PART I

ITEM 1.     BUSINESS

Overview

Solar Power, Inc. and its subsidiaries (collectively the “Company”), a California corporation, is a global solar energy facility (“SEF”) developer offering high-quality, low-cost distributed generation and utility-scale SEF development services. Primarily, we partner with developers around the world who hold large portfolios of SEF projects for whom we serve as co-developer and engineering, procurement and construction (“EPC”) contractor. In addition to developing SEFs using products manufactured by LDK Solar Co., Ltd. (“LDK”), our parent company, we also sell solar modules and balance of system components manufactured by third party vendors to other integrators in the U.S., Asian, and European markets.

In addition to designing, engineering and constructing large-scale SEFs, we also provide long-term operations and maintenance (“O&M”) services through our proprietary O&M program SPIGuardianTM. This service program provides a comprehensive suite of services that commence upon a facility’s commissioning to provide performance monitoring, system reporting, preventative maintenance and full warranty support over the anticipated life of the SEF. While we still consider our O&M services to be within our core competencies, we have obtained third party outsourcing for these services to assist in the reduction of operating expenses.

Our Strategy

As conventional energy costs rise and fossil fuels dwindle globally, the deployment of renewable energy grows. We believe solar energy will play an increasingly important role in the long term as a growing number of energy independence strategies are deployed worldwide. We presently are focused on the following steps to implement our business strategy:

Intellectual Property

We rely and will continue to rely on trade secrets, know-how and other unpatented proprietary information in our business. We have the following trademarks: Yes! Solar Solutions, Yes!, and Sky Mount®. In addition, we have four Patent Cooperation Treaty applications, four provisional patents pending, one patent application and one design application for certain proprietary technologies. The company is currently evaluating the necessity to continue with certain patent activities.

Competition

The solar power market is intensely competitive and rapidly evolving, and we compete with major international and domestic companies. Our major competitors in the development of SEFs include completely vertically integrated companies such as SunPower Corporation and First Solar, and companies such as Sun Edison (a wholly owned subsidiary of MEMC Electronic Materials, Inc.) plus numerous regional developers. We compete in the sale of our balance of system products with other manufacturers of racking systems for solar modules. The entire solar industry also faces competition from other power generation sources, both conventional sources, as well as other emerging technologies. Solar power has certain advantages and disadvantages when compared to other power generating technologies. The advantages include the ability to deploy products in many sizes and configurations, install products almost anywhere in the world, provide reliable power for many applications, serve as both a power generator and the skin of a building and eliminate air, water and noise emissions.

Manufacturing and Assembly Capabilities

As described previously, we no longer manufacture solar modules. Through contract manufacturing and assembly relationships, we continue to manufacture balance of system products. Our knowledge and experience of manufacturing and assembly operations in China give us a competitive advantage in the production of balance of system products. Our goal is to continue to reduce costs of the overall solar system to the end customer and ultimately make the actual installed cost of solar equivalent or comparable to the cost of grid-based energy without rebate. These overall reductions in cost will be delivered by reducing labor installation costs through better system design and kit packaging along with reductions in module and balance of system costs through a sustained focus on driving prices down on what are essentially commodity-like products.

Suppliers

Sales and Marketing

Our products and services are largely represented through our Company’s sales force located in California. To ensure adequate coverage of the markets we are targeting, we also work with outside sales representatives to cultivate opportunities. These representatives currently cover all viable solar markets; however our primary focus is on the United States (“U.S.”).

ITEM 1A.     RISK FACTORS

Investing in our common stock involves a high degree of risk. You should carefully consider the following risks and all other information contained in our public filings before making an investment decision about our common stock. This section should be read in conjunction with the Consolidated Financial Statements and the accompanying notes thereto, and Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations included in this Annual Report. While the risks described below are the ones we believe are most important for you to consider, these risks are not the only ones that we face. If any of the following risks actually occur, our business, operating results, liquidity or financial condition could suffer, the trading price of our common stock could decline, and you could lose all or part of your investment.

Risks Related to Our Business

Our risks and uncertainties include, without limitation, our ability to raise capital to finance our operations, the effectiveness, profitability and the marketability of our services, our ability to protect our proprietary information, general economic and business conditions, the impact of new or disruptive technological developments and competition, adverse results of any legal proceedings, the impact of current, pending or future legislation and regulation of the solar power industry, our ability to enter into acceptable relationships with one or more of our suppliers for panel components and the ability of such suppliers to manufacture products or components of an acceptable quality on a cost-effective basis, our ability to attract or retain qualified senior management personnel, including sales and marketing and technical personnel and other risks detailed from time to time in our filings with the Securities and Exchange Commission (“SEC”), including those described below. We do not undertake any obligation to update any forward-looking statements.

The execution of our strategy is dependent upon the continued availability of third-party financing arrangements for our customers.

Generally, our customers must enter into agreements to finance the construction and purchase of our SEF projects. These structured finance arrangements are complex and rely heavily on the creditworthiness of the customer, as well as required returns of the financing companies. Depending on the status of financial markets and general economic conditions overall, financial institutions may be unwilling or unable to finance the cost of construction of our SEF projects. Lack of credit for our customers or restrictions on financial institutions extending such credit will severely limit our ability to maintain or grow our revenues. In addition, an increase in interest or lending rates or a reduction in the supply of project debt financing could reduce the number of solar projects that receive financing, making it difficult for our customers to secure the financing necessary to develop, build, purchase or install an SEF on favorable terms, or at all, and thus lower demand for our SEFs which could limit our growth or reduce our net sales. We are currently seeking debt financing from CDB for customers of three completed projects in Greece. Without such financing, the Company will collect the outstanding development and construction receivables on the projects from the cash flow generated by the project operations over an extended period of time.

Our failure to raise additional capital or generate the significant capital necessary to maintain or expand our operations, or for construction of SEFs, could reduce our ability to compete and could harm our business growth or materially effect our operations.

Our ability to secure project financing for project development and our outstanding loans and line of credit from CDB may be adversely impacted by LDK Solar’s liquidation and our default under our Cathay Bank loan agreement.

Our business strategy depends on the widespread adoption of solar power technology and economics for the construction of SEFs, and if demand for such facilities fails to develop sufficiently, our revenues and ability to achieve or maintain profitability could be harmed.

While the demand for SEFs is emerging and rapidly evolving, its future success is uncertain. If solar power technology proves unsuitable for widespread commercial deployment or if demand for SEFs fails to develop sufficiently, we may not be able to generate enough revenues to achieve and sustain profitability. The factors influencing the widespread adoption of solar power technology through the construction of SEFs include but are not limited to:

The reduction or elimination of government and economic incentives domestically and changes in foreign incentives could cause our revenue to decline.

We believe that the growth of the market for “on-grid” applications, where solar power is used to supplement a customer’s electricity purchased from the utility network, depends in large part on the availability and size of government-generated economic incentives. At present, the cost of producing solar energy generally exceeds the price of electricity in the U.S. from traditional sources. To encourage the adoption of solar technologies, the U.S. government and numerous state governments have provided subsidies in the form of cost reductions, tax write-offs and other incentives to end users, distributors, systems integrators and manufacturers of solar power products. Reduction, elimination and/or periodic interruption of these government subsidies and economic incentives because of policy changes, fiscal tightening or other reasons may result in the diminished competitiveness of solar energy, and materially and adversely affect the growth of these markets and our revenues. Electric utility companies that have significant political lobbying powers may push for a change in the relevant legislation in our markets. The existing Federal Investment Tax Credit was renewed with passage of the 2008 economic stimulus package by the U.S. government. The current Federal Investment Tax Credit allows for a 30% tax credit for both commercial and residential solar installations placed into service on or before December 31, 2016 with no cap and allows the commercial credit to be monetized if it cannot be absorbed by a tax liability.

A significant portion of our prior direct module and balance of system sales occurred outside of the U.S. Changes in the feed-in tariffs in markets like Germany, Spain and Italy, will have a material impact on the financial viability of solar systems in those markets. Consequentially, our ability to sell products into those markets will be impacted. Changes to international programs are not easily forecasted and may happen rapidly, which may result in significant changes in demand for solar products.

We act as the general contractor for our customers in connection with the installations of our solar power systems and are subject to risks associated with construction, bonding, cost overruns, delays and other contingencies, which could have a material adverse effect on our business and results of operations.

We act as the general contractor for our customers in connection with the installation of our solar power systems. All essential costs are estimated at the time of entering into the sales contract for a particular project, and these are reflected in the overall price that we charge our customers for the project. These cost estimates are preliminary and may or may not be covered by contracts between us or the other project developers, subcontractors, suppliers and other parties to the project. In addition, we require qualified, licensed subcontractors to install most of our systems. Shortages of such skilled labor could significantly delay a project or otherwise increase our costs. Should miscalculations in planning a project or defective or late execution occur, we may not achieve our expected margins or cover our costs. Additionally, many systems customers require performance bonds issued by a bonding agency. Due to the general performance risk inherent in construction activities, it is sometimes difficult to secure suitable bonding agencies willing to provide performance bonding. In the event we are unable to obtain bonding, we will be unable to bid on, or enter into sales contracts requiring such bonding.

