| Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
| DESCRIPTION OF BUSINESS | NOTE 1. DESCRIPTION OF BUSINESS Olin Corporation (Olin, the Company, we or our) is a Virginia corporation, incorporated in 1892, having its principal executive offices in Clayton, MO. We are a leading vertically integrated global manufacturer and distributor of chemical products and a leading U.S. manufacturer of ammunition. Our operations are concentrated in three business segments: Chlor Alkali Products and Vinyls, Epoxy and Winchester. All of our business segments are capital-intensive manufacturing businesses. The Chlor Alkali Products and Vinyls segment manufactures and sells chlorine and caustic soda, ethylene dichloride and vinyl chloride monomer, methyl chloride, methylene chloride, chloroform, carbon tetrachloride, perchloroethylene, hydrochloric acid, hydrogen, bleach products and potassium hydroxide. The Epoxy segment produces and sells a full range of epoxy materials and precursors, including aromatics (acetone and phenol), allyl chloride, epichlorohydrin, liquid epoxy resins, solid epoxy resins and formulated solutions products such as converted epoxy resins and additives. The Winchester segment produces and sells sporting ammunition, reloading components, small caliber military ammunition and components, industrial cartridges and clay targets. Basis of Presentation We have prepared the condensed financial statements included herein, without audit, pursuant to the rules and regulations of the United States (U.S.) Securities and Exchange Commission (SEC). The preparation of the financial statements requires estimates and assumptions that affect amounts reported and disclosed in the financial statements and related notes. In our opinion, these financial statements reflect all adjustments (consisting only of normal accruals), which are necessary to present fairly the results for interim periods. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations; however, we believe that the disclosures are appropriate. We recommend that you read these condensed financial statements in conjunction with the financial statements, accounting policies and the notes thereto and Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the year ended December 31, 2024.

| Accounting Standards Update and Change in Accounting Principle [Abstract] | |
| RECENT ACCOUNTING PRONOUNCEMENTS | NOTE 2. RECENT ACCOUNTING PRONOUNCEMENTS In November 2024, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which expands the disclosure requirements in the notes to the financial statements on certain costs and expenses on an interim and annual basis. The new requirements are effective for the Company’s annual reporting periods beginning after December 15, 2026 and interim periods beginning after December 15, 2027, with the option to early adopt at any time before the effective date. ASU 2024-03 requires adoption on a prospective basis, with the option for retrospective application. While the ASU implements further disclosure requirements, it does not change how an entity calculates and/or records its expenses, and it will have no impact on the Company’s consolidated financial statements. We are currently evaluating the impact of the standard on our disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which includes amendments that further enhance income tax disclosures, primarily through standardization and disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. The amendments are effective for annual periods beginning after December 15, 2024, with the option to early adopt at any time before the effective date. ASU 2023-09 allows for adoption on a prospective or retrospective basis. We will adopt this standard beginning with our fiscal year ending December 31, 2025. We are currently evaluating the impact of the standard on our consolidated financial statements and disclosures.

