Accounting Policies [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [Text Block]	(2) Summary of Significant Accounting Policies and Significant Concentrations and Risks (a) Basis of Presentation The accompanying consolidated financial statements of the Company have been prepared and presented in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The realization of assets and the satisfaction of liabilities in the normal course of business are dependent on, among other things, the Company’s ability to operate profitably and to generate cash flows from operations, and the ability to pursue financing arrangements, including the renewal or rollover of its bank borrowings, to support its working capital requirements and its obligations and commitments on loans and borrowings when they become due. The following factors raise substantial doubt about the Company’s ability to continue as a going concern: ⋅ For the year ended December 31, 2016, the Company incurred a net loss of RMB 2,118,969 305,195 ⋅ As of December 31, 2016, the Company had a total deficit attributable to the Company of RMB 15,428,426 2,222,156 7,471,576 1,076,131 ⋅ As of December 31, 2016, the Company had cash, cash equivalents and restricted cash of RMB 868,439 125,081 9,010,205 1,297,739 2,523,621 363,477 ⋅ As of December 31, 2016 and from the date of issuance of these statements, Baoding Tianwei Yingli New Energy Resources Co., Ltd. (“Tianwei Yingli”), one of the Company’s major manufacturing subsidiaries, had RMB 1,943,707 279,952 1,993,518 287,126 ⋅ As of December 31, 2016 and from the date of issuance of these statements, the Company had RMB 222,331 32,022 190,967 27,505 ⋅ As of December 31, 2016, except for those loans and debts mentioned above, total short term loans expected to be repaid within one year is RMB 7,080,959 1,019,870 The liquidity of the Company is primarily dependent on its ability to generate adequate cash flows from operations, to renew or rollover its short-term borrowings and to obtain adequate external financings to support its working capital and meet its obligations and commitments when they become due. The Company has carried out a review of its cash flow forecast for the twelve months from the date of issuance of these statements. In preparing the cash flow forecast, the Company's management has considered historical cash requirements of the Company, the Company's expected debt repayment obligations in 2017 and beyond, the Company’s plan to further reduce operating costs and expenses, the Company's plan to receive cash from disposal of certain equity investments, as well as the alternative financing plans discussed in detail below. The Company's management also made the assumption about the numbers of shipments of modules and gross profit margin. The Company is currently exploring a variety of alternative financing plans to improve the Company’s liquidity and financial position as follows: Form a Special Committee and Introducing Strategic Investors The Company issued a press release on March 7, 2017 and stated that, in order to properly consider the Company's options with respect to and ultimately resolve the debt repayment issues faced by the Company's principal subsidiaries, the Company's board of directors has formed a special committee (the "Special Committee") comprised solely of independent directors to assess the Company's operating and financial situation and evaluate, develop and recommend one or more strategic alternatives and financing plans potentially workable to the Company in order to improve its debt structure. The Company is also in negotiation proactively with certain investors for potential strategic investments in the Company or its major subsidiaries. Such financing plan and strategic investments, if successfully completed, will further increase the liquidity of the Company and improve its debt-to-equity ratio. Debt Restructuring On May 3, 2017, the Company has paid the RMB 300 1,757,000 Out of the total RMB 1,757,000, medium-term notes of RMB 357,000 October 13, 2015 1,400,000 May 12, 2016 Also, as part of the Company’s plan to improve liquidity, for year ended December 31, 2016, the Company successfully negotiated with certain suppliers, and these suppliers agreed to waive partial amount of the long ageing accounts payables. Total amount waived by the suppliers in 2016 as a result of the settlement was RMB 22,165 (US$ 3,192) Renewal or Rollover of Borrowings and other Financing Arrangements The Company has maintained good relationships with its lending banks and other financial institutions in China. While there can be no assurance that the Company will be able to refinance its short-term borrowings as they become due, historically, the Company has renewed or rolled over most of its short-term bank and other borrowings upon their maturity dates and has assumed it will continue to be able to do so. As of March 31, 2017, the Company has successfully renewed or rolled over RMB 255.7 36.8 In addition, the Company has obtained financing through other arrangements, such as failed sale and lease back of certain machinery and equipment and financing in the form of sale and repurchase of certain equity interest in its subsidiary, in substance, they are financing in nature and recorded as liabilities. Based on the management’s assessment, there can be no assurance, however, that such expected financing plans will be successfully completed on terms acceptable to the Company, or effectively implemented within one year after the date that the consolidated financial statements are issued, or when implemented, it will mitigate the relevant conditions or events that raise substantial doubt about the Company's ability to continue as a going concern. The Company’s financing plans for its continuing operations, even if successful, may not result in sufficient cash flow to finance and maintain its business. Facts and circumstances including recurring losses, negative working capital, net cash outflows, and uncertainties on the repayment of the debts raise substantial doubt about the Company’s ability to continue as a going concern. The financial statements do not include any adjustments that might result from the outcome of this uncertainty. (b) Principles of Consolidation The accompanying consolidated financial statements include the accounts of Yingli Green Energy and its subsidiaries. For consolidated subsidiaries where the Company’s ownership in the subsidiary is less than 100 The Company applies the guidance codified in Accounting Standard Codification 810, Consolidations (“ASC 810”) on accounting for VIEs and their respective subsidiaries, which requires certain variable interest entities to be consolidated by the primary beneficiary of the entity in which it has a controlling financial interest. A VIE is an entity with one or more of the following characteristics: (a) the total equity investment at risk is not sufficient to permit the entity to finance its activities without additional financial support; (b) as a group, the holders of the equity investment at risk lack the ability to make certain decisions, the obligation to absorb expected losses or the right to receive expected residual returns, or (c) an equity investor has voting rights that are disproportionate to its economic interest and substantially all of the entity’s activities are on behalf of the investor. Accordingly, the financial statements of the VIEs and VIEs’ subsidiaries are consolidated into the Company’s financial statements. In 2014, the Company signed several contracts with Yingli PV Investment Group Co., Ltd. (“Yingli PV Group”) to construct all project assets on behalf of the Company. Each project asset is owned by a special purpose entity which is owned 100% by Yingli PV Group. According to the aforementioned contracts, 1) The Company could claim the ownership of these PV projects at any time during the PV project construction progress by demanding Yingli PV Group to transfer its 100 In 2014, the Company entered into two separate agreements with a related party to dispose the Company’s 100% equity interest in two subsidiaries. The disposal gain of RMB 23,943 146,606 122,663 182,286 59,623 In September 2015, the Company entered into an agreement with Yingli PV Group to terminate the above-mentioned construction contracts and the Company was no longer entitled to any rights or undertook any obligations under the aforementioned contracts. As a result, the Company disposed all the project assets under the VIE structure to Yingli PV Group. Total consideration for disposal of all entities under the VIE structure was RMB 554,452 6,852 561,304 1,886,045 1,324,741 In 2015, the Company entered into three separate agreements with three entities unrelated to the Company to dispose the Company’s 100 28,430 4,389 30,002 4,631 1,572 243 180,752 179,180 In 2016, the Company entered into four separate agreements with two entities unrelated to the Company, and two related parties to dispose the Company’s 100 34,339 4,946 5,026 724 29,332 29,313 4,222 53,411 82,724 (c) Significant Concentrations and Risks Revenue concentrations The Company’s business depends substantially on government incentives given to its customers. In many countries in which the Company sells its products, the market of the Company’s products would not be commercially viable on a sustainable basis without government incentives. This is largely in part caused by the cost of generating electricity from solar power currently exceeding and that is expected to continue to exceed the costs of generating electricity from conventional energy sources. The Company generated approximately 88 93 97 A significant portion of the Company’s net revenues are from customers located in the PRC, Japan, the United States of America (“USA”), Turkey, France, Germany and England. Year ended December 31, % of net December 31, % of net % of net 2014 revenue 2015 revenue December 31, 2016 revenue RMB RMB RMB US$ PRC 4,550,915 35 % 4,078,476 41 % 4,932,284 710,397 59 % Japan 2,487,949 19 % 2,723,800 27 % 2,363,239 340,377 28 % USA 2,301,496 18 % 1,248,536 12 % 513,690 73,987 6 % England 998,203 8 % 80,255 1 % 88,129 12,693 1 % Turkey 118,305 1 % 550,799 5 % 69,956 10,076 1 % France 191,071 1 % 363,635 4 % 1,477 213 - Germany 671,534 5 % 170,518 2 % 3,089 445 - Others 1,607,904 13 % 749,767 8 % 404,235 58,221 5 % Total 12,927,377 100 % 9,965,786 100 % 8,376,099 1,206,409 100 % The Company derived significant revenue from sales outside of the PRC. As a result, the Company’s financial performance could be affected by events such as changes in foreign currency exchange rates, trade protection measures and changes in regional or worldwide economic or political conditions. Management currently expects that the Company’s operating results will, for the foreseeable future, continue to depend on the sale of PV modules to a relatively small number of customers. The Company’s relationships with such key customers have been developed over a short period of time and are generally in their preliminary stages. Any factors adversely affecting the business operations of these customers could have a material adverse effect on the Company’s business and results of operations. In 2014, 2015 and 2016, sales to the top five customers accounted for approximately 13.9 19.4 10.7 10 As of December 31, 2015 and 2016, the top five outstanding accounts receivable balances (net of provisions) accounted for approximately 27.6 16.3 12.3 10 Dependence on suppliers Polysilicon is the most important raw material used in the production of the Company’s PV products. To maintain competitive manufacturing operations, the Company depends on timely delivery by its suppliers of polysilicon in sufficient quantities. The Company’s failure to obtain sufficient quantities of polysilicon in a timely manner could disrupt its operations, prevent it from operating at full capacity or limit its ability to expand as planned, which will reduce the growth of its manufacturing output and revenue. In order to secure a stable supply of polysilicon and other raw materials, the Company makes prepayments to certain suppliers. Such amounts are recorded as prepayments to suppliers, prepayments to related party suppliers (included in “Amounts due from and prepayments to related parties”), and “Long-term prepayments to suppliers” in the Company’s consolidated balance sheets and amounted to RMB 1,212,614 RMB 992,569 142,959 December 31, 2015 2016 Location RMB RMB US$ Supplier A Singapore 224,029 239,327 34,470 Supplier B South Korea 158,613 141,227 20,341 Supplier C Germany 277,392 238,242 34,314 Total 660,034 618,796 89,125 The Company obtains some equipment to be used in its manufacturing process from a small number of selected equipment suppliers. In addition, some equipment has been customized based on the Company’s specifications, is not readily available from multiple vendors and would be difficult to repair or replace. If any of these suppliers were to experience financial difficulties or go out of business, the Company may have difficulties in repairing or replacing its equipment in the event of any damage to the manufacturing equipment or a breakdown of the production process. The Company’s ability to deliver products timely would suffer, which in turn could result in order cancellations and loss of revenue. A supplier’s failure to deliver the equipment in a timely manner with adequate quality and on terms acceptable to the Company could delay its capacity expansion of manufacturing facilities and otherwise disrupt its production schedule or increase its costs of production. The Company made deposits of RMB 81,828 and RMB 78,652 11,328 Concentrations of cash balances held at financial institutions December 31, 2015 December 31, 2016 RMB RMB equivalents equivalents Cash and cash equivalents held by PRC entities Denominated in RMB 296,853 155,174 Denominated in U.S. dollar (US$) 480,052 23,450 Denominated in European monetary unit (EURO) 5,350 337 Denominated in Japanese Yen (JPY) — 11 Denominated in Great Britain Pound (GBP) 5 — Denominated in other currencies: — 178 Cash and cash equivalents held by non-PRC entities Denominated in US$ 200,671 253,089 Denominated in EURO 76,295 24,135 Denominated in JPY 156,147 30,579 Denominated in GBP 8,151 3,563 Denominated in other currencies: 17,225 16,126 Total cash and cash equivalents 1,240,749 506,642 December 31, 2015 December 31, 2016 RMB RMB equivalents equivalents Restricted cash held by PRC entities Denominated in RMB 218,669 165,711 Denominated in US$ 21,768 28,741 Denominated in EURO 8,872 9,137 Denominated in other currencies: — — Restricted cash held by non-PRC entities Denominated in US$ 96,054 148,930 Denominated in EURO 1,455 2,236 Denominated in JPY — 4,768 Denominated in other currencies: 108 2,274 Total restricted cash 346,926 361,797 The bank deposits with financial institutions in the PRC are uninsured by any government authority. To limit exposure to credit risk relating to bank deposits, the Company primarily places bank deposits with large financial institutions in the PRC with acceptable credit rating. As of December 31, 2015 and 2016, the Company had cash balances at one and one PRC individual financial institutions, respectively, that held cash balances in excess of 10 34.4 11.05 (d) Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management of the Company to make a number of estimates and assumptions relating to the reported amounts of assets and liabilities as well as with respect to the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include the fair values of assets acquired and liabilities assumed in business