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, including allyl chloride, epichlorohydrin, liquid epoxy resins, solid epoxy resins and downstream products such as differentiated 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 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. Certain reclassifications were made to prior year amounts to conform to the 2020 presentation.

NOTE 2. RESTRUCTURING CHARGES

On December 11, 2019, we announced that we had made the decision to permanently close a chlor alkali plant with a capacity of 230,000 tons and our vinylidene chloride (VDC) production facility, both in Freeport, TX. The VDC facility was closed during fourth quarter 2020. The related chlor alkali plant closure is expected to be completed in second quarter 2021. For the three and nine months ended September 30, 2020, we recorded pretax restructuring charges of $0.3 million and $0.8 million, respectively, for facility exit costs related to these actions. We expect to incur additional restructuring charges through 2024 of approximately $50 million related to these actions.

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 and nine months ended September 30, 2019, we recorded pretax restructuring charges of $0.1 million and $0.4 million, respectively, for facility exit costs and lease and other contract termination costs related to this action. For the nine months ended September 30, 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. 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 September 30, 2020 and 2019, we recorded pretax restructuring charges of $1.0 million and $4.8 million, respectively, for facility exit costs, employee severance and related benefit costs and lease and other contract termination costs related to these actions. For the nine months ended September 30, 2020 and 2019, we recorded pretax restructuring charges of $3.9 million and $10.9 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 2021 of approximately $4 million related to these capacity reductions.

NOTE 3. ACCOUNTS RECEIVABLES

On July 16, 2019, our existing $250.0 million Receivables Financing Agreement was extended to July 15, 2022 and downsized to $10.0 million with the option to expand (Receivables Financing Agreement). During the nine months ended September 30, 2020, we amended the Receivables Financing Agreement to expand the borrowing capacity to $250.0 million. The Receivables Financing Agreement includes a minimum borrowing requirement of 50% of the facility limit or available borrowing capacity, whichever is lesser, beginning on October 1, 2020. 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 $1,300.0 million senior secured credit facility. As of September 30, 2020, $325.1 million of our trade receivables were pledged as collateral. As of September 30, 2020, we had

$125.0 million drawn with $115.8 million of additional borrowing capacity available under the Receivables Financing Agreement. As of both December 31, 2019 and September 30, 2019, we had zero drawn under the Receivables Financing Agreement.

Balance at end of period	$	93.1		$	107.4

The factoring discount paid under the AR Facilities is recorded as interest expense on the condensed statements of operations. The factoring discount was $0.2 million and $0.8 million for the three months ended September 30, 2020 and 2019, respectively, and $1.2 million and $2.3 million for the nine months ended September 30, 2020 and 2019, respectively. The agreements are without recourse and therefore no recourse liability had been recorded as of September 30, 2020, December 31, 2019, or September 30, 2019.

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 through an allowance for doubtful accounts receivable 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 group receivables together for purposes of estimating credit losses when customers have similar risk characteristics; otherwise, the estimation is performed on the individual receivable.

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:

Provisions charged	0.7			1.1

Balance at end of period	$	12.1		$	11.9

Provisions charged to operations were zero and $0.2 million for the three months ended September 30, 2020 and 2019, respectively.

NOTE 5. INVENTORIES

Inventories consisted of the following:



	September 30, 2020			December 31, 2019			September 30, 2019
	($ in millions)
Supplies	$	107.6		$	105.6		$	99.4
Raw materials	86.4			69.2			60.9
Work in process	96.3			120.9			123.1
Finished goods	363.8			449.5			474.9
	654.1			745.2			758.3
LIFO reserve	(45.7		)	(49.5		)	(57.6		)
Inventories, net	$	608.4		$	695.7		$	700.7

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 September 30, 2020 reflect certain estimates relating to inventory quantities and costs at December 31, 2020. The replacement cost of our inventories would have been approximately $45.7 million, $49.5 million and $57.6 million higher than reported at September 30, 2020, December 31, 2019 and September 30, 2019, respectively.

NOTE 6. OTHER ASSETS

Included in other assets were the following:

Supply contracts	$	1,129.7	$	1,112.6	$	1,122.0
Other	47.3		56.5		48.1
Other assets	$	1,177.0	$	1,169.1	$	1,170.1

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 of $11.2 million for the nine months ended September 30, 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 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.

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 was made to Dow of $461.0 million during the second quarter of 2020. The original liability was discounted and recorded at present value as of March 31, 2017. The discount amount of $40.9 million was recorded as interest expense from inception through March 31, 2020. For the three months ended September 30, 2019, $4.4 million, and for the nine months ended September 30, 2020 and 2019, $4.0 million and $12.6 million, respectively, of interest expense was recorded for accretion on the 2020 payment liability discount.

Amortization expense of $9.4 million for both the three months ended September 30, 2020 and 2019 and $28.2 million for both the nine months ended September 30, 2020 and 2019 was recognized within cost of goods sold related to our long-term

supply contracts and is reflected in depreciation and amortization on the condensed statements of cash flows. The long-term supply contracts are monitored for impairment each reporting period.

During the nine months ended September 30, 2020, a payment of $75.8 million was made associated with the resolution of a dispute over the allocation to Olin of certain capital costs incurred at our Plaquemine, LA site after the Closing Date of the Acquisition.

NOTE 7. GOODWILL AND INTANGIBLE ASSETS

Changes in the carrying value of goodwill were as follows:



	Chlor Alkali Products and Vinyls			Epoxy			Total
	($ in millions)
Balance at January 1, 2019	$	1,832.6		$	287.0		$	2,119.6
Foreign currency translation adjustment	(0.4		)	(0.1		)	(0.5		)
Balance at September 30, 2019	$	1,832.2		$	286.9		$	2,119.1
Balance at January 1, 2020	$	1,832.7		$	287.0		$	2,119.7

Foreign currency translation adjustment	0.2			—			0.2
Balance at September 30, 2020	$	1,275.3		$	144.8		$	1,420.1

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 first quarter of 2020, our market capitalization declined significantly compared to the fourth quarter of 2019. Over the same period, the equity value of our peer group companies and the overall U.S. stock market also declined significantly amid market volatility. These declines were driven by the uncertainty surrounding the outbreak of the 2019 Novel Coronavirus (COVID-19) global pandemic and other macroeconomic events impacting the various industries in which Olin and our peers participate. Additionally, the various governmental, business and consumer responses to the pandemic were expected to have a negative impact on the near-term demand for several of the products produced by our Chlor Alkali Products and Vinyls and Epoxy businesses. The full extent and duration of the impact of COVID-19 on our operations and financial performance was unknown at the time. As a result of these events, we identified triggering events associated with a significant overall decrease in our stock price, a significant adverse change in the business climate and a significant reduction in near-term cash flow projections and 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.

Throughout the second and third quarters of 2020, the spread of the COVID-19 pandemic and the associated response has caused significant disruptions in the U.S. and global economies, resulting in the disruption of the supply and demand fundamentals of our Chemicals businesses. The various governmental, business and consumer responses to the pandemic continued to negatively impact the demand for several of the products produced by our Chlor Alkali Products and Vinyls and Epoxy businesses resulting in lower volumes and pricing during 2020 compared to 2019. Due to these factors, the triggering events identified in the first quarter associated with a significant adverse change in the business climate and a significant adverse reduction in near-term cash flow projections have persisted during 2020. Throughout the second and third quarters of 2020, the equity value of our peer group companies and the overall U.S. stock market improved significantly while Olin’s stock price remained low. During the three months ended September 30, 2020, we identified a triggering event associated with a sustained significant overall decrease in our stock price. As a result, we performed an updated quantitative goodwill impairment test during the third quarter of 2020. We used a discounted cash flow approach to develop the estimated fair value of our reporting units.

