Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [Text Block] | xG Technology, Inc. (the “Company”), a Delaware corporation, has developed a broad portfolio of innovative intellectual property designed to enhance wireless communications. The Company’s intellectual property is embedded in proprietary software algorithms designed to offer cognitive interference mitigation and spectrum access solutions to organizations in a wide variety of industries, including national defense and rural broadband, which represent the primary vertical markets that the Company is initially targeting. On January 29, 2016, the Company completed the acquisition of certain assets and liabilities that constitute the business of Integrated Microwave Technologies, LLC, a Delaware limited liability company (‘‘IMT’’), pursuant to an asset purchase agreement by and between the Company and IMT (the ‘‘Asset Purchase Agreement’’). Pursuant to the terms of the Asset Purchase Agreement, the Company acquired substantially all of the assets and liabilities of IMT in connection with, necessary for or material to IMT’s business of designing, manufacturing and supplying of Coded Orthogonal Frequency Division Multiplexing (COFDM) microwave transmitters and receivers serving the broadcast, sports and entertainment, military, aerospace and government markets (the ‘‘Transaction’’). The purchase price for the Transaction was $ 3,000,000 1,500,000 March 31, 2016 1,500,000 July 29, 2017 Asset Purchase Modification Agreement (the “Asset Purchase Modification Agreement”) with IMT, which terminated the Payment Notes, cancelling all principal due or to become due thereunder, and in their stead obligated the Company to: (i) upon execution of the Asset Purchase Modification Agreement, pay to IMT $500,000 plus any interest accumulated on the Payment Notes prior to their being cancelled; and (ii) prior to December 31, 2016, deliver to IMT shares (the “Series D Shares”) of the Company’s Series D Convertible Preferred Stock, par value $0.00001 per share, (the “Series D Preferred Stock”) having an aggregate value of cash proceeds (“Cash Proceeds”), upon conversion of such Series D Shares into shares of common stock underlying such Series D Shares, of not less than $2,500,000, plus interest accrued thereon at 9% per annum, with such Series D Shares to be issued in tranches of $250,000 (the “Tranches”). If IMT does not realize Cash Proceeds of at least $2,500,000 by December 31, 2016, the Company will be required to either issue additional shares of common stock to IMT, or otherwise raise additional funds to cover the shortfall. Cash Proceeds are determined by the cash or cash equivalents received by IMT upon sale of the shares of common stock issued to IMT upon conversion of any Series D Shares, net of any transaction costs or expenses. Each time a new Tranche is issued, IMT shall be obligated to provide evidence of its current Cash Proceeds and the remaining amount of the $2,500,000 (plus interest) due. 500,000 5,750,000 3,750,000 3,125,010 IMT comprises the microwave brands Nucomm and RF Central offering customers worldwide complete video solutions. Nucomm is a premium brand of digital broadcast microwave video systems. RF Central is an innovative brand of compact microwave video equipment for licensed and license-free sports and entertainment applications. IMT is a trusted provider of mission-critical wireless video solutions to state, local and federal police departments. The xG subsidiary, Integrated Microwave Technology, LLC was formed in February 2016 as a Delaware limited liability company. On September 29, 2015, the Company received written notice from NASDAQ notifying us that we were not in compliance with the minimum bid price requirement set forth in NASDAQ Listing Rule 5550(a)(2) for continued listing on the NASDAQ, as the closing bid price for the Company’s common stock was 1.00 share for the last thirty (30) consecutive business days. In accordance with NASDAQ listing rules, the Company was afforded 180 calendar days, or until March 28, 2016, to regain compliance with NASDAQ Listing Rule 5550(a)(2). The Company was unable to regain compliance with the bid price requirement by On March 29, 2016, the Company received written notice (the “Notice”) from NASDAQ that it had granted the Company an additional 180 calendar days, or until September 26, 2016, to regain compliance with the minimum bid price requirement of $ 1.00 The NASDAQ determination to grant the second compliance period was based on the Company meeting the continued listing requirement for market value of publicly held shares and all other applicable requirements for initial listing on the NASDAQ, with the exception of the bid price requirement, and the Company’s written notice of its intention to cure the deficiency during the second compliance period by effecting a reverse stock split, if necessary. To regain compliance, the bid price of the Company’s common stock must have a closing bid price of at least $1.00 per share for a minimum of ten (10) consecutive business days at any time during the second 180-day compliance period. On June 20, 2016, the Company effected a 1-for-12 reverse stock split of its outstanding common stock as a measure to regain compliance. On August 19, 2016, the