Description of Business and Basis of Presentation	1. Description of Business and Basis of Presentation Description of Business Solar Power, Inc. (“SPI”) and its subsidiaries (collectively the “Company”) is a provider of photovoltaic (“PV”) solutions for business, residential, government and utility customers and investors. The Company provides a full spectrum of engineering, procurement and construction services (“EPC”) to third party project developers, as well as develop, own and operate solar PV projects that sell electricity to the grid in multiple countries, including China, the U.S., the U.K., Panama, Greece, Japan and Italy. Prior to 2014, the Company was primarily engaged in providing EPC services to developers in the U.S. Since 2014, the Company commenced its global project development business by ramping up its portfolio of global solar projects, including projects that the Company intends to hold in the long term and derive electricity generation revenue. As of June 30, 2015, SPI’s major subsidiaries include Xinwei Solar Engineering and Construction (Suzhou) Co., Ltd. (“Xinwei Suzhou”), Xinyu Xinwei New Energy Co., Ltd. (“Xinyu Xinwei”), Sinsin Renewable Investment Limited (“Sinsin”), Gonghe County Xinte Photovoltaic Co., Ltd. (“Xinte”), CECEP Solar Energy (Luxembourg) Private Limited Company (S.a.r.l.), and Italsolar S.r.l, (collectively the “CECEP”), Solar Juice Pty Ltd (“Solar Juice”), SPI Energiebau Renewables GmbH (“SPI Energiebau”), SPI Energy Co., Ltd. (“SPI Energy”), Solarbao E-commerce (HK) Limited (“Solarbao E-commerce”), Jiangsu Solarbao Leasing Co., Ltd. (“Jiangsu Solarbao”), Yanhua Network Technology (Shanghai) Co., Ltd. (“Yanhua Network”), SPI Solar Japan G.K. and Solar Power Inc UK Service Limited. CECEP and Solar Juice were acquired by the Company in February and May 2015 respectively. CECEP owned and operated a number of PV plants in Italy. Solar Juice was engaged in the distribution of PV related products including solar panels in Australia. Refer to Note 4 for details of these acquisitions. SPI Energy was incorporated by SPI as a wholly-owned subsidiary in the Cayman Islands in May 4, 2015. On May 11, 2015, SPI Energy filed a registration statement on Form F-4 in connection with seeking shareholder consent for the approval of a certain agreement and plan of reorganization and related redomicile of SPI to the Cayman Islands. Solarbao E-commerce, Jiangsu Solarbao and Yanhua Network were incorporated by the Company in 2015 for raising funds from individual investors and leasing of solar panels through an online platform owned by Solar Energy E-Commerce (Shanghai) Limited (“Solar Energy”). Solar Energy was incorporated in China on December 8, 2014 by Xiaofeng Peng (“Mr. Peng”), Min Xiahou and Jing Liu, who are the chairman of the Company’s board of directors, deputy chairman of the Company’s board of directors and chief financial controller of the Company respectively. Solar Energy operates the “www.solarbao.com” e-commerce and investment platform which primarily targets retail customers residing in the PRC. On March 26, 2015, the Company, through Yanhua Network, entered into a series of contractual arrangements (“VIE Agreements”) with Solar Energy and its shareholders. The contractual arrangements include power of attorney, call option agreement, equity pledge agreement, and a consulting services agreement. As of the date of these condensed consolidated financial statements, the Company has not established the legal enforceability of these contractual agreements described above including the registration of the equity pledge agreement in the relevant government bureau in the PRC. Therefore, the financial results of Solar Energy could not be consolidated by the Company before the legal enforceability of the contractual agreements is established. Through the on-line platform of Solar Energy, the Company has raised funds from individual investors, who need to register as a member on the platform, through certain on-line products launched by the Company since January 2015. Each on-line products launched on the platform are set with a targeted amount of funds in renminbi to be raised for that product, which is divided into units (“Investment Unit”) with unit value ranging from RMB16.7 to RMB2,500. Individual investors may subscribe for Investment Unit of these on-line products which are generally structured in the way of using the funds from individual investors to purchase solar module or PV related products (“Underlying PV Products”) for leasing to the PV project developers on PV project basis over a specified period. These PV projects may represent the Company’s self developed projects or third party developed projects. Investments made into each on-line product are subject to lock-up period, which ranges from 0-1,080 days, depending on the terms of each on-line product. During the lock-up period, the individual investors could not transfer or redeem their subscribed Investment Units. Anytime after the lock-up period, individual investors are permitted either to transfer their investments in respect of the principal portion to other investors through the on-line platform or request the Company to redeem their subscribed Investments Units. Any Investments Units so redeemed by the Company could be put on the on-line platform for re-sale to other investors. Once Investment Units are subscribed and funds are provided, individual investors are guaranteed by the Company with an minimum investment return for their investments, which ranges from an annual rate of 5.25% to 11.9% for the six-month period ended June 30, 2015, and are guaranteed by the Company in respect of the repayment of funds principal at the end of the investment period. Any funds provided by individual investors without subscribing for any on-line products are not entitled to any interest. For each investments into these On-line products by the individual investors, although a tri-party lease agreement is signed among the individual investors, the Company and the PV project developer with individual investors as legal lessor and the PV project developers as legal lessee, the Company is considered as the accounting lessor in substance because 1) the lease terms, rate of return on the investment funds from individual investors, the initial purchase price and the lease rental of the Underlying PV products payable by the PV developers and the purchase contract of the Underlying PV Products entered with manufacturer are negotiated and concluded by the Company without any involvement by the individual investors; and 2) individual investors are entitled to a minimum interest rate as return that are guaranteed by the Company in respect of their funds provided and does not take credit risk in respect of any default payment by the lessee nor risk of claim on the leased assets; 3) the Company is subject to the credit risk as a principal of the lease transaction and has unconditional commitment to return the funds to the individual investors and assume the title of the leased asset after the lock-up period. Based on the above, the individual investors purely provided funds (as lender) to finance the Company (as borrower) for its purchases of the Underlying PV Products for leasing to a solar PV developer in return for a fixed return. In this regard, lease accounting is adopted with the Company as lessor and third party PV developer as lessee for any Underlying PV Products purchased by the Company for leasing to third party project developers. For those on-line products of which the PV project developer (i.e the legal lessee) is one of SPI’s subsidiaries, the related leasing transactions are eliminated in the condensed consolidated financial statements. Regardless as to whether a SPI’s subsidiaries or a third party PV developer is deemed to be the accounting lessor, all interest bearing funds provided by individual investors are recorded on the condensed consolidated balance sheet as either short term borrowings or long term borrowings included in other noncurrent liability. Funds provided with the lock-up period over one year are classified as long term borrowings and funds with a lock-up period of less than one year are classified as short-term borrowings. Funds that are provided without any on-line products subscribed are non-interest bearing and are