OLIN CORPORATION AND CONSOLIDATED SUBSIDIARIES
Notes to Condensed Financial Statements
(Unaudited)

DESCRIPTION OF BUSINESS

Olin Corporation (Olin) is a Virginia corporation, incorporated in 1892, having its principal executive offices in Clayton, MO.  On October 5, 2015 (the Closing Date), we acquired from The Dow Chemical Company (TDCC) its U.S. Chlor Alkali and Vinyl, Global Chlorinated Organics and Global Epoxy businesses (collectively, the Acquired Business), whose operating results are included in the accompanying financial statements since the Closing Date. For segment reporting purposes, a portion of the Acquired Business’s operating results comprise the newly created Epoxy segment with the remaining operating results combined with Olin’s former Chlor Alkali Products and Chemical Distribution segments to comprise the newly created Chlor Alkali Products and Vinyls segment.

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 and downstream products such as converted epoxy resins and additives. The Winchester segment products includeproduces and sells sporting ammunition, law enforcement ammunition, reloading components, small caliber military ammunition and components, and industrial cartridges.

We have prepared the condensed financial statements included herein, without audit, pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (SEC). The preparation of the consolidated 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, 2015 and in Exhibit 99.1 to our Current Report on Form 8-K filed with the SEC on July 29, 2016. Certain reclassifications were made to prior year amounts to conform to the 20162017 presentation.

ACQUISITION
On October 5, 2015 (the Closing Date), we completed the Closing Date, Olin consummated the previously announced mergeracquisition (the Merger), using a Reverse Morris Trust structure,Acquisition) from The Dow Chemical Company (TDCC) of our wholly owned subsidiary, Blue Cube Acquisition Corp.

Pursuant toAcquired Business), whose operating results are included in the Merger Agreement and a Separation Agreement dated March 26, 2015 between TDCC and Spinco (the Separation Agreement), prior to the Merger, (1) TDCC transferred the Acquired Business to Spinco and (2) TDCC distributed Spinco’s stock to TDCC’s shareholders by way of a split-off (the Distribution). Upon consummation of the transactions contemplated by the Merger Agreement and the Separation Agreement (the Transactions), the shares of Spinco common stock then outstanding were automatically converted into the right to receive approximately 87.5 million shares of Olin common stock, which were issued by Olin on the Closing Date, and represented approximately 53% of the outstanding shares of Olin common stock, together with cash in lieu of fractional shares. Olin’s pre-Merger shareholders continued to hold the remaining approximately 47% of the outstanding shares of Olin common stock. On the Closing Date, Spinco became a wholly owned subsidiary of Olin.

The Transactions have been accounted for using the acquisition method of accounting which requires, among other things, that assets acquired and liabilities assumed be recognized at their fair values as of the acquisition date. We finalized our purchase price allocation during the third quarter of 2016. The following table summarizes the final allocation of the purchase price to the Acquired Business’s assets and liabilities on the Closing Date:

Measurement period adjustments to the initial valuation primarily consisted of the final working capital adjustment, the final valuation for the pension liabilities assumed from TDCC, changes in the estimated fair value of acquired intangible assets and property, plant and equipment, and the finalization of deferred tax assets and liabilities. Included in total current assets are cash and cash equivalents of $25.4 million, inventories of $456.4 million and receivables of $401.6 million with a contracted value of $403.8 million. Included in total current liabilities are current installments of long-term debt of $51.1 million.

Based on final valuations, purchase price was allocated to intangible assets as follows:
 October 5, 2015
 Weighted-Average Amortization Period Gross Amount
   ($ in millions)
Customers, customer contracts and relationships15 Years $520.5
Acquired technology7 Years 85.1
Trade name5 Years 7.0
Total acquired intangible assets  $612.6

Based on final valuations as of September 30, 2016, $1,372.5 million was assigned to goodwill, none of which is deductible for tax purposes. The primary reasons for the Acquisition and the principal factors that contributed to the Acquired Business purchase price that resulted in the recognition of goodwill are due to the providing of increased production capacity and diversification of Olin’s product portfolio, cost-saving opportunities and enhanced size and geographic presence. The cost-saving opportunities include improved operating efficiencies and asset optimization.

Goodwill recorded in the Acquisition is not amortized but will be reviewed for impairment annually in the fourth quarter and/or when circumstances or other events indicate that impairment may have occurred.



Transaction financing

Prior to the Distribution, TDCC received from Spinco distributions of cash and debt instruments of Spinco with an aggregate value of $2,095.0 million (collectively, the Cash and Debt Distribution). On the Closing Date, Spinco issued $720.0 million aggregate principal amount of 9.75% senior notes due October 15, 2023 (2023 Notes) and $500.0 million aggregate principal amount of 10.0% senior notes due October 15, 2025 (2025 Notes and, together with the 2023 Notes, the Notes) to TDCC. TDCC transferred the Notes to certain unaffiliated securityholders in satisfaction of existing debt obligations of TDCC held or acquired by those unaffiliated securityholders. On October 5, 2015, certain initial purchasers purchased the Notes from the unaffiliated securityholders. During 2016, the Notes were registered under the Securities Act of 1933, as amended. Interest on the Notes began accruing from October 1, 2015 and are paid semi-annually beginning on April 15, 2016. The Notes are not redeemable at any time prior to October 15, 2020. Neither Olin nor Spinco received any proceeds from the sale of the Notes. Upon the consummation of the Transactions, Olin became guarantor of the Notes.

On June 23, 2015, Spinco entered into a new five-year delayed-draw term loan facility of up to $1,050.0 million. As of the Closing Date, Spinco drew $875.0 million to finance the cash portion of the Cash and Debt Distribution. Also on June 23, 2015, Olin and Spinco entered into a new five-year $1,850.0 million senior credit facility consisting of a $500.0 million senior revolving credit facility, which replaced Olin’s $265.0 million senior revolving credit facility at the closing of the Merger, and a$1,350.0 million (subject to reduction by the aggregate amount of the term loans funded to Spinco under the Spinco term loan facility) delayed-draw term loan facility. As of the Closing Date, an additional $475.0 million was drawn by Olin under this term loan facility which was used to pay fees and expenses of the Transactions, obtain additional funds for general corporate purposes and refinance Olin’s existing senior term loan facility due in 2019. Subsequent to the Closing Date, these senior credit facilities were consolidated into a single $1,850.0 million senior credit facility, which includes a $1,350.0 million term loan facility. This new senior credit facility will expire in 2020. The $500.0 million senior revolving credit facility includes a $100.0 million letter of credit subfacility. The term loan facility includes amortization payable in equal quarterly installments at a rate of 5.0% per annum for the first two years, increasing to 7.5% per annum for the following year and to 10.0% per annum for the last two years. Under the new senior credit facility, we may select various floating rate borrowing options. The actual interest rate paid on borrowings under the senior credit facility is based on a pricing grid which is dependent upon the leverage ratio as calculated under the terms of the facility for the prior fiscal quarter. The facility includes various customary restrictive covenants, including restrictions related to the ratio of debt to earnings before interest expense, taxes, depreciation and amortization (leverage ratio) and the ratio of earnings before interest expense, taxes, depreciation and amortization to interest expense (coverage ratio). Compliance with these covenants is determined quarterly based on the operating cash flows.

On August 25, 2015, Olin entered into a Credit Agreement (the Credit Agreement) with a syndicate of lenders and Sumitomo Mitsui Banking Corporation (Sumitomo), as administrative agent, in connection with the Transactions. The Credit Agreement provides for a term credit facility (the Sumitomo Credit Facility) under which Olin obtained term loans in an aggregate amount of $600.0 million. On November 3, 2015, we entered into an amendment to the Sumitomo Credit Facility which increased the aggregate amount of term loans available by $200.0 million. On the Closing Date, $600.0 million of loans under the Credit Agreement were made available and borrowed upon and on November 5, 2015, $200.0 million of loans under the Credit Agreement were made available and borrowed upon. The term loans under the Sumitomo Credit Facility will mature on October 5, 2018 and will have no scheduled amortization payments. The proceeds of the Sumitomo Credit Facility were used to refinance existing Spinco indebtedness outstanding at the Closing Date, to pay fees and expenses in connection with the Transactions and for general corporate purposes. The Credit Agreement contains customary representations, warranties and affirmative and negative covenants which are substantially similar to those included in the new $1,850.0 million senior credit facility.

On March 26, 2015, we and certain financial institutions executed commitment letters pursuant to which the financial institutions agreed to provide $3,354.5 million of financing to Spinco to finance the amount of the Cash and Debt Distribution and to provide financing, if needed, to Olin to refinance certain of our existing debt (the Bridge Financing), in each case on the terms and conditions set forth in the commitment letters. The Bridge Financing was not drawn on to facilitate the Transactions, and the commitments for the Bridge Financing were terminated as of the Closing Date. For the nine months ended September 30, 2015, we paid deferred debt issuance costs of $18.7 million associated with the Bridge Financing.

Other acquisition-related transactions

In connection with the Transactions, certain additional agreements have been entered into, including, among others, an Employee Matters Agreement, a Tax Matters Agreement, site, transitional and other services agreements, supply and purchase agreements, real estate agreements, technology licenses and intellectual property agreements. For the nine months ended September 30, 2016, payments of $69.5 million were made related to certain acquisition-related liabilities, including the final working capital adjustment.



