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"), 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)	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.


	(c)	Reclassifications

	Certain prior year’s amounts have been reclassified to conform to the current year presentation.


	(d)	Use of Estimates

	The preparation of financial statements in conformity with generally accepted accounting principles 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, marketable securities, valuation of embedded derivatives, software development costs, goodwill and other intangible assets and income taxes. Actual results could differ from those estimates.

	The financial market volatility, both in the U.S. and in many other countries where the Company operates, has impacted and may continue to impact the Company’s business. Such conditions could have a material impact to the Company’s significant accounting estimates discussed above.


	(e)	Cash Equivalents, Restricted Cash and Marketable Securities

	The Company considers all highly liquid investments with maturities of three months or less when purchased to be cash equivalents. The Company records its cash equivalents and marketable securities at fair value in accordance with the authoritative guidance issued by the Financial Accounting Standards Board (“FASB”) on fair value measurements and disclosures. As of December 31, 2014 the Company’s cash equivalents consisted of money market funds. As of December 31, 2013, the Company’s cash equivalents consisted of money market funds and commercial paper. At December 31, 2014 and 2013, the fair value of the Company’s cash equivalents amounted to approximately $2.0 million and $8.5 million, respectively.

	As of December 31, 2013, the Company had $0.8 million of restricted cash. The restricted cash served as collateral related to deposit service indebtedness with the Company’s commercial bank. During 2014, this cash was released by the company's commercial bank and is no longer considered restricted cash.

	As of December 31, 2014 and 2013, the Company’s marketable securities consisted of corporate bonds and government securities. As of December 31, 2014 and 2013, the fair value of the Company’s marketable securities was approximately $10.9 million and $8.1 million, respectively. All of the Company’s marketable securities are classified as available-for-sale, and accordingly, unrealized gains and losses on marketable securities, net of tax, are reflected as a component of accumulated other comprehensive loss in stockholders’ equity. Any other-than-temporary impairments are recorded within interest and other (loss) income, net in the consolidated statement of operations. See Note (4) Marketable Securities for additional information.


	(f)	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, 2014 and 2013, 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.


	(g)	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 FASB 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.


	(h)	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 and as stand-alone software applications. 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 and 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 customers typically send the Company a purchase order when they have an end user identified. Distributor customers typically send the Company a purchase order when they have a reseller and an end user identified. For bundled arrangements that include either maintenance or both maintenance and professional services, the Company uses the residual method to determine the amount of product revenue to be recognized. Under the residual method, consideration is allocated to the undelivered elements based upon vendor-specific objective evidence (“VSOE”) of the fair value of those elements, with the residual of the arrangement fee allocated to and recognized as product revenue. If VSOE does not exist for all undelivered elements of an arrangement, the Company recognizes total revenue from the arrangement ratably over the term of the maintenance agreement. The Company's long-term portion of deferred revenue consists of (i) payments received for maintenance contracts with terms in excess of one year as of the balance sheet date, (ii) payments received for product sales bundled with multiple years of maintenance but for which VSOE did not exist for all undelivered elements of the arrangement, and (iii) payments received in connection with a joint development agreement entered into by the Company in 2013 pursuant to which certain revenue was deferred until final delivery and acceptance of the final software. The Company provides an allowance for product returns as a reduction of revenue, based upon historical experience and known or expected trends.

	Revenues associated with maintenance services are deferred and recognized as revenue ratably over the term of the contract. Revenues associated with software implementation and software engineering services are recognized when the services are performed. Costs of providing these services are included in cost of support and services.

	The Company has entered into various distribution, licensing and joint promotion agreements with OEMs, whereby the Company has provided to the OEM a non-exclusive software license to install the Company’s software on certain hardware or to resell the Company’s software in exchange for payments based on the products distributed by these OEMs. Such payments from the OEM or distributor are recognized as revenue in the period reported by the OEM.

	From time to time the Company will enter into funded software development arrangements. Under such arrangements, revenue recognition will not commence until final delivery and/or acceptance of the product. For arrangements where the Company has VSOE for the undelivered elements, the Company will follow the residual method and recognize product revenue upon final delivery and/or acceptance of the product. For arrangements where the Company does not have VSOE for the undelivered elements, the Company will recognize the entire arrangement fee ratably commencing at the time of final delivery and/or acceptance through the end of the service period in the arrangement. Certain arrangements, for which VSOE of fair value for the undelivered maintenance elements cannot be established, are accounted for as a single unit of accounting. The revenue recognized from single units of accounting are typically allocated and classified on the consolidated statements of operations as product revenue and support and services revenue. Since VSOE cannot be established, VSOE of similar maintenance offerings provides the basis for the support and services revenue classification, and the remaining residual consideration provides the basis for the product revenue classification. Final acceptance of the software delivered under the joint development agreement occurred on November 16, 2014. Therefore the Company will recognize the total committed fee as revenue ratably over a twenty-five and a half month period which began on November 16, 2014 and includes the contractual twenty-four month maintenance period. As of December 31, 2014, the Company recorded product revenue of approximately $0.6 million and maintenance revenue of approximately $0.2 million related to this agreement. As of December 2014, the Company recorded short term deferred revenue of $5.6 million and long term deferred revenue of $5.6 million, related to this agreement. If at any time, the customer elects to terminate their maintenance agreement, any unrecognized deferred revenue would be accelerated and recognized as revenue during the period in which the termination becomes effective.


(i)	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.


(j)	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 during the fourth quarter of each year, and the Company has determined there to be no impairment for any of the periods presented. Based on the Company’s analysis, the fair value of its reporting unit substantially exceeds the carrying value of its goodwill balances as of December 31, 2014 and 2013. 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 other intangible assets as of December 31, 2014 and 2013 are as follows:


		31-Dec-14				31-Dec-13
Goodwill		$	4,150,339			$	4,150,339

Other intangible assets:

Gross carrying amount		$	3,395,024			$	3,256,709

Accumulated amortization		(3,198,987		)		(3,077,113		)
Net carrying amount		$	196,037			$	179,596


For the years ended December 31, 2014, 2013 and 2012, amortization expense was $121,874, $122,951 and $118,789, respectively. As of December 31, 2014, amortization expense for existing identifiable intangible assets is expected to be $108,460, $64,965 and $22,612 for the years ended December 31, 2015, 2016 and 2017, respectively. Such assets will be fully amortized at December 31, 2017.


(k)	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, 2014 and 2013 are as follows:


		December 31, 2014				December 31, 2013
Software development costs:
Gross carrying amount		$	2,903,115			$	2,718,900

Accumulated amortization		(1,394,598		)		(922,825		)
Software development costs, net		$	1,508,517			$	1,796,075


During the years ended December 31, 2014, 2013 and 2012, the Company recorded $0.5 million, $0.3 million and $0.3 million, respectively, of amortization expense related to capitalized software costs. As of December 31, 2014, amortization expense for software development costs is expected to be $0.5 million, $0.4 million, $0.3 million, $0.2 million and $0.1 million for the years ended December 31, 2015, 2016, 2017, 2018 and 2019, respectively. Such assets will be fully amortized at December 31, 2019.