Delays in solar panel or other supply shipments, other construction delays, unexpected performance problems in electricity generation or other events could cause us to fail to meet these performance criteria, resulting in unanticipated and severe revenue and earnings losses and financial penalties. Construction delays are often caused by inclement weather, failure to timely receive necessary approvals and permits, or delays in obtaining necessary solar panels, inverters or other materials. The occurrence of any of these events could have a material adverse effect on our business and results of operations.

If there is an increase in the price of polysilicon, the corresponding increase in the cost of constructing SEFs may reduce the demand for SEFs, resulting in lower revenues and earnings.

Increases in polysilicon pricing could result in substantial downward pressure on the demand for SEFs due to the overall increase in the cost of production for such projects. Lessening demand for new SEFs may have a negative impact on our revenue and earnings and adversely affect our business and financial condition.

Our operating results may fluctuate significantly from period to period; if we fail to meet the expectations of securities analysts or investors, our stock price may decline significantly.

Several factors can contribute to significant quarterly and other periodic fluctuations in our results of operations. These factors may include but are not limited to the following:

We base our planned operating expenses in part on our expectations of future revenue, and we believe a significant portion of our expenses will be fixed in the short-term. If revenue for a particular quarter is lower than we expect, we likely will be unable to proportionately reduce our operating expenses for that quarter, which would harm our operating results for that quarter. This may cause us to miss analysts’ guidance or any guidance announced by us. If we fail to meet or exceed analyst or investor expectations or our own future guidance, even by a small amount, our stock price could fluctuate, perhaps substantially.

We may not be able to efficiently integrate the operations of our acquisitions, products or technologies.

From time to time, we may acquire new and complementary technology, assets and companies. We do not know if we will be able to complete any acquisitions or if we will be able to successfully integrate any acquired businesses, operate them profitably or retain key employees. Integrating any newly acquired business, product or technology could be expensive and time-consuming, disrupt our ongoing business and distract our management. We may face competition for acquisition targets from larger and more established companies with greater financial resources. In addition, in order to finance any acquisitions, we might be forced to obtain equity or debt financing on terms that are not favorable to us, and in the case of equity financing, our stockholders interests may be diluted. If we are unable to integrate effectively any newly acquired company, product or technology, our business, financial condition and operating results could suffer.

We face intense competition and many of our competitors have substantially greater resources than we do.

We compete with major international and domestic companies. Some of our current and potential competitors have greater market recognition and customer base, longer operating histories and substantially greater financial, technical, marketing, distribution, purchasing, manufacturing, personnel and other resources than we do. In addition, many of our competitors are developing and are currently producing products based on new solar power technologies that may ultimately have costs similar to or lower than our projected costs.

Some of our competitors own, partner with, have longer term or stronger relationships with solar cell providers than we do, which could result in them being able to obtain solar cells on a more favorable basis than us. It is possible that new competitors or alliances among existing competitors could emerge and rapidly acquire significant market share, which would harm our business. If we fail to compete successfully, our business would suffer and we may lose or be unable to gain market share.

Existing regulations and policies of the electric utility industry and changes to these regulations and policies may present technical, regulatory and economic barriers to the purchase and use of our products, which may significantly reduce demand for our products.

The market for electricity generating products is strongly influenced by federal, state and local government regulations and policies concerning the electric utility industry, as well as policies promulgated by electric utilities. These regulations and policies often relate to electricity pricing and technical interconnection of customer-owned electricity generation. In the U.S., these regulations and policies are being modified and may continue to be modified. Customer purchases of alternative energy sources, including solar power technology, could be deterred by these regulations and policies, which could result in a significant reduction in the demand for our solar power products. For example, without a regulatory-mandated exception for solar power systems, utility customers are often charged interconnection or standby fees for putting distributed power generation on the electric utility grid. These fees could increase the cost to our customers and make our solar power products less desirable.

The failure to increase or restructure the net metering caps could adversely affect our business. In the U.S., all grid-tied photovoltaic systems are installed with cooperation by the local utility providers under guidelines created through statewide net metering policies. These policies require local utilities to purchase from end users excess solar electricity for a credit against their utility bills. The amount of solar electricity that the utility is required to purchase is referred to as a net metering cap. If these net metering caps are reached and local utilities are not required to purchase solar power, or if the net metering caps do not increase in the locations where we install our solar product, demand for our products could decrease. The solar industry is currently lobbying to extend these arbitrary net metering caps and replace them with either notably higher numbers or with a revised method of calculation that will allow the industry to continue our expansion in a manner consistent with both the industry and state and federal desires.

Moreover, we anticipate that our solar power installation will be subject to oversight and regulation in accordance with national and local ordinances relating to building codes, safety, environmental protection, utility interconnection and metering and related matters.

It is difficult to track the requirements of individual states and design equipment to comply with the varying standards. Any new government regulations or utility policies pertaining to our solar power products may result in significant additional expenses to us, our resellers, and our customers and as a result, could cause a significant reduction in demand for our solar power products.

Compliance with environmental regulations can be expensive and noncompliance with these regulations may result in adverse publicity and potentially significant monetary damages and fines.

We are required to comply with extensive environmental laws and regulations at the national, state, local, and international levels. These environmental laws and regulations include those governing the discharge of pollutants into the air and water, the use, management, and disposal of hazardous materials and wastes, the cleanup of contaminated sites, and occupational health and safety. We have incurred and will continue to incur significant costs and capital expenditures in complying with these laws and regulations. In addition, violations of or liabilities under environmental laws or permits may result in restrictions being imposed on our operating activities or in our being subjected to substantial fines, penalties, criminal proceedings, third party property damage or personal injury claims, cleanup costs, or other costs. While we believe we are currently in substantial compliance with applicable environmental requirements, future developments such as more aggressive enforcement policies, and the implementation of new, more stringent laws and regulations, or the discovery of presently unknown environmental conditions may require expenditures that could have a material adverse effect on our business, results of operations, and financial condition.

We generally recognize revenue on system installations on a “percentage of completion” basis and payments are due upon the achievement of contractual milestones and any delay or cancellation of a project could adversely affect our business.

We generally recognize revenue on our system installations on a “percentage of completion” basis, and as a result, our revenues from these installations are driven by the performance of our contractual obligations, which is generally driven by timelines for the installation of our solar power systems at customer sites. This could result in unpredictability of revenue and in the near term, a revenue decrease. As with any project-related business, there is the potential for delays within any particular customer project. Variation of project timelines and estimates may impact our ability to recognize revenue in a particular period. In addition, certain customer contracts may include payment milestones due at specified points during a project. Because we must invest substantial time and incur significant expense in advance of achieving milestones and the receipt of payments, failure to achieve milestones could adversely affect our business and results of operations.

We are subject to particularly lengthy sales cycles in some markets.

Our focus on developing a customer base that requires installation of a solar power system means that it may take longer to develop strong customer relationships or partnerships. Moreover, factors specific to certain industries also have an impact on our sales cycles. Some of our customers may have longer sales cycles that could occur due to the timing of various state and federal subsidies. These lengthy and challenging sales cycles may mean that it could take longer before our sales and marketing efforts result in revenue, if at all, and may have adverse effects on our operating results, financial condition, cash flows and stock price.

Our competitive position depends in part on maintaining intellectual property protection.

Our ability to compete and to achieve and maintain profitability depends in part on our ability to protect our proprietary discoveries and technologies. We currently rely on a combination of copyrights, trademarks, trade secret laws and confidentiality agreements to protect our intellectual property rights. We also rely upon unpatented know-how and continuing technological innovation to develop and maintain our competitive position.

From time to time, the U.S. Supreme Court, other federal courts, the U.S. Congress or the U.S. Patent and Trademark Office may change the standards of patentability, and any such changes could have a negative impact on our business.

We may face intellectual property infringement claims that could be time-consuming and costly to defend and result in our loss of significant rights and the assessment of damages.

If we receive notice of claims of infringement, misappropriation or misuse of other parties’ proprietary rights, some of these claims could lead to litigation. We cannot provide assurance that we will prevail in these actions or that other actions alleging misappropriation or misuse by us of third-party trade secrets, infringement by us of third-party patents and trademarks or the validity of our patents will not be asserted or prosecuted against us. We may also initiate claims to defend our intellectual property rights. Intellectual property litigation, regardless of outcome, is expensive and time-consuming, could divert management’s attention from our business and have a material negative effect on our business, operating results or financial condition. If there is a successful claim of infringement against us, we may be required to pay substantial damages (including treble damages if we were to be found to have willfully infringed a third party’s patent) to the party claiming infringement, develop non-infringing technology, stop selling our products or using technology that contains the allegedly infringing intellectual property or enter into royalty or license agreements that may not be available on acceptable or commercially practical terms, if at all. Our failure to develop non-infringing technologies or license the proprietary rights on a timely basis could harm our business. Parties making infringement claims on future issued patents may be able to obtain an injunction that would prevent us from selling our products or using technology that contains the allegedly infringing intellectual property, which could harm our business.

We are exposed to risks associated with product liability claims in the event that installation of our solar power systems results in injury or damage, and we have limited insurance coverage to protect against such claims and additionally those losses resulting from business interruptions or natural disasters.

