Organization, Consolidation and Presentation of Financial Statements [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies (a) The Company and Nature of Operations FalconStor Software, Inc., a Delaware Corporation (the "Company" or "FalconStor"), is a leading storage software company offering a converged data services software platform that is hardware agnostic. The Company develops, manufactures and sells data migration, business continuity, disaster recovery, optimized backup and de-duplication solutions and provides the related maintenance, implementation and engineering services. (b) Liquidity As of December 31, 2018 , we had a working capital deficiency of $1.1 million , which is inclusive of current deferred revenue of $6.9 million , and a stockholders' deficit of $11.6 million . During the year ended December 31, 2018 , while we had net loss of $0.9 million and negative cash flow from operations of $1.5 million . Our cash and cash equivalents at December 31, 2018 was $3.1 million , an increase of $2.0 million as compared to December 31, 2017 . In June 2017, the Board approved a comprehensive plan to increase operating performance (the “2017 Plan”). The 2017 Plan resulted in a realignment in workforce. The 2017 Plan was substantially completed by the end of the Company’s fiscal year ending December 31, 2017, and when combined with previous workforce reductions in the second quarter of Fiscal 2017 reduced the Company’s workforce to approximately 81 employees. On November 17, 2017, HCP-FVA, LLC (the “Lender”) provided a commitment letter to the Company agreeing to finance up to $3 million to the Company (the “Commitment”) on the terms, and subject to the conditions, set forth in that certain commitment letter (see Note (7) Short-Term Loan and Commitment ). As part of that Commitment, on November 17, 2017, the Company entered into a Loan and Security Agreement (the “Loan Agreement”) with Lender and certain other loan parties named therein, pursuant to which the Lender made a short term loan to the Company in the principal amount of $500,000 (the “Short Term Loan”). On February 23, 2018, the Company closed on the Commitment and the Lender subscribed for the full $3 million of Units in the Commitment by payment of $2.5 million in cash and the conversion of the $500,000 Short Term Loan. The $3 million term loan has an interest rate of prime plus 0.75% and a maturity date of June 30, 2021. The Lender is an affiliate of Hale Capital Partners, LP (together, "Hale Capital") and the Company's largest shareholder through its ownership of Series A redeemable preferred stock ("Series A Preferred Stock"), and an affiliate of Martin Hale, a Director of the Company. As part of the Commitment, Hale Captial also agreed to postpone the date of the optional redemption of the Series A Preferred Stock from August 5, 2017 to July 30, 2021, and to waive prior breaches of the terms of the Series A Preferred Stock which had triggered a redemption right. On October 9, 2018, FalconStor closed on the final tranche of its previously-announced Financing of Units (see Note (7) Short-Term Loan and Commitment ) to certain eligible stockholders of the Company. As a result, the Company received an additional $1,000,000 of gross proceeds from new investors (the “New Investors”) which is in addition to the $3,000,000 of gross proceeds previously received from HCP-FVA through the subscription of 30,000,000 Units pursuant to the Commitment on February 23, 2018. In December 2018, outstanding Warrants to purchase 489,321,074 were exercised resulting in the issuance of 489,321,074 shares of Common Stock (the “Warrant Exercise”). In connection with the Warrant Exercise, the Company received proceeds of approximately $489,321 , which was used to reduce the outstanding principal due on Amended and Restated Loan Agreement. We believe that our cash flows from operations and existing cash on hand are sufficient to conduct our planned operations and meet our contractual requirements through April 2, 2020. (c) Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. (d) 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 revenues and expenses during the reporting period. The Company’s significant estimates include those related to revenue recognition, accounts receivable allowances, share-based payment compensation, valuation of derivatives, capitalizable software development costs, valuation of goodwill and other intangible assets and income taxes. Actual results could differ from those estimates. The financial market volatility in many countries where the Company operates has impacted and may continue to impact the Company’s business. Such conditions could have a material impact on the Company’s significant accounting estimates discussed above. (e) Fair Value of Financial Instruments Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. To increase the comparability of fair value measurements, a three-tier fair value hierarchy, which prioritizes the inputs used in the valuation methodologies, is as follows: Level 1 —Valuations based on quoted prices for identical assets and liabilities in active markets. Level 2 —Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3 —Valuations based on unobservable inputs reflecting our own assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment. As of December 31, 2018 and 2017 , the fair value of the Company’s financial instruments including cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximated carrying value due to the short maturity of these instruments. See Note ( 3 ) Fair Value Measurements for additional information. (f) Derivative Financial Instruments The Company does not use derivative instruments to hedge exposures to cash flow, market or foreign currency risk. Terms of convertible preferred stock are reviewed to determine whether or not they contain embedded derivative instruments that are required under Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 815 “Derivatives and Hedging” (“ASC 815”) to be accounted for separately from the host contract, and recorded on the balance sheet at fair value. The fair value of derivatives are required to be revalued at each reporting date, with corresponding changes in fair value recorded in current period operating results. See Note ( 12 ) Derivative Financial Instruments for additional information. (g) Revenue from Contracts with Customers and Associated Balances The Company derives its revenue from sales of its products, support and services. Product revenue consists of the Company’s software integrated with industry standard hardware and sold as complete turn-key integrated solutions, as stand-alone software applications or sold on a subscription or consumption basis. Depending on the nature of the arrangement revenue, related to turn-key solutions and stand-alone software applications are generally recognized upon shipment and delivery of license keys. For certain arrangements revenue is recognized based on usage or ratably over the term of the arrangement. Support and services revenue consists of both maintenance revenues and professional services revenues. Revenue is recorded net of applicable sales taxes. In accordance with the authoritative guidance issued by the FASB on revenue recognition, the Company recognizes revenue when persuasive evidence of an arrangement exists, the fee is fixed or determinable, delivery has occurred, and collection of the resulting receivable is deemed probable. Products delivered to a customer on a trial basis are not recognized as revenue until the trial period has ended and acceptance has occurred by the customer. Reseller and distributor customers typically send the Company a purchase order when they have an end user identified. Nature of Products and Services Licenses for on-premises software provide the customer with a right to use the software as it exists when made available to the customer. Customers may purchase perpetual licenses or subscribe to licenses, which provide customers with the same functionality and differ mainly in the duration over which the customer benefits from the software. Revenue from distinct on-premises licenses is recognized upfront at the point in time when the software is made available to the customer. Revenue allocated to software maintenance and support services is recognized ratably over the contractual support period. Hardware products consist primarily of servers and associated components and function independently of the software products and as such as accounted for as separate performance obligations. Revenue allocated to hardware maintenance and support services is recognized ratably over the contractual support period. Professional services are primarily related to software implementation services and associated revenue is recognized upon customer acceptance. Contract Balances Timing of revenue recognition may differ from the timing of invoicing to customers. The Company records a contract asset or receivable when revenue is recognized prior to invoicing, or unearned revenue when revenue is recognized subsequent to invoicing. For perpetual licenses with multi-year product maintenance agreements, the Company generally invoices customers at the beginning of the coverage period. For multi-year subscription licenses, the Company generally invoices customers annually at the beginning of each annual coverage period. The Company records a contract asset related to revenue recognized for multi-year on-premises licenses as its right to payment is conditioned upon providing product support and services in future years. The opening balance of accounts receivable, net of allowance for doubtful accounts, was $4.2 million as of January 1, 2018. There was no adjustment needed to accounts receivable for the cumulative effect of applying ASC 606 under the modified retrospective method. The opening balance of short and long-term contract assets, net of allowance for doubtful accounts, and adjusted for the cumulative effect of applying ASC 606 under the modified retrospective method, was $3.1 million as of January 1, 2018. As of December 31, 2018 and 2017, accounts receivable, net of allowance for doubtful accounts, was $3.6 million and $4.2 million , respectively. As of December 31, 2018 and 2017, short and long-term contract assets, net of allowance for doubtful accounts, was $1.2 million and $0.0 million , respectively. The allowances for doubtful accounts reflect the Company’s best estimates of probable losses inherent in the accounts receivable and contract assets’ balances. The Company determines the allowances based on known troubled accounts, historical experience, and other currently available evidence. Write-offs in the accounts receivable and contract assets allowance accounts during the years ended December 31, 2018 and 2017 were $0.1 million and $0.1 million , respectively. Deferred revenue is comprised mainly of unearned revenue related maintenance and technical support on term and perpetual licenses. Maintenance and technical support revenue is recognized ratably over the coverage period. Deferred revenue also includes contracts for professional services to be performed in the future which are recognized as revenue when the company delivers the related service pursuant to the terms of the customer arrangement. Changes in deferred revenue were as follows: Twelve Months Ended December 31, 2018 Balance at December 31, 2017 18,360,690 Cumulative effect of applying ASC 606 under the modified retrospective method* (5,359,579 ) Deferral of revenue 14,249,597 Recognition of revenue (17,837,906 ) Change in reserves (46,312 ) Balance at December 31, 2018 $ 9,366,490 *See Note (1) Summary of Significant Accounting Policies, section (s) to our Consolidated Financial Statements for further information. Deferred revenue includes invoiced revenue allocated to remaining performance obligations that has not yet been recognized and will be recognized as revenue in future periods. Deferred revenue was $9.4 million as of December 31, 2018, of which the Company expects to recognize approximately 73.2% of the revenue over the next 12 months and the remainder thereafter. Payment terms and conditions vary by contract type, although terms generally include a requirement of payment within 30 to 90 days. In instances where the timing of revenue recognition differs from the timing of invoicing, the Company has determined its contracts generally do not include a significant financing component. The primary purpose of the Company’s invoicing terms is to provide customers with simplified and predictable ways of purchasing its products and services, not to receive financing from our customers or to provide customers with financing. Examples include invoicing at the beginning of a subscription term with maintenance and support revenue recognized ratably over the contract period, and multi-year on-premises licenses that are invoiced annually with product revenue recognized upon delivery. Significant Judgments The Company’s contracts with customers often include promises to transfer multiple products and services to a customer. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. Judgment is required to determine the standalone selling price (“SSP”) for each distinct performance obligation. For products and services aside from maintenance and support, the Company estimates SSP by adjusting the list price by historical discount percentages. SSP for software and hardware maintenance and support fees is based on the stated percentages of the fees charged for the respective products. The Company’s perpetual and term software licenses have significant standalone functionality and therefore revenue allocated to these performance obligations are recognized at a point in time upon electronic delivery of the download link and the license keys. Product maintenance and support services are satisfied over time as they are stand-ready obligations throughout the support period. As a result, revenues associated with maintenance services are deferred and recognized as revenue ratably over the term of the contract. Revenues associated with professional services are recognized at a point in time upon customer acceptance. Assets Recognized from Costs to Obtain a Contract with a Customer The Company recognizes an asset for the incremental costs of obtaining a contract with a customer if it expects the benefit of those costs to be longer than one year. The Company has determined that its sales commission program meets the requirements for cost capitalization. Total capitalized costs to obtain a contract were immaterial during the periods presented and are included in other current and long-term assets on our consolidated balance sheets. The Company applies a practical expedient to expense costs as incurred for costs to obtain a contract with a customer when the amortization period would have been one year or less. (h) Property and Equipment Property and equipment are recorded at cost. Depreciation is recognized using the straight-line method over the estimated useful lives of the assets (3 to 7 years). Leasehold improvements are amortized on a straight-line basis over the terms of the respective leases or over their estimated useful lives, whichever is shorter. (i) Goodwill and Other Intangible Assets Goodwill represents the excess of the purchase price over the estimated fair value of net tangible and identifiable intangible assets acquired in business combinations. The Company has not amortized goodwill related to its acquisitions, but instead tests the balance for impairment. The Company evaluates goodwill for impairment annually or more frequently when an event occurs or circumstances change that indicate that the carrying value may not be recoverable. The Company tests goodwill for impairment by first comparing the book value of net assets to the fair value of the reporting unit. If the fair value is determined to be less than the book value or qualitative factors indicate that it is more likely than not that goodwill is impaired, a second step is performed to compute the amount of impairment as the difference between the estimated fair value of goodwill and the carrying value. The Company’s annual impairment assessment is performed at December 31st of each year, and the Company has determined there to be no impairment for any of the periods presented. The Company has adopted the provisions of ASU 2017-4, “Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. " The new accounting pronouncement eliminates the second step of the goodwill impairment test. As a result, the Company's goodwill impairment test as of December 31, 2018 and December 31, 2017 included only one step, which is a comparison of the carrying value of its one reporting unit to its fair value, and any excess carrying value, up to the amount of goodwill allocated to that reporting unit, is impaired. This new accounting pronouncement also eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. The fair value of the Company's single reporting unit for purposes of its goodwill impairment test exceeded its carrying value as of December 31, 2018 and thus the Company determined there was no impairment of goodwill. As of December 31, 2017, the Company's single reporting unit for purposes of its goodwill impairment test had a negative carrying value and thus the Company determined there was no impairment of goodwill. Identifiable intangible assets include (i) assets acquired through business combinations, which include customer contracts and intellectual property, and (ii) patents amortized over three years using the straight-line method. The gross carrying amount and accumulated amortization of goodwill and other intangible assets as of December 31, 2018 and 2017 are as follows: December 31, 2018 December 31, 2017 Goodwill $ 4,150,339 $ 4,150,339 Other intangible assets: Gross carrying amount $ 3,891,241 $ 3,816,402 Accumulated amortization (3,799,907 ) (3,674,771 ) Net carrying amount $ 91,334 $ 141,631 For the years ended December 31, 2018 and 2017 , amortization expense was $125,136 and $158,789 , respectively. As of December 31, 2018 , amortization expense for existing identifiable intangible assets is expected to be $42,814 , $38,485 and $10,035 for the years ended December 31, 2019 , 2020 and 2021 , respectively. Such assets will be fully amortized at December 31, 2021 . (j) Software Development Costs and Purchased Software Technology In accordance with the authoritative guidance issued by the FASB on costs of software to be sold, leased, or marketed, costs associated with the development of new software products and enhancements to existing software products are expensed as incurred until technological feasibility of the product has been established. Based on the Company’s product development process, technological feasibility is established upon completion of a working model. Amortization of software development costs is recorded at the greater of the straight-line basis over the product’s estimated life, or the ratio of current period revenue of the related products to total current and anticipated future revenue of these products. The gross carrying amount and accumulated amortization of software development costs as of December 31, 2018 and 2017 are as follows: December 31, 2018 December 31, 2017 Software development costs: Gross carrying amount $ 2,950,132 $ 2,917,215 Accumulated amortization (2,861,363 ) (2,637,801 ) Software development costs, net $ 88,769 $ 279,414 During the years ended December 31, 2018 and 2017 , the Company recorded $223,564 and $268,144 , respectively, of amortization expense related to capitalized software costs. As of December 31, 2018 , amortization expense for software development costs is expected to be $55,174 and $1,146 for the years ended December 31, 2019 and 2020 , respectively. Such assets will be fully amortized at December 31, 2020 . (k) Income Taxes The Company records income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for future tax consequences attributable to 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 realized or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. In determining the period in which related tax benefits are realized for financial reporting purposes, excess share-based compensation deductions included in net operating losses are realized after regular net operating losses are exhausted. The Company accounts for uncertain tax positions in accordance with the authoritative guidance issued by the FASB on income taxes, which addresses the determination of whether tax benefits claimed or expected to be claimed on a tax return, should be recorded in the financial statements. Pursuant to the authoritative guidance, the Company may recognize the tax benefit from an uncertain tax position only if it meets the “more likely than not” threshold that the position will be sustained on examination by the taxing authority, based on the technical merits of the position or expiration of statutes. The tax benefits recognized in the financial statements from such a position should be measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. In addition, the authoritative guidance addresses de-recognition, classification, interest and penalties on income taxes, accounting in interim periods, and also requires increased disclosures. The Company includes interest and penalties related to its uncertain tax positions as part of income tax expense within its consolidated statement of operations. See Note ( 5 ) Income Taxes for additional information. (l) Long-Lived Assets The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. If the sum of the expected future cash flows, undiscounted and without interest, is less than the carrying amount of the asset, an impairment loss is recognized as the amount by which the carrying amount of the asset exceeds its fair value. (m) Share-Based Payments The Company accounts for share-based payments in accordance with the authoritative guidance issued by the FASB on share-based compensation, which establishes the accounting for transactions in which an entity exchanges its equity instruments for goods or services. Under the provisions of the authoritative guidance, share-based compensation expense is measured at the grant date, based on the fair value of the award, and is recognized as an expense over the requisite employee service period (generally the vesting period), net of actual forfeitures. For share-based payment awards that contain performance criteria share-based compensation, expense is recorded when the achievement of the performance condition is considered probable of achievement and is recorded on a straight-line basis over the requisite service period. If such performance criteria are not met, no compensation cost is recognized and any recognized compensation cost is reversed. The Company estimates the fair value of share-based payments using the Black-Scholes option-pricing model or the Monte Carlo simulation model if a market condition exists. Share-based compensation expense for a share-based payment award with a market condition is recorded on a straight-line basis over the longer of the explicit service period or the service period derived from the Monte Carlo simulation. Additionally, share-based awards to non-employees are expensed over the period in which the related services are rendered at their fair value. All share-based awards are expected to be fulfilled with new shares of common stock. (n) Foreign Currency Assets and liabilities of foreign operations are translated at rates of exchange at the end of the period, while results of operations are translated at average exchange rates in effect for the period. Gains and losses from the translation of foreign assets and liabilities from the functional currency of the Company’s subsidiaries into the U.S. dollar are classified as accumulated other comprehensive loss in stockholders’ deficit. Gains and losses from foreign currency transactions are included in the consolidated statements of operations within interest and other loss, net. During the years ended December 31, 2018 and 2017 , foreign currency transactional gains (loss) totaled approximately $(207,242) and $72,167 , respectively. (o) Earnings Per Share (EPS) Basic EPS is computed based on the weighted average number of shares of common stock outstanding. Diluted EPS is computed based on the weighted average number of common shares outstanding increased by dilutive common stock equivalents, attributable to stock option awards, restricted stock awards and Series A redeemable convertible preferred stock outstanding. The following represents the common stock equivalents that were excluded from the computation of diluted shares outstanding because their effect would have been anti-dilutive for the years ended December 31, 2018 and 2017 : Year Ended December 31, 2018 2017 Stock options, warrants and restricted stock 2,997,330 16,434,296 Series A redeemable convertible preferred stock 8,781,516 8,781,516 Total anti-dilutive common stock equivalents 11,778,846 25,215,812 The following represents a reconciliation of the numerators and denominators of the basic and diluted EPS computation: Year Ended December 31, 2018 2017 Numerator: Net income (loss) $ (906,714 ) $ 1,052,401 Effects of Series A redeemable convertible preferred stock: Less: Accrual of Series A redeemable convertible preferred stock dividends 1,035,977 873,043 Less: Accretion to redemption value of Series A redeemable convertible preferred stock 254,212 — Less: Deemed dividend on Series A redeemable convertible preferred stock $ 2,269,042 $ — Net income (loss) attributable to common stockholders $ (4,465,945 ) $ 179,358 Denominator: Weighted average basic shares outstanding 93,330,146 44,413,061 Effect of dilutive securities: Stock options, warrants and restricted stock — 2,586,266 Series A redeemable convertible preferred stock — — Weighted average diluted shares outstanding 93,330,146 46,999,327 EPS: Basic net income (loss) per share attributable to common stockholders $ (0.05 ) $ — Diluted net income (loss) per share attributable to common stockholders $ (0.05 ) $ — (p) Investments As of December 31, 2018 and 2017 , the Company did not have any cost-method investments. (q) Treasury Stock The Company accounts for treasury stock under the cost method and includes treasury stock as a component of stockholders’ deficit. (s) Recently Adopted Accounting Pronouncements Revenue from Contracts with Customers In May 2014, the FASB ("Financial Accounting Standards Board") issued new guidance which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. This new guidance replaces most existing revenue recognition guidance in GAAP in the United States and requires entities to recognize revenue when control of the promised goods or services is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. In addition, the standard requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. We adopted the new guidance as of January 1, 2018 using the modified retrospective transition method applied to those contracts which were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under previous revenue guidance. The most significant impact of the standard relates to our accounting for our term license revenue. Specifically, for Freestor software subscription licenses, revenue is now recognized at the time of delivery rather than ratably over the subscription period. The adoption of the standard resulted in an increase to the opening balance of accumulated deficit of $8.9 million , related to the cumulative effect of a decrease in deferred revenue of $5.4 million , an increase in contract assets of $3.1 million from the upfront recognition of term licenses and the general requirement to allocate the transaction price on a relative stand-alone selling price, and an increase of $0.4 million in prepaid expenses and other current assets. Following is a summary of the impact to the Company’s current financial results from adopting the new revenue recognition standard: Statements of Operations Under Previous Guidance New Revenue Standard Adjustment Under Current Accounting Guidance Year Ended December 31, 2018 Product revenue 9,250,082 (3,483,550 ) 5,766,532 Support and services revenue 12,071,374 — 12,071,374 Selling and marketing 4,461,572 (7,875 ) 4,453,697 Income tax expense (benefit) 233,288 — 233,288 Net income (loss) 2,568,961 (3,475,675 ) (906,714 ) Net loss attributable to common stockholders (990,270 ) (3,475,675 ) (4,465,945 ) Basic net loss per share attributable to common stockholders (0.01 ) (0.04 ) (0.05 ) Diluted net loss per share attributable to common stockholders (0.01 ) (0.04 ) (0.05 ) Balance Sheets Under Previous Guidance New Revenue Standard Adjustment Under Current Accounting Guidance December 31, 2018 Prepaid expenses and other current assets 1,488,171 421,675 1,909,846 Contract assets, net, current — 637,179 637,179 Contract assets, net, long-term — 516,643 516,643 Deferred revenue, net, current 8,735,622 (1,876,030 ) 6,859,592 Deferred tax liabilities, net 297,890 — 297,890 Deferred revenue, net, long-term 4,510,331 (2,003,433 ) 2,506,898 Accumulated deficit (128,362,754 ) 5,454,960 (122,907,794 ) The adoption of the revenue recognition standard had no impact to cash from or used in operating, financing, or investing on our condensed consolidated statements of cash flows. (t) Recently Issued Accounting Pronouncements In August 2018, the FASB issued ASU 2018-14, Compensation—Retirement Benefits—Defined Benefit Plans—General: Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans . The objective of the guidance is to improve the effectiveness of disclosure requirements on defined benefit pension plans and other postretirement plans. The guidance is effective for fiscal years beginning after December 15, 2020. The Company does not expect adoption of the new standard will have a material impact on its Condensed Consolidated Financial Statements.. In July 2018, the FASB issued ASU 2018-10 Leases (Topic 842),Codification Improvements and ASU 2018-11 Leases (Topic 842), Targeted Improvements , to provide additional guidance for the adoption of Topic 842 . ASU 2018-10 clarifies certain provisions and correct unintended app

