PART I

Item 1.    Business

Business

We are a leading global materials company engaged in the manufacture and marketing of synthetic rubber, latex, and plastics, including various specialty and technologically differentiated products. We have leading market positions in many of the markets in which we compete. We believe we have developed these strong market positions due to our technological differentiation, diverse global manufacturing base, long-standing customer relationships, commitment to sustainable solutions and competitive cost positions. We believe that growth in overall consumer spending and construction activity, increased demand in the automotive industry for higher fuel efficiency and lighter-weight materials, and improving living standards in emerging markets will result in growth in the global markets in which we compete. In addition, we believe our increasing business presence in developing regions such as China, Southeast Asia, and Eastern Europe further enhances our prospects.

We develop synthetic rubber, latex and plastics products that are incorporated into a wide range of our customers’ products throughout the world, including tires and other products for automotive applications, carpet and artificial turf backing, coated paper and packaging board, food packaging, appliances, medical devices, consumer electronics and construction applications, among others. We seek to regularly develop new and improved products and processes, supported by our intellectual property portfolio, designed to enhance our customers’ product offerings. We have long-standing relationships with a diverse base of global customers, many of whom are leaders in their markets and rely on us for formulation, technological differentiation, and compounding expertise to find sustainable solutions for their businesses. Many of our products represent only a small portion of a finished product’s production costs, but provide critical functionality to the finished product and are often specifically developed to customer specifications. We believe these product traits result in substantial customer loyalty for our products.

We operate our business in two divisions: Performance Materials and Basic Plastics & Feedstocks.  The Performance Materials division includes the following reporting segments: Synthetic Rubber, Latex, and Performance Plastics.  The Basic Plastics & Feedstocks division represents a separate segment for financial reporting purposes and includes styrenic polymers, polycarbonate, or PC, and styrene monomer.  In addition, the Basic Plastics & Feedstocks division includes the results of our two 50%-owned joint ventures, Americas Styrenics LLC, or Americas Styrenics, and Sumika Styron Polycarbonate Limited, or Sumika Styron Polycarbonate. The following chart provides an overview of this organizational structure:

We believe that this organizational structure reflects the nature of our Company by grouping together segments with similar strategies, business drivers and operating characteristics. Our two divisions are of similar size in terms of sales, but have different margin profiles, different strategic focus, different value drivers and different operating requirements.  By organizing in this way, we believe that we can best manage and operate the Company, focusing on accelerating the growth of our Performance Materials division and improving the profitability of our Basic Plastics & Feedstocks division.

Our major products include: styrene-butadiene latex, or SB latex, and styrene-acrylate latex, or SA latex, in our Latex segment; solution styrene-butadiene rubber, or SSBR, lithium polybutadiene rubber, or Li-PBR, emulsion styrene-

5

butadiene rubber, or ESBR, nickel polybutadiene rubber, or Ni-PBR, and neodymium polybutadiene rubber, or Nd-PBR, in our Synthetic Rubber segment; highly engineered compounds and blends products for automotive end markets, as well as consumer electronics, medical, electrical and lighting, which we collectively call consumer essential markets, or CEM, in our Performance Plastics segment; and PC, polystyrene, acrylonitrile-butadiene-styrene, or ABS, and styrene-acrylonitrile, or SAN, in our Basic Plastics & Feedstocks segment.

We have significant manufacturing and production operations around the world, which allows us to serve our global customer base. As of December 31, 2015, our production facilities included 34 manufacturing plants (which included a total of 80 production units) at 26 sites across 14 countries, including joint ventures and contract manufacturers. Our manufacturing locations include sites in high-growth emerging markets such as China and Indonesia. Additionally, as of December 31, 2015, we operated 11 research and development (“R&D”) facilities globally, including mini plants, development centers and pilot coaters, which we believe are critical to our global presence and innovation capabilities.

We are a global business with a diverse geographic revenue mix and significant operations around the world.

In 2015, we generated net sales of $3,972 million, Adjusted EBITDA of $492.0 million, Adjusted EBITDA excluding inventory revaluation of $550.3 million, and net income of $133.6 million. Additional information regarding Adjusted EBITDA and Adjusted EBITDA excluding inventory revaluation, including a reconciliation of these metrics to net income (loss), is included in Item 7 – Management’s Discussion and Analysis of Financial Conditions and Results of Operations.  

Prior to our formation in Luxembourg in 2010, the Styron business was wholly-owned by Dow. On June 17, 2010, we were acquired by investment funds advised or managed by Bain Capital and Dow Europe, which acquired an ownership interest in our parent company and sole shareholder, Bain Capital Everest Manager Holding SCA, which we refer to as our Parent. As of December 31, 2015, Dow Europe held an approximately 6.6% interest in our Parent. We continue to have a significant business relationship with Dow and rely on our agreements with Dow for certain operating

6

and other services, for the supply of raw materials used in the production of our products and for certain intellectual property rights. See “—Our Relationship with Dow.”

The following chart summarizes our corporate ownership structure as of December 31, 2015.

Our Competitive Strengths

We believe we have a number of competitive strengths that differentiate us from our competitors, including:

Leading Positions in Consolidating Markets

We have leading positions in several of the markets in which we compete, including the #1 position in SSBR in Europe and the #1 position in SB latex globally, and we are a leading global producer of plastics products, including polystyrene and PC. We attribute our strong market positions to our technologically differentiated products, the scale of our global manufacturing base, our long-standing customer relationships and our competitive cost positions.

The markets in which we compete are also highly consolidated and have continued to experience further consolidation over the last several years through the business combinations of BASF Group and Ciba Specialty Chemicals, Yule Catto & Co. plc and PolymerLatex GmbH (currently known as Synthomer plc), Omnova Solutions Inc. and Eliokem International SAS and the formation of Styrolution Group GmbH. As a result, from 2005 to 2015, over 580 kMT ofproduction capacity was eliminated in the SB latex markets in North America and Europe, which represented an approximate 30% reduction in production capacity since 2005. In 1990, the top three producers, measured by production capacity, in North America and Europe represented 68% and 49% of estimated regional capacity, respectively. As a result of the capacity rationalizations and consolidations, including those described above, the top three producers in each of North America and Europe represented over 70% of estimated regional production capacity in 2015.

Production capacity has also been reduced in several of our markets, including styrenics products. For example, from 2005 to 2015, the polystyrene industry experienced substantial capacity rationalization with more than 1,500 kMT of annual North America and Western Europe polystyrene capacity being eliminated during this time period, representing a reduction of approximately 25% of the 2005 total capacity in those regions.

Technological Advantage and Product Innovation

Most of our products are critical inputs that significantly impact the functionality, production costs and quality of our customers’ products. Many of our products are also differentiated by their performance, reliability, customization and value, which are critical factors in our customers’ selection and retention of materials suppliers. For example, our advanced SSBR and Nd-PBR technology is designed to reduce a tire’s rolling resistance, resulting in better mileage and fuel efficiency and lower carbon dioxide emissions while at the same time improving the tire’s wet-grip, a measure of braking effectiveness and traction. We believe these are key performance attributes sought by the end user and have become more easily identifiable through the growing adoption of tire labeling requirements by regulatory agencies, including formal adoption by the European Union in late 2012. These attributes also help in meeting European carbon dioxide emissions legislation requirements. Other jurisdictions have adopted or are considering similar legislation, including tire labeling requirements.

Our lightweight plastics materials also allow automotive companies to reduce weight in vehicles by substituting heavier structural parts with our products and thereby improving fuel efficiency for cars. Higher end automotive interior applications have also benefitted from utilizing our technology which has high aesthetic appeal and excellent scratch resistant characteristics. Energy use is also substantially reduced by using our plastic in lighting and other consumer applications.

Through our performance latex portfolio, we offer a variety of products designed to meet the needs of multiple applications, including adhesives, building and construction and composites, road, athletic, and automotive surfaces, technical fabrics and technical papers and boards. Our performance latex products are designed to enhance and improve an application’s mechanical properties, including water, chemical, stain, abrasion or oil resistance, cohesive and adhesive strength, or dimensional stability, flexibility, water impermeability and efflorescence resistance. Using our technological expertise, we typically launch one to two new technologies in our latex segment each year.

Diverse Global Reach with Strong Presence in Emerging Markets

As of December 31, 2015, our production facilities included 34 manufacturing plants (which included a total of 80 production units) at 26 sites in 14 countries, inclusive of joint ventures and contract manufacturers. We believe our diverse locations provide us with a competitive advantage in meeting and anticipating the needs of our global and local

8

customers in both well-established and growing markets. We have a strong presence in Asia, where we supply custom formulated latex products both for established and new paper mills, as well as a variety of engineered polymers, synthetic rubber and other products that are used in a variety of end-markets.

Long-Standing, Collaborative Customer Relationships

We have long-standing relationships with many of our customers, helping them to develop and commercialize multiple generations of their products. We have won numerous supplier awards across our segments. We believe we have developed strong relationships through our highly collaborative process, whereby we work with our customers, particularly in high-value segments such as SSBR, specialized plastics and performance latex, to develop products that meet their specific needs. As part of this process, we test our products at customer sites and work with customers to optimize and customize our product offerings. As a result of our close collaboration, we have historically achieved a high success rate of retaining customers. In 2015, we sold to approximately 1,350 customers in over 82 countries with no single customer accounting for more than 8.1% of our net sales in 2015.

Attractive Segments and End-Markets

We focus on what we believe are the most attractive segments for our customers’ products, or end-markets, where demand is underpinned by global trends supporting long-term volume growth, improving living standards in emerging markets, fuel efficiency and the increasing use of light-weight materials. We serve customers in a diversified mix of end-markets that we believe generally grow when global gross domestic product, or GDP, increases. Certain key regional markets where we have a strong presence are expected to outperform global growth rates.

We also believe that the relatively modest level of capacity additions that have been announced in the marketplace will contribute to increased demand for our production capacity and products.

Cost Competitive Assets and Raw Material Sourcing

We believe that our assets and raw material procurement provides us with a competitive cost position for our products. Our products are produced on a global scale with well maintained, productive and cost efficient assets. Some of our global facilities are positioned near some of our key customers or markets, while other facilities are located strategically near major integrated petrochemical centers or are co-located at large Dow facilities, where we benefit from receiving certain raw materials supplied to our facilities by pipeline. We also benefit from existing long-term supply contracts for raw materials including ethylene, butadiene, and benzene, which help us maintain consistent supply through varying market conditions.

The presence of some of our facilities on Dow manufacturing sites allows us to leverage Dow’s existing manufacturing infrastructure in an efficient manner, without the need for us to construct our own infrastructure or provide our own related site services. Dow pipelines directly supply raw materials to our facilities in Terneuzen, The Netherlands and Boehlen, Schkopau, and Stade, all in Germany. We share manufacturing infrastructure with Dow at these locations as well as in Midland, Michigan. At certain of our other facilities, we are able to limit the amount of our outbound freight costs as a result of the proximity of several of our facilities, including Dalton, Georgia, and Hamina, Finland, to key local customers.

We also seek to leverage our experience with styrene monomer (also referred to as “styrene”) to achieve the best possible cost position. We produce styrene in world scale facilities located in Terneuzen, The Netherlands and Boehlen, Germany. These assets have operated consistently in the 1st or 2nd quartile for energy and raw material efficiency as compared to other European ethylbenzene styrene monomer units. We also purchase styrene under high volume raw material cost-based contracts leveraging our buying power.

Experienced Management Team

Our executive leadership team averages over 25 years of industry experience, including leadership positions within our business units, and significant public company leadership experience at other chemical companies.

Our Growth Strategy

We believe that there are significant opportunities to grow our business globally and enhance our position as a leading global materials company engaged in the manufacture and marketing of standard, specialty and technologically differentiated emulsion polymers and plastics by executing on the following strategies:

Continue Product Innovation and Technological Differentiation

We intend to continue to address our customers’ critical materials needs by utilizing our technological expertise and development capabilities to create specialty grades, new and sustainable products and technologically differentiated formulations. We believe our technological differentiation positions us to participate in attractive, high growth areas of the markets in which we compete. One such area where we believe we have a technological advantage is enhanced SSBR. Enhanced SSBR technology, which includes later generations of SSBR and functionalized SSBR, is used in the latest generation of performance tires. The market for performance tires is expected to grow at a rate that is 2 to 3 times that of the standard tire market. We continue to devote significant R&D resources to improving and furthering our SSBR technology and our polybutadiene rubber technologies (such Nd-PBR and Li-PBR) in order to remain a leader in this market. For example, we have converted our Ni-PBR production capacity at our Schkopau, Germany facility to the production of a more advanced polybutadiene rubber, Nd-PBR, which is a key material in the latest generation of performance tires, and now are in the process of providing initial production batches and customer trials. Our development efforts are currently focused in large part on continuing to improve the fuel efficiency and performance characteristics of automotive tires.

We are also working with our industry partners, particularly in the automotive, medical devices, lighting and consumer electronics sectors, to develop new advanced plastics with the goal of gaining market share in higher value-added areas of the markets served by our Performance Plastics segment.

As a global leader in SB latex, we also continue to evaluate opportunities to expand our performance latex business by targeting particular end-markets and chemistries where we believe we have a competitive advantage, such as SB performance latex and styrene acrylics. We believe that performance latex accounts for a substantial portion of the total synthetic latex market, but only accounted for 9% of our Latex segment’s net sales in 2015, and we believe that we are well positioned to capture a larger share of this performance latex market.

Strategically Invest in Attractive Segments of the Market

We plan to make strategic capital investments to extend our leadership in select market segments and meet expected growing demand for our products. Our new SSBR production line in Schkopau, Germany began production on October 1, 2012, adding 50 kMT of new capacity. In addition, we repurchased 25 kMT of SSBR production capacity rights at our Schkopau facility from JSR Corporation Tokyo, Wallisellen Branch, effective March 31, 2014, at a significant discount to the estimated cost to build equivalent new capacity. With these two capacity additions, we have approximately doubled our SSBR production capacity.

As part of this strategy, we continue to divest from less attractive segments.  In September 2015, we announced plans to reduce operational costs in our Latex segment by a $5 million run rate in 2016 and to address declines in the coated paper market.  To this end, we closed our Allyn’s Point latex manufacturing facility in Gales Ferry, Connecticut at the end of 2015.

Opportunistically Pursue Strategic Acquisitions to Extend Leadership Positions

We intend to pursue acquisitions and joint ventures that have attractive risk-adjusted returns to extend our leadership positions in what we believe are the more attractive market segments (such as synthetic rubber and performance latex) and geographies for us, including emerging markets. We believe that a long-term trend toward consolidation in our industry will continue, which we expect to create opportunities for us given our scale, broad customer base, and geographic reach.

Continue to Implement Cost Saving Measures and Focus on Cash Flow Generation

We have a proven track record of offsetting fixed cost inflation with cost saving actions, and we continue to seek to identify incremental cost saving opportunities. In recent years, we have launched several company-wide initiatives

10

intended to further reduce our costs and increase our competitiveness. We have reduced our fixed cost base by almost $100 million since 2011 through a number of cost-saving initiatives such as streamlining production and administrative processes and optimizing logistics. We believe that our current cost structure positions us favorably to compete and grow in the current market environment, and we have ongoing corporate cost saving initiatives intended to realize annual cost savings at or above the rate of fixed cost inflation.

In addition, we continue to focus on cash flow generation through disciplined working capital and capital expenditure management. Following the completion of the SSBR capacity expansion at our Schkopau, Germany facility in 2012, capital expenditures have been reduced from approximately $112 million in 2012 to approximately $55 million in 2013, net of a $6 million and a $19 million government subsidy for SSBR expansion, respectively. Capital expenditures of $99 million in 2014, or only about 2% of sales, included $26 million for the acquisition of 25kMT of SSBR capacity from JSR. Additionally, capital expenditures were $109 million in 2015, or only about 2.7% of sales, and included $24 million related to the implementation of a new enterprise risk management system, expected to be completed in 2016, and the migration of certain of our manufacturing plants to a substitute third party process control technology.  We believe that our maintenance capital expenditures on our current fixed asset base will be in the range of $30 million to $40 million per year over the next several years, which represents less than 1% of our net sales.

Expand and Deepen Our Presence in Emerging Markets

We expect to capitalize on growing demand for our products in emerging markets such as China, Southeast Asia, and Eastern Europe and increase our local market share by expanding our customer base and extending local capabilities in some of these geographies. We believe that improving living standards and growth in GDP across emerging markets are creating increased demand for our products. We have also added an additional 25 kMT, or 33%, of SB latex capacity at our facility in Zhangjiagang, China, which became operational in the third quarter of 2015. We expect to leverage our existing technology and platforms to make additional investments in emerging markets to address expected increases in demand for our SSBR, performance latex and plastics products in those geographies. For example, we have recently committed to expanding our local performance plastics manufacturing capability in China, allowing us to supply ABS to customers locally in the world’s largest and fastest growing automotive market.  We also expect this growth to occur in the end markets that use our products.

We also expect to leverage our existing technology and platforms to make additional investments in emerging markets to address expected increases in demand for our SSBR, performance latex and plastics products in those geographies with growth prospects.

Latex Segment

Overview

We are a global leader in SB latex, holding a strong market position across the geographies and applications in which we compete, including the #1 position in SB latex in Europe with approximately 30% of Europe’s 898 kMT of SB latex capacity and the #2 position in North America with approximately 35% of its 477 kMT of capacity. We produce SB latex primarily for coated paper used in advertising and magazines, packaging board coatings, carpet and artificial turf backings, as well as a number of performance latex applications. In 2015 approximately 45% of our Latex segment’s sales were generated in Europe, 26% were generated in the United States, and the majority of the remaining net sales were in Asia.

We believe that our leading scale and differentiated capabilities in this segment are a competitive advantage that allows us to invest in new formulation capabilities and polymer science. Using our two pilot coating facilities in the United States and Switzerland, we work alongside our customers to develop new products and customer branding. We believe that this capability allows us to capture new business, strengthen our existing customer relationships and broaden our technological expertise. We continue to focus on our lower cost, starch emulsion technologies, which provide customers with similar performance as SB latex but at a cost advantage. We sold a record volume of this technology in 2015 and expect almost 20% volume growth in 2016 as we expand into additional applications and develop additional product offerings.

We believe our development and formulation capabilities contribute to our strong position. Further, we believe our growth prospects in latex are enhanced by our expanding capacity in China. Our strategic plans to meet the growing demand for latex in China’s paper and packaging board industry are ongoing. We believe that certain emerging markets, and in particular China, will contribute a substantial portion of the global growth of the paper and packaging board market segment over the next decade. 

We believe our growth prospects could also be enhanced if the recent trend of industry capacity reduction and consolidation continues. This consolidation trend includes the business combinations of BASF Group and Ciba Specialty Chemicals, Omnova Solutions Inc. and Eliokem International SAS, and Yule Catto & Co plc and PolymerLatex GmbH (currently known as Synthomer plc). We also believe we are well positioned to capture additional share in the performance latex market, which has accounted for a substantial portion of the total synthetic latex market, but only accounted for 9% of our Latex segment’s net sales in 2015.

Our strategy focuses on delivering consistent results by continuing to grow our volumes in Asia, in carpet, and in performance latex and to leverage our cost-advantaged position to minimize volume declines from the overall declines in the coated paper market in North America and Europe.

Products and End Uses

We are a global leader in the production and marketing of SB latex for coated paper with the #1 position in SB latex in Europe and the #2 position in North America. For coated paper, we primarily manufacture SB latex, a high-volume product that is widely used as a binder for mineral pigments as it allows high coating speeds, improved smoothness, higher gloss level, opacity and water resistance. Typically, SB latex formulations are engineered in close collaboration with customers, and are tailored specifically to optimize finished product properties and production efficiency, and to minimize mill down time. Since SB latex accounts for, on average, approximately 8% of the total production cost for coated paper but is a critical element of the manufacturing process and provides performance characteristics key to the product’s end-use, we believe customers view it as a crucial component of their manufacturing process and typically seek high-quality, reliable producers.

We are also a leading supplier of latex polymers to the carpet and artificial turf industries and offer a diverse range of products for use in residential and commercial broadloom, needlefelt, and woven carpet backings. We produce high solids SB latex, SA latex, vinylidene chloride, and butadiene-methacrylate latex products for the commercial and niche carpet markets. We incorporate vinyl acrylic latex in our formulations for its ignition resistant properties, with the sourcing of vinyl acrylic latex readily available from a number of industry suppliers. SB latex is also used in flooring as an adhesive for carpet and artificial turf fibers.

We also offer a broad range of performance latex products, including SB latex, SA latex, and vinylidene chloride latex primarily for the adhesive, building and construction as well as the technical textile paper market, and have begun to implement the use of starch and associated new chemistries in paper coatings and carpet backing.

Customers

We believe our Latex segment is able to differentiate itself by offering customers value-added formulation and product development expertise. Our R&D team and Technical Services and Development, which we refer to as TS&D, team are able to use our two pilot coating facilities in Switzerland and the United States, three paper fabrication and testing labs in China, Switzerland and the United States, three carpet technology centers located near carpet producers in China, the United States and Switzerland, and two product development and process research centers, one each in Germany and the United States, to assist customers in designing new products and enhancing the manufacturing process. Additionally, our global manufacturing capabilities are key in serving customers cost-effectively, as latex is costly to ship over long distances due to its high water content. We believe that our global network of service and manufacturing facilities is highly valued by our customers.

Many of our major customers rely on our dedicated R&D and TS&D teams to complement their limited in-house resources for formulation and reformulation tests and trials. We seek to capture the value of these services through our pricing strategy. We estimate that approximately half of net sales in this segment relate to contracts that include raw material pass-through clauses. In addition, as paper mills become larger and increasingly sophisticated with higher fixed costs, we believe there is greater demand for custom-formulated latexes. Historically, we have focused on capturing a majority share of new SB latex formulations for startups and major overhauls of existing paper coaters. In carpet applications, our product development expertise also allows us to provide differentiated products to our customers.

Competition

Our principal competitors in our Latex segment include BASF Group, Omnova Solutions Inc., Synthomer plc, and Lin Cham Ltd. In our Latex segment, we compete primarily based on our ability to offer differentiated products, the reliability of our products, the quality of our customer service and the length and depth of our relationships.

Industry Outlook

Certain changes in industry structure have had a beneficial effect for latex producers, driven by industry capacity reduction and consolidation. From 2005 to 2015 industry capacity in North America and Western Europe contracted approximately 30% due to shut downs and consolidations. Key industry events include the business combinations of BASF Group and Ciba Specialty Chemicals and resulting significant capacity reduction, a capacity rationalization by Dow / Dow Reichhold, Omnova Solutions Inc.’s rationalization at its Mogadore facility, the exit of The Lubrizol Corporation from the latex business, Omnova Solutions Inc.’s acquisition of Eliokem International SAS, and Yule Catto & Co. plc’s acquisition of PolymerLatex GmbH (currently known as Synthomer plc).

We also expect recent declines in the demand for coated paper to slow in the developed markets, particularly in Europe, and such declines to be partially offset by growth in emerging markets such as China, as improving living standards generate increased demand for coated paper end products, as well as growth in non-coated paper applications in all regions. Chinese consumption of styrene-butadiene latexes to paper and packaging board markets is expected to grow by an average of over 4% annually through 2020. Declines in the demand for coated paper resulted in efforts by us to rationalize our capacity by closing our Allyn’s Point latex manufacturing facility in Gales Ferry, Connecticut at the end of 2015.

In addition, several historical developments that appeared to have an unfavorable impact at first, including the emergence of substitutes for SB latex in carpet backing applications in North America, have had less of an impact than initially anticipated due to superior SB latex performance, as many customers that we believe have switched to substitute products have switched back to SB latex due to its superior quality. This trend has been bolstered by increased butadiene availability and decreased butadiene cost in recent years. We also anticipate the housing recovery in the U.S. market will benefit our SB latex business through increased demand for carpet backing applications. We believe that if the recent trends of industry capacity reduction and consolidation and increasing demand in emerging markets continue, this will lead to a favorable production environment.

Synthetic Rubber Segment

Overview

We are a significant producer of styrene-butadiene and polybutadiene-based rubber products and we have a leading European market position, providing approximately 70% of Western Europe’s 240 kMT SSBR capacity available for sale, and in synthetic rubber overall. While substantially all of our sales were generated in Europe in 2015, approximately 19% of these net sales were exported to Asia, 7% to Latin America and 9% to North America.

We have a broad synthetic rubber technology and product portfolio, focusing on specialty products, such as SSBR Li-PBR, and Nd-PBR, while also producing core products, such as ESBR. Our synthetic rubber products are extensively used in tires, with approximately 83% of our net sales from this segment in 2015 attributable to the tire market. We estimate that three-quarters of these sales relate to replacement tires. We have strong relationships with many of the top global tire manufacturers and believe we have remained a supplier of choice as a result of our broad rubber portfolio and ability to offer technologically differentiated product and product customization capabilities. Other applications for our synthetic rubber products include polymer modification and technical rubber goods.

Our most advanced rubber technology, SSBR, is a critical material for tires with low rolling resistance, which increases fuel efficiency and improves wet-grip and also leads to better traction and safety characteristics. Our fourth generation functionalized SSBR can improve traction by approximately 45% and rolling resistance by approximately 75% compared to our first generation. We believe our growth prospects are enhanced by increasing demand for high performance tires, which are now more commonly used by automakers as OEM specified tires in their vehicles as a result of regulatory reforms in the EU, Japan and Korea that are aimed at improving fuel efficiency and reducing carbon dioxide emissions. As a result of these and other factors, demand for SSBR is expected to grow substantially faster than global GDP over the next 5 years.

We remain committed to being a technology leader in providing products to the rapidly growing performance tire market, which is expected to grow at approximately 2 to 3 times the growth rate of the standard tire market. Our strategy in this market focuses on developing and commercializing new performance rubber grades and shifting the mix of products we sell toward more differentiated, higher margin products. Consistent with this strategy, we have doubled our production capacity of SSBR since 2012. This additional capacity enabled us to grow our SSBR sales volumes by 14% in 2015. Within our SSBR product family, our sales volume of enhanced SSBR grew 24% in 2015, and now represents 57% of our total SSBR sales volume, up from 38% in 2012. This mix shift has resulted in Adjusted EBITDA margins improving from 16% in 2012 to 20% in 2015.  

In addition, we continue to make investments to grow this segment. In 2014 we purchased an additional 25 kMT of SSBR production capacity rights at our Schkopau facility and in 2015 we completed the conversion of our Ni-PBR line to higher margin Nd-PBR and are currently running trial batches. We also continue to focus on remaining a technology leader in SSBR, providing superior tread properties such as wet grip, low rolling resistance, and reduced noise.

Products and End Uses

Our Synthetic Rubber segment produces synthetic rubber products used in high-performance tires, impact modifiers and technical rubber products, such as conveyor belts, hoses, seals and gaskets. We participate significantly in the European synthetic rubber industry, where tire producers focus on high-performance and ultra high-performance tires and rely heavily on rubber suppliers to provide their supply of rubber, in contrast to North America where tire manufacturers produce most of their required rubber.

SSBR. We sell SSBR products for high-performance and ultra high-performance tire applications. We produce both clear and oil extended SSBR through batch polymerization in our three SSBR production lines. We believe these processes provide leading and technologically differentiated solutions to tire manufacturers.

We believe we are well-positioned to capture additional market share in high-growth, high-performance tire applications and have expanded capacity to meet this anticipated demand. Our new SSBR production line in Schkopau, Germany began production on October 1, 2012, and expanded our SSBR production capacity by 50 kMT. In addition, we repurchased 25 kMT of SSBR production capacity rights at our Schkopau facility from JSR Corporation Tokyo, Wallisellen Branch, effective March 31, 2014, at a significant discount to the estimated cost to build equivalent new capacity. With these two capacity additions, we have approximately doubled our SSBR production capacity for this higher-margin product.

15

Our synthetic rubber portfolio is anchored by our SSBR technology and further strengthened by our new functionalized SSBR (SSBR engineered to perform specific functions) product offering. Our new product platform is used in the manufacture of high-performance and ultra high-performance tires. In Europe, we expect demand growth for performance tires, which are designed to improve passenger safety, tire longevity and vehicle fuel efficiency, to accelerate due to European legislation that became effective late in 2012.

During the last six years, we have been working closely with major tire producers around the world to develop multiple new SSBR grades, addressing key marketplace needs for improved tire fuel economy, grip, and abrasion characteristics, which we believe will lead to significant demand growth for our rubber products in Europe and around the world. We expect our synthetic rubber product mix to shift to new more advanced SSBR grades (from approximately 8% of total Synthetic Rubber volume sold in 2011 to 27% in 2015) to meet the expected demand growth. In 2015, SSBR represented approximately 58% of total segment net sales.

ESBR. OurESBR products are used in standard tires, technical goods, and footwear. Our ESBR product portfolio offers tire producers a comprehensive suite of synthetic rubber capabilities. For example, ESBR provides enhanced wet grip to tire treads and strength to the inner liner of tires, allowing the tires to be more easily processed. In 2015, ESBR represented approximately 34% of total segment net sales.

Ni-PBR and Nd-PBR. Throughout much of 2015, we sold Ni-PBR products for use in standard tires, performance tires, technical goods and footwear.  In 2015, Ni-PBR represented approximately 7% of total segment net sales. In November 2015, we completed the conversion of our Ni-PBR production capacity at our Schkopau, Germany facility to the production of a more advanced, higher margin polybutadiene rubber, Nd-PBR, and are currently running trial batches.  Nd-PBR is a key material in the latest generation of performance tires, and will also be sold for use in industrial rubber goods and polymer modification.

Li-PBR. Our Li-PBR is used primarily for our own internal polymer modification applications. Polymer modification is the use of synthetic rubber to improve the impact resistance quality of plastic products. In 2015, approximately 86% of our Li-PBR products were consumed within our Plastics business unit for high impact polystyrene, or HIPS, and ABS production. We make two grades of Li-PBR exclusively for our polymer modification uses. In addition to impact resistance, Li-PBR provides visual surface gloss. In 2015, Li-PBR represented approximately 1% of total segment net sales.

Customers

We maintain deep and long-standing relationships with a large number of multinational customers, including many of the top global tire manufacturers, as well as fast growing Asian tire manufacturers. Our relationships with our top customers, including with our predecessor business operated by Dow prior to the Acquisition, exceed 10 years on average.

Tire producers are the primary customers for our Synthetic Rubber segment. We believe we have remained a supplier of choice given our broad rubber portfolio, including technologically differentiated grades, and our product customization capabilities. The majority of our Synthetic Rubber segment net sales are based on contracts that generally include terms for at least three different rubber product families. In addition, we estimate that approximately 85% of net sales in this segment relate to contracts that include raw material pass-through clauses. Our R&D and TS&D teams use our broad rubber portfolio to develop differentiated specialty products for customers. Once implemented with a customer, these newly-developed specialty products cannot be easily replaced with a competitor’s product. As a result, we believe customers are likely to buy from us throughout the life cycle of specific tire models to avoid high switching costs and prevent repetition of the expensive development process.

Competition

Our principal competitors in our Synthetic Rubber segment include Asahi Kasei Corporation, JSR Corporation, Lanxess AG, Zeon Corporation, Versalis S.p.A and Synthos S.A. In our Synthetic Rubber segment, we compete primarily based on our ability to offer differentiated products, the reliability of our products, the quality of our customer service and the length and depth of our relationships.

Industry Outlook

Our Synthetic Rubber segment participates mainly in the European synthetic rubber industry, where tire producers rely on rubber suppliers, in contrast to North America where tire manufacturers produce most of their required rubber. Rubber suppliers typically manufacture more than one grade of rubber as customers typically require different grades of rubber from a single supplier. Performance tires represent an especially attractive market to rubber producers because they provide substantial value to end customers and the market for performance tires is expected to grow at a rate that is 2 to 3 times that of the standard tire market. Tire manufacturers are expected to continually seek improvements in advanced rubber, which optimizes the combination of fuel economy and wet grip in order to meet EU regulations which set minimum requirements and are being phased in through 2020. Other jurisdictions have adopted or are considering similar legislation and are also beginning to adopt the tire labeling requirements that have become mandatory in Europe since late 2012. In late 2014, the United Nation’s World Forum on Automotive Regulations adopted new internationally harmonized rules, known as Global Technical Regulations (GTR) for passenger car tires applicable in the European Union, China, Canada, India, Japan and Russia. Enhanced SSBR, which includes later generations of SSBR and functionalized SSBR and is used in the new generation of performance tires, is expected to approach 50% of the total SSBR market by 2018. We believe our leadership in the fast growing SSBR segment will position us to perform well relative to the broader industry and anticipate future strong demand from the broader adoption of legislation similar to the EU legislation and the relative performance advantages of our SSBR products.

We believe that demand for enhanced SSBR will grow at a rate of approximately 11% through 2020, outpacing supply, and resulting in an expected increase in industry utilization rates. This anticipated increase in demand is further evidenced by Goodyear’s April 2015 announcement that it will build a new plant in Mexico to meet the growing demand for premium tires.  This announcement indicated that the new plant will supply 6 million tires per year when it opens in mid-2017, and supplements Goodyear’s other initiatives to supply more premium tires, including an initiative to convert standard tire production into premium tire production. 

Performance Plastics Segment

Overview

We are a producer of highly engineered compounds and blends for automotive end markets, as well as consumer electronics, medical, electrical, and lighting, which we collectively call consumer essential markets (CEM). Our strategy in this segment focuses on developing differentiated compounds and blends in line with key industry trends, such as light-weighting and improved aesthetics in automotive, increased recycled material content and a push toward LED lighting in CEM.

Our manufacturing facilities are located across Europe, Asia, and North America. We believe that the strategic locations of these facilities combined with close customer collaboration offers us a strategic advantage in serving our customers. More than half of our compounds and blends products are differentiated based on their physical properties, performance and aesthetic advantages. Our history of innovation has contributed to long-standing relationships with customers who are recognized leaders in their respective end-markets. We have established a strong market presence in the global automotive and electronics sector, targeting both component suppliers and final product manufacturers. Our Performance Plastics segment also compounds and blends our PC and ABS plastics into differentiated products for customers within these sectors, as well as into compounds of polypropylene. We have also developed compounds containing post-consumer recycle polymers to respond to what we believe is a growing need for some customers to include recycled content in their products.

We believe growth in this segment is driven by a number of factors, including consumer preference for lighter weight and impact-resistant products and the development of new consumer electronics, increases in LED lighting applications and continuing growth in medical device applications. Additionally, we believe growth is bolstered by sustainability trends, such as the substitution of lighter-weight plastics for metal in automobiles, as well as more energy efficient, glazing solutions.

In 2015, approximately 38% of our Performance Plastics segment’s net sales were generated in Europe, approximately 27% were generated in the United States and approximately 22% were generated in Asia, with the remainder in other geographic regions, including Latin America and Canada.

In automotive end applications, we aim to maintain and develop sustainable, long-standing relationships with industry leaders, taking advantage of our production capacity on four continents to drive OEM platform design wins. In

17

2015, we experienced growth in key markets, with a 2% increase in volume outside of Latin America, which experienced declines due to lower consumer confidence and higher interest rates. We continue to focus on our strategic plans to grow this segment through both current technologies and expanded offerings for car exteriors and semi-structural applications.

In CEM, sales volume for 2015 was up 9% over 2014, driven largely by the consumer electronics industry in Asia and by significant progress during the year with our lighting customers, including materials for LED housings and lenses.

Products and End Uses

Our Performance Plastics segment consists of compounds and blends and some specialized ABS grades. We have a significant position in PC/ABS blends, which combine the heat resistance and impact strength of PC with the easy to process qualities and resilience of ABS. We believe our ability to offer technologically differentiated products to meet customer needs sets us apart from our competitors, and with our history as a leading innovator in compounds and blends, we have established ourselves as a leading supplier of PC-based products.

For the automotive industry, we manufacture PC blends under the PULSE™ brand, and we innovate collaboratively with our customers to develop performance solutions to meet the industry’s needs, such as removing weight from vehicles. As a result, we are a key supplier of these products to leading automotive companies in North America and Europe, who tend to specify these products on a per car program platform basis, making it difficult to be displaced as a supplier once selected and providing us with relatively stable and predictable cash flows for several years during the production lifecycle. We are also accelerating our development of similar supply capabilities in growing areas such as China.

For the consumer electronics, electrical and lighting and medical device industries, we manufacture our products under the EMERGE™ brand, among others, and we believe that we have substantial growth opportunities in tablets, notebooks, smart phones and other handheld devices, and electrical and lighting and medical device components. In serving these markets, we leverage our polymer and compound technologies to meet increasingly stringent performance requirements along with the aesthetic and color-matching requirements which are crucial characteristics for the products involved. The result is that we are a leading and long-standing supplier to many well-known brands.

Customers

We have a history of innovation in our Performance Plastics segment, and we believe that our focus on differentiated products enhances our growth prospects in this segment. We develop tailored polymer, compound and process solutions for our customers and for end-markets such as consumer electronics, we believe that our ability to work with our customers to quickly and effectively develop product solutions is a key to our success. Our innovation has contributed to long-standing relationships with customers who are recognized leaders in their respective end-markets. We also believe our global facilities are a competitive advantage that allows us to provide customers with consistent grades and position us to strategically serve emerging markets.

Competition

Our principal competitors in our Performance Plastics segment are Covestro AG, LG Chem Ltd., Mitsubishi Chemical Corporation, Saudi Basic Industries Corporation, Teijin Limited, Borealis AG, Celanese Corporation, Styrolution Group, and LyondellBasell Industries. In our Performance Plastics segment, we compete primarily based on our ability to offer differentiated products, the reliability of our products, the quality of our customer service and the length and depth of our relationships.

Industry Outlook

We believe that automotive manufacturers will continue the practice of lightweighting vehicles in order to meet increasing fuel efficiency standards, which should increase demand for our compounds and blends products. The plastic content in cars is expected to increase at an average rate of approximately 10% per year from 2014 to 2020. We believe these same trends towards lighter weights and higher performance materials will also impact other key end-markets such as medical devices, lighting and consumer electronics, and demand for our differentiated products in these markets is expected to grow at an average rate of approximately 9% per year from 2015 to 2020.

Basic Plastics & Feedstocks Segment

Overview

Basic Plastics & Feedstocks consists of styrenic polymers, including polystyrene, ABS, and SAN products, as well as PC and styrene monomer, which includes our internal production and sourcing of styrene. We do not anticipate investing in strategic growth initiatives in this segment in the near term. Rather, our strategy for this segment is focused on operational enhancements, margin improvement, and cash generation.

Also within this segment, our 50%-owned joint venture, Americas Styrenics, continues to be a leading producer in North America of both styrene and polystyrene. We have received $125 million in cash dividends from Americas Styrenics during the year ended December 31, 2015. The results of Sumika Styron Polycarbonate, our other 50%-owned joint venture, are also included within the results of our Basic Plastics & Feedstocks segment. As of the end of 2015, we have not received cash dividends from Sumika Styron Polycarbonate since the first quarter of 2014.

We are a leading producer of polystyrene and ABS, where we focus our efforts on differentiated applications such as the liners and encasements of appliances and consumer electronics including smartphones and tablets. Within these applications, we have worked collaboratively with customers to develop more advanced grades of plastics, such as our HIPS and mABS products. For example, we work with appliance manufacturers around the world to develop improved environmental stress crack resistant products and with our construction sheet customers on smooth ABS. These products offer superior properties, such as rigidity and colorability, and, in some cases, an improved environmental footprint compared to general purpose polystyrene or emulsion ABS. Our Basic Plastics & Feedstocks segment also serves the packaging and construction end-markets, where we have launched a new general purpose polystyrene product for improved performance in foam insulation applications. Today, we are one of the top 3 polystyrene producers worldwide, providing, either directly or through Americas Styrenics, approximately 20% of Europe’s polystyrene capacity of 2,192 kMT, approximately 4% of Asia’s capacity of 7,921 kMT and approximately 29% of North America’s capacity of 2,579 kMT. In 2015, we also supplied 17% and 15% of the styrene monomer capacity out of 6,022 kMT and 5,455 kMT in North America and Europe, respectively.

Within styrene monomer, we believe there is a current and longer term trend towards higher styrene margins, due to demand growth, an aging industry asset base, and limited new capacity expected over the next five years. Global styrene operating rates were 84% in 2015 and are forecasted to rise to 87% by 2020. These relatively high operating rates can result in periods of elevated margins due to planned or unplanned production outages. For example, approximately 20% of Western European capacity was offline at times during 2015, which, combined with customer restocking in polystyrene derivatives, resulted in increased margins during the year. We believe there is continued potential for periods of elevated, outage-driven styrene margins given that approximately 60% of Western Europe styrene production capacity is greater than 20 years old, and nearly 40% is more than 30 years old. The following chart illustrates historical styrene margins in Western Europe:

19

The following charts represent historical styrene, benzene, and ethylene prices, as well as styrene margin, over raw materials, which is calculated by subtracting the costs of benzene and ethylene from the sales price of styrene.

20

Source: IHS. Styrene: W. Europe Contract Monthly Market (Delivered W. Europe); Benzene: 50% W. Europe Spot Avg. (CIF NW Europe / Basis ARA) and 50% W. Europe Contract – Monthly Market (FOB/CIF W. Europe); Ethylene: W. Europe Contract – Market Pipeline (Delivered W. Europe). Styrene: NE Asia Avg. Spot Posting (CFR China); Benzene: NE Asia Spot Avg. (FOB S. Korea); Ethylene: NE Asia Spot Avg. (CFR NE Asia). Margin: Styrene less 80% Benzene less 30% Ethylene.

We capture styrene monomer margin through both internally produced and cost-based purchases of styrene. Annually, we produce approximately 600 kilotons of styrene in Western Europe and purchase approximately 300 kilotons of styrene in Asia with cost based economics. With all other inputs remaining equal, a $50 per metric ton change in styrene margins would be expected to impact our annual Adjusted EBITDA by approximately $30 million in Europe and approximately $15 million in Asia.

We are a producer of PC and PC blends, supplying 3% of polycarbonate capacity of 2,413 kMT in Asia through our Sumika Styron Polycarbonate joint venture, and 13% of 1,210 kMT in Europe. In late 2014, we exited the contract manufacturing agreement with Dow at their Freeport, Texas facility. Smaller competitors tend to operate on a regional basis. We have developed a global, multi-tiered marketing approach targeting the tiered suppliers, as well as final product producers, which we believe most effectively addresses our customers’ needs.

We believe our growth prospects in our Basic Plastics & Feedstocks segment are enhanced by periodic trends of industry capacity reduction and consolidation in Europe and North America, such as the 2011 formation of the Styrolution Group GmbH joint venture combining certain INEOS and BASF Group assets and the prior acquisition of INEOS Nova by INEOS, as well as INEOS’ most recent asset rationalizations in styrene monomer and polystyrene and Styrolution’s recent announcements to close polystyrene plants in the United States and Sweden. We also have a 50% interest in Americas Styrenics LLC, our joint venture with Chevron Phillips Chemical Company, which operates in the North American and Latin American markets and has benefitted from recent positive trends in those markets. We expect further consolidation in certain regions of Asia with numerous producers and low asset utilization, which we believe will create opportunities for us, given our scale and geographic reach. We believe our growth prospects are further enhanced by our established manufacturing footprint in the high economic growth regions of Asia and our focus on attractive end-markets where improving living standards drive demand for growing appliances, building and construction, and consumer electronics markets.

During the second quarter of 2014, the Company announced a planned restructuring within its Basic Plastics & Feedstocks segment to exit the commodity market for polycarbonate in North America and to terminate existing arrangements with Dow regarding manufacturing services for the Company at Dow’s Freeport, Texas facility. The Company also entered into a new long-term supply contract with a third party to supply polycarbonate in North

21

America. These revised arrangements became operational in the fourth quarter of 2014. In addition, the Company has executed revised supply contracts for certain raw materials that are processed at its polycarbonate manufacturing facility in Stade, Germany, which took effect beginning January 1, 2015. These revised agreements facilitated improvements in our results of operations for our Basic Plastics & Feedstocks segment during 2015.

Our PC business has benefitted and will continue to benefit from higher global utilization rates.  Large capacity additions in 2011 and 2012 by SABIC and other producers decreased industry operating rates to 74% in 2013.  However, continued demand growth, coupled with capacity expansion delays and capacity reductions, have increased global utilization rates to greater than 80%.  This resulted in significantly higher PC margins in 2015.  We expect these higher margins to occur in the future as demand growth is expected to exceed that of supply. A $100 per metric ton change in polycarbonate margins would be expected to result in approximately a $15 million change in our annual Adjusted EBITDA.

In 2015, approximately 66% of sales from our Basic Plastics & Feedstocks segment were generated in Europe and an additional 28% of sales were generated in Asia.

Products and End Uses

Polystyrene. We are a leading producer of polystyrene and focus on sales to injection molding and thermoforming customers. Our product offerings include a variety of general purpose polystyrenes, or GPPS, and HIPS, which is polystyrene that has been modified with polybutadiene rubber to increase its impact resistant properties. These products provide customers with performance and aesthetics at a low cost across applications, including appliances, packaging, including food packaging and food service disposables, consumer electronics and building and construction materials.

We believe our STYRON™ brand is one of the longest established brands in the industry and is widely recognized in the global marketplace. We believe our R&D efforts have resulted in valuable, differentiated solutions for our customers. For instance, during the early 2000s, we developed an innovative STYRON A-TECH™ family of resins that is an advanced polystyrene product allowing customers to balance key properties such as toughness, gloss, stiffness, flow and cost, and provide combinations of properties that were previously not available with standard HIPS. We believe that over the past decade, this product family has become the industry standard for this application.

Acrylonitrile-Butadiene-Styrene (ABS). We believe we are a leading producer of ABS in Europe and are one of the few producers with a presence in North America. We produce mABS, a variation of ABS that has lower conversion and capital costs compared to the more common emulsion ABS, or eABS, process, marketed under the MAGNUM™ brand. mABS has similar properties to eABS but has greater colorability, thermal stability and lower gloss. mABS products can be manufactured to stricter specifications because it is produced in a continuous process as opposed to the batch process used in eABS. mABS also has environmental benefits such as waste reduction and higher yields. In addition to our own mABS production capacity, we also license our proprietary mABS technology to other producers.

Primary end uses for our ABS products include automotive and construction sheet. We maintain a significant share of ABS sales into these markets, which we believe is driven by the differentiating attributes of our mABS products, our reputation as a knowledgeable supplier, our broad product mix and our customer collaboration and design capabilities.

Automotive manufacturers have developed innovative solutions in order to meet increasing fuel standards, such as the lightweighting of vehicles. Consequentially, manufacturers have been replacing heavier materials with durable yet lighter materials, such as mABS and polypropylene compounds. We expect this trend to continue, and we believe that our technological capabilities in our Basic Plastics & Feedstocks segment together with our compounding and blending expertise will help generate future growth opportunities.

Styrene-Acrylonitrile. SAN is composed of styrene and acrylonitrile, which together provide clarity, stiffness, enhanced ability to be processed, mechanical strength, barrier properties, chemical resistance and heat resistance.

SAN is used mainly in appliances, consumer goods and construction sheets, due to its low-cost, clarity and chemical resistance properties. Within our Basic Plastics & Feedstocks segment, we manufacture SAN under the TYRIL™ brand name for use in housewares, appliances, automotive, construction sheets, battery cases and lighting applications. In addition, TYRIL™ is suitable for self-coloring which adds value in many of these uses.

Polycarbonate.  PC has high levels of clarity, impact resistance and temperature resistance. PC can be used in its neat form (prior to any compounding or blending) for markets such as construction sheet, optical media and LED

22

lighting. Additionally, PC can be compounded or blended with other polymers, such as ABS, which imparts specific performance attributes tailored to the product’s end-use.

Our products for glazing and construction sheets are marketed under the CALIBRE™ brand name and offer customers a combination of clarity, heat resistance and impact performance. Glazing and construction sheet represents our largest PC application, and is a key growth focus for us. Key end-markets include the construction industry, with additional opportunities for growth with compounded products in the medical device space, consumer electronics and other applications such as smart meter casings that require plastics with enhanced weatherability, ignition resistance and impact performance.

Customers

Our customer centric model focuses on understanding customers’ needs and developing tailored solutions that create value for both parties. For durable applications, we focus our TS&D, R&D and marketing teams on product design engineering initiatives for developing and specifying plastics in the next generation of construction applications, appliances, automotive, and consumer electronics. In non-durable applications, we focus on innovative products that provide clear cost advantages to our customers, serving customers with our cost-advantaged technology and operating excellence. We have leveraged industry-leading product development and technology capabilities to develop long-standing customer relationships with many of our customers, including a number who have purchased from us, including our predecessor business operated by Dow prior to the Acquisition, for more than 20 years. We believe that our global presence is an advantage, allowing us to provide customers with consistent product grades and positioning us to strategically serve growth economies.

Competition

Our principal competitors in our Basic Plastics & Feedstocks segment are Styrolution Group GmbH, Versalis S.p.A., Total S.p.A., Covestro AG, LG Chem Ltd., Mitsubishi Chemical Corporation, Formosa Plastics Corporation, Saudi Basic Industries Corporation,Shanghai SECCO Petrochemical Company Limited, and Chi Mei Corporation. In our Basic Plastics & Feedstocks segment, we compete primarily based on our ability to offer differentiated products, the reliability of our products, the quality of our customer service and the length and depth of our relationships.

Industry Outlook

From 2005 to 2015, the polystyrene industry experienced substantial capacity rationalizations by major producers such as BASF Group, INEOS Nova, and others. More than 1,500 kMT of annual North American and Western European polystyrene capacity was eliminated during this time period, representing a reduction of approximately 30% of the 2005 total capacity in those regions. Consistent with the broader industry, we participated in these rationalizations by electing to shut down some of our less cost effective European assets and concentrating production at our most competitive facilities.

In addition to improving profitability through cost rationalizations, the polystyrene industry has also benefited from a number of consolidating activities. A number of our larger competitors have enhanced their platforms via acquisitions and joint ventures, such as the 2011 formation of the Styrolution joint venture combining certain INEOS and BASF Group assets and the prior acquisition of INEOS Nova by INEOS. Global utilization rates are expected to steadily improve as the reduced production capacity serves growing demand in end-markets.

The ABS and styrenics markets have also experienced a number of capacity rationalizations since 2006. These rationalizations, combined with improved end-market demand, have resulted in a substantial improvement in operating rates since the beginning of the global economic downturn. The rise in global operating rates for styrene monomer are driven by limited, if any, investment in new capacity and continued growth especially in large markets like China.

These styrene and polystyrene dynamics will also benefit our 50%-owned joint venture, Americas Styrenics.  The North America polystyrene market is more consolidated than those in Europe and Asia, and Americas Styrenics has approximately 29% of the capacity in the region, at the top of all producers.  Americas Styrenics is focused on optimizing profitability and distributing cash dividends to its parent companies.

Our PC business has benefitted and will continue to benefit from higher global utilization rates. Large capacity additions in 2011 and 2012 by SABIC and other producers decreased industry operating rates to 74% in 2013.  However,

23

continued demand growth, coupled with capacity expansion delays and capacity reductions, have increased global utilization rates to greater than 80%. This resulted in significantly higher PC margins in 2015.  We expect these higher margins to occur in the future as demand growth is expected to exceed supply.

Our Relationship with Dow

In conjunction with the Acquisition and subsequently, we entered into certain agreements with Dow, including the Second Amended and Restated Master Outsourcing Services Agreement, which was modified on June 1, 2013 (“SAR MOSA”), the Amended and Restated MOD5 Computerized Process Control Software, Licenses and Services Agreement, with Rofan Services, Inc. which was modified June 1, 2013 (“AR MOD5 Agreement”), site and operating services agreements, and supply agreements.

The SAR MOSA provides for ongoing worldwide services from Dow, in areas such as information technology, enterprise resource planning, finance, environmental health and safety, training, customer service, marketing and sales support, supply chain and certain sourcing and transactional procurement services. The term of this agreement runs through December 2020 and which automatically renews for two year periods unless either party provides six months’ notice of non-renewal to the other party. The services provided pursuant to the SAR MOSA generally are priced per function, and we have the ability to terminate the services or any portion thereof, for convenience any time after June 1, 2015, subject to payment of termination charges. Services which are “highly integrated” follow a different process for evaluation and termination. In addition, either party may terminate for cause, which includes a bankruptcy, liquidation or similar proceeding by the other party, for material breach which is not cured, or by Dow in the event of our failure to pay for the services thereunder. In the event of a change of control, as defined in the agreement, Dow has the right to terminate the SAR MOSA.

Under the AR MOD5 Agreement, Dow provides worldwide process control technology, including hardware, software licenses and support services, and related enterprise resource planning services. The AR MOD5 Agreement, with a term through December 2020, may be terminated by either party for cause, which includes a bankruptcy, liquidation or similar proceeding by the other party, for material breach which is not cured by us if we no longer wish to receive maintenance and support for any licensed software; or by Dow if we use the licensed software for any purposes other than Company business. Dow may terminate the maintenance and support terms at any time if we fail to make payments when due and the default is not corrected within 30 days from notice, or upon two years written notice us, if Dow has made the decision not to support the software systems, provided that Dow will use commercially reasonable efforts to assist us in locating and transitioning to an alternate service provider. We have started to move our plants off the AR MOD5 process control technology through a strategic external relationship with ABB Ltd. and have successfully completed five plant conversions to date.  We continue to work through our established schedule for plant conversions off of the AR MOD5 process control technology, which we expect to be completed in 2020.

In addition, we entered into various site services agreements with Dow, which were modified as of June 1, 2013, (the “Amendment Date”) where at Dow owned sites, Dow provides site services to Company. Conversely, we entered into similar agreements with Dow in June 2010, where at Company owned sites, we provide such services to Dow. These agreements cover general services that are provided at specific facilities co-located with Dow, rather than organization-wide services, and include utilities, site administration, environmental health and safety, site maintenance and supply chain. In certain circumstances, the parties may adjust certain prices and volumes. These agreements generally have 25-year terms from the Amendment Date, with options to renew. These agreements may be terminated at any time by agreement of the parties, or, by either party, for cause, including a bankruptcy, liquidation or similar proceeding by the other party, or under certain circumstances for a material breach which is not cured. In addition, we may terminate for convenience any services that Dow has agreed to provide to us that are identified in any site services agreement as “terminable” with 12 months prior notice to Dow, dependent upon whether the service is highly integrated into Dow operations. Highly integrated services are agreed to be nonterminable. With respect to “nonterminable” services that Dow has agreed to provide to us, such as electricity and steam, we generally cannot terminate such services prior to the termination date unless we experience a production unit shut down for which we provide Dow with 15-months prior notice, or upon payment of a shutdown fee. Upon expiration or termination, we would be obligated to pay a monthly fee to Dow, which obligation extends for a period of 45 (in the case of expiration) to 60 months (in the case of termination) following the respective event of each site services agreement. The agreements under which Dow receives services from us may be terminated under the same circumstances and conditions.

24

For the years ended December 31, 2015, 2014, and 2013, we incurred a total of $244.8 million, $285.2 million, and $306.2 million in expenses under the SAR MOSA, AR MOD5 Agreement, and site services agreements (which include utilities), including $194.1 million, $233.7 million, and $235.1 million, respectively, for both the variable and fixed cost components of the site service agreements and $50.7 million, $51.5 million, $71.1 million, respectively, covering all other agreements.

In addition, upon Acquisition, we entered into two contract manufacturing agreements pursuant to which Dow operates and maintains one of its facilities to produce polycarbonate products for us in Freeport, Texas, and we operate and maintain our SAN facility in Midland, Michigan to produce products for Dow, each for an initial term of up to 25 years from the Acquisition date. These agreements generally have 25-year terms, with automatic renewals for five-year terms unless one party gives notice at least 18 months prior to the end of the period. We may terminate any operational service under the agreements in the event that we experience a production unit shutdown, with 15-months prior notice to Dow, and Dow may terminate the supply of operational services to us in the event of Dow’s permanent cessation of the operation, also with 15-months prior notice. Furthermore, the agreements may be terminated by mutual agreement between the parties, by either party on notice that the other party fails to cure non-performance or if the other party is in material breach of a material obligation under the agreement within certain parameters, or because of either party’s insolvency.

During the second quarter of 2014, the Company announced a restructuring within its Basic Plastics & Feedstocks segment to exit the commodity market for polycarbonate in North America and to terminate existing arrangements with Dow regarding manufacturing services for the Company at Dow’s Freeport, Texas facility (the “Freeport facility”). The Company also entered into a new long-term supply contract with a third party to supply polycarbonate in North America. These revised arrangements became operational in the fourth quarter of 2014. Production at the Freeport facility ceased as of September 30, 2014, and decommissioning and demolition began thereafter, with completion in the first quarter of 2015. The Company incurred $7 million in expenses reimbursing Dow for its decommissioning and demolition of this facility.  In addition, the Company executed revised supply contracts for certain raw materials that were processed at its polycarbonate manufacturing facility in Stade, Germany, which took effect January 1, 2015. These revised agreements facilitated improvements in future results of operations for the Basic Plastics & Feedstocks segment.

We have also entered into certain license agreements pursuant to which we have obtained exclusive licenses to use certain of Dow’s intellectual property in connection with the Styron business as it was conducted by Dow and non-exclusive licenses to use certain Dow intellectual property, other than patents, with respect to products outside of the Styron business as it was conducted by Dow prior to the Acquisition, subject to certain limitations. While our license rights are sufficient to allow us to operate our current business, new growth opportunities in latex and, to a lesser extent, plastics involving new products may fall outside of our license rights with Dow. Therefore, our ability to develop new products may be adversely impacted by intellectual property rights that have been retained by Dow.

We have entered into long-term supply agreements whereby Dow supplies ethylene, benzene, butadiene, Bisphenol A, or BPA, and other raw materials amounting to approximately 29% of our raw materials (based on aggregate purchase price). The ethylene, benzene and butadiene agreements are each for an initial term of up to 10 years from the closing date of the Acquisition. Our BPA supply agreement with Dow expires in December 2019. These agreements do not contain any specific termination provisions and pricing is generally based on certain standard industry markers with appropriate volume discounts some of which can be negotiated from time to time.

For the years ended December 31, 2015, 2014, and 2013, purchases and other charges from Dow and its affiliated companies (excluding the SAR MOSA, AR MOD5 Agreement, and site services agreements) were approximately $999.4 million, $1,910.8 million, and $2,030.3 million, respectively. For the years ended December 31, 2015, 2014, and 2013, sales to Dow and its affiliated companies were approximately $227.0 million, $343.8 million, and $294.7 million, respectively.

We continue to leverage Dow’s scale and operational capabilities by procuring certain raw materials, utilities, site services, and other information technology and business services from Dow. In connection with the Acquisition, we entered into several agreements with Dow relating to the provision of certain products and services and other operational arrangements. Dow provides significant operating and other services, and certain raw materials used in the production of our products, under agreements that are important to our business. The failure of Dow to perform their obligations, or the termination of these agreements, could adversely affect our operations. See Item 1A—Risk Factors.

Joint Venture Option Agreement

In connection with the Acquisition in 2010, certain of our affiliates entered into the Latex JV Option Agreement with Dow, pursuant to which Dow was granted an irrevocable option to purchase 50% of the issued and outstanding interests in a joint venture to be formed by Dow and our affiliates with respect to the SB latex business in Asia, Latin America, the Middle East, Africa, Eastern Europe, Russia and India. On May 30, 2014, our affiliates entered into an agreement with Dow to terminate the Latex JV Option Agreement, Dow’s previous exercise of their option rights, and all other obligations thereunder, in exchange for a termination payment of $32.5 million. This termination payment was made on May 30, 2014, and the termination of the Latex JV Option Agreement became effective as of such date.

Our Joint Ventures

To supplement our business segments, we entered into two strategic joint ventures in order to gain access to local markets, minimize costs and accelerate growth in areas we believe have significant business potential.

Americas Styrenics

Launched in 2008, Americas Styrenics is a 50% / 50% joint venture between us and Chevron Phillips Chemical Company. Under the terms of the joint venture agreement, Americas Styrenics has the exclusive rights to manufacture and sell polystyrene in North America and South America, and produces a range of HIPS and GPPS products. We believe the venture has capitalized on the strong relationships and technology leadership of its parent companies to maintain a strong industry presence and pursue developing opportunities. Americas Styrenics has benefitted from industry consolidation and the cyclical recovery in the North American styrenics market.

Sumika Styron Polycarbonate

Sumika Styron Polycarbonate is a 50% / 50% venture with Sumitomo Chemical of Japan. Sumika Styron Polycarbonate has exclusive rights in Japan to manufacture and sell a range of our PC products and facilitates our access to the Japanese PC market. Sumika Styron Polycarbonate’s facility is located in an integrated and efficient manufacturing site, and uses Dow technology and production processes.

Sources and Availability of Raw Materials

Our raw materials group is responsible for the ongoing sourcing and procurement of raw materials for each of our business segments. The professionals leading this group have extensive experience in the petrochemical industry buying, selling, and swapping commodity raw materials. Our raw materials group seeks to implement the most efficient and reliable raw material strategy for our business segments, including maintaining a balance between contracted and spot purchases.  We also produce raw materials for use by our businesses, such as styrene monomer. While Dow provides a significant portion of our raw materials to us pursuant to supply agreements, including ethylene, benzene, butadiene and BPA, we have developed a comprehensive strategy for obtaining additional sources of supply where needed. Our agreements with Dow range from 1- to 10-year terms with, in some cases, an automatic 2-year renewal. Minimum and maximum monthly contract quantities were established based on historical consumption rates, and our pricing terms are based on commodity indices in the relevant geography. We obtained approximately 31% of our raw materials from Dow in 2015 (based on aggregate purchase price).

The prices of key raw materials that we purchase, including benzene, ethylene, styrene, butadiene and BPA, are volatile and can fluctuate significantly from time to time. The predominant drivers of this volatility are the prices of crude oil and natural gas as well as the impact of market imbalances in supply and demand from time to time. We have supply contracts in place to help maintain our supply of raw materials at competitive market prices.

Styrene

In addition to purchasing styrene through long-term strategic contracts and spot market purchases, we produce styrene internally from purchased ethylene and benzene at our own manufacturing sites. These sources provided 40%, 19%, and 41%, respectively, of our supply in 2015. With this mix of purchased and produced styrene, we seek to

26

optimize our overall costs of securing styrene through efficient logistics, manufacturing economics and market dynamics.

We believe the low steam-to-oil ratios (“S/O”) of our styrene production plants make them highly energy efficient as compared to other players in our industry. This technology also uses proprietary catalyst technology that supports operation in low S/O conditions and enables long runs between turnarounds. In addition, the styrene production process leverages in-house computational fluid dynamic and reaction models to predict catalyst activity over time, at varying operating conditions, to optimize run rates.

Benzene and Ethylene

Benzene and ethylene are two commodity petrochemicals that represent the majority of the raw materials needed for styrene production. In 2015, Dow supplied us with approximately 96% of our benzene requirements and 100% of our ethylene requirements through 10-year contracts that commenced in 2010 and include automatic 2-year renewal provisions. The volume of benzene that we purchase from Dow may vary quarterly based on our needs at the time. Our operations that use benzene and ethylene are connected to Dow’s cracker operations where these raw materials are produced by a supply pipeline that facilitates the efficient delivery of our raw material requirements. We monitor these materials and how changes in their costs impact the styrene supply chain and its downstream derivatives. Our pricing formulae with Dow are based on well-known indices for the region and generally include large buyer discounts.