Table of Contents

Fair value determinations require considerable judgment and are sensitive to changes in underlying assumptions, estimates and market factors. 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, in part 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. Also factoring into the discount rate was a market participant’s perceived risk (such as the company specific risk premium) in the valuation implied by the sustained reduction in our stock price.

The discounted cash flow analysis requires estimates, assumptions and judgments about future events. Our analysis uses our internally generated long-range plan. Specifically, the assumptions in our long-range plan about terminal growth rates, forecasted capital expenditures and changes in future working capital requirements are used 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.

As a further indicator that each reporting unit has been valued appropriately using a discounted cash flow model, the aggregate fair value of all reporting units is reconciled to the total market value of Olin. Due to the sustained decline in our stock price, the decrease in the value of our reporting units reflects a market participant’s perceived risk in the valuation implied by the sustained reduction in our stock price. As a result of this assessment, the carrying values of our Chlor Alkali Products and Vinyls and Epoxy reporting units exceeded the fair values which resulted in pre-tax goodwill impairment charges of $557.6 million and $142.2 million, respectively. The goodwill impairment charge was calculated as the amount that the carrying value of the reporting unit, including any goodwill, exceeded its fair value and therefore the carrying value of our reporting units equal their fair value upon completion of the goodwill impairment test.

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. If our assumptions regarding future performance are not achieved, or if our stock price experiences further sustained declines, we may be required to record additional goodwill impairment charges in 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.

NOTE 8. EARNINGS PER SHARE

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

The computation of dilutive shares does not include 10.3 million and 7.4 million shares for the three months ended September 30, 2020 and 2019, respectively, and 10.3 million and 7.2 million shares for the nine months ended September 30, 2020 and 2019, respectively, as their effect would have been anti-dilutive.

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 (credited) to income, which are included in costs of goods sold, were as follows:



	Three Months Ended September 30,					Nine Months Ended September 30,
	2020		2019			2020		2019
	($ in millions)
Provisions charged (credited) to income	$	12.5	$	(0.8	)	$	17.9	$	23.0
Recoveries for costs incurred and expensed	—		—			—		(4.8		)
Environmental expense (income)	$	12.5	$	(0.8	)	$	17.9	$	18.2

Provisions charged (credited) to income for the nine months ended September 30, 2019 include $4.8 million of recoveries associated with resolving outstanding third party claims against the proceeds from a 2018 environmental insurance settlement. The condensed balance sheets included reserves for future environmental expenditures to investigate and remediate known sites amounting to $146.7 million, $139.0 million and $140.1 million at September 30, 2020, December 31, 2019 and September 30, 2019, respectively, of which $129.7 million, $122.0 million and $123.1 million, respectively, were classified as other noncurrent liabilities.

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 fourth quarter 2020 or first quarter 2021. 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 results of operations.

Olin, K.A. 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 September 30, 2020, December 31, 2019 and September 30, 2019, our condensed balance sheets included accrued liabilities for these other legal actions of $13.0 million, $12.4 million and $13.2 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.

NOTE 11. SHAREHOLDERS’ EQUITY

On August 5, 2019, we entered into an accelerated share repurchase (ASR) agreement with Goldman Sachs & Co. LLC (Goldman Sachs), a third-party financial institution, to repurchase $100.0 million of Olin’s common stock. This transaction qualified for treatment as an equity contract. Under this agreement, Olin paid $100.0 million to Goldman Sachs and received an initial delivery of 4.3 million shares in August 2019. The transaction had not settled as of September 30, 2019; however, upon settlement of the agreement in October 2019, we received 1.4 million additional shares which resulted in a total of 5.7 million shares repurchased under this ASR agreement.

There were no shares repurchased for the nine months ended September 30, 2020. For the nine months ended September 30, 2019, 6.0 million shares were repurchased and retired at a cost of $135.6 million. As of September 30, 2020, 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.

We issued less than 0.1 million and 0.1 million shares representing stock options exercised for the nine months ended September 30, 2020 and 2019, respectively, with a total value of $0.5 million and $1.5 million, respectively.

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



	Three Months Ended September 30,					Nine Months Ended September 30,
	2020		2019			2020			2019
	($ in millions)
Stock-based compensation	$	3.4	$	4.2		$	9.7		$	8.5
Mark-to-market adjustments	0.6		(1.4		)	(2.5		)	(1.0		)
Total expense	$	4.0	$	2.8		$	7.2		$	7.5

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 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.

NOTE 14. DEBT

On May 19, 2020, Olin issued $500.0 million aggregate principal amount of 9.50% senior notes due June 1, 2025 (2025 Notes). The 2025 Notes were issued at 99.5% of par value, the discount from which is included within long-term debt in the condensed balance sheets. Interest on the 2025 Notes is payable semi-annually beginning on December 1, 2020. Proceeds from the 2025 Notes were used for general corporate purposes.

On May 8, 2020, we entered into a $1,300.0 million senior secured credit facility (Senior Secured Credit Facility) that amended our existing five-year, $2,000.0 million senior credit facility. The Senior Secured Credit Facility includes a senior secured delayed-draw term loan facility with aggregate commitments of $500.0 million (Delayed Draw Term Loan Facility) and a senior secured revolving credit facility with aggregate commitments in an amount equal to $800.0 million (Senior Revolving Credit Facility). The maturity date for the Senior Secured Credit Facility is July 16, 2024. The amendment modified the financial covenants of the Senior Secured Credit Facility to be less restrictive and expanded the permitted use of proceeds of the Delayed Draw Term Loan Facility to include general corporate purposes.

The amendment also requires that the obligations under the Senior Secured Credit Facility be guaranteed by certain of our domestic subsidiaries, which are also guarantors of Olin’s outstanding notes, with the exception of the $200.0 million senior notes due 2022. The obligations under the Senior Secured Credit Facility are also secured by liens on substantially all of Olin’s and the subsidiary guarantors’ personal property (Collateral), other than certain principal properties and capital stock of subsidiaries, and subject to certain other exceptions. The amendment provides that substantially all guarantees under the Senior Secured Credit Facility and liens on the Collateral will be released automatically when our net leverage ratio is below 3.50 to 1.00 for two consecutive fiscal quarters.

The Delayed Draw Term Loan Facility is available on a delayed basis in up to three draws to be made on or prior to November 29, 2020. The Delayed Draw 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

Table of Contents

for the following year and to 10.0% per annum for the last two years. The Senior Revolving Credit Facility includes a $100.0 million letter of credit subfacility. At September 30, 2020, we had $799.6 million available under our $800.0 million Senior Revolving Credit Facility because we had issued $0.4 million of letters of credit.

For the nine months ended September 30, 2020, we recognized interest expense of $1.6 million for the write-off of unamortized deferred debt issuance costs related to the reduction of commitments under the Senior Secured Credit Facility. For the nine months ended September 30, 2020, we paid debt issuance costs of $9.9 million for the issuance of the 2025 Notes and amendments to our Senior Secured Credit Facility and Receivables Financing Agreement.

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 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 (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 September 30, 2020, the only secured borrowings included in the secured leverage ratio were $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 September 30, 2020, 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 September 30, 2020, there were no covenants or other restrictions that limited our ability to borrow.