In addition, Olin and TDCC have agreed to enter into arrangements for the long-term supply of ethylene by TDCC to Olin, pursuant to which, among other things, Olin has made upfront payments of $433.5 million upon the closing of the Merger in order to receive ethylene at producer economics and for certain reservation fees for the option to obtain additional future ethylene supply at producer economics. The fair value of the long-term supply contracts recorded as of the Closing Date was a long-term asset of $416.1 million which will be amortized over the life of the contracts as ethylene is received. During the three months ended June 30, 2016, one of the options to obtain additional future ethylene supply at producer economics was exercised by us and, accordingly, additional payments will be made to TDCC of approximately $210 million in 2017, which will increase the value of the long-term asset. If the remaining option is exercised by us, additional payments will be made to TDCC of between $425 million and $465 million in 2020, which will increase the value of the long-term asset.

In connection with the Transactions and effective October 1, 2015, we filed a Certificate of Amendment to our Articles of Incorporation to increase the number of authorized shares of Olin common stock from 120.0 million shares to 240.0 million shares.

The pro forma financial information was prepared based on historical financial information and has been adjusted to give effect to pro forma adjustments that are (i) directly attributable to the Transactions, (ii) factually supportable and (iii) expected to have a continuing impact on the combined results. The pro forma statement of income uses estimates and assumptions based on information available at the time. Management believes the estimates and assumptions to be reasonable; however, actual results may differ significantly from this pro forma financial information. The pro forma results presented do not include any anticipated synergies or other expected benefits that may be realized from the Transactions. The pro forma information is not intended to reflect the actual results that would have occurred had the companies actually been combined during the period presented.

The pro forma results for the three and nine months ended September 30, 2015 primarily include recurring adjustments for re-pricing of sales, raw materials and services to/from TDCC relating to arrangements for long-term supply agreements for the sale of raw materials, including ethylene and benzene, and services pursuant to the Separation Agreement, adjustments to eliminate historical sales between the Acquired Business and Olin, additional amortization expense related to the fair value of acquired identifiable intangible assets, additional depreciation expense related to the fair value adjustment to property, plant and equipment, interest expense related to the incremental debt issued in conjunction with the Acquisition and an adjustment to tax-effect the aforementioned pro forma adjustments using an estimated aggregate statutory income tax rate of the jurisdictions to which the above adjustments relate.

In addition to the above recurring adjustments, the pro forma results for the three and nine months ended September 30, 2015 included non-recurring adjustments of $4.7 million and $21.1 million, respectively, relating to the elimination of transaction costs incurred that are directly related to the Transactions, and do not have a continuing impact on our combined operating results.



RESTRUCTURING CHARGES

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 will reconfigurehave 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 SeptemberJune 30, 2017 and 2016, we recorded pretax restructuring charges of $4.9$7.4 million and $7.9 million, respectively, for employee severance and related benefit costs, employee relocation costs, and facility exit costs and lease and other contract termination costs related to these actions. For the ninesix months ended SeptemberJune 30, 2017 and 2016, we recorded pretax restructuring charges of $105.0$14.9 million and $100.1 million, respectively, for the write-off of equipment and facility costs, lease and other contract termination costs, employee severance and related benefit costs, employee relocation costs and facility exit costs related to these actions. We expect to incur additional restructuring charges through 2020 of approximately $45$25 million related to these capacity reductions. This estimate of additional restructuring charges does not include any additional charges related to a contract termination that is currently in dispute. The other party to the contract has filed a demand for arbitration alleging, among other things, that Olin breached the related agreement and claimed damages in excess of the amount Olin believes it is obligated for under the contract. 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 effect on our financial results.

On December 12, 2014, we announced that we had made the decision to permanently close the portion of the Becancour, Canada chlor alkali facility that has been shut down since late June 2014. This action reduced the facility’s chlor alkali capacity by 185,000 tons. Subsequent to the shut down, the plant predominantly focuses on bleach and hydrochloric acid, which are value-added products, as well as caustic soda. For the three months ended SeptemberJune 30, 20162017 and 2015,2016, we recorded pretax restructuring charges of less than $0.1$1.1 million and $0.1 million, respectively, for facility exit costs related to these actions. For the ninesix months ended SeptemberJune 30, 20162017 and 2015,2016, we recorded pretax restructuring charges of $0.4$1.8 million and $1.7$0.4 million, respectively, for lease and other contract termination costs and facility exit costs and employee severance and related benefit costs related to these actions. We expect to incur additional restructuring charges through 20172018 of approximately $4$5 million related to the shut down of this portion of the facility.

On November 3, 2010, we announced that we made the decision to relocate the Winchester centerfire pistol and rifle ammunition manufacturing operations from East Alton, IL to Oxford, MS. This relocation, when completed, is forecast to reduce Winchester’s annual operating costs by approximately $35 million to $40 million. Consistent with this decision in 2010, we initiated an estimated $110 million five-year project, which includesincluded approximately $80 million of capital spending. The capital spending was partially financed by $31 million of grants provided by the State of Mississippi and local governments. We completed thisDuring 2016, the final rifle ammunition production equipment relocation in the second quarter of 2016.was completed. For the three and six months ended SeptemberJune 30, 2016, and 2015, we recorded pretax restructuring charges of $0.3$0.2 million and $0.2$0.5 million, respectively, for employee relocation costs and facility exit costs related to these actions. For the nine months ended September 30, 2016 and 2015, we recorded pretax restructuring charges of $0.8 million and $0.5 million, respectively, for employee severance and related benefit costs, employee relocation costs and facility exit costs related to these actions. We expect to incur additional restructuring charges through 2016 of less than $1 million related to the transfer of these operations.

ACCOUNTS RECEIVABLES

On December 20, 2016, we entered into a three year, $250.0 million Receivables Financing Agreement with PNC Bank, National Association, as administrative agent (Receivables Financing Agreement). Under the Receivables Financing Agreement, our eligible trade receivables are used for collateralized borrowings and continue to be serviced by us. As of June 30, 2017, $326.1 million of our trade receivables were pledged as collateral and we had $210.0 million drawn under the agreement. As of June 30, 2017, we had additional borrowing capacity of $32.3 million under the Receivables Financing Agreement. As of December 31, 2016, $282.3 million of our trade receivables were pledged as collateral and $210.0 million was drawn under the agreement. For the year ended December 31, 2016, the proceeds of the Receivables Financing Agreement were used to repay $210.0 million of the $800.0 million Sumitomo term loan facility (the Sumitomo Credit Facility). In addition, the Receivables Financing Agreement incorporates the leverage and coverage covenants that are contained in the senior revolving credit facilities.

On June 29, 2016, we entered into a trade accounts receivable factoring arrangement which was amended on September 1, 2016 and, on December 22, 2016, we entered into a separate trade accounts receivable factoring arrangement which was amended on March 24, 2017 (collectively the AR Facilities). Pursuant to the terms of the AR Facilities, certain of our subsidiaries may sell their accounts receivable up to a maximum of $256.5 million. We will continue to service such accounts.  These receivables qualify for sales treatment under Accounting Standards Codification (ASC) 860 “Transfers and Servicing” (ASC 860) and, accordingly, the proceeds are included in net cash provided by operating activities in the condensed statements of cash flows.  The gross amount of receivables sold for the three months ended June 30, 2017 and 2016 totaled $388.0 million and $26.8 million, respectively, and for the six months ended June 30, 2017 and 2016 totaled $777.6 million and $26.8 million, respectively.  The factoring discount paid under the AR Facilities is recorded as interest expense on the condensed statements of operations. The agreements are without recourse and therefore no recourse liability has been recorded as of June 30, 2017.  As of June 30, 2017, December 31, 2016 and June 30, 2016, $148.4 million, $126.1 million and $26.8 million, respectively, of receivables qualifying for sales treatment were outstanding and will continue to be serviced by us.


ALLOWANCE FOR DOUBTFUL ACCOUNTS RECEIVABLES

We evaluate the collectibility of accounts receivable based on a combination of factors. We estimate an allowance for doubtful accounts as a percentage of net sales based on historical bad debt experience. 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 receivable consisted of the following:

Provisions charged (credited) to operations were $1.4$0.7 million and $(0.2)$0.8 million for the three months ended SeptemberJune 30, 2017 and 2016, and 2015, respectively.

On June 29, 2016, we entered into a trade accounts receivable factoring arrangement (the AR Facility) which was amended on September 1, 2016. Pursuant to the terms of the AR Facility, certain of our subsidiaries may sell their accounts receivable up to a maximum of $185.0 million. We will continue to service such accounts.  These receivables qualify for sales treatment under Accounting Standards Codification (ASC) 860 “Transfers and Servicing” (ASC 860) and, accordingly, the proceeds are included in net cash provided by operating activities in the condensed statements of cash flows.  The gross amount of receivables sold for the three and nine months ended September 30, 2016 totaled $209.9 million and $236.7 million, respectively.  The factoring discount paid under the AR Facility is recorded as interest expense on the condensed statements of operations. The agreement is without recourse and therefore no recourse liability has been recorded as of September 30, 2016.  As of September 30, 2016, $85.0 million of receivables qualifying for sale treatment were outstanding and will continue to be serviced by us.

In conjunction with the Acquisition, we obtained inventories with a fair value of $456.4 million as of October 5, 2015. Inventories are valued at the lower of cost or market.and net realizable value. For U.S. inventories, inventory costs are determined principally by the dollar value 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 SeptemberJune 30, 20162017 reflect certain estimates relating to inventory quantities and costs at December 31, 2016.2017. The replacement cost of our inventories would have been approximately $40.8$47.9 million, $43.9$35.9 million and $63.5$33.0 million higher than reported at SeptemberJune 30, 2016,2017, December 31, 20152016 and SeptemberJune 30, 2015,2016, respectively.

