Trinseo S.A.
Quarterly Report on Form 10-Q
For the quarterly period ended September 30, 2017
Unless otherwise indicated or required by context, as used in this Quarterly Report on Form 10-Q (“Quarterly Report”), the term “Trinseo” refers to Trinseo S.A. (NYSE: TSE), a public limited liability company (société anonyme) existing under the laws of Luxembourg, and not its subsidiaries. The terms “Company,” “we,” “us” and “our” refer to Trinseo and its consolidated subsidiaries, taken as a consolidated entity. All financial data provided in this Quarterly Report is the financial data of the Company, unless otherwise indicated.
Prior to the formation of the Company, our business was wholly owned by The Dow Chemical Company (together with other affiliates, “Dow”). In June 2010, investment funds advised or managed by affiliates of Bain Capital Partners, LLC (“Bain Capital”) acquired an ownership interest in our business through an indirect ownership interest in us. During 2016, Bain Capital Everest Manager Holding SCA (“the former Parent”), an affiliate of Bain Capital, sold its entire ownership interest in the Company pursuant to the Company’s shelf registration statement filed with the Securities and Exchange Commission (“SEC”).
Definitions of capitalized terms not defined herein appear in the notes to our condensed consolidated financial statements.   The Company may distribute cash to shareholders under Luxembourg law via repayments of equity or an allocation of statutory profits. Since the Company began paying dividends, all distributions have been considered repayments of equity under Luxembourg law.    
Cautionary Note on Forward-Looking Statements
This Quarterly Report contains forward-looking statements including, without limitation, statements concerning plans, objectives, goals, projections, strategies, future events or performance, and underlying assumptions and other statements, which are not statements of historical facts. Forward-looking statements may be identified by the use of words like “expect,” “anticipate,” “intend,” “forecast,” “outlook,” “will,” “may,” “might,” “potential,” “likely,” “target,” “plan,” “contemplate,” “seek,” “attempt,” “should,” “could,” “would” or expressions of similar meaning. Forward-looking statements reflect management’s evaluation of information currently available and are based on our current expectations and assumptions regarding our business, the economy and other future conditions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict. Specific factors that may impact performance or other predictions of future actions have, in many but not all cases, been identified in connection with specific forward-looking statements. Factors that might cause such a difference include, but are not limited to, those discussed in our Annual Report on Form 10-K for the year ended December 31, 2016 (“Annual Report”) filed with the SEC on March 1, 2017 under Part I, Item IA— “Risk Factors”, and elsewhere within this Quarterly Report.
As a result of these or other factors, our actual results may differ materially from those contemplated by the forward-looking statements. They are neither statements of historical fact nor guarantees or assurances of future performance. Therefore, we caution you against relying on these forward-looking statements. The forward-looking statements included in this Quarterly Report are made only as of the date hereof. We undertake no obligation to publicly update or revise any forward-looking statement as a result of new information, future events or otherwise, except as otherwise required by law.
Available Information
Our annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K, and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, are available free of charge through the Investor Relations section of our website, www.trinseo.com, as soon as reasonably practicable after the reports are electronically filed or furnished with the U.S. Securities and Exchange Commission.

TRINSEO S.A.
Notes to Condensed Consolidated Financial Statement  s  
(Dollars in thousands, unless otherwise stated)
(Unaudited)
NOTE 1—BASIS OF PRESENTATION
The unaudited interim condensed consolidated financial statements of Trinseo S.A. and its subsidiaries (the “Company”) as of and for the periods ended September 30, 2017 and 2016 were prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and reflect all adjustments, consisting only of normal recurring adjustments, which, in the opinion of management, are considered necessary for the fair statement of the results for the periods presented. Because they cover interim periods, the statements and related notes to the financial statements do not include all disclosures normally provided in annual financial statements and, therefore, these statements should be read in conjunction with the 2016 audited consolidated financial statements included within the Company’s Annual Report on Form 10-K (“Annual Report”) filed with the Securities and Exchange Commission (“SEC”) on March 1, 2017.
The December 31, 2016 condensed consolidated balance sheet data presented herein was derived from the Company’s December 31, 2016 audited consolidated financial statements, but does not include all disclosures required by GAAP for annual periods.
Certain prior year amounts have been reclassified to conform to the current period presentation. These reclassifications did not have a material impact on the Company’s financial position or results. Refer to Note 14 for further information.
 
NOTE 2—RECENT ACCOUNTING GUIDANCE
In May 2014, the Financial Accounting Standards Board (“FASB”) and the International Accounting Standards Board (“IASB”) jointly issued guidance which clarifies the principles for recognizing revenue and develops a common revenue standard for GAAP and International Financial Reporting Standards (“IFRS”). The core principle of the guidance is that an entity should recognize revenue to depict the transfer 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. Additionally, the FASB has issued certain clarifying updates to this guidance, which the Company will consider as part of our adoption, which will be effective as of January 1, 2018. The Company has completed its scoping assessment for the adoption of this guidance by conducting surveys with relevant stakeholders in the business, including commercial and finance leadership, reviewing a representative sample of revenue arrangements across all businesses, and identifying a set of applicable qualitative revenue recognition changes related to the new standard update.  In completing this phase, the Company has identified its major revenue streams, which are concentrated within individual product sales within each of our reportable segments. As a result of this work, the Company has concluded that it will adopt this new guidance applying the modified retrospective approach.  The Company remains in the process of establishing and documenting key accounting policies, assessing new disclosure requirements, and evaluating impacts on business processes, information technology, and controls resulting from the adoption of this new standard. Additionally, while our final assessment has not been completed, we continue to progress in the quantification of the impacts that this standard will have on our consolidated financial statements and are refining certain estimates that will be used in order to calculate such impacts.
In July 2015, the FASB issued guidance which simplifies the subsequent measurement of inventory by replacing the lower of cost or market test with a lower of cost or net realizable value (“NRV”) test. NRV is calculated as the estimated selling price less reasonably predictable costs of completion, disposal and transportation. The Company adopted this guidance effective January 1, 2017, and the adoption did not have a material impact to the Company’s financial position or results of operations.
In February 2016, the FASB issued guidance related to leases that outlines a comprehensive lease accounting model and supersedes the current lease guidance. The new guidance requires lessees to recognize on the consolidated balance sheets lease liabilities and corresponding right-of-use assets for all leases with terms of greater than 12 months. It also changes the definition of a lease and expands the disclosure requirements of lease arrangements. This new guidance is effective for public companies for annual and interim periods beginning after December 15, 2018, with early adoption permitted. The new guidance must be adopted using a modified retrospective transition, and provides for certain practical expedients. The Company is in the process of assessing the impact on its consolidated financial

statements from the adoption of the new guidance. However, as we are the lessee under various real estate, railcar, and other equipment leases, which we currently account for as operating leases, we anticipate an increase in the recognition of right-of-use assets and lease liabilities as a result of this adoption .  
In August 2016, the FASB issued guidance that aims to eliminate diversity in practice for how certain cash receipts and payments are presented and classified in the consolidated statements of cash flows. Additionally, the FASB has issued further guidance related to the presentation of restricted cash on the consolidated statements of cash flows. The Company adopted this guidance effective September 30, 2017. The most significant impact of this adoption to the Company was the requirement to classify debt prepayment or extinguishment costs, which the Company had historically classified within cash flows from operating activities, as financing cash outflows. This change is reflected in the Company’s condensed consolidated statement of cash flows for the nine months ended September 30, 2017, including the impacts of the Company’s debt refinancing during the third quarter of 2017 (refer to Note 5 for further information). While this adoption was applied using the retrospective approach, there were no transactions during the nine months ended September 30, 2016 that required the condensed consolidated statement of cash flows for that period to be recast.
In January 2017, the FASB issued guidance that revises the definition of a business in order to assist in determining whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. Under the new guidance, fewer transactions are expected to be accounted for as business combinations. The Company adopted this guidance effective January 1, 2017. We expect this adoption could affect conclusions reached for future transactions in several areas, including acquisitions and disposals.
In January 2017, the FASB issued guidance to simplify the accounting for goodwill impairment by removing Step 2 of the test, which requires a hypothetical purchase price allocation. As a result, a goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The Company adopted this guidance effective January 1, 2017, which did not have a material impact to the Company’s financial position or results of operations.
In March 2017, the FASB issued guidance that requires employers to present the service cost component of net periodic benefit cost in the same statement of operations line item as other employee compensation costs arising from services rendered during the period. The other components of net periodic benefit cost are to be presented outside of any subtotal of operating income. This presentation amendment is relevant to the Company and will be applied on a retrospective basis. This guidance is effective for fiscal years and interim periods beginning after December 15, 2017, and early adoption is permitted. The Company is currently assessing the impact of adopting this guidance on its results of operations.
In August 2017, the FASB issued significant amendments to existing hedge accounting guidance. Among other things, this guidance will make more financial and nonfinancial hedging strategies eligible for hedge accounting, amend presentation and disclosure requirements, and change how companies assess effectiveness. This guidance is required for public companies for annual and interim periods beginning after December 15, 2018, with early adoption permitted. The Company is currently assessing the timing and related impact of adopting this guidance on its financial position and results of operations.
NOTE 3—INVESTMENTS IN UNCONSOLIDATED AFFILIATES
During the nine months ended September 30, 2017, the Company had two joint ventures : Americas Styrenics LLC (“Americas Styrenics”, a styrene and polystyrene joint venture with Chevron Phillips Chemical Company LP) and Sumika Styron Polycarbonate Limited (“Sumika Styron Polycarbonate”, a polycarbonate joint venture with Sumitomo Chemical Company Limited). Investments held in the unconsolidated affiliates are accounted for by the equity method. The results of Americas Styrenics are included within its own reporting segment, and the results of Sumika Styron Polycarbonate were included within the Basic Plastics reporting segment until the Company sold its 50% share of the entity in January 2017. Refer to the discussion below for further information about the sale of the Company’s share in Sumika Styron Polycarbonate during the first quarter of 2017.
Both of the unconsolidated affiliates are privately held companies; therefore, quoted market prices for their stock are not available. The summarized financial information of the Company’s unconsolidated affiliates is shown below. This table includes summarized financial information for Sumika Styron Polycarbonate through the date of sale in January 2017.