Fair Value Measurements

Fair Value Measurements	12 Months Ended
	Dec. 31, 2018
Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company measures its cash equivalents, marketable securities and derivative instruments at fair value. Fair value is an exit price, representing the amount that would be received on the sale of an asset or that would be paid to transfer a liability in an orderly transaction between market participants. As a basis for considering such assumptions, the Company utilizes a three-tier fair value hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value. Fair Value Hierarchy The methodology for measuring fair value specifies a hierarchy of valuation techniques based upon whether the inputs to those valuation techniques reflect assumptions other market participants would use based upon market data obtained from independent sources (observable inputs) or reflect the Company’s own assumptions of market participant valuation (unobservable inputs). As a result, observable and unobservable inputs have created the following fair value hierarchy: • Level 1 – Quoted prices in active markets that are unadjusted and accessible at the measurement date for identical, unrestricted assets or liabilities. At December 31, 2018 and 2017 , the Level 1 category included money market funds and commercial paper, which are included within “cash and cash equivalents” in the consolidated balance sheets. • Level 2 – Quoted prices for identical assets and liabilities in markets that are not active, quoted prices for similar assets and liabilities in active markets or financial instruments for which significant inputs are observable, either directly or indirectly. The Company had no Level 2 securities at December 31, 2018 and 2017 . • Level 3 – Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable. At December 31, 2018 and 2017 , the Level 3 category included derivatives, which are included in "other long-term liabilities" in the consolidated balance sheets with the change in fair value from the period included in "interest and other loss, net" in the consolidated statement of operations. The Company did not hold any cash, cash equivalents or marketable securities categorized as Level 3 as of December 31, 2018 or 2017 . Measurement of Fair Value The Company measures fair value as an exit price using the procedures described below for all assets and liabilities measured at fair value. When available, the Company uses unadjusted quoted market prices to measure fair value and classifies such items within Level 1. If quoted market prices are not available, fair value is based upon financial models that use, when possible, current market-based or independently-sourced market parameters such as interest rates and currency rates. Items valued using financial generated models are classified according to the lowest level input or value driver that is significant to the valuation. Thus, an item may be classified in Level 3 even though there may be inputs that are readily observable. If quoted market prices are not available, the valuation model used generally depends on the specific asset or liability being valued. The determination of fair value considers various factors including interest rate yield curves and time value underlying the financial instruments. The fair value of the Company’s investments in corporate debt and government securities have been determined utilizing third party pricing services and reviewed by management. The pricing services use inputs to determine fair value which are derived from observable market sources including reportable trades, benchmark curves, credit spreads, broker/dealer quotes, bids, offers, and other industry and economic events. These investments are included in Level 2 of the fair value hierarchy. The fair value of the Company’s derivatives were valued using the Black-Scholes pricing model adjusted for probability assumptions, with all significant inputs, except for the probability and volatility assumptions, derived from or corroborated by observable market data such as stock price and interest rates. The probability and volatility assumptions are both significant to the fair value measurement and unobservable. These embedded derivatives are included in Level 3 of the fair value hierarchy. The fair value of the Company’s short-term loan was based upon current rates offered for similar financial instruments to the Company. Items Measured at Fair Value on a Recurring Basis The following table presents the Company’s assets and liabilities that are measured at fair value on a recurring basis at December 31, 2018 : Fair Value Measurements at Reporting Date Using Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant other Inputs (Level 2) Significant Unobservable Inputs (Level 3) Cash equivalents: Money market funds $ — $ — $ — $ — Total cash equivalents — — — — Derivative liabilities: Derivative Instruments 498,086 — — 498,086 Total derivative liabilities 498,086 — — 498,086 Total assets and liabilities measured at fair value $ 498,086 $ — $ — $ 498,086 The following table presents the Company’s assets and liabilities that are measured at fair value on a recurring basis at December 31, 2017 : Fair Value Measurements at Reporting Date Using Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant other Inputs (Level 2) Significant Unobservable Inputs (Level 3) Cash equivalents: Money market funds and commercial paper $ — $ — $ — $ — Total cash equivalents — — — — Derivative liabilities: Derivative Instruments 445,838 — — 445,838 Total derivative liabilities 445,838 — — 445,838 Total assets and liabilities measured at fair value $ 445,838 $ — $ — $ 445,838 The fair value of the Company’s derivatives were valued using the Black-Scholes pricing model adjusted for probability assumptions, with all significant inputs, except for the probability and volatility assumptions, derived from or corroborated by observable market data such as stock price and interest rates. The probability and volatility assumptions are both significant to the fair value measurement and unobservable. These embedded derivatives are included in Level 3 of the fair value hierarchy. The following table presents the Company’s assets measured at fair value on a recurring basis using significant unobservable inputs (Level 3) as of each of the years ended December 31, 2018 and 2017 : Fair Value Measurements Using Significant Unobservable Inputs (Level 3) December 31, 2018 December 31, 2017 Beginning Balance $ 445,838 $ 336,862 Total loss recognized in earnings 52,248 108,976 Ending Balance $ 498,086 $ 445,838

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Information pertaining to the Company’s income (loss) before income taxes and the applicable provision for income taxes is as follows: December 31, 2018 2017 Income (loss) before income taxes: Domestic income (loss) $ (1,105,447 ) $ 590,660 Foreign income 432,021 469,347 Total income (loss) before income taxes: (673,426 ) 1,060,007 Provision (benefit) for income taxes: Current: Federal $ (231,564 ) $ 2,640 State and local (47,304 ) (85,972 ) Foreign 244,396 238,729 (34,472 ) 155,397 Deferred: Federal $ 208,709 $ (530,478 ) State and local 308 (8,215 ) Foreign 58,743 390,902 267,760 (147,791 ) Total provision for income taxes: $ 233,288 $ 7,606 During 2018 and 2017 , the Company recorded a tax provision of $233,288 and $7,606 , respectively, related to federal, state and local and foreign income taxes. The tax provisions include a tax benefit related to our Minimum Tax Credit carryforwards which are now realizable on a more-likely-than-not basis as such amounts will be refundable under the TCJA, partially offset with the accrual of foreign withholding taxes as the Company is no longer permanently reinvesting its foreign earnings. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and for income tax purposes. Significant components of the Company’s deferred tax assets and liabilities are as follows: December 31, 2018 2017 Deferred Tax Assets: Allowance for receivables $ 35,218 $ 76,266 Deferred revenue 852,015 1,970,216 Share-based compensation 21,940 517,841 Accrued expenses and other liabilities 341,553 404,316 Domestic net operating loss carryforwards 19,405,651 19,572,148 Foreign net operating loss carryforwards 198,017 17,997 Tax credit carryforwards 3,106,022 3,106,022 AMT tax credit carryforwards 233,007 464,571 Capital loss carryforwards 31,466 57,768 Fixed assets 178,502 218,412 Interest expense carryforwards 63,823 — Intangibles 287,547 625,126 Sub-total 24,754,761 27,030,683 Valuation allowance (22,424,261 ) (25,602,357 ) Total Deferred Tax Assets 2,330,500 1,428,326 Deferred Tax Liabilities: Prepaid commissions and other (100,569 ) — Tax method changes (1,227,047 ) — Deferred state income tax (279,540 ) (450,797 ) Foreign withholding taxes (481,892 ) (472,112 ) Total Deferred Tax Liabilities (2,089,048 ) (922,909 ) Net Deferred Tax Assets $ 241,452 $ 505,417 As of each reporting date, the Company considers new evidence, both positive and negative, that could affect its view of the future realization of deferred tax assets. In assessing the Company’s ability to recover its deferred tax assets, the Company evaluated whether it is more likely than not that some portion or the entire deferred tax asset will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income in those periods in which temporary differences become deductible and/or net operating losses can be utilized. The Company considered all positive and negative evidence when determining the amount of the net deferred tax assets that are more likely than not to be realized. This evidence includes, but is not limited to, historical earnings, scheduled reversal of taxable temporary differences, tax planning strategies and projected future taxable income. Based on these factors the Company determined that its U.S. deferred tax assets with the exception of its Minimum Tax Credit are not realizable on a more-likely-than-not basis and has recorded a full valuation allowance against such net deferred tax assets. The Company’s valuation allowance decreased by $1.2 million due to operations and an additional $2.0 million primarily related to the adoption of ASC 606. As of December 31, 2018 , the Company had federal net operating loss carry forwards of approximately $86.1 million which are set to expire beginning in 2030, if not utilized . As of December 31, 2018 , the Company had approximately $3.1 million of research and development tax credit carryforwards which expire at various dates beginning in 2023, if not utilized. For U.S. purposes, the Company has not completed its evaluation of net operating losses and credit carryforwards utilization limitations under Internal Revenue Code, as amended (the “Code”), Section 382/383, change of ownership rules. If the Company has had a change in ownership, the net operating losses and credit carryforwards would be limited as to the amount that could be utilized each year and could be eliminated, based on the Code. The effective tax rate before income taxes varies from the current statutory federal income tax rate as follows: December 31, 2018 2017 Tax at Federal statutory rate $ (141,419 ) $ 371,003 Increase (reduction) in income taxes resulting from: State and local taxes 543,278 355,888 Non-deductible expenses 200,464 (50,579 ) Stock compensation 509,951 1,273,956 Net effect of foreign operations 79,607 (14,022 ) Uncertain tax positions (60,994 ) (41,482 ) Impact of U.S tax reform — 14,295,386 Change in valuation allowance (1,241,052 ) (15,072,298 ) Foreign withholding taxes 143,120 468,376 Decrease in unrecognized tax benefits — (1,427,906 ) Other 200,333 (150,716 ) $ 233,288 $ 7,606 On December 22, 2017 the U.S. government enacted comprehensive tax reform commonly referred to as the Tax Cuts and Jobs Act (“TCJA”). Under ASC 740, the effects of changes in tax rates and laws are recognized in the period which the new legislation is enacted. Among other things, the TCJA (1) reduces the US statutory corporate income tax rate from 35% to 21% effective January 1, 2018 (2) eliminates the corporate alternative minimum tax (3) requires companies to record/pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred (4) creates new taxes on certain foreign sourced earnings (5) changes rules related to uses and limitations of net operating loss carryforwards beginning after