Organization/ Description of Business [Abstract]
Description of Business	Note 1—Organization Organization Ener-Core, Inc. (the “Company”, “we”, “us”, “our”), a Delaware corporation, was formed on April 29, 2010 as Inventtech, Inc. On July 1, 2013, we acquired our wholly owned subsidiary, Ener-Core Power, Inc., (formerly Flex Power Generation, Inc.), a Delaware corporation. The stockholders of Ener-Core Power, Inc. are now our stockholders and the management of Ener-Core Power, Inc. is now our management. The acquisition was treated as a “reverse merger” and our financial statements are those of Ener-Core Power, Inc. All equity amounts presented have been retroactively restated to reflect the reverse merger as if it had occurred on November 12, 2012. Effective as of September 3, 2015, we changed our state of incorporation from the State of Nevada to the State of Delaware (the “Reincorporation”), pursuant to a plan of conversion dated September 2, 2015, following approval by our stockholders of the Reincorporation at our 2015 Annual Meeting of Stockholders held on August 28, 2015. As a Delaware corporation following the Reincorporation, we are deemed to be the same continuing entity as the Nevada corporation prior to the Reincorporation, and as such continue to possess all of the rights, privileges and powers and all of the debts, liabilities and obligations of the prior Nevada corporation. Upon effectiveness of the Reincorporation, all of the issued and outstanding shares of common stock of the Nevada corporation automatically converted into issued and outstanding shares of common stock of the Delaware corporation without any action on the part of our stockholders. Concurrent with the Reincorporation, on September 3, 2015 our authorized shares increased to 250,000,000 shares of stock consisting of 200,000,000 authorized shares of common stock and 50,000,000 authorized shares of preferred stock. Reverse Merger We entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Ener-Core Power, Inc. and Flex Merger Acquisition Sub, Inc., a Delaware corporation and our wholly owned subsidiary (“Merger Sub”), pursuant to which the Merger Sub merged with and into Ener-Core Power, Inc., with Ener-Core Power, Inc. as the surviving entity (the “Merger”). Prior to the Merger, we were a public reporting “shell company,” as defined in Rule 12b-2 of the Securities Exchange Act of 1934, as amended. The Merger Agreement was approved by the boards of directors of each of the parties to the Merger Agreement. In April 2013, the pre-merger public shell company effected a 30-for-1 forward split of its common stock. All share amounts have been retroactively restated to reflect the effect of the stock split. As provided in the Contribution Agreement dated November 12, 2012 (the “Contribution Agreement”) by and among FlexEnergy, Inc. (“FlexEnergy”), FlexEnergy Energy Systems, Inc. (“FEES”), and Ener-Core Power, Inc., Ener-Core Power, Inc. was spun-off from FlexEnergy as a separate corporation. As a part of that transaction, Ener-Core Power, Inc. received all assets (including intellectual property) and certain liabilities pertaining to the Power Oxidizer business carved out of FlexEnergy. The owners of FlexEnergy did not distribute ownership of Ener-Core Power, Inc. pro rata. The assets and liabilities were transferred to us and recorded at their historical carrying amounts since the transaction was a transfer of net assets between entities under common control. On July 1, 2013, Ener-Core Power, Inc. completed the Merger with us. Upon completion of the Merger, we immediately became a public company. The Merger was accounted for as a “reverse merger” and recapitalization. As part of the Merger, 2,410,400 shares of outstanding common stock of the pre-merger public shell company were cancelled. This cancellation has been retroactively accounted for as of the inception of Ener-Core Power, Inc. on November 12, 2012. Accordingly, Ener-Core Power, Inc. was deemed to be the accounting acquirer in the transaction and, consequently, the transaction was treated as a recapitalization of Ener-Core Power, Inc. Accordingly, the assets and liabilities and the historical operations that are reflected in the financial statements are those of Ener-Core Power, Inc. and are recorded at the historical cost basis of Ener-Core Power, Inc. Our assets, liabilities and results of operations were de minimis at the time of the Merger. Reverse Stock Split The board of directors of the Company approved a reverse stock split of the Company’s authorized, issued and outstanding shares of common stock, par value $0.0001 per share, as well as the Company’s authorized shares of preferred stock, par value $0.0001 per share, of which no shares are issued and outstanding (together, the “Stock”), at a ratio of 1-for-50 (the “Reverse Stock Split”). The Reverse Stock Split became effective on July 8, 2015 (the “Effective Date”). As a result of the Reverse Stock Split, the authorized preferred stock decreased to 1,000,000 shares and the authorized common stock decreased to 4,000,000 shares. Both the preferred stock and common stock par value remained at $0.0001 per share. The number of authorized shares subsequently increased to 200,000,000 authorized shares of common stock and 50,000,000 authorized shares of preferred stock on September 3, 2015 with the Company’s reincorporation in Delaware, as described above. On the Effective Date, the total number of shares of common stock held by each stockholder of the Company were converted automatically into the number of shares of common stock equal to: (i) the number of issued and outstanding shares of common stock held by each such stockholder immediately prior to the Reverse Stock Split divided by (ii) 50. The Company issued one whole share of the post-Reverse Stock Split common stock to any stockholder who otherwise would have received a fractional share as a result of the Reverse Stock Split, determined at the beneficial owner level by share certificate. As a result, no fractional shares were issued in connection with the Reverse Stock Split and no cash or other consideration will be paid in connection with any fractional shares that would otherwise have resulted from the Reverse Stock Split. The Reverse Stock Split also affected all outstanding options and warrants by dividing each option or warrant outstanding by 50, rounded up to the nearest option or warrant, and multiplying the exercise price by 50 for each option or warrant outstanding. Description of the Business We design, develop, and manufacture products based on proprietary technologies that aim to expand the operating range of gaseous fuel while improving emissions, which technologies we refer to collectively as “Power Oxidation” or “Power Oxidizer”. Our products aim to expand power generation into previously uneconomical markets while, at the same time, reduce gaseous emissions from industrial processes that contribute to air pollution and climate change. The Power Oxidizer integrates with a gas turbine and generator to create a Powerstation. Our products, the EC250 and the Ener-Core Powerstation KG2-3G/GO (“KG2”), are complete systems consisting of our designed and patented Power Oxidizer, integrated with a gas turbine and generator. Our Power Oxidizers have been designed to operate on fuels from 100% combustible gas down to concentrations of 5% or less combustible gas content. Our Powerstation products have applications in landfills, distilleries, wastewater treatment plants, as well as numerous industrial processes, and offers our customers two distinct value propositions: the destruction of low quality waste gases with no harmful emissions and the generation of energy from a renewable and low-cost fuel source. We have deployed the EC250 product commercially in landfill applications are currently developing our second commercial product, the KG2 Powerstation, or KG2, which will combine our Power Oxidizer with a two megawatt gas turbine developed by Dresser-Rand a.s., a subsidiary of Dresser-Rand Group Inc. (“Dresser-Rand”). In 2015, we completed system layout and analytic models integrating our Power Oxidizer with the turbine and, to date in 2016, we have constructed a fully operational KG2 unit to be used in final technical tests expected to be completed in the fourth quarter of 2016, after which time we expect that the initial KG2 unit will be sold. We received an order for the first two commercial KG2 units, which we delivered in October 2016. On June 29, 2016, we entered into a Commercial License and Manufacturing Agreement with Dresser-Rand (the “CMLA”), which will become effective upon the successful completion of the technical test and which will transition the KG2 manufacturing to Dresser-Rand. Once effective, each KG2 unit sold will generate for us a non-refundable license fee. Until the test is successfully completed, our existing CLA (as defined below) remains in effect. We sell our EC250 product directly and through distributors in two countries, the United States and Netherlands, and sell the KG2 product directly and through Dresser-Rand’s commercial sales team. Going Concern Our consolidated financial statements are prepared using the accrual method of accounting in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and have been prepared on a going concern basis, which contemplates the realization of assets and settlement of liabilities in the normal course of business. Since our inception, we have made a substantial investment in research and development to develop the Power Oxidizer, have successfully deployed an EC250 field test unit at the U.S. Army base at Fort Benning, Georgia, and installed and commissioned our first commercial unit in the Netherlands in the second quarter of 2014. In November 2014, we signed a Commercial License Agreement with Dresser-Rand (as amended, the “CLA”) to incorporate our Power Oxidizer into Dresser-Rand’s 1.75MW turbine. In August 2015, the CLA became a mutually binding agreement due to the satisfaction of certain binding conditions contained in the CLA. On June 29, 2016 we signed the CMLA. The CMLA becomes binding and will supersede the CLA after the satisfaction of the final technical milestone under the CLA, which we expect to occur in the fourth quarter of 2016. We have sustained recurring net losses and negative cash flows since inception and have not yet established an ongoing source of revenues sufficient to cover our operating costs and allow us to continue as a going concern. Despite capital raises of $2.5 million in December 2015, $3.0 million in April 2016, and $1.25 million in September 2016, we expect to require additional sources of capital to support the Company’s growth initiatives. We must secure additional funding to continue as a going concern and execute our business plan. Management’s plan is to obtain capital sufficient to meet our operating expenses by seeking additional equity and/or debt financing. The cash and cash equivalents balance (excluding restricted cash) on September 30, 2016 and December 31, 2015 was approximately $0.6 million and $2.6 million, respectively. In April 2016, management began taking steps to reduce our operational cash burn through a combination of staff reductions and reductions of outside service providers. We expect to implement additional cost savings through reduced overhead costs later in 2016 as well as reduced non-recurring costs and capital expenditures related to our efforts to develop the 2MW KG2 Powerstation. We expect that the $0.6 million of cash and cash equivalents as of September 30, 2016 and receipts on customer billings will continue to fund our working capital needs, general corporate purposes, and related obligations into the fourth quarter of 2016 at our reduced spending levels. However, we expect to require significantly more cash for working capital and as financial security to support our growth initiatives beginning in the fourth quarter of 2016 and beyond. We will pursue raising additional equity and/or debt financing to fund our operations and product development. If future funds are raised through issuance of stock or debt, these securities could have rights, privileges, or preferences senior to those of our common stock and debt covenants that could impose restrictions on our operations. Any equity or convertible debt financing will likely result in additional dilution to our current stockholders. We cannot make any assurances that any additional financing, including the proposed registered offering, will be completed on a timely basis, on acceptable terms or at all. Our inability to successfully raise capital in a timely manner will adversely impact our ability to continue as a going concern. If our business fails or we are unable to raise capital on a timely basis, our investors may face a complete loss of their investment. The accompanying consolidated financial statements do not give effect to any adjustments that might be necessary if we were unable to meet our obligations or continue operations as a going concern.	Note 1—Description of Business Organization Ener-Core, Inc. (the “Company”, “we”, “us”, “our”), a Delaware corporation, was formed on April 29, 2010 as Inventtech, Inc. On July 1, 2013, we acquired our wholly owned subsidiary, Ener-Core Power, Inc., (formerly Flex Power Generation, Inc.), a Delaware corporation. The stockholders of Ener-Core Power, Inc. are now our stockholders and the management of Ener-Core Power, Inc. is now our management. The acquisition was treated as a “reverse merger” and our financial statements are those of Ener-Core Power, Inc. All equity amounts presented have been retroactively restated to reflect the reverse merger as if it had occurred on November 12, 2012. Effective as of September 3, 2015, we changed our state of incorporation from the State of Nevada to the State of Delaware (the “Reincorporation”), pursuant to a plan of conversion dated September 2, 2015, following approval by our stockholders of the Reincorporation at our 2015 Annual Meeting of Stockholders held on August 28, 2015. As a Delaware corporation following the Reincorporation, we are deemed to be the same continuing entity as the Nevada corporation prior to the Reincorporation, and as such continue to possess all of the rights, privileges and powers and all of the debts, liabilities and obligations of the prior Nevada corporation. Upon effectiveness of the Reincorporation, all of the issued and outstanding shares of common stock of the Nevada corporation automatically converted into issued and outstanding shares of common stock of the Delaware corporation without any action on the part of our stockholders. Concurrent with the Reincorporation, on September 3, 2015 our authorized shares increased to 250,000,000 shares of stock consisting of 200,000,000 authorized shares of common stock and 50,000,000 authorized shares of preferred stock. Reverse Merger We entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Ener-Core Power, Inc. and Flex Merger Acquisition Sub, Inc., a Delaware corporation and our wholly owned subsidiary (“Merger Sub”), pursuant to which the Merger Sub merged with and into Ener-Core Power, Inc., with Ener-Core Power, Inc. as the surviving entity (the “Merger”). Prior to the Merger, we were a public reporting “shell company,” as defined in Rule 12b-2 of the Securities Exchange Act of 1934, as amended. The Merger Agreement was approved by the boards of directors of each of the parties to the Merger Agreement. In April 2013, the pre-merger public shell company effected a 30-for-1 forward split of its common stock. All share amounts have been retroactively restated to reflect the effect of the stock split. As provided in the Contribution Agreement dated November 12, 2012 (the “Contribution Agreement”) by and among FlexEnergy, Inc. (“FlexEnergy”), FlexEnergy Energy Systems, Inc. (“FEES”), and Ener-Core Power, Inc., Ener-Core Power, Inc. was spun-off from FlexEnergy as a separate corporation. As a part of that transaction, Ener-Core Power, Inc. received all assets (including intellectual property) and certain liabilities pertaining to the Power Oxidizer business carved out of FlexEnergy. The owners of FlexEnergy did not distribute ownership of Ener-Core Power, Inc. pro rata. The assets and liabilities were transferred to us and recorded at their historical carrying amounts since the transaction was a transfer of net assets between entities under common control. On July 1, 2013, Ener-Core Power, Inc. completed the Merger with us. Upon completion of the Merger, we, immediately became a public company. The Merger was accounted for as a “reverse merger” and recapitalization. As part of the Merger, 2,410,400 shares of outstanding common stock of the pre-merger public shell company were cancelled. This cancellation has been retroactively accounted for as of the inception of Ener-Core Power, Inc. on November 12, 2012. Accordingly, Ener-Core Power, Inc. was deemed to be the accounting acquirer in the transaction and, consequently, the transaction was treated as a recapitalization of Ener-Core Power, Inc. Accordingly, the assets and liabilities and the historical operations that are reflected in the financial statements are those of Ener-Core Power, Inc. and are recorded at the historical cost basis of Ener-Core Power, Inc. Our assets, liabilities and results of operations were de minimis at the time of the Merger. Reverse Stock Split The board of directors of the Company approved a reverse stock split of the Company’s authorized, issued and outstanding shares of common stock, par value $0.0001 per share, as well as the Company’s authorized shares of preferred stock, par value $0.0001 per share, of which no shares are issued and outstanding (together, the “Stock”), at a ratio of 1-for-50 (the “Reverse Stock Split”). The Reverse Stock Split became effective on July 8, 2015 (the “Effective Date”). As a result of the Reverse Stock Split, the authorized preferred stock decreased to 1,000,000 shares and the authorized common stock decreased to 4,000,000 shares. Both the preferred stock and common stock par value remained at $0.0001 per share. The number of authorized shares subsequently increased to 200,000,000 authorized shares of common stock and 50,000,000 authorized shares of preferred stock on September 3, 2015 with the Company’s reincorporation in Delaware, as described above. On the Effective Date, the total number of shares of common stock held by each stockholder of the Company were converted automatically into the number of shares of common stock equal to: (i) the number of issued and outstanding shares of common stock held by each such stockholder immediately prior to the Reverse Stock Split divided by (ii) 50. The Company issued one whole share of the post-Reverse Stock Split common stock to any stockholder who otherwise would have received a fractional share as a result of the Reverse Stock Split, determined at the beneficial owner level by share certificate. As a result, no fractional shares were issued in connection with the Reverse Stock Split and no cash or other consideration will be paid in connection with any fractional shares that would otherwise have resulted from the Reverse Stock Split. The Reverse Stock Split also affected all outstanding options and warrants by dividing each option or warrant outstanding by 50, rounded up to the nearest option or warrant, and multiplying the exercise price by 50 for each option or warrant outstanding. Description of the Business We design, develop, and manufacture products based on proprietary technologies that aim to expand the operating range of gaseous fuel while improving emissions, which technologies we refer to collectively as “Power Oxidation” or “Power Oxidizer” (previously called “Gradual Oxidation” and “Gradual Oxidizer,” respectively, in our prior public disclosures). Our products aim to expand power generation into previously uneconomical markets while, at the same time, reduce gaseous emissions from industrial processes that contribute to air pollution and climate change. The Power Oxidizer integrates with a gas turbine and generator to create a Powerstation. Our product, the EC250, is a complete system consisting of our designed and patented Power Oxidizer, integrated with a gas turbine and generator. The EC250 has been designed to operate on fuels from 100% combustible gas down to concentrations of 5% or less combustible gas content. The EC250 has applications in landfill, oil production, coal mining, and other operations, and offers our customers two distinct value propositions: the destruction of low quality waste gases with no harmful emissions and the generation of energy from a renewable fuel source. We are currently developing our second commercial product, the Ener-Core Powerstation KG2-3G/GO (“KG2”), which will combine our Power Oxidizer with a two megawatt gas turbine developed by Dresser-Rand a.s., a subsidiary of Dresser-Rand Group Inc. (“Dresser-Rand”). We have completed system layout and analytic models integrating our Power Oxidizer with the turbine and are constructing a full prototype KG2 unit. We expect to field test units in 2016, with initial commercial shipments shortly thereafter. We sell our products directly and through distributors in two countries, the United States and Netherlands. Going Concern Our consolidated financial statements are prepared using the accrual method of accounting in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and have been prepared on a going concern basis, which contemplates the realization of assets and settlement of liabilities in the normal course of business. Since our inception, we have made a substantial investment in research and development to develop the Power Oxidizer, have successfully deployed an EC250 field test unit at the U.S. Army base at Fort Benning, Georgia, and installed and commissioned our first commercial unit in the Netherlands in the second quarter of 2014. In November 2014, we signed a Commercial License Agreement with Dresser-Rand (as amended, the “CLA”) to incorporate our Power Oxidizer into Dresser-Rand’s 1.75MW turbine. In August 2015, the CLA became a mutually binding agreement due to the satisfaction of certain binding conditions contained in the CLA. We have sustained recurring net losses and negative cash flows since inception and have not yet established an ongoing source of revenues sufficient to cover our operating costs and allow us to continue as a going concern. Despite a capital raise of approximately $4.0 million in September 2014 and further capital raises of $5.8 million in April and May 2015, and $2.5 million in December 2015, we expect to require additional sources of capital to support the Company’s growth initiatives. We must secure additional funding to continue as a going concern and execute our business plan. Management’s plan is to obtain capital sufficient to meet our operating expenses by seeking additional equity and/or debt financing. The cash and cash equivalents balance (excluding restricted cash) on December 31, 2014 and December 31, 2015, was approximately $2.2 million and $2.8 million, respectively. We raised a total of $5.8 million of debt and equity capital in April and May 2015, as described in Notes 9 and 12 below, and $2.5 million of equity capital in December 2015 and we expect that the $2.8 million of cash as of December 31, 2015, receipts on customer billings, and the anticipated net proceeds from the proposed registered offering will continue to fund our working capital needs, general corporate purposes, and related obligations into 2016 at our current spending levels. However, we expect to require significantly more cash for working capital and as financial security to support our growth initiatives. We will pursue raising additional equity and/or debt financing to fund our operations and product development. If future funds are raised through issuance of stock or debt, these securities could have rights, privileges, or preferences senior to those of our common stock and debt covenants that could impose restrictions on our operations. Any equity or convertible debt financing will likely result in additional dilution to our current stockholders. We cannot make any assurances that any additional financing, including the proposed registered offering, will be completed on a timely basis, on acceptable terms or at all. Our inability to successfully raise capital in a timely manner will adversely impact our ability to continue as a going concern. If our business fails or we are unable to raise capital on a timely basis, our investors may face a complete loss of their investment. The accompanying consolidated financial statements do not give effect to any adjustments that might be necessary if we were unable to meet our obligations or continue operations as a going concern.

Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2—Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements include our accounts and our wholly-owned subsidiary, Ener-Core Power, Inc. All significant intercompany transactions and accounts have been eliminated in consolidation. All monetary amounts are rounded to the nearest $000, except certain per share amounts. The accompanying financial statements have been prepared in accordance with GAAP. Reclassifications Certain amounts in the 2015 consolidated condensed financial statements have been reclassified to conform to the current year presentation. These reclassifications have no effect on previously reported net loss. Segments We operate in one segment. All of our operations are located domestically. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Significant items subject to such estimates and assumptions include but are not limited to: collectability of receivables; the valuation of certain assets, useful lives, and carrying amounts of property and equipment, equity instruments and share-based compensation; provision for contract losses; valuation allowances for deferred income tax assets; valuation of derivative liabilities; and exposure to warranty and other contingent liabilities. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates. Foreign Currency Adjustments Our functional currency for all operations worldwide is the U.S. dollar. Nonmonetary assets and liabilities are translated at historical rates and monetary assets and liabilities are translated at exchange rates in effect at the end of the year. Income statement accounts are translated at average rates for the year. At September 30, 2016 and December 31, 2015, we did not hold any foreign currency asset or liability amounts. Gains and losses resulting from foreign currency transactions are reported as other income in the period they occurred. Concentrations of Credit Risk Cash and Cash Equivalents We maintain our non-interest bearing transactional cash accounts at financial institutions for which the Federal Deposit Insurance Corporation (“FDIC”) provides insurance coverage of up to $250,000. For interest bearing cash accounts, from time to time, balances exceed the amount insured by the FDIC. We have not experienced any losses in such accounts and believe we are not exposed to any significant credit risk related to these deposits. At September 30, 2016, we had $200,000 in deficit of the FDIC limit. We consider all highly liquid investments available for current use with an initial maturity of three months or less and are not restricted to be cash equivalents. We invest our cash in short-term money market accounts. Restricted Cash Collateral Account Under a credit card processing agreement with a financial institution that was entered in 2013, we are required to maintain funds on deposit with the financial institution as collateral. The amount of the deposit, which is at the discretion of the financial institution, was $50,000 on September 30, 2016 and December 31, 2015. Dresser-Rand Escrow Account Under the CLA, prepaid license fee payments of $400,000 per quarter were paid by Dresser-Rand into an escrow account with a financial institution beginning in August 2015. Dresser-Rand withdrew up to $125,000 per quarter from this escrow account for qualified engineering expenses incurred by Dresser-Rand under the terms and conditions of the CLA. Through September 26, 2016, Dresser-Rand funded $1,600,000 and withdrew $500,000. On September 26, 2016 substantially all of the remaining $1,100,000 was released to the Company from the escrow account and, in October 2016, the escrow account was closed. The balance in the escrow account was $5,000 and $150,000 on September 30, 2016 and December 31, 2015, respectively. See also Note 7—Deferred Revenues and Customer Advances. Accounts Receivable Our accounts receivable are typically from credit worthy customers or, for international customers are supported by guarantees or letters of credit. For those customers to whom we extend credit, we perform periodic evaluations of them and maintain allowances for potential credit losses as deemed necessary. We generally do not require collateral to secure accounts receivable. We have a policy of reserving for uncollectible accounts based on our best estimate of the amount of probable credit losses in existing accounts receivable. We periodically review our accounts receivable to determine whether an allowance is necessary based on an analysis of past due accounts and other factors that may indicate that the realization of an account may be in doubt. Account balances deemed to be uncollectible are charged to the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. As of September 30, 2016, one customer accounted for all of our accounts receivable. Accounts Payable As of September 30, 2016 and December 31, 2015, three and five vendors, respectively, collectively accounted for approximately 45% and 50% of our total accounts payable. Inventory Inventory, which consists of raw materials inventory consisting of Power Oxidizer parts and sub-assemblies of parts recorded as work-in-progress inventory, is stated at the lower of cost or net realizable value, with cost being determined by the average-cost method, which approximates the first-in, first-out method. At each balance sheet date, we evaluate our ending inventory for excess quantities and obsolescence. This evaluation primarily includes an analysis of forecasted demand in relation to the inventory on hand, among consideration of other factors. Based upon the evaluation, provisions are made to reduce excess or obsolete inventories to their estimated net realizable values. Once established, write-downs are considered permanent adjustments to the cost basis of the respective inventories. At September 30, 2016 and December 31, 2015, we did not have a reserve for slow-moving or obsolete inventory. Property and Equipment Property and equipment are stated at cost, and are being depreciated using the straight-line method over the estimated useful lives of the related assets, ranging from three to ten years. Maintenance and repairs that do not improve or extend the lives of the respective assets are expensed. At the time property and equipment are retired or otherwise disposed of, the cost and related accumulated depreciation accounts are relieved of the applicable amounts. Gains or losses from retirements or sales are reflected in the consolidated statements of operations. Deposits Deposits primarily consist of amounts incurred or paid in advance of the receipt of fixed assets or are deposits for rent and insurance. Accrued Warranties Accrued warranties represent the estimated costs that will be incurred during the warranty period of our products. We make an estimate of expected costs that will be incurred by us during the warranty period and charge that expense to the consolidated statement of operations at the date of sale. We also reevaluate the estimate at each balance sheet date and if the estimate is changed, the effect is reflected in the consolidated statement of operations. We had no warranty accrual at December 31, 2015 or September 30, 2016. We expect that most terms for future warranties of our Powerstations and Oxidizers will be one to two years depending on the warranties provided and the products sold. Accrued warranties for expected expenditures within one year are classified as current liabilities and as non-current liabilities for expected expenditures for time periods beyond one year. Deferred Rent We record deferred rent expense, included in accrued expenses, which represents the temporary differences between the reporting of rental expense on the financial statements and the actual amounts remitted to the landlord. The deferred rent portion of lease agreements are leasing inducements provided by the landlord. Also, tenant improvement allowances provided are recorded as a deferred rent liability and recognized ratably as a reduction to rent expense over the lease term. As of September 30, 2016 we had $4,000 of deferred rent, recorded in accrued expenses. Intangible Assets Our intangible assets represent intellectual property acquired during the reverse merger. We amortize our intangible assets with finite lives over their estimated useful lives. Impairment of Long-Lived Assets We account for our long-lived assets in accordance with the accounting standards which require that long-lived assets be reviewed for impairment whenever events or changes in circumstances indicate that the historical carrying value of an asset may no longer be appropriate. We consider the carrying value of assets may not be recoverable based upon its review of the following events or changes in circumstances: the asset’s ability to continue to generate income from operations and positive cash flow in future periods; loss of legal ownership or title to the assets; significant changes in our strategic business objectives and utilization of the asset; or significant negative industry or economic trends. An impairment loss would be recognized when estimated future cash flows expected to result from the use of the asset are less than its carrying amount. As of September 30, 2016 and December 31, 2015, we do not believe there have been any impairments of our long-lived assets. There can be no assurance, however, that market conditions will not change or demand for our products will continue, which could result in impairment of long-lived assets in the future. Fair Value of Financial Instruments Our financial instruments consist primarily of cash and cash equivalents, restricted cash, accounts receivable, accounts payable, convertible notes, derivative liabilities, and capital lease liabilities. Fair value estimates discussed herein are based upon certain market assumptions and pertinent information available to management as of September 30, 2016 and December 31, 2015. The carrying amounts of short-term financial instruments are reasonable estimates of their fair values due to their short-term nature or proximity to market rates for similar items. We determine the fair value of our financial instruments based on a three-level hierarchy established for fair value measurements under which these assets and liabilities must be grouped, based on significant levels of observable or unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect management’s market assumptions. This hierarchy requires the use of observable market data when available. These two types of inputs have created the following fair-value hierarchy: ● Level 1: Valuations based on unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Currently, we classify our cash and cash equivalents as Level 1 financial instruments. ● Level 2: Valuations based on observable inputs (other than Level 1 prices), such as quoted prices for similar assets at the measurement date quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability. We do not currently have any accounts under Level 2. ● Level 3: Valuations based on inputs that require inputs that are both significant to the fair value measurement and unobservable and involve management judgment (i.e., supported by little or no market activity). Currently, we classify our warrants and conversion options accounted for as derivative liabilities as Level 3 financial instruments. If the inputs used to measure fair value fall in different levels of the fair value hierarchy, a financial security’s hierarchy level is based upon the lowest level of input that is significant to the fair value measurement. Derivative Financial Instruments We issue derivative financial instruments in conjunction with its debt and equity offerings and to provide additional incentive to investors and placement agents. The Company uses derivative financial instruments in order to obtain the lowest cash cost-source of funds. Derivative liabilities are recognized in the consolidated balance sheets at fair value based on the criteria specified in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) topic 815-40 “ Derivatives and Hedging—Contracts in Entity’s own Equity The Company issued detachable common stock warrants and secured debt with a conversion feature in April and May 2015 and again in September 2016. We amended our existing debt to add a conversion feature in December 2015. The Company issued additional common stock warrants with price reset provisions in December 2015, February 2016, and March 2016. These embedded derivatives and detachable warrants were evaluated under ASC topic 815-40. We determined that the warrants and embedded conversion feature for the April 2014 issuance, the conversion feature for the 2015 issuances, the conversion feature for the 2016 issuance, and the warrants issued with price reset provisions should be accounted for as derivative liabilities. In August, 2016 all warrants issued that were previously determined to be accounted for as derivative liabilities were amended and we determined that after giving rise to the amendments, that the warrants were no longer required to be accounted for as derivative liabilities. We determined that the detachable warrants associated with the 2015 issuance on the issuance date and the detachable warrants associated with the 2016 issuance on the issuance date should not be accounted for as derivative liabilities. Warrants and the debt conversion features determined to be derivative liabilities were bifurcated from the debt host and are classified as liabilities on the consolidated balance sheet. Warrants not determined to be derivative liabilities were recorded to debt discount and paid-in capital. The Company records the warrants and embedded derivative liabilities at fair value and adjusts the carrying value of the common stock warrants and embedded derivatives to their estimated fair value at each reporting date with the increases or decreases in the fair value of such warrants and derivatives at each reporting date, recorded as a gain or (loss) in the consolidated statements of operations. The 2015 detachable warrants determined not to be derivative liabilities were recorded to debt discount with a corresponding entry to paid-in capital. The warrants amended in 2016 where the accounting was changed to eliminate derivative liability treatment were marked to market immediately prior to the amendment and the fair value was reclassified on the amendment date from derivative liabilities to paid in capital. Revenue Recognition We generate revenue from the sale of our clean power energy systems and from consulting services. Revenue is recognized when there is persuasive evidence of an arrangement, product delivery and acceptance have occurred, the sales price is fixed or determinable and collectability of the resulting receivable is reasonable assured. Amounts billed to clients for shipping and handling are classified as sales of product with related costs incurred included in cost of sales. Provisions for discounts and rebates to customers, estimated returns and allowances, and other adjustments are provided for in the same period the related revenue is recorded. We defer any revenue for which the services have not been performed or are subject to refund until such time that we and our customer jointly determine that the services have been performed or no refund will be required. Revenues under long-term construction contracts are generally recognized using the completed-contract method of accounting. Long-term construction-type contracts for which reasonably dependable estimates cannot be made or for which inherent hazards make estimates difficult are accounted for under the completed-contract method. Revenues under the completed-contract method are recognized upon substantial completion—that is acceptance by the customer, compliance with performance specifications demonstrated in a factory acceptance test or similar event. Accordingly, during the period of contract performance, billings and costs are accumulated on the balance sheet, but no profit or income is recorded before completion or substantial completion of the work. Anticipated losses on contracts are recognized in full in the period in which losses become probable and estimable. Changes in estimate of profit or loss on contracts are included in earnings on a cumulative basis in the period the estimate is changed. As of September 30, 2016 and December 31, 2015, we had a $600,000 provision for contract losses for both periods presented. Research and Development Costs Research and development costs are expensed as incurred. Research and development costs were $1,170,000 and $928,000 for the three months ended September 30, 2016 and 2015, respectively, and were $2,871,000 and $2,636,000 for the nine months ended September 30, 2016 and 2015, respectively. Share-Based Compensation We maintain an equity incentive plan and record expenses attributable to the awards granted under the equity incentive plan. We amortize share-based compensation from the date of grant on a weighted average basis over the requisite service (vesting) period for the entire award. We account for equity instruments issued to consultants and vendors in exchange for goods and services at fair value. The measurement date for the fair value of the equity instruments issued is determined at the earlier of (i) the date at which a commitment for performance by the consultant or vendor is reached or (ii) the date at which the consultant’s or vendor’s performance is complete. In the case of equity instruments issued to consultants, the fair value of the equity instrument is recognized over the term of the consulting agreement. In accordance with the accounting standards, an asset acquired in exchange for the issuance of fully vested, non-forfeitable equity instruments should not be presented or classified as an offset to equity on the grantor’s balance sheet once the equity instrument is granted for accounting purposes. Accordingly, we record the fair value of the fully vested, non-forfeitable common stock issued for future consulting services as prepaid expense in our consolidated balance sheets. Income Taxes We account for income taxes under FASB ASC 740 “Income Taxes.” Under the asset and liability method of FASB ASC 740, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Under FASB ASC 740, the effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period the enactment occurs. A valuation allowance is provided for certain deferred tax assets if it is more likely than not that we will not realize tax assets through future operations. Earnings (Loss) per Share Basic loss per share is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares assumed to be outstanding during the period of computation. Diluted loss per share is computed similar to basic loss per share except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potential shares had been issued and if the additional common shares were dilutive. The following approximate share amounts were excluded from the computation of diluted loss per share due to the anti-dilutive effect on net loss per share: September 30, September 30, Shares issuable for exercise of options and warrants 1,600,000 500,000 Full conversion of convertible senior secured and unsecured notes 1,500,000 — Total 3,100,000 500,000 All share and per share amounts in the table below have been adjusted to reflect the 1-for-50 reverse split of our issued and outstanding common stock on July 8, 2015, retroactively. Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 2016 2015 Net loss $ (1,596,000 ) $ (3,310,000 ) $ (7,628,000 ) $ (8,601,000 ) Weighted average number of common shares outstanding: Basic and diluted 3,785,216 2,464,100 3,591,233 2,385,500 Net loss attributable to common stockholders per share: Basic and diluted $ (0.42 ) $ (1.34 ) $ (2.12 ) $ (3.61 ) Comprehensive Income (Loss) We have no items of other comprehensive income (loss) in any period presented. Therefore, net loss as presented in our Consolidated Statements of Operations equals comprehensive loss. Recently Issued Accounting Pronouncements In May 2014, the FASB issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”).