Since our solar power systems are electricity-producing devices, it is possible that users could be injured or killed by our systems, whether by improper installation or other causes. As an installer of products that are used by consumers, we face an inherent risk of exposure to product liability claims or class action suits in the event that the installation of the solar power systems results in injury or damage. Moreover, to the extent that a claim is brought against us, we may not have adequate resources to defend ourselves. We rely on our general liability insurance to cover product liability claims and have not obtained separate product liability insurance. The successful assertion of product liability claims against us could result in potentially significant monetary damages and, if our insurance protection is inadequate, could require us to make significant payments which could have a materially adverse effect on our financial results. Any business disruption or natural disaster could result in substantial costs and diversion of resources.

Since we cannot test solar panels for the duration of our vendors or the industry standard 25-year warranty period, we may be subject to unexpected warranty expense; if we are subject to warranty and product liability claims that our vendors do not cover, such claims could adversely affect our business and results of operations.

The possibility of future product failures could cause us to incur substantial expense to repair or replace defective products. We have agreed to indemnify our customers and our distributors in some circumstances against liability from defects in, or performance from, solar modules that we purchase and install. A successful indemnification claim against us could require us to make significant damage payments, which would negatively affect our financial results.

Standard product warranty for solar panel systems includes a 10-year warranty period for defects in materials and workmanship and a 25-year warranty period for declines in power performance from the modules. We believe our system warranty periods are consistent with industry practice. Due to the long warranty period, we bear the risk of extensive warranty claims long after we have shipped product and recognized revenue. Although we make every attempt to qualify our vendors and their solar panels, solar panels have not been and cannot be tested in an environment simulating the 25-year warranty period. As a result of the foregoing, we may be subject to unexpected warranty expense, which in turn would harm our financial results.

We may be unable to achieve our goal of reducing the cost of installed solar systems, which may negatively impact our ability to sell our products in a competitive environment, resulting in lower revenues, gross margins and earnings.

To reduce the cost of installed solar systems, as compared against the current cost, we will have to achieve cost savings across the entire value chain from designing to manufacturing to distributing to selling and ultimately to installing solar systems. We have identified specific areas of potential savings and are pursuing targeted goals. However, such cost savings are especially dependent upon factors outside of our direct control, including the cost of raw materials, the cost of both manufacturing and installation labor, and the cost of financing systems. If we are unsuccessful in our efforts to lower the cost of installed solar systems, our revenues, gross margins and earnings may be negatively impacted.

Management has identified material weaknesses in our internal control over financial reporting. Additionally, management may identify material weaknesses in the future that could adversely affect investor confidence, impair the value of our common stock and increase our cost of raising capital.

Management identified material weaknesses in our internal control over financial reporting and our Chief Executive Officer and our Chief Financial Officer concluded that our disclosure and internal controls and procedures were not effective at a reasonable assurance level as of December 31, 2013. There can be no assurance as to how quickly or effectively our remediation steps will remediate the material weakness in our internal control over financial reporting or that additional material weaknesses will not be identified in the future.

Any failure to remedy additional deficiencies in our internal control over financial reporting that may be discovered in the future or to implement new or improved controls, or difficulties encountered in the implementation of such controls, could harm our operating results, cause us to fail to meet our reporting obligations or result in material misstatements in our financial statements. Any such failure could, in turn, affect the future ability of our management to certify that our internal control over our financial reporting is effective. Inferior internal control over financial reporting could also subject us to the scrutiny of the SEC and other regulatory bodies which could cause investors to lose confidence in our reported financial information and could subject us to civil or criminal penalties or shareholder litigation, which could have an adverse effect on the trading price of our common stock.

In addition, if we or our independent registered public accounting firm identify additional deficiencies in our internal control over financial reporting, the disclosure of that fact, even if quickly remedied, could reduce the market’s confidence in our financial statements and harm our share price. Furthermore, additional deficiencies could result in future non-compliance with Section 404 of the Sarbanes-Oxley Act of 2002. Such non-compliance could subject us to a variety of administrative sanctions, including review by the SEC or other regulatory authorities.

We may not be able to retain, recruit and train adequate management personnel.

Our continued operations are dependent upon our ability to identify, recruit and retain adequate management personnel to perform certain jobs such as engineering of solar systems, developing and maintaining internet based platforms for monitoring of SEFs and producing and facilitating the shipment of materials necessary for the installation of SEFs. We require trained graduates of varying levels and experience and a flexible work force of semi-skilled operators.

Natural disasters and other events outside our control can disrupt our business.

Our business and financial results may be affected by certain events that we cannot anticipate or that are beyond our control, such as natural or man-made disasters, national emergencies, significant labor strikes, work stoppages, political unrest, war or terrorist activities that could curtail production at our facilities and cause delayed deliveries and canceled orders. In addition, we purchase components, raw materials and other services from numerous suppliers, and even if our facilities were not directly affected by such events, we could be affected by interruptions at such suppliers. Such suppliers may be less likely than our own facilities to be able to quickly recover from such events and may be subject to additional risks such as financial problems that limit their ability to conduct their operations. We cannot assure you that we will have insurance to adequately compensate us for any of these events.

Risks Related to Our International Operations

Concerns regarding the European debt crisis and market perceptions concerning the instability of the Euro could adversely affect the Company’s business, results of operations and financing.

Concerns persist regarding the debt burden of certain Eurozone countries and their ability to meet future financial obligations, the overall stability of the Euro and the suitability of the Euro as a single currency given the diverse economic and political circumstances in individual Eurozone countries. These concerns, or market perceptions concerning these and related issues, could adversely affect the value of the Company’s Euro-denominated assets and obligations and lead to future economic slowdowns.

We face risks associated with international trade and currency exchange.

We transact business in a variety of currencies, including the U.S. dollar, the Chinese Yuan Renminbi (“RMB”), and the Euro. We make all sales in both U.S. dollars and the Euro and we incur operating expenses in RMB and in Euros. Changes in exchange rates would affect the value of deposits of currencies we hold. Fluctuations in exchange rates may affect product demand and may adversely affect our profitability in U.S. dollars to the extent the price of our solar modules and cost of raw materials, labor, and equipment is denominated in a foreign currency. We do not currently hedge against our exposure to currency risk described above.

Changes in the U.S. Federal and international tax law regarding foreign earnings could materially affect our future results.

There have been proposals to change U.S. tax laws that would significantly impact how U.S. corporations are taxed on foreign earnings. We earn a substantial portion of our income in foreign countries. Although we cannot predict whether or in what form any of these proposals might be enacted into law, if adopted they could have a material adverse impact on our liquidity, results of operations, financial condition and cash flows.

Risks Related to our Common Stock

LDK controls us and may have conflicts of interest with other shareholders in the future.

LDK owns approximately 71% of our common stock on an as converted, fully-diluted basis. As a result, LDK will have significant control of the election of our directors and may influence our corporate and management policies. LDK also has sufficient voting power to amend our organizational documents. The interests of LDK may not coincide with the interests of other holders of our common stock. LDK may also pursue, for its own account, acquisition opportunities that may be complementary to our business, and as a result, those acquisition opportunities may not be available to us. So long as LDK continues to own a significant amount of the outstanding shares of our common stock, it will continue to be able to strongly influence or effectively control our decisions, including potential mergers or acquisitions, asset sales and other significant corporate transactions. Although we will operate separately, there are no assurances that conflicts will not arise in the future.

We have not paid and are unlikely to pay cash dividends in the foreseeable future.

We have not paid any cash dividends on our common stock and may not pay cash dividends in the future. Instead, we intend to apply earnings, if any, to the expansion and development of the business. Thus, the liquidity of your investment is dependent upon active trading of our stock in the market.

Any future financings and subsequent registration of common stock for resale will result in a significant number of shares of our common stock available for sale, and such sales could depress our common stock price. Further, no assurances can be given that we will not issue additional shares which will have the effect of diluting the equity interest of current investors. Moreover, sales of a substantial number of shares of common stock in any future public market could adversely affect the market price of our common stock and make it more difficult to sell shares of common stock at times and prices that either you or we determine to be appropriate.

We have significant “equity overhang” which could adversely affect the market price of our common stock and impair our ability to raise additional capital through the sale of equity securities.

As of December 31, 2013, we had 198,214,456 shares of common stock outstanding. LDK holds 141,517,570 shares of common stock or approximately 71% of total common stock outstanding. The possibility that substantial amounts of our outstanding common stock may be sold by LDK or the perception that such sales could occur, often called “equity overhang“, could adversely affect the market price of our common stock and could impair our ability to raise additional capital through the sale of equity securities in the future.

The preparation of our consolidated financial statements in accordance with U.S. generally accepted accounting principles requires us to make estimates, judgments, and assumptions that may ultimately prove to be incorrect.

The accounting estimates and judgments that management must make in the ordinary course of business affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the periods presented. If the underlying estimates are ultimately proven to be incorrect, subsequent adjustments could have a material adverse effect on our operating results for the period or periods in which the change is identified.

Our shareholders may experience future dilution.

Our charter permits our board of directors, without shareholder approval, to authorize shares of preferred stock. The board of directors may classify or reclassify any preferred stock to set the preferences, rights and other terms of the classified or reclassified shares, including the issuance of shares of preferred stock that have preference rights over the common stock with respect to dividends, liquidation, voting and other matters or shares of common stock having special voting rights. Further, substantially all shares of common stock for which our outstanding stock options are exercisable are, once they have been purchased, eligible for immediate sale in the public market.

