All statements contained in this Quarterly Report on Form 10-Q other than statements of historical fact, including statements regarding our future operating results and financial position, our business strategy and plans and our objectives for future operations, are forward-looking statements. The words “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “predict,” “project,” “potential,” ”seek,” “intend,” “could,” “would,” “should,” “expect,” “plan” and similar expressions are intended to identify forward-looking statements.
Forward-looking statements in this Quarterly Report on Form 10-Q include, but are not limited to, our plans and expectations regarding future financial results, expected operating results, business strategies, the sufficiency of our cash and our liquidity, projected costs and cost reductions, development of new products and improvements to our existing products, the impact of recently adopted accounting pronouncements, our manufacturing capacity and manufacturing costs, the adequacy of our agreements with our suppliers, legislative actions and regulatory compliance, competitive position, management’s plans and objectives for future operations, our ability to obtain financing, our ability to comply with debt covenants or cure defaults, if any, our ability to repay our obligations as they come due, trends in average selling prices, the success of our PPA Entities, expected capital expenditures, warranty matters, outcomes of litigation, our exposure to foreign exchange, interest and credit risk, general business and economic conditions in our markets, industry trends, the impact of changes in government incentives, risks related to privacy and data security, the likelihood of any impairment of project assets, long-lived assets and investments, trends in revenue, cost of revenue and gross profit (loss), trends in operating expenses including research and development expense, sales and marketing expense and general and administrative expense and expectations regarding these expenses as a percentage of revenue, future deployment of our Energy Servers, expansion into new markets, our ability to expand our business with our existing customers, our ability to increase efficiency of our product, our ability to decrease the cost of our product, our future operating results and financial position, our business strategy and plans and our objectives for future operations.

The outcome of the events described in these forward-looking statements is subject to risks, uncertainties and other factors including those discussed in ITEM 1A - Risk Factors and elsewhere in this Quarterly Report on Form 10-Q. Moreover, we operate in a very competitive and rapidly changing environment. New risks and uncertainties emerge from time to time and it is not possible for us to predict all risks and uncertainties or the extent to which any factor or combination of factors may cause actual results to differ materially from those contained in any forward-looking statements we may make in this Quarterly Report on Form 10-Q. We cannot assure you that the results, events and circumstances reflected in the forward-looking statements will be achieved or occur. Actual results, events or circumstances could differ materially and adversely from those described or anticipated in the forward-looking statements.

We undertake no obligation to update any forward-looking statements made in this Quarterly Report on Form 10-Q to reflect events or circumstances after the date of this Quarterly Report on Form 10-Q or to reflect new information or the occurrence of unanticipated events, except as required by law. We may not actually achieve the plans, intentions or expectations disclosed in our forward-looking statements and you should not place undue reliance on our forward-looking statements.

1. Nature of Business and Liquidity
Nature of Business
Bloom Energy Corporation (together with its subsidiaries, the Company or Bloom Energy) designs, manufacturesWe design, manufacture, sell and, sellsin certain cases, install solid-oxide fuel cell systems, or Energy Servers, for on-site power generation. The Company’sOur Energy Servers utilize an innovative fuel cell technology. The Energy Servers provide efficient energy generation with reduced operating costs and lower greenhouse gas emissions. By generating power where it is consumed, theour energy producing systems offer increased electrical reliability and improved energy security while providing a path to energy independence. The Company wasWe were originally incorporated in Delaware under the name of Ion America Corporation on January 18, 2001 and waswere renamed on September 16, 2006 to Bloom Energy Corporation. To date, substantially all of
Throughout this Quarterly Report on Form 10-Q, unless the Company’s revenue has been derived from customers based incontext otherwise requires, the United States.terms “Bloom Energy,” “we,” “us” and “our” refer to Bloom Energy Corporation and its consolidated subsidiaries.
Liquidity
The CompanyWe have incurred operating losses and negative cash flows from operations since itsour inception. The Company’sOur ability to achieve itsour long-term business objectives is dependent upon, among other things, raising additional capital, the acceptance of itsour products and attaining future profitability. Management believes that the CompanyWe believe we will be successful in raising additional financing from itsour stockholders or from other sources, in expanding operations and in gaining market share. In fact,For example, in July 2018, and subsequent to the date of the financial statements included in this Quarterly Report on Form 10-Q, the Companywe successfully completed an initial public stock offering (IPO)("IPO") with the sale of 20,700,000 shares of Class A common stock at a price of $15$15.00 per share, resulting in net cash proceeds of $284.3$282.3 million net of underwriting discounts, commissions and estimated offering costs. We believe that our existing cash and cash equivalents and short-term investments will be sufficient to meet our operating and capital cash flow requirements and other cash flow needs for at least the next 12 months from the date of this quarterly report on Form 10-Q. However, there can be no assurance that in the event the Company requireswe require additional financing, such financing will be available on terms which are favorable or at all.

2. Basis of Presentation and Summary of Significant Accounting Policies
Unaudited Interim Consolidated Financial Statements
TheWe have prepared the condensed consolidated financial statements included herein pursuant to the rules and regulations of the U.S. Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures normally included in the consolidated balance sheets as of June 30,March 31, 2019 and December 31, 2018,, the consolidated statements of operations, and the consolidated statements of comprehensive loss, for the threeconsolidated statements of convertible redeemable preferred stock, redeemable noncontrolling interest, stockholders' deficit and six months ended June 30, 2018,noncontrolling interest, and2017, the consolidated statements of cash flows for the sixthree months ended June 30, 2018March 31, 2019 and 2017 and the consolidated statements of convertible redeemable preferred stock and stockholders' deficit as of June 30, 2018, as well as other information disclosed in the accompanying notes are unaudited. The consolidated balance sheet as of December 31, 2017 and the consolidated statements of convertible redeemable preferred stock and stockholders' deficit as of December 31, 2017 was derived from the audited consolidated financial statements as of that date. The interim consolidated financial statements and the accompanying notes should be read in conjunction with the annual consolidated financial statements and the accompanying notes contained within the Company's Form S-1 filed with the Securities and Exchange Commission which was declared effective on July 24, 2018.
The Company's consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (US GAAP) for interim financial information and,as applied in the opinion of management, reflectUnited States ("U.S. GAAP") have been condensed or omitted pursuant to such rules and regulations. However, we believe that the disclosures herein are adequate to ensure the information presented is not misleading. These unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and the notes thereto included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018.
We believe that all necessary adjustments, which includeconsisted only of normal recurring adjustments, necessary for a fair statementitems, have been included in the accompanying financial statements to fairly state the results of the interim periods. The results of operations for the interim periods presented.presented are not necessarily indicative of the operating results to be expected for any subsequent interim period or for our fiscal year ending December 31, 2019.
Principles of Consolidation
These condensed consolidated financial statements reflect theour accounts and operations of the Company and those of itsour subsidiaries in which the Company haswe have a controlling financial interest. The Company usesWe use a qualitative approach in assessing the consolidation requirement for itseach of our variable interest entities, which the Company referswe refer to as our power purchase agreement entities (PPA Entities)("PPA Entities"). This approach focuses on determining whether the Company haswe have the power to direct thethose activities of the PPA Entities that most significantly affect the PPA Entities’their economic performance and whether the Company haswe have the obligation to absorb losses, or the right to receive benefits, that could potentially be significant to the PPA Entities. For all periods presented, the Company haswe have determined that it iswe are the primary beneficiary in all of its operational PPA Entities. The Company evaluates itsWe evaluate our relationships with the PPA Entities on an ongoing basis to ensure that itwe continues to be the primary beneficiary. All intercompany transactions and balances have been eliminated in consolidation. For additional information, see Note 12 - Power Purchase Agreement Programs.

Use of Estimates 
The preparation of condensed consolidated financial statements in conformity with USU.S. GAAP requires managementus to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and the accompanying notes. Significant estimates include assumptions used to compute the best estimate of selling-prices, (BESP), the fair value of lease and non-lease components such as estimated output, efficiency and residual value of the Energy Servers, estimates for inventory write-downs, estimates for future cash flows and the economic useful lives of property, plant and equipment, the valuation of other long-term assets, the valuation of certain accrued liabilities such as derivative valuations, estimates for accrued warranty and extended maintenance, and estimates for recapture of U.S. Treasury grants and similar grants, estimates for income taxes and deferred tax asset valuation allowances, warrant liabilities, stock-based compensation costs and estimates for the allocation of profit and losses to the noncontrolling interests. Actual results could differ materially from these estimates under different assumptions and conditions.
Reverse Stock Split
The Company decreased the total numberConcentration of outstanding shares with a 2-for-3 reverse stock split effective July 7, 2018 and subsequent to the date of these financial statements. All current and past period amounts stated herein and in the Quarterly Report on Form 10-Q attached hereto have given effect to the reverse stock split.
Revenue Recognition
The Company primarily earns revenue from the sale and installation of its Energy Servers both to direct and to lease customers, by providing services under its operations and maintenance services contracts and by selling electricity to customers under power purchase agreements. The Company offers its customers several ways to finance their purchase of a Bloom Energy Server. Customers may choose to purchase the Company’s Energy Servers outright. Customers may also lease the Company’s Energy Servers through one of the Company’s financing partners via the Company’s managed services program or as a traditional lease. Finally, customers may purchase electricity through the Company’s Power Purchase Agreement Programs.Risk
Direct Sales - To date, the Company has never sold an Energy Server without a maintenance service agreement, or vice-versa, nor does it have plans to do so in the near future. As a result, the Company recognizes revenue from contracts with customers for the sales of products and services included within these contracts in accordance with ASC 605-25, Revenue Recognition for Multiple-Element Arrangements.
Revenue from the sale and installation of Energy Servers to direct customers is recognized when all of the following criteria are met:
Persuasive Evidence of an Arrangement Exists. The Company relies upon non-cancelable sales agreements and purchase orders to determine the existence of an arrangement.
Delivery and Acceptance has Occurred. The Company uses shipping documents and confirmation from the Company’s installations team that the deployed systems are running at full power, as defined in each contract, to verify delivery and acceptance.
The Fee is Fixed or Determinable. The Company assesses whether the fee is fixed or determinable based on the payment terms associated with the transaction.
Collectability is Reasonably Assured. The Company assesses collectability based on the customer’s credit analysis and payment history.
Most of the Company’s arrangements are multiple-element arrangements with a combination of Energy Servers, installation and maintenance services. Products, including installation, and services generally qualify as separate units of accounting. For multiple-element arrangements, the Company allocates revenue to each unit of accounting based on an estimated selling price at the arrangement inception. The estimated selling price for each element is based upon the following hierarchy: vendor-specific objective evidence (VSOE) of selling price, if available; third-party evidence (TPE) of selling price, if VSOE of selling price is not available; or best estimate of selling price (BESP), if neither VSOE of selling price nor TPE of selling price are available. The total arrangement consideration is allocated to each separate unit of accounting using the relative estimated selling prices of each unit based on the aforementioned selling price hierarchy. The Company limits the amount of revenue recognized for delivered elements to an amount that is not contingent upon future delivery of additional products or services or upon meeting any specified performance conditions.
The Company has not been able to obtain reliable evidence of the selling price of the standalone Energy Server. Given that the Company has never sold an Energy Server without a maintenance service agreement, and vice-versa, the Company has no evidence of selling prices for either and virtually no customers have elected to cancel their maintenance agreements while continuing to operate the Energy Servers. The Company’s objective is to determine the price at which it would transact business if the items were being sold separately. As a result, the Company estimates its selling price driven primarily by its expected

margin on both the Energy Server and maintenance service agreement based on their respective costs or, in the case of maintenance service agreements, the estimated costs to be incurred during the service period.
Costs for Energy Servers include all direct and indirect manufacturing costs, applicable overhead costs and costs for normal production inefficiencies (i.e., variances). The Company then applies a margin to the Energy Servers to determine the selling price to be used in its BESP model. Costs for maintenance service arrangements are estimated over the life of the maintenance contracts and include estimated future service costs and future product costs. Product costs over the period of the service arrangement are impacted significantly by the longevity of the fuel cells themselves. After considering the total service costs, the Company applies a slightly lower margin to its service costs than to its Energy Servers because this best reflects the Company’s long-term service margin expectations.
As the Company’s business offerings and eligibility for the ITC evolve over time, the Company may be required to modify its estimated selling prices in subsequent periods and the Company’s revenue could be adversely affected.
The Company does not offer extended payment terms or rights of return for its products. Upon shipment of the product, the Company defers the product’s revenue until the acceptance criteria have been met. Such amounts are recorded within deferred revenue in the consolidated balance sheets. The related cost of such product is also deferred as a component of deferred cost in the consolidated balance sheets until customer acceptance. Prior to shipment of the product, any prepayment made by the customer is recorded as customer deposits. Customer deposits were $21.3 million and $10.2 million as of June 30, 2018 and December 31, 2017, respectively, and were included in deferred revenue and customer deposits in the consolidated balance sheets.
Traditional Leases - Under this financing option, the Company sells its Energy Servers through a direct sale to a financing partner who, in turn, leases the Energy Servers to the customer under a lease agreement between the customer and the financing partner. In addition, the Company contracts with the customer to provide extended maintenance services from the end of the standard one-year warranty period until the remaining duration of the lease term.
Payments received are recorded within deferred revenue in the consolidated balance sheets until the acceptance criteria as defined within the customer contract are met. The related cost of such product is also deferred as a component of deferred cost in the consolidated balance sheets, until acceptance.
The Company also sells extended maintenance services to its customers that effectively extend the standard warranty coverage. Payments from customers for the extended maintenance contracts are received at the beginning of each service year. Accordingly, the customer payment received is recorded as deferred revenue, and revenue is recognized ratably over the extended maintenance contract.
As discussed within the Direct Sales section above, the Company’s arrangements with its traditional lease customers are multiple-element arrangements as they include a combination of Energy Servers, installation and extended maintenance services. Accordingly, the Company recognizes revenue from contracts with customers for the sales of products and services included within these contracts in accordance with ASC 605-25, Revenue Recognition - Multiple-Element Arrangements.
Extended Maintenance ServicesGeographic Risk - The Company typically providesmajority of our revenue and long-lived assets are attributable to its direct sales customers a standard one-year warranty against manufacturing or performance defects. The Company also sells to these customers extended maintenance services that effectively extendoperations in the standard one-year warranty coverage at the customer’s option. These customers generally have an option to renew or cancel the extended maintenance services on an annual basis. Revenue is recognized from extended maintenance services ratably over the term of the service (or annual renewal period) using the estimates of value, as discussed above.
Sale-Leaseback (Managed Services) - The Company is a party to master lease agreements that provideUnited States for the sale ofall periods presented. Additionally, we sell our Energy Servers to third-partiesin Japan, China, India, and the simultaneous leasebackRepublic of the systems, which the Company then subleases to its customers.Korea, collectively our Asia Pacific region. In sale-leaseback sublease arrangements (also referred to as managed services), the Company first determines whether the Energy Servers under the sale-leaseback arrangement are “integral equipment.” An Energy Server is determined to be integral equipment when the cost to remove the system from its existing location, including the shipping costs of the Energy Server at the new site including any diminution in fair value, exceeds 10% of the fair value of the Energy Server at the time of its original installation. As the Energy Servers are determined not to be integral equipment, the Company determines if the leaseback is classified as a capital lease or an operating lease.
The Company’s managed services arrangements are classified as operating leases. As operating leases, the Company recognizes a portion of the net revenue, net of any commitments made to the customer to cover liabilities associated with insurance, property taxes and/or incentives recorded as managed service liabilities, and the associated cost of sale and then defers the portion of net revenue and cost of sale that represents the gross profit that is equal to the present value of the future minimum lease payments over the master leaseback term. For both capital and operating leasebacks, the Company records the

net deferred gross profit in its consolidated balance sheet as deferred income and amortizes the deferred income over the leaseback term as a reduction to the leaseback rental expense included in operating leases.
In connection with the Company’s common stock award agreement with a managed services customer, the share issuances are recorded as a reduction of product revenue when the installation milestones are achieved and are recorded as additional paid-in capital when the shares are issued.
Revenue Recognized from Power Purchase Agreement Programs (See Note 12)
In 2010, the Company began offering its Energy Servers through its Bloom Electrons financing program. This program is financed via special purpose Investment Company and Operating Company, referred to as a PPA Entity, and are owned partly by the Company and partly by third-party investors. The investors contribute cash to the PPA Entity in exchange for their equity interest, which then allows the PPA Entity to purchase the Energy Server from the Company. The cash contributions are classified as short-term or long-term restricted cash according to the terms of each power purchase agreement (PPA). As the Company identifies end customers, the PPA Entity enters into a PPA with the end customer pursuant to which the customer agrees to purchase the power generated by the Energy Server at a specified rate per kilowatt hour for a specified term, which can range from 10 to 21 years. The PPA Entity typically enters into a maintenance services agreement with the Company following the first year of service to extend the warranty service and performance guarantees. This intercompany arrangement is eliminated in consolidation. Those power purchase agreements that qualify as leases are classified as either sales-type leases or operating leases and those that do not qualify as leases are classified as tariff agreements. For both operating leases and tariff agreements, income is recognized as contractual amounts are due when the electricity is generated.
Sales-Type Leases - Certain arrangements entered into by certain Operating Companies, including Bloom Energy 2009 PPA Project Company, LLC (PPA I), 2012 ESA Project Company, LLC (PPA Company IIIa) and 2013B ESA Project Company, LLC (PPA Company IIIb), qualify as sales-type leases in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 840, Leases (ASC 840). The Company is responsible for the installation, operation and maintenance of the Energy Servers at the customers' sites, including running the Energy Servers during the term of the PPA which ranges from 10 to 15 years. Based on the terms of the customer contracts, the Company may also be obligated to supply fuel for the Energy Servers. The amount billed for the delivery of the electricity to PPA I’s customers primarily consists of returns on the amounts financed, including interest revenue, service revenue and fuel revenue for certain arrangements.
The Company is obligated to supply fuel to the Energy Servers that deliver electricity under the PPA I agreements. Based on the customer offtake agreements, the customers pay an all-inclusive rate per kWh of electricity produced by the Energy Servers. The consideration received under the PPA I agreements primarily consists of returns on the amounts financed including interest revenue, service revenue and fuel revenue.
As the Power Purchase Agreement Programs contain a lease, the consideration received is allocated between the lease elements (lease of property and related executory costs) and non-lease elements (other products and services, excluding any derivatives) based on relative fair value in accordance with ASC 605-25-13A (b). Lease elements include the leased system and the related executory costs (i.e. installation of the system, electricity generated by the system, maintenance costs). Non-lease elements include service, fuel, and interest related to the leased systems.
Service revenue and fuel revenue are recognized over the term of the PPA as electricity is generated. The interest component related to the leased system is recognized as interest revenue over the life of the lease term. The customer has the option to purchase the Energy Servers at the then fair market value at the end of the PPA contract term.
Service revenue related to sales-type leases of $0.9 million and $1.0 million for the three months ended June 30,March 31, 2019 and 2018, and 2017, respectively, and service revenue of $1.8 million and $2.1 million for the six months ended June 30, 2018 and 2017, respectively, is included in electricitytotal revenue in the consolidated statementsAsia Pacific region was 24.0% and 17.3%, respectively, of operations. Fuel revenueour total revenue.
Credit Risk - At March 31, 2019, customer A and customer B accounted for 58.0% and 12.1%, respectively, of $0.1 millionaccounts receivable. At December 31, 2018, customer A accounted for 66.8% of accounts receivable. At March 31, 2019 and $0.3 millionDecember 31, 2018, we did not maintain any allowances for doubtful accounts as we deemed all of our receivables fully collectible. To date, we have neither provided an allowance for uncollectible accounts nor experienced any credit loss.

Customer Risk - In the three months ended June 30, 2018March 31, 2019, revenue from customer A, customer B and 2017,customer C represented 24%, 25%,and 23%, respectively, of our total revenue. Customer A wholly owns a Third-Party PPA which purchases Energy Servers from us, however, such purchases and fuelresulting revenue are made on behalf of $0.3 million and $0.5 million for the six months ended June 30, 2018 and 2017, respectively, is included in electricity revenue in the consolidated statementsvarious customers of operations. Interest revenue of $0.4 million and $0.5 million forthis Third-Party PPA. In the three months ended June 30,March 31, 2018, and 2017, respectively, and interest revenue of $0.8 million and $1.0 million for the six months ended June 30, 2018 and 2017, respectively, is included in electricity revenue in the consolidated statements of operations.
Product revenue associated with the sale of the Energy Servers under the PPAs that qualify as sales-type leases is recognized at the present value of the minimum lease payments, which approximates fair value, assuming all other conditions for revenue recognition noted above have also been met. A sale is typically recognized as revenue when an Energy Server begins generating electricity and has been accepted, which is consistent across all purchase options in that acceptance generally occurs after the Energy Server has been installed and is running at full power as defined in each contract. There was no product revenue recognized under sales-type leases for the three and six months ended June 30, 2018 and 2017.

Operating Leases - Certain Power Purchase Agreement Program leases entered into by PPA Company IIIa, PPA Company IIIb, 2014 ESA Holdco, LLC (PPA Company IV) and 2015 ESA Holdco, LLC (PPA Company V) that are leases in substance but do not meet the criteria of sales-type leases or direct financing leases in accordance with ASC 840 are accounted for as operating leases. Revenue under these arrangements is recognized as electricity sales and service revenue and is provided to the customer at rates specified under the contracts. During the three months ended June 30, 2018 and 2017, revenue from electricity sales amounted to $7.7 millioncustomer B and $7.1 million, respectively. During the six months ended June 30, 2018customer D represented 53% and 2017, revenue from electricity sales amounted to $15.4 million and $14.2 million, respectively. During the three months ended June 30, 2018 and 2017, service revenue amounted to $3.8 million and $3.9 million, respectively. During the six months ended June 30, 2018 and 2017, service revenue amounted to $7.6 million and $7.8 million, respectively.
Tariff Agreement - PPA Company II entered into an agreement with Delmarva, PJM Interconnection, (PJM)17%, a regional transmission organization, and the Staterespectively, of Delaware under which PPA Company II provides the energy generated from its Energy Servers to PJM and receives a tariff as collected by Delmarva.
Revenue at the tariff rate is recognized as electricity sales and service revenue as it is generated over the term of the arrangement. Revenue relating to power generation at the Delmarva site of $5.7 million and $5.8 million for three months ended June 30, 2018 and 2017, respectively, and revenue relating to power generation at the Delmarva sites of $11.5 million and $11.6 million for the six months ended June 30, 2018 and 2017, respectively, is included in electricity sales in the consolidated statements of operations. Revenue relating to power generation at the Delmarva site of $3.4 million and $3.4 million for the three months ended June 30, 2018 and 2017, respectively, and revenue relating to power generation at the Delmarva sites of $6.9 million and $6.9 million for the six months ended June 30, 2018 and 2017, respectively, is included in service revenue in the consolidated statements of operations.
Incentives and Grants
Self-Generation Incentive Program (SGIP) - The Company’s PPA Entities’ customers receive payments under the SGIP, which is a program specific to the State of California that provides financial incentives for the installation of new and qualifying self-generation equipment that the Company owns. The SGIP funds are assigned to the PPA Entities by the customers and are recorded as other current assets and other long-term assets until received. For sales-type leases, the benefit of the SGIP funds are recorded as deferred revenue which is recognized as revenue when the Energy Server is accepted. For operating leases, the benefit of the SGIP funds are recorded as deferred revenue which is amortized on a straight-line basis over the PPA contract period. The SGIP program issues 50% of the fully anticipated amount in the first year the equipment is placed into service. The remaining incentive is then paid based on the size of the equipment (i.e., nameplate kilowatt capacity) over the subsequent five years. The SGIP program has operational criteria primarily related to fuel mixture and minimum output for the first five years after the qualified equipment is placed in service. If the operational criteria are not fulfilled, it could result in a partial refund of funds received. The SGIP program will expire on January 1, 2021.
The Company received $0.6 million and $1.0 million of SGIP funds for the three months ended June 30, 2018 and 2017, and $0.8 million and $1.7 million for the six months ended June 30, 2018 and 2017, respectively. There were no reductions or refunds of SGIP funds during the three and six months ended June 30, 2018 and 2017, and no accrual has been made for a refund of any incentives.
The Company makes SGIP reservations on behalf of certain of the PPA Entities. However, the PPA Entity receives the SGIP funds directly from the program and, therefore, bears the risk of loss if these funds are not paid.
U.S. Treasury Grants - The Company is eligible for U.S. Treasury grants on eligible property as defined under Section 1603 of the American Recovery and Reinvestment Act of 2009. However, to be eligible for the U.S. Treasury grants, a fuel cell system must have commenced construction in 2011 either physically or through the occurrence of sufficient project costs. For fuel cell systems under Power Purchase Agreement Programs, U.S. Treasury grants are considered a component of minimum lease payments. For fuel cell systems deployed under tariff legislation, the Company recorded the fuel cell systems net of the U.S. Treasury grants. U.S. Treasury grant receivables are classified as other current assets in the Company’s consolidated balance sheets. For operating leases, the benefit of the U.S. Treasury grant is recorded as deferred revenue and is amortized on a straight-line basis over the PPA contract period. No such grants have been accrued or received in the six months ended June 30, 2018 and 2017.
Investment Tax Credits (ITC) - Through December 31, 2016, the Company’s Energy Servers were eligible for federal investment tax credits, or ITCs, that accrued to eligible property under Internal Revenue Code Section 48. Under the Company's Power Purchase Agreement Programs, ITCs are primarily passed through to Equity Investors. Approximately 1% to 10% of the incentives are received by the Company, with the balance distributed to the remaining Equity Investors of the PPA Entity. These incentives are accounted for under the flow-through method. Subsequently, on February 9, 2018, the U.S. Congress passed legislation to extend the federal investment tax credits for fuel cell systems retroactive to January 1, 2017. Due

to the reinstatement of ITC in 2018, the benefit of ITC toour total revenue for product accepted was a $46.5 million benefit in the six months ended June 30, 2018 which included $44.9 million of product revenue benefit related to the retroactive ITC for 2017 acceptances.
The ITC program has operational criteria for the first five years after the qualified equipment is placed in service. If the qualified energy property is disposed of, or otherwise ceases to be investment credit property before the close of the five year recapture period is fulfilled, it could result in a partial reduction of the incentives. No ITC recapture has occurred during the three and six months ended June 30, 2018 and 2017.
Renewable Energy Credits (RECs) - RECs are tradeable energy credits that represent 1 megawatt hour of electricity generated from an eligible renewable energy resource generated in the U.S. RECs are primarily ‘held for use’ and are presented as part of other current assets and other long-term assets in the consolidated balance sheets until the RECs are sold and accounted for as revenue. The Company accounts for such RECs as output from the facility where they originate. The Company values these RECs at the lower of cost or market at the end of each reporting period.
To the extent the PPA Entities do not produce enough RECs to satisfy the requirements under certain of the Company’s PPA Entities’ PPAs, the Company may also acquire RECs under stand-alone purchase agreements with third parties to satisfy these REC obligations. Under PPAs with certain customers, the Company’s PPA Entities are required to deliver a specified quantity of biogas RECs or Western Electricity Coordinating Council (WECC) RECs. In order to meet these obligations, the Company’s PPA Entities may enter into REC purchase agreements with third parties to purchase a fixed quantity of the relevant RECs at a fixed price and on a fixed schedule. The PPA Entities utilize the Western Renewable Energy Information System (WREGIS), an independent tracking system for the region covered by the WECC, which allows the PPA Entities to manage RECs purchased and deliver the RECs to satisfy the customer obligation. Purchased RECs used to satisfy customer obligations are recorded at cost and are presented as part of other current assets and other long-term assets in the consolidated balance sheets. Costs of RECs purchased are expensed as the Company’s obligation to provide such RECs to customers occurs.
The Company estimates the number of excess RECs it will ultimately acquire under the non-cancelable purchase contracts over the number required to satisfy its obligations to its customers. The Company records a purchase commitment loss if the fair value of RECs is less than the fixed purchase price amount. The purchase commitment loss is recorded on the consolidated balance sheets as a component of other current liabilities and other long-term liabilities.
Components of Revenue and Cost of Revenue
Revenue - The Company primarily recognizes revenue from the sale and installation of Energy Servers, the sales of electricity and by providing services under extended operations and under maintenance services contracts (together, service agreements).
Product Revenue - All of the Company’s product revenue is generated from the sale of the Company's Energy Servers to direct purchase and lease customers. The Company generally begins to recognize product revenue from contracts with customers for the sales of its Energy Servers once the Company achieves acceptance; that is, generally when the system has been installed and is running at full power as defined in each contract.
All of the Company’s product arrangements contain multiple elements representing a combination of revenue from Energy Servers, from installation and from maintenance services. Upon acceptance, the Company allocates fair value to each of these elements and the Company limits the amount of revenue recognized for delivered elements up to an amount that is not contingent upon future delivery of additional products or services or upon meeting any specified performance conditions. The sale of the Company’s Energy Servers also includes a standard one-year warranty, the estimated cost of which is recorded as a component of cost of product revenue.
Installation Revenue - All of the Company’s installation revenue is generated from the sale and installation of the Company's Energy Servers to direct purchase and lease customers. The Company generally begins to recognize installation revenue from contracts with customers for the sales of its Energy Servers once the Company achieves acceptance; that is, generally when the system has been installed and running at full power.
Service Revenue - Service revenue is generated from operations and maintenance services agreements that extend the standard one-year warranty coverage beyond the initial first year for Energy Servers sold under direct purchase, traditional lease and managed services sales. Customers can renew these agreements on an annual basis. Revenue is recognized ratably over the term of the renewed one-year service period. The Company anticipates that almost all of its customers will continue to renew their maintenance services agreement each year.
Electricity Revenue - The Company’s PPA Entities purchase Energy Servers from the Company and sell electricity produced by these systems to customers through long-term power purchase agreements (PPAs). Customers are required to

purchase all of the electricity produced by the Energy Servers at agreed-upon rates over the course of the PPA's contractual term. The Company recognizes revenue from the PPAs as the electricity is provided over the term of the agreement.
Cost of Product Revenue - Cost of product revenue consists of costs of Energy Servers that the Company sells to direct and lease customers, and includes costs paid to the Company’s materials suppliers, personnel costs, certain allocated costs, shipping costs, provisions for excess and obsolete inventory and the depreciation costs of the Company’s equipment. Estimated standard one-year warranty costs are also included in cost of product revenue, see Warranty Costs below.
Cost of Installation Revenue - Cost of installation revenue consists of the costs to install the Energy Servers that the Company sells to direct and lease customers, and includes costs paid to the Company’s materials and service providers, personnel costs and allocated costs.
Cost of Service Revenue - Cost of service revenue consists of costs incurred under maintenance service contracts for all customers including direct sales, lease and Power Purchase Agreement Program customers, and includes personnel costs for the Company’s customer support organization, certain allocated costs and extended maintenance-related product repair and replacement costs.
Cost of Electricity Revenue - Cost of electricity revenue primarily consists of the depreciation of the cost of the Energy Servers owned by the PPA Entities and the cost of gas purchased in connection with the Company’s first PPA Entity. The cost of electricity revenue is generally recognized over the term of the customer’s PPA contract. The cost of depreciation of the Energy Servers is reduced by the amortization of any U.S. Treasury Department grant payment in lieu of the energy investment tax credit associated with these systems.
Warranty Costs - The Company generally warrants its products sold to its direct customers for one year following the date of acceptance of the products (“standard one-year warranty”). Additionally, as part of its MSAs, the Company provides output and efficiency guarantees (collectively “performance guarantees”) to its customers which contractually guarantee specified levels of efficiency and output. Such amounts have not been material to date.
As part of both its standard one-year warranty and MSA obligations, the Company monitors the operations of the underlying systems, including their efficiency and output levels. The performance guarantee payments represent maintenance decisions made by the Company and are accounted for as costs of goods sold. To estimate the warranty costs, the Company continuously monitors product returns for warranty failures, and maintains the reserve for the related warranty expense based on various factors including historical warranty claims, field monitoring and results of lab testing. The Company’s obligations under its standard product warranty and MSAs are generally in the form of product replacement, repair or reimbursement for higher customer electricity costs. Further, if the Energy Servers run at a lower efficiency or power output than the Company committed under its performance guarantee, the Company will reimburse the customer for this underperformance. The Company’s obligation includes ensuring the customer’s equipment operates at least at the efficiency and power output levels set forth in the customer agreement. The Company’s aggregate reimbursement obligation for this performance guarantee for each order is capped at a portion of the purchase price.
The standard one-year warranty covers defects in materials and workmanship under normal use and service conditions, and against manufacturing or performance defects. The Company’s warranty accrual represents its best estimate of the amount necessary to settle future and existing claims during the warranty period as of the balance sheet date. The Company accrues for warranty costs based on estimated costs that may be incurred including material costs, labor costs and higher customer electricity costs should the units not work for extended periods. Estimated costs associated with standard one-year warranty, including the performance guarantee payments, are recorded at the time of sale as a component of costs of goods sold.
Shipping and Handling Costs - The Company records costs related to shipping and handling in cost of revenue.
Sales and Utility Taxes - The Company recognizes revenue on a net basis for taxes charged to its customers and collected on behalf of the taxing authorities.
Components of Operating Expenses
Advertising and Promotion Costs - Expenses related to advertising and promotion of products are charged to sales and marketing expense as incurred. The Company did not incur any material advertising or promotion expenses during the three and six months ended June 30, 2018 and 2017.
Research and Development - The Company conducts internally funded research and development activities to improve anticipated product performance and reduce product life-cycle costs. Research and development costs are expensed as incurred and include salaries and expenses related to employees conducting research and development.

Stock-Based Compensation - The Company accounts for stock options and restricted stock units (RSUs) awarded to employees and non-employee directors under the provisions of Financial Accounting Standards Board Accounting Standards Codification Topic 718 - Compensation-Stock Compensation (ASC 718) using the Black-Scholes valuation model to estimate fair value. The Black-Scholes valuation model requires the Company to make estimates and assumptions regarding the underlying stock’s fair value, the expected life of the option and RSU, the risk-free rate of return interest rate, the expected volatility of the Company's common stock price and the expected dividend yield. In developing estimates used to calculate assumptions, the Company establishes the expected term for employee options and RSUs, as well as expected forfeiture rates, based on the historical settlement experience and after giving consideration to vesting schedules. Forfeitures are estimated at the time of grant and revised in subsequent periods, if necessary, if actual forfeitures differ from initial estimates. Stock-based compensation expense is recorded net of estimated forfeitures such that expense is recorded only for those stock-based awards that are expected to vest. Previously recognized expense is reversed for the portion of awards forfeited prior to vesting as and when the forfeitures occurred. The Company typically records stock-based compensation expense under the straight-line attribution method over the vesting term, which is generally five years, and records stock-based compensation expense for performance based awards using the graded-vesting method. Stock-based compensation expense is recorded in the consolidated statements of operations based on the employees’ respective function.
Stock-based compensation cost for RSUs is measured based on the fair value of the underlying shares on the date of grant. Up to June 30, 2018, RSUs were subject to a time-based vesting condition and a performance-based vesting condition, both of which require satisfaction before the RSUs were vested and settled for shares of common stock. The performance-based condition was tied to a liquidity event such as a sale event or the completion of the Company’s IPO. The time-based condition ranges between six months to two years from the end of the lock-up period after a liquidity event. Subsequent to June 30, 2018, RSUs are only subject to a time-based vesting condition. No expense related to these awards will be recognized unless the performance condition is satisfied.
Compensation expense for equity instruments granted to non-employees is measured on the date of performance at the fair value of the consideration received or the fair value of the equity instruments issued, whichever is more reliably measured. Compensation expense for equity instruments granted to non-employees is periodically remeasured as the underlying instruments vest. The fair value of the equity instruments is charged to earnings over the term of the service agreement.
The Company records deferred tax assets for awards that result in deductions on the Company’s income tax returns, unless the Company cannot realize the deduction (i.e., the Company is in a net operating loss (NOL) position), based on the amount of compensation cost recognized and the Company’s statutory tax rate. Beginning in the first quarter of fiscal 2017 with the adoption of ASU 2016-09 on a prospective basis, stock-based compensation excess tax benefits or deficiencies are reflected in the consolidated statements of operations as a component of the provision for income taxes. No tax benefit or expense for stock-based compensation has been recorded for the three and six months ended June 30, 2018 and 2017, since the Company remains in an NOL position.
Determining the amount of stock-based compensation to be recorded requires the Company to develop estimates for the inputs used in the Black-Scholes valuation model to calculate the grant-date fair value of stock options. The Company used the following weighted-average assumptions in applying the Black-Scholes valuation model:
  Three Months Ended
June 30,
 Six Months Ended
June 30,
  2018 2017 2018 2017
       
Risk-free interest rate 2.73%—2.77%
 2.01% - 2.07%
 2.49% - 2.77%
 2.01% - 2.07%
Expected term (in years) 6.21—6.69
 6.12—6.62
 6.18—6.69
 6.08—6.62
Expected dividend yield 
 
 
 
Expected volatility 54.6% 59.8% 54.6% -55.1%
 59.8% - 61.0%
The risk free interest rate for periods within the contractual life of the option is based on the U.S. Treasury zero coupon issues in effect at the grant date for periods corresponding with the expected term of option. The Company’s estimate of an expected term is calculated based on the Company’s historical share option exercise data. The Company has not and does not expect to pay dividends in the foreseeable future. The estimated stock price volatility is derived based on historical volatility of the Company’s peer group, which represents the Company’s best estimate of expected volatility.
The amount of stock-based compensation recognized during a period is based on the value of that portion of the awards that are ultimately expected to vest. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from estimates. The term “forfeitures” is distinct from “cancellations” or “expirations” and represents only the unvested portion of the surrendered option. The Company reviews historical forfeiture data and determines

the appropriate forfeiture rate based on that data. The Company reevaluates this analysis periodically and adjusts the forfeiture rate as necessary and ultimately recognizes the actual expense over the vesting period only for the shares that vest.
Refer to Note 11 - Stock-Based Compensation and Employee Benefits for further discussion of the Company’s stock-based compensation arrangements.
Income Taxes - The Company accounts for income taxes using the liability method under Financial Accounting Standards Board Accounting Standards Codification Topic 740 - Income Taxes (ASC 740). Under this method, deferred tax assets and liabilities are determined based on net operating loss carryforwards, research and development credit carryforwards and temporary differences resulting from the different treatment of items for tax and financial reporting purposes. Deferred items are measured using the enacted tax rates and laws that are expected to be in effect when the differences reverse. Additionally, the Company must assess the likelihood that deferred tax assets will be recovered as deductions from future taxable income. The Company has provided a full valuation allowance on its deferred tax assets because it believes it is more likely than not that its deferred tax assets will not be realized.
The Company follows the accounting guidance in ASC 740-10, which requires a more-likely-than-not threshold for financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. The Company records a liability for the difference between the benefit recognized and measured pursuant to ASC 740-10 and the tax position taken or expected to be taken on the Company’s tax return. To the extent that the assessment of such tax positions change, the change in estimate is recorded in the period in which the determination is made. The Company establishes reserves for tax-related uncertainties based on estimates of whether, and the extent to which, additional taxes will be due. These reserves are established when the Company believes that certain positions might be challenged despite the Company’s belief that the tax return positions are fully supportable. The reserves are adjusted in light of changing facts and circumstances such as the outcome of a tax audit. The provision for income taxes includes the impact of reserve provisions and changes to reserves that are considered appropriate. The Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense.
Comprehensive Loss - The Company’s comprehensive loss is comprised of the Company’s net loss and unrealized gains (losses) on the remeasurement of the effective portion of the Company’s interest rate swap agreements to fair value and on the Company’s available for sale securities.
Fair Value Measurement
Financial Accounting Standards Board ("FASB") Accounting Standards Codification Topic 820 - Fair Value Measurements and Disclosures ("ASC 820)820"), defines fair value, establishes a framework for measuring fair value under USU.S. GAAP and enhances disclosures about fair value measurements. Fair value is defined under ASC 820 as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value under ASC 820 must maximize the use of observable inputs and minimize the use of unobservable inputs. The guidance describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value which are the following:value:
Level 1 Quoted prices in active markets for identical assets or liabilities. Financial assets utilizing Level 1 inputs typically include money market securities and U.S. Treasury securities.
   