Note 2—Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements include our accounts and our wholly-owned subsidiary, Ener-Core Power, Inc. All significant intercompany transactions and accounts have been eliminated in consolidation. All monetary amounts are rounded to the nearest $000, except certain per share amounts. The accompanying financial statements have been prepared in accordance with GAAP. Reclassifications Certain amounts in the 2014 consolidated financial statements have been reclassified to conform to the current year presentation. These reclassifications have no effect on previously reported net loss. Segments We operate in one segment. Except for one consultant operating in Europe, all of our operations are located domestically. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Significant items subject to such estimates and assumptions include but are not limited to: collectability of receivables; the valuation of certain assets, useful lives, and carrying amounts of property and equipment, equity instruments and share-based compensation; provision for contract losses; valuation allowances for deferred income tax assets; valuation of derivative liabilities; and exposure to warranty and other contingent liabilities. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates. Foreign Currency Adjustments Our functional currency for all operations worldwide is the U.S. dollar. Nonmonetary assets and liabilities are translated at historical rates and monetary assets and liabilities are translated at exchange rates in effect at the end of the year. Income statement accounts are translated at average rates for the year. At December 31, 2015 and 2014, we did not hold any foreign currency asset or liability amounts. Gains and losses resulting from foreign currency transactions are reported as other income in the period they occurred. Concentrations of Credit Risk Cash and Cash Equivalents We maintain our non-interest bearing transactional cash accounts at financial institutions for which the Federal Deposit Insurance Corporation (“FDIC”) provides insurance coverage of up to $250,000. For interest bearing cash accounts, from time to time, balances exceed the amount insured by the FDIC. We have not experienced any losses in such accounts and believe we are not exposed to any significant credit risk related to these deposits. At December 31, 2015, we had $2.5 million cash in excess of the FDIC limit. We consider all highly liquid investments available for current use with an initial maturity of three months or less and are not restricted to be cash equivalents. We invest our cash in short-term money market accounts. Restricted Cash Collateral Account Under a credit card processing agreement with a financial institution that was entered in 2013, we are required to maintain funds on deposit with the financial institution as collateral. The amount of the deposit, which is at the discretion of the financial institution, was $50,000 on December 31, 2015 and 2014. Dresser-Rand Escrow Account Under the CLA, prepaid license fee payments of $400,000 per quarter are to be paid by Dresser-Rand into an escrow account with a financial institution beginning August, 2015. Dresser-Rand is allowed to withdraw up to $125,000 per quarter from this escrow account for qualified engineering expenses incurred by Dresser-Rand under the terms and conditions of the CLA. Dresser-Rand funded $400,000 in August 2015 and withdrew $125,000 in August 2015. The balance in the escrow account was $150,000 and $0 on and December 31, 2015 and 2014 respectively. The Company is allowed to withdraw funds from the escrow account after completion of additional technical milestones, expected to be completed in the first half of 2016. See also Note 8—Deferred Revenues and Customer Advances. Accounts Receivable Our accounts receivable are typically from credit worthy customers or, for international customers are supported by guarantees or letters of credit. For those customers to whom we extend credit, we perform periodic evaluations of them and maintain allowances for potential credit losses as deemed necessary. We generally do not require collateral to secure accounts receivable. We have a policy of reserving for uncollectible accounts based on our best estimate of the amount of probable credit losses in existing accounts receivable. We periodically review our accounts receivable to determine whether an allowance is necessary based on an analysis of past due accounts and other factors that may indicate that the realization of an account may be in doubt. Account balances deemed to be uncollectible are charged to the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. As of December 31, 2015 and December 31, 2014, two customers and one customer, respectively, accounted for 100% of net accounts receivable. Accounts Payable As of December 31, 2015 and December 31, 2014, five and six vendors, respectively, collectively accounted for approximately 50% and 54% of our total accounts payable. Inventory Inventory, which consists of raw materials, is stated at the lower of cost or net realizable value, with cost being determined by the average-cost method, which approximates the first-in, first-out method. At each balance sheet date, we evaluate our ending inventory for excess quantities and obsolescence. This evaluation primarily includes an analysis of forecasted demand in relation to the inventory on hand, among consideration of other factors. Based upon the evaluation, provisions are made to reduce excess or obsolete inventories to their estimated net realizable values. Once established, write-downs are considered permanent adjustments to the cost basis of the respective inventories. At December 31, 2015 and 2014, we did not have a reserve for slow-moving or obsolete inventory. Property and Equipment Property and equipment are stated at cost, and are being depreciated using the straight-line method over the estimated useful lives of the related assets, ranging from three to ten years. Maintenance and repairs that do not improve or extend the lives of the respective assets are expensed. At the time property and equipment are retired or otherwise disposed of, the cost and related accumulated depreciation accounts are relieved of the applicable amounts. Gains or losses from retirements or sales are reflected in the consolidated statements of operations. Deposits Deposits primarily consist of amounts incurred or paid in advance of the receipt of fixed assets or are deposits for rent and insurance. Accrued Warranties Accrued warranties represent the estimated costs that will be incurred during the warranty period of our products. We make an estimate of expected costs that will be incurred by us during the warranty period and charge that expense to the consolidated statement of operations at the date of sale. We also reevaluate the estimate at each balance sheet date and if the estimate is changed, the effect is reflected in the consolidated statement of operations. We made our initial commercial sale to Efficient Energy Conversion TurboMachinery, B.V. (“EECT”) in the second quarter of 2014 with a six month warranty and later extended that warranty at our discretion. There was no warranty for the unit shipped to the Fort Benning site. We expect that most terms our future warranty period to be one to two years depending on the warranties provided and the products sold. Accrued warranties for expected expenditures within the next year are classified as current liabilities and as non-current liabilities for expected expenditures for time periods beyond one year. Deferred Rent We record deferred rent expense, which represents the temporary differences between the reporting of rental expense on the financial statements and the actual amounts remitted to the landlord. The deferred rent portion of lease agreements are leasing inducements provided by the landlord. Also, tenant improvement allowances provided are recorded as a deferred rent liability and recognized ratably as a reduction to rent expense over the lease term. Intangible Assets Our intangible assets represent intellectual property acquired during the reverse merger. We amortize our intangible assets with finite lives over their estimated useful lives. Impairment of Long-Lived Assets We account for our long-lived assets in accordance with the accounting standards which require that long-lived assets be reviewed for impairment whenever events or changes in circumstances indicate that the historical carrying value of an asset may no longer be appropriate. We consider the carrying value of assets may not be recoverable based upon our review of the following events or changes in circumstances: the asset’s ability to continue to generate income from operations and positive cash flow in future periods; loss of legal ownership or title to the assets; significant changes in our strategic business objectives and utilization of the asset; or significant negative industry or economic trends. An impairment loss would be recognized when estimated future cash flows expected to result from the use of the asset are less than its carrying amount. As of December 31, 2015 and 2014, we do not believe there have been any impairments of our long-lived assets. There can be no assurance, however, that market conditions will not change or demand for our products will continue, which could result in impairment of long-lived assets in the future. Fair Value of Financial Instruments Our financial instruments consist primarily of cash and cash equivalents, restricted cash, accounts receivable, accounts payable, derivative liabilities, secured notes payable and related debt discounts and capital lease liabilities. Fair value estimates discussed herein are based upon certain market assumptions and pertinent information available to management as of December 31, 2015 and 2014. The carrying amounts of short-term financial instruments are reasonable estimates of their fair values due to their short-term nature or proximity to market rates for similar items. We determine the fair value of our financial instruments based on a three-level hierarchy established for fair value measurements under which these assets and liabilities must be grouped, based on significant levels of observable or unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect management’s market assumptions. This hierarchy requires the use of observable market data when available. These two types of inputs have created the following fair-value hierarchy: ● Level 1: Valuations based on unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Currently, we classify our cash and cash equivalents as Level 1 financial instruments. ● Level 2: Valuations based on observable inputs (other than Level 1 prices), such as quoted prices for similar assets at the measurement date quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability. We do not currently have any accounts under Level 2. ● Level 3: Valuations based on inputs that require inputs that are both significant to the fair value measurement and unobservable and involve management judgment (i.e., supported by little or no market activity). Currently, we classify our warrants and conversion options accounted for as derivative liabilities as Level 3 financial instruments. If the inputs used to measure fair value fall in different levels of the fair value hierarchy, a financial security’s hierarchy level is based upon the lowest level of input that is significant to the fair value measurement. Derivative Financial Instruments The Company issues derivative financial instruments in conjunction with its debt and equity offerings and to provide additional incentive to investors and placement agents. The Company uses derivative financial instruments in order to obtain the lowest cash cost-source of funds. Derivative liabilities are recognized in the consolidated balance sheets at fair value based on the criteria specified in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) topic 815-40 “ Derivatives and Hedging—Contracts in Entity’s own Equity The Company issued detachable common stock warrants and convertible secured notes payable with conversion features in April 2014 and issued detachable common stock warrants and secured debt with a partial conversion feature in April and May 2015 and amended existing debt to add a conversion feature in December 2015. These embedded derivatives and detachable warrants were evaluated under ASC topic 815-40. We determined that the warrants and embedded conversion feature for the April 2014 issuance and the conversion feature for the 2015 issuances should be accounted for as derivative liabilities. We determined that the detachable warrants associated with the 2015 issuance should not be accounted for as derivative liabilities. Warrants and the debt conversion features determined to be derivative liabilities were bifurcated from the debt host and are classified as liabilities on the consolidated balance sheet. Warrants not determined to be derivative liabilities were recorded to debt discount and paid in capital. The Company records the warrants and embedded derivative liabilities at fair value and adjusts the carrying value of the common stock warrants and embedded derivatives to their estimated fair value at each reporting date with the increases or decreases in the fair value of such warrants and derivatives at each reporting date, recorded as a gain or (loss) in the consolidated statements of operations. The 2015 detachable warrants determined not to be derivative liabilities were recorded to debt discount with a corresponding entry to paid-in capital. Revenue Recognition Provisions for discounts and rebates to customers, estimated returns and allowances, and other adjustments are provided for in the same period the related revenue is recorded. We defer any revenue for which the services have not been performed or are subject to refund until such time that we and our customer jointly determine that the services have been performed or no refund will be required. Revenues under long-term construction contracts are generally recognized using the completed-contract method of accounting. Long-term construction-type contracts for which reasonably dependable estimates cannot be made or for which inherent hazards make estimates difficult are accounted for under the completed-contract method. Revenues under the completed-contract method are recognized upon substantial completion—that is acceptance by the customer, compliance with performance specifications demonstrated in a factory acceptance test or similar event. Accordingly, during the period of contract performance, billings and costs are accumulated on the balance sheet, but no profit or income is recorded before completion or substantial completion of the work. Anticipated losses on contracts are recognized in full in the period in which losses become probable and estimable. Changes in estimate of profit or loss on contracts are included in earnings on a cumulative basis in the period the estimate is changed. As of December 31, 2015 and December 31, 2014, we had $600,000 and no provision for contract losses respectively. Research and Development Costs Research and development costs are expensed as incurred. Research and development costs were $3,412,000 and $3,156,000 for the years ended December 31, 2015 and 2014, respectively. Share-Based Compensation We maintain an equity incentive plan and record expenses attributable to the awards granted under the equity incentive plan. We amortize share-based compensation from the date of grant on a weighted average basis over the requisite service (vesting) period for the entire award. We account for equity instruments issued to consultants and vendors in exchange for goods and services at fair value. The measurement date for the fair value of the equity instruments issued is determined at the earlier of (i) the date at which a commitment for performance by the consultant or vendor is reached or (ii) the date at which the consultant’s or vendor’s performance is complete. In the case of equity instruments issued to consultants, the fair value of the equity instrument is recognized over the term of the consulting agreement. In accordance with the accounting standards, an asset acquired in exchange for the issuance of fully vested, non-forfeitable equity instruments should not be presented or classified as an offset to equity on the grantor’s balance sheet once the equity instrument is granted for accounting purposes. Accordingly, we record the fair value of the fully vested, non-forfeitable common stock issued for future consulting services as prepaid expense in our consolidated balance sheets. Income Taxes We account for income taxes under the provisions of the accounting standards. Under the accounting standards, deferred tax assets and liabilities are recognized for the expected future tax benefits or consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. A valuation allowance is provided for significant deferred tax assets when it is more likely than not that such asset will not be realized through future operations. Our deferred tax assets and liabilities are primarily related to our Net Operating Losses and timing differences between book and tax accounting for depreciation and our net deferred tax assets were fully reserved as of December 31, 2015 and December 31, 2014. The accounting guidance for uncertainty in income taxes provides that a tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits. We recognize any uncertain income tax positions on income tax returns at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. As of December 31, 2015 and 2014 and there were no unrecognized tax benefits included in the consolidated balance sheets that would, if recognized, affect the effective tax rate. Our practice is to recognize interest and/or penalties related to income tax matters in income tax expense. We had no accrual for interest or penalties on our consolidated balance sheets at December 31, 2015 and 2014 and have not recognized interest and/or penalties in the consolidated statements of operations for the years ended December 31, 2015 or 2014. We are subject to taxation in the U.S. and various state and foreign jurisdictions. We do not foresee material changes to our gross uncertain income tax position liability within the next twelve months. Earnings (Loss) per Share Basic loss per share is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares assumed to be outstanding during the period of computation. Diluted loss per share is computed similar to basic loss per share except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potential shares had been issued and if the additional common shares were dilutive. Approximately 1,084,000 and 462,000 shares of common stock issuable upon full exercise of all options and warrants at December 31, 2015 and 2014, respectively and all shares potentially issuable in the future under the terms of the Secured Notes Payable were excluded from the computation of diluted loss per share due to the anti-dilutive effect on the net loss per share. All share and per share amounts in the table below have been adjusted to reflect the 1-for-50 reverse split of our issued and outstanding common stock on July 8, 2015, retroactively. Year ended Year ended December 31, Net loss $ (13,107,000 ) $ (10,534,000 ) Weighted average number of common shares outstanding: Basic and diluted 2,405,147 1,707,620 Net loss attributable to common stockholders per share: Basic and diluted $ (5.45 ) $ (6.17 ) Comprehensive Income (Loss) We have no items of other comprehensive income (loss) in any period presented. Therefore, net loss as presented in our Consolidated Statements of Operations equals comprehensive loss.