| DEBT | NOTE 10. DEBT Long-term loans, notes and other financing obligations, consisted of the following:
Senior Notes and Senior Credit Facilities On March 14, 2025, Olin issued $600.0 million aggregate principal amount of 6.625% senior notes due April 1, 2033 (2033 Notes), in a private offering exempt from the registration requirements of the Securities Act of 1933, as amended. Interest on the 2033 Notes began accruing from March 14, 2025 and is paid semi-annually beginning on October 1, 2025, and every six months thereafter. On March 14, 2025, Olin entered into a $1,850.0 million senior credit facility (2025 Senior Credit Facility), which increased the borrowing limit of our then-existing $1,550.0 million senior credit facility (2022 Senior Credit Facility) by $300.0 million and extended the maturity date from October 11, 2027 to March 14, 2030. The 2025 Senior Credit Facility includes a term loan facility with aggregate commitments of $650.0 million (2025 Term Loan Facility) and a revolving credit facility with aggregate commitments of $1,200.0 million (2025 Revolving Credit Facility). The 2025 Term Loan Facility replaced Olin’s then-existing $350.0 million term loan facility (2022 Term Loan Facility, and collectively with the new 2025 Term Loan Facility, the Term Loan Facilities). The 2025 Term Loan Facility requires principal amortization payments beginning on June 30, 2025 at a rate of 0.625% per quarter through March 31, 2027, increasing to 1.250% per quarter thereafter, until maturity, and was fully drawn on the closing date. The 2025 Revolving Credit Facility replaced Olin’s then-existing $1,200.0 million revolving credit facility (2022 Revolving Credit Facility, and collectively with the new 2025 Revolving Credit Facility, the Revolving Credit Facilities). The 2025 Revolving Credit Facility includes a $100.0 million letter of credit subfacility. At June 30, 2025, we had $1,164.6 million available under our 2025 Revolving Credit Facility because we had $35.0 million borrowed under the facility and issued $0.4 million of letters of credit. Proceeds from the 2033 Notes, together with borrowings under the 2025 Senior Credit Facility, were used to redeem the $108.6 million 2025 Notes, redeem the $500.0 million 2027 Notes, refinance the then-existing 2022 Senior Credit Facility, comprised of $505.0 million of borrowings under the 2022 Revolving Credit Facility and $332.5 million of borrowings under the 2022 Term Loan Facility, and pay related fees and expenses. We were in compliance with all covenants and restrictions under all our outstanding debt agreements as of June 30, 2025, and no event of default had occurred under any of our outstanding debt agreements that would permit the acceleration of the debt if not cured. In the future, our ability to generate sufficient operating cash flows, among other factors, will determine the amounts available to be borrowed under these facilities. As a result of our restrictive covenant related to the net leverage ratio, the maximum additional borrowings available to us could be limited in the future. The limitation, if an amendment or waiver from our lenders is not obtained, could restrict our ability to borrow the maximum amounts available under the 2025 Senior Credit Facility and the 2024 Receivables Financing Agreement (defined below). As of June 30, 2025, there were no covenants or other restrictions that limited our ability to borrow. Receivables Financing Agreements On November 20, 2024, we entered into a $500.0 million receivables financing agreement (2024 Receivables Financing Agreement), which increased the borrowing limit of our then-existing $425.0 million receivables financing agreement (2022 Receivables Financing Agreement) by $75.0 million and extended the maturity date from October 14, 2025 to November 19, 2027 (collectively, the Receivables Financing Agreements). Under the Receivables Financing Agreements, our eligible trade receivables are used for collateralized borrowings and continue to be serviced by us. In addition, the Receivables Financing Agreements incorporate the net leverage ratio covenant that is contained in the 2025 Senior Credit Facility. As of June 30, 2025, December 31, 2024 and June 30, 2024, we had $465.0 million, $475.0 million and $298.8 million, respectively, drawn under the Receivables Financing Agreements. As of June 30, 2025, $609.3 million of our trade receivables were pledged as collateral and we had $35.0 million of additional borrowing capacity under the 2024 Receivables Financing Agreement. As part of the 2024 Receivables Financing Agreement, we terminated our then-existing trade accounts receivable factoring arrangements (AR Facilities), under which certain of our domestic and international subsidiaries could sell their accounts receivable. These receivables had qualified for sales treatment under ASC 860 “Transfers and Servicing” and, accordingly, the proceeds were included in net cash provided by operating activities in the consolidated statements of cash flows. Financing Cash Flows During the six months ended June 30, 2025 and 2024, activity of our outstanding debt included:
Other Financing Interest expense for the six months ended June 30, 2025 included $3.3 million for the write-off of unamortized deferred debt issuance costs and costs associated with our first quarter financing transactions, including the 2025 Senior Credit Facility, early redemption of the 2025 Notes and the 2027 Notes, and issuance of the 2033 Notes. For the six months ended June 30, 2025, we paid debt issuance costs of $12.0 million associated with the 2033 Notes and the 2025 Senior Credit Facility.

