9.	Derivative Instruments

Certain of the Corporation’s operations are subject to risk from exchange rate fluctuations in connection with sales in foreign currencies. To minimize this risk, foreign currency sales contracts are entered into which are designated as cash flow or fair value hedges. As of September 30, 2018, approximately $34,130 of anticipated foreign-denominated sales has been hedged which are covered by fair value contracts settling at various dates through January 2020.

Additionally, certain of the divisions of the Air and Liquid Processing segment are subject to risk from increases in the price of commodities (copper and aluminum) used in the production of inventory. To minimize this risk, futures contracts are entered into which are designated as cash flow hedges. At September 30, 2018, approximately 51% or $2,682 of anticipated copper purchases over the next 10 months and 56% or $540 of anticipated aluminum purchases over the next six months are hedged.

The Corporation previously entered into foreign currency purchase contracts to manage the volatility associated with Euro-denominated progress payments to be made for certain machinery and equipment. As of December 31, 2010, all contracts had been settled and the underlying fixed assets were placed in service.

No portion of the existing cash flow or fair value hedges is considered to be ineffective, including any ineffectiveness arising from the unlikelihood of an anticipated transaction to occur. Additionally, no amounts have been excluded from assessing the effectiveness of a hedge.

As of September 30, 2018, the Corporation has purchase commitments covering 47% or $235 of anticipated natural gas usage for the remainder of 2018 for one of its subsidiaries. The commitments qualify as normal purchases and, accordingly, are not reflected on the condensed consolidated balance sheet. Purchases of natural gas under previously existing commitments approximated $233 and $1,051, respectively, for the three and nine months ended September 30, 2018. There were no purchases of natural gas under previously existing commitments for the three and nine months ended September 30, 2017.

The Corporation does not enter into derivative transactions for speculative purposes and, therefore, holds no derivative instruments for trading purposes.

(Losses) gains on foreign exchange transactions included in other income (expense) approximated $(5) and $87 for the three months ended September 30, 2018, and 2017, respectively, and $(1,707) and $(616) for the nine months ended September 30, 2018, and 2017, respectively.

The location and fair value of the foreign currency sales contracts recorded on the condensed consolidated balance sheets were as follows:

	Location	September 30, 2018		December 31, 2017

The change in the fair value of the cash flow contracts is recorded as a component of accumulated other comprehensive loss. The balances as of September 30, 2018, and 2017, and the amount recognized as and reclassified from accumulated other comprehensive loss for each of the periods is summarized below. Amounts recognized as comprehensive income (loss) and reclassified from accumulated other comprehensive loss have no tax effect due to deferred income tax assets being fully valued in the related jurisdictions.
