UNITED STATES
                             SECURITIES AND EXCHANGE COMMISSION
                                   WASHINGTON, D.C. 20549



                                        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 April 2, 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 April 2, 2007.

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


            The servicing criteria have been completed within the manner stated
            in the governing documents and are attached hereto under 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 GreenPoint Mortgage Funding, Inc. has
            disclosed the following material noncompliance with servicing
            criteria 1122(d)(1)(i), 1122(d)(2)(iv), and 1122(d)(3)(ii)
            applicable to the Company's platform covered by this report
            during the year ended December 31, 2006. 1122(d)(1)(i) - There
            were no policies and procedures instituted to monitor the
            performance or other triggers and events of defaults in
            accordance with the transaction agreements; 1122(d)(2)(iv) - The
            related accounts for each transaction were not separately
            maintained as set forth in the transaction agreements; and,
            1122(d)(3)(ii) - Amounts due to investors were not remitted in
            accordance with the timeframes set forth in the transaction
            agreements.

             The 1122 statements for Wells Fargo Bank, N.A. (servicer) has
            disclosed the following instances of material noncompliance with
            certain servicing criteria applicable to the Company during the year
            ended December 31, 2006:

            1. 1122(d)(3)(i) - Delinquency Reporting - The Company provided
               incomplete data to some third parties who use such data to
               calculate delinquency ratios and determine the status of loans
               with respect to bankruptcy, foreclosure or real estate owned.
               Instead of the actual due date being provided for use in
               calculating delinquencies, the date of the first payment due to
               the security was provided.

            2. 1122(d)(4)(vii) - Notification of Intent to Foreclose - The
               Company, as required by certain servicing agreements, did not
               provide investors with prior notification of intent to foreclose.


           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.


            Although each servicing criterion required by Item 1122(d) of
            Regulation AB is addressed in one or more of the Assessments of
            Compliance with Servicing Criteria and related Attestation Reports
            included with this report, the Servicers', GMAC Mortgage, LLC f/k/a
            GMAC Mortgage Corporation, and GreenPoint Mortgage Funding, Inc.,
            Assessment of Compliance and related Attestation Reports did not
            address each of the servicing criteria that the Servicers were
            required to address under the terms of the related Servicing
            Agreements. The Servicers have not identified such failure to
            provide an Assessment and Attestation for these items as a material
            failure to fulfill its obligations under the related servicing
            agreement in the Servicer's Compliance Statement provided under Item
            1123 of Regulation AB, because the Servicers assert that those items
            are not applicable to the Servicers.


  Item 1123 of Regulation AB, Servicer Compliance Statement.


            The servicer compliance statements have been completed within the
            manner stated in the governing documents and are attached hereto
            under Item 15.