acquisitions, the useful lives of property, plant and equipment and intangibles with definite lives, recoverability of the carrying values of property, plant and equipment, and intangible assets, the fair value of share-based payments, the collectability of accounts receivable, the realizability of inventories, prepayments and deferred income tax assets, the fair values of financial and equity instruments, the accruals for warranty obligations and loss contingency, and provision for inventory purchase commitments. The current economic environment has increased the degree of uncertainty inherent in those estimates and (e) Foreign Currency The Company’s reporting currency is the Renminbi ("RMB"). Assets and liabilities of foreign companies whose functional currency is not RMB are translated into RMB using the exchange rate on the balance sheet date. Revenues and expenses are translated at average rates prevailing during the year. Gains and losses resulting from the translation of financial statements of foreign companies are recorded as a separate component of accumulated other comprehensive income within shareholders' equity. Transactions denominated in currencies other than the functional currency are translated into the functional currency at the exchange rates prevailing at the date of the transaction. Monetary assets and liabilities denominated in foreign currencies are translated into the functional currency using the applicable exchange rates at the balance sheet date. The resulting exchange differences are recorded in “foreign currency exchange gains (losses)” in the Consolidated Statements of comprehensive Loss. Transaction gains and losses resulting from intercompany foreign currency transactions that are of a long-term investment nature are treated in the same manner as translation adjustments and therefore excluded from the determination of net loss. RMB is not freely convertible into foreign currencies. All foreign exchange transactions involving RMB must take place either through the People’s Bank of China (“PBOC”) or other institutions authorized to buy and sell foreign exchange. The exchange rate adopted for the foreign exchange transactions are the rates of exchange quoted by the PBOC. For the convenience of readers, certain 2016 RMB amounts have been translated into U.S. dollar amounts at the rate of RMB 6.943 1.00 (f) Cash, Cash equivalents and Restricted Cash Cash and cash equivalents consist of cash on hand, cash in bank accounts, and interest bearing savings accounts with an initial term of three months or less. Restricted cash of RMB 346,926 361,797 52,109 (g) Accounts Receivable Accounts receivable are recorded at the invoiced amount and do not bear interest. The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. The allowance for doubtful accounts is based on a review of specifically identified accounts and aging data. Judgments are made with respect to the collectability of accounts receivable balances based on historical collection experience, customer specific facts and current economic conditions. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. Sale of Accounts Receivable In 2014 and 2016, the Company entered into agreements to sell without recourse certain accounts receivable to several PRC banks. The buyers were responsible for servicing the receivables. The accounts receivables were determined to be legally isolated from the Company and its creditors, even in the event of bankruptcy or other receivership and the Company had surrendered control over the transferred receivables. As a result, the accounts receivables were considered sold and were therefore derecognized. The Company received proceeds from the sale of accounts receivable of RMB 188,117 7,412 1,068 8,885 357 51 (h) Inventories Inventories are stated at the lower of cost or market. Cost is determined by using the weighted-average cost method. Cost of work-in-progress and finished goods are comprised of direct materials, direct labour, and an allocation of related manufacturing overhead based on normal operating capacity. Adjustments are recorded to write down the carrying amount of any obsolete and excess inventory to its estimated net realizable value. Certain factors could impact the realizable value of inventory, so the Company continually evaluates the recoverability based on assumptions about customer demand and market conditions. The evaluation may take into consideration historical usage, expected demand, anticipated sales price, new product development schedules, the effect new products might have on the sale of existing products, product obsolescence, customer concentrations, and other factors. The write-down is equal to the difference between the cost of inventory and the estimated market value based upon assumptions about future demand and market conditions. If actual market conditions are less favorable than those projected by management, additional inventory write-downs may be required that could negatively impact the Group’s gross margin and operating results. If actual market conditions are more favorable, the Company may have higher gross margin when products that have been previously written down are eventually sold 4,208 31,930 89,147 12,840 (i) Prepayments to Suppliers Advance payments for the future delivery of raw materials are made based on written purchase orders detailing product, quantity, pricing and are classified as “prepayments to suppliers” in the consolidated balance sheets. The Company’s supply contracts grant the Company the right to inspect products prior to acceptance. The amount in the balance of the “prepayments to suppliers” is reclassified to “inventories” when inventory is received and passes quality inspection. Such reclassifications of RMB 340,007 318,132 496,885 71,566 555,520 343,591 49,487 For the years ended December 31, 2014, 2015 and 2016, provisions of nil, RMB 522,050 10,672 1,537 with inventory firm purchase commitment the year ended December 31, 2016, due to several suppliers failing to fulfill their delivery obligations and each was in financial difficulty, after assessment, the Company also made total provision of RMB 113,416 16,335 (j) Long-lived Assets Property, Plant and Equipment Property, plant and equipment are stated at cost. Depreciation is provided over the estimated useful lives of the asset, taking into consideration any estimated residual value, using the straight-line method. When items are retired or otherwise disposed of, income is charged or credited for the difference between net book value and proceeds received thereon. Ordinary maintenance and repairs are charged to expense as incurred, and replacements and betterments are capitalized. Buildings 30 years Machinery and equipment 4 -25 years Furniture and fixtures 3 -5 years Motor vehicles 8 -10 years Depreciation of property, plant and equipment attributable to manufacturing activities is capitalized as part of the cost of inventory production, and expensed to cost of revenues when the inventory is sold. Cost incurred in the construction of new facilities, including progress payments and deposits, interest and other costs relating to the construction, are capitalized and transferred out of construction in progress and into their respective asset categories when the assets are ready for their intended use, at which time depreciation commences. Leases Leases where substantially all the rewards and risks of ownership of assets remain with the leasing company are accounted for as operating leases. Other leases are accounted for as capital leases. Payments made under operating leases, net of any incentives received by the Company from the leasing company, are charged to the consolidated statements of comprehensive loss on a straight-line basis over the lease periods. Leases that qualify as capital leases are recorded at the lower of the fair value of the asset or the present value of the future minimum lease payments over the lease term generally using the Company’s incremental borrowing rate. Assets leased under capital leases are included in property, plant and equipment and generally are depreciated over the lease term. Lease payments under capital leases are recognized as a reduction of the capital lease obligation and interest expense. For a sale-leaseback transaction, an analysis is performed to determine if the Company can record a sale and remove the assets from the balance sheet and recognize the lease; and if so, to determine whether to record the lease as either an operating or capital lease. If the Company has continued involvement beyond a normal lease, the lease is accounted for as a capital lease transaction and the assets and related financing obligation are recognized on the balance sheet. The Company’s assets under the capital lease transaction were derecognized upon sale at the net book value and rebooked at the financed amount; and the differences between the net book value derecognized and the rebooked financed amount of the assets were deferred and amortized over the lease term. Accordingly, the asset is depreciated over its estimated useful life in accordance with the Company’s If the sale-leaseback transactions involve asset other than real estate, those are evaluated to determine whether they are considered integral with real estate, in which case the sale-leaseback rules related to real estate are applied. Refer to note (16) to the consolidated financial statement. Project assets Project assets consist primarily of costs relating to solar power projects in various stages of development that are capitalized prior to the completion of the solar power project. These costs include modules, installation and other development costs. If a project is completed and begins commercial operation prior to entering into a sales agreement, which is at the point when the solar power plant is connected to grids and begins to generate electricity, costs capitalized in the construction of solar power plants under development will be transferred to solar power plants upon completion and when they are ready for its intended use. Any income generated by such project is accounted for as revenue. Depreciation is provided over the estimated useful lives of the projects assets ( 20 25 As of December 31, 2016, project assets with carrying value of RMB 68,104 9,809 603,941 86,986 For the years ended December 31, 2014, 2015 and 2016, revenue related to the projects assets from power generation were RMB 2,015 30,836 31,556 4,545 2,365 37,855 31,847 4,587 Other Intangible Assets Trademarks that have an indefinite useful life are not amortized, but instead are tested for impairment at least annually. Intangible assets, other than trademarks, are amortized on a straight-line basis over the estimated useful lives of the respective assets. Technical know-how 5.5-6 years Customer relationships 5.5-6 years Order backlog 1-1.5 years Short-term supply agreements 0.5 year Impairment of Long-Lived Assets Long-lived assets, such as property, plant, and equipment and intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset or asset group be tested for possible impairment, the Company first compares undiscounted cash flows expected to be generated by that asset or asset group to its carrying value. If the carrying value of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying value exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values and third party independent appraisals, as considered necessary. Intangible assets that are not subject to amortization are tested annually for impairment at December 31, and are tested for impairment more frequently if events and circumstances indicate that the asset might be impaired. For intangible assets that are not subject to amortization, an impairment loss is recognized to the extent that the carrying amount exceeds the asset’s fair value. For the years ended December 31, 2015 and 2016, a total impairment loss against property, plant and equipment amounted to RMB 3,804,116 1,277,373 183,980 Government grant Government grants are recorded in the balance sheet when they are received and that the Company will comply with the conditions attaching to them. Government grants, which are obtained by the Company for the purposes of purchase, construction or acquisition of the long-term assets, will be recorded as “Deferred other income” and included in “Deferred other income” in the Consolidated Balance Sheets and are depreciated or amortized evenly over the useful lives of the related assets. For the years ended December 31, 2014, 2015 and 2016, the Company received government grants of RMB 80,849 74,581 20,981 3,022 49,557 56,935 49,362 7,110 Government grants other than those related to assets, will be recorded as “Deferred other income” and recognized and recorded in “Other income” in the Consolidated Statement of Comprehensive loss in the period in which the related expenses are recognized if the grants are intended to compensate for future expenses or losses, and otherwise recognized and recorded in “Other income” in the Consolidated Statement of Comprehensive loss for the current period if the grants are used to compensate for expenses or losses that have been incurred. (k) Land and Land Use Rights Land represents the cost of land acquired outside the PRC with indefinite useful life. Land use rights represent the cost of rights to use land in the PRC. Land use rights are carried at cost and charged to expense on a straight-line basis over the respective periods of the rights of 45 50 (l) Equity Investments Investments in entities where the Company does not have a controlling financial interest, but has the ability to exercise significant influence over the operating and financial policies of the investees, are accounted for using equity method accounting. Under the equity method accounting, the Company’s share of the investees’ results of operations is included in “Equity in Income/Loss of Affiliates” in the Company’s Consolidated Statements of Comprehensive Loss. Equity investments are accounted for under cost method when the Company does not have the ability to exercise significant influence over the operating and financial policies of the investees. Under the cost method of accounting, the Company records an investment in the equity of an investee as cost, and recognizes as income dividends received that are distributed from net accumulated earnings of the investee since the date of acquisition. The Company does not have available-for-sale investment. In case the Company sells modules to its equity method investee, the profit derived from the transaction is eliminated to the extent of the Company’s shares in that investee, and the income is credited against “Investments in affiliated companies” in the Consolidated Balance Sheets and deferred until the project assets are ultimately sold to external customers. The Company recognizes a loss when there is a loss in value of an equity investment which is other than a temporary decline. The process of assessing and determining whether an impairment on a particular equity investment is other than temporary requires a significant amount of judgment. To determine whether an impairment is other-than-temporary, management considers whether the Company has the ability and intent to hold the investment until recovery and whether evidence indicating the carrying value of the investment is recoverable outweighs evidence to the contrary. Evidence considered in this assessment includes the reasons for the impairment, the severity and duration of the decline in value, any change in value subsequent to year end, and forecasted performance of the investee.