| PENSION PLANS AND RETIREMENT BENEFITS | NOTE 11. PENSION PLANS AND RETIREMENT BENEFITS We sponsor domestic and foreign defined benefit pension plans for eligible employees and retirees. Most of our domestic employees participate in defined contribution plans. However, a portion of our bargaining hourly employees continue to participate in our domestic qualified defined benefit pension plans under a flat-benefit formula. Our funding policy for the qualified defined benefit pension plans is consistent with the requirements of federal laws and regulations. Our foreign subsidiaries maintain pension and other benefit plans, which are consistent with local statutory practices. Our domestic qualified defined benefit pension plan provides that if, within three years following a change of control of Olin, any corporate action is taken or filing made in contemplation of, among other things, a plan termination or merger or other transfer of assets or liabilities of the plan, and such termination, merger, or transfer thereafter takes place, plan benefits would automatically be increased for affected participants (and retired participants) to absorb any plan surplus (subject to applicable collective bargaining requirements). We also provide certain postretirement healthcare (medical) and life insurance benefits for eligible active and retired domestic employees. The healthcare plans are contributory with participants’ contributions adjusted annually based on medical rates of inflation and plan experience.
We made cash contributions to our international qualified defined benefit pension plans of $0.6 million and $0.8 million for the six months ended June 30, 2025 and 2024, respectively.

| INCOME TAXES | NOTE 12. INCOME TAXES The effective tax rate for the three months ended June 30, 2025 included a net $3.3 million tax benefit, primarily associated with U.S. federal investment tax credits and a release of valuation allowances on domestic state net operating losses and tax credits, partially offset by an expense from prior year tax positions and a change in tax contingencies. Excluding these items, the effective tax rate for the three months ended June 30, 2025 of 10.3% was lower than the 21.0% U.S. federal statutory rate primarily due to state income tax, favorable permanent salt depletion deductions, non-taxable exchange rate results and a favorable foreign rate differential, partially offset by foreign income inclusions. The effective tax rate for the three months ended June 30, 2024 included a net $0.6 million tax benefit, primarily associated with stock-based compensation and U.S. federal tax credits purchased at a discount, partially offset by an expense from prior year tax positions and a change in tax contingencies. Excluding these items, the effective tax rate for the three months ended June 30, 2024 of 25.8% was higher than the 21.0% U.S. federal statutory rate primarily due to state income tax and foreign income inclusions, partially offset by favorable permanent salt depletion deductions. The effective tax rate for the six months ended June 30, 2025 included a net $2.9 million tax benefit primarily associated with U.S. federal investment tax credits and a release of valuation allowances on domestic state net operating losses and tax credits, partially offset by an expense from prior year tax positions and a change in tax contingencies. Excluding these items, the effective tax rate for the six months ended June 30, 2025 of 4.3% was lower than the 21.0% U.S. federal statutory rate primarily due to state income tax, favorable permanent salt depletion deductions, non-taxable exchange rate results and a favorable foreign rate differential, partially offset by foreign income inclusions. The effective tax rate for the six months ended June 30, 2024 included a net $3.3 million tax benefit, primarily associated with stock-based compensation and U.S. federal tax credits purchased at a discount, partially offset by an expense from prior year tax positions and a change in tax contingencies. Excluding these items, the effective tax rate for the six months ended June 30, 2024 of 25.6% was higher than the 21.0% U.S. federal statutory rate primarily due to state income tax and foreign income inclusions, partially offset by favorable permanent salt depletion deductions. In August 2022, the Inflation Reduction Act (the IRA) was enacted and provides various beneficial credits for energy efficient related manufacturing, transportation and fuels, hydrogen/carbon recapture and renewable energy, which we are evaluating in regard to planned projects. In the second quarter of 2025, Olin realized $22.0 million of investment tax credits via its Hidrogenii joint venture interest and recorded a tax benefit of $2.6 million. On July 4, 2025, the One Big Beautiful Bill Act (OBBBA) was enacted in the U.S. This act introduces significant changes to tax law and other areas affecting company operations, including items such as extensions of Tax Cuts and Jobs Act provisions, changes to business interest deductions, modifications to