Level 2 Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Financial instruments utilizing Level 2 inputs include interest rate swaps.
   
Level 3 Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Financial liabilities utilizing Level 3 inputs include natural gas fixed price forward contract derivatives, warrants issued to purchase the Company’s preferred stock and embedded derivatives bifurcated from convertible notes.derivatives. Derivative liability valuations are performed based on a binomial lattice model and adjusted for illiquidity and/or nontransferability and such adjustments are generally based on available market evidence.
Components of Balance Sheet
Cash, Cash Equivalents, Short-Term Investments and Restricted Cash - The Company considers highly liquid short-term investments with original maturities of 90 days or less at the date of purchase as cash equivalents.

The Company considers highly liquid investments with original maturities of greater than 90 days at the date of purchase as short-term investments. Short-term investments are reported at fair value with unrealized gains or losses, net of tax, recorded in accumulated other comprehensive income (loss). The specific identification method is used to determine the cost of any securities disposed with any realized gains or losses recognized as income or expense in condensed consolidated statements of operations. Short-term investments are anticipated to be used for current operations and are, therefore, classified as available-for-sale in current assets even though their maturities may extend beyond one year. The Company periodically reviews short-term investments for impairment. In the event a decline in value is determined to be other-than-temporary, an impairment loss is recognized. When determining if a decline in value is other-than-temporary, the Company takes into consideration the current market conditions and the duration and severity of and the reason for the decline as well as considering the likelihood that it would need to sell the security prior to a recovery of par value.
As of June 30, 2018, short-term investments were comprised of $15.7 million of U.S. Treasury Bills. As of December 31, 2017, short-term investments were comprised of $26.8 million of U.S. Treasury Bills. The costs of these securities approximated their fair values and there were no material gross realized or unrealized gains, gross realized or unrealized losses or impairment for the periods ended June 30, 2018 and December 31, 2017. As of June 30, 2018, all investments were scheduled to mature within the next twelve months.
Restricted cash is held as collateral to provide financial assurance that the Company will fulfill commitments related to its power purchase agreement financings, its debt service reserves, its maintenance service reserves and its facility lease agreements. Restricted cash that is expected to be used within one year of the balance sheet date is classified as a current asset, whereas restricted cash expected to be used more than a year from the balance sheet date is classified as a non-current asset.
Derivative Financial Instruments - The Company enters into derivative forward contracts to manage its exposure relating to the fluctuating price of fuel under certain of its power purchase agreements entered in connection with the Bloom Electrons program (refer to Note 12 - Power Purchase Agreement Programs). In addition, the Company enters into fixed forward swap arrangements to convert variable interest rates on debt to a fixed rate. The Company also issued derivative financial instruments embedded in its 6% Notes as a means by which to provide additional incentive to investors and to obtain a lower cost cash-source of funds.
Derivative transactions are governed by procedures covering areas such as authorization, counterparty exposure and hedging practices. Positions are monitored based on changes in the spot price in the commodity market and their impact on the market value of derivatives. Credit risk on derivatives arises from the potential for counterparties to default on their contractual obligations to the Company. The Company limits its credit risk by dealing with counterparties that are considered to be of high credit quality. The Company does not enter into derivative transactions for trading or speculative purposes.
The Company accounts for its derivative instruments as either assets or liabilities and carries them at fair value on the consolidated balance sheets. Changes in the fair value of the derivatives that qualify and are designated as cash flow hedges are recorded in accumulated other comprehensive loss on the consolidated balance sheets and for those that do not qualify for hedge accounting or are not designated as hedges are recorded through earnings in the consolidated statements of operations.
While the Company hedges certain of its natural gas requirements under its power purchase agreements, it has not designated these forward contracts as hedges for accounting purposes. Therefore, the Company records the change in the fair value of its forward contracts in cost of revenue on the consolidated statements of operations. The fair value of the forward contracts is recorded on the consolidated balance sheets as a component of accrued other current liabilities and derivative liabilities. As the forward contracts are considered economic hedges, the changes in the fair value of the forward contracts are classified as operating activities within the statement of cash flows, which is consistent with the classification of the cash flows of the hedged item.
The Company’s interest rate swap arrangements qualify as cash flow hedges for accounting purposes as they effectively convert variable rate obligations into fixed rate obligations. The Company evaluates and calculates the effectiveness of the hedge at each reporting date. The effective change is recorded in accumulated other comprehensive loss and will be recognized as interest expense on settlement. Ineffectiveness is recorded in other income (expense), net. If a cash flow hedge is discontinued due to changes in the forecasted hedged transactions, hedge accounting is discontinued prospectively and unrealized gain or loss on the related derivative is recorded in accumulated other comprehensive loss and is reclassified into earnings in the same period during which the hedged forecasted transaction affects earnings. The fair value of the swap arrangement is recorded on the consolidated balance sheets as a component of accrued other current liabilities and derivative liabilities. The changes in fair value of swap agreement are classified as operating activities within the statement of cash flows, which is consistent with the classification of the cash flows of the hedged item.
The Company issued convertible notes with conversion features. These conversion features were evaluated under ASC topic 815-40, were determined to be embedded derivatives and were bifurcated from the debt and are classified as liabilities on

the consolidated balance sheets. The Company records these derivative liabilities at fair value and adjusts the carrying value to their estimated fair value at each reporting date with the increases or decreases in the fair value recorded as a gain (loss) on revaluation of warrant liabilities and embedded derivatives in the consolidated statements of operations.
Customer Financing Receivables - Leases are classified as either operating or sales-type leases in accordance with the relevant accounting guidelines. Customer financing receivables are generated by Energy Servers leased to PPA Entities’ customers in leasing arrangements that qualify as sales-type leases. Financing receivables represents the gross minimum lease payments to be received from customers and the system’s estimated residual value, net of unearned income and allowance for estimated losses. Initial direct costs for sales-type leases are recognized as cost of revenue when the Energy Servers are placed in service.
The Company reviews its customer financing receivables by aging category to identify significant customer balances with known disputes or collection issues. In determining the allowance, the Company makes judgments about the creditworthiness of a majority of its customers based on ongoing credit evaluations. The Company also considers its historical level of credit losses and current economic trends that might impact the level of future credit losses. The Company writes off customer financing receivables when they are deemed uncollectible. The Company has not had to maintain an allowance for doubtful accounts to reserve for potentially uncollectible customer financing receivables as historically all of its receivables on the consolidated balance sheets have been paid and are expected to be paid in full.
Accounts Receivable - Accounts receivable primarily represents trade receivables from sales to customers recorded at net realizable value. As the Company does for its customer financing receivables, the Company reviews its accounts receivable by aging category to identify significant customer balances with known disputes or collection issues. In determining the allowance, the Company makes judgments about the creditworthiness of a majority of its customers based on ongoing credit evaluations. The Company also considers its historical level of credit losses and current economic trends that might impact the level of future credit losses. The Company writes off accounts receivable when they are deemed uncollectible. The Company has not had to maintain an allowance for doubtful accounts to reserve for potentially uncollectible accounts receivable as historically all of its receivables on the consolidated balance sheets have been paid and are expected to be paid in full.
Inventories - Inventories consist principally of raw materials, work-in-process and finished goods and are stated on a first-in, first-out basis at the lower of cost or net realizable value.
The Company records inventory excess and obsolescence provisions for estimated obsolete or unsellable inventory, including inventory from purchase commitments, equal to the difference between the cost of inventory and estimated net realizable value based upon assumptions about market conditions and future demand for product generally expected to be utilized over the next 12 to 24 months, including product needed to fulfill the company’s warranty obligations. If actual future demand for the Company’s products is less than currently forecasted, additional inventory provisions may be required. Once a provision is recorded, it is maintained until the product to which it relates to is sold or otherwise disposed. The inventory reserves were $14.1 million and $15.7 million as of June 30, 2018 and December 31, 2017, respectively.
Property, Plant and Equipment - Property, plant and equipment, including leasehold improvements, are stated at cost, less accumulated depreciation. Energy Servers are depreciated to their residual values over the terms of the power purchase and tariff agreements. Leasehold improvements are depreciated over the shorter of the lease term or their estimated depreciable lives. Buildings are amortized over the shorter of the lease or property term or their estimated depreciable lives.
Depreciation is calculated using the straight-line method over the estimated depreciable lives of the respective assets as follows:
Depreciable Lives
Energy Servers15-21 years
Computers, software and hardware3-5 years
Machinery and equipment5-10 years
Furniture and fixtures3-5 years
Leasehold improvements1-5 years
Buildings35 years
When assets are retired or disposed, the assets and related accumulated depreciation and amortization are removed from the Company's general ledger and the resulting gain or loss is reflected in the consolidated statements of operations.
Foreign Currency Transactions - The functional currency of the Company’s foreign subsidiaries is the U.S. dollar since they are considered financially and operationally integrated. Foreign currency monetary assets and liabilities are remeasured

into U.S. dollars at end-of-period exchange rates. Nonmonetary assets and liabilities such as property, plant and equipment and equity are remeasured at historical exchange rates. Revenue and expenses are remeasured at average exchange rates in effect during each period, except for those expenses related to the previously noted balance sheet amounts which are remeasured at historical exchange rates. Transaction gains and losses are included as a component of other expense, net in the Company’s consolidated statements of operations and have not been significant for all periods presented.
Convertible Preferred Stock Warrants - The Company accounts for freestanding warrants to purchase shares of its convertible preferred stock as liabilities on the consolidated balance sheets at fair value upon issuance. The convertible preferred stock warrants are recorded as a liability because the underlying shares of convertible preferred stock are contingently redeemable which, therefore, may obligate the Company to transfer assets at some point in the future. The warrants are subject to remeasurement to fair value at each balance sheet date or immediately before exercise of the warrants. Any change in fair value is recognized in the consolidated statements of operations. The Company’s convertible preferred stock warrants will continue to be remeasured until the earlier of the exercise or expiration of warrants, the completion of a deemed liquidation event, the conversion of convertible preferred stock into common stock or until the convertible preferred stock can no longer trigger a deemed liquidation event. At that time, the convertible preferred stock warrant liability will be reclassified to convertible preferred stock or additional paid-in capital, as applicable. These warrants were valued on the date of issuance, using the Probability-Weighted Expected Return Model (PWERM). In accordance with ASC 480 - Distinguish Liability from Equity (ASC 480), these warrants are classified within warrant liability in the consolidated balance sheets.
Allocation of Profits and Losses of Consolidated Partnerships to Noncontrolling Interests - The Company generally allocates profits and losses to noncontrolling interests under the hypothetical liquidation at book value (HLBV) method. HLBV is a balance sheet-oriented approach for applying the equity method of accounting when there is a complex structure, such as the flip structure of the PPE Entities. The determination of equity in earnings under the HLBV method requires management to determine how proceeds upon a hypothetical liquidation of the entity at book value would be allocated between its investors. The noncontrolling interests balance is presented as a component of permanent equity in the consolidated balance sheets. Noncontrolling interests with redemption features, such as put options, that are not solely within the Company’s control are considered redeemable noncontrolling interests. Exercisability of put options are solely dependent upon the passage of time, and hence, such put options are considered to be probable of becoming exercisable. The Company elected to accrete changes in the redemption value over the period from the date it becomes probable that the instrument will become redeemable to the earliest redemption date of the instrument using an interest method. The balance of redeemable noncontrolling interests is reported at the greater of its carrying value or its maximum redemption value at each reporting date. The redeemable noncontrolling interests are in the temporary equity section in the mezzanine section of the consolidated balance sheets as redeemable noncontrolling interests. Refer to Note 12 - Power Purchase Agreement Programs for more information.
For income tax purposes, the Equity Investor committed to invest in the PPE Entities receives a greater proportion of the share of losses and other income tax benefits. This includes the allocation of investment tax credits which are distributed to the Equity Investor through an Investment Company subsidiary of the Company. Allocations are initially based on the terms specified in each respective partnership agreement until the Equity Investor’s targeted rate of return specified in the partnership agreement is met (the "flip" of the flip structure) whereupon the allocations change. In some cases, after the Equity Investors receive their contractual rate of return, the Company receives substantially all of the remaining value attributable to the long-term recurring customer payments and the other incentives.
Recent Accounting Pronouncements
Revenue Recognition - In May 2014,Accounting Guidance Implemented in Fiscal Year 2019
Other than the FASB issued guidance which will replace numerous requirements in US GAAP, including industry-specific requirements, and provide companies with a single revenue recognition model for recognizing revenue from contracts with customers. The core principle of the new standard is that a company should recognize revenue to show the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In August 2015, the FASB deferred the effective date by one year to December 15, 2018 for annual reporting periods beginning after that date. The FASB also permitted early adoption of accounting guidances mentioned below, there have been no other significant changes in our reported financial position or results of operations and cash flows resulting from the standard, but not beforeadoption of new accounting pronouncements. There have been no changes to our significant accounting policies that were disclosed in our Annual Report on Form 10-K for the original effective date offiscal year ended December 15, 2016. During 2016, the FASB issued several amendments to the standard, including clarification to the guidance on reporting revenues as31, 2018 that have had a principal versus an agent, identifying performance obligations, accounting for intellectual property licenses, assessing collectability, presentation of sales taxes, impairment testing for contract costs and disclosure of performance obligations.
The two permitted transition methods under the new standard are (1) the full retrospective method, in which case the standard would be applied to each prior reporting period presented, and the cumulative effect of applying the standard would be recognized at the earliest period shown, or (2) the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application. The Company is in the process of assessing the

LeasesHedging Activities - In February 2016,During the FASB issued first three months of fiscal 2019, we adopted Accounting Standards Update ("ASU") 2017-12 Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities ("ASU 2016-02, Leases (Topic 842), which will replace most existing lease accounting guidance in US GAAP. The core principle of the ASU is that an entity should2017-12") to help entities recognize the rights and obligations resulting from leases as assets and liabilities. ASU 2016-02 requires qualitative and specific quantitative disclosures to supplement the amounts recordedeconomic results of their hedging strategies in the financial statements so that usersstakeholders can better interpret and understand the effect of hedge accounting on reported results. It is intended to more about the nature ofclearly disclose an entity’s leasing activities, including significant judgmentsrisk exposures and changes in judgments. ASU 2016-02 will behow we manage those exposures through hedging, and it is expected to simplify the application of hedge accounting guidance. The new guidance is effective for the Companyannual periods beginning in fiscal 2020, and requires the modified retrospective method of adoption. The Company is evaluating the impact of this guidance on its consolidated financial statements and disclosures.
Financial Instruments - In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326). The pronouncement was issued to provide more decision-useful information about the expected credit losses on financial instruments and changes the loss impairment methodology. This pronouncement will be effective for the Company from fiscal year 2021. A prospective transition approach is required for debt securities for which an other-than-temporary impairment had been recognized before the effective date. The Company is currently evaluating the impact of the adoption of this update on its financial statements.
Statement of Cash Flows - In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments (Topic 230), which clarifies the classification of the activity in the consolidated statements of cash flows and how the predominant principle should be applied when cash receipts and cash payments have more than one class of cash flows. This pronouncement will be effective for the Company from fiscal year 2019,after December 15, 2018, with early adoption permitted. Adoption will be applied retrospectivelyWe adopted this standard on January 1, 2019. There was not a material impact to all periods presented. The Company is currently evaluating the impact this guidance will have on theour condensed consolidated financial statements and related disclosures.upon adoption.
Income Taxes - In October 2016,During the FASB issuedfirst three months of fiscal 2019, we adopted ASU 2016-16, Income Taxes—Intra-Entity Transfers of Assets Other Than Inventory (Topic 740), which requires that the entities recognize the income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs. The amendments in this ASU arestandard is effective for public business entitiesus in annual reporting periods beginning after December 15, 2017 andour Annual Report on Form 10-K for the interim periods therein,fiscal year ended December 31, 2019 and for all other entities in annual reporting periods beginning after December 15, 2018, and interim reporting periods in annual reporting periods beginning after December 15, 2019. Early adoption is permitted only atrequired to be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of an annual period for which no financial statements (interim or annual) have already been issued or made available for issuance. The Company is currently evaluating the impact of its pending adoption period. Adoption of this standard had no impact on itsour consolidated financials.financial statements.
StatementIncome Taxes - During the first three months of Cash Flowsfiscal 2019, we adopted ASU 2018-02 Income Statement—Reporting Comprehensive Income (Topic 220) Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income ("ASU 2018-02"), which permits reclassification of certain tax effects in Other Comprehensive Income ("OCI") caused by the U.S. tax reform enacted in December 2017 to retained earnings. We do not have any tax effect (due to full valuation allowance) in our OCI account, thus this guidance has no impact on us.
New Accounting Guidance to be Implemented
Revenue Recognition - In NovemberMay 2014, the FASB issued ASU 2014-14, Revenue From Contracts With Customers, as amended("ASU 2014-14"). The guidance provides principles for recognizing revenue for the transfer of promised goods or services to customers with the consideration to which the entity expects to be entitled in exchange for those goods or services, as well as guidance on the recognition of costs related to obtaining and fulfilling customer contracts. The guidance also requires expanded disclosures about the nature, amount, timing, and uncertainty of revenues and cash flows arising from customer contracts, including significant judgments and changes in judgments. ASU 2014-14 is effective for our annual period beginning January 1, 2019, and for our interim periods beginning on January 1, 2020. ASU 2014-14 can be adopted using either of two methods: (i) retrospective to each prior reporting period presented with the option to elect certain practical expedients as defined within the guidance (“full retrospective method”); or (ii) retrospective with the cumulative effect of initially applying the guidance recognized at the date of initial application and providing certain additional disclosures as defined per the guidance (“modified retrospective method”). We will adopt ASU 2014-14 for our fiscal year ended December 31, 2019 using the modified retrospective method, resulting in a cumulative-effect adjustment to retained earnings on January 1, 2019.
We are currently evaluating whether ASU 2014-14 will have a material impact on our consolidated financial statements and expect its adoption to have an impact related to the costs of obtaining our contracts, customer deposits, and deferred revenue. Further, in preparation for ASU 2014-14, we are in the process of updating our accounting policies, processes, internal controls over financial reporting, and system requirements.
Leases - In February 2016, the FASB issued ASU 2016-18, Statement of Cash Flows—Restricted Cash (Topic 230)2016-02, Leases(Topic 842), relatedas amended, which provides new authoritative guidance on lease accounting. Among its provisions, the standard requires lessees to recognize right-of-use assets and lease liabilities on the presentation of restricted cash inbalance sheet for operating leases and also requires additional qualitative and quantitative disclosures about lease arrangements. In March 2019 the statement of cash flows. The pronouncement requires that a statement of cash flows explain the change during the period in cash, cash equivalents, and amounts generally described as restricted cash. Amounts generally described as restricted cash are included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts. Refer to Note 3 - Financial Instruments for more information. The Company elected to early adopt the updatedFASB issued further guidance in ASU 2019-01, Leases (Topic 842), which provides clarifications to certain lessor transactions and other reporting matters. This guidance will be effective for us beginning January 2017 resulting in1, 2020, and requires the applicationmodified retrospective method of its requirementsadoption. Early adoption is permitted. We expect to all applicable periods presented. The adoption ofadopt this guidance did not have an effect on January 1, 2020 and expect to recognize right of use assets and lease liabilities for contracts currently recognized as operating leases where we are the Company’s results of operations, financial position or liquidity, other than the presentation of restricted cash or restricted cash equivalents in the statements of cash flows. The Company elected to early adopt the updated guidance in January 2017 resulting in the application of its requirements to all applicable periods presented.

Financial InstrumentsCloud Computing - In July 2017,August 2018, the FASB issued ASU 2017-11,2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40) Customer’s Accounting for Certain Financial Instruments with Down Round FeaturesImplementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract ("ASU 2018-15"), to clarify the guidance on the costs of implementing a cloud computing hosting arrangement that is a service contract. Under ASU 2018-15, the entity is required to follow the guidance in Subtopic 350-40, Internal-Use Software, to determine which implementation costs under the service contract to be capitalized as an asset and Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception.

Embedded Derivative on 6% Convertible Promissory Notes - OnBetween December 15, 2015 the Company issued $160.0 million of 6% Convertible Promissory Notes (6% Notes) that mature in December 2020. In addition, on January 29, 2016 and September 20, 2016, we issued $260.0 million convertible promissory notes due December 2020 ("6% Notes") to certain investors. The 6% Notes bore a 5% fixed interest rate, payable monthly either in cash or in kind, at our election. We amended the Company issued an additional $25.0 millionterms of the 6% Notes in June 2017 to reduce the collateral securing the notes and $75.0 million, respectively, ofto increase the interest rate from 5% to 6% Notes.. The 6% Notes are convertible at the option of the holders at a conversion price of $11.25 per share equal toshare. Upon the lower of $46.37 and 75% ofIPO, the offering price of the Company’s common stock sold in the IPO. The conversion feature is classified as an embedded derivative.
The valuationfinal value of the conversion feature was classified within Level 3 as it was valued using the binomial lattice method, which utilizes significant inputs that are unobservable in the market. Fair value was determined by estimated event dates from May 31, 2018 to June 30, 2019, estimated probabilities of likely events under the scenario which is based upon facts existing through the date of the Company's IPO, ITC tax credit renewed in February 2018, assumed event dates ranging from 5.0% to 35.0%, estimated maturity dates on December 1, 2020, estimated volatility of 40% to 50%, estimated common stock prices at estimated event dates ranging from $15 to $26, and risk free discount rates ranging from 1.68% to 2.35%.

Significant changes in any assumption input in isolation can result in a significant change in the fair value measurement. Generally, an increase in the market price of the Company’sour shares of common stock, an increase in natural gas prices, an increase in the volatility of the Company’sours shares of common stock and an increase in the remaining term of the conversion feature would each result in a directionally similar change in the estimated fair value of the Company’sour derivative liability. Such changesIncreases in such assumption values would increase the associated liability while decreases in these assumptionsassumption values would decrease the associated liability. An increase

in the risk-free interest rate or a decrease in the market price of the Company’sour shares of common stock would result in a decrease in the estimated fair value measurement and thus a decrease in the associated liability.

After the IPO, we paid the interest in cash when due and no additional interest accrued on the consolidated balance sheet on the 6% Notes.
On or after July 27, 2020, we may redeem, at our option, all or part of the 6% Notes if the last reported sale price of our common stock has been at least $22.50 for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending within the three trading days immediately preceding the date on which we provide written notice of redemption. In certain circumstances, the 6% Notes are also redeemable at our option in connection with a change of control.
Under the terms of the indenture governing the 6% Notes, we are required to comply with various restrictive covenants, including meeting reporting requirements, such as the preparation and delivery of audited consolidated financial statements, and restrictions on investments.

However, the minimum collateral test does restrict us with respect to investing in non-PPA subsidiaries. If we do not meet the minimum collateral test, we cannot invest cash into any non-PPA subsidiary that is not a guarantor of the notes. The 6% Notes also include a cross-acceleration provision which provides that the holders of at least 25% of the outstanding principal amount of the 6% Notes may cause such notes to become immediately due and payable if we or any of our subsidiaries default on any indebtedness in excess of $15.0 million such that the repayment of such indebtedness is accelerated.

In addition, we are required to maintain collateral which secures the 10% Notes based on debt ratio analyses. This minimum collateral test is not a negative covenant and does not result in a default if not met. However, the minimum collateral test does restrict us with respect to investing in non-PPA subsidiaries.

This fuel forward contract is used as part of our program to manage the risk for controlling the overall cost of natural gas. Our PPA Company I is the only PPA Company for which natural gas was provided by us. The fuel forward contract meets the definition of a derivative under U.S. GAAP. We have not elected to designate this contract as a hedge and, accordingly, any changes in its fair value is recorded within cost of revenue in the condensed consolidated statements of operations. The fair value of the contract is determined using a combination of factors including the counterparty’s credit rate and estimates of future natural gas prices.
For the three months ended March 31, 2019 and 2018, we marked-to-market the fair value of our fixed price natural gas forward contract and recorded a gain of $0.4 million and a loss of $0.9 million, respectively. For the three months ended March 31, 2019 and 2018, we recorded gains of $0.5 million and $1.1 million, respectively, on the settlement of these contracts. Gains and losses are recorded in cost of revenue - electricity in the condensed consolidated statements of operations.
6% Convertible Promissory Notes
On December 15, 2015, January 29, 2016, and September 10, 2016, the Companywe issued $160.0 million, $25.0 million, and $75.0 million, respectively, of 6% Convertible Promissory Notes ("6% Notes") that mature in December 2020. The 6% Notes are contractually convertible at the option of the holders at a conversion price per share equal to the lower of $46.37 and$20.61 or 75% of the offering price of the Company’sour common stock sold in an initial public offering. Upon the IPO, the options are convertible at the option of the holders at the conversion price of $11.25 per share.
The valuation of this embedded put feature iswas recorded as a derivative liability in the consolidated balance sheet. The notes were initially recorded net of a discount of $6.3 million and the fair value of the embedded derivatives within the notes was $115.8 million.sheet, measured each reporting period. Fair value was determined using the

binomial lattice method. The debt discount is being amortized through interest expense on the consolidated statements of operations over an accelerated three year amortization period based on when the Notes become puttable.
The Company measures the fair value of the derivatives at each reporting date and the CompanyWe recorded a loss of $23.5 million$0 and a loss of $0.5$7.5 million attributable to the change in valuation for the three months ended June 30,March 31, 2019 and 2018, and 2017, respectively. The Company recorded a gain of $2.4 million and a loss of $31.0 million attributable to the change in valuation for the six months ended June 30, 2018 and 2017, respectively. These gains and losses were included within loss on revaluation of warrant liabilities and embedded derivatives in gain (loss) on revaluation of warrant liabilities and embedded derivatives in the condensed consolidated statementstatements of operations. Upon the IPO, the final value of the conversion feature was $177.2 million and was reclassified from a derivative liability to additional paid-in capital.

During 2016, in connection with the 6% Convertible Promissory Notes entered in December 2015 and September 2016, the Company recorded a $9.2 million warrant expense for convertible redeemable common stock warrants issued to J.P. Morgan and CPPIB, to purchase the Company’s common stock up to a maximum of 146,666 shares and 166,222 shares, respectively.

Morgan assigned their warrants to CPPIB and all 312,888 warrant shares were issued to CPPIB, and the Company reclassified the $9.4 million of accrued warrant liabilities to additional paid in capital, which is not subject to further remeasurement in the fair value.

9. Income Taxes
For the three months ended June 30,March 31, 2019 and 2018, and 2017, the Company we recorded an expense for income taxes of $0.1 million on a pre-tax loss of $50.1 million for an effective tax rate of (0.3)% and an expenseprovision for income taxes of $0.2 million on a pre-tax loss of $67.4$88.1 million, for an effective tax rate of (0.3)%, respectively. For the six months ended June 30, 2018and 2017, the Company recorded an expensea provision for income taxes of $0.5 million on a pre-tax loss of $72.1 million for an effective tax rate of (0.6)% and an expense for income taxes of $0.4$0.3 million on a pre-tax loss of $132.5$22.0 million, for an effective tax rate of (0.3)%, respectively. The effective tax rateimpact for the three month periods presented is lower than the statutory federal tax rate primarily due to a full valuation allowance against U.S. deferred tax assets.
A valuation allowance is provided for the amount of deferred tax assets that, based on available evidence, is not more-likely-than-not to be realized. Management believes that, based on available evidence both positive and negative, it is more likely than not that the U.S. deferred tax assets will not be utilized and as such, a full valuation allowance has been recorded. The valuation allowance for deferred tax assets was $542.4 million as of December 31, 2017. There were no releases from the valuation allowance in either period.
At December 31, 2017, the Company had federal and state net operating loss carryforwards of $1.7 billion and $1.5 billion, respectively, which will expire, if unused, beginning in 2022 and 2018, respectively. In addition, at December 31, 2017 the Company had approximately $16.1 million of federal research credit, $6.6 million of federal investment tax credit, and $12.2 million of state research credit carryforwards. The federal tax credit carryforwards begin to expire in 2022. The state credit carryforwards may be carried forward indefinitely. The Company has not recorded deferred tax assets for the federal and state research credit carryforwards as the entire amount of the carryforwards represent unrecognized tax benefits.
U.S. law H.R.1, commonly referred as to the Tax Cuts and Jobs Act of 2017 (The Act) was enacted on December 22, 2017. Given the significance of the legislation, the SEC staff issued Staff Accounting Bulletin No. 118 (SAB 118), which allows registrants to record provisional amounts during a one year “measurement period”. However, the measurement period is deemed to have ended earlier when the registrant has obtained, prepared, and analyzed the information necessary to finalize its accounting. For the Global Intangible Low-Taxed Income (GILTI) provisions of the Tax Act, the Company has not yet completed its assessment or elected an accounting policy to either recognize deferred taxes for basis differences expected to reverse as GILTI or to record GILTI as period costs if and when incurred. During the measurement period, impacts of the law are expected to be recorded at the time a reasonable estimate for all or a portion of the effects can be made, and provisional amounts can be recognized and adjusted as information becomes available, prepared, or analyzed. The Company is in the measurement period, however the Company believes it has made reasonable estimate for all effects for periods presented.
As a result of The Act, the U.S. statutory tax rate was lowered from 34 percent to 21 percent effective on January 1, 2018. The Company is required to remeasure the U.S. deferred tax assets and liabilities to the new tax rate. The U.S. operation is in a net deferred tax asset position, offset by a full valuation allowance.

10. Net Loss per Share Attributable to Common Stockholders
Net loss per share (basic) attributable to common stockholders is calculated by dividing net loss attributable to common stockholders by the weighted-average shares of common stock outstanding for the period. Net loss per share (diluted) is computed by using the "if-converted" method when calculating the potential dilutive effect, if any, of convertible shares whereby net loss attributable to common stockholders is adjusted by the effect of dilutive securities such as awards under equity compensation plans and inducement awards under separate restricted stock unit ("RSU") award agreements. Net loss per share (diluted) attributable to common stockholders is then calculated by dividing the resulting adjusted net loss attributable to common stockholders by the combined weighted-average number of fully diluted common shares outstanding.
In July 2018, the Company completed an initial public offering of its common shares wherein 20,700,000 shares of Class A common stock were sold into the market. Added to existing shares of Class B common stock were shares mandatorily converted from various financial instruments as a result of the IPO.
There were no adjustments to net loss attributable to common stockholders in determining net loss attributable to common stockholders (diluted). Equally, there were no adjustments to the weighted average number of outstanding shares of common stock (basic) in arriving at the weighted average number of outstanding shares (diluted), as such adjustments would have been antidilutive.
Net loss per share is the same for each class of common stock as they are entitled to the same liquidation and dividend rights with the exception of voting rights. As a result, net loss per share (basic) and net loss per share (diluted) attributed to common stockholders are the same for both Class A and Class B common stock and are combined for presentation. The following table sets forth the computation of the Company’s basic and dilutedCompany's net loss per share (basic) and net loss per share (diluted) attributable to common stockholders (in thousands, except per share amounts):

12. Power Purchase Agreement Programs
Overview
In mid-2010, the Companywe began offering itsour Energy Servers through its Bloom Electrons program, which the Company denoteswe denote as Power Purchase Agreement Programs, financed via investment entities. Under these arrangements, an operating entity is created (the Operating Company)"Operating Company") which purchases the Energy Server from the Company.us. The end customer then enters into a power purchase agreement (PPA)("PPA") with the Operating Company to purchase the power generated by the Energy Server(s) at a specified rate per kilowatt hour for a specified term which can range from 10 to 21 years. In some cases similar to direct purchases and leases, the standard one-year warranty and performance guaranteesguaranties are included in the price of the product. The Operating Company also enters into a master services agreement (MSA)("MSA") with the Companyus following the first year of service to extend the warranty services and guaranteesguaranties over the term of the PPA. In other cases, the MSA including warranties and guarantees,guaranties are billed on a quarterly basis starting in the first quarter following the placed-in-service date of the energy server(s) and continuing over the term of the PPA. The first of such arrangements was considered a sales-type lease and the product revenue from that agreement was recognized up-frontup front in the same manner as direct purchase and lease transactions. Substantially all of the Company’sour subsequent PPAs have been accounted for as operating leases with the related revenue under those agreements recognized ratably over the PPA term as electricity revenue. The Company recognizesWe recognize the cost of revenue, primarily product costs and maintenance service costs, over the shorter of the estimated useful life of the Energy Server or the term of the PPA.
The CompanyWe and our third-party equity investors (Equity Investors)(together "Equity Investors") contribute funds into a limited liability investment entity (Investment Company)("Investment Company") that owns and is parent to the Operating Company (together, the PPA Entities)"PPA Entities"). The PPA Entities constitute variable investment entities (VIEs)("VIEs") under USU.S. GAAP. The Company hasWe have considered the provisions within the contractual agreements which grant itus power to manage and make decisions affecting the operations of these VIEs. The Company considersWe consider that the rights granted to the Equity Investors under the contractual agreements are more protective in nature rather than participating. Therefore, the Company haswe have determined under the power and benefits criterion of ASC 810 - Consolidations that it iswe are the primary beneficiary of these VIEs.

As the primary beneficiary of these VIEs, the Company consolidateswe consolidate in its financial statements the financial position, results of operations and cash flows of the PPA Entities, and all intercompany balances and transactions between the Companyus and the PPA Entities are eliminated in the consolidated financial statements.
The Company established six different PPA Entities to date. The contributed funds are restricted for use by the Operating Company to the purchase Energy Servers manufactured by the Company in its normal course of operations. All six PPA Entities utilized their entire available financing capacity and completed the purchase of Energy Servers as of June 30, 2018. Any debt incurred by the Operating Companies is non-recourse to the Company. Under these structures, each Investment Company is treated as a partnership for U.S. federal income tax purposes. Equity Investors receive investment tax credits and accelerated tax depreciation benefits.
The Operating Company acquires Energy Servers from the Companyus for cash payments that are made on a similar schedule as if the Operating Company were a customer purchasing an Energy Server from the Companyus outright. In the consolidated financial statements, the salesales of our Energy Servers by the Company to the Operating Company are treated as intercompany transactions after the elimination of intercompany balances. The acquisition of Energy Servers by the Operating Company is accounted for as a non-cash reclassification from inventory to Energy Servers within property, plant and equipment, net on the Company’sour condensed consolidated balance sheets. In arrangements qualifying for sales-type leases, the Company reduceswe reduce these recorded assets by amounts received from U.S. Treasury Department cash grants and from similar state incentive rebates.
The Operating Company sells the electricity to end customers under PPAs. Cash generated by the electricity sales, as well as receipts from any applicable government incentive program, is used to pay operating expenses (including the management and services the Company provideswe provide to maintain the Energy Servers over the term of the PPA) and to service the non-recourse debt with the remaining cash flows distributed to the Equity Investors. In transactions accounted for as sales-type leases, the Company recognizeswe recognize subsequent customer billings as electricity revenue over the term of the PPA and amortizes any applicable government incentive program grants as a reduction to depreciation expense of the Energy Server over the term of the PPA. In transactions accounted for as operating leases, the Company recognizeswe recognize subsequent customer payments and any applicable government incentive program grants as electricity revenue over the term of the PPA.
Upon sale or liquidation of a PPA Entity, distributions would occur in the order of priority specified in the contractual agreements.

We established six different PPA Entities to date. The contributed funds are restricted for use by the Operating Company to the purchase of Energy Servers manufactured by us in our normal course of operations, all six PPA Entities utilized their entire available financing capacity and have completed the purchase of their Energy Servers. Any debt incurred by the Operating Companies is non-recourse to us. Under these structures, each Investment Company is treated as a partnership for U.S. federal income tax purposes. Equity Investors receive investment tax credits and accelerated tax depreciation benefits. In 2016, we purchased the tax equity investor’s interest in PPA Company I ("PPA I"), which resulted in a change in our ownership interest in PPA I while we continued to hold the controlling financial interest in this company.

Some of the Company'sour PPA Entities contain structured provisions whereby the allocation of income and equity to the Equity Investors changes at some point in time after the formation of the PPA Entity. The change in allocations to Equity Investors (or the "flip") occurs based either on a specified future date or once the Equity Investors reaches its targeted rate of return. For PPA Entities with a specified future date for the flip, the flip occurs January 1 of the calendar year immediately following the year that includes the fifth anniversary of the date the last site achieves commercial operation.
The noncontrolling interests in PPA Company II, PPA Company IIIa and PPA Company IIIb are redeemable as a result of the put option held by the Equity Investors. The redemption value is the put amount. At June 30, 2018,March 31, 2019, and December 31, 2017,2018, the carrying value of redeemable noncontrolling interests of $54.9$58.8 million and $58.2$57.3 million, respectively, exceeded the maximum redemption value.

