Quarterly Report on Form 10-Q

For the quarterly period ended June 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 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 Securities and Exchange Commission (“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

TRINSEO S.A.

Notes to Condensed Consolidated Financial Statements  

(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 June 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 12 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 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 process, information technology, and controls, and determining the quantitative impact resulting from the adoption of this new standard. 

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

9

receipts and payments are presented and classified in the consolidated statements of cash flows. This guidance is effective for public companies for annual and interim periods beginning after December 15, 2017, with early adoption permitted. This guidance must be adopted using a retrospective approach, and provides for certain practical expedients. Additionally, the FASB has issued further guidance related to the presentation of restricted cash on the consolidated statements of cash flows. While the Company continues to assess the timing and related impact of adopting this guidance on its consolidated statement of cash flows, the most significant expected impact on the Company’s financial statements will be the requirement to classify debt prepayment or extinguishment costs as financing cash outflows, as opposed to the Company’s prior classification of these types of costs within operating activities.

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 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.

NOTE 3—INVESTMENTS IN UNCONSOLIDATED AFFILIATES

During the six months ended June 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.

As of June 30, 2017 and December 31, 2016, respectively, the Company’s investment in Americas Styrenics was $153.1 million and $149.7 million, which was $52.3 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 3.3 years as of June 30, 2017. The Company received dividends from Americas Styrenics of $37.5 

10

million and $45.0 million during the three and six months ended June 30, 2017, respectively, compared to $30.0 million and $60.0 million during the three and six months ended June 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 six months ended June 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 June 30, 2017. The Company received dividends from Sumika Styron Polycarbonate of zero and $9.8 million during the three and six months ended June 30, 2017,  respectively, compared to  zero and $6.2 million during the three and six months ended June 30, 2016, respectively. The dividend received during the six months ended June 30, 2017 from Sumika Styron Polycarbonate related to the Company’s proportionate share of earnings for the year ended December 31, 2016.

NOTE 6—DERIVATIVE INSTRUMENTS

The Company’s ongoing business operations expose it to various risks, including fluctuating foreign exchange rates. To manage these risks, the Company periodically enters into derivative financial instruments such as foreign exchange forward contracts. 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.

12

As of June 30, 2017, the Company had open foreign exchange forward contracts with a notional U.S. dollar equivalent absolute value of $302.1 million. The following table displays the notional amounts of the most significant net foreign exchange hedge positions outstanding as of June 30, 2017.

	June 30,

Chinese Yuan	$	(74,647)
Indonesian Rupiah	$	(33,617)
Swiss Franc	$	18,686
Japanese Yen	$	(7,706)

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 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 June 30, 2017 have maturities occurring over a period of 18 months, and have a net notional U.S. dollar equivalent of $255.0 million.

Net Investment Hedge

The Company’s outstanding debt includes €375.0 million of Euro Notes (refer to Note 5 for details). As of June 30, 2017, the Company has designated a portion (€280 million) of the principal amount of these Euro Notes as a hedge of the foreign currency exposure of the Issuers’ net investment in certain European subsidiaries. As this debt was deemed to be a highly effective hedge, changes in the Euro Notes’ carrying value resulting from fluctuations in the euro exchange rate were recorded as cumulative foreign currency translation loss of $10.2 million within AOCI as of June 30, 2017.

The Company recorded losses of $8.8 million and $10.5 million during the three and six months ended June 30, 2017, respectively, and losses of $2.1 million and gains of $1.0 million during the three and six months ended June 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 $7.3 million and $7.9 million during the three and six months ended June 30, 2017, respectively, and gains of $2.3 million and losses of $2.6 million during the three and six months ended June 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 June 30, 2017, the Company has no ineffectiveness related to its foreign exchange cash flow hedges. Further, the Company expects to reclassify in the next twelve months an approximate $4.7 million net loss from AOCI into earnings related to the Company’s outstanding cash flow hedges as of June 30, 2017 based on current foreign exchange rates.

Forward contracts are entered into with a limited number of counterparties, each of which allows for net settlement of all contracts through a single payment in a single currency in the event of a default on or termination of any one contract. As such, in accordance with the Company’s accounting policy, we record these foreign exchange forward contracts on a net basis by counterparty within the condensed consolidated balance sheet. Information regarding the gross amounts of the Company’s derivative instruments and the amounts offset in the condensed consolidated balance sheets is as follows:

	Gross Amounts		Gross Amounts		Net Amounts

Refer to Notes 7 and 14 of the condensed consolidated financial statements for further information regarding the fair value of the Company’s derivative instruments and the related changes in AOCI.

NOTE 7—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.

The following table summarizes the basis used to measure certain assets and liabilities at fair value on a recurring basis in the condensed consolidated balance sheets as of June 30, 2017 and December 31, 2016.

	June 30, 2017

Total fair value	$	—	$	12,171	$	—	$	12,171

The Company uses an income approach to value its derivative instruments, utilizing discounted cash flow techniques, considering the terms of the contract and observable market information available as of the reporting date. Significant inputs to the valuation for foreign exchange forward contracts and foreign exchange cash flow hedges are obtained from broker quotations or from listed or over-the-counter market data, and are classified as Level 2 in the fair value hierarchy.

Fair Value of Debt Instruments

The following table presents the estimated fair value of the Company’s outstanding debt not carried at fair value as of June 30, 2017 and December 31, 2016, respectively:

	As of		As of
	June 30, 2017		December 31, 2016
2022 Senior Notes
USD Notes	$	318,750	$	315,000
Euro Notes		456,187		424,437
2021 Term Loan B		494,596		498,041
Total fair value	$	1,269,533	$	1,237,478

The fair value of the Company’s Term Loan B, USD Notes, and Euro Notes (each Level 2 securities) is determined using over-the-counter market quotes and benchmark yields received from independent vendors.

There were no other significant financial instruments outstanding as of June 30, 2017 and December 31, 2016.

NOTE 8—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 June 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

16

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.

NOTE 9—PENSION PLANS AND OTHER POSTRETIREMENT BENEFITS

The components of net periodic benefit costs for all significant plans were as follows:

	Three Months Ended				Six Months Ended

As of June 30, 2017 and December 31, 2016, the Company’s benefit obligations included primarily in “Other noncurrent obligations” in the condensed consolidated balance sheets were $211.7 million and $195.8 million, respectively. The net periodic benefit costs are recognized in the condensed consolidated statement of operations as “Cost of sales” and “Selling, general and administrative expenses.”

The Company made cash contributions and benefit payments to unfunded plans of approximately $5.0 million and $10.2 million during the three and six months ended June 30, 2017, respectively. The Company expects to make additional cash contributions, including benefit payments to unfunded plans, of approximately $5.5 million to its defined benefit plans for the remainder of 2017.

NOTE 10—STOCK-BASED COMPENSATION

Refer to the Annual Report for definitions of capitalized terms not included herein and further background on the Company’s stock-based compensation programs included in the tables below.  

The following table summarizes the Company’s stock-based compensation expense for the three and six months ended June 30, 2017 and 2016 as well as unrecognized compensation cost as of June 30, 2017:

The following table summarizes awards granted and the respective weighted-average grant date fair value for the six months ended June 30, 2017:

	Six Months Ended
	June 30, 2017
	Awards Granted		Weighted Average Grant Date Fair Value per Award
RSUs		110,117	$	70.87
Options		191,565		20.61
PSUs		50,937		75.74

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 six months ended June 30, 2017:

	Six Months Ended
	June 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 six months ended June 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.

18

Performance Share Units (PSUs)

The Company granted PSUs for the first time during the six months ended June 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 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 11—DIVESTITURES

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 six months ended June 30, 2016, the Company recorded impairment charges for the estimated loss on sale of approximately $12.9 million within “Other expense (income), net” in the condensed consolidated statement of operations. These charges, which are subject to certain post-closing settlement activities, were allocated as $8.6 million, $4.0 million, and $0.3 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 $1.5 million received during the six months ended June 30, 2017.

NOTE 12—SEGMENTS

Effective October 1, 2016, the Company realigned its reporting segments to reflect the new model under which the business is now 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

19

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 15—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 six months ended June 30, 2017 and 2016, respectively.

	Three Months Ended				Six Months Ended

* Refer to Note 10 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 0.3 million and 0.2 million for the three and six months ended June 30, 2017, respectively, and zero million and zero million for the three and six months ended June 30, 2016, respectively.

NOTE 16—SUBSEQUENT EVENTS

On July 10, 2017, the Company completed the acquisition of API Applicazioni Plastiche Industriali S.p.A, or API Plastics, for a purchase price of $83.8 million, net of cash acquired, subject to certain customary post-closing adjustments. API Plastics, based in Mussolente, Italy, is a manufacturer of soft-touch polymers and bioplastics, such as thermoplastic elastomers (“TPEs”). TPEs are often 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.

Three Months Ended - June 30, 2017 vs. June 30, 2016

Net Sales

Of the 18% increase, 21% 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 Synthetic Rubber, Performance Plastics, and Feedstocks sales volume were mostly offset by decreases in Latex Binders and Basic Plastics sales volume. Offsetting these increases in net sales was a 2% decrease related to the prior year divestiture of our business in Brazil, as well as a 2% decrease due to an unfavorable currency impact across our segments, as the euro weakened in comparison to the U.S. dollar.

