BASIS OF PRESENTATION AND NATURE OF OPERATIONS
BASIS OF PRESENTATION AND NATURE OF OPERATIONS	NOTE 1—BASIS OF PRESENTATION AND NATURE OF OPERATIONS Basis of Presentation These consolidated financial statements reflect the financial statements of STR Holdings, Inc. ("Holdings" or the "Company") and its subsidiaries on a consolidated basis. Due to the divestiture of the Quality Assurance ("QA") business as discussed below, the QA business' historical operating results are recorded in discontinued operations in the Consolidated Statements of Comprehensive Loss and Consolidated Statements of Cash Flows for all applicable periods presented. See Note 4 below. On January 30, 2015, the Company filed a Certificate of Amendment to its Restated Certificate of Incorporation in order to effect a one-for-three reverse split of its common stock and its common stock began trading on the New York Stock Exchange ("NYSE") on a split-adjusted basis on February 2, 2015. No fractional shares were issued in connection with the reverse stock split. As a result of the reverse stock split, the number of issued and outstanding shares of the Company's common stock was reduced to approximately 18,074,291 and 18,073,051, respectively, at December 31, 2014. The change in the number of shares resulting from the reverse stock split has been applied retroactively to all shares and per share amounts presented in the consolidated financial statements and accompanying notes. On September 29, 2015, the Company was notified by the NYSE that the Company was not in compliance with the continued listing standards set forth in Section 802.01B of the NYSE Listed Company Manual due to the Company's failure to maintain an average global market capitalization over a consecutive 30 trading-day period of at least $15,000. The Company's common stock began trading on the OTC Pink Marketplace beginning on September 30, 2015 under the ticker symbol "STRI." On October 5, 2015, the Company's common stock began trading on the OTCQX Marketplace under the symbol "STRI." The accompanying consolidated financial statements and the related information contained within the notes to the consolidated financial statements have been prepared in accordance with Generally Accepted Accounting Principles ("GAAP") in the United States of America and applicable rules and regulations of the Securities and Exchange Commission ("SEC") for financial information and annual reports on the Form 10-K. Nature of Operations The Company was incorporated in 1944 as a plastics and industrial materials research and development company and evolved into two core businesses: solar encapsulant manufacturing and quality assurance services. The Company currently designs, develops and manufactures encapsulants that protect the embedded semiconductor circuits of solar panels and sells these products to solar module manufacturers worldwide. The Company launched its former QA business in 1973 and commenced sales of solar encapsulant products in the late 1970s. The Company's strategic divestiture of the QA business is described below and in Note 4.

SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2015
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 2—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES A summary of the Company's significant accounting policies is as follows: Basis of Accounting. The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America. Principles of Consolidation. The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. Intercompany transactions and account balances have been eliminated. Use of Estimates. The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires the Company to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and the accompanying notes. The Company's significant estimates include its revenue recognition, allowance for doubtful accounts receivable, inventory valuation, the recorded amounts and amortization periods of its intangible assets, valuation of goodwill and long-lived assets, product performance accrual, income taxes payable, deferred income taxes, its assessment of uncertain tax positions and its valuation of stock-based compensation costs. Actual results could differ materially from these estimates. Fair Value Estimates. Accounting Standards Codification ("ASC") 820-10 Fair Value Measurements defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820-10 classifies the inputs used to measure fair value into the following hierarchy: Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities Level 2: Unadjusted quoted prices in active markets for similar assets or liabilities, or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability Level 3: Unobservable inputs for the asset or liability The carrying values for cash, accounts receivable, income tax receivable, accounts payable, accrued liabilities, income taxes payable and other current assets and liabilities approximate their fair values due to their short maturities. The carrying value of the Company's money market funds is based on the balance of its money market funds as of December 31, 2015, which is a Level 1 input. The carrying value of deferred compensation in 2014, which is a Level 2 input, was based upon the effective valuation of the transaction with Zhenfa of $4.80 per share. See Note 14. Foreign Currency Translation and Transactions. The Company's international operations use the local currency as their functional currency, except for its Malaysian subsidiary whose functional currency is the U.S. dollar. Assets and liabilities of international operations are translated at period-end rates of exchange; revenues and expenses are translated at average rates of exchange. The resulting translation gains or losses are reflected in accumulated other comprehensive loss. Gains or losses resulting from foreign currency transactions are included in net loss. Cash and Cash Equivalents. All highly-liquid investments with a maturity of three months or less at the date of purchase are considered to be cash equivalents. The Company deposits its cash balances with a limited number of banks. Cash balances in these accounts generally exceed government insured limits. Recognition of Revenue and Accounts Receivable. The Company recognizes revenue net of any sales returns and allowances when evidence of an arrangement exists, delivery of the product or service has occurred and title and risk of loss have passed to the customer, the sales price is fixed or determinable, and collectability of the resulting receivable is reasonably assured. The Company recognizes revenue from the manufacture and sale of its encapsulants, which is the only contractual deliverable, either at the time of shipping or at the time the product is received at the customer's port or dock, depending upon terms of the sale. The Company does not offer a general right of return on its products. On isolated occasions, the Company has offered limited short-term performance warranties relating to its encapsulants not causing module power loss. The Company's encapsulants are validated by long-term performance testing during product development prior to launch and during customer certification prior to mass production. The Company has operated its solar business since the 1970s and over 20 GW of solar modules incorporating its encapsulants have been installed in the field with no reported module power performance issues caused by its encapsulants and no related warranty claims to-date. Based on this fact pattern, the Company has not accrued any warranty liability associated for this potential liability as its occurrence is deemed to be remote. If the Company were to ever receive a warranty claim for such matter, it would assess the need for a warranty accrual at that time. Allowance for Doubtful Accounts. The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. The Company reviews the collectability of its receivables on an ongoing basis and writes off accounts receivable after reasonable collection efforts have been made and collection is deemed uncollectible. Inventories. The Company's inventories are stated at the lower of cost or market. The Company's primary raw materials consist of resin, paper, packaging material and chemicals/additives. The Company's finished goods inventories are typically made-to-order and possess a shelf life of six to nine months from the date of manufacture. Cost is determined on a first-in, first-out basis and includes both the costs of acquisition and the costs of manufacturing. These costs include direct material, direct labor and fixed and variable indirect manufacturing costs, including depreciation expense. The Company will write down inventory to its net realizable value when it is probable that the inventory carrying cost is not fully recoverable through sale or other disposition. The Company's write-down considers overall market conditions, customer inventory levels, legal or contractual provisions and age of the inventories. In 2015, the Company reserved $696 of inventory, a majority of which was related to excess raw material and expired finished goods inventory. In 2014, the Company reserved $1,025 of inventory, a majority of which was related to excess raw material and expired finished goods inventory related to recent product introductions. Long-Lived Assets. The Company's long-lived assets consist of property, plant and equipment. Property, plant and equipment are recorded at cost and include expenditures for items that increase the useful lives of existing equipment. Maintenance and repairs are expensed as incurred. Property, plant and equipment accounts are relieved at cost, less related accumulated depreciation, when properties are disposed of or otherwise retired. Gains and losses from disposal of property, plant and equipment are included in net loss. In accordance with ASC 360—Property, Plant, and Equipment, the Company reviews the carrying value of its long-lived assets, including property, plant and equipment, for impairment when events or changes in circumstances indicate the carrying value of an asset may not be recoverable. If a long-lived asset is found to be impaired, the amount recognized for impairment is equal to the difference between the carrying value and the asset's fair value. Fair value is estimated based upon discounted future cash flows, appraisals or other reasonable estimates of fair market value. Asset Retirement Obligations. The Company accounts for asset retirement obligations in accordance with ASC 410—Asset Retirement and Environmental Obligations, which requires a company to recognize a liability for the fair value of obligations to retire tangible long-lived assets when there is a contractual obligation to incur such costs. The Company has recorded its asset retirement obligations relating to the cost of removing improvements from lease facilities at