In connection with the Acquisition, Olin and TDCC have agreed to enterentered into arrangements for the long-term supply of ethylene by TDCC to Olin, pursuant to which, among other things, Olin has made upfront payments of $433.5 million uponon the Closing Date in order to receive ethylene at producer economics and for certain reservation fees for the option to obtain additional future ethylene supply at producer economics. The fair value of the long-term supply contracts recorded as of the Closing Date was a long-term asset of $416.1 million which will be amortized over the life of the contracts as ethylene is received. During the three months ended June 30, 2016, one of the options to obtainreserve additional future ethylene supply at producer economics was exercised by us and, accordingly, additional payments will be made to TDCC of approximately $210$209.4 million in 2017, which will increase the value of the long-term asset. IfOn February 27, 2017, we exercised the remaining option is exercised by us,to reserve additional future ethylene supply and, in connection with the exercise, we also secured a long-term customer arrangement. Consequently, additional payments will be made to TDCC of between $425 million and $465 million inon or about the fourth quarter of 2020, which will increase the value of the long-term asset.

During 2016, Olin entered into arrangements to increase itsour supply of low cost electricity.  In conjunction with these arrangements, Olin made payments of $175.7 million duringin 2016, including $85.0 million for the ninesix months ended SeptemberJune 30, 2016.  The payments made under these arrangements will be amortized over the life of the contracts as electrical power is received.

Amortization expense of $6.0$6.3 million and $14.7$4.4 million for the three months ended June 30, 2017 and 2016, respectively, and $12.6 million and $8.7 million for the six months ended June 30, 2017 and 2016, respectively, was recognized within cost of goods sold for the three and nine months ended September 30, 2016, respectively, related to these 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.

Intangible assets with indefinite useful lives are reviewed annually in the fourth quarter and/or when circumstances or other events indicate the indefinite life is no longer supportable. In connection with the integration of the Acquired Business, in the first quarter of 2016, the KAK.A. Steel Chemicals Inc. trade name was changed from an indefinite life intangible asset to an intangible asset with a finite useful life of one year. Amortization expense of $2.7$2.8 million and $8.2$5.5 million was recognized within cost of goods sold for the three and ninesix months ended SeptemberJune 30, 2016, respectively, related to the change in useful life.



EARNINGS PER SHARE

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

ENVIRONMENTAL

We are party to various government and private environmental actions associated with past manufacturing facilities and former waste disposal sites. Charges to income for investigatory and remedial efforts were material to operating results in 2015 and are expected to be material in 2016. The condensed balance sheets included reserves for future environmental expenditures to investigate and remediate known sites amounting to $137.5$135.7 million, $138.1137.3 million and $139.9138.9 million at SeptemberJune 30, 20162017, December 31, 20152016 and SeptemberJune 30, 20152016, respectively, of which $118.5$118.7 million, $119.1120.3 million and $120.9119.9 million, respectively, were classified as other noncurrent liabilities.


Environmental provisions charged to income, which are included in cost of goods sold, were $0.4$1.8 million and $7.3$2.4 million for the three months ended SeptemberJune 30, 20162017 and 2015,2016, respectively, and $5.5$4.4 million and $13.1$5.1 million for the ninesix months ended SeptemberJune 30, 20162017 and 2015,2016, respectively.

In connection with the Acquisition, TDCC retained liabilities relating to releases of hazardous materials and violations of environmental law to the extent arising prior to the Closing Date.

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.



COMMITMENTS AND CONTINGENCIES

We, and our subsidiaries, are defendants in various legal actions (including proceedings based on alleged exposures to asbestos) incidental to our past and current business activities. As of SeptemberJune 30, 2016,2017, December 31, 20152016 and SeptemberJune 30, 2015,2016, our condensed balance sheets included liabilities for these legal actions of $22.9$15.9 million, $21.2$13.6 million and $22.7$22.1 million, respectively. These liabilities do not include costs associated with legal representation. Based on our analysis, and considering the inherent uncertainties associated with litigation, we do not believe that it is reasonably possible that these legal actions will materially adversely affect our financial position, cash flows or results of operations. In connection with the Acquisition, TDCC retained liabilities related to litigation to the extent arising prior to the Closing Date. In addition to the aforementioned legal actions, we are party to a dispute relating to a contract termination. The other party to the contract has filed a demand for arbitration alleging, among other things, that Olin breached the related agreement and claimed damages in excess of the amount Olin believes it is obligated for under the contract. 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 effect on our financial results.

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” (ASC 450) and, therefore, do not record gain contingencies and recognize income until it is earned and realizable.

For the ninesix months ended SeptemberJune 30, 2016, we recognized an insurance recovery of $11.0 million in other operating income (expense) income for property damage and business interruption related to a 2008 chlor alkali facility incident.

For the nine months ended September 30, 2015, we recognized insurance recoveries of $52.2 million for property damage and business interruption related to the portion of the Becancour, Canada chlor alkali facility that has been shut down since late June 2014. Cost of goods sold was reduced by $9.0 million and selling and administration was reduced by $0.9 million for the reimbursement of costs incurred and expensed in prior periods and other operating (expense) income included a gain of $42.3 million. The condensed statement of cash flows for the nine months ended September 30, 2015 included $24.0 million for the property damage portion of the insurance recoveries within proceeds from disposition of property, plant and equipment and gains on disposition of property, plant and equipment.

SHAREHOLDERS’ EQUITY

On April 24, 2014, our board of directors authorized a share repurchase program for up to 8 million shares of common stock that will terminate in three years for any of the remaining shares not yet repurchased.terminated on April 24, 2017. For the ninesix months ended SeptemberJune 30, 20162017 and 2015,2016, no shares were purchased and retired. As of September 30, 2016, we hadWe purchased a total of 1.9 million shares under the April 2014 program, and the 6.1 million shares that remained authorized to be purchased. Under the Merger Agreement relatingpurchased have expired. Related to the Acquisition, we were restricted from repurchasing shares of our common stock prior to the consummation of the Merger. Forfor a period of two years subsequent to the Closing Date, of the Merger, we will continue to beare subject to certain restrictions on our ability to conduct share repurchases.

We issued less than 0.10.9 million shares and less than 0.1 million shares representing stock options exercised for the ninesix months ended SeptemberJune 30, 20162017 and 2015,2016, respectively, with a total value of $0.4$15.8 million and $3.1$0.2 million, respectively.

SEGMENT INFORMATION

We define segment results as income (loss) before interest expense, interest income, other operating income (expense), and income taxes, and include the operating results of non-consolidated affiliates. Consistent with the guidance in ASC 280 “Segment Reporting” (ASC 280), we have determined it is appropriate to include the operating results of non-consolidated affiliates in the relevant segment financial results. Beginning in the fourth quarter of 2015, we modified our reportable segments due to changes in our organization resulting from the Acquisition. We have three operating segments: Chlor Alkali Products and Vinyls, Epoxy and Winchester. For segment reporting purposes, the Acquired Business’s Global Epoxy operating results comprise the newly created Epoxy segment and the Acquired Chlor Alkali Business operating results combined with our former Chlor Alkali Products and Chemical Distribution segments comprise the newly created Chlor Alkali Products and Vinyls segment. The new reporting structure has been retrospectively applied to the financial results for all periods presented. The three operating segments reflect the organization used by our management for purposes of allocating resources and assessing performance. Chlorine used in our Epoxy segment is transferred at cost from the Chlor Alkali Products and Vinyls segment. Sales and profits are recognized in the Chlor Alkali Products and Vinyls segment for all caustic soda generated and sold by Olin.

Dividend yield for 20162017 and 20152016 was based on a historical average. 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.

PENSION PLANS AND RETIREMENT BENEFITSDEBT

MostOn March 9, 2017, we entered into a new five-year $1,975.0 million senior credit facility, which amended and restated the existing $1,850.0 million senior credit facility (the Senior Credit Facility). Pursuant to the agreement, the aggregate principal amount under the term loan facility was increased to $1,375.0 million (Term Loan Facility), and the aggregate commitments under the senior revolving credit facility were increased to $600.0 million (Senior Revolving Credit Facility and, together with the Term Loan Facility, the Amended Senior Credit Facility), from $500.0 million. In March 2017, we drew the entire $1,375.0 million term loan and used the proceeds to redeem the remaining balance of the existing Senior Credit Facility and a portion of the Sumitomo Credit Facility. The maturity date for the Amended Senior Credit Facility was extended from October 5, 2020 to March 9, 2022. The $600.0 million Senior Revolving Credit Facility includes a $100.0 million letter of credit subfacility. The Term Loan Facility includes amortization payable in equal quarterly installments at a rate of 5.0% per annum for the first two years, increasing to 7.5% per annum for the following year and to 10.0% per annum for the last two years.

Under the Amended Senior Credit Facility, we may select various floating rate borrowing options. The actual interest rate paid on borrowings under the Amended Senior Credit Facility is based on a pricing grid which is dependent upon the leverage ratio as calculated under the terms of the applicable facility for the prior fiscal quarter.  The facility includes various customary restrictive covenants, including restrictions related to the ratio of debt to earnings before interest expense, taxes, depreciation and amortization (leverage ratio) and the ratio of earnings before interest expense, taxes, depreciation and amortization to interest expense (coverage ratio).  Compliance with these covenants is determined quarterly based on the operating cash flows. We were in compliance with all covenants and restrictions under all our outstanding credit agreements as of June 30, 2017, 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 of June 30, 2017, as a result of our employees participate inrestrictive covenant related to the leverage ratio, the maximum additional borrowings available to us were $547.1 million.  This limitation would restrict our ability to borrow the maximum amounts available under the Senior Revolving Credit Facility and the Receivables Financing

Agreement.  As of June 30, 2017, there were no other covenants or other restrictions that would have limited our ability to borrow.

