Notes to Condensed Financial Statements

(Unaudited)

NOTE 1. DESCRIPTION OF BUSINESS

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

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

NOTE 2. RECENT ACCOUNTING PRONOUNCEMENTS

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

NOTE 3. RESTRUCTURING CHARGES

We committed to a productivity initiative to align the organization with our new operating model and improve efficiencies (collectively, Productivity Plan). These actions and related activities were completed during the second quarter of 2021. For the three and nine months ended September 30, 2021, we recorded pretax restructuring charges of $0.2 million and $10.3 million, respectively, for employee severance and related benefit costs related to these actions. We do not expect to incur additional restructuring charges related to these actions.

On May 18, 2021, we announced that we had made the decision to permanently close approximately 20% of our diaphragm-grade chlor alkali capacity, representing 225,000 tons, at our Plaquemine, LA facility (Plaquemine Plan). The closure was completed in the second quarter of 2021. We expect to incur restructuring charges through 2022 of approximately $2 million related to this action.

Table of Contents

On March 15, 2021, we announced that we had made the decision to permanently close approximately 50% of our diaphragm-grade chlor alkali capacity, representing 200,000 tons, at our McIntosh, AL facility (McIntosh Plan). The closure was completed in the first quarter of 2021. For the three and nine months ended September 30, 2021, we recorded pretax restructuring charges of $0.4 million and $5.2 million, respectively, for lease and other contract termination costs related to this action. We expect to incur additional restructuring charges through 2022 of approximately $2 million related to this action.

On January 18, 2021, we announced that we had made the decision to permanently close our trichloroethylene and anhydrous hydrogen chloride liquefaction facilities in Freeport, TX (collectively, Freeport 2021 Plan), before the end of 2021. For the three and nine months ended September 30, 2021, we recorded pretax restructuring charges of $1.6 million and $5.7 million, respectively, for facility exit costs related to these actions. We expect to incur additional restructuring charges through 2023 of approximately $25 million related to these actions.

On December 11, 2019, we announced that we had made the decision to permanently close a chlor alkali plant with a capacity of 230,000 tons and our vinylidene chloride (VDC) production facility, both in Freeport, TX (collectively, Freeport 2019 Plan). The VDC facility and related chlor alkali plant were closed during fourth quarter of 2020 and second quarter of 2021, respectively. For the three months ended September 30, 2021 and 2020, we recorded pretax restructuring charges of $1.0 million and $0.3 million, respectively, for facility exit costs related to these actions. For the nine months ended September 30, 2021 and 2020, we recorded pretax restructuring charges of $2.2 million and $0.8 million, respectively, for facility exit costs related to these actions. We expect to incur additional restructuring charges through 2025 of approximately $45 million related to these actions.

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 (collectively, Chlor Alkali 2016 Plan). Associated with this action, we have permanently closed our Henderson, NV chlor alkali plant with 153,000 tons of capacity and have reconfigured the site to manufacture bleach and distribute caustic soda and hydrochloric acid. Also, the capacity of our Niagara Falls, NY chlor alkali plant has been reduced from 300,000 tons to 240,000 tons and the chlor alkali capacity at our Freeport, TX facility was reduced by 220,000 tons. This 220,000 ton reduction was entirely from diaphragm cell capacity. For the three months ended September 30, 2021 and 2020, we recorded pretax restructuring charges of $0.4 million and $1.0 million, respectively, for facility exit costs and lease and other contract termination costs related to these actions. For the nine months ended September 30, 2021 and 2020, we recorded pretax restructuring charges of $1.1 million and $3.9 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 $1 million related to these capacity reductions.

The following table summarizes the 2021 and 2020 activities by major component of these restructuring actions and the remaining balances of accrued restructuring costs as of September 30, 2021 and 2020:

As of September 30, 2021, we have incurred cash expenditures of $115.6 million and non-cash charges of $137.7 million related to these restructuring actions. The remaining balance of $14.6 million is expected to be paid out through 2031.

Subsequent Event

On October 21, 2021, we announced that we had made a decision to permanently cease operations of the remaining 50% of our diaphragm-grade chlor alkali capacity, representing 200,000 tons, at our McIntosh, AL facility. The closure is expected to be completed by the end of the third quarter of 2022. As a result of this action, we expect to incur approximately $40 million of pretax restructuring costs, none of which is expected to be incurred in 2021. We currently estimate these restructuring costs will primarily consist of facility exit costs to be paid in cash through 2025.