The issuance of additional shares of our capital stock or the exercise of stock options or warrants could be substantially dilutive to your shares and may negatively affect the market price of our common stock.

ITEM 1B     UNRESOLVED STAFF COMMENTS

None.

ITEM 2          PROPERTIES

Our corporate headquarters are located in Roseville, California in an office space of 2,797 square feet which is under a one year lease that expires in July 2014. We occupy approximately 4,000 square feet of office space in San Francisco, California, for financial reporting, legal and business development, under a lease that expires in January 2017. The Company retains 1,680 square feet of warehouse space in Rocklin, California under a lease that expires in July 2017.

ITEM 3          LEGAL PROCEEDINGS

Except as set forth below, we are not a party to any pending legal proceeding. We are not aware of any pending legal proceeding to which any of our officers, directors, or any beneficial holders of 5% or more of our voting securities are a party that may have a material adverse effect to the Company’s business and consolidated financial position, results of operations or cash flows.

In November 2013, the board of directors of SGT approved a voluntary plan for liquidation. On December 30, 2013, the board of directors of SGT appointed a liquidator. Under Italian regulations, the liquidation process is controlled and carried out by the liquidator and the Company has no ability to exercise influence over SGT. SGT currently has insufficient funds to fund the SGT liquidation process. In the event SGT does not receive additional funds needed to proceed with the liquidation, SGT will likely be forced to file for bankruptcy protection. From time to time, we also are involved in various other legal and regulatory proceedings arising in the normal course of business. While we cannot predict the occurrence or outcome of these proceedings with certainty, we do 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.

ITEM 7 — MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion highlights what we believe are the principal factors that have affected our financial condition and results of operations, as well as our liquidity and capital resources for the periods described. This discussion should be read in conjunction with our financial statements and related notes appearing elsewhere in this Annual Report. This discussion contains “forward-looking statements“, which can be identified by the use of words such as “expects“, “plans“, “will“, “may“, “anticipates“, “believes“, “should“, “intends“, “estimates” and other words of similar meaning. These forward-looking statements are subject to risks and uncertainties that may cause actual results to differ materially from those expressed or implied by these forward-looking statements. Such risks and uncertainties include, without limitation, the risks described in Part I on page 4 of this Annual Report, and the risks described in Item 1A, Page 7 above.

The following discussion is presented on a consolidated basis, and analyzes our financial condition and results of operations for the years ended December 31, 2013 and 2012.

Unless the context indicates or suggests otherwise reference to “we”, “our”, “us” and the “Company” in this section refers to the consolidated operations of Solar Power, Inc.

Overview

Solar Power, Inc. and its subsidiaries (collectively the “Company”) is a global solar energy facility (“SEF”) developer offering high-quality, low-cost distributed generation and utility-scale SEF development services. Primarily, we partner with developers around the world who hold large portfolios of SEF projects for whom we serve as co-developer and engineering, procurement and construction (“EPC”) contractor. In addition to building SEFs using products manufactured by LDK Solar Co., Ltd. (“LDK”), our parent company, we also sell solar modules and balance of system components manufactured by third party vendors to other integrators in the U.S., Asian, and European markets. In addition to designing, engineering and constructing large-scale SEFs, we also provide long-term operations and maintenance (“O&M”) services through our proprietary O&M program SPIGuardian. This service program provides a comprehensive suite of services that engage upon a facility’s commissioning to provide performance monitoring, system reporting, preventative maintenance and full warranty support over the anticipated life of the SEF. While we still consider our O&M services to be within our core competencies, we have obtained third party outsourcing for these services to assist in the reduction of operating expenses.

On March 31, 2011, LDK Solar Co., Ltd. (“LDK”) obtained a controlling interest in Solar Power, Inc. by making a significant investment in our business that provided working capital and broader relationships that allowed us to more aggressively pursue commercial and utility projects globally. At December 31, 2013, LDK owns approximately 71% of the Company’s outstanding Common Stock. LDK’s modules have been used in the majority of the systems we produce; however, we maintain relationships with other module manufacturers when circumstances call for an alternative to LDK’s line of modules. In February 2014, LDK announced that LDK made a filing with the court for the appointment of joint provisional liquidators in connection with its plans to resolve its offshore liquidity issues. See Note 2 — Going Concern Considerations and Management’s Plan of the Notes of the Consolidated Financial Statements for further discussion related to the accounts payables with LDK.

Critical Accounting Policies and Estimates

Principles of Consolidation — The Consolidated Financial Statements include the accounts of the Company and companies in which the Company has a controlling interest. Intercompany transactions have been eliminated. The equity method of accounting is used for investments in affiliates and other joint ventures over which the Company has significant influence but does not have effective control. Investments in affiliates in which the Company cannot exercise significant influence are accounted for on the cost method.

Management also evaluates whether an interest is a variable interest entity and whether the Company is the primary beneficiary. Consolidation is required if both of these criteria are met. The Company does not have any variable interest entities requiring consolidation.

If the entity is not considered a variable interest entity, it is treated as a voting interest entity, and the Company applies the guidance of ASC 810-20 – “Control of Partnerships and Similar Entities”, in determining whether the entity should be consolidated. The Company does not hold interests in any partnerships or similar entities requiring consolidation.

Equity Method – Investee companies that are not consolidated, but over which the Company exercises significant influence, are accounted for under the equity method of accounting. Whether or not the Company exercises significant influence with respect to an Investee depends on an evaluation of several factors, including, among others, representation on the Investee company’s board of directors and ownership level. Under the equity method of accounting, an Investee company’s accounts are not reflected within the Company’s Consolidated Balance Sheets and Statements of Operations; however, the Company’s share of the earnings or losses of the Investee company is reflected in the caption ““Equity loss—share of Investee company losses’’ in the Consolidated Statements of Operations since the activities of the investee are closely aligned with the operations of our business segment. The Company’s carrying value in an equity method Investee company is reflected in the caption ““Investment in affiliates’’ in the Company’s Consolidated Balance Sheets. We evaluate our equity method investments whenever events or changes in circumstance indicate that the carrying amounts of such investments may be impaired. If a decline in the value of an equity method investment is determined to be other than temporary, a loss is recorded in earnings in the current period. We determined the fair value of our investment in KDC Solar Mountain Creek Parent LLC (the “LLC”) was $7.5 million based on an income approach applying discounted cash flows to measure the fair value using a 10% discount rate. We also used a market approach by comparing the fair value to other similar sized MW photovoltaic solar electricity projects taking into consideration the expected time and cost to complete the project. As a result, we recorded a $7.5 million impairment charge in the Consolidated Statement of Operations during the year ended December 31, 2013. There were no earnings or losses recorded from our equity method investment.

Revenue recognition

Product sales — Revenue on product sales is recognized when there is evidence of an arrangement, title and risk of ownership have passed (generally upon delivery), the price to the buyer is fixed or determinable and collectability is reasonably assured. We make determination of our customer’s credit worthiness at the time we accept their initial order. For cable, wire and mechanical assembly sales, there are no formal customer acceptance requirements or further obligations related to our assembly services once we ship our products. Customers do not have a general right of return on products shipped therefore we make no provisions for returns.

Construction Contracts — Revenue on photovoltaic system construction contracts is generally recognized using the percentage of completion method of accounting, unless we cannot make reasonably dependable estimates of the costs to complete the contract or the contact value is not fixed, in which case we would use the completed contract method. At the end of each period, the Company measures the cost incurred on each project and compares the result against its estimated total costs at completion. The percent of cost incurred determines the amount of revenue to be recognized. Payment terms are generally defined by the contract and as a result may not match the timing of the costs incurred by the Company and the related recognition of revenue. Such differences are recorded as costs and estimated earnings in excess of billings on uncompleted contracts or billings in excess of costs and estimated earnings on uncompleted contracts. The Company determines its customer’s credit worthiness at the time the order is accepted. Sudden and unexpected changes in customer’s financial condition could put recoverability at risk.

The percentage-of-completion method requires the use of various estimates, including, among others, the extent of progress towards completion, contract revenues and contract completion costs. Contract revenues and contract costs to be recognized are dependent on the accuracy of estimates, including direct material and labor costs and those indirect costs related to contract performance, such as indirect labor, supplies, tools, repairs, and depreciation costs. We have a history of making reasonable estimates of the extent of progress towards completion, contract revenues and contract completion costs. However, due to uncertainties inherent in the estimation process, it is possible that actual contract revenues and completion costs may vary from estimates. Under the completed-contract method, contract costs are recorded to a construction in progress account and cash received is recorded to a liability account during the periods of construction. All revenues, costs, and profits are recognized in operations upon completion of the contract. A contract is considered complete and revenue recognized when all costs except insignificant items have been incurred and final acceptance has been received from the customer and receivables are deemed to be collectible. Provisions for estimated losses on uncompleted contracts, if any, are recognized in the period in which the loss first becomes probable and reasonably estimable.

The asset, “Costs and estimated earnings in excess of billings on uncompleted contracts” represents revenues recognized in excess of amounts billed. The liability, “Billings in excess of costs and estimated earnings on uncompleted contracts“, represents billings in excess of revenues recognized.

