Derivatives and Hedging

3 Months Ended

Mar. 31, 2024

The valuation of our derivative contracts used to manage their respective risks is described below:

•Foreign Currency – The fair value of any foreign currency option derivative is based upon valuation models applied to current market information such as strike price, spot rate, maturity date and volatility, and by reference to market values resulting from an over-the-counter market or obtaining market data for similar instruments with similar characteristics.

•Commodity – The fair value of copper derivatives is computed using a combination of intrinsic and time value valuation models, which are collectively a function of five primary variables: price of the underlying instrument, time to expiration, strike price, interest rate and volatility. The intrinsic valuation model reflects the difference between the strike price of the underlying copper derivative instrument and the current prevailing copper prices in an over-the-counter market at period end. The time value valuation model incorporates changes in the price of the underlying copper derivative instrument, the time value of money, the underlying copper derivative instrument’s strike price and the remaining time to the underlying copper derivative instrument’s expiration date from the period end date.

As of March 31, 2024, we did not have any derivative contracts that qualified for hedge accounting treatment.

Foreign Currency

During the three months ended March 31, 2024, we entered into U.S. dollar, euro, Korean won, and Japanese yen forward contracts. We entered into these foreign currency forward contracts to mitigate certain global transactional exposures. These contracts do not qualify for hedge accounting treatment. As a result, any fair value adjustments required on these contracts are recorded in “Other income (expense), net” in our condensed consolidated statements of operations in the period in which the adjustment occurred.

As of March 31, 2024, the notional values of the remaining foreign currency forward contracts were as follows:


Notional Values of Foreign Currency Derivatives
USD/CNH	$	20,700,000
EUR/USD	€	14,700,000
KRW/USD	₩	5,372,800,000
JPY/EUR	¥	250,000,000

Commodity

As of March 31, 2024, we had 12 outstanding contracts to hedge exposure related to the purchase of copper in our AES operating segment. These contracts are held with financial institutions and are intended to offset rising copper prices and do not qualify for hedge accounting treatment. As a result, any fair value adjustments required on these contracts are recorded in “Other income (expense), net” in our condensed consolidated statements of operations in the period in which the adjustment occurred.

As of March 31, 2024, the volume of our copper contracts outstanding was as follows:


Volume of Copper Derivatives
April 2024 - June 2024			69 metric tons per month
July 2024 - September 2024			69 metric tons per month
October 2024 - December 2024			69 metric tons per month
January 2025 - March 2025			69 metric tons per month

The accounting guidance for fair value measurements establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value:

•Level 1 – Quoted prices in active markets for identical assets or liabilities.

•Level 2 – Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

•Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The fair values of derivative instruments measured at fair value on a recurring basis, categorized by contract type and level of inputs used in the valuation, were as follows:


	Derivative Instruments at Fair Value as of March 31, 2024
(Dollars in millions)	Level 1		Level 2		Level 3		Total(1)
Foreign currency contracts	$	—	$	(0.1)	$	—	$	(0.1)
Copper derivative contracts	$	—	$	0.5	$	—	$	0.5


	Derivative Instruments at Fair Value as of December 31, 2023
(Dollars in millions)	Level 1		Level 2		Level 3		Total(1)
Foreign currency contracts	$	—	$	(0.2)	$	—	$	(0.2)
Copper derivative contracts	$	—	$	0.4	$	—	$	0.4
