	(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.
	For the year ended December 31, 2013, the Company incurred a net loss of RMB 2,054,898 (US$ 339,444). As of December 31, 2013, the Company had cash, cash equivalents and restricted cash of RMB 2,797,808 (US$ 462,165) and short-term bank borrowings, including current portion of long-term bank borrowings of RMB 6,715,877 (US$ 1,109,384). The liquidity of the Company is primarily depending on its ability to maintain adequate cash flows from operations, to renew its short-term bank loans and to obtain adequate external financing 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 ending December 31, 2014. Based on such forecast, management believes that adequate sources of liquidity exist to fund the Company’s working capital and capital expenditures requirements, and to meet its short term debt obligations and other liabilities and commitments as they become due. In preparing the cash flow forecast, management has considered historical cash requirements of the Company, as well as other key factors, including its ability to renew its short-term bank borrowings during 2014. If available liquidity is not sufficient to meet the Company’s operating and debt service obligations as they become due, management’s plans include pursuing alternative financing arrangements or reducing expenditures as necessary to meet the Company’s cash requirements throughout 2014.  However, there is no assurance that, if required, the Company will be able to raise additional capital or reduce discretionary spending to provide the required liquidity.
	(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 equity interest not held by the Company is presented as noncontrolling interests. All significant inter-company balances and transactions have been eliminated upon consolidation.
	(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 100%, 91% and 90% of its total net revenues for the years ended December 31, 2011, 2012 and 2013, respectively, from sales to customers in countries with known government incentive programs for the use of solar products. A significant reduction in the scope or discontinuation of government incentive programs would have a materially adverse effect on the demand of the Company’s products.
	A significant portion of the Company’s net revenues are from customers located in Germany, the United States of America (“USA”) and PRC.  Revenues from customers located in Germany, USA and PRC are as follows:
		Year ended
		December 31,	% of net		December 31,		% of net		December 31, 2013		% of net
		2011	revenue		2012		revenue				revenue
		RMB			RMB				RMB	US$
	Germany	6,595,109	45	%	4,765,312		42	%	2,439,058	402,904	18	%
	USA	2,137,219	15	%	1,600,695		14	%	2,906,262	480,080	22	%
	PRC	3,261,886	22	%	2,653,341		23	%	4,546,482	751,025	34	%
	Total	11,994,214	82	%	9,019,348		79	%	9,891,802	1,634,009	74	%
	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 2011, 2012 and 2013, sales to the top five customers accounted for approximately 27.7%, 26.0% and 15.2%, respectively, of the Company’s net revenues.
	As of December 31, 2012 and 2013, the top five outstanding accounts receivable balance (net of provisions) accounted for approximately 24.2% and 20.1%, respectively, of the Company’s total outstanding accounts receivable.
	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 1,703,312 and RMB 1,682,521 (US$ 277,933) as of December 31, 2012 and 2013, respectively.  The Company makes the prepayments without receiving collateral for such payments.  As a result, the Company’s claims for such prepayments would rank only as an unsecured claim, which exposes the Company to the credit risks of the suppliers. As of December 31, 2012 and 2013, advances made to individual suppliers in excess of 10% of total prepayments to suppliers are as follows:
			December 31,
			2012		2013
		Location	RMB		RMB		US$
	Supplier A	Singapore	184,523		210,343		34,746
	Supplier B	South Korea	230,108		158,040		26,106
	Supplier C	Germany	958,284		900,821		148,805
	Total		1,372,915		1,269,204		209,657
	The Company obtains some equipment 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 229,181 and RMB 122,340 (US$ 20,209) as of December 31, 2012 and 2013, respectively, for the purchase of equipment without receiving collateral for such payments.  As a result, the Company’s claims for such payments would rank only as an unsecured claim, which exposes the Company to the credit risks of the equipment suppliers.