depreciation deductions and impacts on energy tax credits. While the effects of these tax law changes will not be reflected in interim or annual provisions for the period ended June 30, 2025, the Company is evaluating the potential impact of the OBBBA on its financial position, results of operations, and cash flows for future periods. Specific potential impacts that are being assessed include effects on future tax expense, cash flows from operations due to new deductions, or potential impacts on investment decisions. Further details on the impact of this legislation will be provided as the evaluation progresses. As of June 30, 2025, we had $22.3 million of gross unrecognized tax benefits, which would have impacted the effective tax rate, if recognized. The amounts of unrecognized tax benefits were as follows:
As of June 30, 2025, we believe it is reasonably possible that our total amount of unrecognized tax benefits will decrease by approximately $9.5 million over the next twelve months. The anticipated reduction primarily relates to expected settlements with tax authorities and the expiration of federal, state and foreign statutes of limitation. We operate globally and file income tax returns in numerous jurisdictions. Our tax returns are subject to examination by various federal, state and local tax authorities. Additionally, examinations are ongoing in various states and foreign jurisdictions. We believe we have adequately provided for all tax positions; however, amounts asserted by taxing authorities could be greater than our accrued position. For our primary tax jurisdictions, the tax years that remain subject to examination are as follows:

| Share-Based Payment Arrangement [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| STOCK-BASED COMPENSATION | NOTE 14. STOCK-BASED COMPENSATION Stock-based compensation granted includes stock options, performance share awards, restricted stock awards and deferred directors’ compensation. Stock-based compensation expense was as follows:
Performance Shares Performance share awards are denominated in shares of our stock and are paid half in cash and half in stock. Payouts for performance share awards are based on two criteria: (1) 50% of the award is based on Olin’s total shareholder returns (TSR) over the applicable three-year performance cycle in relation to the TSR over the same period among a portfolio of public companies which are selected in concert with outside compensation consultants and (2) 50% of the award is based on Olin’s net income over the applicable three-year performance cycle in relation to the net income goal for such period as set by the Compensation Committee of Olin’s Board of Directors. The expense associated with performance shares is recorded based on our estimate of our performance relative to the respective target. If an employee leaves the Company before the end of the performance cycle, the performance shares may be prorated based on the number of months of the performance cycle worked and are settled in cash instead of half in cash and half in stock when the three-year performance cycle is completed. The fair value of each performance share award based on net income was estimated on the date of grant, using the current stock price. The fair value of each performance share award based on TSR was estimated on the date of grant, using a Monte Carlo simulation model with the following weighted average assumptions:
The risk-free interest rate was based on zero coupon U.S. Treasury securities rates for the expected life of the performance share awards. The expected volatility of Olin common stock and peer companies was based on historical stock price movements, as we believe that historical experience is the best available indicator of the expected volatility. The average correlation coefficient of peer companies was determined based on historical trends of Olin’s common stock price compared to the peer companies. Expected life of the performance share award grant was based on historical exercise and cancellation patterns, as we believe that historical experience is the best estimate of future exercise patterns. Restricted Stock Units During the six months ended June 30, 2025 and 2024, Olin granted restricted stock units of 452,863 and 219,500, respectively, at a weighted average grant date fair value per share of $26.96 and $56.99, respectively. The fair value of each restricted stock unit was estimated on the date of grant using the current stock price. The awards typically vest ratably, on an annual basis, over three years, but not less than one year. Stock Options During the six months ended June 30, 2025, Olin granted no stock options. During the six months ended June 30, 2024, Olin granted stock options of 601,157 at a weighted-average grant date fair value per option of $24.79 and a weighted-average exercise price of $53.43. The fair value of each stock option granted, which typically vests ratably over three years, but not less than one year, was estimated on the date of grant, using the Black-Scholes option-pricing model.