Subsequent Event

On October 15, 2020, Olin redeemed $600.0 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 $14.6 million. The 2023 Notes were redeemed by drawing $500.0 million of the Delayed Draw Term Loan Facility along with utilizing $114.6 million of 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 September 30, 2020 and 2019 was $6.5 million and $6.9 million, respectively, and for the nine months ended September 30, 2020 and 2019 was $21.5 million and $23.2 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 September 30, 2020 and 2019 were $0.8 million and $4.0 million, respectively, and for the nine months ended September 30, 2020 and 2019 were $2.3 million and $11.9 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.

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.

Table of Contents

Our domestic qualified defined benefit pension plan provides that if, within three years following a change of control of Olin, any corporate action is taken or filing made in contemplation of, among other things, a plan termination or merger or other transfer of assets or liabilities of the plan, and such termination, merger, or transfer thereafter takes place, plan benefits would automatically be increased for affected participants (and retired participants) to absorb any plan surplus (subject to applicable collective bargaining requirements).

We also provide certain postretirement healthcare (medical) and life insurance benefits for eligible active and retired domestic employees. The healthcare plans are contributory with participants’ contributions adjusted annually based on medical rates of inflation and plan experience.

We made cash contributions to our international qualified defined benefit pension plans of $1.3 million and $0.7 million for the nine months ended September 30, 2020 and 2019, respectively.

NOTE 17. INCOME TAXES

The effective tax rate for the three months ended September 30, 2020 included a benefit associated with prior year tax positions and an expense from a net increase in the valuation allowance related to foreign tax credits. These factors resulted in a net $1.7 million tax expense. For the three months ended September 30, 2020, a tax benefit of $10.8 million was recognized associated with the $699.8 million goodwill impairment charge. After giving consideration to these items, including the goodwill impairment charge on Olin’s loss before taxes, the effective tax rate for the three months ended September 30, 2020 of 14.0% was lower than the 21% U.S. federal statutory rate primarily due to foreign income inclusions and a net increase in the valuation allowance related to losses in foreign jurisdictions partially offset by state taxes, foreign income taxes and favorable permanent salt depletion deductions. The effective tax rate for the three months ended September 30, 2019 included a benefit associated with the finalization of the Internal Revenue Service (IRS) review of years 2013 to 2015 U.S. income tax claims, a benefit associated with stock-based compensation, a benefit associated with prior year tax positions, a benefit from foreign tax law changes, a benefit from the remeasurement of deferred taxes due to a decrease in our state effective tax rates, an expense from a change in tax contingencies and an expense from a net increase in the valuation allowance related to state deferred tax assets. These factors resulted in a net $24.0 million tax benefit. After giving consideration to these items, the effective tax rate for the three months ended September 30, 2019 of 53.9% was higher than the 21% U.S. federal statutory rate,

Table of Contents

primarily due to state taxes, foreign income taxes and 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.

The effective tax rate for the nine months ended September 30, 2020 included a benefit associated with prior year tax positions, an expense associated with stock-based compensation, an expense from a net increase in the valuation allowance related to foreign tax credits and an expense from a change in tax contingencies. These factors resulted in a net $2.8 million tax expense. For the nine months ended September 30, 2020, a tax benefit of $10.8 million was recognized associated with the $699.8 million goodwill impairment charge. After giving consideration to these items, including the goodwill impairment charge on Olin’s loss before taxes, the effective tax rate for the nine months ended September 30, 2020 of 23.3% 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 nine months ended September 30, 2019 included a benefit associated with the finalization of the IRS review of years 2013 to 2015 U.S. income tax claims, a benefit associated with stock-based compensation, a benefit associated with prior year tax positions, a benefit from foreign tax law changes, a benefit from the remeasurement of deferred taxes due to a decrease in our state effective tax rates, a benefit from a net decrease in the valuation allowance related to state deferred tax assets and an expense from a change in tax contingencies. These factors resulted in a net $24.3 million tax benefit. After giving consideration to these items, the effective tax rate for the nine months ended September 30, 2019 of 42.2% was higher than the 21% U.S. federal statutory rate primarily due to state taxes, foreign income taxes and 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.

As of September 30, 2020, we had $22.7 million of gross unrecognized tax benefits, which would have a net $22.6 million impact on the effective tax rate, if recognized. As of September 30, 2019, we had $22.3 million of gross unrecognized tax benefits, of which $21.8 million would have impacted the effective tax rate, if recognized. The amount of unrecognized tax benefits was as follows:



	September 30,
	2020			2019
	($ in millions)
Balance at beginning of year	$	22.8		$	33.8
Increases for prior year tax positions	2.1			1.6
Decreases for prior year tax positions	(3.5		)	(14.3		)
Increases for current year tax positions	1.3			1.4
Settlements with taxing authorities	—			(0.2		)
Balance at end of period	$	22.7		$	22.3

As of September 30, 2020, we believe it is reasonably possible that our total amount of unrecognized tax benefits will decrease by approximately $3.8 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.

Table of Contents

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:



	Tax Years
U.S. federal income tax	2016 - 2019
U.S. state income tax	2006 - 2019
Canadian federal income tax	2012 - 2019

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 September 30, 2020, we had outstanding forward contracts to buy foreign currency with a notional value of $186.1 million and to sell foreign currency with a notional value of $127.7 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, we had outstanding forward contracts to buy foreign currency with a notional value of $140.6 million and to sell foreign currency with a notional value of $99.2 million. At September 30, 2019, we had outstanding forward contracts to buy foreign currency with a notional value of $105.6 million and to sell foreign currency with a notional value of $98.5 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:



	September 30, 2020		December 31, 2019		September 30, 2019
	($ in millions)
Natural gas	$	46.8	$	62.9	$	56.6
Ethane	38.2		51.5		48.3
Metals	118.5		60.2		62.7
Total notional	$	203.5	$	174.6	$	167.6

As of September 30, 2020, the counterparties to these commodity contracts were Wells Fargo Bank, N.A., Citibank, N.A., JPMorgan Chase Bank, National Association, Intesa Sanpaolo S.p.A. and Bank of America Corporation, all of which are major financial institutions.

We use cash flow hedges for certain raw material and energy costs such as copper, zinc, 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 September 30, 2020, we had open derivative contract positions through 2027. If all open futures contracts had been settled on September 30, 2020, we would have recognized a pretax gain of $24.2 million.

If commodity prices were to remain at September 30, 2020 levels, approximately $13.4 million of deferred gains, net of tax, would be reclassified into earnings during the next twelve months. The actual effect on earnings will be dependent on actual commodity prices when the forecasted transactions occur.

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 and nine months ended September 30, 2019, $1.8 million and $4.3 million, respectively, of income was recorded to interest expense on the accompanying condensed statements of operations related to these swap agreements.

Fair Value Hedges

We use interest rate swaps as a means of managing interest expense and floating interest rate exposure to optimal levels. For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in current earnings. We include the gain or loss on the hedged items (fixed-rate borrowings) in the same line item, interest expense, as the offsetting loss or gain on the related interest rate swaps.

In April 2016, we entered into interest rate swaps on $250.0 million of our underlying fixed-rate debt obligations, whereby we agreed to pay variable rates to the counterparties who, in turn, pay us fixed rates. In October 2016, we entered into interest rate swaps on an additional $250.0 million of our underlying fixed-rate debt obligations, whereby we agreed to pay variable rates to the counterparties who, in turn, pay us fixed rates. We designated the April 2016 and October 2016 interest rate swap agreements as fair value hedges 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. For the three and nine months ended September 30, 2019, $0.9 million and $2.6 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 September 30, 2020, December 31, 2019 and September 30, 2019, 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.