The two tranches of the 2015 Notes were identical, other than the issuance date and the term of the respective Note tranches and the term of the related detachable warrants, described in greater detail below. On April 23, 2015, the Company closed the first tranche representing $3.1 million in aggregate principal amount of 2015 Notes issued in a private placement to seven institutional investors and on May 7, 2015 the Company closed the second tranche, representing $1.9 million in aggregate principal amount of 2015 Notes to four institutional investors. The Company received total gross proceeds of $5.0 million, less transaction expenses of $0.3 million consisting of legal costs and placement agent fees. The 2015 Notes bear interest at a rate of 12% per year, payable monthly, and are set to mature on the two-year anniversary of the issuance dates of the 2015 Notes on April 23, 2017 and May 7, 2017 for the first and second tranches, respectively. Upon issuance of the 2015 Notes, each investor, at its discretion, was entitled to convert up to 50% of the balance outstanding under the 2015 Notes. Upon the execution of the December Amendments (as defined below), however, each investor became entitled to fully convert 100% of the balance outstanding under the 2015 Notes may be into shares of the Company’s common stock. The 2015 Notes may be repaid by the Company at any time unless the 2015 Notes are in default. The 2015 Notes are secured by substantially all assets of the Company and provide for specified events of default, including: (i) failure to pay principal and interest when due, and (ii) failure to effectuate a reverse stock split on or prior to the three-month anniversary of the first tranche of 2015 Notes, which the Company effectuated in July 2015. The 2015 Notes previously required the Company to consummate a Qualified Public Offering on or prior to the six-month anniversary of the first tranche of 2015 Notes. This default condition, however, was amended as described in greater detail below. Any event of default may be waived by the holders of at least a majority of the aggregate principal amount of 2015 Notes, which must include a specified holder under specified circumstances. Upon the occurrence of an event of default, the interest rate immediately increases to 18% per annum and the 2015 Notes become convertible at a price per share equal to 85% of the average of the five lowest volume weighted average prices of the Company’s common stock during a 15 consecutive trading day period immediately prior to the applicable conversion date. Each holder may require us to redeem the 2015 Notes at a price equal to 115% of the sum of portion of the principal to be redeemed plus accrued and unpaid interest thereon and any accrued and unpaid late charges, if any, with respect to such principal and interest (the “Conversion Amount”) being redeemed (a) upon our default under the Sen2015 ior Notes, or (b) if we enter into a merger or consolidation, or sell or assign all or substantially all of our assets. In addition, at any time from and after the date that is the eighteen-month anniversary of the original issuance date of the 2015 Notes, each holder has the right, in its sole and absolute discretion, at any time or times, to require that we redeem all or any portion of the Conversion Amount of its 2015 Note then outstanding at a price equal to 100% of the Conversion Amount of the portion of the 2015 Note being redeemed. At any time after the issuance of the 2015 Notes, other than (i) at any time during which an event of default has occurred and is continuing or (ii) from the time we publicly announce a Qualified Public Offering through and including the date that is thirty days immediately following the consummation of such Qualified Public Offering, we have the right to redeem all or any portion of the Conversion Amount then remaining under the 2015 Notes, (a “Company Optional Redemption”); provided, that the aggregate Conversion Amount under 2015 Notes being redeemed must be at least $500,000, or such lesser amount that is then outstanding under the 2015 Notes. The conversion price for such Company Optional Redemption would be a price equal to 100% of the Conversion Amount of the 2015 Notes being redeemed. The 2015 Notes were originally issued with detachable warrants to purchase 219,785 shares of the Company’s common stock, exercisable for five years with an exercise price of $12.50 per share (the “April and May Warrants”). In August 2016, the Company adjusted the exercise price of such April and May Warrants to $4.00 per share. The Company evaluated the accounting of the April and May Warrants and determined that such warrants should not be accounted for as derivative liabilities. Between May 2015 and September 2016, the Company and certain investors holding the requisite number of conversion shares and warrant shares underlying the 2015 Notes and April and May Warrants executed several amendments to the Securities Purchase Agreements dated April 22, 2015 and May 7, 2015, respectively, related to the extension or modification of the debt covenants. Effective as of December 30, 2015, the Company executed a Fourth Amendment to Securities Purchase Agreement dated April 22, 2015, and a Third Amendment to Securities Purchase Agreement dated May 7, 2015 (collectively, the “December Amendments”), each with certain investors holding the requisite number of conversion shares and warrant shares underlying the 2015 Notes and April and May Warrants pursuant to the referenced Securities Purchase Agreements. The December Amendments (i) extended the deadline to March 31, 2016 for the Company’s consummation of a firm commitment underwritten public offering registered under the Securities Act and related listing of its Common Stock on a national securities exchange, (ii) provided for the issuance of additional five-year warrants (the “Additional Warrants”), exercisable for ten shares of Common Stock per $1,000 of outstanding principal of the 2015 Notes held by each buyer pursuant to the April 2015 and May 2015 Securities Purchase Agreements, each with an exercise price of $12.50 per share, subject to adjustment as set forth within the Additional Warrants, issuable in tranches triggered by certain Company actions as set forth in the December Amendments and (iii) authorized the Company, prior to January 31, 2016, to issue to one or more investors up to an aggregate of $1,000,000 principal amount of senior secured notes, on the terms and subject to the restrictions set forth in the December Amendments. An initial tranche of Additional Warrants to purchase up to 50,000 shares of the Company’s common stock were issued in conjunction with the execution of the December Amendments (the “December Warrants”). The December Amendments also amended the terms of the 2015 Notes to allow for 100% of the balance outstanding under the 2015 Notes to be converted into shares of the Company’s common stock. The modification for the additional conversion feature was accounted for as a debt extinguishment. The Company accelerated the original debt discount to “other expense—debt extinguishment” and recorded additional debt discounts consisting of $609,000 for the fair value of the beneficial conversion feature and $182,000 for the fair value of the December Warrants issued. On February 2, 2016, due to the Company’s failure to conclude its public offering, the Company issued Additional Warrants to purchase an aggregate of up to 50,000 shares of the Company’s common stock on the same terms as the December Warrants (the “February Warrants”). On March 31, 2016, the Company executed amendments to the 2015 Notes and related Securities Purchase Agreements (collectively, the “March Amendments”), each with certain investors holding the requisite number of conversion shares and warrant shares underlying the 2015 Notes and April and May Warrants pursuant to the referenced Securities Purchase Agreements. The March Amendments (i) removed the requirement that the Company consummate a “Qualified Public Offering”; (ii) extended the deadline for the Company to commence trading on a Qualified Eligible Market (as defined in the March Amendments) to no later than April 14, 2016; provided that if the Company consummated a private offering of its securities resulting in gross proceeds to the Company of at least $3,000,000 after March 31, 2016 and prior to or on April 14, 2016 (a “Qualified Private Offering”), such deadline would be automatically extended to October 15, 2016; (iii) provided for the issuance of warrants to purchase up to 500,000 shares of the Company’s common stock, each with an exercise price of $5.00 per share, subject to adjustment as set forth within the warrants (the “March Warrants”); and (iv) added an additional covenant on behalf of the Company that, on or prior to April 14, 2016, it would cause its net monthly cash flow directly associated with the CLA, taken together with its monthly capital expenditure spending associated with the CLA, and excluding expenditures associated with the FSAT requirements defined in the CLA, to be neutral or positive, to be accomplished by re-negotiation or termination of such CLA. On April 11, 2016, we consummated a $3 million private offering and thereby satisfied condition (ii) above. On March 31, 2016 we issued the March Warrants, as described in Note 12, and we remained in compliance with the net monthly cash flow covenant listed in (iv) above during all relevant times. On June 29, 2016, we signed the CMLA, which will replace the CLA upon the successful completion of the technical tests associated with the KG2. Additionally, upon execution of the September Amendments (as defined below), the monthly cash flow covenant listed in (iv) above was removed. In connection with the issuance of the March Warrants, the exercise price of the December Warrants and February Warrants was reduced to $5.00 per share. The Company evaluated the February Warrants and the March Warrants and determined that both issuances should be accounted for as derivative liabilities on the date of issuance. The Company recorded an additional $148,000 of debt discount upon the issuance of the February Warrants and $1,497,000 of debt discount upon the issuance of the March Warrants. The December 31, 2015 debt discount and the additional discounts recorded in February 2016 and March 2016 are amortized over the expected remaining life of the debt. On August 24, 2016, the April and May Warrants, December Warrants, February Warrants, and March Warrants were all amended to (i) reduce the exercise price of such warrants to $4.00 per share and (ii) remove the net cash settlement option which had given rise to derivative accounting. The warrants accounted for as derivative liabilities were marked to market at the $5.00 exercise price immediately prior to the amendment with any change in value recorded to income. The warrants with price adjustment from $12.50 per share to $4.00 per share were not previously accounted for as derivative liabilities. The foregoing warrants were then revalued with an amended exercise price of $4.00 and the difference in fair value resulting from an exercise price reduction of $12.50 per share to $4.00 per share, in the case of the April and May Warrants, and from $5.00 per share to $4.00 per share, in the case of the December Warrants, February Warrants and March Warrants, was recorded as an additional debt discount of $206,000, which will be amortized over the expected remaining life of the 2015 Notes. Effective as of September 1, 2016, the Company executed amendments to the 2015 Notes and related Securities Purchase Agreements (collectively, the “September Amendments”), which are binding upon all of the 2015 Notes. The September Amendments (i) extend the deadline for the Company to commence trading on a Qualified Eligible Market (as defined in the September Amendments) to no later than December 31, 2016; (ii) provide that the Company may, on or prior to September 1, 2016, issue to one or more investors up to an aggregate of $1,500,000 principal amount of one-year term unsecured notes, as described in Note 9 below, and related warrants, and approve the forms of agreements to be executed in connection with the issuance of such unsecured notes and warrants; (iii) remove the covenant on behalf of the Company related to net monthly cash flow directly associated with the CLA, as described above; (iv) extend the earliest date on which the holders of the 2015 Notes may require the Company to redeem all or any portion of such 2015 Notes until December 31, 2016; and (v) extend the deadline for the Company to consummate a Further Private Offering (as defined in the 2015 Notes) to December 31, 2016. Effective as of October 21, 2016, the Company executed amendments to the 2015 Notes to clarify and conform the terms of such 2015 Notes to the terms of previous amendments to such 2015 Notes and the related Securities Purchase Agreements. Derivative Liabilities We evaluate any freestanding financial instruments or embedded features that have the characteristics of a derivative, and to any freestanding financial instruments that are potentially settled in an entity’s own common stock to determine if they are indexed to an entity’s own stock. During the fiscal year ended December 31, 2015, we determined that the issuance of the 2015 Notes contained an embedded note conversion feature that is required to be accounted for as a derivative. In December 2015, we modified the conversion feature which gave rise to additional derivative liabilities and issued to the debt holders the December Warrants that included a price reset provision and net cash settlement option. The inclusion of the price reset provision and contingent net cash settlement provision required us to treat the December Warrants as derivative liabilities and increase the debt discount for the initial value of the derivative liability. Also, in December 2015, we issued warrants to purchase an aggregate of up to 312,500 shares of the Company’s common stock to the investors in the December 2015 equity offering (the “December Offering Warrants”). The December Offering Warrants include limited price reset and net cash settlement provisions, until the earlier of June 30, 2016 or upon the registration of the December 2015 equity securities. This price protection clause expired on June 30, 2016. We recorded the fair value of the December Offering Warrants issued as a derivative liability with a corresponding decrease in additional paid-in capital. In the first quarter of 2016, we issued the February Warrants and March Warrants to the holders of the 2015 Notes in exchange for the waiver of certain debt covenants. The February Warrants and March Warrants were in substantially identical form to the December Offering Warrants and December Warrants. We recorded the fair value of the February Warrants and March Warrants issued as a derivative liability with a corresponding increase in debt discount. In September 2016 we issued convertible unsecured notes with an embedded conversion feature that is required to be accounted for as a derivative. In August 2016 we amended the terms of all warrants accounted for as derivatives to eliminate the potential net settlement and price adjustment provisions which gave rise to derivative accounting treatment. We marked the warrants to market immediately prior to the amendment and reclassified the remaining fair value to paid in capital. The embedded conversion features and common stock purchase warrants do not trade in an active securities market, and as such, we estimate the fair value of these warrants and embedded conversion features using the Black-Scholes pricing model using the following assumptions: 2016 Annual dividend yield — Expected life (years) 0.1–5 years Risk-free interest rate 0.5–0.9 % Expected volatility 98–107 % Expected volatility is based primarily on historical volatility of us and our peer group. Historical volatility was computed using weekly pricing observations for us and daily pricing observations for our peer group for recent periods that correspond to the expected term. We believe this method produces an estimate that is representative of our expectations of future volatility over the expected term of these warrants. We currently have no reason to believe future volatility over the expected remaining life of these warrants is likely to differ materially from historical volatility. The expected life is based on the remaining term of the warrants. The risk-free interest rate is based on one-year to five-year U.S. Treasury securities consistent with the remaining term of the warrants. Derivative liabilities consisted of the following (unaudited): Warrants Liability Embedded Note Conversion Feature Total Value as of December 31, 2015 $ 1,297,000 $ 1,213,000 $ 2,510,000 Adjustment to fair value (1,223,000 ) (1,901,000 ) (3,124,000 ) Additional Warrants issued for debt amendment 1,645,000 — 1,645,000 Modification of Conversion Feature—debt amendment — 1,429,000 1,429,000 Warrant amendment—August 24, 2016 (1,719,000 ) — (1,719,000 ) Issuance of Convertible Unsecured Notes—September 1, 2016 — 282,000 282,000 Ending balance—September 30, 2016 $ — $ 1,023,000 $ 1,023,000 On August 24, 2016, we amended the terms of all warrants that had been previously accounted for as derivative liabilities. The amendments reduced the exercise price of each warrant series to $4.00 per share and removed net cash settlement language, and any price reset provisions had since lapsed. After the execution of the amendments, we determined that the December Offering Warrants, December Warrants, February Warrants and March Warrants were no longer required to be accounted for as derivative liabilities. We marked each warrant to market immediately prior to the execution of the amendments and reduced the derivative liability associated with each warrant to zero with a corresponding increase to paid-in capital. On September 1, 2016 we issued $1,250,000 of convertible unsecured notes (the “Convertible Unsecured Notes”), as described in Note 9. The Convertible Unsecured Notes include an embedded conversion feature that is required to be accounted for as a derivative valued at $282,000 on the date of issuance. As of September 30, 2016, the embedded conversion feature attributable to the Convertible Unsecured Notes was valued at $266,000 and the embedded conversion feature attributable to the Convertible Unsecured was valued at $757,000.