On March 9, 2017, Olin issued $500.0 million aggregate principal amount of 5.125% senior notes due September 15, 2027 (2027 Notes), which were registered under the Securities Act of 1933, as amended. Interest on the 2027 Notes began accruing from March 9, 2017 and is paid semi-annually beginning on September 15, 2017. Proceeds from the 2027 Notes were used to redeem the remaining balance of the Sumitomo Credit Facility.

For the six months ended June 30, 2017, we recognized interest expense of $2.7 million for the write-off of unamortized deferred debt issuance costs related to these actions. For the six months ended June 30, 2017, we paid debt issuance costs of $11.2 million relating to the Amended Senior Credit Facility and the 2027 Notes.

CONTRIBUTING EMPLOYEE OWNERSHIP PLAN

The Contributing Employee Ownership Plan (CEOP) is a defined contribution pension plans.plan available to essentially all domestic employees.  We provide a contribution to an individual retirement contribution account maintained with the Contributing Employee Ownership Plan (CEOP) primarilyCEOP equal to an amount of between 5% and 10% of the employee’s eligible compensation.  The defined contribution pension plansplan expense was $6.0 million and $4.0 million for the three months ended SeptemberJune 30, 2017 and 2016 was $6.0 million and 2015,$6.7 million, respectively, and $20.8for the six months ended June 30, 2017 and 2016 was $12.6 million and $12.9$13.3 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 ninethree months ended SeptemberJune 30, 2017 and 2016 were $2.5 million and 2015,$2.9 million, respectively, and for the six months ended June 30, 2017 and 2016 were $5.2 million and $5.6 million, respectively. The increase

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 pension plans expense was due to the additional employees added in conjunction with the Acquired Business.

Aplans.  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 statutory practices.

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



We also provide certain postretirement health carehealthcare (medical) and life insurance benefits for eligible active and retired domestic employees. The health carehealthcare plans are contributory with participants’ contributions adjusted annually based on medical rates of inflation and plan experience.
Effective as of the Closing Date, we changed the approach used to measure service and interest costs for our defined benefit pension plans and on December 31, 2015 changed this approach for our other postretirement benefits. Prior to the change, we measured service and interest costs utilizing a single weighted-average discount rate derived from the yield curve used to measure the plan obligations. Subsequent to the change, we elected to measure service and interest costs by applying the specific spot rates along the yield curve to the plans’ estimated cash flows. We believe the new approach provides a more precise measurement of service and interest costs by aligning the timing of the plans’ liability cash flows to the corresponding spot rates on the yield curve. This change does not affect the measurement of our plan obligations. We have accounted for this change as a change in accounting estimate and, accordingly, have accounted for it on a prospective basis.
As of the Closing Date and as part of the Acquisition, our U.S. qualified defined benefit pension plan assumed certain U.S. qualified defined benefit pension obligations and assets related to active employees and certain terminated, vested retirees of the Acquired Business with a net liability of $281.7 million. In connection therewith, pension assets were transferred from TDCC’s U.S. qualified defined benefit pension plans to our U.S. qualified defined benefit pension plan. Immediately prior to the Acquisition, the Acquired Business’s participant accounts assumed in the Acquisition were closed to new participants and were no longer accruing additional benefits.
Also as of the Closing Date, we assumed certain accrued defined benefit pension liabilities relating to employees of TDCC in Germany, Switzerland and other international locations who transferred to Olin in connection with the Acquisition. The net liability assumed as of the Closing Date was $160.6 million.

Under ASC 740 “Income Taxes” (ASC 740), companies are required to apply their estimated annual tax rate on a year-to-date basis in each interim period. Under ASC 740, companies should not apply the estimated annual tax rate to interim financial results if the estimated annual tax rate is not reliably predictable. In this situation, the interim tax rate should be based on the actual year-to-date results. Based on our year-to-date pretaxthe losses for the six months ended June 30, 2016 and the full year pretax projections as of SeptemberJune 30, 2016, as well as the existence of large favorable permanent book-tax differences for 2016, a reliable projection of our annual effective tax rate has beenas of June 30, 2016 was difficult to determine, producing significant variations in the customary relationship between income tax expense and pretax book income in interim periods, as a small change in forecasted pretax income could cause a significant change in the estimated annual effective tax rate. Consequently, the effective tax rates for the three and ninesix months ended SeptemberJune 30, 2016 arewere determined based on year-to-date results rather than utilizing the method of calculating an estimated annual effective tax rate which was used up until the period ended March 31, 2016.2016 and for the three and six months ended June 30, 2017. The year-to-date actual discrete method will bewas applied for the remainder of 2016.

The effective tax raterates for both the three and six months ended June 30, 2017 included a benefit of $9.5 million related to an agreement reached with the Internal Revenue Service (IRS) for the three months ended September 30, 2015 included the cumulative effectyears 2008, 2010 to 2012 tax examinations and a benefit of changes to our annual estimated effective tax rate from prior quarters.

$0.9 million and $2.4 million, respectively, associated with stock-based compensation. The effective tax rate for the ninesix months ended SeptemberJune 30, 2017 also included $1.0 million of tax expense associated with prior year tax positions.

The effective tax rates for both the the three and six months ended June 30, 2016 included a benefit of $5.2$4.5 million associated with a return to provision adjustment for the finalization of our prior years’ U.S. federal and state income tax returns. The June 30, 2016 return to provision adjustment for the nine months ended September 30, 2016 included $14.9$14.2 million of benefit primarily associated with a change in estimate related to the calculation of salt depletion and $9.7 million of expense associated with the correction of an immaterial error related to non-deductible acquisition costs. The effective tax raterates for the ninethree and six months ended SeptemberJune 30, 2016 also included an expense of $4.1$4.9 million and $4.0 million, respectively, related to changes in uncertain tax positions for prior tax years. The effective tax rates for the three and nine months ended September 30, 2015 included a benefit of less than $0.1 million and $1.1 million, respectively, associated with a return to provision adjustment for the finalization of our prior years’ U.S. federal and state income tax returns. The effective tax rate for the nine months ended September 30, 2015 also included an expense of $0.3 million related to the remeasurement of deferred taxes due to an increase in state effective tax rates.



The condensed balance sheets include income tax receivables that are classified as other noncurrent assets of zero, $1.5 million and $1.5 million at September 30, 2016, December 31, 2015 and September 30, 2015, respectively.

As of SeptemberJune 30, 2016,2017, we had $38.0$34.3 million of gross unrecognized tax benefits, which would have a net $36.3$32.8 million impact on the effective tax rate, if recognized. As of SeptemberJune 30, 2015,2016, we had $35.0$37.5 million of gross unrecognized tax benefits, of which $33.5$35.8 million would have impacted the effective tax rate, if recognized.

In May 2017, we reached an agreement in principle with the IRS regarding their examination of our U.S. income tax returns for 2008, 2010 to 2012. The settlement resulted in a reduction of income tax expense of $9.5 million related primarily to favorable adjustments in uncertain tax positions for prior tax years.

As of SeptemberJune 30, 2016,2017, we believe it is reasonably possible that our total amount of unrecognized tax benefits will decrease by approximately $10.7$1.4 million over the next twelve months. The anticipated reduction primarily relates to settlements with taxing authorities and the expiration of federal, state and foreign statutes of limitation.

We operate globally and file income tax returns in numerous jurisdictions. Our tax returns are subject to examination by various federal, state and local tax authorities. OurNone of our U.S. federal income tax returns are currently under examination by the Internal Revenue Service (IRS) for tax years 2008 and 2010 to 2012.IRS. In connection with the Acquisition, TDCC retained liabilities relating to taxes to the extent arising prior to the Closing Date. 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:

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 statement of financial position and measure those instruments at fair value. We use hedge accounting treatment for substantially all of our business transactions whose risks are covered using derivative instruments. In accordance with ASC 815, we designate derivative contracts as cash flow hedges of forecasted purchases of commodities and forecasted interest payments related to variable-rate borrowings and designate certain interest rate swaps as fair value hedges of fixed-rate borrowings. We do not enter into any derivative instruments for trading or speculative purposes.



Energy costs, including electricity and natural gas, and certain raw materials used in our production processes are subject to price volatility. Depending on market conditions, we may enter into futures contracts, forward contracts, commodity swaps and put and call option contracts in order to reduce the impact of commodity price fluctuations. The majority of our commodity derivatives expire within one year. Those commodity contracts that extend beyond one year correspond with raw material purchases for long-term fixed-price sales contracts.

Olin actively manages 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 resulting from purchaseto offset our net exposures, by currency, related to the foreign currency denominated monetary assets and sale commitments denominated in foreign currencies.liabilities of our operations. At SeptemberJune 30, 2016,2017, we had outstanding forward contracts to buy foreign currency with a notional value of $89.5$71.8 million and to sell foreign currency with a notional value of $110.7$90.4 million. All of the currency derivatives expire within one year and are for U.S. dollar (USD) equivalents. The counterparties to the forward contracts wereare 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, 2015,2016, we had outstanding forward contracts to buy foreign currency with a notional value of $21.7$73.2 million and to sell foreign currency with a notional value of $10.1$100.8 million. At SeptemberJune 30, 2015,2016, we had nooutstanding forward contracts to buy orforeign currency with a notional value of $86.5 million and to sell foreign currencies.

