The Company uses forwards, swaps and other derivative contracts to reduce the effects of fluctuations in foreign exchange rates on known foreign currency exposures. Gains and losses on the derivative instruments are intended to offset gains and losses on the hedged transaction in an effort to reduce exposure to fluctuations in foreign exchange rates. The principal currencies hedged by the Company include the Mexican peso, various European currencies, the Chinese renminbi, the Philippine peso and the Japanese yen.

The Company uses cross-currency interest rate swaps which are designated as net investment hedges of the foreign currency rate exposure of its investment in certain Euro-denominated subsidiaries.

GAAP provides that fair value is an exit price, defined as a market-based measurement that represents the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value measurements are based on one or more of the following three valuation techniques:


Market:						This approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities.

Income:						This approach uses valuation techniques to convert future amounts to a single present value amount based on current market expectations.

Cost:						This approach is based on the amount that would be required to replace the service capacity of an asset (replacement cost).


Level 1:						Observable inputs, such as quoted market prices in active markets for identical assets or liabilities that are accessible at the measurement date.

Level 2:						Inputs, other than quoted market prices included in Level 1, that are observable either directly or indirectly for the asset or liability.

Level 3:						Unobservable inputs that reflect the entity's own assumptions about the exit price of the asset or liability. Unobservable inputs may be used if there is little or no market data for the asset or liability at the measurement date.

Fair value measurements and the related valuation techniques and fair value hierarchy level for the Company's assets and liabilities measured at fair value on a recurring basis as of December 31, 2022 and 2021, are shown below (in millions):


	December 31, 2022
	Frequency	Asset (Liability)		Valuation Technique	Level 1		Level 2		Level 3
Foreign currency contracts, net	Recurring	$	62.9	Market / Income	$	—	$	62.9	$	—
Net investment hedges	Recurring	4.8		Market / Income	—		4.8		—
Marketable equity securities	Recurring	57.2		Market	57.2		—		—

The Company determines the fair value of its derivative contracts using quoted market prices to calculate the forward values and then discounts such forward values to the present value. The discount rates used are based on quoted bank deposit or swap interest rates. If a derivative contract is in a net liability position, the Company adjusts these discount rates, if required, by an estimate of the credit spread that would be applied by market participants purchasing these contracts from the Company's counterparties. If an estimate of the credit spread is required, the Company uses significant assumptions and factors other than quoted market rates, which would result in the classification of its derivative liabilities within Level 3 of the fair value hierarchy. As of December 31, 2022 and 2021, there were no derivative contracts that were classified within Level 3 of the fair value hierarchy. In addition, there were no transfers in or out of Level 3 of the fair value hierarchy during 2022 and 2021.

The Company measures certain assets and liabilities at fair value on a non-recurring basis, which are not included in the table above. As these non-recurring fair value measurements are generally determined using unobservable inputs, these fair value measurements are classified within Level 3 of the fair value hierarchy.

In 2022 and 2020, the Company completed quantitative goodwill impairment analyses for selected reporting units (Note 3, "Summary of Significant Accounting Policies — Impairment of Goodwill"). The Level 3 fair value estimate of the reporting units was based on a third-party valuation and/or management's estimates, using a combination of the discounted cash flow method and/or guideline public company method.

In 2022, as a result of the acquisition of Kongsberg ICS (Note 4, "Acquisition of Kongsberg ICS"), Level 3 fair value estimates related to property, plant and equipment of $124.1 million, right-of-use assets of $34.1 million and developed technology intangible assets of $11.1 million are recorded in the accompanying consolidated balance sheet as of December 31, 2022. Fair value estimates of property, plant and equipment were based on independent appraisals, giving consideration to the highest and best use of the assets. Key assumptions used in the appraisals were based on a combination of market and cost approaches, as appropriate. Fair value estimates of right-of-use assets were based on a market approach. Fair value estimates of developed technology intangible asset were based on a relief from royalty approach.

In 2022 and 2021, the Company completed impairment assessments related to certain of its intangible assets resulting from changes in the intended uses of such assets and recorded impairment charges of $8.9 million and $8.5 million, respectively. The fair value estimate of the related asset group was based on management's estimates using a discounted cash flow method (Note 3, "Summary of Significant Accounting Policies — Impairment of Long-Lived Assets").

In 2022, the Company completed impairment assessments related to substantially all of its operating assets in Russia and recorded charges of $19.4 million related to impairments of inventory, property, plant and equipment and right-of-use assets.
