Notes to Condensed Financial Statements

(Unaudited)

NOTE 1. DESCRIPTION OF BUSINESS

Olin Corporation (Olin) is a Virginia corporation, incorporated in 1892, having its principal executive offices in Clayton, MO. We are a manufacturer concentrated in three business segments: Chlor Alkali Products and Vinyls, Epoxy and Winchester. The Chlor Alkali Products and Vinyls segment manufactures and sells chlorine and caustic soda, ethylene dichloride (EDC) and vinyl chloride monomer, methyl chloride, methylene chloride, chloroform, carbon tetrachloride, perchloroethylene, trichloroethylene, ~~and vinylidene chloride,~~ 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, bisphenol, cumene and phenol), allyl chloride, epichlorohydrin, liquid epoxy resins, solid epoxy resins and downstream products such as ~~differentiated~~converted epoxy resins and additives. The Winchester segment produces and sells sporting ammunition, reloading components, small caliber military ammunition and components, and industrial cartridges.

We have prepared the condensed financial statements included herein, without audit, pursuant to the rules and regulations of the ~~U.S.~~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, ~~2019.~~2020. Certain reclassifications were made to prior year amounts to conform to the ~~2020~~2021 presentation.

NOTE 2. RECENT ACCOUNTING PRONOUNCEMENTS

In March 2020, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) 2020-04, “Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (ASU 2020-04) which creates a new topic, Accounting Standards Codification (ASC) 848 “Reference Rate Reform.” Subsequent to the issuance of ASU 2020-04, ASC 848 was amended by ASU 2021-01, “Scope” which amended and clarified the application and scope of the aforementioned update. This update provides optional guidance to ease the potential accounting burden associated with transition away from reference rates that are expected to be discontinued at the end of 2021, at which time financial institutions will no longer be required to report information that is currently used to determine the London Interbank Offered Rate (LIBOR) and other reference rates. This update allows companies to treat contract amendments to existing contracts for the purpose of establishing a new reference rate as continuations of those contracts without additional analysis, as long as the modification was made to establish a new reference rate. This update applies prospectively to contract modifications. The optional guidance was effective on March 12, 2020 and can be adopted beginning January 1, 2020 or any date thereafter until December 31, 2022, at which time the optional guidance can no longer be applied to contract amendments to existing contracts. We adopted the provisions of this update on January 1, 2020 and will apply this guidance prospectively to contract modifications that are entered into for the purpose of establishing a new reference rate. We are currently evaluating the prospective impact on our consolidated financial statements; however, for the three months ended March 31, 2021, this update did not have a material impact on our consolidated financial statements.

NOTE 2.3. RESTRUCTURING CHARGES

On March 15, 2021, we announced that we had made the decision to permanently close approximately 50% of our diaphragm-grade chlor alkali capacity, representing 200,000 tons, at our McIntosh, AL facility (McIntosh Plan). The closure was completed in the first quarter of 2021. For the three months ended March 31, 2021, we recorded pretax restructuring charges of $4.4 million for lease and other contract termination costs related to this action. We expect to incur additional restructuring charges through 2022 of approximately $5 million related to this action.

On January 18, 2021, we announced that we had made the decision to permanently close our trichloroethylene and anhydrous hydrogen chloride liquefaction facilities in Freeport, TX (collectively, Freeport 2021 Plan), before the end of 2021. For the three months ended March 31, 2021, we recorded pretax restructuring charges of $1.3 million for facility exit costs

On December 10, 2018, we announced that we had made the decision to permanently close the ammunition assembly operations at our Winchester facility in Geelong, Australia. Subsequent to the facility’s closure, product for customers in the region will be sourced from Winchester manufacturing facilities located in the United States. For the three months ended March 31, 2019, we recorded pretax restructuring charges of $0.1 million for lease and other contract termination costs related to this action. For the three months ended March 31, 2019, we recorded additional pretax restructuring charges of $1.4 million for employee severance and related benefit costs related to our Winchester operations.

On March 21, 2016, we announced that we had made the decision to close a combined total of 433,000 tons of chlor alkali capacity across three separate ~~locations.~~locations (collectively, Chlor Alkali 2016 Plan). Associated with this action, we have permanently closed our Henderson, NV chlor alkali plant with 153,000 tons of capacity and have reconfigured the site to manufacture bleach and distribute caustic soda and hydrochloric acid. Also, the capacity of our Niagara Falls, NY chlor alkali plant has been reduced from 300,000 tons to 240,000 tons and the chlor alkali capacity at our Freeport, TX facility was reduced by 220,000 tons. This 220,000 ton reduction was entirely from diaphragm cell capacity. For the three months ended March 31, ~~2020~~2021 and ~~2019,~~2020, we recorded pretax restructuring charges of ~~$1.7~~$0.4 million and ~~$2.5~~$1.7 million, respectively, for facility exit costs, employee severance and related benefit costs and lease and other contract termination costs related to these actions. We expect to incur additional restructuring charges through ~~2020~~2021 of approximately $5$2 million related to these capacity reductions.

NOTE 3.4. ACCOUNTS RECEIVABLES

~~On July 16, 2019, our existing~~We maintain a $250.0 million Receivables Financing Agreement ~~was extended~~(Receivables Financing Agreement) that is scheduled to mature July 15, ~~2022 and downsized to~~ ~~$10.0 million~~ with the option to expand (Receivables Financing Agreement). During the three months ended March 31, 2020, we amended the Receivables Financing Agreement to expand the borrowing capacity and borrowed $150.0 million. During April 2020, we expanded the facility and borrowed an additional $100.0 million.2022. The Receivables Financing Agreement includes a minimum borrowing requirement of 50% of the facility limit or available borrowing capacity, ~~or facility limit,~~ whichever is ~~greater, beginning on October 1, 2020.~~lesser. The administrative agent for our Receivables Financing Agreement is PNC Bank, National Association. 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 secured leverage covenant that is contained in the ~~$2,000.0~~$1,615.0 million senior secured credit facility. As of March 31, ~~2020, $345.2~~2021, $393.9 million of our trade receivables were pledged as collateral.

~~NOTE 4. ALLOWANCE FOR DOUBTFUL ACCOUNTS RECEIVABLES~~

We evaluate the collectibility of financial instruments based on our current estimate of credit losses expected to be incurred over the life of the financial instrument. The only significant financial instrument which creates exposure to credit losses are customer accounts receivables. We measure credit losses on uncollected accounts receivable throughOur condensed balance sheets included an allowance for doubtful accounts ~~receivable~~receivables of $12.2 million, $12.3 million and $11.8 million and other receivables of $60.3 million, $62.4 million and $89.2 million at March 31, 2021, December 31, 2020 and March 31, 2020, respectively, which is based on a combination of factors including both historical collection experience and reasonable estimates that affect the expected collectibility of the receivable. These factors include historical bad debt experience, industry conditions of the customer or group of customers, geographical region, credit ratings and general market conditions. We groupwere included in receivables, ~~together for purposes of estimating credit losses when customers have similar risk characteristics; otherwise, the estimation is performed on the individual receivable.~~net.

This estimate is periodically adjusted when we become aware of a specific customer’s inability to meet its financial obligations (e.g., bankruptcy filing) or as a result of changes in the overall aging of accounts receivable. While we have a large number of customers that operate in diverse businesses and are geographically dispersed, a general economic downturn in any of the industry segments in which we operate could result in higher than expected defaults, and, therefore, the need to revise estimates for the provision for doubtful accounts could occur.

~~Allowance for doubtful accounts receivables consisted of the following:~~

Inventories are valued at the lower of cost and net realizable value. For U.S. inventories, inventory costs are determined principally by the last-in, first-out (LIFO) method of inventory accounting while for international inventories, inventory costs are determined principally by the first-in, first-out (FIFO) method of inventory accounting. Cost for other inventories has been determined principally by the average-cost method (primarily operating supplies, spare parts and maintenance parts). Elements of costs in inventories included raw materials, direct labor and manufacturing overhead. Inventories under the LIFO method are based on annual estimates of quantities and costs as of year-end; therefore, the condensed financial statements at March 31, ~~2020~~2021 reflect certain estimates relating to inventory quantities and costs at December 31, ~~2020.~~2021. The replacement cost of our inventories would have been approximately ~~$42.6~~$58.0 million, ~~$49.5~~$48.2 million and ~~$70.6~~$42.6 million higher than reported at March 31, ~~2020,~~2021, December 31, ~~2019~~2020 and March 31, ~~2019,~~2020, respectively.

We have entered into various arrangements for the long-term supply of ethylene and electricity. A payment of $461.0 million was made during the second quarter of 2020 associated with a previously executed option to reserve additional ethylene at producer economics from The Dow Chemical Company (Dow). The original liability was discounted and recorded at present value as of March 31, 2017. For the three months ended March 31, 2020, $4.0 million of interest expense was recorded for accretion on the 2020 payment liability discount.