December 31, 2017. While the TCJA provides for a modified territorial tax system, beginning in 2018, global intangible low-taxed income (“GILTI”) provisions will be applied providing an incremental tax on low taxed foreign income. The GILTI provisions require inclusions in U.S. taxable income related to foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary’s tangible assets. Under U.S. GAAP, the Company is allowed to make an accounting policy choice of either (1) treating taxes due on future U.S. inclusions in taxable income elated to GILTI as a current-period expense when incurred (the “period cost method”) or (2) factoring such amounts into the Company’s measurement of its deferred taxes (the “deferred method”). The Company has selected the “period cost method” as its accounting policy with respect to the new GILTI tax rules. The TCJA reduces the corporate tax rate to 21% effective January 1, 2018. The Company remeasured its U.S. deferred tax assets and liabilities based on the lower federal rate and recorded a provisional income tax benefit of $13.5 million , offset by change in its valuation allowance of $13.6 million . The TCJA also enacted a one-time transition tax, which is based on the Company’s total post-1986 earnings and profits (“E&P”) that were previously deferred from U.S. income taxes. The Company recorded a provisional amount for the one-time transition tax liability for all of its foreign subsidiaries resulting in an income tax expense of $0.7 million , offset by valuation allowance. The Company has not yet completed its calculation of the total post-1986 E&P for these foreign subsidiaries as certain information is not readily available. As of December 31, 2018, the Company has completed its 2017 income tax returns and its accounting for the enactment-date income tax effects of the TCJA with no material adjustments to the provisional amounts recorded at December 31, 2017. Due to the change in U.S. federal tax law, the Company does not intend to indefinitely reinvest any of its unremitted foreign earnings. As of December 31, 2018 , the Company has provided for additional foreign withholding taxes totaling approximately $0.5 million on approximately $3.4 million of undistributed earnings of its subsidiaries operating outside of the United States for which withholding tax applies. A reconciliation of the beginning and ending amount of unrecognized tax benefits, excluding interest and penalties, is as follows: 2018 2017 Balance at January 1, $ 180,202 $ 217,461 Increases to tax positions taken in prior years — 10,104 Expiration of statutes of limitation (42,275 ) (53,169 ) Translation (3,681 ) 5,806 Balance at December 31, $ 134,246 $ 180,202 At December 31, 2018 , $192,106 including interest, if recognized, would reduce the Company’s annual effective tax rate. As of December 31, 2018 , the Company had approximately $57,860 of accrued interest. The Company believes it is reasonably possible that $77,548 of its unrecognized tax benefits will reverse within the next 12 months due to expiring statute of limitations. The Company records any interest and penalties related to unrecognized tax benefits in income tax expense. The Company files federal, state, and foreign income tax returns in jurisdictions with varying statutes of limitations. The 2015 through 2018 tax years generally remain subject to examination by federal and most state tax authorities. In addition to the U.S., the Company’s major taxing jurisdictions include China, Taiwan, Japan, France and Germany.

Payables and Accruals [Abstract]
Notes Payable and Stock Warrants	Notes Payable and Stock Warrants As previously disclosed in the Company’s filings with the Securities and Exchange Commission, the Company was actively seeking financing in order to meet the Company’s operating cash flow needs. On November 17, 2017, HCP-FVA provided the Commitment, whereby it agreed to finance up to $3 million to the Company on the terms, and subject to the conditions, set forth in the Commitment letter. As part of the commitment, on November 17, 2017, the Company entered into a Loan Agreement with Lender and certain other loan parties named therein, pursuant to which the Lender made a Short Term Loan to the Company in the principal amount of $500,000 . Pursuant to the Short Term Loan, HCP-FVA received warrants to purchase 13,859,128 shares of the Company's common stock at a nominal exercise price ("Backstop Warrants"). The Short Term Loan was secured by all of the assets of the Company and guaranteed by each of the Company’s domestic subsidiaries. The Short Term Loan bore interest at a rate equal to the prime rate plus 0.75% . The Short Term Loan was due and payable on May 17, 2018, unless prepaid or satisfied through the issuance by the Company of Units (as defined below) in a proposed private placement (the "Financing") offered to certain eligible stockholders who were stockholders of the Company on November 17, 2017, as described below. On February 23, 2018, the Company closed on the Commitment from HCP-FVA to purchase up to $3 million of Units. HCP-FVA subscribed for the full $3 million of Units (at the Company’s election) in the Commitment by payment of $2.5 million in cash and the conversion of the $500,000 Short-Term Loan into Units. In consideration for HCP-FVA’s subscription of 3 million of Units, HCP-FVA was issued Financing Warrants (as hereinafter defined) to purchase 366,990,000 shares of the Company’s common stock for a nominal exercise price. In the Financing, the Company agreed to offer FalconStor stockholders as of November 17, 2017 who were accredited investors the opportunity to purchase up to a total of 40 million Units (inclusive of subscriptions by HCP-FVA). Each Unit had a purchase price of $0.371063 and consisted of the following (each, a “Unit”): i. $0.10 in senior secured debt (for a total of $4 million of senior secured debt assuming full subscription of the Financing), secured by all of the assets of the Company and guaranteed by each of the Company’s domestic subsidiaries, having an interest rate of prime plus 0.75% and a maturity date of June 30, 2021 (the “Term Loan”); ii. warrants to purchase 12.233 shares of the Company’s common stock for a nominal exercise price (for a total of 489.32 million shares assuming full subscription of the Financing) (the “Financing Warrants”); and iii. 0.0225 shares of Series A Preferred Stock at a per Unit price of $0.271063 (subject to increase to take into account accretion of the Series A Preferred Stock after December 31, 2018 ), all such shares to be acquired directly from their current holder, HCP-FVA. The closing of the Commitment effectively constituted HCP-FVA’s purchase of 30 million Units in the Financing. As a result, the maximum additional funds that the Company could receive in the Financing was $1,000,000 through the purchase of 10 million Units by other eligible stockholders. In exchange for serving as the backstop for the Financing, upon the closing of the Commitment, HCP-FVA received additional Backstop Warrants to purchase 41,577,382 shares of the Company’s common stock for a nominal exercise price, in addition to the 13,859,128 Backstop Warrants issued to HCP-FVA in connection with the making of the Short Term Loan. On February 23, 2018, in connection with HCP-FVA’s subscription in the Financing, the Company entered into an Amended and Restated Term Loan Credit Agreement, dated as of the same date (the “Amended and Restated Loan Agreement”), with HCP-FVA and certain other loan parties named therein setting forth the terms of the Term Loan. The Amended and Restated Loan Agreement amended and restated the Loan Agreement. Under the Amended and Restated Loan Agreement, in the event the Term Loan is prepaid for any reason, such prepayment will be subject to the payment of a premium in an amount equal to 5% of the principal amount prepaid. The Term Loan is required to be prepaid upon the occurrence of certain events, including but not limited to certain asset dispositions, the incurrence of additional indebtedness, the receipt of insurance proceeds, and a change of control, subject to certain exceptions. The Amended and Restated Loan Agreement has customary representations, warranties and affirmative and negative covenants. The negative covenants include financial covenants by the Company to maintain minimum cash denominated in U.S. dollars plus accounts receivable outstanding for less than 90 days of $2 million . The Amended and Restated Loan Agreement also contains customary events of default, including but not limited to payment defaults, cross defaults with certain other indebtedness, breaches of covenants, bankruptcy events and a change of control. In the case of an event of default, as administrative agent under the Loan Agreement, HCP-FVA may (and upon the written request of lenders holding in excess of 50% of the Term Loan, which must include HCP-FVA, is required to accelerate payment of all obligations under the Loan Agreement, and seek other available remedies). On April 23, 2018, HCP-FVA exercised most of its Backstop Warrants on a cash-less basis and was issued 53,370,601 shares of the Company's common stock. HCP-FVA continues to hold Backstop Warrants to purchase 1,543,630 shares of common stock. The Commitment and the Financing were approved by the Company’s Board of Directors, based on a recommendation of a special committee of independent directors, with Mr. Hale recusing himself. On October 9, 2018, FalconStor closed on the final tranche of its previously-announced Financing of Units to certain eligible stockholders of the Company. As a result, the Company received an additional $1,000,000 of gross proceeds from new investors (the “New Investors”) which is in addition to the $3,000,000 of gross proceeds previously received from HCP-FVA through the subscription of 30,000,000 Units pursuant to the Commitment on February 23, 2018. In addition to providing the Company with $1,000,000 of gross proceeds, the New Investors purchased $520,000 of the Term Loan held by HCP-FVA and 342,000 of the 900,000 shares of Series A Preferred Stock held by HCP-FVA. Financing Warrants to purchase 63,610,935 shares of Common Stock held by HCP-FVA were also cancelled. Accordingly, the New Investors hold Financing Warrants to purchase 185,942,009 shares of Common Stock and HCP-FVA now holds Financing Warrants to purchase 303,379,065 shares of Common Stock. The transfer of securities by HCP-FVA to New Investors was subject to certain transfer limitations to ensure the preservation of the Company’s net operating loss carry forward. In December 2018, the Company received proceeds of approximately $489,321 from the exercise of Financing Warrants. During the fiscal years-ended December 31, 2018 and December 31, 2017 , FalconStor was unable to make its Series A Preferred Stock quarterly dividend payments, and was subject to mandatory redemption under the Series A Preferred Stock purchase agreement. In conjunction with the Commitment, Hale Capital agreed to postpone the date of the mandatory redemption of the Series A Preferred Stock from August 5, 2017 to July 30, 2021, and to waive prior breaches of the terms of the Series A Preferred Stock which had also triggered a mandatory redemption right (“Series A Mandatory Redemption Extension”). Accordingly, as a result of these changes, for accounting purposes, the Series A Preferred Stock is considered new Series A Preferred Stock. As a result, the Company assessed whether the transaction was a troubled debt restructuring. Although the Company meets the criteria of a debtor experiencing financial difficulties as described above in Accounting Standards Code ("ASC") 470-60-55-8, Hale Capital was not granted a concession as defined in ASC 470-60-55-10 as the effective interest rate for both the Series A Preferred Stock and the Original Loan was higher following the restructuring of Series A Preferred Stock and Long-Term Debt compared to the interest rate immediately before the restructuring. Since no concession was granted, Troubled Debt Restructuring accounting guidance does not apply. As part of the analysis, the present value of the cash flows under the terms of the new Series A Preferred Stock and loans are greater than 10% different than the present value of the old Series A Preferred Stock and loans cash flows, as such extinguishment treatment applies. There is no beneficial conversion feature associated with the revised Series A Preferred Stock. When preferred stock is extinguished, the issuer should include the gain or loss on extinguishment in its net income attributable to common shareholders used to calculate earnings per share, as described in ASC 260-10-S99-2. When multiple instruments are issued in a single transaction, the total proceeds from the transaction should be allocated among the individual freestanding instruments identified. Since Hale Capital previously held all of the debt and Series A Preferred Stock, the restructuring is considered to be a capital transaction as of December 31, 2018 . As such the gain or loss was recorded in equity. ASC 470-20-25-2 requires that debt or stock with detachable warrants issued in a bundled transaction with debt and equity proceeds be accounted for separately, based on the relative fair values of each instrument. The proceeds allocated to the Backstop Warrants and Financing Warrants were valued at $4,143,000 . Derivative treatment did not apply to the warrants issued in association with the restructuring based upon the warrants being penny warrants (pre-paid stock). Warrants should be considered outstanding in earnings per share calculation if the Company is profitable to common shareholders; otherwise, warrants should be excluded as the effect would be antidilutive. At the time of the grant of Warrants in February 2017, the Company had insufficient shares outstanding to accommodate the exercise of the Financing Warrants granted as detailed in the Background section above. ASC 480 "Distinguishing Liabilities from Equity" is referenced below to determine whether such warrants need to be recorded as liabilities or equity. Warrant grants that do not have associated outstanding common shares should be recorded as liabilities as the Company would be required to settle such obligations using cash settlement (deficient by 368,533,620 shares). Changes in the fair value of the liability from period to period should be reflected within earnings. On June 22, 2018, the Company filed a certificate of amendment to the Company’s Restated Certificate of Incorporation to increase the authorized shares of common stock to 800,000,000 . As a result, the fair value of these Warrants have been reclassified to equity. The Warrants contain standard antidilution language; therefore, they do not prevent a freestanding instrument from being considered indexed to the issuer’s own stock. The initial transaction was recorded as follows: At Inception February 23, 2018 Basis Fair Value Series A redeemable convertible preferred stock, net $ 10,312,113 $ 8,709,684 Notes payable, net 2,728,778 2,457,249 Warrant liability — 4,143,000 Total $ 13,040,891 $ 15,309,933 Deemed dividend $ 2,269,042 The Series A Preferred Stock consists of the following: Series A redeemable convertible preferred stock principal balance $ 9,000,000 Accrued dividends 1,312,112 Discount (1,602,428 ) Total Series A redeemable convertible preferred stock, net at inception on February 23, 2018 8,709,684 Accrued dividends 683,742 Accretion of preferred stock 363,280 Total Series A redeemable convertible preferred stock, net at December 31, 2018 $ 9,756,706 The notes payable balance consists of the following: Notes payable principal balance $ 3,000,000 Deferred issuance costs (254,247 ) Discount (288,504 ) Total notes payable, net at inception on February 23, 2018 2,457,249 Proceeds from issuance of long-term debt 1,000,000 Revaluation of long-term debt (447,008 ) Accretion of discount 202,195 Deferred issuance costs (87,609 ) Total notes payable, net at December 31, 2018 $ 3,124,827

