D. Risk Factors

Risks Related to Our Business

Our ability to maintain our growth and profitability depend on the demand for photovoltaic products and the development of photovoltaic technologies, among other things.

The solar industry is at a relatively early stage of development, and the extent of acceptance of photovoltaic products is uncertain. The photovoltaic industry does not have data as far back as the semiconductor industry or other more established industries, for which trends can be assessed more reliably from data gathered over a longer period of time. Demand for photovoltaic products may not develop or may develop to a lesser extent than we anticipate. Many factors may affect the viability of widespread adoption of photovoltaic technology and demand for photovoltaic products, including:

In the event that photovoltaic technologies do not develop in a manner that increases the demand for polysilicon or demand for solar products does not expand as we expect, average selling prices may move downward as a result, and our future growth and profitability will be materially and adversely affected.

IncreasingThe imbalance between polysilicon prices may lead to some polysilicon manufacturers reentering the market, whichsupply and demand could cause polysilicon prices to decline and materially and adversely affect our profitability.

Our polysilicon sales prices are affected by a variety of factors, including global supply and demand conditions. Over the years, many polysilicon manufacturers have significantly increased their capacity to meet customer demand and continue to expand capacities in order to achieve economies of scale. However, the slow and uneven economic recovery from the global financial crisis as well as the significant decrease in global petroleum prices since their peak in mid-2008 have reduced or delayed the general demand for photovoltaic products. In late 2008 and 2009, newly available polysilicon supply and slowed global photovoltaic market growth resulted in an excess supply of polysilicon, which led to a significant decline in polysilicon prices. Although global photovoltaic demand recovered substantially from the second half of 2010 through the first half of 2011, the market price for polysilicon experienced another significant decline in the second half of 2011 due to excess supply and decreasing demand. In 2012, the market price for polysilicon continued to decline. As a result of the polysilicon supply and demand fluctuation, we reduced the selling price of our polysilicon and thus experienced a continued decrease in revenues derived from polysilicon in 2012. In 2013, global demand for polysilicon began to increase, and such trend continued into 2014.2015. Nevertheless, the average selling price of polysilicon in China was under pressure duringsince the fourth quarter of 2014 and through the whole year of 2015 due to rising volumepolysilicon supply both from overseas and domestic polysilicon manufacturers. In the first half of 2016, average selling prices of polysilicon importedwere relatively strong due to rush orders placed before China’s solar PV feed-in tariff adjustment went effective at the end of June 2016. In the second half of 2016, average selling prices of polysilicon declined due to decreasing demand. In 2017, we expect that there may be additional polysilicon supply capacities including those from overseas. As a result,new manufacturers. If the imbalance between polysilicon manufacturers with competitive cost structures benefited from the increase in sales pricessupply and global demand. If sales pricedemand continues to go up, some polysilicon manufacturers with less competitive cost structures may be able to reenter the market, whichexist, it could cause polysilicon prices to continue to decline and thus materially and adversely affect our profitability.

We may not be able to continue to receive the same level of support from Daqo Group Co., Ltd., or Daqo Group, a related party of ours, which may have a material adverse effect on our business and results of operations.

Since our inception, we have substantially benefited from financial support from Daqo Group, one of the largest electrical equipment manufacturers in China, and we expect to continue to benefit from Daqo Group in the foreseeable future. As of December 31, 2014,2016, we had amounts due to Daqo Group and its subsidiaries in the form of interest-free loans of $89.7$20.6 million, which are payable on demand. Please see “— We need a significant amount of cash to fund our future capital expenditure requirements and working capital needs; if we cannot obtain additional sources of liquidity when needed, our growth prospects and future profitability may be materially and adversely affected” below. In addition, Daqo Group has granted us a permanent and royalty-free license to use the “Daqo” brand, which is a well-recognized brand in the electrical industry in China. We have benefited from the strong brand recognition of “Daqo” in our business development efforts, as evidenced by our ability to secure major customers based in China within a short period after we commenced commercial production of polysilicon. Daqo Group has agreed in writing not to engage in the business of manufacturing, marketing or distributing polysilicon or any other solar power products anywhere in the world or compete in any manner with our businesses without our consent for an indefinite term. Daqo Group provides financial support to us to meet certain of our working capital requirements and obligations as they come due. However, we cannot assure you that we will continue to receive the same level of support, or any support at all, from Daqo Group in the future. If Daqo Group ceases to support us, our business, results of operations and prospects may be materially and adversely affected. In addition, any negative publicity associated with Daqo Group will likely have an adverse impact on our reputation, which could materially and adversely affect our business. In the event of any disagreements with Daqo Group, we may have to resort to legal proceedings in China to enforce our rights, which could be costly, time consuming and involve uncertain outcomes.

Historically we incurred substantial net losses in 2012 and 2013. Although we generated a profit in each fiscal year since 2014, we may experience future losses and may not be able to generate sufficient revenues in the future to sustain profitability.

As a result of the slump in the global demand for and sales price of polysilicon, we experienced a significant decrease in our revenues for our continuing operations in 2012 as compared to 2011 and incurred a net loss of $115.6 million in 2012. Despite improvements in our revenue in 2013 compared to 2012, in 2013 we still incurred a net loss of $221.1 million including $158.4 million of fixed-asset impairment loss, compared to $115.6 million including $42.8 million of fixed-asset impairment loss in 2012.

We had net income of $16.7 million in the year ended December 31, 2014 as a result of our continuous cost reduction efforts and increased global demand for and sales price of polysilicon, as well as a decrease in depreciation expenses of approximately $18.7 million. Since January 1, 2014, we revised the estimate of the expected useful lives of the machinery and equipment from 10 years to 15 years, and the buildings and structures from 20 years to 30 years, which reduced depreciation expenses by approximately $18.7 million. We had net income of $13.0 million and $43.9 million, in 2015 and 2016, respectively, as a result of our expanded capacities, growing sales volume and our continuous cost reduction efforts for both polysilicon and wafer manufacturing operations. Although we generated a profit in fiscal years 2014, 2015 and 2016, we may not be able to sustain profitability and our cash flows may be negative again in the future. Please see “— Our revenues and results of operations have fluctuated and are likely to fluctuate in the future” below.

We had a significant working capital deficit as of December 31, 2014.2016. Daqo Group provides financial support to us to meet certain of our working capital requirements and obligations as they become due. If we are not able to generate adequate operating cash flow or obtain adequate financial support from Daqo Group or from other sources, we will face the risk of not being able to continue as a going concern.

The challenging solar photovoltaic market situation in 2012 characterized by declining prices across the whole value chain has caused our polysilicon and wafer businesses to experience significant financial losses. Even though the industry started to recover slowly during 2013 and into 2014, we are unable to predict if the current upward trend will continue. As of December 31, 2014,2016, we had a working capital deficit (being our total consolidated current liabilities less our total consolidated current assets) of $274.1$176.4 million. In addition, we have made and expect tomay continue to make significant capital expenditures on our expansion project at our Xinjiang polysilicon facilities.

Our continuation as a going concern is dependent upon financial support from Daqo Group and our ability to continue to obtain other sources of financing. Daqo Group provides financial support to us to meet certain of our working capital requirements and obligations as they become due. As of December 31, 2014,2016, we had amounts due to Daqo Group and its subsidiaries in the form of interest-free loans of $89.7$20.6 million. On March 6, 2015,21, 2017, we obtained a letter of financial support from Daqo Group and certain of our other shareholders in which they have committed to provide us with sufficient funding to support our operations during the twelve months ending DecemberMarch 31, 2015.2018. Further, the letter of financial support provides that Daqo Group will not require us to pay the amounts that we owed to Daqo Group and three of its subsidiaries, Daqo Solar Co., Ltd, or Daqo Solar, Xinjiang Daqo Investment Co., Ltd., or Xinjiang Daqo Investment, and Daqo New Material, as of DecemberMarch 31, 2014,2018, before JanuaryApril 1, 2016.2018. In addition, DagoDaqo Group will provide us with funding to support us to repay all the financial obligations already committed related to the expansion project at our Xinjiang facilities and we are not required to repay such amounts before JanuaryApril 1, 2016. As a condition for obtaining2018. Meanwhile, we have committed to Daqo Group’s financial support,Group that we are required to immediately suspend thewill implement our expansion project atbased on our Xinjiang facilities if we do not have sufficientavailable financial resources to continue the project after we repay all other financial obligations as they become due in the twelve months ending December 31, 2015.resources. However, we can provide no assurances that Daqo Group and our shareholders will honor their undertakings under the letter of financial support. If the Daqo Group or its subsidiaries were to be unable to honor their undertakings under the letter of financial support or if the industry reverses its current upward trend in demand, we will face significant pressure on our working capital and we will face the risk of not being able to continue as a going concern.

Our consolidated financial statements do not reflect any adjustments relating to recoverability and classification of recorded assets or the amounts and classification of liabilities or any other adjustments that might be necessary should we be unable to continue as a going concern. Our inability to continue as a going concern would materially and adversely affect our financial condition, results of operations and business prospects.

The reduction in or elimination of government subsidies and economic incentives for solar energy applications could cause demand for our products and our revenues to decline.

When upfront system costs are factored into cost per kilowatt hour, the current cost of solar power still exceeds the cost of traditional forms of energy in many locations. As a result, national and local governmental authorities in many countries, including China, have provided subsidies and economic incentives in the form of feed-in tariffs, rebates, tax credits and other incentives to distributors, system integrators and manufacturers of photovoltaic products to promote the use of solar energy and to reduce dependency on other forms of energy. We believe that the near-term growth of the market for solar energy applications depends in large part on the availability and size of government subsidies and economic incentives. The reduction or elimination of government subsidies and economic incentives may hinder the growth of this market or result in increased price competition for solar energy products, which could cause our revenues to decline. These government subsidies and economic incentives could be reduced or eliminated altogether. For example, in 2010, Spain announced its plan to cut the subsidized electricity prices paid to new photovoltaic solar power plants by up to 45%, which significantly reduced installations of new solar energy projects in the country. In 2010, Germany introduced an approximately 24% to 26% solar feed-in tariffs reduction for rooftop systems and 20% to 25% reduction for ground-based systems. In early 2012, Germany further reduced its feed-in tariffs by 15% to up to 24.43 Euro cents per kilowatt hour for rooftop systems and up to 18.76 Euro cents per kilowatt hour for ground-based systems. On July 5, 2012, Italian officials published a ministerial decree which revised the system of incentives for the production of electricity from PV plants. Pursuant to the ministerial decree, the incentives for new PV plants will cease once the relevant total expenditure reaches EUR6.7 billion. In 2013, the German government announced plans to reduce the expansion of solar power after Germany added 7.5 gigawatts, or GW, and 7.6 GW of capacity in 2011 and 2012, respectively, to bring its total to 32.6 GW, which was nearly as much as the rest of the world combined. In 2014, the total solar PV installation in Germany was 1.9 GW, decreased from 3.3 GW in 2013. In addition, government financial support of photovoltaic products has been, and may continue to be, challenged on constitutional grounds and found unlawful in certain countries. The slowdown of the European and Chinese economy in 2013 and 2014 may continue to exert downward pressure on the amount of government subsidiaries for solar energy applications in these two regions. In 2014, although global solar PV installations increased by over 23.3% compared to 2013, the European markets shrank significantly in major markets like Germany, Italy and Spain. Furthermore,In 2015, global solar PV installations increased by approximately 27% to 57 GW, compared to 45 GW in 2014. Nevertheless, oil prices started to move downward indecline significantly since the second half of 2014.2014 and through the whole year of 2015. In 2016, global solar PV installations continued its growing trend and reached approximately 73 GW. However, oil prices still hover low, and there are industry reports indicating that the growth rate of global PV installations may slow down in 2017 and 2018. If the decrease in oil prices continues, government incentives provided to the solar industry in major markets may be reduced, which may result in a decrease in average selling prices of polysilicon. Reductions in, or elimination of, government subsidies and economic incentives for solar energy applications before the photovoltaic industry reaches the economies of scale necessary for solar power to become cost-effective in a non-subsidized market place could result in decreased demand for solar generation products and, as a result, for polysilicon, which could cause our revenues to decline.

Our limited operating history may not serve as an adequate basis to judge our future prospects and results of operations.

We have a limited operating history. We commenced polysilicon manufacturing in 2008 and wafer manufacturing in 2011. Several of our senior management and key employees have worked together at our company for only a relatively short period of time, and a number of our senior officers were promoted to their posts in October 2012. Our future success will depend on our ability to expand our manufacturing capacity significantly beyond its current level and further expand our customer base. To address these risks, we must, among other things, continue to respond to competition and volatile market developments, attract, retain and motivate qualified personnel, implement and successfully execute expansion plans and improve our technologies. We cannot assure you that we will be successful in addressing such risks.

Although we were profitable in 2011, we experienced significant decreases in revenue and incurred substantial net losses in 2012 and 2013. We had positive net income in 2014.2014, 2015 and 2016. However, our limited operating history makes the prediction of future results of operations difficult, and therefore, it is unclear if we could sustain revenue growth or profitability in the future. Our business model, technology and ability to achieve satisfactory manufacturing yields for polysilicon at higher volumes are unproven. Compared to companies with a long and well-established operating history and companies operating in less volatile sectors, our results of operations are more susceptible to the impact of adverse operating environment and supply and demand risks.

Our revenues and results of operations have fluctuated and are likely to fluctuate in the future.

Fluctuations of our revenues and results of operations may occur on a quarterly and on an annual basis and may be due to a number of factors, many of which are beyond our control. These factors include, among others, fluctuation in the global average selling prices of photovoltaic products, fluctuation in the volume of our products shipped, changes in end-user demand for the photovoltaic products manufactured and sold by us or our customers, the gain or loss of significant customers, the availability of governmental subsidies or financial support and changes in our electricity, natural gas, raw material or labor costs. For example, although our revenue has improved since 2013 and we have regained profitability in 2014, 2015 and 2016, our revenues and results of operations may worsen again if one or more of these factors become unfavorable to our business. Furthermore, wafers traditionally have had lower profit margins than polysilicon, and we may need to price aggressively to gain market share or remain competitive in this business, which may further reduce our net margins and cause our financial results to fluctuate from time to time.

Therefore, you should consider our future prospects in light of the risks and uncertainties experienced by early stage companies in a rapidly evolving and increasingly competitive market in China.

We need a significant amount of cash to fund our future capital expenditure requirements and working capital needs; if we cannot obtain additional sources of liquidity when needed, our growth prospects and future profitability may be materially and adversely affected.

We need a significant amount of cash to fund our operations. In particular, we will need substantial additional funding to finance our expansion project at our Xinjiang polysilicon facilities which includes relocating existing equipment fromand our Chongqing wafer facilities to meet our working capital requirements and to repay any short-term or long-term bank borrowings when due. We will also require cash resources to fund our research and development activities in order to remain competitive on cost and technology.

We have relied in the past and expect in the next 12 months to continue to rely mainly on operating cash flows, renewal and roll-over of our bank credit facilities and financial support from Daqo Group to finance our working capital and capital expenditures requirements. The photovoltaic markets remain competitive, and payment collection in the solar photovoltaic industry remains challenging. Any delay or failure in collecting amounts owed from customers will adversely affect our company’s cash flow situation. In addition, future acquisitions, expansions, market changes or other developments may cause us to require additional financing. We expect to incur additional debt in the future. Our ability to obtain external financing in the future is subject to a number of uncertainties, including:

If we are unable to obtain funding in a timely manner or on commercially acceptable terms, or at all, our growth prospects and ability to maintain profitability may be materially and adversely affected.

We may not be successful in our efforts to continue to manufacture polysilicon in a cost-effective manner.

The technology used to manufacture polysilicon is complex, requires costly equipment and is continuously being modified in an effort to improve yields and product performance. We may face significant challenges relating to polysilicon production in the future. Microscopic impurities such as dust and other contaminants, difficulties in the manufacturing process, disruptions in the supply of utilities or defects in the key materials or tools used to manufacture polysilicon could interrupt manufacturing, reduce yields or cause a portion of the polysilicon to be rejected by our customers, which would materially and adversely affect our profitability.

Our effective capacity and ability to produce high volumes of polysilicon depend on the cycle time for each batch of polysilicon. We may encounter problems in our manufacturing process or facilities as a result of, among other things, production failures, construction delays, human error, equipment malfunction or process contamination, all of which could seriously harm our operations. We are dependent on the availability of inexpensive electricity to keep our production costs down. We may experience production delays if any modifications we make in the manufacturing process to shorten production cycles are unsuccessful. Moreover, failure to achieve acceptable manufacturing levels may make our polysilicon costs uncompetitive, which could materially and adversely affect our business, financial condition and results of operations.

Further development in alternative polysilicon production technologies or other changes in the photovoltaic industry could render our production process too costly or obsolete, which could reduce our market share and cause our sales and profits to decline.

Although the vast majority of the polysilicon produced in the world utilizes the chemical vapor deposition process, or the “modified Siemens process,” several alternative production processes have been developed that may have significantly lower production costs. Compared with other polysilicon production processes, a disadvantage of the modified Siemens process is the large amount of electricity required. For example, REC, GCL and SMP currently operate or are constructing facilities that use the “fluidized bed reactor” method for producing polysilicon using saline (SiH4) as feed-in gas. Other polysilicon manufacturers are establishing facilities using upgraded metallurgical grade silicon process to produce solar-grade polysilicon. Moreover, some polysilicon manufacturers who are using “modified Siemens process” have adopted newer technologies such as Hydrochlorination, which could enable them to produce polysilicon in a more cost effective way compared to the traditional “modified Siemens process.”

Further developments in competing polysilicon production technologies may result in lower manufacturing costs or higher product performance than those achieved from the modified Siemens process, including the one we employ. We will need to invest significant financial resources in research and development to expand our market position, keep pace with technological advances in polysilicon production and effectively compete in the future. Failure to further refine our technology could make our production process too costly or obsolete, which could reduce our margins and market share, cause our revenues to decline and materially and adversely affect our results of operations.

Technological changes in the solar power industry could render our products uncompetitive or obsolete, which could reduce our market share and cause our sales and profits to decline.

The solar power industry is characterized by evolving technologies and standards. These technological evolutions and developments place increasing demands on the improvement of our products, such as polysilicon and wafers. Other companies may develop production technologies that enable them to produce silicon wafers of higher quality at a lower cost than our products. Technologies developed or adopted by others may prove more advantageous than ours for commercialization of solar power products and may render our products obsolete. As a result, we may need to invest significant resources in research and development to maintain our market position, keep pace with technological advances in the solar power industry, and effectively compete in the future. Our failure to further refine and enhance our products and processes or to keep pace with evolving technologies and industry standards could cause our products to become uncompetitive or obsolete, which could materially and adversely reduce our market share and affect our results of operations.

Alternative technologies in cell manufacturing may reduce the demand for polysilicon.

The vast majority of silicon-based photovoltaic cell manufacturers use chunk or granular polysilicon. However, alternative technologies have been commercialized. One such technology, thin-film cell production, uses little to no silicon in the production of solar cells. Thin-filmAlthough in general, thin-film solar cells are currently less costly to produce than silicon-based solar cells. Significant expansion of thin-film solar cell production has been announced which may put pressure on the entire value chain of silicon-based solar cell production. This expansion may in turn restrict the market fornot as competitive as silicon-based solar cells which would reducein terms of efficiency and cost, thin-film solar cells have their own dominating niche markets, for example, the demandmarkets for our polysilicon.the building integrated PV applications. If the demand for polysilicon is adversely affected by increased demand for, and improvements to, alternative technologies, our revenues and results of operations could be materially and adversely affected.

Our future commercial production and expansion project in Xinjiang, China may not be successful.

We finished construction of our Phase 2a2A polysilicon facilities in Shihezi, Xinjiang Uyghur Autonomous Region in September 2012 and successfully reached our targets in terms of capacity and cost structure by the end of the first quarter of 2013. We are in the processThe construction and installation of conducting our Phase 2b capacity2B expansion project at our Xinjiang polysilicon facilities, which is expected to bewas completed by the end ofduring the second quarter of 2015 and increaseachieved full production capacity in the third quarter of 2015, which increased our polysilicon annual capacity from 6,150 MT to 12,150 MT. In addition, we are considering further capacityJuly 2015, our board of directors approved our Phase 3A expansion project in Xinjiang. We completed the construction and installation of Phase 3A at our Xinjiang facilitiesthe end of 2016 and commenced initial production in the medium term, orfirst quarter of 2017. By the Phase 3 expansion. Subject to market and industry conditions,end of February 2017, we expect our Phase 3 expansion, which may be conducted in two stages, to further increase our total polysiliconachieved full production capacity to 25,000of 18,000 MT by early 2017. We are also in the process of upgrading our off-gas treatment process from traditional Hydrogenation technology to Hydrochlorination technology.per annum. Although the Xinjiang location provides many strategic advantages, including lower electricity costs, we face a number of uncertainties in relation with our future commercial production and expansion project in Xinjiang.

As part of our expansion project, we decided to relocate existing machinery and equipment in our polysilicon facilities in Chongqing, with total book value of $116.1$84.2 million as of December 31, 2013,2016, to our Xinjiang facilities. As of December 31, 2014,2016, we had relocated machinery and equipment of approximately $46.1$68.5 million in book value. After a comprehensive analysisIn 2015 and 2016, we incurred an impairment charge of the capacity$1.6 million and comparability of the$0.2 million, respectively, attributable to certain identified remaining assets in Chongqing that were not transferrable and could not be reutilized in our Xinjiang expansion project. With respect to our remaining machinery and equipment in Chongqing, if we concluded that it would be more efficientfail to usesuccessfully relocate, reinstall or reutilize the remaining machinery and equipment in Chongqing in our Phase 3 expansion, which is expected to fully ramp up by early 2017, as compared with using them in our Phase 2 project. If we fail to complete our Phase 3 expansion, or if we fail to successfully relocate, install or utilize the remaining machinery and equipment in the Phase 3 expansion,future potential expansions, we may incur significant impairment losses related to such remaining machinery and equipmentassets of approximately $70$15.7 million in book value, and our operating results and financial condition may be materially and adversely affected as a result.

In addition, there are many risks associated with our future production in Xinjiang, any of which could cause significant disruption to production, including:

One or more of these factors could harm our Xinjiang operations and consequently, could adversely affect our overall operating results.