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, 2012 and 2013, the Company had cash balances at three PRC individual financial institutions that held cash balances in excess of 10% of the Company’s total cash balances. These bank deposits collectively accounted for approximately 42.4% and 41.7% of the Company’s total cash balances as of December 31, 2012 and 2013, respectively.  Management believes that these financial institutions are of high credit quality.
(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, goodwill and intangible assets, the fair value of share-based payments, the collectibility 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 assumptions.
(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 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 fully 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 2013 RMB amounts have been translated into U.S. dollar amounts at the rate of RMB 6.0537 to S$1.00, the noon buying rate in the City of New York for cable transfers of RMB per U.S. dollar as set forth in the H.10 weekly statistical release of the Federal Reserve Board, as of December 31, 2013. No representation is made that RMB amounts could have been, or could be, converted into U.S. dollars at that rate or at any other certain rate on December 31, 2013, or at any other date.
(f)                          Cash, Cash equivalents and Restricted Cash
Cash and cash equivalents consist of cash on hand, cash in bank accounts, and interest bearing savings accounts with an initial term of three months or less.
Restricted cash of RMB 966,878 and RMB 1,692,330 (US$ 279,553) as of December 31, 2012 and 2013, respectively, represents bank deposits for securing letters of credit and letters of guarantee granted to the Company, primarily for the purchase of inventory and equipment and the guarantee of the offshore bank borrowings. Such letters of credit and letters of guarantee expire within one year. The cash flows from bank deposits as the guarantee of the offshore bank borrowings are reported within cash flows for financing activities in the consolidated statements of cash flows.  The cash flows from the bank deposits relating to purchases of inventory and equipment are reported within cash flows from operating activities and investing activities in the consolidated statements of cash flows, respectively.
(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 2012 and 2013, the Company entered into agreements to sell without recourse certain accounts receivable to several PRC banks. The buyer is 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 has 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 223,273 and RMB 677,795 (US$ 111,964) for the years ended December 31, 2012 and 2013, respectively, and has included the proceeds in net cash provided by operating activities in the consolidated statements of cash flows. The Company recorded a loss on the sale of accounts receivable of RMB 2,100 and RMB 11,840 (US$ 1,956) for the years ended December 31, 2012 and 2013, respectively, which is included in general and administrative expense.
(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.
(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 balance of the “prepayments to suppliers” is reduced and reclassified to ‘‘inventories’’ when inventory is received and passes quality inspection. Such reclassifications of RMB 476,113, RMB 495,679 and RMB 245,906 (US$40,621) for the years ended December 31, 2011, 2012 and 2013, respectively, are not reflected as cash outflows from operating activities.  In addition, the Company agreed with one of its polysilicon suppliers, pursuant to which the Company offset the balance of prepayment to the supplier against the balance of accounts payable in the amount of US$23,338 (RMB141,281) during 2013.  As of December 31, 2012 and 2013, prepayments to suppliers of RMB 1,280,131 and RMB 884,562 (US$ 146,119), respectively, representing the portion expected to be utilized after twelve months have been classified as “long-term prepayments to suppliers” in the consolidated balance sheets and relate to prepayments to suppliers for long-term supply agreements with deliveries scheduled to commence beyond the next twelve months at each respective balance sheet date.
(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.  The estimated useful lives of property, plant and equipment are as follows:
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.
Project assets
Project assets consist primarily of costs relating to solar power projects in various stages of development that are capitalized prior to the sale of the solar power project.  These costs include modules, installation and other development costs.  While the project assets are not constructed for a specific customer, the Company intends to sell the project assets upon their completion.  As of December 31, 2012 and 2013, RMB63 million and RMB 356 million (US$ 59 million) of project assets were included in the construction in progress
Goodwill and Other Intangible Assets
Goodwill is an asset representing the future economic benefits arising from other assets acquired in a business combination that are not individually identified and separately recognized. Goodwill and trademarks, which 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. The Company’s amortizable intangible assets consist of technical know-how, customer relationships, order backlog and short-term supplier agreements with the following estimated useful lives:
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. See note (5) to the consolidated financial statements.
Goodwill and intangible assets that are not subject to amortization are tested annually for impairment, 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 goodwill, the impairment test is a two step test. Under the first step, the fair value of the reporting unit is compared with its carrying value (including goodwill). If the fair value of the reporting unit is less than its carrying value, an indication of goodwill impairment exists for the reporting unit and the entity must perform step two of the impairment test (measurement). Under step two, an impairment loss is recognized for any excess of the carrying amount of the reporting unit’s goodwill over the implied fair value of that goodwill. The implied fair value of goodwill is determined by allocating the fair value of the reporting unit in a manner similar to a purchase price allocation and the residual fair value after this allocation is the implied fair value of the reporting unit goodwill. If the fair value of the reporting unit exceeds its carrying value, step two does not need to be performed.
The Company performs its annual impairment review of goodwill at December 31, and when a triggering event occurs between annual impairment tests. At December 31, 2011, the Company recognized a full impairment loss of RMB 273,382 on the goodwill. See note (22) to the consolidated financial statements.
Government grant
Government grants are recognized in the balance sheet initially when there is reasonable assurance that they will be received and that the Company will comply with the conditions attaching to them.
For the year ended December 31, 2011, the Company received government grants of RMB 125,599 related to the construction of the solar power plants and the procurement of machineries, which were recognized as long-term other liabilities.
For the year ended December 31, 2012, the Company received government grants of RMB 213,976 related to the construction of the solar power plants and the procurement of machineries, which were recognized as long-term other liabilities.
For the year ended December 31, 2013, the Company received government grants of RMB 350,028 (US$ 57,821) related to the construction of the solar power plants and the procurement of machineries, which were recognized as long-term other liabilities.
These grants are amortized as the related assets are depreciated or amortized. The grants amortized amounted to RMB9,484, RMB 13,130 and RMB 53,419 (US$ 8,824) for the year ended December 31, 2011, 2012 and 2013, respectively.
(k)                       Land Use Rights
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 years.
(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 investee, are accounted for using the equity method of accounting. Under the equity method of accounting, the Company’s share of the investee’s results of operations is included in other income (expense) in the Company’s consolidated statements of comprehensive loss. Equity investments are accounted for under the 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 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 2011, the Company recognized an impairment loss of RMB 8,720 on its equity investment. See note (8) to the consolidated financial statements.
(m)                    Statutory Reserves
In accordance with the relevant laws and regulations of the PRC, PRC enterprises are required to transfer 10% of their after tax profit, as determined in accordance with PRC accounting standard and regulations to a general reserve fund until the balance of the fund reaches 50% of the registered capital of the enterprise. The transfer to this general reserve fund must be made before distribution of dividends can be made.  As of December 31, 2012 and 2013, the PRC subsidiaries of the Company had appropriated RMB 461,623 and RMB 484,077 (US$ 79,964), respectively, to the general reserve fund, which is restricted from being distributed to the Company, and if applicable, to the noncontrolling interests.
(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 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 20 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 earnings. When it is probable that a forecasted transaction will not occur, the Company discontinues hedge accounting and recognizes immediately in earnings gains and losses that were accumulated in other comprehensive income related to the hedging relationship.
(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.  The Company applies the fair value method for equity instrument issued to non-employee under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 505-50, Equity-based Payments to Non-employees (“ASC Topic 505-50”).
(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 collectibility is reasonably assured.  These criteria as they relate to the sale of the Company’s products or services are as follows:
For all sales, the Company requires a contract or purchase order which quantifies pricing, quantity and product specifications.
For sales of PV modules from PRC to foreign customers, delivery of the products occurs at the point in time 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 in time 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 to 3 months, and requires advance payments from the customer.
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.  Revenue is recognized on a percentage-of-completion basis, based on the ratio of total costs incurred to date to total projected costs.  Provisions are made for the full amount of any anticipated losses on a contract-by-contract basis.  The Company recognized nil loss for these types of contracts for the year ended December 31, 2013.  Costs in excess of billings are recorded where costs recognized are in excess of amounts billed to customers of purchased commercial solar power stations. Costs in excess of billings as of December 31, 2013 amounted to RMB 216,759 (US$35,806), and are included in accounts receivable in the consolidated balance sheets.
Other revenue consists primarily of the sale of raw materials. Delivery for the sale of raw materials occurs at the point in time the product is delivered to the customer, which is when the risks and rewards of ownership have been transferred. Delivery is evidenced by a signed customer acceptance form.
Shipping and handling fees billed to customers are recorded as revenues, and the related shipping or delivery costs of RMB290,746, RMB 320,727 and RMB 405,839 (US$ 67,040) are recorded as selling expenses for the years ended December 31, 2011, 2012 and 2013, respectively.
Advance payments received from customers for the 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 the PRC, value added tax (“VAT”) at a general rate of 17% on invoice amount is collected on behalf of tax authorities in respect of the sales of product and services and is not recorded as revenue.  VAT collected from customers, net of VAT paid for purchases, is recorded as a liability until it is paid to the tax authorities.
(q)                      Research and Development
Research and development costs are expensed as incurred. Its research and development costs consist primarily of compensation and related costs for personnel, material, supplies, equipment depreciation and laboratory testing costs.
(r)                        Employee Benefits Plans
Pursuant to the relevant PRC regulations, the Company is required to make contributions for each PRC employee at a rate of 20% on a standard salary base as determined by the local Social Security Bureau, to a defined contribution retirement program organized by the local Social Security Bureau. In addition, the Company is also required to make contributions for each PRC employee at rates of 7.5%-10%, 1%-2%, 10%-12% and 1.2%-1.6% of standard salary base for medical insurance benefits, unemployment, housing fund and other statutory benefits, respectively.  Total amount of contributions for the years ended December 31, 2011, 2012 and 2013 was RMB 177,714, RMB 244,108 and 266,134 (US$ 43,962), respectively.
(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-year and 25-year warranty guaranteeing 90% and 80% of initial power generation capacity, respectively. With effect from October 1, 2011, the Company implemented a new and improved warranty terms for multicrystalline PV module that guarantees 91.2% and 80.7% of initial power generation capacity for 10 years and 25 years, respectively.  Further, in respect of monocrystalline Panda PV module, the Company guarantees 98.0%, 92.0% and 82.0% of initial power generation for the first year, 10 years and 25 years, respectively. In addition, based on customers’ specific requirements, the Company provides the multicrystalline PV modules with linear-based warranty which guarantees each year’s power output during the twenty-five-year warranty period. The Company bears the risk of warranty claims long after the Company has sold its products and recognized revenues. The Company has sold PV modules since January 2003, and none of the Company’s PV modules has been in use for the entire warranty periods. In connection with the Company’s PV system sales in the PRC, the Company provides a one- to five- year warranty against defects in the Company’s modules, storage batteries, controllers and inverters.
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.
Changes in the carrying amount of accrued warranty liability are as follows:
	Year Ended December 31,
	2011	2012		2013
	RMB	RMB		RMB		US$
Beginning balance	303,641	457,733		555,357		91,738
Warranty expense for the current year	154,092	109,915		125,900		20,797
Warranty costs incurred or claimed	—	(12,291	)	(14,311	)	(2,364	)
Total accrued warranty cost	457,733	555,357		666,946		110,171
Less: accrued warranty cost, current portion	32,383	35,819		40,632		6,712
Accrued warranty cost, excluding current portion	425,350	519,538		626,314		103,459
(t)                          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. The Company recognized a provision for inventory purchase commitments of RMB 851,694 in 2011 and RMB 480,182 (US$ 79,320) in 2013. See note (16) to the consolidated financial statements.
(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.
(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.
(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, as that term is defined by FASB ASC Topic 280, Segment reporting.
(x)                       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.
(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 (7) to the consolidated financial statements.
(z)                         Recently Issued Accounting Standards
In February 2013, the FASB issued ASU 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income (“ASU 2013-02”). The standard requires that companies present either in a single note or parenthetically on the face of the financial statements, the effect of significant amounts reclassified from each component of accumulated other comprehensive income based on its source (e.g., the release due to cash flow hedges from interest rate contracts) and the income statement line items affected by the reclassification (e.g., interest income or interest expense). If a component is not required to be reclassified to net income in its entirety (e.g., the net periodic pension cost), companies would instead cross reference to the related footnote for additional information (e.g., the pension footnote). ASU 2013-02 is effective for interim and annual reporting periods beginning after December 15, 2012. The Company adopted the new standard on January 1, 2013. The adoption did not have a material impact on its consolidated financial statements or related disclosures.
In July 2013, the FASB issued ASU 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.  ASU 2013-11 requires an unrecognized tax benefit, or a portion of an unrecognized tax benefit, to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward.  ASU 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2014.  The new standard is to be applied prospectively but retrospective application is permitted.  The adoption is not expected to have a material impact on the Company’s consolidated financial statements and related disclosures.