Americas Styrenics
As of September 30, 2017 and December 31, 2016, respectively, the Company’s investment in Americas Styrenics was $161.9 million and $149.7 million, which was $49.1 million and $71.2 million less than the Company’s 50% share of the underlying net assets of Americas Styrenics . This amount represents the difference between the book value of assets contributed to the joint venture at the time of formation (May 1, 2008) and the Company’s 50% share of the total recorded value of the joint venture’s assets and certain adjustments to conform with the Company’s accounting policies. This difference is being amortized over a weighted average remaining useful life of the contributed assets of approximately 3.1 years as of September 30, 2017. The Company received dividends from Americas Styrenics of $35.0 million and $80.0 million during the three and nine months ended September 30, 2017, respectively, compared to $40.0 million and $100.0 million during the three and nine months ended September 30, 2016, respectively.
Sumika Styron Polycarbonate
On January 31, 2017, the Company completed the sale of its 50% share in Sumika Styron Polycarbonate to Sumitomo Chemical Company Limited for total sales proceeds of approximately $42.1 million. As a result, the Company recorded a gain on sale of $9.3 million during the nine months ended September 30, 2017, which was included within “Other expense (income), net” in the condensed consolidated statement of operations and was allocated entirely to the Basic Plastics segment. In addition, the parties have entered into a long-term agreement to continue sourcing polycarbonate resin from Sumika Styron Polycarbonate to the Company’s Performance Plastics segment.
As of December 31, 2016, the Company’s investment in Sumika Styron Polycarbonate was $41.8 million. Due to the sale in January 2017, the Company no longer has an investment in Sumika Styron Polycarbonate as of September 30, 2017. The Company received dividends from Sumika Styron Polycarbonate of zero and $9.8 million during the three and nine months ended September 30, 2017,  respectively, compared to  zero and $6.2 million during the three and nine months ended September 30, 2016, respectively. The dividend received during the nine months ended September 30, 2017 from Sumika Styron Polycarbonate related to the Company’s proportionate share of earnings for the year ended December 31, 2016.

2020 Senior Credit Facility
On May 5, 2015, the Company entered into a credit agreement which included $825.0 million of senior secured financing (the “2020 Senior Credit Facility”), inclusive of a $325.0 million revolving credit facility maturing in May 2020 (the “2020 Revolving Facility”) and a $500.0 million senior secured term loan B facility maturing in November 2021 (the “2021 Term Loan B”).

issue discount. As a result of this termination, the Company recognized a $0.8 million loss on extinguishment of long-term debt, comprised entirely of the write-off of a portion of the existing unamortized deferred financing fees and unamortized original issue discount related to the 2021 Term Loan B. The remaining unamortized deferred financing fees and unamortized original issue discount for both the 2020 Revolving Facility and 2021 Term Loan B remain capitalized and will be amortized along with new deferred financing fees over the life of the new facilities, discussed in further detail below.
Senior Credit Facility
On September 6, 2017, Trinseo Materials Operating S.C.A. and Trinseo Materials Finance, Inc. (together, the “Borrowers” or “Issuers”), both wholly-owned subsidiaries of the Company, entered into a senior secured credit agreement (the “Credit Agreement”), which provides senior secured financing of up to $1,075.0 million (the “Senior Credit Facility”). The Senior Credit Facility provides for senior secured financing consisting of a (i) $375.0 million revolving credit facility, with a $25.0 million swingline subfacility and a $35.0 million letter of credit subfacility maturing in September 2022 (the “2022 Revolving Facility”) and a (ii) $700.0 million senior secured term loan B facility maturing in September 2024 (the “2024 Term Loan B”). Amounts under the 2022 Revolving Facility are available in U.S. dollars and euros.
The 2024 Term Loan B bears an interest rate of LIBOR plus 2.50%, subject to a 0.00% LIBOR floor. Further, the 2024 Term Loan B requires scheduled quarterly payments in amounts equal to 0.25% of the original principal amount of the 2024 Term Loan B, with the balance to be paid at maturity.
Loans under the 2022 Revolving Facility, at the Borrowers’ option, may be maintained as (a) LIBO rate loans, which bear interest at a rate per annum equal to the LIBO rate plus the applicable margin (as defined in the Credit Agreement), if applicable, or (b) base rate loans which shall bear interest at a rate per annum equal to the base rate plus the applicable margin (as defined in the Credit Agreement).
The Senior Credit Facility is collateralized by a security interest in substantially all of the assets of the Borrowers, and the guarantors thereunder, including Trinseo Materials S.à r.l., certain Luxembourg subsidiaries and certain foreign subsidiaries organized in the United States, The Netherlands, Hong Kong, Singapore, Ireland, Germany and Switzerland.
 The Senior Credit Facility requires the Borrowers and their restricted subsidiaries to comply with customary affirmative, negative and financial covenants, including limitations on their abilities to incur liens; make certain loans and investments; incur additional debt (including guarantees or other contingent obligations); merge, consolidate liquidate or dissolve; transfer or sell assets; pay dividends and other distributions to shareholders or make certain other restricted payments; enter into transactions with affiliates; restrict any restricted subsidiary from paying dividends or making other distributions or agree to certain negative pledge clauses; materially alter the business we conduct; prepay certain other indebtedness; amend certain material documents; and change our fiscal year.
The 2022 Revolving Facility contains a financial covenant that requires compliance with a springing first lien net leverage ratio test. If the outstanding balance under the 2022 Revolving Facility exceeds 30% of the $375.0 million borrowing capacity (excluding undrawn letters of credit up to $10.0 million and cash collateralized letters of credit) at a quarter end, then the Borrowers’ first lien net leverage ratio may not exceed 2.00 to 1.00. As of September 30, 2017, the Company was in compliance with all debt covenant requirements under the Senior Credit Facility.
Fees incurred in connection with the issuance of the 2024 Term Loan B were $12.3 million. Due to a portion of the 2024 Term Loan B meeting the criteria for modification accounting, $1.2 million of these fees were expensed and included within “Other expense (income), net” in the condensed consolidated statement of operations for the three and nine months ended September 30, 2017. The remaining $11.1 million of fees were capitalized and recorded within “Long-term debt, net of unamortized deferred financing fees” on the condensed consolidated balance sheet, to be amortized along with the remaining $8.1 million of unamortized deferred financing fees from the 2021 Term Loan B. Capitalized fees related to the 2024 Term Loan B are being amortized over the 7.0 year term of the facility using the effective interest method.
Fees incurred in connection with the issuance of the 2022 Revolving Facility were $0.8 million and were capitalized and recorded within “Deferred charges and other assets” in the condensed consolidated balance sheets. The new capitalized fees related to the 2022 Revolving Facility (along with $4.0 million of unamortized deferred financing fees from the 2020 Revolving Facility) are being amortized over the 5.0 year term of the facility using the straight-line method. Amortization of deferred financing fees are recorded within “Interest expense, net” in the condensed consolidated statements of operations.

  2022 Senior Notes
In May 2015, the Company issued $300.0 million aggregate principal amount of 6.750% senior notes due May 1, 2022 (the “USD Notes”) and €375.0 million aggregate principal amount of 6.375% senior notes due May 1, 2022 (the “Euro Notes”, and together with the USD Notes, the “2022 Senior Notes”).
On September 7, 2017, using the net proceeds from the issuance of the 2024 Term Loan B, together with the net proceeds from the issuance of the 2025 Senior Notes (defined and discussed below), and available cash, the Company redeemed all outstanding borrowings under the 2022 Senior Notes, totaling $746.0 million in USD-equivalent principal, together with a total combined call premium of $53.0 million (with a redemption price of approximately 106.572% on the USD Notes and a redemption price of approximately 107.459% on the Euro Notes), and accrued and unpaid interest thereon of $17.0 million, using applicable foreign exchange rates.
As a result of this redemption, during the three months ended September 30, 2017, the Company recorded a loss on extinguishment of long-term debt of $64.5 million, which includes the above $53.0 million call premium and an $11.5 million write-off of unamortized deferred financing fees related to the 2022 Senior Notes.
2025 Senior Notes
On August 29, 2017, the Issuers executed an indenture pursuant to which they issued $500.0 million aggregate principal amount of 5.375% senior notes due 2025 (the “2025 Senior Notes”) in a 144A private transaction exempt from the registration requirements of the Securities Act of 1933, as amended. Interest on the 2025 Senior Notes is payable semi-annually on May 3 and November 3 of each year, commencing on May 3, 2018. The 2025 Senior Notes mature on September 1, 2025.
At any time prior to September 1, 2020, the Issuers may redeem the 2025 Senior Notes in whole or in part, at their option, at a redemption price equal to 100% of the principal amount of such notes plus the relevant applicable premium as of, and accrued and unpaid interest to, but not including, the redemption date. At any time and from time to time after September 1, 2020, the Issuers may redeem the 2025 Senior Notes, in whole or in part, at a redemption price equal to the percentage of principal amount set forth below plus accrued and unpaid interest, if any, on the notes redeemed to, but not including, the redemption date:

12-month period commencing September 1 in Year  	 	Percentage	 	
2020	 	102.688	%  	
2021	 	101.792	%  	
2022	 	100.896	%  	
2023 and thereafter	 	100.000	%  	
At any time prior to September 1, 2020, the Issuers may redeem up to 40% of the aggregate principal amount of the 2025 Senior Notes at a redemption price equal to 105.375%, plus accrued and unpaid interest to, but not including, the redemption date, with the aggregate gross proceeds from certain equity offerings.
The 2025 Senior Notes are the Issuers’ senior unsecured obligations and rank equally in right of payment with all of the Issuers’ existing and future indebtedness that is not expressly subordinated in right of payment thereto. The 2025 Senior Notes will be senior in right of payment to any future indebtedness that is expressly subordinated in right of payment thereto and effectively junior to (a) the Issuers’ existing and future secured indebtedness, including the Company’s accounts receivable facility and the Issuers’ Senior Credit Facility (discussed above), to the extent of the value of the collateral securing such indebtedness and (b) all existing and future liabilities of the Issuers’ non-guarantor subsidiaries.
The Indenture contains customary covenants that, among other things, limit the Issuers’ and certain of their subsidiaries’ ability to incur additional indebtedness and guarantee indebtedness; pay dividends on, redeem or repurchase capital stock; make investments; prepay certain indebtedness; create liens; enter into transactions with the Issuers’ affiliates; designate the Issuers’ subsidiaries as Unrestricted Subsidiaries (as defined in the Indenture); and consolidate, merge, or transfer all or substantially all of the Issuers’ assets. The covenants are subject to a number of exceptions and qualifications. Certain of these covenants will be suspended during any period of time that (1) the 2025 Senior Notes have investment grade ratings (as defined in the Indenture) and (2) no default has occurred and is continuing under the Indenture. In the event that the 2025 Senior Notes are downgraded to below an investment grade rating, the Issuers and certain subsidiaries will again be subject to the suspended covenants with respect to future events. As of September 30, 2017, the Company was in compliance with all debt covenant requirements under the Indenture.