Equity [Abstract]
Series A Redeemable Convertible Preferred Stock	Series A Redeemable Convertible Preferred Stock The Company has 900,000 shares of Series A Preferred Stock outstanding . Pursuant to the Amended and Restated Certificate of Designations, Preferences and Rights for the Series A Preferred Stock (the ”Certificate of Designations”), each share of Series A Preferred Stock can be converted into shares of the Company’s Common Stock, at an initial conversion price equal to $1.02488 per share, subject to appropriate adjustments for any stock dividend, stock split, stock combination, reclassification or similar transaction, (i) at any time at the option of the holder or (ii) by the Company if, following the first anniversary of the issuance of the Series A Preferred Stock (subject to extension under certain circumstances), the volume weighted average trading price per share of the Company’s Common Stock for sixty ( 60 ) consecutive trading days exceeds 250% of the conversion price and continues to exceed 225% of the conversion price through the conversion date, subject at all times to the satisfaction of, and the limitations imposed by, the equity conditions set forth in the Certificate of Designations (including, without limitation, the volume limitations set forth therein). Pursuant to the Certificate of Designations, the holders of the Series A Preferred Stock are entitled to receive quarterly dividends at the prime rate (provided in the Wall Street Journal Eastern Edition) plus 5% (up to a maximum dividend rate of 10% ), payable in cash or in kind (i.e., through the issuance of additional shares of Series A Preferred Stock), except that the Company is not permitted to pay such dividends in cash while any indebtedness and the Company’s Amendment and Restated Loan Agreement remains outstanding without the consent of the holders of the Series A Preferred Stock. In addition, the declaration and payment of dividends is subject to compliance with applicable law and unpaid dividends will accrue. A holder’s right to convert its shares of Series A Preferred Stock and receive dividends in the form of Common Stock is subject to certain limitations including, among other things, that the shares of Common Stock issuable upon conversion or as dividends will not, prior to receipt of stockholder approval, result in any holder beneficially owning greater than 19.99% of the Company’s currently outstanding shares of Common Stock. The Series A Preferred dividends shall accrue whether or not the declaration or payment of such Series A Preferred dividends are prohibited by applicable law, whether or not the Company has earnings, whether or not there are funds legally available for the payment of such dividends and whether or not such dividends are authorized or declared. Upon certain triggering events, such as bankruptcy, insolvency or a material adverse effect or failure of the Company to issue shares of Common Stock upon conversion of the Series A Preferred Stock in accordance with its obligations, the holders may require the Company to redeem all or some of the Series A Preferred Stock at a price per share equal to the greater of (i) the sum of 100% of the stated value of a share of Series A Preferred Stock plus accrued and unpaid dividends with respect thereto, and (ii) the product of the number of shares of Common Stock underlying a share of Series A Preferred Stock and the closing price as of the occurrence of the triggering event. On or after July 30, 2021, each holder of Series A Preferred Stock can also require the Company to redeem its Series A Preferred Stock in cash at a per share price equal to 100% of the stated value of a share of Series A Preferred Stock plus accrued and unpaid dividends with respect thereto. Notwithstanding the forgoing, no holder of Series A Preferred Stock is permitted to exercise any rights or remedies upon a Breach Event or to exercise any redemption rights under the Certificate of Designations, unless approved by the holders of a majority of the then outstanding shares of Series A Preferred Stock. Upon consummation of a fundamental sale transaction, the Series A Preferred Stock shall be redeemed at a per share redemption price equal to the greater of (y) 250% of the per share purchase price of the Series A Preferred Stock and (z) the price payable in respect of such share of Series A Preferred Stock if such share of Series A Preferred Stock had been converted into such number of shares of Common Stock in accordance with the Certificate of Designations (but without giving effect to any limitations or restrictions contained therein) immediately prior to such fundamental sale transaction; provided however that the 250% threshold is changed to 100% if the fundamental sale transaction is approved by the two Series A Directors (as defined in the Certificate of Designations). In addition, if the Company consummates an equity or debt financing that results in more than $5.0 million of net proceeds to the Company and/or its subsidiaries, the holders of Series A Preferred Stock will have the right, but not the obligation, to require the Company to use the net proceeds in excess of $5.0 million to repurchase all or a portion of the Series A Preferred Stock at a per share price equal to the greater of (i) the sum of 100% of the stated value of such share of Series A Preferred Stock plus accrued and unpaid dividends with respect thereto, and (ii) the number of shares of Common Stock into which such share of Series A Preferred Stock is then convertible multiplied by the greater of (y) the closing price of the Common Stock on the date of announcement of such financing or (z) the closing price of the Common Stock on the date of consummation of such financing. Each holder of Series A Preferred Stock has a vote equal to the number of shares of Common Stock into which its Series A Preferred Stock would be convertible as of the record date. In addition, the holders of a majority of the Series A Preferred Stock must approve certain actions, including approving any amendments to the Company’s Charter or Bylaws that adversely affects the voting powers, preferences or other rights of the Series A Preferred Stock; payment of dividends or distributions; any liquidation, capitalization, reorganization or any other fundamental transaction of the Company; issuance of any equity security senior to or on parity with the Series A Preferred Stock as to dividend rights, redemption rights, liquidation preference and other rights; issuances of equity below the conversion price; any liens or borrowings other than non-convertible indebtedness from standard commercial lenders which does not exceed 80% of the Company’s accounts receivable; and the redemption or purchase of any of the capital stock of the Company. The Company has classified the Series A Preferred Stock as temporary equity in the financial statements as it is subject to redemption at the option of the holder under certain circumstances. As a result of the Company’s analysis of all the embedded conversion and put features within the Series A Preferred Stock, the contingent redemption put options in the Series A Preferred Stock were determined to not be clearly and closely related to the debt-type host and also did not meet any other scope exceptions for derivative accounting. Therefore, the contingent redemption put options are being accounted for as derivative instruments and the fair value of these derivative instruments was bifurcated from the Series A Preferred Stock and recorded as a liability. As of December 31, 2018 and December 31, 2017 the fair value of these derivative instruments was $498,086 and $445,838 , respectively, and were included in "other long-term liabilities" within the consolidated balance sheets. The loss on the change in fair value of these derivative instruments for the twelve months ended December 31, 2018 and December 31, 2017 of 52,248 and $108,976 , respectively, were included in “interest and other loss, net” within the consolidated statement of operations. The fair value of these derivative instruments and the loss recorded on the change in the fair value of these derivative instruments, which was included in “Interest and other income, net” within the condensed consolidated statement of operations, for the twelve months ended December 31, 2018 and 2017 , were as follows: Years Ended December 31, 2018 2017 Beginning Balance $ 445,838 $ 336,862 Total loss recognized in earnings 52,248 108,976 Ending Balance $ 498,086 $ 445,838 At the time of issuance, the Company recorded transaction costs, a beneficial conversion feature and the fair value allocated to the embedded derivatives as discounts to the Series A Preferred Stock. These costs were being accreted to the Series A Preferred Stock using the effective interest method through the stated redemption date of August 5, 2017, which represents the earliest redemption date of the instrument. This accretion was accelerated as of December 31, 2016 due to the failure of the financial covenants and the redemption right of the holders at that time. In connection with the Commitment, Hale agreed to the Series A mandatory extension and waived prior breaches of the terms of the Series A Preferred Stock. The Company included deductions for accretion, deemed and accrued dividends on the Series A Preferred Stock as adjustments to net income (loss) attributable to common stockholders on the statement of operations and in determining income (loss) per share for the twelve months ended December 31, 2018 and 2017 , respectively. The following represents a reconciliation of net loss attributable to common stockholders for the twelve months ended December 31, 2018 and 2017 , respectively: Years Ended December 31, 2018 2017 Net income (loss) $ (906,714 ) $ 1,052,401 Effects of Series A redeemable convertible preferred stock: Less: Accrual of Series A redeemable convertible preferred stock dividends 1,035,977 873,043 Less: Accretion to redemption value of Series A redeemable convertible preferred stock 254,212 — Less: Deemed dividend on Series A redeemable convertible preferred stock 2,269,042 — Net income (loss) attributable to common stockholders $ (4,465,945 ) $ 179,358

Share-Based Payment Arrangements	Share-Based Payment Arrangements On June 22, 2018, the Company's stockholders adopted the FalconStor Software, Inc. 2018 Incentive Stock Plan (the "2018 Plan"). The 2018 Plan is administered by the Compensation Committee and provides for the issuance of up to 147,199,698 shares of the Company's common stock upon the grant of shares with such restrictions as determined by the Compensation Committee to the employees and directors of, and consultants providing services to, the Company or its affiliates. Exercise prices of the options will be determined by the Compensation Committee, subject to the consent of Hale Capital. The vesting terms shall be performance based and determined by the Committee, subject to the consent of Hale Capital, based on various factors, including (i) the return of capital to the holders of the Series A Preferred Stock and the Company’s Common Stock in the event of a Change of Control, (ii) the repayment of the Company’s obligations under its senior secured debt, and (iii) the Company’s free cash flow. Seventy percent ( 70% ) of the Shares issuable under the 2018 Plan shall be granted as stock options. The remaining thirty percent ( 30% ) of the shares subject to the Plan plus any returned shares will be reserved for future grants of awards to new hires. The 2016 Incentive Stock Plan (the "2016 Plan") was terminated in April 2018. The following table summarizes the 2018 Plan, which was the only plan under which the Company was able to grant equity compensation as of December 31, 2018: Name of Plan Shares Shares Available Shares FalconStor Software, Inc. 2018 Incentive Stock Plan 147,199,698 147,199,698 — The following table summarizes the Company’s equity plans that have expired but that still have equity awards outstanding as of December 31, 2018 : Name of Plan Shares Available for Grant Shares Outstanding FalconStor Software, Inc., 2016 Incentive Stock Plan — 505,000 FalconStor Software, Inc., 2006 Incentive Stock Plan — 944,200 FalconStor Software, Inc., 2000 Stock Option Plan — 4,500 All outstanding options granted under the Company’s equity plans have terms of ten years .

