                                          FORM 10-K/A
                                        Amendment No. 1

The Issuing Entity is filing this Form 10-K/A to replace Exhibits 31, 33(a)
and 34(a) to the original Form 10-K filed on March 30, 2007. American Security
Insurance Company, Standard Guaranty Insurance Company and TrackSure Insurance
Agency, Inc. (formerly, "Safeco Financial Institution Solutions, Inc.")
("Assurant Inc.") recently provided the Issuing Entity with a revised report on
assessment of compliance with servicing criteria for asset-backed securities
and a related attestation. In the original assessment previously provided to
the Issuing Entity, Assurant Inc. excluded Item 1122(d)(4)(xii) from the scope
of its assessment. Assurant Inc. recently provided the Issuing Entity with a
revised assessment of compliance that assesses Assurant Inc.'s compliance with
Item 1122(d)(4)(xii) and identifies material instance of non compliance with
this criterion. This material instance of non compliance is noted in this Form
10-K/A under "Additional Disclosure Items Pursuant to General Instruction J."
The Issuing Entity has included this revised assessment of compliance under
Exhibit 33(a), the related attestation under Exhibit 34(a) and a revised Rule
13a-14(d)/15d-14(d) Certification under Exhibit 31. This Form 10-K/A does not
otherwise amend the original Form 10-K filed with the Commission on
March 30, 2007.

  Item 1122 of Regulation AB, Compliance with Applicable Servicing Criteria.

            See Item 15.

            Assurant, Inc. previously excluded the applicable servicing
            criteria set forth in Item 1122 (d)(4)(xii) from the scope of its
            assessment of compliance. Assurant, Inc. has now assessed its
            compliance with the Applicable Servicing Criteria for the Reporting
            Period of January 1, 2006 through December 31, 2006 and has
            identified a material instance of noncompliance with that servicing
            criterion. Specifically, Assurant, Inc. did not have, during the
            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). Accordingly,
            Assurant, Inc. has restated its previous assessment for the
            Reporting Period, which excluded evaluation of the criterion,
            to include the criterion and reflect the material noncompliance as
            a result of its assessment.

            The 1122 statements for First American Real Estate Solutions of
            Texas, L.P. (as Sub-Contractor for Ocwen Loan Servicing, LLC) has
            disclosed the following material instance of noncompliance with
            the servicing criteria set forth in Item 1122(d)(2)(vii)(B) of
            Regulation AB applicable to the Company during year ended
            December 31, 2006. Account reconciliations for all asset-backed
            securities related bank accounts were not prepared within 30
            calendar days after the bank statement cutoff date, or such other
            number of days specified in the transaction agreements as required
            by Item 1122(d)(2)(vii)(B) of Regulation AB.

            The 1122 statements for Wells Fargo Bank, National Association
            (Corporate Trust Services) has disclosed material noncompliance with
            criterion 1122(d)(3)(i), as applicable to the Company during the
            twelve months ended December 31, 2006. Certain monthly investor or
            remittance reports included errors in the calculation and/or the
            reporting of delinquencies for the pool assets.

  Item 1123 of Regulation AB, Servicer Compliance Statement.