Company filed a Definitive Proxy for a special shareholders meeting to be held on September 22, 2016, asking for the shareholders to grant the Board of Directors approval to execute another reverse stock split, if necessary. The meeting was adjourned to November 16, 2016 to allow additional time for the stockholders to vote on the proposal. On September 27, 2016, the Company received a determination letter (the “Letter”) from the staff of NASDAQ stating that the Company has not regained compliance with the NASDAQ minimum bid price of $1.00 requirement for continued listing set forth in NASDAQ Listing Rule 5550(a)(2). Pursuant to the Letter, unless the Company requests a hearing to appeal this determination by October 4, 2016, the Company’s common stock will be delisted from The Nasdaq Capital Market, trading of the Company’s common stock will be suspended at the opening of business on October 6, 2016, and a Form 25-NSE will be filed with the Securities and Exchange Commission, which will remove the Company’s common stock from listing and registration on Nasdaq. The Company has requested a hearing before a Nasdaq Hearing Panel (the “Panel”). The Company will be asked to provide the Panel with a plan to regain compliance with the minimum bid price requirement of Listing Rule 5550(a)(2). The Company’s plan will need to include a discussion of the events that the Company believes will enable it to timely regain compliance with such requirement. The Company intends to submit a plan that it believes will be sufficient to permit the Company to regain compliance with the minimum bid price requirement. While the appeal process is pending, the suspension of trading of the Company’s common stock is stayed, and the Company’s common stock will continue to trade on Nasdaq until the hearing process concludes and the Panel issues a written decision. There can be no assurance that the Panel will grant the Company’s request for a suspension of delisting or continued listing on Nasdaq. If the Company’s common stock ceases to be listed for trading on The Nasdaq Capital Market, the Company would expect that its common stock would be traded on one of the three tiered marketplaces of the OTC Markets Group. In the event that the Company’s common stock is delisted from the NASDAQ, and is not eligible for quotation on another market or exchange, trading of its common stock could be conducted in the over-the-counter market or on an electronic bulletin board established for unlisted securities such as the Pink Sheet or the OTC Bulletin Board. In such event, it could become more difficult to dispose of, or obtain accurate price quotations for, the Company’s common stock, and there would likely also be a reduction in the Company’s coverage by securities analysts and the news media, which could cause the price of its common stock to decline further. Also, it may be difficult for the Company to raise additional capital if it is not listed on a major exchange. On June 10, 2016, the Company’s Board of Directors (the “Board”) approved a resolution to amend the Company’s Certificate of Incorporation and to authorize the Company to effect a reverse split of the Company’s outstanding common stock at a ratio of 1-for-12. On June 20, 2016, the Company effected the 1-for-12 reverse stock split. Upon effectiveness of the reverse stock split, every 12 shares of outstanding common stock decreased to one share of common stock The accompanying unaudited condensed consolidated financial statements were prepared using accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and the instructions to Form 10-Q and Regulation S-X. Accordingly, these financial statements do not include all information or notes required by GAAP for annual financial statements and should be read in conjunction with the financial statements as filed on the Company's Annual Report on Form 10-K for the year ended December 31, 2015. In the opinion of management, the unaudited condensed consolidated financial statements included herein contain all adjustments necessary to present fairly the Company's financial position as of September 30, 2016, the results of its operations for the three and nine months ended September 30, 2016 and 2015, and the results of its cash flows for the nine months ended September 30, 2016 and 2015. Such adjustments are of a normal recurring nature. The results of operations for the three and nine months ended September 30, 2016 may not be indicative of results for the full year ending December 31, 2016. The condensed consolidated financial statements include the accounts of xG Technology, Inc. and its wholly-owned subsidiary since the date the acquisition of IMT was completed. All intercompany transactions and balances have been eliminated in consolidation. Certain reclassifications have been made in the unaudited consolidated financial statements for comparative purposes. These reclassifications have no effect on the results of operations or financial position of the Company. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates and assumptions include reserves and write-downs related to receivables and inventories, the recoverability of long-lived assets, the valuation allowance relating to the Company’s deferred tax assets, valuation of equity and derivative instruments, and debt discounts and the valuation of the assets and liabilities acquired in the acquisition of IMT. The Company recognizes revenues when persuasive evidence of an arrangement exists, services have been rendered, the price is fixed and determinable, and collectability is reasonably assured. Revenues from management and consulting, time-and-materials service contracts, maintenance agreements and other services are recognized as the services are provided or at the time the goods are shipped and title has passed. The Company computes basic net loss per share by dividing net loss per share available to common stockholders by the weighted average number of common shares outstanding for the period, excluding the effects of any potentially dilutive securities. Diluted loss per share, if presented, would include the dilution that would occur upon the exercise or conversion of all potentially dilutive securities into common stock using the “treasury stock” and/or “if converted” methods as applicable. The computation of basic loss per share at September 30, 2016 and 2015 excludes the potentially dilutive securities for 13.6 0.9 GAAP requires disclosing the fair value of financial instruments to the extent practicable for financial instruments which are recognized or unrecognized in the balance sheet. The fair value of the financial instruments disclosed herein is not necessarily representative of the amount that could be realized or settled, nor does the fair value amount consider the tax consequences of realization or settlement. In assessing the fair value of financial instruments, the Company uses a variety of methods and assumptions, which are based on estimates of market conditions and risks existing at the time. For certain instruments, including, accounts receivable, accounts payable, and accrued expenses, the Company estimated that the carrying amount approximated fair value because of the short maturities of these instruments. All debt is based on current rates at which the Company could borrow funds with similar remaining maturities and approximates fair value. GAAP establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use on unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The hierarchy is described below: Level 1 Quoted prices in active markets for identical assets or liabilities. Level 2 Observable prices that are based on inputs not quoted on active markets, but corroborated by market data. Level 3 Unobservable inputs are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs. Management has evaluated subsequent events or transactions occurring through the date the condensed consolidated financial statements were issued and determined that no events or transactions are required to be disclosed herein, except as disclosed. In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations In March 2016, the FASB issued ASU No. 2016-09, Compensation-Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting companies can recognize them. ASU No. 2016-09 also requires companies to present excess tax benefits as an operating activity on the statement of cash flows rather than as a financing activity. Furthermore, ASU No. 2016-09 will increase the amount an employer can withhold to cover income taxes on awards and still qualify for the exception to liability classification for shares used to satisfy the employer’s statutory income tax withholding obligation. An employer with a statutory income tax withholding obligation will now be allowed to withhold shares with a fair value up to the amount of taxes owed using the maximum statutory tax rate in the employee’s applicable jurisdiction(s). ASU No. 2016-09 requires a company to classify the cash paid to a tax authority when shares are withheld to satisfy its statutory income tax withholding obligation as a financing activity on the statement of cash flows. Under current U.S. GAAP, it was not specified how these cash flows should be classified. In addition, companies will now have to elect whether to account for forfeitures on share-based payments by (1) recognizing forfeitures of awards as they occur or (2) estimating the number of awards expected to be forfeited and adjusting the estimate when it is likely to change, as is currently required. The amendments of this ASU are effective for reporting periods beginning after December 15, 2016, with early adoption permitted but all of the guidance must be adopted in the same period. The Company is currently assessing the impact that ASU No. 2016-09 will have on its condensed consolidated financial statements. In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers In May 2016, the FASB issued ASU No. 2016-12, “Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients” , which narrowly amended the revenue recognition guidance regarding collectability, noncash consideration, presentation of sales tax and transition and is effective during the same period as ASU 2014-09. The Company is currently evaluating the provisions of this standard and assessing its impact on the Company’s condensed consolidated financial statements and disclosures. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows: Clarification of Certain Cash Receipts and Cash Payments The FASB issued ASU 2016-02, Leases (Topic 842) |