(l)	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 (6) Income Taxes for additional information.


(m)	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.


(n)	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 estimated 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 straight-line 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 straight-line over the longer of the explicit service period or the service period derived from the Monte Carlo simulation. The estimation of share-based awards that will ultimately vest requires judgment, and to the extent actual results or updated estimates differ from the Company’s current estimates, such amounts will be recorded as a cumulative adjustment in the period estimates are revised. The Company considers many factors when estimating expected forfeitures, including types of awards, employee class and historical experience. 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. See Note (10) Share-Based Payment Arrangements for additional information.


(o)	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’ equity. Gains and losses from foreign currency transactions are included in the consolidated statements of operations within interest and other income (loss), net.

During the years ended December 31, 2014, 2013 and 2012, foreign currency transactional losses totaled approximately $0.7 million, $1.1 million and $0.7 million, respectively.


(p)	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, restricted stock unit 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, 2014 and 2013:


		Year Ended December 31,
		2014			2013			2012
Stock options and restricted stock		7,800,293			8,150,032			11,532,032

(q)	Investments

As of December 31, 2014 and 2013, the Company did not have any cost-method investments. During December 2013, the Company sold its interest in Tianjin Zhongke Blue Whale Information Technologies Co., Ltd. (“Blue Whale”), a Chinese joint venture, for $3.0 million. The Company recorded a gain of $2.1 million within "interest and other (loss) income, net" in the accompanying consolidated statements of operations. During 2012, the Company recognized an impairment charge of approximately $11,000 related to certain of its cost-method investments as a result of other-than-temporary declines in market value related to certain of these investments. This charge is included within “interest and other (loss) income, net” in the accompanying consolidated statements of operations.


(r)	Treasury Stock

The Company accounts for treasury stock under the cost method and includes treasury stock as a component of stockholders’ equity.


(s)	Recently Adopted Accounting Pronouncements

In July 2013, the FASB issued new guidance which requires the netting of an unrecognized tax benefit, or a portion of an unrecognized tax benefit, against a deferred tax asset for a net operating loss carry forward, a similar tax loss, or a tax credit carry forward if such settlement is required or expected in the event the uncertain tax position is disallowed. The new guidance is effective prospectively to all existing unrecognized tax benefits, but entities can choose to apply it retrospectively. The adoption of this new accounting guidance in the first quarter of 2014 did not have any impact on the Company's consolidated financial position, results of operations or cash flows.

(t) Recently Issued Accounting Pronouncements

In November 2014, the FASB issued new guidance which requires an entity to determine whether the host contract in a hybrid financial instrument issued in the form of a share is more akin to debt or to equity by considering the economic characteristics and risks of the entire hybrid financial instrument, including the embedded derivative feature that is being evaluated for separate accounting from the host contract. The effects of initially adopting the amendments in this update should be applied on a modified retrospective basis to existing hybrid financial instruments issued in the form of a share as of the beginning of the fiscal year for which the amendments are effective. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015, which for the Company will be the annual period ending December 31, 2016. Early adoption, including adoption in an interim period, is permitted. The Company has not yet adopted this guidance and currently does not expect the adoption of the new guidance by the Company to have a significant impact on our financial results.

In August 2014, the FASB issued new guidance which requires an entity to evaluate whether there are conditions or events, in the aggregate, that raise substantial doubt about the entity's ability to continue as a going concern within one year after the date that the financial statements are issued (or within one year after the financial statements are available to be issued when applicable), and to provide related footnote disclosures in certain circumstances. The new standard is effective for the annual period ending after December 15, 2016, and for annual and interim periods thereafter, which for the Company will be the annual period ending December 31, 2016. Early application is permitted. The Company has not yet adopted this guidance and currently does not expect the adoption of the new guidance by the Company to have a significant impact on our financial results.

In May 2014, the FASB 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 will replace most existing revenue recognition guidance in Generally Accepted Accounting Principles in the United States when it becomes effective. The new standard is effective for the Company on January 1, 2017. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that this new guidance will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.

Fair_Value_Measurements

Fair Value Measurements	12 Months Ended
	Dec. 31, 2014
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. The Level 1 category includes money market funds and commercial paper, which at December 31, 2014 and 2013 totaled $2.0 million and $8.5 million, respectively, 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 Level 2 category includes government securities and corporate debt securities, which at December 31, 2014 and 2013 totaled $10.9 million and $8.1 million, respectively, which are included within “marketable securities” in the consolidated balance sheets.


	•	Level 3 – Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable. The Level 3 category includes derivatives, which at December 31, 2014 and 2013 totaled $0.1 million and $0.2 million, respectively, 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) income, 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, 2014 or 2013.

	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 verified 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.

	During 2014 and 2012, the Company recorded tax provisions of $0.5 million and $0.8 million, respectively, related to state and local and foreign taxes. During 2013, the Company recorded a tax benefit of $1.6 million primarily related to the reversal of unrecognized tax benefits of $2.3 million due to the expiration of applicable statutes of limitations partly offset by state and local and foreign taxes, withholding taxes on the gain on the sale of our cost-method investment and interest related to federal uncertain tax positions. In computing the 2012 tax provision, expenses related to certain legal matters were determined to be non-deductible for US income tax purposes.

	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:

During the years ended December 31, 2014 and 2013, the Company’s conclusion did not change with respect to its domestic deferred tax assets and, therefore, the Company has not recorded any benefit for its net domestic deferred tax assets for the full year 2014 or 2013. The reversal of the valuation allowance on deferred tax assets at December 31, 2014, would reduce income tax expense. As of December 31, 2014, the Company had federal net operating loss carryforwards of approximately $65.5 million which are set to expire beginning in 2030 through 2034, if not utilized.

As of December 31, 2014, the Company had approximately $1.1 million of various tax credit carryforwards, of which, approximately $0.6 million related to research and development tax credit carryforwards. The research and development tax credits may be carried forward 20 years for federal tax purposes and are set to expire at various dates beginning in 2020 through 2029, if not utilized. The Company has recorded a full valuation allowance against all such carryforwards as of December 31, 2014.

The Company has not provided for the United States income or additional foreign withholding taxes on approximately $3.8 million of undistributed earnings of its subsidiaries operating outside of the United States, with the exception of China. It is the Company’s practice and intention to reinvest those earnings permanently. Generally, such amounts become subject to United States taxation upon remittance of dividends and under certain other circumstances. Determination of the amount of any unrecognized deferred tax liability related to investments in these foreign subsidiaries is not practicable.