Derivative Instruments and Hedging Activities	'
	(6)                       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. (“Yingli Hainan”) and Yingli Energy (China) Co., Ltd. (“Yingli China”) are located in the PRC with the Renminbi being its functional currency. 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 USS$ 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, 2012, the Company entered into foreign currency forward contracts with a notional amount of EURO 39,000 and US$ 21,000 against its EURO and US$ denominated sales, respectively. During the year ended December 31, 2013, the Company entered into foreign currency forward contracts with a notional amount of EURO 100,690 and US$ 7,000 against its EURO and US$ denominated sales, respectively. As of December 31, 2012 and 2013, the Company had outstanding foreign currency forward contracts with notional amounts of US$ 18,000 and EURO 45,690, respectively.
	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 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, in 2009. As of December 31, 2012 and 2013, the Company had outstanding interest rate swap contracts with notional amounts of US$36,000 and US$ 27,000, respectively.

	(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.
·                       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 of comparable terms. The carrying value of the long-term debt and long-term payable approximate their fair values as the long-term debts and long-term payable carry variable interest rates which approximate rates currently offered by the Company’s bankers for similar debt instruments of comparable maturities.
·                      Medium-term notes — fair value is based on the amount of future cash flows associated with the debt instrument discounted at the Company’s current borrowing rate for similar debt instruments of comparable terms. As of December 31, 2012 and 2013, the carrying value of the medium-term notes approximate its fair value as the current incremental borrowing rate for similar types of borrowing arrangements did not differ significantly from the borrowing rate carried by the medium-term notes.
·                      Foreign currency forward contract — as of December 31, 2012 and 2013, the fair value is determined by discounting estimated future cash flow, which is based on the changes in the forward rate.
·                      Interests swap contract — as of December 31, 2012 and 2013 the fair value is determined by using pricing models developed based on the London Interbank Offered Rate (“LIBOR”) swap rate and other unobservable market data.

	In 2009, the Company entered into a note purchase agreement with Trustbridge Partners II, L.P. (“Trustbridge”), for up to US$50,000 in senior secured convertible notes (“Notes”). A first tranche of US$20,000 (RMB 136,564) Notes was issued in connection with the financing of the Cyber Power acquisition on January 16, 2009 (“First Tranche”). Additional Notes, which are referred to as the “Second Tranche”, for an aggregate principal amount of US$29,449 (RMB 201,084) was issued on July 2, 2009.
	The Notes carry an interest rate of 10% per annum which is paid on a quarterly basis and were convertible into the Company’s ordinary shares at an initial conversion rate of 17,699 ordinary shares per US$100 principal amount of Notes (equivalent to a conversion price of approximately US$5.65 per ADS), subject to certain adjustments.  At issuance, each of the Second Tranche Notes will initially be convertible at the conversion rate applicable to the outstanding First Tranche Notes. Unless previously redeemed, repurchased or converted, the Notes mature on January 25, 2012 at a redemption price equal to 152% of the principal amount which guaranteed a rate of return of 15% per annum in addition to the stated coupon rate of 10% per annum aforementioned.
	The holders of the Notes have the right, at any time prior to the maturity date of the Notes, to convert the principal amount of the Note plus any accrued but unpaid interest, into shares of the Company.
	In addition to the standard dilution protection adjustments, the conversion rate shall be adjusted under the following conditions:
	(i)                           If the Company issues shares at a price less than the ten day average share price, the conversion rate shall be increased such that the conversion price is equal to such issuance price. No adjustment is made to decrease the conversion rate;
	(ii)                        The conversion rate shall be increased such that the conversion price is equal to the average daily volume-weighted average share price (“VWAP”) (20 day forward looking) as of each of the following dates: (a) the date the Company releases its earnings results for fiscal year 2008; (b) the date the Company releases its earnings results for the second fiscal quarter 2009, and (c) the date the Company releases its earnings results for fiscal year 2009.  No adjustment is made to decrease the conversion rate. On February 10, 2009, the Company released its earnings results for fiscal year 2008 and the conversion rate was increased to 22,933 per US$100 (approximately US$4.36 per ADS); and
	(iii)                     On March 31, June 30, September 30 and December 31 of each year, commencing on June 30, 2010, the conversion rate shall be increased such that the conversion price is equal to the average daily VWAP of the share (20 day backward looking). No adjustment is made to decrease the conversion rate. The conversion price was adjusted to US$4.06 per ADS based on the average daily VWAP for 20 days up to December 31, 2011.
	Upon a change of control or a termination of trading, the holders of the Notes can require the Company to repurchase all or any portion of the Notes in cash at a price that guarantees a rate of return of 15% per annum in addition to the stated coupon rate of 10% per annum.
	The Notes are guaranteed by Mr. Liansheng Miao, the chairman and CEO of the Company, and Yingli Power.  In addition, Yingli Power pledged certain ADS of the Company as the collateral for the Notes.  Upon any conversion of the Notes into shares of the Company, the collateral shares will be released based on a formula as defined in the indenture agreement. In no event is Yingli Power required to put any additional collateral shares.
	Management determined that the conversion feature embedded in the Notes is required to be bifurcated and accounted for as a derivative pursuant to FASB ASC Topic 815, Derivatives and Hedging.  The fair value of the conversion feature for the First Tranche as of January 16, 2009 was US$11,969 (RMB 81,538) and bifurcated from the Notes of US$20,000 (RMB 136,766) as a debt discount.  The debt discount of US$11,969 (RMB 81,538) is amortized over the three-year period the Notes are expected to be outstanding as interest expense using the effective interest rate method.  The fair value of the conversion feature increased to US$25,033 (RMB 170,893) as of May 18, 2009, the modification date as described below.  The change of US$13,064 (RMB 89,355) in the fair value of the embedded derivative liability was recognized as a loss from revaluation of embedded derivative in the consolidated statements of comprehensive loss directly.
	On May 18, 2009, the Company entered into a supplemental indenture that established a limit on the number of ordinary shares the Company is obligated to issue, as well as a covenant that prohibits the Company from issuing equity at below market price, subject to certain exceptions. As a result the embedded conversion feature of the Notes discontinued derivative accounting. The fair value of the embedded conversion feature of the First Tranche of the Notes has been classified in shareholders’ equity, with amount of US$25,033 (RMB 170,893) on the date of modification.
	At the issuance date, which is also the commitment date of the Second Tranche of the Notes, given that the market price of the ADS was far above the conversion price, all the proceeds from the Second Tranche on July 2, 2009 was recorded as beneficial conversion feature and thus credited to additional paid-in capital. The resulting debt discount of US$29,449 (RMB 201,210) is amortized over 2.5 years, representing the period of the senior secured convertible note is expected to be outstanding as additional non-cash interest expense using the straight line method.
	On June 10, 2009, US$8,721 (RMB 59,596) of the First Tranche of the Notes was converted to 2,000,000 ordinary shares.  In accordance with FASB ASC Topic 815-10, Derivatives and Hedging-Overall, US$4,520 (RMB 30,890), representing the relevant unamortized debt discount remaining at the date of conversion, was recorded as interest expense for the year ended December 31, 2009.
	On August 10, 2010, US$11,279 (RMB 76,410) of the First Tranche of the Notes and US$ 1,804 (RMB 12,221) of the Second Tranche of the Notes were converted to 2,586,630 and 413,714 ordinary shares, respectively. On September 21, 2010, US$13,083 (RMB 87,652) of the Second Tranche of the Notes was converted to 3,000,344 ordinary shares. US$7,514 (RMB 50,857), representing the relevant unamortized debt discount remaining at the dates of conversion was recorded as interest expense for the year ended December 31, 2010.
	On January 18, 2012, the remaining US$14,562 (RMB 92,039) of the Second Tranche of the Notes was converted to 3,588,025 ordinary shares. US$7,464 (RMB 47,178), representing the relevant unamortized debt discount remaining at the dates of conversion was recorded as interest expense for the year ended December 31, 2012.  As a result, the senior secured convertible notes have been fully converted accordingly.