Related to the 2016 Plan, many share-based compensation awards were forfeited and the related expense reversed accordingly, resulting in negative expense in the period. The following table summarizes the share-based compensation expense for all awards issued under the Company’s stock equity plans in the following line items in the consolidated statements of operations: Years ended December 31, 2018 2017 Cost of revenue - Support and Service 26,203 64,427 Research and development costs 77,116 233,955 Selling and marketing 19,615 48,286 General and administrative (58,262 ) 76,285 $ 64,672 $ 422,953 The Company did not recognize any tax benefits related to share-based compensation expense during the years ended December 31, 2018 and 2017 . The Company has the ability to issue both restricted stock and restricted stock units. The fair value of the restricted stock awards and restricted stock units are expensed at the fair value per share at date of grant for directors, officers and employees. A summary of the total stock-based compensation expense related to restricted stock awards and restricted stock units, which is included in the Company’s total share-based compensation expense for each respective year, is as follows: Years ended December 31, 2018 2017 Directors, officers and employees $ (49,289 ) $ 167,369 A summary of the Company’s restricted stock activity for 2018 is as follows: Number of Restricted Stock Awards Non-Vested at December 31, 2017 548,968 Granted — Vested (32,300 ) Forfeited (416,668 ) Non-Vested at December 31, 2018 100,000 Restricted stock and restricted stock units are fulfilled with new shares of common stock. The total intrinsic value of restricted stock for which the restrictions lapsed during the years ended December 31, 2018 and 2017 was $0 . Options granted to non-employee consultants have exercise prices equal to the fair market value of the stock on the date of grant and a contractual term of ten years . Restricted stock awards granted to non-employee consultants have a contractual term equal to the lapse of restriction(s) of each specific award. Vesting periods for share-based awards granted to non-employee consultants range from immediate vesting to three years depending on service requirements. A summary of the total stock-based compensation expense related to share-based awards granted to non-employee consultants, which is included in the Company’s total share-based compensation expense for each respective period, is as follows: Years ended December 31, 2018 2017 Non-qualified stock options $ — $ 41,159 Restricted stock awards — — $ — $ 41,159 The Company estimates the fair value of share-based payments using the Black-Scholes option-pricing model. For awards with market conditions the Company utilizes the Monte Carlo simulation model to estimate the fair value. The Company believes that these valuation techniques and the approach utilized to develop the underlying assumptions are appropriate in estimating the fair value of the Company’s share-based payments granted during the years ended December 31, 2018 and 2017 . Estimates of fair value are not intended to predict actual future events or the value ultimately realized by the employees who receive equity awards. No awards were granted during the year ended December 31, 2018. The per share weighted average fair value of share-based payments granted during the years ended December 31, 2017 was $0.23 . In addition to the exercise and grant date prices of the awards, certain weighted average assumptions were used to estimate the fair value of share-based payment grants in the respective periods are listed in the table below: Years ended December 31, 2018 2017 Expected dividend yield N/A 0% Expected volatility N/A 57 % - 59% Risk-free interest rate N/A 1.94% - 2.02% Expected term (years) N/A 5.5 Discount for post-vesting restrictions N/A N/A Options granted to officers, employees and directors during fiscal 2017 have exercise prices equal to the fair market value of the stock on the date of grant, a contractual term of ten years , and a vesting period generally of three years . The Company estimates expected volatility based primarily on historical daily volatility of the Company’s stock and other factors, if applicable. The risk-free interest rate is based on the United States treasury yield curve in effect at the time of grant. The expected option term is the number of years that the Company estimates that options will be outstanding prior to exercise. The expected term of the awards was determined based upon an estimate of the expected term of “plain vanilla” options as prescribed in SEC Staff Accounting Bulletin (“SAB”) No. 110. As of December 31, 2018 , there was approximately $0.0 million total unrecognized compensation cost related to the Company’s unvested stock options, restricted stock and restricted stock unit awards granted under the Company’s stock plans. The unrecognized compensation cost is expected to be recognized over a weighted-average period of 0.25 years. As of December 31, 2018 , the Company had 150,197,028 shares of common stock reserved for issuance upon the exercise or vesting of stock options, restricted stock, restricted stock units and warrants.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments The Company does not use derivative financial instruments for trading or speculative purposes. As of December 31, 2018 and 2017 , the Company had no foreign currency forward contracts outstanding. The Company did not utilize foreign currency forward contracts during the years ended December 31, 2018 and 2017 . As a result of the Company’s analysis of all the embedded conversion and put features within its Series A redeemable convertible preferred stock, the contingent redemption put options in the Series A redeemable convertible preferred stock were determined to not be clearly and closely related to the debt-type host and also did not meet any other scope exceptions for derivative accounting. Therefore the contingent redemption put options are being accounted for as derivative instruments and the fair value of these derivative instruments were bifurcated from the Series A redeemable convertible preferred stock and recorded as a liability. At the time of issuance of the Series A redeemable convertible preferred stock the fair value of these derivative instruments were recorded as a reduction to preferred stock. As of December 31, 2018 and 2017 , the fair value of these derivative instruments was $498,086 and $445,838 , respectively, and were included in "other long-term liabilities" within the consolidated balance sheets. The loss on the change in fair value of these derivative instruments for 2018 of $52,248 and the loss on the change in fair value of these derivative instruments for 2017 of $108,976 , were included in “interest and other loss, net” within the consolidated statement of operations.

Litigation

Commitments and Contingencies Disclosure [Abstract]
Litigation	Litigation In view of the inherent difficulty of predicting the outcome of litigation, particularly where the claimants seek very large or indeterminate damages, the Company generally cannot predict what the eventual outcome of the pending matters will be, what the timing of the ultimate resolution of these matters will be, or what the eventual loss, fines or penalties related to each pending matter may be. In accordance with the authoritative guidance issued by the FASB on contingencies, the Company accrues anticipated costs of settlement, damages and losses for claims to the extent specific losses are probable and estimable. The Company records a receivable for insurance recoveries when such amounts are probable and collectable. In such cases, there may be an exposure to loss in excess of any amounts accrued. If, at the time of evaluation, the loss contingency related to a litigation is not both probable and estimable, the matter will continue to be monitored for further developments that would make such loss contingency both probable and estimable and, the Company will expense these costs as incurred. If the estimate of a probable loss is a range and no amount within the range is more likely, the Company will accrue the minimum amount of the range. Other Claims The Company is subject to various legal proceedings and claims, asserted or unasserted, which arise in the ordinary course of business. While the outcome of any such matters cannot be predicted with certainty, such matters are not expected to have a material adverse effect on the Company’s financial condition or operating results. The Company continues to assess certain litigation and claims to determine the amounts, if any, that the Company believes may be paid as a result of such claims and litigation and, therefore, additional losses may be accrued and paid in the future, which could materially adversely impact the Company’s financial results, its cash flows and its cash reserves.

Hale, Jr., a member of the Company's Board of Directors, is a general partner of HCP-FVA, the holder in excess of 50% of the Company’s Series A redeemable convertible preferred stock. The Series A redeemable convertible preferred stock was purchased by Hale Capital Partners, LP, of which Mr. Hale is a general partner, pursuant to a September 16, 2013 stock purchase agreement with the Company at a time when Mr. Hale was not a director of the Company. Hale Capital Partners, LP subsequently assigned all of its rights in the Series A redeemable convertible preferred stock to HCP-FVA. Under the terms of the Certificate of Designations, the holders of the Series A convertible preferred stock are entitled, as a group, to nominate and to elect up to two directors so long as at least 85% of the Company's Series A redeemable convertible preferred stock is outstanding. HCP-FVA, the sole holder of the Series a convertible preferred stock, nominated and elected Mr. Hale in September 2013 and Michael P. Kelly on October 29, 2014, to the Company’s Board of Directors. On November 17, 2017, HCP-FVA provided a commitment letter to the Company agreeing to finance up to $3 million to the Company (the “Commitment”) on the terms, and subject to the conditions, set forth in that certain commitment letter. As part of that Commitment, on November 17, 2017, the Company entered into a Loan and Security Agreement with Lender and certain other loan parties named therein, pursuant to which the Lender made a short term loan to the Company in the principal amount of $500,000 payable on May 17, 2018. In connection with the Bridge Loan, the Company issued HCP-FVA Backstop Warrants to purchase 13,859,128 shares of Common Stock. See Note ( 7 ) Notes Payable and Stock Warrants for more information. On February 23, 2018, we closed on the Commitment whereby HCP-FVA purchased $3 million of Units (as defined in Note ( 7 ) Notes Payable and Stock Warrants ) to backstop a proposed private placement of Units to certain eligible stockholders of the Company. HCP-FVA subscribed for the full $3 million of Units (at the Company’s election) in the Commitment by payment of $2.5 million in cash and the conversion of the $500,000 Bridge Loan In connection therewith, the Company issued HCP-FVA additional BackStop Warrants to purchase 41,577,383 shares of Common Stock and Financing Warrants to purchase 366,990,000 shares of Common Stock. On October 9, 2018, FalconStor closed on the final tranche of its previously-announced Financing of Units to certain eligible stockholders of the Company. As a result, the Company received an additional $1,000,000 of gross proceeds from new investors (the “New Investors”) which is in addition to the $3,000,000 of gross proceeds previously received from HCP-FVA through the subscription of 30,000,000 Units pursuant to the Commitment on February 23, 2018. In addition to providing the Company with $1,000,000 of gross proceeds, the New Investors purchased $520,000 of the Term Loan held by HCP-FVA and 342,000 of the 900,000 shares of Series A Preferred Stock held by HCP-FVA. Financing Warrants to purchase 63,610,935 shares of Common Stock held by HCP-FVA were also cancelled.