Table of Contents

In addition to the significant accounting policies disclosed in Note 2 in our Annual Report, Basis of Presentation and Summary of Significant Accounting Policies, the Company notes the following significant accounting policies related to certain definite-lived intangible assets, for which we had substantial activity during the quarter ended September 30, 2017 as a result of the API Plastics acquisition.
Developed Technology
Acquired developed technology is recorded at fair value upon acquisition and is amortized using the straight-line method over the estimated useful life ranging from 9 years to 15 years. We determine amortization periods for developed technology based on our assessment of various factors impacting estimated useful lives and timing and extent of estimated cash flows of the acquired assets. This includes estimates of expected period of future economic benefit and competitive advantage related to existing processes and procedures at the date of acquisition. Significant changes to any of these factors may result in a reduction in the useful life of these assets.
Customer Relationships
Customer relationships are recorded at fair value upon acquisition and are amortized using the straight-line method over the estimated useful life of 19 years. We determine amortization periods for customer relationships based on our assessment of various factors impacting estimated useful lives and timing and extent of estimated cash flows of the acquired assets. This includes estimates of expected period of future economic benefit and customer retention rates. Significant changes to any of these factors may result in a reduction in the useful life of these assets.
 
NOTE 7—DERIVATIVE INSTRUMENTS
The Company’s ongoing business operations expose it to various risks, including fluctuating foreign exchange rates and interest rate risk. To manage these risks, the Company periodically enters into derivative financial instruments, such as foreign exchange forward contracts and interest rate swap agreements. The Company does not hold or enter into financial instruments for trading or speculative purposes. All derivatives are recorded on the condensed consolidated balance sheets at fair value.
Foreign Exchange Forward Contracts
Certain subsidiaries have assets and liabilities denominated in currencies other than their respective functional currencies, which creates foreign exchange risk. The Company’s principal strategy in managing its exposure to changes in foreign currency exchange rates is to naturally hedge the foreign currency-denominated liabilities on our balance sheet against corresponding assets of the same currency such that any changes in liabilities due to fluctuations in exchange rates are offset by changes in their corresponding foreign currency assets. In order to further reduce its exposure, the Company also uses foreign exchange forward contracts to economically hedge the impact of the variability in exchange rates on our assets and liabilities denominated in certain foreign currencies. These derivative contracts are not designated for hedge accounting treatment.
As of September 30, 2017, the Company had open foreign exchange forward contracts with a notional U.S. dollar equivalent absolute value of $327.9 million. The following table displays the notional amounts of the most significant net foreign exchange hedge positions outstanding as of September 30, 2017.

Indonesian Rupiah	 	$	(29,493)	 	
Swiss Franc	 	$	16,762	 	
Korean Won	 	$	(10,983)	 	
Foreign Exchange Cash Flow Hedges
The Company also enters into forward contracts with the objective of managing the currency risk associated with forecasted U.S. dollar-denominated raw materials purchases by one of its subsidiaries whose functional currency is the euro. By entering into these forward contracts, which are designated as cash flow hedges, the Company buys a designated amount of U.S. dollars and sells euros at the prevailing market rate to mitigate the risk associated with the

16

Table of Contents
fluctuations in the euro-to-U.S. dollar foreign currency exchange rates. The qualifying hedge contracts are marked-to-market at each reporting date and any unrealized gains or losses are included in accumulated other comprehensive income/loss (“AOCI”) to the extent effective, and reclassified to cost of sales in the period during which the transaction affects earnings or it becomes probable that the forecasted transaction will not occur.
Open foreign exchange cash flow hedges as of September 30, 2017 have maturities occurring over a period of 15 months, and have a net notional U.S. dollar equivalent of $196.5 million.
Interest Rate Swaps
As discussed in Note 5, on September 6, 2017, the Company issued the 2024 Term Loan B, which bears an interest rate of LIBOR plus 2.50%, subject to a 0.00% LIBOR floor. In order to reduce the variability in interest payments associated with the Company’s variable rate debt, during the third quarter of 2017, the Company entered into certain interest rate swap agreements to convert a portion of these variable rate borrowings into a fixed rate obligation. These interest rate swap agreements are designated as cash flow hedges, and as such, the contracts are marked-to-market at each reporting date and any unrealized gains or losses are included in AOCI to the extent effective, and reclassified to interest expense in the period during which the transaction affects earnings or it becomes probable that the forecasted transaction will not occur.
As of September 30, 2017, the Company had open interest rate swap agreements with a net notional U.S. dollar equivalent of $200.0 million which had an effective date of September 29, 2017 and mature over a period of five years.
Net Investment Hedge
Through August 31, 2017, the Company had designated a portion ( €280 million) of the original principal amount of the Company’s previous €375.0 million Euro Notes as a hedge of the foreign currency exposure of the Issuers’ net investment in certain European subsidiaries. Effective September 1, 2017, the Company de-designated the Euro Notes as a net investment hedge of the Issuers’ net investment in certain European subsidiaries, as the Euro Notes were redeemed on September 7, 2017 (refer to Note 5 for further information). Through the date of de-designation, this hedge was deemed to be highly effective, and changes in the Euro Notes’ carrying value resulting from fluctuations in the euro exchange rate were recorded as cumulative foreign currency translation loss of $24.1 million within AOCI as of September 30, 2017.
On August 29, 2017, the Issuers executed an indenture pursuant to which they issued the $500.0 million 5.375% 2025 Senior Notes (refer to Note 5 for further information). Subsequently, on September 1, 2017, the Company entered into certain fixed-for-fixed cross currency swaps (“CCS”), swapping USD principal and interest payments on the newly issued 2025 Senior Notes for euro-denominated payments . Under the terms of the CCS, the Company has notionally exchanged $500.0 million at an interest rate of 5.375% for €420 million at a weighted-average interest rate of 3.45% for approximately five years.
Effective September 1, 2017, the Company designated the full notional amount of the CCS (€420 million) as a hedge of the Issuers’ net investment in certain European subsidiaries. As the CCS were deemed to be highly effective hedges, changes in the fair value of the CCS were recorded as cumulative foreign currency translation loss of $7.1 million within AOCI as of September 30, 2017.

The Company recorded losses of $6.5 million and $17.0 million during the three and nine months ended September 30, 2017, respectively, and gains of $1.1 million and $2.1 million during the three and nine months ended September 30, 2016, respectively, from settlements and changes in the fair value of outstanding forward contracts (not designated as hedges) . The gains and losses from these forward contracts offset net foreign exchange transaction gains of $8.2 million and $16.1 million during the three and nine months ended September 30, 2017, respectively, and losses of $1.5 million and $4.1 million during the three and nine months ended September 30, 2016, respectively, which resulted from the remeasurement of the Company’s foreign currency denominated assets and liabilities. The cash settlements of these foreign exchange forward contracts are included within operating activities in the condensed consolidated statement of cash flows.
As of September 30, 2017, the Company had no ineffectiveness related to its derivatives designated as hedging instruments. Further, the Company expects to reclassify in the next twelve months an approximate $10.3 million net loss from AOCI into earnings related to the Company’s outstanding foreign exchange cash flow hedges and interest rate swaps as of September 30, 2017 based on current foreign exchange rates.

NOTE 8—FAIR VALUE MEASUREMENTS
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assets and liabilities measured at fair value are classified using the following hierarchy, which is based upon the transparency of inputs to the valuation as of the measurement date.
Level 1—Valuation is based upon quoted prices (unadjusted) for identical assets or liabilities in active markets.
Level 2—Valuation is based upon quoted prices for similar assets and liabilities in active markets, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.
Level 3—Valuation is based upon other unobservable inputs that are significant to the fair value measurement.

Provision for income taxes for the three and nine months ended September 30, 2016 were $16.0 million, resulting in an effective tax rate of 19.2%, and $66.5 million, resulting in an effective tax rate of 21.7%, respectively.
While the effective tax rate for the three and nine months ended September 30, 2017 and 2016 remained relatively consistent, the rate was impacted by non-recurring items in both periods. 
The effective tax rate for the three and nine months ended September 30, 2017 was impacted by payments made of $10.9 million related to a portion of the fees associated with the call premium paid to retire the Company’s 2022 Senior Notes, which are not anticipated to provide a tax benefit to the Company in the future (refer to Note 5 for further information). The effective tax rate for the three and nine months ended September 30, 2016 was impacted by an impairment charge of $0.3 million and $13.2 million, respectively, for the estimated loss on sale of Trinseo Brazil. Refer to Note 13 for further information.
NOTE 10—COMMITMENTS AND CONTINGENCIES
Environmental Matters
Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated, based on current law, existing technologies and other information. Pursuant to the terms of the agreement associated with the Company’s formation, the pre-closing environmental conditions were retained by Dow and Dow has agreed to indemnify the Company from and against all environmental liabilities incurred or relating to the predecessor periods. No environmental claims have been asserted or threatened against the Company, and the Company is not a potentially responsible party at any Superfund Sites. As of September 30, 2017 and December 31, 2016, the Company had no accrued obligations for environmental remediation and restoration costs.
Inherent uncertainties exist in the Company’s potential environmental liabilities primarily due to unknown conditions, whether future claims may fall outside the scope of the indemnity, changing governmental regulations and legal standards regarding liability, and evolving technologies for handling site remediation and restoration. In connection with the Company’s existing indemnification, the possibility is considered remote that environmental remediation costs will have a material adverse impact on the condensed consolidated financial statements.
Purchase Commitments
In the normal course of business, the Company has certain raw material purchase contracts where it is required to purchase certain minimum volumes at current market prices. These commitments range from 1 to 5 years. In certain raw material purchase contracts, the Company has the right to purchase less than the required minimums and pay a liquidated damages fee, or, in case of a permanent plant shutdown, to terminate the contracts. In such cases, these obligations would be less than the annual commitment as disclosed in the consolidated financial statements included in the Annual Report.
Litigation Matters
From time to time, the Company may be subject to various legal claims and proceedings incidental to the normal conduct of business, relating to such matters as product liability, antitrust/competition, past waste disposal practices and release of chemicals into the environment. While it is impossible at this time to determine with certainty the ultimate outcome of these routine claims, the Company does not believe that the ultimate resolution of these claims will have a material adverse effect on the Company’s results of operations, financial condition or cash flow. Legal costs, including those legal costs expected to be incurred in connection with a loss contingency, are expensed as incurred.