Cost of Sales

Of the 28% increase, 33% was attributable to higher prices for raw materials, primarily butadiene and styrene monomer. This increase was partially offset by a 1% decrease due to sales volume mix, as well as a 2% decrease due to the prior year divestiture of our business in Brazil. In addition, a decrease of 3% was due to a favorable currency impact across our segments, as the euro weakened in comparison to the U.S. dollar.

Gross Profit

This decrease was primarily due to unfavorable raw material timing impacts, net of a favorable price lag impact, which contributed significantly to lower margins within Feedstocks, Basic Plastics, and Synthetic Rubber.  Partially offsetting these timing impacts were higher sales volume in Synthetic Rubber and Performance Plastics as well as higher margins within Latex Binders. Other contributing factors to the overall decrease were margin compression in Performance Plastics and lower sales volume in Basic Plastics and Latex Binders.  

Selling, General and Administrative Expenses

The majority of the increase is due to costs from additional resources supporting growth initiatives as well as transaction and integration costs incurred in connection with the Company’s acquisition of API Plastics, which closed in July 2017. Additionally, restructuring charges increased $0.7 million, primarily related to the Company’s decision in August 2016 to cease manufacturing activities at our latex facility in Livorno, Italy, as well as charges related to the upgrade and replacement of the Company’s compounding facility in Terneuzen, The Netherlands, which was announced in March 2017. Refer to Notes 16 and 13, respectively, in the condensed consolidated financial statements for further information.

26

Equity in Earnings of Unconsolidated Affiliates

Equity earnings decreased in 2017, as equity earnings from Americas Styrenics decreased from $37.7 million in 2016 to $29.9 million in 2017, primarily due to lower margins on second quarter sales of styrene purchased during the first quarter maintenance-related outage at the St. James, LA, facility in a decreasing price environment. Additionally, equity earnings from Sumika Styron Polycarbonate decreased from $0.9 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 June 30, 2017. Refer to Note 3 in the condensed consolidated financial statements for further information.

Interest Expense, Net

The slight decrease in interest expense was primarily attributable to lower deferred financing fee amortization recorded into interest expense from our Accounts Receivable Securitization Facility.

Other Expense (Income), net

Other expense, net for the three months ended June 30, 2017 was $2.0 million, which consisted primarily of net foreign exchange transaction losses of approximately $1.5 million and other expenses of $0.5 million. Included in these net losses of $1.5 million were foreign exchange transactions gains of $7.3 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, more than offset by losses of $8.8 million from our foreign exchange forward contracts.

Other expense, net for the three months ended June 30, 2016 was $12.9 million, which includes an impairment charge for the estimated loss on sale of our latex and automotive businesses in Brazil of approximately $12.9 million, as well as other expenses of $0.2 million. Refer to Note 11 in the condensed consolidated financial statements for further information. These losses were slightly offset by net foreign exchange transaction gains of approximately $0.2 million. Included in this net gain of $0.2 million were foreign exchange transactions gains of $2.3 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 $2.1 million from our foreign exchange forward contracts.

Provision for Income Taxes

Provision for income taxes for the three months ended June 30, 2017 totaled $18.8 million resulting in an effective tax rate of 23.8%. Provision for income taxes for the three months ended June 30, 2016 totaled $28.6 million resulting in an effective tax rate of 23.0%.

The decrease in provision for income taxes was primarily due to the $45.4 million decrease in income before income taxes.

Six Months Ended - June 30, 2017 vs. June 30, 2016

Net Sales

Of the 21% increase, 24% 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 Synthetic Rubber, Performance Plastics, and Feedstocks sales volume were mostly offset by a decrease in Basic Plastics sales volume. Offsetting these increases in net sales was a 2% decrease related to the prior year divestiture of our business in Brazil, as well as a 2% decrease due to an unfavorable currency impact across our segments, as the euro weakened in comparison to the U.S. dollar.

Cost of Sales

Of the 24% increase, 28% was attributable to higher prices for raw materials, primarily butadiene and styrene monomer. This increase was partially offset by a 2% decrease due to the prior year divestiture of our business in Brazil

27

as well as a 2% decrease due to a favorable currency impact across our segments, as the euro weakened in comparison to the U.S. dollar.

Gross Profit

The increase was primarily attributable to higher year-to-date margins, especially within the Latex Binders and Synthetic Rubber segments. Higher sales volume in Synthetic Rubber and Performance Plastics was partially offset by lower sales volume in Basic Plastics, as well as margin compression in Performance Plastics and lower styrene margins in Feedstocks, in addition to the styrene outage in Americas Styrenics. Also offsetting this net increase was an unfavorable currency impact as the euro weakened in comparison to the U.S. dollar.  

Selling, General and Administrative Expenses

Increased restructuring charges contributed to $2.2 million of this increase, primarily related to the Company’s decision to cease manufacturing activities at our latex facility in Livorno, Italy, as well as charges related to the upgrade and replacement of the Company’s compounding facility in Terneuzen, The Netherlands. Additionally, the increase includes costs from additional resources supporting growth initiatives as well as transaction and integration costs incurred in connection with Company’s acquisition of API Plastics, which closed in July 2017. Refer to Notes 13 and 16, respectively, 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 $70.6 million in 2016 to $48.4 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 $3.0 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 and therefore did not have an ownership interest in the joint venture for the majority of the six months ended June 30, 2017. Refer to Note 3 in the condensed consolidated financial statements for further information.

Interest Expense, Net

The decrease in interest expense was primarily attributable to lower deferred financing fee amortization recorded into interest expense from our Accounts Receivable Securitization Facility and lower interest expense incurred on the Company’s Euro Notes as a result of fluctuations in the euro foreign exchange rate.

Other Expense (Income), net

Other income, net for the six months ended June 30, 2017 was $6.1 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 $2.6 million, which included $7.9 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 $10.5 million of losses from our foreign exchange forward contracts.

Other expense, net for the six months ended June 30, 2016 was $15.5 million, which includes an impairment charge for the estimated loss on sale of our latex and automotive businesses in Brazil of approximately $12.9 million, as well as other expenses of $1.0 million. Refer to Note 11 in the condensed consolidated financial statements for further information. Adding to these losses were net foreign exchange transaction losses of $1.6 million. Included in these net losses of $1.6 million were foreign exchange transactions losses of $2.6 million, primarily due to by 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 $1.0 million from our foreign exchange forward contracts.

28

Provision for Income Taxes

Provision for income taxes for the six months ended June 30, 2017 totaled $48.1 million resulting in an effective tax rate of 21.3%. Provision for income taxes for the six months ended June 30, 2016 totaled $50.5 million resulting in an effective tax rate of 22.6%.

The decrease in provision for income taxes was primarily due to a lower amount of income before income taxes subject to tax.  Included in the $225.6 million income before income taxes for the six months ended June 30, 2017 is the $9.3 million gain on sale of our 50% share in Sumika Styron Polycarbonate, which was exempt from tax.  Conversely, included in the $223.1 million income before income taxes for the six months ended June 30, 2016 was an in impairment charge of $12.9 million for the estimated loss on sale of Trinseo Brazil, which did not provide a tax benefit to the Company.

2017 Outlook

We expect continued strong fundamental business performance over the remainder of 2017. However, due to recent sharp volatility in the prices of our key raw materials, we expect our results for the second half of 2017 to be impacted by unfavorable raw material timing, net of favorable price lag. We continue to make strong progress on the growth initiatives within our Performance Materials segments, including our recently completed acquisition of API Plastics, to go along with our other investments such as the SSBR expansion and pilot plant, new ABS capacity in China, and new product and application growth initiatives. Additionally, we expect to continue our strategy of balanced cash deployment and maximizing shareholder value, noting the recent approval from our board of directors of a 20% dividend increase as well as an increased repurchase authorization of 2 million shares.

Three Months Ended - June 30, 2017 vs. June 30, 2016

The decrease in Adjusted EBITDA was primarily due to lower margins on second quarter sales of styrene purchased during the first quarter maintenance-related outage at the St. James, LA, styrene facility in a decreasing price environment.

Six Months Ended - June 30, 2017 vs. June 30, 2016

The decrease in Adjusted EBITDA was primarily due to the planned first quarter styrene outage at its 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 through the second quarter of 2017.

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

34

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 six months ended June 30, 2017 and 2016, respectively:

	Three Months Ended				Six Months Ended
	June 30,				June 30,
(in millions)	2017		2016		2017		2016
Net income	$	60.2	$	95.8	$	177.5	$	172.6
Interest expense, net		18.7		18.8		36.9		37.7
Provision for income taxes		18.8		28.6		48.1		50.5
Depreciation and amortization		26.3		24.9		51.0		47.9
EBITDA(a)	$	124.0	$	168.1	$	313.5	$	308.7

Acquisition transaction and integration costs(d)		1.1		—		1.1		—
Other items(e)		—		0.3		—		2.2
Adjusted EBITDA	$	126.2	$	182.4	$	308.0	$	325.6

(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 six months ended June 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 three and six months ended June 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 $12.9 million. Refer to Note 11 in the condensed consolidated financial statements for further information.

