Equity securities with readily determinable fair values - Balances of equity securities are recorded within other assets, with any changes in fair value recorded within other (income) expense, net. The fair values of equity securities are based upon quoted market prices, which are considered Level 1 inputs.

Long-term borrowings - The estimated fair values of these borrowings are based on recent trades, as reported by a third-party pricing service. Due to the infrequency of trades, these inputs are considered to be Level 2 inputs.

Derivative instruments - The Company's interest rate caps, interest rate swaps and cross-currency swaps are valued using broker quotations, or market transactions in either the listed or over-the-counter markets. As such, these derivative instruments are included in the Level 2 hierarchy.

The fair value of contingent consideration associated with an acquisition completed in the current year is valued at each balance sheet date, until amounts become payable, with adjustments recorded in other (income) expense within other operating charges in the consolidated statements of operations. During the year ended December 31, 2021, in conjunction with the acquisition in China described in Note 3, we recorded fair value of contingent consideration of $7.8 million, including $0.5 million of accretion for the passage of time and currency translation. The contingent consideration was valued using a probability-weighted expected payment method. The analysis considered the timing of expected future cash flows and the probability of whether key elements of the contingent event are completed. Due to the significant unobservable inputs used in the valuations, these liabilities are categorized within Level 3 of the fair value hierarchy.

We selectively use derivative instruments to reduce market risk associated with changes in foreign currency exchange rates and interest rates. The use of derivatives is intended for hedging purposes only, and we do not enter into derivative instruments for speculative purposes. A description of each type of derivative used to manage risk is included in the following paragraphs.

Certain derivative instruments in use are contingent upon changes in LIBOR, which is the subject of recent reform and will cease being published in June 2023. The derivative instruments under LIBOR terms that we are currently party to will either mature before June 2023 or the agreements contain transitional language to a different reference rate.

During the year ended December 31, 2017, we entered into four 1.5% interest rate caps with aggregate notional amounts totaling $850.0 million to hedge the variable interest rate exposures on our 2024 Dollar Term Loans. The final interest rate cap entered into during 2017, comprising $250.0 million of notional value, expired December 31, 2021 and had a deferred premium of $8.1 million at inception. All deferred premiums were paid quarterly over the term of the respective interest rate caps. These interest rate caps were marked to market at each reporting date and any unrealized gains or losses were included in AOCI and reclassified to interest expense in the same period or periods during which the hedged transactions affected earnings.

During the three months ended June 30, 2018, we entered into three interest rate swaps with aggregate notional amounts totaling $475.0 million to hedge interest rate exposures related to variable rate borrowings under the 2024 Dollar Term Loans. Under the terms of the interest rate swap agreements, the Company is required to pay the counter-parties a stream of fixed interest payments at a rate of 2.72% and in turn, receives variable interest payments based on 3-month LIBOR from the counter-parties. The interest rate swaps are designated as cash flow hedges and expire on March 31, 2023. These interest rate swaps are marked to market at each reporting date and any unrealized gains or losses are included in AOCI and reclassified to interest expense in the same period or periods during which the hedged transactions affect earnings.

During the three months ended March 31, 2019, we entered into two interest rate swaps with aggregate notional amounts totaling $500.0 million, effective December 31, 2019, to hedge interest rate exposure associated with the 2024 Dollar Term Loans. Under the terms of the interest rate swap agreements, the Company is required to pay the counter-parties a stream of fixed interest payments at a rate of 2.59% and in turn, receives variable interest payments based on 3-month LIBOR from the counter-parties. The interest rate swaps are designated as cash flow hedges and expire on December 31, 2022. These interest rate swaps are marked to market at each reporting date and any unrealized gains or losses are included in AOCI and reclassified to interest expense in the same period or periods during which the hedged transactions affect earnings.

During the three months ended March 31, 2020, we entered into two interest rate swaps with aggregate notional amounts totaling $400.0 million to hedge interest rate exposures associated with the 2024 Dollar Term Loans. Under the terms of the interest rate swap agreements, the Company is required to pay the counter-parties a stream of fixed interest payments at rates of 1.61% and 1.18% on $200.0 million of notional value for each instrument, and in turn, receives variable interest payments based on 3-month LIBOR from the counter-parties. The interest rate swaps are designated as cash flow hedges and expire on December 31, 2022. These interest rate swaps are marked to market at each reporting date and any unrealized gains or losses are included in AOCI and reclassified to interest expense in the same period or periods during which the hedged transactions affect earnings.

During the three months ended December 31, 2018, we notionally exchanged $475.0 million at a weighted average interest rate of 4.47% for €416.6 million at a weighted average interest rate of 1.44%. The cross-currency swaps are designated as net investment hedges and expire on March 31, 2023. These cross-currency swaps are marked to market at each reporting date and any unrealized gains or losses are included in unrealized currency translation adjustments, within AOCI.

During the three months ended December 31, 2020, in connection with the issuance of the 2029 Dollar Senior Notes, we entered into two fixed-for-fixed cross currency swaps with aggregate notional amounts totaling €335.0 million to hedge the variability of exchange rate impacts between the U.S. Dollar and Euro. Under the terms of the cross-currency swap agreements, the Company notionally exchanged $396.3 million at a weighted average interest rate of 3.375% for €335.0 million at a weighted average interest rate of 2.15%. The cross-currency swaps are designated as net investment hedges and expire on February 15, 2029. These cross-currency swaps are marked to market at each reporting date and any unrealized gains or losses are included in unrealized currency translation adjustments, within AOCI.

During the year ended December 31, 2020, we designated foreign currency forward contracts with a notional value of $8.3 million as cash flow hedges of the Company's exposure to variability in exchange rates on forecasted purchases of inventory denominated in foreign currencies. These forward currency contracts were marked to market at each reporting date and any unrealized gains or losses were included in AOCI and reclassified to cost of goods sold in the same period or periods during which the hedged transactions affect earnings. These foreign currency forward contracts expired during the year ended December 31, 2021.

We periodically enter into foreign currency forward and option contracts to reduce market risk and hedge our balance sheet exposures and cash flows for subsidiaries with exposures denominated in currencies different from the functional currency of the relevant subsidiary. These contracts have not been designated as hedges and all gains and losses are marked to market through other (income) expense, net in the consolidated statement of operations.

During July 2021, we entered into two foreign currency forward contracts with a total notional value of £259.1 million to hedge the variability in exchange rates between the execution date of the agreement to purchase U-POL and the closing of the transaction. The contracts were settled in September 2021, and we realized a loss of $0.6 million within other (income) expense, net in the consolidated statement of operations.