For those projects where the Company is considered to be the owner, the project is accounted for under the rules of real estate accounting. In the event of a sale, the method of revenue recognition is determined by considering the extent of the buyer’s initial and continuing investment and the nature and the extent of the Company’s continuing involvement. Generally, revenue is recognized at the time of title transfer if the buyer’s investment is sufficient to demonstrate a commitment to pay for the property and the Company does not have a substantial continuing involvement with the property. When continuing involvement is substantial and not temporary, the Company applies the financing method, whereby the asset remains on the balance sheet and the proceeds received are recorded as a financing obligation. When a sale is not recognized due to continuing involvement and the financing method is applied, the Company records revenue and expenses related to the underlying operations of the asset in the Company’s Consolidated Financial Statements.

For any arrangements containing multiple deliverables not covered under the revenue guidance for real estate or for long-term construction contracts, we analyze each activity within the sales arrangement to ensure that we adhere to the separation guidelines for multiple-element arrangements. We allocate revenue for any transactions involving multiple elements to each unit of accounting based on our best estimate of the selling price, and recognize revenue for each unit of accounting when the revenue recognition criteria have been met.

Inventories — Certain factors could impact the realizable value of our inventory, so we continually evaluate the recoverability based on assumptions about customer demand and market conditions. The evaluation may take into consideration historic usage, expected demand, anticipated sales price, product obsolescence, customer concentrations, product merchantability and other factors. The reserve or impairment is equal to the difference between the cost of inventory and the estimated market value based upon assumptions about future demand and market conditions. If actual market conditions are less favorable than those projected by management, inventory reserves or impairments may be required that could negatively impact our gross margin and operating results.

Inventories are stated at the lower of cost or market, determined by the first in first out cost method. Work-in-progress and finished goods inventories consist of raw materials, direct labor and overhead associated with the manufacturing process. Provisions are made for obsolete or slow-moving inventory based on management estimates. Inventories are impaired based on the difference between the cost of inventories and the net realizable value based upon estimates about future demand from customers and specific customer requirements on certain projects. Inventory impairment charges establish a new cost basis for inventory and charges are not subsequently reversed to income even if circumstances later suggest that increased carrying amounts are recoverable.

Stock based compensation — The Company measures the stock-based compensation expense of share-based compensation arrangements based on the grant-date fair value and recognizes the costs in the financial statements over the employee requisite service period.

Determining the appropriate fair value model and calculating the fair value of share-based payment awards require the input of highly subjective assumptions, including the expected life of the share-based payment awards and stock price volatility. The assumptions used in calculating the fair value of share-based payment awards represent management’s best estimates, but these estimates involve inherent uncertainties and the application of management judgment. As a result, if factors change and we use different assumptions, our stock-based compensation expense could be materially different in the future. In addition, we are required to estimate the expected forfeiture rate and only recognize expense for those shares expected to vest. If our actual forfeiture rate is materially different from our estimate, the stock-based compensation expense could be significantly different from what we have recorded in the current period.

Allowance for doubtful accounts — The Company regularly monitors and assesses the risk of not collecting amounts owed to the Company 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. It requires the Company to make significant estimates and changes in facts and circumstances could result in material changes in the allowance for doubtful accounts.

Income taxes — The Company accounts for income taxes under the asset and liability method. Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting and tax reporting bases of assets and liabilities and are measured using enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse. Realization of deferred tax assets is dependent upon the weight of available evidence, including expected future earnings. A valuation allowance is recognized if it is more likely than not that some portion, or all, of a deferred tax asset will not be realized. Should we determine that we would be able to realize deferred tax assets in the future in excess of the net recorded amount, we would record an adjustment to the deferred tax asset valuation allowance. This adjustment would increase income in the period such determination is made.

Profit from non-U.S. activities is subject to local country taxes but not subject to U.S. tax until repatriated to the U.S. It is our intention to permanently reinvest these earnings outside the U.S. The calculation of tax liabilities involves dealing with uncertainties in the application of complex global tax regulations. We recognize potential liabilities for anticipated tax audit issues in the U.S. and other tax jurisdictions based on our estimate of whether, and the extent to which, additional taxes will more likely than not be due. If payment of these amounts ultimately proves to be unnecessary, the reversal of the liabilities may result in tax benefits being recognized in the period when we determine the liabilities are no longer necessary. If the estimate of tax liabilities proves to be less than the ultimate tax assessment, a further charge to expense may result.

The Company recognizes uncertain tax positions in its financial statements when it concludes that a tax position is more likely than not to be sustained upon examination based solely on its technical merits. Only after a tax position passes the first step of recognition will measurement be required. Under the measurement step, the tax benefit is measured as the largest amount of benefit that is more likely than not to be realized upon effective settlement. This is determined on a cumulative probability basis.

Recent Accounting Pronouncements

In July 2013, the FASB issued ASU 2013-11, Income Taxes—Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, which provides that an unrecognized tax benefit, or a portion thereof, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except to the extent that a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date to settle any additional income taxes that would result from disallowance of a tax position, or the tax law does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, then the unrecognized tax benefit should be presented as a liability. These changes become effective for the Company on January 1, 2014. Management does not expect the adoption of these changes to have a material impact on the Consolidated Financial Statements.

Results of Operations

Comparison of the year ended December 31, 2013 to the year ended December 31, 2012

Net sales — Net sales were $42.6 million and $100.0 million for the year ended December 31, 2013 and 2012, respectively, a decrease of $57.4 million, or 57.4%. Included in net sales for the year ended December 31, 2012 were related party sales to LDK, North Palm Springs Investments, LLC (“NPSLLC”), a wholly owned subsidiary of LDK Solar USA, Inc., and Terrasol of $35.5 million, primarily consisting of solar development project costs. The decrease in net sales for the year ended December 31, 2013 over the comparative period was primarily due to a decline in utility-scale solar projects in the U.S. We expect that net sales will remain consistent with year 2013 levels before ramping up again in the future as new project development is on hold while existing projects in process are completed and collections are achieved to provide further working capital for any new projects. Absent third party debt financing for project construction, future development will be dependent on internal cash flow.

Sales, marketing and customer service expense — Sales, marketing and customer service expenses were $2.1 million (4.8% of net sales) and $10.6 million (10.6% of net sales) for the years ended December 31, 2013 and 2012, respectively, a decrease of $8.6 million, or 80.7%. The decrease in sales, marketing and customer service expense for the year ended December 31, 2013 over the comparative period was primarily due to decreases in commission expense of $4.6 million, write-offs of $1.3 million related to non-refundable land deposit for certain solar projects in year 2012, which were reassessed and determined to no longer be viable for development, professional service of $0.6 million and personnel-related costs of $1.5 million. We expect that sales, marketing and customer service expenses, specifically personnel-related costs and commission expense, will remain consistent with year 2013 levels before ramping in-line with increases in net sales, as noted above.

Engineering, design and product management expense — Engineering, design and product management expenses were $1.8 million (4.1% of net sales) and $2.6 million (2.6% of net sales) for the years ended December 31, 2013 and 2012, respectively, an decrease of $0.8 million, or 33.2%. The decrease in engineering, design and product management costs for the year ended December 31, 2013 over the comparative period was primarily due to a decrease in consulting and personnel-related costs of $0.8 million. We expect these expenses to decline due to lower personnel-related costs in connection with our recent decisions to outsource design and engineering services.

Impairment charge — For the year ended December 31, 2013, no impairment of goodwill was recorded.

In December 2013 we entered into an exchange and release agreement with KDC and agreed to exchange our $15.0 million note receivable due to us from KDC under the EPC agreement for construction of the Mountain Creek Project in exchange for a 64.50% limited ownership interest in KDC Solar Mountain Creek Parent LLC (the “LLC”). As a result of this transaction, we determined the fair value of our investment in the LLC was $7.5 million based on an income approach applying discounted cash flows to measure the fair value using a 10% discount rate. We also used a market approach by comparing the fair value to other similar sized MW photovoltaic solar electricity projects taking into consideration the expected time and cost to complete the project. As a result, we recorded a $7.5 million impairment charge during the three months ended December 31, 2013.

During the three months ended September 30, 2012, due primarily to the recent reduction in the Company’s market capitalization, our market value was significantly below our book value, thus triggering an impairment analysis. As a result of this analysis, we recorded a goodwill impairment charge of $5.2 million. As such, the balance of goodwill as of December 31, 2012 was zero.

During the three months ended December 31, 2012, we determined that the carrying value of certain intangible assets related to customer relationships in our former cable, wire and mechanical assemblies business was no longer recoverable and therefore recognized an impairment loss of $0.1 million.

During the second quarter of 2012, we recorded an impairment charge of $0.7 million to reduce the carrying amount of the asset held for sale to the revised estimate of fair value less cost to sell. During the second quarter of 2012, subsequent to the impairment, this asset was sold to a related party.

Interest expense — Interest expense was $4.3 million and $4.1 million, respectively, for the years ended December 31, 2013 and 2012. The increase in interest expense of $0.2 million, or 6.3%, for the year ended December 31, 2013, over the comparative period was due to an increase in the interest rate of the line of credit from Cathay Bank which offset by repayment of principal balance. We expect that interest expense will continue to fluctuate in future periods depending on the utilization of debt financing in our operations.