Option Awards
The following are the weighted-average assumptions used within the Black-Scholes pricing model for the Company’s option awards granted during the nine months ended September 30, 2017:

 	 	Nine Months Ended	 	 	
 	 	September 30, 	 	 	
 	    	2017	 	    	
Expected term (in years)	 	5.50	 	 	
Expected volatility	 	35.00	%	 	
Risk-free interest rate	 	2.19	%	 	
Dividend yield	 	2.00	%  	 	
Since the Company’s equity interests were privately held prior to its initial public offering (“IPO”) in June 2014, there is limited publicly available trading history of the Company’s ordinary shares. Until such time that the Company can determine expected volatility based solely on the publicly traded history of its ordinary shares, expected volatility used in the Black-Scholes model for option awards granted is based on a combination of the Company’s historical volatility and similar companies’ stock that are publicly traded. The expected term of option awards represents the period of time that option awards granted are expected to be outstanding. For the option awards granted during the nine months ended September 30, 2017, the simplified method was used to calculate the expected term, given the Company’s limited historical exercise data. The risk-free interest rate for the periods within the expected term of option awards is based on the U.S. Treasury yield curve in effect at the time of grant. The dividend yield is estimated based on historical and expected dividend activity.
Performance Share Units (PSUs)
The Company granted PSUs for the first time during the nine months ended September 30, 2017. The PSUs, which are granted to executives, cliff vest on the third anniversary of the date of grant, generally subject to the executive remaining continuously employed by the Company through the vesting date and achieving certain performance conditions. The number of the PSUs that vest upon completion of the service period can range from 0 to 200 percent of the original grant, subject to certain limitations, contingent upon the Company’s total shareholder return (“TSR”) during the performance period relative to a pre-defined set of industry peer companies. Upon a termination of employment due

23

Table of Contents
to the executive’s death or retirement, or termination in connection with a change in control or other factors prior to the vesting date, the PSUs will vest in full or in part, depending on the type of termination and the achievement of the performance conditions. Dividend equivalents will accumulate on PSUs during the vesting period, will be paid in cash upon vesting, and do not accrue interest. When PSUs vest, shares will be issued from the existing pool of treasury shares. The fair value for PSU awards is computed using a Monte Carlo valuation model.
 
NOTE 13—ACQUISITIONS AND DIVESTITURES
Acquisition of API Plastics
On July 10, 2017, the Company acquired 100% of the equity interests of API Applicazioni Plastiche Industriali S.p.A, or API Plastics, a privately held company. The gross purchase price for the acquisition was $90.5 million, inclusive of $8.4 million of cash acquired, yielding a net purchase price of $82.1 million. These amounts are subject to certain customary post-closing adjustments. During the nine months ended September 30, 2017, the Company paid $79.7 million for this acquisition, leaving an additional $2.4 million of unpaid purchase price accrued, which is expected to be paid during the fourth quarter of 2017. API Plastics, based in Mussolente, Italy, is a manufacturer of soft-touch polymers and bioplastics, such as thermoplastic elastomers (“TPEs”). TPEs can be molded over rigid plastics such as ABS and PC/ABS, which presents opportunities for complementary technology product offerings within our Performance Plastics segment. The acquisition was funded through existing cash on hand.
The Company allocated the purchase price of the acquisition to identifiable assets acquired and liabilities assumed based on their estimated fair values as of the acquisition date. The excess of the purchase price over the aggregate fair values was recorded as goodwill. The Company calculated the fair value of the assets acquired using the income and cost approaches (or a combination thereof). Fair values were determined based on Level 3 inputs including estimated future cash flows, discount rates, royalty rates, growth rates, sales projections, retention rates and terminal values, all of which require significant management judgment.
The purchase price allocation is based upon preliminary information and is subject to change if additional information about the facts and circumstances that existed at the acquisition date becomes available. Additional information is being gathered to finalize these preliminary measurements, particularly with respect to property, plant and equipment, intangible assets, inventory, deferred income taxes and income taxes payable. Further adjustments may be necessary as a result of the Company’s on-going assessment of additional information related to the fair value of assets acquired and liabilities assumed, including goodwill, during the measurement period.

Goodwill (2)	 	 	28,598	 	
Net assets acquired	 	$	90,493	 	

	(1)		The expected lives of the acquired intangible assets are 19 years for customer relationships, 9 years for developed technology, and 3 years for other amortizable intangible assets.	
	(2)		Goodwill consists of expected operating synergies resulting from combining API Plastics with our existing businesses, and is allocated entirely to the Performance Plastics segment. None of the goodwill related to this acquisition will be deductible for income tax purposes.	
During the three and nine months ended September 30, 2017, transaction and integration costs related to advisory and professional fees incurred in conjunction with the API Plastics acquisition were $2.4 million and $3.5 million, respectively, and were included within “Selling, general and administrative expenses” in the condensed consolidated statement of operations. Additionally, during the three and nine months ended September 30, 2017, the Company recorded a $1.3 million non-cash fair value inventory adjustment related to the API Plastics acquisition which was included within “Cost of sales” in the condensed consolidated statement of operations.
Pro forma results of operations information has not been presented, as the effect of the API Plastics acquisition is not material. The operating results of API Plastics are included within the Company's condensed consolidated statement of operations since the acquisition date of July 10, 2017 and were not material to the Company's results for the three and nine months ended September 30, 2017.
Divestiture of Brazil Business
During the second quarter of 2016, the Company signed a definitive agreement to sell Trinseo do Brasil Comercio de Produtos Quimicos Ltda. (“Trinseo Brazil”), its primary operating entity in Brazil, including both a latex binders and automotive business. The sale closed on October 1, 2016.
As a result of this agreement, during the three and nine months ended September 30, 2016, the Company recorded impairment charges for the estimated loss on sale of approximately $0.3 million, and $13.2 million, respectively, within “Other expense (income), net” in the condensed consolidated statement of operations. The $13.2 million charge was allocated as $8.4 million, $4.2 million, and $0.6 million to the Performance Plastics segment, Latex Binders segment, and Corporate, respectively. During the year ended December 31, 2016, the Company received $1.8 million in proceeds

from the sale of these businesses, with an additional $1.7 million received during the nine months ended September 30, 2017.
NOTE 14—SEGMENTS
Effective October 1, 2016, the Company realigned its reporting segments to reflect the new model under which the business is managed and results are reviewed by the chief executive officer, who is the Company’s chief operating decision maker. This change in segments was made to provide increased clarity and understanding around the indicators of profitability and cash flow of the Company. The previous Basic Plastics & Feedstocks segment was split into three new segments: Basic Plastics, which includes polystyrene, copolymers, and polycarbonate; Feedstocks, which represents the Company’s styrene monomer business; and Americas Styrenics, which reflects the equity earnings from its 50%-owned styrenics joint venture. In addition, certain highly differentiated acrylonitrile-butadiene-styrene, or ABS, supplied into Performance Plastics markets, which was previously included in the results of Basic Plastics & Feedstocks, is now included in Performance Plastics. Finally, the Latex segment was renamed to Latex Binders. In conjunction with the segment realignment, the Company also changed its primary measure of segment operating performance from EBITDA to Adjusted EBITDA. Refer to the discussion below for further information about Adjusted EBITDA.
The information in the tables below has been retroactively adjusted to reflect the changes in reporting segments and segment operating performance.
The Latex Binders segment produces styrene-butadiene latex, or SB latex, and other latex polymers and binders, primarily for coated paper and packaging board, carpet and artificial turf backings, as well as a number of performance latex binders applications, such as adhesive, building and construction and the technical textile paper market. The Synthetic Rubber segment produces synthetic rubber products used predominantly in high-performance tires, impact modifiers and technical rubber products, such as conveyer belts, hoses, seals and gaskets. The Performance Plastics segment produces highly engineered compounds and blends and some specialized ABS grades for automotive end markets, as well as consumer electronics, medical, electrical and lighting, collectively consumer essential markets, or CEM. The Basic Plastics segment produces styrenic polymers, including polystyrene, basic ABS, and styrene-acrylonitrile, or SAN, products, as well as polycarbonate, or PC, all of which are used as inputs in a variety of end use markets. The Basic Plastics segment also included the results of our previously 50%-owned joint venture, Sumika Styron Polycarbonate, until the Company sold its share in the entity in January 2017 (refer to Note 3 for further information). The Feedstocks segment includes the Company’s production and procurement of styrene monomer outside of North America, which is used as a key raw material in many of the Company’s products, including polystyrene, SB latex, ABS resins, solution styrene-butadiene rubber, or SSBR, etc. Lastly, the Americas Styrenics segment consists solely of the operations of our 50%-owned joint venture, Americas Styrenics, a producer of both styrene monomer and polystyrene in North America.
Asset, capital expenditure, and intersegment sales information is not reviewed or included with the Company’s reporting to the chief operating decision maker. Therefore, the Company has not disclosed this information for each reportable segment.

(1) The Company’s primary measure of segment operating performance is Adjusted EBITDA, which is defined as income from continuing operations before interest expense, net; provision for income taxes; depreciation and amortization expense; loss on extinguishment of long-term debt; asset impairment charges; gains or losses on the dispositions of businesses and assets; restructuring; acquisition related costs and other items. Adjusted EBITDA is a key metric that is used by management to evaluate business performance in comparison to budgets, forecasts, and prior year financial results, providing a measure that management believes reflects core operating performance by removing the impact of transactions and events that would not be considered a part of core operations. Adjusted EBITDA is useful for analytical purposes; however, it should not be considered an alternative to the Company’s reported GAAP results, as there are limitations in using such financial measures. Other companies in the industry may define Adjusted EBITDA differently than the Company, and as a result, it may be difficult to use Adjusted EBITDA, or similarly named financial measures, that other companies may use to compare the performance of those companies to the Company’s segment performance.

NOTE 17—EARNINGS PER SHARE
Basic earnings per ordinary share (“basic EPS”) is computed by dividing net income available to ordinary shareholders by the weighted average number of the Company’s ordinary shares outstanding for the applicable period. Diluted earnings per ordinary share (“diluted EPS”) is calculated using net income available to ordinary shareholders divided by diluted weighted-average ordinary shares outstanding during each period, which includes unvested RSUs, option awards, and PSUs. Diluted EPS considers the impact of potentially dilutive securities except in periods in which there is a loss because the inclusion of the potential ordinary shares would have an anti-dilutive effect.
The following table presents basic EPS and diluted EPS for the three and nine months ended September 30, 2017 and 2016, respectively.