reclassified as amount due to individual investors under other current liabilities (See Note 14-Other liabilities). During the six-month period ended June 30, 2015, substantially all of the on-line products launched through the on-line platform are related to the Company self-owned PV projects with SPI’s subsidiaries being the lessee. For those on-line products of which the lessee is third party developer, such leases are classified as finance lease in the Company’s condensed consolidated financial statements. In connection with the launch of the above financing and leasing products, the Company issued to certain third party vendors, Jiangxi LDK Solar Hi-Tech Co., Ltd. (“LDK Jiangxi”) and Suzhou Liuxin Industry Ltd. (“Liuxin”) coupons with total face value of $3,828, $779 and $582 respectively during the six-month period ended June 30, 2015. Both LDK Jiangxi and Liuxin are related parties of the Company. These coupons are freely transferable between holders but could not be redeemed in cash. Each coupon has an expiry date for redemption. Prior to the expiry date, when the holder subscribe the on-line products through the on-line platform owned by Solar Energy described above, the holders could redeem the coupons and reduce the original purchase price for the on-line products by the face value of the coupons. For the coupons issued to the third party vendors and LDK Jiangxi, the Company is entitled to the face value in cash or, if mutually agreed between the Company and LDK Jiangxi or between the Company and the relevant third party vendor, to apply the face value as of offset to outstanding accounts payables to these counterparties. Accordingly, the face values of these coupons, totaling $4,607, were recorded as other receivables upon issuance of the coupons. During the six-month period ended June 30, 2015, other receivable balances related to such coupons totaling $219 and $779 were setoff against the related accounts payable balances when mutual agreement with the counterparties had been reached and the legal right to setoff had been established. As of June 30, 2015, other receivable balances due from third party vendors arising from the coupons amounted to $3,609. The coupons issued to Liuxin were for promotional purposes and Liuxin was not required to pay for the coupons. Accordingly, the Company recorded selling expenses of $582 and nil in the condensed consolidated statement of operation for the six-month and three-month periods ended June 30, 2015 respectively. The face values of the coupons are recorded in other payables upon issuance which were reclassified as the Company’s borrowings when the coupons are redeemed through the purchase of on-line products. As of June 30, 2015, all coupons issued to these counterparties had been redeemed. In order to promote the above on-line products on the platform, the Company offered, from time to time, discount from 5% to 20% on the unit value for Investment Units subscribed by individual investors. The discount offered for on-line products subscribed by individual investors is amortized as interest expense using the effective interest rate method through the end of the lock-up period, which is the earliest date that the Company could be required to repay the unit value in respect of the investment made by individual investors. The Company has also started a series of promotion activities targeting on new member (i.e new individual investors). In 2015, the Company launched the first series of such promotion program pursuant to which any new member registered on-line during the promotion period could be paid back in 3 days with RMB17.26 by paying RMB1 into their newly opened account maintained with the Company. By participating in this program, these new members are not obliged to subscribe for any on-line products at that time or in the future in order to get the amount of RMB17.26 in 3 days. The difference between the amount paid by new members and the amount to be paid back by the Company under this promotion activity is recorded as selling expenses as incurred, which amounted to $1,291 during the six-month and three-month periods ended June 30, 2015. Through its on-line platform, Solar Energy serves as a service agent of the Company to collect funds from and repay funds to individual investors. For the funds collected and repaid through Solar Energy, the Company makes settlement with Solar Energy on a regular basis, which normally does not exceed two-weeks. From June 17, 2015 onwards, the Company has made repayment of borrowings to individual investors directly while Solar Energy still continues to collect the funds from individual investors and settle with the Company within 2 weeks. For the service provided through the on-line platform, Solar Energy generally charges the Company commission fee at 1% of the fund principal invested into the on-line products by individual investors (see Note 22— Related Party Transactions) except for those resale of redeemed on-line products by the Company where no commission will be charged to the Company. Such commission fees were expensed as interest expenses as incurred on the condensed consolidated statement of operation. During the six-month period ended June 30, 2015, the total fund raised from individual investors through Solar Energy amounted to $45,806, of which $5,189 was settled by the coupon issued by the Company to the third party vendors and two related parties without cash inflow as described above and $28,782 had been received by the Company from Solar Energy as of June 30, 2015. The Company recorded the remaining funds to be received from Solar Energy in other receivable- due from related party on the condensed consolidated balance sheet as at June 30, 2015, after the reduction of its commission fee of $133 (See Note 22—Related Party Transactions ) . Basis of Presentation The condensed consolidated financial statements are unaudited and have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) for interim financial information. They should be read in conjunction with the financial statements and related notes to the financial statements of Solar Power, Inc. for the years ended December 31, 2014 and 2013 appearing in Solar Power, Inc.’s Form 10-K filed with the Securities and Exchange Commission (“SEC”) on March 31, 2015. The Company’s June 30, 2015 and 2014 unaudited interim condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the SEC for smaller reporting companies and include the accounts of Solar Power, Inc. and its subsidiaries. Certain information and note disclosures normally included in the annual financial statements on Form 10-K have been condensed or omitted pursuant to those rules and regulations, although the Company’s management believes the disclosures made are adequate to make the information presented not misleading. In the opinion of management, all adjustments, consisting of normal recurring adjustments and reclassifications, necessary to present fairly the Company’s consolidated financial position, results of operations and cash flows for all periods presented have been reflected herein. The Company’s financial position, operating results, cash flows and trends in these unaudited condensed consolidated financial statements are not necessarily indicative of future results that may be expected for any other interim period or for the full year. The preparation of unaudited interim condensed consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the unaudited interim consolidated financial statements as well as the reported amounts of revenues and expenses during the reporting period. Significant accounting estimates used in the preparation of the Company’s consolidated condensed financial statements include: allowance made for doubtful accounts receivable, inventory write-downs, the estimated useful lives of long-lived assets, the impairment of goodwill, long-lived assets and project assets, fair value of derivative liability, valuation allowance of deferred income tax assets, accrued warranty expenses, the grant-date fair value of share-based compensation awards and related forfeiture rates, and fair value of financial instruments. Actual results could differ from those estimates upon subsequent resolution of identified matters. The unaudited interim condensed 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.

Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606), to clarify the principles of recognizing revenue and create common revenue recognition guidance between U.S. GAAP and International Financial Reporting Standards. An entity has the option to apply the provisions of ASU 2014-09 either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying this standard recognized at the date of initial application. ASU 2014-09 is effective for fiscal years and interim periods within those years beginning after December 15, 2017, and early adoption is permitted for periods beginning after December 15, 2016. The Company has not determined which transition method it will adopt, and is currently evaluating the impact of this standard on its consolidated financial statements. In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements — Going Concern (Subtopic 205- 40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, which requires management to evaluate, at each annual and interim reporting period, whether there are conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date the financial statements are issued and to provide related disclosures. ASU 2014-15 is effective for the Company for the fiscal year ending December 31, 2016 and for interim periods thereafter. The Company is currently evaluating the impact of this standard on its consolidated financial statements. In January 2015, the FASB issued ASU No. 2015-01, Income Statement — Extraordinary and Unusual Items (Subtopic 225- 20), which eliminates the concept of reporting for extraordinary items. ASU 2015-01 is effective for the Company for fiscal years, and interim periods within those fiscal years, beginning on January 1, 2016. The Company is currently evaluating the impact of this standard on the Company’s consolidated financial statements. On February 18, 2015, the FASB issued ASU No. 2015-02, Consolidation, which reduces the number of consolidation models and simplifies the current standard. Entities may no longer need to consolidate a legal entity in certain circumstances based solely on its fee arrangements when certain criteria are met. ASU 2015-02 reduces the frequency of the application of related-party guidance when determining a controlling financial interest in a variable interest entity. ASU 2015-02 is effective for the Company’s fiscal year ending December 31, 2016. The Company is currently evaluating the impact of this standard on the Company’s consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-03, Interest — Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. ASU 2015-03 is effective for the Company on a retrospective basis on January 1, 2016. Early adoption is permitted, but only for debt issuance costs that have not been reported in financial statements previously issued or available for issuance. The Company is currently evaluating the impact of this standard on the Company’s consolidated financial statements.

Business Combinations [Abstract]
Business Combinations	4. Business combinations (a) Acquisition of CECEP On January 15, 2015, SPI and SPI China (HK) Limited, a wholly-owned subsidiary of SPI, entered into a stock purchase agreement (the “Stock Purchase Agreement”) with CECEP Solar Energy Hong Kong Co., Limited (“CECEP HK”). Pursuant to the Stock Purchase Agreement, SPI China (HK) Limited agreed to purchase from CECEP HK 100% of issued and outstanding shares of capital stock of CECEP owned by CECEP HK. Through its respective wholly and non-wholly owned subsidiaries in Italy, CECEP are engaged in the development, acquisition, management, and operation of energy projects and facilities dedicated to the production of alternative energy sources and the facilitation of the distribution, supply and sale of such alternative energy power, through four photovoltaic plants with a total capacity of 4.3 MW in Italy. The purchase consideration of CECEP consists of cash and SPI’s common stock. In addition to the purchase considerations, the Company is also required to settle the borrowings in the amount of Euro 7,870 ($8,967) due to CECEP HK on behalf of CECEP (“Payable Settlement”). Including the Payable Settlement, the Company needed to settle cash of Euro 3,125 ($3,561) (“Cash Settlement”) and 5,722,977 shares of SPI’s common stock. The Cash Settlement was fully settled in the form of several installments in March and April 2015. The Stock Consideration was settled on January 30, 2015 by the Company, and the common stock was subject to a three-month lockup period as agreed in the Stock Purchase Agreement. The acquisition was consummated on February 16, 2015 upon completion of all closing conditions. All cash consideration has been settled according to the predetermined payment schedule. The Company issued 5,722,977 shares of its Common Stock to CECEP HK on January 30, 2015. The fair value of the Stock Consideration was determined to be $8,269, which was based on the closing market price of SPI’s common stock on the acquisition date of February 16, 2015, with adjustments for the lockup period and other factors. The acquisition has been accounted for under ASC 805 Business Combinations. The Company made estimates and judgments in determining the fair value of acquired assets and liabilities, based on management’s experiences with similar assets and liabilities with the assistance from an independent valuation firm. The allocation of the purchase price is as follows: USD Identifiable assets acquired and liabilities assumed Cash and cash equivalents 1,389 Accounts receivable 394 Other receivable 1,137 Property, plant and equipment 11,041 Deferred tax asset 180 Accounts payable (244 ) Income tax payable (130 ) Other accrued liabilities (1,234 ) Loans payable (884 ) Identifiable net assets acquired (a) 11,649 Consideration and Payment Settlement (b) 11,830 Non-controlling interests (c) 1,236 Goodwill (b+c- a) 1,417 During the period from the acquisition date to June 30, 2015, CECEP contributed revenue of $615 and earnings of $36 to the Company’s consolidated results. Goodwill primarily represents the expected synergies from combining operations of the Company and CECEP, which are complementary to each other, and any other intangible benefits that would accrue to the Company that do not qualify for separate recognition. (b) Acquisition of Solar Juice On March 31, 2015, SPI China (HK) Limited, a wholly-owned subsidiary of SPI, entered into a share purchase agreement (“Purchase Agreement”) with Andrew Burgess, a citizen of Australia as trustee on the terms of the Burgess Absolutely Entitled Trust, Rami Fedda, a citizen of Australia as trustee on the terms of the Fedda Absolutely Entitled Trust, and Allied Energy Holding Pte Ltd, a company incorporated in Singapore and associated with Simon Tan, a citizen of Singapore (collectively, the “Solar Juice Sellers”). Pursuant to the Purchase Agreement, SPI China (HK) Limited agreed to acquire from Solar Juice Sellers 80% of equity interest in Solar Juice Pty Ltd (“Solar Juice”), an Australian proprietary company. The acquisition was consummated on May 28, 2015 upon completion of all closing conditions. Solar Juice is engaged in the distribution of solar photovoltaic panels, solar inverters and other energy efficient solutions, both domestically and internationally. The purchase consideration consisted of 14,073,354 shares of the Company’s common stock (“Consideration”). The fair value of the Consideration was determined to be $15,578, which was based on the closing market price of the Company’s common stock on the acquisition date of May 28, 2015, with adjustment for the lockup