The effective tax rate before income taxes varies from the current statutory federal income tax rate as follows:

Tax at Federal statutory rate		$	(2,345,606	)		$	(4,377,225	)		$	(4,969,270	)

		$	510,091			$	(1,573,768	)		$	786,407


A reconciliation of the beginning and ending amount of unrecognized tax benefits, excluding interest and penalties, is as follows:

Balance at January 1,		$	217,237			$	2,085,484

Balance at December 31,		$	224,637			$	217,237


At December 31, 2014, $0.3 million including interest, if recognized, would reduce the Company’s annual effective tax rate. As of December 31, 2014, the Company had approximately $0.1 million of accrued interest. The Company does not expect any of its unrecognized tax benefits to reverse within the next 12 months.

The Company files federal, state, and foreign income tax returns in jurisdictions with varying statutes of limitations. The 2011 through 2014 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, South Korea, France and Germany.

Series_A_Redeemable_Convertibl

Series A Redeemable Convertible Preferred Stock	12 Months Ended
Series A Redeemable Convertible Preferred Stock	Dec. 31, 2014
Equity [Abstract]
Series A Redeemable Convertible Preferred Stock	Series A Redeemable Convertible Preferred Stock

	On September 16, 2013, the Company issued to Hale Capital Partners, LP (“Hale”) 900,000 shares of the Company’s newly created Series A redeemable convertible preferred stock (the "redeemable convertible preferred stock"), par value $0.001 per share, at a price of $10 per share, for an aggregate purchase consideration of $9.0 million. Hale subsequently assigned and transferred all of its shares of the redeemable convertible preferred stock to HCP-FVA LLC. Each share of redeemable convertible preferred stock is convertible into common stock equivalents, at the option of the holder and upon certain mandatory conversion events described below, at a conversion rate of $1.02488 (as adjusted for stock splits, stock dividends, reverse stock splits, stock combinations, reclassifications and similar events). The Company received net proceeds of approximately $8.7 million from the issuance of the redeemable convertible preferred stock in 2013, net of transaction costs.

	If the volume weighted average price of common stock for each trading day of any 60 consecutive trading days exceeds 250% of the conversion price and exceeds 225% of the conversion price through the conversion date, and certain equity conditions are met such that shares of common stock issued upon conversion can be immediately saleable by the redeemable convertible preferred stockholders, the Company can convert the redeemable convertible preferred stock up to an amount equal to the greater of 25% of the daily trading volume for the 20 consecutive trading days immediately preceding the conversion date or the amount of an identified bona fide block trade at a price reasonably acceptable to the applicable redeemable convertible preferred stockholder, but which price is not less than the arithmetic average of the weighted average prices of the common stock for the five trading days immediately preceding such sale.

	Upon certain triggering events, such as bankruptcy, insolvency or a material adverse effect, failure to achieve minimum financial covenants or failure of the Company to issue shares upon conversion of the Series A redeemable convertible preferred stock in accordance with its obligations, the Series A redeemable convertible preferred stockholders may require the Company to redeem all or some of the Series A redeemable convertible preferred stock at a price equal to the greater of 100% of the stated value plus accrued and unpaid dividends or the product of the number of shares of common stock underlying the Series A redeemable convertible preferred stock and the closing price as of the occurrence of the triggering event. On or after August 5, 2017, each Series A redeemable convertible preferred stockholder can require the Company to redeem its Series A redeemable convertible preferred stock in cash at a price equal to 100% of the stated value being redeemed plus accrued and unpaid dividends. If the Company does not have the funds necessary to redeem the Series A redeemable convertible preferred stock, the dividends accruing on any outstanding Series A redeemable convertible preferred stock will increase to prime plus 10% (from prime plus 5%). For each six months that the Series A redeemable convertible preferred stock remains unredeemed, the dividend rate increases by 1%, subject to a maximum dividend rate of 19%. In addition, the Company's failure to redeem the Series A redeemable convertible preferred stock would be considered a “Breach Event” under the agreements with the holders of the Series A redeemable convertible preferred stock. If a Breach Event were to occur and the Company is in default under or has breached any provision in respect of its obligations to redeem the Series A redeemable convertible preferred stock, then, under the agreements with the holders of our Series A redeemable convertible preferred stock, the Company's Board of Directors would automatically be increased, with the holders of the Series A redeemable convertible preferred stock having the right to appoint the new directors, so that the holders of the Series A redeemable convertible preferred stock would have appointed a majority of the Board of Directors. This would give the holders of the Series A redeemable convertible preferred stock control of the Company. As of December 31, 2014, the Company was not in compliance with the financial covenant based on EBITDA for two consecutive quarters, which provided the redeemable convertible preferred stockholders the right to require the Company to redeem any of the Series A redeemable convertible preferred stock at the greater of 100% of the stated value plus accrued and unpaid dividends or the product of the number of shares of common stock underlying the Series A redeemable convertible preferred stock and the closing price as of December 31, 2014. On February 5, 2015 the Company obtained a waiver from the holders of the Series A redeemable convertible preferred stock waiving the holders' rights arising from the EBITDA covenant violation as of December 31, 2014. Based on the Company's financial projections for 2015 the Company expects to be in compliance with the 2015 quarterly financial covenants as agreed to with the holders of the Series A redeemable convertible preferred stock. However, in the event the Company is unable to maintain compliance with the 2015 covenants, the Company intends to work with the holders of the Series A redeemable convertible preferred stock to obtain additional waivers, as necessary. As of December 31, 2014, the Company did not fail any other financial or non-financial covenants related to the Company's Series A redeemable convertible preferred stock. However, as described below, the Company accrued its dividend payment for the required quarterly dividends on the Series A redeemable convertible preferred stock for the fourth quarter of 2014.

	The Purchase Agreement for the redeemable convertible preferred stock provided that the Company would use commercially reasonable efforts to file a registration statement with the SEC within 90 days for the resale of all of the common stock issuable on the conversion of the Preferred Stock and as dividends. On December 2, 2013 the registration statement was declared effective by the Securities and Exchange Commission. The Purchase Agreement also contained other representations, warranties and financial and non-financial covenants, customary for an issuance of Preferred Stock in a private placement of this nature.

	Holders of the Series A redeemable convertible preferred stock are entitled to receive quarterly dividends at the Prime Rate (Wall Street Journal Eastern Edition) plus 5% (up to a maximum amount of 10%), payable in cash, provided, that if the Company will not have at least $1.0 million in positive cash flow for any calendar quarter after giving effect to the payment of such dividends, the Company, at its election, can pay such dividends in whole or in part in cash, provided that cash flow from operations is not negative, and the remainder can be accrued or paid in common stock to the extent certain equity conditions are satisfied. As of September 30, 2014, the Company was not in compliance with the cash flow requirement to pay dividends in cash which would have required the Company to pay these dividends in kind through additional shares of this Series A redeemable convertible preferred stock. However, on October 20, 2014, the Company obtained a waiver from the holders to allow the Company to pay the third quarter 2014 quarterly dividend in cash. In addition, as of December 31, 2014, due to the lack of sufficient surplus to pay dividends as required by the Delaware General Business Corporation Law, the Company was not permitted to pay the fourth quarter dividend in cash at this time and has accrued its fourth quarter 2014 dividend and expects to pay this dividend in the future in either cash or through the issuance of additional shares of common stock.