Butadiene

Butadiene is an important raw material for the Synthetic Rubber and Latex segments. Dow is our largest supplier for this material in Europe where we purchase directly from Dow’s existing butadiene extraction facilities pursuant to the terms of a 10-year contract that commenced in 2010 and includes an automatic 2-year renewal term. Other supply sources in Europe include major producers with contract terms of up to five years at competitive market prices. Supply to North America and Asia are exclusively from other major third party producers via supply contracts. As a large purchaser of butadiene, we believe we can continue to secure the raw material reliably at competitive prices.

Bisphenol A

BPA is the major raw material associated with PC production. This raw material is produced by a subsidiary of Olin Corporation and is supplied via pipeline to us through a supply contract in Europe that has an initial term expiring in December 2019. We source BPA for our North American operations and Asian joint ventures from other market participants. We no longer have a need for BPA in North America as of 2015.

Manufacturing

Our Latex segment had 30 production units that are strategically located throughout the world. We believe these facilities have industry leading quality tracking.

We manufacture all synthetic rubber products at one integrated site at Schkopau, Germany. We believe that our synthetic rubber plant compares favorably to average benchmarks across key cost metrics and is one of the more cost-efficient synthetic rubber production sites in Europe.

Our Performance Plastics segment operates on a global basis with compounding operations in Stade, Germany; Terneuzen, The Netherlands; and Hsinchu, Taiwan. We also have strategic compounding agreements in Asia, North America and Europe.

We operate our Basic Plastics & Feedstocks segment on a global basis, including plants in China, our integrated Schkopau, Germany site, and our PC site in Stade, Germany, in close proximity to faster growing regions. We believe that our polystyrene plants compare favorably to benchmarks across key cost metrics. Additionally, we believe our joint venture with Chevron Phillips Chemical Company LP, Americas Styrenics, is well-positioned to serve North America and emerging opportunities in South America. We manufacture SAN for Dow under an agreement in our Midland, Michigan facility. We also believe our strategic joint venture with Sumitomo Chemical of Japan, Sumika Styron Polycarbonate, enables us to gain access to an expanded range of geographies and customers.

27

Technology

Our R&D and TS&D activities across our segments focus on identifying needs in our customers’ end-markets. As part of our customer-centric model, our R&D/TS&D organization interfaces with our sales and marketing teams and directly with customers to determine their product requirements in light of trends in their industries and market segments. This information is used to select R&D/TS&D projects that are value-enhancing for both our customers and us. Our R&D/TS&D activities and capabilities include:

· formulation knowledge, which enables accelerated new product development;

· internal capabilities, such as latex pilot coaters and plastics mini plants;

· functionalization technology, which is a key capability in our synthetic rubber products to enable us to continue to develop new grades for tire products;

· compounding expertise, which comprises knowledge of the compounding process coupled with formulation knowledge and facilitates our ability to develop new compounds and blends to meet evolving needs in various businesses; and

· providing a broad product portfolio with innovative solutions to meet customer needs.

Our R&D facilities support our technological capabilities. In addition to our two SB latex pilot coaters and our product development centers, our Plastics and Emulsion Polymers business units operate “mini plants” in Stade and Schkopau, Germany. These mini plants are used to make samples of experimental products for testing, which we believe is a critical step in our new product development process.

R&D and TS&D costs are included in expenses as incurred. Our R&D and TS&D costs were $51.9 million, $53.4 million, and $49.7 million for the years ended December 31, 2015, 2014, and 2013, respectively.

Sales and Marketing

We have a customer-centric business model that has helped us to develop strong relationships with many customers. Including periods prior to the Acquisition when our predecessor business was operated by Dow, we have an average length of key customer relationships exceeding 20 years. Our application development, R&D, TS&D, marketing and sales functions work together to define the customers’ needs and develop technologically differentiated solutions that create value for both the customer and us and result in greater customer intimacy. This can be seen most clearly in competitive applications such as coated paper and packaging board, automotive, consumer electronics, and glazing and construction sheet.

Our sales and marketing teams play a key role in realizing this strategy around technologically differentiated solutions. Our sales and marketing initiatives include:

· Developing a solution-centric approach to sales versus a product-centric approach. Our sales and marketing teams understand the trends in the industries and applications served by us, and this is critical to identifying changing customer requirements and providing differentiated value-added products.

· Coordinating account teams effectively to develop and implement customer solutions. We often include sales-people and TS&D engineers in customer activities. Where appropriate, we involve our engineers to develop new applications and respond to fast moving market trends.

· Understanding the value chain and effectively deploying our resources across this chain. In some of our end-markets, our immediate customers may be distributors or manufacturers, rather than the original equipment manufacturers. In these instances, our sales and marketing teams may employ a multi-channel marketing approach, developing relationships with the key decision makers across the value chain to develop differentiated, value-added products. For example, our automotive business markets its products: (1) through distributors, (2) directly to a broad range of small, medium and large parts suppliers, and (3) directly to the auto manufacturers themselves.

Our sales and marketing professionals are primarily located at our facilities or at virtual offices within their respective geographies. We have approximately 127 professionals working in sales and marketing around the world, along with approximately 71 customer service professionals and we sell our products to customers in over 82 countries.

28

We primarily market our products through our direct sales force. All of our direct sales are made by our employees in the regions closest to the given customer. Historically, we have focused the majority of our direct sales efforts on large customers and relied on large distributors for sales to smaller accounts. In addition to the key initiatives outlined above, we intend to increase the amount of customers we serve directly.

Information Systems

We use Dow’s Enterprise Resource Planning (“ERP”) software systems to support our operations worldwide. We have the right to use Dow’s ERP software applications and infrastructure under the terms of the SAR MOSA and its related functional statements of work. The SAR MOSA has a current term that expires on December 31, 2020. Under the terms of the SAR MOSA, Dow extends its work processes and the supporting applications and infrastructure for us to use. Under the SAR MOSA, Dow’s work process expertise centers provide the knowledge-base and documentation required for our personnel to follow work process steps and procedures.

We also use Dow’s global data/voice network and server infrastructure for desktop computing, email, file sharing, intranet and internet website access, mainframe and midrange computer access and voice communications. Business software applications are included in the work processes supported under the SAR MOSA. These applications complement a number of our other global ERP applications to provide us with the equivalent of a modern ERP landscape. We use the various ERP applications to manage our day-to-day business processes and relationships with customers and suppliers. In 2015, we embarked on a joint project with Dow to upgrade our legacy ERP environment to the latest version of SAP over the next two years.

Our manufacturing plants use Dow-developed proprietary process control/process automation technology under the AR MOD5 Agreement. We are licensed to use this technology and receive support and spare parts through the expiration of the current term of the agreement on December 31, 2020. While we are not permitted to use this automation technology for new plants or to substantially expand existing plants, we can use other technology solutions for those situations. We are migrating our manufacturing plants off of the AR MOD5 technology to a substitute third-party process control technology from ABB Ltd, a leading supplier of advanced process control systems. For more information on the AR MOD5 Agreement, see —“Our Relationship with Dow”.

Intellectual Property

We evaluate on a case-by-case basis how best to utilize patents, trademarks, copyrights, trade secrets and other intellectual property in order to protect our products and our critical investments in research and development, manufacturing and marketing. We focus on securing and maintaining patents for certain inventions, while maintaining other inventions as trade secrets, derived from our customer-centric business model, in an effort to maximize the value of our product portfolio and manufacturing capabilities. Our policy is to seek appropriate protection for significant product and process developments in the major markets where the relevant products are manufactured or sold. Patents may cover products, processes, intermediate products and product uses. Patents extend for varying periods in accordance with the date of patent application filing and the legal life of patents in the various countries. The protection afforded, which may also vary from country to country, depends upon the type of subject matter covered by the patent and the scope of the claims of the patent.

In most industrial countries, patent protection may be available for new substances and formulations, as well as for unique applications and production processes. However, given the geographical scope of our business and our continued growth strategy, there are regions of the world in which we do business or may do business in the future where intellectual property protection may be limited and difficult to enforce. We maintain strict information security policies and procedures wherever we do business. These information security policies and procedures include data encryption, controls over the disclosure and safekeeping of confidential information, as well as employee awareness training. Moreover, we monitor our competitors’ products and, if circumstances were to dictate that we do so, we would vigorously challenge the actions of others that conflict with our patents, trademarks and other intellectual property rights.

The technologies we utilize in some of our business lines have been in use for many years (e.g., SB latex and ABS) and a number of our patents relating to such technologies have expired or will expire in within the next several years. As patents expire, or are allowed to lapse, the products and processes described and claimed in those patents become generally available for use by the public. We believe that the expiration of any single patent or family of patents

29

that is scheduled to expire in the next 3 years would not materially adversely affect our business or financial results. We believe that our trade secrets relating to manufacturing and other processes used in connection with products to which expiring patents relate will continue to provide us with a competitive advantage after the expiration of these patents.

We use trademarks as a means of differentiating our products. We protect our trademarks against infringement where we deem appropriate. In the first quarter of 2015, we completed a rebranding process to change our operating name and legal entities from “Styron” to “Trinseo.”  In support of this rebranding process, we have successfully registered the TRINSEO™ trademark in over 90 countries and have other trademark applications pending.

Dow has either transferred to us or granted perpetual, royalty-free licenses to us to use Dow’s intellectual property that was used by Dow to operate the Styron business prior to the Acquisition. These intellectual property includes certain processes, compositions and apparatus used in the manufacture of our products. In addition to our license rights to use Dow’s intellectual property related to the Styron business, we have obtained licenses to use Dow’s intellectual property to the extent necessary to perform our obligations under the contracts transferred to us in the Acquisition and to use such intellectual property (other than patents) for products outside of the Styron business as it was conducted by Dow prior to the Acquisition, subject to certain limitations. While we believe our license rights with respect to Dow’s intellectual property are sufficient to allow us to operate our current business, new growth opportunities in latex and, to a lesser extent, plastics involving new products may fall outside of our license rights with Dow. Therefore, our ability to develop new products may be impacted by intellectual property rights that have not been licensed to us by Dow. We have the right, with Dow’s cooperation, to directly enforce the patents that are exclusively licensed to us by Dow where infringement is primarily within the scope of our business but nothing obligates Dow to enforce against third parties the intellectual property rights of Dow that are licensed to us on a non-exclusive basis or where the infringement is primarily outside the scope of our business.

Since our formation on June 17, 2010, we have focused our product innovation on the Performance Materials division, including the Synthetic Rubber, Latex and Performance Plastics segments. The intellectual property that we have created since we were a wholly-owned subsidiary of Dow is largely in these segments and covers areas such as material formulations, material process technologies and various end-use industrial applications.

Environmental and Other Regulations

Obtaining, producing and distributing many of our products involve the use, storage, transportation and disposal of toxic and hazardous materials. We are subject to extensive, evolving and increasingly stringent national and local environmental laws and regulations, which address, among other things, the following:

· emissions to the air;

· discharges to soils and surface and subsurface waters;

· other releases into the environment;

· prevention, remediation or abatement of releases of hazardous materials into the indoor or outdoor environment;

· generation, handling, storage, transportation, treatment and disposal of waste materials;

· maintenance of safe conditions in the workplace;

· registration and evaluation of chemicals;

· production, handling, labeling or use of chemicals used or produced by us; and

· stewardship of products after manufacture.

Some of our products are also subject to food contact regulations.

We maintain policies and procedures to monitor and control environmental, health and safety risks, and to monitor compliance with applicable state, national, and international environmental, health and safety requirements. In 2015, we issued a Supplier Code of Conduct, which includes our expectations for our suppliers to comply with applicable laws and regulations and encourages them to adhere to the highest principles of environmental responsibility.  We have a strong environmental, health and safety organization. Our environmental, health and safety compliance and management programs benefit from access to certain of Dow’s programs. We are also committed to the American Chemistry Council Responsible Care® Guiding Principles for our global facilities and received third party certification of our Responsible Care® Management System in 2013. We have a staff of professionals who are responsible for environmental health,

30

safety and product regulatory compliance. Additionally, we have services agreements with Dow to provide environmental, health and safety services for certain of our facilities. We have implemented a corporate audit program for all of our facilities. However, we cannot provide assurance that we will at all times be in full compliance with all applicable environmental laws and regulations. We expect that stringent environmental regulations will continue to be imposed on us and our industry in general.

In 2011, the National Toxicology Program, or NTP, classified styrene as “reasonably anticipated to be a human carcinogen”. The classification, confirmed by the National Academy of Sciences, did not take into consideration recent occupational studies of long-term exposures to styrene monomer, which have found no link between styrene and cancer or other serious conditions in humans. The classification did not change how our products are regulated or handled by our customers. Styrene monomer is considered to have low toxicity and is not classified as a carcinogen or mutagen in the EU Nations. We have not seen a significant shift in customer demand away from styrenics products due to this NTP classification. We believe that there are no simple substitutes for our products that can deliver the same performance, quality, safety and cost effectiveness as the current set of products our customers buy from us.  Nevertheless, in March 2015, the California Office of Environmental Health Hazard Assessment, or OHEA, published a notice of intent to list styrene monomer as “known to the state to cause cancer” in humans.  A decision on the listing is not anticipated in the near term.

There has been controversy for a number of years regarding the safety of BPA. A 2012 French ban on food packaging containing BPA was challenged with limited success, although legal proceedings related to this matter still continue. In January 2013, the California OHEA provided notice of proposed rulemaking to adopt a Proposition 65 Maximum Allowable Dose Level of 290 micrograms per day for exposures to BPA based upon authoritative bodies listing mechanism “as known to cause reproductive toxicity.” One of our trade associations, the American Chemistry Council, filed a lawsuit seeking to enjoin the listing, which was ultimately denied and an appeal is pending. In May 2015, the California OHEA listed BPA as a reproductive toxicant under its expert body listing mechanism, which will go into effect later this year, unless an appeal is filed.  However, even if the listings stand, the levels of BPA in our products are well below this Maximum Allowable Dose Level, and we do not expect this listing will have a material impact on our products or manufacturing operations. Additionally, the U.S. Food and Drug Administration has reaffirmed its view, based on its most recent safety assessment, that BPA is safe at the current levels occurring in foods. Also, in January 2015, the European Food Safety Authority (EFSA) issued its long-awaited scientific opinion on the safety of BPA for consumers. EFSA’s expert Panel on Food Contact Materials, Enzymes, Flavourings and Process Aids (CEF) had decided that the publication of new scientific research on BPA in recent years called for a re-evaluation of the chemical. In summary, EFSA concluded “No consumer health risk from Bisphenol A exposure.” EFSA’s comprehensive assessment considered all age groups and examined food and other potential exposure sources.

We have actively responded through direct communication to our customers and employees to address perceptions and concerns regarding the safety and environmental impact of our products. Our industry trade associations, the Styrene Information and Research Center and the American Chemistry Council, as well as many of our customers are also active through political advocacy, media relations, legal action, and scientific and regulatory activities.

Similarly, we remain active in our trade associations, which are engaged to respond to potential health concerns involving BPA, Styrene and other chemicals used in our manufacturing processes.

Sustainability and Climate Change

Our July 2015 Sustainability and Corporate Social Responsibility Report, which is available on our website, provides our most recent sustainability highlights for our products, performance and operations. The report also profiles how our products help our customers improve their own sustainability in areas such as LED lighting, green tires, building insulation, smart meters, life-saving medical devices, and lighter weight vehicles. Also in this report, we noted that 4% of the Company’s global electricity consumption is derived from renewable energy sources, and that, overall, the Company has reduced its energy use by 2% from the prior year.

Chemical Registration

The goal of the U.S. Toxic Substances Control Act (“TSCA”) is to prevent unreasonable risks of injury to health or the environment associated with the manufacture, processing, distribution in commerce, use, or disposal of chemical substances. Under the TSCA, the Environmental Protection Agency has established reporting, record-keeping, testing

31

and control-related requirements for new and existing chemicals. During the past several years, efforts have been underway to reform the TSCA and various legislative initiatives have been introduced most recently the Safe Chemicals Act of 2013 and the Chemical Safety Improvement Act. We actively monitor the progress of these and other legislative developments, and anticipate TSCA reforms this year.

Registration, Evaluation, and Authorization of Chemicals (“REACH”) is the regulatory system for chemicals management in the EU. It requires EU manufacturers and importers to disclose information on the properties of their substances that meet certain volume or toxicological criteria and register the information in a central database to be maintained by the European Chemicals Agency. We have completed the REACH requirements for registration of high-volume and high-hazard substances that we manufacture in or import into Europe and we are currently on track to complete the remaining implementation requirements by the deadline in 2018. Other jurisdictions have enacted legislation similar to REACH, including China, Japan and Korea. We do not expect that the costs to comply with REACH and similar requirements will be material to our operations and consolidated financial position. We currently do not expect to need to register additional chemicals under REACH until 2018, at which time we will be required to register our low volume chemicals.

Environmental Proceedings

Prior to our separation from Dow, the EPA conducted a multimedia investigation at Dow’s Midland, Michigan sites, including the ABS site that we now operate. The investigation uncovered a number of alleged violations, including of the Clean Air Act’s leak detection and repair program (“LDAR”). LDAR requires chemical and petroleum companies to control fugitive (i.e., non-point source) emissions of hazardous air pollutants that occur from valves, pumps, flanges, connectors and other piping components. We, Dow and the United States executed a consent decree, which was approved by the District Court in Michigan in 2011. The decree provides that Dow will implement an enhanced LDAR program at our ABS facility over a five year period, which is intended to further reduce fugitive emissions at the ABS facility. We are not a defendant in the action, but under the decree, we or any future owner of the affected equipment will be responsible for performing an enhanced LDAR program at the ABS facility should Dow fail to perform. Dow’s failure to perform would subject it to significant stipulated penalties. An implementation agreement has been negotiated between us and Dow, which provides that Dow will bear the costs of the enhanced LDAR program.

Environmental Remediation

Environmental laws and regulations require mitigation or remediation of the effects of the disposal or release of chemical substances. Under some of these regulations, as the current owner or operator of a property, we could be held liable for the costs of removal or remediation of hazardous substances on or under the property, without regard to whether we knew of or caused the contamination, and regardless of whether the practices that resulted in the contamination were permitted at the time they occurred. At our Allyn’s Point, Connecticut property we lease a portion of the property to our joint venture, Americas Styrenics, for its operations, which includes a regulated hazardous waste boiler. Potential liabilities resulting from our owner status are addressed through financial assurance mechanisms and other agreements. Many of our production sites have an extended history of industrial use, and it is impossible to predict precisely what effect these laws and regulations will have on us in the future. Soil and groundwater contamination has occurred at some of the sites, and might occur or be discovered at other sites. Subject to certain monetary and temporal limitations, Dow is obligated to indemnify and hold us harmless with respect to releases of hazardous material that existed at our sites prior to our separation from Dow in June 2010. However, we cannot be certain that Dow will fully honor the indemnity or that the indemnity will be sufficient to satisfy all claims that we may incur. In addition, we face the risk that future claims might fall outside of the scope of the indemnity, particularly if we experience a release of hazardous materials that occurs in the future or at any time after our separation from Dow. Except for minor monitoring activities that we are performing in Livorno, Italy pursuant to an agreement with Dow, we do not currently have any material obligations to perform environmental remediation on our properties, and any active remedial projects on our properties are being performed by Dow pursuant to its indemnification obligations or for any Superfund sites.

Environmental Programs

We have comprehensive environmental, health and safety compliance, auditing and management programs in place to assist in our compliance with applicable regulatory requirements and with internal policies and procedures, as appropriate. We use Dow’s environmental health and safety programs, including a management system, as a cornerstone

32

of our programs and have contracts in place with Dow for the use of their environmental, health and safety expertise. Each facility has developed and implemented specific critical occupational health, safety, environmental, security and loss control programs. We participate in the chemical industry’s Responsible Care® initiative and have implemented a number of environmental and quality management systems at our facilities. In addition to Responsible Care® Management System certification, the majority of our sites have received ISO 14001 environmental management system certifications. Additionally, our German facilities have received ISO 50001 energy management system certifications.

We have a Board of Directors’ Committee on Environmental Health and Safety and Public Policy. We also have implemented an environmental, health and safety (“EH&S”) organizational structure with executive committee level leadership and dedicated environmental experts. We have an EH&S leader at each of our manufacturing sites who is responsible for environmental, health and safety matters at that site. We also have corporate, regional and facility EH&S leaders, as well as a Product Stewardship Organization that manages day-to-day EH&S issues related to our products and customers. Our Process Safety Organization is dedicated to reducing and eliminating process safety incidents.

Facility Security

We recognize the importance of security and safety to our employees and the community. Physical security measures have been combined with process safety measures (including the use of technology), and emergency response preparedness into integrated security plans. We have conducted vulnerability assessments at our operating facilities in the U.S. and high priority sites worldwide and identified and implemented appropriate measures to protect these facilities from physical and cyber-attacks. Effort and resources in assessing security vulnerabilities and taking steps to reinforce security at our manufacturing facilities will continue to be required to comply with U.S. Department of Homeland Security (“DHS”) and other requirements.

Employees

As of December 31, 2015, we had 2,270 employees worldwide. Nearly 83% of our personnel are located at the various manufacturing sites, research and development, pilot coating, paper fabrication and testing and technology centers. The remaining employees are located at operating centers, virtual locations or geographically dispersed marketing and sales locations. Our Midland, Michigan site is the only U.S. facility with union representation for its approximately 55 hourly operations personnel, and employees at certain of our locations are represented by work councils. We consider relations with our personnel and the various labor organizations to be good. There have been no labor strikes or work stoppages in these locations in recent history.

Item 1A.    Risk Factors

Risks Related to Our Business

Our current level of indebtedness of our subsidiaries could adversely affect our financial condition.

As of December 31, 2015, our indebtedness totaled approximately $1,207.8 million.  This amount included our $300.0 million USD Notes and €375.0 million Euro Notes issued by our subsidiaries.  This amount also included our $496.4 million 2021 Term Loan B issued on May 5, 2015, when our subsidiaries entered into our Senior Credit Facility. 

33

The Senior Credit Facility also includes our 2020 Revolving Facility. As of December 31, 2015, we had no borrowings and had $311.5 million (net of $13.5 million outstanding letters of credit) of funds available for borrowings under the 2020 Revolving Facility.  Several of our subsidiaries are also party to our Accounts Receivable Securitization Facility, for up to a total of $200.0 million in borrowings. As of December 31, 2015, there were no amounts outstanding, with approximately $123.4 million of funds available for borrowing under this facility, based on the pool of eligible accounts receivable. We are also a party to a short-term revolving credit facility through our subsidiary in China that provides uncommitted funds available for borrowing, subject to the availability of collateral.  We had no outstanding borrowings under this revolving credit facility as of December 31, 2015.

Our level of indebtedness could have important consequences, including:

· increasing our vulnerability to economic downturns and adverse industry conditions;

· compromising our flexibility to capitalize on business opportunities and to react to competitive pressures, as compared to our competitors;

· placing us at a disadvantage compared to other, less leveraged competitors or competitors with comparable debt at more favorable interest rates; and

· increasing our cost of borrowing.

In addition, a substantial portion of our subsidiaries current indebtedness is secured by substantially all of our assets, which may make it more difficult to secure additional borrowings at reasonable costs. If we default or declare bankruptcy, after these obligations are met, there may not be sufficient funds or assets to satisfy our subordinate interests, including those of our shareholders.

The terms of our subsidiaries’ indebtedness may restrict our current and future operations, particularly our ability to respond to change or to take certain actions. 

The Indenture and the credit agreement governing the Borrowers’ Senior Credit Facility contain a number of covenants imposing certain restrictions on our subsidiaries’ businesses. These restrictions may affect our ability to operate our business and may limit our ability to take advantage of business opportunities. These agreements restrict, among other things, our subsidiaries’ ability to:

· sell assets;

· incur additional indebtedness;

· pay dividends to Trinseo S.A.;

· make investments or acquisitions;

· incur liens;

· repurchase or redeem capital stock;

· engage in mergers or consolidations;

· materially alter the business they conduct;

· engage in transactions with affiliates; and

· consolidate, merge or transfer all or substantially all of their assets.

The ability of our subsidiaries to comply with the covenants and financial ratios and tests contained in the Indenture and Credit Agreement, to pay interest on indebtedness, fund working capital, and make anticipated capital expenditures depends on our future performance, which is subject to general economic conditions and other factors, some of which are beyond our control. There can be no assurance that our business will generate sufficient cash flow from operations or that future borrowings will be available under our Senior Credit Facility to fund liquidity needs in an amount sufficient to enable them to service their indebtedness. Furthermore, if we need additional capital for general corporate purposes or to execute on an expansion strategy, there can be no assurance that this capital will be available on satisfactory terms or at all.

A failure to repay amounts owed under the 2020 Revolving Facility or 2022 Senior Notes at maturity would result in a default. In addition, a breach of any of the covenants in the 2020 Revolving Facility or Indenture governing our 2022 Senior Notes or our inability to comply with the required financial ratios or limits could result in a default. If a default occurs, lenders may refuse to lend us additional funds and the lenders or noteholders could declare all of the debt and any accrued interest and fees immediately due and payable. A default under one of our subsidiaries debt agreements may

34

trigger a cross-default under our other debt agreements.  For more information regarding our indebtedness and liquidity, please see Item 7—Management’s Discussion and Analysis of Financial Conditions and Results of Operations—  Indebtedness and Liquidity.

To service our subsidiaries’ indebtedness, we will require a significant amount of cash. If we are unable to execute on our business strategy and generate significant cash flow, we may be unable to service our indebtedness and repay in full the notes at maturity. 

To service their indebtedness, our subsidiaries will require a significant amount of cash. Our ability to generate cash flow and service these debt obligations will depend upon, among other things, our future financial condition and operating performance. These factors depend partly on economic, financial, competitive conditions and on certain financial, business, legislative, regulatory and other factors beyond our control. We may not be able to generate sufficient cash from operations to meet our debt service obligations as well as fund necessary capital expenditures.

If our cash flows and capital resources are insufficient to fund these debt service obligations, we could face substantial liquidity problems and could be forced to reduce or delay investments and capital expenditures or to dispose of material assets or operations, seek additional debt or equity capital or restructure or refinance our subsidiaries’ indebtedness. We may not be able to affect any such alternative measures on commercially reasonable terms or at all, and, even if successful, those alternative actions may not allow our subsidiaries to meet their scheduled debt service obligations. The Senior Credit Facility and the Indenture governing our 2022 Senior Notes restrict the ability of our subsidiaries to dispose of assets and the use of proceeds from those dispositions and may also restrict our ability to raise debt or equity capital to be used to repay other indebtedness when it becomes due. Therefore, our subsidiaries may not be able to consummate those dispositions or to obtain proceeds in an amount sufficient to meet any debt service obligations then due.

Despite our subsidiaries’ current levels of indebtedness, we may incur substantially more debt, which could further exacerbate the risks associated with our indebtedness.

Although the Senior Credit Facility and the indenture governing our 2022 Senior Notes contain restrictions on the incurrence of additional indebtedness, these restrictions are subject to a number of qualifications and exceptions and the indebtedness incurred in compliance with these restrictions could be substantial. Also, we are not prevented from incurring obligations that do not constitute “indebtedness” as defined in the Senior Credit Facility or the Indenture, such as operating leases and trade payables. If new debt is added to our subsidiaries’ current debt levels, the risks related to indebtedness that we now face could intensify.

Our joint ventures may not operate according to their business plans if we or our partners fail to fulfill our or their obligations, or differences in views among our joint venture partners result in delayed decisions, which may adversely affect our results of operations and may force us to dedicate additional resources to these joint ventures.

We currently participate in two joint ventures and may enter into additional joint ventures in the future. The nature of a joint venture requires us to share control with unaffiliated third parties. If our joint venture partners do not fulfill their obligations, the affected joint venture may not be able to operate according to its business plan. In that case, our results of operations may be adversely affected and we may be required to increase the level of our commitment to the joint venture.

Differences in views among joint venture participants and our inability to unilaterally implement sales and productions strategies or determine cash distributions from our joint ventures may significantly impact short-term and longer term financial results, financial condition and the value of our ordinary shares.

Regulatory and statutory changes applicable to our raw materials and products and our customers’ products could require material expenditures, changes in our operations and could adversely affect our financial condition and results of operations.

Changes in environmental, health and safety regulations, in jurisdictions where we manufacture and sell our products, could lead to a decrease in demand for our products. In addition to changes in regulations, health and safety concerns could increase the costs incurred by our customers to use our products and otherwise limit the use of these

35

products, which could lead to decreased demand for these products. Such a decrease in demand likely would have an adverse effect on our business and results of operations. Materials such as acrylonitrile, ethylbenzene, styrene, butadiene, BPA and halogenated flame retardant are used in the manufacturing of our products and have come under scrutiny due to potentially significant or perceived health and safety concerns.

The federal Toxic Substances Control Act, or the TSCA, is the primary law in the U.S. governing the manufacture, processing, use and distribution of our chemicals. Among other things, under the TSCA, the EPA has the authority to (i) require testing of chemicals that may present an unreasonable risk of injury to health or the environment or are produced in substantial quantities, (ii) undertake pre-market review of, and impose restrictions as appropriate on, new chemicals prior to their commercial production and introduction into the marketplace, (iii) limit or prohibit the manufacture, use, distribution and disposal of existing substances, (iv) impose reporting and record keeping requirements to ensure continued access to new information on chemical substances, and (v) oversee export and import notice requirements. Other chemical control regimes continue to be enacted. The European Union’s REACH was followed by the enactment of similar chemical control laws in countries such as China, Japan, and Korea. These regulatory regimes currently require significant compliance expenditures by us, and changes applicable to our raw materials and products or our customers’ products could require significant additional expenditures by us, or changes in our operations.

Our products are also used in a variety of end-uses that have specific regulatory requirements such as those relating to products that have contact with food or medical device end-uses. We and many of the applications for the products in the end markets in which we sell our products are regulated by various national and local rules, laws and regulations, such as the TSCA. Changes in regulations could result in additional compliance costs, seizures, confiscations, recall or monetary fines, any of which could prevent or inhibit the development, distribution and sale of our products. Changes in environmental and safety laws and regulations banning or restricting the use of these residual materials in our products, or our customers’ products, could adversely affect our results of operations and financial condition. Failure to appropriately manage safety, human health, product liability and environmental risks associated with our products, product life cycles and production processes could adversely impact employees, communities, stakeholders, our reputation and the results of our operations.

We may be subject to losses due to liabilities or lawsuits related to contaminated land we own or operate or arising out of environmental damage or personal injuries associated with exposure to chemicals or the release of chemicals.

The Comprehensive Environmental Response, Compensation and Liability Act, or CERCLA, and analogous state and foreign laws are designed to address the problems associated with contaminated land, especially inactive and abandoned hazardous waste sites listed on the “National Priorities List”, or NPL. Under CERCLA and similar statutes, the current or former owner or operator of a property contaminated by hazardous substance releases is subject to strict, unlimited, joint, several and retroactive liability for the investigation and remediation of the property, and also may be liable for natural resource damages associated with the releases. We also face the risk that individuals could seek damages for personal injury due to exposure to chemicals at our facilities, chemicals which have been released from our facilities, chemicals otherwise owned or controlled by us, or chemicals which allegedly migrated from products containing our materials. Legal claims and regulatory actions could subject us to both civil and criminal penalties, which could affect our product sales, reputation and profitability.

There are several properties which we now own on which Dow has been conducting remediation to address historical contamination. Those properties include Allyn’s Point, Connecticut; Dalton, Georgia; Livorno, Italy; and Guaruja, Brazil. There are other properties with historical contamination that are owned by Dow that we lease for our operations, including our facility in Midland, Michigan. While we did not assume the liabilities associated with these properties in the U.S., because CERCLA and similar laws can impose liability for contamination on the current owner or operator of a property, even if it did not create the contamination, there is a possibility that a governmental authority or private party could seek to include us in an action or claim for remediation or damages, even though the contamination may have occurred prior to our ownership or occupancy. While Dow has agreed to indemnify us for liability for releases of hazardous materials that occurred prior to our separation from Dow, the indemnity is subject to monetary and temporal limitations, and we cannot be certain that Dow will fully honor the indemnity or that the indemnity will be sufficient to satisfy all claims that we may incur. In addition, we face the risk that future claims might fall partially or fully outside of the scope of the indemnity, particularly if there is a release of hazardous materials that occurs in the

36

future or at any time after the closing of the Acquisition or if the condition requiring remediation is attributable to a combination of events or operations occurring prior to and after the closing of the Acquisition.

The environmental liabilities at a particular site could increase as a result of, among other things, changes in laws and regulations, modifications to the site’s investigation and remediation plans, unanticipated construction problems, identification of additional areas or quantities of contamination, increases in labor, equipment and technology costs, significant changes in the financial condition of Dow or other responsible parties and the outcome of any related legal and administrative proceedings to which we may become a party. Any increase in liability may be outside the scope of the indemnity provided by Dow, resulting in increased costs payable by us. It is not possible for us to reasonably estimate the amount and timing of all future expenditures related to environmental or other contingent matters. Accruals for environmental matters are recorded by us when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based on current law and existing technologies.

Risks are inherent in the chemical business, particularly risks associated with safety, health and the environment. The U.S. Environmental Protection Agency’s (“EPA”) Risk Management Program (“RMP”) requires facilities that produce, handle, process, distribute or store certain highly hazardous chemicals to develop a risk management plan and program in the event of an accidental release of such chemicals. RMP also requires facilities to assess potential impacts to off-site populations in the event of a credible worst-case release and to document the policies, procedures, equipment and work practices in place to mitigate identified risks. Similar risk management requirements are imposed under the Emergency Planning and Community Right-to-Know Act, which contains chemical emergency response planning, accident release and other reporting and notification requirements applicable to our facility. In addition, we are subject to the Occupational Safety and Health Administration Process Safety Management standard, which requires the development of a program to manage workplace risks associated with highly hazardous chemicals. Similar laws apply to many of our international facilities. Failure to comply with such laws could subject us to both civil and criminal penalties, which could affect our product sales, reputation and profitability. We may be subject to claims with respect to workplace exposure, workers’ compensation and other health and safety matters.

Volatility in the cost of the raw materials utilized for our products or disruption in the supply of the raw materials may adversely affect our financial condition and results of operations.

Our results of operations can be directly affected positively and negatively by volatility in the cost of our raw materials, which are subject to global supply and demand and other factors beyond our control. Our principal raw materials (benzene, ethylene, butadiene, BPA and styrene) together represent approximately 56% of our total cost of goods sold. Volatility in the cost of these raw materials makes it more challenging to manage pricing and pass the increases on to our customers in a timely manner. We believe that rapid changes in pricing also can affect the volume our customers consume. As a result, our gross profit and margins could be adversely affected.

Styrene, a principal raw material purchased and produced by us, is used in the production of polystyrene, ABS, SAN, SB latex and our rubber products and, like its principal raw materials, ethylene and benzene, is subject to a volatile market. The wider the styrene to benzene and ethylene spread, with styrene more than benzene and ethylene, the more profitable it is to produce styrene.

Crude oil prices also impact our raw material costs. Generally, higher crude oil prices lead to higher costs of raw materials, although some raw materials are impacted less than others.

Market volatility also impacts our accounting for our inventories. We use either our cost to us or market price, whichever is lower, with cost being determined on the first-in, first-out (“FIFO”) method. As a result, in periods of rapidly declining cost of inventories, the FIFO impact on our reported earnings may be negative. Similarly, in periods of rapidly increasing cost of inventories, the effects of the FIFO method could skew our results of operations, causing them to appear more positive than the actual results.

If the availability of any of our principal raw materials is limited, we may be unable to produce some of our products in the quantities demanded by our customers, which could have an adverse effect on plant utilization and our sales of products requiring such raw materials.

Butadiene prices may be and in the past have been highly volatile. In some cases, market participants have had difficulty securing their supply. While butadiene supply over the past year has not been limited, this trend could reverse with increases in rubber demand.

37

Suppliers may have temporary limitations preventing them from meeting our butadiene requirements, and we may not be able to obtain substitute supplies of butadiene from alternative suppliers in a timely manner or on favorable terms. The quantity of butadiene available in any one region is dependent on the raw material inputs and operating rates of the ethylene crackers. Raw material inputs to the crackers (either ethane or naphtha) depend on the flexibility of the cracker to use various feeds and the economics of the available raw materials.

In June 2010, we entered into long-term supply agreements (10 years) with Dow for critical raw materials ethylene, benzene, and butadiene. A five-year BPA contract has been extended until 2020. These raw materials and other less critical materials amount to approximately 29% of our raw materials (based on aggregate purchase price). The remainder is purchased via other third-party suppliers on a global basis. As our Dow contracts and other third-party contracts expire, we may be unable to renew these contracts or obtain new long-term supply agreements on terms comparable or favorable to us, depending on market conditions, which may significantly impact our operations.

In addition, many of our long-term contracts contain provisions that allow our suppliers to limit the amount of raw materials shipped to us below the contracted amount in force majeure circumstances. If we are required to obtain alternate sources for raw materials because Dow or any other supplier is unwilling or unable to perform under raw material supply agreements or if a supplier terminates its agreements with us, we may not be able to obtain these raw materials from alternative suppliers in a timely manner or be able to enter into long-term supply agreements on terms comparable or favorable to us.

Dow provides significant operating and other services, and certain raw materials used in the production of our products, under agreements that are important to our business. The failure of Dow to perform its obligations, or the termination of these agreements, could adversely affect our operations.

Prior to June 17, 2010, we were operated by Dow, which has provided and continues to provide services under certain agreements that are important to our business. For the years ended December 31, 2015, 2014, and 2013, purchases from and other charges paid to Dow and its affiliated companies (excluding those under the SAR MOSA AR MOD5 Agreement, and site services agreements) were approximately $999.4 million, $1,910.8 million,  and $2,030.3 million, respectively. For the years ended December 31, 2015, 2014, and 2013, sales to Dow and its affiliated companies were approximately $227.0 million, $343.8 million, and $294.7 million, respectively. For the years ended December 31, 2015, 2014, and 2013, we incurred expenses totaling $244.8 million, $285.2 million, and $306.2 million, respectively, under the SAR MOSA, AR MOD5 Agreement, and site services agreements (which include utilities), including $194.1 million, $233.7 million, and $235.1 million, respectively, for both the variable and fixed cost components of the site service agreements and $50.7 million, $51.5 million, $71.1 million, respectively, covering all other agreements.

We are a party to:

· an outsourcing service agreement pursuant to which Dow provides certain administrative and business services to us for our operations;

· supply and sales agreements pursuant to which Dow, among other things, provides us with raw materials, including ethylene, benzene, butadiene and BPA; and

· an operating services agreement pursuant to which Dow will operate and maintain certain of our facilities at Rheinmunster, Germany as well as employ and provide almost all of the staff for this facility.

Under the terms of the above agreements, either party is permitted to terminate the applicable agreement in a variety of situations, including in the event of the other party’s uncured material breach, insolvency, change of control or cessation of operations. Should Dow fail to provide these services or raw materials, or should any of the above agreements be terminated, we would be forced to obtain these services and raw materials from third parties or provide them ourselves. Additionally, if Dow terminates agreements pursuant to which we are obligated to provide certain services, we may lose the fees received by us under these agreements. The failure of Dow to perform its obligations under, or the termination of, any of these contracts could adversely affect our operations and, depending on market conditions at the time of any such termination, we may not be able to enter into substitute arrangements in a timely manner, or on terms as favorable to us.

38

We are party to certain license agreements with Dow relating to intellectual property that is essential to our business. Because of this relationship, we may have limited ability to expand our use of certain intellectual property beyond the field of the license or to police infringement that may be harmful to our business.

In connection with the Acquisition, we acquired ownership of, or in some cases, a worldwide right and license to use, certain patents, patent applications and other intellectual property of Dow that were used by Dow to operate our business segments or held by Dow primarily for the benefit of our business segments, prior to the Acquisition. Generally, we acquired ownership of the intellectual property that was primarily used in our business segments and acquired a license to a more limited set of intellectual property that had broader application within Dow beyond our core business segments. Our license from Dow is perpetual, irrevocable, fully paid, and royalty-free. Furthermore, our license from Dow is exclusive within our business segments for certain patents and patent applications that were used by Dow primarily in the Styron business prior to the Acquisition, subject to licenses previously granted by Dow, and to certain retained rights of Dow, including Dow’s retained right to use patents and patent applications outside of our business segments and for internal consumption by Dow. Our license from Dow relates to polymeric compositions, manufacturing processes and end applications for the polymeric compositions; and is limited to use in defined areas corresponding to our current business segments excluding certain products and end-use application technology retained by Dow. Our ability to develop, manufacture or sell products and technology outside of these defined areas may be impeded by the intellectual property rights that have been retained by Dow, which could adversely affect our business, financial condition and results of operations. Additionally, we may not be able to enforce, and Dow may be unwilling to enforce, this intellectual property that has been retained by Dow where infringement could also impact our business and competitive position.

Hazards associated with chemical manufacturing could adversely affect our operations.

Due to the nature of our business, we are exposed to the hazards associated with chemical manufacturing and the related storage and transportation of raw materials, products and wastes. These hazards could lead to an interruption or suspension of operations and have an adverse effect on the productivity and profitability of a particular manufacturing facility or on us as a whole. Potential hazards include the following: piping or storage tank leaks and ruptures; mechanical failures; employee exposure to hazardous substances; and chemical spills and other discharges or releases of toxic or hazardous substances or gases. There is also a risk that one or more of our key raw materials or one or more of our products may be found to have currently unrecognized toxicological or health-related impact on the environment or on our customers or employees. These hazards may cause personal injury and loss of life, damage to property and contamination of the environment, which could lead to government fines or work stoppage injunctions and lawsuits by injured persons. If such actions are determined to be adverse to us, we may have inadequate insurance to cover such claims, or we may have insufficient cash flow to pay for such claims. Such an outcome could adversely affect our financial condition and results of operations.

Our end markets are highly competitive, and we may lose market share to other producers or to producers of other products that can be substituted for our products.

Our industry is highly competitive and we face significant competition from large international producers, as well as from smaller regional competitors. Competition is based on a number of factors, such as product quality, service and price. Our competitors may improve their competitive position in our core end-use markets by successfully introducing new products, improving their manufacturing processes or expanding their capacity or manufacturing facilities. Additionally, increases in the costs of our primary raw materials, such as butadiene and styrene, could allow our competitors to offer products made from more cost effective chemistries. Some of our competitors may be able to drive down prices for our products if their costs are lower than our costs. Some of our competitors’ financial, technological and other resources may be greater than our resources and such competitors may be better able to withstand changes in market condition. Our competitors may be able to respond more quickly than we can to new or emerging technologies or changes in customer requirements. If we are unable to keep pace with our competitors’ product and manufacturing process innovations, our financial condition and results of operations could be materially adversely affected.

In addition, consolidation of our competitors or customers may result in reduced demand for our products or make it more difficult for us to compete with our competitors. If we are unable to successfully compete with other producers of our products or if other products can be successfully substituted for our products, our sales may decline.

39

Compliance with extensive and evolving environmental, health and safety laws may require substantial expenditures.

We use large quantities of hazardous substances, generate hazardous wastes and emit wastewater and air pollutants in our manufacturing operations. Consequently, our operations are subject to extensive environmental, health and safety laws and regulations at both the national and local level in multiple jurisdictions. Many of these laws and regulations have become more stringent over time and the costs of compliance with these requirements may increase, including costs associated with any capital investments for pollution control facilities. In addition, our production facilities require operating permits that are subject to periodic renewal and, in circumstances of noncompliance, may be subject to revocation. The necessary permits may not be issued or continue in effect, and any issued permits may contain more stringent limitations that restrict our operations or that require further expenditures to meet the permit requirements.

This continuing focus on climate change in jurisdictions in which we operate could result in new, potentially diverging or inconsistent, environmental regulations that may negatively affect us. Additional future regulation of greenhouse gases in the U.S. could occur pursuant to future international treaty obligations, regulatory changes under the federal Clean Air Act or other existing legislation, federal, state or regional adoption of greenhouse gas regulatory schemes, or any combination of the foregoing or otherwise. This could cause us to incur additional costs in complying with any new regulations, which may adversely impact our operations and financial condition.

Compliance with more stringent environmental requirements would likely increase our costs of transportation and storage of raw materials and finished products, as well as the costs of storage and disposal of wastes. Additionally, we may incur substantial costs, including penalties, fines, damages, criminal or civil sanctions and remediation costs, or experience interruptions in our operations for failure to comply with these laws or permit requirements.

Conditions in the global economy and capital markets may adversely affect our results of operations, financial condition and cash flows.

Our products are sold in markets that are sensitive to changes in general economic conditions, such as sales of automotive and construction products. Downturns in general economic conditions can cause fluctuations in demand for our products, product prices, volumes and margins. A decline in the demand for our products or a shift to lower-margin products due to deteriorating economic conditions could adversely affect sales of our products and our profitability and could also result in impairments of certain of our assets.

Our business and operating results were severely affected by the global recession beginning in 2008. We continue to be impacted by turbulence in the credit markets, dislocations in the housing and commercial real estate markets, fluctuating commodity prices, volatile exchange rates and other challenges currently affecting the global economy and our customers. Instability in financial and commodity markets throughout the world has caused, among other things, severely diminished liquidity and credit availability, rating downgrades of certain investments and declining valuations and pricing volatility of others, volatile energy and raw materials costs, geopolitical issues and failure and the potential failure of major financial institutions. In addition, the ongoing sovereign debt crisis affecting various countries in the European Union is creating further uncertainties in the global credit markets. Deterioration in the financial and credit market heightens the risk of customer bankruptcies and delay in payment. We are unable to predict the duration of the current economic conditions or their effects on financial markets, our business and results of operations. If economic conditions deteriorate, our results of operations, financial condition and cash flows could be materially adversely affected.

40

Production at our manufacturing facilities could be disrupted for a variety of reasons. Disruptions could expose us to significant losses or liabilities.

The hazards and risks of disruption associated with chemical manufacturing and the related storage and transportation of raw materials, products and wastes exist in our operations and the operations of other occupants with whom we share manufacturing sites. These potential risks of disruption include, but are not necessarily limited to:

· pipeline and storage tank leaks and ruptures;

· explosions and fires;

· inclement weather and natural disasters;

· terrorist attacks;

· failure of mechanical, process safety and pollution control equipment;

· chemical spills and other discharge or releases of toxic or hazardous substance or gases; and

· exposure to toxic chemicals.

These hazards could expose employees, customers, the community and others to toxic chemicals and other hazards, contaminate the environment, damage property, result in personal injury or death, lead to an interruption or suspension of operations, damage our reputation and adversely affect the productivity and profitability of a particular manufacturing facility or us as a whole, and result in the need for remediation, governmental enforcement, regulatory shutdowns, the imposition of government fines and penalties and claims brought by governmental entities or third parties. Legal claims and regulatory actions could subject us to both civil and criminal penalties, which could affect our product sales, reputation and profitability. Although we have environmental, health and safety compliance and management systems to reduce potential risks and emergency response and crisis management plans in place, these systems and plans may not address or foresee all potential risks or causes of disruption.

If disruptions occur, alternative facilities with sufficient capacity or capabilities may not be available, may cost substantially more or may take a significant time to start production. Each of these scenarios could negatively affect our business and financial performance. If one of our key manufacturing facilities is unable to produce our products for an extended period of time, our sales may be reduced by the shortfall caused by the disruption and we may not be able to meet our customers’ needs, which could cause them to seek other suppliers. Furthermore, to the extent a production disruption occurs at a manufacturing facility that has been operating at or near full capacity, the resulting shortage of our product could be particularly harmful because production at the manufacturing facility may not be able to reach levels achieved prior to the disruption.

Although we maintain property, business interruption, comprehensive general liability, environmental impairment liability and other insurance of the types and in the amounts that we believe are customary for the industry, we may not be fully insured against all potential causes of disruption due to limitations and exclusions in our policies. While the hazards associated with chemical manufacturing have not resulted in incidents that have significantly disrupted our operations or exposed us to significant losses or liabilities since the Acquisition, there can be no assurances we will not suffer such losses in the future.

We could be subject to changes in our tax rates and the adoption of tax legislation or exposure to additional tax liabilities that may adversely affect our results of operations.

We are subject to taxes in Luxembourg, the U.S., and numerous other foreign jurisdictions where our subsidiaries are organized. Due to economic and political conditions, tax rates in various jurisdictions may be subject to significant change. Our future effective tax rates could be affected by changes in the mix of earnings in countries with differing statutory tax rates, changes in the valuation of deferred tax assets and liabilities, and changes in tax laws or their interpretation, such as interpretations as to the legality of tax advantages granted under the European Union ("EU") state aid rules. Our tax returns and other tax matters are subject to examination by local tax authorities and governmental bodies. We regularly assess the likelihood of an adverse outcome resulting from these examinations to determine the adequacy of our provision for taxes. There can be no assurance as to the outcome of these examinations. If our effective tax rates were to increase, or if the ultimate determination of the taxes owed by us is for an amount in excess of amounts previously accrued, our operating results, cash flows, and financial condition could be adversely affected.

41

Any increase in the cost of natural gas or electricity may adversely affect our results of operations.

We use natural gas and electricity to operate our facilities and generate heat and steam for our various manufacturing processes. Natural gas prices have experienced significant volatility in the past several years. Wide fluctuations in natural gas prices may result from relatively minor changes in supply and demand, market uncertainty, and other factors, both domestic and foreign, that are beyond our control. In addition, natural gas is often a substitute for petroleum-based energy supplies. Future increases in the price of petroleum (resulting from increased demand, political instability or other factors) may result in significant additional increases in the price of natural gas. In addition, electricity prices are generally affected by increases in the price of petroleum. Any increase in the cost of natural gas or electricity could have a material adverse impact on our financial condition and results of operations.

There is no assurance that we will be able to renew all necessary licenses, certificates, approvals and permits for our operations.

Our operation is subject to various licenses, certificates, approvals and permits in different foreign jurisdictions. There is no assurance that we will be able to renew our licenses, certificates, approvals and permits upon their expiration. The eligibility criteria for such license, certificates, approvals and permits may change from time to time and may become more stringent. In addition, new requirements for licenses, certificates, approvals and permits may come into effect in the future. The introduction of any new and/or more stringent laws, regulation, licenses, certificates, approvals and permits requirements relevant to our business operations may significantly escalate our compliance and maintenance costs or may preclude us to continue with our existing operations or may limit or prohibit us from expanding our business. Any such event may have an adverse effect to our business, financial results and future prospects.

If we fail to maintain an effective system of internal control, we may not be able to accurately report our financial results or prevent fraud.

Effective internal controls are necessary to provide reliable financial reports and to assist in the effective prevention of fraud. Any inability by us to provide reliable financial reports or prevent fraud could harm our business. We must annually evaluate its internal procedures to satisfy the requirements of Section 404 of the Sarbanes-Oxley Act of 2002, which requires management and auditors to assess the effectiveness of internal controls. If we fail to remedy or maintain the adequacy of its internal controls, as such standards are modified, supplemented or amended from time to time, we could be subject to regulatory scrutiny, civil or criminal penalties or shareholder litigation.

In addition, failure to maintain adequate internal controls could result in financial statements that do not accurately reflect our financial condition. There can be no assurance that we will be able to complete the work necessary to fully comply with the requirements of the Sarbanes-Oxley Act or that our management and external auditors will continue to conclude that the Company's internal controls are effective.

Our business involves risk of exposure to product liability claims.

Even though we are generally a materials supplier rather than a manufacturer of finished goods, the development, manufacture and sales of specialty emulsion polymers and plastics by us involve inherent risks of exposure to product liability claims, product recalls and related adverse publicity. While we attempt to protect ourselves from such claims and exposures by our adherence to standards and specifications and in our contractual negotiations, there can be no assurance that our efforts in this regard will ultimately protect us from any such claims. For instance, a customer may attempt to seek contribution from us due to a product liability claim brought against them by a consumer, or a consumer may bring a product liability claim directly against us. A product liability claim or judgment against us could result in substantial and unexpected expenditures, affect consumer or customer confidence in our products, and divert management’s attention from other responsibilities. A successful product liability claim or series of claims against us in excess of our insurance coverage payments, for which we are not otherwise indemnified, could have a material adverse effect on our financial condition or results of operations.

The insurance that we maintain may not fully cover all potential exposures.

We maintain insurance typical of similarly situated companies in our industry but such insurance may not cover all risks associated with the operation of our business or our manufacturing process and the related use, storage and transportation of raw materials, products and wastes in or from our manufacturing sites or our distribution centers. While

42

we have purchased what we deem to be adequate limits of coverage and broadly worded policies, our coverage is subject to limitations, including self-insured retentions or deductibles and maximum limits and liabilities covered. Notwithstanding diligent efforts to successfully procure specialty coverage for environmental liability and remediation, we may incur losses beyond the limits or outside the terms of coverage of our insurance policies, including liabilities for environmental remediation. In addition, from time to time, various types of insurance for companies in the specialty chemicals industry have not been available on commercially acceptable terms or, in some cases, at all. We are potentially at additional risk if one or more of our insurance carriers fail. Additionally, severe disruptions in the domestic and global financial markets could adversely impact the ratings and survival of some insurers. Future downgrades in the ratings of enough insurers could adversely impact both the availability of appropriate insurance coverage and its cost. In the future, we may not be able to obtain coverage at current levels, if at all, and our premiums may increase significantly on coverage that we maintain.

We are subject to customs, international trade, export control, antitrust, zoning and occupancy and labor and employment laws that could require us to modify our current business practices and incur increased costs.

We are subject to numerous regulations, including customs and international trade laws, export/import control laws, and associated regulations. These laws and regulations limit the countries in which we can do business; the persons or entities with whom we can do business; the products which we can buy or sell; and the terms under which we can do business, including anti-dumping restrictions. In addition, we are subject to antitrust laws and zoning and occupancy laws that regulate manufacturers generally and/or govern the importation, promotion and sale of our products, the operation of factories and warehouse facilities and our relationship with our customers, suppliers and competitors. If any of these laws or regulations were to change or were violated by our management, employees, suppliers, buying agents or trading companies, the costs of certain goods could increase, or we could experience delays in shipments of our goods, be subject to fines or penalties, or suffer reputational harm, which could reduce demand for our products and hurt our business and negatively impact results of operations. In addition, in some areas we benefit from certain trade protections, including anti-dumping protection and the European Union’s Authorized Economic Operator program, which provides expedited customs treatment for materials crossing national borders. If we were to lose these protections, our results of operations could be adversely affected.

In addition, changes in statutory minimum wage laws and other laws relating to employee benefits could cause us to incur additional wage and benefits costs, which could negatively impact our profitability.

Legal requirements are frequently changed and subject to interpretation, and we are unable to predict the ultimate cost of compliance with these requirements or their effects on our operations. We may be required to make significant expenditures or modify our business practices to comply with existing or future laws and regulations, which may increase our costs and materially limit our ability to operate our business.

We are dependent on the continued service and recruitment of key executives, the loss of any of whom could adversely affect our business.

Our performance is substantially dependent on the performance of our senior management team, including Christopher D. Pappas, our President and Chief Executive Officer, who is also currently acting as our Interim Chief Financial Officer. At this time, we are also actively recruiting for a Chief Financial Officer.  Although we engage in executive succession planning and have entered into agreements with each member of our senior management team that restrict their ability to compete with us should they decide to leave our Company, we cannot be sure that any member of our senior management team will remain with us, or that they will not seek to compete with us in the future. The loss of members of our senior management team or our inability to hire qualified management personnel in a timely manner could impair our ability to execute our business plan and growth strategy, cause us to lose customers and reduce revenue, or lead to employee morale problems and/or the loss of additional key employees.

Fluctuations in currency exchange rates may significantly impact our results of operations and may significantly affect the comparability of our results between financial periods.

Our operations are conducted by subsidiaries in many countries. The results of the operations and the financial position of these subsidiaries are reported in the relevant foreign currencies and then translated into U.S. dollars at the applicable exchange rates for inclusion in our consolidated financial statements. The main currencies to which we are exposed are the euro, the British pound, Chinese renminbi, Indian rupee, Korean won, Brazilian real, and Swedish krona.

43

The exchange rates between these currencies and the U.S. dollar in recent years have fluctuated significantly and may continue to do so in the future. A depreciation of these currencies against the U.S. dollar, in particular the euro, will decrease the U.S. dollar equivalent of the amounts derived from these operations reported in our consolidated financial statements and an appreciation of these currencies will result in a corresponding increase in such amounts. Because some of our raw material costs are procured in U.S. dollars rather than on these currencies, depreciation of these currencies may have an adverse effect on our profit margins or our reported results of operations. Conversely, to the extent that we are required to pay for goods or services in foreign currencies, the appreciation of such currencies against the U.S. dollar will tend to negatively impact our results of operations. In addition, currency fluctuations may affect the comparability of our results of operations between financial periods.

We incur currency translation risk whenever we enter into either a purchase or sale transaction using a currency other than the local currency of the transacting entity.  From time to time, we enter into foreign exchange forward contracts to hedge fluctuations associated with certain monetary assets and liabilities, primarily accounts receivable, accounts payable and certain intercompany obligations.  However, attempts to hedge against foreign currency fluctuation risk may be unsuccessful and result in an adverse impact to our operating results.  Given the volatility of exchange rates, there can be no assurance that we will be able to effectively manage our currency translation risks or that any volatility in currency exchange rates will not have a material adverse effect on our financial condition or results of operations.

We may engage in strategic acquisitions or dispositions of certain assets and/or businesses that could affect our business, results of operations, financial condition and liquidity.

We may selectively pursue complementary acquisitions and joint ventures, each of which inherently involves a number of risks and presents financial, managerial and operational challenges, including:

· potential disruption of our ongoing business and distraction of management;

· difficulty with integration of personnel and financial and other systems;

· hiring additional management and other critical personnel; and

· increasing the scope, geographic diversity and complexity of our operations.

In addition, we may encounter unforeseen obstacles or costs in the integration of acquired businesses. Also, the presence of one or more material liabilities of an acquired company that are unknown to us at the time of acquisition may have a material adverse effect on our business. Our acquisition and joint venture strategy may not be successfully received by customers, and we may not realize any anticipated benefits from acquisitions or joint ventures.

We may also opportunistically pursue dispositions of certain assets and/or businesses, which may involve material amounts of assets or lines of business, and adversely affect our results of operations, financial condition and liquidity. If any such dispositions were to occur, under the terms of the credit agreement governing our Senior Credit Facility and the Indenture, we may be required to apply the proceeds of the sale to repay any borrowings under our Senior Credit Facility or our 2022 Senior Notes.

Because our business operations are conducted entirely through our subsidiaries and joint ventures, we are largely dependent on our receipt of distributions and dividends or other payments from our subsidiaries and joint ventures for cash to fund all of our operations and expenses.

Trinseo S.A., and its subsidiaries and the issuers of its outstanding debt, Trinseo Materials Operating S.C.A. and Trinseo Materials Finance, Inc., are each holding companies without business operations. Therefore, our revenues are generated through business conducted through other operating subsidiaries and joint ventures. As a result, our subsidiaries’ ability to service their debt or to make future dividend payments, if any, is largely dependent on the earnings of our operating subsidiaries and joint ventures and the payment of those earnings to them in the form of dividends, loans or advances and through repayment of loans or advances from us. Payments to us by our operating subsidiaries and joint ventures will be contingent upon our subsidiaries’ or joint ventures’ earnings and other business considerations. Furthermore, the Credit Agreement governing our Senior Credit Facility and the Indenture for the 2022 Senior Notes does restrict the ability of our operating subsidiaries to pay dividends or otherwise transfer assets to us. In addition, each of our subsidiaries and joint ventures is a distinct legal entity.  Therefore, there may be significant tax and other legal or regulatory developments in the future that may impact the ability of foreign subsidiaries or joint ventures to continue to remit money to us.

44

Americas Styrenics LLC, which is one of our joint ventures, is among the parties subject to an ongoing government antitrust investigation by the United States Postal Service Office of Inspector General, and the United States Department of Justice, involving the polystyrene market in North America, the results of which could have a material adverse effect on our business, financial condition and results of operations.

In May 2015, Americas Styrenics, our 50%-owned joint venture, received a subpoena from the United States Postal Service Office of Inspector General in coordination with the U.S. Department of Justice (collectively the “Government”) requesting documents regarding its involvement and participation in the market for polystyrene.  The subpoena received by Americas Styrenics does not seek information regarding the market for styrene monomer.  The Government has informed Americas Styrenics that similar subpoenas have been sent to other companies that operate in the polystyrene market.

Under the joint venture agreement, we granted Americas Styrenics the exclusive rights to manufacture and sell polystyrene in North America and South America.  Equity earnings attributable to Americas Styrenics was $135.3 million, $50.3 million, and $39.4 million in 2015, 2014 and 2013, respectively.  We estimate that the contribution to Trinseo’s equity earnings from Americas Styrenics’ polystyrene business was approximately 55% in 2015, approximately 87% in 2014 and approximately 0% in 2013.  This translates to a contribution from Americas Styrenics’ polystyrene business to Trinseo’s Adjusted EBITDA of approximately 15% in 2015, approximately 17% in 2014 and approximately 0% in 2013.

We understand that Americas Styrenics is fully cooperating with the Government’s investigation and has delivered all requested documents in response to the subpoena.  Further, Americas Styrenics has informed us that it has completed its own internal investigation and is unaware of any improper activity.  We have reviewed the substance of Americas Styrenics’ internal investigation and, based on this information, have no reason to believe any improper activity occurred.  Furthermore, we believe that the industry dynamics present in the polystyrene market are consistent with legitimate competitive market activity and not the result of anti-competitive actions or activity. 

Notwithstanding our current understanding of the facts, this matter remains open with the Government and there can be no assurance that other facts will not come to light that result in Americas Styrenics being determined to have violated applicable law.  As a result, we are unable to make any predictions regarding the ultimate outcome of the investigation.  Other than the subpoena, to date there has been no complaint or demand of Americas Styrenics by the Government regarding the matters that are the subject of the investigation.  In addition, to date we have not been served with a subpoena in connection with this ongoing investigation nor have we otherwise been contacted by the Government or other enforcement authorities.  However, there is no assurance that we won’t be served with a subpoena or otherwise become involved in this investigation in the future.

Based on its findings in the investigation, the Government may (i) close the file, (ii) seek a consent decree to remedy issues it believes violate the antitrust laws, or (iii) file suit against Americas Styrenics for violating the antitrust laws, seeking injunctive or monetary relief. If injunctive and/or monetary relief were granted, depending on its scope, it could affect the manner in which Americas Styrenics’ business is operated and potentially force changes to Americas Styrenics’ business practices or operations.  In addition, Americas Styrenics and its executives could be subject to criminal prosecution and if Americas Styrenics is found to have violated one or more laws, it could be subject to a variety of fines, penalties, and related administrative sanctions and private plaintiffs may seek treble damages. Private plaintiffs may emerge and seek recourse against us, merely as a joint venture owner of Americas Styrenics, and if this investigation continues over a long period of time, it could divert the attention of Americas Styrenics and our management from day-to-day operations and impose significant administrative burdens.  Any of these consequences could damage Americas Styrenics’ and our reputation and impair Americas Styrenics’ ability to conduct its business, which could have a material adverse effect on our business, financial condition and results of operations.