(c) Restructuring and other charges for the three and six months ended June 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 contract termination charges related to the upgrade and replacement of the Company’s compounding facility in Terneuzen, The Netherlands. Refer to Note 13 in the condensed consolidated financial statements for further information. Restructuring and other charges for the three and six months ended June 30, 2016 primarily 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 six months ended June 30, 2017 relate to advisory and professional fees incurred in conjunction with the Company’s acquisition of API Plastics, which closed in July 2017. Refer to Note 16 in the condensed consolidated financial statements for further information.

The increases in accounts receivable and inventories were primarily due to increased raw material prices.

Net cash provided by operating activities during the six months ended June 30, 2016 totaled $179.7 million, due primarily to earnings for the period. Also impacting cash flows from operating activities for the period was $60.0 million in dividends from Americas Styrenics. Net cash used in operating assets and liabilities for the six months ended June 30, 2016 totaled $68.0 million, due primarily to increases in accounts receivable of $53.0 million and inventories of $16.7 million, respectively. The increase in accounts receivable was primarily due to higher net sales during the second 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.

Investing Activities

Net cash used in investing activities for the six months ended June 30, 2017 totaled $29.7 million, primarily from capital expenditures of $74.3 million during the period, partially offset by 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 six months ended June 30, 2016 totaled $48.2 million, primarily from capital expenditures of $53.2 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 six months ended June 30, 2017 totaled $79.8 million. This activity was primarily due to $56.4 million of payments related to the repurchase of ordinary shares during the period and $26.5

36

million of dividends paid, as well as $2.5 million of principal payments related to our 2021 Term Loan B. Partially offsetting these uses of cash was $6.0 million of proceeds received from the exercise of option awards.

Net cash used in financing activities during the six months ended June 30, 2016 totaled $97.0 million. This activity was primarily due to $94.4 million of payments related to the repurchase of ordinary shares during the period as well as $2.5 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.

Prior period information below has been recast from its previous presentation to reflect the Company’s current method for calculating Free Cash Flow. Prior to the third quarter of 2016, we calculated Free Cash Flow as cash from both operating and investing activities less the impact of changes in restricted cash. The Company believes our revised method is more aligned to investors’ common understanding of Free Cash Flow and allows for easier comparisons between the Company and its peers. Additionally, the Company has not reported material restricted cash balances since 2012 and is not expected to do so under its current practices.

	Six Months Ended

(in millions)	2017		2016
Cash provided by operating activities	$	36.6	$	179.7
Capital expenditures		(74.3)		(53.2)
Free Cash Flow	$	(37.7)	$	126.5

Refer to the discussion above for significant impacts to cash provided by operating activities for the six months ended June 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 June 30, 2017 and December 31, 2016, we had $1,218.0 million and $1,187.4 million, respectively, in outstanding indebtedness and $1,051.1 million and $890.7 million, respectively, in working capital. In addition, as of June 30, 2017 and December 31, 2016, we had $91.5 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.

Refer to our Annual Report for a detailed description of the Company’s debt structure, borrowing rates, and expected future payment obligations.

The following table outlines our outstanding indebtedness as of June 30, 2017 and December 31, 2016 and the associated interest expense, including amortization of deferred financing fees, and effective interest rates for such borrowings as of June 30, 2017 and December 31, 2016. Note that the effective interest rates below exclude the impact of deferred financing fee amortization.

*For the six months ended June 30, 2017, interest expense on “Other indebtedness” totaled less than $0.1 million.

Our Senior Credit Facility includes the 2020 Revolving Facility, which matures in May 2020, and has a borrowing capacity of $325.0 million. As of June 30, 2017, the Company had no outstanding borrowings, and had $308.1 million (net of $16.9 million outstanding letters of credit) of funds available for borrowing under the 2020 Revolving Facility.  Further, as of June 30, 2017, the Borrowers are required to pay a quarterly commitment fee in respect of any unused commitments under the 2020 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 June 30, 2017, there were no amounts outstanding under the Accounts Receivable Securitization Facility, with approximately $151.3 million of funds available for borrowing under this facility, based on the pool of eligible accounts receivable.

Our other borrowing arrangements include our $500.0 million 2021 Term Loan B (maturing in November 2021), which requires scheduled quarterly payments in amounts equal to 0.25% of the original principal, and our 2022 Senior Notes (maturing in May 2022), whose U.S. dollar equivalent outstanding amount as of June 30, 2017 totaled $727.3 million.

The Senior Credit Facility and Indenture contain certain customary affirmative, negative and financial covenants. As of June 30, 2017, the Company was in compliance with all of these debt covenant requirements. Refer to the Annual Report 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 2022 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

38

face transfer restrictions in the future due to regulatory or other reasons beyond our control.

The Company’s cash flow generation in recent years has been strong, with positive cash flows expected to continue for full year 2017. However, we can make no assurances that, in the future, our business will generate sufficient cash flow from operations or that future borrowings will be available to us under the Senior Credit Facility in an amount sufficient to enable us to pay our indebtedness, or to fund our other liquidity needs. In addition, our current indebtedness may limit our ability to procure additional financing in the future.

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. In April 2017, the Company paid a dividend of $0.30 per ordinary share (totaling $13.7 million), with an additional dividend to shareholders of $0.36 per ordinary share declared in June 2017 (to be paid in July 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.

We believe that funds provided by operations, our existing cash and cash equivalent balances, borrowings available under our 2020 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.

Contractual Obligations and Commercial Commitments

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.

Off-balance Sheet Arrangements

We do not have any off-balance sheet arrangements.

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 Qualitative 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

39

exposure to market risks from the information provided within our Annual Report, except to our risks related to changes in the prices of certain commodities that we use in the production of our products.

Commodity Price Risk

We purchase certain raw materials such as benzene, ethylene, butadiene, BPA and styrene primarily under short- and long-term supply contracts. The pricing terms for these raw material purchases are generally determined based on commodity indices and prevailing market conditions within the relevant geography. The selling prices of our products are generally based, in part, on the current or forecasted costs of our key raw materials, but are often subject to a predetermined lag period for the pass through of these costs.  As such, during periods of significant raw material price volatility, the Company may experience material volatility in earnings and cash flows due to the lag in passing through raw material costs, primarily benzene, ethylene, butadiene, and styrene. Assuming no changes in sales price, volume or mix, a hypothetical 10% change in the market price of our raw materials would have impacted cost of sales by $155 million for the six months ended June 30, 2017.

We mitigate the risk of volatility in commodity prices where possible by passing changes in raw material costs through to our customers by adjusting our prices or including provisions in our contracts that allow us to adjust prices in such a circumstance or by including pricing formulas which utilize commodity indices. Nevertheless, we may be subject to the timing differences described above for the pass through of these costs. In addition, even when raw material costs may be passed on to our customers, during periods of high raw material price volatility, customers without minimum purchase requirements with us may choose to delay purchases of our materials or, in some cases, substitute purchases of our materials with less costly products. 

We do not enter into derivative financial instruments for trading or speculative purposes to manage our commodity price risk relating to our raw material contracts.

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 June 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

There was no change 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 June 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 Proceedings  

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.

40

Item 1A. Risk Factors 

Our business faces various risks. Certain important factors may have a material adverse effect on our business prospects, financial condition and results of operations, and you should carefully consider them. Accordingly, in evaluating our business, we encourage you to consider the risk factors related to our ordinary shares as well those risk factors related to our business and industry which have been previously disclosed in Item 1A of our Annual Report for the year ended December 31, 2016, for which there have been no material changes. We encourage you to consider these risks, in their entirety, in addition to other information contained in or incorporated by reference into this Quarterly Report and our other public filings with the SEC. Other events that we do not currently anticipate or that we currently deem immaterial may also affect our business, prospects, financial condition and results of operations.

Exhibit 3.1

AMENDED AND RESTATED ARTICLES OF ASSOCIATION OF

TRINSEO S.A.

I. name – registered office – object – duration

1            Name

The name of the company is “Trinseo S.A.” (the Company). The Company is a public limited liability company (société anonyme) governed by the laws of the Grand Duchy of Luxembourg, in particular the law of August 10, 1915, on commercial companies, as amended from time to time (the CompanyLaw), and these articles of association (the Articles).

2            Registered office

2.1         The Company’s registered office is established in Luxembourg, Grand Duchy of Luxembourg. It may be transferred to any other location in the Grand Duchy of Luxembourg by a resolution of the board of directors of the Company (the Board), and the Board may amend the Articles to reflect this change.

2.2         Branches, subsidiaries or other offices may be established in the Grand Duchy of Luxembourg or abroad by a resolution of the Board. If the Board determines that extraordinary political or military developments or events have occurred or are imminent, and that those developments or events may interfere with the normal activities of the Company at its registered office or the communication between that office and persons abroad, the registered office may be temporarily transferred abroad until such developments or events have completely ceased. Any such temporary measures do not affect the nationality of the Company, which, notwithstanding the temporary transfer of its registered office, will remain a Luxembourg incorporated company.