	Each share of redeemable convertible preferred stock has a vote equal to the number of shares of common stock into which the redeemable convertible preferred stock would be convertible as of the record date of September 13, 2013. The Company’s closing stock price on the record date was $1.23 per share which results in voting power of 7,317,073 shares. In addition, holders of a majority of the redeemable convertible preferred stock must approve certain actions, including any amendments to the Company's charter or bylaws that adversely affects the voting powers, preferences or other rights of the redeemable convertible preferred stock; payment of dividends or distributions; any liquidation, capitalization, reorganization or any other fundamental transaction of the Company; issuance of certain equity securities senior to or in parity with the redeemable convertible 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 capital stock of the Company.

	The Company has classified the redeemable convertible 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 preferred stock, the contingent redemption put options in the 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 redeemable convertible preferred stock and recorded as a liability. These derivative instruments were determined, in the aggregate, to have a fair value of $0.2 million at the time of issuance of the preferred stock and were recorded as a reduction to preferred stock. This discount is being accreted to the redeemable convertible 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. As of December 31, 2014 and 2013 the fair value of these derivative instruments was $0.1 million and $0.2 million, respectively. The gain on the change in fair value of these derivative instruments for 2014 and 2013 of $21,963 and $11,203, respectively, was included in “Interest and other (loss) income, net” within the consolidated statement of operations.

	A beneficial conversion feature (“BCF”) is recorded when the consideration allocated to a convertible security, divided by the number of common shares into which the security converts, is below the fair value of the common stock at the commitment date. The Company’s common stock price on the date one day prior to the closing of the Preferred Stock Agreement (the commitment date) was $1.23 per share, which was $0.21 greater than the conversion price of the redeemable convertible preferred stock. As the closing stock price on the commitment date was greater than the conversion price, the Company recognized a BCF, at the time of issuance. The Company allocated $2.0 million to the BCF through an increase to additional paid-in capital and a corresponding decrease to the preferred stock. The resulting additional discount to the preferred stock is also being accreted to the redeemable convertible 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.

	The Company included deductions of $0.5 million and $0.1 million as adjustments to net loss attributable to common stockholders on the statement of operations and in determining loss per share for the years ended December 31, 2014 and 2013, respectively. This represents the accretion for each year of the transaction costs of $0.3 million, BCF of $2.0 million and fair value allocated to the embedded derivatives of $0.2 million, recorded at the time of issuance. The Company also included deductions of $0.7 million and $0.2 million as adjustments to net loss attributable to common shareholders on the statement of operations and in determining loss per share for the years ended December 31, 2014 and 2013, respectively, for accrued dividends on the redeemable convertible preferred stock during the period. During 2014, the Company paid the cash dividends related to each of the first three quarters of 2014 on April 16, 2014, July 17, 2014 and October 21, 2014, respectively. However, due to the lack of sufficient surplus to pay dividends as required by the Delaware General Business Corporation Law, the Company accrued its fourth quarter 2014 dividend and expects to pay this dividend in the future in either cash or through the issuance of additional shares of common stock. The 2013 dividends were paid in cash on January 2, 2014.

	At various times from October 2001 through February 2009, the Company’s Board of Directors has authorized the repurchase of up to 14 million shares of the Company’s outstanding common stock in the aggregate. The repurchases may be made from time to time in open market transactions in such amounts as determined at the discretion of the Company’s management.

The Company did not recognize any tax benefits related to share-based compensation expense during the years ended December 31, 2014, 2013 and 2012.

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 either (i) the fair value per share at date of grant (directors, officers and employees), or (ii) the fair value per share as of each reporting period (non-employee consultants). 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,

		$	602,889			$	257,843			$	598,447


A summary of the Company’s restricted stock activity for 2014 is as follows:


		Number of Restricted Stock Awards
Non-Vested at December 31, 2013		605,600

Granted		2,107,857

Vested		(305,100	)
Forfeited		(75,000	)
Non-Vested at December 31, 2014		2,333,357


On April 1, 2014, the Company granted 2,037,857 shares of restricted stock to certain Company officers and employees. The restricted shares have terms of four years. The restrictions on various portions of the restricted stock lapse upon the Company's achievement of performance criteria related to: Common Stock price; GAAP earnings per share; non-GAAP earnings per share; cash related targets; and revenue/billings related targets. The restricted stock agreement contained a clause that provided the Company with discretion to recover the awards under certain circumstances. This discretion clause was amended on July 30, 2014 and as a result the grant date was determined to be July 30, 2014 in accordance with U.S. GAAP.

The fair value for awards related to the earnings per share, cash and revenue performance criteria is the closing stock price of the Company's common stock on the date of grant of $1.58. Share-based compensation expense for the performance criteria is recorded when the achievement of the performance condition is considered probable of achievement and is recorded straight-line 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 fair value of the common stock price market condition was calculated using the Monte Carlo simulation model resulting in a weighted average fair value of $0.80. Share-based compensation expense for the common stock price market condition is recorded straight-line over the longer of the explicit service period or the service period derived from the Monte Carlo simulation. The explicit service period and the service period derived from the Monte Carlo simulation were the same for the grant.

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, 2014, 2013 and 2012 was $0.5 million, $0.2 million and $1.1 million, respectively.

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/(benefit) 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,
		2014				2013				2012
Non-qualified stock options		$	1,173			$	37,379			$	13,999

Restricted stock awards		—				—				13,488

		$	1,173			$	37,379			$	27,487


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, 2014, 2013 and 2012. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by the employees who receive equity awards.

The per share weighted average fair value of share-based payments granted during the years ended December 31, 2014, 2013 and 2012 was $1.26, $0.84 and $1.36, respectively. In addition to the exercise and grant date prices of the awards, certain weighted average assumptions that 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,
		2014		2013		2012
Expected dividend yield		0%		0%		0%
Expected volatility		55 - 57%		61 - 64%		60 - 61%
Risk-free interest rate		1.20 - 1.84%		0.84 - 1.64%		0.7 - 1.2%
Expected term (years)		3.4 - 5.5		5.5		5.5
Discount for post-vesting restrictions		N/A		N/A		N/A

Options granted to officers, employees and directors during fiscal 2014, 2013, and 2012 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. Based on each respective group’s historical vesting experience and expected trends, the estimated forfeiture rate for officers, employees, and directors, as adjusted, for both fiscal years 2014 and 2013 was 30%, 30% and 0%, respectively. For fiscal year 2012, the estimated forfeiture rate for officers, employees, and directors, as adjusted, was 11%, 24% and 0%, respectively. The impact of the change in the forfeiture rates from 2012 to 2013 was a reduction to share-based compensation expense of $0.1 million.

