Item 9B.  Other Information

On March 1,  2007,  Citigroup  Inc.  ("Citigroup")  acquired  ABN AMRO  Mortgage
Corporation  ("AAMC")  from LaSalle Bank  Corporation  ("LaSalle")  as part of a
larger  acquisition of the residential  mortgage loan  origination and servicing
business of ABN AMRO Mortgage Group.

In April 2007,  Citigroup learned that the Class B-3 Certificates  issued in the
Series 1999-RS1 transaction are currently listed on the New York Stock Exchange.
Citigroup  promptly  sought  information  from  LaSalle and the  current  Series
1999-RS1  trustee,  The Bank of New York  ("BNY"),  regarding  past and  ongoing
compliance with reporting obligations under the Securities Exchange Act of 1934,
but it was  determined  that no Exchange Act reports were being filed for Series
1999-RS1.  The Series  1999-RS1  pooling and  servicing  agreement  requires the
trustee to file any required  Exchange Act reports unless otherwise  notified by
AAMC.  LaSalle  has  confirmed  that AAMC did not at any time notify the current
Series 1999-RS1  trustee or any predecessor  trustee to refrain from making such
filings.

Citigroup  has since  instructed  BNY to commence  timely  filing for the Series
1999-RS1  transaction  beginning with the March 2007 monthly report due in April
2007, and to file the delinquent monthly reports beginning with the January 2006
monthly report.  Each of these monthly reports was filed on a Form 8-K report on
or before May 30, 2007 under the Central Index Key (CIK) number (0001091360) for
the Series 1999-RS1 transaction.


                                    PART III


The following items have been omitted in reliance on the Relief Letters:

Item 10.  Directors, Executive Officers and Corporate Governance
Item 11.  Executive Compensation
Item 13.  Certain Relationships and Related Transactions, and Director
          Independence

Item 12.  Security Ownership of Certain Beneficial Owners and Management
          and Related Stockholder Matters

          (a)  Item 201(d) of Regulation S-K:  Not applicable.
          (b)  Item 403 of Regulation S-K:  Omitted in reliance on the Relief
               Letters.

Item 14.  Principal Accountant Fees and Services

Not applicable.

                                     PART IV