In March 2010, we entered into interest rate swaps on $125 million of our underlying fixed-rate debt obligations, whereby we agreed to pay variable rates tocurrency with a counterparty who, in turn, paid us fixed rates. The counterparty to these agreements was Citibank, N.A. (Citibank), a major financial institution. In October 2011, we entered into $125 million of interest rate swaps with equal and opposite terms as the $125 million variable interest rate swaps on the 6.75% senior notes due 2016 (2016 Notes). We have agreed to pay a fixed rate to a counterparty who, in turn, paid us variable rates. The counterparty to these agreements was also Citibank. The result was a gain of $11.0 million on the $125 million variable interest rate swaps, which as of September 30, 2016 has been recognized. In October 2011, we de-designated our $125 million interest rate swaps that had previously been designated as fair value hedges. The $125 million variable interest rate swaps and the $125 million fixed interest rate swaps did not meet the criteria for hedge accounting. All changes in the fairnotional value of these interest rate swaps were recorded currently in earnings.$117.7 million.

Cash flow hedges

ASC 815 requires that all derivative instruments be recorded on the balance sheet at their fair value. 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. Gains and losses on the derivatives representing hedge ineffectiveness are recognized currently in earnings.

We had the following notional amount of outstanding commodity contracts that were entered into to hedge forecasted purchases:

As of SeptemberJune 30, 2016,2017, the counterparties to these commodity contracts were Wells Fargo Bank, N.A. (Wells Fargo) ($43.829.3 million), Citibank ($22.229.8 million), Merrill Lynch Commodities, IncInc. ($18.727.4 million) and JPMorgan Chase Bank, National Association ($16.69.2 million), all of which are major financial institutions.

We use cash flow hedges for certain raw material and energy costs such as copper, zinc, lead, 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 the company’s manufacturing process. At SeptemberJune 30, 2016,2017, we had open positions in futures contracts through 2021.2022. If all open futures contracts had been settled on SeptemberJune 30, 2016,2017, we would have recognized a pretax lossgain of $2.9$1.9 million.

If commodity prices were to remain at SeptemberJune 30, 20162017 levels, approximately $1.7$0.1 million of deferred losses 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.



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 is for twelve months beginning on December 31, 2016, December 31, 2017 and December 31, 2018, respectively. The counterparties to the agreements are SMBC Capital Markets, Inc., Wells Fargo, PNC Bank, National Association and Toronto-Dominion Bank. These counterparties 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. We have designated the swaps as cash flow hedges of the risk of changes in interest payments associated with our variable-rate borrowings. Accordingly, the swap agreements have been recorded at their fair market value of $9.6 million and are included in other current assets and other assets on the accompanying condensed balance sheet as of June 30, 2017, with the corresponding gain deferred as a component of other comprehensive loss. For both the three and six months ended June 30, 2017, $0.5 million of income was recorded to interest expense on the accompanying condensed statement of operations related to these swap agreements. No gain or loss has been recorded in earnings as a result of ineffectiveness.

We use interest rate swaps as a means of minimizing significant unanticipated earningscash flow fluctuations that may arise from volatility in interest rates of our variable-rate borrowings. These interest rate swaps are treated as cash flow hedges. At SeptemberJune 30, 2016,2017, we had open interest rate swaps designated as cash flow hedges with maximum terms through 2019. If all open futuresinterest rate swap contracts had been settled on SeptemberJune 30, 2016,2017, we would have recognized a pretax lossgain of $2.3$9.6 million.

If interest rates were to remain at SeptemberJune 30, 20162017 levels, $0.3$3.1 million of deferred lossesgains would be reclassified into earnings during the next twelve months. The actual effect on earnings will be dependent on actual interest rates when the forecasted transactions occur.

Fair value hedges

For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in current earnings. We include the gain or loss on the hedged items (fixed-rate borrowings) in the same line item, interest expense, as the offsetting loss or gain on the related interest rate swaps. As of SeptemberJune 30, 2016,2017, December 31, 20152016 and SeptemberJune 30, 2015,2016, the total notional amounts of our interest rate swaps designated as fair value hedges were $500.0 million, $500.0 million and $250.0 million, zero and zero, respectively.

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.  The counterparties to these agreements are Toronto-Dominion Bank and SMBC Capital Markets, Inc., both of which are major financial institutions.

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.  The counterparties to these agreements are PNC Bank, National Association and Wells Fargo, both of which are major financial institutions.

We have 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. Accordingly, the swap agreements have been recorded at their fair market value of $24.9 million and are included in other long-term liabilities on the accompanying condensed balance sheet as of June 30, 2017, with a corresponding decrease in the carrying amount of the related debt. For the three months ended June 30, 2017 and 2016, $0.7 million and $0.5 million, respectively, and for the six months ended June 30, 2017 and 2016, $1.9 million and $0.5 million, respectively, of income was recorded to interest expense on the accompanying condensed statement of operations related to these swap agreements. No gain or loss has been recorded in earnings as a result of ineffectiveness.

In June 2012, we terminated $73.1 million of interest rate swaps with Wells Fargo that had been entered into on the SunBelt Notes in May 2011. The result was a gain of $2.2 million, which will be recognized through 2017. As of SeptemberJune 30, 2016, $0.22017, $0.1 million of this gain was included in current installments of long-term debt. Pursuant to a note purchase agreement dated December 22, 1997, the SunBelt Chlor Alkali Partnership (SunBelt) sold $97.5 million of Guaranteed Senior Secured Notes due 2017, Series O, and $97.5 million of Guaranteed Senior Secured Notes due 2017, Series G. We refer to these notes as the SunBelt Notes. The SunBelt Notes bear interest at a rate of 7.23% per annum, payable semi-annually in arrears on each June 22 and December 22.

We use interest rate swaps as a means of managing interest expense and floating interest rate exposure to optimal levels. These interest rate swaps are treated as fair value hedges. The accounting for gains and losses associated with changes in fair value of the derivative and the effect on the condensed financial statements will depend on the hedge designation and whether the hedge is effective in offsetting changes in fair value of cash flows of the asset or liability being hedged.


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-performancenonperformance 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, exceedexceeds 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 SeptemberJune 30, 2017, December 31, 2016 and SeptemberJune 30, 2015,2016, this threshold was not exceeded. As of December 31, 2015, the amount recognized in accrued liabilities for cash collateral provided by us to counterparties was $5.6 million. In all instances where we are party to a master netting agreement, we offset the receivable or payable recognized upon payment of cash collateral against the fair value amounts recognized for derivative instruments that have also been offset under such master netting agreements.



FAIR VALUE MEASUREMENTS

Fair value 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’sinstruments’ anticipated life.

Level 3 — Inputs reflected management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration was given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.

We are required to separately disclose assets and liabilities measured at fair value on a recurring basis, from those measured at fair value on a nonrecurring basis. Nonfinancial assets measured at fair value on a nonrecurring basis are intangible assets and goodwill, which are reviewed for impairment annually in the fourth quarter and/or when circumstances or other events indicate that impairment may have occurred.



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

Interest Rate Swaps

The fair value of interestInterest rate swaps was included in other assets, other liabilities and long-term debt as of September 30, 2016. For our cash flow hedges, unrealized gains and losses are included in accumulated other comprehensive loss, net of applicable taxes. The fair value of the interest rate swaps was included in other current assets, current installments of long-term debt and long-term debt as of December 31, 2015 and September 30, 2015. Theseswap 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 Forward Contracts

The fair value of commodity contracts was classified in other current assets and accrued liabilities as of September 30, 2016, and accrued liabilities as of December 31, 2015 and September 30, 2015, with unrealized gains and losses included in accumulated other comprehensive loss, net of applicable taxes. TheseCommodity 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, electricity and natural gas to provide a measure of stability in managing our exposure to price fluctuations.



Foreign Currency Contracts

The fair value of foreignForeign currency contracts was classified within other current assets and accrued liabilities as of September 30, 2016 and December 31, 2015, with gains and losses included in selling and administration expense as thesecontract financial instruments do not meet the criteria to qualifywere valued primarily based on relevant information observable in market transactions involving identical or comparable assets or liabilities including both forward and spot prices for hedge accounting. We had no fair value of foreign currency contracts as of September 30, 2015.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, restricted cash, 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:

Nonrecurring Fair Value Measurements

In addition to assets and liabilities that are recorded at fair value on a recurring basis, we record assets and liabilities at fair value on a nonrecurring basis as required by ASC 820. There were no assets measured at fair value on a nonrecurring basis as of SeptemberJune 30, 2016,2017, December 31, 20152016 and SeptemberJune 30, 2015.2016.

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 U.S. manufacturer of ammunition. For segment reporting purposes, a portion of the Acquired Business’s operating results comprise the newly created Epoxy segment with the remaining operating results combined with Olin’s former Chlor Alkali Products and Chemical Distribution segments to comprise the newly created Chlor Alkali Products and Vinyls segment. 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. 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.

The year-over-year comparisons presented in Management Discussion and Analysis of Financial Condition and Results of Operations are intended to describe material changes in Olin legacy businesses as Olin did not own the Acquired Business until October of 2015.