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, 2014, there was approximately $1.5 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 1.82 years.

As of December 31, 2014, the Company had 11,806,745 shares of common stock reserved for issuance upon the exercise of stock options, restricted stock and restricted stock units.

	The Company has an operating lease covering its corporate office facility that expires in April 2021. The Company also has several additional operating leases related to offices in foreign countries. The expiration dates for these leases range from 2015 through 2017. The following is a schedule of future minimum lease payments for all operating leases as of December 31, 2014:


	2015	$	2,308,795

	2016	1,804,870

	2019	1,502,966

	Thereafter	2,074,369

		$	10,756,162


	These leases require the Company to pay its proportionate share of real estate taxes and other common charges. Total rent expense for operating leases was $3.0 million, $3.3 million and $3.2 million for the years ended December 31, 2014, 2013 and 2012, respectively.

	The Company typically provides its customers a warranty on its software products for a period of no more than 90 days. Such warranties are accounted for in accordance with the authoritative guidance issued by the FASB on contingencies. For the year ended December 31, 2014, the Company has not incurred any costs related to warranty obligations.

	Under the terms of substantially all of its software license agreements, the Company has agreed to indemnify its customers for all costs and damages arising from claims against such customers based on, among other things, allegations that the Company’s software infringes the intellectual property rights of a third party. In most cases, in the event of an infringement claim, the Company retains the right to (i) procure for the customer the right to continue using the software; (ii) replace or modify the software to eliminate the infringement while providing substantially equivalent functionality; or (iii) if neither (i) nor (ii) can be reasonably achieved, the Company may terminate the license agreement and refund to the customer a pro-rata portion of the license fee paid to the Company. Such indemnification provisions are accounted for in accordance with the authoritative guidance issued by the FASB on guarantees. From time to time, in the ordinary course of business, the Company receives claims for indemnification, typically from OEMs. The Company is not currently aware of any material claims for indemnification.

	Upon certain triggering events, such as bankruptcy, insolvency or a material adverse effect, failure to achieve minimum financial covenants or failure of the Company to issue shares upon conversion of the redeemable convertible preferred stock in accordance with its obligations, the redeemable convertible preferred stockholders may require the Company to redeem all or some of the redeemable convertible preferred stock at a price equal to the greater of 100% of the stated value plus accrued and unpaid dividends or the product of the number of shares of common stock underlying the redeemable convertible preferred stock and the closing price as of the occurrence of the triggering event. On or after August 5, 2017, each redeemable convertible preferred stockholder can require the Company to redeem its redeemable convertible preferred stock in cash at a price equal to 100% of the stated value being redeemed plus accrued and unpaid dividends. As of December 31, 2014, the Company was not in compliance with the financial covenant based EBITDA for two consecutive quarters which, provided the redeemable convertible preferred stockholders the right to require the Company to redeem any of the redeemable convertible preferred stock for the greater of 100% of the stated value plus accrued and unpaid dividends or the product of the number of shares of common stock underlying the Series A redeemable convertible preferred stock and the closing price as of December 31, 2014. On February 5, 2015 the Company obtained a waiver from the holders of the Series A redeemable convertible preferred stock waiving the holders' rights arising from the EBITDA covenant violation as of December 31, 2014. Based on the Company's financial projections for 2015 the Company expects to be in compliance with the 2015 quarterly financial covenants as agreed to with the holders of the Series A redeemable convertible preferred stock. However, in the event the Company is unable to maintain compliance with the 2015 covenants, the Company intends to work with the holders of the Series A redeemable convertible preferred stock to obtain additional waivers, as necessary. As of December 31, 2014, the Company did not fail any other financial or non-financial covenants related to the Company's Series A redeemable convertible preferred stock. However, as described under Note (13), Redeemable Convertible Preferred Stock, the Company accrued its dividend payment for the required quarterly dividends on the Series A redeemable convertible preferred stock for the fourth quarter of 2014.

	On July 23, 2013, the Company entered into an Employment Agreement (“Quinn Employment Agreement”) with Gary Quinn. Pursuant to the Quinn Employment Agreement, the Company agreed to employ Mr. Quinn as President and Chief Executive Officer of the Company effective July 23, 2013 through July 22, 2015, at an annual salary of $0.4 million per annum. The Quinn Employment Agreement also provided for the grant of 500,000 restricted shares which will vest over a two year period at 50% and 50% annually. The 500,000 restricted shares were granted to Mr. Quinn by the Company’s Compensation Committee on August 5, 2013. As of December 31, 2014, 250,000 restricted shares remain unvested.

	From time to time, the Company has undertaken restructuring and expense control measures to support its business performance and to align the Company’s cost structure with its resources. During the third quarter of 2013, the Company adopted a restructuring plan intended to better align the Company’s cost structure with the skills and resources required to more effectively execute the Company’s long-term growth strategy and to support revenue levels the Company expects to achieve on a go forward basis. In connection with the 2013 Plan the Company eliminated over 100 positions worldwide, implemented tighter expense controls, ceased non-core activities and closed or downsized several facilities. As of December 31, 2014 the restructuring accrual totaled $1.0 million. The remaining payments under the 2013 Plan are expected to be paid through the first half of 2015; however, there can be no assurance that all payments will be completed by that time.

	On December 1, 2005, the Company adopted the 2005 FalconStor Software, Inc., Key Executive Severance Protection Plan, which was amended April 1, 2014 (“Severance Plan”). Pursuant to the Severance Plan, the Company’s Chief Executive Officer, Chief Financial Officer and certain other key personnel are entitled to receive certain contingent benefits, as set forth in the Severance Plan, including lump sum payments and acceleration of stock option vesting, each in certain circumstances.

	In addition, as of December 31, 2014, our liability for uncertain tax positions totaled $0.3 million.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments

	The Company from time to time will use derivative financial instruments, such as foreign currency forward contracts, as economic hedges to reduce exchange rate risks arising from the change in fair value of certain foreign currency denominated assets and liabilities (i.e., receivables and payables). The purpose of the Company’s foreign currency risk management program is to reduce volatility in earnings caused by exchange rate fluctuations. In accordance with the authoritative guidance issued by the FASB on derivatives and hedging, companies are required to recognize all of the derivative financial instruments as either assets or liabilities at fair value in their balance sheets. The Company does not use derivative financial instruments for trading or speculative purposes.

	As of December 31, 2014, 2013 and 2012, the Company had no foreign currency forward contracts outstanding. The Company did not utilize foreign currency forward contracts during the years ended December 31, 2014, 2013 and 2012.

	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. These derivative instruments were determined, in the aggregate, to have a fair value of $0.2 million at the time of issuance of the Series A redeemable convertible preferred stock and were recorded as a reduction to preferred stock. As of December 31, 2014 and 2013, the fair value of these derivative instruments was $0.1 million and $0.2 million, respectively. The gain on the change in fair value of these derivative instruments for the years ended December 31, 2014 and 2013 of $21,963 and $11,203, respectively, was included in “Interest and other (loss) income, net” within the consolidated statement of operations.