the end of the lease terms. The Company's conditional asset retirement obligations are not material. Leases. The Company leases certain facilities and equipment used in its operations. The Company accounts for its leases under the provisions of ASC 840—Leases, which requires that leases be evaluated and classified as operating or capital leases for financial reporting purposes. Operating lease expense is recorded on a straight-line basis over the lease term. Income Taxes. The Company accounts for income taxes using the asset and liability method in accordance with ASC 740—Income Taxes. Under this method, the Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and for operating loss and tax credit carryforwards. The Company estimates its deferred tax assets and liabilities using the enacted tax laws expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled, and will recognize the effect of a change in tax laws on deferred tax assets and liabilities in the results of its operations during the period that includes the enactment date. The Company records a valuation allowance to reduce its deferred tax assets if it determines that it is more likely than not that some or all of the deferred tax assets will not be realized. The Company operates in multiple taxing jurisdictions and is subject to the jurisdiction of a number of U.S. and non-U.S. tax authorities and to tax agreements and treaties among those authorities. Operations in these jurisdictions are taxed on various bases in accordance with jurisdictional regulations. Tax benefits related to uncertain tax positions taken or expected to be taken on a tax return are recorded when such benefits meet a more likely than not threshold. Otherwise, these tax benefits are recorded when a tax position has been effectively settled, which means that the appropriate taxing authority has completed their examination even though the statute of limitations remains open or the statute of limitation expires. Interest and penalties related to uncertain tax positions are recognized as part of the Company's provision for income taxes and are accrued beginning in the period that such interest and penalties would be applicable under relevant tax law until such time that the related tax benefits are recognized. See Note 16. Factoring Arrangement. The Company has entered into a factoring agreement to sell, with recourse, certain European, U.S. and other foreign company-based receivables to Eurofactor Hispania S.A.U. The Company receives funds from the factor for certain outstanding receivables for which the Company records a liability. Once the customer pays the factor directly for those receivables the Company clears the accounts receivable and the liability. As of December 31, 2015 the Company has recorded $483 as due to factoring on the consolidated balance sheets. See Note 15. Product Performance Accrual. The Company provides a short-term warranty that it has manufactured its products to the Company's specifications. On limited occasions, the Company incurs costs to service its products in connection with specific product performance matters that do not meet the Company's specifications. Anticipated future costs are recorded as part of cost of sales and accrued liabilities for specific product performance matters when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated. On isolated occasions, the Company has offered limited short-term performance warranties relating to its encapsulants not causing module power loss. The Company's encapsulants are validated by long-term performance testing during product development prior to launch and during customer certification prior to mass production. The Company has operated its solar business since the 1970s and over 20 GW of solar modules incorporating its encapsulants have been installed in the field with no reported module power performance issues caused by its encapsulants and no related warranty claims to date. Based on this fact pattern, the Company has not accrued any warranty liability associated for this potential liability as its occurrence is deemed to be remote. If the Company were to ever receive a warranty claim for such matter, it would assess the need for a warranty accrual at that time. Cost of Sales. The Company includes the cost of inventory sold and related costs for the distribution of its product in cost of sales. These costs include raw materials and other components, direct labor, product performance matters, manufacturing overhead, salaries, and other personnel-related expenses, write-off of inventory, quality control, freight, insurance and depreciation. Shipping and handling costs are classified as a component of cost of sales. Customer payments for shipping and handling costs are recorded as a component of net sales. Selling, General and Administrative Expenses. Selling, general and administrative expenses consist primarily of salaries, travel, commissions and other personnel-related expenses for employees engaged in sales, marketing and support of the Company's products and services, trade shows and promotions. General and administrative expenses consist of expenses for the Company's finance, administrative, information technology, compliance and human resource functions. Research and Development Expense. The Company's research and development expense consists primarily of salaries and fringe benefit costs and the cost of materials and outside services used in its pre-commercialization process and development efforts. The Company records depreciation expense for equipment that is used specifically for research and development activities. Stock-Based Compensation. In accordance with ASC 718—Compensation-Stock Compensation, the Company recognizes the grant date fair value of stock-based awards granted to employees as compensation expense over the vesting period of the awards. See Note 18. Loss Per Share. The Company computes basic loss per common share in accordance with ASC 260—Earnings Per Share. Under the provisions of ASC 260, basic net loss per common share is computed by dividing the net loss available to common stockholders by the weighted-average common shares outstanding during the period. Diluted net loss per common share adjusts basic net loss per common share for the effects of stock options and restricted stock awards only in periods in which such effect is dilutive. See Note 5. Comprehensive Loss. Comprehensive loss consists of net loss and the effects on the consolidated financial statements of translating the financial statements of the Company's international subsidiaries. Comprehensive loss is presented in the consolidated statements of comprehensive loss. The Company's accumulated other comprehensive loss is presented as a component of equity in its consolidated balance sheets and consists of the cumulative amount of the Company's foreign currency translation adjustments, net of tax. Recent Accounting Pronouncements: In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, "Revenue from Contracts with Customers" (Topic 606). This ASU is intended to clarify the principles for recognizing revenue by removing inconsistencies and weaknesses in revenue requirements; providing a more robust framework for addressing revenue issues; improving comparability of revenue recognition practices across entities, industries, jurisdictions and capital markets; and providing more useful information to users of financial statements through improved revenue disclosure requirements. The provisions of this ASU are effective for interim and annual periods beginning after December 15, 2016. On August 12, 2015, the FASB issued ASU 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date," which delays the effective date of ASU 2014-09 by one year. The new standard is effective for reporting periods beginning after December 15, 2017. Early application is permitted for reporting periods beginning after December 15, 2016. The Company is currently evaluating the new guidance to determine the impact it may have to its consolidated financial statements. In February 2015, the FASB issued ASU No. 2015-02, "Consolidation (Topic 810) Amendments to the Consolidation Analysis." The amendments contained in this update affect reporting entities that are required to evaluate whether they should consolidate certain legal entities. All legal entities are subject to reevaluation under the revised consolidation model. The amendments in this update affect limited partnerships and similar legal entities, evaluating fees paid to a decision maker or a service provider as a variable interest, the effect of fee arrangements on the primary beneficiary determination, the effect of related parties on the primary beneficiary determination and certain investment funds. This ASU is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. The Company is currently evaluating the new guidance to determine the impact it may have to its consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, "Simplifying the Measurement of Inventory." This ASU changes the measurement principle for inventory from the lower of cost or market to lower of cost and net realizable value. Net realizable value is defined as the estimated selling prices in the ordinary course of business; less reasonably predictable costs of completion, disposal and transportation. The provisions of this ASU are effective for years beginning after December 15, 2016. The Company is currently evaluating the new guidance to determine the impact it may have to its consolidated financial statements. In November 2015, the FASB issued ASU 2015-17, "Balance Sheet Classification of Deferred Taxes." This ASU simplifies the presentation of deferred income taxes. The amendments in this update require that deferred tax assets and liabilities be classified as noncurrent in a classified statement of financial position. The provisions of this ASU are effective for years beginning after December 15, 2016. The Company early adopted ASU 2015-17 effective December 31, 2015 on a prospective basis. Adoption of this ASU resulted in a reclassification of its net current deferred tax asset to the net non-current deferred tax asset in its consolidated balance sheet as of December 31, 2015. No prior periods were retrospectively adjusted. In January 2016, the FASB issued ASU 2016-01, "Financial Instruments—Overall: Recognition and Measurement of Financial Assets and Financial Liabilities." The main objective of this update is to enhance the reporting model for financial instruments to provide users of financial statements with more decision-useful information. The new guidance addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. This ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company is currently evaluating the new guidance to determine the impact it may have on its consolidated financial statements.

