Olin Corporation (Olin) 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 systems and growth 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.

On January 10, 2023, Blue Water Alliance (BWA), our joint venture with Mitsui & Co., Ltd. (Mitsui), began operations. BWA is an independent global trader of Electrochemical Unit (ECU)-based derivatives, focused on globally traded caustic soda and ethylene dichloride. Olin holds 51% interest and exercises control in BWA and the joint venture is consolidated in our consolidated financial statements in our Chlor Alkali Products and Vinyls segment, with Mitsui’s 49% interest in BWA classified as noncontrolling interest. All intercompany accounts and transactions are eliminated in consolidation.

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, 2023.

In March 2024, the SEC issued SEC Release No. 33-11042, Enhancement and Standardization of Climate-Related Disclosures for Investors, to enhance and standardize the climate-related disclosures provided by public companies. The final rule will require the disclosure of greenhouse gas emissions, including Scope 1 and Scope 2 emissions, which will be subject to third-party assurance, as well as climate-related targets and goals, and how the Board of Directors and management oversee climate-related risks. Within the notes to financial statements, the final rule requires disclosure of expenditures recognized, subject to certain thresholds, attributable to severe weather events. The final rule follows a compliance phase-in timeline, with the first requirements required to be adopted with our fiscal year ending December 31, 2025, followed in later years by greenhouse gas-related requirements. On April 4, 2024, the SEC voluntarily stayed the implementation of these disclosure requirements; however, we are currently evaluating the impact of the final rule on our disclosures.

In December 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (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.

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280) Improvements to Reportable Segment Disclosures. ASU 2023-07 will improve reportable segment disclosure requirements, primarily through enhanced segment expense disclosures on an interim and annual basis. The update is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with the option to early adopt at any time before the effective date. ASU 2023-07 requires adoption on a retrospective basis. We will adopt this standard beginning with our fiscal year ending December 31, 2024 and for interim periods beginning with our first quarter fiscal year 2025. We are currently evaluating the impact of the standard on our consolidated financial statements and disclosures.

On October 1, 2023, Olin acquired the assets of White Flyer Targets, LLC (White Flyer) from Reagent Diversified Holdings, Inc. for $63.5 million. The acquisition was financed with cash on hand. White Flyer designs, manufactures and sells recreational trap, skeet, international and sporting clay targets and has been included in Olin’s Winchester segment. We recorded the aggregate excess purchase price over identifiable net tangible and intangible assets acquired and liabilities assumed, which included a final allocation of $2.4 million of goodwill allocated to our Winchester segment and $4.5 million of intangible assets subject to amortization. The final total assets acquired, excluding goodwill and intangibles, and liabilities assumed amounted to $66.6 million and $10.0 million, respectively. The acquisition is not material, and therefore, supplemental pro forma financial information is not provided.

As a result of weak global resin demand and higher cost structures within the European region, we began a review of our global Epoxy asset footprint to optimize the most productive and cost-effective assets to support our strategic operating model. As part of this review, we announced operational cessations in the fourth quarter of 2022 and the first half of 2023 (collectively, Epoxy Optimization Plan).

On June 20, 2023, we announced we had made the decision to cease all remaining operations at our Gumi, South Korea facility, reduce epoxy resin capacity at our Freeport, TX facility, and reduce our sales and support staffing across Asia. These actions were substantially completed by December 31, 2023. On March 21, 2023, we announced we had made the decision to cease operations at our cumene facility in Terneuzen, Netherlands and solid epoxy resin production at our facilities in Gumi, South Korea and Guaruja, Brazil. The closures were completed in the first quarter 2023. During the fourth quarter of 2022, we committed to and completed a plan to close down one of our bisphenol production lines at our Stade, Germany site. We expect to incur additional restructuring charges through 2025 of approximately $15 million related to these actions.

During 2021, we announced that we had made the decision to permanently close our diaphragm-grade chlor alkali capacity, representing 400,000 tons, at our McIntosh, AL facility (McIntosh Plan). The closure was completed during the third quarter of 2022. We expect to incur additional restructuring charges through 2027 of approximately $20 million related to these actions.

On January 18, 2021, we announced we had made the decision to permanently close our trichloroethylene and anhydrous hydrogen chloride liquefaction facilities in Freeport, TX (collectively, Freeport 2021 Plan), which were completed in the fourth quarter of 2021. We expect to incur additional restructuring charges through 2025 of approximately $5 million related to these actions.

