SUMMARY OF PRINCIPAL ACCOUNTING POLICIES

12 Months Ended

Dec. 31, 2013

SUMMARY OF PRINCIPAL ACCOUNTING POLICIES

SUMMARY OF PRINCIPAL ACCOUNTING POLICIES

2. SUMMARY OF PRINCIPAL ACCOUNTING POLICIES

(a) Basis of presentation

The consolidated financial statements have been prepared and presented in accordance with accounting principles generally accepted in the United States of America (“US GAAP”).

The accompanying consolidated financial statements have been prepared assuming that we will continue as a going concern, 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 generate cash flows from operations, and the Company’s ability to arrange adequate financing arrangements, including the renewal or rollover of its bank borrowings, to support its working capital requirements.

The following factors raise doubt about our ability to continue as a going concern for the foreseeable future.

· The solar industry is being negatively impacted by a number of factors including excess capacity, reduction of government incentives in key solar markets, higher import tariffs and the European debt crisis. These factors have contributed to declining average selling prices (“ASP”) for our products. Since December 31, 2010 the Company’s selling price of wafers and modules has fallen from $0.88 per watt (“W”) and $1.85/W, respectively, to $0.22/W and $0.65/W in 2013, respectively.

· For the year ended December 31, 2013, we incurred an operating loss of $221,445,399.

· As of December 31, 2013, our current liabilities exceed our current assets by $506,174,499. While the Company had cash and cash equivalents of $86,772,678, it had short-term bank borrowings of $ 629,177,762 all due within one year and the current portion of long-term debt amounting to $43,918,386, which is not expected to be renewed.

These factors are mitigated by the following plans and actions:

· The Company has performed a review of its cash flow forecast for the twelve months ending December 31, 2014. The Company believes that its operating cash flow in 2014 will be positive. While management believes the forecast is based on reasonable assumptions include: the ASP of wafers and module is estimated to be approximately $0.22/W and $0.65/W, respectively, for the year ending December 31, 2014, and the cost to produce of approximately $0,22/W and 0.61/W, respectively, for the year ending December 31, 2014, as a result of certain technology improvements.

· While there can be no assurance that the Company will be able to refinance its short-term bank borrowings as they become due, historically, the Company has renewed or rolled over most of its short-term bank loans upon the maturity date of the loans and has assumed it will continue to be able to do so. As of March 31, 2014, the Company successfully rolled-over $200 million short-term borrowings outstanding as of December 31, 2013.

· As of March 31, 2014, the Company has unused lines of credit of $117M, of which $92M is related to trade financing. Based on the Company’s historical experience, trade facilities funding request will be approved in the normal course provided that the Company submits the required supporting documentation and the amount is within the credit limit granted.

· In December 2013, the Company signed a Memorandum of Intent to sell three power station projects in Western China, with a total capacity of 60MW, to Jiangsu Akcome Solar Science & Technology Co., Ltd. on December 30, 2013, pursuant to which the share transfer agreement was subsequently entered into on January 3, 2014. The share transfer will generate positive cash inflow in 2014.

· In March 2014, the Company received non-binding letters of commitment from three banks to support their financing in the amount of $376.8 million, of which $159.2 million is related to short term loan and $217.6 million related to trade financing. Subsequent to receiving the commitments, the Company has obtained financing under the terms of the agreements. However, the non-binding letters of commitment from banks do not have a stated term, and may be withdrawn by the banks at their discretion.

Based on the above factors, management believes that adequate sources of liquidity will exist to fund the Company’s working capital and capital expenditures requirements, and to meet its short term debt obligations, other liabilities and commitments as they become due.

(b) Basis of consolidation

The consolidated financial statements include the financial statements of ReneSola and its subsidiaries. All inter-company transactions, balances and unrealized profits and losses have been eliminated on consolidation.

(c) Fair value measurement

The Company estimates fair value of financial assets and liabilities as the price that would be received from the sales of an asset or paid to transfer a liability (an exit price) on the measurement date in an orderly transaction between market participants.

(d) Use of estimates

The preparation of consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses for the reporting periods presented. Actual results could materially differ from these estimates. Significant accounting estimates which are susceptible to change as more information becomes available include allowances for doubtful receivables and advances to suppliers, lower of cost or market charges and other provisions for inventories, valuation of deferred tax assets, accruals of warranty costs, useful lives of property, plant and equipment and recoverability of the carrying value of long-lived assets and assets held-for-sale, impairment of goodwill and intangible assets, valuation of project assets.

(e) Cash and cash equivalents

Cash and cash equivalents represent cash on hand and held with banks, including demand deposits, which are unrestricted as to withdrawal and use, and which have original maturities of three months or less when purchased.

(f) Restricted cash

Restricted cash represents amounts held by banks, which are not available for the Company’s general use, as security for issuance of letters of credit, bank acceptance bills, bank borrowings and bank drafts. Upon maturity of the letters of credit and repayment of bank acceptance bills, bank borrowings and bank drafts which generally occur within one year, the deposits are released by the bank and become available for general use by the Company.

(g) Inventories

Inventories are stated at the lower of cost or market. Cost is determined by the weighted-average method for work-in-process and finished goods and by the first-in-first-out method for raw materials. Inventory costs comprise direct materials, direct labor and those overhead costs that have been incurred in bringing the inventories to their present location and condition.

Adjustments are recorded to write down the cost of obsolete and excess inventory to the estimated market value based on historical and forecast demand. The estimated market value is measured as the estimated selling price of each class of the inventories in the ordinary course of business less estimated costs of completion and disposal and normal profit margin.

The Company outsources portions of its manufacturing process, including cutting ingots into wafers, converting wafers into solar cells and converting solar cells or wafers into modules, to various third-party manufacturers. These outsourcing arrangements may or may not include transfer of title of the raw material inventory (ingots or wafers) sent to the third-party manufacturers.

For the outsourcing arrangements in which title does not transfer, the Company maintains such inventory on the Company’s balance sheet as raw materials inventory while it is in physical possession of the third-party manufacturer. Upon receipt of the processed inventory, it is reclassified as work-in-process inventory and the processing fees paid are capitalized as cost of inventory.

For those outsourcing arrangements in which title (including risk of loss) does transfer to the third-party manufacturer, the Company is contractually obligated to repurchase the processed inventory. To accomplish this, it enters into raw material sales agreements and processed inventory purchase agreements simultaneously with the third-party manufacturer. In such instances, where they are, in substance tolling arrangements, the Company retains the inventory in the consolidated balance sheets while it is in the physical possession of the third-party manufacturer. The cash received from the third-party manufacturer is recorded as a current liability on the balance sheet rather than revenue or deferred revenue. Upon receipt of the processed inventory, it is reclassified from raw materials to work-in-progress inventory and the processing fee paid to the third-party manufacturer is added to inventory cost. Cash payments for outsourcing arrangements which require prepayment for repurchase of the processed inventory are classified as current assets on the balance sheet. If there is no legal right of offset established by these arrangements, the associated assets and liabilities are presented separately on the balance sheet until the processed inventory is returned to the Company.

The Company provides solar wafer processing services on behalf of third parties who have their own polysilicon supplies. Under certain of these solar wafer processing service arrangements, the Company purchases raw materials from a customer and agrees to sell a specified quantity of solar wafers produced from such materials back to the same customer. The quantity of solar wafers sold back to the customer under these processing arrangements is consistent with the amount of raw materials purchased from the customer based on current production conversion rates. The Company records revenue from these processing transactions based on the amount received for solar wafers sold less the amount paid for the raw materials purchased from the customer. The revenue recognized is recorded as solar wafer processing revenue and the production costs incurred related to providing the processing services are recorded as solar wafer processing costs within cost of revenue.

The Company also provides module processing services on behalf of third parties who have their own cell supplies. Under certain of these module processing service arrangements, the Company purchases cells from a customer and agrees to sell a specified quantity of modules produced from such materials back to the same customer. The quantity of modules sold back to the customer under these processing arrangements is consistent with the amount of cells purchased from the customer based on current production conversion rates. The Company records revenue from these processing transactions based on the amount received for modules sold less the amount paid for the cells purchased from the customer. The revenue recognized is recorded as module processing revenue and the production costs incurred related to providing the processing services are recorded as module processing costs within cost of revenue.