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.

Table of Contents

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 means of managing interest expense and floating interest rate exposure to optimal levels.

Commodity Contracts

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 fair value of our long-term debt was determined based on current market rates for debt of similar risk and maturities. The following table summarizes the fair value measurements of debt and the actual debt recorded on our condensed balance sheets:



	Fair Value Measurements								Amount recorded on balance sheets
	Level 1		Level 2		Level 3		Total		Amount recorded on balance sheets
	($ in millions)
Balance at September 30, 2020	$	—	$	3,925.7	$	153.0	$	4,078.7	$	3,960.7

Balance at September 30, 2019	—		3,399.6		153.0		3,552.6		3,340.1

Nonrecurring Fair Value Measurements

In addition to assets and liabilities that are recorded at fair value on a recurring basis, we record assets and liabilities at fair value on a nonrecurring basis as required by ASC 820. For the three months ended September 30, 2020, the carrying value of the Chlor Alkali Products and Vinyls and Epoxy reporting units’ goodwill was remeasured to fair value on a nonrecurring basis. The fair value of each reporting unit was calculated utilizing an income approach. The income approach uses a discounted cash flow model that requires various observable and nonobservable inputs, such as prices, volumes, expenses, capital expenditures, discount rates and projected long-term growth rates and terminal values. The resulting fair value Level 3 estimates were less than the reporting units’ carrying value which resulted in pre-tax goodwill impairment charge of $699.8 million. As part of our impairment analysis, the fair value of all reporting units was reconciled to the company’s market capitalization. See Note 7 “Goodwill and Intangibles” for additional information on the goodwill impairment. There were no other assets or liabilities measured at fair value on a nonrecurring basis as of September 30, 2020, December 31, 2019 and September 30, 2019.

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

Business Background

We are a leading vertically-integrated global manufacturer and distributor of chemical products and a leading 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.

Our Chlor Alkali Products and Vinyls segment is a commodity business where all supplier products are similar and price is the major supplier selection criterion. We have little or no ability to influence prices in the large, global commodity markets. 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 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 products manufactured by the Chlor Alkali Products and Vinyls segment. The Epoxy segment’s upstream and midstream products are predominately commodity markets. We have little or no ability to influence prices in these large, global commodity markets. 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.

Executive Summary

COVID-19

The 2019 Novel Coronavirus (COVID-19) global pandemic, and the various governmental, business and consumer responses to this pandemic, significantly impacted our results during 2020. 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 are following all federal, state and local health department guidelines and the costs associated with these safety procedures were not material. We continue to safely maintain plant operations and focus on business continuity. All Olin manufacturing facilities worldwide continue to operate, with the exception of those undergoing planned maintenance turnarounds.

The spread of the pandemic and the associated response has caused significant disruptions in the U.S. and global economies, resulting in the disruption of the supply and demand fundamentals of our Chemicals businesses. The various governmental, business and consumer responses to the pandemic negatively impacted the demand for several of the products produced by our Chlor Alkali Products and Vinyls and Epoxy businesses resulting in lower volumes and pricing. We are monitoring the changing business environment, volatility and heightened degree of uncertainty resulting from the response to COVID-19. At the current time, we are unable to fully determine its future impact on our business. We continue to work with our customers, employees, suppliers and communities to address the impacts 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.

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:


•	Our cash and cash equivalents as of September 30, 2020 were $282.7 million. We have no required bond repayments until August 2022.

•

In May 2020, we entered into a $1,300.0 million senior secured credit facility (Senior Secured Credit Facility) that amended our existing $2,000.0 million senior credit facility, which provides additional flexibility under our restrictive compliance covenants. The facility includes a senior secured revolving credit facility (Senior Revolving Credit Facility) with aggregate commitments in an amount equal to $800.0 million, of which we have $799.6 million available to us at September 30, 2020, and a senior secured delayed-draw term loan facility (Delayed Draw Term Loan Facility) with aggregate commitments of $500.0 million, which can be used for general corporate purposes. In October 2020, we drew the $500.0 million and used the proceeds to call a portion of the 9.75% senior notes due 2023 (2023 Notes).


•	In May 2020, we issued $500.0 million 9.50% senior notes due 2025 (2025 Notes). Proceeds from the 2025 Notes provided additional liquidity and were used for general corporate purposes.

•

During 2020, we amended our Receivables Financing Agreement to expand the borrowing capacity to $250.0 million and had borrowed $125.0 million as of September 30, 2020. We also have the ability to increase our accounts receivable factoring arrangements, which ultimately can accelerate the timing of cash receipts and enhance our cash position. The Receivables Financing Agreement and accounts receivable factoring arrangements do not impact our Senior Secured Credit Facility debt ratio covenants.


•	We are executing a strategy to improve our working capital and manage our balance sheet to maximize our financial flexibility. During 2020, Olin expects to reduce working capital by approximately $150 million, which includes an approximately $75 million investment in working capital to support Lake City operations.


•	We are forecasting capital spending to be in the $275 million range in 2020, which is approximately $110 million lower than prior year levels.

•

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) became law. The CARES Act provides for deferred payment of the employer portion of Social Security taxes through the end of 2020, with 50% of the deferred amount due December 31, 2021 and the remaining 50% due December 31, 2022. This is expected to provide us with approximately $20 million of additional liquidity during 2020.


•	We believe that we have access to both the high-yield debt and equity markets at this time.

We still believe there is a high degree of economic uncertainty in the global markets in which we participate and 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.

2020 Overview

Net loss was $736.8 million and $936.9 million for the three and nine months ended September 30, 2020, respectively, compared to net income of $44.2 million and $65.9 million, respectively, for the comparable prior year periods. The net loss for both the three and nine months ended September 30, 2020 included a goodwill impairment charge of $699.8 million. The negative results as compared to the prior year were also due to lower Chlor Alkali Products and Vinyls and Epoxy segments results, primarily due to lower pricing and volumes. Partially offsetting the lower Chemicals segment results were higher Winchester segment results.

Chlor Alkali Products and Vinyls reported segment income of $37.8 million and segment loss of $53.5 million for the three and nine months ended September 30, 2020, respectively. Chlor Alkali Products and Vinyls segment results were lower than in the comparable prior year periods primarily due to lower pricing, primarily caustic soda and ethylene dichloride (EDC), and lower volumes. These decreases were partially offset by lower costs, including raw materials and operating costs. Chlor Alkali Products and Vinyls segment results included depreciation and amortization expense of $112.1 million and $122.2 million for the three months ended September 30, 2020 and 2019, respectively, and $339.1 million and $360.8 million for the nine months ended September 30, 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. During the first half of 2020, North America caustic soda price contract indices increased $65 per ton and caustic soda export price indices increased approximately $130 per metric ton. During the third quarter of 2020, North America caustic soda price contract indices decreased $40 per ton and caustic soda export price indices decreased $110 per metric ton. During August 2020, a caustic soda price increase of $40 per ton and a chlorine price increase of $80 per ton were announced. In October 2020, an additional chlorine price increase of $100 per ton was announced. 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 fourth quarter 2020 and first quarter 2021 results.

Epoxy reported segment income of $14.9 million and $13.6 million for the three and nine months ended September 30, 2020, respectively. Epoxy segment results were lower than in the comparable prior year periods primarily due to lower product prices and volumes, partially offset by lower costs, primarily raw materials. Epoxy segment results included depreciation and amortization expense of $23.9 million and $26.9 million for the three months ended September 30, 2020 and 2019, respectively, and $67.0 million and $79.2 million for the nine months ended September 30, 2020 and 2019, respectively.