DISCONTINUED OPERATIONS	NOTE 4—DISCONTINUED OPERATIONS On August 16, 2011, the Company entered into an equity purchase agreement to sell its Quality Assurance ("QA") business to Underwriters Laboratories ("UL") for $275,000 plus assumed cash. The QA business provided consumer product testing, inspection, auditing and consulting services that enabled retailers and manufacturers to determine whether products and facilities met applicable safety, regulatory, quality, performance, social and ethical standards. In addition, the Company and UL entered into a transition services agreement, pursuant to which the Company agreed to provide certain services to UL following the closing of the sale, including accounting, tax, legal, payroll and employee benefit services. UL agreed to provide certain information technology services to the Company pursuant to such agreement. On September 1, 2011, pursuant to the terms and conditions of the equity purchase agreement, as amended, the Company transferred the applicable assets, liabilities, subsidiaries and employees of the QA business to Nutmeg Holdings, LLC ("Nutmeg") and STR International, LLC ("International", and together with Nutmeg and their respective subsidiaries, the "Nutmeg Companies"), and immediately thereafter sold its equity interest in each of the Nutmeg Companies to designated affiliates of UL for total net cash proceeds of $283,376, which included $8,376 of estimated cash assumed in certain QA locations. In accordance with ASC 250-20—Presentation of Financial Statements—Discontinued Operations and ASC 740-20—Income Taxes—Intraperiod Tax Allocation, the accompanying Consolidated Statements of Comprehensive Loss and Consolidated Cash Flows present the results of the QA business as discontinued operations. Prior to the sale, the QA business was a segment of the Company. The Company has no continuing involvement in the operations of the QA business and does not have any direct cash flows from the QA business subsequent to the sale. Accordingly, the Company has presented the QA business as discontinued operations in these consolidated financial statements. During 2015, the Company settled an income tax audit for the tax years 2009, 2010 and 2011 related to state filings of the Company's QA business sold in 2011. As a result, the Company recorded an income tax expense to discontinued operations of $21 in the current year. Additionally, the Company recorded an income tax benefit to discontinued operations of $3,967 relating to the reversal of uncertain tax positions due to the expiration of the statute of limitations and a benefit of $6 related to a statute lapse on a proposed amended return that was never filed. During 2014, the Company received proposed tax audit adjustments for the tax years 2009, 2010 and 2011 related to state filings of the Company's QA business sold in 2011. As a result, the Company recorded an aggregate income tax expense to discontinued operations of $884. The following table sets forth the operating results of the QA business presented as a discontinued operation for the years ended December 31, 2015 and 2014, respectively: Year Ended December 31, 2015 Year Ended December 31, 2014 Net sales $ — $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Loss from operations before income tax expense — — Gain on sale before income tax expense — — ​ ​ ​ ​ ​ ​ ​ ​ Net earnings before income tax expense $ — $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Income tax (benefit) expense $ ) $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​

On December 15, 2014, pursuant to the terms of the Purchase Agreement, the Company issued to Zhenfa U.S. an aggregate of 9,210,710 shares of its authorized but unissued common stock, par value $0.01 per share, for an aggregate purchase price of approximately $21,664, or $2.35 per share. The Purchased Shares represented approximately 51% of the Company's outstanding shares on the Closing Date. Due to the loss from continuing operations during the years ended December 31, 2015 and 2014, the weighted-average common shares outstanding does not include any stock options and any shares of unvested restricted common stock as these potential awards do not share in any loss generated by the Company and are anti-dilutive. Because the effect would be anti-dilutive, there were 30 and 4 shares of common stock issuable upon the exercise of options issued under the STR Holdings, Inc. 2010 Employee Stock Purchase Plan ("ESPP") that were not included in the computation of diluted weighted-average shares outstanding for the years ended December 31, 2015 and 2014, respectively. Because the effect would be anti-dilutive, there were 1,501,331 and 0 stock options outstanding that were not included in the computation of diluted weighted-average shares outstanding for the years ended December 31, 2015 and 2014, respectively.

Due to its decision to close its Malaysia facility, the Company performed an analysis to assess the specific recoverability of its property, plant and equipment using updated real estate appraisals and other data for its other fixed assets, mainly production equipment. Based upon this analysis, the Company recorded a loss on reclassification of $722 as of December 31, 2015. In October 2014, the Company sold its East Windsor, Connecticut facility for approximately $4,750. The sale of the property was part of the Company's focus to reduce its footprint and operating costs. An analysis of the asset group was performed and a loss on reclassification of $1,179 was recorded during 2014. The Company has relocated its corporate and research and development functions to its owned facility located in Enfield, Connecticut. In 2014, the Company sold its land use rights for a parcel of land located in Suzhou, Jiangsu Province, China to the Administration Committee of Changkun Industrial Government for $1,924. The Company recorded a loss on disposal of fixed assets for the sale of this asset of $435. Impairment Testing In accordance with ASC 360-Property, Plant and Equipment, the Company assesses the impairment of its long-lived assets whenever changes in events or circumstances indicate that the carrying value of such assets may not be recoverable. During each reporting period, the Company assessed if the following factors were present which would cause an impairment review: overall negative solar industry conditions; a significant or prolonged decrease in net sales generated under its trademarks; loss of a significant customer or a reduction in demand for customers' products; a significant adverse change in the extent to or manner in which the Company used its trademarks or proprietary technology; such assets becoming obsolete due to new technology or manufacturing processes entering the markets or an adverse change in legal factors; and the market capitalization of the Company's common stock. At December 31, 2015 and 2014, the Company recorded valuation allowances against its deferred tax assets and the Company determined this to be an indicator to test its long-lived assets for impairment. The valuation allowances were recorded since the Company had three consecutive years of taxable losses and it determined that its history of actual net losses was negative evidence that should be given more weight than future projections. The Company also determined the recording of valuation allowances to be an indicator to test its long-lived assets, which consist solely of property, plant and equipment, for impairment. The Company concluded that no impairment existed as the sum of the undiscounted expected future cash flows exceeded the carrying value of its asset group, which is its reporting unit, ($57,723 as of December 31, 2014) by $54,854. The key assumptions driving the undiscounted cash flows were the forecasted sales growth rate and EBITDA margin. In addition to assessing the undiscounted cash flows, the Company also assessed the specific recoverability of its property, plant and equipment using updated real estate appraisals and other data for its other fixed assets, mainly production equipment. Based upon this analysis, the Company believed its property, plant and equipment's carrying value was recoverable and depreciable lives were appropriate as of December 31, 2015 and 2014. If the Company experiences a significant reduction in future sales volume, further ASP reductions, lower profitability, ceases operations at any of its facilities, or negative changes in Malaysia, U.S. or Spain real estate markets, the Company's property, plant and equipment may be subject to future impairment or accelerated depreciation.

Subsequent to the announcement, the Company has engaged advisors and is actively trying to sell its land-use right, building and other fixed assets located at the facility. In accordance with ASC 360-Property, Plant and Equipment, the Company assessed the asset group attributed to the sale for impairment. Based upon the Company's assessment of the status of the Malaysian property, plant and equipment, all of the requirements (including the held for sale requirements) set forth in ASC 360-10-45-9 were met and the assets were reclassified on the consolidated balance sheet as of December 31, 2015 and classified as assets held for sale.