* Refer to Note 12 for discussion of RSUs, option awards, and PSUs granted to certain Company directors and employees. The number of anti-dilutive shares that have been excluded in the computation of diluted earnings per share were 0.2 million for the both the three and nine months ended September 30, 2017, respectively, and zero for both the three and nine months ended September 30, 2016, respectively.

During the three and nine months ended September 30, 2017, the Company executed a refinancing of its debt, including:
	·		Issuing $500.0 million aggregate principal amount of 5.375% 2025 Senior Notes;	
	·		Entering the new Senior Credit Facility, which consists of the $375.0 million 2022 Revolving Facility and the $700.0 million 2024 Term Loan B, bearing an interest rate of LIBOR plus 2.50%, subject to a 0.00% LIBOR floor; and	
	·		Using the net proceeds from the above along with available cash to redeem all outstanding indebtedness under its existing 2022 Senior Notes and to repay all outstanding borrowings under its existing 2020 Senior Credit Facility, together with a $53.0 million call premium on the 2022 Senior Notes, accrued and unpaid interest, and fees and other expenses related to the refinancing.	
Additionally, on September 1, 2017, the Company entered into certain fixed-for-fixed cross currency swaps (CCS), swapping USD principal and interest payments on the newly issued 2025 Senior Notes for euro-denominated payments .

Three Months Ended - September 30, 2017 vs. September 30, 2016
Net Sales
Of the 17% increase, 13% was due to higher selling prices primarily from the pass through of higher raw material costs, including higher styrene and butadiene costs to customers across our segments. Additionally, 2% of the increase was due to slightly higher sales volume, as increases in Performance Plastics and Basic Plastics sales volume were mostly offset by decreases in Latex Binders and Synthetic Rubber sales volume. A favorable currency impact increased sales by 3% as the euro strengthened in comparison to the U.S. dollar on a quarter-to-date basis. Offsetting these increases in net sales was a net 1% decrease related to portfolio adjustments.

comparison to the U.S. dollar on a quarter-to-date basis. Slightly higher fixed costs resulted in a 1% increase which was mostly offset by a decrease in cost of sales related to portfolio adjustments.
Gross Profit
This increase was primarily due to increased margins per unit sold, primarily within Feedstocks, due to unplanned industry production outages, including the impact of Hurricane Harvey, as well as within Basic Plastics and Latex Binders.
Selling, General and Administrative Expenses
The majority of the $8.2 million decrease is due to a reduction in restructuring charges of $14.7 million, noting $14.3 million in asset impairment charges recorded in the prior year as a result of our decision to cease manufacturing operations at our latex facility in Livorno, Italy. This reduction is partially offset by additional transaction and integration related costs of $2.4 million related to the API Plastics acquisition and $3.6 million of asset impairment charges on certain long-lived assets within the Performance Plastics segment during the third quarter of 2017. Refer to Notes 13 and 15 in the condensed consolidated financial statements for further information.
Equity in Earnings of Unconsolidated Affiliates
Equity earnings increased in 2017, as equity earnings from Americas Styrenics increased from $34.3 million in 2016 to $43.8 million in 2017, primarily due to higher styrene margin which was partially offset by lower polystyrene margin. Additionally, equity earnings from Sumika Styron Polycarbonate decreased from $2.4 million in 2016 to zero in 2017, as the Company completed the sale of its 50% share in the entity to Sumitomo Chemical Company Limited in January 2017, and therefore did not have an ownership interest in the joint venture during the three months ended September 30, 2017. Refer to Note 3 in the condensed consolidated financial statements for further information.
Interest Expense, Net
Interest expense was relatively flat, noting that the Company’s debt refinancing during the third quarter of 2017 did not occur until later in the period, and therefore did not have a significant impact on interest expense for the three months ended September 30, 2017. Refer to Note 5 in the condensed consolidated financial statements for further information.
Loss on Extinguishment of Long-Term Debt
Loss on extinguishment of long-term debt was $65.3 million for the three months ended September 30, 2017, which related to the Company’s debt refinancing during the third quarter of 2017. This amount was comprised of a $53.0 million call premium paid to retire the Company’s 2022 Senior Notes and a $11.5 million write-off of unamortized deferred financing fees related to these notes, as well as the write-off of $0.8 million of unamortized deferred financing fees and unamortized original issue discount related to the termination of the Company’s 2021 Term Loan B.
Other Expense (Income), net
Other income, net for the three months ended September 30, 2017 was less than $0.1 million, which consisted primarily of net foreign exchange transaction gains of approximately $1.7 million offset by other expenses of $1.7 million. Included in the net foreign exchange transaction gains of $1.7 million were foreign exchange transactions gains of $8.2 million, primarily due to the remeasurement of our euro denominated payables due to the relative changes in rates between the U.S. dollar and the euro during the period, partially offset by losses of $6.5 million from our foreign exchange forward contracts. Other expenses of $1.7 million primarily includes $1.2 million of fees incurred in conjunction with the Company’s debt refinancing during the third quarter of 2017.
Other expense, net for the three months ended September 30, 2016 was $1.1 million, which consisted primarily of net foreign exchange transaction losses of approximately $0.4 million, additional impairment charges of $0.3 million for the estimated loss on sale of the Company’s latex and automotive businesses in Brazil, and other expenses. Refer to Note 13 in the condensed consolidated financial statements for further information.   Included in the net foreign exchange losses of $0.4 million were foreign exchange transaction losses of $1.5 million, primarily due to the remeasurement of

our euro denominated payables due to the relative changes in rates between the U.S. dollar and the euro during the period, partially offset by gains of $1.1 million from our foreign exchange forward contracts.
Provision for Income Taxes
Provision for income taxes for the three months ended September 30, 2017 totaled $8.3 million resulting in an effective tax rate of 20.0%. Provision for income taxes for the three months ended September 30, 2016 totaled $16.0 million resulting in an effective tax rate of 19.2%.
The decrease in provision for income taxes was primarily driven by the $41.8 million decrease in income before income taxes,  due predominantly to costs incurred related to the Company’s debt refinancing that occurred during the third quarter of 2017. Refer to Note 5 in the condensed consolidated financial statements for further information.  
Nine Months Ended - September 30, 2017 vs. September 30, 2016
Net Sales
Of the 20% increase, 20% was due to higher selling prices primarily from the pass through of higher raw material costs, including higher styrene and butadiene costs to customers across our segments. Additionally, 1% of the increase was due to slightly higher sales volume, as increases in Performance Plastics and Synthetic Rubber sales volume were partially offset by decreases in Latex Binders and Basic Plastics sales volume. Offsetting these increases in net sales was a net 1% decrease related to portfolio adjustments.
Cost of Sales
Of the 22% increase, 23% was attributable to higher prices for raw materials, primarily related to styrene monomer and butadiene, and an additional 1% of the increase was due to increased sales volume, primarily in Performance Plastics and Synthetic Rubber. Portfolio adjustments resulted in a 1% decrease in cost of sales, which was mostly offset by a slight increase in fixed costs.
Gross Profit
The increase was primarily attributable to higher year-to-date margins per unit sold, especially within the Latex Binders and Feedstocks segments, due to more favorable market conditions. Higher sales volume in Synthetic Rubber and Performance Plastics was partially offset by lower sales volume in Basic Plastics and Latex Binders, as well as margin compression in Performance Plastics due to higher raw material costs.
Selling, General and Administrative Expenses
The $1.0 million year-over-year increase is comprised of several offsetting factors. Restructuring expenses decreased by $12.5 million, noting $16.1 million in asset impairment and other charges recorded in the prior year as a result of our decision to cease manufacturing operations at our latex facility in Livorno, Italy, partially offset by $2.9 million in charges in the current year related to the upgrade and replacement of the Company’s compounding facility in Terneuzen, The Netherlands. Offsetting the decrease in restructuring expenses were increased costs incurred supporting growth initiatives of approximately $4.0 million, transaction and integration related costs of $3.5 million related to the API Plastics acquisition, and $3.6 million of asset impairment charges on certain long-lived assets within the Performance Plastics segment. Refer to Notes 13 and 15 in the condensed consolidated financial statements for further information.
Equity in Earnings of Unconsolidated Affiliates
Equity earnings decreased in 2017, as equity earnings from Americas Styrenics decreased from $104.9 million in 2016 to $92.2 million in 2017, primarily due to the planned and extended first quarter styrene outage at its St. James, LA facility, including lower margins on second quarter sales of styrene purchased during the outage. Additionally, equity earnings from Sumika Styron Polycarbonate decreased from $5.4 million in 2016 to $0.8 million in 2017, as the Company completed the sale of its 50% share in the entity to Sumitomo Chemical Company Limited in January 2017,

Table of Contents
and therefore did not have an ownership interest in the joint venture for the majority of the nine months ended September 30, 2017. Refer to Note 3 in the condensed consolidated financial statements for further information.
Interest Expense, Net
This slight decrease was primarily attributable to lower deferred financing fee amortization recorded into interest expense from our Accounts Receivable Securitization Facility. As the Company’s debt refinancing during the third quarter of 2017 did not occur until later in the period, there was no significant impact on interest expense for the nine months ended September 30, 2017. Refer to Note 5 in the condensed consolidated financial statements for further information.
Loss on Extinguishment of Long-Term Debt
Loss on extinguishment of long-term debt was $65.3 million for the nine months ended September 30, 2017, which related to the Company’s debt refinancing during the third quarter of 2017. This amount was comprised of a $53.0 million call premium paid to retire the Company’s 2022 Senior Notes and a $11.5 million write-off of unamortized deferred financing fees related to these notes, as well as the write-off of $0.8 million of unamortized deferred financing fees and unamortized original issue discount related to the termination of the Company’s 2021 Term Loan B.
Other Expense (Income), net
Other income, net for the nine months ended September 30, 2017 was $6.2 million, which primarily includes a $9.3 million gain related to the sale of the Company’s 50% share in Sumika Styron Polycarbonate in January 2017 (refer to Note 3 in the condensed consolidated financial statements for further information). Additionally, net foreign exchange transaction losses for the period were $0.9 million, which included $16.1 million of foreign exchange transaction gains primarily due to the remeasurement of our euro denominated payables due to the relative changes in rates between the U.S. dollar and the euro during the period, more than offset by $17.0 million of losses from our foreign exchange forward contracts. Additionally, other expenses included $1.2 million of fees incurred in conjunction with the Company’s debt refinancing during the third quarter of 2017.
Other expense, net for the nine months ended September 30, 2016 was $16.7 million, which includes an impairment charge for the estimated loss on sale of our latex and automotive businesses in Brazil of approximately $13.2 million. Refer to Note 13 in the condensed consolidated financial statements for further information. Adding to these losses were net foreign exchange transaction losses of $2.0 million. Included in these net losses of $2.0 million were foreign exchange transactions losses of $4.1 million, primarily due to the remeasurement of our euro denominated payables due to the relative changes in rates between the U.S. dollar and the euro during the period, partially offset by gains of $2.1 million from our foreign exchange forward contracts.
Provision for Income Taxes
Provision for income taxes for the nine months ended September 30, 2017 totaled $56.4 million resulting in an effective tax rate of 21.1%. Provision for income taxes for the nine months ended September 30, 2016 totaled $66.5 million resulting in an effective tax rate of 21.7%.
The decrease in provision for income taxes was primarily driven by the $39.2 million decrease in income before income taxes, due predominantly to costs incurred related to the Company’s debt refinancing that occurred during the third quarter of 2017. Refer to Note 5 in the condensed consolidated financial statements for further information.
Outlook
Overall, we expect continued strong fundamental business performance through the remainder of 2017. European styrene monomer margin over raw materials is forecast to decline in the fourth quarter from third quarter levels by approximately $110 per ton, on average, as offline capacity begins to come back online. Additionally, in the fourth quarter, the Company will open a new SSBR pilot plant in Germany. This incremental capacity will allow for more