	On October 13, 2010, Tianwei Yingli registered its plan to issue up to RMB 2,400,000 RMB-denominated unsecured five-year medium-term notes (the “Registered Issue”) with the PRC National Association of Financial Market Institutional Investors (“NAFMII”).  The Registered Issue allows Tianwei Yingli to issue RMB-denominated unsecured five-year medium-term notes in two tranches on the PRC inter-bank debenture market. The First Tranche Issue with RMB 1,000,000 was completed on October 13, 2010 and will mature on October 13, 2015. Tianwei Yingli has an option to call the notes at the end of the third year from issuance. Upon exercise of the call option, the re-purchase amount equals to the par value of the notes plus any unpaid interest. The First Tranche bears a fixed annual interest rate of 4.3% per annum in the first three years, and increased to 5.7% per annum in the remaining two years as Tianwei Yingli chose not to call the notes on October 13, 2013.
	The Company did not exercise the call option at the end of the third year from issuance and computed the effective interest rate of 4.82% evenly for the entire contract term of 5 years.
	On May 10, 2011, the second tranche of the medium-term notes with a principle amount of RMB 1,400,000, or the Second Tranche Issue, was issued and will mature on May 12, 2016. The Second Tranche Issue bears a fixed annual interest rate of 6.15%.
	In March 2012, Yingli China registered its plan to issue up to RMB 1,500,000 RMB-denominated unsecured three-year and five-year medium-term notes (the “Yingli China Registered Issue”) with the NAFMII.  The Yingli China Registered Issue allows Yingli China to issue RMB-denominated unsecured three-year and five-year medium-term notes in two tranches on the PRC inter-bank debenture market. On May 3, 2012, the first tranche issue with RMB 1,200,000 at a fixed annual interest rate of 5.78% and the second tranche issue with RMB 300,000 at a fixed annual interest of 6.01% were issued with maturity on May 3, 2015 and May 3, 2017, respectively.

	In September 2009, Yingli China and two other entities, unrelated to the Company, contributed RMB 100,000, RMB 60,000 and RMB 40,000, to establish Yingli Hainan, with equity interest of 50%, 30% and 20%, respectively. In 2010, Yingli China and these two entities, contributed RMB 150,000, RMB 90,000 and RMB 60,000 to Yingli Hainan, respectively. Through an agreement with the 30% equity owner, Yingli China is committed, within a period of three years, to purchase the 30% equity ownership at RMB 150,000 plus interest expenses at a 3-year bank borrowing rate. Any equity return distributed to the 30% equity owner prior to the purchase will be refunded to Yingli Hainan, which is exclusively for the beneficiary of Yingli China.
	Yingli Hainan was determined to be a variable interest entity (“VIE”). Through the agreement, Yingli China absorbs 80% of Yingli Hainan’s expected losses and receives 80% of Yingli Hainan’s expected residual returns and therefore Yingli China has determined that it is the primary beneficiary of Yingli Hainan. The financial statements of Yingli Hainan have been included in the consolidated financial statements of the Company and 20% variable interest not held by the Company is presented as noncontrolling interest. RMB 150,000 cash contribution from the 30% equity owner was accounted for by the Company as a financing arrangement pursuant to FASB ASC Subtopic 480-10, Distinguishing Liabilities from Equity-Overall. A liability of RMB 157,654 representing the 30% equity owner’s cash contribution of RMB 150,000 plus accrued unpaid interest was recorded as of December 31, 2010.
	In January 2011, Yingli China purchased the 30% equity interest at RMB 150,000 (US$23,833). As a result, Yingli Hainan ceased to be a VIE and became a majority-owned subsidiary of Yingli China. The interest of RMB 6,419 is included in “other current liabilities and accrued expenses” in the consolidated balance sheet as of December 31, 2012 and was paid in 2013.
	In November 2012, a third party contributed RMB 100,000 to Yingli Hainan to acquire 5.825% equity interest of Yingli Hainan.  Pursuant to the agreement between Yingli China and the investor, Yingli China is obligated to purchase such equity interest from the investor in the amount of RMB 100,000 plus 5% annual interest in 5 years.  In December 2013, another third party contributed RMB 100,000 to Yingli Hainan to acquire 5.50% equity interest of Yingli Hainan.  Pursuant to the agreement between Yingli China and the investor, Yingli China is obligated to purchase such equity interest from the investor in the amount of RMB 100,000 plus 6.15% annual interest in 2 years.  Because of Yingli China’s contractual obligations to purchase the equity interests from these investors, the equity contributions made by the investors plus accrued interest in the amount of RMB 207,067 (US$34,205) have been recorded in “other non-current liabilities” in the consolidated balance sheet as of December 31, 2013.

	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 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. As a result, the Company recognized a provision of RMB 851,694 on its firm purchase commitments under the long-term fixed price polysilicon contracts as of December 31, 2011.  The provision was determined by applying a methodology similar to that used in the lower of cost or market evaluation with respect to inventory.  During the years ended December 31, 2011 and 2012, notwithstanding that the firm purchase commitments under the long-term fixed price contracts continued to be in effect, through negotiations with the vendors the Company was able to obtain various pricing concessions from the vendors which resulted in the actual purchase price paid by the Company to be less than the stated contract price.  The Company has therefore reclassified the accrual for potential losses on inventory firm purchase commitments of RMB 851,694 as of December 31, 2012 to an accrual for loss contingency related to the inventory purchase commitments.
	During the year ended December 31, 2013, the Company continued to negotiate and execute amendments for current purchases on a monthly or quarterly basis with two of the vendors and obtained price concessions that allowed the Company to purchase polysilicon at renegotiated prices that were in line with the market price and significantly lower than the stated contract prices under the long-term fixed price supply contracts with these vendors.  In addition, the Company continued to negotiate with these two vendors for an overall amendment to each long-term fixed price supply contract with such vendors to eliminate fixed price arrangements.  In October 2013, the Company entered into agreements with one of the two vendors 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.  The Company has not reached similar agreement with the other vendor, but continued to renegotiate prices on a quarterly or monthly basis to purchase at close to market prices. The Company failed, however, to purchase from the vendor the stated quantities for a total of six months in 2012 and 2013 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, the vendor claimed that it had forfeited certain advance payments made by the Company.  Notwithstanding the Company’s failure to accept deliveries for six months and the vendor’s claim as described above, the Company and the vendor continued their monthly or quarterly negotiations and the Company has accepted deliveries from the vendor after its failure to accept deliveries in those six months.
	With respect to the third vendor, the Company did not made any purchase from it under the long-term fixed price supply contract, which is effective from 2013 to 2020, due to the anti-dumping duty and anti-subsidy investigation against Solar-Grade Polysilicon launched by the Ministry of Commerce of the People’s Republic of China.  The Company has received invoices on its take-or-pay obligation for failing to take the shipments in 2013 and is currently in discussion with this vendor to seek an acceptable solution to both parties on the performance of the long-term supply contract.
	In connection with the preparation of the Company’s 2013 consolidated financial statements for the year ended December 31, 2013, management reassessed the loss contingency under the long-term fixed price polysilicon contracts taking into account the developments described above and recognized an additional provision of RMB480,182 (US$79,320) on the firm purchase commitments under the long-term fixed price polysilicon contracts as of December 31, 2013.  The provision was determined by applying a methodology similar to that used in the lower of cost or market evaluation with respect to inventory, using management’s best estimates of future purchase prices over the remaining terms of the contracts and applying such estimated purchase prices in the lower of cost or market evaluation.  In estimating the renegotiated purchase prices, the Company considered the pertinent terms of each of the long-term supply contracts, the history and progress of renegotiation with the relevant vendors and the actual price concessions granted, the polysilicon market development based on available industry research data and the likelihood of achieving different levels of renegotiated prices for future periods.  In addition to the estimated renegotiated purchase price, certain other key assumptions were used in measuring the loss accrual, which included but were not limited to (i) the estimated net realizable value of the PV modules manufactured from the polysilicon expected to be purchased under the long-term supply contracts; and (2) the normal profit margin of the PV modules for purposes of estimating the replacement cost or market price under the lower of cost or market evaluation. The Company also considered the quantities that were required to be purchased and amounts due on take or pay arrangements, as well as the history and progress of renegotiation with the relevant vendors and the actual concessions granted in developing the amount of the estimated loss contingencies.
	As of December 31, 2013, total accrual for loss on inventory purchase commitments were RMB 1,331,877 (US$220,010), of which RMB 87,134 (US$14,393), has been recorded as a reduction “prepayment to suppliers” in relation to the failure to purchase the stated quantities for a total of six months in 2012 and 2013 under the long-term fixed price supply contracts with one vendor as described above, RMB 144,082 (US$23,801) has been recorded in “other current liabilities and accrued expenses” based on the stated delivery schedules through the end of 2014 under the supply contracts and the remaining balance of RMB 1,100,661 (US$181,816) has been recorded in “other liabilities”.

