FINANCIAL INSTRUMENTS	FINANCIAL INSTRUMENTS The Company has limited involvement with derivative financial instruments and does not use them for trading purposes. The Company enters into certain interest rate swap agreements in order to manage its exposure to changes in interest rates. The amount of the Company's fixed obligation interest payments may change based upon the expiration dates of its interest rate swap agreements and the level and composition of its debt. The Company also enters into certain foreign currency forward contracts to limit the Company's exposure to currency fluctuations on the respective hedged items. As also mentioned in Note 7, the Company has designated its euro denominated debt as a hedge of a portion of its net investment in euro-denominated foreign operations. For additional disclosures on the fair value of financial instruments, see Note 5 to the interim consolidated financial statements. Cash Flow Hedges In June 2017, the Company entered into a cross currency swap arrangement designated as a cash flow hedge. The agreement converts $100 million of borrowings under the Company's credit facility into synthetic Swiss franc debt which allows the Company to effectively change the floating rate LIBOR-based interest payment to a fixed Swiss franc income of 0.01%. The swap began in June 2017 and matures in June 2019. The Company has an interest rate swap agreement designated as a cash flow hedge. The agreement is a swap which has the effect of changing the floating rate LIBOR-based interest payments associated with $50 million of borrowings under the Company’s credit facility to a fixed obligation of 2.52%. The swap began in October 2015 and matures in October 2020. In March 2015, the Company entered into a forward-starting interest rate swap agreement. The agreement is a swap which has the effect of changing the floating rate LIBOR-based interest payments associated with $100 million of borrowings under the Company's credit agreement to a fixed obligation of 2.25% beginning in February 2017 and matures in February 2022. The Company's cash flow hedges are recorded gross at fair value in the consolidated balance sheet at June 30, 2018 and December 31, 2017, respectively, and disclosed in Note 5 to the consolidated financial statements. Amounts reclassified into other comprehensive income and the effective portions of the cash flow hedges are further disclosed in Note 9 to the consolidated financial statements. A derivative gain of $3.1 million based upon interest rates and foreign currency rates at June 30, 2018, is expected to be reclassified from other comprehensive income (loss) to earnings in the next twelve months. Through June 30, 2018, no hedge ineffectiveness has occurred in relation to the cash flow hedges. Other Derivatives The Company enters into foreign currency forward contracts in order to economically hedge short-term trade and non-trade intercompany balances largely denominated in Swiss franc, other major European currencies, and the Chinese Renminbi with its foreign businesses. In accordance with U.S. GAAP, these contracts are considered “derivatives not designated as hedging instruments.” Gains or losses on these instruments are reported in current earnings. The foreign currency forward contracts are recorded at fair value in the consolidated balance sheet at June 30, 2018 and December 31, 2017, respectively, and disclosed in Note 5. The Company recognized in other charges (income), a net loss of $1.5 million and a net gain of $0.1 million during the three months ended June 30, 2018 and 2017, respectively, and a net gain of $4.2 million and $1.9 million during the six months ended June 30, 2018 and 2017, respectively. The gains and losses are primarily offset by the underlying transaction gains and losses on the related intercompany balances. At June 30, 2018 and December 31, 2017, these contracts had a notional value of $407.1 million and $394.8 million, respectively.