We generally do not have long-term contracts with our customers, and the loss of customers could adversely affect our sales and profitability.

With some exceptions, our business is based primarily upon individual sales orders with our customers. As such, our customers could cease buying our products from us at any time, for any reason, with little or no recourse. If multiple customers elected not to purchase products from us, our business prospects, financial condition and results of operations could be adversely affected.

45

We could be subject to damages based on claims brought against us by our customers or lose customers as a result of the failure of our products to meet certain quality specifications.

Our products provide important performance attributes to our customers’ products. If a product fails to perform in a manner consistent with quality specifications, a customer could seek replacement of the product or damages for costs incurred as a result of the product failing to perform as designed and marketed. A successful claim or series of claims against us could cause reputational harm and have a material adverse effect on our financial condition and results of operations and could result in a loss of one or more customers.

If we are not able to continue the technological innovation and successful commercial introduction of new products, our customers may turn to other producers to meet their requirements.

Our industry and the end markets into which we sell our products experience periodic technological changes and ongoing product improvements. Our customers may introduce new generations of their own products or require new technological and increased performance specifications that would require us to develop customized products. Innovation or other changes in our customers’ product performance requirements may also adversely affect the demand for our products. Our future growth will depend on our ability to gauge the direction of the commercial and technological progress in all key end markets, and upon our ability to successfully develop, manufacture and market products in such changing end markets. We need to continue to identify, develop and market innovative products on a timely basis to replace existing products in order to maintain our profit margins and our competitive position. We may not be successful in developing new products and technology that successfully compete with these materials, and our customers may not accept any of our new products. If we fail to keep pace with evolving technological innovations or fail to modify our products in response to our customers’ needs, then our business, financial condition and results of operations could be adversely affected as a result of reduced sales of our products.

Our business relies on intellectual property and other proprietary information and our failure to adequately protect or effectively enforce our rights could harm our competitive advantages with respect to the manufacturing of some of our products.

Our success depends to a significant degree upon our ability to protect, preserve and enforce our intellectual property and other proprietary information of our business. However, we may be unable to prevent third parties from using our intellectual property and other proprietary information without our authorization or independently developing intellectual property and other proprietary information that is similar to or competes with ours, particularly in those countries where the laws do not protect proprietary rights to the same degree as in the United States. Any inability by us to effectively prevent the unauthorized use of our intellectual property and other proprietary information by others could reduce or eliminate any competitive advantage we have developed, cause us to lose sales or otherwise harm our business. If it becomes necessary for us to initiate litigation to protect our proprietary rights, any proceedings could be burdensome and costly, and we may not prevail.

Any patents we own, or that are exclusively licensed to us, that have been issued or may be issued in the future, may not provide us with any competitive advantage and may be challenged by third parties. Our competitors or others also may seek to oppose or challenge the validity of our pending patent applications or issued patents. Our competitors also may attempt to design around our patents or copy or otherwise obtain and use our intellectual property and other proprietary information. Moreover, our competitors may already hold or have applied for patents in the United States or other countries in which we operate that, if enforced following their issuance, could possibly limit our ability to manufacture or sell one or more of our products in the jurisdictions in which such patents are issued. In general, competitors or other parties may, from time to time, assert issued patents or other intellectual property rights against us. If we are legally determined, at some future date, to infringe or violate the intellectual property rights of another party, we may have to pay damages, stop the infringing use, or attempt to obtain a license of such intellectual property from the owner of such intellectual property. With respect to our pending patent applications, we may not be successful in securing patents for the patent claims we are pursuing. Our failure to secure these patents may limit our ability to protect inventions that these applications were intended to cover. In addition, as our patents expire, or are allowed to lapse, in the coming years, we may face increased competition with consequent erosion of profit margins if we are unable to continue to develop innovations for which we are able to secure new patents or we are unable to effectively protect our know how and innovations as trade secrets.

46

It is our policy to enter into confidentiality agreements with our employees and third parties to protect our confidential proprietary manufacturing know how, technological innovations, proprietary business information and other trade secrets, but our confidentiality agreements could be breached and may not prevent our manufacturing know how and other trade secrets from being misappropriated by others. Adequate remedies may not be available in the event of an unauthorized use or disclosure of our trade secrets and manufacturing know how. Violations by others of our confidentiality agreements and the loss of employees who have specialized knowledge and expertise could harm our competitive position and cause our sales and operating results to decline as a result of increased competition. In addition, others may obtain knowledge of our trade secrets through independent development or by legal means of access.

We have registered and applied for registration of certain service marks and trademarks, and will continue to evaluate the registration and maintenance of additional service marks and trademarks. We have registered the trademark TRINSEO™ in countries throughout the world and have adopted this trademark as a “house” brand for all of our products. As a general matter with respect to our trademarks, the applicable governmental authorities may not approve our pending applications. A failure to obtain, or maintain, trademark registrations in the United States and in other countries could limit our ability to protect and enforce our trademarks and impede our marketing efforts in those jurisdictions. Moreover, third parties may seek to oppose our applications or otherwise challenge the resulting registrations. In the event that any of our trademarks are successfully challenged, we could be forced to rebrand our products or lose product differentiations that our use of the trademarks has created in the marketplace, which could result in loss of brand recognition or customer loyalty or goodwill and could require us to devote resources to advertising and marketing new brands and the development of new products.

We may be unable to determine when third parties are using our intellectual property rights without our authorization, particularly our manufacturing processes. In addition, we cannot be certain that any intellectual property rights that we have licensed to third parties are being used only as authorized by the applicable license agreement. The undetected, unremedied, or unauthorized use of our intellectual property rights or the legitimate development or acquisition of intellectual property that is similar to or competes with ours by third parties could reduce or eliminate the competitive advantage we have as a result of our intellectual property, adversely affecting our financial condition and results of operations.

If we fail to adequately protect our intellectual property and other proprietary information, including our processes, apparatuses, technology, trade secrets, trade names and proprietary manufacturing know how, methods and compounds, through obtaining patent protection, securing trademark registrations and securing our trade secrets through the use of confidentiality agreements of appropriate scope and other means, our competitive advantages over other producers could be materially adversely affected. If we determine to take legal action to protect, defend or enforce our intellectual property rights, any suits or proceedings could result in significant costs and diversion of our resources and our management’s attention. We may not prevail in any such suits or proceedings. A failure to protect, defend or enforce our intellectual property rights could have an adverse effect on our financial condition and results of operations.

Our products may infringe the intellectual property rights of others, which may cause us to incur unexpected costs or prevent us from selling our products.

We continually seek to improve our business processes and develop new products and applications. Many of our competitors have a substantial amount of intellectual property that we must continually strive to avoid infringing. Although it is our policy and intention not to infringe valid patents of which we are aware, we cannot provide assurances that our processes and products and other activities do not and will not infringe issued patents (whether present or future) or other intellectual property rights belonging to others, either in the United States. There nonetheless could be third-party patents that cover our products, processes or technologies, and it is possible that we could be liable for infringement of such patents and could be required to take remedial or curative actions to continue our manufacturing and sales activities with respect to one or more products that are found to be infringing. We may also be subject to indemnity claims by our business partners arising out of claims of their alleged infringement of the patents, trademarks and other intellectual property rights of third parties in connection with their use of our products. Intellectual property litigation often is expensive and time-consuming, regardless of the merits of any claim, and our involvement in such litigation could divert our management’s attention from operating our business. If we were to discover that any of our processes, technologies or products infringe on the valid intellectual property rights of others, we might determine to obtain licenses from the owners of these rights or to modify our processes or technologies or re-engineer our products in order to avoid infringement. We may not be able to obtain the necessary licenses on acceptable terms, or at all, or be able

47

to modify our processes or technologies or re-engineer our products in a manner that is successful in avoiding infringement. Moreover, if we are sued for infringement and lose, we could be required to pay substantial damages and/or be enjoined from using or selling the infringing products or technology. Any of the foregoing could cause us to incur significant costs and prevent us from selling our products and could have an adverse effect on our financial condition and results of operations.

Data security breaches could compromise sensitive information related to our business, which could adversely affect our business and our reputation.

Cyberattacks or data security breaches could compromise confidential, business critical information or cause a disruption in our operations. We have attractive information assets, including intellectual property, trade secrets and other sensitive, business critical information. We face an ever growing risk of attack from outside our organization (including attack by organized crime, so-called “hacktivists,” and state-sponsored actors) using sophisticated technical and non-technical methodologies (including social engineering and “spear phishing” attacks). We also face risks from internal threats to information security, such as from negligent or dishonest employees or consultants. A successful cyberattack or other breach of security could result in the loss of critical business information and/or could negatively impact operations, which could have a negative impact on our financial results. Furthermore, in addition to using our own systems and infrastructure, we use information systems and infrastructure operated by third-party service providers, including Dow. If our third-party service providers experience an information security breach, depending on the nature of the breach, it could compromise confidential, business critical information or cause a disruption in our operations.

The labor and employment laws in many jurisdictions in which we operate are more restrictive than in the United States. Additionally, we have unionized employees in the United States who may stage work stoppages. Our relationship with our employees could deteriorate, which could have an adverse effect on our operations.

As a manufacturing company, we rely on our employees and good relations with our employees to produce our products and maintain our production processes and productivity. Approximately 85% of our employees are employed outside of the United States. In certain of those countries, such as the member states of the European Union, labor and employment laws are more restrictive than in the United States. In many jurisdictions, the laws grant significant job protection to employees, which subject us to employment arrangements that are very similar to collective bargaining agreements.

In addition, as of December 31, 2015, approximately 16% of our employees in United States are members of a union and subject to a collective bargaining agreement. We are required to consult with and seek the consent or advice of the unions or works’ councils that represent our employees for certain of our activities. This requirement could have a significant impact on our flexibility in managing costs and responding to market changes. Furthermore, there can be no assurance that we will be able to negotiate labor agreements with our unionized employees in the future on satisfactory terms. If those employees were to engage in a strike, work stoppage or other slowdown, or if any of our other employees were to become unionized, we could experience a significant disruption of our operations or higher ongoing labor costs, which could have a material adverse effect on our financial condition and results of operations.

As a global business, we are exposed to local business risks in different countries, which could have a material adverse effect on our financial condition or results of operations.

We have significant operations in foreign countries, including manufacturing facilities, R&D facilities, sales personnel and customer support operations. As of December 31, 2015, we operated, or others operated on our behalf, 34 manufacturing plants (which include a total of 80 production units) at 26 sites around the world, including in Colombia, Germany, The Netherlands, Belgium, Italy, Finland, Sweden, China, South Korea, Indonesia, Japan and Taiwan, in

48

addition to our operations in the United States. Our offshore operations are subject to risks inherent in doing business in foreign countries, including, but not necessarily limited to:

· new and different legal and regulatory requirements in local jurisdictions;

· uncertainties regarding interpretation and enforcement of laws and regulations;

· variation in political and economic policy of the local governments and social conditions;

· export duties or import quotas;

· domestic and foreign customs and tariffs or other trade barriers;

· potential staffing difficulties and labor disputes;

· managing and obtaining support and distribution for local operations;

· increased costs of transportation or shipping;

· credit risk and financial conditions of local customers and distributors;

· potential difficulties in protecting intellectual property;

· risk of nationalization of private enterprises by foreign governments;

· potential imposition of restrictions on investments;

· potentially adverse tax consequences, including imposition or increase of withholding and other taxes on remittances and other payments by subsidiaries;

· legal restrictions on doing business in or with certain nations, certain parties and/or certain products;

· foreign currency exchange restrictions and fluctuations; and

· local economic, political and social conditions, including the possibility of hyperinflationary conditions and political instability.

We may not be successful in developing and implementing policies and strategies to address the foregoing factors in a timely and effective manner at each location where we do business. Consequently, the occurrence of one or more of the foregoing factors could have a material adverse effect on our international operations or upon our financial condition and results of operations.

Our operations in developing markets could expose us to political, economic and regulatory risks that are greater than those we may face in established markets. Further, our international operations require us to comply with a number of United States and international regulations. For example, we must comply with the Foreign Corrupt Practices Act (“FCPA”) which prohibits companies or their agents and employees from providing anything of value to a foreign official, or agent thereof, for the purposes of influencing any act or decision of these individuals in their official capacity to help obtain or retain business, direct business to any person or corporate entity or obtain any unfair advantage. We operate in some nations that have experienced significant levels of governmental corruption. Any failure by us to ensure that our employees and agents comply with the FCPA and applicable laws and regulations in foreign jurisdictions could result in substantial civil and criminal penalties or restrictions on our ability to conduct business in certain foreign jurisdictions or reputational damage, and our results of operations and financial condition could be materially and adversely affected.  

Our quarterly results of operations are subject to fluctuations due to the seasonality of our business.

Seasonal changes and weather conditions typically affect the construction and building materials end markets. In particular, sales volumes for construction and building materials generally rise in the warmer months and generally decline during the colder months of fall and winter. Abnormally cold or wet seasons may cause reduced purchases from our construction and building materials customers and, therefore, adversely affect our financial results. However, because seasonal weather patterns are difficult to predict, we cannot accurately estimate fluctuations in our quarterly construction and building materials sales in any given year. Because of the seasonality of our business, results for any one quarter are not necessarily indicative of the results that may be achieved for any other quarter or for the full fiscal year.

49

We have unfunded and underfunded pension plan liabilities. We will require current and future operating cash flow to fund these shortfalls. We have no assurance that we will generate sufficient cash flow to satisfy these obligations.

We maintain defined benefit pension plans covering employees who meet age and service requirements. The majority of these plans are located outside the United States. We have minimum funding requirements for these plans, and may elect to make contributions that do not exceed these minimum requirements. Our net pension liability and cost is materially affected by the discount rate used to measure pension obligations, the longevity and actuarial profile of our workforce, the level of plan assets available to fund those obligations and the actual and expected long-term rate of return on plan assets. Significant changes in investment performance or a change in the portfolio mix of invested assets can result in corresponding increases and decreases in the valuation of plan assets, particularly equity securities, or in a change in the expected rate of return on plan assets and could result in a shortfall. In addition, any changes in the discount rate could result in a significant increase or decrease in the valuation of pension obligations, affecting the reported funded status of our pension plans as well as the net periodic pension cost in the following years. Similarly, changes in the expected return on plan assets can result in significant changes in the net periodic pension cost in the following years.

If our goodwill becomes impaired, we may be required to record a significant charge to earnings.

We are required to test goodwill for impairment at least annually or earlier if events or changes in circumstances indicate the carrying value may not be recoverable. As of December 31, 2015, we had recorded a total of $31.1 million of goodwill. An adverse change in economic or market conditions, changes in technology, changes in competitive conditions and customer preferences, particularly if such changes have the effect of changing one of our critical assumptions or estimates made in connection with the impairment testing of goodwill could result in a change to the estimation of fair value that could result in an impairment charge to our goodwill. Any such material charges may negatively impact our operating results.

Our ability to obtain additional capital on commercially reasonable terms may be limited.

Although we believe our cash and cash equivalents, together with cash we expect to generate from operations and availability under our Senior Credit Facility, which includes a new revolving facility, provide adequate resources to fund ongoing operating requirements, we may need to seek additional financing to compete effectively.

If we are unable to obtain capital on commercially reasonable terms, it could:

· reduce funds available to us for purposes such as working capital, capital expenditures, R&D, strategic acquisitions and other general corporate purposes;

· restrict our ability to introduce new products or exploit business opportunities;

· increase our vulnerability to economic downturns and competitive pressures in the markets in which we operate; and

· place us at a competitive disadvantage.

Risks Related to Our Ordinary Shares

We are a “controlled company” within the meaning of the New York Stock Exchange listing rules and, as a result, we qualify for, and will continue to rely on, exemptions from certain corporate governance requirements.

We are a “controlled company” within the meaning of the corporate governance standards of the New York Stock Exchange. Under the New York Stock Exchange rules, a company of which more than 50% of the voting power is held by an individual, group or another company is a “controlled company” and may elect not to comply with certain corporate governance requirements.

As of December 31, 2015, the Company did not have a majority of its board of director consist of independent directors, and our compensation and nominating/corporate governance committees did not consist entirely of independent directors. We intend to continue to utilize some of these exemptions, until we are no longer a controlled

50

company.   Accordingly, you do not have the same protections afforded to shareholders of companies that are subject to all of the corporate governance requirements of the New York Stock Exchange.

As a controlled company our Parent has significant influence over us, which could limit your ability to influence the outcome of key transactions, including a change of control.

As long as our Parent continues to beneficially own more than 50% of the voting power of our ordinary shares, it will be able to direct the election of all of the members of our board of directors and could exercise a controlling influence over our business and affairs, including any determinations with respect to mergers or other business combinations, the acquisition or disposition of assets, the incurrence of indebtedness, the issuance of any additional ordinary shares or other equity securities, the repurchase or redemption of ordinary shares and the payment of dividends. Similarly, our Parent has the power to determine matters submitted to a vote of our shareholders without the consent of our other shareholders, can prevent a change in our control, and can take other actions that might be favorable to it. Even if its ownership falls below 50%, our Parent and its affiliates may continue to be able to strongly influence or effectively control our decisions.

Additionally, certain affiliates of our Parent are in the business of making investments in companies and may acquire and hold interests in businesses that compete directly or indirectly with us. They may also pursue acquisition opportunities that may be complementary to our business, and, as a result, those acquisition opportunities may not be available to us.

We are a Luxembourg company and, as a result, shareholders may have difficulty effecting service of process or litigation against us or our officers and directors and will not have the same protections afforded to shareholders of a company incorporated in Delaware.

We are organized under the laws of the Grand Duchy of Luxembourg. Many of our assets are located outside the United States and some of our directors and officers named in this prospectus reside outside the United States and most of their assets are located outside the United States. As a result, investors may find it more difficult to effect service of process within the United States upon us or these persons or to enforce outside the United States judgments obtained against us or these persons in U.S. courts, including judgments in actions predicated upon the civil liability provisions of the U.S. federal securities laws. Likewise, it may also be difficult for an investor to enforce in U.S. courts judgments obtained against us or these persons in courts located in jurisdictions outside the United States, including actions predicated upon the civil liability provisions of the U.S. federal securities laws. It may also be difficult for an investor to bring an original action in a Luxembourg court predicated upon the civil liability provisions of the U.S. federal securities laws against us or these persons. Luxembourg law does not recognize a shareholder’s right to bring a derivative action on behalf of a company.

Our corporate affairs are governed by our articles of association and by the laws of the Grand Duchy of Luxembourg. The rights of our shareholders and the responsibilities of our directors and officers under Luxembourg law are different from those applicable to a corporation incorporated in Delaware, or any other state of the United States. Luxembourg law and regulations in respect of corporate governance matters might not be as protective of minority shareholders as the General Corporation Law of the State of Delaware or other state corporation laws. Therefore, our shareholders may have more difficulty in protecting their interests in connection with actions taken by our directors and officers or our principal shareholders than they would as shareholders of a Delaware corporation or a corporation incorporated in another state of the United States.

Provisions in our organizational documents and Luxembourg law may deter takeover efforts or other actions, including share repurchases that could be beneficial to shareholder value.

In addition to our Parent’s beneficial ownership of a controlling percentage of our ordinary shares, our articles of association and Luxembourg law contain provisions that could make it harder for a third party to acquire us, even if doing so might be beneficial to our shareholders. These provisions include a staggered board of directors, the ability of the board of directors to approve a merger or other acquisition and to issue additional ordinary shares without shareholder approval that could be used to dilute a potential hostile acquirer. As a result, you may lose your ability to sell your ordinary shares for a price in excess of the prevailing market price due to these protective measures, and efforts by shareholders to change the direction or management of the company may be unsuccessful.

51

Pursuant to Luxembourg corporate law, existing shareholders are generally entitled to preemptive subscription rights in the event of capital increases and issues of shares against cash contributions. However, our board of directors is authorized to waive, limit or suppress such pre-emptive subscription rights until May 13, 2019.  Furthermore, our shareholders may renew, expand or amend this authorization, which could result in the extension of the waiver beyond the initial five year period, at a future general meeting of shareholders.

In addition, our board of directors is authorized to acquire and sell issued ordinary shares subject to certain price and ownership restrictions until May 14, 2019.  At a future general meeting of our shareholders, our shareholders may renew, expand or amend this authorization. These limitations on share repurchases may have the effect of limiting the terms and duration of any potential share repurchase program or other repurchase transaction.

Your percentage ownership in us may be diluted by future equity issuances, which could reduce your influence over matters on which shareholders vote.

Our board of directors has the authority, without action or vote of our shareholders, to issue all or any part of our authorized but unissued ordinary shares, including shares issuable upon the exercise of options. Issuances of ordinary shares would reduce your influence over matters on which our shareholders vote and, in the case of issuances of preferred stock, would likely result in your interest in us being subject to the prior rights of holders of that preferred stock.

Because Luxembourg law places certain restrictions on our ability to pay dividends and make other cash distributions to shareholders, you may not receive any return on investment unless you sell your ordinary shares for a price greater than that which you paid for it.

Under Luxembourg law, cash dividends must be paid from statutory accounting profits and approved by shareholders.  Trinseo S.A. does not have statutory accounting profits as a holding company without operations. Additionally, cash distributions may be made to shareholders through the repayment of shareholder equity.  The board of directors’ authority to make such repayments of equity is subject to shareholder approval.  Equity repayments are utilizing Trinseo S.A.’s distributable reserves, which is generally its statutory share premium less minimum legal reserves.

Even if shareholder approvals are received and statutory requirements are satisfied to pay dividends or make other cash distributions, we may retain future earnings, if any, for future operations, expansion and debt repayment. Any decision to declare and pay dividends or make other distributions to shareholders, including the repayment of shareholder equity, in the future will be made at the discretion of our board of directors and will depend on, among other things, our results of operations, financial condition, cash requirements, contractual restrictions and other factors that our board of directors may deem relevant. Even if the board chooses to pay a dividend or make a cash distribution to shareholders, it does not guarantee it will continue to do so in the future. As a result, you may not receive any return on an investment in our ordinary shares unless you sell our ordinary shares for a price greater than that which you paid for them.

*Shared site with Americas Styrenics. Our Allyn’s Point latex production site was closed at the end of 2015.

**Facility co-located with Dow facilities under ground lease agreements. Plant facilities are owned by us.

+Facility located on property owned by the applicable government.

++Facility located on property under certification with right to build.

We believe that our properties and equipment are generally in good operating condition and are adequate for our present needs. Production capacity at our sites can vary depending upon product mix and operating conditions.

Our global production facilities are certified to ISO 9001 standards. Our manufacturing facilities have established reliability and maintenance programs and leverage production between sites to maximize efficiency.

53

All plants have similar layouts, technology and manufacturing processes, based on the product being manufactured. We believe this global uniformity creates a key competitive advantage for us, and helps lower overall operating costs.

Item 3.    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.

Item 4.    Mine Safety Disclosures

Not applicable.

PART II

Item 5.Market for Registrant’s Common Equity, Related Stockholder Matters, and Issuer Purchases of Equity Securities

Market Information

Our ordinary shares have been listed on the New York Stock Exchange, or NYSE, under the ticker symbol “TSE” since June 12, 2014. Prior to that time there was no public market for our ordinary shares. The closing price of our ordinary shares, as reported by the NYSE, on March 9, 2016 was $34.58. The following table sets forth the high and low sales prices per share of our ordinary shares, as reported by the NYSE, for the full quarterly periods indicated.

	Price Range

(1) Represents period from June 12, 2014, the date of our initial public offering, through the end of the quarter.

Holders

As of March 9, 2016, there were 2 holders of our ordinary shares and approximately 48,777,934 ordinary shares issued and outstanding. By including persons holding shares in broker accounts under street names, however, we estimate we have approximately 4,500 beneficial holders.  

Dividends

In the last two fiscal years we have not declared or paid dividends or other cash distributions on our ordinary shares. Instead, we have retained earnings to fund the development and growth of our business and to repay indebtedness.   Payment of dividends on our ordinary shares is subject to the determination and declaration by our board of directors, and under Luxembourg law the approval of our shareholders. Luxembourg law also limits the amounts that may be distributed to our shareholders.  Under Luxembourg law, cash dividends must be paid from statutory accounting profits and approved by shareholders.  Trinseo S.A. does not have statutory accounting profits as a holding company without operations.

Luxembourg law also permits cash distributions to shareholders through the repayment of shareholder equity.  The amount of this distribution may not cause the annual non-consolidated statutory net assets of Trinseo S.A. to fall below the aggregate of its issued and subscribed share capital and legal reserves. We are considering requesting from our shareholders the authority for our board of directors to make equity repayments at our next annual meeting.  Nevertheless, even if we receive this authorization from our shareholders, it does not require that our board of directors declare and make an equity repayment, or guarantee that they will do so in the future. 

Because we are a holding company, our ability to pay dividends on our ordinary shares is also limited by restrictions on the ability of our subsidiaries to pay dividends or make distributions to us, including restrictions under the terms of the Credit Agreement governing our subsidiaries’ indebtedness. At this time, these restrictions are not material and there is sufficient capacity under existing restricted payment criteria under the Senior Credit Facility and Indenture to meet our anticipated requirements should the Company elect to declare dividends or another cash distribution to

55

shareholders.  Additionally, our subsidiaries are located in a variety of jurisdictions, so we can give no assurances that our subsidiaries will not face future transfer restrictions due to regulatory changes or other reasons beyond our control.

Any future determination to pay dividends or make other distributions to our shareholders will be at the discretion of our board of directors, subject to compliance with covenants in current and future agreements governing our indebtedness and applicable Luxembourg law, and will depend upon our results of operations, financial condition, capital requirements and other factors that our board of directors deems relevant. Further discussion of these restrictions is included in Item 7—Management’s Discussion and Analysis of Financial Conditions and Results of Operations.

Luxembourg Tax Considerations

Tax Regime Applicable to Capital Gains Realized Upon Disposal of Shares

The following is a summary discussion of the material Luxembourg tax considerations of the acquisition, ownership and disposition of your ordinary shares that may be applicable to you. It is not intended to be, nor should it be construed to be, legal or tax advice. This discussion is based on Luxembourg laws and regulations as they stand on the date of this  report and is subject to any change in law or regulations or changes in interpretation or application thereof (and which may possibly have a retroactive effect). Investors should therefore consult their own professional advisers as to the effects of state, local or foreign laws and regulations, including Luxembourg tax law and regulations, to which they may be subject. As used herein, a “Luxembourg individual” means an individual resident in Luxembourg who is subject to personal income tax (impôt sur le revenu) on his or her worldwide income from Luxembourg or foreign sources, and a “Luxembourg corporate holder” means a company (that is, a fully taxable collectivité within the meaning of Article 159 of the Luxembourg Income Tax Law) resident in Luxembourg subject to corporate income tax (impôt sur le revenu des collectivités) on its worldwide income from Luxembourg or foreign sources. For purposes of this discussion, Luxembourg individuals and Luxembourg corporate holders of our ordinary shares are collectively referred to as “Luxembourg Holders.” A “non-Luxembourg Holder” means any investor in our ordinary shares other than a Luxembourg Holder.

Luxembourg individual holders. For Luxembourg individuals holding (together, directly or indirectly, with his or her spouse or civil partner or minor children) 10% or less of the share capital of Trinseo, capital gains will only be taxable if they are realized on a sale of shares, which takes place before their acquisition or within the first six months following their acquisition. The capital gain or liquidation proceeds will be taxed at progressive income tax rates (ranging from 0 to 50.0% in 2015).

57

For Luxembourg individuals holding (together with his/her spouse or civil partner and minor children) directly or indirectly more than 10% of the capital of Trinseo, capital gains will be taxable at a special rate, if the disposal or liquidation takes place:

· within six months from the acquisition, the capital gain or liquidation proceeds will be taxed at progressive income tax rates (ranging from 0 to 40.0%).

· after six months from the acquisition, the capital gain or the liquidation proceeds will be taxed at a reduced tax rate corresponding to half of the investor’s global tax rate and EUR 50,000 (doubled for taxpayers filing jointly) of gains realized over a ten-year period are exempt from taxation.  

Luxembourg corporate holders. Capital gains realized upon the disposal of shares by a Luxembourg corporate holder will in principle be subject to corporate income tax and municipal business tax. The combined applicable rate (including an unemployment fund contribution) is 29.22% for the fiscal year ending 2015 for a Luxembourg corporate holder established in Luxembourg-City. An exemption from such taxes may be available to the Luxembourg corporate holder pursuant to Article 166 of the Luxembourg Income Tax law subject to the fulfillment of the conditions set forth therein. The scope of the capital gains exemption may be limited in the cases provided by the Grand Ducal Decree of December 21, 2001.

Non-Luxembourg Holders

An individual non-Luxembourg Holder of shares will only be subject to Luxembourg taxation on capital gains arising upon disposal of such shares if such holder has (together with his or her spouse or civil partner and underage children) directly or indirectly held more than 10% of the capital of Trinseo, at any time during the five years preceding the disposal, and either (i) such holder has been a resident of Luxembourg for tax purposes for at least 15 years and has become a non-resident within the five years preceding the realization of the gain, subject to any applicable tax treaty, or (ii) the disposal of shares occurs within six months from their acquisition (or prior to their actual acquisition), subject to any applicable tax treaty. If we and a U.S. relevant holder are eligible for the benefits of the Convention Between the Government of the Grand Duchy of Luxembourg and the Government of the United States for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with Respect to Taxes on Income and Capital (the “Luxembourg-U.S. Treaty”), such U.S. relevant holder generally should not be subject to Luxembourg tax on the gain from the disposal of such shares unless such gain is attributable to a permanent establishment of such U.S. relevant holder in Luxembourg. Subject to any restrictions imposed by the substantially and regularly traded clause in the limitation on benefits article of the Luxembourg-U.S. treaty, we expect to be eligible for the benefits of the Luxembourg-U.S. Treaty.

A corporate non-Luxembourg Holder (that is, a collectivité within the meaning of Article 159 of the Luxembourg Income Tax Law), which has a permanent establishment, a permanent representative or fixed place of business in Luxembourg to which shares would be attributable, will bear corporate income tax and municipal business tax on a gain realized on a disposal of such shares as set forth above for a Luxembourg corporate holder. However, gains realized on the sale of the shares may benefit from the full exemption provided for by Article 166 of the Luxembourg Income Tax Law and by the Grand Ducal Decree of December 21, 2001 subject in each case to fulfillment of the conditions set out therein.

A corporate non-Luxembourg Holder, which has a permanent establishment, permanent representative or fixed place of business in Luxembourg to which the shares would be attributable will not be subject to any Luxembourg tax on a gain realized on a disposal of such shares unless such holder holds, directly or through tax transparent entities, more than 10% of the share capital of Trinseo, and the disposal of shares occurs within six months from their acquisition (or prior to their actual acquisition), subject to any applicable tax treaty. If we and a U.S. corporate holder without a permanent establishment in Luxembourg are eligible for the benefits of the Luxembourg-U.S. Treaty, such U.S. corporate holder generally should not be subject to Luxembourg tax on the gain from the disposal of such shares.

Tax Regime Applicable to Distributions

Withholding Tax. Dividend distributions by Trinseo are subject to a withholding tax of 15%. Distributions by the Company sourced from a reduction of capital as defined in Article 97 (3) of the Luxembourg Income Tax Law including, among others, share premium should not be subject to withholding tax provided that such reduction of capital is

58

motivated by serious business reasons as meant in said provision. We or the applicable paying agent will withhold on a distribution if required by applicable law.

Where a withholding needs to be applied, the rate of the withholding tax may be reduced pursuant to the double tax treaty existing between Luxembourg and the country of residence of the relevant holder, subject to the fulfillment of the conditions set forth therein. If we and a U.S. relevant holder are eligible for the benefits of the Luxembourg-U.S. Treaty, the rate of withholding on distributions generally is 15% or 5% if the U.S. relevant holder is a beneficial owner that owns at least 10% of our voting stock.

No withholding tax applies if the distribution is made to (i) a Luxembourg resident corporate holder (that is, a fully taxable collectivité within the meaning of Article 159 of the Luxembourg Income Tax Law), (ii) a corporation which is resident of a Member State of the European Union and is referred to by article 2 of the Council Directive of July 23, 1990 concerning the common fiscal regime applicable to parent and subsidiary companies of different member states (90/435/EEC), (iii) a corporation or a cooperative resident in Norway, Iceland or Liechtenstein and subject to a tax comparable to corporate income tax as provided by Luxembourg Income Tax Law, (iv) a corporation resident in Switzerland which is subject to corporate income tax in Switzerland without benefiting from an exemption, (v) a corporation subject to a tax comparable to corporate income tax as provided by Luxembourg Income Tax Law which is resident in a country that has concluded a tax treaty with Luxembourg and (vi) a Luxembourg permanent establishment of one of the above-mentioned categories, provided each time that at the date of payment, the holder has held or commits itself to continue to hold directly or through a tax transparent vehicle, during an uninterrupted period of at least twelve months, shares representing at least 10% of the share capital of Trinseo or which had an acquisition price of at least EUR 1,200,000.

Equity Repayment.  The repayment of equity, by the Company is not treated as a dividend distribution under Luxembourg law, and therefore is not subject to any withholding tax, provided: (i) the Company has no statutory reserves or profits at the Company level, and (ii) the capital decrease is motivated by sound business reasons. The Company did not have any statutory profits or reserves as of December 31, 2015. In case the Company does not have sound business reasons to provide a repayment of equity, the entire amount repaid will be subject to a 15% withholding tax, unless the conditions for an exemption or a reduction from the withholding tax on dividends set forth above are met.

Luxembourg Holders

Dividend and liquidation proceeds are in principle taxable at the general income tax rates indicated above. A partial dividend exemption may be available to Luxembourg Holders pursuant to Article 115.15a of the Luxembourg Income Tax law or a full dividend exemption may be available to a Luxembourg corporate holder pursuant to Article 166 of the Luxembourg Income Tax law, subject to the fulfillment of the conditions set forth therein.

Non-Luxembourg Holders

Non-Luxembourg holders of the shares who have neither a permanent establishment, permanent representative nor a fixed place of business Luxembourg to which the shares would be attributable are not liable for any Luxembourg tax on dividends paid on the shares, other than a potential withholding tax as described above.

Net Wealth Tax

Luxembourg Holders.

Luxembourg net wealth tax will not be levied on a Luxembourg Holder with respect to the shares held unless the Luxembourg Holder is an entity subject to net wealth tax in Luxembourg.

Net wealth tax is levied annually at the rate of 0.5% on the net wealth of enterprises resident in Luxembourg, as determined for net wealth tax purposes. The shares may be exempt from net wealth tax subject to the conditions set forth by Article 60 of the Law of October 16, 1934 on the valuation of assets (Bewertungsgesetz), as amended.

59

Non-Luxembourg Holders

Luxembourg net wealth tax will not be levied on a non-Luxembourg Holder with respect to the shares held unless the shares are attributable to an enterprise or part thereof which is carried on through a permanent establishment or a permanent representative in Luxembourg.

Stamp and Registration Taxes

No registration tax or stamp duty will be payable by a holder of shares in Luxembourg solely upon the disposal of shares or by sale or exchange.

Item 7.    Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion summarizes the significant factors affecting the operating results, financial condition, liquidity and cash flows of our Company as of and for the periods presented below. The following discussion and analysis should be read in conjunction with Item 6—“Selected Financial Data” and the audited consolidated financial statements and the accompanying notes thereto, included elsewhere within this Annual Report. The statements in this discussion regarding industry outlook, our expectations regarding our future performance, liquidity and capital resources and all other non-historical statements in this discussion are forward-looking statements and are based on the beliefs of our management, as well as assumptions made by, and information currently available to, our management. Actual results could differ materially from those discussed in or implied by forward-looking statements as a result of various factors, including those discussed below and elsewhere within this Annual Report, particularly in Item 1A—“Risk Factors.”

Definitions of capitalized terms not defined herein appear in the notes to our consolidated financial statements.

2015 Highlights

The full year 2015 was excellent for Trinseo, noting record net income of $133.6 million, Adjusted EBITDA of $492.0 million, and Adjusted EBITDA excluding inventory revaluation of $550.3 million.  This included continued strong performance from our Performance Materials division, as well as record results from our Basic Plastics & Feedstocks division.  We continued to focus efforts on investing in growth areas, reducing costs through streamlining of our portfolio and asset footprint, generating cash, and improving our net leverage and reducing interest expense.  Other highlights of 2015 are described below.

New Reporting Segments

Effective January 1, 2015, the Company was reorganized under two new divisions called Performance Materials and Basic Plastics & Feedstocks. The Performance Materials division now includes the following reporting segments: Synthetic Rubber, Latex, and Performance Plastics. The Basic Plastics & Feedstocks division represents a separate segment for financial reporting purposes and includes styrenic polymers, PC, and styrene monomer. In addition, the Basic Plastics & Feedstocks division includes the results of our two 50%-owned joint ventures, Americas Styrenics and Sumika Styron Polycarbonate. This new organizational structure better reflects the nature of the Company by grouping together segments with similar strategies, business drivers and operating characteristics.  For more information about our reporting segments refer to Item 1—Business.

Name Change and Rebranding

In the first quarter of 2015, we completed a rebranding process to change our operating name and legal entities from “Styron” to “Trinseo.” We believe that this new name reflects our breadth as a company with broad global reach and a diverse portfolio of materials and technologies. We believe Trinseo captures our commitment to deliver innovative and sustainable materials that provide value to our customers’ products.

Debt Refinancing

On May 5, 2015, the Issuers executed an indenture pursuant to which it issued $300.0 million aggregate principal amount of 6.750% senior notes due May 1, 2022 and €375.0 million aggregate principal amount of 6.375% senior notes due May 1, 2022. 

Also on May 5, 2015, the Borrowers entered into the Senior Credit Facility, which provides senior secured financing of up to $825.0 million.  This facility provides for senior secured financing consisting of a (i) $325.0 revolving credit facility, with a $25.0 million swingline subfacility and a $35.0 million letter of credit subfacility maturing in May 2020 and (ii) $500.0 million senior secured 2021 Term Loan B. The 2021 Term Loan B bears an interest rate of LIBOR plus 3.25%, subject to a 1.00% LIBOR floor, and was issued at a 0.25% original issue discount.

62

On May 13, 2015, the net proceeds from these borrowings and available cash were used to repay all outstanding indebtedness under the Issuers’ 2019 Senior Notes totaling $1,192.5 million, together with a call premium of $68.6 million and accrued and unpaid interest thereon of $29.6 million.

This new capital structure is expected to reduce the Company’s annual interest expense by approximately $37.0 million.

Allyn’s Point Plant Shutdown

In September 2015, the Company announced its plan to close its Allyn’s Point latex manufacturing facility in Gales Ferry, Connecticut, due to continuing declines in the coated paper industry in North America.  This plan is part of a program to reduce costs in the business by a $5.0 million run rate in 2016. Production at the facility ceased at the end of 2015, followed by decommissioning and demolition expected in 2016.

Leadership Changes

In October 2015, the Company announced that Martin Pugh, Senior Vice President and Business President for Performance Materials, has been named Executive Vice President and Chief Operating Officer of Trinseo effective November 1, 2015. The Company also announced that Tim Stedman will join Trinseo as Senior Vice President and Business President, Basic Plastics and Feedstocks and Hayati Yarkadas will join Trinseo as Senior Vice President and Business President, Performance Materials, both effective November 1, 2015.

Factors Affecting Our Operating Results

The following discussion sets forth certain components of our statements of operations as well as factors that impact those items.

Net sales

We generate revenue from the sale of our products across all major geographic areas. Our net sales include total sales less estimates for returns and price allowances. Price allowances include discounts for prompt payment as well as volume-based incentives.

Our overall net sales are generally impacted by the following factors:

· fluctuations in overall economic activity within the geographic markets in which we operate;

· fluctuations in raw material input costs and our ability to pass those on to customers, including the effects of a generally 30 to 60-day delay (or greater) in changes to our product prices in our Latex segment, Synthetic Rubber segment, Performance Plastics segment and parts of our Basic Plastics & Feedstocks segment following changes to the relevant raw material prices affect our sales margins;

· underlying growth in one or more of our core end markets, either worldwide or in particular geographies in which we operate;

· changes in the level of competition faced by our products, including the substitution by customers of alternative products to ours and the launch of new products by competitors;

· the type of products used within existing customer applications, or the development of new applications requiring products similar to ours;

· the “mix” of products sold, including the proportion of new or improved products and their pricing relative to existing products;

· changes in product sales prices (including volume discounts and cash discounts for prompt payment);

· our ability to successfully develop and launch new products and applications; and

63

· fluctuations in foreign exchange rates.

While the factors described above impact net sales in each of our segments, the impact of these factors can differ for each segment, as described below. For more information about risks relating to our business refer to Item 1A—Risk Factors.  

Cost of sales

Our cost of sales consists principally of the following:

· Production Materials Costs.    The costs of the materials we use in production are the largest element of our overall cost of sales. We seek to use our substantial volumes and global geographic scope to obtain the most favorable terms we can, but our production material costs are affected by global and local market conditions.

· Employee Costs.    These employee costs include the salary costs and benefit charges for employees involved in our manufacturing operations. These costs generally increase on an aggregate basis as production volumes increase, but may decline as a percent of net sales as a result of economies of scale associated with higher production volumes.

· Sustaining Engineering Activity Costs.    These costs relate to modifications of existing products for use by new customers in familiar applications.

· Depreciation and Amortization Expense.    Property, plant, equipment and definite-lived intangible assets are stated at cost and depreciated on a straight-line basis over their estimated useful lives.

· Other.    Our remaining cost of sales consists of:

· customer-related development costs;

· freight costs;

· warehousing expenses;

· purchasing costs; and

· other general manufacturing expenses, such as expenses for utilities and energy consumption.

The main factors that influence our cost of sales as a percent of net sales include:

· changes in the price of raw materials, and timing of corresponding price changes to our customers, which impact our sales margins;

· production volumes;

· the implementation of cost control measures aimed at improving productivity, reductions of fixed production costs, refinements in inventory management and purchasing cost of raw materials; and

· the impact of FIFO method inventory treatment.

Selling, general and administrative expenses

Our selling, general and administrative, or SG&A, expense consists of all expenditures incurred in connection with the sale and marketing of our products, as well as administrative overhead costs, including:

· salary and benefit costs for sales personnel and administrative staff, including stock-based compensation expense. Expenses relating to our sales personnel generally increase or decrease principally with changes in sales volume due to the need to increase or decrease sales personnel to meet changes in demand. Expenses relating to administrative personnel generally do not increase or decrease directly with changes in sales volume;

64

· other administrative expenses, including expenses related to logistics, information systems and legal and accounting services;

· general advertising expenses;

· research and development expenses; and

· other selling expenses, such as expenses incurred in connection with travel and communications.

Changes in SG&A expense as a percent of net sales have historically been impacted by a number of factors, including:

· changes in sales volume, as higher volumes enable us to spread the fixed portion of our administrative expense over higher sales;

· changes in the mix of products we sell, as some products may require more customer support and sales effort than others;

· changes in our customer base, as new customers may require different levels of sales and marketing attention;

· new product launches in existing and new markets, as these launches typically involve more intense sales activity before they are integrated into customer applications;

· customer credit issues requiring increases to the allowance for doubtful accounts; and

· the implementation of cost control measures, including costs incurred in conjunction with restructuring activities, aimed at improving productivity and overall profitability.

Interest expense, net

Interest expense, net consists primarily of interest expense on institutional borrowings and other financing obligations. Interest expense, net also includes the amortization of deferred financing fees and debt discount associated with our financing agreements offset by interest income primarily associated with cash-on-hand. Factors affecting interest expense include fluctuations in the market interest rate, our borrowing activities and our outstanding debt balances.

Provision for income taxes

We and our subsidiaries are subject to income tax in the various jurisdictions in which we operate. While the extent of our future tax liability is uncertain, changes to the debt and equity capitalization of our subsidiaries and the realignment of the functions performed and risks assumed by the various subsidiaries are among the factors that will determine the future book and taxable income of the respective subsidiary and the Company as a whole.

Year Ended December 31, 2015 Compared to the Year Ended December 31, 2014

Net Sales

Net sales for 2015 decreased by $1,156.1 million, or 22.5%, to $3,971.9 million from $5,128.0 million in 2014. Of the 22.5% decrease in net sales, 17.3% was due to lower selling prices primarily due to the pass through of lower butadiene costs to our customers in Latex and Synthetic Rubber and lower styrene monomer costs to our customers in Latex and Basic Plastics & Feedstocks. In addition, 7.6% of the decrease was related to an unfavorable currency impact across our segments, as the U.S. dollar strengthened compared to the euro. Partially offsetting these decreases was a 2.4% increase due to higher sales volumes across our segments.

66

Cost of Sales

Cost of sales for 2015 decreased by $1,327.8 million, or 27.5%, to $3,502.8 million from $4,830.6 million in 2014. Of the 27.5% decrease, 22.5% was attributable to lower prices for raw materials, primarily butadiene and styrene monomer, while an additional 7.1% of the decrease was due to a favorable currency impact across our segments, as the U.S. dollar strengthened compared to the euro. Partially offsetting these decreases was a 2.1% increase due to higher sales volumes across our segments.

Gross Profit

Gross profit for 2015 increased by $171.7 million, or 57.7%, to $469.1 million from $297.4 million in 2014. The increase was primarily attributable to higher styrene monomer and styrenic polymer margins as well as higher polycarbonate margins due to our restructuring efforts and improved market dynamics. These impacts were partially offset by an unfavorable currency impact, as the U.S. dollar strengthened compared to the euro.

Selling, General and Administrative Expenses

SG&A expenses for 2015 decreased by $24.6 million, or 10.6%, to $208.0 million from $232.6 million in 2014. The decrease in SG&A expenses was primarily related to $23.3 million in termination fees incurred in the second quarter of 2014 related to the Advisory Agreement with Bain which we terminated upon consummation of the IPO in June 2014. In addition, the Company incurred lower restructuring charges during the year ended December 31, 2015 of $8.2 million, compared to charges of $14.1 million during the year ended December 31, 2014.  Refer to Note 20 in the consolidated financial statements for further details. These decreases were partially offset by increased costs related to other employee benefit costs.

Equity in Earnings of Unconsolidated Affiliates

Equity in earnings of unconsolidated affiliates for 2015 was $140.2 million compared to equity in earnings of $47.7 million for 2014. Equity earnings from Americas Styrenics increased to $135.3 million in 2015 from $50.3 million in 2014, due to stronger operating performance driven by higher styrene and polystyrene margins as well as higher volumes of styrene monomer sold. Sumika Styron Polycarbonate noted equity earnings of $4.9 million for 2015 compared to equity losses of $2.5 million in 2014.

Interest Expense, Net

Interest expense, net for the year ended December 31, 2015 was $93.2 million compared to $124.9 million for the year ended December 31, 2014. The decrease of $31.7 million is primarily attributable to the debt refinancing in May 2015. Refer to Note 10 in the consolidated financial statements for further details of this refinancing.

Loss on Extinguishment of Long-Term Debt

Loss on extinguishment of long-term debt was $95.2 million for the year ended December 31, 2015, related to the debt refinancing in May 2015. This amount was comprised of a $68.6 million call premium paid to retire the Company’s 2019 Senior Notes and a $25.9 million write-off of unamortized deferred financing fees related to these notes, as well as the write-off of $0.7 million of unamortized deferred financing fees related to the termination of the Company’s 2018 Revolving Facility.

Loss on extinguishment of long-term debt was $7.4 million for the year ended December 31, 2014, related to the redemption of $132.5 million in aggregate principal amount of the 2019 Senior Notes in July 2014, using proceeds from the Company’s IPO. This loss was comprised of a $4.0 million call premium and a $3.4 million write-off of related unamortized deferred financing fees.

Other Expense, net

Other expense, net for the year ended December 31, 2015 was $9.1 million, which consisted primarily of net foreign exchange transaction losses of approximately $10.4 million. These net foreign exchange transactions losses were comprised of foreign exchange transaction gains of $6.1 million primarily driven by the remeasurement of our euro denominated payables due to the strengthening of the U.S. dollar against the euro during the period, more than offset by

67

losses of $16.5 million recorded during the period related to the Company’s foreign exchange forward contracts.  Partially offsetting these net foreign exchange transactions losses was other miscellaneous income of $1.3 million.

Other expense, net for the year ended December 31, 2014 was $27.8 million, which included a $32.5 million payment made to Dow in connection with the termination of the Latex JV Option Agreement (see Note 18 in the consolidated financial statements), slightly offset by net foreign exchange transaction gains of $4.2 million and other income. These net foreign exchange transaction gains were comprised of foreign exchange transaction gains of $32.4 million primarily driven by the remeasurement of our euro denominated payables due to the strengthening of the U.S. dollar against the euro during the period. Separately, beginning in the third quarter of 2014, the Company entered into foreign exchange forward contracts and recorded related losses of approximately $28.2 million, largely offsetting the above described gains.

Provision for Income Taxes

Provision for income taxes for 2015 totaled $70.2 million resulting in an effective tax rate of 34.4%. Provision for income taxes for 2014 totaled $19.7 million resulting in a negative effective tax rate of 41.4%. The increase in provision for income taxes was primarily driven by the $251.5 million increase in income before income taxes, from a loss of $47.6 million for the year ended December 31, 2014 to $203.9 million of income for the year ended December 31, 2015.

These increases in the provision for income taxes in 2015 were offset by a reduction of losses generated within our holding companies incorporated in Luxembourg, which are not anticipated to provide a tax benefit to the Company in the future. For the year ended December 31, 2015, these losses totaled approximately $84.7 million. Included in these losses were payments made during the year ended December 31, 2015 of $19.0 million related to a portion of the fees associated with the call premium paid to retire the Company’s 2019 Senior Notes and $5.6 million related to the write off of the related unamortized deferred financing fees (see Note 10 in the consolidated financial statements for further discussion). Also included in these losses was non-deductible interest expense of $28.1 million and stock-based compensation expense.  Additionally, the overall increase in the provision for income taxes during the year was offset by the impact of a higher proportion of income in 2015 being attributable to non-U.S. jurisdictions, where the statutory income tax rate is lower than the U.S. statutory income tax rate.

For the year ended December 31, 2014, losses primarily within our holding companies incorporated in Luxembourg, which were not anticipated to provide a tax benefit to the Company in the future, were approximately $134.1 million. Included in these losses were payments made during the year ended December 31, 2014 of $32.5 million related to an agreement with Dow to terminate the Latex JV Option Agreement and a portion of the fees related to the termination of the Advisory Agreement with Bain Capital of approximately $18.6 million (see Note 18 in the consolidated financial statements for further discussion). Also included in these losses was non-deductible interest of $38.6 million and stock-based compensation expense.

In addition to the above, there were certain other one-time items impacting the provision for income taxes for the years ended December 31, 2015 and 2014, respectively.

For the year end December 31, 2015, the provision for income taxes was also unfavorably impacted by the recognition of a valuation allowance of $7.3 million on the net deferred tax asset of one of its China subsidiaries during the fourth quarter, as this entity was in a three year cumulative loss position as of December 31, 2015.  While the Company intends to realize the net operating loss carryforward before expiration due to forecasted profitability in this subsidiary in future years, it was unable to overcome the negative evidence of recent cumulative operating losses.  Therefore, the Company could not assert it would more likely than not be able to realize its deferred tax asset as of December 31, 2015.  If in the future, this subsidiary generates sufficient profitability such that the evaluation of recoverability of the deferred tax asset changes, the valuation allowance could be reversed.

For the year ended December 31, 2014, a tax benefit was recognized, as the Company effectively settled its 2010 and 2011 audits with the IRS and received a refund of $3.2 million in July 2014. As a result, the Company recorded a previously unrecognized tax benefit in the amount of $2.7 million, including penalties and interest, relating to its 2011 tax return filing. No similar benefits were recorded for the year ended December 31, 2015.

Year Ended December 31, 2014 Compared to the Year Ended December 31, 2013

Net Sales

Net sales for 2014 decreased by $179.4 million, or 3.4%, to $5,128.0 million from $5,307.4 million in 2013. Of the 3.4% decrease in net sales, 4.3% was due to lower selling prices, which was partially offset by a favorable currency impact of approximately 0.3% as the U.S. dollar weakened compared to the euro and a 0.5% increase in sales volume driven by the Synthetic Rubber segment. The overall decrease in selling prices was primarily due to the pass through of lower butadiene costs to our customers in Latex and Synthetic Rubber and styrene monomer to our customers in Latex and Basic Plastics & Feedstocks.

Cost of Sales

Cost of sales for 2014 decreased by $118.8 million, or 2.4%, to $4,830.6 million from $4,949.4 million in 2013. Of the 2.4% decrease, 0.7% was attributable to lower prices for raw materials, primarily butadiene and styrene monomer, while an additional 2.0% decrease was due to volume mix, as we had a decrease in higher cost products partially offsetting the increase in lower cost products. These decreases were partially offset by an unfavorable currency impact of approximately 0.3% due to the weakening of the U.S. dollar compared to the euro.

Gross Profit

Gross profit for 2014 decreased by $60.6 million, or 16.9%, to $297.4 million from $358.0 million in 2013. The decrease was primarily attributable to lower margins in the Basic Plastics & Feedstocks segment, driven by a reduction in the spread on styrene monomer production compared to the prior year. This decrease was partially offset by higher volume and margins in Synthetic Rubber.

Selling, General and Administrative Expenses

SG&A expenses for 2014 increased by $15.7 million, or 7.2%, to $232.6 million from $216.9 million in 2013. The increase in SG&A expenses was primarily due to $23.3 million in termination fees paid related to the Advisory Agreement with Bain Capital which terminated upon consummation of the initial public offering, or IPO, on June 17, 2014, and $10.1 million of accelerated depreciation and decommissioning charges incurred in connection with the restructuring of part of our Basic Plastics & Feedstocks segment to exit the commodity market for polycarbonate in North America. These increases were partially offset by higher restructuring charges incurred during the year ended December 31, 2013 of approximately $10.8 million related to the shutdown of our latex facility in Altona, Australia compared to charges of $2.8 million in 2014 for this shutdown, as well as a non-recurring charge in 2013 of $9.2 million from the impairment of fixed assets at our polycarbonate manufacturing plant in Stade, Germany. Other offsetting decreases in expenses included incentive compensation and other normal operating costs. The above one-time charges are discussed in further detail in our notes to the consolidated financial statements.

Equity in Earnings of Unconsolidated Affiliates

Equity in earnings of unconsolidated affiliates for 2014 was $47.7 million compared to equity in earnings of $39.1 million for 2013. Americas Styrenics, a strategic joint venture, equity earnings increased to $50.3 million in 2014 from $39.4 million in 2013, due to stronger operating performance driven by improved market conditions. These increased earnings were offset by reductions in the equity earnings of Sumika Styron Polycarbonate, another of our joint ventures, which decreased to equity in net losses of $2.5 million in 2014 from equity in net losses of $0.3 million in 2013.

Interest Expense, Net

Interest expense, net for the year ended December 31, 2014 was $124.9 million compared to $132.0 million for the year ended December 31, 2013. The decrease of $7.1 million is primarily attributable to the redemption of $132.5 million in aggregate principal amount of the 2019 Senior Notes in July 2014 as well as lower average borrowings and outstanding principal balances on both the 2018 Revolving Facility and the Accounts Receivable Securitization Facility during the year ended December 31, 2014 compared to the year ended December 31, 2013.

69

Loss on Extinguishment of Long-Term Debt

Loss on extinguishment of long-term debt was $7.4 million for the year ended December 31, 2014, related to the redemption of $132.5 million in aggregate principal amount of the 2019 Senior Notes in July 2014, using proceeds from the Company’s IPO. This loss was comprised of a $4.0 million call premium and a $3.4 million write-off of related unamortized deferred financing fees.

Loss on extinguishment of debt was $20.7 million for the year ended December 31, 2013, related to the extinguishment of our $1,239.0 million Term Loans under our 2018 Senior Secured Credit Facility, which was comprised of the write-off of existing unamortized deferred financing fees and original issue discount attributable to the Term Loans totaling $14.4 million and $6.3 million, respectively.

Other Expense, net

Other expense, net for the year ended December 31, 2014 was $27.8 million, which included a $32.5 million payment made to Dow in connection with the termination of the Latex JV Option Agreement (see Note 18 in the consolidated financial statements), slightly offset by net foreign exchange transaction gains of $4.2 million and other income. These net foreign exchange transaction gains were comprised of foreign exchange transaction gains of $32.4 million primarily driven by the remeasurement of our euro denominated payables due to the strengthening of the U.S. dollar against the euro during the period. Separately, beginning in the third quarter of 2014, the Company entered into foreign exchange forward contracts and recorded related losses of approximately $28.2 million, largely offsetting the above described gains.

Other expense, net for the year ended December 31, 2013 was $27.9 million, which consisted primarily of a $4.2 million loss on the sale of our EPS business within our Basic Plastics & Feedstocks segment and $18.9 million foreign exchange transaction losses primarily driven by the remeasurement of our euro payables to the U.S. dollar. The remaining other expenses, net include value-added taxes of approximately $2.5 million and other expenses.

Provision for Income Taxes

Provision for income taxes for 2014 totaled $19.7 million resulting in a negative effective tax rate of 41.4%. Provision for income taxes for 2013 totaled $21.8 million resulting in a negative effective tax rate of 5,921.0%.  

The decrease in provision for income taxes was driven by a reduction in income before taxes, from $0.4 million of loss for the year ended December 31, 2013 to $47.6 million of loss for the year ended December 31, 2014. This decrease in the provision for income taxes was partially offset by a lower proportion of income before taxes attributable to non-U.S. jurisdictions, where the statutory income tax rate is lower than the U.S. statutory income tax rate.  

Although the Company had losses before income taxes of $47.6 million for the year ended December 31, 2014, approximately $134.1 million of losses were generated primarily within our holding companies incorporated in Luxembourg, which did not provide a tax benefit to the Company and therefore unfavorably impacted the effective tax rate during the period. The most significant drivers of these losses are discussed above under the comparison of 2015 and 2014 results. Comparatively, the effective income tax rate for the year ended December 31, 2013 was impacted by losses of $97.2 million which were generated primarily within our holding companies incorporated in Luxembourg, related to non-deductible interest and stock-based compensation expense.  

Partially offsetting this unfavorable impact to the effective tax rate was the recognition of a previously unrecognized tax benefit in the amount of $2.7 million during the year ended December 31, 2014, related to the effective settlement of the Company’s 2010 and 2011 IRS audits mentioned above. No similar tax benefits were recorded for the year ended December 31, 2013.

(3) EBITDA is a non-GAAP financial measure that we refer to in making operating decisions because we believe it provides meaningful supplemental information regarding our operational performance. We present EBITDA because we believe that it is useful for investors to analyze disclosures of our operating results on the same basis as that used by our management. 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 because it removes the impact of our capital structure (such as interest expense), asset base (such as depreciation and amortization) and tax structure. See a reconciliation of net income (loss) to EBITDA below:

	Year Ended
	December 31,
(in millions)	2015		2014		2013
Net income (loss)	$	133.6	$	(67.3)	$	(22.2)
Interest expense, net		93.2		124.9		132.0
Provision for income taxes		70.2		19.7		21.8
Depreciation and amortization		96.8		103.7		95.2
EBITDA	$	393.8	$	181.0	$	226.8

There are limitations to using financial measures such as EBITDA. 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 (loss), which is determined in accordance with GAAP.

Latex Segment

We are a global leader in SB latex, holding a strong market position across the geographies and applications in which we compete, including the #1 position in SB latex in Europe and the #2 position in North America. We produce SB latex primarily for coated paper used in advertising and magazines, packaging board coatings, carpet and artificial turf backings, as well as a number of performance latex applications. In 2015, approximately 45% of our Latex segment’s sales were generated in Europe, 26% were generated in the United States, and the majority of the remaining net sales were generated in Asia.

Year Ended December 31, 2015 Compared to the Year Ended December 31, 2014

Net sales for 2015 decreased by $294.9 million, or 23.4%, to $966.2 million from $1,261.1 million for 2014. Of the 23.4% decrease in net sales, 21.0% was due lower selling prices primarily due to the pass through of lower butadiene and styrene costs to our customers and 5.6% was due to an unfavorable currency impact as the U.S. dollar strengthened compared to the euro. These decreases were slightly offset by a 3.3% increase from higher sales volume driven by higher sales to the Europe paper and carpet markets.

EBITDA for 2015 decreased by $15.3 million, or 16.3%, to $78.7 million from $94.0 million in 2014. Of this decrease, 14.0% was driven by lower margins, primarily in Europe and Asia, and 3.9% was driven by an unfavorable currency impact as the U.S. dollar strengthened compared to the euro. In addition, 6.3% of the decrease was due to increased fixed costs. Partially offsetting these decreases was an 8.1% increase in sales volume primarily related to increased sales to the Europe paper and carpet markets.

Year Ended December 31, 2014 Compared to the Year Ended December 31, 2013

Net sales for 2014 decreased by $80.3 million, or 6.0%, to $1,261.1 million from $1,341.4 million for 2013. Of the 6.0% decrease in net sales, 4.9% was due to lower selling prices primarily from the pass through of lower butadiene and styrene cost and 1.3% from lower sales volume driven by lower sales to the Europe and North America paper markets, partially offset by higher sales to the Asia paper market as well as to the global flooring and performance latex markets.

72

There was also a 0.2% favorable currency impact in 2014 compared to the prior year as the U.S. dollar weakened compared to the euro.

EBITDA for 2014 decreased by $1.4 million, or 1.5%, to $94.0 million from $95.4 million in 2013. Of this decrease, 10.1% was driven by lower sales volume and margins due to lower demand and continued increases in competition in coated paper markets. These decreases were partially offset by a decrease in non-recurring restructuring related charges of $8.0 million from 2013 (see Note 20 in the consolidated financial statements) in connection with the closure of the latex plant in Australia.

Synthetic Rubber Segment

We are a significant producer of styrene-butadiene and polybutadiene-based rubber products and we have a leading European market position in SSBR. While substantially all of our sales were generated in Europe in 2015, approximately 19% of these net sales were exported to Asia, 7% to Latin America and 9% to North America.

We have a broad synthetic rubber technology and product portfolio, focusing on specialty products, such as SSBR, Li-PBR, and Nd-PBR, while also producing core products, such as ESBR. Our synthetic rubber products are extensively used in tires, with approximately 83% of our net sales from this segment in 2015 attributable to the tire market. We estimate that three quarters of these sales relate to replacement tires. We have strong relationships with many of the top global tire manufacturers and believe we have remained a supplier of choice as a result of our broad rubber portfolio and ability to offer technologically differentiated product and product customization capabilities. Other applications for our synthetic rubber products include polymer modification and technical rubber goods.