Winchester reported segment income of $21.0 million and $47.5 million for the three and nine months ended September 30, 2020, respectively. Winchester segment results were higher than in the comparable prior year periods primarily due to higher commercial ammunition volumes and higher product prices. These improvements were partially offset by $5.7 million and $12.3 million for the three and nine months ended September 30, 2020, respectively, of transition costs related to the Lake City U.S. Army Ammunition Plant (Lake City) contract. Winchester segment results included depreciation and amortization expense of $5.0 million and $5.2 million for the three months ended September 30, 2020 and 2019, respectively, and $14.7 million and $15.2 million for the nine months ended September 30, 2020 and 2019, respectively.

Subsequent Events

On October 1, 2020, Winchester assumed full management and operational control of the Lake City facility in Independence, Missouri. The U.S. Army selected Winchester to operate and manage the Lake City facility in September 2019. The contract has an initial term of seven years and may be extended by the U.S. Army for up to three additional years.

On October 15, 2020, Olin redeemed $600.0 million of the outstanding 9.75% senior notes due 2023. The 2023 Notes were redeemed at 102.438% of the principal amount of the 2023 Notes, resulting in a redemption premium of $14.6 million. The 2023 Notes were redeemed by drawing $500.0 million of the Delayed Draw Term Loan Facility along with utilizing $114.6 million of cash on hand.

Chlor Alkali Products and Vinyls sales decreased by $121.2 million, primarily due to lower caustic soda and EDC pricing and lower volumes. Epoxy sales decreased by $35.5 million, primarily due to lower product prices. Winchester sales increased by $17.7 million compared to the prior year, primarily due to increased commercial ammunition volumes and prices.

Gross margin decreased $88.8 million for the three months ended September 30, 2020 compared to the prior year. Chlor Alkali Products and Vinyls gross margin decreased by $76.6 million, primarily due to lower caustic soda and EDC pricing and lower volumes, partially offset by lower costs, including raw materials and operating costs. Epoxy gross margin decreased by $12.4 million, primarily due to lower product prices and an unfavorable product mix, partially offset by lower costs, primarily raw materials. Winchester gross margin increased by $12.9 million, primarily due to higher commercial ammunition volumes and prices. Gross margin was also impacted by higher environmental costs of $13.3 million. Gross margin as a percentage of sales decreased to 9% in 2020 from 14% in 2019.

Selling and administration expenses for the three months ended September 30, 2020 were $112.7 million, an increase of $1.9 million from the prior year. The increase was primarily due to transition costs relating to the Lake City contract of $5.7 million. These costs were partially offset by lower salaries and benefits of $2.5 million and lower travel-related expenses of $1.9 million. Selling and administration expenses for the three months ended September 30, 2020 and 2019 included costs associated with the Information Technology Project of $25.5 million and $24.5 million, respectively. Selling and administration expenses as a percentage of sales increased to 8% in 2020 from 7% in 2019.

Restructuring charges for the three months ended September 30, 2020 and 2019 of $1.3 million and $4.9 million, respectively, were primarily associated with the March 2016 closure of 433,000 tons of chlor alkali capacity across three separate locations.

Goodwill impairment includes non-cash pretax impairment charges of $557.6 million related to the Chlor Alkali Products and Vinyls segment and $142.2 million million related to the Epoxy segment.

Chlor Alkali Products and Vinyls

Three Months Ended September 30, 2020 Compared to Three Months Ended September 30, 2019

Chlor Alkali Products and Vinyls sales for the three months ended September 30, 2020 were $755.1 million compared to $876.3 million for the same period in 2019, a decrease of $121.2 million, or 14%. The sales decrease was primarily due to lower caustic soda and EDC pricing and lower volumes.

Chlor Alkali Products and Vinyls segment income was $37.8 million for the three months ended September 30, 2020 compared to $112.7 million for the same period in 2019, a decrease of $74.9 million, or 66%. The decrease in Chlor Alkali Products and Vinyls segment results was primarily due to lower product prices ($88.5 million), primarily caustic soda and EDC, and lower volumes ($23.8 million). Partially offsetting these decreases were lower raw material costs ($21.4 million) and lower maintenance turnaround and operating costs ($16.0 million). Chlor Alkali Products and Vinyls segment results included depreciation and amortization expense of $112.1 million and $122.2 million for the three months ended September 30, 2020 and 2019, respectively.

Nine Months Ended September 30, 2020 Compared to Nine Months Ended September 30, 2019

Chlor Alkali Products and Vinyls sales for the nine months ended September 30, 2020 were $2,166.2 million compared to $2,657.7 million for the same period in 2019, a decrease of $491.5 million, or 18%. The sales decrease was primarily due to lower caustic soda and EDC pricing and lower volumes.

Chlor Alkali Products and Vinyls segment loss was $53.5 million for the nine months ended September 30, 2020 compared to segment income of $303.8 million for the same period in 2019, a decrease of $357.3 million, or 118%. The decrease in Chlor Alkali Products and Vinyls segment results was primarily due to lower product prices ($346.8 million), primarily caustic soda and EDC, and lower volumes ($133.2 million), primarily caustic soda. Partially offsetting these decreases were lower raw material costs ($76.9 million) and lower maintenance turnaround and operating costs ($45.8 million). Chlor Alkali Products and Vinyls segment results included depreciation and amortization expense of $339.1 million and $360.8 million for the nine months ended September 30, 2020 and 2019, respectively.

Epoxy

Three Months Ended September 30, 2020 Compared to Three Months Ended September 30, 2019

Epoxy sales for the three months ended September 30, 2020 were $476.1 million compared to $511.6 million for the same period in 2019, a decrease of $35.5 million, or 7%. The sales decrease was primarily due to lower product prices ($62.6 million) partially offset by increased volumes ($25.8 million) and a favorable effect of foreign currency translation ($1.3 million).

Epoxy segment income was $14.9 million for the three months ended September 30, 2020 compared to $24.2 million for the same period in 2019, a decrease of $9.3 million, or 38%. The decrease in segment results was primarily due to lower product prices ($62.6 million) and an unfavorable product mix ($9.1 million), partially offset by lower raw material costs ($67.7 million), primarily benzene and propylene. Epoxy results were also negatively impacted by higher operating costs ($5.3 million). A significant percentage of our Euro denominated sales are of products manufactured within Europe. As a result, the impact of foreign currency translation on revenue is primarily offset by the impact of foreign currency translation on raw materials and manufacturing costs also denominated in Euros. Epoxy segment results included depreciation and amortization expense of $23.9 million and $26.9 million for the three months ended September 30, 2020 and 2019, respectively.

Nine Months Ended September 30, 2020 Compared to Nine Months Ended September 30, 2019

Epoxy sales for the nine months ended September 30, 2020 were $1,350.7 million compared to $1,554.4 million for the same period in 2019, a decrease of $203.7 million, or 13%. The sales decrease was primarily due to lower product prices ($170.6 million), decreased volumes ($16.8 million) and an unfavorable effect of foreign currency translation ($16.3 million).