	PRC
	The Company’s PRC subsidiaries file separate income tax returns.  Effective from January 1, 2008, under the new Enterprise Income Tax Law (the “new EIT law”), the Company’s PRC subsidiaries are subject to PRC income tax at the statutory rate of 25%, except for the followings.
	·                                Prior to January 1, 2008, Tianwei Yingli was entitled to a 2-year full exemption from income tax followed by a 3-year 50% reduction in the income tax rate (“2+3 tax holiday”) starting from its first profit-making year from a PRC income tax perspective.  Tianwei Yingli commenced its 2+3 tax holiday in 2007.  The new EIT law and its relevant regulations grandfather the 2+3 Holiday. Accordingly, Tianwei Yingli is subject to income tax at 12.5% from 2009 to 2011.
	In 2008, Tianwei Yingli was recognized by the Chinese government as a “High and New Technology Enterprise” (“HNTE”) under the new EIT law and its relevant regulations.
	In 2011, Tianwei Yingli renewed its HNTE qualification, which entitled it to the preferential income tax rate of 15% for 2012 and 2013.
	·                                In 2008, Yingli China was recognized by the Chinese government as a HNTE under the new EIT law and its relevant regulations, which entitled it to the preferential income tax rate of 15% from 2008 to 2010.  In 2011, Yingli China renewed its HNTE qualification, which entitled it to the preferential income tax rate of 15% from 2011 to 2013.
	·                                In 2009, Fine Silicon Co., Ltd. (“Fine Silicon”) was recognized by the Chinese government as a HNTE under the new EIT law and its relevant regulations, which entitled it to the preferential income tax rate of 15% from 2009 to 2011.
	·                                In 2011, Yingli Hainan was recognized by the Chinese government as a HNTE under the new EIT law and its relevant regulations. Being a HNTE located in the Hainan Special Economic Zone, Yingli Hainan is entitled to a 2+3 tax holiday starting from the year in which it first generates operating income. Yingli Hainan elected and was approved to commence its 2+3 tax holiday in 2011. Therefore, Yingli Hainan is entitled to income tax exemption for 2011 and 2012 and subject to the reduced income tax rate of 12.5% from 2013 to 2015.
	Subject to reapplication or renewal, Tianwei Yingli, Yingli China and Yingli Hainan’s HNTE status will enable them to continue to enjoy the preferential income tax rate.  Management believes that these subsidiaries meet all the criteria for the reapplication of HNTE status.
	·                                In 2013, Yingli Tianjin, Yingli Lixian and Yingli Hengshui were recognized by the Chinese government as HNTE under the new EIT law and its relevant regulations, which entitled them to the preferential income tax rate of 15% from 2013 to 2015.

In assessing the realization of deferred income tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible.  Management considers the scheduled reversal of deferred tax liabilities (including the impact of available carryforward periods), projected future taxable income, and tax planning strategies in making this assessment.
As of December 31, 2013, the Company recognized net deferred income tax assets of RMB671,824 (US$110,977), among which RMB280,059 (US$46,262) primarily relate to the tax benefits of (i) RMB538,670 (US$88,982) in gross tax loss carryforwards, which expire in varying amounts between 2016 and 2018; (ii)RMB199,781 (US$33,001) in provision for inventory purchase commitment, which expire in varying amounts upon the settlement of the contingency on the long term purchase commitment provision with the major polysilicon suppliers between 2014 and 2020.  The realization of these tax benefits is dependent on the generation of sufficient taxable income prior to expiration of the tax loss carryforwards and at the time the provision for inventory purchase commitment is tax deductible. Management believes it is more likely than not that the Company will realize the benefits of deferred income tax assets, net of the existing valuation allowances as of December 31, 2012 and 2013.  The amount of the deferred income tax assets considered realizable, however, could be reduced in the near term if estimates of future taxable income during the carryforward period are reduced.
The new EIT law and its relevant regulations impose a withholding income tax at 10%, unless reduced by a tax treaty, for dividends distributed by a PRC-resident enterprise to its immediate holding company outside the PRC for earnings accumulated beginning on January 1, 2008 and undistributed earnings generated prior to January 1, 2008 are exempt from such withholding tax.  As of December 31, 2013, the Company has not recognized a deferred income tax liability of RMB125,007 (US$20,650) for the undistributed earnings of RMB1,250,067(US$206,496) generated by the PRC subsidiaries as of December 31, 2013 as the Company plans to indefinitely reinvest these earnings in the PRC.
The German tax law and its relevant regulations impose a withholding income tax at 26.375% for dividends distributed by a Germany-resident enterprise to its immediate holding company outside Germany.
For each of the years ended December 31, 2011, 2012 and 2013, the Company did not have any unrecognized tax benefits and thus no interest and penalties related to unrecognized tax benefits were recorded.  In addition, the Company does not expect that the amount of unrecognized tax benefits will change significantly within the next 12 months. According to the PRC Tax Administration and Collection Law, the statute of limitations is three years if the underpayment of taxes is due to computational errors made by the taxpayer or the withholding agent.  The statute of limitations is extended to five years under special circumstances where the underpayment of taxes is more than RMB 100 (US$ 17).  In the case of transfer pricing issues, the statute of limitation is ten years.  There is no statute of limitation in the case of tax evasion.  The tax returns of the Company’s PRC subsidiaries for the tax years 2008 to 2013 are open to examination by the relevant tax authorities.