On occasion, the Company enters into firm purchase commitments to acquire materials from its suppliers. A firm purchase commitment represents an agreement that specifies all significant terms, including the price and timing of the transactions, and includes a disincentive for nonperformance that is sufficiently large to make performance probable. This disincentive is generally in the form of a “take or pay” provision which requires the Company to pay for committed volumes regardless of whether the Company actually takes possession of the materials. The Company evaluates these agreements whenever market prices decrease such that the commitment price is significantly higher than market, if any, using a lower of cost or market approach consistent with that used to value inventory (see Note 4).

(h) Project assets

In 2012, the Company began entering into arrangements to develop commercial solar power systems (“project assets”) for sale upon their completion. Project assets consist primarily of costs relating to solar power projects in various stages of development that are capitalized prior to entering into a definitive sales agreement for the solar power project. These costs include modules, installation and other direct development costs. When all of the criteria to recognize the sale as revenue have been met. the Company expenses project assets to cost of sales for each project asset is sold to a customer. The Company generally classifies project assets as current based on the nature of a solar power project and the estimated time required to complete all activities to sell a specific project.

If the period to complete a sale extends beyond one-year, the Company will not continue to report the project assets as current, and will reclassify them to property, plant and equipment, unless the delay in the period required to complete the sale is caused by events or circumstances beyond the Company’s control. As of December 31, 2013, the Company reclassified two project assets in Bulgaria to property, plant and equipment with the carrying value of $ 16,672,267.

Project assets consisted of the following at December 31, 2013:

	At December 31,
	2012		2013
Project assets - Module cost	$	9,055,200	$	11,303,056
Project assets - Development	$	9,902,576	$	11,075,075
Project assets - Others	$	6,844,723	$	11,794,748
Total project assets	$	25,802,499	$	34,172,879

Current portion	$	25,802,499	$	34,172,879
Noncurrent portion	$	nil	$	nil

Total liabilities (all non-current liabilities)	$	4,698,269	$	33,843,600

The Company reviews project assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. In determining whether or not the project assets are recoverable, the Company considers a number of factors, including changes in environmental, ecological, permitting, or regulatory conditions that affect the project. Such changes may cause the cost of the project to increase or the selling price of the project to decrease. If a project is not considered recoverable, the Company impairs the respective project assets and adjusts the carrying value to the estimated recoverable amount, with the resulting impairment recorded within operations. The Company did not recognize any impairment losses on project assets for the years ended December 31, 2012 and 2013, respectively.

(i) Investments

Investments in marketable equity securities are classified as trading, available-for-sale, or held-to-maturity. Investments classified as trading are reported at fair value with unrealized gains and losses included in earnings. Investments classified as available-for-sale are reported at fair value with unrealized gains and losses recorded in other comprehensive income. The cost of investments sold is determined by specific identification.

Investments are evaluated for impairment at the end of each period. Unrealized losses are recorded to other expenses when a decline in fair value is determined to be other-than-temporary. The Company reviews several factors to determine whether a loss is other-than-temporary. These factors include, but are not limited to, the: (1) nature of the investment; (2) cause and duration of the impairment; (3) extent to which fair value is less than cost; (4) financial conditions and near term prospects of the issuers; and (5) ability to hold the security for a period of time sufficient to allow for any anticipated recovery in fair value.

The Company routinely reviews available-for-sale securities for other-than-temporary declines in fair value below the cost basis, and when events or changes in circumstances indicate the carrying value of an asset may not be recoverable, the security is written down to fair value. For the year ended December 31, 2011, the Company recorded other-than-temporary impairment loss on the only available-for-sale investment of $6,207,119, which represented full impairment of the asset.

(j) Advances to suppliers and advances for purchase of property, plant and equipment

In order to secure a stable supply of silicon materials and construction materials, the Company makes advance payments to suppliers for raw material supplies and advances for purchases of long-lived assets which are offset against future deliveries. Advances to suppliers for purchases expected within twelve months as of each balance sheet date are recorded as advances to suppliers in current assets and those associated with purchases expected over longer periods of time are recorded in non-current advance to suppliers. As of December 31, 2012 and 2013, advances to suppliers in current assets were $23,614,491 and $ 14,210,115, respectively, and non-current advances to suppliers for silicon raw material supplies were $5,928,000 and $ 5,627,400 respectively. Advances for property, plant and equipment are recorded in non-current assets and were $8,317,188 and $ 2,214,265 as of December 31, 2012 and 2013, respectively. The Company does not require collateral or other security against its advances to suppliers. As a result, the Company’s claims for such prepayments are unsecured, which exposes the Company to the suppliers’ credit risk. The Company performs ongoing credit evaluations of the financial condition of its suppliers.

As of December 31, 2012 and 2013, prepayments made to individual suppliers in excess of 10% of total advances and prepayments to raw material suppliers are as follows:

	At December 31,
	2012		2013
Supplier A	$	17,625,438	$	4,346,638
Supplier B	$	5,928,000	$	5,627,400

As of December 31, 2012 and 2013, advances for purchases of property, plant and equipment in excess of 10% of total advances and prepayments to equipment suppliers are as follows:

	At December 31,
	2012		2013
Supplier A	$	2,182,950	$	446,008
Supplier B	$	2,020,512	—
Supplier C	*		$	272,560
Supplier D	*		$	271,734
Supplier E	*		$	265,127

*: Less than 10%

(k) Business combination

The Company accounts for business acquisitions using the acquisition method of accounting and records intangible assets with finite and indefinite useful lives separate from goodwill. Intangible assets are recorded at their fair value based on estimates as at the date of acquisition. Goodwill is recorded as the residual amount of the purchase price less the fair value assigned to the individual assets acquired and liabilities assumed as the date of acquisition.

(l) Goodwill

Goodwill represents the excess of the purchase price of acquired businesses over the estimated fair value assigned to the individual assets acquired and liabilities assumed. The Company performs its annual impairment test at year end and an impairment test between scheduled annual tests if facts and circumstances indicate that it is more likely than not that the fair value of a reporting unit that has goodwill is less than its carrying value. The Company compares the fair value of a reporting unit to its carrying amount to determine if goodwill may be impaired. The Company estimates the fair value of a reporting unit using the discounted cash flow methodology. Significant management judgment is required in the forecasts of future operating results and discount rates that we use in the discounted cash flow method of valuation and in the selection of comparable businesses that we used in the market approach. If the fair value of a reporting unit is less than its carrying value, an impairment loss is recorded to the extent that the fair value of the goodwill is less than its carrying value. Fair values for reporting units are determined based on discounted cash flows, market multiples or appraised values.

During the third and the fourth quarter of 2012, as a result of the effects of weakening market conditions on the Company’s forecasts and a sustained, significant decline in the Company’s market capitalization to a level lower than its net book value, the Company concluded that impairment indicators existed and performed an impairment analysis. Based on the results of the analysis, the estimated fair value of the reporting unit was determined to be lower than the carrying amount. Accordingly, the Company performed the second step of the impairment test to determine the implied fair value of goodwill, which required the Company to allocate the fair value of the reporting unit determined in step one to all of the assets and liabilities, including any unrecognized intangible assets, of the reporting unit. The Company determined the implied fair value of goodwill was zero. As a result, the Company fully impaired all of its goodwill, resulting in an impairment charge of $6.2 million. No goodwill impairment charges were recognized during the years ended December 31, 2011and 2013.

The carrying amount of goodwill included in the wafer and module segment, for the years ended December 31, 2012 and 2013, was as follows:

	At December 31,
	2012			2013
Beginning of the year	$	5,646,522		$	—
Goodwill impairment during the year	(6,160,545		)	—
Foreign exchange effect	514,023			—
Closing balance	$	—		$	—

(m) Intangible Assets

Intangible assets acquired in a business combination and recognized separately from goodwill are initially recorded at their fair value at the acquisition date (which is regarded as their cost). Subsequent to initial recognition, intangible assets with indefinite useful lives that are acquired separately in a business combination are reported at cost less accumulated impairment losses. At the end of each reporting period, the Company reviews the carrying amount of its intangible assets to determine whether there is any indication that they have suffered an impairment loss. If such indication exists, fair value of the asset(s) is estimated in order to determine the extent of an impairment loss (if any). Based on the results of the analysis, the carrying amount of the intangible assets were lower than their fair value and an impairment loss of $3,764,464 was recognized during the year ended December 31, 2012. Intangible assets have been fully impaired as of December 31, 2012.