Year Ended December 31, 2015 Compared to Year Ended December 31, 2014

Net sales for 2015 decreased by $159.4 million, or 25.1%, to $474.6 million from $634.0 million in 2014. Of the 25.1% decrease in net sales, 19.7% was due to lower selling prices primarily resulting from the pass through of lower butadiene and styrene costs to customers and 11.6% was due to an unfavorable currency impact as the U.S. dollar strengthened compared to the euro. These decreases were slightly offset by a 6.2% increase from higher sales volume resulting from higher sales of SSBR to tire producers.

EBITDA for 2015 decreased by $44.0 million, or 32.1%, to $93.0 million from $137.0 million for 2014. Of this decrease, 25.6% was driven by lower margins, including impacts from the timing of raw material costs, and an unfavorable currency impact of approximately 7.8% as the U.S. dollar strengthened compared to the euro. In addition, 8.4% of the decrease was driven by higher fixed costs due primarily to higher planned maintenance expense in the current year as well as higher employee benefit costs. Partially offsetting these decreases was a 9.5% increase due to sales volume driven by higher SSBR sales.

Year Ended December 31, 2014 Compared to the Year Ended December 31, 2013

Net sales for 2014 increased by $11.9 million, or 1.9%, to $634.0 million from $622.1 million in 2013. Of the 1.9% increase in net sales, 8.6% was due to an increase in sales volume resulting from higher sales of SSBR to tire producers, and 0.6% was due to a favorable currency impact as the U.S dollar weakened compared to the euro. These increases were partially offset by lower selling prices due to the pass through of lower butadiene costs to customers, which decreased net sales by approximately 7.2%.

EBITDA for 2014 increased by $23.5 million, or 20.7%, to $137.0 million from $113.5 million for 2013. Higher volume, driven by higher SSBR sales, and margin, driven by favorable raw material cost timing, increased EBITDA by approximately 28.0%. In addition, currency had a favorable impact of approximately 0.5% as the U.S. dollar weakened compared to the euro. These increases were partially offset by higher fixed costs, which decreased EBITDA by approximately 7.6%, driven by a lower level of fixed cost absorption.

Performance Plastics Segment

We are a producer of highly engineered compounds and blends for automotive end markets, as well as consumer electronics, medical, and electrical lighting, which we collectively call consumer essential markets (CEM). Our strategy in this segment focuses on developing differentiated compounds and blends in line with key industry trends, such as

73

light-weighting and improved aesthetics in automotive, increased recycled material content and a push toward LED lighting in CEM.  Our history of innovation has contributed to long-standing relationships with customers who are recognized leaders in their respective end-markets. We have established a strong market presence in the global automotive and electronics sector, targeting both component suppliers and final product manufacturers. Our Performance Plastics segment also compounds and blends our PC and mABS plastics into differentiated products for customers within these sectors, as well as into compounds of polypropylene. We have also developed compounds containing post-consumer recycle polymers to respond to what we believe is a growing need for some customers to include recycled content in their products.

We believe growth in this segment is driven by a number of factors, including consumer preference for lighter weight and impact-resistant products and the development of new consumer electronics, increases in LED lighting applications and continuing growth in medical device applications. Additionally, we believe growth is bolstered by sustainability trends, such as the substitution of lighter-weight plastics for metal in automobiles, as well as more energy efficient, glazing solutions.

In 2015, approximately 38% of our Performance Plastics segment’s net sales were generated in Europe, approximately 27% were generated in the United States, and approximately 22% were generated in Asia, with the remainder in other geographic regions, including Latin America and Canada.

In automotive end applications, we aim to maintain and develop sustainable, long-standing relationships with industry leaders, taking advantage of our production capacity located across four continents to drive original equipment manufacturer, or OEM, platform design wins. In 2015, we experienced growth in sales related to the automotive market, with a 2% increase in sales volume outside of Latin America, which experienced declines due to lower consumer confidence and higher interest rates. We continue to focus on our strategic plans to grow this segment through both current technologies and expanded offerings for car exteriors and semi-structural applications.

In CEM, sales volume for 2015 was up 9% over 2014, driven largely by the consumer electronics industry in Asia and by significant progress during the year with our lighting customers, including materials for LED housings and lenses.

Year Ended December 31, 2015 Compared to Year Ended December 31, 2014

Net sales for 2015 decreased by $78.3 million, or 9.5%, to $742.8 million from $821.1 million in 2014. Of the 9.5% decrease in net sales, 6.2% was due to lower selling prices primarily related to the pass through of lower raw material costs to our customers and 5.6% was due to an unfavorable currency impact as the U.S. dollar strengthened compared to the euro. These decreases were partially offset by a 2.2% increase in sales volume, primarily related to the consumer electronics market in Asia as well as the automotive market in North America.

EBITDA for 2015 increased by $13.6 million, or 19.6%, to $83.0 million from $69.4 million in 2014. The EBITDA increase was driven by an increase in sales volume, primarily related to the consumer electronics market in Asia and the automotive market in North America, as well as higher margins due to lower raw material costs, which contributed to 36.4% of the increase. Slightly offsetting this increase was a 14.7% decrease due to increased fixed costs, including higher employee benefit costs.

Year Ended December 31, 2014 Compared to the Year Ended December 31, 2013

Net sales for 2014 increased by $13.5 million, or 1.7%, to $821.1 million from $807.6 million in 2013. Of the 1.7% increase in net sales, 1.6% was driven by an increase in sales volume from higher sales to the Europe, North America, and Asia automotive markets as well as the Asia electronics market. A favorable currency impact, as the U.S. dollar weakened compared to the euro, increased sales by 0.2%. These increases were partially offset by a 0.2% decrease in selling prices due primarily to the pass through of lower raw material cost.

EBITDA for 2014 increased by $7.8 million, or 12.7%, to $69.4 million from $61.6 million in 2013. This increase was primarily due to higher volume and margins in 2014 from sales of our compounds and blends products to the automotive and electronic markets which contributed to 28.1% of the increase. This increase was partially offset by increased fixed costs primarily related to additional resources focused on improving business performance and growth, which decreased EBITDA by 15.9%.

Basic Plastics and Feedstocks Segment

Basic Plastics & Feedstocks consists of styrenic polymers, including polystyrene, ABS, and SAN products, as well as PC and styrene monomer, which includes our internal productions and sourcing of styrene.  This segment also includes the results of our two joint ventures, Americas Styrenics and Sumika Styron Polycarbonate. We do not anticipate investing in strategic growth initiatives in this segment in the near term. Rather, our strategy for this segment is focused on operational enhancements, margin improvement, and cash generation.

We are a leading producer of polystyrene and mABS, where we focus our efforts on differentiated applications such as the liners and encasements of appliances and consumer electronics including smartphones and tablets.  Within these applications, we have worked collaboratively with customers to develop more advanced grades of plastics such as our HIPS and mABS products.  For example, we work with appliance manufacturers around the world to develop improved environmental stress crack resistant products and with our construction sheet customers on smooth ABS.  These products offer superior properties, such as rigidity, insulation and colorability, and, in some cases, an improved environmental footprint compared to general purpose polystyrene or emulsion ABS.  Our Basic Plastics & Feedstocks segment also serves the packaging and construction end-markets, where we have launched a new general purpose polystyrene product for improved performance in foam insulation applications.

PC has high levels of clarity, impact resistance and temperature resistance. PC can be used in its neat form (prior to any compounding or blending) for markets such as construction sheet, optical media and LED lighting.  Additionally, PC can be compounded or blended with other polymers, such as ABS, which imparts specific performance attributes tailored to the product’s end-use.  A significant portion of our PC is consumed in our Performance Plastics segment for the manufacture of our compounds and blends products. We continue to drive improvements in profitability of PC as a result of savings from our restructuring activities, as well as from improvements in industry supply and demand.

Year Ended December 31, 2015 Compared to Year Ended December 31, 2014

Net sales for 2015 decreased by $623.5 million, or 25.9%, to $1,788.3 million from $2,411.8 million in 2014. Of the 25.9% decrease in net sales, 18.6% was driven by decreases in selling prices due primarily to the pass through of lower styrene costs to customers and 8.3% was due to unfavorable currency impact as the U.S. dollar strengthened compared to the euro.

EBITDA for 2015 increased by $302.4 million, or 1,265.3%, to $326.3 million from $23.9 million in 2014. The EBITDA increase was due primarily to higher margins, particularly in styrene monomer and styrenic polymers, as well as in polycarbonate as a result of our restructuring efforts and improved market conditions. In addition, increased equity earnings from our two joint ventures, primarily Americas Styrenics, contributed to $92.7 million of the increase, or 387.9%. Increased equity earnings from Americas Styrenics was driven by higher styrene and polystyrene margins as well as higher volumes of styrene monomer sold. Partially offsetting these increases was a 133.1% unfavorable currency impact as the U.S. dollar strengthened compared to the euro.

Year Ended December 31, 2014 Compared to the Year Ended December 31, 2013

Net sales for 2014 decreased by $124.5 million, or 4.9%, to $2,411.8 million from $2,536.3 million in 2013. Of the 4.9% decrease in net sales, 4.5% was driven by decreases in selling prices primarily due to the pass through of lower styrene costs to customers and approximately 0.7% was due to a decrease in sales volume. These decreases were partially offset by a 0.4% favorable currency impact to our net sales as the U.S. dollar weakened compared to the euro.

EBITDA for 2014 decreased by $66.1 million, or 73.4%, to $23.9 million from $90.0 million in 2013. Of the 73.4% decrease, 97.9% was driven by lower margins due mainly to a reduction in the spread on styrene monomer production margins compared to prior year as well as lower PC margins from weaker market conditions. Also contributing to the decrease was a 12.0% reduction in sales volume, driven by lower sales in Europe and Asia polystyrene, which includes impacts from customer destocking in the latter half of the year with decreasing prices. These impacts were partially offset by a 22.2% increase in EBITDA due to lower fixed costs, primarily related to fixed cost savings from our exit of the Freeport, Texas polycarbonate contract manufacturing agreement net of $6.6 million of decommissioning charges incurred in connection with this exit.  In addition, the decrease in EBITDA was partially offset by the one-time $9.2 million impairment of fixed assets charge at our polycarbonate manufacturing facility in Stade,

75

Germany that was incurred in 2013 as well as an increase in equity earnings from our Americas Styrenics joint venture, which increased $10.9 million compared to the prior year.

Other Important Performance Measures

We believe that the presentation of Adjusted EBITDA and Adjusted EBITDA excluding inventory revaluation provides investors with a useful analytical indicator of our performance and of our ability to service our indebtedness.

We define Adjusted EBITDA as income (loss) from continuing operations before interest expense, net; income tax provision; depreciation and amortization expense; loss on extinguishment of long-term debt; asset impairment charges; advisory fees paid to affiliates of Bain Capital; gains or losses on the dispositions of businesses and assets; restructuring and other non-recurring items. We describe these other costs in more detail below.

We present Adjusted EBITDA excluding inventory revaluation in order to facilitate the comparability of results from period to period by adjusting cost of sales to reflect the cost of raw material during the period, which is often referred to as the replacement cost method of inventory valuation. We believe this measure minimizes the impact of raw material purchase price volatility in evaluating our performance. Our approach to calculating inventory revaluation is intended to represent the difference between the results under the FIFO and the replacement cost methods. However, our calculation could differ from the replacement cost method if the monthly raw material standards are different from the actual raw material prices during the month and production and purchase volumes differ from sales volumes during the month. These factors could have a significant impact on the inventory revaluation calculation.

There are limitations to using financial measures such as Adjusted EBITDA and Adjusted EBITDA excluding inventory revaluation. These performance measures are not intended to represent cash flow from operations as defined by GAAP and should not be used as alternatives to net income (loss) as indicators of operating performance or to cash flow as measures of liquidity. Other companies in our industry may define Adjusted EBITDA and Adjusted EBITDA excluding inventory revaluation differently than we do. As a result, it may be difficult to use these 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 these performance measures to our net income (loss), which is determined in accordance with GAAP.

Adjusted EBITDA and Adjusted EBITDA excluding inventory revaluation are calculated as follows for the years ended December 31, 2015, 2014, and 2013, respectively:

(a) We refer to EBITDA in making operating decisions because we believe it provides meaningful supplemental information regarding our operational performance. 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 (loss), which is determined in accordance with GAAP. See the “Selected Segment Information” for further detail.

(b) Asset impairment charges or write-offs for the year ended December 31, 2013 relate primarily to a $9.2 million impairment charge for fixed assets at our polycarbonate manufacturing plant in Stade, Germany. See Note 7 in the consolidated financial statements for further discussion.

(c) Net loss (gain) on disposition of businesses and assets for the years ended December 31, 2014 and 2013 of $(0.6) million and $4.2 million, respectively, relate to the sale of the Company’s EPS business, which closed in September 2013, and for which a contingent gain of $0.6 million was recorded during the fourth quarter of 2014. Refer to Note 3 in the consolidated financial statements for further discussion.

(d) Restructuring and other charges for the year ended December 31, 2015 relate primarily to the polycarbonate restructuring within our Basic Plastics & Feedstocks segment for the reimbursement of decommissioning and demolition charges to Dow in connection with the shutdown of their Freeport, Texas facility and employee termination benefit charges incurred in connection with the Allyn’s Point shutdown within our latex business. Restructuring and other charges for the years ended December 31, 2014 and 2013 were incurred primarily in connection with the shutdown of our latex manufacturing plant in Altona, Australia and the restructuring within our Basic Plastics & Feedstocks segment noted above.Note that the accelerated depreciation charges incurred as a  part of the Allyn’s Point shutdown announced in September 2015, and the 2014 restructuring within our Basic Plastics & Feedstocks segment, are included within the “Depreciation and amortization” caption above, and therefore are not included as a separate adjustment within this caption. See Note 20 in the consolidated financial statements for further discussion.

(e) Represents fees paid under the terms of our advisory agreement with Bain Capital (the “Advisory Agreement”). For the year ended December 31, 2014, this includes a charge of $23.3 million for fees incurred in connection with the termination of the Advisory Agreement, pursuant to its terms, upon consummation of the Company’s IPO in June 2014. See Note 18 in the consolidated financial statements for further discussion.

(f) Other non-recurring items incurred for the years ended December 31, 2015 and 2014 primarily consist of costs related to the process of changing our corporate name from Styron to Trinseo. For the year ended December 31, 2014,these costs also include a one-time $32.5 million termination payment made to Dow in connection with the termination of our Latex JV Option Agreement. See Note 18 in the consolidated financial statements for further discussion.

(g) See the discussion above this table for a description of Adjusted EBITDA excluding inventory revaluation.

Liquidity and Capital Resources

Cash Flows

The table below summarizes our primary sources and uses of cash for the years ended December 31, 2015, 2014, and 2013. We have derived the summarized cash flow information from our audited financial statements.

77

	Year Ended
	December 31,
(in millions)	2015		2014		2013
Net cash provided by (used in):
Operating activities	$	353.2	$	117.2	$	211.3
Investing activities		(106.7)		(92.6)		(33.4)

Effect of exchange rates on cash		(9.8)		(8.4)		2.4
Net change in cash and cash equivalents	$	210.5	$	24.3	$	(39.9)

Operating Activities

Net cash provided by operating activities during the year ended December 31, 2015 totaled $353.2 million, driven by the overall strong earnings for the period. Also driving the strong positive cash from operating activities for the period was $125.0 million in dividends from our joint venture, Americas Styrenics.  These increases were noted despite several significant decreases to operating cash flows, which included $81.7 million in interest payments made on our 2019 Senior Notes prior to their May 2015 retirement as well as a $68.6 million call premium paid to retire those notes.  Refer to Note 10 in the consolidated financial statements for further details.

Net cash provided by operating assets and liabilities for the year ended December 31, 2015 totaled $103.9 million, the most significant components of which were decreases in inventories of $97.2 million and decreases in accounts receivable of $65.1 million, offset by a decrease in accounts payables and other current liabilities of $71.9 million. Inventory decreased due to higher volume sold during the fourth quarter of 2015 when compared to the fourth quarter of 2014, as well as significant decreases in raw materials prices when comparing the periods. The decrease in accounts receivable is primarily due to lower sales and higher collections during the fourth quarter of 2015, compared to the fourth quarter of 2014, primarily driven by decreasing raw material prices. The decrease in accounts payable and other current liabilities is primarily due to timing of payments as well as decreases in prices for raw materials purchases.

Net cash provided by operating activities during the year ended December 31, 2014 totaled $117.2 million, with net cash provided by operating assets and liabilities totaling $61.1 million. The most significant components of the changes in operating assets and liabilities for the year ended December 31, 2014 of $61.1 million was a decrease in accounts receivable of $68.5 million and a decrease in inventories of $22.6 million, offset by a decrease in other liabilities of $22.0 million. The decrease in accounts receivable is primarily due to lower sales and higher collections during the fourth quarter of 2014, compared to the fourth quarter of 2013, primarily driven by decreasing raw material prices. Our other liabilities decreased mainly due to reductions in normal operating costs. Our operating cash flow for the year ended December 31, 2014 was negatively impacted by two significant one-time cash payments in the second quarter of 2014 totaling approximately $55.8 million related to the termination of our Latex JV Option Agreement with Dow and our Advisory Agreement with Bain Capital. Refer to Note 18 of the consolidated financial statements for further discussion.

Net cash provided by operating activities during the year ended December 31, 2013 totaled $211.3 million, with net cash provided by operating assets and liabilities totaling $92.5 million. The most significant components of the changes in operating assets and liabilities for the year ended December 31, 2013 of $92.5 million were increases in accounts payable and other current liabilities of $15.0 million, and a decrease in inventory of $55.4 million. Increase in accounts payable and other current liabilities was mainly due to timing of payments in the normal course of business plus lesser interest payments in 2013 on the 2019 Senior Notes as interest payments are due semi-annually in August and February each year compared to interest on the Term Loans which were paid quarterly in the prior year. Decrease in inventory was due to lower raw materials prices during 2013, as well as a decrease in volumes compared to the fourth quarter of 2012, due to higher inventory volumes on hand at the end of 2012 resulting from our rubber capacity expansion project placed in operation in the fourth quarter of 2012. Additionally, in 2013 we received $22.5 million from our unconsolidated affiliate, Americas Styrenics, as a return on our investment. Overall, cash flow from operating activities was primarily driven by improvement in cash collection during the year and lesser cash outflow on purchases due to inventory build in 2012 and lower raw materials prices in 2013.

78

Investing Activities

Net cash used in investing activities for the year ended December 31, 2015 totaled $106.7 million, consisting primarily of capital expenditures of $107.1 million during the period, net of proceeds received from a government subsidy of $2.2 million related to our capital expansion project at our rubber facility in Schkopau, Germany.

Net cash used in investing activities for the year ended December 31, 2014 totaled $92.6 million consisting primarily of capital expenditures of $98.6 million, of which approximately $26.1 million (€19.0 million) was related to the Company’s acquisition of production capacity rights from JSR at its rubber production facility in Schkopau, Germany. These investing activities were partially offset by cash proceeds of $6.3 million from the sale of a portion of land at our manufacturing site in Livorno, Italy.

Net cash used in investing activities for the year ended December 31, 2013 totaled $33.4 million, consisting primarily of capital expenditures of $54.8 million during the period, net of proceeds received from a government subsidy of $18.8 million related to our capital expansion project at our rubber facility in Schkopau, Germany. Also offsetting these capital expenditures were cash proceeds of $15.2 million received from the sale of our EPS business during the year as well as cash proceeds of $7.9 million released from restrictions related to our accounts receivable securitization facility. Refer to Note 3 of the consolidated financial statements for details on the EPS business divestiture.

Financing Activities

Net cash used in financing activities during the year ended December 31, 2015 totaled $26.2 million. The most significant activity during the period related to the May 2015 debt refinancing, which included net proceeds of $1,215.4 million from the issuance of our 2021 Term Loan B and our 2022 Senior Notes, offset by the retirement of our existing 2019 Senior Notes totaling $1,192.5 million and deferred financing fees paid in conjunction with the refinancing of $28.2 million. Also during the period, we had net repayments of short-term borrowings of $18.4 million, which largely consisted of borrowings under our short-term revolving credit facility through our subsidiary in China.  On a limited basis, we continued to utilize our Accounts Receivable Securitization Facility to fund our working capital requirements. For the year ended December 31, 2015, we had borrowings from and repayments of our Accounts Receivable Securitization Facility of $25.0 million.

Net cash provided by financing activities during the year ended December 31, 2014 totaled $8.1 million. During the period, the Company completed the IPO of 11,500,000 ordinary shares at a price of $19.00 per share. As a result, the Company received net cash proceeds from the issuance of ordinary shares of $198.1 million, which was net of underwriting discounts as well as advisory, accounting, and legal expenses directly related to the offering. In July 2014, using proceeds from the Company’s IPO, the Company redeemed $132.5 million in aggregate principal amount of the 2019 Senior Notes. In addition, we had net repayments of short-term borrowings of $56.9 million, which largely consisted of borrowings under our short-term revolving credit facility through our subsidiary in China. We also continued to utilize our Accounts Receivable Securitization Facility to fund our working capital requirements. For the year ended December 31, 2014, we had borrowings from our Accounts Receivable Securitization Facility of $308.6 million and repayments of $309.2 million, resulting in net repayments of $0.6 million due to changes in foreign currency exchange rates, as a portion of our borrowings under the Accounts Receivable Securitization Facility originate in euros.

Net cash used in financing activities during the year ended December 31, 2013 totaled $220.2 million. During the period, we repaid our outstanding Term Loans of $1,239.0 million using the proceeds from the issuance of $1,325.0 million 2019 Senior Notes issued in January 2013. In connection with the issuance of the 2019 Senior Notes and the amendments to our 2018 Senior Secured Credit Facility and our Accounts Receivable Securitization Facility, we paid approximately $48.3 million of refinancing fees. In addition, during the period, we continued to utilize our 2018 Revolving Facility and our Accounts Receivable Securitization Facility to fund our working capital requirements. During the year ended December 31, 2013, our borrowings and repayments to our 2018 Revolving Facility were $405.0 million and $525.0 million, respectively, and we had net repayments to our Accounts Receivable Securitization Facility of $95.1 million.

2018 Senior Secured Credit Facility

On June 17, 2010, the Company entered into the 2018 Senior Secured Credit Facility, under which the Company entered into the 2018 Revolving Facility, which, as a result of an amendment in January 2013, included a borrowing capacity of $300.0 million. As of December 31, 2014, the Company had no amounts outstanding under this facility. In May 2015, upon completion of the refinancing transactions discussed below, the Company terminated the 2018 Senior Secured Credit Facility.  Prior to this termination, the Company had no outstanding borrowings under the 2018 Revolving Facility.  Interest charges incurred during the years ended December 31, 2015 and 2014, respectively, related primarily to unused commitment fees incurred.

Senior Credit Facility

On May 5, 2015, the Borrowers, entered into the Credit Agreement, which provides senior secured financing of up to $825.0 million, defined as the Senior Credit Facility.  The Senior Credit Facility provides for senior secured financing consisting of the (i) 2020 Revolving Facility including a $325.0 revolving credit facility, with a $25.0 million swingline subfacility and a $35.0 million letter of credit subfacility maturing in May 2020 and (ii) $500.0 million senior secured 2021 Term Loan B (maturing in November 2021). Amounts under the 2020 Revolving Facility are available in U.S. dollars and euros.

The 2021 Term Loan B bears an interest rate of LIBOR plus 3.25%, subject to a 1.00% LIBOR floor, and was issued at a 0.25% original issue discount.  Further, the 2021 Term Loan B requires scheduled quarterly payments in amounts equal to 0.25% of the original principal amount of the 2021 Term Loan B, with the balance to be paid at maturity. During the year ended December 31, 2015, the Company made principal payments of  $2.5 million related to the 2021 Term Loan B. As of December 31, 2015, $5.0 million of these scheduled future payments were classified as current debt on the Company’s consolidated balance sheet.

Loans under the 2020 Revolving Facility, at the Borrowers’ option, may be maintained as (a) LIBO rate loans, which bear interest at a rate per annum equal to the LIBO rate plus the applicable margin (as defined in the Credit Agreement), if applicable, or (b) base rate loans which shall bear interest at a rate per annum equal to the base rate plus the applicable margin (as defined in the Credit Agreement).  As of December 31, 2015, the Borrowers will be required to pay a quarterly commitment fee in respect of any unused commitments under the 2020 Revolving Facility equal to 0.375% per annum.

80

As of December 31, 2015, the Company had no outstanding borrowings, and had $311.5 million (net of $13.5 million outstanding letters of credit) of funds available for borrowings under the 2020 Revolving Facility.

Refer to Note 10 of the consolidated financial statements for detailed description of requirements, guarantees, affirmative and negative covenants, and financial covenants to which the Borrowers and their subsidiaries are subject under the Senior Credit Facility.  As of December 31, 2015, the Company was in compliance with all debt covenant requirements under the Senior Credit Facility.

2019 Senior Notes

In January 2013, the Company issued $1,325.0 million 8.750% 2019 Senior Notes due to mature on February 1, 2019. In July 2014, using proceeds from the Company’s IPO, the Company redeemed $132.5 million in aggregate principal amount of the 2019 Senior Notes,together with a 103% call premium totaling $4.0 million and accrued and unpaid interest thereon of $5.2 million.  

On May 13, 2015, using the net proceeds from the issuance of the 2021 Term Loan B, together with the net proceeds from the issuance of the 2022 Senior Notes (discussed below) and available cash, the Company redeemed all outstanding borrowings under the 2019 Senior Notes, totaling $1,192.5 million in principal, together with a call premium of $68.6 million and accrued and unpaid interest thereon of $29.6 million.

2022 Senior Notes

On May 5, 2015, the Issuers executed the Indenture pursuant to which they issued $300.0 million aggregate principal amount of 6.750% USD Notes due May 1, 2022 and €375.0 million aggregate principal amount of 6.375% Euro Notes due May 1, 2022 (together, the 2022 Senior Notes).  Interest on the 2022 Senior Notes is payable semi-annually on May 1 and November 1 of each year, commencing on November 1, 2015.

At any time prior to May 1, 2018, the Issuers may redeem the 2022 Senior Notes in whole or in part, at their option at a redemption price equal to 100% of the principal amount of such notes plus the relevant applicable premium as of, and accrued and unpaid interest to, but not including, the redemption date. At any time and from time to time after May 1, 2018, the Issuers may redeem the 2022 Senior Notes, in whole or in part, at a redemption price equal to the percentage of principal amount set forth below plus accrued and unpaid interest, if any, on the notes redeemed to, but not including, the redemption date:

	Euro Notes		USD Notes
12-month period commencing May 1 in Year	Percentage		Percentage
2018	103.188	%	103.375	%
2019	101.594	%	101.688	%
2020 and thereafter	100.000	%	100.000	%

In addition, at any time prior to May 1, 2018, the Issuers may redeem up to 40% of the aggregate principal amount of each of the USD Notes and the Euro Notes, either together or separately, at a redemption price equal to 106.750% of the principal amount thereof for the USD Notes and 106.375% of the principal amount thereof for the Euro Notes plus, in each case, accrued and unpaid interest to, but not including, the redemption date, in an amount equal to the aggregate gross proceeds from certain equity offerings.

Refer to Note 10 of the consolidated financial statements for detailed description of requirements, guarantees, and customary covenants to which the Issuers and their subsidiaries are subject under the Indenture.  As of December31, 2015, the Company was in compliance with all debt covenant requirements under the Indenture.

Accounts Receivable Securitization Facility

As of December 31, 2015, the Company’s Accounts Receivable Securitization Facility had a borrowing capacity of $200.0 million and a maturity date of May 2016.  In February 2016, the maturity date was extended to May 2019. The Accounts Receivable Securitization Facility is subject to interest charges against the amount of outstanding borrowings as well as the amount of available, but undrawn commitments. As a result of the amendment to our Accounts Receivable Securitization Facility, in regards to outstanding borrowings, fixed interest charges decreased from 3.25% plus commercial paper rates to 2.60% plus variable commercial paper rates. In regards to available, but undrawn commitments, fixed interest charges decreased from 1.50% to 1.40%.

81

As of December 31, 2015, there were no amounts outstanding under the Accounts Receivable Securitization Facility, with approximately $123.4 million of funds available for borrowing under this facility, based on the pool of eligible accounts receivable.

Other indebtedness

As of December 31, 2015, we had no outstanding borrowings under our short-term revolving credit facility through our subsidiary in China that provides uncommitted funds available for borrowing, subject to the availability of collateral. The facility is subject to annual renewal.

Derivative Instruments

The Company’s ongoing global business operations expose it to fluctuating foreign exchange rates.  To manage this risk, the Company periodically enters into derivative financial instruments such as foreign exchange forward contracts.  A brief summary of these derivative financial instrument programs is described below; however, refer to Note 11 of the consolidated financial statements for further details. The Company does not hold or enter into financial instruments for trading or speculative purposes.

Foreign Exchange Forward Contracts

Certain subsidiaries have assets and liabilities denominated in currencies other than their respective functional currencies, which creates foreign exchange risk. Our principal strategy in managing 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 our 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.

Foreign Exchange Cash Flow Hedges

In 2015, the Company began entering 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.

Net Investment Hedge

The Company’s outstanding debt includes €375.0 million of Euro Notes (discussed above).  As of December 31, 2015, the Company has designated a portion (€150.0 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.

Capital Resources and Liquidity

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. We believe, based on our current level of operations, that these sources of liquidity will be sufficient to fund our operations, capital expenditures and debt service for at least the next twelve months.

Our liquidity requirements are significant due to interest owed on our outstanding indebtedness, capital expenditures and our working capital requirements. As of December 31, 2015, we had $1,207.8 million in outstanding indebtedness and $839.8 million in working capital. As of December 31, 2014, we had $1,202.2 million in outstanding indebtedness and $748.7 million in working capital. As of December 31, 2015 and December 31, 2014, we had $73.7 million and $94.7 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

82

foreign cash and cash equivalents. Accordingly, we record deferred income tax liabilities related to the unremitted earnings of our subsidiaries.

As discussed above, in May 2015, we terminated our existing 2018 Senior Secured Credit Facility and entered into the new Senior Credit Facility, which increased the borrowing capacity under our new revolving facility to $325.0 million and extended the maturity to May 2020.  Also in May 2015, we redeemed our existing 2019 Senior Notes totaling $1,192.5 million, replacing those borrowings with the $500.0 million 2021 Term Loan B along with the $300.0 million USD Notes and €375.0 million Euro Notes, both due May 2022. We also continue to maintain our Accounts Receivable Securitization Facility set to mature in May 2016, under which our borrowing capacity is $200.0 million.

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 direct or indirect 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 ventures in order to satisfy their debt obligations.  There are no known significant restrictions by third parties on the ability of subsidiaries of the Company to disburse or dividend funds to the Issuers and the Borrowers in order to satisfy these obligations.  However, as the Company’s subsidiaries are located in a variety of jurisdictions, the Company can give no assurances that its subsidiaries will not face transfer restrictions in the future due to regulatory or other reasons beyond our control.

Further, we cannot make assurances that 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. As of December 31, 2015 and 2014, we were in compliance with all the covenants and default provisions under our debt agreements.

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.  However, as of December 31, 2015, the Trinseo S.A. had no significant existing obligations or declared dividends to shareholders.  Further, as of December 31, 2015, there was sufficient capacity under existing restricted payment criteria of the Senior Credit Facility and Indenture to provide for any anticipated or potential future requirements, should the Company elect to declare dividends or other distributions.

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. However, if we were to undertake any significant acquisitions or investments, it may be necessary for us to obtain additional debt or equity financings. We may not be able to obtain such financing on reasonable terms, or at all.

(1) We have certain raw material purchase contracts where we are required to purchase certain minimum volumes at the then prevailing market prices. These commitments range from 1 to 5 years. In certain raw material purchase contracts, we have the right to purchase less than 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 obligations shown in the table above.

(2) As a part of the May 2015 refinancing, we redeemed our existing 2019 Senior Notes, replacing those borrowings with a $500.0 million 2021 Term Loan B due November 2021, $300.0 million in USD Notes and €375.0 million in Euro Notes, both due May 2022. The Euro Notes displayed in the table above were translated using the December 31, 2015 spot exchange rate. The table above excludes other debt outstanding as of December 31, 2015 totaling $1.9 million.

(3) Includes estimated interest on the 2021 Term Loan B, USD Notes, and Euro Notes. Interest on the 2021 Term Loan B is payable quarterly. Interest on the USD Notes and Euro Notes is payable semi-annually on May 1st and November 1st of each year.For the 2021 Term Loan B, the expected interest payments included in the table above assume that the LIBO rate continues to be below the 1.00% floor as described in the Senior Credit Facility. For the Euro Notes, the expected interest payments included in the table above were translated using the December 31, 2015 spot exchange rate. Refer to Item 7A—Quantitative and Qualitative Disclosures about Market Risk for further discussion of interest rate and foreign currency risks. Estimated interest payments do not include the 2020 Revolving Facility or Accounts Receivable Securitization Facility as amounts outstanding under these facilities vary due to periodic borrowings and repayments. There are no amounts outstanding under either facility as of December 31, 2015.

(4) Includes minimum contributions required to be made to the funded pension plans and expected benefit payments to the employees for unfunded pension plans. With respect to our minimum funding requirements under our pension obligations, we may elect to make contributions in excess of the minimum funding requirements in response to investment performance or changes in interest rates or when we believe that it is financially advantageous to do so and based on our other cash requirements. Our minimum funding requirements after 2015 will depend on several factors, including investment performance and interest rates. Our minimum funding requirements may also be affected by changes in applicable legal requirements. We also have payments due with respect to our postretirement benefit obligations, which we do not fund in advance. Rather, payments are made as costs are incurred by covered retirees. We expect benefit payments related to our postretirement benefit obligations to be $3.3 million through 2025.  The payments identified above as subsequent to 2020 represent estimated pension and postretirement payments from 2021 through 2025. Also included in the above is a $13.9 million expected benefit obligation for payments estimated to be payable in 2017 under the Company’s non-qualified supplemental employee retirement plan. See Note 16 to the consolidated financial statements for further discussion.

(5) Excludes certain estimated future commitments under agreements with Dow, including a Second Amended and Restated Master Outsourcing Services Agreement (“SAR MOSA”) under which Dow provides administrative and operational services to us and 25-year site services agreements, as amended (“SSAs”) under which Dow provides utilities and site services to certain of our facilities co-located with Dow.

The services provided pursuant to the SAR MOSA generally are priced per function, and we have the ability to terminate the services or any portion thereof, for convenience any time after June 1, 2015, subject to payment of termination charges. Services which are “highly integrated” follow a different process for evaluation and termination. In addition, either party may terminate for cause, which includes a bankruptcy, liquidation or similar proceeding by the other party, for material breach which is not cured, or by Dow in the event of our failure to pay for the services thereunder. In the event of a change of control, as defined in the agreement, Dow has the right to terminate the SAR MOSA. As of December 31, 2015, we estimate our minimum obligation under the SAR MOSA to be approximately $28.2 million. However, should we continue with this contract through its completion on December 31, 2020, we estimate our minimum cumulative obligation, excluding the impacts of inflation, as of December 31, 2015 to be approximately $234.9 million.

These agreements may be terminated at any time by agreement of the parties, or, by either party, for cause, including a bankruptcy, liquidation or similar proceeding by the other party, or under certain circumstances for a material breach which is not cured. In addition, we may terminate for convenience any services that Dow has agreed to provide to us that are identified in any site services agreement as “terminable” with 12 months prior notice to Dow, dependent upon whether the service is highly integrated into Dow operations. Highly integrated services are agreed to be nonterminable. With respect to “nonterminable” services that Dow has agreed to provide to us, such as electricity and steam, we generally cannot terminate such services prior to the termination date unless we experience a production unit shut down for which we provide Dow with 15-months prior notice, or upon payment of a shutdown fee. Upon expiration or termination, we would be obligated to pay a monthly fee to Dow, which obligation extends for a period of 45 (in the case of expiration) to 60 months (in the case of termination) following the respective event of each site services agreement. The agreements under which Dow receives services from us may be terminated under the same circumstances and conditions. Utilizing current year known costs and assuming that we continue with these agreements, we estimate our contractual obligations for the SSAs to be approximately $186.1 million annually for 2016 through 2020. Should we choose to continue these agreements, we estimate our minimum cumulative obligation would be approximately $4,182.6 million through June 2038.

See Note 18 to the consolidated financial statements for further details.

(6) Due to uncertainties in the timing of the effective settlement of tax positions with the respective taxing authorities, we are unable to determine the timing of payments related to its uncertain tax positions, including interest and penalties. Amounts are therefore reflected in “Thereafter”.

Critical Accounting Policies and Estimates

Our discussion and analysis of results of operations and financial condition are based upon our financial statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the amounts reported. We base these estimates and judgments on historical experiences and assumptions believed to be reasonable under the circumstances. Actual results could vary from our estimates under different conditions. Our significant accounting policies, which may be affected by our estimates and assumptions, are more fully described in Note 2 to our consolidated financial statements. An accounting policy is deemed to be critical if it requires an accounting estimate to be made based on assumptions about matters that are highly uncertain at the time the estimate is made, and if different estimates that reasonably could have been used, or changes in the accounting estimates that are reasonably likely to occur periodically, could materially impact the financial statements. The following critical accounting policies reflect our most significant estimates and assumptions used in the preparation of the financial statements.

Pension Plans and Postretirement Benefits

We have various company-sponsored retirement plans covering substantially all employees. We also provide certain health care and life insurance benefits to retired employees mainly in the United States and Brazil. The plans provide health care benefits, including hospital, physicians’ services, drug and major medical expense coverage, and life

85

insurance benefits. We recognize the underfunded or overfunded status of a defined benefit pension or postretirement plan as an asset or liability in our balance sheet and recognize changes in the funded status in the year in which the changes occur through accumulated other comprehensive income, which is a component of shareholders’ equity.

A settlement is a transaction that is an irrevocable action that relieves the employer (or the plan) of primary responsibility for a pension or postretirement benefit obligation, and that eliminates significant risks related to the obligation and the assets used to effect the settlement. The Company does not record settlement gains or losses during interim periods when the cost of all settlements in a year is less than or equal to the sum of the service cost and interest cost components of net periodic pension cost for the plan in that year.

Pension benefits associated with these plans are generally based on each participant’s years of service, compensation, and age at retirement or termination. The discount rate is an important element of expense and liability measurement. We evaluate our assumptions at least once each year, or as facts and circumstances dictate, and make changes as conditions warrant.

We determine the discount rate used to measure plan liabilities as of the December 31 measurement date for the pension and postretirement benefit plans. The discount rate reflects the current rate at which the associated liabilities could be effectively settled at the end of the year. We set our rate to reflect the yield of a portfolio of high quality, fixed-income debt instruments that would produce cash flows sufficient in timing and amount to settle projected future benefits. Using this methodology, we determined a discount rate of 2.06% for pension and 6.51% for postretirement benefits to be appropriate as of December 31, 2015.

We determine the expected long-term rate of return on assets by performing a detailed analysis of historical and expected returns based on the underlying assets, which generally are insurance contracts. We also consider our historical experience with the pension fund asset performance. The expected return of each asset class is derived from a forecasted future return confirmed by current and historical experience. The weighted-average long-term rate of return assumption used for determining net periodic pension expense for 2015 was 1.73%, while the weighted-average long-term rate of return assumption used for determining net periodic pension expense for 2014 was 2.83%. The decrease was primarily due to lower interest rates during 2015 on certain assets with guaranteed returns. Future actual pension expense will depend on the performance of the underlying assets and changes in future discount rates, among other factors.

Holding all other factors constant, a 0.25 percentage point increase (decrease) in the discount rate used to determine net periodic cost would decrease (increase) 2015 pension expense by approximately $1.8 million and $(1.9) million, respectively. Holding all other factors constant, a 0.25 percentage point increase (decrease) in the long-term rate of return on assets used to determine net periodic cost would decrease (increase) 2015 pension expense by approximately $0.3 million and $(0.3) million, respectively.

Plan assets are invested primarily in insurance contracts that provide for guaranteed returns. As of December 31, 2015 and 2014, respectively, plan assets totaled $100.5 million and $92.6 million. Investments in the pension plan insurance are valued utilizing unobservable inputs, which are contractually determined based on cash surrender values, returns, fees, and the present value of the future cash flows of the contracts, and are classified as Level 3 investments.

Stock-Based Compensation

Restricted Stock Awards issued by the Parent

From 2010 through 2013, our Parent granted various time-based and performance-based restricted stock awards to certain key members of management. Any related compensation associated with these awards is allocated to the Company from the Parent. With the adoption of the Company’s 2014 Omnibus Plan, discussed further below, restricted stock awards will no longer be issued by the Parent on behalf of the Company.

On June 10, 2014, prior to the completion of the Company’s IPO, the Parent entered into agreements to modify the outstanding performance-based restricted stock awards held by the Company’s employees to remove the performance-based vesting condition associated with such awards related to the achievement of certain investment returns (while maintaining the requirement for a change in control or IPO).  Henceforth, these awards have been described as the Company’s modified time-based restricted stock awards. Prior to this modification, the Company had not recorded any compensation expense related to these awards as the likelihood of achieving the existing performance condition of a change in control or IPO was not deemed to be probable.

86

Compensation expense related to time-based and modified time-based restricted stock awards is equivalent to the grant-date fair value of the Parent’s ordinary shares adjusted for the return of co-investment share and other equity investment amounts, as discussed below, and is recognized as compensation expense over the service period utilizing graded vesting.

Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Stock-based compensation expense recognized in our consolidated financial statements is based on awards that are ultimately expected to vest.

The Parent has a call right that gives it the option, but not the obligation, to repurchase vested stock at the then current fair value upon an employee’s termination, or at cost in certain circumstances. During the year-ended December 31, 2013, as the result of certain employee terminations, the Parent repurchased a total of 3,372 previously vested time-based restricted stock awards at cost, resulting in a $0.9 million favorable adjustment to stock-based compensation expense. No such events occurred in 2014 or 2015.  

Our Parent is a private company with no active public market for its ordinary shares. For grants made through the third quarter of 2010, the awards were valued using a share price derived from the purchase price of the acquired assets and liabilities on that date. For grants awarded or modified from the fourth quarter of 2010 through 2014, our Parent determined the estimated per share fair value of its ordinary shares using a contemporaneous valuation consistent with the American Institute of Certified Public Accountants 2013 Guide, “Valuation of Privately-Held Company Equity Securities Issued as Compensation” (the “Guide”). In conducting this valuation, our Parent considered all objective and subjective factors that it believed to be relevant, including its best estimate of its business condition, prospects, and operating performance. Within this contemporaneous valuation, a range of factors, assumptions, and methodologies were used. The significant factors included:

· the fact that, prior to June 2014, we and our Parent were private companies with illiquid securities; since our June 2014 IPO, the Company is now publicly traded, but the Parent (from whom incentive shares are awarded) remains a private company;

· our historical operating results;

· our discounted future cash flows, based on our projected operating results;

· valuations and historical stock price volatility of comparable public companies; and

· the risk involved in the investment, as related to earnings stability, capital structure, competition and market potential.

For all contemporaneous valuations of our Parent’s ordinary shares prior to our IPO in June 2014, management estimated, as of the grant date, our enterprise value on a continuing operations basis, using the income and market approaches, as described in the Guide. The income approach utilized a discounted cash flow (“DCF”) methodology based on our financial forecasts and projections. The market approach utilized the Guideline Public Company and Guideline Transactions methods.

For the DCF methodology, we prepared annual projections of future cash flows, generally over the next 5 years, with terminal year cash flows projected at long-term sustainable growth rates consistent with long-term inflationary and industry expectations. Our projections of future cash flows were based on our estimated net debt-free cash flows and were discounted to the valuation date using a weighted-average cost of capital estimated using market participant assumptions.

For the Guideline Public Company and Guideline Transactions methods, we identified a group of comparable public companies and recent transactions within our industry. For the comparable companies, we estimated market multiples based on trading prices and trailing 12 months EBITDA and projected future EBITDA. We then calculated a rolling two year average of these multiples, which were applied to our trailing 12 months and projected EBITDA. When selecting comparable companies, consideration was given to industry similarity, their specific products offered, financial data availability and capital structure.

For the comparable transactions, we estimated market multiples based on prices paid for the related transactions and trailing 12 months EBITDA. These multiples were then applied to our trailing 12 months EBITDA. The results of the market approaches corroborated the fair value determined using the income approach.

87

For valuations performed in 2014, primarily as a result of the June modification of performance-based awards discussed above, we applied a similar valuation methodology. However, rather than developing an estimate of the business enterprise value of the Parent using the methods discussed above, we derived the fair value using the market capitalization of the Company, based on the prevailing price of the Company’s publicly-traded stock, adjusted for net debt and other factors.

There were no valuations required in 2015 as there were no grants or modifications of incentive shares issued by the Parent.

2014 Omnibus Incentive Plan

In connection with the IPO, the Company’s board of directors approved the 2014 Omnibus Plan, adopted on May 28, 2014, under which the maximum number of ordinary shares that may be delivered upon satisfaction of awards granted under such plan is 4.5 million shares. Following the IPO, all equity-based awards granted by the Company are granted under the 2014 Omnibus Plan, which provides for awards of stock options, share appreciation rights, restricted stock, unrestricted stock, stock units, performance awards, cash awards and other awards convertible into or otherwise based ordinary shares of the Company.

During 2014, a limited number of restricted share units (“RSUs”) were granted under the 2014 Omnibus Plan to two of the Company’s directors.  During 2015, the board of directors of the Company approved a more broad-based equity award grant for directors and certain executives and employees, comprised of RSUs and options to purchase shares (“option awards”).

Compensation costs for the RSUs are measured at the grant date based on the fair value of the award and are recognized ratably as expense over the applicable vesting term. The fair value of RSUs is equal to the fair market value of the Company’s ordinary shares based on the closing price on the date of grant.

Compensation cost for the option awards is measured at the grant date based on the fair value of the award and is recognized as expense over the appropriate service period utilizing graded vesting. The fair value for option awards is computed using the Black-Scholes pricing model, whose significant inputs and assumptions are determined as of the date of grant. Determining the fair value of the option awards requires considerable judgment, including estimating the expected term of stock options and the expected volatility of the price of the Company’s ordinary shares.

Since the Company’s equity interests were privately held prior to the IPO in June 2014, there is limited publicly traded history of its ordinary shares, and as a result the expected volatility used in the Black-Scholes pricing model is based on the historical volatility of similar companies’ stock that are publicly traded as well as the Company’s debt-to-equity ratio. Until such time that the Company has enough publicly traded history of its ordinary shares to determine expected volatility based solely on its ordinary shares, estimated volatility of options granted will be based on a combination of our historical volatility and similar companies’ stock that are publicly traded. The expected term of options represents the period of time that options granted are expected to be outstanding. For option awards granted to date, the simplified method was used to calculate the expected term of options, given the Company’s limited historical exercise data. The risk-free interest rate for the periods within the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The dividend yield is assumed to be zero based on historical and expected dividend activity.

Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Stock-based compensation expense recognized in our consolidated financial statements is based on awards that are ultimately expected to vest.

Asset Impairments

As of December 31, 2015, net property, plant and equipment totaled $518.8 million, net identifiable finite-lived intangible assets totaled $158.2 million and goodwill totaled $31.1 million. Management makes estimates and assumptions in preparing the financial statements for which actual results will emerge over long periods of time. This includes the recoverability of long-lived assets employed in the business. These estimates and assumptions are closely monitored by management and periodically adjusted as circumstances warrant. For instance, expected asset lives may be shortened or impairment may be recorded based on a change in the expected use of the asset or performance of the related asset group.

88

We evaluate long-lived assets and identifiable finite-lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset grouping may not be recoverable. When undiscounted future cash flows are not expected to be sufficient to recover an asset’s carrying value, the asset is written down to its fair value based on a discounted cash flow analysis utilizing market participant assumptions.

During the three months ended December 31, 2013, we determined that the long-lived assets at our polycarbonate manufacturing facility in Stade, Germany should be assessed for impairment driven primarily by continued losses experienced in our polycarbonate business. This assessment indicated that the carrying amount of the long-lived assets at this facility were not recoverable when compared to the expected undiscounted cash flows of our polycarbonate business. Based upon our assessment of fair value of this asset group, we fully impaired these assets as of December 31, 2013. The fair value of the asset group was determined under the income approach utilizing a discounted cash flow (“DCF”) model. The key assumptions used in the DCF model included growth rates and cash flow projections, discount rate, tax rate and an estimated terminal value.

As a result, in the year ended December 31, 2013, we recorded an impairment loss of approximately $9.2 million. The amount was recorded within “Selling, general and administrative expenses” in the consolidated statement of operations and was allocated entirely to the Basic Plastics & Feedstocks segment.

Through December 31, 2015, we have continued to assess the recoverability of certain assets, and concluded there are no events or circumstances identified by management that would indicate these assets are not recoverable. However, the current environment is subject to changing market conditions and requires significant management judgment to identify the potential impact to our assessment. If we are not able to achieve certain actions or our future operating results do not meet our expectations, it is possible that impairment charges may need to be recorded on one or more of our operating facilities.

Long-lived assets to be disposed of by sale are classified as held-for-sale and are reported at the lower of carrying amount or fair value less cost to sell, and depreciation is ceased. Long-lived assets to be disposed of in a manner other than by sale are classified as held-and-used until they are disposed.

Our goodwill impairment testing is performed annually as of October 1st at a reporting unit level. We perform more frequent impairment tests when events or changes in circumstances indicate that the fair value of a reporting unit has more likely than not declined below its carrying value. As of our annual assessment date of October 1, 2015, each of our reporting units had fair values that substantially exceeded the carrying value of their net assets, indicating that no impairment of goodwill is warranted.

An impairment loss generally would be recognized when the carrying amount of the reporting unit’s net assets exceeds the estimated fair value of the reporting unit. The estimated fair value of a reporting unit is determined using a market approach and an income approach (under the discounted cash flow method). As of December 31, 2015, our $31.1 million in total goodwill is allocated as follows to our reportable segments: $12.4 million to Latex, $8.5 million to Synthetic Rubber, $2.9 million to Performance Plastics and $7.3 million to Basic Plastics & Feedstocks.

Factors which could result in future impairment charges, among others, include changes in worldwide economic conditions, changes in technology, changes in competitive conditions and customer preferences, and fluctuations in foreign currency exchange rates. These factors are discussed in Item 7A—Quantitative and Qualitative Disclosures about Market Risk and Item 1A- Risk Factors included in this Annual Report.

Income Taxes

We account for income taxes using the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences of temporary differences between the carrying amounts and tax bases of assets and liabilities using enacted rates. The effect of a change in tax rates on deferred taxes is recognized in income in the period that includes the enactment date. Deferred taxes are provided on the outside basis differences and unremitted earnings of subsidiaries outside of Luxembourg. All undistributed earnings of foreign subsidiaries and affiliates are expected to be repatriated as of December 31, 2015. Based on the evaluation of available evidence, both positive and negative, we recognize future tax benefits, such as net operating loss carryforwards and tax credit carryforwards, to the extent that realizing these benefits is considered to be more likely than not.  

As of December 31, 2015, we had a net deferred tax asset balance of $25.6 million, after valuation allowances of $85.1 million. With the adoption of new guidance from the FASB as of December 31, 2015, for each tax jurisdiction in

89

which the Company operates, deferred tax assets and liabilities are offset against one another and are presented as a single noncurrent amount within the consolidated balance sheets.  See Note 2 to the consolidated financial statements for further discussion of the impact of adopting this guidance.

In evaluating the ability to realize the deferred tax assets, we rely on, in order of increasing subjectivity, taxable income in prior carryback years, the future reversals of existing taxable temporary differences, tax planning strategies and forecasted taxable income using historical and projected future operating results.  

As of December 31, 2015, we had deferred tax assets for tax loss carryforward of approximately $263.9 million, $37.5 million of which is subject to expiration in the years between 2016 and 2020. We continue to evaluate our historical and projected operating results for several legal entities for which we maintain valuation allowances on net deferred tax assets.  

We are subject to income taxes in Luxembourg, the United States and numerous foreign jurisdictions, and are subject to audit within these jurisdictions. Therefore, in the ordinary course of business there is inherent uncertainty in quantifying our income tax positions. The tax provision includes amounts considered sufficient to pay assessments that may result from examinations of prior year tax returns; however, the amount ultimately paid upon resolution of issues raised may differ from the amounts accrued. Since significant judgment is required to assess the future tax consequences of events that have been recognized in our financial statements or tax returns, the ultimate resolution of these events could result in adjustments to our financial statements and such adjustments could be material. Therefore, we consider such estimates to be critical in preparation of our financial statements.  

The financial statement effect of an uncertain income tax position is recognized when it is more likely than not, based on the technical merits, that the position will be sustained upon examination. Accruals are recorded for other tax contingencies when it is probable that a liability to a taxing authority has been incurred and the amount of the contingency can be reasonably estimated. Uncertain income tax positions have been recorded in “Other noncurrent obligations” in the consolidated balance sheets for the periods presented.  

Management judgment is required in determining our provision for income taxes, our deferred tax assets and liabilities, and any valuation allowance recorded against our deferred tax assets. The valuation allowance is based on our estimates of future taxable income and the period over which we expect the deferred tax assets to be recovered. Our assessment of future taxable income is based on historical experience and current and anticipated market and economic conditions and trends. In the event that actual results differ from these estimates or we adjust our estimates in the future, we may need to adjust our valuation allowance, which could materially impact our financial position and results of operations.

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 the consolidated financial statements, included elsewhere within this Annual Report.

Item 7A.    Quantitative and Qualitative Disclosures About Market Risk

We are exposed to changes in interest rates and foreign currency exchange rates because we finance certain operations through fixed and variable rate debt instruments and denominate our transactions in a variety of foreign currencies. We are also exposed to changes in the prices of certain commodities that we use in production. Changes in these rates and commodity prices may have an impact on future cash flow and earnings. We manage these risks through normal operating and financing activities and, when deemed appropriate, through the use of derivative financial instruments. We do not enter into financial instruments for trading or speculative purposes.

By using derivative instruments, we are subject to credit and market risk. The fair market value of the derivative instruments is determined by using valuation models whose inputs are derived using market observable inputs, including

90

interest rate yield curves, as well as foreign exchange and commodity spot and forward rates, and reflects the asset or liability position as of the end of each reporting period. When the fair value of a derivative contract is positive, the counterparty owes us, thus creating a receivable risk for us. We are exposed to counterparty credit risk in the event of non-performance by counterparties to our derivative agreements. We minimize counterparty credit (or repayment) risk by entering into transactions with major financial institutions of investment grade credit rating.

Our exposure to market risk is not hedged in a manner that completely eliminates the effects of changing market conditions on earnings or cash flow.

Interest Rate Risk

Given the leveraged nature of our Company, we have exposure to changes in interest rates. During 2013, we had borrowings under the 2018 Revolving Facility, on which we incurred interest charges subject to the rates discussed above. Based on the weighted-average outstanding borrowings under the 2018 Revolving Facility throughout the year ended December 31, 2013, an increase of 100 basis points in the LIBO rate would have resulted in approximately $0.2 million of additional interest expense for the period. As of and throughout the year ended December 31, 2014, we had no variable rate debt issued under our 2018 Senior Secured Credit Facility, including no amounts outstanding under the 2018 Revolving Facility. As such, we incurred no variable rate interest related to this facility during the year ended December 31, 2014. This remained true until the 2018 Senior Secured Credit Facility was terminated in conjunction with the May 2015 debt refinancing.

On May 5, 2015, the Borrowers, entered into the Credit Agreement, which provides senior secured financing of up to $825.0 million, defined as the Senior Credit Facility.  The Senior Credit Facility provides for senior secured financing consisting of the (i) 2020 Revolving Facility including a $325.0 revolving credit facility, with a $25.0 million swingline subfacility and a $35.0 million letter of credit subfacility maturing in May 2020 and (ii) $500.0 million senior secured 2021 Term Loan B. Amounts under the 2020 Revolving Facility are available in U.S. dollars and euros.

The 2021 Term Loan B bears an interest rate of LIBOR plus 3.25%, subject to a 1.00% LIBOR floor, and was issued at a 0.25% original issue discount.  Further, the 2021 Term Loan B requires scheduled quarterly payments in amounts equal to 0.25% of the original principal amount of the 2021 Term Loan B, with the balance to be paid at maturity. Based on weighted-average outstanding borrowings under the 2021 Term Loan B throughout the year ended December 31, 2015, an increase in 100 basis points in the LIBO rate would have resulted in approximately $1.1 million of additional interest expense for the period.

Loans under the 2020 Revolving Facility, at the Borrowers’ option, may be maintained as (a) LIBO rate loans, which bear interest at a rate per annum equal to the LIBO rate plus the applicable margin (as defined in the Credit Agreement), if applicable, or (b) base rate loans which shall bear interest at a rate per annum equal to the base rate plus the applicable margin (as defined in the Credit Agreement).  As of December 31, 2015, the Borrowers will be required to pay a quarterly commitment fee in respect of any unused commitments under the 2020 Revolving Facility equal to 0.375% per annum. As of and throughout the year ended December 31, 2015, we had no variable rate debt issued under our 2020 Revolving Facility. As such, we incurred no variable rate interest related to this facility during the year ended December 31, 2015.

The USD Notes and Euro Notes issued in May 2015 carry a fixed interest rate of 6.750% and 6.375%, respectively.

Our Accounts Receivable Securitization Facility is subject to interest charges against both the amount of outstanding borrowings as well as the amount of available, but undrawn commitments under the Accounts Receivable Securitization Facility. In regards to outstanding borrowings on the Accounts Receivable Securitization Facility, fixed interest charges are 2.6% plus variable commercial paper rates which vary by month and by currency as outstanding Account Receivable Securitization Facility balances can be denominated in euro and U.S. dollar. In regards to available, but undrawn commitments under the Accounts Receivable Securitization Facility, fixed interest charges are 1.4%. Due to our limited use of this facility during the year ended December 31, 2015, an increase of 100 basis points in variable commercial paper rates would have resulted in less than $0.1 million of additional interest expense for the period based on weighted-average outstanding borrowings. As of December 31, 2015, there were no outstanding borrowings and there was $123.4 million of funds available for borrowing under the Accounts Receivable Securitization Facility.

Foreign Currency Risks

The Company’s ongoing business operations expose it to foreign currency risks, including fluctuating foreign exchange rates. Our foreign currency exposures include the euro, Swiss franc, Chinese yuan, Indonesian rupiah, British pound, Japanese yen, Brazilian real and Swedish krona. The primary foreign currency exposure relates to the U.S. dollar to euro exchange rate. To manage these risks, the Company periodically enters into derivative financial instruments such as foreign exchange forward contracts.

Certain subsidiaries have assets and liabilities denominated in currencies other than their respective functional currencies, which creates foreign exchange risk. Our principal strategy in managing 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 our exposure, we also use 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.

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 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.

We have legal entities consolidated in our financial statements that have functional currencies other than U.S. dollar, our reporting currency. As a result of currencies fluctuating against the U.S. dollar, currency translation gains and losses are recorded in other comprehensive income, primarily as a result of the remeasurement of our euro functional legal entities as of December 31, 2015 and 2014.

Commodity Price Risk

We purchase certain raw materials such as benzene, ethylene, butadiene, BPA and styrene under short- and long-term supply contracts. The purchase prices are generally determined based on prevailing market conditions. Changing raw material and energy prices have had material impacts on our earnings and cash flows in the past and will likely continue to have significant impacts on our earnings and cash flows in future periods. We do not currently enter into derivative financial instruments for trading or speculative purposes to manage our commodity price risk relating to our raw material contracts.

Management’s Annual Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of the Company’s financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with policies and procedures may deteriorate.

Management conducted an assessment of the Company’s internal control over financial reporting as of December 31, 2015 based on the framework in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on the assessment, management concluded that, as of December 31, 2015, the Company’s internal control over financial reporting is effective.

The effectiveness of the Company’s internal control over financial reporting as of December 31, 2015 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears herein.

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 year ended December 31, 2015 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of Trinseo S.A.:

In our opinion, based on our audits and the report of other auditors, the accompanying consolidated balance sheets and the related consolidated statements of operations, of comprehensive income (loss), of shareholders’ equity and of cash flows present fairly, in all material respects, the financial position of Trinseo S.A. and its subsidiaries as of December 31, 2015 and December 31, 2014, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2015 in conformity with accounting principles generally accepted in the United States of America.  In addition, in our opinion, the financial statement schedule listed in the accompanying index presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control - Integrated Framework (2013)issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).  The Company's management is responsible for these financial statements and financial statement schedule, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management's Annual Report on Internal Control over Financial Reporting appearing under Item 9A.  Our responsibility is to express opinions on these financial statements, the financial statement schedule, and on the Company's internal control over financial reporting based on our audits (which was an integrated audit in 2015).We did not audit the financial statements of Americas Styrenics LLC, a 50-percent-owned equity investment of Trinseo S.A. as of or for the year ended December 31, 2015. Trinseo S.A.’s consolidated financial statements reflect an investment in unconsolidated affiliates for Americas Styrenics LLC of $143.9 million as of December 31, 2015 and includes equity in the earnings of unconsolidated affiliates for Americas Styrenics LLC of $135.3 million for the year ended December 31, 2015. The financial statements of Americas Styrenics LLC were audited by other auditors whose report thereon has been furnished to us, and our opinion on the December 31, 2015 consolidated financial statements expressed herein, insofar as it relates to the amounts included for Americas Styrenics LLC, is based solely on the report of other auditors. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States).  Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects.  Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation.  Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk.  Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits and the report of other auditors provide a reasonable basis for our opinions.

As discussed in Note 2 to the consolidated financial statements, the Company changed the manner in which it classifies deferred income taxes in 2015.

A  company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.  A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.  Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

TRINSEO S.A.

Notes to Consolidated Financial Statements

(Dollars in thousands, unless otherwise stated)

NOTE 1—ORGANIZATION AND BUSINESS ACTIVITIES

Organization

On June 3, 2010, Bain Capital Everest Manager Holding SCA (the “Parent”), an affiliate of Bain Capital Partners, LP (“Bain Capital”), was formed through investment funds advised or managed by Bain Capital. Dow Europe Holding B.V. (together with The Dow Chemical Company, “Dow”) retained an indirect ownership interest in the Parent. Trinseo S.A. (“Trinseo”, and together with its subsidiaries, the “Company”) was also formed on June 3, 2010, incorporated under the existing laws of the Grand Duchy of Luxembourg. At that time, all ordinary shares of Trinseo were owned by the Parent. On June 17, 2010, Trinseo acquired 100% of the former Styron business from Dow (the “Acquisition”), at which time, the Company commenced operations.

On May 30, 2014, the Company amended its Articles of Association to effect a 1-for-436.69219 reverse split of its issued and outstanding ordinary shares (“reverse split”) and to increase its authorized shares to 50.0 billion. All share and per share data were retroactively adjusted in the accompanying financial statements to give effect to the reverse split.

On June 17, 2014, Trinseo completed an initial public offering (the “IPO”) of 11,500,000 ordinary shares at a price of $19.00 per share, which included 1,500,000 shares sold pursuant to the underwriters’ exercise of their over-allotment option. The Company received cash proceeds of $203.2 million from this transaction, net of underwriting discounts. See Note 12 for more information.