In step one of the impairment analysis, the estimated future undiscounted net cash flows expected to be generated by the assets over their remaining estimated useful lives were based on certain assumptions, such as forecasts of future operating results, gross margin and expected future growth rates. The estimated undiscounted future cash flows generated by the equipment used to produce solar products were less than their carrying value, which required the step two of the impairment test. In the step two of the impairment analysis, the Company estimated the fair value of the long lived assets based on discounted cash flow analysis using market participants’ assumptions, such as forecasts of future operating results, discount rates commensurate with the risk involved, and expected future growth rates. The carrying value of the equipment was reduced to fair value based on the discounted cash flow analysis. As a result, an impairment loss of RMB 3,804,116 1,277,373 183,980 Depreciation expense on property, plant and equipment and project assets was allocated to the following expense items: Year ended December 31, 2014 2015 2016 RMB RMB RMB US$ Cost of revenues 1,292,586 1,086,392 839,005 120,842 Selling expenses 16,475 7,530 5,048 727 General and administrative expenses 48,963 60,268 32,232 4,642 Research and development expenses 30,260 20,515 11,107 1,600 Total depreciation expense 1,388,284 1,174,705 887,392 127,811 For the year ended December 31, 2016, due to the impairment loss of RMB 3,804,116 530.0 76.3 Year ended December 31, 2014 2015 2016 RMB RMB RMB US$ Interest cost capitalized 8,624 37,452 880 127 Interest cost charged against income 1,015,871 977,176 663,217 95,523 Total interest cost incurred 1,024,495 1,014,628 664,097 95,650 As of December 31, 2015 and 2016, the Company had pledged property, plant and equipment with a total carrying amount of RMB 4,001,055 3,182,852 458,426 In December 2014, Yingli China sold certain machinery and equipment with carrying amount of RMB 405,282 400,000 7 403,191 In February 2015, right after Yingli China repaid total instalment of RMB 400,000 300,000 300,000 1,750 300,000 250,000 250,000 28,000 250,000 75,000 175,000 For year ended December 31, 2016, the Company entered in to several agreements with its suppliers to settle the Company’s long ageing payables to these suppliers by transferring the equipment owned by the Company and its subsidiaries.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	(7) Derivative Instruments and Hedging Activities The Company uses foreign currency forward contracts to manage its exposure to foreign currency risks arising from sales denominated in foreign currency and uses interest rate related derivative instruments to manage its exposure related to changes in interest rates on its variable-rate debt instruments. The Company does not speculate using derivative instruments. Foreign Currency The Company’s principal operating subsidiaries, Hainan Yingli New Energy Resources Co., Ltd. (“Hainan Yingli”) and Yingli Energy (China) Co., Ltd. (“Yingli China”) are located in the PRC with the Renminbi being their functional currency, respectively. However, the majority of these two entity’s sales are in currencies other than Renminbi, primarily the EURO and US$. Any depreciation of the EURO or US$ against the Renminbi will generally result in foreign exchange losses and adversely affect the Company’s results of operations. With an aim to reduce its risk exposure, the Company, on a selected basis, enters into forward contracts with financial institutions to forward sell EURO or US$ when it entered into certain sales contracts denominated in EURO or US$ through its PRC operating subsidiaries. Some of these foreign currency forward contracts are qualified as foreign currency cash flow hedges at inception, and thus the change in the fair value of these hedge contracts were initially recognized in accumulated other comprehensive income and reclassified into the consolidated statements of comprehensive loss in the period that the sale of the related hedged item is recognized or when hedge accounting is discontinued if the foreign currency forward contracts are no longer effective in offsetting cash flows attributable to the hedged risk. During the year ended December 31, 2014, the Company entered into foreign currency forward contracts with a notional amount of EURO 31,760 27,000 2,499,200 80,000 30,000 7,100,000 Interest The Company’s exposure to the risk of changes in market interest rates primarily relates to its bank borrowings. To finance its business operation and expansion, the Company’s PRC operating subsidiaries will obtain short-term and long-term bank borrowings. Some of the bank borrowings carry variable interest rates. Interest expenses on these banking borrowings may increase as a result of change in market interest rates. With an aim to reduce its interest rate exposure, the Company entered into one long-term interest rate swap contract, with notional amount of US$ 70,000 Cash Flow Hedge Loss or Gain Recognition Location of Gain Amount of Gain Amount of Gain Reclassified from Reclassified from Recognized in Other Other Other Comprehensive Comprehensive Comprehensive Income into Derivatives in Cash Flow Income Income into Loss Hedging Relationships RMB US$ Loss RMB US$ 2014 Foreign currency contracts (24,117) Foreign currency exchange losses (24,390) 2015 Foreign currency contracts — Foreign currency exchange losses (749) 2016 Foreign currency contracts — — Foreign currency exchange losses — — Other Derivatives Gains (Losses) Recognition Amount of Loss Recognized in Income on Location of Loss Derivative Recognized in Income 2014 2015 2016 on Derivative RMB RMB RMB US$ Derivatives Not Designated as Hedging Instruments Interest rate swap Interest expense (81) — — — Total (81) — — —

The significant unobservable inputs used in the valuation of the fair value of the asset group subject to impairment are as following: · Weighted average cost of capital, or WACC—The WACCs were determined based on a consideration of such factors as risk-free rate, comparative industry risk, equity risk premium, company size and company-specific factors. The Company used WACC of 15 · Comparable companies—In deriving the discounted cash flow and WACCs, which are used as the discount rates under the discounted cash flow, three to four publicly traded solar companies were selected for reference as market participants. (b) Fair Value of Financial Instruments Management used the following methods and assumptions to estimate the fair value of financial instruments at the relevant balance sheet dates: · Short-term financial instruments (cash and cash equivalents, restricted cash, accounts receivable, amounts due from related parties, accounts payable, short-term borrowing, and amounts due to related parties) - cost approximates fair value because of the short maturity period. ⋅ The fair value of past due mid-term notes disclosed above approximates to its carrying amount. As a common practice in China, government normally would take collective efforts to protect state-owned banks' benefits from having non-performing assets. The chance that the Company can avoid from paying the debt in full is very remote, and therefore the Company determined that cost of medium term note should be equal to its fair value where no further discount can be applied. · Long-term debt and long-term payable (included in other liabilities) - fair value is based on the amount of future cash flows associated with each debt instrument discounted at the Company’s current borrowing rate for similar debt instruments with comparable terms. As of December 31, 2015 and 2016, the carrying values of the Company’s long term debt and long-term payable approximate their fair values as all the long-term borrowings carries variable interest rates which approximate rates currently offered by the Company’s bankers for similar debt instruments of comparable maturities.

Inventory Purchase Commitments Disclosure [Abstract]
Inventory Purchase Commitments [Text Block]	(19) Inventory Purchase Commitments Until the third quarter of 2008, an industry-wide shortage of high purity polysilicon coupled with growing demand for PV modules caused the increases of polysilicon prices. In order to ensure the adequate supply of polysilicon, the Company entered into several long-term fixed price supply contracts with Supplier A, B and C from 2006 to 2011 under which the polysilicon would be delivered from 2009 to 2020. However, from the second quarter of 2011, the polysilicon price has decreased significantly as the result of increased polysilicon manufacturing capacity and the pressure from the decreasing average selling price of PV modules. In October 2013, the Company entered into agreements with Supplier B to amend the contract and include a price adjustment mechanism that allows the Company and the vendor to renegotiate purchase price on a quarterly basis within a specified price range set forth in the amendments based on market price. (a) The inventory firm purchase commitment with Supplier A for the years ended December 31, 2014, 2015 and 2016 As of December 31, 2013, the total liability recognized for loss on inventory purchase commitments of RMB 1,244,743 87,134 In the years ended December 31, 2014, 2015 and 2016, after management’s assessment by using the same methodology mentioned above, no additional contingency losses for inventory firm purchase commitment with Supplier A was determined to be required. However, due to significant fluctuation in the foreign exchange rates between the RMB and US$ in 2015 and 2016 and given that the inventory purchase commitment to Supplier A is dominated in US dollar, which is different from the related entities’ functional currency, a foreign exchange re-measurement loss of RMB 77,705 90,300 13,006 As of December 31, 2014, 2015 and 2016, the total reserve for inventory purchase commitment of Supplier A was RMB 1,244,743 1,322,448 1,412,748 203,478 13,042 1,231,701 1,322,448 1,412,748 203,478 Year ended December 31, 2014 2015 2016 RMB RMB RMB US$ Beginning balance (1,244,743) (1,244,743) (1,322,448) (190,472) Additions — (77,705) (90,300) (13,006) Ending balance (1,244,743) (1,322,448) (1,412,748) (203,478) In entering into its inventory purchase contracts with Supplier A, the Company made prepayments as described in note 2(c). As of December 31, 2015 and 2016, total balance of prepayments made to Supplier A was RMB 224,029 239,327 34,500 1.6 (b) The inventory firm purchase commitment with Supplier C for the years ended December 31, 2014, 2015 and 2016 As described in note 2(c), the Company also has prepayments with respect to another supplier, Supplier C, for the purchase of polysilicon. As of December 31, 2013, a provision of RMB 87,134 In 2015, the Company failed to purchase from Supplier C the stated quantities under the long-term fixed price supply contracts as the Company’s management determined after taking into consideration all relevant factors that it would be in the Company’s best interest not to accept those deliveries when they were due. As a result, because the contract has been substantially executed, the vendor claimed that certain advance payments had been forfeited. Unlike the take or pay obligation for Supplier A described in Note 18(a), if the Company fails to take the full amount of the agreed annual quantity in any calendar year, the Company does not have to pay for the remaining annual commitment, but rather only forfeits the unutilized portion of the prepayment related to that year. Further, the Company does not have the right to utilize this prepayment for deliveries in the following years. Accordingly, a provision of RMB 71,266 For year ended December 31, 2016, the Company made an additional true-up provision of RMB 10,672 1,537 Year ended December 31, 2014 2015 2016 RMB RMB RMB US$ Beginning balance (87,134) (87,134) (609,184) (87,741) Additions — (522,050) (10,672) (1,537) Ending balance (87,134) (609,184) (619,856) (89,278) As of December 31, 2015 and 2016, total impairment provided against prepayments to Supplier C in relation to inventory purchase commitments was RMB 609,184 619,856 89,278 238,242 34,314

Commitments and Contingencies Disclosure [Text Block]	Commitments and Contingencies (a) Commitments As of December 31, 2016, commitments outstanding for the purchase of property, plant and equipment approximated RMB 1,510.8 217.6 In order to secure adequate and timely supply of polysilicon, the Company entered into a number of multi-year supply agreements from 2006 through 2011. Year ended December 31, RMB US$ 2017 349,625 50,356 2018 1,539,797 221,777 2019 2,078,637 299,386 2010 2,078,637 299,386 2021 2,078,637 299,386 Thereafter 7,517,867 1,082,798 Total 15,643,200 2,253,089 The purchase prices under the multi-year supply agreements are subject to adjustments, taking into consideration the spot market price, the cost to produce the polysilicon, among other things. The Company purchased polysilicon from Supplier B in the amount of RMB 561,487 461,515 238,182 34,305 Besides the “take or pay” arrangements, future minimum obligations under other polysilicon supply agreements with Supplier C amounted to RMB 2,977,423 428,838 701,784 248,496 219,991 31,685 522,050 10,672 1,537 In terms of the supply agreement with Supplier A, it is impractical for the Company to execute the agreement because of the events such as anti-dumping and anti-subsidy investigations into solar-grade polysilicon imported from the U.S. and South Korea launched by the Ministry of Commerce of the PRC in July 2012 that have occurred are beyond the management’s control. Therefore, based on assessment of management, no material losses or costs should be incurred for not executing the agreement. Reserve for inventory purchase commitments was provided against Supplier A for year ended December 31, 2016, please refer to note (19). (b) Contingencies In the past years, the Company signed several agreements and amendments with a supplier to provide certain service for the Company. Due to certain quality control issues related to the supplier and substantial changes in the market, the Company and this supplier had disputes over the performance of the contracts and the Company's payments of accounts receivable to the supplier. In May 2013, the supplier informed the Company that it would like to cease the recovery service and claimed compensation. In July 2014, the Company filed litigation against this supplier for breach of contract and claimed damages against this supplier. In September 2015, the supplier also filed litigation against the Company for the default in performance of contract and claimed compensation. The Provincial High People’s Court consolidated these two disputes in January 2016, in accordance with the Company’s request. At the end of December 2016, the court issued judgments as to these two disputes and the Company was informed of the judgments in January 2017, in which the court ruled that the agreements and amendments with the supplier shall be rescinded, and the Company shall pay compensation to the supplier. All other claims of the Company and the supplier were rejected. At this time, both the Company and the supplier have appealed to the Supreme People’s Court, so no judgments of the Provincial High People’s Court have yet taken effect. The Supreme People’s Court has not held any hearing yet. The Company believes that the supplier’s claims lack merit. As such, the Company is hopeful that the judgment from the Provincial High People’s Court will be overturned in the Company’s favor. However, considering the uncertainties involved in the appeals process, the Company made a provision of RMB 59 In