	On December 28, 2006, the Company adopted the 2006 Stock Incentive Plan (the “Plan”).  The Plan provides for both the granting of stock options and other stock-based awards such as restricted shares to key employees, directors and consultants of the Company. The Plan was subsequently amended by the Company’s board of directors and shareholders to increase the number of ordinary shares that the Company is authorized to issue. The amendment did not change any other provisions of 2006 Stock Incentive Plan. As of December 31, 2013, the Company is authorized to issue under the 2006 Stock Incentive Plan 12,745,438 shares. Among these shares, up to 2,715,243 shares may be issued for the purposes of granting awards of unvested shares and up to 10,030,195 shares may be issued for the purpose of granting stock option.
	Restricted shares
	On January 19, 2007, the Company’s board of directors granted 2,576,060 unvested shares for the benefit of 68 participants, consisting of 1,576,300 unvested shares granted to eight directors and officers of Yingli Green Energy and Tianwei Yingli and 999,760 unvested shares granted to 60 other employees of the Company. The unvested shares have been placed in a trust, which is controlled and managed by the Company. The shares vest with continued employment and ratably in 20% increments over a five-year period, beginning on January 19, 2008, the first anniversary following the award grant date.  The unvested shares fully vest upon termination of service resulting from death or disability of the participant that is due to work-related reasons or upon a change of control in the Company.  For a period of six months after any shares are vested, the Company has the option to purchase all or part of the vested shares at the then fair market value.  Any vested shares that are not repurchased by the Company during the six-month period would be distributed to the participant.  Share-based compensation expense with respect to the unvested shares was measured based on the estimated fair value of the Company’s ordinary shares at the date of grant of US$4.96 and is recognized on a straight-line basis over the five-year period.
	In April 2007, the Board of Directors of the Company approved the granting of 30,000 and 15,000 non-vested shares to one executive and one third-party consultant, respectively. Share-based compensation expense with respect to the unvested shares granted to the employee was measured based on the estimated stock issuance price of the Company’s IPO of US$11 at the date of grant and is recognized on a straight-line basis over the five-year period.  The Company granted unvested shares to the consultant in exchange for certain services to be provided.  The Company accounts for equity instrument issued to non-employee vendors in accordance with the provisions of FASB ASC Topic 505-50, Equity-based Payments to Non-employees (“ASC Topic 505-50”) under the fair value method.  The measurement date of the fair value of the equity instrument issued is the date on which the consultant’s performance is completed.  Prior to the measurement date, the equity instruments are measured at their then-current fair values at each of the reporting dates.  Share-based expense recognized over the service period is adjusted to reflect changes in the fair value of the Company’s ordinary shares between the reporting periods up to the measurement date.
	A summary of the non-vested restricted share activity for the years ended December 31, 2011, 2012 and 2013 is as follows:

	In November 2011, the Company reduced the exercise price and extended the vesting periods of 2,811,306 share options held by employees and management. The total incremental fair value related to the modification amounted to US$1,749, which was calculated based on the excess of the fair value of the modified share options over the fair value of the original share options at the date of the modification. The Company has separately accounted for the incremental fair value and recognizes the incremental fair value as share-based compensation expense over the period from the modification date to the date when the modified share option vest, with the unamortized compensation cost from original award recognized over the remainder of the original vesting period.  The modified share options were included in the number of share options forfeited or cancelled and number of share options granted for the year ended December 31, 2011.
	The Company accounts for stock options in accordance with ASC Topic 718, by recognizing compensation cost based on the grant-date fair value over the period during which an employee is required to provide service in exchange for the award.  No income tax benefit was recognized in the consolidated statements of comprehensive loss for these share options as such compensation expenses are not deductible for PRC tax purposes.  The amount of compensation cost recognized for stock options for the years ended December 31, 2011, 2012 and 2013 is as follows:

	As of December 31, 2013, commitments outstanding for the purchase of property, plant and equipment approximated RMB 1,723,809 (US$284,753).
	In order to secure adequate and timely supply of polysilicon, the Company entered into a number of multi-year supply agreements from 2006 through 2011.
	A portion of the Company’s multi-year supply agreements are structured as “take or pay” arrangements which allow the supplier to invoice the Company for the full purchase price of polysilicon the Company is obliged to purchase each year at predetermined prices, whether or not the Company actually ordered the required volume, purchase obligations under “take or pay” arrangements are as follows:
	Year ending December 31,	RMB	US$
	2014	2,907,305	480,253
	2015	2,747,669	453,883
	2016	2,614,709	431,919
	2017	2,553,336	421,781
	2018	2,792,683	461,318
	Thereafter	2,591,183	428,033
	Total	16,206,885	2,677,187
	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 in the amount of RMB 735,646 and RMB 415,075 (US$68,566) under the “take or pay” arrangements during 2012 and 2013, respectively.
	Besides the “take or pay” arrangements, future minimum obligations under other polysilicon supply agreements amounted to RMB 8,287,869 (US$ 1,369,058) as of December 31, 2013.  The Company purchased polysilicon in the amount of RMB 397,241 and RMB 732,626 (US$121,021) under the multi-year supply agreements during 2012 and 2013, respectively.
	In October 2012, the Company received notice of an antitrust and unfair competition lawsuit filed by Solyndra, LLC (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. A case management conference has been set for April 23, 2014, at which the court will likely set a schedule for the remainder of the Solyndra litigation. While it is premature at this stage of the litigations to evaluate the likelihood of favorable or unfavorable outcomes, the Company believes that Solyndra’s claims lack merits and would defend itself vigorously against those allegations.  In accordance with ASC Topic 450, no accrual of loss contingency was accrued as of December 31, 2013 since it is not probable that a liability has been incurred and the amount of loss cannot be reasonably estimated.
	From July 2009 through March 2013, the Company signed a series of agreements and amendments with suppliers to provide recovery service of exhausted slurry for the Company.  According to the series of agreements and amendments with the supplier, the Company guaranteed a minimum annual supply volume of exhausted slurry.  The Company didn’t provide adequate supply volume of exhausted slurry in 2012 due to some quality issue noted on the supplier’s services.  In May 2013, the supplier informed the Company that it would like to cease the recovery service and claimed compensation.  The Company has not received any notices from any arbitration tribunal or courts.  While it is premature at this stage to evaluate the final outcome, the Company believes that the supplier’s claims lack merits.  In accordance with ASC Topic 450, no accrual of loss contingency was accrued as of December 31, 2013 since it is not probable that a liability has been incurred and the amount of loss cannot be reasonably estimated.
	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.  The Company believes, after consultation with the legal counsel, that these allegations are without merit. The Company intends to defend vigorously against those allegations. In accordance with ASC Topic 450, no accrual of loss contingency was accrued as of December 31, 2013 since it is not probable that a liability has been incurred and the amount of loss cannot be reasonably estimated.

	(a)                       Goodwill
	Based upon indicators of impairment in 2011, which included a significant decrease in market capitalization and a decline in recent operating results, the Company performed an impairment test as of December 31, 2011. The Company represents the single reporting unit as at December 31, 2011 for goodwill impairment test. The first step test resulted in the determination that the fair value of the Company was less than the carrying value of its net assets, including goodwill. The fair value of the Company is determined based on quoted market prices and a control premium. As a result of the second step test, the Company estimated the implied fair value of the goodwill compared to carrying amounts and recorded an impairment charge of RMB 273,382 to fully impair the goodwill as of December 31, 2011.

	Technical know-how represents self-developed technologies, which were feasible at the acquisition date and technologies contributed by a noncontrolling interest holder of a subsidiary of the Company. 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.
	The aggregated amortization expense for intangible assets for the years ended December 31, 2011, 2012 and 2013 is as follows:

