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. 0001375282-
07-000001) by Citigroup Mortgage Loan Trust 2006-AMC1 (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).