~~On January 1, 2019, we sold our 9.1% limited partnership interest in Bay Gas Storage Company, Ltd. (Bay Gas) for $20.0 million. The sale closed on February 7, 2019 which resulted in a gain~~

Amortization expense of ~~$11.2~~$17.5 million and $22.3 million for the three months ended March 31, ~~2019 which was recorded to other income in the condensed statements of operations.~~

~~On October 5, 2015 (the Closing Date), we completed the acquisition (the Acquisition) from The Dow Chemical Company (Dow) of its U.S. Chlor Alkali~~2021 and Vinyl, Global Chlorinated Organics and Global Epoxy businesses (collectively, the Acquired Business). In connection with the Acquisition, Olin and Dow entered into arrangements for the long-term supply of ethylene by Dow to Olin, pursuant to which, among other things, Olin made upfront payments in order to receive ethylene at producer economics and for certain reservation fees and for the option to obtain additional ethylene at producer economics. During 2016, we exercised one of the options to reserve additional ethylene at producer economics. During 2017, an additional payment of $209.4 million was made in connection with this option which increased the value of the long-term asset.

~~Amortization expense of $9.4 million for both the three months ended March 31,~~ 2020, ~~and 2019~~respectively, was recognized within cost of goods sold related to ~~these~~our long-term supply contracts and is reflected in depreciation and amortization on the condensed statements of cash flows. The long-term supply contracts are monitored for impairment each reporting period.

On February 27, 2017, we exercised the remaining option to reserve additional ethylene at producer economics from Dow. In connection with the exercise of this option, we also secured a long-term customer arrangement. As a result, an additional payment will be made to Dow that is not to exceed $493 million on or about the fourth quarter of 2020. Olin has recognized a long-term asset and other liability of $439.9 million, which represented the present value of the additional

estimated payment. The discounted amount of $52.7 million will be recorded as interest expense through the fourth quarter of 2020. For both the three months ended March 31, 2020 and 2019, $4.0 million of interest expense was recorded for accretion on the 2020 payment discount. The liability balance as of March 31, 2020 of $480.8 million was reclassified to accrued liabilities from other liabilities on the condensed balance sheet.

Goodwill is not amortized, but is reviewed for impairment annually in the fourth quarter and/or when circumstances or other events indicate that impairment may have occurred. Circumstances that are considered as part of the qualitative assessment and could trigger a quantitative impairment test include, but are not limited to: a significant adverse change in the business climate; a significant adverse legal judgment; adverse cash flow trends; an adverse action or assessment by a government agency; unanticipated competition; sustained decline in our stock price; and a significant restructuring charge within a reporting unit. During the three months ended March 31, 2020, we identified triggering events associated with an overall decrease in our stock price, an adverse change in the business climate and a significant reduction in near-term cash flow projections. As a result of these events, we performed a quantitative goodwill impairment test during the first quarter of 2020. We used a discounted cash flow approach to develop the estimated fair value of our reporting units. Based on the aforementioned analysis, the estimated fair value of our reporting units exceeded the carrying value of the reporting units and no impairment charges were recorded.

(1) The discount rate, profitability assumptions and terminal growth rate of our reporting units and the cyclical nature of the chlor alkali industry were the material assumptions utilized in the discounted cash flow model used to estimate the fair value of each reporting unit. The discount rate reflects a weighted-average cost of capital, which is calculated based on observable market data. Some of this data (such as the risk free or treasury rate and the pretax cost of debt) are based on the market data at a point in time. Other data (such as the equity risk premium) are based upon market data over time for a peer group of companies in the chemical manufacturing or distribution industries with a market capitalization premium added, as applicable.

The discounted cash flow analysis requires estimates, assumptions and judgments about future events. Our analysis uses our internally generated long-range plan. Our discounted cash flow analysis uses the assumptions in our long-range plan about terminal growth rates, forecasted capital expenditures and changes in future working capital requirements to determine the implied fair value of each reporting unit. The long-range plan reflects management judgment, supplemented by independent chemical industry analyses which provide multi-year chlor alkali industry operating and pricing forecasts.

We believe the assumptions used in our goodwill impairment analysis are appropriate and result in reasonable estimates of the implied fair value of each reporting unit. However, given the economic environment and the uncertainties regarding the impact on our business, there can be no assurance that our estimates and assumptions, made for purposes of our goodwill impairment testing, will prove to be an accurate prediction of the future. In order to evaluate the sensitivity of the fair value calculation on the goodwill impairment test, we applied three separate sensitivities: a hypothetical 10% decrease to the fair value of each reporting unit, a hypothetical decrease of 100-basis points in our terminal growth rate and an increase of 100-basis points in our weighted-average cost of capital to test the fair value calculation. The hypothetical 10% decrease to the fair value of our Chlor Alkali Products and Vinyls, ~~reporting unit exceeded the carrying value of the reporting unit, but was not significantly in excess of the carrying value. In all other cases, the estimated fair value of our~~ Epoxy and ~~Chlor Alkali Products~~total goodwill balances are net of $557.6 million, $142.2 million and ~~Vinyls reporting units derived in these sensitivity calculations did not exceed~~$699.8 million of accumulated impairment losses recorded during the ~~carrying value~~third quarter of ~~our reporting units. If our assumptions regarding future performance are not achieved, we may be required to record goodwill impairment charges in~~2020.

~~future periods. It is not possible at this time to determine if any such future impairment charge would result or, if it does, whether such charge would be material.~~

Intangible assets consisted of the following:

NOTE 8. EARNINGS PER SHARE

Basic and diluted net income (loss) ~~income~~ per share are computed by dividing net income (loss) ~~income~~ by the weighted-average number of common shares outstanding. Diluted net income (loss) ~~income~~ per share reflects the dilutive effect of stock-based compensation.

NOTE 9. ENVIRONMENTAL

We are party to various government and private environmental actions associated with past manufacturing facilities and former waste disposal sites. Environmental provisions charged to income, which are included in costs of goods sold, were as follows:

Environmental expense for the three months ended March 31, 2021 includes $2.2 million of insurance recoveries for environmental costs incurred and expensed in prior periods. The condensed balance sheets included reserves for future environmental expenditures to investigate and remediate known sites amounting to ~~$139.1~~$147.2 million, ~~$139.0~~$147.2 million and ~~$125.5~~$139.1 million at March 31, ~~2020,~~2021, December 31, ~~2019~~2020 and March 31, ~~2019,~~2020, respectively, of which ~~$122.1~~$128.2 million, ~~$122.0~~$128.2 million and ~~$108.5~~$122.1 million, respectively, were classified as other noncurrent liabilities.

~~Environmental provisions charged to income, which are included in costs of goods sold, were $2.6 million and $1.8 million for the three months ended March 31, 2020 and 2019, 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 or results of operations.

In connection with the October 5, 2015 acquisition of Dow’s U.S. Chlor Alkali and Vinyl, Global Chlorinated Organics and Global Epoxy businesses, the prior owner of the businesses retained liabilities relating to releases of hazardous materials and violations of environmental law to the extent arising prior to October 5, 2015.

NOTE 10. COMMITMENTS AND CONTINGENCIES

Olin and Oxy Vinyls, L.P. (Oxy) have a long-term chlorine supply agreement, which is the subject of a pricing dispute. The dispute is pending in the United States District Court for the Southern District of Texas, and we currently anticipate trial will be scheduled for third quarter 2020. Any additional losses related to this contract dispute are not currently estimable because of unresolved questions of fact and law but, if resolved unfavorably to Olin, they could have a material adverse effect on our financial position, cash flows or results of operations.

Plaintiffs seek an unspecified amount of damages and injunctive relief.

Olin, K.A. Steel Chemical, Olin Canada ULC, 3229897 Nova Scotia Co. (wholly owned subsidiaries of Olin) and other alleged caustic soda producers were named as defendants in a proposed class action civil lawsuit filed on October 7, 2020 in the Quebec Superior Court (Province of Quebec) on behalf of the respective named plaintiff and a putative class comprised of all Canadian persons and entities who, between October 1, 2015 and the date of the eventual class action certification, directly or indirectly purchased caustic soda or products containing caustic soda, produced by one or more of the defendants. Olin, K.A. Steel Chemical, Olin Canada ULC, 3229897 Nova Scotia Co. and other alleged caustic soda producers were also named as defendants in a proposed class action civil lawsuit filed November 13, 2020 in the Federal Court of Canada on behalf of the respective named plaintiff and a putative class comprised of all legal persons in Canada who, at any time on or after October 1, 2015 to the present, directly or indirectly purchased caustic soda. The other defendants named in the two Canadian lawsuits are Occidental Petroleum Corporation, Occidental Chemical Corporation, Oxy Canada Sales, Inc., Westlake Chemical Corporation, Axiall Canada, Inc., Shin-Etsu Chemical Co., Ltd., Shintech Incorporated, Formosa Plastics Corporation, and Formosa Plastics Corporation, U.S.A. The lawsuits allege the defendants conspired to fix, raise, maintain control, and stabilize the price of caustic soda, divide and allocate markets, sales, customers and territories, fix, maintain, control, prevent, restrict, lessen or eliminate production and supply of caustic soda, and agree to idle capacity of production and/or refrain from increasing their production capacity. Plaintiffs seek an unspecified amount of damages, including punitive damages.

We believe we have meritorious legal positions and will continue to represent our interests vigorously in this matter. Any losses related to this matter are not currently estimable because of unresolved questions of fact and law, but if resolved unfavorably to Olin, could have a material adverse effect on our financial position, cash flows or results of operations.

We, and our subsidiaries, are defendants in various other legal actions (including proceedings based on alleged exposures to asbestos) incidental to our past and current business activities. As of March 31, ~~2020,~~2021, December 31, ~~2019~~2020 and March 31, ~~2019,~~2020, our condensed balance sheets included accrued liabilities for these other legal actions of ~~$12.0~~$13.8 million, ~~$12.4~~$13.5 million and ~~$15.8~~$12.0 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 other legal actions will materially adversely affect our financial position, cash flows or results of operations. ~~In connection with the October 5, 2015 acquisition~~

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.