October 2013, the Company received notice of an antitrust filed by Energy Conversion Devices Liquidation Trust (“ECD”), through its liquidating trustee, against the Company and two other China-based photovoltaic panel manufacturers. in the U.S. District Court of the Eastern District of Michigan. ECD alleges a wide-ranging conspiracy among the Company and other two Chinese photovoltaic panel manufacturers, their suppliers, banks and the Chinese government to destroy ECD and the U.S. solar industry by flooding the market with cheap photovoltaic panels. On October 31, 2014, the Court granted the Company’s joint motion to dismiss the case. In November 2014, the plaintiff filed a motion for reconsideration and a second motion to amend or alter the judgement and for leave to file an amended complaint, both of which were denied by the Court in September 2015. ECD appealed to the U.S. Court of Appeals for the Sixth Circuit, which unanimously affirmed the trial court’s dismissal of ECD’s claims in August 2016. ECD filed a petition for a writ of certiorari to the U.S. Supreme Court, which was denied on April 17, 2017, ending the litigation. In May and June 2015, two individual plaintiffs respectively filed purported class action securities fraud lawsuits against the Company, the Company’s chairperson and chief executive officer, Mr. Liansheng Miao, and our director and chief executive officer, Mr. Yiyu Wang, in the U.S. District Court for the Central District of California, both alleging, among other things, that the Company made false and misleading statements and failed to disclose certain material financial information. In October 2015, the cases were consolidated, and the court appointed lead plaintiffs and lead counsel. In November 2015, lead plaintiffs filed a consolidated amended complaint. The amended complaint contended that the Company and certain of the Company’s officers and directors made false or misleading statements between December 2, 2010 and May 15, 2015 regarding (i) the Chinese government’s Golden Sun program, which provided subsidies for solar projects in China; and (ii) the Company’s accounts receivable attributable to Chinese customers. The sole claim in that complaint was for violation of Section 10(b) of the Securities Exchange Act of 1934. In December 2015, the Company filed a motion to dismiss the consolidated suit, and, on May 10, 2016, the Court granted that motion with leave to amend. On June 24, 2016, lead plaintiffs filed a new complaint, again alleging that, between December 2, 2010 and May 15, 2015, Yingli’s officers made false or misleading statements regarding Golden Sun and accounts receivables. This complaint added an additional claim against Mr. Miao and Mr. Wang for violation of Section 20(a) of the Exchange Act. On August 8, 2016, the Company again filed a motion to dismiss the suit, and, on March 15, 2017, the Court again dismissed the plaintiffs’ claims with leave to amend. The plaintiffs filed a second amended complaint on April 24, 2017. The Court set a briefing schedule requiring the filing of the Company’s motion to dismiss by May 30, 2017, plaintiffs’ opposition by July 5, 2017, and the Company’s reply by July 19, 2017. A hearing on the motion is set for August 14, 2017. It is premature at this stage of the litigation to evaluate the likelihood of favorable or unfavorable outcomes. The Company intend to defend vigorously against those allegations. In October 2012, the Company received notice of an antitrust and unfair competition lawsuit filed by Solyndra, LLC (“Solyndra”, a U.S.-based solar company) against the Company and two other China-based photovoltaic panel manufacturers in the U.S. District Court of the Northern District of California. The Company filed its joint motion to dismiss all of Solyndra’s claims with the co-defendants in March 2013. On April 9, 2014, the Company received an order denying defendants’ joint motion to dismiss Solyndra’s claims. In February 2016, the Company entered into an agreement to settle these claims (“the Settlement Agreement”). According to the Settlement Agreement, i) the Company together with Yingli Green Energy Americas, Inc. (“Yingli Americas”, one subsidiaries of the Company), shall pay US$ 7.5 7.5 48.7 10 64.8 7.5

These technologies included the design and configuration of the Company’s PV manufacturing line, manufacturing technologies and process for high efficiency silicon solar cells and provision of innovations for continuous improvement of cell efficiencies and manufacturing cost reduction. Management estimated that the economic useful life of technical know-how by taking into consideration of the remaining life cycle of the current manufacturing technologies. Management estimated the useful life of the customer relationships based primarily on the historical experience of the Company’s customer attrition rate and estimated sales to these customers in future years. The straight-line method of amortization has been adopted as the pattern in which the economic benefit of the customer relationship are used, cannot be reliably determined. The estimated fair values of short-term and long-term supply agreements were determined based on the present values of the after-tax cost savings of the Company’s short-term and long-term supply agreements. The after-tax cost savings of the Company’s short-term and long-term supply agreements were based on the difference of price of polysilicon between the agreed purchase price per the supply contracts and the forecasted spot market price at time of the forecasted inventory acquisition. The after-tax costs savings also considered the interest impact of making the pre-payments in accordance with the supply agreements payment terms. Management estimated the useful life of the short-term and long-term supply agreements based upon the contractual delivery periods specified in each agreement. The long-term supply agreements relate to four long-term polysilicon supply agreements with delivery period commencing in 2009.

Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	(a) Basis of Presentation The accompanying consolidated financial statements of the Company have been prepared and presented in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The realization of assets and the satisfaction of liabilities in the normal course of business are dependent on, among other things, the Company’s ability to operate profitably and to generate cash flows from operations, and the ability to pursue financing arrangements, including the renewal or rollover of its bank borrowings, to support its working capital requirements and its obligations and commitments on loans and borrowings when they become due. The following factors raise substantial doubt about the Company’s ability to continue as a going concern: ⋅ For the year ended December 31, 2016, the Company incurred a net loss of RMB 2,118,969 305,195 ⋅ As of December 31, 2016, the Company had a total deficit attributable to the Company of RMB 15,428,426 2,222,156 7,471,576 1,076,131 ⋅ As of December 31, 2016, the Company had cash, cash equivalents and restricted cash of RMB 868,439 125,081 9,010,205 1,297,739 2,523,621 363,477 ⋅ As of December 31, 2016 and from the date of issuance of these statements, Baoding Tianwei Yingli New Energy Resources Co., Ltd. (“Tianwei Yingli”), one of the Company’s major manufacturing subsidiaries, had RMB 1,943,707 279,952 1,993,518 287,126 ⋅ As of December 31, 2016 and from the date of issuance of these statements, the Company had RMB 222,331 32,022 190,967 27,505 ⋅ As of December 31, 2016, except for those loans and debts mentioned above, total short term loans expected to be repaid within one year is RMB 7,080,959 1,019,870 The liquidity of the Company is primarily dependent on its ability to generate adequate cash flows from operations, to renew or rollover its short-term borrowings and to obtain adequate external financings to support its working capital and meet its obligations and commitments when they become due. The Company has carried out a review of its cash flow forecast for the twelve months from the date of issuance of these statements. In preparing the cash flow forecast, the Company's management has considered historical cash requirements of the Company, the Company's expected debt repayment obligations in 2017 and beyond, the Company’s plan to further reduce operating costs and expenses, the Company's plan to receive cash from disposal of certain equity investments, as well as the alternative financing plans discussed in detail below. The Company's management also made the assumption about the numbers of shipments of modules and gross profit margin. The Company is currently exploring a variety of alternative financing plans to improve the Company’s liquidity and financial position as follows: Form a Special Committee and Introducing Strategic Investors The Company issued a press release on March 7, 2017 and stated that, in order to properly consider the Company's options with respect to and ultimately resolve the debt repayment issues faced by the Company's principal subsidiaries, the Company's board of directors has formed a special committee (the "Special Committee") comprised solely of independent directors to assess the Company's operating and financial situation and evaluate, develop and recommend one or more strategic alternatives and financing plans potentially workable to the Company in order to improve its debt structure. The Company is also in negotiation proactively with certain investors for potential strategic investments in the Company or its major subsidiaries. Such financing plan and strategic investments, if successfully completed, will further increase the liquidity of the Company and improve its debt-to-equity ratio. Debt Restructuring On May 3, 2017, the Company has paid the RMB 300 1,757,000 Out of the total RMB 1,757,000, medium-term notes of RMB 357,000 October 13, 2015 1,400,000 May 12, 2016 Also, as part of the Company’s plan to improve liquidity, for year ended December 31, 2016, the Company successfully negotiated with certain suppliers, and these suppliers agreed to waive partial amount of the long ageing accounts payables. Total amount waived by the suppliers in 2016 as a result of the settlement was RMB 22,165 (US$ 3,192) Renewal or Rollover of Borrowings and other Financing Arrangements The Company has maintained good relationships with its lending banks and other financial institutions in China. While there can be no assurance that the Company will be able to refinance its short-term borrowings as they become due, historically, the Company has renewed or rolled over most of its short-term bank and other borrowings upon their maturity dates and has assumed it will continue to be able to do so. As of March 31, 2017, the Company has successfully renewed or rolled over RMB 255.7 36.8 In addition, the Company has obtained financing through other arrangements, such as failed sale and lease back of certain machinery and equipment and financing in the form of sale and repurchase of certain equity interest in its subsidiary, in substance, they are financing in nature and recorded as liabilities. Based on the management’s assessment, there can be no assurance, however, that such expected financing plans will be successfully completed on terms acceptable to the Company, or effectively implemented within one year after the date that the consolidated financial statements are issued, or when implemented, it will mitigate the relevant conditions or events that raise substantial doubt about the Company's ability to continue as a going concern. The Company’s financing plans for its continuing operations, even if successful, may not result in sufficient cash flow to finance and maintain its business. Facts and circumstances including recurring losses, negative working capital, net cash outflows, and uncertainties on the repayment of the debts raise substantial doubt about the Company’s ability to continue as a going concern. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.
Consolidation, Policy [Policy Text Block]	(b) Principles of Consolidation The accompanying consolidated financial statements include the accounts of Yingli Green Energy and its subsidiaries. For consolidated subsidiaries where the Company’s ownership in the subsidiary is less than 100 The Company applies the guidance codified in Accounting Standard Codification 810, Consolidations (“ASC 810”) on accounting for VIEs and their respective subsidiaries, which requires certain variable interest entities to be consolidated by the primary beneficiary of the entity in which it has a controlling financial interest. A VIE is an entity with one or more of the following characteristics: (a) the total equity investment at risk is not sufficient to permit the entity to finance its activities without additional financial support; (b) as a group, the holders of the equity investment at risk lack the ability to make certain decisions, the obligation to absorb expected losses or the right to receive expected residual returns, or (c) an equity investor has voting rights that are disproportionate to its economic interest and substantially all of the entity’s activities are on behalf of the investor. Accordingly, the financial statements of the VIEs and VIEs’ subsidiaries are consolidated into the Company’s financial statements. In 2014, the Company signed several contracts with Yingli PV Investment Group Co., Ltd. (“Yingli PV Group”) to construct all project assets on behalf of the Company. Each project asset is owned by a special purpose entity which is owned 100% by Yingli PV Group. According to the aforementioned contracts, 1) The Company could claim the ownership of these PV projects at any time during the PV project construction progress by demanding Yingli PV Group to transfer its 100 In 2014, the Company entered into two separate agreements with a related party to dispose the Company’s 100% equity interest in two subsidiaries. The disposal gain of RMB 23,943 146,606 122,663 182,286 59,623 In September 2015, the Company entered into an agreement with Yingli PV Group to terminate the above-mentioned construction contracts and the Company was no longer entitled to any rights or undertook any obligations under the aforementioned contracts. As a result, the Company disposed all the project assets under the VIE structure to Yingli PV Group. Total consideration for disposal of all entities under the VIE structure was RMB 554,452 6,852 561,304 1,886,045 1,324,741 In 2015, the Company entered into three separate agreements with three entities unrelated to the Company to dispose the Company’s 100 28,430 4,389 30,002 4,631 1,572 243 180,752 179,180 In 2016, the Company entered into four separate agreements with two entities unrelated to the Company, and two related parties to dispose the Company’s 100 34,339 4,946 5,026 724 29,332 29,313 4,222 53,411 82,724
Concentration Risk Credit Risk [Policy Text Block]	(c) Significant Concentrations and Risks Revenue concentrations The Company’s business depends substantially on government incentives given to its customers. In many countries in which the Company sells its products, the market of the Company’s products would not be commercially viable on a sustainable basis without government incentives. This is largely in part caused by the cost of generating electricity from solar power currently exceeding and that is expected to continue to exceed the costs of generating electricity from conventional energy sources. The Company generated approximately 88 93 97 A significant portion of the Company’s net revenues are from customers located in the PRC, Japan, the United States of America (“USA”), Turkey, France, Germany and England.

