We enter into foreign currency forward and option contracts to offset the earnings impact that foreign exchange rate fluctuations would otherwise have on certain monetary liabilities that are denominated in nonfunctional currencies.

Cash Flow Hedging Instruments

We enter into foreign currency forward contracts that are designated as cash flow hedges. The settlement of these derivatives results in reclassifications from accumulated other comprehensive loss to earnings for the period in which the settlement of these instruments occurs. The maximum period for which we hedge our cash flow using these instruments is

12 months

. Accordingly, at September 30, 2019, all our open foreign currency forward contracts had maturities of

one year or less

. The total notional value of our foreign currency exchange contracts designated as cash flow hedges at September 30, 2019 was $40,400, and such contracts have varying terms expiring through June 2020.

The impact from foreign exchange derivative instruments designated as cash flow hedges was as follows:


	Quarter Ended September 30,						Nine Months Ended September 30,
	2019			2018			2019			2018
Gain (loss) recorded in accumulated other comprehensive loss	$	351		$	316		$	(1,093	)	$	1,043
Gain reclassified from accumulated other comprehensive loss into earnings	$	(191	)	$	(1,253	)	$	(742	)	$	(78	)

At September 30, 2019, we expected an estimated $385

pre-tax

loss

to be reclassified into earnings to reflect the fixed prices obtained from foreign exchange hedging within the next 12 months.

Derivatives Not Designated as Hedging Instruments

We have also entered into foreign currency forward and option contracts that are either not designated as hedges or did not qualify for hedge accounting. These derivative instruments were effective economic hedges for all the periods presented. The fair value gains and losses on these contracts are recognized in earnings as a component of selling, general and administrative expenses. The total notional value of our foreign currency exchange contracts not designated as hedging instruments at September 30, 2019 was $12,300, and such contracts have varying terms expiring through November 2019.

We recognized

from foreign currency forward and option contracts not designated as hedging instruments in our condensed consolidated unaudited statements of income for the quarters ended September 30, 2019 and 2018, respectively. We recognized losses of $175 and $299 from foreign currency forward and option contracts not designated as hedging instruments in our condensed consolidated unaudited statements of income for the nine months ended September 30, 2019 and 2018, respectively.