NOTE 11. SHAREHOLDERS’ EQUITY

NOTE 12. SEGMENT INFORMATION

We define segment results as income (loss) before interest expense, interest income, goodwill impairment charges, other operating income (expense), non-operating pension income, other income and income taxes. 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. Chlorine used in our Epoxy segment is transferred at cost from the Chlor Alkali Products and Vinyls segment. Sales and profits are recognized in the Chlor Alkali Products and Vinyls segment for all caustic soda generated and sold by Olin. Sales are attributed to geographic areas based on customer location.

NOTE 13. STOCK-BASED COMPENSATION

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

($ in millions)
Stock-based compensation $ 2.0
$ 5.6
Mark-to-market adjustments (3.0 ) 1.3
Total expense $ (1.0 ) $ 6.9

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 with the following weighted-average assumptions:

Grant date 2020 2019
Dividend yield 4.60 % 3.05 %
Risk-free interest rate 1.44 % 2.51 %
Expected volatility 36 % 34 %
Expected life (years) 6.0
6.0
Weighted-average grant fair value (per option) $ 3.64
$ 6.76
Weighted-average exercise price $ 17.33
$ 26.26
Shares granted 2,665,700
1,575,900

Dividend yield was based on our current dividend yield as of the option grant date. Risk-free interest rate was based on zero coupon U.S. Treasury securities rates for the expected life of the options. Expected volatility of Olin common stock was based on our historical stock price movements, as we believe that historical experience is the best available indicator of the expected volatility. Expected life of the option grant was based on historical exercise and cancellation patterns, as we believe that historical experience is the best estimate of future exercise patterns.

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 3-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 3-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. The fair value of each performance stock award based on net income was estimated on the date of grant, using the current stock price. The fair value of each performance stock award based on TSR was estimated on the date of grant, using a Monte Carlo simulation model with the following weighted average assumptions:


Grant date	2021
Risk-free interest rate	0.23		%
Expected volatility of Olin common stock	55		%
Expected average volatility of peer companies	50		%
Average correlation coefficient of peer companies	0.50
Expected life (years)	3.0
Grant date fair value (TSR based award)	$	39.96
Grant date fair value (net income based award)	$	28.99
Awards granted	248,700

Risk-free interest rate was based on zero coupon U.S. Treasury securities rates for the expected life of the performance stock awards. 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 stock award grant was based on historical exercise and cancellation patterns, as we believe that historical experience is the best estimate of future exercise patterns.

On ~~July 16, 2019,~~March 31, 2021, Olin redeemed $315.0 million of the outstanding 10.00% senior notes due 2025 (2025 Notes). The 2025 Notes were redeemed at 105.0% of the principal amount of the 2025 Notes, resulting in a redemption premium of $15.8 million. The 2025 Notes were redeemed by drawing $315.0 million of the Delayed Draw Term Loan along with utilizing $15.8 million of cash on hand.

On January 15, 2021, Olin redeemed the remaining $120.0 million of the outstanding 9.75% senior notes due 2023 (2023 Notes). The 2023 Notes were redeemed at 102.438% of the principal amount of the 2023 Notes, resulting in a redemption premium of $2.9 million. The remaining 2023 Notes were redeemed by utilizing $122.9 million of cash on hand.

On February 24, 2021, we entered into a ~~new five-year, $2,000.0~~$1,615.0 million senior secured credit facility ~~(2019 Senior~~(Senior Secured Credit Facility)~~, which replaced the~~ that amended our existing ~~$1,975.0~~$1,300.0 million senior secured credit facility. The ~~2019~~ Senior Secured Credit Facility includes a senior ~~unsecured~~secured delayed-draw term loan facility ~~in an~~with aggregate ~~principal amount~~commitments of ~~up to $1,200.0~~$315.0 million (Delayed Draw Term Loan), a senior secured term loan facility with aggregate commitments of $500.0 million (2020 Term Loan ~~Facility). The~~and together with the Delayed Draw Term Loan, ~~Facility will be available on a delayed basis in up to 3 draws to be made on or prior to November 29, 2020. The Delayed Draw~~the Senior Secured Term Loan Facility includes principal amortization amounts payable beginning the quarter ending after the facility is fully drawn at a rate of 5.0% per annum for the first two years, increasing to 7.5% per annum for the following yearLoans) and ~~to 10.0% per annum for the last two years. The 2019 Senior Credit Facility also includes~~ a senior ~~unsecured~~secured revolving credit facility with aggregate commitments in an amount equal to $800.0 million ~~(2019 Senior~~(Senior Revolving Credit Facility)~~, which was increased from $600.0 million.~~. The ~~2019~~maturity date for the Senior Secured Credit Facility is July 16, 2024. The amendment modified the pricing grid for the Senior Secured Credit Facility by reducing applicable interest rates on the borrowings under the facility.

On March 30, 2021, Olin drew the entire $315.0 million of the Delayed Draw Term Loan. The Senior Secured Term Loans include principal amortization amounts payable beginning June 30, 2021 at a rate of 1.25% per quarter through the end of 2022, increasing to 1.875% per quarter during 2023 and 2.50% per quarter thereafter until maturity. The Senior Revolving Credit Facility includes a $100.0 million letter of credit subfacility. At March 31, ~~2020,~~2021, we had $799.6 million available under our $800.0 million ~~2019~~ Senior Revolving Credit Facility because we had issued $0.4 million of letters of credit. ~~The maturity date~~

Annual maturities of long-term debt at March 31, 2021, including finance lease obligations, are $31.6 million in 2021, $366.9 million in 2022, $62.1 million in 2023, $753.3 million in 2024, $688.1 million in 2025 and a total of $1,883.0 million thereafter.

For the three months ended March 31, 2021, we recognized interest expense of $4.8 million for the ~~2019 Senior Credit Facility is July 16, 2024 at which point all outstanding Delayed Draw Term Loan Facility~~write-off of unamortized deferred debt issuance costs and ~~2019 Senior Revolving Credit Facility balances will become due and payable. In December 2019, Olin amended~~deferred losses on fair value interest rate swaps related to the ~~2019 Senior Credit Facility which amended the restrictive covenants~~partial redemption of the ~~agreement, including expanding~~2025 Notes. For the ~~coverage and leverage ratios~~three months ended March 31, 2021, we paid debt issuance costs of $3.1 million for the amendments to ~~be less restrictive over the next two and a half years.~~our Senior Secured Credit Facility.

Under the ~~2019~~ Senior Secured Credit Facility, we may select various floating rate borrowing options. The actual interest rate paid on borrowings under the ~~2019~~ Senior Secured Credit Facility is based on a pricing grid which is dependent upon the net leverage ratio as calculated under the terms of the applicable facility for the prior fiscal quarter. The ~~2019~~ Senior Secured Credit Facility includes various customary restrictive covenants, including restrictions related to the ratio of secured debt to earnings before interest expense, taxes, depreciation and amortization ~~(leverage~~(secured leverage ratio) and the ratio of earnings before interest expense, taxes, depreciation and amortization to interest expense (coverage ratio). The calculation of secured debt in our secured leverage ratio excludes borrowings under the Receivables Financing Agreement, up to a maximum of $250.0 million. As of March 31, 2021, the only secured borrowings included in the secured leverage ratio were $815.0 million for our Senior Secured Term Loans and $153.0 million for our Go Zone and Recovery Zone bonds. Compliance with these covenants is determined quarterly. We were in compliance with all covenants and restrictions under all our outstanding credit agreements as of March 31, ~~2020,~~2021, and no event of default had occurred that would permit the lenders under our outstanding credit agreements to accelerate the debt if not

On April 14, 2021, Olin notified bondholders that we intend to redeem the remaining $185.0 million of the outstanding 2025 Notes. The 2025 Notes are expected to be redeemed at 105.0% of the principal amount of the 2025 Notes, resulting in a redemption premium of $9.3 million. The outstanding 2025 Notes are expected to be redeemed by utilizing cash on hand.

NOTE 15. CONTRIBUTING EMPLOYEE OWNERSHIP PLAN

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 maintained with the CEOP equal to an amount of between 5.0% and 7.5% of the employee’s eligible compensation. The defined contribution plan expense for the three months ended March 31, ~~2020~~2021 and ~~2019~~2020 was $~~8.2~~8.7 million and ~~$9.4~~$8.2 million, respectively.

Company matching contributions are invested in the same investment allocation as the employee’s contribution. Our matching contributions for eligible employees for the three months ended March 31, 2021 and 2020 ~~and 2019~~ were ~~$0.8~~$3.2 million and ~~$3.9~~$0.8 million, respectively. Effective January 1, 2020, we suspended the match on all salaried and non-bargaining hourly employees’ contributions, and moved to a discretionary contribution model with contributions contingent upon company-wide financial performance. During 2020, we did not make a discretionary matching contribution. Effective January 1, 2021, we reinstated the match on all salaried and non-bargaining hourly employees’ contributions, which provides for a maximum 3% matching contribution based on the level of participant contributions.

NOTE 16. 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.