COMMITMENTS AND CONTINGENCIES	NOTE 12—COMMITMENTS AND CONTINGENCIES The Company is a party to claims and litigation in the normal course of its operations. Management believes that the ultimate outcome of these matters will not have a material adverse effect on the Company's financial position, results of operations, or cash flows. Product Performance Matters The Company provides a short-term warranty that it has manufactured its products to the Company's specifications. On limited occasions, the Company incurs costs to service its products in connection with specific product performance matters that do not meet the Company's specifications. Anticipated future costs are recorded as part of cost of sales and accrued liabilities for specific product performance matters when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated. On isolated occasions, the Company has also offered limited short-term performance warranties relating to its encapsulants not causing module power loss. The Company's encapsulants are validated by long-term performance testing during product development prior to launch and during customer certification prior to mass production. The Company has operated its solar business since the 1970s and over 20 GW of solar modules incorporating its encapsulants have been installed in the field with no reported module power performance issues caused by the Company's encapsulants and no related warranty claims to date. Based on this fact pattern, the Company has not accrued any warranty liability associated for this potential liability as its occurrence is deemed to be remote. If the Company was to ever receive a warranty claim for such matter, the Company would assess the need for a warranty accrual at that time. The Company has accrued for specific product performance matters incurred in 2015 and 2014 that are based on management's best estimate of ultimate expenditures that it may incur for such items. The following table summarizes the Company's product performance liability that is recorded in accrued liabilities in the consolidated balance sheets: December 31, 2015 December 31, 2014 Balance as of beginning of period $ $ Additions Reversals — ) Reductions ) ) Foreign exchange impact ) ) ​ ​ ​ ​ ​ ​ ​ ​ Balance as of end of period $ — $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ During 2014, the Company reversed $4,089 of an accrual related to a quality claim by one of the Company's customers in connection with a non-encapsulant product that the Company purchased from a vendor in 2005 and 2006 and resold. The reversal was recorded in other income in the consolidated statements of comprehensive loss for the year ended December 31, 2014. The Company stopped selling this product in 2006. The Company had concluded that the settlement of this contingency was no longer probable and was remote. Environmental During 2010, the Company performed a Phase II environmental site assessment at its 10 Water Street, Enfield, Connecticut location. During its investigation, the site was found to contain a presence of volatile organic compounds. The Company has been in contact with the Department of Environmental Protection and has engaged a licensed contractor to remediate this circumstance. Based on ASC 450-Contingencies, the Company has accrued the estimated cost to remediate.

COST REDUCTION ACTIONS
COST REDUCTION ACTIONS	NOTE 13—COST REDUCTION ACTIONS In light of the continued shift in module manufacturing to mainland China, and the requirement within this growing market for just-in-time delivery, the Company announced plans in 2013 to cease production at its Johor, Malaysia facility in 2014. In conjunction with the anticipated closure, the Company recognized severance and other benefits of $386 in cost of sales and $377 in selling, general and administrative expenses in 2013. During 2014, the Company reassessed the strategic benefit of its Malaysia facility. Due to continued solar trade disputes between China and the United States and Europe, including the levy of tariffs and anti-dumping duties, solar module production was expected to increase in Asia outside of China. Therefore, the Company believed its Malaysia facility was strategically located in this region, and would remain open indefinitely. As a result, the Company reversed restructuring accruals recorded in 2013 during 2014 resulting in a positive benefit to cost of sales of $407 and selling, general and administrative expense of $388. During 2014, the Company received notification that it fulfilled the necessary Spanish grant requirements provided by the government and in turn reversed $250 of an accrual initially recorded in 2012. The activity during the year ended December 31, 2014 related to cash settlements of previously accrued amounts, minor adjustments for cost reduction actions initiated in 2013 and the non-cash reversal of prior accruals relating to the Malaysia facility that would now remain open and the Spanish grants. On July 27, 2015, the Company again reassessed the continued operations of its Malaysia facility and decided to close its Malaysia facility, effective August 2, 2015 following a recent decision by the Company's largest customer to exit its OEM module production in Malaysia. The Company expects to continue to fulfill orders to this customer from its Spain and China facilities. The Company reviewed the current inventory on hand and began to transfer inventory to its other manufacturing locations. An analysis was performed and inventory was written down to net realizable value. During the second half of 2015 the Company recognized $352 of severance and benefits as well as a $467 inventory write down in cost of sales and $467 of severance and benefits in selling, general and administrative expenses related to the Malaysia facility closure. The restructuring accrual consists of $268 for severance and benefits as of December 31, 2015.

Following is a reconciliation of the Company's effective income tax rate from continuing operations to the United States federal statutory tax rate: Year Ended December 31, 2015 Year Ended December 31, 2014 Expected tax at U.S. statutory income tax rate % % U.S. state and local income taxes net of federal income tax effect % )% Foreign rate differential )% )% Foreign unremitted earnings )% )% Unrecognized tax benefits % % Stock option cancellations )% )% Change in valuation allowance )% )% Other )% % ​ ​ ​ ​ ​ ​ ​ ​ Effective tax rate % )% ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ The effect of temporary differences is included in deferred tax accounts as follows: Year Ended December 31, 2015 Year Ended December 31, 2014 Deferred tax assets: Current deferred tax assets: Accrued salaries and benefits $ — $ Deferred compensation — — Bad debt reserves — Inventories — Product performance accrual — Other — — ​ ​ ​ ​ ​ ​ ​ ​ Total current deferred tax assets before valuation allowance $ — $ ​ ​ ​ ​ ​ ​ ​ ​ Valuation allowance — ) ​ ​ ​ ​ ​ ​ ​ ​ Current deferred tax assets $ — $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Long-term deferred tax assets: Deferred compensation $ — $ Accrued compensation — Inventory — Bad debt reserves — Product performance accrual — Non-qualified stock option compensation — Restricted stock compensation — Operating loss carryforwards Fixed assets Other ​ ​ ​ ​ ​ ​ ​ ​ Total long-term deferred tax assets before valuation allowance $ $ Valuation allowance ) ) ​ ​ ​ ​ ​ ​ ​ ​ Long term-deferred tax assets — — ​ ​ ​ ​ ​ ​ ​ ​ Total deferred tax assets $ — $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Deferred tax liabilities: Foreign unremitted earnings $ — $ — ​ ​ ​ ​ ​ ​ ​ ​ Total deferred tax liabilities $ — $ — ​ ​ ​ ​ ​ ​ ​ ​ Total net deferred tax assets $ — $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ A valuation allowance is recorded on certain deferred tax assets if it has been determined it is more likely than not that all or a portion of these assets will not be realized. The Company has recorded a valuation allowance of $8,880 and $7,424 for deferred tax assets existing as of December 31, 2015 and December 31, 2014, respectively. The valuation allowance as of December 31, 2015 is attributable to deferred taxes in the United States and net operating loss carryforwards in the United States, Spain, China and Hong Kong. The valuation allowance as of December 31, 2014 is attributable to deferred taxes in the United States and net operating loss carryforwards in the United States, Spain, China and Hong Kong. During November 2015, the FASB issued ASU 2015-17, "Balance Sheet Classification of Deferred Taxes", which simplifies the presentation of deferred income taxes. This ASU requires that deferred tax assets and liabilities be classified as non-current in a statement of financial position. The Company early adopted ASU 2015-17 effective December 31, 2015 on a prospective basis. Adoption of this ASU resulted in a reclassification of the Company's net current deferred tax asset to the net non-current deferred tax asset in its consolidated balance sheet as of December 31, 2015. No prior periods were retrospectively adjusted. The Company recognizes interest accrued related to its liability for unrecognized tax benefits and penalties in income tax expense. The Company recorded interest and penalties related to unrecognized tax benefits as a component of income tax expense from continuing operations in the amount of approximately $(39) and $(85) for the years ended December 31, 2015 and 2014, respectively. The Company had approximately $0 and $1,183 for the payments of interest and penalties accrued at December 31, 2015 and December 31, 2014, respectively. A reconciliation of the beginning and ending amount of the Company's liability for unrecognized tax benefits, excluding interest and penalties, is as follows (includes continuing and discontinued operations): Balance at January 1, 2014 $ ​ ​ ​ ​ ​ Additions for tax positions of prior years — Reductions for tax positions of prior years ) ​ ​ ​ ​ ​ Balance at December 31, 2014 $ ​ ​ ​ ​ ​ Additions for tax positions of prior years — Reductions for tax positions of prior years ) ​ ​ ​ ​ ​ Balance at December 31, 2015 $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ The amount of unrecognized tax benefit that would potentially impact the Company's effective tax rate from continuing operations and discontinued operations was $0 and $3,199 (excluding interest and penalties) as of December 31, 2015 and 2014, respectively. During 2015, the Company had reductions for tax positions of prior years of $3,199 for a lapse in the statute of limitations. The Company recorded an income tax