Three Months Ended - September 30, 2017 vs. September 30, 2016
Net sales increased 10% from the prior year, due mostly to higher selling prices, which resulted in a 15% increase. These higher selling prices were primarily due to the pass through of higher butadiene and styrene costs to our customers. Offsetting this increase was a 4% decrease due to lower sales volume to the North America paper and carpet markets, as well as an additional 4% decrease due to portfolio adjustments. A favorable currency impact increased net sales by 2% as the euro strengthened in comparison to the U.S. dollar on a quarter-to-date basis.
The increase in Adjusted EBITDA of 8% was due to margin improvements of $9.8 million, a 33% increase, primarily due to better market conditions in Asia, partially offset by lower sales volume, which resulted in a 12% decrease. Increased fixed costs resulted in a 9% decrease in Adjusted EBITDA, while portfolio adjustments resulted in an additional 4% decrease in Adjusted EBITDA.
Nine Months Ended - September 30, 2017 vs. September 30, 2016 
Of the 24% increase in net sales, 29% was due to higher selling prices, primarily due to the pass through of higher butadiene and styrene costs to our customers. Offsetting this increase was a 4% decrease due to portfolio adjustments and a 1% decrease in sales volume.
Adjusted EBITDA increased by $35.2 million, or 50%, year-over-year primarily due to margin improvements of $44.3 million, or 63%, particularly in Asia, resulting from favorable market conditions. Partially offsetting these margin improvements was a 7% decrease due to lower sales volume, primarily within the North America and European paper and carpet markets, and a 3% decrease due to increased fixed costs. Portfolio adjustments resulted in a 4% decrease to Adjusted EBITDA.

Three Months Ended - September 30, 2017 vs. September 30, 2016
Net sales increased 5% from the prior year, with higher selling prices contributing to 9% of the increase, primarily resulting from the pass through of higher butadiene and styrene costs to customers. A favorable currency impact increased net sales by 5% as the euro strengthened in comparison to the U.S. dollar on a quarter-to-date basis. Offsetting these increases was an 8% decrease due to lower sales volume, primarily from customer destocking in SSBR.
The majority of the overall $34.1 million decrease in Adjusted EBITDA was due to unfavorable raw material timing, due to rapidly declining butadiene prices, which led to a $23.9 million decrease related to margin as higher cost raw materials purchased in previous periods were reflected in our cost of goods sold during the third quarter. Additionally, lower sales volume, primarily from customer destocking in SSBR, contributed to a $7.2 million decrease.
Nine Months Ended - September 30, 2017 vs. September 30, 2016
Net sales increased 40% from the prior year, with higher selling prices contributing to 34% of the increase, primarily resulting from the pass through of higher butadiene and styrene costs to customers. Additionally, 6% of the increase was due to higher sales volume which was a result of higher customer demand for SSBR and ESBR, as well as higher sales of Ni-PBR, noting decreased production in the prior year to allow for Nd-PBR trials.
The majority of the overall $13.4 million decrease in Adjusted EBITDA was primarily due to unfavorable raw material timing resulting from declining butadiene prices during the period, net of favorable price lag, which resulted in a 14% decrease due to lower margins. Higher fixed costs, primarily from growth initiatives, resulted in a 9% decrease in Adjusted EBITDA. These decreases were partially offset by higher sales volume primarily related to higher demand for SSBR, ESBR, and Ni-PBR, which resulted in a 6% increase in Adjusted EBITDA.
Performance Plastics Segment
Our Performance Plastics segment consists of compounds and blends and some specialized ABS grades. We are a producer of highly engineered compounds and blends for automotive end markets, as well as consumer electronics, medical, electrical and lighting, collectively referred to as consumer essential markets.

Three Months Ended - September 30, 2017 vs. September 30, 2016
Of the 18% increase in net sales, 7% was due to higher selling prices due to the pass through of higher raw material costs to our customers, as well as a 7% increase due to increased sales volume as a result of higher volumes sold to the automotive market in North America and the consumer electronics market in Asia. A favorable currency impact increased net sales by 3% as the euro strengthened in comparison to the U.S. dollar on a quarter-to-date basis with an additional 1% increase due to portfolio adjustments.
The slight decrease in Adjusted EBITDA was due to several offsetting factors. A 14% increase in Adjusted EBITDA was due to increased sales volume to the automotive market in North America and the consumer electronics market in Asia, with an additional 2% net increase due to portfolio adjustments. Offsetting these increases was a 12% decrease due to margin compression from increased costs of raw materials, such as polycarbonate, not all of which were able to be passed through to our customers. Additionally, an inventory build during 2016 resulted in increased fixed cost absorption in the prior year, contributing to an overall 8% decrease in Adjusted EBITDA in the current year related to fixed costs.
Nine Months Ended - September 30, 2017 vs. September 30, 2016
Of the 10% increase in net sales, 5% was due to higher selling prices due to the pass through of higher raw material costs to our customers, as well as an 8% increase due to increased sales volume, primarily related to higher sales to the automotive markets in Europe and North America and the consumer electronics market in Asia. Portfolio adjustments resulted in a 2% decrease in net sales.
The overall decrease in Adjusted EBITDA of $23.9 million was the result of several factors. Unfavorable raw material timing led to lower margins for the period. In addition, the Company experienced margin compression from increased costs of raw materials, not all of which were able to be passed through to our customers. These two factors contributed to a combined 33% decrease in Adjusted EBITDA compared to the prior year. Additionally, increased fixed costs contributed to a 6% decrease in Adjusted EBITDA. Partially offsetting these decreases was a 13% increase due to increased sales volume growth to the automotive markets in Europe and North America and a 3% increase due to portfolio adjustments.
Basic Plastics Segment
The Basic Plastics segment produces styrenic polymers, including polystyrene, basic ABS, and SAN products, as well as PC, all of which are used as inputs in a variety of end use markets. The Basic Plastics segment also included the results of our previously 50%-owned joint venture Sumika Styron Polycarbonate prior to its sale in January 2017. Refer to Note 3 in the condensed consolidated financial statements for further information.

Three Months Ended - September 30, 2017 vs. September 30, 2016
Of the 22% increase in net sales, 10% was due to higher selling prices due to the pass through of higher styrene costs to customers and 7% was due to higher polystyrene and copolymer sales volume. Additionally, a favorable currency impact increased net sales by 4% as the euro strengthened in comparison to the U.S. dollar on a quarter-to-date basis.
Adjusted EBITDA increased 23%, or $7.9 million, of which 21% was due to higher margins, particularly in polycarbonate due to very tight market conditions. An additional 13% increase was due to higher sales volume, particularly in copolymers. Partially offsetting these increases was a 6% decrease due to increased fixed costs, which includes start-up costs incurred related to our new ABS capacity in Asia, and a 7% decrease due to portfolio adjustments, which included the impact of the sale of Sumika Styron Polycarbonate during the first quarter of 2017.
Nine Months Ended - September 30, 2017 vs. September 30, 2016
Of the 12% increase in net sales, 16% was due to higher selling prices due to the pass through of increased raw material costs to customers, primarily styrene. This increase was partially offset by a 3% decrease due to lower sales volume, primarily related to lower polystyrene sales in Asia, as we have increased our focus on higher margin business.
The slight decrease in Adjusted EBITDA was partly due to several offsetting factors. Firstly, an 11% increase in Adjusted EBITDA was due to higher year-to-date margins, primarily within ABS and polycarbonate. However, this increase was offset by lower sales volume, which resulted in a decrease of 4%, primarily related to Europe and Asia polystyrene sales, with competitor supply outages in Europe in the prior year and with an increased focus on higher margins in Asia. Higher fixed costs, including start-up costs incurred related to our new ABS capacity in Asia, contributed to an additional decrease of 4%. Portfolio adjustments resulted in a 4% decrease in Adjusted EBITDA, due to the sale of Sumika Styron Polycarbonate during the first quarter of 2017.
Feedstocks Segment
The Feedstocks segment includes the Company’s production and procurement of styrene monomer outside of North America, which is used as a key raw material in many of the Company’s products, including polystyrene, SB latex, ABS resins, SSBR, etc.

Table of Contents

The increase in Adjusted EBITDA was primarily due to higher styrene margin due to unplanned industry production outages, including the impact of Hurricane Harvey, which resulted in a $33.1 million increase in Adjusted EBITDA, slightly offset by a $1.4 million decrease due to higher maintenance-related fixed costs.
Nine Months Ended - September 30, 2017 vs. September 30, 2016
The 32% increase in net sales was almost entirely due to the pass through of higher styrene prices, which contributed to 30% of the increase. Higher styrene-related sales volume also resulted in a 3% increase in net sales.
The increase in Adjusted EBITDA was primarily due to higher margins as a result of favorable market conditions, which resulted in a 38% increase in Adjusted EBITDA, slightly offset by a 7% decrease due to higher maintenance-related fixed costs.
Americas Styrenics Segment
The Americas Styrenics segment consists solely of the operations of our 50%-owned joint venture, Americas Styrenics, a producer of both styrene monomer and polystyrene in North America. Styrene monomer is a basic building block of plastics and a key input to many of the Company’s products, as well as a key raw material for the production of polystyrene. Major applications for the polystyrene products Americas Styrenics produces include appliances, food packaging, food service disposables, consumer electronics and building and construction materials.