NOTE 17. INCOME TAXES

The effective tax rate for the three months ended March 31, 2021 included a benefit associated with prior year tax positions, a benefit associated with stock-based compensation, an expense from remeasurement of deferred taxes due to an increase in our state effective tax rates and an expense from a change in tax contingencies. These factors resulted in a net $1.3 million tax benefit. After giving consideration to these items the effective tax rate for the three months ended March 31, 2021 of 20.8% was lower than the 21% U.S. federal statutory rate primarily due to a net decrease in the valuation allowance related to utilization of losses in foreign jurisdictions and favorable permanent salt depletion deductions, partially offset by state taxes, foreign income inclusions and foreign income taxes. The effective tax rate for the three months ended March 31, 2020 included an expense associated with stock-based compensation, an expense associated with prior year tax positions and an expense from a change in tax contingencies. These factors resulted in a net $1.2 million tax expense. After giving consideration to these items, the effective tax rate for the three months ended March 31, 2020 of 25.6% was higher than the 21% U.S. federal statutory rate primarily due to state taxes, foreign income taxes and favorable permanent salt depletion deductions, partially offset by foreign income inclusions and a net increase in the valuation allowance related to losses in foreign jurisdictions. ~~The effective tax rate for the three months ended~~

As of March 31, ~~2019 included a benefit associated with stock-based compensation, a benefit associated with prior year~~2021, we had $21.6 million of gross unrecognized tax ~~positions and a benefit from~~benefits, which would have a net ~~decrease in the valuation allowance related to state deferred tax assets. These factors resulted in a net $0.8~~$21.5 million ~~tax benefit. After giving consideration to these items,~~impact on the effective tax rate, for the three months ended March 31, 2019 of 23.0% was higher than the 21% U.S. federal statutory rate, primarily due to state and foreign income taxes, foreign income inclusions and a net increase in the valuation allowance related to losses in foreign jurisdictions, partially offset by favorable permanent salt depletion deductions.

if recognized. As of March 31, 2020, we had $21.5 million of gross unrecognized tax benefits, ~~which would have a net $21.3 million impact on the effective tax rate, if recognized. As of March 31, 2019, we had $34.4 million of gross unrecognized tax benefits,~~ of which ~~$33.5~~$21.3 million would have impacted the effective tax rate, if recognized. The amount of unrecognized tax benefits was as follows:

Balance at beginning of year $ 22.8
$ 33.8
Decreases for prior year tax positions (1.8 ) —
Increases for current year tax positions 0.5
0.6
Balance at end of period $ 21.5
$ 34.4

As of March 31, ~~2020,~~2021, we believe it is reasonably possible that our total amount of unrecognized tax benefits will decrease by approximately ~~$3.8~~$6.9 million over the next twelve months. The anticipated reduction primarily relates to settlements with taxing 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. Our 2016 U.S. federal income tax return is currently under examination by the Internal Revenue Service. 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:

NOTE 18. 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.

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. At March 31, ~~2020,~~2021, we had outstanding forward contracts to buy foreign currency with a notional value of ~~$162.3~~$212.3 million and to sell foreign currency with a notional value of ~~$84.8~~$110.8 million. 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 or results of operations. At December 31, ~~2019,~~2020, we had outstanding forward contracts to buy foreign currency with a notional value of ~~$140.6~~$169.9 million and to sell foreign currency with a notional value of ~~$99.2~~$113.6 million. At March 31, ~~2019,~~2020, we had outstanding forward contracts to buy foreign currency with a notional value of ~~$110.5~~$162.3 million and to sell foreign currency with a notional value of ~~$89.7~~$84.8 million.

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:

We use cash flow hedges for certain raw material and energy costs such as copper, zinc, lead, 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 March 31, ~~2020,~~2021, we had open derivative contract positions through 2027. If all open futures contracts had been settled on March 31, ~~2020,~~2021, we would have recognized a pretax ~~loss~~gain of ~~$41.1~~$37.6 million.

If commodity prices were to remain at March 31, ~~2020~~2021 levels, approximately ~~$26.7~~$21.4 million of deferred ~~losses,~~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.

We use interest rate swaps as a means of minimizing cash flow fluctuations that may arise from volatility in interest rates of our variable-rate borrowings. In April 2016, we entered into three tranches of forward starting interest rate swaps whereby we agreed to pay fixed rates to the counterparties who, in turn, pay us floating rates on $1,100.0 million, $900.0 million, and $400.0 million of our underlying floating-rate debt obligations. Each tranche’s term length was for twelve months beginning on December 31, 2016, 2017 and 2018, respectively. We designated the swaps as cash flow hedges of the risk of changes in interest payments associated with our variable-rate borrowings. In July 2019, we terminated the remaining interest rate swap. For the three months ended March 31, 2019, $1.3 million of income was recorded to interest expense on the accompanying condensed statements of operations related to these swap agreements.

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. ~~As of March 31,~~

In August 2019, we terminated the ~~total notional amounts of our~~ interest rate swaps designated as fair value hedges ~~was $500.0 million.~~

~~In April 2016, we entered into interest rate swaps on $250.0~~which resulted in a loss of $2.3 million ~~of our underlying fixed-rate debt obligations, whereby we agreed to pay variable rates~~that will be deferred as an offset to the ~~counterparties who,~~carrying value of the related debt and will be recognized to interest expense. In March 2021, we redeemed a portion of the 2025 Notes, which resulted in ~~turn, pay us fixed rates. In October 2016, we entered into interest rate swaps on an additional $250.0 million~~recognition of ~~our underlying fixed-rate debt obligations, whereby we agreed to pay variable rates to~~a portion of the ~~counterparties who, in turn, pay us fixed rates. We designated the April 2016 and October 2016~~outstanding deferred fair value interest rate swap ~~agreements as fair value hedges~~loss of the risk of changes in the value of fixed-rate debt due to changes in interest rates for a portion of our fixed-rate borrowings. In August 2019, we terminated the April 2016 and October 2016 interest rate swaps.$1.1 million. For the three months ended March 31, ~~2019, $0.7~~2021 and 2020, $1.2 million and $0.1 million, respectively, of expense was recorded to interest expense on the accompanying condensed statements of operations related to these swap agreements.

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. The table disaggregates our net derivative assets and liabilities into gross components on a contract-by-contract basis before giving effect to master netting arrangements:

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 March 31, ~~2020,~~2021, December 31, ~~2019~~2020 and March 31, ~~2019,~~2020, 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.

NOTE 19. 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.

Table of Contents

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 Measurements and Disclosures” (ASC 820) are directly related to the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities, and 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.

Determining which hierarchical level an asset or liability falls within requires significant judgment. We evaluate our hierarchy disclosures each quarter. The following table summarizes the assets and liabilities measured at fair value in the condensed balance sheets:

~~Interest Rate Swaps~~

Interest rate swap financial instruments were valued using the “income approach” valuation technique. This method used valuation techniques to convert future amounts to a single present amount. The measurement was based on the value indicated by current market expectations about those future amounts. We use interest rate swaps as a meansTable of ~~managing interest expense and floating interest rate exposure to optimal levels.~~Contents

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. We use commodity derivative contracts for certain raw materials and energy costs such as copper, zinc, lead, ethane, electricity and natural gas to provide a measure of stability in managing our exposure to price fluctuations.

Foreign Currency Contracts

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. We enter into forward sales and purchase contracts to manage currency risk resulting from purchase and sale commitments denominated in foreign currencies.

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. ~~The~~Since our long-term debt instruments may not be actively traded, the inputs used to measure the fair value of our long-term debt ~~was determined~~are based on current market rates for debt of similar risk and ~~maturities. The following table summarizes~~maturities and is classified as Level 2 in the fair value measurement hierarchy. As of March 31, 2021, December 31, 2020 and March 31, 2020, the fair value measurements of debt were $4,011.5 million, $4,177.2 million and ~~the actual debt recorded on our condensed balance sheets:~~$3,322.3 million, respectively.

~~NOTE 20. SUPPLEMENTAL GUARANTOR FINANCIAL INFORMATION~~

In October 2015, Blue Cube Spinco LLC (the Issuer) issued $720.0 million aggregate principal amount of 9.75% senior notes due October 15, 2023 (2023 Notes) and $500.0 million aggregate principal amount of 10.00% senior notes due October 15, 2025 (2025 Notes and, together with the 2023 Notes, the Notes). During 2016, the Notes were registered under the Securities Act of 1933, as amended. The Issuer was formed on March 13, 2015 as a wholly owned subsidiary of Dow and upon closing of the Acquisition became a 100% owned subsidiary of Olin (the Parent Guarantor). The Notes are fully and unconditionally guaranteed by the Parent Guarantor.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

We are a leading vertically-integrated global manufacturer and distributor of chemical products and a leading ~~U.S.~~United States (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. Chlor Alkali Products and Vinyls operating rates are closely tied to the general economy. Each segment has a commodity element to ~~it, and therefore, our ability to influence pricing is quite limited on the portion of the segment’s business that is strictly commodity.~~it.

Our Chlor Alkali Products and Vinyls segment is partially a commodity business where all supplier products are similar and price is the major supplier selection criterion. ~~We have little or no ability~~Pricing for these products is subject to ~~influence prices in the large, global commodity markets.~~a variety of factors, some of which are outside of our control. Our Chlor Alkali Products and Vinyls segment produces some of the most widely used chemicals in the world that can be upgraded into a wide variety of downstream chemical products used in many end-markets. ~~Cyclical price swings, driven by changes~~Changes in supply/demand can be abrupt and significant and, given capacity in our Chlor Alkali Products and Vinyls segment, can lead to ~~very~~ significant changes in our overall profitability.