3            Corporate object

3.1         The Company’s object is the acquisition of participations, in Luxembourg or abroad, in any company or enterprise in any form whatsoever, and the management, development and sale of those participations. The Company may in particular acquire and sell, by subscription, purchase and exchange or in any other manner, any stock, shares and other participation securities, bonds, debentures, certificates of deposit and other debt instruments and, more generally, any securities and financial instruments issued by any public or private entity. It may participate in the creation, development, management and control of any company or enterprise. Further, it may invest in the acquisition and management of a portfolio of patents or other intellectual property rights of any nature or origin.

3.2         The Company may borrow in any form. The Company may issue notes, bonds and any kind of debt and equity securities. It may issue convertible funding instruments and warrants. The Company may lend funds, including, without limitation, the proceeds of any borrowings to its subsidiaries and affiliated companies. It may also give guarantees and pledge, transfer,

encumber or otherwise create and grant security over some or all of its assets to guarantee its own obligations and those of any other company, subsidiary or affiliate, and, generally, for its own benefit and that of any other company or person. The Company may issue warrants or any other instrument which allows the holder of such instrument to subscribe for shares in the Company. For the avoidance of doubt, the Company may not carry out any regulated financial sector activities without having obtained the requisite authorisation.

3.3         The Company may use any techniques, legal means and instruments to manage its investments efficiently and protect itself against credit risks, currency exchange exposure, interest rate risks and other risks.

3.4         The Company may carry out any commercial, financial or industrial operation and any transaction with respect to real estate or movable property, which directly or indirectly, favours or relates to its corporate object (including without limitation the performance of any kind of services to its subsidiaries).

4            Duration

4.1         The Company is formed for an unlimited period.

4.2         The Company shall not be dissolved by reason of the death, suspension of civil rights, incapacity, insolvency, bankruptcy or any similar event affecting one (1) or more shareholders of the Company (each a Shareholder, and, together, the Shareholders).

II. capital - shares

5            Issued share capital

5.1         The issued share capital is set at four hundred eighty-seven thousand seven hundred seventy-nine United States Dollars and thirty-four United States Dollar cents (USD 487,779.34), represented by forty-eight million seven hundred seventy seven thousand nine hundred thirty four (48,777,934) ordinary shares with nominal value of one United States Dollar cent (USD 0.01) each, all subscribed and fully paid-up (the Shares). 

5.2         The authorised share capital is set at five hundred million United States Dollars (USD 500,000,000) represented by fifty billion (50,000,000,000) shares.

5.3         The issued share capital and the authorised share capital may be increased or decreased once or several times by a resolution of the General Meeting, acting in accordance with the conditions prescribed for the amendment of these Articles.

5.4         Subject to the provisions of the Company Law and these Articles, each Shareholder has a preferential subscription right in the event of the issuance of new Shares by the Company in return for contributions in cash. Such preferential subscription right shall be proportional to the fraction of the capital represented by the Shares held by each Shareholder immediately prior to such issuance.

5.5         The Board is authorised, for a period of five (5) years from the date of publication of these Articles, and without prejudice to any renewals, to:

(a)     increase the issued share capital, in whole or in part and on one (1) or more occasions, up to the authorised share capital by the issuance of Shares up to the limits for each class, with the rights as set out in these Articles, against payment in cash or in kind or against a contribution of share premium, account 115, distributable reserves or retained earnings;

(b)     determine the place and date of the issue (or any successive issue) and the terms and conditions of the subscription for the Shares;

(c)     determine the allocation of the subscription price for the Shares to the share capital, share premium and/or any other reserve account of the Company;

(d)     limit and/or withdraw the preferential subscription rights of existing Shareholders in case of an issuance of Shares, as the case may be; and

(e)     record each such share capital increase by way of a notarial deed and amend the register of Shares to reflect the amendment accordingly.

5.6         The Shareholders’ preferential subscription rights to any Shares may also be limited or cancelled by a resolution of the General Meeting adopted with the same majority and quorum as set out in Section 9.4.3 of these Articles.

5.7         Whenever the General Meeting or Board has effected a share capital increase pursuant to the foregoing provisions, Section 5.1 of these Articles shall be amended so as to reflect the increase.

5.8         The Board is authorised to carry out (i) a free allocation of new Shares (within the limits of the Company’s authorised share capital as detailed at Articles 5.2 and 5.5 above) and (ii) to allocate existing Shares for no consideration, in each case to those persons to whom such free allocation or issuance is permitted in the Company Law.  The Board is further authorised to set the terms and conditions of such allocation or issuance.

6            Shares

6.1         Each Share is indivisible. In case of the holding of a Share by more than one person, the Company has the right to suspend the exercise of all rights attaching to such jointly held Share (except the information rights provided by Article 73 of the Company Law) until a sole person has been designated as the holder of such Share of the Company.

6.2         All Shares shall be identical in all respects and shall share rateably in the payment of dividends and in any distribution of assets which are allocated to such Shares in accordance with the payment allocation set out in Section 12 of these Articles.

6.3         A register of shares (the Register) shall be kept at the registered office and may be examined by any Shareholder during normal business hours subject to reasonable notice and the provisions of Article 39 of the Company Law.

6.4         Subject to Section 6.5, the Company shall consider the person in whose name Shares are recorded in the Register to be the owner of those Shares.

6.5         Where Shares are recorded in the Register on behalf of one (1) or more persons (each a Beneficiary) in the name of a securities settlement system or the operator of such a system or in the name of a professional depositary of securities or any other depositary or of a sub-depositary designated by one (1) or more of such depositaries (each such systems, professionals or other depositaries or sub-depositories, a Depositary), the Company shall:

(a)     permit the Beneficiary to exercise the rights attaching to those Shares, including admission to and voting at General Meetings; and

WHEREAS, pursuant to Section 9.1 of the Indenture, the Issuers hereby request that the Trustee join with the Issuers, the Guarantors and the Guaranteeing Subsidiary in the execution of this Supplemental Indenture.

NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Guaranteeing Subsidiary, the Issuers, the other Guarantors and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders of the Notes as follows:

ARTICLE I

DEFINITIONS

SECTION 1.1.Defined Terms.  As used in this Supplemental Indenture, terms defined in the Indenture or in the preamble or recitals hereto are used herein as therein defined.  The words “herein,”

“hereof” and “hereby” and other words of similar import used in this Supplemental Indenture refer to this Supplemental Indenture as a whole and not to any particular section hereof.

ARTICLE II

AGREEMENT TO BE BOUND; GUARANTEE

SECTION 2.1.Agreement to Be Bound.  The Guaranteeing Subsidiary hereby becomes a party to the Indenture as a Guarantor and as such will have all of the rights and be subject to all of the obligations and agreements of a Guarantor under the Indenture.

SECTION 2.2.Guarantee.  The Guaranteeing Subsidiary agrees, on a joint and several basis with all the existing Guarantors, to fully, unconditionally and irrevocably Guarantee to each Holder of the Notes and the Trustee the Guaranteed Obligations pursuant to Article X of the Indenture on a senior basis. 

(a) The aggregate liability of the Guaranteeing Subsidiary for Restricted Obligations (as defined in Schedule I to the Indenture) shall be limited to the amount available for distribution as dividends to the shareholders of the Guaranteeing Subsidiary at the time the Guaranteeing Subsidiary is required to perform under any Transaction Document, provided that this is a requirement under applicable Swiss law at that time and further provided that such limitation shall not discharge the Guaranteeing Subsidiary from its obligations in excess thereof, but merely postpone the performance date thereof until such times as performance is again permitted notwithstanding such limitation. Any and all indemnities and guarantees contained in the Transaction Documents shall be construed in a manner consistent with the provisions herein contained.

(b) In respect of Restricted Obligations, the Guaranteeing Subsidiary shall:

(1) if and to the extent required by applicable law in force at the relevant time use its best efforts to mitigate to the extent possible any obligation with respect to withholding tax in accordance with the Federal Act on Anticipatory Tax of 13 October 1965, as amended (Bundesgesetz über die Verrechnungssteuer) ("Swiss Withholding Tax") to be levied on the Restricted Obligations (and cause its parent and other relevant Affiliates to fully cooperate in any mitigating efforts), in particular through the notification procedure, and promptly notify the Trustee thereof or, if such a notification procedure is not applicable:

(A) deduct Swiss Withholding Tax at the rate of 35 per cent. (or such other rate as in force from time to time pursuant to, in particular, any applicable double taxation treaty) from any payment made by it in respect of Restricted Obligations; 

(B) pay any such deduction to the Swiss Federal Tax Administration; and

(C) notify (and the Issuers shall ensure that the Guaranteeing Subsidiary will notify) the Trustee that such a deduction has been made and provide the Trustee with evidence that such a deduction has been paid to the Swiss Federal Tax Administration; and

(2) to the extent such a deduction is made, not be obliged to pay Additional Amounts in relation to any such payment made by it in respect of Restricted Obligations unless such payment is permitted under the laws of Switzerland then in force (it being understood that this shall not in any way limit

any obligations of any other Guarantor or the Issuers under any Transaction Document to indemnify the Holders of the Notes and the Trustee in respect of the deduction of the Swiss Withholding Tax). The Guaranteeing Subsidiary shall use its commercially reasonable efforts to ensure that any Person which is, as a result of a deduction of Swiss Withholding Tax, entitled to a full or partial refund of the Swiss Withholding Tax, will, as soon as possible after the deduction of the Swiss Withholding Tax, (i) request a refund of the Swiss Withholding Tax under any applicable law (including double tax treaties) and (ii) promptly upon receipt, pay to the Trustee (or to any such other Person as directed by the Trustee) any amount so refunded for application as a further payment of the Guaranteeing Subsidiary under and pursuant to the relevant Transaction Document.