Furthermore, under the letter of financial support we obtained from Daqo Group on March 6, 2015,21, 2017, we are required to immediately suspend the expansion project at our Xinjiang facilities if we do not have sufficient financial resources to continue the project after we repay all other financial obligations as they become due in the twelve months ending December 31, 2015.due. See “— We had a significant working capital deficit as of December 31, 2014.2016. Daqo Group provides financial support to us to meet certain of our working capital requirements and obligations as they become due. If we are not able to generate adequate operating cash flow or obtain adequate financial support from Daqo Group or from other sources, we will face the risk of not being able to continue as a going concern” above.

If we are unable to manage our expansion effectively, our business and financial results may be adversely affected.

InSince 2013, and 2014, we have experienced a period of growth and expansion in terms of revenueproduction capacity and production capacity.sales volume. We generated revenue of $86.9 million, $109.0 million and $182.6 million in 2012, 2013 and 2014, respectively. We ramped up ourachieved a nameplate capacity toof 6,150 MT in the first quarter of 2014. We are2014 and further ramped up our nameplate capacity to 12,150 MT in the processthird quarter of expanding2015. Our polysilicon production for 2016 reached a record high of 13,068 MT, which surpassed our polysilicon facilities in Xinjiang to increase our annualnameplate capacity of 12,150 MT per annum. In 2014, 2015 and 2016, we sold 5,972 MT, 8,234 MT and 10,883 MT, respectively, of polysilicon production(excluding internal sales to 12,150 MT.our in-house wafer facilities). We are also considering further capacity expansioncompleted the construction and installation of Phase 3A at the Xinjiang facilitiesend of 2016 and commenced initial production of the Phase 3A project in the medium term to expand total polysiliconfirst quarter of 2017 and have achieved full production capacity to 25,000 MT by early 2017.capacity. To accommodate our continued expansion, we anticipate that we will need to implement a variety of new and upgraded operational and financial systems, procedures and controls, including the improvement of our accounting and other internal management systems, all of which require substantial management efforts. We also will need to continue to expand, train, manage and motivate our workforce and manage our customer relationships. All of these endeavors will require substantial management efforts and skill and require significant additional expenditures. We cannot assure you that we will be able to manage our growth effectively, and any failure to do so may have a material adverse effect on our business and financial results. Moreover, even if we do expand our polysilicon manufacturing capacity and our wafer business as planned, we may be unable to generate sufficient customer demand for our photovoltaic products to support our increased production levels or successfully integrate our polysilicon and wafer manufacturing businesses to achieve operational efficiency, which could adversely affect our business and results of operations.

Our future success depends substantially on our ability to significantly expand our polysilicon production capacity and output, and to relocate equipment to our Xinjiang facilities, which exposes us to a number of risks and uncertainties.

Our future success depends on our ability to significantly increase both polysilicon production capacity and output, and to relocate equipment to our Xinjiang facilities. If we fail to do so, we may not be able to benefit from economies of scale to reduce our costs per kilogram of polysilicon, to maintain our competitive position or to improve our profitability. Further, our expansion plans are dependent on the successful installation of the equipment we are relocating to our Xinjiang facilities. Our ability to establish additional production capacity and increase output is subject to significant risks and uncertainties, including:

We operate in an increasingly competitive market, and we may not be able to compete successfully with competitors who have greater resources than us.

The photovoltaic market is expected to become increasingly competitive. Our competitors include international polysilicon and wafer manufacturers, such as Hemlock, Wacker, OCI, REC, MEMC and Chinese domestic polysilicon and wafer manufacturers, such as GCL-Poly, TBEA,Xinte Energy Co., Ltd., Asia Silicon Co., Ltd., China Silicon Corporation Sichuan Xinguang Silicon Science and Technology, LDK Solar, ReneSola.Yongxiang Co., Ltd. There are also likely new entrants into the polysilicon manufacturing market in China, such as Xinjiang East Hope New Energy Ltd. and the joint venture formed by REC and Shanxi Youser. In addition, some solar cell and module manufacturers, including some of our existing and potential customers may have the intention of establishing polysilicon production or affiliate relationships with manufacturers of polysilicon. We compete with these in-house capabilities, which could limit our ability to expand our sales or even reduce our sales to our existing customers. Many of our competitors have substantially greater financial, technical, manufacturing and other resources than we do. Our competitors’ greater size and longer operating history provide them with a competitive advantage with respect to manufacturing costs because of their economies of scale and their ability to purchase raw materials at lower prices. Our competitors may have stronger relationships or may enter into exclusive relationships with some of our key customers. As a result, they may be able to respond more quickly to changing customer demands or to devote greater resources to the development, promotion and sales of polysilicon than we can. Failure to adapt to changing market conditions and to compete successfully with existing or new competitors may materially and adversely affect our financial condition and results of operations.

We depend on a limited number of customers and sales contracts for a significant portion of our revenues, and the loss of any customer or cancellation of any contract may cause significant fluctuations or declines in our revenues.

In 2012, 20132014, 2015 and 2014,2016, our top three customers in aggregate accounted for approximately 40.9%32.1%, 38.5%40.5% and 32.1%37.1% of our total revenues, respectively. We anticipate that our dependence on a limited number of customers will continue for the foreseeable future. Consequently, any one of the following events may cause material fluctuations or declines in our revenues:

Polysilicon production is energy-intensive, and if our energy costs rise or if our electricity and other utility supplies are disrupted, our results of operations will be materially and adversely affected.

The polysilicon production process, particularly the modified Siemens process that we use, is highly dependent on a constant supply of electricity and other utilities, such as steam, natural gas and water, to maintain the optimal conditions for polysilicon production. If electricity or other utility supplies are not maintained at the desired level, we may experience significant delays in the production of polysilicon. In the past, there were shortages in electricity supply in various regions across China, especially during peak seasons, such as in the summer. In addition, the uncommonly cold weather in China in the winter of 2010 resulted in a surge in natural gas demand, which in turn caused severe gas shortages in many regions, including Chongqing, where one of our polysilicon manufacturing sites is located. The local governmental authorities in the worst-hit areas took measures to reduce or restrict the amount of natural gas supplied to non-residential users. We primarily use natural gas for our in-house steam production and steam is critical for our manufacturing process. Although the natural gas shortage did not directly affect our operations, if shortages become more severe in the future, our natural gas supply may be reduced or suspended, which would significantly disrupt our manufacturing process. In addition to shortages, we are subject to potential risks of interruptions in energy supply due to power outages, equipment failure, weather conditions or other causes which could force us to cease production for a prolonged period of time. In the event that electricity or other utility supplies to our manufacturing facilities are disrupted, our business, results of operations and financial condition could be materially and adversely affected. Even if we have access to sufficient sources of electricity and other utilities, any significant increase in the costs of utilities could adversely affect our profitability, as we consume substantial amounts of electricity and other utilities in our manufacturing process. If electricity and other utility costs were to rise, our results of operations could be materially and adversely affected.

Our current indebtedness could adversely affect our business, financial condition and results of operations.

As of December 31, 2014,2016, we had outstanding long-term bank borrowings, of $146.7 million, including current portion of long-term borrowings of $69.4$162.3 million with a weighted average interest rate of 6.9%,5.8% and outstanding short-term bank borrowings of $90.4$55.6 million with a weighted average interest rate of 6.8%5.0%, and we expect to incur additional debt in the future. We borrowed the majority of these bank loans from Bank of China and China ConstructionChongqing Rural Commercial Bank with guarantees from Daqo Group. We cannot assure you that we will be able to renew these borrowings when they become due or to obtain other loans or credits from other banks or other lenders on terms satisfactory to us or at all to satisfy the substantial capital expenditure requirements associated with our capacity expansion, whether on our own or with the continuing support from Daqo Group. In addition, the indebtedness could have an adverse effect on our future operations, including, among other things: (1) reducing the availability of our cash flow to fund our working capital, capital expenditures or other general corporate purposes as a result of interest or principal payments; (2) subjecting us to the risk of interest rate increases on our indebtedness which bears floating interest rates; and (3) placing us at a competitive disadvantage compared to our competitors that have less debt or are otherwise less leveraged. Any of these factors could have a material and adverse effect on our business, financial condition and results of operations.

We face risks and uncertainties expanding our business through alliances, joint ventures or acquisitions.

We may in the future, if presented with appropriate opportunities, acquire or invest in technologies, businesses or assets that are strategically important to our business or form alliances with key players in the photovoltaic industry to further expand our business. Such acquisitions and investments could expose us to potential risks, including risks associated with the assimilation of new operations, technologies and personnel, unforeseen or hidden liabilities, the inability to generate sufficient revenues to offset the costs and expenses of acquisitions, and potential loss of, or harm to, our relationships with employees, customers and suppliers as a result of integration of new businesses. Investments in new businesses may also divert our cash flow from servicing our debts and making necessary capital expenditures. In addition, we may incur impairment losses on our acquisitions and investments in equity securities. The diversion of our management’s attention and any difficulties encountered with respect to the acquisitions, investments or alliances or in the process of integration could have an adverse effect on our ability to manage our business. Furthermore, our experience in the polysilicon manufacturing industry may not be as relevant or applicable in downstream markets. We may also face intense competition from companies with greater experience or established presence in the targeted downstream markets or competition from our industry peers with similar expansion plans. Any failure to integrate any acquired businesses or joint ventures into our operations successfully and any material liabilities or potential liabilities of any acquired businesses or joint ventures that are not identified by us during our due diligence process for such acquisitions or investments could materially and adversely affect our business and financial condition.

If we are unable to operate effectively or operational disruptions occur, our business, results of operations and financial condition could be adversely affected.

Production of polysilicon requires the use of volatile materials and chemical reactions sensitive to temperature and pressure and requires the use of external controls to maintain safety. For example, in the production of polysilicon, we use trichlorosilane, or TCS, which is a highly combustible substance if brought into contact with moisture in the air and is therefore potentially destructive and extremely dangerous if mishandled or used in uncontrolled circumstances. The occurrence of a catastrophic event involving TCS as a result of a natural disaster or human error at one of our polysilicon production facilities could threaten, disrupt or destroy a significant portion or all of our polysilicon production capacity at such facilities for a significant period of time. Additionally, the smooth operation of our polysilicon production facilities depends significantly on our ability to maintain temperatures and pressure at appropriate levels, the supply of steam at a consistent pressure level, the availability of adequate electricity and our ability to control the application of such electricity. Accordingly, mistakes in operating our equipment or an interruption in the supply of electricity or steam at our production facilities could result in the production of substandard polysilicon or substantial shortfalls in production and could reduce our production capacity for a significant period of time. In addition, we voluntarily shut down our manufacturing facilities from time to time on an as-needed basis for maintenance and quality check purposes. For example, in September 2012, we halted production at the Phase 1 polysilicon facilities for maintenance and technology improvement projects, which lasted until we decided to relocate the equipment at this facility to Xinjiang in the second quarter of 2013. In April 2013, we temporarily shut down our Phase 2 facilities in Xinjiang for periodic maintenance and technology improvements. In April 2014, we temporarily shut down our Phase 2 facilities in Xinjiang for periodic maintenance and preparation for the Phase 2 Hydrochlorination project. In May 2015, we conducted annual maintenance of the Xinjiang polysilicon facilities, which affected our polysilicon production for five days. In October 2016, we conducted annual maintenance and several technology improvement projects in our Xinjiang polysilicon facilities, and concurrently completed interconnections between our new and existing facilities in Xinjiang. The annual maintenance, construction, installation of new equipment and interconnection of facilities affected our polysilicon production for approximately three weeks. These abovementioned shutdowns have reduced and may further reduce the volume and increase the cost of polysilicon we produce. In addition, we may need to use hazardous equipment for our wafer manufacturing process. Such equipment requires skill and experience for safe operation. We could experience events such as equipment failures, explosions or fires due to employee errors, equipment malfunctions, accidents, and interruptions in electricity or water cooling supplies, natural disasters or other causes. In addition, such events could cause damage to properties, personal injuries or even deaths. As a result, we may in the future experience production curtailments or shutdowns or periods of reduced production. The occurrence of any such events or disruptions could result in loss of revenues and could also damage our reputation, any of which could have a material adverse effect on our business, operating results and financial condition.

Our operations are subject to natural disasters, adverse weather conditions, operating hazards, environmental incidents and labor disputes.

We may experience earthquakes, floods, mudslides, snowstorms, typhoon, power outages, labor disputes or similar events beyond our control that would affect our operations. Our manufacturing processes involve the use of hazardous equipment, including, but not limited to, furnaces, squaring machines and wire saws. We also use, store and generate volatile and otherwise dangerous chemicals and waste during our manufacturing processes, which are potentially destructive and dangerous if not properly handled or in the event of uncontrollable or catastrophic circumstances, including operating hazards, fires and explosions, natural disasters, adverse weather conditions and major equipment failures.

In addition, our polysilicon and wafer production and storage facilities are located in either Chongqing or Xinjiang, China. The occurrence of any natural disaster, unanticipated catastrophic event or unexpected accident in these locations could result in production curtailments, shutdowns or periods of reduced production, which could significantly disrupt our business operations, cause us to incur additional costs and affect our ability to deliver our products to our customers as scheduled, which may adversely affect our business, financial condition and results of operations. Moreover, such events could result in severe damage to property, personal injuries, fatalities, regulatory enforcement proceedings or in our being named as a defendant in lawsuits asserting claims for large amounts of damages, which in turn could lead to significant liabilities.

Occurrences of natural disasters, as well as accidents and incidents of adverse weather in or around either Chongqing or Xinjiang, China in the future may result in significant property damage, electricity shortages, disruption of our operations, work stoppages, civil unrest, personal injuries and, in severe cases, fatalities. Such incidents may result in damage to our reputation or cause us to lose all or a portion of our production capacity, and future revenue anticipated to be derived from the relevant facilities, any of which could have a material adverse effect on our business, operating results and financial condition.

Existing regulations and changes to these regulations may present technical, regulatory, economic and trade barriers to the purchase and use of photovoltaic products, which may significantly reduce demand for our products.

Photovoltaic products are subject to national and local regulations relating to building codes, safety, environmental protection, utility interconnection and metering and other aspects of the electric utility industry. In a number of countries, including China, these regulations are being modified and may continue to be modified. The purchases of, or further investment in the research and development of, alternative energy sources, including photovoltaic technology, could be deterred by unfavorable regulations, which could result in a significant reduction in the potential demand for our products. For example, without a regulatory mandated exception for solar power systems, electric utility companies are often charged interconnection or standby fees for putting distributed power generation on the electric utility grid. These fees could increase the cost to end users of using photovoltaic products and make them less desirable. In addition, trade authorities in foreign countries may apply trade sanctions against photovoltaic product imports from China, if the foreign trade authorities determine that the export sales from China are in violation of fair trade practices. Such trade sanctions can result in significant additional duties, which willmay adversely affect our photovoltaic product demand, thereby harming our business, prospects, results of operations and financial condition.

We obtain certain production equipment from a limited number of suppliers, and if such equipment is not delivered on time, is damaged in shipment or is otherwise unavailable, our ability to deliver polysilicon on time will suffer, which in turn could result in cancellation of orders and loss of revenues.

Our operations and expansion plans depend on our ability to obtain a sufficient amount of equipment that meets our specifications on a timely basis. Some of our equipment used in polysilicon and wafer production is not readily available from alternative vendors and would be difficult to repair or replace if it were to become damaged or cease working. If any of these suppliers were to experience financial difficulties or go out of business, or if there were any damage to or a breakdown of our production equipment, our business would incur losses. In addition, a supplier’s failure to supply our ordered equipment in a timely manner, with adequate quality and on terms acceptable to us, could delay the capacity expansion of our manufacturing facilities and otherwise disrupt our production schedule or increase our costs of production. We have experienced significant delays in the delivery of our key equipment in the past. Failure to obtain equipment meeting our specifications could have a material adverse effect on our business, financial condition and results of operations. Furthermore, demand for polysilicon and wafer production equipment may result in significant increases in prices of such equipment or shortages in related components for our intended expansion. Any unexpected price increases could materially and adversely affect our financial condition and results of operations.

We have sourced and will continue to source some of our production equipment from Chinese manufacturers, and we cannot assure you that the China-sourced equipment will perform at the same level as our imported equipment or will meet our quality requirements.

We have purchased key equipment from Chinese and international suppliers. Compared to major international suppliers, our China-based suppliers generally have shorter operating histories and less experience in providing equipment for the polysilicon industry. We cannot assure you that the locally made equipment will perform at similar levels of quality and reliability as our imported equipment. In the event the China-sourced equipment does not perform as well as the imported equipment or does not perform at all, we may encounter disruption in our manufacture or deterioration of product quality, which in turn could materially and adversely affect our business, financial condition and results of operations.

Product defects could result in increased costs, decreased sales, and damage to our customer relationships and our reputation.

Our photovoltaic products may contain defects that are not detected until after it is shipped or processed by our customers. In the event our products are returned to us due to product defects, we would be required to replace the defective products promptly. If we deliver products with defects, or if there is a perception that our products are of substandard quality, we may incur substantially increased costs associated with termination of contracts and replacement of shipped products, and our credibility, market reputation and relationship with customers will be harmed and sales of our products may be materially and adversely affected.

Substantially all of our production, storage, administrative, and research and development facilities are located in either Chongqing or Xinjiang, China. Any damage or disruption at these facilities would have a material adverse effect on our financial condition and results of operations.

Substantially all of our production, storage, administrative, and research and development facilities are currently located in either Chongqing or Xinjiang, China. Natural disasters, such as fire, floods, typhoons, earthquakes, snow storms, or other unanticipated catastrophic events, including power interruption, telecommunications failures, equipment failures, explosions, break-ins, terrorist acts or war, could significantly disrupt our ability to manufacture our products and operate our business. If any of our production facilities or material equipment were to experience any significant damage or downtime, we would not be able to meet our production targets and our business would incur losses. Any damage or disruption at these facilities would have a material adverse effect on our business, financial condition and results of operations.

We rely on third party intellectual property for certain key aspects of our operations, which subjects us to the payment of license fees and potential disruption or delays in the production of our products.

While we continue to develop and pursue patent protection for our own technologies, we expect to continue to rely on third party license arrangements for certain key aspects of our operations. For instance, we license from third party Hydrochlorination process technology for our polysilicon production. See “Item 4. Information on the Company — B. Business Overview — Intellectual Property” for details of the contractual arrangements. The fees associated with such licenses could adversely affect our financial condition and operating results. If for any reason we are unable to license necessary technology on acceptable terms or at all, it may become necessary for us to develop alternative technology internally, which could be costly and delay or disrupt our production and therefore have a material adverse effect on our business and operating results.

Failure to protect our intellectual property rights may undermine our competitive position, and litigation to protect our intellectual property rights may be costly.

We rely primarily on trade secrets and other contractual restrictions to protect our intellectual property. Contractual arrangements, such as the confidentiality and non-competition agreements and terms between us and our research and development personnel, afford only limited protection and the actions we may take to protect our trade secrets and other intellectual property may not be adequate. In addition, we currently hold 25 patents and have 15 pending patent applications in China covering various aspects of the polysilicon and wafer manufacturing processes. However, we cannot assure you that our patent applications will be eventually issued with sufficiently broad coverage to protect our technology and products. Failure to protect our intellectual property and proprietary rights may undermine our competitive position. Third parties may infringe on or misappropriate our proprietary technologies or other intellectual property and proprietary rights and use them to compete against us, which could have a material adverse effect on our business, financial condition or operating results.

Policing unauthorized use of proprietary technology can be difficult and expensive. In particular, the laws and enforcement procedures of China and certain other countries are uncertain or do not protect intellectual property rights to the same extent as the laws and enforcement procedures of the United States do. See “— Risks Related to Doing Business in China — Uncertainties in the interpretation and enforcement of Chinese laws and regulations could limit the legal protection available to you and us” below. We may need to resort to court proceedings to enforce our intellectual property rights in the future. Litigation relating to our intellectual property might result in substantial costs and diversion of resources and management attention away from our business. An adverse determination in any such litigation will impair our intellectual property and proprietary rights and may harm our business, prospects and reputation.

We may be exposed to infringement or misappropriation claims by third parties, which, if determined adversely to us, could cause us to pay significant damage awards.

Although we are currently strengthening our research and development capability, to date, substantially all of the intellectual property used in our production process was developed by third parties. Our success will be jeopardized if we cannot use and develop our technology and know-how without infringing the intellectual property rights of third parties. The validity and scope of claims relating to photovoltaic technology patents involve complex scientific, legal and factual questions and analysis and, therefore, may be highly uncertain. We may be subject to litigation involving claims of patent infringement or violation of other intellectual property rights of third parties. The defense and prosecution of intellectual property suits, patent opposition proceedings, and related legal and administrative proceedings can be both costly and time-consuming and may significantly divert the efforts and resources of our technical and management personnel. An adverse determination in any such litigation or proceedings to which we may become a party could subject us to significant liability to third parties, require us to seek licenses from third parties, to pay ongoing royalties, or to redesign our manufacturing process or our products or subject us to injunctions prohibiting the manufacture and sale of our products or the use of our technologies. Protracted litigation could also result in our customers or potential customers deferring or limiting their purchase or use of our products until resolution of such litigation.

Our business depends substantially on the continuing efforts of our executive officers and key employees, and our business may be severely disrupted if we lose their services.

Our future success depends substantially on the continued services of our executive officers and key employees, especially Mr. Guangfu Xu, our chairman, and Dr. Gongda Yao, our chief executive officer. If one or more of our executive officers or key employees were unable or unwilling to continue in their present positions, we might not be able to replace them easily, in a timely manner, or at all. Our business may be severely disrupted, our financial conditions and results of operations may be materially and adversely affected and we may incur additional expenses to recruit, train and retain personnel. If any of our executive officers or key employees join a competitor or form a competing company, we may lose customers, suppliers, know-how and key professionals and staff members. Each of our executive officers and key employees has entered into an employment agreement with us, which contains non-competition provisions. However, if any dispute arises between our executive officers and us, these agreements may not be enforceable in China, where these executive officers reside, in light of uncertainties with China’s legal system. See “— Risks Related to Doing Business in China — Uncertainties in the interpretation and enforcement of Chinese laws and regulations could limit the legal protection available to you and us” below.

Certain of our principal shareholders have substantial influence over our company and their interests may not be aligned with the interests of our other shareholders.