Summary of Significant Accounting Policies and Significant Concentrations and Risks (Policies)	12 Months Ended
	Dec. 31, 2013
Summary of Significant Accounting Policies and Significant Concentrations and Risks	'
Basis of Presentation	'
	(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.
	For the year ended December 31, 2013, the Company incurred a net loss of RMB 2,054,898 (US$ 339,444). As of December 31, 2013, the Company had cash, cash equivalents and restricted cash of RMB 2,797,808 (US$ 462,165) and short-term bank borrowings, including current portion of long-term bank borrowings of RMB 6,715,877 (US$ 1,109,384). The liquidity of the Company is primarily depending on its ability to maintain adequate cash flows from operations, to renew its short-term bank loans and to obtain adequate external financing 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 ending December 31, 2014. Based on such forecast, management believes that adequate sources of liquidity exist to fund the Company’s working capital and capital expenditures requirements, and to meet its short term debt obligations and other liabilities and commitments as they become due. In preparing the cash flow forecast, management has considered historical cash requirements of the Company, as well as other key factors, including its ability to renew its short-term bank borrowings during 2014. If available liquidity is not sufficient to meet the Company’s operating and debt service obligations as they become due, management’s plans include pursuing alternative financing arrangements or reducing expenditures as necessary to meet the Company’s cash requirements throughout 2014.  However, there is no assurance that, if required, the Company will be able to raise additional capital or reduce discretionary spending to provide the required liquidity.
Principles of Consolidation	'
	(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 equity interest not held by the Company is presented as noncontrolling interests. All significant inter-company balances and transactions have been eliminated upon consolidation.
Significant Concentrations and Risks	'
	(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 100%, 91% and 90% of its total net revenues for the years ended December 31, 2011, 2012 and 2013, respectively, from sales to customers in countries with known government incentive programs for the use of solar products. A significant reduction in the scope or discontinuation of government incentive programs would have a materially adverse effect on the demand of the Company’s products.
	A significant portion of the Company’s net revenues are from customers located in Germany, the United States of America (“USA”) and PRC.  Revenues from customers located in Germany, USA and PRC are as follows:
		Year ended
		December 31,	% of net		December 31,		% of net		December 31, 2013		% of net
		2011	revenue		2012		revenue				revenue
		RMB			RMB				RMB	US$
	Germany	6,595,109	45	%	4,765,312		42	%	2,439,058	402,904	18	%
	USA	2,137,219	15	%	1,600,695		14	%	2,906,262	480,080	22	%
	PRC	3,261,886	22	%	2,653,341		23	%	4,546,482	751,025	34	%
	Total	11,994,214	82	%	9,019,348		79	%	9,891,802	1,634,009	74	%
	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 2011, 2012 and 2013, sales to the top five customers accounted for approximately 27.7%, 26.0% and 15.2%, respectively, of the Company’s net revenues.
	As of December 31, 2012 and 2013, the top five outstanding accounts receivable balance (net of provisions) accounted for approximately 24.2% and 20.1%, respectively, of the Company’s total outstanding accounts receivable.
	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 1,703,312 and RMB 1,682,521 (US$ 277,933) as of December 31, 2012 and 2013, respectively.  The Company makes the prepayments without receiving collateral for such payments.  As a result, the Company’s claims for such prepayments would rank only as an unsecured claim, which exposes the Company to the credit risks of the suppliers. As of December 31, 2012 and 2013, advances made to individual suppliers in excess of 10% of total prepayments to suppliers are as follows:
			December 31,
			2012		2013
		Location	RMB		RMB		US$
	Supplier A	Singapore	184,523		210,343		34,746
	Supplier B	South Korea	230,108		158,040		26,106
	Supplier C	Germany	958,284		900,821		148,805
	Total		1,372,915		1,269,204		209,657
	The Company obtains some equipment 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 229,181 and RMB 122,340 (US$ 20,209) as of December 31, 2012 and 2013, respectively, for the purchase of equipment without receiving collateral for such payments.  As a result, the Company’s claims for such payments would rank only as an unsecured claim, which exposes the Company to the credit risks of the equipment suppliers.

