Accounting Policies [Abstract]
Organization and Description of Business	Note 1. Organization and Description of Business Organization and Description of Business Spherix Incorporated (the “Company”) is an intellectual property company incorporated in the State of Delaware that owns patented and unpatented intellectual property. The Company was formed in 1967 as a scientific research company and for much of its history pursued drug development including through Phase III clinical studies which were discontinued. Through the Company’s acquisition of patents and patent applications developed by Nortel Networks Corporation from Rockstar Consortium US, LP (“Rockstar”) and Harris Corporation from North South Holdings Inc. (“North South”) in 2013, the Company has expanded its activities. The Company is currently a patent commercialization company focused on generating revenues from the monetization of intellectual property, or IP. Such monetization includes, but is not limited to, acquiring IP from patent holders in order to maximize the value of the patent holdings by conducting and managing a licensing campaign, or through the settlement and litigation of patents. We intend to generate revenues and related cash flows from the granting of intellectual property rights for the use of patented technologies that we own, that we manage for others, or that others manage on our behalf. To date, we have generated minimal revenues and no assurance can be provided that our business model will be successful. The Company continually works to enhance its portfolio of intellectual property through acquisitions and strategic partnerships. The Company’s mission is to partner with inventors, or other entities, who own undervalued intellectual property. The Company then works with the inventors or other entities to commercialize the IP. In March 2016, the Company entered into an agreement (which was subsequently amended in April and May 2016) with Equitable IP Corporation (“Equitable”) to facilitate the monetization of its patents (the “Monetization Agreement”). Pursuant to the Monetization Agreement, the Company is working together with Equitable to further develop and revise its ongoing litigation plan. See Note 4 for additional details surrounding the Monetization Agreement.

Notes to Financial Statements
Liquidity and Financial Condition	Note 2. Liquidity and Financial Condition The Company continues to incur ongoing administrative and other expenses, including public company expenses, in excess of corresponding (non-financing related) revenue. While the Company continues to implement its business strategy, it intends to finance its activities through: ● managing current cash and cash equivalents on hand from the Company’s past debt and equity offerings, ● seeking additional funds raised through the sale of additional securities in the future, ● seeking additional liquidity through credit facilities or other debt arrangements, and ● increasing revenue from its patent portfolios, license fees and new business ventures. Management believes the Company currently has sufficient funds to meet its operating requirements for at least the next twelve months. The Company’s ultimate success is dependent on its ability to obtain additional financing and generate sufficient cash flow to meet its obligations on a timely basis. The Company’s business will require significant amounts of capital to sustain operations and make the investments it needs to execute its longer term business plan. The Company’s working capital amounted to approximately $2.8 million at March 31, 2017, and net loss amounted to approximately $1.0 million for the three months ended March 31, 2017. The Company had an approximately $142.7 million of accumulated deficit as of March 31, 2017. Absent generation of sufficient revenue from the execution of the Company’s long term business plan, the Company will need to obtain additional debt or equity financing, especially if the Company experiences downturns in its business that are more severe or longer than anticipated, or if the Company experiences significant increases in expense levels resulting from being a publicly-traded company or operations. If the Company attempts to obtain additional debt or equity financing, the Company cannot assume that such financing will be available to the Company on favorable terms, or at all. Disputes regarding the assertion of patents and other intellectual property rights are highly complex and technical. The Company may be forced to litigate against others to enforce or defend its intellectual property rights or to determine the validity and scope of other parties’ proprietary rights. The defendants or other third parties involved in the lawsuits in which the Company is involved may allege defenses and/or file counterclaims or initiate inter parties reviews in an effort to avoid or limit liability and damages for patent infringement or cause the Company to incur additional costs as a strategy. If such efforts are successful, they may have an impact on the value of the patents and preclude the Company from deriving revenue from the patents. The patents could be declared invalid by a court or the United States Patent and Trademark Office, in whole or in part, or the costs of the Company can increase. Recent rulings also create an increased risk that if the Company is unsuccessful in litigation it could be responsible to pay the attorneys’ fees and other costs of defendants by lowering the standard for legal fee shifting sought by defendants in patent cases.