(n) Property, plant and equipment

Property, plant and equipment are stated at cost less accumulated depreciation. Depreciation is computed on a straight-line basis over the following estimated useful lives:

Buildings		40-50 years
Plant and machinery		10-25 years
Motor vehicles		4-5 years
Office equipment		3-5 years

Construction in progress represents mainly the construction of new facilities in ReneSola Zhejiang, ReneSola Jiangsu, Sichuan ReneSola, Sichuan Ruiyu. Costs incurred in the construction are capitalized and transferred to property, plant and equipment upon completion, at which time depreciation commences.

(o) Assets held-for-sale

Non-current assets and asset disposal groups are classified as held-for-sale if their carrying amount will be recovered principally through a sale transaction rather than through continuing use. This condition is regarded as met only when the sale is highly probable, the assets are available for immediate sale in their present condition and they are expected to qualify for recognition as a completed sale within one year from the date of classification. Non-current assets classified as held for sale are measured at lower of their carrying amount and fair value less costs to sell. In December 2013, the company had signed a Memorandum of Intent to sell power stations in Western China, the assets and liabilities of the subsidiaries has been classified as assets held for sale and liabilities held for sale as of December 31, 2013. This transaction is subject to customary closing conditions and is expected to close in the course of 2014. Based on the Company’s expectation to continue sales activities with the disposal group after the transaction is completed, the disposal group has not been presented as a discontinued operation. The disposal group did not have a material impact on the revenues or net income/(loss) for any of the periods presented.

The company’s assets held for sale are summarized below:

	As December 31,
	2013
Accounts receivable, net of allowances for doubtful accounts	$	9,427,504
Prepaid expenses and other current assets	2,349,030
Deferred tax assets-current	5,325
Property, plant and equipment, net	109,583,265
Prepaid land use right	1,257,974
Other long-term assets	15,293
Total	$	122,638,391

The company’s liabilities held for sale are summarized below:

	As December 31,
	2013
Short-term borrowings	$	2,147,444
Accounts payable	34,296
Other current liabilities	11,436,750
Long-term borrowings	85,815,166
Total	$	99,433,656

(p) Interest capitalization

The Company capitalizes interest costs as part of the costs of constructing certain assets during the period of time required to get the assets ready for their intended use. The Company capitalizes interest to the extent that expenditures to construct an asset have occurred and interest costs have been incurred.

(q) Prepaid land use right

Prepaid land use right represent payments made to obtain land use rights. Prepaid land use right is recognized as an expense on a straight-line basis over the lease period of 40-50 years.

Expenses recognized were $877,168, $1,080,099 and $1,086,685 for the years ended December 31, 2011, 2012 and 2013, respectively.

(r) Impairment of long-lived assets

Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable or that the useful life is shorter than originally estimated. The Company assesses recoverability of the long-lived assets by comparing the carrying amount of the assets to the estimated future undiscounted cash flows expected to result from the use of the assets and their eventual disposition. The Company recognizes an impairment loss in the event the carrying amount exceeds the estimated future undiscounted cash flows attributable to such assets, measured as the difference between the carrying amount of the assets and the fair value of the impaired assets.

The Company determined that assets that were held-for-sale as of December 31, 2011 became fully impaired during the year ended December 31, 2012, when the counterpart to the sales contract for the mono-crystal furnaces reneged on the contractual arrangement. Given the Company’s inability to find another buyer, and its conclusion that the assets are obsolete with little to no scrap value, the carrying value of these assets, $6,437,716, was written down to zero and an impairment charge of $6,437,716 was recognized for the year ended December 31, 2012 (see Note 5).

At the end of September 2013, the Company concluded that its efforts to sufficiently reduce the cost of production, compared to the prevailing market price of polysilicon, were not successful. After conducting a further internal assessment the Company determined that it was no longer feasible to operate the Phase I facility without a loss and that the carrying amount of the asset was not recoverable and accordingly, recognized an impairment charge in its wafer segment. Production at the Phase I facility was permanently discontinued in October 2013. As result, the Company recognized a $194,694,559 impairment charge associated with these long-lived assets for the year ended December 31 2013. The impairment charge was recognized as the amount by which the carrying amount exceeded the fair value of the idled assets. The fair value of the idled assets was estimated based on two market based analyses, including an assessment that general machinery that could be sold in the market, based on second-hand market quotations and the specialized machines and associated facilities have scrap value associated with their metal components, net of dismantling cost, freights, and relevant taxes. (see Note 5).

(s) Deferred convertible notes issuance costs

The issuance costs incurred in connection with the issuance of the Company’s Convertible Senior Notes due 2018 (“Notes”) in the amount of $7,156,101 were deferred and are being amortized on a straight-line basis, which approximates the effective interest rate method, from March 15, 2011, the date of issuance, to March 15, 2016, the earliest redemption date. The amortization, recorded in interest expense, was $784,456 and $784,456 for the year ended December 31, 2012 and 2013, respectively.

(t) Income taxes

Deferred income taxes are recognized for temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements, net operating loss carry forwards and credits by applying enacted statutory tax rates applicable to future years. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Current income taxes are provided for in accordance with the laws of the relevant taxing authorities. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The components of the deferred tax assets and liabilities are individually classified as current and non-current based on the characteristics of the underlying assets and liabilities or the expected timing of their use when they do not relate to a specific asset or liability.

(u) Revenue recognition

The Company sells solar power products including virgin polysilicon, monocrystalline and multicrystalline solar wafers and PV cells and modules. The Company also enters into agreements to process silicon materials into silicon ingots and wafers, and to process PV cells into modules for customers. The Company recognizes revenues when persuasive evidence of an arrangement exists, the products are delivered and title and risk of loss has passed to customers, the price to the buyer is fixed and determinable, and collectability is reasonably assured. Sales agreements typically contain customary product warranties but do not contain any post-shipment obligations nor any return or credit provisions.

A majority of the Company’s contracts provide that products are shipped under free on board (“FOB”) terms, cost, insurance and freight (“CIF”) terms or delivered duty unpaid (“DDU”) terms. Under FOB, the Company fulfills its obligation when the goods have passed over the ship’s rail at the named port of shipment. The customer bears all costs and risks of loss or damage to the goods from that point. Under CIF, the Company must pay the costs, insurance and freight necessary to bring the goods to the named port of destination, and bears the risk of loss or damage to the goods during transit. Under DDU, the Company is responsible for making a safe delivery of goods to a named destination, paying all transportation expenses but not the duty. The Company bears the risks and costs associated with supplying the good to the delivery location. The Company recognizes revenue when the title of goods and risk of loss or damage is transferred to the customers based on the terms of the sales contracts, and if the other recognition criteria are met.

In 2012, the Company commercially began developing and operating solar power projects which have generated electricity in China. Revenue from solar power projects that are held and used is recognized as revenue after the solar power plant is connected to the grid and as it generates electricity.

The Company also has been developing solar projects, referred to as project assets, with the intention to sell such project assets. The Company accounts for the project assets following the provisions of real estate accounting. Under the provisions of real estate accounting, the Company recognizes revenue and the corresponding costs once the sale is consummated, the buyer’s initial and any continuing investments are adequate, the resulting receivables are not subject to subordination and the Company has transferred the customary risk and rewards of ownership to the buyer. The Company has not recognized any revenue from sales of project assets in 2012 and 2013.

(v) Cost of revenues

Cost of revenues consists of production related costs including costs of silicon raw materials, consumables, direct labor, overhead costs, depreciation of plant and equipment, contractor and processing fees and warranty costs. Shipping and handling costs incurred on sale of products and included in sales and marketing expense were $9,058,534, $14,524,853 and $36,678,733 for the years ended December 31, 2011, 2012 and 2013, respectively.

(w) Research and development

Costs related to the design, formulation and testing of new products or process alternatives are included in research and development expenses. Research and development costs are expensed when incurred.