Table of Contents

Epoxy segment income was $13.6 million for the nine months ended September 30, 2020 compared to $38.6 million for the same period in 2019, a decrease of $25.0 million, or 65%. The decrease in segment results was primarily due to lower product prices ($170.6 million) and decreased volumes and an unfavorable product mix ($23.8 million), partially offset by lower raw material costs ($142.3 million), primarily benzene and propylene. The Epoxy segment earnings were also negatively affected by a first quarter force majeure declaration by a European phenol supplier, which reduced epoxy resin and epoxy resin precursor production, and Epoxy manufacturing plant closures and operating reductions in Asia due to COVID-19 ($10.0 million). Epoxy results were also positively impacted by lower operating costs ($37.1 million). A significant percentage of our Euro denominated sales are of products manufactured within Europe. As a result, the impact of foreign currency translation on revenue is primarily offset by the impact of foreign currency translation on raw materials and manufacturing costs also denominated in Euros. Epoxy segment results included depreciation and amortization expense of $67.0 million and $79.2 million for the nine months ended September 30, 2020 and 2019, respectively.

Winchester

Three Months Ended September 30, 2020 Compared to Three Months Ended September 30, 2019

Winchester sales were $206.4 million for the three months ended September 30, 2020 compared to $188.7 million for the same period in 2019, an increase of $17.7 million, or 9%. The increase was due to higher ammunition sales to commercial customers ($21.4 million), partially offset by lower sales to military customers and law enforcement agencies ($3.7 million).

Winchester segment income was $21.0 million for the three months ended September 30, 2020 compared to $13.9 million for the same period in 2019, an increase of $7.1 million, or 51%. The increase in segment results was due to higher product pricing ($7.5 million) and increased sales volumes ($6.2 million). These improvements were partially offset by transition costs relating to the Lake City contract ($5.7 million) and higher operating costs ($0.9 million). Winchester segment income included depreciation and amortization expense of $5.0 million and $5.2 million for the three months ended September 30, 2020 and 2019, respectively.

Nine Months Ended September 30, 2020 Compared to Nine Months Ended September 30, 2019

Winchester sales were $587.0 million for the nine months ended September 30, 2020 compared to $510.8 million for the same period in 2019, an increase of $76.2 million, or 15%. The increase was due to higher ammunition sales to commercial customers ($74.1 million) and military customers and law enforcement agencies ($2.1 million).

Winchester segment income was $47.5 million for the nine months ended September 30, 2020 compared to $33.1 million for the same period in 2019, an increase of $14.4 million, or 44%. The increase in segment results was due to increased sales volumes ($16.8 million) and higher product pricing ($10.5 million). These improvements were partially offset by transition costs relating to the Lake City contract ($12.3 million) and higher operating costs ($0.6 million). Winchester segment income included depreciation and amortization expense of $14.7 million and $15.2 million for the nine months ended September 30, 2020 and 2019, respectively.

Corporate/Other

Three Months Ended September 30, 2020 Compared to Three Months Ended September 30, 2019

For the three months ended September 30, 2020, charges to income for environmental investigatory and remedial activities were $12.5 million compared to credits to income of $0.8 million for the three months ended September 30, 2019. These charges related primarily to expected future investigatory and remedial activities associated with past manufacturing operations and former waste disposal sites.

For the three months ended September 30, 2020, other corporate and unallocated costs were $43.7 million compared to $43.4 million for the three months ended September 30, 2019, an increase of $0.3 million. The increase was primarily due to higher legal and legal-related settlement expenses of $1.9 million, partially offset by a favorable effect of foreign currency translation of $1.2 million, lower salary and benefit costs of $0.8 million and lower travel-related expenses of $0.7 million. Other corporate and unallocated costs included costs associated with the implementation of the Information Technology Project for the three months ended September 30, 2020 and 2019 of $25.5 million and $24.5 million, respectively.

Table of Contents

Nine Months Ended September 30, 2020 Compared to Nine Months Ended September 30, 2019

For the nine months ended September 30, 2020, charges to income for environmental investigatory and remedial activities were $17.9 million compared to $18.2 million for the nine months ended September 30, 2019. These charges related primarily to expected future investigatory and remedial activities associated with past manufacturing operations and former waste disposal sites. The nine months ended September 30, 2019 includes a $4.8 million environmental insurance-related settlement gain.

For the nine months ended September 30, 2020, other corporate and unallocated costs were $112.2 million compared to $117.8 million for the nine months ended September 30, 2019, a decrease of $5.6 million. The decrease was primarily due to lower salary and benefit costs of $3.3 million, decreased management incentive expense of $2.2 million, which includes mark-to-market adjustments on stock-based compensation expense, lower travel-related expenses of $1.8 million and a favorable effect of foreign currency translation of $1.3 million. These decreases were partially offset by higher legal and legal-related settlement expenses of $2.6 million. Other corporate and unallocated costs included costs associated with the implementation of the Information Technology Project for the nine months ended September 30, 2020 and 2019 of $60.6 million and $60.1 million, respectively.

Outlook

The COVID-19 global pandemic, and the various governmental, business and consumer responses to this pandemic, significantly impacted our results during 2020. The spread of the pandemic and the associated response has caused significant disruptions in the U.S. and global economies, resulting in the disruption of the supply and demand fundamentals of our Chemicals businesses. We still believe there is a high degree of economic uncertainty in the global markets in which we participate and 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. We continue to work with our customers, employees, suppliers and communities to address the impacts of COVID-19 and we continue to assess possible implications to our business, supply chain and customers; however, we are unable to estimate the full effects of the COVID-19 outbreak on our financial condition, liquidity, results of operations, suppliers, industry, and work force.

The Chlor Alkali Products and Vinyls and Epoxy businesses remain challenged by the current economic conditions. Fourth quarter 2020 results for the Chemicals businesses are forecast lower than the third quarter 2020 due to expected lower volumes, partially offset by higher selling prices. In the fourth quarter, we expect sequential chlorine, epoxy resins, bleach, ethylene dichloride and chlorinated organics pricing improvement, partially offset by lower caustic soda pricing. We also expect volumes in fourth quarter 2020 to be sequentially lower than third quarter 2020 based on customer year-end inventory reductions.

We expect our Winchester segment to benefit from improved commercial ammunition pricing during the fourth quarter of 2020 compared to the third quarter of 2020. We also expect to benefit from the Lake City contract beginning in the fourth quarter. During 2020, we expect to incur approximately $15 million of transition costs and approximately $75 million associated with an initial working capital investment for the Lake City contract. The contract is expected to increase Winchester’s annual revenue by $450 million to $550 million and segment earnings by approximately $50 million.

Other Corporate and Unallocated costs in 2020 are expected to be comparable to the $156.3 million in 2019. Costs associated with the Information Technology Project in 2020 are also expected to be comparable to 2019. The Information Technology Project was substantially completed during the third quarter 2020.

During 2020, we anticipate environmental expenses to be in the $20 million to $25 million range compared to $25.3 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 to be approximately $18 million compared to $16.3 million in 2019. 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. We have several international qualified defined benefit pension plans for which we anticipate cash contributions of less than $5 million in 2020.

Table of Contents

In 2020, we currently expect our capital spending to be in the $275 million range, including the investment associated with the Information Technology Project of approximately $40 million. We expect 2020 depreciation and amortization expense to be in the $575 million range.

We currently believe the 2020 effective tax rate will be in the 25% range, excluding the impact of the third quarter 2020 goodwill impairment charge. We expect cash taxes could be a source of cash up to $10 million, as refunds from prior years’ U.S. federal taxes are partially offset by tax payments in foreign jurisdictions.