Interest income — Interest income was $1.7 million and $2.5 million for the years ended December 31, 2013 and 2012, respectively. The decrease in interest income of approximately $0.8 million over the comparative period was due to the collection notes receivable for certain EPC contracts between the customers and the Company. We expect that we will continue to earn interest income at similar levels in the future until the notes are repaid by the customers. We do not expect to lend to new customers in the future, as such interest income is expected to fluctuate depending on the principal balance of the currently outstanding notes receivable.

Liquidity

A summary of the sources and uses of cash and cash equivalents is as follows:

As of December 31, 2013 and 2012, we had $1.0 million and $17.8 million, respectively, in cash and cash equivalents.

ITEM 9A.     CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our executive management is responsible for establishing and maintaining a system of disclosure controls and procedures (as defined in Rule 13a-15 and 15d-15 under the Securities Exchange Act of 1934 (the “Exchange Act”)) designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Exchange Act is accumulated and communicated to the issuer’s management, including its principal executive officer and principal financial officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Our executive management concluded that, because of the material weaknesses in our internal control over financial reporting discussed below, our disclosure controls and procedures were not effective as of December 31, 2013. Notwithstanding the material weakness discussed below, our executive management has concluded that the consolidated financial statements included in this Form 10-K present fairly, in all material respects, our financial position, results of operations and cash flows for the periods presented in conformity with accounting principles generally accepted in the United States.

Management’s Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). Our internal control over financial reporting is a process designed by, or under the supervision of, our Chief Executive Officer and Chief Financial Officer, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Internal control over financial reporting includes those policies and procedures which (a) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (b) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (c) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the financial statements.

Management, including our Chief Executive Officer and Chief Financial Officer, assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2013. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in the 1992 Internal Control-Integrated Framework. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company’s annual or interim financial statements will not be prevented or detected on a timely basis. Based on management’s assessment, including consideration of the control deficiencies discussed below, management has concluded that the Company’s internal control over financial reporting was not effective as of December 31, 2013, due to the fact that there were material weaknesses in its internal control over financial reporting.

This annual report does not include an attestation report of the Company’s registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by the Company’s registered public accounting firm pursuant to rules of the Securities and Exchange Commission that permit the Company (non-accelerated filer) to provide only management’s report in this annual report.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

1.            Description of Business and Basis of Presentation

Description of Business

Solar Power, Inc. and its subsidiaries (collectively the “Company”) consist of the combination of the legacy reporting entity Solar Power, Inc. and Solar Green Technology S.p.A. (“SGT”) and their respective subsidiaries. Refer to Note 5 and 6 for further details of the accounting impact of the SGT acquisition and deconsolidation.

The Company is a global solar energy facility (“SEF”) developer offering our own brand of high-quality, low-cost distributed generation and utility-scale SEF development services. Primarily, the Company partners with developers around the world who hold large portfolios of SEF projects for whom it serves as co-developer and engineering, procurement and construction (“EPC”) contractor. The Company builds three basic types of SEFs: rooftop systems, ground mounted systems, and parking shade structure systems. The Company’s proprietary SkyMount® commercial rooftop racking system and its custom parking shade structures are procured through contract manufacturers and built to the Company’s design specifications are still being used for current projects under development.

In addition to designing, engineering and constructing large-scale SEFs, the Company also provides long-term operations and maintenance (“O&M”) services through our proprietary O&M program SPIGuardianTM. This service program provides a comprehensive suite of services that engage upon a facility’s commissioning to provide performance monitoring, system reporting, preventative maintenance and full warranty support over the anticipated life of the SEF. While the Company still considers its O&M services to be within its core competencies, it has obtained third party outsourcing for these services to assist in the reduction of operating expenses.

On January 5, 2011, the Company entered into a stock purchase agreement with LDK Solar Co., Ltd. (“LDK”), a vertically integrated solar wafer, cell and solar module manufacturer. On March 31, 2011, LDK obtained a controlling interest in Solar Power, Inc. by making a significant investment in our business that provided working capital and broader relationships that allowed us to more aggressively pursue commercial and utility projects globally. LDK’s modules are used in the majority of the systems the Company produces; however, it maintains relationships with other module manufacturers when circumstances call for an alternative to LDK’s line of modules.

Basis of Presentation

The Consolidated Financial Statements of the Company are prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and require management to make certain judgments, estimates and assumptions. These may affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements. They also may affect the reported amounts of revenues and expenses during the reporting period. Key estimates used in the preparation of our financial statements include: contract percentage-of-completion and cost estimates, construction in progress, allowance for doubtful accounts, stock-based compensation, warranty reserve, deferred taxes, valuation of inventory, and valuation of other intangible assets. Actual results could differ from those estimates upon subsequent resolution of identified matters.

The accompanying Consolidated Financial Statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The realization of assets and the satisfaction of liabilities in the normal course of business are dependent on, among other things, the Company’s ability to operate profitably, to generate cash flows from operations, and to pursue financing arrangements to support its working capital requirements.

NOTE 2 – GOING CONCERN CONSIDERATIONS AND MANAGEMENT’S PLAN

We are experiencing the following risks and uncertainties in the business:

3.            Summary of Significant Accounting Policies

Principles of Consolidation – The Consolidated Financial Statements include the accounts of the Company and companies in which the Company has a controlling interest. Intercompany transactions have been eliminated. The equity method of accounting is used for investments in affiliates and other joint ventures over which the Company has significant influence but does not have effective control. Investments in affiliates in which the Company cannot exercise significant influence are accounted for on the cost method.

Management also evaluates whether an interest is a variable interest entity and whether the Company is the primary beneficiary. Consolidation is required if both of these criteria are met. The Company does not have any variable interest entities requiring consolidation.

If the entity is not considered a variable interest entity, it is treated as a voting interest entity, and the Company applies the guidance of ASC 810-20 – “Control of Partnerships and Similar Entities”, in determining whether the entity should be consolidated. The Company does not hold interests in any partnerships or similar entities requiring consolidation.

Cash and cash equivalents — Cash and cash equivalents include cash on hand, cash accounts, interest bearing savings accounts and all highly liquid investments with original maturities of three months or less, when purchased.

Inventories — Inventories are carried at the lower of cost or market, determined by the first in first out cost method. Work-in-progress and finished goods inventories consist of raw materials, direct labor and overhead associated with the manufacturing process. Provisions are made for obsolete or slow-moving inventories based on management estimates. Inventories are impaired based on the difference between the cost of inventories and the net realizable value based upon estimates about future demand from customers and specific customer requirements on certain projects. Inventory impairment charges establish a new cost basis for inventory and charges are not subsequently reversed to income even if circumstances later suggest that increased carrying amounts are recoverable. Inventory consisted of finished goods at December 31, 2013 and 2012.

Property, plant and equipment — Property, plant and equipment are recorded at cost, including the cost of improvements. Maintenance and repairs are charged to expense as incurred. Depreciation is recorded on the straight-line method based on the estimated useful lives of the assets as follows:

Impairment of long-lived assets — Long-lived assets, such as property, plant and equipment and intangible assets other than goodwill, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated undiscounted future cash flows, an impairment charge is recognized by the amount by which the carrying value of the asset exceeds the fair value of the asset. Assets to be disposed of are separately presented in the balance sheet and reported at the lower of the carrying value or fair value less costs to sell, and are no longer depreciated.

Intangible assets other than goodwill — Intangible assets consist of patents and customer relationships. Amortization is recorded on the straight-line method based on the estimated useful lives of the assets.

Revenue recognition

Product sales — Revenue on product sales is recognized when there is evidence of an arrangement, title and risk of ownership have passed (generally upon delivery), the price to the buyer is fixed or determinable and collectability is reasonably assured. The Company makes determination of our customer’s credit worthiness at the time it accepts their initial order. For cable, wire and mechanical assembly sales, there are no formal customer acceptance requirements or further obligations related to our assembly services once the Company ships its products. Customers do not have a general right of return on products shipped therefore the Company makes no provisions for returns.

Construction contracts — Revenue on photovoltaic system construction contracts is generally recognized using the percentage-of-completion method of accounting, unless we cannot make reasonably dependable estimates of the costs to complete the contract or the contact value is not fixed, in which case we would use the completed contract method. At the end of each period, the Company measures the cost incurred on each project and compares the result against its estimated total costs at completion. The percent of cost incurred determines the amount of revenue to be recognized. Payment terms are generally defined by the contract and as a result may not match the timing of the costs incurred by the Company and the related recognition of revenue. Such differences are recorded as costs and estimated earnings in excess of billings on uncompleted contracts (an asset account) or billings in excess of costs and estimated earnings on uncompleted contracts (a liability account). For the years ended December 31, 2013 and 2012, nil and $10.8 million of progress payments have been netted against contracts costs disclosed in the account costs and estimated earnings in excess of billings on uncompleted contracts. The Company determines its customer’s credit worthiness at the time the order is accepted. Sudden and unexpected changes in customer’s financial condition could put recoverability at risk.