As a result, the Company’s financial performance could be affected by events such as changes in foreign currency exchange rates, trade protection measures and changes in regional or worldwide economic or political conditions. Management currently expects that the Company’s operating results will, for the foreseeable future, continue to depend on the sale of PV modules to a relatively small number of customers. The Company’s relationships with such key customers have been developed over a short period of time and are generally in their preliminary stages. Any factors adversely affecting the business operations of these customers could have a material adverse effect on the Company’s business and results of operations. In 2014, 2015 and 2016, sales to the top five customers accounted for approximately 13.9 19.4 10.7 10 As of December 31, 2015 and 2016, the top five outstanding accounts receivable balances (net of provisions) accounted for approximately 27.6 16.3 12.3 10 Dependence on suppliers Polysilicon is the most important raw material used in the production of the Company’s PV products. To maintain competitive manufacturing operations, the Company depends on timely delivery by its suppliers of polysilicon in sufficient quantities. The Company’s failure to obtain sufficient quantities of polysilicon in a timely manner could disrupt its operations, prevent it from operating at full capacity or limit its ability to expand as planned, which will reduce the growth of its manufacturing output and revenue. In order to secure a stable supply of polysilicon and other raw materials, the Company makes prepayments to certain suppliers. Such amounts are recorded as prepayments to suppliers, prepayments to related party suppliers (included in “Amounts due from and prepayments to related parties”), and “Long-term prepayments to suppliers” in the Company’s consolidated balance sheets and amounted to RMB 1,212,614 RMB 992,569 142,959 December 31, 2015 2016 Location RMB RMB US$ Supplier A Singapore 224,029 239,327 34,470 Supplier B South Korea 158,613 141,227 20,341 Supplier C Germany 277,392 238,242 34,314 Total 660,034 618,796 89,125 The Company obtains some equipment to be used in its manufacturing process from a small number of selected equipment suppliers. In addition, some equipment has been customized based on the Company’s specifications, is not readily available from multiple vendors and would be difficult to repair or replace. If any of these suppliers were to experience financial difficulties or go out of business, the Company may have difficulties in repairing or replacing its equipment in the event of any damage to the manufacturing equipment or a breakdown of the production process. The Company’s ability to deliver products timely would suffer, which in turn could result in order cancellations and loss of revenue. A supplier’s failure to deliver the equipment in a timely manner with adequate quality and on terms acceptable to the Company could delay its capacity expansion of manufacturing facilities and otherwise disrupt its production schedule or increase its costs of production. The Company made deposits of RMB 81,828 and RMB 78,652 11,328 Concentrations of cash balances held at financial institutions Cash balances include: December 31, 2015 December 31, 2016 RMB RMB equivalents equivalents Cash and cash equivalents held by PRC entities Denominated in RMB 296,853 155,174 Denominated in U.S. dollar (US$) 480,052 23,450 Denominated in European monetary unit (EURO) 5,350 337 Denominated in Japanese Yen (JPY) — 11 Denominated in Great Britain Pound (GBP) 5 — Denominated in other currencies: — 178 Cash and cash equivalents held by non-PRC entities Denominated in US$ 200,671 253,089 Denominated in EURO 76,295 24,135 Denominated in JPY 156,147 30,579 Denominated in GBP 8,151 3,563 Denominated in other currencies: 17,225 16,126 Total cash and cash equivalents 1,240,749 506,642 December 31, 2015 December 31, 2016 RMB RMB equivalents equivalents Restricted cash held by PRC entities Denominated in RMB 218,669 165,711 Denominated in US$ 21,768 28,741 Denominated in EURO 8,872 9,137 Denominated in other currencies: — — Restricted cash held by non-PRC entities Denominated in US$ 96,054 148,930 Denominated in EURO 1,455 2,236 Denominated in JPY — 4,768 Denominated in other currencies: 108 2,274 Total restricted cash 346,926 361,797 The bank deposits with financial institutions in the PRC are uninsured by any government authority. To limit exposure to credit risk relating to bank deposits, the Company primarily places bank deposits with large financial institutions in the PRC with acceptable credit rating. As of December 31, 2015 and 2016, the Company had cash balances at one and one PRC individual financial institutions, respectively, that held cash balances in excess of 10 34.4 11.05
Use of Estimates, Policy [Policy Text Block]	(d) Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management of the Company to make a number of estimates and assumptions relating to the reported amounts of assets and liabilities as well as with respect to the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include the fair values of assets acquired and liabilities assumed in business acquisitions, the useful lives of property, plant and equipment and intangibles with definite lives, recoverability of the carrying values of property, plant and equipment, and intangible assets, the fair value of share-based payments, the collectability of accounts receivable, the realizability of inventories, prepayments and deferred income tax assets, the fair values of financial and equity instruments, the accruals for warranty obligations and loss contingency, and provision for inventory purchase commitments. The current economic environment has increased the degree of uncertainty inherent in those estimates and
Foreign Currency Transactions and Translations Policy [Policy Text Block]	(e) Foreign Currency The Company’s reporting currency is the Renminbi ("RMB"). Assets and liabilities of foreign companies whose functional currency is not RMB are translated into RMB using the exchange rate on the balance sheet date. Revenues and expenses are translated at average rates prevailing during the year. Gains and losses resulting from the translation of financial statements of foreign companies are recorded as a separate component of accumulated other comprehensive income within shareholders' equity. Transactions denominated in currencies other than the functional currency are translated into the functional currency at the exchange rates prevailing at the date of the transaction. Monetary assets and liabilities denominated in foreign currencies are translated into the functional currency using the applicable exchange rates at the balance sheet date. The resulting exchange differences are recorded in “foreign currency exchange gains (losses)” in the Consolidated Statements of comprehensive Loss. Transaction gains and losses resulting from intercompany foreign currency transactions that are of a long-term investment nature are treated in the same manner as translation adjustments and therefore excluded from the determination of net loss. RMB is not freely convertible into foreign currencies. All foreign exchange transactions involving RMB must take place either through the People’s Bank of China (“PBOC”) or other institutions authorized to buy and sell foreign exchange. The exchange rate adopted for the foreign exchange transactions are the rates of exchange quoted by the PBOC. For the convenience of readers, certain 2016 RMB amounts have been translated into U.S. dollar amounts at the rate of RMB 6.943 1.00
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block]	(f) Cash, Cash equivalents and Restricted Cash Cash and cash equivalents consist of cash on hand, cash in bank accounts, and interest bearing savings accounts with an initial term of three months or less. Restricted cash of RMB 346,926 361,797 52,109
Receivables, Policy [Policy Text Block]	(g) Accounts Receivable Accounts receivable are recorded at the invoiced amount and do not bear interest. The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. The allowance for doubtful accounts is based on a review of specifically identified accounts and aging data. Judgments are made with respect to the collectability of accounts receivable balances based on historical collection experience, customer specific facts and current economic conditions. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. Sale of Accounts Receivable In 2014 and 2016, the Company entered into agreements to sell without recourse certain accounts receivable to several PRC banks. The buyers were responsible for servicing the receivables. The accounts receivables were determined to be legally isolated from the Company and its creditors, even in the event of bankruptcy or other receivership and the Company had surrendered control over the transferred receivables. As a result, the accounts receivables were considered sold and were therefore derecognized. The Company received proceeds from the sale of accounts receivable of RMB 188,117 7,412 1,068 8,885 357 51
Inventory, Policy [Policy Text Block]	(h) Inventories Inventories are stated at the lower of cost or market. Cost is determined by using the weighted-average cost method. Cost of work-in-progress and finished goods are comprised of direct materials, direct labour, and an allocation of related manufacturing overhead based on normal operating capacity. Adjustments are recorded to write down the carrying amount of any obsolete and excess inventory to its estimated net realizable value. Certain factors could impact the realizable value of inventory, so the Company continually evaluates the recoverability based on assumptions about customer demand and market conditions. The evaluation may take into consideration historical usage, expected demand, anticipated sales price, new product development schedules, the effect new products might have on the sale of existing products, product obsolescence, customer concentrations, and other factors. The write-down is equal to the difference between the cost of inventory and the estimated market value based upon assumptions about future demand and market conditions. If actual market conditions are less favorable than those projected by management, additional inventory write-downs may be required that could negatively impact the Group’s gross margin and operating results. If actual market conditions are more favorable, the Company may have higher gross margin when products that have been previously written down are eventually sold 4,208 31,930 89,147 12,840
Prepayments To Suppliers [Policy Text Block]	(i) Prepayments to Suppliers Advance payments for the future delivery of raw materials are made based on written purchase orders detailing product, quantity, pricing and are classified as “prepayments to suppliers” in the consolidated balance sheets. The Company’s supply contracts grant the Company the right to inspect products prior to acceptance. The amount in the balance of the “prepayments to suppliers” is reclassified to “inventories” when inventory is received and passes quality inspection. Such reclassifications of RMB 340,007 318,132 496,885 71,566 555,520 343,591 49,487 For the years ended December 31, 2014, 2015 and 2016, provisions of nil, RMB 522,050 10,672 1,537 with inventory firm purchase commitment the year ended December 31, 2016, due to several suppliers failing to fulfill their delivery obligations and each was in financial difficulty, after assessment, the Company also made total provision of RMB 113,416 16,335
Impairment or Disposal of Long-Lived Assets, Including Intangible Assets, Policy [Policy Text Block]	(j) Long-lived Assets Property, Plant and Equipment Property, plant and equipment are stated at cost. Depreciation is provided over the estimated useful lives of the asset, taking into consideration any estimated residual value, using the straight-line method. When items are retired or otherwise disposed of, income is charged or credited for the difference between net book value and proceeds received thereon. Ordinary maintenance and repairs are charged to expense as incurred, and replacements and betterments are capitalized. Buildings 30 years Machinery and equipment 4 -25 years Furniture and fixtures 3 -5 years Motor vehicles 8 -10 years Depreciation of property, plant and equipment attributable to manufacturing activities is capitalized as part of the cost of inventory production, and expensed to cost of revenues when the inventory is sold. Cost incurred in the construction of new facilities, including progress payments and deposits, interest and other costs relating to the construction, are capitalized and transferred out of construction in progress and into their respective asset categories when the assets are ready for their intended use, at which time depreciation commences. Leases Leases where substantially all the rewards and risks of ownership of assets remain with the leasing company are accounted for as operating leases. Other leases are accounted for as capital leases. Payments made under operating leases, net of any incentives received by the Company from the leasing company, are charged to the consolidated statements of comprehensive loss on a straight-line basis over the lease periods. Leases that qualify as capital leases are recorded at the lower of the fair value of the asset or the present value of the future minimum lease payments over the lease term generally using the Company’s incremental borrowing rate. Assets leased under capital leases are included in property, plant and equipment and generally are depreciated over the lease term. Lease payments under capital leases are recognized as a reduction of the capital lease obligation and interest expense. For a sale-leaseback transaction, an analysis is performed to determine if the Company can record a sale and remove the assets from the balance sheet and recognize the lease; and if so, to determine whether to record the lease as either an operating or capital lease. If the Company has continued involvement beyond a normal lease, the lease is accounted for as a capital lease transaction and the assets and related financing obligation are recognized on the balance sheet. The Company’s assets under the capital lease transaction were derecognized upon sale at the net book value and rebooked at the financed amount; and the differences between the net book value derecognized and the rebooked financed amount of the assets were deferred and amortized over the lease term. Accordingly, the asset is depreciated over its estimated useful life in accordance with the Company’s When the assets transaction does not qualify as a sale-leaseback transaction, it will be treated as a financing transaction. If the sale-leaseback transactions involve asset other than real estate, those are evaluated to determine whether they are considered integral with real estate, in which case the sale-leaseback rules related to real estate are applied. Refer to note (16) to the consolidated financial statement. Project assets Project assets consist primarily of costs relating to solar power projects in various stages of development that are capitalized prior to the completion of the solar power project. These costs include modules, installation and other development costs. If a project is completed and begins commercial operation prior to entering into a sales agreement, which is at the point when the solar power plant is connected to grids and begins to generate electricity, costs capitalized in the construction of solar power plants under development will be transferred to solar power plants upon completion and when they are ready for its intended use. Any income generated by such project is accounted for as revenue. Depreciation is provided over the estimated useful lives of the projects assets ( 20 25 As of December 31, 2016, project assets with carrying value of RMB 68,104 9,809 603,941 86,986 For the years ended December 31, 2014, 2015 and 2016, revenue related to the projects assets from power generation were RMB 2,015 30,836 31,556 4,545 2,365 37,855 31,847 4,587 Other Intangible Assets Trademarks that have an indefinite useful life are not amortized, but instead are tested for impairment at least annually. Intangible assets, other than trademarks, are amortized on a straight-line basis over the estimated useful lives of the respective assets. Technical know-how 5.5-6 years Customer relationships 5.5-6 years Order backlog 1-1.5 years Short-term supply agreements 0.5 year Impairment of Long-Lived Assets Long-lived assets, such as property, plant, and equipment and intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset or asset group be tested for possible impairment, the Company first compares undiscounted cash flows expected to be generated by that asset or asset group to its carrying value. If the carrying value of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying value exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values and third party independent appraisals, as considered necessary. Intangible assets that are not subject to amortization are tested annually for impairment at December 31, and are tested for impairment more frequently if events and circumstances indicate that the asset might be impaired. For intangible assets that are not subject to amortization, an impairment loss is recognized to the extent that the carrying amount exceeds the asset’s fair value. For the years ended December 31, 2015 and 2016, a total impairment loss against property, plant and equipment amounted to RMB 3,804,116 1,277,373 183,980 Government grant Government grants are recorded in the balance sheet when they are received and that the Company will comply with the conditions attaching to them. Government grants, which are obtained by the Company for the purposes of purchase, construction or acquisition of the long-term assets, will be recorded as “Deferred other income” and included in “Deferred other income” in the Consolidated Balance Sheets and are depreciated or amortized evenly over the useful lives of the related assets. For the years ended December 31, 2014, 2015 and 2016, the Company received government grants of RMB 80,849 74,581 20,981 3,022 49,557 56,935 49,362 7,110 Government grants other than those related to assets, will be recorded as “Deferred other income” and recognized and recorded in “Other income” in the Consolidated Statement of Comprehensive loss in the period in which the related expenses are recognized if the grants are intended to compensate for future expenses or losses, and otherwise recognized and recorded in “Other income” in the Consolidated Statement of Comprehensive loss for the current period if the grants are used to compensate for expenses or losses that have been incurred.
