     Explanatory Note

  This Amendment No. 1 to the Annual Report on Form 10-K filed with the
  Securities and Exchange Commission on April 2, 2007 (Accession No.
  0001056404-07-001637) by Citigroup Mortgage Loan Trust 2006-FX1 (the "Initial
  10-K"), for the fiscal year ended December 31, 2006, is being filed for the
  sole purpose of restating the assessment of American Security Insurance
  Company, Standard Guaranty Insurance Company and TrackSure Insurance Agency,
  Inc. (the "Asserting Party") for the reporting period of January 1, 2006
  through December 31, 2006. The restated assessment, provided to the
  registrant in February 2008, identifies a material instance of noncompliance
  with the servicing criteria set forth in Item 1122(d)(4)(xii) under
  Regulation AB. Specifically, the Asserting Party did not have, during the
  applicable reporting period, sufficient policies and procedures to capture
  the information with respect to the Platform Transactions necessary to
  determine compliance with Item 1122(d)(4)(xii). In response to a Securities
  and Exchange Commission comment, as of January 1, 2008, the Asserting Party
  has implemented practices and procedures to capture the information necessary
  to assess compliance with Item 1122(d)(4)(xii).