benefit in continuing operations of $375 (excluding interest and penalties) and an income tax benefit in discontinued operations of $2,824 (excluding interest and penalties). The Company has open tax years from 2004-2015 with various foreign tax jurisdictions. The Company expects $0 (excluding interest and penalties) of unrecognized tax benefits to reverse within the next twelve months. The Company conducts its business globally and as a result, the Company and one or more of its subsidiaries file income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. The Company is subject to examination by taxing authorities in each of these jurisdictions. The Company has an open tax year of 2015 for U.S. federal tax purposes. The Company has open tax years from 2012-2015 with various state tax jurisdictions. In connection with the examination of the Company's tax returns, contingencies can arise that generally result from differing interpretations of applicable tax laws and regulations as they relate to the amount, timing or inclusion of revenues or expenses in taxable income, or the sustainability of tax credits to reduce incomes taxes payable. The Company believes it has sufficient accruals for its contingent tax liabilities. Annual tax provisions include amounts considered sufficient to pay assessments that may result from examination of prior year tax returns, although actual results may differ. During 2014, and 2015, the Company went through several examinations that resulted in no material adjustments, including: an examination in the United States by the Internal Revenue Service for tax years 2011, 2012, 2013, and 2014; an examination by the State of Florida for the tax years 2010, 2011 and 2012; and an inspection for the 2012 return filed for Spain. As of December 31, 2015 the Company had an income tax receivable of $8,252 relating to the 2014 federal net operating loss carryback, for which the Company was awaiting final approval from the U.S. Congressional Joint Committee on Taxation. During 2015, the Company settled an audit conducted by the State of Massachusetts for tax years 2009, 2010, and 2011, relating to the Company's QA business, which was sold in 2011. The Company recorded an income tax expense to discontinued operations of $21 and $884 for the years ended December 31, 2015 and 2014, respectively. Refer to Note 4-Discontinued Operations for further explanation. No U.S. taxes need to be provided for the undistributed earnings of a foreign subsidiary if the Company can assert that such earnings are planned to be reinvested indefinitely outside of the United States. The Company periodically assesses its business operations and the cash flow needs of its foreign and domestic subsidiaries to determine if the earnings of any of its foreign subsidiaries will be indefinitely reinvested outside the United States. The Company is not permanently reinvesting earnings generated in any foreign jurisdiction. The Company's subsidiary in Malaysia is operating under a tax holiday arrangement that extends through 2019. The impact of the tax holiday on its effective rate is a reduction in the benefit of 11.7% and 5.6% percentage points for 2015 and 2014, respectively.

STOCK-BASED COMPENSATION
STOCK-BASED COMPENSATION	NOTE 18—STOCK-BASED COMPENSATION On November 6, 2009, the Company's Board of Directors approved the Company's 2009 Equity Incentive Plan (the "2009 Plan") which became effective on the same day. Effective May 14, 2013, the 2009 Plan was amended to increase the number of shares subject to the Plan. As a result, a total of 4,133,133 shares of common stock are reserved for issuance under the 2009 Plan. The 2009 Plan is administered by the Board of Directors or any committee designated by the Board of Directors, which has the authority to designate participants and determine the number and type of awards to be granted, the time at which awards are exercisable, the method of payment and any other terms or conditions of the awards. The 2009 Plan provides for the grant of stock options, including incentive stock options and nonqualified stock options, collectively, "options," stock appreciation rights, shares of restricted stock, or "restricted stock," rights to dividend equivalents and other stock-based awards, collectively, the "awards." The Board of Directors or the committee will, with regard to each award, determine the terms and conditions of the award, including the number of shares subject to the award, the vesting terms of the award, and the purchase price for the award. Awards may be made in assumption of or in substitution for outstanding awards previously granted by the Company or its affiliates, or a company acquired by the Company or with which it combines. Options outstanding generally vest over a three or four-year period and expire ten years from date of grant. The following table summarizes the Company's stock-based compensation awards under the 2009 Plan during 2015 and 2014: Date Award Type Exercise Price Shares Recipient 2 nd Quarter 2015 Restricted Stock $ Board of Directors 2 nd Quarter 2015 Restricted Stock $ Board of Directors 1 st Quarter 2015 Options $ Various Employees 1 st Quarter 2015 Restricted Stock $ Board of Directors 4 th Quarter 2014 Restricted Stock $ Board of Directors 3 rd Quarter 2014 Restricted Stock $ Board of Directors 2 nd Quarter 2014 Restricted Stock $ Board of Directors 2 nd Quarter 2014 Options $ Various Employees 1 st Quarter 2014 Restricted Stock $ Board of Directors There were 1,828,786 shares available for grant under the 2009 Plan as of December 31, 2015. The 1,964,665 options granted during the year ended December 31, 2015, vest equally on each of the three anniversaries of the date of grant, subject to acceleration in certain circumstances. The Company determined the fair value of the stock options issued in 2015 and 2014 using the Black-Scholes option pricing model. The Company's assumptions about stock-price volatility were based on the historical implied volatilities of its common stock and those of other publicly traded options to buy stock with contractual terms closest to the expected life of options granted to the Company's employees. The expected term represents the estimated time until employee exercise is estimated to occur taking into account vesting schedules and using the Hull-White model. The risk-free interest rate for periods within the contractual life of the award is based on the U.S. Treasury 10 year zero-coupon strip yield in effect at the time of grant. The expected dividend yield was based on the assumption that no dividends are expected to be distributed in the near future. The following table presents the assumptions used to estimate the fair values of the stock options granted during the periods presented below: Year Ended December 31, 2015 Year Ended December 31, 2014 Expected volatility % % Risk-free interest rates % % Expected term (in years) Forfeiture rate % — % Dividend yield — — Weighted-average estimated fair value of options granted during the period $ $ Stock Option Cancellation s During 2014, 1,365,916 stock options were cancelled due to the termination of employment of certain employees at the end of 2013. Since no tax windfall pool existed in additional paid-in-capital, the reduction in the deferred tax asset of $1,377 was charged to income tax expense as a discrete item in 2014. Due to the closing of the Transaction with Zhenfa, which constituted a change of control transaction under the Company's equity incentive plan, the Board of Directors, as permitted under such plan, to cancel all outstanding options effective as of the closing of that transaction. The Company cancelled the options due to material changes in its business and capital structure that would significantly impact its previously issued options. These changes included the share issuance which represented a change in control and approximately doubled the Company's share count, payment of the Special Dividend and the reverse stock split. All of these items represented material changes to its capital structure and market capitalization and could materially impact the trading price of its common stock. Due to the uncertainty, the Company cancelled the options prior to the transaction with Zhenfa and issued new options at a later date after the capital structure was established following the completion of the reverse stock split, and the Company's stock price traded for a period of time subsequent to all of these transactions. In total, options to purchase 3,405,389 shares were cancelled, of which options to purchase 2,100,389 shares had been fully vested. The Company recorded a non-cash stock compensation expense of $1,076 associated with the cancellation which is reflected in selling, general and administrative expenses in the Company's consolidated statements of comprehensive loss. The following table summarizes the stock option activity under the Company's 2009 Plan for the two years ended December 31, 2015: Options Outstanding Number of Shares Weighted- Average Exercise Price Weighted- Average Remaining Contractual Term (in years) Weighted- Average Grant-Date Fair Value Aggregate Intrinsic Value(1) Balance at January 1, 2014 $ $ $ ) Options granted $ — $ $ — Exercised — $ — — $ — $ — Cancelled/forfeited ) $ — $ $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Balance at December 31, 2014 — $ — — $ — $ — Options granted $ — $ $ ) Exercised — $ — — $ — $ — Cancelled/forfeited ) $ — $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Balance at December 31, 2015 $ $ $ ) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Vested and exercisable as of December 31, 2015 — $ — — $ — $ — Vested and exercisable as of December 31, 2015 and expected to vest thereafter $ $ $ ) (1) The aggregate intrinsic value for December 31, 2015 is calculated as the difference between the exercise price of the underlying awards and the closing stock price of $0.37 of the Company's common stock on December 31, 2015. The aggregate intrinsic value for January 1, 2014 is calculated using the closing stock price of $1.37 on December 31, 2014. As of December 31, 2015, there was $1,032 of unrecognized compensation cost related to outstanding stock option awards. This amount is expected to be recognized over a weighted-average remaining vesting period of less than one year. To the extent the actual forfeiture rate is different from what the Company has anticipated, stock-based compensation related to these awards will be different from its expectations. The Company did not receive any proceeds related to the exercise of stock options for the years ended December 31, 2015 and 2014.