| SEGMENT INFORMATION | NOTE 16. SEGMENT INFORMATION The chief operating decision maker (CODM) is the individual, or group of individuals, who assess financial performance and determines resource allocation. Management has identified our Chief Executive Officer (CEO) as the CODM. In arriving at this conclusion, we considered that the individual who receives the relevant financial information, which is primarily provided in the form of segment operations reviews, is ultimately our CEO. Further, our CEO assesses the reasonableness of resource allocation, primarily in the form of capital allocation and budgetary analysis, and reviews segment results and resource allocation summaries prepared by segment management, consistent with their view of the business as a whole. We define segment results as income (loss) before interest expense, interest income, other operating income (expense), non-operating pension income, other income and income taxes, and includes the results of non-consolidated affiliates in segment results consistent with management’s monitoring of the operating segments. We have three operating segments: Chlor Alkali Products and Vinyls, Epoxy, and Winchester. The three operating segments reflect the organization used by our management for purposes of allocating resources and assessing performance, and represents our reportable segments. Chlorine and caustic soda used in our Epoxy segment is transferred at cost from the Chlor Alkali Products and Vinyls segment. Cost of goods sold at Corporate is primarily attributed to environmental expense. Other segment items for each reportable segment includes selling, general and administrative expenses and earnings (losses) from non-consolidated affiliates. Segment assets include only those assets which are directly identifiable to an operating segment. Assets in the corporate/other segment primarily include cash and cash equivalents, deferred taxes and other assets. Sales are attributed to geographic areas based on the customer location.
(1) For the three months ended June 30, 2025 and 2024, revenue recognized over time represented $94.4 million and $37.8 million, respectively, and for the six months ended June 30, 2025 and 2024, revenue recognized over time represented $152.9 million and $57.6 million, respectively, associated with governmental contracts within our Winchester business.

| Environmental Remediation Obligations [Abstract] | |
| ENVIRONMENTAL | NOTE 17. ENVIRONMENTAL We are party to various government and private environmental actions associated with past manufacturing facilities and former waste disposal sites. The condensed balance sheets included reserves for future environmental expenditures to investigate and remediate known sites amounting to $155.2 million, $156.5 million and $155.3 million at June 30, 2025, December 31, 2024 and June 30, 2024, respectively, of which $125.2 million, $126.5 million and $123.3 million, respectively, were classified as other noncurrent liabilities. Environmental provisions charged to income, which are included in costs of goods sold, were $4.8 million and $6.4 million for the three months ended June 30, 2025 and 2024, respectively, and $9.8 million and $12.2 million for the six months ended June 30, 2025 and 2024, respectively. Environmental exposures are difficult to assess for numerous reasons, including the identification of new sites, developments at sites resulting from investigatory studies, advances in technology, changes in environmental laws and regulations and their application, changes in regulatory authorities, the scarcity of reliable data pertaining to identified sites, the difficulty in assessing the involvement and financial capability of other Potentially Responsible Parties (PRPs), our ability to obtain contributions from other parties and the lengthy time periods over which site remediation occurs. It is possible that some of these matters (the outcomes of which are subject to various uncertainties) may be resolved unfavorably to us, which could materially adversely affect our financial position, cash flows or results of operations.

| Commitments and Contingencies Disclosure [Abstract] | |
| COMMITMENTS AND CONTINGENCIES | NOTE 18. COMMITMENTS AND CONTINGENCIES We, and our subsidiaries, are defendants in various legal actions (including proceedings based on alleged exposures to asbestos) incidental to our past and current business activities. As of June 30, 2025, December 31, 2024 and June 30, 2024, our condensed balance sheets included accrued liabilities for these other legal actions of $18.8 million, $19.7 million and $12.5 million, respectively. These liabilities do not include costs associated with legal representation. Based on our analysis, and considering the inherent uncertainties associated with litigation, we do not believe that it is reasonably possible that these legal actions will materially adversely affect our financial position, cash flows or results of operations. During the ordinary course of our business, contingencies arise resulting from an existing condition, situation or set of circumstances involving an uncertainty as to the realization of a possible gain contingency. In certain instances, such as environmental projects, we are responsible for managing the cleanup and remediation of an environmental site. There exists the possibility of recovering a portion of these costs from other parties. We account for gain contingencies in accordance with the provisions of ASC 450 “Contingencies” and, therefore, do not record gain contingencies and recognize income until it is earned and realizable.