period and other factors. The acquisition has been accounted for under ASC 805 Business Combinations. The Company made estimates and judgments in determining the fair value of acquired assets and liabilities, based on management’s experiences with similar assets and liabilities with the assistance from an independent valuation firm. The allocation of the purchase price is as follows: USD Identifiable assets acquired and liabilities assumed Cash and cash equivalents 1,037 Accounts receivable 6,124 Inventories, net 14,728 Prepaid expenses and other current assets 263 Other current assets 525 Intangible assets 4,579 Property, plant and equipment net 301 Deferred tax asset 295 Accounts payable (10,934 ) Accrued liabilities (534 ) Prepaid income tax 89 Advance from customers (230 ) Short term borrowings (4,305 ) Deferred tax liability (1,889 ) Identifiable net assets acquired (a) 10,049 Consideration (b) 15,578 Non-controlling interests (c) 2,709 Goodwill (b+c- a) 8,238 During the period from the acquisition date to June 30, 2015, Solar Juice contributed revenue of $4,754 and losses of $71 to the Company’s consolidated results. Solar Juice is one of the largest distributors of solar panels and inverters in Australia and have well established distribution channel in South East Asia. As a result of the acquisition of Solar Juice, the Company would be able to have immediate access to the solar PV market in Australia, New Zealand and South East Asia, which could enhance the Company’s development of PV projects in those markets. Goodwill primarily represents such expected synergies the Company obtained from the acquisition. Pursuant to the Purchase Agreement, the Company was granted a call option by the Solar Juice Sellers to acquire remaining 20% equity interest in Solar Juice from them. The exercise price per share of the call option is to be determined based on Solar Juice’s earnings before interest, taxation, depreciation and amortization (“EBITDA”) per share for the year ending December 31, 2015 multiplied by six. The acquisition consideration will be settled with the Company’s common stock if the Company exercises the option. The number of shares to be issued by the Company will be determined by the share price on the exercise date. The call option will be expired on May 28, 2016. The call option meets the definition of a derivative. The Company initially recognized the call option at its fair value of $420 as a derivative asset in Other current assets on the consolidated balance sheet as of June 30, 2015 with gain of $4 arising from the change in fair value recorded in the consolidated statement of operations for the three-month and six-month periods ended June 30, 2015. The fair value measurement of this call option was further discussed in Note 12 — Fair value measurement. Additionally, Solar Juice received a Notice to Produce Documents request from the Australian Customs Border Protection Service in relation to the tariff classification of certain imports, consistent with similar requests issued to other companies in the solar photovoltaic industry in October 2014. Whilst no official claim for payment has been made on Solar Juice by the Australian Customs Border Protection Service, Solar Juice has submitted an application for an internal review via the Tariff Advice mechanism in January 2015 and is awaiting responses from customs. Based on an internal review by management of the Company as well as external legal advice, Solar Juice considered no significant liability will arise and disclosed the contingency liability (not including any penalties or charges if any) amounting to US$700 as of May 28, 2015. Pursuant to the Purchase Agreement, tax liabilities arising for the period before the closing date of the acquisition will be indemnified by the Solar Juice Sellers. Therefore, the Company considered that no significant liability has been assumed in connection with this acquisition. (c) Acquisition of All-Zip On April 30, 2015, the Company entered into a share purchase agreement (the “Share Purchase Agreement”) with Shanghai All-Zip Roofing System Group Co., Ltd. (“All-Zip”), a company established in China, and all of its shareholders (collectively, the “All-Zip Sellers”) to acquire 100% equity interests in All-Zip, subject to certain closing conditions set forth in the Share Purchase Agreement, at an aggregate consideration of RMB275 million (equivalent to $44.35 million), which are to be settled by the issuance of the Company’s common stock at $2.38 per share. As at the date of issuance of these financial statements, the acquisition has not been consummated.

Receivables [Abstract]
Accounts Receivable	7. Accounts receivable Accounts receivable, current and non-current, mainly represents amounts due from customers for 1) sales of Solar PV projects; 2) rendering of EPC services; 3) supply of electricity under power supply agreements (“PPA”); and 4) sales of solar PV related components. An allowance for doubtful accounts is provided against gross accounts receivable balances based on the Company’s best estimate of the amount of probable credit losses in the Company’s accounts receivable. The Company grants credit terms to credit-worthy customers. Terms vary per contract terms and range from 30 to 365 days. Contractually, the Company may charge interest for extended payment terms and require collateral. The Company regularly monitors and assesses the risk of not collecting amounts owed by customers. This evaluation is based upon a variety of factors, including an analysis of amounts current and past due along with relevant history and facts particular to the customer. The Company does not have any off-balance-sheet credit exposure related to its customers. Included in the receivable balances arising from EPC services as at June 30, 2015 and December 31, 2014 was an amount of $13,545 and $6,794 respectively due from a customer in the PRC, Xinyu Realforce Energy Co., Ltd (“Realforce”). In the second half of 2014, the Group entered into an EPC contract with Realforce to construct a 21MW rooftop PV station. The construction of the PV station had been completed prior to December 31, 2014. In April 2015, Realforce entered into a sales and leaseback arrangement with the Company for the purpose of settling part of the outstanding receivable arising from the EPC contract. At that time, the outstanding receivable balances due from Realforce amounted to $24,840. Pursuant to the sales and leaseback arrangement, Realforce sold the Company certain solar PV components installed in the 21MW rooftop PV station at their fair value of $11,292 and then immediately leased them back over a 10-year period with annual interest rate of 10% per annum under a finance lease contract. As a result of the above arrangement, the Company reduced the receivable balance due from Realforce by the fair value of the solar PV components of $11,292 and recognized a finance lease receivable of $11,292 due from Realforce. No gain or loss was immediately recognized in the condensed consolidated statement of operation in relation to the above settlement through sales and leaseback arrangement. For the remaining $13,545 accounts receivable balances due from Realforce, the Company is still negotiating a settlement arrangement with Realforce and the primarily settlement arrangement is to settle the accounts receivable in November 2015. As at June 30, 2015, 100% equity interests in Realforce were pledged to the Company to secure its repayment obligations under the finance lease contract and the outstanding accounts receivable balances.