Environmental Matters

Environmental provisions charged (credited) to income, which are included in costs of goods sold, were as follows:

Foreign currency translation adjustments	(0.1		)	0.2
Balance at end of period	$	146.7		$	140.1

Environmental investigatory and remediation activities spending was associated with former waste disposal sites and past manufacturing operations. Spending in 2020 for investigatory and remedial efforts, the timing of which is subject to regulatory approvals and other uncertainties, is estimated to be approximately $14 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 September 30, 2020. 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 and may be material to our operating results in 2020.

Table of Contents

The condensed balance sheets included reserves for future environmental expenditures to investigate and remediate known sites amounting to $146.7 million, $139.0 million and $140.1 million at September 30, 2020, December 31, 2019 and September 30, 2019, respectively, of which $129.7 million, $122.0 million and $123.1 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.

Legal Matters and Contingencies

Olin, K.A. 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.

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.

Operating Activities

For the nine months ended September 30, 2020, cash provided by operating activities decreased by $111.3 million from the nine months ended September 30, 2019, primarily due to a decrease in operating results, partially offset by a decrease in the investment in working capital from the prior year. For the nine months ended September 30, 2020, working capital decreased $179.2 million compared to an increase of $79.9 million for the nine months ended September 30, 2019. Receivables decreased by $57.0 million from December 31, 2019, primarily as a result of lower sales during 2020. Inventories decreased by $90.5 million from December 31, 2019, primarily as a result of lower raw material costs and lower Winchester inventory due to improved commercial ammunition demand. Accounts payable and accrued liabilities increased $52.9 million as a result of specific actions taken by management to improve Olin’s working capital. During 2020, Olin expects to reduce working capital by approximately $150 million, which includes an approximately $75 million investment in working capital to support Lake City operations.

Investing Activities

Capital spending of $223.3 million for the nine months ended September 30, 2020 was $48.5 million lower than the corresponding period in 2019. For the total year 2020, we expect our capital spending to be in the $275 million range, which is expected to include $40 million for the Information Technology Project. For the total year 2020, depreciation and amortization expense is forecast to be in the $575 million range.

During 2017, we began a multi-year implementation of the Information Technology Project. The project standardizes business processes across the Chemicals businesses with the objective of maximizing cost effectiveness, efficiency and control across our global operations. The project is substantially completed. Total capital spending is forecast to be $220 million and associated expenses are forecast to be $190 million, including duplicate information technology costs being incurred during the transition. Our results for the nine months ended September 30, 2020 included $36.8 million of capital spending and $60.6 million of expenses associated with this project. Our results for the nine months ended September 30, 2019 included $53.3 million of capital spending and $60.1 million of expenses associated with this project.

For the nine months ended September 30, 2020, a payment of $461.0 million was made associated with long-term supply contracts to reserve additional ethylene at producer economics from Dow and a payment of $75.8 million was made associated

with the resolution of a dispute over the allocation to Olin of certain capital costs incurred at our Plaquemine, LA site after the Closing Date of the Acquisition.

On January 1, 2019, we sold our 9.1% limited partnership interest in Bay Gas for $20.0 million. The sale closed on February 7, 2019 which resulted in a gain of $11.2 million.

Financing Activities

For the nine months ended September 30, 2020, we had long-term debt borrowings, net of $620.7 million, which primarily included $497.5 million from the issuance of the 2025 Notes and $125.0 million under our Receivables Financing Agreement.

On May 19, 2020, Olin issued $500.0 million aggregate principal amount of 9.50% senior notes due June 1, 2025. The 2025 Notes were issued at 99.5% of par value, the discount from which is included within long-term debt in the condensed balance sheet. Interest on the 2025 Notes is payable semi-annually beginning on December 1, 2020. Proceeds from the 2025 Notes were used for general corporate purposes.

For the nine months ended September 30, 2019, we made long-term debt repayments of $744.1 million, which included $543.0 million related to the $1,375.0 million term loan facility and $150.0 million related to the Receivables Financing Agreement.

On July 16, 2019, Olin issued $750.0 million aggregate principal amount of 5.625% senior notes due August 1, 2029 (2029 Notes), which were registered under the Securities Act of 1933, as amended. Proceeds from the 2029 Notes were used to redeem the remaining balance of the $1,375.0 million term loan facility of $493.0 million and $150.0 million of the Receivables Financing Agreement.

For the nine months ended September 30, 2019, we repurchased and retired 6.0 million shares with a total cost of $135.6 million.

For the nine months ended September 30, 2020, we paid debt issuance costs of $9.9 million, primarily for the issuance of the 2025 Notes and amendments to our Senior Secured Credit Facility and Receivables Financing Agreement. For the nine months ended September 30, 2019, we paid debt issuance costs of $14.4 million, primarily for the issuance of the 2029 Notes and the 2019 refinancing of our senior credit facility.

The percent of total debt to total capitalization increased to 72.9% as of September 30, 2020 from 58.0% as of December 31, 2019 as a result of a higher level of debt outstanding and lower shareholders’ equity primarily resulting from the goodwill impairment charge.

In the first three quarters of 2020 and 2019, we paid a quarterly dividend of $0.20 per share. Dividends paid for the nine months ended September 30, 2020 and 2019, were $94.7 million and $98.5 million, respectively. On October 22, 2020, our board of directors declared a dividend of $0.20 per share on our common stock, payable on December 10, 2020 to shareholders of record on November 10, 2020.

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, 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.

Table of Contents

The 2023 Notes were redeemed by drawing $500.0 million of the Delayed Draw Term Loan Facility along with utilizing $114.6 million of cash on hand.

On May 19, 2020, Olin issued $500.0 million aggregate principal amount of 9.50% senior notes due June 1, 2025. The 2025 Notes were issued at 99.5% of par value, the discount from which is included within long-term debt in the condensed balance sheets. Interest on the 2025 Notes is payable semi-annually beginning on December 1, 2020. Proceeds from the 2025 Notes were used for general corporate purposes.

On May 8, 2020, we entered into a $1,300.0 million Senior Secured Credit Facility that amended our existing five-year, $2,000.0 million senior credit facility. The Senior Secured Credit Facility includes a Delayed Draw Term Loan Facility with aggregate commitments of $500.0 million and a Senior Revolving Credit Facility with aggregate commitments in an amount equal to $800.0 million. The maturity date for the Senior Secured Credit Facility is July 16, 2024. The amendment modified the financial covenants of the Senior Secured Credit Facility to be less restrictive and expanded the permitted use of proceeds of the Delayed Draw Term Loan Facility to include general corporate purposes.

The Senior Revolving Credit Facility includes a $100.0 million letter of credit subfacility. At September 30, 2020, we had $799.6 million available under our $800.0 million Senior Revolving Credit Facility because we had issued $0.4 million of letters of credit. The Delayed Draw Term Loan Facility is available on a delayed basis in up to three draws to be made on or prior to November 29, 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 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 (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 September 30, 2020, the only secured borrowings included in the secured leverage ratio were $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 September 30, 2020, 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 September 30, 2020, there were no covenants or other restrictions that limited our ability to borrow.

The overall increase in cash for the nine months ended September 30, 2020 primarily reflects our borrowings under the 2025 Notes and Receivables Financing Agreement and a decrease in working capital, partially offset by our payments under long-term supply contracts, 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 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 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 the nine months ended September 30, 2020. For the nine months ended September 30, 2019, 6.0 million shares were repurchased and retired at a cost of $135.6 million. As of September 30, 2020, we

Table of Contents

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 a long-term customer arrangement. As a result, an additional payment was made to Dow of $461.0 million during the second quarter of 2020.

