term of the derivative instrument.

Interest Rate Swap. A portion of our debt bears interest at variable interest rates and therefore, we are subject to variability in the cash paid for interest expense. In order to mitigate a portion of this risk, we used a hedging strategy to reduce the variability of cash flows in the interest payments associated with the first $55 million of the total variable-rate debt outstanding under our Credit Agreement that was solely due to changes in the benchmark interest rate.

At December 31, 2010, the interest rate swap qualified as a cash flow hedge.