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.

	Stockholder Litigation

	Company stockholders filed actions in the Suffolk County Division of the Supreme Court of the State of New York, putatively derivatively on behalf of the Company, against the Company, each of the Company’s Directors, Mr. Weber, the former Chief Financial Officer and Vice President of Operations of the Company, Wayne Lam, a former Vice president of the Company, the estate of Mr. Huai, the former Chairman, President and Chief Executive Officer of the Company, and Jason Lin, a former employee of the Company (the “Derivative Action”). The consolidated amended Derivative Action complaint alleged that the defendants breached their duties to the Company by: (1) causing or allowing the dissemination of false and misleading information; (2) failing to maintain internal controls; (3) failing to manage the Company properly; (4) unjustly enriching themselves; (5) abusing their control of the Company; and (6) wasting Company assets.

	On March 5, 2013, the Suffolk County Division of the Supreme Court of the State of New York granted a motion made by all of the defendants in the Derivative Action, except Mr. Lin, and dismissed the Derivative Action as to all defendants other than Mr. Lin. The stockholders have appealed the dismissal of the Derivative Action. All documents relating to the appeal have been filed with the court and oral argument was made on January 26, 2015. The Company is currently awaiting a decision from the court. The Company cannot predict when the appeal will be resolved or the ultimate outcome of the matter. Certain of the defendants may be entitled to indemnification by the Company under the laws of Delaware and/or the Company’s by-laws.

	The Company has insurance policies that were purchased to cover, among other things, lawsuits like the Derivative Action and a class action lawsuit that has been settled by the Company ("Class Action"). The Company’s Directors and Officers (“D&O”) Insurance, is composed of more than one layer, with each layer written by a different insurance company. However, the events that gave rise to the claims in the Derivative Action and Class Action caused the Company’s insurers to reserve their rights to disclaim, rescind, or otherwise not be obligated to provide coverage to the Company and certain other insureds under the policies. In light of these uncertainties, the Company entered into settlements with two of its insurers. Pursuant to these settlements, the Company did not receive repayment of all amounts it might otherwise have received.

	In October 2012 the Company entered into an agreement with the carrier of the first $5.0 million layer of the Company’s D&O insurance. Pursuant to this agreement, the Company accepted a payment of $3.9 million from the first layer insurance carrier in 2012 in satisfaction of the carrier’s obligations to the Company under the first layer D&O insurance policy. In addition, as part of the October 2012 agreement with the carrier, the Company agreed to indemnify the carrier of the first layer of D&O insurance against potential claims by certain named insured persons under the first layer D&O insurance policy. The Company cannot predict the likelihood or the outcome of any such claims by the named insureds.

	Because the carrier of the next layer of insurance would not be obligated to make payment to the Company until the full $5.0 million first layer limit had been exhausted, this means that the Company was responsible for $1.1 million out of pocket before it could again seek reimbursement from its insurers. The Company accrued for the $1.1 million during 2012.

	On July 31, 2013 the Company entered into an agreement with the carrier of the second $5.0 million layer of the Company’s D&O insurance. Pursuant to the agreement, the insurer agreed to pay seventy five percent (75%) of the Company’s losses attributable to the Class Action and the Derivative Action above the first $5.25 million of such losses. In addition, as part of the July 31, 2013 agreement with the carrier, the Company agreed to indemnify the carrier of the second layer of D&O insurance against potential claims by certain named insured persons under the second layer D&O insurance policy. The Company cannot predict the likelihood or the outcome of any such claims by the named insureds.

	While, at present, the Company does not believe that the amounts it will pay in connection with the Class Action and the Derivative Action will exceed the limits of the first two layers of its coverage, there can be no assurance that if the Company seeks recovery from the additional layers, the recovery the Company makes on the remainder of its insurance will be adequate to cover the costs of its defense or settlement of the Derivative Action, or any damages that might ultimately be awarded against the Company or anyone to whom the Company might owe indemnification if the appeal is successful.

	The Company’s remaining insurers may deny coverage under the policies. If the plaintiffs are awarded damages and the Company’s insurance is not adequate to cover the amounts, or its insurers deny coverage, the amounts to be paid by the Company could have a significant negative impact on its financial results, cash flow and cash balances.

	Since October 1, 2012, the Company has recorded $7.3 million of total costs associated with the Class Action and the Derivative Actions. As a result of the agreement reached with the insurer carriers of the Company’s D&O insurance, the Company recorded insurance recoveries of $5.6 million since October 1, 2012 all of which has been reimbursed by the Company’s insurance carriers as of December 31, 2014.

	The Estate of ReiJane Huai

	On June 12, 2014, the Company entered into an agreement to settle the action it filed against the Estate of ReiJane Huai (the “Estate”) in Surrogates Court, Nassau County, State of New York. Mr. Huai was the former Chairman, President and Chief Executive Officer of the Company. The Company believed that prior to entering into the settlement agreement, the Estate owned more than 10% of the voting stock of the Company.
	Effective June 27, 2014, pursuant to the settlement agreement, the Estate transferred 3,132,141 shares of the Company's common stock to the Company and the shares were transferred to the Company's treasury account and recognized a gain of $5.3 million. The Company has recorded these shares within treasury. On July 16, 2014, in accordance with the settlement agreement, the Company’s action against the Estate was voluntarily discontinued. The settlement agreement also contained various other terms and conditions. Among the other terms of the agreement were the following:


	•	The Company agreed to register for resale, by the Estate, the remaining shares of the Company's common stock formerly registered in the name of Mr. Huai.

	•	The Company has a right of first refusal to purchase the remaining shares of the Company's common stock held by the Estate if the Estate proposes to dispose of such shares in any private transactions.

	•	Any shares of FalconStor stock held by the Estate are subject to a five-year voting agreement that requires the Estate to vote the shares in accordance with the recommendations of the Company’s Board of Directors.

	In September 2014, the Estate informed the Company that it had an agreement for the sale of 600,000 shares of the Company's common stock in a private transaction. In accordance with its rights under the Settlement Agreement, the Company assigned its right of first refusal to purchase those shares to an unrelated third party.

	In November 2014, the Company entered into a purchase agreement to acquire 4,298,533 shares of the Company's common stock held by the Estate for $4.7 million and recorded these shares in treasury. See Note (9) Stockholders' Equity to our consolidated financial statements for further information.

	In December 2014, the Estate informed the Company that it had an agreement for the sale of the remaining 600,000 shares of the Company's common stock in a private transaction. In accordance with its rights under the Settlement Agreement, the Company assigned its right of first refusal to purchase those shares to an unrelated third party.

	During 2014 and 2013, the Company recorded a benefit of $5.4 million and an expense of $0.4 million, respectively, of investigation, litigation and settlement related legal costs, net of expected recoveries, related to expenses related to the Class Action and Derivative Action lawsuits, the Estate settlement and other settlement related activities that are not recoverable through insurance.