As of the date of this annual report, Messrs. Guangfu Xu, Xiang Xu and Dafeng Shi, our directors that are affiliated with Daqo Group, beneficially ownedown a total of 88,677,27592,031,442 or 33.3%35.2% of our ordinary shares, including shares that they had the right to acquire within 60 days. As a result of their high level of shareholding, these shareholders have substantial influence over our business, including decisions regarding mergers, consolidations and the sale of all or substantially all of our assets, election of directors and other significant corporate actions. These shareholders may take actions that are not in the best interest of us or our other shareholders. This concentration of ownership may discourage, delay or prevent a change in control of our company, which could deprive our other shareholders of an opportunity to receive a premium for their shares as part of a sale of our company and might reduce the price of our ADSs. These actions may be taken even if they are opposed by our other shareholders. These shareholders’ interests as beneficial owners of Daqo Group may not always be aligned with their interests as our shareholders. Should any conflict of interest arise, these shareholders may take actions not in the best interest of us and our other shareholders.

If we are unable to attract, train and retain qualified personnel, our business may be materially and adversely affected.

Our future success depends, to a significant extent, on our ability to attract, train and retain qualified personnel, particularly technical personnel with expertise in the photovoltaic industry. Since our industry is characterized by high demand and intense competition for talent, there can be no assurance that we will be able to attract or retain qualified technical staff or other highly skilled employees that we will need to achieve our strategic objectives. As we have a limited operating history and are in a stage of rapid growth, despite recent setbacks, our ability to train and integrate new employees into our operations may not meet the growing demands of our business. If we are unable to attract and retain qualified personnel, our business may be materially and adversely affected.

Compliance with environmental regulations can be expensive, and non-compliance with these regulations may result in adverse publicity and potentially significant monetary damages and fines.

As our manufacturing processes generate waste water and gas and other industrial wastes, we are required to comply with all applicable regulations regarding protection of the environment. We are in compliance with present environmental protection requirements and have all the necessary environmental permits to conduct our business in all material respects. However, if more stringent regulations are adopted in the future, the cost of compliance with these new regulations could be substantial. If we fail to comply with present or future environmental regulations, we may be required to pay substantial fines, suspend production or cease operations, which in turn would have a material adverse effect on our financial condition and results of operations.

The discontinuation of any of the preferential tax treatments or the financial incentives and grants currently available to us in China could adversely affect our overall results of operations.

Various Chinese governmental authorities have provided tax incentives to our subsidiaries in China. These incentives include income tax exemption or reduced enterprise income tax rates. For example, under the PRC Enterprise Income Tax Law, or the EIT Law, the statutory enterprise income tax rate is 25%. However, our Chinese subsidiary, Chongqing Daqo New Energy Co., Ltd., or Chongqing Daqo, as a “Chongqing Municipality High and New Technology Enterprise,” is entitled to a preferential enterprise income tax rate of 15%. The status is valid until December 2015November 2018 and can be renewed for additional three-year terms upon Chongqing Daqo’s application and the government’s approval. On November 25, 2014, Xinjiang Daqo New Energy Co., Ltd., or Xinjiang Daqo, our another Chinese subsidiary of ours, obtained a High and New Technology Enterprise, or HNTE, certificate for a valid period of 3 years till 2016. During the year ended December 31, 2014,2016, Xinjiang Daqo was entitled to a preferential tax rate of 15% because of its HNTE status. If there are significant changes in the business operations, manufacturing technologies or other criteria that cause the enterprise to no longer meet the criteria as a “high and new technology enterprise,” such status will be terminated from the year of such change. We cannot assure you that Chongqing Daqo or Xinjiang Daqo will continue to qualify as a “high and new technology enterprise” in future periods. Any increase in the enterprise income tax rate applicable to our Chinese subsidiaries or discontinuation or reduction of any of the preferential tax treatments or financial incentives currently enjoyed by our subsidiaries in China could adversely affect our business, operating results and financial condition.

The dividends we receive from our Chinese subsidiaries and our global income may be subject to Chinese tax under the EIT Law, which would have a material adverse effect on our results of operations; our foreign ADS holders may be subject to a Chinese withholding tax upon the dividends payable by us and Chinese tax on gains realized upon the sale or other disposition of our ADSs if we are classified as a Chinese “resident enterprise.”

Under the Chinese enterprise income tax laws and regulations, dividends, interests, rent, royalties and gains on transfers of property payable by a foreign-invested enterprise in China to its foreign investor who is a non-resident enterprise will be subject to a 10% withholding tax, unless such non-resident enterprise’s jurisdiction of incorporation has a tax treaty with China that provides for a reduced rate of withholding tax and such non-resident enterprise is the beneficial owner of the dividends, interests, rent, royalties and gain on transfers of property. The Cayman Islands, where Daqo Cayman is incorporated, does not have such a tax treaty with China.

Under the EIT Law, an enterprise established outside China with its “de facto management body” within China is considered a “resident enterprise” in China and will be subject to the Chinese enterprise income tax at the rate of 25% on its worldwide income. In April 2009, the Chinese State Administration of Taxation issued a circular to clarify criteria for determining the “resident enterprise” status of foreign companies which are controlled by PRC enterprises or PRC enterprise groups. Pursuant to the circular, to determine whether a company formed outside of mainland China and controlled by PRC enterprises or PRC enterprise groups incorporated in China should be treated as a Chinese resident enterprise, the tax authority will review factors such as the routine operation of the organizational body that effectively manages the enterprise’s production and business operations, locations of personnel holding decision-making power, location of finance and accounting functions and properties of the enterprise, and whether more than half of the directors or senior management personnel reside in China. Substantially all of our management members are based in China. However, it remains unclear how PRC tax authorities will classify an overseas company such as ours, which is controlled by PRC natural persons rather than PRC enterprises. If the Chinese tax authorities subsequently determine that Daqo Cayman should be classified as a resident enterprise, then our worldwide income will be subject to Chinese income tax, which may have a material adverse effect on our financial condition and results of operations. Notwithstanding the foregoing provision, the EIT Law also provides that, if a resident enterprise directly invests in another resident enterprise, the dividends received by the investing resident enterprise from the invested enterprise are exempted from income tax, subject to certain conditions. Therefore, if Daqo Cayman is classified as resident enterprise under the EIT Law, the dividends received from our Chinese subsidiaries may be exempted from withholding tax.

Moreover, if DagoDaqo Cayman is classified as a “resident enterprise” in China, non-resident enterprise ADS holders may be subject to a 10% withholding tax (20% in the case of non-PRC individual ADS holders) upon dividends payable by us and 10% tax on gains realized upon the sale or other disposition of our ADSs (20% in the case of non-PRC individual ADS holders). Any such tax may reduce the returns on your investment in our ADSs.

We have limited insurance coverage. In particular, we do not have any product liability insurance or business interruption insurance.

As the insurance industry in China is still in an early stage of development, the product liability insurance and business interruption insurance available in China offer limited coverage compared to that offered in many other countries. We do not have any product liability insurance or business interruption insurance. Any business disruption or natural disaster could result in substantial costs and a diversion of resources, which would have a material adverse effect on our business and results of operations.

As with other photovoltaic product manufacturers, we are exposed to risks associated with product liability claims if the use of our photovoltaic products results in injury. Since our polysilicon products are made into electricity generating devices, it is possible that users could be injured or killed by devices that use our products as a result of product malfunctions, defects, improper installation or other causes. We only began commercial shipment of our photovoltaic products in July 2008 and, because of our limited operating history, we cannot predict whether product liability claims will be brought against us in the future or the effect of any resulting negative publicity on our business. The successful assertion of product liability claims against us could result in potentially significant monetary damages and require us to make significant payments.

We have granted, and may continue to grant, stock options and other share-based compensation in the future, which may materially impact our future results of operations.

We adopted our 2009 share incentive plan, or the 2009 Plan, and our 2014 share incentive plan, or the 2014 Plan, in August 2009 and December 2014, respectively, that permit the grant of stock options, restricted shares and restricted share units to employees, directors and consultants of our company. Under the 2009 Plan and the 2014 Plan, we may issue awards to purchase up to 15,000,000 and 21,000,000 ordinary shares, respectively. As of the date of this annual report, excluding expired or cancelled options, we have granted options to purchase a total of 20,210,19119,189,566 of our ordinary shares and 12,653,992 restricted share units under these plans. In addition, we modified the exercise prices for certain outstanding options in January 2012, April 2013, January 2015 and JanuarySeptember 2015 in order to provide additional incentives to our employees and directors pursuant to an express authorization under our share incentive plan, allowing our board of directors to approve a downward adjustment of the option exercise prices without our shareholders’ approval. As a result of these option grants, option re-pricings and potential future grants under the plans, we have incurred, and will incur in future periods, significant share-based compensation expenses. We account for compensation costs for all stock options using a fair-value based method and recognize expenses in our consolidated statement of income in accordance with the relevant rules in accordance with U.S. GAAP, which may have a material adverse effect on our net income. Moreover, the additional expenses associated with share-based compensation may reduce the attractiveness of such incentive plans to us. However, if we limit the scope of our share incentive plans, we may not be able to attract or retain key personnel who expect to be compensated with incentive shares or options.

Risks Related to Doing Business in China

Uncertainties in the global economy and the slowdown of the Chinese economy may adversely affect our business, results of operations and financial condition.

The global financial markets experienced significant disruptions in 2008 and the United States, Europe and other economies went into recession. The recovery from the lows of 2008 and 2009 was uneven and is facing new challenges, including the escalation of the European sovereign debt crisis since 2011 and the slowdown of the Chinese economy in the recent years. It is unclear whether the European sovereign debt crisis will be contained and whether the rate of growth of the Chinese economy will continue slowing down. There is considerable uncertainty over the long-term effects of the expansionary monetary and fiscal policies that have been adopted by the central banks and financial authorities of some of the world’s leading economies, including China’s. There have also been concerns over unrest in the Middle East and Africa, which have resulted in volatility in oil and other markets, and over the possibility of a war involving Iran. There have also been concerns about the economic effect of the territorial disputes involving China in Asia and the tensions in the relationship between China and Japan. Economic conditions in China are sensitive to global economic conditions. Any prolonged slowdown in the global or Chinese economy may have a negative impact on our business, results of operations and financial condition, and continued turbulence in the international markets may adversely affect our ability to access the capital markets to meet liquidity needs.

Since we derive substantially all of our revenues from customers in China, any prolonged slowdown in the Chinese economy may have a negative impact on our business, results of operations and financial condition in a number of ways. For example, our customers may reduce or delay spending with us, while we may have difficulty expanding our customer base fast enough, or at all, to offset the impact of decreased spending by our existing customers. In addition, to the extent we offer credit to any customer and such customer experiences financial difficulties due to the economic slowdown, we could have difficulty collecting payment from such customer.

Changes in China’s economic, political or social conditions or government policies could have a material adverse effect on our business and operations.

Substantially all of our assets are located in and substantially all of our revenues are currently sourced from China. Accordingly, our business, financial condition, results of operations and prospects may be influenced to a significant degree by political, economic and social conditions in China generally and by continued economic growth in China as a whole.

The Chinese economy differs from the economies of most developed countries in many respects, including the level of government involvement, level of development, growth rate, control of foreign exchange and allocation of resources. Although the Chinese government has implemented measures since the late 1970s emphasizing the utilization of market forces for economic reform, the reduction of state ownership of productive assets and the establishment of improved corporate governance in business enterprises, a substantial portion of productive assets in China is still owned by the Chinese government. In addition, the Chinese government continues to play a significant role in regulating industry development by imposing industrial policies. The Chinese government also exercises significant control over the Chinese economic growth through the allocation of resources, controlling payment of foreign currency-denominated obligations, setting monetary policy and providing preferential treatment to particular industries or companies.

While the Chinese economy has experienced significant growth over the past decades, growth has been uneven, both geographically and among various sectors of the economy. The Chinese government has implemented various measures to encourage economic growth and guide the allocation of resources. Some of these measures benefit the overall Chinese economy, but may also have a negative effect on us. For example, our operating results and financial condition may be adversely affected by government control over capital investments or changes in tax regulations that are applicable to us, and by government policies or guidance aimed at curtailing the perceived over-capacity of certain industry sectors, such as polysilicon, steel, concrete and wind power equipment. See “Item 4. Information on the Company — B. Business Overview — Regulation — Renewable Energy Law and Other Government Directives.” The Chinese government has implemented certain measures, including interest rate increases, to control the pace of economic growth. These measures may cause decreased economic activity in China, which could in turn reduce the demand for our products and materially and adversely affect our operating results and financial condition.

Uncertainties in the global economy and the Chinese economy may adversely affect our business, results of operations and financial condition.

The global financial markets experienced significant disruptions in 2008 and the United States, Europe and other economies went into recession. The recovery from the lows of 2008 and 2009 was uneven and is facing new challenges, including the escalation of the European sovereign debt crisis since 2011 and the slowdown of the Chinese economy in 2012 and 2013. It is unclear whether the European sovereign debt crisis will be contained and whether the Chinese economy will resume its high growth rate. There is considerable uncertainty over the long-term effects of the expansionary monetary and fiscal policies that have been adopted by the central banks and financial authorities of some of the world’s leading economies, including China’s. There have also been concerns over unrest in the Middle East and Africa, which have resulted in volatility in oil and other markets, and over the possibility of a war involving Iran.

In addition, to the extent we offer credit to any customer and such customer experiences financial difficulties due to the economic slowdown, we could have difficulty collecting payment from such customer.

Uncertainties in the interpretation and enforcement of Chinese laws and regulations could limit the legal protection available to you and us.

The Chinese legal system is a civil law system based on written statutes. Unlike common law systems, it is a system in which legal decisions have limited value as precedents. In the late 1970s, the Chinese government began to promulgate a comprehensive system of laws and regulations governing economic matters in general. The overall effect of legislation and rule-making over the past three decades has been to significantly increase the protections afforded to various forms of foreign or private-sector investment in China. Our Chinese operating subsidiary, Chongqing Daqo, is a foreign-invested enterprise and is subject to laws and regulations applicable to foreign-invested enterprises as well as various Chinese laws and regulations generally applicable to companies in China. Our business is also subject to various industry policy, safety and environmental laws and regulations that affect our operations and production facility expansion plans, including those related to investment, project construction, building, zoning, fire prevention and work safety. These laws and regulations are still evolving, and their interpretation and enforcement involve uncertainties. In addition, due to the inconsistent regulatory enforcements in China, local Chinese governmental authorities have significant discretion in interpreting and implementing rules and regulations, and there is no assurance that the central government authorities will always agree with the interpretations and implementations of the local governmental authorities. Currently, we possess all material local governmental approvals relating to our operations and production capacity expansion plans. However, if a central government agency requires us to obtain its approval and if we fail to obtain such approval in a timely manner, or at all, we may be subject to the imposition of fines against us, or the suspension or cessation of our production capacity expansion plans. See “Item 4. Information on the Company — B. Business Overview — Regulation — Renewable Energy Law and Other Government Directives.” It may be more difficult to evaluate the outcome of any regulatory or legal proceedings and the level of legal protection we enjoy than in more developed legal systems. These uncertainties may impede our ability to continue our operations or planned capacity expansions, which, as a result, could materially and adversely affect our business and operations.

Chinese regulations relating to offshore investment activities by Chinese residents may increase the administrative burden we face and may subject our Chinese resident beneficial owners or employees to personal liabilities, limit our subsidiaries’ ability to increase its registered capital or distribute profits to us, limit our ability to inject capital into our Chinese subsidiaries, or may otherwise expose us to liability under Chinese law.

The State Administration of Foreign Exchange, or SAFE, has promulgated regulations that require Chinese residents and Chinese corporate entities to register with local branches of SAFE in connection with their direct or indirect offshore investment activities. These regulations may apply to our shareholders who are Chinese residents and may apply to any offshore acquisitions that we make in the future.

SAFE promulgated the Circular on Relevant Issues Concerning Foreign Exchange Control on Relating to Domestic Resident’s Offshore Investment and Financing and Roundtrip Investment through Special Purpose Vehicles, or SAFE Circular 37, in July 2014 that requires PRC residents or entities to register with SAFE or its local branch in connection with their establishment or control of any special purpose vehicles established for the purpose of overseas investment or financing. In addition, such PRC residents or entities must update their SAFE registrations when the offshore special purpose vehicle undergoes material events relating to any change of basic information (including change of such PRC citizens or residents, name and operation term), increases or decreases in investment amount, transfers or exchanges of shares, or mergers or divisions.

SAFE Circular 37 is issued to replace the Notice on Relevant Issues Concerning Foreign Exchange Administration for PRC Residents Engaging in Financing and Roundtrip Investments via Overseas Special Purpose Vehicles, or SAFE Circular 75.

If a Chinese shareholder with a direct or indirect stake in an offshore parent company fails to make the required SAFE registration, the Chinese subsidiaries of such offshore parent company may be prohibited from making distributions of profit to the offshore parent and from paying the offshore parent proceeds from any reduction in capital, share transfer or liquidation in respect of the Chinese subsidiaries, and the offshore parent company may also be prohibited from injecting additional capital into its Chinese subsidiaries. Furthermore, failure to comply with the SAFE registration requirement described above may result in liability for the Chinese shareholders and the Chinese subsidiaries under Chinese law for foreign exchange registration evasion.

We have, up to the present, completed SAFE registration for all current beneficial shareholders of our company who are, to our knowledge, Chinese residents. However, we may not be fully informed of the identities of the beneficial owners of our company and we cannot assure you that all of our Chinese resident beneficial owners will comply with SAFE regulations. The failure of our beneficial owners who are Chinese residents to make any required registrations may subject us to fines and legal sanctions, and prevent us from making distributions or paying dividends, as a result of which our business operations and our ability to distribute profits to you could be materially and adversely affected.

Participants of our share incentive plan who are PRC individuals are required to register with SAFE, and the failure to so comply could subject us and such participants to penalties.

In February 2012, SAFE promulgated the Notice on the Administration of Foreign Exchange Matters for Domestic Individuals Participating in the Stock Incentive Plans of Overseas Listed Companies, or the Stock Option Notice. According to the Stock Option Notice, a PRC domestic qualified agent or the PRC subsidiary of such overseas listed company must file an application with SAFE or its local counterpart on behalf of PRC resident individuals who participate in stock incentive plans of overseas publicly listed companies to obtain approval for an annual allowance with respect to the purchase of foreign exchange in connection with the stock holding or share option exercises. Our company is an “overseas publicly listed company,” and therefore, we and participants of our share incentive plan who are PRC individuals are subject to these regulations.

We have completed registration for options and restricted share units granted as of the date of this annual report. For future option and restricted share unit grants, if our application is unsuccessful or our option plan participants who are PRC individuals fail to work with us to complete the registration, we or such persons may be subject to fines and legal sanctions. Any failure to comply with such regulations may subject us and the relevant participants of our share incentive plan to fines and legal sanctions and prevent us from being able to grant share incentives to our personnel, as a result of which our business operations may be adversely affected.

Chinese regulation of direct investment and loans by offshore holding companies to Chinese entities may delay or limit us from making additional capital contributions or loans to our Chinese subsidiaries.

Any capital contributions or loans that we, as an offshore entity, make to our Chinese subsidiaries are subject to Chinese regulations. For example, for each of our Chinese subsidiaries, the aggregate amount of our loans to the Chinese subsidiary cannot exceed product of the difference between the amount of its total investment and its registered capital as approved by the foreign investment regulatory authorities under relevant Chinese laws, and the ratio of the paid-in capital to the committed registered capital, and the loans must be registered with the local branch of SAFE. For each foreign invested enterprise, such as Chongqing Daqo, when the Chinese foreign investment regulatory authorities approve the establishment of such foreign invested enterprise, the authorities approve the amounts of such enterprise’s registered capital, which represent the investors’ capital commitment in equity, and the amounts of its total investment, which represent the sum of its registered capital plus the amounts of its permitted loans. After the establishment of the foreign invested enterprise, the investors can seek regulatory approval to increase its registered capital and the total investment amounts, and upon approval, there will be increases in both amounts. There is a specific statutory guideline relating to the ratio of a foreign invested enterprise’s registered capital amount over total investment amount, and all foreign investment regulatory authorities in China must follow the ratio guideline when exercising their approval authority. However, there is no uniform statutory guideline applicable to all regulatory authorities regarding whether to approve the establishment of a new foreign invested enterprise or to approve any increase in the registered capital and total investment of an existing foreign invested enterprise. In practice, authorities consider factors such as overall governmental policies relating to the specific industry and demands in a particular industry and the approval usually takes one to three months depending on the locations of the foreign invested enterprises. The approved total investment amounts of Chongqing Daqo and Xinjiang Daqo are $286.0 million and $298.0$300.6 million, respectively. The registered capital of Chongqing Daqo is $96.0 million of which $69.6 million was contributed by Daqo Cayman as the sole investor. The registered capital of Xinjiang Daqo is $100.0$100.3 million, of which $93.1$99.3 million was contributed by Daqo Cayman as the sole investor.and $1.0 million was contributed by Xinjiang Daqo Investment Co., Ltd., an PRC entity that is a wholly-owned subsidiary of Daqo Group. As a result, the maximum permissible amounts that Chongqing Daqo and Xinjiang Daqo may borrow from Daqo Cayman are $137.8$190.0 million and $76.0$200.3 million, respectively. We may not make loans to Chongqing Daqo or Xinjiang Daqo in excess of the maximum amounts permissible unless we obtain government approval to increase their total investment amounts. In addition, any increases of our capital contributions to our Chinese subsidiaries beyond the previously authorized amount must be approved by the MOFCOM and the NDRC or their respective local counterparts. We cannot assure you that we will be able to obtain these approvals on a timely basis, or at all. If we fail to obtain such approvals, our ability to make equity contributions or provide loans to our Chinese subsidiaries or to fund their operations may be negatively affected, which could adversely affect our Chinese subsidiaries’ liquidity and their ability to fund their working capital and expansion projects and meet their obligations and commitments.

We rely principally on dividends and other distributions on equity paid by our wholly owned operating subsidiaries to fund any cash and financing requirements we may have, and any limitation on the ability of our operating subsidiaries to pay dividends to us could have a material adverse effect on our ability to borrow money or pay dividends.

