Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	DERIVATIVE FINANCIAL INSTRUMENTS The Company is exposed to certain risks relating to its ongoing business operations, including market risks relating to fluctuations in foreign currency exchange rates and interest rates. Derivative financial instruments are reported on the Consolidated Balance Sheets at fair value. Changes in the fair values of derivatives are reported each period in earnings or accumulated other comprehensive income, depending on whether a derivative is effective as part of a hedged transaction. Gains and losses on derivative instruments reported in accumulated other comprehensive income are subsequently included in earnings in the periods in which earnings are affected by the hedged item. The Company does not use derivative instruments for speculative purposes. The Company held forward exchange contracts designed to hedge forecasted transactions denominated in foreign currencies and to minimize the impact of foreign currency fluctuations on the Company’s earnings and cash flows. Some of those contracts were designated as cash flow hedges. The Company will include in earnings amounts currently included in accumulated other comprehensive income upon recognition of cost of sales related to the underlying transaction. Cash Flow Hedges Interest Rate Swaps The Company’s Term Loan Facility (“Term Loan”) contains floating rate obligations and is subject to interest rate fluctuations. During 2015, the Company entered into interest rate swap agreements for the purposes of hedging the eight quarterly variable-rate Term Loan interest payments due in 2016 and 2017. Additionally, the Company entered into interest rate swap agreements to effectively convert $83.8 million of our variable rate revolving credit facility debt to a fixed interest rate. These interest rate swap agreements were designated as cash flow hedges and intended to manage interest rate risk associated with our variable-rate borrowings and minimize the impact on our earnings and cash flows of interest rate fluctuations attributable to changes in LIBOR rates. These agreements were not material to the Company's Consolidated Balance Sheets for the years ended December 31, 2017 and 2016. As of December 31, 2017, these interest rate swap agreements had all matured and were no longer outstanding. The activity related to these contracts was not material to the Company's Consolidated Financial Statements for the year ended December 31, 2017. The Company reclassified $0.9 million of expense from other comprehensive income for the year ended 2016, respectively. No amounts related to cash flow hedges are expected to be reclassified from other comprehensive income over the next twelve months. 5. DERIVATIVE FINANCIAL INSTRUMENTS (CONTINUED) Derivatives Not Designated as Hedges Forward Exchange Contracts From time to time, the Company will enter into foreign exchange contracts that are not designated as hedging instruments.

During the fourth quarter of 2015, the Company entered into forward exchange contracts to minimize the impact of foreign currency fluctuations on the Company's earnings and cash flows.

For the year ended December 31, 2015, the Company reported expense of $2.2 million in Other (income) expense, net related to the change in the value of these contracts from the date the Company entered into them to their settlement date. At the settlement date, the Company took delivery of the Euros and further decreases in the exchange rate resulted in expense of $0.8 million, reported in Other (income) expense, net for the period of time between the settlement of the contracts and the closing of the acquisition. In addition to the forward exchange contract mentioned above, the Company held forward exchange contracts to mitigate the risk associated with foreign currencies that were not designated as hedging instruments as of December 31, 2017 and 2016.