On December 11, 2019, we announced that we had made the decision to permanently close a chlor alkali plant with a capacity of 230,000 tons and our vinylidene chloride (VDC) production facility, both in Freeport, TX (collectively, Freeport 2019 Plan). The VDC facility and related chlor alkali plant were closed during the fourth quarter of 2020 and second quarter of 2021, respectively. We expect to incur additional restructuring charges through 2026 of approximately $15 million related to these actions.

Pretax restructuring charges related to these actions include facility exit costs, lease and other contract termination costs, employee severance and related benefits costs and the write-off of equipment and facilities. Pretax restructuring charges, by plan, for the three and six months ended June 30, 2024 and 2023, were as follows:

The following table summarizes the 2024 and 2023 activities by major component of these restructuring actions and the remaining balances of accrued restructuring costs as of June 30, 2024 and 2023:

The following table summarizes the cumulative restructuring charges of these restructuring actions by major component through June 30, 2024:

As of June 30, 2024, we have incurred cash expenditures of $112.2 million and non-cash charges of $79.9 million related to these restructuring actions. The remaining balance of $16.2 million is expected to be paid out through 2027.

Basic and diluted net income attributable to Olin Corporation per share are computed by dividing net income attributable to Olin Corporation by the weighted-average number of common shares outstanding. Diluted net income attributable to Olin Corporation per share reflects the dilutive effect of stock-based compensation.

The computation of dilutive shares does not include 2.0 million shares for both the three and six months ended June 30, 2024 and 1.3 million shares for both the three and six months ended June 30, 2023 as their effect would have been anti-dilutive.

We maintain a $425.0 million Receivables Financing Agreement (Receivables Financing Agreement) that is scheduled to mature on October 14, 2025. Under the Receivables Financing Agreement, our eligible trade receivables are used for collateralized borrowings and continue to be serviced by us. In addition, the Receivables Financing Agreement incorporates the net leverage ratio covenant that is contained in the $1,550.0 million Senior Credit Facility. As of June 30, 2024, December 31, 2023 and June 30, 2023, we had $298.8 million, $328.5 million and $234.8 million, respectively, drawn under the agreement. As of June 30, 2024, $429.8 million of our trade receivables were pledged as collateral and we had $0.5 million additional borrowing capacity under the Receivables Financing Agreement, which was limited by our borrowing base.

Olin also has trade accounts receivable factoring arrangements (AR Facilities) and pursuant to the terms of the AR Facilities, certain of our domestic subsidiaries may sell their accounts receivable up to a maximum of $175.5 million and certain of our foreign subsidiaries may sell their accounts receivable up to a maximum of €22.0 million. We will continue to service the outstanding accounts sold. These receivables qualify for sales treatment under ASC 860 “Transfers and Servicing” and, accordingly, the proceeds are included in net cash provided by operating activities in the condensed statements of cash flows. 

The following table summarizes the AR Facilities activity:

The factoring discount paid under the AR Facilities is recorded as interest expense on the condensed statements of operations. The factoring discount was $1.1 million and $1.3 million for the three months ended June 30, 2024 and 2023, respectively, and $2.1 million and $2.5 million for the six months ended June 30, 2024 and 2023, respectively. The agreements are without recourse and therefore no recourse liability had been recorded as of June 30, 2024.

Our condensed balance sheets included an allowance for doubtful accounts receivables of $12.6 million, $13.1 million and $13.0 million and other receivables of $91.1 million, $85.3 million and $81.7 million at June 30, 2024, December 31, 2023 and June 30, 2023, respectively, which were included in receivables, net.

Inventories consisted of the following:

Inventories under the LIFO method are based on annual estimates of quantities and costs as of year-end; therefore, the condensed financial statements at June 30, 2024 reflect certain estimates relating to inventory quantities and costs at December 31, 2024. The replacement cost of our inventories would have been approximately $166.1 million, $133.7 million and $173.8 million higher than reported at June 30, 2024, December 31, 2023 and June 30, 2023, respectively.

Included in other assets were the following:

For the six months ended June 30, 2024 and 2023, payments of $46.7 million and $29.6 million, respectively, were made under other long-term supply contracts for energy modernization projects in the U.S. Gulf Coast.