The 2017 Plan was substantially completed by the end of the Company’s fiscal year ending December 31, 2017, and when combined with previous workforce reductions in the second quarter of Fiscal 2017 reduced the Company’s workforce to approximately 81 employees. On November 17, 2017, HCP-FVA, LLC (the “Lender”) provided a commitment letter to the Company agreeing to finance up to $3 million to the Company (the “Commitment”) on the terms, and subject to the conditions, set forth in that certain commitment letter (see Note (7) Short-Term Loan and Commitment ). As part of that Commitment, on November 17, 2017, the Company entered into a Loan and Security Agreement (the “Loan Agreement”) with Lender and certain other loan parties named therein, pursuant to which the Lender made a short term loan to the Company in the principal amount of $500,000 (the “Short Term Loan”). On February 23, 2018, the Company closed on the Commitment and the Lender subscribed for the full $3 million of Units in the Commitment by payment of $2.5 million in cash and the conversion of the $500,000 Short Term Loan. The $3 million term loan has an interest rate of prime plus 0.75% and a maturity date of June 30, 2021. The Lender is an affiliate of Hale Capital Partners, LP (together, "Hale Capital") and the Company's largest shareholder through its ownership of Series A redeemable preferred stock ("Series A Preferred Stock"), and an affiliate of Martin Hale, a Director of the Company. As part of the Commitment, Hale Captial also agreed to postpone the date of the optional redemption of the Series A Preferred Stock from August 5, 2017 to July 30, 2021, and to waive prior breaches of the terms of the Series A Preferred Stock which had triggered a redemption right. On October 9, 2018, FalconStor closed on the final tranche of its previously-announced Financing of Units (see Note (7) Short-Term Loan and Commitment ) to certain eligible stockholders of the Company. As a result, the Company received an additional $1,000,000 of gross proceeds from new investors (the “New Investors”) which is in addition to the $3,000,000 of gross proceeds previously received from HCP-FVA through the subscription of 30,000,000 Units pursuant to the Commitment on February 23, 2018. In December 2018, outstanding Warrants to purchase 489,321,074 were exercised resulting in the issuance of 489,321,074 shares of Common Stock (the “Warrant Exercise”). In connection with the Warrant Exercise, the Company received proceeds of approximately $489,321 , which was used to reduce the outstanding principal due on Amended and Restated Loan Agreement. We believe that our cash flows from operations and existing cash on hand are sufficient to conduct our planned operations and meet our contractual requirements through April 2, 2020.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	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 revenues and expenses during the reporting period. The Company’s significant estimates include those related to revenue recognition, accounts receivable allowances, share-based payment compensation, valuation of derivatives, capitalizable software development costs, valuation of goodwill and other intangible assets and income taxes. Actual results could differ from those estimates. The financial market volatility in many countries where the Company operates has impacted and may continue to impact the Company’s business. Such conditions could have a material impact on the Company’s significant accounting estimates discussed above.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. To increase the comparability of fair value measurements, a three-tier fair value hierarchy, which prioritizes the inputs used in the valuation methodologies, is as follows: Level 1 —Valuations based on quoted prices for identical assets and liabilities in active markets. Level 2 —Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3 —Valuations based on unobservable inputs reflecting our own assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment. As of December 31, 2018 and 2017 , the fair value of the Company’s financial instruments including cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximated carrying value due to the short maturity of these instruments.
Derivative Financial Instruments	Derivative Financial Instruments The Company does not use derivative instruments to hedge exposures to cash flow, market or foreign currency risk. Terms of convertible preferred stock are reviewed to determine whether or not they contain embedded derivative instruments that are required under Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 815 “Derivatives and Hedging” (“ASC 815”) to be accounted for separately from the host contract, and recorded on the balance sheet at fair value. The fair value of derivatives are required to be revalued at each reporting date, with corresponding changes in fair value recorded in current period operating results.
Revenue Recognition	The Company derives its revenue from sales of its products, support and services. Product revenue consists of the Company’s software integrated with industry standard hardware and sold as complete turn-key integrated solutions, as stand-alone software applications or sold on a subscription or consumption basis. Depending on the nature of the arrangement revenue, related to turn-key solutions and stand-alone software applications are generally recognized upon shipment and delivery of license keys. For certain arrangements revenue is recognized based on usage or ratably over the term of the arrangement. Support and services revenue consists of both maintenance revenues and professional services revenues. Revenue is recorded net of applicable sales taxes. In accordance with the authoritative guidance issued by the FASB on revenue recognition, the Company recognizes revenue when persuasive evidence of an arrangement exists, the fee is fixed or determinable, delivery has occurred, and collection of the resulting receivable is deemed probable. Products delivered to a customer on a trial basis are not recognized as revenue until the trial period has ended and acceptance has occurred by the customer. Reseller and distributor customers typically send the Company a purchase order when they have an end user identified. Nature of Products and Services Licenses for on-premises software provide the customer with a right to use the software as it exists when made available to the customer. Customers may purchase perpetual licenses or subscribe to licenses, which provide customers with the same functionality and differ mainly in the duration over which the customer benefits from the software. Revenue from distinct on-premises licenses is recognized upfront at the point in time when the software is made available to the customer. Revenue allocated to software maintenance and support services is recognized ratably over the contractual support period. Hardware products consist primarily of servers and associated components and function independently of the software products and as such as accounted for as separate performance obligations. Revenue allocated to hardware maintenance and support services is recognized ratably over the contractual support period. Professional services are primarily related to software implementation services and associated revenue is recognized upon customer acceptance. Contract Balances Timing of revenue recognition may differ from the timing of invoicing to customers. The Company records a contract asset or receivable when revenue is recognized prior to invoicing, or unearned revenue when revenue is recognized subsequent to invoicing. For perpetual licenses with multi-year product maintenance agreements, the Company generally invoices customers at the beginning of the coverage period. For multi-year subscription licenses, the Company generally invoices customers annually at the beginning of each annual coverage period. The Company records a contract asset related to revenue recognized for multi-year on-premises licenses as its right to payment is conditioned upon providing product support and services in future years. The opening balance of accounts receivable, net of allowance for doubtful accounts, was $4.2 million as of January 1, 2018. There was no adjustment needed to accounts receivable for the cumulative effect of applying ASC 606 under the modified retrospective method. The opening balance of short and long-term contract assets, net of allowance for doubtful accounts, and adjusted for the cumulative effect of applying ASC 606 under the modified retrospective method, was $3.1 million as of January 1, 2018. As of December 31, 2018 and 2017, accounts receivable, net of allowance for doubtful accounts, was $3.6 million and $4.2 million , respectively. As of December 31, 2018 and 2017, short and long-term contract assets, net of allowance for doubtful accounts, was $1.2 million and $0.0 million , respectively. The allowances for doubtful accounts reflect the Company’s best estimates of probable losses inherent in the accounts receivable and contract assets’ balances. The Company determines the allowances based on known troubled accounts, historical experience, and other currently available evidence. Write-offs in the accounts receivable and contract assets allowance accounts during the years ended December 31, 2018 and 2017 were $0.1 million and $0.1 million , respectively. Deferred revenue is comprised mainly of unearned revenue related maintenance and technical support on term and perpetual licenses. Maintenance and technical support revenue is recognized ratably over the coverage period. Deferred revenue also includes contracts for professional services to be performed in the future which are recognized as revenue when the company delivers the related service pursuant to the terms of the customer arrangement. Changes in deferred revenue were as follows: Twelve Months Ended December 31, 2018 Balance at December 31, 2017 18,360,690 Cumulative effect of applying ASC 606 under the modified retrospective method* (5,359,579 ) Deferral of revenue 14,249,597 Recognition of revenue (17,837,906 ) Change in reserves (46,312 ) Balance at December 31, 2018 $ 9,366,490 *See Note (1) Summary of Significant Accounting Policies, section (s) to our Consolidated Financial Statements for further information. Deferred revenue includes invoiced revenue allocated to remaining performance obligations that has not yet been recognized and will be recognized as revenue in future periods. Deferred revenue was $9.4 million as of December 31, 2018, of which the Company expects to recognize approximately 73.2% of the revenue over the next 12 months and the remainder thereafter. Payment terms and conditions vary by contract type, although terms generally include a requirement of payment within 30 to 90 days. In instances where the timing of revenue recognition differs from the timing of invoicing, the Company has determined its contracts generally do not include a significant financing component. The primary purpose of the Company’s invoicing terms is to provide customers with simplified and predictable ways of purchasing its products and services, not to receive financing from our customers or to provide customers with financing. Examples include invoicing at the beginning of a subscription term with maintenance and support revenue recognized ratably over the contract period, and multi-year on-premises licenses that are invoiced annually with product revenue recognized upon delivery. Significant Judgments The Company’s contracts with customers often include promises to transfer multiple products and services to a customer. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. Judgment is required to determine the standalone selling price (“SSP”) for each distinct performance obligation. For products and services aside from maintenance and support, the Company estimates SSP by adjusting the list price by historical discount percentages. SSP for software and hardware maintenance and support fees is based on the stated percentages of the fees charged for the respective products. The Company’s perpetual and term software licenses have significant standalone functionality and therefore revenue allocated to these performance obligations are recognized at a point in time upon electronic delivery of the download link and the license keys. Product maintenance and support services are satisfied over time as they are stand-ready obligations throughout the support period. As a result, revenues associated with maintenance services are deferred and recognized as revenue ratably over the term of the contract. Revenues associated with professional services are recognized at a point in time upon customer acceptance. Assets Recognized from Costs to Obtain a Contract with a Customer The Company recognizes an asset for the incremental costs of obtaining a contract with a customer if it expects the benefit of those costs to be longer than one year. The Company has determined that its sales commission program meets the requirements for cost capitalization. Total capitalized costs to obtain a contract were immaterial during the periods presented and are included in other current and long-term assets on our consolidated balance sheets. The Company applies a practical expedient to expense costs as incurred for costs to obtain a contract with a customer when the amortization period would have been one year or less.