* The results of this segment are comprised entirely of earnings from Americas Styrenics, our equity method investment. As such, Adjusted EBITDA related to this segment is included within “Equity in earnings of unconsolidated affiliates” in the consolidated statements of operations.
Three Months Ended - September 30, 2017 vs. September 30, 2016
The increase in Adjusted EBITDA was primarily due to higher styrene sales volume, including impacts from a stronger export market, as well as higher styrene margin as a result of unplanned industry supply outages, including the impact of Hurricane Harvey, which was offset by lower polystyrene margin.
Nine Months Ended – September 30, 2017 vs. September 30, 2016
The decrease in Adjusted EBITDA was primarily due to the planned first quarter styrene outage at the Americas Styrenics St. James, LA facility, which was extended in order to complete repairs on critical equipment. The facility came back online at full production in early April 2017. As a result of this extended outage, the Company incurred an unfavorable impact of approximately $23 million to Adjusted EBITDA.
Non-GAAP Performance Measures
We present Adjusted EBITDA as a non-GAAP financial performance measure, which we define as income from continuing operations before interest expense, net; provision for income taxes; depreciation and amortization expense; loss on extinguishment of long-term debt; asset impairment charges; gains or losses on the dispositions of businesses and assets; restructuring; acquisition related costs and other items. In doing so, we are providing management, investors, and credit rating agencies with an indicator of our ongoing performance and business trends, by removing the impact of transactions and events that we would not consider a part of our core operations.
There are limitations to using the financial performance measures such as Adjusted EBITDA. This performance measure is not intended to represent net income or other measures of financial performance. As such, it should not be used as an alternative to net income as an indicator of operating performance. Other companies in our industry may define Adjusted EBITDA differently than we do. As a result, it may be difficult to use this or similarly-named financial measures that other companies may use, to compare the performance of those companies to our performance. We

compensate for these limitations by providing a reconciliation of this performance measure to our net income, which is determined in accordance with GAAP.
Adjusted EBITDA is calculated as follows for the three and nine months ended September 30, 2017 and 2016, respectively:

	(a)		EBITDA is a non-GAAP financial performance measure that we refer to in making operating decisions because we believe it provides our management as well as our investors and credit agencies with meaningful information regarding the Company’s operational performance. We believe the use of EBITDA as a metric assists our board of directors, management and investors in comparing our operating performance on a consistent basis. Other companies in our industry may define EBITDA differently than we do. As a result, it may be difficult to use EBITDA, or similarly-named financial measures that other companies may use, to compare the performance of those companies to our performance. We compensate for these limitations by providing reconciliations of our EBITDA results to our net income, which is determined in accordance with GAAP.	
	(b)		Net gain on disposition of businesses and assets during the nine months ended September 30, 2017 relates primarily to the sale of our 50% share in Sumika Styron Polycarbonate to Sumitomo Chemical Company Limited, for which the Company recorded a gain on sale of $9.3 million during the period. Refer to Note 3 in the condensed consolidated financial statements for further information. During the nine months ended September 30, 2016, the Company recorded an impairment charge for the estimated loss on sale of our primary operating entity in Brazil, which includes both latex and automotive businesses, of approximately $13.2 million. Refer to Note 13 in the condensed consolidated financial statements for further information.	
	(c)		Restructuring and other charges for the three and nine months ended September 30, 2017 primarily relate to employee termination benefit and decommissioning charges incurred in connection with the decision to cease manufacturing activities at our latex binders manufacturing facility in Livorno, Italy, as well as employee termination benefit charges and contract termination charges related to the upgrade and replacement of the Company’s compounding facility in Terneuzen, The Netherlands. Refer to Note 15 in the condensed consolidated financial statements for further information. Restructuring and other charges for the three and nine months ended September 30, 2016 relate primarily to $16.1 million in charges incurred in connection with the Livorno, Italy action noted above, consisting of an impairment charge for unrecoverable net book value of property, plant, and equipment and other assets, as well as employee and contract termination charges. The remaining restructuring charges for the three and nine months ended September 30, 2016 relate to employee termination benefit and decommissioning charges incurred in connection with the Allyn’s Point shutdown within our latex binders business, as well as employee termination benefit charges related to the elimination of certain corporate functions as a result of the sale of our latex and automotive businesses in Brazil.

Note that the accelerated depreciation charges incurred as part of both the upgrade and replacement of the Company’s compounding facility in Terneuzen, The Netherlands as well as the Allyn’s Point shutdown are included within the “Depreciation and amortization” caption above, and therefore are not included as a separate adjustment within this caption.
	(d)		Acquisition transaction and integration costs for the three and nine months ended September 30, 2017 relate to advisory and professional fees and a non-cash fair value inventory adjustment incurred in conjunction with the Company’s acquisition of API Plastics, which closed in July 2017. Refer to Note 13 in the condensed consolidated financial statements for further information.	
	(e)		Asset impairment charges for the three and nine months ended September 30, 2017 relate to the impairment of certain long-lived assets within the Company’s Performance Plastics segment.	
	(f)		Other items for the three and nine months ended September 30, 2017 primarily relate to fees incurred in conjunction with the Company’s debt refinancing which was completed during the third quarter of 2017. Other items for the three and nine months ended September 30, 2016 primarily relate to fees incurred in conjunction with the Company’s secondary offerings completed during these periods.	
Liquidity and Capital Resources
Cash Flows
The table below summarizes our primary sources and uses of cash for the nine months ended September 30, 2017 and 2016, respectively. We have derived the summarized cash flow information from our unaudited financial statements.

Operating Activities
Net cash provided by operating activities during the nine months ended September 30, 2017 totaled $194.8 million, inclusive of $80.0 million in dividends from Americas Styrenics, as well as dividends from Sumika Styron Polycarbonate, $8.9 million of which were classified as operating activities, with the remaining $0.9 million classified as investing activities. Refer to Note 3 in the condensed consolidated financial statements for further information. Net cash used in operating assets and liabilities for the nine months ended September 30, 2017 totaled $160.3 million, due primarily to increases in accounts receivable of $92.8 million and inventories of $57.3 million, respectively. The increases in accounts receivable and inventories were primarily due to increased raw material prices.
Net cash provided by operating activities during the nine months ended September 30, 2016 totaled $324.7 million, due primarily to earnings for the period. Also impacting cash flows from operating activities for the period was $100.0 million in dividends from Americas Styrenics. Net cash used in operating assets and liabilities for the nine months ended September 30, 2016 totaled $38.0 million, due primarily to increases in accounts receivable of $30.2 million and inventories of $27.6 million, respectively,  offset by an increase in accounts payable and other current liabilities of $23.1 million. The increase in accounts receivable was primarily due to higher net sales during the third quarter of 2016, compared to the fourth quarter of 2015, due primarily to increasing raw material prices as well as volume increases.  The increase in inventory was primarily due to increasing raw material prices,  and the increase in accounts payable and other current liabilities is primarily due to timing of payments, as well as increases in prices for raw materials purchases.

Investing Activities
Net cash used in investing activities for the nine months ended September 30, 2017 totaled $141.5 million, resulting from capital expenditures of $108.9 million and cash paid to acquire API Plastics of $79.7 million during the period, net of cash acquired (refer to Note 13 in the condensed consolidated financial statements for further information). Offsetting these uses of cash were primarily proceeds received of $42.1 million from the sale of the Company’s 50% share in Sumika Styron Polycarbonate to Sumitomo Chemical Company Limited.
Net cash used in investing activities for the nine months ended September 30, 2016 totaled $77.7 million, primarily from capital expenditures of $82.7 million during the period, a significant portion of which related to our project to upgrade our legacy ERP environment to the latest version of SAP.  Partially offsetting these capital expenditures were dividends received from Sumika Styron Polycarbonate during the period, $4.8 million of which were classified as investing activities on the condensed consolidated statement of cash flows, with the remaining $1.4 million classified as operating activities.
Financing Activities
Net cash used in financing activities during the nine months ended September 30, 2017 totaled $210.2 million. The most significant activity during the period related to the third quarter debt refinancing, which included net proceeds of $1,200.0 million from the issuance of our 2024 Term Loan B and our 2025 Senior Notes, offset by the retirement of our existing 2021 Term Loan B and 2022 Senior Notes totaling $1,238.5 million and deferred financing fees paid in conjunction with the refinancing of $19.2 million. As a result of the redemption of the 2022 Senior Notes, the Company paid a call premium of $53.0 million during the period. Additionally, the Company paid $65.2 million related to the repurchase of ordinary shares and also paid $42.2 million of dividends. Partially offsetting these uses of cash was $8.3 million of proceeds received from the exercise of option awards.
Net cash used in financing activities during the nine months ended September 30, 2016 totaled $211.7 million. This activity was primarily due to  $194.1 million of payments related to the repurchase of ordinary shares during the period and $13.9 million of dividends paid, as well as $3.8 million of principal payments related to our 2021 Term Loan B.
 
Free Cash Flow
We use Free Cash Flow as a non-GAAP measure to evaluate and discuss the Company’s liquidity position and results. Free Cash Flow is defined as cash from operating activities, less capital expenditures. We believe that Free Cash Flow provides an indicator of the Company’s ongoing ability to generate cash through core operations, as it excludes the cash impacts of various financing transactions as well as cash flows from business combinations that are not considered organic in nature. We also believe that Free Cash Flow provides management and investors with a useful analytical indicator of our ability to service our indebtedness, pay dividends (when declared), and meet our ongoing cash obligations.
Free Cash Flow is not intended to represent cash flows from operations as defined by GAAP, and therefore, should not be used as an alternative for that measure. Other companies in our industry may define Free Cash Flow differently than we do. As a result, it may be difficult to use this or similarly-named financial measures that other companies may use, to compare the liquidity and cash generation of those companies to our own. We compensate for these limitations by providing a reconciliation to cash provided by operating activities, which is determined in accordance with GAAP.