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 3. Summary of Significant Accounting Policies Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Nuta Technology Corp. (“Nuta”), Spherix Portfolio Acquisition II, Inc. (“SPXII”), Guidance IP, LLC (“Guidance”), Directional IP, LLC (“Directional”), Spherix Management Services, LLC (“SMS”) and NNPT, LLC (“NNPT”). All significant intercompany balances and transactions have been eliminated in consolidation. Use of Estimates The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“US GAAP”). This requires management to make estimates and assumptions that affect certain reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the period. The Company’s significant estimates and assumptions include the recoverability and useful lives of long-lived assets, stock-based compensation, the valuation of derivative liabilities, and the valuation allowance related to the Company’s deferred tax assets. Certain of the Company’s estimates, including the carrying amount of the intangible assets, could be affected by external conditions, including those unique to the Company and general economic conditions. It is reasonably possible that these external factors could have an effect on the Company’s estimates and could cause actual results to differ from those estimates and assumptions. Marketable Securities Marketable securities are classified as trading and are carried at fair value. The Company’s marketable securities consist of corporate bonds and highly liquid mutual funds and exchange-traded & closed-end funds which are valued at quoted market prices. During the three months ended March 31, 2017 and 2016, the Company incurred realized losses of approximately $93,000 and $66,000, respectively, and unrealized gains of approximately $72,000 and $12,000, respectively, on its investments in marketable securities, which are included in other income, net on the consolidated statements of operations. In addition, during the three months ended March 31, 2017 and 2016, the Company earned dividend income of approximately $8,000 and $13,000, respectively, which is included in other income, net on the consolidated statement of operations. The Company reinvested such dividend income into its marketable securities during the three months ended March 31, 2017 and 2016. The market value of marketable securities held as of March 31, 2017 and December 31, 2016 were $5.1 million and $6.0 million, respectively. Accounting for Warrants The Company accounts for the issuance of common stock purchase warrants issued in connection with the equity offerings in accordance with the provisions of ASC 815, Derivatives and Hedging (“ASC 815”). The Company classifies as equity any contracts that (i) require physical settlement or net-share settlement or (ii) gives the Company a choice of net-cash settlement or settlement in its own shares (physical settlement or net-share settlement). The Company classifies as assets or liabilities any contracts that (i) require net-cash settlement (including a requirement to net-cash settle the contract if an event occurs and if that event is outside the control of the Company) or (ii) gives the counterparty a choice of net-cash settlement or settlement in shares (physical settlement or net-share settlement). In addition, Under ASC 815, registered common stock warrants that require the issuance of registered shares upon exercise and do not expressly preclude an implied right to cash settlement are accounted for as derivative liabilities. The Company classifies these derivative warrant liabilities on the consolidated balance sheet as a current liability. The Company assessed the classification of common stock purchase warrants as of the date of each offering and determined that such instruments met the criteria for liability classification. Accordingly, the Company classified the warrants as a liability at their fair value and adjusts the instruments to fair value at each reporting period. This liability is subject to re-measurement at each balance sheet date until the warrants are exercised or expired, and any change in fair value is recognized as “change in the fair value of warrant liabilities” in the consolidated statements of operations. The fair value of the warrants has been estimated using a Black-Scholes valuation model (see Note 6). Net Loss per Share Basic loss per share is computed by dividing the net income or loss applicable to common shares by the weighted average number of common shares outstanding during the period. Net income (loss) attributable to common stockholders includes the effect of the deemed capital contribution on extinguishment of preferred stock and the deemed dividend related to the immediate accretion of beneficial conversion feature of convertible preferred stock. Diluted earnings per share is computed using the weighted average number of common shares and, if dilutive, potential common shares outstanding during the period. Potential common shares consist of the incremental common shares issuable upon the exercise of stock options (using the treasury stock method) and the conversion of the Company’s convertible preferred stock and warrants (using the if-converted method). Diluted loss per share excludes the shares issuable upon the conversion of preferred stock and the exercise of stock options and warrants from the calculation of net loss per share if their effect would be anti-dilutive. Securities that