Business Activities

The Company is a leading global materials company engaged in the manufacturing and marketing of synthetic rubber, latex, and plastics, including various specialty and technologically differentiated products. The Company develops emulsion polymers and plastics products that are incorporated into a wide range of products throughout the world, including tires and other products for automotive applications, carpet and artificial turf backing, coated paper and packaging board, food service packaging, appliances, medical devices, consumer electronics and construction applications, among others.

The Company’s operations are located in Europe and the Middle East, North America, Latin America, and Asia Pacific, supplemented by two strategic joint ventures, Americas Styrenics LLC (“Americas Styrenics”), a polystyrene joint venture with Chevron Phillips Chemical Company LP, and Sumika Styron Polycarbonate Limited (“Sumika Styron Polycarbonate”).

NOTE 2—BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation and Principles of Consolidation

The accompanying consolidated financial statements as of December 31, 2015 and 2014 and for each of the three years in the period ended December 31, 2015 are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The consolidated financial statements of the Company contain the accounts of all entities that are controlled and variable interest entities (“VIEs”) for which the Company is the primary

F-8

beneficiary. A VIE is defined as a legal entity that has equity investors that do not have sufficient equity at risk for the entity to support its activities without additional subordinated financial support or, as a group, the holders of the equity at risk lack (i) the power to direct the entity’s activities or (ii) the obligation to absorb the expected losses or the right to receive the expected residual returns of the entity. A VIE is required to be consolidated by a company if that company is the primary beneficiary. Refer to Note 10 for further discussion of the Company’s accounts receivable securitization facility, which qualifies as a VIE and is consolidated within the Company’s financial statements.

All intercompany balances and transactions are eliminated. Joint ventures over which the Company has the ability to exercise significant influence that are not consolidated are accounted for by the equity method.

Use of Estimates in Financial Statement Preparation

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual amounts could differ from these estimates.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash equivalents and accounts receivables. The Company uses major financial institutions with high credit ratings to engage in transactions involving cash equivalents. The Company minimizes credit risk in its receivables by selling products to a diversified portfolio of customers in a variety of markets located throughout the world.

The Company performs ongoing evaluations of its customers’ credit and generally does not require collateral. The Company maintains an allowance for doubtful accounts for losses resulting from the inability of specific customers to meet their financial obligations, representing our best estimate of probable credit losses in existing trade accounts receivable. A specific reserve for doubtful receivables is recorded against the amount due from these customers. For all other customers, the Company recognizes reserves for doubtful receivables based on historical experience.

Financial Instruments

The carrying amounts of the Company’s financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and accrued and other current liabilities, approximate fair value due to their generally short maturities.

The estimated fair value of the Company’s 2021 Term Loan B, 2022 Senior Notes, and 2019 Senior Notes (all of which are defined in Note 10) are determined using level 2 inputs within the fair value hierarchy. Refer to Note 13 for the fair value of these debt instruments. When outstanding, the estimated fair values of borrowings under the Company’s 2020 Revolving Facility and Accounts Receivable Securitization Facility (both of which are defined in Note 10) are determined using level 2 inputs within the fair value hierarchy. The carrying amounts of borrowings under the 2020 Revolving Facility and Accounts Receivable Securitization Facility approximate fair value as these borrowings bear interest based on prevailing variable market rates.

At times, the Company manages its exposure to changes in foreign currency exchange rates, where possible, by entering into foreign exchange forward contracts. When outstanding, all derivatives, whether designated in hedging relationships or not, are required to be recorded on the balance sheet at fair value. The fair value of the derivatives is determined from sources independent of the Company, including the financial institutions which are party to the derivative instruments. The fair value of derivatives also considers the credit default risk of the paying party. If the derivative is designated as a fair value hedge, the changes in the fair value of the derivative and the hedged item will be recognized in earnings. If the derivative is designated as a cash flow hedge, the effective portion of the change in the fair value of the derivative will be recorded in other comprehensive income and will be recognized in the consolidated statements of operations when the hedged item affects earnings.

As of December 31, 2015 and 2014, the Company had certain foreign exchange forward contracts outstanding that were not designated for hedge accounting treatment. As such, the settlements and changes in fair value of underlying instruments are recognized in “Other expense, net” in the consolidated statements of operations. For the years ended

F-9

December 31, 2015, 2014, and 2013, the Company recognized losses related to these forward contracts of $16.5 million, $28.2 million, and $0.6 million, respectively.

As of December 31, 2015, the Company also had foreign exchange forward contracts which are designated as cash flow hedges. As such, 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 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. No such contracts were outstanding as of December 31, 2014.

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. The Company records these foreign exchange forward contracts on a net basis, by counterparty within the consolidated balance sheets.

The Company presents the cash receipts and payments from hedging activities in the same category as the cash flows from the items subject to hedging relationships. As the items subject to economic hedging relationships are the Company’s operating assets and liabilities, the related cash flows are classified within operating activities in the consolidated statements of cash flows.

Foreign Currency Translation

For the majority of the Company’s subsidiaries, the local currency has been identified as the functional currency. For remaining subsidiaries, the U.S. dollar has been identified as the functional currency due to the significant influence of the U.S. dollar on their operations. Gains and losses resulting from the translation of various functional currencies into U.S. dollars are not recorded within the consolidated statements of operations. Rather, they are recorded within the cumulative translation adjustment account as a separate component of shareholders’ equity (accumulated other comprehensive income) on the consolidated balance sheets. The Company translates asset and liability balances at exchange rates in effect at the end of the period and income and expense transactions at the average exchange rates in effect during the period. Gains and losses resulting from foreign currency transactions are recorded within the consolidated statements of operations.

For the year ended December 31, 2015 and 2014, the Company recognized net foreign exchange transaction gains of $6.1 million and $32.4 million, respectively. For the year ended December 31, 2013, the Company recognized net foreign exchange transaction losses of $18.3 million. These amounts exclude the impacts of foreign exchange forward contracts discussed above. Gains and losses on net foreign exchange transactions are recorded within “Other expense, net” in the consolidated statements of operations.

Environmental Matters

Accruals for environmental matters are recorded when it is considered probable that a liability has been incurred and the amount of the liability can be reasonably estimated, based on current law and existing technologies. These accruals are adjusted periodically as assessment and remediation efforts progress, or as additional technical or legal information become available. Accruals for environmental liabilities are recorded within “Other noncurrent obligations” in the consolidated balance sheets at undiscounted amounts. As of December 31, 2015 and 2014, there were no accruals for environmental liabilities recorded.

Environmental costs are capitalized if the costs extend the life of the property, increase its capacity, or mitigate or prevent contamination from future operations. Environmental costs are also capitalized in recognition of legal asset retirement obligations resulting from the acquisition, construction or normal operation of a long-lived asset. Any costs related to environmental contamination treatment and clean-ups are charged to expense. Estimated future incremental operations, maintenance and management costs directly related to remediation are accrued when such costs are probable and reasonably estimable.

F-10

Cash and Cash Equivalents

Cash and cash equivalents generally include time deposits or highly liquid investments with original maturities of three months or less.

Inventories

Inventories are stated at the lower of cost or market, with cost being determined on the first-in, first-out (“FIFO”) method. The Company periodically reviews its inventory for excess or obsolete inventory, and will write-down the excess or obsolete inventory value to its net realizable value, if applicable.

Property, Plant and Equipment

Property, plant and equipment are carried at cost less accumulated depreciation and less impairment, if applicable, and are depreciated over their estimated useful lives using the straight-line method. Capitalized costs associated with computer software for internal use are amortized on a straight-line basis over their estimated useful life.

Expenditures for maintenance and repairs are charged against income as incurred. Expenditures that significantly increase asset value, extend useful asset lives or adapt property to a new or different use are capitalized. These expenditures include planned major maintenance activity or turnaround activities that increase our manufacturing plants’ output and improve production efficiency as compared to pre-turnaround operations. As of December 31, 2015 and 2014, $7.6 million and $9.2 million, respectively, of the Company’s net costs related to turnaround activities were capitalized within “Deferred charges and other assets” in the consolidated balance sheets, and are being amortized over the period until the next scheduled turnaround.

The Company periodically evaluates actual experience to determine whether events and circumstances have occurred that may warrant revision of the estimated useful lives of property, plant and equipment. Engineering and other costs directly related to the construction of property, plant and equipment are capitalized as construction in progress until construction is complete and such property, plant and equipment is ready and available to perform its specifically assigned function. Upon retirement or other disposal, the asset cost and related accumulated depreciation are removed from the accounts and the net amount, less any proceeds, is charged or credited to income. The Company also capitalizes interest as a component of the cost of capital assets constructed for its own use.

Impairment and Disposal of Long-Lived Assets

The Company evaluates long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. When undiscounted future cash flows are not expected to be sufficient to recover an asset’s carrying amount, the asset is written down to its fair value based on a discounted cash flow analysis utilizing market participant assumptions.

Long-lived assets to be disposed of by sale are classified as held-for-sale and are reported at the lower of carrying amount or fair value less cost to sell, and depreciation is ceased. Long-lived assets to be disposed of in a manner other than by sale are classified as held-and-used until they are disposed.

Goodwill and Other Intangible Assets

The Company records goodwill when the purchase price of a business acquisition exceeds the estimated fair value of net identified tangible and intangible assets acquired. Goodwill is tested for impairment at the reporting unit level annually, or more frequently when events or changes in circumstances indicate that the fair value of a reporting unit has more likely than not declined below its carrying value. The Company utilizes a market approach and an income approach (under the discounted cash flow method) to calculate the fair value of its reporting units. The annual impairment assessment is completed using a measurement date of October 1st.  No goodwill impairment losses were recorded in the years ended December 31, 2015, 2014 and 2013.

Finite-lived intangible assets, such as our intellectual property and manufacturing capacity rights, are amortized on a straight-line basis and are reviewed for impairment or obsolescence if events or changes in circumstances indicate that

F-11

their carrying amount may not be recoverable. If impaired, intangible assets are written down to fair value based on discounted cash flows. No intangible asset impairment losses were recorded in the years ended December 31, 2015, 2014 and 2013.

Deferred Financing Fees

Capitalized fees and costs incurred in connection with the Company’s financing arrangements are recorded in “Deferred charges and other assets” within the consolidated balance sheets. For the 2021 Term Loan B and 2022 Senior Notes (and the 2019 Senior Notes, prior to their repayment in May 2015), deferred financing fees are amortized over the term of the agreement using the effective interest method, while for the 2020 Revolving Facility and the Accounts Receivable Securitization Facility, deferred financing fees are amortized using the straight-line method over the term of the respective facility. Amortization of deferred financing fees is recorded in “Interest expense, net” within the consolidated statements of operations.

Investments in Unconsolidated Affiliates

Investments in unconsolidated affiliates in which the Company has the ability to exercise significant influence (generally, 20% to 50% owned companies) are accounted for using the equity method. Investments are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount of the investment may not be recoverable. An impairment loss is recorded whenever a decline in fair value of an investment in an unconsolidated affiliate below its carrying amount is determined to be other-than-temporary.

Sales

Sales are recognized when the revenue is realized or realizable and the earnings process is complete, which occurs when risk and title to the product transfers to the customer, typically at the time shipment is made. As such, title to the product generally passes when the product is delivered to the freight carrier. Standard terms of delivery are included in contracts of sale, order confirmation documents and invoices. Freight costs and any directly related costs of transporting finished product to customers are recorded as “Cost of sales” in the consolidated statements of operations. Taxes on sales are excluded from net sales.

Sales are recorded net of estimates for returns and price allowances, including discounts for prompt payment and volume-based incentives.

Cost of Sales

The Company classifies the costs of manufacturing and distributing its products as cost of sales. Manufacturing costs include raw materials, utilities, packaging and fixed manufacturing costs associated with production. Fixed manufacturing costs include such items as plant site operating costs and overhead, production planning, depreciation and amortization, repairs and maintenance, environmental, and engineering costs. Distribution costs include shipping and handling costs.

Selling, General and Administrative Expenses

Selling, general and administrative (“SG&A”) expenses are charged to expense as incurred. SG&A expenses are the cost of services performed by the marketing and sales functions (including sales managers, field sellers, marketing research, marketing communications and promotion and advertising materials) and by administrative functions (including product management, R&D, business management, customer invoicing, and human resources). R&D expenses include the cost of services performed by the R&D function, including technical service and development, process research including pilot plant operations, and product development.

Total R&D costs included in SG&A expenses were approximately $51.9 million, $53.4 million and $49.7 million for the years ended December 31, 2015, 2014 and 2013, respectively.

F-12

The Company expenses promotional and advertising costs as incurred to SG&A expenses. Total promotional and advertising expenses were approximately $3.5 million, $2.9 million and $3.0 million for the years ended December 31, 2015, 2014 and 2013, respectively.

Pension and Postretirement Benefits Plans

The Company has several defined benefit plans, under which participants earn a retirement benefit based upon a formula set forth in the plan. The Company also provides certain health care and life insurance benefits to retired employees mainly in the United States and Brazil. The plans provide health care benefits, including hospital, physicians’ services, drug and major medical expense coverage, and life insurance benefits.

Accounting for defined benefit pension plans and other postretirement benefit plans, and any curtailments and settlements thereof, requires various assumptions, including, but not limited to, discount rates, expected rates of return on plan assets and future compensation growth rates. The Company evaluates these assumptions at least once each year, or as facts and circumstances dictate, and makes changes as conditions warrant.

A settlement is a transaction that is an irrevocable action that relieves the employer (or the plan) of primary responsibility for a pension or postretirement benefit obligation, and that eliminates significant risks related to the obligation and the assets used to effect the settlement. When a settlement occurs, the Company does not record settlement gains or losses during interim periods when the cost of all settlements in a year is less than or equal to the sum of the service cost and interest cost components of net periodic pension cost for the plan in that year.

Income Taxes

The provision for income taxes is determined using the asset and liability approach of accounting for income taxes. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from differences between the financial and tax basis of the Company’s assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. With the adoption of new guidance from the Financial Accounting Standards Board (“FASB”) as of December 31, 2015, for each tax jurisdiction in which the Company operates, deferred tax assets and liabilities are offset against one another and are presented as a single noncurrent amount within the consolidated balance sheets.  See “- Recent Accounting Guidance” below for further discussion of the impact of adopting this guidance.

Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. Provision has been made for income taxes on unremitted earnings of subsidiaries and affiliates, except for subsidiaries in which earnings are deemed to be indefinitely invested.

The Company recognizes the financial statement effects of uncertain income tax positions when it is more likely than not, based on the technical merits, that the position will be sustained upon examination. The Company accrues for other tax contingencies when it is probable that a liability to a taxing authority has been incurred and the amount of the contingency can be reasonably estimated. Interest accrued related to unrecognized tax and income tax related penalties are included in the provision for income taxes. The current portion of uncertain income taxes positions is recorded in “Income taxes payable” while the long-term portion is recorded in “Other noncurrent obligations” in the consolidated balance sheets.

Stock-based Compensation

Refer to Note 17 to the consolidated financial statements for detailed discussion regarding the Company’s stock-based compensation award programs.  The following provides a brief summary of the key accounting policy elections related to these awards.

On all awards, forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Stock-based compensation expense recognized in our consolidated financial statements is based on awards that are ultimately expected to vest.

F-13

Restricted Stock Awards issued by the Parent

From 2010 through 2013, our Parent granted various time-based and performance-based restricted stock awards to certain key members of management. Any related compensation associated with these awards is allocated to the Company from the Parent.

Stock-based compensation expense for these awards is measured at the grant date, based on the fair value of the award. Time-based and modified time-based restricted stock awards are generally recognized as expense on a graded vesting basis over the related service period. Prior to their modification in June 2014, the Company recognized compensation cost related to performance-based restricted stock awards if and when it was deemed probable that the related performance condition would be achieved. When applicable, the Company calculated the fair value of its performance-based restricted stock awards using a combination of a call option and digital option model.

2014 Omnibus Incentive Plan

In connection with the IPO, the Company’s board of directors approved the 2014 Omnibus Plan. Since that time, certain equity grants have been awarded, comprised of RSUs and options awards (defined in Note 17 to the consolidated financial statements).

Compensation costs for the RSUs are measured at the grant date based on the fair value of the award and are recognized ratably as expense over the applicable vesting term. The fair value of RSUs is equal to the fair market value of the Company’s ordinary shares based on the closing price on the date of grant.

Compensation cost for the option awards is measured at the grant date based on the fair value of the award and is recognized as expense over the appropriate service period utilizing graded vesting. The fair value for option awards is computed using the Black-Scholes pricing model, whose inputs and assumptions are determined as of the date of grant.

Recent Accounting Guidance

In April 2014, the FASB issued amendments to guidance for reporting discontinued operations and disposals of components of an entity. The amended guidance requires that a disposal representing a strategic shift that has (or will have) a major effect on an entity’s financial results or a business activity classified as held-for-sale should be reported as discontinued operations. The amendments also expand the disclosure requirements for discontinued operations and add new disclosures for individually significant dispositions that do not qualify as discontinued operations. The Company adopted this guidance effective January 1, 2015, and the adoption did not have a significant impact on the Company’s financial position, results of operations, or disclosures.

In May 2014, the FASB and the International Accounting Standards Board (“IASB”) jointly issued new 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. This guidance is effective for public entities for annual and interim periods beginning after December 15, 2017. The Company is currently assessing the impact of adopting this guidance on its financial statements and results of operations.

In January 2015, the FASB issued guidance to simplify income statement classification by removing the concept of extraordinary items from GAAP. The Company adopted this guidance effective January 1, 2015 and the adoption did not have an impact on the Company’s financial position or results of operations.

In April 2015, the FASB issued guidance that requires deferred financing fees related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying value of that debt liability, consistent with debt discounts. The recognition and measurement guidance for deferred financing fees are not affected. This new guidance, which is to be applied on a retrospective basis, is effective for public companies for annual and interim periods beginning after December 15, 2015, with early adoption permitted. The Company will adopt this guidance effective January 1, 2016.  As of December 31, 2015, the Company had $32.7 million of unamortized deferred financing fees classified as noncurrent assets within “Deferred charges and other assets” on the consolidated balance sheet, of which approximately $25.7 million will be reclassified as a reduction of “Long-term debt” on the consolidated balance sheet upon adoption.

F-14

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. This pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2016, and prospective adoption is required. The Company is currently assessing the impact of adopting this guidance on its financial position and results of operations.

In November 2015, the FASB issued guidance which requires that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. This guidance is effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods, and may be applied either prospectively or retrospectively, with early adoption permitted. The Company adopted this guidance effective December 31, 2015 on a prospective basis, noting that prior periods were not retrospectively adjusted. If the Company had retrospectively adopted this guidance, $11.8 million and $1.4 million of current deferred tax assets and liabilities, respectively, would have been reclassified, resulting in a total of $57.1 million and $27.2 million of noncurrent deferred tax assets and liabilities, respectively, on the consolidated balance sheet as of December 31, 2014.

NOTE 3—ACQUISITIONS AND DIVESTITURES

The Acquisition

The Company accounted for the Acquisition (as discussed in Note 1) under the purchase method of accounting, whereby the purchase price paid, net of working capital adjustments, was allocated to the acquired assets and liabilities at fair value. As of June 17, 2011, the one-year measurement period surrounding the Acquisition ended. During 2014, an adjustment was identified related to one of our postretirement benefit plans, which dated back to the initial Acquisition accounting. As such, the Company recorded a $1.7 million increase to goodwill to correct our final purchase price allocation, with the offset recorded to postretirement benefit liabilities. The Company does not believe this adjustment was material to our prior period financial statements. Refer to Note 16 for further discussion.

As part of the Acquisition, the Company has been indemnified for various tax matters, including income tax and value add taxes, as well as legal liabilities which have been incurred prior to the Acquisition. Conversely, certain tax matters which the Company has benefitted from are subject to reimbursement by Trinseo to Dow. These amounts have been estimated and provisional amounts have been recorded based on the information known during the measurement period; however, these amounts remain subject to change based on the completion of our annual statutory filings, tax authority review as well as a final resolution with Dow on amounts due to and due from the Company. Management believes the Company’s estimates and assumptions are reasonable under the circumstances, however, settlement negotiations or changes in estimates around pre-acquisition indemnifications could result in a material impact on the consolidated financial statements.

During 2013, the Company received $6.7 million, net of tax indemnity from Dow for income taxes paid to the taxing authorities relating to the period prior to the Acquisition. This indemnity amount was previously recorded within “Accounts receivable, net of allowance” in the consolidated balance sheets. There were no other significant indemnity payments received from Dow or indemnity payments to Dow during the years ended December 31, 2015, 2014, and 2013, respectively.

Divestiture of Expandable Polystyrene Business

In June 2013, the Company’s board of directors approved the sale of its expandable polystyrene (“EPS”) business within the Company’s Basic Plastics & Feedstocks segment, under a sale and purchase agreement which was signed in July 2013. The sale closed on September 30, 2013 and the Company received $15.2 million of sales proceeds during the third quarter of 2013, subject to a $0.7 million working capital adjustment which was paid by the Company during the first quarter of 2014 and is reflected within investing activities in the consolidated statement of cash flows for the year ended December 31, 2014. The Company recognized a loss from the sale of $4.2 million recorded in “Other expense,

F-15

net” in the consolidated statement of operations for the year ended December 31, 2013. The loss calculation is as follows:

Assets
Inventories	$	8,135
Property, plant and equipment, net		9,401
Other intangibles assets, net		1,624
Goodwill		383
Total assets sold	$	19,543
Liabilities
Pension and other benefits	$	791
Total liabilities sold	$	791
Net assets sold	$	18,752
Sales proceeds, net of amount paid to buyer of $0.7 million		14,566
Loss on sale	$	4,186

EPS business results of operations were not classified as discontinued operations as the Company will have significant continuing cash flows as a result of a long-term supply agreement of styrene monomer to the EPS business, which was entered into contemporaneously with the sale and purchase agreement.

Further, under the terms of the sale and purchase agreement, should the divested EPS business record EBITDA (as defined therein) greater than zero for fiscal year 2014, the Company would receive an incremental payment of €0.5 million. The EBITDA threshold was met for fiscal year 2014, and the Company recorded the contingent gain on sale of €0.5 million (approximately $0.6 million) related to this incremental payment for the year ended December 31, 2014. The payment was received during the first quarter of 2015 and is reflected within cash flows used in investing activities in the consolidated statement of cash flows for the year ended December 31, 2015.

Livorno Land Sale

In April 2014, the Company completed the sale of a portion of land at its manufacturing site in Livorno, Italy for a purchase price of €4.95 million (approximately $6.8 million). As a result, the Company recorded a gain on sale of $0.1 million within “Other expense, net” in the consolidated statements of operations for the year ended December 31, 2014.

NOTE 4—INVESTMENTS IN UNCONSOLIDATED AFFILIATES

The Company is supplemented by two strategic joint ventures, the results of which are included within the Basic Plastics & Feedstocks reporting segment: Americas Styrenics (a polystyrene joint venture with Chevron Phillips Chemical Company LP) and Sumika Styron Polycarbonate (a polycarbonate joint venture with Sumitomo Chemical Company Limited).

As of December 31, 2015 and 2014, respectively, the Company’s investment in Americas Styrenics was $143.9 million and $133.5 million, which was $91.9 million and $108.4 million less than the Company’s 50% share of Americas Styrenics’ underlying net assets. These amounts represent 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 4.8 years as of December 31, 2015. The Company received dividends from Americas Styrenics of $125.0 million, $35.0 million, and $22.5 million for the years ended December 31, 2015, 2014, and 2013, respectively.

As of December 31, 2015 and 2014, respectively, the Company’s investment in Sumika Styron Polycarbonate was $39.0 million and $34.1 million, which was $19.8 million and $21.3 million greater than the Company’s 50% share of Sumika Styron Polycarbonate’s underlying net assets. These amounts represent the fair value of certain identifiable assets which have not been recorded on the historical financial statements of Sumika Styron Polycarbonate. This difference is being amortized over the remaining useful life of the contributed assets of 9.8 years as of December 31,

During the year ended December 31, 2013, the Company determined that the long-lived assets at our polycarbonate manufacturing facility in Stade, Germany should be assessed for impairment driven primarily by continued losses experienced in the Company’s polycarbonate business. This assessment indicated that the carrying amount of the long-lived assets at this facility were not recoverable when compared to the expected undiscounted cash flows of the polycarbonate business. Based upon the assessment of fair value of this asset group, the Company concluded these assets were fully impaired as of December 31, 2013. The fair value of the asset group was determined under the income approach utilizing a discounted cash flow (“DCF”) model. The key assumptions used in the DCF model included growth rates and cash flow projections, discount rate, tax rate and an estimated terminal value.

As a result, the Company recorded an impairment loss on these assets of approximately $9.2 million for the year ended December 31, 2013. The amount was recorded within “Selling, general and administrative expenses” in the consolidated statements of operations and allocated entirely to the Basic Plastics & Feedstocks segment.

Goodwill impairment testing is performed annually as of October 1st. In 2015, the Company performed its annual impairment test for goodwill and determined that the estimated fair value of each reporting unit was substantially in excess of the carrying value indicating that none of the Company’s goodwill was impaired. The Company concluded there were no goodwill impairments or triggering events for the years ended December 31, 2015, 2014, and 2013.

As of December 31, 2015, the Company had $24.5 million capitalized as software in development, primarily related to our project to upgrade our legacy ERP environment to the latest version of SAP.  This project is expected to be completed and placed into service in 2016.

In March 2014, the Company entered into an agreement with material supplier JSR Corporation, Tokyo (“JSR”) to acquire its current production capacity rights at the Company’s rubber production facility in Schkopau, Germany for a purchase price of €19.0 million (approximately $26.1 million based upon the acquisition date foreign exchange rate). Prior to this agreement, JSR held 50% of the capacity rights of one of the Company’s three solution styrene-butadiene rubber (“SSBR”) production trains in Schkopau. As a result, effective March 31, 2014, the Company had full capacity rights to this production train. The €19.0 million purchase price was recorded in “Other intangible assets, net” in the consolidated balance sheets, and is being amortized over its estimated useful life of approximately 6.0 years. Further, the

Total accrued interest on outstanding debt as of December 31, 2015 and 2014 was $7.8 million and $43.5 million, respectively. Accrued interest is recorded in “Accrued expenses and other current liabilities” within the consolidated balance sheets.

2018 Senior Secured Credit Facility

In June 2010, the Company entered into a credit agreement, which was subsequently amended on February 2, 2011, July 28, 2011, February 13, 2012, August 9, 2012, January 19, 2013, and December 3, 2013 and was set to mature in January 2018 (“2018 Senior Secured Credit Facility”).  Under the 2018 Senior Secured Credit Facility, the Company had certain term loan borrowings outstanding through the end of 2012 (the “Term Loans”). 

F-20

In January 2013, the Company amended the 2018 Senior Secured Credit Facility (the “2013 Amendment”) to, among other things, repay its then outstanding Term Loans of $1,239.0 million using the proceeds from its sale of its 2019 Senior Notes (discussed below). As a result, the Company recognized a $20.7 million loss on extinguishment of debt during the year ended December 31, 2013, which consisted of the write-off of existing unamortized deferred financing fees and debt discount attributable to the Term Loans. Fees and expenses incurred in connection with the 2013 Amendment were $5.5 million, which were capitalized.

The 2018 Senior Secured Credit Facility also included a revolving credit facility (“2018 Revolving Facility”), which, as a result of the 2013 Amendment, included a borrowing capacity of $300.0 million, with an applicable margin rate of 3.00% as applied to base rate loans (which shall bear interest at a rate per annum equal to the base rate plus the applicable margin (as defined therein)), or 4.00% as applied to LIBO rate loans (which shall bear interest at a rate per annum equal to the LIBO rate plus the applicable margin and the mandatory cost (as defined therein), if applicable), and a maturity date of January 2018. As of December 31, 2014, there were no amounts outstanding under the 2018 Revolving Facility, while available borrowings under the facility were $293.3 million (net of $6.7 million outstanding letters of credit).

Capitalized fees and costs incurred in connection with the Company’s 2018 Revolving Facility were recorded in “Deferred charges and other assets” within the consolidated balance sheets and were amortized using a straight-line method over the term of the facility. Amortization of deferred financing fees are recorded in “Interest expense, net” in the consolidated statements of operations.  Unamortized deferred financing fees related to the 2018 Revolving Facility were $8.8 million as of December 31, 2014.

The Company recorded interest expense relating to the amortization of deferred financing fees and debt discounts related to the entire 2018 Senior Secured Credit Facility, respectively, of $1.0 million and zero for the year ended December 31, 2015; $2.9 million and zero for the year ended December 31, 2014; and $3.1 million and $0.1 million for the year ended December 31, 2013.

In May 2015, upon completion of the refinancing transactions discussed below, the Company terminated the 2018 Senior Secured Credit Facility.  Immediately prior to this termination, the Company had no outstanding borrowings under the 2018 Revolving Facility. As a result of this termination, the Company recognized a $0.7 million loss on extinguishment of long-term debt, comprised entirely of the write-off of a portion of the existing unamortized deferred financing fees related to the 2018 Revolving Facility.  The remaining unamortized deferred financing fees under the 2018 Revolving Facility totaled $7.2 million, which remained capitalized and are being amortized along with the new deferred financing fees over the life of the new revolving credit facility, discussed in further detail below.

Interest charges, excluding interest expense relating to the amortization of deferred financing fees and debt discounts, incurred on the Term Loans and 2018 Revolving Facility, respectively, were zero and $0.6 million for the year ended December 31, 2015, zero and $1.8 million for the year ended December 31, 2014, and $7.7 million and $2.8 million for the year ended December 31, 2013. Cash paid related to interest incurred on the Term Loans and 2018 Revolving Facility, respectively, was zero and $0.6 million for the year ended December 31, 2015, zero and $1.9 million for the year ended December 31, 2014, and $16.5 million and $2.8 million for the year ended December 31, 2013.

Senior Credit Facility

On May 5, 2015, Trinseo Materials Operating S.C.A. and Trinseo Materials Finance, Inc. (together, the “Issuers” or the “Borrowers”), both wholly-owned subsidiaries of the Company, entered into a senior secured credit agreement (the “Credit Agreement”), which provides senior secured financing of up to $825.0 million (the “Senior Credit Facility”).  The Senior Credit Facility provides for senior secured financing consisting of a (i) $325.0 revolving credit facility, with a $25.0 million swingline subfacility and a $35.0 million letter of credit subfacility (the “2020 Revolving Facility”) maturing in May 2020 and (ii) $500.0 million senior secured term loan B facility maturing in November 2021 (the “2021 Term Loan B”). Amounts under the 2020 Revolving Facility are available in U.S. dollars and euros.

The 2021 Term Loan B bears an interest rate of LIBOR plus 3.25%, subject to a 1.00% LIBOR floor, and was issued at a 0.25% original issue discount.  Further, the 2021 Term Loan B requires scheduled quarterly payments in amounts equal to 0.25% of the original principal amount of the 2021 Term Loan B, with the balance to be paid at maturity. During the year ended December 31, 2015, the Company made principal payments of $2.5 million related to the 2021 Term Loan B. As of December 31, 2015, $5.0 million of these scheduled future payments were classified as current debt on the Company’s consolidated balance sheets.

F-21

Loans under the 2020 Revolving Facility, at the Borrowers’ option, may be maintained as (a) LIBO rate loans, which bear interest at a rate per annum equal to the LIBO rate plus the applicable margin (as defined in the Credit Agreement), if applicable, or (b) base rate loans which shall bear interest at a rate per annum equal to the base rate plus the applicable margin (as defined in the Credit Agreement).  As of December 31, 2015, the Borrowers will be required to pay a quarterly commitment fee in respect of any unused commitments under the 2020 Revolving Facility equal to 0.375% per annum.

As of December 31, 2015, the Company had no outstanding borrowings, and had $311.5 million (net of $13.5 million outstanding letters of credit) of funds available for borrowing under the 2020 Revolving Facility.

The Senior Credit Facility is collateralized by a security interest in substantially all of the assets of Trinseo Materials Operating S.C.A., as lead borrower, Trinseo Materials Finance, Inc., as co-borrower, and the guarantors thereunder including Trinseo Materials S.à r.l., certain U.S. subsidiaries and certain foreign subsidiaries organized in Luxembourg, The Netherlands, Hong Kong, Singapore, Ireland, Germany and Switzerland.

The Senior Credit Facility requires the Borrowers and their restricted subsidiaries to comply with customary affirmative and negative covenants, including limitations on their abilities to incur liens; make certain loans and investments; incur additional debt; merge, consolidate liquidate or dissolve; transfer or sell assets; pay dividends and other distributions to shareholders or make certain other restricted payments; enter into transactions with affiliates; restrict any restricted subsidiary from paying dividends or making other distributions or agree to certain negative pledge clauses; materially alter the business they conduct; prepay certain other indebtedness; amend certain material documents; and change our fiscal year.

The 2020 Revolving Facility contains a financial covenant that requires compliance with a springing first lien net leverage ratio test. If the outstanding balance under the 2020 Revolving Facility exceeds 30% of the $325.0 million borrowing capacity (excluding undrawn letters of credit up to $10.0 million and cash collateralized letters of credit) at a quarter-end, then the Company’s first lien net leverage ratio may not exceed 2.00 to 1.00.  As of December 31, 2015, the Company was in compliance with all debt covenant requirements under the Senior Credit Facility.

Fees and expenses incurred in connection with the issuance of the 2021 Term Loan B and the 2020 Revolving Facility were $12.0 million and $0.3 million, respectively, which were capitalized and recorded in “Deferred charges and other assets” in the consolidated balance sheets.

For the 2021 Term Loan B, deferred financing fees and the 0.25% debt discount are being amortized over its 6.5 year term using the effective interest method.  For the 2020 Revolving Facility, deferred financing fees (along with an additional $7.2 million of unamortized deferred financing fees from the 2018 Revolving Facility) are being amortized over its 5.0 year term using the straight-line method.  Amortization of deferred financing fees and debt discounts are recorded in “Interest expense, net” in the consolidated statements of operations.

Unamortized deferred financing fees and debt discount related to the 2021 Term Loan B were $10.9 million and $1.1 million, respectively, as of December 31, 2015. Unamortized deferred financing fees related to the 2020 Revolving Facility were $6.5 million as of December 31, 2015. The Company recorded interest expense relating to the amortization of deferred financing fees and debt discounts related to the entire Senior Credit Facility, respectively, of $2.1 million and $0.1 million for the year ended December 31, 2015.

Interest charges, excluding interest expense relating to the amortization of deferred financing fees and debt discounts, incurred on the 2021 Term Loan B and 2020 Revolving Facility, respectively, were $14.2 million and $1.3 million for the year ended December 31, 2015. Cash paid related to interest incurred on the 2021 Term Loan B and 2020 Revolving Facility, respectively, was $14.2 million and $1.3 million during the year ended December 31, 2015.

2019 Senior Notes

In January 2013, the Company issued $1,325.0 million 8.750% senior notes due to mature on February 1, 2019 (the “2019 Senior Notes”). The proceeds from the issuance of the 2019 Senior Notes were used to repay all of the Company’s then outstanding Term Loans and related refinancing fees and expenses.

In July 2014, using proceeds from the Company’s IPO (see Note 12), the Company redeemed $132.5 million in aggregate principal amount of the 2019 Senior Notes, together with a 103% call premium totaling $4.0 million and accrued and unpaid interest thereon of $5.2 million.

December 31, 2014 the Company incurred a loss on the extinguishment of debt of approximately $7.4 million, which includes the above $4.0 million call premium and an approximately $3.4 million write-off of related unamortized deferred financing fees.

On May 13, 2015, using the net proceeds from the issuance of the 2021 Term Loan B, together with the net proceeds from the issuance of the 2022 Senior Notes (defined and discussed below) and available cash, the Company redeemed all outstanding borrowings under the 2019 Senior Notes, totaling $1,192.5 million in principal, together with a call premium of $68.6 million (with a redemption price of 103% on the first $132.5 million and 106.097% on the remaining balance) and accrued and unpaid interest thereon of $29.6 million.

For the year ended December 31, 2015, the Company recorded $2.1 million in amortization of deferred financing fees on the 2019 Senior Notes, noting no unamortized deferred financing fees remained on the consolidated balance sheet as of December 31, 2015 due to the redemption in May 2015. For the year ended December 31, 2014, the Company recorded $5.7 million in amortization of deferred financing fees, leaving $28.0 million of unamortized deferred financing fees related to the 2019 Senior Notes on the consolidated balance sheet as of December 31, 2014. For the year ended December 31, 2013, the Company recorded $4.9 million in amortization of deferred financing fees.

Cash paid for interest on the 2019 Senior Notes was $81.7 million, $115.4 million, and $58.6 million for the years ended December 31, 2015, 2014, and 2013, respectively.

2022 Senior Notes

On May 5, 2015, the Issuers executed an indenture (the “Indenture”) pursuant to which they issued $300.0 million aggregate principal amount of 6.750% senior notes due May 1, 2022 (the “USD Notes”) and €375.0 million aggregate principal amount of 6.375% senior notes due May 1, 2022 (the “Euro Notes”, and together with the USD Notes, the “2022 Senior Notes”).  Interest on the 2022 Senior Notes is payable semi-annually on May 1 and November 1 of each year, commencing on November 1, 2015.

At any time prior to May 1, 2018, the Issuers may redeem the Euro Notes and/or the USD Notes in whole or in part, at their option at a redemption price equal to 100% of the principal amount of such notes plus the relevant applicable premium as of, and accrued and unpaid interest to, but not including, the redemption date. At any time and from time to time after May 1, 2018, the Issuers may redeem the Euro Notes and/or the USD Notes, in whole or in part, at a redemption price equal to the percentage of principal amount set forth below plus accrued and unpaid interest, if any, on the notes redeemed to, but not including, the redemption date:

The 2022 Senior Notes are the Issuers’ senior unsecured obligations and rank equally in right of payment with all of the Issuers’ existing and future indebtedness that is not expressly subordinated in right of payment thereto. The 2022 Senior Notes will be senior in right of payment to any future indebtedness that is expressly subordinated in right of payment thereto and effectively junior to (a) the Issuers’ existing and future secured indebtedness, including the Company’s accounts receivable facility and the Issuers’ Senior Credit Facility (discussed above), to the extent of the value of the collateral securing such indebtedness and (b) all existing and future liabilities of the Issuers’ non-guarantor subsidiaries.

The Indenture contains customary covenants that, among other things, limit the Issuers’ and certain of their subsidiaries’ ability to incur additional indebtedness and guarantee indebtedness, pay dividends or make other distributions, make investments, or prepay certain indebtedness, each subject to a number of exceptions and qualifications. Certain of these covenants, will be suspended during any period of time that (1) the 2022 Notes have investment grade ratings (as defined in the Indenture) and (2) no default has occurred and is continuing under the Indenture. In the event that the 2022 Senior Notes are downgraded to below an investment grade rating, the Issuers and certain subsidiaries will again be subject to the suspended covenants with respect to future events. As of December 31, 2015, the Company was in compliance with all debt covenant requirements under the Indenture.

Fees and expenses incurred in connection with the issuance of the 2022 Senior Notes were $16.0 million, which were capitalized and recorded in “Deferred charges and other assets” in the consolidated balance sheets, and are being amortized into “Interest expense, net” in the consolidated statements of operations over their 7.0 year term using the effective interest method.

For the year ended December 31, 2015, the Company recorded $1.2 million in amortization of deferred financing fees, leaving $14.8 million of unamortized deferred financing fees on the consolidated balance sheet as of December 31, 2015.

Interest expense on the 2022 Senior Notes, excluding expense relating to the amortization of deferred financing fees, was $30.5 million for the year ended December 31, 2015. Cash paid for interest on the 2022 Senior Notes was $22.8 million for the year ended December 31, 2015.

Accounts Receivable Securitization Facility

In 2010, Styron Receivable Funding Ltd. (“SRF”), a VIE in which the Company is the primary beneficiary, executed an agreement for an accounts receivable securitization facility (“Accounts Receivable Securitization Facility”). As of December 31, 2015, the facility, as previously amended in May 2013, permitted borrowings by one of the Company’s subsidiaries, Trinseo Europe GmbH (“TE”), up to a total of $200.0 million and had a maturity date of May 2016.  In February 2016, the facility was again amended, extending the maturity date to May 2019.

Under the facility, TE sells its accounts receivable from time to time to SRF. In turn, SRF may sell undivided ownership interests in such receivables to commercial paper conduits in exchange for cash. The Company has agreed to continue servicing the receivables for SRF. Upon the sale of the interests in the accounts receivable by SRF, the conduits have a first priority perfected security interest in such receivables and, as a result, the receivables will not be available to the creditors of the Company or its other subsidiaries.

The Accounts Receivable Securitization Facility is subject to interest charges against the amount of outstanding borrowings as well as the amount of available, but undrawn commitments. In regards to outstanding borrowings, fixed interest charges are 2.6% plus variable commercial paper rates, while for available, but undrawn commitments, fixed interest charges are 1.40%.  

As of December 31, 2015 and 2014, there were no amounts outstanding under the Accounts Receivable Securitization Facility, with approximately $123.4 million and $136.1 million, respectively, of funds available for borrowing under this facility, based on the pool of eligible accounts receivable. Interest expense on the Accounts Receivable Securitization Facility, excluding interest expense relating to the amortization of deferred financing fees, for the years ended December 31, 2015, 2014 and 2013 was $2.8 million, $2.9 million and $4.2 million, respectively, and was recorded in “Interest expense, net” in the consolidated statements of operations.

Unamortized deferred financing fees related to the Accounts Receivable Securitization Facility were $0.5 million and $1.9 million as of December 31, 2015 and 2014, respectively, recorded in “Deferred charges and other assets” within

F-24

the consolidated balance sheets. These charges are being amortized on a straight-line basis over the term of the facility. The Company recorded $1.2 million, $1.4 million and $1.4 million in amortization of deferred financing fees related to the Accounts Receivable Securitization Facility in “Interest expense, net” within the consolidated statements of operations for the years ended December 31, 2015, 2014 and 2013, respectively.

Other Indebtedness

The Company has a short-term revolving facility through our subsidiary in China that provides uncommitted funds available for borrowing, subject to the availability of collateral. The facility is subject to annual renewal.

Outstanding borrowings under this revolving facility were zero and $7.6 million as of December 31, 2015 and 2014, respectively. The revolving facility is guaranteed by the Company’s holding company, Trinseo Materials Operating S.C.A. or secured by pledge of certain of the Company’s assets in China. As of December 31, 2015 and 2014, the weighted average interest rate of the facility was approximately zero and 0.1%, respectively.

NOTE 11—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 consolidated balance sheets at fair value. For fair value disclosures related to these instruments refer to Note 13.

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 December 31, 2015, the Company had open foreign exchange forward contracts with a net notional U.S. dollar equivalent absolute value of $371.8 million. The following table displays the notional amounts of the most significant net foreign exchange hedge positions outstanding as of December 31, 2015.

	December 31,

Chinese Yuan	$	(122,907)
Euro	$	109,049
Indonesian Rupiah	$	(58,212)
Swiss Franc	$	36,856
British Pound	$	(16,124)

Open foreign exchange forward contracts as of December 31, 2015 have maturities of less than three months.

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

F-25

income (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 December 31, 2015 have maturities occurring over a period of 12 months, and have a net notional U.S. dollar equivalent of $168.0 million.

Net Investment Hedge

The Company’s outstanding debt includes €375.0 million of Euro Notes (see Note 10 for details).  As of December 31, 2015, the Company has designated a portion (€150.0 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 gain of$0.4 million within accumulated other comprehensive loss as of December 31, 2015.

Summary of Derivative Instruments

The Company recorded losses of $16.5 million, $28.2 million and $0.6 million during the years ended December 31, 2015, 2014, and 2013, respectively, from settlements and changes in the fair value of outstanding forward contracts (not designated as hedges) which are recognized in “Other expense, net” in the consolidated statements of operations. The losses from these forward contracts offset net foreign exchange transaction gains of $6.1 million and $32.4 million during the years ended December 31, 2015 and 2014, respectively, and were incremental to net foreign exchange transaction losses of $18.3 million during the year ended December 31, 2013, 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 consolidated statements of cash flows.

As of December 31, 2015, the Company has no ineffectiveness related to its foreign exchange cash flow hedges. In the next twelve months, the Company expects to reclassify an approximate $5.0 million net gain from other comprehensive income (loss) into earnings related to the Company’s outstanding cash flow hedges as of December 31, 2015, based on current foreign exchange rates.

NOTE 12—SHAREHOLDERS’ EQUITY

Ordinary Shares

On May 30, 2014, the Company amended its Articles of Association to effect a 1-for-436.69219 reverse split of its issued and outstanding ordinary shares and to increase its authorized ordinary shares to 50.0 billion. Pursuant to the reverse split, every 436.69219 shares of the Company’s then issued and outstanding ordinary shares was converted into one ordinary share. The reverse split did not change the par value of the Company’s ordinary shares. These consolidated financial statements and accompanying footnotes have been retroactively adjusted to give effect to the reverse split.

On June 17, 2014, the Company completed the IPO of 11,500,000 ordinary shares at a price of $19.00 per share. The number of ordinary shares at closing included 1,500,000 of shares sold pursuant to the underwriters’ over-allotment option. The Company received cash proceeds of $203.2 million from this transaction, net of underwriting discounts. These net proceeds were used by the Company for: i) the July 2014 repayment of $132.5 million in aggregate principal amount of the 8.750% Senior Notes due 2019, together with accrued and unpaid interest thereon of $5.2 million and a call premium of $4.0 million (see Note 10); ii) the payment of approximately $23.3 million in connection with the termination of the Advisory Agreement with Bain Capital (see Note 18); iii) the payment of approximately $5.1 million

F-27

of advisory, accounting, legal and printing expenses directly related to the offering which were recorded as a reduction to additional paid-in capital in the consolidated balance sheets; and iv) general corporate purposes.

NOTE 13—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 consolidated balance sheets at December 31, 2015 and 2014.

The Company uses an income approach to value its foreign exchange forward contracts and foreign exchange cash flow hedges, 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

F-28

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 within the fair value hierarchy.

Fair Value of Debt Instruments

The Company had valuation allowances which were related to the realization of recorded tax benefits on tax loss carryforwards, as well as other net deferred tax assets, primarily from subsidiaries in Luxembourg and Australia, of $85.1 million as of December 31, 2015 and $66.9 million as of December 31, 2014.  In addition, the Company recorded a valuation allowance of $7.3 million on the net deferred tax asset of one of its China subsidiaries during the fourth quarter of 2015, as this entity was in a three year cumulative loss position as of December 31, 2015 and the Company could no longer assert it would more likely than not be able to realize its deferred tax asset.  If in the future, this subsidiary generates sufficient profitability such that the evaluation of recoverability of the deferred tax asset changes, the valuation allowance could be reversed.  

For the years presented, a reconciliation of the beginning and ending amount of the unrecognized tax benefits is as follows:

Balance as of December 31, 2012	$	30,079
Increases related to current year tax positions		1,225
Decreases related to prior year tax positions		(4,405)
Balance as of December 31, 2013	$	26,899
Increases related to current year tax positions		187
Decreases related to prior year tax positions		(6,701)
Balance as of December 31, 2014	$	20,385
Increases related to current year tax positions		1,304
Decreases related to prior year tax positions		(1,647)
Balance as of December 31, 2015	$	20,042

The Company recognized interest and penalties of $0.7 million, less than $0.1 million, and $0.7 million for the years ended December 31, 2015, 2014, and 2013, respectively, which was included as a component of income tax expense in the consolidated statements of operations. As of December 31, 2015 and 2014, the Company had $2.3 million and $1.8 million, respectively, accrued for interest and penalties. To the extent that the unrecognized tax benefits are recognized in the future, $16.7 million will impact the Company’s effective tax rate. In addition, the Company estimates that approximately $1.0 million of current unrecognized tax benefits may be realized within the next twelve months as the result of a lapse of statute limitations.

As a majority of the Company’s legal entities had no significant activity prior to or were formed in 2010, only the 2010 tax year and forward is subject to examination in the majority of jurisdictions, except for China, Hong Kong, and Indonesia where tax years between 2007 and 2009 remain subject to examination. Pursuant to the terms of the Purchase Agreement, the Company has been indemnified from and against any taxes for or with respect to any periods prior to the Acquisition.

NOTE 15—COMMITMENTS AND CONTINGENCIES

Leased Property

The Company routinely leases premises for use as sales and administrative offices, warehouses and tanks for product storage, motor vehicles, railcars, computers, office machines, and equipment under operating leases. Rental expense for these leases was $18.4 million, $15.9 million and $16.2 million during the years ended December 31, 2015, 2014, and 2013, respectively.

Future minimum rental payments under operating leases with remaining non-cancelable terms in excess of one year are as follows:

	Annual
Year	Commitment
2016	$	8,959
2017		6,660
2018		6,207
2019		5,835
2020		4,273
Thereafter		7,637
Total	$	39,571

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. As of December 31, 2015 and 2014, the Company had no accrued obligations for environmental remediation and restoration costs. Pursuant to the terms of the Acquisition, the pre-closing environmental conditions were retained by Dow and the Company has been indemnified by Dow from and against all environmental liabilities incurred or relating to the predecessor periods. There are several properties which the Company now owns on which Dow has been conducting investigation, monitoring, or remediation to address historical contamination. Those properties include Allyn’s Point, Connecticut, Dalton, Georgia, and Livorno, Italy. There are other properties with historical contamination that are owned by Dow that the Company leases for its operations, including its facilities in Midland, Michigan, Schkopau, Germany, Terneuzen, The Netherlands, and Guaruja, Brazil. No environmental claims have been asserted or threatened against the Company, and the Company is not a potentially responsible party at any Superfund Sites.

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 consolidated financial statements.

There were no amounts recorded in the consolidated statement of operations relating to environmental remediation for the years ended December 31, 2015, 2014, and 2013.

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. The following table presents the fixed and determinable portion of the obligation under the Company’s purchase commitments as of December 31, 2015 (in millions):

	Annual
Year	Commitment
2016	$	1,312
2017		1,035
2018		1,175
2019		922
2020		1,026
Thereafter		—
Total	$	5,470

F-32

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 obligations shown in the table above.

The Company has service agreements with Dow and Bain Capital, some of which contain fixed annual fees. See Note 18 for further discussion.

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 16—PENSION PLANS AND OTHER POSTRETIREMENT BENEFITS

Defined Benefit Pension Plans

Many of the Company’s employees are participants in various defined benefit pension plans which are administered and sponsored by the Company and are primarily in Germany, Switzerland, The Netherlands, Belgium and Japan.

In connection with the Acquisition, the Company and Dow entered into affiliation agreements in certain jurisdictions (the “Affiliation Agreements”) allowing employees who transferred from Dow to the Company as of June 17, 2010 to remain in the Dow operated pension plans (“Dow Plans”) until the Company established its own pension plan. The Company then made the required employer contribution amounts to the Dow Plans for the Company’s employees and the related pension benefit obligations for the Company’s employees have been accumulating in the Dow Plans since the Acquisition Date. Since June 2010, the Dow Plans originally established in those jurisdictions, were gradually legally separated into the Company’s self administered and sponsored plans until the Affiliation Agreements ended on December 31, 2012.

In Switzerland and The Netherlands, all remaining employees of the Company who were previously participants of the Dow Plans transferred to separately administered and sponsored pension plans of the Company effective January 1, 2013 (the “Successor Plans”). The benefit obligation and related plan assets in the Dow Plans belonging to the Company’s employees were transferred to the Successor Plans. As a result of the transfer, the Company recognized prior service credits and net losses of approximately $13.0 million and $1.4 million, respectively in other comprehensive income during the year ended December 31, 2013.

Company employees who were not previously associated with the acquired pension and postretirement plans are generally not eligible for enrollment in these plans. Pension benefits are typically based on length of service and the employee’s final average compensation.

Other Postretirement Benefits

The Company, either through a Company benefit plan or government-mandated benefits, provides certain health care and life insurance benefits applicable primarily to Dow-heritage retired employees, primarily in the U.S., as well as in Brazil.

In the U.S., the plan provides for health care benefits, including hospital, physicians’ services, drug and major medical expense coverage. In general, the plan applies to employees hired by Dow before January 1, 2008 and transferred to the Company in connection with the Acquisition, and who are at least 50 years old with 10 years of service. The plan allows for spouse coverage as well. If an employee was hired on or before January 1, 1993, the coverage extends past age 65. For employees hired after January 1, 1993 but before January 1, 2008, coverage ends at

F-33

age 65. The Company reserves the right to modify the provisions of the plan at any time, including the right to terminate, and does not guarantee the continuation of the plan or its provisions.

In Brazil, the Company provides an insured medical benefit to all employees and eligible dependents under Brazil’s healthcare legislation, which grants the right to employees (and their beneficiaries) who have contributed towards the medical plan to extend medical coverage upon retirement or in case of involuntary dismissal. The extended medical plan must include the same level of coverage and other conditions offered to active employees, whereas former employees must assume 100% of the premium cost. Prior to 2014, the Company had not accrued for the postretirement benefits owed under this plan. As a result, for the year ended December 31, 2014, a $2.7 million liability was recorded, which includes an adjustment related to the original purchase price allocation from the Acquisition as a portion of this obligation was assumed from Dow. The impact of this adjustment was a $1.7 million increase to goodwill and $1.0 million of net periodic benefit costs, net of currency remeasurement gains, incurred from the date of the Acquisition through December 31, 2013. The Company does not believe these adjustments were material to any prior period financial statements.

In The Netherlands, the Company previously provided postretirement medical benefits to Dow-heritage employees who transferred to the Company in connection with the Acquisition. The Company ceased providing these benefits effective January 1, 2015. As a result, the Company recognized approximately $1.5 million of curtailment gain for the year ended December 31, 2014.

Assumptions

The weighted-average assumptions used to determine pension plan obligations and net periodic benefit costs are provided below:

	Pension Plan Obligations						Net Periodic Benefit Costs
	December 31,						December 31,
	2015		2014		2013		2015		2014		2013
Discount rate	2.06	%	2.01	%	3.30	%	2.01	%	3.30	%	3.05	%
Rate of increase in future compensation levels	2.68	%	2.71	%	2.86	%	2.71	%	2.86	%	2.69	%
Expected long-term rate of return on plan assets	N/A		N/A		N/A		1.73	%	2.83	%	2.44	%

The weighted-average assumptions used to determine other postretirement benefit (“OPEB”) obligations and net periodic benefit costs are provided below:

	OPEB Obligations						Net Periodic Benefit Costs
	December 31,						December 31,
	2015		2014		2013		2015		2014		2013
Discount rate	6.51	%	6.40	%	4.72	%	6.40	%	6.69	%	3.93	%
Initial health care cost trend rate	8.19	%	8.05	%	6.67	%	8.05	%	6.67	%	7.00	%
Ultimate health care cost trend rate	5.26	%	5.43	%	5.00	%	5.43	%	5.00	%	5.00	%
Year ultimate trend rate to be reached	2023		2021		2019		2021		2019		2019

The discount rate utilized to measure the pension and other postretirement benefit plans is based on the yield of high-quality fixed income debt instruments at the measurement date. Future expected, actuarially determined cash flows of the plans are matched against a yield curve to arrive at a single discount rate for each plan.

The expected long-term rate of return on plan assets is determined by performing a detailed analysis of key economic and market factors driving historical returns for each asset class and formulating a projected return based on factors in the current environment. Factors considered include, but are not limited to, inflation, real economic growth, interest rate yield, interest rate spreads, and other valuation measures and market metrics. The expected long-term rate of return for each asset class is then weighted based on the strategic asset allocation approved by the governing body for each plan. The historical experience with the pension fund asset performance is also considered.

F-34

A one-percentage point change in the assumed health care cost trend rate would have had a nominal effect on both service and interest costs, but would result in an approximate $0.7 million impact to the projected benefit obligation.

The net periodic benefit costs for the pension and other postretirement benefit plans for the years ended December 31, 2015, 2014, and 2013 were as follows:

	Defined Benefit Pension Plans									Other Postretirement Benefit Plans

(1) This amount represents settlement losses from one of the Company’s defined benefit plans in Switzerland due to the termination of certain employees during the year, which resulted in a loss recognized in the year ended December 31, 2014 due to a charge against the unamortized net loss recorded in other comprehensive income.

(2) This amount represents a curtailment loss from one of the Company’s defined benefit plans in Germany due to the reduction or cessation of benefit accruals for certain employees’ future services. The adjustment in the benefit obligation from the curtailment resulted in a loss recognized during the year ended December 31, 2013 due to a charge against the unamortized net loss recorded in other comprehensive income.

(3) This amount represents a curtailment gain from the Company’s other postretirement benefit plan in The Netherlands, due to the cessation of retiree medical benefit accruals effective January 1, 2015.

(4) This adjustment was made to the Company’s pension plan in The Netherlands to reflect the introduction of a salary cap and lower accrual rate on pension benefits as a result of tax law changes effective January 1, 2015. The impact of the change resulted in an adjustment to prior service credit in other comprehensive income as of December 31, 2014, which will be amortized to net periodic benefit cost over the estimated remaining service period of the employees.

(5) This is primarily related to the transfer of all remaining employees who were previously participants in the Dow Plans in Switzerland and The Netherlands to Company Successor Plans effective January 1, 2013, as discussed above.

(6) These amounts include the prior period net periodic cost and other comprehensive income components of the postretirement benefits in Brazil recognized during 2014, as discussed above.

F-35

(7) This amount is primarily related to a reduction in annuity conversion rates announced by the insurance provider for the pension plans in Switzerland. The impact of the change resulted in an adjustment to prior service credit in other comprehensive income as of December 31, 2015, which will be amortized to net periodic benefit cost over the estimated remaining service period of the employees.

The changes in the pension benefit obligations and the fair value of plan assets and the funded status of all significant plans for the year ended December 31, 2015 and 2014 were as follows:

(8) The amount represents an adjustment to the original purchase price allocation from the Acquisition as a portion of the postretirement benefits obligation recorded in Brazil was assumed from Dow.

(9) The fair values of certain plan assets as of December 31, 2015 and 2014 were determined using cash surrender values provided under the insurance contracts which took effect on January 1, 2013. The resulting change in the fair value of plan assets due to the use of cash surrender values was included as “return on plan assets”.

Total at end of period	$	62,170	$	75,741	$	(1,238)	$	362

Approximately $4.2 million and $1.9 million of net loss and net prior service credit, respectively, for the defined benefit pension plans and $0.2 million and $0.1 million of net gain and net prior service cost, respectively, for other postretirement benefit plans will be amortized from accumulated other comprehensive income (“AOCI”) to net periodic benefit cost in 2016.

The estimated future benefit payments, reflecting expected future service, as appropriate, are presented in the following table:

Estimated contributions to the defined benefit pension plans in 2016 are $14.4 million.

The following information relates to pension plans with projected and accumulated benefit obligations in excess of the fair value of plan assets as of December 31, 2015 and 2014:

Projected Benefit Obligation	December 31,

Plan Assets

As of December 31, 2015 and 2014, respectively, plan assets totaled $100.5 million and $92.6 million, consisting of investments in insurance contracts. Investments in the pension plan insurance were valued utilizing unobservable

F-37

inputs, which are contractually determined based on cash surrender values, returns, fees, and the present value of the future cash flows of the contracts.

Insurance contracts are classified as Level 3 investments. Changes in the fair value of these level 3 investments during the years ended December 31, 2015 and 2014 are included in the “Change in plan assets” table above.

Concentration of Risk

The Company mitigates the credit risk of investments by establishing guidelines with investment managers that limit investment in any single issue or issuer to an amount that is not material to the portfolio being managed. These guidelines are monitored for compliance both by the Company and external managers. Credit risk related to derivative activity is mitigated by utilizing multiple counterparties and through collateral support agreements.

Supplemental Employee Retirement Plan

The Company established a non-qualified supplemental employee retirement plan in 2010. The net benefit costs recognized for the years ended December 31, 2015, 2014, and 2013 were $1.0 million, $1.3 million, and $2.3 million, respectively. Benefit obligations under this plan were $13.7 million and $13.2 million as of December 31, 2015 and 2014, respectively. As of December 31, 2015 and 2014, the amounts of net loss included in AOCI were $1.6 million and $2.0 million, respectively, with $0.8 million amortized from AOCI into net periodic benefit costs during each of the years ended December 31, 2015 and 2014, respectively. Approximately $1.0 million is expected to be amortized from AOCI into net periodic benefit cost in 2016.

Based on the Company’s current estimates, the estimated future benefit payments under this plan, reflecting expected future service, as appropriate, are presented in the following table:

	2016		2017		2018		2019		2020		Thereafter		Total
Supplemental employee retirement plan	$	—	$	13,855	$	—	$	—	$	—	$	—	$	13,855

Defined Contribution Plans

The Company also offers defined contribution plans to eligible employees in the U.S. and in other countries, including China, Brazil, Hong Kong, Korea, The Netherlands, Taiwan and the United Kingdom. The defined contribution plans are comprised of a non-discretionary elective matching contribution component as well as a discretionary non-elective contribution component. Employees participate in the non-discretionary component by contributing a portion of their eligible compensation to the plan, which is partially matched by the Company. Non-elective contributions are made at the discretion of the Company and are based on a combination of eligible employee compensation and performance award targets. For the years ended December 31, 2015, 2014, and 2013, respectively, the Company contributed $7.8 million, $6.8 million, and $6.3 million to the defined contribution plans.

NOTE 17—STOCK-BASED COMPENSATION

Restricted Stock Awards issued by the Parent

On June 17, 2010, the Parent authorized the issuance of up to 750,000 shares in time-based and performance-based restricted stock to certain key members of management. Any related compensation associated with these awards is allocated to the Company from the Parent. With the adoption of the Trinseo S.A. 2014 Omnibus Incentive Plan (“2014 Omnibus Plan”) during 2014, discussed further below, restricted stock awards will no longer be issued by the Parent on behalf of the Company.

Time-based Restricted Stock Awards

The time-based restricted stock awards issued by the Parent contain a service-based condition that requires continued employment with the Company. Generally, these awards vest over three to five years of service, with a portion

F-38

(20% to 40%) cliff vesting after the first one or two years. The remaining portion of the awards vest ratably over the subsequent service period, subject to the participant’s continued employment with the Company, and vest automatically upon a change in control of the Company, excluding a change in control related to an IPO. Should a participant’s termination occur within a defined timeframe due to death or permanent disability, a termination of the participant by the Company or one of its subsidiaries without cause, or the participant’s voluntary resignation for good reason, the portion of awards that are subject to time-based vesting that would have vested on the next regular vesting date will accelerate and vest on a pro rata basis, based on the number of full months between the last regular vesting date and the termination date.

The Parent has a call right that gives it the option, but not the obligation, to repurchase vested stock at the then current fair value upon an employee’s termination, or at cost in certain circumstances. During the year ended December 31, 2013, as the result of certain employee terminations, the Parent repurchased a total of 3,372 previously vested time-based restricted stock awards at cost, resulting in a $0.9 million favorable adjustment to stock-based compensation expense. No such events occurred in 2015 or 2014.

Compensation cost for the time-based restricted stock awards is measured at the grant date based on the fair value of the award (discussed below) and is recognized as expense over the appropriate service period utilizing graded vesting.