The Epoxy segment consumes some products manufactured by the Chlor Alkali Products and Vinyls segment. The Epoxy segment’s upstream and midstream products are ~~predominately~~partially commodity markets. ~~We have little or no ability~~Pricing for these products is subject to ~~influence prices in these large, global commodity markets.~~a variety of factors, some of which are outside of our control. While competitive differentiation exists through downstream customization and product development opportunities, pricing is extremely competitive with a broad range of competitors across the globe.

Winchester also has a commodity element to its business, but a majority of Winchester ammunition is sold as a branded consumer product where there are opportunities to differentiate certain offerings through innovative new product development and enhanced product performance. While competitive pricing versus other branded ammunition products is important, it is not the only factor in product selection.

~~COVID-19~~Winter Storm Uri

~~The 2019 Novel Coronavirus (COVID-19) global pandemic,~~Olin’s Freeport, TX facility was affected by Winter Storm Uri and ~~the various governmental, business and consumer responses~~was forced to this pandemic, did not have a significant impact on our results in the first quarter of 2020. During the first quarter of 2020, the Epoxy business had manufacturing plant closures and operating reductions in Asiahalt production due to ~~COVID-19 which reduced first quarter 2020 Epoxy segment earnings~~the lack of electrical power, natural gas, and other raw materials. All of Olin’s Freeport operations were impacted. In addition, production at Olin’s Plaquemine, LA; St. Gabriel, LA; Oxford, MS; and McIntosh, AL facilities were also negatively impacted. As a result, by ~~approximately $3 million. These epoxy resin manufacturing plants~~February 18, 2021, Olin declared Force Majeure on all chemical product shipments from North America. As of March 31, 2021, our facilities had returned to ~~normal operations by the end of~~operation.

The first quarter ~~2020. All Olin manufacturing facilities worldwide are currently operating, with the exception of those undergoing planned maintenance turnarounds.~~

We have taken measures to protect the health and safety of our employees, work with our customers and suppliers to minimize potential disruptions and support our communities during this global pandemic. Our operations are among businesses that have been considered “essential” by government and public health authorities. We continue to safely maintain plant operations and focus on business continuity.

~~The~~2021 included a net pretax favorable impact of $99.9 million associated with Winter Storm Uri due to Olin’s customary financial hedges and contracts maintained to provide protection from rapid and dramatic changes in energy costs, partially offset by unabsorbed fixed manufacturing costs and storm-related maintenance costs.

Net income for the ~~various governmental,~~three months ended March 31, 2021 was $243.6 million, compared to net loss of $80.0 million for the comparable prior year period. The increase in results from the prior year was due to improved operating results across all our business ~~and consumer responses to the pandemic are expected to have a negative impact on the near-term demand for several of the products produced by our~~ segments.

Chlor Alkali Products and Vinyls ~~and Epoxy businesses. We continue to work with our customers, employees, suppliers and communities to address the impacts~~reported segment income of COVID-19 and we continue to assess possible implications to our business, supply chain and customers, and to take actions in an effort to mitigate adverse consequences. Our cash and cash equivalents as of March 31, 2020 were $194.5 million. We have no required bond repayments until August 2022.

Due to the likelihood of the deteriorating economic conditions in 2020, we have initiated several on-going actions that we believe will partially mitigate the impact of economic decline on our financial performance, but also enhance our position, financially and structurally, to take advantage of the eventual global economic recovery. Several of these actions and our liquidity resources are summarized below:

timing of cash receipts and enhance our cash position. The Receivables Financing Agreement and accounts receivable factoring arrangements do not impact our $2,000.0 million senior credit facility debt ratio covenants.

As we enter a period of economic uncertainty, we believe the steps we have taken and will continue to take to enhance our capital structure and liquidity have strengthened our ability to operate through the current conditions.

~~Net loss was $80.0~~$271.1 million for the three months ended March 31, ~~2020 compared to net~~2021. The first quarter 2021 segment income included a favorable impact of ~~$41.7~~$121.4 million ~~for the comparable prior year period. The decrease in results from the prior year was primarily~~associated with Winter Storm Uri due to ~~lower~~customary financial hedges and contracts maintained to provide protection from rapid and dramatic changes in energy costs, partially offset by unabsorbed fixed manufacturing costs and storm-related maintenance costs. Chlor Alkali Products and Vinyls segment results ~~primarily due to lower pricing. Partially offsetting the lower Chlor Alkali Products and Vinyls results~~without Winter Storm Uri were ~~higher Epoxy and Winchester segment results.~~

Chlor Alkali Products and Vinyls generated a segment loss of $34.3 million for the three months ended March 31, 2020. Chlor Alkali Products and Vinyls segment income was lower than in the comparable prior year period primarily due to lower caustic soda and ethylene dichloride (EDC) pricing and higher maintenance turnaround costs. The Chlor Alkali Products and Vinyls segment earnings were also negatively impacted by rail transportation issues in Canada, which reduced operating rates and ultimately shutdown our Canadian chlor alkali facility for ten days. Chlor Alkali Products and Vinyls segment income included depreciation and amortization expense of $118.5 million and $119.8 million for the three months ended March 31, 2020 and 2019, respectively.

During 2019, North America caustic soda price contract indices decreased $90 per ton and caustic soda export price indices decreased approximately $160 per metric ton. In the first quarter of 2020, North America caustic soda price contract indices decreased an additional $5 per ton and caustic soda export price indices increased approximately $15 per metric ton. During the first quarter of 2020, two caustic soda price increases were announced. The first announcement during February was an increase of $30 per ton and the second announcement during March was an increase of $60 per ton. An additional price increase of $80 per ton was announced in April 2020. These price increases are in the process of being implemented and while the extent to which these price increases are achieved is uncertain, the majority of the benefits, if realized, would impact second quarter and third quarter 2020 results.

Epoxy reported segment income of $11.7 million for the three months ended March 31, 2020. Epoxy segment income was higher than in the comparable prior year period primarily due to lower operating costs. The Epoxy segment earnings were negatively affected by 1) a force majeure declaration by a European phenol supplier during the first quarter, which reduced epoxy resin and epoxy resin precursor production, primarily at our Stade, Germany facility, and 2) Epoxy manufacturing plant closures and operating reductions in Asia due to COVID-19. Epoxy segment income included depreciation and amortization expense of $21.5 million and $26.5 million for the three months ended March 31, 2020 and 2019, respectively.

~~Winchester reported segment income of $10.5 million for the three months ended March 31, 2020. Winchester segment income was~~ higher than in the comparable prior year period primarily due to higher ~~sales volumes~~pricing, primarily ethylene dichloride (EDC), vinyl chloride monomer (VCM), chlorine and chlorinated organics. The segment results also improved due to lower costs, ~~primarily commodity~~including raw materials and ~~other material~~operating costs. ~~These improvements were partially offset by $2.8 million of transition costs related to the U.S. Army Lake City ammunition facility contract. Winchester~~Chlor Alkali Products and Vinyls segment ~~income~~results included depreciation and amortization expense of ~~$5.0~~$115.8 million and ~~$4.9~~$118.5 million for the three months ended March 31, ~~2020~~2021 and ~~2019,~~2020, respectively.

Epoxy reported segment income of $65.2 million for the three months ended March 31, 2021. The first quarter 2021 segment results included an unfavorable impact of $21.5 million associated with Winter Storm Uri due to unabsorbed fixed manufacturing costs and storm-related maintenance costs. Epoxy segment results without Winter Storm Uri were higher than in the comparable prior year period primarily due to higher product prices, partially offset by higher raw materials costs, primarily benzene and propylene. Epoxy segment results included depreciation and amortization expense of $22.1 million and $21.5 million for the three months ended March 31, 2021 and 2020, respectively.

Winchester reported segment income of $85.1 million for the three months ended March 31, 2021. On October 1, 2020, Winchester assumed full management and operational control of the Lake City U.S. Army Ammunition Plant (Lake City) in Independence, MO. Winchester segment results were higher than in the comparable prior year period primarily due to higher volumes, which includes ammunition produced at Lake City, and higher commercial ammunition pricing. Winchester segment results included depreciation and amortization expense of $5.6 million and $5.0 million for the three months ended March 31, 2021 and 2020, respectively.

On March 31, 2021, Olin redeemed $315.0 million of the outstanding 10.00% senior notes due 2025 (2025 Notes). The 2025 Notes were redeemed at 105.0% of the principal amount of the 2025 Notes, resulting in a redemption premium of $15.8 million. The 2025 Notes were redeemed by drawing $315.0 million of the Delayed Draw Term Loan along with utilizing $15.8 million of cash on hand.

redemption premium of $9.3 million. The outstanding 2025 Notes are expected to be redeemed by utilizing cash on hand.

Olin drove sequential pricing improvement in the first quarter of ~~2020. As of April 30,~~2021 for our chlorine and almost all chlorine derivatives, including epoxy resins. During 2021, we expect to continue to deliver ECU pricing improvement compared to 2020, all Olin manufacturing facilities worldwide are currently operating, with the exception of those undergoing planned maintenance turnarounds.