Executive Summary

2017 Overview

Chlor Alkali Products and Vinyls generated segment income of $53.7$52.8 million and $152.5$140.3 million for the three and ninesix months ended SeptemberJune 30, 2016,2017, respectively. Chlor Alkali Products and Vinyls segment income was higher than the corresponding periods in thecomparable prior year periods due to contributions of the Acquired Chlor Alkali Businesshigher caustic soda and EDC product prices and lower freightoperating costs, partially offset by lower producthigher maintenance costs, unabsorbed fixed manufacturing costs and reduced profit from lost sales associated with the turnarounds and outages. Electricity costs, primarily driven by higher natural gas prices, and lower volumes. The increase in segment income forethylene costs were also higher than the nine months ended September 30, 2016 was also offset by the second quarter 2015 recognition of insurance recoveries associated with our Becancour, Canada chlor alkali facility.comparable prior year periods. Chlor Alkali Products and Vinyls segment income included depreciation and amortization expense of $106.3$106.6 million and $30.4$103.4 million for the three months ended SeptemberJune 30, 20162017 and 2015,2016, respectively, and $311.6$211.2 million and $88.9$205.3 million for the ninesix months ended SeptemberJune 30, 20162017 and 2015,2016, respectively.

For the final nine months of 2016, caustic soda price indices increased resulting in positive product price momentum into 2017. During the first two quarters of 2017, North America caustic soda price contract indices increased an additional $60 per ton. During May 2017, a caustic soda price increase of $70 per ton was announced. This price increase is in the process of being implemented and while the success of this price increase is not yet known, the majority of the benefit, if realized, would impact third and fourth quarters of 2017 results.

Epoxy reported a segment income was $10.3loss of $8.1 million and $18.5$9.3 million for the three and ninesix months ended SeptemberJune 30, 2016,2017, respectively. Epoxy segment results are lower than the comparable prior year periods due to increased raw material costs, primarily associated with benzene and propylene, partially offset by increased product prices. Epoxy segment income included depreciation and amortization expense of $22.6$22.8 million and $67.3$23.0 million for the three and nine months ended SeptemberJune 30, 2017 and 2016, respectively, and $45.2 million and $44.7 million for the six months ended June 30, 2017 and 2016, respectively.

Winchester reported segment income of $36.0$19.0 million and $95.9$44.1 million for the three and ninesix months ended SeptemberJune 30, 2016,2017, respectively. Winchester third quarter and year-to-date segment income increased compared todeclined from the corresponding periods in thecomparable prior year periods primarily due to the impacta lower level of lower commoditycommercial demand for shotshell, pistol and other material costsrifle ammunition and increased volumes. These increases werea less favorable product mix, partially offset by lower product prices and higher operating costs. Winchester’sincreased shipments to military customers. Winchester segment income included depreciation and amortization expense of $4.7$4.5 million and $4.4 million for both the three months ended SeptemberJune 30, 2017 and 2016, and 2015, respectively, and $13.8$9.4 million and $12.7$9.1 million for the ninesix months ended SeptemberJune 30, 20162017 and 2015,2016, respectively.


Financing

On March 21, 2016,9, 2017, we announced that we had made the decision to closeentered into a combined totalnew five-year $1,975.0 million senior credit facility consisting of 433,000 tons of chlor alkali capacity across three separate locations. Associated with this action, we have permanently closeda $600.0 million senior revolving credit facility, which replaced our Henderson, NV chlor alkali plant with 153,000 tons of capacityprevious $500.0 million senior revolving credit facility, and will reconfigure 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 and nine months ended September 30, 2016, we recorded pretax restructuring charges of $4.9a $1,375.0 million and $105.0 million, respectively, associated with these actions. For the nine months ended September 30, 2016, $76.6 millionterm loan facility.

Segment Results

We define segment results as income (loss) before interest expense, interest income, other operating income (expense), and income taxes, and include the operating results of non-consolidated affiliates. Consistent with the guidance in ASC 280, “Segment Reporting” (ASC 280), we have determined it is appropriate to include the operating results of non-consolidated affiliates in the relevant segment financial results. Beginning in the fourth quarter of 2015, we modified our reportable segments due to changes in our organization resulting from the Acquisition. We have three operating segments: Chlor Alkali Products and Vinyls, Epoxy and Winchester. For segment reporting purposes, the Acquired Business’s Global Epoxy operating results comprise the newly created Epoxy segment and the Acquired Chlor Alkali Business operating results combined with our former Chlor Alkali Products and Chemical Distribution segments comprise the newly created Chlor Alkali Products and Vinyls segment. The new reporting structure has been retrospectively applied to the financial results for all periods presented. The three operating segments reflect the organization used by our management for purposes of allocating resources and assessing performance. Chlorine used in our Epoxy segment is transferred at cost from the Chlor Alkali Products and Vinyls segment. Sales and profits are recognized in the Chlor Alkali Products and Vinyls segment for all caustic soda generated and sold by Olin.

Outlook

Net income (loss) in the fourth quarter of 20162017 is projected to be in the $(0.05)$0.70 to $0.05$1.15 per diluted share range, which includes pretax restructuring charges and pretax acquisition-related integration costs oftotaling approximately $20 million and estimated step-up acquisition depreciation and amortization expense of approximately $40$50 million. Net incomeloss in the third quarter of 2016 was $0.11$0.02 per diluted share, which included pretax acquisition-related integration costs of $13.1$48.8 million and pretax restructuring charges of $5.2$112.9 million.

The second half 2017 earnings are forecast to improve compared to first half 2017 levels. The second half 2017 earnings are expected to benefit from reduced maintenance turnaround activity compared to first half 2017 levels. The Chlor Alkali Products and Vinyls segment is forecast to benefit in the second half 2017 from stronger demand across all products, improved caustic soda and chlorine pricing and lower ethylene costs. The second half 2017 Epoxy segment income is expected to benefit from higher product prices and lower raw material costs associated with benzene and propylene than experienced in the first half 2017. In second half 2017, we expect Winchester will benefit from the seasonally strong third quarter commercial ammunition demand and an expected improvement in military sales.

Chlor Alkali Products and Vinyls fourth quarter 20162017 segment income is expected to be slightly lowerhigher compared to the third quarter of 2016 segment income of $53.7$224.9 million reflecting higher chlorine, caustic soda and EDC prices and additional cost synergy realization, partially offset by normal seasonally weaker volumesthe impact of higher maintenance turnaround costs and higher electricity costs, driven by increased natural gas andcosts. We also expect the benefits of lower purchased ethylene prices.prices beginning in the third quarter.

Epoxy fourth quarter 20162017 segment income is expected to be similarequal to the third quarter ofor slightly lower than 2016 segment income of $10.3$15.4 million as improved pricesvolumes and lower expenses for maintenance outagespricing year over year are expected to be more than offset by the higher raw material costs, associated with benzene and seasonally weaker volumes.propylene, and increased turnaround and outage costs.

Winchester fourth quarter 20162017 segment income is expected to be lower thanin the $36.0$95 million to $105 million range, compared to $120.9 million of segment income achieved during the third quarter of 20162016. The forecast for Winchester is primarily driven by normal seasonally weaker demand. However, Winchester fourth quarter 2016 segment income is expectedlower ammunition demand, due primarily to improve comparedan overall reduction in both purchases and inventory reductions by our customers and higher commodity and material costs. We expect the decrease in commercial sales to the $21.8 million of segment income achieved during the fourth quarter of 2015.be partially offset by an increase year over year in military sales. The Oxford, MS relocation project was completed during the second quarter of 2016. TheThis relocation is forecast to reducereduced Winchester's annual operating costs by approximately $40 million in 2016 comparedand, in 2017, we expect the cost savings from the completed project to $35.0 million realized in 2015.reach approximately $45 million.

During the fourth quarter of 2016,2017, we are anticipating environmental expenses in the $2$15 million to $4$20 million range compared to $0.4$9.2 million in the third quarter of 2016. We anticipate that full year 2016 charges for environmental investigatory and remedial activities will be approximately $10 million. We do not believe that there will be recoveries ofexpect to recover any environmental


costs incurred and expensed in prior periods in 2016.2017. In connection with the Acquisition, TDCC has retained liabilities relating to litigation, releases of hazardous materials and violations of environmental law to the extent arising prior to the Closing Date.


We expect qualified defined benefit pension plan income in 20162017 to be higherlower than the 20152016 level by approximately $10 million primarily due to the impact of an actuarial change in the calculation of the plan discount rates, partially offset by the costs associated with the acquired plans. During the third quarter of 2016, we made a discretionary cash contribution to our domestic qualified defined benefit pension plan of $6.0 million. Based on our plan assumptions and estimates, we will not be required to make any additional cash contributions to our domestic qualified defined benefit pension plan in 2016.2017. We do have several international qualified defined benefit pension plans to which we anticipate cash contributions of less than $5 million in 2016.2017.
During the fourth quarter of 2016, we are anticipating pretax restructuring charges of approximately $10 million, associated with the Chlor Alkali Products and Vinyls capacity reduction, the relocation

Environmental Matters

Environmental provisions charged to income, which are included in costs of goods sold, were $0.4$1.8 million and $7.3$2.4 million for the three months ended SeptemberJune 30, 20162017 and 2015,2016, respectively, and $5.5$4.4 million and $13.1$5.1 million for the ninesix months ended SeptemberJune 30, 20162017 and 2015,2016, respectively.

Environmental investigatory and remediation activities spending was associated with former waste disposal sites and past manufacturing operations. Spending in 20162017 for investigatory and remedial efforts, the timing of which is subject to regulatory approvals and other uncertainties, is estimated to be approximately $15$17 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 may incur to protect our interest against those unasserted claims. Our accrued liabilities for unasserted claims amounted to $2.1$0.8 million at SeptemberJune 30, 2016.2017. 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 may 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 operating results in 2015 and are expected tocould be material to operating results in 2016.2017.

In connection with the Acquisition, TDCC retained liabilities relating to releases of hazardous materials and violations of environmental law to the extent arising prior to the Closing Date.

