FORM 8-K

CURRENT REPORT

Pursuant to Section 13 OR 15(d) of The Securities Exchange Act of 1934

Item 4.01  Changes in Registrant’s Certifying Accountant

On April 18, 2013, Spherix Incorporated (the “Company”) dismissed the Company’s independent registered public accounting firm Grant Thornton LLP (“Grant Thornton”) effective immediately.  The dismissal was recommended by the Audit Committee and approved by the Board of Directors (the “Board”) of the Company.

Grant Thornton’s reports on the financial statements of the Company for the years ended December 31, 2012 and 2011 did not contain any adverse opinion or a disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope, or accounting principles.

In connection with the audits of the fiscal years ended December 31, 2012 and 2011 and through April 18, 2013, there were (1) no disagreements with Grant Thornton on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements if not resolved to the satisfaction of Grant Thornton would have caused Grant Thornton to make reference to the subject matter of the disagreement(s) in connection with its reports; and (2) one “reportable event” as such term is defined in Item 304(a)(1)(v) of Regulation S-K in that there was a material weakness in the internal control over financial reporting as disclosed in the Form 10-K for fiscal year ended December 31, 2012.  There were no other “reportable events.”

The Company has provided Grant Thornton with a copy of this Form 8-K prior to its filing with the Securities and Exchange Commission (the “SEC”), and has requested that Grant Thornton furnish a letter addressed to the SEC stating whether or not it agrees with the above statements and, if not, stating the respects in which it does not agree.  A copy of such letter, dated April 24, 2013, indicating that Grant Thornton is in agreement with such disclosures, is filed as Exhibit 16.1 to this Form 8-K.

On April 18, 2013, the Company engaged Marcum LLP (“Marcum”) as the Company’s independent registered public accountant effective immediately.  The engagement was approved by the Board.  During the fiscal years ended December 31, 2012 and 2011 and through April 18, 2013, the Company did not consult with Marcum regarding (1) the application of accounting principles to a specified transaction, (2) the type of audit opinion that might be rendered on the Company’s financial statements, (3) written or oral advice provided that would be an important factor considered by the Company in reaching a decision as to an accounting, auditing or financial reporting issue, or (4) any matter that was the subject of a disagreement between the Company and its predecessor auditor as described in Item 304(a)(1)(iv) or a reportable event as described in Item 304(a)(1)(v) of Regulation S-K.