As a holding company, we rely principally on dividends and other distributions on equity paid by our Chinese subsidiaries for our cash requirements, including funds necessary to service any debt we may incur. If our Chinese subsidiaries incur debt on their own behalf in the future, the instruments governing the debt may restrict their ability to pay dividends or make other distributions to us. Furthermore, relevant Chinese laws and regulations permit payments of dividends by Chinese subsidiaries only out of their retained earnings, if any, determined in accordance with Chinese accounting standards and regulations. Under Chinese laws and regulations, each of our Chinese subsidiaries is required to set aside a portion of its net income each year to fund a statutory surplus reserve until such reserve reaches 50% of its registered capital. This reserve is not distributable as dividends. As a result, our Chinese subsidiaries are restricted in their ability to transfer a portion of their net assets to us in the form of dividends, loans or advances. Limitation on the ability of our Chinese subsidiaries to pay dividends to us could materially and adversely limit our ability to borrow money outside of China or pay dividends to holders of our ADSs. See“—See “— Risks Related to Our Business — The dividends we receive from our Chinese subsidiaries and our global income may be subject to Chinese tax under the EIT Law, which would have a material adverse effect on our results of operations; our foreign ADS holders may be subject to a Chinese withholding tax upon the dividends payable by us and Chinese tax on gains realized upon the sale or other disposition of our ADSs if we are classified as a Chinese ‘resident enterprise.’”

Fluctuations in exchange rates could result in foreign currency exchange losses.

The conversionvalue of the RMB intoagainst the U.S. dollar and other currencies is affected by changes in China’s political and economic conditions and by China’s foreign currencies, including U.S. dollars, is based on rates set byexchange policies, among other things. In July 2005, the People’s Bank of China. The PRC government allowedchanged its decades-old policy of pegging the value of the RMB to appreciate bythe U.S. dollar, and the RMB appreciated more than 20% against the U.S. dollar between July 2005 and July 2008.over the following three years. Between July 2008 and June 2010, this appreciation halted and the exchange rate between the RMB and the U.S. dollar remained within a narrow band. Since June 2010, the PRC governmentRMB has allowed the RMB to appreciate slowlyfluctuated against the U.S. dollar, again, though there have been periods when the U.S. dollar has appreciated against the Renminbi as well. In March 2014, the People’s Bank of China widened the band around which the value of the Renminbi is allowed to deviate from the daily reference rate, which may allow for greater volatility in the U.S. dollarat times significantly and Renminbi exchange rate.unpredictably. It is difficult to predict how market forces or PRC or U.S. government policy may impact the exchange rate between the RMB and the U.S. dollar in the future.

AnyThe financial records of our PRC subsidiaries are maintained in Renminbi, which is their functional currency. We are therefore exposed to fluctuations in the exchange rate between the U.S. dollar and Renminbi. We do not currently hedge, and have not historically hedged, our operational exposure to this foreign currency fluctuation. Our consolidated financial results are presented in U.S. dollars, and therefore, during times of a strengthening U.S. dollar versus Renminbi, our reported revenue and earnings that are denominated in Renminbi will be reduced because the Renminbi will translate into fewer U.S. dollars. In addition, assets and liabilities are translated at the exchange rates at the balance sheet date. Equity accounts are translated at historical exchange rates. Revenues, expenses, gains and losses are translated at average rate of exchange prevailing during the periods presented. Translation adjustments arising from the use of differing exchange rates from period to period are recorded as cumulative translation adjustments and are shown as a separate component of other comprehensive income in our statement of changes in equity and comprehensive income. Accordingly, changes in currency exchange rates will cause our revenues, expenses, gains and losses, shareholders’ equity, and comprehensive income to fluctuate, and such fluctuations may have an adverse effect on our financial condition and results of operations.

Furthermore, any significant depreciation of the Renminbi against the U.S. dollar may have a material adverse effect on the value of, and any dividends payable on, our ADSs and ordinary shares. If we decide to convert our Renminbi into U.S. dollars for the purpose of making payments for dividends on our ordinary shares or for other business purposes, depreciation of the Renminbi against the U.S. dollar would reduce the U.S. dollar amount available to us. On the other hand, to the extent that we need to convert U.S. dollars into Renminbi for our operations, appreciation of the Renminbi against the U.S. dollar would have an adverse effect on the RMB amount we receive from the conversion. In addition, the value of your investment in our ADSs will be affected by the exchange rate between U.S. dollar and Renminbi because the value of our business is effectively denominated in Renminbi, while the ADSs will be traded in U.S. dollars. Fluctuation in the value of the Renminbi in either direction could have a material adverse effect on the value of our company and the value of your investment.

Failure to maintain effective internal control over financial reporting could have a material and adverse effect on the trading price of our ADSs.

We are subject to the reporting obligations under the U.S. securities laws. In connection with the audit of our internal controls over financial reporting as of and for the year ended December 31, 2011, we and our independent registered public accounting firm identified three “material weaknesses” including (i) our lack of accounting resources and expertise necessary to comply with U.S. GAAP and the Securities and Exchange Commission, or the SEC, financial reporting and disclosure requirements, (ii) our lack of sufficient resources to perform thorough reviews of consolidated financial statements and related footnote disclosures during the period-end financial reporting and disclosure process, and (iii) our lack of sufficient processes, documentation and approval of related party transactions with affiliates. In 2012, we have made enhancements to our internal controls over financial reporting. Based on these actions taken and our testing and evaluation of the effectiveness of our internal controls, we have concluded the material weaknesses no longer existed as of December 31, 2012, December 31, 2013, December 31, 2014, December 31, 2015 and December 31, 2014.2016. As of December 31, 2014,2016, our management concluded thatour internal control over financial reporting was effective. Our independent registered public accounting firm did not conduct an audit of our internal control over financial reporting for the years ended December 31, 2012 and 2013. For the yearyears ended December 31, 2014, 2015 and 2016, our independent registered public accounting firm performed an audit of our internal control over financial reporting.

However, we cannot assure you that we will maintain effective internal control over financial reporting on an ongoing basis. If we fail to maintain effective internal controls over financial reporting, we will not be able to conclude and our independent registered public accounting firm will not be able to report (if it is required to report) that we have effective internal controls over financial reporting in accordance with the Sarbanes-Oxley Act of 2002 in our future annual report on Form 20-F covering the fiscal year in which this failure occurs. Effective internal control over financial reporting is necessary for us to produce reliable financial reports. Any failure to maintain effective internal controls over financial reporting could result in the loss of investor confidence in the reliability of our financial statements, which in turn could have a material and adverse effect on the trading price of our ADSs. Furthermore, we may need to incur additional costs and use additional management and other resources as our business and operations further expand or in an effort to remediate any significant control deficiencies that may be identified in the future.

Proceedings instituted by the SEC against five PRC-based accounting firms, including our independent registered public accounting firm, could result in financial statements being determined to not be in compliance with the requirements of the Exchange Act.

Starting in 2011 the Chinese affiliates of the ‘‘big four’’ accounting firms, including our independent registered public accounting firm, were affected by a conflict between U.S. and Chinese law. Specifically, for certain U.S.-listed companies operating and audited in mainland China, the SEC and the Public Company Accounting Oversight Board, or the PCAOB, sought to obtain from the Chinese firms access to their audit work papers and related documents. The firms were, however, advised and directed that under Chinese law, they could not respond directly to the US regulators on those requests, and that requests by foreign regulators for access to such papers in China had to be channeled through the China Securities Regulatory Commission, or the CSRC.

In late 2012 this impasse led the SEC to commence administrative proceedings under Rule 102(e) of its Rules of Practice and also under the Sarbanes-Oxley Act of 2002 against the Chinese accounting firms, including our independent registered public accounting firm. A first instance trial of the proceedings in July 2013 in the SEC’s internal administrative court resulted in an adverse judgment against the firms. The administrative law judge proposed penalties on the firms including a temporary suspension of their right to practice before the SEC, although that proposed penalty did not take effect pending review by the Commissioners of the SEC. On February 6, 2015, before a review by the Commissioner had taken place, the firms reached a settlement with the SEC. Under the settlement, the SEC accepts that future requests by the SEC for the production of documents will normally be made to the CSRC. The firms will receive matching Section 106 requests, and are required to abide by a detailed set of procedures with respect to such requests, which in substance require them to facilitate production via the CSRC. If they fail to meet specified criteria, the SEC retains authority to impose a variety of additional remedial measures on the firms depending on the nature of the failure. Remedies for any future noncompliance could include, as appropriate, an automatic six-month bar on a single firm’s performance of certain audit work, commencement of a new proceeding against a firm, or in extreme cases the resumption of the current proceeding against all four firms.

In the event that the SEC restarts the administrative proceedings, depending upon the final outcome, listed companies in the United States with major PRC operations may find it difficult or impossible to retain auditors in respect of their operations in the PRC, which could result in financial statements being determined to not be in compliance with the requirements of the Securities Exchange Act of 1934, as amended, or the Exchange Act, including possible delisting. Moreover, any negative news about any such future proceedings against these audit firms may cause investor uncertainty regarding China-based, United States-listed companies and the market price of our ADSs may be adversely affected.

If our independent registered public accounting firm were denied, even temporarily, the ability to practice before the SEC and we were unable to timely find another registered public accounting firm to audit and issue an opinion on our financial statements, our financial statements could be determined not to be in compliance with the requirements of the Exchange Act. Such a determination could ultimately lead to the delisting of our ordinary shares from the NYSE Global Market or deregistration from the SEC, or both, which would substantially reduce or effectively terminate the trading of our ADSs in the United States.

The audit report included in this annual report is prepared by an auditor who is not inspected by the Public Company Accounting Oversight Board and, as such, you are deprived of the benefits of such inspection.

Our independent registered public accounting firm that issues the audit reports included in this annual report, as an auditor of companies that are traded publicly in the United States and a firm registered with the PCAOB, is required by the laws of the United States to undergo regular inspections by the PCAOB to assess its compliance with the laws of the United States and professional standards. Because our auditors are located in the People’s Republic of China, a jurisdiction where the PCAOB is currently unable to conduct inspections without the approval of the Chinese authorities, our auditors are not currently inspected by the PCAOB.

Inspections of other firms that the PCAOB has conducted outside of China have identified deficiencies in those firms’ audit procedures and quality control procedures, which may be addressed as part of the inspection process to improve future audit quality. This lack of PCAOB inspections in China prevents the PCAOB from regularly evaluating our auditor’s audits and its quality control procedures. As a result, investors may be deprived of the benefits of PCAOB inspections.

The inability of the PCAOB to conduct inspections of auditors in China makes it more difficult to evaluate the effectiveness of our auditor’s audit procedures or quality control procedures as compared to auditors outside of China that are subject to PCAOB inspections. Investors may lose confidence in our reported financial information and procedures and the quality of our financial statements.

Restrictions on currency exchange under Chinese laws may limit our ability to convert cash derived from our operating activities into foreign currencies and may materially and adversely affect the value of your investment.

Substantially all of our revenues and operating expenses are denominated in Renminbi. Under the relevant foreign exchange restrictions in China, conversion of the Renminbi is permitted, without the need for SAFE approval, for “current account” transactions, which includes dividends, trade, and service-related foreign exchange transactions. Conversion of the Renminbi for “capital account” transactions, which includes foreign direct investment and loans, is still subject to significant limitations and requires approvals from and registration with SAFE and other Chinese regulatory authorities. We cannot assure you that SAFE or other Chinese governmental authorities will not further limit, or eliminate, our ability to purchase foreign currencies in the future. Any existing and future restrictions on currency exchange in China may limit our ability to convert cash derived from our operating activities into foreign currencies to fund expenditures denominated in foreign currencies. If the foreign exchange restrictions in China prevent us from obtaining U.S. dollars or other foreign currencies as required, we may not be able to pay dividends in U.S. dollars or other foreign currencies to our shareholders, including holders of our ADSs. Furthermore, foreign exchange control in respect of the capital account transactions could affect our Chinese subsidiaries’ ability to obtain foreign exchange or conversion into RMB through debt or equity financing, including by means of loans or capital contributions from us.

We face risks related to health epidemics and other outbreaks.

Our business could be adversely affected by the effects of swine flu, avian flu, Severe Acute Respiratory Syndrome, or SARS or other epidemics or outbreaks. China reported a number of cases of SARS in April 2004. In 2006, 2007 and 2008, there were reports of occurrences of avian flu in various parts of China, including a few confirmed human cases and deaths. In April 2009, an outbreak of swine flu occurred in Mexico and the United States and human cases of swine flu were discovered in China and Hong Kong. In April 2013, there were reports of occurrences of avian flu in various parts of China, including a number of confirmed human cases and deaths. Any prolonged occurrence or recurrence of swine flu, avian flu, SARS, Ebola or other adverse public health developments in China or any of the major markets in which we do business may have a material adverse effect on our business and operations. These could include our ability to deliver our products within or outside of China, as well as temporary closure of our manufacturing facilities, or our customers’ facilities, leading to delayed or cancelled orders. Any severe travel or shipment restrictions and closures would severely disrupt our operations and adversely affect our business and results of operations.

Risks Related to Our ADSs

The trading prices of our ADSs have been and may continue to be volatile, which could result in substantial losses to investors.

The closing trading prices of our ADSs ranged from $21.86$12.40 to $54.83$26.95 in 2014,2016, and may remain volatile in the future and could fluctuate widely due to factors beyond our control. This may happen because of broad market and industry factors, like the performance and fluctuation of the market prices of other companies with business operations located mainly in China that have listed their securities in the United States. A number of China-based companies, including many solar energy companies, have listed their securities on U.S. stock exchanges. The securities of some of these companies have experienced significant volatility, including price declines in connection with their initial public offerings. The trading performances of these Chinese companies’ securities after their offerings may affect the attitudes of investors toward Chinese companies listed in the United States in general and consequently may impact the trading performance of our ADSs, regardless of our actual operating performance.

In addition to market and industry factors, the price and trading volume for our ADSs may be volatile for factors specific to our own operations, including the following:

Any of these factors may result in large and sudden changes in the volume and price at which our ADSs will trade. We cannot assure you that these factors will not occur in the future.

The sale or availability for sale of substantial amounts of our ADSs could adversely affect their market price.

Sales of substantial amounts of our ADSs in the public market or the perception that these sales could occur, could adversely affect the market price of our ADSs and could materially impair our ability to raise capital through equity offerings in the future. Our ADSs are freely tradable without restriction or further registration under the U.S. Securities Act of 1933, as amended, or the Securities Act, subject to the restrictions in Rule 144 and Rule 701 under the Securities Act. In addition, market sales of securities held by our significant shareholders or any other shareholder or the availability of these securities for future sale may adversely affect the market price of our ADSs.

Our ThirdFourth Amended and Restated Memorandum and Articles of Association contain anti-takeover provisions that could have a material adverse effect on the rights of holders of our ordinary shares and ADSs.

Our ThirdFourth Amended and Restated Memorandum and Articles of Association contain provisions to limit the ability of others to acquire control of our company or cause us to engage in change-of-control transactions. These provisions could have the effect of depriving our shareholders of an opportunity to sell their shares at a premium over prevailing market prices by discouraging third parties from seeking to obtain control of our company in a tender offer or similar transaction.

You may face difficulties in protecting your interests, and your ability to protect your rights through U.S. courts may be limited, because we are incorporated under Cayman Islands law.

We are an exempted company incorporated under the laws of the Cayman Islands. Our corporate affairs are governed by our memorandum and articles of association, as amended from time to time, the Companies Law of the Cayman Islands, as amended from time to time, and the common law of the Cayman Islands. The rights of shareholders to take actions against the directors, actions by minority shareholders and the fiduciary responsibilities of our directors to us under Cayman Islands law are to a large extent governed by the common law of the Cayman Islands. The common law of the Cayman Islands is derived in part from comparatively limited judicial precedent in the Cayman Islands as well as from the common law of England, the decisions of whose courts are of persuasive authority, but are not binding, on a court in the Cayman Islands. The rights of our shareholders and the fiduciary responsibilities of our directors under Cayman Islands law are not as clearly established as they would be under statutes or judicial precedent in some jurisdictions in the United States. In particular, the Cayman Islands has a less developed body of securities laws than the United States. Some U.S. states, such as Delaware, have more fully developed and judicially interpreted bodies of corporate law than the Cayman Islands. In addition, Cayman Islands companies may not have standing to initiate a shareholder derivative action in a federal court of the United States.

The Cayman Islands courts are also unlikely:

There is no statutory recognition in the Cayman Islands of judgments obtained in the United States, although the courts of the Cayman Islands will in certain circumstances recognize and enforce a non-penal judgment of a foreign court of competent jurisdiction without retrial on the merits.

As a result of all of the above, public shareholders may have more difficulty in protecting their interests in the face of actions taken by management, members of the board of directors or controlling shareholders than they would as public shareholders of a company incorporated in the United States.

Certain judgments obtained against us by our shareholders may not be enforceable.

We are a Cayman Islands company and all of our assets are located outside of the United States. Substantially all of our current operations are conducted in the China. In addition, a majority of our current directors and officers are nationals and residents of countries other than the United States. Substantially all of the assets of these persons are located outside the United States. As a result, it may be difficult or impossible for you to bring an action against us or against these individuals in the United States in the event that you believe that your rights have been infringed under the United States federal securities laws or otherwise. Even if you are successful in bringing an action of this kind, the laws of the Cayman Islands and of China may render you unable to enforce a judgment against our assets or the assets of our directors and officers.

The voting rights of holders of ADSs are limited by the terms of the deposit agreement, and you may not be able to exercise your right to vote your ordinary shares.

As a holder of our ADSs, you will only be able to exercise the voting rights with respect to the underlying ordinary shares in accordance with the provisions of the deposit agreement. Under the deposit agreement, you must vote by giving voting instructions to the depositary. Upon receipt of your voting instructions, the depositary will vote the underlying ordinary shares in accordance with these instructions. You will not be able to directly exercise your right to vote with respect to the underlying shares unless you withdraw the shares. Under our ThirdFourth Amended and Restated Memorandum and Articles of Association, the minimum notice period required for convening a general meeting is seven days. When a general meeting is convened, you may not receive sufficient advance notice to withdraw the shares underlying your ADSs to allow you to vote with respect to any specific matter. If we ask for your instructions, the depositary will notify you of the upcoming vote and will arrange to deliver our voting materials to you. We cannot assure you that you will receive the voting materials in time to ensure that you can instruct the depositary to vote your shares. In addition, the depositary and its agents are not responsible for failing to carry out voting instructions or for their manner of carrying out your voting instructions. This means that you may not be able to exercise your right to vote and you may have no legal remedy if the shares underlying your ADSs are not voted as you requested.

The depositary for our ADSs will give us a discretionary proxy to vote our ordinary shares underlying your ADSs if you do not vote at shareholders’ meetings, except in limited circumstances, which could adversely affect your interests.

Under the deposit agreement for the ADSs, if you do not vote, the depositary will give us a discretionary proxy to vote our ordinary shares underlying your ADSs at shareholders’ meetings unless:

The effect of this discretionary proxy is that if you do not vote at shareholders’ meetings, you cannot prevent our ordinary shares underlying your ADSs from being voted, except under the circumstances described above. This may make it more difficult for shareholders to influence the management of our company. Holders of our ordinary shares are not subject to this discretionary proxy.

You may not receive dividends or other distributions on our ordinary shares and you may not receive any value for them, if it is illegal or impractical to make them available to you.

The depositary of our ADSs has agreed to pay to you the cash dividends or other distributions it or the custodian receives on ordinary shares underlying our ADSs, after deducting its fees and expenses. You will receive these distributions in proportion to the number of ordinary shares your ADSs represent. However, the depositary is not responsible if it decides that it is unlawful or impractical to make a distribution available to any holders of ADSs. For example, it would be unlawful to make a distribution to a holder of ADSs if it consists of securities that require registration under the Securities Act but that are not properly registered or distributed under an applicable exemption from registration. The depositary may also determine that it is not feasible to distribute certain property through the mail. Additionally, the value of certain distributions may be less than the cost of mailing them. In these cases, the depositary may determine not to distribute such property. We have no obligation to register under U.S. securities laws any ADSs, ordinary shares, rights or other securities received through such distributions. We also have no obligation to take any other action to permit the distribution of ADSs, ordinary shares, rights or anything else to holders of ADSs. This means that you may not receive distributions we make on our ordinary shares or any value for them if it is illegal or impractical for us to make them available to you. These restrictions may cause a material decline in the value of our ADSs.

You may not be able to participate in rights offerings and may experience dilution of your holdings.

We may, from time to time, distribute rights to our shareholders, including rights to acquire securities. Under the deposit agreement, the depositary will not distribute rights to holders of ADSs unless the distribution and sale of rights and the securities to which these rights relate are either exempt from registration under the Securities Act with respect to all holders of ADSs, or are registered under the provisions of the Securities Act. The depositary may, but is not required to, attempt to sell these undistributed rights to third parties, and may allow the rights to lapse. We may be unable to establish an exemption from registration under the Securities Act, and we are under no obligation to file a registration statement with respect to these rights or underlying securities or to endeavor to have a registration statement declared effective. Accordingly, holders of ADSs may be unable to participate in our rights offerings and may experience dilution of their holdings as a result.

You may be subject to limitations on transfer of your ADSs.

Your ADSs are transferable on the books of the depositary. However, the depositary may close its books at any time or from time to time when it deems expedient in connection with the performance of its duties. The depositary may close its books from time to time for a number of reasons, including in connection with corporate events such as a rights offering, during which time the depositary needs to maintain an exact number of ADS holders on its books for a specified period. The depositary may also close its books in emergencies, and on weekends and public holidays. The depositary may refuse to deliver, transfer or register transfers of our ADSs generally when our share register or the books of the depositary are closed, or at any time if we or the depositary thinks it is advisable to do so because of any requirement of law or of any government or governmental body, or under any provision of the deposit agreement, or for any other reason.

We may be classified as a passive foreign investment company, or PFIC, for U.S. federal income tax purposes, which could subject U.S. investors in our ADSs or ordinary shares to adverse tax consequences.

A non-United States corporation, such as our company, will be classified as a PFIC, for United States federal income tax purposes, for any taxable year if either (i) 75% or more of its gross income consists of certain types of “passive” income or (ii) 50% or more of the value of its assets (determined on the basis of a quarterly average) produce or are held for the production of passive income. Based on our current income and assets, we do not expect to be classified asbelieve that we were a PFIC for the current taxable year ended December 31, 2016 and do not anticipate becoming a PFIC in future taxable years, although there can be no assurance in this regard. Although we do not currently expect that our assets or activities will change in a manner that would cause us to become a PFIC for our current taxable year or the foreseeable future, there can be no assurance our business plans will not change in a manner that will affect our PFIC status. Because there are uncertainties in the application of the relevant rules and PFIC status is a fact-intensive determination made on an annual basis, no assurance can be given that we are not or will not become classified as a PFIC.