This amount is expected to be recognized over a weighted-average remaining vesting period of less than one year. To the extent the actual forfeiture rate is different from what the Company has anticipated, stock-based compensation related to these awards will be different from its expectations. On November 9, 2010, the Company's Board of Directors adopted the Employee Stock Purchase Plan and reserved 166,667 shares of the Company's common stock for issuance thereunder. The ESPP was made effective upon its approval by the votes of the Company's stockholders on May 24, 2011 during the Company's annual meeting for the purpose of qualifying such shares for special tax treatment under Section 423 of the Internal Revenue Code of 1986, as amended. As of October 1, 2015 the Company terminated the ESPP. Under the ESPP, eligible employees used payroll withholdings to purchase shares of the Company's common stock at a 10% discount. The Company had established four offering periods in which eligible employees could participate. The first offering period commenced in the fourth quarter of 2011. The Company purchased the number of required shares each period based upon the employees' contribution plus the 10% discount. The number of shares purchased times the 10% discount was recorded by the Company as stock-based compensation. The Company recorded less than $1 in stock-based compensation expense relating to the ESPP for the years ended December 31, 2015 and 2014. Stock-based compensation expense was included in the following consolidated statements of comprehensive loss categories for continuing operations: Years Ended December 31, 2015 2014 Selling, general and administrative expense $ $ Research and development expense $ — $ — ​ ​ ​ ​ ​ ​ ​ ​ Total stock-based compensation expense $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Deferred Compensation The Company had a deferred compensation arrangement with certain members of management, including Robert S. Yorgensen, that stated upon the earlier of December 31, 2015, sale of the Company (which included a change of control transaction), or termination of employment for any reason, the members were entitled to bonus payments based upon a formula set forth in their respective employment agreements. The payments were tied to distribution amounts they would have received with respect to their former ownership in the predecessor Company if the assets were sold at fair market value compared to the value of the Company's stock price. The amount of the potential bonus payment was capped at $1,180. In accordance with ASC 718-30, the obligation should have been re-measured quarterly at fair value. The Company determined fair value using observable current market information as of the reporting date. The most significant input to determine the fair value was determined to be the Company's common stock price which is a Level 2 input. Based upon the difference of the floor in the agreements and the effective valuation of the Transaction of $4.80 per share for Mr. Yorgensen, $204 of accrued compensation was paid out during the first quarter of 2015. As of December 31, 2015, no deferred compensation arrangements exist.

REPORTABLE SEGMENT AND GEOGRAPHICAL INFORMATION
REPORTABLE SEGMENT AND GEOGRAPHICAL INFORMATION	NOTE 19—REPORTABLE SEGMENT AND GEOGRAPHICAL INFORMATION ASC 280-10-50-Disclosure about Segments of an Enterprise and Related Information, establishes standards for the manner in which companies report information about operating segments, products, geographic areas and major customers. The method of determining what information to report is based on the way that management organizes the operating segments within the enterprise for making operating decisions and assessing financial performance. Prior to the sale of its QA business, the Company reported two operating segments: QA and Solar. Due to the sale, QA is being reported as a discontinued operation and the Company reassessed its segment reporting. Since the Company has one product, sells to global customers in one industry, procures raw materials from similar vendors and expects similar long-term economic characteristics, the Company has one reporting segment and the information as to its operation is set forth below. Adjusted EBITDA is the main metric used by the management team and the Board of Directors to plan, forecast and review the Company's segment performance. Adjusted EBITDA represents net loss from continuing operations before interest income and expense, income tax expense, depreciation, amortization of intangible assets, stock-based compensation expense, restructuring, transaction fees and certain non-recurring income and expenses from the results of operations. The following tables set forth information about the Company's operations by its reportable segment and by geographic area: Operations by Reportable Segment Year Ended December 31, 2015 Year Ended December 31, 2014 Reconciliation of Adjusted EBITDA to Net Loss from Continuing Operations Adjusted EBITDA $ ) $ ) Depreciation and amortization ) ) Interest (expense) income, net ) Income tax benefit (expense) ) Other non-operating expenses ) — Restructuring ) Stock-based compensation ) ) Non-cash reversal of loss contingency — Loss on reclassification of held for sale assets ) ) Non-cash reversal of Spanish grants — (Loss) gain on disposal of property, plant and equipment — ) ​ ​ ​ ​ ​ ​ ​ ​ Net Loss from Continuing Operations $ ) $ ) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Operations by Geographic Area Year Ended December 31, 2015 Year Ended December 31, 2014 Net Sales United States $ $ Spain China Malaysia ​ ​ ​ ​ ​ ​ ​ ​ Total Net Sales $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Long-Lived Assets by Geographic Area December 31, 2015 December 31, 2014 Long-Lived Assets United States $ $ Spain China Malaysia — Hong Kong — ​ ​ ​ ​ ​ ​ ​ ​ Total Long-Lived Assets $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Foreign sales are based on the country in which the net sales originated.