(x) Warranty costs

The Company’s solar modules are typically sold with 25 year warranties against specified declines in the initial minimum power generation capacity at the time of delivery. The Company also provides warranties for solar modules against defects in materials and workmanship for a period of five or ten years from the date of sale. Warranty cost is accrued at the point the related module revenue is recognized. Due to the limited solar module manufacturing history, the Company does not have a significant history of warranty claim. Cost of warranties is estimated based on an assessment of the Company’s and competitors’ accrual history, industry-standard testing, estimates of failure rates from quality review and other assumptions that are considered to be reasonable under the circumstances. Actual warranty costs are accumulated and charged against accrued warranty liability. To the extent that actual warranty cost differs from the estimates, the Company will prospectively revise the accrual rate. As such estimates are subjective, the Company will continue to analyze its claim history and the performance of its products and compare against its competitors, industry data for warranty claims, and other assumptions, such as academic research, to determine whether its accrual is adequate. The Company has adopted a warranty accrual rate of 1.0% of PV module revenues, based on its assessment of industry norms which also represents the Company’s best estimate to date. Should it begin to experience warranty claims differing from its accrual rate, the Company would prospectively revise the warranty accrual rate. The Company revised downward the estimated cost to satisfy the Company’s outstanding product warranty by $7,787,834 for the year ended December 31, 2012, attributable primarily to decreases in the average selling prices (“ASPs”) for solar modules, a primary input into the estimated costs of the Company’s warranty policy.

(y) Government grants

Government grants received by the Company consist of unrestricted grants and subsidies and restricted grants. Depending upon the nature of grant, government grants are recognized as either directly in other operating income or as deferred subsidies first and amortized into the other income.

The Company recorded $4,305,347, $4,287,891 and $4,297,693 government grants for the years ended December 31, 2011, 2012 and 2013 in other operating income, respectively. Government grants related to property, plant and equipment are recorded as deferred subsidies and are amortized on a straight-line basis over the useful life of associated assets. The Company received government grants related to property, plant and equipment and land use right of $7,132,358, $1,458,283 and $16,819,424 during the years ended December 31, 2011, 2012 and 2013, respectively. The deferred government grants as of December 31, 2012 and 2013 were $27,311,528 and $44,150,492, respectively, included in deferred subsidies and other in the consolidated balance sheets. The Company amortized the deferred grants in the amount of $628,133, $808,089 and $988,312 into other operating income for the years ended December 31, 2011, 2012 and 2013, respectively.

(z) Other operating expense (income)

Other operating expense (income) primarily consists of gains or losses on disposal of fixed assets and land use right, subsidies received from the government, and forfeitures of advances from customers.

(aa) Foreign currency

The functional currency of ReneSola Ltd is the United States Dollar (“U.S. dollar”). The functional currency of ReneSola’s subsidiaries in the PRC is Renminbi (“RMB”). The functional currency of ReneSola America, ReneSola Singapore and Renesola Panama is the U.S. dollar, the functional currency of ReneSola Germany, ReneSola New Energy, NOVE and MG is Euro, the functional currency of LUCAS and ECOSFER is Leu, the functional currency of ReneSola Australia is AUD, the functional currency of ReneSola Japan is JPY, the functional currency of ReneSola India is Rupee , the functional currency of Lucas Korea and Ecosfer Korea is Won, the functional currency of Renesola Zagreb is Kuna, the functional currency of ReneSola UK is Pound, the functional currency of Renesola South Africa is ZAR.

Foreign currency transactions have been translated into the functional currency at the exchange rates prevailing on the date of transactions. Foreign currency denominated monetary assets and liabilities are translated into the functional currency at exchange rates prevailing on the balance sheet date. Exchange gains and losses have been included in determination of net income.

The Company has chosen the U.S. dollar as its reporting currency. Assets and liabilities have been translated using exchange rates prevailing on the balance sheet date. Income statement items have been translated using the weighted average exchange rate for the year. Translation adjustments have been reported as a component of other comprehensive income in the statement of comprehensive income.

The RMB is not a freely convertible currency. The PRC State Administration for Foreign Exchange, under the authority of the People’s Bank of China, controls the conversion of RMB into foreign currencies. The value of the RMB is subject to changes in central government policies and to international economic and political developments affecting supply and demand in the China foreign exchange trading system market. The Company’s cash and cash equivalents denominated in RMB amounted to RMB 421,256,247($67,616,261) and RMB 245,149,128 ($40,495,694) at December 31, 2012 and 2013, respectively. And the Company’s restricted cash denominated in RMB amounted to RMB 1,004,827,282($161,285,832) and RMB 1,492,476,591 ($ 246,539,223) at December 31, 2012 and 2013, respectively.

(ab) Fair value of financial instruments

Fair value represents the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (also referred to as an exit price). The Company utilizes a hierarchy for inputs used in measuring fair value that gives the highest priority to observable inputs and the lowest priority to unobservable inputs. Valuation techniques used to measure fair value shall maximize the use of observable inputs.

When available, the Company measures the fair value of financial instruments based on quoted market prices in active markets, valuation techniques that use observable market-based inputs or unobservable inputs that are corroborated by market data. Pricing information the Company obtains from third parties is internally validated for reasonableness prior to use in the consolidated financial statements. When observable market prices are not readily available, the Company generally estimates the fair value using valuation techniques that rely on alternate market data or inputs that are generally less readily observable from objective sources and are estimated based on pertinent information available at the time of the applicable reporting periods. In certain cases, fair values are not subject to precise quantification or verification and may fluctuate as economic and market factors vary and the Company’s evaluation of those factors changes. Although the Company uses its best judgment in estimating the fair value of these financial instruments, there are inherent limitations in any estimation technique. In these cases, a minor change in an assumption could result in a significant change in its estimate of fair value, thereby increasing or decreasing the amounts of the Company’s consolidated assets, liabilities, equity and net income or loss. See Note 6, “Fair Value Measurements”, for further details.

(ac) Derivative financial instruments

The Company uses foreign exchange forward contracts to hedge the foreign currency exchange risk inherent in the future cash flows associated with forecasted sales denominated in foreign currencies, mainly in U.S. Dollar or Euro.

The Company accounts for these forward contracts as derivative instruments and recognizes all derivative instruments as either assets or liabilities at fair value in other financial assets or other financial liabilities in the consolidated balance sheets. The Company does not offset the carrying amounts of derivatives with the same counterparty.

In 2010, the Company began to employ foreign currency cash flow hedge accounting with respect to certain foreign-currency forward exchange contracts that the company entered into to hedge potential changes in the cash flow of forecasted foreign currency denominated sales transactions within the next two years attributable to changes in foreign currency exchange rates. When the designed hedging relationships are highly effective, the effective portion of gain or loss on the designated derivative instruments is recorded in accumulated other comprehensive income, net of tax, until the underlying hedged transaction is recognized in the consolidated income statements. The ineffective portion of cash flow hedges, if any, is recognized in income immediately. The effectiveness of designated hedging relationships is tested and documented on a quarterly basis. In the fourth quarter of 2011, as the hedged sales transactions were determined to no longer be probable of occurrence as the contract was under re-negotiation and would likely be terminated, the cash flow hedge accounting was discontinued and accordingly, the entire balance in accumulated other comprehensive income was reclassified into net gain (loss) on derivative instruments. The net change associated with hedging transaction was ($1,236,306) in the year ended December 31, 2011. No derivative instruments qualified to be accounted for as cash flow hedges during the year ended December 31, 2012 and 2013, respectively.

The loss from change in fair value of derivatives, which qualified for cash flow hedge accounting, reported in accumulated other comprehensive income was $1,236,306, $nil, and $nil, in the years ended December 31, 2011, 2012 and 2013, respectively. Of these amounts, $1,164,711, $nil, and $nil were reclassified into revenue upon realization of the hedged transactions in the end years ended December 31, 2011, 2012 and 2013, respectively. As a result of designed hedging relationship becoming ineffective in the fourth quarter of 2011, the balance of $785,092 recorded in accumulated other comprehensive income was reclassified into net gain (loss) on derivatives.

The Company’s other derivative instruments do not qualify for hedge accounting. Accordingly, gains or losses resulting from changes in the values of those derivative instruments are recognized as (gain) loss on derivatives, net, in the consolidated income statement.

Net (gains) losses on derivative instruments from foreign currency forward exchange contracts were $15,296,530, $53,945 and ($535,451), in the years ended December 31, 2011, 2012 and 2013, respectively. As of December 31, 2013, the Company has outstanding foreign exchange forward contracts with a total notional amount of $232,019,591.

As of December 31, 2012, the Company has $660,463 in current derivative assets, $nil in non-current derivative assets, $975,053 in current derivative liabilities, and $nil in non-current derivative liabilities in total. As of December 31, 2013, the Company has $1,502,578 in current derivative assets, $nil in non-current derivative assets, $ 1,463,252 in current derivative liabilities, and $nil in non-current derivative liabilities in total.