Amortization expense of $18.3 million and $17.8 million for the three months ended June 30, 2024 and 2023, respectively, and amortization expense of $36.6 million and $35.6 million for the six months ended June 30, 2024 and 2023, respectively, was recognized within cost of goods sold related to our long-term supply contracts and is reflected in depreciation and amortization on the condensed statements of cash flows.

Changes in the carrying value of goodwill were as follows:

(1)Includes cumulative goodwill impairment of $557.6 million and $142.2 million in Chlor Alkali Products and Vinyls and Epoxy, respectively.

Intangible assets consisted of the following:

Long-term loans, notes and other financing obligations, consisted of the following:

During the six months ended June 30, 2024 and 2023, activity of our outstanding debt included:

We maintain a $1,550.0 million senior credit facility (Senior Credit Facility) which includes a senior term loan facility with aggregate commitments of $350.0 million (Term Loan Facility) and a senior revolving credit facility with aggregate commitments of $1,200.0 million (Senior Revolving Credit Facility). The Term Loan Facility was fully drawn on the closing date with the proceeds of the Term Loan Facility used to refinance the loans and commitments outstanding under the existing facility. The Term Loan Facility requires principal amortization payments which began on March 31, 2023, at a rate of 0.625% per quarter through the end of 2024, increasing to 1.250% per quarter thereafter until maturity. The maturity date for the Senior Credit Facility is October 11, 2027.

We were in compliance with all covenants and restrictions under all our outstanding credit agreements as of June 30, 2024, and no event of default had occurred that would permit the lenders under our outstanding credit agreements to accelerate 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 Senior Revolving Credit Facility and the Receivables Financing Agreement. As of June 30, 2024, there were no covenants or other restrictions that limited our ability to borrow.

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 $0.8 million and $1.5 million for the six months ended June 30, 2024 and 2023, respectively.

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 three months ended June 30, 2023 included a net $12.0 million tax benefit, primarily associated with stock-based compensation, and prior year tax positions, partially offset by an expense from a net increase in the valuation allowance related to deferred tax assets in foreign jurisdictions and from a change in tax contingencies. Excluding these items, the effective tax rate for the three months ended June 30, 2023 of 25.4% was higher than the 21.0% U.S. federal statutory rate primarily due to state income tax and an increase in the valuation allowance related to losses in foreign jurisdictions, partially offset by favorable permanent salt depletion deductions.

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. The effective tax rate for the six months ended June 30, 2023 included a net $17.2 million tax benefit, primarily associated with stock-based compensation, remeasurement of deferred taxes due to a decrease in our state effective tax rates and prior year tax positions, partially offset by an expense from a net increase in the valuation allowance related to deferred tax assets in foreign jurisdictions and from a change in tax contingencies.

Excluding these items, the effective tax rate for the six months ended June 30, 2023 of 24.5% was higher than the 21.0% U.S. federal statutory rate primarily due to state income tax and an increase in the valuation allowance related to losses in foreign jurisdictions, 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. We will continue to monitor the expected impacts of any new guidance on our filing positions and will record the impacts as discrete income tax expense adjustments in the period the guidance is finalized or becomes effective.

As of June 30, 2024, we had $51.2 million of gross unrecognized tax benefits, which would have a net $51.4 million impact on the effective tax rate, if recognized. As of June 30, 2023, we had $58.7 million of gross unrecognized tax benefits, of which $56.8 million would have impacted the effective tax rate, if recognized. The amounts of unrecognized tax benefits were as follows:

As of June 30, 2024, we believe it is reasonably possible that our total amount of unrecognized tax benefits will decrease by approximately $36.3 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:

The Contributing Employee Ownership Plan (CEOP) is a defined contribution plan available to essentially all domestic employees. We provide a contribution to an individual retirement contribution account (Company Contributions) maintained with the CEOP equal to an amount between 5.0% and 7.5% of the employee’s eligible compensation. Employees generally vest in the value of the Company Contribution according to a schedule based on service. Participants vest 50% after 2 years of service and 100% after 3 years of service.

We also match a percentage of our employees CEOP contributions (Company Match), which are invested in the same investment allocation as the employee’s contributions. Employees immediately vest in company matching contributions.

Our contributions to the CEOP were as follows:

Stock-based compensation granted includes stock options, performance share awards, restricted stock awards and deferred directors’ compensation. Stock-based compensation expense was as follows:
