Until the sale of Spherix Consulting, Inc. in December 2012, the Company’s principal segments of Spherix Incorporated (the “Company”) have been Biospherics, our biotechnology research and development business, and Spherix Consulting, our technical and regulatory consulting business. On December 3, 2012, the Company sold all of the stock of Spherix Consulting, Inc. Accordingly, the operations of Spherix Consulting, Inc. are reported in the accompanying condensed consolidated financial statements as discontinued operations. The Company is an intellectual property company that owns patented and unpatented intellectual property. We were formed in 1967 as a scientific research company and for much of our history pursued drug development including through Phase III clinical studies which were discontinued in 2012.

On December 27, 2012, the Company formed a new wholly-owned subsidiary, Nuta Technology Corp., (“Nuta”), which is incorporated in the state of Virginia.

Upon closing of the transaction contemplated under the Merger Agreement (the "Merger"), North South will merge with and into Nuta with Nuta as the surviving corporation. Nuta will operate as the record owner of the North South Intellectual Property. The closing of the Merger is subject to customary closing conditions, including the receipt of a fairness opinion that the Merger Consideration (as defined below) 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.