Land and Land Use Rights [Policy Text Block]	(k) Land and Land Use Rights Land represents the cost of land acquired outside the PRC with indefinite useful life. Land use rights represent the cost of rights to use land in the PRC. Land use rights are carried at cost and charged to expense on a straight-line basis over the respective periods of the rights of 45 50
Equity Method Investments, Policy [Policy Text Block]	(l) Equity Investments Investments in entities where the Company does not have a controlling financial interest, but has the ability to exercise significant influence over the operating and financial policies of the investees, are accounted for using equity method accounting. Under the equity method accounting, the Company’s share of the investees’ results of operations is included in “Equity in Income/Loss of Affiliates” in the Company’s Consolidated Statements of Comprehensive Loss. Equity investments are accounted for under cost method when the Company does not have the ability to exercise significant influence over the operating and financial policies of the investees. Under the cost method of accounting, the Company records an investment in the equity of an investee as cost, and recognizes as income dividends received that are distributed from net accumulated earnings of the investee since the date of acquisition. The Company does not have available-for-sale investment. In case the Company sells modules to its equity method investee, the profit derived from the transaction is eliminated to the extent of the Company’s shares in that investee, and the income is credited against “Investments in affiliated companies” in the Consolidated Balance Sheets and deferred until the project assets are ultimately sold to external customers. The Company recognizes a loss when there is a loss in value of an equity investment which is other than a temporary decline. The process of assessing and determining whether an impairment on a particular equity investment is other than temporary requires a significant amount of judgment. To determine whether an impairment is other-than-temporary, management considers whether the Company has the ability and intent to hold the investment until recovery and whether evidence indicating the carrying value of the investment is recoverable outweighs evidence to the contrary. Evidence considered in this assessment includes the reasons for the impairment, the severity and duration of the decline in value, any change in value subsequent to year end, and forecasted performance of the investee.
Statutory Reserves [Policy Text Block]	(m) Statutory Reserves In accordance with the relevant laws and regulations of the PRC, PRC enterprises are required to transfer 10 50 500,164 500,719 72,119
Derivatives, Policy [Policy Text Block]	(n) Derivative Financial Instruments and Hedging Activities The Company recognizes all derivative instruments as either assets or liabilities in the balance sheet at their respective fair values. For derivatives designated in hedging relationships, changes in the fair value are either offset through earnings against the change in fair value of the designated hedged item attributable to the risk being hedged or recognized in accumulated other comprehensive income, to the extent the derivative is effective at offsetting the changes in cash flows being hedged until the hedged item affects earnings. The Company enters into derivative contracts that it intends to designate as a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (cash flow hedge). For all hedging relationships, the Company formally documents the hedging relationship and its risk management objective and strategy for undertaking the hedge, the hedging instrument, the hedged transaction, the nature of the risk being hedged, how the hedging instrument’s effectiveness in offsetting the hedged risk will be assessed prospectively and retrospectively, and a description of the method used to measure ineffectiveness. The Company also formally assesses, both at the inception of the hedging relationship and on an ongoing basis, whether the derivatives that are used in hedging relationships are highly effective in offsetting changes in cash flows of hedged transactions. For derivative instruments that are designated and qualify as part of a cash flow hedging relationship, the effective portion of the gain or loss on the derivative is reported as a component of other comprehensive income and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings. The maximum term over which the Company is hedging exposures to the variability of cash flows for forecasted transaction is 12 months. The Company discontinues hedge accounting prospectively when it determines that the derivative is no longer effective in offsetting cash flows attributable to the hedged risk, the derivative expires or is sold, terminated, or exercised, the cash flow hedge is designated because a forecasted transaction is not probable of occurring, or management determines to remove the designation of the cash flow hedge. In all situations in which hedge accounting is discontinued and the derivative remains outstanding, the Company continues to carry the derivative at its fair value on the balance sheet and recognizes any subsequent changes in its fair value in in the Consolidated Statement of Comprehensive loss. When it is probable that a forecasted transaction will not occur, the Company discontinues hedge accounting and recognizes immediately in the Consolidated Statement of Comprehensive loss gains and losses that were accumulated in other comprehensive income related to the hedging relationship.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	(o) Share-based Payment The Company measures the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award and recognizes the costs over the period the employee is required to provide service in exchange for the award, which generally is the vesting period. The Company estimates grant date fair value using the Black Scholes-Merton option pricing model. The Company recognizes compensation cost for an award with only service conditions that has a graded vesting schedule on a straight-line basis over the requisite service period for the entire award, net of estimated forfeitures, provided that the cumulative amount of compensation cost recognized at any date at least equals the portion of the grant date value of such award that is vested at that date. Forfeiture rates are estimated based on historical and future expectations of employee turnover rates.
Revenue Recognition, Policy [Policy Text Block]	(p) Revenue Recognition Revenue is recognized when persuasive evidence of an arrangement exists, delivery of the product has occurred, the fee is fixed or determinable and collectability is reasonably assured. These criteria are determined in relation to the sale of the Company’s products or services as follows: For all sales, the Company requires a contract or purchase order which specified pricing, quantity and product specifications. For sales of PV modules from PRC to foreign customers, delivery of the products occurs at the point the product is delivered to the named port of shipment, which is when the risks and rewards of ownership are transferred to the customer. For sales of PV modules to domestic customers in PRC or by foreign subsidiaries, delivery of the product occurs at the point the product is received by the customer, which is when the risks and rewards of ownership have been transferred. Sales of PV systems consist of the delivery, assembly and installation of PV modules, related power electronics and other components. The Company considers the PV system to be delivered, and the risks and rewards of ownership transferred, when installation of all components is complete and customer acceptance is received. Customer acceptance is evidenced by a signed project acceptance document. The assembly and installation of PV systems is short, generally lasting between 1 3 The Company recognizes revenue for solar power station constructed for commercial customers according to ASC 605-35, Revenue Recognition—Construction-Type and Production Type Contracts 24,912 14,962 2,155 Starting in 2015, the Company provides PV cell / PV module processing services to customers. Under certain of these processing service arrangements, the Company purchases raw materials from a customer and agrees to sell a specified quantity of PV cells / PV modules produced from such materials back to the same customer. The Company recognizes revenue from these processing transactions on a net basis, that is, the revenue is recorded based on the amount received for PV cells / PV modules sold less the amount paid for the raw materials purchased from the customer. For revenue from electricity generation, the Company recognizes revenue when persuasive evidence of a power purchase arrangement with the power grid company exists, electricity has been generated and been transmitted to the grid and the electricity generation records are reconciled with the grid companies, the price of electricity is fixed or determinable and the collectability of the resulting receivable is reasonably assured. For sales of raw materials, PV cells and wafers, delivery occurs at the point the product is delivered to the customer, which is when the risks and rewards of ownership have been transferred. Delivery is evidenced by a signed customer acceptance form. S hipping and handling fees billed to customers are recorded as revenues, and the related shipping or delivery costs of RMB 311,356 239,519 148,959 21,454 Advance payments received from customers for future sale of inventory are recognized as advances from customers in the consolidated balance sheets. Advances from customers are recognized as revenues when the conditions for revenue recognition described above have been satisfied. Advances from customers have been recognized as a current liability because the amount at each balance sheet date is expected to be recognized as revenue within twelve months. In 2010 – 2012, a government subsidy project called “Golden Sun” program was proposed by the Ministry of Finance of PRC (“MOF”), to support and encourage PV stations installation. PV station owners could apply for a “Golden Sun” subsidy for the PV station to be constructed and solar companies may bid for the project as target vendors who would be authorized to supply PV modules to qualified PV station. According to detail implementation guidance, the government will give subsidy to each qualified PV station owners and the PV station owners’ obligation was to make sure that qualified PV stations would be successfully connected to national electric grid and pass the acceptance check by authorized supervisor appointed by the government (“government acceptance check”) within the period required by the government. Instead of paying full subsidy to PV station owners directly, the government should pay partial subsidy to qualified suppliers on behalf of PV station owners as advance before the commencement of construction of PV stations. Yingli China was a successful bidder as the qualified supplier for “Golden Sun” program. For year ended December 31, 2015, as agreed with local government of Hebei Province, due to that certain PV stations didn’t start construction and passed the government acceptance check within the required period, subsidy with RMB 286,277 286,277 41,232 The sales of the subsidiaries in the PRC are subject to Value added tax (“VAT”) at a general rate at 17

Standard Product Warranty, Policy [Policy Text Block]	(s) Warranty Cost Before September 30, 2011, the Company’s multicrystalline PV modules are typically sold with a two or five-year limited warranty for defects in materials and workmanship, and a 10 25 90 80 91.2 80.7 10 25 98.0 92.0 82.0 10 25 The Company performs industry-standard testing to test the quality, durability and safety of the Company’s products. As a result of such tests, management believes the quality, durability and safety of its products are within industry norms. Management’s estimate of the amount of its warranty obligation is based on the results of these tests, consideration given to the warranty accrual practice of other companies in the same industry and the Company’s expected failure rate and future costs to service failed products. The Company’s warranty obligation will be affected by its estimated product failure rates, the costs to repair or replace failed products and potential service and delivery costs incurred in correcting a product failure. Consequently, the Company accrues the equivalent of 1% of gross revenues as a warranty liability to accrue the estimated cost of its warranty obligations. To the extent that actual warranty costs differ significantly from estimates, the Company will revise its warranty provisions accordingly. Actual warranty costs are charged against the accrued warranty liability. Warranty expense is recorded as selling expense.

