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. 500,000 750,000 750,000 625,002 IMT comprises the microwave brands Nucomm and RF Central offering customers worldwide complete video solutions.

The xG subsidiary, Integrated Microwave Technology, LLC was formed in February 2016 as a Delaware limited liability company. On September 28, 2015, the Company received a written notification from the Nasdaq Capital Market (“Nasdaq”) indicating that the Company was not in compliance with Nasdaq Listing Rule 5550(a)(2) relating to the minimum bid requirements as the Company’s closing bid price was below $ 1.00 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 generally accepted 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 June 30, 2016, the results of its operations for the three and six months ended June 30, 2016 and 2015, and the results of its cash flows for the six months ended June 30, 2016 and 2015. Such adjustments are of a normal recurring nature. The results of operations for the three and six months ended June 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 June 30, 2016 and 2015 excludes the potentially dilutive securities for 1.4 0.01 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.