Our condensed balance sheets included liabilities for future environmental expenditures to investigate and remediate known sites amounting to $137.5$135.7 million at SeptemberJune 30, 2016, $138.12017, $137.3 million at December 31, 20152016 and $139.9$138.9 million at SeptemberJune 30, 2015,2016, of which $118.5$118.7 million, $119.1$120.3 million and $120.9$119.9 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.

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 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.


Legal Matters and Contingencies

We, and our subsidiaries, are defendants in various legal actions (including proceedings based on alleged exposures to asbestos) incidental to our past and current business activities. As of SeptemberJune 30, 2016,2017, December 31, 20152016 and SeptemberJune 30, 2015,2016, our condensed balance sheets included liabilities for these legal actions of $22.9$15.9 million, $21.2$13.6 million and $22.7$22.1 million, respectively. These liabilities do not include costs associated with legal representation. Based on our analysis, and considering the inherent uncertainties associated with litigation, we do not believe that it is reasonably possible that these legal actions will materially adversely affect our financial position, cash flows or results of operations. In connection with the Acquisition, TDCC retained liabilities related to litigation to the extent arising prior to the Closing Date. In addition to the aforementioned legal actions, we are party to a dispute relating to a contract termination. The other party to the contract has filed a demand for arbitration alleging, among other things, that Olin breached the related agreement and claimed damages in excess of the amount Olin believes it is obligated for under the contract. 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 effect on our financial results.

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, and, therefore, do not record gain contingencies and recognize income until it is earned and realizable.

For the ninesix months ended SeptemberJune 30, 2016, we recognized an insurance recovery of $11.0 million in other operating income (expense) income for property damage and business interruption related to a 2008 chlor alkali facility incident.



For the nine months ended September 30, 2015, we recognized insurance recoveries of $52.2 million for property damage and business interruption related to the portion of the Becancour, Canada chlor alkali facility that has been shut down since late June 2014. Cost of goods sold was reduced by $9.0 million and selling and administration was reduced by $0.9 million for the reimbursement of costs incurred and expensed in prior periods and other operating (expense) income included a gain of $42.3 million.

As of the Closing Date, an additional $475.0 million was drawn by Olin under this term loan facility which was used to pay fees and expenses of the Acquisition, obtain additional funds for general corporate purposes and refinance Olin’s existing senior term loan facility due in 2019. As of the Closing Date, total borrowings under the term loan facilities were $1,350.0 million. Subsequent to the Closing Date, these senior credit facilities were consolidated into a single $1,850.0 senior credit facility, which includes a $1,350.0 million term loan facility. This new senior credit facility will expire in 2020. The $500.0 million senior revolving credit facilitySenior Revolving Credit Facility includes a $100.0 million letter of credit subfacility. At September 30, 2016, we had $483.5 million available under our $500.0 million senior revolving credit facility because we had issued $16.5 million of letters of credit under the $100.0 million subfacility. The term loan facilityTerm Loan Facility includes amortization payable in equal quarterly installments at a rate of 5.0% per annum for the first two years, increasing to 7.5% per annum for the following year and to 10.0% per annum for the last two years.

Under the new senior credit facility,Amended Senior Credit Facility, we may select various floating ratefloating-rate borrowing options. The actual interest rate paid on borrowings under the senior credit facilityAmended Senior Credit Facility is based on a pricing grid which is dependent upon the leverage ratio as calculated under the terms of the applicable facility for the prior fiscal quarter.  The facility includes various customary restrictive covenants, including restrictions related to the ratio of debt to earnings before interest expense, taxes, depreciation and amortization (leverage ratio) and the ratio of earnings before interest expense, taxes, depreciation and amortization to interest expense (coverage ratio).  Compliance with these covenants is determined quarterly based on the operating cash flows. We were in compliance with all covenants and restrictions under all our outstanding credit agreements as of SeptemberJune 30, 2016 and 2015, and December 31, 2015,2017, and no event of default had occurred that would permit the lenders under our outstanding credit agreements to accelerate the debt if not cured. As of September 30, 2016, there were no covenants or other restrictions that limited our ability to borrow. 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 of June 30, 2017, as a result of our restrictive covenant related to the leverage ratio, the maximum additional borrowings available to us were $547.1 million.  This limitation would restrict our ability to borrow the maximum amounts available under the Senior Revolving Credit Facility and the Receivables Financing Agreement.  As of June 30, 2017, there were no other covenants or other restrictions that would have limited our ability to borrow.

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. The Acquired Business has significantly diversified our product and geographic base, which should enable us to be less cyclical.base. Cash flow from operations is affected by changes in chlorine, caustic soda, EDC and EDCchlorine 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, and a $10 selling price change per ton of chlorine equates to an approximate $10 million annual change in our revenues and pretax profit.

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, payspay 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 is for twelve months beginning on December 31, 2016, December 31, 2017, and December 31, 2018, respectively. The counterparties to the agreements are SMBC Capital Markets, Inc., Wells Fargo, PNC Bank, National Association and Toronto-Dominion Bank. These counterparties 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. We have designated the swaps as cash flow hedges of the risk of changes in interest payments associated with our variable-rate borrowings. Accordingly, the swap agreements have been recorded at their fair market value of $9.6 million and are included in other current assets and other assets on the accompanying condensed balance sheet as of June 30, 2017, with the corresponding gain deferred as a component of other comprehensive loss. For both the three and six months ended June 30, 2017, $0.5 million of income was recorded to interest expense on the accompanying condensed statement of operations related to these swap agreements. No gain or loss has been recorded in earnings as a result of ineffectiveness.

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, payspay us fixed rates.  The counterparties to these agreements are Toronto-Dominion Bank and SMBC Capital Markets, Inc., both of which are major financial institutions.

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. The counterparties to these agreements are PNC Bank, National Association and Wells Fargo, both of which are major financial institutions.

We have 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. Accordingly, the swap agreements have been recorded at their fair market value of $24.9 million and are included in other long-term liabilities on the accompanying condensed balance sheet as of June 30, 2017, with a corresponding decrease in the carrying amount of the related debt. For the three months ended June 30, 2017 and 2016, $0.7 million and $0.5 million, respectively, and for the six months ended June 30, 2017 and 2016, $1.9 million and $0.5 million, respectively, of income was recorded to

interest expense on the accompanying condensed statement of operations related to these swap agreements. No gain or loss has been recorded in earnings as a result of ineffectiveness.

In June 2012, we terminated $73.1 million of interest rate swaps with Wells Fargo that had been entered into on the SunBelt Notes in May 2011.

As of SeptemberJune 30, 2016, $0.22017, $0.1 million of this gain was included in current installments of long-term debt.

In March 2010, we entered into interest rate swaps on $125 million of our underlying fixed-rate debt obligations, whereby we agreed to pay variable rates to a counterparty who, in turn, paid us fixed rates. The counterparty to these agreements was Citibank. In October 2011, we entered into $125 million of interest rate swaps with equal and opposite terms as the $125 million variable interest rate swaps on the 2016 Notes. We have agreed to pay a fixed rate to a counterparty who, in turn, paid us variable rates. The counterparty to these agreements was also Citibank. The result was a gain of $11.0 million on the $125 million variable interest rate swaps, which as of September 30, 2016 has been recognized. In October 2011, we de-designated our $125 million interest rate swaps that had previously been designated as fair value hedges. The $125 million variable interest rate swaps and the $125 million fixed interest rate swaps did not meet the criteria for hedge accounting. All changes in the fair value of these interest rate swaps were recorded currently in earnings.

Off-Balance Sheet Arrangements

Non-cancelable operating leases and purchasing commitments are utilized in our normal course of business for our projected needs. In connection with the Acquisition, certain additional agreements have been entered into with TDCC, including long-term purchase agreements for raw materials.

In August 2016,March 2017, the Financial Accounting Standards Board (FASB) issued Accounting Standards UpdatedUpdate (ASU) 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost” which amends ASC 715 “Compensation—Retirement Benefits.” This update requires the presentation of the service cost component of net periodic benefit cost in the same income statement line item as other employee compensation costs arising from services rendered during the period. The update requires the presentation of the other components of the net period benefit cost separately from the line item that includes the service cost and outside of any subtotal of operating income. The standard is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The guidance in this update is applied on a retrospective basis with earlier application permitted. We are currently evaluating the effect of this update on our consolidated financial statements.

In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment” which amends ASC 350 “Intangibles—Goodwill and Other.” 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 carry 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 standard 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 are currently evaluating the effect of this update on our consolidated financial statements.

In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification“Classification of Certain Cash Receipts and Cash Payments.Payments” which amends ASC 230 “Statement of Cash Flows.” This update will make eight targeted changes to how cash receipts and cash payments are presented and classified in the statement of cash flows. The update is effective for fiscal years beginning after December 15, 2017. The new standard will require adoption on a retrospective basis unless it is impracticable to apply, in which case it would be required to apply the amendments prospectively as of the earliest date practicable. We are currently evaluating the effect of this update on our consolidated financial statements.

In March 2016, the FASB issued ASU 2016-09 “Improvements to Employee Share-Based Payment Accounting,”Accounting” which amends ASC 718 “Compensation—Stock Compensation.” This update will simplify the income tax consequences, accounting for forfeitures and classification on the statements of cash flows of share-based payment arrangements. This standard is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years, with earlier application permitted. We are currently evaluating the effectadopted ASU 2016-09 on January 1, 2017, which was applied prospectively; therefore, prior periods have not been retrospectively adjusted. The adoption of this update did not have a material impact on our consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02 “Leases,” which supersedes ASC 840 “Leases” and creates a new topic, ASC 842 “Leases.” This update requires lessees to recognize a lease liability and a lease asset for all leases, including operating leases, with a term greater than 12 months on its balance sheet. The update also expands the required quantitative and qualitative disclosures surrounding leases. This update is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years, with earlier application permitted. This update will be applied using a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period

presented in the financial statements. We are currently evaluating the effect of this update on our consolidated financial statements.