(ad) Earnings (loss) per share

Basic earnings (loss) per share is computed by dividing income attributable to holders of common shares by the weighted average number of common shares outstanding during the year. Diluted earnings (loss) per share reflects the potential dilution that could occur if securities or other contracts to issue common shares were exercised or converted into common shares.

In 2011, the Company issued 40,000 ordinary shares to its share depository bank which will be used to settle stock option awards upon their exercise. No consideration was received by the Company for this issuance of ordinary shares. These ordinary shares are legally issued but are treated as escrowed shares for accounting purposes and therefore, have been excluded from the computation of earnings per share. Any ordinary shares not used in the settlement of stock option awards will be returned to the Company. No additional ordinary shares were issued in 2012.

In 2013, the Company issued 31,000,000 ordinary shares to its share depository bank which will be used to settle stock option awards upon their exercise. Besides this, 1,000,000 ordinary shares are legally issued but are treated as escrowed shares for accounting purposes and therefore, have been excluded from the computation of earnings per share. Any ordinary shares not used in the settlement of stock option awards will be returned to the Company.

(ae) Share-based compensation

The Company recognizes expenses for services received in exchange for awards of equity instruments based on the grant-date fair value of the award as determined by the Black-Scholes option pricing model, net of estimated forfeitures. The estimated compensation cost is recognized ratably over the period the grantee is required to provide services per the conditions of the award. See Note 12, “Share Based Compensation”, for further details.

(af) Comprehensive income (loss)

Comprehensive income is the change in equity during a period from transactions and other events and circumstances from non-shareholder sources. Components of the Company’s comprehensive income include net income, foreign currency translation adjustments. As of December 31, 2012 and 2013, accumulated other comprehensive income was comprised entirely of foreign currency translation adjustments.

(ag) Treasury Stock

On August 20, 2011, the Company’s Board of Directors authorized the Company to repurchase up to $100 million in aggregate value of its outstanding ordinary shares through open market or private transactions during the six months period ending in February, 2012, depending on market condition. On September 6, 2011 and September 9, 2011, the Company repurchased 309,924 and 335,500 ADSs, respectively, on the open market at a price of $3.0614 and $2.9271, respectively, for a total purchase price of $1,943,822. The Company has legal title to the shares, and no other party has the voting rights associated with these shares.

The Company canceled all of the treasury stock on February 29, 2012.

(ah) Concentrations of credit risk

Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents, accounts receivable and advances to suppliers and related parties. The Company places its cash and cash equivalents with financial institutions with high-credit ratings and quality. The Company conducts credit evaluations of customers and generally does not require collateral or other security from its customers. The Company establishes an allowance for doubtful receivables mainly based on the age of receivables and factors surrounding the credit risk of specific customers. The Company performs ongoing credit evaluations of the suppliers’ financial conditions. The Company generally does not require collateral or other security against such suppliers; however, it maintains a reserve for potential credit losses. Such losses have historically been within management’s expectations.

(ai) Recently issued accounting pronouncements

In February 2013, the FASB issued ASU No. 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. ASU 2013-02 requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about those amounts. ASU 2013-02 is effective for fiscal years, and interim periods within those years, beginning on or after December 15, 2012. The Company adopted the new guidance in the first quarter of 2013. The adoption did not have a material impact on the Company’s consolidated financial statements and related disclosure.

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 implementation will not have a material impact on the Company’s consolidated financial statements or related disclosure.

Construction in progress represents new production facilities under construction in ReneSola Zhejiang, ReneSola Jiangsu, Sichuan ReneSola and Sichuan Ruiyu.

The carrying amount of the power stations is $16.8million as of December 31, 2013 and is included in “Buildings” and “Plant and machinery,” and was reclassified from project assets to property plant and equipment at the point it no longer met the held for sale criteria.

Depreciation expense for the years ended December 31, 2011, 2012 and 2013 was $82,730,940, $93,501,714 and $ 112,894,150, respectively.

During the third quarter of 2012, as a result of weak market conditions and a significant decline in the Company’s market capitalization to a level lower than its net book value, the Company concluded that circumstances existed which required the Company to test certain long-lived assets for recoverability. Based on the recoverability tests performed, the Company determined that no impairment was required except for the mono furnaces which had previously been recorded as assets held-for-sale and were determined to be obsolete, after the counterparty reneged on their obligations under the contractual sales agreement. As a result, a total impairment charge of $6,437,716 was recognized.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS

6. FAIR VALUE MEASUREMENTS

The Company adopted ASC 820, “Fair Value Measurements and Disclosures”, which provides a framework for measuring fair value under U.S. GAAP, and expanded disclosure requirements about assets and liabilities measured at fair value. The Company utilizes a hierarchy for inputs used in measuring fair value that gives the highest priority to observable inputs and the lowest priority to unobservable inputs as follows:

· Level 1-Observable unadjusted quoted prices in active markets for identical assets or liabilities.

· Level 2-Observable inputs other than quoted prices in active markets for identical assets or liabilities, for which all significant inputs are observable, either directly or indirectly.

· Level 3-Unobservable inputs to the valuation methodology that are significant to the measurement of fair value of assets or liabilities.

Assets and liabilities carried at fair value as of December 31, 2013 are classified in the categories described above based on the lowest level input that is significant to the fair value measurement in its entirety.

Recurring basis

The following table displays assets and liabilities measured on the Company’s consolidated balance sheet at fair value on a recurring basis subsequent to initial recognition:

	As of December 31, 2013
	Fair Value Measurements at Reporting Date Using
	Total Fair Value and Carrying Value on the Balance Sheet			Quoted Prices in Active Markets for Identical Assets (Level 1)	Significant Other Observable Inputs (Level 2)			Significant Unobservable Inputs (Level 3)

	As of December 31, 2012
	Fair Value Measurements at Reporting Date Using
	Total Fair Value and Carrying Value on the Balance Sheet			Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)			Significant Unobservable Inputs (Level 3)
Cross currency forward exchange contracts -recorded as derivative assets	660,463			—		660,463			—
Cross currency forward exchange contracts -recorded as derivative liabilities	(975,053		)	—		(975,053		)	—
	$	(314,590	)	$	—	$	(314,590	)	$	—

Derivatives-The Company’s use of derivatives primarily consists of foreign currency forward contracts. As quoted prices in active markets for identical assets are not available, the Company uses quotes obtained from professional pricing sources. The Company performs internal validation procedures on quotes from pricing sources using valuation techniques commonly used in the industry, and also considers the credit ratings of respective counterparties in determining the impact of risk of defaults on the valuation of derivative assets. These fair value measurements are classified as level 2.

Warrant liability-The fair value of the warrant liability (see Footnote 11) was determined using the Monte Carlo Model, with certain inputs significant to the valuation methodology classified as level 2.

Cash and cash equivalents, restricted cash, accounts receivable, accounts payable, accounts due to and from related parties, and short-term borrowings are carried at cost on the consolidated balance sheets and the carrying amount approximates their fair value because of the short-term nature of these financial instruments.

The carrying amount of the Company’s outstanding convertible notes as of December 31, 2012 and 2013 was $111.6 million and $111.6 million, respectively. The estimated fair value of those debts was $59.2 million and $77.8 million, respectively, as of December 31, 2012 and 2013. The fair value was measured based on observable market quotes and is therefore considered a level 1 fair value measurement.

The Company’s long-term bank borrowing consists of floating rate loans that are reset annually. The carrying amount of long-term borrowings (including the current portions) was $193.6 million and $113.4 million as of December 31, 2012 and 2013, respectively. The estimated fair value of long-term borrowings (including the current portions) was $184.0 million and $111.2 million as of December 31, 2012 and 2013, respectively. The fair value is measured using discounted cash flow technique based on current rates for comparable loans on the respective valuation date and it therefore considered a level 2 input.

Fair values of non-financial assets measured on a non-recurring basis

During the year ended December 31, 2012 and 2013, the Company recorded certain non-financial assets at fair value following events that required the Company to assess goodwill, intangible assets and long-lived assets for impairment.