The Company’sOur exposure under these agreements is unknown because it involves future claims that may be made against the Company in the future,us but have not yet been made. To date, the Company haswe have not paid any claims or been required to defend any action related to its indemnification obligations. However, the Companywe may record charges in the future as a result of these indemnification obligations.
Warranty Costs - The CompanyWe generally warrants itswarrant our products sold to itsour direct customers for one year following the date of acceptance of the products (theunder a standard one-year warranty).warranty. As part of its MSAs, the Company provideswe provide output and efficiency guaranteesguaranties (collectively “performance guarantees”guaranties”) to itsour customers when systems operate below contractually specified levels of efficiency and output. Such amounts have not been material to date.
The standard one-year warranty covers defects in materials and workmanship under normal use and service conditions, and against manufacturing or performance defects. The Company’sWe accrue this warranty accrual represents itsexpense using our best estimate of the amount necessary to settle future and existing claims during the warranty period,claims as of the balance sheet date.
The Company’sOur obligations under its standard one-year warranty and MSA agreements are generally in the form of product replacement, repair or reimbursement for higher customer electricity costs. Further, if the Energy Servers run at a lower efficiency or power output than the Companywe committed under itsour performance guarantee, the Companyguaranty, we will reimburse the customer for the underperformance. The Company’sOur aggregate reimbursement obligation for this performance guaranteeguaranty for each order is capped at a portion of the purchase price. Prior to fiscal year 2014, certain MSAs with direct customers were accounted for as separately-priced warranty contracts under ASC 605-20-25 Separately Priced Extended Warranty and Product Maintenance Contracts (formerly FTB 90-1), in which we recorded an accrual for any expected costs that exceed the contracted revenues for that one-year service renewal arrangement, and is included as a component of the accrued warranty liability. Customers may renew the MSAs leading to future expense that is not recognized under GAAP until the renewal occurs. Over time, as our service offering evolved and we began managing the Energy Servers taking into consideration individual customer arrangements as well as our Bloom Energy Server fleet management objectives, our service offering evolved to the point that our services changed, becoming a more strategic offering for both us and our customers. Additionally, virtually all of our sales arrangements included bundled sales of maintenance service agreements along with the Energy Servers. The result is that we allocate a certain portion of the contractual revenue related to the Energy Servers to the MSAs based on our BESP compared to the stated amount in the service contracts.
Delaware Economic Development Authority - In March 2012, the Companywe entered into an agreement with the Delaware Economic Development Authority to provide a grant of $16.5 million as an incentive to establish a new manufacturing facility in Delaware and to provide employment for full time workers at the facility over a certain period of time. The grant contains two types of milestones that the Companywe must complete to retain the entire amount of the grant proceeds. The first milestone was to provide employment for 900 full time workers in Delaware by the end of the first recapture period of September 30, 2017. The second milestone was to pay these full time workers a cumulative total of $108.0 million in compensation by September 30, 2017. Further, thereThere are two additional recapture periods at which time the Companywe must continue to employ 900 full time workers and the cumulative total compensation paid by the Companyus is required to be at least $324.0 million by September 30, 2023. As of June 30, 2018, the CompanyMarch 31, 2019, we had 328334 full time workers in Delaware and paid $80.4$99.3 million in cumulative compensation. The Company hasAs of December 31, 2018, we had 338 full time workers in Delaware and paid $92.0 million in cumulative compensation. We have so far received $12.0 million of the grant which is contingent upon meeting the milestones through September 30, 2023. In the event that the Company doeswe do not meet the milestones, itwe may have to repay the Delaware Economic Development Authority, including up to $5.0 million on

September 30, 2021 and up to an additional $2.5 million on September 30, 2023. As of June 30, 2018, the CompanyMarch 31, 2019 we had cumulatively paid $1.5 million for recapture provisions and have recorded $10.5 million in other long-term liabilities for any potential repayments.recapture.
Self-Generation Incentive Program (SGIP)("SGIP") - The Company’sOur PPA Entities’ customers receive payments under the SGIP which is a program specific to the State of California that provides financial incentives for the installation of qualifying new qualifying self-generation equipment that the Company owns.we own. The SGIP program issues 50% of the fully anticipated amount in the first year the equipment is placed into service. The remaining incentive is then paid based on the size of the equipment (i.e., nameplate kilowatt capacity) over the subsequent five years.

The SGIP program has operational criteria primarily related to fuel mixture and minimum output for the first five years after the qualified equipment is placed in service. If the operational criteria are not fulfilled, it could result in a partial refund of funds received. However, for certain PPA Entities, the Company makeswe make SGIP reservations on behalf of the PPA Entity and, therefore, the PPA Entity bears the risk of loss if these funds are not paid.
Investment Tax Credits (ITC)("ITCs") - Through December 31, 2016, purchase of the Company’sOur Energy Servers wereare eligible for federal investment tax credits, or ITCs that accrued to eligiblequalified property under Internal Revenue Code Section 48. The48 when placed into service. However, the ITC program has operational criteria that extend for the first five years after the qualified equipment is placed in service.years. If the qualified energy property is disposed or otherwise ceases to be qualified investment credit property before the close of the five year recapture period is fulfilled, it could result in a partial reduction of the incentives. The Company's purchase of Energy Servers were made by the PPA Entities and, therefore, the PPA Entities bear the risk of repayment if the assets placed in service do not meet the ITC operational criteria in the future.
Legal Matters - From time to time, the Company iswe are involved in disputes, claims, litigation, investigations, proceedings and/or other legal actions consisting of commercial, securities and employment matters that arise in the ordinary course of business. The Company reviewsWe review all legal matters at least quarterly and assesses whether an accrual for loss contingencies needs to be recorded. The assessment reflects the impact of negotiations, settlements, rulings, advice of legal counsel and other information and events pertaining to a particular situation. The Company recordsWe record an accrual for loss contingencies when management believes that it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Legal matters are subject to uncertainties and are inherently unpredictable, so the actual liability in any such matters may be materially different from the Company’sour estimates. If an unfavorable resolution were to occur, there exists the possibility of a material adverse impact on the Company’s consolidated financial condition, results of operations or cash flows for the period in which the resolution occurs or on future periods.
In July 2018, two former executives of Advanced Equities, Inc., Keith Daubenspeck and Dwight Badger, filed a Statement of Claim with the American Arbitration Association in Santa Clara, CA, against us, Kleiner Perkins, Caufield & Byers, LLC (“KPCB”), New Enterprise Associates, LLC (“NEA”) and affiliated entities of both KPCB and NEA seeking to compel arbitration and alleging a breach of a confidential agreement executed between the parties on June 27, 2014 (“Confidential Agreement”). This Statement of Claim sought, among other things, to void the indemnification and confidentiality provisions under the Confidential Agreement and to recover attorneys’ fees and costs. The Statement of Claim was dismissed without prejudice on July 22, 2018. On September 19, 2018, an Amended Statement of Claim was filed by Messrs. Daubenspeck and Badger with the American Arbitration Association in Santa Clara, CA, against the parties. The Amended Statement of Claim alleges a breach of the Confidentiality Agreement and fraud in the inducement, securities fraud, racketeering and other claims. On May 7, 2019, KPCB and NEA were dismissed with prejudice. No date has yet been set for our response. We believe the Amended Statement of Claim to be without merit and as a result, we have recorded no loss contingency related to this claim.

In March of 2019, the Lincolnshire Police Pension fund filed a class action complaint in the Superior Court of the State of California, County of Santa Clara against us, certain members of our senior management, certain of our directors and the underwriters in our initial public offering alleging violations under Sections 11 and 15 of the Securities Act of 1933, as amended, for misleading statements or omissions in our Form S-1 Registration Statement in connection with our July 25, 2018 initial public offering. Two related class action cases were subsequently filed in the Santa Clara County Superior Court against the same defendants containing the same allegations; Rodriquez vs Bloom Energy et al was filed on April 22, 2019 and Evan vs Bloom Energy et al. was filed on May 7, 2019. As related cases, we expect they will be consolidated and a case management schedule set. Discovery is currently stayed.


14. Segment Information and Concentration of Risk
Segments and the Chief Operating Decision Maker (CODM)
The Company’s chief operating decision makers (CODMs)("CODMs"), the Chief Executive Officer and the Chief Financial Officer, review financial information presented on a consolidated basis for purposes of allocating resources and evaluating financial performance. The CODMs allocate resources and make operational decisions based on direct involvement with the Company’s operations and product development efforts. The Company is managed under a functionally-based organizational structure with the head of each function reporting to the Chief Executive Officer. The CODMs assess performance, including incentive compensation, based upon consolidated operations performance and financial results on a consolidated basis. As such, the Company has a single reporting segment and operating unit structure.
Concentration of Geographic Risk
Substantially all of the Company’s revenue and long-lived assets are attributable to operations in the United States for all periods presented.
Concentrations of Credit Risk
Financial instruments that potentially subject the Company to a concentration of credit risk consist primarily of cash and cash equivalents, short-term investments, accounts receivables, customer financing lease receivables and counterparties to derivative instruments.
The Company only invests cash and cash equivalents in institutions which maintain the highest ratings of creditworthiness. Short-term investments consist of U.S. Treasury Bills. The Company conducts periodic evaluations of the creditworthiness of its customers and the collectability of its accounts receivable and financing leases receivable and provides for potential credit losses as necessary in the consolidated financial statements. The Company limits its credit risk on derivative instruments by dealing only with counterparties that are considered to be of high credit quality.
To date, the Company has neither provided an allowance for uncollectible accounts nor experienced any credit loss.
Concentrations of Customer Risk
The Company's Energy Servers are sold at a significant purchase price with few numerical sales in any given quarter. Consequently in any particular period, a substantial proportion of total revenue is concentrated in a relatively small number of customers. In subsequent periods, the same is true for a different set of customers. Therefore, although revenue is highly concentrated in a few customers in a single quarterly period, such is not the case when examining revenue over longer terms.
In the three months ended June 30, 2018, total revenue from Macerich and The Southern Company represented 19% and 16% of the Company’s total revenue, respectively. In the six months ended June 30, 2018, total revenue from The Southern Company and Korea Energy represented 53% and 17% of the Company's total revenue, respectively. In the three months ended June 30, 2017, total revenue from Macerich and The Southern Company, represented 19% and 16% of the Company’s total

revenue, respectively. In the six months ended June 30, 2017, total revenue from The Southern Company and Korea Energy represented 53% and 17% of total revenue, respectively.
Concentrations of Supply Risk
The Company’s products are manufactured using a rare earth mineral. The suppliers for this raw material are primarily located in Asia. A significant disruption in the operations of one or more of these suppliers could impact the production of the Company’s products which could have a material adverse effect on its business, financial condition and results of operations.
Cybersecurity Risk
All of the Company's installed Energy Servers are connected to and controlled and monitored by the Company's centralized remote monitoring service. Additionally, the Company relies on internal computer networks for many of the systems used to operate the business generally. The Company may be vulnerable to breaches, unauthorized access, misuse, computer viruses or other malicious code and cyber-attacks. The Company takes protective measures and endeavors to modify these internal systems as circumstances warrant to prevent unauthorized intrusions or disruptions.

Overview
We provide an advanced distributed electric power generation solution, based on our proprietary solid oxide fuel cell technology that provides our customers with a reliable, resilient, sustainable and more cost effective clean alternative to the electric grid. Our solution, the Bloomour Energy Server, is an on-sitea stationary power generation platform built for the digital age and capable of delivering highly reliable, uninterrupted, 24x7 base loadconstant power that is fault tolerant, resilientalso clean and clean. We currently primarily target commercialsustainable. The Energy Server converts standard low-pressure natural gas or biogas into electricity through an electrochemical process without combustion, resulting in very high conversion efficiencies and industrial customers.lower harmful emissions than conventional fossil fuel generation. A typical configuration produces 250 kilowatts of power in a footprint roughly equivalent to that of half of a standard thirty-foot shipping container, or approximately 125 times more space-efficient than solar power generation. 250 kilowatts of power is roughly equivalent to the constant power requirement of a typical big box retail store. Any number of these Energy Server systems can be clustered together in various configurations to form solutions from hundreds of kilowatts to many tens of megawatts. 
We market and sell our Energy Servers primarily through our direct sales organization in the United States.States, and also have direct and indirect sales channels internationally. Recognizing that deploying our solutions requires a material financial commitment, from our customers, we typically seekhave developed a number of financing options to engagesupport sales of Energy Servers to customers that havelack the financial capability to either purchase our Energy Servers directly, who prefer to finance the acquisition using third party financing or arrange creditworthy counterpartieswho prefer to financing agreements. contract for our services on a pay-as-you-go model.
Our typical target commercial or industrial customer has historically been either an investment-grade entity or a customer with investment-grade attributes such as size, assets and revenue, liquidity, geographically diverse operations and general financial stability. We have recently expanded our below investment-grade customer base and have also expanded internationally to target customers with deployments on a wholesale grid. Given that our customers are typically large institutions with multi-level decision making processes, we generally experience a lengthy sales process.

The entity owning the Energy Server then enters into agreements with the customer pursuant to which the customer purchases the electricity generated by the Energy Server for a fixed price per kilowatt-hour (kWh). Our Power Purchase Agreement Programs include both the Bloom Electrons program, which includes an equity investment by us and South Korea. Our customer base includes 25 of the Fortune 100 companies. We believe thatin which we are currently capturing only a small percentage of our largest customers’ total energy spend, which gives us an opportunity for growth within those customers, particularlyrecognize revenue as the price of grid power increaseselectricity is produced, and our Third-Party PPA programs, in the areas where our existing customerswhich we have additional sites. Since the timing of revenueno equity investment and we recognize depends,revenue on acceptance.
For further information about our Power Purchase Agreement Programs, see Note 12 - Power Purchase Agreement Programs, to our consolidated financial statements included in part,this Quarterly Report on the option chosenForm 10-Q.

With our Bloom Electrons program, we endeavored to assist our customers' purchases by the customer to financedirectly participating in financing the purchase of their Energy Server. More recently, we have moved to providing the Energy Server,same service to our customers that may have accounted for a significant amount of product revenue in one period may not necessarily account for similar amounts of product revenue in future periods.
To date, substantially all ofwithout our revenue has been derived from customers baseddirect involvement in the United States. However,capital financing and therefore, having no equity investment in the resulting PPA. We refer to this purchase option as Third-Party PPA arrangements, structured in a near-identical manner and with the same terms and conditions as our Bloom Electrons program (described above), only without our assuming an equity position in the PPA structure. This way, we are increasing our sales efforts outside ofretain the United States, with initial customer installations in India, Japan and South Korea.
Althoughbenefits for the size of each system deployment can vary substantially and usually exceeds 250 kilowatts, we measure and track our system deployments and customer acceptances in 100 kilowatt equivalents. As of June 30, 2018, we had installed 3,281 of such systems, which is equivalent to 328 total megawatts.
The purchasemarketability of our Energy Servers without the capital burden and related installation costs have historically qualified forwithout the Federal Investment Tax Credit (ITC). Through 2016,potential financial liability.
Lease Programs
In our customersLease Programs, we sell the Energy Server to a financing party that in turn leases the Energy Server to the customer. We then enter into an operations and maintenance agreement with the customer. The customer pays the financing partners could take advantage of ITC. They could receiveparty a tax credit of 30% or $3,000 per kilowatt of their equipment purchase pricerent payment and the installation cost on their federal tax returns. This federal tax benefit expiredpays us an operations and maintenance fee. In our Lease programs we recognize revenue at the endtime of 2016. Accordingly,the sale to the financing party, which typically occurs in 2017, customers no longer receivedconnection with acceptance.
Managed Services Programs
In our Managed Services Programs, we sell the ITC benefit on purchases of our Energy Servers. In orderServer to offseta financing party and simultaneously lease the negative economic impact of that lost benefitEnergy Server back from the financing party. We then enter into an Energy Server services agreement with the customer. The customer pays us a fixed payment equal to our customerslease payment obligation to the financing party. In some cases, the customer may also pay us an operations and financing partners, in 2017maintenance fee. In our Managed Services programs we lowered our selling price to customers. Because many customers or financing partners would monetizerecognize revenue at the tax credit upfront, the actual impact to our selling price was generally greater than 30%. Subsequently, the ITC was reinstated by the U.S. Congress on February 9, 2018 and made retroactive to January 1, 2017. The resulting benefittime of the ITC renewal was recognized on our financial statements in the three months ending March 31, 2018.
We manufacture our Energy Servers at our facilities in California and Delaware. Duesale to the intensive manufacturing process necessary to build our systems, a significant portion of our manufacturing costs is fixed. We obtain our materials and components through a variety of third parties. Components and materials, direct labor and overhead such as facility and equipment expenses comprise the substantial majority of the costs of our Energy Servers. As we have commercialized and introduced successive generations of our Energy Servers, we have focused on reducing production costs. Our product costs per system manufactured have generally declined since delivering our first commercial product. These cost declines are the result of continuous improvements and increased automationfinancing party, which typically occurs in our manufacturing processes as well as our ability to reduce the costs of our materials and components, allowing us to gain greater economies of scaleconnection with our growth.acceptance.
We believe we have made significant improvements in our efficiency and the quality of our products. Our success depends in part on our ability to increase our products’ useful lives, which would significantly reduce our cost of services to maintain the Energy Servers over time.
Power Purchase OptionsAgreement Programs
Our customers may choosehave the option to purchase electricity produced by our Energy Servers outright or may choose to lease them through one of our financing partners as a traditional lease or a sale-leaseback sublease arrangement, the latter offinanced offering which we refer to as managed services. Our customers may alsoa Power Purchase Agreement Program, whereby one or more parties are equity investors in financing the entities that purchase electricity through Bloom Electrons, our power purchase financing program.

Depending on the financing arrangement, either our customers or the financing provider may utilize investment tax credits and other government incentives. The timing of the product-related cash flows to the Company is generally consistent across all the above financing options, whether direct purchase arrangements, leases or managed services.
We provide warranties and performance guarantees regarding the Energy Servers’ efficiency and output under all of our financing arrangements. Under direct purchase and traditional lease options, the warranty and guarantee is included in the price ofServers. The entity owning the Energy Server forthen enters into agreements with the first year. The warranty and guarantee may be renewed annually atcustomer pursuant to which the customer’s option as an operations and maintenance services agreement at predetermined prices for a period of up to 20 years. Historically, our customers have almost always exercised their option to renew under these operations and maintenance services agreements. Undercustomer purchases the managed services program, the operations and maintenance performance guarantees are included in the price ofelectricity generated by the Energy Server for a fixed period of 10 years, which may be extended atprice per kilowatt-hour (kWh). Our Power Purchase Agreement Programs include both the option of the parties for up to an additional 10 years with all payments made annually.
Our capacity to offer our Energy Servers through any of the financing arrangements above depends in large part on the ability of the parties involved in providing payment for the Energy Servers to monetize either the related investment tax credits, accelerated tax depreciation and other incentives, and/or the future power purchase obligations of the end customer. Interest rate fluctuations would also impact the attractiveness of any lease financing offerings for our customers. Additionally, the managed services option is limited by the creditworthiness of the customer and, as with all leases, the customer’s willingness to commit to making fixed payments regardless of the output of the system.

In 2017, we observed a shift in our customers’ purchase option preferences to our direct purchase options.
Purchase and Lease Programs
Initially, we only offered our Energy Servers on a purchase basis, in which we recognize revenue as the customer purchases the product directly from us. Included withinelectricity is produced, and our direct purchase option are sales we make to a third party whoThird-Party PPA programs, in turn, sells electricity through one of its own power purchase agreement programs of which we have no equity interest. The salesinvestment and we recognize revenue on acceptance.
For further information about our Power Purchase Agreement Programs, see Note 12 - Power Purchase Agreement Programs, to our consolidated financial statements included in this Quarterly Report on Form 10-Q.

With our Bloom Electrons program, we endeavored to assist our customers' purchases by directly participating in financing the purchase of their Energy Server. More recently, we have moved to providing the same service to our Energy Serverscustomers without our direct involvement in the capital financing and therefore, having no equity investment in the resulting PPA. We refer to the third party entity have many ofthis purchase option as Third-Party PPA arrangements, structured in a near-identical manner and with the same terms and conditions as a standard sale, as described above. We refer to these arrangements as Third-Party PPA Entities. The substantial majority of sales made as direct purchases in recent periods are pursuant to Third-Party PPA Entities finance arrangements. Payment for the purchase of our product is generally broken down into multiple installments, which may include payments upon signing of the purchase agreement, within 180 days prior to shipment, upon shipment of the Energy Server, and upon acceptance of the Energy Server. Acceptance typically occurs when the Energy Server is installed and running at full power as defined in each contract. A one-year service warranty is provided with the initial sale. After the expiration of the initial one-year warranty, customers have the option to enter into annual operations and maintenance services agreements with us at a price determined at the time of purchase of the Energy Server, which may be renewed each year for up to 20 years. Pursuant to the service warranty, we warrant minimum efficiency and output levels. In the event that the Energy Servers fail to satisfy these warranty levels, we may be obligated to repurchase the applicable Energy Servers if we are unable to repair or replace during the applicable cure period. Across all service agreements, including purchase and lease programs, as of June 30, 2018, we have incurred no repurchase obligations pursuant to such warranties. In addition, in some cases, we guarantee minimum output and efficiency levels greater than the warranty levels and pay certain capped performance guarantee amounts if those levels are not achieved. These performance guarantees are

negotiated on a case-by-case basis, but we typically provide an Output Guaranty of 95% measured annually and an Efficiency Guaranty of 52% measured cumulatively from the date the applicable Energy Server(s) are commissioned. In each case, underperformance obligates us to make a payment to the owner of the Energy Server(s). The fleet of Energy Servers deployed pursuant to purchase agreements performed at an average output of approximately 86% for three and six months ended June 30, 2018, and a lifetime average efficiency of approximately 52% through June 30, 2018. As of June 30, 2018, our obligation to make payments for underperformance on the direct purchase projects was capped at an aggregate total of approximately $54.7 million (including payments both for low output and for low efficiency). As of June 30, 2018, our aggregate remaining potential liability under this cap was approximately $41.6 million.
Third-Party Power Purchase Agreement Programs (Third-Party PPAs)
In addition to our traditional lease, managed services, and Bloom Electrons programs, we also sell Energy Servers under power purchase agreements where the owner of the Energy Servers generating the electricity delivered to the end customer is a third party in which we have no equity interests. Under these Third-Party PPAs, we identify end customers, lead the negotiations with such end customers regarding the offtake agreements to purchase electricity, and then enter into an Energy Server sales and operations and maintenance agreement with the Third-Party PPA entity that will own the Energy Servers for the full term of the offtake agreement. In some cases, the applicable third-party owner assists with the identification of end customers, and the negotiation of the offtake agreements. The Third-Party PPA entity then enters into offtake agreements with the end customer, who purchases electricity from the Third-Party PPA Entity. Unlike our Bloom Electrons program we have no(described above), only without our assuming an equity ownershipposition in the entity that ownsPPA structure. This way, we retain the benefits for the marketability of our Energy Servers without the capital burden and without the potential financial liability.
Lease Programs
In our Lease Programs, we sell the Energy Servers, and thus the third-party owner receives all cash flows generated under the offtake agreement(s), all investment tax credits, all accelerated tax depreciation benefits, and any other cash flows generated by the operation ofServer to a financing party that in turn leases the Energy Servers. InServer to the fourth quarter of 2016, we secured a commitment from a major utility company to finance up to 50 MW of Energy Server deployments under a Third-Party PPA; this commitment was subsequently expanded to an aggregate total of approximately 100.4 MW, of which we have deployed 48.0 MW as of June 30, 2018. Additionally, we have established a second Third-Party PPA with another major utility company; while this second program does not include a firm commitment as to total financing capacity, it permits the inclusion of sub-investment grade end customers.
For example, we have been working with financing sources to arrange for additional third-party Power Purchase Agreement Program entities, one of which will need to be finalized in order for our customers to arrange financing so that we can complete our planned installations for 2018.
Obligations to Third-Party Owners of Energy Servers
In each Third-Party PPA, we and the applicable third-party ownercustomer. We then enter into an operations and maintenance agreement (O&M Agreement) similar to the O&M Agreements entered into under the Bloom Electrons program, which O&M Agreement may be renewed on an annual basis at the option of the third-party owner until the end of the term of the third-party owner’s offtake agreement(s) to purchase electricity, with its end customers for such project. These offtake agreements have a fifteen-year term, but in some cases the offtake agreement and related O&M Agreement may extend for up to twenty years.
Our obligations under the O&M Agreement include (i) designing, manufacturing, and installing the Energy Servers, and selling such Energy Servers to the Third-Party PPA entity, (ii) obtaining all necessary permits and other governmental approvals necessary for the installation and operation of the Energy Servers, and maintaining such permits and approvals throughout the term of the O&M Agreement, (iii) operating and maintaining the Energy Servers in compliance with all applicable laws, permits and regulations, (iv) satisfying the efficiency and output warranties set forth in such O&M Agreement and the offtake agreement(s) (Performance Warranties), and (v) complying with any specific requirements contained in the offtake agreement(s) with individual end-customer(s). The O&M Agreement obligates us to repurchase the Energy Servers in the event the Energy Servers fail to comply with the Performance Warranties or we otherwise breach the terms of the applicable O&M Agreement and we fail to remedy such failure or breach after a cure period, or in the event that an offtake agreement terminates as a result of any failure by us to comply with the applicable O&M Agreement. In some Third-Party PPAs, our obligation to repurchase Energy Servers extends to the entire fleet of Energy Servers installed pursuant to the applicable O&M Agreement in the event such failure affects more than a specified number of Energy Servers.
In some cases, we have also agreed to pay liquidated damages to the third-party owner in the event of delays in the manufacture and installation of Energy Servers, either in the form of a cash payment or a reduction in the purchase price for the applicable Energy Server(s). Both the upfront purchase price for the Energy Servers and the ongoing fees for our operations and maintenance are paid on a fixed dollar-per-kilowatt ($/kilowatt) basis.
The O&M Agreement for each Third-Party PPA project generally provides for the following performance and indemnity obligations:

Efficiency Obligations. We warrant to the applicable third-party owner that each Energy Server and/or the portfolio of Energy Servers sold to such entity will operate at an average efficiency level specified in the O&M Agreement, calculated over a period specified in the O&M Agreement following the commercial operations date of such Energy Server. In some cases, we are obligated to repair and replace Energy Servers that are unable to satisfy the Efficiency Warranty, or if a repair or replacement is not feasible, to repurchase such Energy Servers at the original purchase price, subject to adjustment for depreciation (“Efficiency Warranty”). In other cases, we are obligated to make a payment to compensate for the increased costs of procuring natural gas for the applicable Energy Server(s) resulting from the underperformance as against the warranted level, which payments are capped at a level specified in the applicable O&M Agreement (“Efficiency Guaranty”).
Output Obligations. In addition, we warrant that the Energy Servers will generate a minimum amount of electricity during specified periods of time.
Under O&M Agreements, our output obligations include: (i) the generation of a minimum amount of electricity, the failure of which obligates us to repair or replace the Energy Servers that are unable to satisfy such warranty, or if such repair or replacement is not feasible, to repurchase such Energy Servers at the original purchase price, subject to adjustment for depreciation (“Output Warranty”), and (ii) the generation of a minimum amount of electricity on a cumulative basis beginning on the commercial operations date of such Energy Server, the failure of which obligates us to make a payment to the applicable third-party owner based on the volume of the shortfall below the warranted level, subject to a liability cap specified in the applicable O&M Agreement (“Output Guaranty”). Satisfaction of the Output Warranty is measured on either a cumulative basis or in each calendar month or calendar quarter, as specified in the applicable O&M Agreement. In some Third-Party PPAs, these generation obligations are aggregated across the entire fleet of Energy Servers deployed pursuant to such project; in others, each Energy Server must satisfy the minimum generation obligations measured individually.
Indemnification of Performance Warranty Expenses Under Offtake Agreements. In addition to the efficiency and output obligations, we also have agreed to indemnify certain Third-Party PPA entities for any expenses it incurs to any of the end-customers resulting from failures of the applicable Energy Servers to satisfy any of the efficiency, output or other performance warranties set forth in the applicable offtake agreement(s). In addition, in the event that an offtake agreement is terminated by a customer as to any Energy Servers as a result of our failure to perform any of our obligations under the O&M Agreement, we are obligated to repurchase such Energy Server from the applicable Third-Party PPA owner for a repurchase price equal to the original purchase price, subject to adjustment for depreciation.
Administration of Third-Party PPA Projects. Unlike the Bloom Electrons program, we perform no administrative services in the Third-Party PPA projects.
Obligations to End Customers. While the counterparty to the offtake agreements under the Third-Party PPA program is the third-party owner, under the O&M Agreements we are obligated to perform each of the obligations of such third-party owner set forth in each offtake agreement with the end customer. As such, our obligations to the end customers under the Third-Party PPAs are in all material respects the same as our obligations to the end customers under the Bloom Electrons program.
Our Third-Party PPA programs have O&M agreements that provide for Efficiency Guarantees and Output Guarantees, subject to performance guarantee caps. The performance guarantees for our existing Third-Party PPA agreements are capped at $56.9 million. As of June 30, 2018, we have paid $0.2 million in performance guarantee payments under these Third-Party PPA programs leaving potential obligations under the performance guarantees of $56.7 million. In addition, the O&M agreements with these Third-Party PPA agreements have minimum warranty guarantees for efficiency and output. As of June 30, 2018, no warranty claims have been made under the O&M agreements for these Third-Party PPA agreements.
Over time we have also developed various lease programs with our financing partners to provide alternative financing options. These programs take the form of either (1) a traditional lease agreed directly with the financing partner or (2) managed services.
Traditional Lease
Under the traditional lease arrangement, the customer enters into a lease directly with a financing partner, which pays us for the Energy Servers pursuant to a sales agreement (a Bank Agreement, described below). We recognize product and installation revenue upon acceptance. After the standard one-year warranty period, our customers have almost always exercised the option to enter into operations and maintenance services agreements with us, under which we receive annual service payments from the customer. The price for the annual operations and maintenance services is set at the time we enter into the lease. The duration of our traditional leases ranges from 6 to 15 years.
Under a Bank Agreement, we are generally paid the full price of the Energy Servers as if sold as a purchase by the customer based on four milestones (on occasion negotiated with the customer, but in all cases equal to no less than 60% of the purchase price billed at the shipment milestone, described below). The four payment milestones are typically as follows:

(i) 15% upon execution of the bank’s entry into the lease with a customer, (ii) 25% on the day that is 180 days prior to delivery of the Energy Servers, (iii) 40% upon shipment of the Energy Servers, and (iv) 20% upon acceptance of the Energy Servers. The bank receives title to the Energy Servers upon installation at the customer site and the customer has risk of loss while the Energy Server is in operation on the customer’s site.
The Bank Agreement provides for the installation of the Energy Servers and includes a standard one-year warranty, which includes the performance guarantees described below, with the warranty offered on an annually renewing basis at the discretion of the customer. The customer must provide gas forpays the Energy Servers to operate.
Warranty Commitments. We typically provide (i)financing party a rent payment and pays us an “Output Warranty” to operate at or above a specified baseload output of the Energy Servers on a site,operations and (ii) an “Efficiency Warranty” to operate at or above a specified level of fuel efficiency. Both are measured on a monthly basis. Upon the applicable financing partner or its customer making a warranty claim for a failure of any ofmaintenance fee. In our warranty commitments,Lease programs we are then obligated to repair or replace the Energy Server, or if a repair or replacement is not feasible, to pay the customer an amount approximately equal to the net book value of the Energy Server, after which the Bank Agreement would be terminated. As of June 30, 2018, we have incurred no obligations to make payments pursuant to these warranty commitments.
Performance Guarantees. Our performance guarantees are negotiated on a case-by-case basis for projects deployed through the traditional lease program, but we typically provide an Output Guaranty of 95% measured annually and an Efficiency Guaranty of 52% measured cumulatively from the date the applicable Energy Server(s) are commissioned. In each case, underperformance obligates us to make a payment to the applicable customer. As of June 30, 2018, the fleet of Energy Servers deployed pursuant to the traditional lease programs are performing at a lifetime average output of approximately 91% and a lifetime average efficiency of approximately 55%. As of June 30, 2018, our obligation to make payments for underperformance against the performance guarantees for traditional lease projects was capped at an aggregate total of approximately $5.8 million (including payments both for low output and for low efficiency). As of June 30, 2018, our aggregate remaining potential liability under this cap was approximately $5.5 million.
Remarketing at Termination of Lease. At the end of any customer lease in the event the customer does not renew or purchase the Energy Servers, we may remarket any such Energy Servers to a third party, and any proceeds of such sale would be allocated between us and the applicable financing partner as agreed between themrecognize revenue at the time of such sale.the sale to the financing party, which typically occurs in connection with acceptance.
Managed Services Programs
UnderIn our managed services program,Managed Services Programs, we initially enter intosell the Energy Server to a masterfinancing party and simultaneously lease withthe Energy Server back from the financing partner, which holds title to the Energy Server. Once a customer is identified, weparty. We then enter into an additional operating lease with the financing partner and a serviceEnergy Server services agreement with the customer. The duration ofcustomer pays us a fixed payment equal to our managed services leases is currently 10 years. We begin to recognize revenue from the sale of the equipmentlease payment obligation to the financing partner onceparty. In some cases, the Energy Server has been accepted bycustomer may also pay us an operations and maintenance fee. In our Managed Services programs we recognize revenue at the customer. Undertime of the master lease, we then make operating lease paymentssale to the financing partner. Under the service agreementparty, which typically occurs in connection with the customer, there are two payment components: a monthly equipment fee calculated based on the size of the installation, which covers the amount of our lease payment, and a service payment based on the monthly output of electric power produced by the Energy Server.acceptance.
Our warranty commitments under the managed services option are substantially similar to those applicable to the traditional lease program described above. Our managed services deployments do not typically include any performance guarantees above the warranty commitments, but the customer’s payment to us includes a payment that is proportionate to the output generated by the Energy Server(s) and our pricing assumes service revenues at the 95% output level. Therefore, our service revenues are lower if output is less than 95% (and higher if output exceeds 95%). As of June 30, 2018, the fleet of Energy Servers deployed pursuant to the managed services program were performing at a lifetime average output of approximately 94%.
Power Purchase Agreement Programs
In 2010, we began offeringOur customers have the option to purchase electricity produced by our Energy Servers through Bloom Electrons, financing for oura financed offering which we refer to as a Power Purchase Agreement Programs. These programsProgram, whereby one or more parties are financed via special purpose investmentequity investors in financing the entities (the Investment Companies), which typically are majority-owned by third-party investors and by us as a minority investor. The Investment Companies own and are parent to the operating entities (the Operating Companies). The Operating Companies, together with the Investment Companies, represent the PPA Entities. The investors contribute cash to the PPA Entity in exchange for equity interests, providing funding for the PPA Entities tothat purchase the Energy Servers from us. As we identify end customers,Servers. The entity owning the PPA EntityEnergy Server then enters into an agreementagreements with the end customer pursuant to which the customer agrees to purchasepurchases the electric powerelectricity generated by the Energy Server at a specified rate per kilowatt hour for a specified term, which can range from 10 to 21 years. Each PPA Entity currently serves between one and nine customers. As with our purchase and leasing arrangements, the standard one-year warranty and

guarantees are included in thefixed price of the product to the PPA Entity. The PPA Entity typically enters into an operations and maintenance services agreement with us following the first year of service to extend the warranty services and performance guarantees. This service agreement has a term coincident with the term of the applicableper kilowatt-hour (kWh). Our Power Purchase Agreement Project and paid for on an annual basis byPrograms include both the PPA Entity. The aggregate amount of extended warranty services payments we expect to receive over the remaining term of the Power Purchase Agreement Projects was $447.2 million as of June 30, 2018.
The mix of orders between our Bloom Electrons financing program, which includes an equity investment by us and other purchase options is generally driven by customer preference. Whilein which we cannot predict with certainty in any given period how customers will choose to finance their purchase, we have observed that, more recently, customers tend to choose a financing option that more closely mirrors the customers’ monthly payment stream for electricity. Power purchase agreements (PPAs), including our Bloom Electrons financing program, provide for payment streams as monthly payments similar to those for grid electricity payments.
Product revenue associated with the sale of the Energy Servers under the PPAs that qualify as sales-type leases is recognized at the present value of the minimum lease payments, which approximate fair value, assuming all other conditions for revenue recognition noted above have also been met. Customer purchases financed by PPA Entities since 2014 have been accounted for as operating leases and the related revenue under those agreements have been recognized as electricityrecognize revenue as the electricity is produced, and paid for by the customer. Under eachour Third-Party PPA arrangement, while the end customer pays the PPA Entity over the life of the contract for the electricity consumed, the timing of cash receipts to us is similar to that of an end-user directly purchasing an Energy Server from us.
Under our Power Purchase Agreement Program financing arrangements, we and our Power Purchase Agreement Program equity investors (Equity Investors) contribute funds into a limited liability Investment Company, which is treated as a partnership for U.S. federal income tax purposes, and which owns the Operating Company that acquires Energy Servers. This Operating Company then contracts with us to operate and service the Energy Servers. The Operating Company sells the electricity produced to the end customers under PPAs. Any debt incurred by the PPA Entities is non-recourse to us. Cash generated by the electricity sales, as well as from any applicable government incentive programs, is used to pay operating expenses of the Operating Company (including the operations and maintenance services we provide) and to service the non-recourse debt, with the remaining cash flows distributed to the Equity Investors based on the cash distribution allocations agreed between us and the Equity Investors. For further information see Note 12 - Power Purchase Agreement Programs to our consolidated financial statements included in this Quarterly Report on Form 10-Q. The Equity Investors receive substantially all of the value attributable to the long-term recurring customer lease payments, investment tax credits, accelerated tax depreciation and, in some cases, other incentives until the Equity Investors receive their contractual rate of return. In some cases, after the Equity Investors receive their contractual rate of return, we expect to receive substantially all of the remaining value attributable to the long-term recurring customer payments and the other incentives. As of June 30, 2018, none of our customers under PPAs have defaulted on their payment obligations.
We currently operate five distinct PPA Entities. Three of these PPA Entities (PPA II, PPA IIIa and PPA IIIb) are flip structures and the remaining two (PPA IV and PPA V) are strategic long-term partnerships with the Equity Investor that do not flip during the term of the arrangements. Of the three PPA Entity flip structures, PPA II is based on the Equity Investor reaching an agreed upon internal rate of return (IRR) and PPA IIIa and PPA IIIb are based on the flip occurring at a fixed date in the future.
Since we elected to decommission PPA I and purchased the Equity Investor’s interest for $25.0 million in convertible debt, we will receive 100% of any remaining cash flows from PPA I. Prior to the decommissioning, we received cash flows from PPA I totaling $393.6 million related to the purchase of Energy Servers, distributions of incentive receipts, annual maintenance payments and monthly administrative services payments. Since the decommissioning through June 30, 2018, we have received $13.2 million from PPA I related to customer electricity billings. With respect to PPA II, we estimate that the Equity Investor will need to receive additional cash distributions of approximately $96.2 million to reach its target IRR at which point we will receive substantially all of the remaining value attributable to the long-term customer payments and other incentives. To achieve these cash distributions and the contractual internal rate of return to trigger the ownership flip, PPA II will need to generate additional aggregate revenue of approximately $383.8 million. Our PPA II contracts do not specify the date on which the flip is projected to occur; rather, the PPA II contracts set forth the conditions that will trigger the flip and define the parties’ respective rights and obligations before and after the occurrence of the flip. Based on the current contractual terms, we estimate that PPA II will flip on approximately June 30, 2028, assuming prior termination does not occur.
For PPA IIIa and PPA IIIb, the Equity Investors receive preferred distributions of 2% of their total cash investment through the flip date, a fixed date in the future, and are not dependent on additional earned amounts. In PPA IIIa and IIIb, the flip dates are January 1, 2020 and January 1, 2021, respectively, and the remaining preferred distributions to be paid through the flip dates are $1.5 million and $1.2 million, respectively. We will receive substantially all of the remaining income (loss), tax and tax allocations attributable to the long-term customer payments and other incentives after each flip date.

