Item 5.07 Submission of Matters to a Vote of Security Holders

On July 24, 2012, Signature Group Holdings, Inc. (the “Company”), held its annual meeting of stockholders (the “Annual Meeting”). The preliminary voting results for each of the proposals submitted to a vote at the Annual Meeting, as provided to the Company by its independent inspector of election, IVS Associates, Inc., on July 27, 2012, are set forth below. These results are only preliminary and are subject to change. On the record date for the Annual Meeting, there were 119,931,857 shares of Company common stock issued, outstanding and entitled to vote. Stockholders holding 104,055,041 shares of Company common stock were present at the Annual Meeting, in person or represented by proxy. Based on the preliminary voting results, the Company was successful in having each of its recommended director nominees elected at the Annual Meeting and receiving approval for the three (3) Company recommended proposals voted on at the Annual Meeting. The Company’s stockholders: (i) elected the Company’s five (5) director nominees listed below under Proposal 1 to serve as director of the Company for a term that will continue until the 2013 annual meeting of stockholders or until their successors have been elected and qualified; (ii) approved an amendment to the Amended and Restated Signature Group Holdings, Inc. 2006 Performance Incentive Plan (the “2006 Plan”) that increased the authorized number of shares of common stock of the Company that may be issued under the 2006 Plan; (iii) ratified the appointment of Squar, Milner, Peterson, Miranda & Williamson, LLP as the Company’s independent registered public accounting firm; and (iv) approved an adjournment of the Annual Meeting to a later date or dates, if necessary, to permit further solicitation of proxies to approve Proposals 2, which seeks approval of an amendment to the Company’s Amended and Restated Articles of Incorporation to increase the authorized number of shares of Company common stock.

The following tables summarize preliminary voting results by the Company’s stockholders. Because of the contested nature of the Annual Meeting, there were no broker non-votes on any matter submitted to a vote at the Annual Meeting.

According to the preliminary tabulation of voting results, the Company’s stockholders elected the following nominees as directors: G. Christopher Colville, John Koral, Patrick E. Lamb, Craig F. Noell and Philip G. Tinkler. These nominees represented the Board’s entire slate of nominees. The complete preliminary tabulation of voting results for the election of directors is set forth below.

The preliminary voting results disclosed above are not final. The Company will file an amendment to this Current Report on Form 8-K to disclose the final voting results of the Annual Meeting following certification by IVS Associates, Inc.

Item 8.01 Other Events.

On June 20, 2011, The National Credit Union Administration (“NCUA”), the regulator of federal credit unions, acting as liquidator of U.S. Central Federal Credit Union (“U.S. Central”), filed a lawsuit in the U.S. District Court in Kansas for unspecified damages to be proven at trial against the underwriter, issuers and depositors of 29 Residential Mortgage-Backed Securities (“RMBS”) offerings purchased by U.S. Central. NCUA alleges that the defendants violated federal and state securities laws through untrue statements and material omissions in the RMBS offering documents. The lawsuit alleges that U.S. Central invested a total of $1.7 billion in these RMBS offerings. The complaint names Fremont Mortgage Securities Corporation (“FMSC”), a wholly-owned special purpose subsidiary of the Company, as a depositor of $50 million in two RMBS offerings in 2006. On December 20, 2011, the Company filed a Motion to Dismiss. On July 25, 2012, the U.S. District Court issued an order dismissing FMSC from the action with leave to amend. The NCUA has thirty days from the date of the dismissal order to amend its complaint.