Total compensation expense for time-based restricted stock awards was $2.5 million, $7.0 million, and $8.3 million for the years ended December 31, 2015, 2014, and 2013, respectively. As of December 31, 2015, there was $1.6 million of total unrecognized compensation cost related to time-based restricted stock awards, which is expected to be recognized over a weighted-average period of 1.7 years.

The following table summarizes the activity in the Parent’s time-based restricted stock awards during the year ended December 31, 2015:

(1) There were no grants of time-based restricted stock awards by the Parent during the years ended December 31, 2015 and 2014 as a result of the adoption of the 2014 Omnibus Plan, as discussed below.

Modified Time-based Restricted Stock Awards

In periods prior to June 2014, the performance-based restricted stock awards issued by the Parent contained provisions wherein vesting was subject to the full satisfaction of both time and performance vesting criterion. The performance component of the awards could only be satisfied if certain targets were achieved based on various returns realized by the Company’s shareholders on a change in control or an IPO. The time vesting requirements for the performance-based restricted stock awards generally vested in the same manner as the related time-based award. Prior to

F-39

the Company’s IPO in June 2014, the Company had not recorded any compensation expense related to these awards as the likelihood of achieving the existing performance condition of a change in control or IPO was not deemed to be probable.

On June 10, 2014, prior to the completion of the Company’s IPO, the Parent entered into agreements to modify the outstanding performance-based restricted stock awards held by the Company’s employees to remove the performance-based vesting condition associated with such awards related to the achievement of certain investment returns (while maintaining the requirement for a change in control or IPO). This modification also changed the time-based vesting requirement associated with such shares to provide that any shares which would have satisfied the time-based vesting condition previously applicable to such shares on or prior to June 30, 2017 will instead vest on June 30, 2017, subject to the holder remaining continuously employed by the Company through such date. Any such shares that are subject to a time-based vesting condition beyond June 30, 2017 will remain subject to the time-based vesting condition previously applicable to such awards. Henceforth, these awards have been described as the Company’s modified time-based restricted stock awards.

On June 17, 2014, with the completion of the Company’s IPO, the remaining performance condition associated with these modified time-based restricted stock awards was achieved. As a result, the Company began recognizing compensation expense on these awards, which was measured at the modification date based on the fair value of the awards and is being recognized as expense over the appropriate service period utilizing graded vesting.

Total compensation expense recognized for modified time-based restricted stock awards was $2.4 million and $2.5 million for the years ended December 31, 2015 and 2014, respectively.As of December 31, 2015, there was $4.5 million of total unrecognized compensation cost related to modified time-based restricted stock awards, which is expected to be recognized over a weighted-average period of 1.6 years.

The following table summarizes the activity in the Parent’s modified time-based restricted stock awards during the year ended December 31, 2015:

Fair Value Assumptions for Restricted Stock Award Grants

There were no grants by the Parent of time-based, performance-based, or modified time-based restricted stock awards during the years ended December 31, 2015 and 2014. However, as a result of the above-described June 2014 modification, the fair value of all modified time-based restricted stock awards was calculated as of the modification date. The fair values of time-based, modified time-based, and performance-based restricted stock awards (in prior years) were estimated on the date of grant using a combination of a call option and digital option model that uses assumptions about expected volatility, risk-free interest rates, the expected term, and dividend yield. In valuations performed prior to the IPO the expected term for performance-based awards considered management’s probability-weighted estimate of the expected time until a change in control or IPO as well as the time until a performance condition would be met. The expected term for time-based and modified time-based awards considered both the service conditions of vesting of the awards, as well as management’s probability-weighted estimate of the expected liquidity horizon. The expected volatilities were based on a combination of implied and historical volatilities of a peer group of companies, as the Company was a non-publicly traded company prior to the IPO. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with the expected life of the awards. The expected dividend yield was based on an assumption that no dividends were expected to be declared in the near future.

The following are the weighted average assumptions used for grants during the year ended December 31, 2013 and for valuation of the modified time-based awards in June 2014 (noting no grants or modifications during the year ended December 31, 2015):

	Year Ended December 31,
	2014		2013
Dividend yield	—	%	—	%
Expected volatility	65.00	%	73.25	%
Risk-free interest rate	1.54	%	0.52	%
Expected term (in years) for performance-based shares	N/A		3.85
Expected term (in years) for time-based and modified time-based shares	4.50		9.21

2014 Omnibus Plan

In connection with the IPO, the Company’s board of directors approved the 2014 Omnibus Plan, adopted on May 28, 2014, under which the maximum number of ordinary shares that may be delivered upon satisfaction of awards granted under such plan is 4.5 million shares. Following the IPO, all equity-based awards granted by the Company will be granted under the 2014 Omnibus Plan, which provides for awards of stock options, share appreciation rights, restricted stock, unrestricted stock, stock units, performance awards, cash awards and other awards convertible into or otherwise based on ordinary shares of the Company.  

During 2014, a limited number of awards were granted under the 2014 Omnibus Plan, noting grants of restricted share units (“RSUs”) to two of the Company’s directors.  During 2015, the board of directors of the Company approved a more broad-based equity award grant for directors and certain executives and employees, comprised of RSUs and options to purchase shares (“option awards”).

Restricted Share Units (RSUs)

The RSUs granted to executives and employees vest in full on the third anniversary of the date of grant, generally subject to the employee remaining continuously employed by the Company on the vesting date. RSUs granted to directors of the Company vest in full on the first anniversary of the date of grant.  Upon a termination of employment due to the employee’s death or retirement or a termination of employment by the Company without cause in connection with a restructuring or redundancy or due to the employee’s disability prior to the vesting date, the RSUs will vest in full or in part, depending on the type of termination. In the event employment is terminated for cause, all unvested RSUs will be forfeited. Dividends and dividend equivalents will not accumulate on unvested RSUs. Compensation costs for the RSUs are measured at the grant date based on the fair value of the award and are recognized ratably as expense over the applicable vesting term.

F-41

The fair value of RSUs is equal to the fair market value of the Company’s ordinary shares based on the closing price on the date of grant.

Total compensation expense for the RSUs was $2.1 million and $0.1 million for the years ended December 31, 2015 and 2014, respectively. As of December 31, 2015, there was $5.7 million of total unrecognized compensation cost related to the RSUs, which is expected to be recognized over a weighted-average period of 2.1 years. The following table summarizes the award activity for RSUs during the year ended December 31, 2015:

		Weighted-Average
		Grant Date
Restricted Share Units	Shares	Fair Value per Share
Unvested, December 31, 2014	9,472	$	19.00

(1) No RSUs vested during the year ended December 31, 2014.

Option Awards

The option awards, which contain an exercise term of nine years from the date of grant, vest in three equal annual installments beginning on the first anniversary of the date of grant, generally subject to the employee remaining continuously employed on the applicable vesting date. Upon a termination of employment due to the employee’s death or retirement or a termination of employment by the Company without cause in connection with a restructuring or redundancy or due to the employee’s disability prior to a vesting date, the options will vest in full or will continue to vest on the original vesting schedule, depending on the type of termination. In the event employment is terminated for cause, all vested and unvested options will be forfeited. Compensation cost for the option awards is measured at the grant date based on the fair value of the award and is recognized as expense over the appropriate service period utilizing graded vesting.

The fair value for option awards is computed using the Black-Scholes pricing model, whose inputs and assumptions are determined as of the date of grant. Determining the fair value of the option awards requires considerable judgment, including estimating the expected term of stock options and the expected volatility of the price of the Company’s ordinary shares.

Since the Company’s equity interests were privately held prior to the IPO in June 2014, there is limited publicly traded history of the Company’s ordinary shares, and as a result the expected volatility used in the Black-Scholes pricing model is based on the historical volatility of similar companies’ stock that are publicly traded as well as the Company’s debt-to-equity ratio. Until such time that the Company has enough publicly traded history of its ordinary shares to determine expected volatility based solely on its ordinary shares, estimated volatility of options granted will be based on a combination of our historical volatility and similar companies’ stock that are publicly traded. The expected term of options represents the period of time that options granted are expected to be outstanding. For the grants presented herein, the simplified method was used to calculate the expected term of options, given the Company’s limited historical exercise data. The risk-free interest rate for the periods within the expected term of the option is based on the U.S.

F-42

Treasury yield curve in effect at the time of grant. The dividend yield is assumed to be zero based on historical and expected dividend activity.

The following are the weighted-average assumptions used within the Black-Scholes pricing model for grants during the year ended December 31, 2015:

	Year Ended December 31,
	2015
Dividend yield	—	%
Expected volatility	45.00	%
Risk-free interest rate	1.65	%
Expected term (in years)	5.50

Total compensation expense for the option awards was $3.0 million for the year ended December 31, 2015. As of December 31, 2015, there was $1.3 million of total unrecognized compensation cost related to the option awards, which is expected to be recognized over a weighted-average period of 1.0 years. The following table summarizes the award activity for option awards during the year ended December 31, 2015:

Management Retention Awards

During the year ended December 31, 2012, the Parent agreed to retention awards with certain officers. These awards generally vest over one to four years, and are payable upon vesting subject to the participant’s continued employment with the Company on the vesting date. Compensation expense related to these retention awards is equivalent to the value of the award, and is recognized ratably over the applicable service period. Total compensation expense for these retention awards was $0.9 million and $1.4 million for the years ended December 31, 2014 and 2013, respectively, while for the year ended December 31, 2015 a net benefit of $1.1 million was recorded due to certain employment terminations, resulting in forfeited retention awards. As of December 31, 2015, there was no unrecognized compensation cost related to these retention awards.

Parent Company Restricted Stock Sales

During the year ended December 31, 2013, the Parent sold 779 shares of non-transferable restricted stock to certain employees, all of which were sold at a purchase price less than the fair value of the Parent’s common stock. As a result, during the year ended December 31, 2013, the Company recorded compensation expense of approximately

F-43

$0.2 million related to these restricted stock sales. There were no restricted stock sales during the years ended December 31, 2015 and 2014. The restricted stock may not be transferred without the Parent’s consent, except for a sale to the Parent or its investors in connection with a termination or on an IPO or other liquidation event.

Summary of Stock-based Compensation Expense

The amount of stock-based compensation expense recorded within “Selling, general and administrative expenses” in the consolidated statements of operations for the years ended December 31, 2015, 2014, and 2013, respectively, was as follows:

NOTE 18—RELATED PARTY AND DOW TRANSACTIONS

In conjunction with the Acquisition, the Company entered into certain agreements with Dow, including a five-year Master Outsourcing Services Agreement (“MOSA”) and certain Site and Operating Service Agreements. The MOSA provides for ongoing services from Dow in areas such as information technology, human resources, finance, environmental health and safety, training, supply chain and purchasing. Effective June 1, 2013, the Company entered into a Second Amended and Restated Master Outsourcing Services Agreement (“SAR MOSA”). The SAR MOSA replaces, modifies and extends the earlier MOSA, extending the term through December 31, 2020 and which automatically renews for two year periods unless either party provides six months’ notice of non-renewal to the other party. The services provided pursuant to the SAR MOSA generally are priced per function, and the Company has the ability to terminate the services or any portion thereof, for convenience any time after June 1, 2015, subject to payment of termination charges. Services which are “highly integrated” follow a different process for evaluation and termination. In addition, either party may terminate for cause, which includes a bankruptcy, liquidation or similar proceeding by the other party, for material breach which is not cured, or by Dow in the event of our failure to pay for the services thereunder. In the event of a change of control, as defined in the agreement, Dow has the right to terminate the SAR MOSA. As of December 31, 2015, the estimated minimum contractual obligations under the SAR MOSA are approximately$28.2 million.

In addition, the Company entered into certain Site and Operating Service Agreements. Under the Site Services Agreements (“SSAs”), Dow provides the Company utilities and other site services for Company-owned plants. Under the Operating Services agreements the Company provides services to Dow and receives payments for the operation of a Dow-owned plant. Similar to the above SAR MOSA, effective June 1, 2013, the Company entered into Second Amended and Restated Site Services Agreements (“SAR SSAs”). The SAR SSAs replace, modify and extend the original SSAs. These agreements generally have 25-year terms, with options to renew. These agreements may be terminated at any time by agreement of the parties, or, by either party, for cause, including a bankruptcy, liquidation or similar proceeding by the other party, or under certain circumstances for a material breach which is not cured. In

F-44

addition, the Company may terminate for convenience any services that Dow has agreed to provide that are identified in any site services agreement as “terminable” with 12 months prior notice to Dow, dependent upon whether the service is highly integrated into Dow operations. Highly integrated services are agreed to be nonterminable. With respect to “nonterminable” services that Dow has agreed to provide to the Company, such as electricity and steam, the Company generally cannot terminate such services prior to the termination date unless the Company experiences a production unit shut down for which Dow is provided with 15-months prior notice, or upon payment of a shutdown fee. Upon expiration or termination, the Company would be obligated to pay a monthly fee to Dow, which obligation extends for a period of 45 (in the case of expiration) to 60 months (in the case of termination) following the respective event of each site services agreement. The agreements under which Dow receives services from the Company may be terminated under the same circumstances and conditions.

For the years ended December 31, 2015, 2014, and 2013, the Company incurred a total of $242.1 million, $282.5 million, and $303.2 million in expenses under these agreements, respectively, including $194.1 million, $233.7 million, and $235.1million, for both the variable and fixed cost components of the Site Service Agreements, respectively, and $48.0 million, $48.8 million, and $68.1 million covering all other agreements, respectively. The following tables detail these expenses by financial statement line item:

In connection with the Acquisition, certain of the Company’s affiliates entered into a latex joint venture option agreement (the “Latex JV Option Agreement”) with Dow, pursuant to which Dow was granted an irrevocable option to purchase 50% of the issued and outstanding interests in a joint venture to be formed by Dow and the Company’s affiliates with respect to the SB Latex business in Asia, Latin America, the Middle East, Africa, Eastern Europe, Russia and India. On May 30, 2014, the Company’s affiliates entered into an agreement with Dow to terminate the Latex JV Option Agreement, Dow’s rights to the option, and all other obligations thereunder, in exchange for a termination payment of $32.5 million. This termination payment was made on May 30, 2014, and the termination of the Latex JV Option Agreement became effective as of such date. This termination payment was recorded as an expense within “Other expense, net” in the consolidated statements of operations for the year ended December 31, 2014.

In addition, the Company has transactions in the normal course of business with Dow and its affiliates. For the years ended December 31, 2015, 2014, and 2013, sales to Dow and its affiliated companies were approximately $227.0 million, $343.8 million, and $294.7 million, respectively. For the years ended December 31, 2015, 2014, and 2013, purchases (including MOSA and SSA services) from Dow and its affiliated companies were approximately $1,244.2 million, $2,196.0 million, and $2,336.5 million, respectively.

As of December 31, 2015 and 2014, receivables from Dow and its affiliated companies were approximately $21.5 million and $18.7 million, respectively, and are included in “Accounts receivable, net of allowance” in the consolidated balance sheets. As of December 31, 2015 and 2014, payables to Dow and its affiliated companies were

F-45

approximately $96.7 million and $156.9 million, respectively, and are included in “Accounts payable” in the consolidated balance sheet.

In connection with the Acquisition, the Company entered into the Advisory Agreement wherein Bain Capital provided management and consulting services and financial and other advisory services to the Company. The Advisory Agreement terminated upon consummation of the Company’s IPO in June 2014 and pursuant to the terms of the Advisory Agreement, the Company paid $23.3 million of termination fees representing acceleration of the advisory fees for the remainder of the original term. The termination fee was paid in June 2014 using the proceeds from the IPO, and was recorded as an expense within “Selling, general and administrative expenses” in the consolidated statement of operations for the year ended December 31, 2014. Bain Capital will continue to provide an immaterial level of ad hoc advisory services for the Company going forward. In conjunction with the above, we paid Bain Capital fees (including out-of-pocket expenses) of $0.1 million, $2.4 million, and $4.7million for the years ended December 31, 2015, 2014, and 2013, respectively (excluding the termination fees noted above).

Bain Capital also provides advice pursuant to a 10-year Transaction Services Agreement with fees payable equaling 1% of the transaction value of each financing, acquisition or similar transaction. In connection with the IPO, Bain Capital received $2.2 million of transaction fees, which were recorded within “Additional paid-in-capital” in the consolidated balance sheets as of December 31, 2014 (see Note 12). Bain Capital also received fees of approximately $13.9 million related to the issuance of the 2019 Senior Notes and the amendment to the 2018 Senior Secured Credit Facility in January 2013, which were included in the financing fees capitalized and included in “Deferred charges and other assets” in the consolidated balance sheet (see Note 10 for further discussion).

Total fees incurred from Bain Capital for these management and transaction advisory services were $0.1 million, $27.9 million, and $18.6 million, respectively, for the years ended December 31, 2015, 2014, and 2013.

Corporate unallocated includes corporate overhead costs, loss on extinguishment of long-term debt, and certain other income and expenses.

The primary measure of segment operating performance is EBITDA, which is defined as net income (loss) before interest, income taxes, depreciation and amortization. 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 the Company’s core operating performance. 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 EBITDA differently than the Company, and 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 the Company’s performance.

NOTE 20—RESTRUCTURING

Allyn’s Point Plant Shutdown

In September 2015, the Company approved the plan to close its Allyn’s Point latex manufacturing facility in Gales Ferry, Connecticut. This restructuring plan was a strategic business decision to improve the results of the overall Latex segment due to continuing declines in the coated paper industry in North America. Production at the facility ceased at the end of 2015, followed by decommissioning and demolition expected in 2016.

For the year ended December 31, 2015, the Company recorded restructuring charges of $6.7 million relating to the accelerated depreciation of the related assets at the Allyn’s Point facility and $0.4 million of employee termination benefit charges, which are included within “Selling, general and administrative expenses” in the consolidated statements of operations and were allocated entirely to the Latex segment.  These employee termination benefit charges remained accrued in “Accrued expenses and other current liabilities” in the consolidated balance sheet as of December 31, 2015.

The Company expects to incur approximately $0.3 million of incremental employee termination benefits charges during the first half of 2016 related to this restructuring, the majority which are expected to be paid by December 31, 2016.  Lastly, the Company expects to incur decommissioning and demolition costs associated with this plant shutdown in 2016, the cost of which will be expensed as incurred, within the Latex segment.  These costs cannot be reasonably estimated at this time.

Restructuring in Polycarbonate

During the second quarter of 2014, the Company announced a restructuring within its Basic Plastics & Feedstocks segment to exit the commodity market for polycarbonate in North America and to terminate existing arrangements with Dow regarding manufacturing services for the Company at Dow’s Freeport, Texas facility (the “Freeport facility”). The Company also entered into a new long-term supply contract with a third party to supply polycarbonate in North America. These revised arrangements became operational in the fourth quarter of 2014. In addition, the Company has executed revised supply contracts for certain raw materials that are processed at its polycarbonate manufacturing facility in Stade, Germany, which took effect January 1, 2015. These revised agreements are expected to facilitate improvements in future results of operations for the Basic Plastics & Feedstocks segment. Production at the Freeport facility ceased as of September 30, 2014, and decommissioning and demolition began thereafter, with completion in the first quarter of 2015.

For the year ended December 31, 2014, the Company recorded restructuring charges of $3.5 million relating to the accelerated depreciation of the related assets at the Freeport facility and $6.6 million in charges for the reimbursement of decommissioning and demolition costs incurred by Dow (of which $4.2 million remained accrued within “Accounts payable” on the consolidated balance sheet as of December 31, 2014). For the year ended December 31, 2015, the Company recorded the remainder of the restructuring charges of $0.5 million related to the reimbursement of decommissioning and demolition costs incurred by Dow. These charges were included in “Selling, general and administrative expenses” in the consolidated statements of operations, and were allocated entirely to the Basic Plastics & Feedstocks segment. There were no remaining amounts accrued in the consolidated balance sheet as of December 31, 2015.

Altona Plant Shutdown

In July 2013, the Company’s board of directors approved the plan to close the Company’s latex manufacturing facility in Altona, Australia. This restructuring plan was a strategic business decision to improve the results of the overall Latex segment. The facility manufactured SB latex used in the carpet and paper markets. Production at the facility ceased in the third quarter of 2013, followed by decommissioning, with demolition throughout most of 2014.

As a result of the plant closure, the Company recorded restructuring charges of $10.8 million for the year ended December 31, 2013. These charges consisted of property, plant and equipment and other asset impairment charges, employee termination benefit charges, contract termination charges, and incurred decommissioning charges.

For the year ended December 31, 2014, the Company recorded additional net restructuring charges of approximately $2.8 million, related primarily to incremental employee termination benefit charges, contract termination charges, and decommissioning costs. These charges were included in “Selling, general and administrative expenses” in

F-49

the consolidated statements of operations, and were allocated entirely to the Latex segment. There were no additional restructuring charges recorded related to the Altona plant shutdown during the year ended December 31, 2015, and no amounts remained accrued as of December 31, 2015. Of the remaining balance as of December 31, 2014, $1.2 million is recorded in “Accrued expenses and other current liabilities” and $0.9 million is recorded in “Other noncurrent liabilities” in the consolidated balance sheet.

The following tables provide a rollforward of the liability balances associated with the Altona plant shutdown for the years ended December 31, 2015 and 2014, respectively:

(a) These AOCI components are included in the computation of net periodic benefit costs (see Note 16).

NOTE 22—EARNINGS (LOSS) PER SHARE

Basic earnings (loss) per ordinary share (“basic EPS”) is computed by dividing net income (loss) available to ordinary shareholders by the weighted average number of the Company’s ordinary shares outstanding for the applicable period. Diluted earnings (loss) per ordinary share (“diluted EPS”) is calculated using net income (loss) available to ordinary shareholders divided by diluted weighted-average ordinary shares outstanding during each period, which includes unvested restricted shares. 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 EPS and diluted EPS for the years ended December 31, 2015, 2014, and 2013, respectively.

	Year Ended
	December 31,

Income (loss) per share—diluted	$	2.73	$	(1.55)	$	(0.60)

* Refer to Note 17 for discussion of restricted stock units granted in June 2014 to certain Company directors. As net loss was reported for the year ended December 31, 2014, potentially dilutive awards have not been included within the calculation of diluted EPS, as they would have an anti-dilutive effect.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Members of

Americas Styrenics LLC

The Woodlands, Texas

We have audited the accompanying consolidated balance sheets of Americas Styrenics LLC and subsidiaries (the "Company") as of December 31, 2015 and 2014, and the related consolidated statements of comprehensive income, members’ equity, and cash flows for each of the three years in the period ended December 31, 2015. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Americas Styrenics LLC and subsidiaries at December 31, 2015 and 2014, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2015, in conformity with accounting principles generally accepted in the United States of America.

AMERICAS STYRENICS LLC

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

AS OF DECEMBER 31, 2015 AND 2014, AND

FOR THE YEARS ENDED DECEMBER 31, 2015, 2014, AND 2013

(Amounts in millions of dollars)

1.FORMATION OF VENTURE

Effective May 1, 2008, Chevron Phillips Chemical Company LP (“CPChem”) and The Dow Chemical Company (“Dow”) joined forces in styrenics by creating Americas Styrenics LLC (the “Company”). Effective June 17, 2010, Dow divested its ownership in the Company to Trinseo LLC (formerly, Styron LLC). CPChem and Trinseo LLC are referred to herein as the “Members.” The Members share equally in the profits and losses of the Company.  

2.NATURE OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation—The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The Company’s subsidiaries and partnership interests are as follows: Americas Styrenics Colombia Ltda, Americas Styrenics Argentina S.R.L. (liquidated in 2013), Americas Styrenics Chile Commercial Ltda (liquidated in 2014), Americas Styrenics de Mexico, de R.L. de C.V., Americas Styrenics Canada Inc., and Americas Styrenics Industria e Comercico de Poliestireno Ltda (Brazil).  

Nature of Operations—The Company was formed as a joint venture and focuses on styrenics (styrene and polystyrene) production, sales and distribution in North America and South America.  

Cash and Cash Equivalents—Included in cash and cash equivalents, from time to time, are short-term interest-bearing investments on deposit with financial institutions. There were $33 and nil of interest bearing investments at December 31, 2015 and 2014, respectively.  

Trade Receivables—The Company’s United States’ customers are primarily in the packaging industry, but also consist of other chemical and plastics manufacturers. The Company’s foreign customers reside primarily in Argentina, Brazil, Chile, Colombia and Mexico. The Company evaluates the creditworthiness of customers and in certain circumstances, may require letters of credit to support product sales. The Company maintains an allowance for doubtful accounts based on anticipated collection of its accounts receivable.  

Inventories—Inventories at December 31, 2015 and 2014 were as follows:

	2015		2014
Finished goods	$	47.3	$	47.2
Work in process		53.2		24.6
Raw materials		24.7		30.7
Supplies		9.3		11.5
Total inventories	$	134.5	$	114.0

Inventories are stated at the lower of cost or market. Finished products and work-in-process inventories include material, labor, and manufacturing overhead costs. The reserves reducing inventories from a first-in, first-out (FIFO) basis to a last-in, first-out (LIFO) basis amounted to $24.9 at December 31, 2015, and $70 at December 31, 2014. In 2014, the liquidation of certain of the Company’s LIFO inventory layers increased operating income by $1.8. Foreign inventories are accounted for on a FIFO basis.  

F-59

Property, Plant, and Equipment—Upon formation of the Company, property, plant, and equipment were recorded at CPChem’s and Dow’s net book value. Current additions of property, plant, and equipment are recorded at cost. The Company provides for depreciation using the straight-line method at rates based on the estimated service lives of the various classes of assets (3–45 years). Expenditures for repairs and maintenance, including major maintenance commonly known as turnarounds, are expensed as incurred. Components of property, plant, and equipment at December 31, 2015 and 2014, are as follows:  

	2015		2014
Land and waterway improvements	$	10.8	$	10.8
Buildings		27.9		27.6
Transportation and construction equipment		67.4		67.8
Machinery and other equipment		855.6		830.6
Utilities and supply lines/other property		9.8		8.5
Construction in progress		10.0		27.2
Total property, plant, and equipment		981.5		972.5
Less accumulated depreciation		(727.4)		(699.7)
Net property, plant, and equipment	$	254.1	$	272.8

Income Taxes—The Company is treated as a flow-through partnership for U.S. federal income tax purposes and for most state income tax purposes. As such, the Company itself is not liable for U.S. federal income taxes. The Company files a U.S. partnership return which reflects each Member’s share of income or loss. The Members are responsible for reporting and paying any tax on their respective income tax returns. The Company is directly liable for certain state income and franchise taxes, foreign withholding, and foreign direct or indirect taxes.  

The Company has foreign subsidiaries in Argentina (liquidated in 2013), Canada, Chile (liquidated in 2014), Colombia, and Mexico. All foreign entities except the Canadian subsidiary have elected to be treated as disregarded foreign branches of the Company for U.S. purposes. As such, the income or loss of the respective disregarded entities will be included in the U.S. federal partnership return. The foreign subsidiaries are responsible for all applicable taxes on foreign operations, and these taxes have been provided for in the consolidated financial statements.  

The Company has not recorded any liabilities for uncertain tax positions.  

Impairment of Long-Lived Assets—The Company evaluates the carrying value of long-lived assets to be held and used, including intangible assets, when events or circumstances warrant such a review. The carrying value of a long-lived asset to be held and used is considered impaired when the anticipated, separately identifiable undiscounted cash flows from such an asset are less than the carrying value of the asset. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair value of the long-lived asset. Fair value is determined primarily using the anticipated cash flows discounted at a rate commensurate with the risk involved. No impairment was recorded in 2015, 2014, or 2013.  

Asset Retirement Obligation—The Company assesses whether it has legal obligations associated with the retirement of tangible long-lived assets that result from the acquisition, construction, or development and/or the normal operation of a long-lived asset, including any legal obligations that require disposal of a replaced part that is a component of a tangible long-lived asset. At December 31, 2015 and 2014, the Company had no significant asset retirement obligations.  

Insurance —The Company maintains insurance for automobile risks, general liability including products, directors, officers, workers’ compensation, and property. This insurance is placed with highly rated insurance carriers. The limits and deductibles are consistent for a company of this size and structure.  

Foreign Currency—The functional currency for the Company’s foreign operations is the U.S. dollar, resulting in no currency translation adjustments. Foreign currency gains and losses are reflected in operations.  

Use of Estimates—The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent

F-60

assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.  

Revenue Recognition—The Company recognizes revenue when there is evidence of a sales agreement, the delivery of goods has occurred, the sales price is fixed or determinable, and the collectability of revenue is reasonably assured. Revenue includes the selling price of the product and all related delivery charges paid by the customer. Freight costs and any directly related associated costs of transporting finished product to customers are recorded as “cost of sales.” Revenue is reduced at the time of sale for estimated customer-related incentives (mostly volume-related incentives).  

Subsequent Events—The Company has evaluated subsequent events through the date the financial statements were available to be issued as of February 26, 2016.  

3.RECENT ACCOUNTING GUIDANCE

In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers.  The objective of ASU No. 2014-09 is to clarify the principles for recognizing revenue and to develop a common revenue standard for U.S. GAAP and International Financial Reporting Standards.  In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers: Deferral of the Effective Date, which deferred the effective date of ASU No. 2014‑09 for one year.  ASU No. 2014-09 is now effective for fiscal years beginning after December 15, 2018.  The standards permit retrospective application using either of the following methodologies: (i) restatement of each prior reporting period presented or (ii) recognition of a cumulative-effect adjustment as of the date of initial application.  The Company is currently evaluating the impact of adopting ASU No. 2014‑09, including the transition method to be applied.

In July 2015, the FASB issued ASU No. 2015-11, Simplifying the Measurement of Inventory.  This ASU requires entities to measure most inventory at the lower of cost and net realizable value, thereby simplifying the current guidance under which an entity must measure inventory at the lower of cost or market.  ASU No. 2015-11 is effective for fiscal years beginning after December 15, 2016, and should be applied prospectively.  Early adoption is permitted.  The Company is currently evaluating the impact of adopting ASU No. 2015-11.

In November 2015, the FASB issued ASU No. 2015-17, Balance Sheet Classification of Deferred Taxes.  The objective of this ASU is to simplify the financial statement presentation of deferred taxes by presenting both current and noncurrent deferred tax assets and liabilities as noncurrent on the balance sheet.  ASU No. 2015-17 is effective for fiscal years beginning after December 15, 2017.  This standard may be applied either prospectively or retrospectively to all periods presented, and early adoption is permitted.  The Company adopted ASU No. 2015-17 as of December 31, 2015 on a retrospective basis.  As a result, $0.6 of deferred income tax previously included within current assets were reclassified to noncurrent in the Company’s consolidated balance sheet as of December 31, 2014.  

4.REVOLVING CREDIT FACILITY

The Company’s unsecured $50 revolving credit facility with Comerica Bank terminates in August 2020. At the Company’s option, the interest rate under this facility equals either the prime or the London InterBank Offered Rate based rate as defined in the credit agreement.  

There were no outstanding borrowings at December 31, 2015 or 2014.

F-61

5.INCOME TAXES

The components of the income before taxes for the years ended December 31, 2015, 2014, and 2013, are as follows:

	2015		2014		2013
Domestic	$	240.3	$	59.3	$	35.5
Foreign		3.5		5.9		4.8
Total income before taxes	$	243.8	$	65.2	$	40.3

The components of income tax expense for the years ended December 31, 2015, 2014, and 2013, are as follows:

	2015		2014
Fixed assets	$	2.2	$	1.8
Other temporary differences		0.6		0.6
Deferred tax assets	$	2.8	$	2.4

Undistributed earnings of foreign subsidiaries are not deemed to be permanently reinvested. Currently, undistributed earnings exist in the Canadian, Colombian, and Mexican subsidiaries. Future repatriation of earnings will not be subject to tax by the Company (but rather its Members); however, foreign withholding taxes may apply.  

6.EMPLOYEE BENEFIT PLANS

The Company provides reimbursement of medical and dental costs to retired employees. The Company’s plan, the Retiree Reimbursement Account (RRA), is funded at the time of the employee’s retirement based on years of credited service. Thereafter, the Company is not obligated to make additional contributions. The Company has the ability to change the benefits at any time. All employees are eligible, except for former Dow employees who choose to participate in The Dow Chemical Company Retiree Medical Care Program upon retirement. The Company uses a December 31 measurement date for the RRA.

At December 31, 2015 and 2014, the RRA had benefit obligations in the amount of $17.7 and $16.5, respectively. The Company contributed and paid benefits in the amount of $0.4 in 2015, $0.4 in 2014, and $0.3 in 2013.

At December 31, 2015 and 2014, amounts recognized in the consolidated balance sheets consist of:  

	2015		2014
Current liabilities	$	(0.6)	$	(0.5)
Noncurrent liabilities		(17.1)		(16.0)
Total	$	(17.7)	$	(16.5)

F-62

At December 31, 2015 and 2014, amounts recognized in accumulated other comprehensive loss were as follows:

	2015		2014
Net actuarial loss	$	2.4	$	1.9
Prior service cost		3.4		4.1
Total	$	5.8	$	6.0

In 2016, $0.7 of estimated prior service cost will be amortized from accumulated other comprehensive loss into net periodic benefit cost.

Net periodic benefit cost and components of other amounts recognized in other comprehensive (income) loss were as follows:  

	2015		2014		2013
Net periodic postretirement benefit cost	$	1.8	$	1.8	$	1.8
Other changes in benefit obligations recognized in other comprehensive loss (income):
Net actuarial loss (gain)		0.5		1.2		(1.3)
Recognized actuarial loss		—		—		(0.1)
Recognized prior-service cost		(0.7)		(0.7)		(0.7)
Total recognized in other comprehensive (income) loss		(0.2)		0.5		(2.1)
Total recognized in net periodic benefit cost and other comprehensive loss (income)	$	1.6	$	2.3	$	(0.3)

Actuarial assumptions used to determine benefit obligations and net periodic benefit cost were as follows:

	2015		2014		2013
Discount rate used to determine net periodic benefit cost	3.65	%	4.27	%	3.44	%
Discount rate used to determine benefit obligation at December 31	3.76	%	3.65	%	N/A

	2015		2014		2013
Health Care Cost Assumptions
Initial health care cost trend rate	8.00	%	8.50	%	9.00	%
Ultimate health care cost trend rate	4.50	%	4.50	%	4.50	%
Year ultimate reached	2023		2023		2022

Estimated health care cost trend rates can have a significant effect on the amounts reported for the RRA.  

The Company expects to contribute approximately $0.6 to its RRA plan in 2016.  

At December 31, 2015, the estimated future benefit payments, reflecting expected future service, as appropriate, are expected to be paid as follows:  

2016	$	0.6
2017		0.9
2018		1.0
2019		1.3
2020		1.5
2021 through 2025		9.5
Total	$	14.8

F-63

The Company also has a defined contribution employee savings plan and made discretionary contributions of $3.5, $3.4, and $3.2 in 2015, 2014, and 2013, respectively.  

7. COMMITMENTS AND CONTINGENCIES

COMMITMENTS

The Company and its subsidiaries maintain outside service agreements and lease buildings, ground and easements, rail cars, and other vehicles under noncancelable operating leases, which expire on varying dates between 2016 and 2028.  

Total future minimum annual rentals in effect at December 31, 2015, for noncancelable operating leases are as follows:  

Years Ending December 31
2016	$	8.4
2017		6.5
2018		4.4
2019		1.9
2020		1.7
2021 and thereafter		8.8
Total	$	31.7

Expense for total rental and long-term commitments was $7.6, $9.4, and $23.8 for the years ended December 31, 2015, 2014, and 2013, respectively.  

The Company has entered into long-term sales commitments and purchase agreements with several of its key suppliers, including its Members (see Note 8). The commitment contracts are for one- to three-year periods with some cost efficiency incentives. Because the pricing and supply fluctuates with the commodity market, a definitive dollar value cannot be determined.  

In addition, the Company has purchase commitments of $27.7 mainly related to certain feedstock, utility and capital projects costs. The Company does not consider purchase orders to be firm commitments. If the Company chooses to cancel a purchase order, it may be obligated to reimburse the vendor for unrecoverable outlays incurred prior to cancellation under certain circumstances.  

CONTINGENCIES

The Company is cooperating with a confidential subpoena dated May 11, 2015, from the U.S. Postal Service in coordination with the U.S. Department of Justice seeking information relating to the polystyrene market. The Company has conducted an internal review and is unaware of any improper activity. The Company has appointed a Litigation Management Committee among its Board of Directors to provide oversight to the matter.  At this time, it is premature for the Company to determine whether it is probable that a loss will occur, nor is the Company able to estimate a range of potential loss. Therefore, a liability has not been recorded with respect to this matter.

The Company is a party to various legal proceedings and claims incidental to the normal conduct of its business. Management believes that the ultimate disposition of these matters will not have a material adverse effect on the Company’s consolidated financial position or results of operations.  

Pursuant to the contribution agreement, all preexisting environmental matters have been outlined for each site and any contingencies are the responsibility of Dow and CPChem. All subsequent obligations are the liability of the Company. No environmental reserve was recorded as of December 31, 2015, 2014, or 2013. During 2015, the Company received reimbursement from Dow of certain capital costs at one of its polystyrene facilities, totaling $7.8, which was recorded as a reduction of the carrying cost of the assets.  

F-64

8.RELATED-PARTY TRANSACTIONS

The Company entered into various supply and purchase agreements with the Members and their affiliated companies. These agreements include sales and purchases of energy, raw materials, and services. A summary of transactions for the years ended December 31, 2015, 2014, and 2013, is as follows:  

	2015		2014		2013
Net sales	$	161.4	$	263.0	$	255.1
Purchases		483.3		847.0		980.6

Balances receivable and payable to the Members are included in the December 31, 2015 and 2014 consolidated balance sheets as related company receivables and payables.

NOW, THEREFORE, in consideration of the foregoing, of the mutual promises contained herein and of other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

1.POSITION AND DUTIES.

(a)During the Employment Term (as defined in Section 2 hereof), the Executive shall serve as Senior Vice President and Chief Legal Officer of the Company and shall be a member of the Company’s Executive Leadership Team. In this capacity, the Executive shall have the duties, authorities and responsibilities commensurate with the duties, authorities and responsibilities of persons in similar capacities in similarly sized companies, and such other executive duties, authorities and responsibilities as may reasonably be assigned to the Executive that are not inconsistent with the Executive’s position as Senior Vice President and Chief Legal Officer of the Company.  The Executive’s principal place of employment with the Company shall be in the Philadelphia, Pennsylvania metropolitan area.  The Executive shall report directly tothe Company’s Chief Executive Officer.

(b)During the Employment Term, the Executive shall devote all of the Executive’s business time, energy, business judgment, knowledge and skill and the Executive’s reasonable best efforts to the performance of the Executive’s duties with the Company, provided that the foregoing shall not prevent the Executive from (i) serving on the boards of directors of non-profit organizations and, with the prior written approval of the Board, other for profit companies, (ii) participating in charitable, civic, educational, professional, community or industry affairs, and (iii) managing the Executive’s passive personal investments so long as such activities, individually or in the aggregate, do not violate Section 10 hereof, interfere or conflict with the Executive’s duties hereunder or otherwise create a business or fiduciary conflict.

2.EMPLOYMENT TERM.  The Company agrees to employ the Executive pursuant to the terms of this Agreement, and the Executive agrees to be so employed, for a term of three (3)

1

years (the “Initial Term”) commencing upon January 1, 2015 (the “Effective Date”).  On the third anniversary of the Effective Date and each annual anniversary thereafter, the term of this Agreement shall be automatically extended for successive one-year periods, provided,  however, that either party hereto may elect not to extend this Agreement by giving written notice to the other party at least ninety (90) days prior to any such anniversary date.  Notwithstanding the foregoing, the Executive’s employment hereunder may be earlier terminated in accordance with Section 6 hereof, subject to Section 7 hereof.  The period of time between the Effective Date and the termination of the Executive’s employment hereunder shall be referred to herein as the “Employment Term.”

3.BASE SALARY.  The Company agrees to pay the Executive a base salary for calendar year 2015 at an annual rate of not less than $365,000, payable in accordance with the regular payroll practices of the Company, but not less frequently than monthly.  The Executive’s base salary shall be subject to annual review by the Board (or a committee thereof) during the first ninety (90) days of each calendar year, and the base salary in respect of such calendar year may be increased above, but not decreased below, its level for the preceding calendar year, by the Board.  The base salary as determined herein and adjusted from time to time shall constitute “Base Salary” for purposes of this Agreement.

4.ANNUAL BONUS. During the Employment Term, the Executive shall be eligible for an annual cash performance bonus (an “Annual Bonus”) in respect of each calendar year that ends during the Employment Term, to the extent earned based on performance against objective performance criteria.  The performance criteria for any particular calendar year shall be determined in good faith by the Board, no later than ninety (90) days after the commencement of such calendar year.  The Executive’s targeted Annual Bonus for a calendar year shall equal55% of the Executive’s Base Salary for such calendar year (the “Target Bonus”) if target levels of performance for such year are achieved, with greater or lesser amounts (including zero) paid for performance above and below target (such greater and lesser amounts to be determined by a formula established by the Board for such year when it establishes the targets and performance criteria for such year); provided that the Executive’s maximum Annual Bonus for any calendar year during the Employment Term shall equal 200% of the Target Bonus for such calendar year.  The Executive’s Annual Bonus for a calendar year shall be determined by the Board after the end of the applicable calendar year based on the level of achievement of the applicable performance criteria, and shall be paid to the Executive in the calendar year following the calendar year to which such Annual Bonus relates at the same time annual bonuses are paid to other senior executives of the Company, subject to continued employment at the time of payment (except as otherwise provided in Section 7 hereof).

5.EMPLOYEE BENEFITS.

2

extent such plans are duplicative of the benefits otherwise provided hereunder.  The Executive’s participation in any such employee benefit plan shall be subject to the terms of the applicable plan documents and generally applicable Company policies.  Notwithstanding the foregoing, the Company may modify or terminate any employee benefit plan at any time, if and to the extent allowed pursuant to the terms of such plan, provided that any such amendment may have no more adverse effect on the Executive than on any other participant in such plan.  The Company may provide perquisites to the Executive at the discretion of the Board.

(b)VACATIONS.  During the Employment Term, the Executive shall be entitled to twenty-seven (27) days of paid vacation per calendar year (pro-rated for partial years) in accordance with the Company’s policy on accrual and use applicable to employees as in effect from time to time.

(c)BUSINESS EXPENSES.  Upon presentation of reasonable substantiation and documentation as the Company may specify from time to time, the Executive shall be reimbursed in accordance with the Company’s expense reimbursement policies as in effect from time to time, for all reasonable out-of-pocket business expenses incurred and paid by the Executive during the Employment Term and in connection with the performance of the Executive’s duties hereunder.

Payments and benefits provided in this Section 7(d) shall be in lieu of any termination or severance payments or benefits for which the Executive may be eligible under any of the plans, policies or programs of the Company or under the Worker Adjustment Retraining Notification Act of 1988 or any similar state statute or regulation.

6

(f)CODE SECTION 280G.

(i)Change in Control Prior to Publicly Traded Equity of Company.  So long as the Company is described in Section 280G(b)(5)(A)(ii)(I) of the Code, in the event that any payment that is either received by the Executive or paid by the Company on the Executive’s behalf or any property, or any other benefit provided to the Executive under the Agreement or under any other plan, arrangement or agreement with the Company or any other person whose payments or benefits are treated as contingent on a change of ownership or control of the Company (or in the ownership of a substantial portion of the assets of the Company) or any person affiliated with the Company or such person (but only if such payment or other benefit is in connection with the Executive’s employment by the Company) (collectively the “Company Payments”), would be subject to the tax imposed by Section 4999 of the Code (and any similar tax that may hereafter be imposed by any taxing authority) (the “Excise Tax”), the Company shall, with respect to such Company Payments, use its reasonablebest efforts to obtain a vote satisfying the requirements of Section 280G(b)(5) of the Code, such that no portion of the Company Payments will be subject to such Excise Tax.  In the event that a vote satisfying the requirements of Section 280G(b)(5) of the Code is not obtained for any reason, then the Executive will be entitled to receive a portion of the Company Payments having a value equal to $1 less than three (3) times the Executive’s “base amount” (as such term is defined in Section 280G(b)(3)(A) of the Code) (the “Safe Harbor Amount”).  Any reduction of the Company Payments pursuant to the foregoing shall occur in the following order:  (A) any cash severance payable by reference to the Executive’s Base Salary or Annual Bonus; (B) any other cash amount payable to the Executive; (C) any benefit valued as a “parachute payment;” and (D) acceleration of vesting of any equity award.

(ii)Change in Control Upon or Following Publicly Traded Equity of Company.  In the event that Company Payments become payable to the Executive during any period in which the Company is not an entity described in Section 280G(b)(5)(A)(ii)(I) of the Code, if the Company Payments will be subject to the Excise Tax, then the Executive will be entitled to receive either (A) the full amount of the Company Payments, or (B) a portion of the Company Payments having a value equal to the Safe Harbor Amount, whichever of clauses (A) and (B), after taking into account applicable federal, state, and local income taxes and the Excise Tax, results in the receipt by the Executive on an after-tax basis, of the greatest portion of the Company Payments.  Any reduction of the Company Payments pursuant to the foregoing shall occur in the same manner as provided in the last sentence of Section 7(f)(i) hereof.

(iii)Accountants.  Any determination required under this Section 7(f) shall be made in writing by the independent public accountants of the Company, whose determination shall be conclusive and binding for all purposes upon the Company and the Executive.  For purposes of making any calculation required by this Section 7(f), such accountants may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good-faith interpretations concerning the application of Sections 280G and 4999 of the Code.

8.OTHER OBLIGATIONS.  Upon any termination of the Executive’s employment with the Company, the Executive shall promptly resign from any other position as an officer, director or fiduciary of the Company, Parent and any  Affiliate.

7

9.RELEASE; NO MITIGATION; NO SET-OFF.  Any and all amounts payable and benefits or additional rights provided pursuant to this Agreement beyond the Accrued Benefits (other than the amount described in Section 7(a)(iii) hereof) shall only be payable if the Executive delivers to the Company and does not revoke a general release of claims in favor of the Company in substantially the form of Exhibit A attached hereto.  Such release shall be executed and delivered (and no longer subject to revocation, if applicable) within sixty (60) days following termination.  In no event shall the Executive be obligated to seek other employment or take any other action by way of mitigation of the amounts payable to the Executive under any of the provisions of this Agreement, nor shall the amount of any payment hereunder be reduced by any compensation earned by the Executive as a result of employment by a subsequent employer (except as provided in Section 7(d)(iii) hereof).  The Company’s obligations to pay the Executive amounts hereunder shall not be subject to set-off, counterclaim or recoupment of amounts owed by the Executive to the Company or any of its affiliates.

10.RESTRICTIVE COVENANTS.

(a)CONFIDENTIALITY.  During the course of the Executive’s employment with the Company, the Executive will learn confidential information regarding the Company.  The Executive agrees that the Executive shall not, directly or indirectly, use, make available, sell, disclose or otherwise communicate to any person, other than in the course of the Executive’s assigned duties and for the benefit of the Company, either during the period of the Executive’s employment or at any time thereafter, any business and technical information or trade secrets, nonpublic, proprietary or confidential information, knowledge or data relating to the Company or any of its Affiliates, or received from third parties subject to a duty on the Company’s and its Affiliates’ part to maintain the confidentiality of such information and to use it only for certain limited purposes, in each case which shall have been obtained by the Executive during the Executive’s employment by the Company.  The foregoing shall not apply to information that (i) was known to the public prior to its disclosure to the Executive; (ii) becomes generally known to the public subsequent to disclosure to the Executive through no wrongful act of the Executive or any representative of the Executive; or (iii) the Executive is required to disclose by applicable law, regulation or legal process (provided that the Executive provides the Company with prior notice of the contemplated disclosure and cooperates with the Company at its expense in seeking a protective order or other appropriate protection of such information).  The terms and conditions of this Agreement shall remain strictly confidential, and the Executive hereby agrees not to disclose the terms and conditions hereof to any person or entity, other than immediate family members, legal advisors or personal tax or financial advisors, or prospective future employers solely for the purpose of disclosing the limitations on the Executive’s conduct imposed by the provisions of this Section 10 who, in each case, shall be instructed by the Executive to keep such information confidential.

(b)NONCOMPETITION.The Executive acknowledges that the Executive performs services of a unique nature for the Company that are irreplaceable, and that the Executive’s performance of such services to a competing business will result in irreparable harm to the Company.  Accordingly, during the Executive’s employment hereunder and for a period of one (1) year thereafter, the Executive agrees that the Executive will not, directly or indirectly, own, manage, operate, control, be employed by (whether as an employee, consultant, independent contractor or otherwise, and whether or not for compensation) or render services to any person,

8

firm, corporation or other entity, in whatever form, engaged in competition with any material business of the Company  or any Affiliate or in any other material business in which the Company  or any Affiliate  has taken material steps and has material plans, on or prior to the date or termination, to be engaged in on or after such date, in any locale of any country in which the Company or such Affiliate conducts business.  Notwithstanding the foregoing, nothing herein shall prohibit the Executive from being a passive owner of not more than one percent (1%) of the equity securities of a publicly traded corporation engaged in a business that is in competition with the Company or any of its affiliates, so long as the Executive has no active participation in the business of such corporation.

(c)NONSOLICITATION; NONINTERFERENCE.  During the Executive’s employment with the Company and for a period of one (1) year thereafter, the Executive agrees that the Executive shall not, except in the furtherance of the Executive’s duties hereunder, directly or indirectly, individually or on behalf of any other person, firm, corporation or other entity, (i) solicit, aid or induce any customer of the Company or an Affiliate to purchase goods or services then sold by the Company or any Affiliate from another person, firm, corporation or other entity or assist or aid any other persons or entity in identifying or soliciting any such customer, (ii) solicit, aid or induce any employee, representative or agent of the Company or any Affiliate to leave such employment or retention or, in the case of employees, to accept employment with or render services to or with any other person, firm, corporation or other entity unaffiliated with the Company or any Affiliate, or hire or retain any such employee, or take any action to materially assist or aid any other person, firm, corporation or other entity in identifying, hiring or soliciting any such employee, or (iii) interfere, or aid or induce any other person or entity in interfering, with the relationship between the Company or any Affiliate and any of their respective vendors, joint venturers or licensors.  An employee, representative or agent shall be deemed covered by this Section 10(c) while so employed or retained and for a period of six (6) months thereafter.  Notwithstanding the foregoing, the provisions of this Section 10(c) shall not be violated by general advertising or solicitation not specifically targeted at Company or Affiliate-related individuals or entities.

(d)INVENTIONS.(i)  The Executive acknowledges and agrees that all ideas, methods, inventions, discoveries, improvements, work products, developments or works of authorship (“Inventions”), whether patentable or unpatentable, (A) that relate to the Executive’s work with the Company, made or conceived by the Executive, solely or jointly with others, during the Employment Term, or (B) suggested by any work that the Executive performs in connection with the Company, either while performing the Executive’s duties with the Company or on the Executive’s own time, shall belong exclusively to the Company (or its designee), whether or not patent applications are filed thereon.  The Executive will keep full and complete written records (the “Records”), in the manner prescribed by the Company, of all Inventions, and will promptly disclose all Inventions completely and in writing to the Company.  The Records shall be the sole and exclusive property of the Company, and the Executive will surrender them upon the termination of the Employment Term, or upon the Company’s request.  The Executive will assign to the Company the Inventions and all patents that may issue thereon in any and all countries, whether during or subsequent to the Employment Term, together with the right to file, in the Executive’s name or in the name of the Company (or its designee), applications for patents and equivalent rights (the “Applications”).  The Executive will, at any time during and subsequent to the Employment Term, make such applications, sign such papers, take all rightful oaths, and

9

perform all acts as may be requested from time to time by the Company with respect to the Inventions.  The Executive will also execute assignments to the Company (or its designee) of the Applications, and give the Company and its attorneys all reasonable assistance (including the giving of testimony) to obtain the Inventions for the Company’s benefit, all without additional compensation to the Executive from the Company.

(ii)In addition, the Inventions will be deemed Work for Hire, as such term is defined under the copyright laws of the United States, on behalf of the Company and the Executive agrees that the Company will be the sole owner of the Inventions, and all underlying rights therein, in all media now known or hereinafter devised, throughout the universe and in perpetuity without any further obligations to the Executive.  If the Inventions, or any portion thereof, are deemed not to be Work for Hire, the Executive hereby irrevocably conveys, transfers and assigns to the Company, all rights, in all media now known or hereinafter devised, throughout the universe and in perpetuity, in and to the Inventions, including, without limitation, all of the Executive’s right, title and interest in the copyrights (and all renewals, revivals and extensions thereof) to the Inventions, including, without limitation, all rights of any kind or any nature now or hereafter recognized, including, without limitation, the unrestricted right to make modifications, adaptations and revisions to the Inventions, to exploit and allow others to exploit the Inventions and all rights to sue at law or in equity for any infringement, or other unauthorized use or conduct in derogation of the Inventions, known or unknown, prior to the date hereof, including, without limitation, the right to receive all proceeds and damages therefrom.  In addition, the Executive hereby waives any so-called “moral rights” with respect to the Inventions. To the extent that the Executive has any rights in the results and proceeds of the Inventions that cannot be assigned in the manner described herein, the Executive agrees to unconditionally waive the enforcement of such rights.  The Executive hereby waives any and all currently existing and future monetary rights in and to the Inventions and all patents that may issue thereon, including, without limitation, any rights that would otherwise accrue to the Executive’s benefit by virtue of the Executive being an employee of or other service provider to the Company.

(e)NON-DISPARAGEMENT. The Executive hereby covenants to the Company and agrees that the Executive shall not, directly or indirectly, make or solicit or encourage others to make or solicit any disparaging remarks concerning any member of the Company or an Affiliate or any of their current or former officers, directors, employees, products, services, businesses or activities; provided that the foregoing shall not be violated by good faith statements made by the Executive in connection with the Executive’s review of the performance of officers or other service providers of the Company or an Affiliate.  Notwithstanding the foregoing, nothing herein shall prohibit or restrict the Executive from providing statements or information that the Executive believes in good faith to be necessary or advisable in connection with any legal proceeding or investigation conducted by or at the behest of the Company, any governmental authority or quasi-governmental authority.

(f)RETURN OF COMPANY PROPERTY.  On the date of the Executive’s termination of employment with the Company for any reason (or at any time prior thereto at the Company’s request), the Executive shall return all property belonging to the Company or its Affiliates (including, but not limited to, any Company-provided laptops, computers, cell phones, wireless electronic mail devices or other equipment, or documents and property belonging to the

10

Company).  The Executive may retain the Executive’s rolodex and similar address books provided that such items only include contact information.

(g)REASONABLENESS OF COVENANTS.  In signing this Agreement, the Executive gives the Company assurance that the Executive has carefully read and considered all of the terms and conditions of this Agreement, including the restraints imposed under this Section 10.  The Executive agrees that these restraints are necessary for the reasonable and proper protection of the Company and its Affiliates and their trade secrets and confidential information and that each and every one of the restraints is reasonable in respect to subject matter, length of time and geographic area, and that these restraints, individually or in the aggregate, will not prevent the Executive from obtaining other suitable employment during the period in which the Executive is bound by the restraints.  The Executive acknowledges that each of these covenants has a unique, very substantial and immeasurable value to the Company and its Affiliates and that the Executive has sufficient assets and skills to provide a livelihood while such covenants remain in force.  The Executive further covenants that the Executive will not challenge the reasonableness or enforceability of any of the covenants set forth in this Section 10, other than in response to an attempt by the Company or an Affiliate to enforce such covenants against the Executive.  It is also agreed that the Affiliates will have the right to enforce all of the Executive’s obligations to such Affiliates under this Agreement, including without limitation pursuant to this Section 10.

(h)REFORMATION.  If any provision of this Section 10 is ever deemed to exceed the time, geographic area or activity limitations that applicable law permits, the Executive and the Company agree to reduce such limitations to the maximum permissible limitation, and the Executive and the Company authorize a court or arbitrator having jurisdiction to reform each such provision to the maximum time, geographic area or activity limitations that applicable law permits, provided, however, that such reductions shall apply only with respect to the operation of such provision in the particular jurisdiction in which such adjudication is made.

(i)TOLLING.  In the event of any violation of the provisions of this Section 10, the Executive acknowledges and agrees that the post-termination restrictions contained in this Section 10 shall be extended by a period of time equal to the period of such violation, it being the intention of the parties hereto that the running of the applicable post-termination restriction period shall be tolled during any period of such violation.

(j)SURVIVAL OF PROVISIONS.  The obligations contained in Sections 10 and 11 hereof shall survive the termination or expiration of the Employment Term and the Executive’s employment with the Company and shall be fully enforceable thereafter.

11.COOPERATION.  Upon the receipt of reasonable notice from the Company (including through outside counsel), the Executive agrees that while employed by the Company and thereafter (to the extent it does not materially interfere with the Executive’s employment or other business activities after employment by the Company), the Executive will respond and provide information with regard to matters in which the Executive has knowledge as a result of the Executive’s employment with the Company, and will provide reasonable assistance to the Company, the Affiliates and their respective representatives in defense of all claims that may be made against the Company or the Affiliates, and will assist the Company and the Affiliates in the prosecution of all claims that may be made by the Company or the Affiliates, to the extent that

11

such claims may relate to the period of the Executive’s employment with the Company.  The Executive also agrees to promptly inform the Company (to the extent that the Executive is legally permitted to do so) if the Executive is asked to assist in any investigation of the Company or the Affiliates (or their actions), regardless of whether a lawsuit or other proceeding has then been filed against the Company or Affiliates with respect to such investigation, and shall not do so unless legally required.  Upon presentation of appropriate documentation, the Company shall pay or reimburse the Executive for all reasonable out-of-pocket travel, duplicating, telephonic, counsel and other expenses incurred by the Executive in complying with this Section 11.

12.EQUITABLE RELIEF AND OTHER REMEDIES.The Executive acknowledges and agrees that the Company’s remedies at law for a breach or threatened breach of any of the provisions of Section 10 hereof or Section 11 hereof would be inadequate and, in recognition of this fact, the Executive agrees that, in the event of such a breach or threatened breach, in addition to any remedies at law, the Company shall be entitled to obtain equitable relief in the form of specific performance, a temporary restraining order, a temporary or permanent injunction or any other equitable remedy which may then be available.  In the event of a Material Covenant Violation or a Material Cooperation Violation by the Executive, any severance being paid to the Executive pursuant to this Agreement or otherwise shall immediately cease.

13.NO ASSIGNMENTS.This Agreement is personal to each of the parties hereto.  Except as provided in this Section 13 hereof, no party may assign or delegate any rights or obligations hereunder without first obtaining the written consent of the other party hereto.  The Company shall assign this Agreement to any successor to all or substantially all of the business and/or assets of the Company or Parent, provided that the Company shall require such successor to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place, and provided that the Company agrees to perform such obligations if such successor fails to do so in a timely manner.  As used in this Agreement, “Company” shall mean the Company and any successor to all or substantially all of its business and/or assets, which assumes and agrees to perform the duties and obligations of the Company under this Agreement by operation of law or otherwise.

14.NOTICES. For purposes of this Agreement, notices and all other communications provided for in this Agreement shall be in writing and shall be deemed to have been duly given (a) on the date of delivery, if delivered by hand, (b) on the date of transmission, if delivered by confirmed facsimile or electronic mail, (c) on the first business day following the date of deposit, if delivered by guaranteed overnight delivery service, or (d) on the fourth business day following the date delivered or mailed by United States registered or certified mail, return receipt requested, postage prepaid, addressed as follows:

or to such other address as either party may have furnished to the other in writing in accordance herewith, except that notices of change of address shall be effective only upon receipt.

15.SECTION HEADINGS; INCONSISTENCY.The section headings used in this Agreement are included solely for convenience and shall not affect, or be used in connection with, the interpretation of this Agreement.  In the event of any inconsistency between the terms of this Agreement (including the Exhibits hereto) and any form, award, plan or policy of the Company, the terms of this Agreement shall govern and control.

16.SEVERABILITY.  The provisions of this Agreement shall be deemed severable and the invalidity or unenforceability of any provision shall not affect the validity or enforceability of the other provisions hereof. If the final determination of an arbitrator or a court of competent jurisdiction declares, after the expiration of the time within which judicial review (if permitted) of such determination may be perfected, that any term or provision of this Agreement is invalid or unenforceable, the remaining terms and provisions will be unimpaired, and the invalid or unenforceable term or provision will be deemed replaced by a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision. Any prohibition or finding of unenforceability as to any provision of this Agreement in any one jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

17.COUNTERPARTS.  This Agreement may be executed in several counterparts, each of which shall be deemed to be an original but all of which together will constitute one and the same instrument.

18.INDEMNIFICATION.  The Company hereby agrees to indemnify the Executive and hold the Executive harmless to the fullest extent allowable under applicable law  against and in respect of any and all actions, suits, proceedings, claims, demands, judgments, costs, expenses (including attorney’s fees, and the advancement of such fees subject to any legally required repayment undertaking), losses, and damages resulting from the Executive’s performance of the Executive’s duties and obligations with the Company.  This obligation shall survive the termination of the Executive’s employment with the Company.

19.LIABILITY INSURANCE.  The Company shall cover the Executive under directors’ and officers’ liability insurance both during and, while potential liability exists, after the Employment Term in the same amount and to the same extent as the Company covers its other officers and directors.

20.GOVERNING LAW.  This Agreement, the rights and obligations of the parties hereto, and any claims or disputes relating thereto, shall be governed by and construed in

13

accordance with the laws of the State of Delaware (but not including any choice of law rule thereof that would cause the laws of another jurisdiction to apply).

21.ARBITRATION. 

(a)Any dispute or controversy arising under or in connection with this Agreement or the Executive’s employment relationship with the Company, irrespective of whether this Agreement or the Executive’s employment relationship with the Company has terminated, will be settled exclusively by confidential, binding arbitration to be seated in Philadelphia, Pennsylvania and conducted in accordance with the Employment Arbitration Rules and Mediation Procedures of the American Arbitration Association (“AAA”), as then in effect.  The AAA will appoint a single, neutral arbitrator from a panel of former or retired judges to preside over the arbitration and resolve the dispute. Other than as set forth in Section 10(h), the arbitrator will not have the authority to add to, detract from or modify any provision of this Agreement or to award punitive damages to any injured party. Judgment may be entered on the arbitrator’s award in any court having jurisdiction. Each party will bear its own expenses and legal fees in any arbitration.

(b)Notwithstanding the foregoing, each party shall be entitled to seek injunctive or other equitable relief, as contemplated by Section 12, from any court of competent jurisdiction, without the need to resort to arbitration.

(c)The Company and the Executive shall keep the existence and contents of the arbitration strictly confidential, other than as required by applicable law.