During 2021, productivity efforts are uncertain and unpredictable, including the duration and spread of the pandemic, its impact on capital and financial markets and any new information that may emerge concerning the severity of the virus, its spreadalso expected to other regions and the actions to contain the virus or treat its impact, among others. Though management is actively monitoring this situation, given the daily evolution of the COVID-19 outbreak, we are unable to estimate the full effects of the COVID-19 outbreak on our financial condition, liquidity, results of operations, suppliers, industry, and workforce.result in lower operating costs.

The demand outlook for our Chlor Alkali Products and Vinyls and Epoxy businesses is unclear. As a result of expected weaker customer demand and a high level of maintenance turnaround activity, we expect second quarter 2020 Chlor Alkali Products and Vinyls volumes to be meaningfully lower compared to first quarter 2020. In the second quarter, we also expect sequential improvement in caustic soda pricing and sequentially lower ethylene dichloride pricing. In the second quarter of 2020, the Epoxy businessWinchester 2021 segment income is expected to ~~face weaker~~improve from 2020 segment income of $92.3 million due to higher commercial product ~~demand from automotive~~pricing and ~~industrial coatings customers, in both Europe and North America.~~

~~We expect our~~increased sales volumes, which includes ammunition produced at Lake City. During 2020, Winchester segment results included transition costs related to ~~benefit from stronger commercial ammunition demand during the second quarter of 2020. We expect to begin to benefit from~~ the Lake City ~~U.S. Army Ammunition Plant~~ contract beginning in the fourth quarter. We expect to incur approximately $25 million in transition costs and $80 million associated with an initial working capital investment in 2020 for the Lake City Plant contract. The contract is expected to increase Winchester’s annual revenue by $450 million to $550 million and segment earnings by approximately $40 million to $50of $13.5 million.

Other Corporate and Unallocated costs in ~~2020~~2021 are expected to be ~~higher~~lower than the ~~$156.3~~$154.3 million in ~~2019,~~2020, primarily due to 2020 results including $73.9 million of costs associated with the Information Technology Project. The Information Technology Project was concluded in late 2020. Partially offsetting these lower costs in 2021 will be higher ~~management~~variable incentive ~~expense,~~costs, including mark-to-market adjustments on stock-based compensation expense. ~~Costs associated with the Information Technology Project in 2020 are expected to be comparable to 2019. The Information Technology Project will be substantially completed during 2020.~~

During ~~2020,~~2021, we anticipate environmental expenses ~~to be~~ in the ~~$25~~$20 million to ~~$30~~$25 million range compared to ~~$25.3~~$20.9 million in ~~2019, excluding the $4.8 million of insurance recoveries. We do not believe that there will be additional recoveries of environmental costs incurred and expensed in prior periods during~~ 2020.

We expect non-operating pension income in ~~2020~~2021 to be in the ~~$13~~$30 million to ~~$18~~$35 million range compared to ~~$16.3~~$18.9 million in ~~2019.~~2020. Based on our plan assumptions and estimates, we will not be required to make any cash contributions to our domestic qualified defined benefit pension plan in ~~2020.~~2021. We have several international qualified defined benefit pension plans for which we anticipate cash contributions of less than $5 million in ~~2020.~~2021.

In ~~2020,~~2021, we currently expect our capital spending to be in the ~~$250 million to $275~~$200 million range, ~~including the investment associated with the Information Technology Project of~~which would be approximately ~~$40 million.~~$100 million lower than 2020 levels.

Environmental investigatory and remediation activities spending was associated with former waste disposal sites and past manufacturing operations. Spending in ~~2020~~2021 for investigatory and remedial efforts, the timing of which is subject to regulatory approvals and other uncertainties, is estimated to be approximately ~~$17~~$19 million. Cash outlays for remedial and investigatory activities associated with former waste disposal sites and past manufacturing operations were not charged to income, but instead, were charged to reserves established for such costs identified and expensed to income in prior periods. Associated costs of investigatory and remedial activities are provided for in accordance with generally accepted accounting principles governing probability and the ability to reasonably estimate future costs. Our ability to estimate future costs depends on whether our investigatory and remedial activities are in preliminary or advanced stages. With respect to unasserted claims, we accrue liabilities for costs that, in our experience, we expect to incur to protect our interests against those unasserted claims. Our accrued liabilities for unasserted claims amounted to $9.0 million at March 31, ~~2020.~~2021. With respect to asserted claims, we accrue liabilities based on remedial investigation, feasibility study, remedial action and operation, maintenance and monitoring (OM&M) expenses that, in our experience, we expect to incur in connection with the asserted claims. Required site OM&M expenses are estimated and accrued in their entirety for required periods not exceeding 30 years, which reasonably approximates the typical duration of long-term site OM&M. Charges to income for investigatory and remedial efforts were material to our operating results in ~~2019~~2020 and may be material to our operating results in ~~2020.~~2021.

The condensed balance sheets included reserves for future environmental expenditures to investigate and remediate known sites amounting to ~~$139.1~~$147.2 million, ~~$139.0~~$147.2 million and ~~$125.5~~$139.1 million at March 31, ~~2020,~~2021, December 31, ~~2019~~2020 and March 31, ~~2019,~~2020, respectively, of which ~~$122.1~~$128.2 million, ~~$122.0~~$128.2 million and ~~$108.5~~$122.1 million, respectively, were classified as other noncurrent liabilities. These amounts do not take into account any discounting of future expenditures or any consideration of insurance recoveries or advances in technology. These liabilities are reassessed periodically to determine if environmental circumstances have changed and/or remediation efforts and our estimate of related costs have changed. As a result of these reassessments, future charges to income may be made for additional liabilities.

Steel Chemicals (a wholly owned subsidiary of Olin) and other caustic soda producers were named as defendants in six purported class action civil lawsuits filed March 22, 25 and 26, 2019 and April 12, 2019 in the U.S. District Court for the Western District of New York on behalf of the respective named plaintiffs and a putative class comprised of all persons and entities who purchased caustic soda in the U.S. directly from one or more of the defendants, their parents, predecessors, subsidiaries or affiliates at any time between October 1, 2015 and the present. Olin, K.A. Steel Chemicals and other caustic soda producers were also named as defendants in two purported class action civil lawsuits filed July 25 and 29, 2019 in the U.S. District Court for the Western District of New York on behalf of the respective named plaintiffs and a putative class comprised of all persons and entities who purchased caustic soda in the U.S. indirectly from distributors at any time between October 1, 2015 and the present. The other defendants named in the lawsuits are Occidental Petroleum Corporation, Occidental Chemical Corporation d/b/a OxyChem, Westlake Chemical Corporation, Shin-Etsu Chemical Co., Ltd., Shintech Incorporated, Formosa Plastics Corporation, and Formosa Plastics Corporation, U.S.A. The lawsuits allege the defendants conspired to fix, raise, maintain and stabilize the price of caustic soda, restrict domestic (U.S.) supply of caustic soda and allocate caustic soda customers. Plaintiffs seek an unspecified amount of damages and injunctive relief. We believe we have meritorious legal positions and will continue to represent our interests vigorously in this matter. Any losses related to this matter are not currently estimable because of unresolved questions of fact and law, but, if resolved unfavorably to Olin, could have a material adverse effect on our financial position, cash flows or results of operations.

We, and our subsidiaries, are defendants in various other legal actions (including proceedings based on alleged exposures to asbestos) incidental to our past and current business activities. As of March 31, 2020, December 31, 2019 and March 31, 2019, our condensed balance sheets included accrued liabilities for these other legal actions of $12.0 million, $12.4 million and $15.8 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 other legal actions will materially adversely affect our financial position, cash flows or results of operations. In connection with the October 5, 2015 acquisition of Dow’s U.S. Chlor Alkali and Vinyl, Global Chlorinated Organics and Global Epoxy businesses, the prior owner of the businesses retained liabilities related to litigation to the extent arising prior to October 5, 2015.

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.

The payment of cash dividends is subject to the discretion of our board of directors and will be determined in light of then-current conditions, including our earnings, our operations, our financial condition, our capital requirements and other factors deemed relevant by our board of directors. In the future, our board of directors may change our dividend policy, including the frequency or amount of any dividend, in light of then-existing conditions.

Liquidity and Other Financing Arrangements

Our principal sources of liquidity are from cash and cash equivalents, cash flow from operations and borrowings under our ~~Delayed Draw Term Loan, 2019~~ Senior Revolving Credit Facility, Receivables Financing Agreement and AR Facilities. Additionally, we believe that we have access to the high-yield debt and equity markets.

In 2021, we are targeting a reduction in our outstanding debt of approximately $1.0 billion using cash generated from operations. On April 14, 2021, Olin notified bondholders that we intend to redeem the remaining $185.0 million of the outstanding 2025 Notes. The 2025 Notes are expected to be redeemed at 105.0% of the principal amount of the 2025 Notes, resulting in a redemption premium of $9.3 million.

On January 15, 2021, Olin redeemed the remaining $120.0 million of the outstanding 2023 Notes. The 2023 Notes were redeemed at 102.438% of the principal amount of the 2023 Notes, resulting in a redemption premium of $2.9 million. The remaining 2023 Notes were redeemed by utilizing $122.9 million of cash on hand.