	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.

	From time to time, the Company has undertaken restructuring and expense control measures to support its business performance and to align the Company’s cost structure with its resources. In the third quarter of 2013, the Company adopted the 2013 Plan to better align the Company’s cost structure with the skills and resources required to more effectively execute the Company’s long-term growth strategy and to support revenue levels the Company expects to achieve on a go forward basis. In connection with the 2013 Plan, the Company eliminated over 100 positions worldwide, implemented tighter expense controls, ceased non-core activities and closed or downsized several facilities. Actions under the 2013 Plan were completed as of December 31, 2014, except for certain payments under the 2013 Plan that are expected to be paid through 2015. There can be no assurance that all payments will be completed by that time. The total amount incurred under the 2013 Plan for the years ended December 31, 2014 and 2013, was $1.1 million and $3.6 million, respectively.

	In July 2012, the Company undertook certain restructuring activities that included a workforce reduction of approximately 35 positions worldwide (the “2012 Plan”). These actions were intended to better align the Company’s cost structure with the skills and resources required to more effectively execute the Company’s long-term growth strategy and to support the anticipated revenue levels we expect to achieve on a go forward basis. The total amount incurred with respect to severance under the 2012 Plan was $0.8 million. Actions under the 2012 Plan were substantially completed during the third quarter of 2012.

	Accrued restructuring costs as of December 31, 2014 associated with the 2013 Plan is as follows:

	Defined Contribution Plan

	Effective July 2002, the Company established a voluntary savings and defined contribution plan (the “Plan”) under Section 401(k) of the Internal Revenue Code. This Plan covers all U.S. employees meeting certain eligibility requirements and allows participants to contribute a portion of their annual compensation. Employees are 100% vested in their own contributions. For the years ended December 31, 2014, 2013 and 2012, the Company did not make any contributions to the Plan.

	Effective July 1, 2007, the Company, in accordance with the labor pension system in Taiwan, contributes 6% of salaries to individual pension accounts managed by the Bureau of Labor Insurance. The plan covers all Taiwan employees that elect the new pension system and all employees hired after July 1, 2005. For the years ended December 31, 2014, 2013 and 2012, the Company contributed approximately $97,000, $115,000 and $127,000, respectively.

	Defined Benefit Plan

	The Company has a defined benefit plan covering employees in Taiwan. The Company accounts for its defined benefit plan in accordance with the authoritative guidance issued by the FASB on retirement benefits, which requires the Company to recognize the funded status of its defined benefit plan in the accompanying consolidated balance sheet, with the corresponding adjustment to accumulated other comprehensive income, net of tax.

	At December 31, 2014 and 2013, $26,613 and $(71,892), respectively, is included in accumulated other comprehensive income (loss) for amounts that have not yet been recognized in net periodic pension cost. These amounts include the following: unrecognized transition obligation of $21,590 and $28,551 at December 31, 2014 and 2013, respectively, and unrecognized actuarial (gain) loss of $(48,203) and $43,341 at December 31, 2014 and 2013, respectively. During 2014, the total amount recorded in other comprehensive income related to the pension plan was $98,505 (net of tax), which consisted of an actuarial gain of $93,107 and the recognition of $5,398 of transition obligations recognized during 2014 as a component of net periodic pension cost. The transition obligation and actuarial loss included in accumulated other comprehensive loss and expected to be recognized in net periodic pension cost for the year ended December 31, 2015, is $5,657 and $754 respectively.

Summary of Significant Accounting Policies (Policies)	Dec. 31, 2014
Organization, Consolidation and Presentation of Financial Statements [Abstract]
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.
Reclassifications	Reclassifications

	Certain prior year’s amounts have been reclassified to conform to the current year presentation.
Use of Estimates	Use of Estimates

	The preparation of financial statements in conformity with generally accepted accounting principles 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, marketable securities, valuation of embedded derivatives, software development costs, goodwill and other intangible assets and income taxes. Actual results could differ from those estimates.

	The financial market volatility, both in the U.S. and in many other countries where the Company operates, has impacted and may continue to impact the Company’s business. Such conditions could have a material impact to the Company’s significant accounting estimates discussed above.
Cash Equivalents, Restricted Cash and Marketable Securities	Cash Equivalents, Restricted Cash and Marketable Securities

	The Company considers all highly liquid investments with maturities of three months or less when purchased to be cash equivalents. The Company records its cash equivalents and marketable securities at fair value in accordance with the authoritative guidance issued by the Financial Accounting Standards Board (“FASB”) on fair value measurements and disclosures. As of December 31, 2014 the Company’s cash equivalents consisted of money market funds. As of December 31, 2013, the Company’s cash equivalents consisted of money market funds and commercial paper. At December 31, 2014 and 2013, the fair value of the Company’s cash equivalents amounted to approximately $2.0 million and $8.5 million, respectively.

	As of December 31, 2013, the Company had $0.8 million of restricted cash. The restricted cash served as collateral related to deposit service indebtedness with the Company’s commercial bank. During 2014, this cash was released by the company's commercial bank and is no longer considered restricted cash.

	As of December 31, 2014 and 2013, the Company’s marketable securities consisted of corporate bonds and government securities. As of December 31, 2014 and 2013, the fair value of the Company’s marketable securities was approximately $10.9 million and $8.1 million, respectively. All of the Company’s marketable securities are classified as available-for-sale, and accordingly, unrealized gains and losses on marketable securities, net of tax, are reflected as a component of accumulated other comprehensive loss in stockholders’ equity. Any other-than-temporary impairments are recorded within interest and other (loss) income, net in the consolidated statement of operations. See Note (4) Marketable Securities for additional information.
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, 2014 and 2013, 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.
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 FASB 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	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 and as stand-alone software applications. 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 and 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 customers typically send the Company a purchase order when they have an end user identified. Distributor customers typically send the Company a purchase order when they have a reseller and an end user identified. For bundled arrangements that include either maintenance or both maintenance and professional services, the Company uses the residual method to determine the amount of product revenue to be recognized. Under the residual method, consideration is allocated to the undelivered elements based upon vendor-specific objective evidence (“VSOE”) of the fair value of those elements, with the residual of the arrangement fee allocated to and recognized as product revenue. If VSOE does not exist for all undelivered elements of an arrangement, the Company recognizes total revenue from the arrangement ratably over the term of the maintenance agreement. The Company's long-term portion of deferred revenue consists of (i) payments received for maintenance contracts with terms in excess of one year as of the balance sheet date, (ii) payments received for product sales bundled with multiple years of maintenance but for which VSOE did not exist for all undelivered elements of the arrangement, and (iii) payments received in connection with a joint development agreement entered into by the Company in 2013 pursuant to which certain revenue was deferred until final delivery and acceptance of the final software. The Company provides an allowance for product returns as a reduction of revenue, based upon historical experience and known or expected trends.

