The Company enters into derivative instruments for risk management purposes only, including derivatives designated as hedging instruments and those utilized as economic hedges. The Company operates internationally and, in the normal course of business, is exposed to fluctuations in interest rates and foreign exchange rates. These fluctuations can increase the costs of financing, investing and operating the business. The Company has used derivative instruments, such as forward foreign currency exchange contracts, to manage certain foreign currency exposure, and interest rate swaps to manage interest rate exposure.

By nature, all financial instruments involve market and credit risks. The Company enters into derivative instruments with major investment grade financial institutions, for which no collateral is required. The Company has policies to monitor the credit risk of these counterparties. While there can be no assurance, the Company does not anticipate any material

non-performance

by any of these counterparties.

Interest Rate Swap Agreements

On September 30, 2016, the Company entered into an interest rate swap agreement to fix the rate on approximately

% of its then-outstanding balance under the Credit Agreement, as described further in Note 11. This hedge fixes the interest rate paid on the hedged debt at

1.198

% per annum plus the applicable credit spread, which was

2.0

% as of June 30, 2019, through

September 30, 2020

At June 30, 2019, the notional amount of this transaction was

$290,000

and had a fair value asset of

$2,055.

At December 31, 2018, the notional amount of this transaction was

$290,000 and had a fair value asset of $6,083.

On April 3, 2019, the Company entered into an interest rate swap agreement, which has a maturity date of March 31, 2023, to fix the rate on $

300,000

of the then-outstanding balance of the 2019 Incremental Term Loan Facility, as described further in Note 11. The rate is fixed at

2.309

% per annum plus the applicable credit spread, which was

2.25

% at June 30, 2019. At June 30, 2019, the notional amount of this transaction was $

300,000

and had a fair value liability of $

6,688

The interest rate swaps are recorded at fair value on the balance sheet and changes in the fair value are recognized in other comprehensive income (loss) (“OCI”). To the extent that these arrangements are no longer an effective hedge, any ineffectiveness measured in the hedging relationships is recorded currently in earnings in the period it occurs.

Foreign Exchange Contracts

The Company hedges a portion of its forecasted foreign currency-denominated intercompany sales of inventory, over a maximum period of

eighteen months

, using forward foreign exchange contracts accounted for as cash-flow hedges related to Japanese, South Korean, British, Euro and Taiwanese currencies. To the extent these derivatives are effective in off-setting the variability of the hedged cash flows, and otherwise meet the hedge accounting criteria, changes in the derivatives’ fair value are not included in current earnings but are included in OCI in stockholders’ equity. These changes in fair value will subsequently be reclassified into earnings, as applicable, when the forecasted transaction occurs. To the extent that a previously designated hedging transaction is no longer an effective hedge, any ineffectiveness measured in the hedging relationship is recorded currently in earnings in the period it occurs. The cash flows resulting from forward exchange contracts are classified in the consolidated statements of cash flows as part of cash flows from operating activities. The Company does not enter into derivative instruments for trading or speculative purposes.

As of June 30, 2019 and December 31, 2018, the Company had outstanding forward foreign exchange contracts with gross notional values of $

161,278

and $

159,394

, respectively.