Refer to the discussion above for significant impacts to cash provided by operating activities for the nine months ended September 30, 2017 and 2016, respectively.
Capital Resources and Liquidity
We require cash principally for day-to-day operations, to finance capital investments and other initiatives, to purchase materials, to service our outstanding indebtedness, and to fund dividend payments to our shareholders. Our sources of liquidity include cash on hand, cash flow from operations, and amounts available under the Senior Credit Facility and the Accounts Receivable Securitization Facility.
As of September 30, 2017 and December 31, 2016, we had $1,201.5 million and $1,187.4 million, respectively, in outstanding indebtedness and $949.8 million and $890.7 million, respectively, in working capital. In addition, as of September 30, 2017 and December 31, 2016, we had $106.9 million and $88.8 million of foreign cash and cash equivalents on our balance sheet, respectively, all of which is readily convertible into other foreign currencies, including the U.S. dollar. Our intention is not to permanently reinvest our foreign cash and cash equivalents. Accordingly, we record deferred income tax liabilities related to the unremitted earnings of our subsidiaries.
As noted in Note 5 of the condensed consolidated financial statements, the Company completed a debt refinancing during the third quarter of 2017, the results of which are reflected in the table below. For definitions of capitalized terms not included herein, refer to the Annual Report .  
The following table outlines our outstanding indebtedness as of September 30, 2017 and December 31, 2016 and the associated interest expense, including amortization of deferred financing fees. Effective interest rates for the borrowings included in the table below are for the nine months ended September 30, 2017 and the year ended December 31, 2016. Note that the effective interest rates below exclude the impact of deferred financing fee amortization.

Our Senior Credit Facility includes the 2022 Revolving Facility, which matures in September 2022, and has a

46

Table of Contents
borrowing capacity of $375.0 million. As of September 30, 2017, the Company had no outstanding borrowings, and had $357.2 million (net of $17.8 million outstanding letters of credit) of funds available for borrowing under the 2022 Revolving Facility.  Further, as of September 30, 2017, the Borrowers are required to pay a quarterly commitment fee in respect of any unused commitments under the 2022 Revolving Facility equal to 0.375% per annum.
We also continue to maintain our Accounts Receivable Securitization Facility set to mature in May 2019, under which our borrowing capacity is $200.0 million. As of September 30, 2017, there were no amounts outstanding under the Accounts Receivable Securitization Facility, with approximately $148.8 million of funds available for borrowing under this facility, based on the pool of eligible accounts receivable.
Our other borrowing arrangements include our $700.0 million 2024 Term Loan B (maturing in September 2024), which requires scheduled quarterly payments in amounts equal to 0.25% of the original principal, and our 2025 Senior Notes (maturing in September 2025), which totaled $500.0 million as of September 30, 2017.
The Senior Credit Facility and Indenture contain certain customary affirmative, negative and financial covenants. As of September 30, 2017, the Company was in compliance with all of these debt covenant requirements. Refer to Note 5 of the condensed consolidated financial statements for further information on the details of these covenant requirements.
Our ability to raise additional financing and our borrowing costs may be impacted by short- and long-term debt ratings assigned by independent rating agencies, which are based, in significant part, on our performance as measured by certain credit metrics such as interest coverage and leverage ratios.
We and our subsidiaries, affiliates or significant shareholders may from time to time seek to retire or purchase our outstanding debt through cash purchases in the open market, privately negotiated transactions, exchange transactions or otherwise. Such repurchases or exchanges, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.
Trinseo Materials Operating S.C.A. and Trinseo Materials Finance, Inc. (the “Issuers” of our 2025 Senior Notes and “Borrowers” under our Senior Credit Facility) are dependent upon the cash generation and receipt of distributions and dividends or other payments from our subsidiaries and joint venture in order to satisfy their debt obligations. There are no known significant restrictions by third parties on the ability of subsidiaries of the Company to disburse or dividend funds to the Issuers and the Borrowers in order to satisfy these obligations. However, as the Company’s subsidiaries are located in a variety of jurisdictions, the Company can give no assurances that its subsidiaries will not face transfer restrictions in the future due to regulatory or other reasons beyond our control.
The Senior Credit Facility and Indenture also limit the ability of the Borrowers and Issuers, respectively, to pay dividends or make other distributions to Trinseo S.A., which could then be used to make distributions to shareholders. During the nine months ended September 30, 2017, the Company declared total dividends of $1.02 per ordinary share (totaling $45.8 million), of which $16.8 million remains accrued as of September 30, 2017, the majority of which will be paid in October 2017. These dividends are well within the available capacity under the terms of the restrictive covenants contained in the Senior Credit Facility and Indenture. Further, significant additional capacity continues to be available under the terms of these covenants to support expected future dividends to shareholders, should the Company continue to declare them.
The Company’s cash flow generation in recent years has been strong, with positive cash flows expected to continue for full year 2017. We believe that funds provided by operations, our existing cash and cash equivalent balances, borrowings available under our 2022 Revolving Facility and borrowings available under our Accounts Receivable Securitization Facility will be adequate to meet planned operating and capital expenditures for at least the next 12 months under current operating conditions. Nevertheless, our ability to generate future cash and to pay our indebtedness and fund other liquidation needs is subject to certain risks described under “Part I, Item 1A-“Risk Factors” of our Annual Report.
Contractual Obligations and Commercial Commitments
Other than the impact of the Company’s debt refinancing during the third quarter of 2017, which included the issuance of our 2025 Senior Notes and 2024 Term Loan B, accompanied by the retirement of our 2022 Senior Notes and the 2021 Term Loan B (discussed in Note 5 to the condensed consolidated financial statements), there have been no material revisions outside the ordinary course of business to our contractual obligations as described within “Management’s

Discussion and Analysis of Financial Condition and Results of Operations – Contractual Obligations and Commercial Commitments” within our Annual Report.
Critical Accounting Policies and Estimates
Our unaudited interim condensed consolidated financial statements are based on the selection and application of significant accounting policies. The preparation of unaudited interim condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and revenues and expenses at the date of and during the reporting period. Actual results could differ from those estimates. However, we are not currently aware of any reasonably likely events or circumstances that would result in materially different results.
We describe our significant accounting policies in Note 2, Basis of Presentation and Summary of Significant Accounting Policies, of the Notes to Consolidated Financial Statements included in our Annual Report, while we discuss our critical accounting policies and estimates in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” within our Annual Report. There have been no material revisions to the critical accounting policies as filed in our Annual Report,  other than the impacts to our accounting policies from our acquisition of API Plastics during the third quarter of 2017, discussed within Note 6 to the condensed consolidated financial statements, and the following addition to our critical accounting estimates as a result of this transaction.
 
Business Combinations
Acquisitions that qualify as a business combination are accounted for using the purchase accounting method. Amounts paid for an acquisition are allocated to the assets acquired and liabilities assumed based on their fair value as of the date of acquisition. Goodwill is recorded as the difference in the fair value of the acquired assets and liabilities assumed (net assets acquired) and the purchase price. Goodwill is not amortized, but is reviewed for impairment annually as of October 1 st , or when events or changes in the business environment indicate that the carrying value of a reporting unit may exceed its fair value. Refer to the critical accounting policies and estimates in “ Management’s Discussion and Analysis of Financial Condition and Results of Operations” within our Annual Report for further information regarding the Company’s goodwill impairment testing methodology and significant judgments and assumptions applied.
Under the purchase accounting method, the Company completes valuation procedures for an acquisition, often with the assistance of third-party valuation specialists, to determine the fair value of the assets acquired and liabilities assumed. These valuation procedures require management to make assumptions and apply significant judgment to estimate the fair value of the assets acquired and liabilities assumed. If the estimates or assumptions used should significantly change, the resulting differences could materially affect the fair value of net assets.
Specifically, the calculation of the fair value of tangible assets, including property, plant and equipment, utilizes the cost approach, which computes the cost to replace the asset, less accrued depreciation resulting from physical deterioration, functional obsolescence and external obsolescence. The calculation of the fair value of identified intangible assets is determined using cash flow models following the income approach. Significant inputs include estimated future cash flows, discount rates, royalty rates, growth rates, sales projections, retention rates, and terminal values, all of which require significant management judgment. Definite-lived intangible assets, which are primarily comprised of developed technology, customer relationships, manufacturing capacity rights, and software, are amortized over their estimated useful lives using the straight-line method and are assessed for impairment whenever events or changes in circumstances indicate the carrying value of the asset may not be recoverable. Recoverability of assets that will continue to be used in ongoing operations is measured by comparing the carrying value of the asset to the forecasted undiscounted future cash flows related to the asset. In the event the carrying value of the asset exceeds its undiscounted future cash flows and the carrying value is not considered recoverable, impairment may exist. An impairment loss, if any, is measured as the excess of the asset’s carrying value over its fair value, generally based on a discounted future cash flow method, independent appraisals, etc.

Recent Accounting Pronouncements
We describe the impact of recent accounting pronouncements in Note 2 to our condensed consolidated financial statements, included elsewhere within this Quarterly Report.
Item 3. Quantitative and Qualitativ  e Disclosures about Market Risk
As discussed in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” within our Annual Report, we are exposed to changes in interest rates and foreign currency exchange rates as well as changes in the prices of certain commodities that we use in production. There have been no material changes in our exposure to market risks from the information provided within our Annual Report and our Quarterly Report on Form 10-Q filed with the SEC on August 3, 2017.
Item 4. Controls and Procedures   
Evaluation of Disclosure Controls and Procedures
Our management is responsible for establishing and maintaining internal controls designed to provide reasonable assurance that information required to be disclosed by us in our reports that we file or submit under the Exchange Act (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended) is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, with the participation of our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures. Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the Company’s disclosure controls and procedures as of September 30, 2017. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures as of the end of the period covered by this Quarterly Report were effective to provide the reasonable level of assurance described above.
Changes in Internal Control over Financial Reporting
As discussed in Note 13 to the condensed consolidated financial statements, in July 2017, the Company completed the acquisition of API Plastics. As permitted by the SEC, management has elected to exclude this acquisition from its assessment of the effectiveness of its internal control over financial reporting as of December 31, 2017. The Company began to integrate API Plastics into its internal control over financial reporting structure subsequent to the acquisition date and expects to complete this integration by June 2018.
Aside from the API Plastics changes discussed above, there have been no additional changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) that occurred during the quarter ended September 30, 2017 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. 
PART II — OTHER INFORMATION   
Item 1. Legal Proceeding  s  
From time to time we may be subject to various legal claims and proceedings incidental to the normal conduct of business, relating to such matters as product liability, antitrust, competition, waste disposal practices, release of chemicals into the environment and other matters that may arise in the ordinary course of our business. We currently believe that there is no litigation pending that is likely to have a material adverse effect on our business. Regardless of the outcome, legal proceedings can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.