Even after the occurrence of the flip date for PPA II, PPA IIIa and PPA IIIb, we do not anticipate subsequent distributions to us from the PPA Entities to be material enough to support our ongoing cash needs, and therefore we will still need to generate significant cash from product sales.
The Energy Servers purchased by the PPA Entities are recorded as property, plant and equipment and included within our consolidated balance sheets. We then reduce these assets by the amounts received by the Equity Investors from U.S. Treasury grants and the associated incentive rebates. In turn, we recognize the incentive rebates and subsequent customer payments as electricity revenue over the customer lease term and amortize U.S. Treasury grants as a reduction to depreciation of the associated Energy Servers over the term of the PPA. Since our inception, government incentives have accounted for approximately 13% of the expected total cash flows for all PPA Entities. As of June 30, 2018, our PPA Entities had received a total of $282.9 million in government grants and rebates.
We have determined that we are the primary beneficiary in these investment entities. Accordingly, we consolidate 100% of the assets, liabilities and operating results of these entities, including the Energy Servers and lease income, in our consolidated financial statements. We recognize the investors’ share of the net assets of the investment entities as noncontrolling interests in subsidiaries in our consolidated balance sheet. We recognize the amounts that are contractually payable to these investors in each period as distributions to noncontrolling interests in our consolidated statements of convertible redeemable preferred stock and equity. Our consolidated statements of cash flows reflect cash received from these investors as proceeds from investments by noncontrolling interests in subsidiaries. Our consolidated statements of cash flows also reflect cash paid to these investors as distributions paid to noncontrolling interests in subsidiaries. We reflect any unpaid distributions to these investors as distributions payable to noncontrolling interests in subsidiaries on our consolidated balance sheets.
All five PPA Entities have utilized their entire available financing capacity and completed their purchases of Energy Servers as of June 30, 2018.
Through our Bloom Electrons financing program, a total of approximately $1.1 billion in financing has been funded through June 30, 2018, including approximately $609.2 million in equity investments and an additional $448.7 million in non-recourse debt to support an aggregate deployment of approximately 106.8 megawatts of Energy Servers as of June 30, 2018. Equity Investors in our PPA Entities include banks and other large companies such as Credit Suisse, Exelon Generation Company, Intel Corporation and U.S. Bancorp. In the future, in addition to or in lieu of arranging customer financing through PPA Entities, we may use debt, equity or other financing strategies to fund our operations.
We view our obligations under Bloom Electrons in four categories: first, our obligations to the relevant PPA Entity formed to own the Energy Servers and sell electricity generated by such Energy Servers to the end-customers; second, the Project Company’s obligations to the lenders of such Project Company, if any; third, our obligations to the Equity Investors in the applicable project; and fourth, to the end-customers. We discuss these obligations in further detail below.
Obligations to PPA Entities
In each Power Purchase Agreement Project, we and the applicable PPA Entity enter into two primary contracts: first, a contract for the purchase, sale, installation, operation and maintenance of the Energy Servers to be employed in such PPA project (the O&M Agreement), and second, a contract whereby we are engaged to perform administrative functions for the PPA project during the term of the PPA project (the Administrative Services Agreement, or ASA). The O&M Agreement and the ASA each have a term coincident with the term of the applicable PPA project. The aggregate amount of extended warranty services payments we expect to receive under the O&M Agreement over the remaining term of the PPA projects was $447.2 million as of June 30, 2018. The aggregate amount of ASA payments we expect to receive over the remaining term of the PPA projects was $34.0 million as of June 30, 2018.
Our obligations to the PPA Entities pursuant to the O&M Agreement include: (i) designing, manufacturing, and installing the Energy Servers, and selling such Energy Servers to the PPA Entity, (ii) obtaining all necessary permits and other governmental approvals necessary for the installation and operation of the Energy Servers, and maintaining such permits and approvals throughout the term of the O&M Agreement, (iii) operating and maintaining the Energy Servers in compliance with all applicable laws, permits and regulations, (iv) satisfying the efficiency and output obligations set forth in such O&M Agreement (Performance Warranties), and (v) complying with any specific requirements contained in the offtake agreements with individual end-customers. The O&M Agreement obligates us to repurchase the Energy Servers in the event the Energy Servers fail to comply with the Performance Warranties and we fail to remedy such failure after a cure period, or in the event that an offtake agreement terminates as a result of any failure by us to comply with the requirements contained therein. In some cases, we have also agreed to pay liquidated damages to the PPA Entity in the event of delays in the manufacture and installation of Energy Servers. Both the upfront purchase price for the Energy Servers and the ongoing fees for our operations and maintenance are paid on a fixed dollar per kilowatt ($/kW) basis.

The O&M Agreements for each PPA Entity generally provide for the following Performance Warranties and indemnity obligations:
Efficiency Warranty and Efficiency Guaranty. We warrant to the applicable PPA Entity that the Energy Servers sold to such entity will operate at an average efficiency level specified in the O&M Agreement, calculated either cumulatively from the commercial operations date of each Energy Server or during each calendar month. We are obligated to repair or replace Energy Servers that are unable to satisfy the Efficiency Warranty, or if a repair or replacement is not feasible, to repurchase such Energy Servers at a price specified in the applicable O&M Agreement. In the case of PPA II, if the aggregate average efficiency falls below the specified threshold, we are also obligated to make a payment to the PPA Entity equal to the increased expense resulting from such efficiency shortfall, subject to a cap on aggregate payments equivalent to the purchase price of all Energy Servers in the PPA II portfolio. During the period from September 2010 to June 30, 2018, no Energy Servers have been repurchased pursuant to any Efficiency Warranty and no payments have been made pursuant to the Efficiency Guarantees.
One-Month Output Warranty. In the case of PPA II, we also warrant that the PPA II portfolio of Energy Servers will generate a minimum amount of electricity in each calendar month, and we are obligated to repair or replace Energy Servers that fail to satisfy this warranty. If we determine that a repair or replacement is not feasible, we are obligated to repurchase such Energy Servers at the original purchase price. During the period from September 2010 to June 30, 2018, no Energy Servers have been repurchased and no payments have been made pursuant to a One-Month Output Warranty.
Quarterly Output Warranty. In the case of PPA IIIa, we also warrant that each of the applicable Energy Servers will generate a minimum amount of electricity in each calendar quarter, and we are obligated to repair or replace Energy Servers that fail to satisfy this warranty. If we determine that a repair or replacement is not feasible, we are obligated to repurchase such Energy Servers at the original purchase price, subject to adjustment for depreciation. In addition, we are obligated to make a payment to the PPA IIIa entity to make it whole for lost revenues resulting from the shortfall below the warranted level, subject to a cap on payments equal to ten percent (10%) of the purchase price of the Energy Servers in the PPA IIIa portfolio. If we fail to make any such warranty payments if and when due, then PPA IIIa may elect to require us to repurchase Energy Servers that fail such warranty at the original purchase price, subject to adjustment for depreciation. During the period from September 2010 to June 30, 2018, no Energy Servers have been repurchased pursuant to the Quarterly Output Warranty, and we have made payments in the aggregate amount of $0.2 million pursuant to the Quarterly Output Warranty.
Quarterly Output Guaranty. In the cases of PPA IIIb, PPA IV and PPA V, we also guarantee to the applicable PPA Entity that the applicable portfolio of Energy Servers will generate a minimum amount of electricity in each calendar quarter. In the event the applicable portfolio fails to satisfy this Output Guaranty, we are obligated to make a payment to the applicable PPA Entity to make it whole for lost revenues resulting from the shortfall below the guaranteed level, and such liability is uncapped. If we fail to make any such Output Guaranty payments if and when due, then the applicable PPA Entity may elect to require us to repurchase Energy Servers that fail such guaranty, at a price specified in the applicable
O&M Agreement and pursue other damages. During the period from September 2010 to June 30, 2018, no Energy Servers have been repurchased pursuant to a Quarterly Output Guaranty, and we have made no payments pursuant to any Quarterly Output Guaranty.
Annual Output Guaranty. We also guarantee to the applicable PPA Entity that the applicable portfolio of Energy Servers will generate a minimum amount of electricity in each calendar year. In the event that such portfolio fails to satisfy this Output Guaranty, we are obligated to make a payment to the applicable PPA Entity to make it whole for lost revenues resulting from the shortfall below the warranted level, subject to a liability cap equal to a portion of the purchase price of the applicable portfolio. During the period from September 2010 to June 30, 2018, we have made payments in the aggregate amount of $23.5 million pursuant to these Output Guarantees. These payments were primarily as a result of performance issues in our early generation systems deployed in our first three PPA Entities (PPA I, PPA II & PPA IIIa). Of the aggregate amount of $23.5 million paid, $0.9 million was paid in the six months ended June 30, 2018, $3.7 million was paid in 2017, $4.8 million was paid in 2016, and $14.1 million was paid prior to 2016.
Indemnification of Performance Warranty Expenses under Offtake Agreements. In the cases of PPA IIIa, PPA IIIb, PPA IV and PPA V, we also have agreed to indemnify the applicable PPA Entity for any expenses it incurs to any of its customers resulting from failures of the applicable portfolio of Energy Servers to satisfy any of the efficiency, output or other performance commitments in the applicable offtake agreements. In addition, in the event that an offtake agreement is terminated by a customer as to any Energy Servers as a result of a default by us under the O&M Agreement, we are obligated to repurchase such Energy Server from the applicable PPA Entity for a repurchase price specified in the applicable O&M Agreement. During the period from September 2010 to June 30, 2018, we have incurred no obligations for payments pursuant to these provisions under any of our Power Purchase Agreement Program arrangements.

Our obligations pursuant to the ASA include performing a variety of administrative and management services necessary to conduct the business of the Power Purchase Agreement Program project. These duties include: (i) invoicing and collecting amounts due from the end-customers, (ii) engaging, supervising and monitoring any third-party service providers required for the operation of the project, (iii) paying, on behalf of the PPA Entity and with the PPA Entity’s available funds, any amounts owed, including debt service payments on the debt incurred by the PPA Entity (Project Debt), if applicable, (iv) maintaining books and records and preparing financial statements, (v) representing the PPA Entity in any administrative or other public proceedings, (vi) preparing annual budgets and other reports and deliverables owed by the PPA Entity under the Project Debt agreements, if applicable, and (vii) generally performing all other administrative tasks required in relation to the project. We receive an annual administration fee for its services, calculated on a fixed dollar per kilowatt ($/kW) basis.
Obligations to Lenders
Each of the Power Purchase Agreement Program projects (other than the PPA I project) has incurred debt in order to finance the acquisition of Energy Servers. The lenders for these projects are a combination of banks and/or institutional investors.
In each case, the Project Debt incurred by the applicable PPA Entity is secured by all of the assets comprising the project (primarily comprised of the Energy Servers owned by the PPA Entity and a collateral assignment of each of the contracts to which it is a party, including the O&M Agreement entered into with us and the offtake agreements entered into with PPA Entity’s customers), and is senior to all other debt obligations of the PPA Entity. As further collateral, the lenders receive a security interest in 100% of the membership interest of the PPA Entity. However, as is typical in structured finance transactions of this nature, although the Project Debt is secured by all of the PPA Entity’s assets, the lenders have no recourse to us or to any of the other Equity Investors in the project.
The applicable PPA Entity is obligated to make quarterly principal and interest payments according to an amortization schedule agreed between us, the Equity Investors and the lenders. The debt is either a “term loan”, where the final maturity date coincides with the expiration of the offtake agreements included in the project, or a “mini-perm loan,” where the final maturity date occurs at some point prior to such expiration; in the case of these “mini-perm loans”, we expect to be able to refinance these loans on or prior to their maturity date by procuring debt from other sources and using the proceeds of such new debt to repay the existing loans.
The Project Debt documentation also includes provisions that implement a customary “payment waterfall” that dictates the priority in which the PPA Entity will use its available funds to satisfy its payment obligations to us, the lenders, the Equity Investors and other third parties. These provisions generally provide that all revenues from the sale of electricity under the applicable offtake agreements and any other cash proceeds received by the PPA Entity are deposited into a “revenue account”, and those funds are then distributed in the following order: first, to pay for ongoing project expenses, including amounts due to us under the O&M Agreement and the ASA, taxes, insurance premiums, and any legal, accounting and other third party service provider costs; second, to pay any fees due to collateral agents and depositary agents, if any; third, to pay interest then due on the loans; fourth, to pay principal then due on the loans; fifth, to fund any reserve accounts to the extent not fully funded; and finally, any remaining cash (Distributable Cash) may be distributed to us and the Equity Investors in the project, subject to the satisfaction of any conditions to distributions agreed with the applicable lenders, such as a minimum debt service coverage ratios, absence of defaults, and similar requirements. Additional information regarding the Project Debt for each individual project is set forth in the Liquidity and Capital Resources section below. In addition, the “Distribution Conditions” are negotiated individually for each project, but in each case include (i) absence of defaults, and (ii) satisfaction of minimum debt service coverage ratios. In the event that there is Distributable Cash remaining after the payment of all higher-priority payment obligations but the applicable Distribution Conditions are not satisfied, the applicable funds are deposited into a “Distribution Suspense Account” and remain in such account until the Distribution Conditions are subsequently satisfied. In the event that any funds have been on deposit in the Distribution Suspense Account for four (4) consecutive calendar quarters, the applicable Project Company is obligated to use such “Trapped Cash” to prepay the Project Debt.
In connection with the PPA IIIb, PPA IV and PPA V projects, we procured a Fuel Cell Energy Production Insurance Policy on behalf of the applicable PPA Entity and the lenders (Production Insurance). The Production Insurance policies are intended to mitigate the risk of our failure or inability to operate and maintain the applicable portfolio of Energy Servers in accordance with the requirements of the O&M Agreement, and provides for debt service payment on the Project Debt in the event that the PPA Entity’s revenues are insufficient to make such payments due to a shortfall in the electricity generated by the Energy Servers. To date, no claims have been made under any of the Production Insurance policies.


Obligations to Investors
Each of our Power Purchase Agreement Projects has involved an investment by one or more Equity Investors, who contribute funds to the applicable PPA Entity in exchange for equity interests entitling such investors to distributions of the cash and any tax credits and other tax benefits generated by the project. In each of the projects, we (via a wholly-owned subsidiary) and one or more additional Equity Investors form a jointly-owned special purpose entity (each, a Holding Company), which entity in turn owns 100% of the membership interests of the applicable PPA Entity. Our obligations to the Equity Investors are set forth in the Holding Company limited liability company operating agreement (the Operating Agreement). We act as the managing member of each Holding Company, managing its day-to-day affairs subject to consent rights of the Equity Investors with respect to decisions agreed between us and the Equity Investors in the Operating Agreement.
As members of a Holding Company, we and the applicable Equity Investors are entitled to (i) allocations of items of income, loss, gain, deduction and credit (Tax Items) including, where applicable, the 30% investment tax credit under Section 48 of the Internal Revenue Code, and (ii) distributions of any cash held by such Holding Company in excess of amounts necessary for the ongoing operation of such Holding Company, including any Distributable Cash received from the applicable PPA Entity. The members’ respective allocations of Tax Items and cash distributions are negotiated on a project-by-project basis between us and the Equity Investors in each project. Distributions are made to Equity Investors (including us) on a quarterly basis in connection with PPA II, PPA IV and PPA V, and on a semi-annual basis in PPA IIIa and PPA IIIb.
In the event of a bankruptcy of a PPA Entity, the assets of such PPA Entity would be liquidated, likely at the direction of the bankruptcy trustee, if one was appointed, or according to the direction of the applicable lenders to such PPA Entity. In the event of a bankruptcy or liquidation, assets would first be liquidated to repay the applicable project’s debt. If any cash remained following the repayment of debt, such cash would be distributed among us and the Equity Investor(s) in the project in accordance with the applicable LLC agreement for the Investment Company. As a general matter, cash is first applied to the payment of owed but unpaid preferred distributions to the Equity Investor(s) other than us, if any, with any remaining assets split between us and such Equity Investor(s) in accordance with the sharing percentages of distributions as set forth in the applicable LLC agreement.
The Power Purchase Agreement Project agreements do not permit for voluntary early termination of the arrangements by us or the applicable Equity Investors. The Equity Investors in the projects may not withdraw from the applicable PPA Entity, except in connection with a permitted transfer or sale of such member’s assets in compliance with any restrictions on transfer set forth in the limited liability company agreement applicable to such project.
The following sets forth a project-by-project summary of obligations that are unique to individual projects:
PPA II. Diamond State Generation Partners, LLC (PPA Company II) is a wholly-owned subsidiary of Diamond State Generation Holdings, LLC (PPA II HoldCo), which is jointly-owned by us and an Equity Investor. As of June 30, 2018, we owned 100% of the Class A Membership Interests of PPA II HoldCo, and the Equity Investor owned 100% of the Class B Membership Interests of PPA II HoldCo. We (through our wholly-owned subsidiary Clean Technologies II, LLC), act as the managing member of PPA II HoldCo.
The economic benefits of the PPA II project are allocated between us and the Equity Investor as follows:
Other than Tax Items relating to the proceeds of any cash grant under Section 1603 of the American Recovery and Reinvestment Tax Act of 2009 (Cash Grant), Tax Items are allocated (i) 99% to the Equity Investor and 1% to us until the last date of the calendar month in which the Equity Investor has achieved an internal rate of return equal to the “Target IRR” specified in the PPA II HoldCo operating agreement (Flip Date), and (ii) following the Flip Date, 5% to the Equity Investor and 95% to us.
All Tax Items relating to the Cash Grant are allocated 99% to the Equity Investor and 1% to us.
All cash proceeds of the Cash Grant are distributed 99% to the Equity Investor and 1% to us.
All other cash available for distribution is distributed (i) 99% to the Equity Investor and 1% to us until the Flip Date, and (ii) following the Flip Date, 5% to the Equity Investor and 95% to us.
Pursuant to the PPA II HoldCo LLC agreement, we have the option, exercisable at our sole discretion, to purchase all of the Equity Investor’s membership interests in PPA II HoldCo on the eleventh anniversary of the date of the initial equity investment of the PPA II project by the Equity Investor, which will occur in June, 2023. If we were to exercise this purchase option, we would thereafter be entitled to all subsequent cash, income (loss), tax and tax allocations generated by the PPA II Project (net of payments to the PPA II lenders under the PPA II Credit Agreement) and the purchase price for the Equity Investor’s membership interests would be equal to the greater of (i) the fair market value of such equity interests at such time, or (ii) the amount that would cause the Equity Investor to realize an internal rate of return stated in the PPA II HoldCo LLC agreement. The cash consideration required to generate the required internal rate of return for the Equity Investor pursuant to this purchase option will vary based on the distributions generated by the PPA II Project thru June, 2023, and may range

between approximately $73.4 million and $137.4 million. We have agreed to indemnify the Equity Investor in PPA II HoldCo from any liability related to recapture of the Cash Grant, except to the extent such recapture results from (i) a breach of applicable representations and covenants of the Equity Investor, or (ii) a prohibited transfer of the Equity Investor’s membership interests in PPA II HoldCo.
The PPA II project includes an annual Output Guaranty of 95% and a cumulative Efficiency Guaranty of 50%. In each case, underperformance obligates us to make a payment to PPA Company II. As of June 30, 2018, the PPA II project is operating at an average output of approximately 86% for calendar year 2018, and a lifetime average efficiency of approximately 51%. Our obligation to make payments for underperformance of the PPA II project is capped at an aggregate total of approximately $13.9 million under the Output Guaranty and approximately $263.6 million under the Efficiency Guaranty. As of June 30, 2018, we have no remaining liability under the Output Guaranty, and our remaining potential liability under the Efficiency Guaranty cap is approximately $263.6 million.
Obligations Under the PPA II Tariff Agreement
PPA Company II is required to declare a “Forced Outage Event” if permitted under the PPA II tariff agreement in the event that (i) the Company has reached its cap on performance warranty payments under the O&M Agreement, such that PPA Company II is not eligible for further warranty payments under such O&M Agreement, (ii) the project’s lifetime efficiency falls below the level warranted in the O&M Agreement and the Company has not reimbursed PPA Company II for the resulting excess costs of procuring natural gas resulting from such shortfall, (iii) the Energy Servers have failed to generate electricity at an average above a minimum threshold specified in the PPA II Credit Agreement (i.e., 85% of the project’s nameplate capacity during any calendar month) or (iv) the Company has suffered a bankruptcy event or the Company ceases to carry on its business. As of June 30, 2018, no “Forced Outage Event” had been declared. The PPA II project’s average output for June 2018 equaled 86.0% of the project’s nameplate capacity.
In addition, in the event that PPA Company II claims that a “Forced Outage Event” has occurred under the PPA II tariff, PPA Company II is obligated to purchase and deliver replacement RECs in an amount equal to the number of megawatt hours for which it receives compensation under the ‘forced outage’ provisions of the tariff, but only if such replacement RECs are available in sufficient quantities and can be purchased for less than $45 per REC. A “Forced Outage Event” is defined under the PPA II tariff agreement as the inability of PPA II to obtain a replacement component part or a service necessary for the operation of the Energy Servers at their nameplate capacity. The PPA II tariff agreement provides for payments to PPA Company II in the event of a Forced Outage Event lasting in excess of 90 days. For the first 90 days following the occurrence of a Forced Outage Event, no payments are made under this provision of the tariff. Thereafter, PPA Company II is entitled to payments equal to 70% of the payments that would have been made under the tariff but for the occurrence of the Forced Outage Event-that is, the “Forced Outage Event” provision of the PPA II tariff agreement provides for payments to PPA Company II under the tariff equal to the amount that would be paid were PPA Company II’s Energy Servers operating at 70% of their nameplate capacity, irrespective of actual output. The PPA II tariff agreement also provides that the “Forced Outage Event” protections afforded thereunder shall automatically terminate in the event that we obtain anequity investment grade rating. In addition, in the event we obtain an investment grade rating, we are required to offer to repurchase the Notes from each individual noteholder unless we provide a guarantee of the debt obligations of the PPA Company II.
The Equity Investor in PPA II HoldCo has the option, exercisable on March 16, 2022, to sell 100% of its equity interests in the project to us for a sale price equal to the then-applicable fair market value of such equity interests. We guarantee the obligations of Clean Technologies II to make the payment of such purchase price in the event the Equity Investor exercises such option.
PPA IIIa. 2012 ESA Project Company, LLC (PPA Company IIIa) is a wholly-owned subsidiary of 2012 V PPA Holdco, LLC (PPA IIIa HoldCo), which is jointly-owned by us and an Equity Investor. As of June 30, 2018, we owned 100% of the Class B Membership Interests of PPA IIIa HoldCo, and the Equity Investor owned 100% of the Class A Membership Interests of PPA IIIa HoldCo. We (through our wholly-owned subsidiary Clean Technologies III, LLC), act as the managing member of PPA IIIa HoldCo.
The economic benefits of the PPA IIIa project are allocated between us and the Equity Investor as follows:

Cash available for distribution is distributed (i) until January 1, 2020, first, to the Equity Investor, a payment equal to 2% of the investor’s investment on an annual basis, and next, all remaining amounts are distributed to us; and (ii) from and after January 1, 2020, first, to the Equity Investor, a payment equal to 2% of the Equity Investor’s investment on an annual basis, and next, all remaining amounts are distributed 95.05% to us and 4.95% to the Equity Investor.

Pursuant to the PPA IIIa HoldCo LLC agreement, we have the option, exercisable at our sole discretion, to purchase all of the Equity Investor’s membership interests in PPA IIIa HoldCo, exercisable within six months following either January 1, 2020 or January 1, 2025. If we were to exercise this purchase option, we would thereafter be entitled to all subsequent cash, income (loss), tax and tax allocations generated by the PPA IIIa Project (net of payments to the PPA IIIa lenders under the PPA IIIa Credit Agreement) and the purchase price for the Equity Investor’s membership interests would be equal to the greater of (i) the fair market value of such equity interests at such time, or (ii) the sum of (x) any unpaid amounts owed to the Equity Investor pursuant to its entitlement to cash distributions equal to 2% of its investment (as described above), plus (y) approximately $2.1 million. The PPA IIIa project includes (i) an Output Guaranty of 95% measured annually, (ii) an Output Warranty of 80% measured quarterly, (iii) an Efficiency Warranty of 45% measured monthly, and (iv) an indemnity of any payments made by PPA Company IIIa regarding failure of the Energy Servers to perform in accordance with the applicable offtake agreements, which generally provide for an Efficiency Guaranty of 52% measured cumulatively over the life of the project. In the case of underperformance with respect to the Output Warranty and/or the Output Guaranty, we are obligated to make a payment to PPA Company IIIa; additionally, in the case of underperformance against the Output Warranty, we are obligated to repair or replace the applicable Energy Servers. In the case of underperformance with respect to the Efficiency Warranty, we are obligated to repair or replace the applicable Energy Servers, and we are obligated to reimburse PPA Company IIIa for any payments owed to the applicable customer(s). As of June 30, 2018, the PPA IIIa project is operating at an average output of approximately 85% for calendar year 2018, an average output of approximately 85% for the three months ended June 30, 2018 and a lifetime average efficiency of approximately 52%. Our obligation to make payments for underperformance of the PPA IIIa project is capped at an aggregate total of approximately $5.0 million under the annual Output Guaranty, approximately $10.0 million under the quarterly Output Warranty, and approximately $675,000 under the Efficiency Guarantees in the applicable offtake agreements. As of June 30, 2018, our aggregate remaining potential liability under these caps is approximately $2.4 million under the annual Output Guaranty, approximately $9.8 million under the quarterly Output Warranty, and approximately $675,000 under the Efficiency Guarantees.
We have agreed to indemnify the Equity Investor in PPA IIIa HoldCo from any liability related to recapture of the ITC except to the extent such recapture results from (i) a transfer of the Equity Investor’s membership interest in the project, (ii) a change in the federal income tax classification of the Equity Investor or its owners, (iii) a change in federal income tax law or (iv) adverse findings regarding the tax classification of the project.
The Equity Investor has the option, exercisable for a six month period commencing January 1, 2021, to withdraw from PPA IIIa HoldCo by notice to us. Notwithstanding the allocations of cash available for distribution set forth above, in the event that the Equity Investor exercises this withdrawal option, such investor shall receive 99% of the cash available for distribution until it has received the fair market value of its Class A Membership Interests in PPA IIIa HoldCo at such time, but in any event no more than approximately $2.0 million.
PPA IIIb. 2013B ESA Project Company, LLC (PPA Company IIIb) is a wholly-owned subsidiary of 2013B ESA Holdco, LLC (PPA IIIb HoldCo), which is jointly-owned by us and an Equity Investor.

The final payment for developer fee liabilities was made in 2017, and there are no liabilities recorded as of June 30, 2018.
Obligations to End-Customers
Our obligations to the end-customers in the Bloom Electrons projects are set forth in the offtake agreement between the PPA Entity and the end-customer. The offtake agreements share the following provisions:
Term; Early Termination: The offtake agreements provide for an initial term of 15 years, except that (i) the offtake agreements included in PPA I provide for an initial term of 10 years, and (ii) the offtake agreement for PPA II has a term of 21 years. The offtake agreements may be renewed by the mutual agreement of the end-customer and the applicable PPA Entity for additional periods at the expiration of the initial term. In the event that the end customer desires to terminate the offtake agreement before the end of the contract term, or in the event that the offtake agreement is terminated by the applicable PPA Entity due to customer default as defined in the offtake agreement, the end customer is required to pay a “termination value” payment as liquidated damages. This termination value payment is calculated to be sufficient to allow the PPA Entity to repay any debt associated with the affected Energy Servers, make distributions to the Equity Investor(s) in the project equal to their expected return on investment, pay for the removal of the Energy Servers from the project site, and cover any lost tax benefits incurred as a result of the termination (if any). In some cases, we may agree to reimburse the end-user for some or all of the termination value payments paid if we are able to successfully resell or redeploy the applicable Energy Servers following termination of the offtake agreement.
Energy Server Installation and Operation: The applicable PPA Entity is responsible for the installation, operation and maintenance of the Energy Servers. In performing such services, the PPA Entity is required to comply with all applicable laws and regulations, with the requirements of any permits obtained for the Energy Servers, with any requirements of the interconnection agreement entered into with the local electric utility regarding such Energy Servers, and with any requirements agreed with the applicable end-customer in the offtake agreement (such as site access procedures, black-out periods regarding routine maintenance, etc.).
Take-Or-Pay Purchase Obligation: The end-customer is required to purchase all of the electricity generated by the Energy Servers for the duration of the offtake agreement. We perform an initial credit evaluation of our customer’s ability to pay under the PPA arrangements. Subsequently, on an at least annual basis, we re-evaluate and confirm the credit worthiness of our customers. Under our existing Power Purchase Agreement Programs, there are four customers that represent more than 10% of the total assets of our PPA Entities. The four customers include Delmarva, Home Depot, AT&T and Walmart. In the event that an end-customer is unwilling or unable to accept delivery of such electricity or fails to supply the necessary fuel to the

Energy Servers (if applicable), the end-customer is required to make a payment to the PPA Entity for the amount of electricity that would have been delivered had the Energy Servers continued to operate.
Fuel Supply Obligation: In PPA I, fuel supply obligations are either the obligation of the PPA Entity or the end-customer, on a case-by-case basis. In PPA II, the PPA entity is responsible for providing all required fuel to the Energy Servers and is reimbursed pursuant to the Delmarva Tariff so long as the Energy Servers maintain a specified operational efficiency. In the PPA IIIa, PPA IIIb, PPA IV and PPA V projects, the end-customers are required to provide all necessary fuel for the operation of the Energy Servers.
Ownership of Energy Servers: The applicable PPA Entity retains title to the Energy Servers at all times unless the end-customer elects to purchase the Energy Server(s).
Financial Incentives and Environmental Attributes: As the owner of the Energy Servers, the PPA Entity retains ownership of any tax benefits associated with the installation and operation of the Energy Servers. Additional financial incentives available in connection with the offtake agreements (such as payments under state incentive programs or renewable portfolio standard programs) and any environmental benefits associated with the Energy Servers (such as carbon emissions reductions credits) are allocated to either the PPA Entity or the end-customer on a case-by-case basis. In some circumstances, the PPA Entity has also agreed to purchase and deliver to the end-customer renewable energy credits in connection with the offtake agreement.
Efficiency Commitments: Where the end-customer is responsible for delivering fuel to the Energy Servers, the offtake agreement includes Energy Server efficiency commitments. Generally, these consist of (i) an “Efficiency Warranty”, where the PPA Entity is obligated to repair or replace Energy Servers that fail to operate at or above a specified level of efficiency during any calendar month, and/or (ii) an “Efficiency Guaranty”, where the PPA Entity is obligated to make payments to the end-customer to cover the cost of procuring excess fuel if the Energy Servers fail to operate at or above a specified level of efficiency on a cumulative basis during the term of the offtake agreement. Where an Efficiency Guaranty is provided, the PPA Entity’s aggregate liability for payments is capped. In certain circumstances, we may negotiate modifications to the efficiency commitments with the end-customer, including different efficiency thresholds or providing for monetary payments under the Efficiency Warranty in lieu of or in addition to our obligation to repair or replace underperforming Energy Servers.
Output Commitments: Although our standard Bloom Electrons offering does not include a minimum output commitment to the end-user, exceptions may be negotiated on a case-by-case basis if we believe the opportunity justifies such exception. These output commitments are at an output level lesser than or equal to the level warranted by us to the PPA Entity under the O&M Agreement, and provide either for a payment to the end-customer for the shortfall in electricity produced or for an end-customer termination right. In addition, where the end-user (as opposed to the PPA Entity) is entitled to the benefits of an incentive program that requires a minimum output level, the PPA Entity may agree to reimburse the end-customer for any decrease in incentive payments resulting from the Energy Servers’ failure to operate at such minimum output level.
Defaults; Remedies: Defaults under the offtake agreements are typically limited to (i) bankruptcy events, (ii) unexcused failure to perform material obligations, and (iii) breaches of representations and warranties. Additional defaults may be negotiated on a case-by-case basis with end-customers. The parties are generally afforded cure periods of at least 30 days to cure any such defaults. In the event of an uncured default by the PPA Entity, the end-customer may terminate the offtake agreement either in whole or in part as to the Energy Server(s) affected by such default, and may seek other remedies afforded at law or in equity. In the event of an uncured default by the end-customer, the PPA Entity may terminate the offtake agreement either in whole or in part as to the Energy Server(s) affected by such default, and may seek other remedies afforded at law or in equity; in addition, in the event an offtake agreement is terminated due to an end-customer default, the end-customer is obligated to make a termination value payment to the PPA Entity.acceptance.
For further information about our PPA entities,Power Purchase Agreement Programs, see Note 12 - Power Purchase Agreement Programs, to our consolidated financial statements included in this Quarterly Report on Form 10-Q.

With our Bloom Electrons program, we endeavored to assist our customers' purchases by directly participating in financing the purchase of their Energy Server. More recently, we have moved to providing the same service to our customers without our direct involvement in the capital financing and therefore, having no equity investment in the resulting PPA. We refer to this purchase option as Third-Party PPA arrangements, structured in a near-identical manner and with the same terms and conditions as our Bloom Electrons program (described above), only without our assuming an equity position in the PPA structure. This way, we retain the benefits for the marketability of our Energy Servers without the capital burden and without the potential financial liability.
Lease Programs
In our Lease Programs, we sell the Energy Server to a financing party that in turn leases the Energy Server to the customer. We then enter into an operations and maintenance agreement with the customer. The customer pays the financing party a rent payment and pays us an operations and maintenance fee. In our Lease programs we recognize revenue at the time of the sale to the financing party, which typically occurs in connection with acceptance.
Managed Services Programs
In our Managed Services Programs, we sell the Energy Server to a financing party and simultaneously lease the Energy Server back from the financing party. We then enter into an Energy Server services agreement with the customer. The customer pays us a fixed payment equal to our lease payment obligation to the financing party. In some cases, the customer may also pay us an operations and maintenance fee. In our Managed Services programs we recognize revenue at the time of the sale to the financing party, which typically occurs in connection with acceptance.
Purchase Options
Depending upon the purchase option chosen by our customer, either the customer or the financing provider may utilize investment tax credits and other government incentives. However, the timing of the product-related cash flows to us is generally consistent across all of the purchase options. We generally receive all product-related payments by the time that the product is accepted by the end customer.
Our capacity to offer our Energy Servers through any of these arrangements depends in large part on the ability of the parties involved in providing payment for the Energy Servers to monetize the related investment tax credits, accelerated tax depreciation and other incentives, and/or the future power purchase obligations of the end customer. Interest rate fluctuations would also impact the attractiveness of any financing offerings for our customers, and currency exchange fluctuations may also impact the attractiveness of international offerings. The Traditional Lease, Managed Services and Power Purchase Agreement Program options are limited by the creditworthiness of the customer. Additionally, the Traditional Lease and Managed Services options, as with all leases, are also limited by the customer’s willingness to commit to making fixed payments regardless of the performance of the Energy Servers or our performance of our obligations under the customer agreement.
Under each purchase option, we provide warranties and performance guaranties for the Energy Servers’ efficiency and output. Under direct purchase, Traditional Lease, and Power Purchase Agreement Program options, the warranty and performance guaranty is typically included in the price of the Energy Server for the first year. The warranty and performance guaranty may be renewed annually at the customer’s option - as an operations and maintenance services agreement - at predetermined prices for a period of up to 25 years. Historically, our customers have almost always exercised their option to renew under these operations and maintenance services agreements. Under the Power Purchase Agreement Programs, we provide warranties and performance guaranties regarding the Energy Servers’ efficiency to the customer (i.e., the electricity user), and we provide warranties and performance guaranties regarding the Energy Servers’ output to the customer that purchases the Energy Servers. Additionally, under the Managed Services program, the operations and maintenance services agreements are priced separately and included for a fixed period specified in the customer agreement. This period is typically either 6 or 10 years, which may be extended at the option of the parties for additional years with all payments made annually.
Warranty Commitments - We typically provide (i) an output warranty to operate at or above a specified baseload output of the Energy Servers on a site, and (ii) an efficiency warranty to operate at or above a specified level of fuel efficiency. Both are measured on a monthly, cumulative, or other basis, as specified in the Financing Agreement or customer agreement, as applicable. Upon the applicable beneficiary making a warranty claim for a failure of any of our warranty commitments, we are then obligated to repair or replace the Energy Server, or if a repair or replacement is not feasible, to pay the customer an amount approximately equal to the net book value of the Energy Server, after which the Financing Agreement or customer agreement would be terminated.

Performance Guaranties - Our performance guaranties are negotiated on a case-by-case basis, but we typically provide (i) an output guaranty to deliver a specified amount of electricity, and (ii) an efficiency guaranty to operate at or about a specified level of fuel efficiency. The output guaranty and efficiency guaranty are each typically measured on a cumulative basis from the date the applicable Energy Server(s) are commissioned, but the measurement period may be subject to negotiations on a case-by-case basis. In each case, underperformance obligates us to make a payment to the applicable beneficiary, subject to a cap specified in the applicable agreement.
International Channel Partners
Prior to 2018, we consummated a small number of sales outside the United States of America, including in India and Japan. In India, sales activities are currently conducted by Bloom Energy (India) Pvt. Ltd., our wholly-owned indirect subsidiary; however, we are currently evaluating the Indian market to determine whether the use of channel partners would be a beneficial go-to-market strategy to grow our India market sales.
In Japan, sales are conducted pursuant to a Japanese joint venture established between us and subsidiaries of SoftBank Corp, called Bloom Energy Japan Limited ("Bloom Energy Japan"). Under this arrangement, we sell Energy Servers to Bloom Energy Japan and we recognize revenue once the Energy Servers leave the port of the U.S. as Bloom Energy Japan enters into the contract with the end customer and performs all installation work, as well as some of the operations and maintenance work.
In 2018, Bloom Energy Japan consummated a sale of Energy Servers into certain countries in the Asia Pacific region. Following this sale, we entered into a Preferred Distributor Agreement with SK Engineering & Construction Co., Ltd. to enable us to sell directly into the Asia Pacific region.

Key Operating Metrics
In addition to the measures presented in the consolidated financial statements, we use the following key operating metrics to evaluate business activity, to measure performance, to develop financial forecasts and to make strategic decisions:
Product accepted - the number of customer acceptances of our Energy Servers in any period. We recognize revenue when an acceptance is achieved. We use this metric to measure the volume of deployment activity. We measure each Energy Server manufactured, shipped and accepted in terms of 100 kilowatt equivalents.

Megawatts deployed - the aggregate megawatt capacity of operating Energy Servers in the field that have achieved acceptance. We use this metric to measure the total electricity-generating capacity of deployed Energy Servers, measured in megawatts.
Billings for product accepted in the period - the total contracted dollar amount of the product component of all Energy Servers that are accepted in a period. We use this metric to gauge the dollar value of the product acceptances and to evaluate the change in dollar amount of acceptances between periods.
Billings for installation on product accepted in the period - the total contracted dollar amount billable with respect to the installation component of all Energy Servers that are accepted. We use this metric to gauge the dollar value of the installations of our product acceptances and to evaluate the change in dollar value associated with the installation of our product acceptances between periods.
Billings for annual maintenance service agreements - the dollar amount billable for one-year service contracts that have been initiated or renewed.
Product costs of product accepted in the period (per kilowatt) - the average unit product cost for the Energy Servers that are accepted in a period. We use this metric to provide insight into the trajectory of product costs and, in particular, the effectiveness of cost reduction activities.
Period costs of manufacturing expenses not included in product costs - the manufacturing and related operating costs that are incurred to procure parts and manufacture Energy Servers that are not included as part of product costs. We use this metric to measure any costs incurred to run our manufacturing operations that are not capitalized (i.e., absorbed) into inventory and therefore, expensed to our consolidated statement of operations in the period that they are incurred.
Installation costs on product accepted (per kilowatt) - the average unit installation cost for Energy Servers that are accepted in a given period. This metric is used to provide insight into the trajectory of install costs and, in particular, to evaluate whether our installation costs are in line with our installation billings.
Key Operating Metrics -
Comparison of the Three Months Ended June 30March 31, 2019 and 2018
Acceptances
We use acceptances as a key operating metric to measure the volume of our completed sales operational activity from period to period. We typically define an acceptance as when an Energy Server is installed and running at full power as defined in the customer contract or the financing agreements. For orders where one of our partners performs the installation, acceptances are generally achieved when the Energy Servers are shipped.

Billings for product accepted increased approximately $43.1 million, or 66.8%, for the three months ended June 30, 2018, comparedThe portion of total revenue attributable to the three months ended June 30, 2017. The increase was primarily due to three factors.
First, product accepted increased approximately 19 systems, or 11.7%, for the three months ended June 30, 2018, compared to the three months ended June 30, 2017.

