Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENT AND DERIVATIVE INSTRUMENTS	FAIR VALUE MEASUREMENT AND DERIVATIVE INSTRUMENTS ASC 820 “Fair Value Measurements and Disclosures” defines fair value, establishes a framework for measuring fair value and explains the related disclosure requirements. ASC 820 indicates, among other things, that a fair value measurement assumes that the transaction to sell an asset or transfer a liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability and defines fair value based upon an exit price model. Valuation Hierarchy. ASC 820 establishes a valuation hierarchy for disclosure of the inputs to valuation used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based on the Company’s assumptions used to measure assets and liabilities at fair value. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The Company’s cash, cash equivalents and restricted cash are highly liquid investments purchased with an original maturity of three months or less and are considered Level 1 on the fair value valuation hierarchy. The fair value of cash, cash equivalents and restricted cash approximated the carrying value at March 31, 2026 and December 31, 2025. The Senior Notes are considered Level 2 based on the fair value valuation hierarchy. Hedging Activities In the normal course of business, the Company is exposed to market risk related to interest rates, commodity prices and foreign currency exchange rate fluctuations, which may adversely affect our operating results and financial position. At times, we limit these risks through the use of derivatives such as cross-currency swaps, foreign currency forward contracts, interest rate swaps, commodity swaps and options. These hedging contracts are valued using broker quotations, or market transactions in either the listed or over-the-counter markets. As such, these derivative instruments are classified within Level 2. In accordance with our policy, derivatives are only used for hedging purposes. We do not use derivatives for trading or speculative purposes. The Company uses forward contracts to hedge forecasted foreign currency denominated sales of finished goods and future settlement of foreign currency denominated assets and liabilities. The Company may use interest rate hedge contracts on certain investing and borrowing transactions to manage its net exposure to interest rate changes and to manage its overall cost of borrowing. The Company may also use commodity forward swaps to manage its exposure to commodity price changes and to reduce its overall cost of manufacturing. The Company has also established balance sheet risk management and net investment hedging programs to protect its balance sheet against foreign currency exchange rate volatility. We conduct our business worldwide in U.S. dollars and the functional currencies of our foreign subsidiaries, including euro, Indian rupee, British pound sterling, Australian dollars, Canadian dollars, Brazilian real, Kazakhstani tenge, and several other foreign currencies. Changes in these foreign currency exchange rates could have a material adverse impact on our financial results that are reported in U.S. dollars. We are also exposed to foreign currency exchange rate risk related to our foreign subsidiaries, including intercompany loans denominated in non-functional currencies. We hedge these exposures using foreign currency swap contracts and cross-currency swaps to offset the potential income statement effects on intercompany loans denominated in non-functional currencies. These programs reduce but do not eliminate foreign currency exchange rate risk entirely. Net gains and losses related to the Company's hedging activities, except as described below, were not material for the three months ended March 31, 2026 and 2025. During 2025, in connection with the acquisitions of Frauscher and Dellner Couplers, the Company entered into foreign exchange contracts for a notional value of €1,290 million to mitigate foreign currency exposure of the purchase prices. As part of the acquisition of Frauscher in the fourth quarter of 2025, the Company utilized foreign exchange forward contracts with a notional value of €690 million. As part of the acquisition of Dellner Couplers in the first quarter of 2026, the Company utilized foreign exchange forward contracts with a notional value of €600 million. The contracts are not designated as accounting hedges under Topic 815 of ASC, and as such, the gains and losses are recorded as a component of Other income (expense), net. For the three months ended March 31, 2026, these contracts resulted in a net gain of $2 million. At March 31, 2026, the Company had a total gross notional amount of designated and non-designated derivatives of $478 million and $496 million, respectively. At December 31, 2025, the Company had a total gross notional amount of designated and non-designated derivatives of $467 million and $1.355 billion, respectively. The related assets and liabilities at both March 31, 2026 and December 31, 2025 were not significant.
