Item 5. Other Events.
<PAGE>
On or about September 24, 1999, the Registrant will cause the issuance and
sale of approximately $400,016,424 initial principal amount of Mortgage
Pass-Through Certificates, Series 1999-6 (the "Certificates") pursuant to a
Pooling and Servicing Agreement dated as of September 1, 1999, among ABN AMRO
Mortgage Corporation, as depositor, Chase Bank of Texas, National Association,
as trustee and ABN AMRO Mortgage Group, Inc., as servicer.
In connection with the sale of the Certificates, the Registrant has been
advised by Lehman Brothers Inc. ("Lehman Brothers"), that Lehman Brothers has
furnished to prospective investors certain yield tables and other computational
materials (the "Computational Materials") with respect to the Certificates
following the effective date of Registration Statements Nos. 333-57027 and
333-87283 which Computational Materials are being filed as exhibits to this
report.
The Computational Materials have been provided by Lehman Brothers. The
information in the Computational Materials is preliminary and may be superseded
by the Prospectus Supplement relating to the Certificates and by any other
information subsequently filed with the Securities and Exchange Commission.
The Computational Materials were prepared by Lehman Brothers at the request
of certain prospective investors, based on assumptions provided by, and
satisfying the special requirements of, such prospective investors. The
Computational Materials may be based on assumptions that differ from the
assumptions set forth in the Prospectus Supplement. The Computational Materials
may not include, and do not purport to include, information based on assumptions
representing a complete set of possible scenarios. Accordingly, the
Computational Materials may not be relevant to or appropriate for investors
other than those specifically requesting them.
In addition, the actual characteristics and performance of the mortgage
loans underlying the Certificates (the "Mortgage Loans") may differ from the
assumptions used in the Computational Materials, which are hypothetical in
nature and which were provided to certain investors only to give a general sense
of how the yield, average life, duration, expected maturity, interest rate
sensitivity and cash flow characteristics of the Certificates might vary under
varying prepayment and other scenarios. Any difference between such assumptions
and the actual characteristics and performance of the Mortgage Loans will affect
the actual yield, average life, duration, expected maturity, interest rate
sensitivity and cash flow characteristics of the Certificates.
