Amendment Description	SCG Financial Acquisition Corp. ("we," "us," or the "Company") is filing this Amendment No. 1 to Quarterly Report on Form 10-Q/A (this "Amendment") to amend and restate its Quarterly Report on Form 10-Q for the period ended March 31, 2012, originally filed on May 14, 2012 (the "Original Filing"). For the convenience of the reader, this Amendment sets forth the Original Filing in its entirety, as amended by the Amendment. However, this Amendment is being filed to (i) amend the disclosure in Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations and (ii) amend and restate the interim financial statements and related disclosure in Item 1. Financial Statements and Supplementary Data. In addition, as required by Rule 12b-15 promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), new certifications by the Company's principal executive officer and principal financial officer are filed as exhibits to this Amendment. This Amendment is being filed to restate our unaudited interim financial statements as of March 31, 2012 to correct the accounting for adjustment made on our warrants. Our original accounting treatment did not recognize a liability for the warrant liability and did not recognize changes in the fair value of that warrant liability in our audited statement of operations. For additional information regarding this restatement, see "Note C - Restatement of Previously Issued Financial Statements" in the Notes to the Financial Statements contained in Item 1. Although this Amendment amends and restates the Original Filing in its entirety, except for the information described above, this Amendment does not reflect events occurring after the filing of the Original Filing and unless otherwise stated herein, the information contained in the Amendment is current only as of the time of the Original Filing. Except as described above, no other changes have been made to the Original Filing. Accordingly, the Amendment should be read in conjunction with the Company's filings made with the Securities and Exchange Commission subsequent to the filing of the Original Filing. The sections of the Original Filing affected by the restatement should no longer be relied upon.