NOTE 4. ACCOUNTS RECEIVABLES

During 2021, we amended our existing $250.0 million Receivables Financing Agreement which expanded the borrowing capacity to $300.0 million (Receivables Financing Agreement) and extended the maturity to September 28, 2024. The Receivables Financing Agreement includes a minimum borrowing requirement of 50% of the facility limit or available borrowing capacity, whichever is less. 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 net leverage ratio covenant that is contained in the $1,615.0 million senior credit facility. As of September 30, 2021, $542.0 million of our trade receivables were pledged as collateral. As of September 30, 2021, we had $150.0 million drawn with $150.0 million of additional borrowing capacity available under the Receivables Financing Agreement. As of both December 31, 2020 and September 30, 2020, we had $125.0 million drawn under the Receivables Financing Agreement.

Olin also has trade accounts receivable factoring arrangements (AR Facilities) and pursuant to the terms of the AR Facilities, certain of our domestic subsidiaries may sell their accounts receivable up to a maximum of $229.0 million and certain of our foreign subsidiaries may sell their accounts receivable up to a maximum of €40.4 million. We will continue to service the outstanding accounts sold. These receivables qualify for sales treatment under ASC 860 “Transfers and Servicing” and, accordingly, the proceeds are included in net cash provided by operating activities in the condensed statements of cash flows. The following table summarizes the AR Facilities activity:


	September 30,
	2021		2020
	($ in millions)
Balance at beginning of year	$	48.8	$	63.1
Gross receivables sold	687.5		614.9
Payments received from customers on sold accounts	(645.6)		(584.9)
Balance at end of period	$	90.7	$	93.1

The factoring discount paid under the AR Facilities is recorded as interest expense on the condensed statements of operations. The factoring discount was $0.3 million and $0.2 million for the three months ended September 30, 2021 and 2020, respectively, and $1.0 million and $1.2 million for the nine months ended September 30, 2021 and 2020, respectively. The agreements are without recourse and therefore no recourse liability had been recorded as of September 30, 2021, December 31, 2020 or September 30, 2020.

Our condensed balance sheets included an allowance for doubtful accounts receivables of $12.2 million, $12.3 million and $12.1 million and other receivables of $68.1 million, $62.4 million and $73.9 million at September 30, 2021, December 31, 2020 and September 30, 2020, respectively, which were included in receivables, net.

NOTE 5. INVENTORIES

Inventories consisted of the following:


	September 30, 2021		December 31, 2020		September 30, 2020
	($ in millions)
Supplies	$	115.5	$	113.8	$	107.6

Work in process	156.3		133.2		96.3
Finished goods	492.2		359.6		363.8
Inventories excluding LIFO reserve	922.5		722.9		654.1
LIFO reserve	(95.7)		(48.2)		(45.7)
Inventories, net	$	826.8	$	674.7	$	608.4

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, 2021 reflect certain estimates relating to inventory quantities and costs at December 31, 2021. The replacement cost of our inventories would have been approximately $95.7 million, $48.2 million and $45.7 million higher than reported at September 30, 2021, December 31, 2020 and September 30, 2020, respectively.

NOTE 6. OTHER ASSETS

Included in other assets were the following:


	September 30, 2021		December 31, 2020		September 30, 2020
	($ in millions)
Supply contracts	$	1,076.8	$	1,122.9	$	1,129.7
Other	75.6		68.4		47.3
Other assets	$	1,152.4	$	1,191.3	$	1,177.0

We have entered into various arrangements for the long-term supply of ethylene and electricity. A payment of $461.0 million was made during the second quarter of 2020 associated with a previously executed option to reserve additional ethylene at producer economics from The Dow Chemical Company (Dow). The original liability was discounted and recorded at present value as of March 31, 2017. For the nine months ended September 30, 2020, $4.0 million of interest expense was recorded for accretion on the 2020 payment liability discount.

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 October 5, 2015 closing date of the acquisition from Dow.

Amortization expense of $17.3 million and $11.3 million for the three months ended September 30, 2021 and 2020, respectively, and amortization expense of $52.1 million and $44.6 million for the nine months ended September 30, 2021 and 2020, respectively, was recognized within cost of goods sold related to our long-term supply contracts and is reflected in depreciation and amortization on the condensed statements of cash flows. The long-term supply contracts are monitored for impairment each reporting period.

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, 2020	$	1,832.7	$	287.0	$	2,119.7
Goodwill impairment	(557.6)		(142.2)		(699.8)
Foreign currency translation adjustment	0.2		—		0.2
Balance at September 30, 2020	$	1,275.3	$	144.8	$	1,420.1
Balance at January 1, 2021	$	1,275.3	$	144.9	$	1,420.2
Foreign currency translation adjustment	0.1		—		0.1
Balance at September 30, 2021	$	1,275.4	$	144.9	$	1,420.3

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. As a further indicator that each reporting unit had been valued appropriately using a discounted cash flow model, the aggregate fair value of all reporting units was 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 reflected 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 was equal their fair value upon completion of the goodwill impairment test.
