Notes to Financial Statements
1. Organization and Description of Business	Organization Until the sale of Spherix Consulting, Inc. (“Spherix Consulting”) in December 2012, the principal segments of Spherix Incorporated and Subsidiaries (the “Company”) have been Biospherics Incorporated, the biotechnology research and development business, and Spherix Consulting, the technical and regulatory consulting business. On December 3, 2012, the Company sold all of the stock of Spherix Consulting, accordingly, the operations of Spherix Consulting are reported in the accompanying consolidated financial statements as discontinued operations. The Company is incorporated in the state of Delaware and 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 in 2012. The Company has shifted its focus during 2013 and is now an intellectual property company that owns patented and unpatented intellectual property. On September 21, 2012, the Company effected a reverse stock split of its outstanding common stock at an exchange ratio of 1-for-20. As a result of the reverse stock split, every 20 shares of the Company’s issued and outstanding common stock were combined into one share of common stock. No fractional shares of common stock were issued as a result of the reverse stock split. Instead, fractional shares that would otherwise result from the reverse stock split were purchased by the Company based on the closing price of the stock on September 21, 2012. All references in these notes and in the related consolidated financial statements to number of shares, price per share and weighted average number of shares outstanding of common stock prior to the reverse stock split (including the share capital decrease) have been adjusted to reflect the reverse stock split (including the share capital decrease) on a retroactive basis, unless otherwise noted. Acquisition of North South Holdings, Inc. On December 27, 2012, the Company formed a new wholly-owned subsidiary, Nuta Technology Corp., (“Nuta”), which is incorporated in the state of Virginia. On April 2, 2013, the Company entered into an Agreement and Plan of Merger, as amended (the "Merger Agreement") with its wholly owned subsidiary, Nuta, North South Holdings, Inc., a Delaware corporation ("North South"), the owner or assignee of certain patents, licenses and applications (the “North South Intellectual Property”), and the shareholders of North South (the "North South Shareholders"). On September 10, 2013 the transaction contemplated under the Merger Agreement was completed (the “Merger”). At closing, North South merged with and into Nuta with Nuta as the surviving corporation. Nuta will continue its operations in the State of Virginia as the record owner of the North South’s intellectual property. Pursuant to the terms and conditions of the Merger, at the closing of the Merger, all of North South’s 5,213 issued and outstanding shares of common stock were converted into an aggregate of 1,203,153 shares of the Company’s common stock, par value $0.0001 per share (the “Common Stock”), and all of North South’s 491 issued and outstanding shares of Series A Preferred Stock and 107 issued and outstanding shares of Series B Preferred Stock were converted into an aggregate of 1,379,685 shares of the Company's Series D Convertible Preferred Stock, par value $0.0001 per share, which is convertible into shares of the Company’s common stock on a one-for-ten basis (collectively with the 1,203,153 common shares of the Company, the “Merger Consideration”). The closing of the Merger was subject to customary closing conditions, including the receipt of a fairness opinion that the Merger Consideration is fair to stockholders and the Company from a financial point of view, based on, among other things, the North South Intellectual Property assets, and the approval of the Company’s shareholders holding a majority of the outstanding voting capital stock of the Company as of the record date (July 10, 2013) to issue the Merger Consideration pursuant to NASDAQ listing standards. Acquisition of Patents from Rockstar Consortium US LP – July 2013 On July 24, 2013, the Company purchased a group of patents in the mobile communication sector (the “Purchased Patents”) from Rockstar Consortium US LP, a Delaware limited partnership (“Rockstar”) at a contractual price of $4.0 million. In consideration for the Purchased Patents, the Company paid an aggregate $3.0 million in consideration to Rockstar, which consisted of a $2.0 million cash payment and 176,991 shares of common stock accepted by the seller in settlement of the $1 million (at $5.65 per share) remaining balance. The Shares are subject to a lock-up agreement, subject to certain leak-out provisions, which shall expire on the earlier of (i) six months from the issuance of the shares or (ii) the date that the Company’s Common Stock achieves a trading volume of at least 50,000 shares per day and a closing price of at least $15 per share for a period of five consecutive days. The Company has filed a registration statement covering the resale of the shares issued to Rockstar with the Securities and Exchange Commission (the “SEC”) on September 5, 2013. On the anniversary of one year and one day after the Company files its first complaint against a defendant with any one or more of the patents acquired in this transaction, the Company shall deliver $1.0 million to Rockstar. The initial complaint was filed on August 30, 2013, and at that time the additional $1.0 million was accrued and included in patent portfolio on the consolidated balance sheet. On January 3, 2014, the Company remitted the $1.0 million to Rockstar in satisfaction of this liability. Acquisition of Patents from Rockstar Consortium US LP – December 2013 On December 31, 2013, through the Company’s wholly-owned subsidiary, Spherix Portfolio Acquisition II, Inc., (“SPA II, Inc.”), the Company entered into its second agreement to acquire certain patents from Rockstar. The Company acquired a suite of 101 patents and patent applications pursuant to a Patent Purchase Agreement in several technology families, including data, optical and voice technology. The patents provide the Company with rights to develop and commercialize products as well as enforcement rights for past, present and future infringement. In connection with the patent acquisition, on December 31, 2013, the Company issued (a) 199,990 shares of common stock with a grant date fair value of approximately $1.7 million, or $8.35 per share, (b) 459,043 shares of Series H Convertible Preferred Stock with a grant date fair value of approximately $38.3 million, or $8.35 per share, and (c) 119,760 shares of Series I Convertible Preferred Stock with a mandatory redemption value of $20 million, or $167 per share, for an aggregate value of approximately $60 million in securities issued to Rockstar. Holders of 50.1% of the outstanding common stock of the Company entered into voting agreements to vote in favor of approving the issuance as the Company was required to obtain stockholder approval pursuant to NASDAQ Listing Rule 5635. Irrespective of the stockholder approval vote, Rockstar is still restricted from transferring or selling any securities for an additional 180 day period following the occurrence of certain Company events (but not more than two such Company events), including the consummation of a public offering in which we receive gross proceeds of at least $5 million and the announcement of any material acquisition.