The percentage-of-completion method requires the use of various estimates, including, among others, the extent of progress towards completion, contract revenues and contract completion costs. Contract revenues and contract costs to be recognized are dependent on the accuracy of estimates, including direct material and labor costs and those indirect costs related to contract performance, such as indirect labor, supplies, tools, repairs, and depreciation costs. The Company has a history of making reasonable estimates of the extent of progress towards completion, contract revenues and contract completion costs. However, due to uncertainties inherent in the estimation process, it is possible that actual contract revenues and completion costs may vary from estimates. Under the completed-contract method, contract costs are recorded to a construction in progress account and cash received are recorded to a liability account during the periods of construction. All revenues, costs, and profits are recognized in operations upon completion of the contract. A contract is considered complete and revenue recognized when all costs except insignificant items have been incurred and final acceptance has been received from the customer and receivables are deemed to be collectible. Provisions for estimated losses on uncompleted contracts, if any, are recognized in the period in which the loss first becomes probable and reasonably estimable.

For those projects where the Company is considered to be the owner, the project is accounted for under the rules of real estate accounting. In the event of a sale, the method of revenue recognition is determined by considering the extent of the buyer’s initial and continuing investment and the nature and the extent of the Company’s continuing involvement. Generally, revenue is recognized at the time of title transfer if the buyer’s investment is sufficient to demonstrate a commitment to pay for the property and the Company does not have a substantial continuing involvement with the property. When continuing involvement is substantial and not temporary, the Company applies the financing method, whereby the asset remains on the balance sheet and the proceeds received are recorded as a financing obligation. When a sale is not recognized due to continuing involvement and the financing method is applied, the Company records revenue and expenses related to the underlying operations of the asset in the Company’s Consolidated Financial Statements.

For any arrangements containing multiple deliverables, the Company analyzes each activity within the sales arrangement to ensure that it adheres to the separation guidelines for multiple-element arrangements.  The Company allocates revenue for any transactions involving multiple elements to each unit of accounting based on its best estimate of the selling price, and recognize revenue for each unit of accounting when the revenue recognition criteria have been met.

Accounts receivable — The Company grants open 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.

Allowance for doubtful accounts — 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. It requires the Company to make significant estimates, and changes in facts and circumstances could result in material changes in the allowance for doubtful accounts. Changes in allowance for doubtful accounts are as follows (in thousands):

Related Party Transactions — Products are bought from and sold to related parties at negotiated arms-length prices between the two parties.

Shipping and handling cost — Shipping and handling costs related to the delivery of finished goods are included in cost of goods sold. During the years ended December 31, 2013 and 2012, shipping and handling costs recorded in cost of goods sold were $0.1 million and $0.6 million, respectively.

Advertising costs — Costs for newspaper, television, radio, and other media and design are expensed as incurred. The Company expenses the production costs of advertising the first time the advertising takes place. The costs for this type of advertising were $0.1 million and $0.1 million during the years ended December 31, 2013 and 2012, respectively.

Stock-based compensation — The Company measures the stock-based compensation costs of share-based compensation arrangements based on the grant-date fair value and generally recognizes the costs in the financial statements over the employee requisite service period. For further details, see Note 13 — Stock-based compensation.

Income taxes — The Company accounts for income taxes under the asset and liability method. Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting and tax reporting bases of assets and liabilities and are measured using enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse. Realization of deferred tax assets is dependent upon future taxable income. A valuation allowance is recognized if it is more likely than not that some portion, or all of a deferred tax asset will not be realized based on the weight of available evidence, including expected future earnings.

The Company recognizes the benefit of uncertain tax positions in its financial statements when it concludes that a tax position is more likely than not to be sustained upon examination based solely on its technical merits. Only after a tax position passes the first step of recognition will measurement be required. Under the measurement step, the tax benefit is measured as the largest amount of benefit that is more likely than not to be realized upon effective settlement. This is determined on a cumulative probability basis.

The Company elects to accrue any interest or penalties related to its uncertain tax positions as part of its income tax expense.

Foreign Currency — The Consolidated Financial Statements are presented in our reporting currency, U.S. dollars. The functional currency for the subsidiaries in Italy is the Euro. The functional currency for the subsidiaries in The People’s Republic of China is the Renminbi. Accordingly, balance sheets of the foreign subsidiaries are translated into U.S. dollars using the exchange rate in effect at the balance sheet date. Revenues and expenses are translated using the average exchange rates in effect during the period. Translation differences are recorded in accumulated other comprehensive (loss) income as foreign currency translation. Gains or losses on transactions denominated in a currency other than the subsidiaries’ functional currency which arises as a result of changes in foreign exchange rates are recorded as foreign exchange gain or loss in the statements of operations.

Post-retirement and post-employment benefits — The Company’s subsidiaries which are located in the People’s Republic of China and Italy contribute to a state pension scheme on behalf of its employees. The Company recorded $0.1million and $0.6 million in expense related to its pension contributions for the years ended December 31, 2013 and 2012, respectively. Neither the Company nor its subsidiaries provide any other post-retirement or post-employment benefits.

4.            Recently Adopted and Recently Issued Accounting Guidance

In March 2013, FASB issued ASU No. 2013-05, Foreign Currency Matters—Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity, which allows an entity to release cumulative translation adjustment into net income when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity. The Company adopted these changes on January 1, 2013. The additional disclosures required by this ASU are included in Note 6.

In April 2013, the FASB issued ASU 2013-07, Liquidation Basis of Accounting, which require an entity to use the liquidation basis of accounting to present its financial statements when it determines that liquidation is imminent, unless the liquidation is the same as that under the plan specified in an entity’s governing documents created at its inception. Liquidation is imminent when the likelihood is remote that the entity will return from liquidation and either (a) a plan for liquidation is approved by the person or persons with the authority to make such a plan effective and the likelihood is remote that the execution of the plan will be blocked by other parties or (b) a plan for liquidation is being imposed by other forces (for example, involuntary bankruptcy). These changes become effective for the Company on January 1, 2014. Entities should apply the requirements prospectively from the day that liquidation becomes imminent. Management is currently evaluating the impact of this amendment on the Consolidated Financial Statements.

In July 2013, the FASB issued ASU 2013-11, Income Taxes—Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, which provides that an unrecognized tax benefit, or a portion thereof, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except to the extent that a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date to settle any additional income taxes that would result from disallowance of a tax position, or the tax law does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, then the unrecognized tax benefit should be presented as a liability. These changes become effective for the Company on January 1, 2014. Management does not expect the adoption of these changes to have a material impact on the Consolidated Financial Statements.

5.            Acquisition of Solar Green Technology

On June 27, 2012, Solar Power, Inc. entered into an Acquisition and Stock Purchase Agreement dated as of June 25, 2012 (the “SGT Agreement”) with the shareholders of SGT, an Italian-based limited liability company. Under the SGT Agreement, Solar Power, Inc. acquired 100% of the issued and outstanding shares of SGT from SGT shareholders in exchange for 5.0 million Euros (approximately $6.3 million U.S. Dollars) payable in cash and common stock of the Company (the “Purchase Price”). The shareholders of SGT consisted of LDK Solar Europe Holding S.A (“LDK Europe”) and the two founders of SGT. LDK Europe, through its 70% ownership of the outstanding common stock of SGT, controlled SGT prior to the close of the transaction. LDK Europe is a wholly owned subsidiary of LDK, which owned approximately 71% of the issued and outstanding common stock of the Company prior to and after the date of the acquisition of SGT. In July 2012, the Company issued 9,771,223 shares of its Common Stock to LDK Europe and 1,814,655 shares of its Common Stock to each of the two founders of SGT. In addition, the Company agreed to pay each of the two founders 100,000 Euros in cash, the payments of which were made in July 2012. The amount of shares of the Company’s Common Stock that were issued under the SGT Agreement were determined by calculating the amount of the Purchase Price payable to each shareholder divided by the daily volume-weighted average price of the Company’s Common Stock for each of the 90 trading days prior to June 11, 2012.

Because SGT and Solar Power, Inc. were under the common control of LDK as of the June 27, 2012 acquisition date, the acquisition is treated as a transaction between entities under common control. In accordance with ASC Topic 805, Business Combinations these financial statements reflect the combination of Solar Power, Inc. and SGT’s financial statements for all periods presented under which both entities were under the common control of LDK. The predecessor entity was determined to be SGT due to the fact that SGT was the first entity controlled by LDK. LDK obtained a controlling interest in SGT on July 10, 2009. LDK obtained a controlling interest in Solar Power, Inc. on March 31, 2011. As such, the Company recognized the assets and liabilities of SGT (the accounting receiving entity) at their historical carrying values in accordance with U.S. GAAP and recast the assets and liabilities of the legacy Solar Power, Inc. entity (the transferring entity) to reflect carrying value of the parent, LDK, which were stepped up to fair value on March 31, 2011 upon LDK obtaining a controlling interest in Solar Power, Inc. Refer to Note 11 —Goodwill and Other Intangible Assets for details of the balances carried by LDK now reflected in the Consolidated Financial Statements. Upon LDK acquiring its controlling interest in Solar Power, Inc. on March 31, 2011, the equity of the new reporting entity for the combined financial statements of Solar Power, Inc. and SGT reflects the Preferred and Common Stock of Solar Power, Inc. and associated additional paid-in capital and SGT’s retained earnings and foreign currency translation at March 31, 2011. Adjustments to eliminate the capital share accounts of SGT were recorded to additional paid-in capital.