	Fair Value as of September 30, 2013 Measured Using Significant Other Observable Inputs (Level 2)		Total Losses for Year Ended December 31, 2013
Long-lived assets - Sichuan Phase I factory	$	6,096,778	$	194,694,559

	Fair Value as of December 31, 2012 Measured Using Significant Unobservable Inputs (Level 3)	Total Losses for Year Ended December 31, 2012
Goodwill	—	$	6,160,545
Intangible asset	—	$	3,764,464
Long-lived assets — mono crystal furnaces	—	$	6,437,716

As of December 31, 2013, long-lived assets held and used with a carrying amount of $200,791,337 were written down to their fair value of $6,096,778, resulting in an impairment charge of $194,694,559. The fair value of assets was estimated using direct comparison method under the market approach. The direct comparison method is a set of procedures in which a value indication is derived by comparing the second-hand market quotations of the similar assets or the average market price of the stainless steel and copper (see Note 2(r)).

As of December 31, 2012, goodwill with a carrying amount of $6,160,545 was written down to $nil, resulting in an impairment charge of $6,160,545which was included in earnings. As of December 31, 2012, Intangible assets with a carrying amount of $3,764,464 were written down to their implied fair value of $nil, resulting in an impairment charge of $3,764,464 which was included in earnings. Long-lived assets of mono-crystal furnaces with a carrying amount of $6,437,716 were written down to their implied fair value of $nil, resulting in an impairment charge of $6,437,716 which was included in earnings for the year ended December 31, 2012 (see Note 2(r)).

ReneSola is not subject to tax under the laws of British Virgin Islands.

ReneSola Zhejiang is a Foreign Invested Enterprise (“FIE”) incorporated in the PRC. The statutory income tax rate in the PRC is 25% starting from 2008.

ReneSola Zhejiang obtained the approval of High-New Technology Enterprise (“HNTE”) status in 2009 and renewed the HNTE status for another 3-year period from 2012 to 2014. ReneSola Jiangsu obtained the approval of HNTE status for the period from 2012 to 2014. Sichuan ReneSola obtained approval of HNTE status for the period from 2012 to 2014. Under the EIT Law, a HNTE is eligible for the 15% reduced EIT rate.

For PRC entities, the qualified research and development expenses incurred by them for development of new technology, new products and new techniques could have a 50% super deduction in addition to the actual expense deductions for PRC enterprise income tax purpose. A number of group entities are eligible for such R&D super deduction.

According to EIT law and its implementation rule, incomes earned from major Stated-supported public infrastructure facility projects are eligible for a 6-year tax holiday, which provides a tax exemption for 3 years from the first year revenue is generated and 50% reduction for the following 3 years. Qinghai Yuhui, Keping, Beijing Xuyuan, Tekesi and Suibin are engaged in such major state-supported public infrastructure facility projects and may be entitled to the aforesaid tax holiday upon the approval from the tax authority. As of December 31, 2013, Qinghai Yuhui and Keping have obtained relevant tax holiday approvals from the tax authority and the tax holiday was effective in 2012 and 2013.

The Group also has overseas operations in the jurisdiction of the United States, Republic of Singapore, Federal Republic of Germany, Republic of Bulgaria, Commonwealth of Australia, Japan, Republic of India, Grand Duchy of Luxembourg,Republic of Romania, United Kingdom, Republic of South Africa, Republic of Croatia, Republic of Panama and Republic of Korea. The corporate income tax rates range from 10% to 35%.

Zhejiang ReneSola, Sichuan ReneSola, Sichuan Ruiyu, Sichuan Ruixin, Sichuan OuRuida, Sichuan SiLiDe, Zhejiang Ruixu, Energy-Saving Technology, Carbon Fiber, Zhejiang Academe, Beijing Xuyuan, Tekesi and Suibin are incorporated in the PRC. The corporate income tax rate is 25%.

During the year ended December 31, 2011, 2012 and 2013, the Company recorded a reversal of unrecognized tax benefits of $1,439,880, $nil and $nil, respectively. The reversal of tax liabilities recorded in 2011 was mainly associated with the release of withholding tax liability associated with capital gains arising from the sale of a Joint Venture. Management subsequently determined such liabilities would not be realized, and as such the withholding tax liability previously recorded was released.

The following is the tabular reconciliation of liabilities for unrecognized tax benefits:

	Years ended December 31,
	2011			2012		2013
Unrecognized tax benefit-Opening balance	$	1,645,182		$	205,302	$	205,302
Release of tax liability	(1,439,880		)	—		—
Unrecognized tax benefit-Closing balance	$	205,302		$	205,302	$	205,302

The Company classifies interest and penalties related to income tax matters in income tax expense. As of December 31, 2011, 2012 and 2013, the amount of interests and penalties related to uncertain tax positions was immaterial. The Company does not anticipate any significant increases or decreases to its liabilities for unrecognized tax benefits within the next twelve 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. The statute of limitations will be extended to five years under special circumstances, which are not clearly defined, but an underpayment of taxes exceeding RMB100,000 (approximately $16,266) is specifically listed as a special circumstance. In the case of a transfer pricing related adjustment, the statute of limitations is ten years. There is no statute of limitations in the case of tax evasion. The Company’s PRC subsidiaries are therefore generally subject to examination by the PRC tax authorities from 2008 through 2013 on non-transfer pricing matters, and from 2002 through 2013 on transfer pricing matters.

The principal components of deferred income tax assets and liabilities are as follows:

	At December 31,

As of December 31, 2013, the PRC Companies had net operating loss carry forwards of $336,371,862, of which $24,757,217, $32,009,954, $217,985,844 and $61,618,847 will expire in 2014, 2016, 2017 and 2018, respectively. ReneSola US had net operating loss carry forwards of $7,257,620, which will expire from 2032 to 2033.

The Company considers positive and negative evidence to determine whether some portion or all of the deferred tax assets will not be realized. This assessment considers, among other matters, the nature, frequency and severity of recent losses, forecasts of future profitability, the duration of statutory carry forward periods, the Company’s experience with tax attributes expiring unused and tax planning alternatives.

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 for tax purposes. As a result, the Company has recognized a valuation allowance of $64,373,317 and $134,888,129 as at December 31, 2012 and 2013, respectively.

Reconciliation between the applicable statutory income tax rate and the Company’s effective tax rate for the years ended December 31, 2011, 2012 and 2013 is as follows:

	Years ended December 31,
	2011		2012		2013
PRC applicable income tax rate	25.0	%	25.0	%	25.0	%

Others	0.9	%	(0.4	)%	0.6	%
Effective income tax rate	107.3	%	(9.7	)%	1.0	%

The aggregate amount and per share effect of the Tax Holiday are as follows:

	Years ended December 31,
	2011		2012			2013
Aggregate	$	5,006,341	$	(12,231,260	)	$	8,943,517
Per share effect -basic	$	0.03	$	(0.07	)	$	0.05
Per share effect-diluted	$	0.03	$	(0.07	)	$	0.05

In accordance with the EIT Law, dividends, which arise from profits of FIEs earned after January 1, 2008, are subject to a 10% withholding income tax. Under applicable accounting principles, a deferred tax liability should be recorded for taxable temporary differences attributable to the excess of financial reporting basis over tax basis in a domestic subsidiary. However, a deferred tax liability is not recognized if the basis difference is not expected to reverse in the foreseeable future and is expected to be permanent in duration. The Company believes that the PRC entities’ undistributed earnings generated after January 1, 2008 will be permanently reinvested in the PRC entities. As such, no deferred taxes have been recorded on these undistributed earnings of the Company’s PRC subsidiaries as these differences are not expected to reverse in the foreseeable future and are expected to be permanent in duration. The temporary difference for which no deferred tax liability has been recognized is $30.8million and $52.3 million as of December 31, 2012 and 2013, respectively. The undistributed earnings accumulated in other overseas operating entities are immaterial.