If we were to be classified as a PFIC in any taxable year, a U.S. Holder (as defined in “Item 10. Additional Information — E. Taxation — United States Federal Income Tax Considerations”) may incur significantly increased United States federal income tax on gain recognized on the sale or other disposition of the ADSs or ordinary shares and on the receipt of distributions on the ADSs or ordinary shares to the extent such gain or distribution is treated as an “excess distribution” under the United States federal income tax rules. Further, if we are classified as a PFIC for any year during which a U.S. Holder holds our ADSs or ordinary shares, we generally will continue to be treated as a PFIC for all succeeding years during which such U.S. Holder holds our ADSs or ordinary shares. See “Item 10. Additional Information — E. Taxation — United States Federal Income Tax Considerations—Considerations — Passive Foreign Investment Company Rules.Considerations” and “ —  Passive Foreign Investment Company Rules” for more information.”

We are a “foreign private issuer”, and have disclosure obligations that are different from those of U.S. domestic reporting companies; as a result, you should not expect to receive the same information about us at the same time when a U.S. domestic reporting company provides the information required to be disclosed.

We are a foreign private issuer and, as a result, we are not subject to the same requirements that are imposed upon U.S. domestic issuers by the SEC. Under the Exchange Act, we will be subject to reporting obligations that, to some extent, are more lenient and less frequent than those of U.S. domestic reporting companies. For example, we are not required to issue quarterly reports or proxy statements. We have 120 days to file our annual report with the SEC for the fiscal years ending on or after December 31, 2011. We are not required to disclose detailed individual executive compensation information that is required to be disclosed by U.S. domestic issuers. Further, our directors and executive officers are not required to report equity holdings under Section 16 of the Securities Act and are not subject to the insider short-swing profit disclosure and recovery regime. As a foreign private issuer, we are also exempt from the requirements of Regulation FD (Fair Disclosure) which, generally, are meant to ensure that select groups of investors are not privy to specific information about an issuer before other investors. We are, however, still subject to the anti-fraud and anti-manipulation rules of the SEC, such as Rule 10b-5 under the Exchange Act. Since many of the disclosure obligations imposed on us as a foreign private issuer are different than those imposed on U.S. domestic reporting companies, our shareholders should not expect to receive the same information about us and at the same time as the information received from, or provided by, U.S. domestic reporting companies.

If securities or industry analysts do not actively follow our business, or if they publish unfavorable research about our business, our ADS price and trading volume could decline.

The trading market for our ADS depends in part on the research and reports that securities or industry analysts publish about us or our business. If one or more of the analysts who covers us downgrades our ADSs or publishes unfavorable research about our business, our ADS price would likely decline. If one or more of these analysts ceases coverage of our company or fails to publish reports on us regularly, demand for our ADSs could decrease, which could cause our ADS price and trading volume to decline.

ITEM 4. INFORMATION ON THE COMPANY

A. History and Development of the Company

Our company was incorporated in Cayman Islands as Mega Stand International Limited in November 2007. We changed our corporate name to Daqo New Energy Corp. in August 2009.

We are a company limited by shares domiciled in the Cayman Islands. The corporate affairs of Daqo New Energy Corp. are governed by our ThirdFourth Amended and Restated Memorandum and Articles of Association, the Companies Law (2013(2016 Revision) of the Cayman Islands and the common law of the Cayman Islands.

In 2008, we established Chongqing Daqo as our wholly owned operating subsidiary in China. Through Chongqing Daqo, we focus primarily on the manufacture and sale of polysilicon and have expanded into wafer manufacturing. In addition to Chongqing Daqo, we established Nanjing Daqo New Energy Co., Ltd., or Nanjing Daqo, in 2007 in China, through which we conducted our module manufacturing business. In 2009, we established our wholly owned subsidiary Daqo Solar Energy North America, or Daqo North America, in California to promote our products in North America. In 2011, we established a wholly owned subsidiary, Daqo New Energy Holdings (Canada) Ltd., or Daqo Canada, to expand our operations in Canada. In 2011, to expand our polysilicon manufacturing capacity, we established another wholly owned subsidiary, Xinjiang Daqo, in China.

Daqo Group established Daqo New Material in 2006 in Chongqing, China. Although all of Daqo Group’s equity interest holders also beneficially own shares of Daqo Cayman, Daqo Group does not have any shareholding in our company. As of the date of this annual report, holders of equity interests in Daqo Group in aggregate beneficially own 58.5%47.8% of the outstanding ordinary shares of our company. Subsequent to the establishment of Chongqing Daqo, in July 2008, Chongqing Daqo entered into a lease agreement with Daqo New Material to rent all of Daqo New Material’s land, production infrastructure, machinery, equipment, facilities, factories, buildings and other assets for polysilicon production. This lease was terminated on December 30, 2013. Under Financial Accounting Standards Board Accounting Standards Codification 810-10-15, “Variable Interest Entities,” we were deemed to be Daqo New Material’s primary beneficiary and Daqo New Material had been consolidated from July 1, 2008 to December 30, 2013.

We commenced commercial production at the Phase 1 polysilicon facilities in July 2008. Production at the Phase 1 polysilicon facilities used equipment and property of both us and Daqo New Material.

Even though we do not directly or indirectly hold any equity interests in Daqo New Material, under U.S. GAAP, Daqo New Material has been deemed to be our predecessor business from November 16, 2006 through June 30, 2008.

Under a non-competition agreement with us, Daqo Group has agreed not to engage in the business of manufacturing, marketing or distributing polysilicon or any other solar power products anywhere in the world or compete in any manner with our businesses without our consent for an indefinite term. Such related party transactions are subject to our audit committee’s review and approval. Under the non-competition agreement, we, through Daqo Cayman and Chongqing Daqo, are entitled to seek temporary restraining orders, injunctions or other equitable relief, in addition to monetary remedies specified in the agreement, if Daqo Group breaches its non-competition obligations. With the approval of our audit committee, we gave our consent to Daqo Group to enter the photovoltaic cell manufacturing business in China. Daqo Group incorporated the wholly owned subsidiary, Zhenjiang Daqo Solar Co., Ltd., or Zhenjiang Daqo, which started commercial production of photovoltaic cells in 2011.

On October 7, 2010, we listed our ADSs, each representing five ordinary shares of Daqo New Energy Corp., on the New York Stock Exchange, or the NYSE, under the symbol “DQ” in connection with an initial public offering. We issued a total of 9,200,000 ADSs at $9.50 per ADS in connection with our initial public offering.

In February 2011, we incorporated a wholly owned subsidiary, Xinjiang Daqo, in Shihezi Economic Development Area in Xinjiang Autonomous Region, China, to build our Phase 2a2A polysilicon production facilities. We finished construction of our Phase 2a2A polysilicon facilities in September 2012 and have engaged in commercial production at these facilities since the first quarter of 2013.

In April 2011, we incorporated a wholly owned subsidiary, Daqo Canada, to expand our operations in North America. Through Daqo Canada, we set up a joint venture with JNE Solar Inc., a party unrelated to us prior to this transaction, in Hamilton, Ontario. This joint venture was terminated in April 2012. We liquidated Daqo Canada in October 2013.

In September 2012, to focus on our core businesses of polysilicon and wafer production, we sold our 100% equity interest in our module business to Daqo Group for a consideration of $9.9 million. On December 21, 2012, we effected a change of the ADS to ordinary share ratio from one ADS representing five ordinary shares to one ADS representing 25 ordinary shares. The ratio change had the same effect as a 1-for-5 reverse ADS split.

In September 2012, we halted polysilicon production in order to begin maintenance and technology improvement projects at the Phase 1 polysilicon facilities with the primary objective of lowering the cost to produce polysilicon at these facilities. In conjunction with the production stoppage, a supplementary lease agreement with Daqo New Material was reached which reduced lease payments beginning in 2013 to approximately $0.

In the first quarter of 2013, we terminated Daqo North America, which was originally designed to promote our module products in North America. In the second quarter of 2013, we incurred fixed asset impairment charges related to the Phase 1 polysilicon facilities to reflect the market challenges that had an adverse effect on the profit-generating ability of the assets.

As of March 2013, we successfully reached our initial targets for both capacity and cost structure for our Xinjiang polysilicon facilities. As part of our efforts toward further improvement, we successfully completed a project to identify and reduce restrictions on our production throughput, or a “debottlenecking” project, prior to the end of 2013.

In November 2013, our board of directors approved our plan to further expand our capacity in Xinjiang from 6,150 MT to 12,150 MT, or the Phase 2b2B expansion, in order to take advantage of the enormous competitive advantage in electricity price in Xinjiang compared to that of Chongqing. We are also in the process of upgrading our off-gas treatment process from traditional Hydrogenation technology to Hydrochlorination technology.

Since we will not continue the technology improvement project in our Phase 1 facilities and we plan to relocate the idle machinery and equipment from Phase 1 facilities in Chongqing to Phase 2 facilities in Xinjiang for the expansion project, we (i) ceased production at the Phase 1 polysilicon facilities in 2013 and 2014, (ii) started the relocation of certain machinery and equipment from the Phase 1 polysilicon facilities to Xinjiang and (iii) on December 30, 2013, signed an amendment to the supplementary lease agreement to terminate the lease, which resulted in the de-consolidation of Daqo New Material. To support the wafer manufacturing at Chongqing Daqo, a new lease agreement was entered into with Daqo New Material to lease a small portion of its facilities, including, but not limited to, the dining hall, part of the office buildings and portions of the employee dormitory, on January 1, 2014.

Following the completion of our Phase 2a2A and our capacity enhancement project for Phase 2a,2A, we fully ramped up our nameplate polysilicon production capacity to 6,150 MT per annum in the first quarter of 2014.

InWe fully ramped up the full production capacity of our Phase 2B project to 12,150 MT per annum at the end of the third quarter of 2014, the manufacturing process in2015, which reduced our Xinjiang facilities was further optimized,average production cost (including depreciation) and production efficiency was improved. As a result, our production volume exceeded the nameplate capacity by 9%, without adding any additional equipment. We produced 1,748 MTcash cost (excluding depreciation) to $9.74/kg and 1,791 MT of polysilicon$7.69/kg in the third and fourth quarter of 2014,2015, respectively.

In July 2015, our board of directors approved our Phase 3A expansion project. We completed the construction and installation of Phase 3A at the end of 2016 and commenced initial production in the first quarter of 2017. As of the date of this annual report, we are on track with our schedule of the construction and installation work related to the Phase 2b project at our Xinjiang polysilicon facilities. We expect to fully ramp up our nameplate polysiliconhave achieved full production capacity to 12,150of 18,000 MT per annum by the end of the second quarter of 2015, which will reduce our production cost (including depreciation) and cash cost (excluding depreciation) of polysilicon production to $12.0/kg and $8.7/kg, respectively.annum.

We are in the process of relocating certain machinery and equipment from our facilities in Chongqing to our Xinjiang facilities, which has reduced the capital expenditure requirements for our Phase 2b project. However,2B and 3A projects. In addition, we have decided to utilizeutilized approximately 40%81% of our current machinery and equipment previously planned to be used for our Phase 2b project, as measured by its book value as of December 31, 2014, as certain2016, and have determined that the remaining machinery and equipment can be more efficiently and cost-effectively used in our future expansions. As a result, we plan to acquire additional new machinery and equipment for our Phase 2b project. Our estimate of the total investment amount for our Phase 2b andpotential future expansions, has not changed, and subsequently, the total cash requirement for Phase 2b is now expected to be approximately $151.9 million.

We are also considering further capacity expansion at our Xinjiang facilities in the medium term, the Phase 3 project. Subject to market and industry conditions, we expect our Phase 3 project, which may be conducted in two stages, to expand total polysilicon production capacity to 25,000 MT by early 2017. The remaining Chongqing machinery and equipment that we do not utilize in our Phase 2b project will be used in the Phase 3 project, which will reduce our capital expenditure requirements.requirements in future expansions.

In November 2013, we achieved great progress in our wafer business by increasing our annual capacity from 36 million pieces to 72 million pieces. Since 2014, we have been running our wafer business in full capacity and improved the quality and efficiency for our wafer products. In May 2014, we established in-house slurry recovery system, which helps us to lower the wafer production cost. In November 2015, we launched a wafer technology enhancement project at our Chongqing wafer facilities, which is expected to reduce our wafer manufacturing cost and increase our wafer capacity with a limited capital expenditure requirement. We upgraded our ingot furnaces from Generation 5 to Generation 6 directional solidification casting furnaces and increased our ingot output from approximately 500 kilograms per batch to approximately 800 kilograms per batch. We also increased our wafering capacity by improving efficiency of the existing wafering system and acquiring certain used wafering tools from the secondary market. By the end of the second quarter of 2016, we successfully completed this project and increased our annual wafer capacity from the 87 million pieces to approximately 100 million pieces.

In August 2015, our board of directors and the audit committee approved the restructuring plan of Xinjiang Daqo in order for it to meet certain PRC legal requirement for listing on the National Equities Exchange and Quotations, or the New Third Board, an emerging over-the-counter securities market in China. Pursuant to the restructuring plan, Xinjiang Daqo Investment subscribed for newly issued equity interest of Xinjiang Daqo representing 1% of the total outstanding equity of Xinjiang Daqo, which restructuring was completed in December 2015. We are holding 99% of the outstanding equity interest of Xinjiang Daqo. In April 2016, Xinjiang Daqo has received approval to list its shares on the New Third Board. In June 2016, Xinjiang Daqo was listed on the New Third Board.

In December 2016, we adopted a dual Chinese name “大全新能源公司” at our annual general meeting, so that the name of our company is “Daqo New Energy Corp.大全新能源公司”.

Our principal executive offices are located at 666 Longdu Avenue, Wanzhou, Chongqing 404000, People’s Republic of China, and our telephone number at that location is +86-23-6486-6666. Our registered office in the Cayman Islands is located at the offices of International Corporation Services Ltd., P.O. Box 472, 2nd Floor Harbor Place, Grand Cayman KY1-1106, Cayman Islands. Our agent for service of process in the United States is Law Debenture Corporate Services Inc., located at 400 Madison Avenue, 4th Floor, New York, NY 10017.

B. Business Overview

Photovoltaics is one of the proven and most rapidly growing renewable energy sources in the world. Energy from the sun is converted into electricity primarily through the photovoltaic effect and, to a lesser extent, through concentrated solar thermal technologies.

We are a leading high-purity polysilicon manufacturer based in China. We utilize the chemical vapor deposition process, or the “modified Siemens process,” to produce polysilicon, and have fully implemented the closed loop system to produce high-quality polysilicon cost-effectively. We manufacture and sell high-qualityhigh-purity polysilicon to photovoltaic product manufacturers, who further process our polysilicon into ingots, wafers, cells and modules for solar power solutions. Currently, our annual capacity for polysilicon is 6,15018,000 MT in Xinjiang. We plan to further increase the capacity to 12,150 MT by the end of the second quarter of 2015. We are also in the process of upgradinghave successfully upgraded our off-gas treatment process from traditional Hydrogenation technology to Hydrochlorination technology. We improve our production efficiency and increase our output through technological improvements, adoption of process innovation and refinement as well as equipment enhancement. Actual production volume may exceed the production capacity due to operational improvements we may implement at our facilities in response to market conditions.

We have expanded to the downstream photovoltaic manufacturing businesses to establish facilities for wafer manufacturing. Our currentAs of the end of 2016, our wafer manufacturing annual capacity is 72approximately 100 million pieces. We have started to reportreported wafer shipments in units of “million pieces” instead of “MW” since the first quarter of 2013. Improvements in wafer technology can cause watts per piece to increase, resulting in larger MW shipments without increases in the amount of wafer produced, and consequently we believe that the newly adopted unit more accurately presents our operating performance. Most of our wafer product is high efficiency wafer which represents approximately 4.3 watts per piece. The following diagram illustrates the value chain for the manufacture of crystalline-silicon based photovoltaic products:

Our operations are located in Chongqing and Xinjiang, which are in southwestern and northwestern China, respectively. The cost of doing business in western China is generally lower than the coastal areas of China. Specifically, in Xinjiang where our polysilicon facilities are located, the electricity rate is much lower than the coastal areas. Because of our strategic locations, we experience advantages in electricity and raw material costs over our competitors that are based in developed countries or in the coastal areas of China.

We impose rigorous quality control standards at various stages of our manufacturing process. We systematically test raw materials from our suppliers and test our inputs at each stage of our manufacturing process to ensure that they meet all technical specifications. With our strict quality control measures in our manufacturing and facility construction processes, we are able to produce high-quality polysilicon consistently at our facilities. In 2014,2016, approximately 100%96.0% of our polysilicon met the solar grade I standard, , the highest specification of the solar grade quality standard, and approximately 86.6%12.2% of our polysilicon met the electronic grade quality standard in China.

We have achieved substantial growth since we commenced commercial production of polysiliconChina, which standard was updated in July 2008. Our revenue and gross margin continued to improve in 2014 due to a recovery in the global market and our continuous cost reduction efforts. We produced 3,349 MT⁽¹⁾, 4,805 MT and 6,560 MT of polysilicon and sold 3,262 MT⁽²⁾⁽³⁾, 4,283 MT⁽³⁾ and 5,972 MT⁽³⁾ in 2012, 2013 and 2014, respectively. We generated revenues from continuing operations of $86.9 million, $109.0 million and $182.6 million in 2012, 2013 and 2014, respectively. We incurred net losses attributable to Daqo New Energy Corp. shareholders of $111.9 million and $70.9 million in 2012 and 2013 respectively. We achieved net income attributable to Daqo New Energy Corp. shareholders of $16.7 million in 2014.

2016. We currently sell polysilicon to China-based photovoltaic product manufacturers. The majority of our sales are made under framework contracts, with the prices to be determined at the time when specific sales orders are made. As of December 31, 2014,2016, our major photovoltaic product customers included operating entities of JiangsuJinko Solar, Meike Silicon Energy, JinkoSolar, JAKonca Solar, Shanghai Alex NewJinneng Clean Energy and LDKJA Solar.

We commenced commercial production of wafers using our own polysilicon in July 2011. In November 2013,2015, we launched a wafer technology enhancement project at our Chongqing wafer facilities, which is expected to reduce our wafer manufacturing cost and increase our wafer capacity with a limited capital expenditure requirement.

We upgraded our ingot furnaces from Generation 5 to Generation 6 directional solidification casting furnaces and increased our ingot output from approximately 500 kilograms per batch to approximately 800 kilograms per batch. We also increased our wafering capacity by improving efficiency of the existing wafering system and acquiring certain used wafering tools from the secondary market. By the end of the second quarter of 2016, we successfully completed this project and increased our annual wafer production capacity from the 87 million pieces to 72approximately 100 million pieces. In addition to our wafer sales, since the second quarter of 2012, we started to provide multi-crystalline ingot and block manufacturing outsourcing services to our customers.

In May 2010, we commenced commercial production of modules. We sold all of our module facilities in September 2012 to focus on our core businesses of polysilicon and wafer production. The operation of our downstream photovoltaic product manufacturing business involves risks and uncertainties, such as higher cost, lack of experience, financing, construction and operational uncertainties, potential competition and regulatory risks. See “Item 3. Key Information — D. Risk Factors — Risks Related to Our Business” for details.

Manufacturing Process

Polysilicon

Modified Siemens Process

Three main technologies are used in polysilicon production: the Siemens process, the fluidized bed reactor process and the newly developed upgraded metallurgical grade silicon process. The Siemens process is an existing and well proven process technology predominantly used in high purity silicon feedstock production in the solar industry. ThreeThe two other new technologies, the fluidized bed reactor process and the upgrading metallurgical grade silicon process, and the vapor-to-liquid deposition, have the potential for lower cost production but are relatively new and less proven.

We use the modified Siemens process to produce polysilicon. The modified Siemens process includes three distinct steps: (1) TCS production; (2) distillation; and (3) deposition. In addition, we recover and recycle exhaust gas throughout the process in our closed loop manufacturing system. The diagram below describes our current general manufacturing process:

TCS production. The first step of the manufacturing process is to produce TCS from two widely available industrial raw materials: MG-Si and liquid chlorine. We generate TCS in-house through our integrated manufacturing process. TCS production includes two steps: hydrogen chloride synthesis, or HCl synthesis, and TCS synthesis. At the HCl synthesis step, liquid chlorine from a chlorine tank is vaporized to chlorine gas and sent to the HCl synthesis furnace, where it reacts with hydrogen to generate HCl. At the TCS synthesis step that follows, MG-Si powder is then sent to a TCS furnace and reacted with HCl gas. The temperature in the TCS synthesis furnace is maintained at 280–320ºC to facilitate the TCS reaction.

Distillation. Distillation is a method of separating mixtures based on differences in their boiling points. Raw TCS is purified through distillation to produce high purity TCS feedstock. The difference in boiling points of TCS and impurities such as boron, phosphorous, and metal halides allow for purification of TCS. It is critical to remove these impurities in this process to eliminate the possible causes of low performance in solar cells. In the distillation process, all by-product chemicals from vent gases are separated and further purified before being sent back to our production areas.

Deposition. The purified TCS from the distillation process is vaporized, mixed with hydrogen gas, and then fed into the deposition reactor. The mixed gas passes over heated silicon slim rods inside the deposition reactor. In the reactor, multiple pair slim rods are heated up to approximately 1,100°C and high purity silicon is deposited on the rods surface. The constant feeding of TCS and hydrogen gas allows for continuous silicon deposition until 150–200mm in diameter is achieved. At this point the deposition cycle is completed and the ultra pureultra-pure silicon is harvested.