Secured Notes Payable	12 Months Ended

Debt Disclosure [Abstract]
Secured Notes Payable	Note 9—Secured Notes Payable Secured Notes During the year ended December 31, 2015, the Company sold senior secured promissory notes with an aggregate principal amount of $5.0 million (the “Notes”) in two separate tranches. Other than the issuance date and the term of the respective notes and warrants issued, the notes and warrants were identical for both tranches. On April 23, 2015, the Company closed the first tranche representing $3.1 million in aggregate principal amount of Notes issued in a private placement to seven institutional investors and on May 7, 2015 the Company closed the second tranche, representing $1.9 million in aggregate principal amount of Notes to four institutional investors. The Company received total gross proceeds of $5.0 million, less transaction expenses of $0.3 million consisting of legal costs and placement agent fees. The Company agreed to pay the placement agent 5% of the aggregate principal amount of the Notes, which was paid at the closing date of the second tranche. The Company plans to continue to use the proceeds from the Notes offering for general corporate purposes. The Notes bear interest at a rate of 12% per year, payable monthly, and are set to mature on the two-year anniversary of the issuance dates of the Secured Notes on April 23, 2017 and May 7, 2017 for the first and second tranches, respectively. The Notes have a limited conversion feature. At the discretion of each investor, at issuance, 50% of the principal balance of the Notes, later amended to be 100% of the Notes may be exchanged for shares of the Company’s common stock if the Company consummates a registered underwritten public offering of equity securities with aggregate gross offering proceeds of at least $10 million (the “Qualified Public Offering”). The conversion period begins on the date of the consummation of the Qualified Public Offering and ends thirty days after the consummation of the Qualified Public Offering (the “Conversion Period”). The conversion price is the price per share of common stock sold in the Qualified Public Offering. The Notes may be repaid by the Company at any time except during a Conversion Period and unless the Notes are in default. The Notes are secured by substantially all assets of the Company and provides for specified events of default, including: i) failure to pay principal and interest when due, and ii) failure to effectuate a reverse stock split on or prior to the three-month anniversary of the first tranche of Notes. In addition, the Company must consummate a Qualified Public Offering on or prior to the six-month anniversary of the first tranche of Notes. Any event of default may be waived by the holders of at least a majority of the aggregate principal amount of Notes, which must include a specified holder under specified circumstances. Upon the occurrence of an event of default, the interest rate immediately increases to 18% per annum and the Notes become convertible at a price per share equal to 85% of the average of the five lowest volume weighted average prices of the Company’s common stock during a 15 consecutive trading day period immediately prior to the applicable conversion date. The Notes were issued with detachable warrants to purchase 219,785 shares of the Company’s common stock, exercisable for five years with an exercise price of $12.50 per share. The Company valued the warrants issued using the Black-Scholes option model at a combined $2,139,000 using an exercise price of $12.50 per share, a grant date fair value of $11.00–$11.25 per share, a risk free rate of 0.87%–1.02%, a five-year life, and a volatility of 78%–83% for the April 23, 2015 and May 7, 2015 warrant valuations. The Company evaluated the accounting of the detachable warrants and determined that the warrants should not be accounted for as derivative liabilities. The Company valued the initial 50% conversion embedded conversion feature using the Black Scholes option model at a combined $611,000 representing an option to convert $2,500,000 of debt at market prices until 30 days following the deadline of the Qualified Public Offering covenant using an exercise price and grant date fair value of $11.00–$11.25 per share, a risk free rate of 0.23%–0.25%, a seven-month life, and a volatility of 138%–148%. The Company evaluated the accounting of the embedded conversion feature and determined that they should be accounted for as derivative liabilities. On December 30, 2015 the Company and the note holders amended the terms of the Notes to allow for the remaining 50% to be converted. The Company valued the additional 50% conversion embedded conversion feature using the Black Scholes option model at a combined $609,000 representing an option to convert $2,500,000 of debt at market prices until 30 days following the deadline of the Qualified Public Offering covenant using an exercise price and grant date fair value of $4.45 per share, a risk free rate of 0.48%, a four-month life, and a volatility of 107%. The Company evaluated the accounting of the embedded conversion feature and determined that they should be accounted for as derivative liabilities. Each holder may require us to redeem the Notes at a price equal to 115% of the sum of portion of the principal to be redeemed plus accrued and unpaid interest thereon and any accrued and unpaid late charges, if any, with respect to such principal and interest (the “Conversion Amount”) being redeemed (a) upon our default under the Notes, or (b) if we enter into a merger or consolidation, or sell or assign all or substantially all of our assets. In addition, at any time from and after the date that is the eighteen-month anniversary of the original issuance date of the Notes, each holder shall have the right, in its sole and absolute discretion, at any time or times, to require that we redeem all or any portion of the Conversion Amount of its Note then outstanding at a price equal to 100% of the Conversion Amount of the portion of the Note being redeemed. At any time after the issuance of the Notes, other than (i) at any time during which an event of default has occurred and is continuing or (ii) from the time we publicly announce a Qualified Public Offering through and including the date that is thirty days immediately following the consummation of such Qualified Public Offering, we have the right to redeem all or any portion of the Conversion Amount then remaining under the Notes, or a Company Optional Redemption; provided, that the aggregate Conversion Amount under Notes being redeemed shall be at least $500,000, or such lesser amount that is then outstanding under the Notes. The conversion price for such Company Optional Redemption shall be a price equal to 100% of the Conversion Amount of the Notes being redeemed. The Notes were initially recorded net of a discount of $2,750,000, reflecting the fair value of the warrants and embedded conversion feature derivatives within the Notes on the issuance date and $303,000 of offering costs, representing cash placement fees and legal expenses. Both the $2,750,000 debt discount and the $303,000 of offering costs will be amortized through interest expense on the consolidated statements of operations, using the effective interest method, over the expected term of the Notes. Effective as of October 22, 2015, the Company executed a Second Amendment to Securities Purchase Agreement dated April 22, 2015, and a First Amendment to Securities Purchase Agreement dated May 7, 2015 (collectively, the “October Amendments”), each with certain investors holding the requisite number of conversion shares and warrant shares underlying the notes and warrants issued in April 2015 and May 2015 pursuant to the referenced purchase agreements. The October Amendments extend the deadline to November 30, 2015 for the Company’s consummation of a firm commitment underwritten public offering registered under the Securities Act of 1933, as amended (the “Securities Act”), with aggregate gross proceeds to the Company equal to or in excess of $10,000,000, and related listing of its common stock on a national securities exchange. Effective as of November 24, 2015, the Company executed a Third Amendment to the Securities Purchase Agreement dated April 22, 2015, and a Second Amendment to Securities Purchase Agreement dated May 7, 2015 (collectively, the “November Amendments”, each with certain investors holding the requisite number of conversion shares and warrant shares underlying the notes and warrants issued in April 2015 and May 2015 pursuant to the referenced purchase agreements. The November Amendments further extend the deadline to December 31, 2015 for the Company’s consummation of a firm commitment underwritten public offering registered under the Securities Act with aggregate gross proceeds to the Company equal to or in excess of $10,000,000, and related listing of its common stock on a national securities exchange. Effective as of December 30, 2015, the Company executed a Fourth Amendment to Securities Purchase Agreement dated April 22, 2015, and a Third Amendment to Securities Purchase Agreement dated May 7, 2015 (collectively, the “December Amendments”), each with certain investors holding the requisite number of conversion shares and warrant shares underlying the notes and warrants issued in April 2015 and May 2015 pursuant to the referenced purchase agreements. The December Amendments (i) extend the deadline to March 31, 2016 for the Company’s consummation of a firm commitment underwritten public offering registered under the Securities Act and related listing of its Common Stock on a national securities exchange, (ii) provide for the issuance of additional five-year warrants (the “Additional Warrants”), exercisable for ten shares of Common Stock per $1,000 of outstanding principal of the 2015 Notes (defined below) held by each buyer pursuant to the April 2015 and May 2015 purchase agreements, each with an exercise price of $12.50 per share, subject to adjustment as set forth within the warrants, issuable in tranches triggered by certain Company actions as set forth in the December Amendments and (iii) authorize the Company, prior to January 31, 2016, to issue to one or more investors up to an aggregate of $1,000,000 principal amount of senior secured notes, on the terms and subject to the restrictions set forth in the December Amendments. An initial tranche of 50,000 Additional Warrants became issuable and were issued in conjunction with the execution of the December Amendments. The December Amendments also amended the terms of the Notes to allow for the remaining 50% to be converted under the same terms as the original 50% as described above. The modification for the additional conversion feature was accounted for as a debt extinguishment. The Company accelerated the original debt discount to other expense – debt extinguishment and recorded additional debt discounts consisting of the $609,000 for the fair value of the beneficial conversion feature and $182,000 for the fair value of the Additional Warrants issued. On March 31, 2016, the Company executed amendments to the April 22, 2015, and May 7, 2015 Note Agreements and related Securities Purchase Agreements (collectively, the “March Amendments”), each with certain investors holding the requisite number of conversion shares and warrant shares underlying the notes and warrants issued in April 2015 and May 2015 pursuant to the referenced purchase agreements. The March Amendments (i) remove the requirement that the Company consummate a “Qualified Public Offering”; (ii) extend the deadline for the Company to commence trading on a Qualified Eligible Market (as defined in the March Amendments) to no later than April 14, 2016; provided that if the Company consummates a private offering of its securities resulting in gross proceeds to the Company of at least $3,000,000 after March 31, 2016 and prior to or on April 14, 2016 (a “Qualified Private Offering”), such deadline shall be automatically extended to October 15, 2016; (iii) provide for the issuance of the Additional Warrants, exercisable for ten shares of the Company’s common stock per $100 of outstanding principal of the 2015 Notes held by each buyer pursuant to the April 2015 and May 2015 Securities Purchase Agreements, each with an exercise price of $5.00 per share, subject to adjustment as set forth within the warrants; and (iv) add an additional covenant on behalf of the Company that, on or prior to April 14, 2016, it will cause its net monthly cash flow directly associated with the CLA, taken together with its monthly capital expenditure spending associated with the CLA, and excluding expenditures associated with the Full-Scale Acceptance Test (“FSAT”) requirements defined in the CLA, to be neutral or positive, which may be accomplished by re-negotiation or termination of such CLA. Notes payable consisted of the following as of December 31, 2015: Notes Debt Offering Costs Net Original Value $ 5,000,000 $ (2,750,000 ) (303,000 ) $ 1,947,000 Amortization of debt discount and deferred financing costs — 2,043,000 204,000 2,247,000 Acceleration of debt discount—extinguishment — 707,000 — 707,000 Additional debt discount—modification — (791,000 ) — (791,000 ) Ending balance—December 31, 2015 5,000,000 (791,000 ) (99,000 ) 4,110,000 Less: Current Portion (5,000,000 ) 791,000 99,000 (4,110,000 ) Long Term Portion $ — $ — — $ — Derivative Liabilities We evaluate any freestanding financial instruments or embedded features that have the characteristics of a derivative, and to any freestanding financial instruments that are potentially settled in an entity’s own common stock to determine if they are indexed to an entity’s own stock. During 2015, we determined that the issuance of the 2015 Notes in April and May 2015 contained an embedded note conversion feature that is required to be accounted for as a derivative. In December 2015, we modified the conversion feature which gave rise to additional derivative liabilities and issued warrants to the debt holders that allowed for price reset provisions. The inclusion of the price reset provisions required treatment of the warrants issued to the debt holders as derivative liabilities and an increase in debt discount for the initial value of the derivative liability. Also in December 2015, we issued 312,500 warrants to the investors in the December 2015 equity offering. The warrants carry limited price reset provisions, until the earlier of June 30, 2016 or upon the registration of the December 2015 equity securities. We recorded the fair value of the warrants issued as a derivative liability with a corresponding decrease in additional paid in capital. After the price reset provisions lapse, the fair value of the warrants, marked to market value on the date of the provision lapse, will be adjusted to additional paid in capital. Derivative liabilities consisted of the following: Warrants Liability Embedded Note Conversion Feature Total Value as of December 31, 2014 $ 402,000 $ — $ 402,000 Adjustment to fair value—warrants 205,000 — 205,000 Exchange of warrants for common stock—April 2, 2015 $ (607,000 ) $ — $ (607,000 ) Issuance of Notes in April/May 2015 — 611,000 611,000 Additional conversion feature added December 2015 — 609,000 609,000 Additional Warrants issued for debt amendment 182,000 — 182,000 Warrants issued pursuant to PIPE transaction 1,115,000 — 1,115,000 Adjustment to fair value—conversion features — (7,000 ) (7,000 ) Ending balance—December 31, 2015 $ 1,297,000 $ 1,213,000 $ 2,510,000 Warrant Liability: We issued warrants for the purchase of up to 81,942 shares of our common stock in conjunction with our April 2014 convertible notes offering. During 2014, the convertible notes were either redeemed or converted into common stock of the Company. The warrants that were issued with the April 2014 convertible notes were not issued with the intent of effectively hedging any future cash flow, fair value of any asset, liability or any net investment in a foreign operation. The warrants do not qualify for hedge accounting, and as such, all future changes in the fair value of these warrants will be recognized currently in earnings until such time as the warrants are exercised or expire. These warrants do not trade in an active securities market, and as such, we estimate the fair value of these warrants and embedded conversion features using the Binomial pricing model using the following assumptions: 2015 Annual dividend yield — Expected life (years) 4.04 Risk-free interest rate 0.99 % Expected volatility 134 % Expected volatility is based primarily on historical volatility of us and our peer group. Historical volatility was computed using weekly pricing observations for us and daily pricing observations for our peer group for recent periods that correspond to the expected term. We believe this method produces an estimate that is representative of our expectations of future volatility over the expected term of these warrants. We currently have no reason to believe future volatility over the expected remaining life of these warrants is likely to differ materially from historical volatility. The expected life is based on the remaining term of the warrants. The risk-free interest rate is based on one-year to five-year U.S. Treasury securities consistent with the remaining term of the warrants. On April 2, 2015, we entered into a warrant exchange agreement with five institutional investors as describe in Notes 11 and 12 below. As a result of this exchange, we marked the warrants to market on April 2, 2015 and exchanged 81,942 warrants for 73,747 shares of common stock. The shares of common stock were issued to the investors on April 17, 2015. We incurred a loss of $279,000 as a result of the exchange, recorded in other expense in the consolidated statement of operations. Embedded conversion feature liability: The Notes were issued with a feature that allows for up to 50% of the principal to be converted into our common stock. On December 30, 2015, the terms of the Notes were amended to allow the remaining 50% of the principal to be convertible into our common stock. We determined that these embedded conversion features should be accounted for as derivatives. The grant date fair value of the embedded derivatives, which requires bifurcation from the Notes described above, were recorded within short-term liabilities on the consolidated balance sheet. The embedded derivatives relate to the conversion option, redemption in the case of an event of default and redemption in the case of a change in control features of the convertible secured note. The embedded derivatives will be marked to market quarterly, with any change recorded as an adjustment to the carrying value of these liabilities and the gain or (loss) on warrants and derivatives liabilities recorded in the consolidated statements of operations. The fair value of embedded derivatives from the issuance date to December 31, 2015 declined by $7,000. Accordingly, this amount was recorded as a gain on derivative liabilities in the consolidated statements of operations. The embedded derivatives were valued using Black-Scholes option pricing model where the exercise price was equal to the market price on the valuation date and the following assumptions: 2015 Annual dividend yield — Expected life (years) 0.1-0.6 years Risk-free interest rate 0.22-0.48 % Expected volatility 107–148 % Expected volatility is based primarily on historical volatility of us and our peer group. Historical volatility was computed using weekly pricing observations for us and daily pricing observations for our peer group for recent periods that correspond to the expected term. We believe this method produces an estimate that is representative of our expectations of future volatility over the expected term of these warrants. We currently have no reason to believe future volatility over the expected remaining life of these embedded derivatives is likely to differ materially from historical volatility. The expected life is based on the remaining term of the conversion option. The risk-free interest rate is based on the U.S. Treasury securities consistent with the remaining term of the embedded derivatives.