("STR China") entered into a supply agreement (the "Huhui Supply Agreement") dated as of December 31, 2014 with Zhangjiagang Huhui Segpv Co. Ltd ("Huhui"), a solar module manufacturer and an affiliate of Zhenfa. Pursuant to the Huhui Supply Agreement, STR China agreed to supply Huhui with the Company's encapsulant products and Huhui agreed (i) to purchase not less than 535 MW worth of encapsulants (the "Minimum Amount") during each contract year, (ii) to pay the Company a deposit equal to 10% of the Minimum Amount, and (iii) not to purchase encapsulant products from other encapsulant manufacturers. The term of the Huhui Supply Agreement is for one year; provided, however, that the initial contract may be extended for an additional six months in the event that Huhui has not purchased the Minimum Amount at the end of the first year anniversary of the effective date of the Huhui Supply Agreement. The Huhui Supply Agreement further provides that Huhui's obligations are contingent (unless otherwise provided in the agreement) upon (i) the delivery by STR China of an initial shipment of products in accordance with the specifications and (ii) the qualification of the products by Huhui during a sample production run of not less than 30 days. As of December 31, 2015, Huhui had not commenced the sample production run. The Huhui Supply Agreement shall automatically renew for additional one year terms if either party fails to notify the other party at least 90 days prior to the end of the then current term that it is electing to terminate the agreement. The Company believes that the terms and conditions set forth in the Huhui Agreement are fair and reasonable to the Company. The Company received $1,148 as a client deposit from Huhui during the year ended December 31, 2015, which is included in accrued liabilities on the Consolidated Balance Sheets. During the year ended December 31, 2015 the Company recorded $94 in net sales to this customer. Module-for-Encapsulant Swap Transaction During the second quarter of 2015, the Company entered into a module-for-encapsulant swap transaction with Zhenfa and Zhejiang ReneSola Jiangsu Co., Ltd. ("ReneSola") to settle outstanding accounts receivable due from ReneSola. As part of this three-party transaction, the Company agreed to accept solar modules as settlement of approximately $7,487 of outstanding receivables from ReneSola, and Zhenfa agreed to purchase these modules from the Company for $7,487. As of December 31, 2015 the Company received $5,429 (excluding foreign exchange impact) leaving a receivable of $2,058 due from Zhenfa related to this transaction. Employment of Zhenfa Personnel On July 27, 2015, the Company announced the appointment of Mr. Qu Chao to the office of Vice President, Strategic Investment, and Mr. Kong Weijie as Vice President, Business Development and General Manager, China, effective August 1, 2015. At the time, Messrs. Qu and Kong were officers of Zhenfa. Mr. Qu was also a member of the Company's Board of Directors. The services of Messrs. Qu and Kong were provided by Zhenfa, at no charge to the Company, pursuant to the terms of the Zhenfa Sales Service Agreement, as described in Note 3 above. In October 2015, the Company was advised by representatives of Zhenfa that Mr. Qu resigned as an officer of Zhenfa and that Zhenfa would no longer be supporting Mr. Qu's services as Vice President, Strategic Investment. The Company has not separately engaged Mr. Qu to continue to provide those services as he is no longer an officer of the Company. As of the date of this report, Mr. Qu is no longer a director of the Company. Mr. Kong currently attempts to divide his time evenly between his duties with Zhenfa and STR. As a result, the value of Mr. Kong's services provided must be reflected in the Company's consolidated financial statements. This shared services arrangement was recorded as a non-cash expense in selling, general and administrative expenses of $93 for the year ended December 31, 2015.

ASC 820-10 classifies the inputs used to measure fair value into the following hierarchy: Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities Level 2: Unadjusted quoted prices in active markets for similar assets or liabilities, or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability Level 3: Unobservable inputs for the asset or liability The carrying values for cash, accounts receivable, income tax receivable, accounts payable, accrued liabilities, income taxes payable and other current assets and liabilities approximate their fair values due to their short maturities. The carrying value of the Company's money market funds is based on the balance of its money market funds as of December 31, 2015, which is a Level 1 input. The carrying value of deferred compensation in 2014, which is a Level 2 input, was based upon the effective valuation of the transaction with Zhenfa of $4.80 per share. See Note 14.
Foreign Currency Translation and Transactions	Foreign Currency Translation and Transactions. The Company's international operations use the local currency as their functional currency, except for its Malaysian subsidiary whose functional currency is the U.S. dollar. Assets and liabilities of international operations are translated at period-end rates of exchange; revenues and expenses are translated at average rates of exchange. The resulting translation gains or losses are reflected in accumulated other comprehensive loss. Gains or losses resulting from foreign currency transactions are included in net loss.
Cash and Cash Equivalents	Cash and Cash Equivalents. All highly-liquid investments with a maturity of three months or less at the date of purchase are considered to be cash equivalents. The Company deposits its cash balances with a limited number of banks. Cash balances in these accounts generally exceed government insured limits.
Recognition of Revenue and Accounts Receivable	Recognition of Revenue and Accounts Receivable. The Company recognizes revenue net of any sales returns and allowances when evidence of an arrangement exists, delivery of the product or service has occurred and title and risk of loss have passed to the customer, the sales price is fixed or determinable, and collectability of the resulting receivable is reasonably assured. The Company recognizes revenue from the manufacture and sale of its encapsulants, which is the only contractual deliverable, either at the time of shipping or at the time the product is received at the customer's port or dock, depending upon terms of the sale. The Company does not offer a general right of return on its products. On isolated occasions, the Company has offered limited short-term performance warranties relating to its encapsulants not causing module power loss. The Company's encapsulants are validated by long-term performance testing during product development prior to launch and during customer certification prior to mass production. The Company has operated its solar business since the 1970s and over 20 GW of solar modules incorporating its encapsulants have been installed in the field with no reported module power performance issues caused by its encapsulants and no related warranty claims to-date. Based on this fact pattern, the Company has not accrued any warranty liability associated for this potential liability as its occurrence is deemed to be remote. If the Company were to ever receive a warranty claim for such matter, it would assess the need for a warranty accrual at that time.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts. The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. The Company reviews the collectability of its receivables on an ongoing basis and writes off accounts receivable after reasonable collection efforts have been made and collection is deemed uncollectible.
Inventories	Inventories. The Company's inventories are stated at the lower of cost or market. The Company's primary raw materials consist of resin, paper, packaging material and chemicals/additives. The Company's finished goods inventories are typically made-to-order and possess a shelf life of six to nine months from the date of manufacture. Cost is determined on a first-in, first-out basis and includes both the costs of acquisition and the costs of manufacturing. These costs include direct material, direct labor and fixed and variable indirect manufacturing costs, including depreciation expense. The Company will write down inventory to its net realizable value when it is probable that the inventory carrying cost is not fully recoverable through sale or other disposition. The Company's write-down considers overall market conditions, customer inventory levels, legal or contractual provisions and age of the inventories. In 2015, the Company reserved $696 of inventory, a majority of which was related to excess raw material and expired finished goods inventory. In 2014, the Company reserved $1,025 of inventory, a majority of which was related to excess raw material and expired finished goods inventory related to recent product introductions.
Long-Lived Assets, property, plant and equipment	Long-Lived Assets. The Company's long-lived assets consist of property, plant and equipment. Property, plant and equipment are recorded at cost and include expenditures for items that increase the useful lives of existing equipment. Maintenance and repairs are expensed as incurred. Property, plant and equipment accounts are relieved at cost, less related accumulated depreciation, when properties are disposed of or otherwise retired. Gains and losses from disposal of property, plant and equipment are included in net loss. In accordance with ASC 360—Property, Plant, and Equipment, the Company reviews the carrying value of its long-lived assets, including property, plant and equipment, for impairment when events or changes in circumstances indicate the carrying value of an asset may not be recoverable. If a long-lived asset is found to be impaired, the amount recognized for impairment is equal to the difference between the carrying value and the asset's fair value. Fair value is estimated based upon discounted future cash flows, appraisals or other reasonable estimates of fair market value.
Asset Retirement Obligations	Asset Retirement Obligations. The Company accounts for asset retirement obligations in accordance with ASC 410—Asset Retirement and Environmental Obligations, which requires a company to recognize a liability for the fair value of obligations to retire tangible long-lived assets when there is a contractual obligation to incur such costs. The Company has recorded its asset retirement obligations relating to the cost of removing improvements from lease facilities at the end of the lease terms. The Company's conditional asset retirement obligations are not material.
Leases	Leases. The Company leases certain facilities and equipment used in its operations. The Company accounts for its leases under the provisions of ASC 840—Leases, which requires that leases be evaluated and classified as operating or capital leases for financial reporting purposes. Operating lease expense is recorded on a straight-line basis over the lease term.