Project Assets	8. Project Assets As of June 30, 2015, project assets, current and non-current, mainly consist of the SEF development across U.S.A., UK, Japan and the PRC, with the amount of $49,456 (2014: $48,520), $36,191 (2014: $14,000), $21,372 (2014: $12,826) and $33,746 (2014: 19,849) respectively. Project assets consist of the following: June 30, December 31, Under development-Company as project owner $ 107,235 $ 75,346 Under development-Company expected to be project owner upon the completion of construction* 33,530 19,849 Total project assets 140,765 95,195 Current, net of impairment loss $ 74,378 $ 73,930 Noncurrent $ 66,387 $ 21,265 * All of the projects costs under this category were recorded as project assets, noncurrent. Project assets under development-Company as project owner are primarily related to the following projects: Calwaii Projects In 2014, the Company acquired solar PV assets, primarily including land use right and pre-contract costs relating to forty-three solar PV systems owned by Calwaii. During the three-month period ended June 30, 2015, sales of four solar PV systems were consummated (see below). As of June 30, 2015 and December 31, 2014, incurred costs for PV solar systems under the Calwaii’s projects in Hawaii amounted to $23,270 and $23,943 respectively. Solar Mountain Creek Parent LLC The carrying amount of this project amounted to $17,629 and 17,864, net of impairment of $2,290 and $2,055 as of June 30, 2015 and December 31, 2014 respectively. Pursuant to a letter of intent dated November 10, 2014 and a sales agreement dated December 31, 2014, the Company agreed to sell the PV solar systems of this project upon its completion of construction at a consideration of $17,864. Management assessed the recoverable amounts of this project asset and as a result the carrying amount of this project asset was written down to the recoverable amount by $2,055. The estimate of recoverable amount of this project asset was based on this asset’s fair value less costs of disposal, and the fair value was determined by reference to the quoted price from third party for this project asset. The Company accounted for this sales transaction using the deposit method under ASC 360-20, real estate accounting, and did not recognize any revenue and profit for this sale transaction for the year ended December 31, 2014 and the six-month period ended June 30, 2015 as certain closing conditions as specified in the sales agreement had not been met and accordingly sales had not been consumated as of June 30, 2015. RE Capital Projects In April 2015, the Company entered into an interest purchase agreement with RE Capital Pte. Ltd. to acquire its 100% membership interest in seventeen PV project companies in Japan (“RE Capital companies”) at a consideration of $8,800 consisting of $3,300 cash and $5,500 worth of the Company’s common stock (See Note 17 — Stockholders’ Equity). RE Capital companies’ total assets and liabilities only included land and pre-contract cost related to solar projects of 52MWs in total. Additionally, RE Capital companies had not entered into any power generation contracts with any utilities companies. As a result, Management concluded that the acquisition of 100% managing member interest in RE Capital companies did not meet the definition of a business combination as the primary inputs (the solar plant, which had yet to be constructed) were not available on the acquisition date. As of June 30, 2015, the payment made and cost incurred of $7,362 in total up to June 30, 2015 were included and recorded as project assets. Solar Park Development 4 Ltd In June 2015, the Company entered into another shares sales agreement with Blackrock Income UK Holding Limited to transfer the 100% outstanding share of Solar Park Development 4 Ltd at a consideration of $10,693 (equivalent to GBP7,000), which owned a grid-connected solar project of 6.2 MW developed by the Company. The Company accounted for this sales transaction using the deposit method under ASC 360-20, real estate accounting as of June 30, 2015. As of June 30, 2015, the Company didn’t recognize any revenue and profit for this sale transaction as certain closing conditions specified in the agreement had not been met and accordingly the sales had not been consummated. As of June 30, 2015 and December 31, 2014, the related project asset costs recorded and included as project assets amounted to $10,163 and $2,022 respectively. Other Projects In addition to the above significant projects, the Company’s project assets consists of a number of individually insignificant projects of $48,811 and $31,517 in aggregate as of June 30, 2015 and December 31, 2014 respectively, of which $31,443 and $13,643 of project assets were under construction respectively. During the six-month and three-month periods ended June 30, 2015, the Company recognized sales revenue for the following projects: Calwaii Projects Pursuant to a sales agreement dated September 18, 2014, the Company agreed to sell four out of the thirty-nine PV solar systems of Calwaii’s project upon their completion of construction at a consideration of $5,860. The Company accounted for this sales transaction under ASC 360-20, real estate accounting, and did not recognize any revenue and profit for this sales transaction for the year ended December 31, 2014 and three-month period ended March 31, 2015 as certain closing conditions, including but not limited to grid connection specified in the sales agreement, had not been met. As of June 30, 2015, all closing conditions had been met and sales had been consummated. Accordingly, the Company recognized revenue and cost for these solar projects of $5,860 and $5,850, respectively. Solar Park Development 3 Ltd In June 2015, the Company entered into a shares sales agreement with Blackrock Income UK Holding Limited to transfer the 100% outstanding share of Solar Park Development 3 Ltd at a consideration of $16,088 (equivalent to GBP10,532), which owned a grid-connected solar project of 9.5 MW developed by the Company. The Company accounted for this sales transaction under ASC 360-20, real estate accounting. As of June 30, 2015, all closing conditions specified in the shares sales agreement had been met and the Company recognized revenue and cost for this solar project of $16,088 and 14,854, respectively during the three-month period ended June 30, 2015. The receivable of $16,088 were fully settled by Blackrock Income UK Holding Limited