(c) If and to the extent requested by the Trustee and if and to the extent this is from time to time required under Swiss law (restricting profit distributions), in order to allow the Holders of the Notes and the Trustee to obtain a maximum benefit under Article X of the Indenture, the Guaranteeing Subsidiary shall, and any parent company of the Guaranteeing Subsidiary being a party to the Indenture shall procure that the Guaranteeing Subsidiary will, promptly implement all such measures and/or promptly procure the fulfillment of all prerequisites allowing it to promptly make the (requested) payment(s) hereunder from time to time, including the following:

(1) preparation of an up-to-date audited balance sheet of the Guaranteeing Subsidiary;

(2) confirmation of the auditors of the Guaranteeing Subsidiary that the relevant amount represents (the maximum of) freely distributable profits;

(3) conversion of restricted reserves into profits and reserves freely available for the distribution as dividends (to the extent permitted by mandatory Swiss law);

(4) revaluation of hidden reserves (to the extent permitted by mandatory Swiss law);

(5) approval by a shareholders’ meeting of the Guaranteeing Subsidiary of the (resulting) profit distribution; and

(6) all such other measures necessary or useful to allow the Guaranteeing Subsidiary to make the payments agreed hereunder with a minimum of limitations.

ARTICLE III

Exhibit 10.1

FORM OF INDEMNIFICATION AGREEMENT

This Indemnification Agreement (“Agreement”) is effective as of [DATE] by and between Trinseo S.A., a public limited liability company (société anonyme) existing under the laws of the Grand Duchy of Luxembourg (the “Company”), and <NAME> (“Indemnitee”).  [The prior indemnification agreement between the Company and Indemnitee shall be deemed superseded by this Agreement as of the effective date of this Agreement.]

WHEREAS, in light of the litigation costs and risks to directors and executive officers resulting from their service to the Company, and the desire of the Company to attract and retain qualified individuals to serve as directors and executive officers, it is reasonable, prudent and necessary for the Company to indemnify and advance expenses on behalf of its directors and executive officers to the extent permitted by applicable law so that they will serve or continue to serve the Company free from undue concern regarding such risks;

WHEREAS, the Company has requested that Indemnitee serve or continue to serve as a director and/or executive officer of the Company and may have requested or may in the future request that Indemnitee serve one or more Entities (as hereinafter defined) as a director, executive officer or in other capacities; and

WHEREAS, Indemnitee may have certain rights to indemnification, advancement of expenses and/or insurance provided by the Company (or its subsidiaries); and with the Company’s acknowledgement of and agreement to the foregoing being a material condition to Indemnitee’s willingness to serve as a director and/or executive officer of the Company.

NOW, THEREFORE, in consideration of the premises and the covenants contained herein, the Company and Indemnitee do hereby covenant and agree as follows:

1.         Services by Indemnitee.  Indemnitee agrees to serve as a director and/or executive officer of the Company.  Indemnitee may at any time and for any reason resign from such position (subject to any contractual obligation under any other agreement or any obligation imposed by operation of law).

2.         Indemnification - General.  On the terms and subject to the conditions of this Agreement, the Company shall, to the fullest extent permitted by law, indemnify Indemnitee with respect to, and hold Indemnitee harmless from and against, all losses, liabilities, judgments, fines, penalties, costs, amounts paid in settlement, Expenses (as hereinafter defined) and other amounts that Indemnitee incurs and that result from, arise in connection with or are by reason of Indemnitee’s Corporate Status (as hereinafter defined) and shall advance Expenses to Indemnitee.  The obligations of the Company under this Agreement (a) are joint and several obligations of the Company and its subsidiaries, (b) shall continue after such time as Indemnitee ceases to serve as a director or an officer of the Company or in any other Corporate Status, and (c) include, without limitation, claims for monetary damages against Indemnitee in respect of any actual or alleged liability or other loss of Indemnitee, to the fullest extent permitted under applicable law as in existence on the date hereof and as amended from time to time.

-  1  -

3.         Proceedings Other Than Proceedings by or in the Right of the Company.  If in connection with or by reason of Indemnitee’s Corporate Status, Indemnitee was, is, or is threatened to be made, a party to or a participant in any Proceeding (as hereinafter defined) other than a Proceeding by or in the right of the Company to procure a judgment in its favor, the Company shall, to the fullest extent permitted by law, indemnify Indemnitee with respect to, and hold Indemnitee harmless from and against, all Expenses, liabilities, judgments, penalties, fines and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of such liabilities, judgments, penalties, fines and amounts paid in settlement) incurred by Indemnitee or on behalf of Indemnitee in connection with such Proceeding or any claim, issue or matter therein.

4.         Proceedings by or in the Right of the Company.  If in connection with or by reason of Indemnitee’s Corporate Status, Indemnitee was, is, or is threatened to be made, a party to or a participant in any Proceeding by or in the right of the Company to procure a judgment in the Company’s favor, the Company shall, to the fullest extent permitted by law, indemnify Indemnitee with respect to, and hold Indemnitee harmless from and against, all Expenses incurred by Indemnitee or on behalf of Indemnitee in connection with such Proceeding or any claim, issue or matter therein.

5.         Mandatory Indemnification in Case of Successful Defense.  Notwithstanding any other provision of this Agreement, to the extent that Indemnitee is a party to (or a participant in) and is successful, on the merits or otherwise, in defense of any Proceeding or any claim, issue or matter therein (including, without limitation, any Proceeding brought by or in the right of the Company), the Company shall, to the fullest extent permitted by law, indemnify Indemnitee with respect to, and hold Indemnitee harmless from and against, all Expenses incurred by Indemnitee or on behalf of Indemnitee in connection therewith.  If Indemnitee is not wholly successful in defense of such Proceeding but is successful, on the merits or otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall, to the fullest extent permitted by law, indemnify Indemnitee against all Expenses incurred by Indemnitee or on behalf of Indemnitee in connection with each successfully resolved claim, issue or matter.  For purposes of this Section 5 and without limitation, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice, on substantive or procedural grounds, or settlement of any such claim prior to a final judgment by a court of competent jurisdiction with respect to such Proceeding, shall be deemed to be a successful result as to such claim, issue or matter.    

6.         Partial Indemnification.  If Indemnitee is entitled under any provision of this Agreement or otherwise to indemnification by the Company for some or a portion of the Expenses, liabilities, judgments, penalties, fines and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of such liabilities, judgments, penalties, fines and amounts paid in settlement) incurred by Indemnitee or on behalf of Indemnitee in connection with a Proceeding or any claim, issue or matter therein, in whole or in part, the Company shall, to the fullest extent permitted by law, indemnify Indemnitee to the fullest extent to which Indemnitee is entitled to such indemnification.

-  2  -

7.         Indemnification for Additional Expenses Incurred to Secure Recovery or as Witness.

(a)        The Company shall, to the fullest extent permitted by law, indemnify Indemnitee with respect to, and hold Indemnitee harmless from and against, any and all Expenses and, if requested by Indemnitee, shall advance on an as-incurred basis (as provided in Section 8 of this Agreement) such Expenses to Indemnitee, which are incurred by Indemnitee in connection with any action or proceeding or part thereof brought by Indemnitee for (i) indemnification or advance payment of Expenses by the Company under this Agreement, any other agreement, the Articles of Association as now or hereafter in effect, (ii) recovery under any director and officer liability insurance policies maintained by the Company or any of its subsidiaries.

(b)        To the extent that Indemnitee is a witness (or is forced or asked to respond to discovery requests) in any Proceeding to which Indemnitee is not a party, the Company shall, to the fullest extent permitted by law, indemnify Indemnitee with respect to, and hold Indemnitee harmless from and against, and the Company will advance on an as-incurred basis (as provided in Section 8 of this Agreement), all Expenses incurred by Indemnitee or on behalf of Indemnitee in connection therewith.