Purchase Commitment [Policy Text Block]	Firm Purchase Commitment The Company entered into several long-term fixed price contracts to purchase polysilicon to ensure an adequate supply of polysilicon to operate its plants. These contracts represent firm purchase commitments which are evaluated for potential market value losses. For the years ended December 31, 2014, 2015 and 2016, provision for reserve for inventory purchase commitments recognized was nil, RMB 77,705 90,300 13,006 522,050 10,672 1,537
Income Tax, Policy [Policy Text Block]	(u) Income Taxes Income taxes are accounted for under the asset and liability method. Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and any tax loss and tax credit carry forwards. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred income tax assets and liabilities of a change in tax rates or tax laws is recognized in the consolidated statements of comprehensive loss in the period the change in tax rates or tax laws is enacted. A valuation allowance is provided to reduce the amount of deferred income tax assets if it is considered more likely than not that some portion or all of the deferred income tax assets will not be realized. The Company recognizes in the consolidated financial statements the impact of an unrecognized tax benefit, if the position is not more likely than not of being sustained upon examination, based on the technical merits of the position. Recognized income tax benefits are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Company’s accounting policy is to accrue interest and penalties related to unrecognized tax benefits, if and when required, as interest expense and general and administrative expenses, respectively, in the consolidated statements of comprehensive loss.
Commitments and Contingencies, Policy [Policy Text Block]	(v) Commitments and Contingencies Liabilities for loss contingencies arising from claims, assessments, litigation, fines and penalties and other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. The Company is exposed to risks associated with liability claims in the event that the use of the PV products the Company sells results in injury. The Company does not maintain any third-party liability insurance coverage other than limited product liability insurance or any insurance coverage for business interruption. As a result, the Company may have to pay for financial and other losses, damages and liabilities, including, those in connection with or resulting from third-party product liability claims and those caused by natural disasters and other events beyond the Company’s control, out of its own funds, which could have a material adverse effect on its financial conditions and results of operations.
Segment Reporting, Policy [Policy Text Block]	(w) Segment Reporting The Company uses the management approach in determining reportable operating segments. The management approach considers the internal organization and reporting used by the Company’s chief operating decision maker for making operating decisions, allocating resources and assessing performance as the source for determining the Company’s reportable segments. Management has determined that the Company has only one operating segment.
Earnings Per Share, Policy [Policy Text Block]	Earnings Per Share In accordance with FASB ASC Topic 260, Earnings Per Share, basic earnings per share is computed by dividing net income attributable to ordinary shareholders by the weighted average number of ordinary shares outstanding during the year. Diluted earnings per share is calculated by dividing net income attributable to ordinary shareholders as adjusted for the effect of dilutive ordinary equivalent shares, if any, by the weighted average number of ordinary and dilutive ordinary equivalent shares outstanding during the year. Ordinary equivalent shares consist of the ordinary shares issuable upon the exercise of outstanding share options (using the treasury stock method). Potential dilutive securities are not included in the calculation of dilutive earnings per share if the impact is anti-dilutive.
Fair Value Measurement, Policy [Policy Text Block]	(y) Fair Value Measurements The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels: Level 1 Inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date. Level 2 Inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability. Level 3 Inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at measurement date. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to measurements involving significant unobservable inputs (Level 3 measurements). The level in the fair value hierarchy within which a fair value measurement in its entirety falls is based on the lowest level input that is significant to the fair value measurement in its entirety. See note (8) to the consolidated financial statements.
Reclassification Of Comparative Figures [Policy Text Block]	(z) Reclassification of comparative figures Certain comparative figures have been reclassified to conform to the current year presentation.
New Accounting Pronouncements, Policy [Policy Text Block]	(aa) Recently Issued Accounting Standards I n May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”). ASU 2014-09 supersedes the revenue recognition requirements in ASC Topic 605, Revenue Recognition, and most industry-specific guidance. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The new standard will require the Company to separate performance obligations within a contract, determine total transaction costs, and ultimately allocate the transaction costs across the established performance obligations. In August 2015, the FASB issued ASU No. 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. As a result, ASU 2014-09 will become effective for the Company beginning in fiscal 2018 under either full or modified retrospective adoption, with early adoption permitted as of the original effective date of ASU 2014-09. The Company has set up an implementation team that is currently in the process of analyzing each of the Company’s revenue streams in accordance with the new revenue standard to determine the impact on the Company’s consolidated financial statements. The Company plans to continue the evaluation, analysis, and documentation of its adoption of ASU 2014-09 (including those subsequently issued updates that clarify ASU 2014-09’s provisions) throughout 2017 as the Company works towards the implementation and finalizes its determination of the impact that the adoption will have on its consolidated financial statements. The Company expects to adopt the new revenue recognition guidance in the first quarter of 2018. In August 2014, the FASB issued ASU No. 2014-15, “Presentation of Financial Statements — Going Concern”. This standard requires management to evaluate for each annual and interim reporting period whether it is probable that the reporting entity will not be able to meet its obligations as they become due within one year after the date that the financial statements are issued. If the entity is in such a position, the standard provides for certain disclosures depending on whether or not the entity will be able to successfully mitigate its going concern status. This guidance is effective for annual periods ending after December 15, 2016 and interim periods within annual periods beginning after December 15, 2016. The Company adopted this standard during the fourth quarter of 2016 for related disclosure. In November 2015, the FASB issued ASU 2015-17, "Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes”. This ASU amends existing guidance to require that deferred income tax liabilities and assets be classified as noncurrent in a classified balance sheet, and eliminates the prior guidance which required an entity to separate deferred tax liabilities and assets into a current amount and a noncurrent amount in a classified balance sheet. The amendments in this ASU are effective for annual reporting periods beginning after December 15, 2016, and interim periods within those annual periods. Earlier application is permitted as of the beginning of an interim or annual period. Additionally, the new guidance may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. The Company plans to apply the new guidance retrospectively in 2017. The impact of adopting this guidance is not expected to be material to the consolidated financial statements given the Company’s deferred tax amounts. In January 2016, the FASB issued ASU 2016-01, “Financial Instruments (Topic 825): Recognition and Measurement of Financial Assets and Liabilities”. The amended guidance (i) requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income; (ii) eliminates the requirement to disclose the method(s) and significant assumptions used to estimate the fair value that is currently required to be disclosed for financial instruments measured at fair value; (iii) requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments and (iv) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements. ASU 2016-01 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, or calendar 2018 for the Company. The amended guidance should be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The impact of adopting this guidance is not expected to be material to the consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)”. Under the new guidance, lessees will be required to recognize a lease liability and a lease asset for all leases, including operating leases, with a term greater than 12 months on the balance sheet. The update also expands the required quantitative and qualitative disclosures surrounding leases. This update is effective for the Company from calendar 2019 and from the first interim period of calendar 2019, with earlier application permitted. The Company is evaluating the impact of the adoption of this update on its consolidated financial statements and related disclosures. In March 2016, the FASB issued ASU No. 2016-06, Contingent Put and Call Options in Debt Instruments. The amendments in this Update apply to all entities that are issuers of or investors in debt instruments (or hybrid financial instruments that are determined to have a debt host) with embedded call (put) options. The Amendments in this Update clarify the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts, which is one of the criteria for bifurcating an embedded derivative. An entity performing the assessment under the amendments in this Update is required to assess the embedded call (put) options solely in accordance with the four-step decision sequence. Consequently, when a call (put) option is contingently exercisable, an entity does not have to assess whether the event that triggers the ability to exercise a call (put) option is related to interest rates or credit risks. The amendments are an improvement to GAAP because they eliminate diversity in practice in assessing embedded contingent call (put) options in debt instruments. For public companies, the amendments in this Update are effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. An entity should apply the amendments in this Update on a modified retrospective basis to existing debt instruments as of the beginning of the fiscal year for which the amendments are effective. The Company is currently assessing the potential significant effects of these changes on the Company’s consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-07, Simplifying the Transition to the Equity Method of Accounting. The amendments in this Update eliminate the requirement that when an investment qualified for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor's previous held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. The amendments in this Update require that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. The amendments in this Update are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The amendments should be applied prospectively upon their effective date to increase in the level of ownership interest or degree of influence that result in the adoption of the equity method. Earlier application is permitted. The Company is currently assessing the potential significant effects of these changes on the Company’s consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, “Compensation — Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting,” which outlines new provisions intended to simplify various aspects related to accounting for share-based payments and their presentation in the financial statements. The Company currently plans to implement this ASU as required in the first quarter of calendar 2017. The Company does not expect that the adoption will have a material impact on its consolidated financial statements. I n June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” This ASU requires a financial asset (or group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset(s) to present the net carrying value at the amount expected to be collected on the financial asset. The standard is effective for the Company from calendar 2020, with early adoption permitted for calendar 2019. The Company has yet to commence an evaluation of the impact of the adoption of this standard on its consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, “Classification of Certain Cash Receipts and Cash Payments (Topic 230)." Current GAAP is unclear or does not include specific guidance on how to classify certain transactions in the statement of cash flows. This ASU is intended to reduce diversity in practice in how eight particular transactions are classified in the statement of cash flows. ASU No. 2016-15 is effective for interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted, provided that all of the amendments are adopted in the same period. Entities will be required to apply the guidance retrospectively. If it is impracticable to apply the guidance retrospectively for an issue, the amendments related to that issue would be applied prospectively. The Company is currently assessing the potential significant effects of these changes on the Company’s consolidated financial statemen ts

[1]	In September 2009, Yingli China and two other entities, unrelated to the Company, established Hainan Tianneng Power Co., Ltd. (“Hainan Tianneng”). Yingli China contributed RMB 6,000 to acquire a 20% equity interest. In 2011, Yingli China further injected cash of RMB 20,362 while the other investors made proportional cash injection to remain the same ownership interest for each investor. In 2012, the other investors made further capital injection to Hainan Tianneng, which resulted in a decrease of equity interest held by Yingli China to 11.45% as of December 31, 2012. In June and July 2013, Hainan Yingli made capital injections in the amount of RMB 40 million and RMB 12 million respectively, to acquire 18.31% equity interest of Hainan Tianneng in total. Together with the equity interest held by Yingli China (9.35%), the Company (including both Yingli China and Hainan Yingli) holds 27.66% equity interest in Hainan Tianneng as of December 31, 2013 and 2014. In May 2015, one of the other investors made further capital injection to Hainan Tianneng, which resulted in a decrease of equity interest held by the Company to 26.53% as of December 31, 2015. The investment is accounted for under equity method. In December 2016, as discussed in note 15(b), Yingli China and Hainan Yingli transferred all of the equity interest in Hainan Tianneng to the other investor. The total consideration was RMB 95,840 (US$ 13,804) and a gain of RMB 34,295 (US$ 4,940) was recognized in “Other Income” in the Consolidated statement of Comprehensive Loss for year ended December 31, 2016.
[2]	In August 2014, Yingli China and Shanghai Sailing Capital Management Co., Ltd. (“Shanghai Sailing”), unrelated to the Company, set up a fund called Shanghai Sailing Xili Equity Investment Fund LLP (“Sailing Fund”). The capital size of Sailing Fund is of RMB 1,004,000 and its principal activities are to make equity investments to new energy industries. According to the agreement, Sailing Fund is jointly controlled by Shanghai Sailing and Yingli China with shares of interest of 49.2% and 50.8%, respectively. As of December 31, 2015, total capital injected by Yingli China is RMB 153,000 (US$ 23,619) while Shanghai Sailing also made cash injection proportionally based on the agreed percentage of shares of interest between the parties in Sailing Fund. Therefore, the investment is accounted for under equity method. In March 2016, all partners of Sailing Fund decided to liquidate Sailing Fund. Due to the liquidation has not completed, as of December 31, 2016, the investment was still recorded as long term investment, and the Company recorded an impairment provision of RMB 17,251(US$ 2,485) for this equity investment for the difference between the carry value of the long term investment and the fair value of the liquidation amount expected to be received.