in July 2015. Project assets under development-Company expected to be project owner upon completion of construction are related to the following projects: In late 2014, the Company entered into two EPC contracts with third-party projects owners under an arrangement pursuant to which there was mutual understanding between the Company and the respective project owners that the title and ownership of the PV solar power systems would transfer to the Company upon the completion of construction and grid connection of the PV systems under the EPC contracts by the Company. The PV solar systems were pledged to the Company, as part of the EPC contract terms, to secure the expected title transfer upon grid connection. In 2015, the Company entered into similar arrangement with two third-party project owners. Unlike other EPC contracts which are accounted for in accordance with ASC 605, no revenue is recognized for these four EPC contracts as no revenue is expected to be realized or earned from the EPC contracts, which were signed to facilitate the construction of the related solar PV systems by the Company and secure the Company’s financial interests in these projects through the pledge of the related solar PV systems. Given the substance of the transactions, the mutual understanding reached between the Company and the third-party project owners and the remote possibility of not obtaining the legal title upon grid connection, the Company accounts for these projects as owned and record the costs incurred under Project Assets on the condensed consolidated balance sheet. Based on the Company’s intention to sell or hold for own use, the projects costs incurred for these EPC contracts are presented as operating activities or investing activities respectively in the condensed consolidated statement of cash flows. As of June 30, 2015, the Company had respectively entered with these projects owners either a memorandum of understanding or pre-acquisition agreement to confirm the future transfer of the title and ownership upon the completion of construction and grid connection of the related PV systems.

Fair Value Disclosures [Abstract]
Fair Value Measurement	12. Fair value measurement In arriving at fair-value estimates of the call option as discussed in Note 4- Business combination, the Company utilizes the most observable inputs available for the valuation technique employed. If a fair-value measurement reflects inputs at multiple levels within the fair value hierarchy, the fair-value measurement is characterized based upon the lowest level input. For the Company, recurring fair-value measurements are performed for the derivative assets. The Company does not have any derivative asset that reduce risk associated with hedging exposure and has not designated the derivative asset as a hedge instrument. The Company did not have any derivatives valued using Level 1 and Level 2 inputs as of June 30, 2015 and December 31, 2014. The derivative asset relating to the call option was classified in Level 3 of the fair value hierarchy in which management has used at least one significant unobservable input in the valuation model. The fair value of the derivative asset was $420 and $424 at the grant date of May 28, 2015 and June 30, 2015 respectively, which were recorded as other financial assets in the Consolidated Balance Sheet as of June 30, 2015. Gain arising from change in fair value of $4 was recorded as Other income-others in the consolidated statement of operations for the six-month and three-month periods ended June 30, 2015. The Company determines the fair value using binomial model with significant input on the fair value of the remaining 20% equity interest of Solar Juice and volatility unobservable in the market. The volatility is determined by the average standard derivation of the comparable companies applicable over a time period corresponding to the remaining life of the call option. Significant increases or decreases in this unobservable input would result in a significantly lower or higher fair value measurement. There have been no transfers between Level 1, Level 2, or Level 3 categories. There were no assets or liabilities measured on a non-recurring basis as of June 30, 2015 and December 31, 2014. For financial instruments that are not required to be measured at fair value, the following method and assumptions were used to estimate the fair value as at June 30, 2015 and December 31, 2014: Cash and cash equivalents, restricted cash, accounts receivable and payable, short term investments, bank deposits with maturity over three months, finance lease receivables, current, accrued liabilities, advance from customers and other current liabilities — costs approximates fair value because of the short maturity period. Notes receivable, current, and notes receivable, noncurrent — The fair value of Notes receivable, current were based on anticipated cash flows, which approximates carrying value, and were classified in Level 2 of the fair value hierarchy. The fair value of Notes receivable, noncurrent were classified in Level 3 of the fair value hierarchy. The Company used multiple techniques, including an income approach applying discounted cash flows approach, to measure the fair value using Level 3 inputs; the results of each technique have been reasonably weighted based upon management’s judgment applying qualitative considerations to determine the fair value at the measurement date. The fair value of notes receivable is determined to approximate its carrying value. Convertible bonds. The estimated fair value was $56,119 and $39,423 as of June 30, 2015 and December 31, 2014. The fair value of convertible bonds was classified in Level 2 of the fair value hierarchy. The Company determines the fair value using binomial model with significant input on prices and votes observable in the market. Short term borrowings. The carrying amount approximates fair value due to the short maturity and their variable market rates of interest that change with current Prime and no change in counterparty credit risk and were classified as Level 2 of the fair value hierarchy. Finance lease receivables, noncurrent, and other noncurrent liabilities. The Company used discounted cash flow approach to determine the fair value, which was classified in Level 3 of the fair value hierarchy. The fair value of finance lease receivables, noncurrent, and other noncurrent liabilities is determined to approximate its carrying value.

