Derivative Financial Instruments

As part of our risk management strategy, we use derivative instruments to hedge certain foreign currency and interest rate exposures. Refer to Note 13 and Note 14 for additional disclosures on our derivative instruments.

The fair values of our derivative instruments are determined using the income approach and significant other observable inputs (also known as "Level 2"). We have used observable market inputs based on the type of derivative and the nature of the underlying instrument. The key inputs include interest rate yield curves (swap rates and futures) and foreign exchange spot and forward rates, all of which are available in an active market. We have utilized the mid-market pricing convention for these inputs. We include, as a discount to the derivative asset, the effect of our counterparty credit risk based on current published credit default swap rates when the net fair value of our derivative instruments is in a net asset position. We consider our own nonperformance risk when the net fair value of our derivative instruments is in a net liability position by discounting our derivative liabilities to reflect the potential credit risk to our counterparty through applying a current market indicative credit spread to all cash flows.

The fair values of our derivative instruments were as follows:



		Fair Value
Asset Derivatives	Balance Sheet Location	March 31, 2018		December 31, 2017
Derivatives designated as hedging instruments under ASC 815-20		(in thousands)
Interest rate swap contracts	Other current assets	$	1,303	$	658
Interest rate cap contracts	Other current assets	74		17
Interest rate swap contracts	Other long-term assets	2,226		1,712
Interest rate cap contracts	Other long-term assets	310		179
Derivatives not designated as hedging instruments under ASC 815-20
Foreign exchange forward contracts	Other current assets	44		41
Interest rate cap contracts	Other current assets	111		25
Interest rate cap contracts	Other long-term assets	464		268
Total asset derivatives		$	4,532	$	2,900

Liability Derivatives
Derivatives not designated as hedging instruments under ASC 815-20
Foreign exchange forward contracts	Other current liabilities	$	356	$	289

The changes in accumulated other comprehensive income (loss) (AOCI), net of tax, for our derivative and nonderivative hedging instruments, were as follows:



	2018			2017
	(in thousands)
Net unrealized gain (loss) on hedging instruments at January 1,	$	(13,414	)	$	(14,337	)
Unrealized gain (loss) on hedging instruments	1,183			60
Realized loss (gain) reclassified into net income	(14		)	232
Net unrealized gain (loss) on hedging instruments at March 31,	$	(12,245	)	$	(14,045	)

Reclassification of amounts related to hedging instruments are included in interest expense in the Consolidated Statements of Operations for the periods ended March 31, 2018 and 2017. Included in the net unrealized loss on hedging instruments at March 31, 2018 and 2017 is a loss of $14.4 million, net of tax, related to our nonderivative net investment hedge, which terminated in 2011. This loss on our net investment hedge will remain in AOCI until such time when earnings are impacted by a sale or liquidation of the associated foreign operation.

A summary of the effect of netting arrangements on our financial position related to the offsetting of our recognized derivative assets and liabilities under master netting arrangements or similar agreements is as follows:



Offsetting of Derivative Assets	Gross Amounts of Recognized Assets Presented in the Consolidated Balance Sheets		Gross Amounts Not Offset in the Consolidated Balance Sheets
			Derivative Financial Instruments			Cash Collateral Received		Net Amount
	(in thousands)
March 31, 2018	$	4,532	$	(128	)	$	—	$	4,404

December 31, 2017	$	2,900	$	(90	)	$	—	$	2,810



Offsetting of Derivative Liabilities	Gross Amounts of Recognized Liabilities Presented in the Consolidated Balance Sheets		Gross Amounts Not Offset in the Consolidated Balance Sheets
			Derivative Financial Instruments			Cash Collateral Pledged		Net Amount
	(in thousands)
March 31, 2018	$	356	$	(128	)	$	—	$	228

December 31, 2017	$	289	$	(90	)	$	—	$	199

Our derivative assets and liabilities subject to netting arrangements consist of foreign exchange forward and interest rate contracts with three counterparties at March 31, 2018 and December 31, 2017. No derivative asset or liability balance with any of our counterparties was individually significant at March 31, 2018 or December 31, 2017. Our derivative contracts with each of these counterparties exist under agreements that provide for the net settlement of all contracts through a single payment in a single currency in the event of default. We have no pledges of cash collateral against our obligations nor have we received pledges of cash collateral from our counterparties under the associated derivative contracts.

Cash Flow Hedges

As a result of our floating rate debt, we are exposed to variability in our cash flows from changes in the applicable interest rate index. We enter into interest rate caps and swaps to reduce the variability of cash flows from increases in the LIBOR based borrowing rates on our floating rate credit facility. These instruments do not protect us from changes to the applicable margin under our credit facility. At March 31, 2018, our LIBOR-based debt balance was $690.0 million.

In October 2015, we entered into an interest rate swap, which is effective from August 31, 2016 to June 23, 2020, and converts $214 million of our LIBOR based debt from a floating LIBOR interest rate to a fixed interest rate of 1.42% (excluding the applicable margin on the debt). The notional balance will amortize to maturity at the same rate as required minimum payments on our term loan. The cash flow hedge is expected to be highly effective in achieving offsetting cash flows attributable to the hedged risk through the term of the hedge. Consequently, effective changes in the fair value of the interest rate swap is recognized as a component of other comprehensive income (OCI) and will be recognized in earnings when the hedged item affects earnings. The amounts paid or received on the hedge are recognized as an adjustment to interest expense. The amount of net gains expected to be reclassified into earnings in the next 12 months is $1.3 million.

In November 2015, we entered into three interest rate cap contracts with a total notional amount of $100 million at a cost of $1.7 million. The interest rate cap contracts expire on June 23, 2020 and were entered into in order to limit our interest rate exposure on $100 million of our variable LIBOR based debt up to 2.00%. In the event LIBOR is higher than 2.00%, we will pay interest at the capped rate of 2.00% with respect to the $100 million notional amount of such agreements. As of December 31, 2016, due to the accelerated revolver payments from surplus cash, we elected to de-designate two of the interest rate cap contracts as cash flow hedges and discontinued the use of cash flow hedge accounting. The amounts recognized in AOCI from de-designated interest rate cap contracts will continue to be reported in AOCI unless it is not probable that the forecasted transactions will occur. As a result of the discontinuance of cash flow hedge accounting, all subsequent changes in fair value of the de-designated derivative instruments are recognized within interest expense instead of OCI. The amount of net losses expected to be reclassified into earnings for all interest rate cap contracts in the next 12 months is $0.3 million.

The before-tax effects of our derivative instruments designated as hedges on the Consolidated Balance Sheets and the Consolidated Statements of Operations were as follows:

Derivatives Not Designated as Hedging Relationships

We are also exposed to foreign exchange risk when we enter into non-functional currency transactions, both intercompany and third party. At each period-end, non-functional currency monetary assets and liabilities are revalued with the change recognized to other income and expense. We enter into monthly foreign exchange forward contracts, which are not designated for hedge accounting, with the intent to reduce earnings volatility associated with currency exposures. As of March 31, 2018, a total of 57 contracts were offsetting our exposures from the Euro, Saudi Riyal, Indian Rupee, Chinese Yuan, Indonesian Rupiah, and various other currencies, with notional amounts ranging from $93,000 to $47.5 million.

The effect of our derivative instruments not designated as hedges on the Consolidated Statements of Operations was as follows:
