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 PV solutions for business, residential, government and utility customers and investors. The Company provides a full spectrum of EPC services to third party project developers, as well as develop, own and operate solar 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 March 31, 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.) & Italsolar S.r.l (collectively as “CECEP”), 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. Xinwei Suzhou and Xinyu Xinwei were incorporated in the PRC in 2014 in connection with the expansion of the Company’s full spectrum EPC service business in the PRC. Sinsin and Xinte were acquired by the Company in 2014, and CECEP was acquired by the Company in 2015 (see Note 4), for ramping up its portfolio of global solar projects. 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, chief executive officer 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 follows: Power of attorney: Call option agreement: Equity pledge agreement: 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. The financial results of Solar Energy are expected to be consolidated by the Company once the legal enforceability of the contractual agreements is established. Through the on-line platform of Solar Energy, the Company raised funds from individual investors on PV projects basis. For each fund raising PV project launched on the on-line platform, individual investors may subscribe the purchasing of solar module which will then be leased to the project developer of the PV project over a specified period. These PV projects may represent the Company’s self developed projects or third party developed projects, Although a tri-party lease agreement is signed among the individual investors, the Company and the project developer of the project launched, the purchase of any solar panels from vendors are solely contracted by the Company and the Company bears full credit risk in respect of the collection of the lease payments from project developers. The lock-up period for investment made by the individual investors for each fund raising project normally ranges from 0-720 days. Individual investors are guaranteed by the Company with an investment return for their investments, which ranges from an annual rate of 8% to 10.3% for the three months ended March 31, 2015, and are guaranteed by the Company in respect of the repayment of funds at the end of the Investment Period. Solar Energy collects the funds provided by the individual investors and settles with the Company on a bi-weekly basis. For the service provided through the on-line platform, Solar Energy charged the Company commission fee based on 1% of the fund principal (see Note 22— Related Party Transactions). The interest bearing funds provided by individual investors to the Company are recorded on the condensed consolidated balance sheet as either short term or long term borrowings. Lease accounting is adopted for any solar panels purchased by the Company for leasing to third party project developers. During the three months ended March 31, 2015, all leases of solar module to third party developer under the above arrangement are classified as finance lease with the Company as lessor and third party project developer as lessee. Finance lease income of $3 was earned and recorded as interest income for the three months ended March 31, 2015. In connection with the launch of the above financing and leasing products, the Company issued coupons with total face value of $2,881 to third party vendors and two related parties during the three-month period ended March 31, 2015. These coupons are freely transferrable between holders but could not be redeemed in cash. Each coupon has an expiry date for redemption. Prior to the expiry date, when the holders subscribe the purchasing and leasing of solar modules through the on-line platform owned by Solar Energy described above, the holders could redeem the coupons such that the purchase price to be paid would be reduced by the face value of the coupons. As of March 31, 2015, all coupons issued to these vendors and related parties had been redeemed. In respect of the coupons issued above, coupons totaling $219 were recorded as settlement of trade payable balances in the same amount as agreed with the corresponding third party vendors receiving the coupons. For the remaining amounts, the Company recognized other receivable due from third party vendors and a related party of $1,301 and $779, respectively, and recorded selling expenses of $582 in the condensed consolidated financial statements for the three months ended March 31, 2015. 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 March 31, 2015 and 2014 unaudited interim condensed consolidated financial statements on Form 10-Q 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.

Accounting Changes and Error Corrections [Abstract]
Recently Issued Accounting Pronouncements	3. Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU 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 Accounting Standards Update (“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 Combination	4. Business combination 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 (i) CECEP Solar Energy (Luxembourg) Private Limited Company (S.a.r.l.), a limited liability company registered in Luxembourg, and (ii) Italsolar S.r.l., a limited liability company registered in Italy, (collectively as “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. As of March 31, 2015, $2,283 was recorded in other liabilities for the outstanding cash settlement in the Condensed Consolidated Financial Statements. 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 March 31, 2015, the acquired subsidiary contributed revenue of $194 and earnings of $42 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. The excess of purchase price over the identifiable net tangible and intangible assets acquired was recorded as goodwill.

Fair Value Disclosures [Abstract]
Fair Value Measurement	11. Fair value measurement As discussed in Note 7— Project Assets, the Company issued contingent consideration as part of a transaction to acquire assets from HPL in September 2014. The Company issued the third party $3,300 to be paid with shares of the Company’s Common Stock at a price per share equal to $1.10 or 3,000,000 shares of Common Stock, subject to an adjustment which indicates that if the dollar volume-weighted average price (“VWAP”) for the Company’s Common Stock is less than $1.00 per share for the five trading days prior to March 30, 2015, then the Company shall issue HPL additional shares of Common Stock so that the total number of shares issued by the Company under the agreement multiplied by the five day VWAP will have a value of at least $3,000 on March 30, 2015. The contingent consideration meets the definition of a derivative and the Company has recorded the fair value of such derivative as a derivative liability which is included in other current liabilities in the Consolidated Balance Sheet as of December 31, 2014 and the change in fair value was recorded in the Condensed Consolidated Statement of Operations for the three months ended March 31, 2015. This derivative was expired on March 30, 2015. In arriving at fair-value estimates, 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 liability. The derivative liability is recognized in the balance sheet at fair value. Changes in the fair value of the derivative liability are reported in the Condensed Consolidated Statement of Operations. The Company does not have any derivative liabilities that reduce risk associated with hedging exposure and has not designated the derivative liability as a hedge instrument. The Company did not have any derivatives valued using Level 1 and Level 2 inputs as of March 31, 2015 and December 31, 2014. The fair values and corresponding classifications under the appropriate levels of the fair value hierarchy of the outstanding derivative liability recorded as recurring liabilities in the Condensed Consolidated Balance Sheet consisted of the following: Level March 31, 2015 December 31, 2014 Included in other current liabilities: Derivative liability 3 $ — $ 11 The following table presents quantitative information for Level 3 measurements: Fair value at December 31, 2014 Valuation technique Unobservable input Liabilities: Derivative liability $ 11 Black-Scholes option pricing model Prevailing interest rates, Company’s stock price volatility, expected term There have been no transfers between Level 1, Level 2, or Level 3 categories. Financial instruments classified as Level 3 in the fair value hierarchy represents the derivative liability in which management has used at least one significant unobservable input in the valuation model. The following table represents a reconciliation of activity for the derivative liability in order to arrive at the current derivative liability recorded at fair value as of March 31, 2015: Derivative Liability Opening balance – December 31, 2014 $ 11 Purchases, sales, issuances, and settlements — Transfers into and (or) out of Level 3 — Change in fair value (11 ) Closing balance – March 31, 2015 $ — Change in fair value of $11 is recorded as fair value change of derivative liability under other income in the Condensed Consolidated Statement of Operations. There were no assets or liabilities measured on a non-recurring basis as of March 31, 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 March 31, 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, accrued liabilities, advance from customers and other current liabilities –costs approximates fair value because of the short maturity period. Notes receivable, current, 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 $40,551 and $39,423 as of March 31, 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 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. 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 other noncurrent liabilities is determined to approximate its carrying value.

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 three 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 March 31, 2015 there were 1,335,374 shares available for grant under the plan (9% of the outstanding shares of 601,270,944 less options and restricted stock outstanding and exercised since inception).

Earnings Per Share [Abstract]
Net Loss Per Share of Common Stock	18. 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 three months ended March 31, 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: March 31, 2015 March 31, 2014 Numerator: Net loss attributable to stockholders $ (37,452 ) $ (832 ) Denominator: Basic and diluted weighted-average common shares 584,519 198,214 Basic net loss per share $ (0.06 ) $ (0.00 ) Diluted net loss per share (0.06 ) (0.00 )

This option has been exercised on December 30, 2014 and this guarantee has been released accordingly. The Company has recorded on its Condensed Consolidated Balance Sheet the guarantees of $67 and $71 at March 31, 2015 and December 31, 2014. 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 March 31, 2015 and December 31, 2014. Operating leases — Future minimum payments under all of our non-cancelable operating leases are as follows as of March 31, 2015: 2015(remaining nine months) $ 1,495 2016 1,791 2017 1,393 Thereafter 10,398 $ 15,077 Capital commitments — The capital commitments as at balance sheet dates disclosed above do not include those incomplete acquisitions for investment and business as at balance sheet dates as the agreements could either be terminated unconditionally without any penalty or cancelable when the closing conditions as specified in the agreements could not be met. 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 March 31, 2015 and 2014 unaudited interim condensed consolidated financial statements on Form 10-Q 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 ASU 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 Accounting Standards Update (“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.