	Revenues associated with maintenance services are deferred and recognized as revenue ratably over the term of the contract. Revenues associated with software implementation and software engineering services are recognized when the services are performed. Costs of providing these services are included in cost of support and services.

	The Company has entered into various distribution, licensing and joint promotion agreements with OEMs, whereby the Company has provided to the OEM a non-exclusive software license to install the Company’s software on certain hardware or to resell the Company’s software in exchange for payments based on the products distributed by these OEMs. Such payments from the OEM or distributor are recognized as revenue in the period reported by the OEM.

	From time to time the Company will enter into funded software development arrangements. Under such arrangements, revenue recognition will not commence until final delivery and/or acceptance of the product. For arrangements where the Company has VSOE for the undelivered elements, the Company will follow the residual method and recognize product revenue upon final delivery and/or acceptance of the product. For arrangements where the Company does not have VSOE for the undelivered elements, the Company will recognize the entire arrangement fee ratably commencing at the time of final delivery and/or acceptance through the end of the service period in the arrangement. Certain arrangements, for which VSOE of fair value for the undelivered maintenance elements cannot be established, are accounted for as a single unit of accounting. The revenue recognized from single units of accounting are typically allocated and classified on the consolidated statements of operations as product revenue and support and services revenue. Since VSOE cannot be established, VSOE of similar maintenance offerings provides the basis for the support and services revenue classification, and the remaining residual consideration provides the basis for the product revenue classification. Final acceptance of the software delivered under the joint development agreement occurred on November 16, 2014. Therefore the Company will recognize the total committed fee as revenue ratably over a twenty-five and a half month period which began on November 16, 2014 and includes the contractual twenty-four month maintenance period. As of December 31, 2014, the Company recorded product revenue of approximately $0.6 million and maintenance revenue of approximately $0.2 million related to this agreement. As of December 2014, the Company recorded short term deferred revenue of $5.6 million and long term deferred revenue of $5.6 million, related to this agreement. If at any time, the customer elects to terminate their maintenance agreement, any unrecognized deferred revenue would be accelerated and recognized as revenue during the period in which the termination becomes effective.
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 during the fourth quarter of each year, and the Company has determined there to be no impairment for any of the periods presented. Based on the Company’s analysis, the fair value of its reporting unit substantially exceeds the carrying value of its goodwill balances as of December 31, 2014 and 2013. 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. See Note (6) Income Taxes for additional information.
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

	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 estimated 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 straight-line 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 straight-line over the longer of the explicit service period or the service period derived from the Monte Carlo simulation. The estimation of share-based awards that will ultimately vest requires judgment, and to the extent actual results or updated estimates differ from the Company’s current estimates, such amounts will be recorded as a cumulative adjustment in the period estimates are revised. The Company considers many factors when estimating expected forfeitures, including types of awards, employee class and historical experience. 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. See Note (10) Share-Based Payment Arrangements for additional information.
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’ equity. Gains and losses from foreign currency transactions are included in the consolidated statements of operations within interest and other income (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, restricted stock unit awards and Series A redeemable convertible preferred stock outstanding.
Investments	Investments

	As of December 31, 2014 and 2013, the Company did not have any cost-method investments. During December 2013, the Company sold its interest in Tianjin Zhongke Blue Whale Information Technologies Co., Ltd. (“Blue Whale”), a Chinese joint venture, for $3.0 million. The Company recorded a gain of $2.1 million within "interest and other (loss) income, net" in the accompanying consolidated statements of operations. During 2012, the Company recognized an impairment charge of approximately $11,000 related to certain of its cost-method investments as a result of other-than-temporary declines in market value related to certain of these investments. This charge is included within “interest and other (loss) income, net” in the accompanying consolidated statements of operations.
Treasury Stock	Treasury Stock

	The Company accounts for treasury stock under the cost method and includes treasury stock as a component of stockholders’ equity.
Recently Adopted Accounting Pronouncements/Recently Issued Accounting Pronouncements	Recently Adopted Accounting Pronouncements

	In July 2013, the FASB issued new guidance which requires the netting of an unrecognized tax benefit, or a portion of an unrecognized tax benefit, against a deferred tax asset for a net operating loss carry forward, a similar tax loss, or a tax credit carry forward if such settlement is required or expected in the event the uncertain tax position is disallowed. The new guidance is effective prospectively to all existing unrecognized tax benefits, but entities can choose to apply it retrospectively. The adoption of this new accounting guidance in the first quarter of 2014 did not have any impact on the Company's consolidated financial position, results of operations or cash flows.

	(t) Recently Issued Accounting Pronouncements

	In November 2014, the FASB issued new guidance which requires an entity to determine whether the host contract in a hybrid financial instrument issued in the form of a share is more akin to debt or to equity by considering the economic characteristics and risks of the entire hybrid financial instrument, including the embedded derivative feature that is being evaluated for separate accounting from the host contract. The effects of initially adopting the amendments in this update should be applied on a modified retrospective basis to existing hybrid financial instruments issued in the form of a share as of the beginning of the fiscal year for which the amendments are effective. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015, which for the Company will be the annual period ending December 31, 2016. Early adoption, including adoption in an interim period, is permitted. The Company has not yet adopted this guidance and currently does not expect the adoption of the new guidance by the Company to have a significant impact on our financial results.

	In August 2014, the FASB issued new guidance which requires an entity to evaluate whether there are conditions or events, in the aggregate, that raise substantial doubt about the entity's ability to continue as a going concern within one year after the date that the financial statements are issued (or within one year after the financial statements are available to be issued when applicable), and to provide related footnote disclosures in certain circumstances. The new standard is effective for the annual period ending after December 15, 2016, and for annual and interim periods thereafter, which for the Company will be the annual period ending December 31, 2016. Early application is permitted. The Company has not yet adopted this guidance and currently does not expect the adoption of the new guidance by the Company to have a significant impact on our financial results.

	In May 2014, the FASB 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 will replace most existing revenue recognition guidance in Generally Accepted Accounting Principles in the United States when it becomes effective. The new standard is effective for the Company on January 1, 2017. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that this new guidance will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.

Warranty on software products	Under the terms of substantially all of its software license agreements, the Company has agreed to indemnify its customers for all costs and damages arising from claims against such customers based on, among other things, allegations that the Companybs software infringes the intellectual property rights of a third party. In most cases, in the event of an infringement claim, the Company retains the right to (i) procure for the customer the right to continue using the software; (ii) replace or modify the software to eliminate the infringement while providing substantially equivalent functionality; or (iii) if neither (i) nor (ii) can be reasonably achieved, the Company may terminate the license agreement and refund to the customer a pro-rata portion of the license fee paid to the Company. Such indemnification provisions are accounted for in accordance with the authoritative guidance issued by the FASB on guarantees. From time to time, in the ordinary course of business, the Company receives claims for indemnification, typically from OEMs. The Company is not currently aware of any material claims for indemnification.