In NovemberJuly 2015, the FASB issued ASU 2015-17 “Balance Sheet Classification2015-11 “Simplifying the Measurement of Deferred Taxes” (ASU 2015-17),Inventory,” which amends ASC 740.330 “Inventory.” This update requires deferred income tax liabilitiesentities to measure inventory at the lower of cost and assets,net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonable predictable costs of completion, disposal and any related valuation allowance, to be classified as noncurrent on the balance sheet.transportation. This update simplifies the current guidance requiringunder which an entity must measure inventory at the deferred taxes for each jurisdiction to be presented as a net current assetlower of cost or liability and net noncurrent asset or liability.market. This update does not impact inventory measured using LIFO. This update is effective for fiscal years beginning after December 15, 2016 and interim periods within those fiscal years. The guidance may be applied either prospectively or retrospectively, with earlier application permitted.2016. We adopted the provisions of ASU 2015-172015-11 on December 31, 2015,January 1, 2017, which was applied prospectively, and,prospectively; therefore, all prior periods have not been retrospectively adjusted.

In September 2015, the FASB issued ASU 2015-16 “Simplifying the Accounting for Measurement—Period Adjustments” (ASU 2015-16), which amends ASC 805 “Business Combinations.” This update requires that an acquirer in a business combination recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustments are determined. We adopted ASU 2015-16 on January 1, 2016. This update is


applied prospectively to adjustments The adoption of provisional amounts that occur after the effective date with earlier application permitted. Thisthis update did not have a material effectimpact on our consolidated financial statements.

In April 2015, the FASB issued ASU 2015-03 “Simplifying the Presentation of Debt Issuance Costs” (ASU 2015-03) and, in August 2015, the FASB issued ASU 2015-15 “Interest—Imputation of Interest” (ASU 2015-15), which both amend ASC 835-30 “Interest—Imputation of Interest.” These updates require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability while debt issuance costs related to line-of-credit arrangements will continue to be presented as an asset. We adopted ASU 2015-03 and ASU 2015-15 on January 1, 2016 which required retrospective application. As of September 30, 2016, December 31, 2015, and September 30, 2015, debt issuance costs of $28.0 million, $31.4 million and $5.7 million, respectively, were reclassified within our condensed balance sheet from other assets to long-term debt and zero, $1.5 million and $2.2 million, respectively, were reclassified within our condensed balance sheet from other assets to current installments of long-term debt.

In May 2014, the FASB issued ASU 2014-09 “Revenue from Contracts with Customers” (ASU 2014-09), which amends ASC 605 “Revenue Recognition” and creates a new topic, ASC 606 “Revenue from Contracts with Customers” (ASC 606). This update providesSubsequent to the issuance of ASU 2014-09, ASC 606 was amended by various updates that amend and clarify the impact and implementation of the aforementioned standard. These updates provide guidance on how an entity should recognize revenue to depict the transfer of control of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Upon initial application, the provisions of this updatethese updates are required to be applied retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying this update recognized at the date of initial application. This updateThese updates also expandsexpand the disclosure requirements surrounding revenue recorded from contracts with customers. In August 2015, the FASB issued ASU 2015-14 “Revenue from Contracts with Customers,” which amends ASC 606. This update defers theThese updates are effective date of ASU 2014-09 tofor fiscal years, and interim periods within those years, beginning after December 15, 2017, a deferral of one year from2017. We continue to evaluate the previous effective date. In March 2016, the FASB issued ASU 2016-08 “Principal versus Agent Considerations (Reporting Revenue Gross versus Net)” (ASU 2016-08), which amends ASC 606. ASU 2016-08 clarifies the implementation guidance on principal versus agent considerations. In April 2016, the FASB issued ASU 2016-10 “Identifying Performance Obligations and Licensing” (ASU 2016-10), which amends ASC 606. ASU 2016-10 clarifies the implementation guidance on identifying performance obligations. In May 2016, the FASB issued ASU 2016-12 “Narrow-Scope Improvements and Practical Expedients” (ASU 2016-12), which amends ASC 606. ASU 2016-12 addresses narrow-scope improvements to the guidance on collectibility, noncash consideration, and completed contracts at transition. These ASUs apply to all companies that enter into contracts with customers to transfer goods or services. We are currently evaluating the effect ofimpact these updates will have on our consolidated financial statements. Based on the analysis conducted to date, we believe the most significant impact the updates will have will be on our accounting policies and disclosures on revenue recognition. Preliminarily, we do not expect that these updates will materially impact our consolidated financial statements and we have not yet determined the method of initial application we will use.

Item 3. Quantitative and Qualitative Disclosures about Market Risk.

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.

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 SeptemberJune 30, 2016,2017, we maintained open positions on commodity contracts with a notional value totaling $101.3$95.7 million ($63.6101.6 million at December 31, 20152016 and $70.8$55.5 million at SeptemberJune 30, 2015)2016). Assuming a hypothetical 10% increase in commodity prices which are currently hedged, as of SeptemberJune 30, 2016,2017, we would experience a $10.1$9.6 million ($6.410.2 million at December 31, 20152016 and $7.1$5.6 million at SeptemberJune 30, 2015)2016) 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 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 have 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 $16.2$15.6 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. The effect of interest rates on our investing activity is not material to our consolidated financial position, results of operations or cash flows. Our current debt structure is used to fund business operations, and commitments from banks under our senior revolving credit facility, AR Facilities and Receivables Financing Agreement are a source of liquidity. As of SeptemberJune 30, 2016,2017, December 31, 20152016 and SeptemberJune 30, 2015,2016, we had long-term borrowings, including current installments and capital lease obligations, of $3,677.8$3,600.6 million, $3,848.8$3,617.6 million and $662.3$3,695.8 million, respectively, of which $2,255.3$1,723.7 million, $2,305.9$2,238.4 million and $302.2$2,289.0 million at SeptemberJune 30, 2016,2017, December 31, 20152016 and SeptemberJune 30, 2015,2016, respectively, were issued at variable rates.


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, payspay 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 is for twelve months beginning on December 31, 2016, December 31, 2017 and December 31, 2018, respectively. The counterparties to the agreements are SMBC Capital Markets, Inc., Wells Fargo, PNC Bank, National Association and Toronto-Dominion Bank. These counterparties 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.

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, payspay us fixed rates.  The counterparties to these agreements are Toronto-Dominion Bank and SMBC Capital Markets, Inc., both of which are major financial institutions.

In October 2016, we also 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.  The counterparties to these agreements are PNC Bank, National Association and Wells Fargo, both of which are major financial institutions.

In June 2012, we terminated $73.1 million of interest rate swaps with Wells Fargo that had been entered into on the SunBelt Notes in May 2011. The result was a gain of $2.2 million, which will be recognized through 2017. As of SeptemberJune 30, 2016, $0.22017, $0.1 million of this gain was included in current installments of long-term debt.

In March 2010, we entered into interest rate swaps on $125 million of our underlying fixed-rate debt obligations, whereby we agreed to pay variable rates to a counterparty who, in turn, paid us fixed rates. The counterparty to these agreements was Citibank. In October 2011, we entered into $125 million of interest rate swaps with equal and opposite terms as the $125 million variable interest rate swaps on the 2016 Notes. We have agreed to pay a fixed rate to a counterparty who, in turn, paid us variable rates. The counterparty to these agreements was also Citibank. The result was a gain of $11.0 million on the $125 million variable interest rate swaps, which as of September 30, 2016 has been recognized. In October 2011, we de-designated our $125 million interest rate swaps that had previously been designated as fair value hedges. The $125 million variable interest rate swaps and the $125 million fixed interest rate swaps did not meet the criteria for hedge accounting. AllAssuming no changes in the fair value$1,723.7 million of thesevariable-rate debt levels from June 30, 2017, we estimate that a hypothetical change of 100-basis points in the LIBOR interest rates would impact annual interest expense by $17.2 million. A portion of this hypothetical change would be offset by our interest rate swaps were recorded currently in earnings.swaps.

Our interest rate swaps reduced interest expense by $2.6$1.3 million and $2.1$1.2 million for the ninethree months ended SeptemberJune 30, 2017 and 2016, respectively, and 2015,by $2.5 million and $1.9 million for the six months ended June 30, 2017 and 2016, 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 SeptemberJune 30, 20162017. Based on that evaluation, our chief executive officer and chief financial officer have concluded that, as of such date, our disclosure controls and procedures were effective to ensure that information Olin is required to disclose in the reports that it files or submits with the SEC under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the Commission’s rules and forms, and to ensure that information we are required to disclose in such reports is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate to allow timely decisions regarding required disclosure.

There have been no changes in our internal control over financial reporting that occurred during the quarter ended SeptemberJune 30, 20162017, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. However, on October 5, 2015, we acquired from TDCC the Acquired Business. In accordance with the SEC's published guidance, our Annual Report on Form 10-K for the year ending December 31, 2015 did not include consideration of the internal controls of the Acquired Business within management’s assessment of the effectiveness of internal control over financial reporting as of December 31, 2015. We are in the process of integrating the Acquired Business into our overall internal control over financial reporting process and will incorporate the Acquired Business into our annual assessment of internal control over financial reporting as of December 31, 2016.