Second, ITC was reinstated on February 9, 2018. ITC was not available to the fuel cell industry in 2017, so our billings for product accepted in 2017 did not include the benefit of ITC. Due to the reinstatement of ITC in 2018, billings for product accepted now includes the benefit of ITC. For the three months ended June 30, 2018, billings for product accepted included $26.4 million of benefit from ITC.
Third, the adoption of customer personalized applications such as batteries and grid-independent solutions increasedeach purchase option in the three months ended June 30, 2018 compared to the three months ended June 30, 2017. Products that incorporate these personalized applications have, on average, a higher billings rate than our standard platform products that do not incorporate these personalized applications.
Billings for installation on product accepted remains relatively unchanged for the three months ended June 30, 2018, compared to the three months ended June 30, 2017. Despite an 11.7% increase in product acceptances, billings for installation on product accepted remains unchanged due to the mix in installation billings driven by site complexity, size and customer purchase option.
When we analyze changes between the three months ended June 30, 2018 and 2017, we take into account the impact of the ITC thatperiod was available in 2018 as a result of the reinstatement of the ITC. The effect of the reinstatement of ITC was higher billings in the periods eligible for ITC. ITC was extended through December 2021. For the three months ended June 30, 2018, the combined total billings for product and installation accepted was $133.3 million, an increase of 47.7% from the billings for product and installation accepted combined of $90.3 million for the three months ended June 30, 2017. The increase was significantly greater than the 11.7% increase in associated acceptances during the same periods due to the reinstatement of the ITC in 2018.
Billings for annual maintenance service agreements increased approximately $1.0 million, or 5.4%, for the three months ended June 30, 2018, compared to the three months ended June 30, 2017. This increase was driven by the billing for new maintenance contract renewals for a greater number of megawatts deployed.follows:

First, product accepted increased approximately 66 systems, or 23.5%, for the six months ended June 30, 2018, compared to the six months ended June 30, 2017.
Second, ITC was reinstated on February 9, 2018. ITC was not available to the fuel cell industry in 2017, so our billings for product accepted in 2017 did not include the benefit of ITC. Due to the reinstatement of ITC in 2018, billings for product accepted now includes the benefit of ITC. For the six months ended June 30, 2018, billings for product accepted includes $86.0 million in benefits from ITC, of which $45.1 million was retroactive ITC for 2017 acceptances.
Third, the adoption of customer personalized applications such as batteries and grid-independent solutions increased in the six months ended June 30, 2018 compared to the six months ended June 30, 2017. Products that incorporate these personalized applications have, on average, a higher billings rate than our standard platform products that do not incorporate these personalized applications.
Billings for installation on product accepted decreased by $11.1 million for the six months ended June 30, 2018, as compared to the six months ended June 30, 2017. Despite a 23.5% increase in product acceptances, billings for installation on product accepted decreased due to the mix in installation billings driven by site complexity, size, customer purchase option and one large customer in particular in the six months ended June 30, 2018 where the installation was performed by the customer, therefore, we did not have any installation billing for that customer.
When we analyze changes between the six months ended June 30, 2018 and 2017, we take into account the impact of ITC that was available in 2018 as a result of the reinstatement of the ITC. The effect of the reinstatement of ITC was higher billings in the periods eligible for ITC. ITC was extended through December 2021. For the six months ended June 30, 2018, the combined total for billings for product and installation accepted was $266.4 million, an increase of 65.0% from the billings for product and installation accepted combined of $161.4 million for the six months ended June 30, 2017. The increase was significantly greater than the 23.5% increase in associated acceptances during the same periods due to the reinstatement of the ITC in 2018.
Billings for annual maintenance service agreements remained substantially the same for the six months ended June 30, 2018, compared to the six months ended June 30, 2017.

Product costs of product accepted increased approximately $169 per kilowatt, or 4.8%, for the six months ended June 30, 2018, compared to the six months ended June 30, 2017. This increase in cost is primarily due to the increased adoption of customer personalized applications for the six months ended June 30, 2018. These customer personalized applications have a higher product cost on a per unit basis. A one-time impact of $271 per kilowatt was also included in the product cost of product accepted for the six months ended June 30, 2018 which was associated with supplier agreements that required us to forego previously negotiated discounts if ITC was renewed.
Period costs of manufacturing related expenses decreased approximately $2,307, or 14.3%, for the six months ended June 30, 2018, compared to the six months ended June 30, 2017. Our period costs of manufacturing related expenses decreased primarily due to higher absorption of fixed manufacturing costs due to higher factory utilization.
Installation costs on product accepted decreased approximately $313 per kilowatt, or 19.7%, for the six months ended June 30, 2018, compared to the six months ended June 30, 2017. This decrease in cost is primarily due to the change in mix of site complexity, size, customer purchase option and one large customer in particular in the six months ended June 30, 2018 where the installation was performed by the customer, therefore, we did not have any installation cost for that customer. This decrease in cost was partially offset by higher installation cost driven by increased adoption of customer personalized applications for the six months ended June 30, 2018 as mentioned above. These customer personalized applications also have a higher install cost on a per unit basis.
Results of Operations
Revenue
We primarily recognize revenue from the sale and installation of Energy Servers, by providing services under maintenance contracts and electricity sales to our PPA Entities.
Product Revenue
All of our product revenue is generated from the sale of our Energy Servers to direct purchase, traditional lease and managed services customers. We generally recognize product revenue from contracts with customers for the sales of our Energy Servers once we achieve acceptance; that is, generally when the system has been installed and running at full power as defined in each contract.
The amount of product revenue we recognize in a given period is materially dependent on the volume and size of installations of our Energy Servers and on the type of financing used by the customer.
Installation Revenue
All of our installation revenue is generated from the installation of our Energy Servers to direct purchase, traditional lease and managed services customers. The amount of installation revenue we recognize in a given period is materially dependent on the volume and size of installations of our Energy Servers in a given period and on the type of financing used by the customer.
Service Revenue
Service revenue is generated from operations and maintenance services agreements that extend the standard one-year warranty service coverage beyond the initial one-year coverage for Energy Servers sold under direct purchase, traditional lease and managed services sales. Customers of our purchase and lease programs can renew their operating and maintenance services agreements on an annual basis for the lifeComparison of the contract at prices predetermined at the time of purchase of the Energy Server. We anticipate that almost all of our customers will continue to renew their operations and maintenance services agreements each year.

Electricity Revenue
Our PPA Entities purchase Energy Servers from us and sell the electricity produced by these systems to customers through long-term PPAs. Customers are required to purchase all of the electricity produced by the Energy Servers at agreed-upon rates over the course of the PPA’s term. We generally recognize revenue from such PPA Entities as the electricity is provided over the term of the agreement.
Cost of Revenue
Our total cost of revenue consists of cost of product revenue, cost of installation revenue, cost of service revenue and cost of electricity revenue. It includes personnel costs associated with our operations and global customer support organizations consisting of salaries, benefits, bonuses, stock-based compensation and allocated facilities costs.
Cost of Product Revenue
Cost of product revenue consists of costs of Energy Servers that we sell to direct, traditional lease and managed services customers, including costs of materials, personnel costs, allocated costs, shipping costs, provisions for excess and obsolete inventory and the depreciation costs of our equipment. Because the sale of our Energy Servers includes a standard one-year warranty, cost of product revenue also includes estimated first-year warranty costs. Warranty costs for customers that purchase under managed services or the Bloom Electrons program are recognized as a cost of product revenue as they are incurred. We expect our cost of product revenue to increase in absolute dollars as we deliver and install more Energy Servers and our product revenue increases.
Cost of Installation Revenue
Cost of installation revenue consists of the costs to install the Energy Servers that we sell to direct, traditional lease and managed services customers, including costs of materials and service providers, personnel costs, and allocated costs. We expect our cost of installation revenue to increase in absolute dollars as we deliver and install more Energy Servers, though it will be subject to variability as a result of the foregoing.
Cost of Service Revenue
Cost of service revenue consists of costs incurred under maintenance service contracts for all customers including direct sales, traditional lease, managed services and PPA customers. Such costs include personnel costs for our customer support organization, allocated costs and extended maintenance-related product repair and replacement costs. We expect our cost of service revenue to increase in absolute dollars as our end-customer base of megawatts deployed grows, and we expect our cost of service revenue to fluctuate period by period depending on the timing of maintenance of Energy Servers.
Cost of Electricity Revenue
Cost of electricity revenue primarily consists of the depreciation of the cost of the Energy Servers owned by our PPA Entities and the cost of gas purchased in connection with PPAs entered into by our first PPA Entity. The cost of depreciation of the Energy Servers is reduced by the amortization of any U.S. Treasury grant payment in lieu of the energy investment tax credit associated with these systems. We expect our cost of electricity revenue to increase in absolute dollars as our end-customer base of megawatts deployed grows.
Gross Profit (Loss)
Gross profit (loss) has been and will continue to be affected by a variety of factors, including the sales price of our products, manufacturing costs, the costs to maintain the systems in the field, the mix of financing options used, and the mix of revenue between product, service and electricity. We expect our gross profit to fluctuate over time depending on the factors described above.
Operating Expenses
Research and Development
Research and development costs are expensed as incurred and consist primarily of personnel costs. Research and development expense also includes prototype related expenses and allocated facilities costs. We expect research and development expense to increase in absolute dollars as we continue to invest in our future products and services, and we expect our research and development expense to fluctuate as a percentage of total revenue.

Sales and Marketing
Sales and marketing expense consists primarily of personnel costs, including commissions. We expense commission costs as earned. Sales and marketing expense also includes costs for market development programs, promotional and other marketing costs, travel costs, office equipment and software, depreciation, professional services and allocated facilities costs. We expect sales and marketing expense to continue to increase in absolute dollars as we increase the size of our sales and marketing organizations and to expand our international presence, and we expect our sales and marketing expense to fluctuate as a percentage of total revenue.
General and Administrative
General and administrative expense consists of personnel costs, fees for professional services and allocated facilities costs. General and administrative personnel include our executive, finance, human resources, information technology, facilities, business development and legal organizations. We expect general and administrative expense to increase in absolute dollars due to additional legal fees and costs associated with accounting, insurance, investor relations, SEC and stock exchange compliance and other costs associated with being a public company, and we expect our general and administrative expense to fluctuate as a percentage of total revenue.
Stock-Based Compensation
We typically record stock-based compensation expense under the straight-line attribution method over the vesting term, which is generally five years, and record stock-based compensation expense for performance based awards using the graded-vesting method. Stock-based compensation expense is recorded net of estimated forfeitures such that expense is recorded only for those stock-based awards that are expected to vest. Stock-based compensation expense is recorded in the consolidated statements of operations based on the employees’ respective function.
Interest Expense
Interest expense primarily consists of interest charges associated with our secured line of credit, long-term debt facilities, financing obligations and capital lease obligations. We expect interest charges to decrease as a result of pay-downs of the debt obligations over the course of the debt arrangements.
Other Income (Expense), Net
Other expense, net primarily consists of gains or losses associated with foreign currency fluctuations, net and of income earned on our cash and cash equivalents holdings in interest-bearing accounts. We have historically invested our cash in money-market funds.
Gain/Loss on Revaluation of Warrant Liabilities
Warrants issued to investors and lenders that allow them to acquire our convertible preferred stock have been classified as liability instruments on our balance sheet. We record any changes in the fair value of these instruments between reporting dates as a separate line item in our statement of operations. As some of the warrants issued are mandatorily convertible to common stock subsequent to the completion of our IPO, they will no longer be recorded as a liability related to these mandatorily converted warrants.
Provision for Income Taxes
Provision for income taxes consists primarily of federal and state income taxes in the United States and income taxes in foreign jurisdictions in which we conduct business. We have provided a full valuation allowance on our deferred tax assets because we believe it is more likely than not that the deferred tax assets will not be realized. At December 31, 2017, we had federal and state net operating loss carryforwards of $1.7 billion and $1.5 billion, respectively, which will expire, if unused, beginning in 2022 and 2018, respectively.
Net Income (Loss) Attributable to Noncontrolling Interests
We determine the net income (loss) attributable to common stockholders by deducting from net income (loss) in a period the net income (loss) attributable to noncontrolling interests. We allocate profits and losses to the noncontrolling interests under the hypothetical liquidation at book value (HLBV) method. HLBV is a balance sheet-oriented approach for applying the equity method of accounting when there is a complex structure, such as our Investment Company structure.

Total Revenue
Total revenue increased approximately $82.1$31.3 million, or 94.6%18.5%, for the three months ended March 31, June 30, 20182019, as compared to the three months ended June 30, 2017. There were four principal driversMarch 31, 2018. Revenue in the three months ended March 31, 2018 included a one-time benefit of $45.5 million associated with the 2017 retroactive ITC benefit recognized in the same period in 2018. Excluding this one-time retroactive ITC benefit in 2018, revenue increase.
First,increased during the three months ended March 31, 2019 by approximately $76.8 million, or 62.0% compared to the same period in 2018. This increase was driven primarily by the increase in product acceptances increased byof approximately 1969 systems, or 11.7%41.6%, for the three months ended March 31, June 30, 20182019, as compared to the three months ended June 30, 2017.March 31, 2018.
Second, we achieved a significantly higher mix of orders to customers where revenue is recognized on acceptance, compared to revenue from the Bloom Electrons and managed services financing programs where revenue is recognized over the term of the agreement. In the three months ended June 30, 2018, we recognized 100.0% of our orders at acceptance, whereas only 69.0% of total acceptances in the three months ended June 30, 2017 were recognized at acceptance.
Third, the ITC was reinstated on February 9, 2018. ITC was not available to the fuel cell industry in 2017, however our revenue in 2018 includes the benefit of the reinstatement. The total revenue for the three months ended June 30, 2018 included $28.8 million of benefit from ITC, whereas the total revenue for the three months ended June 30, 2017 included $2.4 million of benefit, thus an increase in benefit from ITC to revenue of $26.4 million compared to the same period in 2017.
Lastly, the adoption of customer personalized applications such as batteries and grid-independent solutions increased in the three months ended June 30, 2018 compared to the three months ended June 30, 2017. Products that incorporate these personalized applications have, on average, higher revenue than our standard platform products that do not incorporate these personalized applications.
Product Revenue
Product revenue increased approximately $68.7 million, or 172.1%, for the three months ended June 30, 2018, compared to the three months ended June 30, 2017. This increase was driven by the factors impacting total revenue as mentioned above.
Installation Revenue
Installation revenue increased approximately $11.9 million, or 82.8%, from $14.4 million for the three months ended June 30, 2017 to $26.2 million for the three months ended June 30, 2018. This increase was driven by the factors impacting total revenue as mentioned above.
Product and Installation Revenue Combined
Product and installation revenue combined increased approximately $80.6$28.6 million, or 148.5%21.1%, to $134.9$164.0 million for the three months ended March 31, June 30, 20182019 from $54.3$135.4 million for the three months ended June 30, 2017. Depending on the customer purchase option elected by our customers, the product, installation and electricity revenue for that contract will either be recognized up front at acceptance or ratably over the life of the contract. The ratable portion of the product and install revenue increased approximately $0.6 million, to $6.9 million for the three months ended June 30, 2018 from $6.3 million for the three months ended June 30, 2017. This increase was primarily due to the increase in ratable acceptances through 2017.
March 31, 2018. The upfront portion of the product and install revenue increased approximately $80.0$32.9 million to $128.0$161.4 million for the three months ended June 30, 2018March 31, 2019 from $48.0$128.6 million for the three months ended June 30, 2017.March 31, 2018. This increase in upfront product and install revenue was

primarily due to the increase in upfront acceptances to 181235 in the three months ended June 30, 2018March 31, 2019 from 111166 in the three months ended June 30, 2017.March 31, 2018. The upfront product and install average selling price increaseddecreased to

$7,093 $6,870 per kilowatt for the three months ended June 30, 2018,March 31, 2019, from $4,317$7,745 per kilowatt for the three months ended June 30, 2017March 31, 2018, primarily driven by higherthe one-time 2017 retroactive ITC benefit recognized in the same period in 2018.
Product Revenue
Product revenue increased approximately $20.4 million, or 16.8%, for the three months ended March 31, 2019, as compared to the three months ended March 31, 2018. This increase was primarily driven by the increase in acceptances of 69 systems, partially offset by a one-time benefit associated with the 2017 retroactive ITC benefit recognized in the same period in 2018.
Installation Revenue
Installation revenue increased approximately $8.1 million, or 57.7%, from $14.1 million for the three months ended March 31, 2018 to $22.3 million for the three months ended March 31, 2019. This increase was generally driven by the increase in acceptances for the three months ended March 31, 2019 compared to the three months ended March 31, 2018. In addition to the change in acceptance volume, installation revenue can increase or decrease from period to period as a result of differences in size and complexity for the increased salesites accepted. Both the cost and revenue of installations can vary based on the size of the installation, the complexity of the installation, the features and ancillary equipment included in the installation, and whether or not we perform the installation as part of the overall scope of the customer personalized applications.contract.
Service Revenue
Service revenue increased approximately $1.1$3.4 million, or 5.8%17.0%, for the three months ended March 31, June 30, 20182019, as compared to the three months ended June 30, 2017.March 31, 2018. This was primarily due to the increase in the number of annual maintenance contract renewals driven by our increase in total megawatts deployed.growing fleet of installed Energy Servers.
Electricity Revenue
Electricity revenue increaseddecreased approximately $0.4$0.6 million, or 2.8%4.3%, for the three months ended March 31, June 30, 20182019, as compared to the three months ended June 30, 2017March 31, 2018, due to the normal fluctuationsfluctuation in system performance.energy produced by the PPA entities' Energy Servers.

This increase was primarily driven by the increase in installation costs resulting from the saledifference in size and complexity for the sites accepted in the three months ended March 31, 2019.
Cost of customer personalized applications which haveProduct Revenue
Cost of product revenue increased approximately $43.6 million, or 54.3%, for the three months ended March 31, 2019, as compared to the three months ended March 31, 2018. This increase was driven by the increase in acceptances and an increase in stock-based compensation, partially offset by a higher per unit cost.one-time payment of $9.4 million recorded to cost of product revenue in the three months ended March 31, 2018. This $9.4 million cost was driven by the reinstatement of the ITC program in February 2018, where we were required to repay certain suppliers for previously negotiated contractual discounts.
Cost of Installation Revenue
Cost of installation revenue increased approximately $13.7 million, or 131.5%, for the three months ended March 31, 2019, as compared to the three months ended March 31, 2018. This increase was generally driven by the increase in acceptances, as well as the difference in size and complexity for the sites accepted in the three months ended March 31, 2019.

Total Revenue
Total revenue increased approximately $179.3 million, or 112.8%, for the six months ended June 30, 2018, compared to the six months ended June 30, 2017. There were four principal drivers of this revenue increase.
First, product acceptances increased by approximately 66 systems, or 23.5%, for the six months ended June 30, 2018, compared to the three months ended June 30, 2017.
Second, we achieved a significantly higher mix of orders through direct sales to customers where revenue is recognized on acceptance, compared to revenue from the Bloom Electrons and managed services financing programs where revenue is recognized over the term of the agreement. In the six months ended June 30, 2018, we recognized 100.0% of our orders at acceptance, whereas only 63.0% of total acceptances in the six months ended June 30, 2017 were recognized at acceptance.
Third, the ITC was reinstated on February 9, 2018. ITC was not available to the fuel cell industry in 2017, however our revenue in 2018 includes the benefit of the reinstatement. The total revenue for the six months ended June 30, 2018 included $91.2 million of benefit from ITC, whereas the total revenue for the six months ended June 30, 2017 included $4.8 million of benefit, thus an increase in benefit to revenue from ITC of $86.4 million compared to the same period in 2017. The $91.2 million benefit of ITC in the six months ended June 30, 2018 included $45.5 million benefit of the retroactive ITC for 2017 acceptances.
Lastly, the adoption of customer personalized applications such as batteries and grid-independent solutions increased in the six months ended June 30, 2018 compared to the six months ended June 30, 2017. Products that incorporate these personalized applications have, on average, higher revenue than our standard platform products that do not incorporate these personalized applications.
Product Revenue
Product revenue increased approximately $162.4 million, or 240.2%, for the six months ended June 30, 2018, compared to the six months ended June 30, 2017. This increase was driven by the factors impacting total revenue as mentioned above.
Installation Revenue
Install revenue increased approximately $13.7 million, or 51.5%, from $26.6 million for the six months ended June 30, 2017 to $40.4 million for the six months ended June 30, 2018. This increase was driven by the factors impacting total revenue as mentioned above, partially offset by the lower installation revenue associated with one large customer in the six months

ended June 30, 2018 where the installation was performed by the customer, therefore, we did not have any installation revenue for that customer.
Service Revenue
Service revenue increased approximately $2.4 million, or 6.4% for the six months ended June 30, 2018, compared to the six months ended June 30, 2017. This was primarily due to the increase in the number of annual maintenance contract renewals driven by the increase in total megawatts deployed.
Electricity Revenue
Electricity revenue increased approximately $0.8 million, or 2.8%, for the six months ended June 30, 2018, compared to the six months ended June 30, 2017, due to normal fluctuations in system performance.

Total Cost of Revenue
Total cost of revenue increased approximately $87.8 million, or 50.5%, for the six months ended June 30, 2018, compared to the six months ended June 30, 2017. This increase in cost of revenue was primarily attributable to higher product and install cost of revenue which was driven by an increase in the product acceptances and a higher mix of orders to customers in which cost of revenue is recognized on acceptance. Additionally there was an increase in the sale of customer personalized applications for the six months ended June 30, 2018, and thus an increase in cost of revenue.
Cost of Product Revenue
Cost of product revenue increased approximately $64.8 million, or 75.0%, for the six months ended June 30, 2018, compared to the six months ended June 30, 2017.This increase was driven by the factors impacting total cost of revenue as mentioned above. Additionally, a one-time impact of $9.4 million was included in the cost of product revenue for the six months ended June 30, 2018 which was associated with supplier agreements that required us to forego previously negotiated discounts if ITC was renewed.
Cost of Installation Revenue
Cost of installation revenue increased approximately $19.2 million, or 68.0%, for the six months ended June 30, 2018, compared to the six months ended June 30, 2017.This increase was driven by the factors impacting total cost of revenue as mentioned above, partially offset by the lower cost of install associated with one large customer in the six months ended June 30, 2018 where the installation was performed by the customer, therefore, we did not have any installation cost for that customer.
Cost of Service Revenue
Cost of service revenue increased approximately $4.0 million, or 10.1%, for the six months ended June 30, 2018, compared to the six months ended June 30, 2017.This increase was primarily due to a higher number of power module replacements driven by the maintenance cycle of our Energy Servers.
Cost of Electricity Revenue
Cost of electricity revenue decreased approximately $0.2 million, or 0.8%, for the six months ended June 30, 2018, compared to the six months ended June 30, 2017.

Installation Gross Profit
Installation gross profit decreased $5.5 million in the six months ended June 30, 2018, compared to the six months ended June 30, 2017. This reduction in profit was due to higher install cost from the initial installations with the new customer personalized applications.

Liquidity and Capital Resources
As of June 30, 2018,March 31, 2019, we had an accumulated deficit of approximately $2.4$2.7 billion. We financehave financed our operations, including the costs of acquisition and installation of Energy Servers, mainly through a variety of financing arrangements and PPA Entities, credit facilities from banks, sales of our preferred and common stock, debt financings and cash generatedprovided from our operations. As of June 30, 2018,March 31, 2019, we had $1.0 billion$401.3 million of total outstanding recourse debt and $397.8 million of total outstanding non-recourse debt plus other long term liabilities. See Note 6 - Outstanding Loans and Security Agreements for a complete description of our outstanding debt. As of June 30, 2018March 31, 2019 and December 31, 2017,2018, we had cash and cash equivalents and short-term investments of $107.3$320.4 million and $130.6$325.1 million, respectively.
We believe that our existing cash and cash equivalents and short-term investments will be sufficient to meet our operating cash flow, capital requirements and other cash flow needs for at least the next 12 months. Our future capital requirements may vary materially from those currently planned and will depend on many factors, including our rate of revenue growth, the timing and extent of spending on research and development efforts and other business initiatives, the rate of growth in the volume of system builds, the expansion of sales and marketing activities, market acceptance of our products, the timing of receipt by us of distributions from our PPA Entities and overall economic conditions. We do not expect to receive significant cash distributions from our PPA Entities. To the extent that current and anticipated future sources of liquidity are insufficient to fund our future business activities and requirements, we may be required to seek additional debt or equity financing.
In July 2018, and subsequent to the date of the financial statements included in this Quarterly Report on Form 10-Q, we successfully completed an initial public stock offeringIPO with the sale of 20,700,000 shares of our Class A common stock at a price of $15.00 per share, resulting in cash proceeds of $284.3$282.3 million, net of underwriting discounts, commissions and estimated offering costs. We intend to use the net proceeds from this offering for general corporate purposes including research and development and sales and marketing activities, general and administrative matters and capital expenditures.

Operating Activities
In the sixthree months ended June 30, 2018,March 31, 2019, we used approximately $18.6$4.2 million of cash in operating activities. This use of cash resulted primarily from a net operating loss of $63.4$88.3 million, which included net non-cash charges of $73.5 million and a non-cash loss attributable to non-controlling interests of $9.1$79.9 million. Non-cash items include depreciation and amortization of approximately $21.6$11.3 million, a gain on revaluation of derivative contracts of $28.6$0.5 million, stock-based compensation of $15.8$63.9 million and amortization of debt discount of $12.0 million, partially offset by a revaluation of preferred stock warrants of $7.5$3.9 million. CashNet cash used in operating activities consisted primarily of an increase in inventory of $46.2 million, and increase in accounts receivable of $6.5 million, a decrease in deferred revenue and customer deposits of approximately $31.8$44.5 million relating to upfront milestone payments received from customers, an increasea decrease in accounts payable of $2.5 million, and a decrease in accrued warranty of $2.5 million, mostly offset by a decrease in inventory of $15.9 million, a decrease in accounts receivable of $0.8 million, a decrease in prepaid expenses and other current liabilitiesassets of $12.8$5.2 million, partially offset by a decrease in deferred cost of revenue of $48.8$26.0 million, an increase in other current liabilities of $0.8 million and an increase in other long-term liabilities of $18.7$3.5 million.
In the sixthree months ended June 30, 2017,March 31, 2018, we used approximately $79.6$34.5 million in operating activities. This use of cash resulted primarily from a net operating loss of $123.0$22.3 million, which included net non-cash charges of $59.8$33.2 million and apartially offset by non-cash loss attributable to non-controlling interestsbenefits of $10.0$3.4 million. Non-cash items include depreciation and amortization of approximately $23.6$10.8 million, a loss on revaluation of derivative contracts of $7.2 million, stock-based compensation of $14.7$8.0 million and amortization of debt discount of $20.6$5.9 million. CashNet cash used in operating activities consisted primarily of an increase in inventoryaccounts receivable of $17.6$28.2 million, an increase in inventory of $6.8 million, an increase in prepaid expenses and other current assets of $0.4 million, a decrease in accounts receivablepayable of $5.3$0.8 million, a decrease of accrued other current liabilities of $10.1 million, and a decrease in deferred revenue and customer deposits of $22.3 million relating to upfront milestone payments received from customers, partially offset by a decrease in deferred cost of revenue of $16.3 million, and an increase in other long term liabilities of $8.0 million.
Net cash used in operating activities decreased $30.3 million for the three months ended March 31, 2019 when compared to the prior year's three months ended March 31, 2018. This decrease was primarily the result of other activities providing cash flow source improvements including an increase in deferred cost of revenue of $34.9$26.0 million compared to the prior year's period increase of $16.3 million, and a decrease in accounts payable of $13.3$2.5 million compared to a decrease of $0.8 million in the prior year's period, a decrease in inventory for 2019 of $15.9 million compared to the prior year's increase of $6.9 million, a decrease in accounts receivable of $0.8 million compared to the prior year's increase of $28.2 million. Activities which partially offset the decrease of cash used in operating activities were an increase in our net loss of $65.9 million only partially offset by an increase in other long term liabilitiesa higher net non-cash items benefit of $24.9$50.1 million and an increasewhen compared to the prior year's period, a decrease in deferred revenue and customer deposits of approximately $35.9$44.5 million relating to upfront milestone payments received from customers.
Net cash used in operating activities improved by $61.0 million for the six months ended June 30, 2018 when compared to the six months ended June 30, 2017. This increase was primarily the result of an improvement in our net loss of $59.6 million. The non-cash charges of depreciation and stock-based compensation were similar in both periods, as was the loss attributable to noncontrolling interests. We had an increase in the non-cash revaluation of derivative contracts of $29.9 million as a result of the changes in our stock price. Significant changes in cash used includes an increase in inventory of $28.6 million due to an increase in the production volume when compared to 2017's increase in inventory, a substantial increase in the payment of other current liabilities as compared to a decrease of payments$22.3 million of those accounts in the previousprior year's six months, and a significant decrease in deferred revenue and customer deposits compared to an increase in the six month period in 2017. Cash provided by operating activities was most affected byperiod.

this year's decrease in deferred revenue and customer deposits when compared to last year's increase, this year's accounts payable increase when compared to the six month period in 2017's decrease, both of which were partially offset by a lesser increase in long term liabilities for the six months ended June 30, 2018 when compared to the six months ended June 30, 2017.

Recourse debt refers to debt that Bloom Energy Corporation has an obligation to pay. Non-recourse debt refers to debt that is recourse to only specified assets or subsidiaries of the Company. The differences between the unpaid principal balances and the net carrying values are due to debt discounts and deferred financing costs. We were in compliance with all of our financial covenants as of March 31, 2019 and 2018.

Recourse Debt Facilities
LIBOR + 4% Term Loan due November 2020 - In May 2013, we entered into a $5.0 million credit agreement and a $12.0 million financing agreement to help fund the building of a new facility in Newark, Delaware. The $5.0 million credit agreement expired in December 2016. The $12.0 million financing agreement has a term of 90 months, payable monthly at a variable rate equal to one-month LIBOR plus the applicable margin. The weighted average interest rate as of March 31, 2019 and 2018 was 6.5% and 5.9%, respectively. The loan requires monthly payments and is secured by the manufacturing facility. In addition, the credit agreements also include a cross-default provision which provides that the remaining balance of borrowings under the agreements will be due and payable immediately if a lien is placed on the Newark facility in the event we default on any indebtedness in excess of $100,000 individually or $300,000 in the aggregate. Under the terms of these credit agreements, we are required to comply with various restrictive covenants. As of March 31, 2019 and 2018, the debt outstanding was $2.9 million and $3.3 million, respectively.
5% Convertible Promissory Notes due 2020 (Originally 8% Convertible Promissory Notes due December 2018) - Between December 2014 and June 2016, we issued $193.2 million of three-year convertible promissory notes ("8% Notes") to certain investors. The 8% Notes had a fixed interest rate of 8% compounded monthly, due at maturity or at the election of the investor with accrued interest due in December of each year.
On January 18, 2018, amendments were finalized to extend the maturity dates for all the 8% Notes to December 2019. At the same time, the portion of the notes that was held by Constellation NewEnergy, Inc. ("Constellation") was extended to December 2020 and the interest rate decreased from 8% to 5% ("5% Notes").
Investors held the right to convert the unpaid principal and accrued interest of both the 8% and 5% notes to Series G convertible preferred stock at any time at the price of $38.64. In July 2018, upon our IPO, the $221.6 million of principal and accrued interest of outstanding 8% Notes automatically converted into additional paid-in capital, the conversion of which included all the related-party noteholders. The 8% Notes converted to shares of Series G convertible preferred stock and, concurrently, each such share of Series G convertible preferred stock converted automatically into one share of Class B common stock. Upon the Company's IPO, 5,734,440 shares of Class B common stock were issued from conversions and the 8% Notes were retired. Constellation, the holders of the 5% convertible promissory notes, have not elected to convert as of March 31, 2019. The outstanding unpaid principal and accrued interest debt balance of the 5% Note of $34.7 million was classified as non-current as of March 31, 2019, and the outstanding unpaid principal and accrued interest debt balance of the 8% Notes of $244.7 million was classified as non-current as of December 31, 2018.
6% Convertible Promissory Notes due December 2020 - Between December 2015 and September 2016, we issued $260.0 million convertible promissory notes due December 2020 ("6% Notes") to certain investors. The 6% Notes bore a 5% fixed interest rate, payable monthly either in cash or in kind, at our election. We amended the terms of the 6% Notes in June 2017 to reduce the collateral securing the notes and to increase the interest rate from 5% to 6%.
As of March 31, 2019 and 2018, the amount outstanding on the 6% Notes, which includes interest paid in kind through the IPO date, was $296.2 million and $286.1 million, respectively. Upon the IPO, the debt is convertible at the option of the holders at the conversion price of $11.25 per share into common stock at any time through the maturity date. In January 2018, we amended the terms of the 6% Notes to extend the convertible put option, which investors could elect only if the IPO did not occur prior to December 2019. After the IPO, we paid the interest in cash when due and no additional interest accrued on the consolidated balance sheet on the 6% Notes.
On or after July 27, 2020, we may redeem, at our option, all or part of the 6% Notes if the last reported sale price of our common stock has been at least $22.50 for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending within the three trading days immediately preceding the date on which we provide written notice of redemption. In certain circumstances, the 6% Notes are also redeemable at our option in connection with a change of control.
Under the terms of the indenture governing the 6% Notes, we are required to comply with various restrictive covenants, including meeting reporting requirements, such as the preparation and delivery of audited consolidated financial statements, and restrictions on investments. In addition, we are required to maintain collateral which secures the 6% Notes in an amount equal to 200% of the principal amount of and accrued and unpaid interest on the outstanding notes. This minimum collateral test is not a negative covenant and does not result in a default if not met. However, the minimum collateral test does restrict us with respect to investing in non-PPA subsidiaries. If we do not meet the minimum collateral test, we cannot invest cash into any non-PPA subsidiary that is not a guarantor of the notes. The 6% Notes also include a cross-acceleration provision which provides that the holders of at least 25% of the outstanding principal amount of the 6% Notes may cause such notes to become immediately due and payable if we or

any of our subsidiaries default on any indebtedness in excess of $15.0 million such that the repayment of such indebtedness is accelerated.
In connection with the issuance of the 6% Notes, we agreed to issue to J.P. Morgan and CPPIB, upon the occurrence of certain conditions, warrants to purchase we common stock up to a maximum of 146,666 shares and 166,222 shares, respectively. On August 31, 2017, primarilyJ.P. Morgan transferred its rights to CPPIB. Upon completion of the resultIPO, the 312,888 warrants were net exercised for 312,575 shares of Class B Common stock.
10% Notes due July 2024 - In June 2017, we issued $100.0 million borrowedof senior secured notes ("10% Notes"). The 10% Notes mature between 2019 and 2024 and bear a 10.0% fixed rate of interest, payable semi-annually. The 10% Notes have a continuing security interest in the cash flows payable to us as servicing, operations and maintenance fees and administrative fees from the five active power purchase agreements in our Bloom Electrons program. Under the terms of the indenture governing the notes, we are required to comply with various restrictive covenants including, among other things, to maintain certain financial ratios such as debt service coverage ratios, to incur additional debt, issue guarantees, incur liens, make loans or investments, make asset dispositions, issue or sell share capital of our subsidiaries and pay dividends, meet reporting requirements, including the preparation and delivery of audited consolidated financial statements, or maintain certain restrictions on investments and requirements in incurring new debt. As of March 31, 2019, we were in compliance with all of such covenants. In addition, we are required to maintain collateral which secures the 10% Notes based on debt ratio analyses. This minimum collateral test is not a negative covenant and does not result in a default if not met. However, the minimum collateral test does restrict us with respect to investing in non-PPA subsidiaries. If we do not meet the minimum collateral test, we cannot invest cash into any non-PPA subsidiary that is not a guarantor of the notes.

ITEM 3 - QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
We are exposedThere were no significant changes to our quantitative and qualitative disclosures about market risk during the first three months of fiscal 2019. Please refer to Part II, Item 7A. Quantitative and Qualitative Disclosures about Market Risk included in our Annual Report on Form 10-K for our fiscal year ended December 31, 2018 for a more complete discussion of the market risks as part of our ongoing business operations, primarily by exposure to changes in interest rates, in commodity fuel prices and in foreign currency.
Interest Rates
Our cash and cash equivalents are invested in money market funds and our short-term investments are invested in U.S. Treasury bills. Due to the short-term nature of our cash equivalents and short-term investments, we believe that we do not have any material revenue exposure to changes in fair value as a result of changes in interest rates. Additionally, given the low levels of interest earned on money market funds and U.S. Treasury bills, any exposure to market rate interest fluctuations would not have a material effect on our operating results or financial condition.
We are exposed to interest rate risk related to our indebtedness that bears interest based on a floating LIBOR rate. We generally hedge such interest rate risks with the use of hedging instruments. Changes in interest rates which may affect our indebtedness are generally offset by interest rate swaps. For our fixed-rate debt, interest rate changes do not affect our earnings or cash flows. We do not believe that an increase or decrease in interest rates by a hypothetical 10% would have a material effect on our operating results or financial condition.encounter.

Commodity Price Risk
We are subject to commodity price risk arising from price movements for natural gas that we supply to customers to operate our Energy Servers under certain power purchase agreements. We manage this risk by entering into forward commodity contracts associated with the cost of natural gas as economic hedges. As a result, we do not believe that a hypothetical 10% change in commodity prices would have a material effect on our operating results or financial condition.
Foreign Currency Risk
Our sales contracts are primarily denominated in U.S. dollars and, therefore, substantially all of our revenue is not subject to foreign currency market risk. As a result, we do not believe that a hypothetical 10% change in foreign currency exchange rates would have a material effect on our operating results or financial condition.
However, an increasing portion of our operating expenses is incurred outside the United States, is denominated in foreign currencies and is subject to such risk. Although not yet material, if we are not able to successfully hedge against the risks associated with currency fluctuations in our future activities, our financial condition and operating results could be adversely affected.
ITEM 4 - CONTROLS AND PROCEDURES
Evaluation of Disclosure Controls and Procedures
We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in
our reports made as defined in Rules 13-a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (Exchange Act), is
recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and that such
information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial
Officer as appropriate, to allow for timely decisions regarding required disclosure.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934), as amended (the Exchange Act), as of June 30, 2018.March 31, 2019. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that as of June 30, 2018March 31, 2019, controls and procedures were effective to provide reasonable assurance that information required to be disclosed in the reports we file and submit under the Exchange Act is recorded, processed, summarized and reported as and when required, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding its required disclosure.
Changes in Internal Control Over Financial Reporting
There were no changes in our internal control over financial reporting identified in management’s evaluation pursuant to Rules 13a-15(d) or 15d-15(d) of the Exchange Act during the period covered by this Quarterly Report on Form 10-Q that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
Inherent Limitation on Effectiveness of Controls and Procedures
Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent or detect all errors and all fraud. A controls system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the controls system are met. Further, the design of a controls system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all controls systems, no evaluation of controls can provide absolute assurance that all controls issues and instances of fraud, if any, within our company have been detected. Accordingly, our disclosure controls and procedures provide reasonable assurance of achieving their objectives.

ITEM 1 - LEGAL PROCEEDINGS
For a discussion of legal proceedings, see "Legal Matters" under Note 13 - Commitments and Contingencies, in the notes to our condensed consolidated financial statements. 
We are, and from time to time we may become, involved in legal proceedings or be subject to claims arising in the ordinary course of our business. We are not presently a party to any other legal proceedings that in the opinion of our

management and if determined adversely to us, would individually or taken together have a material adverse effect on our business, operating results, financial condition or cash flows.