8.         Advancement of Expenses.  The Company shall, to the fullest extent permitted by law, pay on a current and as-incurred basis all Expenses incurred by Indemnitee in connection with any Proceeding in any way connected with, resulting from or relating to Indemnitee’s Corporate Status.  Such Expenses shall be paid in advance of the final disposition of such Proceeding, without regard to whether Indemnitee will ultimately be entitled to be indemnified for such Expenses and without regard to whether an Adverse Determination (as hereinafter defined) has been or may be made, except as contemplated by the last sentence of Section 9(f) of this Agreement.  Upon submission of a request for advancement of Expenses pursuant to Section 9(c) of this Agreement, Indemnitee shall be entitled to advancement of Expenses as provided in this Section 8, and such advancement of Expenses shall continue until such time (if any) as there is a final non-appealable judicial determination that Indemnitee is not entitled to indemnification.  Indemnitee shall repay such amounts advanced if and to the extent that it shall ultimately be determined in a decision by a court of competent jurisdiction from which no appeal can be taken that Indemnitee is not entitled to be indemnified by the Company for such Expenses.  Such repayment obligation shall be unsecured and shall not bear interest.  The Company shall not impose on Indemnitee additional conditions to advancement or require from Indemnitee additional undertakings regarding repayment.

9.         Indemnification Procedures.

(a)        Notice of Proceeding.  Indemnitee agrees to notify the Company promptly upon being served with any summons, citation, subpoena, complaint, indictment, information or other document relating to any Proceeding or matter which may be subject to indemnification or advancement of Expenses hereunder.  Any failure by Indemnitee to notify Company will relieve the Company of its advancement or indemnification obligations under this Agreement only to the extent the Company can establish that such omission to notify resulted in actual and material prejudice to it which cannot be reversed or otherwise eliminated without any material negative

-  3  -

effect on the Company, and the omission to notify the Company will, in any event, not relieve the Company from any liability which it may have to indemnify Indemnitee otherwise than under this Agreement.  If, at the time of receipt of any such notice, the Company has director and officer insurance policies in effect, the Company will promptly notify the relevant insurers in accordance with the procedures and requirements of such policies.

(b)        Defense; Settlement.  Indemnitee shall have the sole right and obligation to control the defense or conduct of any claim or Proceeding with respect to Indemnitee.  The Company shall not, without the prior written consent of Indemnitee, which may be provided or withheld in Indemnitee’s sole discretion, effect any settlement of any Proceeding against Indemnitee or which could have been brought against Indemnitee or which potentially or actually imposes any cost, liability, exposure or burden on Indemnitee unless (i) such settlement solely involves the payment of money or performance of any obligation by persons other than Indemnitee and includes an unconditional release of Indemnitee by all relevant parties from all liability on any matters that are the subject of such Proceeding and an acknowledgment that Indemnitee denies all wrongdoing in connection with such matters and (ii) the Company has  fully indemnified the Indemnitee with respect to, and held Indemnitee harmless from and against, all Expenses incurred by Indemnitee or on behalf of Indemnitee in connection with such Proceeding.  The Company shall not be obligated to indemnify Indemnitee against amounts paid in settlement of a Proceeding against Indemnitee if such settlement is effected by Indemnitee without the Company’s prior written consent, which consent shall not be unreasonably withheld, delayed or conditioned, unless such settlement solely involves the payment of money or performance of any obligation by persons other than the Company and includes an unconditional release of the Company by any party to such Proceeding other than the Indemnitee from all liability on any matters that are the subject of such Proceeding and an acknowledgment that the Company deny all wrongdoing in connection with such matters.

(c)        Request for Advancement; Request for Indemnification. 

(i)        To obtain advancement of Expenses under this Agreement, Indemnitee shall submit to the Company a written request therefor, together with such invoices or other supporting information as may be reasonably requested by the Company and reasonably available to Indemnitee, and, only to the extent required by applicable law which cannot be waived, an unsecured written undertaking to repay amounts advanced.  The Company shall make advance payment of Expenses to Indemnitee no later than five (5) business days after receipt of the written request for advancement (and each subsequent request for advancement) by Indemnitee.    If, at the time of receipt of any such written request for advancement of Expenses, the Company has director and officer insurance policies in effect, the Company will promptly notify the relevant insurers in accordance with the procedures and requirements of such policies.  The Company shall thereafter keep such director and officer insurers informed of the status of the Proceeding or other claim and take such other actions, as appropriate to secure coverage of Indemnitee for such claim.

(ii)       To obtain indemnification under this Agreement, Indemnitee may submit a written request for indemnification hereunder.  The time at which Indemnitee submits a written request for indemnification shall be determined by the Indemnitee in the Indemnitee's

-  4  -

sole discretion.  Once Indemnitee submits such a written request for indemnification (and only at such time that Indemnitee submits such a written request for indemnification), a Determination (as hereinafter defined) shall thereafter be made, as provided in and only to the extent required by Section 9(d) of this Agreement.  In no event shall a Determination be made, or required to be made, as a condition to or otherwise in connection with any advancement of Expenses pursuant to Section 8 and Section 9(c)(i) of this Agreement.  If, at the time of receipt of any such request for indemnification, the Company has director and officer insurance policies in effect, the Company will promptly notify the relevant insurers and take such other actions as necessary or appropriate to secure coverage of Indemnitee for such claim in accordance with the procedures and requirements of such policies.

(d)        Determination.  The Company agrees that Indemnitee shall be indemnified to the fullest extent permitted by law and that no Determination shall be required in connection with such indemnification unless specifically required by applicable law which cannot be waived.  In no event shall a Determination be required in connection with indemnification for Expenses pursuant to Section 7 of this Agreement or incurred in connection with any Proceeding or portion thereof with respect to which Indemnitee has been successful on the merits or otherwise.  Any decision that a Determination is required by law in connection with any other indemnification of Indemnitee, and any such Determination, shall be made within twenty (20) days after receipt of Indemnitee’s written request for indemnification pursuant to Section 9(c)(ii) and such Determination shall be made either (i) by the Disinterested Directors (as hereinafter defined), even though less than a quorum, so long as Indemnitee does not request that such Determination be made by Independent Counsel (as hereinafter defined), or (ii) if so requested by Indemnitee, in Indemnitee’s sole discretion, by Independent Counsel in a written opinion to the Company and Indemnitee.  If a Determination is made that Indemnitee is entitled to indemnification, payment to Indemnitee shall be made within five (5) business days after such Determination.  Indemnitee shall reasonably cooperate with the person, persons or entity making such determination with respect to Indemnitee’s entitlement to indemnification, including providing to such person, persons or entity upon reasonable advance request any documentation or information which is not privileged or otherwise protected from disclosure and which is reasonably available to Indemnitee and reasonably necessary to such Determination.  Any Expenses incurred by Indemnitee in so cooperating with the Disinterested Directors or Independent Counsel, as the case may be, making such determination shall be advanced and borne by the Company (irrespective of the Determination as to Indemnitee’s entitlement to indemnification) and the Company is liable to indemnify and hold Indemnitee harmless therefrom.  If the person, persons or entity empowered or selected under Section 9(d) of this Agreement to determine whether Indemnitee is entitled to indemnification shall not have made a determination within twenty (20) days after receipt by the Company of the request therefor, the requisite determination of entitlement to indemnification shall, to the fullest extent not prohibited by law, be deemed to have been made and Indemnitee shall be entitled to such indemnification, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law; provided, however, that such twenty (20) day period may be extended for a reasonable time, not to exceed an additional twenty (20) days, if the person, persons or entity making the

-  5  -

determination with respect to entitlement to indemnification in good faith requires such additional time for the obtaining or evaluating of documentation and/or information relating thereto; and provided, further, that the foregoing provisions of this Section 9(d) shall not apply if the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 9(e).

(e)        Independent Counsel.  In the event Indemnitee requests that the Determination be made by Independent Counsel pursuant to Section 9(d) of this Agreement, the Independent Counsel shall be selected as provided in this Section 9(e).  The Independent Counsel shall be selected by Indemnitee (unless Indemnitee shall request that such selection be made by the Board of Directors, in which event the Board of Directors shall make such selection on behalf of the Company, subject to the remaining provisions of this Section 9(e)), and Indemnitee or the Company, as the case may be, shall give written notice to the other, advising the Company or Indemnitee of the identity of the Independent Counsel so selected.  The Company or Indemnitee, as the case may be, may, within five (5) days after such written notice of selection shall have been received, deliver to Indemnitee or the Company, as the case may be, a written objection to such selection; provided,  however, that such objection may be asserted only on the ground that the Independent Counsel so selected does not meet the requirements of “Independent Counsel” as defined in Section 15 of this Agreement, and the objection shall set forth with particularity the factual basis of such assertion.  Absent a proper and timely objection, the person so selected shall act as Independent Counsel.  If a written objection is so made and substantiated, the Independent Counsel so selected may not serve as Independent Counsel unless and until such objection is withdrawn or a court of competent jurisdiction has determined that such objection is without merit.  If, within ten (10) days after submission by Indemnitee of a written request for indemnification pursuant to Section 9(c)(ii) of this Agreement and after a request for the appointment of Independent Counsel has been made, no Independent Counsel shall have been selected and not objected to, either the Company or Indemnitee may petition a court of competent jurisdiction for resolution of any objection which shall have been made by the Company or Indemnitee to the other’s selection of Independent Counsel and/or for the appointment as Independent Counsel of a person selected by the court or by such other person as the court shall designate, and the person with respect to whom all objections are so resolved or the person so appointed shall act as Independent Counsel under Section 9(d) of this Agreement.  Upon the due commencement of any judicial proceeding or arbitration pursuant to Section 9(f) of this Agreement, Independent Counsel shall be discharged and relieved of any further responsibility in such capacity (subject to the applicable standards of professional conduct then prevailing).  Any expenses incurred by or in connection with the appointment of Independent Counsel shall be borne by the Company (irrespective of the Determination of Indemnitee's entitlement to indemnification) and not by Indemnitee.

