The Company’s interest rate risk relates to U.S. dollar denominated variable interest rate borrowings. The Company uses interest rate swap derivative instruments to manage earnings and cash flow exposure resulting from changes in interest rates. These interest rate swaps apply a fixed interest rate on a portion of the Company's expected LIBOR-indexed floating-rate borrowings.

The Company has designated these derivative instruments as cash flow hedges. The Company assesses the effectiveness of these derivative instruments and has recorded the changes in the fair value of the derivative instrument designated as a cash flow hedge as unrealized gains or losses in accumulated other comprehensive income (“AOCI”), net of tax, until the hedged item affected earnings, at which point any gain or loss was reclassified to earnings. If the hedged cash flow does not occur, or if it becomes probable that it will not occur, the Company will reclassify the remaining amount of any gain or loss on the related cash flow hedge recorded in AOCI to interest expense at that time.

From time to time, the Company enters into foreign currency hedge contracts intended to protect the U.S. dollar value of certain forecasted foreign currency denominated transactions. The Company assesses the effectiveness of the contracts that are designated as hedging instruments. The changes in fair value of foreign currency cash flow hedges are recorded in AOCI, net of tax. Those amounts are subsequently reclassified to earnings from AOCI as impacted by the hedged item when the hedged item affects earnings. If the hedged forecasted transaction does not occur, or if it becomes probable that it will not occur, the Company will reclassify the amount of any gain or loss on the related cash flow hedge to earnings at that time. For contracts not designated as hedging instruments, the changes in fair value of the contracts are recognized in other income, net in the consolidated statements of operation, along with the offsetting foreign currency gain or loss on the underlying assets or liabilities.

The success of the Company’s hedging program depends, in part, on forecasts of certain activity denominated in foreign currency. The Company may experience unanticipated currency exchange gains or losses to the extent that there are differences between forecasted and actual activities during periods of currency volatility. In addition, changes in currency exchange rates related to any unhedged transactions may affect earnings and cash flows.

On October 2, 2017, the Company entered into cross currency swap agreements to convert a notional amount of $300.0 million equivalent to 291.2 million of Swiss Francs ("CHF") denominated intercompany loans into U.S. dollars. The CHF- denominated intercompany loans were the result of the purchase of intellectual property by a subsidiary in Switzerland as part of an acquisition. On September 26, 2022, the Company amended the CHF-denominated intercompany loan to extend the termination date to September 2023 and as a result, the Company early terminated the cross-currency swap designated as cash flow hedge of an intercompany loan with aggregate notional amount of $50.0 million. Simultaneously, the Company entered into a cross-currency swap agreement to convert a notional amount of CHF 48.5 million equivalent to $49.1 million of this

On December 21, 2020, the Company entered into cross-currency swap agreements to convert a notional amount of $471.6 million equivalent to 420.1 million of a CHF-denominated intercompany loan into U.S. dollars. The CHF-denominated intercompany loan was the result of an intra-entity transfer of certain intellectual property rights to a subsidiary in Switzerland completed during the fourth quarter of 2020. The intercompany loan requires quarterly payments of CHF 5.8 million plus accrued interest. As a result, the aggregate notional amount of the related cross-currency swaps will decrease by a corresponding amount.

The objective of these cross-currency swaps is to reduce volatility of earnings and cash flows associated with changes in the foreign currency exchange rate. Under the terms of these contracts, which have been designated as cash flow hedges, the Company will make interest payments in Swiss Francs and receive interest in U.S. dollars. Upon the maturity of these contracts, the Company will pay the principal amount of the loans in Swiss Francs and receive U.S. dollars from the counterparties.

On September 30, 2021, in accordance with the termination date, the Company settled cross-currency swaps designated as net investment hedge with an aggregate notional amount of $52 million equivalent to 44.9 million Euros.

The Company manages its concentration of counterparty credit risk on its derivative instruments by limiting acceptable counterparties to a group of major financial institutions with investment grade credit ratings, and by actively monitoring their credit ratings and outstanding positions on an ongoing basis. Therefore, the Company considers the credit risk of the counterparties to be low. Furthermore, none of the Company’s derivative transactions are subject to collateral or other security arrangements, and none contain provisions that depend upon the Company’s credit ratings from any credit rating agency.

The Company has classified all of its derivative instruments within Level 2 of the fair value hierarchy because observable inputs are available for substantially the full term of the derivative instruments. The fair values of the interest rate swaps and cross-currency swaps were developed using a market approach based on publicly available market yield curves and the terms of the swap. The Company performs ongoing assessments of counterparty credit risk.

For the years ended December 31, 2022 and 2021, the Company recorded a gain of $11.1 million and gain of $23.8 million, respectively, in other income, net related to change in fair value related to the foreign currency rate translation of the cross-currency swaps, designated as cash flow hedges, to offset the gains or losses recognized on the intercompany loans.

For the years ended December 31, 2022 and 2021, the Company recorded gains of $8.4 million and $9.1 million, respectively, in other income, net included in the consolidated statements of operations related to the interest rate differential of the cross-currency swaps designated as cash flow hedges.

The estimated gain that is expected to be reclassified to other income, net from AOCI as of December 31, 2022, for the cross-currency swaps designated as cash flow hedges within the next twelve months is $4.5 million. As of December 31, 2022, the Company does not expect any gains or losses will be reclassified into earnings as a result of the discontinuance of these cash flow hedges because the original forecasted transaction will not occur.

During the fourth quarter of 2020, the Company entered into foreign currency forward contracts, with a notional amount of $4.2 million, to mitigate the foreign exchange risk related to certain intercompany loans denominated in Canadian Dollar ("CAD"). These contracts were settled in third quarter of 2022.

During the second quarter of 2021, the Company entered into a foreign currency swap, with a notional amount of $7.3 million, to mitigate the risk from fluctuations in foreign currency exchange rates associated with an intercompany loan denominated in JPY. In a foreign currency swap transaction, the Company agrees with another party to exchange, at specified intervals, the difference between one currency and another currency at a fixed exchange rate, generally set at inception, calculated by reference to an agreed upon notional amount. The notional amount of each currency is exchanged at the inception and termination of the currency swap by each party. The Company subsequently paid down a portion of this swap, bringing the notional amount down to $6.4 million.