ITEM 1A - RISK FACTORS
A description of the risks and uncertainties associated with our business is set forth below. You should carefully consider the risks and uncertainties described below, as well as the other information in this Quarterly Report on Form 10-Q, including our consolidated financial statements and the related notes and “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” The occurrence of any of the events or developments described below, or of additional risks and uncertainties not presently known to us or that we currently deem immaterial, could materially and adversely affect our business, financial condition, operating results and prospects. In such an event, the market price of our Class A common stock could decline and you could lose all or part of your investment.decline.

Risks Relating to Our Business, Industry and IndustrySales
The distributed generation industry is an emerging market and distributed generation may not receive widespread market acceptance.
The distributed generation industry is still relatively nascent in an otherwise mature and heavily regulated industry, and we cannot be sure that potential customers will accept distributed generation broadly, or our Energy Server products specifically. Enterprises may be unwilling to adopt our solution over traditional or competing power sources for any number of reasons including the perception that our technology is unproven, they lack confidence in our business model, the perceived unavailability of back-up service providers to operate and maintain the Energy Servers, and lack of awareness of our product or their perception of regulatory or political headwinds. Because this is an emerging industry, broad acceptance of our products and services is subject to a high level of uncertainty and risk. If the market develops more slowly than we anticipate, our business will be harmed.
Our limited operating history and our nascent industry make evaluating our business and future prospects difficult.
From our inception in 2001 through 2008,2009, we were focused principally on research and development activities relating to our Energy Server technology. We did not deploy our first Energy Server and did not recognize any revenue until 2008.2009. As a result, we have a limited history operating our business at its current scale, and therefore a limited history upon which you can base an investment decision.
Ourscale. Furthermore, our Energy Server is a new type of product in the nascent distributed energy industry. PredictingConsequently, predicting our future revenue and appropriately budgeting for our expenses is difficult, and we have limited insight into trends that may emerge and affect our business. If actual results differ from our estimates or if we adjust our estimates in future periods, our operating results and financial position could be materially and adversely affected. You should consider our prospects in light of the risks

The distributed generation industry is an emerging marketregular and distributed generation may not receive widespread market acceptance.
The distributed generation industry is still relatively nascent, and we cannot be sure that potential customers will accept distributed generation more broadly, or our Energy Server products more specifically. Enterprises may be unwilling to adopt our solution over traditional or competing power sources for any number of reasons including the perception that our technology is unproven, lack of confidence intimely basis, our business model, unavailabilitycould be harmed.
Our sales cycle is typically 12 to 18 months but can vary considerably. In order to make a sale, we must typically provide a significant level of back-up service providerseducation to operateprospective customers regarding the use and maintain the Energy Servers, and lack of awarenessbenefits of our product.

The period between initial discussions with a potential customer and the eventual sale of our products and services are subject toeven a high level of uncertainty and risk. If the market develops more slowly than we anticipate, our business will be harmed.
We have incurred significant losses in the past and we do not expect to be profitable for the foreseeable future.
Since our inception in 2001, we have incurred significant net losses and have used significant cash in our business. As of June 30, 2018, we had an accumulated deficit of $2.4 billion. We expect to continue to expand our operations, including by investing in manufacturing, sales and marketing, research and development, staffing systems and infrastructure to support our growth. We anticipate that we will incur net losses on a US GAAP basis for the foreseeable future. Our ability to achieve profitability in the future will dependsingle product typically depends on a number of factors, including:

Our operating expenses are based on anticipated sales levels, and many of our expenses are fixed. If we are unsuccessful in closing sales after expending significant resources or if we experience delays or cancellations, our business could be materially and adversely affected. Since we do not recognize revenue on the sales of our products until installation and acceptance, a small fluctuation in the timing of the completion of our sales transactions could cause operating results to vary materially from period to period.
Our Energy Servers have significant upfront costs, and we will need to attract investors to help customers finance purchases.
Our Energy Servers have significant upfront costs. In order to assist our customers in obtaining financing for our products, we have leasingtraditional lease programs with two leasing partners who have prequalified our product and provide financing for customers through various leasing arrangements. In addition to the leasingtraditional lease model, we also offer power purchase agreements (PPAs)Power Purchase Agreement Programs, including Third-Party PPAs, in which financing the cost of the Energy Server is provided by a subsidiary operating company ("an Operating Company")Company and funded by a subsidiary investment entity ("Investment(an "Investment Company", together the "PPA Entities") which is financed by us and/or

in combination with third-party investors ("Equity Investors").Investors. We refer to the Operating Company and its subsidiary Investment Company collectively as a PPA Entity. In recent periods, the substantial majority of our end customers have elected to finance their purchases, typically through PPA Entities.Third Party PPAs.
We will need to grow committed financing capacity with existing partners or attract additional partners to support our growth. Generally, at any point in time, the deployment of a portion of our backlog is contingent on securing available financing. Our ability to attract third-party financing depends on many factors that are outside of our control, including the investors’ ability to utilize tax credits and other government incentives, our perceived creditworthiness and the condition of credit markets generally. Our financing of customer purchases of our Energy Servers is subject to conditions such as the customer’s credit quality and the expected minimum internal rate of return on the customer engagement, and if these conditions are not satisfied, we may be unable to finance purchases of our Energy Servers, which would have an adverse effect on our revenue in a particular period. If we are unable to help our customers arrange financing for our Energy Servers generally, our business will be harmed. For example, we have been working with financing sources to arrange for additional third-party Power Purchase Agreement Program entities,Third-Party PPA Entities, one of which will need to be finalized in order for our customers to arrange financing so that we can complete our planned installations in the firstsecond quarter of 2019.
We do not currently have a committed financing partner willing to finance deployments with poor credit-quality customers. If we are unable to procure financing partners willing to finance such deployments, our ability to grow our business maywould be negatively impacted.
The economic benefits of our Energy Servers to our customers depends on the cost of electricity available from alternative sources including local electric utility companies, which cost structure is subject to change.
We believe that a customer’s decision to purchase our Energy Servers is significantly influenced by the price, the price predictability of electricity generated by our Energy Servers in comparison to the retail price and the future price outlook of electricity from the local utility grid and other renewable energy sources. The economic benefit of our Energy Servers to our customers includes, among other things, the benefit of reducing such customer’s payments to the local utility company. The rates at which electricity is available from a customer’s local electric utility company is subject to change and any changes in such rates may affect the relative benefits of our Energy Servers. Even in markets where we are competitive today, rates for electricity could decrease and render our Energy Servers uncompetitive. Several factors could lead to a reduction in the price or future price outlook for grid electricity, including the impact of energy conservation initiatives that reduce electricity consumption, construction of additional power generation plants (including nuclear, coal or natural gas) and technological developments by others in the electric power industry which could result in electricity being available at costs lower than those that can be achieved from our Energy Servers. If the retail price of grid electricity does not increase over time at the rate that we or our customers expect, it could reduce demand for our Energy Servers and harm our business.
Further, the local electric utility may impose “departing load,” “standby,” or other charges on our customers in connection with their acquisition of our Energy Servers, the amounts of which are outside of our control and which may have a material impact on the economic benefit of our Energy Servers to our customers. Changes in the rates offered by local electric utilities and/or in the applicability or amounts of charges and other fees imposed by such utilities on customers acquiring our Energy Servers could adversely affect the demand for our Energy Servers.
In some states and countries, the current low cost of grid electricity, even together with available subsidies, does not render our product economically attractive. If we are unable to reduce our costs to a level at which our Energy Servers would be

competitive in such markets, or if we are unable to generate demand for our Energy Servers based on benefits other than electricity cost savings, our potential for growth may be limited.
Furthermore, an increase in the price of natural gas or curtailment of availability could make our Energy Servers less economically attractive to potential customers and reduce demand.
We rely on net metering arrangements that are subject to change.
Because our Energy Servers are designed to operate at a constant output twenty-four hours a day, seven days a week and our customers’ demand for electricity typically fluctuates over the course of the day or week, there are often periods when our Energy Servers are producing more electricity than a customer may require, and such excess electricity must be exported to the local electric utility. Many, but not all, local electric utilities provide compensation to our customers for such electricity under “net metering” programs. Utility tariffs, interconnection agreements and net metering requirements are subject to changes in availability and terms. At times in the past, such changes have had the effect of significantly reducing or eliminating the benefits of such programs. Changes in the availability of, or benefits offered by, utility tariffs, the net metering requirements or interconnection agreements in place in the jurisdictions in which we operate could adversely affect the demand for our Energy Servers.
We currently face and will continue to face significant competition.
We compete for customers, financing partners, and incentive dollars with other electric power providers. Many providers of electricity, such as traditional utilities and other companies offering distributed generation products, have longer operating histories, have customer incumbency advantages, have access to and influence with local and state governments, and have access to more capital resources than do we. Significant developments in alternative technologies, such as energy storage, wind, solar, or hydro power generation, or improvements in the efficiency or cost of traditional energy sources, including coal, oil, natural gas used in combustion, or nuclear power, may materially and adversely affect our business and prospects in ways we cannot anticipate. We may also face new competitors who are not currently in the market. If we fail to adapt to changing market conditions and to compete successfully with grid electricity or new competitors, our growth will be limited which would adversely affect our business results.
We derive a substantial portion of our revenue and backlog from a limited number of customers, and the loss of or a significant reduction in orders from a large customer could have a material adverse effect on our operating results and other key metrics.
In any particular period, a substantial amount of our total revenue could come from a relatively small number of customers. As an example, in the three months ended March 31, 2019, three customers accounted for approximately 72% of our total revenue. In year ended December 31, 2018, two customers accounted for approximately 54% of our total revenue. One of these customers, the Southern Company, wholly owns a Third-Party PPA, and this entity purchases Energy Servers, that are then provided to various end customers under PPAs. The loss of any large customer order or any delays in installations of new Energy Servers with any large customer could materially and adversely affect our business results.
Risks Relating to Our Products and Manufacturing
Our future success depends in part on our ability to increase our production capacity, and we may not be able to do so in a cost-effective manner.
To the extent we are successful in growing our business, we may need to increase our production capacity. Our ability to plan, construct, and equip additional manufacturing facilities is subject to significant risks and uncertainties, including the following:
The expansion or construction of any manufacturing facilities will be subject to the risks inherent in the development and construction of new facilities, including risks of delays and cost overruns as a result of factors outside our control such as delays in government approvals, burdensome permitting conditions, and delays in the delivery of manufacturing equipment and subsystems that we manufacture or obtain from suppliers.
It may be difficult to expand our business internationally without additional manufacturing facilities located outside the United States. Adding manufacturing capacity in any international location will subject us to new laws and regulations including those pertaining to labor and employment, environmental and export import. In addition, it brings with it the risk of managing larger scale foreign operations.
We may be unable to achieve the production throughput necessary to achieve our target annualized production run rate at our current and future manufacturing facilities.

Manufacturing equipment may take longer and cost more to engineer and build than expected, and may not operate as required to meet our production plans.
We may depend on third-party relationships in the development and operation of additional production capacity, which may subject us to the risk that such third parties do not fulfill their obligations to us under our arrangements with them.
We may be unable to attract or retain qualified personnel.
If we are unable to expand our manufacturing facilities, we may be unable to further scale our business. If the demand for our Energy Servers or our production output decreases or does not rise as expected, we may not be able to spread a significant amount of our fixed costs over the production volume, resulting in a greater than expected per unit fixed cost, which would have a negative impact on our financial condition and our results of operations.
If we are not able to continue to reduce our cost structure in the future, our ability to become profitable may be impaired.
We must continue to reduce the manufacturing costs for our Energy Servers to expand our market. Additionally, certain of our existing service contracts were entered into based on projections regarding service costs reductions that assume continued advances in our manufacturing and services processes which we may be unable to realize. While we have been successful in reducing our manufacturing and services costs to date, the cost of components and raw materials, for example, could increase in the future. Any such increases could slow our growth and cause our financial results and operational metrics to suffer. In addition, we may face increases in our other expenses including increases in wages or other labor costs as well as installation, marketing, sales or related costs. We may continue to make significant investments to drive growth in the future. In order to expand into new electricity markets (in which the price of electricity from the grid is lower) while still maintaining our current margins, we will need to continue to reduce our costs. Increases in any of these costs or our failure to achieve projected cost reductions could adversely affect our results of operations and financial condition and harm our business and prospects. If we are unable to reduce our cost structure in the future, we may not be able to achieve profitability, which could have a material adverse effect on our business and our prospects.
If our Energy Servers contain manufacturing defects, our business and financial results could be harmed.
Our Energy Servers are complex products and they may contain undetected or latent errors or defects. In the past, we have experienced latent defects only discovered once the Energy Server is deployed in the field. Changes in our supply chain or the failure of our suppliers to otherwise provide us with components or materials that meet our specifications could also introduce defects into our products. In addition, as we grow our manufacturing volume, the chance of manufacturing defects could increase. Any manufacturing defects or other failures of our Energy Servers to perform as expected could cause us to incur significant re-engineering costs, divert the attention of our engineering personnel from product development efforts, and significantly and adversely affect customer satisfaction, market acceptance, and our business reputation.
Furthermore, we may be unable to correct manufacturing defects or other failures of our Energy Servers in a manner satisfactory to our customers, which could adversely affect customer satisfaction, market acceptance, and our business reputation.
The performance of our Energy Servers may be affected by factors outside of our control, which could result in harm to our business and financial results.
Field conditions, such as the quality of the natural gas supply and utility processes which vary by region and may be subject to seasonal fluctuations, have affected the performance of our Energy Servers and are not always possible to predict until the Energy Server is in operation. Although we believe we have designed new generations of Energy Servers to better withstand the variety of field conditions we have encountered, as we move into new geographies and deploy new service configurations, we may encounter new and unanticipated field conditions. Adverse impacts on performance may require us to incur significant re-engineering costs or divert the attention of our engineering personnel from product development efforts and significantly and adversely affect customer satisfaction, market acceptance and our business reputation.efforts. Furthermore, we may be unable to adequately address the impacts of factors outside of our control in a manner satisfactory to our customers, whichcustomers. Any of these circumstances could significantly and adversely affect customer satisfaction, market acceptance, and our business reputation.
If our estimates of useful life for our Energy Servers are inaccurate or we do not meet service and performance warranties and guarantees,guaranties, or if we fail to accrue adequate warranty and guaranty reserves, our business and financial results could be harmed.
We offer certain customers the opportunity to renew their operations and maintenance service agreements on an annual basis, for up to 2025 years, at prices predetermined at the time of purchase of the Energy Server. We also provide performance warranties and guaranties covering the efficiency and output performance of our Energy Servers. Our pricing of these contracts

and our reserves for warranty and replacement are based upon our estimates of the life of our Energy Servers and their components, including assumptions regarding improvements in useful life that may fail to materialize. We also provide performance warranties and guarantees covering the efficiency and output performance of our Energy Servers. We do not have a long history with a large number of field deployments, and our estimates may prove to be incorrect. Failure to meet these performance warranties and guaranteeguaranty levels may require us to replace the Energy Servers at our expense or refund their cost to the customer, or require us to make cash payments to the customer based on actual performance, as compared to expected performance, capped at a percentage of the relevant equipment purchase prices. We accrue for product warranty costs and recognize losses on service or performance warranties when required by U.S. GAAP based on our estimates of costs that may be incurred and based on historical experience. However, as we expect our customers to renew their maintenance service agreements each year, the total liability over time may be more than the accrual. Actual warranty expenses have in the past been and may in the future be greater than we have assumed in our estimates, the accuracy of which may be hindered due to our limited history operating at our current scale.
Early generations of our Energy Server did not have the useful life and did not perform at an output and efficiency level that we expected. We implemented a fleet decommissioning program for our early generation Energy Servers in our PPA I program, which resulted in a significant adjustment to revenue in the quarter ended December 31, 2015, as we would otherwise have failed to meet efficiency and

output warranties. As of June 30, 2018,March 31, 2019, we had a total of 5857 megawatts in total deployed early generation servers, including our first and second generation servers, out of our total installed base of 328396 megawatts. We accrue for product warranty costs and recognize losses on service or performance warranties based on our estimates of costs that may be incurred and based on historical experience; however, actual warranty expenses have in the past been and may in the future be greater than we have assumed in our estimates, the accuracy of which may be hindered due to our limited operating history operating at our current scale. We accrue for extended warranty costs that we expect to incur under the maintenance service agreements that our customers renew for a term of typically one year. In addition, we expect that our deployed early generation Energy Servers may continue to perform at a lower output and efficiency level and, as a result, the maintenance costs may exceed the contracted prices that we expect to generate in respect of those servers if our customers continue to renew their maintenance service agreements in respect of those servers.
Our business currently depends on the availability of rebates, tax credits and other financial incentives. The reduction, modification or elimination of government economic incentives could cause our revenue to decline and harm our financial results.
The U.S. federal government and some state and local governments provide incentives to end users and purchasers of our Energy Servers in the form of rebates, tax credits and other financial incentives, such as system performance payments and payments for renewable energy credits associated with renewable energy generation. We rely on these governmental rebates, tax credits and other financial incentives to significantly lower the effective price of the Energy Servers to our customers in the United States, including by lowering the cost of capital to our customers, as our financing partners and PPA Equity Investors may take advantage of these financial incentives. However, these incentives may expire on a particular date, end when the allocated funding is exhausted or be reduced or terminated as a matter of regulatory or legislative policy. For example, the federal ITC benefit expired on December 31, 2016 and without the availability of the ITC benefit incentive, we lowered the price of our Energy Servers to ensure the economics to our customers remain the same as it was prior to losing the ITC benefit, adversely affecting our gross profit. While the ITC was reinstated by the U.S Congress on February 9, 2018 and made retroactive to January 1, 2017, it is possible in the future that this incentive could be repealed.
Our Energy Servers have qualified for tax exemptions, incentives, or other customer incentives in many states including the states of California, Connecticut, Massachusetts, New Jersey and New York. Some states have utility procurement programs and/or renewable portfolio standards for which our technology is eligible. Our Energy Servers are currently installed in eleven U.S. states, each of which may have its own enabling policy framework. There is no guarantee that these policies will continue to exist in their current form, or at all. Such state programs may face increased opposition on the U.S. federal, state and local levels in the future. Changes in federal or state programs could reduce demand for our Energy Servers, impair sales financing and adversely impact our business results.
For example, the California Self Generation Incentive Program (SGIP) is a program administered by the California Public Utilities Commission (CPUC) which provides incentives to investor-owned utility customers that install eligible distributed energy resources. In July 2016, the CPUC modified the SGIP to provide a smaller allocation of the incentives available to generating technologies such as our Energy Servers and a larger allocation to storage technologies. As modified, the SGIP will require all eligible power generation sources consuming natural gas to use a minimum of 10% biogas to receive SGIP funds beginning in 2017, with this minimum biogas requirement increasing to 25% in 2018, 50% in 2019 and 100% in 2020. In addition, the CPUC provided a further limitation on the available allocation of funds that any one participant may claim under the SGIP. The SGIP will expire on January 21, 2021 absent extension. Our billings for product accepted derived from customers benefiting from the SGIP represented approximately 5% and 12% of total billings for product accepted for the six months ended June 30, 2018 and the year ended December 2017, respectively.
We rely on tax equity financing arrangements to realize the benefits provided by investment tax credits and accelerated tax depreciation and, in the event these programs are terminated, our financial results could be harmed.
We expect that any Energy Server deployments through financed transactions (including our Bloom Electrons programs, our leasing programs, and any third-party Power Purchase Agreement Programs) will receive capital from financing parties who derive a significant portion of their economic returns through tax benefits (Equity Investor). Equity Investors are generally entitled to substantially all of the project’s tax benefits, such as those provided by the ITC and MACRS depreciation, until the Equity Investors achieve their respective agreed rates of return. The number of and available capital from potential Equity Investors is limited, we compete with other energy companies eligible for these tax benefits to access such investors, and the availability of capital from Equity Investors is subject to fluctuations based on factors outside of our control such as macroeconomic trends and changes in applicable taxation regimes. Concerns regarding our limited operating history and lack of profitability have made it difficult to attract investors in the past. Our ability to obtain additional financing in the future depends on the continued confidence of banks and other financing sources in our business model, the market for our Energy Servers and the continued availability of tax benefits applicable to our Energy Servers. In addition, conditions in financial and credit

markets generally may result in the contraction of available tax equity financing. If we are unable to enter into tax equity financing agreements with attractive pricing terms or at all, we may not be able to attract the capital needed to fund our financing programs or use the tax benefits provided by the ITC and MACRS depreciation, which could make it more difficult for customers to finance the purchase of our Energy Servers or require us to reduce the price at which we are able to sell our Energy Servers and therefore harm our business, our financial condition and our results of operations.
We derive a substantial portion of our revenue and backlog from a limited number of customers, and the loss of or a significant reduction in orders from a large customer could have a material adverse effect on our operating results and other key metrics.
In any particular period, a substantial amount of our total revenue could come from a relatively small number of customers. As an example, for the year ended December 31, 2016, two customers accounted for approximately 29% of our total revenue. In 2017, two customers accounted for approximately 53% of our total revenue. Since we recognize the product revenue for customer-financed purchases at the time that the Energy Server is accepted, the loss of any large customer order or any delays in installations of new Energy Servers with any large customer could materially and adversely affect our business results.
Our products involve a lengthy sales and installation cycle and, if we fail to close sales on a regular and timely basis, our business could be harmed.
Our sales cycle is typically 12 to 18 months but can vary considerably. In order to make a sale, we must typically provide a significant level of education to prospective customers regarding the use and benefits of our product and its technology. The period between initial discussions with a potential customer and the eventual sale of even a single product typically depends on a number of factors, including the potential customer’s budget and decision as to the type of financing it chooses to use as well as the arrangement of such financing. Prospective customers often undertake a significant evaluation process which may further extend the sales cycle. Once a customer makes a formal decision to purchase our product, the fulfillment of the sales order by us requires a substantial amount of time. Currently, we believe the time between the entry into a sales contract with a customer and the installation of our Energy Servers can range from nine to twelve months or more. This lengthy sales and installation cycle is subject to a number of significant risks over which we have little or no control. Because of both the long sales and installation cycles, we may expend significant resources without having certainty of generating a sale.
These lengthy sales and installation cycles increase the risk that our customers will fail to satisfy their payment obligations or will cancel orders before the completion of the transaction or delay the planned date for installation. Generally, a customer can cancel an order prior to installation and we may be unable to recover some or all of our costs in connection with design, permitting, installation and site preparations incurred prior to cancellation. Cancellation rates can be between 10% and 20% in any given period due to factors outside of our control including an inability to install an Energy Server at the customer’s chosen location because of permitting or other regulatory issues, unanticipated changes in the cost, the availability of alternative sources of electricity available to the customer or other reasons unique to each customer. Our operating expenses are based on anticipated sales levels, and many of our expenses are fixed. If we are unsuccessful in closing sales after expending significant resources or if we experience delays or cancellations, our business could be materially and adversely affected. Since we do not recognize revenue on the sales of our products until installation and acceptance, a small fluctuation in the timing of the completion of our sales transactions could cause operating results to vary materially from period to period.
We rely on net metering arrangements that are subject to change.
Because our Energy Servers are designed to operate at a constant output twenty-four hours a day, seven days a week and our customers’ demand for electricity typically fluctuates over the course of the day or week, there are often periods when our Energy Servers are producing more electricity than a customer may require, and such excess electricity must be exported to the local electric utility. Many, but not all, local electric utilities provide compensation to our customers for such electricity under “net metering” programs. Net metering programs are subject to changes in availability and terms. At times in the past, such changes have had the effect of significantly reducing or eliminating the benefits of such programs. Changes in the availability of, or benefits offered by, the net metering programs in place in the jurisdictions in which we operate could adversely affect the demand for our Energy Servers.
The economic benefits of our Energy Servers to our customers depends on the cost of electricity available from alternative sources including local electric utility companies, which cost structure is subject to change.
The economic benefit of our Energy Servers to our customers includes, among other things, the benefit of reducing such customer’s payments to the local utility company. The rates at which electricity is available from a customer’s local electric utility company is subject to change and any changes in such rates may affect the relative benefits of our Energy Servers. Further, the local electric utility may impose “departing load,” “standby” or other charges on our customers in connection with

their acquisition of our Energy Servers, the amounts of which are outside of our control and which may have a material impact on the economic benefit of our Energy Servers to our customers. Changes in the rates offered by local electric utilities and/or in the applicability or amounts of charges and other fees imposed by such utilities on customers acquiring our Energy Servers could adversely affect the demand for our Energy Servers.
Additionally, the electricity produced by our Energy Servers is currently not cost competitive in many geographic markets, and we may be unable to reduce our costs to a level at which our Energy Servers would be competitive in such markets. As such, unless the cost of electricity in these markets rises or we are able to generate demand for our Energy Servers based on benefits other than electricity cost savings, our potential for growth may be limited.
Our business is subject to risks associated with construction, utility interconnection, cost overruns and delays, including those related to obtaining government permits and other contingencies that may arise in the course of completing installations.
Because we generally do not recognize revenue on the sales of our Energy Servers until installation and acceptance, our financial results are dependent, to a large extent, on the timeliness of the installation of our Energy Servers. Furthermore, in some cases, the installation of our Energy Servers may be on a fixed price basis, which subjects us to the risk of cost overruns or other unforeseen expenses in the installation process.
Although we generally are not regulated as a utility, federal, state and local government statutes and regulations concerning electricity heavily influence the market for our product and services. These statutes and regulations often relate to electricity pricing, net metering, incentives, taxation and the rules surrounding the interconnection of customer-owned electricity generation for specific technologies. In the United States, governments frequently modify these statutes and regulations. Governments, often acting through state utility or public service commissions, change and adopt different requirements for utilities and rates for commercial customers on a regular basis. Changes, or in some cases a lack of change, in any of the laws, regulations, ordinances or other rules that apply to our installations and new technology could make it more costly for us or our customers to install and operate our Energy Servers on particular sites and, in turn, could negatively affect our ability to deliver cost savings to customers for the purchase of electricity.
The construction, installation, and operation of our Energy Servers at a particular site is also generally subject to oversight and regulation in accordance with national, state, and local laws and ordinances relating to building codes, safety, environmental protection, and related matters, and typically requiresrequire various local and other governmental approvals and permits, including environmental approvals and permits, that vary by jurisdiction. In some cases, these approvals and permits require periodic renewal. It is difficult and costly to track the requirements of every individual authority having jurisdiction over our installations, to design our Energy Servers to comply with these varying standards, and to obtain all applicable approvals and permits. We cannot predict whether or when all permits required for a given project will be granted or whether the conditions associated with the permits will be achievable. The denial of a permit or utility connection essential to a project or the imposition of impractical conditions would impair our ability to develop the project. In addition, we cannot predict whether the permitting process will be lengthened due to complexities and appeals. Delay in the review and permitting process for a project can impair or delay our and our customers’ abilities to develop that project or may increase the cost so substantially that the project is no longer attractive to us or our customers. Furthermore, unforeseen delays in the review and permitting process could delay the timing of the installation of our Energy Servers and could therefore adversely affect the timing of the recognition of revenue related to the installation, which could harm our operating results in a particular period.
In addition, the completion of many of our installations is dependent upon the availability of and timely connection to the natural gas grid and the local electric grid. In some jurisdictions, the local utility company(ies) or the municipality has denied our request for connection or has required us to reduce the size of certain projects. Any delays in our ability to connect with utilities, delays in the performance of installation-related services, or poor performance of installation-related services by our general contractors or sub-contractors will have a material adverse effect on our results and could cause operating results to vary materially from period to period.
Furthermore, we rely on the ability of our third party general contractors to install Energy Servers at our customers’ sites.sites and to meet our installation requirements. We currently work with a limited number of general contractors, which has impacted and may continue to impact our ability to make installations as planned. Our work with contractors or their sub-contractors may have the effect of us being required to comply with additional rules (including rules unique to our customers), working conditions, site remediation, and other union requirements, which can add costs and complexity to an installation project. The timeliness, thoroughness, and quality of the installation-related services performed by some of our general contractors and their sub-contractors in the past have not always met our expectations or standards and in the future may not meet our expectations and standards.

The failure of our suppliers to continue to deliver necessary raw materials or other components of our Energy Servers in a timely manner could prevent us from delivering our products within required time frames, and could cause installation delays, cancellations, penalty payments, and damage to our reputation.
We rely on a limited number of third-party suppliers for some of the raw materials and components for our Energy Servers, including certain rare earth materials and other materials that may be of limited supply. If our suppliers provide insufficient inventory at the level of quality required to meet customer demand or if our suppliers are unable or unwilling to provide us with the contracted quantities (as we have limited or in some case no alternatives for supply), our results of operations could be materially and negatively impacted. If we fail to develop or maintain our relationships with our suppliers, or if there is otherwise a shortage or lack of availability of any required raw materials or components, we may be unable to manufacture our Energy Servers or our Energy Servers may be available only at a higher cost or after a long delay. Such delays could prevent us from delivering our Energy Servers to our customers within required timeframestime frames and cause order cancellations. We have had to create our own supply chain for some of the components and materials utilized in our fuel cells. We have made significant expenditures in the past to develop our supply chain. In many cases, we entered into contractual relationships with suppliers to jointly develop the components we needed. These activities were time and capital intensive. Accordingly, the number of suppliers we have for some of our components and materials is limited and in some cases sole sourced. Some of our suppliers use proprietary processes to manufacture components. We may be unable to obtain comparable components from alternative suppliers without considerable delay, expense, or at all, as replacing these suppliers could require us either to make significant investments to bring the capability in housein-house or to invest in a new suppliersupply chain partner. Some of our suppliers are smaller, private companies, heavily dependent on us as a customer. If our suppliers face difficulties obtaining the credit or capital necessary to expand their operations when needed, they could be unable to supply necessary raw materials and components needed to support our planned sales and services operations, which would negatively impact our sales volumes and cash flows.
Moreover, we may experience unanticipated disruptions to operations or other difficulties with our supply chain or internalized supply processes due to exchange rate fluctuations, volatility in regional markets from where materials are obtained particularly(particularly China and Taiwan,Taiwan), changes in the general macroeconomic outlook, global trade disputes, political instability, expropriation or nationalization of property, civil strife, strikes, insurrections, acts of terrorism, acts of war, or natural disasters. The failure by us to obtain raw materials or components in a timely manner or to obtain raw materials or components that meet our quantity and cost requirements could impair our ability to manufacture our Energy Servers or increase their costs or service costs of our existing portfolio of Energy Servers under maintenance services agreements. If we cannot obtain substitute materials or components on a timely basis or on acceptable terms, we could be prevented from delivering our Energy Servers to our customers within required timeframes, which could result in sales and installation delays, cancellations, penalty payments, or damage to our reputation, any of which could have a material adverse effect on our business and results of operations. In addition, we rely on our suppliers to meet quality standards, and the failure of our suppliers to meet or exceed those quality standards could cause delays in the delivery of our products, cause unanticipated servicing costs, and cause damage to our reputation.
Our financial condition and results of operations and other key metrics are likely to fluctuate on a quarterly basis in future periods, which could cause our results for a particular period to fall below expectations, resulting in a severe decline in the price of our Class A common stock.
Our financial condition and results of operations and other key metrics have fluctuated significantly in the past and may continue to fluctuate in the future due to a variety of factors, many of which are beyond our control. For example, the amount of product revenue we recognize in a given period is materially dependent on the volume of installations of our Energy Servers in that period and the type of financing used by the customer.
In addition to the other risks described herein, the following factors could also cause our financial condition and results of operations to fluctuate on a quarterly basis:
the timing of installations, which may depend on many factors such as availability of inventory, product quality or performance issues, or local permitting requirements, utility requirements, environmental, health and safety requirements, weather and customer facility construction schedules;
size of particular installations and number of sites involved in any particular quarter;
the mix in the type of purchase or financing options used by customers in a period, and the rates of return required by financing parties in such period;
whether we are able to structure our sales agreements in a manner that would allow for the product and installation revenue to be recognized up front at acceptance;
delays or cancellations of Energy Server installations;
fluctuations in our service costs, particularly due to unaccrued costs of servicing and maintaining Energy Servers;
weaker than anticipated demand for our Energy Servers due to changes in government incentives and policies;
fluctuations in our research and development expense, including periodic increases associated with the pre-production qualification of additional tools as we expand our production capacity;

interruptions in our supply chain;
the length of the sales and installation cycle for a particular customer;
the timing and level of additional purchases by existing customers;
unanticipated expenses or installation delays associated with changes in governmental regulations, permitting requirements by local authorities at particular sites, utility requirements and environmental, health and safety requirements; and
disruptions in our sales, production, service or other business activities resulting from disagreements with our labor force or our inability to attract and retain qualified personnel.
Fluctuations in our operating results and cash flow could, among other things, give rise to short-term liquidity issues. In addition, our revenue, key operating metrics and other operating results in future quarters may fall short of the expectations of investors and financial analysts, which could have an adverse effect on the price of our Class A common stock.
We must maintain customer confidence in our liquidity and long-term business prospects in order to grow our business.
Currently, we are the only provider able to fully support and maintain our Energy Servers. If potential customers believe we do not have sufficient capital or liquidity to operate our business over the long-term or that we will be unable to maintain their Energy Servers and provide satisfactory support, customers may be less likely to purchase or lease our products, particularly in light of the significant financial commitment required. In addition, financing sources may be unwilling to provide financing on reasonable terms. Similarly, suppliers, financing partners and other third parties may be less likely to invest time and resources in developing business relationships with us if they have concerns about the success of our business.
Accordingly, in order to grow our business, we must maintain confidence in our liquidity and long-term business prospects among customers, suppliers, financing partners and other parties. This may be particularly complicated by factors such as:
our limited operating history at a large scale;
our lack of profitability;
unfamiliarity with or uncertainty about our Energy Servers and the overall perception of the distributed generation market;
prices for electricity or natural gas in particular markets;
competition from alternate sources of energy;
warranty or unanticipated service issues we may experience;
the environmental consciousness and perceived value of environmental programs to our customers;
the size of our expansion plans in comparison to our existing capital base and the scope and history of operations;
the availability and amount of tax incentives, credits, subsidies or other programs; and
the other factors set forth in this section.
Several of these factors are largely outside our control, and any negative perceptions about our liquidity or long-term business prospects, even if unfounded, would likely harm our business.
A material decrease in the retail price of utility-generated electricity or an increase in the price of natural gas would affect demand for our Energy Servers.
We believe that a customer’s decision to purchase our Energy Servers is significantly influenced by the price, the price predictability of electricity generated by our Energy Servers in comparison to the retail price and the future price outlook of electricity from the local utility grid and other renewable energy sources. In some states and countries, the current cost of grid electricity, even together with available subsidies, does not render our product economically attractive. Furthermore, if the retail price of grid electricity does not increase over time at the rate that we or our customers expect, it could reduce demand for our Energy Servers and harm our business. Several factors could lead to a reduction in the price or future price outlook for grid electricity, including the impact of energy conservation initiatives that reduce electricity consumption, construction of additional power generation plants (including nuclear, coal or natural gas) and technological developments by others in the electric power industry which could result in electricity being available at costs lower than those that can be achieved from our Energy Servers.
Furthermore, an increase in the price of natural gas or curtailment of availability could make our Energy Servers less economically attractive to potential customers and reduce demand.
We currently face and will continue to face significant competition.
We compete for customers, financing partners and incentive dollars with other electric power providers. Many providers of electricity, such as traditional utilities and other companies offering distributed generation products, have longer operating

histories, have customer incumbency advantages, have access to and influence with local and state governments and well as having access to more capital resources than do we. Significant developments in alternative technologies, such as energy storage, wind, solar or hydro power generation, or improvements in the efficiency or cost of traditional energy sources including coal, oil, natural gas used in combustion or nuclear power, may materially and adversely affect our business and prospects in ways we cannot anticipate. We may also face new competitors who are not currently in the market. If we fail to adapt to changing market conditions and to compete successfully with grid electricity or new competitors, our growth will be limited which would adversely affect our business results.
Our future success depends in part on our ability to increase our production capacity and we may not be able to do so in a cost-effective manner.
To the extent we are successful in growing our business, we may need to increase our production capacity. Our ability to plan, construct and equip additional manufacturing facilities is subject to significant risks and uncertainties, including the following:
The expansion or construction of any manufacturing facilities will be subject to the risks inherent in the development and construction of new facilities, including risks of delays and cost overruns as a result of factors outside our control such as delays in government approvals, burdensome permitting conditions and delays in the delivery of manufacturing equipment and subsystems that we manufacture or obtain from suppliers.
It may be difficult to expand our business internationally without additional manufacturing facilities located outside the United States. Adding manufacturing capacity in any international location will subject us to new laws and regulations including those pertaining to labor and employment, environmental and export import. In addition, it brings with it the risk of managing larger scale foreign operations.
We may be unable to achieve the production throughput necessary to achieve our target annualized production run rate at our current and future manufacturing facilities.
Manufacturing equipment may take longer and cost more to engineer and build than expected, and may not operate as required to meet our production plans.
We may depend on third-party relationships in the development and operation of additional production capacity, which may subject us to the risk that such third parties do not fulfill their obligations to us under our arrangements with them.
We may be unable to attract or retain qualified personnel.
If we are unable to expand our manufacturing facilities, we may be unable to further scale our business. If the demand for our Energy Servers or our production output decreases or does not rise as expected, we may not be able to spread a significant amount of our fixed costs over the production volume, thereby increasing our per unit fixed cost, which would have a negative impact on our financial condition and our results of operations.
We have, in some instances, entered into long-term supply agreements that could result in insufficient inventory and negatively affect our results of operations.
We have entered into long-term supply agreements with certain suppliers. Some of these supply agreements provide for fixed or inflation-adjusted pricing, and substantial prepayment obligations. If our suppliers provide insufficientobligations and in a few cases, supplier purchase commitments. These arrangements could mean that we end up paying for inventory that we did not need or that was at a higher price than the level of quality required to meet customer demand or if our suppliers are unable or unwilling to provide us with the contracted quantities, as we have limited or in some case no alternatives for supply, our results of operations could be materially and negatively impacted.market. Further, we face significant specific counterparty risk under long-term supply agreements when dealing with suppliers without a long, stable production and financial history. Given the uniqueness of our product, many of our suppliers do not have a long operating history and are private companies that may not have substantial capital resources. In the event any such supplier experiences financial difficulties, it may be difficult or impossible, or may require substantial time and expense, for us to recover any or all of our prepayments. We do not know whether we will be able to maintain long-term supply relationships with our critical suppliers or whether we may secure new long-term supply agreements. Additionally, many of our parts and materials are procured from foreign suppliers, which exposes us to risks including unforeseen increases in costs or interruptions in supply arising from changes in applicable international trade regulations such as taxes, tariffs or quotas. Any of the foregoing could materially harm our financial condition and our results of operations.
We face supply chain competition, including competition from businesses in other industries, which could result in insufficient inventory and negatively affect our results of operations.
Certain of our suppliers also supply parts and materials to other businesses including businesses engaged in the production of consumer electronics and other industries unrelated to fuel cells. As a relatively low-volume purchaser of certain of these parts and materials, we may be unable to procure a sufficient supply of the items in the event that our suppliers fail to