Convertible Unsecured Notes [Abstract]
Convertible Unsecured Notes	Note 9—Convertible Unsecured Notes Convertible Unsecured Notes payable consisted of the following as of September 30, 2016 (unaudited): Notes Debt Offering Costs Net September 1, 2016 $ 1,250,000 $ (553,000 ) $ (20,000 ) $ 677,000 Amortization of debt discount and deferred financing costs — 46,000 2,000 48,000 Ending balance—September 30, 2016 1,250,000 (507,000 ) (18,000 ) 725,000 Less: Current Portion $ (1,250,000 ) $ 507,000 $ 18,000 $ (725,000 ) Long Term Portion $ — $ — $ — $ — On September 1, 2016, we entered into a securities purchase agreement and related note agreements and warrant agreements whereby we issued the Convertible Unsecured Notes and detachable five-year warrants to purchase an aggregate of 124,999 shares of the Company’s common stock at an exercise price of $4.00 per share (the “September 2016 Financing”). The Company received total gross proceeds of $1,250,000, less transaction expenses of $20,000 consisting of legal costs for net proceeds of $1,230,000. The Convertible Unsecured Notes bear interest at a rate of 12% per annum and mature on September 1, 2017. The Convertible Unsecured Notes are subordinate to the 2015 Notes described in Note 8. The Convertible Unsecured Notes are convertible at the option of the holder into common stock at an initial exercise price of $4.31 and will automatically convert into shares of common stock in the event of a conversion of at least 50% of the then outstanding (i) principal, (ii) accrued and unpaid interest with respect to such principal and (iii) accrued and unpaid late charges, if any, with respect to such principal and interest, under the 2015 Notes. Upon the conversion of 50% or more of the 2015 Notes at a price per share less than $4.31, the conversion price of the Convertible Unsecured Notes will be reduced to the effective conversion price of the 2015 Notes. The Convertible Unsecured Notes also contain a blocker provision that prevents the Company from effecting a conversion in the event that the holder, together with certain affiliated parties, would beneficially own in excess of 9.99% of the shares of common stock outstanding immediately after giving effect to such conversion. At any time after the issuance date of the Convertible Unsecured Notes, the Company may, at its option, redeem all or any portion of the then outstanding principal and accrued and unpaid interest with respect to such principal (the “Company Optional Redemption Amount”), at 100% of such aggregate amount; provided, however, that the Company may not redeem all or any portion of the Company Optional Redemption Amount so long as any of the 2015 Notes remain outstanding without the prior written consent of the collateral agent with respect to such 2015 Notes and certain investors holding the requisite number of conversion shares and warrant shares underlying the 2015 Notes and April and May Warrants. The Company evaluated the accounting of the detachable warrants and determined that the warrants should not be accounted for as derivative liabilities. The Company valued the warrants using the Black-Scholes Option pricing model at $271,000. The Company evaluated the conversion feature and determined that it should be accounted for as a derivative liability due to the potential variability of the conversion feature which is linked to the conversion of the Convertible 2015 Notes Payable. The conversion feature was valued using the Black-Scholes Option pricing model at $282,000 and will be marked to market each reporting period beginning with the quarter ending September 30, 2016. See also the discussion of derivative liabilities in Note 8 above. The securities purchase agreement calls for the issuance of additional five-year warrants to purchase an aggregate of 62,500 shares at an exercise price of $4.00 per share on each of the 61st, 91st, 121st and 151st days after the closing of the September 2016 Financing (each, an “Additional Warrant Date”), but only in the event the Company has not consummated a further financing consisting of the issuance of common stock and warrants for aggregate gross proceeds of at least $3,000,000 prior to such respective Additional Warrant Date.

Fair Value Measurements and Disclosures [Abstract]
Fair Value Measurements and Disclosures	Note 10—Fair Value Measurements and Disclosures Fair value is defined as the price that would be received upon sale of an asset or paid upon transfer of a liability in an orderly transaction between market participants at the measurement date and in the principal or most advantageous market for that asset or liability. The fair value should be calculated based on assumptions that market participants would use in pricing the asset or liability, not on assumptions specific to the entity. In addition, the fair value of liabilities should include consideration of non-performance risk, including the Company's own credit risk. Inputs used in measuring fair value are prioritized into a three-level hierarchy based on whether the inputs to those measurements are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company's market assumptions. The fair-value hierarchy requires the use of observable market data when available and consists of the following levels: ● Level 1—Quoted prices for identical instruments in active markets; ● Level 2—Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs are observable in active markets; and ● Level 3—Valuations derived from valuation techniques in which one or more significant inputs are unobservable.

Equity [Abstract]
Equity	Note 12—Equity On April 2, 2015, the Company entered into exchange agreements with the holders of all of the warrants issued in connection with the convertible notes offering in April 2014. As of March 31, 2015, the warrants were carried as derivative liabilities. On April 16, 2015, the exchange transaction was completed, with the Company issuing 73,747 shares of common stock (the “Exchange Shares”) in exchange for the return and cancellation of all of the warrants exercisable for up to an aggregate 81,942 shares of the common stock. The Exchange Shares were subject to a lock-up agreement that prohibited any sale or transfer (subject to certain limited exceptions) of the Exchange Shares until the earlier of June 1, 2015 or the first date that the weighted average price of the common stock equaled or exceeded $0.30 (as adjusted for any stock split, stock dividend, stock combination, reclassification or similar transaction occurring after the closing of the exchange transaction) for each of ten (10) consecutive trading days. The value of the Exchange Shares issued on the date of the exchange was $885,000. Prior to the exchange, we marked the warrants to market and recorded an additional loss on adjustment of derivative liabilities to reflect the market value of the warrants as of the date of the exchange. The $279,000 difference between the market value of the shares issued, valued at the closing market price on April 2, 2015, and the value of the warrants was recorded as a loss on exchange of warrants, represented in other expense on the consolidated statement of operations. In May 2015, we issued 108,000 shares of common stock to 30 accredited investors and received gross proceeds of $810,000 in cash. We paid placement fees and legal costs of $70,000 in cash, and we issued warrants to purchase 5,514 shares of the Company at an exercise price of $12.50 per share to the placement agent. The warrants expire in May 2020. In December 2015, we issued 312,500 units to 11 accredited investors and received gross proceeds of $2,500,000 in cash. Each unit consisted of two shares of common stock and one five year warrant to purchase one share of common stock at an exercise price of $5.00 per share. If the Company issues additional shares of common stock at a price per share less than $4.00, the investors have certain rights to receive additional shares of common stock and to have their warrant exercise price reduced. This right terminates at the earlier of six months from the December 31, 2015 issuance date or 30 days after the effectiveness of a registration statement for the resale of all common stock issued and underlying the warrants issued in the December 2015 offering. We paid placement fees and legal costs of $115,000 in cash for this transaction. We evaluated the warrants issued with the price reset right provisions and determined that the warrants should be recorded as a derivative liability. We recorded the fair value of the warrants issued as a derivative liability with a corresponding decrease in additional paid in capital. The warrants were valued using the Black-Scholes option pricing model at $1,115,000 on the issuance date and recorded as a derivative liability and a reduction in paid in capital. After the price reset provisions lapse, the fair value of the warrants, marked to market value on the date of the provision lapse, will be adjusted to additional paid in capital. Reverse Stock Split The board of directors of the Company approved the Reverse Stock Split, at a ratio of 1-for-50, effective as of the Effective Date. As a result of the Reverse Stock Split, the authorized preferred stock decreased to 1,000,000 shares and the authorized common stock decreased to 4,000,000 shares. Both the preferred stock and the common stock par value remained at $0.0001 per share. On September 3, 2015, as a result of the Company’s adoption of a new certificate of incorporation in conjunction with its conversion to a Delaware corporation, the authorized preferred shares increased to 50,000,000 shares and the authorized common shares increased to 200,000,000 shares. On the Effective Date, the total number of shares of common stock held by each stockholder of the Company were converted automatically into the number of shares of common stock equal to: (i) the number of issued and outstanding shares of common stock held by each such stockholder immediately prior to the Reverse Stock Split divided by (ii) 50. The Company issued one whole share of the post-Reverse Stock Split common stock to any stockholder who otherwise would have received a fractional share as a result of the Reverse Stock Split, determined at the beneficial owner level by share certificate. As a result, no fractional shares were issued in connection with the Reverse Stock Split and no cash or other consideration will be paid in connection with any fractional shares that would otherwise have resulted from the Reverse Stock Split. The Reverse Stock Split also affected all outstanding options and warrants by dividing each option or warrant outstanding by 50, rounded up to the nearest option or warrant, and multiplying the exercise price by 50 for each option or warrant outstanding. The number of shares of common stock outstanding immediately prior to the Reverse Stock Split was 123,193,755, and on the Effective Date, there were 2,463,919 shares of common stock outstanding. On July 15, 2015, the Company issued 241 additional shares of common stock to reflect the rounding up of fractional shares outstanding on the Effective Date. The number of shares underlying outstanding warrants and options immediately prior to the Reverse Stock Split was 16,951,674 and 15,423,051, respectively, and the number of shares underlying outstanding warrants and options after the Reverse Stock Split was 339,043 and 308,464, respectively. As a result of the Reverse Stock Split, the weighted average exercise price of the outstanding warrants increased from $0.36 per share to $17.81 per share and the weighted average exercise price of the outstanding options increased from $0.27 per share to $13.61 per share.