| DERIVATIVE FINANCIAL INSTRUMENTS | NOTE 19. DERIVATIVE FINANCIAL INSTRUMENTS We are exposed to market risk in the normal course of our business operations due to our purchases of certain commodities, our ongoing investing and financing activities and our operations that use foreign currencies. The risk of loss can be assessed from the perspective of adverse changes in fair values, cash flows and future earnings. We have established policies and procedures governing our management of market risks and the use of financial instruments to manage exposure to such risks. ASC 815 “Derivatives and Hedging” (ASC 815) requires an entity to recognize all derivatives as either assets or liabilities in the condensed balance sheets and measure those instruments at fair value. In accordance with ASC 815, we designate derivative contracts as cash flow hedges of forecasted purchases of commodities and forecasted interest payments related to variable-rate borrowings and designate certain interest rate swaps as fair value hedges of fixed-rate borrowings. We do not enter into any derivative instruments for trading or speculative purposes. Energy costs, including electricity and natural gas, and certain raw materials used in our production processes are subject to price volatility. Depending on market conditions, we may enter into futures contracts, forward contracts, commodity swaps and put and call option contracts in order to reduce the impact of commodity price fluctuations. The majority of our commodity derivatives expire within one year. We actively manage currency exposures that are associated with net monetary asset positions, currency purchases and sales commitments denominated in foreign currencies and foreign currency denominated assets and liabilities created in the normal course of business. We enter into forward sales and purchase contracts to manage currency risk to offset our net exposures, by currency, related to the foreign currency denominated monetary assets and liabilities of our operations. All of the currency derivatives expire within one year and are for U.S. dollar (USD) equivalents. The counterparties to the forward contracts are large financial institutions; however, the risk of loss to us in the event of nonperformance by a counterparty could be significant to our financial position, cash flows or results of operations. We had the following notional amounts of outstanding forward contracts to buy and sell foreign currency:
Cash Flow Hedges For derivative instruments that are designated and qualify as a cash flow hedge, the change in fair value of the derivative is recognized as a component of other comprehensive income (loss) until the hedged item is recognized in earnings. We had the following notional amounts of outstanding commodity contracts that were entered into to hedge forecasted purchases:
As of June 30, 2025, the counterparties to these commodity contracts were Wells Fargo Bank, N.A., Citibank, N.A., JPMorgan Chase Bank, National Association, Toronto Dominion Bank and Bank of America Corporation, all of which are major financial institutions. We use cash flow hedges for certain raw material and energy costs such as copper, zinc, ethane, electricity and natural gas to provide a measure of stability in managing our exposure to price fluctuations associated with forecasted purchases of raw materials and energy used in our manufacturing process. At June 30, 2025, we had open derivative contract positions through 2028. If all open futures contracts had been settled on June 30, 2025, we would have recognized a pretax gain of $10.2 million. If commodity prices were to remain at June 30, 2025 levels, approximately $5.7 million of deferred gains, net of tax, would be reclassified into earnings during the next twelve months. The actual effect on earnings will be dependent on actual commodity prices when the forecasted transactions occur. Fair Value Hedges We use interest rate swaps as a means of managing interest expense and floating interest rate exposure to optimal levels. For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in current earnings. We include the gain or loss on the hedged items (fixed-rate borrowings) in the same line item, interest expense, as the offsetting loss or gain on the related interest rate swaps. There were no outstanding interest rate swaps at June 30, 2025, December 31, 2024 and June 30, 2024. Financial Statement Impacts We present our derivative assets and liabilities in our condensed balance sheets on a net basis whenever we have a legally enforceable master netting agreement with the counterparty to our derivative contracts. We use these agreements to manage and substantially reduce our potential counterparty credit risk. The following table summarizes the location and fair value of the derivative instruments on our condensed balance sheets:
(1) Does not include the impact of cash collateral received from or provided to counterparties, if any. The following table summarizes the effects of derivative instruments on our condensed statements of operations:
Credit Risk and Collateral By using derivative instruments, we are exposed to credit and market risk. If a counterparty fails to fulfill its performance obligations under a derivative contract, our credit risk will equal the fair value gain in a derivative. Generally, when the fair value of a derivative contract is positive, this indicates that the counterparty owes us, thus creating a repayment risk for us. When the fair value of a derivative contract is negative, we owe the counterparty and, therefore, assume no repayment risk. We minimize the credit (or repayment) risk in derivative instruments by entering into transactions with high-quality counterparties. We monitor our positions and the credit ratings of our counterparties, and we do not anticipate non-performance by the counterparties. Based on the agreements with our various counterparties, cash collateral is required to be provided when the net fair value of the derivatives, with the counterparty, exceeds a specific threshold. If the threshold is exceeded, cash is either provided by the counterparty to us if the value of the derivatives is our asset, or cash is provided by us to the counterparty if the value of the derivatives is our liability. As of June 30, 2025, December 31, 2024 and June 30, 2024, this threshold was not exceeded. In all instances where we are party to a master netting agreement, we offset the receivable or payable recognized upon payment of cash collateral against the fair value amounts recognized for derivative instruments that have also been offset under such master netting agreements.