22.MISCELLANEOUS.  No provision of this Agreement may be modified, waived or discharged unless such waiver, modification or discharge is agreed to in writing and signed by the Executive and such officer or director as may be designated by the Board.  No waiver by either party hereto at any time of any breach by the other party hereto of, or compliance with, any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time.  This Agreement together with all exhibits hereto sets forth the entire agreement of the parties hereto in respect of the subject matter contained herein and supersedes any and all prior agreements or understandings between the Executive and the Company with respect to the subject matter hereof, whether written or oral.  No agreements or representations, oral or otherwise, express or implied, with respect to the subject matter hereof have been made by either party which are not expressly set forth in this Agreement.

23.REPRESENTATIONS; ACTIONS BY PRIOR EMPLOYERS.  The Executive represents and warrants to the Company that (a) the Executive has used the Executive’s best efforts to provide the Company with (i) each agreement with a predecessor employer which may have any bearing on the Executive’s legal right to enter into this Agreement and to perform all of the obligations on the Executive’s part to be performed hereunder in accordance with its terms, or (ii) a summary of the applicable provisions of each such agreement which the Executive may not provide to the Company due to an existing confidentiality obligation, and (b) other than the agreements referenced in the preceding clause (a), the Executive is not a party to any agreement or understanding, whether written or oral, and is not subject to any restriction (including, without

14

limitation, any non-competition restriction from a prior employer), which, in either case, could prevent the Executive from entering into this Agreement or performing all of the Executive’s duties and obligations hereunder.  The Executive understands that the foregoing representations are a material inducement to the Company entering into this Agreement, and to the extent that either of such representations is untrue in any material respect at any time or for any reason, this Agreement shall be voidable by the Company such that the parties hereunder shall be relieved of all of their respective duties and obligations hereunder; provided that any termination of the Executive’s employment resulting from the Company exercising its rights pursuant to this sentence shall be treated as a termination of employment by the Executive without Good Reason.  If any prior employer of the Executive, or any affiliate of any such prior employer, challenges the Executive’s right to enter into this Agreement and to perform all of the Executive’s obligations hereunder (whether by action against the Executive, the Company, Parent and/or an Affiliate), the Company, Parent (on behalf of itself and all Affiliates) and the Executive each agree to use their reasonable best efforts to defend against such challenge.

24.TAX MATTERS.

(a)WITHHOLDING.  The Company may withhold from any and all amounts payable under this Agreement or otherwise such federal, state and local taxes as may be required to be withheld pursuant to any applicable law or regulation.

(b)SECTION 409A COMPLIANCE.

(i)The intent of the parties is that payments and benefits under this Agreement comply with Section 409A of the Code and the regulations and guidance promulgated thereunder (collectively “Code Section 409A”) and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted to be in compliance therewith.  To the extent that any provision hereof is modified in order to comply with Code Section 409A, such modification shall be made in good faith and shall, to the maximum extent reasonably possible, maintain the original intent and economic benefit to the Executive and the Company of the applicable provision without violating the provisions of Code Section 409A.  Any such modification shall require the written consent of the Executive.  In no event whatsoever shall the Company be liable for any additional tax, interest or penalty that may be imposed on the Executive by Code Section 409A or damages for failing to comply with Code Section 409A; provided that the Company makes any modification reasonably requested by the Executive in accordance with the second sentence of this Section 24(b)(i).

(ii)A termination of employment shall not be deemed to have occurred for purposes of any provision of this Agreement providing for the payment of any amounts or benefits upon or following a termination of employment unless such termination is also a “separation from service” within the meaning of Code Section 409A and, for purposes of any such provision of this Agreement, references to a “termination,” “termination of employment” or like terms shall mean “separation from service.”  If the Executive is deemed on the date of termination to be a “specified employee” within the meaning of that term under Code Section 409A(a)(2)(B), then with regard to any payment or the provision of any benefit that is considered “nonqualified deferred compensation” under Code Section 409A payable on account of a “separation from service,” such payment or benefit shall be made or provided at the date which is the earlier of (A) the expiration

15

of the six (6)-month period measured from the date of such “separation from service” of the Executive, and (B) the date of the Executive’s death, to the extent required under Code Section 409A.  Upon the expiration of the foregoing delay period, all payments and benefits delayed pursuant to this Section 24(b)(ii) (whether they would have otherwise been payable in a single sum or in installments in the absence of such delay) shall be paid or reimbursed to the Executive in a lump sum and all remaining payments and benefits due under this Agreement shall be paid or provided in accordance with the normal payment dates specified for them herein.

(iii)To the extent that reimbursements or other in-kind benefits under this Agreement constitute “nonqualified deferred compensation” for purposes of Code Section 409A, (A) all expenses or other reimbursements hereunder shall be made on or prior to the last day of the taxable year following the taxable year in which such expenses were incurred by the Executive, (B) any right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit, and (C) no such reimbursement, expenses eligible for reimbursement, or in-kind benefits provided in any taxable year shall in any way affect the expenses eligible for reimbursement, or in-kind benefits to be provided, in any other taxable year.

(iv)For purposes of Code Section 409A, the Executive’s right to receive installment payments pursuant to this Agreement shall be treated as a right to receive a series of separate and distinct payments.  Whenever a payment under this Agreement specifies a payment period with reference to a number of days, the actual date of payment within the specified period shall be within the sole discretion of the Company.

25.FURTHER ASSURANCES; PARENT GUARANTEE.  The parties hereto shall cooperate with each other and do, or procure the doing of, all acts and things, and execute, or procure the execution of, all documents, as may reasonably be required to give full effect to this Agreement.  Parent hereby guarantees the performance of the obligations of the Company to pay all cash amounts due to the Executive pursuant to this Agreement.  In the event that the Company is unable or unwilling to pay any such amounts when due, upon notice of such non-payment received by Parent from the Executive, Parent shall immediately pay such amounts, or take any and all actions necessary to cause one or more Affiliates to pay such amounts, on behalf of the Company.

EXHIBIT A

GENERAL RELEASE

I, Angelo Chaclas, in consideration of and subject to the performance by Bain Capital Everest US Holding, Inc. (together with its subsidiaries, the “Company”), of its obligations under the Employment Agreement, dated as of November ____, 2014 (the “Agreement”), do hereby release and forever discharge as of the date hereof the Company and its respective “Affiliates” (as defined in the Agreement) and all present, former and future directors, officers, employees, successors and assigns of the Company and its Affiliates and direct or indirect owners (collectively, the “Released Parties”) to the extent provided below. The Released Parties are intended third-party beneficiaries of this General Release, and this General Release may be enforced by each of them in accordance with the terms hereof in respect of the rights granted to such Released Parties hereunder.  Terms used herein but not otherwise defined shall have the meanings given to them in the Agreement.

1.I understand that any payments or benefits paid or granted to me under Section 7 of the Agreement represent, in part, consideration for signing this General Release and are not salary, wages or benefits to which I was already entitled. I understand and agree that I will not receive certain of the payments and benefits specified in Section 7 of the Agreement unless I execute this General Release and do not revoke this General Release within the time period permitted hereafter.  Such payments and benefits will not be considered compensation for purposes of any employee benefit plan, program, policy or arrangement maintained or hereafter established by the Company or its affiliates.

2.Except as provided in paragraphs 4 and 5 below and except for the provisions of the Agreement which expressly survive the termination of my employment with the Company, I knowingly and voluntarily (for myself, my heirs, executors, administrators and assigns) release and forever discharge the Company and the other Released Parties from any and all claims, suits, controversies, actions, causes of action, cross-claims, counter‑claims, demands, debts, compensatory damages, liquidated damages, punitive or exemplary damages, other damages, claims for costs and attorneys’ fees, or liabilities of any nature whatsoever in law and in equity, both past and present (through the date this General Release becomes effective and enforceable) and whether known or unknown, suspected, or claimed against the Company or any of the Released Parties which I, my spouse, or any of my heirs, executors, administrators or assigns, may have, which arise out of or are connected with my employment with, or my separation or termination from, the Company (including, but not limited to, any allegation, claim or violation, arising under:  Title VII of the Civil Rights Act of 1964, as amended; the Civil Rights Act of 1991; the Age Discrimination in Employment Act of 1967, as amended (including the Older Workers Benefit Protection Act); the Equal Pay Act of 1963, as amended; the Americans with Disabilities Act of 1990; the Family and Medical Leave Act of 1993; the Worker Adjustment Retraining and Notification Act; the Employee Retirement Income Security Act of 1974; any applicable Executive Order Programs; the Fair Labor Standards Act; or their state or local counterparts; or under any other federal, state or local civil or human rights law, or under any other local, state, or federal law, regulation or ordinance; or under any public policy, contract or tort, or under common law; or arising under any policies, practices or procedures of the Company; or any claim for wrongful discharge, breach of contract, infliction of emotional distress, defamation; or any claim for costs,

A-1

fees, or other expenses, including attorneys’ fees incurred in these matters) (all of the foregoing collectively referred to herein as the “Claims”).

3.I represent that I have made no assignment or transfer of any right, claim, demand, cause of action, or other matter covered by paragraph 2 above.

4.I agree that this General Release does not waive or release any rights or claims that I may have which arise after the date I execute this General Release, including, without limitation, Claims under the Age Discrimination in Employment Act of 1967. I acknowledge and agree that my separation from employment with the Company in compliance with the terms of the Agreement shall not serve as the basis for any claim or action (including, without limitation, any claim under the Age Discrimination in Employment Act of 1967).

5.I agree that I hereby waive all rights to sue or obtain equitable, remedial or punitive relief from any or all Released Parties of any kind whatsoever in respect of any Claim, including, without limitation, reinstatement, back pay, front pay, and any form of injunctive relief.  Notwithstanding the above, I further acknowledge that I am not waiving and am not being required to waive any right that cannot be waived under law, including the right to file an administrative charge or participate in an administrative investigation or proceeding; provided, however, that I disclaim and waive any right to share or participate in any monetary award resulting from the prosecution of such charge or investigation or proceeding.  Additionally, I am not waiving any right to the Accrued Benefits or claims for indemnity or contribution.

6.In signing this General Release, I acknowledge and intend that it shall be effective as a bar to each and every one of the Claims hereinabove mentioned or implied. I expressly consent that this General Release shall be given full force and effect according to each and all of its express terms and provisions, including those relating to unknown and unsuspected Claims (notwithstanding any state or local statute that expressly limits the effectiveness of a general release of unknown, unsuspected and unanticipated Claims), if any, as well as those relating to any other Claims hereinabove mentioned or implied.  I acknowledge and agree that this waiver is an essential and material term of this General Release and that without such waiver the Company would not have agreed to the terms of the Agreement.  I further agree that in the event I should bring a Claim seeking damages against the Company, or in the event I should seek to recover against the Company in any Claim brought by a governmental agency on my behalf, this General Release shall serve as a complete defense to such Claims to the maximum extent permitted by law.  I further agree that I am not aware of any pending claim of the type described in paragraph 2 as of the execution of this General Release.

7.I agree that neither this General Release, nor the furnishing of the consideration for this General Release, shall be deemed or construed at any time to be an admission by the Company, any Released Party or myself of any improper or unlawful conduct.

8.I agree that if I violate this General Release by suing the Company or the other Released Parties, I will pay all costs and expenses of defending against the suit incurred by the Released Parties, including reasonable attorneys’ fees.

(f)REASONABLENESS OF COVENANTS.In signing this Agreement, the Executive gives the Company assurance that the Executive has carefully read and considered all of the terms and conditions of this Agreement, including the restraints imposed under this Section 11.The Executive agrees that these restraints are necessary for the reasonable and proper protection of the Company and its Affiliates and their trade secrets and confidential information and that each and every one of the restraints is reasonable in respect to subject matter, length of time and geographic area, and that these restraints, individually or in the aggregate, will not prevent the Executive from obtaining other suitable employment during the period in which the Executive is bound by the restraints.The Executive acknowledges that each of these covenants has a unique, very substantial and immeasurable value to the Company and its Affiliates and that the Executive has sufficient assets and skills to provide a livelihood while such covenants remain in force. It is also agreed that the Affiliates will have the right to enforce all of the Executive’s obligations to such Affiliates under this Agreement, including without limitation pursuant to this Section 11.

(g)REFORMATION.If it is determined by a court of competent jurisdiction in any state that any restriction in this Section 11 is excessive in duration or scope or is unreasonable or unenforceable under applicable law, it is the intention of the parties that such restriction may be

8

modified or amended by the court to render it enforceable to the maximum extent permitted by the laws of that state.

(h)SURVIVAL OF PROVISIONS.The obligations contained in Sections 11 and 12 hereof shall survive the termination or expiration of the Employment Term and the Executive’s employment with the Company and shall be fully enforceable thereafter.

12.COOPERATION.Upon the receipt of reasonable notice from the Company (including through outside counsel), the Executive agrees that while employed by the Company and thereafter (to the extent it does not materially interfere with the Executive’s employment or other business activities after employment by the Company), the Executive will respond and provide information with regard to matters in which the Executive has knowledge as a result of the Executive’s employment with the Company, and will provide reasonable assistance to the Company, the Affiliates and their respective representatives in defense of all claims that may be made against the Company or theAffiliates, and will assist the Company and theAffiliates in the prosecution of all claims that may be made by the Company or the Affiliates, to the extent that such claims may relate to the period of the Executive’s employment with the Company.The Executive also agrees to promptly inform the Company (to the extent that the Executive is legally permitted to do so) if the Executive is asked to assist in any investigation of the Company or the Affiliates (or their actions), regardless of whether a lawsuit or other proceeding has then been filed against the Company or Affiliates with respect to such investigation, and shall not do so unless legally required.Upon presentation of appropriate documentation, the Company shall pay or reimburse the Executive for all reasonable out-of-pocket travel, duplicating, telephonic, counsel and other expenses incurred by the Executive in complying with this Section 12.

13.EQUITABLE RELIEF AND OTHER REMEDIES.The Executive acknowledges and agrees that the Company’s remedies at law for a breach or threatened breach of any of the provisions of Section 11 hereof or Section 12 hereof would be inadequate and, in recognition of this fact, the Executive agrees that, in the event of such a breach or threatened breach, in addition to any remedies at law, the Company shall be entitled to obtain equitable relief in the form of specific performance  (Realerfüllung), a temporary restraining order, a temporary or permanent injunction or any other equitable remedy which may then be available.In the event of a Material Covenant Violation or a Material Cooperation Violation by the Executive, any severance being paid to the Executive pursuant to this Agreement or otherwise shall immediately cease unless otherwise prohibited by applicable law. In case of a breach by the Executive of any of the covenants contained in Section 11 or Section 12 hereof (i) any Severance Amount payable by the Company, if any, shall be forfeited and (ii) the Executive shall pay to the Company liquidated damages in an amount equal the Executive's prior annual Base Salary for each individual breach of the aforementioned provisions. In addition, the Executive shall have to compensate the Company for any further damages and financial losses directly arising out of or relating to such breach. The Executive cannot disburden himself from the aforementioned prohibitions by the payment of the liquidated damages and/or further damages.

14.NO ASSIGNMENTS.This Agreement is personal to each of the parties hereto.Except as provided in this Section 14 hereof, no party may assign or delegate any rights or obligations hereunder without first obtaining the written consent of the other party hereto.The Company shall assign this Agreement to any successor to all or substantially all of the business and/or assets

9

of the Company or Parent,  provided that the Company shall require such successor to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place, and provided that the Company agrees to perform such obligations if such successor fails to do so in a timely manner.As used in this Agreement, “Company” shall mean the Company and any successor to all or substantially all of its business and/or assets, which assumes and agrees to perform the duties and obligations of the Company under this Agreement by operation of law or otherwise.

I, Hayati Yarkadas,in consideration of and subject to the performance by Trinseo Europe GmbH.(together with its subsidiaries, the “Company”), of its obligations under the Employment Agreement, dated as of [●], 2015 (the “Agreement”), do hereby release and forever discharge as of the date hereof the Company and its respective Affiliates and all present, former and future directors, officers, employees, successors and assigns of the Company and its Affiliates and direct or indirect owners (collectively, the “Released Parties”) to the extent provided below. The Released Parties are intended third-party beneficiaries of this General Release, and this General Release may be enforced by each of them in accordance with the terms hereof in respect of the rights granted to such Released Parties hereunder.Terms used herein but not otherwise defined shall have the meanings given to them in the Agreement.

1.I understand that any payments or benefits paid or granted to me under Section 8 of the Agreement represent, in part, consideration for signing this General Release and are not salary, wages or benefits to which I was already entitled. I understand and agree that I will not receive certain of the payments and benefits specified in Section 8 of the Agreement unless I execute this General Release and do not revoke this General Release within the time period permitted hereafter.Such payments and benefits will not be considered compensation for purposes of any employee benefit plan, program, policy or arrangement maintained or hereafter established by the Company or its affiliates.

2.Except as provided in paragraphs1 aboveand 5below and except for the provisions of the Agreement which expressly survive the termination of my employment with the Company, I knowingly and voluntarily (for myself, my heirs, executors, administrators and assigns) release and forever discharge the Company and the other Released Parties from any and all claims, suits, controversies, actions, causes of action, cross-claims, counter‑claims, demands, debts, compensatory damages, liquidated damages, punitive or exemplary damages, other damages, claims for costs and attorneys’ fees, or liabilities of any nature whatsoever in law and in equity, both past and present (through the date this General Release becomes effective and enforceable) and whether known or unknown, suspected, or claimed against the Company or any of the Released Parties which I, my spouse, or any of my heirs, executors, administrators or assigns, may have, which arise out of or are connected with my employment with, or my separation or termination from, the Company (all of the foregoing collectively referred to herein as the “Claims”).

3.I represent that I have made no assignment or transfer of any right, claim, demand, cause of action, or other matter covered by paragraph 2 above.

4.I agree that this General Release does not waive or release any rights or claims that I may have which arise after the date I execute this General Release.

13.Notwithstanding anything in this General Release to the contrary, this General Release shall not relinquish, diminish, or in any way affect any rights or claims arising out of any breach by the Company or by any Released Party of the Agreement after the date hereof.

Organization and Business Activities

NOTE 1—ORGANIZATION AND BUSINESS ACTIVITIES

Organization

On June 3, 2010, Bain Capital Everest Manager Holding SCA (the “Parent”), an affiliate of Bain Capital Partners, LP (“Bain Capital”), was formed through investment funds advised or managed by Bain Capital. Dow Europe Holding B.V. (together with The Dow Chemical Company, “Dow”) retained an indirect ownership interest in the Parent. Trinseo S.A. (“Trinseo”, and together with its subsidiaries, the “Company”) was also formed on June 3, 2010, incorporated under the existing laws of the Grand Duchy of Luxembourg. At that time, all ordinary shares of Trinseo were owned by the Parent. On June 17, 2010, Trinseo acquired 100% of the former Styron business from Dow (the “Acquisition”), at which time, the Company commenced operations.

On May 30, 2014, the Company amended its Articles of Association to effect a 1-for-436.69219 reverse split of its issued and outstanding ordinary shares (“reverse split”) and to increase its authorized shares to 50.0 billion. All share and per share data were retroactively adjusted in the accompanying financial statements to give effect to the reverse split.

On June 17, 2014, Trinseo completed an initial public offering (the “IPO”) of 11,500,000 ordinary shares at a price of $19.00 per share, which included 1,500,000 shares sold pursuant to the underwriters’ exercise of their over-allotment option. The Company received cash proceeds of $203.2 million from this transaction, net of underwriting discounts. See Note 12 for more information.

NOTE 2—BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation and Principles of Consolidation

The accompanying consolidated financial statements as of December 31, 2015 and 2014 and for each of the three years in the period ended December 31, 2015 are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The consolidated financial statements of the Company contain the accounts of all entities that are controlled and variable interest entities (“VIEs”) for which the Company is the primary beneficiary. A VIE is defined as a legal entity that has equity investors that do not have sufficient equity at risk for the entity to support its activities without additional subordinated financial support or, as a group, the holders of the equity at risk lack (i) the power to direct the entity’s activities or (ii) the obligation to absorb the expected losses or the right to receive the expected residual returns of the entity. A VIE is required to be consolidated by a company if that company is the primary beneficiary. Refer to Note 10 for further discussion of the Company’s accounts receivable securitization facility, which qualifies as a VIE and is consolidated within the Company’s financial statements.

All intercompany balances and transactions are eliminated. Joint ventures over which the Company has the ability to exercise significant influence that are not consolidated are accounted for by the equity method.

Use of Estimates in Financial Statement Preparation

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual amounts could differ from these estimates.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash equivalents and accounts receivables. The Company uses major financial institutions with high credit ratings to engage in transactions involving cash equivalents. The Company minimizes credit risk in its receivables by selling products to a diversified portfolio of customers in a variety of markets located throughout the world.

The Company performs ongoing evaluations of its customers’ credit and generally does not require collateral. The Company maintains an allowance for doubtful accounts for losses resulting from the inability of specific customers to meet their financial obligations, representing our best estimate of probable credit losses in existing trade accounts receivable. A specific reserve for doubtful receivables is recorded against the amount due from these customers. For all other customers, the Company recognizes reserves for doubtful receivables based on historical experience.

Financial Instruments

The carrying amounts of the Company’s financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and accrued and other current liabilities, approximate fair value due to their generally short maturities.

The estimated fair value of the Company’s 2021 Term Loan B, 2022 Senior Notes, and 2019 Senior Notes (all of which are defined in Note 10) are determined using level 2 inputs within the fair value hierarchy. Refer to Note 13 for the fair value of these debt instruments. When outstanding, the estimated fair values of borrowings under the Company’s 2020 Revolving Facility and Accounts Receivable Securitization Facility (both of which are defined in Note 10) are determined using level 2 inputs within the fair value hierarchy. The carrying amounts of borrowings under the 2020 Revolving Facility and Accounts Receivable Securitization Facility approximate fair value as these borrowings bear interest based on prevailing variable market rates.

At times, the Company manages its exposure to changes in foreign currency exchange rates, where possible, by entering into foreign exchange forward contracts. When outstanding, all derivatives, whether designated in hedging relationships or not, are required to be recorded on the balance sheet at fair value. The fair value of the derivatives is determined from sources independent of the Company, including the financial institutions which are party to the derivative instruments. The fair value of derivatives also considers the credit default risk of the paying party. If the derivative is designated as a fair value hedge, the changes in the fair value of the derivative and the hedged item will be recognized in earnings. If the derivative is designated as a cash flow hedge, the effective portion of the change in the fair value of the derivative will be recorded in other comprehensive income and will be recognized in the consolidated statements of operations when the hedged item affects earnings.

As of December 31, 2015 and 2014, the Company had certain foreign exchange forward contracts outstanding that were not designated for hedge accounting treatment. As such, the settlements and changes in fair value of underlying instruments are recognized in “Other expense, net” in the consolidated statements of operations. For the years ended December 31, 2015, 2014, and 2013, the Company recognized losses related to these forward contracts of $16.5 million, $28.2 million, and $0.6 million, respectively.

As of December 31, 2015, the Company also had foreign exchange forward contracts which are designated as cash flow hedges. As such, 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 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. No such contracts were outstanding as of December 31, 2014.

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. The Company records these foreign exchange forward contracts on a net basis, by counterparty within the consolidated balance sheets.

The Company presents the cash receipts and payments from hedging activities in the same category as the cash flows from the items subject to hedging relationships. As the items subject to economic hedging relationships are the Company’s operating assets and liabilities, the related cash flows are classified within operating activities in the consolidated statements of cash flows.

Foreign Currency Translation

For the majority of the Company’s subsidiaries, the local currency has been identified as the functional currency. For remaining subsidiaries, the U.S. dollar has been identified as the functional currency due to the significant influence of the U.S. dollar on their operations. Gains and losses resulting from the translation of various functional currencies into U.S. dollars are not recorded within the consolidated statements of operations. Rather, they are recorded within the cumulative translation adjustment account as a separate component of shareholders’ equity (accumulated other comprehensive income) on the consolidated balance sheets. The Company translates asset and liability balances at exchange rates in effect at the end of the period and income and expense transactions at the average exchange rates in effect during the period. Gains and losses resulting from foreign currency transactions are recorded within the consolidated statements of operations.

For the year ended December 31, 2015 and 2014, the Company recognized net foreign exchange transaction gains of $6.1 million and $32.4 million, respectively. For the year ended December 31, 2013, the Company recognized net foreign exchange transaction losses of $18.3 million. These amounts exclude the impacts of foreign exchange forward contracts discussed above. Gains and losses on net foreign exchange transactions are recorded within “Other expense, net” in the consolidated statements of operations.

Environmental Matters

Accruals for environmental matters are recorded when it is considered probable that a liability has been incurred and the amount of the liability can be reasonably estimated, based on current law and existing technologies. These accruals are adjusted periodically as assessment and remediation efforts progress, or as additional technical or legal information become available. Accruals for environmental liabilities are recorded within “Other noncurrent obligations” in the consolidated balance sheets at undiscounted amounts. As of December 31, 2015 and 2014, there were no accruals for environmental liabilities recorded.

Environmental costs are capitalized if the costs extend the life of the property, increase its capacity, or mitigate or prevent contamination from future operations. Environmental costs are also capitalized in recognition of legal asset retirement obligations resulting from the acquisition, construction or normal operation of a long-lived asset. Any costs related to environmental contamination treatment and clean-ups are charged to expense. Estimated future incremental operations, maintenance and management costs directly related to remediation are accrued when such costs are probable and reasonably estimable.

Cash and Cash Equivalents

Cash and cash equivalents generally include time deposits or highly liquid investments with original maturities of three months or less.

Inventories

Inventories are stated at the lower of cost or market, with cost being determined on the first-in, first-out (“FIFO”) method. The Company periodically reviews its inventory for excess or obsolete inventory, and will write-down the excess or obsolete inventory value to its net realizable value, if applicable.

Property, Plant and Equipment

Property, plant and equipment are carried at cost less accumulated depreciation and less impairment, if applicable, and are depreciated over their estimated useful lives using the straight-line method. Capitalized costs associated with computer software for internal use are amortized on a straight-line basis over their estimated useful life.

Expenditures for maintenance and repairs are charged against income as incurred. Expenditures that significantly increase asset value, extend useful asset lives or adapt property to a new or different use are capitalized. These expenditures include planned major maintenance activity or turnaround activities that increase our manufacturing plants’ output and improve production efficiency as compared to pre-turnaround operations. As of December 31, 2015 and 2014, $7.6 million and $9.2 million, respectively, of the Company’s net costs related to turnaround activities were capitalized within “Deferred charges and other assets” in the consolidated balance sheets, and are being amortized over the period until the next scheduled turnaround.

The Company periodically evaluates actual experience to determine whether events and circumstances have occurred that may warrant revision of the estimated useful lives of property, plant and equipment. Engineering and other costs directly related to the construction of property, plant and equipment are capitalized as construction in progress until construction is complete and such property, plant and equipment is ready and available to perform its specifically assigned function. Upon retirement or other disposal, the asset cost and related accumulated depreciation are removed from the accounts and the net amount, less any proceeds, is charged or credited to income. The Company also capitalizes interest as a component of the cost of capital assets constructed for its own use.

Impairment and Disposal of Long-Lived Assets

The Company evaluates long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. When undiscounted future cash flows are not expected to be sufficient to recover an asset’s carrying amount, the asset is written down to its fair value based on a discounted cash flow analysis utilizing market participant assumptions.

Long-lived assets to be disposed of by sale are classified as held-for-sale and are reported at the lower of carrying amount or fair value less cost to sell, and depreciation is ceased. Long-lived assets to be disposed of in a manner other than by sale are classified as held-and-used until they are disposed.

Goodwill and Other Intangible Assets

The Company records goodwill when the purchase price of a business acquisition exceeds the estimated fair value of net identified tangible and intangible assets acquired. Goodwill is tested for impairment at the reporting unit level annually, or more frequently when events or changes in circumstances indicate that the fair value of a reporting unit has more likely than not declined below its carrying value. The Company utilizes a market approach and an income approach (under the discounted cash flow method) to calculate the fair value of its reporting units. The annual impairment assessment is completed using a measurement date of October 1st.  No goodwill impairment losses were recorded in the years ended December 31, 2015, 2014 and 2013.

Finite-lived intangible assets, such as our intellectual property and manufacturing capacity rights, are amortized on a straight-line basis and are reviewed for impairment or obsolescence if events or changes in circumstances indicate that their carrying amount may not be recoverable. If impaired, intangible assets are written down to fair value based on discounted cash flows. No intangible asset impairment losses were recorded in the years ended December 31, 2015, 2014 and 2013.

Deferred Financing Fees

Capitalized fees and costs incurred in connection with the Company’s financing arrangements are recorded in “Deferred charges and other assets” within the consolidated balance sheets. For the 2021 Term Loan B and 2022 Senior Notes (and the 2019 Senior Notes, prior to their repayment in May 2015), deferred financing fees are amortized over the term of the agreement using the effective interest method, while for the 2020 Revolving Facility and the Accounts Receivable Securitization Facility, deferred financing fees are amortized using the straight-line method over the term of the respective facility. Amortization of deferred financing fees is recorded in “Interest expense, net” within the consolidated statements of operations.

Investments in Unconsolidated Affiliates

Investments in unconsolidated affiliates in which the Company has the ability to exercise significant influence (generally, 20% to 50% owned companies) are accounted for using the equity method. Investments are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount of the investment may not be recoverable. An impairment loss is recorded whenever a decline in fair value of an investment in an unconsolidated affiliate below its carrying amount is determined to be other-than-temporary.

Sales

Sales are recognized when the revenue is realized or realizable and the earnings process is complete, which occurs when risk and title to the product transfers to the customer, typically at the time shipment is made. As such, title to the product generally passes when the product is delivered to the freight carrier. Standard terms of delivery are included in contracts of sale, order confirmation documents and invoices. Freight costs and any directly related costs of transporting finished product to customers are recorded as “Cost of sales” in the consolidated statements of operations. Taxes on sales are excluded from net sales.

Sales are recorded net of estimates for returns and price allowances, including discounts for prompt payment and volume-based incentives.

Cost of Sales

The Company classifies the costs of manufacturing and distributing its products as cost of sales. Manufacturing costs include raw materials, utilities, packaging and fixed manufacturing costs associated with production. Fixed manufacturing costs include such items as plant site operating costs and overhead, production planning, depreciation and amortization, repairs and maintenance, environmental, and engineering costs. Distribution costs include shipping and handling costs.

Selling, General and Administrative Expenses

Selling, general and administrative (“SG&A”) expenses are charged to expense as incurred. SG&A expenses are the cost of services performed by the marketing and sales functions (including sales managers, field sellers, marketing research, marketing communications and promotion and advertising materials) and by administrative functions (including product management, R&D, business management, customer invoicing, and human resources). R&D expenses include the cost of services performed by the R&D function, including technical service and development, process research including pilot plant operations, and product development.

Total R&D costs included in SG&A expenses were approximately $51.9 million, $53.4 million and $49.7 million for the years ended December 31, 2015, 2014 and 2013, respectively.

The Company expenses promotional and advertising costs as incurred to SG&A expenses. Total promotional and advertising expenses were approximately $3.5 million, $2.9 million and $3.0 million for the years ended December 31, 2015, 2014 and 2013, respectively.

Pension and Postretirement Benefits Plans

The Company has several defined benefit plans, under which participants earn a retirement benefit based upon a formula set forth in the plan. The Company also provides certain health care and life insurance benefits to retired employees mainly in the United States and Brazil. The plans provide health care benefits, including hospital, physicians’ services, drug and major medical expense coverage, and life insurance benefits.

Accounting for defined benefit pension plans and other postretirement benefit plans, and any curtailments and settlements thereof, requires various assumptions, including, but not limited to, discount rates, expected rates of return on plan assets and future compensation growth rates. The Company evaluates these assumptions at least once each year, or as facts and circumstances dictate, and makes changes as conditions warrant.

A settlement is a transaction that is an irrevocable action that relieves the employer (or the plan) of primary responsibility for a pension or postretirement benefit obligation, and that eliminates significant risks related to the obligation and the assets used to effect the settlement. When a settlement occurs, the Company does not record settlement gains or losses during interim periods when the cost of all settlements in a year is less than or equal to the sum of the service cost and interest cost components of net periodic pension cost for the plan in that year.

Income Taxes

The provision for income taxes is determined using the asset and liability approach of accounting for income taxes. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from differences between the financial and tax basis of the Company’s assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. With the adoption of new guidance from the Financial Accounting Standards Board (“FASB”) as of December 31, 2015, for each tax jurisdiction in which the Company operates, deferred tax assets and liabilities are offset against one another and are presented as a single noncurrent amount within the consolidated balance sheets.  See “- Recent Accounting Guidance” below for further discussion of the impact of adopting this guidance.

Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. Provision has been made for income taxes on unremitted earnings of subsidiaries and affiliates, except for subsidiaries in which earnings are deemed to be indefinitely invested.

The Company recognizes the financial statement effects of uncertain income tax positions when it is more likely than not, based on the technical merits, that the position will be sustained upon examination. The Company accrues for other tax contingencies when it is probable that a liability to a taxing authority has been incurred and the amount of the contingency can be reasonably estimated. Interest accrued related to unrecognized tax and income tax related penalties are included in the provision for income taxes. The current portion of uncertain income taxes positions is recorded in “Income taxes payable” while the long-term portion is recorded in “Other noncurrent obligations” in the consolidated balance sheets.

Stock-based Compensation

Refer to Note 17 to the consolidated financial statements for detailed discussion regarding the Company’s stock-based compensation award programs.  The following provides a brief summary of the key accounting policy elections related to these awards.

On all awards, forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Stock-based compensation expense recognized in our consolidated financial statements is based on awards that are ultimately expected to vest.

Restricted Stock Awards issued by the Parent

From 2010 through 2013, our Parent granted various time-based and performance-based restricted stock awards to certain key members of management. Any related compensation associated with these awards is allocated to the Company from the Parent.

Stock-based compensation expense for these awards is measured at the grant date, based on the fair value of the award. Time-based and modified time-based restricted stock awards are generally recognized as expense on a graded vesting basis over the related service period. Prior to their modification in June 2014, the Company recognized compensation cost related to performance-based restricted stock awards if and when it was deemed probable that the related performance condition would be achieved. When applicable, the Company calculated the fair value of its performance-based restricted stock awards using a combination of a call option and digital option model.

2014 Omnibus Incentive Plan

In connection with the IPO, the Company’s board of directors approved the 2014 Omnibus Plan. Since that time, certain equity grants have been awarded, comprised of RSUs and options awards (defined in Note 17 to the consolidated financial statements).

Compensation costs for the RSUs are measured at the grant date based on the fair value of the award and are recognized ratably as expense over the applicable vesting term. The fair value of RSUs is equal to the fair market value of the Company’s ordinary shares based on the closing price on the date of grant.

Compensation cost for the option awards is measured at the grant date based on the fair value of the award and is recognized as expense over the appropriate service period utilizing graded vesting. The fair value for option awards is computed using the Black-Scholes pricing model, whose inputs and assumptions are determined as of the date of grant.

Recent Accounting Guidance

In April 2014, the FASB issued amendments to guidance for reporting discontinued operations and disposals of components of an entity. The amended guidance requires that a disposal representing a strategic shift that has (or will have) a major effect on an entity’s financial results or a business activity classified as held-for-sale should be reported as discontinued operations. The amendments also expand the disclosure requirements for discontinued operations and add new disclosures for individually significant dispositions that do not qualify as discontinued operations. The Company adopted this guidance effective January 1, 2015, and the adoption did not have a significant impact on the Company’s financial position, results of operations, or disclosures.

In May 2014, the FASB and the International Accounting Standards Board (“IASB”) jointly issued new 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. This guidance is effective for public entities for annual and interim periods beginning after December 15, 2017. The Company is currently assessing the impact of adopting this guidance on its financial statements and results of operations.

In January 2015, the FASB issued guidance to simplify income statement classification by removing the concept of extraordinary items from GAAP. The Company adopted this guidance effective January 1, 2015 and the adoption did not have an impact on the Company’s financial position or results of operations.

In April 2015, the FASB issued guidance that requires deferred financing fees related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying value of that debt liability, consistent with debt discounts. The recognition and measurement guidance for deferred financing fees are not affected. This new guidance, which is to be applied on a retrospective basis, is effective for public companies for annual and interim periods beginning after December 15, 2015, with early adoption permitted. The Company will adopt this guidance effective January 1, 2016.  As of December 31, 2015, the Company had $32.7 million of unamortized deferred financing fees classified as noncurrent assets within “Deferred charges and other assets” on the consolidated balance sheet, of which approximately $25.7 million will be reclassified as a reduction of “Long-term debt” on the consolidated balance sheet upon adoption.

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. This pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2016, and prospective adoption is required. The Company is currently assessing the impact of adopting this guidance on its financial position and results of operations.

In November 2015, the FASB issued guidance which requires that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. This guidance is effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods, and may be applied either prospectively or retrospectively, with early adoption permitted. The Company adopted this guidance effective December 31, 2015 on a prospective basis, noting that prior periods were not retrospectively adjusted. If the Company had retrospectively adopted this guidance, $11.8 million and $1.4 million of current deferred tax assets and liabilities, respectively, would have been reclassified, resulting in a total of $57.1 million and $27.2 million of noncurrent deferred tax assets and liabilities, respectively, on the consolidated balance sheet as of December 31, 2014.

Acquisitions and Divestitures

NOTE 3—ACQUISITIONS AND DIVESTITURES

The Acquisition

The Company accounted for the Acquisition (as discussed in Note 1) under the purchase method of accounting, whereby the purchase price paid, net of working capital adjustments, was allocated to the acquired assets and liabilities at fair value. As of June 17, 2011, the one-year measurement period surrounding the Acquisition ended. During 2014, an adjustment was identified related to one of our postretirement benefit plans, which dated back to the initial Acquisition accounting. As such, the Company recorded a $1.7 million increase to goodwill to correct our final purchase price allocation, with the offset recorded to postretirement benefit liabilities. The Company does not believe this adjustment was material to our prior period financial statements. Refer to Note 16 for further discussion.

As part of the Acquisition, the Company has been indemnified for various tax matters, including income tax and value add taxes, as well as legal liabilities which have been incurred prior to the Acquisition. Conversely, certain tax matters which the Company has benefitted from are subject to reimbursement by Trinseo to Dow. These amounts have been estimated and provisional amounts have been recorded based on the information known during the measurement period; however, these amounts remain subject to change based on the completion of our annual statutory filings, tax authority review as well as a final resolution with Dow on amounts due to and due from the Company. Management believes the Company’s estimates and assumptions are reasonable under the circumstances, however, settlement negotiations or changes in estimates around pre-acquisition indemnifications could result in a material impact on the consolidated financial statements.

During 2013, the Company received $6.7 million, net of tax indemnity from Dow for income taxes paid to the taxing authorities relating to the period prior to the Acquisition. This indemnity amount was previously recorded within “Accounts receivable, net of allowance” in the consolidated balance sheets. There were no other significant indemnity payments received from Dow or indemnity payments to Dow during the years ended December 31, 2015, 2014, and 2013, respectively.

Divestiture of Expandable Polystyrene Business

In June 2013, the Company’s board of directors approved the sale of its expandable polystyrene (“EPS”) business within the Company’s Basic Plastics & Feedstocks segment, under a sale and purchase agreement which was signed in July 2013. The sale closed on September 30, 2013 and the Company received $15.2 million of sales proceeds during the third quarter of 2013, subject to a $0.7 million working capital adjustment which was paid by the Company during the first quarter of 2014 and is reflected within investing activities in the consolidated statement of cash flows for the year ended December 31, 2014. The Company recognized a loss from the sale of $4.2 million recorded in “Other expense, net” in the consolidated statement of operations for the year ended December 31, 2013. The loss calculation is as follows:

Assets
Inventories	$	8,135
Property, plant and equipment, net		9,401
Other intangibles assets, net		1,624
Goodwill		383
Total assets sold	$	19,543
Liabilities
Pension and other benefits	$	791
Total liabilities sold	$	791
Net assets sold	$	18,752
Sales proceeds, net of amount paid to buyer of $0.7 million		14,566
Loss on sale	$	4,186

EPS business results of operations were not classified as discontinued operations as the Company will have significant continuing cash flows as a result of a long-term supply agreement of styrene monomer to the EPS business, which was entered into contemporaneously with the sale and purchase agreement.

Further, under the terms of the sale and purchase agreement, should the divested EPS business record EBITDA (as defined therein) greater than zero for fiscal year 2014, the Company would receive an incremental payment of €0.5 million. The EBITDA threshold was met for fiscal year 2014, and the Company recorded the contingent gain on sale of €0.5 million (approximately $0.6 million) related to this incremental payment for the year ended December 31, 2014. The payment was received during the first quarter of 2015 and is reflected within cash flows used in investing activities in the consolidated statement of cash flows for the year ended December 31, 2015.

Livorno Land Sale

In April 2014, the Company completed the sale of a portion of land at its manufacturing site in Livorno, Italy for a purchase price of €4.95 million (approximately $6.8 million). As a result, the Company recorded a gain on sale of $0.1 million within “Other expense, net” in the consolidated statements of operations for the year ended December 31, 2014.

NOTE 4—INVESTMENTS IN UNCONSOLIDATED AFFILIATES

The Company is supplemented by two strategic joint ventures, the results of which are included within the Basic Plastics & Feedstocks reporting segment: Americas Styrenics (a polystyrene joint venture with Chevron Phillips Chemical Company LP) and Sumika Styron Polycarbonate (a polycarbonate joint venture with Sumitomo Chemical Company Limited).

As of December 31, 2015 and 2014, respectively, the Company’s investment in Americas Styrenics was $143.9 million and $133.5 million, which was $91.9 million and $108.4 million less than the Company’s 50% share of Americas Styrenics’ underlying net assets. These amounts represent 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 4.8 years as of December 31, 2015. The Company received dividends from Americas Styrenics of $125.0 million, $35.0 million, and $22.5 million for the years ended December 31, 2015, 2014, and 2013, respectively.

As of December 31, 2015 and 2014, respectively, the Company’s investment in Sumika Styron Polycarbonate was $39.0 million and $34.1 million, which was $19.8 million and $21.3 million greater than the Company’s 50% share of Sumika Styron Polycarbonate’s underlying net assets. These amounts represent the fair value of certain identifiable assets which have not been recorded on the historical financial statements of Sumika Styron Polycarbonate. This difference is being amortized over the remaining useful life of the contributed assets of 9.8 years as of December 31, 2015. The Company received no dividends from Sumika Styron Polycarbonate for the year ended December 31, 2015, and received dividends of $1.0 million and $1.1 million for the years ended December 31, 2014 and 2013, respectively.

During the year ended December 31, 2013, the Company determined that the long-lived assets at our polycarbonate manufacturing facility in Stade, Germany should be assessed for impairment driven primarily by continued losses experienced in the Company’s polycarbonate business. This assessment indicated that the carrying amount of the long-lived assets at this facility were not recoverable when compared to the expected undiscounted cash flows of the polycarbonate business. Based upon the assessment of fair value of this asset group, the Company concluded these assets were fully impaired as of December 31, 2013. The fair value of the asset group was determined under the income approach utilizing a discounted cash flow (“DCF”) model. The key assumptions used in the DCF model included growth rates and cash flow projections, discount rate, tax rate and an estimated terminal value.

As a result, the Company recorded an impairment loss on these assets of approximately $9.2 million for the year ended December 31, 2013. The amount was recorded within “Selling, general and administrative expenses” in the consolidated statements of operations and allocated entirely to the Basic Plastics & Feedstocks segment.

Goodwill impairment testing is performed annually as of October 1st. In 2015, the Company performed its annual impairment test for goodwill and determined that the estimated fair value of each reporting unit was substantially in excess of the carrying value indicating that none of the Company’s goodwill was impaired. The Company concluded there were no goodwill impairments or triggering events for the years ended December 31, 2015, 2014, and 2013.

As of December 31, 2015, the Company had $24.5 million capitalized as software in development, primarily related to our project to upgrade our legacy ERP environment to the latest version of SAP.  This project is expected to be completed and placed into service in 2016.

In March 2014, the Company entered into an agreement with material supplier JSR Corporation, Tokyo (“JSR”) to acquire its current production capacity rights at the Company’s rubber production facility in Schkopau, Germany for a purchase price of €19.0 million (approximately $26.1 million based upon the acquisition date foreign exchange rate). Prior to this agreement, JSR held 50% of the capacity rights of one of the Company’s three solution styrene-butadiene rubber (“SSBR”) production trains in Schkopau. As a result, effective March 31, 2014, the Company had full capacity rights to this production train. The €19.0 million purchase price was recorded in “Other intangible assets, net” in the consolidated balance sheets, and is being amortized over its estimated useful life of approximately 6.0 years. Further, the purchase price was recorded within capital expenditures in investing activities in the consolidated statement of cash flows for the year ended December 31, 2014.

Amortization expense related to finite-lived intangible assets totaled $18.5 million, $19.6 million, and $15.7 million, for the years ended December 31, 2015, 2014 and 2013, respectively.

Total accrued interest on outstanding debt as of December 31, 2015 and 2014 was $7.8 million and $43.5 million, respectively. Accrued interest is recorded in “Accrued expenses and other current liabilities” within the consolidated balance sheets.

2018 Senior Secured Credit Facility

In June 2010, the Company entered into a credit agreement, which was subsequently amended on February 2, 2011, July 28, 2011, February 13, 2012, August 9, 2012, January 19, 2013, and December 3, 2013 and was set to mature in January 2018 (“2018 Senior Secured Credit Facility”).  Under the 2018 Senior Secured Credit Facility, the Company had certain term loan borrowings outstanding through the end of 2012 (the “Term Loans”). 

In January 2013, the Company amended the 2018 Senior Secured Credit Facility (the “2013 Amendment”) to, among other things, repay its then outstanding Term Loans of $1,239.0 million using the proceeds from its sale of its 2019 Senior Notes (discussed below). As a result, the Company recognized a $20.7 million loss on extinguishment of debt during the year ended December 31, 2013, which consisted of the write-off of existing unamortized deferred financing fees and debt discount attributable to the Term Loans. Fees and expenses incurred in connection with the 2013 Amendment were $5.5 million, which were capitalized.

The 2018 Senior Secured Credit Facility also included a revolving credit facility (“2018 Revolving Facility”), which, as a result of the 2013 Amendment, included a borrowing capacity of $300.0 million, with an applicable margin rate of 3.00% as applied to base rate loans (which shall bear interest at a rate per annum equal to the base rate plus the applicable margin (as defined therein)), or 4.00% as applied to LIBO rate loans (which shall bear interest at a rate per annum equal to the LIBO rate plus the applicable margin and the mandatory cost (as defined therein), if applicable), and a maturity date of January 2018. As of December 31, 2014, there were no amounts outstanding under the 2018 Revolving Facility, while available borrowings under the facility were $293.3 million (net of $6.7 million outstanding letters of credit).

Capitalized fees and costs incurred in connection with the Company’s 2018 Revolving Facility were recorded in “Deferred charges and other assets” within the consolidated balance sheets and were amortized using a straight-line method over the term of the facility. Amortization of deferred financing fees are recorded in “Interest expense, net” in the consolidated statements of operations.  Unamortized deferred financing fees related to the 2018 Revolving Facility were $8.8 million as of December 31, 2014.

The Company recorded interest expense relating to the amortization of deferred financing fees and debt discounts related to the entire 2018 Senior Secured Credit Facility, respectively, of $1.0 million and zero for the year ended December 31, 2015; $2.9 million and zero for the year ended December 31, 2014; and $3.1 million and $0.1 million for the year ended December 31, 2013.

In May 2015, upon completion of the refinancing transactions discussed below, the Company terminated the 2018 Senior Secured Credit Facility.  Immediately prior to this termination, the Company had no outstanding borrowings under the 2018 Revolving Facility. As a result of this termination, the Company recognized a $0.7 million loss on extinguishment of long-term debt, comprised entirely of the write-off of a portion of the existing unamortized deferred financing fees related to the 2018 Revolving Facility.  The remaining unamortized deferred financing fees under the 2018 Revolving Facility totaled $7.2 million, which remained capitalized and are being amortized along with the new deferred financing fees over the life of the new revolving credit facility, discussed in further detail below.

Interest charges, excluding interest expense relating to the amortization of deferred financing fees and debt discounts, incurred on the Term Loans and 2018 Revolving Facility, respectively, were zero and $0.6 million for the year ended December 31, 2015, zero and $1.8 million for the year ended December 31, 2014, and $7.7 million and $2.8 million for the year ended December 31, 2013. Cash paid related to interest incurred on the Term Loans and 2018 Revolving Facility, respectively, was zero and $0.6 million for the year ended December 31, 2015, zero and $1.9 million for the year ended December 31, 2014, and $16.5 million and $2.8 million for the year ended December 31, 2013.

Senior Credit Facility

On May 5, 2015, Trinseo Materials Operating S.C.A. and Trinseo Materials Finance, Inc. (together, the “Issuers” or the “Borrowers”), both wholly-owned subsidiaries of the Company, entered into a senior secured credit agreement (the “Credit Agreement”), which provides senior secured financing of up to $825.0 million (the “Senior Credit Facility”).  The Senior Credit Facility provides for senior secured financing consisting of a (i) $325.0 revolving credit facility, with a $25.0 million swingline subfacility and a $35.0 million letter of credit subfacility (the “2020 Revolving Facility”) maturing in May 2020 and (ii) $500.0 million senior secured term loan B facility maturing in November 2021 (the “2021 Term Loan B”). Amounts under the 2020 Revolving Facility are available in U.S. dollars and euros.

The 2021 Term Loan B bears an interest rate of LIBOR plus 3.25%, subject to a 1.00% LIBOR floor, and was issued at a 0.25% original issue discount.  Further, the 2021 Term Loan B requires scheduled quarterly payments in amounts equal to 0.25% of the original principal amount of the 2021 Term Loan B, with the balance to be paid at maturity. During the year ended December 31, 2015, the Company made principal payments of $2.5 million related to the 2021 Term Loan B. As of December 31, 2015, $5.0 million of these scheduled future payments were classified as current debt on the Company’s consolidated balance sheets.

Loans under the 2020 Revolving Facility, at the Borrowers’ option, may be maintained as (a) LIBO rate loans, which bear interest at a rate per annum equal to the LIBO rate plus the applicable margin (as defined in the Credit Agreement), if applicable, or (b) base rate loans which shall bear interest at a rate per annum equal to the base rate plus the applicable margin (as defined in the Credit Agreement).  As of December 31, 2015, the Borrowers will be required to pay a quarterly commitment fee in respect of any unused commitments under the 2020 Revolving Facility equal to 0.375% per annum.

As of December 31, 2015, the Company had no outstanding borrowings, and had $311.5 million (net of $13.5 million outstanding letters of credit) of funds available for borrowing under the 2020 Revolving Facility.

The Senior Credit Facility is collateralized by a security interest in substantially all of the assets of Trinseo Materials Operating S.C.A., as lead borrower, Trinseo Materials Finance, Inc., as co-borrower, and the guarantors thereunder including Trinseo Materials S.à r.l., certain U.S. subsidiaries and certain foreign subsidiaries organized in Luxembourg, The Netherlands, Hong Kong, Singapore, Ireland, Germany and Switzerland.

The Senior Credit Facility requires the Borrowers and their restricted subsidiaries to comply with customary affirmative and negative covenants, including limitations on their abilities to incur liens; make certain loans and investments; incur additional debt; merge, consolidate liquidate or dissolve; transfer or sell assets; pay dividends and other distributions to shareholders or make certain other restricted payments; enter into transactions with affiliates; restrict any restricted subsidiary from paying dividends or making other distributions or agree to certain negative pledge clauses; materially alter the business they conduct; prepay certain other indebtedness; amend certain material documents; and change our fiscal year.

The 2020 Revolving Facility contains a financial covenant that requires compliance with a springing first lien net leverage ratio test. If the outstanding balance under the 2020 Revolving Facility exceeds 30% of the $325.0 million borrowing capacity (excluding undrawn letters of credit up to $10.0 million and cash collateralized letters of credit) at a quarter-end, then the Company’s first lien net leverage ratio may not exceed 2.00 to 1.00.  As of December 31, 2015, the Company was in compliance with all debt covenant requirements under the Senior Credit Facility.

Fees and expenses incurred in connection with the issuance of the 2021 Term Loan B and the 2020 Revolving Facility were $12.0 million and $0.3 million, respectively, which were capitalized and recorded in “Deferred charges and other assets” in the consolidated balance sheets.

For the 2021 Term Loan B, deferred financing fees and the 0.25% debt discount are being amortized over its 6.5 year term using the effective interest method.  For the 2020 Revolving Facility, deferred financing fees (along with an additional $7.2 million of unamortized deferred financing fees from the 2018 Revolving Facility) are being amortized over its 5.0 year term using the straight-line method.  Amortization of deferred financing fees and debt discounts are recorded in “Interest expense, net” in the consolidated statements of operations.

Unamortized deferred financing fees and debt discount related to the 2021 Term Loan B were $10.9 million and $1.1 million, respectively, as of December 31, 2015. Unamortized deferred financing fees related to the 2020 Revolving Facility were $6.5 million as of December 31, 2015. The Company recorded interest expense relating to the amortization of deferred financing fees and debt discounts related to the entire Senior Credit Facility, respectively, of $2.1 million and $0.1 million for the year ended December 31, 2015.

Interest charges, excluding interest expense relating to the amortization of deferred financing fees and debt discounts, incurred on the 2021 Term Loan B and 2020 Revolving Facility, respectively, were $14.2 million and $1.3 million for the year ended December 31, 2015. Cash paid related to interest incurred on the 2021 Term Loan B and 2020 Revolving Facility, respectively, was $14.2 million and $1.3 million during the year ended December 31, 2015.

2019 Senior Notes

In January 2013, the Company issued $1,325.0 million 8.750% senior notes due to mature on February 1, 2019 (the “2019 Senior Notes”). The proceeds from the issuance of the 2019 Senior Notes were used to repay all of the Company’s then outstanding Term Loans and related refinancing fees and expenses.

In July 2014, using proceeds from the Company’s IPO (see Note 12), the Company redeemed $132.5 million in aggregate principal amount of the 2019 Senior Notes, together with a 103% call premium totaling $4.0 million and accrued and unpaid interest thereon of $5.2 million. As a result of this redemption, during the year ended December 31, 2014 the Company incurred a loss on the extinguishment of debt of approximately $7.4 million, which includes the above $4.0 million call premium and an approximately $3.4 million write-off of related unamortized deferred financing fees.

On May 13, 2015, using the net proceeds from the issuance of the 2021 Term Loan B, together with the net proceeds from the issuance of the 2022 Senior Notes (defined and discussed below) and available cash, the Company redeemed all outstanding borrowings under the 2019 Senior Notes, totaling $1,192.5 million in principal, together with a call premium of $68.6 million (with a redemption price of 103% on the first $132.5 million and 106.097% on the remaining balance) and accrued and unpaid interest thereon of $29.6 million.

As a result of this redemption, during the year ended December 31, 2015, the Company recorded a loss on extinguishment of long-term debt of $94.5 million, which includes the above $68.6 million call premium and a $25.9 million write-off of unamortized deferred financing fees related to the 2019 Senior Notes.

Fees and expenses incurred in connection with the issuance of 2019 Senior Notes were capitalized and recorded in “Deferred charges and other assets” in the consolidated balance sheets and were being amortized into “Interest expense, net” in the consolidated statements of operations over the term of the 2019 Senior Notes using the effective interest rate method.

For the year ended December 31, 2015, the Company recorded $2.1 million in amortization of deferred financing fees on the 2019 Senior Notes, noting no unamortized deferred financing fees remained on the consolidated balance sheet as of December 31, 2015 due to the redemption in May 2015. For the year ended December 31, 2014, the Company recorded $5.7 million in amortization of deferred financing fees, leaving $28.0 million of unamortized deferred financing fees related to the 2019 Senior Notes on the consolidated balance sheet as of December 31, 2014. For the year ended December 31, 2013, the Company recorded $4.9 million in amortization of deferred financing fees.

Interest expense on the 2019 Senior Notes, excluding expense relating to the amortization of deferred financing fees, was $38.3 million, $110.6 million, and $106.9million for the years ended December 31, 2015, 2014, and 2013, respectively. Cash paid for interest on the 2019 Senior Notes was $81.7 million, $115.4 million, and $58.6 million for the years ended December 31, 2015, 2014, and 2013, respectively.

2022 Senior Notes

On May 5, 2015, the Issuers executed an indenture (the “Indenture”) pursuant to which they issued $300.0 million aggregate principal amount of 6.750% senior notes due May 1, 2022 (the “USD Notes”) and €375.0 million aggregate principal amount of 6.375% senior notes due May 1, 2022 (the “Euro Notes”, and together with the USD Notes, the “2022 Senior Notes”).  Interest on the 2022 Senior Notes is payable semi-annually on May 1 and November 1 of each year, commencing on November 1, 2015.

At any time prior to May 1, 2018, the Issuers may redeem the Euro Notes and/or the USD Notes in whole or in part, at their option at a redemption price equal to 100% of the principal amount of such notes plus the relevant applicable premium as of, and accrued and unpaid interest to, but not including, the redemption date. At any time and from time to time after May 1, 2018, the Issuers may redeem the Euro Notes and/or the USD Notes, in whole or in part, at a redemption price equal to the percentage of principal amount set forth below plus accrued and unpaid interest, if any, on the notes redeemed to, but not including, the redemption date:  

	Euro Notes		USD Notes
12-month period commencing May 1 in Year	Percentage		Percentage
2018	103.188	%	103.375	%
2019	101.594	%	101.688	%
2020 and thereafter	100.000	%	100.000	%

In addition, at any time prior to May 1, 2018, the Issuers may redeem up to 40% of the aggregate principal amount of each of the USD Notes and the Euro Notes, either together or separately, at a redemption price equal to 106.750% of the principal amount thereof for the USD Notes and 106.375% of the principal amount thereof for the Euro Notes plus, in each case, accrued and unpaid interest to, but not including, the redemption date, in an amount equal to the aggregate gross proceeds from certain equity offerings.

The 2022 Senior Notes are the Issuers’ senior unsecured obligations and rank equally in right of payment with all of the Issuers’ existing and future indebtedness that is not expressly subordinated in right of payment thereto. The 2022 Senior Notes will be senior in right of payment to any future indebtedness that is expressly subordinated in right of payment thereto and effectively junior to (a) the Issuers’ existing and future secured indebtedness, including the Company’s accounts receivable facility and the Issuers’ Senior Credit Facility (discussed above), to the extent of the value of the collateral securing such indebtedness and (b) all existing and future liabilities of the Issuers’ non-guarantor subsidiaries.

The Indenture contains customary covenants that, among other things, limit the Issuers’ and certain of their subsidiaries’ ability to incur additional indebtedness and guarantee indebtedness, pay dividends or make other distributions, make investments, or prepay certain indebtedness, each subject to a number of exceptions and qualifications. Certain of these covenants, will be suspended during any period of time that (1) the 2022 Notes have investment grade ratings (as defined in the Indenture) and (2) no default has occurred and is continuing under the Indenture. In the event that the 2022 Senior Notes are downgraded to below an investment grade rating, the Issuers and certain subsidiaries will again be subject to the suspended covenants with respect to future events. As of December 31, 2015, the Company was in compliance with all debt covenant requirements under the Indenture.

Fees and expenses incurred in connection with the issuance of the 2022 Senior Notes were $16.0 million, which were capitalized and recorded in “Deferred charges and other assets” in the consolidated balance sheets, and are being amortized into “Interest expense, net” in the consolidated statements of operations over their 7.0 year term using the effective interest method.

For the year ended December 31, 2015, the Company recorded $1.2 million in amortization of deferred financing fees, leaving $14.8 million of unamortized deferred financing fees on the consolidated balance sheet as of December 31, 2015.

Interest expense on the 2022 Senior Notes, excluding expense relating to the amortization of deferred financing fees, was $30.5 million for the year ended December 31, 2015. Cash paid for interest on the 2022 Senior Notes was $22.8 million for the year ended December 31, 2015.

Accounts Receivable Securitization Facility

In 2010, Styron Receivable Funding Ltd. (“SRF”), a VIE in which the Company is the primary beneficiary, executed an agreement for an accounts receivable securitization facility (“Accounts Receivable Securitization Facility”). As of December 31, 2015, the facility, as previously amended in May 2013, permitted borrowings by one of the Company’s subsidiaries, Trinseo Europe GmbH (“TE”), up to a total of $200.0 million and had a maturity date of May 2016.  In February 2016, the facility was again amended, extending the maturity date to May 2019.

Under the facility, TE sells its accounts receivable from time to time to SRF. In turn, SRF may sell undivided ownership interests in such receivables to commercial paper conduits in exchange for cash. The Company has agreed to continue servicing the receivables for SRF. Upon the sale of the interests in the accounts receivable by SRF, the conduits have a first priority perfected security interest in such receivables and, as a result, the receivables will not be available to the creditors of the Company or its other subsidiaries.

The Accounts Receivable Securitization Facility is subject to interest charges against the amount of outstanding borrowings as well as the amount of available, but undrawn commitments. In regards to outstanding borrowings, fixed interest charges are 2.6% plus variable commercial paper rates, while for available, but undrawn commitments, fixed interest charges are 1.40%.  

As of December 31, 2015 and 2014, there were no amounts outstanding under the Accounts Receivable Securitization Facility, with approximately $123.4 million and $136.1 million, respectively, of funds available for borrowing under this facility, based on the pool of eligible accounts receivable. Interest expense on the Accounts Receivable Securitization Facility, excluding interest expense relating to the amortization of deferred financing fees, for the years ended December 31, 2015, 2014 and 2013 was $2.8 million, $2.9 million and $4.2 million, respectively, and was recorded in “Interest expense, net” in the consolidated statements of operations.

Unamortized deferred financing fees related to the Accounts Receivable Securitization Facility were $0.5 million and $1.9 million as of December 31, 2015 and 2014, respectively, recorded in “Deferred charges and other assets” within the consolidated balance sheets. These charges are being amortized on a straight-line basis over the term of the facility. The Company recorded $1.2 million, $1.4 million and $1.4 million in amortization of deferred financing fees related to the Accounts Receivable Securitization Facility in “Interest expense, net” within the consolidated statements of operations for the years ended December 31, 2015, 2014 and 2013, respectively.

Other Indebtedness

The Company has a short-term revolving facility through our subsidiary in China that provides uncommitted funds available for borrowing, subject to the availability of collateral. The facility is subject to annual renewal.

Outstanding borrowings under this revolving facility were zero and $7.6 million as of December 31, 2015 and 2014, respectively. The revolving facility is guaranteed by the Company’s holding company, Trinseo Materials Operating S.C.A. or secured by pledge of certain of the Company’s assets in China. As of December 31, 2015 and 2014, the weighted average interest rate of the facility was approximately zero and 0.1%, respectively.

Derivative Instruments [Abstract]

Derivative Instruments

NOTE 11—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 consolidated balance sheets at fair value. For fair value disclosures related to these instruments refer to Note 13.

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 December 31, 2015, the Company had open foreign exchange forward contracts with a net notional U.S. dollar equivalent absolute value of $371.8 million. The following table displays the notional amounts of the most significant net foreign exchange hedge positions outstanding as of December 31, 2015.

	December 31,
Buy / (Sell)	2015
Chinese Yuan	$	(122,907)
Euro	$	109,049
Indonesian Rupiah	$	(58,212)
Swiss Franc	$	36,856
British Pound	$	(16,124)

Open foreign exchange forward contracts as of December 31, 2015 have maturities of less than three months.