Stock Options and Warrants [Abstract]
Stock Options and Warrants	Note 12—Equity, Stock Options and Warrants On April 11, 2016, we entered into a stock purchase agreement dated April 11, 2016, pursuant to which we issued to an accredited investor an aggregate of 696,056 shares of our common stock in exchange for gross proceeds of approximately $3.0 million (the “April 2016 Private Placement”). The closing of the April 2016 Private Placement satisfied the Qualified Private Offering requirement in the March Amendments described below under “March 2016 Amendment to 2015 Notes”. Stock Options On July 1, 2013, our board of directors adopted and approved the 2013 Equity Incentive Plan (the “2013 Plan”) and amended the 2013 Plan on March 24, 2015 to increase the number of shares available for issuance. The 2013 Plan authorizes us to grant non-qualified stock options and restricted stock purchase rights to purchase up to 420,000 shares of our common stock with vesting to employees (including officers) and other service providers. With the approval of the 2015 Plan, described below, as of August 29, 2015, no shares of our common stock were available for issuance under the 2013 Plan. On July 15, 2015, our board of directors approved the 2015 Omnibus Incentive Plan (the “2015 Plan”), which was approved by our stockholders on August 28, 2015. Upon adoption, the 2015 Plan authorized us to grant up to 300,000 shares of our common stock and replaced the 2013 Equity Incentive Plan. As a result of the approval of the 2015 Plan, no additional grants will be made under the 2013 Plan. On August 22, 2016, our board of directors approved an amendment to the 2015 Plan to increase the total authorized pool available under the 2015 Plan to 600,000 shares of our common stock, subject to automatic increase for any shares subject to outstanding awards under the 2013 Plan that are subsequently canceled or expire. Our stockholders approved the foregoing amendment on September 26, 2016. As of September 30, 2016 594,000 shares of our common stock were available for issuance under the 2015 Plan. The 2015 Plan permits the granting of any or all of the following types of awards: incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock, restricted stock units, other stock-based awards, and performance awards payable in a combination of cash and company shares. There were no awards granted under the 2015 Plan as of September 30, 2016. The 2015 Plan has the following limitations: ● Limitation on terms of stock options and stock appreciation rights ● No repricing or grant of discounted stock options ● Clawback ● Double-trigger acceleration ● Code Section 162(m) Eligibility ● Dividends At September 30, 2016, total unrecognized deferred stock compensation expected to be recognized over the remaining weighted-average vesting periods of 0.6 years for outstanding grants was $1.0 million. The fair value of option awards is estimated on the grant date using the Black-Scholes option valuation model. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by employees who receive equity awards, and subsequent events are not indicative of the reasonableness of the original estimates of fair value made by us. Stock-based compensation expense is recorded only for those awards expected to vest. Currently, the forfeiture rate used to calculate stock-based compensation expense is zero which approximates the effective actual forfeiture rate. The rate is adjusted if actual forfeitures differ from the estimates in order to recognize compensation cost only for those awards that actually vest. If factors change and different assumptions are employed in future periods, the share-based compensation expense may differ from that recognized in previous periods. Stock-based award activity was as follows: Weighted- Weighted- Average Average Remaining Aggregate Exercise Contractual Intrinsic Options Price Life Value Balance, December 31, 2015 308,464 $ 13.61 6.07 $ — Forfeited during 2016 (40,914 ) 11.69 — — Granted during 2016 6,000 4.31 9.75 — Balance, September 30, 2016 273,550 $ 13.70 5.27 $ — Exercisable on September 30, 2016 192,394 $ 15.00 5.19 $ — The options granted have a contract term ranging between three and ten years. Options granted typically vest over a four year period, with 25% vesting after one year and the remainder ratably over the remaining three years. Of our options outstanding, 267,550 were outstanding and 192,394 exercisable under the 2013 Plan and 6,000 were outstanding with none exercisable under the 2015 Plan on September 30, 2016. The following table summarizes information about stock options outstanding and exercisable at September 30, 2016: Options Outstanding Options Exercisable Weighted- Average Weighted- Weighted- Number Remaining Average Number Average Exercise of Contractual Exercise of Exercise Prices Shares Life Price Shares Price (In years) $0–$10.00 99,840 7.04 $ 7.46 50,771 $ 7.68 $10.01–$15.00 31,100 7.16 $ 12.50 18,730 $ 12.50 $15.01–$20.00 122,766 3.50 $ 17.50 104,381 $ 17.50 $20.01–$25.00 19,844 4.30 $ 23.40 18,512 $ 23.58 273,550 5.27 $ 13.70 192,394 $ 15.00 Stock based compensation expense consisted of the following: Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 2016 2015 Research and development $ 113,000 $ 148,000 $ 423,000 $ 443,000 General and administrative 187,000 224,000 604,000 670,000 $ 300,000 $ 372,000 $ 1,027,000 $ 1,113,000 Warrants From time to time, we issue warrants to purchase shares of our common stock to investors, note holders and to non-employees for services rendered or to be rendered in the future. February 2016 Additional Warrants On February 2, 2016, the Company issued Additional Warrants to purchase an aggregate of 50,000 shares of the Company’s common stock to existing noteholders under the terms of the December Amendments. March 2016 Amendment to 2015 Notes On March 31, 2016, the Company executed the March Amendments with certain investors holding the requisite number of conversion shares and warrant shares underlying the 2015 Notes and April and May Warrants pursuant to the related Securities Purchase Agreements. The March Amendments, described above in Note 8, provided for the issuance of the March Warrants, exercisable for ten shares of the Company’s common stock per $100 of outstanding principal of the 2015 Notes held by each buyer pursuant to the April 2015 and May 2015 Securities Purchase Agreements, each with an exercise price of $5.00 per share, subject to adjustment as set forth within the warrants. March Warrants to purchase an aggregate of 500,000 shares of the Company’s common stock were issued to the holders of the 2015 Notes on March 31, 2016. On August 24, 2016, the March Warrants were amended to reduce the exercise price to $4.00 per share, as described below. August 2016 Warrant Amendments On August 24, 2016 the Company executed amendments to the April and May Warrants, December Warrants, December Offering Warrants, February Warrants and March Warrants, as indicated in the table below. The amendments reduced the exercise price of the warrants to $4.00 per share and removed all remaining net cash settlement provisions in each warrant. For the warrants accounted for as derivative liabilities, the Company marked the warrants to market immediately prior to the change in the strike price to a value of $1,719,000. The removal of the warrant agreement provisions that required derivative accounting resulted in a reclassification of $1,719,000 from derivative liabilities to Paid-in Capital. The reduction in exercise price to $4.00 resulted in an additional discount to the 2015 Notes of $206,000 which will be amortized to interest expense over the expected remaining life of the 2015 Notes. Warrants outstanding as of September 30, 2016 consist of: Issue Expiry Number of Exercise Price 2013 Services Warrants—July Jul-13 Jul-18 9,494 $ 37.50 2013 Services Warrants—August Aug-13 Aug-18 729 37.50 2013 Services Warrants—November Nov-13 Nov-18 2,400 50.00 2014 Services Warrants—April(1) Apr-14 Apr-19 13,657 39.00 2014 Services Warrants—September(2) Aug-14 Aug-19 16,000 25.00 2014 PIPE Warrants—September(3) Sept-14 Sept-18 26,500 25.00 2014 Services Warrants—November(4) Nov-14 Nov-18 6,500 25.00 2014 Settlement Warrants—December(5) Dec-14 Dec-19 38,464 25.00 2015 Notes Warrants(6) (14) Apr/May-15 Apr/May-20 219,785 4.00 2015 Services Warrants—May(7) May-15 May-20 5,514 12.50 2015 LOC Guarantee Warrants—November (8) Nov-15 Nov-20 74,000 15.00 2015 Debt Amendment Warrants—December (9), (15) Dec-15 Dec-20 50,000 4.00 2015 PIPE Warrants—December (10), (15) Dec-15 Dec-20 312,500 4.00 2016 Debt Amendment Warrants—February (11), (15) Feb-16 Feb-21 50,000 4.00 2016 Debt Amendment Warrants—March (12), (15) Mar-16 Mar-21 500,000 4.00 2016 Junior Debt Warrants (13) Sep-16 Aug-21 124,999 4.00 Balance outstanding at September 30, 2016 1,450,542 $ 6.50 Warrants exercisable at September 30, 2016 1,376,542 $ 6.04 (1) The 2014 Services Warrants—April were issued for fees incurred in conjunction with the issuance of convertible notes in 2014.

On September 22, 2014, the exercise price was changed to $25.00 per share. There are no further exercise price changes for this warrant series. The warrants were valued using the Black-Scholes option pricing model at $131,000 on the issuance date with an additional $6,000 recorded to expense on September 22, 2014 to reflect the change in fair value resulting from the exercise price change.

The warrants issued on December 1, 2014 were issued concurrent with the issuance of 8,462 shares of the Company’s common stock in partial settlement of the potential legal disputes arising from claims by two investors. The Company settled all remaining potential legal disputes with all of the remaining investors in the November 2013 private placement on December 15, 2014 by issuing the second tranche of warrants and setting the exercise price of each warrant series issued at $25.00 with no further reset provisions.

Note 13—Stock Options and Warrants Stock options On July 1, 2013, our board of directors adopted and approved the 2013 Equity Incentive Plan (the “2013 Plan”) and amended the 2013 Plan on March 24, 2015 to increase the number of shares available for issuance. The 2013 Plan authorizes us to grant non-qualified stock options and restricted stock purchase rights to purchase up to 420,000 shares of our common stock with vesting to employees (including officers) and other service providers. With the approval of the 2015 Plan described below, as of August 29, 2015, no shares of our common stock were available for issuance under the 2013 Plan. On July 15, 2015, our board of directors approved the 2015 Omnibus Incentive Plan (the “2015 Plan”), which was approved by our stockholders on August 28, 2015. The 2015 Plan authorizes us to grant up to 300,000 shares of our common stock and is intended to replace the 2013 Equity Incentive Plan. If the 2015 Plan is approved by our stockholders, no additional grants will be made under the 2013 Plan. The 2015 Plan permits the granting of any or all of the following types of awards: incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock, restricted stock units, other stock-based awards, and performance awards payable in a combination of cash and company shares. There were no awards granted under the 2015 plan as of December 31, 2015. The 2015 Plan has the following limitations: ● Limitation on terms of stock options and stock appreciation rights ● No repricing or grant of discounted stock options ● Clawback ● Double-trigger acceleration ● Code Section 162(m) Eligibility ● Dividends At December 31, 2015, total unrecognized deferred stock compensation expected to be recognized over the remaining weighted-average vesting periods of 1.0 years for outstanding grants was $2.2 million. The fair value of option awards is estimated on the grant date using the Black-Scholes option valuation model. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by employees who receive equity awards, and subsequent events are not indicative of the reasonableness of the original estimates of fair value made by us. The following table presents the weighted-average grant date assumptions used to estimate the fair value of options and stock appreciation rights granted. December 31, 2015 Expected volatility 100-150 % Dividend yield 0.00 % Risk-free interest rate 1.10–2.15 % Expected life (in years) 3.0-6.8 Expected volatility represents the estimated volatility of the shares over the expected life of the options. We have estimated the expected volatility based on the weighted-average historical volatilities of a pool of public companies that are comparable to Ener-Core. We use an expected dividend yield of zero since no dividends are expected to be paid. The risk-free interest rate for periods within the expected life of the option is derived from the U.S. treasury interest rates in effect at the date of grant. The expected option life represents the period of time the option is expected to be outstanding. The simplified method is used to estimate the term since we do not have sufficient exercise history to calculate the expected life of the options. Stock-based compensation expense is recorded only for those awards expected to vest. Currently, the forfeiture rate is zero. The rate is adjusted if actual forfeitures differ from the estimates in order to recognize compensation cost only for those awards that actually vest. If factors change and different assumptions are employed in future periods, the share-based compensation expense may differ from that recognized in previous periods. Stock-based award activity was as follows: Weighted- Weighted- Average Average Remaining Aggregate Exercise Contractual Intrinsic Options Price Life Value Balance, December 31, 2014 267,257 $ 15.00 6.51 $ 47,000 Forfeited during 2015 (21,033 ) 17.00 — — Granted during 2015 62,240 8.30 — — Balance, December 31, 2015 308,464 $ 13.61 6.07 $ — Exercisable on December 31, 2015 151,576 $ 15.38 5.38 $ — The options granted have a contract term ranging between three and ten years. Options granted typically vest over a four year period, with 25% vesting after one year and the remainder ratably over the remaining three years.

The warrants were originally issued at $39.00 per share and had a one-time price reset provision to the exercise price of the warrants issued to investors in the convertible notes offering in April 2014 if the exercise price of such convertible notes warrants changed prior to September 30, 2014. On September 22, 2014, the exercise price was changed to $25.00 per share. There are no further exercise price changes for this warrant series. The warrants were valued using the Black-Scholes option pricing model at $131,000 on the issuance date with an additional $6,000 recorded to expense on September 22, 2014 to reflect the change in fair value resulting from the exercise price change.

The warrants issued on December 1, 2014 were issued concurrent with the issuance of 8,462 shares of the Company’s common stock in partial settlement of the potential legal disputes arising from claims by two investors. The Company settled all remaining potential legal disputes with all of the remaining investors in the November 2013 private placement on December 15, 2014 by issuing the second tranche of warrants and setting the exercise price of each warrant series issued at $25.00 with no further reset provisions.

The warrants were valued using the Black-Scholes option pricing model at $182,000 on the issuance date and were recorded as a derivative liability and additional debt discount. In the event that the Company issues additional common stock derivative securities at a price per share less than the exercise price, the Company is obligated to reduce the exercise price of the December Debt Amendment Warrants to a price per share equal to the newly issued shares or derivative common stock securities.

Income Taxes [Abstract]
Income Taxes	Note 14—Income Taxes Income tax provision for the year ended December 31, 2015 and the year ended December 31, 2014 consists of the following: Year Ended December 31, Year Ended December 31, Current income tax expense: Federal $ — $ — State 1,000 1,000 Total $ 1,000 $ 1,000 Deferred income tax expense: Federal — — State — — Total $ — $ — Provision for income taxes $ 1,000 $ 1,000 Due to net losses, effective tax rate for the periods presented was 0%. Deferred income tax assets and liabilities are recorded for differences between the financial statement and tax basis of the assets and liabilities that will result in taxable or deductible amounts in the future based on enacted laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. The valuation allowance increased by $ 4.8 million from December 31, 2014 to December 31, 2015. December 31, December 31, Deferred tax assets: Net operating loss carry-forward $ 13,070,000 8,276,000 Valuation allowance (13,070,000 ) (8,276,000 ) Net deferred tax assets $ — $ — A significant component of our deferred tax assets consisted of net operating loss carry-forwards. We have evaluated the available evidence supporting the realization of our deferred tax assets, including the amount and timing of future taxable income, and have determined it is more likely than not that the assets will not be fully realized and a full valuation allowance is necessary as of December 31, 2015 and 2014. As of December 31, 2015, we have federal and state net operating loss carry-forwards of approximately $21.6 million and $21 million, respectively, which expire through 2032. The utilization of net operating loss carry-forwards may be subject to limitations under provision of the Internal Revenue Code Section 382 and similar state provisions. We follow ASC 740 related to accounting for uncertain tax positions, which prescribes a recognition threshold and measurement process for recording in the financial statements, uncertain tax positions taken or expected to be taken in a tax return. Under this provision, the impact of an uncertain income tax position on the income tax return must be recognized at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant taxing authority. Tax benefits of an uncertain tax position will not be recognized if it has less than a 50% likelihood of being sustained based on technical merits. We did not have any uncertain income tax position as of December 31, 2015 and 2014.

Accounts Receivable	Accounts Receivable Our accounts receivable are typically from credit worthy customers or, for international customers are supported by guarantees or letters of credit. For those customers to whom we extend credit, we perform periodic evaluations of them and maintain allowances for potential credit losses as deemed necessary. We generally do not require collateral to secure accounts receivable. We have a policy of reserving for uncollectible accounts based on our best estimate of the amount of probable credit losses in existing accounts receivable. We periodically review our accounts receivable to determine whether an allowance is necessary based on an analysis of past due accounts and other factors that may indicate that the realization of an account may be in doubt. Account balances deemed to be uncollectible are charged to the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. As of September 30, 2016, one customer accounted for all of our accounts receivable.