(f)        Consequences of Determination; Remedies of Indemnitee.  The Company shall be bound by and shall have no right to challenge a Favorable Determination.  If an Adverse Determination is made, or if for any other reason the Company do not make timely indemnification payments or advances of Expenses, Indemnitee shall have the right to commence a Proceeding before a court of competent jurisdiction to challenge such Adverse Determination and/or to require the Company to make such payments or advances (and the Company shall have the right to defend its position in such Proceeding and to appeal any adverse

-  6  -

judgment in such Proceeding).  Indemnitee shall be entitled to be indemnified for all Expenses incurred in connection with such a Proceeding and to have such Expenses advanced by the Company in accordance with Section 8 of this Agreement.  If Indemnitee fails to challenge an Adverse Determination within thirty (30) business days, or if Indemnitee challenges an Adverse Determination and such Adverse Determination has been upheld by a final judgment of a court of competent jurisdiction from which no appeal can be taken, then, to the extent and only to the extent required by such Adverse Determination or final judgment, the Company shall not be obligated to indemnify or advance Expenses to Indemnitee under this Agreement.

(g)        Presumptions; Burden and Standard of Proof.    The parties intend and agree that, to the extent permitted by law, in connection with any Determination with respect to Indemnitee’s entitlement to indemnification hereunder by any person, including a court:

(i)        it will be presumed that Indemnitee is entitled to indemnification under this Agreement (notwithstanding any Adverse Determination), and the Company or any other person or entity challenging such right will have the burden of proof to overcome that presumption in connection with the making by any person, persons or entity of any determination contrary to that presumption;

(ii)       the termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that Indemnitee did not act in good faith and in a manner which Indemnitee reasonably believed to be in or not opposed to the best interests of the Company, and, with respect to any criminal action or proceeding, had reasonable cause to believe that Indemnitee’s conduct was unlawful;

(iii)      Indemnitee will be deemed to have acted in good faith if Indemnitee’s action is based on the records or books of account of the Company, including financial statements, or on information supplied to Indemnitee by the officers, employees, or committees of the board of directors of the Company, or on the advice of legal counsel or other advisors (including financial advisors and accountants) for the Company or on information or records given in reports made to the Company by an independent certified public accountant or by an appraiser or other expert or advisor selected by the Company; and

(iv)      the knowledge and/or actions, or failure to act, of any director, officer, agent or employee of the Company or relevant enterprises will not be imputed to Indemnitee in a manner that limits or otherwise adversely affects Indemnitee’s rights hereunder.

The provisions of this Section 9(g) shall not be deemed to be exclusive or to limit in any way the other circumstances in which Indemnitee may be deemed to have met the applicable standard of conduct set forth in this Agreement. 

10.       Remedies of Indemnitee.

(a)        Subject to Section 10(e), in the event that (i) a determination is made pursuant to Section 9(d) of this Agreement that Indemnitee is not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 9(c)

-  7  -

of this Agreement, (iii) no determination of entitlement to indemnification shall have been made pursuant to Section 9(d) of this Agreement within twenty (20) days after receipt by the Company of the request for indemnification, (iv) payment of indemnification is not made pursuant to Section 5,  6 or 7 of this Agreement within five (5) business days after receipt by the Company of a written request therefor, (v) payment of indemnification pursuant to Section 3,  4 or 7 of this Agreement is not made within five (5) business days after a determination has been made that Indemnitee is entitled to indemnification, or (vi) in the event that the Company or any other person takes or threatens to take any action to declare this Agreement void or unenforceable, or institutes any litigation or other action or Proceeding designed to deny, or to recover from, the Indemnitee the benefits provided or intended to be provided to the Indemnitee hereunder, Indemnitee shall be entitled to an adjudication by a court of his entitlement to such indemnification or advancement of Expenses.  Alternatively, Indemnitee, at his option, may seek an award in arbitration to be conducted by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association.  The Company shall not oppose Indemnitee’s right to seek any such adjudication or award in arbitration.

(b)        In the event that a determination shall have been made pursuant to Section 9(d) of this Agreement that Indemnitee is not entitled to indemnification, any judicial proceeding or arbitration commenced pursuant to this Section 10 shall be conducted in all respects as a denovo trial, or arbitration, on the merits, in which (i) Indemnitee shall not be prejudiced by reason of that adverse determination, and (ii) the Company shall bear the burden of establishing that Indemnitee is not entitled to indemnification. 

(c)        If a determination shall have been made pursuant to Section 9(d) of this Agreement that Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any judicial proceeding or arbitration commenced pursuant to this Section 10, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law.

(d)        Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement of Indemnitee to indemnification under this Agreement shall be required to be made prior to the final disposition of the Proceeding.

11.         Insurance; Subrogation; Other Rights of Recovery, etc.

(a)         The Company shall use its reasonable best efforts to purchase and maintain a policy or policies of insurance with reputable insurance companies with A.M. Best ratings of “A” or better, providing Indemnitee with coverage for any liability asserted against, and incurred by, Indemnitee or on Indemnitee’s behalf by reason of Indemnitee’s Corporate Status, or arising out of Indemnitee’s status as such, whether or not the Company would have the power to indemnify Indemnitee against such liability.  Such insurance policies shall have coverage terms and policy limits at least as favorable to Indemnitee as the insurance coverage provided to any other director or officer of the Company.  If the Company has such insurance in effect at the time it receives from Indemnitee any notice of the commencement of an action, suit, proceeding or other claim, the Company shall give prompt notice of the commencement of such action, suit,

-  8  -

proceeding or other claim to the insurers and take such other actions in accordance with the procedures set forth in the policy as required or appropriate to secure coverage of Indemnitee for such action, suit, proceeding or other claim.  The Company shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of Indemnitee, all amounts payable as a result of such action, suit, proceeding or other claim in accordance with the terms of such policy.  The Company shall continue to provide such insurance coverage to Indemnitee for a period of at least ten (10) years after Indemnitee ceases to serve as a director or an officer or in any other Corporate Status.

(b)        In the event of any payment by the Company under this Agreement, Indemnitee hereby agrees, as a condition to obtaining any advancement or indemnification from the Company, to assign to the Company all of Indemnitee’s rights to obtain from such other entity such amounts to the extent that they have been paid by the Company to or for the benefit of Indemnitee as advancement or indemnification under this Agreement and are adequate to indemnify Indemnitee with respect to the costs, Expenses or other items to the full extent that Indemnitee is entitled to indemnification or other payment hereunder; and Indemnitee will (upon request by the Company) execute all papers required and use reasonable best efforts to take all action reasonably necessary to secure such rights, including execution of such documents as are necessary to enable the Company to bring suit or enforce such rights.

(c)        The Company hereby unconditionally and irrevocably waives, relinquishes and releases, and covenants and agrees not to exercise (and to cause each of its subsidiaries not to exercise), any rights that the Company may now have or hereafter acquire against the Indemnitee that arise from or relate to the existence, payment, performance or enforcement of the Company’s obligations under this Agreement or under any other indemnification agreement with any person or entity, including, without limitation, any right of subrogation (whether pursuant to contract or common law), reimbursement, exoneration, contribution or indemnification, or to be held harmless, whether or not such claim, remedy or right arises in equity or under contract, statute or common law, including, without limitation, the right to take or receive from the Indemnitee, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim, remedy or right.

(d)        The Company shall not be liable to pay or advance to Indemnitee any amounts otherwise indemnifiable under this Agreement or under any other indemnification agreement if and to the extent that Indemnitee has otherwise actually received such payment under any insurance policy, contract, agreement or otherwise; provided,  however, that the Company hereby agrees that it is the indemnitor of first resort under this Agreement and under any other indemnification agreement (i.e., the Company’s obligations to Indemnitee under this Agreement or any other agreement or undertaking to provide advancement and/or indemnification to Indemnitee are primary with respect to any insurance that is or may become available to the Indemnitee).

(e)        The Company’s obligation to indemnify or advance Expenses hereunder to Indemnitee in respect of or relating to Indemnitee’s service at the request of the Company as a director, officer, employee, fiduciary, trustee, representative, partner or agent of the Company shall be reduced by any amount Indemnitee has actually received as payment of indemnification

-  9  -

or advancement of Expenses from such the Company, except to the extent that such indemnification payments and advance payment of Expenses when taken together with any such amount actually received from the Company or under director and officer insurance policies maintained by the Company or its subsidiaries are inadequate to fully pay all costs, Expenses or other items to the full extent that Indemnitee is otherwise entitled to indemnification or other payment hereunder.