Closed loop manufacturing system

We have implemented the modified Siemens process in a completely closed loop system. The closed loop system is an advanced polysilicon manufacturing process widely used by leading international polysilicon manufacturers. Compared to the open loop system, the closed loop system uses raw materials more efficiently, requires less electricity and produces less pollution. Manufacturing polysilicon generates an exhaust gas primarily consisting of hydrogen, HCl, and chlorosilanes. Using the vent gas recovery system, which combines condensers, distillation towers, adsorption beds and compressors, we are able to separate the exhaust stream from our manufacturing process into individual components that can be reused after further purification. For instance, a by-product of the deposition step is TET, which is a toxic chemical. Through a separate hydrogenationhydrochlorination process, we convert TET to TCS, so that we eliminate the costs related to TET disposal and reduce operational risks of TET treatment. Mixed chlorosilanes are recovered as a liquid stream suitable for separation where we can directly reuse TCS. Anhydrous HCl is recovered with high purity, suitable for use in TCS production. Recovered hydrogen typically contains contaminants of fewer than 10 parts per million and is recycled to the deposition reactors. Recycling significantly reduces costs related to waste disposal and the amount of raw materials we need to purchase for production.

Although the closed loop system has lower manufacturing costs than the open loop system, manufacturing facilities based on the open loop system can be built within a shorter period time with less initial capital investment for equipment. Most of polysilicon manufacturing facilities in China were traditionally built based on the open loop system. However, as the polysilicon market may face downward pricing pressure from time to time, we believe that an increasing number of China-based manufacturers are converting their open loop system to the closed loop system and somemany of them have completed such conversion. The full implementation of the closed loop system by other polysilicon manufacturers has diminished our competitive advantages provided by this system. Nevertheless, in August 2011, Chongqing Daqo entered into a Technology License and Transfer Agreement with GTAT Corporation, a Delaware company, under which GTAT granted us a license to use, in both our Chongqing and Xinjiang facilities, its Hydrochlorination TCS Production Technology and Chlorosilane Recovery/Waste Neutralization Technology,Technology.

We have successfully adopted in our Xinjiang polysilicon manufacturing facilities Hydrochlorination technology, a process which will help expand ourhas seen increasing application in polysilicon manufacturing capacityin recent years. It converts TET (STC) to TCS by reacting with metallurgical grade silicon powder. Using Hydrochlorination technology, chemical reactions take place under much higher pressure and significantly reduceat lower temperatures in comparison to the traditional hydrogenation process. As a result, it consumes less electricity consumption to reduce ourand offers a higher STC/TCS conversion rate. In addition, the Hydrochlorination process also does not require fresh TCS production, costs to reach a more competitive level.which further reduces production costs.

To achieve high efficiency in our manufacturing process, we have also installed a distribution control system and a thermal energy recycling mechanism. The distribution control system enables tight quality control, reduces process related variations, and improves productivity. Our thermal energy recycling system allocates heat generated from our deposition reactors and hydrogenation reactors to many other production areas, such as distillation facilities for TCS purification and our refrigeration station to support a large number of condensers.

Wafer

We conducted our wafer business through tolling arrangements with third party wafer manufacturers in 2009 and 2010. In July 2011, we commenced commercial production of multi-crystalline silicon wafers at our wafer production facilities. In November 2015, we launched a wafer technology enhancement project at our Chongqing wafer facilities, which haveis expected to reduce our wafer manufacturing cost and increase our wafer capacity with a current productionlimited capital expenditure requirement. We upgraded our ingot furnaces from Generation 5 to Generation 6 directional solidification casting furnaces and increased our ingot output from approximately 500 kilograms per batch to approximately 800 kilograms per batch. We also increased our wafering capacity by improving efficiency of 72the existing wafering system and acquiring certain used wafering tools from the secondary market. By the end of the second quarter of 2016, we successfully completed this project and increased our annual wafer capacity from the 87 million pieces to approximately 100 million pieces.

The manufacturing process of wafers typically consists of two major steps: ingot preparation and wafering. Multi-crystalline ingots are prepared by directional solidification in a casting furnace. Silicon ingots will then be shaped to the required sizes and sliced to wafers by wire saws.

Manufacturing Capacity

The following table sets forth our major installed approximate annual production capacity objectives as of the dates indicated and includes the expected date of initial commercial operation and fully ramped-up production of each expansion phase.

Notes:

Our annual polysiliconWe completed the construction and installation of Phase 3A at the end of 2016 and commenced initial production in the first quarter of 2017. By the end of February 2017, we achieved full production capacity reached 6,150of 18,000 MT in 2014. We are in the process of further expanding the capacity of our Xinjiang facilities to 12,150 MT in order to better take advantage of what we believe will be lower production costs in Xinjiang, and optimize utilization of the assets being relocated from the Phase 1 polysilicon facilities. We also plan to upgrade our off-gas treatment process from traditional Hydrogenation technology to Hydrochlorination technology. We expect to fully ramp up capacity in the second quarter of 2015.per annum. Our capacity expansion plan and technology improvement plan are preliminary and subject to risks and uncertainties that may be out of our control. See “Item 3. Key Information — D. Risk Factors — Risks Related to Our Business — Our future success depends substantially on our ability to significantly expand our polysilicon production capacity and output, and to relocate equipment to our Xinjiang facilities, which exposes us to a number of risks and uncertainties” and “Item 3. Key Information — D. Risk Factors — Risks Related to Our Business — If we are unable to manage our expansion effectively, our business and financial results may be adversely affected.”

Materials and Inputs Used in Production

Polysilicon

Raw materials required for our polysilicon manufacturing process primarily include metallurgical grade silicon, which is silicon of 95% to 99% purity, and liquid chlorine, two widely available industrial raw materials used in our in-house production of TCS, electricity and other utilities, and other significant inputs for production, such as argon gas, caustic soda and graphite parts. We produce liquid chlorine in our in-house facilities. This provides us with a reliable supply of liquid chlorine and also helps us to further reduce material costs.

The costs of electricity are significant in the production of polysilicon. The electricity costs in Chongqing are lower than those in coastal areas of China and those in developed countries due to Chongqing’s abundant hydroelectric resources. The costs of electricity in Xinjiang are overapproximately 50% lower than even those in Chongqing due to Xinjiang’s abundant coal resources. We also use other utilities, such as steam, water and natural gas, for our manufacturing process. Steam supply is important to the production of polysilicon. We use both a local supplier and our in-house capabilities to produce steam.

Wafer

Wafer manufacturing uses solar grade polysilicon as the primary raw material and consumables such as crucibles, wires and slurry. We utilize our in-house high quality polysilicon, as well as externally purchased polysilicon for high efficiency wafer production. We have established an in-house slurry recycling system to ensure the quality of re-used slurry and cut slurry cost significantly.

Equipment

The major polysilicon production equipment includes hydroelectrolysis devices, hydrochlorination synthesis furnaces, TCS synthesis furnaces, distillation towers, polysilicon deposition reactors, hydrogenation reactors, exhaust gas recovery units and distribution control systems. The major wafer production equipment includes crystal growing furnaces, crucible coating machines, squarers, wire saws, wet benches and testing tools.

We have close relationships with several of the world’s leading equipment manufacturers and work closely with selected equipment manufacturers to develop and build our production lines. In addition, we developed technical specifications for the design of our power supply systems and reactors and have engaged manufacturers to construct the equipment in accordance with our specifications. Our engineers work closely with our equipment suppliers to design our production facilities. Furthermore, to lower costs, we have purchased and will continue to purchase equipment that can be appropriately designed and manufactured by China-based suppliers. Our technical team is responsible for overseeing the installation of our manufacturing lines to optimize the interaction between the various individual components of the entire production process. They work together with our equipment suppliers’ technical teams on site at the time of installation.

Quality Assurance

We apply our quality control system at each stage of our manufacturing process, from raw materials procurement to production and delivery, in order to ensure a consistent quality of our products. We systematically inspect raw materials from our suppliers, such as MG-Si, liquid chlorine and various consumables for our polysilicon business and polysilicon for our wafer business. We also test our inputs in each stage of our production process to ensure the inputs meet all technical specifications.

We sample each lot of polysilicon harvested from the deposition reactors and keep the samples for product quality tracking purpose. We also set up a product tracking system to trace back all shipped products to the samples we keep and to our database, which contains detailed information of each shipment. We received the ISO 9001:2008 certification for our quality assurance system for both Chongqing and Xinjiang plants, which we believe demonstrates our technological capabilities and inspires customer confidence. In 2009, Chongqing Science and Technology Commission issued a three-year certificate to recognize our polysilicon as a high and new technology product. We have successfully renewed the certificate until November 20152018 and will continue to apply for renewal of the certificate after its expiration in November 2015.expiration. In 2014, Xinjiang Science and Technology Commission issued a three-year certificate to recognize our polysilicon as a high and new technology product. In addition, in 2014, both Chongqing Daqo and Xinjiang Daqo have been recognized for their compliance with the “Photovoltaic Manufacture Industry Standard” issued by the Ministry of Industry and Information Technology of the PRC.

For our wafer production, we inspect all critical incoming materials, such as feedstock silicon, crucible, slurry and wire to ensure they meet our wafer production requirement. Through manufacturing process, technical parameters such as minority lifetime, resistivity, geometry dimension and surface appearance will be checked at various points as part of in-process quality control. As a final product, each wafer is sent to an automatic inspection machine to be inspected against our product technical specifications.

In order to facilitate our production of photovoltaic products and ensure the quality of the finished product, we conduct analysis for raw materials, in-process products and finished products and monitor the environmental impact and safety throughout the production process.

Customers and Sales

We currently sell polysilicon and wafers to China-based photovoltaic product manufacturers. Our major customers include operating entities of JiangsuJinko Solar, Meike Silicon Energy, JinkoKonca Solar, Jinneng Clean Energy and JA Solar, Shanghai Alex New Energy, LDK Solar and other companies.Solar. We sell a substantial portion of our photovoltaic products to a limited number of customers. Our top three customers in aggregate accounted for 40.9%32.1%, 38.5%40.5% and 32.1%37.1% of our total revenues in 2012, 20132014, 2015 and 2014,2016, respectively.

The majority of our polysilicon sales are made under framework contracts. The framework contracts typically provide binding terms for the sales volumes of our polysilicon. The pricing terms are typically agreed upon between us and our customers based on the prevailing market prices when specific sales orders are made. We currently sell all of our wafer products on a spot pricing basis.

We have established nationwide marketing capability through our sales team in China. Each member of our sales team is dedicated to a particular region. Our sales team attends domestic and international industrial conferences and trade fairs and organizes advertising and public relations events. Our sales and marketing team works closely with both our research and development team and our production team to coordinate our ongoing supply and demand planning.

Research and Development

We believe that the continual development of our technology will be vital to maintaining our long-term competitiveness. We have one of the leading research and development teams among polysilicon manufacturers in China. Our research and development team consists of 171388 experienced researchers and engineers. Our senior management team spearheads our research and development efforts and sets strategic directions for the advancement of our products and production processes, focusing on efforts to improve product quality, reduce manufacturing costs and broaden our product markets. In 2014,2016, we completed 2920 research and technology or process improvement projects to enhance our polysilicon and wafer manufacturing processes, and successfully registered 419 patents with the State Intellectual Property Office of the PRC.

Intellectual Property

Our intellectual property is an essential element of our business. We rely on patents, copyrights, trademarks, trade secrets and other intellectual property laws, as well as non-competition and confidentiality agreements with our employees, business partners and others, to protect our intellectual property rights.

As of the date of this annual report, we hold 2554 patents and have 1531 additional pending patent applications covering different aspects of the polysilicon manufacturing process. We also rely heavily on a combination of proprietary process engineering, trade secrets and employee contractual protections to establish and protect our intellectual property, as we believe that many crucial elements of our production processes involve proprietary know-how, technology or data that are not covered by patents or patent applications, including technical processes, equipment designs, algorithms and procedures. We have taken security measures to protect these elements. All of our research and development personnel have entered into confidentiality and proprietary information agreements with us. These agreements address intellectual property protection issues and require our employees to assign to us all of the inventions, designs and technologies that they develop when primarily utilizing our resources or when performing their duties during their employment.

While we continue to develop and pursue patent protection for our own technologies, we expect to continue implementing third party license arrangements on certain key aspects of our operation. For the risks associated with our reliance on certain third-party technologies, see “Item 3. Key Information — D. Risk Factors — Risks Related to Our Business — We rely on third party intellectual property for certain key aspects of our operation,operations, which subjects us to the payment of license fees and potential disruption or delays in the production of our products.” In August 2011, Chongqing Daqo entered into a Technology License and Transfer Agreement with GTAT Corporation, a Delaware company, under which GTAT granted us a license to use its Hydrochlorination TCS Production Technology and Chlorosilane Recovery/Waste Neutralization Technology for our current polysilicon production and future polysilicon production expansions in both our Chongqing and Xinjiang facilities.

Most of our equipment supply contracts with international suppliers include an indemnification provision under which the supplier undertakes to indemnify us against actions, claims, demands, costs, charges, and expenses arising from or incurred by reason of any infringement or alleged infringement of patent, copyright, trade mark or trade name by the use of the equipment provided by the supplier. However, it is unclear whether we will be entitled to such indemnification in the event that we use the equipment supplied by such supplier in conjunction with other equipment not supplied by such supplier. In addition, many of our equipment supply contracts with China-based suppliers do not provide any intellectual property indemnification provisions. See “Item 3. Key Information — D. Risk Factors — Risks Related to Our Business — We may be exposed to infringement or misappropriation claims by third parties, which, if determined adversely to us, could cause us to pay significant damage awards.”

Competition

We face competition in China and in the international markets in which we have sales.

The photovoltaic market is dominated by a few major manufacturers with a large number of small manufacturers competing for the remaining small portion of the market. We face competition mainly from top manufacturers who have succeeded in establishing a strong brand name with solar companies. For our polysilicon and wafer businesses, our major international competitors include Hemlock, Wacker, OCI, REC, SMPMEMC and GreenChinese domestic polysilicon and wafer manufacturers, such as GCL-Poly, Xinte Energy Technology, and our China-based competitors include GCL-Poly, TBEA,Co., Ltd., Asia Silicon Co., Ltd., China Silicon Corporation and LDK Solar, among others.Yongxiang Co., Ltd.There are also likely new entrants into the polysilicon manufacturing market in China, such as Xinjiang East Hope New Energy Ltd. and the joint venture formed by REC and Shanxi Youser. In addition, some solar cell and module manufacturers might have the intention of establishing polysilicon production or affiliate relationships with manufacturers of polysilicon. We compete with these in-house capabilities, which could limit our ability to expand our sales. Furthermore, the demand for our polysilicon may be adversely affected by alternative technologies in cell manufacturing. The vast majority of silicon-based photovoltaic cell manufacturers currently use chunk or granular polysilicon. However, alternative technologies are being developed in cell manufacturing. For example, one such technology, thin-film cell production, uses little to no silicon in the production of solar cells. We believe that the solar cells made using thin-film technologies generally tend to have lower energy conversion efficiency than silicon-based solar cells. In addition, the manufacturing cost of silicon-based cells has been significantly reduced recently, which largely reduces or eliminates the historical cost advantage of thin-film cells. Based on our management’s industry knowledge, we believe silicon-based cells will remain the most widely used solar photovoltaic cells in the near future.

We believe that the key competitive factors in the market for photovoltaic products include:

We believe we differentiate ourselves from our competitors and capture market share in the polysilicon markets through our cost and price competitiveness, product quality, price and cost competitiveness, and manufacturing technologies and efficiency.

Regulation

This section sets forth a summary of the most significant regulations or requirements that affect our business activities in China.

Renewable Energy Law and Other Government Directives

China enacted the Renewable Energy Law in February 2005 and amended the law in December 2009. The amended Renewable Energy Law sets forth the national policy to encourage and support the development and use of solar and other renewable energy and its use for on-grid generation. The law also sets forth the national policy to encourage the installation and use of solar technologies in water-heating systems, heating and cooling systems, power generation systems and other energy utilization systems. In addition, the law provides financial incentives, such as national funding, preferential loans and tax preferences for the development of renewable energy projects.

In January 2006, the National Development and Reform Commission, or the NDRC, issued two implementing rules relating to the Renewable Energy Law that, among other things, provide general policies regarding the pricing of on-grid power generated by solar and other renewable energy.

In May 2006, the Ministry of Finance issued measures providing that the Chinese government shall provide certain government subsidies and financial incentives to support the development of the renewable energy industry, including the solar energy industry.

In August 2006, the Ministry of Housing and Urban-Rural Development (formerly the Ministry of Construction) and the Ministry of Finance also issued guidelines which sought to expand the use of solar energy in residential buildings.

In August 2007, the NDRC promulgated the Medium and Long-Term Development Plan for the Renewable Energy Industry. This plan sets forth national policy to provide financial allowance and preferential tax regulations for the renewable energy industry. A similar demonstration of the PRC government’s commitment to renewable energy was also set forth in the Eleventh Five-Year Plan for Renewable Energy Development, which was promulgated by the NDRC in March 2008. The Outline of the Twelfth Five-Year Plan for National Economic and Social Development of the PRC, which was approved by the National People’s Congress in March 2011, also demonstrates a commitment to promote the development of renewable energy to enhance the competitiveness of the renewable energy industry.

In March 2009, the Ministry of Finance promulgated the Interim Measures for Administration of Government Subsidy Funds for Application of Solar Photovoltaic Technology in Building Construction to support the development of solar photovoltaic technology in China. Local governments are encouraged to issue and implement supporting policies. Also in March 2009, the Ministry of Finance and the Ministry of Housing and Urban-Rural Development jointly promulgated the Implementation Opinion on Acceleration in the Application of Solar Photovoltaic Technology in Building Construction. On March 8, 2011, the Ministry of Finance and Ministry of Housing and Urban-Rural Development jointly promulgated the Notice on Further Application of Renewable Energy in Building Construction, which aims to raise the percentage of renewable energy used in buildings.

In July 2009, the Ministry of Finance, the Ministry of Science and Technology and the National Energy Bureau jointly issued measures that provide for government subsidies to support the photovoltaic industry.

In September 2009, the NDRC and nine other governmental agencies jointly issued measures aimed at curtailing the perceived over-capacity in certain industry sectors, such as steel, concrete, polysilicon and wind power equipment. Pending the promulgation of more specific regulations, the measures require new projects after the date of the new measures in any of the deemed “over-capacity industries” to obtain approval from the NDRC. The measures also provide that the Chinese government shall support polysilicon manufacturers with large manufacturing capacities and advanced technologies. As a result, any entity which plans to establish a polysilicon manufacturing facility or to expand its current manufacturing facility in China after the measures were issued must seek pre-approval from the NDRC.

On January 24, 2011, the NDRC issued detailed regulations for the approval of new polysilicon construction projects.

On July 24, 2011, the NDRC issued the Circular on Improving the On-Grid Price Policy for Photovoltaic Power, which aims to stimulate the photovoltaic power industry by regulating the price of photovoltaic power.

On July 4, 2013, the General Office of the State Council of China issued “Several opinions on promoting healthy development of Solar PV industry” which increased the aggregated target for PV installations as of 2015 from the previously announced 21GW21 GW to 35GW.35 GW.

On September 16, 2013, the Ministry of Industry and Information Technology issued “Regulatory Requirements For the Solar PV Manufacturing Industry” and amended the Regulatory Requirements on March 25, 2015. The amended Regulatory Requirements set forth specific requirements for all sectors through the whole solar PV value chain regarding layout, scale, capacity, quality, efficiency, power consumption, environmental control and certain other elements of PV production, in order to further promote the structualstructural adjustment and the transformation and upgrade of the PV industry, continue to strengthen industry supervision, and enhance the development of the industry.

On In January 2014, the National Energy Administration of China announced the PV installation target for 2014 to be 14GW,14 GW, which includes 8GW8 GW for distributed PV systems and 6GW6 GW for large scale PV power plants.

In March 2015, the National Energy Administration of China announced the PV installation target for 2015 to be 17.8 GW. In December 2015, the NDRC announced that it would cut the solar tariffs in Regions I-III to RMB 0.8/kWh, RMB 0.88/kWh and RMB 0.98/kWh from current RMB 0.9/kWh, RMB 0.95/kWh and RMB 1.0/kWh, respectively, representing reductions of 2% to 11%, effective January 1, 2016. At the same time, China Renewable Energy Fund surcharge fee increased from RMB 15/MWh to RMB 19/MWh.

In December 2016, the NDRC announced the solar power tariff revisions for 2017 as follows. First, in 2017, for solar power plants in resource zones I, II and III, the benchmark feed-in tariffs (FIT) will be lowered from RMB0.80/0.88/0.98/kWh in 2016 to RMB0.65/0.75/0.85/kWh, or by 19%/15%/13%. Second, the subsidy for distributed solar power plants will remain unchanged at RMB0.42/kWh. Third, for solar power projects registered prior to 2017 and eligible for fiscal subsidies, the FIT at the 2016 level will remain applicable if they are connected to the grid and in operation by June 30, 2017. Fourth, future solar power tariffs will be revised annually based on cost changes.

Environmental and Safety Regulations

We use, generate and discharge toxic, volatile or otherwise hazardous chemicals and wastes in our research and development and manufacturing activities. China enacted the Environmental Protection Law effective December 1989. In addition to the Environmental Protection Law, we are subject to a variety of specific laws and regulations in China related to the storage, use and disposal of hazardous materials, including laws and regulations governing water pollution, air pollution, solid waste pollution, noise pollution, hazardous chemicals, pollutant discharge fees and environmental impact appraisals. We are also subject to laws and regulations governing worker safety, work safety permits and occupational disease prevention. Our operation is subject to regulation and periodic monitoring by local environmental protection and work safety authorities.

Foreign Currency Exchange

Under various rules and regulations issued by SAFE and other relevant PRC government authorities, the RMB is convertible for current account items, such as trade related receipts and payments, interest and dividends. Capital account items, such as direct equity investments, loans and repatriation of investment, require the prior approval from SAFE or its local counterpart for conversion of RMB into a foreign currency, such as U.S. dollars, and remittance of the foreign currency outside the PRC.

Payments for transactions that take place within the PRC must be made in RMB. Unless otherwise approved, PRC companies must repatriate foreign currency payments received from abroad. Foreign-invested enterprises may retain foreign exchange in accounts with designated foreign exchange banks subject to a cap set by SAFE or its local counterpart. Unless otherwise approved, domestic enterprises must convert all of their foreign currency receipts into RMB.

Admission of Foreign Investment

The principal regulation governing foreign ownership of solar power businesses in the PRC is the Foreign Investment Industrial Guidance Catalogue. Under the current catalogue, which was amended in 2015 and became effective April 10, 2015, the solar power related business is classified as an “encouraged foreign investment industry.” Companies that operate in encouraged foreign investment industries and satisfy applicable statutory requirements are eligible for preferential treatment, including exemption from customs and input value added taxes, or VAT, and priority consideration in obtaining land use rights.

