Derivative instruments we are party to include: (i) interest rate swap agreements (which are designated as cash flow hedges) and (ii) cross-currency swap agreements (which are designated as net investment hedges).

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, 2021 and December 31, 2020, we had $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 rates as specified in the interest rate swap agreements.

In July 2019, we entered into forward-starting interest rate swap agreements to limit our exposure to changes in interest rates on a portion of our floating rate indebtedness once our current interest rate swap agreements expire in March 2022. The forward-starting interest rate swap agreements have $350,000 in notional value, commence in March 2022 and expire in March 2024. Under the forward-starting interest rate swap agreements, we will receive variable rate interest payments based upon one-month LIBOR, in exchange for the payment of fixed interest rates as specified in the interest rate swap agreements.

We have designated these interest rate swap agreements, including the forward-starting interest rate swap agreements, as cash flow hedges. Unrealized gains are recognized as assets, while unrealized losses are recognized as liabilities.

In August 2019, we entered into cross-currency swap agreements to hedge the variability of exchange rate impacts between the United States dollar and the Euro. Under the terms of the cross-currency swap agreements, we notionally exchanged approximately $110,000 at an interest rate of 6.0% for approximately 99,055 Euros at a weighted average interest rate of approximately 3.65%. These cross-currency swap agreements expire in August 2023 (“August 2023 Cross-Currency Swap Agreements”).

In September 2020, we entered into cross-currency swap agreements to hedge the variability of exchange rate impacts between the United States dollar and the Euro. Under the terms of the cross-currency swap agreements, we notionally exchanged approximately $359,200 at an interest rate of 4.5% for approximately 300,000 Euros at a weighted average interest rate of approximately 3.4%. These cross-currency swap agreements expire in February 2026 (“February 2026 Cross-Currency Swap Agreements”).

We have designated these cross-currency swap agreements as a hedge of net investment against certain of our Euro denominated subsidiaries and they require an exchange of the notional amounts at maturity. These cross-currency swap agreements are marked to market at each reporting period, representing the fair values of the cross-currency swap agreements, and any changes in fair value are recognized as a component of Accumulated other comprehensive items, net. Unrealized gains are recognized as assets while unrealized losses are recognized as liabilities.

Prior to their redemption in August 2020, we designated a portion of our previously outstanding 3% Euro Senior Notes due 2025 (the “Euro Notes”) as a hedge of net investment of certain of our Euro denominated subsidiaries. From January 1, 2020 through March 31, 2020, we designated 300,000 Euros of our Euro Notes as a hedge of net investment of certain of our Euro denominated subsidiaries. As a result, we recorded foreign exchange (gains) losses related to the change in fair value of such debt due to currency translation adjustments as a component of Accumulated other comprehensive items, net.

Foreign exchange gains (losses) associated with this hedge of net investment for the three and nine months ended September 30, 2021 and 2020 are as follows:

(1)As there are no hedges of net investment outstanding during the three and nine months ended September 30, 2021, no foreign exchange gains (losses) associated with hedges of net investment have been recognized.

As of September 30, 2021, cumulative net gains of $3,256, net of tax, are recorded in Accumulated other comprehensive items, net associated with this net investment hedge.
