                                   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 March 29, 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 for Regulation AB." 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 29, 2007.

            subject, or any proceedings known to be contemplated by governmental
            authorities against any of the foregoing, that are material to
            security holders.


  Item 1119 of Regulation AB, Affiliations and Certain Relationships and
             Related Transactions.

            Except as may be set forth immediately below and subject to the
            Instruction to Item 1119, there are no affiliations, relationships
            or related transactions specified in Item 1119 that are material to
            security holders. Certain information required by Item 1119 of
            Regulation AB has been omitted from this report in reliance on the
            Instruction to Item 1119.

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

            Except as may be set forth immediately below, all of the reports on
            assessment of compliance with the servicing criteria for
            asset-backed securities and their related attestation reports on
            assessment with servicing criteria for asset-backed securities
            required to be included in this report in accordance with Item 1122
            of Regulation AB and Exchange Act Rules 13a-18 and 15d-18 have been
            included as an exhibit to this report.  Material instances of
            noncompliance with Item 1122, if any are set forth below.

            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 Home Loan Servicing, Inc.
            f/k/a National City Home Loan Services, Inc.) 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 Home Loan Services, Inc. has disclosed
            material noncompliance with SEC Regulation AB Servicing Criteria
            applicable to the Company during the year ended December 31, 2006,
            as follows:

            Item:                      Description of material noncompliance:

            1122 (d)(4)(x) A           For a sample of 60 loans with escrow
                                       accounts, 5 escrow accounts were not
                                       analyzed within a 12 month period.

            1122 (d)(4)(x) C           For a sample of 60 loans with escrow
                                       accounts, escrow funds were not returned
                                       within 30 days after payoff for 2 loans.

            1122 (d)(1)(i)             The Company had not instituted policies
                                       and procedures to monitor any performance
                                       or other triggers in accordance with the
                                       transaction agreements.

            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 Servicer's, Home Loan Services, Inc.
           f/k/a National City Home Loan Services Inc., Assessment of Compliance
           and related Attestation Report did not address each of the servicing
           criteria that the Servicer was required to address under the terms of
           the related Servicing Agreement. The Servicer has 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 Servicer asserts that
           those items are not applicable to the Servicer.





  Item 1123 of Regulation AB, Servicer Compliance Statement.

            Except as may be set forth immediately below, all of the servicing
            compliance statements required to be included in this report in
            accordance with Item 1123 of Regulation AB have been included as an
            exhibit to this report.
