Amendment Description Subsequent to filing its Annual Report on Form 10-K for the year ended December 31, 2012 (the “2012 Form 10-K”) with the Securities and Exchange Commission (the “SEC”) on March 11, 2013, MRI Interventions, Inc. (the “Company”) determined that it should have used derivative liability accounting to account for the fair value of the warrants issued by the Company in its July 2012 equity private placement (the “July 2012 PIPE Financing”) in recording the net proceeds received from that transaction, due to the anti-dilution provision associated with the exercise price of the warrants. The Company previously recorded all of the net proceeds from the July 2012 PIPE Financing as equity. As a result, the Company is filing this Amendment No. 1 to the 2012 Form 10-K (“Amendment No. 1”) for the purpose of restating its financial statements for the year ended December 31, 2012 included in “Item 8. Financial Statements and Supplementary Data,” to correct that non-cash accounting error. See Note 12 to the financial statements included in this Amendment No. 1 for further information relating to the restatements. Conforming changes have been made to “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.” In addition, “Item 9A. Controls and Procedures” has been revised to reflect management’s re-evaluation of the effectiveness of the Company’s disclosure controls and procedures as of December 31, 2012. “Item 15. Exhibits and Financial Statement Schedules” has been amended to include a new consent from the Company’s independent registered public accounting firm as reflected in Exhibit 23.1, and new certificationss as reflected in Exhibits 31.1, 31.2 and 32. Items 7, 8, 9A and 15 of the 2012 Form 10-K are the only portions of the 2012 Form 10-K being amended and restated by this Amendment No. 1. The Company has not otherwise modified or updated disclosures presented in the 2012 Form 10-K, except to reflect the effects of the restatements. This Amendment No. 1 does not reflect events occurring after the original filing date of the 2012 Form 10-K on March 11, 2013, and does not modify or update those disclosures affected by subsequent events, except as specifically referenced herein with respect to the restatements. Information not affected by the restatements is unchanged and reflects the disclosures made at the time of the original filing of the 2012 Form 10-K. Accordingly, this Amendment No. 1 should be read in conjunction with the 2012 Form 10-K and the Company’s filings with the SEC subsequent to the filing of the 2012 Form 10-K. The Company will also file an amended Quarterly Report on Form 10-Q for the quarter ended March 31, 2013 regarding the above-described non-cash accounting error.