(f)        Except as provided in Sections 11(c),  11(d) and 11(e) of this Agreement, the rights to indemnification and advancement of Expenses as provided by this Agreement shall not be deemed exclusive of any other rights to which Indemnitee may at any time, whenever conferred or arising, be entitled under applicable law, under the Company’s Articles of Association, or otherwise.  Indemnitee’s rights under this Agreement are present contractual rights that fully vest upon Indemnitee’s first service as a director or an officer of the Company.  The Parties hereby agree that Sections 11(c),  11(d) and 11(e) of this Agreement shall be deemed exclusive and shall be deemed to modify, amend and clarify any right to indemnification or advancement provided to Indemnitee under any other contract, agreement or document with the Company.

(g)        No amendment, alteration or repeal of this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee in Indemnitee’s Corporate Status prior to such amendment, alteration or repeal.

12.       Employment Rights; Successors.

(b)       This Agreement shall be binding upon the Company and its successors and assigns and shall inure to the benefit of Indemnitee and Indemnitee’s heirs, executors and administrators.  If the Company or any of its successors or assigns shall (i) consolidate with or merge into any other corporation, limited liability company or entity and shall not be the continuing or surviving corporation, limited liability company or entity of such consolidation or merger or (ii) transfer all or substantially all of its properties and assets to any individual, corporation or other entity, then, and in each such case, proper provisions shall be made so that the successors and assigns of the Company shall assume all of the obligations set forth in this Agreement.

13.       Severability.  If any provision or provisions of this Agreement shall be held to be invalid, illegal or unenforceable for any reason whatsoever:  (a) the validity, legality and enforceability of the remaining provisions of this Agreement (including without limitation, each portion of any Section of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby; (b) such provision or provisions shall be deemed reformed to the

-  10  -

extent necessary to conform to applicable law and to give the maximum effect to the intent of the parties hereto; and (c) to the fullest extent possible, the provisions of this Agreement (including, without limitation, each portion of any Section of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall be construed so as to give effect to the intent manifested thereby.

14.       Exception to Right of Indemnification or Advancement of Expenses.  Notwithstanding any other provision of this Agreement and except as provided in Section 7(a) of this Agreement or as may otherwise be agreed by the Company, Indemnitee shall not be entitled to indemnification or advancement of Expenses under this Agreement with respect to any Proceeding brought by Indemnitee (other than a Proceeding by Indemnitee (i) by way of defense or counterclaim or other similar portion of a Proceeding, (ii) to enforce Indemnitee’s rights under this Agreement or (iii) to enforce any other rights of Indemnitee to indemnification, advancement or contribution from the Company), unless the bringing of such Proceeding or making of such claim shall have been approved by the Board of Directors of the Company.

(h)       “Trinseo Entity” means the Company and any of its respective subsidiaries and any other corporation, partnership, limited liability company, joint venture, trust, employee benefit plan or other enterprise with respect to which Indemnitee serves as a director, officer, employee, partner, representative, fiduciary, trustee, or agent, or in any similar capacity, at the request of the Company.

Basis of Presentation

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 June 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 12 for further information.

Recent Accounting Guidance

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 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 process, information technology, and controls, and determining the quantitative impact resulting from the adoption of this new standard. 

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. This guidance is effective for public companies for annual and interim periods beginning after December 15, 2017, with early adoption permitted. This guidance must be adopted using a retrospective approach, and provides for certain practical expedients. Additionally, the FASB has issued further guidance related to the presentation of restricted cash on the consolidated statements of cash flows. While the Company continues to assess the timing and related impact of adopting this guidance on its consolidated statement of cash flows, the most significant expected impact on the Company’s financial statements will be the requirement to classify debt prepayment or extinguishment costs as financing cash outflows, as opposed to the Company’s prior classification of these types of costs within operating activities.

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 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.

NOTE 3—INVESTMENTS IN UNCONSOLIDATED AFFILIATES

During the six months ended June 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 June 30, 2017 and December 31, 2016, respectively, the Company’s investment in Americas Styrenics was $153.1 million and $149.7 million, which was $52.3 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 3.3 years as of June 30, 2017. The Company received dividends from Americas Styrenics of $37.5 million and $45.0 million during the three and six months ended June 30, 2017, respectively, compared to $30.0 million and $60.0 million during the three and six months ended June 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 six months ended June 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 June 30, 2017. The Company received dividends from Sumika Styron Polycarbonate of zero and $9.8 million during the three and six months ended June 30, 2017,  respectively, compared to  zero and $6.2 million during the three and six months ended June 30, 2016, respectively. The dividend received during the six months ended June 30, 2017 from Sumika Styron Polycarbonate related to the Company’s proportionate share of earnings for the year ended December 31, 2016.

Derivative Instruments [Abstract]

Derivative Instruments

NOTE 6—DERIVATIVE INSTRUMENTS

The Company’s ongoing business operations expose it to various risks, including fluctuating foreign exchange rates. To manage these risks, the Company periodically enters into derivative financial instruments such as foreign exchange forward contracts. 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 June 30, 2017, the Company had open foreign exchange forward contracts with a notional U.S. dollar equivalent absolute value of $302.1 million. The following table displays the notional amounts of the most significant net foreign exchange hedge positions outstanding as of June 30, 2017.

	June 30,

Euro	$	(146,217)
Chinese Yuan	$	(74,647)
Indonesian Rupiah	$	(33,617)
Swiss Franc	$	18,686
Japanese Yen	$	(7,706)

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 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 June 30, 2017 have maturities occurring over a period of 18 months, and have a net notional U.S. dollar equivalent of $255.0 million.

Net Investment Hedge

The Company’s outstanding debt includes €375.0 million of Euro Notes (refer to Note 5 for details). As of June 30, 2017, the Company has designated a portion (€280 million) of the principal amount of these Euro Notes as a hedge of the foreign currency exposure of the Issuers’ net investment in certain European subsidiaries. As this debt was deemed to be a highly effective hedge, changes in the Euro Notes’ carrying value resulting from fluctuations in the euro exchange rate were recorded as cumulative foreign currency translation loss of $10.2 million within AOCI as of June 30, 2017.

The Company recorded losses of $8.8 million and $10.5 million during the three and six months ended June 30, 2017, respectively, and losses of $2.1 million and gains of $1.0 million during the three and six months ended June 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 $7.3 million and $7.9 million during the three and six months ended June 30, 2017, respectively, and gains of $2.3 million and losses of $2.6 million during the three and six months ended June 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 June 30, 2017, the Company has no ineffectiveness related to its foreign exchange cash flow hedges. Further, the Company expects to reclassify in the next twelve months an approximate $4.7 million net loss from AOCI into earnings related to the Company’s outstanding cash flow hedges as of June 30, 2017 based on current foreign exchange rates.

Forward contracts are entered into with a limited number of counterparties, each of which allows for net settlement of all contracts through a single payment in a single currency in the event of a default on or termination of any one contract. As such, in accordance with the Company’s accounting policy, we record these foreign exchange forward contracts on a net basis by counterparty within the condensed consolidated balance sheet. Information regarding the gross amounts of the Company’s derivative instruments and the amounts offset in the condensed consolidated balance sheets is as follows:

Fair Value Measurements

Fair Value Measurements

NOTE 7—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.

The following table summarizes the basis used to measure certain assets and liabilities at fair value on a recurring basis in the condensed consolidated balance sheets as of June 30, 2017 and December 31, 2016.

Total fair value	$	—	$	12,171	$	—	$	12,171

The Company uses an income approach to value its derivative instruments, utilizing discounted cash flow techniques, considering the terms of the contract and observable market information available as of the reporting date. Significant inputs to the valuation for foreign exchange forward contracts and foreign exchange cash flow hedges are obtained from broker quotations or from listed or over-the-counter market data, and are classified as Level 2 in the fair value hierarchy.

NOTE 8—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 June 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 six months ended June 30, 2017:

	Six Months Ended
	June 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 six months ended June 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 six months ended June 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 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 11—DIVESTITURES

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 six months ended June 30, 2016, the Company recorded impairment charges for the estimated loss on sale of approximately $12.9 million within “Other expense (income), net” in the condensed consolidated statement of operations. These charges, which are subject to certain post-closing settlement activities, were allocated as $8.6 million, $4.0 million, and $0.3 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 $1.5 million received during the six months ended June 30, 2017.

Segments

NOTE 12—SEGMENTS

Effective October 1, 2016, the Company realigned its reporting segments to reflect the new model under which the business is now 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.

The reconciliation of income before income taxes to Segment Adjusted EBITDA is as follows:

Earnings Per Share

Earnings Per Share

NOTE 15—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 six months ended June 30, 2017 and 2016, respectively.

	Three Months Ended				Six Months Ended

* Refer to Note 10 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 0.3 million and 0.2 million for the three and six months ended June 30, 2017, respectively, and zero million and zero million for the three and six months ended June 30, 2016, respectively.

Basis of Presentation.

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 June 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 12 for further information.

(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.