could potentially dilute loss per share in the future that were not included in the computation of diluted loss per share at March 31, 2017 and 2016 are as follows: As of March 31, 2017 2016 Convertible preferred stock 2,926 217,119 Warrants to purchase common stock 1,251,709 2,304,333 Options to purchase common stock 309,037 289,380 Total 1,563,672 2,810,832 Recent Accounting Pronouncements In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers” (“ASU 2014-09”), which requires entities to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. The new guidance also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. The FASB has subsequently issued ASU No. 2016-10, Revenue from Contracts with Customer (Topic 606) Identifying Performance Obligations and Licensing to address issues arising from implementation of the new revenue recognition standard. ASU 2014-09 and ASU 2016-10 are effective for interim and annual periods beginning January 1, 2018, and may be adopted earlier, but not before Janaury 1, 2017. The revenue standards are required to be adopted by taking either a full retrospective or a modified retrospective approach. The Company is currently evaluating the impact that ASU 2014-09 and 2016-10 will have on the Company’s financial statements and determining the transition method, including the period of adoption, that it will apply. In January 2016, the FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) Leases (Topic 840) In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows - Classification of Certain Cash Receipts and Cash Payments In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Goodwill Impairment Recently Adopted Accounting Pronouncements In March 2016, the FASB issued ASU No. 2016-09, Compensation-Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting

Pursuant to the Monetization Agreement, the Company has worked together with Equitable to develop and revise the Company’s ongoing litigation plan. Under the Monetization Agreement, Equitable is obligated to use its best, commercially reasonable efforts to monetize the Company’s patents. To that end, Equitable has filed several litigations, six of which are currently pending. The Company will share net monetization revenue derived from all monetization activity equally with Equitable. To facilitate the litigation plan, approximately 186 of over 330 of the Company’s patents and applications have been assigned to Equitable, which will pay all maintenance and prosecution fees going forward. No assigned patents may be transferred by Equitable to a third party without the Company’s consent. In the event that all terms of the Monetization Agreement are met by December 2017, the Company will further assign approximately 140 additional patents and applications to Equitable for monetization. The Company has retained a grant-back license to practice all transferred patents. The Company concluded that the Monetization Agreement did not constitute a sale of the patents. The Company’s retention of the right to use the patents, the requirement for the Company’s consent to any sale, and the significant economic benefits the Company retained with respect to the litigation, licensing, and sale proceeds, did not meet the sale of patent criteria. The Monetization Agreement has been treated as an agreement to outsource its licensing activities to an outside servicer, for contingent fees based on the success of the servicer’s efforts. As such, the Company will not remove the patents from its consolidated balance sheet, and will record its share of litigation, licensing, and sales proceeds, if any, when those proceeds are received, or when due if the other revenue recognition criteria are met under ASC 605, Revenue Recognition

Fair Value of Financial Assets

Fair Value Disclosures [Abstract]
Fair Value of Financial Assets and Liabilities	Note 5. Fair Value of Financial Assets and Liabilities Financial instruments, including cash and cash equivalents, accounts and other receivables, accounts payable and accrued liabilities are carried at cost, which management believes approximates fair value due to the short-term nature of these instruments. The Company measures the fair value of financial assets and liabilities based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. The Company uses three levels of inputs that may be used to measure fair value: Level 1 - quoted prices in active markets for identical assets or liabilities Level 2 - quoted prices for similar assets and liabilities in active markets or inputs that are observable Level 3 - inputs that are unobservable (for example, cash flow modeling inputs based on assumptions) The following table presents the Company’s assets and liabilities that are measured at fair value at March 31, 2017 and December 31, 2016 ($ in thousands): Fair value measured at March 31, 2017 Total carrying value at March 31, Quoted prices in active markets Significant other observable inputs Significant unobservable inputs 2017 (Level 1) (Level 2) (Level 3) Assets Marketable securities - corporate bonds and mutual funds $ 5,083 $ 480 $ 4,603 $ - Liabilities Fair value of warrant liabilities $ 824 $ - $ - $ 824 Fair value measured at December 31, 2016 Total carrying value at December 31, Quoted prices in active markets Significant other observable inputs Significant unobservable inputs 2016 (Level 1) (Level 2) (Level 3) Assets Marketable securities - corporate bonds $ 6,025 $ 211 $ 5,814 $ - Liabilities Fair value of warrant liabilities $ 702 $ - $ - $ 702 There were no transfers between Level 1, 2 or 3 during the three months ended March 31, 2017. Level 2 Valuation Techniques The fair values of Level 2 marketable securities are determined using quoted market prices from daily exchange traded markets based on the closing prices as of March 31, 2017 and December 31, 2016. Level 3 Valuation Techniques Level 3 financial liabilities consist of the warrant liabilities for which there is no current market for these securities such that the determination of fair value requires significant judgment or estimation. Changes in fair value measurements categorized within Level 3 of the fair value hierarchy are analyzed each period based on changes in estimates or assumptions and recorded as appropriate. A significant decrease in the volatility or a significant decrease in the Company’s stock price, in isolation, would result in a significantly lower fair value measurement. Changes in the values of the warrant liabilities are recorded in “change in fair value of warrant liabilities” in the Company’s consolidated statements of operations. On July 21, 2015, the Company issued the July 2015 Warrants to purchase an aggregate of 370,263 shares of common stock to the investors in the July 2015 Financing. The July 2015 Warrants became exercisable on January 22, 2016 for a period of 5 years at an exercise price of $8.17 per share. The warrants require, at the option of the holder, a net-cash settlement following certain fundamental transactions (as defined in the July 2015 Warrants) at the Company and therefore are classified as liabilities. The July 2015 Warrants have been recorded at their fair value using the Black-Scholes valuation model, and will be recorded at their respective fair value at each subsequent balance sheet date. This model incorporates transaction details such as the Company’s stock price, contractual terms, maturity, risk free rates, as well as volatility. On December 7, 2015, the Company issued Series A warrants to purchase up to 1,052,624 shares of common stock and Series B warrants to purchase up to 842,099 shares of common stock contained in such offering. Series A Warrants had an exercise price of $3.80 per share and were exercisable at any time between December 7, 2015 and May 6, 2016. 852,624 shares of Series A warrants expired unexercised on May 24, 2016, and no Series A Warrants remain outstanding as of December 31, 2016. Series B Warrants have an exercise price of $4.75 per share and are exercisable at any time between December 7, 2015 and December 6, 2020. The Warrants require the issuance of registered shares upon exercise, do not expressly preclude an implied right to cash settlement and are therefore accounted for as derivative liabilities. The Company classifies these derivative warrant liabilities on the consolidated balance sheet as a current liability. The Series B warrants have been recorded at their fair value using the Black-Scholes valuation model, and will be recorded at their respective fair value at each subsequent balance sheet date. This model incorporates transaction details such as the Company’s stock price, contractual terms, maturity, risk free rates, as well as volatility. A summary of quantitative information with respect to the valuation methodology and significant unobservable inputs used for the Company’s warrant liabilities that are categorized within Level 3 of the fair value hierarchy at the date of issuance and as of March 31, 2017 is as follows: Date of valuation March 31, 2017 Risk-free interest rate 1.93 % Expected volatility 98.22% - 131.41 % Expected life (in years) 3.69 - 3.81 Expected dividend yield - The risk-free interest rate was based on rates established by the Federal Reserve. For the July 2015 Warrants, the expected volatility in the Black-Scholes model is based on an expected volatility of 100% for both periods which represents the percentage required to be used when valuing the cash settlement feature as contractually stated in the form of warrant. The general expected volatility is based on standard deviation of the Company’s underlying stock price's daily logarithmic returns. The expected life of the warrants was determined by the expiration date of the warrants. The expected dividend yield was based upon the fact that the Company has not historically paid dividends on its common stock, and does not expect to pay dividends on its common stock in the future. The following table sets forth a summary of the changes in the fair value of the Company’s Level 3 financial liabilities that are measured at fair value on a recurring basis as of March 31, 2017 and 2016 ($ in thousands): Fair Value of Level 3 financial liabilities March 31, 2017 March 31, 2016 Beginning balance $ 702 $ 2,959 Fair value adjustment of warrant liabilities 122 (1,542 ) Ending balance $ 824 $ 1,417

Rpx License Agreement