Foreign Exchange Registration of Offshore Investment by PRC Residents

Pursuant to SAFE Circular 75, issued in October 2005, and a series of implementation rules and guidance, including the circular relating to operating procedures that came into effect in July 2011, PRC residents, including PRC resident natural persons or PRC companies, must register with local branches of SAFE in connection with their direct or indirect offshore investment in an overseas special purpose vehicle, for the purposes of overseas equity financing activities, and to update such registration in the event of any significant changes with respect to that offshore company. SAFE promulgated the Circular on Relevant Issues Concerning Foreign Exchange Control on Domestic Residents’ Offshore Investment and Financing and Roundtrip Investment through Special Purpose Vehicles, or SAFE Circular 37, on July 4, 2014, which replaced the SAFE Circular 75. SAFE Circular 37 requires PRC residents to register with local branches of SAFE in connection with their direct establishment or indirect control of an offshore entity, for the purpose of overseas investment and financing, with such PRC residents’ legally owned assets or equity interests in domestic enterprises or offshore assets or interests, referred to in SAFE No. Circular 37 as a “special purpose vehicle.” The term “control” under SAFE Circular 37 is broadly defined as the operation rights, beneficiary rights or decision-making rights acquired by the PRC residents in the offshore special purpose vehicles or PRC companies by such means as acquisition, trust, proxy, voting rights, repurchase, convertible bonds or other arrangements. SAFE Circular 37 further requires amendment to the registration in the event of any changes with respect to the basic information of the special purpose vehicle, such as changes in a PRC resident individual shareholder, name or operation period; or any significant changes with respect to the special purpose vehicle, such as increase or decrease of capital contributed by PRC individuals, share transfer or exchange, merger, division or other material event. If the shareholders of the offshore holding company who are PRC residents do not complete their registration with the local SAFE branches, the PRC subsidiaries may be prohibited from distributing their profits and proceeds from any reduction in capital, share transfer or liquidation to the offshore company, and the offshore company may be restricted in its ability to contribute additional capital to its PRC subsidiaries. Moreover, failure to comply with SAFE registration and amendment requirements described above could result in liability under PRC law for evasion of applicable foreign exchange restrictions. On February 28, 2015, SAFE promulgated a Notice on Further Simplifying and Improving Foreign Exchange Administration Policy on Direct Investment, or SAFE Notice 13, which will becomebecame effective on June 1, 2015. AfterPursuant to SAFE Notice 13, becomes effective, entities and individuals will beare required to apply for foreign exchange registration of foreign direct investment and overseas direct investment, including those required under the SAFE Circular 37, with qualified banks, instead of SAFE. The qualified banks, under the supervision of SAFE, will directly examine the applications and conduct the registration. The failure or inability of our PRC resident shareholders to comply with the registration procedures may subject the PRC resident shareholders to fines and legal sanctions, restrict our cross-border investment activities, or limit our PRC subsidiaries’ ability to distribute dividends to or obtain foreign exchange-dominated loans from our company. See “Item 3. Key Information — D.

A. Operating Results

Overview

We are a leading high-purity polysilicon manufacturer based in China with an annual production capacity of 6,150 MT as of the date of this annual report.18,000 MT. We believe our production cost for polysilicon is one of the lowest and our product quality is one of the best in China. We have expanded to the downstream photovoltaic manufacturing business to establish facilities for wafer manufacturing. Our currentAs of the end of 2016, our wafer manufacturing annual capacity is 72was approximately 100 million pieces. We had 100MW100 MW module production facilities in Nanjing, all of which we sold to Daqo Group in September 2012.

We strive to improve our polysilicon production efficiency and to increase our output through technological improvements, adoption of process innovation and refinement, as well as equipment enhancement. As a result of these initiatives, we produced 4,524 MT polysilicon in 2011. In 2012, our polysilicon output was 3,349 MT⁽¹⁾, which was less than 2011 due to the suspension of the Phase 1 polysilicon facilities and less than normal output in our Xinjiang facilities during the pilot production period in the fourth quarter of 2012. In 2013, we produced 4,805 MT polysilicon which was all contributed by our Xinjiang facilities. We conducted a “debottlenecking” project for our Xinjiang facilities and successfully completed the project and started pilot production in December 2013. We fully realized capacity of 6,150 MT and lower production costs to the level of $14 per kg in the first quarter of 2014. We are in the process of conductingfully ramped up our Phase 2b2B project to further increase the polysilicon production capacity in our Xinjiang facilities to 12,150 MT which includes relocating machinery and equipment from the Phase 1 polysilicon facilities in Chongqing. We expect to fully ramp up our nameplate production capacity to 12,150 MT per annum byat the end of the secondthird quarter of 2015. We arehave also in the process of upgradingsuccessfully upgraded our off-gas treatment process from traditional Hydrogenation technology to Hydrochlorination technology. In 2015, we produced 9,771 MT polysilicon at an annual average production cost of $11.23/kg (including depreciation). In 2016, we produced 13,068 MT polysilicon at an annually average production cost of $9.38/kg (including depreciation). We are also considering further capacity expansioncompleted the construction and installation of Phase 3A at our Xinjiang facilitiesthe end of 2016 and commenced initial production in the medium term,first quarter of 2017. By the Phase 3 expansion. Subject to market and industry conditions,end of February 2017, we expect our Phase 3 project, which may be conducted in two stages, to expand total polysiliconhave achieved full production capacity to 25,000of 18,000 MT by early 2017.per annum.

We currently sell polysilicon to China-based photovoltaic product manufacturers. The majority of our sales are made under framework contracts, with the prices to be determined at the time when specific sales orders are made. As of December 31, 2014,2016, our major photovoltaic product customers included operating entities of JiangsuJinko Solar, Meike Silicon Energy, JinkoKonca Solar, Jinneng Clean Energy and JA Solar, Shanghai Alex New Energy, LDK Solar and other companies.Solar.

We have expanded to the downstream photovoltaic manufacturing business to establish facilities for wafer manufacturing. Our Phase 1a1A wafer manufacturing facilities in Chongqing commenced commercial production with an annual capacity of 36 million pieces in July 2011. We gradually increased the utilization rate of our wafer facilities in 2013 and successfully expanded the capacity to 72 million pieces in November 2013. Since 2014, we have been running our wafer business in full capacity and improved the quality and efficiency for our wafer products. In May 2014, we established in-house slurry recovery system, which helps us to lower the wafer production cost. In November 2015, we launched a wafer technology enhancement project at our Chongqing wafer facilities, which is expected to reduce our wafer manufacturing cost and increase our wafer capacity with a limited capital expenditure requirement. We upgraded our ingot furnaces from Generation 5 to Generation 6 directional solidification casting furnaces and increased our ingot output from approximately 500 kilograms per batch to approximately 800 kilograms per batch. We also increased our wafering capacity by improving efficiency of the existing wafering system and acquiring certain used wafering tools from the secondary market. By the end of the second quarter of 2016, we successfully completed this project and increased our annual wafer capacity from the 87 million pieces to approximately 100 million pieces.

We have achieved substantial growth since we commenced commercial production of polysilicon in July 2008, though we experienced a significant downturn in terms of revenue and net income in 2012. In 2013, with the recovery of the solar PV market, we achieved an increase of 25.5% in our revenues compared to 2012. Our gross margin also improved from negative 43.1% in 2012 to negative 23.9% in 2013. We produced 3,3496,560 MT,⁽¹⁾, 4,805 9,771 MT and 6,56013,068 MT of polysilicon and sold 3,2625,972 MT^(2)(3)(1), 4,2838,234 MT⁽³⁾⁽¹⁾and 5,97210,883 MT⁽³⁾⁽¹⁾ MT in 2012, 20132014, 2015 and 2014,2016, respectively. We generated revenues from continuing operations of $86.9$182.6 million, $109.0$182.0 million and $182.6$229.1 million in 2012, 20132014, 2015 and 2014, respectively. We incurred net losses attributable to Daqo New Energy Corp. shareholders of $111.9 million and $70.9 million in 2012 and 20132016, respectively. We achieved net income attributable to Daqo New Energy Corp. shareholders of $16.7$16.6 million, $13.0 million and $43.5 million in 2014.2014, 2015 and 2016, respectively

Notes:Note:

Key Factors Affecting Our Results of Operations

The following are key factors that affect our financial condition and results of operations and are important for understanding our business:

Demand for photovoltaic products

Our business and revenue growth are, in part, dependent on the demand for photovoltaic products. The photovoltaic industry remains at a relatively early stage of development and it is uncertain whether solar energy will be widely adopted. Although demand for photovoltaic products has grown significantly over the past decade, the global economic slowdown and turmoil in the global financial markets, especially the European sovereign debt crisis that unfolded in 2010 and the slowdown of the Chinese economy, coupled with rapid declines in petroleum and natural gas prices, have made solar energy less cost competitive and less attractive as an alternative source of energy.

Demand for photovoltaic products is driven, in part, by government incentives that make the economic cost of solar power competitive with the cost of traditional and other forms of energy. We believe that the near-term growth of the market for solar energy applications depends in large part on the availability and size of government subsidies and economic incentives. Petroleum prices started to move downward in the second half of 2014.2014 through the whole year of 2015. If the decrease in petroleum prices continues, government incentives provided to the solar industry in major markets may be reduced. Reduction in or elimination of government subsidies and economic incentives may hinder the growth of this market or result in lower sales prices for solar energy products, which could cause our revenues to decline.

Global solar PV installations in 20142016 totaled around 45.0approximately 73 GW, which representsrepresenting a 23.3%35.1% increase compared to 36.5from 57 GW in 2013. Although2015. China continued to rank the European markets shrank significantly due to subsidy cuts in major markets like Germany, Italy and Spain, the markets in China, Japan and the US took over the leading positions as the three biggest markets forlargest solar PV market globally with total installations of 34.5 GW in 2014. Currently most of2016, with the analyst reports forecast thatUnited States and Japan ranking the second and third largest globally in 2016. In addition, India, the fourth largest solar PV market, is growing rapidly and is expected to install around 10 GW in 2017 and may surpass Japan to become the third largest solar PV market. According to the latest solar PV market report from IHS, we may see a single digit growth in global solar PV installationsmarket in 2015 will be in2017 and 2018, and the range of 52~55 GW, which represents growth of 16%~22%. In March 2015, Chinese National Energy Administration released 2015’s solar PV installation target of 17.8GW, which is 19% higher than the draft target of 15GW, and indicates almost 70% growth from 10.6 GWmarket may grow even faster in 2014. Although some additional polysilicon supply may enter into the market mainly in the second half of 2015, we believe the supply and demand of polysilicon will remain in balance, on the premise that the global markets, including China market, will grow as expected.2019.

Product prices

The sales prices of our photovoltaic products are volatile and cannot always be predicted with certainty. Our sales prices declined from mid-2008 to the middle of 2010 due to industry-wide excess supply but stabilized in the third quarter of 2010 and increased marginally in the fourth quarter of 2010 due to end market demand. In 2011 our sales prices declined rapidly in the fourth quarter primarily due to excess supply in the market. The decline in sales prices continued throughout 2012. Our sales prices started to recover through 2013 due to improved demand and reduced inventory levels. The decline in the market price of polysilicon resulted in an approximately 7% decrease in the average selling price of our polysilicon from 2010 to 2011, a further 59.3% decrease from 2011 to 2012 and a further 23.3% decrease from 2012 to 2013. The market prices for polysilicon and wafer have improved significantly through 2013, albeit not sufficiently to reverse the year-on-year average decrease. In 2014, the average selling prices for polysilicon fluctuated in the range approximately from $20/kg to $22/kg. Our gross margin from continuing operations decreased from positive 37.6% in 2011 to negative 43.1% in 2012 and increased to negative 23.9% in 2013. In 2014, our gross margin from continuing operations improved to 23.7%. In 2015, our quarterly average selling prices for polysilicon decreased by 23.4% from $18.09/kg in the first quarter to $13.86/kg in the fourth quarter of 2015. Our average selling prices for wafers did not change significantly in 2015. In 2015, we achieved gross margin from continuing operations of 20.6% primarily due to significant cost reduction in both of our polysilicon slightly increased to $15.42/kg. In 2016, our gross margin from continuing operations was 35.1% primarily due to significant cost reduction in polysilicon.

Since September 1, 2014, the Chinese government has suspended the review of applications for importing solar grade polysilicon in the processing trade, according to an announcement jointly made by Ministry of Commerce and General Administration of Customs, or GAC, of the PRC in August 2014. All existing agreements approved prior to September 1, 2014 can continue to be performed until the contract terms expire. In addition, certain enterprises in the processing trade business that have been included in the supervisory network of the GAC are allowed to continue to import before the end of 2014. As a result, in the third and fourth quarters of 2014, foreign polysilicon manufacturers increased their supply of polysilicon into China to take advantage of the grace period before the suspension fully kicked in and exerted pressure on the average selling prices of polysilicon. However,In 2015, the volume of imported polysilicon was approximately 117,000 MT, increased from approximately 102,000 MT in 2014. In 2016, the volume of polysilicon imported into China was approximately 140,256 MT. Although we do not expectdid see the increase of supplypolysilicon import volume directly from foreign polysilicon manufacturersthe United States to continuedecline after the contract terms of the existing processing trade agreements expire under the Chinese government’s suspension policy which is expectedtook effect, Taiwan became a transshipment hub for the United States made polysilicon and ranked the third largest region in terms of China’s polysilicon import volume. The import volume from Germany and South Korea, the two largest countries in terms of China’s polysilicon import volume, has not been materially impacted due to remaina price commitment agreement between Wacker (a polysilicon manufacturer in effect inGermany) and the foreseeable future.Chinese government, and low AD and CVD tariffs imposed on major South Korean polysilicon manufacturers. In 2016, the polysilicon imported from Korea, Germany, Taiwan and the United States accounted for 50.0%, 25.4%, 9.2% and 4.9% of the total import volume, respectively.

Product mix

The proportion of our revenues that are generated from the sales of other photovoltaic products, also referred to as product mix, affects our revenues and profitability. In addition to the revenues generated from sales of polysilicon, we also generated revenues from other products. In 2010, we generated revenues from sales of modules and wafers and we processed wafers through tolling arrangements with third party wafer manufacturers. In 2011, we generated revenues from sales of wafers and modules we produced in our facilities. In 2012, we generated revenue from sales of modules for the first three quarters of the year before we sold 100% of our equity interests of Nanjing Daqo, and we also generated revenue from sales of wafers produced in our facilities. In 2013, 2014 and 2014,2015, we generated revenue from sales of polysilicon and wafers. For the year ended December 31, 2014,2016, the revenues we generated from our two segments included sales of polysilicon and wafers, which accounted for 69.9%73.1% and 30.1%26.9% of our total revenues from continuing operations, respectively.

Our production capacity and utilization

In the near future, we plan to continue to focus on our core businesses to further improve our operation efficiency, cost structure and products quality by expanding our capacity, adopting new technologies and optimizing the manufacturing processes. For our polysilicon business, we ramped up production at the Phase 1b1B facilities to their full annual capacity of 1,800 MT in 2010. We expanded the aggregate capacity of our Phase 1a1A and Phase 1b1B facilities to 4,300 MT through a capital enhancement project in 2011. In September 2012, we halted the production of polysilicon in our Phase 1a1A and 1b1B facilities in Chongqing and ultimately determined to cease production in the second quarter of 2013. In September 2012, we successfully completed our Xinjiang Phase 2a2A facilities. Currently our annual capacity in XinjiangAt the end of 2016, we completed the construction and installation of Phase 2a for polysilicon is 6,150 MT. We are3A and commenced initial production in the processfirst quarter of conducting our Phase 2b project to further increase2017. As of the polysilicondate of this annual report, we have achieved full production capacity. Our current annual capacity in our Xinjiang polysilicon facilities to 12,150is 18,000 MT. We are also considering further capacity expansion at our Xinjiang facilities in the medium term, which may be conducted in two stages, and expand total polysilicon production capacity to 25,000 MT by early 2017, subject to market and industry conditions.

For our wafer business, the Phase 1a1A wafer manufacturing facilities in Chongqing commenced commercial production in July 2011 and reached the current capacity of 36 million pieces in November 2011. We gradually increased the utilization rate of our wafer facilities in 2013 and successfully expanded the capacity to 72 million pieces in November 2013. In November 2015, we launched a wafer technology enhancement project at our Chongqing wafer facilities, which is expected to reduce our wafer manufacturing cost and increase our wafer capacity with a limited capital expenditure requirement. We upgraded our ingot furnaces from Generation 5 to Generation 6 directional solidification casting furnaces and increased our ingot output from approximately 500 kilograms per batch to approximately 800 kilograms per batch. We also increased our wafering capacity by improving efficiency of the existing wafering system and acquiring certain used wafering tools from the secondary market. By the end of the second quarter of 2016, we successfully completed this project and increased our annual wafer capacity from the 87 million pieces to approximately 100 million pieces.

Our production costs

Our polysilicon production costs consist primarily of the costs of electricity and other utilities, raw materials, labor and depreciation. Currently electricity is the largest component of our polysilicon production costs. In our Phase 2 facilities in Xinjiang, because of the abundant coal resources, the local electricity rate is much lower than that in most areas in China. This cost advantage, along with our operational expertise, enables us to become one of the lowest cost producers around the globe. We plan to implement additional measures to reduce our production costs through technology, process and equipment improvement. For example, we are in the process of conductingfully ramped up our Phase 2b2B project to further increaseat the end of the third quarter of 2015, which has increased the polysilicon production capacity in our Xinjiang facilities to 12,150 MT. We arehave also in the process of upgradingsuccessfully upgraded our off-gas treatment process from traditional Hydrogenation technology to Hydrochlorination technology. We expectAs a result, we managed to lower thereduce our production cost (including depreciation) and cash cost (excluding depreciation) to the level of $12 per $9.74/kg and $8.7 per $7.69/kg, respectively, when we fully ramp up capacity byin the endfourth quarter of 2015, a significant reduction compared to $12.98/kg and $10.60/kg as compared to the second quarter of 2015.2015 before we started to ramp up the Phase 2B project. In 2016, we continued our efforts to improve manufacturing efficiency and optimize production processes through several R&D and technology improvement projects in our Xinjiang polysilicon facilities. As a result, we achieved our best-ever cost structure with the production cost (including depreciation) of $8.66/kg and the cash cost (excluding depreciation) of $6.88/kg in the third quarter of 2016. Effective cost-reduction measures will have a direct impact on our financial condition and results of operations.

Our wafer production costs consist primarily of the costs of polysilicon, other raw materials, labor and depreciation.

Components of Results of Operations

Revenues

Our revenues are primarily derived from the sale of polysilicon and secondarily by the sale of wafers. In 2012,2014, the revenues we generated from the product sales of polysilicon, wafers and OEM services accounted for 69.9%, and 30.1% of our total revenues, respectively. In 2015, the revenues we generated from the product sales of polysilicon and wafers accounted for 84.6%69.2%, and 15.4%30.8% of our total revenues, respectively. In 2013,2016, the revenues we generated from the product sales of polysilicon and wafers accounted for 70.4%73.1% and 29.6%26.9% of our total revenues, from continuing operations, respectively. In 2014, the revenues we generated from the sales of polysilicon and wafers accounted for 69.9% and 30.1% of our total revenues from continuing operations, respectively. The percentage increase of the sales of wafers reflected improvements in the utilization rate and capacity of our wafer facilities. We plan to continue to focus on our current businesses to further improve operation efficiency, cost structure and product quality. If we are successful in executing our expansion plans, we expect our polysilicon revenue to grow in relation to our total consolidated revenues.

We commenced polysilicon production in 2008. We produced 3,3496,560 MT,⁽¹⁾, 4,805 9,771 MT and 6,56013,068 MT of polysilicon and sold 3,2625,972 MT^(2)(3)(1), 4,8238,234 MT⁽³⁾⁽¹⁾ and 5,97210,883 MT⁽³⁾⁽¹⁾of polysilicon in 2012, 20132014, 2015 and 2014,2016, respectively. Our polysilicon selling prices are directly affected by global supply and demand conditions. Due to the global oversupply of polysilicon since late 2008 and the resulting pricing pressure, the average selling price of our polysilicon decreased by 59.3% in 2012 as compared to 2011, further decreased by 23.3% in 2013 as compared to 2012, and increased by 34.4% in 2014 as compared to 2013.2013, decreased by 28.5% in 2015 as compared to 2014. In 2016, the fourth quarter of 2012, the sales prices for polysiliconannual average selling price was relatively stable and wafer both startedincreased by 0.9% as compared to recover from historical lows due to improved demand and reduced inventory levels, and continued to increase into the first half of 2014.2015.

We generated revenues of $86.9⁽²⁾$182.6 million, $109.0$182.0 million and $182.6 million from continuing operations in 2012, 2013 and 2014, respectively. We incurred net losses attributable to our shareholders of $111.9 million and $70.9$229.1 million in 20122014, 2015 and 2013,2016, respectively. We achieved net income attributable to our shareholders of $16.7 million, $13.0 million and $43.5 million in 2014. In 2012, our revenues from continuing operations included $73.5 million generated from sales of polysilicon2014, 2015 and $13.4 million generated from sales of wafers. In 2013, our revenues from continuing operations included $76.7 million generated from sales of polysilicon and $32.3 million generated from sales of wafers.2016, respectively. In 2014, our revenues from continuing operations included $127.7 million generated from sales of polysilicon and $54.9 million generated from sales of wafers. In 2015, our revenues included $125.9 million generated from sales of polysilicon and $56.1 million generated from sales of wafers. In 2016, our revenues included $167.5 million generated from sales of polysilicon and $61.6 million generated from sales of wafers.

