Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Derivatives. Interest Rate Swap. On December 19, 2012, we entered into a pay-fixed, receive-variable interest rate swap having an initial notional amount of $150 million with Wells Fargo to fix the one-month LIBOR rate at 0.98%. The variable portion of the interest rate swap is 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 is settled with the counterparty, and interest is paid, on a monthly basis. The notional amount of the interest rate swap is reduced quarterly by 50% of the minimum principal payment due under the terms of the Credit Agreement. The interest rate swap is scheduled to expire on December 19, 2017. As of March 31, 2014, our interest rate swap qualified as a cash flow hedge. The fair value of our interest rate swap at March 31, 2014 was an asset of approximately $1.1 million, which was offset by approximately $438,000 in deferred taxes. During the three months ended March 31, 2014 and 2013, the amount reclassified from accumulated other comprehensive income to earnings due to hedge effectiveness was included in interest expense in the accompanying consolidated statements of income and was not material. Foreign Currency Forward Contracts. On February 28, 2014, we forecasted a net foreign currency exposure for March 31, 2014 (representing the difference between Euro and GBP-denominated receivables and Euro-denominated payables) of approximately 966,000 Euros and 652,000 GBPs. In order to partially offset such risks at February 28, 2014, we entered into a 30-day forward contract for the Euro and GBP with a notional amount of approximately 966,000 Euros and notional amount of 652,000 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 the end of each month. The effect on our consolidated statements of income for the three months ended March 31, 2014 and 2013 of all forward contracts, and the fair value of our open positions as of March 31, 2014, were not material.