produce sufficient quantities to satisfy the demands of all of their customers, which could materially harm our financial condition and our results of operations.
We, and some of our suppliers, obtain capital equipment used in our manufacturing process from sole suppliers and, if this equipment is damaged or otherwise unavailable, our ability to deliver our Energy Servers on time will suffer.
Some of the capital equipment used to manufacture our products and some of the capital equipment used by our suppliers have been developed and made specifically for us, are not readily available from multiple vendors, and would be difficult to repair or replace if they did not function properly. If any of these suppliers were to experience financial difficulties or go out of business or if there were any damage to or a breakdown of our manufacturing equipment and we could not obtain replacement equipment in a timely manner, our business would suffer. In addition, a supplier’s failure to supply this equipment in a timely manner with adequate quality and on terms acceptable to us could disrupt our production schedule or increase our costs of production and service.
If we are not able to continue to reducePossible new tariffs could have a material adverse effect on our cost structure inbusiness.
Our business is dependent on the future, our ability to become profitable may be impaired.
We must continue to reduce the manufacturing costsavailability of raw materials and components for our Energy Servers, to expand our market. Additionally, certain of our existing service contracts were entered into basedparticularly electrical components common in the semiconductor industry, specialty steel products / processing and raw materials. Recently imposed tariffs on projections regarding service costs reductions that assume continued advances in our manufacturingsteel and services processes which we may be unable to realize. While wealuminum imports have been successful in reducing our manufacturing and services costs to date,increased the cost of components and raw materials for example, could increase inour Energy Servers and decreased the future. Any such increases could slow our growth and cause our financial results and operational metrics to suffer. In addition, we may face increases in our other expenses including increases in wagesavailable supply. Additional new tariffs or other labor costs as well as installation, marketing, salestrade protection measures which are proposed or related costs. We may continue to make significant investments to drive growth inthreatened and the future. In order to expand into electricity markets in which the pricepotential escalation of electricity from the grid is lower while still maintaininga trade war and retaliation measures could have a material adverse effect on our current margins, we will need to continue to reduce our costs. Increases in any of these costs or our failure to achieve projected cost reductions could adversely affect ourbusiness, results of operations and financial conditioncondition.
Although we currently maintain alternative sources for raw materials, our business is subject to the risk of price fluctuations and harmperiodic delays in the delivery of certain raw materials, which tariffs may exacerbate. Disruptions in the supply of raw materials and components could temporarily impair our ability to manufacture our Energy Servers for our customers or require us to pay higher prices in order to obtain these raw materials or components from other sources, which could affect our business and prospects. If we are unableour results of operations. While it is too early to reducepredict how the recently enacted tariffs on imported steel will impact our cost structure inbusiness, the future, we may not be able to achieve profitability, whichimposition of tariffs on items imported by us from China or other countries could increase our costs and could have a material adverse effect on our business and our prospects.results of operations.
If we fail
Risks Relating to manage our growth effectively, our business and operating results may suffer.Government Incentive Programs
Our current growthbusiness currently depends on the availability of rebates, tax credits and future growth plans may make it difficult for usother financial incentives, and the reduction, modification, or elimination of such benefits could cause our revenue to efficiently operatedecline and harm our business, challenging us to effectively manage our capital expenditures and control our costs while we expand our operations to increase our revenue. If we experience significant growth in orders without improvements in automation and efficiency, we may need additional manufacturing capacity and wefinancial results.
The U.S. federal government and some of our suppliers may need additionalstate and capital intensive equipment. Any growth in manufacturing must include a scaling of quality control as the increase in production increases the possible impact of manufacturing defects. In addition, any growth in the volume of saleslocal governments provide incentives to end users and purchasers of our Energy Servers in the form of rebates, tax credits, and other financial incentives, such as system performance payments and payments for renewable energy credits associated with renewable energy generation. In addition, some countries outside the U.S. also provide incentives to end users and purchasers of our Energy Servers. We currently have operations and sell our Energy Servers in Japan, China, India, and the Republic of Korea, collectively our Asia Pacific region, where Renewable Portfolio Standards ("RPS") are in place to promote the adoption of renewable power generation, including fuel cells. Our Energy Servers have qualified for tax exemptions, incentives, or other customer incentives in many states including the states of California, Connecticut, Massachusetts, New Jersey and New York. Some states have utility procurement programs and/or renewable portfolio standards for which our technology is eligible. Our Energy Servers are currently installed in eleven U.S. states, each of which may outpacehave its own enabling policy framework. We rely on these governmental rebates, tax credits, and other financial incentives to significantly lower the effective price of the Energy Servers to our customers in the U. S. and the Asia Pacific region. Our financing partners and Equity Investors in Bloom Electrons programs may also take advantage of these financial incentives, lowering the cost of capital and energy to our customers. However, these incentives or RPS may expire on a particular date, end when the allocated funding is exhausted, or be reduced or terminated as a matter of regulatory or legislative policy.
For example, the previous federal investment tax credit ("ITC"), a federal tax incentive for fuel cell production, expired on December 31, 2016. Without the availability of the ITC benefit incentive, we lowered the price of our Energy Servers to ensure the economics to our customers would remain the same as it was prior to losing the ITC benefit, adversely affecting our gross profit. While the ITC was reinstated by the U.S Congress on February 9, 2018 and made retroactive to January 1, 2017, under current law it will phase out on December 31, 2022.
As another example, the California Self Generation Incentive Program ("SGIP") is a program administered by the California Public Utilities Commission ("CPUC") which provides incentives to investor-owned utility customers that install

eligible distributed energy resources. In July 2016, the CPUC modified the SGIP to provide a smaller allocation of the incentives available to generating technologies such as our Energy Servers and a larger allocation to storage technologies. As modified, the SGIP will require all eligible power generation sources consuming natural gas to use a minimum 50% biogas to receive SGIP funds in 2019 and 100% in 2020. In addition, the CPUC provided a further limitation on the available allocation of funds that any one participant may claim under the SGIP. The SGIP will expire on January 21, 2021 absent any extension. Our customer sites accepted benefiting from the SGIP represented approximately 0% and 18% of total sites accepted for the three months ended March 31, 2019 and 2018, respectively.
Changes in federal, state, or local programs or the RPS in the Asia Pacific region could reduce demand for our Energy Servers, impair sales financing, and adversely impact our business results. The continuation of these programs depends upon political support which to date has been bipartisan and durable. Nevertheless, one set of political activists aggressively seeks to eliminate these programs while another set seeks to deny access to these programs for any technology that relies on natural gas, regardless of the technology’s positive contribution to reducing air pollution, reducing carbon emissions or enabling electric service to be more reliable and resilient.
We rely on tax equity financing arrangements to realize the benefits provided by investment tax credits and accelerated tax depreciation and, in the event these programs are terminated, our financial results could be harmed.
We expect that any Energy Server deployments through financed transactions (including our Bloom Electrons programs, our leasing programs and any Third-Party PPA Programs) will receive capital from financing parties ("Equity Investors") who derive a significant portion of their economic returns through tax benefits. Equity Investors are generally entitled to substantially all of the project’s tax benefits, such as those provided by the ITC and Modified Accelerated Cost Recovery System ("MACRS") or bonus depreciation, until the Equity Investors achieve their respective agreed rates of return. The number of and available capital from potential Equity Investors is limited, we compete with other energy companies eligible for these tax benefits to access such investors, and the availability of capital from Equity Investors is subject to fluctuations based on factors outside of our control such as macroeconomic trends and changes in applicable taxation regimes. Concerns regarding our limited operating history, lack of profitability and that we are only the party who can perform operations and maintenance on our energy servers have made it difficult to attract investors in the past. Our ability to engage sufficientobtain additional financing in the future depends on the continued confidence of banks and experienced personnel to manage the higher number of installations and to engage contractors to complete installations on a timely basis andother financing sources in accordance with our expectations and standards. Any failure to manage our growth effectively could materially and adversely affect our business model, the market for our prospects,Energy Servers, and the continued availability of tax benefits applicable to our operating resultsEnergy Servers. In addition, conditions in the general economy and our financial condition. Our future operating results depend to a large extent on our ability to manage this expansion and growth successfully.
Our failure to protect our intellectual property rights may undermine our competitive position, and litigation to protect our intellectual property rights may be costly.
Although we have taken many protective measures to protect our trade secrets including agreements, limited access, segregation of knowledge, password protections and other measures, policing unauthorized use of proprietary technology can be difficult and expensive. For example, many of our engineers reside in California where it is not legally permissible to prevent them from working for a competitor if and when one should exist. Also, litigation may be necessary to enforce our intellectual property rights, to protect our trade secrets, or to determine the validity and scope of the proprietary rights of others. Such litigationcredit markets may result in our intellectual property rights being challenged, limited in scopethe contraction of available tax equity financing. If we are unable to enter into tax equity financing agreements with attractive pricing terms, or declared invalid or unenforceable. We cannot be certain that the outcome of any litigation will be in our favor, and an adverse determination in any such litigation could impair our intellectual property rights and may harm our business, our prospects and our reputation.
We rely primarily on patent, trade secret and trademark laws and non-disclosure, confidentiality and other types of contractual restrictions to establish, maintain and enforce our intellectual property and proprietary rights. However, our rights under these laws and agreements afford us only limited protection and the actions we take to establish, maintain and enforce our intellectual property rights may not be adequate. For example, our trade secrets and other confidential information could be disclosed in an unauthorized manner to third parties, our owned or licensed intellectual property rights could be challenged, invalidated, circumvented, infringed or misappropriated or our intellectual property rights may not be sufficient to provide us

with a competitive advantage, any of which could have a material adverse effect on our business, financial condition or operating results. In addition, the laws of some countries do not protect proprietary rights as fully as do the laws of the United States. As a result,at all, we may not be able to protectobtain the capital needed to fund our proprietary rights adequately abroad.
Our patent applications may not result in issued patentsfinancing programs or use the tax benefits provided by the ITC and our issued patents may not provide adequate protection,MACRS depreciation, which may have a material adverse effect on our abilitycould make it more difficult for customers to prevent others from commercially exploiting products similar to ours.
We cannot be certain that our pending patent applications will result in issued patents or that anyfinance the purchase of our issued patents will afford protection against a competitor. The status of patents involves complex legal and factual questions, and the breadth of claims allowed is uncertain. As a result, we cannot be certain that the patent applications that we file will result in patents being issued or that our patents and any patents that may be issued to us in the future will afford protection against competitors with similar technology. In addition, patent applications filed in foreign countries are subject to laws, rules and procedures that differ from those of the United States, and thus we cannot be certain that foreign patent applications related to issued U.S. patents will be issued in other regions. Furthermore, even if these patent applications are accepted and the associated patents issued, some foreign countries provide significantly less effective patent enforcement than in the United States.
In addition, patents issued to us may be infringed upon or designed around by others and others may obtain patents that we need to license or design around, either of which would increase costs and may adversely affect our business, our prospects, and our operating results.
We may need to defend ourselves against claims that we infringe, have misappropriated or otherwise violate the intellectual property rights of others, which may be time-consuming and would causeEnergy Servers. Such circumstances could also require us to incur substantial costs.
Companies, organizations, or individuals including our competitors may hold or obtain patents, trademarks or other proprietary rights that they may inreduce the future believe are infringed by our products or services. Althoughprice at which we are not currently subjectable to any claims related to intellectual property, these companies holding patents or other intellectual property rights allegedly relating to our technologies could, in the future, make claims or bring suits alleging infringement, misappropriation or other violations of such rights, or otherwise assert their rights and by seeking licenses or injunctions. Several of the proprietary components used insell our Energy Servers have been subjected to infringement challenges in the past. We also generally indemnify our customers against claims that the products we supply infringe, misappropriate or otherwise violate third party intellectual property rights, and we may therefore be required to defend our customers against such claims. If a claim is successfully brought in the future and we or our products are determined to have infringed, misappropriated or otherwise violated a third party’s intellectual property rights, we may be required to do one or more of the following:
cease selling or using our products that incorporate the challenged intellectual property;
pay substantial damages (including treble damages and attorneys’ fees if our infringement is determined to be willful);
obtain a license from the holder of the intellectual property right, which may not be available on reasonable terms or at all; or
redesign our products or means of production, which may not be possible or cost-effective.
Any of the foregoing could adversely affect our business, prospects, operating results and financial condition. In addition, any litigation or claims, whether or not valid, could harm our reputation, result in substantial costs and divert resources and management attention.
We also license technology from third parties and incorporate components supplied by third parties into our products. We may face claims that our use of such technology or components infringes or otherwise violates the rights of others, which would subject us to the risks described above. We may seek indemnification from our licensors or suppliers under our contracts with them, but our rights to indemnification or our suppliers’ resources may be unavailable or insufficient to cover our costs and losses.
If we are unable to attract and retain key employees and hire qualified management, technical, engineering and sales personnel, our ability to compete and successfully grow our business, could be harmed.
We believe that our success and our ability to reach our strategic objectives are highly dependent on the contributions of our key management, technical, engineering and sales personnel. The loss of the services of any of our key employees could disrupt our operations, delay the development and introduction of our products and services and negatively impact our business, prospects and operating results. In particular, we are highly dependent on the services of Dr. Sridhar, our President and Chief Executive Officer, and other key employees. None of our key employees is bound by an employment agreement for any specific term. We cannot assure you that we will be able to successfully attract and retain senior leadership necessary to grow our business. Furthermore, there is increasing competition for talented individuals in our field, and competition for qualified

personnel is especially intense in the San Francisco Bay Area where our principal offices are located. Our failure to attract and retain our executive officers and other key technology, sales, marketing and support personnel could adversely impact our business, our prospects, our financial condition, and our operating results. In addition, we do not have “key person” life insurance policies covering anyresults of our officers or other key employees.operations.
Risks Related to Legal Matters and Regulations
We are subject to various environmental laws and regulations that could impose substantial costs upon us and cause delays in building our manufacturing facilities.
We are subject to national, state, and local environmental laws and regulations as well as environmental laws in those foreign jurisdictions in which we operate. Environmental laws and regulations can be complex and may often change. These laws can give rise to liability for administrative oversight costs, cleanup costs, property damage, bodily injury, fines, and penalties. Capital and operating expenses needed to comply with environmental laws and regulations can be significant, and violations may result in substantial fines and penalties or third-party damages. In addition, ensuring we are in compliance with applicable environmental laws could require significant time and management resources and could cause delays in our ability to build out, equip and operate our facilities as well as service our fleet, which would adversely impact our business, our prospects, our financial condition, and our operating results. In addition, environmental laws and regulations such as the Comprehensive Environmental Response, Compensation and Liability Act in the United States impose liability on several grounds including for the investigation and cleanup of contaminated soil and ground water, for building contamination, for impacts to human health and for damages to natural resources. If contamination is discovered in the future at properties formerly owned or operated by us or currently owned or operated by us, or properties to which hazardous substances were sent by us, it could result in our liability under environmental laws and regulations. Many of our customers who purchase our Energy Servers have high sustainability standards, and any environmental noncompliance by us could harm our reputation and impact a current or potential customer’s buying decision. The costs of complying with environmental laws, regulations, and customer requirements, and any claims concerning noncompliance or liability with respect to contamination in the future, could have a material adverse effect on our financial condition or our operating results.

The installation and operation of our Energy Servers are subject to environmental laws and regulations in various jurisdictions, and there is uncertainty with respect to the interpretation of certain environmental laws and regulations to our Energy Servers, especially as these regulations evolve over time.
Bloom is committed to compliance with applicable environmental laws and regulations including health and safety standards, and we continually review the operation of our Energy Servers for health, safety, and environmental compliance. Our Energy Servers, like other fuel cell technology-based products of which we are aware, produce small amounts of hazardous wastes and air pollutants, and we seek to ensure that they are handled in accordance with applicable regulatory standards.
Maintaining compliance with laws and regulations can be challenging given the changing patchwork of environmental laws and regulations that prevail at the federal, state, regional, and local level. Most existing environmental laws and regulations preceded the introduction of our innovative fuel cell technology and were adopted to apply to technologies existing at the time, namely large coal, oil, or gas-fired power plants. Currently, there is generally little guidance from these agencies on how certain environmental laws and regulations may or may not be applied to our technology.
For example, natural gas, which is the primary fuel used in our Energy Servers, contains benzene, which is classified as a hazardous waste if it exceeds 0.5 milligrams (mg)("mg") per liter. A small amount of benzene found in the public natural gas pipeline (equivalent to what is present in one gallon of gasoline in an automobile fuel tank which isare exempt from federal regulation) is collected by the gas cleaning units contained in our Energy Servers which isare typically replaced once every 18 to 24 months by us from customers’ sites. From 2010 to late 2016 and in the regular course of maintenance of the Energy Servers, we periodically replaced the units in our servers under a federal environmental exemption that permitted the handling of such units without manifesting the contents as containing a hazardous waste. Although at the time we believed that we operated under the exemption with the approval of two states that had adopted the federal exemption, the federalU.S. Environmental Protection Agency ("EPA") issued guidance for the first time in late 2016 that differed from our belief and conflicted with the state approvals we had obtained even though we had operated under the exemption since 2010. We have complied with the new guidance and, given the comparatively small quantities of benzene produced, we do not anticipate significant additional costs or risks from our compliance with the revised 2016 guidance. However, the EPA is seekinghas asked us to show cause why it should not collect approximately $1.0 million in fines from us for the prior period, which we are contesting. Additionally, we paid a nominal fine to an agency in a different state under thethat state’s environmental laws relating to the operation of our Energy Server in that state under the exemption prior to the issuance of the revised EPA guidance.
Another example relates to the very small amounts of chromium in hexavalent form, or CR+6, which our Energy Servers emit.emit at nanometer scale. This occurs any time a steel super alloy is exposed to high temperatures. CR+6 is found in small samplesconcentrations in the air generally. However, exposure to high or significant concentrations over prolonged periods of time can be carcinogenic. While

the small amount of chromium emitted by our Energy Servers is initially in the hexavalent form, it converts to a non-toxic trivalent form, or CR+3, rapidly after it leaves the Energy Server. In tests we have conducted, air measurements taken 10 meters from an Energy Server show that the CR+6 is largely converted.
Our Energy Servers do not present any significant health hazard based on our modeling, testing methodology, and measurements. There are several supporting elements to this position including that the emissions from our Energy Servers are in very low concentrations, are emitted as nano-particles that convert to the non-hazardous form CR+3 rapidly, are quickly dispersed into the air, and are not emitted in close proximity to locations where people would be expected to have a prolonged exposure. Nevertheless, we have engineered a technology solution that we are deploying.
Several states in which we currently operate, including California, require permits for emissions of hazardous air pollutants based on the quantity of emissions, most of which require permits only for quantities of emissions that are higher than those observed from our Energy Servers. Other states in which we operate, including New York, New Jersey, and North Carolina, have specific exemptions for fuel cells. Some states in which we operate have CR+6 limits which are an order of magnitude over our operating range. Within California, the Bay Area Air Quality Management District ("BAAQMD"), requires a permit for emissions that are more than .000510.00051 lbs/year. Other California regulations require that levels of CR+6 be below .000050.00005 µg/m³ (the, which is the level required by Proposition 65)65 and which requires notification of the presence of CR+6 unless it can be shown to be at levels that do not pose a significant health risk. We have determined that the standards applicable in California in this regard are more stringent than those in any other state or foreign location in which we have installed Energy Servers to date.date, therefore, deployment of our solution has been focused on California's standards.
There are generally no relevant environmental testing methodology guidelines for a technology such as ours. The standard test method for analyzing emissions cannot be readily applied to our Energy Servers because it would require inserting a probe into an emission stack. Our servers do not have emission stacks; therefore, we have to construct an artificial stack on top of our server in order to conduct a test. If we used the testing methodology similar to what the air districts have used in other large scale industrial products, it would show that we would need to reduce the emissions of CR+6 from our Energy

Servers to meet the most stringent requirements. However, we employed a modified test method that is designed to capture the actual operating conditions of our Energy Servers and its distinctly different design from legacy power plants and industrial equipment. Based on our modeling, measured results and analysis, we believe we are in compliance with State of California air regulations.
We will work with the California Air Districts and seek to obtain their agreement that we are in compliance. Should the regulators disagree, we have engineered a technology solution that provides an alternate route to compliance. We are already deploying this technology solution in new Energy Servers in California and we are ready to deploy it in existing Energy Servers. It will cost less than 0.1% of our product cost. However, it is possible that the California Air Districts will require us to abate or shut down the operations of certain of our existing Energy Servers on a temporary basis or will seek the imposition of monetary fines.
While we seek to comply with air quality and emission standards in every region in which we operate, it is possible that certain customers in other regions may request that we provide the new technology solution for their Energy Servers to comply with the stricter standards imposed by California even though they are not applicable and even though we are under no contractual obligation to do so. We will comply withplan to satisfy these requests.requests from customers. Failure or delay in attaining regulatory approval could result in our not being able to operate in a particular local jurisdiction.
These examples illustrate that our technology is moving faster than the regulatory process in many instances. It is possible that regulators could delay or prevent us from conducting our business in some way pending agreement on, and compliance with, shifting regulatory requirements. Such actions could delay the installation of Energy Servers, could result in fines, could require modification or replacement or could trigger claims of performance warranties and defaults under customer contracts that could require us to repurchase their Energy Servers, any of which could adversely affect our business, our financial performance, and our reputation. In addition, new laws or regulations or new interpretations of existing laws or regulations could present marketing, political or regulatory challenges and could require us to upgrade or retrofit existing equipment, which could result in materially increased capital and operating expenses.
Furthermore, we have not yet determined whether our Energy Servers will satisfy regulatory requirements in the other states in the U.S. and in international locations in which we do not currently sell Energy Servers but may pursue in the future.
As a fossil fuel-based technology, we may be subject to a heightened risk of regulation, to a potential for the loss of certain incentives, and to changes in our customers’ energy procurement policies.
Although the current generation of Bloom Energy Servers running on natural gas produce nearly 60% less carbon emissions compared to the average of U.S. combustion power generation, the operation of our Energy Servers does produce

carbon dioxide ("CO2")(CO2), which has been shown to be a contributing factor to global climate change. As such, we may be negatively impacted by CO2-related changes in applicable laws, regulations, ordinances, or other rules, or the requirements of the incentive programs on which we and our customers currently rely. Changes, or in some cases a lack of change, in any of the laws, regulations, ordinances, or other rules that apply to our installations and new technology could make it illegal or more costly for us or our customers to install and operate our Energy Servers on particular sites, thereby negatively affecting our ability to deliver cost savings to customers, or we could be prohibited from completing new installations or continuing to operate existing projects. Certain municipalities in California have already banned the use of distributed generation products that utilize fossil fuel. Additionally, our customers’ and potential customers’ energy procurement policies may prohibit or limit their willingness to procure our Energy Servers. Our business prospects may be negatively impacted if we are prevented from completing new installations or our installations become more costly as a result of laws, regulations, ordinances, or other rules applicable to our Energy Servers, or by our customers’ and potential customers’ energy procurement policies.
Existing regulations and changes to such regulations impacting the electric power industry may create technical, regulatory, and economic barriers which could significantly reduce demand for our Energy Servers.
The market for electricity generation products is heavily influenced by U.S. federal, state, local, and foreign government regulations and policies as well as by internal policies and regulations of electric utility providers. These regulations and policies often relate to electricity pricing and technical interconnection of customer-owned electricity generation. These regulations and policies are often modified and could continue to change, which could result in a significant reduction in demand for our Energy Servers. For example, utility companies commonly charge fees to larger industrial customers for disconnecting from the electric grid or for having the capacity to use power from the electric grid for back-up purposes. These fees could change, thereby increasing the cost to our customers of using our Energy Servers and making them less economically attractive. In addition, our project with Delmarva Power & Light Company (Delmarva)("Delmarva") is subject to laws and regulations relating to electricity generation, transmission, and sale such as Federal Energy Regulatory Commission (FERC)("FERC") regulation under various federal energy regulatory laws, which requires FERC authorization to make wholesale sales of electric energy, capacity, and ancillary services. Also, several of our PPA Entities are subject to regulation under FERC with respect to market-based sales of electricity, which requires us to file notices and make other periodic filings with FERC, which increases our costs and subjects us to additional regulatory oversight.
PossibleAlthough we generally are not regulated as a utility, federal, state, and local government statutes and regulations concerning electricity heavily influence the market for our product and services. These statutes and regulations often relate to electricity pricing, net metering, incentives, taxation, and the rules surrounding the interconnection of customer-owned

electricity generation for specific technologies. In the United States, governments frequently modify these statutes and regulations. Governments, often acting through state utility or public service commissions, change and adopt different requirements for utilities and rates for commercial customers on a regular basis. Changes, or in some cases a lack of change, in any of the laws, regulations, ordinances, or other rules that apply to our installations and new tariffstechnology could have a material adverse effect onmake it more costly for us or our business.
Our business is dependent on the availability of raw materialscustomers to install and components foroperate our Energy Servers particularly electrical components commonon particular sites and, in the semiconductor industry, specialty steel products / processing and raw materials. The United States has recently imposed tariffs on steel and aluminum imports which may increase the cost of raw materials for our Energy Servers and decrease the available supply. The United States is also considering tariffs on additional items whichturn, could include items imported by us from China or other countries.
Although we currently maintain alternative sources for raw materials, our business is subject to the risk of price fluctuations and periodic delays in the delivery of certain raw materials, which tariffs may exacerbate. Disruptions in the supply of raw materials and components could temporarily impairnegatively affect our ability to manufacture our Energy Serversdeliver cost savings to customers for our customers or require us to pay higher prices in order to obtain these raw materials or components from other sources, which could thereby affect our business and our resultsthe purchase of operations. While it is too early to predict how the recently enacted tariffs on imported steel will impact our business, the imposition of tariffs on items imported by us from China or other countries could increase our costs and could have a material adverse effect on our business and our results of operations.electricity.
We may become subject to product liability claims which could harm our financial condition and liquidity if we are not able to successfully defend or insure against such claims.
We may in the future become subject to product liability claims. Our Energy Servers are considered high energy systems because they use flammable fuels and may operate at 480 volts. Although our Energy Servers are certified to meet ANSI, IEEE, ASME, and NFPA design and safety standards, if not properly handled in accordance with our servicing and handling standards and protocols, there could be a system failure and resulting liability. These claims could require us to incur significant costs to defend. Furthermore, any successful product liability claim could require us to pay a substantial monetary award. Moreover, a product liability claim could generate substantial negative publicity about our company and our Energy Servers, which could harm our brand, our business prospects, and our operating results. While we maintain product liability insurance, our insurance may not be sufficient to cover all potential product liability claims. Any lawsuit seeking significant monetary damages either in excess of our coverage or outside of our coverage may have a material adverse effect on our business and our financial condition.
Current or future litigation or administrative proceedings could have a material adverse effect on our business, our financial condition and our results of operations.

We have been and continue to be involved in legal proceedings, administrative proceedings, claims, and other litigation that arise in the ordinary course of business. Purchases of our products have also been the subject of litigation. For example, in 2011, an amendment to the Delaware Renewable Energy Portfolio Statute was enacted to permit the Delaware public service utility, Delmarva, to meet its renewable energy standards using energy generated by fuel cells manufactured and operated in Delaware. This statute required Delmarva to charge a tariff to its ratepayorsrate payers to pay for certain costs of providers of such energy generated by fuel cells. In 2012, plaintiffs FuelCell Energy Inc. and John A. Nichols filed suit against Delaware Governor Jack Markell and the Delaware Public Service Commission in the U.S. District Court for Delaware claiming that the 2011 amendment to the statute discriminated against interstate fuel cell providers and subsidized us for building a manufacturing facility in Delaware to manufacture fuel cells. We were not named as a party to this lawsuit and the litigation was ultimately settled. As another example, in July 2018, we received a Statement of Claim from two former executives of Advanced Equities, Inc. seeking to compel arbitration and alleging a breach of a confidential agreement from June 2014. This Statement of Claim sought, among other things, to void the indemnification and confidentiality provisions under the confidential agreement and to recover attorneys’ fees and costs. The Statement of Claim was dismissed without prejudice on July 22, 2018. In addition, since our Energy Server is a new type of product in a nascent market, we have in the past needed and may in the future need to seek the amendment of existing regulations, or in some cases the creation of new regulations, in order to operate our business in some jurisdictions. Such regulatory processes may require public hearings concerning our business, which could expose us to subsequent litigation.
Unfavorable outcomes or developments relating to proceedings to which we are a party or transactions involving our products such as judgments for monetary damages, injunctions, or denial or revocation of permits, could have a material adverse effect on our business, our financial condition, and our results of operations. In addition, settlement of claims could adversely affect our financial condition and our results of operations.
A breach or
Risks Relating to Our Intellectual Property
Our failure to protect our intellectual property rights may undermine our competitive position, and litigation to protect our intellectual property rights may be costly.
Although we have taken many protective measures to protect our trade secrets including agreements, limited access, segregation of knowledge, password protections, and other measures, policing unauthorized use of proprietary technology can be difficult and expensive. For example, many of our networksengineers reside in California where it is not legally permissible to prevent them from working for a competitor if and when one should exist. Also, litigation may be necessary to enforce our intellectual property rights, to protect our trade secrets, or computerto determine the validity and scope of the proprietary rights of others. Such litigation may result in our intellectual property rights being challenged, limited in scope, or data management systemsdeclared invalid or

unenforceable. We cannot be certain that the outcome of any litigation will be in our favor, and an adverse determination in any such litigation could damageimpair our operationsintellectual property rights, our business, our prospects, and our reputation.
Our business is dependentWe rely primarily on patent, trade secret, and trademark laws and non-disclosure, confidentiality, and other types of contractual restrictions to establish, maintain, and enforce our intellectual property and proprietary rights. However, our rights under these laws and agreements afford us only limited protection and the securityactions we take to establish, maintain, and efficacy ofenforce our networks and computer and data management systems.intellectual property rights may not be adequate. For example, allour trade secrets and other confidential information could be disclosed in an unauthorized manner to third parties, our owned or licensed intellectual property rights could be challenged, invalidated, circumvented, infringed, or misappropriated or our intellectual property rights may not be sufficient to provide us with a competitive advantage, any of our Energy Servers are connected to and controlled and monitored by our centralized remote monitoring service, and we rely on our internal computer networks for many of the systems we use to operate our business generally. Although we take protective measures and endeavor to modify them as circumstances warrant, the security of our infrastructure, including the network that connects our Energy Servers to our remote monitoring service, may be vulnerable to breaches, unauthorized access, misuse, computer viruses or other malicious code and cyber-attacks thatwhich could have a material adverse impacteffect on our business, financial condition, or operating results. In addition, the laws of some countries do not protect proprietary rights as fully as do the laws of the United States. As a result, we may not be able to protect our proprietary rights adequately abroad.
Our patent applications may not result in issued patents, and our issued patents may not provide adequate protection, either of which may have a material adverse effect on our ability to prevent others from commercially exploiting products similar to ours.
We cannot be certain that our pending patent applications will result in issued patents or that any of our issued patents will afford protection against a competitor. The status of patents involves complex legal and factual questions, and the breadth of claims allowed is uncertain. As a result, we cannot be certain that the patent applications that we file will result in patents being issued or that our patents and any patents that may be issued to us in the future will afford protection against competitors with similar technology. In addition, patent applications filed in foreign countries are subject to laws, rules, and procedures that differ from those of the United States, and thus we cannot be certain that foreign patent applications related to issued U.S. patents will be issued in other regions. Furthermore, even if these patent applications are accepted and the associated patents issued, some foreign countries provide significantly less effective patent enforcement than in the United States.
In addition, patents issued to us may be infringed upon or designed around by others and others may obtain patents that we need to license or design around, either of which would increase costs and may adversely affect our business, our prospects, and our operating results.
We may need to defend ourselves against claims that we infringed, misappropriated, or otherwise violated the intellectual property rights of others, which may be time-consuming and would cause us to incur substantial costs.
Companies, organizations, or individuals, including our competitors, may hold or obtain patents, trademarks, or other proprietary rights that they may in the future believe are infringed by our products or services. Although we are not currently subject to any claims related to intellectual property, these companies holding patents or other intellectual property rights allegedly relating to our technologies could, in the future, make claims or bring suits alleging infringement, misappropriation, or other violations of such rights, or otherwise assert their rights and by seeking licenses or injunctions. Several of the proprietary components used in our Energy Servers have been subjected to infringement challenges in the past. We also generally indemnify our customers against claims that the products we supply infringe, misappropriate, or otherwise violate third party intellectual property rights, and we therefore may be required to defend our customers against such claims. If a claim is successfully brought in the future and we or our products are determined to have infringed, misappropriated, or otherwise violated a third party’s intellectual property rights, we may be required to do one or more of the following:
cease selling or using our products that incorporate the challenged intellectual property;
pay substantial damages (including treble damages and attorneys’ fees if our infringement is determined to be willful);
obtain a license from the holder of the intellectual property right, which may not be available on reasonable terms or at all; or
redesign our products or means of production, which may not be possible or cost-effective.
Any of the foregoing could adversely affect our business, prospects, operating results, and financial condition. In addition, any litigation or claims, whether or not valid, could harm our reputation, result in substantial costs and divert resources and management attention.
We also license technology from third parties and incorporate components supplied by third parties into our products. We may face claims that our use of such technology or components infringes or otherwise violates the rights of others, which would subject us to the risks described above. We may seek indemnification from our licensors or suppliers under our contracts with them, but our rights to indemnification or our suppliers’ resources may be unavailable or insufficient to cover our costs and losses.

Risks Relating to Our Financial Condition and Operating Results
We have incurred significant losses in the past and we may not be profitable for the foreseeable future.
Since our inception in 2001, we have incurred significant net losses and have used significant cash in our business. As of March 31, 2019, we had an accumulated deficit of $2.7 billion. We expect to continue to expand our operations, including by investing in manufacturing, sales and marketing, research and development, staffing systems, and infrastructure to support our growth. We anticipate that we will incur net losses for the foreseeable future. Our ability to achieve profitability in the future will depend on a number of factors, including:
growing our sales volume;
increasing sales to existing customers and attracting new customers;
attracting and retaining financing partners who are willing to provide financing for sales on a timely basis and with attractive terms;
continuing to improve the useful life of our fuel cell technology and reducing our warranty servicing costs;
reducing the cost of producing our Energy Servers;
improving the efficiency and predictability of our installation process;
improving the effectiveness of our sales and marketing activities;
attracting and retaining key talent in a competitive marketplace; and
the amount of stock based compensation recognized in the period.
Even if we do achieve profitability, we may be unable to sustain or increase our profitability in the future.
Our financial condition and results of operations and other key metrics are likely to fluctuate on a quarterly basis in future periods, which could cause our results for a particular period to fall below expectations, resulting in a severe decline in the price of our Class A common stock.
Our financial condition and results of operations and other key metrics have fluctuated significantly in the past and may continue to fluctuate in the future due to a variety of factors, many of which are beyond our control. For example, the amount of product revenue we recognize in a given period is materially dependent on the volume of installations of our Energy Servers in that period and the field. A breachtype of financing used by the customer.
In addition to the other risks described herein, the following factors could also cause our financial condition and results of operations to fluctuate on a quarterly basis:
the timing of installations, which may depend on many factors such as availability of inventory, product quality or failureperformance issues, or local permitting requirements, utility requirements, environmental, health, and safety requirements, weather, and customer facility construction schedules;
size of particular installations and number of sites involved in any particular quarter;
the mix in the type of purchase or financing options used by customers in a period, and the rates of return required by financing parties in such period;
whether we are able to structure our sales agreements in a manner that would allow for the product and installation revenue to be recognized up front at acceptance;
delays or cancellations of Energy Server installations;
fluctuations in our service costs, particularly due to unaccrued costs of servicing and maintaining Energy Servers;
weaker than anticipated demand for our Energy Servers due to changes in government incentives and policies or due to other conditions;
fluctuations in our research and development expense, including periodic increases associated with the pre-production qualification of additional tools as we expand our production capacity;
interruptions in our supply chain;

the length of the sales and installation cycle for a particular customer;
the timing and level of additional purchases by existing customers;
unanticipated expenses or installation delays associated with changes in governmental regulations, permitting requirements by local authorities at particular sites, utility requirements and environmental, health, and safety requirements;
disruptions in our sales, production, service or other business activities resulting from disagreements with our labor force or our inability to attract and retain qualified personnel; and
unanticipated changes in federal, state, local, or foreign government incentive programs available for us, our customers, and tax equity financing parties.
Fluctuations in our operating results and cash flow could, among other things, give rise to short-term liquidity issues. In addition, our revenue, key operating metrics, and other operating results in future quarters may fall short of the expectations of investors and financial analysts, which could have an adverse effect on the price of our networks or computer or data management systems dueClass A common stock.
If we fail to intentional actions such as cyber-attacks, negligence or other reasons could seriously disruptmanage our growth effectively, our business and operating results may suffer.
Our current growth and future growth plans may make it difficult for us to efficiently operate our business, challenging us to effectively manage our capital expenditures and control our costs while we expand our operations or could affectto increase our ability torevenue. If we experience a significant growth in orders without improvements in automation and efficiency, we may need additional manufacturing capacity and we and some of our suppliers may need additional and capital intensive equipment. Any growth in manufacturing must include a scaling of quality control or to assessas the performanceincrease in production increases the possible impact of manufacturing defects. In addition, any growth in the fieldvolume of sales of our Energy Servers may outpace our ability to engage sufficient and experienced personnel to manage the higher number of installations and to engage contractors to complete installations on a timely basis and in accordance with our expectations and standards. Any failure to manage our growth effectively could result in disruption to our businessmaterially and potentially legal liability. These events could result in significant costs or reputational consequences.
Our headquarters and other facilities are located in an active earthquake zone, and an earthquake or other types of natural disasters or resource shortages could disrupt and harm our results of operations.
We conduct a majority of our operations in the San Francisco Bay area in an active earthquake zone, and certain of our facilities are located within known flood plains. The occurrence of a natural disaster such as an earthquake, drought, flood, localized extended outages of critical utilities or transportation systems or any critical resource shortages could cause a significant interruption in our business, damage or destroy our facilities, our manufacturing equipment, or our inventory, and cause us to incur significant costs, any of which could harmadversely affect our business, our financial condition,prospects, our operating results, and our financial condition. Our future operating results of operations. The insurance we maintain against fires, earthquakesdepend to a large extent on our ability to manage this expansion and other natural disasters may not be adequate to cover our losses in any particular case.
Expanding operations internationally could expose us to risks.
Although we currently primarily operate in the United States, we will seek to expand our business internationally. We currently have operations in Japan, China India and South Korea. Managing any international expansion will require additional resources and controls including additional manufacturing and assembly facilities. Any expansion internationally could subject our business to risks associated with international operations, including:
conformity with applicable business customs, including translation into foreign languages and associated expenses;
lack of availability of government incentives and subsidies;
challenges in arranging, and availability of, financing for our customers;
potential changes to our established business model;
cost of alternative power sources, which could be meaningfully lower outside the United States;

availability and cost of natural gas;
difficulties in staffing and managing foreign operations in an environment of diverse culture, laws and customers, and the increased travel, infrastructure and legal and compliance costs associated with international operations;
installation challenges which we have not encountered before which may require the development of a unique model for each country;
compliance with multiple, potentially conflicting and changing governmental laws, regulations and permitting processes including environmental, banking, employment, tax, privacy and data protection laws and regulations such as the EU Data Privacy Directive;
compliance with U.S. and foreign anti-bribery laws including the Foreign Corrupt Practices Act and the U.K. Anti-Bribery Act;
difficulties in collecting payments in foreign currencies and associated foreign currency exposure;
restrictions on repatriation of earnings;
compliance with potentially conflicting and changing laws of taxing jurisdictions where we conduct business and applicable U.S. tax laws as they relate to international operations, the complexity and adverse consequences of such tax laws and potentially adverse tax consequences due to changes in such tax laws; and
regional economic and political conditions.
As a result of these risks, any potential future international expansion efforts that we may undertake may not be successful.growth successfully.
If we discover a material weakness in our internal control over financial reporting or otherwise fail to maintain effective internal control over financial reporting, our ability to report our financial results on a timely and an accurate basis may adversely affect the market price of our Class A common stock.
The Sarbanes-Oxley Act of 2002 (Sarbanes-Oxley Act)("Sarbanes-Oxley Act") requires, among other things, that wepublic companies evaluate the effectiveness of ourtheir internal control over financial reporting and disclosure controls and procedures. As a recently public company and as an emerging growth company, we elected to delay adopting the requirements of the Sarbanes-Oxley Act as is our option under the Sarbanes-Oxley Act. Although we did not discover any material weaknesses in internal control over financial reporting at DecemberMarch 31, 2017,2019, subsequent testing by us or our independent registered public accounting firm, which has not yet performed an audit of our internal control over financial reporting, may reveal deficiencies in our internal control over financial reporting that are deemed to be material weaknesses. To comply with Section 404A, we may incur substantial cost, expend significant management time on compliance-related issues, and hire additional accounting, financial, and internal audit staff with appropriate public company experience and technical accounting knowledge. Moreover, if we are not able to comply with the requirements of Section 404A in a timely manner or if we or our independent registered public accounting firm identify deficiencies in our internal control over financial reporting that are deemed to be material weaknesses, we could be subject to sanctions or investigations by the Securities and Exchange Commission (SEC)("SEC") or other regulatory authorities, which would require additional financial and management resources. Any failure to maintain effective disclosure controls and procedures or internal control over financial reporting could have a material adverse effect on our business and operating results and cause a decline in the price of our Class A common stock. For further discussion on Section 404A compliance, see our Risk Factor: We are an “emerging growth company,” and we cannot be certain if the reduced disclosure requirements applicable to emerging growth companies will make our Class A common stock less attractive to investors and may make it more difficult to compare our performance with other public companies.
Our ability to use our deferred tax assets to offset future taxable income may be subject to limitations that could subject our business to higher tax liability.
We may be limited in the portion of net operating loss carryforwards that we can use in the future to offset taxable income for U.S. federal and state income tax purposes. If not utilized, ourOur net operating loss carryforwards (NOLs)("NOLs") will expire, if unused, beginning in 2022 and 2018,2028, respectively. A lack of future taxable income would adversely affect our ability to utilize these NOLs. In addition, under Section 382 of the Internal Revenue Code of 1986, as amended (the Code)"Code"), a corporation that undergoes an “ownership change” is subject to limitations on its ability to utilize its NOLs to offset future taxable income.