CONVERTIBLE SENIOR NOTES
CONVERTIBLE SENIOR NOTES	10. CONVERTIBLE SENIOR NOTES On March 15, 2011, the Company issued $175,000,000 of U.S. Dollar-Settled 4.125% Convertible Senior Notes (“Notes”) due March 15, 2018, which are convertible into American Depositary Shares (the “ADSs”) , each currently representing two ordinary shares of the Company. On April 7, 2011, an over-allotment option up to $25,000,000 aggregate principal amount of Notes were fully exercised by initial purchasers. The key terms of the Notes are as follows: Interest. The Notes bear interest at the rate of 4.125% per annum, payable semi-annually in arrears on March 15 and September 15, commencing September15, 2011. Redemption at maturity. Each Note will be redeemable upon maturity at price of 100% of principal amount plus accrued interest, if any, from March 15, 2016. Conversion. The Notes may be converted into ADSs at the option of the holders at any time prior to maturity. The conversion price is initially $10.5473 per ADS and is subject to adjustment upon the occurrence of specified events but will not be adjusted for accrued and unpaid interest, if any. Based on the conversion price of $10.5473 per ADS, the number of ADSs to be allotted and issued by the Company on full conversion of the Notes will be approximately 18,962,269. Put Options. The holders have the option to require the Company to redeem all or any portion of the Notes on March 15, 2016 (the “repurchase date”), at a repurchase price equal to 100% of the principle amount plus any accrued and unpaid interest, if any, to, but excluding the repurchase date. Capped call transaction. In connection with the pricing of the Notes, the Company has entered into a capped call transaction with an affiliate of one of the initial purchasers of the Notes (the “hedge counterparty”). The capped call transaction is expected generally to reduce potential dilution to the Company’s ordinary shares and ADSs upon conversion of the Notes. The cap price under the capped call transaction is $15.0675 per ADS, and the premium of preliminary and over-allotment option is $21,504,779 and $3,197,500, respectively. The premium was first credited to additional paid-in capital, and then to retained earnings once additional paid-in capital was reduced to zero. No beneficial conversion feature charge was recognized for the issuance of the Notes as the estimated fair value of the ordinary shares was less than the conversion price on the date of issuance. The embedded conversion option and put options are not bifurcated and recognized as derivatives. For the year ended December 31, 2011, approximately $88,384,000 par value Notes was repurchased using cash of $57,055,127. The related deferred issuance costs of $2,978,934 were expensed. The Company recorded a net gain of $28,349,939 on the repurchase of the Notes. As a result of the repurchase of these Notes, a portion of the premium paid in connection with the capped call facility of $861,280 was refunded. As of December 31, 2012 and 2013, the carrying value of the Notes was $111,616,000 and $111,616,000, respectively. For the year ended December 31, 2011, the Company paid issuance costs of $7,156,101, which are being amortized from the date of issuance, to the redemption date, using the straight-line method, which approximates the effective interest rate method. The amortization expense was $784,456 and $784,456 for the year ended December 31, 2012 and 2013, respectively.

WARRANT LIBILITY

WARRANT LIBILITY

11. WARRANT LIBILITY

In connection with the public offering of the Company’s common stock that closed on September 16, 2013, the Company issued to its underwriters, a warrant to purchase up to a total of 10,500,000 shares of common stock (35% of the shares sold in the public offering) at $6.04 per ADS (aggregate of 5,250,000 ADSs) or $3.02 per share. The option is exercisable from September 16, 2013 to September 16, 2017. There are three ways in which the Company might settle the warrant liability: i) physical delivery of Shares, iii) physical delivery of ADS (at the election of the holder) or iii) net share settlement, if unable to register the shares in the case of i and ii. Warrants are separately transferable, and the holder can choose to exercise the warrant in whole or part. The exercise price is subject to adjustment under several circumstances and also to anti-dilution adjustments. All the warrants are outstanding as of December 31, 2013.

The Company is accounting for the warrant as a derivative liability because the exercise price is subject to adjustment under several special circumstances, including anti-dilution clauses. As a result, the warrant is not considered indexed to the Company’s own stock, and as such, all future changes in the fair value of the option are recognized currently in earnings until such time as the warrant is exercised or expired.

This warrant does not trade in an active securities market, and as such, the Company estimates its fair value using the Monte Carlo Simulation as of the date that the warrant was originally issued and as of December 31, 2013 using the following main assumptions:

	As December 31,
	2013
Stock price	$	3.45
Exercise price	$	6.04
Annual dividend yield	—		%
Time to maturity	3.7
Risk-free interest rate	1.11		%
Expected volatility	85.6		%

Expected volatility is based on historical volatility. Historical volatility is computed using daily pricing observations for recent periods that correspond to the term of the warrant. The Company believes this method produces an estimate that is representative of future volatility over the expected term of this warrant. The expected life is based on the remaining term of the warrant . The risk-free interest rate is based on U.S. Treasury securities with time to maturity close to the remaining term of the warrant.

On September 16, 2013, the issue date of the warrant, the Company classified the fair value of this warrant as a liability resulting in a decrease of shareholder’s equity $12,547,500 and the establishment of a $12,547,500 in liability to recognize the warrant’s fair value. The Company recognized a gain of $3,202,500, from the change in fair value of the warrant liability for year ended December 31, 2013.

The following is a reconciliation of the beginning and ending balances of warrants liability measured at fair value on a recurring basis using Level 2 inputs:

	As December 31,
	2013
Beginning balance	$	—
Warrants issued	12,547,500
Fair value change of the issued warrants included in earnings	(3,202,500		)
Ending balance	$	9,345,000

As of December 31, 2013, the warrant to purchase 10,500,000 shares of common stock had not been exercised.

Following is a summary of the warrants activity:

	Number	Weighted Average Exercise Price		Weighted Average Remaining Contractual Life
Outstanding as of December 31, 2012	—	$	—	—

The fair value of the 10,500,000 shares underlying the warrant outstanding as of December 31, 2013 was determined using the Monte Carlo Simulation, see Footnote 6.

Share Awards to Employees

In November 2006, the Company entered into an agreement with Mr. Panjian Li (“Mr. Li”), Chief Executive Officer of ReneSola America, and with Binghua Huang (“Mr. Huang”), Chief Technology Officer of the Company, to grant 40,000 and 20,000 common shares, respectively, each year for a period of five and three years, respectively, commencing January 2008. The fair value of the shares was $4.47 per share based on the market price as of the grant date. These shares do not have an exercise price and vest at no cost to Mr. Li or Mr. Huang.

2007 Share Incentive Plan

On September 27, 2007, the Company adopted the ReneSola Ltd 2007 Share Incentive Plan (the “Plan”) that provides for grant of share options, restricted shares and restricted share units to employees in the Plan. A maximum of 7,500,000 authorized but unissued shares of the Company have been reserved and allocated to the Plan, whose shares were subsequently registered and are issuable upon exercise of outstanding options granted under the Plan. The Plan shall be administered by the Compensation Committee of the Board of Directors (the “Committee”).

Except as otherwise noted in the award agreements with the employee or consultant, the options can be exercised within six years from the award date, except for participant’s termination of employment or service. The vesting schedule and the exercise price per share will be determined by the Committee and set forth in the individual award agreement. In the event of any distribution, share split, or recapitalization of the Company, the Committee shall make such proportionate and equitable adjustments, if any, to reflect such change with respect to (a) the aggregate number and type of shares that may be issued under the Plan and (b) the terms and conditions of any outstanding awards. Except as may otherwise be provided in any award agreement, if a change of control occurs and a participant’s awards are not converted, assumed, or replaced by a successor, such awards shall become fully exercisable and all forfeiture restrictions on such awards shall lapse.

Options to Employees

From January to December 2012, the Company granted 1,700,000 share options to certain employees with exercise prices of $0.74 to $1.35. From January to December 2013, the Company granted 800,000 share options to certain employees with exercise prices of $0.74 to $0.90.

Options Modification

On August 8, 2012, the Board of Directors approved an option modification to reduce the exercise price of all the options granted before August 8, 2012 to the then fair market value of the Company’s ordinary shares underlying such options. All other terms of the share options granted remain unchanged. The modification resulted in incremental compensation cost of $738,363, of which $75,838 was recorded during the year ended December 31, 2013. The remaining $218,152 will be amortized over the remaining vesting period of the modified options, ranging from 2014 to 2017.

The fair value of each option grant, as well as the fair value of option immediately before and after the aforementioned modification, is estimated on the date of grant or modification using the Black-Scholes option pricing model using the assumptions noted below.

	Average risk-free rate of return	Weighted average expected option life	Volatility rate	Dividend yield
Granted in 2011	0.81-2.20%	4.5 years	60.02-82.78%	0%
Granted in 2012	0.68-1.19%	4.5 years	83.47-98.18%	0%
Granted in 2013	0.65-0.80%	4.5 years	175.69-200.98%	0%

Expected volatilities based on the average of the standard deviation of the daily stock prices of the Company and other selected comparable companies in the same industry. The expected term of options represents the period of time that options granted are expected to be outstanding. The risk-free rate of return is based on the US Treasury bond yield curve in effect at the time of grant for periods corresponding with the expected term of the option.