On July 16, 2019, our existing $250.0 million Receivables Financing Agreement was extended to July 15, 2022 and downsized to $10.0 million with the option to expand (Receivables Financing Agreement). During the nine months ended September 30, 2020, we amended the Receivables Financing Agreement to expand the borrowing capacity to $250.0 million. The Receivables Financing Agreement includes a minimum borrowing requirement of 50% of the facility limit or available borrowing capacity, whichever is lesser, beginning on October 1, 2020. 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 Senior Secured Credit Facility. As of September 30, 2020, $325.1 million of our trade receivables were pledged as collateral. As of September 30, 2020, we had $125.0 million drawn with $115.8 million of additional borrowing capacity available under the Receivables Financing Agreement. As of December 31, 2019 and September 30, 2019, we had zero 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 subsidiaries may sell their accounts receivable up to a maximum of $315.0 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 nine months ended September 30, 2020 and 2019 totaled $614.9 million and $778.9 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 $0.2 million and $0.8 million for the three months ended September 30, 2020 and 2019, respectively, and $1.2 million and $2.3 million for the nine months ended September 30, 2020 and 2019, respectively. The agreements are without recourse and therefore no recourse liability has been recorded as of September 30, 2020, December 31, 2019 and September 30, 2019. As of September 30, 2020, December 31, 2019 and September 30, 2019, $93.1 million, $63.1 million and $107.4 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 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.

For the nine months ended September 30, 2020, cash provided by operating activities decreased by $111.3 million from the nine months ended September 30, 2019, primarily due to a decrease in operating results, partially offset by a decrease in the investment in working capital from the prior year. For the nine months ended September 30, 2020, working capital decreased $179.2 million compared to an increase of $79.9 million for the nine months ended September 30, 2019. Receivables decreased by $57.0 million from December 31, 2019, primarily as a result of lower sales during 2020. Inventories decreased by $90.5 million from December 31, 2019, primarily as a result of lower raw material costs and lower Winchester inventory due to improved commercial ammunition demand. Accounts Payable and Accrued Liabilities increased $52.9 million as a result of specific actions taken by management to improve Olin’s working capital. During 2020, Olin expects to reduce working capital by approximately $150 million, which includes an approximately $75 million investment in working capital to support Lake City operations.

Table of Contents

At September 30, 2020, we had total letters of credit of $79.1 million outstanding, of which $0.4 million were issued under our 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 September 30, 2020, we had long-term borrowings, including the current installment and finance lease obligations, of $3,960.7 million, of which $280.9 million 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 Senior Revolving Credit Facility, Delayed Draw Term Loan Facility, Receivables Financing Agreement and AR Facilities are additional sources of liquidity.

Supplemental Guarantor Financial Information

Off-Balance Sheet Arrangements

Purchasing commitments are utilized in our normal course of business for our projected needs. We have supply contracts with various third parties for certain raw materials including ethylene, electricity, propylene and benzene. These agreements are maintained through long-term cost based contracts that provide us with a reliable supply of key raw materials.

New Accounting Standards

In March 2020, the U.S. Securities and Exchange Commission issued final rule 33-10762, “Financial Disclosures About Guarantors and Issuers of Guaranteed Securities and Affiliates Whose Securities Collateralize a Registrant’s Securities.” In October 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2020-09, “Amendments Pursuant to SEC Release No. 33-10762,” which amends ASC 470, Debt, for this rule. This rule simplifies the disclosure requirements related to registered securities under Rule 3-10 of Regulation S-X by modifying criteria to qualify for an exception to the requirement that an entity file separate financial statements for subsidiary issuers and guarantors. The rule also reduces and, in some cases, eliminates the disclosures an entity must provide in lieu of the subsidiary’s audited financial statements and allows disclosures to be summarized and included within Management’s Discussion and Analysis of Financial Condition and Results of Operations. The rule requires certain enhanced narrative disclosures, including the terms and conditions of the guarantees and how the legal obligations of the issuer and guarantor, as well as other factors, may affect payments to holders of the debt securities. The final rule is effective on January 4, 2021, with earlier application permitted. We adopted the provisions of this rule during the third quarter of 2020 which did not have a material impact on our consolidated financial statements. The adoption of this rule resulted in summarizing our supplemental guarantor financial information in Management’s Discussion and Analysis of Financial Condition and Results of Operations.

In March 2020, the FASB issued ASU 2020-04, “Facilitation 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

Table of Contents

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 and nine months ended September 30, 2020, the adoption of this update did not have a material impact on our consolidated financial statements.

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, see Note 7 “Goodwill and Intangibles” for additional information.

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 September 30, 2020, we maintained open positions on commodity contracts with a notional value totaling $203.5 million ($174.6 million at December 31, 2019 and $167.6 million at September 30, 2019). Assuming a hypothetical 10% increase in commodity prices which are currently hedged, as of September 30, 2020, we would experience a $20.4 million ($17.5 million at December 31, 2019 and $16.8 million at September 30, 2019) 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 $24.6 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 Senior Revolving Credit Facility, Delayed Draw Term Loan, Receivables Financing Agreement and AR Facilities are additional sources of liquidity. As of September 30, 2020, December 31, 2019 and September 30, 2019, we had long-term borrowings, including current installments and finance lease obligations, of $3,960.7 million, $3,340.8 million and $3,340.1 million, respectively, of which $280.9 million, $155.9 million and $155.9 million at September 30, 2020, December 31, 2019 and September 30, 2019, 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 $280.9 million of variable-rate debt levels from September 30, 2020, we estimate that a hypothetical change of 100-basis points in the LIBOR interest rates would impact annual interest expense by $2.8 million.

Our interest rate swaps reduced interest expense by $0.9 million and $1.7 million for the three and nine months ended September 30, 2019, 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 September 30, 2020. 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.

In 2017, we began a multi-year implementation of new enterprise resource planning, manufacturing, and engineering systems. The project includes the required information technology infrastructure (collectively, the Information Technology Project). Implementing the Information Technology Project involves significant changes in business processes and extensive organizational training. During the third quarter of 2020, we implemented portions of the Information Technology Project to support and integrate significant processes, some of which relate to internal control over financial reporting and disclosure controls and procedures. We believe we have taken and will continue to take the necessary steps to implement, monitor and maintain appropriate internal controls during the Information Technology Project transition period. In connection with the Information Technology Project, we expect there will be a significant redesign of our business processes, some of which relate to internal control over financial reporting and disclosure controls. Other than the aforementioned Information Technology Project, there have been no changes in our internal control over financial reporting that occurred during the quarter ended September 30, 2020, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

•	unexpected litigation outcomes;


•	changes in, or failure to comply with, legislation or government regulations or policies;


•	costs and other expenditures in excess of those projected for environmental investigation and remediation or other legal proceedings;


•	failure to attract, retain and motivate key employees;


•	the effects of any declines in global equity markets on asset values and any declines in interest rates used to value the liabilities in our pension plan;


•	adverse changes in international markets, including economic, political or regulatory changes;


•	our long range plan assumptions not being realized causing a non-cash impairment charge of long-lived assets;


•	adverse conditions in the credit and capital markets, limiting or preventing our ability to borrow or raise capital; and


•	various risks associated with our transition and subsequent operation of the Lake City U.S. Army Ammunition Plant.

All of our forward-looking statements should be considered in light of these factors. In addition, other risks and uncertainties not presently known to us or that we consider immaterial could affect the accuracy of our forward-looking statements.

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.

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.