We have entered into framework agreements with some of our customers. These contracts typically contain binding terms related to the sales volumes of our photovoltaic products during the contract term. The pricing terms are typically agreed upon between us and our customers based on the prevailing market prices when specific sales orders are placed. Such pricing determination method has caused, and is expected to continue to cause, fluctuations in our revenues and results of operations. In 2012, our top three customers, Yingli Green Energy, Solargiga and Jiangxi Sornid, accounted for approximately 25.0%, 8.6% and 7.3% of our total revenues, respectively, and the three customers in aggregate accounted for approximately 40.9% of our total revenues. In 2013, our top three customers, Jiangsu Meike Silicon Energy, Zhenjiang Daqo and Hanwha SolarOne , accounted for approximately 18.0%, 12.4% and 8.1% of our total revenues, respectively, and the three customers in aggregate accounted for approximately 38.5% of our total revenues. In 2014, our top three customers, Jiangsu Meike Silicon Energy, JA Solar Technology Yangzhou Co., Ltd., and Jinko Solar Co., Ltd., accounted for approximately 13.1%, 10.0% and 9.0% of our total revenues, respectively, and the three customers in aggregate accounted for approximately 32.1% of our total revenues. In 2015, our top three customers, Jinko Solar, Jinneng Clean Energy and Meike Silicon Energy, accounted for approximately 19.3%, 11.2% and 10.0% of our total revenues, respectively, and the three customers in aggregate accounted for approximately 40.5% of our total revenues. In 2016, our top three customers, Jinko Solar Meike Silicon Energy and Konca Solar, accounted for approximately 21.3%,8.6% and 7.3% of our total revenues, respectively, and the three customers in aggregate accounted for approximately 37.1% of our total revenues.

Notes:Note:

Cost of revenues

Our cost of revenues primarily consists of:

Due to our capacity expansion, depreciation in absolute terms had increased significantly prior to 2014. Depreciation in absolute terms has decreased significantly in 2014, primarily as a result of our revision to the expected useful lives of fixed assets during the first quarter of 2014 and the deconsolidation of our former variable interest entity as of December 30, 2013. Nevertheless,Along with the full ramp-up of Phase 2B polysilicon expansion project since August 2015, the depreciation willin absolute terms increased significantly in 2015 and 2016 due to higher production volume. Depreciation would resume its upward trend if we were to further expand our polysilicon production capacity or conduct technology improvement as we currently plan to do.improvement. We also expect that our total cost of revenues will increase as we increase our sales volume.

Operating expenses/income

Our operating expenses include selling, general and administrative expenses and research and development expenses, which are partially offset by other operating income as described below.

Selling, general and administrative expenses

Our selling, general and administrative expenses consist primarily of salaries and benefits for our administrative, finance and sales personnel, packaging and shipping costs, sales-related travel and entertainment expenses, other travel and corporate expenses, depreciation of equipment used for administrative purposes and professional expenses. All costs in connection with start-up activities, including costs incurred prior to commencement of production and corporate formation costs of Daqo Cayman, were expensed as incurred. We expect that the amount of our selling, general and administrative expenses will increase as we expand our polysilicon production capacity, increase our sales efforts, hire additional personnel, and incur professional expenses to support our operations as a listed company in the United States.

Research and development expenses

Our research and development expenses consist primarily of costs of raw materials used in research and development activities, salaries and employee benefits for research and development personnel, and equipment costs relating to the design, development, testing and enhancement of our production process. We expect our research and development expenses to increase in the future as we continue to hire additional research and development personnel and focus on improvement of process technologies for our products, and expand our polysilicon manufacturing business. In the fourth quarter of 2012, we incurred additional research and development expenses for our Xinjiang Phase 2 polysilicon facilities to achieve the targets for product quality, capacity and cost during the pilot production period, which are not expected to recur. Our research and development expenses in 20132014, 2015 and 20142016 primarily resulted from continuous technology improvement projects for polysilicon and wafer production.

Other operating income

Our other operating income reflects unrestricted government subsidies that we receive from time to time, including financial incentives from Chongqing and Xinjiang local government, which are unrestricted as to use and can be utilized by us in any manner we deem appropriate. We have utilized, and expect to continue to utilize, these subsidies to fund general operating expenses. We record unrestricted government subsidies as other operating income when we receive them. The amount and timing of subsidies cannot be predicted with certainty.

Fixed asset impairment loss

We recognized $42.8$158.4 million impairment loss for the long-lived assets of our wafer facilities in 2012 and $158.4 million for the long-lived assets of our polysilicon facilities in 2013. The impairment loss of long-lived assets of our wafer and polysilicon facilities recognized in 2012 and 2013 reflected the impact of year-on-year market challenges and in particular reductions in average selling prices of our products in those yearsthat year as described above, without similar reductions in costs of production, that have had an adverse effect on the profit-generating ability of these assets. No impairment loss of long-lived assets was recognized in 2014. We recognized an impairment loss of $1.6 million and $0.2 million in 2015 and 2016, respectively, which was related to certain identified relocation assets in Chongqing that were not transferrable and could not be reutilized in our Xinjiang expansion project.

Interest income and expense

Our interest income represents interest on our cash balances. Our interest expenses relate primarily to our short-term and long-term borrowings from banks, less capitalized interest expenses to the extent they relate to our capital expenditures.

Taxation

Cayman Islands tax

We are an exempted company incorporated in the Cayman Islands and are not subject to tax in this jurisdiction.

PRC tax

Our Chinese subsidiaries are foreign invested enterprises in China. Under the EIT Law which took effect as of January 1, 2008, the Chinese enterprise income tax rate is 25%. However, qualified enterprises located in central or western China may enjoy preferential tax rate under a series of national policies adopted to encourage investment in central and western China.

Under the EIT Law, an enterprise established outside of China with its “de facto management bodies” within China may be considered a resident enterprise for Chinese tax purposes and be subject to the enterprise income tax at the rate of 25% on its global income. The implementation rules of the EIT Law provide that the term “de facto management bodies” refers to management bodies which have material management and control over all aspects of the business, including production, operations, personnel, finance, and assets. It is unclear whether Chinese tax authorities would determine that, notwithstanding our status as the Cayman Islands holding company of our operating business in China, we should be classified as a resident enterprise. Currently, substantially all of our income is already China-source income subject to Chinese taxes. However, a portion of the net proceeds received from our initial public offering were deposited into interest bearing bank accounts.

Chongqing Daqo, our wholly owned Chinese subsidiary and a foreign-invested enterprise established in the central and western region in China, is entitled to a preferential income tax rate of 15% from the date of its establishment to December 31, 2010. Chongqing Daqo is qualified as a “Chongqing Municipality High and New Technology Enterprise,” which entitles it to a preferential income tax rate of 15%. Chongqing Daqo received its first qualification in November 2009 for a three-year period. The status was renewed in November 20122015 for an additional three years until November 20152018 and the status can be renewed for additional three-year terms upon Chongqing Daqo’s application and the government’s approval. In November 2014, Xinjiang Daqo, another wholly owned Chinese subsidiary, obtained “High and New Technology Enterprise” certificate for a valid period of three years till 2016, which entitles it to enjoy the preferential income tax rate of 15%.

Daqo New Material, formerly our consolidated variable interest entity and a domestic Chinese enterprise, was, during 2013, subject to an income tax rate of 25%. Starting from December 31, 2013, Daqo New Material was de-consolidated from the balance sheet as of December 31, 2013.

Under the EIT Law and implementation regulations issued by the State Council of China, dividends, interests, rent, royalties and gains on transfers of property payable by a foreign-invested enterprise in China to its foreign investor who is a non-resident enterprise will be subject to a 10% withholding tax, unless such non-resident enterprise’s jurisdiction of incorporation has a tax treaty with China that provides for a reduced rate of withholding tax and such non-resident enterprise is the beneficial owner of the dividends, interests, rent, royalties and gains on transfers of property. The Cayman Islands, where Daqo Cayman is incorporated, does not have such a tax treaty with China. However, we intend to reinvest all of Chongqing Daqo’s undistributed earnings into our capacity expansion and/or technology improvement and do not plan to distribute any of the earnings as dividends in the foreseeable future and, accordingly, we have not set aside provision for Chinese dividend withholding tax. If we do distribute these earnings in the form of dividends, we will be subject to the withholding tax at a rate of 10%.

Pursuant to the Interim Regulations on Value Added Tax and their implementation rules, all entities and individuals that are engaged in the sale of goods, the provision of repairs and replacement services or the importation of goods in China are generally required to pay value-added tax, or VAT, at a rate of 17% of the gross sales proceeds received, less any deductible VAT already paid or borne by the taxpayer. When exporting certain goods, excluding polysilicon currently, the exporter is entitled to VAT refund, which amount will be a portion of or all of the VAT that it has already paid or borne. For our sales of polysilicon products, we are subject to the 17% VAT without any VAT refunds for such sales.

Critical Accounting Policies

We prepare our consolidated financial statements in accordance with U.S. GAAP, which requires us to make judgments, estimates and assumptions that affect (1) the reported amounts of assets and liabilities, (2) disclosure of contingent assets and liabilities at the end of each reporting period, and (3) the reported amounts of revenues and expenses during each reporting period. We continually evaluate these estimates and assumptions based on historical experience, knowledge and assessment of current business and other conditions, and expectations regarding the future based on available information and reasonable assumptions, which together form a basis for making judgments about matters not readily apparent from other sources. Since the use of estimates is an integral component of the financial reporting process, actual results could differ from those estimates. Some of our accounting policies require higher degrees of judgment than others in their application. When reviewing our financial statements, you should consider (1) our selection of critical accounting policies, (2) the judgment and other uncertainties affecting the application of such policies, and (3) the sensitivity of reported results to changes in conditions and assumptions. We consider the policies discussed below to be critical to an understanding of our financial statements as their application places the most significant demands on the judgment of our management.

Property, plant and equipment

We reassess the reasonableness of the estimates of useful lives and residual values of long-lived assets when events or changes in circumstances indicate that the useful lives and residual values of a major asset or a major category of assets may not be reasonable. Factors that we consider in deciding when to perform an analysis of useful lives and residual values of long-lived assets include, but are not limited to, significant variance of a business or product line in relation to expectations, significant deviation from industry or economic trends, and significant changes or planned changes in the use of the assets. The analysis will be performed at the asset or asset category with reference to the assets’ conditions, current technologies, market, and future plan of usage and the useful lives of major competitors.

In 2013, we made the decision to relocate a majority of our polysilicon assets in Chongqing to Xinjiang. As part of the decision to make significant investment to relocate the assets, we revisited the expectation as to the useful lives of these assets. Based on this review, we determined that the condition of our major assets, having now been in operation for a meaningful percentage of the original estimated lives, were in a better condition than the original useful life expectation had predicted. Accordingly, we engaged an independent valuation firm to assist in reassessing the remaining economic useful life of the polysilicon assets in both Chongqing and Xinjiang. The analysis was completed in the first quarter of 2014.

Therefore, we revised the estimates of expected useful lives of long-lived assets from January 1, 2014. The useful lives of machinery and equipment were expanded from 10 years to 15 years, while the useful lives of buildings and structures were expanded from 20 years to 30 years. No changes were made to furniture, fixtures and equipment, or motor vehicles.

Revenue recognition

We generate revenues primarily from the sale of polysilicon and wafer and recognize revenues when all of the following conditions are met: persuasive evidence of an arrangement exists, the sales price is fixed and determinable, delivery of the products has occurred, title and risk of loss have transferred to customers and collectability of receivable is reasonably assured. Our polysilicon sales agreements with our customers typically do not contain product warranties except for return and replacement of defective products within a period ranging from 3 to 30 days from delivery. In addition, our agreements do not contain post-shipment obligations or any other return or credit provisions.

A majority of our sales contracts provide that title and risk of loss related to the products are transferred to our customers upon receipt. We may extend credit terms to our customers after assessing a number of factors to determine their credit worthiness.

Allowance for doubtful accounts

We conduct credit reviews for customers to whom we extend credit terms. We estimate the amount of accounts receivable that may not be collected based on the aging of our accounts receivable and specific evidence relating to the financial condition of our customers that may affect their ability to pay their balances.

Impairment of long-lived assets

We evaluate our long-lived assets and finite-lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. Factors that we consider in deciding when to perform an impairment review include, but are not limited to significant under-performance of a business or product line in relation to expectations, significant negative industry or economic trends, and significant changes or planned changes in the use of the assets. An impairment analysis is performed at the lowest level of identifiable independent cash flows for an asset or asset group. We make subjective judgments in determining the independent cash flows that can be related to a specific asset group based on the asset usage model and manufacturing capabilities. We measure the recoverability of assets that will continue to be used in the operations by comparing the carrying value of the asset group to the estimate of the related total future undiscounted cash flows. If an asset group’s carrying value is not recoverable through the related undiscounted cash flows, the impairment loss is measured by comparing the difference between the asset group’s carrying value and its fair value. We determine the fair value of an asset or asset group utilizing estimated future discounted cash flows and incorporate assumptions that it believes marketplace participants would utilize. The impairment charges for the years ended December 31, 20122014, 2015 and 20132016 were $42.8nil, $1.6 million $158.4and $0.2 million, respectively, and we did not recognize any impairment charges for the year ended December 31, 2014. The impairment loss incurred in fiscal year 2012 was related to the impairment of long-lived assets of the wafer business, and was triggered primarily by the significant decrease in average selling prices for wafers that was experienced in 2012. In 2013, the impairment loss was related to the impairment of long-lived assets of the polysilicon facilities in Chongqing. As a result of certain difficulties in obtaining the planned reductions in cost at the Phase 1 polysilicon facilities, combined with the plan to expand capacity at our Xinjiang plant, we concluded that the best course of action was to (i) cease production at the Phase 1 polysilicon facilities, after which we incurred an impairment charge of $158.4 million in the second quarter of 2013 and (ii) relocate machinery and equipment from the Phase 1 polysilicon facilities to Xinjiang. In 2013, we evaluated under ASC 360-10-35-21 whether there were events or changes in circumstances which indicated that the carrying amount of our wafer asset group may not be recoverable. We concluded that there existed the triggering event due to the continuing decrease of average selling prices in 2013, and performed the recoverability test, with the estimate of future cash flows by using certain significant assumptions such as the estimated future selling prices of wafer, production costs, and projected sales volumes. We estimated such significant assumptions with reference to the historical records, industry analysis reports, current indications of customer demand and the management’s experience. As a result, we concluded the estimated sum of the undiscounted cash flows expected to result from the use and eventual disposition of the wafer asset group substantially exceeded the carrying amount, and no impairment was noted as of December 31, 2013.respectively. In August 2014, our board of directors approved the launch of an early stage research of the Phase 3 expansion in our Xinjiang polysilicon facilities. After a comprehensive analysis of the capacity and comparability of the Chongqing machinery and equipment, we concluded that it would be more efficient to use part of the machinery and equipment in Phase 3, rather than using all of them in Phase 2 project. The change to the relocation plan indicated that the carrying amount of our polysilicon asset group may not be recoverable. We performed the technology feasibility and economic viability research, and the recoverability test, with the estimate of future cash flows by using certain significant assumptions, such as the estimated future selling prices of polysilicon, production costs and projected sales volumes. We estimated such significant assumptions with reference to the historical records, industry analysis reports, current indications of customer demand and management’s experience. As a result, we concluded that the estimated sum of the undiscounted cash flows expected to be generated from the use and eventual disposition of the polysilicon group were in substantial excess of the carrying amount, and no impairment was noted as of December 31, 2014. The impairment loss of $1.6 million and $0.2 million incurred in 2015 and 2016, respectively, were related to certain identified relocation assets in Chongqing that were not transferrable and could not be reutilized in our Xinjiang expansion project. Regarding the wafer asset group, there was no impairment indicator noted as of December 31, 2014.2014, 2015 and 2016.

As of the end of 2014, a total of 1,549,163 options have been forfeited due to grantees’ departure from our company and a total of 639,187 options have expired.

We recognize share-based compensation in the statement of operations based on the fair value of equity awards on the date of the grant, with compensation expense recognized over the period in which the grantee is required to provide service to us in exchange for the equity award. We have made an estimate of expected forfeiture and is recognizing compensation costs only for those equity awards to vest. The share-based compensation expenses have been classified as either selling, general and administrative expenses or research and development expenses, depending on the job functions of the grantees.

With respect to options granted on October 6, 2010, December 3, 2010, January 9, 2012, April 3, 2013, January 28, 2014, and January 12, 2015 and July 6, 2015, we estimated the fair value of share options granted using the binomial option pricing model with the assistance of the independent appraiser, which requires the input of highly subjective assumptions, including the expected life of the share options, estimated forfeitures and the price volatility of the underlying shares. The assumptions used in calculating the fair value of share options represent management’s best estimates. As a result, if factors change and we use different assumptions, our share-based compensation expense could be materially different in the future. In addition, we estimate our expected forfeiture rate and recognize the expense only for those shares expected to vest. These estimates are based on past employee-retention rates. We will prospectively revise our estimated forfeiture rates based on actual history. Our compensation expense may change based on changes to our actual forfeitures of these share options.

Results of Operations

The following table sets forth a summary of our consolidated statements of operations for the periods. Our historical results presented below are not necessarily indicative of the results that may be expected for any future period.

Year Ended December 31, 20142016 Compared to Year Ended December 31, 2013 for Continuing Operations2015

Total revenues. Our total revenues increased by 67.5%25.9% from $109.0$182.0 million in 20132015 to $182.6$229.1 million in 2014. The increase in total revenues was primarily attributable to higher sales volumes, as well as higher average selling prices in both polysilicon and wafers.2016.

Revenue from Polysiliconproduct sales of polysilicon.The revenue derived from product sales of polysilicon increased from $76.7was $167.5 million in 2013 to $127.72016, representing an increase of 33.0% from $125.9 million in 2014. The improvement2015. All of revenue of $51.0 million was primarily contributed by the impact of higher sales volumes and higher selling prices of $29.2 million and $20.8 million,⁽¹⁾ respectively. The polysilicon sold in 2013 and 20142016 was mostlymanufactured in our Xinjiang facilities, whereas most of the polysilicon sold in 2015 was contributed by our Xinjiang facilities. We ramped up the production capacity of 5,000 MT at Phase 2a facilities in Xinjiang in March 2013 and further increased our production capacity to 6,150 MT in the first quarter of 2014. As a result of the upgrade of the manufacturing process and improvement in our production efficiency at our Xinjiang facilities, our actual polysilicon production reached 1,748 MT duringDuring the third quarter of 2014, exceeding2015, we successfully ramped up our Phase 2B expansion project, which increased our annual capacity from 6,150 MT nameplate capacity by 9.0%. Accordingly,to 12,150 MT. During the whole year of 2016, we were running our Xinjiang polysilicon facilities at full capacity. As a result, our annual polysilicon production volume increased by 36.5%33.7% from 9,771 MT in 2014, as compared2015 to 2013. Our13,068 MT in 2016. Accordingly, our external polysilicon sales volume increased by 32.2% from 8,234 MT in 2015 to 10,883 MT in 2016. Moreover, our annual polysilicon average selling price for polysiliconprices also improved slightly from $15.29/kg in 2014 was higher than 2013, increased by 34.4%.2015 to $15.42/kg in 2016.

Note:

Revenue from Wafersproduct sales of wafers.. The revenue derived from the sales of wafers increased from $32.3were $61.6 million in 2013 to $54.92016, an increase of 9.7% from $56.1 million in 2014,2015. Wafer sales volume was 82.8 million pieces, an increase of 8.3% from 76.4 million pieces in 2015. The increase in wafer revenues as compared to 2015 was primarily due to higher sales volume as a result of the capacity fully ramped up from 36 million pieces to 72 million pieces in November 2013. Our wafer utilization rate also improved significantly in 2014 compared to 2013.volume.

Total Cost of revenues. Our cost of revenues increased by 3.1%2.9% from $135.1$144.5 million in 20132015 to $139.3$148.7 million in 2014.2016.

Cost of revenue from Polysiliconproduct sales of polysilicon. The cost of ourrevenue from product sales of polysilicon revenue was $91.4$96.3 million in 2014.2016, including $6.9 million in idle cost related to Chongqing polysilicon facility. Although our polysilicon productionexternal sales volume increased by 36.5%33.7% from 9,771 MT in 2014 compared2015 to 2013,13,068 MT in 2016, our cost of revenue from product sales of polysilicon just increaseddecreased by 7.0% compared to $85.51.4% from $97.7 million in 2013 due2015 to our$96.3 million in 2016, as a result of the significant cost reduction effort, the success of our Phase 2B expansion and several technology improvement projects, which further reduced our production cost in our Xinjiang facilities, as well as to the decrease in depreciation expenses of $23.9 million attributable to the revision to the expected useful lives of fixed assets in the amount of $18.7 million and the deconsolidation of our former variable interest entity in the amount of $5.2 million.facilities.

Cost of revenue from Wafersproduct sales of wafers. The cost of ourrevenue from product sales of wafers revenue decreasedincreased by 3.5%12.1% from $49.6$46.8 million in 20132015 to $47.9$52.4 million in 2014.2016. The decreaseincrease was primarily due to higher sales volume partially offset by a lower unit production cost partially offsetting by higher production volume in 2014. In November 2013, we fully ramped up our wafer facilities to a capacity of 72 million pieces per annum. Our wafer production volume increased by 2 times in 20142016 as compared to 2013.2015.

Gross (loss) profit. We had a gross profit of $43.3$80.4 million in 2014,2016, an increase of 114.2% from $37.6 million in 2015. Gross margin was 35.1% in 2016, compared to loss of $26.1 million20.6% in 2013. Our gross margin was 23.7% in 2014, compared to negative 23.9% in 2013.2015. The improvement in gross profit and gross margin from 2013 was primarily attributable to our polysilicon sector due to improved cost structures in polysilicon, as well as higherthe slight increase of average selling prices.prices and further decrease of unit cost mentioned above.

Gross (loss) profit from Polysiliconproduct sales of polysilicon. OurExcluding the idle cost related the Chongqing polysilicon facility, our polysilicon business had a gross profit of $36.2$78.2 million in 2014, compared to loss2016, representing an increase of $8.8100.9% from $38.9 million in 2013. Our2015. In 2016, we successfully reduced our annual polysilicon business’s gross margin was 28.4%total production cost by 17.8% from $11.23/kg in 2014, compared2015 to negative 11.5%$9.38/kg in 2013. The improvement2016 and increased our polysilicon external sales volume by 33.7% from 9,771 MT in gross profit and gross margin from 2013 was primarily due2015 to improved cost structures, as well as higher13,068 MT in 2016. Moreover, our annual polysilicon average selling prices.price also improved slightly from $15.29/kg in 2015 to $15.42/kg in 2016.

Gross (loss) profit from Wafersproduct sales of wafers. Our wafer business had a gross profit of $7.0$9.2 million in 2014,2016, representing a decrease of 2.2% from $9.4 million in 2015.