Property and Equipment	Property and Equipment Property and equipment are recorded at cost. Depreciation is recognized using the straight-line method over the estimated useful lives of the assets (3 to 7 years). Leasehold improvements are amortized on a straight-line basis over the terms of the respective leases or over their estimated useful lives, whichever is shorter.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill represents the excess of the purchase price over the estimated fair value of net tangible and identifiable intangible assets acquired in business combinations. The Company has not amortized goodwill related to its acquisitions, but instead tests the balance for impairment. The Company evaluates goodwill for impairment annually or more frequently when an event occurs or circumstances change that indicate that the carrying value may not be recoverable. The Company tests goodwill for impairment by first comparing the book value of net assets to the fair value of the reporting unit. If the fair value is determined to be less than the book value or qualitative factors indicate that it is more likely than not that goodwill is impaired, a second step is performed to compute the amount of impairment as the difference between the estimated fair value of goodwill and the carrying value. The Company’s annual impairment assessment is performed at December 31st of each year, and the Company has determined there to be no impairment for any of the periods presented. The Company has adopted the provisions of ASU 2017-4, “Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. " The new accounting pronouncement eliminates the second step of the goodwill impairment test. As a result, the Company's goodwill impairment test as of December 31, 2018 and December 31, 2017 included only one step, which is a comparison of the carrying value of its one reporting unit to its fair value, and any excess carrying value, up to the amount of goodwill allocated to that reporting unit, is impaired. This new accounting pronouncement also eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. The fair value of the Company's single reporting unit for purposes of its goodwill impairment test exceeded its carrying value as of December 31, 2018 and thus the Company determined there was no impairment of goodwill. As of December 31, 2017, the Company's single reporting unit for purposes of its goodwill impairment test had a negative carrying value and thus the Company determined there was no impairment of goodwill. Identifiable intangible assets include (i) assets acquired through business combinations, which include customer contracts and intellectual property, and (ii) patents amortized over three years using the straight-line method.
Software Development Costs and Purchased Software Technology	Software Development Costs and Purchased Software Technology In accordance with the authoritative guidance issued by the FASB on costs of software to be sold, leased, or marketed, costs associated with the development of new software products and enhancements to existing software products are expensed as incurred until technological feasibility of the product has been established. Based on the Company’s product development process, technological feasibility is established upon completion of a working model. Amortization of software development costs is recorded at the greater of the straight-line basis over the product’s estimated life, or the ratio of current period revenue of the related products to total current and anticipated future revenue of these products.
Income Taxes	Income Taxes The Company records income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for future tax consequences attributable to 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 realized or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. In determining the period in which related tax benefits are realized for financial reporting purposes, excess share-based compensation deductions included in net operating losses are realized after regular net operating losses are exhausted. The Company accounts for uncertain tax positions in accordance with the authoritative guidance issued by the FASB on income taxes, which addresses the determination of whether tax benefits claimed or expected to be claimed on a tax return, should be recorded in the financial statements. Pursuant to the authoritative guidance, the Company may recognize the tax benefit from an uncertain tax position only if it meets the “more likely than not” threshold that the position will be sustained on examination by the taxing authority, based on the technical merits of the position or expiration of statutes. The tax benefits recognized in the financial statements from such a position should be measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. In addition, the authoritative guidance addresses de-recognition, classification, interest and penalties on income taxes, accounting in interim periods, and also requires increased disclosures. The Company includes interest and penalties related to its uncertain tax positions as part of income tax expense within its consolidated statement of operations.
Long-Lived Assets	Long-Lived Assets The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. If the sum of the expected future cash flows, undiscounted and without interest, is less than the carrying amount of the asset, an impairment loss is recognized as the amount by which the carrying amount of the asset exceeds its fair value.
Share-Based Payments	Share-Based Payments
Foreign Currency	Foreign Currency Assets and liabilities of foreign operations are translated at rates of exchange at the end of the period, while results of operations are translated at average exchange rates in effect for the period. Gains and losses from the translation of foreign assets and liabilities from the functional currency of the Company’s subsidiaries into the U.S. dollar are classified as accumulated other comprehensive loss in stockholders’ deficit. Gains and losses from foreign currency transactions are included in the consolidated statements of operations within interest and other loss, net.
Earnings Per Share (EPS)	Earnings Per Share (EPS) Basic EPS is computed based on the weighted average number of shares of common stock outstanding. Diluted EPS is computed based on the weighted average number of common shares outstanding increased by dilutive common stock equivalents, attributable to stock option awards, restricted stock awards and Series A redeemable convertible preferred stock outstanding.
Investments	Investments As of December 31, 2018 and 2017 , the Company did not have any cost-method investments.
Treasury Stock	Treasury Stock The Company accounts for treasury stock under the cost method and includes treasury stock as a component of stockholders’ deficit.
Recently Issued Accounting Pronouncements	Recently Adopted Accounting Pronouncements Revenue from Contracts with Customers In May 2014, the FASB ("Financial Accounting Standards Board") issued new guidance which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. This new guidance replaces most existing revenue recognition guidance in GAAP in the United States and requires entities to recognize revenue when control of the promised goods or services is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. In addition, the standard requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. We adopted the new guidance as of January 1, 2018 using the modified retrospective transition method applied to those contracts which were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under previous revenue guidance. The most significant impact of the standard relates to our accounting for our term license revenue. Specifically, for Freestor software subscription licenses, revenue is now recognized at the time of delivery rather than ratably over the subscription period. The adoption of the standard resulted in an increase to the opening balance of accumulated deficit of $8.9 million , related to the cumulative effect of a decrease in deferred revenue of $5.4 million , an increase in contract assets of $3.1 million from the upfront recognition of term licenses and the general requirement to allocate the transaction price on a relative stand-alone selling price, and an increase of $0.4 million in prepaid expenses and other current assets. Following is a summary of the impact to the Company’s current financial results from adopting the new revenue recognition standard: Statements of Operations Under Previous Guidance New Revenue Standard Adjustment Under Current Accounting Guidance Year Ended December 31, 2018 Product revenue 9,250,082 (3,483,550 ) 5,766,532 Support and services revenue 12,071,374 — 12,071,374 Selling and marketing 4,461,572 (7,875 ) 4,453,697 Income tax expense (benefit) 233,288 — 233,288 Net income (loss) 2,568,961 (3,475,675 ) (906,714 ) Net loss attributable to common stockholders (990,270 ) (3,475,675 ) (4,465,945 ) Basic net loss per share attributable to common stockholders (0.01 ) (0.04 ) (0.05 ) Diluted net loss per share attributable to common stockholders (0.01 ) (0.04 ) (0.05 ) Balance Sheets Under Previous Guidance New Revenue Standard Adjustment Under Current Accounting Guidance December 31, 2018 Prepaid expenses and other current assets 1,488,171 421,675 1,909,846 Contract assets, net, current — 637,179 637,179 Contract assets, net, long-term — 516,643 516,643 Deferred revenue, net, current 8,735,622 (1,876,030 ) 6,859,592 Deferred tax liabilities, net 297,890 — 297,890 Deferred revenue, net, long-term 4,510,331 (2,003,433 ) 2,506,898 Accumulated deficit (128,362,754 ) 5,454,960 (122,907,794 ) The adoption of the revenue recognition standard had no impact to cash from or used in operating, financing, or investing on our condensed consolidated statements of cash flows. (t) Recently Issued Accounting Pronouncements In August 2018, the FASB issued ASU 2018-14, Compensation—Retirement Benefits—Defined Benefit Plans—General: Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans . The objective of the guidance is to improve the effectiveness of disclosure requirements on defined benefit pension plans and other postretirement plans. The guidance is effective for fiscal years beginning after December 15, 2020. The Company does not expect adoption of the new standard will have a material impact on its Condensed Consolidated Financial Statements.. In July 2018, the FASB issued ASU 2018-10 Leases (Topic 842),Codification Improvements and ASU 2018-11 Leases (Topic 842), Targeted Improvements , to provide additional guidance for the adoption of Topic 842 . ASU 2018-10 clarifies certain provisions and correct unintended applications of the guidance such as the application of implicit rate, lessee reassessment of lease classification, and certain transition adjustments that should be recognized to earnings rather than to stockholders' equity. ASU 2018-11 provides an alternative transition method and practical expedient for separating contract components for the adoption of Topic 842 . In February 2016, the FASB issued ASU 2016-02 Leases (Topic 842) which requires an entity to recognize assets and liabilities arising from a lease for both financing and operating leases with terms greater than 12 months. ASU 2018-11, ASU 2018-10, and ASU 2016-02 (collectively, "the new lease standards") are effective for fiscal years beginning after December 15, 2018, with early adoption permitted. We plan to adopt the standard effective January 1, 2019, applying the package of practical expedients to leases that commenced before the effective date whereby we will elect to not reassess the following: (i) whether any expired or existing contracts contain leases; (ii) the lease classification for any expired or existing leases; and (iii) initial direct costs for any existing leases. We expect to record lease right of use assets of $2.9 million and related liabilities of $3.6 million on our balance sheet related to our operating leases. We have no financing leases. We expect no change to our consolidated statements of operations or cash flows. In July 2018, the FASB issued ASU 2018-09, Codification Improvements. The amendments in ASU 2018-09 affect a wide variety of Topics in the FASB Codification and apply to all reporting entities within the scope of the affected accounting guidance. The Company has evaluated ASU 2018-09 in its entirety and determined that the amendments related to Topic 718-740, Compensation-Stock Compensation-Income Taxes, are the only provisions that currently apply to the Company. The amendments in ASU 2018-09 related to Topic 718-740, Compensation-Stock Compensation-Income Taxes, clarify that an entity should recognize excess tax benefits related to stock compensation transactions in the period in which the amount of the deduction is determined. The amendments in ASU 2018-09 related to Topic 718-740 are effective for fiscal years beginning after December 15, 2018, with early adoption permitted. The Company does not expect the adoption of the new standard to have a material impact on the Company's Condensed Consolidated Financial Statements. In June 2018, the FASB issued ASU 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, to expand the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees and supersedes the guidance in Subtopic 505-50, Equity - Equity-Based Payments to Non-Employees . Under ASU 2018-07, equity-classified nonemployee share-based payment awards are measured at the grant date fair value on the grant date. The probability of satisfying performance conditions must be considered for equity-classified nonemployee share-based payment awards with such conditions. ASU 2018-07 is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. The Company does not expect the adoption of the new standard to have a material impact on the Company's Condensed Consolidated Financial Statements. In February 2018, the FASB issued ASU No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income , which provides entities the option to reclassify tax effects stranded in accumulated other comprehensive income as a result of the 2017 Tax Cuts and Jobs Act (the "TCJA”) to retained earnings. The guidance is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. The Company does not expect the adoption of this accounting standard to have a material impact on our financial position, results of operations, cash flows, or presentation thereof.