On February 24, 2021, we entered into a ~~new five-year, $2,000.0~~$1,615.0 million senior secured credit facility ~~which replaced the~~(Senior Secured Credit Facility) that amended our existing ~~$1,975.0~~$1,300.0 million senior secured credit facility. The ~~2019~~ Senior ~~Credit Facility will mature in July 2024. The 2019 Senior~~Secured Credit Facility includes a senior ~~unsecured~~ delayed-draw term loan facility with aggregate commitments of $315.0 million (Delayed Draw Term Loan ), a senior secured term loan facility with aggregate commitments of $500.0 million (2020 Term Loan and together with the Delayed Draw Term Loan, the Senior Secured Term Loans) and a senior secured revolving credit facility with aggregate commitments in an ~~aggregate principal~~ amount ~~of up~~equal to ~~$1,200.0 million and an~~ $800.0 million ~~senior unsecured revolving credit~~(Senior Revolving Credit Facility). The maturity date for the Senior Secured Credit Facility is July 16, 2024. The amendment modified the pricing grid for the Senior Secured Credit Facility by reducing applicable interest rates on the borrowings under the facility.

On March 30, 2021, Olin drew the entire $315.0 million of the Delayed Draw Term Loan. The ~~2019~~Senior Secured Term Loans include principal amortization amounts payable beginning June 30, 2021 at a rate of 1.25% per quarter through the end of 2022, 1.875% per quarter during 2023 and 2.50% per quarter thereafter until maturity.

The Senior Revolving Credit Facility includes a $100.0 million letter of credit subfacility. At March 31, ~~2020,~~2021, we had $799.6 million available under our $800.0 million ~~2019~~ Senior Revolving Credit Facility because we had issued $0.4 million of letters of credit. The Delayed Draw Term Loan Facility will be available on a delayed basis in up to three draws to be made on or prior to November 29, 2020. We expect the proceeds from the Delayed Draw Term Loan Facility will be used to redeem the 9.75% senior notes due 2023 and the 10.00% senior notes due 2025 on or about October 15, 2020.

Under the Senior Secured Credit Facility, we may select various floating-rate borrowing options. The actual interest rate paid on borrowings under the Senior Secured Credit Facility is based on a pricing grid which is dependent upon the net leverage ratio as calculated under the terms of the applicable facility for the prior fiscal quarter. The ~~facility~~Senior Secured Credit Facility includes various customary restrictive covenants, including restrictions related to the ratio of secured debt to earnings before interest expense, taxes, depreciation and amortization ~~(leverage~~(secured leverage ratio) and the ratio of earnings before interest expense, taxes, depreciation and amortization to interest expense (coverage ratio). The calculation of secured debt in our secured leverage ratio excludes borrowings under the Receivables Financing Agreement, up to a maximum of $250.0 million. As of March 31, 2021, the only secured borrowings included in the secured leverage ratio were $815.0 million for our Senior Secured Term Loans and $153.0 million for our Go Zone and Recovery Zone bonds. Compliance with these covenants is determined quarterly. We were in compliance with all covenants and restrictions under all our outstanding credit agreements as of March 31, ~~2020,~~2021, 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 secured 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 March 31, ~~2020,~~2021, there were no covenants or other restrictions that limited our ability to borrow.

The overall ~~decrease~~increase in cash for the three months ended March 31, ~~2020~~2021 primarily reflects our ~~dividend payments and capital spending,~~operating results, partially offset by ~~our borrowings under our Receivables Financing Agreement.~~debt repayments, capital spending, and dividends paid. We believe, based on current and projected levels of cash flow from our operations, together with our cash and cash equivalents on hand and the availability to borrow under our ~~2019~~ Senior Revolving Credit ~~Facility, Delayed Draw Term Loan~~ Facility, Receivables Financing Agreement and AR Facilities, we have sufficient liquidity to meet our short-term and long-term needs to make required payments of interest on our debt, fund our operating needs, working capital ~~the payment to Dow for our ethylene investment on or about the fourth quarter of 2020~~ and our capital expenditure requirements.

On April 26, 2018, our board of directors authorized a share repurchase program for the purchase of shares of common stock at an aggregate price of up to $500.0 million. This program will terminate upon the purchase of $500.0 million of our common stock. There were no shares repurchased for both the three months ended March 31, ~~2020. For the three months ended March 31, 2019, 0.6 million shares were repurchased~~2021 and ~~retired at a cost of $13.2 million.~~2020. As of March 31, ~~2020,~~2021, we had repurchased a total of $195.9 million of our common stock, representing 10.1 million shares, and $304.1 million of common stock remained authorized to be repurchased.

In connection with the Acquisition, Olin and Dow entered into arrangements for the long-term supply of ethylene by Dow to Olin, pursuant to which, among other things, Olin made upfront payments in order to receive ethylene at producer economics and for certain reservation fees and for the option to obtain additional future ethylene supply at producer economics. On February 27, 2017, we exercised the remaining option to reserve additional ethylene at producer economics from Dow. In

~~connection with the exercise of this option, we also secured~~We maintain a ~~long-term customer arrangement. As a result, an additional payment will be made to Dow that is not to exceed $493 million on or about the fourth quarter of 2020.~~

~~On July 16, 2019, our existing~~ $250.0 million Receivables Financing Agreement ~~was extended~~that is scheduled to mature July 15, ~~2022 and downsized to~~ ~~$10.0 million~~ with the option to expand (Receivables Financing Agreement). During the three months ended March 31, 2020, we amended the Receivables Financing Agreement to expand the borrowing capacity and borrowed $150.0 million. During April 2020, we expanded the facility and borrowed an additional $100.0 million.2022. The Receivables Financing Agreement includes a minimum borrowing requirement of 50% of the facility limit or available borrowing capacity, ~~or facility limit,~~ whichever is ~~greater, beginning on October 1, 2020.~~lesser. The administrative agent for our Receivables Financing Agreement is PNC Bank, National Association. 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 secured leverage covenant that is contained in the ~~$2,000.0~~$1,615.0 million senior secured credit facility. As of March 31, ~~2020, we had $150.0 million drawn and no additional borrowing capacity under the Receivables Financing Agreement. As of March 31, 2020, $345.2~~2021, $393.9 million of our trade receivables were pledged as collateral. As of March 31, 2021, we had $125.0 million drawn with $125.0 million of additional borrowing capacity available under the Receivables Financing Agreement. As of December 31, ~~2019~~2020 and March 31, ~~2019,~~2020, we had ~~zero~~$125.0 million and ~~$125.0~~$150.0 million, respectively, drawn under the Receivables Financing Agreement.

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 ~~$315.0~~$228.0 million and certain of our foreign subsidiaries may sell their accounts receivable up to a maximum of €35.3 million. We will continue to service the outstanding accounts sold. These receivables qualify for sales treatment under ASC 860 and, accordingly, the proceeds are included in net cash provided by operating activities in the condensed statements of cash flows. The gross amount of receivables sold for the three months ended March 31, 2021 and 2020 ~~and 2019~~ totaled ~~$262.0~~$312.0 million and ~~$134.9~~$262.0 million, respectively. The factoring discount paid under the AR Facilities is recorded as interest expense on the condensed statements of operations. The factoring discount was ~~$0.6~~$0.4 million and ~~$0.5~~$0.6 million for the three months ended March 31, ~~2020~~2021 and ~~2019,~~2020, respectively. The agreements are without recourse and therefore no recourse liability has been recorded as of March 31, ~~2020,~~2021, December 31, ~~2019~~2020 and March 31, ~~2019.~~2020. As of March 31, ~~2020,~~2021, December 31, ~~2019~~2020 and March 31, ~~2019, $68.9~~2020, $142.5 million, ~~$63.1~~$48.8 million and ~~$96.8~~$68.9 million, respectively, of receivables qualifying for sales treatment were outstanding and will continue to be serviced by us.

~~Cash flow from operations is variable as a result~~

Table of both the seasonal and the cyclical nature of our operating results, which have been affected by seasonal and economic cycles in many of the industries we serve, such as the vinyls, urethanes, bleach, ammunition and pulp and paper. Cash flow from operations is affected by changes in chlorine, caustic soda and EDC selling prices caused by the changes in the supply/demand balance of these products, resulting in the Chlor Alkali Products and Vinyls segment having significant leverage on our earnings and cash flow. For example, assuming all other costs remain constant, internal consumption remains approximately the same and we are operating at full capacity, a $10 selling price change per ton of chlorine equates to an approximate $10 million annual change in our revenues and pretax profit, a $10 selling price change per ton of caustic soda equates to an approximate $30 million annual change in our revenues and pretax profit, and a $0.01 selling price change per pound of EDC equates to an approximate $20 million annual change in our revenues and pretax profit.Contents

For the three months ended March 31, ~~2020,~~2021, cash provided by operating activities ~~decreased~~increased by ~~$152.2~~$299.0 million from the three months ended March 31, ~~2019,~~2020, primarily due to ~~a decrease~~an increase in operating ~~results.~~results, partially offset by working capital increases to support operations. For the three months ended March 31, ~~2020,~~2021, working capital increased ~~$100.5~~$204.3 million compared to an increase of ~~$87.6~~$100.5 million for the three months ended March 31, ~~2019.~~2020. The working capital increase during the first quarter reflects normal seasonal working capital growth.

For the ~~fourth quarter of 2019. During 2020, Olin expects to reduce working capital by approximately $150 million.~~three months ended March 31, 2021, our DSO improved from the comparable prior year period.