[3]	In August 2014, Yingli China together with two other entities unrelated to the Company, established Tongmei Yingli New Energy Industry Co., Ltd. Yingli China contributed RMB 30,000 to acquire a 30% equity interest. The investment is accounted for under equity method.
[4]	In June 2015, Yingli Beijing and two other entities, unrelated to the Company, established Shandong Hi-speed Yingli New Energy Co., Ltd. (“Shandong Hi-speed Yingli”). Yingli Beijing has contributed RMB 17,500 to acquire a 35% equity interest. The investment is accounted for under equity method.
[5]	In July 2013, Yingli Japan, together with two other entities unrelated to the Company, established Solariant Portfolio Two Godo Kaisha (the project“SPC”) to acquire 49.48% equity interest. Yingli Japan made capital contribution of JPY 151,500 (RMB 7,782 equivalent) in 2014. Pursuant to an agreement entered into by all parties in early 2015, SPC transferred SPC’s payables of JPY 395,000 (RMB 20,580 equivalent, US$ 3,177) to Yingli Japan, which was treated as a capital injection, meanwhile, the other two investors also made capital injection to SPC. After the transaction was made, total investment by Yingli Japan was amounted to JPY 546,500 and equity interest owned by Yingli Japan decreased to 37.5%. In July 2015, Yingli Japan together with other two investors of SPC, entered into several agreement to transfer 100% of equity interest of SPC to another entity unrelated to the Company. As of December 31, 2015, due to that the share transfer has not completed, partial consideration of JPY 815,700 (RMB 42,499 equivalent) received was recorded in “Other current liabilities and accrued expenses” in Consolidated Balance Sheets. In 2016, the transaction had been completed and according to the final equity transferring contract, the consideration would be paid through five installment(with the fifth being contingent, as discussed below) and as of December 31, 2016, Yingli Japan had received the first four installment of total JPY 1,565,500 (RMB 89,197 equivalent), and a disposal gain of JPY 1,052,422 (RMB 62,830 equivalent), which was the difference between the carry value of the long term investment at the disposal date and the JPY 1,565,500 ( RMB 89,197 equivalent), was recognized in “Other Income” in the Consolidated Statements of Comprehensive Loss. The gain was mainly resulted from the unrecognized assets related to the entitlement granted to Solariant for the construction of the project assets. Since the fifth installment of JPY261,800 is contingent and won’t be paid to Yingli Japan until the project asset owned by the SPC is connected to the grid, no receivables and gain of the fifth installment was recognized in 2016.
[6]	In February 2010, Yingli China and two other entities, unrelated to the Company, established Beijing Jingyi Green Energy Power System Engineering Co., Ltd. Yingli China contributed RMB 10,000 to acquire a 10% equity interest. In July 2011, Yingli China injected cash of RMB 1,875 while the other investors made proportional cash injection to remain the same ownership interest for each investor. The investment is accounted for under cost method.

The Investment Company’s period of operation is 10 years and its principal activities are to make equity investments to key industries encouraged by the State.

[1]	In September 2009, Yingli China and two other entities, unrelated to the Company, established Hainan Tianneng Power Co., Ltd. (“Hainan Tianneng”). Yingli China contributed RMB 6,000 to acquire a 20% equity interest. In 2011, Yingli China further injected cash of RMB 20,362 while the other investors made proportional cash injection to remain the same ownership interest for each investor. In 2012, the other investors made further capital injection to Hainan Tianneng, which resulted in a decrease of equity interest held by Yingli China to 11.45% as of December 31, 2012. In June and July 2013, Hainan Yingli made capital injections in the amount of RMB 40 million and RMB 12 million respectively, to acquire 18.31% equity interest of Hainan Tianneng in total. Together with the equity interest held by Yingli China (9.35%), the Company (including both Yingli China and Hainan Yingli) holds 27.66% equity interest in Hainan Tianneng as of December 31, 2013 and 2014. In May 2015, one of the other investors made further capital injection to Hainan Tianneng, which resulted in a decrease of equity interest held by the Company to 26.53% as of December 31, 2015. The investment is accounted for under equity method. In December 2016, as discussed in note 15(b), Yingli China and Hainan Yingli transferred all of the equity interest in Hainan Tianneng to the other investor. The total consideration was RMB 95,840 (US$ 13,804) and a gain of RMB 34,295 (US$ 4,940) was recognized in “Other Income” in the Consolidated statement of Comprehensive Loss for year ended December 31, 2016.
[2]	In September 2011, Yingli Beijing and a subsidiary of Yingli Group, established Yingli Shuntong (Beijing) International Freight Agency Co., Ltd (“Shuntong Wuliu”). Yingli Beijing contributed RMB 1,470 to acquire 49% equity interest. As of December 31, 2013, the investment is accounted for under equity method. In December 2014, Yingli Beijing disposed all its equity interest in Shuntong Wuliu to Tianjin Yingli Bubalus Logistics Co., Ltd., a related party of the Company. The total consideration was RMB 1,941 and no gain or loss arose from this transaction.
[3]	In August 2014, Yingli China and Shanghai Sailing Capital Management Co., Ltd. (“Shanghai Sailing”), unrelated to the Company, set up a fund called Shanghai Sailing Xili Equity Investment Fund LLP (“Sailing Fund”). The capital size of Sailing Fund is of RMB 1,004,000 and its principal activities are to make equity investments to new energy industries. According to the agreement, Sailing Fund is jointly controlled by Shanghai Sailing and Yingli China with shares of interest of 49.2% and 50.8%, respectively. As of December 31, 2015, total capital injected by Yingli China is RMB 153,000 (US$ 23,619) while Shanghai Sailing also made cash injection proportionally based on the agreed percentage of shares of interest between the parties in Sailing Fund. Therefore, the investment is accounted for under equity method. In March 2016, all partners of Sailing Fund decided to liquidate Sailing Fund. Due to the liquidation has not completed, as of December 31, 2016, the investment was still recorded as long term investment, and the Company recorded an impairment provision of RMB 17,251(US$ 2,485) for this equity investment for the difference between the carry value of the long term investment and the fair value of the liquidation amount expected to be received.
[4]	In August 2014, Yingli China together with two other entities unrelated to the Company, established Tongmei Yingli New Energy Industry Co., Ltd. Yingli China contributed RMB 30,000 to acquire a 30% equity interest. The investment is accounted for under equity method.
[5]	In June 2015, Yingli Beijing and two other entities, unrelated to the Company, established Shandong Hi-speed Yingli New Energy Co., Ltd. (“Shandong Hi-speed Yingli”). Yingli Beijing has contributed RMB 17,500 to acquire a 35% equity interest. The investment is accounted for under equity method.
[6]	In July 2013, Yingli Japan, together with two other entities unrelated to the Company, established Solariant Portfolio Two Godo Kaisha (the project“SPC”) to acquire 49.48% equity interest. Yingli Japan made capital contribution of JPY 151,500 (RMB 7,782 equivalent) in 2014. Pursuant to an agreement entered into by all parties in early 2015, SPC transferred SPC’s payables of JPY 395,000 (RMB 20,580 equivalent, US$ 3,177) to Yingli Japan, which was treated as a capital injection, meanwhile, the other two investors also made capital injection to SPC. After the transaction was made, total investment by Yingli Japan was amounted to JPY 546,500 and equity interest owned by Yingli Japan decreased to 37.5%. In July 2015, Yingli Japan together with other two investors of SPC, entered into several agreement to transfer 100% of equity interest of SPC to another entity unrelated to the Company. As of December 31, 2015, due to that the share transfer has not completed, partial consideration of JPY 815,700 (RMB 42,499 equivalent) received was recorded in “Other current liabilities and accrued expenses” in Consolidated Balance Sheets. In 2016, the transaction had been completed and according to the final equity transferring contract, the consideration would be paid through five installment(with the fifth being contingent, as discussed below) and as of December 31, 2016, Yingli Japan had received the first four installment of total JPY 1,565,500 (RMB 89,197 equivalent), and a disposal gain of JPY 1,052,422 (RMB 62,830 equivalent), which was the difference between the carry value of the long term investment at the disposal date and the JPY 1,565,500 ( RMB 89,197 equivalent), was recognized in “Other Income” in the Consolidated Statements of Comprehensive Loss. The gain was mainly resulted from the unrecognized assets related to the entitlement granted to Solariant for the construction of the project assets. Since the fifth installment of JPY261,800 is contingent and won’t be paid to Yingli Japan until the project asset owned by the SPC is connected to the grid, no receivables and gain of the fifth installment was recognized in 2016.
[7]	In February 2010, Yingli China and two other entities, unrelated to the Company, established Beijing Jingyi Green Energy Power System Engineering Co., Ltd.

[1]	Prior to FY 2014, Baoding Tianwei Baobian Electric Co., Ltd. (“Tianwei Baobian”), a third party, held 25.99% equity interest in Tianwei Yingli. In May 2014, the Company, Baoding Tianwei Group Co., Ltd.(“ Tianwei Group”, another third party unrelated to the Company), and Tianwei Baobian entered into a new joint venture contract and Tianwei Baobian transferred 7% equity interest in Tianwei Yingli to Tianwei Group. Under a Sino-foreign equity joint venture company contract with Tianwei Baobian and Tianwei Group, it provides that Tianwei Baobian and/or Tianwei Group will have a right to swap the shares of the Company with the all but not part shares of the non-controlling interest in Tianwei Yingli. The terms of the swap will be discussed separately at the time of the swap. The Company does not account for such share swap until a separate agreement is signed that clearly states the terms and basis of the share swap between the non-controlling shareholders and the Company. Tianwei Baobian and/or Tianwei Group may exercise this subscription right after certain conditions are satisfied following the completion of the Company’s IPO. Tianwei Baobian and/or Tianwei Group’s subscription rights to subscribe for newly issued ordinary shares of the Company in exchange for all but not part of Tianwei Baobian and/or Tianwei Group’s equity interest in Tianwei Yingli did not have an effect on earnings per share as these rights are contingent upon Tianwei Baobian and/or Tianwei Group obtaining all necessary approvals from relevant PRC government authorities for acquiring our ordinary shares in the future. As of December 31, 2016, Tianwei Baobian and/or Tianwei Group haven’t exercised this subscription right. Subject to applicable laws in the PRC, the Cayman Islands, any jurisdiction in which our ordinary shares are listed and any jurisdiction in which a qualified securities exchange, including the NYSE, is located and further subject to the listing rules of such exchange, Tianwei Baobian and/or Tianwei Group may exercise the subscription right by sending a written notice to us within one month following the first date on which all conditions listed above are satisfied, accompanied by copies of related approvals and opinion of counsel. Prior to exercising its subscription right, Tianwei Baobian and/or Tianwei Group is required to retain an asset valuation firm reasonably acceptable to us to obtain a valuation of Tianwei Baobian and/or Tianwei Group’s equity interest in Tianwei Yingli in accordance with internationally accepted valuation methods and relevant PRC laws and regulations. The valuation report will need to be acknowledged by both Tianwei Baobian and/or Tianwei Group and us. The number of our new ordinary shares that the Company is obligated to issue to Tianwei Baobian and/or Tianwei Group upon its exercise of the subscription right will be calculated. Number of new shares to be issued to Tianwei Baobian and/or Tianwei Group = Total number of our shares immediately before the exercise of the subscription right *(Percentage of Tianwei Baobian and/or Tianwei Group’s equity interest in Tianwei Yingli immediately before the exercise of the subscription right/ Percentage of our equity interest in Tianwei Yingli immediately before the exercise of the subscription right)
[2]	In December 2016, the Company entered into an agreement with the non-controlling interest holder of Hainan Yingli (“Hainan NCI”) to acquire the remaining 4.25% equity interest of Hainan Yingli, the consideration was RMB138.4 million, which was based on the fair value of Hainan Yingli. As a result, Hainan Yingli became a wholly owned subsidiary of the Company. The difference between the consideration of RMB 138.4 million and the carry value of Non-controlling interest of Hainan at the transaction date of RMB 60.5 million, was recorded in Accumulated deficits for the year ended December 31, 2016. Contemporaneously, Yingli China together with Hainan Yingli signed an agreement with Hainan NCI to dispose all of their equity interest of 26.53% in Hainan Tianneng to Hainan NCI, the consideration was RMB95.8 million.