Income Taxes	Income Taxes. The Company accounts for income taxes using the asset and liability method in accordance with ASC 740—Income Taxes. Under this method, the Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and for operating loss and tax credit carryforwards. The Company estimates its deferred tax assets and liabilities using the enacted tax laws expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled, and will recognize the effect of a change in tax laws on deferred tax assets and liabilities in the results of its operations during the period that includes the enactment date. The Company records a valuation allowance to reduce its deferred tax assets if it determines that it is more likely than not that some or all of the deferred tax assets will not be realized. The Company operates in multiple taxing jurisdictions and is subject to the jurisdiction of a number of U.S. and non-U.S. tax authorities and to tax agreements and treaties among those authorities. Operations in these jurisdictions are taxed on various bases in accordance with jurisdictional regulations. Tax benefits related to uncertain tax positions taken or expected to be taken on a tax return are recorded when such benefits meet a more likely than not threshold. Otherwise, these tax benefits are recorded when a tax position has been effectively settled, which means that the appropriate taxing authority has completed their examination even though the statute of limitations remains open or the statute of limitation expires. Interest and penalties related to uncertain tax positions are recognized as part of the Company's provision for income taxes and are accrued beginning in the period that such interest and penalties would be applicable under relevant tax law until such time that the related tax benefits are recognized. See Note 16.
Factoring Arrangement	Factoring Arrangement. The Company has entered into a factoring agreement to sell, with recourse, certain European, U.S. and other foreign company-based receivables to Eurofactor Hispania S.A.U. The Company receives funds from the factor for certain outstanding receivables for which the Company records a liability. Once the customer pays the factor directly for those receivables the Company clears the accounts receivable and the liability. As of December 31, 2015 the Company has recorded $483 as due to factoring on the consolidated balance sheets. See Note 15.
Product Performance Accrual	Product Performance Accrual. The Company provides a short-term warranty that it has manufactured its products to the Company's specifications. On limited occasions, the Company incurs costs to service its products in connection with specific product performance matters that do not meet the Company's specifications. Anticipated future costs are recorded as part of cost of sales and accrued liabilities for specific product performance matters when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated. On isolated occasions, the Company has offered limited short-term performance warranties relating to its encapsulants not causing module power loss. The Company's encapsulants are validated by long-term performance testing during product development prior to launch and during customer certification prior to mass production. The Company has operated its solar business since the 1970s and over 20 GW of solar modules incorporating its encapsulants have been installed in the field with no reported module power performance issues caused by its encapsulants and no related warranty claims to date. Based on this fact pattern, the Company has not accrued any warranty liability associated for this potential liability as its occurrence is deemed to be remote. If the Company were to ever receive a warranty claim for such matter, it would assess the need for a warranty accrual at that time.
Cost of Sales	Cost of Sales. The Company includes the cost of inventory sold and related costs for the distribution of its product in cost of sales. These costs include raw materials and other components, direct labor, product performance matters, manufacturing overhead, salaries, and other personnel-related expenses, write-off of inventory, quality control, freight, insurance and depreciation. Shipping and handling costs are classified as a component of cost of sales. Customer payments for shipping and handling costs are recorded as a component of net sales.
Selling, General and Administrative Expenses	Selling, General and Administrative Expenses. Selling, general and administrative expenses consist primarily of salaries, travel, commissions and other personnel-related expenses for employees engaged in sales, marketing and support of the Company's products and services, trade shows and promotions. General and administrative expenses consist of expenses for the Company's finance, administrative, information technology, compliance and human resource functions.
Research and Development Expense	Research and Development Expense. The Company's research and development expense consists primarily of salaries and fringe benefit costs and the cost of materials and outside services used in its pre-commercialization process and development efforts. The Company records depreciation expense for equipment that is used specifically for research and development activities.
Stock-Based Compensation	Stock-Based Compensation. In accordance with ASC 718—Compensation-Stock Compensation, the Company recognizes the grant date fair value of stock-based awards granted to employees as compensation expense over the vesting period of the awards. See Note 18.
Loss Per Share	Loss Per Share. The Company computes basic loss per common share in accordance with ASC 260—Earnings Per Share. Under the provisions of ASC 260, basic net loss per common share is computed by dividing the net loss available to common stockholders by the weighted-average common shares outstanding during the period. Diluted net loss per common share adjusts basic net loss per common share for the effects of stock options and restricted stock awards only in periods in which such effect is dilutive. See Note 5.
Comprehensive Loss	Comprehensive Loss. Comprehensive loss consists of net loss and the effects on the consolidated financial statements of translating the financial statements of the Company's international subsidiaries. Comprehensive loss is presented in the consolidated statements of comprehensive loss. The Company's accumulated other comprehensive loss is presented as a component of equity in its consolidated balance sheets and consists of the cumulative amount of the Company's foreign currency translation adjustments, net of tax.
Recent Accounting Pronouncements	Recent Accounting Pronouncements: In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, "Revenue from Contracts with Customers" (Topic 606). This ASU is intended to clarify the principles for recognizing revenue by removing inconsistencies and weaknesses in revenue requirements; providing a more robust framework for addressing revenue issues; improving comparability of revenue recognition practices across entities, industries, jurisdictions and capital markets; and providing more useful information to users of financial statements through improved revenue disclosure requirements. The provisions of this ASU are effective for interim and annual periods beginning after December 15, 2016. On August 12, 2015, the FASB issued ASU 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date," which delays the effective date of ASU 2014-09 by one year. The new standard is effective for reporting periods beginning after December 15, 2017. Early application is permitted for reporting periods beginning after December 15, 2016. The Company is currently evaluating the new guidance to determine the impact it may have to its consolidated financial statements. In February 2015, the FASB issued ASU No. 2015-02, "Consolidation (Topic 810) Amendments to the Consolidation Analysis." The amendments contained in this update affect reporting entities that are required to evaluate whether they should consolidate certain legal entities. All legal entities are subject to reevaluation under the revised consolidation model. The amendments in this update affect limited partnerships and similar legal entities, evaluating fees paid to a decision maker or a service provider as a variable interest, the effect of fee arrangements on the primary beneficiary determination, the effect of related parties on the primary beneficiary determination and certain investment funds. This ASU is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. The Company is currently evaluating the new guidance to determine the impact it may have to its consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, "Simplifying the Measurement of Inventory." This ASU changes the measurement principle for inventory from the lower of cost or market to lower of cost and net realizable value. Net realizable value is defined as the estimated selling prices in the ordinary course of business; less reasonably predictable costs of completion, disposal and transportation. The provisions of this ASU are effective for years beginning after December 15, 2016. The Company is currently evaluating the new guidance to determine the impact it may have to its consolidated financial statements. In November 2015, the FASB issued ASU 2015-17, "Balance Sheet Classification of Deferred Taxes." This ASU simplifies the presentation of deferred income taxes. The amendments in this update require that deferred tax assets and liabilities be classified as noncurrent in a classified statement of financial position. The provisions of this ASU are effective for years beginning after December 15, 2016. The Company early adopted ASU 2015-17 effective December 31, 2015 on a prospective basis. Adoption of this ASU resulted in a reclassification of its net current deferred tax asset to the net non-current deferred tax asset in its consolidated balance sheet as of December 31, 2015. No prior periods were retrospectively adjusted. In January 2016, the FASB issued ASU 2016-01, "Financial Instruments—Overall: Recognition and Measurement of Financial Assets and Financial Liabilities." The main objective of this update is to enhance the reporting model for financial instruments to provide users of financial statements with more decision-useful information. The new guidance addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. This ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company is currently evaluating the new guidance to determine the impact it may have on its consolidated financial statements.