RPX License Agreement	Note 6. RPX License Agreement On November 23, 2015, the Company and RPX Corporation (“RPX”) entered into a Patent License Agreement (the “RPX License Agreement”) under which the Company granted RPX the right to sublicense various patent license rights to certain RPX clients. The consideration to the Company included: (i) the transfer to the Company for cancellation of its remaining outstanding Series I Redeemable Convertible Preferred Stock (the “Series I Preferred Stock”), as to which a $5,000,000 mandatory redemption payment would have been due from the Company on or by December 31, 2015; (ii) the transfer to the Company for cancellation of 13%, or 57,076 shares, of its Series H Convertible Preferred Stock (the “Series H Preferred Stock”) then held by RPX, having a total carrying amount of $4,765,846 at the time the stock was issued to Rockstar; (iii) cancellation of the only outstanding security interest on 101 of the Company’s patents and patent applications that originated at Nortel Networks (“Nortel”) and were purchased by the Company from Rockstar, which security interest had previously been transferred to RPX by Rockstar (“RPX Security Interest”); and (iv) $300,000 in cash to the Company. While the license granted to RPX is non-exclusive and the duration of the license is for the life of the patents, the Company’s ongoing obligations in the arrangement is to provide certain specific RPX licensors with a non-exclusive license to any new patents that may be acquired by or exclusively licensed to the Company during the two-year period following the effective date of the agreement. Therefore, the Company will recognize $0.6 million revenue ratably over the two-year period that it is obligated to provide these RPX licensees with licenses to such new patents. During the year ended December 31, 2016 and 2015, the Company recorded approximately $290,000 and $31,000, respectively, in revenue related to the amortization of the license. On May 23, 2016, the Company, and RPX, entered into a second, separate, Patent License Agreement (the “RPX License”) under which the Company granted RPX the right to sublicense various patent rights only to current RPX clients (as of May 23, 2016). In exchange for the rights granted by the Company under the RPX License, the Company received the following consideration: (i) a cash payment made to the Company in May 2016 in the amount of $4,355,000; and (ii) cancellation of 100% of the remaining 381,967 shares of the Company’s outstanding Series H Convertible Preferred Stock currently held by RPX, having a total carrying amount of $31,894,244 at the time the stock was issued to Rockstar Consortium US LP (“Rockstar”). In consideration of the above, the Company granted RPX the rights to grant to its current clients: (i) a fully paid portfolio license, to the extent such parties did not already have licenses to the Company’s patents; (ii) a covenant-not-to-sue current RPX clients for supply of chipsets; (iii) a standstill of litigation involving any patents acquired in the next five years (“Standstill”). The Company also granted to Alcatel-Lucent a license to the portfolio acquired from the Harris Corporation. Under a separate agreement between the Company and RPX, the Company granted RPX the ability to grant to VTech Telecommunications Ltd. (“VTech”) a sublicense for a fully paid portfolio license in exchange for an additional $20,000 in cash consideration. The license granted under the terms of the RPX License described herein does not extend to entities/companies that are not clients of RPX and provide chipsets or other hardware to current RPX clients. The carrying value of Series H Convertible Preferred Stock on the extinguishment date was estimated at approximately $31.9 million. The fair value on the same date was estimated at approximately $414,000 based upon equivalent common shares that the Series H Convertible Preferred Stock could have converted into at the closing price on May 23, 2016. This resulted in the Company receiving cash from RPX of $4.4 million, a deemed capital contribution of approximately $31.5 million, short term deferred revenue $1.1 million and long term deferred revenue of $3.7 million. A summary of information with respect the RPX transaction on May 23, 2016 is as follows: Assumptions Stock price on May 22, 2016 $ 2.06 Series H Assumptions Series H Shares 381,967 Series H - Liquidation preference $ 83.50 Series H -Carrying value $ 31,894,245 Equivalent common shares - Series H 201,035 Fair Value of Series H preferred $ 414,133 Contribution/Deemed dividend $ 31,480,112 The deferred revenue will be amortized over a 5-year service period as the RPX License includes a standstill agreement which requires Spherix to provide the licensee with the right to use any future acquired patents for five years. During the three months ended March 31, 2017, the Company recorded approximately $307,000 in revenue related to the amortization of the license.

Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Nuta Technology Corp. (“Nuta”), Spherix Portfolio Acquisition II, Inc. (“SPXII”), Guidance IP, LLC (“Guidance”), Directional IP, LLC (“Directional”), Spherix Management Services, LLC (“SMS”) and NNPT, LLC (“NNPT”). All significant intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“US GAAP”). This requires management to make estimates and assumptions that affect certain reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the period. The Company’s significant estimates and assumptions include the recoverability and useful lives of long-lived assets, stock-based compensation, the valuation of derivative liabilities, and the valuation allowance related to the Company’s deferred tax assets. Certain of the Company’s estimates, including the carrying amount of the intangible assets, could be affected by external conditions, including those unique to the Company and general economic conditions. It is reasonably possible that these external factors could have an effect on the Company’s estimates and could cause actual results to differ from those estimates and assumptions.