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, 2012 and 2013, the Company had cash balances at three PRC individual financial institutions that held cash balances in excess of 10% of the Company’s total cash balances. These bank deposits collectively accounted for approximately 42.4% and 41.7% of the Company’s total cash balances as of December 31, 2012 and 2013, respectively.  Management believes that these financial institutions are of high credit quality.
Use of Estimates	'
	(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, goodwill and intangible assets, the fair value of share-based payments, the collectibility 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 assumptions.
Foreign Currency	'
	(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 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 fully 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 2013 RMB amounts have been translated into U.S. dollar amounts at the rate of RMB 6.0537 to S$1.00, the noon buying rate in the City of New York for cable transfers of RMB per U.S. dollar as set forth in the H.10 weekly statistical release of the Federal Reserve Board, as of December 31, 2013. No representation is made that RMB amounts could have been, or could be, converted into U.S. dollars at that rate or at any other certain rate on December 31, 2013, or at any other date.
Cash, Cash equivalents and Restricted Cash	'
	(f)                          Cash, Cash equivalents and Restricted Cash
	Cash and cash equivalents consist of cash on hand, cash in bank accounts, and interest bearing savings accounts with an initial term of three months or less.
	Restricted cash of RMB 966,878 and RMB 1,692,330 (US$ 279,553) as of December 31, 2012 and 2013, respectively, represents bank deposits for securing letters of credit and letters of guarantee granted to the Company, primarily for the purchase of inventory and equipment and the guarantee of the offshore bank borrowings. Such letters of credit and letters of guarantee expire within one year. The cash flows from bank deposits as the guarantee of the offshore bank borrowings are reported within cash flows for financing activities in the consolidated statements of cash flows.  The cash flows from the bank deposits relating to purchases of inventory and equipment are reported within cash flows from operating activities and investing activities in the consolidated statements of cash flows, respectively.
Accounts Receivable	'
	(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 2012 and 2013, the Company entered into agreements to sell without recourse certain accounts receivable to several PRC banks. The buyer is 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 has 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 223,273 and RMB 677,795 (US$ 111,964) for the years ended December 31, 2012 and 2013, respectively, and has included the proceeds in net cash provided by operating activities in the consolidated statements of cash flows. The Company recorded a loss on the sale of accounts receivable of RMB 2,100 and RMB 11,840 (US$ 1,956) for the years ended December 31, 2012 and 2013, respectively, which is included in general and administrative expense.
Inventories	'
	(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.
Prepayments to Suppliers	'
	(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 balance of the “prepayments to suppliers” is reduced and reclassified to ‘‘inventories’’ when inventory is received and passes quality inspection. Such reclassifications of RMB 476,113, RMB 495,679 and RMB 245,906 (US$40,621) for the years ended December 31, 2011, 2012 and 2013, respectively, are not reflected as cash outflows from operating activities.  In addition, the Company agreed with one of its polysilicon suppliers, pursuant to which the Company offset the balance of prepayment to the supplier against the balance of accounts payable in the amount of US$23,338 (RMB141,281) during 2013.  As of December 31, 2012 and 2013, prepayments to suppliers of RMB 1,280,131 and RMB 884,562 (US$ 146,119), respectively, representing the portion expected to be utilized after twelve months have been classified as “long-term prepayments to suppliers” in the consolidated balance sheets and relate to prepayments to suppliers for long-term supply agreements with deliveries scheduled to commence beyond the next twelve months at each respective balance sheet date.
Long-lived Assets	'
	(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.  The estimated useful lives of property, plant and equipment are as follows:
	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.
	Project assets
	Project assets consist primarily of costs relating to solar power projects in various stages of development that are capitalized prior to the sale of the solar power project.  These costs include modules, installation and other development costs.  While the project assets are not constructed for a specific customer, the Company intends to sell the project assets upon their completion.  As of December 31, 2012 and 2013, RMB63 million and RMB 356 million (US$ 59 million) of project assets were included in the construction in progress
	Goodwill and Other Intangible Assets
	Goodwill is an asset representing the future economic benefits arising from other assets acquired in a business combination that are not individually identified and separately recognized. Goodwill and trademarks, which 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. The Company’s amortizable intangible assets consist of technical know-how, customer relationships, order backlog and short-term supplier agreements with the following estimated useful lives:
	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. See note (5) to the consolidated financial statements.
	Goodwill and intangible assets that are not subject to amortization are tested annually for impairment, 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 goodwill, the impairment test is a two step test. Under the first step, the fair value of the reporting unit is compared with its carrying value (including goodwill). If the fair value of the reporting unit is less than its carrying value, an indication of goodwill impairment exists for the reporting unit and the entity must perform step two of the impairment test (measurement). Under step two, an impairment loss is recognized for any excess of the carrying amount of the reporting unit’s goodwill over the implied fair value of that goodwill. The implied fair value of goodwill is determined by allocating the fair value of the reporting unit in a manner similar to a purchase price allocation and the residual fair value after this allocation is the implied fair value of the reporting unit goodwill. If the fair value of the reporting unit exceeds its carrying value, step two does not need to be performed.
	The Company performs its annual impairment review of goodwill at December 31, and when a triggering event occurs between annual impairment tests. At December 31, 2011, the Company recognized a full impairment loss of RMB 273,382 on the goodwill. See note (22) to the consolidated financial statements.
	Government grant
	Government grants are recognized in the balance sheet initially when there is reasonable assurance that they will be received and that the Company will comply with the conditions attaching to them.
	For the year ended December 31, 2011, the Company received government grants of RMB 125,599 related to the construction of the solar power plants and the procurement of machineries, which were recognized as long-term other liabilities.
	For the year ended December 31, 2012, the Company received government grants of RMB 213,976 related to the construction of the solar power plants and the procurement of machineries, which were recognized as long-term other liabilities.
	For the year ended December 31, 2013, the Company received government grants of RMB 350,028 (US$ 57,821) related to the construction of the solar power plants and the procurement of machineries, which were recognized as long-term other liabilities.
	These grants are amortized as the related assets are depreciated or amortized. The grants amortized amounted to RMB9,484, RMB 13,130 and RMB 53,419 (US$ 8,824) for the year ended December 31, 2011, 2012 and 2013, respectively.
Land Use Rights	'
	(k)                       Land Use Rights
	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 years.
Equity Investments	'
	(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 investee, are accounted for using the equity method of accounting. Under the equity method of accounting, the Company’s share of the investee’s results of operations is included in other income (expense) in the Company’s consolidated statements of comprehensive loss. Equity investments are accounted for under the 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 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 2011, the Company recognized an impairment loss of RMB 8,720 on its equity investment. See note (8) to the consolidated financial statements.
Statutory Reserves	'
	(m)                    Statutory Reserves
	In accordance with the relevant laws and regulations of the PRC, PRC enterprises are required to transfer 10% of their after tax profit, as determined in accordance with PRC accounting standard and regulations to a general reserve fund until the balance of the fund reaches 50% of the registered capital of the enterprise. The transfer to this general reserve fund must be made before distribution of dividends can be made.  As of December 31, 2012 and 2013, the PRC subsidiaries of the Company had appropriated RMB 461,623 and RMB 484,077 (US$ 79,964), respectively, to the general reserve fund, which is restricted from being distributed to the Company, and if applicable, to the noncontrolling interests.
Derivative Financial Instruments and Hedging Activities	'
	(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 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 20 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 earnings. When it is probable that a forecasted transaction will not occur, the Company discontinues hedge accounting and recognizes immediately in earnings gains and losses that were accumulated in other comprehensive income related to the hedging relationship.
Share-based Payment	'
	(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.  The Company applies the fair value method for equity instrument issued to non-employee under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 505-50, Equity-based Payments to Non-employees (“ASC Topic 505-50”).
Revenue Recognition	'
	(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 collectibility is reasonably assured.  These criteria as they relate to the sale of the Company’s products or services are as follows:
	For all sales, the Company requires a contract or purchase order which quantifies pricing, quantity and product specifications.
	For sales of PV modules from PRC to foreign customers, delivery of the products occurs at the point in time 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 in time 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 to 3 months, and requires advance payments from the customer.
	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.  Revenue is recognized on a percentage-of-completion basis, based on the ratio of total costs incurred to date to total projected costs.  Provisions are made for the full amount of any anticipated losses on a contract-by-contract basis.  The Company recognized nil loss for these types of contracts for the year ended December 31, 2013.  Costs in excess of billings are recorded where costs recognized are in excess of amounts billed to customers of purchased commercial solar power stations. Costs in excess of billings as of December 31, 2013 amounted to RMB 216,759 (US$35,806), and are included in accounts receivable in the consolidated balance sheets.
	Other revenue consists primarily of the sale of raw materials. Delivery for the sale of raw materials occurs at the point in time the product is delivered to the customer, which is when the risks and rewards of ownership have been transferred. Delivery is evidenced by a signed customer acceptance form.
	Shipping and handling fees billed to customers are recorded as revenues, and the related shipping or delivery costs of RMB290,746, RMB 320,727 and RMB 405,839 (US$ 67,040) are recorded as selling expenses for the years ended December 31, 2011, 2012 and 2013, respectively.
	Advance payments received from customers for the 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 the PRC, value added tax (“VAT”) at a general rate of 17% on invoice amount is collected on behalf of tax authorities in respect of the sales of product and services and is not recorded as revenue.  VAT collected from customers, net of VAT paid for purchases, is recorded as a liability until it is paid to the tax authorities.
Research and Development	'
	(q)                      Research and Development
	Research and development costs are expensed as incurred. Its research and development costs consist primarily of compensation and related costs for personnel, material, supplies, equipment depreciation and laboratory testing costs.
Employee Benefits Plans	'
	(r)                        Employee Benefits Plans
	Pursuant to the relevant PRC regulations, the Company is required to make contributions for each PRC employee at a rate of 20% on a standard salary base as determined by the local Social Security Bureau, to a defined contribution retirement program organized by the local Social Security Bureau. In addition, the Company is also required to make contributions for each PRC employee at rates of 7.5%-10%, 1%-2%, 10%-12% and 1.2%-1.6% of standard salary base for medical insurance benefits, unemployment, housing fund and other statutory benefits, respectively.  Total amount of contributions for the years ended December 31, 2011, 2012 and 2013 was RMB 177,714, RMB 244,108 and 266,134 (US$ 43,962), respectively.
Warranty Cost	'
	(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-year and 25-year warranty guaranteeing 90% and 80% of initial power generation capacity, respectively. With effect from October 1, 2011, the Company implemented a new and improved warranty terms for multicrystalline PV module that guarantees 91.2% and 80.7% of initial power generation capacity for 10 years and 25 years, respectively.  Further, in respect of monocrystalline Panda PV module, the Company guarantees 98.0%, 92.0% and 82.0% of initial power generation for the first year, 10 years and 25 years, respectively. In addition, based on customers’ specific requirements, the Company provides the multicrystalline PV modules with linear-based warranty which guarantees each year’s power output during the twenty-five-year warranty period. The Company bears the risk of warranty claims long after the Company has sold its products and recognized revenues. The Company has sold PV modules since January 2003, and none of the Company’s PV modules has been in use for the entire warranty periods. In connection with the Company’s PV system sales in the PRC, the Company provides a one- to five- year warranty against defects in the Company’s modules, storage batteries, controllers and inverters.
	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.
	Changes in the carrying amount of accrued warranty liability are as follows:
		Year Ended December 31,

Firm Purchase Commitment	'
	(t)                          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. The Company recognized a provision for inventory purchase commitments of RMB 851,694 in 2011 and RMB 480,182 (US$ 79,320) in 2013. See note (16) to the consolidated financial statements.
Income Taxes	'
	(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	'
	(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	'
	(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, as that term is defined by FASB ASC Topic 280, Segment reporting.
Earnings Per Share	'
	(x)                       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 Measurements	'
	(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 (7) to the consolidated financial statements.
Recently Issued Accounting Standards	'
	(z)                         Recently Issued Accounting Standards
	In February 2013, the FASB issued ASU 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income (“ASU 2013-02”). The standard requires that companies present either in a single note or parenthetically on the face of the financial statements, the effect of significant amounts reclassified from each component of accumulated other comprehensive income based on its source (e.g., the release due to cash flow hedges from interest rate contracts) and the income statement line items affected by the reclassification (e.g., interest income or interest expense). If a component is not required to be reclassified to net income in its entirety (e.g., the net periodic pension cost), companies would instead cross reference to the related footnote for additional information (e.g., the pension footnote). ASU 2013-02 is effective for interim and annual reporting periods beginning after December 15, 2012. The Company adopted the new standard on January 1, 2013. The adoption did not have a material impact on its consolidated financial statements or related disclosures.
	In July 2013, the FASB issued ASU 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.  ASU 2013-11 requires an unrecognized tax benefit, or a portion of an unrecognized tax benefit, to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward.  ASU 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2014.  The new standard is to be applied prospectively but retrospective application is permitted.  The adoption is not expected to have a material impact on the Company’s consolidated financial statements and related disclosures.