At March 31, ~~2020,~~2021, we had total letters of credit of ~~$71.0~~$88.6 million outstanding, of which $0.4 million were issued under our ~~2019~~ Senior Revolving Credit Facility. The letters of credit were used to support certain long-term debt, certain workers compensation insurance policies, certain plant closure and post-closure obligations, certain international payment obligations and certain international pension funding requirements.

Our current debt structure is used to fund our business operations. As of March 31, ~~2020,~~2021, we had long-term borrowings, including the current installment and finance lease obligations, of ~~$3,491.5~~$3,748.1 million, of which ~~$305.9~~$1,095.9 million ~~was~~were at variable rates. Included within long-term borrowings on the condensed balance sheets were deferred debt issuance costs, unamortized bond original issue discount and deferred losses on fair value interest rate swaps. Commitments from banks under our ~~2019~~ Senior Revolving Credit ~~Facility, Delayed Draw Term Loan~~ Facility, Receivables Financing Agreement and AR Facilities are additional sources of liquidity.

New Accounting ~~Standards~~Pronouncements

~~In March 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2020-04, “Facilitation~~Discussion of ~~the Effects of Reference Rate Reform on Financial Reporting” which creates a~~ new ~~topic, ASC 848 “Reference Rate Reform.” This update provides optional guidance to ease the potential~~ accounting burden associated with transition away from reference rates that are expected to be discontinued at the end of 2021, at which time financial institutions will no longer be required to report information that is currently used to determine the London Interbank Offered Rate (LIBOR) and other reference rates. This update allows companies to treat contract amendments to existing contracts for the purpose of establishing a new reference rate as continuations of those contracts without additional analysis, as long as the modification was made to establish a new reference rate. This update applies prospectively to contract modifications. The optional guidance was effective on March 12, 2020 andpronouncements can be ~~adopted beginning January~~referred to under Item 1, 2020 or any date thereafter until December 31, 2022, at which time the optional guidance can no longer be applied to contract amendments to existing contracts. We adopted the provisions of this update on January 1, 2020 and will apply this guidance prospectively to contract modifications that are entered into for the purpose of establishing a new reference rate. We are currently evaluating the prospective impact on our consolidated financial statements; however, for the three months ended March 31, 2020, the adoption of this update did not have a material impact on our consolidated financial statements.within Note 2, “Recent Accounting Pronouncements.”

In December 2019, the FASB issued ASU 2019-12, “Simplifying the Accounting for Income Taxes” which amends ASC 740 “Income Taxes” (ASC 740). This update is intended to simplify accounting for income taxes by removing certain exceptions to the general principles in ASC 740 and amending existing guidance to improve consistent application of ASC 740. This update is effective for fiscal years beginning after December 15, 2020 and interim periods within those fiscal years. The guidance in this update has various elements, some of which are applied on a prospective basis and others on a retrospective basis with earlier application permitted. We adopted this update on January 1, 2020 which did not have a material impact on our consolidated financial statements.

In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment” which amends ASC 350. This update will simplify the measurement of goodwill impairment by eliminating Step 2 from the goodwill impairment test. This update will require an entity to perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. The update does not modify the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. This update is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. The guidance in this update is applied on a prospective basis, with earlier application permitted. We adopted this update on January 1, 2020 which did not have a material impact on our consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments,” (ASU 2016-13) which amends ASC 326 “Financial Instruments—Credit Losses” (ASC 326). Subsequent to the issuance of ASU 2016-13, ASC 326 was amended by various updates that amend and clarify the impact and implementation of the aforementioned update. The new guidance introduces the current expected credit loss (CECL) model, which will require an entity to record an allowance for credit losses for certain financial instruments and financial assets, including trade receivables, based on expected losses rather than incurred losses. Under this update, on initial recognition and at each reporting period, an entity will be required to recognize an allowance that reflects the entity’s current estimate of credit losses expected to be incurred over the life of the financial instrument. This update is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. The guidance in this update has various elements, some of which are applied on a prospective basis and others on a retrospective basis, with earlier application permitted. We adopted this update on January 1, 2020 which did not have a material impact on our consolidated financial statements and related disclosures.

Item 3. Quantitative and Qualitative Disclosures about Market Risk.

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. As of March 31, ~~2020,~~2021, we maintained open positions on commodity contracts with a notional value totaling ~~$257.4~~$238.1 million ($~~174.6~~214.1 million at December 31, ~~2019~~2020 and ~~$168.6~~$257.4 million at March 31, ~~2019)~~2020). Assuming a hypothetical 10% increase in commodity prices which are currently hedged, as of March 31, ~~2020,~~2021, we would experience a ~~$25.7~~$23.8 million ($~~17.5~~21.4 million at December 31, ~~2019~~2020 and ~~$16.9~~$25.7 million at March 31, ~~2019)~~2020) increase in our cost of inventory purchased, which would be substantially offset by a corresponding increase in the value of related hedging instruments.

We transact business in various foreign currencies other than the USD which exposes us to movements in exchange rates which may impact revenue and expenses, assets and liabilities and cash flows. Our significant foreign currency exposure is

Table of Contents

denominated with European currencies, primarily the Euro, although exposures also exist in other currencies of Asia Pacific, Latin America, Middle East and Africa. For all derivative positions, we evaluated the effects of a 10% shift in exchange rates between those currencies and the USD, holding all other assumptions constant. Unfavorable currency movements of 10% would negatively affect the fair values of the derivatives held to hedge currency exposures by ~~$24.7~~$32.3 million. These unfavorable changes would generally have been offset by favorable changes in the values of the underlying exposures.

We are exposed to changes in interest rates primarily as a result of our investing and financing activities. Our current debt structure is used to fund business operations, and commitments from banks under our ~~2019~~ Senior Revolving Credit Facility, ~~Delayed Draw Term Loan,~~ Receivables Financing Agreement and AR Facilities are additional sources of liquidity. As of March 31, ~~2020,~~2021, December 31, ~~2019~~2020 and March 31, ~~2019,~~2020, we had long-term borrowings, including current installments and finance lease obligations, of ~~$3,491.5~~$3,748.1 million, ~~$3,340.8~~$3,863.8 million and ~~$3,193.3~~$3,491.5 million, respectively, of which ~~$305.9~~$1,095.9 million, ~~$155.9~~$780.9 million and ~~$773.9~~$305.9 million at March 31, ~~2020,~~2021, December 31, ~~2019~~2020 and March 31, ~~2019,~~2020, respectively, were issued at variable rates. Included within long-term borrowings on the condensed balance sheets were deferred debt issuance costs, unamortized bond original issue discount and deferred losses on fair value interest rate swaps.

Assuming no changes in the ~~$305.9~~$1,095.9 million of variable-rate debt levels from March 31, ~~2020,~~2021, we estimate that a hypothetical change of 100-basis points in the LIBOR interest rates would impact annual interest expense by ~~$3.1~~$11.0 million.

Our interest rate swaps ~~reduced~~increased interest expense by ~~$0.6~~$1.2 million and $0.1 million for the three months ended March 31, ~~2019.~~2021 and 2020, respectively.

If the actual changes in commodities, foreign currency, or interest pricing is substantially different than expected, the net impact of commodity risk, foreign currency risk, or interest rate risk on our cash flow may be materially different than that disclosed above.

We do not enter into any derivative financial instruments for speculative purposes.

Item 4. Controls and Procedures.

Our chief executive officer and our chief financial officer evaluated the effectiveness of our disclosure controls and procedures as of March 31, ~~2020~~.2021. Based on that evaluation, our chief executive officer and chief financial officer have concluded that, as of such date, our disclosure controls and procedures were effective to ensure that information Olin is required to disclose in the reports that it files or submits with the SEC under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the Commission’s rules and forms, and to ensure that information we are required to disclose in such reports is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate to allow timely decisions regarding required disclosure.

There have been no changes in our internal control over financial reporting that occurred during the quarter ended March 31, ~~2020,~~2021, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Item 1A. Risk Factors.

The following is a supplement and update to the risk factors in Part I, Item 1A “Risk Factors,” in our Annual Report on Form 10-K for the year ended December 31, 2019. The following factors should be considered in evaluating Olin and our business. All of our forward-looking statements should be considered in light of these factors. Additional risks and uncertainties that we are unaware of or that we currently deem immaterial also may become important factors that affect us.Not Applicable.

2019 Novel Coronavirus (COVID-19) Pandemic—The COVID-19 pandemic and the global response to the pandemic could have a material adverse impact on our business, financial condition, or results of operations.

The COVID-19 pandemic and the various governmental, business, and consumer responses to the pandemic are having and could continue to have negative impacts on our business. These impacts could include plant closures or operating reductions, volatility and decrease in demand for our products, and supply chain interruptions. Furthermore, the pandemic and responses thereto could cause or contribute to certain of the risks and uncertainties described in our Form 10-K, including Sensitivity to Global Economic Conditions and Cyclicality, Cyclical Pricing Pressure, Raw Materials, Credit Facility, and Credit and Capital Market Conditions. During the first quarter 2020, the Epoxy business had manufacturing plant closures and operating reductions in Asia due to COVID-19. Our customers could reduce production rates or curtail production and we could experience additional temporary plant closures and operating reductions due to the COVID-19 crisis. These impacts could become more widespread or prolonged as the pandemic continues. The extent to which COVID-19 impacts our results will depend on future developments that are out of our control and highly uncertain, including the severity and duration of the pandemic, the domestic and international actions that are taken in response, and the extent and severity of any resulting economic or industry downturn.