Changes in our stock ownership as well as other changes that may be outside of our control could result in ownership changes under Section 382 of the Code, which could cause our NOLs to be subject to certain limitations. Our NOLs may also be impaired under similar provisions of state law. Our deferred tax assets, which are currently fully reserved with a valuation allowance, may expire unutilized or underutilized, which could prevent us from offsetting future taxable income.

Risks Relating to Our Liquidity
We must maintain customer confidence in our liquidity and long-term business prospects in order to grow our business.
Currently, we are the only provider able to fully support and maintain our Energy Servers. If potential customers believe we do not have sufficient capital or liquidity to operate our business over the long-term or that we will be unable to maintain their Energy Servers and provide satisfactory support, customers may be less likely to purchase or lease our products, particularly in light of the significant financial commitment required. In addition, financing sources may be unwilling to provide financing on reasonable terms. Similarly, suppliers, financing partners, and other third parties may be less likely to invest time and resources in developing business relationships with us if they have concerns about the success of our business.
Accordingly, in order to grow our business, we must maintain confidence in our liquidity and long-term business prospects among customers, suppliers, financing partners, and other parties. This may be particularly complicated by factors such as:
our limited operating history at a large scale;
our lack of profitability;
unfamiliarity with or uncertainty about our Energy Servers and the overall perception of the distributed generation market;
prices for electricity or natural gas in particular markets;
competition from alternate sources of energy;
warranty or unanticipated service issues we may experience;
the environmental consciousness and perceived value of environmental programs to our customers;
the size of our expansion plans in comparison to our existing capital base and the scope and history of operations;
the availability and amount of tax incentives, credits, subsidies or other incentive programs; and
the other factors set forth in this “Risk Factors” section.
Several of these factors are largely outside our control, and any negative perceptions about our liquidity or long-term business prospects, even if unfounded, would likely harm our business.
Our substantial indebtedness, and restrictions imposed by the agreements governing our, and our PPA Entities’, outstanding indebtedness, may limit our financial and operating activities and may adversely affect our ability to incur additional debt to fund future needs.
As of June 30, 2018,March 31, 2019, we and our subsidiaries had approximately $960.1$741.1 million of total consolidated indebtedness, of which an aggregate of $607.4$401.3 million represented indebtedness that is recourse to us. Of this amount, $254.1$741.1 million debt, $35.1 million represented debt under our 8%5% Notes, $4.1$2.8 million represented operating debt, $352.8$339.8 million represented debt of our PPA Entities, $254.1$267.3 million represented debt under our 6% Notes and $95.1$96.1 million represented debt under our 10% Notes. Our substantialThe agreements governing our and our PPA Entities’ outstanding indebtedness contain, and any new indebtedness could:other future debt agreements may contain, covenants imposing operating and financial restrictions on our business that limit our flexibility including, among other things, to:
borrow money;
pay dividends or make other distributions;
incur liens;
make asset dispositions;
make loans or investments;

issue or sell share capital of our subsidiaries;
issue guaranties;
enter into transactions with affiliates;
merge, consolidate or sell, lease or transfer all or substantially all of our assets;
require us to dedicate a substantial portion of cash flow from operations to the payment of principal and interest on indebtedness, thereby reducing the funds available for other purposes such as working capital and capital expenditures;
make it more difficult for us to satisfy and comply with our obligations with respect to our indebtedness;
subject us to increased sensitivity to interest rate increases;
make us more vulnerable to economic downturns, adverse industry conditions, or catastrophic external events;
limit our ability to withstand competitive pressures;
limit our ability to invest in new business subsidiaries that are not PPA Entity-relatedEntity-related;
reduce our flexibility in planning for or responding to changing business, industry, and economic conditions; and/or
place us at a competitive disadvantage to competitors that have relatively less debt than we have.
Our debt agreements and our PPA Entities’ debt agreements require the maintenance of financial ratios or the satisfaction of financial tests such as debt service coverage ratios and consolidated leverage ratios. Our and our PPA Entities’ ability to meet these financial ratios and tests may be affected by events beyond our control and, as a result, we cannot assure you that we will be able to meet these ratios and tests. Upon the occurrence of events such as a change in control of our company, significant asset sales or mergers or similar transactions, the liquidation or dissolution of our company or the cessation of our stock exchange listing, holders of our 6% Notes have we.the right to cause us to repurchase for cash any or all of such outstanding notes at a repurchase price in cash equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon. We cannot provide assurance that we would have sufficient liquidity to repurchase such notes. Furthermore, our financing and debt agreements, such as our 6% Notes and our 10% Notes, contain events of default. If an event of default were to occur, the trustee or the lenders could, among other things, terminate their commitments and declare outstanding amounts due and payable and our cash may become restricted. We cannot provide assurance that we would have sufficient liquidity to repay or refinance our indebtedness if such amounts were accelerated upon an event of default. Borrowings under other debt instruments that contain cross-acceleration or cross-default provisions may, as a result, be accelerated and become due and payable as a consequence. We may be unable to pay these debts in such circumstances. If we were unable to repay those amounts, lenders could proceed against the collateral granted to them to secure repayment of those amounts. We cannot assure you that the collateral will be sufficient to repay in full those amounts. We cannot provide assurance that the operating and financial restrictions and covenants in these agreements will not adversely affect our ability to finance our future operations or capital needs, or our ability to engage in other business activities that may be in our interest or our ability to react to adverse market developments.
If our PPA Entities default on their obligations under non-recourse financing agreements, we may decide to make payments to prevent such PPA Entities’ creditors from foreclosing on the relevant collateral, as such a foreclosure would result in our losing our ownership interest in the PPA Entity or in some or all of its assets, or a material part of our assets, as the case may be. To satisfy these obligations, we may be required to use amounts distributed by our other PPA Entities as well as other sources of available cash, thereby reducing the cash available to develop our projects and to our operations. The loss of a material part of our assets or our ownership interest in one or more of our PPA Entities or some or all of their assets, or any use of our resources to support our obligations or the obligations of our PPA Entities, could have a material adverse effect on our business, our financial condition, and our results of operations.
As of March 31, 2019, we and our subsidiaries had approximately $741.1 million of total consolidated indebtedness, including $37.5 million in short-term debt and $703.6 million in long-term debt. In addition, our 10% Notes contain restrictions on our ability to issue additional debt and both the 6% Notes and 10% Notes limit our ability to provide collateral for any additional debt. Given our current level of indebtedness, the restrictions on additional indebtedness contained in the 10% Notes and the fact that most of our assets serve as collateral to secure existing debt, it may be difficult for us to secure additional debt financing at an attractive cost, which may in turn impact our ability to expand our operations and our product development activities and to remain competitive in the market.
In addition, our substantial level of indebtedness could limit our ability to obtain required additional financing on acceptable terms or at all for working capital, capital expenditures, and general corporate purposes. Any of these risks could impact our ability to fund our operations or limit our ability to expand our business, which could have a material adverse effect

on our business, our financial condition, our liquidity, and our results of operations. Our liquidity needs could vary significantly and may be affected by general economic conditions, industry trends, performance, and many other factors not within our control.
We may not be able to generate sufficient cash to meet our debt service obligations.
Our ability to generate sufficient cash to make scheduled payments on our debt obligations will depend on our future financial performance, which will be affected by a range of economic, competitive, and business factors, many of which are outside of our control.
In addition, we conduct a significant volume of our operations through, and receive equity allocations from, our PPA Entities, which contribute to our cash flow. These PPA Entities are separate and distinct legal entities, do not guarantee our debt obligations, and will have no obligation, contingent or otherwise, to pay amounts due under our debt obligations or to make any funds available to pay those amounts, whether by dividend, distribution, loan, or other payments. Distributions by the PPA Entities to us are precluded under these arrangements if there is an event of default or if financial covenants, such as maintenance of applicable debt service coverage ratios, are not met even if there is not otherwise an event of default. Furthermore, under the terms of our equity financing arrangements for PPA Company II, PPA Company IIIa and PPA Company IIIb, substantially all of the cash flows generated from these PPA Entities in excess of debt service obligations are distributed to Equity Investors until the investors achieve a targeted internal rate of return or until a fixed date in the future ("Flip Date"), which is expected to be after a period of five or more years, (the flip date) after which time we will receive substantially all of the remaining income (loss), tax, and tax allocation attributable to the long-term customer payments and other incentives. In the case of PPA Company IV and PPA Company V, Equity Investors receive 90% of all cash flows generated in excess of its debt service obligations and other expenses for the duration of the applicable PPA Entity without any flip dateFlip Date or other time- or return-based adjustment. Moreover, even after the occurrence of the flip dateFlip Date for the PPA Entities, we do not anticipate distributions to be material enough independently to support our ongoing cash needs, and, therefore, we will still need to generate significant cash from our product sales. Therefore, itIt is possible that the PPA Entities may not contribute significant cash to us even if we are in compliance with the financial covenants under the project debt incurred by the PPA Entities.
Future borrowings by our PPA Entities may contain restrictions or prohibitions on the payment of dividends to us. The ability of our PPA Entities to make such payments to us may be subject to applicable laws including surplus, solvency, and other limits imposed on the ability of companies to pay dividends.
If we do not generate sufficient cash to satisfy our debt obligations, including interest payments, or if we are unable to satisfy the requirement for the payment of principal at maturity or other payments that may be required from time to time under the terms of our debt instruments, we may have to undertake alternative financing plans such as refinancing or restructuring our debt, selling assets, reducing or delaying capital investments, or seeking to raise additional capital. We cannot provide assurance that any refinancing would be possible, that any assets could be sold, or, if sold, of the timing of the sales and the amount of proceeds realized from those sales, that additional financing could be obtained on acceptable terms, if at all, or that additional financing would be permitted under the terms of our various debt instruments then in effect. Furthermore, the ability to refinance indebtedness would depend upon the condition of the finance and credit markets at the time which have in the past been, and may in the future be, volatile. Our inability to generate sufficient cash to satisfy our debt obligations or to refinance our obligations on commercially reasonable terms or on a timely basis would have an adverse effect on our business, our results of operations and our financial condition.

We may not be able to secure additional debt financing.
As of June 30, 2018, we and our subsidiaries had approximately $960.1 million of total consolidated indebtedness, including $30.0 million in short-term debt and $930.1 million in long-term debt. In addition, our 10% Notes contain restrictions on our ability to issue additional debt and both the 6% Notes and 10% Notes limit our ability to provide collateral for any additional debt. Given our current level of indebtedness, the restrictions on additional indebtedness contained in the 10% Notes and the fact that most of our assets serve as collateral to secure existing debt, it may be difficult for us to secure additional debt financing at an attractive cost, which may in turn impact our ability to expand our operations and our product development activities and to remain competitive in the market.
Under some circumstances, we may be required to or elect to make additional payments to our PPA Entities or the Power Purchase Agreement Program Equity Investors.
Our six PPA Entities are structured in a manner such that other than the amount of any equity investment we have made, we do not have any further primary liability for the debts or other obligations of the PPA Entities. However, we are required to guarantee the obligations of our wholly-owned subsidiary which invests alongside other investors in the PPA Entities. These obligations typically include the capital contribution obligations of such subsidiary to the PPA Entity as well as the representations and warranties made by and indemnification obligations of such subsidiary to Equity Investors in the applicable PPA Entity. As a result, we may be obligated to make payments on behalf of our wholly-owned subsidiary to Equity Investors in the PPA Entities in the event of a breach of these representations, warranties or covenants.
All of our PPA Entities that operate Energy Servers for end customers have significant restrictions on their ability to incur increased operating costs, or could face events of default under debt or other investment agreements if end customers are not able to meet their payment obligations under PPAs or if Energy Servers are not deployed in accordance with the project’s schedule. For example, under PPA Company IIIa’s credit agreement, on or before February 19, 2019 PPA Company IIIa iswas obligated to offer its lenders an insurance policy or performance bond the cost of which is not expected to be material, to mitigate the risk should we will fail to perform our obligations under our operation and maintenance obligations to PPA Company IIIa. Upon receipt of such an offer, the lenders may

elect to require PPA Company IIIa to obtain such insurance policy or performance bond, at PPA Company IIIa’s expense, or elect to require PPA Company IIIa to prepay all remaining amounts owed under PPA Company IIIa’s project debt. PPA Company IIIa has offered its lenders such an insurance policy and is awaiting the lenders’ decision. If our PPA Entities experience unexpected, increased costs such as insurance costs, interest expense or taxes or as a result of the acceleration of repayment of outstanding indebtedness, or if end customers are unable or unwilling to continue to purchase power under their PPAs, there could be insufficient cash generated from the project to meet the debt service obligations of the PPA Entity or to meet any targeted rates of return of Equity Investors. If this werea PPA Entity fails to occur,make required debt service payments, this could constitute an event of default and entitle the lender to foreclose on the collateral securing the debt or could trigger other payment obligations of the PPA Entity. To avoid this, we could choose to contribute additional capital to the applicable PPA Entity to enable such PPA Entity to make additional payments to avoid an event of default, which could adversely affect our business or our financial condition. Additionally, under PPA Company II’s credit agreement, PPA Company II is obligated to offer to repay all outstanding debt in the event that we obtain an investment grade credit rating unless we provide a guarantee of the debt obligations of the PPA Company II. Upon receipt of such offer, the lenders may elect to require PPA Company II to prepay all remaining amounts owed under PPA Company II’s project debt. Under PPA Company IV’s note purchase agreement, PPA Company IV is obligated to offer to repay all outstanding debt in the event that at any time we fail to own (directly or indirectly) at least 50.1% of the equity interest of PPA Company IV not owned by the Equity Investor(s). Upon receipt of such offer, the lenders may waive that obligation or elect to require PPA Company IV to prepay all remaining amounts owed under PPA Company IV’s project debt.
Restrictions imposed by the agreements governing The obligations under PPA Company II and IV have not been triggered as of our and our PPA Entities’ outstanding indebtedness contain covenants that significantly limit our actions.
The agreements governing our outstanding indebtedness contain, and our other future debt agreements may contain, covenants imposing operating and financial restrictions on our business that limit our flexibility including, among other things, to:
borrow money;
pay dividends or make other distributions;
incur liens;
make asset dispositions;
make loans or investments;
issue or sell share capital of our subsidiaries;
issue guarantees;
enter into transactions with affiliates; and
merge, consolidate or sell, lease or transfer all or substantially all of our assets.March 31, 2019.

Risks Relating to Our debt agreements and our PPA Entities’ debt agreements require the maintenance of financial ratios or the satisfaction of financial tests such as debt service coverage ratios and consolidated leverage ratios. Our and our PPA Entities’ ability to meet these financial ratios and tests may be affected by events beyond our control and, as a result, we cannot assure you that we will be able to meet these ratios and tests. Upon the occurrence of events such as a change in control of our company, significant asset sales or mergers or similar transactions, the liquidation or dissolution of our company or the cessation of our stock exchange listing, holders of our 6% Notes have the right to cause us to repurchase for cash any or all of such outstanding notes at a repurchase price in cash equal to 100% of the principal amount thereof, plus accrued and unpaid interest thereon. We cannot provide assurance that we would have sufficient liquidity to repurchase the notes. Furthermore, our financing and debt agreements, such as our 6% Notes and our 10% Notes, contain events of default. If an event of default were to occur, the trustee or the lenders could, among other things, terminate their commitments and declare outstanding amounts due and payable and our cash may become restricted. We cannot provide assurance that we would have sufficient liquidity to repay or refinance our indebtedness if such amounts were accelerated upon an event of default. Borrowings under other debt instruments that contain cross-acceleration or cross-default provisions may, as a result, be accelerated and become due and payable as a consequence. We may be unable to pay these debts in such circumstances. If we were unable to repay those amounts, lenders could proceed against the collateral granted to them to secure repayment of those amounts. We cannot assure you that the collateral will be sufficient to repay in full those amounts. We cannot assure you that the operating and financial restrictions and covenants in these agreements will not adversely affect our ability to finance our future operations or capital needs, or our ability to engage in other business activities that may be in our interest or our ability react to adverse market developments.
If our PPA Entities default on their obligations under non-recourse financing agreements, we may decide to make payments to prevent such PPA Entities’ creditors from foreclosing on the relevant collateral, as such a foreclosure would result in our losing our ownership interest in the PPA Entity or in some or all of its assets, or a material part of our assets, as the case may be. To satisfy these obligations, we may be required to use amounts distributed by our other PPA Entities as well as other sources of available cash, reducing the cash available to develop our projects and to our operations. The loss of a material part of our assets or our ownership interest in one or more of our PPA Entities or some or all of their assets, or any use of our resources to support our obligations or the obligations of our PPA Entities, could have a material adverse effect on our business, our financial condition and our results of operations.Operations
We may have conflicts of interest with our PPA Entities.
In each of our PPA Entity,Entities, we act as the managing member and are responsible for the day-to-day administration of the project. However, we are also a major service provider for each PPA Entity in its capacity as the operator of the Energy Servers under an operations and maintenance agreement. Because we are both the administrator and the manager of theour PPA Entities, as well as a major service provider, we face a potential conflict of interest in that we may be obligated to enforce contractual rights that a PPA Entity has against us in our capacity as a service provider. By way of example, the PPA Entity may have a right to payment from us under a warranty provided under the applicable operations and maintenance agreement, and we may be financially motivated to avoid or delay this liability by failing to promptly enforce this right on behalf of the PPA Entity. While we do not believe that we had any conflicts of interest with our PPA Entities as of June 30, 2018,March 31, 2019, conflicts of interest may arise in the future which cannot be foreseen at this time. In the event that prospective future Equity Investors and debt financing partners perceive there to exist any such conflicts, it could harm our ability to procure financing for our PPA Entities in the future, which could have a material adverse effect on our business.
If we are unable to attract and retain key employees and hire qualified management, technical, engineering, and sales personnel, our ability to compete and successfully grow our business could be harmed.
We believe that our success and our ability to reach our strategic objectives are highly dependent on the contributions of our key management, technical, engineering, and sales personnel. The loss of the services of any of our key employees could disrupt our operations, delay the development and introduction of our products and services and negatively impact our business, prospects, and operating results. In particular, we are highly dependent on the services of Dr. Sridhar, our Chairman and President and Chief Executive Officer, and other key employees. None of our key employees is bound by an employment agreement for any specific term. We cannot assure you that we will be able to successfully attract and retain senior leadership necessary to grow our business. Furthermore, there is increasing competition for talented individuals in our field, and competition for qualified personnel is especially intense in the San Francisco Bay Area where our principal offices are located. Our failure to attract and retain our executive officers and other key management, technical, engineering, and sales personnel could adversely impact our business, our prospects, our financial condition, and our operating results. In addition, we do not have “key person” life insurance policies covering any of our officers or other key employees.
A breach or failure of our networks or computer or data management systems could damage our operations and our reputation.
Our business is dependent on the security and efficacy of our networks and computer and data management systems. For example, all of our Energy Servers are connected to and controlled and monitored by our centralized remote monitoring service, and we rely on our internal computer networks for many of the systems we use to operate our business generally. Although we take protective measures and endeavor to modify them as circumstances warrant, the security of our infrastructure, including the network that connects our Energy Servers to our remote monitoring service, may be vulnerable to breaches, unauthorized access, misuse, computer viruses, or other malicious code and cyber-attacks that could have a material adverse impact on our

business and our Energy Servers in the field. A breach or failure of our networks or computer or data management systems due to intentional actions such as cyber-attacks, negligence, or other reasons could seriously disrupt our operations or could affect our ability to control or to assess the performance in the field of our Energy Servers and could result in disruption to our business and potentially legal liability.In addition, if certain of our IT systems failed, our production line might be affected, which could impact our business and operating results. These events, in addition to impacting our financial results, could result in significant costs or reputational consequences.
Our headquarters and other facilities are located in an active earthquake zone, and an earthquake or other types of natural disasters or resource shortages could disrupt and harm our results of operations.
We conduct a majority of our operations in the San Francisco Bay area in an active earthquake zone, and certain of our facilities are located within known flood plains. The occurrence of a natural disaster such as an earthquake, drought, flood, localized extended outages of critical utilities or transportation systems, or any critical resource shortages could cause a significant interruption in our business, damage or destroy our facilities, our manufacturing equipment, or our inventory, and cause us to incur significant costs, any of which could harm our business, our financial condition, and our results of operations. The insurance we maintain against fires, earthquakes and other natural disasters may not be adequate to cover our losses in any particular case.
Expanding operations internationally could expose us to risks.
Although we currently primarily operate in the United States, we will seek to expand our business internationally. We currently have operations in Japan, China, India, and the Republic of Korea, collectively our Asia Pacific region. Managing any international expansion will require additional resources and controls including additional manufacturing and assembly facilities. Any expansion internationally could subject our business to risks associated with international operations, including:
conformity with applicable business customs, including translation into foreign languages and associated expenses;
lack of availability of government incentives and subsidies;
challenges in arranging, and availability of, financing for our customers;
potential changes to our established business model;
cost of alternative power sources, which could be meaningfully lower outside the United States;
availability and cost of natural gas;
difficulties in staffing and managing foreign operations in an environment of diverse culture, laws, and customers, and the increased travel, infrastructure, and legal and compliance costs associated with international operations;
installation challenges which we have not encountered before which may require the development of a unique model for each country;
compliance with multiple, potentially conflicting and changing governmental laws, regulations, and permitting processes including environmental, banking, employment, tax, privacy, and data protection laws and regulations such as the EU Data Privacy Directive;
compliance with U.S. and foreign anti-bribery laws including the Foreign Corrupt Practices Act and the U.K. Anti-Bribery Act;
difficulties in collecting payments in foreign currencies and associated foreign currency exposure;
restrictions on repatriation of earnings;
compliance with potentially conflicting and changing laws of taxing jurisdictions where we conduct business and compliance with applicable U.S. tax laws as they relate to international operations, the complexity and adverse consequences of such tax laws, and potentially adverse tax consequences due to changes in such tax laws; and
regional economic and political conditions.
As a result of these risks, any potential future international expansion efforts that we may undertake may not be successful.

We are an “emerging growth company”company,” and we cannot be certain if the reduced disclosure requirements applicable to emerging growth companies will make our Class A common stock less attractive to investors and may make it more difficult to compare our performance with other public companies.
We are an “emergingemerging growth company ("EGC") as defined in the JOBSU.S. legislation Jumpstart Our Business Startups Act of 2012 (the "JOBS Act"), and we intend to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies,”EGC, including not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. We may take advantage of these exemptions for so long as we are an “emerging growth company,”EGC, which could be until December 31, 2023, the last day of the fiscal year following the fifth anniversary of our initial public offering.IPO. We cannot predict if investors will find our Class A common stock less attractive because we will rely on these exemptions. If some investors find our Class A common stock less attractive as a result, there may be a less active trading market for our Class A common stock, and our stock price may be more volatile.
As an “emerging growth company”, we have electedAn EGC may elect to useprovide financial statements in conformance with the extendedU.S. GAAP requirement for transition period for complyingperiods to comply with new or revised accounting standards understandards. With our not making this election, Section 102(b)(2) of the JOBS Act that allows us to delay theour adoption of new or revised accounting standards that have different effective dates for public and private companies until those standards apply to private

The stock price of our Class A common stock has been and may continue to be volatile, and you could lose all or part of your investment.volatile.
The market price of our Class A common stock has been and may continue to be volatile. In addition to factors discussed in this Quarterly Report on Form 10-Q, the market price of our Class A common stock may fluctuate significantly in response to numerous factors, many of which are beyond our control, including:
overall performance of the equity markets;
actual or anticipated fluctuations in our revenue and other operating results;
changes in the financial projections we may provide to the public or our failure to meet these projections;
failure of securities analysts to initiate or maintain coverage of us, changes in financial estimates by any securities analysts who follow our company or our failure to meet these estimates or the expectations of investors;
recruitment or departure of key personnel;
the economy as a whole and market conditions in our industry;
new laws, regulations, or subsidies, or credits or new interpretations of them applicable to our business;
negative publicity related to problems in our manufacturing or the real or perceived quality of our products;
rumors and market speculation involving us or other companies in our industry;
announcements by us or our competitors of significant technical innovations, acquisitions, strategic partnerships, or capital commitments;
lawsuits threatened or filed against us;
other events or factors including those resulting from war, incidents of terrorism or responses to these events;
the expiration of contractual lock-up or market standoff agreements; and
sales or anticipated sales of shares of our Class A common stock by us or our stockholders.
In addition, the stock markets have experienced extreme price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many companies. Stock prices of many companies have fluctuated in a manner unrelated or disproportionate to the operating performance of those companies. In the past, stockholders have instituted securities class action litigation following periods of market volatility. If we were to become involved in securities litigation, it could subject us to substantial costs, divert resources and the attention of management from our business, and adversely affect our business.

Sales of substantial amounts of our Class A common stock in the public markets, or the perception that they might occur, could cause the market price of our Class A common stock to decline.
The market price of our Class A common stock could decline as a result of sales of a large number of shares of our Class A common stock in the public market.market as and when our Class B common stock converts to Class A common stock. The perception that these sales might occur may also cause the market price of our common stock to decline. We had a total of 10,570,84159,407,578 shares of our Class A common stock and 53,806,485 shares of our Class B common stock outstanding as of June 30, 2018. In addition, 20,700,000March 31, 2019. The lock up for our Class B shares ofexpired on January 21, 2019 and these shares are now freely tradeable once converted into Class A common stock sold in our in July 2018 IPO are freely tradable,shares, except for any shares purchased by our “affiliates” as defined in Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”("Securities Act").
With respect to ourFurther, as of March 31, 2019, we had an aggregate of $296.2 million in convertible debt under which the outstanding shares of common stock not sold inprincipal and interest may be converted, at the initial public offering, subject to certain exceptions, we, all of our directors and executive officers and alloption of the holders, into an aggregate of our common stock and securities exercisable for or convertible into our common stock outstanding immediately prior to our IPO, are subject to market stand-off agreements with us or have entered into lock-up agreements with the underwriters of our IPO under which they have agreed, subject to specific exceptions, not to sell, directly or indirectly, any26.3 million shares of Class B common stock without the permission of our IPO underwriters, for a period of 180 days from July 24, 2018, the date of the Prospectus used in connection with our IPO; provided that if such restricted period ends during a trading blackout period, the restricted period will end one business day following the date that we announce our earnings results for the previous quarter. When the lock-up period expires, we and our security holders subject to a lock-up agreement or market standoff agreement will be able to sell shares in the public market. In addition, the underwriters from our IPO may, in their sole discretion, release all or some portion of the shares subject to lock-up agreements prior to the expiration of the lock-up period. Sales of a substantial number of such shares upon expiration of the lock-up and market stand-off agreements, or the perception that such sales may occur or early release of these agreements, could cause our market price to fall or make it more difficult for you to sell yourstock. Upon conversion into Class A common stock, at a time and price that you deem appropriate.

these shares are freely tradable, except to the extent these shares are held by our “affiliates” as defined in Rule 144 under the Securities Act.
In addition, as of June 30, 2018,March 31, 2019, we had options and RSUs outstanding that, if fully exercised or settled, would result in the issuance of 3,107,10123,140,981 shares of Class B common stock. Subsequent to June 30, 2018, we also issued restricted stock units that may be settled for 13,747,182 shares of our Class B common stock. We have filed a registration statement on Form S-8 to register shares reserved for future issuance under our equity compensation plans. Subject to the satisfaction of applicable vesting requirements and expiration of the market standoff agreements and lock-up agreements referred to above, the shares issued upon exercise of outstanding stock options or settlement of outstanding RSUs will be available for immediate resale in the United States in the open market.
Moreover, certain holders of our common stock have rights, subject to some conditions, to require us to file registration statements for the public resale of such shares or to include such shares in registration statements that we may file for us or other stockholders.
The dual class structure of our common stock and the voting agreements among certain stockholders have the effect of concentrating voting control of our Company with KR Sridhar, our Chairman and Chief Executive Officer, and Chairman, and also with those stockholders who held our capital stock prior to the completion of our initial public offeringIPO including our directors, executive officers and significant stockholders, which limits or precludes your ability to influence corporate matters including the election of directors and the approval of any change of control transaction, and may adversely affect the trading price of our Class A common stock.
Our Class B common stock has ten votes per share, and our Class A common stock has one vote per share. As of June 30, 2018March 31, 2019 and after giving effect to the voting agreements between KR Sridhar, our Chairman and Chief Executive Officer, and Chairman, and certain holders of Class B common stock, our directors, executive officers, significant stockholders of our common stock, and their respective affiliates collectively held a substantial majority of the voting power of our capital stock. Because of the ten-to-one voting ratio between our Class B and Class A common stock, the holders of our Class B common stock collectively will continue to control a majority of the combined voting power of our common stock and therefore are able to control all matters submitted to our stockholders for approval until the earliest to occur of (i) immediately prior to the close of business on July 27, 2023, (ii) immediately prior to the close of business on the date on which the outstanding shares of Class B common stock represent less than five percent (5%) of the aggregate number of shares of Class A common stock and Class B common stock then outstanding, (iii) the date and time or the occurrence of an event specified in a written conversion election delivered by KR Sridhar to our Secretary or Chairman of the Board to so convert all shares of Class B common stock, or (iv) immediately following the date of the death of KR Sridhar. This concentrated control limits or precludes Class A stockholders’ ability to influence corporate matters while the dual class structure remains in effect, including the election of directors, amendments of our organizational documents, and any merger, consolidation, sale of all or substantially all of our assets, or other major corporate transaction requiring stockholder approval. In addition, this may prevent or discourage unsolicited acquisition proposals or offers for our capital stock that Class A stockholders may feel are in their best interest as one of our stockholders.
Future transfers by holders of Class B common stock will generally result in those shares converting to Class A common stock, subject to limited exceptions such as certain transfers effected for estate planning purposes. The conversion of Class B common stock to Class A common stock will have the effect, over time, of increasing the relative voting power of those remaining holders of Class B common stock who retain their shares in the long-term.
The conversion of the 6% Convertible Promissory Note could result in a significant stockholder with substantial voting control.
The holders of the 6% Convertible Promissory Notes have the options to convert the outstanding principal and interest under the 6% Convertible Promissory Note to Class B common stock at conversion price of $11.25 at any time after the IPO

and prior to maturity of the 6% Convertible Promissory Note in December 2020. As of March 31, 2019, an aggregate of 21,321,100 shares of Class B common stock is issuable to the Canada Pension Plan Investment Board (“CPPIB”) upon the conversion of the outstanding principal and interest under the 6% Convertible Promissory Note. This, along with 312,575 shares of Class B common stock CPPIB which CPPIB acquired from the exercise of a warrant at IPO, would result in CPPIB having approximately 25.13% of the total voting power with respect to all shares of our Class A and Class B common stock, voting as a single class and would provide CPPIB significant influence over matters presented to the stockholders for approval and may result in voting decisions by CPPIB which are not in the best interests of our stockholders generally.
The dual class structure of our common stock may adversely affect the trading market for our Class A common stock.
S&P Dow Jones and FTSE Russell have recently announced changes to their eligibility criteria for inclusion of shares of public companies on certain indices, including the S&P 500, namely, to exclude companies with multiple classes of shares of common stock from being added to such indices. In addition, several shareholder advisory firms have announced their opposition to the use of multiple class structures. As a result, the dual class structure of our common stock may prevent the inclusion of our Class A common stock in such indices and may cause shareholder advisory firms to publish negative commentary about our corporate governance practices or otherwise seek to cause us to change our capital structure. Any such exclusion from indices could result in a less active trading market for our Class A common stock. Any actions or publications by shareholder advisory firms critical of our corporate governance practices or capital structure could also adversely affect the value of our Class A common stock.
If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, the market price of our Class A common stock and trading volume could decline.
The market price for our Class A common stock depends in part on the research and reports that securities or industry analysts publish about us or our business. If few securities analysts commence coverage of us or if industry analysts cease coverage of us, the trading price for our Class A common stock would be negatively affected. IfIn addition, if one or more of the analysts who cover us downgrade our Class A common stock or publish inaccurate or unfavorable research about our business, our Class A common stock price would likely decline. If one or more of these analysts cease coverage of us or fail to publish reports on

us regularly, demand for our Class A common stock could decrease, which might cause our Class A common stock price and trading volume to decline.
We do not intend to pay dividends for the foreseeable future.
We have never declared or paid any cash dividends on our capital stock and do not intend to pay any cash dividends in the foreseeable future. We anticipate that we will retain all of our future earnings for use in the development of our business and for general corporate purposes. Any determination to pay dividends in the future will be at the discretion of our board of directors. Accordingly, investors must rely on sales of their Class A common stock after price appreciation, which may never occur, as the only way to realize any future gains on their investments.
Provisions in our charter documents and under Delaware law could make an acquisition of our company more difficult, may limit attempts by our stockholders to replace or remove our current management, may limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, or employees, and may limit the market price of our Class A common stock.
Provisions in our restated certificate of incorporation and amended and restated bylaws may have the effect of delaying or preventing a change of control or changes in our management. Our restated certificate of incorporation and amended and restated bylaws include provisions that:
provide that our board of directors will be classified into three classes of directors with staggered three year terms;
permit the board of directors to establish the number of directors and fill any vacancies and newly created directorships;
require super-majority voting to amend some provisions in our restated certificate of incorporation and amended and restated bylaws;
authorize the issuance of “blank check” preferred stock that our board of directors could use to implement a stockholder rights plan;
provide that only the chairman of our board of directors, our chief executive officer, or a majority of our board of directors will be authorized to call a special meeting of stockholders;
prohibit stockholder action by written consent, which thereby requires all stockholder actions be taken at a meeting of our stockholders;
provide for
a dual class common stock structure in which holders of our Class B common stock may have the ability to control the outcome of matters requiring stockholder approval even if they own significantly less than a majority of the outstanding shares of our common stock, including the election of directors and significant corporate transactions such as a merger or other sale of our company or substantially all of its assets;
provide that the board of directors is expressly authorized to make, alter, or repeal our bylaws; and
establish advance notice requirements for nominations for election to our board of directors or for proposing matters that can be acted upon by stockholders at annual stockholder meetings.
In addition, our restated certificate of incorporation and our amended and restated bylaws provide that the Court of Chancery of the State of Delaware will be the exclusive forum for: any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claim against us arising pursuant to the Delaware General Corporation Law, our restated certificate of incorporation or our amended and restated bylaws; or any action asserting a claim against us that is governed by the internal affairs doctrine. Our restated certificate of incorporation and our amended and restated bylaws will also provide that unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States of America shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933, as amended.Act. These choice of forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or any of our directors, officers, or other employees, which thereby may discourage lawsuits with respect to such claims. Alternatively, if a court were to find the choice of forum provision contained in our restated certificate of incorporation and our amended and restated bylaws to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business, our operating results, and our financial condition.
On December 19, 2018, the Delaware Chancery Court issued an opinion that invalidated provisions in a Delaware corporation’s certificate of incorporation or bylaws that purport to limit to federal court the forum in which a stockholder could bring a claim under the Securities Act, which creates some uncertainty about the enforceability of exclusive forum provisions generally. If a court were to find the choice of forum provision contained in our amended and restated certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business and financial condition.
Moreover, Section 203 of the Delaware General Corporation Law may discourage, delay, or prevent a change in control of our company. Section 203 imposes certain restrictions on mergers, business combinations, and other transactions between us and holders of 15% or more of our common stock.


ITEM 2 - UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

Unregistered Sales of Equity SecuritiesNone.
From April 1, 2018 through June 30, 2018, we granted options to purchase an aggregate of 313,909 shares of Class B common stock under our 2012 Plan, with a per share exercise price of $30.96 and we issued 145,856 shares of Class B common stock upon exercise of stock options under our 2012 Plan. These shares were issued pursuant to benefit plans and contracts related to compensation in reliance upon the exemption from registration requirements of Rule 701 of the Securities Act. The recipients of the securities in each of these transactions represented their intentions to acquire the securities for investment only and not with a view to or for sale in connection with any distribution thereof, and appropriate legends were placed upon the stock certificates issued in these transactions.
Use of Proceeds
In July 2018, we closed our initial public offering in which we sold 20,700,000 shares of Class A common stock at a price to the public of $15.00 per share including shares sold in connection with the exercise of the underwriters’ option to purchase additional shares. The offer and sale of all of the shares in the IPO were registered under the Securities Act pursuant to a registration statement on Form S-1 (File No. 333-225571), which was declared effective by the SEC on July 24, 2018. We raised aggregate net proceeds of $284.3 million from the IPO after underwriting discounts and commissions and payments of offering costs. There has been no material change in the planned use of proceeds from our IPO as described in the Prospectus. The managing underwriters of our IPO were J.P. Morgan Securities LLC and Morgan Stanley & Co. LLC. No payments were made by us to directors, officers or persons owning ten percent or more of our common stock or to their associates, or to our affiliates, other than payments in the ordinary course of business to officers for salaries and to non-employee directors pursuant to our director compensation policy.
