Historically, we have entered into forward contracts to hedge our exposures associated with certain foreign currencies. As of December 31, 2017, we had outstanding forward contracts to (i) purchase 138,823 United States dollars and sell 176,000 Canadian dollars, (ii) purchase 135,000 Euros and sell 160,757 United States dollars and (iii) purchase 114,390 United States dollars and sell 96,150 Euros to hedge our foreign exchange exposures. As of September 30, 2018, we had outstanding forward contracts to purchase 30,000 Euros and sell 35,436 United States dollars. We have not designated any of the forward contracts we have entered into as hedges.

Net cash receipts (payments) included in cash from operating activities related to settlements associated with foreign currency forward contracts for the three and nine months ended September 30, 2017 and 2018 are as follows:



	Three Months Ended September 30,					Nine Months Ended September 30,
	2017		2018			2017		2018
Net cash receipts (payments)	$	7,643	$	(3,347	)	$	8,536	$	(4,558	)

Our policy is to record the fair value of each derivative instrument on a gross basis. The following table provides the fair value of our derivative instruments not designated as hedging instruments as of December 31, 2017 and September 30, 2018:



Derivatives Not Designated as Hedging Instruments	Balance Sheet Location	December 31, 2017		September 30, 2018
Derivative assets	Prepaid expenses and other	$	1,579	$	—
Derivative liabilities	Accrued expenses	2,329		365

(Gains) losses for our derivative instruments not recognized as hedging instruments for the three and nine months ended September 30, 2017 and 2018 are as follows:



		Three Months Ended September 30,					Nine Months Ended September 30,
Derivatives Not Designated as Hedging Instruments	Location of Loss (Gain) Recognized in Income on Derivative	2017			2018		2017			2018
Foreign exchange contracts	Other (income) expense, net	$	(5,748	)	$	616	$	(9,316	)	$	4,172

We have designated a portion of our (i) Euro denominated borrowings by IMI under our Former Revolving Credit Facility and (ii) Euro Notes as a hedge of net investment of certain of our Euro denominated subsidiaries. For the nine months ended September 30, 2017, we designated, on average, 84,443 Euros of our Euro denominated borrowings by IMI under our Former Revolving Credit Facility as a hedge of net investment of certain of our Euro denominated subsidiaries. For the nine months ended September 30, 2018, we designated, on average, 209,276 Euros of our Euro Notes as a hedge of net investment of certain of our Euro denominated subsidiaries. As a result, we recorded the following foreign exchange (losses) gains related to the change in fair value of such debt due to currency translation adjustments, which is a component of accumulated other comprehensive items, net:



	Three Months Ended September 30,					Nine Months Ended September 30,
	2017			2018		2017			2018
Foreign exchange (losses) gains	$	(4,211	)	$	2,139	$	(12,359	)	$	6,761

As of September 30, 2018, cumulative net gains of $9,949, net of tax, are recorded in accumulated other comprehensive items, net associated with this net investment hedge.

In March 2018, we entered into interest rate swap agreements to limit our exposure to changes in interest rates on a portion of our floating rate indebtedness. As of September 30, 2018, we have $350,000 in notional value of interest rate swap agreements outstanding, which expire in March 2022. Under the interest rate swap agreements, we receive variable rate interest payments associated with the notional amount of each interest rate swap, based upon one-month LIBOR, in exchange for the payment of fixed interest rate payments (at the fixed rate interest specified in the interest rate swap agreements). We have designated these interest rate swaps as cash flow hedges. Unrealized gains are recognized as assets while unrealized losses are recognized as liabilities. The fair value of the interest rate swaps are estimated using industry standard valuation models using market-based observable inputs, including interest rate curves (Level 2, as described in Note 2.g.). At September 30, 2018, we had a derivative asset of $4,183, which was recorded as a component of Other within Other assets, net in our Condensed Consolidated Balance Sheet, which represents the fair value of our interest rate swap agreements.

We have recorded the change in fair value of the interest rate swap agreements to accumulated other comprehensive income. We have recorded unrealized gains of $1,980 and $4,183 for the three and nine months ended September 30, 2018, respectively, associated with our interest rate swap agreements. At September 30, 2018, we have recorded cumulative unrealized gains of $4,183 within accumulated other comprehensive items, net associated with these agreements.