As of December 31, 2015 and December 31, 2014, two customers and one customer, respectively, accounted for 100% of net accounts receivable.
Accounts Payable	Accounts Payable As of September 30, 2016 and December 31, 2015, three and five vendors, respectively, collectively accounted for approximately 45% and 50% of our total accounts payable.	Accounts Payable As of December 31, 2015 and December 31, 2014, five and six vendors, respectively, collectively accounted for approximately 50% and 54% of our total accounts payable.
Inventory	Inventory Inventory, which consists of raw materials inventory consisting of Power Oxidizer parts and sub-assemblies of parts recorded as work-in-progress inventory, is stated at the lower of cost or net realizable value, with cost being determined by the average-cost method, which approximates the first-in, first-out method. At each balance sheet date, we evaluate our ending inventory for excess quantities and obsolescence. This evaluation primarily includes an analysis of forecasted demand in relation to the inventory on hand, among consideration of other factors. Based upon the evaluation, provisions are made to reduce excess or obsolete inventories to their estimated net realizable values. Once established, write-downs are considered permanent adjustments to the cost basis of the respective inventories. At September 30, 2016 and December 31, 2015, we did not have a reserve for slow-moving or obsolete inventory.

Property and Equipment	Property and Equipment Property and equipment are stated at cost, and are being depreciated using the straight-line method over the estimated useful lives of the related assets, ranging from three to ten years. Maintenance and repairs that do not improve or extend the lives of the respective assets are expensed. At the time property and equipment are retired or otherwise disposed of, the cost and related accumulated depreciation accounts are relieved of the applicable amounts. Gains or losses from retirements or sales are reflected in the consolidated statements of operations.

Accrued Warranties	Accrued Warranties Accrued warranties represent the estimated costs that will be incurred during the warranty period of our products. We make an estimate of expected costs that will be incurred by us during the warranty period and charge that expense to the consolidated statement of operations at the date of sale. We also reevaluate the estimate at each balance sheet date and if the estimate is changed, the effect is reflected in the consolidated statement of operations. We had no warranty accrual at December 31, 2015 or September 30, 2016. We expect that most terms for future warranties of our Powerstations and Oxidizers will be one to two years depending on the warranties provided and the products sold. Accrued warranties for expected expenditures within one year are classified as current liabilities and as non-current liabilities for expected expenditures for time periods beyond one year.

We made our initial commercial sale to Efficient Energy Conversion TurboMachinery, B.V. (“EECT”) in the second quarter of 2014 with a six month warranty and later extended that warranty at our discretion. There was no warranty for the unit shipped to the Fort Benning site. We expect that most terms our future warranty period to be one to two years depending on the warranties provided and the products sold. Accrued warranties for expected expenditures within the next year are classified as current liabilities and as non-current liabilities for expected expenditures for time periods beyond one year.
Deferred Rent	Deferred Rent We record deferred rent expense, included in accrued expenses, which represents the temporary differences between the reporting of rental expense on the financial statements and the actual amounts remitted to the landlord. The deferred rent portion of lease agreements are leasing inducements provided by the landlord. Also, tenant improvement allowances provided are recorded as a deferred rent liability and recognized ratably as a reduction to rent expense over the lease term. As of September 30, 2016 we had $4,000 of deferred rent, recorded in accrued expenses.

We amortize our intangible assets with finite lives over their estimated useful lives.	Intangible Assets Our intangible assets represent intellectual property acquired during the reverse merger. We amortize our intangible assets with finite lives over their estimated useful lives.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets We account for our long-lived assets in accordance with the accounting standards which require that long-lived assets be reviewed for impairment whenever events or changes in circumstances indicate that the historical carrying value of an asset may no longer be appropriate. We consider the carrying value of assets may not be recoverable based upon its review of the following events or changes in circumstances: the asset’s ability to continue to generate income from operations and positive cash flow in future periods; loss of legal ownership or title to the assets; significant changes in our strategic business objectives and utilization of the asset; or significant negative industry or economic trends. An impairment loss would be recognized when estimated future cash flows expected to result from the use of the asset are less than its carrying amount. As of September 30, 2016 and December 31, 2015, we do not believe there have been any impairments of our long-lived assets. There can be no assurance, however, that market conditions will not change or demand for our products will continue, which could result in impairment of long-lived assets in the future.

Fair Value of Financial Instruments	Fair Value of Financial Instruments Our financial instruments consist primarily of cash and cash equivalents, restricted cash, accounts receivable, accounts payable, convertible notes, derivative liabilities, and capital lease liabilities. Fair value estimates discussed herein are based upon certain market assumptions and pertinent information available to management as of September 30, 2016 and December 31, 2015. The carrying amounts of short-term financial instruments are reasonable estimates of their fair values due to their short-term nature or proximity to market rates for similar items. We determine the fair value of our financial instruments based on a three-level hierarchy established for fair value measurements under which these assets and liabilities must be grouped, based on significant levels of observable or unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect management’s market assumptions. This hierarchy requires the use of observable market data when available. These two types of inputs have created the following fair-value hierarchy: ● Level 1: Valuations based on unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Currently, we classify our cash and cash equivalents as Level 1 financial instruments. ● Level 2: Valuations based on observable inputs (other than Level 1 prices), such as quoted prices for similar assets at the measurement date quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability. We do not currently have any accounts under Level 2. ● Level 3: Valuations based on inputs that require inputs that are both significant to the fair value measurement and unobservable and involve management judgment (i.e., supported by little or no market activity). Currently, we classify our warrants and conversion options accounted for as derivative liabilities as Level 3 financial instruments. If the inputs used to measure fair value fall in different levels of the fair value hierarchy, a financial security’s hierarchy level is based upon the lowest level of input that is significant to the fair value measurement.

Derivative Financial Instruments	Derivative Financial Instruments We issue derivative financial instruments in conjunction with its debt and equity offerings and to provide additional incentive to investors and placement agents. The Company uses derivative financial instruments in order to obtain the lowest cash cost-source of funds. Derivative liabilities are recognized in the consolidated balance sheets at fair value based on the criteria specified in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) topic 815-40 “ Derivatives and Hedging—Contracts in Entity’s own Equity The Company issued detachable common stock warrants and secured debt with a conversion feature in April and May 2015 and again in September 2016. We amended our existing debt to add a conversion feature in December 2015. The Company issued additional common stock warrants with price reset provisions in December 2015, February 2016, and March 2016. These embedded derivatives and detachable warrants were evaluated under ASC topic 815-40. We determined that the warrants and embedded conversion feature for the April 2014 issuance, the conversion feature for the 2015 issuances, the conversion feature for the 2016 issuance, and the warrants issued with price reset provisions should be accounted for as derivative liabilities. In August, 2016 all warrants issued that were previously determined to be accounted for as derivative liabilities were amended and we determined that after giving rise to the amendments, that the warrants were no longer required to be accounted for as derivative liabilities. We determined that the detachable warrants associated with the 2015 issuance on the issuance date and the detachable warrants associated with the 2016 issuance on the issuance date should not be accounted for as derivative liabilities. Warrants and the debt conversion features determined to be derivative liabilities were bifurcated from the debt host and are classified as liabilities on the consolidated balance sheet. Warrants not determined to be derivative liabilities were recorded to debt discount and paid-in capital. The Company records the warrants and embedded derivative liabilities at fair value and adjusts the carrying value of the common stock warrants and embedded derivatives to their estimated fair value at each reporting date with the increases or decreases in the fair value of such warrants and derivatives at each reporting date, recorded as a gain or (loss) in the consolidated statements of operations. The 2015 detachable warrants determined not to be derivative liabilities were recorded to debt discount with a corresponding entry to paid-in capital. The warrants amended in 2016 where the accounting was changed to eliminate derivative liability treatment were marked to market immediately prior to the amendment and the fair value was reclassified on the amendment date from derivative liabilities to paid in capital.

Revenue Recognition	Revenue Recognition We generate revenue from the sale of our clean power energy systems and from consulting services. Revenue is recognized when there is persuasive evidence of an arrangement, product delivery and acceptance have occurred, the sales price is fixed or determinable and collectability of the resulting receivable is reasonable assured. Amounts billed to clients for shipping and handling are classified as sales of product with related costs incurred included in cost of sales. Provisions for discounts and rebates to customers, estimated returns and allowances, and other adjustments are provided for in the same period the related revenue is recorded. We defer any revenue for which the services have not been performed or are subject to refund until such time that we and our customer jointly determine that the services have been performed or no refund will be required. Revenues under long-term construction contracts are generally recognized using the completed-contract method of accounting. Long-term construction-type contracts for which reasonably dependable estimates cannot be made or for which inherent hazards make estimates difficult are accounted for under the completed-contract method. Revenues under the completed-contract method are recognized upon substantial completion—that is acceptance by the customer, compliance with performance specifications demonstrated in a factory acceptance test or similar event. Accordingly, during the period of contract performance, billings and costs are accumulated on the balance sheet, but no profit or income is recorded before completion or substantial completion of the work. Anticipated losses on contracts are recognized in full in the period in which losses become probable and estimable. Changes in estimate of profit or loss on contracts are included in earnings on a cumulative basis in the period the estimate is changed. As of September 30, 2016 and December 31, 2015, we had a $600,000 provision for contract losses for both periods presented.

Research and Development Costs	Research and Development Costs Research and development costs are expensed as incurred. Research and development costs were $1,170,000 and $928,000 for the three months ended September 30, 2016 and 2015, respectively, and were $2,871,000 and $2,636,000 for the nine months ended September 30, 2016 and 2015, respectively.	Research and Development Costs Research and development costs are expensed as incurred. Research and development costs were $3,412,000 and $3,156,000 for the years ended December 31, 2015 and 2014, respectively.
Share-Based Compensation	Share-Based Compensation We maintain an equity incentive plan and record expenses attributable to the awards granted under the equity incentive plan. We amortize share-based compensation from the date of grant on a weighted average basis over the requisite service (vesting) period for the entire award. We account for equity instruments issued to consultants and vendors in exchange for goods and services at fair value. The measurement date for the fair value of the equity instruments issued is determined at the earlier of (i) the date at which a commitment for performance by the consultant or vendor is reached or (ii) the date at which the consultant’s or vendor’s performance is complete. In the case of equity instruments issued to consultants, the fair value of the equity instrument is recognized over the term of the consulting agreement. In accordance with the accounting standards, an asset acquired in exchange for the issuance of fully vested, non-forfeitable equity instruments should not be presented or classified as an offset to equity on the grantor’s balance sheet once the equity instrument is granted for accounting purposes. Accordingly, we record the fair value of the fully vested, non-forfeitable common stock issued for future consulting services as prepaid expense in our consolidated balance sheets.

Income taxes	Income Taxes We account for income taxes under FASB ASC 740 “Income Taxes.” Under the asset and liability method of FASB ASC 740, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Under FASB ASC 740, the effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period the enactment occurs. A valuation allowance is provided for certain deferred tax assets if it is more likely than not that we will not realize tax assets through future operations.	Income Taxes We account for income taxes under the provisions of the accounting standards. Under the accounting standards, deferred tax assets and liabilities are recognized for the expected future tax benefits or consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. A valuation allowance is provided for significant deferred tax assets when it is more likely than not that such asset will not be realized through future operations. Our deferred tax assets and liabilities are primarily related to our Net Operating Losses and timing differences between book and tax accounting for depreciation and our net deferred tax assets were fully reserved as of December 31, 2015 and December 31, 2014. The accounting guidance for uncertainty in income taxes provides that a tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits. We recognize any uncertain income tax positions on income tax returns at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. As of December 31, 2015 and 2014 and there were no unrecognized tax benefits included in the consolidated balance sheets that would, if recognized, affect the effective tax rate. Our practice is to recognize interest and/or penalties related to income tax matters in income tax expense. We had no accrual for interest or penalties on our consolidated balance sheets at December 31, 2015 and 2014 and have not recognized interest and/or penalties in the consolidated statements of operations for the years ended December 31, 2015 or 2014. We are subject to taxation in the U.S. and various state and foreign jurisdictions. We do not foresee material changes to our gross uncertain income tax position liability within the next twelve months.
Earnings (Loss) per Share	Earnings (Loss) per Share Basic loss per share is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares assumed to be outstanding during the period of computation. Diluted loss per share is computed similar to basic loss per share except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potential shares had been issued and if the additional common shares were dilutive. The following approximate share amounts were excluded from the computation of diluted loss per share due to the anti-dilutive effect on net loss per share: September 30, September 30, Shares issuable for exercise of options and warrants 1,600,000 500,000 Full conversion of convertible senior secured and unsecured notes 1,500,000 — Total 3,100,000 500,000 All share and per share amounts in the table below have been adjusted to reflect the 1-for-50 reverse split of our issued and outstanding common stock on July 8, 2015, retroactively.

Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In May 2014, the FASB issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”). In April 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-10, Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing (“ASU 2016-10”). ASU 2014-09, with additional guidance and clarification from ASU 2016-10, provides a framework for addressing revenue recognition issues and, upon its effective date, replaces almost all existing revenue recognition guidance, including industry-specific guidance, in current U.S. generally accepted accounting principles. ASU 2016-10 provides additional guidance specific to licensing and royalty revenue recognition. ASU 2014-09 is effective beginning with the calendar year ended December 31, 2017. The Company has not yet assessed the impact ASU 2014-09 will have upon adoption on its financial position, results of operations or cash flows. In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. ASU 2014-15 requires that an entity’s management evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. Substantial doubt about an entity’s ability to continue as a going concern exists when relevant conditions and events, considered in the aggregate, indicate that it is probable that the entity will be unable to meet its obligations as they become due within one year after the date that the financial statements are issued. Certain disclosures are necessary in the footnotes to the financial statements in the event that conditions or events raise substantial doubt about an entity’s ability to continue as a going concern. ASU 2014-15 is effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter and early application is permitted. The Company has not yet assessed the impact ASU 2014-15 will have upon adoption. In November 2014, the FASB issued ASU 2014-16—Derivatives and Hedging: Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share is More Akin to Debt or to Equity. ASU 2014-16 clarifies how current GAAP should be interpreted in evaluating the economic characteristics and risks of a host contract in a hybrid financial instrument that is issued in the form of a share. ASU 2014-16 became effective for the interim and annual periods beginning after December 15, 2015. There was no impact to any prior periods presented as a result of adopting ASU 2014-16. In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. ASU 2015-11 requires that entities measure inventory at the lower of cost and net realizable value. ASU 2015-11 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years and early application is permitted.

ASU 2014-15 requires that an entity’s management evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. Substantial doubt about an entity’s ability to continue as a going concern exists when relevant conditions and events, considered in the aggregate, indicate that it is probable that the entity will be unable to meet its obligations as they become due within one year after the date that the financial statements are issued. Certain disclosures are necessary in the footnotes to the financial statements in the event that conditions or events raise substantial doubt about an entity’s ability to continue as a going concern. ASU 2014-15 is effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter and early application is permitted.

In April 2015, the FASB issued ASU 2015-03, Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. ASU 2015-03 simplifies the presentation of debt issuance costs by requiring that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this update. ASU 2015-03 became effective for public business entities for financial statements issued for fiscal years beginning after December 15, 2015 and interim periods within those fiscal years and early application is permitted.