Marketable Securities	Marketable Securities Marketable securities are classified as trading and are carried at fair value. The Company’s marketable securities consist of corporate bonds and highly liquid mutual funds and exchange-traded & closed-end funds which are valued at quoted market prices. During the three months ended March 31, 2017 and 2016, the Company incurred realized losses of approximately $93,000 and $66,000, respectively, and unrealized gains of approximately $72,000 and $12,000, respectively, on its investments in marketable securities, which are included in other income, net on the consolidated statements of operations. In addition, during the three months ended March 31, 2017 and 2016, the Company earned dividend income of approximately $8,000 and $13,000, respectively, which is included in other income, net on the consolidated statement of operations. The Company reinvested such dividend income into its marketable securities during the three months ended March 31, 2017 and 2016. The market value of marketable securities held as of March 31, 2017 and December 31, 2016 were $5.1 million and $6.0 million, respectively.
Accounting for Warrants	Accounting for Warrants The Company accounts for the issuance of common stock purchase warrants issued in connection with the equity offerings in accordance with the provisions of ASC 815, Derivatives and Hedging (“ASC 815”). The Company classifies as equity any contracts that (i) require physical settlement or net-share settlement or (ii) gives the Company a choice of net-cash settlement or settlement in its own shares (physical settlement or net-share settlement). The Company classifies as assets or liabilities any contracts that (i) require net-cash settlement (including a requirement to net-cash settle the contract if an event occurs and if that event is outside the control of the Company) or (ii) gives the counterparty a choice of net-cash settlement or settlement in shares (physical settlement or net-share settlement). In addition, Under ASC 815, registered common stock warrants that require the issuance of registered shares upon exercise and do not expressly preclude an implied right to cash settlement are accounted for as derivative liabilities. The Company classifies these derivative warrant liabilities on the consolidated balance sheet as a current liability. The Company assessed the classification of common stock purchase warrants as of the date of each offering and determined that such instruments met the criteria for liability classification. Accordingly, the Company classified the warrants as a liability at their fair value and adjusts the instruments to fair value at each reporting period. This liability is subject to re-measurement at each balance sheet date until the warrants are exercised or expired, and any change in fair value is recognized as “change in the fair value of warrant liabilities” in the consolidated statements of operations. The fair value of the warrants has been estimated using a Black-Scholes valuation model (see Note 6). Net Loss per Share Basic loss per share is computed by dividing the net income or loss applicable to common shares by the weighted average number of common shares outstanding during the period. Net income (loss) attributable to common stockholders includes the effect of the deemed capital contribution on extinguishment of preferred stock and the deemed dividend related to the immediate accretion of beneficial conversion feature of convertible preferred stock. Diluted earnings per share is computed using the weighted average number of common shares and, if dilutive, potential common shares outstanding during the period. Potential common shares consist of the incremental common shares issuable upon the exercise of stock options (using the treasury stock method) and the conversion of the Company’s convertible preferred stock and warrants (using the if-converted method). Diluted loss per share excludes the shares issuable upon the conversion of preferred stock and the exercise of stock options and warrants from the calculation of net loss per share if their effect would be anti-dilutive. Securities that could potentially dilute loss per share in the future that were not included in the computation of diluted loss per share at March 31, 2017 and 2016 are as follows: As of March 31, 2017 2016 Convertible preferred stock 2,926 217,119 Warrants to purchase common stock 1,251,709 2,304,333 Options to purchase common stock 309,037 289,380 Total 1,563,672 2,810,832
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers” (“ASU 2014-09”), which requires entities to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. The new guidance also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. The FASB has subsequently issued ASU No. 2016-10, Revenue from Contracts with Customer (Topic 606) Identifying Performance Obligations and Licensing to address issues arising from implementation of the new revenue recognition standard. ASU 2014-09 and ASU 2016-10 are effective for interim and annual periods beginning January 1, 2018, and may be adopted earlier, but not before Janaury 1, 2017. The revenue standards are required to be adopted by taking either a full retrospective or a modified retrospective approach. The Company is currently evaluating the impact that ASU 2014-09 and 2016-10 will have on the Company’s financial statements and determining the transition method, including the period of adoption, that it will apply. In January 2016, the FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) Leases (Topic 840) In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows - Classification of Certain Cash Receipts and Cash Payments In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Goodwill Impairment