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 (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 December 31, 2015 have maturities occurring over a period of 12 months, and have a net notional U.S. dollar equivalent of $168.0 million.

Net Investment Hedge

The Company’s outstanding debt includes €375.0 million of Euro Notes (see Note 10 for details).  As of December 31, 2015, the Company has designated a portion (€150.0 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 gain of$0.4 million within accumulated other comprehensive loss as of December 31, 2015.

Summary of Derivative Instruments

Information regarding changes in the fair value of the Company’s derivative instruments, including those not designated for hedge accounting treatment, is as follows:

The Company recorded losses of $16.5 million, $28.2 million and $0.6 million during the years ended December 31, 2015, 2014, and 2013, respectively, from settlements and changes in the fair value of outstanding forward contracts (not designated as hedges) which are recognized in “Other expense, net” in the consolidated statements of operations. The losses from these forward contracts offset net foreign exchange transaction gains of $6.1 million and $32.4 million during the years ended December 31, 2015 and 2014, respectively, and were incremental to net foreign exchange transaction losses of $18.3 million during the year ended December 31, 2013, 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 consolidated statements of cash flows.

As of December 31, 2015, the Company has no ineffectiveness related to its foreign exchange cash flow hedges. In the next twelve months, the Company expects to reclassify an approximate $5.0 million net gain from other comprehensive income (loss) into earnings related to the Company’s outstanding cash flow hedges as of December 31, 2015, based on current foreign exchange rates.

The following table summarizes the net unrealized gains and losses and balance sheet classification of outstanding derivatives recorded in the consolidated balance sheets:

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 consolidated balance sheet. Information regarding the gross amounts of the Company’s derivative instruments and the amounts offset in the consolidated balance sheets is as follows:

NOTE 12—SHAREHOLDERS’ EQUITY

Ordinary Shares

On May 30, 2014, the Company amended its Articles of Association to effect a 1-for-436.69219 reverse split of its issued and outstanding ordinary shares and to increase its authorized ordinary shares to 50.0 billion. Pursuant to the reverse split, every 436.69219 shares of the Company’s then issued and outstanding ordinary shares was converted into one ordinary share. The reverse split did not change the par value of the Company’s ordinary shares. These consolidated financial statements and accompanying footnotes have been retroactively adjusted to give effect to the reverse split.

On June 17, 2014, the Company completed the IPO of 11,500,000 ordinary shares at a price of $19.00 per share. The number of ordinary shares at closing included 1,500,000 of shares sold pursuant to the underwriters’ over-allotment option. The Company received cash proceeds of $203.2 million from this transaction, net of underwriting discounts. These net proceeds were used by the Company for: i) the July 2014 repayment of $132.5 million in aggregate principal amount of the 8.750% Senior Notes due 2019, together with accrued and unpaid interest thereon of $5.2 million and a call premium of $4.0 million (see Note 10); ii) the payment of approximately $23.3 million in connection with the termination of the Advisory Agreement with Bain Capital (see Note 18); iii) the payment of approximately $5.1 million of advisory, accounting, legal and printing expenses directly related to the offering which were recorded as a reduction to additional paid-in capital in the consolidated balance sheets; and iv) general corporate purposes.

Fair Value Measurements

NOTE 13—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 consolidated balance sheets at December 31, 2015 and 2014.

The Company uses an income approach to value its foreign exchange forward contracts and foreign exchange cash flow hedges, 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 within 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 December 31, 2015 and 2014, respectively:

As of December 31, 2015 and 2014, all undistributed earnings of foreign subsidiaries and affiliates are expected to be repatriated. Operating loss carryforwards amounted to $263.9 million in 2015 and $227.8 million in 2014. As of December 31, 2015, $37.5 million of the operating loss carryforwards were subject to expiration in 2016 through 2020, and $226.4 million of the operating loss carryforwards expire in years beyond 2020 or have an indefinite carryforward period. As of December 31, 2015, the Company had tax credit carryforwards of $3.2 million relating to U.S. foreign tax credits, of which a portion will begin to expire in 2023.

The Company had valuation allowances which were related to the realization of recorded tax benefits on tax loss carryforwards, as well as other net deferred tax assets, primarily from subsidiaries in Luxembourg and Australia, of $85.1 million as of December 31, 2015 and $66.9 million as of December 31, 2014.  In addition, the Company recorded a valuation allowance of $7.3 million on the net deferred tax asset of one of its China subsidiaries during the fourth quarter of 2015, as this entity was in a three year cumulative loss position as of December 31, 2015 and the Company could no longer assert it would more likely than not be able to realize its deferred tax asset.  If in the future, this subsidiary generates sufficient profitability such that the evaluation of recoverability of the deferred tax asset changes, the valuation allowance could be reversed.  

For the years presented, a reconciliation of the beginning and ending amount of the unrecognized tax benefits is as follows:

Balance as of December 31, 2012	$	30,079
Increases related to current year tax positions		1,225
Decreases related to prior year tax positions		(4,405)
Balance as of December 31, 2013	$	26,899
Increases related to current year tax positions		187
Decreases related to prior year tax positions		(6,701)

Increases related to current year tax positions		1,304
Decreases related to prior year tax positions		(1,647)
Balance as of December 31, 2015	$	20,042

The Company recognized interest and penalties of $0.7 million, less than $0.1 million, and $0.7 million for the years ended December 31, 2015, 2014, and 2013, respectively, which was included as a component of income tax expense in the consolidated statements of operations. As of December 31, 2015 and 2014, the Company had $2.3 million and $1.8 million, respectively, accrued for interest and penalties. To the extent that the unrecognized tax benefits are recognized in the future, $16.7 million will impact the Company’s effective tax rate. In addition, the Company estimates that approximately $1.0 million of current unrecognized tax benefits may be realized within the next twelve months as the result of a lapse of statute limitations.

As a majority of the Company’s legal entities had no significant activity prior to or were formed in 2010, only the 2010 tax year and forward is subject to examination in the majority of jurisdictions, except for China, Hong Kong, and Indonesia where tax years between 2007 and 2009 remain subject to examination. Pursuant to the terms of the Purchase Agreement, the Company has been indemnified from and against any taxes for or with respect to any periods prior to the Acquisition.

Commitments and Contingencies

NOTE 15—COMMITMENTS AND CONTINGENCIES

Leased Property

The Company routinely leases premises for use as sales and administrative offices, warehouses and tanks for product storage, motor vehicles, railcars, computers, office machines, and equipment under operating leases. Rental expense for these leases was $18.4 million, $15.9 million and $16.2 million during the years ended December 31, 2015, 2014, and 2013, respectively.

Future minimum rental payments under operating leases with remaining non-cancelable terms in excess of one year are as follows:

	Annual
Year	Commitment
2016	$	8,959
2017		6,660
2018		6,207
2019		5,835
2020		4,273
Thereafter		7,637
Total	$	39,571

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. As of December 31, 2015 and 2014, the Company had no accrued obligations for environmental remediation and restoration costs. Pursuant to the terms of the Acquisition, the pre-closing environmental conditions were retained by Dow and the Company has been indemnified by Dow from and against all environmental liabilities incurred or relating to the predecessor periods. There are several properties which the Company now owns on which Dow has been conducting investigation, monitoring, or remediation to address historical contamination. Those properties include Allyn’s Point, Connecticut, Dalton, Georgia, and Livorno, Italy. There are other properties with historical contamination that are owned by Dow that the Company leases for its operations, including its facilities in Midland, Michigan, Schkopau, Germany, Terneuzen, The Netherlands, and Guaruja, Brazil. No environmental claims have been asserted or threatened against the Company, and the Company is not a potentially responsible party at any Superfund Sites.

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 consolidated financial statements.

There were no amounts recorded in the consolidated statement of operations relating to environmental remediation for the years ended December 31, 2015, 2014, and 2013.

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. The following table presents the fixed and determinable portion of the obligation under the Company’s purchase commitments as of December 31, 2015 (in millions):

	Annual
Year	Commitment
2016	$	1,312
2017		1,035
2018		1,175
2019		922
2020		1,026
Thereafter		—
Total	$	5,470

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 obligations shown in the table above.

The Company has service agreements with Dow and Bain Capital, some of which contain fixed annual fees. See Note 18 for further discussion.

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.

Pension Plans and Other Postretirement Benefits

Pension Plans and Other Postretirement Benefits

Pension Plans and Other Postretirement Benefits

NOTE 16—PENSION PLANS AND OTHER POSTRETIREMENT BENEFITS

Defined Benefit Pension Plans

Many of the Company’s employees are participants in various defined benefit pension plans which are administered and sponsored by the Company and are primarily in Germany, Switzerland, The Netherlands, Belgium and Japan.

In connection with the Acquisition, the Company and Dow entered into affiliation agreements in certain jurisdictions (the “Affiliation Agreements”) allowing employees who transferred from Dow to the Company as of June 17, 2010 to remain in the Dow operated pension plans (“Dow Plans”) until the Company established its own pension plan. The Company then made the required employer contribution amounts to the Dow Plans for the Company’s employees and the related pension benefit obligations for the Company’s employees have been accumulating in the Dow Plans since the Acquisition Date. Since June 2010, the Dow Plans originally established in those jurisdictions, were gradually legally separated into the Company’s self administered and sponsored plans until the Affiliation Agreements ended on December 31, 2012.

In Switzerland and The Netherlands, all remaining employees of the Company who were previously participants of the Dow Plans transferred to separately administered and sponsored pension plans of the Company effective January 1, 2013 (the “Successor Plans”). The benefit obligation and related plan assets in the Dow Plans belonging to the Company’s employees were transferred to the Successor Plans. As a result of the transfer, the Company recognized prior service credits and net losses of approximately $13.0 million and $1.4 million, respectively in other comprehensive income during the year ended December 31, 2013.

Company employees who were not previously associated with the acquired pension and postretirement plans are generally not eligible for enrollment in these plans. Pension benefits are typically based on length of service and the employee’s final average compensation.

Other Postretirement Benefits

The Company, either through a Company benefit plan or government-mandated benefits, provides certain health care and life insurance benefits applicable primarily to Dow-heritage retired employees, primarily in the U.S., as well as in Brazil.

In the U.S., the plan provides for health care benefits, including hospital, physicians’ services, drug and major medical expense coverage. In general, the plan applies to employees hired by Dow before January 1, 2008 and transferred to the Company in connection with the Acquisition, and who are at least 50 years old with 10 years of service. The plan allows for spouse coverage as well. If an employee was hired on or before January 1, 1993, the coverage extends past age 65. For employees hired after January 1, 1993 but before January 1, 2008, coverage ends at age 65. The Company reserves the right to modify the provisions of the plan at any time, including the right to terminate, and does not guarantee the continuation of the plan or its provisions.

In Brazil, the Company provides an insured medical benefit to all employees and eligible dependents under Brazil’s healthcare legislation, which grants the right to employees (and their beneficiaries) who have contributed towards the medical plan to extend medical coverage upon retirement or in case of involuntary dismissal. The extended medical plan must include the same level of coverage and other conditions offered to active employees, whereas former employees must assume 100% of the premium cost. Prior to 2014, the Company had not accrued for the postretirement benefits owed under this plan. As a result, for the year ended December 31, 2014, a $2.7 million liability was recorded, which includes an adjustment related to the original purchase price allocation from the Acquisition as a portion of this obligation was assumed from Dow. The impact of this adjustment was a $1.7 million increase to goodwill and $1.0 million of net periodic benefit costs, net of currency remeasurement gains, incurred from the date of the Acquisition through December 31, 2013. The Company does not believe these adjustments were material to any prior period financial statements.

In The Netherlands, the Company previously provided postretirement medical benefits to Dow-heritage employees who transferred to the Company in connection with the Acquisition. The Company ceased providing these benefits effective January 1, 2015. As a result, the Company recognized approximately $1.5 million of curtailment gain for the year ended December 31, 2014.

Assumptions

The weighted-average assumptions used to determine pension plan obligations and net periodic benefit costs are provided below:

	Pension Plan Obligations						Net Periodic Benefit Costs
	December 31,						December 31,
	2015		2014		2013		2015		2014		2013
Discount rate	2.06	%	2.01	%	3.30	%	2.01	%	3.30	%	3.05	%
Rate of increase in future compensation levels	2.68	%	2.71	%	2.86	%	2.71	%	2.86	%	2.69	%
Expected long-term rate of return on plan assets	N/A		N/A		N/A		1.73	%	2.83	%	2.44	%

The weighted-average assumptions used to determine other postretirement benefit (“OPEB”) obligations and net periodic benefit costs are provided below:

	OPEB Obligations						Net Periodic Benefit Costs
	December 31,						December 31,
	2015		2014		2013		2015		2014		2013
Discount rate	6.51	%	6.40	%	4.72	%	6.40	%	6.69	%	3.93	%
Initial health care cost trend rate	8.19	%	8.05	%	6.67	%	8.05	%	6.67	%	7.00	%
Ultimate health care cost trend rate	5.26	%	5.43	%	5.00	%	5.43	%	5.00	%	5.00	%
Year ultimate trend rate to be reached	2023		2021		2019		2021		2019		2019

The discount rate utilized to measure the pension and other postretirement benefit plans is based on the yield of high-quality fixed income debt instruments at the measurement date. Future expected, actuarially determined cash flows of the plans are matched against a yield curve to arrive at a single discount rate for each plan.

The expected long-term rate of return on plan assets is determined by performing a detailed analysis of key economic and market factors driving historical returns for each asset class and formulating a projected return based on factors in the current environment. Factors considered include, but are not limited to, inflation, real economic growth, interest rate yield, interest rate spreads, and other valuation measures and market metrics. The expected long-term rate of return for each asset class is then weighted based on the strategic asset allocation approved by the governing body for each plan. The historical experience with the pension fund asset performance is also considered.

A  one-percentage point change in the assumed health care cost trend rate would have had a nominal effect on both service and interest costs, but would result in an approximate $0.7 million impact to the projected benefit obligation.

The net periodic benefit costs for the pension and other postretirement benefit plans for the years ended December 31, 2015, 2014, and 2013 were as follows:

	Defined Benefit Pension Plans									Other Postretirement Benefit Plans

(1) This amount represents settlement losses from one of the Company’s defined benefit plans in Switzerland due to the termination of certain employees during the year, which resulted in a loss recognized in the year ended December 31, 2014 due to a charge against the unamortized net loss recorded in other comprehensive income.

(2) This amount represents a curtailment loss from one of the Company’s defined benefit plans in Germany due to the reduction or cessation of benefit accruals for certain employees’ future services. The adjustment in the benefit obligation from the curtailment resulted in a loss recognized during the year ended December 31, 2013 due to a charge against the unamortized net loss recorded in other comprehensive income.

(3) This amount represents a curtailment gain from the Company’s other postretirement benefit plan in The Netherlands, due to the cessation of retiree medical benefit accruals effective January 1, 2015.

(4) This adjustment was made to the Company’s pension plan in The Netherlands to reflect the introduction of a salary cap and lower accrual rate on pension benefits as a result of tax law changes effective January 1, 2015. The impact of the change resulted in an adjustment to prior service credit in other comprehensive income as of December 31, 2014, which will be amortized to net periodic benefit cost over the estimated remaining service period of the employees.

(5) This is primarily related to the transfer of all remaining employees who were previously participants in the Dow Plans in Switzerland and The Netherlands to Company Successor Plans effective January 1, 2013, as discussed above.

(6) These amounts include the prior period net periodic cost and other comprehensive income components of the postretirement benefits in Brazil recognized during 2014, as discussed above.

(7) This amount is primarily related to a reduction in annuity conversion rates announced by the insurance provider for the pension plans in Switzerland. The impact of the change resulted in an adjustment to prior service credit in other comprehensive income as of December 31, 2015, which will be amortized to net periodic benefit cost over the estimated remaining service period of the employees.

The changes in the pension benefit obligations and the fair value of plan assets and the funded status of all significant plans for the year ended December 31, 2015 and 2014 were as follows:

Plan Assets

As of December 31, 2015 and 2014, respectively, plan assets totaled $100.5 million and $92.6 million, consisting of investments in insurance contracts. Investments in the pension plan insurance were valued utilizing unobservable inputs, which are contractually determined based on cash surrender values, returns, fees, and the present value of the future cash flows of the contracts.

Insurance contracts are classified as Level 3 investments. Changes in the fair value of these level 3 investments during the years ended December 31, 2015 and 2014 are included in the “Change in plan assets” table above.

Concentration of Risk

The Company mitigates the credit risk of investments by establishing guidelines with investment managers that limit investment in any single issue or issuer to an amount that is not material to the portfolio being managed. These guidelines are monitored for compliance both by the Company and external managers. Credit risk related to derivative activity is mitigated by utilizing multiple counterparties and through collateral support agreements.

Supplemental Employee Retirement Plan

The Company established a non-qualified supplemental employee retirement plan in 2010. The net benefit costs recognized for the years ended December 31, 2015, 2014, and 2013 were $1.0 million, $1.3 million, and $2.3 million, respectively. Benefit obligations under this plan were $13.7 million and $13.2 million as of December 31, 2015 and 2014, respectively. As of December 31, 2015 and 2014, the amounts of net loss included in AOCI were $1.6 million and $2.0 million, respectively, with $0.8 million amortized from AOCI into net periodic benefit costs during each of the years ended December 31, 2015 and 2014, respectively. Approximately $1.0 million is expected to be amortized from AOCI into net periodic benefit cost in 2016.

Based on the Company’s current estimates, the estimated future benefit payments under this plan, reflecting expected future service, as appropriate, are presented in the following table:

	2016		2017		2018		2019		2020		Thereafter		Total
Supplemental employee retirement plan	$	—	$	13,855	$	—	$	—	$	—	$	—	$	13,855

Defined Contribution Plans

The Company also offers defined contribution plans to eligible employees in the U.S. and in other countries, including China, Brazil, Hong Kong, Korea, The Netherlands, Taiwan and the United Kingdom. The defined contribution plans are comprised of a non-discretionary elective matching contribution component as well as a discretionary non-elective contribution component. Employees participate in the non-discretionary component by contributing a portion of their eligible compensation to the plan, which is partially matched by the Company. Non-elective contributions are made at the discretion of the Company and are based on a combination of eligible employee compensation and performance award targets. For the years ended December 31, 2015, 2014, and 2013, respectively, the Company contributed $7.8 million, $6.8 million, and $6.3 million to the defined contribution plans.

Stock-Based Compensation

Stock-Based Compensation

NOTE 17—STOCK-BASED COMPENSATION

Restricted Stock Awards issued by the Parent

On June 17, 2010, the Parent authorized the issuance of up to 750,000 shares in time-based and performance-based restricted stock to certain key members of management. Any related compensation associated with these awards is allocated to the Company from the Parent. With the adoption of the Trinseo S.A. 2014 Omnibus Incentive Plan (“2014 Omnibus Plan”) during 2014, discussed further below, restricted stock awards will no longer be issued by the Parent on behalf of the Company.

Time-based Restricted Stock Awards

The time-based restricted stock awards issued by the Parent contain a service-based condition that requires continued employment with the Company. Generally, these awards vest over three to five years of service, with a portion (20% to 40%) cliff vesting after the first one or two years. The remaining portion of the awards vest ratably over the subsequent service period, subject to the participant’s continued employment with the Company, and vest automatically upon a change in control of the Company, excluding a change in control related to an IPO. Should a participant’s termination occur within a defined timeframe due to death or permanent disability, a termination of the participant by the Company or one of its subsidiaries without cause, or the participant’s voluntary resignation for good reason, the portion of awards that are subject to time-based vesting that would have vested on the next regular vesting date will accelerate and vest on a pro rata basis, based on the number of full months between the last regular vesting date and the termination date.

The Parent has a call right that gives it the option, but not the obligation, to repurchase vested stock at the then current fair value upon an employee’s termination, or at cost in certain circumstances. During the year ended December 31, 2013, as the result of certain employee terminations, the Parent repurchased a total of 3,372 previously vested time-based restricted stock awards at cost, resulting in a $0.9 million favorable adjustment to stock-based compensation expense. No such events occurred in 2015 or 2014.

Compensation cost for the time-based restricted stock awards is measured at the grant date based on the fair value of the award (discussed below) and is recognized as expense over the appropriate service period utilizing graded vesting.

Total compensation expense for time-based restricted stock awards was $2.5 million, $7.0 million, and $8.3 million for the years ended December 31, 2015, 2014, and 2013, respectively. As of December 31, 2015, there was $1.6 million of total unrecognized compensation cost related to time-based restricted stock awards, which is expected to be recognized over a weighted-average period of 1.7 years.

The following table summarizes the activity in the Parent’s time-based restricted stock awards during the year ended December 31, 2015:

		Weighted-Average

(1) There were no grants of time-based restricted stock awards by the Parent during the years ended December 31, 2015 and 2014 as a result of the adoption of the 2014 Omnibus Plan, as discussed below.

Modified Time-based Restricted Stock Awards

In periods prior to June 2014, the performance-based restricted stock awards issued by the Parent contained provisions wherein vesting was subject to the full satisfaction of both time and performance vesting criterion. The performance component of the awards could only be satisfied if certain targets were achieved based on various returns realized by the Company’s shareholders on a change in control or an IPO. The time vesting requirements for the performance-based restricted stock awards generally vested in the same manner as the related time-based award. Prior to the Company’s IPO in June 2014, the Company had not recorded any compensation expense related to these awards as the likelihood of achieving the existing performance condition of a change in control or IPO was not deemed to be probable.

On June 10, 2014, prior to the completion of the Company’s IPO, the Parent entered into agreements to modify the outstanding performance-based restricted stock awards held by the Company’s employees to remove the performance-based vesting condition associated with such awards related to the achievement of certain investment returns (while maintaining the requirement for a change in control or IPO). This modification also changed the time-based vesting requirement associated with such shares to provide that any shares which would have satisfied the time-based vesting condition previously applicable to such shares on or prior to June 30, 2017 will instead vest on June 30, 2017, subject to the holder remaining continuously employed by the Company through such date. Any such shares that are subject to a time-based vesting condition beyond June 30, 2017 will remain subject to the time-based vesting condition previously applicable to such awards. Henceforth, these awards have been described as the Company’s modified time-based restricted stock awards.

On June 17, 2014, with the completion of the Company’s IPO, the remaining performance condition associated with these modified time-based restricted stock awards was achieved. As a result, the Company began recognizing compensation expense on these awards, which was measured at the modification date based on the fair value of the awards and is being recognized as expense over the appropriate service period utilizing graded vesting.

Total compensation expense recognized for modified time-based restricted stock awards was $2.4 million and $2.5 million for the years ended December 31, 2015 and 2014, respectively.As of December 31, 2015, there was $4.5 million of total unrecognized compensation cost related to modified time-based restricted stock awards, which is expected to be recognized over a weighted-average period of 1.6 years.

The following table summarizes the activity in the Parent’s modified time-based restricted stock awards during the year ended December 31, 2015:

		Weighted-Average

(1) There were no grants of performance-based restricted stock awards (or modified time-based restricted stock awards) by the Parent during the years ended December 31, 2015 and 2014 as a result of the adoption of the 2014 Omnibus Plan, as discussed below.

Fair Value Assumptions for Restricted Stock Award Grants

There were no grants by the Parent of time-based, performance-based, or modified time-based restricted stock awards during the years ended December 31, 2015 and 2014. However, as a result of the above-described June 2014 modification, the fair value of all modified time-based restricted stock awards was calculated as of the modification date. The fair values of time-based, modified time-based, and performance-based restricted stock awards (in prior years) were estimated on the date of grant using a combination of a call option and digital option model that uses assumptions about expected volatility, risk-free interest rates, the expected term, and dividend yield. In valuations performed prior to the IPO the expected term for performance-based awards considered management’s probability-weighted estimate of the expected time until a change in control or IPO as well as the time until a performance condition would be met. The expected term for time-based and modified time-based awards considered both the service conditions of vesting of the awards, as well as management’s probability-weighted estimate of the expected liquidity horizon. The expected volatilities were based on a combination of implied and historical volatilities of a peer group of companies, as the Company was a non-publicly traded company prior to the IPO. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with the expected life of the awards. The expected dividend yield was based on an assumption that no dividends were expected to be declared in the near future.

The following are the weighted average assumptions used for grants during the year ended December 31, 2013 and for valuation of the modified time-based awards in June 2014 (noting no grants or modifications during the year ended December 31, 2015):

	Year Ended December 31,
	2014		2013
Dividend yield	—	%	—	%
Expected volatility	65.00	%	73.25	%
Risk-free interest rate	1.54	%	0.52	%
Expected term (in years) for performance-based shares	N/A		3.85
Expected term (in years) for time-based and modified time-based shares	4.50		9.21

2014 Omnibus Plan

In connection with the IPO, the Company’s board of directors approved the 2014 Omnibus Plan, adopted on May 28, 2014, under which the maximum number of ordinary shares that may be delivered upon satisfaction of awards granted under such plan is 4.5 million shares. Following the IPO, all equity-based awards granted by the Company will be granted under the 2014 Omnibus Plan, which provides for awards of stock options, share appreciation rights, restricted stock, unrestricted stock, stock units, performance awards, cash awards and other awards convertible into or otherwise based on ordinary shares of the Company.  

During 2014, a limited number of awards were granted under the 2014 Omnibus Plan, noting grants of restricted share units (“RSUs”) to two of the Company’s directors.  During 2015, the board of directors of the Company approved a more broad-based equity award grant for directors and certain executives and employees, comprised of RSUs and options to purchase shares (“option awards”).

Restricted Share Units (RSUs)

The RSUs granted to executives and employees vest in full on the third anniversary of the date of grant, generally subject to the employee remaining continuously employed by the Company on the vesting date. RSUs granted to directors of the Company vest in full on the first anniversary of the date of grant.  Upon a termination of employment due to the employee’s death or retirement or a termination of employment by the Company without cause in connection with a restructuring or redundancy or due to the employee’s disability prior to the vesting date, the RSUs will vest in full or in part, depending on the type of termination. In the event employment is terminated for cause, all unvested RSUs will be forfeited. Dividends and dividend equivalents will not accumulate on unvested RSUs. Compensation costs for the RSUs are measured at the grant date based on the fair value of the award and are recognized ratably as expense over the applicable vesting term.

The fair value of RSUs is equal to the fair market value of the Company’s ordinary shares based on the closing price on the date of grant.

Total compensation expense for the RSUs was $2.1 million and $0.1 million for the years ended December 31, 2015 and 2014, respectively. As of December 31, 2015, there was $5.7 million of total unrecognized compensation cost related to the RSUs, which is expected to be recognized over a weighted-average period of 2.1 years. The following table summarizes the award activity for RSUs during the year ended December 31, 2015:

		Weighted-Average
		Grant Date
Restricted Share Units	Shares	Fair Value per Share

(1) No RSUs vested during the year ended December 31, 2014.

Option Awards

The option awards, which contain an exercise term of nine years from the date of grant, vest in three equal annual installments beginning on the first anniversary of the date of grant, generally subject to the employee remaining continuously employed on the applicable vesting date. Upon a termination of employment due to the employee’s death or retirement or a termination of employment by the Company without cause in connection with a restructuring or redundancy or due to the employee’s disability prior to a vesting date, the options will vest in full or will continue to vest on the original vesting schedule, depending on the type of termination. In the event employment is terminated for cause, all vested and unvested options will be forfeited. Compensation cost for the option awards is measured at the grant date based on the fair value of the award and is recognized as expense over the appropriate service period utilizing graded vesting.

The fair value for option awards is computed using the Black-Scholes pricing model, whose inputs and assumptions are determined as of the date of grant. Determining the fair value of the option awards requires considerable judgment, including estimating the expected term of stock options and the expected volatility of the price of the Company’s ordinary shares.

Since the Company’s equity interests were privately held prior to the IPO in June 2014, there is limited publicly traded history of the Company’s ordinary shares, and as a result the expected volatility used in the Black-Scholes pricing model is based on the historical volatility of similar companies’ stock that are publicly traded as well as the Company’s debt-to-equity ratio. Until such time that the Company has enough publicly traded history of its ordinary shares to determine expected volatility based solely on its ordinary shares, estimated volatility of options granted will be based on a combination of our historical volatility and similar companies’ stock that are publicly traded. The expected term of options represents the period of time that options granted are expected to be outstanding. For the grants presented herein, the simplified method was used to calculate the expected term of options, given the Company’s limited historical exercise data. The risk-free interest rate for the periods within the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The dividend yield is assumed to be zero based on historical and expected dividend activity.

The following are the weighted-average assumptions used within the Black-Scholes pricing model for grants during the year ended December 31, 2015:

	Year Ended December 31,
	2015
Dividend yield	—	%
Expected volatility	45.00	%
Risk-free interest rate	1.65	%
Expected term (in years)	5.50

Total compensation expense for the option awards was $3.0 million for the year ended December 31, 2015. As of December 31, 2015, there was $1.3 million of total unrecognized compensation cost related to the option awards, which is expected to be recognized over a weighted-average period of 1.0 years. The following table summarizes the award activity for option awards during the year ended December 31, 2015:

(1) No option awards vested during the year ended December 31, 2015.

Management Retention Awards

During the year ended December 31, 2012, the Parent agreed to retention awards with certain officers. These awards generally vest over one to four years, and are payable upon vesting subject to the participant’s continued employment with the Company on the vesting date. Compensation expense related to these retention awards is equivalent to the value of the award, and is recognized ratably over the applicable service period. Total compensation expense for these retention awards was $0.9 million and $1.4 million for the years ended December 31, 2014 and 2013, respectively, while for the year ended December 31, 2015 a net benefit of $1.1 million was recorded due to certain employment terminations, resulting in forfeited retention awards. As of December 31, 2015, there was no unrecognized compensation cost related to these retention awards.

Parent Company Restricted Stock Sales

During the year ended December 31, 2013, the Parent sold 779 shares of non-transferable restricted stock to certain employees, all of which were sold at a purchase price less than the fair value of the Parent’s common stock. As a result, during the year ended December 31, 2013, the Company recorded compensation expense of approximately $0.2 million related to these restricted stock sales. There were no restricted stock sales during the years ended December 31, 2015 and 2014. The restricted stock may not be transferred without the Parent’s consent, except for a sale to the Parent or its investors in connection with a termination or on an IPO or other liquidation event.

Summary of Stock-based Compensation Expense

The amount of stock-based compensation expense recorded within “Selling, general and administrative expenses” in the consolidated statements of operations for the years ended December 31, 2015, 2014, and 2013, respectively, was as follows:

NOTE 18—RELATED PARTY AND DOW TRANSACTIONS

In conjunction with the Acquisition, the Company entered into certain agreements with Dow, including a five-year Master Outsourcing Services Agreement (“MOSA”) and certain Site and Operating Service Agreements. The MOSA provides for ongoing services from Dow in areas such as information technology, human resources, finance, environmental health and safety, training, supply chain and purchasing. Effective June 1, 2013, the Company entered into a Second Amended and Restated Master Outsourcing Services Agreement (“SAR MOSA”). The SAR MOSA replaces, modifies and extends the earlier MOSA, extending the term through December 31, 2020 and which automatically renews for two year periods unless either party provides six months’ notice of non-renewal to the other party. The services provided pursuant to the SAR MOSA generally are priced per function, and the Company has the ability to terminate the services or any portion thereof, for convenience any time after June 1, 2015, subject to payment of termination charges. Services which are “highly integrated” follow a different process for evaluation and termination. In addition, either party may terminate for cause, which includes a bankruptcy, liquidation or similar proceeding by the other party, for material breach which is not cured, or by Dow in the event of our failure to pay for the services thereunder. In the event of a change of control, as defined in the agreement, Dow has the right to terminate the SAR MOSA. As of December 31, 2015, the estimated minimum contractual obligations under the SAR MOSA are approximately$28.2 million.

In addition, the Company entered into certain Site and Operating Service Agreements. Under the Site Services Agreements (“SSAs”), Dow provides the Company utilities and other site services for Company-owned plants. Under the Operating Services agreements the Company provides services to Dow and receives payments for the operation of a Dow-owned plant. Similar to the above SAR MOSA, effective June 1, 2013, the Company entered into Second Amended and Restated Site Services Agreements (“SAR SSAs”). The SAR SSAs replace, modify and extend the original SSAs. These agreements generally have 25-year terms, with options to renew. These agreements may be terminated at any time by agreement of the parties, or, by either party, for cause, including a bankruptcy, liquidation or similar proceeding by the other party, or under certain circumstances for a material breach which is not cured. In addition, the Company may terminate for convenience any services that Dow has agreed to provide that are identified in any site services agreement as “terminable” with 12 months prior notice to Dow, dependent upon whether the service is highly integrated into Dow operations. Highly integrated services are agreed to be nonterminable. With respect to “nonterminable” services that Dow has agreed to provide to the Company, such as electricity and steam, the Company generally cannot terminate such services prior to the termination date unless the Company experiences a production unit shut down for which Dow is provided with 15-months prior notice, or upon payment of a shutdown fee. Upon expiration or termination, the Company would be obligated to pay a monthly fee to Dow, which obligation extends for a period of 45 (in the case of expiration) to 60 months (in the case of termination) following the respective event of each site services agreement. The agreements under which Dow receives services from the Company may be terminated under the same circumstances and conditions.

For the years ended December 31, 2015, 2014, and 2013, the Company incurred a total of $242.1 million, $282.5 million, and $303.2 million in expenses under these agreements, respectively, including $194.1 million, $233.7 million, and $235.1million, for both the variable and fixed cost components of the Site Service Agreements, respectively, and $48.0 million, $48.8 million, and $68.1 million covering all other agreements, respectively. The following tables detail these expenses by financial statement line item:

In connection with the Acquisition, certain of the Company’s affiliates entered into a latex joint venture option agreement (the “Latex JV Option Agreement”) with Dow, pursuant to which Dow was granted an irrevocable option to purchase 50% of the issued and outstanding interests in a joint venture to be formed by Dow and the Company’s affiliates with respect to the SB Latex business in Asia, Latin America, the Middle East, Africa, Eastern Europe, Russia and India. On May 30, 2014, the Company’s affiliates entered into an agreement with Dow to terminate the Latex JV Option Agreement, Dow’s rights to the option, and all other obligations thereunder, in exchange for a termination payment of $32.5 million. This termination payment was made on May 30, 2014, and the termination of the Latex JV Option Agreement became effective as of such date. This termination payment was recorded as an expense within “Other expense, net” in the consolidated statements of operations for the year ended December 31, 2014.

In addition, the Company has transactions in the normal course of business with Dow and its affiliates. For the years ended December 31, 2015, 2014, and 2013, sales to Dow and its affiliated companies were approximately $227.0 million, $343.8 million, and $294.7 million, respectively. For the years ended December 31, 2015, 2014, and 2013, purchases (including MOSA and SSA services) from Dow and its affiliated companies were approximately $1,244.2 million, $2,196.0 million, and $2,336.5 million, respectively.

As of December 31, 2015 and 2014, receivables from Dow and its affiliated companies were approximately $21.5 million and $18.7 million, respectively, and are included in “Accounts receivable, net of allowance” in the consolidated balance sheets. As of December 31, 2015 and 2014, payables to Dow and its affiliated companies were approximately $96.7 million and $156.9 million, respectively, and are included in “Accounts payable” in the consolidated balance sheet.

In connection with the Acquisition, the Company entered into the Advisory Agreement wherein Bain Capital provided management and consulting services and financial and other advisory services to the Company. The Advisory Agreement terminated upon consummation of the Company’s IPO in June 2014 and pursuant to the terms of the Advisory Agreement, the Company paid $23.3 million of termination fees representing acceleration of the advisory fees for the remainder of the original term. The termination fee was paid in June 2014 using the proceeds from the IPO, and was recorded as an expense within “Selling, general and administrative expenses” in the consolidated statement of operations for the year ended December 31, 2014. Bain Capital will continue to provide an immaterial level of ad hoc advisory services for the Company going forward. In conjunction with the above, we paid Bain Capital fees (including out-of-pocket expenses) of $0.1 million, $2.4 million, and $4.7million for the years ended December 31, 2015, 2014, and 2013, respectively (excluding the termination fees noted above).

Bain Capital also provides advice pursuant to a 10-year Transaction Services Agreement with fees payable equaling 1% of the transaction value of each financing, acquisition or similar transaction. In connection with the IPO, Bain Capital received $2.2 million of transaction fees, which were recorded within “Additional paid-in-capital” in the consolidated balance sheets as of December 31, 2014 (see Note 12). Bain Capital also received fees of approximately $13.9 million related to the issuance of the 2019 Senior Notes and the amendment to the 2018 Senior Secured Credit Facility in January 2013, which were included in the financing fees capitalized and included in “Deferred charges and other assets” in the consolidated balance sheet (see Note 10 for further discussion).

Total fees incurred from Bain Capital for these management and transaction advisory services were $0.1 million, $27.9 million, and $18.6 million, respectively, for the years ended December 31, 2015, 2014, and 2013.

Corporate unallocated includes corporate overhead costs, loss on extinguishment of long-term debt, and certain other income and expenses.

The primary measure of segment operating performance is EBITDA, which is defined as net income (loss) before interest, income taxes, depreciation and amortization. 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 the Company’s core operating performance. 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 EBITDA differently than the Company, and 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 the Company’s performance.

Asset and capital expenditure information is not reviewed or included with the Company’s internal management reporting. Therefore, the Company has not disclosed asset and capital expenditure information for each reportable segment.

The Company operates 34 manufacturing plants (which include a total of 80 production units) at 26 sites in 14 countries, inclusive of joint ventures and contract manufacturers. Sales are attributed to geographic areas based on the location where sales originated; long-lived assets are attributed to geographic areas based on asset location.

Restructuring

NOTE 20—RESTRUCTURING

Allyn’s Point Plant Shutdown

In September 2015, the Company approved the plan to close its Allyn’s Point latex manufacturing facility in Gales Ferry, Connecticut. This restructuring plan was a strategic business decision to improve the results of the overall Latex segment due to continuing declines in the coated paper industry in North America. Production at the facility ceased at the end of 2015, followed by decommissioning and demolition expected in 2016.

For the year ended December 31, 2015, the Company recorded restructuring charges of $6.7 million relating to the accelerated depreciation of the related assets at the Allyn’s Point facility and $0.4 million of employee termination benefit charges, which are included within “Selling, general and administrative expenses” in the consolidated statements of operations and were allocated entirely to the Latex segment.  These employee termination benefit charges remained accrued in “Accrued expenses and other current liabilities” in the consolidated balance sheet as of December 31, 2015.

The Company expects to incur approximately $0.3 million of incremental employee termination benefits charges during the first half of 2016 related to this restructuring, the majority which are expected to be paid by December 31, 2016.  Lastly, the Company expects to incur decommissioning and demolition costs associated with this plant shutdown in 2016, the cost of which will be expensed as incurred, within the Latex segment.  These costs cannot be reasonably estimated at this time.

Restructuring in Polycarbonate

During the second quarter of 2014, the Company announced a restructuring within its Basic Plastics & Feedstocks segment to exit the commodity market for polycarbonate in North America and to terminate existing arrangements with Dow regarding manufacturing services for the Company at Dow’s Freeport, Texas facility (the “Freeport facility”). The Company also entered into a new long-term supply contract with a third party to supply polycarbonate in North America. These revised arrangements became operational in the fourth quarter of 2014. In addition, the Company has executed revised supply contracts for certain raw materials that are processed at its polycarbonate manufacturing facility in Stade, Germany, which took effect January 1, 2015. These revised agreements are expected to facilitate improvements in future results of operations for the Basic Plastics & Feedstocks segment. Production at the Freeport facility ceased as of September 30, 2014, and decommissioning and demolition began thereafter, with completion in the first quarter of 2015.

For the year ended December 31, 2014, the Company recorded restructuring charges of $3.5 million relating to the accelerated depreciation of the related assets at the Freeport facility and $6.6 million in charges for the reimbursement of decommissioning and demolition costs incurred by Dow (of which $4.2 million remained accrued within “Accounts payable” on the consolidated balance sheet as of December 31, 2014). For the year ended December 31, 2015, the Company recorded the remainder of the restructuring charges of $0.5 million related to the reimbursement of decommissioning and demolition costs incurred by Dow. These charges were included in “Selling, general and administrative expenses” in the consolidated statements of operations, and were allocated entirely to the Basic Plastics & Feedstocks segment. There were no remaining amounts accrued in the consolidated balance sheet as of December 31, 2015.

Altona Plant Shutdown

In July 2013, the Company’s board of directors approved the plan to close the Company’s latex manufacturing facility in Altona, Australia. This restructuring plan was a strategic business decision to improve the results of the overall Latex segment. The facility manufactured SB latex used in the carpet and paper markets. Production at the facility ceased in the third quarter of 2013, followed by decommissioning, with demolition throughout most of 2014.

As a result of the plant closure, the Company recorded restructuring charges of $10.8 million for the year ended December 31, 2013. These charges consisted of property, plant and equipment and other asset impairment charges, employee termination benefit charges, contract termination charges, and incurred decommissioning charges.

For the year ended December 31, 2014, the Company recorded additional net restructuring charges of approximately $2.8 million, related primarily to incremental employee termination benefit charges, contract termination charges, and decommissioning costs. These charges were included in “Selling, general and administrative expenses” in the consolidated statements of operations, and were allocated entirely to the Latex segment. There were no additional restructuring charges recorded related to the Altona plant shutdown during the year ended December 31, 2015, and no amounts remained accrued as of December 31, 2015. Of the remaining balance as of December 31, 2014,  $1.2 million is recorded in “Accrued expenses and other current liabilities” and $0.9 million is recorded in “Other noncurrent liabilities” in the consolidated balance sheet.

The following tables provide a rollforward of the liability balances associated with the Altona plant shutdown for the years ended December 31, 2015 and 2014, respectively:

	Balance at						Balance at

Earnings (Loss) Per Share

NOTE 22—EARNINGS (LOSS) PER SHARE

Basic earnings (loss) per ordinary share (“basic EPS”) is computed by dividing net income (loss) available to ordinary shareholders by the weighted average number of the Company’s ordinary shares outstanding for the applicable period. Diluted earnings (loss) per ordinary share (“diluted EPS”) is calculated using net income (loss) available to ordinary shareholders divided by diluted weighted-average ordinary shares outstanding during each period, which includes unvested restricted shares. 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 EPS and diluted EPS for the years ended December 31, 2015, 2014, and 2013, respectively.

* Refer to Note 17 for discussion of restricted stock units granted in June 2014 to certain Company directors. As net loss was reported for the year ended December 31, 2014, potentially dilutive awards have not been included within the calculation of diluted EPS, as they would have an anti-dilutive effect.

Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

Basis of Presentation and Principles of Consolidation

The accompanying consolidated financial statements as of December 31, 2015 and 2014 and for each of the three years in the period ended December 31, 2015 are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The consolidated financial statements of the Company contain the accounts of all entities that are controlled and variable interest entities (“VIEs”) for which the Company is the primary beneficiary. A VIE is defined as a legal entity that has equity investors that do not have sufficient equity at risk for the entity to support its activities without additional subordinated financial support or, as a group, the holders of the equity at risk lack (i) the power to direct the entity’s activities or (ii) the obligation to absorb the expected losses or the right to receive the expected residual returns of the entity. A VIE is required to be consolidated by a company if that company is the primary beneficiary. Refer to Note 10 for further discussion of the Company’s accounts receivable securitization facility, which qualifies as a VIE and is consolidated within the Company’s financial statements.

All intercompany balances and transactions are eliminated. Joint ventures over which the Company has the ability to exercise significant influence that are not consolidated are accounted for by the equity method.

Use of Estimates in Financial Statement Preparation

Use of Estimates in Financial Statement Preparation

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual amounts could differ from these estimates.

Concentration of Credit Risk

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash equivalents and accounts receivables. The Company uses major financial institutions with high credit ratings to engage in transactions involving cash equivalents. The Company minimizes credit risk in its receivables by selling products to a diversified portfolio of customers in a variety of markets located throughout the world.

The Company performs ongoing evaluations of its customers’ credit and generally does not require collateral. The Company maintains an allowance for doubtful accounts for losses resulting from the inability of specific customers to meet their financial obligations, representing our best estimate of probable credit losses in existing trade accounts receivable. A specific reserve for doubtful receivables is recorded against the amount due from these customers. For all other customers, the Company recognizes reserves for doubtful receivables based on historical experience.

Financial Instruments

Financial Instruments

The carrying amounts of the Company’s financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and accrued and other current liabilities, approximate fair value due to their generally short maturities.

The estimated fair value of the Company’s 2021 Term Loan B, 2022 Senior Notes, and 2019 Senior Notes (all of which are defined in Note 10) are determined using level 2 inputs within the fair value hierarchy. Refer to Note 13 for the fair value of these debt instruments. When outstanding, the estimated fair values of borrowings under the Company’s 2020 Revolving Facility and Accounts Receivable Securitization Facility (both of which are defined in Note 10) are determined using level 2 inputs within the fair value hierarchy. The carrying amounts of borrowings under the 2020 Revolving Facility and Accounts Receivable Securitization Facility approximate fair value as these borrowings bear interest based on prevailing variable market rates.

At times, the Company manages its exposure to changes in foreign currency exchange rates, where possible, by entering into foreign exchange forward contracts. When outstanding, all derivatives, whether designated in hedging relationships or not, are required to be recorded on the balance sheet at fair value. The fair value of the derivatives is determined from sources independent of the Company, including the financial institutions which are party to the derivative instruments. The fair value of derivatives also considers the credit default risk of the paying party. If the derivative is designated as a fair value hedge, the changes in the fair value of the derivative and the hedged item will be recognized in earnings. If the derivative is designated as a cash flow hedge, the effective portion of the change in the fair value of the derivative will be recorded in other comprehensive income and will be recognized in the consolidated statements of operations when the hedged item affects earnings.

As of December 31, 2015 and 2014, the Company had certain foreign exchange forward contracts outstanding that were not designated for hedge accounting treatment. As such, the settlements and changes in fair value of underlying instruments are recognized in “Other expense, net” in the consolidated statements of operations. For the years ended December 31, 2015, 2014, and 2013, the Company recognized losses related to these forward contracts of $16.5 million, $28.2 million, and $0.6 million, respectively.

As of December 31, 2015, the Company also had foreign exchange forward contracts which are designated as cash flow hedges. As such, 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 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. No such contracts were outstanding as of December 31, 2014.

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. The Company records these foreign exchange forward contracts on a net basis, by counterparty within the consolidated balance sheets.

The Company presents the cash receipts and payments from hedging activities in the same category as the cash flows from the items subject to hedging relationships. As the items subject to economic hedging relationships are the Company’s operating assets and liabilities, the related cash flows are classified within operating activities in the consolidated statements of cash flows.

Foreign Currency Translation

Foreign Currency Translation

For the majority of the Company’s subsidiaries, the local currency has been identified as the functional currency. For remaining subsidiaries, the U.S. dollar has been identified as the functional currency due to the significant influence of the U.S. dollar on their operations. Gains and losses resulting from the translation of various functional currencies into U.S. dollars are not recorded within the consolidated statements of operations. Rather, they are recorded within the cumulative translation adjustment account as a separate component of shareholders’ equity (accumulated other comprehensive income) on the consolidated balance sheets. The Company translates asset and liability balances at exchange rates in effect at the end of the period and income and expense transactions at the average exchange rates in effect during the period. Gains and losses resulting from foreign currency transactions are recorded within the consolidated statements of operations.

For the year ended December 31, 2015 and 2014, the Company recognized net foreign exchange transaction gains of $6.1 million and $32.4 million, respectively. For the year ended December 31, 2013, the Company recognized net foreign exchange transaction losses of $18.3 million. These amounts exclude the impacts of foreign exchange forward contracts discussed above. Gains and losses on net foreign exchange transactions are recorded within “Other expense, net” in the consolidated statements of operations.

Environmental Matters

Environmental Matters

Accruals for environmental matters are recorded when it is considered probable that a liability has been incurred and the amount of the liability can be reasonably estimated, based on current law and existing technologies. These accruals are adjusted periodically as assessment and remediation efforts progress, or as additional technical or legal information become available. Accruals for environmental liabilities are recorded within “Other noncurrent obligations” in the consolidated balance sheets at undiscounted amounts. As of December 31, 2015 and 2014, there were no accruals for environmental liabilities recorded.

Environmental costs are capitalized if the costs extend the life of the property, increase its capacity, or mitigate or prevent contamination from future operations. Environmental costs are also capitalized in recognition of legal asset retirement obligations resulting from the acquisition, construction or normal operation of a long-lived asset. Any costs related to environmental contamination treatment and clean-ups are charged to expense. Estimated future incremental operations, maintenance and management costs directly related to remediation are accrued when such costs are probable and reasonably estimable.

Cash and Cash Equivalents

Cash and Cash Equivalents

Cash and cash equivalents generally include time deposits or highly liquid investments with original maturities of three months or less.

Inventories

Inventories

Inventories are stated at the lower of cost or market, with cost being determined on the first-in, first-out (“FIFO”) method. The Company periodically reviews its inventory for excess or obsolete inventory, and will write-down the excess or obsolete inventory value to its net realizable value, if applicable.

Property, Plant and Equipment

Property, Plant and Equipment

Property, plant and equipment are carried at cost less accumulated depreciation and less impairment, if applicable, and are depreciated over their estimated useful lives using the straight-line method. Capitalized costs associated with computer software for internal use are amortized on a straight-line basis over their estimated useful life.

Expenditures for maintenance and repairs are charged against income as incurred. Expenditures that significantly increase asset value, extend useful asset lives or adapt property to a new or different use are capitalized. These expenditures include planned major maintenance activity or turnaround activities that increase our manufacturing plants’ output and improve production efficiency as compared to pre-turnaround operations. As of December 31, 2015 and 2014, $7.6 million and $9.2 million, respectively, of the Company’s net costs related to turnaround activities were capitalized within “Deferred charges and other assets” in the consolidated balance sheets, and are being amortized over the period until the next scheduled turnaround.

The Company periodically evaluates actual experience to determine whether events and circumstances have occurred that may warrant revision of the estimated useful lives of property, plant and equipment. Engineering and other costs directly related to the construction of property, plant and equipment are capitalized as construction in progress until construction is complete and such property, plant and equipment is ready and available to perform its specifically assigned function. Upon retirement or other disposal, the asset cost and related accumulated depreciation are removed from the accounts and the net amount, less any proceeds, is charged or credited to income. The Company also capitalizes interest as a component of the cost of capital assets constructed for its own use.

Impairment and Disposal of Long-Lived Assets

Impairment and Disposal of Long-Lived Assets

The Company evaluates long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. When undiscounted future cash flows are not expected to be sufficient to recover an asset’s carrying amount, the asset is written down to its fair value based on a discounted cash flow analysis utilizing market participant assumptions.

Long-lived assets to be disposed of by sale are classified as held-for-sale and are reported at the lower of carrying amount or fair value less cost to sell, and depreciation is ceased. Long-lived assets to be disposed of in a manner other than by sale are classified as held-and-used until they are disposed.

Goodwill and Other Intangible Assets

Goodwill and Other Intangible Assets

The Company records goodwill when the purchase price of a business acquisition exceeds the estimated fair value of net identified tangible and intangible assets acquired. Goodwill is tested for impairment at the reporting unit level annually, or more frequently when events or changes in circumstances indicate that the fair value of a reporting unit has more likely than not declined below its carrying value. The Company utilizes a market approach and an income approach (under the discounted cash flow method) to calculate the fair value of its reporting units. The annual impairment assessment is completed using a measurement date of October 1st.  No goodwill impairment losses were recorded in the years ended December 31, 2015, 2014 and 2013.

Finite-lived intangible assets, such as our intellectual property and manufacturing capacity rights, are amortized on a straight-line basis and are reviewed for impairment or obsolescence if events or changes in circumstances indicate that their carrying amount may not be recoverable. If impaired, intangible assets are written down to fair value based on discounted cash flows. No intangible asset impairment losses were recorded in the years ended December 31, 2015, 2014 and 2013.

Deferred Financing Fees

Deferred Financing Fees

Capitalized fees and costs incurred in connection with the Company’s financing arrangements are recorded in “Deferred charges and other assets” within the consolidated balance sheets. For the 2021 Term Loan B and 2022 Senior Notes (and the 2019 Senior Notes, prior to their repayment in May 2015), deferred financing fees are amortized over the term of the agreement using the effective interest method, while for the 2020 Revolving Facility and the Accounts Receivable Securitization Facility, deferred financing fees are amortized using the straight-line method over the term of the respective facility. Amortization of deferred financing fees is recorded in “Interest expense, net” within the consolidated statements of operations.

Investments in Unconsolidated Affiliates

Investments in Unconsolidated Affiliates

Investments in unconsolidated affiliates in which the Company has the ability to exercise significant influence (generally, 20% to 50% owned companies) are accounted for using the equity method. Investments are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount of the investment may not be recoverable. An impairment loss is recorded whenever a decline in fair value of an investment in an unconsolidated affiliate below its carrying amount is determined to be other-than-temporary.

Sales

Sales

Sales are recognized when the revenue is realized or realizable and the earnings process is complete, which occurs when risk and title to the product transfers to the customer, typically at the time shipment is made. As such, title to the product generally passes when the product is delivered to the freight carrier. Standard terms of delivery are included in contracts of sale, order confirmation documents and invoices. Freight costs and any directly related costs of transporting finished product to customers are recorded as “Cost of sales” in the consolidated statements of operations. Taxes on sales are excluded from net sales.

Sales are recorded net of estimates for returns and price allowances, including discounts for prompt payment and volume-based incentives.

Cost of Sales

Cost of Sales

The Company classifies the costs of manufacturing and distributing its products as cost of sales. Manufacturing costs include raw materials, utilities, packaging and fixed manufacturing costs associated with production. Fixed manufacturing costs include such items as plant site operating costs and overhead, production planning, depreciation and amortization, repairs and maintenance, environmental, and engineering costs. Distribution costs include shipping and handling costs.

Selling, General and Administrative Expenses

Selling, General and Administrative Expenses

Selling, general and administrative (“SG&A”) expenses are charged to expense as incurred. SG&A expenses are the cost of services performed by the marketing and sales functions (including sales managers, field sellers, marketing research, marketing communications and promotion and advertising materials) and by administrative functions (including product management, R&D, business management, customer invoicing, and human resources). R&D expenses include the cost of services performed by the R&D function, including technical service and development, process research including pilot plant operations, and product development.

Total R&D costs included in SG&A expenses were approximately $51.9 million, $53.4 million and $49.7 million for the years ended December 31, 2015, 2014 and 2013, respectively.

The Company expenses promotional and advertising costs as incurred to SG&A expenses. Total promotional and advertising expenses were approximately $3.5 million, $2.9 million and $3.0 million for the years ended December 31, 2015, 2014 and 2013, respectively.

Pension and Postretirement Benefits Plans

Pension and Postretirement Benefits Plans

The Company has several defined benefit plans, under which participants earn a retirement benefit based upon a formula set forth in the plan. The Company also provides certain health care and life insurance benefits to retired employees mainly in the United States and Brazil. The plans provide health care benefits, including hospital, physicians’ services, drug and major medical expense coverage, and life insurance benefits.

Accounting for defined benefit pension plans and other postretirement benefit plans, and any curtailments and settlements thereof, requires various assumptions, including, but not limited to, discount rates, expected rates of return on plan assets and future compensation growth rates. The Company evaluates these assumptions at least once each year, or as facts and circumstances dictate, and makes changes as conditions warrant.

A settlement is a transaction that is an irrevocable action that relieves the employer (or the plan) of primary responsibility for a pension or postretirement benefit obligation, and that eliminates significant risks related to the obligation and the assets used to effect the settlement. When a settlement occurs, the Company does not record settlement gains or losses during interim periods when the cost of all settlements in a year is less than or equal to the sum of the service cost and interest cost components of net periodic pension cost for the plan in that year.

Income Taxes

Income Taxes

The provision for income taxes is determined using the asset and liability approach of accounting for income taxes. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from differences between the financial and tax basis of the Company’s assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. With the adoption of new guidance from the Financial Accounting Standards Board (“FASB”) as of December 31, 2015, for each tax jurisdiction in which the Company operates, deferred tax assets and liabilities are offset against one another and are presented as a single noncurrent amount within the consolidated balance sheets.  See “- Recent Accounting Guidance” below for further discussion of the impact of adopting this guidance.

Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. Provision has been made for income taxes on unremitted earnings of subsidiaries and affiliates, except for subsidiaries in which earnings are deemed to be indefinitely invested.

The Company recognizes the financial statement effects of uncertain income tax positions when it is more likely than not, based on the technical merits, that the position will be sustained upon examination. The Company accrues for other tax contingencies when it is probable that a liability to a taxing authority has been incurred and the amount of the contingency can be reasonably estimated. Interest accrued related to unrecognized tax and income tax related penalties are included in the provision for income taxes. The current portion of uncertain income taxes positions is recorded in “Income taxes payable” while the long-term portion is recorded in “Other noncurrent obligations” in the consolidated balance sheets.

Stock-based Compensation

Stock-based Compensation

Refer to Note 17 to the consolidated financial statements for detailed discussion regarding the Company’s stock-based compensation award programs.  The following provides a brief summary of the key accounting policy elections related to these awards.

On all awards, forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Stock-based compensation expense recognized in our consolidated financial statements is based on awards that are ultimately expected to vest.

Restricted Stock Awards issued by the Parent

From 2010 through 2013, our Parent granted various time-based and performance-based restricted stock awards to certain key members of management. Any related compensation associated with these awards is allocated to the Company from the Parent.

Stock-based compensation expense for these awards is measured at the grant date, based on the fair value of the award. Time-based and modified time-based restricted stock awards are generally recognized as expense on a graded vesting basis over the related service period. Prior to their modification in June 2014, the Company recognized compensation cost related to performance-based restricted stock awards if and when it was deemed probable that the related performance condition would be achieved. When applicable, the Company calculated the fair value of its performance-based restricted stock awards using a combination of a call option and digital option model.

2014 Omnibus Incentive Plan

In connection with the IPO, the Company’s board of directors approved the 2014 Omnibus Plan. Since that time, certain equity grants have been awarded, comprised of RSUs and options awards (defined in Note 17 to the consolidated financial statements).

Compensation costs for the RSUs are measured at the grant date based on the fair value of the award and are recognized ratably as expense over the applicable vesting term. The fair value of RSUs is equal to the fair market value of the Company’s ordinary shares based on the closing price on the date of grant.

Compensation cost for the option awards is measured at the grant date based on the fair value of the award and is recognized as expense over the appropriate service period utilizing graded vesting. The fair value for option awards is computed using the Black-Scholes pricing model, whose inputs and assumptions are determined as of the date of grant.

Recent Accounting Guidance

Recent Accounting Guidance

In April 2014, the FASB issued amendments to guidance for reporting discontinued operations and disposals of components of an entity. The amended guidance requires that a disposal representing a strategic shift that has (or will have) a major effect on an entity’s financial results or a business activity classified as held-for-sale should be reported as discontinued operations. The amendments also expand the disclosure requirements for discontinued operations and add new disclosures for individually significant dispositions that do not qualify as discontinued operations. The Company adopted this guidance effective January 1, 2015, and the adoption did not have a significant impact on the Company’s financial position, results of operations, or disclosures.

In May 2014, the FASB and the International Accounting Standards Board (“IASB”) jointly issued new 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. This guidance is effective for public entities for annual and interim periods beginning after December 15, 2017. The Company is currently assessing the impact of adopting this guidance on its financial statements and results of operations.

In January 2015, the FASB issued guidance to simplify income statement classification by removing the concept of extraordinary items from GAAP. The Company adopted this guidance effective January 1, 2015 and the adoption did not have an impact on the Company’s financial position or results of operations.

In April 2015, the FASB issued guidance that requires deferred financing fees related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying value of that debt liability, consistent with debt discounts. The recognition and measurement guidance for deferred financing fees are not affected. This new guidance, which is to be applied on a retrospective basis, is effective for public companies for annual and interim periods beginning after December 15, 2015, with early adoption permitted. The Company will adopt this guidance effective January 1, 2016.  As of December 31, 2015, the Company had $32.7 million of unamortized deferred financing fees classified as noncurrent assets within “Deferred charges and other assets” on the consolidated balance sheet, of which approximately $25.7 million will be reclassified as a reduction of “Long-term debt” on the consolidated balance sheet upon adoption.

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. This pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2016, and prospective adoption is required. The Company is currently assessing the impact of adopting this guidance on its financial position and results of operations.

In November 2015, the FASB issued guidance which requires that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. This guidance is effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods, and may be applied either prospectively or retrospectively, with early adoption permitted. The Company adopted this guidance effective December 31, 2015 on a prospective basis, noting that prior periods were not retrospectively adjusted. If the Company had retrospectively adopted this guidance, $11.8 million and $1.4 million of current deferred tax assets and liabilities, respectively, would have been reclassified, resulting in a total of $57.1 million and $27.2 million of noncurrent deferred tax assets and liabilities, respectively, on the consolidated balance sheet as of December 31, 2014.

(1) This amount represents settlement losses from one of the Company’s defined benefit plans in Switzerland due to the termination of certain employees during the year, which resulted in a loss recognized in the year ended December 31, 2014 due to a charge against the unamortized net loss recorded in other comprehensive income.

(2) This amount represents a curtailment loss from one of the Company’s defined benefit plans in Germany due to the reduction or cessation of benefit accruals for certain employees’ future services. The adjustment in the benefit obligation from the curtailment resulted in a loss recognized during the year ended December 31, 2013 due to a charge against the unamortized net loss recorded in other comprehensive income.

(3) This amount represents a curtailment gain from the Company’s other postretirement benefit plan in The Netherlands, due to the cessation of retiree medical benefit accruals effective January 1, 2015.

(4) This adjustment was made to the Company’s pension plan in The Netherlands to reflect the introduction of a salary cap and lower accrual rate on pension benefits as a result of tax law changes effective January 1, 2015. The impact of the change resulted in an adjustment to prior service credit in other comprehensive income as of December 31, 2014, which will be amortized to net periodic benefit cost over the estimated remaining service period of the employees.

(5) This is primarily related to the transfer of all remaining employees who were previously participants in the Dow Plans in Switzerland and The Netherlands to Company Successor Plans effective January 1, 2013, as discussed above.

(6) These amounts include the prior period net periodic cost and other comprehensive income components of the postretirement benefits in Brazil recognized during 2014, as discussed above.

(7) This amount is primarily related to a reduction in annuity conversion rates announced by the insurance provider for the pension plans in Switzerland. The impact of the change resulted in an adjustment to prior service credit in other comprehensive income as of December 31, 2015, which will be amortized to net periodic benefit cost over the estimated remaining service period of the employees.

(8) The amount represents an adjustment to the original purchase price allocation from the Acquisition as a portion of the postretirement benefits obligation recorded in Brazil was assumed from Dow.

(9) The fair values of certain plan assets as of December 31, 2015 and 2014 were determined using cash surrender values provided under the insurance contracts which took effect on January 1, 2013. The resulting change in the fair value of plan assets due to the use of cash surrender values was included as “return on plan assets”.