A summary of the option activity is as follows:

	Number of Options		Weighted Average Exercise Prices	Weighted Average Remaining Contractual Life	Aggregate Intrinsic Value
Options
Outstanding on January 1, 2013	7,856,600		0.74	2.51	263,081

Exercisable at December 31, 2013	3,431,800		0.74	1.12	3,392,582

The weighted average fair value of options granted during the years ended December 31, 2011, 2012 and 2013 was $0.94, $0.58 and $0.81, respectively.

Total intrinsic value of options exercised for the years ended December 31, 2011, 2012 and 2013 was $104,671, $nil and $544,888, respectively.

Compensation cost of $4,359,540, $2,221,406 and $1,626,560 has been charged against income during the year ended December 31, 2011, 2012 and 2013, respectively. As of December 31, 2013, there was $ 3,236,091 in total unrecognized compensation expense related to unvested share-based compensation arrangements granted under the Plan, which is expected to be recognized over a weighted-average period of 3.01 years.

Wholly-owned PRC subsidiaries are not required to make appropriations to the enterprise expansion reserve but appropriations to the general reserve are required to be made at not less than 10% of the profit after tax as determined under PRC GAAP. The staff welfare and bonus reserve is determined by the board of directors. The general reserve is used to offset future extraordinary losses. The subsidiary may, upon a resolution passed by the shareholder, convert the general reserve into capital. The staff welfare and bonus reserve is used for the collective welfare of the employees. The enterprise expansion reserve is for the expansion of ReneSola Zhejiang’s operations and can be converted to capital subject to approval by the relevant authorities. These reserves represent appropriations of the retained earnings determined in accordance with the Chinese law. In addition to the general reserve, the Company’s PRC subsidiaries are required to obtain approval from the local PRC government prior to distributing any registered share capital. Accordingly, both the appropriations to general reserve and the registered share capital of the Company’s PRC subsidiaries are considered as restricted net assets amounting to$586,461,209 and $757,771,236 as of December 31, 2012 and 2013, respectively.

COMMITMENTS AND CONTINGENCIES

COMMITMENTS AND CONTINGENCIES

18. COMMITMENTS AND CONTINGENCIES

a) Capital commitment

As of December 31, 2013, the Company had commitments outstanding to purchase property, plant and equipment for $16,513,393, of which $16,291,575, $133,252 and $88,566 are due in 2014, 2015 and 2018, respectively.

b) Purchase commitments

In order to secure future silicon materials, the Company has entered into several long-term supply agreements with overseas suppliers in 2010. Under such agreements, the suppliers agreed to provide the Company with specified quantities of silicon materials, and the Company has made prepayments to these suppliers in accordance with the supply contracts.

Under the terms of certain supply agreements, the company is required to purchase polysilicon of $ 106,650,948 in total over the next 2 years, at prevailing market prices at the time of purchase. The quantities of raw materials governed by these contracts represent amounts the Company will utilize in the normal course of operations.

c) Product warranties

The Company offers warranties on its products and record an estimate of the associated liabilities. Product warranty activity during the years ended December 31, 2012 and 2013 was as follows:

	At December 31,
	2012		2013
	$		$
Beginning balance	12,835,583		10,316,650
Warranty provision	5,344,853		9,842,133
Revision of warranty costs	(7,787,834	)	—
Warranty cost incurred	(174,334	)	(49,180	)
Foreign exchange effect	98,382		502,690
Ending balance	10,316,650		20,612,293

The Company revised downward the estimated cost to satisfy the Company’s outstanding product warranty by $7,787,834 for the year ended December 31, 2012, attributable primarily to decreases in the ASPs for solar modules, a primary input into the estimated costs of the Company’s warranty policy.

d) Legal matters

The Company is a party to legal matters and claims in the normal course of its operations. While the Company believes that the ultimate outcome of these matters will not have a material adverse effect on our financial position, results of operations or cash flows, the outcome of these matters is not determinable with certainty and negative outcomes may adversely affect the Company.

In June 2011, CEP Ltd., or CEP, one of our module customers, sued us in the High Court in Hong Kong for damages for alleged breach of a sales contract. We denied CEP’s assertion and defended that the termination of the sales contract was due to CEP’s material breach of the sales contract by failure to provide a letter of credit in accordance with the sales contract. The trial is completed and closed in December, 2013, and we’re waiting for the court judgment. Based on the information available to us, a negative outcome is not very probable and the amount of loss, if any, is not reasonably estimable and as such no amount was accrued as of December 31, 2013.

In December 2012, the Company received an unfavorable verdict from the Nanjing Supreme People’s Court in Nanjing, Jiangsu Province in its litigation with one of our module customers, Nanjing Zhongdian New Energy Ltd, for material breach of the sales contract. As a result of this ruling, the Company recorded charges to other operating expense and an accrual for litigation of $1,941,310 in the year ended December 31, 2012. In February 2013, the Company paid the amount in full.

In November 2013, Jiangsu Shuangliang Boiler Co., Ltd., or Jiangsu Shuangliang, one of our suppliers of polysilicon equipment, filed a case with Shanghai International Economic and Trade Arbitration Commission, against Sichuan ReneSola. The arbitration involved a payment for deoxidization furnaces we bought from Jiangsu Shuangliang of approximately RMB55.7 million ($9.2 million), and a penalty of approximately RMB6.7 million ($1.1 million); and Sichuan ReneSola then filed a case to counterclaim against Jiangsu Shuangliang for the compensation of approximately RMB31.6 million ($5.2 million) in relation to the water leaking problems arising with the deoxidization furnaces Jiangsu Shuangliang sold to us. The two disputes are still under arbitration process. Because the lawsuit was recently filed, it is difficult at this time to fully evaluate the claims and determine the likelihood of an unfavorable outcome or provide an estimate of the amount of any potential loss, and as such no amount about the penalty loss was accrued as of December 31, 2013.

SEGMENT REPORTING

19. SEGMENT REPORTING

The Company operates in two principal reportable business segments: Wafer and Cell and module. The Wafer segment involves the manufacture and sales of monocrystalline and multicrystalline solar wafers and processing services. The Cell and module segment involves manufacture and sale of PV cells and modules. Ancillary revenues and expenses, generated from one solar power plant and other unallocated costs and expenses are recorded in Other beginning in 2012. The transactions between reportable segments relate to supplier contracts for the sales of wafers and modules. These transactions are executed based on the stated contract prices, with similar terms and conditions as sales to third parties.

The chief operating decision maker is the chief executive officer of the Company.

The Company only reports the segment information of net sales and gross profit, to conform to the information the chief operating decision maker receives to assess the financial performance and allocate resources. There are no differences between the measurements of the Company’s reportable segment’s gross profit and the Company’s consolidated gross profit, as the Company uses the same profit measurement for all of the reportable segments and the consolidated entity. Furthermore, the Company’s chief operating decision maker is not provided with asset information by segment. As such, no asset information by segment is presented.

The following table summarizes the Company’s revenues generated from each segment:

SUBSEQUENT EVENTS	Dec. 31, 2013
SUBSEQUENT EVENTS
SUBSEQUENT EVENTS	20. SUBSEQUENT EVENTS Subsequent to December 31, 2013, the Company successfully rolled-over $200 million short-term borrowings and obtained new financings totaling $34.6 million, which are comprised of $26.9 million short-term borrowings, for its working capital needs, and $7.7 million long-term borrowings, for its project development. On December 30, 2013, the Company signed a Memorandum of Intent to sell three power station projects in Western China, with a total capacity of 60MW, to Jiangsu Akcome Solar Science & Technology Co., Ltd., pursuant to which the share transfer agreement was subsequently entered into on January 3, 2014. On March 25, 2014, we received a letter from the U.S. Department of Commerce (“USDOC”) in which we were named as one of the mandatory respondents related to an anti-dumping investigation. We intend to fully cooperate with the investigation proceedings and to pursue the best outcome for us, as well as the industry. It is estimated the USDOC will make a preliminary ruling in June 2014. If the USDOC finds sharply increased Chinese shipments to the United States from March 2014 to the preliminary ruling date, this investigation may result in certain retroactive tariffs being applied on products shipped to the United States within the investigation scope, including modules with Chinese and Taiwanese cell elements. We cannot predict the outcome of these proceedings at this time.