FAIR VALUE MEASUREMENTS |

| Fair Value Disclosures [Abstract] | |
| FAIR VALUE MEASUREMENTS | NOTE 20. FAIR VALUE MEASUREMENTS Fair value is defined as the price at which an asset could be exchanged in a current transaction between knowledgeable, willing parties or the amount that would be paid to transfer a liability to a new obligor, not the amount that would be paid to settle the liability with the creditor. Where available, fair value is based on observable market prices or parameters or derived from such prices or parameters. Where observable prices or inputs are not available, valuation models are applied. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the instruments or market and the instruments’ complexity. Assets and liabilities recorded at fair value in the condensed balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair value. Hierarchical levels, defined by ASC 820 “Fair Value Measurement” (ASC 820), and directly related to the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities, are as follows: Level 1 — Inputs were unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. Level 2 — Inputs (other than quoted prices included in Level 1) were either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life. Level 3 — Inputs reflected management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration was given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model. We are required to separately disclose assets and liabilities measured at fair value on a recurring basis, from those measured at fair value on a nonrecurring basis. Nonfinancial assets measured at fair value on a nonrecurring basis are intangible assets and goodwill, which are reviewed for impairment annually in the fourth quarter and/or when circumstances or other events indicate that impairment may have occurred. Commodity Contracts We use commodity derivative contracts for certain raw materials and energy costs such as copper, zinc, ethane, electricity and natural gas to provide a measure of stability in managing our exposure to price fluctuations. Commodity contract financial instruments were valued primarily based on prices and other relevant information observable in market transactions involving identical or comparable assets or liabilities including both forward and spot prices for commodities. All commodity financial instruments were valued as a Level 2 under the fair value measurements hierarchy. Foreign Currency Contracts We enter into forward sales and purchase contracts to manage currency risk resulting from purchase and sale commitments denominated in foreign currencies. Foreign currency contract financial instruments were valued primarily based on relevant information observable in market transactions involving identical or comparable assets or liabilities including both forward and spot prices for currencies. All foreign currency contract financial instruments were valued as a Level 2 under the fair value measurements hierarchy. Financial Instruments The carrying values of cash and cash equivalents, accounts receivable and accounts payable approximated fair values due to the short-term maturities of these instruments. Since our long-term debt instruments may not be actively traded, the inputs used to measure the fair value of our long-term debt are based on current market rates for debt of similar risk and maturities and is classified as Level 2 in the fair value measurement hierarchy. As of June 30, 2025, December 31, 2024 and June 30, 2024, the fair value measurements of debt were $2,989.0 million, $2,779.0 million and $2,717.3 million, respectively. Nonrecurring Fair Value Measurements In addition to assets and liabilities that are recorded at fair value on a recurring basis, we record assets and liabilities at fair value on a nonrecurring basis as required by ASC 820. There were no assets or liabilities measured at fair value on a nonrecurring basis as of June 30, 2025, December 31, 2024 or June 30, 2024.