6.            Deconsolidation of Solar Green Technology

In November 2013, the board of directors of SGT approved a voluntary plan for liquidation. On December 30, 2013, the board of directors of SGT appointed a liquidator. Under Italian regulations, the liquidation process is controlled and carried out by the liquidator and the Company has no ability to exercise influence over SGT. As a result of these actions, the Company deconsolidated SGT on December 30, 2013 when the Company ceased to have a controlling financial interest in SGT. The Company recognized a gain on deconsolidation of $3.5 million which was recognized in other income in the statement of operations as the liquidation is a run-off of operations. Additionally, the Company deconsolidated net liabilities owned by SGT to LDK of $2.0 million. As LDK is the Company’s parent company, this portion of the deconsolidation was treated as debt forgiveness and a capital transaction recorded as an increase to additional paid in capital.

The Components of the gain on deconsolidation are as follows (in thousands):

The fair value of the Company’s retained investment in SGT is zero at December 31, 2013. SGT will remain a related party of the Company.

7.            Balance Sheet Component

Accrued liabilities (in thousands):

8.            Accounts and Notes Receivable

During 2013, the Company recognized $13.9 million revenue under the completed-contract method and recorded a receivable of $8.8 million (originally denominated in euro’s) related to the sale of its Greece projects. Due to the delay in the customer receiving term financing from CDB, the receivable is currently being collected over a six year agreed upon payment schedule, plus variable interest. The difference of $5.1 million between revenue recognized and account receivable balance relates to prior payments received from the customer which had been recorded as a customer deposit within accrued liabilities. As of December 31, 2013, due to the extended collection period, $2.2 million of the accounts receivable is recorded as current and $6.6 million is recorded in accounts receivable, noncurrent. During the second quarter of 2013, the Company reclassified $5.9 million of existing accounts receivables from a second unrelated customer to noncurrent based on the expected collection period which is anticipated to exceed one year. As of December 31, 2013, the Company has $2.0 million recorded in accounts receivable, current and $5.8 million recorded in accounts receivable, noncurrent from this second customer.

The Company agreed to advance to customer KDC predevelopment and site acquisition costs related to the Imclone EPC agreement between KDC and the Company and recorded the amount as notes receivable. The terms of the EPC agreement require repayment of the advance upon final completion of the SEF, which was expected to occur in the first half of 2013 but is now expected to occur in the first half of 2014 as the project did not break ground until the second quarter of 2013. The advance bears interest at the rate of 5% per year that is payable at the time the principal is repaid. The advance and related interest was collected in full in December 2013 as KDC obtained term debt financing for the project in December 2013. As of December 31, 2013and 2012, the balance of the note receivable from this project was none and $7.0 million, respectively. These amounts are recorded in the current notes receivable.

During 2013 the Company issued a note receivable to KDC for one completed contract with 15 year payment terms which began on the commercial operations date which was April 2013. The note bears interest of LIBOR plus 460bps. If the customer obtains term debt financing for their project, the collection of the note receivable may be accelerated.  During 2013 the Company issued another note receivable to KDC for the Mountain Creek project that has not been completed. In December 2013, the Company entered into an exchange and release agreement with KDC and agreed to exchange this note receivable due in exchange for a 64.50% limited ownership interest in KDC Solar Mountain Creek Parent LLC (see Note 10). As of December 31, 2013 and 2012, the balance recorded in noncurrent notes receivable related to this customer was $13.6 million and none, respectively.

On April 27, 2012, the Company made a secured loan of $1.0 million to Solar Hub Utilities, LLC (“Solar Hub”), to be used for pre-development costs, and recorded the amount in the account notes receivable. On June 8, 2012, the Company agreed to advance Solar Hub up to $9.0 million under a new $9.0 million secured promissory note, which refinanced the original $1.0 million advance and bears a 6% annual interest rate. In March 2013, the interest was changed to a 10% annual interest rate in accordance with the Amended and Restated Secured Promissory Note. This note receivable is secured by the project assets. Repayment in full of all borrowed amounts was due on December 31, 2012 but, in March 2013, was extended to a new maturity date of July 1, 2014 in accordance with the Amended and Restated Secured Promissory Note. As of December 31, 2013 and 2012, the balance of the note receivable from Solar Hub was $8.4 million and $7.1 million, respectively.

9.            Property, Plant and Equipment

Property, plant and equipment consisted of the following (in thousands):

In 2009, Solar Power, Inc. capitalized a photovoltaic (“PV”) solar system relating to the Aerojet 1 solar development project along with the associated financing obligation, recorded under financing and capital lease obligations, net of current portion, in the Consolidated Balance Sheets. Due to certain guarantee arrangements as disclosed in Note 16— Commitments and Contingencies, the Company will continue to record this solar system in property, plant and equipment with its associated financing obligation in financing obligations as long as it maintains its continuing involvement with this project. The income and expenses relating to the underlying operation of the Aerojet 1 project are recorded in the Consolidated Statement of Operations.

During the year ended December 31, 2011, the Company’s subsidiary, SGT, completed construction of two SEFs, which was classified as held for sale as of December 31, 2011. In May 2012, SGT sold to and leased back the assets from a leasing company. The gross amount of assets recorded under the capital leases was $5.9 million, with accumulated depreciation of $0.2 million, as of December 31, 2012. The SEFs were classified as PV solar systems under capital leases, which were recorded in Financing and capital lease obligations, net of current portion, on the Consolidated Balance Sheet at December 31, 2012. The SEFs were removed from the Company’s Consolidated Balance Sheet in 2013 in connection with the Company’s deconsolidation of SGT.

Depreciation expense was $1.3 million and $1.1 million for the years ended December 31, 2013 and 2012, respectively.

10.          Investment in Affiliates

Prior to the exchange and release agreement, the Company accumulated $2.7 million of costs and estimated earnings in excess of billings on the uncompleted Mountain Creek project. As the costs and estimated earnings in excess of billings were not a part of the Company’s investment in the LLC, the Company recorded a $2.7 million provision for losses on contracts in the consolidated statement of operations for the year ended December 31, 2013 and reducing the costs and estimated earnings in excess of billings on the uncompleted contracts to $0 at December 31, 2013.

11.          Goodwill and Other Intangible Assets

Goodwill

The carrying value of goodwill was $5.2 million at December 31, 2011, all of which was allocated to the Company’s single reportable segment. Of this balance, $4.7 million reflected the balance of Solar Power, Inc. carried by its parent company, LDK, as required under the accounting guidelines for a transfer of an entity under common control (refer to Note 5— Acquisition of Solar Green Technology). The Company evaluated the carrying value of its goodwill at December 31, 2011, and determined that no impairment of goodwill was identified. During the three months ended September 30, 2012, due primarily to the recent reduction in the Company’s market capitalization, the Company’s market value was significantly below its book value, thus triggering an impairment analysis. As a result of this analysis, the Company recorded a goodwill impairment charge of $5.2 million. As a result, the balance of goodwill as of December 31, 2012 was zero.

Other Intangible Assets

During the three months ended December 31, 2012, the Company determined that the carrying value of certain intangible assets related to customer relationships were no longer recoverable based on a discrete evaluation of the nature of the intangible assets, incorporating the effect of the Company’s recent decision to no longer maintain the customer relationships. As a result, the Company recorded an impairment charge of $0.1 million on its Consolidated Statement of Operations for the year ended December 31, 2012. The balance of intangible assets as of December 31, 2013 and December 31, 2012 was $1.1 million and $1.7 million, respectively.

Other intangible assets consisted of the following (in thousands):

As of December 31, 2013, the estimated future amortization expense related to other intangible assets is as follows (in thousands):

12.          Stockholders’ (Deficit) Equity

Issuance of common stock

On June 8, 2012, the Company issued 400,000 shares of restricted Common Stock pursuant to the Company’s 2006 Equity Incentive Plan (defined below) as compensation to its non-employee directors. The fair value of the shares was $0.265 per share, the closing price of the Company’s Common Stock on June 12, 2012, the date of the grant. The shares vested on the date of grant.

In July 2012, the Company issued 9,771,223 shares of its Common Stock to LDK Europe, a wholly-owned subsidiary of LDK, and 1,814,655 of its Common Stock to each of the two founders of SGT pursuant to the SGT Acquisition and Stock Purchase Agreement as part of an aggregate purchase price of 5.0 million Euros (approximately $6.3 million in U.S. Dollars at June 30, 2012). For further discussion of the transaction, refer to Note 5 —Acquisition of Solar Green Technology.

Issuance of warrants to purchase common stock

On February 15, 2012, the Company’s Board of Directors approved the issuance of a warrant agreement for Cathay General Bancorp to purchase 300,000 shares of the Company’s Common Stock at $0.75 per share related to the credit facility entered into with Cathay Bank for an original aggregate principal amount of $9.0 million. The fair value of $0.29 per share was determined using the Black-Scholes-Merton model. Assumptions used in calculating fair value were as follows: a risk free interest rate of .38%, expected volatility of 103%, zero expected dividend yield, and an expected term of 3 years. The warrant expires on February 15, 2015 and is exercisable anytime within that period for an exercise price of $0.75 per share. The value of the warrant will be amortized over the remaining term of the associated credit facility through December 31, 2012. For the year ended December 31, 2012, $87,000 was amortized to interest expense.