Convertible Bonds In December, 2014 the Company entered into three convertible promissory note purchase agreements with Brilliant King, Poseidon and Union Sky, respectively whereby the Company agreed to sell and issue to these three investors convertible promissory notes in an aggregate principal amount of $35,000 which could be converted into 17,500,000 Common Shares at a fixed conversion price of $2 unless adjusted for anti-dilution. The convertible notes bore no interest, and might be partially or wholly converted into shares of the Company’s common stock at any time prior to maturity at the option of the investor. The convertible promissory notes was due and payable on June 11, 2016 and are reclassified as current liabilities as of June 30, 2015. On June 15, 2015, the Company entered into a convertible promissory note purchase agreement with Vision Edge Limited (“Vision Edge”), whereby the Company agreed to sell and issue to Vision Edge convertible promissory note in an aggregate principal amount of $20,000 which could be converted into 7,407,410 Common Shares at a fixed conversion price of $2.70 unless adjusted for anti-dilution. The convertible notes bore no interest, and might be wholly converted into shares of the Company’s common stock at any time prior to maturity at the option of the investor. The commitment date of the convertible promissory note is on June 29, 2015. The convertible promissory note was due and payable on June 29, 2016. Also, as mentioned in Note 16, on June 15, 2015, the Company entered into option agreement with Vision Edge, whereby the Company agreed to grant Vision Edge an option to purchase from the Company a total of 7,407,410 Shares for an aggregate purchase price of $20,000, or $2.70 per share, prior to December 15, 2015. The above instruments issued to Vision Edge on June 15, 2015, including convertible promissory note and stock option, were accounted for as a bundled transaction. The proceeds from the issuance of convertible promissory note were allocated to the two elements based on the relative fair values of the convertible promissory note and the stock options at the time of issuance. There is no beneficial conversion feature in this convertible promissory note because the initial conversion price of US$ 2.66 per share after the proceeds are allocated to the option is greater than the fair value of the Company’s common stock on the commitment date of June 29, 2015. The convertible promissory note and stock options were initially recorded at $19,705 and $295, respectively, according to the allocation of the total proceeds. The discount of $295 of the convertible promissory note is amortized as interest expense using the effective interest rate method through the earliest demand payment date, i.e. June 29, 2016. The stock option was accounted for as an equity instrument and was recorded within equity.

Determining Fair Value Valuation and Amortization Method Expected Term Expected Volatility Expected Dividend Risk-Free Interest Rate Assumptions used in the determination of the fair value of share-based payment awards using the Black-Scholes model for stock option grants during the three-month and six-month periods ended June 30, 2015 and 2014 were as follows: For the Three Months Ended For the Six Months Ended June 30, 2015 June 30, 2014 June 30, 2015 June 30, 2014 Expected term 4 3.75 4 3.75 Risk-free interest rate 1.32% - 1.72% 1.25 % 1.32% - 2.24% 1.25 % Expected volatility 139% - 141% 1.22 % 139% - 142% 1.22 % Expected dividend yield 0% 0 % 0% 0 % Equity Incentive Plan On November 15, 2006, subject to approval of the stockholders, the Company adopted the 2006 Equity Incentive Plan (the “Plan”) which permits the Company to grant stock options to directors, officers or employees of the Company or others to purchase shares of common stock of the Company through awards of incentive and nonqualified stock options (“Option”), stock (“Restricted Stock” or “Unrestricted Stock”) and stock appreciation rights (“SARs”). The Plan was approved by the stockholders on February 7, 2007. The Company has granted time-based share options and restricted stock under the Plan to directors, officers, employees and individual consultants of the Company. The time-based options generally vest 25% annually and expire five to ten years from the date of grant. Total number of shares reserved and available for grant and issuance pursuant to this Plan is equal to 9% of the number of outstanding shares of the Company. Shares issued under the Plan will be drawn from authorized and unissued shares or shares now held or subsequently acquired by the Company. Outstanding shares of the Company shall, for purposes of such calculation, include the number of shares of stock into which other securities or instruments issued by the Company are currently convertible (e.g., convertible preferred stock, convertible debentures, or warrants for Common Stock), but not outstanding options to acquire stock. At June 30, 2015 there were 2,623,210 shares available for grant under the plan (9% of the outstanding shares of 676,867,538 less options and restricted stock outstanding and exercised since inception). The exercise price of any Option will be determined by the Company when the Option is granted and may not be less than 100% of the fair market value of the shares on the date of grant, and the exercise price of any incentive stock option granted to a stockholder with a 10% or greater shareholding will not be less than 110% of the fair market value of the shares on the date of grant. The exercise price per share of a SAR will be determined by the Company at the time of grant, but will in no event be less than the fair market value of a share of Company’s stock on the date of grant. On January 12, 2015 and February 23, 2015, the Board of Directors approved the grants of restricted stock unit awards (“RSU”) to core management members, other management and staff, pursuant to the terms of the 2006 Equity Incentive Plan. The total number of RSUs granted is 20,384,000 shares. Among these, the vesting schedules for the chairman, CEO and CFO (“core management”) are 100% vested at the grant date and the vesting schedules for the rest RSUs granted to other management and staff would be vested within the next four years equally. The Company used the market price of its share at grant date as the fair value of the RSUs in calculating the stock based compensation expense. The core management exercised all RSUs of 19,200,000 and all these shares were issued to them in March 2015 (See Note 17 — Stockholders’ Equity).

Earnings Per Share [Abstract]
Net Loss Per Share of Common Stock	20. Net Loss Per Share of Common Stock Basic loss per share is computed by dividing income attributable to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted loss per share reflects the potential dilution of shares by adding other Common Stock equivalents, including Common Stock options, warrants, and restricted Common Stock, in the weighted average number of common shares outstanding for a period, if dilutive. Potentially dilutive shares are excluded from the computation if their effect is anti-dilutive. As a result of the net loss for the six-month and three-month periods ended June 30, 2015 and 2014, there is no dilutive impact to the net loss per share calculation for the period. The following table presents the calculation of basic and diluted net loss per share: For the Three Months Ended For the Six Months Ended June 30, 2015 June 30, 2014 June 30, 2015 June 30, 2014 Numerator: Net loss attributable to stockholders $ (14,152 ) $ (1,340 ) $ (51,604 ) $ (2,170 ) Denominator: Basic and diluted weighted-average common shares 605,589,978 204,395,775 595,100,462 201,322,191 Basic net loss per share $ (0.02 ) $ (0.01 ) $ (0.09 ) $ (0.01 ) Diluted net loss per share (0.02 ) (0.01 ) (0.09 ) (0.01 )

These amounts, less related amortization, are included in accrued liabilities. These guarantees for the Aerojet 1 project are accounted for separately from the financing obligation related to the Aerojet 1 project because they are with different counterparties. Financing Obligation Performance Guaranty Product Warranties During the quarter ended September 30, 2007 and continuing through the fourth quarter of 2010, the Company installed own manufactured solar panels. Other than this period, the Company only installed panels manufactured by unrelated third parties as well as the Company’s principal shareholder and formerly controlling shareholder, LDK. Certain PV construction contracts entered into during the recent years included provisions under which the Company agreed to provide warranties to the buyer. As a result, the Company recorded the provision for the estimated warranty exposure on these contracts within cost of sales. Since the Company do not have sufficient historical data to estimate its exposure, the Company have looked to its own historical data in combination with historical data reported by other solar system installers and manufacturers. Due to the absence of historical material warranty claims, the Company have not recorded a material warranty accrual related to solar energy systems as of June 30, 2015 and December 31, 2014.

The occurrence of non-fulfillment of those closing conditions are not considered as remote. Contingencies From time to time, the Company is involved in various other legal and regulatory proceedings arising in the normal course of business. While the Company cannot predict the occurrence or outcome of these proceedings with certainty, it does not believe that an adverse result in any pending legal or regulatory proceeding, individually or in the aggregate, would be material to our consolidated financial condition or cash flows; however, an unfavorable outcome could have a material adverse effect on our results of operations for a specific interim period or year.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The condensed consolidated financial statements are unaudited and have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) for interim financial information. They should be read in conjunction with the financial statements and related notes to the financial statements of Solar Power, Inc. for the years ended December 31, 2014 and 2013 appearing in Solar Power, Inc.’s Form 10-K filed with the Securities and Exchange Commission (“SEC”) on March 31, 2015. The Company’s June 30, 2015 and 2014 unaudited interim condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the SEC for smaller reporting companies and include the accounts of Solar Power, Inc. and its subsidiaries. Certain information and note disclosures normally included in the annual financial statements on Form 10-K have been condensed or omitted pursuant to those rules and regulations, although the Company’s management believes the disclosures made are adequate to make the information presented not misleading. In the opinion of management, all adjustments, consisting of normal recurring adjustments and reclassifications, necessary to present fairly the Company’s consolidated financial position, results of operations and cash flows for all periods presented have been reflected herein. The Company’s financial position, operating results, cash flows and trends in these unaudited condensed consolidated financial statements are not necessarily indicative of future results that may be expected for any other interim period or for the full year. The preparation of unaudited interim condensed consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the unaudited interim consolidated financial statements as well as the reported amounts of revenues and expenses during the reporting period. Significant accounting estimates used in the preparation of the Company’s consolidated condensed financial statements include: allowance made for doubtful accounts receivable, inventory write-downs, the estimated useful lives of long-lived assets, the impairment of goodwill, long-lived assets and project assets, fair value of derivative liability, valuation allowance of deferred income tax assets, accrued warranty expenses, the grant-date fair value of share-based compensation awards and related forfeiture rates, and fair value of financial instruments. Actual results could differ from those estimates upon subsequent resolution of identified matters. The unaudited interim condensed 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.
Recently Issued Accounting Pronouncements	In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606), to clarify the principles of recognizing revenue and create common revenue recognition guidance between U.S. GAAP and International Financial Reporting Standards. An entity has the option to apply the provisions of ASU 2014-09 either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying this standard recognized at the date of initial application. ASU 2014-09 is effective for fiscal years and interim periods within those years beginning after December 15, 2017, and early adoption is permitted for periods beginning after December 15, 2016. The Company has not determined which transition method it will adopt, and is currently evaluating the impact of this standard on its consolidated financial statements. In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements — Going Concern (Subtopic 205- 40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, which requires management to evaluate, at each annual and interim reporting period, whether there are conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date the financial statements are issued and to provide related disclosures. ASU 2014-15 is effective for the Company for the fiscal year ending December 31, 2016 and for interim periods thereafter. The Company is currently evaluating the impact of this standard on its consolidated financial statements. In January 2015, the FASB issued ASU No. 2015-01, Income Statement — Extraordinary and Unusual Items (Subtopic 225- 20), which eliminates the concept of reporting for extraordinary items. ASU 2015-01 is effective for the Company for fiscal years, and interim periods within those fiscal years, beginning on January 1, 2016. The Company is currently evaluating the impact of this standard on the Company’s consolidated financial statements. On February 18, 2015, the FASB issued ASU No. 2015-02, Consolidation, which reduces the number of consolidation models and simplifies the current standard. Entities may no longer need to consolidate a legal entity in certain circumstances based solely on its fee arrangements when certain criteria are met. ASU 2015-02 reduces the frequency of the application of related-party guidance when determining a controlling financial interest in a variable interest entity. ASU 2015-02 is effective for the Company’s fiscal year ending December 31, 2016. The Company is currently evaluating the impact of this standard on the Company’s consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-03, Interest — Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. ASU 2015-03 is effective for the Company on a retrospective basis on January 1, 2016. Early adoption is permitted, but only for debt issuance costs that have not been reported in financial statements previously issued or available for issuance. The Company is currently evaluating the impact of this standard on the Company’s consolidated financial statements.

Sales-leaseback, lease description	In April 2015, Realforce entered into a sales and leaseback arrangement with the Company for the purpose of settling part of the outstanding receivable arising from the EPC contract. At that time, the outstanding receivable balances due from Realforce amounted to $24,840. Pursuant to the sales and leaseback arrangement, Realforce sold the Company certain solar PV components installed in the 21MW rooftop PV station at their fair value of $11,292 and then immediately leased them back over a 10-year period with annual interest rate of 10% per annum under a finance lease contract. As a result of the above arrangement, the Company reduced the receivable balance due from Realforce by the fair value of the solar PV components of $11,292 and recognized a finance lease receivable of $11,292 due from Realforce. No gain or loss was immediately recognized in the condensed consolidated statement of operation in relation to the above settlement through sales and leaseback arrangement. For the remaining $13,545 accounts receivable balances due from Realforce, the Company is still negotiating a settlement arrangement with Realforce and the primarily settlement arrangement is to settle the accounts receivable in November 2015. As at June 30, 2015, 100% equity interests in Realforce were pledged to the Company to secure its repayment obligations under the finance lease contract and the outstanding accounts receivable balances.
